Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and more specifically, it relates to a fixture for circuit board processing. Background Technology

[0002] In existing circuit board processing technologies, the design and use of fixtures face multiple challenges. First, most existing fixture structures are fixed and lack flexibility, making it impossible to adjust the angle of the fixture according to actual processing needs. Such fixed fixture structures often fail to provide optimal support and fixation when processing different circuit boards, thus affecting processing accuracy and efficiency. For example, when performing multi-angle welding or inspection, fixed fixtures cannot be adjusted to the required angle, leading to inconvenience in operation and potentially affecting welding quality and inspection results due to improper angles.

[0003] Secondly, some equipment uses pneumatic clamps equipped with suction cups to adsorb circuit boards and fix them in place. However, the pipe structure of these pneumatic clamps is relatively simple and cannot flexibly adjust the air extraction speed. The fixed air extraction speed makes it impossible to provide the best adsorption force when processing circuit boards of different materials and thicknesses. For example, for thinner circuit boards, an excessively high air extraction speed may cause the circuit board to deform or be damaged; while for thicker circuit boards, an insufficient air extraction speed may cause the clamping to be insecure and affect the processing stability. In addition, the fixed air extraction speed cannot adapt to the needs of different processing steps. For example, a higher adsorption force is required before soldering to ensure the stability of the circuit board, while a lower adsorption force is required after soldering to prevent uneven stress on the solder joints.

[0004] Furthermore, although some equipment employs devices to flexibly adjust the suction speed, these devices are relatively simple in structure and are prone to loosening due to factors such as vibration during processing or equipment movement. This loosening not only affects the adjusted suction speed but may also lead to a decrease in the overall performance of the fixture. For example, during processing, equipment vibration may cause the suction speed adjustment device to loosen, thereby changing the suction speed and affecting the processing effect. In addition, structural loosening may also reduce the adsorption effect of the suction cup, further affecting the adsorption effect, and may even cause the circuit board to fall off, resulting in equipment damage and production accidents.

A reinforcing mechanism is provided on the outside of the connecting pipe 4. The reinforcing mechanism includes a rotating sleeve 15, a rotating groove 16, a rotating hole 17, a reinforcing sleeve 18, a clamping plate 19, and a top rod 20. The rotating sleeve 15 is rotatably sleeved on the outside of the connecting pipe 4, the rotating groove 16 is opened on the rotating sleeve 15, the rotating hole 17 is opened at one end of the rotating groove 16, the reinforcing sleeve 18 is slidably sleeved on the outside of the connecting pipe 4, the clamping plate 19 is set on the top rod 20, and the top rod 20 is fixedly connected to one side of the reinforcing sleeve 18.

[0033] A corrugated pipe 21 is provided on one side of the connecting compartment 2, and one end of the corrugated pipe 21 is fixedly connected to one end of the fixed pipe 6.

[0034] A groove 22 is provided on the inner side of the connecting pipe 4, and a slider 23 is fixed on the outer side of the adapter 13, and the slider 23 is slidably disposed in the groove 22.

[0035] A reset spring 24 is connected to one side of the reinforcing sleeve 18, and the other end of the reset spring 24 is in contact with the rotating sleeve 15. A connecting spring 25 is connected to one side of the adjusting plate 5, and the two ends of the connecting spring 25 are respectively connected to the inner wall of the adjusting plate 5 and the connecting tube 4.

[0036] Multiple reinforcing rods 26 are slidably provided on the side wall of the adjusting sleeve 7, and multiple reinforcing grooves 27 are provided on the outside of the connecting pipe 4. A conical spring 28 is provided on the outer wall of the adjusting sleeve 7. One end of the reinforcing rod 26 is inserted into the reinforcing groove 27, and the other end of the reinforcing rod 26 is connected to the outer wall of the adjusting sleeve 7 through the conical spring 28.

[0037] Multiple anti-slip strips 29 are connected to the outer sides of the rotating sleeve 15, the reinforcing sleeve 18, and the adjusting sleeve 7.

