Description

Technical Field

[0001] This invention relates to the field of worm gear assembly technology, and in particular to a worm gear assembly machine. Background Technology

[0002] A motor is an electric device used to wind up and unwind car seat belts. It typically consists of a DC motor, a worm gear, and a worm wheel. The worm gear is helical in shape, and the worm wheel is a gear that meshes with the worm gear. When the motor starts, it drives the worm wheel through the worm gear, thereby winding up or unwinding the seat belt.

[0003] Currently, the assembly of worm gear kits involves the cooperation between humans and machines. Machines transport materials, while workers perform screening and assembly. The level of automation is not high enough, and a complete closed-loop industrial automation production has not been formed. Summary of the Invention

[0004] The present invention aims to solve the problem of the lack of a complete industrial automation closed-loop production by providing a worm gear assembly machine. It can automatically screen the worm gear sleeves and automatically install the worm gear sleeves at both ends of the worm, thus completing the automated production of worm gear kits and ensuring product quality. This forms a complete industrial automation closed-loop production, greatly reducing the labor intensity and participation of workers.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A worm gear assembly machine includes a vibratory feeder, a transfer screening mechanism, and a waste pusher. The vibratory feeder is used to convey the worm gear sleeves to the transfer screening mechanism, which is used for screening and transferring the worm gear sleeves. The transfer screening mechanism includes an outer housing A and an outer housing B. A transfer plate is provided inside the outer housing A. A rotating cylinder is connected to one side of the transfer plate, and the rotation of the transfer plate inside the outer housing A is adjusted by the rotating cylinder. A worm gear sleeve groove A and a detection channel are reserved on the surface of the transfer plate, and the detection channel communicates with the worm gear sleeve groove A. A feed inlet, a detection port C, and a notch are preset on the surface of the outer housing A. A waste outlet, a detection port A, and a detection port B are opened on the surface of the outer housing B. A pusher cylinder is connected to one side of the waste pusher, and the movement of the waste pusher within the notch and the waste outlet is adjusted by the pusher cylinder.

[0007] Furthermore, the worm gear assembly machine also includes a gripper A, which is located above the transfer screening mechanism. The upper end of the gripper A is equipped with a cylinder G, which is used to adjust the rotation of the gripper A. The upper end of the cylinder G is equipped with a cylinder B, which is used to adjust the lifting and lowering of the gripper A. One end of the cylinder B is equipped with a cylinder H, which is used to adjust the forward and backward movement of the gripper A.

[0008] Furthermore, the worm gear assembly machine also includes a platform, on which are provided a storage slot A and a storage slot B, which are used to place rod sleeves facing different directions. One end of the platform is connected to a cylinder F, which is used to adjust the left and right movement of the platform. One end of the cylinder F is connected to a cylinder E, which is used to adjust the forward and backward movement of the platform.

[0009] Furthermore, the worm gear assembly machine also includes a clamping assembly mechanism, which includes a lifting rod, grippers, a transverse block, a driven slider, and a transverse block cylinder. The upper end of the lifting rod is connected to the lifting rod cylinder, which is used to adjust the height of the lifting rod. The driven slider is slidably disposed at both ends of the lifting rod, and an adjustment port is opened on the surface of the driven slider. Grippers B are movably disposed in the adjustment port. The grippers are rotatably connected to the transverse blocks. There are two transverse blocks, which are installed at both ends of the transverse block cylinder. The movement of the transverse blocks is adjusted by the transverse block cylinder.

[0010] Furthermore, the worm gear assembly machine also includes a conveyor belt, a hopper, a feeding belt, a chute, a waste pipe, and a waste bin. The conveyor belt is used to transport pallets on which molds are placed.

[0011] Furthermore, the feeding belt is located below the hopper, through which the rod sleeve is placed, and the feeding belt is used to transport the rod sleeve to the slide rail, through which the rod sleeve slides into the vibratory feeder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By combining the waste pusher and the fiber optic sensor, the defective and qualified products of the sleeve are screened. After the sleeve is transferred to the designated position, the qualified sleeve is picked up by the gripper A, and the unqualified sleeve is pushed into the waste port by the waste pusher.

