This process also includes a bubble removal process to prevent bubbles from being generated inside the module, ensuring the photovoltaic conversion efficiency of the module. Lamination can also enhance the structural strength of the module, reduce the thermal expansion coefficient of the photovoltaic module, and improve the life and performance of the module.

[0004] The above-mentioned laminator also has the following problems when in use: when the above-mentioned laminator is in use, the plate parts placed inside the heating tank need to be manually taken out from the heating tank after the pressing process is completed, which increases the steps of the pressing process, and the heating tank is deep, so it is inconvenient to take out the plate with one hand.

[0005] Therefore, it is necessary to invent a photovoltaic module laminating machine to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a photovoltaic module laminator to solve the problem raised in the above-mentioned background technology that when the above-mentioned laminator is in use, the board parts placed inside the heating groove need to be manually taken out from the heating groove after the pressing process is completed, which increases the pressing process steps, and the depth of the heating groove is relatively deep, making it inconvenient to take out the board with one hand.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a photovoltaic module laminating machine, comprising a processing platform, the top four corners of the processing platform are fixedly connected with support rods, and the top of the support rods is fixedly connected with a top plate, and a cylinder is embedded in the top plate, and a movable plate is fixedly installed on the lower end of the cylinder, and a sealing frame is fixedly installed on the bottom wall of the movable plate, and the sealing frame matches the sealing groove reserved inside the processing platform, a heating groove is also provided inside the processing platform, and a plate body to be processed is placed inside the heating groove, and the processing platform is provided with an ejection assembly to eject the plate body, and a pressing assembly is movably installed inside the movable plate through an installation assembly, and two groups of pressing assemblies are elastically connected by a rebound assembly.

[0008] Preferably, an exhaust pipe is inserted and connected inside the movable plate, and the exhaust pipe is made of a corrugated tube. The ductile exhaust pipe will not affect subsequent operations of the exhaust pipe during the up and down movement of the movable plate.

[0009] Preferably, the ejection assembly includes a cavity opened inside the processing platform, and a bottom plate is slidably installed inside the cavity, and side plates fixedly connected on both sides of the bottom plate are fixedly connected to the two side walls of the movable plate, and a push rod is fixedly connected to the top wall of the bottom plate, and the push rod is movably connected to the conical block. The upward movement of the movable plate drives the push rod fixedly connected to the top wall of the bottom plate to move upward synchronously and then push the conical block to realize the upward movement, and the conical block ejects the processed plate body.

[0010] Preferably, a cylindrical groove is provided inside the conical block, and the cylindrical groove is slidably connected to the push rod, and in the initial state, the upper end of the push rod is located inside the cylindrical groove and does not contact the top wall of the cylindrical groove, so that the push rod needs to move synchronously with the movable plate to rise a certain height before it can support the movement of the conical block, so that the conical block will support the movement of the plate body only after the oblique plate moves completely away from the processed plate body and the sealing frame leaves the sealing groove and there is a distance between it and the top of the sealing groove, so as to facilitate the subsequent removal of the plate body.

[0011] Preferably, the pressing assembly includes a notch opened inside the movable plate, and a long rod is movably installed inside the notch, a snap-in block is movably installed inside the movable square groove reserved inside the long rod through an installation assembly, the snap-in block matches the snap-in square groove reserved inside the movable plate, and an inclined plate is movably sleeved on the outer ring of the long rod, an opening is opened at the lower end of the inclined plate, and a pressing roller is rotatably installed inside the opening.

[0012] Preferably, the outer ring of the long rod is fixedly sleeved with a limiting ring block, and the limiting ring block matches the ring groove reserved in the upper end of the inclined plate and rotatably connected to the limiting ring block, ensuring that the rotational connection between the inclined plate and the long rod will not be displaced.

[0013] Preferably, the installation assembly includes a short rod fixedly connected to the outer wall of the snap-fit ​​block, and the short rod is rotatably connected to the annular groove reserved inside the threaded ring block through the strip groove, the strip groove is connected to the movable square groove, and the threaded ring block is threadedly connected to the thread reserved on the outer ring of the long rod. The threaded ring block is rotated, and the threaded ring block threadedly connected to the thread of the outer ring of the long rod is displaced and drives the snap-fit ​​block to move inside the movable square groove through the short rod. When the snap-fit ​​block moves out of the snap-fit ​​square groove, it is convenient to remove and replace the inclined plate.

