Description

Technical Field

[0001] This utility model relates to the field of material transfer device technology, specifically to a non-stop material storage mechanism for photovoltaic module manufacturing. Background Technology

[0002] Currently, when the encapsulant film for photovoltaic modules is changed at the front end of the machine, and during welding, the production line needs to stop to wait for the process to complete. On the one hand, this results in a longer overall process time, reducing the efficiency of the production line; on the other hand, it is not conducive to the allocation of production lines and personnel, causing redundancy and chaos in personnel scheduling. Our organization aims to improve these shortcomings.

[0003] Reference CN207632128U discloses a photovoltaic module storage device, including a frame and a storage mechanism within the frame. The storage mechanism has symmetrically arranged nuts at both ends, each connected to a lead screw. The storage mechanism includes a storage frame fixedly connected to the nuts, with several support frames evenly spaced from top to bottom. Each support frame consists of symmetrically arranged support beams and several trays evenly spaced on the support beams. Several conveying mechanisms are located within the frame; a tray is positioned in the middle of each conveying mechanism. This device stores photovoltaic modules in a stacked manner, but cannot store roll-type encapsulant films, thus not saving processing time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a photovoltaic module manufacturing non-stop material storage mechanism that does not require machine shutdown during front-end material changing and welding, shortens the process time, optimizes the overall process, and improves the overall production capacity.

[0005] To solve the above technical problems, this utility model provides a non-stop material storage mechanism for photovoltaic module manufacturing, including a frame and a ball screw on one side of the frame. A screw nut is installed on the ball screw. Chrome-plated optical shafts are installed at the four corners of the frame. Upper guide roller base plates are slidably arranged on the chrome-plated optical shafts on both sides. Lower guide roller base plates are slidably arranged below the upper guide roller base plates. A screw base is installed on one side of the frame, and the ball screw is installed on the screw base. A connecting corner piece is installed on the screw nut, and the connecting corner piece is installed on the upper guide roller base plate on one side. A lower guide roller is installed between the two upper guide roller base plates. An upper guide roller is installed between the two lower guide roller base plates. Upper synchronous seats are symmetrically arranged on the upper guide roller base plates, and lower synchronous seats are symmetrically arranged on the lower guide roller base plates. A synchronous belt I is arranged between the upper synchronous seats and the lower synchronous seats. The synchronous belt I is installed on a pulley. The pulley is installed on a drive shaft. There are two drive shafts, symmetrically installed on a top seat.

[0006] By adopting the above technical solution, the adhesive film is conveyed from the front end, passing between the upper and lower guide rollers. The ball screw drives the upper substrate of the guide rollers to move, transmitting power to the synchronous belt I, which drives the lower substrate of the guide rollers to move. The adhesive film in the middle is stretched into a serpentine shape, lengthening the movement path and increasing the amount of adhesive film remaining in the mechanism, thus serving as temporary material storage. No machine stoppage is required during front-end material changing and welding, shortening the process time, optimizing the overall process, and improving overall production capacity.

[0007] Preferably, the upper base plate of the guide roller has a lower ear plate, and a lower guide roller is mounted on the lower ear plate. The lower base plate of the guide roller has an upper ear plate, and an upper guide roller is mounted on the upper ear plate.

[0008] By adopting the above technical solution, the lower guide roller has a guide roller screw hole at its end, and the lower guide roller is installed on the lower ear plate with the guide roller screw. The upper guide roller has a guide roller screw hole at its end, and the upper guide roller is installed on the upper ear plate with the guide roller screw. This makes it easy for the adhesive film to pass through the middle of the upper and lower guide rollers after the upper and lower guide rollers are arranged in a cross manner, which facilitates the production line production during the production process.

[0009] Preferably, an upper groove is formed between two pairs of upper ear plates; a lower groove is formed between two pairs of lower ear plates; the upper ear plates fit into the lower grooves, and the lower ear plates fit into the upper grooves.

[0010] By adopting the above technical solution, the ear plate fits the groove, and the structure is stable when the upper and lower base plates of the guide roller are closed, which reduces mechanical vibration during production, reduces shaking of the upper and lower guide rollers, reduces film slippage, and improves production efficiency.

[0011] Preferably, a lower guide roller is distributed between each pair of upper guide rollers.

[0012] By adopting the above technical solution, the upper guide roller and the lower guide roller are distributed in a cross pattern. When the upper guide roller moves downward and the lower guide roller moves upward, the adhesive film can be stretched into a serpentine shape, which is beneficial for material changing and material storage during welding.

[0013] Preferably, bearings are installed on both sides of the upper substrate of the guide roller, and these bearings are slidably mounted on the chrome-plated optical shaft.

