Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machining equipment, and in particular to a feeding mechanism and loading / unloading device. Background Technology
[0002] In traditional manual production lines, various processing equipment needs to be arranged on both sides of the main production line. Operators need to pick up the carriers and products from the production line and place them on the processing platform of the equipment for processing. After processing, the carriers and products need to be placed back on the production line to continue to the next station. With the increase in labor costs, the labor costs generated by using traditional manual operations account for an increasingly larger proportion of the production process. At the same time, the existing loading and unloading devices do not clearly define the product feeding and unloading stations, which makes designers insensitive to the spatial layout of the scanning mechanism within the frame, or the outer shell of the frame components cannot accurately reserve opening structures for product placement, so most or all of the product rack perimeter can only be set as an open structure, making the outer shell unable to fully protect the product. Summary of the Invention
[0003] This utility model provides a feeding mechanism and a loading / unloading device, which aims to solve at least one of the technical problems existing in the prior art.
[0004] According to a first aspect of the present invention, the present invention provides a feeding mechanism for use in a loading and unloading device. The feeding mechanism includes a feeding guide rail assembly, a material tray limiting assembly, and a feeding platform for placing a fixed product into a placement clamp. The feeding platform is slidably mounted on the product rack of the loading and unloading device via the feeding guide rail assembly. The material tray limiting assembly is disposed at the bottom of the feeding platform and is used to cooperate with the feeding guide rail assembly to limit the movement position of the feeding platform.
[0005] The tray limiting assembly includes a control lever, a drive plate, and a tray limiting member. The drive plate has drive grooves on both sides that are inclined inward. The control lever is movably mounted on the feeding platform and is connected to the drive plate. One end of the tray limiting member is slidably connected to the drive groove, and the other end of the tray limiting member is used to cooperate with the feeding guide rail assembly, so that the control lever can control the tray limiting member to extend or retract from the feeding platform through the drive groove, thereby limiting the movement position of the feeding platform or releasing the restriction on the feeding platform.
[0006] According to a second aspect of the present invention, the present invention also provides a loading and unloading device, including the above-mentioned unloading mechanism.
[0007] The technical solution provided in this application can include the following beneficial effects: This application designs a feeding mechanism and a loading / unloading device, which can realize the loading and unloading of products on the product rack through the feeding mechanism, so as to reduce the number and size of the openings in the shell of the rack assembly. It not only enables loading and unloading at the same location, but also allows most of the product rack structure to be fully protected by the shell. Simultaneously, the feeding platform of the feeding mechanism is slidably mounted on the product rack through a feeding guide rail assembly, so that it can extend or retract from the product rack to facilitate the placement of products into the feeding platform. Furthermore, this application also uses a tray limiting assembly to position the moving part of the feeding platform, ensuring the stability of the product after it is placed on the feeding platform, significantly reducing the operational risks of the loading / unloading device when transferring products.

Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0033] like Figures 1 to 15As shown, this application provides a loading and unloading device, including an actuator 200, a product rack 100, and a frame assembly 300. The product rack 100 is used to place products so that the actuator 200 can grab products at corresponding positions on the product rack 100 according to processing requirements, thereby completing the loading and unloading operation. The product rack 100 can also buffer products, reducing intermittent replenishment time and effectively saving labor. The frame assembly 300 covers the actuator 200 and the product rack 100, ensuring the compactness and safety of the loading and unloading device. It prevents the actuator 200 and the product rack 100 from being exposed outside the frame assembly 300, thus protecting them whether the loading and unloading device is stopped or in operation. This solves the safety hazards caused by the exposed actuator 200 and the product rack 100 during operation and also effectively prevents the products on the actuator 200 and the product rack 100 from direct contact with moisture in the air, affecting their service life, improving safety, and ensuring the overall appearance and structure of the loading and unloading device.
[0034] In one optional embodiment, the product rack 100 includes a main frame 103, a rotating tray mechanism 102, and a fixed tray mechanism. The rotating tray mechanism 102 and the fixed tray mechanism are disposed on both sides of the main frame 103, and the actuator 200 is disposed between the rotating tray mechanism 102 and the fixed tray mechanism. This facilitates the transfer of products from the rotating tray mechanism 102 and the fixed tray mechanism to the machining center for processing, or the transfer of products processed at the machining center back to the rotating tray mechanism 102 and the fixed tray mechanism, thereby achieving automated loading and unloading and reducing manual labor intensity. The rotating tray mechanism 102 is rotatably connected to the main frame 103 to facilitate the maintenance of the loading and unloading device and effectively reduce manufacturing and maintenance costs.
