Description

Technical Field

[0001] This utility model relates to the field of pick and place machine technology, specifically a pick and place machine that facilitates the fixing and disassembly of PCB boards. Background Technology

[0002] Pick and place machine: Also known as "placement machine" or "surface mount system", it is a device installed after the dispensing machine or screen printer in the production line. It is a device that accurately places surface mount components onto the PCB pads by moving the placement head. It is divided into manual and fully automatic types.

[0003] Currently, existing manual pick-and-place machines on the market require the PCB board to be clamped and fixed during operation to prevent displacement during placement. However, the clamping mechanism on existing pick-and-place machines is cumbersome to operate when fixing and removing the PCB board. Utility Model Content

[0004] The purpose of this invention is to provide a pick-and-place machine that facilitates the fixing and disassembly of PCB boards, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pick-and-place machine for easy fixing and removing PCB boards, including

[0007] A platform is fixedly installed at the top center of the platform, and a clamping mechanism is provided at the center of the platform.

[0008] A centering mechanism perpendicular to the clamping mechanism is provided in the middle of the mounting stage, and a driving mechanism is provided inside the platform. The driving mechanism cooperates with the clamping mechanism.

[0009] Preferably, the clamping mechanism includes a guide groove, a guide groove is formed in the middle of the mounting table, a guide rod is fixedly installed in the middle of the guide groove, movable blocks are movably sleeved at both ends of the guide rod, and a clamping block is fixedly installed at the top of the movable block.

[0010] Preferably, the centering mechanism includes a guide frame, with guide frames provided on both sides of the upper end of the patch table and near the center of the guide groove. A clamping plate is movably installed on the front of the guide frame, and movable rods that are movably sleeved with the guide frame are provided on both sides of the back of the clamping plate. A spring is provided between the clamping plate and the guide frame outside the movable rods.

[0011] Preferably, the drive mechanism includes a gear, which is movably mounted in the middle of the inner side of the platform, and a rack meshes with one side of the gear. A pull rod is movably mounted on one end of the rack via a bearing.

[0012] Preferably, the platform has a threaded groove on the side near the pull rod, and the pull rod has an external thread on the side near the rack.

[0013] Preferably, the driving mechanism further includes a second gear, which is provided at the top of the first gear, and a second rack is meshed on both sides of the second gear. A fixing block is provided at one of the opposite ends of the second rack, which is fixedly connected to the movable block. Guide bars matching the second rack are provided on both sides of the patching stage near the second gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This is a pick-and-place machine that facilitates the fixing and disassembly of PCB boards. When clamping, pulling the lever causes rack one to move horizontally. Rack one drives gear one to rotate, and gear one drives gear two to rotate. When gear two rotates, it drives rack two on both sides to move towards each other. Rack two drives movable block to move synchronously through fixed block. Movable block drives clamping block to move to both sides of PCB board. Then, rotating the lever connects the external thread to the threaded groove, so that the clamping block is clamped on the outside of PCB board. When disassembling later, flipping the threaded groove and external thread can quickly release the clamping block, making fixing and disassembly more convenient.

[0016] 2. This is a pick-and-place machine that facilitates the fixing and removal of PCB boards. When fixing the PCB board, the PCB board is pressed down from the middle of the placement table. When pressed down, the clamps on both sides of the PCB board will open. Since there are springs on the back of the clamps that are movably connected to the guide frame, the elastic force of the springs can control the PCB board to automatically center itself. Then, the two clamps are controlled to move towards each other and clamp the other two sides of the PCB board. In this way, the PCB board can be automatically centered during installation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution:

[0025] A pick-and-place machine for easy fixing and disassembly of PCB boards includes a platform 1, a placement table 2 fixedly installed at the top center of the platform 1, a clamping mechanism provided at the center of the placement table 2, the clamping mechanism including a guide groove 3, the guide groove 3 being opened at the center of the placement table 2, a guide rod 4 fixedly installed at the center of the guide groove 3, movable blocks 5 being movably sleeved at both ends of the guide rod 4, a clamping block 6 being fixedly installed at the top of the movable block 5, a centering mechanism perpendicular to the clamping mechanism being provided at the center of the placement table 2, the centering mechanism including a guide frame 7, guide frames 7 being provided on both sides at the upper end of the placement table 2 and near the center of the guide groove 3, a clamping plate 8 being movably installed on the front of the guide frame 7, movable rods 9 being movably sleeved on both sides of the back of the clamping plate 8, and a spring 10 being provided between the clamping plate 8 and the guide frame 7 outside the movable rods 9;

[0026] In this embodiment, when fixing the PCB board, the PCB board is pressed down from the middle of the mounting table 2. When pressed down, the clamping plates 8 will be spread open on both sides of the PCB board. Since the back of the clamping plate 8 is provided with a spring 10 that is movably connected to the guide frame 7, the elastic force of the spring 10 can control the PCB board to automatically center. Then, the two clamping blocks 6 are controlled to move towards each other and clamp the other two sides of the PCB board. In this way, the PCB board can be automatically centered during installation.

[0027] like Figure 2 , Figure 3 and Figure 5As shown, a drive mechanism is provided inside the platform 1. The drive mechanism includes a gear 11. The gear 11 is movably installed in the middle of the inner side of the platform 1. A rack 12 meshes with one side of the gear 11. A pull rod 13 is movably installed at one end of the rack 12 through a bearing. The drive mechanism and the clamping mechanism cooperate with each other. A threaded groove 14 is provided on the side of the platform 1 near the pull rod 13. An external thread 15 is provided on the outside of the side of the pull rod 13 near the rack 12. The drive mechanism also includes a gear 2 16. The gear 2 16 is provided at the top of the gear 11. A rack 2 17 meshes with both sides of the gear 2 16. A fixing block 18 is provided at the opposite end of the rack 2 17 and is fixedly connected to the movable block 5. Guide bars 19 that match the rack 2 17 are provided on both sides of the mounting table 2 near the gear 2 16.

[0028] In this embodiment, when clamping, the pull rod 13 is pulled, which drives the rack 12 to move horizontally. The rack 12 drives the gear 11 to rotate, and the gear 11 drives the gear 2 16 to rotate. When the gear 2 16 rotates, it drives the racks 2 17 on both sides to move towards each other. The racks 2 17 drive the movable block 5 to move synchronously through the fixed block 18. The movable block 5 drives the clamping block 6 to move to both sides of the PCB board. Then, the pull rod 13 is rotated, and the external thread 15 is threadedly connected to the threaded groove 14, so that the clamping block 6 is clamped on the outside of the PCB board. When disassembling later, the clamping block 6 can be quickly released by flipping the threaded groove 14 and the external thread 15, which makes fixing and disassembly more convenient.

[0029] Working principle: When fixing the PCB board, the PCB board is pressed down from the middle of the mounting table 2. When pressed down, the clamping plates 8 on both sides of the PCB board will be opened. Since the back of the clamping plate 8 is equipped with a spring 10 that is movably connected to the guide frame 7, the elastic force of the spring 10 can control the PCB board to automatically center. Then, pull the lever 13. The lever 13 drives the rack 12 to move horizontally. The rack 12 drives the gear 11 to rotate. The gear 11 drives the gear 2 16 to rotate. When the gear 2 16 rotates, it drives the racks 2 17 on both sides to move towards each other. The racks 2 17 drive the movable block 5 to move synchronously through the fixed block 18. The movable block 5 drives the clamping block 6 to move to both sides of the PCB board. Then, rotate the lever 13 and connect it to the threaded groove 14 through the external thread 15, so that the clamping block 6 is clamped on the outside of the PCB board.
