Description

Technical Field

[0001] This application relates to the field of welding technology, and more specifically, to a welding heating device and production line. Background Technology

[0002] In related technologies, workpieces are typically preheated to a certain temperature before welding to improve welding efficiency. A common heating method is the use of electric heaters such as heating rods. During use, the heating rod needs to be continuously powered and kept close to or in contact with the workpiece, moving with it to the welding station to ensure the workpiece reaches the welding position and is kept at a certain temperature for direct welding. However, this movement of the heating rod's power cord also causes considerable inconvenience. Summary of the Invention

[0003] In view of this, this application provides a welding heating device and production line to solve the technical problem that traditional heating rods need to move to the welding station along with the workpiece to heat it.

[0004] One embodiment of this application provides a welding heating apparatus. The welding heating apparatus includes a heater and a carrier. The carrier is configured to move relative to the heater. The carrier includes a heating seat. The heating seat is configured to hold a workpiece and to be in thermal contact with the workpiece. The heater is capable of heating the heating seat so that the heating seat heats the workpiece to a temperature greater than or equal to a set temperature.

[0005] The heating seat supports the workpiece and makes thermal contact with it. After the heater heats the heating seat, it separates from the heating seat, allowing the carrier to carry the workpiece to the welding station. The heating seat transfers heat to the workpiece, ensuring that it reaches the welding station at least at a set temperature for subsequent welding. The heater only needs to heat the heating seat at a fixed station and does not need to move with the carrier and workpiece to the welding station. This application uses indirect heating to heat the workpiece to a set temperature or above, after which the heater can separate from the workpiece. The workpiece, under the insulation of the heating seat, effectively reduces heat loss and decreases continuous dependence on the heater. Simultaneously, the heater focuses on heating the heating seat, while the carrier can transfer the workpiece to the welding station, effectively improving welding efficiency and facilitating multi-process, multi-station production lines.

[0006] In some embodiments of this application, the heater includes an electromagnetic induction head. The heating base is made of a conductive material. The electromagnetic induction head is located inside the heating base. The electromagnetic induction head is configured to be powered by a power source, causing the energized electromagnetic induction head to generate an alternating magnetic field, thereby heating the heating base.

[0007] The heater indirectly heats the workpiece using electromagnetic induction heating. When a high-frequency alternating current is applied to the electromagnetic induction head, eddy currents are generated inside the heating element. The heating element heats up rapidly under the influence of the high-frequency alternating magnetic field, and the heat is then transferred to the workpiece until it reaches a temperature greater than or equal to a preset temperature. The heating rate can be increased by changing the frequency of the alternating current, thereby improving heating efficiency.

[0008] In some embodiments of this application, the heating base is provided with an induction heating cavity. An electromagnetic induction head is configured to enter and exit the induction heating cavity in a first direction. When the electromagnetic induction head is located within the induction heating cavity, the cavity wall surrounds the electromagnetic induction head.

[0009] The cavity wall of the induction heating chamber surrounds the electromagnetic induction head, and the heating seat forms a closed ring along a cross section perpendicular to the first direction to create a relatively closed electromagnetic field environment and improve the efficiency of electromagnetic induction heating.

[0010] In some embodiments of this application, the induction heating cavity extends through opposite sides of the heating base along a first direction. Along a direction perpendicular to the first direction, the projection of the heating base overlaps the projection of the electromagnetic induction head.

[0011] The induction heating cavity is used to generate eddy currents in the electromagnetic induction head, and the upper surface of the heating seat is generally used to support the workpiece. By extending the induction heating cavity through opposite sides of the heating seat along a first direction, more of the eddy currents generated inside the heating seat can be used to heat the parts closest to the workpiece, thereby improving the efficiency of electromagnetic induction heating. Furthermore, along a direction perpendicular to the first direction, the projection of the heating seat covers the projection of the electromagnetic induction head, ensuring that the cavity wall of the induction heating cavity surrounds the electromagnetic induction head.

