Description

Technical Field

[0001] This utility model belongs to the field of massager technology, and specifically relates to a flipping feeding mechanism for identifying and detecting the direction of materials. Background Technology

[0002] During the assembly of zipper pulls, damaged or defective pull tabs are often mixed in with intact ones. During production and transport, small quantities of pull tabs of different models and brands may also be mixed in. Therefore, pull tabs of different models or brands need to be manually removed during transport, or those with different orientations or front-to-back orientations need to be adjusted. However, this method suffers from low automation, low assembly efficiency, and high labor intensity for employees. Furthermore, manual selection is prone to visual fatigue and lacks accuracy. Later, a method using camera recognition systems to intelligently detect defective products emerged on the market.

[0003] For example, Chinese invention patent CN102495076B, entitled "A Method for Detecting Defects in Zipper Metal Teeth Based on Machine Vision," discloses a method for detecting defects in zipper metal teeth based on machine vision. This method utilizes a detection device consisting of a feeding mechanism, a material position sensor, an image sensor, a stepper motor / servo motor, a light box, a conveyor belt, a sorting mechanism, a stainless steel slide rail, a controller, and a control system. The zipper to be inspected is fed to the conveyor belt platform of the detection device by the feeding mechanism, located by the material position sensor, and the image sensor is activated to acquire an image of the zipper. The image is then transmitted to the control system, which processes the image and compares the processing result with a discrimination standard to determine whether the zipper has a defect. This invention enables simultaneous detection of metal tooth defects, overcoming the limitation of existing technologies that can only detect a specific defect, thus improving detection efficiency.

[0004] Although the aforementioned patent can achieve automated inspection through machine vision, it can only send zippers with discrepancies to the defective product area and send qualified products to the next packaging production process based on the results of machine vision inspection. It cannot automatically adjust products with different orientations or different front and back sides, and the degree of automation is not high.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0025] like Figures 1 to 5 As shown, a flipping feeding mechanism for identifying and detecting the direction of materials includes a first feeding trough 1, a conveyor belt 2 located at the outlet of the first feeding trough 1, a controller 10 for controlling the stroke of the conveyor belt 2, a second feeding trough 3 located at the outlet of the conveyor belt 2, and a flipping assembly 4 located at the outlet of the second feeding trough 3. Specifically, both the first feeding trough 1 and the second feeding trough 3 are arranged at an angle. Figure 3As shown, the conveyor belt 2 in this utility model has the structure of a conventional conveyor belt 2, that is, the conveyor belt 2 includes two driven wheels 21 and a belt body 22 wound around the driven wheels 21. Correspondingly, it also includes a frame 100. The two driven wheels 21 are both set on the frame 100 and are respectively located at both ends of the conveying direction of the frame 100. The frame 100 is provided with a drive motor 23 for driving the driven wheels 21 to rotate. The controller 10 is fixed on the frame 100. Preferably, in this utility model, the controller 10 adopts a conventional cam divider in the art. The output end of the drive motor 23 is connected to the cam divider. The conveyor belt 2 also includes two rotating wheels 24 rotatably set near the cam divider. The belt body 22 is attached to the cam divider through the two rotating wheels 24 rotatably set on the frame 100, so that the cam divider can control the stroke of the conveyor belt 2.

[0026] The conveyor belt 2 is provided with a first blocking component 5 for blocking the material on the conveyor belt 2, a vision detection module 6 for detecting the material on the conveyor belt 2, a pushing component 7 for pushing the material on the conveyor belt 2 out, and a rotating component 8 for rotating the material on the conveyor belt 2 horizontally. The first blocking component 5, the vision detection module 6 and the rotating component 8 are arranged sequentially along the conveying direction of the conveyor belt 2. The vision detection module 6 is fixed on the frame 100 by a bracket. like Figure 1 and Figure 5 As shown, the rotating assembly 8 includes a rotating drive mechanism 81 and a rotating seat 82 disposed at the output end of the rotating drive mechanism 81. The rotating drive mechanism 81 of this invention is preferably a conventional rotary motor. The bottom of the rotating seat 82 has a first material passage for accommodating material on the conveyor belt 2. The width of the first material passage corresponds to the width of the material. Specifically, the rotating seat 82 includes a horizontally arranged cross plate 821 and slidably disposed below both sides of the cross plate 821. A first material passage is formed between the two stop plates 822. Sliding grooves 823 are provided at both ends of the top surface of the cross plate 821.

