Description

Technical Field

[0001] This application relates to the technical field of screw extraction equipment, and in particular to an automatic screw rotation extraction device. Background Technology

[0002] Currently, in the field of automated production and assembly, to ensure the stability of products during processing or transportation, tooling plates (or fixtures) are typically used to support the products, and process screws are used to temporarily fix product components to the tooling plates (at this time, the tooling plates are usually equipped with screw bases for the process screws to be installed). After the products have completed a series of processing steps, finished assembly, and come off the production line, the empty tooling plates are returned to the initial loading station via a return line. In order to assemble the next round of products, the remaining process screws must be removed from the tooling bases during the tooling return process so that the screws can be reused to fix new products later.

[0003] In related technologies, the removal of the process screw mainly relies on manual operation by the operator. The typical workflow is as follows: the operator is stationed at the recycle station, holding a socket screwdriver or ordinary electric screwdriver, visually judging the position of the screw, aligning the tool head with the screw head, and then manually applying force to rotate and gradually unscrew the process screw from the base. Finally, the removed screw is placed into the designated recycling bin by hand.

[0004] Regarding the aforementioned technologies: manual operation is inefficient and unstable. Differences in operator skill and fatigue from prolonged work directly affect the extraction speed, easily causing fluctuations in production rhythm. In some cases, delayed operation can lead to tooling accumulation on the return line, forcing the entire production line to stop. Secondly, relying solely on manual alignment and force is prone to errors such as misalignment causing screw head stripping or the screw slipping and falling into tooling gaps during extraction, severely impacting product quality and equipment operation. Therefore, there is an urgent need for a device that can automatically, stably, and efficiently extract process screws. Summary of the Invention

[0005] To address the issues of low efficiency, high risk, and unstable quality in process screw removal, this application provides an automatic screw rotation removal device.

[0006] This application provides an automatic screw rotation and extraction device, which adopts the following technical solution: An automatic screw rotation extraction device includes: main body; A rotary material handling module includes a drive component, a clamping component, and a positioning component. The drive component is disposed on the main body, the clamping component is connected to the drive component and is used to clamp a screw, and the positioning component is located below the drive component and is used to position the screw. A detection module is disposed on the main body and close to the clamping assembly, and the detection module is used to detect the position of the screw.

[0007] By adopting the above technical solution, the drive component provides power for the screw's rotation and extraction, the clamping component firmly clamps the screw, and the positioning component positions the screw to ensure accurate positioning during extraction, reducing the risk of extraction failure. The detection module, located close to the clamping component, accurately detects the screw's position, providing precise information for subsequent extraction operations. This allows the rotating extraction module to act more precisely on the screw, thereby achieving automated and stable screw extraction. This effectively avoids the inefficiency of traditional manual extraction, the risk of frequent extraction failures due to varying operator familiarity, or excessive production line dwell time caused by untimely extraction, thus improving work efficiency and product quality.

[0008] Optionally, the positioning component includes a mounting base, a flip plate, and a flipping drive. The mounting base is located below the clamping component. The flip plate is rotatably connected to the mounting base. The flipping drive is disposed on the mounting base and connected to the flip plate. A guide groove is provided on the flip plate, and the screw can pass through the guide groove.

[0009] By adopting the above technical solution, the mounting base is located below the clamping assembly, providing a stable support foundation for the entire positioning structure. The flip plate is rotatably connected to the mounting base and driven by the flipping drive component, allowing the flip plate to rotate flexibly. The guide groove on the flip plate allows the screw to pass through it. When the screw needs to be positioned, the flipping drive component drives the flip plate to rotate to the appropriate position, and the guide groove accurately guides the screw, ensuring that the screw is in the correct position. This facilitates precise clamping of the screw by the subsequent clamping assembly, thereby improving the accuracy and stability of the screw removal operation, helping to avoid material removal failure due to screw position deviation, reducing the risk of material removal failure, and also helping to improve the efficiency of the entire screw removal process.

[0010] Optionally, the main body is provided with an adsorption component, the driving component includes a rotary driving element and a rotary shaft, the rotary driving element is disposed on the main body, the rotary shaft is connected to the output end of the rotary driving element, the adsorption component is connected to the rotary shaft, the clamping component is disposed on the rotary shaft, the clamping component is provided with a clearance groove, the screw can pass through the clearance groove and connect to the adsorption component, and the adsorption component is used to adsorb the screw.

