Description

[0002] An automotive temperature sensor is a sensor that senses temperature and converts it into a usable output signal.

[0003] When producing automobile temperature sensors, it is necessary to use welding equipment to weld the wires to the lead positions of the sensors. During the welding process, since the live wire and the neutral wire of the wire need to be separated and then welded to the corresponding lead positions, most of the current welding equipment is manually operated to separate the corresponding lines before welding. It is impossible to automatically transport the sensors and wires, and manual operation is required, which increases production time and cost, resulting in low welding efficiency and poor automation of automobile temperature sensors. In addition, corresponding transportation equipment needs to be designed to transport automobile temperature sensors of various sizes so that the temperature sensors can be automatically transported to the welding position for processing.

[0052] Working principle: When the present invention is used, the live wire and the neutral wire to be welded with the automobile temperature sensor are respectively inserted into the two first delivery tubes 503, and pass through between the two second rotating shafts 505, enter the second delivery tube 504, and as it continues to move, it finally contacts the cutting knife 513;

[0053] Then, the automobile temperature sensor is placed between the two uppermost claws 209 with the welding end in a vertical state by using a tool, and the automobile temperature sensor is supported by the grooves on the two conveying plates 201;

[0054] Then, the first motor 105 is used to drive the first gear 106 to rotate intermittently, and the rotation of the first gear 106 drives the outer gear ring 104 to rotate intermittently, and the rotation of the outer gear ring 104 drives the rotating drum 103 to rotate intermittently for a quarter of a circle, and the rotation of the rotating drum 103 drives the conveying disc 201 to rotate intermittently, so as to transport the automobile temperature sensor located inside the groove on the conveying disc 201. During the rotation of the conveying disc 201, the moving shaft 212 located below the automobile temperature sensor moves around the cam 109, and the ball bearing 215 is used to assist its movement;

[0055] When the moving shaft 212 moves to the protrusion of the cam 109, the moving shaft 212 drives the fixed ring 214 connected to it to move, and compresses the second spring 213. The moving shaft 212 moves and drives the first hinge seat 216 connected to the other end thereof to move. The movement of the first hinge seat 216 drives the first connecting arm 217 to deflect and move. The second hinge seat 218 hingedly connected to the other end of the first connecting arm 217 moves accordingly, and drives the rectangular column 204 to move along the rectangular slide rail 203. The movement of the rectangular column 204 drives the card seat 208 connected to the plug block 206 thereon to move. The movement of the card seat 208 drives the claw 209 to move, so that the two claws 209 can move toward each other when rotating around the center of the conveying disc 201, clamping and fixing the automobile temperature sensor, so that the automobile temperature sensor can be moved to one end of the two circular tubes composed of the two groups of semicircular tubes 312 close to the conveying disc 201.

[0056] The position of the adjustment plug 206 can be adjusted by rotating the fastening screw 207, so that the welding device can be fine-tuned according to the size of the automobile temperature sensor;

[0057] The bidirectional screw 510 is driven to rotate by the third motor 511, so that the bidirectional screw 510 rotates and drives the two knife seats 512 thereon to move away from each other, thereby moving the two cutting knives 513 away from each other, and then the third articulated seat 515 is driven to move by the second electric cylinder 514, and the movement of the third articulated seat 515 drives the second connecting arm 516 connected thereto to deflect and move, thereby driving the push rod 517 connected to the second connecting arm 516 to move along the limiting slide rail 519, and the movement of the push rod 517 drives the pliers 518 thereon to move, so that the pliers 518 on the two push rods 517 can strip the ends of the live wire and the neutral wire;

[0058] Then, the second motor 507 is used to drive the second rotating shaft 505 connected thereto to rotate, and the third gear 520 thereon is driven to rotate, and the third gears 520 on the two second rotating shafts 505 are meshed with each other to make the two second rotating shafts 505 rotate in opposite directions, thereby driving the live wire and the neutral wire to move, so that the live wire and the neutral wire continue to move and are inserted into the two round tubes composed of the two groups of semicircular tubes 312, and finally come to the welding end of the automobile temperature sensor and contact the welding end of the automobile temperature sensor. At this time, the third motor 511 is used to rotate in the opposite direction again, so that the cutting knife 513 can cut the live wire and the neutral wire between the second conveying pipe 504 and the two round tubes composed of the two groups of semicircular tubes 312, and then laser welding is performed using the laser welding device 4;

[0059] After welding is completed, the first electric cylinder 307 is used to drive the rack 308 to move, and the rack 308 moves to drive the second gear 304 to rotate. The second gear 304 rotates to drive the turntable 305 to rotate, and the turntable 305 rotates to drive the cylinder 306 to rotate in a circle. The two cylinders 306 rotate in a circle and drive the movable bracket 311 on the outside to move accordingly, so that the two movable brackets 311 move away from each other, and the two movable brackets 311 move away from each other to drive the semicircular tubes 312 thereon to move, so that the two circular tubes composed of two groups of semicircular tubes 312 are separated, so that the live wire and the neutral wire inside them fall off, and then the conveyor disc 201 continues to rotate to drive the automobile temperature sensor to move accordingly, and the movable shaft 212 where the automobile temperature sensor is located moves away from the protrusion of the cam 109, and then the movable shaft 212 is reset under the elastic force of the second spring 213, so that the claw 209 no longer clamps the automobile temperature sensor, and then the automobile temperature sensor after welding falls onto the conveyor line below and is transported away by the conveyor belt.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
