Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to an anti-slip clamping fixture for a PCB board of a new energy vehicle. Background Art

[0002] With the rapid development of the new energy vehicle industry, the demand for high-precision and high-performance electronic control units (ECUs) continues to increase. As one of the core components of the ECU, the quality and reliability of PCB boards are directly related to the performance of the entire system. Therefore, during the manufacturing and processing of PCB boards, reliable clamping fixtures must be used to ensure their stability and accuracy.

[0003] At present, the PCB clamping fixtures on the market mainly have the following problems: First, the single clamping method. Most traditional clamping fixtures use a side-clamping mechanical clamping device to fix the PCB board. Although this method can provide sufficient clamping force, it is easy to cause uneven pressure on the surface of the PCB board, and even cause local deformation or damage, especially for PCB boards with complex shapes or different thicknesses. Although some flexible clamping schemes can avoid the damage caused by hard clamping, they cannot provide sufficient fixing force in practical applications. Especially when a large external force needs to be applied during the processing, the PCB board is easy to slide or offset, affecting the processing accuracy; second, poor adaptability. Most of the existing clamping fixtures are designed for PCB boards of specific sizes and shapes, lacking versatility and flexibility. When encountering circuit boards of different models or specifications, different clamping tools need to be replaced, increasing production costs and time consumption; third, insufficient processing stability. In complex processing environments, such as drilling, cutting or welding processes, the PCB board may be affected by vibration or other external factors, causing it to move slightly in the clamping fixture. This slight displacement not only affects the quality of the final product, but may also cause safety accidents.

[0004] Therefore, it is urgent to develop an anti-slip clamping fixture for PCB boards of new energy vehicles. This clamping fixture combines side hard clamping and bottom flexible wrapping clamping to ensure that the PCB board can be effectively fixed in all directions to avoid sliding or displacement, and can also automatically adapt to PCB boards of different sizes and shapes, thereby improving the versatility and flexibility of the clamping fixture.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Embodiment 1: A new energy vehicle PCB board anti-slip clamping fixture, such as Figure 1-Figure 5As shown, it includes a fixed frame 1, a rubber sleeve 2, a guide rail 3, a slider 4, a connecting plate 5, a moving block 6, a guide rod 7, a splint 8, a first connecting frame 9, a spring telescopic rod 10, an air pump 11, a hollow cylinder 12, an air pipe 121, a first piston rod 13, a rack 14, a bidirectional screw rod 141, a gear 142, an air outlet pipe 15, a switching component and a pressing component. The fixed frame 1 is fixedly connected with a rubber sleeve 2, the left and right parts of the lower side of the fixed frame 1 are fixedly connected with the guide rail 3, two sliders 4 symmetrical in front and back are slidably connected in the guide rail 3, the slider 4 is rotatably connected with a connecting plate 5, and the outer ends of two adjacent connecting plates 5 are rotatably connected with a moving block 6, the middle parts of the left and right sides of the fixed frame 1 are fixedly connected, the moving block 6 is slidably connected to the adjacent guide rod 7, the upper side of the moving block 6 is fixedly connected with a splint 8, the first connecting frame 9 is fixedly connected between the two corresponding sliders 4 on the left and right, and the front and rear first connecting frames 9 are fixedly connected between them. Two spring telescopic rods 10 are fixedly connected to the left and right symmetrical parts, an air pump 11 is fixedly connected to the middle part of the lower side of the fixed frame 1, a hollow cylinder 12 is fixedly connected to the left part of the lower side of the fixed frame 1, and a gas release valve is provided on the right part of the hollow cylinder 12 and the left front part of the lower side of the fixed frame 1. An air delivery pipe 121 with a one-way valve is connected between the right part of the hollow cylinder 12 and the air pump 11, a first piston rod 13 is slidably connected in the hollow cylinder 12, and a rack 14 is fixedly connected to the left end of the first piston rod 13. The guide rail on the left side 3 is rotatably connected with a bidirectional screw rod 141, which is connected to the two sliders 4 on the left side by threads, and a gear 142 is fixedly connected to the middle of the bidirectional screw rod 141, which meshes with the rack 14, and an air outlet pipe 15 is connected between the right side of the hollow cylinder 12 and the fixed frame 1, and a switching component for switching the air flow direction after clamping the side of the PCB board is provided on the hollow cylinder 12, and a pressing component for pressing the PCB board down to fit the rubber sleeve 2 is provided on the clamping plate 8.

