Description

Technical Field

[0001] This application relates to the field of hot-press bonding technology, and in particular to a back support device and a back support device. Background Technology

[0002] The hot-press bonding process, also known as the local pressing process, in display module technology refers to bonding a layer of bonding material to glass or a flexible substrate by reacting anisotropic conductive film (ACF) under specific temperature and pressure conditions. This bonding process achieves electrical conductivity between the bonding material layer and the glass or flexible substrate. Examples of bonding material layers include integrated circuits (ICs), chip-on-film (COF) films, and flexible printed circuit boards (FPCs). Glass examples include liquid crystal displays (LCDs) or touchscreens. Flexible substrates include organic light-emitting diode (OLED) flexible screens, touch layers, or films.

[0003] With the development of products and new technologies, there are more and more flexible screen products. Flexible screens are mostly made of film material, which is easily burned and deformed when heated, especially the screen encapsulation (Chip On Plastic, COP) process or panel coating (Film on Panel, FOP) process.

[0004] Specifically, the bonding head is a key component used in the bonding process in the electronics manufacturing industry, especially in the production of flexible screens. However, during bonding, the bonding head rapidly conducts high temperatures to the product, which can easily cause burns to OLED screen parts that are close to the bonding head, or burns to the lower polarizer of LCD screens. Utility Model Content

[0005] Therefore, it is necessary to provide a pressure back support device and a pressure device.

[0006] One embodiment of this application is a back support device, which includes a back support pressure head and a cooling pipe;

[0007] The back support head is used to support the pressing part of the product to be processed, so as to cooperate with the hot press head to hot press the pressing part of the product to be processed.

[0008] The cooling pipe is disposed adjacent to the back support pressure head so that the cooling pipe is adjacent to the pressing part;

[0009] The cooling pipe is provided with a pipe body and a cooling pipe connector. The pipe body is provided with an air outlet, which faces the product to be processed, so that the cooling pipe has a cooling air direction towards the product to be processed.

[0011] The aforementioned back-support device, through the cooperation of the back-support pressure head and cooling pipe, serves two main purposes. First, during the back-support pressing process, it outputs cooling gas towards the product being processed through the air outlet, and the air outlet of the cooling pipe is also directed towards the product, forming a specific cooling airflow. This ensures that the cooling gas acts evenly on the product near the pressing section, preventing localized overheating and ensuring that the main body of the product receives uniform cooling. Second, during the back-support pressing process, when the hot pressure head is in contact with the pressing section of the product, it effectively prevents rapid heat conduction to other parts of the product besides the pressing section, thus protecting the product. This makes it less likely for OLED screens or LCD screens near the pressure head to be burned. Third, the cooling pipe has a relatively simple structure, facilitating installation and connection to an external cooling gas supply system. Furthermore, routine maintenance makes it easier to inspect, clean, and replace the cooling pipe, ensuring the normal operation of the back-support device, reducing the risk of production interruptions due to equipment failure or improper maintenance, and further guaranteeing production continuity and stability.

[0015] In some embodiments, the back support device further includes a heating base that abuts against the back support pressure head and is used to conduct heat to the back support pressure head.

[0016] In some embodiments, the back support pressure head is disposed on the heating base; and / or,

[0017] The cooling pipe is mounted on the heating base.

[0018] In some embodiments, the back support device further includes a heating element that passes through the heating base for conductive heating of the heating base.

[0021] The back support device also includes a base, the heating seat is disposed on the base, and the cooling pipe is disposed on the heating seat or the base via a support.

[0022] In some embodiments, the back support head is provided with a ramp near the cooling pipe, the ramp being used to deflect the cooling gas in the cooling airflow direction.

[0023] In some embodiments, a self-pressing device includes a hot press head, a support platform, and a self-pressing back support device as described in any embodiment;

[0024] The support platform is used to support the main body of the product to be processed, and there is a gap between the support platform and the hot press head;

[0025] The hot press head is used to press the pressing part of the product to be processed onto the back support press head of the back support device.

