Description

Technical Field

[0001] The present invention belongs to the technical field of sensors, and particularly relates to a combined temperature sensor based on a split design and a combined production process. Background Art

[0002] During the use of a cabinet, to ensure the efficient use of the cabinet, it is necessary to monitor the temperature inside the cabinet in real time for timely emergency handling. In the prior art, usually one temperature controller is used for 8 cabinets. Since the cabinets are large and are arranged in rows of 8 in the computer room, 8 sensors with different lengths need to be connected to 8 cabinets.

[0003] However, the above-mentioned sensor installation method not only causes cumbersome wiring and is not conducive to the efficient installation of sensors, but also there may be a situation where the sensors are inserted in the wrong positions. At the same time, due to the different wire resistances caused by the different lengths of each sensor, under the influence of the wire resistance, the error of temperature monitoring is relatively large, thus affecting the accuracy of the temperature monitoring data in each cabinet. Therefore, we provide a combined temperature sensor based on a split design and a combined production process to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a combined temperature sensor based on a split design and a combined production process. Through the specific structural design of a rotation positioning mechanism, a traction conveying mechanism, a docking control mechanism, and a support mechanism, the problems in the above background art are solved.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention relates to a combined temperature sensor based on a split design, comprising a first sensor, a second sensor, a sensor connecting wire, and a main board connecting wire. Among them, the first sensor includes a signal core wire, one end of which is connected to a resistor mounting portion, and the other end is connected to an RJ50 female socket. The second sensor includes a signal core wire, both ends of which are connected to RJ50 female sockets, and the peripheral side of the signal core wire is connected to a resistor mounting portion. An NTC thermistor is installed inside the resistor mounting portion. Marking sleeves are sleeved and installed on the signal core wires of the first sensor and the second sensor. The sensor connecting wire includes a signal core wire, both ends of which are connected to RJ50 crystal heads. The main board connecting wire includes a signal core wire, one end of which is connected to an RJ50 female socket, and the other end is connected to a main board plug-in component. The RJ50 female socket on the first sensor is inserted and matched with the RJ50 crystal head on the corresponding sensor connecting wire. The RJ50 female sockets on the second sensor are inserted and matched with the RJ50 crystal heads on the sensor connecting wires on both sides of it. The RJ50 female socket on the main board connecting wire is inserted and matched with the RJ50 crystal head on the corresponding sensor connecting wire.

[0007] The combined production process based on the above combined temperature sensor includes the following steps:

[0008] S01. Install the second sensor and the sensor connecting wire inside the rotary positioning mechanism respectively, and arrange each second sensor and the sensor connecting wire along the circumferential direction, with intervals between the second sensor and the sensor connecting wire.

[0009] S02. Place the first sensor on the top of the traction conveying mechanism, and clamp and fix the RJ50 female socket at the front end of the first sensor. A docking control mechanism is installed on the traction conveying mechanism. The RJ50 female socket at the front end of the first sensor is aligned with the RJ50 crystal head on the lowermost sensor connecting wire on the rotary positioning mechanism.

[0010] S03. Release the clamping and fixing of the lowermost sensor connecting wire on the rotary positioning mechanism, and control the docking control seat to move along the axial direction, so that the first docking frame on the docking control seat moves to the inside of the rotary positioning mechanism. Then control the first docking frame to move downward until it touches the signal core wire of the sensor connecting wire below it. Subsequently, drive the first docking frame to move outward from the rotary positioning mechanism through the docking control seat, so that the RJ50 crystal head on the lowermost sensor connecting wire is inserted and matched with the RJ50 female socket at the front end of the first sensor.

[0011] S04. After controlling the first docking frame to move upward and reset, drive the docking control seat back to its initial position. Then, release the clamping and fixing of the RJ50 female socket at the front end of the first sensor, and make the first sensor disengage from the traction and conveying mechanism. The sensor connecting wire plugged thereon moves to the top of the traction and conveying mechanism. Then, control the second docking frame on the docking control seat to move downward until it touches the signal core wire of the sensor connecting wire below it.

