Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing equipment technology, specifically an automatic feeding device for a battery screen printing machine. Background Technology

[0002] In the manufacturing process of solar cells, the screen printing process is crucial, directly affecting the printing quality of the cell electrodes and consequently influencing the cell's performance and yield. With the rapid development of the battery industry, more stringent requirements have been placed on the automation level, printing accuracy, and production efficiency of screen printing machines. As the front-end component of the screen printing machine, the performance of the automatic feeding device directly determines the stability and efficiency of the entire printing process. In existing battery screen printing processes, solar cells are manually placed on a conveyor belt, which moves them to the first flipping area. A specific flipping mechanism flips the cell so that the side to be printed faces upwards, and then the printing machine performs the printing. After printing, a lamp is used to cure the paste on the cell surface. Then, a second flipping mechanism flips the cell back to its initial state, and finally, a transport mechanism removes it. However, existing battery flipping mechanisms typically lack limiting mechanisms. During the battery flipping process, the battery itself may float due to factors such as insufficient precision in the flipping sheet structure design and inertia during rotation. Furthermore, friction between the battery and the transport mechanism, such as uneven conveyor belt surfaces or uneven friction between the battery cells and the conveyor belt, can easily cause battery position deviation. Once the battery position deviates, the printed pattern cannot accurately match the battery electrode positions in subsequent printing stages, thus affecting the printing effect. Therefore, it is necessary to research an automatic feeding device for a battery screen printing machine. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an automatic feeding device for a battery screen printing machine, which solves the problem that existing flipping mechanisms usually do not have a limiting mechanism, which can easily cause the battery position to shift during the battery flipping process, thus affecting the printing effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automatic feeding device for a battery screen printing machine includes a worktable. A first feeding platform and a second feeding platform are respectively arranged on the left and right sides of the top of the worktable. A first tilting block and a second tilting block are symmetrically arranged on the top of the worktable. The first tilting block and the second tilting block are located inside the first feeding platform and the second feeding platform, respectively. An adsorption mechanism is embedded in the first tilting block and the second tilting block. The first tilting block and the second tilting block include a drive shaft. Multiple sets of tilting rods are axially symmetrically connected to the outside of the drive shaft. The adsorption mechanism includes an air extraction pipe located inside the tilting rod. An adsorption block is snapped into the tilting rod. An air supply pipe is arranged between the air extraction pipe and the adsorption block. A suction cup is arranged inside the adsorption block. A drive mechanism is arranged inside the worktable to cooperate with the drive shaft.

[0006] Preferably, the aforementioned drive mechanism includes a motor, which is fixed to the top of the workbench by a fixing block. A transmission wheel is coaxially fixedly connected to the output end of the motor, and a synchronous belt is sleeved between the transmission shaft and the transmission wheel.

[0007] Preferably, a third feeding platform is provided at the middle position of the top of the aforementioned workbench, a printing mechanism is provided on one side of the top of the workbench, a lifting block is provided on one side of the printing mechanism, a printing plate is provided at the bottom of the lifting block, and a screen mesh cloth for use with the printing plate is provided on the top of the workbench above the third feeding platform.

[0009] Preferably, the aforementioned first, second, and third conveying platforms are composed of a drive motor and multiple sets of rollers, and the top of the worktable is provided with a slot for use with the turning rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses an air supply pipe to create negative pressure on the suction cups inside the adsorption block, thus adsorbing and fixing the battery on one side. Simultaneously, the motor of the drive mechanism is securely installed via a fixing block, and its output drive wheel drives the drive shaft to rotate via a synchronous belt. Multiple sets of flipping rods on the outside of the drive shaft rotate with it in the slots on the top of the worktable.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-5 As shown, an automatic feeding device for a battery screen printing machine according to the present invention includes a worktable 1. A first feeding platform 2 and a second feeding platform 3 are respectively arranged on the left and right sides of the top of the worktable 1. A first flipping block 4 and a second flipping block 19 are symmetrically arranged on the top of the worktable 1. The first flipping block 4 and the second flipping block 19 are respectively located inside the first feeding platform 2 and the second feeding platform 3. An adsorption mechanism is embedded in the first flipping block 4 and the second flipping block 19.