[0012] In some embodiments of this application, the electromagnetic induction head has a hollow structure. The electromagnetic induction head has a water inlet and a water outlet for allowing cooling water to flow into the interior of the electromagnetic induction head.

[0013] Since the electromagnetic induction head, which acts as the induction coil, is located inside the heating base, when the heating base is heated, it will in turn heat the electromagnetic induction head. Cooling measures help reduce the impact of high temperature on the electromagnetic induction head.

[0014] In some embodiments of this application, the carrier further includes a substrate and a heat insulation element. The heat insulation element is disposed on the substrate and surrounds at least a portion of the exterior of the heating seat to insulate the heating seat from heat.

[0015] By installing heat insulation components to separate the heating base from the carrier and other components on the carrier as much as possible, heat dissipation is limited, allowing heat to be better concentrated on the heating base. This helps ensure that the workpiece remains at or above the set temperature when the carrier reaches the welding station. Simultaneously, the heat insulation components effectively prevent the high-temperature heating base from affecting the carrier and other components, and effectively prevent workers from directly contacting the high-temperature heating base, thus improving safety.

[0016] In some embodiments of this application, the carrier further includes a clamping mechanism. The clamping mechanism is disposed on the heating base. The clamping mechanism is used to clamp the workpiece.

[0017] Setting up a clamping mechanism to hold the workpiece can effectively fix the workpiece on the heating base, which helps to avoid uneven heating caused by workpiece movement or displacement.

[0018] In some embodiments of this application, the clamping mechanism includes a fixing member and an elastic member. The fixing member is disposed on the heating seat and is movable relative to the heating seat. The heating seat includes an abutment portion. The elastic member is used to apply an elastic force to the fixing member to drive the fixing member to move so that the fixing member and the abutment portion clamp the workpiece.

[0019] The elastic force of the elastic element pushes the fixed element closer to the abutment part, thereby clamping the workpiece. Because the elastic force provided by the elastic element has a certain adjustment range, the fixed element can be adjusted in position according to the actual size of the workpiece to accommodate workpieces of different sizes or shapes. Furthermore, the clamping force provided by the elastic element is adjustable, effectively preventing damage to the workpiece surface due to excessive clamping force.

[0020] In some embodiments of this application, the welding heating apparatus further includes an induction element. The induction element is used to sense when the workpiece is heated to a temperature greater than or equal to a set temperature.

[0021] Once the sensor detects that the workpiece has been heated to a temperature greater than or equal to the set temperature, the heater separates from the carrier, and the carrier moves the workpiece to the welding station for the next process.

[0022] In some embodiments of this application, the welding heating apparatus further includes a protective cover. The protective cover is used to cover the carrier.

[0023] When heating the heating seat, the entire carrier and workpiece are covered with a protective cover to reduce the impact of high temperature on other mechanisms around the carrier.

[0024] In some embodiments of this application, the welding heating apparatus further includes a first moving mechanism and a second moving mechanism. A carrier is disposed on the first moving mechanism. The first moving mechanism is used to move the carrier closer to or further away from the heater. The heater is disposed on the second moving mechanism. The second moving mechanism is used to move the heater to heat the heating seat.

[0025] After heating is complete, the second moving mechanism moves the heater away from the carrier, while the first moving mechanism moves the carrier to the welding station. This reduces the probability of workers directly contacting the high-temperature area, further improving operational safety.

[0026] One embodiment of this application provides a production line including a welding heating device.

[0027] In a production line with welding stations, the welding heating device of this application is used to heat the workpiece. After the workpiece is heated at the heating station, the carrier and the heater are separated, and the workpiece goes to the welding station with the carrier. This can reduce the continuous dependence of the workpiece on the heater, which is conducive to setting up multiple stations and multiple processes on the production line and helps to realize the automated operation of the carrier carrying the workpiece to other stations or workstations.

