Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, specifically relating to a straightening and punching mechanism. Background Technology

[0002] Currently, the automated production of backsheet modules in the photovoltaic industry is still in its nascent stage of development, making automated production particularly important. The copper foil backsheet punching process in backsheet module production is also constantly evolving. With continuous innovation in battery technology and increasingly mature breakthroughs in battery module manufacturing, backsheet punching is a crucial step in the backsheet module process.

[0003] Currently, most punching equipment on the market uses mechanical positioning (suitable for materials with good rigidity) or a lower platform for overall straightening and a fixed-position punching cutter (suitable for smaller materials, such as those less than 0.8cm in length and width). With the development of photovoltaic module technology, copper foil backsheet materials are becoming increasingly larger, currently reaching 2.6*1.3m. For punching large-area materials, where the backsheet plane requires transport and planar adsorption, straightening via a lower platform becomes more complex. Therefore, existing punching mechanisms are not suitable for punching large-area materials with low rigidity. Utility Model Content

[0008] The X-axis linear module is used to drive the cutter mounting bracket to move along the length direction of the cutter mounting bracket, and the Y-axis linear module is used to drive the cutter mounting bracket to move along a direction perpendicular to the length direction of the cutter mounting bracket or to adjust the angle of the cutter mounting bracket relative to the correction module.

[0009] As a further improvement of this utility model, both the X-axis linear module and the Y-axis linear module include a drive unit, a first guide rail, a first slider, a second guide rail, and a bearing;

The first slider is slidably connected to the first guide rail. The driving unit is used to drive the first slider to slide along the first guide rail.

[0011] The second guide rail is located above the first slider, and the length direction of the second guide rail is perpendicular to the length direction of the first guide rail. The second guide rail can move along the length direction of the second guide rail.

[0012] The end mounting plate is rotatably connected to the X-axis linear module and the Y-axis linear module via corresponding bearings.

[0013] As a further improvement of this utility model, the driving unit includes a driving component and a lead screw connected to the power output end of the driving component, and the lead screw is fixedly connected to the first slider through an adapter plate.

[0014] As a further improvement of this utility model, the second guide rail is slidably connected to the first slider, the second guide rail is provided with a bearing mounting plate, the bearing mounting plate is provided with a bearing, and the end mounting plate is mounted on the bearing.

[0015] As a further improvement of this utility model, a second slider is installed on the adapter plate or the first slider, and the second guide rail is slidably connected to the second slider.

[0016] As a further improvement of this utility model, the second guide rail is provided with a bearing mounting plate, the bearing mounting plate is provided with a bearing, and the end mounting plate is mounted on the bearing.

[0017] As a further improvement of this utility model, the bearing is disposed between the adapter plate and the second slider, or the bearing is disposed between the first slider and the second slider, and the end mounting plate is mounted on the second guide rail.

[0018] As a further improvement of this utility model, the cutter mounting bracket includes an upper mounting bracket and a lower mounting bracket, and the cutting unit includes an upper clamping block mounted on the upper mounting bracket, a lower clamping block mounted on the lower mounting bracket, and a cutting part; the upper clamping block is located above the material to be cut, and the lower clamping block is located below the material to be cut, and both the upper and lower clamping blocks are provided with through holes for the cutting part to pass through; the cutting part can pass through the through holes to punch the material to be cut when the upper and lower clamping blocks clamp the material to be cut.

[0022] In summary, the technical solutions conceived by this utility model have the following beneficial effects compared with the prior art:

The X-axis linear modules at both ends of the cutter mounting frame drive the cutter mounting frame to move along its length direction. The Y-axis linear modules at both ends of the cutter mounting frame drive the cutter mounting frame to move in a direction perpendicular to its length direction or adjust the angle of the cutter mounting frame relative to the corrective module, thereby adjusting the position of the cutting unit and correcting the punching position of the back plate, ensuring the positional accuracy of the punching hole. It is suitable for punching large-area materials with low rigidity. Attached Figure Description

[0037] As a preferred embodiment of this utility model, such as Figures 1 to 5 As shown, the device includes a cutter mounting frame 1 and a straightening module 2 disposed at both ends of the cutter mounting frame 1 along its length direction. The straightening module 2 includes a base mounting plate 21, an X-axis linear module 23 and a Y-axis linear module 22 disposed on the base mounting plate 21, and an end mounting plate 24 rotatably connected to both the X-axis linear module 23 and the Y-axis linear module 22. Along the length direction of the cutter mounting frame 1, both ends of the cutter mounting frame 1 are fixedly mounted on the corresponding end mounting plates 24, and at least one cutting unit 3 is mounted on the cutter mounting frame 1.

