Description

Technical Field

[0001] This utility model belongs to the technical field of diversion equipment, and in particular relates to an automatic diversion equipment for defective products. Background Technology

[0002] Defective product diversion refers to the process in industrial production where products that do not meet quality standards are identified, sorted, and separated from the normal material flow using automated technology. The core purpose is to improve product qualification rate and reduce labor costs.

[0003] Before the widespread adoption of automation technology, the sorting of defective products mainly relied on manual operation (workers inspected materials one by one by visual observation, touch, or simple tools, and manually picked out defective products). However, this method was inefficient, and manual inspection was affected by fatigue and subjective judgment, resulting in unstable accuracy.

[0004] To address the drawbacks of manual sorting, existing technologies are gradually adopting an automated solution of "conveyor belt transport + mechanical / pneumatic diversion": materials are continuously transported using belt or chain conveyor belts, and defects are identified at the inspection station using industrial cameras or sensors. When a defective product is detected, mechanical push rods, pneumatic nozzles, or other devices are triggered to forcibly push the material away from the main conveyor line. However, in existing technical solutions, when mechanical push rods push materials or pneumatic blowing occurs, relative sliding occurs between the material and the conveyor belt, which can easily lead to surface scratches.

[0005] Therefore, it is essential to invent an automatic sorting device for defective products. Utility Model Content

[0006] To address the above problems, this utility model proposes an automatic sorting device for defective products, and the technical solution used is as follows:

[0007] An automatic sorting device for defective products includes a housing, rotating columns, chain links, a first motor, a discharge mechanism, a vision camera, support frames, and a power supply mechanism. Two rotating columns are rotatably mounted inside the housing via support bearings. The outer surfaces of the rotating columns are wrapped with chains, which are composed of several chain links connected end-to-end. The power supply terminals of the chain links are electrically connected to the power supply terminals of the power supply mechanism, which is fixed to the housing by bolts. The power supply mechanism's power supply terminals are electrically connected to an external power source via power lines. The first motor is bolted to the outer surface of the housing, and its output terminal is fixed to one of the rotating columns. The discharge mechanism is bolted to the upper end of the housing and positioned between the two rotating columns. Several support frames are bolted to the sides of the housing, and vision cameras are bolted to the upper ends of each support frame. The vision cameras are respectively mounted on the upper sides of corresponding chain links. The chain links, the first motor, and the vision cameras are all connected to an external production computer via data cables, and their power interfaces are all electrically connected to an external power source via power lines.

[0008] Furthermore, the chain link includes a hinge plate, a first frame, a first transmission column, a first belt, a second motor, and a wireless transceiver module. Both ends of the hinge plate are provided with corresponding hinge joints, and the upper side of the hinge plate is fixed to the first frame by bolts. At least two first transmission columns are rotatably mounted inside the first frame via support bearings, with the outer surface of each first transmission column encasing the first belt. The outer surface of the first frame is fixed to the second motor by bolts, with the output end of the second motor fixed to one of the first transmission columns. The wireless transceiver module is fixed to the first frame by bolts, and is connected to the second motor via a data cable and also wirelessly connected to an external production computer. The power interfaces of the second motor and the wireless transceiver module are electrically connected to the power supply terminal of the power supply mechanism via power cables. This configuration allows the material being carried to be discharged onto the discharge mechanism under the control of an external production computer, through the cooperation of the second motor, the first transmission column, and the first belt. Since there is no relative movement between the material and the first belt, no damage is caused to the material.

[0009] Furthermore, the power supply mechanism includes a slide rail, a first conductive sheet, a second conductive sheet, and sliding columns. The slide rail is fixed to the housing by bolts, and the first conductive sheet is fixed inside the slide rail. One end of the first conductive sheet is electrically connected to an external power source, and the other end of the first conductive sheet is attached to several second conductive sheets. The second conductive sheets are respectively fixed to the outer surface of the corresponding sliding columns, wherein the sliding columns are all slidably connected to the slide rail, and one end of the sliding columns is respectively fixed to the corresponding hinge plate. The second conductive sheets are electrically connected to the corresponding second motor and wireless transceiver module through power lines. This arrangement enables power supply to the second motor and the wireless transceiver module.

[0010] Furthermore, the material discharge mechanism includes a mounting plate, a second frame, a second transmission column, a second belt, and a third motor. The mounting plate is fixed to the upper end of the housing with bolts and is positioned between two rotating columns. The length of the mounting plate is greater than the width of the chain link, and several second frames are fixed to the upper end of the mounting plate with bolts. Each second frame has at least two second transmission columns installed inside, and the outer side of each second transmission column is wrapped with a second belt, which is positioned below the corresponding vision camera. A third motor is fixed to the outer side of each second frame with bolts, and the output end of the third motor is fixed to the corresponding second transmission column. The third motor is electrically connected to an external power source via a power cord and to an external production computer via a data cable. This configuration allows for the discharge of materials from the chain link.

[0011] Furthermore, the outer surface of the second belt is covered with a flexible pad, which can prevent material from being damaged when it falls from the chain link onto the second belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention allows materials to be placed on corresponding chain links at one end of the housing. The chain links then move accordingly via the cooperation of a first motor and a rotating column, passing sequentially through corresponding vision cameras. When the material meets the detection criteria of one of the vision cameras (e.g., a printing problem or surface damage), the material is discharged onto a discharge mechanism via the cooperation of a second motor, a first transmission column, and a first belt. Since there is no relative movement between the material and the first belt, no damage is caused to the material. When the material reaches the position of the last vision camera, it is considered normal material that meets the requirements. Furthermore, the power supply mechanism ensures normal power supply to the second motor and the wireless transceiver module during the movement of the chain links. Attached Figure Description

When the chain link 3 moves to the underside of the vision camera 6, if the material meets the detection state of the vision camera 6, the wireless transceiver module 36 can control the second motor 35 to work under the control of the external production computer, and then transport the material to the discharge mechanism 5 through the cooperation of the first transmission column 33 and the first belt 34. Since the material is discharged by the movement of the first belt 34, there is no relative movement between the material and the first belt 34, so it will not cause damage to the material.

Then, through the cooperation of the first motor 4 and the rotating column 2, the chain link moves accordingly and passes through the corresponding vision cameras 6 in sequence. When the material meets the detection status of one of the vision cameras 6 (for example, there is a printing problem or the appearance is damaged), the material can be discharged onto the discharge mechanism 5 through the cooperation of the second motor 35, the first transmission column 33 and the first belt 34. The material is then discharged through the discharge mechanism 5. When the material moves to the position of the last vision camera 6, the material is a normal material that meets the requirements.
