Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, and in particular to a perovskite battery coating device. Background Technology

[0002] As a next-generation photovoltaic technology, the uniformity of the coating and the quality of the core light-absorbing layer of perovskite solar cells directly affect the photoelectric conversion efficiency of the cells. Existing coating equipment requires a corresponding material-fixing mechanism to secure the cells during fixed-position production, thereby preventing cell movement during the coating process.

[0003] However, traditional devices often rely on manually adjusting bolts or using mechanical clamps to fix the conductive substrate, which involves cumbersome operation steps and makes it difficult to achieve rapid and accurate positioning, thus affecting the improvement of production efficiency. To address this, this solution proposes a perovskite battery coating device. Utility Model Content

[0004] This invention proposes a perovskite battery coating device, which solves the problem of inconvenience in quickly positioning and clamping batteries during the production process of existing battery coating devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A perovskite solar cell coating apparatus includes a processing table and a coating machine mounted on the top surface of the processing table, wherein a material holding mechanism is mounted on the top surface of the processing table.

[0007] The material holding mechanism includes a mounting plate rotatably connected to the top surface of the processing table, multiple placement plates fixed to the outer periphery of the mounting plate, a clamping assembly mounted on the placement plates for clamping the battery, and an adjustment assembly for driving the clamping assembly to open and close.

[0008] The clamping assembly includes multiple clamping plates mounted on the top surface of the placement plate, a support plate fixed on the top surface of the placement plate, and a transmission component for driving the clamping plates to move radially along the support plate. The multiple clamping plates form a clamping space for clamping the battery.

[0009] The adjustment assembly is installed on the bottom surface of the placement plate and is used to adjust the simultaneous movement of multiple clamping plates to adjust the size of the clamping space.

[0010] The above technical solution not only facilitates battery positioning and clamping, but also enables uninterrupted loading and unloading operations through the setting of multiple placement plates, which not only reduces the difficulty of operation, but also greatly improves production efficiency.

[0011] As a further improvement to the above solution, the top surface of the placement plate is provided with a plurality of mounting slots for mounting transmission components. The mounting slots are arranged along the radial direction of the support plate. The transmission components include a screw rotatably connected in the mounting slot and a transmission gear sleeved on the outer circumference of the screw. The bottom of the clamping plate extends into the mounting slot and is threadedly sleeved on the outer circumference of the screw. The bottom of the transmission gear extends to the bottom of the placement plate.

[0012] As a further improvement to the above solution, the adjustment assembly includes a geared disc rotatably connected to the bottom surface of the placement plate and meshing with multiple transmission gears, a drive gear fixed to the bottom surface of the geared disc, and a rack mounted on the bottom surface of the placement plate via an elastic element, the rack meshing with the drive gear.

[0013] As a further improvement to the above solution, the elastic element includes a fixed sleeve that is movably sleeved on the outer periphery of the rack and fixedly connected to the bottom surface of the placement plate, a spring clip sleeved on the outer periphery of the rack, and a spring connected between the spring clip and the fixed sleeve. An adjusting column is fixed on the top surface of the rack, and an adjusting groove is provided on the top surface of the placement plate for the adjusting column to move. The top of the adjusting column passes through the adjusting groove and extends above the placement plate.

[0014] As a further improvement to the above solution, the top surface of the processing table is provided with a receiving groove located directly below the coating machine, and a receiving plate is provided in the receiving groove. The front of the processing table is provided with a connecting groove for the receiving plate to enter and exit, and one end of the receiving plate extends through the connecting groove to the outside of the processing table.

[0015] As a further improvement to the above solution, a limiting plate with a length greater than the length of the connecting groove is fixed at one end of the receiving plate located outside the processing table, and a pull ring is fixed on the front of the limiting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up the material fixing mechanism, not only can multiple placement plates be used to achieve high-efficiency coating, but the cooperation between the clamping component and the adjustment component also makes it convenient for workers to quickly clamp the battery before coating and to quickly release the clamped battery after coating, thereby reducing the difficulty of operation and helping to improve production efficiency.

[0018] 2. By setting up the receiving plate and receiving trough, not only can the raw material be prevented from dripping onto the workbench surface during coating, but it also facilitates the subsequent processing of the raw material that drips onto the receiving plate.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1:

[0030] Please combine Figures 1-6 This embodiment includes a processing table 1 and a coating machine 5 installed on the top surface of the processing table 1. A PLC control panel 3 connected to the coating machine 5 is installed on the front of the processing table 1. The coating machine 5 is controlled through the PLC control panel 3 to complete the coating of the battery.

[0031] A material holding mechanism 2 is installed on the top surface of the processing table 1. The material holding mechanism 2 includes a mounting plate 205 rotatably connected to the top surface of the processing table 1, multiple placement plates 201 fixed to the outer periphery of the mounting plate 205, a clamping assembly for holding the battery mounted on the placement plates 201, and an adjusting assembly for driving the opening and closing of the clamping assembly. A support shaft rotatably connected to the top surface of the processing table 1 is fixed at the center of the bottom surface of the mounting plate 205. A servo motor for driving the rotation of the support shaft is installed inside the processing table 1. The output shaft of the servo motor is connected to the support shaft. The servo motor is connected to a PLC control panel 3. The start and stop of the servo motor can be controlled through the PLC control panel 3. During coating, the battery is placed... The battery is clamped on the top surface of the placement plate 201 using a clamping assembly. Then, the servo motor rotates, driving the mounting plate 205 to rotate, which in turn drives multiple placement plates 201 to rotate, thereby feeding the battery sequentially under the coating machine 5 for coating. Each time a placement plate 201 rotates to the direct under of the coating machine 5, the servo motor stops intermittently, allowing time for the coating machine 5 to work. After the coating is completed, the servo motor rotates again, thus rotating the next battery to be processed under the coating machine 5. The processed battery can be removed from the placement plate 5 after leaving the area under the coating machine 5, and then a new battery to be processed can be placed on it. This cycle is repeated to achieve efficient battery processing.

