[0002] At present, the market demand for PCB circuit boards is increasing. Among them, a large number of PCB circuit boards only need to insert 1 to 2 plug-in components on the circuit board during production and then weld and fix them. For the production of such PCB circuit boards with fewer plug-in components, if wave soldering is still used, the cost is too high. In the actual production process, the plug-in components of such PCB circuit boards are mostly manually inserted and welded.

[0003] During manual operation, usually one component is inserted and then welded, that is, one component is inserted and welded and fixed one by one, which is time-consuming, laborious, with low work efficiency. Moreover, with multiple batches of welding, the welding specifications are not easy to be unified and are prone to errors. Summary of the Utility Model

Welding interfaces penetrating through the front and back surfaces of the working plate are arranged in the placement groove, and the welding interfaces are aligned with the insertion positions of the plug-in components on the circuit board;

[0008] One side of the cover plate is connected to the working plate through a hinge. A first magnet is arranged on the other side of the cover plate opposite to the hinge, and a second magnet cooperating with the first magnet is arranged on the working plate;

[0009] An elastic mechanism is arranged on the cover plate to press and fix the plug-in components on the circuit board in the placement groove when the cover plate is closed.

[0010] As a further improved technical scheme of the utility model, the elastic mechanism includes a pressing plate, a spring, a spring cylinder, a connecting rod, and a limiting block. The spring cylinder is fixedly arranged on the surface of the cover plate opposite to the placement groove. The limiting block is arranged in the spring cylinder and fixedly connected to one end of the connecting rod. The other end of the connecting rod penetrates through the cover plate and is fixedly connected to the pressing plate. One end of the spring presses against the spring cylinder, and the other end of the spring presses against the limiting block.

[0011] As a further improved technical solution of the present utility model, the support plates on both sides of the connecting plate have different heights, so that when the working plate is lapped on the top of the support plates, it is inclined with respect to the bottom plate.

[0012] As a further improved technical solution of the present utility model, the quick-release structure includes a positioning pin and pin holes provided on the connecting plate and the working plate.

The working plate 6 is lapped on the top of the support plate 2;

[0022] On the front surface of the working plate 6, there is a placement groove 7 for accommodating a circuit board. In the placement groove 7, there are welding interfaces 8 penetrating through the front and back surfaces of the working plate 6, and the welding interfaces 8 are aligned with the insertion positions of the plug-in components on the circuit board;

[0023] One side of the cover plate 5 is connected to the working plate 6 through a hinge (not shown, the hinge is located at Figure 1 the connection between the lower side of the cover plate 5 and the working plate 6). On the other side of the cover plate 5 opposite to the hinge, there is a first magnet (the first magnet is located at Figure 1 the upper side of the cover plate 5, and is arranged in alignment with the second magnet 4 on the working plate 6). On the working plate 6, there is a second magnet 4 that cooperates with the first magnet;

[0024] On the cover plate 5, there is an elastic mechanism 9 to press and fix the plug-in components on the circuit board in the placement groove 7 when the cover plate 5 is closed.

[0025] In this embodiment, there are two connecting plates 3, which are respectively located on the left and right sides of the working plate 6 and are used for connecting and fixing the working plate 6.

[0026] There are four support plates 2. Two support plates 2 are located in front of the connecting plate 3, and two support plates 2 are located behind the connecting plate 3. The tops of the support plates 2 are lapped on the bottom surface of the working plate 6 and are used to support the working plate 6.

[0027] The heights of the two support plates 2 located in front of the connecting plate 3 are less than the heights of the two support plates 2 located behind the connecting plate 3, so that when the working plate 6 is lapped on the top of the support plates 2, it is inclined with respect to the bottom plate 1. The inclined working plate 6 faces the operator, facilitating the operator to perform plug-in and welding operations.

[0028] Furthermore, the elastic mechanism 9 includes a pressing plate 91, a spring 92, a spring cylinder 93, a connecting rod 94, and a limiting block 95.

One end of the spring 92 presses against the spring cylinder 93, and the other end of the spring 92 presses against the limiting block 95.

[0029] When the cover plate 5 is closed, the spring 92 is compressed, and the pressing plate 91 presses and fixes the plug-in components on the circuit board in the placement groove 7.

[0030] When the area of a single pressing plate 91 is relatively large, multiple sets of springs 92, spring cylinders 93, connecting rods 94, and limit blocks 95 can be provided to cooperate with it.

[0031] Furthermore, the quick-release structure includes a positioning pin and pin holes 10 provided on the connecting plate 3 and the working plate 6.

[0032] Furthermore, the shape and size of the placement groove 7 match the shape and size of the circuit board.

[0033] The usage process of the present utility model is as follows:

[0034] The operator inserts the positioning pin into the pin hole 10 and fixes the working plate 6 with its front side (the side with the placement groove 7) facing up on the connecting plate 3. Open the cover plate 5, place the circuit board into the placement groove 7, and insert all the plug-in components to be welded at the corresponding positions on the circuit board. After completing the plug-in, close the cover plate 5, and the cover plate 5 is magnetically attracted to the working plate 6 by the magnetic forces of the first magnet and the second magnet 4.

[0035] The operator pulls out the positioning pin, flips the working plate 6 and fixes it on the connecting plate 3 again, and completes the welding and fixing of all the plug-in components through the welding interfaces 8 on the back. Finally, open the cover plate 5 and take out the circuit board.

[0036] Compared with the prior art, the technical effect of the present utility model is as follows:

[0037] The structure of the present utility model is simple and the function is practical. First, insert all the plug-in components on the circuit board, then close the cover plate 5, and after flipping the working plate 6, weld and fix all the plug-in components on the circuit board together, which saves time and effort, helps improve work efficiency, and it is easier to unify the specifications for welding in the same batch, which helps improve the qualified rate.

[0038] By replacing different working plates 6 (the placement grooves 7 of different working plates 6 match the corresponding specification circuit boards, and the welding interfaces 8 match the insertion positions of the plug-in components on the circuit board), it can be used to assist the manual welding operation of plug-in components for different specification PCB circuit boards.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
