Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and specifically to a lamination device for metal-based circuit boards. Background Technology

[0002] Metal-based circuit boards, also known as metal substrates, are a special type of printed circuit board composed of a metal base, an insulating dielectric layer, and a conductive layer. Due to their excellent thermal conductivity, good machinability, electromagnetic shielding, and high voltage and bending resistance, they are widely used in high-power, high-frequency, and high-temperature environments, such as communication equipment, servers, automobile manufacturing, and high-frequency communication equipment.

[0003] Chinese patent discloses a multi-layer circuit board laminating device (publication number: CN219107848U). This device places the circuit boards to be laminated into a protective cover, stacking multiple circuit boards. After a small electric push rod is activated, it moves and adjusts the L-shaped clamping plates. When the four L-shaped clamping plates move relative to each other, they touch the four corners of the circuit boards, limiting the position of the stacked circuit boards inside the protective cover and preventing the circuit boards from shifting during subsequent lamination. However, this device still has the following drawbacks:

[0004] Although the clamping plate keeps the stacked circuit boards stable, it also obstructs the circuit boards from the surrounding area, making it inconvenient for operators to remove the pressed circuit boards. Furthermore, the circuit boards are prone to bumping and knocking when the operators handle them. Therefore, a pressing device for metal-based circuit boards is proposed to solve the above problems. Utility Model Content

[0029] The pressing mechanism 1 also includes a housing 101. The bottom of the inner wall of the housing 101 is fixedly installed with the electric cylinder 205. Guide cylinders 102 are embedded and fixedly installed on the upper end of the inner wall of the housing 101. Slide rods 103 are slidably connected to the inner walls of the two guide cylinders 102. One end of the slide rod 103 extends to the outside of the housing 101. A laser line projector 104 is fixedly installed on the inner wall of the slide rod 103 at that end. The laser line projector 104 is located above the lifting platform 201. Figure 2 As shown, the guide cylinder 102 limits the movement direction of the slide rod 103, thereby improving the stability of the slide rod 103 during movement;

[0030] A push plate 105 is fixedly installed at the end of the slide bar 103 away from the laser projector 104. A spring 106 is fixedly connected to the side of the push plate 105, and a fixing plate 107 is fixedly connected to the other side of the spring 106. The top of the fixing plate 107 is fixedly installed to the inner wall of the outer casing 101. Figure 2 As shown, the spring 106 pushes the push plate away from the fixed plate 107, thereby the slide bar 103 drives the laser projector 104 to the top of the lifting platform 201;

[0031] Pullers 108 are rotatably connected to both sides of the inner wall of the outer casing 101 and below the guide cylinder 102. Each pulley 108 has a movably contacting traction rope 109 on its outer wall. The top ends of the two traction ropes 109 are fixedly connected to push plates 105, and the bottom ends of the traction ropes 109 are fixedly connected to connecting plates 110. The tops of the two connecting plates 110 are fixedly installed to both sides of the clamp 204. Figure 2 As shown, the connecting plate 110 descends, and the traction rope 109 pulls the push plate 105 to move towards the fixed plate 107;

[0032] A support platform 111 is fixedly installed in the middle of the outer casing 101. A mounting frame 112 is fixedly installed on the top surface of the support platform 111. Both sides of the outer wall of the mounting frame 112 are fixedly installed with an electric cylinder 113. A sleeve 114 is fixedly installed on the surface of the mounting frame 112 near the electric cylinder 113. The extended end of the electric cylinder 113 passes through the inner side of the mounting frame 112 and is fixedly connected to a positioning plate 115. The other side of the positioning plate 115 extends out of the mounting frame 112 and is slidably connected to the inner wall of the sleeve 114. Figure 3 , Figure 5 As shown, the sleeve 114 limits the movement direction of the positioning plate 115, thereby improving the stability of the movement of the positioning plate 115.

The top front of the extension plate 116 is fixedly installed with the hydraulic cylinder 117. The extension end of the hydraulic cylinder 117 faces downward, and a pressure plate 118 is fixedly installed at the bottom of the extension end of the hydraulic cylinder 117. The pressure plate 118 is located directly above the support platform 111. The middle part of the surface of the support platform 111 is connected to the movable rod 202. The inner side of the mounting frame 112 surrounds the entire lifting platform 201.

[0034] The working principle of this utility model:

[0035] When the device is in use, the circuit board assemblies to be pressed are first placed layer by layer above the lifting platform 201. At this time, the laser beam output by the laser beam projector 104 assists the operator in simple positioning to avoid the circuit board assemblies on each layer being too tilted. Then, the extension end of the electric cylinder 205 drives the movable rod 202 to descend, and the lifting platform 201 drives the circuit board to fall into the inner side of the mounting frame 112 until the support foot 203 abuts against the surface of the support platform 111. During this period, the clamp 204 drives the connecting plate 110 to descend, thereby the traction rope 109 pulls the slide rod 103 to slide along the guide cylinder 102 and move towards the inside of the outer shell 101. The spring 106 is compressed by the force, and the laser beam projector 104 and the pressure plate 118 are completely misaligned.

[0036] Secondly, the two electric cylinders 113 simultaneously drive the positioning plate 115 to contact different sides of the circuit board, the circuit board is pushed and stacked neatly, the extension end of the hydraulic cylinder 117 extends, driving the pressure plate 118 to fall on the surface of the circuit board, thereby performing the pressing work. Finally, the hydraulic cylinder 117 drives the pressure plate 118 to rise, the electric cylinder 205 then drives the lifting platform 201 to rise and reset, the spring 106 releases elastic potential energy to extend, and pushes the slide bar 103, so that the laser projection device 104 moves above the lifting platform 201.

[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
