Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, and in particular to a pressing device for processing photovoltaic panels. Background Technology

[0002] Photovoltaic panels are core components that convert solar energy into electrical energy through the photovoltaic effect. Their development is undergoing a dual upgrade of technological breakthroughs and cost optimization. In the photovoltaic panel processing stage, the use of butyl hot melt adhesive is crucial. However, butyl hot melt adhesive is solid under normal conditions. In the production and processing of photovoltaic panels, solid butyl adhesive needs to be melted into a fluid to meet the process requirements.

[0003] Traditional adhesive melting and conveying devices in the prior art either melt unevenly, resulting in poor adhesive flow and affecting the continuity and uniformity of coating, or have insufficient pressure to convey the adhesive, causing the adhesive to be unable to be smoothly delivered to the designated position, which has an adverse effect on the processing efficiency and quality of photovoltaic panels. Summary of the Invention

[0004] This application provides a pressure bonding device for photovoltaic panel processing, which can efficiently melt solid butyl hot melt adhesive into a fluid and stably and smoothly deliver the adhesive to the required position for photovoltaic panel processing, while ensuring uniform melting of the adhesive and improving the reliability and efficiency of pressure delivery.

[0005] The adhesive pressing device for processing photovoltaic panels provided in this application adopts the following technical solution: A pressure bonding device for processing photovoltaic panels includes a base plate, a top plate, and a material conveying pipe. The top plate is mounted on top of the base plate via a pair of lifting components, and a support plate is mounted on the bottom of the top plate via a pair of first connecting rods. A heating pressure plate is mounted on the bottom of the support plate via a pair of second connecting rods. The material conveying pipe is mounted on the top surface of the heating pressure plate and communicates with the bottom surface of the heating pressure plate. A glue outlet is installed on the outer wall of the material conveying pipe near the top. The material conveying pipe is equipped with a material conveying mechanism that can transport the glue from the bottom of the heating pressure plate to the glue outlet.

[0006] By adopting the above technical solution, a barrel containing solid butyl rubber is placed on the base at the position corresponding to the bottom of the heating pressure plate. The lifting component drives the top plate to gradually move down, causing the heating pressure plate at the bottom of the conveying pipe to move down into the barrel to squeeze the solid butyl rubber. During the squeezing process, the heating pressure plate melts the solid butyl rubber in the barrel, turning it into a fluid that flows to the center of the bottom of the heating pressure plate. Then, the conveying mechanism gradually pushes the butyl rubber at the center of the bottom of the heating pressure plate upward, allowing it to flow out from the outlet. This ensures that the butyl rubber can be continuously and evenly output from the outlet to the photovoltaic panel processing area, effectively solving the problems of uneven rubber melting and insufficient pressure in traditional devices. This improves the efficiency and reliability of butyl rubber use during photovoltaic panel processing and ensures the processing quality of photovoltaic panels.

[0007] Preferably, the lifting assembly includes a first cylinder; the first cylinder is vertically mounted on the top surface of the base plate; the top plate is located on top of the first cylinder, and the bottom surface of the top plate is fixedly connected to the output end of the first cylinder.

[0008] By adopting the above technical solution, the first cylinder is used to provide driving force to drive the top plate to rise and fall, control the downward pressing action of the heating pressure plate in the rubber barrel, realize the extrusion of solid butyl rubber in the rubber barrel, and promote the flow of the melted rubber material into the conveying channel in the heating pressure plate.

[0009] Preferably, the glue delivery mechanism includes a second cylinder and a liquid-priming spoon; the second cylinder is mounted on the top surface of the support plate, and the output end of the second cylinder is coaxially fixed to a plunger rod extending into the delivery pipe; the liquid-priming spoon is mounted on the bottom end of the plunger rod; a first switching valve and a second switching valve are provided in the delivery pipe; the first switching valve is positioned higher than the second switching valve but lower than the glue outlet; the second switching valve is positioned higher than the liquid-priming spoon; a stop block located between the first and second switching valves is fixed to the outer wall of the plunger rod.

[0010] By adopting the above technical solution, when conveying fluid butyl rubber, the second cylinder drives the plunger rod to move up and down reciprocally. During the downward movement of the plunger rod, the first switch valve opens and the second switch valve closes. At this time, the liquid scoop moves down to scoop up the butyl rubber. During the upward movement of the plunger rod, the first switch valve closes and the second switch valve opens, causing the fluid butyl rubber to be gradually conveyed to the cavity between the first and second switch valves. When the fluid butyl rubber fills this cavity, during the downward movement of the plunger rod again, the baffle on the plunger rod will squeeze the butyl rubber in this cavity, causing the rubber to pass through the second switch valve and be discharged from the outlet. During the continuous up and down movement of the plunger rod, the rubber is stably conveyed.

[0011] Preferably, the first cylinder is equipped with a pressure boosting valve.

