[0003] Traditional surface etching devices require clamping and fixing several solar cell materials when they are immersed in an etching solution, which is often cumbersome. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The purpose of this invention is to provide a surface etching device for processing solid solar cell materials, in order to solve the problem that existing etching devices are cumbersome when clamping solar cell materials. (II) Utility Model Content
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a surface etching device for processing solid solar cell materials, comprising a main frame, an etching tank, and a hydraulic lifting assembly. The top of the main frame is provided with an etching tank, an isolation frame is fixedly connected to the outer side of the top of the main frame, a hydraulic lifting assembly is fixedly connected to the top inside the isolation frame, a drying structure is fixedly connected to one side of the isolation frame, buffer protection structures are provided on both sides of the top of the etching tank, a material carrier plate is fixedly connected to the bottom of the hydraulic lifting assembly, and a clamping structure is provided inside the material carrier plate.
[0008] Preferably, the drying structure includes an exhaust pipe, an activated carbon layer, and an exhaust fan. The exhaust pipe is disposed on one side of the isolation frame, and an activated carbon layer is fixedly connected to one side inside the exhaust pipe. An exhaust fan is disposed on the inner side of the exhaust pipe.
[0009] Preferably, the exhaust pipe and the interior of the exhaust fan are on the same horizontal plane, and the exhaust pipe and the interior of the isolation frame are perpendicular to each other, so that the air flowing inside the isolation frame can blow towards the clamped solar cell material.
[0010] Preferably, the buffer protection structure includes a spring tube, a buffer spring, a push rod, and a slot. The spring tube is disposed at the bottom end of both sides of the etching tank. A buffer spring is fixedly connected to the bottom end inside the spring tube. A push rod is fixedly connected to the top end of the buffer spring. Slots are provided inside both sides of the bottom end of the carrier plate.
[0011] Preferably, the spring tube and the inside of the push rod have a sliding structure, and the push rod and the inside of the slot are on the same vertical plane, so that the push rod can be inserted into the inside of the slot.
[0012] Preferably, the clamping structure includes a slide groove, a compression spring, a slider, and a clamping block. The slide groove is disposed inside the material carrier plate. A compression spring is fixedly connected to one side of the slide groove. A slider is fixedly connected to one side of the compression spring. A clamping block is fixedly connected to the bottom end of the slider.
[0013] Preferably, the groove is symmetrically arranged about the vertical center line of the carrier plate, and there is a sliding structure between the groove and the inside of the slider, so that the clamping block can clamp the solar cell material.
[0014] (III) Beneficial Effects
[0015] The present invention provides a surface etching device for processing solid solar cell materials, which has the following advantages: by setting a clamping structure, the solar cell material is inserted along the symmetrical distribution of the clamping blocks due to the symmetrical distribution of the clamping blocks. The clamping blocks are slowly pushed apart to both ends by the sliding structure of the sliding groove and the slider, and the clamping blocks are always stably clamped to both ends of the inserted solar cell material under the action of the compression spring, thus realizing convenient clamping of solar cell materials.
[0016] By incorporating a drying structure and activating the exhaust fans on both sides, the exhaust fans quickly draw air from inside the isolation frame, thereby increasing airflow within the frame and allowing the suspended solar cell material to dry rapidly under the airflow. The airflow is filtered by the activated carbon layer to prevent harmful gases from evaporating, thus achieving rapid drying of the solar cell material.
[0017] With the addition of a buffer protection structure, as the carrier plate moves, its bottom end gradually comes into contact with the top of the etching tank. During this process, the push rod first inserts into the slot as the carrier plate falls. As the carrier plate continues to descend, the push rod gradually presses against the buffer spring. At this time, the buffer spring, under its own elastic force, causes the push rod to generate a reverse thrust against the falling carrier plate and buffer it, thus achieving buffer protection for the carrier plate.