[0012] S05. Control the rotation positioning mechanism to rotate so that the second sensor at the next position moves to the lowermost position. Then, control the docking control seat to move along the axis again, so that the second docking frame on the docking control seat moves towards the inner side of the rotation positioning mechanism. During this process, push the RJ50 crystal head on the sensor connecting wire below it through the second docking frame until the RJ50 crystal head completes the plugging with the RJ50 female socket on the lowermost second sensor.

[0013] S06. After controlling the second docking frame to move upward and reset, drive the docking control seat back to its initial position. Then, release the clamping and fixing of the lowermost second sensor, and make the sensor connecting wire disengage from the traction and conveying mechanism. The second sensor plugged thereon moves to the top of the traction and conveying mechanism, and clamp and fix the RJ50 female socket at the front end of the second sensor.

[0014] S07. Control the rotation positioning mechanism to rotate again so that the sensor connecting wire at the next position moves to the lowermost position. Repeat steps S03 to S04 to realize the plugging of the lowermost sensor connecting wire with the second sensor at the top of the traction and conveying mechanism again. Repeat steps S05 to S06 to realize the plugging of the lowermost second sensor with the sensor connecting wire at the top of the traction and conveying mechanism again.

[0022] The present invention has the following beneficial effects:

[0023] 1. In the present invention, a complete temperature sensor is designed as a combined sensor composed of a first sensor, a second sensor, a sensor connecting wire and a main board connecting wire, and marking sleeves with different colors are installed on the first sensor and the second sensor, which effectively avoids the reduction of the installation efficiency caused by the wrong installation position of the sensor. At the same time, the lengths of the first sensor, the second sensor and the sensor connecting wire are designed to be the same, which can ensure that the wire resistances of the three are the same, and is beneficial to ensuring the accuracy of the temperature detected by the sensor.

[0024] 2. After moving the sensor connecting wire after completion of plugging to the top of the traction and conveying mechanism, the present invention first controls the second electromagnet to be energized and magnetized so that the moving frame moves to fit against one side of the first fixing frame, and drives the inclined surface stress seat to move upward to a specified position through the moving inclined surface pushing seat. At this time, the RJ50 crystal head at the front end of the sensor connecting wire on the first fixing frame and the RJ50 female seat on the lowermost second sensor are at the same height, so as to ensure that the horizontal movement of the RJ50 crystal head at this position can be smoothly plugged with the RJ50 female seat. After the sensor connecting wire on the first fixing frame is plugged with the corresponding second sensor, the just-plugged second sensor is pulled to move onto the first fixing frame, and then the second electromagnet is controlled to be powered off and demagnetized so that the first fixing frame moves downward to return to the initial position.

[0025] 3. When the present invention controls the rotation of the rotary positioning mechanism to rotate by half of the angle between two adjacent positioning components, during this process, the rotation of the transposition gear ring drives the traction conveying gear to rotate. The reciprocating lead screw that rotates synchronously with the traction conveying gear drives the traction conveying frame to drive the inserted sensor component to move. As a result, the RJ50 crystal head or RJ50 female socket at the front end of the sensor component just moves between the two end clamping parts. Subsequently, the clamping and fixing of the signal core wire by the core wire clamping part is released. Then, continue to control the rotation of the rotary positioning mechanism to rotate by half of the angle between two adjacent positioning components. At this time, the second sensor or the sensor connecting wire at the next position rotates to the lowest position, and the rotation of the reciprocating lead screw drives the traction conveying frame back to the initial position. In this way, the traction and conveying of the sensor component during the production process of the combined sensor are realized, which is beneficial to improving the production efficiency of the sensor combination.

[0026] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The sensor connecting wire 9 includes a signal core wire 11, and both ends of the signal core wire 11 are connected with RJ50 crystal heads 15; the main board connecting wire 10 includes a signal core wire 11, one end of the signal core wire 11 is connected with an RJ50 female socket 13, and the other end of the signal core wire 11 is connected with a main board plug-in part 16; the RJ50 female socket 13 on the first sensor 7 is in plug-in fit with the RJ50 crystal head 15 on the corresponding sensor connecting wire 9, the RJ50 female sockets 13 on the second sensor 8 are in plug-in fit with the RJ50 crystal heads 15 on the sensor connecting wires 9 on both sides thereof, and the RJ50 female socket 13 on the main board connecting wire 10 is in plug-in fit with the RJ50 crystal head 15 on the corresponding sensor connecting wire 9;