[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0033] The definitions of "first direction", "second direction" and "third direction" are for the purpose of describing the relative positional relationship of related structures, and do not mean that "first direction", "second direction" and "third direction" need to depend on the related structures involved in the above definitions.

[0034] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0035] The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component.

[0037] Embodiments of this application provide a welding heating apparatus. The welding heating apparatus includes a heater and a carrier. The carrier is configured to move relative to the heater. The carrier includes a heating seat. The heating seat is configured to hold a workpiece and to be in thermal contact with the workpiece. The heater is capable of heating the heating seat so that the heating seat heats the workpiece to a temperature greater than or equal to a set temperature.

[0038] The heating seat supports the workpiece and makes thermal contact with it. After the heater heats the heating seat, it separates from the heating seat, allowing the carrier to carry the workpiece to the welding station. The heating seat transfers heat to the workpiece, ensuring that it reaches the welding station at least at a set temperature for subsequent welding. The heater only needs to heat the heating seat at a fixed station and does not need to move with the carrier and workpiece to the welding station. This application uses indirect heating to heat the workpiece to a set temperature or above, after which the heater can separate from the workpiece. The workpiece, under the insulation of the heating seat, effectively reduces heat loss and decreases continuous dependence on the heater. Simultaneously, the heater focuses on heating the heating seat, while the carrier can transfer the workpiece to the welding station, effectively improving welding efficiency and facilitating multi-process, multi-station production lines.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please see Figure 1 One embodiment of this application provides a welding heating apparatus 100. The welding heating apparatus 100 includes a heater 1 and a carrier 2. The carrier 2 is configured to move relative to the heater 1 to a heating position 10 or a welding position (not shown). The carrier 2 includes a heating seat 21. The heating seat 21 is configured to hold a workpiece 3 and to be in thermal contact with the workpiece 3. When the carrier 2 moves to the heating position 10, the heater 1 can heat the heating seat 21 so that the heating seat 21 heats the workpiece 3 to a temperature greater than or equal to a set temperature. As the carrier 2 moves from the heating position 10 to the welding position, the heating seat 21 can transfer heat to the workpiece 3 to maintain the workpiece 3 at a temperature greater than or equal to a set temperature.

[0041] In related technologies, thermal printheads consist of a flexible circuit board, a ceramic sheet, and connectors. During assembly, the ceramic sheet must first be soldered onto the flexible circuit board. To ensure the quality and reliability of the soldering, the ceramic sheet is typically preheated. This is because the ceramic sheet's material properties mean that when suddenly exposed to the high temperatures of soldering, its internal temperature distribution is uneven, easily generating significant thermal stress. This thermal stress can cause cracks or breakage in the ceramic sheet, affecting the quality and performance of the final product. Preheating the ceramic sheet before soldering allows it to gradually heat up to near the soldering temperature, reducing temperature differences and thermal stress caused by rapid heating. Furthermore, preheating the ceramic sheet shortens the actual soldering time, as the parts are already close to the required soldering temperature, thus improving production efficiency and reducing energy consumption.

[0042] In their research, the inventors of this application discovered that current methods of heating ceramic sheets involve direct heating with heating rods. If the heating rod is separated from the ceramic sheet too early, the ceramic sheet cannot maintain the set temperature. Therefore, the heating rod needs to move with the ceramic sheet to the welding position and maintain contact with it. If a multi-station production line needs to be designed, the wiring of the heating rod itself hinders the implementation of multiple stations and processes. Furthermore, a structure is required to ensure that the heating rod maintains relatively stable contact with the workpiece during movement. Therefore, in most cases, only single heating and welding can be performed. Moreover, based on the structure or material of the workpiece itself, some workpieces cannot be repeatedly clamped. If a heating rod is used to directly heat the ceramic sheet, a clamping mechanism is needed to hold the heating rod and the carrier or workpiece during heating; after heating, the heating rod and workpiece need to be separated, and then another clamping mechanism is used at the welding position to hold the workpiece for welding. The workpiece may be repeatedly clamped, which could lead to deformation.

