Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a carbon ribbon processing and transfer mechanism. Background Technology

[0002] Label making devices utilize thermal transfer technology. Printing material, such as toner or other colored substances, is placed on a ribbon, and the printer head directly transfers the material from the ribbon onto the printing medium. During production, the label making device requires the installation of a ribbon spool wound with the ribbon and a take-up spool into the housing. This process is typically done manually, where a certain length of ribbon is wound onto the spool, and the spool and take-up spool are then placed into their corresponding positions within the housing. However, manual operation is inefficient and does not meet the demands of modern industrial production. While robotic arms exist for material handling, they require specific positioning angles for the ribbon spool and take-up spool. Existing equipment cannot meet these requirements, and forced assembly could damage the internal positioning grooves or even the housing itself. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carbon ribbon processing material transfer mechanism that can automatically identify the placement angle of the limiting groove of the inner groove of the carbon ribbon shaft and the recycling shaft, and adjust the clamping angle according to the angle.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a workstation turntable and an assembly transfer hand. The assembly transfer hand includes a dual-axis transfer frame, a rotary cylinder, and a pneumatic gripper. The rotary cylinder is driven by the dual-axis transfer frame and can move in the horizontal and vertical directions. The pneumatic gripper is driven by the rotary cylinder and can rotate around its own axis. The workstation turntable includes a fixed bracket, a stepper motor disposed below the fixed bracket, and a turntable disposed on the top of the fixed bracket and connected to the rotating shaft of the stepper motor. Several vacuum suction stations are arranged in an array on the upper surface of the turntable. A positioning camera is disposed on the outer periphery of the fixed bracket. The positioning camera is located directly above the vacuum suction station and is electrically connected to the dual-axis transfer frame and the rotary cylinder.

[0005] Furthermore, the vacuum suction station includes a vacuum base, a vacuum connector disposed on the end face of the vacuum base facing the center of the turntable, and a fixed column vertically disposed on the vacuum base. Several vacuum suction holes are also disposed around the fixed column on the upper end face of the vacuum base. The vacuum suction holes are connected to the vacuum connector. A high-speed rotating air receiving head is also disposed at the center of the turntable. The high-speed rotating air receiving head is connected to the vacuum connector.

[0006] Furthermore, an infrared sensor is also provided on the outer periphery of the fixed bracket, and the infrared sensor is connected to the outer end of the vacuum suction station side face through an L-shaped bracket.

[0007] Furthermore, a position trigger is provided on the upper surface of the fixed bracket, and a trigger piece adapted to the position trigger is provided on the turntable at any of the vacuum suction stations.

[0008] Furthermore, the dual-axis transfer frame includes a gantry frame disposed on the outer periphery of the workstation turntable, a horizontal cylinder horizontally disposed on the top of the gantry frame, a horizontal slider fixedly connected to the output rod of the horizontal cylinder, and a vertical cylinder fixedly disposed on the horizontal slider. The rotary cylinder is fixedly disposed on the output shaft of the vertical cylinder. The pneumatic gripper is connected to the rotation shaft of the rotary cylinder. A slide rail is also disposed on the top of the gantry frame, and the horizontal slider is slidably connected to the slide rail.

[0009] Furthermore, a spring limiter is also provided on the slide rail at the other end corresponding to the horizontal cylinder.

[0010] Finally, the pneumatic gripper includes a gripping cylinder and a first gripping block and a second gripping block driven by the gripping cylinder. The outer surfaces of the first gripping block and the second gripping block are designed with convex arc surfaces.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a rotary rotating material transfer method to replace traditional assembly line transmission, effectively saving equipment space; it uses vacuum adsorption instead of mechanical clamping to fix the carbon ribbon shaft, avoiding damage such as wrinkling to the outer surface of the carbon ribbon during processing and clamping; the positioning camera located above the vacuum suction station records the specific position of the carbon ribbon shaft placed at the vacuum suction station and the orientation of the limiting groove on the inner side of the carbon ribbon shaft, and transmits the information to the dual-axis transfer frame and the rotary cylinder to control the movement path and final clamping position of the pneumatic gripper, and adjusts the angle of the pneumatic gripper through the rotary cylinder, facilitating the subsequent assembly of the carbon ribbon shaft into the housing of the label making device, and avoiding damage to the limiting groove on the inner side of the carbon ribbon shaft. Therefore, this invention can automatically identify the placement angle of the carbon ribbon shaft and the limiting groove of the recycling shaft, and adjust the clamping angle accordingly.