[0014] Preferably, bearings are also installed on both sides of the guide roller lower substrate, and these bearings are also slidably mounted on the chrome-plated optical shaft.

[0015] By adopting the above technical solution, the upper and lower base plates of the guide roller are lubricated and installed on the chrome-plated optical shaft through bearings, which avoids frictional damage between the upper and lower base plates of the guide roller and the chrome-plated optical shaft, improves the service life of the mechanism, and avoids sliding jamming, thereby improving production efficiency.

[0016] Preferably, a synchronous pulley is also installed on the drive shaft, and the synchronous pulley is located outside the pulley; a synchronous belt II is installed on the two synchronous pulleys.

[0017] By adopting the above technical solution, the structure of installing synchronous belt II on the synchronous pulley on the outer side of the pulley can keep the left and right synchronous pulleys at the same speed, so that the two sides of the guide roller upper plate are evenly stressed and the guide roller upper plate is prevented from tilting.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this invention, the adhesive film is conveyed from the front end, passing between the upper and lower guide rollers. A ball screw drives the upper substrate of the guide rollers to move, transmitting power to the synchronous belt I, which in turn drives the lower substrate of the guide rollers. The adhesive film in the middle is stretched into a serpentine shape, lengthening the movement path and increasing the amount of adhesive film remaining in the mechanism, thus serving as temporary material storage. No machine stoppage is required during front-end material changes and welding, shortening the process time, optimizing the overall process, and improving overall production capacity.

[0020] 2. The upper base plate of this utility model has a lower ear plate, on which a lower guide roller is mounted; the lower base plate of the guide roller has an upper ear plate, on which an upper guide roller is mounted. The configuration of the upper and lower ear plates facilitates the passage of the adhesive film between the upper and lower guide rollers after they are arranged in a cross pattern, which is convenient for production on the production line.

[0021] 3. In this utility model, an upper groove is formed between two pairs of upper ear plates; a lower groove is formed between two pairs of lower ear plates; the upper ear plate matches the lower groove, and the lower ear plate matches the upper groove. When the upper base plate and the lower base plate of the guide roller are closed, the structure has good stability, reduces mechanical vibration during production, reduces shaking of the upper and lower guide rollers, reduces film slippage, and improves production efficiency.

[0027] like Figure 1 As shown, the photovoltaic module manufacturing non-stop material storage mechanism includes a frame and a ball screw 1 on one side of the frame, with a nut 15 mounted on the ball screw 1. The frame includes a base 22, a top seat 23, and a column (not shown in the figure). A chrome-plated optical axis 9 is mounted at each of the four corners of the frame. An upper guide roller substrate 3 and a lower guide roller substrate 4 are slidably mounted on two chrome-plated optical axes 9 on one side of the frame, and the upper guide roller substrate 3 and the lower guide roller substrate 4 are also slidably mounted on two chrome-plated optical axes 9 on the other side of the frame. The upper guide roller substrate 3 is located above the lower guide roller substrate 4.

[0028] like Figure 2 As shown, the upper base plate 3 of the guide roller has a lower ear plate 18, on which a lower guide roller 5 is mounted; the lower base plate 4 of the guide roller has an upper ear plate 19, on which an upper guide roller 7 is mounted. The upper guide roller 7 is located above, and the lower guide roller 5 is located below. This design facilitates the film passing between the upper guide roller 7 and the lower guide roller 5 after they are arranged crosswise, thus facilitating production on the production line.

[0029] An upper groove 21 is formed between two pairs of upper ear plates 19; a lower groove 20 is formed between two pairs of lower ear plates 18; the upper ear plates 19 and the lower grooves 20 fit together, and the lower ear plates 18 and the upper grooves 21 fit together. When the ear plates and grooves fit together, the upper base plate 3 and the lower base plate 4 of the guide roller are closed, resulting in good structural stability, reducing mechanical vibration during production, reducing shaking of the upper guide roller 7 and the lower guide roller 5, reducing film slippage, and improving production efficiency.

[0030] A lower guide roller 5 is distributed between each pair of upper guide rollers 7. The upper guide rollers 7 and lower guide rollers 5 are distributed in a cross pattern. When the upper guide roller 7 moves downward, the lower guide roller 5 moves upward, which can stretch the film into a serpentine shape, which is beneficial for material changing and material storage during welding.

[0031] like Figure 3As shown, bearings 14 are installed at the center of both sides of the upper guide roller base plate 3, and these bearings 14 are slidably mounted on the chrome-plated optical shaft 9. Bearings 14 are also installed at the center of both sides of the lower guide roller base plate 4, and these bearings 14 are also slidably mounted on the chrome-plated optical shaft 9. The bearings 14 lubricate the upper guide roller base plate 3 and the lower guide roller base plate 4 on the chrome-plated optical shaft 9, preventing frictional damage between them and extending the service life of the mechanism. They also prevent slippage and jamming, thus improving production efficiency. Fixed connecting shafts 6 are installed on both sides of the top of the upper guide roller base plate 3, and fixed connecting shafts 6 are also installed on both sides of the bottom of the lower guide roller base plate 4, providing stability.