[0043] In this application, the heating seat 21 is used to support the workpiece 3 and can make thermal contact with the workpiece 3. After the heater 1 heats the heating seat 21, it separates from the heating seat 21. During the process of the carrier 2 moving from the heating position 10 to the welding position, the heating seat 21 can transfer heat to the workpiece 3, so that when the workpiece 3 reaches the welding position, it can still maintain at least the set temperature for subsequent welding. The heater 1 only needs to perform heating operations at the heating position 10 and does not need to move with the carrier 2 and the workpiece 3 to the welding position. Compared with the aforementioned direct heating method, which requires the heating rod to be in close contact with the workpiece 3 and move with it, this application uses an indirect heating method to heat the workpiece 3 to the set temperature or above, and the heater 1 can then separate from the workpiece 3. Under the heat preservation effect of the heating seat 21, the workpiece 3 can effectively reduce heat loss and reduce continuous dependence on the heater 1. At the same time, the heater 1 focuses on heating the heating seat 21 at the heating position 10, and the carrier 2 can transfer the workpiece 3 to the welding position, which can effectively improve welding efficiency and facilitate the realization of multi-process, multi-station production lines. The set temperature refers to the temperature that meets the preheating requirements for welding, and it is generally lower than the welding temperature. Understandably, when workpiece 3 reaches the welding position, even if the temperature of workpiece 3 is slightly lower than the set temperature, it still meets the preheating requirements.

[0044] In some embodiments, the set temperature is defined as the temperature that meets the preheating requirements for welding. When the workpiece 3 is a ceramic sheet and a flexible circuit board, the set temperature is 170°C to 190°C.

[0045] In some embodiments, the heater 1 includes an electromagnetic induction head 11. The heating base 21 is made of a conductive material. The electromagnetic induction head 11 is located inside the heating base 21 and is configured to be powered by a power source, so that the energized electromagnetic induction head 11 generates a high-frequency alternating magnetic field, thereby heating the heating base 21.

[0046] Heater 1 indirectly heats workpiece 3 using electromagnetic induction heating. The electromagnetic induction head 11 extends into the heating base 21. When high-frequency alternating current is applied to the electromagnetic induction head 11, the induction head, acting as an induction coil, generates an alternating magnetic field. Eddy currents are generated inside the heating base 21 due to electromagnetic induction, and the magnetic field lines penetrate the heating base 21, causing it to heat up. This heat is then transferred to the workpiece 3 until it reaches a temperature greater than or equal to a preset temperature. Heater 1 uses electromagnetic induction heating to heat the heating base 21. The heating rate of the heating base 21 can be increased by changing the frequency of the alternating current applied to the electromagnetic induction head 11, thereby improving heating efficiency. Understandably, the alternating current frequency should be sufficient to prevent the heating base 21 from melting. In some embodiments, heater 1 can use infrared heating, hot air, or a heating rod to heat the heating base 21, with the appropriate heating method selected based on the material of the heating base 21.

[0047] In some embodiments, the heating base 21 is provided with an induction heating cavity 2101. The electromagnetic induction head 11 is configured to enter and exit the induction heating cavity 2101 along a first direction Y. When the electromagnetic induction head 11 is located inside the induction heating cavity 2101, the cavity wall of the induction heating cavity 2101 surrounds the electromagnetic induction head 11.

[0048] The cavity wall of the induction heating cavity 2101 surrounds the electromagnetic induction head 11, and the heating seat 21 forms a closed ring along a section perpendicular to the first direction Y, so as to form a closed electromagnetic field environment in the direction perpendicular to the first direction Y, thereby improving the efficiency of electromagnetic induction heating.

