Description

Technical Field

[0001] The invention relates to the technical field of thermocouple production, and in particular to automated thermocouple production integrated equipment. Background Art

[0002] In the traditional thermocouple production process, the welding process of platinum wire and rhodium wire often needs to rely on manual operation. The operator needs to cut the two metal wires to the preset length, and then manually adjust their relative positions to align their ends and place them at the welding station. Finally, the connection is completed by welding equipment. Figure 11 The U-shaped quartz tube 1 of the prior art is shown. However, this manual production method has many disadvantages: on the one hand, the accuracy of manual cutting of the metal wire is difficult to guarantee, and the length error can easily lead to fluctuations in the measurement accuracy of the thermocouple. On the other hand, during the manual alignment process, the relative position stability of the platinum wire and the rhodium wire is poor, and problems such as offset and tilt are prone to occur, which directly affects the consistency and firmness of the welding point, thereby reducing the product qualification rate.

DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] First embodiment: like Figure 1 、 Figure 2As shown, this embodiment provides an automated thermocouple production integrated device, including a base 2 and a welding station 10. The welding station 10 is set on the base 2. The welding station 10 includes a welding mechanism 11 and two wire feeding mechanisms 12, and the two wire feeding mechanisms 12 are symmetrically arranged on both sides of the welding mechanism 11. The welding mechanism 11 includes a chassis 110 and two lifting rods 111, one end of the two lifting rods 111 can be lifted and lowered on the chassis 110, and the other ends of the two lifting rods 111 are fixed with welding columns 112, each lifting rod can be connected to the lifting mechanism of the prior art, and the lifting mechanism can be a cylinder. The lifting mechanism of this new model adopts the prior art, so it will not be described in detail. The opposite surfaces of the two welding columns 112 can be relatively abutted through the lifting rods 111. The two welding columns 112 are connected to the welding equipment of the prior art, and the two welding columns 112 are working to weld platinum wire or rhodium wire. Each wire feeding mechanism 12 includes a housing 120, a first track 121, a first cylinder 124 and an automatic shear 122. The housing 120, the chassis 110, the automatic shear 122 and the first track 121 are all fixed on the base 2. The automatic shear 122 of the present invention adopts the existing technology, so it will not be described in detail. The top of the automatic shear 122 has an automatic shear that can cut platinum wire or rhodium wire. The first slider 123 is slidably arranged in the first track 121. The cylinder seat of the first cylinder 124 is fixedly connected to the first track 121, and the piston rod is fixedly connected to the first slider 123. A removable wire wheel 125 is arranged in the housing 120. Figure 2 As shown, a conduit 126 is provided on one side of the housing 120. Two wire wheels 125 are respectively wound with platinum wire and rhodium wire, one end of the platinum wire or rhodium wire passes through the conduit 126 and the automatic shear 122, which is located between the conduit 126 and the welding column 112.

[0019] The operator first installs the wire reels 125 wound with platinum wire and rhodium wire in the casings 120 of the two wire feeding mechanisms 12 respectively, and passes one end of the platinum wire and the rhodium wire through the guide tube 126 on the corresponding casing 120, and then extends them to the welding column 112 through the automatic shear 122. The first cylinder 124 is started, and its piston rod pushes the first slider 123 to slide along the first track 121, driving the wire feeding mechanism 12 to adjust its position so that the ends of the platinum wire and the rhodium wire are precisely aligned with the welding area between the welding columns 112. The two lifting rods 111 of the welding mechanism 11 descend or rise synchronously, driving the two welding columns 112 to approach and abut against each other, and welding the ends of the platinum wire and the rhodium wire. After welding is completed, the lifting rod 111 rises, the welding column 112 separates, and the two first cylinders 124 are driven to work. The two first cylinders 124 drive the housing 120 to move synchronously back and forth through the first slider 123 until the platinum wire and rhodium wire are pulled to a specific length. The automatic shear 122 is activated to cut the platinum wire and rhodium wire to the preset length. The first cylinder 124 drives the first slider 123 to return to the original position, and the wire feeding mechanism 12 refeeds the wire to prepare for the next welding. This cycle realizes the automated operation of platinum wire and rhodium wire welding in thermocouple production. This structural arrangement further improves work efficiency.

