When in use, under the driving of the top rod 3312, the multiple groups of clamping assemblies will clamp the workpiece when moving under force, so as to realize the fixing.

[0047] Further, the clamping assembly comprises a product limiting block 3331, a sliding block 3332, a pressing rod 3333, a spring 3334 and a spring fixing block 3335. The product limiting block 3331 is fixedly arranged on the second fixing block 320.

Since the track groove 3336 is connected with the sliding of the pressing rod 3333, when the sliding block 3332 slides, the pressing rod 3333 is driven by the track groove 3336 to slide along the product limiting block 3331, that is, the pressing rod 3333 drives the spring fixing block 3335 to displace relative to the workpiece on the second fixing block 320, so as to realize the clamping or unclamping of the workpiece.

[0048] It should be noted that, in order to realize the synchronous drive of the multiple clamping assemblies, the sliding blocks 3332 of the adjacent two clamping assemblies are connected with connecting rods 3338 through pin shafts. Specifically, the end of the sliding block 3332 close to the top rod 3312 is used to contact with the top rod 3312, and no connecting rod 3338 is arranged thereon. The sliding block 3332 close to the fixing seat 3321 is used to telescopically connect with the fixing seat 3321, that is, the sliding block 3332 and the fixing seat 3321 are connected with the telescopic spring 3322.

[0050] Further, in order to realize the movement of the second fixed block 320 relative to the base 310, the transplanting station further comprises a linear motion assembly for driving the second fixed block 320 to move, which can be a linear motor or a structure of motor and screw, of course, other structures capable of realizing the movement of the second fixed block 320 relative to the base 310 can also achieve the technical effects of the present application.

[0051] As a preferred technical solution of the present application, the transplanting station 30 further comprises a compression mechanism 350, the number of the compression mechanism 350 is multiple, and is distributed along the length direction of the base 310, preferably, the compression mechanism 350 is arranged at equal intervals along the length direction of the base 310, specifically, the compression mechanism comprises a column 351, a cross beam 352, a vertical cylinder 353 and a compression roller 354, the cross beam 352 extends outward from the top of the column 351 to the upper side of the base 310, the vertical cylinder 353 is fixedly arranged on the cross beam, and the vertical cylinder 353 is arranged along the vertical direction, the compression roller 354 is arranged at the output end of the cylinder, in use, under the drive of the vertical cylinder 353, the compression roller 354 can move vertically, so that the compression roller 354 can be moved to contact the water-cooled plate, so that when the film is pasted on the water-cooled plate by the film pasting mechanism, the film layer is effectively pasted on the surface of the water-cooled plate by the contact between the compression roller 354 and the film layer.

[0052] Referring to Figure 5As a preferred technical scheme of the present application, the film pasting mechanism 50 comprises a rack 510, a vertical plate 520, a preheating plate 530, a motor 540, a lead screw 550, a driven wheel 560, a film discharge roller 570, a film guide plate 580 and a film stripping block 590.

The film stripping block 590 is arranged on the vertical plate 520 and is inclined from the film guide plate 580 to the driven wheel 560. When in use, the preheated water-cooled plate is clamped by the transfer station and is transferred to the film pasting station. At this time, the film discharge roller 570 above starts to send the film. The film layer is output outward after passing through the film guide plate 580 and the film stripping block 590. Since the film used in the present application is divided into two layers, one is black film and the other is white film. When in use, the black film and the white film are separated by the film stripping block. The black film is pasted on the water-cooled plate. The white film is wound by the film collecting roller after being peeled off. Specifically, the black film is sent to the surface of the product at an angle of about 30° with the water-cooled plate.
