Description

Technical Field

[0001] The utility model relates to the technical field of copper clad laminate production, in particular to a hot pressing device for copper clad laminates. Background Technique

[0002] With the continuous development of technology, copper clad laminates, as key materials in the fields of electronics, communication, automotive, and medical devices, their performance and application requirements are also constantly improving. Copper clad laminates play a crucial role in circuit board manufacturing with their good electrical conductivity, mechanical strength, and thermal stability. Especially in the field of high-frequency circuits, the demand for copper clad laminates is increasing day by day, and higher requirements are also put forward for the performance of their production equipment. In the production process of copper clad laminates, hot pressing is one of the key process steps. Most traditional hot pressing devices directly contact the heating plate with the copper clad laminate for hot pressing operations. Due to high-temperature hot pressing, after the hot pressing is completed, it is easy for the copper clad laminate to adhere to the heating plate, which is not convenient for detachment. At the same time, after the hot pressing is completed, the temperature on the heating plate cannot dissipate quickly, resulting in the risk of scalding for workers when taking materials, and it is easy to cause potential safety hazards. Therefore, a hot pressing device for copper clad laminates needs to be designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hot pressing device for copper clad laminates to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A hot pressing device for copper clad laminates, including a fixing frame, a base, and a lower hot pressing seat. The fixing frame is fixedly installed on the top of the base. The lower hot pressing seat is fixedly connected to the top of the base inside the fixing frame. An upper hot pressing seat is slidably installed between the fixing frames. Heating plates are fixedly installed inside the upper hot pressing seat and the lower hot pressing seat. A hot pressing plate is slidably installed inside the upper hot pressing seat and the lower hot pressing seat. The hot pressing plate is located outside the heating plate. Ventilation grooves are opened inside the hot pressing plate and extend out from both sides of the hot pressing plate. A blower is fixedly installed on the top of the fixing frame. A delivery hose is connected between the air outlet end of the blower and the ventilation grooves.

[0005] Preferably, a protective plate is movably installed at the front end of the fixing frame. A track groove is opened inside the protective plate, and the upper hot pressing seat is slidably installed through a limiting frame in the track groove.

[0006] Preferably, an observation window is opened on the surface of the protective plate, and the protective plate is movably connected to the fixing frame through a hinge.

[0007] Preferably, a thrust spring is fixedly connected between the hot pressing plate and the lower hot pressing seat and the upper hot pressing seat. A heating tube is fixedly installed inside the heating plate.

[0008] Preferably, the upper hot pressing seat is slidably installed between the fixing frames through sliders, and sliding grooves adapted to the sliders are formed in the inner walls of the fixing frames.

[0009] Preferably, a hydraulic push rod is fixedly connected between the fixing frame and the upper hot pressing seat, and support legs are fixedly installed at the bottom of the base.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. By separating the hot pressing plate from the heating plate, when hot pressing the copper clad laminate by extrusion, the hot pressing plate can be brought into contact with the heating plate, so that the heat generated by the heating plate is transferred to the hot pressing plate, and the copper clad laminate can be normally hot pressed. After the hot pressing is completed, the hot pressing plate can be separated from the heating plate, blocking the heat transfer. At the same time, cooperating with a blower to convey external air flow into the ventilation grooves can quickly cool the hot pressing plate, preventing the copper clad laminate from easily adhering to the hot pressing plate and also preventing the staff from being scalded when taking materials.

[0012] 2. Through the mutual cooperation among the protective plate, the track groove and the limiting frame, when the upper hot pressing seat moves downward to close with the lower hot pressing seat, the limiting frame can be synchronously driven to move downward, enabling the limiting frame to slide along the track groove and driving the protective plate to fold and turn downward, covering the front of the hot pressing area, providing protection during the hot pressing process and preventing foreign objects and personnel's limbs from entering the hot pressing area, thus improving the safety effect during hot pressing.

Detailed implementation manners

[0020] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a copper clad laminate hot pressing device proposed by the present utility model includes a fixing frame 1, a base 2 and a lower hot pressing seat 3. A fixing frame 1 is fixedly installed at the top of the base 2, a lower hot pressing seat 3 is fixedly connected to the top of the base 2 inside the fixing frame 1, an upper hot pressing seat 9 is slidably installed between the fixing frames 1, heating plates 4 are fixedly installed inside the upper hot pressing seat 9 and the lower hot pressing seat 3, a hot pressing plate 5 is slidably installed inside the upper hot pressing seat 9 and the lower hot pressing seat 3, the hot pressing plate 5 is located outside the heating plate 4, a ventilation groove 502 is opened inside the hot pressing plate 5, and the ventilation groove 502 extends out of both sides of the hot pressing plate 5. A fan 7 is fixedly installed at the top of the fixing frame 1, and a conveying hose 701 is connected between the air outlet end of the fan 7 and the ventilation groove 502;

