Description

Technical Field

[0001] This utility model relates to the field of circuit board stacking technology, and in particular to an adaptive high-precision circuit board tray arrangement device. Background Technology

[0002] Printed circuit board (PCB) tray loading equipment is used in the electronics manufacturing industry to automatically sort, arrange, stack, or load PCBs and their semi-finished products onto designated trays. It achieves precise operation through the cooperation of mechanical structure and control system, which can replace manual labor to improve production efficiency, ensure tray loading accuracy, reduce PCB damage, and reduce labor costs. It can also adapt to diverse production needs and connect to automated production lines. It is widely used in consumer electronics, automotive electronics and other fields, and is an important automated equipment for improving production quality and competitiveness.

[0003] However, in the existing technology, when processing circuit boards of different sizes, thin boards or irregularly shaped boards, the circuit board tray equipment uses rigid grippers and other fixed gripping methods, which cannot dynamically adjust the clamping force and contact method according to the material characteristics. This leads to material deformation or stress concentration during the gripping process. Thin boards may bend due to excessive clamping, and irregularly shaped boards may be damaged at the edges and corners due to improper force points. It lacks adaptive high-precision fixing and traying for different types of circuit boards. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an adaptive high-precision circuit board tray arrangement device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive high-precision circuit board sloshing device, comprising a sloshing mechanism, a clamping mechanism fixedly connected to the lower part of the sloshing mechanism, the sloshing mechanism comprising a Y-axis moving servo component, an X-axis moving servo component mounted on the upper part of the Y-axis moving servo component, a Z-axis moving servo component mounted on the upper part of the X-axis moving servo component, a first cylinder mounted on the side of the Z-axis moving servo component, the clamping mechanism comprising a first mounting frame, the first mounting frame being fixedly connected to the lower part of the first cylinder, and a second cylinder mounted on the inner side of the first mounting frame, a fixed plate being fixedly connected to the end of the second cylinder, two mounting plates being fixedly connected to the bottom of the fixed plate, a servo motor being fixedly connected to the lower part of the mounting plate, a lead screw being fixedly connected to the output end of the servo motor, a lead block being threaded onto the surface of the lead screw, a fixed frame being fixedly connected to the lower part of the lead block, and a clamping plate being mounted on the lower part of the fixed frame;

[0006] The bottom of the No. 1 mounting bracket is fixedly connected to an adsorption support mechanism, which is located in the middle of the two mounting plates.

[0007] Preferably, a slide rail is fixedly connected to the bottom of the first mounting bracket, a slider is slidably connected to the surface of the slide rail, and the slider is fixedly connected to the upper part of the mounting plate.

[0008] Preferably, a second slide rail is fixedly connected to the bottom of the mounting plate, and a second slider is slidably connected to the surface of the second slide rail. The second slider is fixedly connected to the fixing frame.

[0009] Preferably, one end of the lead screw is rotatably connected to the mounting plate, and the lead block is slidably connected to the mounting plate.

[0010] Preferably, the adsorption support mechanism includes a third cylinder, which is fixedly connected to the bottom of a first mounting bracket, and a second mounting bracket is fixedly connected to the bottom of the third cylinder. A suction cup assembly is mounted on the surface of the second mounting bracket, and the suction cup assembly is externally connected to a control system.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the three-dimensional precise adjustment of the Y-axis, X-axis, and Z-axis moving servo components, combined with the servo motor driving the lead screw in the clamping mechanism to slide the lead block, allows for precise adjustment of the initial distance between the two clamping plates via the fixed frame. Then, the second cylinder pushes the fixed plate, causing the mounting plate to slide along the first slide rail, thus opening and closing the clamping plates. This adapts to the clamping requirements of circuit boards of different sizes. For thin or irregularly shaped boards, after adjusting the initial distance of the clamping plates for limiting, the third cylinder in the adsorption support mechanism pushes the second mounting frame to move the suction cup assembly downwards. Combined with the external control system, this achieves adsorption and fixation of the middle part of the circuit board, avoiding bending or corner damage caused by rigid clamping. Simultaneously, the sliding design of the first and second sliders enhances clamping flexibility. Finally, through the precise drive of each servo component, high-precision placement of the circuit board is achieved. The overall structure takes into account both adaptive fixing and high-precision placement of different types of circuit boards, effectively reducing material damage and improving production adaptability.

