Description

Technical Field

[0001] The present invention relates to the technical field of surface treatment, and in particular to a thin-wall shell surface treatment device used for manufacturing photovoltaic prefabricated cabins. Background Art

[0002] The prefabricated photovoltaic cabin is a modular box structure that integrates the core equipment of a photovoltaic power generation system. It integrates photovoltaic concentrators, inverters, monitoring devices, and other equipment. It is prefabricated in the factory and hoisted on site, significantly shortening the construction period.

[0003] In the process of manufacturing photovoltaic prefabricated cabins, surface grinding equipment is often needed to perform surface treatment on thin-walled shells. At present, common surface grinding equipment generates friction with the surface of thin-walled shells during grinding, which will generate a lot of heat. Generally, cooling water spray is set to be used for cooling treatment, but a pump body is required to drive the treatment, which is costly and wastes water resources. In addition, there is no internal support during the processing of thin-walled shells, which is more prone to deformation and affects the quality of the finished product. Moreover, before grinding, it is generally necessary to operate the fixed structure to fix the thin-walled shell first, and then control the surface grinding equipment to grind. After grinding, the fixation must be released and removed before the next round of operation can be started. The surface of the thin-walled shell that has just been ground is hot, which is not convenient for quick removal, and it is difficult to achieve continuous treatment of the surface of the thin-walled shell. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a thin-wall shell surface treatment device for photovoltaic prefabricated cabin manufacturing, which has the following beneficial effects: 1. The thin-walled shell surface treatment equipment used for the manufacture of photovoltaic prefabricated cabins drives the support assembly to rotate through the feeding assembly, so that the support assembly transfers the position of the thin-walled shell and the thin-walled shell reaches the polishing area, which can smoothly carry out the surface treatment operation, and the uniform speed transfer of the thin-walled shell can realize continuous processing operation, and the alternating conversion of multiple support assemblies can also meet the needs of continuous feeding and achieve the effect of multi-station synchronization. Secondly, through the movement of the feeding assembly, the transverse wheel moves to the arc bar. At this time, the active hydraulic assembly inputs liquid into the liquid storage shell, and the liquid inside the liquid storage shell rises, which can press the upper gas upward. At this time, the double-layer rubber airbag expands and fits into the inner cavity of the thin-walled shell, so that it can play a good internal support role for the thin-walled shell, thereby reducing the problem of thermal deformation that is easy to occur during the surface treatment of the thin-walled shell.

[0016] 2. The thin-walled shell surface treatment equipment used for the manufacture of photovoltaic prefabricated cabins rotates the feeding component, causing the moving wheel to follow and move to the raised part, so that the water delivery component can extract the liquid inside the liquid storage shell and continuously spray it onto the double-layer rubber airbag through the spray component. Then, the double-layer rubber airbag is used to perform heat exchange of the thin-walled shell, and the temperature conducting column can increase the heat exchange effect, which is convenient for cooling the surface treated workpiece. This method can effectively cool the thin-walled shell, reduce the use of equipment, and reduce the overall cost. After cooling, it is convenient for subsequent material removal operations. Secondly, the liquid after spraying can flow back to the liquid storage shell again, thereby ensuring the recycling of the liquid.

[0017] 3. The thin-walled shell surface treatment equipment used for the manufacture of photovoltaic prefabricated cabins drives the support assembly to rotate and feed the material through the feeding assembly. When one end of the active hydraulic assembly moves onto the arc bar, the active hydraulic assembly inputs liquid into the liquid storage shell to increase the liquid, which can lift the gas into the double-layer rubber airbag. The double-layer rubber airbag expands to fit the inner cavity of the thin-walled shell to achieve the positioning of the thin-walled shell. Secondly, the water delivery assembly moves to the raised part and can spray liquid upward through the spray assembly. Since the double-layer rubber airbag fits the inner cavity of the thin-walled shell, it is more conducive to the heat exchange and cooling operation of the thin-walled shell. Since the supporting material is polyvinyl alcohol hydrogel, the material hardens when its temperature is lower than 10°C. Then, during the heat exchange, the supporting material hardens, which can effectively shape multiple pairs of double-layer rubber airbags, while further ensuring the stability of the support for the thin-walled shell, making the thin-walled shell less likely to deform.

