Description

Technical Field

[0001] The invention relates to the technical field of thermocouple compensation wire welding, and more specifically, to a welding device for processing thermocouple compensation wire and a welding method thereof. Background Art

[0002] A thermocouple is a commonly used temperature measurement device. It consists of two conductors of different metals or alloys welded together to form a closed loop. Thermocouples are based on the thermoelectric potential difference generated by two different metals when the temperature changes. This thermoelectric potential difference is related to the type of the two metals and the temperature difference between the two ends. One end of the thermocouple (usually called the hot junction) is exposed to the measured temperature, while the other end (cold junction) is kept at a known temperature. By measuring the voltage between the two ends, the temperature of the hot junction can be determined. The compensation wire is a special wire used to extend the cold end of the thermocouple to a place away from high temperature and with a more stable temperature. It is usually welded to the connecting end of the thermocouple.

[0003] Thermocouples are usually divided into S-type thermocouples, K-type thermocouples, E-type thermocouples, J-type thermocouples and T-type thermocouples. When welding thermocouples and compensation wires, the corresponding compensation wires can only be used with thermocouples of the corresponding models, and they cannot be used if the models are inconsistent.

[0004] However, the existing thermocouple compensation wire welding device can only perform welding by manually placing thermocouples and compensation wires of the same type, and cannot automatically match thermocouples of suitable types for welding according to the type of compensation wire. Manually selecting thermocouples and compensation wires of different types for welding can easily lead to incorrect selection of thermocouples and compensation wires, indirectly causing the welded thermocouple compensation wires to be scrapped, resulting in production waste.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0055] For example, see Figure 1-10 The present invention provides the following technical solutions: A welding device for processing thermocouple compensation wires, comprising a work table 7, a welding mechanism 1 is provided on the upper side of the work table 7, a control box 8 is provided on the upper side of the welding mechanism 1, a camera 2 is provided on one side of the welding mechanism 1, an adjustment mechanism 4 is also provided on one side of the welding mechanism 1, a first manipulator 5 is provided on one side of the adjustment mechanism 4 and a transmission mechanism 3 is provided on the other side, and a second manipulator 6 is provided on one side of the transmission mechanism 3.

[0056] Specifically, the first manipulator 5 is used to place thermocouples of different types into the interior of the adjustment mechanism 4, the second manipulator 6 is used to place compensation wires of different types into the interior of the transmission mechanism 3, the welding mechanism 1 is used to weld thermocouples and compensation wires, the camera 2 is used to capture images of the inner core and insulation layer of compensation wires of different types, the adjustment mechanism 4 is used to transmit thermocouples of different types for welding, and the transmission mechanism 3 is used to transmit compensation wires of different types for welding.

[0057] See also Figure 2 The first manipulator 5 includes a base 53 , which is fixedly connected to one side of the work table 7 , a manipulator 52 is fixedly connected to one side of the base 53 , and a first clamp 51 is fixedly connected to the other end of the manipulator 52 .

[0058] Specifically, the mechanical arm 52 is used to control the first clamping jaw 51 to reach different areas, and the first clamping jaw 51 is used to clamp or place the thermocouple compensation wire.

[0059] The control box 8 is provided with a control module, a detection module and a database, and the database is provided with identification photos of different colors and different numbers of inner cores of the internal insulation layer of the compensation wire.

[0060] See also Figure 3 The transmission mechanism 3 includes a second support plate 36, which is fixedly connected to the upper side of the work table 7. The upper side of the second support plate 36 is fixedly connected to the second cylinder 35, and the output end of the second cylinder 35 is fixedly connected to the second slide seat 34. A second slide rail 33 is provided on one side of the second support plate 36. The lower side of the second slide rail 33 is fixedly connected to the welding mechanism 1 and the upper side is slidably connected to the second slide seat 34. The upper side of the second slide seat 34 is fixedly connected to the top plate 32, and the two ends of the top plate 32 are respectively fixedly connected to the second clamping jaws 31.

[0061] Specifically, the clamping end of the second clamping jaw 31 is used to place compensation wires of different types, and the extension and retraction of the output end of the second cylinder 35 is used to control the movement of the compensation wire, so as to make the compensation wire approach or move away from the welding mechanism 1.

