Description

Technical Field

[0001] This utility model relates to the field of nickel sheet processing technology, specifically to an automatic nickel sheet cutting and welding equipment. Background Technology

[0002] To meet production needs, nickel sheets are welded onto a substrate, such as a copper sheet. Existing welding processes require cutting first, followed by a pre-pressing process to press the nickel sheet onto the substrate surface before final welding. This method necessitates switching between cutting, pre-pressing, and welding stations, resulting in a long processing cycle and low efficiency. Utility Model Content

[0003] In view of this, the present invention provides an automatic nickel sheet cutting and welding equipment to solve the problem of low processing efficiency caused by station switching in the prior art.

[0004] This utility model provides an automatic nickel sheet cutting and welding device for welding nickel sheets onto a substrate, comprising:

[0005] Nickel sheet feeding mechanism, suitable for conveying nickel sheets to the processing position;

[0006] A substrate feeding mechanism, suitable for conveying substrates to the processing station;

[0007] A nickel sheet pre-pressing mechanism includes a pre-pressing cylinder and a pressure plate, wherein the pre-pressing cylinder is adapted to drive the pressure plate to pre-press the nickel sheet onto the surface of the substrate;

[0008] A cutting and welding mechanism suitable for cutting and welding nickel sheets on the surface of a substrate;

[0009] The pressure plate is provided with cutting holes and welding holes, and the cutting and welding mechanism performs cutting and welding operations through the cutting holes and welding holes respectively.

[0010] In this application, the cutting, pre-pressing, and welding processes are integrated into a single station through the coordinated design of cutting and welding holes on the pressure plate. This eliminates the need for station switching, reducing the low processing efficiency caused by such switching. The pre-pressing cylinder drives the pressure plate to firmly press the nickel sheet against the substrate surface, ensuring no displacement of the nickel sheet before cutting and welding. The cutting holes precisely define the laser cutting range, preventing damage to the copper substrate. The welding holes constrain the weld point position, concentrating laser energy on the target area and significantly improving welding consistency. This integrated structure eliminates the need for separate cutting fixtures and positioning modules in traditional processes, reducing equipment space requirements and mechanical linkage errors. Furthermore, since cutting and welding are completed continuously after the pressure plate is pressed once, the nickel sheet does not require secondary positioning, completely eliminating the risk of nickel sheet detachment or displacement caused by transfer in traditional processes. This is particularly suitable for the high-precision processing requirements of ultra-thin nickel sheets.

[0011] In one alternative implementation, it further includes:

[0012] A reel, suitable for mounting nickel sheet rolls;

[0013] The nickel sheet feeding mechanism is connected to the end of the nickel sheet roll and is suitable for conveying the nickel sheet to the processing position.

[0014] In this application, the reel-mounted nickel sheet roll enables a continuous supply of nickel sheet raw materials, breaking through the efficiency bottleneck of traditional single-sheet feeding. The nickel sheet roll is continuously pulled to the processing position by the nickel sheet feeding mechanism, avoiding downtime caused by frequent manual replacement of nickel sheets, and is particularly suitable for large-scale production scenarios.

[0015] In one optional embodiment, the nickel sheet feeding mechanism includes:

[0016] The first clamping cylinder and the second clamping cylinder are arranged sequentially along the feeding direction;

[0017] The feeding cylinder is adapted to drive the first clamping cylinder to reciprocate along the feeding direction;

[0018] The first clamping cylinder and the second clamping cylinder alternately perform clamping or releasing actions on the end of the nickel sheet roll, and the first clamping cylinder performs clamping action when moving toward the feeding direction and releasing action when moving away from the feeding direction.

[0019] In this application, a first clamping cylinder, a second clamping cylinder, and a feeding cylinder enable high-precision intermittent feeding of nickel sheets. When the first clamping cylinder advances under the drive of the feeding cylinder, it clamps the nickel sheet, pushing it precisely to the processing position; when retracting, it releases the nickel sheet, which is then clamped by the second clamping cylinder, forming a "grab-push-release-receive" cyclic action chain. This mechanism eliminates inertial deviations caused by the continuous movement of the lead screw module, especially ensuring the positional stability of the nickel sheet during high-speed feeding. The alternating clamping action ensures that the nickel sheet is always constrained by at least one cylinder, preventing warping caused by feeding jitter. Compared to traditional roller feeding, the cylinder clamping force can be dynamically adjusted according to the thickness of the nickel sheet, preventing deformation or slippage.

