The second hot press assembly 16 is located in the working chamber 18, and the second hot press curved surface 22 is opposite to the first hot press curved surface 20. The hot press machine 100 is configured to utilize the first hot press curved surface 20 and the second hot press curved surface 22 to apply hot pressure to a workpiece 200 located between the first hot press curved surface 20 and the second hot press curved surface 22 to perform hot press molding on the workpiece 200.

[0041] In the above-mentioned hot press machine 100, through the relative movement of the first hot press curved surface 20 and the second hot press curved surface 22, thermal pressure is provided to the workpiece 200 located between the first hot press curved surface 20 and the second hot press curved surface 22, and then the workpiece 200 is hot pressed and molded. The above-mentioned hot press machine 100 can laminate the battery cell and the flat glass together to avoid the battery cell from breaking.

[0042] Specifically, in one embodiment, the hot press machine 100 may be a pre-fixed curved surface hot press machine 100. After the workpiece 200 is hot-pressed and molded by the hot press machine 100, the components of each layer of the workpiece 200 are pre-fixed and then sent to another device for further processing.

[0043] Optionally, in one embodiment, the workpiece 200 may be a photovoltaic laminate. Before the hot pressing molding, the photovoltaic laminate may be a planar stacked structure including but not limited to a back sheet, a glue layer, a battery sheet, and a front sheet, such as Figure 8 After hot pressing and molding, the photovoltaic laminate is pressed into a curved surface structure by the first hot pressing curved surface 20 and the second hot pressing curved surface 22, as shown in FIG. Fig. 9 As shown. Both the back plate and the front plate can be glass plates, and the heat press 100 can laminate the battery cell and the flat glass together to prevent the battery cell from breaking. The battery cell can convert light energy into electrical energy.

[0044] The present invention does not specifically limit the shape and material of the housing 12. Figure 1 In the embodiment, the shell 12 is in an elongated shape, and the workpiece 200 cavity is in a rectangular shape. The shell 12 can be made of metal (such as stainless steel, iron) or high temperature resistant plastic, which can ensure the normal operation of the hot press 100.

[0045] The first hot pressing assembly 14 and the second hot pressing assembly 16 are both located in the working chamber 18. Figure 2 In the embodiment, the first hot pressing assembly 14 is an upper hot pressing assembly, and the second hot pressing assembly 16 is a lower hot pressing assembly. It can be understood that the present invention does not specifically limit the positions of the first hot pressing assembly 14 and the second hot pressing assembly 16.

[0046] Optionally, the first hot pressing curved surface 20 and the second hot pressing curved surface 22 may move toward each other by fixing the first hot pressing curved surface 20 and moving the second hot pressing curved surface 22 toward the first hot pressing curved surface 20 , thereby applying thermal pressure to the workpiece 200 between the first hot pressing curved surface 20 and the second hot pressing curved surface 22 .

[0047] Optionally, the first hot pressing surface 20 and the second hot pressing surface 22 may move toward each other while the second hot pressing surface 22 is fixed and the first hot pressing surface 20 moves toward the second hot pressing surface 22 , thereby applying thermal pressure to the workpiece 200 between the first hot pressing surface 20 and the second hot pressing surface 22 .

[0048] Optionally, the first hot pressing curved surface 20 and the second hot pressing curved surface 22 move toward each other, and the second hot pressing curved surface 22 moves toward the first hot pressing curved surface 20, and the first hot pressing curved surface 20 moves toward the second hot pressing curved surface 22, so as to apply thermal pressure to the workpiece 200 between the first hot pressing curved surface 20 and the second hot pressing curved surface 22. The two hot pressing curved surfaces simultaneously apply thermal pressure to the workpiece 200, which can further prevent the workpiece 200 from being broken due to excessive local stress.

[0049] The application of thermal pressure to the workpiece 200 may be understood as that when the thermal pressing curved surface contacts the workpiece 200 , the thermal pressing curved surface may apply pressure to the workpiece 200 and heat the workpiece 200 at the same time.

[0050] In some embodiments, the first hot pressing assembly 14 includes a first elastic hot pressing platen 24 having a first hot pressing curved surface 20 . The second hot pressing assembly 16 includes a second elastic hot pressing platen 26 having a second hot pressing curved surface 22 .

