[0001] The present application relates to the technical field of circuit boards, and in particular to a multi-layer circuit board pressing device. Background Art

[0002] In the electronics industry, multi-layer circuit boards are usually stacked with multiple layers of thin sheet materials (such as glass fiber reinforced resin) with a copper foil layer in the middle. They are pressed together through a high temperature and high pressure process to form a complete multi-layer circuit board structure. During the processing of multi-layer circuit boards, the inner layer board needs to be pressed with the prepreg and copper foil. Currently, a pressing device is often used to complete this task.

[0003] For example, the patent with publication number CN218603740U specifically discloses a multi-layer circuit board pressing device. Through the buffer component design, when the pressure value exceeds the preset pressure value, the pressure sensor sends a signal, and the piston rod and the second spring will drive the bottom plate to drop away from the pressure block, thereby avoiding damage to the circuit board due to excessive pressure and reducing the scrap rate of the circuit board.

[0004] In the above patent, the device prevents the circuit board from being damaged due to excessive pressure by setting a buffer component. However, in the device, after the circuit board is pressed, the multi-layer circuit board will be attached to the plane on the top of the support table, which is not easy to pick up. At this time, additional operating steps or tools may be required to safely remove the circuit board, which increases the complexity of the operation. Therefore, it is necessary to provide a multi-layer circuit board pressing device to solve the above problem.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1 As shown, the present application provides a multilayer circuit board laminating device, including a laminating machine 1, which is arranged in an electronic material processing plant, and a workbench 11 is arranged on the laminating machine 1, and a laminating assembly 2 is arranged on the workbench 11, and the laminating assembly 2 is used to press the inner layer board with the prepreg and the copper foil (hereinafter referred to as the material);

[0025] like Figure 2-Figure 3 As shown, the pressing assembly 2 includes a cover shell 21, which is fixedly mounted on the top of the workbench 11, and a cylinder 22 is fixedly mounted on the cover shell 21. The output end of the cylinder 22 passes through the cover shell 21 and is installed with a connecting plate 23. The interior of the connecting plate 23 is hollow, and the bottom of the connecting plate 23 has a mounting groove 3. A pressing plate 31 is fixedly mounted in the mounting groove 3. The pressing plate 31 is made of copper material with good thermal conductivity and is used for direct contact with the material. The size of the pressing plate 31 is smaller than that of the connecting plate 23. When the pressing plate 31 is placed in the mounting groove 3, the bottom of the pressing plate 31 will protrude from the mounting groove 3.

[0026] At the same time, an air pump 24 is fixedly installed on the top of the connecting plate 23, and the air pump 24 is connected to the inside of the connecting plate 23, and is used to introduce heating gas into the inside of the connecting plate 23 and conduct heat energy to the pressing plate 31, thereby achieving hot pressing;

[0027] At the same time, a card slot (not shown in the figure) is provided at the bottom of the cover shell 21, and a baffle 221 is slidably installed in the card slot. A grabbing portion 222 is provided on the outer side of the baffle 221. When the pressing starts, the grabbing portion 222 is controlled to drive the baffle 221 to move toward the workbench 11, so that the baffle 221 closes the cover shell 21 to prevent the high temperature generated during the pressing from affecting the staff.

[0028] like Figure 2-Figure 5 As shown, a loading assembly 4 is provided on the workbench 11, and the loading assembly 4 includes two sets of slide rails 41, and a placement plate 42 is slidably installed on the slide rails 41, and the placement plate 42 is used to place the material to be pressed, and a handle 431 is provided on one side of the placement plate 42, and the placement plate 42 is suitable for moving on the slide rails 41 driven by the handle 431, and then reaching the bottom of the pressing assembly 2;

[0029] The placement plate 42 has an installation cavity 43 whose size matches the size of the material. A connecting groove 44 is provided inside the installation cavity 43. A spring 45 is fixedly installed in the connecting groove 44. A clamping plate 46 is fixedly installed on the side of the spring 45 away from the connecting groove 44. The size of the clamping plate 46 matches the size of the connecting groove 44. When pressed together, the clamping plate 46 will be completely immersed in the connecting groove 44 under the action of external force. At this time, the bottom of the installation cavity 43 is flat and will not affect the pressing of the material.

[0030] When the pressing starts, the material is first placed inside the connecting groove 44, and then the placing plate 42 is moved to the bottom of the pressing assembly 2, and the air pump 24 and the cylinder 22 are started, so that the pressing plate 31 moves toward the placing plate 42 driven by the cylinder 22, and during the pressing, the pressing plate 31 will sink into the installation cavity 43 and press the material, and at this time, the clamping plate 46 and the spring 45 will be synchronously sunk into the connecting groove 44;

[0031] When the pressing is completed, the pressing plate 31 is away from the installation cavity 43, the force of the spring 45 disappears and drives the clamping plate 46 to rebound, thereby driving one end of the material to tilt up. At this time, the staff can quickly take the material out of the installation cavity 43.

[0032] In summary, the device sets a placement plate 42 so that the material can be quickly taken out of the installation cavity 43 after the pressing is completed. At the same time, the baffle 221 is set to shield the working area during pressing to prevent high temperature from causing harm to the staff, thereby increasing the practicality of the device.

[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