The extension rod 2022 passes through the shell 2021 and is fixedly connected to the transverse wheel 2023. The rolling of the transverse wheel 2023 can reduce the movement resistance between the arc bar 105, and the transverse wheel 2023 moves the arc surface position of the arc bar 105. As the curvature of the arc surface increases, the transverse wheel 2023 can move. The transverse wheel 2023 can drive the first piston 2025 to move through the extension rod 2022, so that the liquid enters the liquid storage shell 203, and then the gas above the liquid storage shell 203 can be pressed into the double-layer rubber airbag 2051, so that the double-layer rubber airbag 2051 supports the thin-walled shell; A first spring 2024 is fixedly connected between the first piston 2025 and the shell 2021. The first spring 2024 drives the first piston 2025 to reset, so that the first piston 2025 can introduce the liquid inside the liquid storage shell 203 into the shell 2021. The active hydraulic component 202 is connected to the liquid storage shell 203. A refrigeration component 204 is installed inside the liquid storage shell 203. The refrigeration component 204 is used to cool the reflux liquid, thereby ensuring the continuous use of the subsequent liquid. The liquid storage shell 203 is set on the support component 201. The upper part of the liquid storage shell 203 is connected to the autonomous expansion positioning component 205. The autonomous expansion positioning component 205 includes a double-layer rubber airbag 2051. The double-layer rubber airbag 2051 is expandable. , and then it can be expanded into a double-layer rubber airbag 2051 by gas, so that the thin-walled shell can be smoothly supported. The double-layer rubber airbag 2051 is installed above the liquid storage shell 203. The double-layer rubber airbag 2051 is arranged in the thin-walled shell. The double-layer rubber airbag 2051 is provided with multiple temperature conducting columns 2052. The temperature conducting columns 2052 can increase the temperature conducting points, thereby facilitating heat exchange operations and improving the cooling effect of the thin-walled shell. The double-layer airbag and the temperature conducting columns 2052 are filled with supporting material 2053 in the same space. The horizontal wheel 2023 of the active hydraulic component 202 is moved to the arc bar 105 to input liquid into the liquid storage shell 203. At this time, the autonomous expansion and positioning component 205 automatically expands to position the thin-walled shell; A water supply assembly 206 is provided inside the liquid storage shell 203. The top of the water supply assembly 206 is connected to a spray assembly 207. The spray assembly 207 is located in the autonomous expansion and positioning assembly 205.

[0023] In this embodiment: the motor 1031 drives the feeding disc 1032 to rotate, and the feeding disc 1032 drives the support plate 2011 to rotate, so that the support plate 2011 shifts the position of the thin-walled shell, so that the thin-walled shell reaches the grinding area, and the surface treatment operation can be carried out smoothly. The uniform speed transfer of the thin-walled shell can realize continuous treatment operation, and the multiple support assemblies 201 are alternately converted, which can also meet the needs of continuous feeding and achieve the effect of multi-station synchronization. Secondly, the feeding assembly 103 moves, so that the transverse wheel 2023 moves to the arc bar 105.

The first piston 2025 moves to input liquid into the liquid storage shell 203, and the liquid inside the liquid storage shell 203 rises, and then the upper gas can be pressed upward, causing the double-layer rubber airbag 2051 to expand and fit into the inner cavity of the thin-walled shell, thereby playing a good internal support role for the thin-walled shell, thereby reducing the problem of thermal deformation that is easy to occur during surface treatment of the thin-walled shell.

[0024] Example 2: Reference Figure 7 and Figures 9-11 A thin-wall shell surface treatment device for photovoltaic prefabricated cabin manufacturing includes a spray assembly 207, which includes a joint 2071 and a horizontal plate 2072. The horizontal plate 2072 is rotatably mounted on the joint 2071 through a bearing. The horizontal plate 2072 can maintain stable rotation through the bearing, and the horizontal plate 2072 is connected to the joint 2071. A plurality of spray heads 2073 are arranged on the tangent line of the horizontal plate 2072. The tangent design of the spray head 2073 allows the impact force generated by the spray liquid to smoothly drive the The horizontal plate 2072 rotates to increase the spray area of ​​the double-layer rubber airbag 2051 while maintaining spray uniformity, facilitating heat exchange operations. A nozzle structure 2074 is connected above the horizontal plate 2072. An annular plate 104 is fixedly connected to the bottom wall of the bottom shell 101. The annular plate 104 is provided with two continuous ridges 106.

