Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic equipment technology, specifically to a tape conveying and bonding device for a tape applicator. Background Technology

[0002] The rapid development of the solar photovoltaic industry has led to increasingly higher demands for production efficiency. Traditional manual tape application methods are inefficient and labor-intensive, and can no longer meet the needs of large-scale production. Automated tape application equipment can achieve fast and accurate tape application, greatly improving production efficiency and reducing production costs. Automated tape application equipment can precisely control parameters such as the application position, length, and tension of the tape, ensuring the consistency and stability of product quality. In contrast, manual tape application is easily affected by human factors, leading to inaccurate tape application positions and inconsistent lengths, which affect the performance and appearance of photovoltaic panels. To automate and accelerate tape application, devices that can automatically and continuously apply tape have been designed.

[0003] A rotary joint for automatically applying adhesive tape is disclosed in patent document CN214788428U. It includes a rotating shaft, a housing, a connecting plate, a first rotating shaft hole, a second rotating shaft hole, a fixing nut, threads, and bearings. The rotating shaft has several first and second rotating shaft holes on its surface, with each hole corresponding to and communicating with the others. A connecting plate is mounted around the circumference of the housing. Bearings are installed on both sides of the housing where they connect to the rotating shaft. The rotating shaft is inserted into and passes through the housing from the right side. The fixing nut connects to the threads on the rotating shaft to limit its movement. This invention is reasonably designed. This rotary joint uses several small holes to draw in the adhesive tape. When the automatic walking device applies the tape to a glass plate, one of the holes provides positive air pressure, blowing onto the tape. Then, a mechanical shear automatically cuts the tape, and the film adheres to the glass plate. This process is repeated to complete the next action, resulting in a high degree of automation.

[0004] However, since it directly adsorbs the tape by making a hole in a rotating shaft, the adsorption area is relatively small. During operation, the tape may fall off the rotating shaft, causing the equipment to malfunction. Utility Model Content

[0005] The problem this invention aims to solve is that the adhesive tape adsorption area of ​​the adhesive roller is small, making it easy for the tape to fall off during operation.

[0006] To achieve the above objectives, the technical solution of this utility model is: a tape conveying and bonding device for a tape applicator, comprising a fixed plate, on which a tape applicator and a driving device are disposed, the tape applicator and the driving device being connected in transmission; the tape applicator includes a tape applicator rotating shaft, on which four or more air passages are provided; at one end of the tape applicator rotating shaft, a connector is fitted, on which four or more first air holes are provided, the first air holes being connected to the air passages.

[0007] Four or more transfer components are provided at the end of the adhesive application shaft. The transfer components are evenly distributed radially along the adhesive application shaft. Each transfer component includes a connector and an adhesive application component. The connector has a second air hole that communicates with the first air hole. The top of the connector has a fixing groove that communicates with the second air hole. The bottom of the adhesive application component has a snap-fit ​​part that can be inserted into the fixing groove to fix the adhesive application component to the connector. The adhesive application component has a third air hole that communicates with the fixing groove.

[0008] In this design, multiple transfer components are connected radially around the adhesive application axis. Each transfer component consists of a connector and an adhesive application component. The connector has a second air hole that communicates with the air passage, and the adhesive application component has multiple third air holes that communicate with the second air holes. The adhesive tape on the adhesive application component is adsorbed or blown away through the third air holes. The multiple third air holes of the adhesive application component divide the air volume of one second air hole on the connector into multiple portions, thereby increasing the adsorption area of ​​the adhesive application component. When applying adhesive, the tape is less likely to fall off from the adsorption area. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 6As shown, a tape conveying and bonding device for a tape applicator includes a fixing plate 1. The fixing plate 1 is provided with a tape applicator 2, a driving device 3, and a tape roll fixing device 5. The tape applicator 2 and the driving device 3 are connected by a transmission. The tape roll is fixed on the tape roll fixing device 5. The tape applicator 2 includes a tape applicator shaft 21. The tape applicator shaft 21 has four or more air passages 22. An adapter 23 is sleeved on one end of the tape applicator shaft 21. The adapter 23 has four or more first air holes 231, which are connected to the air passages 22.

[0017] In this embodiment, the multi-air-path design can provide a more uniform adsorption force for tape conveying. When conveying tape, multiple air paths work together to ensure that the tape is stably adsorbed during the rotation of the adhesive-applying shaft 21, and there will be no local loosening or displacement of the tape.

[0018] Four or more transfer members 24 are provided at the end of the adhesive application shaft 21. The transfer members 24 are evenly distributed radially along the adhesive application shaft 21. This makes the force on the tape more uniform in all directions during the process of transferring the tape from the adhesive application shaft 21 to the silicon plate. The uniform force helps to maintain the flatness and positional accuracy of the tape, avoids wrinkles or positional deviations of the tape during the transfer process, and thus ensures that the tape can be accurately adhered to the target object.

[0019] like Figure 2 and Figure 5 As shown, the transfer component 24 includes a connector 241 and an adhesive component 242. The connector 241 is provided with a second air hole 243. The first air hole 231 of the adapter 23 is connected to a first air nozzle 233 on the side near the transfer component 24, and the second air hole 243 is connected to a second air nozzle 247 on the side near the adapter 23. An air tube 28 is connected between the first air nozzle 233 and the second air nozzle 247, so that the second air hole 243 communicates with the first air hole 231. A fixing groove 244 is provided on the top of the connector 241, and the second air hole 243 communicates with the fixing groove 244.

