Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a simple PIN mounting device. Background Technology

[0002] Pins are used to position and install multilayer boards together. Most circuit boards are made by thermally pressing layers of copper-clad laminates. During the lamination process, pins are used to position the layers. The pins need to be pressed into positioning holes during lamination. The pins are usually cylindrical iron posts. The process of adding pins can be understood as drilling holes in the circuit board and inserting pins so that the pins can play a role in positioning and fixing in subsequent processing.

[0003] A search revealed a Chinese patent publication number CN216362386U, which discloses a simple pin-attaching device. The device includes a slide rail with sliding mechanisms slidably mounted at both ends. Each sliding mechanism includes a sliding seat, a fixed plate on the sliding seat, and a threaded rod on the fixed plate. The threaded rod is threadedly connected to the fixed plate, and a rotating ring is located at the front end of the threaded rod. A groove is formed at the front end of the slide rail corresponding to the threaded rod. A support seat is located at the upper end of the sliding seat, and a driving mechanism is threaded through the support seat. A pin fixing seat is located at the lower end of the driving mechanism. A pressure plate is detachably mounted on the upper surface of the sliding seat, and an operating groove is formed on the pressure plate.

[0004] However, in actual use, it was found that because the pins need to be installed on the pin holders, the circuit board needs to be placed on the support plate, and the pinning operation needs to be performed on the circuit board, the rotating ring also needs to be tightened or loosened at the same time. However, when the operator repeats this operation for a long time, the operator may forget to fix the rotating ring, which will cause the sliding seat to slip during the pinning process, reducing the accuracy and efficiency of the operation. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when workers repeat the operation for a long time, they may forget to fix the rotating ring, which will cause the sliding seat to slip during the pin-attaching process, reducing the accuracy and efficiency of the operation. Therefore, a simple pin-attaching device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A simple pin-attaching device includes a support rod and a worktable slidably connected to the support rod. The worktable has a guide groove, and an airbag is disposed within the guide groove. A limiting groove is formed on the outer wall of the support rod, and the outer surface of the airbag can fit against the inner wall of the limiting groove. A locking bolt is rotatably connected to the worktable, wherein the contact end of the locking bolt abuts against the outer wall of the support rod, and the locking bolt cooperates with the airbag. An air supply assembly is used to inflate the airbag.

[0008] To facilitate the supply of gas to the airbag, preferably, the gas supply assembly includes a booster rod, a booster groove is provided on the worktable, a sealing plug is slidably connected in the booster groove and the sealing plug is in contact with the inner wall of the booster groove, the booster rod is fixedly connected to the sealing plug, and the booster groove is connected to the airbag through a pipe.

[0009] To facilitate the reset of the sealing plug, a reset spring is further provided in the pressure-boosting groove, with both ends of the reset spring fixedly connected to the sealing plug and the pressure-boosting groove, respectively.

[0010] To facilitate the storage of the limiting plate, preferably, the top of the booster rod is fixedly connected to the limiting plate, and a fixing groove is provided on the worktable, so that the limiting plate can fit against the inner wall of the fixing groove.

[0011] To improve the stability of the pressure plate, preferably, the worktable is provided with a placement groove, the pressure plate is detachably connected in the placement groove, the pressure plate is provided with a slot, and the limiting plate is provided with an extension plate. When the limiting plate is in contact with the inner wall of the fixing groove, the extension plate is engaged in the slot.

[0012] To facilitate the storage of PIN pins, preferably, a collection box is detachably connected to the placement slot, and the collection box is located below the pressure plate.

[0013] To improve the stability of the workbench on the support rod, preferably, a guide groove is provided on the outer wall of the support rod, and the contact end of the locking bolt can abut against the inner wall of the guide groove.

[0014] To facilitate the pressing operation of the PIN pin, preferably, a support plate is fixedly connected to the top of the workbench, and a telescopic cylinder is fixedly connected to the support plate. The output end of the telescopic cylinder is provided with a PIN pin fixing seat.

[0015] Compared with the prior art, the present invention provides a simple PIN mounting device, which has the following advantages:

[0016] 1. This simple pin-attaching device allows the circuit board to be placed on the limiting plate when the operator forgets to use the locking bolt to limit the position of the worktable. The weight of the circuit board will automatically apply pressure to the booster rod, allowing the outside of the airbag to fit against the inner wall of the limiting groove. When the operator repeats the pin-attaching operation for a long time, the inflated airbag will assist the locking bolt in limiting the position of the worktable, reducing the slippage of the worktable during the pin-attaching process, thereby improving the accuracy and efficiency of the operation.

[0017] 2. This simple PIN mounting device supports the circuit board through a pressure plate. When the limiting plate descends, the extension plate can be locked in the slot, thereby limiting the position of the pressure plate and preventing shaking during the PIN mounting process. The PIN pins can be collected in the collection box for use during operation.

