During their production and processing, multiple layers of sheets need to be pressed together through a pressing device.

[0003] Current lamination devices typically stack individual sheets sequentially within a limiting or positioning frame on a workbench, then use heat pressing to press the sheets together to form a single unit, thus producing a circuit board. However, due to the constraints and obstructions of the limiting or positioning frame, lamination can only be performed on sheets of a specific size, making it difficult to adjust to actual production needs. Therefore, a non-deviating lamination device for circuit board production is proposed. Summary of the Invention

Through the cooperation of the positioning mechanism and the pressing mechanism, the pressing of circuit board sheets of various sizes can be achieved, which can better meet actual usage needs.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-deviation pressing device for circuit board production, comprising a cabinet and a working chamber, wherein a positioning mechanism is slidably mounted on the bottom of the working chamber to prevent the stacked sheets from deviating, a pulling mechanism is disposed between the working chamber and the positioning mechanism to push the positioning mechanism out of the working chamber or pull it back into the working chamber, and a pressing mechanism is mounted on the top of the working chamber at a position corresponding to the positioning mechanism; The pressing mechanism includes a box with an open bottom and two hydraulic rods installed on the top of the studio to drive the box to move.

DETAILED DESCRIPTION

[0018] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Example 1 After the current circuit board pressing device is equipped with a positioning device, it is usually only able to press circuit boards of a specific size due to the obstruction of the positioning device, which limits its application. This embodiment provides an anti-deviation pressing device for circuit board production, such as Figures 1-10 As shown, the cabinet 1 and the workroom 2 are provided with a positioning mechanism 3 slidably mounted on the bottom of the workroom 2 to prevent the stacked sheets from shifting. A pulling mechanism 4 is provided between the workroom 2 and the positioning mechanism 3 to push the positioning mechanism 3 out of the workroom 2 or pull it back into the workroom 2. Furthermore, a pressing mechanism 5 is installed at the top of the workroom 2 at a position corresponding to the positioning mechanism 3. The positioning mechanism 3 is moved out of the workroom 2 by the pulling mechanism 4. At this time, the staff can conveniently stack the sheets on the positioning mechanism 3 in sequence. After the stacking is completed, the pulling mechanism 4 is controlled to move the positioning mechanism 3 back into the workroom 2, and then the pressing mechanism 5 is controlled to press the sheets on the positioning mechanism 3.

[0020] As for the positioning mechanism 3: The positioning mechanism 3 includes a movable seat 38 slidably mounted on the bottom of the workroom 2. A shell base 31 with a cross-shaped opening is fixed to the top of the movable seat 38. A matching heating plate 6 is installed on the top of the shell base 31. The heating plate 6 can be used to heat the stacked sheets for pressing. A cross rod 33 is rotatably mounted in the shell base 31. A connecting rod 34 is rotatably mounted on the end of the cross rod 33. A push-pull rod 35 is rotatably mounted on the other end of the connecting rod 34. A limit rod 36 fixed to the shell base 31 is slidably mounted on the other end of the push-pull rod 35. An anti-deflection portion 37 is provided on the top of the push-pull rod 35. A servo motor 32 is installed in the movable seat 38 to drive the cross rod 33 to rotate. When the servo motor 32 is started, the cross rod 33 is driven to rotate. Through the transmission of the connecting rod 34 and the constraint of the limit rod 36, the four groups of push-pull rods 35 can be driven to move outward or inward at the same time, thereby driving the four groups of anti-deflection portions 37 to move inward or outward. The minimum size of the circuit board sheet is determined by the minimum area surrounded by the four groups of anti-deviation parts 37 , and the maximum size of the circuit board sheet is determined by the maximum area surrounded by the four groups of anti-deviation parts 37 .

[0021] For the positioning of the smallest sized circuit board: the four groups of anti-deflection parts 37 are controlled to move inward to the innermost side, so that the area enclosed by the four groups of anti-deflection parts 37 is the smallest. The sheets of the smallest size are stacked on the heating plate 6, and the four groups of anti-deflection parts 37 position them to prevent the stacked sheets from shifting. For the positioning of the smallest sized circuit board: the four groups of anti-deflection parts 37 are controlled to move outward to the outermost side, so that the area enclosed by the four groups of anti-deflection parts 37 is the largest. The sheets of the largest size are stacked on the heating plate 6, and the four groups of anti-deflection parts 37 position them to prevent the stacked sheets from shifting. The anti-deflection portion 37 comprises a chute 371 fixed to the top of the push-pull rod 35. A slide 374 is slidably mounted within the chute 371. A slide rod 372, fixed to the chute 371, is slidably mounted on the slide 374. A spring 1 373 is sleeved around the slide rod 372. An anti-deflection rod 375, extending from an opening, is fixed to the top of the slide 374. Under the elastic force of the spring 1 373, the slide 374 and its anti-deflection rod 375 are squeezed inward. When the sheets are stacked on the heating plate 6, any sheet not positioned in the center is squeezed and adjusted by the four sets of anti-deflection rods 375, ensuring that it is in the center.

