[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This device prevents errors by using a combination of error-proof components, a small cylinder, and a gate to ensure the input shaft of the riveted bearing and locking ring is in good condition. Specifically, the riveted input shaft is inserted upside down into the detection kit, and then the detection slot, in conjunction with a proximity sensor, performs the detection, resulting in the worm gear end facing upwards, as shown in the attached diagram in the instruction manual. Figure Six and accompanying diagrams Figure Seven As shown, when the riveting and locking ring is in good condition, the inner taper of the detection groove matches the outer taper of the locking ring. At this time, the bearing end face of the input shaft is in contact with the detection end face of the proximity sensor. The green light representing the qualified condition illuminates. At this time, the telescopic end of the small cylinder retracts, causing the gate to open. The operator then places the input shaft into the sliding area between the two support rods. Conversely, when the riveting and locking ring is in bad condition, the outer side of the locking ring lacks a taper, preventing it from matching the inner side of the detection groove. Consequently, the bearing end face of the input shaft cannot contact the detection end face of the proximity sensor, and the red light representing the unqualified condition illuminates. Considering the safety risks associated with using a small cylinder to close the gate, this device incorporates a miniature safety light curtain between the two U-shaped seats. This light curtain protects the operator; when the operator's hand touches the light curtain, the extension end of the small cylinder will not be pushed out, thus preventing the gate from pressing down and causing injury to the operator's hand. This device can automatically unload and assemble qualified input shafts located on the frame support rods into the material box through assembly and placement components, reducing the workload of operators and improving production efficiency.

