[0002] Chinese Patent No. CN214070256U discloses a pressing device for PCB board production, including a base, a fixed pressure plate disposed at the center of the top surface of the base, and a left vertical plate and a right vertical plate disposed on the left and right sides of the top surface of the base, respectively, including a pressing mechanism; the left and right vertical plates are respectively provided with a first strip-shaped through hole and a second strip-shaped through hole vertically in the middle part; the pressing mechanism includes a left pressing mechanism and a right pressing mechanism of the same size, which are respectively disposed on the right side of the left vertical plate and the left side of the right vertical plate, and are in a left-right symmetrical state; the left pressing mechanism includes a bearing plate and a movable plate. In order to solve the problem of uneven pressure applied to the copper-clad laminate by the pressure plate on the pressing device, a pressing device for PCB board production is provided to ensure that the pressure of the pressure plate on the copper-clad laminate is uniform.

[0003] This device can be used for PCB production to ensure uniform pressure on the copper-clad laminate by the pressure plate on the laminating device. However, the device does not have a copper-clad laminate fixing structure, which can easily cause the copper-clad laminate to shift during the lamination process. Therefore, an improvement was proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that lack a copper-clad laminate fixing structure, which can easily lead to copper-clad laminate displacement during the lamination process. Therefore, this invention proposes a lamination device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a pressing device, including a frame, an internal worktable, a hydraulic device fixedly mounted on the upper surface of the frame, an output end of the hydraulic device fixedly connected to a movable pressure plate that cooperates with the worktable, four sets of symmetrical moving slots symmetrically arranged in the front, back, left and right of the worktable, clamping plates slidably connected inside the moving slots, and an installation chamber inside the frame, with a drive assembly for moving the clamping plates inside the installation chamber.

[0007] The drive assembly includes a lifting plate, on which dual-head motors are fixedly installed on both the upper and lower end faces. The two sets of dual-head motors are arranged perpendicularly and staggered. The output shafts at both ends of the dual-head motors are connected to lead screws. The four sets of lead screws pass through the four sets of clamping plates respectively.

[0008] Preferably, the lifting plate has a sliding groove inside that cooperates with the clamping plate, and a driving block is slidably connected inside the sliding groove. The driving block is fixedly connected to the corresponding clamping plate.

[0009] Preferably, two sets of mounting plates are fixedly connected to the upper and lower end faces of the lifting plate, and the dual-head motor is fixedly installed between the two sets of mounting plates.

[0010] Preferably, two sets of fixing blocks are fixedly connected to the upper and lower end faces of the lifting plate, and the other end of the lead screw is inserted into and rotates inside the fixing blocks.

[0011] Preferably, the installation chamber has multiple sets of guide rods fixedly connected inside, and the lifting plate is slidably sleeved on the outer end face of the guide rods.

[0012] Preferably, an elastic element is sleeved on the outer end face of the bottom of the guide rod, and the upper end of the elastic element abuts against the lifting plate and moves upward.

[0013] Preferably, positioning grooves are provided on both the left and right sides of the frame, and positioning strips are fixedly connected to both the left and right end faces of the movable pressure plate, with the positioning strips slidably connected inside the positioning grooves.

[0014] The pressing device proposed in this utility model has the following advantages: By driving the lead screw to rotate via a dual-head motor, and with the cooperation of the sliding groove and the drive block, the clamping plates can be moved, causing two symmetrical sets of clamping plates to move inward simultaneously. Under the joint drive of the two sets of dual-head motors, all four sets of clamping plates move towards the center simultaneously. This allows the copper-clad laminate to be clamped and fixed towards the center when placed on the worktable, preventing the copper-clad laminate from shifting during the pressing process of the movable pressure plate. When the movable pressure plate presses down, it abuts against the clamping plates, causing the lifting plate to move downward. At this time, the elastic element can be compressed, preventing the clamping plates from affecting the pressing of the copper-clad laminate. After pressing, the elastic element can abut against the lifting plate to reset. This device can fix copper-clad laminates of different sizes, preventing them from shifting during the pressing process, improving the pressing quality of the device, and has excellent practicality.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A pressing device includes a frame 1, a worktable 2 inside the frame 1, a hydraulic device 4 fixedly installed on the upper end of the frame 1, a movable pressure plate 401 that cooperates with the worktable 2 fixedly connected to the output end of the hydraulic device 4, four sets of moving slots 201 symmetrically arranged in the front, back and left and right sides inside the worktable 2, a clamping plate 3 slidably connected inside the moving slots 201, and an installation chamber 101 inside the frame 1, and a drive assembly for driving the clamping plate 3 to move inside the installation chamber 101.