[0019] like Figures 1 to 7 As shown, this utility model includes a workstation turntable 1 and an assembly transfer hand 2. The assembly transfer hand 2 includes a dual-axis transfer frame, a rotary cylinder 21, and a pneumatic gripper 22. The rotary cylinder 21 is driven by the dual-axis transfer frame and can move in the horizontal and vertical directions. The pneumatic gripper 22 is driven by the rotary cylinder 21 and can rotate around its own axis. The workstation turntable 1 includes a fixed bracket 10, a stepper motor 11 disposed below the fixed bracket 10, and a turntable 12 disposed on the top of the fixed bracket 10 and connected to the rotating shaft of the stepper motor 11. Several vacuum suction stations are arranged in an array on the upper surface of the turntable 12. A positioning camera 13 is disposed on the outer periphery of the fixed bracket 10. The positioning camera 13 is located directly above the vacuum suction station and is electrically connected to the dual-axis transfer frame and the rotary cylinder 21. This invention uses a rotary transfer method to replace traditional assembly line transport, effectively saving equipment space. Vacuum adsorption replaces mechanical clamping to fix the carbon ribbon shaft, avoiding damage such as wrinkling to the outer surface of the carbon ribbon during processing and clamping. The positioning camera 13, located above the vacuum suction station, records the specific position of the carbon ribbon shaft placed at the vacuum suction station and the orientation of the limiting groove on the inner side of the carbon ribbon shaft. This information is transmitted to the dual-axis transfer frame and the rotary cylinder 21 to control the movement path and final clamping position of the pneumatic gripper 22. The rotary cylinder 21 adjusts the angle of the pneumatic gripper 22 to facilitate subsequent assembly of the carbon ribbon shaft into the housing of the label making device, preventing damage to the limiting groove 3 on the inner side of the carbon ribbon shaft.

[0020] In this utility model, the vacuum suction station includes a vacuum base 14, a vacuum connector 15 disposed on the end face of the vacuum base 14 facing the center of the turntable 12, and a fixing column 16 vertically disposed on the vacuum base 14. A plurality of vacuum suction holes 17 are also disposed around the fixing column 16 on the upper end face of the vacuum base 14. The vacuum suction holes 17 are connected to the vacuum connector 15. A high-speed rotating air receiving head 18 is also disposed at the center of the turntable 12. The high-speed rotating air receiving head 18 is connected to the vacuum connector 15. The high-speed rotating air inlet 18 is connected to the turntable 12 via a rotating bearing, so that when the turntable 12 rotates, the high-speed rotating air inlet 18 will not rotate with it, thus avoiding damage to the external air pump. The high-speed rotating air inlet 18 has a number of air outlets that match the number of vacuum connectors 15 on its outer periphery. Several vacuum suction holes 17 are located close to the fixing post 16. When the carbon ribbon shaft is fitted into the fixing post 16, the vacuum suction holes 17 are all located inside the carbon ribbon shaft. During fixing, a vacuum area is formed inside the carbon ribbon shaft to stably adsorb the carbon ribbon shaft.

[0021] An infrared sensor 19 is also provided on the outer periphery of the fixed bracket 10. The infrared sensor 19 is connected to the outer end of the vacuum suction station side face via an L-shaped bracket 100. A position trigger 101 is provided on the upper end face of the fixed bracket 10. A trigger piece 102 adapted to the position trigger 101 is provided on the turntable 12 at the position corresponding to any of the vacuum suction stations. The infrared sensor 19 determines whether a carbon ribbon shaft is adsorbed at the vacuum suction station; the trigger piece 102 rotates with the turntable 12 and passes through the position trigger 101 multiple times, recording the number of rotations and rotation rhythm of the turntable 12.

[0022] In this utility model, the dual-axis transfer rack includes a gantry frame 23 disposed on the outer periphery of the workstation turntable 1, a horizontal cylinder 24 horizontally disposed on the top of the gantry frame 23, a horizontal slider 25 fixedly connected to the output rod of the horizontal cylinder 24, and a vertical cylinder 26 fixedly disposed on the horizontal slider 25. A rotary cylinder 21 is fixedly disposed on the output shaft of the vertical cylinder 26. The pneumatic gripper 22 is connected to the rotation shaft of the rotary cylinder 21. A slide rail 27 is also disposed on the top of the gantry frame 23. The horizontal slider 25 is slidably connected to the slide rail 27. The positioning camera 13 determines the specific position of the carbon ribbon shaft. The movement trajectory of the pneumatic gripper 22 is controlled by the horizontal cylinder 24 and the vertical cylinder 26, and the gripper is moved to the final gripping position. The rotary cylinder 21 rotates according to the specific orientation of the limiting groove 3 inside the carbon ribbon shaft, adjusting the rotation angle of the pneumatic gripper 22 to ensure the placement position during subsequent assembly. A spring limiter 28 is also provided on the slide rail 27 at the other end corresponding to the horizontal cylinder 24 to limit and protect the horizontal slider 25 when it moves horizontally. The pneumatic gripper 22 includes a gripping cylinder 220 and a first gripping block 221 and a second gripping block 222 driven by the gripping cylinder 220. The outer surfaces of the first gripping block 221 and the second gripping block 222 are designed with an outwardly convex arc surface 223.
