Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing, specifically a handling device used in coating equipment. Background Technology

[0002] In the photovoltaic module manufacturing field, existing technologies generally adopt a "step-by-step placement" approach for connecting and fixing solder ribbons to solar cells: first, the solder ribbon is precisely laid on the solar cell, then the thin film is covered on the surface of the solder ribbon, and finally, the solder ribbon and solar cell are fixed through the subsequent melting and solidification of the thin film. However, this "solder ribbon first, thin film later" operation mode has a significant risk of solder ribbon misalignment, which directly affects the processing stability and reliability of the module. Because the solder ribbon itself is lightweight, it is only temporarily fixed by the weak friction of the solar cell surface after laying, lacking effective restraint; in addition, the mechanical vibration generated by the equipment operation during the thin film placement process will create a lateral thrust on the solder ribbon, making the originally precisely positioned solder ribbon prone to lateral misalignment. Once the solder ribbon is misaligned, it will further cause processing problems and lifespan risks: in the processing stage, it will lead to uneven bonding of the thin film, solder ribbon, and solar cell during subsequent lamination, increasing the module rework rate, and may also cause short circuits, requiring additional manual inspection and correction, which seriously affects production efficiency. Currently, with the photovoltaic industry's continuous increase in demand for high-efficiency modules, the alignment accuracy requirements for solder ribbons and solar cells have significantly increased, and the traditional "solder ribbon first, thin film later" solution can no longer meet the needs of high-precision manufacturing.

[0015] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0016] like Figure 1As shown, this utility model includes an adsorption device 1 and a clamping device 2. The adsorption device 1 includes a first power drive device 102 and an adsorption component 101. The lower surface of the first power drive device 102 is provided with the adsorption component 101 at intervals and drives the adsorption component 101 to perform lifting and horizontal movements. The clamping device 2 includes a second power drive device 202 and a clamping component 201. The lower surface of the second power drive device 202 is provided with the clamping component 201 at intervals and drives the clamping component 201 to perform lifting and horizontal movements. The first power drive device 102 and the second power drive device 202 respectively drive the adsorption component 101 and the clamping component 201 to move closer to each other horizontally, so that the adsorption component 101 moves between the clamping components 201, and drive the adsorption component 101 and the clamping component 201 to move vertically at the same time, so as to realize the simultaneous movement of the film and the welding ribbon. The operating procedure of this device is as follows: The first power drive device 102 first drives the adsorption component 101 to move vertically downward until it contacts and adsorbs the film; after adsorption is completed, the first power drive device 102 drives the adsorption component 101 to rise vertically to a preset height. At the same time, during the synchronous stage of the first power drive device 102 driving the adsorption component 101 to move downward and adsorb the film, the second power drive device 202 is activated, driving the clamping component 201 to move vertically downward until it contacts and clamps the welding strip; after the clamping component 201 completes the welding strip clamping action, the second power drive device 202 drives it to rise vertically to a specified height, which is lower than the existing height of the adsorption component 101, ensuring that the adsorption component 101 is always above the clamping component 201. Subsequently, the first power drive device 102 drives the adsorption component 101 to move horizontally in the direction of the clamping device 2, while the second power drive device 202 drives the clamping component 201 to move horizontally in the direction of the adsorption device 1. Through the relative movement of the two, the adsorption component 101 is precisely moved into the gap between the clamping components 201, so that the film and the welding ribbon are aligned in planar position in the air. After the film and the welding ribbon are aligned, the first power drive device 102 and the second power drive device 202 start vertically downward simultaneously, driving the adsorption component 101 and the clamping component 201 to move together vertically downward while maintaining their relative positions, until the film and the welding ribbon reach the upper surface of the battery cell simultaneously. Upon reaching the designated position, the adsorption component 101 releases its adsorption force on the film, and the clamping component 201 simultaneously releases its clamping force on the welding ribbon, allowing the film and welding ribbon to be placed stably on the battery cell. After the two are completely released, the first power drive device 102 drives the adsorption component 101 to reset, and at the same time, the second power drive device 202 drives the clamping component 201 to reset. At this point, the entire operation process is completed, the device returns to its initial state, and the next round of handling operations begins.

