[0029] This utility model proposes a printing press 100.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 In one embodiment of this utility model, the printing machine 100 includes a machine base 1, a pad printing fixture 2, a feeding mechanism 3, a correction mechanism 4, and a controller; the machine base 1 has a feeding area 11; the pad printing fixture 2 has a placement area 21 for placing workpieces, and the pad printing fixture 2 is movably disposed on the machine base 1 along a first direction; the feeding mechanism 3 is located in the feeding area 11, and the feeding mechanism 3 includes a robotic arm assembly 31 and a feeding assembly 32, the robotic arm assembly 31 being used to transfer workpieces from the feeding assembly 32 to the pad printing fixture 2; the correction mechanism 4 is located in the feeding area 11, and the… The correction mechanism 4 includes a lifting correction component 41 and a detection component 42; the detection component 42 is located above the feeding mechanism 3, and is used to detect the workpiece on the feeding component 32 and generate a first signal; the lifting correction component 41 is located below the feeding component 32, and is used to adjust the position of the workpiece to correct the workpiece on the feeding component 32; the controller is electrically connected to the detection component 42 and the lifting correction component 41 respectively, and is used to receive the first signal and control the lifting correction component 41 to adjust the position of the workpiece.

[0031] The technical solution of this utility model uses a detection component 42 to detect the workpiece on the feeding component 32 and feed back a first signal to the controller. The controller controls the lifting and correction component 41 to adjust the position of the workpiece on the feeding component 32 according to the first signal, so as to ensure that the workpiece is accurately positioned in the placement space of the feeding component 32, thereby making it easier for the robot arm component 31 to grip the workpiece and thus improving the handling efficiency of the robot arm component 31.

[0032] In this embodiment, the feeding assembly 32 may include a carrier 323, which has multiple placement spaces for placing workpieces. The carrier 323 also has multiple protrusions, with at least three protrusions spaced apart around the placement spaces to form a placement space. The at least three protrusions can be used to limit the workpiece. A gap may be formed between the at least three protrusions in a single placement space, which facilitates the gripper assembly 31 in gripping the workpiece. This application uses a detection assembly 42 to detect the workpiece on the feeding assembly 32. The detection assembly 42 can generate a first signal by calibrating the positional relationship between the contour and features on the workpiece surface and the placement space, and feed it back to the controller (not shown). The controller controls the lifting and correction assembly 41 to correct the position of the corresponding workpiece according to the first signal, so that the workpiece is more accurately located in the placement space, which facilitates the gripper assembly 31 in gripping and transporting, thereby improving the workpiece transport efficiency of the robot assembly 31. The robotic arm assembly 31 transports the workpiece to the pad printing fixture 2. The pad printing fixture 2 moves the workpiece from the loading area 11 to the printing area, making it easier for the workpiece to complete subsequent processing.

[0034] In this embodiment, the first drive assembly 412 is mounted on the machine base 1 via the first mounting bracket 411. The first drive assembly 412 drives the lifting member 413, thereby improving the connection stability between the lifting member 413 and the machine base 1. Under the drive of the first drive assembly 412, the lifting member 413 can move along the first direction, thus making it easier for the lifting member 413 to correct the position of workpieces at different locations.

[0035] like Figure 5 As shown, the lifting component 413 includes a second drive assembly 4131, a first connecting frame 4132, and a lifting rod 4133.

[0041] In this embodiment, driven by the third drive assembly 312, the first transmission unit 3131 and the second transmission unit 3132 can rotate independently relative to the picking arm 3133, thereby facilitating the adjustment of the positional relationship between the picking arm 3133 and the workpiece on the feeding assembly 32, and further facilitating the picking arm 3133 in gripping and transporting the workpiece. The picking arm 3133 is movably mounted on the second transmission unit 3132 along the second direction, thereby facilitating the adjustment of the distance between the picking arm 3133 and the workpiece, and further facilitating the picking arm 3133 in gripping or placing the workpiece.

[0043] In this embodiment, the pneumatic finger 3137 is connected to the arm body 3134 via the second connecting frame 3136. The arm body 3134 moves along the second direction to adjust the distance between the gripping part 3135 and the workpiece, thereby facilitating the pneumatic finger 3137 in picking up and placing the workpiece. The pneumatic finger 3137 includes a third driving member (unmarked) and a gripper (unmarked). The third driving member is mounted on the second connecting frame 3136 and drives the gripper, allowing the gripper to switch between an open state and a gripping state, thus facilitating the workpiece gripping by the picking arm 3133. The third driving member can be configured as a cylinder, further facilitating the operation of the gripper.

[0045] In this embodiment, the third connecting frame 421 is used to facilitate the installation of the camera 423 and the light source 424. This application uses the fourth driving component 422 to drive the connection of the third connecting frame 421 so that the third connecting frame 421 can move along the first direction, thereby making it easier for the camera 423 to adjust the angle to detect workpieces in different areas, thereby improving the detection accuracy of the camera 423.
