[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 5As shown, the present invention provides a pin bending device for temperature sensor resistor production, including a workbench 1, a conveyor belt 2 is penetrated and installed on one side of the middle of the workbench 1, a conveyor belt 2 is penetrated and installed on one side of the middle of the workbench 1 away from the conveyor belt 2, baffles 4 are fixedly connected to both sides of the top of the workbench 1, and the baffles 4 cooperate with the conveyor belt 1 2 and the conveyor belt 2 3, a resistance block 5 is installed on the top of the workbench 1 between the conveyor belt 1 2 and the conveyor belt 2 3, and a U-shaped frame 6 is fixedly connected to the top of the workbench 1 A cylinder 7 is installed on one side of the bottom of the U-shaped frame 6, and a slide groove 8 is opened on both sides of the output end of the cylinder 7. The outer wall of the cylinder 7 is slidably connected with a connecting plate 9, and the connecting plate 9 passes through the inner wall of the cylinder 7 and is fixedly connected with sliders 10 on both sides, and the slider 10 slides in the slide groove 8. The end of the connecting plate 9 away from the slide groove 8 is fixedly connected with a lower pressure plate 14, and the lower pressure plate 14 cooperates with the two baffles 4. One end of the output end of the cylinder 7 is fixedly connected with a bending block 11, and the bending block 11 cooperates with the resistance block 5.

[0031] The above scheme is adopted: first, the temperature sensor is placed on the conveyor belt 2 and the temperature sensor is driven to move by the conveyor belt 2. When it moves to the contact block 5, the temperature sensor will be contacted by the contact block 5. At this time, the pin of the temperature sensor will be placed on the surface of the contact block 5, and then the cylinder 7 is turned on to drive the bending block 11 to move downward to bend the pin placed on the contact block 5. At the same time, the connecting plate 9 will also drive the lower pressure plate 14 and the rubber plate 15 to move downward under the bending block 11. At the same time, the sliding rod 13 slides in the connecting sleeve 12, and the temperature sensor is clamped by the descent of the lower pressure plate 14. At the same time, the rubber plate 15 squeezes and fixes the temperature sensor. When the lower pressure plate 14 contacts the baffle 4, the bending block 11 will continue to move downward to squeeze the pin, and the connecting plate 9 will slide in the slide groove 8 through the slider 10. The above structure solves the problem of cumbersome clamping operation when bending the pin of the temperature sensor.

[0032] like Figures 1 to 9 As shown, the workbench 1 is provided with a second slide groove 16 at the bottom of the abutment block 5, a spring 17 is fixedly connected inside the second slide groove 16, and one end of the spring 17 away from the second slide groove 16 is fixedly connected to the abutment block 5, and the workbench 1 is provided with an output groove 18 on both sides of the second slide groove 16, and two output grooves 19 are provided on opposite sides of the two baffles 4, and the inner walls of the two output grooves 19 are provided with a card slot 20;

[0033] Extrusion grooves 21 are provided on both sides of the abutment block 5. Springs 22 are installed inside the two extrusion grooves 21. A clamping block 23 is installed on the side of the spring 22 away from the extrusion groove 21. The clamping block 23 slides in the extrusion groove 21 and cooperates with the clamping groove 20.

[0034] A second connecting plate 24 is fixedly connected to the top of the bending block 11, and the second connecting plate 24 passes through the output end of the cylinder 7. A U-shaped output rod 25 is fixedly connected to one end of the connecting plate 24 away from the bending block 11, and the U-shaped output rod 25 slides in the output slot 18 and the output slot 2 19;

[0035] The two sides of the U-shaped output rod 25 are fixedly connected with rotating rods 26, and the ends of the two rotating rods 26 away from the U-shaped output rod 25 are rotatably connected with extrusion blocks 27, and the extrusion blocks 27 are matched with the clamping blocks 23;

[0036] The two U-shaped output rods 25 are provided with arc grooves 28 on one side close to the rotating rod 26, and the inner cavities of the two arc grooves 28 are fixedly connected with arc springs 30;

[0037] One end of the arc spring 30 away from the arc groove 28 is fixedly connected to the limit rod 29, and the limit rod 29 slides in the arc groove 28, and the side of the limit rod 29 away from the arc groove 28 is fixedly connected to the extrusion block 27;

[0038] Both ends of the U-shaped output rod 25 are fixedly connected with upper pull blocks 31 , and the upper pull blocks 31 cooperate with the abutment blocks 5 .

[0039] The above scheme is adopted: after the temperature sensor is bent, the cylinder is started, and the extrusion block 27 is driven to move upward through the U-shaped output rod 25, and the extrusion block 27 will contact the block 23 through the oblique angle. Through the force of the contact and upward movement, the block 23 slides into the extrusion groove 21 to compress the spring 22, and at the same time the block 23 will be separated from the groove 20, one half of the block 23 will be stuck in the groove 20, and the other one third will contact and cooperate with the extrusion block 27.

