Dispensing processing method for sealing rubber strip of waterproof type-c connector

Abstract

A dispensing processing method for a sealing rubber strip of a waterproof type-c connector comprises the following steps of A, dispensing machine preparation, wherein UV semi-cured glue is injected into an injection dispensing machine, and the optimal air pressure and the optimal temperature are adjusted; B, dispensing starting, wherein a dispensing head of the injection dispensing machine is aligned to a glue groove and made to move at a constant speed along the outline of the glue groove, and in the process, the dispensing head injects glue into the glue groove until the glue groove is filled up with the glue and the glue overflows out of the glue groove, so that a shape with liquid surface tension is formed on the surface of a female seat; C, ultraviolet curing, wherein the female seattreated in the previous step is placed into a UV treatment chamber, and the optimal UV brightness and baking temperature are adjusted; and D, packaging, wherein the female seat treated in the previousstep is taken out of the UV chamber and packaged. According to the method, the sealing rubber strip is directly generated by means of directly dispensing the glue on the surface of the female seat, the problem that in the prior art, mounting is difficult is solved, and the sealing effect is good.

[0002] With the change of consumer demand, most of the smart devices on sale now have a certain waterproof function. The improvement of the waterproof ability of smart devices depends on the breakthrough of the waterproof ability of each external interface. The female socket is a main external interface. Refer to figure 1 , the waterproof function is set in the soft material in the contact area with the mobile phone shell, such as rubber, silica gel, plastic, etc., and the base body is also provided with grooves for accommodating the roots of these soft materials, in order to obtain a better Waterproof effect, these grooves are getting thinner and thinner, and even the width has reached the micron level. The reason is that water droplets have surface tension. For thinner gaps, water droplets are less likely to penetrate. At the same time, the finer the assembly accuracy The higher the value, the better the direct impact of water protection. In contrast to the design, most of the current industrial automation equipment can only achieve millimeter-level execution accuracy at most, and it is difficult to install. Use millimeter-level industrial equipment to assemble components with a design accuracy of microns It will cause the rate of defective products to soar and bring a lot of material waste. How to make a waterproof type-c female socket with better waterproof performance and higher yield rate has always troubled practitioners
