Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a protective device and a texturing device. Background Art

[0002] The texturing process is an important step in the preparation of solar cells. During texturing, a basket loaded with silicon wafers is placed in a texturing tank containing corrosive liquids such as acid or alkali to form a velvet surface on the surface of the silicon wafers.

[0003] However, when the flower baskets are transferred between the various texturing tanks, the residual corrosive liquid on the flower baskets will drip onto the tank covers, where they will form alkaline salt crystals. These alkaline salt crystals will accumulate over time and corrode the tank covers. Therefore, the machine must be regularly shut down for cleaning or replacement of the tank covers, which increases costs and affects production efficiency. Furthermore, the alkaline salt crystals are difficult to remove, and if not removed properly, they can easily fall into the texturing tanks, causing changes in the solution within the tanks and affecting the texturing effect.

DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0025] See Figure 1 and Figure 3 The present invention provides a texturing apparatus according to one embodiment, comprising a texturing tank and a material handling device 10. The material handling device 10 includes a gripping mechanism 12 for gripping a flower basket. During texturing, the gripping mechanism 12 grips the flower basket within the texturing tank, lifts the flower basket upward, and places the flower basket within the texturing tank.

[0026] Optionally, the material retrieving device 10 is a material retrieving robot. The material retrieving robot further includes a mechanical arm 11, and the gripping mechanism 12 is mounted on the mechanical arm 11. Of course, in other embodiments, the material retrieving device 10 can also be a three-axis moving device, which is not limited to this.

[0027] During the transfer of the flower basket, the residual solution on the flower basket will drip onto the slot cover of the texturing tank body and form alkaline salt crystals on the slot cover. After a long period of accumulation, the alkaline salt crystals will corrode the slot cover. Therefore, it is necessary to regularly shut down the machine to clean or replace the slot cover, which increases costs and affects production efficiency. In addition, the alkaline salt crystals are difficult to clean. Alkaline salt crystals that are not cleaned up will fall into the texturing tank body, causing the solution in the texturing tank body to change, affecting the texturing effect. In order to solve this problem, the present application proposes a protective device 20.

[0028] In one embodiment, see Figure 1 and Figure 3 The protective device 20 includes a protective shell 21 and a drive mechanism 22. The protective shell 21 is mounted on the material retrieving device 10. The drive mechanism 22 is connected to the protective shell 21 and is used to drive the protective shell 21 to operate, so that the protective shell 21 has an open state exposing the gripping mechanism 12 and a closed state covering the gripping mechanism 12.

[0029] During use, the protective device 20 is installed at the position of the material taking device 10 corresponding to the grabbing mechanism 12. When the grabbing mechanism 12 needs to grab the flower basket in the velvet making tank body, the driving mechanism 22 drives the protective shell 21 to open to expose the grabbing mechanism 12, so that the grabbing mechanism 12 can grab the flower basket in the velvet making tank body. After the grabbing mechanism 12 grabs the flower basket and is suspended in the air and is to be moved, the driving mechanism 22 drives the protective shell 21 to close, so that the protective shell 21 covers the grabbing mechanism 12 and the flower basket, so that the solution on the flower basket drips onto the protective shell 21, and the protective shell 21 blocks the solution, thereby preventing the solution on the flower basket from dripping onto the tank cover of the velvet making tank body, reducing the replacement cycle of the tank cover, reducing costs, and at the same time reducing the number of shutdowns and improving production efficiency.

[0030] In one embodiment, see Figure 1 and Figure 3 The protective shell 21 includes a first shell 211 having an opening and a second shell 212. The first shell 211 includes a first side 2111 and a second side 2112, and the first side 2111 is rotatably mounted on the retrieving device 10. The second shell 212 includes a third side 2121 and a fourth side 2122, and the third side 2121 is rotatably mounted on the retrieving device 10. Optionally, the first side 2111 and the third side 2121 are rotatably mounted on opposite sides of the robotic arm 11.

[0031] Further, see Figure 1 The driving mechanism 22 is connected to the first shell 211 and the second shell 212, and the driving mechanism 22 is used to drive the first shell 211 and the second shell 212 to flip over. In the closed state, the second side 2112 is docked with the fourth side 2122. In the open state, the second side 2112 is separated from the fourth side 2122. When the grabbing mechanism 12 needs to grab the flower basket in the velvet making tank body, the driving mechanism 22 drives the first shell 211 and the second shell 212 to flip over, so that the second side 2112 is separated from the fourth side 2122, so that the protective shell 21 opens to expose the grabbing mechanism 12, and the grabbing mechanism 12 can grab the flower basket in the velvet making tank body. When the grabbing mechanism 12 grabs the flower basket and is suspended in the air and is about to leave, the driving mechanism 22 drives the first shell 211 and the second shell 212 to flip in the opposite direction, so that the second side 2112 of the first shell 211 is docked with the fourth side 2122 of the second shell 212, so that the protective shell 21 is closed. The closed protective shell 21 covers the grabbing mechanism 12 and the flower basket to prevent the solution on the flower basket from dripping onto the slot cover of the texturing slot body, reducing the replacement cycle of the slot cover, and at the same time reducing the number of shutdowns and improving production efficiency.

