Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing technology, and in particular to a high-temperature cloth tearing device, a busbar shaping and testing device, and an assembly line. Background Technology

[0002] Before the lamination process in photovoltaic manufacturing, high-temperature adhesive tape needs to be applied to the surface of the encapsulation material layer to prevent the adhesive from overflowing during lamination. During lamination, the busbars adhere to the solar cell laminate on both sides, ensuring that the high-temperature adhesive tape and busbars are tightly bonded to the surface of the laminated solar cell laminate. However, during subsequent installation with the junction box, the high-temperature adhesive tape needs to be removed from the surface of the solar cell laminate, and the busbars need to be rotated to a position approximately vertical to the surface of the solar cell laminate. After lamination, the high-temperature tape also needs to be removed, and the busbars, which were bent and attached to the high-temperature tape during lamination, need to be rotated upwards and reshaped to fit the wire holes in the junction box.

[0003] Currently, most high-temperature cloth removal is done manually. There is no specialized equipment or mechanism that can simultaneously heat the busbars, remove the high-temperature cloth, shape the busbars, and perform fully automated visual inspection. Such equipment or mechanisms have not been applied in the photovoltaic module production line. The manual removal of the high-temperature cloth, shaping of the busbars, and visual inspection is still inefficient, time-consuming, and may result in missed removal of the high-temperature cloth or inconsistent shaping of the busbars, leading to high labor and rework costs. Summary of the Invention

The output ends of the third driving component and the second belt assembly are connected.

[0011] In one embodiment of the present invention, the first drive component includes: a first support body disposed along the x-direction on the frame, a first power member disposed on the first support body, and a first belt assembly connected to the output end of the first power member, wherein the second drive component is connected to the output end of the first belt assembly.

[0017] This utility model also discloses an assembly line that uses the above-mentioned high-temperature cloth tearing device and busbar shaping and detection device for dispensing adhesive.

[0018] The technical solution of the present invention has the following advantages compared with the prior art:

[0019] The high-temperature cloth tearing device and busbar shaping and testing device of the present invention consist of a feeding mechanism supported by a frame and a transmission line. The transmission line is used to transport the photovoltaic modules to be processed, allowing the photovoltaic modules to pass through the frame. A three-axis drive mechanism is used to move the lifting mechanism and the high-temperature cloth removal mechanism in three-dimensional space within the frame, so that the lifting mechanism and the high-temperature cloth removal mechanism correspond to the busbar and the high-temperature cloth. The three-axis drive mechanism positions the shovel blades on both sides of the busbar, driving the shovel blades to press down onto the surface of the photovoltaic module. An elastic element stretches the outer side of the shovel blade rotation axis, causing the inner side of the shovel blade to elastically abut against the surface of the photovoltaic module to form prestress. The first clamping cylinder drives the shovel blades to move inward, causing the shovel blades to tear the busbar and the high-temperature cloth from the bottom along the outer edge inward. The high-temperature cloth is scooped up together, driving the entire lifting mechanism upwards a certain distance, keeping the busbar and high-temperature cloth in an inclined state. The first telescopic drive component drives the second clamping cylinder, reference component, and grippers downwards. The second clamping assembly clamps from both sides inwards, using the avoidance groove to avoid the busbar, so that the grippers only contact the high-temperature cloth and not the busbar. The drive grippers clamp the high-temperature cloth onto the reference component. The three-axis drive mechanism tears the high-temperature cloth upwards. Since the busbar is made of tin-plated copper, it has a certain degree of plasticity. By setting reference components of different specifications, the busbar can be lifted and shaped to maintain a vertical position or adapt to the inclined shape of the junction box, realizing integrated and automated tearing of high-temperature cloth, busbar straightening, and detection.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example 1

[0031] Reference Figure 1-8 As shown, the high-temperature fabric tearing device and busbar shaping and detection device of the present invention include:

[0032] The feeding mechanism includes: a frame 1 and a transmission line 7 disposed on the frame 1;

[0033] The lifting mechanism 5 includes: a three-axis drive mechanism 4 disposed on the frame 1, and a lifting assembly connected to the output end of the three-axis drive mechanism 4. The lifting assembly includes: a first clamping cylinder 51, and shovels 52 rotatably connected to the output ends on both sides of the first clamping cylinder 51. An elastic element 54 is connected to the end of the shovels 52.

