Description

Technical Field

[0001] The invention relates to the field of battery production, in particular to a busbar shaping mechanism. Background Art

[0002] During the junction box installation process, after removing the high-temperature cloth, the busbars need to be shaped to straighten and position them upright for easier junction box installation. Existing shaping mechanisms achieve varying straightening results depending on the busbar. While the straightening effect is adequate for busbars with minimal or no wrinkles, it is less effective for busbars with severe wrinkles, with wrinkles remaining after straightening. This can prevent the wrinkled areas of the busbar from fully aligning with the conductive sheet during welding, resulting in poor welds. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a busbar shaping mechanism, the detailed technical solution of which is as follows:

[0004] A busbar shaping mechanism is used to shape two busbars on a photovoltaic module, the two busbars being a first busbar and a second busbar. The busbar shaping mechanism comprises a lifting module, a mounting bracket, a support assembly, a first shaping assembly, and a second shaping assembly, wherein: the mounting bracket is connected to a driving end of the lifting module; the support assembly is disposed on the mounting bracket, and two back-to-back side surfaces of the support assembly are respectively a first supporting surface and a second supporting surface.

[0005] The first shaping component and the second shaping component are arranged on the mounting bracket and are respectively located on the first side and the second side of the support component, wherein the first shaping component is provided with a first shaping surface facing the first support surface, and a first protrusion protruding outward from the first shaping surface is provided below the first shaping surface; the second shaping component is provided with a second shaping surface facing the second support surface, the second shaping surface is opposite to the first shaping surface, and a second protrusion protruding outward from the second shaping surface is provided below the second shaping surface; the first protrusion and the second protrusion are lower than the support component;

[0006] The lifting module is used to drive the mounting bracket to descend, so that the support assembly is inserted between the two bus bars, and the first shaping assembly and the second shaping assembly are pressed against the photovoltaic assembly; the first shaping assembly is used to press the first bus bar onto the first supporting surface via the first shaping surface, and the first protrusion abuts the root of the first bus bar; the second shaping assembly is used to press the second bus bar onto the second supporting surface via the second shaping surface, and the second protrusion abuts the root of the second bus bar;

[0007] The lifting module is also used to drive the mounting bracket to rise, so as to drive the supporting assembly, the first shaping assembly and the second shaping assembly to straighten the two bus bars upwards.

[0008] The busbar shaping mechanism provided by the present invention has protrusions below the shaping surfaces of the first shaping component and the second shaping component. When the shaping surfaces of the first shaping component and the second shaping component press the two busbars respectively onto the two back-facing support surfaces of the support component, the two protrusions respectively rest against the roots of the corresponding busbars. In this way, when the lifting module drives the support component, the first shaping component and the second shaping component to rise, the shaping surfaces of the first shaping component and the second shaping component cooperate with the support component to straighten the two busbars upward. At the same time, the two protrusions implement secondary straightening of the two busbars. During the secondary straightening process, the two protrusions can stretch out the wrinkles on the busbar, thereby ensuring the straightening effect of the wrinkled busbar.

[0010] The mounting bracket is elastically connected to the first mounting plate via an elastic connector, so that the first shaping component and the second shaping component can be elastically pressed against the photovoltaic component. On the one hand, it can reduce the risk of the photovoltaic component being damaged by pressure, and on the other hand, it ensures that the first shaping component and the second shaping component can move closely against the photovoltaic component toward the corresponding bus bar.

[0012] By arranging the photoelectric sensor and the induction sheet, the first shaping component and the second shaping component are elastically pressed against the photovoltaic component with a predetermined force, thereby preventing the first shaping component and the second shaping component from applying excessive pressure and damaging the photovoltaic component.

