[0027] Please see Figures 1 to 3 This embodiment of an automatic capping device for ignition powder boxes is installed on an automatic assembly line for ignition powder boxes. It includes: a support plate 1, a Z-axis drive mechanism 2 disposed on one side of the support plate 1, a pneumatic chuck 3 mounted on the lifting platform of the Z-axis drive mechanism 2, a gripper mechanism 4 that is linked to and driven by the pneumatic chuck 3 to clamp the box body, a positioning mechanism 5 that is disposed through the support plate 1 and on one side of the gripper mechanism 4 to position the cap and the box body coaxially, and a tightening mechanism 6 that is connected to the positioning mechanism 4 through the support plate, descends synchronously with the lifting platform, and drives the cap to rotate and tighten onto the box body.

[0028] In a preferred embodiment, the Z-axis drive mechanism 2 includes: a fixed support frame, a Z-axis drive motor, a ball screw, a lifting platform, and a linear guide rail. One end of the fixed support frame is fixed to the support plate, the linear guide rail is mounted on the fixed support frame, the lifting platform is scalably mounted on the linear guide rail, and the ball screw is located on one side of the lifting platform. The ball screw is driven by the Z-axis drive motor. Specifically, the Z-axis drive motor is a servo motor, and its output end is connected to the ball screw via a coupling. The ball screw is threadedly engaged with the lifting platform, and both sides of the lifting platform are slidably connected to the linear guide rail. The linear guide rail is fixed to the fixed support frame along the Z-axis. Limit sensors are respectively installed at the upper and lower limit positions of the lifting platform for precise control of the lifting stroke. More specifically, the Z-axis drive mechanism 2 operates according to the drive information transmitted by the controller on the automatic assembly line for ignition cartridges.

[0029] The pneumatic chuck 3 is mounted on the lifting platform and includes: a chuck body 31, a cylinder mounted on the chuck body, pneumatic fingers 32 on one side of the chuck body 31, two jaws 33 connected to the pneumatic fingers 32, and a pressure regulating valve on the chuck body 31 connected to the air circuit of the cylinder. Specifically, the inner sides of the two jaws 33 are provided with arc-shaped clamping surfaces, and wear-resistant pads are attached to the surface of the arc-shaped clamping surfaces. In this embodiment, the wear-resistant pads are wear-resistant rubber pads, used to increase clamping friction and avoid damage to the housing. The pressure regulating valve is connected to the air circuit of the cylinder and can adjust the clamping force of the jaws 33.

[0030] The gripper mechanism 4 in this embodiment includes: at least two symmetrically arranged gripping blocks 41 driven by the pneumatic fingers 32 of the pneumatic chuck 3, and a positioning protrusion 42 located at the bottom of the groove of the gripping block. Specifically, the gripping blocks 41 are connected to the grippers 33. The cylinder drives the two gripping blocks 41 via the pneumatic fingers to move the positioning protrusion 42 to clamp or release the box body. The positioning protrusion 42 positions the box body corresponding to the positioning hole.

[0031] The tightening mechanism 6 includes: a rotary drive motor 61 located at one end of the positioning mechanism 5; a capping head 63 connected to the rotary drive motor 61 via a reduction gearbox 62; and a torque sensor located inside the capping head. A portion of the positioning mechanism 5 extends through the capping head 63. In this embodiment, the positioning mechanism 5 includes: a positioning pin extending through the capping head 61; a sensor located beside the gripper mechanism 4 to sense whether the box has reached the capping position; and a fine-tuning cylinder connected to the gripper mechanism 4. Specifically, the output end of the fine-tuning cylinder is connected to the clamping block 41. The position of the clamping block 41 is finely adjusted by extending and retracting the fine-tuning cylinder to compensate for positional deviations during the box's transport process. The slot at the top of the cap is positioned by the positioning pin. The transmission ratio of the reduction gearbox 62 is set to 1:5-1:10. During operation, the Z-axis drive mechanism 2 lowers the tightening shaft, and the capping head 63 engages with the slot on the top of the cap. The rotary drive motor 61 (servo motor) starts, driving the capping head 63 to rotate via the reduction gearbox 62. Simultaneously, the pneumatic chuck 3 drives the clamping box to rotate synchronously with the capping head 63. The torque sensor collects the tightening torque in real time. When the torque reaches the preset value, the servo motor stops rotating, and the tightening shaft rises with the Z-axis drive mechanism 2, completing the tightening action. It should be noted that the positioned cap, box, and tightening shaft are coaxial.

[0032] The working principle of this utility model is as follows:

[0033] During loading, the box body moves along the annular guide rail to the capping station. The loading grippers on the production line place the box body and the cap body onto the gripper mechanism 4 and the positioning mechanism 5, respectively. At this time, the bottom hole of the cap body engages with the positioning pin of the positioning mechanism 5 to complete the cap body positioning. The pneumatic fingers drive the clamping block to close, and the groove of the clamping block fits against the side wall of the box body to complete the box body fixing and clamping. Then, the Z-axis drive mechanism 2 drives the pneumatic chuck 3 to descend synchronously with the tightening shaft. The jaws of the pneumatic chuck close to clamp the box body, and at the same time, the capping head 63 of the tightening shaft engages with the top slot of the cap body to ensure that the cap body, the tightening shaft, and the box body are coaxial. Further, the servo motor of the tightening shaft starts, driving the capping head 63 to rotate through the reduction gearbox 62, driving the cap body to tighten with the box body; the torque sensor monitors the torque in real time. When the preset value is reached, the servo motor stops, and the tightening is completed. After that, the reset and unloading operation begins.

[0034] Reset and unloading: Pneumatic chuck 3 releases the box body, and gripper mechanism 4 releases the box body; tightening shaft and pneumatic chuck 3 rise and reset; conveying mechanism starts, transporting the tightened medicine box to the next process, completing one automatic capping cycle.

[0035] As can be seen from the above description, this utility model has the advantages of high tightening and assembly precision, effectively improving production efficiency and reducing the risk of manual operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