[0018] All parts of this device not described herein are the same as or can be implemented using existing technology. In this utility model, when the operator forgets to use the locking bolt to limit the worktable, the circuit board placed on the worktable will automatically press the limiting plate. At this time, the airbag inflates, and the inflated airbag will assist the locking bolt in limiting the position of the worktable, reducing the phenomenon of the worktable sliding during the pin loading process, thereby improving the accuracy and efficiency of the operation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-4 A simple PIN mounting device includes a support rod 1, and further includes: a worktable 4 slidably connected to the support rod 1, wherein the worktable 4 has a guide groove 13, an airbag 14 is disposed in the guide groove 13, a limiting groove 3 is provided on the outer wall of the support rod 1, and the outside of the airbag 14 can fit against the inner wall of the limiting groove 3; a locking bolt 18 rotatably connected to the worktable 4, wherein the contact end of the locking bolt 18 can abut against the outer wall of the support rod 1, and the locking bolt 18 cooperates with the airbag 14; and an air supply assembly for inflating the airbag 14.

[0028] It should be explained that a support plate 15 is fixedly connected to the top of the workbench 4, and a telescopic cylinder 16 is fixedly connected to the support plate 15. A PIN pin fixing seat 17 is provided at the output end of the telescopic cylinder 16.

[0029] When the position of the worktable 4 needs to be adjusted, the worktable 4 can be slid on the support rod 1. A guide groove 2 is provided on the outer wall of the support rod 1. The contact end of the locking bolt 18 can abut against the inner wall of the guide groove 2. At this time, the locking bolt 18 is rotated clockwise so that the contact end of the locking bolt 18 can abut against the guide groove 2. At the same time, the locking bolt 18 is rotated counterclockwise so that the contact end of the locking bolt 18 can no longer abut against the guide groove 2. This is the prior art.

[0030] Furthermore, the air supply assembly includes a booster rod 10, a booster groove 9 is provided on the worktable 4, a sealing plug is slidably connected inside the booster groove 9 and the sealing plug is in contact with the inner wall of the booster groove 9, the booster rod 10 is fixedly connected to the sealing plug, and the booster groove 9 is connected to the airbag 14 through a pipe. A return spring 12 is provided inside the booster groove 9, and the two ends of the return spring 12 are fixedly connected to the sealing plug and the booster groove 9 respectively.

[0031] By pressing the booster rod 10, the sealing plug moves downward along the inner wall of the booster groove 9. During this process, the return spring 12 is compressed, and the sealing plug delivers the air in the booster groove 9 to the airbag 14 through the pipe. At this time, the airbag 14 expands, extending to the outside of the support rod 1, and the outside of the airbag 14 fits against the inner wall of the limiting groove 3, so that it can limit the position of the worktable 4.

[0032] Here, during the pin insertion process, the PIN pin holder 17, which moves up and down, also applies pressure to the circuit board, thereby pressing the booster rod 10 in conjunction with the circuit board.

[0033] When the pressurizing lever 10 is stopped, the expansion of the return spring 12 will cause the sealing plug to move upward along the inner wall of the pressurizing groove 9, at which point the gas in the airbag 14 will be re-transported into the pressurizing groove 9.

[0034] Furthermore, a limiting plate 11 is fixedly connected to the top of the booster rod 10, and a fixing groove 19 is provided on the worktable 4, so that the limiting plate 11 can fit against the inner wall of the fixing groove 19.

[0035] Furthermore, when the operator forgets to use the locking bolt 18 to limit the position of the worktable 4, the circuit board is placed on the limiting plate 11. Due to the weight of the circuit board, it will automatically apply pressure to the booster rod 10. At this time, the outside of the airbag 14 can fit against the inner wall of the limiting groove 3. When the operator repeats the pin-attaching operation for a long time, the inflated airbag 14 will assist the locking bolt 18 in limiting the position of the worktable 4, reducing the phenomenon of the worktable 4 sliding during the pin-attaching process, thereby improving the accuracy and efficiency of the operation.

[0036] In addition, a placement slot 5 is provided on the workbench 4, and a pressure plate 7 is detachably connected in the placement slot 5. A slot 8 is provided on the pressure plate 7, and an extension plate is provided on the limiting plate 11. When the limiting plate 11 is in contact with the inner wall of the fixing slot 19, the extension plate is engaged in the slot 8. A collection box 6 is detachably connected in the placement slot 5, and the collection box 6 is located below the pressure plate 7.

[0037] The pressure plate 7 can support the circuit board. When the limiting plate 11 descends, the extension plate can be locked in the slot 8, thereby limiting the position of the pressure plate 7 and preventing shaking during the pin insertion process. The collection box 6 can collect the pins for use during operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