[0038] The X-axis linear module 23 is used to drive the cutter mounting frame 1 to move along the length direction of the cutter mounting frame 1, and the Y-axis linear module 22 is used to drive the cutter mounting frame 1 to move along a direction perpendicular to the length direction of the cutter mounting frame 1 or to adjust the angle of the cutter mounting frame 1 relative to the correction module 2.

[0039] The X-axis linear module 23 and the Y-axis linear module 22 have the same structure and are installed perpendicular to each other. In this embodiment, the Y-axis linear module 22 is used as an example to describe its specific structure. Figure 3 As shown, the Y-axis linear module 22 includes a drive unit, a first guide rail 223, a first slider 224, a second guide rail 225, and a bearing 227.

[0040] The drive unit and the first guide rail 223 are both mounted on the base mounting plate 21. The first guide rail 223 is set along the drive direction of the drive unit. The first slider 224 is slidably connected to the first guide rail 223. The drive unit is used to drive the first slider 224 along the first guide rail 223. The second guide rail 225 is located above the first slider 224. The length direction of the second guide rail 225 is perpendicular to the length direction of the first guide rail 223. The second guide rail 225 can move along the length direction of the second guide rail 225. The end mounting plate 24 is rotatably connected to the X-axis linear module 23 and the Y-axis linear module 22 through corresponding bearings 227.

[0041] Preferably, the drive unit includes a drive component 228 (such as a cylinder) and a lead screw 221 connected to the power output end of the drive component 228, and the lead screw 221 is fixedly connected to the first slider 224 via an adapter plate 222. Under the action of the drive component 228, the rotation of the lead screw 221 drives the adapter plate 222 and the first slider 224 to move linearly along the first guide rail 223.

[0042] In the first embodiment, the second guide rail 225 is slidably connected to the first slider 224, that is, the first guide rail 223 and the second guide rail 225 share a slider; the second guide rail 225 is provided with a bearing mounting plate 226, the bearing mounting plate 226 is provided with a bearing 227, and the end mounting plate 24 is mounted on the bearing 227.

[0043] In the second embodiment, a second slider (not shown in the figure) is mounted on the adapter plate 222 or the first slider 224, and the second guide rail 225 is slidably connected to the second slider. In this embodiment, the bearing 227 can be disposed between the bearing mounting plate 226 and the end mounting plate 24, that is, the second guide rail 225 is provided with the bearing mounting plate 226, the bearing mounting plate 226 is provided with the bearing 227, and the end mounting plate 24 is mounted on the bearing 227; the bearing 227 can also be disposed between the adapter plate 222 and the second slider or between the first slider 224 and the second slider, in which case the end mounting plate 24 is directly mounted on the second guide rail 225.

[0044] Preferably, in the above embodiments, the bearing 227 is a tapered roller bearing, including an inner ring and an outer ring disposed outside the inner ring, the inner ring being rotatable relative to the outer ring. Specifically, in the first embodiment, the inner ring is fixedly connected to the end mounting plate 24, and the outer ring is fixedly mounted on the bearing mounting plate 226. In the second embodiment, when the bearing 227 is disposed between the end mounting plate 24 and the bearing mounting plate 226, the arrangement of the inner ring and the outer ring is the same as in the previous embodiments; when the bearing 227 is disposed between the second slider and the first slider, the inner ring can be fixedly connected to the second slider, and the outer ring can be fixedly connected to the first slider; when the bearing 227 is disposed between the second slider and the adapter plate, the inner ring can be fixedly connected to the second slider, and the outer ring can be fixedly connected to the adapter plate.

