The movable clamping block 539, the fixed clamping block 534 and the support base 533 jointly define a clamping space 530 for placing the workpiece 200. The clamping driving member 537 can drive the movable clamping block 539 to move close to or away from the fixed clamping block 534, so as to clamp or release the workpiece 200 in the clamping space 530. When the first translation member 51 and the second translation member 52 move, the workpiece 200 in the clamping space 530 can be translated to the position corresponding to the pad 30, so that the pad 30 can perform the pad printing operation.

[0031] In the embodiment, the rotating driving member 531 is a motor. The rotating driving member 531 comprises a motor body 538 and a motor shaft (not shown in the figure) rotatably arranged on the motor body 538. The motor body 538 of the rotating driving member 531 is fixed to one side of the vertical plate 523. The motor shaft of the rotating driving member 531 rotatably penetrates the vertical plate 523. Specifically, a rotating hole (not shown in the figure) is formed through the vertical plate 523. The motor shaft rotatably penetrates the rotating hole. The motor shaft is parallel to the second horizontal direction Y. In the embodiment, the support base 533 is substantially in the shape of a flat plate. The support base 533 is located on the side of the vertical plate 523 away from the motor body 538. The support base 533 is connected to the motor shaft, so as to rotate under the driving of the rotating driving member 531.

[0032] The fixed clamping block 534, the movable clamping block 539 and the clamping driving member 537 are arranged on the top surface of the support base 533. The fixed clamping block 534 comprises an end plate 535 and a side blocking portion 536, both of which are fixedly connected to the top surface of the support base 533, and the side blocking portion 536 is vertically connected to one end of the end plate 535 away from the movable clamping block 539; the movable clamping block 539 is slidingly arranged between the clamping driving member 537 and the end plate 535; the movable clamping block 539 can abut against one end of the end plate 535 away from the side blocking portion 536, so as to clamp the workpiece 200. The clamping driving member 537 can be a cylinder or the like in the prior art.

[0033] Please refer to Figure 6 In the initial state, the clamping assembly 50 is located away from the pad printing rubber head 30, and the movable clamping block 539 is located away from the fixed clamping block 534, so as to facilitate the worker to place the workpiece 200. When the pad printing machine 100 is used, first, the worker places the workpiece 200 in the clamping space 530 formed by the movable clamping block 539 and the fixed clamping block 534, and places the side surface 211 to be pad printed upward, and makes the plug 230 of the body 210 contact the inner side surface of the end plate 535 of the fixed clamping block 534. At this time, the end surface 213 of the body 210 away from the plug 230 is flush with the side surface of the support base 533 away from the plug 230, or the end surface 213 of the body 210 away from the plug 230 protrudes out of the side of the support base 533 away from the plug 230. Then, the movable clamping block 539 is driven by the clamping driving member 537 to move towards the fixed clamping block 534 until the movable clamping block 539 abuts against one end of the end plate 535 away from the side blocking portion 536. At this time, the movable clamping block 539 and the fixed clamping block 534 clamp the opposite side surfaces of the body 210 of the workpiece 200 respectively, so as to clamp and fix the workpiece 200. It can be understood that the contact surface of the movable clamping block 539 for contacting the workpiece 200 and the contact surface of the fixed clamping block 534 for contacting the workpiece 200 are matched with the surface shape of the workpiece 200. For example, when the surface of the workpiece 200 contacting the movable clamping block 539 or the fixed clamping block 534 is a curved surface, the contact surface of the movable clamping block 539 and the contact surface of the fixed clamping block 534 are arc surfaces matched with the surface shape of the corresponding workpiece, so as to increase the contact area of the workpiece 200 with the movable clamping block 539 and the fixed clamping block 534, and further make the clamping more stable.

[0034] After the workpiece 200 is clamped and fixed, the workpiece is moved to one of the pad printing rubber heads 30 through the movement of the first and second translation members 51 and 52, and the side surface 211 of the body 210 is pad printed by the corresponding pad printing rubber head 30. After the side surface 211 is pad printed, the rotating drive member 531 drives the support seat 533 to rotate 90°, so that the end surface 213 of the body 210 away from the plug 230 faces upward, and then the workpiece 200 is moved to the position of another pad printing rubber head 30 through the movement of the first and second translation members 51 and 52, and the end surface 213 of the body 210 is pad printed by the other pad printing rubber head 30.

[0035] When the pad printing machine 100 is used, the workpiece 200 is placed in the clamping space 530 on the support seat 533, and the workpiece 200 can be moved to the pad printing rubber head 30 for pad printing by the movement of the first and second translation members 51 and 52; the support seat 533 and the workpiece 200 placed in the clamping space 530 can be rotated by the rotating drive member 531, so that different surfaces of the workpiece 200 are opposite to the pad printing rubber head 30, and then the two different surfaces of the workpiece 200 can be pad printed by the pad printing machine 100, the production cost is reduced, and the work efficiency is improved without the need of clamping the workpiece twice.

[0036] The pad printing machine 100 has two pad printing rubber heads 30, and can pad print different shapes of marks on two surfaces of the workpiece 200. It can be understood that when the pad printing marks of the two side surfaces of the workpiece are the same, only one pad printing rubber head 30 can be used.

[0037] The above description is a detailed description of the preferred and feasible embodiments of the utility model, but the embodiments are not used to limit the patent application range of the utility model, and any equivalent changes or modified changes completed under the technical spirit of the utility model should belong to the patent range covered by the utility model.