Detailed Implementation Example 1

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figures 1 to 17 This utility model provides a technical solution: an input shaft unloading device with error prevention tooling, including a frame and error prevention components. The frame consists of four support columns 1 and a support plate 2. The four support columns 1 are fixed to the support plate 2 by angle brackets and screws. The top of each of the four support columns 1 is provided with a cavity for the insertion of adjusting rods 3. The top of each of the multiple adjusting rods 3 is fixed with a lifting column 4. The four lifting columns 4 are fixed to each other by connecting rods 5 and screws. The middle of the connecting rods 5 on the front and rear sides is provided with insertion holes for the installation of support rods 6 at equal intervals. There is a sliding area between each two adjacent support rods 6 for the input shaft to slide. The tops of the four lifting columns 4 are all fixed to the bottom of the same top frame 7 with screws. An L-shaped seat 8 is fixed to the upper front side of the top frame 7 with an angle bracket and screws. The upper end of the L-shaped seat 8 is fixed to the housing of the small cylinder 10 with a U-shaped clamp and screws. The telescopic end of the small cylinder 10 passes through the L-shaped seat 8 and is fixed to the drive bar 12 with a limit bolt 11 and nut. A gate 13 is fixed to the lower end of the drive bar 12. One of the lifting columns 4 has an anti-misoperation component on its outer side, which includes an L-shaped support 14, a detection kit 15, a proximity sensor 17, a controller 18, a backup power supply box 19, and a dual-color warning light strip 9. The detection kit 15 is fixed to the upper surface of the horizontal end of the L-shaped support 14 with screws. A receiving groove for the input shaft bearing is opened in the middle of the detection kit 15. A receiving cavity for the input shaft body is opened in the middle of the receiving groove. A detection groove 16 is provided between the middle of the receiving groove and the top of the receiving cavity, which fits with the locking ring after the input shaft is riveted. The inner wall taper of the detection groove 16 is adapted to the taper of the locking ring after riveting. The bottom of the receiving groove has symmetrically opened cavities for the installation of the proximity sensors 17. The bottoms of the two proximity sensors 17 are connected to the controller 18 through wires. The front end of the controller 18 has a control panel. The controller 18 is also electrically connected to the backup power supply box 19 and the dual-color warning light strip 9 through wires. 9 is set at the upper end of the tray 2. The dual-color warning light strip 9 is fixed to the front side of another lifting column 4 by screws. Considering that after the input shaft is press-fitted with the bearing and locking ring, it is placed on the buffer rack, waiting to be boxed for use in the next process, the placement process requires the staff to check the pressing taper of the locking ring. Currently, the main method is to visually observe the pressing taper after locking and riveting, and manually rotate and turn the bearing to check whether it is pressed in place. The inspection efficiency is slow, and when the operator is visually fatigued, it is easy to cause the taper to be unqualified, and unfit parts that have not been riveted are placed in the buffer rack. This device plays a role in preventing errors by setting up an error-proof component, a small cylinder 10 and a gate 13 to cooperate with each other to ensure the qualified state of the input shaft with the riveted bearing and locking ring. That is, the input shaft after riveting is inverted and inserted into the inside of the detection kit 15, and then the detection groove 16 is used in conjunction with the proximity sensor 17 to detect it, resulting in the state with the worm end facing upward, as shown in the attached figure of the instruction manual. Figure Six and accompanying diagrams Figure Seven As shown, when the riveting and locking ring is in good condition, the inner taper of the detection groove 16 matches the outer taper of the locking ring. At this time, the bearing end face of the input shaft is in contact with the detection end face of the proximity sensor 17. At this time, the green light bar representing the qualified state of the dual-color warning light 9 lights up. At this time, the telescopic end of the small cylinder 10 retracts, driving the gate 13 to open. At this time, the operator places the input shaft into the sliding area between the two support rods 6. Conversely, when the riveting and locking ring is in bad condition, because the outer side of the locking ring has no taper, it cannot match the inner side of the detection groove 16. Therefore, the bearing end face of the input shaft cannot contact the detection end face of the proximity sensor 17. At this time, the red light bar representing the unqualified state of the dual-color warning light 9 lights up. A movable support 35 is fixed to the rear of the frame. An assembly component and a placement component are respectively provided on the upper end of the movable support 35. A housing for an air pump 56 is also provided on the upper end of the support plate 2. The negative pressure end of the air pump 56 extends to the outside of the housing through a pipe. The output end of the air pump 56 extends to the upper end of the housing through a connecting pipe and connects to a multi-port pipe 57. Multiple air outlets of the multi-port pipe 57 are connected to the air supply pipe 45 through control valves 58. Considering the inconvenience of manually removing and packing input shafts when the box is full, this device automatically unloads qualified input shafts located on the support rod 6 of the frame into the material box 52 using the assembly component and the placement component. This is achieved by vertically moving the drive end of the first motor slide rail 34. During movement, the support rod 36 completes the guiding process through the guide component. Subsequently, the drive end of the second motor slide rail 37 moves horizontally. When the second motor slide rail 37… When the drive end moves to the material-picking position above the support rod 6, the drive end of the first motor slide rail 34 descends vertically, causing the limiting sleeve 41 to be fitted onto the outside of the input shaft end. Then, the telescopic end of the thin-plate cylinder 42 pushes out to fix the input shaft end. At this time, the drive end of the first motor slide rail 34 moves upward to disengage the input shaft from the support rod 6. Then, the drive end of the second motor slide rail 37 moves horizontally to move the input shaft above the material box 52. At this time, after the positioning sensor 55 senses the alignment, the drive end of the first motor slide rail 34 moves longitudinally to insert the row of input shafts into the material box 52. Then, the telescopic end of the thin-plate cylinder 42 retracts to make the input shaft fall into the material box 52. At this time, the automatic unloading and assembly process is completed, thereby reducing the operator's workload. The operator only needs to replace the material box 52. When replacing, ensure that the holes on both sides of the material box 52 are aligned with the positioning pins 53.