[0029] Example 1
[0030] Please see Figure 1-7 This utility model provides a surface etching device for processing solid solar cell materials, including a main frame 1, an etching groove 2, and a hydraulic lifting assembly 4. The top of the main frame 1 is provided with the etching groove 2. An isolation frame 3 is fixedly connected to the outer side of the top of the main frame 1. The top of the isolation frame 3 is fixedly connected to the hydraulic lifting assembly 4. The bottom of the hydraulic lifting assembly 4 is fixedly connected to the material plate 6. The material plate 6 is provided with a clamping structure 8. The clamping structure 8 includes a slide groove 801, a compression spring 802, a slider 803, and a clamping block 804. The slide groove 801 is provided inside the material plate 6. A compression spring 802 is fixedly connected to one side of the slide groove 801. A slider 803 is fixedly connected to one side of the compression spring 802. The bottom of the slider 803 is fixedly connected to the clamping block 804. The slide groove 801 is symmetrical about the vertical center line of the material plate 6. The slide groove 801 and the slider 803 have a sliding structure.
[0031] The working principle of the surface etching device for solid solar cell material processing based on Embodiment 1 is as follows: When using the device, the surface of the solar cell material is pre-coated with an etching agent, and then it is sequentially installed below the carrier plate 6. Due to the symmetrical distribution of the clamping blocks 804, the solar cell material is inserted symmetrically along the clamping blocks 804. Under the sliding structure of the slide groove 801 and the slider 803, the symmetrical clamping blocks 804 are slowly pushed open to both ends. Under the action of the compression spring 802, the clamping blocks 804 are always clamped to both ends of the inserted solar cell material, making the clamping and installation of the solar cell material more convenient. Then, several solar cell materials are installed in sequence, and the device can be used after installation.
[0032] Example 2
[0033] This embodiment also includes: a drying structure 5 is fixedly connected to one side of the isolation frame 3. The drying structure 5 includes an exhaust pipe 501, an activated carbon layer 502 and an exhaust fan 503. The exhaust pipe 501 is located on one side of the isolation frame 3. An activated carbon layer 502 is fixedly connected to one side of the inside of the exhaust pipe 501. An exhaust fan 503 is located inside the exhaust pipe 501. The exhaust pipe 501 and the exhaust fan 503 are on the same horizontal plane. The exhaust pipe 501 and the inside of the isolation frame 3 are perpendicular to each other.
[0034] In this embodiment, when the device is in use, the hydraulic lifting component 4 causes the carrier plate 6 to carry each solar cell material into the interior of the etching tank 2. After the etching tank 2 is etched, the carrier plate 6 will be lifted by the hydraulic lifting component 4. At this time, the surface of the solar cell material will be covered with a large amount of etching solution. At this time, the exhaust fans 503 on both sides are started, so that the exhaust fans 503 quickly draw out the air inside the isolation frame 3, so that the air flow inside the isolation frame 3 can be improved, and the suspended solar cell material can be dried quickly under the air flow. The flowing air is filtered by the activated carbon layer 502 to prevent harmful gases from volatilizing outward.
[0035] Example 3
[0036] This embodiment also includes: buffer protection structures 7 are provided on both sides of the top of the etching tank 2. The buffer protection structure 7 includes a spring tube 701, a buffer spring 702, a push rod 703 and a slot 704. The spring tube 701 is provided at the bottom of both sides of the etching tank 2. The bottom of the spring tube 701 is fixedly connected to the buffer spring 702. The top of the buffer spring 702 is fixedly connected to the push rod 703. The slots 704 are provided inside both sides of the bottom of the material plate 6. The spring tube 701 and the push rod 703 have a sliding structure. The push rod 703 and the slot 704 are in the same vertical plane.
[0037] In this embodiment, when the hydraulic lifting assembly 4 drives the carrier plate 6 to move each solar cell material downwards towards the top of the etching tank 2, as the carrier plate 6 moves continuously, its bottom end gradually contacts the top of the etching tank 2. During this process, the push rod 703 first inserts into the slot 704 as the carrier plate 6 falls. As the carrier plate 6 continues to fall, the push rod 703 gradually presses against the buffer spring 702. At this time, the buffer spring 702, under its own elastic force, causes the push rod 703 to generate a reverse thrust on the falling carrier plate 6 and buffer it.
