Description

Technical Field

[0001] The present invention relates to the technical field of part stacking, and more particularly to an automatic small part stacking and sorting device. Background Art

[0002] In today's manufacturing environment, the processing of small parts is a delicate and large-scale task. Currently, after the small parts are processed, it is necessary to first clean the impurities on their surfaces, because the presence of impurities may affect the subsequent use performance of the parts and the accuracy of quality inspection. However, this cleaning work mainly relies on manual operation. Workers need to hold various cleaning tools, such as brushes, rags, etc., to remove metal debris, dust and other impurities attached to the surface of the parts. This method is not only inefficient, especially when dealing with a large number of parts, the time cost of manual cleaning one by one is extremely high, seriously restricting the progress speed of the entire production process.

[0003] Subsequently, the workers need to place the cleaned small parts on the electronic scale one by one, staring closely at the display screen of the scale to observe whether the reading is within the specified manufacturing requirements. This process requires a high degree of concentration and precise operation. Repeating such actions for a long time, workers tend to feel fatigued and it is difficult to always maintain concentration, thus prone to mistakes, such as misreading the reading, misplacing the parts, weighing repeatedly or missing inspections, etc., resulting in deviations in the test results, affecting the control of product quality, and even possibly allowing unqualified parts to flow into the next process, causing greater losses.

[0004] Therefore, those skilled in the art are committed to developing an automatic small part stacking and sorting device, which is conducive to automatic material taking, impurity removal, weighing and stacking, and improving the production efficiency of small parts. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic small part stacking and sorting device, which is conducive to automatic material taking, impurity removal, weighing and stacking, and improving the production efficiency of small parts.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: An automatic small part stacking and sorting device includes a clamping assembly, which is installed at the mobile end of the moving assembly and is used for clamping small parts conveyed by the conveyor belt assembly.

[0007] The beneficial effects of adopting the above solution are as follows: Through the coordinated work of the clamping component, moving component, cleaning component, weighing component and stacking component, automatic material taking, impurity removal, weighing and stacking placement of small parts after processing are realized. The whole process does not require manual operation one by one, greatly reducing manual intervention and waiting time, effectively improving the progress speed of the small part production process, significantly enhancing production efficiency, meeting the requirements of the manufacturing industry for high-efficiency production, especially suitable for processing scenarios of a large number of small parts, and can quickly complete heavy cleaning, detection and stacking work, bringing higher production efficiency and economic benefits to the enterprise; The automated cleaning component can remove impurities on the surface of small parts more thoroughly and evenly, ensuring the stability of cleaning quality, providing a more accurate basis for subsequent weighing and performance detection in use. The electrical connection between the weighing component and the control component can achieve accurate detection of the weight of each small part, avoiding mistakes such as misreading readings, misplacing parts, repeated weighing or missed inspection that may occur during manual weighing, thereby effectively improving the accuracy of quality detection, ensuring that only small parts that meet the manufacturing requirements can enter the next process, effectively guaranteeing product quality, reducing losses caused by unqualified products flowing into subsequent processes, and helping to improve the overall quality and market competitiveness of the enterprise's products.

[0031] As Figure 1 、 Figure 2 and Figure 3 shown, an automatic small part coding and sorting device includes a clamping assembly 1, which is installed on the mobile end of the mobile assembly 2 and is used for clamping small parts conveyed by the conveyor belt assembly 3. Both the clamping assembly 1 and the mobile assembly 2 are electrically connected to a control assembly 4, and the mobile assembly 2 is installed in a box body 5; a cleaning assembly 6, which is installed in the box body 5 and is used for cleaning small parts conveyed by the mobile assembly 2. The cleaning assembly 6 is electrically connected to the control assembly 4; a weighing assembly 7, which is installed in the box body 5 and is used for weighing small parts conveyed by the mobile assembly 2. The weighing assembly 7 is electrically connected to the control assembly 4; a stacking assembly 8, which is used for stacking small parts conveyed by the mobile assembly 2. The stacking assembly 8 is electrically connected to the control assembly 4.