[0014] Preferably, the rebound component includes a sliding groove arranged inside the two oblique plates, and the sliding groove is slidably connected to a sliding block inside the sliding groove, and a spring is elastically connected between the two sliding blocks. After the two oblique plates arranged in an inverted "V" shape are separated and moved, the spring is deformed by force. When the movable plate moves upward, the two oblique plates are reset by the spring. At the same time, the two pressing rollers rotatably connected to the lower ends of the two oblique plates slide across the surface of the processed plate body, thereby realizing secondary pressing processing on the plate body. The spring is slidably connected to the oblique plate through the sliding block. This ensures that the spring has an elastic reset effect on the two oblique plates, while also ensuring that the spring will not hinder the pressing processing of the plate body by the pressing roller rotatably connected to the lower end of the oblique plate in the future.

[0015] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0016] 1. The present invention starts the cylinder to mobilize the movable plate to descend, and the pressure rollers connected to the lower ends of the two groups of inclined plates are rotated to descend and contact the surface of the plate body to be processed inside the heating tank. The continuous descent of the movable plate causes the two inclined plates originally set to diverge and move. At this time, the two groups of pressure rollers move across the surface of the plate body to be processed and press the plate body to be processed. The cylinder is subsequently started to drive the movable plate to move upward, and the bottom plate drives the ejector rod to move synchronously to support the conical block to achieve the upward movement. The conical block ejects the processed plate body, which is convenient for the staff to remove the processed plate body so that the laminating device can perform subsequent operations. This makes the placement and removal of the plate body more convenient, saves processing time, and improves processing efficiency.

[0017] 2. Subsequently, the threaded ring block is rotated, and the threaded ring block connected to the outer thread of the long rod is displaced during rotation. At this time, when the threaded ring block is displaced, the short rod drives the clamping block fixedly connected to the short rod to move inside the movable square groove. In this way, when the clamping block moves out of the clamping square groove, it is convenient to remove and replace the inclined plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The present invention provides Figure 1-6A photovoltaic module laminating machine is shown, comprising a processing platform 1, wherein support rods 2 are fixedly connected at the four corners of the top of the processing platform 1, and a top plate 3 is fixedly connected to the top of the support rods 2, and a cylinder 8 is embedded and installed inside the top plate 3, a movable plate 4 is fixedly installed at the lower end of the cylinder 8, and a sealing frame 5 is fixedly installed on the bottom wall of the movable plate 4, and the sealing frame 5 matches the sealing groove 7 reserved inside the processing platform 1, a heating groove 6 is also provided inside the processing platform 1, and a plate body to be processed is placed inside the heating groove 6, and the processing platform 1 is provided with an ejection assembly 9 to eject the plate body, and a pressing assembly 11 is movably installed inside the movable plate 4 through an installation assembly 12, and two groups of pressing assemblies 11 are elastically connected through a rebound assembly 13.

[0029] The interior of the movable plate 4 is connected with an exhaust pipe 10 , and the exhaust pipe 10 is made of a corrugated tube. The exhaust pipe 10 is ductile and will not affect subsequent operations of the exhaust pipe 10 during the upward and downward movement of the movable plate 4 .

[0030] The ejection assembly 9 includes a cavity 901 opened inside the processing platform 1, and a bottom plate 902 is slidably installed inside the cavity 901, and the side plates 903 fixedly connected on both sides of the bottom plate 902 are fixedly connected to the two side walls of the movable plate 4, and the top wall of the bottom plate 902 is fixedly connected to a push rod 904, and the push rod 904 is movably connected to the conical block 905. The upward movement of the movable plate 4 drives the push rod 904 fixedly connected to the top wall of the bottom plate 902 to move upward synchronously and then support the conical block 905 to realize the upward movement, and the conical block 905 ejects the processed plate body.

[0031] A cylindrical groove 906 is provided inside the conical block 905, and the cylindrical groove 906 is slidably connected to the push rod 904, and in the initial state, the upper end of the push rod 904 is located inside the cylindrical groove 906 and does not contact the top wall of the cylindrical groove 906, so that the push rod 904 needs to move synchronously with the movable plate 4 to rise a certain height before it can support the movement of the conical block 905, so that after the inclined plate 113 moves completely away from the processed plate body and the sealing frame 5 leaves the sealing groove 7 and there is a distance between it and the top of the sealing groove 7, the conical block 905 will support the movement of the plate body, so as to facilitate the subsequent removal of the plate body.

[0032] The pressing component 11 includes a notch 111 opened inside the movable plate 4, and a long rod 112 is movably installed inside the notch 111, and a snap-in block 115 is movably installed inside the movable square groove 114 reserved inside the long rod 112 through the mounting component 12, and the snap-in block 115 matches the snap-in square groove 116 reserved inside the movable plate 4, and an outer ring of the long rod 112 is movably sleeved with an inclined plate 113, and an opening 117 is opened at the lower end of the inclined plate 113, and a pressing roller 118 is rotatably installed inside the opening 117.

