Description

Technical Field

[0001] This utility model relates to the field of filter product manufacturing, and in particular to an automated device for locking screw assemblies. Background Technology

[0002] In the existing filter product manufacturing process, in order to meet electromagnetic compatibility and electrical safety requirements, the filter module and its auxiliary electronic components are usually integrated and installed in the housing, and the electrical signal connection with the user equipment is realized through the terminals on the housing. To ensure the insulation performance and mechanical stability of the terminal connection, insulating pads, gaskets and other components need to be placed on the terminal surface in sequence, and finally the nut is tightened to complete the fixation; Currently, this assembly process generally relies on manual operation, with operators manually performing a series of actions such as positioning the insulating sheet, placing the gasket, and tightening the nut. This manual operation mode is significantly affected by the operator's skill level and fatigue, resulting in a long assembly time for a single product. It is difficult to match the cycle time requirements of automated production lines, becoming a bottleneck restricting the large-scale and efficient production of filter products.

Furthermore, the turntable motor drives the disc body 21 to rotate intermittently in equal-angle increments. The single rotation angle of the disc body 21 is 60°, so that each fixture 22 passes through the loading area, four assembly areas and unloading area in sequence. When the disc body 21 stops rotating, two of the fixtures 22 are located in the loading area and unloading area respectively, and the other four fixtures 22 are located in the four assembly areas respectively.

The housing 23 to be assembled is placed in the fixture 22 in the loading area, and one end of the terminal 231 is placed in the limiting groove 221. The housing 23 is constrained on the fixture 22 by the cooperation between the limiting groove 221 and the terminal 231. After the housing 23 is assembled and transferred to the unloading area, the terminal 231 is disengaged from the limiting groove 221 by lifting the housing 23, thereby removing the housing 23 from the fixture 22.

[0026] Please refer to Figures 1-7 .

Furthermore, the width of the feeding channel 311 is greater than the width of the material, but less than the width of two materials side by side, so that when the vibrating plate 31 pushes multiple materials into the feeding channel 311, the multiple materials are arranged in a line in the feeding channel 311, and gradually move to the other end of the feeding channel 311 under the continuous feeding of the vibrating plate 31.

Furthermore, the material trough 331 is located at the edge of the material plate 33, so that an opening is formed on one side of the material trough 331, which facilitates the feeding channel 311 to push the material into the material trough 331 through the opening; both sides of the material trough 331 are provided with recesses, and when the first gripper 423 grips the material in the material trough 331, the two gripping arms of the first gripper 423 can respectively extend into the recesses on both sides of the material trough 331, which facilitates the first gripper 423 to grip the material; Furthermore, a feeding cylinder 321 is fixedly connected to the mounting base 32.

The output shaft of the feeding cylinder 321 and the sliding path of the material plate 33 on the mounting base 32 are parallel to each other. During operation, the output shaft of the feeding cylinder 321 drives the material plate 33 to reciprocate on the mounting base 32, causing the two material troughs 331 to approach and align with the other end of the feeding channel 311 in sequence, thereby allowing the feeding channel 311 to push the material into the currently aligned material trough 331. Subsequently, the output shaft of the feeding cylinder 321 drives the material plate 33 to move to the center position. At this time, the outlet of the feeding channel 311 is located between the two material troughs 331, and the material in the feeding channel 311 touches the outer wall of the material plate 33, completing the placement of the material into the material trough 331 of the material plate 33. After the material in the material trough 331 is removed, the output shaft of the feeding cylinder 321 drives the material plate 33 to repeat the above steps for the next feeding.

Furthermore, a first gripper 423 is slidably connected to the clamping assembly 42, and the first gripper 423 is fixedly connected to the clamping slide plate 421. In this embodiment, it is preferable that there are two first grippers 423 on the clamping slide plate 421. The two first grippers 423 are symmetrical to each other and have the same height. The distance between the two first grippers 423 is equal to the distance between the two material slots 331. The traveling assembly 41 drives the first grippers 423 to travel back and forth between the material plate 33 of the feeding mechanism 3 and the assembly area.