The top surface of the slide groove 823 of the 21 is provided with locking holes 824 at the fixed parts at both ends of the two stop plates 822 corresponding to the position above the slide groove 823. The stop plates 822 are fixed to the slide groove 823 by screwing fasteners into the locking holes 824. Before use, the fasteners are loosened and the positions of the two stop plates 822 are adjusted so that the width of the first material passage corresponds to the width of the material. After adjustment, the fasteners are tightened to fix the stop plates 822 to the horizontal plate 821. Preferably, a baffle plate 825 is provided at the end of the horizontal plate 821 away from the first blocking component 5 corresponding to the position of the first material passage to prevent the material from falling out of the first material passage when the rotating component 8 drives the material to rotate.

[0027] Preferably, the rotating assembly 8 also includes a lifting cylinder 83 mounted on the frame 100. The lifting cylinder 83 is arranged vertically, and the rotating motor is fixed at the output end of the lifting cylinder 83. This arrangement enables the rotating assembly 8 to have a lifting function. When the material is qualified, the lifting cylinder 83 drives the rotating assembly 8 to rise, thus avoiding any impact on the normal material conveying.

[0028] Preferably, the feeding mechanism of this utility model further includes a discharge trough 9, which is arranged obliquely and located obliquely below the flipping component 4. The discharge trough 9 is provided with a discharge channel, and the discharge trough 9 is provided with a first feed inlet 91, a second feed inlet 92 and a discharge outlet 93 corresponding to the discharge channel.

[0029] like Figure 1 and Figure 4 As shown, the flipping assembly 4 of this utility model includes a flipping shaft 41, a flipping seat 42 sleeved on the flipping shaft 41, and a flipping drive mechanism for driving the flipping shaft 41 to flip.

A second blocking assembly 43 is provided at the outlet of the second material passage. Specifically, the flipping mechanism also includes a support plate 44 for supporting the flipping seat 42. The flipping shaft 41 is located in the middle of the support plate 44.

When the flipping seat 42 is located at one end of the support plate 44, the second material passage corresponds to the first feeding port 91. When the flipping seat 42 is located at the other end of the support plate 44, the second material passage corresponds to the second feeding port 92.

[0030] Preferably, the tilting drive mechanism includes a driving gear 45 and a driven gear 46 meshing with each other, and a tilting drive cylinder 47 for driving the driving gear 45 to rotate. Specifically, the tilting drive mechanism also includes a mounting base 48, in which the driving gear 45 and the driven gear 46 are fixedly mounted. The tilting shaft 41 is fixedly mounted at the center of the driven gear 46. The tilting drive cylinder 47 is fixed on the mounting base 48 and located on the side of the driving gear 45 away from the driven gear 46. The tilting drive cylinder 47 is obliquely arranged, and the output end of the tilting drive cylinder 47 is fixed to the driving gear 45 through a connecting shaft, so that when the output end of the tilting drive cylinder 47 extends or retracts, it can drive the driving gear 45 to rotate, thereby driving the driven gear 46, the tilting shaft 41, and the tilting base 42 to rotate.

[0031] Preferably, the first blocking assembly 5 includes a vertically arranged first blocking cylinder 51 and a first blocking plate 52 fixed to the output end of the first blocking cylinder 51, with the output end of the first blocking cylinder 51 facing the conveyor belt 2.

[0032] Preferably, the second blocking assembly 43 includes a second blocking cylinder 431 arranged at an angle and a second blocking plate 432 fixed at the output end of the second blocking cylinder 431, with the output end of the second blocking cylinder 431 facing the discharge port of the second material passage.

[0033] Preferably, the first feeding trough 1 has a first feeding channel in the middle, and the second feeding trough 3 has a second feeding channel in the middle. The discharge port of the first feeding trough 1 is provided with a material distribution mechanism 11 for blocking the material in the first feeding channel. It should be noted that the structure of the above-mentioned material distribution mechanism 11 can adopt the conventional structure existing in the art, such as the material distribution mechanism disclosed in Chinese Utility Model Patent Application No. "202422076857.3" entitled "A Pull-out Conveying Device for a Pull-out Assembly Machine". The structure of the material distribution mechanism 11 is described in detail in that patent, and will not be described in detail here. As long as the material in the first feeding channel can fall onto the conveyor belt 2 one by one, it is acceptable.

