Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and specifically relates to a core board laminating device. Background Technique

[0002] The core board is a basic component of a circuit board. A common circuit board is composed of one or more core boards, and the core board is composed of a prepreg and copper foil. Then, the copper foil is stably fixed on both the upper and lower sides of the prepreg by heating and curing. During the production and preparation of the core board, wrinkles often occur when the copper foil is connected to the prepreg, and the existence of the wrinkles will affect the quality of the core board.

[0003] For example, the authorized publication number CN108990316B discloses a laminating device for a multi-layer HDI circuit board. The device can prevent the multi-layer HDI circuit board from slipping through the provided anti-slip teeth, and improve the lamination quality of the multi-layer HDI circuit board.

[0004] However, when the device is specifically used, if the copper foil is wrinkled, it cannot level the copper foil in time and fix it flat on the prepreg, thus affecting the processing quality of the circuit board. Content of the Utility Model

[0005] The purpose of the utility model is to provide a core board laminating device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A core board laminating device includes: a processing table, a lifting mechanism, and a leveling mechanism. A processing seat is embedded in the middle position at the upper end of the processing table, and a laminating frame is also installed at the upper end of the processing table; the lifting mechanism is installed on the processing table and is used to drive the leveling mechanism to lift; the leveling mechanism is installed at the lower end of the lifting mechanism and is used to level the wrinkled copper foil. The leveling mechanism includes a leveling smooth groove opened at the lower end of the lifting mechanism. A leveling lead screw is rotatably installed in the leveling smooth groove, and a leveling pressing plate is threadedly sleeved on the leveling lead screw. A leveling motor is also installed at the end of the lifting mechanism, and the output end of the leveling motor is drivingly connected to the shaft end of the leveling lead screw.

[0008] As a preferred solution, a slider is arranged at the upper end of the leveling pressing plate. The slider is threadedly sleeved on the leveling lead screw and is slidably connected to the leveling smooth groove.

[0009] As a preferred solution, the spiral directions on both sides of the leveling lead screw are opposite.

[0010] As a preferred solution, the lifting mechanism includes a lifting electric push rod installed on the laminating frame. The telescopic end of the lifting electric push rod penetrates through the laminating frame and is fixed with a lifting seat. A lifting guide rod is also slidably inserted on the laminating frame, and the lower end of the lifting guide rod is fixedly connected to the upper end of the lifting seat.

[0011] As a preferred solution, the leveling smooth groove is arranged at the lower end of the lifting seat.

[0012] As a preferred solution, a hollow cavity is formed inside the processing seat. An adsorption hole is opened at the upper end of the processing seat, and the adsorption hole communicates with the hollow cavity. A vacuum pump is also installed at the lower end of the processing seat.

[0013] As a preferred solution, a positioning sliding groove is also opened on the processing table, and a positioning mechanism is installed on the processing table. The positioning mechanism includes a positioning plate slidably installed in the positioning sliding groove. A pair of mounting seats are also installed at the lower end of the processing table. A positioning lead screw is rotatably installed between the mounting seats.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The leveling mechanism is driven by the lifting mechanism to move downward. After the leveling mechanism is attached to the copper foil, the leveling motor is started. The leveling lead screw is driven to rotate by the leveling motor, so that the leveling pressing plates on both sides are separated from each other, thereby scraping the copper foil flat. Subsequently, the lifting mechanism drives the leveling mechanism to move upward, and the leveling motor rotates in the reverse direction to move the leveling pressing plates on both sides closer to each other. Then, the prepreg is placed on the copper foil, and the leveling pressing plate is driven to move downward by the lifting mechanism to press the copper foil and the prepreg together, and the lamination work of the core board can be completed, which can effectively improve the processing quality of the core board. The structure of the present utility model is reasonable, and the wrinkled copper foil can be leveled and cured more flatly on the prepreg, thereby improving the quality of the subsequent circuit board and better meeting the use requirements.

The spiral directions on both sides of the leveling lead screw 43 are opposite.

[0024] Working principle of the utility model: During specific use, first place the copper foil on the processing seat 11. Subsequently, drive the flattening mechanism 4 to move downward through the lifting mechanism 3. After the flattening mechanism 4 is in contact with the copper foil, start the flattening motor 41. Drive the flattening lead screw 43 to rotate through the flattening motor 41, so that the flattening pressing plates 42 on both sides are separated from each other, thereby scraping the copper foil flat. Subsequently, the lifting mechanism 3 drives the flattening mechanism 4 to move upward, and the flattening motor 41 rotates in the reverse direction to drive the flattening pressing plates 42 on both sides to approach each other. Subsequently, place the prepreg on the copper foil, drive the flattening pressing plate 42 to move downward through the lifting mechanism 3, and press the copper foil and the prepreg together. Subsequently, place another copper foil on the upper end of the prepreg and repeat the above operations to flatten the copper foil and press it onto the upper end of the prepreg, which can effectively improve the processing quality of the core board and better meet the usage requirements.

[0025] As a further solution, the lifting mechanism 3 includes a lifting electric push rod 31 installed on the laminating frame 13.

The flattening smooth groove 44 is arranged at the lower end of the lifting seat 33.

[0026] The working principle of the lifting mechanism 3 is: drive the lifting seat 33 to move through the lifting electric push rod 31, so as to realize the lifting of the laminating mechanism 4 and facilitate the laminating work of the core board.

[0027] In order to facilitate the fixation of the copper foil, a hollow cavity is opened inside the processing seat 11. An adsorption hole 111 is opened at the upper end of the processing seat 11. The adsorption hole 111 is communicated with the hollow cavity. A vacuum pump 12 is also installed at the lower end of the processing seat 11.

[0028] After the copper foil is placed on the processing seat 11, the vacuum pump 12 pumps air, so that a negative pressure is generated in the hollow cavity, and the copper foil is adsorbed to the processing seat 111 through the adsorption hole 111.