[0045] It is understood that in the Y-axis linear module 22, the lead screw 221 and the first guide rail 223 are both set along the Y-axis direction, and the second guide rail 225 is set along the X-axis direction. For the X-axis linear module 23, its lead screw and first guide rail are both set along the X-axis direction, and the second guide rail is set along the Y-axis direction. The specific structure of the X-axis linear module 23 is the same as that of the Y-axis linear module 22, and will not be described again here. Here, the Y-axis direction refers to the conveying direction of the material to be punched, and the X-axis direction refers to the length direction of the cutter mounting bracket 1. The X-axis direction and the Y-axis direction are perpendicular to each other.

[0046] This application has a set of correction modules 2 at each end of the length direction of the cutter mounting frame 1, which work together to achieve the overall correction of the cutter mounting frame 1. Since the cutter mounting frame 1 involves not only linear movement and adjustment along the X and Y axes when the left and right ends are linked, but also angular adjustment in the horizontal direction, the cutter mounting frame 1 will experience relative to the correction modules 2. This application uses a second guide rail 225 perpendicular to the first guide rail 223 and a bearing 227 to ensure that the cutter mounting frame 1 has no dead points in its linear movement and horizontal rotation adjustment in the X and Y axes.

[0047] The process of adjusting the straightening and blanking mechanism of this utility model along the Y-axis, X-axis, and horizontal rotation is as follows:

[0048] The visual module (such as a camera) performs visual positioning detection on the material to be punched that moves to the bottom of the punching mechanism, and transmits the result to the control system. The two end correction modules 2 receive the control system's instructions and cooperate to complete the accurate movement of the cutter mounting frame 1, thereby adjusting the cutting unit 3 on the cutter mounting frame 1 to the position on the material to be punched that requires punching.

[0049] When the entire blanking mechanism needs to be adjusted along the Y-axis, the Y-axis linear modules 22 at both ends of the cutter mounting bracket 1 move synchronously. Specifically, the drive unit 228 of the Y-axis linear module 22 drives the first slider 224 to slide along the first guide rail 223, causing the blanking mechanism to move along the Y-axis. At the same time, the movement causes the second guide rail of the X-axis linear module 23 to slide relative to the first or second slider of the X-axis linear module 23 in the Y-axis direction.

[0050] When the entire blanking mechanism needs to be adjusted along the X-axis, the X-axis linear modules 23 at both ends of the cutter mounting bracket 1 move synchronously. Specifically, the drive unit of the X-axis linear module 23 drives the first slider of the X-axis module to slide along the first guide rail, so that the blanking mechanism moves along the X-axis. At the same time, the movement causes the second guide rail 225 of the Y-axis linear module 22 to slide relative to the first or second slider of the Y-axis linear module 22 in the X-axis direction.

[0051] When the entire punching mechanism needs to be horizontally rotated for adjustment:

[0052] On one hand, the drive component 228 in the Y-axis linear module 22 at one end of the cutter mounting frame 1 can drive the first slider in the Y-axis linear module 22 to slide along the first guide rail, and drive the second guide rail of the X-axis linear module 23 to slide relative to the first or second slider of the X-axis linear module 23 in the Y-axis direction. During this process, the inner rings of the bearings in the X-axis linear modules 23 and the bearings 227 in the Y-axis linear modules 22 at both ends rotate relative to their outer rings, so that the end mounting plate 24 at that end can move along the Y-axis direction, thereby enabling one end of the cutter mounting frame 1 to move along the Y-axis, thereby realizing the overall rotational adjustment of the punching mechanism in the horizontal direction, so that the cutting unit 3 on the cutter mounting frame 1 corresponds to the preset punching position on the material to be punched.

[0053] On the other hand, the Y-axis linear modules 22 at both ends of the cutter mounting frame 1 can also be moved in the opposite direction along the Y-axis. Similarly, the second guide rails of the X-axis linear modules 23 at both ends can slide along the corresponding first or second slider in the Y-axis direction. At the same time, the inner rings of the bearings 227 of the X-axis linear modules 23 and Y-axis linear modules 22 at both ends rotate in opposite directions relative to the outer rings, thereby causing the two ends of the cutter mounting frame 1 to rotate in opposite directions, adjusting the angle of the cutter mounting frame 1 in the horizontal direction, so that the cutting unit 3 on the cutter mounting frame 1 corresponds to the preset cutting position on the material to be cut.

