Description

Technical Field

[0001] This utility model provides a PCB board fixing device for a plug-in machine, belonging to the technical field of plug-in machine equipment. Background Technology

[0002] With the rapid development of the electronics manufacturing industry, surface mount technology (SMT) is increasingly widely used in electronic product manufacturing. As a key piece of equipment on the SMT production line, the performance and precision of the insertion machine directly affect product quality and production efficiency. During the operation of the insertion machine, PCB board fixation is a crucial step, affecting not only the precision and consistency of the insertion but also the stability of the equipment and the efficiency of the production line.

[0003] Traditionally, PCB boards are secured using clamping devices such as jigs. These jigs apply force to the PCB board, thus fixing it to the worktable. However, this method suffers from difficulty in controlling the clamping force. Excessive clamping force can easily bend or even damage the PCB board, affecting component insertion accuracy. Furthermore, it's challenging to maintain uniform clamping force, increasing the risk of unstable PCB board fixation and consequently impacting positioning accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that when using a plug-in machine to fix PCB boards, traditional clamping and positioning methods can easily affect the positioning accuracy of the PCB boards.

[0005] To solve the above problems, the proposed technical solution is as follows: a PCB board fixing device for a plug-in machine, including a worktable, a support frame fixedly connected to the worktable, a plug-in device mounted on the support frame, and a PCB board placed on the worktable below the plug-in device, the PCB board having four mounting holes; further comprising:

[0006] The worktable has a groove, in which a positioning component slides up and down and is inserted into a mounting hole through the worktable; the fixing component is disposed on the inner wall of the support frame, and the positions of the fixing component and the positioning component correspond to each other.

[0007] The system includes a feeding frame, a feeding assembly, and an alignment assembly. A chute is provided inside the worktable, and the feeding assembly is located inside the chute. The feeding frame is slidably mounted on the worktable, and the feeding assembly is connected to the feeding frame. The alignment assembly includes a laser emitter and a laser receiver. The laser emitter is located on the positioning assembly, and the laser receiver is located on the fixing assembly, with the laser emitter and laser receiver corresponding to each other.

[0008] As an improvement, the positioning assembly includes a lifting plate and positioning rods. The lifting plate is slidably disposed in the groove, and the positioning rods are fixedly connected to the lifting plate. Four positioning rods are provided, and the four positioning rods are inserted into the mounting holes. A first electric telescopic rod is provided in the groove, and the working end of the first electric telescopic rod is fixedly connected to the lifting plate.

[0009] As an improvement, the fixing assembly includes a second electric telescopic rod and a limiting rod. Four second electric telescopic rods are provided, and the second electric telescopic rods are fixedly connected to the inner wall of the support frame. The limiting rod is fixedly connected to the working end of the second electric telescopic rod, and the position of the limiting rod corresponds to that of the positioning rod.

[0010] As an improvement, the width of the inner wall of the feed frame corresponds to the width of the PCB board, and a through hole is provided on the feed frame.

[0011] As an improvement, the feeding assembly includes a feeding electric push rod and a slider. The feeding electric push rod is located in the slide groove, and the slider is slidably disposed in the slide groove and fixedly connected to the working end of the feeding electric push rod. A guide groove is provided on the worktable, and the slider passes through the guide groove and is fixedly connected to the feeding frame.

[0012] As an improvement, a support frame is fixedly connected below the lifting plate, and the laser emitter is fixedly installed inside the support frame; a placement groove is opened inside the limiting rod, and a laser receiver corresponding to the laser emitter is fixedly installed inside the placement groove.

[0013] As an improvement, the positioning rod is a hollow tube, and the lifting plate has a through hole corresponding to the positioning rod.

[0014] As an improvement, the side wall of the workbench is provided with a controller that is connected to the laser receiver circuit, and the controller is also connected to the feeding electric push rod, the first electric telescopic rod, and the second electric telescopic rod.

[0015] The beneficial effects of this utility model are:

[0016] By setting up a laser emitter and a laser receiver, precise positioning of the PCB board can be achieved. The positioning component passes through the worktable and is inserted into the mounting hole. This application utilizes the mounting hole on the PCB board itself. By inserting the positioning component into the mounting hole, the PCB board is positioned once, ensuring that the horizontal movement of the PCB board is restricted. At the same time, the fixing component can perform secondary positioning of the PCB board and restrict its vertical movement. By fixing the PCB board through two limiting methods, the positioning accuracy is high compared with traditional clamping and fixing methods, and there is no problem of excessive clamping force leading to clamping instability or PCB board bending and deformation.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] according to Figure 1-5 As shown: This utility model provides a PCB board fixing device for a plug-in machine: including a workbench 1, a support frame 2 fixedly connected to the workbench 1, a plug-in device 3 mounted on the support frame 2, and a PCB board 7 placed on the workbench 1 below the plug-in device, the PCB board 7 having four mounting holes 17; also including:

[0025] The positioning component and the fixing component are provided. A groove 9 is provided in the worktable 1. The positioning component is slidably arranged in the groove 9 and is inserted into the mounting hole 17 through the worktable 1. The fixing component is set on the inner wall of the support frame 2 and the positions of the fixing component and the positioning component correspond to each other.