[0032] In the present invention, through the collaborative work of the clamping component 1, the moving component 2, the cleaning component 6, the weighing component 7 and the stacking component 8, automatic material taking, impurity removal, weighing and stacking placement after the processing of small parts are realized. The whole process does not require manual operation one by one, greatly reducing manual intervention and waiting time, effectively improving the advancement speed of the small part production process, significantly enhancing production efficiency, meeting the requirements of the manufacturing industry for high-efficiency production, especially suitable for the processing and treatment scenarios of a large number of small parts, and can quickly complete heavy cleaning, detection and stacking work, bringing higher production efficiency and economic benefits to the enterprise. As Figure 1 , Figure 2 shown, in some embodiments, the clamping component 1 includes a clamping cylinder 9, the clamping cylinder 9 is installed on the moving end of the moving component 2, and a clamping finger 10 is installed at the output end of the clamping cylinder 9. The clamping cylinder 9 drives the clamping finger 10 to drive the first clamping finger and the second clamping finger to move away from each other and abut against the inner hole of the small part.

[0033] In the embodiment, the moving component 2 includes a vertical moving component. The vertical moving component includes a vertical moving frame 11. The vertical moving frame 11 is installed on the horizontal moving component 12, so that the entire vertical moving component can achieve a horizontal displacement driven by the horizontal moving component 12. Specifically, a vertical guide rail 35 is installed on the vertical moving frame 11, a vertical slider cooperating with the vertical guide rail is installed on the vertical guide rail 35, and a vertical moving plate 13 is installed on the vertical slider. The clamping component 1 is installed on the vertical moving plate 13. A vertical servo motor 14 is also installed on the vertical moving frame 11, and the vertical servo motor 14 is electrically connected to the control component 4. A vertical lead screw 15 is installed at the output end of the vertical servo motor 14, and a vertical lead screw bearing cooperating with the vertical lead screw 15 is installed on the vertical moving plate 13. The rotation of the vertical servo motor 14 drives the vertical moving plate 13 and the clamping component 1 to move vertically, thereby vertically moving the clamped small parts up and down.

[0034] As Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the lateral movement assembly 12 includes a lateral movement block 16, which is installed on the longitudinal movement assembly 17, so that it can achieve longitudinal displacement under the drive of the longitudinal movement assembly 17. Specifically, a lateral guide rail 18 is installed on the lateral movement block 16, a lateral slider that cooperates with the lateral guide rail 18 is installed on the lateral guide rail 18, and a lateral movement plate is installed on the lateral slider. The vertical movement assembly is installed on the lateral movement plate. A lateral servo motor 19 is also installed on the lateral movement block 16. The lateral servo motor 19 is electrically connected to the control assembly 4. A lateral lead screw 20 is installed at the output end of the lateral servo motor 19. A lateral lead screw bearing that cooperates with the lateral lead screw 20 is installed on the lateral movement plate. When the lateral servo motor 19 runs and rotates, by means of the transmission mechanism of the lateral lead screw 20 and the lateral lead screw bearing, the lateral movement plate and the vertical movement assembly thereon are precisely displaced in the lateral direction, thereby providing the clamping assembly 1 with the freedom of lateral movement.

[0035] As Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the longitudinal movement assembly 17 includes longitudinal movement blocks 21. Two longitudinal movement blocks 21 are installed on the inner wall of the box body 5. A longitudinal guide rail 22 is installed on the longitudinal movement blocks 21. A longitudinal slider that cooperates with the longitudinal guide rail 22 is installed on the longitudinal guide rail 22. A longitudinal movement plate 23 is installed on the longitudinal slider. The lateral movement assembly 12 is installed on the longitudinal movement plate 23. A longitudinal servo motor 24 is also installed on one of the longitudinal movement blocks 21. The longitudinal servo motor 24 is electrically connected to the control assembly 4. A longitudinal lead screw 25 is installed at the output end of the longitudinal servo motor 24. A longitudinal lead screw bearing that cooperates with the longitudinal lead screw 25 is installed on the longitudinal movement plate 23. When the longitudinal servo motor 24 starts and rotates, through the transmission action of the longitudinal lead screw 25 and the longitudinal lead screw bearing, the longitudinal movement plate 23 and the lateral movement assembly 12 thereon are precisely moved in the longitudinal direction, providing support for the processing operation of the entire device in the longitudinal dimension.