[0015] In some embodiments, the first shaping assembly includes a first shaping block driving member and a first shaping block, wherein the first shaping block driving member is installed on the mounting bracket, the first shaping block is connected to the driving end of the first shaping block driving member, and the first shaping block is provided with a first shaping protrusion, the end surface of the first shaping protrusion facing the support assembly is a first shaping surface, and the lower end edge of the first shaping protrusion protrudes outward from the first shaping surface to form a first protrusion; the first shaping block driving member is used to drive the first shaping block to move toward the support assembly, so as to drive the first shaping surface to press the first bus bar onto the first supporting surface, and drive the first protrusion to abut against the first bus bar. the root of the second shaping assembly; the second shaping block driving member includes a second shaping block and a second shaping block, wherein the second shaping block driving member is installed on the mounting bracket, the second shaping block is connected to the driving end of the second shaping block driving member, and the second shaping block is provided with a second shaping protrusion, the end surface of the second shaping protrusion facing the supporting assembly is a second shaping surface, and the lower end edge of the second shaping protrusion protrudes outward from the second shaping surface to form a second protrusion; the second shaping block driving member is used to drive the second shaping block to move toward the supporting assembly, so as to drive the second shaping surface to press the second bus bar onto the second supporting surface, and drive the second protrusion to abut against the root of the second bus bar.

[0016] Provided are a first shaping component and a second shaping component with simple structure and easy implementation, which can ensure the straightening effect of the busbar.

[0017] In some embodiments, the busbar shaping mechanism further includes a transverse movement module, and the lifting module is connected to the driving end of the transverse movement module; a first shovel is also provided on the first shaping block, and the first shovel and the first shaping protrusion are arranged side by side along the first horizontal direction; a second shovel is also provided on the second shaping block, and the second shovel and the second shaping protrusion are arranged side by side along the first horizontal direction, and the second shovel is opposite to the first shovel; the transverse movement module is used to drive the mounting bracket to translate along the first horizontal direction to move the first shovel and the second shovel to above the two busbars; the lifting module drives the first shaping block and the second shaping block to press against the photovoltaic module, and the first shaping block drives The component drives the first shaping block to move toward the support assembly to drive the first shovel blade to be inserted between the first bus bar and the photovoltaic assembly; the second shaping block driving component drives the second shaping block to move toward the support assembly to drive the second shovel blade to be inserted between the second bus bar and the photovoltaic assembly; the lifting module is also used to drive the first shaping block and the second shaping block away from the photovoltaic assembly to drive the first shovel blade and the second shovel blade to scoop the first bus bar and the second bus bar from the photovoltaic assembly respectively; the transverse movement module is also used to drive the mounting bracket to translate along the first horizontal direction after the bus bar is scooped up to move the first shaping protrusion and the second shaping protrusion to above the two bus bars.

[0018] By respectively arranging the first shovel blade and the second shovel blade on the first shaping block and the second shaping block, the first bus bar and the second bus bar can be scooped up from the photovoltaic component, thereby ensuring that the first shaping block and the second shaping block can smoothly press the first bus bar and the second bus bar onto the two opposite support surfaces of the support component.

[0019] In some embodiments, the first supporting surface and the second supporting surface are outwardly convex arcuate supporting surfaces; the first shaping surface and the second shaping surface are inwardly concave arcuate shaping surfaces matching the arcuate supporting surfaces; the shaping ends of the first protrusion and the second protrusion are inwardly concave arcuate surfaces.

[0020] Such a setting enables the first shaping surface and the second shaping surface to more firmly press the first bus and the second bus bar onto the first supporting surface and the second supporting surface, and the first protrusion and the second protrusion can more stably rest against the roots of the first bus bar and the second bus bar, ultimately further improving the shaping effect of the bus bar.

