Abstract
Description
Technical Field
[0001] This utility model relates to the field of loading and unloading technology, specifically to a gear processing loading and unloading device. Background Technology
[0002] In gear machining, workpieces need to be loaded and unloaded on gear machining equipment. Traditionally, this is done manually. Because manual loading and unloading is labor-intensive and costly, robotic arms have gradually been adopted. However, currently, when using robotic arms for loading and unloading, a batch of workpieces is typically placed on a positioning table beforehand by a human. The robotic arm then picks up each workpiece and installs it onto the equipment. After processing, the workpieces are unloaded from the equipment and placed back on the positioning table. Once all workpieces in a batch are processed, a worker transfers the materials and prepares for the next batch. This loading and unloading method cannot meet the demands of automated production.

[0037] Please refer to Figures 1 to 8 This application provides a gear processing loading and unloading device, including a frame 1 and a material frame translation mechanism. The frame 1 has a feeding bin 11 and a discharging bin 12 arranged side by side. The feeding bin 11 and the discharging bin 12 are respectively provided with material frame lifting brackets 2. The material frame lifting brackets 2 are used to support multiple stacked workpiece material frames 7. The two material frame lifting brackets 2 are respectively provided with lifting mechanisms between them and the frame 1. The lifting mechanisms are used to vertically lift and lower the material frame lifting brackets 2. The material frame translation mechanism is located at the top of the frame 1. The material frame translation mechanism is used to translate the uppermost workpiece material frame 7 from the feeding bin 11 to the discharging bin 12.
[0038] In use, multiple workpiece frames 7 containing gears 8 can be fed into the feeding bin 11 via a movable base. The stacked workpiece frames 7 are then lifted to a certain height by the lifting mechanism and the frame lifting bracket 2 of the feeding bin 11. The robotic arm of the processing equipment picks up and processes each workpiece frame one by one, and after processing, the workpieces are unloaded and placed back into the original workpiece frames 7. After the gears 8 in the top workpiece frame 7 are processed, the top workpiece frame 7 is moved from the top of the feeding bin 11 to the top of the discharge bin 12 by the frame translation mechanism. Then, the lifting mechanism and the frame lifting bracket 2 of the discharge bin 12 support the moved workpiece frames 7. The above actions are repeated until all workpiece frames 7 in the feeding bin 11 are transferred into the discharge bin 12, and then the entire assembly slides away from the discharge bin 12. This device requires minimal human intervention, meets the needs of automated production, and helps reduce production costs.
[0039] It should be noted that the mobile base is a device with wheels, which can be an automatic flatbed cart or a manual flatbed cart. Multiple workpiece frames 7 are stacked on the flatbed cart. After the flatbed cart enters the feeding hopper 11, the flatbed cart is just above the material frame lifting bracket 2. Then, by the action of the lifting mechanism, the material frame lifting bracket 2, the flatbed cart and multiple workpiece frames 7 can be lifted vertically as a whole.
[0040] According to some embodiments of this application, the lifting mechanism includes a lifting guide rail 31, a lifting rack 32, and a lifting servo motor 33. The lifting guide rail 31 and the lifting rack 32 are vertically arranged on the frame 1. The material frame lifting bracket 2 is slidably connected to the lifting guide rail 31. The lifting servo motor 33 is arranged on the material frame lifting bracket 2. A lifting gear is arranged on the output shaft of the lifting servo motor 33. The lifting gear meshes with the lifting rack 32.
[0041] In this embodiment, two lifting guide rails 31 are arranged vertically side by side on the frame 1, and a lifting rack 32 is located between the two lifting guide rails 31. A lifting servo motor 33 is installed on the lower side of the material frame lifting bracket 2. During operation, the lifting servo motor 33 drives the lifting gear to rotate, and the lifting gear meshes with the lifting rack 32, thereby driving the material frame lifting bracket 2 to slide along the lifting guide rails 31, thus realizing the height lifting movement of the workpiece material frame 7.
[0042] According to some embodiments of this application, a plurality of correction cylinders 6 are provided at the bottom of the frame 1. The correction cylinders 6 are respectively arranged on both sides of the feeding bin 11 and the discharging bin 12 to correct the position of the plurality of workpiece frames 7 stacked on the material frame lifting bracket 2. Since the position of the flatbed cart relative to the material frame lifting bracket 2 may not be accurate when the flatbed cart enters the feeding bin 11 and the discharging bin 12, two correction cylinders 6 are arranged opposite each bin. After the flatbed cart enters the bin and is lifted off the ground, the position of the flatbed cart on the material frame lifting bracket 2 can be adjusted by the pushing action of the two correction cylinders 6, thereby realizing the position correction of the plurality of workpiece frames 7 stacked on the material frame lifting bracket 2 to place them in a predetermined position.