[0036] As Figure 1 , Figure 2As shown, in the embodiment, the cleaning assembly 6 is installed in the box body 5 and is mainly used for cleaning the small parts conveyed by the moving assembly 2. Specifically, the cleaning assembly 6 includes a cleaning platform 26, on which a cleaning head 27 is installed. The cleaning head 27 is connected to a compressed air pipe, and the airflow generated by the compressed air is used to blow off the impurities on the surface of the small parts. An electromagnetic valve is installed on the compressed air pipe, and the electromagnetic valve is electrically connected to the control assembly 4, which facilitates the control assembly 4 to accurately control the opening and closing of the cleaning head 27 according to the needs of the process flow, ensuring the automation and high efficiency of the cleaning operation.

[0037] The weighing assembly 7 is used for accurately weighing the small parts conveyed by the moving assembly 2. Specifically, the weighing assembly 7 includes a weighing platform 28, and the weighing platform 28 is electrically connected to the control assembly 4. This enables the control assembly 4 to obtain the weighing data in real time, and perform corresponding processing and judgment, thereby ensuring that the weight of the small parts meets the specified manufacturing requirements and guaranteeing the stability and consistency of the product quality.

[0038] As Figure 1 , Figure 2 As shown, in some embodiments, the stacking assembly 8 includes a stacking tray 29, the stacking tray 29 is arranged on the sliding rail assembly 30, and a handling assembly 31 and a stacking rack 32 are also arranged on the side wall of the sliding rail assembly 30. The handling assembly 31 is used to slide the stacking tray 29 along the sliding rail assembly 30 for a certain distance, and then stack it on the stacking rack 32 through the handling assembly 31.

[0039] The stacking rack 32 is installed on the discharging assembly 33, and the discharging assembly 33 can adopt a servo device. A waste bin 34 is also installed in the box body 5, and the waste bin 34 is used to collect the small parts with unqualified weighing, which is conducive to unified recycling and post-treatment. Embodiment Two

[0040] The difference between Embodiment Two and the embodiment is only that it further includes a vision detection system. The vision detection system is installed in the box body 5, and its working principle is to perform omnidirectional image acquisition of the small parts through a high-resolution camera, and then transmit the acquired image data to the data acquisition and analysis system. This system uses advanced image recognition algorithms to accurately detect the appearance dimensions and surface defects of the small parts. Its core advantage is that it can accurately identify the defective parts with a size deviation exceeding 0.05 mm or a surface scratch depth greater than 0.03 mm at a speed of processing one hundred parts per second, and quickly feedback the information of the unqualified products to the control assembly 4. After receiving the signal, the control assembly 4 will instruct the clamping assembly 1 to transfer the unqualified small parts to a dedicated waste recycling area instead of continuing to participate in subsequent cleaning, weighing and other processes, thereby avoiding resource waste and loss of production efficiency at the source.

[0041] In addition to processing visual inspection data, the data acquisition and analysis system also realizes data interaction with key components such as the weighing component 7, the cleaning component 6, and the moving component 2. It can record production data such as the weight of each small part, the cleaning duration, and the moving path in real time, and use big data analysis technology to deeply mine this data. For example, by analyzing the weight distribution curves of small parts in different batches, the system can predict fluctuations in raw material supply in advance, providing a scientific basis for production scheduling; at the same time, by statistically analyzing the working data of the cleaning component 6, it can also intelligently evaluate the cleaning efficiency. When it detects a decrease in the cleaning effect, it automatically adjusts the air flow intensity of the compressed air or the working frequency of the cleaning head 27 to ensure that the cleaning quality always remains in the best state. Embodiment III

[0042] The difference between Embodiment III and Embodiment I and Embodiment II is only that a vibrating screen device added to the conveyor belt component 3 adopts a multi-layer screen structure, and the screen aperture is carefully designed according to the specifications of the small parts. When the small parts are conveyed from the upstream process to the vibrating screen device, the device screens at a vibration frequency of 300 times per minute, effectively intercepting parts with too small size or irregular shape and preventing them from entering the subsequent automated processing process. This not only reduces the burden on the visual inspection system but also further improves the overall production efficiency, ensuring that the small parts entering the automated processing link have high quality uniformity.

[0043] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