[0021] In some embodiments, the support assembly includes a clamping cylinder, a first support block and a second support block, wherein: the clamping cylinder is mounted on a mounting bracket, and the first support block and the second support block are respectively connected to the first driving end and the second driving end of the clamping cylinder; the inner surface of the first support block and the inner surface of the second support block are both planes, and the inner surface of the first support block is close to the inner surface of the second support block; the outer surface of the first support block includes a first support surface, a first inclined surface and a first avoidance surface connected in sequence, and the first support surface is close to the first driving end of the clamping cylinder; the distance between the first support surface and the inner surface of the first support block is greater than the distance between the first avoidance surface and the inner surface of the first support block; the outer surface of the second support block includes a second support surface, a second inclined surface connected in sequence and a second avoidance surface, and the second supporting surface is close to the second driving end of the clamping cylinder; the distance between the second supporting surface and the inner surface of the second supporting block is greater than the distance between the second avoidance surface and the inner surface of the second supporting block; the clamping cylinder is used to drive the first supporting block and the second supporting block to move relative to each other, so as to realize the switching of the supporting assembly between the avoidance state and the supporting state; when the supporting assembly switches to the avoidance state, the projections of the first avoidance surface and the second avoidance surface on the vertical plane at least partially overlap, and the first supporting surface and the second supporting surface are staggered, wherein the vertical plane is parallel to the inner surface of the first supporting block and the inner surface of the second supporting block; when the supporting assembly switches to the supporting state, the first avoidance surface and the second avoidance surface are staggered, and the projections of the first supporting surface and the second supporting surface on the vertical plane at least partially overlap.

[0022] Before the busbars are reshaped, the clamping cylinder drives the first support block and the second support block to move relative to each other, so that the support assembly switches to the avoidance state. At this time, the overall thickness of the middle part of the support assembly is thinner. In this way, when the lifting module drives the mounting bracket to descend, the thinner middle part of the support assembly can be smoothly inserted between the two busbars, preventing the support assembly from being blocked by the busbars and unable to be inserted between the two busbars due to the distance between the two busbars being too small. After the middle part of the support assembly is inserted between the two busbars, the clamping cylinder drives the first support block and the second support block to move relative to the middle, so that the support assembly switches to the supporting state. At this time, the middle part of the support assembly becomes thicker, so that the two busbars are close to or close to the first support surface and the second support surface of the support assembly, respectively.

[0023] In some embodiments, the support assembly also includes a first limit block and a second limit block, wherein: the first limit block is installed on the first driving end of the clamping cylinder, the first support block is connected to the first limit block, the second limit block is installed on the second driving end of the clamping cylinder, and the second support block is connected to the second limit block; the side of the first limit block opposite to the second limit block is the first front face, and the side of the second limit block opposite to the first limit block is the second front face; when the clamping cylinder drives the first support block and the second support block to move relative to each other to switch the support assembly to the supporting state, the first front face and the second front face respectively adjust the two bus bars simultaneously from both sides of the width direction of the bus bar.

[0024] By providing the first limiting block and the second limiting block, the two bus bars are aligned in the width direction, ensuring that the two bus bars are finally straightened to an upright state.

[0025] In some embodiments, the first protrusion and the second protrusion are rollers.

[0026] The friction of the first and second protrusions on the first and second bus bars is reduced, thereby reducing the risk of wear of the first and second bus bars by the first and second protrusions during the shaping process. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] The existing shaping mechanism has a straightening effect that varies depending on the busbar. For busbars with light wrinkles or no wrinkles, the straightening effect can meet the requirements, but for busbars with severe wrinkles, the straightening effect is poor, and wrinkles still exist after straightening. This may cause the wrinkled part of the busbar to be unable to fully fit with the conductive sheet of the junction box when welding to the junction box, resulting in poor welding.

[0052] In order to solve the above technical problems existing in the existing shaping mechanism, the present invention provides a busbar shaping mechanism for shaping two busbars on a photovoltaic module, where the two busbars are a first busbar and a second busbar.