[0011] By adopting the above technical solution, the rotary drive component drives the rotary shaft to rotate, and the rotary shaft drives the clamping component and the adsorption component to move together. The clearance groove on the clamping component allows the screw to pass through and connect with the adsorption component, which can adsorb the screw. Thus, when the rotary shaft rotates, it can ensure that the screw is stably driven to rotate, realizing automatic rotation and removal of the screw. This helps to avoid the screw shaking or falling off during rotation, improving the stability and reliability of screw removal. It effectively solves the problems of low efficiency and easy error when manually removing screws in the traditional way, and improves work efficiency and product quality.

[0012] Optionally, the adsorption assembly includes a flexible disk, a vacuum pipeline, and a vacuum generating unit. The flexible disk is disposed on the rotating shaft and close to the clearance groove. The flexible disk has several through holes. The vacuum pipeline is coaxially disposed inside the rotating shaft and communicates with several of the through holes. The vacuum generating unit is disposed on the main body and communicates with the vacuum pipeline.

[0013] By adopting the above technical solution, the flexible disk is positioned close to the clearance groove and has several through holes. The vacuum pipeline is coaxially arranged inside the rotating shaft and connected to the through holes. The vacuum generating unit is connected to the vacuum pipeline. When the screw needs to be removed, the vacuum generating unit works, causing the vacuum pipeline to generate negative pressure. This negative pressure then creates an adsorption force on the screw through the through holes on the flexible disk, thus achieving the adsorption and fixation of the screw. This effectively prevents the screw from shaking or falling off during the removal process, improving the stability and reliability of screw removal. In conjunction with the drive assembly and clamping assembly, the automatic rotation and removal of the screw can be completed more effectively, improving work efficiency.

[0014] Optionally, the main body is provided with a guide component, which surrounds the clamping component. The detection module is located beside the guide component and can detect the screw through the guide component.

[0015] By adopting the above technical solution, the guide component plays a guiding and protective role. On the one hand, it provides a suitable detection path and environment for the detection module, enabling the detection module to obtain relevant information about the screw more accurately. On the other hand, the surrounding clamping component can prevent external factors from interfering with the detection process. The detection module is located next to the guide component. By detecting the screw through the guide component, the accuracy and stability of the detection can be improved. This, in turn, helps the subsequent rotary material handling module to more accurately position and clamp the screw, achieving efficient and automatic rotary extraction of the screw.

[0016] Optionally, the guiding assembly includes a guide sleeve disposed on the main body, the clamping assembly is disposed inside the guide sleeve and spaced apart from the inner wall of the guide sleeve, a transparent window is embedded in the guide sleeve, and the detection module includes a camera and a reflecting prism, the camera is disposed on the main body and close to the transparent window, the reflecting prism is embedded in the transparent window, and the reflecting prism is used to refract the image information of the screw to the camera.

[0017] By adopting the above technical solution, the guide sleeve is set on the main body, and the clamping component is placed inside it and spaced apart from the inner wall, providing a stable spatial environment for the removal of the screw, thereby helping to avoid external interference. The transparent window embedded in the guide sleeve ensures that light can pass through, creating conditions for the reflecting prism to refract the image information of the screw. The camera is set close to the transparent window, and the reflecting prism is embedded in the transparent window, constructing a complete image refraction and reception system. This allows the image information of the screw to be smoothly refracted to the camera through the reflecting prism, enabling the device to accurately obtain the position information of the screw. This provides a reliable basis for the subsequent precise clamping and removal of the screw, enhancing the accuracy and stability of the device's operation.

[0018] Optionally, the top end of the guide sleeve is provided with an annular light source, which is used to couple light into the cylinder wall of the guide sleeve for conductive illumination.

[0019] By adopting the above technical solution, the ring light source is set at the top of the guide sleeve, which can couple light into the cylinder wall of the guide sleeve for conduction and illumination. This allows the light to be evenly distributed inside the guide sleeve, providing clear and uniform lighting conditions for the detection module (such as a camera). This enables the detection module to acquire image information of the screw more accurately, thereby improving the detection accuracy of the screw position. This provides a reliable basis for the subsequent rotary material handling module to accurately clamp and rotate the screw, ensuring the efficient and stable operation of the entire automatic screw rotation and extraction device.

[0020] Optionally, an air curtain assembly is provided at one end of the guide sleeve away from the main body. The air curtain assembly is arranged around the axis of the guide sleeve and is used to form an air curtain.