[0043] According to some embodiments of this application, the frame 1 includes a vertical plate and three side plates arranged side by side on one side of the vertical plate, with the feed bin 11 and the discharge bin 12 formed between two adjacent side plates respectively.
[0044] According to some embodiments of this application, the material frame translation mechanism includes a translation guide rail 41, a material frame translation bracket 42, and a translation servo motor 43. The translation guide rail 41 is provided with a translation bracket slide 411 and a clamping unit slide 412. There are two translation bracket slides 411, which are respectively located on both sides of the clamping unit slide 412. There are two material frame translation brackets 42, which are correspondingly connected to the two translation bracket slides 411. The clamping unit slide 412 is provided with a pneumatic clamping unit 44 to clamp the uppermost workpiece material frame 7. The translation servo motor 43 drives the translation bracket slide 411 and the clamping unit slide 412 to slide along the translation guide rail 41 through a synchronous belt 46 wheel mechanism.
[0045] During operation, the two material frame translation brackets 42 are located on both sides of the uppermost workpiece material frame 7, and are clamped by the pneumatic clamping unit 44 to prevent the workpiece material frame 7 from shaking when the robot arm picks up or puts down the workpiece. After the workpiece in the uppermost workpiece material frame 7 is processed, the lifting mechanism of the feeding bin 11 moves the material frame lifting bracket 2 down to a certain height, thereby separating the remaining workpiece material frames 7 from the uppermost workpiece material frame 7. Then, the translation servo motor 43 drives the two material frame translation brackets 42 to move, thereby moving the uppermost workpiece material frame 7 from the top of the feeding bin 11 to the top of the discharging bin 12.
[0046] According to some embodiments of this application, the pneumatic clamping unit 44 includes a first clamping cylinder 441 and a second clamping cylinder 442. There are two first clamping cylinders 441 arranged back-to-back along the translation guide rail 41. The second clamping cylinder 442 is located between the two first clamping cylinders 441, and its clamping direction is perpendicular to the translation guide rail 41. After the piston rod of the first clamping cylinder 441 extends, it contacts the workpiece frame 7, pressing it against the limiting block on the translation bracket slide 411. After the piston rod of the second clamping cylinder 442 extends, it contacts the workpiece frame 7, pressing it in a direction perpendicular to the translation guide rail 41, ensuring that the position of the workpiece frame 7 remains unchanged.
[0047] According to some embodiments of this application, a plurality of auxiliary support blocks 421 are provided on the lower side of the material frame translation bracket 42. By providing a plurality of auxiliary support blocks 421, the workpiece material frame 7 can be supported, preventing the workpiece material frame 7 from accidentally separating from the material frame translation bracket 42 and falling off.
[0048] According to some embodiments of this application, the synchronous belt 46 wheel mechanism includes synchronous pulleys 45 and synchronous belt 46. The synchronous belt 46 is arranged along the direction of the translation guide rail 41. Two synchronous pulleys 45 mesh with the synchronous belt 46. The translation servo motor 43 drives one of the synchronous pulleys 45 to rotate.
[0049] According to some embodiments of this application, the material frame translation mechanism further includes an auxiliary guide rail 47 arranged along the direction of the translation guide rail 41. Support slides 48 are provided on the auxiliary guide rail 47, and there are two support slides 48 that are correspondingly connected to two material frame translation brackets 42. Since the material frame translation bracket 42 in this example is a slat structure, with one end fixedly connected to the translation bracket slide 411 and the other end fixedly connected to the support slide 48, both ends of the material frame translation bracket 42 are slidably connected. This allows for better force distribution and avoids slippage, jamming, abnormal noise, or deformation during operation.
[0050] According to some embodiments of this application, a sampling channel is provided on one side of the frame 1. The sampling channel includes a sampling guide rail 51 and a sampling cylinder 52 arranged side by side on the base. A sampling slide 53 is provided on the sampling guide rail 51, and a workpiece positioning fixture 54 is provided on the sampling slide 53. The sampling cylinder 52 is used to drive the sampling slide 53 to slide along the sampling guide rail 51. When workpiece sampling is required, the robot arm places the gear 8 to be sampled on the workpiece positioning fixture 54, and drives the sampling slide 53 to slide along the sampling guide rail 51 through the sampling cylinder 52, thereby transporting the gear 8 to the sampling station.
[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