[0051] Therefore, the elastic first hot pressing plate 24 and the second hot pressing plate 26 can provide a buffer force to prevent the workpiece 200 from breaking due to excessive pressure.

[0052] Specifically, in one embodiment, the workpiece 200 may include a battery cell, glass, etc. The elastic first hot pressing plate 24 and the second hot pressing plate 26 may provide a certain buffer force during the hot pressing process to prevent the battery cell and glass from breaking during the hot pressing process.

[0053] The size of the hot pressing platen can be as long as it meets the hot pressing requirements of the workpiece 200 , and the utility model does not make any specific limitation. Optionally, the size of the first hot pressing platen 24 is the same as the size of the second hot pressing platen 26 .

[0054] Please combine Figure 2 , Figure 3 and Figure 7 , the first hot pressing plate 24 is an upper hot pressing plate, the first hot pressing curved surface 20 is the lower surface of the upper hot pressing plate, the second hot pressing plate 26 is a lower hot pressing plate, and the second hot pressing curved surface 22 is the upper surface of the lower hot pressing plate. It can be understood that the utility model does not specifically limit the shape of the hot pressing curved surface. The first hot pressing plate 24 and the second hot pressing plate 26 can be curved plates.

[0055] In some embodiments, the first hot pressing plate 24 includes an elastic rubber member or an elastic plastic member, and the second hot pressing plate 26 includes an elastic rubber member or an elastic plastic member.

[0056] Therefore, the material of the hot press plate is easy to obtain and the cost is low.

[0057] Specifically, the material of the first hot pressing plate 24 and the material of the second hot pressing plate 26 may be the same or different.

[0058] The present invention is not specifically limited.

[0059] Optionally, the first hot pressing plate 24 can be manufactured in an integral manner, and the second hot pressing plate 26 can be manufactured in an integral manner, which can improve manufacturing efficiency.

[0060] In some embodiments, the first hot pressing assembly 14 includes a first driving member 28 and a first connecting rod 30, the first connecting rod 30 connects the first driving member 28 and the first hot pressing plate 24, the first driving member 28 is configured to drive the first connecting rod 30 to drive the first hot pressing plate 24 to move closer to the second hot pressing plate 26 and move away from the second hot pressing plate 26, and / or;

[0061] The second hot pressing assembly 16 includes a second driving member 32 and a second connecting rod 34 , the second connecting rod 34 connects the second driving member 32 and the second hot pressing plate 26 , and the second driving member 32 is configured to drive the second connecting rod 34 to drive the second hot pressing plate 26 to move closer to the first hot pressing plate 24 and away from the first hot pressing plate 24 .

[0062] Thus, the two hot press plates can be moved closer to or farther from each other using the first drive member 28 and / or the second drive member 32 .

[0063] Specifically, initially, if the distance between the two hot press plates does not meet the requirement for placing the workpiece 200, the first driving member 28 can drive the first connecting rod 30 to drive the first hot press plate 24 to move away from the second hot press plate 26, and / or the second driving member 32 can drive the second connecting rod 34 to drive the second hot press plate 26 to move away from the first hot press plate 24, so as to increase the distance between the two hot press plates, so that the workpiece 200 can be easily placed between the two hot press plates.

[0064] When the distance between the two hot pressing plates is appropriate, the workpiece 200 can be placed on the upper surface of the lower hot pressing plate. In one embodiment, during the hot pressing process, the first driving member 28 drives the first connecting rod 30 to drive the first hot pressing plate 24 to move close to the second hot pressing plate 26, and at the same time, the second driving member 32 drives the second connecting rod 34 to drive the second hot pressing plate 26 to move close to the first hot pressing plate 24, so that the two hot pressing plates simultaneously apply thermal pressure to the workpiece 200 to perform hot pressing and molding on the workpiece 200.

[0065] After the hot pressing is completed, the first driving member 28 can drive the first connecting rod 30 to drive the first hot pressing plate 24 to move away from the second hot pressing plate 26, and / or the second driving member 32 can drive the second connecting rod 34 to drive the second hot pressing plate 26 to move away from the first hot pressing plate 24, so as to increase the distance between the two hot pressing plates, so that the workpiece 200 can be easily taken out and placed in the next workstation.

[0066] In certain embodiments, the first drive member 28 comprises a pneumatic cylinder and the second drive member 32 comprises a pneumatic cylinder.