[0053] like Figures 1-8 As shown, the busbar shaping mechanism provided by the embodiment of the present invention includes a lifting module 1, a mounting bracket 2, a support assembly 3, a first shaping assembly 4 and a second shaping assembly 5, wherein:

[0054] The mounting bracket 2 is connected to the driving end of the lifting module 1 . The support assembly 3 is arranged on the mounting bracket 2 . The two back-to-back sides of the support assembly 3 are respectively a first support surface 321 and a second support surface 331 .

[0055] The first shaping component 4 and the second shaping component 5 are arranged on the mounting bracket 2 and are respectively located on the first side and the second side of the support component 3, wherein the first shaping component 4 is provided with a first shaping surface 44 facing the first supporting surface 321, and a first protrusion 45 protruding outward from the first shaping surface 44 is provided below the first shaping surface 44; the second shaping component 5 is provided with a second shaping surface 54 facing the second supporting surface 331, the second shaping surface 54 is opposite to the first shaping surface 44, and a second protrusion 55 protruding outward from the second shaping surface 54 is provided below the second shaping surface 54; the first protrusion 45 and the second protrusion 55 are lower than the support component 3.

[0056] The lifting module 1 is used to drive the mounting bracket 2 to descend, so that the support assembly 3 is inserted between the two bus bars, and the first shaping assembly 4 and the second shaping assembly 5 are pressed against the photovoltaic assembly; the first shaping assembly 4 is used to press the first bus bar 100 onto the first supporting surface 321 through the first shaping surface 44, and the first protrusion 45 abuts against the root of the first bus bar 100; the second shaping assembly 5 is used to press the second bus bar 200 onto the second supporting surface 331 through the second shaping surface 54, and the second protrusion 55 abuts against the root of the second bus bar 200.

[0057] The lifting module 1 is also used to drive the mounting bracket 2 to rise, so as to drive the supporting assembly 3, the first shaping assembly 4 and the second shaping assembly 5 to straighten the two bus bars upwards.

[0058] The working process of the busbar shaping mechanism of the embodiment of the present invention is as follows:

[0059] The lifting module 1 drives the mounting bracket 2 to descend toward the two bus bars, so that the support assembly 3 is inserted between the first bus bar 100 and the second bus bar 200 , and the first shaping assembly 4 and the second shaping assembly 5 are pressed against the photovoltaic assembly 300 .

[0060] Next, the first shaping component 4 moves from the first side toward the support component 3. The first shaping component 4 presses the first busbar 100 onto the first support surface 321 of the support component 3 via the first shaping surface 44, with the first protrusion 45 abutting the base of the first busbar 100. Simultaneously, the second shaping component 5 moves from the second side toward the support component 3. The second shaping component 5 presses the second busbar 200 onto the second support surface 331 of the support component 3 via the second shaping surface 54, with the second protrusion 55 abutting the base of the second busbar 200.

[0061] Then, the lifting module 1 drives the mounting bracket 2 to rise away from the two bus bars, and the first shaping component 4, the second shaping component 5 and the support component 3 cooperate to straighten the two bus bars upward. At the same time, the first protrusion 45 and the second protrusion 55 implement secondary straightening of the first bus bar 100 and the second bus bar 200. During the secondary straightening process, the first protrusion 45 and the second protrusion 55 can respectively open the wrinkles on the first bus bar 200 and the second bus bar 200, thereby ensuring the straightening effect of the first bus bar 100 and the second bus bar 200.

[0062] Optionally, in order to reduce the friction of the first protrusion and the second protrusion on the first bus bar and the second bus bar, and reduce the risk of wear of the first protrusion and the second protrusion on the first bus bar and the second bus bar during the shaping process, the first protrusion and the second protrusion are both designed as rollers.

[0063] Continue to refer Figure 1 As shown, the busbar shaping mechanism of the embodiment of the present invention further includes a first mounting plate 6 and an elastic connector 7, wherein: the first mounting plate 6 is mounted on the driving end of the lifting module 1, the upper end of the elastic connector 7 is connected to the first mounting plate 6, and the mounting bracket 2 is connected to the lower end of the elastic connector 7. When the lifting module 1 drives the first mounting plate 2 to descend, and the mounting bracket 2 is synchronously lowered to the target position, the support assembly 3 is inserted between the first busbar and the second busbar, the elastic connector 7 is compressed, and the first shaping assembly 4 and the second shaping assembly 5 are elastically pressed against the photovoltaic module.