[0044] This application discloses a back-press device and a pressing device, which includes some or all of the technical features of the following embodiments; that is, the back-press device and the pressing device include some or all of the following structures. In one embodiment of this application, a back-press device includes a back-press head and a cooling pipe; the back-press head is used to support the pressing part of the product to be processed, so as to cooperate with the hot pressing head to hot press the pressing part of the product to be processed; the cooling pipe is disposed adjacent to the back-press head, so that the cooling pipe is adjacent to the pressing part; the cooling pipe has a pipe body and a cooling pipe connector, the pipe body has an air outlet, and the air outlet faces the product to be processed, so that the cooling pipe has a cooling air direction towards the product to be processed; the cooling pipe connector is connected to the pipe body for inputting cooling gas and outputting the cooling gas through the air outlet. The aforementioned back-support device, through the cooperation of the back-support pressure head and cooling pipe, serves two main purposes. First, during the back-support pressing process, it outputs cooling gas towards the product being processed through the air outlet, and the air outlet of the cooling pipe is also directed towards the product, forming a specific cooling airflow. This ensures that the cooling gas acts evenly on the product near the pressing section, preventing localized overheating and ensuring that the main body of the product receives uniform cooling. Second, during the back-support pressing process, when the hot pressure head is in contact with the pressing section of the product, it effectively prevents rapid heat conduction to other parts of the product besides the pressing section, thus protecting the product. This makes it less likely for OLED screens or LCD screens near the pressure head to be burned. Third, the cooling pipe has a relatively simple structure, facilitating installation and connection to an external cooling gas supply system. Furthermore, routine maintenance makes it easier to inspect, clean, and replace the cooling pipe, ensuring the normal operation of the back-support device, reducing the risk of production interruptions due to equipment failure or improper maintenance, and further guaranteeing production continuity and stability. The following is combined Figures 1 to 10 The back support device and the pressure equipment described herein will be described in detail.

[0045] In some embodiments, a pressure device 500, such as... Figure 1 and Figure 2 As shown, it includes a hot press head 200, a support platform 400, and the back support device 100 described in any embodiment herein; combined with Figure 3 and Figure 4The support platform 400 supports the main body 302 of the product to be processed 300, and the support platform 400 and the hot press head 200 have a gap 401. The hot press head 200 presses the pressing part 301 of the product to be processed 300 onto the back support press head 105 of the back support device 100. The cooling airflow direction 111 of the cooling pipe 108 of the back support device 100 is towards the gap 401. In this embodiment, the product to be processed 300 includes a main body 302, a middle part 303, and a pressing part 301. The middle part 303 is located between the main body 302 and the pressing part 301, and the middle part 303 is located in the gap 401. The cooling airflow direction 111 of the cooling pipe 108 is towards the middle part 303. This structural design, with the cooling pipe 108 oriented towards the product 300 to be processed and forming a specific cooling airflow 111, allows the cooling gas to act evenly on the product 300 next to the pressing part 301, avoiding local overheating of the product 300 to be processed and ensuring that the main body of the product 300 to be processed can uniformly achieve the required cooling effect. In addition, since the pressing device 500 adopts the pressing back support device 100 described in any embodiment, the pressing device 500 also has the beneficial technical effects of the pressing back support device 100, which will not be elaborated here.

[0046] In some embodiments, a back support device 100, such as Figure 5 and Figure 6 As shown, it includes a back support head 105 and a cooling pipe 108; combined with Figure 3 and Figure 4 The back support pressure head 105 is used to support the pressing part 301 of the product to be processed 300, so as to cooperate with the hot pressure head 200 to hot press the pressing part 301 of the product to be processed 300; the cooling pipe 108 is disposed adjacent to the back support pressure head 105 so that the cooling pipe 108 is adjacent to the pressing part 301; combined Figure 8 and Figure 10The cooling pipe 108 is provided with a pipe body 113 and a cooling pipe connector 110. The pipe body 113 is provided with an air outlet 115, which faces the product to be processed 300, so that the cooling pipe 108 has a cooling airflow direction 111 towards the product to be processed 300. The cooling pipe connector 110 is connected to the pipe body 113 for inputting cooling gas and outputting the cooling gas through the air outlet 115. This structural design, through the cooperation of the back support pressure head 105 and the cooling pipe 108, allows for two main benefits. First, during the pressing process, cooling gas is output towards the product 300 through the air outlet 115, and through the air outlet 115 of the cooling pipe 108, it is directed towards the product 300, forming a specific cooling airflow 111. This ensures that the cooling gas acts evenly on the product 300 next to the pressing part 301, preventing localized overheating and ensuring that the main body of the product 300 achieves the required cooling effect uniformly. Second, during the pressing process, when the hot pressure head 200 is in contact with the pressing part 301 of the product 300, it effectively... This avoids the rapid conduction of high temperatures to other parts of the product 300 except for the pressing part 301 due to contact, thus protecting the product 300. This prevents the OLED screen area, which is closer to the pressing head, from being burned, or the LCD screen area, which is closer to the pressing head, from being burned on the lower polarizer. Furthermore, the cooling pipe 108 has a relatively simple structure, which facilitates installation and connection to an external cooling gas supply system. In daily maintenance, it is also easier to inspect, clean, and replace the cooling pipe 108, ensuring the normal operation of this back support device 100, reducing the risk of production interruption due to equipment failure or improper maintenance, and further ensuring the continuity and stability of production.