[0067] Therefore, the driving method of the first driving member 28 and the second driving member 32 is simple and efficient.

[0068] Specifically, the first connecting rod 30 and the second connecting rod 34 can be piston rods. The piston rod and the cylinder can be nested with each other, and the piston rod can be moved up and down along the cylinder, thereby driving the entire hot press plate to move up and down. Figure 3In the embodiment, when the cylinder of the first hot pressing assembly 14 drives the first connecting rod 30 to move upward, the first hot pressing plate 24 moves away from the second hot pressing plate 26. When the cylinder of the first hot pressing assembly 14 drives the first connecting rod 30 to move downward, the first hot pressing plate 24 moves close to the second hot pressing plate 26, that is, a downward pressure can be applied to the workpiece 200 (such as a photovoltaic laminate) to perform hot pressing molding.

[0069] When the cylinder of the second hot pressing assembly 16 drives the second connecting rod 34 to move upward, the second hot pressing plate 26 moves close to the first hot pressing plate 24, that is, an upper pressure can be applied to the workpiece 200 (such as a photovoltaic laminate) to perform hot pressing molding. When the cylinder of the second hot pressing assembly 16 drives the second connecting rod 34 to move downward, the second hot pressing plate 26 moves away from the first hot pressing plate 24.

[0070] exist Figure 3 and Figure 4 In the embodiment, the first hot pressing assembly 14 includes two first connecting rods 30, which are respectively connected to the positions near the left and right sides of the upper surface of the first hot pressing plate 24. The second hot pressing assembly 16 includes two second connecting rods 34, which are respectively connected to the positions near the left and right sides of the lower surface of the second hot pressing plate 26. Each connecting rod is connected to a driving member, thereby providing a more uniform pressure on the workpiece 200.

[0071] In some embodiments, a first electric heating plate 36 is disposed in the first hot pressing plate 24 , and a second electric heating plate (not shown) is disposed in the second hot pressing plate 26 .

[0072] Thus, the workpiece 200 can be heated by the electric heating plate.

[0073] Specifically, the electric heating plate is located inside the hot pressing plate, which can protect the electric heating plate and avoid damage to the electric heating plate.

[0074] One or more electric heating plates may be provided in the hot pressing plate. Figure 5 In the embodiment, a plurality of first electric heating plates 36 are disposed in the first hot pressing plate 24 , and the plurality of first electric heating plates 36 are arranged in an m×n form, which is beneficial to improving the temperature uniformity of the first hot pressing plate 24 , and further improving the heating uniformity of the workpiece 200 .

[0075] The electric heating sheet can provide uniform heat to the workpiece 200 (such as a photovoltaic laminate), melt the glue layer inside the workpiece 200, and facilitate hot pressing and molding thereof.

[0076] In certain embodiments, the first hot press assembly 14 includes a first cooling assembly 38 , the first cooling assembly 38 is connected to the first hot press plate 24 , the first cooling assembly 38 is configured to cool the workpiece 200 through the first hot press plate 24 , and / or;

[0077] The second hot press assembly 16 includes a second cooling assembly 40 , which is connected to the second hot press plate 26 . The second cooling assembly 40 is configured to cool the workpiece 200 through the second hot press plate 26 .

[0078] This is beneficial to the rapid cooling of the workpiece 200 , so that the melted glue inside can be quickly cooled and solidified, thereby achieving the purpose of quickly shaping the workpiece 200 .

[0079] Specifically, in one embodiment, both hot pressing assemblies include cooling assemblies, which can cool the workpiece 200 from both sides of the workpiece 200 at the same time, further improving the cooling speed and uniformity.

[0080] The workpiece 200 may include a glue layer, and the glue layer may connect the layer structure. In one embodiment, the workpiece 200 is a photovoltaic laminate, and the photovoltaic laminate includes a backplane, a glue layer, a battery cell, and a front plate. Before hot pressing, the photovoltaic laminate is a planar stacked structure of the backplane, the glue layer, the battery cell, and the front plate.

