Description

Technical Field

[0001] This utility model relates to the field of multilayer PCB board production, specifically a PCB multilayer board laminating machine. Background Technology

[0002] A PCB (Printed Circuit Board) is a multilayer printed circuit board with two or more layers. It consists of connecting wires on several insulating substrates and pads for assembling and soldering electronic components. It serves both to conduct the circuitry between layers and to insulate the circuitry between them. During the production of a multilayer PCB, PP film, aluminum foil, and inner circuit boards are bonded together into a single unit under specific temperature and pressure conditions.

[0003] Current PCB multilayer board laminating machines, as described in patent CN214852080U, include a frame with a laminating operation chamber at the top. The laminating operation chamber comprises an operating table, side plates symmetrically arranged on both sides of the operating table, and a rear plate at the rear of the operating table. A lower pressure plate is provided at the top of the operating table and can slide back and forth on the operating table. An arched frame is provided at the top of the frame, and a lifting mechanism and an upper pressure plate connected to the lifting mechanism are provided on the arched frame. An electric heating device is provided inside the lower and upper pressure plates. A limiting block is provided at the rear of the lower pressure plate, and a brush roller is also provided on the limiting block.

[0004] Regarding the aforementioned related technologies, the inventors believe that by setting up a set of pressure plates to support the PP film, aluminum foil, and inner circuit board to be pressed, it is necessary to wait for the previous set of PP film, aluminum foil, and inner circuit board to be pressed and removed before the next set of PP film, aluminum foil, and inner circuit board to be pressed can be placed, resulting in low pressing efficiency of PP film, aluminum foil, and inner circuit board. Utility Model Content

[0005] The purpose of this invention is to provide a PCB multilayer board laminating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

This effectively improves the pressing efficiency of PP film, aluminum foil, and inner circuit board. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4A PCB multilayer board laminating machine includes a steering mechanism 1. The steering mechanism 1 includes a base 101, and a stepper motor 102 is fixedly connected to the bottom of the base 101. A rotating seat 103 is fixedly connected to the output end of the stepper motor 102. The stepper motor 102 is configured to drive the rotating seat 103 to rotate during startup. Multiple columns 106 are fixedly connected in a circular array to the bottom of the rotating seat 103. Each set of columns 106 has a first ball bearing 107 movably connected to its bottom, which contacts the top of the base 101. The columns 106 and the first ball bearing 107 provide auxiliary support for the rotating seat 103.

[0025] The top of the rotating base 103 is symmetrically and detachably connected to pressure seats 104. Both pressure seats 104 have grooves 105 on their tops. These grooves 105 are used to limit the movement of the PP film, aluminum foil, and inner circuit board to be pressed, reducing the probability of misalignment. The bottom of both pressure seats 104 is symmetrically fixed with inserts 113. The top sides of the rotating base 103 have symmetrically formed slots 114 that fit the inserts 113. Each set of inserts 113 is inserted into its respective slot 114. The insertion of the inserts 113 into the slots 114 limits the movement of the pressure seats 104.

[0026] Rotating base 103 has rotating shafts 115 rotatably connected to both sides. Traction ropes 118 are symmetrically fixed to the outer side of rotating shafts 115. Each traction rope 118 has a limiting block 116 fixedly connected to the end away from rotating shaft 115. The limiting block 116 is slidably connected to rotating base 103. The rotating shaft 115 is designed to wind and unwind the traction ropes 118 during rotation, thereby pulling the limiting block 116 to slide. Each set of insert blocks 113 has a limiting groove 119 on its outer side. Each set of limiting blocks 116 is inserted into the interior of the limiting groove 119. By inserting the limiting block 116 into the limiting groove 119, the insert block 113 can be limited, thereby fixing the pressure base 104.

[0027] Each set of limiting blocks 116 has a first spring 117 fixedly connected to the side near the rotating shaft 115. The end of each first spring 117 away from the limiting block 116 is fixedly connected to the rotating seat 103. The first spring 117 is designed to use its elasticity to push the limiting block 116 into the limiting groove 119, thereby reducing the probability of the limiting block 116 dislodging from the limiting groove 119. Both sets of grooves 105 have matching support plates 112 slidably connected inside. The bottom of both sets of support plates 112 is fixedly connected to a sliding post 110, which penetrates the rotating seat 103. The support plates 112 provide support for the PP film, aluminum foil, and inner circuit board to be pressed inside the grooves 105.