[0035] In an optional embodiment, the fixed tray mechanism includes a first tray 101, and the rotating tray mechanism 102 includes a second tray 1021. The first tray 101 and the second tray 1021 are arranged on both sides of the main frame 103 so that materials can be fed through the hopper of the first tray 101 and the second tray 1021. This results in a large number of products being buffered, a long intermittent replenishment time, and effectively saves labor.
[0036] In an optional embodiment, the actuator 200 includes a rotating component 201, a lifting component 202, and a telescopic component 203. The lifting component 202 is mounted on the main frame 103 via the rotating component 201 and is located between the first material rack 101 and the second material rack 1021. The telescopic component 203 is mounted on the lifting component 202, enabling the lifting component 202 to control the telescopic component 203 to move up and down, thereby enabling the telescopic component 203 to load and unload materials in the height direction of the first material rack 101 and the second material rack 1021. At the same time, the telescopic characteristics of the telescopic component 203 can be used to transfer products on the first material rack 101 and the second material rack 1021 to the processing center, or to transfer products that have been processed on the processing center back to the first material rack 101 and the second material rack 1021. It can even transfer products between the first material rack 101 and the second material rack 1021, thereby realizing the transfer of products between the processing center, the first material rack 101, and the second material rack 1021.
[0037] In an optional embodiment, the loading and unloading device further includes a feeding mechanism 104 that can extend outward from the frame assembly 300. The frame assembly 300 has a receiving chamber and an opening structure 301 located on one side of the receiving chamber. The actuator 200 and the product rack 100 are both disposed in the receiving chamber. The feeding mechanism 104 is disposed on the product rack 100 and corresponds to the position of the opening structure 301, so that the feeding mechanism 104 can extend from the opening structure 301, so that the operator or other conveying mechanism can put the product into the feeding mechanism 104 from the opening structure 301. Then the feeding mechanism 104 can transfer the product to the product rack 100, and then the actuator 200 can transfer the product on the feeding mechanism 104 to the processing center or other positions of the product rack 100.
[0038] In an optional embodiment, the frame assembly 300 has an open structure 302, and a display panel 303 is installed on one side of the frame assembly 300 to realize the display and / or interactive operation functions of the loading and unloading device, so that the operator can understand the operation status of the loading and unloading device in real time. The open structure 302 and the open structure 301 are located on adjacent sides of the frame assembly 300, respectively. The position of the open structure 302 corresponds to the position of the machining center, so that the telescopic assembly 203 can transfer the products on the first rack 101 and the second rack 1021 to the machining center, or transfer the products processed by the machining center to the first rack 101 and the second rack 1021. The open structure 301 is equipped with a door panel, which is used to open or close to cover the open structure 301. This can prevent the loading and unloading device from being exposed to the air when the machine is stopped, thus affecting the service life of the actuator 200, the first rack 101 and the second rack 1021, etc., and thus protecting the actuator 200, the first rack 101 and the second rack 1021.
[0039] After adopting the above technical solution, this application sets the opening structure 301 as the product feeding station and product removal station of the loading and unloading device, while the open structure 302 is connected to the machining center and will not be open to the outside. That is, the frame assembly 300 of the loading and unloading device has only one opening structure 301 open to the outside. The opening structure 301 is mainly used for loading and unloading products, thereby reducing the number and size of openings in the shell of the frame assembly 300. It can not only realize loading and unloading at the same position, but also allow most of the structure of the product rack 100 to be covered by the shell for comprehensive protection. Meanwhile, this application has planned the layout space of the product feeding station, product removal station, first material rack 101, second material rack 1021, actuator 200 and open structure 302, as well as the movement route of actuator 200 and unloading mechanism 104. This saves the layout space inside the frame assembly 300, ensures the compactness and safety of the loading and unloading device, and avoids the actuator 200 and product rack 100 being exposed outside the frame assembly 300. In this way, the loading and unloading device can be protected whether it is stopped or working, which solves the safety hazards caused by the exposed actuator 200 and product rack 100 during operation. It also effectively avoids the actuator 200 and product rack 100 from direct contact with moisture in the air, which affects their service life, improves the safety of use, and ensures the overall appearance and structure of the loading and unloading device.
[0040] In an optional embodiment, the first rack 101 includes a first frame 1011 and a first placement plate 1012. The first placement plate 1012 is spaced apart along the height direction of the first frame 1011 to form a plurality of first receiving channels. The feeding mechanism 104 is installed in one of the first receiving channels so that the telescopic assembly 203 can transfer the products placed from the feeding mechanism 104 to the second rack 1021, the machining center, or other first receiving channels of the first rack 101. This results in high utilization, simplifies the product rack 100, and effectively reduces manufacturing and maintenance costs.
