Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices for shingled welding machines, specifically a feeding device for a photovoltaic shingled welding machine. Background Technology

[0002] In the production and processing of photovoltaic cells, the feeding process of the shingled welding machine is a key process that affects production efficiency and product quality. With the rapid development of the photovoltaic industry, increasingly higher requirements are being placed on the automation level, positioning accuracy, operational stability and cleanliness of cell feeding.

[0003] Currently, traditional photovoltaic (PV) shingling machine feeding devices have many technical problems:

[0004] Adsorption mechanisms mostly use fixed suction cups, lacking a point alignment mechanism after photovoltaic cells are picked up, and lacking a reliable locking mechanism after the photovoltaic cells are aligned. During movement or flipping, the cells are prone to displacement, resulting in a decrease in the accuracy of stacking.

[0005] When feeding solar cells, the alignment structure of the photovoltaic cells has no guiding design, which makes it easy for the alignment structure to make hard contact with the edge of the cells during the alignment process, causing damage to the cells. At the same time, the alignment adjustment speed is slow and it is difficult to meet the needs of high-speed production.

[0006] Based on this, the present invention provides a photovoltaic stacking machine feeding device to solve the problems mentioned in the background art. Utility Model Content

[0007] This utility model addresses the technical problems existing in the prior art by providing a photovoltaic stacking machine feeding device to solve the problem that traditional feeding devices lack a point alignment mechanism for photovoltaic cells and a reliable locking structure during material transfer, which leads to the cells being easily misaligned during movement and flipping.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A photovoltaic stacking welding machine feeding device includes a frame and a material transfer frame that can move on the frame in three axes. The material transfer frame is equipped with a negative pressure pump and an electrically rotatable rotating frame. The bottom surface of the rotating frame is equipped with a positioning locking bladder driven by a pressure regulating pump. The rotating frame is equipped with a set of regularly distributed suction cup modules.

[0009] The suction cup module includes a horizontal slide and two horizontal guide rods. Both horizontal guide rods are fixedly connected to the flipping frame and slidably connected to the horizontal slide. A first spring is fitted on each horizontal guide rod at a position corresponding to both sides of the horizontal slide. A longitudinal guide rod is fixedly installed on the horizontal slide. A locking platform that cooperates with the positioning locking bladder is slidably connected on the longitudinal guide rod. A second spring is fitted on the longitudinal guide rod at a position corresponding to both sides of the locking platform. A vacuum suction cup is installed on the bottom surface of the locking platform. The negative pressure port of the vacuum suction cup is connected to a negative pressure pump.

[0010] It also includes two symmetrically arranged alignment frames. Two double-headed push rods are installed on the flip frame. The two movable ends of each double-headed push rod are connected to the two alignment frames respectively. A set of alignment baffles is installed on the alignment frame. A vision probe is installed on one alignment frame and at the position corresponding to each vacuum suction cup. A pneumatic cleaning module is installed on the other alignment frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. Addressing the problem that traditional feeding devices lack a point alignment mechanism for photovoltaic cells and a reliable locking structure during material transfer, leading to easy displacement of cells during movement and flipping, this utility model achieves a breakthrough improvement through multi-component linkage. In the suction cup module, the transverse slide slides along the transverse guide rod and cooperates with the first spring, allowing for adaptive fine-tuning in the transverse direction. The locking platform slides along the longitudinal guide rod and cooperates with the second spring, allowing for flexible adjustment in the longitudinal direction. Together, they provide the vacuum suction cup with space for fine-tuning the alignment of the cells. When the vision probe detects a deviation in the cell position, the double-headed push rod drives the alignment frame to precisely push the cell to complete the alignment. Subsequently, the pressure regulating pump drives the silicone positioning locking bladder to inflate and expand, tightly squeezing the cross-grid friction texture on the surface of the locking platform to achieve locking. At the same time, the air pressure probe monitors the pressure in real time and feeds it back to the microcontroller, dynamically adjusting the inflation volume to ensure stable locking. This achieves precise alignment and feeding of the photovoltaic stacking machine.

[0013] 2. Traditional alignment structures often suffer from scratches due to the lack of a guiding design, resulting in hard contact with the edges of the solar cells. Furthermore, alignment adjustments are time-consuming and unsuitable for high-speed production. This invention addresses these issues by incorporating a tapered guide head at the front end of the alignment stop. When the double-headed push rod drives the alignment frame closer to the solar cell, the tapered structure first contacts the edge of the solar cell and guides it to its automatic position via the inclined surface. This significantly reduces the resistance and time required for alignment adjustments. Simultaneously, the tapered guide head is coated with a 0.1mm thick rubber coating, which avoids hard contact between the metal and the solar cell. The precise control of the coating thickness ensures that the alignment accuracy is not affected, effectively protecting the integrity of the solar cell edges.

