[0001] This utility model relates to an automatic assembly device for the pull rod assembly of a trolley case, and more particularly to an automatic transfer device for the pull rod. Background Technology

[0002] Suitcase handle assemblies typically come in two specifications: two-section and three-section. Two-section handles have one fewer section than three-section handles. Three-section handles are suitable for small suitcases, ensuring sufficient handle length, while two-section handles are suitable for large suitcases. A two-section handle assembly includes a small handle and a large handle that are sequentially connected, a buckle at the end of the small handle, a spring pin and an inner tube sleeve, a gantry frame mounted on the small handle, a handle at the top of the small handle, and a movable top rod located inside the small handle. The large handle is fixed to the suitcase body.

[0003] The current assembly process is all done manually, which is inefficient. However, if we want to automate the assembly process, the tie rods need to be fixed on the assembly line for circulation. Therefore, how to achieve both fixing and circulation on the assembly line is an urgent problem to be solved. Utility Model Content

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1 to 6 As shown, an automatic transfer device for pull rods includes a double-speed chain 30, a stopping device 109, a pull rod clamping device, a top-clamping device, a clamping drive device, and a release drive device. The stopping device 109 is mounted on the double-speed chain 30. The pull rod clamping device is movably positioned on the double-speed chain 30, and the double-speed chain 30 drives the pull rod clamping device to move, clamping the pull rod. The clamping drive device is mounted on the pull rod clamping device to keep the pull rod clamped and to provide clamping force during movement. The top-clamping device is mounted on the double-speed chain 30 and corresponds one-to-one with the stopping device 109, used to lift the pull rod clamping device and separate it from the chain of the double-speed chain 30 for easy assembly. The release drive device is mounted on the double-speed chain 30 and located on one side of the top-clamping device, used to drive the clamping drive device to push the pull rod clamping device to release the pull rod. The stopping device 109 is used to stop the pull rod clamping device at the corresponding workstation.

[0017] The pull rod clamping device is used to clamp the pull rod. The double-speed chain 30 drives the pull rod clamping device to move at each station. The stopping device 109 stops the pull rod clamping device at the corresponding station. The tightening device lifts the pull rod clamping device to separate it from the chain of the double-speed chain 30, preventing it from slipping on the chain and improving assembly stability. Overall, it realizes the automatic flow of pull rods, improves assembly efficiency, and provides a foundation for automated assembly.

[0018] The pull rod clamping device includes a clamping base plate 101, a first pneumatic gripper 102, and a first fixed gripper 103. The clamping base plate 101 is a rectangular plate, and the first pneumatic gripper 102 is mounted on the clamping base plate 101. To improve assembly efficiency, two first pneumatic grippers 102 are provided, symmetrically located on both sides of the center line of the clamping base plate 101. The first pneumatic grippers 102 are vertically arranged and mounted on the clamping base plate 101 via a first clamping connecting plate 1021. The first fixed gripper 103 is mounted on the first pneumatic gripper 102 and is located in a first fixed clamping groove 1031 that matches the pull rod. The pull rod is clamped within the first fixed clamping groove 1031. The first fixed gripper 103 improves the stability of the pull rod after clamping and improves the accuracy of the pull rod position.

[0019] To ensure the lever clamping device maintains clamping on the lever during movement and to address the issue of the first pneumatic gripper 102 failing to maintain clamping when the device is neither powered nor pneumatic, a clamping drive device is specifically designed, comprising a clamping rod 181 and a clamping spring 182. One end of the clamping rod 181 is threaded onto the piston rod of the first pneumatic gripper 102, and the clamping rod 181 extends flexibly through the bottom of the first pneumatic gripper 102. The two ends of the clamping spring 182 abut against the other end of the clamping rod 181 and the bottom of the first pneumatic gripper 102, respectively. The clamping spring 182, through the clamping rod 181, drives the piston rod of the first pneumatic gripper 102 to move, causing the two first fixed grippers 103 on the first pneumatic gripper 102 to clamp the lever. The clamping spring 182 is a cylindrical compression spring. To protect the first pneumatic gripper 102, the clamping drive device also includes an annular gasket 183. The annular gasket 183 is located at the bottom of the first pneumatic gripper 102 and is movably inserted into the clamping rod 181. One end of the clamping spring 182 abuts against the annular gasket 183.