[0020] In one optional embodiment, the nickel sheet feeding mechanism further includes a shaping component, the shaping component comprising:

[0021] Two shaping rollers with a gap for shaping, through which the nickel sheet passes;

[0022] The shaping channel for the nickel sheet to pass through is located between the shaping roller and the roll, and its cross-section is adapted to the shape of the nickel sheet.

[0023] In this application, the forming rollers and forming channel specifically address the deformation recovery problem of coiled nickel sheets. As the nickel sheet passes through the gap between the two forming rollers, the roller pressure eliminates the wavy deformation caused by curling stress. Subsequently, upon entering the forming channel with a matching cross-section, the inner wall of the channel applies a uniform constraint force along the width direction of the nickel sheet, correcting lateral bending. The nickel sheet, after two stages of forming, enters the processing position in an absolutely flat state, ensuring complete contact between the nickel sheet and the copper sheet surface when the pre-pressing mechanism presses down. This improves the cross-sectional quality of laser cutting and the uniformity of welding fusion, with particularly significant effects on soft nickel sheets with low yield strength.

[0024] In one optional embodiment, the nickel sheet pre-pressing mechanism includes:

[0025] A connecting structure is provided between the pre-compression cylinder and the pressure plate, and a conveying channel is provided between the connecting structure and the pressure plate;

[0026] The nickel sheet extends through the conveying channel to below the cutting and welding holes.

[0027] In this application, a conveying channel is provided between the pre-pressing cylinder and the pressure plate, integrating the nickel sheet guiding function into the pre-pressing mechanism. The nickel sheet passes through this channel directly to the area below the opening in the pressure plate. The inner wall of the channel forms a sliding constraint on the nickel sheet, ensuring smooth feeding while limiting its horizontal degree of freedom, preventing lateral slippage of the nickel sheet when the pre-pressing cylinder presses down. This structure simplifies the equipment layout, eliminates the need for an independent guiding module, and shortens the length of the suspended section of the nickel sheet from the feeding endpoint to the processing position, eliminating positioning deviations caused by the thin nickel sheet sagging due to its own weight.

[0028] In one alternative embodiment, the pressure plate has a protrusion that protrudes from the connecting structure, and both the cutting hole and the welding hole are provided on the protrusion.

[0029] In this application, space can be left below the protrusion for the substrate to enter the processing position, so that the substrate can reach the position below the end of the nickel sheet roll, which facilitates the pre-pressing of the end of the nickel sheet roll onto the surface of the substrate.

[0030] In one optional embodiment, the nickel sheet feeding mechanism includes:

[0031] Both the first and second feeding modules are connected to tooling fixtures;

[0032] The first feeding module and the second feeding module move alternately to the processing position to achieve uninterrupted loading and unloading.

[0033] The first and second feeding modules, equipped with tooling fixtures, work alternately to create a continuous production flow. While the substrate in the fixture of the first feeding module is being welded at the processing station, the second feeding module simultaneously removes the finished product and loads new material at the loading / unloading station; the two modules immediately exchange positions after welding is completed. This design eliminates the waiting period for manual loading and unloading, maximizing the processing efficiency of the equipment.

[0034] In one optional embodiment, the nickel sheet feeding mechanism further includes:

[0035] A side-shifting cylinder is disposed between the tooling fixture and the first feeding module, and between the tooling fixture and the second feeding module, for adjusting the alignment of the tooling fixture with the processing position.

[0036] In this application, a lateral displacement cylinder serves as a secondary adjustment mechanism between the tooling fixture and the feeding module, resolving the positioning deviation problem caused by the linear movement of the first and second feeding modules along the feeding direction. When the feeding module moves the tooling fixture near the processing position, the lateral displacement cylinder pushes the fixture until it is precisely aligned with the processing position. This design overcomes the physical limitations of mechanical positioning accuracy, especially ensuring the precise alignment required for laser welding. The lateral movement is only activated during the final positioning stage and does not interfere with the module.

[0037] In one optional embodiment, the tooling fixture has a loading position for placing the substrate, and a through-beam sensor is provided at the loading position to detect whether the substrate is in place.

[0038] In this application, a through-beam sensor is integrated into the loading position of the tooling fixture to construct a real-time closed-loop verification of the substrate's in-situ status. The sensor's optical path spans the loading area of ​​the fixture; when the substrate is placed, blocking the optical path triggers an in-situ signal.

