[0049] See also Figures 1 to 8 The present application provides a displacement sensor production line, which can be used to assemble a pipeline assembly 70 of a displacement sensor. The displacement sensor production line (hereinafter referred to as the production line) may include: a first assembly device 100 and a second assembly device 200. The first assembly device 100 can combine a waveguide wire 71, a yellow wax tube 72 and a high-temperature wire 73 to form a tube core structure. The waveguide wire 71 is located in the yellow wax tube 72, and the high-temperature wire 73 is located outside the yellow wax tube 72. The first assembly device 100 can weld one end of the high-temperature wire 73 to one end of the waveguide wire 71 to form a welding end of the tube core structure. The second assembly device 200 is located downstream of the first assembly device 100. The second assembly device 200 may include a mounting plate 230 and a vacuum machine 240. The mounting plate 230 is provided with a first mounting groove 231, the bottom of which is connected to the vacuum machine 240.

The tube core structure and the glass fiber tube 74 are combined to form a pipeline assembly 70.

[0050] When the displacement sensor production line produces displacement sensors, the first assembly device 100 first inserts the waveguide wire 71 into the yellow wax tube 72, so that the waveguide wire 71, the yellow wax tube 72 and the high-temperature wire 73 are combined to form a tube core structure. Afterwards, the first assembly device 100 welds one end of the waveguide wire 71 to one end of the high-temperature wire 73 to form a welding end of the tube core structure.

[0051] The glass fiber tube 74 and the tube core structure are moved to the second assembly device 200 respectively. The outlet end 742 of the glass fiber tube 74 is moved into the first mounting groove 231 of the mounting plate 230, and the welding end of the tube core structure is moved into the line connection end 741 of the glass fiber tube 74. Afterwards, the vacuum machine 240 is started to evacuate the first mounting groove 231, so that the welding end of the tube core structure can extend from the line connection end 741 of the glass fiber tube 74 into the glass fiber tube 74 under the suction of the vacuum machine 240, and then pass through the outlet end 742 of the glass fiber tube 74. The tube core structure is inserted into the glass fiber tube 74, so that the tube core structure and the glass fiber tube 74 are combined to form a pipeline assembly 70. The displacement sensor production line can realize the rapid installation of the tube core structure and the glass fiber tube 74, so as to improve the production efficiency of the displacement sensor and ensure the production accuracy of the displacement sensor.

The guide plate 140 is arranged on the side of the yellow wax tube storage box 120 and the high temperature wire storage box 130 close to the center of the tube die assembly platform 110. After the yellow wax tube storage box 120 outputs the yellow wax tube 72 and the high temperature wire storage box 130 outputs the high temperature wire 73, the guide plate 140 can guide the yellow wax tube 72 and the high temperature wire 73 to move in one direction.

[0070] In other embodiments, the welding fixing platform 171 is connected to the threading support platform 150, and the core welder 173 is movably connected to the welding fixing guide rail 172 so that the core welder 173 can move toward the waveguide wire 71 and the high-temperature wire 73, thereby facilitating welding one end of the waveguide wire 71 and one end of the high-temperature wire 73 to form the welding end of the core structure.

[0071] In some embodiments, a driving structure such as a motor, a cylinder or a gas cylinder may be provided on the die bonder 173 , the welding fixing table 171 or the welding fixing rail 172 to drive the die bonder 173 to move along the welding fixing rail 172 .

The shock-absorbing tube clamping mechanical arm can clamp the shock-absorbing tube in the shock-absorbing tube storage box 174, and can be sleeved on the welding end of the tube core structure to protect the welding end of the tube core structure.

[0073] After the tube core welder 173 welds the waveguide wire 71 and the high temperature wire 73, the tube core welder 173 moves away from the tube core structure. The shock absorbing tube clamping mechanical arm clamps the shock absorbing tube and sets the shock absorbing tube sleeve on the welding end of the tube core structure.