[0047] Based on the above combined production process of the combined temperature sensor, it includes the following steps:

[0048] S01. Install the second sensor 8 and the sensor connecting wire 9 inside the rotary positioning mechanism 1 respectively, and make each second sensor 8 and the sensor connecting wire 9 be arranged along the circumferential direction, with intervals between the second sensor 8 and the sensor connecting wire 9, as Figure 3 shown;

[0049] S02. Place the first sensor 7 on the top of the traction conveying mechanism 2, and clamp and fix the RJ50 female socket 13 at the front end of the first sensor 7. A docking control mechanism 3 is installed on the traction conveying mechanism 2, and the RJ50 female socket 13 at the front end of the first sensor 7 is aligned with the RJ50 crystal head 15 on the lowermost sensor connecting wire 9 on the rotary positioning mechanism 1;

[0050] S03, release the clamping and fixing of the lowest sensor connection line 9 on the rotation positioning mechanism 1, and control the docking control seat 303 to move along the axial direction, so that the first docking frame 306 on the docking control seat 303 moves to the inside of the rotation positioning mechanism 1, and then control the first docking frame 306 to move downward (through the action of magnetic attraction) until it contacts the signal core line 11 of the sensor connection line 9 below it, and then drive the first docking frame 306 to move to the outside of the rotation positioning mechanism 1 through the docking control seat 303, so that the RJ50 crystal head 15 on the lowest sensor connection line 9 is plugged into the RJ50 female socket 13 at the front end of the first sensor 7 (the RJ50 crystal head 15 and the RJ50 female socket 13 are at the same height to ensure that the two can be plugged smoothly);

[0051] S04, after controlling the first docking frame 306 to move upward and reset, the docking control seat 303 is driven back to the initial position, and then the clamping and fixing of the RJ50 female socket 13 at the front end of the first sensor 7 is released, and the first sensor 7 is separated from the traction conveying mechanism 2 (through traction force), and the sensor connecting line 9 plugged thereon moves to the top of the traction conveying mechanism 2, and then the second docking frame 307 on the docking control seat 303 is controlled to move downward (through magnetic attraction) until it contacts the signal core line 11 of the sensor connecting line 9 below it;

[0052] S05, control the rotary positioning mechanism 1 to rotate so that the second sensor 8 at the next position moves to the lowest position (according to Figure 4 The second docking frame 307 on the docking control seat 303 moves toward the inner side of the rotation positioning mechanism 1. In this process, the second docking frame 307 pushes the RJ50 crystal head 15 on the sensor connecting line 9 below it until the RJ50 crystal head 15 is plugged into the RJ50 female socket 13 on the second sensor 8 at the bottom (because the second sensor 8 at the bottom is still in a clamping state at this time, it can ensure that the RJ50 female socket 13 at this position can be smoothly plugged into the RJ50 crystal head 15 horizontally);

[0053] S06, after controlling the second docking frame 307 to move upward and reset, the docking control seat 303 is driven back to the initial position, and then the clamping and fixing of the second sensor 8 at the bottom is released, and the sensor connecting line 9 is separated from the traction conveying mechanism 2, and the second sensor 8 plugged thereon is moved to the top of the traction conveying mechanism 2, and the RJ50 female socket 13 at the front end of the second sensor 8 is clamped and fixed;

[0054] S07. Control the rotation positioning mechanism 1 to rotate again so that the sensor connection line 9 at the next position moves to the lowermost position. Loop through steps S03 to S04 to achieve the insertion of the lowermost sensor connection line 9 into the second sensor 8 at the top of the traction and conveying mechanism 2 again. Loop through steps S05 to S06 to achieve the insertion of the lowermost second sensor 8 into the sensor connection line 9 at the top of the traction and conveying mechanism 2 again. In this way, the assembly of the entire combined temperature sensor is achieved.