[0039] In one alternative implementation, it further includes:

[0040] A guide shaft, disposed between the forming channel and the reel, is adapted to guide the nickel sheet to be conveyed along the direction of the forming channel.

[0041] In this application, a guide shaft is added between the forming channel and the roll to achieve a smooth curvature transition of the nickel sheet from the roll to the forming channel. The diameter of the guide shaft matches the minimum bending radius of the nickel sheet, avoiding hard creases caused by sudden bending and straightening when the roll is unwound. Its rotational freedom reduces the friction of the nickel sheet during transport, preventing tensile deformation. The nickel sheet can enter the channel at zero angle, eliminating edge curling caused by oblique insertion. Reducing the risk of wrinkles in the nickel sheet is a key auxiliary structure to ensure high yield. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0051] According to embodiments of the present invention, such as Figure 1 As shown, an automatic nickel sheet cutting and welding device is provided for welding nickel sheets onto a substrate, comprising:

[0052] Nickel sheet feeding mechanism, suitable for conveying nickel sheets to the processing position;

[0053] A substrate feeding mechanism, suitable for conveying substrates to the processing station;

[0054] A nickel sheet pre-pressing mechanism includes a pre-pressing cylinder 1 and a pressure plate 2, wherein the pre-pressing cylinder 1 is adapted to drive the pressure plate 2 to pre-press the nickel sheet onto the surface of the substrate.

[0055] The cutting and welding mechanism 23 is suitable for cutting and welding nickel sheets on the surface of a substrate;

[0056] The pressure plate 2 is provided with a cutting hole 3 and a welding hole 4, and the cutting and welding mechanism 23 performs cutting and welding operations through the cutting hole 3 and the welding hole 4 respectively.

[0057] The substrate feeding mechanism can be set on the first worktable 5, and the nickel sheet feeding mechanism and the nickel sheet pre-pressing mechanism can be set on the second worktable 6. The second worktable 6 is connected and set above the first worktable 5.

[0058] Specifically, the pressure plate 2 of the nickel sheet pre-pressing mechanism can be designed as a multi-degree-of-freedom flexible hinge structure, and its pressing trajectory is controlled in real time by the three-dimensional morphology of the substrate surface. The laser head of the cutting and welding mechanism 23 is motion-coupled with the pressure plate 2—when the pressure plate 2 contacts the nickel sheet, the laser head synchronously scans the substrate surface to generate a topological map, and the pre-pressing cylinder 1 dynamically adjusts the pressure distribution of each hinge node according to the topological data, so that the pressure plate 2 undergoes adaptive deformation, ensuring that the nickel sheet completely conforms to the curved substrate. This can break through the limitations of traditional planar pre-pressing and solve the problem of incomplete welding of nickel sheets on curved substrates. Dynamic pressure distribution eliminates local suspension caused by uneven substrates and avoids vibration of the nickel sheet during laser cutting; the welding hole 4 matches the normal angle of the welding point when the pressure plate 2 deforms, ensuring the consistency of the weld depth on irregular structures. The flexible hinge replacing the mechanical guide rail also reduces mechanism wear and extends equipment life.

[0059] The nickel sheet feeding mechanism can be arranged with an orthogonal electromagnetic array along the processing path. The nickel sheet is suspended and transmitted by a controlled magnetic field, and its position and orientation are precisely guided by the moving electromagnetic wave nodes generated by the array. The tooling fixture 17 of the substrate feeding mechanism has a built-in ferromagnetic positioning layer. When the nickel sheet is suspended to the processing position, the nickel sheet pre-pressing mechanism is energized to generate a transient strong magnetic field in the pressure plate 2, which attracts and positions the nickel sheet onto the substrate surface. Subsequently, the cutting and welding mechanism 23 performs the operation. Non-contact feeding completely eliminates scratches or deformation of the nickel sheet caused by mechanical clamping, and is suitable for ultra-thin nickel sheets. Electromagnetic levitation enables six-degree-of-freedom fine adjustment of the nickel sheet, with position control accuracy down to the micrometer level; transient magnetic pre-pressing avoids the impact vibration of traditional cylinders, ensuring the welding reliability of precision electronic components.

