Description

Technical Field

[0001] The utility model relates to the technical field of string welding machines, in particular to a suction cup structure for string welding machines. Background Art

[0002] Solar cell modules are the products that photovoltaic manufacturers ultimately deliver to users. Solar cell modules need to first be welded one by one with soldering tape (usually tinned copper tape) through a stringing machine to form a battery string, and then undergo packaging and other processes to form a photovoltaic module unit for power generation. In the manufacture of solar cell modules, the precise transmission and welding of soldering tapes are crucial steps. Traditional stringing machine technology is to weld the cells and soldering tapes one by one on an automated assembly line, and the welded cells are continuously conveyed forward to achieve series welding between the cells. However, during the welding and transmission process of the soldering tape, there are problems with the adsorption structure of the soldering tape as follows:

[0003] (1) Traditional solder strip suction devices can usually only fix and suck a certain number and specific size of solder strips, which means that every time the specifications or quantity of the solder strips are changed during the production process, the structure of the suction cup needs to be redesigned, which increases the manufacturing cost and time cost, and also increases the adjustment and downtime of the production line.

[0004] (ii) Since impurities may be generated after welding, it is difficult for the existing fixed adsorption structure to effectively remove the impurities on the surface of the suction cup, which may lead to a decrease in the adsorption effect of the suction cup and further affect the welding quality. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a suction cup structure for a string welding machine to solve one or more problems in the prior art.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The suction cup structure for a string welding machine includes a first plate body and a second plate body fixedly connected to the first plate body. The first plate body is composed of a mounting surface for fixing to the second plate body and an adsorption surface for adsorbing the welding strip. An adsorption cavity is formed between the mounting surface and the adsorption surface.

[0008] Furthermore, the mounting surface is provided with a first mounting hole, the second plate body is provided with a second mounting hole, and the first mounting hole and the second mounting hole are fixedly connected by a fastener.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

The first plate body is composed of a mounting surface for fixing to the second plate body and an adsorption surface for adsorbing the welding strip.

[0031] The specific structure of the suction cup structure for the string welding machine is described below:

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 3 The suction cup structure for a string welding machine includes a first plate body 1 and a second plate body 2 fixedly connected to the first plate body 1. Specifically, the first plate body 1 is a suction cup for adsorbing photovoltaic welding strips. The photovoltaic welding strips are used to connect the electrical performance of the battery cells inside the component. They are made of high-purity copper as a substrate and a tin layer is coated on the surface. On the one hand, it prevents the copper substrate from oxidizing and discoloring, and on the other hand, it is convenient to weld the material to the grid line of the battery. The first plate body 1 is composed of a mounting surface 101 for being fixedly connected to the second plate body 2 and an adsorption surface 102 for adsorbing the welding strip. An adsorption cavity is formed between the mounting surface 101 and the adsorption surface 102.

[0034] Furthermore, the mounting surface 101 defines a first mounting hole 1010, and the second plate body 2 defines a second mounting hole 201. The first mounting hole 1010 and the second mounting hole 201 are fixedly connected by fasteners. Specifically, the number, size, and position of the first mounting hole 1010 and the second mounting hole 201 are correspondingly arranged, and the first mounting hole 1010 and the second mounting hole 201 are connected by fasteners to achieve a fixed connection between the first plate body 1 and the second plate body 2. The fasteners can be screws or bolts, as long as they can fix the first plate body 1 and the second plate body 2. No excessive restrictions are made here. Preferably, in the present embodiment, the first mounting hole 1010 and the second mounting hole 201 are respectively arranged at the edge connection of the mounting surface 101 and the second plate body 2.

[0035] Furthermore, the mounting surface 101 also has a first adsorption hole 1011, so that the vacuum equipment can extract the air pressure on the adsorption surface 102. The second plate body 2 also has a third mounting hole 202. The third mounting hole 202 has a built-in connector 203. One end of the connector 203 is connected to the vacuum equipment through a pipe (not shown in the figure). The pipe is also provided with a solenoid valve (not shown in the figure) for controlling the opening and closing of the airway. The vacuum equipment is a common technology in this field and will not be elaborated on here. The other end of the connector 203 passes through the third mounting hole 202 and is connected to the first adsorption hole 1011.

[0036] Further, the adsorption surface 102 has at least two protrusions 1022. Specifically, in the present embodiment, the number of the protrusions 1022 can be set according to the required number of solder strips. A plurality of the protrusions 1022 are evenly arranged on the adsorption surface 102 along a first direction. The protrusions 1022 are in the shape of long strips. A adsorption position 10220 for adsorbing the solder strip is provided in the protrusion 1022. The adsorption position 10220 has a second adsorption hole 10221. Specifically, the number of the second adsorption holes 10221 can be single or multiple, as long as the solder strip can be adsorbed. No excessive restrictions are made here. When the number of the second adsorption holes 10221 is multiple, the multiple second adsorption holes 10221 are evenly distributed in the adsorption position 10220 to ensure the uniformity and stability of the solder strip adsorption. The second adsorption hole 10221 and the first adsorption hole 1011 are both connected to the adsorption cavity.

[0037] Furthermore, the size of the adsorption position 10220 is adapted to the size of the solder strip, so that the solder strip can be completely adsorbed in the adsorption position 10220, thereby ensuring the stability of the solder strip adsorption.