[0081] In one embodiment, during hot pressing, the photovoltaic laminate with a planar stacking structure is placed between the first hot pressing plate 24 and the second hot pressing plate 26, and the first hot pressing plate 24 and the second hot pressing plate 26 simultaneously apply thermal pressure to the photovoltaic laminate with a planar stacking structure, so that the photovoltaic laminate with a planar stacking structure forms a photovoltaic laminate with a curved structure. Afterwards, the first cooling assembly 38 and the second cooling assembly 40 can be operated to cool the photovoltaic laminate with a curved structure, so that the adhesive layer is quickly cooled and solidified, so as to achieve the purpose of quickly shaping the photovoltaic laminate with a curved structure. Afterwards, the first hot pressing plate 24 and the second hot pressing plate 26 can be moved away from each other to facilitate the removal of the photovoltaic laminate and send it to the next station.

[0082] In some embodiments, please combine Figure 6 The first cooling assembly 38 includes a first water cooling pipe 42, and the first water cooling pipe 42 is arranged on the surface of the first hot pressing plate 24 away from the second hot pressing plate 26;

[0083] The second cooling assembly 40 includes a second water cooling pipe (not shown). The second water cooling pipe is disposed on a surface of the second hot pressing plate 26 facing away from the first hot pressing plate 24 .

[0084] Therefore, the workpiece 200 can be cooled by water cooling.

[0085] Specifically, after the workpiece 200 with a planar structure is hot-pressed into the workpiece 200 with a curved structure, cold water can be introduced into the first water-cooling pipe 42 and the second level pipe, and the cold water can exchange heat with the workpiece 200 through the water-cooling pipe and the hot-pressing plate to reduce the temperature of the workpiece 200. The cold water becomes hot water after heat exchange, and the hot water flows out of the water-cooling pipe. Under the cooling of the external equipment, it becomes cold water again, and the cold water is introduced into the water-cooling pipe again. In this way, the workpiece 200 after hot pressing is cooled in a cycle, and the cooling efficiency is high.

[0086] Optionally, the first water-cooling pipe 42 is connected to a first water inlet pipe 44 and a first water outlet pipe 46. The first water inlet pipe 44 can be connected to a second water inlet pipe 48 in the shell 12, and the first water outlet pipe 46 can be connected to a second water outlet pipe 50 in the shell 12. External cold water can flow into the first water-cooling pipe 42 through the second water inlet pipe 48 and the first water inlet pipe 44, and hot water after heat exchange can flow out of the shell 12 from the first water-cooling pipe 42 through the first water outlet pipe 46 and the second water outlet pipe 50.

[0087] Optionally, the first hot pressing assembly 14 also includes a first support rod 52, which connects the first water inlet pipe 44 and the first water outlet pipe 46. The first support rod 52 can stably support the first water inlet pipe 44 and the first water outlet pipe 46 to prevent the first water inlet pipe 44 and the first water outlet pipe 46 from deforming and leaking due to excessive water pressure.

[0088] Optionally, the first water cooling tube 42 may be arranged in a Z-shaped direction to increase the contact area between the first water cooling tube 42 and the first hot pressing plate 24 and improve the cooling uniformity of the first hot pressing plate 24. Optionally, the first water cooling tube 42 may form a ring-shaped water channel.

[0089] Optionally, the second water-cooling pipe is connected to a third water inlet pipe 54 and a third water outlet pipe 56. The third water inlet pipe 54 can be connected to a fourth water inlet pipe 58 in the shell 12, and the third water outlet pipe 56 can be connected to a fourth water outlet pipe 60 in the shell 12. External cold water can flow into the second water-cooling pipe through the fourth water inlet pipe 58 and the third water inlet pipe 54, and hot water after heat exchange can flow out of the shell 12 from the second water-cooling pipe through the third water outlet pipe 56 and the fourth water outlet pipe 60.

[0090] Optionally, the second hot pressing assembly 16 also includes a second support rod 62, which connects the third water inlet pipe 54 and the third water outlet pipe 56. The second support rod 62 can stably support the third water inlet pipe 54 and the third water outlet pipe 56 to prevent the third water inlet pipe 54 and the third water outlet pipe 56 from deforming and leaking due to excessive water pressure.

[0091] Optionally, the second water cooling pipes may be arranged in a Z-shaped direction to increase the contact area between the second water cooling pipes and the second hot pressing plate 26 and improve the cooling uniformity of the second hot pressing plate 26. Optionally, the second water cooling pipes may form a ring-shaped water channel.

[0092] In some embodiments, the working chamber 18 is formed with an opening 64 at one side of the housing 12 , and the heat press 100 includes a door 66 rotatably connected to the housing 12 , and the door 66 is used to open and close the opening 64 .

