Description

Technical Field

[0001] The present invention relates to the field of automated detection, and in particular to a material transmission device. Background Art

[0002] As visual inspection is increasingly used in product surface inspection, it photographs products and performs image analysis and processing to screen out qualified and unqualified products. However, it also requires multi-angle inspection of a large number of products at the same time, and there is currently a lack of standardized inspection equipment.

[0032] Reference Figures 1 to 8 In some embodiments, the technical solution of the present invention is a material transmission device, referring to Figure 1 and Figure 8 , the material transmission device includes: A base 100, wherein a processing mechanism is provided inside the base 100; A workpiece transfer mechanism, which is used to transfer materials placed in the material tray. The workpiece transfer mechanism includes a first workpiece transfer mechanism 200 and a second workpiece transfer mechanism 500.

The conveying mechanism 300 is provided between the first workpiece transfer mechanism 200 and the second workpiece transfer mechanism 500 , and the conveying mechanism 300 is electrically connected to the processing mechanism.

[0033] The beneficial effects of the present invention are: The material transfer device can sequentially capture a top view, side view, and top line-of-sight image of the product being tested. The top view primarily checks whether the length of the product meets requirements, while the side view and top line-of-sight image primarily check whether the thread of the product meets requirements. The captured images are then processed to determine whether qualified and unqualified products are present. Unqualified products are then classified and temporarily stored according to their type, and qualified products are separated and stacked, achieving the technical effect of automated visual inspection. The material transfer device can improve the efficiency of automated product inspection.

[0034] Specifically, the workpiece to be measured is placed on the material tray of the first workpiece transfer mechanism 200, which is provided with a plurality of slots. The workpiece to be measured is arranged in each slot in turn. When the inspection is carried out, each slot of each material tray is transferred by the first workpiece transfer mechanism 200 to the first turntable mechanism 320. The first turntable mechanism 320 transfers the workpiece to be measured one by one to the fixture 312 on the inspection belt 310. The workpiece to be measured passes through the front-view camera mechanism 410, the lifting and rotating mechanism 420 and the line scanning camera mechanism 440 of the inspection part 400 in turn. The front-view camera mechanism 410, the lifting and rotating mechanism 420 and the line scanning camera mechanism 440 collect the image of the workpiece to be measured and the processing mechanism determines whether the workpiece is qualified, and classifies and marks the unqualified types. Finally, the tested workpiece to be measured is replaced on the corresponding classification tray through the unloading structure.

[0035] In other embodiments, the workpiece transfer mechanism and the conveying mechanism 300 are provided in multiple numbers, the first workpiece transfer mechanism 200, the conveying mechanism 300 and the second workpiece transfer mechanism 500 are connected in sequence, and multiple sets of workpiece transfer mechanisms and conveying mechanisms 300 can be provided to realize multiple detections and long-distance linear or non-linear transportation operations.

[0039] By analogy, in actual applications, since the distance required for transmission or the combination of items that need to be detected during transmission varies according to actual detection requirements, a combination of multiple sets of workpiece transfer mechanisms and conveying mechanisms 300 can be set, that is, a combination of workpiece transfer mechanism 200 -> conveying mechanism 300 -> second workpiece transfer mechanism 500, so as to achieve the technical effects of transmission, detection and classification as a whole.

A first transfer working area 260 is provided between the first jacking platform 220 and the second jacking platform 240.

There are two first side cylinders 223 and two first side push plates 224 respectively. The first transfer work area 260 is provided with a first pressing plate group 261 for pressing the material trough and a fourth cylinder 262 for lifting and lowering the first pressing plate group 261. The first pressing plate group 261 includes a first pressing plate 263 and a second pressing plate 264 arranged in parallel. The width between the first pressing plate 263 and the second pressing plate 264 is the width of a single material trough of the material tray. The output shaft of the second cylinder 233 of the first moving module 230 can extend into the gap between the first pressing plate group 261. The ends of the first pressing plate 263 and the second pressing plate 264 are respectively provided with a first beam sensor 265 for detecting the length of the workpiece.

[0041] Specifically, a plurality of material trays with workpieces to be measured are provided on the first lifting platform 220, and the first cylinder 221 controls the first lifting plate 222 to rise. After the first side cylinder 223 is released, the material tray at the bottom falls smoothly on the first lifting plate 222, and the first cylinder 221 controls the first lifting plate 222 to descend until the material tray at the upper grid moves down to the height of the output shaft of the first side cylinder 223, and the first side cylinder 223 continues to move downward until the material tray is placed on the first conveyor belt 250, and the first conveyor belt 250 moves, and aligns the material trough on the material tray with the gap of the first pressure plate group 261 and the first turntable 321 in turn. At this time, the first moving module 230 moves to the starting end of the material trough, and the first push block 232 and the first shift rod 234 move the workpiece on the material trough. The first turntable 321 is pushed in sequentially along the direction of the first pressure plate group 261, and the first turntable 321 transfers the workpieces to the detection belt 310 sequentially. When all the workpieces of a trough are pushed in, the first conveyor belt 250 drives the material tray to move to the next trough, and repeats the above operation until the workpieces of all the troughs are transferred. The first conveyor belt 250 drives the material tray to move to the position of the second jacking platform 240. At this time, the first jacking platform 220 repeats the above work to transfer the material tray at the lowest position to the first conveyor belt 250, and the second jacking plate 242 of the second jacking platform 240 raises the material tray and pushes open the first hinge 243. When the material tray rises into place, the second jacking plate 242 will begin to descend and return to its original position. At this time, the first hinge 243 clamps the material tray to prevent the material tray from falling down.

[0042] The first limiting block 252 is used to limit the position of the material tray and solve the alignment of the material tray, the material trough and other components.

S360: Whenever all the workpieces to be tested in a certain slot of the tray in the second transfer work area 570 are filled, the eighth cylinder 580 controls the second pressing plate group 571 to move upward until it breaks contact with the material slot on the tray and stops at a preset height. The second conveyor belt 560 rotates so that the next slot of the tray is aligned with the gap of the second pressing plate group 571. Steps S340 and S350 are repeated until all the slots of the current tray are filled with qualified workpieces. S370: The second conveyor belt 560 rotates, causing the current tray to completely leave the first transfer work area 260 and arrive at the fourth lifting platform 550. The first zero cylinder 551 controls the fourth lifting plate 552 to lift the tray filled with qualified workpieces upward until the second hinge 553 is opened to a preset height, then stops and slowly descends.