[0021] By adopting the above technical solution, the air curtain assembly is set around the axis of the guide sleeve and can form an air curtain. When the device is working, the air curtain can actively blow away the oil and debris on the surface of the workpiece, creating a clean environment for the subsequent detection module to detect the screw position and the rotary material handling module to remove the screw. This helps to avoid oil and debris affecting the screw's positioning, clamping and rotary removal operations, ensuring the stability and accuracy of the screw removal process and improving the efficiency and success rate of the screw removal operation.

[0022] Optionally, the guide sleeve has a chamber located below the transparent window. The air curtain assembly includes an air source and multiple nozzles. The air source is disposed on the main body and communicates with the chamber. The multiple nozzles are disposed around the axis of the guide sleeve at the end of the guide sleeve away from the main body, and are oriented towards the axis of the guide sleeve and communicate with the chambers respectively.

[0023] By adopting the above technical solution, the gas source is connected to the chamber, allowing gas to be delivered into the chamber. Multiple nozzles, arranged around the axis of the guide sleeve at the end of the guide sleeve away from the main body and facing the axis of the guide sleeve, are connected to the chamber, enabling the gas in the chamber to be ejected from these nozzles to form an air curtain. This air curtain can actively blow away oil and debris on the surface of the workpiece during device operation, creating a clean environment for visual alignment. This allows the detection module to obtain the position information of the screw more clearly and accurately, thereby improving the positioning accuracy and stability of the screw removal process. It also helps with subsequent screw clamping and unscrewing operations, improving the working efficiency and reliability of the entire automatic screw rotation and removal device.

[0024] Optionally, the guide sleeve is tapered at the end away from the main body, and the nozzle is inclined at the end away from the clamping assembly.

[0025] By adopting the above technical solution, the end of the guide sleeve furthest from the main body is tapered, and the nozzle is tilted towards the end furthest from the clamping assembly. This allows the air curtain formed by the air curtain assembly to better cover the area around the screw. The tapered end of the guide sleeve can guide the airflow diffusion, and the tilted nozzle can make the airflow direction more conducive to blowing away oil and debris on the workpiece surface. This creates a cleaner environment for visual alignment before the screw is removed, improves the accuracy of the detection module in detecting the screw position, ensures that the subsequent clamping assembly can accurately clamp the screw, and improves the efficiency and success rate of automatic screw rotation and removal.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Automated equipment is used to replace manual operation. Stable and efficient screw removal operation is achieved through rotating material handling module and detection module, reducing efficiency fluctuations caused by differences in operator skill and improving removal efficiency; 2. By using the detection module to position the screw and the positioning component to work together with the clamping and adsorption components, the screw is ensured not to shift or slip during the removal process, thus avoiding material removal failure due to operational errors and reducing the risk of material removal failure. 3. Through the cooperation of the guiding components, detection modules and air curtain components, the recognition accuracy in complex working conditions (such as oily environments) is further improved, effectively shortening the production line waiting time, reducing production line downtime, and improving the overall production cycle and product quality consistency.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an automatic screw rotation extraction device.

[0035] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1: Refer to Figure 1An automatic screw rotation and extraction device includes a main body 1, a rotation and extraction module 2, and a detection module 3. The rotation and extraction module 2 and the detection module 3 are respectively mounted on the main body 1. The rotation and extraction module 2 clamps and rotates the screw 4 to extract it, while the detection module 3 detects the position of the screw 4, providing a basis for the accurate operation of the rotation and extraction module 2. This enables the device to automatically and stably extract the screw 4, avoiding the problems of low efficiency and unstable quality associated with manual operation. It should be noted that in this embodiment, the screw 4 is mounted on a screw base 5.

[0037] The main body 1 is a robot, with a rotary material handling module 2 and a detection module 3 installed at the end of the robot. This allows the main body 1 to move the rotary material handling module 2 and the detection module 3, thereby rotating and removing the screw 4. In other embodiments, the main body 1 may also employ a three-axis motion mechanism to drive the rotary material handling module 2 and the detection module 3.

[0038] The rotary material handling module 2 includes a drive assembly 21, a clamping assembly 22, and a positioning assembly 23. The drive assembly 21 is mounted on the main body 1, the clamping assembly 22 is connected to the drive assembly 21, and the positioning assembly 23 is located below the drive assembly 21.