[0074] In this embodiment, the welding and fixing assembly 170 may further include a rivet fixing mechanical arm (not shown in the figure). The rivet fixing mechanical arm is close to the right end of the welding and fixing platform 171. The rivet fixing mechanical arm can move toward the welding end of the tube core structure to limit the tube core structure. The rivet fixing mechanical arm can also output rivets and screw the rivets into the shock absorbing tube to squeeze and fix the welding end of the tube core structure in the shock absorbing tube, thereby ensuring the welding strength of the tube core structure, improving the reliability and stability of the tube core structure, and preventing the connection between the waveguide wire 71 and the high-temperature wire 73 from breaking.

[0075] See also Figure 1 , Figure 2 , Figures 5 to 8 In this embodiment, the production line may further include a second assembly device 200. The second assembly device 200 is located downstream of the first assembly device 100. The second assembly device 200 can receive the tube core structure assembled by the first assembly device 100, and assemble the tube core structure with the glass fiber tube 74 to form the pipeline assembly 70.

[0076] In some embodiments, a first conveyor belt (not shown in the figure) may be provided between the second assembly device 200 and the first assembly device 100.

[0077] In some other embodiments, the first conveyor belt is disposed at the front side of the die assembly platform 110 to facilitate the conveyance of the die structure and the inspection by the staff.

[0078] See also Figure 1 , Figure 2 , Figures 5 to 8 In this embodiment, the second assembly device 200 may include a pipeline assembly platform 210. The pipeline assembly platform 210 is disposed downstream of the tube die assembly platform 110 to carry the tube die structure output by the first assembly device 100.

[0079] In some embodiments, the pipeline assembly platform 210 is located at the right end of the tube core assembly platform 110, so that after the tube core structure is conveyed to the pipeline assembly platform 210 by the first conveyor belt, the pipeline assembly 70 can be processed quickly without changing the orientation of the welding end of the tube core structure, thereby improving the production efficiency of the pipeline assembly 70.

[0080] See also Figure 1 , Figure 2 , Figures 5 to 8In this embodiment, a glass fiber tube storage box 280 may be provided at one end of the pipeline assembly platform 210 away from the tube core assembly platform 110. The glass fiber tube storage box 280 is used to accommodate and store the glass fiber tube 74. In some embodiments, the glass fiber tube storage box 280 is provided at the right end of the pipeline assembly platform 210 to facilitate the use of the glass fiber tube 74 and improve the production efficiency of the pipeline assembly 70.

[0081] See also Figure 1 , Figure 5 and Figure 8 In this embodiment, the second assembly platform may include a mounting plate 230 and a vacuum machine 240. The mounting plate 230 may be provided with a first mounting groove 231, and the bottom of the first mounting groove 231 is connected to the vacuum machine 240. The first mounting groove 231 is used to accommodate the outlet end 742 of the glass fiber tube 74. The line connection end 741 of the glass fiber tube 74 is used for the tube core structure to enter the glass fiber tube 74. When the vacuum machine 240 evacuates the first mounting groove 231, the welding end of the tube core structure can extend into the glass fiber tube 74 from the line connection end 741 of the glass fiber tube 74 under the suction of the vacuum machine 240, and then pass through the outlet end 742 of the glass fiber tube 74. After the tube core structure passes through the glass fiber tube 74, the tube core structure and the glass fiber tube 74 are combined to form the pipeline assembly 70, thereby improving the assembly efficiency of the tube core structure and the glass fiber tube 74 and reducing the production cost of the pipeline assembly 70.

[0082] In some embodiments, the mounting plate 230 may be disposed on the pipeline assembly platform 210 .

[0083] See also Figure 1 , Figure 2 and Figure 5 In this embodiment, the mounting plate 230 can be disposed at the right end of the pipeline assembly platform 210 so that after the fiberglass tube 74 is taken out from the fiberglass tube storage box 280, the outlet end 742 of the fiberglass tube 74 can be quickly moved into the first mounting groove 231 of the mounting plate 230, thereby improving the movement efficiency of the fiberglass tube 74.