[0038] In this embodiment, when the pumping speed needs to be adjusted, the rotating sleeve 15 is first rotated clockwise. The rotating sleeve 15 then drives the rotating hole 17 and the rotating groove 16 to rotate. When the rotating hole 17 moves to a position concentric with the clamping plate 19, the reinforcing sleeve 18 is pushed. The reinforcing sleeve 18 drives the push rod 20 and the clamping plate 19 to pass through the rotating hole 17. The reinforcing sleeve 18 and the rotating sleeve 15 cooperate to press the return spring 24. When the return spring 24 is pressed to its limit, the corresponding clamping plate 19 passes through the rotating hole 17 and moves to the other side of the rotating sleeve 15. Then, the rotating sleeve 15 is rotated counterclockwise. The rotating sleeve 15 drives the rotating hole 17 and the rotating groove 16 to rotate in the opposite direction. Then, the push rod 20 slides into the rotating groove 16. At this time, the push rod 20 and the clamping plate 19 cooperate to limit the reinforcing sleeve 18 to one side of the rotating sleeve 15, so that... Once the reinforcing sleeve 18 no longer limits the reinforcing rod 26, the adjusting sleeve 7 is rotated. The adjusting sleeve 7 will cause the multiple reinforcing rods 26 slidably mounted on the side wall to rotate. Then, the side wall of the reinforcing groove 27 presses against one end of the reinforcing rod 26. Due to the rounded corner design at the end of the reinforcing rod 26 and the rounded corner treatment at the edge of the reinforcing groove 27, one end of the reinforcing rod 26 will slide out of the reinforcing groove 27, and the other end of the reinforcing rod 26 will cause the conical spring 28 to stretch. At the same time, the adjusting sleeve 7 will drive the screw sleeve 11 to rotate through the movable frame 12. Since the screw sleeve 11 is movably sleeved on the outside of the screw 10 through the thread, and the slider 23 and the sliding groove 22 cooperate to limit the adapter frame 13 and the screw 10, the adapter frame 13 and the screw 10 will not rotate. Then, the screw 10 will be able to rotate through the adapter frame 13. The mounting bracket 13 drives the slider 23 to slide along the slide groove 22. At the same time, the screw 10 drives the conical block 14 to slide. Then, the conical block 14 pushes the adjusting rod 9 to move. The adjusting rod 9 then slides in the mounting bracket 8. At the same time, the other end of the adjusting rod 9 pushes the adjusting plate 5 to spread outward, causing the adjusting plate 5 to squeeze the connecting spring 25 connected on the other side. At this time, the spreading action of the adjusting plate 5 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 4, thereby changing the gas passage volume and thus changing the pumping speed. After adjusting to a suitable speed, the rotation of the adjusting sleeve 7 is stopped, and the conical spring 28 drives the reinforcing rod 26 to reset, so that one end of the reinforcing rod 26 is inserted into the corresponding reinforcing groove 27. Then, the rotating sleeve 15 is rotated clockwise again, and then the rotating sleeve 1... 5 will again cause the rotating hole 17 and rotating groove 16 to rotate. When the rotating hole 17 moves to a position concentric with the clamping plate 19, the return spring 24 pushes the reinforcing sleeve 18 to slide and reset. Then, the reinforcing sleeve 18 will cause the push rod 20 and clamping plate 19 to slide and reset. After the return spring 24 is fully reset, the clamping plate 19 connected to one end of the push rod 20 just passes through the rotating hole 17 and moves to one side of the rotating sleeve 15. Then, the rotating sleeve 15 continues to rotate, causing the rotating hole 17 and rotating groove 16 to move to a position that is not corresponding to the push rod 20 and clamping plate 19. Then, the push rod 20 and the rotating sleeve 15 cooperate to provide stable support for the reinforcing sleeve 18 and prevent the reinforcing sleeve 18 from moving. Then, the inner wall of the reinforcing sleeve 18 limits the outer end of the reinforcing rod 26 again, so that the reinforcing rod 26 will not move.Then, the reinforcing rod 26 and the reinforcing groove 27 cooperate to limit the movement of the adjusting sleeve 7, preventing it from moving and thus ensuring the structural stability after the flow rate adjustment, thereby ensuring the stable operation of the equipment.

[0039] Please see Figures 1-3 As one embodiment of the adjustment device: the adjustment device includes a connecting frame 30, a connecting shaft 31, a motor 32, and a reducer 33. The connecting frame 30 is detachably installed on both sides of the connecting compartment 2. The connecting shaft 31 is fixedly connected to one side of the connecting frame 30. The motor 32 is detachably installed on the support frame 1. The input end of the reducer 33 is connected to the output end of the motor 32, and the output end of the reducer 33 is connected to one end of one of the connecting shafts 31.

[0040] The support frame 1 is detachably provided with a bearing seat 34, and the connecting shaft 31 is rotatably installed inside the bearing seat 34.

[0041] More specifically, when the device is needed, first place the circuit board on the side of the connecting chamber 2 where the suction cup 3 is located. Then, turn on the external air extraction device connected to the other end of the bellows 21. The air extraction device then extracts air from the connecting chamber 2 through the bellows 21, the fixed pipe 6, and the connecting pipe 4, creating a negative pressure inside the connecting chamber 2. This allows the suction cup 3 to stably adsorb and clamp the circuit board. Then, turn on the motor 32 installed on the support frame 1. After being reduced in speed by the reducer 33, the output end of the motor 32 drives the connecting shaft 31 connected to the output end of the reducer 33 to rotate in the bearing seat 34. The connecting shaft 31 then drives the connecting frame 30 to rotate slowly, causing the connecting frame 30 to rotate the connecting chamber 2 and the circuit board being adsorbed and clamped at an angle. When the circuit board is rotated to an angle that is convenient for processing, turn off the motor 32.