[0032] In one embodiment, see Figure 1 and Figure 2The second side 2112 is provided with a first groove 2113, extending along the length of the second side 2112. The fourth side 2122 is provided with a second groove 2123, extending along the length of the fourth side 2122. In the closed state, the first groove 2113 and the second groove 2123 enclose a liquid reservoir 213. When the protective shell 21 is in the closed state, solution dripping from the flower basket onto the protective shell 21 flows into the protective shell 21 and is stored in the liquid reservoir 213, preventing the solution dripping onto the protective shell 21 from flowing freely and overflowing.

[0033] Optionally, see Figure 2 The cross-sectional shape of the first groove 2113 is an arc, and the cross-sectional shape of the second groove 2123 is an arc. In the closed state, the cross-sectional shape of the liquid storage tank 213 formed by the first groove 2113 and the second groove 2123 is a semicircular shape. Of course, in other embodiments, the cross-sectional shape of the first groove 2113 and the second groove 2123 can also be triangular, etc., and is not limited to this.

[0034] In one embodiment, see Figure 1 and Figure 3 The bottom of the first housing 211 is provided with a first sloped portion 2114. The first sloped portion 2114 slopes from the side of the bottom of the first housing 211 away from the second side 2112 to the second side 2112 in a direction away from the first side 2111. Thus, when the solution from the flower basket drips onto the bottom of the first housing 211, the first sloped portion 2114 guides the solution, allowing it to flow quickly into the liquid reservoir 213.

[0035] Further, see Figure 1 and Figure 3 The bottom of the second housing 212 is provided with a second inclined surface 2124. The second inclined surface 2124 slopes from the side of the bottom of the second housing 212 away from the fourth side 2122 to the fourth side 2122 in a direction away from the third side 2121. Thus, when the solution from the flower basket drips onto the bottom of the second housing 212, the second inclined surface 2124 guides the solution, allowing it to flow quickly into the liquid reservoir 213.

[0036] It can be understood that the first inclined portion 2114 is inclined downward from the bottom of the first shell 211 away from the second side 2112 to the second side 2112, and the second inclined portion 2124 is inclined downward from the bottom of the second shell 212 away from the fourth side 2122 to the fourth side 2122, so that the bottom of the protective shell 21 is higher on both sides and lower in the middle when it is closed.

[0037] In one embodiment, see Figure 1 and Figure 3The protective device 20 further includes a drain pipe 23, which is connected to the liquid storage tank 213. When the solution dripping onto the protective shell 21 flows into the liquid storage tank 213, the solution in the liquid storage tank 213 is discharged through the drain pipe 23. In this way, the solution in the liquid storage tank 213 can be discharged in time through the drain pipe 23, preventing the solution in the liquid storage tank 213 from dripping onto the tank cover of the texturing tank body when the protective shell 21 is opened.

[0038] Optionally, the sewage pipe 23 is a hose, which has good flexibility, bending resistance, and tensile strength, making it convenient for the sewage pipe 23 to move with the grabbing mechanism 12 .

[0039] Further, see Figure 1 The protective device 20 further includes a liquid storage container 24, and one end of the drain pipe 23 away from the liquid storage tank 213 is connected to the liquid storage container 24. In this way, the solution in the liquid storage tank 213 can be discharged into the liquid storage container 24 through the drain pipe 23 for storage, so that the solution can be centrally processed.

[0040] In one embodiment, see Figure 1 and Figure 3 The protective device 20 further includes a slide 25. The slide 25 is provided with a chute 251. The end of the drain pipe 23 facing away from the liquid storage tank 213 is movably disposed in the chute 251. The chute 251 is in communication with the liquid storage container 24 and the drain pipe 23. Since the liquid storage container 24 is fixed, while the drain pipe 23 moves with the robotic arm 11, the slide 25 is provided in this embodiment. The end of the drain pipe 23 facing away from the liquid storage tank 213 is movably disposed in the chute 251. In this way, the drain pipe 23 can move with the robotic arm 11, ensuring that the solution in the liquid storage tank 213 can be smoothly discharged into the chute 251, and then flow from the chute 251 into the liquid storage container 24.

[0041] Of course, in other embodiments, the slideway 25 is provided with a sliding member, the liquid storage container 24 is mounted on the sliding member, and the end of the sewage pipe 23 facing away from the liquid storage tank 213 is connected to the liquid storage container 24.

