[0034] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] See also Figure 1-8 , a resistance wire roll welding encapsulation device for sensor production, comprising a resistance wire conveying mechanism 1, a roll welding mechanism 2, a carrier plate wiring mechanism 3 and a tape fixing mechanism 4;

[0037] The resistor wire conveying mechanism 1 comprises a resistor conveying belt 11 and a wire conveying belt 12 which operate synchronously, wherein the resistor conveying belt 11 is provided with a resistor slot 111 corresponding to the resistor 5, and the wire conveying belt 12 is provided with a wire slot 121 corresponding to the wire 6, wherein the resistor slot 111 and the wire slot 121 are arranged opposite to each other, and a resistor pin extension opening 112 is provided at one end of the resistor slot 111 close to the wire slot 121, and a wire pin extension opening 122 is provided at one end of the wire slot 121 close to the resistor slot 111;

[0038] A resistor groove 111 is provided on the resistor conveyor belt 11, and a wire groove 121 is provided on the wire conveyor belt 12. A resistor pin extension opening 112 is provided at one end of the resistor groove 111 close to the wire groove 121, and a wire pin extension opening 122 is provided at one end of the wire groove 121 close to the resistor groove. This design ensures the precise docking and positioning of the wire pins and the resistor pins, ensuring that no offset or incorrect docking occurs during the welding process.

[0039] The roll welding mechanism 2 is arranged between the resistance conveyor belt 11 and the conductor conveyor belt 12 , and the roll welding mechanism 2 includes ultrasonic welding rollers 21 and a welding support 22 which are relatively arranged at upper and lower ends.

[0040] The ultrasonic welding roller 21 uses ultrasonic technology to perform welding, and can complete high-quality welding in a short time, ensuring a firm connection between the resistor pin and the wire pin. The welding support 22 provides stable support to ensure mechanical stability during the ultrasonic welding process.

[0041] In this embodiment, two groups of the wire conveyor belts 12 are arranged in parallel, and the wire pin extension port 122 is arranged on the wire groove 121 close to the resistor conveyor belt 11. The carrier wire arrangement mechanism 3 includes a carrier conveyor belt 31, a carrier material assembly 32 and a carrier box 33. The carrier conveyor belt 31 is arranged between the two groups of wire conveyor belts 12. Since the welded products need to be arranged on the carrier and held with a thermal tape before entering the next glue filling process, and the carrier is located in the middle of the wire, the carrier conveyor belt 31 is arranged between the two groups of wire conveyor belts 12 to facilitate the positioning of the wire and the carrier and the subsequent tape fixation.

[0042] In this embodiment, the outer end of the carrier conveyor belt 31 extending to the middle area of ​​the two sets of wire conveyor belts 12 forms a loading area, the length of the loading area is greater than or equal to the length of the carrier, and the carrier loading assembly 32 and the carrier box 33 are arranged at the side end of the loading area. Since the carrier is located at the lower end of the wire, it cannot be loaded well during the subsequent synchronous transportation of the wire carrier and will be blocked by the wire 6. Therefore, the outer end of the carrier conveyor belt 31 extending to the middle area of ​​the two sets of wire conveyor belts 12 forms a loading area, which means that the carrier has enough space to load without being interfered by the wire, ensuring the smooth operation of the production line. Through this optimization, the automation level of the production line can be improved, production stagnation caused by carrier loading problems can be avoided, and the overall production efficiency can be improved.

[0043] In this embodiment, the plate carrier loading assembly 32 includes a first screw 321 and a walking cylinder 322 arranged on the first screw 321, and a first lifting cylinder 323 is arranged at the lower end of the walking cylinder 322.

The tape roller 41 is responsible for installing the tape, and the tape pressing wheel 42 ensures that the tape can evenly and firmly stick the wire to the carrier. The pneumatic adsorption and pressing component 43 drives the adsorption plate 432 through the third lifting cylinder 431 to adsorb and press the front end of the tape onto the carrier plate to ensure stable tape adhesion; the tape breaking component 44 drives the cutting knife 442 through the fourth lifting cylinder 431 to accurately cut the tape.

[0046] In this embodiment, the third lifting cylinder 431 and the fourth lifting cylinder 441 are fixedly installed on a movable seat 45, and the movable seat 45 is connected to a first screw assembly 46 for controlling its reciprocating movement along the resistance wire conveying direction. It can press the front end of the tape and move synchronously with the wire and the carrier. When the bonding force between the tape and the carrier reaches a certain level, the pressure is cancelled to prevent the tape from loosening.

[0047] In this embodiment, two adhesive tape rollers 41 are disposed opposite to each other on both sides of the conveying direction.

[0048] In this embodiment, the epoxy encapsulation mechanism 7 includes an epoxy resin pool 71, a carrier plate clamping assembly 72, a reciprocating assembly 73 and an encapsulation conveying assembly 74. The carrier plate clamping assembly 72 includes a first mounting seat 721, and the first mounting seat 721 is provided with two mounting plates 722 that can move relatively and a fifth cylinder for controlling the movement of the mounting plates 722. Both ends of the mounting plates 722 are fixedly provided with clamping plates 723 for clamping the carrier plate. The reciprocating assembly 73 includes a second mounting seat 731, and the second mounting seat 731 is installed with a first control motor 732. The output end of the first control motor 732 is connected to a rotating disk 733, and a slider 734 is fixedly provided on the outer periphery of the rotating disk. The slider is slidably connected in a slide groove 736 of a rocker 735, and one end of the rocker 735 rotates The reciprocating assembly 73 also includes a third mounting seat 737, and the third mounting seat is provided with a sixth cylinder for controlling the reciprocating motion of the second mounting seat 731.