[0034] The high-temperature fabric taking mechanism 6 includes: a first telescopic drive member 61 disposed at the output end of the three-axis drive mechanism 4, a second clamping cylinder disposed at the output end of the first telescopic drive member 61, grippers 63 respectively connected to the output ends on both sides of the second clamping cylinder, a second telescopic drive member 62 connected to the output end of the first telescopic drive member 61, and a reference member 64 connected to the output end of the second telescopic drive member 62. The grippers 63 are provided with clearance grooves 67 not smaller than the size of the busbar, and the reference member 64 is movably disposed between the grippers 63 on both sides.

[0035] The high-temperature cloth tearing device and busbar shaping and detection device of the present invention consist of a feeding mechanism supported by a frame 1 and a transmission line 7. The transmission line 7 is used to transport the photovoltaic modules to be processed, allowing the photovoltaic modules to pass through the frame 1. A three-axis drive mechanism 4 is used to move the lifting mechanism 5 and the high-temperature cloth removal mechanism in the three-dimensional space within the frame 1, so that the lifting mechanism 5 and the high-temperature cloth removal mechanism correspond to the busbar and the high-temperature cloth. The three-axis drive mechanism 4 positions the scraper blade 52 on both sides of the busbar, driving the scraper blade 52 to press down onto the surface of the photovoltaic module. The elastic element 54 stretches the outer side of the rotation axis of the scraper blade 52, so that the inner side of the scraper blade 52 elastically abuts against the surface of the photovoltaic module to form prestress. The first clamping cylinder 51 drives the scraper blade 52 to move inward, so that the scraper blade 52 moves from the bottom of the busbar and the high-temperature cloth along the outer edge towards... The busbar and high-temperature cloth are lifted together, driving the entire lifting mechanism 5 upward a certain distance, keeping the busbar and high-temperature cloth in an inclined state. The first telescopic drive member 61 drives the second clamping cylinder, the reference member 64 and the gripper 63 downward, using the second clamping assembly to clamp from both sides inward. The avoidance groove 67 avoids the busbar, so that the gripper 63 only contacts the high-temperature cloth and not the busbar. The gripper 63 is driven to clamp the high-temperature cloth onto the reference member 64. The high-temperature cloth is torn upward by the three-axis drive mechanism 4. Since the busbar is made of tin-coated copper, it has a certain plasticity. By setting different specifications of reference members 64, the busbar can be driven to tilt and be shaped to maintain a vertical position or adapt to the inclined shape of the junction box, realizing integrated and automated removal of high-temperature cloth and straightening of busbar.

[0036] In some embodiments, the initial tension of the tension spring is greater than the plastic stress of the busbar. Specifically, the tension torque of the initial tension of the tension spring acting on the upper end of the spade 52 is greater than the compressive torque of the plastic stress of the busbar acting on the lower end of the spade 52. This makes the spade 52 rigid relative to the busbar, facilitating the shaping of the busbar by the spade 52. During the shaping process, the third drive assembly 43 and the first telescopic drive member 61 cooperate. The third drive assembly 43 moves upward to move the gripper 63, and the first telescopic drive member 61 on the output end of the third drive assembly 43 moves downward synchronously. The downward speed and the upward speed of the third drive assembly 43 are synchronized. The reference component 64 is stationary relative to the photovoltaic module, so that the busbar is straightened along the side of the reference component 64 by the scraper blade 52. The busbar can also be shaped by the scraper blade 52 before the high-temperature cloth is removed. The high-temperature part can cover the anti-slip grooves on both sides of the reference component 64 to increase the straightness of the busbar. In some embodiments, the busbar can also be shaped by the gripper 63. After the high-temperature cloth is removed, the three-axis servo component aligns any one of the gripping parts 66 of the gripper 63 with the busbar in the first direction. The busbar can be clamped and attached to the reference component 64 by closing the first gripping cylinder 51, so that the busbar can be shaped by the gripper 63.

[0037] See Figure 5As shown, it also includes a vision inspection mechanism 8, which is disposed at the output end of the three-axis drive mechanism 4. It includes: a first vision component and a second vision component 82 respectively disposed above and to the side of the photovoltaic module under test. The three-axis drive mechanism 4 includes: a first drive component 41 disposed on the frame 1, a second drive component 42 connected to the output end of the first drive component 41, and a third drive component connected to the second drive component 42. The first drive component 41, the second drive component, and the third drive component 43 are used to drive along the x, y, and z axes, respectively. The vision mechanism is used to perform visual inspection of the busbar and the high temperature. When the photovoltaic module stops on the transmission line 7 during the feeding stage, the three-axis drive mechanism 4 drives the first vision component to the top of the high temperature cloth to detect whether the photovoltaic module is attached to the high temperature cloth. If the high temperature cloth is present, the high temperature cloth removal step is performed. If the high temperature cloth is not present, the signal is fed back to the control end of the equipment.