[0041] In an optional embodiment, the loading and unloading device further includes a placement clamp 400 for fixing the product. The first placement plate 1012 is provided with a plurality of first limiting grooves, and the placement clamp 400 is provided with a plurality of limiting posts 4011. The positions of the limiting posts 4011 correspond to the positions of the first limiting grooves, so that the placement clamp 400 can be placed on the first material rack 101, and the position of the placement clamp 400 in the first receiving channel can be restricted by the cooperation of the limiting posts 4011 and the first limiting grooves.
[0042] In an optional embodiment, the placement fixture 400 includes a placement seat 401 and a clamping seat 402 for clamping the product. The clamping seat 402 is smaller than the placement seat 401 and is disposed on the placement seat 401. A limiting post 4011 is disposed on the side of the placement seat 401 away from the clamping seat 402, so that the placement seat 401 can accommodate clamping seats 402 of different sizes.
[0043] In an optional embodiment, the loading and unloading device further includes a scanning mechanism. The placement fixture 400 is equipped with an electronic tag. During the process of the actuator 200 transferring the products on the first rack 101 and the second rack 1021 to the processing center, the products pass through the corresponding position of the scanning mechanism, so that the scanning mechanism can scan the electronic tag on the placement fixture 400. Then, the information of the product or the subcontracted parts is recorded and stored in the electronic terminal of the loading and unloading device, so that the products or subcontracted products on the entire product rack 100 can be managed or processed through the electronic terminal. The structure is simple yet practical, and it greatly improves production efficiency and reduces labor costs.
[0044] In one optional embodiment, the rotating assembly 201 includes a servo motor, a rotating platform, a servo encoder, and a servo driver. The servo motor drives the rotating platform to rotate, and the servo encoder detects and encodes the rotational position of the servo motor and feeds it back to the servo driver, so that the servo motor can drive the rotating assembly 201 to rotate to any position angle of the main frame 103, so as to transfer each product on the first rack 101 and the second rack 1021 to the processing center, or transfer the products on the processing center to each position of the first rack 101 and the second rack 1021.
[0045] In one optional embodiment, the lifting assembly 202 includes a lifting frame 2021, a lifting drive motor 2022, and a lifting screw assembly. The lifting screw assembly is arranged along the height direction of the lifting frame 2021. The lifting frame 2021 is fixed on the rotating platform. The lifting drive motor 2022 is installed on the side of the lifting frame 2021 away from the rotating platform and is used to drive the telescopic assembly 203 to move up and down, and to ensure the positional accuracy of the telescopic assembly 203 when it moves up and down in a straight line.
[0046] In an optional embodiment, the telescopic assembly 203 includes a first telescopic frame 2031, a second telescopic frame 2032, a third telescopic frame 2033, and a mechanical claw 2034. The first telescopic frame 2031 and the second telescopic frame 2032 are connected by a telescopic screw assembly 2035, and the second telescopic frame 2032 and the third telescopic frame 2033 are connected by a belt drive assembly 2036. The mechanical claw 2034 is mounted on the third telescopic frame 2033. The first telescopic frame 2031 is connected to the lifting screw assembly to achieve the purpose of suspension telescopic movement. At the same time, the first telescopic frame 2031, the second telescopic frame 2032, and the third telescopic frame 2033 can realize a multi-layer telescopic structure of the telescopic assembly 203, increasing the telescopic stroke of the telescopic assembly 203, so that the maximum effective stroke of the telescopic assembly 203 along its length direction is 100 mm.
[0047] In one optional embodiment, the main frame 103 has a first mounting boss 1031 and a second mounting boss 1032 on both sides. The rotating assembly 201 is disposed between the first mounting boss 1031 and the second mounting boss 1032. The first material rack 101 is fixed on the first mounting boss 1031, and the second material rack 1021 is rotatably mounted on the second mounting boss 1032. The height of the rotating platform is lower than the height of the first mounting boss 1031 and the second mounting boss 1032, ensuring that the lifting assembly 202 can control the positional accuracy of the telescopic assembly 203 relative to the first material rack 101 and the second material rack 1021 during linear vertical movement.
[0048] In an optional embodiment, the rotating tray mechanism 102 includes a turntable drive assembly 1024. The second material rack 1021 is rotatably mounted on one side of the main frame 103 via the turntable drive assembly 1024. The turntable drive assembly 1024 drives the second material rack 1021 to rotate relative to the main frame 103 within a range of no more than 120 degrees, so that operators can enter the inside of the main frame 103 for maintenance after rotating the second material rack 1021, reducing the maintenance cost of the loading and unloading device and improving the safety performance of the loading and unloading device. The turntable drive assembly 1024 is disposed between the second material rack 1021 and the main frame 103.