[0017] like Figure 2As shown, the adsorption device 1 includes a first power drive device 102 and an adsorption assembly 101. The adsorption assembly 101 is spaced at the bottom of the first power drive device 102. The first power drive device 102 includes a first horizontal electric cylinder 1022 and a first vertical electric cylinder 1021. The cylinder body of the first vertical electric cylinder 1021 is arranged vertically, and the cylinder body of the first horizontal electric cylinder 1022 is arranged horizontally. A set of first vertical electric cylinders 1021 are symmetrically arranged on both sides of the first horizontal electric cylinder 1022. This symmetrical layout can achieve balanced and stable force distribution, ensuring uniform transmission of horizontal driving force and avoiding unilateral force deviation. The first vertical electric cylinders 1021 are fixedly connected to each other by a first connecting beam 104. The first connecting beam 104 is fixedly connected to the moving end of the first horizontal electric cylinder 1022, and the first horizontal electric cylinder 1022 drives the first vertical electric cylinder 1021 to move horizontally. The output ends of the two first vertical electric cylinders 1021 are each provided with a first electric cylinder bracket 103. The bottom of the two first electric cylinder brackets 103 is provided with the same connecting rod 105. The first vertical electric cylinders 1021 can synchronously drive the connecting rod 105 to move in the vertical direction. The connecting rod 105 is synchronously driven by the two vertical electric cylinders, which can prevent tilting and shaking and improve the reliability of the structure. The side of the connecting rod 105 is provided with a first slide rail 106. The first slide rail 106 is provided with a first slider, and the first slider is connected to the adsorption assembly 101.

[0018] like Figure 3 and Figure 4As shown, the adsorption assembly 101 includes an L-plate and a suction plate. The L-plate is composed of a horizontal side 1012 and a vertical side 1011 that are perpendicular to each other. The vertical side 1011 is fixedly connected to the first slider through a pre-set mounting hole. With the cooperation of the slider and the slide rail, the entire adsorption assembly 101 can flexibly adjust the horizontal spacing along the first slide rail 106, which can adapt to different film sizes and has strong versatility. A detachable fastening block 107 is provided between the vertical side 1011 and the first slide rail 106. The fastening block 107 is used to fix the adsorption assembly 101 with the adjusted spacing and prevent the adsorption assembly 101 from moving during the operation of the device, which would affect the subsequent adsorption of the film. The adsorption assembly 101 also includes a connecting plate 1014. The horizontal side 1012 is fixedly connected to the connecting plate 1014 by bolts. The connecting plate 1014 and the suction plate are connected by a quick connector 1013. One end of the quick connector 1013 is fixed to the suction plate, and the other end passes through the connecting plate 1014 to form a tight connection. The suction plate adopts a split design, consisting of a cover plate 1015 and a cavity 1016. The cover plate 1015 and the cavity 1016 are sealed to form an internal sealed space. One end of the quick connector 1013 passes through the connecting plate 1014 and communicates with the cavity 1016 of the suction plate, while the other end is connected to a vacuum generator. When the vacuum generator works, it generates negative pressure, creating a pressure difference lower than the external atmospheric pressure inside the cavity 1016. This pressure difference is converted into adsorption force, achieving stable adsorption of the film. To avoid damage to the film due to hard contact during adsorption, a silicone buffer pad 1017 is provided on the lower surface of the cavity 1016. This pad cushions the contact impact force through elastic deformation, thus protecting the film. The working process of the adsorption device 1 is as follows: Adjust the spacing between the adsorption components 101 according to the size of the film. After adjustment, use fastening blocks 107 to fix the adsorption components 101 to the first slide rail 106. The first horizontal electric cylinder 1022 drives the adsorption component 101 above the pre-cut film. The first vertical electric cylinder 1021 is activated, driving the adsorption component 101 to move vertically downward. When the silicone buffer pad 1017 of the bottom suction plate of the adsorption component 101 is completely attached to the upper surface of the film, the suction plate is activated through the negative pressure air source connected to the quick connector 1013. The suction plate generates adsorption force, firmly adsorbing the film onto the surface of the silicone buffer pad 1017. The first vertical electric cylinder 1021 is activated, driving the adsorption component 101 to move upward in the vertical direction until it rises to the preset horizontal transfer height. Then, the first horizontal electric cylinder 1022 is activated, driving the first vertical electric cylinder 1021 and the adsorption component 101 to move horizontally towards the area where the clamping device 2 is located through the first connecting beam 104. The horizontal displacement of the adsorption component 101 is precisely controlled to ensure that the adsorption component 101 can move smoothly into the gap between the clamping components 201, preparing for the subsequent aerial overlap of the film and the welding strip.

