[0002] In the field of modern industrial manufacturing, the production volume of parts is huge and the quality requirements are becoming increasingly stringent. As the scale of production continues to expand, the traditional way of manually inspecting and sorting parts faces many challenges. Manual inspection is not only inefficient, but also easily affected by subjective factors, resulting in frequent misjudgments and missed judgments. This not only increases production costs and reduces production efficiency, but may also cause unqualified parts to flow into subsequent processes, affecting the quality and performance of the entire product, and causing a series of quality problems and after-sales disputes.

[0003] In addition, with the continuous advancement of the concept of intelligent manufacturing, factories have an increasingly urgent need for automated production equipment. Some existing parts detection and classification devices either have a single function and can only achieve simple detection or classification functions, which cannot meet complex production needs; or have complex structures and high costs, which are not conducive to large-scale promotion and application. For example, some devices have low accuracy in identifying part defects, or are prone to secondary damage to parts during the classification process, affecting the use value of the parts.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 8 The present invention presents a technical solution: a defective parts intelligent identification and classification device, which is mainly composed of a control box 1, a frame 2, a crawler track 3, a conveyor belt 4, a collection box 5, an isolation plate 6, a vertical plate 7, a horizontal plate 8, a conveyor belt motor 9, a chain 10, a telescopic rod 11, a mechanical claw A, a transmission shaft gear 12, a side gear 13, an active wheel disc 14, a camera 15, a passive wheel disc 16, a conveyor belt rotating rod 17, a mechanical claw vertical motor 18, a vertical threaded rod 19, a support wheel 20, a crawler track motor 21, a support column 22, a claw head 23, an adjustment rod 24, an adjustment rod motor 25, a hook 26, an adjustment disk 27, a horizontal motor 28, a fixing plate 29, a threaded rod fixer 30, a connector 31, and a horizontal threaded rod 32.

[0027] See also Figure 1-Figure 8 As the best embodiment of the present invention, the overall transmission area is mainly composed of a control box 1, a crawler track 3, a passive wheel disc 16, a driving wheel disc 14, a support wheel 20, a crawler track motor 21, a transmission shaft gear 12, a side gear 13 and other components.

[0028] The control box 1 is located on the side of the frame 2, and its main function is to realize the control operation of the overall system of the device. The operator can accurately adjust the operating status of the device through various control buttons on the control box 1, such as starting, stopping, accelerating, decelerating and other operations. At the same time, the display on the control box 1 can feedback the operating parameters and status information of the device in real time, so that the operator can understand the working status of the device in time and make corresponding decisions.

[0029] The crawler motor 21 is located inside the crawler 3 and is the power source of the entire transmission area. The crawler motor 21 drives the crawler 3 to rotate by outputting torque, providing necessary power support for the movement of the device, and its design can effectively reduce the unit pressure on the ground, so that the device has less impact on the ground during operation, and is suitable for a variety of different ground environments.

[0030] The side gear 13 is located behind the transmission shaft gear 12, below the conveyor belt 4, and above the support wheel 20. It closely cooperates with the transmission shaft gear 12 to complete the transmission and conversion of power. The side gear 13 further transmits the power received from the transmission shaft gear 12 to the driving wheel 14. Through the meshing between the gears and the setting of the transmission ratio, the moving speed and direction of the device are precisely controlled, so that the device can flexibly adjust the operating state according to actual work needs.

[0031] The working principle of the overall transmission area is as follows: when the operator issues a start command on the control box 1, the control box 1 sends an electrical signal to the track motor 21 to start the track motor 21. The track motor 21 starts working and outputs torque, which is transmitted to the side gear 13 through the transmission shaft gear 12. After receiving the torque, the side gear 13 drives the driving wheel 14 to start rotating. The driving wheel 14 is tightly meshed with the track 3, converting the rotational motion into the linear motion of the track 3, so that the device as a whole starts to move. In this process, the passive wheel 16 and the support wheel 20 work together. The passive wheel 16 assists the track 3 to maintain a stable running track, and the support wheel 20 continuously disperses the pressure of the device on the ground to ensure the stability and stability of the device during movement. By accurately controlling the output torque, speed and other parameters of the track motor 21 by the control box 1, various different moving operations such as forward, backward, and steering of the device can be realized, so that the device can adapt to different work sites and task requirements, such as precise movement in a narrow space, or stable driving on complex terrain.

[0032] See also Figure 1-Figure 8 As the best implementation mode of the present invention, the conveyor belt area is the key area for realizing continuous transportation and effective sorting of items, and mainly includes components such as conveyor belt 4, conveyor belt motor 9, chain 10, conveyor belt rotating rod 17 and collection box 5.

[0033] The conveyor belt 4 is located behind the collection box 5, and its main function is to carry and transport the items to be sorted. The surface of the conveyor belt 4 has a certain friction force, which can ensure that the items remain stable during transportation and will not easily slip or shift. At the same time, the conveyor belt 4 is tightly connected with the conveyor belt motor 9 and the chain 10 to form a complete power transmission system, ensuring that the items can move continuously and smoothly on the conveyor belt 4, providing a stable item flow for subsequent sorting work.

