In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid unnecessary details from obscuring the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0026] Embodiment 1

[0027] To solve the defects of small bonding area and insufficient bonding force when bonding products by dispensing between adjacent diaphragms, this embodiment provides a pressing device for dispensing products. Refer to Figures 1-4, specifically including a bracket 1, a pressing mechanism 2, and a support platform 3. The pressing mechanism 2 and the support platform 3 are respectively arranged on the upper and lower parts of the bracket 1. The n-shaped pressure plate 21 in the pressing mechanism 2 moves towards the support platform 3 and forms a vacuum space 5 for pressing the product 4 to be pressed with the support platform 3 in a vacuum state, so that several points of glue between the products 4 to be pressed are heated and melted into a glue film under vacuum and pressure conditions.

[0028] For example, the bracket 1 can be a U-shaped bracket 1, and the support platform 3 is arranged on the concave surface 211 of the U shape. Correspondingly, the pressing mechanism 2 is arranged on the upper part of the U shape and fixed on the two vertical inner walls of the U shape, so that the pressure plate 21 moves up and down linearly along the support platform 3. When moving downward to form a vacuum space 5 with the support platform 3, and moving upward, the product 4 to be pressed can be replaced.

[0029] In the specific real-time process, refer to Figures 1-3 , the pressing mechanism 2 further includes a support cross bar 22, an electric cylinder 23, and a first heating element 24. The two ends of the support cross bar 22 are respectively fixed on the inner side walls of the bracket 1. The electric cylinder 23 is fixed on the support cross bar 22, and the moving end of its telescopic rod 231 is fixedly connected to the n-shaped pressure plate 21. The first heating element 24 is arranged on the concave surface 211 of the n-shaped pressure plate 21 for heating the product 4 to be pressed. That is, in a vacuum state, the first heating element 24 provides heat to the product 4 to be pressed to heat the glue on the product 4 to be pressed to a molten state, and then pressurizes it into a glue film to increase the bonding surface between the upper and lower films of the product 4 to be pressed and improve the bonding degree.

[0030] It should be noted that the working stroke of the electric cylinder 23, the heating temperature and time of the first heating element 24, etc. are all controlled by a controller connected to an external signal to achieve an automatic control function.

[0031] To perform a pressurization process on the product 4 to be pressed in a vacuum environment, refer to Figure 1 , there is a gap 6 between the bottom end surface of the first heating element 24 and the lower end surface of the n-shaped pressure plate 21, so that the upper part of the product 4 to be pressed is accommodated in this gap 6. Relatively, refer to Figures 1-3, the support platform 3 includes an n-shaped support frame 31, a flexible pad 32, and a second heating element 33. Flexible pads 32 are provided at both ends of the n-shaped support frame 31. The second heating element 33 is laid flat along the upper end surface of the n-shaped support frame 31 for carrying the product 4 to be pressed. The second heating element 33 is located between the two flexible pads 32, so that a U-shaped space is formed between the flexible pad 32 and the second heating element 33 to form a vacuum space 5 for pressing the product 4 to be pressed with the gap 6. That is, during the operation of the electric cylinder 23, the space formed when the pressure plate 21 moves downward and abuts against the flexible pad 32 can be the vacuum space 5. At this time, vacuum is pumped to form the vacuum space 5, but the pressure plate 21 does not apply pressure to the flexible pad 32. The first heating element 24 and the second heating element 33 are turned on to heat the dispensing glue in the product 4 to a molten state, and then the pressure plate 21 continues to press down to compress the flexible pad 32. During this process, the product 4 to be pressed is compressed, and the molten dispensing glue forms a glue film, thus completing the pressing of the product 4 to be pressed.

[0032] For example, the flexible pad 32 is a silicone pad. Before pressing, the flexible pad 32 abuts against the pressure plate 21. At this time, the flexible pad 32 does not deform; when the dispensing glue in the product 4 to be pressed is heated to a molten state, the pressure plate 21 continues to press down, causing the flexible pad 32 to deform. At this time, under the action of pressure, the molten dispensing glue in the product 4 to be pressed is pressed into a glue film to complete the pressing operation of the product 4 to be pressed.

[0033] More specifically, referring to Figures 1-3 , the support platform 3 further includes a vacuum pump 34. The vacuum pump 34 is provided inside the n-shaped support frame 31, and the suction pipe 341 of the vacuum pump 34 sequentially passes through the n-shaped support frame 31 and the second heating element 33 to communicate with the vacuum space 5, so that the air between the upper and lower film surfaces of the product 4 to be pressed is evacuated without bubbles. At the same time, due to the existence of air pressure, the pressing mechanism 2 and the support platform 3 can be tightly pressed together. For example, the vacuum pump 34 can be controlled by a controller to achieve automatic control.

[0034] Perforations (not shown in the figure) are provided on the second heating element 33, so that the suction pipe 341 penetrates into the perforations, and the suction end of the suction pipe 341 is flush with the upper end surface of the perforation. To facilitate air intake and evacuation, further, after the product to be pressurized is placed on the support platform 3, there is a gap around the support platform 3, and the perforations are provided at the gap.

[0035] Furthermore, to improve the service life of the equipment and facilitate replacement, referring to Figures 1-3, one end of the first heating element 24 facing away from the n-type pressure plate 21 is provided with a first partition 25; one end of the second heating element 33 facing away from the n-type support frame 31 is provided with a second partition 35, so that while the first partition 25 and the second partition 35 are respectively in pressure contact with the upper end face and the lower end face of the product 4 to be pressed, heat is transferred. The first partition 25 and the second partition 35 are structures in direct contact with the product 4 to be pressed. Therefore, they are vulnerable parts of the entire device, and are convenient to replace and have low cost.

[0036] For example, the product 4 to be pressed includes an upper film 41, a lower film 42, and a dispensing 43 that bonds the upper film 41 and the lower film 42.

[0037] The present utility model is implemented as follows:

[0038] 1. Place the product 4 to be pressed on the second partition 35, and expose the suction end of the suction pipeline 341 to the product 4 to be pressed to facilitate the extraction of air;

[0039] 2. Turn on the pressing mechanism 2 so that the pressure plate 21 moves towards the support platform 3 until it abuts and seals against the flexible pad 32, but the flexible pad 32 does not deform;

[0040] 3. Turn on the vacuum pump 34 so that a vacuum space 5 is formed between the pressing mechanism 2 and the support platform 3;

[0041] 4. The first heating element 24 and the second heating element 33 start to work. At this time, heat is transferred to the upper and lower end faces of the product 4 to be pressed through the first partition 25 and the second partition 35 respectively, and then the dispensing in the product 4 to be pressed is heated so that the dispensing is heated to a molten state;

[0042] 5. Turn on the pressure plate 21 to continue pressing down so that the flexible pad 32 undergoes a certain deformation, and then the dispensing in the molten state is pressed into a glue film;

[0043] 6. Complete the pressing operation of the product 4 to be pressed.

[0044] In this embodiment, according to actual requirements (for example, the size of the device or the size of the product to be pressed, etc.), one or several products 4 to be pressed can be pressed at the same time.

[0045] It should be noted that in the above embodiments, the descriptions of each embodiment have their own emphases. For parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0046] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments as well as all changes and modifications that fall within the scope of the present invention.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