[0023] The drive assembly includes a lifting plate 5. Two dual-head motors 6 are fixedly installed on the upper and lower end faces of the lifting plate 5. The two sets of dual-head motors 6 are arranged vertically and staggered. The output shafts at both ends of the dual-head motors 6 are connected to lead screws 601. The four sets of lead screws 601 pass through and drive four sets of clamping plates 3 respectively. The four sets of clamping plates 3 move towards the center at the same time. In this way, when the copper-clad laminate is placed on the worktable 2, it can be clamped and fixed towards the center to prevent the copper-clad laminate from shifting during the pressing process of the movable pressure plate 401. At the same time, the lifting plate 5 can move downward, which can avoid the clamping plates 3 from affecting the pressing of the copper-clad laminate.

[0024] The lifting plate 5 has a sliding groove 501 inside that cooperates with the clamping plate 3. A driving block 301 is slidably connected inside the sliding groove 501. The driving block 301 is fixedly connected to the corresponding clamping plate 3. The movement of the clamping plate 3 can be restricted by the cooperation of the sliding groove 501 and the driving block 301.

[0025] Two sets of mounting plates 503 are fixedly connected to the upper and lower end faces of the lifting plate 5. The dual-head motor 6 is fixedly installed between the two sets of mounting plates 503. The mounting plates 503 facilitate the installation of the dual-head motor 6.

[0026] Two sets of fixing blocks 502 are fixedly connected to the upper and lower end faces of the lifting plate 5. The other end of the screw 601 is inserted into and rotates inside the fixing block 502. The fixing block 502 can support the rotation of the screw 601.

[0027] Multiple sets of guide rods 103 are fixedly connected inside the installation chamber 101. The lifting plate 5 is slidably sleeved on the outer end face of the guide rods 103. The movement of the lifting plate 5 can be restricted by setting the guide rods 103.

[0028] An elastic element 7 is fitted on the outer end face of the bottom of the guide rod 103. The upper end of the elastic element 7 abuts against the lifting plate 5 and moves upward. The lifting plate 5 can be reset by setting the elastic element 7.

[0029] Positioning grooves 102 are provided on both the left and right sides of the frame 1. Positioning strips 402 are fixedly connected to the left and right end faces of the movable pressure plate 401. The positioning strips 402 are slidably connected inside the positioning grooves 102. Through the cooperation of the positioning strips 402 and the positioning grooves 102, the movable pressure plate 401 is prevented from shifting during movement.

[0030] Working method: During operation, the copper-clad laminate is placed on the worktable 2. Two sets of dual-head motors 6 drive the lead screw 601 to rotate, which in turn moves the clamping plates 3. All four sets of clamping plates 3 move towards the center simultaneously, which can clamp and fix the copper-clad laminate towards the center, preventing the copper-clad laminate from shifting during the pressing process of the movable pressure plate 401. Then, the hydraulic device 4 drives the movable pressure plate 401 to move downward to perform the pressing work. When the movable pressure plate 401 presses down, it will abut against the clamping plates 3, thereby causing the lifting plate 5 to move downward. At this time, the elastic element 7 can be compressed by force, avoiding the clamping plates 3 from affecting the pressing of the copper-clad laminate. After the pressing is completed, the elastic element 7 can abut against the lifting plate 5 to reset. This device can fix copper-clad laminates of different sizes and prevent them from shifting during the pressing process, which improves the pressing quality of the device and has good practicality.
