The lead pin of NTC thermistor is Dumet wire with diameter below 0.3m/m, which is made of Ni-Fe alloy and plated with copper, and is commonly used in diode or bulb (tube) industry. The Dumet wire belongs to the nickel-iron alloy class, has small wire diameter and very small expansion coefficient, is different from a common CU or CP lead, and has great influence on the product percent of pass due to insufficient straightness of the wire, so the Dumet wire is very troublesome in the straightening processing process.

In addition, the glass-packaged temperature sensor is completed by welding equal-length dumet wires with silver paste on the upper part and the lower part of a chip respectively and then carrying out glass sealing on the dumet wires and a glass tube, and the chip is small in size (the length is about 4mm by 4mm) due to the fact that the wires are thinner by 0.3m/m, and therefore high precision needs to be guaranteed in the production process.

In the process of bonding the chip, the front side and the back side of the chip with the length and the width of several millimeters are required to be welded with Dumet wires, and the conventional equipment does not provide a foundation.

In addition, how to perfectly fuse the cylindrical glass shell with the internal chip and the Dumet wire after the glass shell is inserted and ensure that the cylindrical glass shell is in an elliptical shape cannot be realized by the existing equipment.

In the forming process of the system of straightening, cutting, dipping silver, welding a chip, baking silver, inserting a glass tube and forming at high temperature, the prior art does not provide a better scheme for reference.

Under normal conditions, when the second stretching cylinder 33-39 is not operated, the fourth spring 33-43 applies force to the extrusion sliding plate 33-42, and the lower end of the X structure is in an open state. When the second stretching air cylinder 33-39 contracts, the whole X structure is driven to move upwards through the U-shaped rod 33-38. Because the inner sides of the two limit baffles 33-41 are provided with the inclined planes, the inclined planes incline upwards towards the left clamping hand 33-36 and the right clamping hand 33-37, so that the lower ends of the left clamping hand 33-36 and the right clamping hand 33-37 are extruded and closed when moving upwards, and clamping can be realized.

2) The first stretching cylinder 33-11 extends out, one side of the first lever 33-13 close to the shearing slide rail 33-6 is pressed downwards, the lower fixed clamping plate 33-7 is lifted, the crank transmission mechanism 33-4 drives the shearing transmission sliding seat 33-5 to move backwards, and because the upper movable clamping plate 33-8 is lifted, the Dumet wire is only supported by the lower fixed clamping plate 33-7 and does not move back and forth; meanwhile, when the first lever 33-13 is pressed down close to one side of the shearing slide rail 33-6, the cutting slide seat 33-15 is slightly moved down, the pressing block 33-18 and the cutting knife 33-19 are slightly moved down, the Dumet wire 21 is cut, the mechanical hand 33-23 is loosened, and the cut Dumet wire 21 freely falls down due to the fact that gaps exist on one side of the horizontal cutting plate 33-35 and the balance plate 33-20, falls into the jig groove 13-2 of the transfer jig 13, and the jig groove 13-2 is intermittently and equidistantly shifted by the shifting rod of the first transfer jig conveying mechanism 9, so that the fallen Dumet wire 21 can be continuously received.

The above operations are repeated until all the dumet wires 21 are cut.

As shown in fig. 25 to 26, the lengths of the dumet wires 21 after cutting are different from each other, and therefore, the transfer jig 13 carrying the dumet wires 21 needs to be cut in order while being conveyed forward on the conveying platform 1 by the first transfer jig conveying mechanism 9. Specifically, a first limit baffle 23 is arranged on one side of the conveying platform 1, one end, close to the crank conveying mechanism 33-4, of the first limit baffle 23 is in an arc-shaped opening state, and the other end of the first limit baffle 23 is in a vertical plate shape, so that the cut Dumet wire 21 is gradually limited by the first limit baffle 23 and one end of the Dumet wire is kept to be aligned straightly.

The front and the back of the lower end of the mounting block 24-5 are respectively provided with a pressing block 24-6 and a cutting knife 24-7. The cutting knife 24-6 passes through the perforation on the supporting seat 24-3 of the second cutting mechanism to be opposite to the cutting plate (the cutting knife can be guided to move up and down through the perforation). In addition, a jacking spring 24-8 is sleeved between the mounting block 24-5 and the horizontal part of the second cutting mechanism supporting seat 24-3 on the cutting knife 24-7.

An infrared probe is arranged on one side of the cutting knife 24-7 and is used for detecting whether the Dumet wire 21 passes through or not.

In a non-working state, the second cutting mechanism lifting cylinder 24-1 is in a contraction state, the front end of the second cutting mechanism lever 24-2 is raised to a certain height, and the front end of the mounting block 24-5 is connected with the second cutting mechanism lever 24-2 through a spring, and the lower end of the mounting block is also raised upwards through a jacking spring 24-8, so that a certain distance exists between the pressing block 24-6, the cutting knife 24-7 and a cutting plate at the lower end; when the Dumet wire 21 passes through, after corresponding information is detected through the infrared probe, the second cutting mechanism lifting cylinder 24-1 extends out, the front end of the second cutting mechanism lever 24-2 descends, the second cutting mechanism ejector rod 24-4 presses the mounting block 24-5 downwards, the cutting knife 24-7 penetrates through a through hole in the second cutting mechanism supporting seat 24-3, so that the mounting block 24-5, the pressing block 24-6 and the cutting knife 24-7 integrally move downwards in a straight line, finally the pressing block 24-6 and the cutting knife 24-7 fall on the cutting plate, the pressing block 24-6 presses the Dumet wire 21, the cutting knife 24-7 cuts the Dumet wire 21, after cutting, the second cutting mechanism lifting cylinder 24-1 contracts, and the mounting block 24-5, the mounting block 24-5 and the cutting knife under the action of the jacking spring 24-8, The pressing block 24-6 and the cutting knife 24-7 automatically reset. Here, after the second cutting mechanism 24 performs the cutting, both ends of the dumet wire 21 on the transfer jig 13 are flush with each other.

