Description

Technical Field

[0001] This application relates to the field of hot press technology, specifically a hot press for display module circuit boards. Background Technology

[0002] The hot press machine for display module circuit boards is mainly used to press multi-layer circuit board materials (including related components of the display module) together to form a complete circuit board structure. It melts and flows the resin or other adhesives in the circuit board material by heating and applying pressure, thereby filling the gaps between the materials and achieving a strong bond.

[0003] For example, the patent with publication number CN117202537A specifically discloses a flexible circuit board hot pressing mechanism. The mechanism is connected to the heating seat by a lifting screw, and the pressure head is adjusted horizontally by the screw and the base. The first connecting seat and the second connecting seat rotate in different directions through the first pivot and the second pivot. The pressure head is adjusted in different directions by the rotation angle of the first connecting seat and the second connecting seat. The mechanism has a compact structure, is easy to adjust, and has a good fine-tuning effect.

[0004] In the aforementioned patent, the device adjusts the pressure head in different directions by setting multiple sets of connecting seats, allowing for fine-tuning of the mold before pressing. However, since the circuit board needs to be placed in the lower mold first during pressing, and then the upper and lower molds are pressed together by the press, some circuit boards may stick to the lower mold due to pressure. This requires workers to spend more time and effort to manually separate them, which not only reduces production efficiency but may also damage the circuit boards due to improper operation. Therefore, it is necessary to provide a hot press machine for display module circuit boards that can be quickly separated from the mold to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-2 As shown, this application provides a hot press machine for display module circuit boards, including a fixed base 1, which is installed in a display processing plant, and a hot press assembly 2 is provided on the top of the fixed base 1. The hot press assembly 2 is used to perform hot press processing on the circuit boards inside the display.

[0023] like Figures 1-3 As shown, the hot pressing assembly 2 includes a protective cover 21, which is fixedly installed on the top of the fixed base 1. Two sets of presses 22 are arranged inside the protective cover 21. An upper mold 23 is installed on the output end of the press 22. The upper mold 23 is adapted to move under the drive of the press 22 and contact the circuit board. At the same time, multiple sets of slide rails 24 are also arranged on the top of the fixed base 1, and a slider 25 is slidably installed on each set of slide rails 24. A base 3 is installed on the slider 25. The base 3 is adapted to move on the slide rail 24 in cooperation with the slider 25 so as to reach the optimal working position at the bottom of the press 22.

[0024] Meanwhile, a lower mold 31 is detachably installed on the top of the base 3. The top of the lower mold 31 is provided with a receiving groove, and the circuit board to be processed is placed inside the groove. At the same time, multiple sets of support plates 46 are slidably installed on the top of the lower mold 31. The bottom of the support plate 46 is provided with an insertion roller. The support plate 46 is inserted into the lower mold 31 through the insertion roller. A spring is provided between the insertion roller and the lower mold 31. Thus, in the initial state, the support plate 46 is separated from the lower mold 31 by the action of the spring. At this time, the circuit board contacts the support plate 46 and is lifted by the support plate 46.

[0025] In order to keep the circuit board stable during hot pressing, a clamping assembly 4 is also provided on the base 3. The clamping assembly 4 includes two sets of cylinders 41, which are fixedly installed on both sides of the base 3. Push blocks 42 are fixedly installed on the output end of each set of cylinders 41. The push blocks 42 are adapted to contact the lower mold 31 under the drive of the cylinders 41. At the same time, the thickness of the push blocks 42 is greater than the thickness of the lower mold 31, so that the two sets of push blocks 42 can clamp and fix the lower mold 31.

[0026] Meanwhile, a rotating wheel 43 is rotatably mounted on the outer side of the pallet 46, and pressure blocks 44 are provided on both sides of the push block 42 corresponding to the position of the rotating wheel 43. A slope 45 is provided on one side of the pressure block 44, which is suitable for contacting the rotating wheel 43. At the same time, a limiting groove (not shown in the figure) is provided at the bottom of the slope 45. The limiting groove is used to prevent the rotating wheel 43 from deviating when moving, which further ensures the stability and accuracy of the rotating wheel 43 during the movement. Even if it is subjected to external force or after long-term use, the rotating wheel 43 can always keep moving on the limiting groove, avoiding unnecessary deviation or misalignment.

[0027] When it is necessary to clamp and fix the lower mold 31, firstly, the two sets of cylinders 41 are activated, which causes the two sets of push blocks 42 to move toward the lower mold 31. At the same time, since the pressure block 44 extends outward, the inclined surface 45 at the bottom of the pressure block 44 will first contact the rotating wheel 43. At this time, as the pressure block 44 continuously squeezes the rotating wheel 43, the support plate 46 will move toward the lower mold 31. When the support plate 46 contacts the lower mold 31, the push block 42 will also contact the lower mold 31 and clamp and fix it. At this time, the circuit board will be installed in the receiving groove. Then, the lower mold 31 can be placed in the appropriate position for hot pressing through the slide rail 24.

[0028] When the circuit board is finished and needs to be removed from the lower mold 31, the base 3 is first pulled out of the workstation via the slide rail 24. Then, the control cylinder 41 drives the two sets of push blocks 42 to retract. At this time, the rotating wheel 43 will rotate on the pressure block 44, and the support plate 46 will gradually move away from the lower mold 31 under the action of the spring. When the pressure block 44 and the rotating wheel 43 are completely separated, the support plate 46 will drive the circuit board to separate from the lower mold 31. At this time, the operator can quickly remove the circuit board from the support plate 46, reducing the difficulty of operation for the operator and avoiding damage that may be caused by directly hitting or prying the circuit board with external force, thus protecting the integrity and electrical performance of the circuit board.

[0029] In summary, by setting up the clamping component 4, this device can firmly clamp the lower mold 31 when the circuit board is hot-pressed. Furthermore, through the cooperation of the support plate 46 and the spring, the circuit board located on top of it can be more easily separated from the surface of the lower mold 31 after the hot pressing is completed, reducing the difficulty of operation for workers when removing the circuit board.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