[0019] like Figure 5As shown, the gripping device 2 includes a second power drive device 202 and gripping components 201. Gripping components 201 are spaced apart at the bottom of the second power drive device 202. One gripping component 201 is individually positioned at each end of the lower surface of the mounting plate 205. In the middle area, two gripping components 201 are evenly spaced between the two end components in a "group of two" configuration. A single gripping component 201 can only stably grip one end of a welding strip. To prevent each welding strip from falling off during transport and to maintain a horizontal posture, two groups of gripping components 201 must grip both ends. Therefore, the middle area at the bottom of the second power drive device 202 adopts a "group of two gripping components 201" design. Each group of components can precisely correspond to one end of two adjacent welding strips; that is, the two gripping components 201 in a group respectively handle the gripping of one end of the adjacent welding strip. The equal spacing between each group perfectly matches the spacing of the welding strips, ensuring that each end of the welding strip can find a corresponding gripping point. If only single components are arranged at intervals, gaps will appear below the mounting plate 205 where "the ends of the solder strip cannot be gripped," and some solder strips will be unable to be transported stably due to the lack of gripping support at one end. However, the clamping components 201 set separately at both ends of the device only need to grip one end of the solder strip, as the other end can be covered by the clamping components 201 in the adjacent intermediate component group. Ultimately, this achieves the effect that all solder strips are supported at both ends by clamping components 201, ensuring the stability of the transportation process.

[0020] The second power drive device 202 includes a second horizontal electric cylinder 2022 and a second vertical electric cylinder 2021. The cylinder body of the second vertical electric cylinder 2021 is arranged vertically, and the cylinder body of the second horizontal electric cylinder 2022 is arranged horizontally. The second vertical electric cylinders 2021 are symmetrically arranged on both sides of the second horizontal electric cylinder 2022. This symmetrical layout allows for the even transmission of horizontal driving force, avoiding structural displacement caused by unilateral force and improving horizontal movement stability. The second vertical electric cylinders 2021 are fixedly connected to each other by a second connecting beam 203. The second connecting beam 203 is fixedly connected to the moving end of the second horizontal electric cylinder 2022, and the second horizontal electric cylinder 2022 drives the second vertical electric cylinder 2021 to move horizontally. The output end of the second vertical electric cylinder 2021 is provided with a second electric cylinder bracket 204. The bottom of the second electric cylinder bracket 204 is provided with the same mounting plate 205. The two second vertical electric cylinders 2021 on both sides synchronously drive the mounting plate 205, which can prevent it from tilting and swaying during lifting and lowering, and ensure the vertical movement accuracy. The second vertical electric cylinder 2021 can synchronously drive the mounting plate 205 to move in the vertical direction. The lower surface of the mounting plate 205 is provided with a second slide rail 206.

[0021] like Figure 6As shown, the clamping assembly 201 includes a frame 2018. A cylinder 2011 is provided on the top surface of the frame 2018. A fastening plate 2015 is fixedly provided at the bottom of the piston rod 2013 of the cylinder 2011 and drives the fastening plate 2015 to move vertically up and down. A second slider 2012 is also fixedly provided on the top of the frame 2018. The second slider 2012 is installed on both sides of the cylinder 2011. The second slider 2012 is connected to the second slide rail 206 at the bottom of the second power drive device 202. The clamping assembly 201 can adjust the interval between clamping components through the second slide rail 206. A telescopic rod 2014 is located between the top of the frame 2018 and the fastening plate 2015, below the second slider 2012. The bottom of the telescopic rod 2014 is connected to the top of the fastening plate 2015. The telescopic rod 2014 serves as a guide, preventing the fastening plate 2015 from shifting or tilting due to vibration when driven up and down by the cylinder 2011. It also distributes the load, protecting the electric cylinder from damage caused by uneven load, thus extending its lifespan and improving the stability and smoothness of equipment operation. Several notches 2016 are spaced apart along the length of the lower end of the fastening plate 2015. All notches 2016 are designed as isosceles triangles, and the apex of each notch 2016, i.e., the vertex of the isosceles triangle, has a rounded transition structure. This transition structure ensures smooth movement of the gripper when it enters the notch 2016, preventing jamming. A gripper is positioned below each notch 2016 of the fastening plate 2015, and the gripper is assembled to the bottom of the frame 2018. The bottom of the frame 2018 has a hollow area, and the gripper is precisely fixed within this hollow area by a movable pin. The movable pin also serves as the rotation fulcrum of the gripper, ensuring stable rotation of the gripper around the movable pin. The gripper consists of a pair of symmetrically arranged clamping components 2017, connected at the middle by a spring. Structurally, the top of the clamping component 2017, near the notch 2016 of the fastening plate 2015, is in a naturally open state, with its tail in a closed state. Simultaneously, the maximum width of the clamping component 2017 when its top is open is less than the width of the notch 2016 of the fastening plate 2015, ensuring that the notch 2016 can accommodate the tail of the clamping component 2017. In the initial state, the spring is naturally extended, the top of the gripper is open and the tail is closed, and the notch 2016 is aligned vertically with the top of the gripper but not in contact.The working process of clamping device 2: The second horizontal electric cylinder 2022 drives the clamping assembly 201 to move to the designated position, i.e., the position of the cut welding strip. Then, the second vertical electric cylinder 2021 drives the clamping assembly 201 to move downward. During the downward movement, the cylinder 2011 is activated, and the cylinder 2011 drives the fastening plate 2015 to move downward in the vertical direction until the notch 2016 at the lower end of the fastening plate 2015 accommodates the top of the corresponding jaw inside the notch 2016. As the fastening plate 2015 continues to move downward... As the top of the gripper gradually penetrates the notch 2016, since the notch 2016 is an isosceles triangle with an inclined inner wall, the top of the gripper will be subjected to the squeezing force of the inclined inner walls on both sides of the notch 2016 as it continues to penetrate the notch 2016. Under the action of this squeezing force, the tops of the two clamping components 2017 rotate around the movable pin towards the middle and gradually close. At the same time, as the clamping components 2017 rotate synchronously around the movable pin, their tails open to both sides, forming a clamping space that can accommodate the welding strip. After the gripper tail opens to the preset width, the second vertical electric cylinder 2021 also drives the gripper tail to the position of the welding strip. The cylinder 2011 drives the fastening plate 2015 to move upward in the vertical direction. The notch 2016 moves upward synchronously with the fastening plate 2015 and gradually disengages from the top of the gripper. At this time, the spring between the clamping components 2017 pulls the tail of the two clamping components 2017 back to its original length under the action of the restoring force, so that the gripper tail closes in the middle and finally grabs the welding strip located in the tail clamping space. The second vertical electric cylinder 2021 is activated, driving the clamping assembly 201 to move upward in the vertical direction until it rises to the preset horizontal transfer height. Then the second horizontal electric cylinder 2022 is activated, driving the second vertical electric cylinder 2021 and the clamping assembly 201 to move in the horizontal direction towards the area where the adsorption device 1 is located through the second connecting beam 203, preparing for the subsequent air overlap of the film and the welding strip.