[0049] Please see Figure 3 and Figure 4 The heating base 21 includes a support member 211 and a carrier member 212. The carrier member 212 is disposed on the support member 211 and is used to support the workpiece 3. Grooves are provided on the opposing surfaces of the support member 211 and the carrier member 212, and the grooves on the support member 211 and the carrier member 212 together form an induction heating cavity 2101. Figure 3 In the illustrated embodiment, the heating base 21 has a through groove along the first direction Y. This through groove is the induction heating cavity 2101. On the plane perpendicular to the first direction Y, the cross-section of the through groove is a closed-loop structure, i.e., a closed ring. It should be noted that the ring here does not simply refer to a circular ring, such as... Figure 3 The shape shown can be a closed rectangle, or a triangle, etc., which can create a relatively closed electromagnetic field environment.

[0050] In some embodiments, the induction heating cavity 2101 extends through opposite sides of the heating base 21 along a first direction Y. Along a direction perpendicular to the first direction Y, the projection of the heating base 21 overlaps the projection of the electromagnetic induction head 11.

[0051] The induction heating cavity 2101 is used to generate eddy currents in the electromagnetic induction head 11, and the upper surface of the heating seat 21 is generally used to support the workpiece 3. The induction heating cavity 2101 extends through opposite sides of the heating seat 21 along the first direction Y. Understandably, after the induction heating cavity 2101 extends through opposite sides of the heating seat 21 along the first direction Y, the heating seat 21 has two openings. For a heating seat 21 with one opening, an eddy current effect is generated inside the heating seat 21. The alternating current generates an alternating magnetic field through the electromagnetic induction head 11, and the magnetic field lines pass through the circumferential sidewalls and bottom wall of the induction heating cavity 2101, causing the heating seat 21 to heat up. Figures 3 to 5 In the illustrated embodiment, the magnetic field lines of the alternating magnetic field in the heating seat 21 pass through the circumferential sidewalls of the induction heating cavity 2101, causing the heating seat 21 to heat up. This allows the alternating magnetic field generated inside the heating seat 21 to be used more extensively to heat areas close to the workpiece 3, thereby improving the efficiency of electromagnetic induction heating. Furthermore, along a direction perpendicular to the first direction Y, the projection of the heating seat 21 covers the projection of the electromagnetic induction head 11, ensuring that the cavity wall of the induction heating cavity 2101 surrounds the electromagnetic induction head 11.

[0052] It should be noted that, assuming the first direction Y is the Y-axis direction, the directions perpendicular to the first direction Y include the X-axis direction and the Z-axis direction. The projection of the heating seat 21 covers the projection of the electromagnetic induction head 11, which helps to improve the heating efficiency of the electromagnetic induction head 11 on the heating seat 21.

[0053] like Figure 2 The electromagnetic induction head 11 shown is a bent arc-shaped structure. In some embodiments, the shape of the electromagnetic induction head 11 can be set to other irregular shapes to improve the electromagnetic induction heating efficiency.

[0054] In some embodiments, the electromagnetic induction head 11 has a hollow structure. The electromagnetic induction head 11 has a water inlet 111 and a water outlet 112 for supplying cooling water into the interior of the electromagnetic induction head 11.

[0055] Since the electromagnetic induction head 11, which serves as the induction coil, is located inside the heating base 21, when the heating base 21 is heated, the heat will also be transferred to the electromagnetic induction head 11. Taking cooling measures helps to reduce the impact of high temperature on the electromagnetic induction head 11.

[0056] In some embodiments, the carrier 2 further includes a substrate 22 and a heat insulation member 23. The heat insulation member 23 is disposed on the substrate 22 and surrounds at least a portion of the exterior of the heating seat 21 to insulate the heating seat 21 from heat.

[0057] The heat insulation component 23 separates the heating base 21 from the carrier 2 and other components on the carrier 2 as much as possible, limiting the outward diffusion of heat and allowing heat to be better concentrated on the heating base 21. This helps ensure that the workpiece 3 is maintained at a temperature greater than or equal to the set temperature when the carrier 2 reaches the welding position. At the same time, the heat insulation component 23 can also effectively prevent the high-temperature heating base 21 from affecting the carrier 2 and other components, and can effectively prevent workers from directly contacting the high-temperature heating base 21, thus improving safety.