The second mounting groove 232 is used to accommodate the outlet end 742 of the glass fiber tube 74. A ejector pin 2321 is protruding from the bottom of the second mounting groove 232. The ejector pin 2321 extends along the extension direction of the second mounting groove 232. When the pipeline assembly 70 extends into the second mounting groove 232, the ejector pin 2321 can be used to push the welding end of the tube core structure into the glass fiber tube 74.

[0086] When the glass fiber tube 74 in the first installation groove 231 is combined with the tube core structure to form the pipeline assembly 70 under the suction of the vacuum machine 240, the pipeline assembly 70 moves from the first installation groove 231 to the second installation groove 232. When the welding end of the tube core structure and the outlet end 742 of the glass fiber tube 74 extend into the second installation groove 232, the rivet and the shock absorbing tube in the tube core structure can contact the ejector pin 2321, so that the rivet and the shock absorbing tube of the tube core structure move into the glass fiber tube 74 under the push of the ejector pin 2321, thereby adjusting the relative position of the glass fiber tube 74 and the tube core structure to protect the tube core structure and facilitate the subsequent processing steps of the pipeline assembly 70 on the production line.

The bending mechanism 270 may be disposed on a side of the end positioning frame 260 away from the mounting plate 230. The bending mechanism 270 is used to accommodate and limit the line connection end 741 of the glass fiber tube 74 moved out from the positioning column 261. The bending mechanism 270 can bend the waveguide wire 71 so that the waveguide wire 71 can be assembled with the circuit board 80 in the subsequent processing steps.

[0096] The bending mechanism 270 may include a bending support frame 271 and a bending pressure block 272. The bending support frame 271 is arranged opposite to the mounting plate 230, and the bending support frame 271 is used to support and limit the line connection end 741 of the glass fiber tube 74. The bending pressure block 272 may be located at one end of the bending support frame 271 away from the mounting plate 230. The bending pressure block 272 is movably arranged on the bending support frame 271, and the bending pressure block 272 can move toward the bending support frame 271 to bend the waveguide wire 71.

[0130] See also Figure 2 , Figures 9 to 11 In this embodiment, the central lead output device 330 can be arranged on the peripheral side of the spot welding accommodating platform 322 so as to be able to output the central lead 75 toward the spot welding accommodating groove 3221, thereby facilitating the central lead 75 to be welded with the waveguide wire 71.

[0131] In some embodiments, the central lead output device 330 can be located below the spot welding accommodation platform 322, so that the central lead 75 can avoid the pressing block 325, which is convenient for the accommodation, limiting and removal of the pipeline assembly 70. The central lead output device 330 is arranged opposite to the lead connecting hole 3223 of the spot welding accommodation platform 322, so that the central lead 75 output by the central lead output device 330 can pass through the lead connecting hole 3223 and extend into the positioning through hole 7411, thereby achieving contact between the central lead 75 and the waveguide wire 71.

[0132] See also Figure 1 , Figures 9 to 11In this embodiment, an output pipe 331 for outputting the central lead 75 may be provided in the central lead output device 330. The axis of the output pipe 331 is perpendicular to the extension direction of the spot welding receiving groove 3221, so that the central lead 75 can be perpendicular to and intersect with the waveguide wire 71.

[0133] The central lead 75 output from the output pipe 331 can be perpendicular to and intersect with the waveguide wire 71 to facilitate the subsequent connection between the pipeline assembly 70 and the circuit board 80, thereby improving the assembly production efficiency of the displacement sensor.

[0134] In some embodiments, the central lead output device 330 can be spaced apart from the spot welding receiving platform 322 to facilitate cutting of the central lead 75 .