[0020] Second embodiment: like Figures 1-8 As shown, the automated thermocouple production integrated equipment further includes a transfer station 20 and a threading station 30. The transfer station 20 is located downstream of the welding station 10, and the threading station 30 is located downstream of the transfer station 20. Both the transfer station 20 and the threading station 30 are arranged on the base 2. The transfer station 20 includes a robotic arm 21, as shown in FIG. Figure 2 As shown, a gripper 22 for clamping the platinum-rhodium wire 3 is provided on the robotic arm 21. The gripper 22 adopts the existing technology, so it will not be described in detail. Figure 1As shown, the robotic arm 21 includes a second rail 23, a third rail 24, and a bracket 25. A second slider 26 is slidably mounted in the second rail 23, the second slider 26 is fixedly coupled to the third rail 24, and the second slider 26 is connected to a second driving member 27 for driving the second slider 26 to slide along the second rail 23. The second driving member 27 is a second cylinder, the cylinder seat of the second cylinder is fixedly coupled to the second rail 23, and the second cylinder piston rod is fixedly coupled to the second slider 26. A third slider 28 is slidably mounted in the third rail 24, the third slider 28 is fixedly coupled to the bracket 25, and the third slider 28 is connected to a third driving member 29 for driving the third slider 29 to slide along the third rail 24. The third driving member 29 is a third cylinder, the cylinder seat of the third cylinder is fixedly coupled to the third rail 24, and the third cylinder piston rod is fixedly coupled to the third slider 28. The second rail 23 and the third rail 24 are vertically offset, and the gripper 22 is fixedly coupled to the bracket 25. The threading station 30 includes a stand 31 and a transverse moving mechanism 32. The stand 31 is fixed on the base 2. The transverse moving mechanism 32 is arranged on the stand 31. The transverse moving mechanism 32 is connected to a manipulator 33 for clamping the U-shaped quartz tube 1. The manipulator 33 of the present invention adopts the existing technology, so it will not be described in detail. Figure 1 、 Figure 3 、 Figure 8 As shown, the transverse movement mechanism 32 includes a fourth track 320, a truss 321, and a second motor 322. A fourth slider 323 is slidably mounted within the fourth track 320, which is fixed to the platform 31. A strip-shaped slot 324 is defined along one side of the fourth track. The truss 321 is fixedly connected to the manipulator 33 at each end of the fourth slider 323. Two lugs 325 are fixed to one side of the fourth track 320. Guide rods 326 and a lead screw 327 are provided on the two lugs 325 along the length of the fourth track 320. The lead screw 327 is pivotally mounted on the two lugs 325. The base of the second motor 322 is fixedly mounted to one of the lugs 325, and the output shaft of the second motor 322 is coaxially connected to the lead screw 327. The guide rod 326 and the lead screw 327 are movably sleeved with a driving block 328, which is threadedly sleeved on the lead screw 327. The driving block 328 is fixed with a connecting rod 329, and the end of the connecting rod 329 away from the driving block 328 passes through the strip groove 324 and is fixed to the fourth slider 323. Figure 1 、 Figure 7As shown, rollers 34 are rotated side by side on one side of the stand 31, and the annular walls of the two flexible rollers 34 are arranged in contact with each other. Any roller 34 is connected to the first motor 35, and the base of the first motor 35 is fixed to the stand 31. The platinum-rhodium wire 3 can be held between the two rollers 34 by the gripper 22. Among them, the open end of the vertically arranged U-shaped quartz tube 1 faces the two rollers 34. The rollers 34 rotate to transfer the platinum-rhodium wire 3 into the U-shaped quartz tube 1. The conveying station 20 also includes a fourth cylinder 200. The cylinder base of the fourth cylinder 200 is fixed to the bracket 25, and the piston rod is coaxially connected to the mounting rod 201. The mounting rod 201 has a receiving groove 202 along its length direction at one end away from the fourth cylinder 200. One end of the platinum-rhodium wire 3 is mounted in the receiving groove 202, and the other end is clamped on the gripper 22.

