[0002] During the production process of multi-layer circuit boards, in order to ensure the pressing quality of the circuit boards and the flatness of the circuit board surfaces, steel plates are often placed between two adjacent circuit boards. When the circuit boards are processed and transferred to the next process, the steel plates and circuit boards need to be placed separately.

One is arranged on one side of the length direction of the positioning plate 41, and the other is arranged on the other side of the length direction of the positioning plate 41. A first bidirectional lead screw 43 is rotatably connected to the adsorption plate 23. The first bidirectional lead screw 43 penetrates through the two moving plates 42 and the positioning plate 41. One end of the first bidirectional lead screw 43 is threadedly connected to one moving plate 42, and the other end is threadedly connected to the other moving plate 42. By rotating the first bidirectional lead screw 43, the two moving plates 42 can be driven to approach or separate from each other. Three moving grooves 44 are formed on each moving plate 42. The moving grooves 44 are arranged at intervals along the length direction of the moving plate 42 and penetrate the moving plate 42 along the thickness direction of the moving plate 42.

[0041] Referring to Figure 4 , the adjusting assembly 4 further includes a fixing plate 47 and an adjusting plate 48. The fixing plate 47 is fixed in the middle of the adsorption groove 40. The fixing plate 47 is perpendicular to the positioning plate 41 and is arranged at the bottom of the positioning plate 41. There are two adjusting plates 48. One of them is slidably installed on one side in the length direction of the fixing plate 47, and the other is slidably installed on the other side in the length direction of the fixing plate 47. A second bidirectional lead screw 49 is rotatably connected in the adsorption groove 40. The second bidirectional lead screw 49 passes through the fixing plate 47 and the two adjusting plates 48.

The second helical gear 68 meshes with the first helical gear 64. When the first double - lead screw 43 is rotated, the first double - lead screw 43 drives the first synchronous pulley 61 to rotate. The first synchronous pulley 61 drives the second synchronous pulley 62 to rotate through the first synchronous belt 63. The second synchronous pulley 62 drives the first helical gear 64 to rotate. The first helical gear 64 drives the second helical gear 68 to rotate. The second helical gear 68 drives the fourth synchronous pulley 66 to rotate through the third synchronous pulley 65, thereby driving the second double - lead screw 49 to rotate. Thus, while adjusting the distance between the two moving plates 42, the distance between the two adjusting plates 48 can be adjusted, which helps to improve the adjustment efficiency.

[0043] Refer to Figure 6 , connecting plates 7 are fixed at the four corners of the adsorption plate 23.

[0044] Refer to Figure 7 , an installation groove 74 is formed in the adsorption plate 23, and a driving assembly 8 for driving the second adsorption assembly 25 to move is arranged in the installation groove 74. The driving assembly 8 includes a driving rack 81, a rotating gear 82, a driven gear 83 and a driven rack 84. One end of the driving rack 81 is fixed on the moving plate 42 or the adjusting plate 48, so as to Figure 7Taking a set of drive components 8 in the lower left corner as an example, the drive rack 81 is fixed on the adjusting plate 48, and the moving direction of the drive rack 81 is the same as that of the adjusting plate 48. The rotating gear 82 is rotatably connected in the mounting groove 74, the rotating gear 82 meshes with the drive rack 81, the driven gear 83 is rotatably connected in the mounting groove 74, the driven gear 83 meshes with the rotating gear 82, the driven rack 84 is fixed on the second adsorption component 25, and the driven rack 84 meshes with the driven gear 83. When the second bidirectional lead screw 49 drives the two adjusting plates 48 to approach or move away from each other, the adjusting plate 48 can drive the drive rack 81 to move, the drive rack 81 drives the rotating gear 82 and the driven gear 83 to rotate, and then drives the driven rack 84 and the second adsorption component 25 to move. By setting the drive component 8, the distance between the second adsorption components 25 can be adjusted while adjusting the distance between the first adsorption components 24, so as to adsorb steel plates of different sizes and improve the applicability of the equipment.

[0045] The implementation principle of the embodiment of this application is as follows: According to the size of the steel plate, the positions of the first adsorption component 24 and the second adsorption component 25 are adjusted. By rotating the first bidirectional lead screw 43, the first bidirectional lead screw 43 drives the two moving plates 42 to approach or move away from each other. At the same time, the first bidirectional lead screw 43 drives the second bidirectional lead screw 49 to rotate through the linkage component 6, and the second bidirectional lead screw 49 drives the two adjusting plates 48 to approach or move away from each other. When the adjusting plate 48 and the moving plate 42 are moving, they can drive the drive rack 81 to move. Under the driving action of the rotating gear 82 and the driven gear 83, the drive rack 81 drives the driven rack 84 to move, and the driven rack 84 drives the second adsorption component 25 to move, realizing the adjustment of the position of the second adsorption component 25. Thus, the positions of the first adsorption component 24 and the second adsorption component 25 are adjusted according to the size of the steel plate, while ensuring the adsorption effect on the steel plate, the applicability of the equipment is enhanced.