[0064] The first shaping component 4 and the second shaping component 5 are elastically pressed against the photovoltaic component. On the one hand, this can reduce the risk of pressure damage to the photovoltaic component by the first shaping component 4 and the second shaping component 5. On the other hand, it can ensure that the first shaping component 4 and the second shaping component 5 can slide closely against the photovoltaic component toward the support component 3, and finally press the corresponding bus bar onto the support component 3.

[0065] Optionally, the elastic connecting member 7 includes a guide rod and a spring, the upper end of the guide rod passes through the first mounting plate 6 and is slidingly connected to the first mounting plate 6, the lower end of the guide rod is connected to the mounting bracket 2, and the spring is mounted on the guide rod and its two ends are respectively in contact with the first mounting plate 6 and the mounting bracket 2.

[0066] Optionally, the busbar shaping mechanism in the embodiment of the present invention further includes a photoelectric sensor 8 and a sensor sheet 9, wherein the photoelectric sensor 8 is mounted on the first mounting plate 6, and the sensor sheet 9 is mounted on the mounting bracket 2. During the process of the lifting module 1 driving the mounting bracket 2 to descend, the elastic connector 7 is compressed. When the elastic connector 7 is compressed to a predetermined compression amount, the sensor sheet 9 triggers the photoelectric sensor 8, and the photoelectric sensor 11 generates a stop trigger signal, and the lifting module 1 stops driving the first mounting plate 6. In this way, it can be ensured that the first shaping component 4 and the second shaping component 5 are elastically pressed against the photovoltaic component with a predetermined force, preventing the first shaping component 4 and the second shaping component 5 from exerting excessive pressure on the photovoltaic component and damaging the photovoltaic component.

[0067] Of course, the installation positions of the photoelectric sensor 8 and the sensing piece 9 may also be exchanged, that is, the photoelectric sensor 8 is installed on the installation bracket 2 , and the sensing piece 9 is installed on the first installation plate 6 .

[0068] like Figure 1 and Figure 2 As shown, to facilitate the installation layout of the first shaping assembly 4, the second shaping assembly 5, and the support assembly 3, the mounting bracket 2 optionally includes a second mounting plate 21, a first vertical plate 22, and a second vertical plate 23, wherein the second mounting plate 21 is connected to the driving end of the lifting module 1. The upper ends of the first vertical plate 22 and the second vertical plate 23 are both fixedly connected to the second mounting plate 21, the first shaping assembly 4 is mounted on the lower end of the first vertical plate 22, the second shaping assembly 5 is mounted on the lower end of the second vertical plate 23, and the support assembly 3 is mounted on the second mounting plate 21 and located between the first vertical plate 22 and the second vertical plate 23.

[0069] Optional, such as Figure 2 and Figure 3 As shown, the first shaping assembly 4 includes a first shaping block driver 41 and a first shaping block 42. The first shaping block driver 41 is mounted on the mounting bracket 2. The first shaping block 42 is connected to the driving end of the first shaping block driver 41. The first shaping block 42 is provided with a first shaping protrusion 43. The end surface of the first shaping protrusion 43 facing the support assembly 3 is a first shaping surface 44. The lower edge of the first shaping protrusion 43 protrudes outward from the first shaping surface to form a first protrusion 45. The first shaping block driver 41 is used to drive the first shaping block 42 toward the support assembly 3, thereby driving the first shaping surface 44 to press the first busbar 100 against the first support surface 321 of the support assembly 3 and driving the first protrusion 45 to abut the base of the first busbar 100.

