Description

Technical Field

[0001] The utility model belongs to the technical field of laminators, in particular to a circuit board laminator. Background Art

[0002] A circuit board laminator is one of the key equipment used to manufacture printed circuit boards. Its main function is to bond multiple circuit layers together under high temperature and high pressure conditions to form a multi-layer PCB structure. In the prior art, a guide rail is installed on a base, a fixed pressure plate and a dynamic pressure plate are sleeved on the guide rail, and a lifter that can drive the dynamic pressure plate to move up and down is installed under the base to press the circuit board. However, in this method, the dynamic pressure plate and the fixed pressure plate are not easy to replace. When circuit boards of different sizes or shapes need to be produced, the fixed mold limits the production flexibility and cannot quickly adapt to product changes, affecting the needs of multi-variety and small batch production.

[0003] For example, the utility model with publication number CN206149607U discloses a new type of laminating machine. In the technical solution of this patent, a guide rail is usually provided at the upper end of the base, and both the fixed pressure plate and the movable pressure plate are sleeved on the guide rail. The fixed pressure plate and the guide rail are fixedly connected, and a lifter for the reciprocating movement of the movable pressure plate along the guide rail is provided at the bottom of the base to press and form the material. However, in this method, it is not convenient to replace the fixed pressure plate and the movable pressure plate. In the multi-variety production mode, the inconvenience of replacing the fixed pressure plate and the movable pressure plate will limit the rapid adaptation to the design and size requirements of different circuit boards, affecting production efficiency and market response speed. Utility Model Content

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0021] like Figure 1 , 2 As shown in Figure 3, the circuit board laminator includes a base frame 101, a fixing plate 102 is arranged at the upper end of the base frame 101, a telescopic push rod 103 is arranged at the upper end of the fixing plate 102, the output end of the telescopic push rod 103 extends into the lower end of the fixing plate 102 and is connected with a mounting plate 104, the lower end of the mounting plate 104 is detachably connected with a forming convex die 105, a plurality of support bars 106 are arranged at the bottom end of the base frame 101, a mounting plate 2 107 is arranged at the upper end of the support bars 106, the upper end of the mounting plate is detachably connected with a forming concave die 108, and fixing mechanisms are arranged on the mounting plate 104 and the mounting plate 2 107.

[0022] like Figure 1 , 2As shown, the fixing mechanism includes a fixing groove 201 opened in the mounting plate 104 and the mounting plate 2 107, and pins 202 are slidably arranged inside the two fixing grooves 201. One end of the two pins 202 is respectively connected to a cylinder 203, and each cylinder 203 is provided with a disc 204 at one end located outside the fixing groove 201. A spring 205 is sleeved on one end of the two cylinders 203 located inside the fixing groove 201, and one end of the spring 205 is connected to the pin 202, and the other side is connected to the inner side wall of the fixing groove 201. The forming convex mold 105 is provided with a slot 1 206 adapted to the pin 202, and the forming concave mold 108 is provided with a slot 2 207 adapted to the pin 202. By setting the fixing mechanism, when the forming convex mold 105 and the forming concave mold 108 need to be operated, During replacement, pulling the disc 204 can move the cylinder 203 to both ends, so that the pin 202 can slide out of slot one 206 and slot two 207 respectively, and then the forming punch 105 and the forming die 108 can be taken out. When the replacement is completed and the forming punch 105 and the forming die 108 need to be fixed, the disc 204 is released, and the pin 202 slides into the inside of slot one 206 or slot two 207 respectively under the action of the spring 205, so that the forming punch 105 or the forming die 108 is fixed on the mounting plate one 104 or the mounting plate two 107 respectively. The easy-to-replace mold design enables the production line to quickly adapt to different circuit board designs and production requirements without a large number of equipment adjustments, shortening the product conversion time and improving the versatility of the production line and the ability to respond to market changes.