[0024] One of the lifting columns 4 has a power button 20 fixed to its front side by screws. The power button 20 is connected to the backup power supply and the controller 18 by wires. The controller 18 is also electrically connected to the infrared counter 21 by wires. The infrared counter 21 is fixed to the outside of the vertical end of the L-shaped support 14 by screws. Considering that the assembly workers need to frequently check whether the buffer rack is full and need to unload materials, this device uses the infrared counter 21 to sense and detect the number of input shafts. After processing by the controller 18's built-in processing module, the number of input shafts is displayed on the control panel screen to facilitate workers to unload materials according to the quantity. It should be noted that the counter only records the number of input shafts in the qualified state, that is, input shafts in the unqualified state are not included in the counter's display.

[0025] The bottom of each of the four support pillars 1 is equipped with a self-locking caster wheel 22 by screws. A spring pin 26 is installed on the outer side of each of the four support pillars 1. The pin head of each spring pin 26 penetrates into the cavity and abuts against the adjustment hole 23. The adjustment holes 23 are evenly spaced on one side of each adjustment rod 3. A ball bearing 24 abuts against the other side of each adjustment rod 3. The ball bearing 24 is located on the inner wall of the cavity. A polyurethane block 25 is fixed to the bottom of each adjustment rod 3. Considering the different heights of each assembler, the comfortable operating height varies, meaning the optimal working height for placing the input shaft to the sliding area differs. Therefore, the operating height of the support rod 6 is designed to be adjustable. When adjustment is needed, pulling the spring pin 26 disengages the pin head from the adjustment hole 23, allowing the lifting column 4 to be raised. After the adjustment rod 3 is raised and lowered to the desired height, the spring pin 26 is released, and the pin head of the spring pin 26 abuts against the adjustment hole 23, fixing its position.

[0026] Each sliding area has a width greater than the diameter of the input shaft body but less than the diameter of the input shaft bearing. Each sliding area has a polyurethane buffer pad 27 at its tail end, which is bonded to the surface of one of the connecting rods 5. The polyurethane buffer pad 27 protects the collision surface between the sliding area and the connecting rod 5. When the input shaft is placed in the sliding area, it slides along the support rod 6. When it reaches the bottom, it will collide with the connecting rod 5. At this time, the polyurethane buffer pad 27 will cushion the impact, preventing the input shaft and bearing from contacting the surface of the connecting rod 5 and thus preventing damage.

[0027] Each support rod 6 has threaded grooves at both ends for the positioning bolts 28 to be screwed in, and both ends of the support rod 6 pass through the insertion holes and are fixed to the connecting rod 5 by the positioning bolts 28. The positioning bolts 28 fix the support rod 6 and the connecting rod 5, and the number of support rods 6 can be increased or decreased according to actual production needs.

[0028] The four lifting columns 4 form a square area. The square area is fixed to the protective plate 30 by mounting bolts 29 on both sides and the top of the top frame 7. The protective plate 30 is made of transparent material. The protective plate 30 protects the input shaft placed on the support rod 6, preventing items from falling and hitting the input shaft, which could cause the input shaft to fall and become damaged.

[0029] Among them, U-shaped seats 31 are fixed on the opposite sides of the two lifting columns 4 on the front side. A miniature safety light curtain 32 is fixed on one side of the middle of the two U-shaped seats 31 by a U-shaped hoop. A guide shaft 33 for guiding the side of the gate 13 is fixed on the other side of the middle of the two U-shaped seats 31. The outer surface of the guide shaft 33 is an arc-shaped concave surface. Considering the safety risk of the small cylinder 10 driving the gate 13 to close, a miniature safety light curtain 32 is set between the two U-shaped seats 31. The miniature safety light curtain 32 can be used to protect the operator. That is, when the operator's hand touches the light curtain formed by the miniature safety light curtain 32, the extension end of the small cylinder 10 will not be pushed out, avoiding the situation where the gate 13 is pressed down and the operator's hand is injured.