The autonomous expansion and positioning assembly 205 includes a double-layer rubber airbag 2051, which is installed above the liquid storage shell 203. The double-layer rubber airbag 2051 is set in a thin-walled shell and has multiple temperature conducting columns 2052. The water delivery assembly 206 includes a water delivery cylinder 2061, which is fixedly installed in the liquid storage shell 203. A one-way valve 2062 is installed at the bottom of the water delivery cylinder 2061. The one-way valve 2062 and the one-way drainage pipe 2069 can maintain one-way water inflow to prevent liquid backflow, and the one-way valve 2062 cooperates with the one-way drainage pipe 2069 to switch the drainage operation up and down. The top of the water delivery cylinder 2061 is connected with a second one-way pipe 2068 and a one-way drainage pipe 2069.

The joint 2071 is installed at the top of the water delivery cylinder 2061, and the joint 2071 is connected to the first one-way pipe 2067. The one-way water outflow operation can be maintained through the first one-way pipe 2067 and the second one-way pipe 2068. The first one-way tube 2067 and the second one-way tube 2068 cooperate to switch the water outflow up and down. The first one-way tube 2067 is connected to the bottom of the water cylinder 2061. A second piston 2063 is provided inside the water cylinder 2061. A second spring 2064 is fixedly connected between the second piston 2063 and the bottom wall of the water cylinder 2061. The second spring 2064 can drive the second piston 2063 to reset downward, so that the second piston 2063 can press the liquid in the lower cavity of the water cylinder 2061 out through the first one-way tube 2067. A piston rod 2065 is fixedly connected to the bottom of the second piston 2063. The piston rod 2065 passes through the water cylinder 2061 and is fixedly connected to the moving wheel 2066. The rolling property of the moving wheel 2066 can reduce the movement resistance with the raised portion 106, thereby maintaining the smooth movement of the moving wheel 2066.

[0025] In this embodiment, the feeding assembly 103 rotates to move the moving wheel 2066 to the raised portion 106, so that the moving wheel 2066 drives the piston rod 2065 and the second piston 2063 to move. The second piston 2063 extracts liquid through the one-way valve 2062, and the second piston 2063 presses the liquid into the joint 2071 through the second one-way tube 2068. When the moving wheel 2066 moves to the notch of the raised portion 106, the second spring 2064 drives the second piston 2063 to reset, so that the liquid is output through the first one-way tube 2067, and the second piston 2063 also introduces liquid into the water delivery cylinder 206 through the one-way drainage tube 2069. 1, the output liquid enters the horizontal plate 2072. Due to the tangential design of the spray head 2073, the spray head 2073 rotates to spray. Secondly, the liquid is also sprayed onto the double-layer rubber airbag 2051 through the spray head structure 2074, and then the heat exchange of the thin-walled shell is carried out through the double-layer rubber airbag 2051. The heat conducting column 2052 can increase the heat exchange effect, which is convenient for cooling the surface-treated workpiece. This method can effectively cool the thin-walled shell, reduce the use of equipment, and reduce the overall cost. After cooling, it is convenient for subsequent material removal operations. Secondly, the liquid after spraying can flow back to the liquid storage shell 203 again, thereby ensuring the recycling of the liquid.

[0026] Example 3: Reference Figure 2-Figure 7 A thin-walled shell surface treatment device for manufacturing photovoltaic prefabricated cabins includes a thin-walled shell surface treatment mechanism 100, which includes a bottom shell 101 and a polishing assembly 102. A feeding assembly 103 is provided in the bottom shell 101, and an arc-shaped strip 105 is fixedly connected to the side wall of the bottom shell 101. An annular plate 104 is fixedly connected to the bottom wall of the bottom shell 101, and the annular plate 104 is provided with two continuous protrusions 106. The polishing auxiliary mechanism 200 includes a support assembly 201, which is used to place the thin-walled shell. The support assembly 201 is provided with an active hydraulic assembly 202, which is connected to a liquid storage shell 203. The liquid storage shell 203 is provided on the support assembly 201. The upper part of the liquid storage shell 203 is connected to an autonomous expansion and positioning assembly 205. When the transverse wheel 2023 of the active hydraulic assembly 202 moves onto the arc-shaped bar 105, liquid is input into the liquid storage shell 203. At this time, the autonomous expansion and positioning assembly 205 automatically expands to position the thin-walled shell. A water supply assembly 206 is provided inside the liquid storage shell 203. The top of the water supply assembly 206 is connected to a spray assembly 207. The spray assembly 207 is located in the autonomous expansion and positioning assembly 205. The moving wheel 2066 of the water supply assembly 206 moves to the raised portion 106 of the annular plate 104, so that the water supply assembly 206 sprays upward through the spray assembly 207, and the thin-walled shell is cooled by heat exchange through the autonomous expansion and positioning assembly 205.