[0021] The workflow of the above scheme is as follows: after adding the conveying station 20 and the threading station 30, the workflow of the equipment is further extended on the basis of the original welding station. After the welding station 10 completes the welding of the platinum wire and the rhodium wire to form the platinum-rhodium wire 3, the conveying station 20 starts working. The second cylinder is started, and the piston rod pushes the second slider 26 to slide along the second track 23. At the same time, the third cylinder drives the third slider 28 to slide along the third track 24, driving the gripper 22 on the bracket 25 to move precisely to the welding column 112. The gripper 22 clamps the welded platinum-rhodium wire 3. The conveying station 20 includes a fourth cylinder 200. At this time, the piston rod of the fourth cylinder 200 extends, causing the erection rod 201 to move to the appropriate position. One end of the platinum-rhodium wire 3 is erected in the receiving groove 202 of the erection rod 201, and the other end is still clamped by the gripper 22 to keep the platinum-rhodium wire 3 stable during the conveying process. Subsequently, the second and third cylinders work together again, sliding the second and third sliders 26 and 28 to convey the platinum-rhodium wire 3 between the two rollers 34 of the threading station 30. The gripper 22 releases the platinum-rhodium wire 3, clamping it between the rollers 34. When the threading station 30 is activated, the first motor 35 rotates the rollers 34 connected to it, and the two rollers 34 cooperate to convey the platinum-rhodium wire 3 forward. Simultaneously, the lateral movement mechanism 32 begins to operate: the second motor 322 drives the lead screw 327 to rotate. Because the drive block 328 is threaded onto the lead screw 327 and slidably engages with the guide rod 326, the rotation of the lead screw 327 drives the drive block 328 along the guide rod 326. This, in turn, drives the fourth slider 323 along the fourth track 320 via the connecting rod 329. This, in turn, causes the gantry 321 to drive the manipulator 33 to move laterally, adjusting the position of the U-shaped quartz tube so that the open end of the vertically arranged U-shaped quartz tube is precisely aligned with the conveying path of the platinum-rhodium wire 3. Under the continuous rotation of roller 34, the platinum-rhodium wire 3 is smoothly transferred into the U-shaped quartz tube, completing the threading operation. All components are reset, preparing for the next cycle of the entire process, from welding to threading. Throughout this process, the transfer station 20 automates the transfer of the platinum-rhodium wire 3 from the welding station 10 to the threading station 30. The threading station 30, through the cooperation of the transverse movement mechanism 32 and roller 34, precisely threads the platinum-rhodium wire 3 into the U-shaped quartz tube, further improving the automation and efficiency of thermocouple production.

[0022] Third embodiment: like Figure 1 、 Figure 4As shown, the automated thermocouple production integrated equipment also includes a guide station 40, which includes a fifth track 41, a fifth cylinder 42, and a tilting rod 43. The fifth track 41, fixed on the base 2, is offset and perpendicularly arranged with the fourth track 320, and a fifth slider 44 is slidably arranged on the fifth track 41. The fifth slider 44 is fixed to the tilting rod 43 via a vertical plate 45. The fifth cylinder 42 is fixed to the cylinder base and the fifth track 41, and the piston rod is fixed to the vertical plate 45 via a horizontal plate 46. The table top of the stand 31 has a notch 310. The tilting rod 43 can pass through the notch 310 through the fifth cylinder 42 and be inserted into the open end of the U-shaped quartz tube 1 located on the robot 33.

