Description

Technical Field

[0001] This utility model relates to the field of correction technology, and in particular to paper correction actuators. Background Technology

[0002] In the printing industry, the process of dividing large sheets of printing into smaller sheets is called sheet sorting. The positioning of the paper is very important during sheet sorting, and the straight cut is related to whether the finished sheets are neatly divided. In traditional processes, before sheet sorting, the paper is usually corrected manually or by actuators such as cams and linkages. However, actuators such as cams and linkages have poor load capacity or response accuracy, and it is also difficult to make them smaller. During the manual correction and transfer process, paper deformation and other adverse factors can easily occur, which will affect the overall sheet sorting quality and cause losses. In order to address the above-mentioned defects, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a paper correction mechanism that works in conjunction with a vision positioning module to perform paper correction actions. It has high correction accuracy and solves the problem that manual correction can easily lead to paper deformation and other defects.

[0004] To solve the above problems, this utility model provides a paper correction actuator, including a translation module and a clamping module. The translation module includes a motor, a lead screw, a slide table, and a slider. The motor is connected to the lead screw, and the slider is mounted on the slide table and connected to the lead screw. The lead screw mechanism has the advantages of high precision, strong load capacity, and fast response. The clamping module includes a bracket, a telescopic component, a gripper support, and a gripper assembly. The telescopic component and the gripper support are mounted on the bracket, and the bracket is connected to the slider. The gripper assembly includes a fixed gripper and a movable gripper that are hinged together. The movable gripper is hinged to the telescopic component. The fixed claw is used to drive the movable claw to switch between clamping and releasing states. The fixed claw is provided with a positioning groove, and the claw support is provided with a mating groove. The positioning groove and the mating groove cooperate to make the fixed claw snap onto the claw support. The clamping surface of the fixed claw is set horizontally. In the previous step, the paper is placed on the clamping surface of the fixed claw. The telescopic component drives the movable claw to cooperate with the fixed claw to clamp the paper. In the translation module, the motor drives the slider to move along the slide table, so that the claw assembly moves the paper to correct the deviation. The translation amount of the slider is determined by the paper offset detected by the vision positioning module.

[0005] The gripping surfaces of the gripper assembly are all flat, and when not gripping, the gripping surface of the fixed gripper is horizontal, so that the paper will not be deformed during the gripping process.

[0006] According to one embodiment of the present invention, the translation module further includes a limit sensor, which is electrically connected to the motor. Two sets of limit sensors are provided and installed on the base, respectively located on the front and rear sides of the slider.

[0007] According to one embodiment of the present invention, the telescopic component includes a cylinder, the tail end of which is hinged to the bracket.

[0008] According to one embodiment of the present invention, the piston rod of the cylinder is connected to the gripper assembly via a connecting rod.

[0009] According to one embodiment of the present invention, the movable claw is provided with a connecting groove, and the fixed claw and the connecting rod are both installed in the connecting groove.

[0010] The connecting groove is formed between two plate-like structures on the movable claw. The fixed claw and connecting rod are both installed in the connecting groove, which can improve the compactness of the structure. The hinged pin is connected to the plate-like structures on both sides, which provides better stability and ensures the accuracy of the correction action.

[0011] According to one embodiment of the present invention, the translation module further includes an L-shaped base, on which the motor, lead screw and slide are all mounted, further improving the compactness of the overall structure and reducing the difficulty of arranging the structure.

[0012] According to one embodiment of the present invention, the fixed claw is provided with a protrusion, and the clamping surface of the fixed claw and the protrusion form an L-shaped structure. The protrusion extends into the connecting groove and connects with the movable claw, thereby making the clamping surface of the fixed claw horizontal.

[0013] According to one embodiment of the present invention, the motor is a servo motor.

[0014] The beneficial effects of this utility model are that when performing the correction action, the telescopic component drives the movable claw to cooperate with the fixed claw to clamp the paper, and the translation module causes the claw component to move the paper to perform correction. The translation module adopts a lead screw mechanism, which has high precision, strong load capacity, fast response and compact structure, which is conducive to the rapid and accurate execution of the correction action.

