[0023] This utility model proposes a pressure head structure 100.

[0024] Please see Figure 1 In one embodiment of this utility model, the pressure head structure 100 is applied to an automatic bonding device. The automatic bonding device includes a negative pressure component and a pressure head driving mechanism. The negative pressure component is disposed on the pressure head driving mechanism. The pressure head structure 100 includes a base 1 and a pressure block 2. The base 1 is connected to the pressure head driving mechanism. The base 1 has a negative pressure channel 11 that penetrates the base 1 and communicates with the negative pressure component. The pressure block 2 is detachably connected to the side of the base 1 facing away from the pressure head driving mechanism. The pressure head has a first through hole 21 that communicates with the negative pressure channel 11.

[0025] In this technical solution, the base 1 is the main body of the pressure head structure 100, which is connected to the pressure head drive mechanism. The base 1 has a negative pressure channel 11, which is connected to the negative pressure component to form a negative pressure environment during the application process. The pressure block 2 is the working part of the pressure head structure 100, which is detachably connected to the side of the base 1 facing away from the pressure head drive mechanism. The pressure block 2 has a first through hole 21, which is connected to the negative pressure channel 11 on the base 1 to ensure that the negative pressure is distributed to the surface of the pressure block 2. Before the bonding operation, install the pressure block 2 onto the base 1, ensuring that the first through hole 21 on the pressure block 2 is aligned with the negative pressure channel 11 on the base 1. Activate the negative pressure component, creating a negative pressure area below the pressure block 2 through the negative pressure channel 11 on the base 1, thus adsorbing the copper foil onto the pressure block 2. The pressure head drive mechanism pushes the pressure block 2, bringing the copper foil adsorbed on the pressure block 2 into contact with the LCD surface. At this point, the negative pressure component stops operating, and the pressure head drive mechanism pushes the pressure block 2 to press the copper foil tightly against the LCD, achieving a tight bond between the copper foil and the LCD. After this, the pressure head drive mechanism separates the pressure block 2 from the LCD with the copper foil bonded, completing the bonding process. The pressure block 2 and the base 1 are detachably connected, either by adhesive or magnetic adsorption. This solution does not impose any restrictions on this. Users can use pressure blocks 2 of appropriate size according to different sizes or models of copper foil. The detachable connection between the pressure block 2 and the base 1 reduces production line downtime and improves production efficiency. The negative pressure component can be a negative pressure pump or a vacuum generator; this solution does not impose any restrictions on this either.

[0026] Specifically, in one embodiment, the pressure block 2 is bonded to the side of the base 1 facing away from the pressure head drive mechanism. The pressure block 2 can be fixed to the base 1 with adhesive, ensuring that the first through hole 21 on the pressure block 2 is aligned with the negative pressure channel 11 on the base 1. This is suitable for applications requiring a stable connection. This bonding method allows the pressure block 2 to be easily disassembled when replacement or maintenance is needed. The detachable connection between the pressure block 2 and the base 1 reduces production line downtime and improves production efficiency. Users can use pressure blocks 2 of appropriate sizes according to different sizes or models of copper foil, improving the flexibility of the production line.

[0027] Please see Figure 2 and Figure 3In one embodiment, the pressure block 2 has multiple through slots 22 along its length, width, and height directions, and all the through slots 22 are interconnected. The first through hole 21 is connected to at least one of the through slots 22. The negative pressure channel 11 is connected to the first through hole 21, and the first through hole 21 is connected to at least one through slot 22, so that negative pressure can be generated in the negative pressure channel 11, the first through hole 21, and the multiple through slots 22. This generates negative pressure at the openings of the multiple through slots 22 in the height direction of the pressure block 2, adsorbing the copper foil. Then, the pressure block 2 presses and attaches the copper foil to the LCD, completing the copper foil attachment. The pressure block 2 can be made of stainless steel, carbon fiber composite material, titanium alloy, ceramic material, magnesium alloy, high-strength plastic, etc., and is usually made of aluminum alloy to ensure its stability and durability. The multiple through slots 22 in the height direction of the pressure block 2 ensure that negative pressure can be evenly formed on the side of the pressure block 2 facing away from the base 1, which helps to evenly adsorb and attach the copper foil and reduce attachment defects.