[0020] The bottom of the adhesive applicator 242 is provided with a snap-fit ​​part 245, which can be inserted into the fixing groove 244 to fix the adhesive applicator 242 to the connector 241. This snap-fit ​​design makes the replacement of the adhesive applicator 242 very convenient. When the adhesive applicator 242 is worn or needs to be replaced with a different type of adhesive applicator 242, the operator can easily pull out the old adhesive applicator 242 and insert the new one. Compared with traditional one-piece or complex connection methods, this snap-fit ​​design greatly shortens the time for equipment maintenance and component replacement, and improves efficiency. Production efficiency; the adhesive applicator 242 has a third air hole 246, which is connected to the fixing groove 244; the third air hole 246 on the adhesive applicator 242 is connected to the second air hole 243 and the first air hole 231 through the fixing groove 244. This means that while ensuring that the adhesive applicator 242 can effectively adsorb the tape, its own structure is relatively independent. Replacing the adhesive applicator 242 will not affect the normal operation of the entire air circuit system. This design allows the equipment to quickly return to working status after the adhesive applicator 242 is replaced, reducing the time and workload of equipment debugging.

[0021] like Figure 4 As shown, in this embodiment, a flange seat 25 is provided on the fixing plate 1, and the adhesive application shaft 21 is rotatably disposed in the flange seat 25. The flange seat 25 has two or more suction holes 251 and one blowing hole 252. In this embodiment, five suction holes 251 are provided on the flange seat 25. The air passage 22, through the rotation of the adhesive application shaft 21, alternately communicates with the suction holes 251 and the blowing hole 252. Air nozzles are connected to each of the five suction holes, and air is supplied to the air passage 22 in the adhesive application shaft 21 through the air nozzles. When the air passage 22... When the suction port 251 is connected, an adsorption force is generated, which adsorbs the tape onto the adhesive part 242 of the transfer member 24, thereby achieving stable tape delivery. When the air passage 22 is connected to the blowing port 252, the blown gas can help separate the tape. After the tape is bonded to the silicon substrate, the air blowing port 252 allows the tape to be more easily detached from the adhesive part 242 of the transfer member 24, ensuring that the tape can be accurately bonded to the silicon substrate without the tape sticking to the adhesive part 242, thus improving the efficiency and quality of tape bonding.

[0022] In this embodiment, the adapter 23 is provided with a connecting groove 232 that communicates with the first air hole 231. A sealing element 26 is sleeved between the transfer member 24 and the flange seat 25. The sealing element 26 is attached to the flange seat 25, and the adapter 23 is attached to the sealing element 26. The sealing element 26 and the groove wall of the connecting groove 232 form a connecting air passage 261, so that the first air hole 231 is connected to the air passage 22. The sealing element 26 enhances the sealing performance of the entire air passage system, prevents gas leakage during equipment operation, and ensures stable air pressure in the air passage.

[0023] like Figure 6As shown, in this embodiment, a limiting member 27 is provided between the adapter 23 and the transfer member 24, so that there is a distance between the adapter 23 and the transfer member 24, providing a stable space for the air circuit connection.

[0024] In this embodiment, the transfer member 24 is also provided with a first gasket 29 on the side near the adapter 23. U-shaped grooves 291 are uniformly arranged along the radial direction of the first gasket 29. The second air nozzle 247 passes through the U-shaped groove 291 and connects to the second air hole 243. The first gasket 29 can provide a certain support and fixation for the second air nozzle 247, reduce the shaking and displacement of the second air nozzle 247, thereby improving the stability of the air circuit connection and ensuring the smooth flow of the air circuit.

[0025] like Figures 2 to 3 As shown in this embodiment, a cutting device 4 is also provided on the fixing plate 1. The cutting device 4 includes a cutting part 41 and a fixing seat 42. The fixing seat 42 is connected to the fixing plate 1, and the cutting part 41 is movably connected to the fixing seat 42. A cutting groove 248 is formed between adjacent transfer members 24. When cutting the tape, the cutting part 41 of the cutting device 4 can be inserted into the cutting groove 248. During the cutting process, the wall of the cutting groove 248 can provide a certain support for the tape, preventing the tape from being excessively deformed or torn due to force during cutting. This helps to maintain the flatness and integrity of the tape cutting edge, ensuring that the cut tape can better meet the subsequent bonding requirements.

[0026] like Figure 1 As shown in this embodiment, a sensing device 6 is provided between the adhesive applicator 2 and the tape roll fixing device 5. During operation, the tape passes under the sensing device 6. When no tape passes under the sensing device 6, the system can determine that the tape has been used up and promptly remind the operator to replace the tape roll to avoid production interruption due to tape depletion.

[0027] The entire device is designed with multiple air passages 22 through the adhesive application shaft 21, and the multiple air passages 22 are connected to the evenly distributed transfer components 24. The air volume in the air passages 22 of the transfer components 24 is increased by the diversion of the multiple third air holes 246 of the adhesive application component 242, thereby increasing the area of ​​adsorption or blowing of the tape. This achieves stable adsorption and bonding of the tape during the conveying process, which ensures that the tape can be conveyed to the bonding position at a uniform speed and state, without problems such as loosening, offset, or wrinkles, effectively ensuring the accurate bonding of the tape.
