Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to an automatic gripping device for PCB board production lines. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. During PCB production, the PCBs are often transported to the required location, and then the processed PCBs are collected for subsequent operations.

[0003] In existing technologies, PCB board gripping is mostly done manually or with simple mechanical devices. Manual gripping is inefficient and can easily lead to fatigue from prolonged work, resulting in unstable gripping and affecting production progress. Simple mechanical devices lack flexibility and precision, and due to the thinness of the PCB board, gripping failures are common, further impacting production efficiency. Utility Model Content

[0005] This utility model also proposes an automatic gripping device for a PCB board production line, comprising: two sets of support plates, a connecting frame fixed at the top of the support plates, a gripping component on the connecting frame, and a lifting component between the two sets of support plates; The gripping assembly includes a servo motor mounted on the top of the connecting frame. A disk is fixed to the output end of the servo motor. A first electric push rod is fixed to the bottom end of the disk. A cross-shaped plate is fixed to the movable end of the first electric push rod. Square blocks are fixed to the four corners of the bottom end of the cross-shaped plate. Horizontal plates are fixed to the bottom ends of the four sets of square blocks. Two sets of clamping plates are slidably connected to the inside sides of the horizontal plates. A second electric push rod is installed inside the square blocks. A U-shaped frame is fixed to the movable end of the second electric push rod. Movable plates are fixed to the bottom sides of the U-shaped frame. Inclined plates that are fixedly connected to the top of the clamping plates are provided on the inside sides of the movable plates. The lifting assembly includes a fixed plate installed between the two sets of support plates. The fixed plate has a fixed shaft at its top, a top rod that slides on the inner wall of the fixed shaft, a top block that is fixed at the upper end of the top rod, a connecting pipe that is provided at the lower end of one side of the fixed shaft, and a pressing rod that is slidably connected to the inner wall of the connecting pipe away from the fixed shaft. An L-shaped connecting rod that is fixed to the cross-shaped plate is provided directly above the pressing rod.

[0006] According to some embodiments of the present invention, both sets of support plates are provided with a conveyor belt on one upper end, and a placement platform for placing PCB boards is installed on the side of the support plate away from the conveyor belt.

[0007] According to some embodiments of the present invention, a protective pad is provided at the lower end of one side of the clamping plate, and a slider is fixed at the top of the clamping plate. A groove for the slider to move is provided inside the horizontal plate.

[0008] According to some embodiments of the present invention, the movable plate has an inclined groove inside, and the inclined groove is slidably connected to the inclined plate.

[0010] According to some embodiments of the present invention, the top block is provided in two sets, and the two sets of top blocks are disposed between two sets of conveyor belts.

[0011] The embodiments of this utility model have at least the following beneficial effects: In this invention, the cooperation between the inclined plate and the moving plate causes the clamping plates on both sides to slide inward along the groove inside the horizontal plate, thereby clamping the PCB board. At the same time, by setting clamping plates at the bottom of the cross-shaped plate, the PCB board can be placed and gripped simultaneously, which greatly improves the gripping efficiency and meets the needs of large-scale PCB production lines for efficient and stable gripping. During the descent of the cross-shaped plate, it pushes the extrusion rod to compress the gas inside the connecting pipe, causing the top rod to push the top block to rise, which can play a certain lifting assistance role for the PCB board on the conveyor belt, making it easier for the clamping plates to grip the board. This effectively avoids gripping failures caused by thin PCB boards or excessively tight bonding between boards during the gripping process. Attached Figure Description

