Description

Technical Field

[0001] This invention relates to the field of workstation technology, and in particular to an armature assembly workstation. Background Technology

[0002] The armature assembly is a crucial component in the actuation mechanism, providing structural support, positioning, and protection. During its production, the armature, pyrotechnic components, and top cover must be precisely assembled. Traditionally, manual loading and unloading are used, which suffers from low positioning accuracy, poor assembly consistency, low work efficiency, and safety hazards related to pyrotechnic components. Therefore, a high-precision, fully automated assembly station needs to be designed to improve production efficiency and isolate hazardous processes from human intervention. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an armature assembly workstation to solve the problems of low positioning accuracy, poor assembly consistency and low work efficiency in armature assembly.

[0004] To address the existing technical problems, the technical solution adopted in this invention is as follows: an armature assembly workstation, comprising a frame, a three-axis robotic arm, an automatic screw mechanism, and a pressing mechanism. The three-axis robotic arm, the automatic screw mechanism, and the pressing mechanism are sequentially mounted on the frame. A loading tray is provided on the frame, on which an armature, a pyrotechnic workpiece, and a top cover are placed. The three-axis robotic arm places the armature onto the worktable of the frame, places the pyrotechnic workpiece into the armature, and the pressing mechanism presses the pyrotechnic workpiece and the armature together. The three-axis robotic arm places the top cover onto the armature, and the automatic screw mechanism automatically tightens the top cover and the armature with screws.

[0005] Furthermore, the frame of the present invention is equipped with a track, and a slider is slidably arranged on the track. The three-axis robotic arm places the armature on the slider, and then places the pyrotechnic workpiece into the armature. The slider then slides to the pressing mechanism, which presses the pyrotechnic workpiece and the armature together. Then, the slider slides to the automatic screw mechanism, and the three-axis robotic arm places the top cover on the armature. The automatic screw mechanism automatically tightens the top cover and the armature with screws.

[0006] Furthermore, the frame of the present invention is equipped with a rotary table positioning and transferring mechanism, which includes an indexing rotary table, a turntable, and armature positioning fixtures. The indexing rotary table is located in the middle of the frame, and the turntable is installed at the output end of the indexing rotary table. Armature positioning fixtures are evenly arranged circumferentially on the turntable surface. Each set of fixtures has a positioning slot adapted to the outer contour of the armature, and anti-slip rubber pads are embedded in the slots. The indexing rotary table divides the turntable circumferentially into a feeding station, a workpiece pressing station, and a workpiece pressing station. The system consists of four independent work areas: the top cover locking station, the unloading station, and the top cover locking station. At the loading station, a three-axis robotic arm places the armature onto the armature positioning fixture. Then, the pyrotechnic workpiece is placed into the armature. The turntable then rotates to the pyrotechnic workpiece pressing station, where the pressing mechanism presses the pyrotechnic workpiece onto the armature. Next, the turntable rotates to the top cover locking station, where the three-axis robotic arm places the top cover onto the armature. An automatic screw mechanism automatically tightens the top cover and armature with screws. Finally, the turntable rotates to the unloading station to remove the armature from the tightened top cover.

[0007] Furthermore, the end of the three-axis robotic arm described in this invention is equipped with a parallel pneumatic gripper, which is used to clamp the armature and the top cover.

[0008] Furthermore, the end of the three-axis robotic arm described in this invention is equipped with a precision pneumatic gripper, which is used to clamp pyrotechnic workpieces.

[0009] Furthermore, the pressing mechanism of the present invention includes a bracket and a pressing cylinder. The bracket is fixed on the frame, and the pressing cylinder is mounted on the bracket. The movable end of the pressing cylinder can push the pyrotechnic workpiece.

[0010] Beneficial effects This invention achieves fully automated operation of pressing and assembling the armature and top cover. It uses a three-axis robotic arm for automatic feeding, a pressing mechanism to press the pyrotechnic workpiece, and an automatic screw mechanism to assemble the armature and top cover. This replaces traditional manual pressing and simple clamping operations, effectively reducing the intensity of manual labor and significantly improving the assembly production efficiency of the armature assembly.

[0013] The invention will be further described below with reference to the accompanying drawings.

[0014] An armature assembly workstation, for the purpose of facilitating automatic feeding, includes a frame 1, a feeding tray 2 on the frame 1, an armature 3, a pyrotechnic workpiece 4 and a top cover 5 placed on the feeding tray 2; The frame 1 is equipped with a three-axis robotic arm 6, which can grasp the armature 3, the pyrotechnic workpiece 4, or the top cover 5. A track 7 is installed on the frame 1, and a slider 8 is slidably mounted on the track 7. The three-axis robotic arm 6 can place the armature 3 onto the slider 8 and place the pyrotechnic workpiece 4 into the armature 3. The slider 8 can slide under the pressing mechanism 12, and the pressing mechanism 12 can press the pyrotechnic workpiece 4 and the armature 3 together. To facilitate the assembly of the armature 3 and the pressure cap, an automatic screw mechanism 9 is also installed on the frame 1. The slider 8 can slide under the automatic screw mechanism 9, the three-axis robotic arm 6 can place the top cover 5 on the armature 3, and the automatic screw mechanism 9 can automatically tighten the top cover 5 and the armature 3 with screws.

[0015] To facilitate gripping the armature 3 and the top cover 5, a parallel pneumatic gripper 10 is installed at the end of the three-axis robotic arm 6. The parallel pneumatic gripper 10 can clamp the armature 3 and the top cover 5.

[0016] To facilitate the gripping of the pyrotechnic workpiece 4, a precision pneumatic gripper 11 is installed at the end of the three-axis robotic arm 6. The precision pneumatic gripper 11 can clamp the pyrotechnic workpiece 4.

[0017] In order to facilitate the pressing of the pyrotechnic workpiece 4, the pressing mechanism 12 includes a bracket 13 and a pressing cylinder 14. The bracket 13 is fixed on the frame 1, and the pressing cylinder 14 is installed on the bracket 13. The movable end of the pressing cylinder 14 can push the pyrotechnic workpiece 4.

[0018] The rotary table positioning and material transfer mechanism replaces the original linear slide rail slider material transfer structure. A dividing rotary table is set in the middle of the frame, and a turntable is installed at the output end of the dividing rotary table. Four sets of armature positioning fixtures are evenly arranged around the circumference of the turntable surface. Each set of fixtures has a positioning slot that matches the outer contour of the armature. Anti-slip rubber pads are embedded in the slots, which is much more accurate than the positioning of linear slide rail material transfer. The dividing rotary table divides the turntable around the circumference into four independent working areas: loading station, pyrotechnic workpiece pressing station, top cover locking station, and unloading station. The four stations can perform operations simultaneously, avoiding the cycle time waste of the original single station sequential operation.

[0019] This invention has been proven feasible after experimental use. It achieves fully automated operation of the armature and top cover pressing assembly. The three-axis robotic arm automatically feeds materials, and the pressing mechanism completes the pressing of the pyrotechnic workpiece. The automatic screw mechanism completes the assembly of the armature and top cover. It replaces the traditional manual pressing and simple clamping operations, effectively reduces the intensity of manual labor, and greatly improves the assembly production efficiency of the armature assembly.

[0020] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