[0012] By adopting the above technical solution, the pressure booster valve can increase the downward pressure of the heating platen, ensuring sufficient pressure is provided when extruding the rubber material, allowing the rubber material to flow more smoothly into the heating platen, thereby improving the extrusion effect and reliability.

[0013] Preferably, the heating platen includes a connecting plate, a heating plate, and an extrusion plate; the connecting plate is disposed at the bottom end of the feed pipe via a pair of second connecting rods, and a first through hole communicating with the feed pipe is formed on the connecting plate; the heating plate is fixedly connected to the bottom surface of the connecting plate, and a second through hole coaxially communicating with the first through hole is formed on the heating plate; the extrusion plate is fixedly connected to the bottom surface of the heating plate, and a third through hole coaxially communicating with the second through hole is formed on the extrusion plate; an exhaust channel communicating with the first through hole and the top surface of the connecting plate is provided inside the connecting plate; an exhaust valve is installed on the top surface of the connecting plate corresponding to the top position of the exhaust channel.

[0014] By adopting the above technical solution, the first through hole, the second through hole and the third through hole cooperate to form a channel for conveying fluid butyl rubber. During the conveying process of fluid butyl rubber, the exhaust valve is in the closed state. After the conveying of the rubber material in the rubber barrel is completed, the extrusion plate will stick tightly to the bottom wall of the rubber barrel. At this time, the exhaust valve can be opened to connect the external environment with the conveying channel of the heating pressure plate, so as to avoid the conveying channel of the heating pressure plate being in a negative pressure state, so that the staff can replace the rubber barrel.

[0015] Preferably, the bottom surface of the extrusion disc has a groove that communicates with the third through hole.

[0016] By adopting the above technical solution, the groove opened at the bottom of the extrusion plate can be used to guide the flow of the hot-melted molten rubber, so as to facilitate the flow of the fluid butyl rubber to the third through hole in the center of the extrusion plate, in order to prepare for the subsequent delivery of the fluid rubber.

[0017] Preferably, the top surface of the connecting disc is fixedly connected to a cover surrounding the outside of the conveying pipe.

[0018] By adopting the above technical solution, the outer casing of the conveying pipe is used to support and protect the conveying pipe, improve the stability of the conveying pipe, reduce the possibility of damage to the conveying pipe, and increase its service life.

[0019] Preferably, the bottom surface of the base plate is provided with a set of casters, and the top surface of the base plate is equipped with a handle.

[0020] By adopting the above technical solution, the omnidirectional wheels facilitate the movement of the device and improve its flexibility during use.

[0021] Preferably, a set of third cylinders is installed on the top surface of the base plate; the output ends of each set of third cylinders are coaxially fixed with piston rods that penetrate the base plate; and a pressure plate is fixed to the bottom end of the piston rods.

[0022] By adopting the above technical solution, when the rubber material is pressed, the third cylinder is activated to drive the piston rod to move downward, causing the pressure plate to press onto the ground, increasing the contact area between the bottom plate and the ground, and improving the overall stability of the device during operation.

[0023] Preferably, a rubber pad is installed on the bottom surface of the pressure plate.

[0024] By adopting the above technical solution, the rubber pad increases the friction between the pressure plate and the ground, further improving the overall stability of the device during operation.

[0025] In summary, this application has the following beneficial effects: 1. During the melt conveying process, the lifting component drives the heating plate at the bottom of the conveying pipe to gradually move down and extrude and melt the fixed butyl rubber, turning it into a fluid that flows to the center of the bottom of the heating plate. Then, the conveying mechanism gradually pushes the butyl rubber at the center of the bottom of the heating plate upward, so that the butyl rubber flows out from the outlet. This ensures that the butyl rubber can be continuously and evenly output from the outlet to the photovoltaic panel processing area, thus guaranteeing the processing quality of the photovoltaic panels. 2. Through the coordinated operation of the first cylinder and the booster valve, sufficient and adjustable downward extrusion force is provided to the heated pressure plate, ensuring that the adhesive flows smoothly to the center of the heated pressure plate, improving the extrusion effect and reliability, and preparing for the subsequent conveying of adhesive. 3. During the pressing and conveying process, the third cylinder is activated to drive the piston rod to move downward, causing the pressure plate to press onto the ground, increasing the contact area between the bottom plate and the ground. By adding a rubber pad to the bottom of the pressure plate, the friction between it and the ground is increased, thereby improving the stability of the device during operation.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] This invention discloses a pressure bonding device for processing photovoltaic panels, such as... Figure 1 and Figure 2 As shown, it includes a base plate 1, a top plate 2, a conveying pipe 3, and a heating plate 5. The top plate 2 is horizontally installed on the top of the base plate 1 via a pair of lifting components 4. A horizontal support plate 22 located at the bottom of the top plate 2 is connected to the top plate 2 via a pair of first connecting rods 21. The heating plate 5 is horizontally installed at the bottom of the support plate 22 via a pair of second connecting rods 23. A conveying channel is vertically installed inside the heating plate 5, and the heating plate 5 can melt solid butyl rubber into a fluid. The conveying pipe 3 is vertically installed on the top of the heating plate 5 and is connected to the conveying channel.