[0055] Specific Embodiment 2. On the basis of Specific Embodiment 1, the rotation positioning mechanism 1 includes a rotation and bearing assembly 4. Among them, the rotation and bearing assembly 4 includes a rotation and bearing ring 401. An indexing gear ring 402 coaxial with it is fixedly arranged on the outer wall of the rotation and bearing ring 401. A number of positioning assemblies 5 are arrayedly installed on the inner wall of the rotation and bearing ring 401. The positioning assemblies 5 are used to install and fix each second sensor 8 and sensor connection line 9.

[0056] The positioning assembly 5 includes an axial positioning frame 501 fixedly installed on the inner wall of the rotation and bearing ring 401. End mounting frames 502 are fixedly arranged on both opposite sides of the axial positioning frame 501. A positioning control shaft 503 is rotatably arranged inside one of the end mounting frames 502. A guide rod 504 is fixedly arranged inside the other end mounting frame 502. The positioning control shaft 503 is connected to the output end of a positioning control motor 505 installed on its corresponding end mounting frame 502. By rotating the rotation and bearing ring 401, the common rotation of each second sensor 8 and sensor connection line 9 installed thereon can be achieved. Thus, the switching of the second sensor 8 or sensor connection line 9 at the lowermost position (i.e., the corresponding position of the traction and conveying mechanism 2) of the rotation and bearing ring 401 is achieved.

[0057] In this embodiment of the present invention, two device positioning parts 506 are symmetrically and slidably arranged inside the end mounting frame 502. The positioning control shaft 503 is in threaded cooperation with the corresponding two device positioning parts 506, and the guide rod 504 is in sliding cooperation with the corresponding two device positioning parts 506. A driving worm 507 is fixedly installed on the circumferential surface of the positioning control shaft 503, and a driving toothed plate 508 is fixedly arranged on the surface of the device positioning part 506 on the guide rod 504; a linkage shaft 509 is rotatably arranged inside the axial positioning frame 501. One end of the linkage shaft 509 is fixedly provided with a driving turbine 510 that meshes and drives with the driving worm 507, and the other end of the linkage shaft 509 is fixedly provided with a driving gear 511, and the driving gear 511 meshes with the driving toothed plates 508 on both sides thereof; through the above specific structural design, after placing a second sensor 8 or a sensor connecting wire 9 on the positioning assembly 5 (i.e., between the respective device positioning parts 506), the controller controls the positioning control motor 505 to start and drive the positioning control shaft 503 to rotate. The rotation of the driving worm 507 drives the rotation of the driving turbine 510, and then the rotation of the linkage shaft 509 drives the driving gear 511 to rotate. Under the meshing action of the driving gear 511 and the driving toothed plate 508, the two driving toothed plates 508 approach each other, thereby simultaneously driving the respective device positioning parts 506 to approach each other to complete the clamping and fixing of the second sensor 8 or the sensor connecting wire 9 (the clamping and fixing of the second sensor 8 or the sensor connecting wire 9 can be released by reverse operation). In this way, the installation and fixing of a number of second sensors 8 and sensor connecting wires 9 on the rotary bearing assembly 4 are realized.

[0058] In this embodiment of the present invention, the rotary positioning mechanism 1 is arranged on a support mechanism 6. The support mechanism 6 includes a support frame 601, and the support frame 601 is installed on a reciprocating moving seat. A lifting hydraulic cylinder connected to the support frame 601 is installed on the reciprocating moving seat, and the reciprocating movement of the reciprocating moving seat can be realized by a horizontal hydraulic cylinder. After the combined production of the combined sensor corresponding to one rotary positioning mechanism 1 is completed, first, the lifting hydraulic cylinder is used to drive the support frame 601 to move upward, and then the horizontal hydraulic cylinder is used to drive the support frame 601 to move, so as to move the next fully loaded rotary positioning mechanism 1 to the combination station (i.e., the corresponding position of the traction conveying mechanism 2). Then, the lifting hydraulic cylinder is used to drive the support frame 601 to descend to the original height. At this time, the switching gear ring 402 realizes meshing with the traction conveying gear 216 below it. During the continuous production process of the combined sensor, the second sensor 8 and the sensor connecting wire 9 are clamped and installed on the empty rotary positioning mechanism 1 again. Two support rings 602 are fixedly arranged on the support frame 601, and one rotary positioning mechanism 1 is installed on each group of support rings 602 (such as Figure 2As shown in the figure, the rotating bearing ring 401 is rotatably connected to the corresponding support ring 602. A commutation motor 603 corresponding to the rotation positioning mechanism 1 is installed on the support frame 601. The output shaft of the commutation motor 603 is connected to a commutation gear 604 that meshes with the corresponding commutation gear ring 402. By controlling the rotation of the corresponding commutation gear 604 by the commutation motor 603, under the meshing action of the commutation gear 604 and the commutation gear ring 402, the rotation of the corresponding rotation positioning mechanism 1 can be realized, and the angle of each rotation of the rotation positioning mechanism 1 is fixed and unchanged.

