Antistatic collection box for circuit board

Abstract

The invention discloses an antistatic collection box for a circuit board, which comprises a collection box body and a track type rack arranged in the collection box body. The collection box body comprises a bottom plate, a cover plate and a strut for fixedly connecting the bottom plate and the cover plate; and the track type rack encircles an accommodating cavity for placing the circuit board. The antistatic collection box is structurally characterized by also comprising a space partitioning device for partitioning the accommodating cavity into two space areas; and the space partitioning device comprises a rod body, a spring and a positioning clamping pin; and the positioning clamping pin is fixed on the upper part of the rod body, the top end of the spring is fixed on the lower part of the rod body, and the bottom end of the spring can stretch freely. The antistatic collection box has the advantages of fully utilizing the space in the box by inserting two circuit boards into the same groove layer of the track type rack at the same time, avoiding mutual collision between the two circuit boards in the same groove during inserting and transporting, preventing sensitive components on the circuit board from being damaged, and meanwhile shortening the adjustment time and the complex adjustment process.

Description

Technical field: [0001] The invention belongs to the field of article transfer devices, and in particular relates to an antistatic collection box for circuit boards. Background technique: [0002] A circuit board is a structural element formed of insulating materials supplemented by conductor wiring. When the final product is made, integrated circuits, transistors, diodes, passive components (such as resistors, capacitors, connectors, etc.) and various other electronic components will be installed on it. Due to the delicate electronic components mounted on the circuit board, it requires a special transport turnover device during the transfer process. [0003] ZL200620102407.6 discloses a fast-adjustable circuit board anti-static collecting rack, the main improvement of which is to change one of the original two fixed side panels into a movable side panel that can be slid on the slide rail, so that when encountering When it comes to circuit boards of different widths, the d...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent can only solve the problem that the collection rack can only be used for a fixed-width circuit board, but the applicant has not studied the storage problem of circuit boards of different lengths, that is, the circuit boards have different widths, and their relative lengths are different. There is also a problem of inconsistency in the direction, but if the above-mentioned thinking of the applicant is followed, the problem of changing the width and length of the circuit board cannot be solved at the same time

[0005] Although the antistatic collecting frame disclosed in the above-mentioned patent can adapt to circuit boards of different widths, when the circuit board is small, the above-mentioned collecting frame can only change the width but cannot change the length, which will cause the following problems: 1. When a layer of grooves Putting a circuit board inside will cause a waste of space in the box; 2. If two circuit boards are placed in the groove of the same layer, it will cause collision between the two circuit boards, which will make the electric current on the surface of the circuit board Components are damaged, so that the circuit board cannot be used; 3. When inserting two circuit boards into the same groove, the operator will insert the circuit from the same direction or two directions because the space between the same groove is connected. board, in order to avoid damage to the circuit board when inserted, it will increase the operating time, which is not suitable for the speed requirements of industrial production, and will cause delays to other process steps on the same production line, and in severe cases will cause the collapse of the production line

[0006] In addition, when the existing anti-static collection boxes are stacked on each other, because the cover plate and the bottom plate are relatively smooth, they are stacked on top of each other only by gravity, and there is no locking mechanism between them, so they are easy to fall due to vibration and collision, causing losses.