[0023] With the addition of the guide station 40, the equipment's workflow further extends the existing basic threading station 30. After the transfer station 20 transfers the platinum-rhodium wire 3 to the two rollers 34 of the threading station 30 and completes the clamping, the guide station 40 is activated. The fifth cylinder 42 extends the piston rod, which pushes the vertical plate 45 via the horizontal plate 46, causing the fifth slider 44 to slide along the fifth track 41, driving the tilting rod 43 through the notch 310 in the tabletop of the platform 31 until the end of the tilting rod 43 is positioned corresponding to the open end of the U-shaped quartz tube 1 held by the manipulator 33. At this point, the open end of the U-shaped quartz tube 1 held by the manipulator 33 faces the rollers, completing the threading process. The manipulator 33 releases its grip on the U-shaped quartz tube 1. Due to the loss of gripping force, the open end of the U-shaped quartz tube 1 shifts from facing the rollers to facing downward, resting squarely on the tilting rod 43. At this point, gravity forces the U-shaped quartz tube 1 downward along the tilted direction of the tilt rod 43, smoothly transitioning to the next workstation. Simultaneously, the piston rod of the fifth cylinder 42 retracts, driving the tilt rod 43, via the fifth slider 44, back along the fifth track 41, clearing the notch 310 of the gantry 31 and preparing for the next guiding operation. During this process, the tilt rod 43 not only provides precise guidance for the platinum-rhodium wire 3 to penetrate the U-shaped quartz tube, but also receives the U-shaped quartz tube 1 after the robot arm 33 is released, enabling its automatic transfer to the subsequent workstation by gravity. This further enhances the automation consistency of the equipment, reduces manual intervention, and improves production efficiency.

[0024] like Figures 1-10 As shown, the automated thermocouple production integrated equipment further includes a pipe supply station 50, which includes a vibration plate 51, a conveying track 52, a bending rod 53 and a guide rod 54. Figure 5 As shown, the conveying track 52 has a horizontal section 520 and an inclined section 521. The horizontal section 520 is fixed on the platform 31 and is located directly below the robot 33. Figure 9As shown, a notch 5211 is provided on one side of the feed end of the inclined section 521, a slope 522 is provided outside the notch 5211, and the guide rod 54 is fixedly connected to one side of the slope 522 through a support plate 523. Figure 10 As shown, an arc-shaped gentle slope 511 is fixed in the vibration disk 51. The vibration disk 51 of the present invention adopts the existing technology, so it will not be described in detail. The transmission tail end of the arc-shaped gentle slope 511 is fixed to one end of the bending rod 53, and the other end is inserted in the notch; a certain distance is reserved between the bending rod and the inner wall of the inclined section, and the distance is for the U-shaped quartz tube to pass through. The height of one end of the bending rod 53 inserted into the notch 5211 is lower than the height of the end thereof fixed to the arc-shaped gentle slope 511, and the height gradually decreases near the transmission track 52. A first arc plate 512 and a second arc plate 513 are fixed on the arc-shaped gentle slope 511. The first arc plate 512, the second arc plate 513 and the top wall of the arc-shaped gentle slope 511 form a transmission channel 514. The transmission channel 514 gradually narrows near the bending rod 53. The feed end of the bending rod 53 is located directly below the transmission tail end of the transmission channel 514. The guide rod 54 is located below the curved rod 53 , and the guide rod 54 and the curved rod 53 are close to the slope 522 , so that the two gradually approach each other.

[0025] The vibrating plate 51 begins operating, and the U-shaped quartz tubes 1 within it lie flat on the curved gentle slope 511. Under the action of vibration, they move along the curved gentle slope 511 toward the conveyor tail end. Because the first curved plate 512 and the second curved plate 513 are positioned on the curved gentle slope 511, they, together with the top wall of the curved gentle slope 511, form a gradually narrowing conveying channel 514. Within this conveying channel 514, the U-shaped quartz tubes 1 are organized and conveyed in an orderly manner toward the curved rod 53. When the U-shaped quartz tubes 1 reach the conveyor tail end of the curved gentle slope 511, they fall onto the feed end of the curved rod 53 (some U-shaped quartz tubes fall directly onto the vibrating plate 51). At this point, the U-shaped quartz tubes 1 resting on the curved rod 53 are positioned open and facing downward. As the curved rod 53 gradually decreases in height as it approaches the conveyor track 52, gravity forces the U-shaped quartz tubes 1 to slide along the curved rod 53 toward the notch 5211. When the U-shaped quartz tube 1 is transferred to the vicinity of the guide rod 54, it rotates due to the combined action of the guide rod 54, which is positioned below and to the side of the curved rod 53, and the two gradually converge toward the slope 522. As the curved rod 53 and guide rod 54 continue to converge, the U-shaped quartz tube 1 gradually rotates 90 degrees, eventually sliding up the slope 522 in a suitable position and being transferred to the inclined section 521 of the transfer track 52. Once in the inclined section 521, the U-shaped quartz tube 1 continues to slide due to gravity, eventually entering the horizontal section 520 (located directly below the robot 33), completing the transfer process from the tube feeding station 50 and preparing the robot 33 to grasp the U-shaped quartz tube and transfer it to the threading station 30. The entire process ensures seamless connection between subsequent workstations and improves the overall automation level of the equipment.