[0059] In this embodiment of the present invention, the docking control mechanism 3 includes a first fixing frame 301. A second fixing frame 302 is fixedly arranged at the top of the first fixing frame 301. A docking control seat 303 is slidably arranged at the top of the second fixing frame 302. A movable plate 304 is fixedly arranged on one side of the docking control seat 303. The output end of a telescopic cylinder 305 installed on the second fixing frame 302 is connected to the movable plate 304. The reciprocating movement of the docking control seat 303 can be controlled by the telescopic cylinder 305. A first docking frame 306 and a second docking frame 307 are respectively slidably arranged longitudinally on the docking control seat 303. A semi-circular pushing tube 308 located below the docking control seat 303 is fixedly arranged on the surface of the second docking frame 307. A first elastic member 309 and a first electromagnet 310 are respectively arranged at the top of the docking control seat 303. The first docking frame 306 and the second docking frame 307 are respectively connected to the corresponding first elastic member 309. First permanent magnets that are magnetically attracted to the first electromagnet 310 are arranged on both the first docking frame 306 and the second docking frame 307. In the initial state, each first elastic member 309 positions the first docking frame 306 and the second docking frame 307 at the highest position, and each first electromagnet 310 is in a power-off and demagnetized state.

[0060] After releasing the clamping and fixing of the lowermost sensor connecting wire 9 on the rotation positioning mechanism 1, the telescopic cylinder 305 is used to control the movement of the docking control seat 303 along the axial direction, so that the first docking frame 306 on the docking control seat 303 moves to the inside of the rotation positioning mechanism 1. Then, the first electromagnet 310 at the position of the first docking frame 306 is controlled to be energized and magnetized to move it downward (during this process, the first elastic member 309 is compressed) until the limiting port at the bottom of the first docking frame 306 abuts against the signal core wire 11 of the sensor connecting wire 9 below it. Subsequently, the telescopic cylinder 305 is used to control the docking control seat 303 to drive the first docking frame 306 to move outward from the rotation positioning mechanism 1, and the first docking frame 306 is used to push the RJ50 crystal head 15 on the lowermost sensor connecting wire 9 to move outward from the rotation positioning mechanism 1, so that the RJ50 crystal head 15 is inserted into the RJ50 female seat 13 at the front end of the first sensor 7 or the second sensor 8. Then, the first docking frame 306 is controlled to move upward and reset, and then the docking control seat 303 is driven back to the initial position.

[0061] After the sensor connecting wire 9 that has been plugged in is towed and moved to the top of the towing and conveying mechanism 2, the first electromagnet 310 at the position of the second docking frame 307 is controlled to be energized and magnetized to move downward (during this process, the first elastic member 309 is compressed), until the limiting port at the bottom of the second docking frame 307 abuts against the signal core wire 11 of the sensor connecting wire 9 below it. Then, the docking control seat 303 is controlled to move along the axial direction, so that the second docking frame 307 on the docking control seat 303 moves towards the inner side of the rotation positioning mechanism 1. During this process, the RJ50 crystal head 15 on the sensor connecting wire 9 below it is pushed by the second docking frame 307 (specifically, the semi-circular pushing tube 308 on the second docking frame 307) until the RJ50 crystal head 15 is plugged into the RJ50 female socket 13 on the lowermost second sensor 8.