[0070] like Figure 2 and Figure 4As shown, the second shaping assembly 5 includes a second shaping block driver 51 and a second shaping block 52. The second shaping block driver 51 is mounted on the mounting bracket 2. The second shaping block 52 is connected to the driving end of the second shaping block driver 51. The second shaping block 52 is provided with a second shaping protrusion 53. The end surface of the second shaping protrusion 53 facing the support assembly 3 is a second shaping surface 54. The lower edge of the second shaping protrusion 53 protrudes outward from the second shaping surface 54 to form a second protrusion 55. The second shaping block driver 51 is used to drive the second shaping block 52 toward the support assembly 3, thereby driving the second shaping surface 54 to press the second busbar 200 against the second support surface 331 of the support assembly 3 and driving the second protrusion 55 to abut the base of the second busbar 200.

[0071] After the first shaping blocks 42 and the second shaping blocks 52 press the first and second busbars onto the first and second supporting surfaces 321 and 331 of the support assembly 3, the lifting module 1 drives the mounting bracket 2 upward away from the two busbars. The first shaping surface 44 of the first shaping assembly 4 and the second shaping surface 54 of the second shaping assembly 5 cooperate with the first and second supporting surfaces 321 and 331 of the support assembly to straighten the two busbars upward. Simultaneously, the first and second protrusions 45 and 55 perform a secondary straightening of the first and second busbars.

[0072] Normally, when the high-temperature cloth is torn off, the two bus bars will be lifted up so that the bus bars are tilted. At this time, the bus bar shaping mechanism in the above embodiment is used. The first shaping protrusion 43 and the second shaping protrusion 53 can push up the two bus bars and press them onto the first support surface 321 and the second support surface 331 respectively when moving toward the bus bar.

[0073] However, there are some special cases where the busbar may not be fully lifted after the high-temperature cloth is removed, that is, the busbar may still be attached to the photovoltaic module. In this case, the first shaping protrusion 43 and the second shaping protrusion 53 will not be able to smoothly push up the busbar when moving towards the busbar, and ultimately the busbar cannot be straightened.

[0074] In order to solve this problem, optionally, the busbar shaping mechanism in the embodiment of the present invention further includes a transverse module, and the lifting module 1 is connected to the driving end of the transverse module. Figure 3 and Figure 4 As shown, the first shaping block 42 is further provided with a first scooping blade 46, which is arranged side by side with the first shaping protrusion 43 along the first horizontal direction (the X-axis direction in the figure). The second shaping block 52 is further provided with a second scooping blade 56, which is arranged side by side with the second shaping protrusion 53 along the first horizontal direction (the X-axis direction in the figure), and the second scooping blade 56 is opposite to the first scooping blade 46.

[0075] The working process of the busbar shaping mechanism is as follows:

[0076] The transverse movement module drives the mounting bracket 2 to translate along the first horizontal direction to the first position, so that the first scoop blade 46 and the second scoop blade 56 move to above the two bus bars.

[0077] Lifting module 1 drives mounting bracket 2 downward, causing first shaping block 42 and second shaping block 52 to descend and eventually rest against the PV module. Next, first shaping block driver 41 drives first shaping block 42 toward support assembly 3, inserting first scoop 46 between the first busbar and the PV module. Simultaneously, second shaping block driver 51 drives second shaping block 52 toward support assembly 3, inserting second scoop 56 between the second busbar and the PV module.

[0078] The lifting module 1 then drives the first shaping block 42 and the second shaping block 52 to rise away from the photovoltaic assembly, driving the first shovel blade 46 and the second shovel blade 56 to scoop up the first bus bar and the second bus bar from the photovoltaic assembly respectively.

[0079] Next, the transverse movement module drives the mounting bracket 2 to translate along the first horizontal direction to the second position, so that the first shaping protrusion 43 and the second shaping protrusion 53 move to above the two bus bars.

