Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , a detection device for a metal pipe fitting in this embodiment includes a detection table. A conveying table 1 is installed on the detection table, a transfer table 6 docked with the tail end of the conveying table 1, a lifting assembly 3 installed on the detection table at the bottom of the conveying table 1 and capable of extending to the top to lift the pipe fitting, and a visual detection device 2 installed opposite to the lifting assembly 3. At the same time, a vertical conveying table 501 docked with the tail end of the transfer table 6 is installed on the detection table, and a linear module 4 is installed on the detection table. A transfer assembly 7 that can reciprocate between the tail end of the conveying table 1 and the head end of the transfer table 6 is fixed to the moving end of the linear module 4. A plurality of support blocks 502 are installed on the conveyor belt of the vertical conveying table 501. Two semi-circular concave surfaces are formed on the top of the support blocks 502. A material distribution assembly 5 is installed on both the vertical conveying table 501 and the transfer table 6.

[0019] In the above structure, the pipe fittings are successively conveyed above the lifting assembly through the conveying table. The lifting assembly can lift a certain number of pipe fittings, and at the same time, the visual detection device is used to detect between the pipe orifices, so as to realize automatic detection and batch detection to improve efficiency. Then, the linear module drives the transfer assembly to complete the transfer of the detected pipe fittings to the transfer table. Then, in cooperation with the material distribution assembly, the pipe fittings can be pushed onto the support blocks. The vertical conveying table conveys the products to the middle section and the top section. The middle section is the unqualified product area, and the top section is the qualified product area. Then, in cooperation with the material distribution assembly, the pipe fittings can be pushed to complete the sorting.

[0020] As Figure 2 shown in the direction, the lifting assembly 3 includes a mounting seat 301 fixed on the detection table. A lifting cylinder 302 is installed on the inner top wall of the mounting seat 301, and two guide rods 304 are slidably connected. The ejecting end of the lifting cylinder 302 is fixed with a U-shaped plate 303 connected to the two guide rods 304. Five corresponding semi-circular grooves are formed on the two top surfaces of the U-shaped plate 303. Inductive sensors are installed at the middle section and the tail section of the conveying table 1 corresponding to the U-shaped plate 303. When the conveying table conveys the pipe fittings above the lifting assembly, through the induction of the inductive sensor, the lifting cylinder drives the U-shaped plate to lift, so that a certain number of pipe fittings can be lifted to a certain height to be flush with the visual detection device to complete the detection, thereby realizing batch detection and improving efficiency.

[0021] Among them, side push cylinders 305 are installed on both the left and right sides of the mounting base 301. Two baffles 306 are fixed to the ejecting end of the left side push cylinder 305, and two support plates 307 are fixed to the ejecting end of the right side push cylinder 305. The top ends of the support plates 307 are also provided with semi-circular grooves identical to those of the U-shaped plate 303. The baffle 306 is attached to the left side of the U-shaped plate 303, and the support plate 307 is attached to the right side of the U-shaped plate 303. When the pipe fittings move on the conveying table, first, the side push cylinder jacks up the baffle to block the pipe fittings. Until a certain number is reached, the side push cylinder then jacks up the support plate, which can disconnect and distinguish the pre-waiting area for the conveyed pipe fittings, and limit the conveyed pipe fittings. When a certain number of pipe fittings are located between the support plate and the baffle, then the lifting cylinder drives the U-shaped plate to jack up, which can accurately and smoothly jack up the same number of pipe fittings for inspection.

[0022] As Figure 5 For the direction shown, the transplanting assembly 7 includes a moving plate 701 fixed to the moving end of the linear module 4. A lower jacking cylinder 702 is installed on the top of the moving plate 701, and sliding rods 703 are arranged on both sides of the lower jacking cylinder 702. A rotary cylinder 704 connected to the sliding rods 703 is installed at the ejecting end of the lower jacking cylinder 702. A rotating seat 705 is fixed to the rotating end of the rotary cylinder 704. An adsorption block 706 is installed at the bottom of the rotating seat 705. The bottom of the adsorption block 706 also forms semi-circular grooves with the same number as that of the U-shaped plate 303. Through the linear module, the adsorption block can be driven by the moving plate to move on the transfer table and the conveying table. By operating the lower jacking cylinder, the adsorption block can be attached to and adsorbed by the pipe fittings. When it is necessary to transfer to other places and the directions are different, the direction of the adsorption block can be adjusted by the rotary cylinder.

[0023] As Figures 3-4 , the material distribution assembly 5 includes two pushing cylinders 503 installed on the left side of the tail section of the transfer table 6, the right side of the middle section of the vertical conveying table 501, and the left side of the top section. Transmission plates 504 opposite to the pushing cylinders 503 are fixed on both sides of the vertical conveying table 501. On the side of the top transmission plate 504 opposite to the support block 502, and on the right side of the tail section of the transfer table 6, communication plates 505 opposite to the corresponding pushing cylinders 503 are fixed. Inductive sensors are installed at the tail section of the transfer table 6, the middle section, and the top section of the vertical conveying table 501. The ejecting end of the pushing cylinder 503 is equal to the diameter of the semi-circular groove. The transfer table conveys the products to the tail section. Through the cooperation of the inductive sensor and the vertical conveying table, the pushing cylinder operates, and the pipe fittings can be pushed onto the support block under the connection of the communication plate, and then conveyed to the middle section and the top section through the vertical conveying table. Through the induction of the inductive sensors in the middle section and the top section, the unqualified products are pushed out by the pushing cylinder in the middle section in cooperation with the transmission plate. When the vertical conveying table conveys the pipe fittings to the top section, the qualified products can be pushed out by the pushing cylinder in cooperation with the communication plate and the transmission plate, so as to realize the classification and sorting of the pipe fittings.

[0024] The working principle of the above embodiments is as follows:

[0025] The pipe fittings are conveyed by the conveying table. First, the side-pushing cylinder drives the baffle to lift up, which can block and limit the pipe fittings. When a certain quantity is reached, the side-pushing cylinder drives the supporting plate to lift up, lifting a group of pipe fittings to cut off the conveying area and divide it into a waiting area. Then, the lifting cylinder drives the U-shaped plate to lift the product to face the vision inspection device, so that the products can be inspected in batches. The baffle and the U-shaped plate retract. The inspected pipe fittings will be conveyed to the tail section of the conveying table. Then, the linear module drives the adsorption block to move. At the same time, the lower-lifting cylinder drives the adsorption block and the pipe fitting to stick together through the rotary cylinder and the rotating seat and adsorbs and transfers them to the transfer table until it is conveyed to the tail section. The two pipe fittings are butted and pushed to the supporting block through the connecting plate by the pushing cylinder. The vertical conveying table transfers the pipe fittings to the middle section through the supporting block. The unqualified products are pushed out by the pushing cylinder in cooperation with the transmission plate, and then continuously sent up to the top. The qualified products are pushed out by the pushing cylinder through the connecting plate and the transmission plate.

[0026] In summary, it can achieve automatic batch detection, improve the detection efficiency and reduce the detection cost. At the same time, it can also automatically convey and sort qualified and unqualified products.