[0023] A protection plate 6 is movably installed at the front end of the fixing frame 1. A track groove 601 is opened inside the protection plate 6. The track groove 601 and the upper hot pressing seat 9 are slidably installed through a limiting frame 8. An observation window 602 is opened on the surface of the protection plate 6, and the protection plate 6 and the fixing frame 1 are movably connected through a hinge. Thrust springs 501 are fixedly connected between the hot pressing plate 5 and the lower hot pressing seat 3 and the upper hot pressing seat 9, and heating tubes 401 are fixedly installed inside the heating plate 4.

[0024] The working principle of the copper clad laminate hot pressing device based on Example 1 is: by placing the copper clad laminate to be hot pressed on the hot pressing plate 5 of the lower hot pressing seat 3, and by pushing the upper hot pressing seat 9 to move downward, the hot pressing plate 5 on the upper hot pressing seat 9 can be driven to move downward, so that the upper hot pressing seat 9 and the lower hot pressing seat 3 are closed, so that the hot pressing plate 5 can squeeze the copper clad laminate. When the hot pressing plate 5 is squeezed, it can push the hot pressing plate 5 to move, so that the hot pressing plate 5 can slide in the upper hot pressing seat 9 and the lower hot pressing seat 3, so that the hot pressing plate 5 can be close to the heating plate 4, so that the hot pressing plate 5 can contact the heating plate 4, the hot pressing plate 5 is made of heat-conducting material, and the heating plate 4 is heated by the heating tube 401, so that the heat generated on the heating plate 4 can be transferred to the hot pressing plate 5, so that the hot pressing plate 5 can simultaneously perform hot pressing operations on the front and back sides of the copper clad laminate, thereby improving the hot pressing efficiency;

[0025] When the upper hot pressing seat 9 moves downward, the limiting frame 8 can be synchronously driven to move downward, so that the limiting frame 8 can slide along the track groove 601. The limiting effect of the limiting frame 8 on the track groove 601 can be used to make the limiting frame 8 move downward and drive the protective plate 6 to fold and flip downward. When the upper hot pressing seat 9 and the lower hot pressing seat 3 are closed, the protective plate 6 can be flipped downward to a vertical state, so that the protective plate 6 blocks and isolates the upper hot pressing seat 9 and the lower hot pressing seat 3, so that the protective plate 6 can be blocked in front of the hot pressing area, and can protect the inside during the hot pressing process. It can prevent foreign objects and personnel limbs from entering the hot pressing area during the hot pressing operation to avoid injuries to personnel, thereby effectively improving the safety effect during hot pressing.

[0026] After the hot pressing is completed, the upper hot pressing seat 9 is driven to move upward, so that the upper hot pressing seat 9 can be separated from the lower hot pressing seat 3. The thrust of the thrust spring 501 can push the hot pressing plate 5 to move, so that the hot pressing plate 5 can be separated from the heating plate 4, and the heat transfer can be blocked in time. By starting the fan 7, the external air flow is blown into the conveying hose 701, and the conveying hose 701 can be used to convey the air flow into the ventilation groove 502. The air flow will be guided to both sides of the hot pressing plate 5 along the ventilation groove 502, so that the hot pressing plate 5 can be cooled down relatively quickly, so that the copper clad laminate is not easy to stick to the hot pressing plate 5, and at the same time, it can prevent the staff from being burned when taking materials. The conveying hose 701 is made of flexible material, which can not affect the up and down movement effect of the upper hot pressing seat 9, and can not affect the hot pressing operation of the copper clad laminate.

[0027] Embodiment 2

[0028] like Figure 1 , Figure 3As shown in the figure, a hot pressing device for copper clad laminates proposed by the present utility model, compared with the first embodiment, this embodiment further includes: the upper hot pressing seat 9 is slidably installed between the fixed frame 1 through the slider 902. A chute 101 matching the slider 902 is provided on the inner wall of the fixed frame 1. A hydraulic push rod 901 is fixedly connected between the fixed frame 1 and the upper hot pressing seat 9. The bottom of the base 2 is fixedly installed with support legs 201.

[0029] In this embodiment, as Figure 3 shown, through the slider 902, it can slide up and down along the chute 101, which can enable the upper hot pressing seat 9 to perform stable vertical movement and avoid the situation of the upper hot pressing seat 9 being skewed. By starting the hydraulic push rod 901, power can be provided for the upper hot pressing seat 9, which can conveniently drive the upper hot pressing seat 9 to perform ascending and descending operations; as Figure 1 shown, through the support legs 201, it can conveniently support the base 2.
