[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0018] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of this application may have fewer components, other components not shown in the drawings, different components, differently arranged components, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0019] See appendix Figure 1-7 This application proposes a thermistor chip pin and resistor assembly device, which includes a resistor box, a gripping unit, an assembly unit, and a conveyor line 17. The resistor box includes a rotary motor 1 and a box body 2. The output shaft of the rotary motor 1 is fixedly connected to one side of the box body 2. The box body 2 is provided with a first material hole 21, the depth of which is more than twice the height of the resistor. Multiple resistors can be stored in the first material hole 21 to facilitate gripping by the first suction nozzle 4. The rotary motor 1 drives the box body 2 to swing left and right at an angle of 120°. Under the drive of the rotary motor 1, the resistors in the box body 2 are continuously fed into the first material hole 21 to ensure the feeding requirements of the resistors.

[0020] The gripping unit includes a base 3, a first suction nozzle 4, a second suction nozzle 5, a first cylinder 6, a first slide rail 7, a first sliding block 8, a second cylinder 9, a second slide rail 10, and a second sliding block 11. The first suction nozzle 4 and the second suction nozzle 5 are fixed below the base 3 and are connected to a negative pressure generating device via air pipes. The base 3 is fixedly connected to the first sliding block 8, which is mounted on the first slide rail 7. The output shaft of the first cylinder 6 is fixedly connected to the first sliding block 8. The first cylinder 6 is mounted on the first slide rail 7 and on the second sliding block 11, which is mounted on the second slide rail 10. The output shaft of the second cylinder 9 is fixedly connected to the second sliding block 11. The first cylinder 6 drives the first suction nozzle 4 and the second suction nozzle 5 to move vertically. (Refer to attached diagram.) Figure 2 The second cylinder 9 is used to drive the first suction nozzle 4 and the second suction nozzle 5 to reciprocate along the Y-axis.

[0021] The assembly unit includes a platform 12, a sawtooth push plate 13, a telescopic motor 14, a third cylinder 15, and a pressing plate 16. The telescopic motor 14 is fixed at the bottom of the platform 12, and the output shaft of the telescopic motor 14 is fixedly connected to the sawtooth push plate 13. A mold base 18 is provided on the conveyor line 17, and the output shaft of the third cylinder 15 is fixedly connected to the pressing plate 16. The pressing plate 16 cooperates with the mold base 18. The serrated groove 20 is used to push the resistor to one side of the conveyor line 17. The third cylinder 15 is used to drive the pressing plate 16 to press down, pressing down one end of the pin 183 on the mold base 18, so that a height difference is formed between the two pins 183. After the resistor is pushed in, the third cylinder 15 drives the pressing plate 16 to move up, and the two pins 183 clamp the resistor. Specifically, when the pin 183 is stationary, the height of the pin 183 is greater than the height of the serrated push plate 13. When the pressing plate 16 is pressed down, the height of the pressed pin 183 is less than the height of the platform 12.

[0022] Specifically, the mold base 18 includes a cardboard shell 181, adhesive tape 182, and pins 183. The pins 183 are located between the cardboard shell 181 and the adhesive tape 182, and the adhesive tape 182 is fixed to one side of the cardboard shell 181 and the pins 183. The mold base 18 is mounted on the conveyor line 17, with the cardboard shell 181 in contact with the conveyor line 17 and the pins 183 facing the platform 12.

[0023] The base 3 is provided with a second material hole 31, and the serrated push plate 13 is provided with a serrated groove 20 on the side near the conveyor line 17. The serrated groove 20 cooperates with the pin 183. The first material hole 21, the second material hole 31 and the serrated groove 20 are arranged correspondingly, and the first suction nozzle 4 and the second suction nozzle 5 correspond to the cavities of the above three.

[0024] The bottom of the pressing plate 16 has several protrusions, which cooperate with pins 183, including a left pin and a right pin. The protrusions cooperate with the left pin. When the pressing plate 16 is pressed down, the protrusions cooperate with the left pin, thereby causing the left pin to move down, forming a height difference between the left pin and the right pin, which facilitates the entry of the resistor.

[0025] Among them, a roller 19 is provided above the conveyor line 17, and the roller 19 is used to drive the mold base 18 on the conveyor line 17 to move.

[0026] In use, the rotary motor 1 drives the box 2 to sway left and right. During the swaying, the resistor inside the box 2 enters the first material hole 21. Then, the box 2 is flattened to wait for the resistor to be picked up. Subsequently, the second cylinder 9 operates, driving the first suction nozzle 4 to move towards the first material hole 21 of the box 2. After the two are aligned, the first cylinder 6 operates, and the first suction nozzle 4 moves down to contact the resistor in the first material hole 21. Then, the negative pressure generating device operates, and the first suction nozzle 4 adsorbs the resistor. Then, the first cylinder 6 operates to move the first suction nozzle 4 up, and the second cylinder 9 operates, driving the base to move towards the base platform 3. After the first suction nozzle 4 is aligned with the second material hole 31, the first cylinder 6 moves down to put the resistor into the second material hole 31. Inside the material hole 31, the first suction nozzle 4 continues to grab the resistor from the box 2. While the first suction nozzle 4 is sending the first material hole 21 to the second material hole 31, the second suction nozzle 5 sends the resistor from the second material hole 31 to the serrated groove 20. The two are carried out simultaneously. When the telescopic motor 14 drives the serrated push plate 13 to move towards the pin 183, the third cylinder 15 drives the pressing plate 16 to press down. The protrusion of the pressing plate 16 presses down the left pin of the pin 183 to form a height difference. The resistor is pushed before the pin 183. Then the third cylinder 15 moves up. After the pressing plate 16 moves up, the left and right pins of the pin 183 clamp the resistor. The roller 19 drives the mold base 18 to continue moving, repeating the above assembly operation.

[0027] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