[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5An automatic gripping device for a PCB production line is shown, comprising: two sets of support plates 100, a connecting frame 120 fixed at the top of the support plate 100, a gripping component 200 provided on the connecting frame 120, and a lifting component 300 provided between the two sets of support plates 100. The gripping component 200 includes a servo motor 210 mounted on the top of the connecting frame 120. A disk 220 is fixed to the output end of the servo motor 210. A first electric push rod 230 is fixed to the bottom end of the disk 220. A cross-shaped plate 240 is fixed to the movable end of the first electric push rod 230. Square blocks 250 are fixed to the four corners of the bottom end of the cross-shaped plate 240. A horizontal plate 260 is fixed to the bottom end of the four sets of square blocks 250. Two sets of clamping plates 270 are slidably connected to both sides inside the horizontal plate 260. A second electric push rod 280 is installed inside the square blocks 250. A U-shaped frame 290 is fixed to the movable end of the second electric push rod 280. A movable plate 2910 is fixed to both sides of the bottom end of the U-shaped frame 290. An inclined plate 2920 is provided on both sides inside the movable plate 2910 and is fixedly connected to the top of the clamping plate 270. The lifting assembly 300 includes a fixed plate 310 installed between two sets of support plates 100. The top of the fixed plate 310 is provided with a fixed shaft 320. A top rod 330 slides on the inner wall of the fixed shaft 320. A top block 340 is fixed at the upper end of the top rod 330. A connecting pipe 350 is provided at the lower end of one side of the fixed shaft 320. A pressing rod 360 is slidably connected to the inner wall of the connecting pipe 350 away from the fixed shaft 320. An L-shaped connecting rod 370 is provided directly above the pressing rod 360 and is fixed to the cross-shaped plate 240.

[0019] Multiple PCBs are evenly placed on the conveyor belt 110 for transport. When two PCBs are below the two gripping components 200, the conveyor belt 110 is stopped, and the first electric push rod 230 is activated to push the cross-shaped plate 240 downward, thereby causing the horizontal plate 260 and clamping plate 270 to descend to a suitable height. At this time, the second electric push rod 280 is activated, which pushes the U-shaped frame 290 upward. The U-shaped frame 290 causes the moving plate 2910 to move upward. An inclined groove 2911 is formed inside the movable plate 2910, and the inclined groove 2911 is slidably connected to the inclined plate 2920. During the upward movement of the movable plate 2910, the inclined plate 2920 will drive the clamping plates 270 on both sides to slide inward along the sliding groove 261 inside the horizontal plate 260, thereby clamping the PCB board. After clamping, the first electric push rod 230 retracts, driving the gripped PCB board to rise. At the same time, during the descent of the cross-shaped plate 240, it will drive the L-shaped connecting rod 370 to move downward. When the connecting rod 370 moves down to contact the extrusion rod 360, it pushes the extrusion rod 360 to compress the gas inside the connecting tube 350. Under the action of air pressure, the push rod 330 inside the fixed shaft 320 rises, which pushes the top block 340 to rise. This can play a certain lifting assistance role for the PCB board on the conveyor belt 110, making it easier for the clamping plate 270 to grip. This effectively avoids the situation where the gripping of the PCB board fails due to its thinness or the tightness between the boards. After the gripping is completed, the servo motor 210 is started to drive the disc 220 to rotate, which drives the first electric push rod 230 to rotate synchronously. This causes the gripping component 200 to rotate 90 degrees, which allows the gripped PCB board to be moved to the placement table 130. At the same time, by setting clamping plates 270 at the bottom of the cross-shaped plate 240, the PCB board can be placed and gripped at the same time, which greatly improves the gripping efficiency and meets the needs of large-scale PCB production lines for efficient and stable gripping.

[0020] In this embodiment, a conveyor belt 110 is provided on the upper end of one side of each of the two sets of support plates 100, and a placement platform 130 for placing PCB boards is installed on the side of the support plate 100 away from the conveyor belt 110. A protective pad 271 is provided on the lower end of one side of each clamping plate 270, and a slider 272 is fixed at the top of the clamping plate 270. A groove 261 for the slider 272 to move is provided inside the horizontal plate 260. An inclined groove 2911 is opened inside the moving plate 2910. The inclined groove 2911 is slidably connected to the inclined plate 2920. The top of the extrusion rod 360 is on the same horizontal plane as the top of the support plate 100. Two sets of top blocks 340 are provided, and the two sets of top blocks 340 are located between the two sets of conveyor belts 110.

[0021] The protective pad 271 set on the lower side of the clamping plate 270 can effectively avoid damage to the PCB board during the gripping process, ensuring the quality of the PCB board. The cooperation between the slider 272 fixed at the top of the clamping plate 270 and the internal slide groove 261 of the horizontal plate 260 makes the movement of the clamping plate 270 more stable and precise, further improving the accuracy and stability of gripping. In addition, two sets of top blocks 340 are set between the two sets of conveyor belts 110. When the lifting component 300 is working, it can evenly apply lifting force to the PCB board on the conveyor belt 110, ensuring that all PCB boards can be lifted smoothly, making it easy for the clamping plate 270 to grip.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