[0034] The conveyor belt motor 9 is installed below the conveyor belt 4 and above the partition 6. It is the power provider for the operation of the conveyor belt 4. The conveyor belt motor 9 converts electrical energy into mechanical energy through the internal electromagnetic induction principle, generates torque, and drives the conveyor belt 4 to rotate. The torque output can be adjusted according to actual work needs. Through the control of the control box 1, the operator can accurately adjust the speed of the conveyor belt motor 9, thereby realizing the control of the running speed of the conveyor belt 4. In this way, in different work scenarios, such as transporting small and light items, the speed can be increased to improve efficiency, and when transporting large and heavy items, the speed can be reduced to ensure stability.

[0035] The conveyor belt rotating rod 17 is located at the rear side of the conveyor belt 4. It is connected to the conveyor belt motor 9 and the chain 10. Its main function is to support the conveyor belt 4, maintain the smooth operation of the conveyor belt, and reduce energy consumption. During the operation of the conveyor belt 4, the conveyor belt rotating rod 17 rotates synchronously with the rotation of the conveyor belt, and effectively reduces the energy consumption required for the operation of the conveyor belt 4 by reducing the friction between the conveyor belt 4 and the supporting structure. In addition, the position and height of the conveyor belt rotating rod 17 can be adjusted according to actual conditions to ensure that the conveyor belt 4 can maintain the best operating state under different working conditions, such as different loads, different object sizes, etc., to ensure the stability and accuracy of the objects during the transmission process.

[0036] The collection box 5 is located inside the frame 2. It is a container for temporarily storing conveyed items. Its internal structure is specially designed to place high-quality and low-quality items in batches. The collection box 5 is divided into two independent boxes on the left and right, each of which is equipped with a ramp and a gate. When the parts transported by the conveyor belt 4 and sorted by the mechanical claw A arrive above the collection box 5, the parts will fall into the two boxes on the left and right according to the sorting results. The design of the slope allows the parts to slide smoothly into the box under the action of gravity, which is convenient for collection and sorting; the gate can be closed when necessary to prevent parts from falling or being mixed up, ensuring the accuracy and stability of the collection process. For example, after a batch of parts is sorted, the gate can be closed, and the collected high-quality parts and defective parts can be centrally processed or transferred to the next process.

[0037] The working principle of the conveyor belt area is as follows: First, the operator starts the conveyor belt motor 9 through the control box 1, and the conveyor belt motor 9 starts to work and generates a rotating force. The rotating force is transmitted to the conveyor belt rotating rod 17 through the chain 10. After receiving the power, the conveyor belt rotating rod 17 starts to rotate, driving the conveyor belt 4 connected thereto to rotate synchronously. At this time, the parts to be sorted are continuously placed on the conveyor belt from the front of the conveyor belt 4. As the conveyor belt 4 continues to rotate, the parts are smoothly transported backward. When the parts are transported to the position where the mechanical claw A is located, the camera 15 identifies the parts and determines whether they are good or bad. According to the recognition results, the mechanical claw A distinguishes the parts from left to right, and the good parts are placed on one side of the conveyor belt 4, and the defective parts are placed on the other side. As the conveyor belt 4 continues to run, the parts separated from the left and right are respectively placed in the left and right boxes of the collection box 5, completing the entire process of sorting and collecting the items. In this process, the various components of the conveyor belt area work closely together and work together to ensure that the items can be accurately and efficiently transported, sorted and collected.

[0038] See also Figure 1-Figure 8 As the best implementation mode of the present invention, the mechanical arm area is the core part for realizing accurate sorting of parts, and it is composed of a mechanical claw A, a vertical plate 7, a horizontal plate 8, a mechanical claw vertical motor 18, a vertical threaded rod 19, a camera 15, a claw head 23, an adjusting rod 24, an adjusting rod motor 25, a hook 26, an adjusting disk 27, a horizontal motor 28, a fixing plate 29, a threaded rod fixer 30, a connector 31, a horizontal threaded rod 32 and other components.

[0039] The vertical plate 7 is located below the top of the frame 2. Its main function is to provide stable support and precise fixed position for the mechanical claw vertical motor 18, vertical threaded rod 19 and other components. The vertical plate 7 has a solid structure and sufficient strength and rigidity to withstand various forces generated by the mechanical arm area during operation, such as the pulling force when the mechanical claw A grabs parts, the axial force generated when the vertical threaded rod 19 is raised and lowered, etc., to ensure that the mechanical arm moves smoothly and reliably in the vertical direction without shaking or offset. At the same time, the vertical plate 7 is also equipped with guide devices, which work closely with the vertical threaded rod 19 to guide the vertical threaded rod 19 to maintain linear motion during the lifting process, further improving the position accuracy of the mechanical claw A in the vertical direction.