[0033] The outer ring of the long rod 112 is fixedly sleeved with a limiting ring block 1121, and the limiting ring block 1121 matches the ring groove reserved in the upper end of the inclined plate 113 and rotatably connected to the limiting ring block 1121, ensuring that the rotational connection between the inclined plate 113 and the long rod 112 will not be displaced.

[0034] The mounting assembly 12 includes a short rod 123 fixedly connected to the outer wall of the snap-fit ​​block 115, and the short rod 123 is rotatably connected to the annular groove 125 reserved inside the threaded ring block 122 through the strip groove 124, the strip groove 124 is communicated with the movable square groove 114, and the threaded ring block 122 is threadedly connected to the thread 121 reserved on the outer ring of the long rod 112. The threaded ring block 122 is rotated by turning, and the threaded ring block 122 threadedly connected to the thread 121 on the outer ring of the long rod 112 is displaced and drives the snap-fit ​​block 115 to move inside the movable square groove 114 through the short rod 123. When the snap-fit ​​block 115 moves away from the snap-fit ​​square groove 116, it is convenient to remove and replace the inclined plate 113.

[0035] The rebound component 13 includes a sliding groove 131 arranged inside the two oblique plates 113, and a sliding block 132 is slidably connected inside the sliding groove 131, and a spring 133 is elastically connected between the two sliding blocks 132. After the two oblique plates 113 arranged in an inverted "V" are separated and moved, the spring 133 is deformed by force. When the movable plate 4 moves upward, the two oblique plates 113 are reset by the spring 133. At the same time, the two pressing rollers 118 rotatably connected to the lower ends of the two oblique plates 113 pass over the surface of the processed plate body, so that the plate body is subjected to secondary pressing processing. The spring 133 is slidably connected to the oblique plate 113 through the sliding block 132. In this way, while ensuring that the spring 133 has an elastic reset effect on the two oblique plates 113, it is also ensured that the spring 133 will not hinder the pressing processing of the plate body by the pressing roller 118 rotatably connected to the lower end of the oblique plate 113 in the future.

[0036] Working principle: when using a photovoltaic module laminating machine, first send the board to be processed into the heating tank 6, and then start the cylinder 8 to mobilize the movable plate 4 fixedly connected to the movable end of the cylinder 8 to descend, and the four corners of the movable plate 4 are movably sleeved on the outer rings of the four support rods 2 and are slidably connected to the support rods 2, thereby ensuring the stability of the movable plate 4. During the downward movement of the movable plate 4, the silicone sealing frame 5 fixedly connected to the bottom wall of the movable plate 4 is driven to move downward synchronously and first match the sealing groove 7 reserved inside the processing platform 1. At this time, a closed space is formed between the movable plate 4 and the processing platform 1, and a vacuum is drawn into the closed space through the exhaust pipe 10. At the same time, the continuous descent of the movable plate 4 drives the pressing rollers 118 connected to the rotation of the lower ends of the two groups of oblique plates 113 to descend and contact the surface of the board to be processed pre-placed in the heating tank 6. The continuous descent of the movable plate 4 causes the two oblique plates 113 originally set obliquely to move apart, and the gap angle between the two oblique plates 113 gradually changes. The two pressing rollers 118 connected to the rotation of the lower ends of the two oblique plates 113 move across the surface of the plate to be processed and press the plate to be processed. After the subsequent pressing is completed, the cylinder 8 is started to drive the movable plate 4 to move upward, and then the bottom plate 902 fixedly connected to the side plates 903 on both sides of the movable plate 4 is moved upward in the cavity 901. Similarly, the above operation steps are similar. Since the two oblique plates 113 are elastically connected by the springs 133, when the movable plate 4 moves upward, the two oblique plates 113 are reset at this time. At the same time, the two pressing rollers 118 connected to the rotation of the lower ends of the two oblique plates 113 again pass through the surface of the processed plate. In this way, the plate is subjected to secondary pressing processing to ensure the pressing effect. After the movable plate 4 rises to a certain height, it drives the ejector rod 904 fixedly connected to the top wall of the bottom plate 902 to move synchronously and then push the conical block 905 to achieve the upward movement. The conical block 905 ejects the processed plate, which is convenient for the staff to remove the processed plate so that the laminating device can perform subsequent operations.

[0037] When the inclined plate 113 is subsequently removed and replaced, the threaded ring block 122 is rotated, and the threaded ring block 122 threadedly connected to the outer circle thread 121 of the long rod 112 is displaced during rotation. At this time, when the threaded ring block 122 is displaced, the short rod 123 drives the clamping block 115 fixedly connected to the short rod 123 to move inside the movable square groove 114. In this way, when the clamping block 115 moves out of the clamping square groove 116, it is convenient to remove and replace the inclined plate 113.

[0038] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