[0022] As for the pressing mechanism 5: The above-mentioned pressing mechanism 5 includes a box body 54 with an open bottom, and a hydraulic rod 53 installed on the top of the studio 2 to drive the box body 54 to move. By starting the hydraulic rod 53, the box body 54 can be driven to move up or down. A pressing part 52 is provided in the box body 54, which can change the pressing size according to the size of the circuit board, and a power part 51 is provided on the upper part of the box body 54 to cooperate with the pressing part 52.

[0023] The pressing part 52 mentioned above includes several groups of inwardly contracted and mutually slidably mounted return plates 522. The outermost return plate 522 is fixed to the inner wall of the box body 54. The inner end of the innermost return plate 522 is slidably mounted with a center plate 521. The inner end of the return plate 522 is symmetrically provided with a slideway 523, and multiple groups of elastic members 524 are installed in the slideway 523. Figure 10 The protruding portion of the edge of the middle plate 521 is slidably installed in the slide 523 at the inner end of the innermost return plate 522. Similarly, the protruding portion of the edge of the innermost return plate 522 is slidably installed in the slide 523 at the inner end of the adjacent return plate 522, and so on. The same is true for the remaining return plates 522.

[0024] The pressing section 52 mentioned above includes a bidirectional screw 511 rotatably mounted within a housing 54. A moving block 514 is symmetrically threaded onto the bidirectional screw 511. A guide rod 512 is slidably mounted on the moving block 514, fixed to the inner wall of the housing 54. Two guide rods 512 are provided, one on either side of the bidirectional screw 511. A hydraulic rod 1 515 is mounted at the bottom end of the moving block 514. A servo motor 3 513 is mounted on the outer end of the housing 54 to rotate the bidirectional screw 511. Activating the servo motor 3 513 drives the bidirectional screw 511 to rotate, and under the constraints of the guide rod 512, it can drive the two sets of moving blocks 514 to move inward or outward simultaneously.

[0025] The above-mentioned pressing part 52 and the pressing part 52 work in coordination, and only through the close coordination between the two can the change of the pressing size be achieved.

[0026] For example, when laminating the smallest size circuit board: after stacking the smallest size sheets and moving them back into the studio 2, the moving blocks 514 on both sides are controlled to move inward at the same time until the two sets of moving blocks 514 are located directly above the center plate 521. At this time, the hydraulic rod 1 515 is activated, and the movable end of the hydraulic rod 1 515 is extended to push the center plate 512 downward for a greater distance (at this time, the elastic member 524 is compressed), and the innermost return rod 522 is affected by the innermost return rod 522 adjacent to it. The elastic force of the elastic member 524 causes the innermost return rod 522 to deflect downward only slightly, without affecting the downward projection of the center plate 512, so as to meet the minimum circuit board size limited by the four sets of anti-deflection rods 375. Then, the hydraulic rod 53 is activated to drive the box body 54 and the center plate 512 thereon to move downward until the center plate 512 is completely pressed against the sheet. At this time, since the innermost return plate 522 moves downward a very small distance, it will not come into contact with or squeeze the anti-deflection rods 375. For the lamination of the largest sized circuit board: the return plate 522 adjacent to the outermost return plate 522 is denoted as return plate A. After the sheets of the largest size are stacked and moved back into the working room 2, the hydraulic rods 515 on both sides are controlled to be located directly above the return plate A. The hydraulic rods 515 are activated, and the movable ends of the hydraulic rods 515 extend, pushing the return plate A downward, and at the same time driving the remaining return plates 522 and the center plate 521 downward together, so as to press the stacked sheets of the largest size. It can be seen that with the cooperation of the pressing part 52 and the power part 51, it is possible to press circuit board sheets of various sizes, which can better meet actual usage needs.

[0027] The elastic member 524 comprises a vertical rod 5241 slidably connected to the center plate 521 or the return plate 522. A second spring 5242 is sleeved on the vertical rod 5241. The elastic force of the second spring 5242 supports the center plate 521 or the return plate 522 upward. When the first hydraulic rod 515 moves upward and away from the center plate 521 or the return plate 522, the center plate 521 or the return plate 522 moves upward to its original position.

[0028] Example 2 On the basis of Example 1, Figure 1-Figure 3 As shown, from Figure 1 As can be seen, the pressing mechanism 5 is located directly above the positioning mechanism 3. It is inconvenient for the staff to place the sheet due to the obstruction of the pressing mechanism 5. Therefore, the pulling mechanism 4 is provided, which includes racks 41 symmetrically fixed to the outer ends of the moving base 38, and gears 42 meshing with the two sets of racks 41. A servo motor 2 43 is installed in the working room 2 to drive the gears 42 to rotate. The output shaft of the servo motor 2 43 is fixed to the center of the gear 42. Figure 1As a benchmark, the up and down, left and right, and front and back directions are determined. When the sheet needs to be placed, the servo motor 2 43 is started to drive the gear 42 to rotate, which can drive the rack 41 to move forward, thereby driving the positioning mechanism 3 to move forward. At this time, the top of the positioning mechanism 3 is no longer blocked by the pressing mechanism 5, and the staff can more conveniently stack the sheets on the positioning mechanism 3.