[0040] The transverse plate 8 is located below the vertical plate 7, and it provides a solid support platform for the adjustment plate 27, the transverse motor 28, the fixing plate 29, the threaded rod fixing device 30 and other components. The transverse plate 8 and the vertical plate 7 are perpendicular to each other, and the two together construct the basic framework structure of the robot arm area, providing a basic guarantee for the movement of the robot arm in the horizontal and vertical directions. The various components on the transverse plate 8 work together to achieve precise movement and angle adjustment of the mechanical claw A in the horizontal direction, so that the mechanical claw A can quickly and accurately locate the position of the target part on the horizontal plane, improving the sorting efficiency and accuracy.

[0041] The vertical threaded rod 19 is located above the vertical plate 7 and below the horizontal plate 8. It closely cooperates with the mechanical claw vertical motor 18 to convert the rotational motion output by the mechanical claw vertical motor 18 into linear motion, driving the mechanical claw A to rise and fall smoothly in the vertical direction. The vertical threaded rod 19 has good load-bearing capacity and transmission accuracy. Its surface has been finely processed, and the pitch and tooth shape of the thread are reasonably designed, which can ensure that under the drive of the mechanical claw vertical motor 18, the mechanical claw A has high position accuracy and movement stability during the lifting process. The vertical threaded rod 19 cooperates with the threaded rod fixture 30 to achieve the lifting and lowering movement of the mechanical claw A while maintaining its own stable rotation, reducing the impact of friction and vibration on the movement accuracy of the robot arm.

[0042] The camera 15 is located below the vertical plate 7 and behind the mechanical claw A device. It is a key device for realizing intelligent sorting in the mechanical arm area. The camera 15 adopts advanced optical imaging technology and image recognition algorithm, which can quickly and accurately capture the image information of parts, including the shape, size, surface features, etc. of the parts, and transmit these image information to the control box 1 in real time. The image processing system in the control box 1 analyzes and processes the received image, judges the quality, type and other information of the parts according to the preset recognition standards, and sends the sorting instructions to other components in the mechanical arm area. For example, on the parts production line, the camera 15 can quickly identify the defects and dimensional deviations on the surface of the parts, providing a reliable basis for the accurate sorting of the mechanical claw A.

[0043] The adjusting rod motor 25 is connected to the adjusting rod 24, the claw head 23 and the mechanical claw A, and it is the power provider for the movement of the adjusting rod 24. The adjusting rod motor 25 accurately controls the movement of the adjusting rod 24, including the telescopic length, rotation angle and movement speed of the adjusting rod 24, by receiving the control signal sent by the control box 1. The adjusting rod motor 25 adopts a high-precision motor drive system and position feedback device inside, which can realize the precise control of the movement of the adjusting rod 24, ensuring that the adjusting rod 24 can accurately reach the predetermined position during the movement process, and meet the various posture requirements of the mechanical claw A for grasping parts.

[0044] The adjustment disk 27 is located below the adjustment rod 24 and is connected to the gripping head 23. The adjustment disk 27 is an important component for achieving precise adjustment of the claw head 23. By rotating the adjustment disk 27, the position and angle of the claw head 23 can be fine-tuned. The adjustment disk 27 is usually engraved with precise scale marks. The operator can adjust the position of the claw head 23 in the horizontal and vertical directions by rotating the adjustment disk 27 to the corresponding scale position according to actual needs, thereby further improving the accuracy and stability of the mechanical claw A in grasping parts.

[0045] The threaded rod holder 30 contains rollers inside, and the rollers can rotate with the rotation of the vertical threaded rod 19. The main function of the threaded rod holder 30 is to support the rotational movement of the vertical threaded rod 19 brought by the vertical motor 18 of the mechanical claw while fixing the vertical threaded rod 19. The design of the threaded rod holder 30 effectively reduces the friction between the vertical threaded rod 19 and the fixed structure during the rotation process, and improves the efficiency and stability of the lifting and lowering movement of the mechanical claw A. At the same time, the threaded rod holder 30 can also prevent the vertical threaded rod 19 from axial displacement during the working process, ensuring the movement accuracy and repeatability of the mechanical claw A in the vertical direction.

[0046] The connector 31 is fixed on the fixed plate 29, and it connects the vertical threaded rod 19, and connects the transverse plate 8 to the vertical threaded rod 19. Through the rotation of the vertical motor 18 of the mechanical claw, the connector 31 can cooperate with the vertical threaded rod 19 to complete the vertical movement of the transverse plate 8. The structural design of the connector 31 is ingenious. It can transmit the torque of the vertical threaded rod 19 while ensuring that the transverse plate 8 remains stable during the vertical movement without shaking or tilting. The existence of the connector 31 enables all components on the transverse plate 8 to perform precise lifting and lowering movements together with the vertical plate 7, thereby realizing the overall position adjustment of the robotic arm in the vertical direction and improving the robotic arm's ability to grasp parts of different heights.

[0047] The transverse threaded rod 32 has the same principle as the vertical threaded rod 19 and is adjusted by the transverse motor 28 .

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