[0042] In one embodiment, see Figure 1 There is one liquid storage container 24, which is located at one end of the slideway 25 along its length. Alternatively, there are at least two liquid storage containers 24, which are located at both ends of the slideway 25 along its length. In this way, interference between the liquid storage container 24 and other components can be avoided.

[0043] Of course, in other embodiments, the liquid storage container 24 may also be disposed at any position along the length of the slide 25 , as long as the liquid storage container 24 is connected to the slide 25 .

[0044] In one embodiment, see Figure 1 and Figure 3The drive mechanism 22 includes a first drive assembly 221 and a second drive assembly 222. The first drive assembly 221 and the second drive assembly 222 are mounted on the robotic arm 11. The first drive assembly 221 is connected to the first housing 211 and is used to drive the first housing 211 to flip. The second drive assembly 222 is connected to the second housing 212 and is used to drive the second housing 212 to flip. In this way, the first housing 211 and the second housing 212 are driven by the first drive assembly 221 and the second drive assembly 222, respectively, which improves the flexibility of the drive.

[0045] Optionally, participate Figure 1 The first drive assembly 221 includes a first drive member 2211 and a first rotating shaft 2212. The first rotating shaft 2212 is rotatably mounted on one side of the robotic arm 11, and the first housing 211 is mounted on the first rotating shaft 2212. The first drive member 2211 is connected to the first rotating shaft 2212 and is used to drive the first rotating shaft 2212 to rotate about its own axis, thereby causing the first housing 211 to flip. The first drive member 2211 is a motor, etc.

[0046] Optionally, see Figure 1 The second drive assembly 222 includes a second drive member 2221 and a second rotating shaft 2222. The second rotating shaft 2222 is rotatably mounted on the other side of the robotic arm 11, and the second housing 212 is mounted on the second rotating shaft 2222. The second drive member 2221 is connected to the second rotating shaft 2222 and is used to drive the second rotating shaft 2222 to rotate about its own axis, thereby causing the second housing 212 to flip. The second drive member 2221 is a motor, etc.

[0047] In one embodiment, see Figure 3 and Figure 4 The robotic arm 11 is provided with a first guide portion 111, and the first guide portion 111 extends along the length direction of the robotic arm 11. The first guide portion 111 is provided with a first sliding member 112, and the first sliding member 112 is provided with a first mounting hole 1121, and the first rotating shaft 2212 is rotatably provided in the first mounting hole 1121. Optionally, a first bearing is provided on the first rotating shaft 2212, and the first bearing is provided in the first mounting hole 1121 and is connected and cooperated with the hole wall of the first mounting hole 1121. When in use, the first sliding member 112 can move on the first guide portion 111 to drive the first shell 211 to move, thereby adjusting the position of the first shell 211 relative to the grasping mechanism 12, so that the first shell 211 can better cover the grasping mechanism 12.

[0048] Optionally, see Figure 4The first guide portion 111 is a first guide groove, and the cross section of the first guide groove is T-shaped. The first sliding member 112 is T-shaped. This arrangement can prevent the first sliding member 112 from escaping from the first guide groove.

[0049] Furthermore, at least two first sliding members 112 are provided, and all first sliding members 112 are arranged along the extension direction of the first guide portion 111. In this way, the first rotating shaft 2212 is supported by at least two first sliding members 112, ensuring the stability of the installation of the first rotating shaft 2212.

[0050] In one embodiment, see Figure 3 The robotic arm 11 is provided with a second guide portion 113, and the second guide portion 113 extends along the length direction of the robotic arm 11. The second guide portion 113 is provided with a second sliding member 114, and the second sliding member 114 is provided with a second mounting hole 1141. The second rotating shaft 2222 is rotatably provided in the second mounting hole 1141. Optionally, a second bearing is provided on the second rotating shaft 2222, and the second bearing is provided in the second mounting hole 1141 and is connected and cooperated with the hole wall of the second mounting hole 1141. When in use, the second sliding member 114 can move on the second guide portion 113 to drive the second shell 212 to move, thereby adjusting the position of the second shell 212 relative to the grasping mechanism 12, so that the second shell 212 can better cover the grasping mechanism 12.

[0051] Optionally, see Figure 3 The second guide portion 113 is a second guide groove, and the cross section of the second guide groove is T-shaped. The second sliding member 114 is T-shaped. This arrangement can prevent the second sliding member 114 from escaping from the second guide groove.

[0052] Furthermore, at least two second sliding members 114 are provided, and all second sliding members 114 are arranged along the extension direction of the second guide portion 113. In this way, the second rotating shaft 2222 is supported by at least two second sliding members 114, ensuring the stability of the installation of the second rotating shaft 2222.