[0038] Furthermore, a detection hole 10222 is also provided at the end of the protrusion 1022, and the detection hole 10222 has a built-in detection element 10223. Specifically, the detection element 10223 can be a visual sensor or a laser sensor, which only needs to realize automatic alignment of the solder strip and ensure that the solder strip is adsorbed to the correct position. No excessive restrictions are made here, and the stable and correct position can always be maintained during the transmission process, thereby improving the use effect and efficiency of the equipment.

[0039] Furthermore, the protrusion 1022 is fixedly connected to the adsorption surface 102, and the adsorption surface 102 is provided with at least two first positioning holes 1020. Preferably, in the present embodiment, the plurality of first positioning holes 1020 may be any one of waist-shaped holes, bar-shaped holes or circular holes. The plurality of first positioning holes 1020 may be arranged at the end of the adsorption surface 102, or may be arranged in the middle of the second adsorption surface 102, as long as the protrusion 1022 can be fixed. The protrusion 1022 is connected to the first positioning hole 1020 by fasteners. Specifically, in the present embodiment, the plurality of first positioning holes 1020 are evenly arranged on the adsorption surface 102 along the first direction, and the number of the first positioning holes 1020 is the same as the number of the protrusions 1022. By means of fastener connection, when it is necessary to adsorb welding strips of other sizes, the protrusions 1022 of the corresponding size may be directly replaced to meet different adsorption requirements without redesigning and replacing the entire first plate body 1, thereby improving the practicability of the device.

[0040] The specific working process of the sucker structure for the string welding machine described in the embodiment of the utility model is described as follows:

[0041] The corresponding protrusion 1022 is installed according to the requirement of soldering tape adsorption. When the soldering tape needs to be adsorbed, the solenoid valve controls the vacuum machine to open, and the vacuum machine forms a negative pressure in the second adsorption hole 10221 through the joint 203, the first adsorption hole 1011 and the adsorption chamber, thereby adsorbing the soldering tape. When the soldering tape needs to be released, the solenoid valve controls the airway to close, and the vacuum machine breaks the vacuum environment in the second adsorption hole 10221 through the joint 203 and the first adsorption hole 1011, thereby releasing the soldering tape.

[0042] Embodiment 2

[0043] This embodiment has the same structure as the first embodiment, except for the following differences:

[0044] Please refer to Figure 4, the protrusion 1022 is movably arranged on the adsorption surface 102, and the adsorption surface 102 is provided with a second positioning hole 1021, and the second positioning hole 1021 is laid on the adsorption surface 102 along the second direction. Specifically, the first direction and the second direction are perpendicular to each other, that is, the second positioning hole 1021 and the protrusion 1022 are perpendicular to each other. The second positioning hole 1021 can be arranged at the end of the adsorption surface 102, or at the middle of the second adsorption surface 102. The second positioning hole 1021 can be any one of a waist-shaped hole and a strip hole. No excessive restrictions are made here. It is only necessary to meet the requirement that the protrusion 1022 can be fixed. The protrusion 1022 is movably connected with the second positioning hole 1021. Specifically, the protrusion 1022 can slide in the second positioning hole 1021 along the second direction. Therefore, the position of the protrusion 1022 can be adjusted in the second positioning hole 1021 and then fixed with a fastener, thereby realizing the adsorption requirements of different numbers of welding strips and improving the practicality and use efficiency of the device.

[0045] Embodiment 3

[0046] Most of the structures of this embodiment are the same as those of the first and second embodiments, and the differences are as follows:

[0047] Please refer to Figure 5 The suction cup structure also includes a cleaning component 3, and the cleaning component 3 includes a cleaning frame 301, and the cleaning frame 301 is movably arranged on the first plate body 1. A driving member 302 is arranged on one side of the cleaning frame 301. The cleaning frame 301 has a plurality of cleaning brushes 3010 on the side facing the adsorption surface 102, and the cleaning brushes 3010 are movably in contact with the protrusions 1022. Specifically, the cleaning brushes 3010 are evenly distributed on the cleaning frame 301, and the height of the cleaning frame 301 is higher than the height of the protrusions 1022, and the cleaning brushes 3010 and the protrusions 1022 are correspondingly arranged to ensure that each protrusion 1022 can be cleaned.

[0048] Furthermore, the first surface and the second surface of the first plate body 1 are both provided with tracks 1023, and sliders 3011 are both provided at the two ends of the cleaning frame 301, and the other surface of the slider 3011 can be movably arranged on the track 1023. Specifically, the first surface of the first plate body 1 refers to the front end surface of the first plate body 1, the second surface refers to the adsorption surface 102 of the first plate body 1, the first side refers to one side of the front end surface of the first plate body 1, and the second side refers to one side of the adsorption surface 102 of the first plate body 1. When the first plate body 1 is adsorbed, the cleaning frame 301 can be moved along the slider 3011 The track 102 moves to the front end of the first plate body 1 without affecting the adsorption of the welding strip. When the adsorption surface 102 of the first plate body 1 needs to be cleaned, the cleaning frame 301 can be moved along the track 1023 to the adsorption surface 102. Furthermore, the cleaning frame 301 is driven to move on the track 1023 by the driving member 302. The cleaning brush 3010 moves in the protrusion 1022 as the cleaning frame 301 moves, thereby removing impurities in the protrusion 1022, ensuring the adsorption effect of the suction cup structure on the welding strip, and further improving the transmission and welding efficiency of the welding strip.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