[0026] The worktable 1 includes a feed frame 6, a loading assembly, and an alignment assembly. A slide 15 is provided within the worktable 1, and the loading assembly is located within the slide 15. The feed frame 6 is slidably mounted on the worktable 1, and the loading assembly is connected to the feed frame 6. The alignment assembly includes a laser emitter 20 and a laser receiver 23. The laser emitter 20 is located on the positioning assembly, and the laser receiver 23 is located on the fixing assembly, with the laser emitter 20 and laser receiver 23 corresponding to each other. Precise positioning of the PCB board 7 can be achieved through the laser emitter 20 and laser receiver 23.

[0027] like Figure 3 As shown, the positioning assembly includes a lifting plate 10 and positioning rods 12. The lifting plate 10 is slidably disposed within a groove 9, and the positioning rods 12 are fixedly connected to the lifting plate 10. Four positioning rods 12 are provided, and all four positioning rods 12 are inserted into mounting holes 17. A first electric telescopic rod 11 is disposed within the groove 9, and the working end of the first electric telescopic rod 11 is fixedly connected to the lifting plate 10. By using the positioning rods 12 inserted into the mounting holes 17 on the PCB board 7 itself for positioning, the problem of bending of the PCB board 7 due to clamping force is avoided, and fast and accurate positioning can be achieved.

[0028] like Figure 1 As shown, the fixing assembly includes a second electric telescopic rod 4 and a limiting rod 5. Four second electric telescopic rods 4 are provided and are fixedly connected to the inner wall of the support frame 2. The limiting rod 5 is fixedly connected to the working end of the second electric telescopic rod 4, and its position corresponds to that of the positioning rod 12. When the second electric telescopic rod 4 moves the limiting rod 5 downwards, the limiting rod 5 can restrict the vertical displacement of the PCB board 7 and fix the PCB board 7.

[0029] The width of the inner wall of the feed frame 6 corresponds to the width of the PCB board 7, which can initially position the PCB board 7 during feeding. The feed frame 6 is provided with a through hole 18. When the PCB board 7 is located inside the feed frame 6, the two mounting holes 17 on the front side of the PCB board 7 are located outside the feed frame 6, while the two mounting holes 17 on the rear side are located inside the feed frame 6. The through hole 18 can prevent the feed frame 6 from blocking the laser receiver 23 from receiving the laser.

[0030] like Figure 3 As shown, the feeding assembly includes a feeding electric push rod 16 and a slider 13. The feeding electric push rod 16 is located in the slide groove 15, and the slider 13 is slidably disposed in the slide groove 15. The slider 13 is fixedly connected to the working end of the feeding electric push rod 16. A guide groove 14 is provided on the worktable 1, and the slider 13 passes through the guide groove 14 and is fixedly connected to the feeding frame 6. The feeding assembly can provide power for the sliding of the feeding frame 6.

[0031] like Figure 4As shown, a support frame 19 is fixedly connected below the lifting plate 10, and the laser emitter 20 is fixedly installed inside the support frame 19. A placement groove 22 is opened inside the limiting rod 5, and a laser receiver 23 corresponding to the laser emitter 20 is fixedly installed inside the placement groove 22. The positioning rod 12 is a hollow tube, and a through hole 21 corresponding to the positioning rod 12 is opened on the lifting plate 10. The setting of the hollow tube and the through hole 21 does not affect the laser receiver 23's reception of the laser.

[0032] A controller 8 is installed on the side wall of the workbench 1, which is connected to the laser receiver 23. The controller 8 is also connected to the feeding electric push rod 16, the first electric telescopic rod 11, and the second electric telescopic rod 4. Using the controller 8, the circuits of the feeding electric push rod 16, the first electric telescopic rod 11, and the second electric telescopic rod 4 can be automatically controlled.

[0033] The principle of this utility model

[0034] When using this application, the PCB board 7 is initially located within the feeding frame 6. During loading, the feeding electric push rod 16 is activated, and the slider 13 drives the feeding frame 6 to slide, thereby pushing the PCB board 7 downwards towards the insertion device 3. When the four mounting holes 17 of the PCB board 7 are close to the position of the positioning rod 12, the laser receiver 23 and the laser emitter 20 are activated. Then, the feeding electric push rod 16 continues to push the PCB board 7. When the PCB board 7 is in the desired positioning position, the four mounting holes 17 of the PCB board 7 are aligned with the positioning rod 12, and all four laser receivers 23 can receive the laser, the controller 8 controls the feeding electric push rod 16 to stop working, and simultaneously activates the first electric telescopic rod 11, driving the lifting plate 10 and the positioning rod 12 to rise, so that the positioning rod 12 passes through the worktable 1 and inserts into the mounting hole 17, completing the initial horizontal positioning of the PCB board 7. Figure 1 , 2 As shown.

[0035] Then, the controller 8 controls the four second electric telescopic rods 4 to start simultaneously, driving the limit rods 5 to move downward until the limit rods 5 press on the mounting holes 17 of the PCB board 7, thereby limiting the vertical movement of the PCB board 7 and completely fixing the PCB board 7.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