[0062] In this embodiment of the present invention, a U-shaped mounting frame 311 is fitted to the bottom of the first fixing frame 301. A moving rod is horizontally slidably arranged on the U-shaped mounting frame 311. One end of the moving rod is fixedly provided with a moving frame 312 located inside the U-shaped mounting frame 311, and the other end of the moving rod is fixedly provided with a magnetic plate 313 located outside the U-shaped mounting frame 311. The second electromagnet mounted on the surface of the U-shaped mounting frame 311 is magnetically attracted to the second permanent magnet on the magnetic plate 313. A second elastic member connected to the moving frame 312 is arranged on the inner wall of the U-shaped mounting frame 311. A slope stress seat 314 is fixedly provided at the bottom of the first fixing frame 301. A slope pushing seat 315 that fits with the slope stress seat 314 is fixedly provided on one side of the moving frame 312. In the initial state, the second elastic member is in a natural state, and the second electromagnet is in a power-off and demagnetized state. At this time, the first fixing frame 301 is fitted to the U-shaped mounting frame 311, and the slope pushing seat 315 is in contact with the slope stress seat 314. After controlling the second electromagnet to be energized and magnetized, the magnetic plate 313 is moved by the strong magnetic attraction force to fit on the surface of the U-shaped mounting frame 311, and the moving frame 312 is moved to fit on one side of the first fixing frame 301. The slope stress seat 314 is driven by the moving slope pushing seat 315 to move upward a certain distance (a small amplitude), thereby realizing the lifting of the entire first fixing frame 301;

[0063] Specifically, after the sensor connecting line 9 after the plugging is moved to the top of the traction and conveying mechanism 2, the second electromagnet is first controlled to be energized and magnetized so that the movable frame 312 moves to fit on one side of the first fixed frame 301, and the inclined surface force bearing seat 314 is driven to move upward to the specified position through the moving inclined surface pushing seat 315. At this time, the RJ50 crystal head 15 at the front end of the sensor connecting line 9 on the first fixed frame 301 is at the same height as the RJ50 socket 13 on the second sensor 8 at the bottom, so as to ensure that the horizontal movement of the RJ50 crystal head 15 at this position can smoothly complete the plugging with the RJ50 socket 13. After completing the plugging of the sensor connecting line 9 on the first fixed frame 301 and the corresponding second sensor 8, the second sensor 8 that has just been plugged is pulled to move to the first fixed frame 301, and then the second electromagnet is controlled to be powered off and demagnetized so that the first fixed frame 301 moves downward back to the initial position (that is, the first fixed frame 301 is fitted on the U-shaped mounting frame 311).

[0064] In this embodiment of the present invention, the traction conveying mechanism 2 includes a horizontal mounting frame 201, a horizontal guide platform 202 is fixedly arranged on the top of the horizontal mounting frame 201, and each sensor component after plug-in matching is transported along the horizontal guide platform 202 under the action of traction force, and the U-shaped mounting frame 311 is fixedly arranged at the bottom of the horizontal mounting frame 201, and a traction conveying frame 203 is sleeved on the horizontal mounting frame 201. A horizontal limiting rod 204 that is slidably matched with the top of the horizontal guide platform 202 is fixedly arranged on one side of the traction conveying frame 203 (the horizontal limiting rod 204 will not be separated from the traction conveying frame 203 during the entire traction process, thereby realizing the traction conveying The conveying frame 203 is provided with two core wire clamping parts 205 symmetrically and slidably inside the traction conveying frame 203. The output end of the first clamping motor 206 installed outside the traction conveying frame 203 is connected with a first bidirectional screw. The first bidirectional screw is threadedly matched with the core wire clamping part 205 sleeved thereon. When the first bidirectional screw is controlled to rotate by the first clamping motor 206, the two core wire clamping parts 205 can be driven to approach each other until the signal core wire 11 at the corresponding position is clamped and fixed. Then, the traction conveying frame 203 is controlled to move horizontally toward the horizontal material guide table 202, so as to realize the traction movement of the sensor component after the plug-in mating is completed.