[0060] In this application, the cutting hole 3 and welding hole 4 on the pressure plate 2 are designed in a coordinated manner to integrate cutting, pre-pressing, and welding into one station, eliminating the need for station switching and reducing the low processing efficiency caused by station switching. The pre-pressing cylinder 1 drives the pressure plate 2 to press the nickel sheet tightly against the substrate surface, ensuring that the nickel sheet does not shift before cutting and welding. The cutting hole 3 can precisely limit the laser cutting range to avoid damage to the copper substrate. The welding hole 4 can constrain the position of the weld point, allowing the laser energy to be concentrated on the target area, significantly improving welding consistency. This integrated structure eliminates the need for separate cutting fixtures and positioning modules in traditional processes, reducing equipment space occupation and mechanical linkage errors. At the same time, since cutting and welding are completed continuously after the pressure plate 2 is pressed once, the nickel sheet does not need secondary positioning, completely eliminating the risk of nickel sheet falling off or shifting due to transfer in traditional processes, which is especially suitable for the high-precision processing requirements of ultra-thin nickel sheets.

[0061] In one alternative implementation, it further includes:

[0062] Reel 7, suitable for mounting nickel sheet reel 8;

[0063] The nickel sheet feeding mechanism is connected to the end of the nickel sheet roll 8 and is suitable for conveying the nickel sheet to the processing position.

[0064] A column can be installed on the first worktable 5, and a third worktable 27, a reel 7, and a cutting and welding mechanism 23 can be mounted on the column. The third worktable 27 is located above the second worktable 6. The cutting and welding mechanism 23 can be divided into a cutting device and a welding device. The cutting device cuts the nickel sheet roll 8 pre-pressed onto the base surface through the cutting hole 3, and the welding device welds the nickel sheet onto the base material through the welding hole 4. The cutting device can be a laser cutter.

[0065] Specifically, the spool 7 is rotatably connected to the mechanism fixing plate, which is connected to the third worktable 27. A friction adjustment knob 24 can also be installed on the mechanism fixing plate, screwed onto it and abutting against the spool 7. Turning the friction adjustment knob 24 adjusts the contact strength between it and the spool 7, thereby adjusting the tension required to rotate the nickel sheet roll 8, ensuring the roll 8 is straightened when unwound. An intermediate structure can be provided between the friction adjustment knob 24 and the spool 7, allowing for indirect contact. Two limiting plates 25 can also be fitted onto the spool 7, with the nickel sheet roll 8 positioned between them. A nickel sheet fixing plate 26 can be installed at the end of the spool 7 furthest from the mechanism fixing plate to prevent the nickel sheet roll 8 from detaching from the limiting plate 25.

[0066] In this application, the installation of nickel sheet roll 8 on the reel 7 enables continuous supply of nickel sheet raw materials, breaking through the efficiency bottleneck of traditional single-sheet feeding. The nickel sheet roll 8 is continuously pulled to the processing position by the nickel sheet feeding mechanism, avoiding downtime caused by frequent manual replacement of nickel sheets, which is especially suitable for large-scale production scenarios.

[0067] In one optional embodiment, the nickel sheet feeding mechanism includes:

[0068] The first clamping cylinder 9 and the second clamping cylinder 10 are arranged sequentially along the feeding direction;

[0069] The feeding cylinder is adapted to drive the first clamping cylinder 9 to reciprocate along the feeding direction; the first clamping cylinder 9 can be disposed between the second clamping cylinder 10 and the pressure plate 2, and the feeding cylinder and the second clamping cylinder 10 can be fixed on the second worktable 6.

[0070] The first clamping cylinder 9 and the second clamping cylinder 10 can be double-arm cylinders, which complete the clamping or releasing action through the double arms. The first clamping cylinder 9 is connected to the feeding cylinder, as shown in the figure. The two arms of the first clamping cylinder 9 and the second clamping cylinder 10 can open and close up and down. The feeding cylinder can drive the first clamping cylinder 9 to reciprocate towards the processing position.

[0071] The first clamping cylinder 9 and the second clamping cylinder 10 alternately perform clamping or releasing actions on the end of the nickel sheet roll 8. The first clamping cylinder 9 performs clamping action when moving toward the feeding direction and releasing action when moving away from the feeding direction.

[0072] In this application, the first clamping cylinder 9, the second clamping cylinder 10, and the feeding cylinder enable high-precision intermittent feeding of nickel sheets. When the first clamping cylinder 9 advances under the drive of the feeding cylinder, it clamps the nickel sheet, pushing it precisely to the processing position; when it retracts, it releases the nickel sheet, which is then clamped by the second clamping cylinder 10, forming a "grab-push-release-receive" cyclic action chain. This mechanism eliminates inertial deviations caused by the continuous movement of the lead screw module, especially ensuring the positional stability of the nickel sheet during high-speed feeding. The alternating clamping action ensures that the nickel sheet is always constrained by at least one cylinder, preventing warping caused by feeding jitter. Compared to traditional roller feeding, the cylinder clamping force can be dynamically adjusted according to the thickness of the nickel sheet, preventing deformation or slippage.