[0058] In some embodiments, the carrier 2 further includes a clamping mechanism 4. The clamping mechanism 4 is disposed on the heating base 21. The clamping mechanism 4 is used to clamp the workpiece 3.

[0059] The clamping mechanism 4 is set up to clamp the workpiece 3, which can effectively fix the workpiece 3 on the heating seat 21, which helps to avoid uneven heating caused by the movement or displacement of the workpiece 3.

[0060] Understandably, when workpiece 3 needs to be processed at different workstations or stations, it can be placed on the heating seat 21 and further clamped on the heating seat 21 by the clamping mechanism 4. Whether heating workpiece 3 before welding, welding, or other processing workstations, clamping can be accomplished by the clamping mechanism 4 in this application and its embodiments. In some embodiments of this application, when workpiece 3 is indirectly heated by electromagnetic induction heating, workpiece 3 is placed on the upper surface of the heating seat 21, and the electromagnetic induction head 11 does not need to be fixed to the carrier 2 (or heating seat 21). After heating is completed, the clamping mechanism 4 does not need to be removed, and it still maintains its clamping of workpiece 3. The carrier 2 transports workpiece 3 to the welding position for welding. In this way, the risk of deformation of workpiece 3 due to repeated clamping can be reduced. In some embodiments, the clamping mechanism 4 includes a fixing member 41 and an elastic member 42. The fixing member 41 is provided on the heating seat 21 and can move relative to the heating seat 21. The heating seat 21 includes an abutment portion 2102. The elastic element 42 is used to apply an elastic force to the fixing element 41 to drive the fixing element 41 to move so that the fixing element 41 and the abutment part 2102 clamp the workpiece 3.

[0061] The elastic force of the elastic element 42 can push the fixing element 41 closer to the abutment portion 2102, thereby achieving clamping of the workpiece 3. Since the elastic force provided by the elastic element 42 has a certain adjustment range, the fixing element 41 can adjust its position according to the actual size of the workpiece 3 to adapt to workpieces 3 of different sizes or shapes. Moreover, the clamping force provided by the elastic element 42 is adjustable, which can effectively avoid the problem of damage to the surface of the workpiece 3 due to excessive clamping force.

[0062] In some embodiments, when workpiece 3 is a ceramic sheet of a thermal printhead, please refer to [link to relevant documentation]. Figure 4 and Figure 5The ceramic slabs are square. Of course, ceramic slabs can also be other shapes, such as polygons or triangles.

[0063] In some embodiments, the fixing member 41 includes a main body portion 411, a first limiting portion 412, and a second limiting portion 413. The first limiting portion 412 and the second limiting portion 413 are spaced apart and connected to opposite sides of the main body portion 411. The first limiting portion 412 and the second limiting portion 413 extend in a direction away from the main body portion 411 and are provided with a stop flange 414. The stop flange 414 is configured to prevent the workpiece 3 from disengaging from the fixing member 41. The abutment portion 2102 is located between the main body portion 411 and the stop flange 414. One end of the elastic member 42 is connected to the abutment portion 2102, and the other end of the elastic member 42 abuts against the main body portion 411, thereby compressing the elastic member 42. During installation, the two ends of the elastic element 42 are first compressed between the main body 411 and the abutment portion 2102. The fixing member 41 is then installed onto the heating base 21. A force is then applied to the main body 411 along the first direction Y, further compressing the elastic element 42. This creates space between the stop flange 414 and the abutment portion 2102 for placing a ceramic sheet. The ceramic sheet is then placed with the surface to be welded facing upwards, and the lower surface of the ceramic sheet makes thermal contact with the heating base 21. The main body 411 is then released, and the elastic element 42 applies an elastic force to the main body 411 along the first direction Y, causing the main body 411 to move away from the stop flange 414. This moves the stop flange 414 and abuts against the ceramic sheet. When the ceramic sheet is square, in the first direction Y, the opposite sides of the ceramic sheet are limited by the stop flange 414 and the abutment portion 2102. In the second direction X, which is perpendicular to the first direction Y, the opposite sides of the ceramic sheet are limited by the first limiting portion 412 and the second limiting portion 413.