[0013] 2. In this utility model, the initial downward height of the first cylinder is precisely adjusted by the Z-axis movement servo component, which can simultaneously adjust the initial downward distance of the suction cup component. In conjunction with the third cylinder in the adsorption support mechanism, the second mounting bracket is pushed to drive the downward movement of the suction cup component. This not only avoids damage to thick circuit boards caused by excessive pressure from the thrust of the third cylinder, but also ensures that the suction cup component fully adheres to the surface of the circuit board when adsorbing thinner circuit boards, thereby ensuring the firmness of the adsorption and fixation. This effectively solves the problem of improper pressure or insecure fixation that easily occurs during the adsorption process of circuit boards of different thicknesses, and improves the adaptability and fixation reliability of the equipment for circuit boards of various thicknesses.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5As shown, this utility model provides an adaptive high-precision circuit board sloshing device, including a sloshing mechanism 1. A clamping mechanism 2 is fixedly connected to the lower part of the sloshing mechanism 1. The sloshing mechanism 1 includes a Y-axis motion servo component 11, an X-axis motion servo component 12 is mounted on the upper part of the Y-axis motion servo component 11, and a Z-axis motion servo component 13 is mounted on the upper part of the X-axis motion servo component 12. A first cylinder 14 is mounted on the side of the Z-axis motion servo component 13. The clamping mechanism 2 includes a first mounting bracket 21. 1 is fixedly connected to the lower part of cylinder 14, and cylinder 22 is installed on the inner side of mounting bracket 21. A fixing plate 23 is fixedly connected to the end of cylinder 22. Two mounting plates 24 are fixedly connected to the bottom of the fixing plate 23. A servo motor 27 is fixedly connected to the lower part of the mounting plate 24. A lead screw 28 is fixedly connected to the output end of the servo motor 27. A lead block 29 is threaded on the surface of the lead screw 28. A fixing frame 210 is fixedly connected to the lower part of the lead block 29. A clamping plate 213 is installed at the lower part of the fixing frame 210.

[0023] The bottom of the first mounting bracket 21 is fixedly connected to an adsorption support mechanism 3, which is located in the middle of the two mounting plates 24. The bottom of the first mounting bracket 21 is fixedly connected to a first slide rail 25, and a first slider 26 is slidably connected to the surface of the first slide rail 25. The first slider 26 is fixedly connected to the upper part of the mounting plate 24. The bottom of the mounting plate 24 is fixedly connected to a second slide rail 211, and a second slider 212 is slidably connected to the surface of the second slide rail 211. The second slider 212 is fixedly connected to a fixed frame 210. One end of the lead screw 28 is rotatably connected to the mounting plate 24, and the lead block 29 is slidably connected to the mounting plate 24. The adsorption support mechanism 3 includes a third cylinder 31, which is fixedly connected to the bottom of the first mounting bracket 21. The bottom of the third cylinder 31 is fixedly connected to a second mounting bracket 32, and a suction cup assembly 33 is mounted on the surface of the second mounting bracket 32. The suction cup assembly 33 is externally connected to a control system.

[0024] The specific settings and functions of this embodiment are described below. The circuit board is clamped and fixed by the clamping mechanism 2. Depending on the size of the circuit board, the lead screw 28 is rotated by the servo motor 27, causing the lead block 29 to slide along the mounting plate 24, thereby driving the fixing frame 210 to adjust its position. This allows for precise adjustment of the initial distance between the two clamping plates 213. Subsequently, the fixing plate 23 is moved closer to each other by the second cylinder 22, so that the clamping plate 213 can clamp and fix circuit boards of different sizes. When clamping thin or irregularly shaped boards, the initial distance between the two clamping plates 213 is appropriately increased. After the clamping plates 213 limit the movement on both sides, the third cylinder 31 pushes the second mounting frame 32 and the suction cup assembly 33 downward. The suction cup assembly 33 is controlled by the external control system to adsorb and fix the middle of the thin or irregularly shaped board, improving the stability of the fixation and preventing excessive deformation or damage to the thin or irregularly shaped board.

[0025] After the circuit board is fixed, its horizontal position is adjusted by the Y-axis motion servo component 11 and the X-axis motion servo component 12, and its height is adjusted by the Z-axis motion servo component 13. This allows for precise placement of the circuit board according to the desired location. The Y-axis motion servo component 11, X-axis motion servo component 12, and Z-axis motion servo component 13 together constitute the device's three-dimensional movement adjustment system. Each servo component includes a servo motor, precision guide rail, gears, racks, and a matching slider. The servo motor drives the gears to rotate, and the gears mesh with the racks to drive the slider. The device slides precisely along a precision guide rail to achieve linear displacement adjustment along the corresponding axis. The Y-axis moving servo component 11 provides basic moving support for the device along the Y direction, while the X-axis moving servo component 12 installed on top of it can achieve X-direction displacement adjustment based on the Y-axis movement. The Z-axis moving servo component 13 on top of the X-axis moving servo component 12 completes the lifting and lowering adjustment in the Z direction (vertical direction). The three components work together through precise motor control and gear rack transmission to achieve high-precision position adjustment of the clamping mechanism 2 and the adsorption support mechanism 3 in three-dimensional space, providing a stable moving foundation for precise gripping and tray placement of the circuit board.