[0020] The release drive device includes a release cylinder 1042 and a release rod 1041. The release cylinder 1042 is mounted on the conveyor frame 301 of the double-speed chain 30 via a release connecting plate. The release rod 1041 is fixed to the piston rod of the release cylinder 1042 and is positioned opposite to the clamping rod 181. When the lever clamping device is above the release rod 1041, the release cylinder 1042 is pneumatically activated, causing the release rod 1041 to push against the clamping rod 181. The clamping rod 181 moves upward, and the first pneumatic gripper 102 drives the first fixed gripper 103 to move to both sides, thereby releasing the lever. The release drive device can be installed at appropriate workstations as needed, and does not need to be installed at every workstation.

[0021] The clamping device includes a clamping cylinder 1051, a clamping base 1052, clamping columns 1053, and a clamping pressure rod 17. The clamping cylinder 1051 is fixed on the conveyor frame 301 of the double-speed chain 30. The clamping cylinder 1051 is a multi-axis cylinder. The piston rod of the clamping cylinder 1051 is connected to the clamping base 1052. The clamping base 1052 is located between the two chains of the double-speed chain 30. Four clamping columns 1053 are mounted on the top of the clamping base 1052. The clamping columns 1053 are arranged in an array and are located at the four corners of the clamping base 1052. The clamping pressure rod 17 is fixed on the outside of the conveyor frame 301 of the double-speed chain 30 and is located on both sides of the conveyor frame 301. The clamping pressure rod 17 is also located on the clamping base plate 10. At both ends of 1, that is, at the two opposite corners of the clamping base plate 101, the clamping pressure rod 17 is L-shaped and is set opposite to the chain of the speed-multiplying chain 30, that is, opposite to the clamping base plate 101 of the pull rod clamping device. When the clamping cylinder 1051 drives the clamping base 1052 and the clamping column 1053 to rise onto the clamping base plate 101, and drives the clamping base plate 101 to rise until the clamping base plate 101 abuts against the clamping pressure rod 17, the clamping base plate 101 is fixed, that is, the pull rod clamping device is fixed, so that the clamping base plate 101 is separated from the chain of the speed-multiplying chain 30, so that the pull rod clamping device maintains a stable state and is not affected by the chain of the speed-multiplying chain 30, which facilitates the precise assembly of other parts. To reduce the stroke of the clamping cylinder 1051 and improve stability, the clamping device also includes a clamping block 171, which is located on the top of the clamping base plate 101 and at two opposite corners of the clamping base plate 101. The clamping block 171 is arranged opposite to the clamping pressure rod 17. The clamping block 171 reduces the distance between the clamping base plate 101 and the clamping pressure rod, thereby reducing the stroke of the clamping cylinder 1051.

[0022] A clamping pin 1054 is also provided on the clamping column 1053. The clamping pin 1054 is positioned opposite the clamping positioning hole 1014 on the clamping base plate 101. There are two clamping pins 1054, located on the clamping columns 1053 at two opposite corners of the clamping base 1052. The top of the clamping pin 1054 is conical, which facilitates insertion into the clamping positioning hole 1014 to improve the positioning accuracy of the clamping base plate 101. The diameter of the clamping pin 1054 is smaller than the diameter of the clamping column 1053, forming a stepped shaft, which facilitates stable lifting of the clamping base plate 101.

[0023] The stopping device 109 includes a stopping cylinder 1091, a stopping block 1092, and a stopping sensor. The stopping cylinder 1091 is fixed to the conveyor frame 301 of the double-speed chain 30. The stopping block 1092 is fixed to one end of the clamping base plate 101 and located at a corner. When the piston rod of the stopping cylinder 1091 extends, it blocks the stopping block 1092, causing the clamping base plate 101 to slide on the double-speed chain 30 and stop. The stopping sensor is installed on the conveyor frame 301 of the double-speed chain 30 and is positioned opposite the clamping base plate 101 or the stopping block 1092. It is used to detect the clamping base plate 101 or the stopping block 1092 and then send an extension command to the stopping cylinder 1091, causing the stopping cylinder 1091 to start. The stopping sensor can be a photoelectric sensor or a proximity switch, and is fixed to the conveyor frame 301 of the double-speed chain 30 via a sensor bracket 1093.