[0047] As an example, the back-support device 100 mainly includes two key components: a back-support pressure head 105 and a cooling pipe 108. The back-support pressure head 105 plays a crucial role, precisely supporting the pressing portion 301 of the product 300 to be processed. When the hot pressing head 200 performs hot pressing on the product 300, the back-support pressure head 105 closely cooperates with the hot pressing head 200, ensuring the stability and accuracy of the pressing process and providing a strong guarantee for producing high-quality products. Meanwhile, the cooling pipe 108 is cleverly positioned close to the back-support pressure head 105, so that the cooling pipe 108 is adjacent to the pressing portion 301 of the product 300 to be processed, thereby achieving a rapid and effective cooling effect. Furthermore, the cooling pipe 108 itself has a unique structural design. The cooling pipe 108 includes a pipe body 113 and a cooling pipe connector 110. The pipe body 113 is provided with an air outlet 115, which is also carefully designed so that its orientation is exactly facing the product 300 to be processed. This allows the cooling gas output from the cooling pipe 108 to act directly on the product 300 to be processed in a specific cooling airflow direction 111, thereby achieving the purpose of rapidly cooling the pressing part 301. In this embodiment, the cooling pipe connector 110 is tightly connected to the pipe body 113. The main function of the cooling pipe connector 110 is to input cooling gas. After the cooling gas enters the pipe body 113 through the cooling pipe connector 110, it is smoothly output from the air outlet 115 and evenly sprayed onto the pressing part 301 of the product 300 to be processed. This ingenious design effectively protects the other parts of the product to be processed 300, except for the pressing part 301, during the hot pressing process, preventing them from being burned by high temperatures. This ensures the integrity and quality of the product to be processed 300, greatly reduces the defect rate in the production process, and improves production efficiency and economic benefits.

[0048] In each embodiment, such as Figure 3 and Figure 4 As shown, the back support head 105 supports the pressing portion 301 of the product to be processed 300, so as to cooperate with the hot press head 200 to hot press the pressing portion 301 of the product to be processed 300. In this embodiment, the back support device 100 further includes a heating base 102, which abuts against the back support head 105 and is used to conduct heat to the back support head 105. In some embodiments, the back support head 105 is disposed on the heating base 102; in some embodiments, the cooling pipe 108 is disposed on the heating base 102; in other embodiments, the cooling pipe 108 may also be disposed on the back support head 105, indirectly disposed on the heating base 102 through the back support head 105. With this structural design, heat can be generated by the heating base 102, and the heat can be transferred to the back support head 105 by conduction.

[0049] In some of these embodiments, such as Figure 5 and Figure 6 As shown, the back support device 100 further includes a heating element 103, which passes through the heating base 102 and is used to heat the heating base 102 by conduction. Figure 7 and Figure 8 In this embodiment, the back support device 100 further includes a thermocouple 104, which abuts against the heating element 103 or the heating base 102. As an example, the back support device 100 also includes a limiting block 106, which limits the relative position of the back support head 105 and the heating base 102. In this embodiment, the back support device 100 also includes a base 101, on which the heating base 102 is disposed, and the cooling element 108 is disposed on the heating base 102 or the base 101 via a support 107. This structural design facilitates the overall installation, movement, and storage of the back support device 100; allows the thermocouple 104 to determine whether the heating element 103 is functioning properly; and enables the limiting block 106 to maintain the position of the back support head 105.

[0050] In some of these embodiments, such as Figure 8 and Figure 9 As shown, the back support pressure head 105 has a ramp surface 112 near the cooling pipe 108. The ramp surface 112 is used to avoid the cooling gas in the cooling airflow direction 111. In this embodiment, the back support pressure head 105 also has a back support boss 116, which cooperates with the hot pressure head 200 to hot-press the pressing part 301 of the product to be processed 300. As an example, the shape of the back support boss 116 is adapted to the shape of the hot pressure head 200 and to the shape or design requirements of the pressing part 301 of the product to be processed 300. This structural design, on the one hand, allows the cooling gas to be avoided by the ramp surface 112, so that the cooling gas output from the air outlet 115 can be as close as possible to the pressing part 301 of the product to be processed 300 when it is blown towards the middle part 303 of the product to be processed, thereby better protecting the main body of the product to be processed 300. On the other hand, the design of the back support boss 116 ensures the best possible hot pressing effect on the pressing part 301 of the product to be processed 300.