[0038] See also Figure 5 As shown, the visual inspection mechanism 8 is disposed on the second driving component 42. The first visual component includes a first camera 81 disposed on the second driving component 42. The second visual component 82 includes: a bracket disposed on the second driving component 42, a second camera 821 disposed on the bracket, a third telescopic driving member 823 disposed on the bracket, and a prism 822 connected to the output end of the third telescopic driving member 823. The second driving component 42 includes: a first guide rail 411 disposed along the x-direction on the first support body, a second support body 423 slidably connected to the first guide rail 411, a second power member 422 disposed on the second support body 423, and a second belt assembly 421 connected to the output end of the second power member 422. The output ends of the third driving component 43 and the second belt assembly 421 are connected. The transmission line 7 is arranged along the second direction, the first driving component 41 is arranged along the first direction, and the second driving component 42... Arranged along the second direction, the third driving component 43 is arranged along the third direction. The first driving component 41 can drive the second driving component 42 and the vision inspection mechanism 8 to move along the first direction, thereby avoiding the photovoltaic module or moving above the photovoltaic module for inspection. Specifically, the second camera 821 can inspect the side of the busbar by refracting light through the prism 822. The inspection criteria include the spacing and angle of the busbar. The second vision inspection component can drive the prism 822 downward to enable the second camera 821 to inspect busbars at different heights. It can also gradually move the prism 822 to enable the second camera 821 to form a scanning inspection, which ensures the inspection progress while improving the inspection range. The vision inspection is carried out in two stages. The first inspection is carried out by the first vision component above the photovoltaic module before the high-temperature cloth is removed. The second inspection is carried out simultaneously above and to the side of the photovoltaic module after the high-temperature cloth is removed and the busbar is reshaped.

[0039] See Figures 1-3 As shown, the first drive assembly 41 includes: a first support body disposed along the x-direction on the frame 1, a first power member 412 disposed on the first support body, and a first belt assembly 413 connected to the output end of the first power member 412. The output ends of the second drive assembly 42 and the first belt assembly 413 are connected. The first power member 412 drives the first belt assembly 413, causing the second drive assembly 42 to slide along the x-axis on the first support body. The first power member 412 drives the first belt assembly 413 to rotate cyclically, and the second drive assembly 42 is connected to the belt assembly and is driven. The forward and reverse rotation of the first power member 412 can cause the second drive member to move back and forth along the first direction.

[0040] See Figure 7 As shown, the third drive assembly is connected to the visual inspection mechanism 8. The third drive assembly 43 is driven by the third power component 431. The third drive assembly 43 and the inspection mechanism move synchronously. The second drive assembly 42 is provided with parallel second guide rails 424 and third guide rails 425 along the y-axis. The third drive assembly 43 and the inspection mechanism are respectively movably mounted on the second guide rails 424 and third guide rails 425. The second guide rails 424 and third guide rails 425 are provided along the second direction at the bottom of the second support 423. The third drive assembly 43 is connected to the visual inspection mechanism 8 and the output end of the second drive assembly 42. The second drive assembly 42 includes: a component mounted along the y-axis on the frame. The system comprises a second support body 423, a second power component 422 disposed on the second support body 423, and a second belt assembly 421 connected to the output end of the second power component 422. The output ends of the third drive assembly 43 and the second belt assembly 421 are connected. The second drive assembly 422 drives the second belt assembly 421, causing the third drive assembly 43 to slide along the y-axis direction on the second support body 423. The second drive assembly 422 drives the second belt assembly 421 to rotate cyclically, thereby driving the third drive assembly 43 and the vision inspection mechanism 8. The forward and reverse rotation of the second power component 422 allows the third drive component and the vision inspection mechanism 8 to move back and forth along the second direction.

[0041] See Figures 4-6 , Figure 8As shown, the reference component 64 is detachably mounted on the second telescopic drive component 62. The reference component 64 has a groove on the side near the gripper 63. The size of the reference component 64 is adapted to the wire hole or wire groove of the junction box. The second reference component 64 is detachably mounted on the output end of the second telescopic drive component 62 by bolts, pins, magnetic attraction, or snap-fit. The output end of the second telescopic drive component 62 is provided with an elastic component 54. Specifically, the second telescopic drive component 62 is mounted on the body of the second clamping cylinder via a first block. The second telescopic drive component 62 is fitted with the first block. The bottom of the first block is connected to an elastic telescopic kit. The output end of the elastic telescopic kit is connected to the second block. The mounting base is installed on the bottom of the second block, so that when the reference block is pressed down, it can form an elastic resistance stroke prestress effect, and can also avoid damage to the backsheet of the photovoltaic module. The first telescopic drive component 61, the second telescopic drive component 62, and the third telescopic drive component 823 are any one of servo electric cylinders, servo air cylinders, or servo hydraulic cylinders.