[0027] In this embodiment, the feeding component 103 drives the support component 201 to rotate and feed. When one end of the active hydraulic component 202 moves onto the arc-shaped bar 105, the active hydraulic component 202 inputs liquid into the liquid storage shell 203, increasing the liquid, which can lift the gas into the double-layer rubber airbag 2051. The double-layer rubber airbag 2051 expands to fit the inner cavity of the thin-walled shell, thereby achieving the positioning of the thin-walled shell. Secondly, the water delivery component 206 moves to the raised portion 106 and can spray liquid upward through the spray component 207. Since the double-layer rubber airbag 2051 fits the inner cavity of the thin-walled shell, it is more conducive to the heat exchange and cooling operation of the thin-walled shell. Moreover, since the supporting material 2053 is polyvinyl alcohol hydrogel, the material hardens when its temperature is lower than 10°C. Then, during the heat exchange, the supporting material 2053 hardens, which can effectively shape the double-layer rubber airbag 2051 and further ensure the stability of the support for the thin-walled shell, making the thin-walled shell less likely to deform.

[0028] Working principle: When the surface of the thin-walled shell of the photovoltaic prefabricated cabin is processed, the thin-walled shell is placed on the support plate 2011, so that the limit block 2013 positions the thin-walled shell, and then the motor 1031 drives the feeding disk 1032 to rotate, so that the grinding auxiliary mechanism 200 rotates with the feeding disk 1032, and when the transverse wheel 2023 moves onto the arc strip 105, the arc surface of the arc strip 105 squeezes the transverse wheel 2023 to move, and the transverse wheel 2023 drives the extension rod 2022 to move, and the extension rod 2022 drives the first piston 2025 to move, and the first piston 2025 drives the first spring 2024 to deform, and the first piston 2025 inputs the liquid in the outer shell 2021 into the liquid storage shell 203. As the liquid increases, the gas above the liquid storage shell 203 continues to enter the double-layer rubber airbag 2051, and the double-layer rubber airbag 2051 expands and expands, so that the double-layer rubber airbag 2051 fits the inner cavity of the thin-walled shell for maintenance; Subsequently, the moving wheel 2066 moves to the raised portion 106, causing the moving wheel 2066 to drive the piston rod 2065 to rise, and the piston rod 2065 drives the second piston 2063 to rise, and the second piston 2063 drives the second spring 2064 to deform, and the second piston 2063 extracts the liquid inside the liquid storage shell 203 through the one-way valve 2062, and pushes the liquid above the second piston 2063 into the joint 2071 through the second one-way tube 2068. When the moving wheel 2066 moves to the recess between the two raised portions 106, the second spring 2064 drives the piston to reset downward. At this time, liquid is introduced into the upper chamber of the water delivery cylinder 2061 through the one-way drainage tube 2069, and the second piston 2063 can also input the liquid into the connector 2071 again through the first one-way tube 2067, thereby allowing the water delivery component 206 to continuously deliver water upward through the raised portion 106, and then enter the horizontal plate 2072 for spraying. The tangential design of the spray head 2073 allows it to rotate to spray. At the same time, the spray head structure 2074 sprays liquid synchronously, so that the liquid is sprayed into the inner cavity of the double-layer rubber airbag 2051, and the support material 2053 hardens, thereby shaping the double-layer rubber airbag 2051. Secondly, since the electric push rod 1022 pre-adjusts the grinder 1023 to the appropriate position, the thin-walled shell can be surface-treated after passing through the grinder 1023. Since the grinding and spraying operations are carried out simultaneously, the heat generated during the grinding process can be exchanged and cooled by the double-layer rubber airbag 2051. After cooling, the liquid returns to the liquid storage shell 203 and is further cooled by the refrigeration component 204, and the thin-walled shell continues to be transported. When the moving wheel 2066 disengages from the arc strip 105, the first spring 2024 drives the first piston 2025 to reset, causing the liquid to flow back into the outer shell 2021. When the thin-walled shell is transported to the initial position, the thin-walled shell is then taken out, and the feeding component 103 drives the supporting component 201 to perform switching movement, thereby continuously processing the thin-walled shell.