[0080] The lifting module 1 drives the mounting bracket 2 downward, inserting the support assembly 3 between the two scooped busbars and pressing the first shaping block 42 and the second shaping block 52 against the photovoltaic assembly. Next, the first shaping block driver 41 drives the first shaping block 42 toward the support assembly 3, driving the first shaping protrusion 43 to press the first busbar against the first supporting surface of the support assembly 3, with the first protrusion 45 resting against the root of the first busbar. Simultaneously, the second shaping block driver 51 drives the second shaping block 52 toward the support assembly 3, driving the second shaping protrusion 53 to press the second busbar against the second supporting surface of the support assembly 3, with the second protrusion 55 resting against the root of the second busbar.

[0081] Then, the lifting module 1 drives the mounting bracket 2 to rise away from the two bus bars, and the first shaping block 42, the second shaping block 52 and the support assembly 3 cooperate to straighten the two bus bars upward. At the same time, the first protrusion 45 and the second protrusion 55 implement secondary straightening of the first bus bar and the second bus bar.

[0082] It can be seen that by respectively arranging the first shovel blade 46 and the second shovel blade 56 on the first shaping block 42 and the second shaping block 52, the first shaping block 42 and the second shaping block 52 can scoop up the first bus bar and the second bus bar from the photovoltaic component, thereby ensuring that the first shaping block 42 and the second shaping block 52 can smoothly press the first bus bar and the second bus bar onto the first support surface and the second support surface of the support component 3.

[0083] Optional, such as Figure 3 、 4 As shown in Figures 7 and 8, the first supporting surface 321 and the second supporting surface 331 are outwardly convex arc-shaped supporting surfaces; the first shaping surface 44 and the second shaping surface 54 are inwardly concave arc-shaped shaping surfaces matching the arc-shaped supporting surfaces; the shaping ends of the first protrusion 45 and the second protrusion 55 (i.e., the front end surface close to the busbar) are inwardly concave arc-shaped surfaces.

[0084] This arrangement ensures that the first shaping surface 44 and the second shaping surface 54 can more firmly press the first busbar and the second busbar against the first support surface 321 and the second support surface 331 of the support assembly 3. The first protrusion 45 and the second protrusion 55 can stably abut the roots of the first busbar and the second busbar, ultimately improving the shaping effect of the busbars.

[0085] like Figures 5 to 8 As shown, the support assembly 3 includes a clamping cylinder 31, a first support block 32 and a second support block 33, wherein: the clamping cylinder 31 is installed on the mounting bracket 2, and the first support block 32 and the second support block 33 are respectively connected to the first driving end and the second driving end of the clamping cylinder 31.

[0086] The inner surface of the first support block 32 and the inner surface of the second support block 33 are both planes, and the inner surface of the first support block 32 is close to the inner surface of the second support block 33 .

[0087] The outer surface of the first support block 32 includes a first support surface 321, a first inclined surface 322, and a first relief surface 323, which are connected in sequence. The first support surface 321 is located near the first driving end of the clamping cylinder 31. The distance between the first support surface 321 and the inner surface of the first support block 32 is greater than the distance between the first relief surface 323 and the inner surface of the first support block 32. In other words, the thickness of the first support block 32 at the location of the first support surface 321 is greater than the thickness at the location of the first relief surface 323.

[0088] The outer surface of the second support block 33 includes a second support surface 331, a second inclined surface 332, and a second relief surface 333, which are connected in sequence. The second support surface 331 is located near the second driving end of the clamping cylinder 31. The distance between the second support surface 331 and the inner surface of the second support block 33 is greater than the distance between the second relief surface and the inner surface of the second support block 33. In other words, the thickness of the second support block 33 at the location of the second support surface 331 is greater than the thickness at the location of the second relief surface 333.