[0014] Gripper A descends to grasp the sleeve located in the sleeve groove A. After grasping, the gripper returns to its original height and moves above the platform. It then descends again to place the sleeve in the storage slot A. The platform moves to the left, so that the storage slot B on the platform is below gripper A. Gripper A then returns to its original position to grasp the next sleeve. After grasping the sleeve, gripper A rotates to adjust the orientation of the sleeve. After adjustment, gripper A moves to place the adjusted sleeve in the storage slot B. Both storage slots A and B are equipped with fiber optic sensors on one side. When both slots have sleeves, the platform returns to above the tray, and the clamping assembly mechanism descends to clamp the two sleeves on the platform. The rod sleeve is gripped, and after gripping, the platform moves away from the tray and moves back to the front of the transfer screening mechanism. The clamping assembly mechanism descends to obtain the worm gear, and puts the rod sleeve on both ends of the worm gear. The clamping assembly mechanism rises and moves to the top of the worm gear assembly slot. Then the clamping assembly mechanism descends, and by raising the height of the lifting rod, the clamping and fixing effect of the gripper B on the rod sleeve is released. At this time, the worm gear with the rod sleeve is placed in the worm gear assembly slot. This completes the installation and position transfer of the worm gear assembly. Through the above-mentioned rod sleeve screening, worm gear assembly installation, and position transfer of each component, a complete industrial automation closed-loop production is formed.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] For reference Figure 1-5 and Figure 14 As shown, this embodiment of the invention provides a worm gear assembly machine, which includes a conveyor belt 1, a hopper 2, a feeding belt 3, a slide rail 4, a vibrating plate 5, a transfer screening mechanism 6, a waste pusher 17, a waste pipe 18, and a waste bin 19. The feeding belt 3 is located below the hopper 2 and the worm gear sleeve is placed in the hopper 2. The feeding belt 3 is used to transport the worm gear sleeve to the slide rail 4. The worm gear sleeve slides down into the vibrating plate 5 through the slide rail 4. The conveyor belt 1 is used to transport a pallet. A mold is placed on the pallet. The worm gear groove on the mold is used to place the worm gear. The length of the worm gear is greater than the worm gear groove. The worm gear kit groove is used to place the assembled worm gear kit. When the pallet moves with the conveyor belt 1 to a designated place and is detected by the sensor, the stop cylinder rises to limit the continued movement of the pallet.

[0032] The vibratory feeder 5 is used to arrange the rod sleeves in an orderly manner and convey them to the transfer screening mechanism 6. The transfer screening mechanism 6 is used for screening and transferring the rod sleeves. The transfer screening mechanism 6 includes an outer casing A7 and an outer casing B8. The outer casing A7 is provided with a transfer plate 9. A rotating cylinder is connected to one side of the transfer plate 9. The rotating cylinder adjusts the rotation of the transfer plate 9 within the outer casing A7. The surface of the transfer plate 9 has a rod sleeve groove A10 and a detection channel 11. The detection channel 11 communicates with the rod sleeve groove A10. The surface of the outer casing A7 is provided with a feed inlet 13, a detection port C12, and a notch 201. The surface of the outer casing B8 is provided with a waste outlet 16, a detection port A14, and a detection port B15. A push rod cylinder is connected to one side of the waste push rod 17. The push rod cylinder adjusts the movement of the waste push rod 17 within the notch 201 and the waste outlet 16.

[0033] In use, the vibratory plate 5 delivers the rod sleeve to the feed port 13 of the outer casing A7. The transfer plate 9 is driven to rotate by the rotating cylinder, so that the rod sleeve groove A10 of the rotated transfer plate 9 corresponds to the position of the feed port 13. The rod sleeve located in the feed port 13 is then delivered to the rod sleeve groove A10. Two fiber optic sensors are set on one side of the outer casing B8. The beams of the two fiber optic sensors pass through the detection port A14 and the detection port B15 respectively.

[0034] like Figure 9 and Figure 10 As shown, detection port A14 is used to detect the presence of the rod sleeve, and detection port B15 is used to detect the presence of the baffle in the rod sleeve. When both the rod sleeve and the baffle are present, the transfer plate 9 rotates so that the rod sleeve groove A10 on the transfer plate 9 corresponds to the position of the notch 201 on the outer casing A7. A fiber optic sensor is also provided at the detection port C12. The beam of the fiber optic sensor passes through the detection port C12 and the detection channel 11 to detect the presence of the rod sleeve. When the rod sleeve is detected, it is gripped by the gripper A20. When the rod sleeve is gripped and no rod sleeve is detected, the transfer plate 9 rotates back to the position of the rod sleeve groove A10 corresponding to the feed port 13.

[0035] Detection port A14 is used to detect the presence of the sleeve, and detection port B15 is used to detect the presence of the baffle in the sleeve. When the sleeve is present but the baffle is absent, the transfer plate 9 rotates, so that the sleeve groove A10 on the transfer plate 9 corresponds to the position of the notch 201 on the outer casing A7. A fiber optic sensor is also provided at detection port C12. The beam of the fiber optic sensor passes through detection port C12 and detection channel 11 to detect the presence of the sleeve. When the sleeve is detected, the push rod cylinder adjusts the waste push rod 17 to move towards the outer casing B8. One end of the waste push rod 17 moves from the notch 201 to the position of the sleeve groove A10, thereby pushing the defective product, that is, the sleeve without the baffle, from the sleeve groove A10 to the position of the waste port 16. The defective product falls from the waste port 16 into the waste pipe 18 and finally into the waste bin 19. The defective product is collected by the waste bin 19, and the waste push rod 17 is reset to the initial position.

[0036] For reference Figure 3 , Figure 13 As shown, the worm gear assembly machine also includes a gripper A20, which is located above the transfer screening mechanism 6. The upper end of the gripper A20 is equipped with a cylinder G107, which is used to adjust the rotation of the gripper A20. The upper end of the cylinder G107 is equipped with a cylinder B102, which is used to adjust the lifting and lowering of the gripper A20. One end of the cylinder B102 is equipped with a cylinder H101, which is used to adjust the forward and backward movement of the gripper A20.