[0054] Furthermore, combined Figure 1 , Figure 4 and Figure 5 As shown, the straightening and punching mechanism 100 of this embodiment is mounted on the frame 200. The cutter mounting frame 1 includes an upper mounting frame 11 and a lower mounting frame 12, which are integral structures, ensuring their relative positions remain unchanged during the straightening process while maintaining overall movement. The cutting unit 3 includes an upper clamping block 38 mounted on the upper mounting frame 11, a lower clamping block 37 mounted on the lower mounting frame 12, and a cutting part 39. The upper clamping block 38 is located above the material to be punched 300, and the lower clamping block 37 is located below the material to be punched 300. Both the upper and lower clamping blocks 38 and 37 have through holes for the cutting part 39 to pass through. The cutting part 39 can punch the material to be punched 300 by passing through the through holes when the upper and lower clamping blocks 38 and 37 clamp it.

[0055] Preferably, the cutting unit 3 further includes a drive mounting base 31, a punching drive component 32, and a connecting plate. The punching drive component 32 is fixedly mounted on the drive mounting base 31, and the power output end of the punching drive component 32 is connected to the connecting plate 33. The cutting part 39 is mounted on the bottom of the connecting plate. A guide component 33 is provided between the drive mounting base 31 and the connecting plate to guide the upper clamping block 38 during its up-and-down movement. The upper clamping block 38 is located below the connecting plate, and the upper clamping block 38 and the connecting plate are connected by a spring 34 to provide pre-clamping force when the upper clamping block 38 presses the material to be punched onto the lower clamping block 37.

[0056] Preferably, an air blowing unit 35 and a waste material channel 36 are provided below the lower clamping block 37. The waste material channel 36 communicates with the through hole opened in the lower clamping block 37. The air blowing unit 35 is used to convey the waste material generated during punching to the waste material channel 36, preventing the waste material from adhering to the cutting part 39, and allowing the waste material to smoothly enter the waste material channel 36 for collection. Specifically, the gas blown by the air blowing unit 35 acts on the through hole of the lower clamping block 37, so that the waste material generated during punching can fall into the waste material channel 36 under the action of the gas blown by the air blowing unit 35.

[0057] The punching process using the cutting unit 3 in this embodiment is as follows:

[0058] The punching drive 32 drives the upper clamping block 38 downward until the front side of the material to be punched is in contact with the upper clamping block 38 and the back side of the material to be punched is in contact with the lower clamping block 37. The punching drive 32 continues to drive the upper clamping block 38 downward, causing the spring 34 to be partially compressed to provide pre-clamping force, so that the material to be punched 300 is pressed between the upper clamping block 38 and the lower clamping block 37. Then, the punching drive 32 is controlled to continue to drive the upper clamping block 38 downward, the spring 34 is further compressed, and the cutting part 39 passes through the through hole on the upper clamping block 38 and through the material to be punched 300 and inserts into the through hole on the lower clamping block 37, thereby forming a through punch in the material to be punched 300. During the up and down movement of the upper clamping block 38 and the cutting part 39, they are guided by the guide member 33. The waste generated by cutting is removed and collected along the waste channel 36 under the action of the air blowing unit 35.

[0059] Preferably, in order to accommodate punching of different numbers and relative positions, the punching mechanism of this utility model has three sets of cutting units 3 installed on the cutter mounting frame 1, and the relative installation position of each cutting unit 3 can be adjusted according to the actual situation.

[0060] This utility model's straightening and blanking mechanism, through a linear module combination, can achieve three degrees of freedom of straightening action, ensuring the positional accuracy of the blanking hole. This utility model can keep the lower platform transporting the material to be blanked fixed, and straightening is achieved by adjusting the blanking mechanism above the material. It is particularly suitable for blanking large-area materials with low rigidity (such as those exceeding 1m in both length and width). While the blanking mechanism performs its straightening function above the material to be blanked, its external structure not only saves cost and space but also facilitates maintenance. The cutting unit has air blowing and spring preload functions, ensuring smooth and accurate blanking while also facilitating overall adjustment.

[0061] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