[0028] In one embodiment, the pressure head structure 100 includes multiple blocking blocks, each of which is used to block the opening of a through groove 22 of the pressure block 2 along its length and width directions. Before the bonding operation, the pressure block 2 is installed on the base 1, ensuring that the first through hole 21 on the pressure block 2 is aligned with the vacuum channel on the base 1. The negative pressure component is activated, and a negative pressure area is formed below the pressure block 2 through the vacuum channel on the base 1, thereby enabling the pressure block 2 to adsorb the copper foil. When the pressure block 2 adsorbs the copper foil, the opening of the through groove 22 of the pressure block 2 along its length and width directions is blocked, so that the negative pressure is concentrated at the opening of the through groove 22 along the height direction of the pressure block 2. The pressure head drive mechanism pushes the pressure block 2, so that the copper foil adsorbed on the pressure block 2 contacts and presses it against the LCD surface, thereby achieving a tight bond between the copper foil and the LCD. By sealing the slots along the length and width of the pressure block 2, the negative pressure is more concentrated, which improves the accuracy of copper foil bonding. The concentration of negative pressure ensures a tight bond between the copper foil and the LCD surface, reducing bonding defects.

[0029] To avoid damaging the copper foil during the mounting process, please refer to [link / reference]. Figure 1 and Figure 2In one embodiment, the pressure head structure 100 includes a soft pad 3, which is connected to the side of the pressure block 2 facing away from the pressure head driving mechanism. The soft pad 3 has multiple second through holes 31, each of which communicates with a through groove 22 along the height direction of the pressure block 2. In this embodiment, the soft pad 3 is a key component of the pressure head structure 100. It is connected to the side of the pressure block 2 facing away from the pressure head driving mechanism. The soft pad 3 is designed to provide additional cushioning and protection. The soft pad 3 has multiple second through holes 31, which communicate with the through groove 22 along the height direction of the pressure block 2, allowing negative pressure to be transmitted from the vacuum channel through the first through hole 21 to the multiple second through holes 31, and then distributed to the entire surface of the soft pad 3. The soft pad 3 is typically made of antistatic silicone, a material with good elasticity and flexibility, which can effectively prevent the generation and accumulation of static electricity, so that the pressure block 2 does not generate too much pressure when pressing and attaching copper foil to the LCD, reducing the risk of product damage.

[0030] More specifically, in another embodiment, the soft pad 3 is detachably connected to the pressure block 2. The user can select a suitable soft pad 3 and pressure block 2 according to the size of the copper foil, detachably connecting the soft pad 3 to the pressure block 2, and ensuring that the first through hole 21 on the pressure block 2 is aligned with the vacuum channel on the base 1. The detachable connection between the soft pad 3 and the pressure block 2 can be achieved through adhesive bonding or magnetic adsorption; this solution does not impose any limitations on this.

[0031] Please see Figure 1 In one embodiment, the base 1 has a connecting post 12 on the side near the pressure head driving mechanism, and the connecting post 12 has the negative pressure channel 11. The connecting post 12 is used to connect to the pipe of the negative pressure component, ensuring that the negative pressure can be transmitted through the pipe to the negative pressure channel 11 in the connecting post 12, and ensuring that the negative pressure is transmitted from the negative pressure channel 11 through the first through hole 21 to the multiple second through holes 31 of the soft pad 3, and then distributed to the entire surface of the pressure block 2, thereby improving the reliability and stability of the pressure block 2 in adsorbing copper foil.