[0051] In each embodiment, such as Figure 8 and Figure 10As shown, the cooling pipe 108 is disposed adjacent to the back support pressure head 105, so that the cooling pipe 108 is adjacent to the pressing part 301; the cooling pipe 108 has a pipe body 113 and a cooling pipe connector 110, the pipe body 113 has an air outlet 115, the air outlet 115 faces the product to be processed 300, so that the cooling pipe 108 has a cooling airflow direction 111 towards the product to be processed 300; the cooling pipe connector 110 is connected to the pipe body 113 for inputting cooling gas and outputting the cooling gas through the air outlet 115. In this embodiment, the plurality of air outlets 115 are arranged in a straight line. In other embodiments, the air outlets 115 are straight. Exemplarily, the straight shape of the air outlets 115 themselves or their straight arrangement are used to output cooling gas as evenly as possible to the middle part 303 of the product to be processed 300, so as to protect the main body 302 of the product to be processed 300 as much as possible.

[0052] In some embodiments, the back support device 100 further includes a support 107, and the tube body 113 is rotatably connected to the support 107. In some embodiments, the cooling tube 108 is also provided with a pointer 109, which is connected to the tube body 113 and is aligned with the position of the air outlet 115, for indicating the cooling airflow direction 111. As an example, the back support device 100 further includes a support 107, and the tube body 113 is rotatably connected to the support 107; and the cooling tube 108 is also provided with a pointer 109, which is connected to the tube body 113 and is aligned with the position of the air outlet 115, for indicating the cooling airflow direction 111. Other embodiments follow the same principle and will not be described in detail. This structural design facilitates the overall assembly of the cooling pipe 108 and allows for accurate determination of the cooling airflow direction 111 of the air outlet 115 of the cooling pipe 108 via the pointer 109, which can be adjusted by rotating the pipe body 113, making the pressure back support device 100 and its cooling pipe 108 easy to use.

[0053] The following will continue to combine Figures 1 to 10The following is an example illustrating the back support device 100. In some embodiments, the back support device 100 has a cooling function, and therefore can also be referred to as a back support device 100 with a cooling function. Its main components are described below. A heating base 102 is fixed above a base 101. The base 101 is made of heat-insulating ceramic material to prevent the heat from the heating base 102 from being largely conducted away by the base. A heating element 103 and a thermocouple 104 are respectively installed inside the heating base 102 through holes on its side. The heating element 103 provides heating when connected to a power source, and the thermocouple 104 can monitor the heating base 102 or the heating element 103 in real time. A back support head 105 is fixed above the heating base 102, with both ends limited by limiting blocks 106. Heat is conducted from the heating base 102 to the back support head 105, and then to the product to be processed. 300; A row of 1mm diameter holes are densely distributed on the cooling pipe 108 as air outlets 115, and the two ends are fixed by two supports 107 and installed on the side of the heating base 102. The supports 107 are made of heat insulation material. A pointer 109 is fixed at the right end of the cooling pipe 108 and the inner hole of the cooling pipe 108 is blocked. The pointer 109 and the cooling pipe joint 110 are fixed at the left end of the cooling pipe 108, so that the cooling pipe joint 110 is connected to the inner hole of the cooling pipe 108. The other end of the cooling pipe joint 110 is connected to the cooling gas, so as to achieve the purpose of conveying gas to cool the product 300 to be processed during pressing.

[0054] As an example, the back support pressure head 105 adopts a sloping cooling groove design in the middle, which facilitates the air blown out by the side cooling pipe 108 to directly reach the product 300 to be processed near the pressure head. As an example, pointers 109 are fixed at both ends of the cooling pipe 108, and the direction of the needle tip of the pointer 109 is consistent with the direction of the air hole on the cooling pipe 108, that is, the air outlet. Therefore, the direction and position pointed to by the needle tip of the pointer 109 is the position aligned with the air hole of the cooling pipe 108, which is the immediate cooling position. Since the product 300 to be processed will be directly above the cooling pipe 108 during hot pressing, blocking the personnel from observing the direction of the air blown by the cooling pipe 108, the direction of the cooling air blown by the pointer 109 can be easily determined by the direction of the needle tip. The direction of the cooling air blown by the cooling pipe 108 can be adjusted by adjusting the angle of the pointer 109 on the cooling pipe 108. In various embodiments, the cooling pipe can be replaced by other air blowing cooling mechanisms, the small round holes evenly distributed on the cooling pipe can be replaced by other grooves or holes, and the air blowing pointer can be replaced by other indicating mechanisms.