[0026] like Figure 3 、 Figure 5 As shown, the automated thermocouple production integrated equipment also includes an extension plate 55, a support plate 56, and a mounting post 57. One end of the extension plate 55, axially arranged along the lead screw 327, is fixedly connected to the truss 321. The other end of the extension plate 55, facing one side of the fifth track 41, defines a convex groove 550. An insert plate 551 is slidably disposed within the convex groove 550. A shaft 552 is fixed to the top wall of the insert plate 551 and extends through the convex groove 550. A spring 553 is fixed to the inner end of the insert plate 551, away from the inner wall of the convex groove 550 of the insert plate 551. The outer end of the insert plate 551 can be inserted between two adjacent U-shaped quartz tubes 1. The inclined support plate 56 is fixedly connected to the fourth track 320 via a bent rod 59. The shaft 552 can abut against both side walls of the support plate 56. The mounting column 57 is fixed on the horizontal section 520 , and a flexible baffle 571 is fixed on the top end. The flexible baffle 571 can abut against the U-shaped quartz tube 1 located in the horizontal section 520 .

[0027] With the addition of the extension plate 55, abutment plate 56, and mounting post 57, the equipment operates as follows during the process of transferring the U-shaped quartz tube 1 from the tube supply station 50 to the threading station 30: as the U-shaped quartz tube from the tube supply station 50 passes through the horizontal section 520, the flexible baffle 571 at the top of the mounting post 57 abuts against the U-shaped quartz tube 1 within the horizontal section 520, blocking it and preventing it from sliding excessively due to inertia. This ensures that the U-shaped quartz tube 1 at the front end of the horizontal section 520 remains within the gripping range of the manipulator 33. When the lateral movement mechanism 32 of the threading station 30 operates, the gantry 321 drives the extension plate 55 in synchronous movement. Initially, the outer end of the insert plate 551 extends beyond the extension plate 55 under the elastic force of the spring 553. As the gantry 321 moves toward the horizontal section 520, the shaft 552 gradually approaches the inner wall of the abutment plate 56. When the shaft 552 abuts the inner sidewall of the abutment plate 56, the abutment plate 56 pushes the shaft 552, causing the insert plate 551 to retract into the convex groove 550. The shaft 552 separates from the abutment plate. The spring allows for insertion and removal, allowing the shaft 552 to be inserted between the two U-shaped quartz tubes located behind the flexible baffle 571. After the manipulator 33 grasps the U-shaped quartz tube 1 at the front end of the horizontal section 520, the truss 321 drives the extension plate 55 in the opposite direction. The shaft 552 abuts the outer sidewall of the abutment plate 56, and the insert plate 551 extends outward under the elastic force of the spring 553. The insert plate also drives the U-shaped quartz tube at the front end along the horizontal section until it reaches the ready-to-grab position. Simultaneously, the mounting post 57 and the flexible baffle 571 on the horizontal section 520 continue to function, blocking subsequent U-shaped quartz tubes 1, keeping them orderly arranged within the horizontal section 520, awaiting the next grasping by the manipulator 33. When the robot 33 moves the U-shaped quartz tube 1, the flexible baffle 571 can be pushed aside due to its flexibility, without affecting the transmission of the U-shaped quartz tube 1. After the tube passes, it returns to its original shape and continues to block the subsequent U-shaped quartz tube 1. Throughout this process, the extension plate 55 and the insert plate 551 cooperate to separate the U-shaped quartz tubes 1 one by one. The abutment plate 56 controls the extension and retraction of the insert plate 551 by abutting against the shaft 552. The mounting post 57 and the flexible baffle 571 ensure that the U-shaped quartz tube 1 stays in an orderly manner in the horizontal section 520, further improving the accuracy and stability of the tube feeding device.