[0014] 3. If dust and impurities adhere to the surface of photovoltaic cells, it will directly lead to defects such as poor welding and desoldering during the stacking process. Traditional manual cleaning methods are inefficient and prone to secondary pollution. The pneumatic cleaning module integrated in this utility model works in deep coordination with the feeding process. Before the vacuum suction cup picks up the cells on the circular conveyor belt, the air cleaning pump draws in clean air through a filter and delivers it to the air cleaning nozzle corresponding to each vacuum suction cup position through the air cleaning nozzle. The clean air is precisely sprayed to remove impurities from the surface of the cells. This design embeds the cleaning process into the feeding process and seamlessly connects with the suction cup adsorption action, effectively improving the cleaning efficiency compared to manual cleaning.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] As a preferred technical solution of this utility model, a microcontroller is installed on the end face of the frame, the data terminal of the vision probe is connected to the microcontroller, a three-axis motion platform is installed on the top of the frame, the three-axis motion platform is connected to the transfer frame, a flip motor is installed on the transfer frame, and the output shaft of the flip motor is fixedly connected to the flip frame.

[0017] As a preferred technical solution of this utility model, it also includes a transmission module installed on the frame, wherein a ring conveyor belt is connected to the transmission module, and the ring conveyor belt conveys photovoltaic cells.

[0018] As a preferred technical solution of this utility model, the pneumatic cleaning module includes an air cleaning pump installed on the flipping frame, an air cleaning nozzle installed on one of the alignment frames, a filter installed at the air inlet port of the air cleaning pump, and the air outlet port of the air cleaning pump connected to the air cleaning nozzle through a pipe. An air cleaning nozzle is connected to the air cleaning nozzle on the air cleaning nozzle and at the position corresponding to each vacuum suction cup.

[0019] As a preferred technical solution of this utility model, the positioning lock bladder is located directly above the locking platform. The positioning lock bladder is made of silicone. The surface of the locking platform is evenly distributed with cross-grid friction textures. A pneumatic probe for monitoring the pressure inside the positioning lock bladder is fixedly installed on the flipping frame. The data terminal of the pneumatic probe is connected to the microcontroller.

[0020] As a preferred technical solution of this utility model, a tapered guide head is fixedly provided at the front end of the alignment stop bar, and a rubber coating is provided on the tapered guide head, the thickness of which is 0.1mm. Attached Figure Description

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] The present invention provides the following preferred embodiments.

[0031] like Figure 1-6 As shown, a photovoltaic stacking welding machine feeding device includes a frame 1 and a transfer rack 2 that can move on the frame 1 in three axes;

[0032] A microcontroller 18 is installed on the end face of the frame 1, and a three-axis motion platform 19 is installed on the top of the frame 1. The three-axis motion platform 19 is connected to the transfer rack 2 via a transmission.

[0033] The transfer rack 2 is equipped with a negative pressure pump 3 and an electrically reversible tilting frame 4. The transfer rack 2 is equipped with a tilting motor 20, and the output shaft end of the tilting motor 20 is fixedly connected to the tilting frame 4.

[0034] As the control core, the microcontroller 18 receives feedback data from components such as the vision probe 17 and precisely controls the three-axis motion platform 19 to drive the material transfer frame 2 to move flexibly in the X, Y, and Z axes. At the same time, it controls the flip motor 20 to drive the flip frame 4 to achieve electric flipping, thereby automating the picking, transferring, and angle adjustment of photovoltaic cells 23.

[0035] The above-mentioned structural design solves the problems of traditional feeding devices that rely on manual or semi-automatic operation, resulting in low accuracy of material transfer position, inaccurate control of flipping angle, and low overall efficiency.

[0036] The bottom surface of the tilting frame 4 is equipped with a positioning locking bladder 6 driven by a pressure regulating pump 5;

[0037] The pressure regulating pump 5 is connected to the positioning lock 6 via a pipeline, and an electromagnetic exhaust valve is installed on the pipeline.

[0038] The pressure regulating pump 5 is mounted on the tilting frame 4;

[0039] The flipping frame 4 is equipped with a set of regularly distributed suction cup modules;

[0040] The suction cup module includes a horizontal slide 7 and two horizontal guide rods 8. Both horizontal guide rods 8 are fixedly connected to the flip frame 4 and are slidably connected to the horizontal slide 7. Each horizontal guide rod 8 is fitted with a first spring 9 at a position corresponding to both sides of the horizontal slide 7.

[0041] A longitudinal guide rod 10 is fixedly installed on the transverse slide 7, and a locking platform 11 that cooperates with the positioning lock 6 is slidably connected on the longitudinal guide rod 10;

[0042] The positioning lock 6 is located directly above the locking platform 11. The positioning lock 6 is made of silicone. The surface of the locking platform 11 is evenly covered with cross-grid friction textures. A pneumatic probe 27 for monitoring the pressure inside the positioning lock 6 is fixedly installed on the flipping frame 4. The data terminal of the pneumatic probe 27 is connected to the microcontroller 18.

