The driving component 121 drives the transmission rod 122 to rotate. The transmission rod 122 drives the turntable 123 to rotate. The turntable 123 rotates relative to the base. The base is installed on the first lower plate 114. The turntable 123 connects the first moving component 125 and the second moving component 126 through a plurality of connecting rods 124. Exemplarily, there are four connecting rods 124, namely the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod. Specifically, the turntable 123 connects the first moving component 125 through two connecting rods 124 (such as the first connecting rod and the second connecting rod) respectively, so that the two first moving components 125 approach or move away from each other. For example, the two first moving components 125 approach or move away from the first lower plate 114, so that a plurality of jaws 127 clamp or release the workpiece in the width direction. The turntable 123 connects the second moving component 126 through the other two connecting rods 124 (such as the third connecting rod and the fourth connecting rod) respectively, so that the two second moving components 126 approach or move away from each other, and the two second moving components 126 approach or move away from the first lower plate 114, so that a plurality of jaws 127 clamp or release the workpiece in the length direction. The first moving component 125 is slidably connected to the first lower plate 114, and the second moving component 126 is slidably connected to the first lower plate 114. The sliding connection method can be, for example, a conventional slide rail and slider, a chute and slider, etc. Therefore, under the action of the driving component 120, the two first moving components 125 approach or move away from each other, and the two second moving components 126 approach or move away from each other, so that a plurality of jaws 127 clamp or release the workpiece in the circumferential direction.

[0054] The first lifting abutting part includes a lifting part 130 and an abutting part 140.

[0055] The abutting part 140 includes an abutting component 141 and a mounting component 142. A plurality of abutting parts 140 are provided on the lower plate 134. The plurality of abutting parts 140 form a matrix to abut the workpiece, so as to position the workpiece well. The mounting component 142 is installed on the lower plate 134.

The lifting column 133 and the first lifting pipe 113 are sleeved, so that relative guiding movement in the lifting direction can be realized between the lifting column 133 and the first lifting pipe 1123.

[0056] When the first driving part 111 drives the first moving part to move, the first moving part drives the first lifting plate 112 to move up and down. Since the first lifting tube 133 is connected between the first lifting plate 132 and the first lower plate 134, it further drives the first lifting contact part and the clamping part to move up and down to approach or move away from the workpiece. When approaching the workpiece, the clamping part 120 can clamp or release the clamping of the workpiece. Specifically, the driving component 121 drives the transmission rod 122 to rotate, the transmission rod 122 drives the turntable 123 to rotate, the turntable 123 drives a plurality of connecting rods to rotate, causing the first moving component 125 and the second moving component 126 to move relative to the first lower plate 114, so that the first moving component 125 and the second moving component 126 approach or move away from the lower plate, and further enabling the jaws of the first moving component 125 and the jaws of the second moving component 126 to clamp or release the clamping of the workpiece.

[0057] When the driving part 131 drives the moving part to move, the moving part drives the lifting plate 132 to move up and down. Since the lifting column 133 is connected between the lifting plate 132 and the lower plate 134, it further drives the lower plate 134 to move up and down. The lower plate 134 drives the contact part 140 to move up and down, and the contact component 141 of the contact part 140 will contact or disengage from the workpiece.

Exemplarily, both sides of the adjusting component 211 are movably mounted on multiple mounting components 212, or the adjusting component 211 can also be slidably mounted on the mounting components 212 through sliders. The transmission components 214 and driving components 215 are mounted on the bearing plate 221. The driving component 215 drives the transmission component 214 to rotate, and the rotation of the transmission component 214 drives the adjusting component 211 to move, for example, by using a conventional lead screw and nut pair. A supporting component 213 is provided on the adjusting component 211, and the supporting component 213 can support the workpiece in a point support mode, a line support mode or a surface support mode. The upper unit places the workpiece on the lower unit 200. Specifically, the first lifting and clamping part places the workpiece on the bearing part 220 and the adjusting part 210. The role of the adjusting part 210 is crucial and necessary because if the adjusting part 210 is not provided, the flexibility of the workpiece will cause the workpiece to sink and deform. The role of the adjusting part can provide multiple positions to support the workpiece, can reduce or avoid the deformation of the workpiece, and avoid affecting the position and accuracy of subsequent laser etching processing.

[0060] The adjusting part 230 includes a lower mounting part 231, an upper mounting part 233, and a UVW unit 232.

The driving part 241 drives the moving part 242 to move, and the movement of the moving part 242 drives the lifting part 244 to move up and down. The lifting part 244 drives the bearing part 220 and / or the adjusting part 210 to move up and down.

[0061] The upper unit 100 further includes an image detection unit 150, and a plurality of image detection units 150 are provided on the cover plate G, for accurately placing the workpiece on the carrying unit 220. Specifically, the plurality of image detection units 150 are used to obtain the posture or mark of the carrying unit 220, and the adjustment unit 230 adjusts the posture of the carrying unit 220 so that the first lifting and clamping unit accurately places the workpiece on the carrying unit 220 and the adjustment unit 210. Specifically, four image detection units 150 can be set, and the four image detection units 150 are set at the four corners of the cover S. After the upper unit 100 receives the workpiece, the subsequent workpiece needs to be placed on the lower unit 200. When the first lifting unit 110 drives the workpiece to descend to the first height of the bearing part of the lower unit 200, the two diagonal image detection units 150 obtain the postures or marks of the two diagonals of the bearing part 220, and the adjustment unit 230 compensates and adjusts the posture of the bearing part 220. The workpiece is placed on the bearing part 220 and the adjustment part 210. At this time, the other two diagonal image detection units 150 obtain the postures or marks of the other two diagonals of the bearing part to determine whether the workpiece is accurately placed on the bearing part 220. When the result is no, the first lifting part 110 drives the workpiece to rise. When the workpiece rises to the second height of the carrying part of the lower unit 200, the adjustment part 230 compensates and adjusts the posture of the carrying part 220 based on the results of the posture or mark of the other two diagonals of the carrying part obtained by the two image detection parts 150 at the other diagonals, so as to accurately place the workpiece on the carrying part 220 and the adjustment part 210.