[0039] The positioning assembly 23 includes a mounting base 231, a flip plate 232, and a flipping drive component 233. The mounting base 231 is located below the clamping assembly 22. The flip plate 232 is rotatably connected to the mounting base 231, and the flipping drive component 233 is mounted on the mounting base 231 and connected to the flip plate 232. The flip plate 232 has a guide groove 2321. In this embodiment, the flipping drive component 233 is a motor, so as to drive the flip plate 232 to rotate.

[0040] It should be noted that in this embodiment, the mounting base 231 is located on the side of the production line. After the product is assembled and removed from the production line after a series of processing steps, the screw base 5 will be transported by the production line to a position close to the mounting base 231. The flipping drive 233 drives the flipping plate 232 to rotate so that the flipping plate 232 moves above the screw 4. At this time, the screw 4 is inserted into the guide groove 2321 so that the flipping plate 232 can be used to position and guide the screw 4.

[0041] The drive assembly 21 includes a rotary drive component 211 and a rotary shaft 212. The rotary drive component 211 is mounted on the main body 1, and one end of the rotary shaft 212 is connected to the output end of the rotary drive component 211. In this embodiment, the rotary drive component 211 is a servo motor, so that the rotary drive component 211 can drive the rotary shaft 212 to rotate when it is working.

[0042] The clamping assembly 22 is connected to the end of the rotating shaft 212 away from the rotating drive member 211. In this embodiment, the clamping assembly 22 is a duckbill clamp to facilitate clamping the screw 4.

[0043] The detection module 3 includes a camera 31, which is mounted on the main body 1 and located beside the clamping assembly 22. In this embodiment, the camera 31 is a miniature industrial camera to facilitate the detection of the position of the screw 4, providing data support for the accurate operation of the device.

[0044] The implementation principle of the automatic screw rotation and extraction device in this embodiment is as follows: When the screw 4 is conveyed by the production line to a position near the mounting base 231, the flipping drive 233 drives the flipping plate 232 to rotate, so that the flipping plate 232 moves above the screw 4 and the screw 4 passes through the guide groove 2321. At this time, the robot drives the rotating material handling module 2 and the detection module 3 to move above the screw 4. The camera 31 captures an image of the screw 4 and identifies the position and size of the screw 4 head. The robot adjusts its posture according to the coordinates fed back by the camera 31, so that the clamping component 22 is aligned with the screw 4. The robot descends, and the clamping component 22 clamps the screw 4. Then the rotating drive 211 is activated, driving the clamping component 22 to rotate through the rotating shaft 212, thereby driving the screw 4 to rotate. At the same time, the robot lifts up, thus facilitating the complete unscrewing of the screw 4.

[0045] After screw 4 is removed, the robot moves away, and then the flip drive 233 drives the flip plate 232 to rotate and reset, making room for the arrival of the next screw 4 and avoiding interference.

[0046] Example 2: Refer to Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the adsorption component 11 and the guide component 12 are respectively arranged on the main body 1, and the detection module 3 includes a reflective prism 32.

[0047] Reference Figure 3 and Figure 4 In this embodiment, the clamping assembly 22 adopts a three-jaw clamping mechanism, and the clamping assembly 22 is provided with a clearance groove 221. The clearance groove 221 is located at the center of the three jaws so that the screw 4 can pass through the clearance groove 221. The rotary drive component 211 is a hollow servo motor to allow cables and hoses to pass through.

[0048] Reference Figure 3 and Figure 5The adsorption assembly 11 includes a flexible disk 111, a vacuum pipeline 112, and a vacuum generating unit 113. The flexible disk 111 is disposed on the rotating shaft 212 and close to the clearance groove 221, and the screw 4 can pass through the clearance groove 221 and fit against the flexible disk 111. In this embodiment, the flexible disk 111 can be made of a material with a certain degree of elasticity, such as rubber, to better fit the surface of the screw 4.

[0049] The flexible disk 111 has several through holes 1111. Vacuum lines 112 are coaxially arranged within the rotating shaft 212 and communicate with the through holes 1111. A vacuum generating unit 113 is mounted on the main body 1 and communicates with the vacuum lines 112 via a rotary airtight connector. In this embodiment, the vacuum generating unit 113 is a vacuum generator. In other embodiments, the vacuum generating unit 113 may also be a vacuum pump.