[0062] When welding is required, the robot arm 52 controls the first clamp 51 to reach the area where the compensation wires are accumulated. The first clamp 51 clamps one of the compensation wires and clamps it to the clamping end of the second clamp 31. The output end of the second cylinder 35 extends to control the compensation wire to reach the position of the welding mechanism 1. The adjustment mechanism 4 then transmits the thermocouple to the position of the welding mechanism 1, and the welding mechanism 1 automatically welds the thermocouple and the compensation wire.

[0063] By providing the welding mechanism 1, the adjusting mechanism 4 and the transmission mechanism 3, thermocouples and compensation wires of different types can be transmitted to a designated area for automatic welding, thereby achieving the effects of automatic welding of thermocouple compensation wires and high welding efficiency.

[0064] Embodiment 2: The existing thermocouple compensation wire welding device can only perform welding by manually placing thermocouples and compensation wires of the same type. It is impossible to automatically match thermocouples of the appropriate type for welding according to the type of compensation wire. Manually selecting thermocouples and compensation wires of different types for welding can easily lead to incorrect selection of thermocouples and compensation wires, indirectly causing the welded thermocouple compensation wires to be scrapped, resulting in production waste. Therefore, the following structure is designed to solve the above technical problems.

[0065] See also Figure 4 The adjustment mechanism 4 includes a first support plate 49, which is fixedly connected to the upper side of the work table 7. The upper side of the first support plate 49 is fixedly connected to the first cylinder 45, and the output end of the first cylinder 45 is fixedly connected to the first slide seat 48. A first slide rail 46 is provided on one side of the first support plate 49, and the lower side of the first slide rail 46 is fixedly connected to the welding mechanism 1 and the upper side is slidably connected to the first slide rail 46.

[0066] Specifically, the extension and retraction of the output end of the first cylinder 45 is used to control the movement of the first slide 48, thereby controlling the turntable 47 on the first slide 48 to approach or move away from the welding mechanism 1, thereby moving the thermocouple to a designated area for welding.

[0067] The upper side of the first slide 48 is fixedly connected to a transmission box 41, the interior of the transmission box 41 is fixedly connected to a first motor 44, the output end belt of the first motor 44 is connected to a rotating wheel 43, the two ends of the rotating wheel 43 are respectively fixedly connected to a first rotating shaft and a second rotating shaft, the first rotating shaft is connected to a bearing of the transmission box 41, and the second rotating shaft is fixedly connected to a turntable 47.

[0068] Specifically, the rotation of the output end of the first motor 44 is used to control the rotation of the rotating wheel 43 . When the rotating wheel 43 rotates, it drives the rotating disk 47 to rotate, thereby controlling the thermocouple on the rotating disk 47 to rotate.

[0069] The first hydraulic cylinder 42 is fixedly connected to the upper side of the transmission box 41 . Five slots are evenly arranged inside the rotating disk 47 . The uppermost slot of the rotating disk 47 is aligned with the output end of the first hydraulic cylinder 42 .

[0070] Specifically, the extension and retraction of the output end of the first hydraulic cylinder 42 is used to push the welded thermocouple out of the slot, and the interior of the turntable 47 is used to place five different types of thermocouples, namely S-type thermocouple, K-type thermocouple, E-type thermocouple, J-type thermocouple and T-type thermocouple.

[0071] S-type thermocouples are suitable for compensating wires with SPC (copper) as the positive electrode and SNC (copper-nickel) as the negative electrode, and the insulation layer is colored red and green respectively.

[0072] K-type thermocouples are suitable for compensating wires with KPC (lead) for the positive electrode and KNC (copper-nickel) for the negative electrode, and the insulation layer is colored red and blue respectively.

[0073] Type E thermocouples are suitable for compensating wires with EPX (nickel-chromium) for the positive electrode and ENX (copper-nickel) for the negative electrode, and the insulation layer is colored red and brown respectively.

[0074] J-type thermocouples are suitable for compensating wires with JPX (iron) for the positive electrode and JNX (copper-nickel) for the negative electrode, and the insulation layer is colored red and purple respectively.

[0075] T-type thermocouples are suitable for compensating wires with TPX (copper) for the positive electrode and TNX (copper-nickel) for the negative electrode, and the insulation layer is colored red and white respectively.