[0030] The rubber barrel containing solid butyl rubber is placed on the base at the position corresponding to the bottom of the heating platen 5. The lifting component 4 moves the top plate 2 down, causing the heating platen 5 at the bottom of the conveying pipe 3 to move down into the rubber barrel to squeeze the solid butyl rubber. During the squeezing process, the heating platen 5 will heat melt the solid butyl rubber in the rubber barrel, turning it into a fluid that flows into the conveying channel of the heating platen 5, preparing it for subsequent conveying.

[0031] like Figure 1 and Figure 2 As shown, the lifting assembly 4 includes a first cylinder 41, which is vertically mounted on the top surface of the base plate 1. The first cylinder 41 is located at the bottom of the top plate 2, and the output end of the first cylinder 41 is fixedly connected to the bottom surface of the top plate 2. A pressure boosting valve 42 is provided on the first cylinder 41.

[0032] The first cylinder 41 can drive the top plate 2 to rise and fall, control the downward pressing action of the heating pressure plate 5 in the rubber barrel, and realize the extrusion of solid butyl rubber in the rubber barrel. The pressure boosting valve 42 can increase the downward pressure of the heating pressure plate 5 so as to promote the smooth flow of the rubber material into the conveying channel of the heating pressure plate 5.

[0033] like Figure 2 and Figure 3 As shown, the heating plate 5 includes a connecting plate 51, a heating plate 52, and an extrusion plate 53. The top surface of the connecting plate 51 is horizontally mounted on the bottom of the support plate 22 via a pair of second connecting rods 23. A first through hole 511 is vertically opened at the center of the connecting plate 51. The heating plate 52 is fixedly connected to the bottom surface of the connecting plate 51. A second through hole 521, coaxial with and communicating with the first through hole 511, is vertically opened at the center of the heating plate 52. The heating plate 52 adopts an existing electric heating method, which is existing technology and will not be described in detail here. The extrusion plate 53 is fixedly mounted on the bottom surface of the connecting plate 51. A third through hole 531, coaxial with and connected to the second through hole 521, is vertically opened at the center of the extrusion plate 53, which is attached to the bottom surface of the heating plate 52. The material conveying pipe 3 is vertically fixed to the top surface of the connecting plate 51 and communicates with the first through hole 511. The first through hole 511, the second through hole 521 and the third through hole 531 cooperate to form a material conveying channel. An exhaust channel 512, which communicates with the top surface of the connecting plate 51, is inclined upward on the inner wall of the first channel. An exhaust valve 513 is installed on the top surface of the connecting plate 51 at the top position of the exhaust channel 512.

[0034] The first through hole 511, the second through hole 521, and the third through hole 531 can cooperate to form a channel for conveying fluid butyl rubber. During the conveying of fluid butyl rubber, the exhaust valve 513 is in the closed state. After the conveying of the rubber material in the rubber barrel is completed, the extrusion plate 53 will be pressed tightly against the bottom wall of the rubber barrel. The exhaust valve 513 is opened to connect the external environment with the conveying channel of the heating pressure plate 5, so as to avoid the conveying channel of the heating pressure plate 5 being in a negative pressure state, so as to replace the rubber barrel.

[0035] like Figure 3 and Figure 4 As shown, the bottom surface of the extrusion plate 53 has multiple grooves 532 that communicate with the third through hole 531, and the multiple grooves 532 are evenly distributed along the outer periphery of the third through hole 531.

[0036] The groove 532 at the bottom of the extrusion disc 53 can be used to guide the hot melted rubber compound, so as to facilitate the flow of the fluid butyl rubber to the third through hole 531 in the center of the extrusion disc 53.

[0037] like Figure 2 and Figure 5As shown, a glue outlet 31 is provided on the outer wall near the top of the conveying pipe 3. A glue conveying mechanism 6 is provided inside the conveying pipe 3. The glue conveying mechanism 6 can transport the fluid glue from the conveying channel to the glue outlet 31. The glue conveying mechanism 6 includes a second cylinder 61, a liquid scoop 62, and a stop block 64. The second cylinder 61 is installed on the top surface of the support plate 22. The output end of the second cylinder 61 is coaxially fixed to a plunger rod 63 that passes through the support plate 22 and extends into the conveying pipe 3. The liquid scoop 62 is installed on the outer wall of the bottom end of the plunger rod 63. A first switching valve 32 and a second switching valve 33 are provided inside the conveying pipe 3. The first switching valve 32 is positioned higher than the second switching valve 33 and lower than the glue outlet 31. The second switching valve 33 is positioned higher than the liquid scoop 62. The stop block 64 is coaxially fixed to the outer wall of the plunger rod 63. The stop block 64 is positioned lower than the first switching valve 32 and higher than the second switching valve 33.