After the transfer jig 13 continues to be conveyed forward, the dumet wire 21 completes the dispensing operation, specifically, the dispensing operation is completed by the silver dipping mechanism 4.

As shown in fig. 27, the silver dipping mechanism 4 comprises a silver paste pump 4-3, wherein the silver paste pump 4-3 is a screw pump, and a silver paste notch 4-8 is arranged at a proper position at the upper end of the shell of the screw pump. The spiral pump is connected with a silver pumping motor 4-5 through a belt conveying mechanism 4-4. The screw pump is driven to rotate by the motor. The right end of the screw pump is provided with a liquid outlet, one end of the flow tube 4-6 is connected with the liquid outlet, the other end of the flow tube 4-6 is fixedly arranged at the top end of the supporting plate 4-7, and the lower end of the outlet of the flow tube 4-6 is opposite to the silver paste gap 4-8 at the upper end of the silver paste pump 4-3.

And the chip enters the chip positioning groove 5-5 after passing through the U-shaped groove at the top end of the chip feeding vibration disc 5-4, and the U-shaped groove is arranged at the transition part between the top end of the spiral channel and the chip positioning groove 5-5, so that the width of the U-shaped groove is only used for a single square chip to pass through. Therefore, the regularly arranged square chips can enter the chip positioning grooves 5-5 through the U-shaped grooves, and the irregularly arranged square chips fall back to the chip feeding vibration disc 5-4 again. And one side of the chip positioning groove 5-5 is provided with a corresponding vibrating motor, and the discharging and feeding of the square chip can be promoted through the vibrating motor.

The feeding time of the chip feeding vibration disc 5-4 is the same as the time of the first transfer tool conveying mechanism 9 for conveying the transfer tool 13. That is, when the transferring jig 13 is shifted by the first transferring jig conveying mechanism 9, the chip feeding vibration disc 5-4 feeds materials into the chip positioning groove 5-5, and when the transferring jig 13 stops, the chip feeding vibration disc 5-4 stops feeding materials.

The bottom end of the vacuum suction plate 5-10 is provided with a groove which is matched with the Dumet wire 21 and is communicated with the hollow space inside the vacuum suction plate 5-10. The inner hollow space is connected to a vacuum pump 5-11 via a pipe.

Meanwhile, the supporting plates 5-8 of the lifting mechanism move downwards and fall below the transferring jig 13.

3) The shifting jig 13 moves forwards at the intervals of the four jig grooves 13-2 and stops, and the supporting plate 5-8 of the lifting mechanism is lifted. Meanwhile, the vacuum suction plate 5-10 sucks a dumet wire stuck with a chip to move back to the position a in an inclined mode (the vacuum suction plate 5-10 corresponds to the position IIII in the figure 34), then the vacuum suction plate moves downwards to place the dumet wire stuck with the chip on the dumet wire of the position a again (the vacuum suction plate 5-10 corresponds to the position I in the figure 34), and the two dumet wires are bonded with the chip. Then, the Dumet wire is translated to a station b (the vacuum suction plate 5-10 corresponds to a position II in the figure 34), the Dumet wire adsorbing the station b moves upwards to the front to continuously remove the chip at the end of the chip positioning groove 5-5 (the chip interval is conveyed forwards) (the vacuum suction plate 5-10 corresponds to a position III in the figure 34).

At the moment, a Dumet wire d which is just adhered with a chip is adsorbed on the vacuum suction plate 5-10, the Dumet wire d is opposite to a Dumet wire e which is not adhered with a chip below, and the controller controls and drives the three-axis adjusting mechanism 5-9, so that after the vacuum suction plate 5-10 moves downwards for a certain distance, the vacuum suction plate 5-10 releases the Dumet wire d, and at the moment. And the Dumet wire d with the chip is superposed on the Dumet wire e, and the Dumet wire e is adhered with silver paste, so that the chip on the Dumet wire d and the Dumet wire e are also adhered together, and the welding of the two Dumet wires and the chip is completed.

2) After the vacuum suction plate 5-10 is released, the vacuum suction plate is translated to the station b, then moves downwards to finish sucking the Dumet wire f at the position b, and after finishing the action, the vacuum suction plate is lifted and moves forwards vertically, and moves to the end of the chip positioning groove 5-5 to glue the chip. Meanwhile, the supporting plates 5-8 of the lifting mechanism move downwards and fall below the transferring jig 13.

3) The shifting jig 13 moves forwards at the intervals of the four jig grooves 13-2 and stops, and the supporting plate 5-8 of the lifting mechanism is lifted. Meanwhile, the vacuum suction plate 5-10 absorbs a Dumet wire stuck with a chip to obliquely move back to the position a, and then moves downwards to place the Dumet wire stuck with the chip on the Dumet wire of the position a again, so that the two Dumet wires are bonded with the chip. Then the Dumet wire is translated to a station b, the Dumet wire at the station b is adsorbed, then the Dumet wire moves upwards, and the Dumet wire is continuously removed from the end of the chip positioning groove 5-5 (the chips are conveyed forwards at intervals). Meanwhile, the supporting plates 5-8 of the lifting mechanism move downwards and fall below the transferring jig 13.

4) And the steps 1) to 3) are repeated in a circulating way, so that the situation of D section in fig. 35 is formed, namely, the formed semi-finished products are arranged in the jig groove 13-2 at intervals as shown in fig. 28.