[0042] See Figure 1 As shown, the frame 1 is equipped with a protective cover 2, which has a photovoltaic module inlet 3 and a photovoltaic module outlet. The two ends of the transmission line 7 correspond to the photovoltaic module inlet 3 and the photovoltaic module outlet, respectively. The protective cover 2 on the frame 1 protects the mechanical structure and moving parts, preventing external impurities and dust from affecting the system. The selection of the protective cover 2 takes into account transparency so that the operator can observe the internal status. The protective cover 2 not only protects the photovoltaic modules but also considers the safety of the operator. A reasonable safety design can effectively prevent operators from accidentally entering dangerous areas. The protective cover 2 has a photovoltaic module inlet 3 and an outlet, facilitating the introduction and discharge of photovoltaic modules. This design considers the assembly of photovoltaic modules and the overall process of the production line, ensuring convenient material flow. The two ends of the transmission line 7 correspond to the photovoltaic module inlet 3 and the photovoltaic module outlet, respectively. This allows the photovoltaic modules to be smoothly transferred on the transmission line 7 to complete assembly or other production processes.

[0043] See Figures 4-6 , Figure 8As shown, the bottom of the reference component 64 is provided with a pressure-bearing part 65, the width of the pressure-bearing part 65 is not less than the width of the busbar, and at least the surface of the pressure-bearing part 65 is made of a non-adhesive material. The size of the shovel blade 52 is not less than the clearance groove 67, the elastic element 54 is a tension spring, and supports are respectively provided on both sides of the output end of the first clamping cylinder 51. The shovel blade 52 is rotatably connected to the supports, and the supports are also provided with a stop block. The stop block is used to limit the rotation angle of the shovel blade 52. The two sides of the pressure-bearing part 65 are smooth surfaces to avoid adhesion. The width of the shovel blade 52 is not less than the gripper 63. In this embodiment, the width of the shovel blade 52 is adapted to the inner diameter of the clearance groove 67, and the inner diameter of the clearance groove 67 is adapted to the busbar. The widths of the strips are equal. In some embodiments, the gripper 63 is also provided with an outwardly expanding guide at the opening of the clearance groove 67. The guide is provided on the outside of the clearance groove 67 of the gripper 63 on both sides along the second direction, and the opening of the guide gradually increases outward, so as to correct the deviation of the busbar in the first direction. When the shovel 52 picks up the deviated busbar, the shovel 52 closes inward to push the busbar into the clearance groove 67 along the opening of the guide, so that the axis of the busbar is parallel to the plane of the second direction. In this embodiment, the width of the high temperature part is 30mm, the width of the busbar is 7mm, and the width of the shovel 52 and the inner diameter of the clearance groove 67 are also 7mm.

[0044] The high-temperature fabric tearing device and busbar shaping and detection device of the present invention include the following steps:

[0045] Step S1: Lift the high-temperature fabric from both sides to make it curl up;

[0046] Step S2: Hold the high-temperature cloth and move it upward to tear the high-temperature cloth off the backsheet of the photovoltaic module;

[0047] Step S3: Press the reference component 64 down between the busbars on both sides and maintain a certain prestress;

[0048] Step S4: Push the busbar with the spade 52 to make the busbar fit against the two sides of the reference part 64, and shape the busbar into a shape that fits the two sides of the reference part 64.

[0049] In this embodiment, when the high-temperature cloth is pressed into the solar photovoltaic module in the laminator, the laminator cloth is placed on the top and bottom layers of the photovoltaic module respectively, serving as a cover cloth and pad cloth to shield the busbar and its lead-out holes. The non-stick properties of the high-temperature cloth are used to prevent the EVA film and other materials from sticking to the laminator at high temperatures. In some embodiments, the side of the reference member 64 can also be a stepped surface. Correspondingly, when the clamp 63 is used for shaping, the side of the clamp 63 and the reference member 64 that are close to each other is also a matching stepped surface, so that the busbar can form the corresponding shape. The horizontal line segment of the step can be laid along the wire groove at the bottom of the junction box for one end distance, and then the vertical line segment at the top of the step can be inserted into the junction box.