[0037] For reference Figure 3 , Figure 6 The worm gear assembly machine shown also includes a platform 21, on which there are storage slots A22 and B23. Storage slots A22 and B23 are used to place rod sleeves with different orientations. One end of the platform 21 is connected to a cylinder F106, which is used to adjust the left and right movement of the platform 21. One end of the cylinder F106 is connected to a cylinder E105, which is used to adjust the forward and backward movement of the platform 21.

[0038] In use, the platform 21 is moved to the front of the transfer screening mechanism 6 by cylinder E105. The gripper A20 is lowered by cylinder B102 to grab the rod sleeve located in the rod sleeve groove A10. After grabbing, the gripper returns to its original height and is then moved above the platform 21 by cylinder H101. It is lowered to place the rod sleeve in the placement slot A22. At this time, the platform 21 is moved to the left by cylinder F106, so that the placement slot B23 on the platform 21 is below the gripper A20. The gripper A20 then returns to its original position to grab the next rod sleeve. After grabbing the rod sleeve, the gripper A20 is rotated by cylinder G107 to adjust the orientation of the rod sleeve. After adjustment, the gripper A20 moves to place the adjusted rod sleeve in the placement slot B23. Both placement slots A22 and B23 are equipped with fiber optic sensors on one side. When both slots are filled with rod sleeves, the platform 21 returns to its original position above the tray.

[0039] like Figure 3 , Figure 6 , Figure 7-12 As shown, the worm gear assembly machine also includes a clamping assembly mechanism, which includes a lifting rod 24, a gripper B26, a transverse block 27, a driven slider 28, and a transverse block cylinder. The upper end of the lifting rod 24 is connected to the lifting rod cylinder, which is used to adjust the height of the lifting rod 24. The driven slider 28 is slidably disposed at both ends of the lifting rod 24, allowing for lateral position adjustment on the lifting rod 24. An adjustment port 25 is provided on the surface of the driven slider 28. The lowest point of the adjustment port 25 is near the inner side of the clamping assembly mechanism, while the highest point is near the outer side. A gripper B26 is movably disposed within the adjustment port 25, and the gripper B26 is rotatably connected to the transverse block 27. Therefore, when… When the upper end of the gripper B26 is at the highest point of the adjustment port 25, an outward force is applied to the upper end of the gripper B26. At this time, the lower ends of the two grippers B26 move in the same direction to achieve the gripping effect. When the upper end of the gripper B26 is at the lowest point of the adjustment port 25, it is equivalent to applying an inward force to the upper end of the gripper B26, thereby causing the two grippers B26 to move in opposite directions, thus achieving the opening effect of the gripper B26. There are two transverse blocks 27, and the transverse blocks 27 are installed at both ends of the transverse block cylinder. The transverse movement of the transverse block 27 is adjusted by the transverse block cylinder. When the transverse block 27 moves, it can move the driven slider 28 and the gripper B26 together.

[0040] In use, the clamping assembly mechanism uses cylinder D104 to descend and grip the two rod sleeves on the platform 21. Specifically, the lifting rod cylinder adjusts the lifting rod 24 to move downwards. At this time, the upper end of the gripper B26 moves to the highest point of the adjustment port 25. The upper end of the gripper B26 is constrained by the opening direction of the adjustment port 25, and the lower ends of the two grippers B26 move in the same direction. The rod sleeves are clamped between the gripper B26 and the transverse block 27, thus achieving the gripping of the two rod sleeves. After gripping, the platform 21 moves away from the tray and back to the front of the transfer screening mechanism 6. The clamping assembly mechanism then descends to obtain the worm gear and places the rod sleeves on both ends of the worm gear. Specifically, the transverse block cylinder adjusts the two transverse blocks 27 to move in opposite directions to increase the distance between the two transverse blocks 27. When the transverse blocks 27 move, the driven slider 28 moves along with them. Simultaneously, the gripper B26... The 6 also moves, increasing the distance between the grippers B26. After adjustment, the clamping assembly mechanism descends to the position of the worm. At this time, the two transverse blocks 27 move in the same direction, and the grippers B26 move accordingly to shorten the distance between the two grippers B26, thereby achieving a clamping effect on the worm. After clamping, both ends of the worm are respectively in the sleeve openings of the two sleeves. After the clamping assembly mechanism rises, it moves to the top of the worm assembly slot via cylinder C103. After the clamping assembly mechanism descends, it raises the height of the lifting rod 24 so that the upper end of the gripper B26 is at the lowest point of the adjustment port 25. Constrained by the opening direction of the adjustment port 25, the lower ends of the two grippers B26 move in opposite directions to release the clamping and fixing effect of the grippers B26 on the sleeves. At this time, the worm with the sleeves is placed in the worm assembly slot, thus completing the installation and position transfer of the worm assembly.