[0073] In one alternative implementation, such as Figure 2 As shown, the nickel sheet feeding mechanism further includes a shaping component, which includes;

[0074] Two shaping rollers 11 have gaps for shaping, through which nickel sheets pass; the shaping rollers 11 can be connected to the second worktable 6 via columns, and the columns are fixedly connected to the second worktable 6. Columns are rotatably mounted at both ends of the shaping rollers 11.

[0075] A shaping channel for the nickel sheet to pass through is located between the shaping roller 11 and the roll 7, and its cross-section is adapted to the shape of the nickel sheet. Two interlocking cover plates 12 can be fixedly installed on the second worktable 6, forming a shaping channel between the cover plates 12, which is opened along the feeding direction. The end of the nickel sheet roll 8 enters between the two arms of the second clamping cylinder 10 after passing through the shaping roller 11. The outlet end of the shaping channel is aligned with the inlet end of the shaping roller 11. The outlet end of the shaping roller 11 is aligned with the inlet end of the second clamping cylinder 10, and the outlet end of the second clamping cylinder 10 is aligned with the inlet end of the first clamping cylinder 9.

[0076] In this application, the forming rollers 11 and the forming channel specifically address the deformation recovery problem of coiled nickel sheets. When the nickel sheet passes through the gap between the two forming rollers 11, the roller pressure eliminates the wavy deformation caused by curling stress. Subsequently, after entering the forming channel with a matching cross-section, the inner wall of the channel applies a uniform constraint force to the width direction of the nickel sheet, correcting lateral bending. The nickel sheet, after two stages of forming, enters the processing position in an absolutely flat state, ensuring complete contact between the nickel sheet and the copper sheet surface when the pre-pressing mechanism presses down. This improves the cross-sectional quality of laser cutting and the uniformity of welding fusion, especially for soft nickel sheets with low yield strength.

[0077] In one alternative implementation, such as Figure 3 As shown, the nickel sheet pre-pressing mechanism includes:

[0078] A connecting structure 13 is disposed between the pre-compression cylinder 1 and the pressure plate 2, and a conveying channel is provided between the connecting structure 13 and the pressure plate 2. The pre-compression cylinder 1 can be connected to the second worktable 6, and the pre-compression cylinder 1 can drive the connecting structure 13 and the pressure plate 2 to perform up-and-down reciprocating motion. The conveying channel is opened along the feeding direction, and the end of the nickel sheet roll 8 enters the conveying channel after passing through the first clamping cylinder 9. The outlet end of the first clamping cylinder 9 is aligned with the inlet end of the conveying channel.

[0079] The nickel sheet, i.e. the end of the nickel sheet roll 8, extends through the conveying channel to below the cutting hole 3 and the welding hole 4.

[0080] In this application, a conveying channel is provided between the pre-pressing cylinder 1 and the pressure plate 2, which integrates the nickel sheet guiding function into the pre-pressing mechanism. The nickel sheet passes through this channel directly to the opening below the pressure plate 2. The inner wall of the channel forms a sliding constraint on the nickel sheet, ensuring smooth feeding while restricting its horizontal degree of freedom, thus preventing lateral slippage of the nickel sheet when the pre-pressing cylinder 1 presses down. This structure simplifies the equipment layout, eliminates the need for an independent guiding module, and shortens the length of the suspended section of the nickel sheet from the feeding end point to the processing position, eliminating positioning deviations caused by the thin nickel sheet sagging due to its own weight.

[0081] In one optional embodiment, the pressure plate 2 has a protrusion 14 that protrudes from the connecting structure 13, and both the cutting hole 3 and the welding hole 4 are provided on the protrusion 14. The area below the protrusion 14 is a processing position.

[0082] In this application, space is provided below the protrusion 14 for the substrate to enter the processing position, so that the substrate can reach the position below the end of the nickel sheet roll 8, which facilitates the pre-pressing of the end of the nickel sheet roll 8 onto the surface of the substrate.

[0083] In one alternative implementation, such as Figure 4 As shown, the nickel sheet feeding mechanism includes:

[0084] The first feeding module 15 and the second feeding module 16 are both connected to the tooling fixture 17; the base material is set on the tooling fixture 17.