[0089] The clamping cylinder 31 is used to drive the first support block 32 and the second support block 33 to move relative to each other, so as to switch the support assembly 3 between the avoidance state and the support state. Figure 5 and Figure 6 As shown, when the support assembly 3 switches to the avoidance state, the projections of the first avoidance surface 323 and the second avoidance surface 333 on the vertical plane at least partially overlap, and the first support surface 321 and the second support surface 331 are staggered, wherein the vertical plane is parallel to the inner surface of the first support block 32 and the inner surface of the second support block 33.

[0090] like Figure 7 and Figure 8 As shown, when the support assembly 3 switches to the supporting state, the first avoidance surface 323 and the second avoidance surface 333 are staggered, and the projections of the first support surface 321 and the second support surface 331 on the vertical plane at least partially overlap.

[0091] Before performing busbar shaping, Figures 5 to 6 As shown, the clamping cylinder 31 drives the first support block 32 and the second support block 33 to move relative to each other, so that the support assembly 3 switches to the avoidance state. At this time, the overall thickness of the middle part of the support assembly 3 is the thinner first thickness.

[0092] In this way, when the lifting module 1 drives the mounting bracket 2 to descend, the thinner middle portion of the support component 3 can be smoothly inserted between the first bus bar 100 and the second bus bar 200, preventing the first bus bar 100 and the second bus bar 200 from being too small in distance therebetween due to deformation or other reasons, and the support component 3 cannot be smoothly inserted between the first bus bar and the second bus bar.

[0093] When the lifting module 1 is driven to its position and the middle portion of the support assembly 3 is fully inserted into the first bus bar 100 and the second bus bar 200, as shown in FIG. Figures 7 and 8As shown, the clamping cylinder 31 drives the first support block 32 and the second support block 33 to move toward the center relative to each other, causing the support assembly 3 to switch to the supporting state. At this time, the overall thickness of the middle portion of the support assembly 3 is the thicker second thickness, so that the first support surface 321 and the second support surface 331 of the support assembly 3 can contact the first bus bar 100 and the second bus bar 200, respectively, to provide support for the first bus bar 100 and the second bus bar 200.

[0094] like Figure 5 and Figure 8 As shown, the support assembly 3 optionally further includes a first limit block 34 and a second limit block 35, wherein: the first limit block 34 is mounted on the first driving end of the clamping cylinder 31, and the first support block 32 is connected to the first limit block 34. The second limit block 35 is mounted on the second driving end of the clamping cylinder 31, and the second support block 33 is connected to the second limit block 35. The side of the first limit block 34 opposite the second limit block 35 is the first front face, and the side of the second limit block 35 opposite the first limit block 34 is the second front face.

[0095] The clamping cylinder 31 drives the first support block 32 and the second support block 33 to move relative to each other. In the process of switching the support assembly 3 to the supporting state, the first front face and the second front face respectively straighten the two bus bars from both sides of the width direction of the bus bar, thereby straightening the bus bar that is tilted in the width direction.

[0096] After the first limit block 34 and the second limit block 35 straighten the busbars, the first shaping block driving member 41 can drive the first shaping protrusion 43 to move toward the first busbar 100, so that the first shaping surface 44 presses the first busbar 100 against the first supporting surface 321, and the first protrusion 45 abuts the root of the first busbar 100; the second shaping block driving member 51 can drive the second shaping protrusion 53 to move toward the second busbar 200, so that the second shaping surface 54 presses the second busbar 200 against the second supporting surface 331, and the second protrusion 55 abuts the root of the second busbar 200; then, the lifting module 1 drives the mounting bracket 2 to rise away from the two busbars, and the first limit block 34 and the second limit block 35 limit the first busbar 100 and the second busbar 200 in the width direction during the rising process to prevent the busbars from skewing during the straightening process.

[0097] The present invention has been described above in sufficient detail with certain particularities. Those skilled in the art will appreciate that the descriptions in the embodiments are merely illustrative, and that all modifications that do not depart from the true spirit and scope of the invention are intended to be within the scope of protection of the present invention.