[0022] The workflow of this utility model is as follows: First, the first horizontal electric cylinder 1022 and the second horizontal electric cylinder 2022 drive the adsorption component 101 and the clamping component 201 to move to the designated positions, namely the positions of the cut film and the cut welding strip. Then, the first vertical electric cylinder 1021 of the first power drive device 102 is activated, driving the adsorption component 101 to move vertically downward until the silicone buffer pad 1017 of the suction plate adheres to the film; the negative pressure air source supplies air to the suction plate cavity 1016 through the quick connector 1013 to form a negative pressure adsorption film, and then the first vertical electric cylinder 1021 drives the adsorption component 101 to rise to the preset horizontal conveying height in the opposite direction. Simultaneously, the second vertical electric cylinder 2021 of the second power drive device 202 drives the gripping assembly 201 to move vertically downward; at the same time, the cylinder 2011 drives the fastening plate 2015 to move downward, and the isosceles triangular notch 2016 squeezes the top of the gripper to close it and the tail to open it. After the tail of the gripper is aligned with the welding strip, the cylinder 2011 drives the fastening plate 2015 to move upward, and the spring pulls the tail of the gripper to close and grab the welding strip. Then, the second vertical electric cylinder 2021 drives the gripping assembly 201 to rise to a preset height, which is lower than the current horizontal transfer height of the adsorption assembly 101. The first horizontal electric cylinder 1022 drives the adsorption assembly 101 to move towards the gripping device 2, and the second horizontal electric cylinder 2022 drives the gripping assembly 201 to move towards the adsorption device 1. Through relative movement, the adsorption assembly 101 is precisely inserted into the interval of the gripping assembly 201, so that the film and the welding strip are aligned in planar position in the air. After the film and the welding ribbon are aligned, the first vertical electric cylinder 1021 and the second vertical electric cylinder 2021 are activated synchronously, driving the adsorption component 101 and the clamping component 201 to maintain their relative positions and move vertically downwards to a preset position on the upper surface of the battery cell. The adsorption component 101 releases its adsorption, and the film is placed stably on the battery cell; the clamping component 201 simultaneously releases its grippers, and the welding ribbon is released from the grippers and placed on the battery cell, completing the synchronous laying of the film and the welding ribbon. The first power drive device 102 drives the adsorption component 101 to rise vertically first and then move horizontally back to the initial position; at the same time, the second power drive device 202 drives the clamping component 201 to rise vertically first and then move horizontally back to the initial position, and the device returns to its initial state, waiting for the next round of handling operations.