[0031] When using the device, the staff puts the PCB board to be processed on the rubber sleeve 2, and then controls the air pump 11 to operate. The air pump 11 operates to inflate the hollow cylinder 12 through the air pipe 121. In the initial state, the switching component blocks the right end of the hollow cylinder 12, so that the air cannot enter the air outlet pipe 15. Therefore, the air filled into the hollow cylinder 12 will squeeze the first piston rod 13 to slide to the left. The first piston rod 13 slides to the left and drives the rack 14 to move to the left. The rack 14 moves to the left and drives the gear 142 to rotate. The rotation of the gear 142 drives the bidirectional screw rod 141 to rotate. The rotation of the bidirectional screw rod 141 drives The front and rear sliders 4 on the left side slide backwards, and under the action of the first connecting frame 9, the front and rear sliders 4 on the right side also slide backwards synchronously, the spring telescopic rod 10 extends, the slider 4 slides backwards and pulls the moving block 6 to slide inwards through the connecting plate 5, and the moving block 6 slides inwards to drive the clamping plate 8 to move inwards. After the clamping plate 8 moves inwards, it is pressed against the side of the PCB board to rigidly clamp it, and the pressing component also presses the upper side of the PCB board to improve the fixing effect. When the clamping plate 8 clamps the PCB board and cannot move further inwards, the air pump 11 continues to inflate the hollow cylinder 12, which will cause the switching component to change the blocking direction, thereby making The air that subsequently enters the hollow cylinder 12 is introduced into the fixing frame 1 through the air outlet pipe 15. The air causes the rubber sleeve 2 to expand and fit the lower side of the PCB board. When the rubber sleeve 2 expands, the downward pressing component can limit the PCB board to move upward, so that the rubber sleeve 2 fits and wraps the lower side of the PCB board, thereby providing a flexible wrapping clamp for the PCB board from the lower side, ensuring that the PCB board can be effectively fixed in all directions to avoid sliding or displacement, and can also automatically adapt to PCB boards of different sizes and shapes, thereby improving the versatility and flexibility of the clamping fixture. When the PCB board is processed, the staff controls the air release valve to open, thereby fixing the PCB board. The air in the frame 1 and the hollow cylinder 12 is discharged, and the air in the fixed frame 1 is discharged so that the rubber sleeve 2 contracts and resets to release the PCB board, while the air in the hollow cylinder 12 cannot squeeze the first piston rod 13. At this time, under the action of the spring telescopic rod 10 resetting, the front and rear first connecting frames 9 move toward each other and drive the slider 4 to slide toward each other. The sliding of the slider 4 drives the bidirectional screw rod 141 and the gear 142 to reverse, thereby controlling the rack 14 and the first piston rod 13 to slide rightward and reset. While the slider 4 slides toward each other, it pushes the moving block 6 to slide outward through the connecting plate 5, and the clamping plate 8 also moves outward and separates from the PCB board.

[0032] like Figure 6 and Figure 7As shown, the switching assembly includes a mounting frame 16, a sliding rod 17, a long blocking block 171, a short blocking block 172, a first spring 18, a tapered cylinder 19, a contact rod 20, a closing plate 21, a piston cylinder 22, a second piston rod 23 and an extrusion block 24. The mounting frame 16 is fixedly connected to the right part of the hollow cylinder 12, and the sliding rod 17 is slidably connected to the mounting frame 16. The long blocking block 171 is fixedly connected to the right end of the sliding rod 17, and the short blocking block 172 is fixedly connected to the left end of the sliding rod 17. Both the short blocking block 172 and the long blocking block 171 are made of rubber. The first spring 18 is connected between the sliding rod 17 and the mounting frame 16. The right part of the hollow cylinder 12 is fixedly connected to The tapered cylinder 19 is symmetrical on both sides, and the short blocking block 172 and the long blocking block 171 are respectively located in the adjacent tapered cylinders 19. The sliding rod 17 is fixedly connected to the contact rod 20, and the lower end of the contact rod 20 extends out of the hollow cylinder 12. The contact rod 20 is fixedly connected to a closing plate 21, which fits the lower side of the hollow cylinder 12. The right part of the lower side of the hollow cylinder 12 is connected to a piston cylinder 22, and a second piston rod 23 is slidably connected in the piston cylinder 22. The lower end of the second piston rod 23 extends out of the piston cylinder 22, and the lower end of the second piston rod 23 is fixedly connected to an extrusion block 24, which is wedge-shaped, and the contact rod 20 is L-shaped. The extrusion block 24 is extruded and matched with the contact rod 20.