[0135] See also Figure 1 , Figure 2 and Fig. 9 In this embodiment, the spot welder 343 is disposed on both sides of the spot welding accommodating platform 322. The spot welder 343 can move toward the spot welding accommodating platform 322, so that the spot welder 343 extends into the spot welding accommodating groove 3221 through the spot welding channel 3224, and then welds the central lead 75 and the waveguide wire 71 through the spot welding groove 7412, thereby realizing fast and accurate welding of the central lead 75 and the waveguide wire 71.

[0136] In some embodiments, the spot welding assembly platform 310 may be provided with a first spot welding guide rail 341 and a second spot welding guide rail 342.

The second spot welding guide rail 342 can extend along the extension direction of the spot welding channel 3224, and the spot welder 343 is movably arranged on the second spot welding guide rail 342 so that the spot welder 343 can move on the second spot welding guide rail 342 and extend into the spot welding channel 3224.

[0137] When the second assembly device 200 is inspected and maintained, the second spot welding guide rail 342 moves on the first spot welding guide rail 341 in a direction away from the spot welding accommodating platform 322 to move the spot welder 343 away from the spot welding accommodating platform 322, thereby facilitating the inspection and maintenance of the spot welder 343 by the staff.

[0138] When the second assembly device 200 welds the central lead 75 and the waveguide wire 71, the second spot welding guide rail 342 moves on the first spot welding guide rail 341 to position the spot welder 343 relative to the spot welding channel 3224. The spot welder 343 is then moved on the second spot welding guide rail 342 toward the spot welding accommodating platform 322 so that the spot welder 343 can extend into the spot welding channel 3224 and spot weld the central lead 75 and the waveguide wire 71 through the spot welding groove 7412.

[0139] In some embodiments, the second spot welding guide rail 342 moves on the first spot welding guide rail 341 to adjust the position of the spot welder 343, so that the spot welder 343 can accurately align the connection between the waveguide wire 71 and the central lead 75 to improve the accuracy and efficiency of spot welding, thereby improving the production efficiency and production quality of the pipeline assembly 70.

[0140] In some embodiments, a driving structure is provided between the first spot welding rail 341, the second spot welding rail 342 and the spot welder 343 to drive the second spot welding rail 342 and the spot welder 343 to move.

[0142] See also Figure 1 , Figure 2 and Fig. 9 In this embodiment, the third assembly device 300 may further include a cutting rail 351 and a cutter 352. The cutting rail 351 is disposed on the peripheral side of the pipeline carrier 320. The cutting rail 351 extends toward the spot welding accommodating platform 322. The cutter 352 is movably disposed on the cutting rail 351. The cutter 352 can move toward between the spot welding accommodating platform 322 and the central lead output device 330 to cut the central lead 75.

[0143] In some embodiments, the cutting rail 351 is disposed near the left end of the spot welding accommodating platform 322. The cutting rail 351 extends in the left-right direction, and the cutter 352 is disposed on the cutting rail 351 so as to be movable left-right, so that the cutter 352 approaches and cuts the central lead 75.

[0144] The cutter 352 moves toward the spot welding accommodating table 322 so as to be able to extend between the lower surface of the spot welding accommodating table 322 and the upper part of the central lead output device 330, thereby being able to cut off the central lead 75, so as to be able to accurately transport the fixed-length central lead 75 and improve the cutting efficiency of the central lead 75.

[0145] Moreover, in the up and down direction, the cutter 352 is located at the lower side of the spot welding accommodating platform 322. When the pipeline assembly 70 is accommodated in the electric welding accommodating groove, the bent portion of the waveguide wire 71 extends upward from the spot welding accommodating platform 322 to prevent the waveguide wire 71 from contacting the cutter 352, thereby ensuring the stability of the cutter 352 during movement, and preventing the waveguide wire 71 from contacting the cutter 352, thereby ensuring the safety of the waveguide wire 71.