[0032] A screw base 24 is bolted to one side of the frame, and the ball screw 1 is rotatably mounted on the screw base 24. The screw base 24 mainly consists of a vertical plate and a horizontal plate. A support plate is fixed to the bottom of the long vertical plate. Ball bearings are installed at both ends of the ball screw 1, and the ball bearings are mounted on the vertical plate. The top of the vertical plate is fixed to the top seat 23, the bottom of the vertical plate is mounted on the horizontal plate, and the horizontal plate is mounted on the column. The motor 8 is mounted on the support plate at the bottom of the vertical plate. The output shaft of the motor 8 is connected to the ball screw 1 via a transmission, which is existing technology. A connecting angle piece 14 is installed on the screw nut 15, and the connecting angle piece 14 is mounted on the upper base plate 3 of the guide roller on one side. The transmission structure of the ball screw 1 is simple and reliable, and has a long service life. A lower guide roller 5 is installed between the two upper base plates 3 of the guide roller, and an upper guide roller 7 is installed between the two lower base plates 4 of the guide roller. In this embodiment, the lower guide roller 5 is an aluminum lower guide roller, and the upper guide roller 7 is an aluminum upper guide roller.

[0033] The adhesive film is conveyed from the front end, passing between the upper guide roller 7 and the lower guide roller 5, and then transferred to the next mechanism. Upper synchronous seats 16 are symmetrically arranged on the upper base plate 3 of the guide roller, and lower synchronous seats 17 are symmetrically arranged on the lower base plate 4 of the guide roller. A synchronous belt I11 is arranged between the upper synchronous seats 16 and the lower synchronous seats 17. One end of the synchronous belt I11 is bolted to the upper synchronous seat 16, and the other end is bolted to the lower synchronous seat 17. The synchronous belt I11 meshes with the pulley 10 for transmission. The structure of the synchronous belt I11 mounted on the upper base plate 3 and the lower base plate 4 of the guide roller via the upper synchronous seats 16 and the lower synchronous seats 17 allows the upper base plate 3 and the lower base plate 4 of the guide roller to rise and fall at the same speed, and facilitates maintenance and replacement of the mechanism. The pulley 10 is mounted on the drive shaft 2; there are two drive shafts 2, symmetrically mounted on the top seat 23.

[0034] In another embodiment, such as Figure 4As shown, a synchronous pulley 13 is also installed on the drive shaft 2, and the synchronous pulley 13 is located outside the pulley 10; a synchronous belt II 12 is installed on the two synchronous pulleys 13. The movement of the synchronous belt I 11 drives the drive shaft 2 to rotate, which in turn drives the synchronous pulleys 13 to rotate. The rotation of the synchronous pulleys 13 drives the synchronous belt II 12 to move. The structure of installing the synchronous belt II 12 on the synchronous pulleys 13 outside the pulley 10 can keep the left and right synchronous pulleys 13 at the same speed, so that the two sides of the guide roller upper plate 3 are evenly stressed, and the guide roller upper plate 3 is prevented from tilting.

[0035] When the front-end sensor detects that the diameter of the material roll is less than a set threshold, the mechanism of this application will be activated. During operation, the motor 8 drives the ball screw 1, which in turn moves the upper guide roller base plate 3, transmitting power to the synchronous belt I11. The synchronous belt I11 pulls the lower guide roller base plate 4, thus moving the upper guide roller 7 and the lower guide roller 5 up and down. Because the upper guide roller 7 is mounted on the lower guide roller base plate 4, and the lower guide roller 5 is mounted on the upper guide roller base plate 3, the upper guide roller 7 moves downwards and the lower guide roller 5 moves upwards, stretching the adhesive film in the middle into a serpentine shape, lengthening the movement path, and increasing the amount of adhesive film remaining in the mechanism, thus serving as temporary material storage. No machine stoppage is required during front-end material changes and welding, shortening the process time, optimizing the overall process, and allowing long production lines to avoid stopping production every time a material is changed, thus improving overall capacity and facilitating personnel arrangement and allocation. When the material changing and welding steps at the front end are completed, the adhesive film in the material storage mechanism is basically consumed. The motor 8 will slowly move the upper guide roller 7 and the lower guide roller 5 towards the middle through a series of transmission controls. The mechanism will be activated again during the next material changing and welding.