[0028] A support ring 108 is fixedly connected to the top of the base 101. The top of the support ring 108 is symmetrically provided with inclined grooves 109. The bottom of each of the two sets of sliding columns 110 is movably connected with a second ball bearing 111. Both sets of second ball bearings 111 are in contact with the top of the support ring 108. The sliding columns 110 are designed to rotate synchronously with the rotating seat 103, so that the second ball bearings 111 can roll on the top of the support ring 108. When the second ball bearings 111 roll along the inclined grooves 109 to the top of the support ring 108, the sliding columns 110 can drive the support plate 112 to move upward out of the groove 105, thereby pushing the pressed PP film, aluminum foil and inner circuit board out of the groove 105, so as to facilitate the removal of the pressed PP film, aluminum foil and inner circuit board.

[0029] The pressing mechanism 2 includes a support frame 201 fixedly connected to one side of the top of the base 101. A hydraulic rod 202 is fixedly fixed through the inside of the support frame 201, and the support frame 201 supports the hydraulic rod 202. A pressure plate 206 adapted to the groove 105 is detachably connected to the output end of the hydraulic rod 202. Activation of the hydraulic rod 202 drives the pressure plate 206 to move up and down, so that when the pressure plate 206 moves downward, it can squeeze the PP film, aluminum foil, and inner circuit board to be pressed. A positioning seat 205 is fixedly connected to the top of the pressure plate 206, and a matching positioning block 204 is inserted into the inside of the positioning seat 205.

[0030] Guide rods 203 are symmetrically fixedly connected to the top of the positioning block 204. Two sets of guide rods 203 slide through the support frame 201. The guide rods 203 guide the up-and-down movement of the positioning block 204 and the pressure plate 206. A pin 207 is slidably connected inside the positioning block 204 and the positioning seat 205. The pin 207 limits the positioning seat 205 and the positioning block 204, thus fixing the pressure plate 206 and facilitating subsequent disassembly and replacement of the pressure plate 206. A second spring 208 is fixedly connected between the pin 207 and the positioning seat 205. The second spring 208 pulls the pin 207 inwards towards the interior of the positioning block 204, reducing the risk of the pin 207 disengaging from the interior of the positioning block 204 and the positioning seat 205.

[0031] In use, the PP film, aluminum foil, and inner circuit board to be pressed are placed sequentially inside the groove 105 on one side and supported by the support plate 112. Then, the stepper motor 102 is started, causing the rotating seat 103 and the two sets of pressure seats 104 to rotate until one side pressure seat 104 is adjusted below the pressure plate 206. Then, the hydraulic rod 202 is started, causing the hydraulic rod 202 to move the pressure plate 206 downward, thereby pressing the PP film, aluminum foil, and inner circuit board inside the groove 105 on one side. During the pressing of PP film, aluminum foil, and inner circuit board, the worker can place the next set of PP film, aluminum foil, and inner circuit board to be pressed into another set of grooves 105. After the PP film, aluminum foil, and inner circuit board in one set of grooves 105 are pressed, the hydraulic rod 202 is activated again, causing the hydraulic rod 202 to drive the pressure plate 206 upward, causing the pressure plate 206 to disengage from the inside of the groove 105. Then, the stepper motor 102 is activated again, causing the stepper motor 10... 2. The rotating seat 103 and the pressure seat 104 are rotated, thereby adjusting the other pressure seat 104 to be below the pressure plate 206, so as to press the PP film, aluminum foil and inner circuit board to be pressed inside the groove 105 on the other side. As a set of pressure seats 104 rotates away from below the pressure plate 206, the second ball bearing 111 on the corresponding side rolls along the corresponding inclined groove 109 to the top of the support ring 108, thereby driving the corresponding sliding column 110 and the corresponding support plate 112 to move upward. This causes the support plate 112 to push the pressed PP film, aluminum foil and inner circuit board out of the groove 105, making it easier for workers to remove them. When another set of pressure seats 104 moves to the bottom of the pressure plate 206, the second ball bearing 111 corresponding to the pressure seat 104 rolls along the inclined groove 109 on the other side to the top of the support ring 108, causing the corresponding sliding column 110 and the corresponding support plate 112 to move downward, so that the corresponding support plate 112 moves back into the groove 105.

[0032] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