[0076] The camera 2 first takes images of the inner core and insulation layer of the different types of compensation wires, and converts the taken photos into electrical signals to be transmitted to the control box 8. A database is provided inside the control box 8, and identification photos of different colors and different numbers of inner cores of the internal insulation layer of the compensation wire are provided inside the database. When the control box 8 receives the photos sent by the camera 2, it will compare them with the identification photos of different colors of the internal insulation layer of the compensation wire in the internal database, and pre-identify the colors of the two insulation layers inside the compensation wire. Based on the obtained photos of the internal insulation layer of the compensation wire, the thermocouple models adapted to the compensation wire are divided into five types: S-type thermocouple, K-type thermocouple, E-type thermocouple, J-type thermocouple, and T-type thermocouple.

[0077] Assuming that the S-type thermocouple is installed at the top of the turntable 47, starting from this, the thermocouple models installed in a clockwise direction are K-type thermocouple, E-type thermocouple, J-type thermocouple and T-type thermocouple, and the angle between every two thermocouples is 72 degrees.

[0078] When the colors of the two insulating layers photographed by camera 2 are red and green respectively, the extension control S-type thermocouple at the output end of the first cylinder 45 moves to the position of welding mechanism 1, and the extension control compensation wire at the output end of the second cylinder 35 moves to the position of welding mechanism 1, and welding mechanism 1 welds the S-type thermocouple and the compensation wire.

[0079] When the colors of the two insulating layers photographed by the camera 2 are red and blue respectively, the output end of the first motor 44 rotates, and the control turntable 47 rotates seventy-two degrees. At this time, the K-type thermocouple is located at the top of the turntable 47, and the extension of the output end of the first cylinder 45 controls the K-type thermocouple to move to the position of the welding mechanism 1. The extension of the output end of the second cylinder 35 controls the compensation wire to move to the position of the welding mechanism 1. The welding mechanism 1 welds the K-type thermocouple and the compensation wire.

[0080] When the colors of the two insulating layers photographed by the camera 2 are red and brown respectively, the output end of the first motor 44 rotates to control the turntable 47 to rotate one hundred and forty-four degrees. At this time, the E-type thermocouple is located at the top of the turntable 47, and the extension of the output end of the first cylinder 45 controls the E-type thermocouple to move to the position of the welding mechanism 1. The extension of the output end of the second cylinder 35 controls the compensation wire to move to the position of the welding mechanism 1. The welding mechanism 1 welds the E-type thermocouple and the compensation wire.

[0081] When the colors of the two insulating layers photographed by the camera 2 are red and purple respectively, the output end of the first motor 44 rotates, and the control turntable 47 rotates 216 degrees. At this time, the J-type thermocouple is located at the top of the turntable 47, and the extension of the output end of the first cylinder 45 controls the J-type thermocouple to move to the position of the welding mechanism 1. The extension of the output end of the second cylinder 35 controls the compensation wire to move to the position of the welding mechanism 1, and the welding mechanism 1 welds the J-type thermocouple and the compensation wire.

[0082] When the colors of the two insulating layers photographed by the camera 2 are red and white respectively, the output end of the first motor 44 rotates to control the turntable 47 to rotate 288 degrees. At this time, the T-type thermocouple is located at the top of the turntable 47, and the extension of the output end of the first cylinder 45 controls the T-type thermocouple to move to the position of the welding mechanism 1. The extension of the output end of the second cylinder 35 controls the compensation wire to move to the position of the welding mechanism 1. The welding mechanism 1 welds the T-type thermocouple and the compensation wire.

[0083] The color of the insulation layer of the compensation wire is photographed by the camera 2 to determine the type of thermocouple compatible with the compensation wire, and the turntable 47 is controlled to rotate a specified degree, so that the thermocouple compatible with the compensation wire is moved to the top of the turntable 47. The first cylinder 45 and the second cylinder 35 respectively control the compatible thermocouple and the compensation wire to move to the position of the welding mechanism 1 for welding, thereby achieving the effects of automatic adaptation of the thermocouple compensation wire and high welding accuracy, avoiding incorrect selection of thermocouples and compensation wires, and indirectly causing the welded thermocouple compensation wires to be scrapped, resulting in production waste.

[0084] Embodiment three, the inner core of the compensation wire can be divided into a single large-diameter inner core and multiple small-diameter inner cores according to the size of resistance and conductivity. Usually, the large-diameter inner core is directly pressed and welded with the connecting column of the thermocouple, and the small-diameter inner core is twisted on the outside of the connecting column of the thermocouple for welding. The existing thermocouple compensation wire welding equipment can only directly press and weld a single large-diameter inner core with the thermocouple connecting column, and cannot automatically twist multiple small-diameter inner cores on the outside of the thermocouple connecting column before welding. Manual twisting is required, resulting in too slow twisting of the small-diameter inner core and low welding efficiency of the thermocouple compensation wire. Therefore, the following structure is designed to solve the above technical problems.