[0026] With the precise three-dimensional adjustment of the Y-axis motion servo component 11, X-axis motion servo component 12, and Z-axis motion servo component 13, and in conjunction with the servo motor 27 driving the lead screw 28 to slide the lead block 29 in the clamping mechanism 2, the initial distance between the two clamping plates 213 can be precisely adjusted via the fixing frame 210. Then, combined with the second cylinder 22 pushing the fixing plate 23 to drive the mounting plate 24 to slide along the first slide rail 25, the clamping plates 213 open and close, thus adapting to the clamping requirements of circuit boards of different sizes. For thin or irregularly shaped boards, the initial distance between the clamping plates 213 can be increased to achieve... After the limit is reached, the third cylinder 31 in the adsorption support mechanism 3 pushes the second mounting bracket 32 ​​to move the suction cup assembly 33 downward. In conjunction with the external control system, the middle part of the circuit board is adsorbed and fixed, avoiding bending or corner damage caused by rigid clamping. At the same time, the sliding design of the first slider 26 and the second slider 212 improves the clamping flexibility. Finally, through the precise drive of each servo component, the circuit board is placed with high precision. The overall structure takes into account the adaptive fixing and high-precision placement of different types of circuit boards, effectively reducing material damage and improving production adaptability.

[0027] Example 2: Figure 1 , Figure 3 and Figure 4As shown, a cylinder 14 is mounted on the side of the Z-axis moving servo component 13, and the adsorption support mechanism 3 includes a cylinder 31. The cylinder 31 is fixedly connected to the bottom of the mounting bracket 21, and a mounting bracket 32 ​​is fixedly connected to the bottom of the cylinder 31. A suction cup assembly 33 is mounted on the surface of the mounting bracket 32, and the suction cup assembly 33 is externally connected to the control system.

[0028] The specific settings and functions of this embodiment are described below. Depending on the thickness of the circuit board, the initial downward height of the first cylinder 14 is precisely adjusted by the Z-axis movement servo component 13, thereby adjusting the initial downward distance of the suction cup component 33. This avoids excessive pressure on the thicker circuit board when the third cylinder 31 pushes the suction cup component 33 downward, and also avoids insufficient contact between the suction cup component 33 and the thinner circuit board when adsorbing it, resulting in insecure fixation.

[0029] The initial downward height of cylinder 14 is precisely adjusted by the Z-axis servo component 13, which in turn adjusts the initial downward distance of suction cup component 33. This, combined with the downward movement of suction cup component 33 driven by cylinder 31 in suction support mechanism 3, avoids excessive pressure on thicker circuit boards caused by the thrust of cylinder 31, while ensuring that suction cup component 33 fully adheres to the surface of thinner circuit boards during suction. This ensures a firm and secure suction, effectively solving the problem of improper pressure or insecure fixation that easily occurs during the suction process of circuit boards of different thicknesses. This improves the equipment's adaptability and fixation reliability for circuit boards of various thicknesses.

[0030] The device is used and works as follows: The circuit board is clamped and fixed by the clamping mechanism 2. Depending on the size of the circuit board, the lead screw 28 is rotated by the servo motor 27, which causes the lead block 29 to slide along the mounting plate 24, thereby driving the fixing frame 210 to adjust its position. This allows for precise adjustment of the initial distance between the two clamping plates 213. Then, the fixing plate 23 is moved closer to each other by the second cylinder 22, so that the clamping plate 213 can clamp and fix circuit boards of different sizes. When clamping thin or irregularly shaped boards, the initial distance between the two clamping plates 213 is appropriately increased. After the clamping plates 213 limit the movement on both sides, the third cylinder 31 pushes the second mounting frame 32 and the suction cup assembly 33 downward. The suction cup assembly 33 is controlled by the external control system to adsorb and fix the middle of the thin or irregularly shaped board.

[0031] Depending on the thickness of the circuit board, the initial downward height of the first cylinder 14 is precisely adjusted by the Z-axis movement servo component 13, thereby adjusting the initial downward distance of the suction cup component 33.

[0032] After the circuit board is fixed, the horizontal position of the circuit board is adjusted by the Y-axis motion servo component 11 and the X-axis motion servo component 12, and the height of the circuit board is adjusted by the Z-axis motion servo component 13, so that the circuit board can be accurately placed according to the required placement position.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