[0042] In summary, during the use or operation of the overall equipment: when the pumping speed needs to be adjusted, first rotate the rotating sleeve 15 clockwise. The rotating sleeve 15 will then drive the rotating hole 17 and the rotating groove 16 to rotate. When the rotating hole 17 moves to a position concentric with the clamping plate 19, it pushes the reinforcing sleeve 18. The reinforcing sleeve 18 will then drive the push rod 20 and the clamping plate 19 through the rotating hole 17. The reinforcing sleeve 18 and the rotating sleeve 15 will cooperate to compress the return spring 24. When the return spring 24 is compressed to its limit, the corresponding clamping plate 19 will just pass through the rotating hole 17 and move to the other side of the rotating sleeve 15. Then, rotate the rotating sleeve 15 counterclockwise. The rotating sleeve 15 will drive the rotating hole 17 and the rotating groove 16 to rotate in the opposite direction. Then, the push rod 20 will slide into the rotating groove 16. At this time, the push rod 20 and the clamping plate 19 cooperate to limit the reinforcing sleeve 18 to the rotating sleeve. On one side, the reinforcing sleeve 18 no longer limits the reinforcing rod 26. Then, the adjusting sleeve 7 is rotated, which drives the multiple reinforcing rods 26 that are slidably set on the side wall to rotate. Then, the side wall of the reinforcing groove 27 presses against one end of the reinforcing rod 26. Due to the rounded corner design of the end of the reinforcing rod 26 and the rounded corner treatment at the edge of the reinforcing groove 27, one end of the reinforcing rod 26 will slide out of the reinforcing groove 27, and the other end of the reinforcing rod 26 will drive the conical spring 28 to stretch. At the same time, the adjusting sleeve 7 will drive the screw sleeve 11 to rotate through the movable frame 12. Since the screw sleeve 11 is movably sleeved on the outside of the screw 10 through the thread, and the slider 23 and the sliding groove 22 cooperate to limit the adapter frame 13 and the screw 10, the adapter frame 13 and the screw 10 will not rotate. Then the screw 10 The adapter 13 drives the slider 23 to slide along the groove 22, while the screw 10 drives the conical block 14 to slide. The conical block 14 then pushes the adjusting rod 9 to move, and the adjusting rod 9 slides in the mating frame 8. At the same time, the other end of the adjusting rod 9 pushes the adjusting plate 5 to spread outward, causing the adjusting plate 5 to compress the connecting spring 25 connected on the other side. At this time, the spreading action of the adjusting plate 5 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 4, thereby changing the gas passage volume and thus changing the pumping speed. After adjusting to a suitable speed, the rotation of the adjusting sleeve 7 is stopped, and the conical spring 28 drives the reinforcing rod 26 to reset, so that one end of the reinforcing rod 26 is inserted into the corresponding reinforcing groove 27. Then the rotating sleeve 15 is rotated clockwise again, and then rotated... The sleeve 15 will again drive the rotating hole 17 and the rotating groove 16 to rotate. When the rotating hole 17 moves to a position concentric with the clamping plate 19, the return spring 24 pushes the reinforcing sleeve 18 to slide and reset. Then, the reinforcing sleeve 18 will drive the push rod 20 and the clamping plate 19 to slide and reset. After the return spring 24 is fully reset, the clamping plate 19 connected to one end of the push rod 20 just passes through the rotating hole 17 and moves to one side of the rotating sleeve 15. Then, the rotating sleeve 15 continues to rotate, causing the rotating hole 17 and the rotating groove 16 to move to a position that is not corresponding to the push rod 20 and the clamping plate 19. Then, the push rod 20 and the rotating sleeve 15 cooperate to provide stable support for the reinforcing sleeve 18 and prevent the reinforcing sleeve 18 from moving. Then, the inner wall of the reinforcing sleeve 18 limits the outer end of the reinforcing rod 26 again, so that the reinforcing rod 26 will not move.Then, the reinforcing rod 26 and the reinforcing groove 27 cooperate to limit the movement of the adjusting sleeve 7, preventing it from moving and thus ensuring the structural stability after the flow rate adjustment, thereby ensuring the stable operation of the equipment.

[0043] When the device is needed, first place the circuit board on the side of the connecting chamber 2 where the suction cup 3 is located. Then, turn on the external air extraction device connected to the other end of the bellows 21. The air extraction device then extracts air from the connecting chamber 2 through the bellows 21, the fixed pipe 6, and the connecting pipe 4, creating a negative pressure inside the connecting chamber 2. This allows the suction cup 3 to stably adsorb and hold the circuit board. Then, turn on the motor 32 installed on the support frame 1. After being reduced in speed by the reducer 33, the output end of the motor 32 drives the connecting shaft 31 connected to the output end of the reducer 33 to rotate in the bearing seat 34. The connecting shaft 31 then drives the connecting frame 30 to rotate slowly, causing the connecting frame 30 to rotate the connecting chamber 2 and the circuit board being adsorbed and held at an angle. When the circuit board is rotated to an angle that is convenient for processing, turn off the motor 32.