[0085] See also Figure 6 The welding mechanism 1 includes a support seat 19, which is fixedly connected to the upper side of the work table 7. A support frame 18 is fixedly connected to the upper side of the support seat 19. A second hydraulic cylinder 17 is fixedly connected to the interior of the support frame 18. A first support column 11 is fixedly connected to one side of the support frame 18. An upper electrode 12 is fixedly connected to one end of the first support column 11. A connecting rod 16 is hinged to the output end of the second hydraulic cylinder 17. A second support column 15 is hinged to the other end of the connecting rod 16. The upper side of the second support column 15 is hinged to the support frame 18. A lower electrode 14 is fixedly connected to one end of the second support column 15. An inner core twisting assembly 13 is provided on one side of the upper electrode 12 and the lower electrode 14.

[0086] Specifically, the extension of the output end of the second hydraulic cylinder 17 is used to control the second support column 15 to swing upward, so that the lower electrode 14 is close to the upper electrode 12 to perform welding processing on the thermocouple and the compensation wire.

[0087] See also Figure 7 The inner core twisting assembly 13 includes a hanging plate 131, which is fixedly connected to one side of the first support column 11.

[0103] When the inner core of the compensation wire photographed by the camera 2 is a single wire, the control box 8 determines that the connection method between the compensation wire and the thermocouple is compression welding, and the control module controls the output end of the second motor 1342 to rotate counterclockwise one hundred and eighty degrees to avoid the travel distance of the compensation wire and prevent the triangular guide block 1344 from interfering with the compensation wire. At this time, the first pressing tooth 1347 and the triangular guide block 1344 are in the same horizontal plane, and the control module controls the extension of the output end of the first cylinder 45 to control the thermocouple to move to the position of the welding mechanism 1, and the extension of the output end of the second cylinder 35 to control the compensation wire to move to the position of the welding mechanism 1, and the two ends are pressed tightly, and the welding mechanism 1 performs compression welding on the T-type thermocouple and the compensation wire.

In the initial state, the first pressing tooth 1347 is higher than the triangular guide block 1344, and the triangular guide block 1344 is facing the inner core of the compensation wire. The control module controls the extension of the output end of the second cylinder 35 to control the movement of the compensation wire. The tip of the triangular guide block 1344 is inserted into the interior of the multiple inner cores to divide the multiple inner cores into two strands of inner cores until the tip of the triangular guide block 1344 squeezes the insulation layer of the multiple inner cores. At this time, both ends of the two inner cores move to the first In the middle of the core pressing groove 93 and the second core pressing groove 96, the output end of the third hydraulic cylinder 1355 is fully extended, and the output end of the second motor 1342 rotates 360 degrees counterclockwise, and the first pressing tooth 1347 and the second pressing tooth 1352 are combined. At the same time, the two first core pressing grooves 93 and the two second core pressing grooves 96 press the two strands of multiple inner cores to tighten them, and the internal semicircular arc grooves of the first pressing tooth 1347 and the second pressing tooth 1352 are combined to form a through hole, and the triangular guide block 1344 is raised to the top to prevent the two strands of inner cores from being interfered by the triangular guide block 1344 when they are twisted and rotated.

After the twisting is completed, the control module controls the output end of the second motor 1342 to rotate one hundred and eighty degrees clockwise, and the output end of the third hydraulic cylinder 1355 retracts halfway. At this time, the first pressing tooth 1347 and the second pressing tooth 1352 are away from each other, and the first pressing tooth 1347 and the second pressing tooth 1352 are no longer combined. The first pressing tooth 1347 and the triangular guide block 1344 are in the same horizontal plane, avoiding the travel distance of the inner core and the connection column.

When multiple inner cores are twisted, the first pressing tooth 1347 is controlled to move up and down, which can not only press the two inner cores for subsequent twisting work, but also indirectly control the triangular guide block 1344 to move upward, avoiding the rotation space of the two inner cores, and preventing the two inner cores from being interfered by the triangular guide block 1344 when they are twisted and rotated.