[0055] In this embodiment, the back support device 100 with cooling function avoids the rapid conduction of high temperature from the pressure head to the product 300 during the pressing process. This prevents OLED screen parts close to the pressure head from being burned by the cooling function, or the polarizer of the LCD screen from being burned during the pressing process. Its working principle is illustrated below. During the pressing process, the product 300 is placed above the back support pressure head 108 by the movement of the support platform 400. At this time, the hot pressure head 200 presses down on the product 300. Since the hot pressure head 200 and the back support pressure head 108 provide heat to the product 300, the bonding area of ​​the product 300 receives a large amount of heat, which is conducted to the lower temperature area behind the product 300. At this time, the cooling pipe 108 generates a large amount of gas, which is blown towards the bottom of the bonding area near the product 300. The gas carries away the heat from the product 300, maintaining it at a safe temperature that is acceptable to the product 300, preventing damage and deformation or burns.

[0056] In some embodiments, a back support device 100 with a cooling function is such as... Figure 5 and Figure 8 As shown, it includes a base 101, a heating element 102, a heating tube 103, a thermocouple 104, a back support head 105, a limiting block 106, a support 107, a cooling tube 108, a pointer 109, and a cooling tube connector 110. The base 101 is made of heat-insulating ceramic material. The heating element 102 is fixed above the base 101. The heating tube 103 is installed inside the heating element 102 to provide heat. The thermocouple 104 is installed inside the heating element 102 for real-time temperature monitoring. The back support head 105 is fixed above the heating element 102 to conduct heat to the product 30 to be processed. 0; Limiting blocks 106 are disposed at both ends of the back support pressure head 105 to limit the back support pressure head 105; Cooling pipe 108 is fixed to the side of the heating base 102, and has dense holes with a diameter of 1mm as air outlets 115 for conveying cooling gas to the middle part 303 of the product to be processed 300; Support 107 is used to fix both ends of the cooling pipe 108 and is made of heat insulation material; Pointer 109 is fixed at both ends of the cooling pipe 108 to indicate the blowing direction of the cooling gas; Cooling pipe connector 110 is fixed to the left end of the cooling pipe 108 for inputting cooling gas to the air outlet 115.

[0057] As an example, the back support pressure head 105 adopts a sloping cooling groove design in the middle, forming a sloping surface 112, so that the gas blown out by the side cooling pipe 108 can be directly blown to the position of the product 300 to be processed near the pressure head. As an example, the tip of the pointer 109 is consistent with the air hole on the cooling pipe 108, and the cooling air blowing direction of the cooling pipe 108 can be adjusted by adjusting the angle of the pointer 109. As an example, the cooling pipe 108 can be replaced by other air blowing cooling mechanisms, the small round hole on the cooling pipe 108 can be replaced by other grooves or holes, and the air blowing pointer 109 can be replaced by other indicating mechanisms. As an example, the pointer 109 is fixed to the right end of the cooling pipe 108 and the inner hole of the cooling pipe 108 is blocked, and the other end of the cooling pipe connector 110 is connected to the cooling gas to achieve the purpose of delivering gas to cool the product 300 to be processed during pressing. As an example, the heating base 102 is made of heat-insulating ceramic material to prevent the temperature of the heating base 102 from being largely conducted away by the base 101. As an example, the thermocouple 104 can monitor the temperature of the heating base 102 in real time to ensure that the temperature of the heating base 102 is controlled within a preset range. As an example, the working principle of the cooling pipe 108 is as follows: during pressing, the cooling pipe 108 generates a large amount of gas that blows towards the bottom of the bonding area near the product to be processed 300, carrying away the heat from the product to be processed 300 and maintaining it at a safe temperature acceptable to the product to be processed 300, without damaging the product to be processed 300 or causing deformation or burns. As an example, the pressure back support device 100 avoids the pressure head rapidly conducting high temperatures to the product to be processed 300 during pressing, making it less likely for the OLED screen area close to the pressure head to be burned through cooling, or for the polarizer of the LCD screen to be burned during pressing. As an example, the working process of the back support device 100 is as follows: During the pressing process, the product to be processed 300 places the pressing area above the back support head 105 through the movement of the support platform. At this time, the hot pressing head presses down on the product to be processed 300. Since the hot pressing head and the back support head 105 provide heat to the product to be processed 300 respectively, the binding area of ​​the product to be processed 300 will receive a large amount of heat and the heat will be conducted to the low-temperature area behind the product to be processed 300. At this time, the cooling pipe 108 works to generate a large amount of gas and blows it towards the bottom of the binding area of ​​the product to be processed 300, carrying away the heat of the product to be processed 300 and maintaining it at a safe temperature that is acceptable to the product to be processed 300, without damaging the product to be processed 300 or causing deformation or burns.