[0032] This utility model also proposes an automatic bonding device, which includes a pressure head driving mechanism, a negative pressure component, and a pressure head structure 100. The specific structure of the pressure head structure 100 is as described in the above embodiments. Since this automatic bonding device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The negative pressure component is disposed on the pressure head driving mechanism; the negative pressure component is connected to the negative pressure channel 11, and the base 1 is connected to the pressure head driving mechanism.

[0033] The pressure head drive mechanism is responsible for driving the pressure head structure 100 to move precisely. It can be a servo motor, stepper motor, or other precision drive device. The negative pressure component is a component used to generate and maintain a negative pressure environment. It can be a negative pressure pump, vacuum pump, or other device capable of generating negative pressure. The negative pressure component is located in the pressure head drive mechanism and communicates with the negative pressure channel 11 in the pressure head structure 100 to ensure that the negative pressure can be evenly distributed on the surface of the pressure block 2. The pressure head structure 100 includes components such as a base 1, a pressure block 2, a soft pad 3, and a block, as well as a vacuum channel for forming a negative pressure environment. The base 1 is connected to the pressure head drive mechanism to ensure that the pressure head structure 100 can move precisely to the target position for the attachment operation. Before applying copper foil, the operator can select appropriate pressure block 2 and soft pad 3 according to the size and shape of the material to be applied. The pressure head structure 100 is installed on the pressure head drive mechanism to ensure a stable connection between the base 1 and the pressure head drive mechanism. The negative pressure component is activated, and a negative pressure area is formed under the pressure block 2 through the negative pressure channel 11 to achieve the adsorption of the material by the pressure block 2. The pressure head drive mechanism pushes the pressure block 2 so that the material adsorbed on the pressure block 2 contacts and presses against the target surface (such as LCD). After the material is tightly adhered to the target surface, the pressure head drive mechanism separates the pressure block 2 from the applied material to complete the application process.

[0034] In one embodiment, the base 1 is detachably connected to the pressure head drive mechanism. This detachable connection allows for quick and easy disassembly of the base 1, facilitating maintenance, cleaning, or replacement of components such as the pressure block 2 or the pad 3, without requiring extensive disassembly of the entire device. It also allows the base 1 to be replaced according to different bonding task requirements, for example, by replacing it with a pressure block 2 adapted to different sizes or shapes of copper foil, thereby improving the flexibility and adaptability of the production line. The detachable connection reduces the time and cost required for maintenance and component replacement. Through modular design, the base 1 and the pressure head drive mechanism can be designed and manufactured independently, simplifying the overall design and manufacturing process. The detachable connection allows the base 1 to be used with various different pressure head drive mechanisms, enhancing the versatility of the equipment and enabling the same base 1 to be used for different production environments or process requirements. On the production line, the detachable connection allows for quick replacement of the base 1 to adapt to different bonding operations, thereby improving overall assembly efficiency. The detachable connection between the base 1 and the pressure head drive mechanism can be achieved using bolts or a snap-fit ​​structure; this solution does not impose any limitations on this.

[0035] Specifically, please refer to Figure 1 and Figure 2In one embodiment, the base 1 has a mounting hole 13. The automatic attachment device includes a fastener that passes through the mounting hole 13 and the pressure head drive mechanism to connect the base 1 to the pressure head drive mechanism. The base 1 is placed in a predetermined position, ensuring that the mounting hole 13 is aligned with the connection point on the pressure head drive mechanism. The fastener is then passed through the pressure head drive mechanism and the mounting hole 13 on the base 1. By rotating the fastener or using other fixing mechanisms, the base 1 is securely fixed to the pressure head drive mechanism. After the base 1 is securely connected, the pressure head drive mechanism can precisely move the pressure head structure 100 to the target position for attachment. When necessary, the base 1 can be quickly disassembled by loosening the fastener for necessary maintenance or replacement of the pressure head structure 100. To facilitate the connection between the pressure block 2 and the base 1, the fastener is not exposed on the base 1 when passing through the mounting hole 13, thus not affecting the installation of the pressure block 2.

[0036] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