[0093] In this way, it is possible to prevent external foreign matter and dust from entering the working chamber 18 and causing problems such as cracking or poor appearance of the workpiece 200 , and the temperature consistency in the working chamber 18 can also be ensured.

[0094] Specifically, the door body 66 can be connected to the housing 12 via an internal rotating shaft. When the workpiece 200 needs to be hot-pressed, the door body 66 can be opened, and the workpiece 200 can be placed in the working chamber 18 through the opening 64 and located between the first hot-pressing curved surface 20 and the second hot-pressing curved surface 22. After that, the door body 66 can be closed to seal the workpiece 200 cavity, thereby preventing foreign matter and dust from entering the working chamber 18 during the hot-pressing molding of the workpiece 200 (such as a photovoltaic laminate), which may cause problems such as rupture of the workpiece 200 (such as a battery cell) or poor appearance.

[0095] During the hot pressing process, the hot pressing assembly heats the workpiece 200 , and the door body 66 closing the opening 64 can also seal the working chamber 18 to ensure the temperature consistency in the working chamber 18 . Optionally, the door body 66 can be a glass door body 66 .

[0097] Optionally, in other embodiments, the door body 66 may also be integral, and the integral door body 66 is rotatably connected to the upper shell or the lower shell.

[0098] In some embodiments, a control assembly 76 is disposed on the outer side of the housing 12 , and the control assembly 76 is electrically connected to the first hot pressing assembly 14 and the second hot pressing assembly 16 and is configured to control the operation of the first hot pressing assembly 14 and the second hot pressing assembly 16 .

[0099] Thereby, the operating parameters of the hot pressing assembly can be conveniently set.

[0100] Specifically, in one embodiment, the control component 76 may include a touch screen, and the touch screen is provided with touch buttons (including virtual buttons and / or physical buttons), and the user can set the operating parameters of the first hot pressing component 14 and the second hot pressing component 16 through the touch buttons. The operating parameters include but are not limited to the pressure applied by the driving member, the hot pressing speed, the cooling time, the cold water temperature, etc. Optionally, in other embodiments, the control component 76 may include other structural forms of the control component 76, not limited to the touch screen.

[0101] Optionally, the control component 76 can set the operating parameters uniformly and then apply them to the first hot pressing component 14 and the second hot pressing component 16. Optionally, the control component 76 can set the operating parameters separately and then apply them to the first hot pressing component 14 and the second hot pressing component 16. The utility model is not specifically limited.

[0102] The present invention does not specifically limit the position of the control assembly 76. Optionally, in the embodiment shown in the figure, the control assembly 76 is installed on the right outer side of the second shell 70.

[0103] In summary, the heat press 100 of the present invention has at least the following beneficial effects:

[0104] 1. The uniform hot pressing process of two hot pressing components can simultaneously apply thermal pressure to the workpiece 200 to avoid excessive local stress causing the workpiece 200 (such as a battery cell) to break;

[0105] 2. Both hot pressing components use elastic hot pressing plates (such as elastic rubber parts or elastic plastic parts) to provide buffering force to prevent the workpiece 200 (such as battery cells) from breaking due to excessive pressure;

[0106] 3. The door body 66 is used for sealing design. ① When the workpiece 200 is hot pressed, foreign matter and dust from the outside can be prevented from entering the working chamber 18, which may cause the workpiece 200 to break or have a poor appearance. ② The door body 66 can seal the workpiece 200 cavity to ensure the temperature consistency in the working chamber 18;

[0107] 4. The two cooling components use a Z-shaped water cooling pipeline to quickly cool down and solidify the melted glue inside the workpiece 200, so as to achieve the purpose of quickly shaping the workpiece 200;

[0108] 5. The water outlet pipe can quickly flow out hot water, take away the heat, and quickly cool down;

[0109] 6. The support rod can stably support the water inlet and outlet pipes to prevent excessive water pressure from causing pipe deformation and leakage;

[0110] 7. The two hot pressing plates use cylinders to control the up and down strokes. The speed and pressure of the hot pressing plate can be set through the control component 76 of the hot pressing machine 100 to prevent the hot pressing plate from pressing too fast or with too much pressure, which may cause the workpiece 200 (such as a battery cell) to break.