[0085] The first feeding module 15 and the second feeding module 16 move alternately to the processing position to achieve uninterrupted loading and unloading.

[0086] The first feeding module 15 and the second feeding module 16, carrying the tooling fixture 17, work alternately to create a continuous production flow. When the substrate in the fixture of the first feeding module 15 is being welded at the processing station, the second feeding module 16 simultaneously performs finished product removal and new material loading at the loading and unloading station; after welding is completed, the two modules immediately exchange positions. This design eliminates the waiting period for manual loading and unloading, maximizing the processing efficiency of the equipment.

[0087] Specifically, the first feeding module 15 and the second feeding module 16 can drive the tooling fixture 17 to move linearly toward the processing position, so that the substrate on the tooling fixture 17 is close to the processing position. Alternatively, the second worktable 6 can move linearly toward the tooling fixture 17.

[0088] In one optional embodiment, the nickel sheet feeding mechanism further includes:

[0089] The side-shifting cylinder 18 is disposed between the tooling fixture 17 and the first feeding module 15, and between the tooling fixture 17 and the second feeding module 16, for adjusting the alignment state between the tooling fixture 17 and the processing position.

[0090] Specifically, when the first feeding module 15 moves the tooling fixture 17 close to the processing position, there is a positioning deviation between the tooling fixture 17 and the processing position. This deviation can be eliminated by using the lateral displacement cylinder 18 to move the tooling fixture 17 laterally toward the processing position, allowing the first feeding module 15 to continue moving the tooling fixture 17 to the processing position. The second worktable 6 can be equipped with positioning pins 19 facing the tooling fixture 17. The tooling fixture 17 can be equipped with matching positioning holes. When the tooling fixture 17 moves to the processing position, the positioning pins 19 are inserted into the positioning holes for further precise positioning. This is the loading process.

[0091] After processing is completed, the first feeding module 15 moves the tooling fixture 17 away from the processing position, then moves it in the opposite direction, and finally moves it to the loading position for manual removal of the processed product and loading. This is the unloading process. At the same time, the second feeding module 16 performs the loading process.

[0092] In this application, the lateral displacement cylinder 18 serves as a secondary adjustment mechanism between the tooling fixture 17 and the feeding module, resolving the positioning deviation problem caused by the linear movement of the first feeding module 15 and the second feeding module 16 along the feeding direction. When the feeding module moves the tooling fixture 17 to the vicinity of the processing position, the lateral displacement cylinder 18 pushes the fixture until it is precisely aligned with the processing position. This design overcomes the physical limitations of mechanical positioning accuracy, especially ensuring the precise alignment required for laser welding. The lateral movement is only activated during the final positioning stage and does not interfere with the module.

[0093] In one optional embodiment, the tooling fixture 17 has a loading position 20 for placing the substrate, and a through-beam sensor 21 is provided at the loading position 20 to detect whether the substrate is in place. The substrate can be inserted into the loading position 20. If the through-beam sensor 21 does not detect the material, loading may not have been performed, or the material may be tilted, and an alert can be issued. The end of the feeding module away from the processing position can be the loading / unloading point, where loading or unloading can be performed manually.

[0094] In this application, the loading position 20 of the tooling fixture 17 integrates a through-beam sensor 21 to construct a real-time closed-loop verification of the substrate's in-situ status. The sensor's optical path spans the loading area of ​​the fixture; when the substrate is placed, blocking the optical path triggers an in-situ signal.

[0095] In one alternative implementation, it further includes:

[0096] A guide shaft 22, disposed between the forming channel and the reel 7, is adapted to guide the nickel sheet to be conveyed along the direction of the forming channel. The guide shaft 22 can be rotatably connected to the second worktable 6 via a connecting plate.

[0097] In this application, a guide shaft 22 is added between the forming channel and the roll 7 to achieve a smooth curvature transition of the nickel sheet from the roll to the forming channel. The diameter of the guide shaft 22 matches the minimum bending radius of the nickel sheet, avoiding hard creases caused by sudden bending and straightening when the roll is unwound. Its rotational freedom reduces the friction of the nickel sheet during transport, preventing tensile deformation. The nickel sheet can enter the channel at zero angle, eliminating edge curling caused by oblique insertion. Reducing the risk of wrinkles in the nickel sheet is a key auxiliary structure to ensure high yield.

[0098] In this application, the cylinder and the feeding module can be controlled by a program, thus ensuring that the nickel sheets welded on the substrate are of the same size.

[0099] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
