Problems solved by technology

In traditional manual assembly, the process of dispensing glue often has problems such as low efficiency, poor precision, difficulty in controlling the amount of glue, uneven quality, and glue tends to gather at a certain place on the screw.
If the dispensing amount of each screw is inconsistent, the assembly quality of the workpiece will be uneven, which will easily cause some screws to have less glue and poor assembly effect, or some screws to have too much glue to cause glue overflow, residue, waste glue, etc.
[0003] In addition to the inconsistent dispensing amount, if the glue is unevenly distributed or aggregated on the screw, it will cause glue residue on the outer surface when screwed into the screw hole for assembly, uneven internal glue distribution after assembly, poor waterproof performance of the screw, and some Screws are easy to rust, etc.

Embodiment 1

[0026] Such as figure 1 with figure 2 As shown, the method for improving the uniformity of glue in the dispensing process of screw assembly includes the following steps,

[0027] Step 1. Pour the screws 9 and copper caps 30 that need to be assembled into the vibrating plate 2 installed on the assembly platform 1 in batches, pour the assembly glue into the glue storage bin 3 installed on the assembly platform 1, The specific structure of the vibrating plate 2 is the common vibrating feeding equipment used by mechanical assembly companies to assemble the screws 29 and the copper caps 30 , and will not be described in detail here.

[0028] Step 2. In the assembly control device installed on the assembly platform 1, set the working parameters of the screw locking device and the glue dispensing device installed on the assembly platform 1. The specific method is as follows:

[0029] The parameters for using the locking screw device to rotate the screw on the assembly control devi...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that the assembly parameters are changed according to the model of the tool assembly, that is, the setting parameter values ​​of A, B, C, D, and E are adaptively adjusted, as follows Said:

[0034] This embodiment is used to assemble an irregular oval multifunctional knife shell with a length of 11.5cm and a width of 3.2cm. The time length is 0.2s, the dispensing volume is 0.02ml, and the dispensing action starts 0.2s later than the screw rotation action. After the screw 29 is in place, the assembly is carried out through the cooperation of the locking screw device and the dispensing device. After the equipment executes the processing parameters and the assembly is completed, the product is obtained. Through random inspection of the product, it is found that there are no problems such as missing glue dispensing and overflowing glue.

[0035] Whether it is the first embodiment or the second embodiment, the speci...

Abstract

The invention discloses a method for improving glue uniformity in a screw assembly dispensing process. The method comprises the following steps: 1, respectively pouring screws and copper caps needing to be assembled into a vibrating disc which is correspondingly mounted on an assembly table in batches, and pouring assembly glue into a glue storage bin mounted on the assembly table; and 2, setting operating parameters for a screw locking device and a dispensing device mounted on the assembly table in an assembly control device arranged on the assembly table; wherein the parameters that the screws are rotated by utilizing the screw locking device on the assembly control device are as follows: the screw rotating speed is A r / s, and the number of turns of the rotating screws is B; and the parameters that dispensing is performed by utilizing the dispensing device on the assembly control device are as follows: the dispensing time duration is Cs, the dispensing quantity is D ml, and the dispensing action is delayed by E s to be started compared with a screw rotating action. Therefore, the distribution uniformity on the assembly glue thread is consistent, dispensing is completed simultaneously when screw rotates, the operations of assembling and dispensing are automatically completed, human intervention is not needed, the assembling quality is high, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of assembling screws and copper caps on cutters, in particular to a method for improving the uniformity of glue in the screw assembling and dispensing process. Background technique [0002] In the processing and production process of hardware products represented by pocket knives, folding knives, multi-function knives, etc., in order to ensure the firmness, durability and certain waterproof performance of these hardware products, it is often necessary to carry out points on the threads when assembling screws. Glue treatment, and then tighten into the screw hole or sleeve. In traditional manual assembly, the process of dispensing glue often has problems such as low efficiency, poor precision, difficulty in controlling the amount of glue, uneven quality, and glue tends to gather at a certain place on the screw. If the dispensing amount of each screw is inconsistent, the assembly quality of the workpiece will ...