[0033] In the initial state, the long blocking block 171 fits with the right conical cylinder 19, thereby blocking the right part of the hollow cylinder 12. The air entering the hollow cylinder 12 will squeeze the first piston rod 13 to slide to the left, thereby driving the clamping plate 8 to move inward to clamp the PCB board. When the clamping plate 8 clamps the PCB board and cannot move inward further, the position of the first piston rod 13 remains unchanged, and the air pump 11 continues to inflate the hollow cylinder 12, which will increase the air pressure in the hollow cylinder 12. The increase in the air pressure inside the hollow cylinder 12 makes The second piston rod 23 slides downward, and the second piston rod 23 slides downward to drive the extrusion block 24 to move downward. The extrusion block 24 moves downward to squeeze the contact rod 20 to move rightward. The contact rod 20 moves rightward to drive the sliding rod 17 to slide rightward. The first spring 18 is deformed, and the sliding rod 17 slides rightward to drive the long blocking block 171 and the short blocking block 172 to move rightward. After the short blocking block 172 moves to the right, it will first contact the tapered cylinder 19 on the left, thereby blocking the end of the hollow cylinder 12 that transmits gas to the left. The long block 171 moves to the right and then separates from the tapered cylinder 19 on the right, thereby opening the end of the hollow cylinder 12 that transmits gas to the right. At this time, the air pump 11 continues to inflate the hollow cylinder 12 and the gas will be transported to the right into the air outlet pipe 15. Since the short block 172 blocks the tapered cylinder 19, the left part of the hollow cylinder 12 bursts out of the closed state, the air pressure in the left part of the hollow cylinder 12 remains unchanged, and the extrusion block 24 keeps extruding the contact rod 20 to ensure that the long block 171 remains in the open state. When the device is used, the staff controls the air release valve to open, and the air discharge pressure in the left part of the hollow cylinder 12 decreases. Under the action of the first spring 18 returning, the sliding rod 17 drives the long block 171 and the short block 172 to move to the left and reset. The contact rod 20 also moves to the left and pushes the extrusion block 24 upward, thereby controlling the second piston rod 23 to slide upward and reset. In this way, after the clamping plate 8 clamps the side of the PCB board, the gas flow direction can be automatically changed to make the rubber sleeve 2 expand and fit the lower side of the PCB board.

[0034] like Figure 1 and Figure 8 As shown, the pressing assembly includes a guide block 25, a slide bar 26, a pressing plate 27, a second connecting frame 28, a second spring 281, a contact frame 29 and an extrusion plate 30. A group of guide blocks 25 are fixedly connected at both ends of the splint 8. A group of guide blocks 25 consists of two. Slide bars 26 are slidably connected inside the guide blocks 25. A pressing plate 27 is fixedly connected between the lower sides of the two slide bars 26 of each group. A second connecting frame 28 is slidably connected between the four slide bars 26. A second spring 281 is connected between the second connecting frame 28 and the slide bars 26. Contact frames 29 are slidably connected at both ends of the splint 8. An extrusion plate 30 is fixedly connected to the outer side of the contact frame 29. The end of the extrusion plate 30 close to the second connecting frame 28 is an inclined structure, and the extrusion plate 30 is extruded and matched with the second connecting frame 28.

[0035] The second spring 281 is adapted to the redundant downward movement of the second connecting frame 28, so that the lower pressing plate 27 can press PCB boards of different thicknesses, and the lower pressing plate 27 presses the PCB board, which can also make the rubber sleeve 2 expand to better wrap the PCB board, thereby preventing the rubber sleeve 2 from expanding and pushing the PCB board upward.

[0036] Embodiment 2: Based on embodiment 1, Fig. 9 As shown, it also includes a closing component for automatically controlling the closing of the air pump 11 after clamping the PCB board. The closing component includes a cylinder 31, a third piston rod 32, a third spring 33, a pressing plate 34 and a button 35. The cylinder 31 is fixedly connected to the left part of the lower side of the fixed frame 1, and the third piston rod 32 is slidably connected in the cylinder 31. The lower end of the third piston rod 32 extends out of the cylinder 31. The third spring 33 is connected between the third piston rod 32 and the cylinder 31. The pressing plate 34 is fixedly connected to the lower side of the third piston rod 32. The button 35 is fixedly connected to the left part of the lower side of the fixed frame 1. The button 35 is electrically connected to the air pump 11, and the pressing plate 34 moves down to contact with the button 35.

[0037] When using the device, after air is filled into the fixed frame 1 and the rubber sleeve 2 expands to a certain extent, the continued intake of air into the fixed frame 1 will squeeze the third piston rod 32 to slide downward, and the third spring 33 will deform. The third piston rod 32 slides downward and drives the pressing plate 34 to move downward. After the pressing plate 34 moves downward, the button 35 is pressed, thereby controlling the air pump 11 to stop inflating. When the fixed frame 1 is deflated, the third spring 33 is reset, and the third piston rod 32 drives the pressing plate 34 to move upward and reset.

[0038] like Figure 1 and Fig.10 As shown, a cleaning component for cleaning the surface of the PCB board is also included, and the cleaning component includes a guide frame 36, a blowing frame 37, a fan 371 and an electric slide rail 38. The left part of the fixed frame 1 is fixedly connected to the guide frame 36, the blowing frame 37 is slidably connected to the guide frame 36, the upper side of the blowing frame 37 is fixedly connected to the fan 371, the fan 371 is connected to the inside of the blowing frame 37, the right part of the fixed frame 1 is fixedly connected to the electric slide rail 38, and the right part of the blowing frame 37 is slidably connected to the electric slide rail 38.

[0039] When using the device, after the PCB board is placed on the upper side of the rubber sleeve 2, the staff drives the blowing rack 37 to move forward and backward through the electric slide rail 38. When the blowing rack 37 moves forward and backward, the fan 371 transports air into the blowing rack 37, and the dust on the surface of the PCB board is cleaned by blowing air through the blowing rack 37 to facilitate subsequent processing operations.
