Description

Technical Field

[0001] This application relates to the field of electronic manufacturing equipment technology, and more specifically, to a universal clamping and transfer device for multi-specification PCBA boards. Background Technology

[0002] PCBA boards are carriers of electronic components. Through etching technology, conductive paths and component pads are formed on an insulating substrate. Electronic components such as resistors, capacitors, and integrated circuits perform specific functions on the PCB, thus forming a complete circuit.

[0003] PCBA boards have precision components such as resistors, capacitors, and IC chips soldered on their surface. The substrate has low hardness and is easy to bend. When handled manually, the oil, static electricity, or slight impact from fingers can cause components to fall off or the pins to deform. Clamping and transfer devices are usually used to ensure production efficiency and product quality.

[0004] However, existing clamping devices are inadequate when dealing with certain types of circuit boards, which are either too long or have unequal weights at both ends. When using conventional clamping methods, these circuit boards are prone to tilting or even falling during the clamping process. If this happens, it will not only affect the normal production process and reduce production efficiency, but may also damage the circuit board.

[0005] In view of this, we propose a universal clamping and transfer device for multi-specification PCBA boards. Summary of the Invention

[0008] The workbench has two support frames fixed to its top, and a placement platform fixed to the side wall of each support frame for placing circuit boards. A clamping mechanism is slidably mounted on the top of the workbench. A pressing mechanism is located at the bottom of the clamping mechanism. A seasoning mechanism is located within the support frames for adjusting misaligned circuit boards. The clamping mechanism includes a slidably mounted drive clamping plate that slides up and down under external force. Two clamping heads are slidably connected to the bottom drive shaft of the drive clamping plate for clamping the circuit boards. The pressing mechanism is located inside the clamping heads and includes a slidably mounted pressure plate that slides up and down under external force to press down the edges of the clamped circuit boards.

[0009] As an optional solution to the technical solution of this application, the clamping mechanism further includes a movable groove and a storage groove on the clamping head. A guide plate is slidably connected in the movable groove. The guide plate is fixedly connected to the pressure plate. A counterweight is fixedly connected to the bottom of the guide plate. The counterweight is shaped to match the storage groove. The storage groove is used to store the counterweight after it is closed.

[0011] As an optional solution to the technical solution of this application, a mounting plate is fixedly connected to one side of the fastener, and a baffle plate is rotatably connected to the side wall of the mounting plate, wherein the baffle plate is set near the side of the limiting groove.

[0012] As an optional solution to the technical solution of this application, a metal patch is fixedly connected to the top of the support frame, and a magnetic block is fixedly connected to the end of the shielding plate, wherein the metal patch and the magnetic block are attracted to each other.

[0014] As an optional solution to the technical solution of this application, the clamping mechanism further includes sliding members installed on both sides of the worktable. The sliding members are slidably arranged on both sides of the worktable. A support frame is fixedly connected to the top of the sliding members.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] (1) This application uses a clamping mechanism, which, in conjunction with the downward pressing effect of the pressure plate, can improve the stability of the circuit board after clamping.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-5This application discloses a universal clamping and transferring device for multi-specification PCBA boards, comprising a worktable 1, a clamping mechanism 2, a pressing mechanism 3, and a adjusting mechanism 4. Two support frames 11 are fixedly connected to the top of the worktable 1, and a placement platform 12 is fixedly connected to the side wall of each support frame 11 for placing a circuit board 100. A slidable arrangement is made on the top of the worktable 1; a clamping mechanism 2 is located at the bottom of the worktable 1; and a placement platform 12 is located within the support frames 11 for adjusting any misaligned circuit boards 100. The clamping mechanism 2 includes a slidably arranged drive clamping plate 21, which slides up and down under external force. Two clamping heads 22 are slidably connected to the bottom drive shaft of the drive clamping plate 21 for clamping the circuit board 100. The pressing mechanism 3 is located inside the clamping heads 22 and includes a slidably arranged pressure plate 31, which slides up and down under external force to press down on the edges of the clamped circuit board 100. The clamping mechanism 3 also includes a movable groove 221 and a storage groove 222 on the clamping head 22. A guide plate 32 is slidably connected in the movable groove 221. The guide plate 32 is fixedly connected to the pressure plate 31. A counterweight 33 is fixedly connected to the bottom of the guide plate 32. The counterweight 33 is shaped to match the storage groove 222. The storage groove 222 is used to store the counterweight 33 after it is closed. A rubber pad is provided at the bottom of the pressure plate 31. The clamping mechanism 2 also includes sliding parts 23 installed on both sides of the worktable 1. The sliding parts 23 are slidably set on both sides of the worktable 1. A support frame 24 is fixedly connected to the top of the sliding parts 23. An electric push rod A25 is installed in the middle of the support frame 24. The electric push rod A25 is slidably set on the support frame 24. The output shaft of the electric push rod A25 is fixedly connected to the drive clamping plate 21. A control panel 13 is installed on one side of the worktable 1. Multiple support feet 14 are fixedly connected to the bottom of the worktable 1.After the workbench 1 is installed, the support feet 14 ensure its stability. The control panel 13 is used to operate the various mechanisms. When the circuit board 100 needs to be clamped, the sliding member 23 can be controlled to slide on the workbench 1 until the drive clamping plate 21 is moved to the appropriate position. Then, the electric push rod A25 switch is activated, causing the drive clamping plate 21 to extend downwards as a whole. The multiple clamping heads 22 then pass over the circuit board 100 and gradually come into contact with the placement table 12. This allows the downward-protruding counterweight block 33 to contact the placement table 12 first and, under the support force, gradually slide into the clamping head 22. At the same time, the pressure plate 31 can slide upwards, forming a gap between the pressure plate 31 and the clamping head 22. After the circuit board 100 is clamped into the gap, it is then... Multiple clamping heads 22 are brought close together for clamping, while the drive clamping plate 21 can move upwards again. Under the weight of the counterweight 33, the pressure plate 31 is pulled downwards and comes into contact with the clamped circuit board 100. The rubber pads on the pressure plate 31 allow direct contact with the circuit board 100. This step, combined with the downward pressing effect of the pressure plate 31, improves the stability of the circuit board 100 after clamping. This solves the problem of some circuit board 100 models tilting or even falling during clamping due to their length or uneven weight at both ends. It achieves a stable transfer effect for the circuit board 100, and the rubber pads on the pressure plate 31 further enhance the stability during clamping and transfer.