[0032] The clamping assembly includes multiple clamping plates 203 mounted on the top surface of the placement plate 201, a support plate 202 fixed to the top surface of the placement plate 201, and a transmission component for driving the clamping plates 203 to move radially along the support plate 202. The multiple clamping plates 203 form a clamping space for clamping the battery. The support plate 202 is located at the center of the multiple clamping plates 203. The top surface of the placement plate 201 has multiple mounting slots 207 for mounting the transmission component. The mounting slots 207 are arranged radially along the support plate 202. The transmission component includes a screw 206 rotatably connected in the mounting slot 207 and a sleeve on the screw 206. The transmission gear 209 on the outer periphery of the screw 206 extends into the mounting groove 207 and is threaded onto the outer periphery of the screw 206. The bottom of the transmission gear 209 extends below the placement plate 201. When fixing the material, the battery to be processed is placed on the support plate 202. After the screw 206 rotates forward, the support plate 203 moves closer to the support plate 202, and the clamping space becomes smaller until the support plate 203 abuts against the edge of the battery, thereby completing the clamping and fixing of the battery. Conversely, when the screw 206 rotates backward, the support plate 203 moves away from the support plate 202, and the clamping space becomes larger, thereby releasing the battery.

[0033] An adjustment assembly is installed on the bottom surface of the placement plate 201 and is used to adjust the simultaneous movement of multiple clamping plates 203 to adjust the clamping space. The adjustment assembly includes a geared disc 210 rotatably connected to the bottom surface of the placement plate 201 and meshing with multiple transmission gears 209, a drive gear 211 fixed to the bottom surface of the geared disc 210, and a rack 212 mounted on the bottom surface of the placement plate 201 via an elastic element. The rack 212 meshes with the drive gear 211, which is coaxially arranged with the geared disc 210. When the rack 212 moves, it drives the drive gear 211 to rotate, which in turn drives the geared disc 210 to rotate. The rotation of the geared disc 210 then drives the multiple transmission gears 209 to rotate, thereby achieving the purpose of driving multiple screws 206 to rotate synchronously. The elastic element is provided so that it can be adjusted by the gears. After the rack 212 loses external force, it automatically returns to its original position. When clamping the battery, it drives the rack 212 to move closer to the mounting plate 205, thereby driving the drive gear 211 to rotate forward. This causes multiple clamping plates 203 to move away from the support plate 202, increasing the clamping space. The battery is then placed on the support plate 202. After releasing the rack 212, under the action of the elastic element, the rack 212 automatically returns to its original position and moves away from the mounting plate 205, thereby driving the drive gear 211 to rotate in reverse. The clamping plates 203 move closer to the support plate 202. After the clamping plates 203 contact the edge of the battery, they push the battery to move until all the clamping plates 203 are in contact with the edge of the battery, thus clamping the battery. This achieves the purpose of convenient positioning and clamping of the battery.

[0034] In this embodiment, the elastic element includes a fixed sleeve 214 movably sleeved on the outer periphery of the rack 212 and fixedly connected to the bottom surface of the placement plate 201, a spring catch 213 sleeved on the outer periphery of the rack 212, and a spring connecting the spring catch 213 and the fixed sleeve 214. An adjusting post 204 is fixed on the top surface of the rack 212, and an adjusting groove 208 is provided on the top surface of the placement plate 201 for the adjusting post 204 to move. The top of the adjusting post 204 passes through the adjusting groove 208 and extends above the placement plate 201. The adjusting post 204 is conveniently positioned and drives the rack 212 to move, thereby adjusting the size of the clamping space and fixing the battery. First, increase the clamping space. Then, move the adjusting column 204 towards the side closer to the mounting plate 205, which in turn moves the rack 212 closer to the mounting plate 205. The spring is then compressed. After the battery is placed on top of the tray 202, release the adjusting column 204. The spring then returns to its original length and moves the rack 212 away from the mounting plate 205, which reduces the clamping space and eventually clamps the battery automatically. Similarly, when removing the processed battery, move the adjusting column 204 towards the side closer to the mounting plate 205 to increase the clamping space, and then the battery can be easily removed from the tray 202.

[0035] In this embodiment, the coating machine 5 is an automatic coating machine in the prior art.

[0036] Example 2:

[0037] Combination Figure 1 and Figure 6 This embodiment is an improvement on embodiment 1, in that: a receiving groove 6 is provided on the top surface of the processing table 1, located directly below the coating machine 5, and a receiving plate 8 is provided in the receiving groove 6. A connecting groove for the receiving plate 8 to enter and exit is provided on the front of the processing table 1. One end of the receiving plate 8 extends through the connecting groove to the outside of the processing table 1. The raw material dripping during coating will fall on the top surface of the receiving plate 8. Afterwards, when cleaning, the receiving plate 8 can be easily cleaned by simply pulling it out of the processing table 1, thereby avoiding the raw material dripping onto the top surface of the processing table 1 and avoiding the problem of cleaning the processing table 1 afterwards.

[0038] In this embodiment, a limiting plate 4 with a length greater than the length of the connecting groove is fixed at one end of the receiving plate 8 located outside the processing table 1. A pull ring 7 is fixed on the front of the limiting plate 4. The limiting plate 4 can limit the length of the receiving plate 8 inserted into the receiving groove 6, while the pull ring 7 is provided to facilitate the removal of the receiving plate 8 from the receiving groove 6.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