[0020] The first turning block 4 and the second turning block 19 include a drive shaft 13. Multiple sets of turning rods 14 are axially symmetrically connected to the outside of the drive shaft 13. The adsorption mechanism includes an air extraction pipe 15, which is located inside the turning rods 14. An adsorption block 17 is snapped into the turning rod 14. An air supply pipe 16 is provided between the air extraction pipe 15 and the adsorption block 17. A suction cup 18 is provided inside the adsorption block 17. A drive mechanism is provided in the workbench 1 to cooperate with the drive shaft 13.

[0021] The battery is conveyed to the top of the workbench 1 via the first conveying platform 2 and reaches the position corresponding to the first flipping block 4. The adsorption mechanism inside the first flipping block 4 is activated. The suction pipe 15 generates negative pressure on the suction cup 18 inside the adsorption block 17 through the air supply pipe 16, adsorbing and fixing one side of the battery. The drive mechanism drives the transmission shaft 13 to rotate, and the multiple sets of flipping rods 14 axially symmetrically connected to the outside of the transmission shaft 13 rotate accordingly. Since the battery is adsorbed and fixed inside the flipping rod 14 by the suction cup 18, the battery flips together with the flipping rod 14 to complete the flipping action. After the flipping is completed, the adsorption mechanism stops working, the suction cup 18 releases the battery, and the battery is conveyed to the second conveying platform 3. When the battery needs to be flipped again, the second flipping block 19 works in the same way. After adsorbing and fixing the battery through its internal adsorption mechanism, the drive mechanism drives the flipping rod 14 to rotate to complete the flipping. After that, the battery continues to be conveyed to the subsequent process by the second conveying platform 3.

[0022] The drive mechanism includes a motor 12, which is fixed to the top of the workbench 1 by a fixing block. A transmission wheel is coaxially fixed to the output end of the motor 12. A synchronous belt is sleeved between the transmission shaft 13 and the transmission wheel. A third feeding platform 5 is set at the middle of the top of the workbench 1. A printing mechanism 6 is set on one side of the top of the workbench 1. A lifting block 7 is set on one side of the printing mechanism 6. A printing plate 8 is set at the bottom of the lifting block 7. A screen mesh 9 for use with the printing plate 8 is set on the top of the workbench 1 above the third feeding platform 5.

[0023] The battery is conveyed to the worktable 1 via the first conveyor 2. After reaching the position of the first flipping block 4, the adsorption mechanism is activated, and the suction cup 18 adsorbs the battery under negative pressure. At this time, the motor 12 is fixed to the top of the worktable 1 by a fixing block, and the transmission wheel at its output end drives the transmission shaft 13 to rotate via a synchronous belt. The flipping rod 14 rotates with the transmission shaft 13, completing the initial flipping of the battery (e.g., with the printed side facing up). During the flipping process, the adsorption mechanism continuously fixes the battery to prevent positional displacement. After the initial flipping, the suction cup 18 releases the battery, which is then transferred to the third conveyor 5, where it is precisely conveyed to the printing unit below the printing mechanism 6. At the workstation, directly below the screen mesh 9, the printing mechanism 6 is activated. The lifting block 7 lowers the bottom printing plate 8, causing the printing plate 8 to adhere to the screen mesh 9. The ink is printed onto the battery surface through the perforated pattern area of ​​the screen mesh 9. After printing is completed, the lifting block 7 raises the printing plate 8 to reset. The printed battery is then transported to the second flipping block 19 via the third conveyor 5. The adsorption mechanism of the second flipping block 19 is activated to fix the battery. The motor 12 drives the transmission shaft 13 to rotate via the synchronous belt, completing the second flipping and restoring the initial state. Subsequently, the battery is transported to the next process by the second conveyor 3.

[0024] A baking block 10 is provided on one side of the wire mesh cloth 9 at the top of the workbench 1. The first feeding table 2, the second feeding table 3 and the third feeding table 5 are composed of a drive motor and multiple sets of rollers. A slot 11 is provided on the top of the workbench 1 to cooperate with the turning rod 14.