[0026] Reference Figures 1-5 The seasoning mechanism 4 includes two support members 41 fixed inside the support frame 11. An electric actuator B42 is installed inside each support member 41. A fixing member 43 is fixedly connected to the output shaft of the electric actuator B42. A limiting groove 111 is formed at the top of the support frame 11. The fixing member 43 is slidably connected to the limiting groove 111. Push plates 44 are fixedly connected to the side walls of the two limiting grooves 111, and the push plates 44 are flush with the placement platform 12. When the circuit board 100 shifts on the placement platform 12, the electric actuator B42 is activated, and its output shaft pushes the fixing member 43 to slide along the limiting groove 111. The fixing member 43 then drives... The push plate 44 moves, and by using the flush setting of the push plate 44 with the placement stage 12, it pushes the offset circuit board 100 to adjust its position on the placement stage 12. After the adjustment is completed, the electric push rod B42 can be driven again to reset the push plate 44 back to the correct position. The flush design of the push plate 44 with the placement stage 12 allows the push plate 44 to accurately contact the circuit board 100 and push it to move, thereby realizing universal adjustment for circuit boards 100 of different specifications, ensuring the accuracy of subsequent clamping and transfer operations, and avoiding clamping failure or damage to the circuit board 100 due to the offset of the circuit board 100.

[0027] Reference Figures 1-5A mounting plate 45 is fixedly connected to one side of the fixing member 43. A baffle plate 46 is rotatably connected to the side wall of the mounting plate 45. The baffle plate 46 is located near the limiting groove 111. A metal patch 112 is fixedly connected to the top of the support frame 11. A magnetic block 47 is fixedly connected to the end of the baffle plate 46. The metal patch 112 and the magnetic block 47 are attracted to each other. When the fixing member 43 moves, the mounting plate 45 fixed to one side of the fixing member 43 will also move accordingly, so that the unfolded baffle plate 46 can continuously block the limiting groove 111. Subsequently, the baffle plate 46 can be pushed upwards to open and the electric actuator B42 inside the support frame 11 can be inspected. This step, together with the baffle plate 46, can prevent external impurities from being transferred into the support frame 11 through the limiting groove 111 and directly contacting the electric actuator B42, thus improving the stability of the electric actuator B42 during use. The attraction between the magnet 47 and the metal patch 112 can improve the stability of the baffle plate 46 when the fixing part 43 is moving.

[0028] In summary, the universal clamping and transfer device for multi-specification PCBA boards disclosed in this application, when in use, involves installing the workbench 1, with the support legs 14 ensuring its stability. The control panel 13 controls the operation of each mechanism. When clamping the circuit board 100, the sliding member 23 can be controlled to slide on the workbench 1 until the drive clamping plate 21 is transferred to a suitable position. Then, the electric push rod A25 switch is activated, causing the drive clamping plate 21 to extend downwards. The multiple clamping heads 22 then pass over the circuit board 100 and gradually contact the placement table 12. This allows the downward-protruding counterweight 33 to contact the placement table 12 first and, under the support force, gradually slide into the clamping head 22. Simultaneously, the pressure plate 31 slides upwards, creating a gap between the pressure plate 31 and the clamping head 22. After the circuit board 100 is inserted into the gap, it is clamped by the proximity of the multiple clamping heads 22. The entire assembly can be moved upwards again, and under the weight of the counterweight 33, the pressure plate 31 is pulled downwards and comes into contact with the locked circuit board 100. Through the rubber pad on the pressure plate 31, it can directly contact the circuit board 100. When the circuit board 100 is placed on the placement platform 12 and shifts, the electric push rod B42 is activated. Its output shaft pushes the fixing member 43 to slide along the limiting groove 111. The fixing member 43 drives the push plate 44 to move. By using the setting of the push plate 44 being flush with the placement platform 12, the shifted circuit board 100 is pushed and its position on the placement platform 12 is adjusted. After the adjustment is completed, the electric push rod B42 can be driven again to reset the push plate 44 back to the correct position. When the fixing member 43 moves, the mounting plate 45 fixed to one side of the fixing member 43 will also move, so that the unfolded cover plate 46 can continuously cover the limiting groove 111. The cover plate 46 can also be pushed upwards to open it and the electric push rod B42 inside the support frame 11 can be inspected.