[0146] In some embodiments, the drive structure on the cutter 352 and the cutting guide rail 351 can refer to the above-mentioned drive structure, which can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0178] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0179] See also Figures 1 to 15 In the present invention, when the displacement sensor is produced on the production line, the yellow wax tube storage box 120 outputs the yellow wax tube 72, and the high temperature wire storage box 130 outputs the high temperature wire 73. The yellow wax tube 72 and the high temperature wire 73 are moved into the threading accommodating groove 152 under the action of the guide plate 140. The threader 160 outputs the waveguide wire 71 so that the waveguide wire 71 is inserted into the yellow wax tube 72. After the waveguide wire 71 output by the threader 160 passes through the yellow wax tube 72, the threading cutting piece 162 cuts the waveguide wire 71, and the welding fixing assembly 170 welds one end of the waveguide wire 71 and one end of the high temperature wire 73.

[0180] After the waveguide wire 71 and the high temperature wire 73 are welded, the damping tube clamping mechanical arm clamps the damping tube and sleeves it on the welding end of the tube core structure. The rivet fixing mechanical arm screws the rivet into the damping tube to ensure the structural strength of the welding end of the tube core structure and prevent the welding end of the tube core structure from breaking.

[0181] After the tube core structure is processed, the tube core structure is moved to the second assembly device 200. The glass fiber tube 74 is moved onto the mounting plate 230 so that the outlet end 742 of the glass fiber tube 74 extends into the first mounting groove 231 of the mounting plate 230. The tube core structure extends into the line connection end 741 of the glass fiber tube 74. When the vacuum machine 240 evacuates the first mounting groove 231, the welding end of the tube core structure can extend from the line connection end 741 of the glass fiber tube 74 into the glass fiber tube 74 under the suction of the vacuum machine 240, and then pass through the outlet end 742 of the glass fiber tube 74, so that the tube core structure and the glass fiber tube 74 are combined to form the pipeline assembly 70.

[0182] After the pipeline assembly 70 is assembled in the first installation groove 231, the pipeline assembly 70 is moved from the first installation groove 231 to the second installation groove 232. The ejector pin 2321 in the second installation groove 232 pushes the welding end of the tube core structure into the glass fiber tube 74 so that the glass fiber tube 74 protects the tube core structure.

[0183] After the pipeline assembly 70 is processed in the second installation groove 232, the pipeline assembly 70 is moved out of the second installation groove 232, and the line connection end 741 of the fiberglass tube 74 is moved into the bending mechanism 270. The bending mechanism 270 bends the waveguide wire 71 at the line connection end 741 to facilitate the connection between the waveguide wire 71 and the circuit board 80 in the subsequent process.

[0184] After the pipeline assembly 70 is processed in the bending mechanism 270, the pipeline assembly 70 moves from the second assembly device 200 to the third assembly device 300. The line connection end 741 of the glass fiber tube 74 moves into the spot welding accommodating groove 3221 on the spot welding accommodating platform 322, and the waveguide wire 71 moves into the avoidance groove 3222, and then the pressing block 325 is pressed on the spot welding accommodating platform 322 to limit the pipeline assembly 70 on the spot welding accommodating platform 322.

[0185] After the pipeline assembly 70 is limited on the pipeline carrier 320, the central lead output device 330 outputs the central lead 75. The central lead 75 passes through the lead connecting hole 3223 and the positioning through hole 7411 to contact the waveguide wire 71. After the central lead 75 contacts the waveguide wire 71, the spot welder 343 moves relative to the first movable guide rail 441 and the second movable guide rail 442, so that the spot welding needle of the spot welder 343 can extend through the spot welding channel 3224 and the spot welding groove 7412 to the connection between the central lead 75 and the waveguide wire 71, thereby spot welding the central lead 75 and the waveguide wire 71.

[0186] After the spot welder 343 welds the central lead 75 to the waveguide wire 71 , the cutter 352 moves on the cutting guide rail 351 toward the spot welding accommodating platform 322 to cut the central lead 75 .