[0040] Then the resistance block 5 will be pulled downwards into the second slide groove 16 by the moving elastic force of the spring 17, and will be out of contact with the temperature sensor when the resistance block 5 is pressed down. At this time, the pin of the temperature sensor has been bent. After the temperature sensor is out of contact with the resistance block 5, the temperature sensor will be conveyed forward by the conveyor belt 1 2 and the processed temperature sensor will be conveyed to the conveyor belt 2 3. The processed temperature sensor will be unloaded by the conveyor belt 2 3, so as to avoid the problem of low efficiency caused by the need to remove the temperature sensor after the bending of the temperature sensor pin is completed and then re-clamping and fixing the unbent one.

[0041] The U-shaped output rod 25 will continue to move upward, and drive the resistance block 5 in the second slide groove 16 to move upward through the upper pull block 31. When the resistance block 5 moves upward to the card slot 20, the card block 23 will be stuck in the card slot 20 through the elastic force of the second spring 22. At this time, the bending block 11 stops moving and completes the reset. At the same time, the resistance block 5 will resist the next temperature sensor.

[0042] like Figures 1 to 7 As shown, a connecting sleeve 12 is fixedly connected to the bottom of the U-shaped frame 6 away from the cylinder 7, a sliding rod 13 is slidably connected inside the connecting sleeve 12, and an end of the sliding rod 13 away from the connecting sleeve 12 is fixedly connected to the lower pressing plate 14;

[0043] A rubber plate 15 is installed at the bottom of the lower pressing plate 14 , and the rubber plate 15 is provided to reduce the squeezing force on the temperature sensor.

[0044] With the above solution, the sliding rod 13 slides in the connecting sleeve 12, the temperature sensor is clamped by the lower pressing plate 14, and the rubber plate 15 squeezes and fixes the temperature sensor.

[0045] The working principle and use process of the present invention:

[0046] During operation, the temperature sensor is first placed on the conveyor belt 2 and driven by the conveyor belt 2 to move. When it moves to the contact block 5, the temperature sensor will be contacted by the contact block 5. At this time, the pin of the temperature sensor will be placed on the surface of the contact block 5, and then the cylinder 7 is turned on to drive the bending block 11 to move downward to bend the pin placed on the contact block 5. At the same time, the connecting plate 9 will also drive the lower pressing plate 14 and the rubber plate 15 to move downward under the bending block 11. At the same time, the sliding rod 13 slides in the connecting sleeve 12, and the temperature sensor is clamped by the descent of the lower pressing plate 14. At the same time, the rubber plate 15 squeezes and fixes the temperature sensor. When the lower pressing plate 14 contacts the baffle 4, the bending block 11 will continue to move downward to squeeze the pin, and the connecting plate 9 will slide in the slide groove 8 through the slider 10. The above structure solves the problem of cumbersome clamping operation when bending the pin of the temperature sensor.

[0047] When the bending block 11 moves downward, the connecting plate 24 and the U-shaped output rod 25 will move downward at the same time. When the U-shaped output rod 25 is pressed downward, the bottom side of the extrusion block 27 will contact the clamping block 23, so that the extrusion block 27 drives the limiting rod 29 to slide in the arc groove 28, and the arc spring 30 is compressed, so that the extrusion block 27 rotates to prevent the extrusion block 27 from being stuck on the clamping block 23 when it moves downward.

[0048] After the temperature sensor is bent, the cylinder is started to reset the assembly when it is lowered. When it is reset and moved upward, the extrusion block 27 is driven to move upward by the U-shaped output rod 25, and the extrusion block 27 is contacted with the block 23 by the oblique angle of the extrusion block 27. The block 23 slides into the extrusion groove 21 through the force of the contact and upward movement, so that the spring 22 is compressed, and the block 23 is separated from the card slot 20, and then the contact block 5 is pulled downward into the slide groove 216 by the moving elastic force of the spring 17. When the contact block 5 is pressed down, it will be separated from the contact with the temperature sensor. At this time, the pin of the temperature sensor has been bent. After the temperature sensor is separated from the contact of the contact block 5, the temperature sensor is continued to be forwarded by the conveyor belt 1 2. The processed temperature sensor is transferred to the conveyor belt 2 3, and the processed temperature sensor is unloaded by the conveyor belt 2 3. At this time, it is avoided that the temperature sensor needs to be removed after the bending of the temperature sensor pin is completed, and the unbent one is clamped and fixed again, resulting in low efficiency.

[0049] At this time, the U-shaped output rod 25 will continue to move upward, and drive the resistance block 5 in the second slide groove 16 to move upward through the upper pull block 31. When the resistance block 5 moves upward to the card slot 20, the card block 23 will be stuck in the card slot 20 through the elastic force of the second spring 22. At this time, the bending block 11 stops moving and completes the reset. At the same time, the resistance block 5 will resist the next temperature sensor.