[0034] Preferably, the pushing component 7 is located below the vision inspection module 6. The pushing component 7 includes a horizontally arranged pushing cylinder 71 and a pushing plate 72 fixed to the output end of the pushing cylinder 71. The output end of the pushing cylinder 71 faces from one side of the conveyor belt 2 to the other side. Correspondingly, one side of the conveyor belt 2 is provided with a receiving trough 73 for receiving the material pushed out by the pushing cylinder 71. The receiving trough 73 is fixed on the frame 100.

[0035] The feeding mechanism of this utility model also includes a control module. The controller 10, the first blocking cylinder 51, the vision inspection module 6, the pushing cylinder 71, the rotary drive mechanism 81, the flipping drive cylinder 47, and the second blocking cylinder 431 are all connected to the control module. It should be noted that the vision inspection module 6 of this utility model is a commercially available product in the field. Before use, the standard pattern of the required material is entered into the vision inspection module 6. When the material is located below the vision inspection module 6, the material is visually inspected.

[0036] The working principle of the feeding mechanism of this utility model is as follows: The material is laid flat in the first feeding trough 1. Under the action of the material distribution mechanism 11, it falls from the discharge port of the first feeding trough 1 onto the conveyor belt 2. At this time, the first blocking cylinder 51 retracts, and the control module controls the conveyor belt 2 to transport the material to the area below the vision inspection module 6 for vision inspection. Then, the control module controls other components to perform corresponding actions according to different vision inspection results. First: If the material matches the standard pattern in the vision inspection module 6 and is qualified, the conveyor belt 2 will continue to rotate and send the qualified material into the second discharge trough 3. At this time, the second blocking cylinder 431 will drive the second blocking plate 432 to retract, so that the qualified material can pass smoothly through the second material passage, enter the discharge trough 9 from the first inlet 91 and slide down from the drop outlet 93. Second: If the material does not match the standard pattern in the vision inspection module 6, the non-compliance is due to the product identification or product shape not conforming to the standard pattern. Then the push cylinder 71 is activated to directly push the non-compliance material into the receiving trough 73. Third: If the material matches the standard product label and product shape in the visual inspection module 6, but the front and back directions of the material are opposite and the front and back sides are opposite, the conveyor belt 2 will send the material to the rotating component 8 and then stop. At this time, the lifting cylinder 83 will drive the rotating component 8 to move down so that the material is in the first material passage. The rotating drive mechanism 81 will drive the rotating seat 82 to rotate so that the material will be reversed 180° to adjust the front and back direction. Then the lifting cylinder 83 will drive the rotating component 8 to rise. The conveyor belt 2 will send the material to the second discharge trough 3 and make the material fall into the second material passage of the flipping seat 42. At this time, the second blocking cylinder 431 will extend to block the material. Then the flipping cylinder will extend to drive the drive gear 45 and the driven gear 46 to rotate, so that the flipping shaft 41 will drive the flipping seat 42 to flip 180°. The flipping seat 42 will flip from one end of the bearing plate 44 to the other end, so that the material is adjusted to the front and back direction. After that, the material will enter the discharge trough 9 from the second feed port 92 and slide down from the drop port 93. If the material is only defective in the case of reversed front and back direction, the rotating component 8 will rotate the material 180° to correct the front and back direction, and the conveyor belt 2 will continue to rotate to feed the material into the second discharge trough 3. The second blocking cylinder 431 will retract, so that the material can pass smoothly through the second material passage, enter the discharge trough 9 from the first feed port 91 and slide down from the drop port 93. If the material is only defective in one case, with the front and back sides reversed, the conveyor belt 2 will directly send the material into the second feeding trough 3 and cause the material to fall into the second material passage of the tilting seat 42. At this time, the second blocking cylinder 431 will extend to block the material and perform the above-mentioned tilting action.

[0037] It should be noted that the discharge port 93 of the discharge trough 9 of this utility model corresponds to the subsequent production station. For example, if the material being detected is a zipper head, the discharge port 93 is aligned with the zipper head conveying device of the subsequent zipper assembly machine. If the material being detected is a zipper sheet, the discharge port 93 is aligned with the zipper sheet conveying device of the subsequent zipper assembly machine. In this way, by using the feeding mechanism of this utility model, the front and back sides and front and back directions of the material can be detected and adjusted to facilitate the work of the subsequent station and save labor costs.

[0038] After the visual inspection module 6 detects the material, the flipping feeding mechanism of this utility model can automatically adjust the orientation of materials with different orientations through the rotating component 8, and automatically adjust the front and back of materials with different orientations through the flipping mechanism 4. It has a high degree of automation, saves labor costs, and effectively improves the efficiency of material detection and production operation.

[0039] 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.