[0030] The assembly includes a first motor slide rail 34, a second motor slide rail 37, a connecting seat 38, a limiting sleeve 41, and guide members. The bottom of the first motor slide rail 34 is fixed to the moving support 35 by angle brackets. The sliding end of the first motor slide rail 34 is fixed to the second motor slide rail 37 by a support rod 36. The side of the first motor slide rail 34 has a guide groove for longitudinal movement of the sliding end. The lower end of the second motor slide rail 37 has a guide groove for horizontal movement of the driving end. A connecting seat 38 is fixed to the bottom of the driving end. The bottom of the connecting seat 38 has a slot for the positioning strip 39 to be inserted. The positioning strip 39 and the slot are limited by a fixing bolt 40. The lower end of the positioning strip 39 is fixed with multiple members at equal intervals for... A limiting sleeve 41 is fitted onto the end of the input shaft. A thin-plate cylinder 42 is provided on one side of each limiting sleeve 41. The telescopic end of the thin-plate cylinder 42 passes through the interior of the limiting sleeve 41 and is fixed to the arc-shaped positioning plate 43. A gasket 44 for abutting against the side wall of the input shaft is also fixed inside the limiting sleeve 41. The air inlet end of the thin-plate cylinder 42 is connected to the air supply pipe 45. The top of the guide passes through the drive end of the first motor slide rail 34 and extends into the interior of the support rod 36. Considering that it is inconvenient for the assembly personnel to pick up and put down the input shaft located on the upper end of the support rod 6 into the material box 52, an assembly assembly is designed. The assembly assembly is used to pick up and put down the input shaft located on the support rod 6 into the material box 52, thereby reducing the workload of the assembly personnel.

[0031] The placement assembly includes a base 46, a load-bearing tray, a material box 52, and a damping rod 49. The upper center of the base 46 has an insertion hole for a connecting post 47. A return spring 48 abuts against the insertion hole and the connecting post 47. The upper end of the base 46 also has a countersunk hole for mounting the damping rod 49 and a guide post 50. The load-bearing end of the damping rod 49 is fixed to the bottom of the load-bearing tray, and the top of the guide post 50 is fixed to the bottom of the load-bearing tray. A polyurethane ring 51 is fixedly fitted onto the outside of the guide post 50. The upper end of the load-bearing tray is fixed with four locating pins 53 in a rectangular shape for docking with the material box 52. The upper end of the material box 52 is provided with material holes at equal intervals for placing multiple input shafts. Considering that the input shaft will generate a certain impact force after being placed in the material box 52, a return spring 48 and a damping rod 49 are designed so that the impact force generated by placing the input shaft can be absorbed by the return spring 48. When the return spring 48 absorbs the impact force and releases elastic potential energy, it will be weakened by the damping rod 49, thereby completing the buffering process.

[0032] In this design, an L-shaped block 54 is fixed to one side of both the connecting seat 38 and the load-bearing tray. A positioning sensor 55 is fixed to the opposite face of each of the two L-shaped blocks 54. By setting the positioning sensor 55, the input shaft can be accurately positioned when the second motor slide rail 37 drives the input shaft to the material box 52 placement position, thereby placing the input shaft into the material box 52. Since the material holes on the material box 52 are equally spaced, after the first row of input shafts in the material box 52 is placed, the placement of the other rows of input shafts can be achieved by the motor driver inside the second motor slide rail 37 in conjunction with the controller 18 programmed movement drive, i.e., the number of rotations of the motor, thereby completing the process of inserting the input shaft into the material box 52. Example 2

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Please see Figure 13 This utility model provides a technical solution: an input shaft unloading device with error-proof tooling. The external shape of the detection kit 15 can also be designed as a U-shaped structure. Considering that the ring-shaped detection kit 15 has low placement efficiency when in use, that is, it is not convenient to place the input shaft by holding the worm end. Therefore, it is designed as a U-shaped structure with an opening. At this time, when the assembly personnel place the input shaft, they can place it directly through the notch, which improves the convenience and makes it easier to place and remove.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
