Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel testing equipment, specifically to a feeding device for grinding wheel testing. Background Technology

[0002] In existing grinding wheel inspection operations, traditional feeding methods are mainly divided into two categories: manual assisted feeding and simple mechanical feeding. Among them, the manual assisted feeding method relies on operators to pick up the grinding wheels one by one and place them on the inspection conveyor line. This method is not only labor-intensive and costly, but also susceptible to human factors such as operator fatigue and differences in operating skills, making it difficult to ensure the consistency of the feeding rhythm. It is prone to problems such as feeding interruption or delay, causing subsequent inspection equipment to frequently be in standby mode, which seriously restricts the improvement of overall inspection efficiency and cannot meet the batch inspection needs of large-scale grinding wheel production.

[0003] To address the shortcomings of manual feeding, simplified mechanical feeding devices have gradually emerged in the industry. These devices typically employ a single conveying mechanism to transfer grinding wheels, such as directly grabbing the wheels via a conveyor belt or robotic arm. However, existing simplified mechanical feeding devices generally suffer from two major problems: First, their material storage capacity is limited; most devices can only accommodate a small number of grinding wheels to be tested, requiring frequent replenishment by operators. Interruptions in feeding during replenishment are still unavoidable, resulting in insufficient continuous feeding capacity. Second, their feeding structure design is simplistic, lacking an efficient coordination mechanism with the storage mechanism. This leads to problems such as jamming and stacking during grinding wheel transfer, further affecting the stability and continuity of feeding. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a feeding device for grinding wheel testing. The feeding module enables continuous feeding and increases the material storage capacity. The combination of these two modules enables continuous conveying of the grinding wheel to be tested, greatly improving feeding efficiency and thus enhancing overall operational efficiency.

[0005] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a feeding device for grinding wheel inspection, comprising a frame, a conveyor belt disposed in the middle of the frame, a feeding assembly disposed at the end of the conveyor belt, the feeding assembly comprising a gripping module and a feeding module, the gripping module comprising a transfer disc, a rotary drive source disposed in the middle of the transfer disc, a gripping suction cup disposed on the transfer disc, the feeding module comprising a feeding disc, a rotating bracket disposed in the middle of the feeding disc, a storage plate disposed on the feeding disc, a lifting mechanism cooperating with the storage plate disposed on one side of the feeding disc, and a height detection module disposed above the feeding disc.

[0006] As a further improvement to the above technical solution: A ring-shaped guide rail is provided above the transfer tray, and a lifting mechanism that works in conjunction with the ring-shaped guide rail is provided on the upper part of the gripping suction cup.

[0007] The lifting mechanism includes a guide rod, with a roller on the upper part of the guide rod, and a groove on the annular guide rail for use with the roller.

[0008] The number of gripping suction cups is multiple and they are evenly distributed along the circumference of the transfer disk.

[0009] The lifting mechanism includes a lifting belt, a fixed seat on the lifting belt, and a fork plate on the fixed seat for lifting the storage plate.

[0010] The number of storage plates is multiple and they are evenly distributed along the circumference of the feeding tray. An extension plate for mounting the feeding tray is provided on the outer wall of the feeding tray.

[0011] The extension plate is provided with guide columns, and the storage plate has through holes in the middle corresponding to the positions of the guide columns.

[0012] A clearance groove is provided in the middle of the fork plate, and the width of the extension plate is smaller than the width of the clearance groove.

[0013] The height detection module uses an infrared sensor and is coaxially distributed with the fork plate.

[0014] The number of feeding assemblies is two, and they are located on opposite sides of the conveyor belt.

[0015] The beneficial effects of this utility model embodiment are as follows: The feeding device for grinding wheel testing includes a frame, a conveyor belt in the middle of the frame, and a feeding assembly at the end of the conveyor belt. The feeding assembly includes a gripping module and a feeding module. The gripping module can quickly place materials on the conveyor belt and then transport them to the testing equipment for testing. The feeding module includes multiple storage plates, each of which can hold multiple materials to be tested. The materials to be tested are then transported to the area below the gripping suction cup by a lifting mechanism for easy transfer by the gripping module. The combination of the two significantly improves the material conveying efficiency. Moreover, the feeding module can replenish materials by rotating the storage plates without stopping the machine, which greatly improves the continuity of the operation. Attached Figure Description

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-6 As shown, the feeding device for grinding wheel inspection in this embodiment includes a frame 1, with a conveyor belt 2 located in the middle of the frame 1 as the main channel for grinding wheel transfer. Two sets of feeding components (located on both sides of the conveyor belt 2) are symmetrically arranged at the ends of the conveyor belt 2 for efficient feeding. Each feeding component includes a gripping module and a feeding module, which work together to complete the entire process of grinding wheel transfer from storage to transportation.

[0020] The gripping module includes a transfer disk 3, with a rotary drive source 4 mounted in the center to drive its rotation. Multiple gripping suction cups 5 are evenly distributed along the circumference of the disk to ensure continuous and stable material feeding. To precisely control the movement trajectory of the gripping suction cups 5, a ring-shaped guide rail 10 is installed above the transfer disk 3, and a lifting mechanism that works in conjunction with the ring-shaped guide rail 10 is mounted on the upper part of each gripping suction cup 5.

[0021] The lifting mechanism specifically includes a guide rod 11, with a roller 12 mounted on the upper part of the guide rod 11. Correspondingly, a groove 13 adapted to the roller 12 is machined on the annular guide rail 10. The roller 12 rolls in the groove 13. The groove 13, the height detection module 9, and the fork plate 16 are all coaxially distributed. When the corresponding gripping suction cup 5 moves to the groove 13, the guide rod 11 sinks, causing the gripping suction cup 5 to descend and contact the grinding wheel to be gripped, thus completing the gripping operation. The design of the groove 13 can smoothly drive the gripping suction cup to descend at the gripping position, and then lift it up after gripping. The height lifting can avoid the gripping suction cup 5 from colliding with the grinding wheel during rotation, and can also ensure that the gripping operation is completed smoothly, avoiding idle rotation.

[0022] The feeding module includes a feeding tray 6, which rotates flexibly in the middle via a rotating bracket 7. Multiple storage plates 8 are evenly distributed along the circumference of the tray, each capable of holding multiple stacked grinding wheels to be tested. A lifting mechanism is located on one side of the feeding tray 6, working in conjunction with the storage plates 8. A height detection module 9, using an infrared sensor, is mounted above the feeding tray 6 to detect the height of the storage plates 8. This module is coaxially aligned with the fork plate 16 of the lifting mechanism to ensure detection accuracy. The height of the height detection module 9 and the grinding wheels to be tested is set to A. When the previous grinding wheel to be tested is gripped, A increases. After the height detection module 9 sends a feedback signal, the lifting mechanism electrically moves the storage plate 8 upward, transporting the next grinding wheel to be tested to the gripping position.

[0023] The lifting mechanism includes a lifting belt 14, a fixed seat 15, and a fork plate 16 for lifting the storage plate 8. To prevent interference between the fork plate 16 and the installation structure of the feeding tray 6, a clearance groove 20 is provided in the middle of the fork plate 16, and the width of the extension plate 17 for installing the feeding tray 6 on the outer side wall of the feeding tray 6 is smaller than the width of the clearance groove 20.

[0024] Meanwhile, the extension plate 17 is also equipped with a vertically installed guide column 18, and the middle part of the storage plate 8 is machined with a through hole 19 corresponding to the position of the guide column 18. Through the cooperation of the guide column 18 and the through hole 19, the storage plate 8 is kept stable during the lifting process to avoid the grinding wheel from shifting or tipping over.