[0187] After the cutter 352 cuts off the central lead 75, the pressing block 325 moves away from the spot welding accommodating platform 322, and the pipeline assembly 70 moves from the spot welding accommodating platform 322 to the second conveyor belt 610. The second conveyor belt 610 conveys the pipeline assembly 70 to the fourth assembly device 400. The pipeline assembly 70 moves and is confined in the line accommodating platform 420.

[0188] After the line connection end 741 of the glass fiber tube 74 is accommodated in the line accommodation platform 420, the circuit board 80 is moved onto the line accommodation platform 420, and the circuit board 80 is attached to the pipeline assembly 70. Afterwards, the first limiting structure 430 presses the circuit board 80 on the pipeline assembly 70, and the automatic screw assembly 440 screws the line connection end 741 of the glass fiber tube 74 and the circuit board 80 to form a displacement sensor.

[0189] When the pipeline assembly 70 is connected to the circuit board 80 to form the displacement sensor, the automatic screw assembly 440 and the first stopper structure are away from the circuit accommodating platform 420. The displacement sensor moves from the circuit accommodating platform 420 to the assembly welding platform 450 to electrically connect the waveguide wire 71, the high-temperature wire 73 and the circuit board 80.

[0190] After the waveguide wire 71, the high temperature wire 73 and the circuit board 80 are welded, the displacement sensor self-assembly welding station 450 is moved to the second conveyor belt 610. The second conveyor belt 610 conveys the displacement sensor to the quality inspection device 500.

[0191] After the displacement sensor is delivered to the quality inspection device 500, the displacement sensor moves into the quality inspection accommodating groove 521 of the quality inspection accommodating platform 520. The second limit assembly limits the displacement sensor on the quality inspection accommodating platform 520, and the quality inspection assembly 540 performs circuit testing on the displacement sensor to ensure the production quality of the displacement sensor.

[0192] When the quality inspection of the displacement sensor is completed, the displacement sensor moves from the quality inspection accommodating table 520 to the second conveyor belt 610, and the second conveyor belt 610 conveys the displacement sensor to the product placement rack 620 for temporary storage of the displacement sensor.

[0194] See also Figure 1 , Figure 2 , Figure 5 and Fig.16 The present invention also provides a displacement sensor production method, which is applied to the displacement sensor production line as above. The production line may include a first assembly device 100 and a second assembly device 200.

[0195] Step S100, after the first assembling device 100 inserts the waveguide wire 71 into the yellow wax tube 72, one end of the waveguide wire 71 is welded to one end of the high-temperature wire 73, so that the waveguide wire 71, the yellow wax tube 72 and the high-temperature wire 73 are assembled to form a tube core structure.

[0196] In step S200, the outlet end 742 of the glass fiber tube 74 moves and is limited in the first mounting groove 231 of the mounting plate 230. When the vacuum machine 240 is started, the vacuum machine 240 evacuates the space in the first mounting groove 231 and the space in the glass fiber tube 74, so that the welding end of the tube core structure is sucked into the glass fiber tube 74 from the line connection end 741 of the glass fiber tube 74, and then passes through the glass fiber tube 74 from the outlet end 742 of the glass fiber tube 74, so that the glass fiber tube 74 and the tube core structure are combined to form a pipeline assembly 70.

[0197] When the displacement sensor is being produced, the welding end of the tube core structure moves in the glass fiber tube 74 under the action of the vacuum machine 240, and then passes through the glass fiber tube 74 from the outlet end 742 of the glass fiber tube 74, thereby realizing the rapid installation of the tube core structure and the glass fiber tube 74, so as to improve the production efficiency of the displacement sensor.

[0216] Step S320 , when the spot welder 343 extends toward the intersection of the waveguide wire 71 and the central lead wire 75 , the spot welder 343 welds the central lead wire 75 to the waveguide wire 71 .