[0050] It also includes a dispensing mechanism for dispensing adhesive onto photovoltaic modules to ensure the adhesive conforms to the shape of the junction box for bonding. The dispensing mechanism is connected to the output end of the second drive component 42. The dispensing mechanism is an important component of the production line, used to dispense adhesive onto photovoltaic modules to ensure the adhesive conforms to the shape of the junction box, thereby achieving the purpose of bonding the junction box. The dispensing mechanism includes key components such as a dispensing head, a dispensing valve, and a dispensing control system. The dispensing head is connected to the output end of the second drive component 42 to achieve coordinated operation with the entire production line. It can also be equipped with an automatic cleaning system to ensure that the dispensing head is effectively cleaned before and after each use to prevent adhesive residue from affecting the dispensing effect of the next time. Example 2

[0051] This embodiment also discloses a production line, including the high-temperature fabric tearing device and the busbar shaping and detection device described in Embodiment 1.

[0052] The production line described in Embodiment 1 uses a high-temperature tearing device to remove high-temperature cloth from the backsheet of the photovoltaic module and straightens the busbars to facilitate the subsequent installation of junction boxes. The production line also includes an upstream feeding device, which includes a feeding robot and works with an AGV trolley or an external input conveyor belt to feed the photovoltaic module into the high-temperature cloth tearing device. The high-temperature tearing device is also equipped with an adhesive dispensing device and a junction box installation device. Adhesive is applied around the busbars and junction boxes are installed on the shaped busbars. A receiving system is set downstream of the transmission line 7 to receive the processed photovoltaic modules. Example 3

[0053] This embodiment is basically the same as embodiment 1, except that:

[0054] The high-temperature fabric tearing device and busbar shaping and detection device of the present invention include the following steps:

[0055] Step S1: Lift the high-temperature fabric from both sides to make it curl up;

[0056] Step S2: Hold the high-temperature cloth and move it upward to tear the high-temperature cloth off the backsheet of the photovoltaic module;

[0057] Step S3: Align the clamping part 66 with the busbar in the second direction;

[0058] Step S4: Press the reference component 64 down between the busbars on both sides and maintain a certain prestress;

[0059] Step S5: Push the busbar with the gripper 63 to make the busbar fit against the two sides of the reference member 64, and shape the busbar into a shape that fits the two sides of the reference member 64.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

The grippers are provided with clearance grooves not smaller than the size of the busbar, and the reference member is movably disposed between the grippers on both sides. The bottom of the reference component is provided with a pressure-bearing part, the width of which is not less than the width of the busbar, and at least the surface of the pressure-bearing part is made of non-adhesive material. The size of the shovel blade is not less than the clearance groove, and the elastic element is a tension spring. Supports are respectively provided on both output ends of the first clamping cylinder. The shovel blade is rotatably connected to the support. The support is also provided with a stop block, which is used to limit the rotation angle of the shovel blade. A groove is opened on the side of the reference component near the gripper, and the size of the reference component is adapted to the wire hole or wire groove of the junction box. The width of the shovel blade is matched with the inner diameter of the clearance groove. The inner diameter of the clearance groove is equal to the width of the manifold. The gripper is also provided with an outwardly expanding guide at the opening of the clearance groove. The guide is provided on the outside of the clearance groove of the gripper on both sides along the second direction, and the opening of the guide gradually increases outward. The initial tension of the tension spring acting on the upper end of the blade has a greater torque than the plastic stress of the manifold acting on the lower end of the blade. During the shaping of the blade, the third drive component and the first telescopic drive component cooperate. The third drive component moves upward to move the gripper, and the first telescopic drive component on the output end of the third drive component moves downward synchronously. The downward movement speed is equal to the upward movement speed of the third drive component, so that the reference component is stationary relative to the photovoltaic module. It also includes a dispensing mechanism for dispensing adhesive onto the photovoltaic module to adapt the dispensing to the shape of the junction box for bonding the junction box. The dispensing mechanism is connected to the output end of the second drive component. The reference component is detachably mounted on the second telescopic drive component. The second telescopic drive component is mounted on the body of the second clamping cylinder via a first block. The second telescopic drive component is fitted with the first block. An elastic telescopic kit is connected to the bottom of the first block. The output end of the elastic telescopic kit is connected to the second block. The mounting base is installed at the bottom of the second block, so that when the reference component is pressed down, an elastic abutment stroke prestress is formed. The side of the reference component is a stepped surface. When the clamp is used for shaping, the side of the clamp and the reference component that is close to each other is also a matching stepped surface. After the high-temperature cloth is removed, the three-axis drive mechanism aligns any clamping part of the clamp with the busbar in the first direction. The busbar can be clamped and attached to the reference component by closing the first clamping cylinder. The busbar is shaped by the clamp to form the corresponding shape. The horizontal line segment of the step is laid along the wire groove at the bottom of the junction box for one end distance, and then the vertical line segment at the top of the step is inserted into the junction box.
