Description

Technical Field

[0001] This utility model relates to the technical field of parts processing production lines, specifically to a small and medium-sized parts receiving device. Background Technology

[0002] Traditional assembly line operations mainly rely on manual visual inspection of the appearance of parts to distinguish between good and defective products. Good products flow to the next station, while defective products are returned for rework. Therefore, the assembly line is equipped with a good product area and a defective product retention area.

[0003] With the continuous advancement of technology, automated mechanisms such as automatic identification and automatic rejection of defective products have gradually matured. Specifically, they rely on vision modules to locate and identify defective products, and use cylinders to remove marked defective products, thereby achieving product differentiation and area management.

[0004] For parts with surface coating, surface damage often occurs during use due to friction or collision between the parts and the receiving tray. The conventional approach is to attach cushioning materials such as foam to the inside of the receiving tray, but the foam suffers from aging, breakage, and detachment. Therefore, a new type of receiving equipment needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a small and medium-sized parts receiving device that uses a variable frequency motor as a power source and drives the turntable to rotate through a reducer, slewing support and other transmission devices to achieve automatic separation of good and defective small and medium-sized parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small and medium-sized parts receiving device, including a device frame, a drive mechanism, a transmission mechanism, and a parts sorting mechanism;

An arc-shaped baffle is provided on the side of the good parts inlet away from the partition plate. The arc-shaped baffle and the partition plate form a good parts entry channel. The arc-shaped baffle is used to guide the parts from the good parts inlet to the center of the turntable.

[0010] Furthermore, a crossbeam is provided at the top of the annular baffle, and the upper end face of the partition plate is fixedly connected to the lower end face of the crossbeam.

[0011] Furthermore, a support frame is provided between the turntable and the inner ring. The lower end of the support frame is fixedly connected to the inner ring by vertically arranged screws. Multiple adjustment blocks are provided at the lower end of the turntable. The adjustment blocks have screw holes corresponding to the positions of the support frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 This utility model provides a small and medium-sized parts receiving device, including a device frame 10, a drive mechanism, a transmission mechanism, and a parts sorting mechanism.

[0026] The assembly plate 11 is fixedly connected to the equipment frame 10.

[0027] The drive mechanism includes a variable frequency motor 21 and a reducer 22 that is connected to the output shaft of the variable frequency motor 21. Both the variable frequency motor 21 and the reducer 22 are fixed to the lower surface of the mounting plate 11 by screws. The mounting plate 11 is provided with a through hole that matches the output shaft of the reducer 22.

[0028] The transmission mechanism includes a slewing bearing and a gear 31. The slewing bearing includes an outer ring 32 and an inner ring 33 that are rotatably connected. The outer ring 32 and the inner ring 33 are rotatably connected by a combination of bearings or guide rails and grooves. The outer ring 32 is fixedly connected to the upper surface of the mounting plate 11 by screws. A gear ring 34 is fixedly connected to the inner wall of the inner ring 33. The gear 31 is coaxially fixed to the output shaft end of the reducer 22. The gear 31 meshes with the gear ring 34 for transmission.

[0029] The parts sorting mechanism includes a turntable 41 and an annular baffle 42 surrounding the turntable 41. The turntable 41 is fixedly connected to the inner ring 33. Specifically, a support frame 43 is provided between the turntable 41 and the inner ring 33. The lower end of the support frame 43 is fixedly connected to the inner ring 33 by vertically arranged screws. Multiple adjusting blocks 44 are provided at the lower end of the turntable 41. The adjusting blocks 44 and the support frame 43 are provided with corresponding screw holes. The position of the turntable 41 is adjusted by adjusting the distance between the adjusting blocks 44 and the support frame 43 by horizontally arranged screws 45.

[0030] An annular baffle 42 is fixedly connected to the equipment frame 10. A part inlet is provided on the annular baffle 42. A partition plate 46 is provided inside the annular baffle 42, dividing it into a good product temporary storage area A and a defective product temporary storage area B. One end of the partition plate 46 is located at the part inlet, dividing it into a good product inlet C and a defective product inlet D. An arc-shaped baffle 47 is provided on the side of the good product inlet C away from the partition plate 46. The arc-shaped baffle 47 and the partition plate 46 form a good product entry channel. The arc-shaped baffle 47 guides the parts from the good product inlet C to the center of the turntable 41. A crossbeam 48 is provided at the top of the annular baffle 42, and the upper end face of the partition plate 46 is fixedly connected to the lower end face of the crossbeam 48.

[0031] Let's take the material receiving scenario as an example to illustrate its working principle:

[0032] Please see Figure 4 In actual use, a parts conveyor line 51 is set on the outside of the equipment frame 10. The parts conveyor line 51 is located on one side of the parts inlet. A vision inspection module 52 and a pusher cylinder 53 are set on one side of the parts conveyor line 51. When the vision inspection module 52 detects a defective product, the vision inspection module 52 transmits the information of the part to the central control system. The control system controls the pusher cylinder 53 to push the defective product to the outside of the parts conveyor line 51. Good parts enter the good product temporary storage area A through the good product inlet C, and defective parts enter the defective product temporary storage area B through the defective product inlet D.

[0033] The turntable 41 is set to rotate counterclockwise. Qualified parts conveyed by the conveyor belt enter the turntable 41 through the good product inlet C. Guided by the arc-shaped baffle 47 and the partition plate 46, they move with the turntable 41 into its interior and gradually converge. The arc-shaped baffle 47 primarily keeps the parts a certain distance away from the fixed annular baffle 42, preventing continuous wear on the precision parts due to friction between the parts and the annular baffle 42. The partition plate 46 primarily guides and concentrates the materials, isolating them from materials of different states entering through the defective product inlet D. If it is not necessary to distinguish between materials of different states, the partition plate 46 and the pusher cylinder 53 can be omitted.

[0034] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