[0050] When the vacuum generating unit 113 is working, the vacuum pipeline 112 generates suction through the through hole 1111 on the flexible disk 111, thereby adsorbing the screw 4, which further enhances the fixing effect of the screw 4. In conjunction with the clamping assembly 22, it achieves double fixing of the screw 4, which helps to reduce the possibility of the screw 4 falling due to unstable clamping of the clamping assembly 22, and improves the safety of screw 4 removal and transportation to a certain extent.

[0051] In this embodiment, a pressure sensor is provided inside the flexible disk 111 to detect the contact pressure between the screw 4 and the flexible disk 111, thereby facilitating the detection of whether the screw 4 has detached from the flexible disk 111.

[0052] Reference Figure 2 and Figure 3 The guide assembly 12 includes a guide sleeve 121, which is disposed on the main body 1. The clamping assembly 22 is disposed inside the guide sleeve 121 and spaced apart from the inner wall of the guide sleeve 121. In this embodiment, the flexible disk 111 (refer to...) Figure 4 It is also set inside the guide sleeve 121.

[0053] Reference Figure 3 A transparent window 122 is embedded in the guide sleeve 121. The camera 31 is positioned close to the transparent window 122. A reflecting prism 32 is embedded in the transparent window 122. The reflecting prism 32 is used to refract the image information of the screw 4 to the camera 31.

[0054] A ring light source 123 is provided at the top of the guide sleeve 121. In this embodiment, the ring light source 123 is a ring LED light source, which is used to couple light into the guide sleeve 121 for conduction illumination, providing a uniform and shadowless lighting environment for the camera 31, so that the camera 31 can acquire images of the screw 4 more clearly.

[0055] In other embodiments, the guide sleeve 121 may also be made of a transparent material so that the guide sleeve 121 itself can conduct light and further improve the uniformity of illumination.

[0056] When it is necessary to detect the position of screw 4, the robot moves the guide sleeve 121 to above screw 4. At this time, the image light of screw 4 passes through the guide sleeve 121 and is refracted by the reflecting prism 32 before entering the camera 31, which makes it easier for the camera 31 to detect the position of screw 4.

[0057] Reference Figure 2 and Figure 3 A chamber 1211 is provided on the guide sleeve 121, which is located below the transparent window 122. An air curtain assembly 13 is provided at the end of the guide sleeve 121 away from the main body 1. The air curtain assembly 13 includes an air source 131 and multiple nozzles 132. The air source 131 is provided on the main body 1 and communicates with the chamber 1211. The multiple nozzles 132 are arranged around the axis of the guide sleeve 121 at the end of the guide sleeve 121 away from the main body 1, and the multiple nozzles 132 are arranged towards the axis of the guide sleeve 121 and communicate with the chamber 1211 respectively.

[0058] The guide sleeve 121 is tapered at the end away from the main body 1, and the nozzle 132 is inclined at the end away from the clamping assembly 22. In this embodiment, the air source 131 can be an air compressor, so that the air source 131 can supply air to the chamber 1211, so that the gas is ejected from the nozzle 132 through the chamber 1211 to form an annular high-speed air curtain, which actively blows away the oil and debris on the surface of the screw 4, creating a clean environment for the camera 31 to acquire clear images and for subsequent operations.

[0059] The implementation principle of Example 2 is as follows: The robot drives the guide sleeve 121 to approach the screw 4. The ring light source 123 illuminates the workpiece, and the camera 31, through the reflecting prism 32 and the transparent window 122, clearly acquires the coaxial image of the screw 4 without being obstructed by the mechanical structure, thus achieving "visual alignment".

[0060] After alignment, the robot descends. The screw 4 passes through the guide sleeve 121 and the clearance groove 221 in sequence and comes into contact with the flexible disk 111. Then, the clamping assembly 22 clamps the screw 4. The rotary drive 211 drives the clamping assembly 22 and the flexible disk 111 to rotate via the rotating shaft 212, thereby rotating the screw 4 and unscrewing it. During the unscrewing process, the flexible disk 111 continues to absorb, while the air source 131 can selectively supply air to the chamber 1211, causing the gas to be ejected from the nozzle 132 through the chamber 1211, forming a high-speed annular air curtain. This actively blows away oil and debris on the surface of the screw 4, keeping the working area clean and preventing contamination of the equipment or affecting the identification of the next workpiece.

[0061] It should be noted that "visual alignment" in this application refers to the process of acquiring image information of the screw 4 through the camera 31 and processing the information by the control system to accurately guide the rotating material handling module 2 to move to the predetermined operating position.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