[0065] On the top of the horizontal mounting bracket 201, two vertical mounting plates 207 are symmetrically and fixedly arranged. Between the vertical mounting plates 207, a second double-headed screw 208 is rotatably arranged. On the top of the horizontal mounting bracket 201, two moving plates 209 are symmetrically and slidably arranged. The second double-headed screw 208 is in threaded cooperation with the moving plates 209 sleeved thereon. At the end of the horizontal support rod 210 fixedly arranged on the moving plate 209, a terminal clamping part 211 is fixed. The second double-headed screw 208 is connected to the output end of a second clamping motor 212 installed on one of the vertical mounting plates 207. After the RJ50 female socket 13 is towed and moved between the two terminal clamping parts 211, by controlling the second double-headed screw 208 to rotate through the second clamping motor 212, the two relatively arranged moving plates 209 can be driven to approach each other until the two terminal clamping parts 211 tightly clamp on both sides of the RJ50 female socket 13. Thus, the position fixation of the RJ50 female socket 13 at this position is realized. Subsequently, the clamping fixation of the lowermost sensor connecting wire 9 on the rotation positioning mechanism 1 is released, and the docking control seat 303 is controlled to move along the axial direction, so that the first docking frame 306 on the docking control seat 303 moves to the inside of the rotation positioning mechanism 1. Then, the first docking frame 306 is controlled to move downward (that is, the first electromagnet 310 at the position of the first docking frame 306 is energized to generate magnetism, and under the action of magnetic attraction, the first docking frame 306 moves downward) until it abuts against the signal core wire 11 of the sensor connecting wire 9 below it. Subsequently, the docking control seat 303 drives the first docking frame 306 to move outward from the rotation positioning mechanism 1, so that the RJ50 crystal head 15 on the lowermost sensor connecting wire 9 is inserted into the RJ50 female socket 13 between the two terminal clamping parts 211;

[0066] On the top of the horizontal mounting bracket 201, two lateral baffles 213 are symmetrically and fixedly arranged. The lateral baffles 213 are attached to both sides of the first fixing bracket 301 to ensure that the sensor components after insertion are always towed and moved between the two lateral baffles 213, realizing the limit guiding of the sensor components during the towing process. The first fixing bracket 301 is longitudinally slidably arranged on the horizontal mounting bracket 201. On the lower extension plate 214 fixed at the bottom of the horizontal mounting bracket 201, a reciprocating lead screw 215 is rotatably arranged. The reciprocating lead screw 215 is in transmission cooperation with the towing and conveying frame 203 (the cooperation relationship of the prior art). A towing and conveying gear 216 fixedly arranged at one end of the reciprocating lead screw 215 meshes with the corresponding conversion tooth ring 402. When the reciprocating lead screw 215 is controlled to complete one rotation through the towing and conveying gear 216, a reciprocating motion of the towing and conveying frame 203 is realized. Thus, the sensor components after insertion are conveyed forward by a certain distance, and at this time, the RJ50 crystal head 15 or the RJ50 female socket 13 at the front end of the sensor components just moves between the two terminal clamping parts 211.

[0067] During the process of controlling the rotation positioning mechanism 1 to rotate so that the sensor connection line 9 or the second sensor 8 at the next position moves to the lowermost position, the rotation of the rotation positioning mechanism 1 is divided into two stages. When controlling the rotation positioning mechanism 1 to rotate by half of the angle between two adjacent positioning components 5, during this process, the rotation of the transposition gear ring 402 drives the traction conveying gear 216 to rotate. The reciprocating lead screw 215 that rotates synchronously with the traction conveying gear 216 drives the traction conveying frame 203 to drive the inserted sensor component to move, so that the RJ50 crystal head 15 or the RJ50 female seat 13 at the front end of the sensor component just moves between the two end clamping parts 211 (the first stage); then the clamping and fixing of the signal core wire 11 by the core wire clamping part 205 is released, and the rotation positioning mechanism 1 is continuously controlled to rotate by half of the angle between two adjacent positioning components 5. At this time, the second sensor 8 or the sensor connection line 9 at the next position rotates to the lowermost position, and the rotation of the reciprocating lead screw 215 drives the traction conveying frame 203 back to the initial position (i.e., Figure 11 the position shown), so as to realize the traction and conveying of the sensor component in the production process of the combined sensor, which is beneficial to improving the production efficiency of the sensor combination (the second stage).