[0025] The battery is conveyed from the first conveying platform 2 to the worktable 1. When it reaches the position of the first flipping block 4, the adsorption mechanism is activated, and the suction cup 18 adsorbs the battery under negative pressure. The motor 12 is fixed by the fixing block, and the transmission wheel at its output end drives the transmission shaft 13 to rotate via the synchronous belt. The flipping rod 14 rotates with the transmission shaft 13 in the slot 11 at the top of the worktable 1, performing the initial flipping of the battery. During the process, the adsorption mechanism continuously fixes the battery. After the initial flipping, the suction cup 18 releases the battery, and the battery is transferred to the third conveying platform 5. Driven by the roller, it is accurately conveyed to the printing station below the printing mechanism 6, that is, directly below the screen mesh 9. The printing mechanism 6 is activated, and the lifting block 7 drives the printing plate 8 to descend and fit against the screen mesh 9. The paste passes through... The mesh screen is printed onto the battery surface. After printing, the lifting block 7 drives the printing plate 8 to rise and reset. The printed battery is then transported by the third conveying platform 5 to the baking block 10 on one side of the screen mesh 9. The baking block 10 bakes and cures the paste on the battery surface to ensure rapid curing. The cured battery is then transported by the third conveying platform 5 to the second flipping block 19. The adsorption mechanism of the second flipping block 19 is activated to fix the battery. The motor 12 drives the transmission shaft 13 to rotate through the synchronous belt. The flipping rod 14 rotates in the slot 11 to complete the second flipping. The battery is then transferred to the second conveying platform 3. Driven by the rollers of the second conveying platform 3, the battery is transported to subsequent testing, packaging and other processes.

[0026] To better illustrate this utility model, its working principle is explained in detail below:

[0027] First, the battery is transported by the first conveying platform 2 to the corresponding position of the first flipping block 4 on the top of the workbench 1. At this time, the adsorption mechanism inside the first flipping block 4 is activated: the air extraction pipe 15 generates negative pressure on the suction cup 18 inside the adsorption block 17 through the air supply pipe 16, which adsorbs and fixes one side of the battery. At the same time, the motor 12 of the drive mechanism is firmly installed by the fixing block, and its output end transmission wheel drives the transmission shaft 13 to rotate through the synchronous belt. Multiple sets of flipping rods 14 on the outside of the transmission shaft 13 rotate with it in the slot 11 on the top of the workbench 1. The battery is fixed inside the flipping rod 14 by the suction cup 18 and flips synchronously, completing the initial flipping and making the printed side face up. In this process, the negative pressure fixation of the adsorption mechanism can counteract the inertial force during flipping, solving the problem of battery floating and position displacement in traditional flipping mechanisms. The slot 11 provides a dedicated rotation space for the flipping rod 14, avoiding collision and wear with the workbench 1 and extending the equipment life.

[0028] Secondly, after the initial flip, the suction cup 18 releases the battery, which is then transferred to the third feeding table 5. The rigid transmission of the roller ensures that the battery is accurately delivered to the screen 9 below the printing mechanism 6. Subsequently, the lifting block 7 of the printing mechanism 6 drives the printing plate 8 to descend and fit against the screen 9. The ink is printed onto the surface of the battery through the perforated area of ​​the screen. After printing is completed, the lifting block 7 drives the printing plate 8 to reset, reducing battery slippage and offset. Combined with the bonding accuracy between the printing plate 8 and the screen, the printing quality is improved.

[0029] The baking block 10 on one side of the screen mesh 9 on the top of the worktable 1 can bake and solidify the paste on the surface of the battery immediately after printing, so as to prevent the paste from falling off and deforming due to friction and collision during subsequent transportation, thus ensuring the integrity of the pattern. The speed of the motor 12 is adjustable, which can adapt to the transportation needs of batteries of different specifications. The slot 11 on which the flipping rod 14 relies for rotation not only plays a guiding role, but also reduces the friction between the flipping rod 14 and the worktable 1, ensuring rotation accuracy and indirectly improving the consistency of the battery position after flipping.

[0030] Finally, the printed and baked batteries are sent from the third conveyor 5 to the second flipping block 19. The second flipping block 19 completes the second flipping in the same way as the first flipping block 4, restoring the initial state. The fixation of the adsorption mechanism ensures that the flipping process is equally accurate. Then the batteries are transferred to the second conveyor 3 and transported to subsequent processes such as testing and packaging.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