[0064] In some embodiments, along the third direction Z, both the first limiting portion 412 and the second limiting portion 413 are provided with clamping grooves 415, and the first direction Y, the second direction X, and the third direction Z are perpendicular to each other. In an actual production environment, along the third direction Z, the clamping grooves 415 are configured such that the bottom wall of the clamping grooves 415 is lower than the ceramic sheet. When it is necessary to remove the ceramic sheet from the clamping mechanism 4, a force is applied to the main body portion 411 along the first direction Y, causing the elastic member 42 to be further compressed, the stop flange 414 no longer stops the ceramic sheet, and the robot or other tool for picking up the workpiece 3 removes the ceramic sheet from the clamping mechanism 4 from the position of the clamping grooves 415.

[0065] Please see Figure 3 and Figure 4In some embodiments, the clamping mechanism 4 further includes a connector 43, which is configured to stop the workpiece 3 away from the heating seat 21 along the third direction Z. After the workpiece 3 is clamped in the first direction Y and the second direction X, the connector 43 is placed over the workpiece 3 and the heating seat 21, and the connector 43 and the heating seat 21 are fixed in a detachable manner. When it is necessary to remove the workpiece 3, disassembling the connector 43 will not damage the workpiece 3.

[0066] In some embodiments, the welding heating apparatus 100 further includes an induction element 5. The induction element 5 is used to sense when the workpiece 3 is heated to a temperature greater than or equal to a set temperature. The induction element 5 is disposed at the heating position 10.

[0067] When the sensor 5 detects that the workpiece 3 has been heated to a temperature greater than or equal to the set temperature, the heater 1 separates from the carrier 2, and the carrier 2 moves the workpiece 3 to the welding position to carry out the next process.

[0068] In some embodiments, the welding heating device 100 further includes a protective cover (not shown). The protective cover is used to cover the carrier 2.

[0069] When heating the heating seat 21, the entire carrier 2 and the workpiece 3 are covered with a protective cover to reduce the impact of high temperature on other mechanisms around the carrier 2.

[0070] In some embodiments, the welding heating apparatus 100 further includes a first moving mechanism and a second moving mechanism 6. A carrier 2 is disposed on the first moving mechanism. The first moving mechanism is used to move the carrier 2 to the heating position 10 or the welding position. A heater 1 is disposed on the second moving mechanism 6. The second moving mechanism 6 is used to move the heater 1 to the heating position 10 to heat the heating seat 21.

[0071] After heating is complete, the second moving mechanism 6 moves the heater 1 away from the carrier 2, while the first moving mechanism moves the carrier 2 from the heating position 10 to the welding position. This reduces the probability of workers directly contacting the high-temperature area, further improving operational safety.

[0072] In some embodiments, the second moving mechanism 6 moves only along the first direction Y to move the heater 1 closer to or away from the heating position 10. The second moving mechanism 6 moves along the second direction X, which is perpendicular to the first direction Y. The first moving mechanism and the second moving mechanism 6 can be in the form of a slide rail slider, driven by a motor or a cylinder, and the form is not limited.

[0073] One embodiment of this application provides a production line (not shown in the figure) including a welding heating device 100.

[0074] In a production line with welding stations, the welding heating device 100 of this application is used to heat the workpiece 3. After the workpiece 3 is heated at the heating station, the carrier 2 and the heater 1 are separated. The workpiece 3 goes to the welding station along with the carrier 2. This can reduce the continuous dependence of the workpiece 3 on the heater 1, which is conducive to setting up multiple stations and multiple processes on the production line and helps to realize the automated operation of the carrier 2 carrying the workpiece 3 to other stations or workstations.

[0075] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