[0038] When conveying fluid butyl rubber, the second cylinder 61 drives the plunger rod 63 to move up and down reciprocally. When the plunger rod 63 moves down, the first switch valve 32 opens and the second switch valve 33 closes, and the liquid scoop 62 moves down to scoop up the fluid butyl rubber. When the plunger rod 63 moves up, the first switch valve 32 closes and the second switch valve 33 opens, causing the fluid butyl rubber to be gradually conveyed to the cavity between the first switch valve 32 and the second switch valve 33. When the fluid butyl rubber fills this cavity, during the process of the plunger rod 63 moving down again, the baffle 64 on the plunger rod 63 will squeeze the butyl rubber in this cavity, causing the rubber to pass through the second switch valve 33 and be discharged from the outlet 31, so that the butyl rubber can be continuously and evenly output from the outlet 31 to the photovoltaic panel processing area.

[0039] like Figure 1 and Figure 2 As shown, a cover 34 surrounding the outside of the conveying pipe 3 is vertically fixed to the top surface of the connecting plate 51.

[0040] The cover 34 is provided to support and protect the conveying pipe 3, improve the stability of the conveying pipe 3, reduce the possibility of damage to the conveying pipe 3, and extend the service life of the conveying pipe 3.

[0041] like Figure 1 As shown, a set of casters 11 is provided on the bottom surface of the base plate 1, and the casters 11 are distributed at the four corners of the bottom surface of the base plate 1. A handle 12 is provided on the top surface of the base plate 1.

[0042] By installing casters 11 at the bottom of the base plate 1, the device can be moved easily, thereby improving the flexibility of the device during use.

[0043] like Figure 1 and Figure 6As shown, a set of third cylinders 13 are installed on the top surface of the base plate 1. The set of third cylinders 13 are located near the four corners of the top surface of the base plate. The output end of each third cylinder 13 is coaxially fixed with a piston rod 131 that penetrates the base plate 1. The bottom end of the piston rod 131 is fixed with a pressure plate 14, and the bottom surface of the pressure plate 14 is fixed with a rubber pad 141.

[0044] During the pressing and conveying process, the third cylinder 13 is activated to drive the piston rod 131 to move downward, causing the pressure plate 14 to press onto the ground, increasing the contact area between the base plate 1 and the ground. By adding a rubber pad 141 to the bottom surface of the pressure plate 14, the friction between the pressure plate 14 and the ground is increased, thereby improving the stability of the device during operation.

[0045] Working principle: When hot-melting and conveying the rubber compound, the rubber compound barrel containing solid butyl rubber is placed on the top of the base at the position corresponding to the bottom of the heating pressure plate 5. The first cylinder 41 provides driving force to drive the top plate 2 to gradually move down, causing the heating pressure plate 5 at the bottom of the conveying pipe 3 to move down into the rubber compound barrel to squeeze the fixed butyl rubber. During the extrusion process, the heating plate 52 will hot-melt the solid butyl rubber in the rubber compound barrel, turning it into a fluid and flowing to the third through hole 531 at the bottom center of the extrusion plate 53, in order to prepare for the subsequent conveying of fluid rubber compound. When hot-melting and extruding the rubber compound, the downward pressure of the heating pressure plate 5 can be increased by the pressure boosting valve 42, so as to make the rubber compound flow more smoothly to the bottom center of the extrusion plate 14. When conveying fluid butyl rubber, the second cylinder 61 drives the plunger rod 63 to move up and down reciprocally. When the plunger rod 63 moves down, the first switch valve 32 opens and the second switch valve 33 closes, and the liquid scoop 62 moves down to scoop up the fluid butyl rubber. When the plunger rod 63 moves up, the first switch valve 32 closes and the second switch valve 33 opens, causing the fluid butyl rubber to be gradually conveyed to the cavity between the first switch valve 32 and the second switch valve 33. When the fluid butyl rubber fills this cavity, when the plunger rod 63 moves down again, the baffle 64 on the plunger rod 63 will squeeze the butyl rubber in this cavity, causing the rubber to pass through the second switch valve 33 and be discharged from the outlet 31. This achieves stable conveying of the rubber during the continuous up and down movement of the plunger rod 63, and ensures that the butyl rubber can be continuously and evenly output from the outlet 31 to the photovoltaic panel processing area. During the pressing and conveying process, the third cylinder 13 can be activated to drive the piston rod 131 to move downward, causing the pressure plate 14 to press onto the ground, increasing the contact area between the base plate 1 and the ground, and improving the stability of the device during the pressing process.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