[0043] After the two alignment frames 14 complete the alignment of the photovoltaic cells 23, the pressure regulating pump 5 drives the positioning locking bladder 6 to inflate. The silicone positioning locking bladder 6 will squeeze the locking platform 11 below. The cross-grid friction texture on the surface of the locking platform 11 can increase the friction with the positioning locking bladder 6. At the same time, the air pressure probe 27 monitors the pressure inside the positioning locking bladder 6 in real time and transmits the data to the microcontroller 18. The microcontroller 18 dynamically adjusts the inflation amount according to the pressure data to ensure that the locking platform 11 is stably fixed.

[0044] After the position of the locking platform 11 is stabilized, the loading operation of the photovoltaic cells 23 that have been picked up can be completed after the alignment is completed;

[0045] After alignment, the locking state of the locking platform 11 is precisely controllable during material transfer, thereby improving the stability of the suction cup module during adsorption, movement and flipping in the subsequent material loading process, effectively avoiding the offset of photovoltaic cells 23 and greatly improving the positioning accuracy.

[0046] A second spring 12 is fitted on the longitudinal guide rod 10 and on both sides of the locking platform 11. A vacuum suction cup 13 is installed on the bottom surface of the locking platform 11. The negative pressure port of the vacuum suction cup 13 is connected to the negative pressure pump 3.

[0047] It also includes two symmetrically arranged alignment frames 14, and two double-headed push rods 15 are installed on the flipping frame 4. The two movable ends of each double-headed push rod 15 are connected to the two alignment frames 14 respectively. A set of alignment stops 16 are installed on the alignment frame 14.

[0048] A tapered guide head 28 is fixedly provided at the front end of the alignment stop bar 16. The tapered guide head 28 is provided with a rubber coating with a thickness of 0.1mm.

[0049] The coating material is polyurethane rubber;

[0050] When the double-headed push rod 15 drives the two alignment frames 14 to move relative to each other, the conical guide head 28 at the front end of the alignment stop bar 16 will first contact the edge of the photovoltaic cell 23. The cell will be guided to gradually return to its position through the guiding effect of the conical structure. At the same time, the 0.1mm thick rubber coating plays a buffering role during the contact process to avoid damage to the cell from hard contact.

[0051] Traditional alignment bars 16 lack a guiding structure, resulting in low alignment efficiency. Furthermore, their hard contact can easily scratch photovoltaic cells 23, affecting product quality.

[0052] The tapered guide head 28 accelerates the smoothness of alignment guidance and improves alignment efficiency;

[0053] The 0.1mm thick rubber coating ensures a buffering effect and prevents scratches on the solar cells, while the excessive thickness of the coating does not affect the alignment accuracy. This achieves efficient, safe and precise alignment, ensuring the integrity of the photovoltaic cells 23.

[0054] By moving the two alignment frames 14 relative to each other, the photovoltaic cells 23 are kept at a set distance and arranged at set points and at set distances, thereby ensuring the processing accuracy of the photovoltaic stacking machine after loading.

[0055] A vision probe 17 is installed on one alignment frame 14 and at the position corresponding to each vacuum suction cup 13. The data terminal of the vision probe 17 is connected to the microcontroller 18. A pneumatic cleaning module is installed on another alignment frame 14.

[0056] The pneumatic cleaning module includes an air cleaning pump 24 mounted on a flip frame 4, an air cleaning nozzle 25 mounted on an alignment frame 14, an air inlet port of the air cleaning pump 24 with a filter, an outlet port of the air cleaning pump 24 connected to the air cleaning nozzle 25 via a pipe, and an air cleaning nozzle 26 connected to the air cleaning nozzle 25 at the position corresponding to each vacuum suction cup 13.

[0057] Before the vacuum suction cup 13 picks up the photovoltaic cell 23 on the annular conveyor belt 22, the air cleaning pump 24 is working. The air cleaning pump 24 draws in clean air through the filter, which is then transported through the pipeline to the air cleaning nozzle 25. The air cleaning nozzle 26 then sprays clean airflow to each vacuum suction cup 13 and the adsorbed photovoltaic cell 23 to remove dust and impurities attached to the surface.

[0058] The technical problem solved is that impurities are easily adsorbed on the surface of photovoltaic cells 23. Manual cleaning is inefficient and can easily cause secondary pollution, affecting the quality of subsequent stacking welding. The air cleaning nozzle 26 accurately corresponds to the working position, realizing automated cleaning, which not only improves cleaning efficiency but also avoids secondary pollution, effectively ensuring the cleanliness of the cell surface and providing a reliable guarantee for high-quality stacking welding.

[0059] It also includes a transmission module 21 mounted on the frame 1, with a circular conveyor belt 22 connected to the transmission module 21, and photovoltaic cells 23 being transported on the circular conveyor belt 22.

[0060] The transmission module 21 drives the circular conveyor belt 22 to circulate, continuously conveying the photovoltaic cells 23 to be processed to the working range of the transfer rack 2. The suction cup module of the transfer rack 2 can sequentially adsorb and transfer the cells on the conveyor belt, forming a continuous feeding process.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