[0019] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0020] Example 1:

[0021] Paper correction mechanism, such as Figure 1 , Figure 2 It includes a translation module 1 and a clamping module 2.

[0022] The translation module 1 includes a base 16, a motor 11, a lead screw 13, a slide table 12, and a slider 15. The base 16 is L-shaped. The motor 11, lead screw 13, and slide table 12 are all mounted on the base 16, which improves the compactness of the overall structure and reduces the difficulty of arranging this structure.

[0023] The motor 11 is preferably a servo motor to ensure the accuracy of the correction execution. The motor 11 is connected to the lead screw 13. The slider 15 is mounted on the slide table 12 and connected to the lead screw 13. Two sets of limit sensors 14 are installed on the base 16 and are respectively set on the front and rear sides of the slider 15. The limit sensors 14 are electrically connected to the motor 11 and are used to limit the displacement range of the slider 15.

[0024] The clamping module 2 includes a bracket 26, a telescopic component 21, a gripper support 25, and a gripper assembly 24. The telescopic component 21 includes a cylinder, the tail end of which is hinged to the bracket 26. The gripper support 25 is fixedly mounted on the bracket 26. The bracket 26 is connected to the slider 15.

[0025] like Figure 3 The gripper assembly 24 includes a fixed gripper 242 and a movable gripper 241 that are hinged together. The piston rod of the cylinder is connected to the movable gripper 241 through a connecting rod 23. The telescopic assembly 21 is used to drive the movable gripper 241 to switch between gripping and releasing states.

[0026] The movable claw 241 is provided with a connecting groove 244. The fixed claw 242 and the connecting rod 23 are both installed in the connecting groove 244. The connecting groove 244 is formed between two plate-like structures on the movable claw 241. The fixed claw 242 and the connecting rod 23 are both installed in the connecting groove 244, which can improve the compactness of the structure. Moreover, the hinged pin is connected to the plate-like structures on both sides, which provides better stability and ensures the accuracy of the correction action.

[0027] The fixed claw 242 is provided with a protrusion 245. The clamping surface of the fixed claw 242 and the protrusion 245 form an L-shaped structure. The protrusion 245 extends into the connecting groove 244 and connects with the movable claw 241, thereby making the clamping surface of the fixed claw 242 horizontal.

[0028] The fixed claw 242 is provided with a positioning groove 243, and the gripper support 25 is provided with a mating groove 251. The positioning groove 243 and the mating groove 251 are interlocked and fitted together, so that the fixed claw 242 is snapped onto the gripper support 25. The clamping surface of the fixed claw 242 is set horizontally to avoid paper deformation during clamping.

[0029] In the preceding steps, the paper is placed on the clamping surface of the fixed claw 242. The telescopic component 21 drives the movable claw 241 to cooperate with the fixed claw 242 to clamp the paper. In the translation module 1, the motor 11 drives the slider 15 to move along the slide table 12, so that the claw component 24 moves the paper to correct the deviation. The translation amount of the slider 15 is determined by the paper offset detected by the vision positioning module.

[0030] The clamping surfaces of the gripper assembly 24 are all flat, and when not clamping, the clamping surface of the fixed claw 242 is horizontal, so that the paper will not be deformed during the clamping process.

[0031] The paper alignment system includes the aforementioned paper alignment actuator and vision positioning module. The vision positioning module is electrically connected to the motor 11 and is used to determine the paper offset. The vision positioning module can be a camera module, such as using visual inspection of the printing Mark cross coordinates to guide the paper alignment actuator, thereby correcting the paper position, ensuring accurate card sorting, and reducing defects.

[0032] When the paper correction actuator is used, it is used in conjunction with the carrier platform. The carrier platform has a slot for accommodating the gripper assembly 24. The clamping surface of the fixed claw 242 is flush with the surface of the carrier platform. The carrier platform is used to carry the paper. After the gripper assembly 24 clamps the material, it moves in the slot to correct the paper's deviation.

[0033] Multiple sets of paper correction actuators can be optionally configured.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