[0049] In an optional embodiment, the rotating tray mechanism 102 further includes a turntable limiting component 1023 and a turntable positioning component 1022. The turntable limiting component 1023 is disposed on the outer side of the main frame 103, and the turntable positioning component 1022 is disposed on the inner side of the main frame 103. The line connecting the turntable limiting component 1023 and the turntable positioning component 1022 passes through the rotation center of the second material rack 1021. This not only ensures that the rotation range does not exceed the set value, avoiding interference with the structure of the main frame 103 and achieving safe and reliable limited-angle rotation, but also ensures that the force on the second material rack 1021 is symmetrical, avoiding bearing wear between the second material rack 1021, the turntable drive component 1024, and the main frame 103 due to uneven loading. The turntable positioning component 1022 includes, but is not limited to, a Hall sensor or a photoelectric through-beam switch.
[0050] In an optional embodiment, the second rack 1021 includes a second frame 10211 and a concave second placement plate 10212. The second placement plate 10212 is spaced apart along the height direction of the second frame 10211 to form a plurality of second receiving channels. Each second receiving channel has two second product placement areas for placing the placement fixture 400 that fixes the product. The concave surface of the second placement plate 10212 has an inclination angle in the range of 5 degrees to 10 degrees to utilize gravity for self-centering and reduce the positioning error of the placement fixture 400.
[0051] In an optional embodiment, the central axes of the two second product placement areas extend toward the inside of the main frame 103 and intersect at the center of the actuator 200 of the loading / unloading device, so as to ensure, through precise spatial geometric alignment, that the actuator 200 can transfer the placement fixture 400 to each second product placement area. Similarly, the first rack 101 also has the same number of first product placement areas as the second product placement areas.
[0052] In one optional embodiment, the second product placement area is provided with a plurality of second limiting grooves, and the position of the limiting post 4011 on the placement fixture 400 corresponds to the position of the second limiting groove, so that the placement fixture 400 is placed on the second material rack 1021 and the position of the placement fixture 400 in the second receiving channel of the second material rack 1021 can be restricted by the cooperation of the limiting post 4011 and the second limiting groove.
[0053] In an optional embodiment, a second product detection component 1025 is provided on the second product placement area. The second product detection component 1025 is used to detect whether the placement fixture 400 exists on the second product placement area and / or the placement fixture 400 is in place, so that the actuator 200 can stably transfer the placement fixture 400 on the second product placement area according to the detection status of the second product detection component 1025, thereby improving work efficiency and accuracy. Similarly, the first material rack 101 is also provided with a first product detection component 1013 in the first product placement area.
[0054] In an optional embodiment, the turntable drive assembly 1024 includes a turntable drive gear and a rotating tray handle. The rotating tray handle is mounted on the second frame 10211, and the turntable drive gear is positioned between the second frame 10211 and the main frame 103, enabling dual-mode operation of the second material rack 1021 with limited-angle rotation and manual intervention. The rotating tray handle is installed within the projection plane of the center of gravity of the second frame 10211, and its distance from the rotation axis of the second frame 10211 is two-thirds of the rotation radius of the second frame 10211, ensuring balanced manual force application. The turntable drive gear can achieve automatic rotation of the second frame 10211 via a drive motor or other means.
[0055] In an optional embodiment, the feeding mechanism 104 includes a feeding guide rail assembly 1042, a tray limiting assembly 1045, and a feeding platform 1041 for placing a fixed product into a placement clamp 400. The feeding platform 1041 is slidably mounted on the product rack 100 of the loading and unloading device via the feeding guide rail assembly 1042. The tray limiting assembly 1045 is located at the bottom of the feeding platform 1041 and is used to cooperate with the feeding guide rail assembly 1042 to limit the movement of the feeding platform 1041, ensuring the stability of the product after it is placed on the feeding platform 1041, and greatly reducing the operational risks of the loading and unloading device when transferring products. The material feeding platform 1041 is the main load-bearing component used to fix and place the clamp 400; the material feeding guide rail assembly 1042 is a sliding guide mechanism, including but not limited to linear guide rails, sliders or rollers, so as to realize the linear movement of the material feeding platform 1041 on the product rack 100; the material tray limiting assembly 1045 is mainly a mechanical limiter to restrict the movement position of the material feeding platform 1041.
[0056] In an optional embodiment, the tray limiting assembly 1045 includes a control rod 10451, a drive plate 10452, and a tray limiting member 10453. The drive plate 10452 has inwardly inclined drive grooves on both sides. The control rod 10451 is movably mounted on the feeding platform 1041 and is connected to the drive plate 10452. One end of the tray limiting member 10453 is slidably connected to the drive groove, and the other end of the tray limiting member 10453 is used to cooperate with the feeding guide rail assembly 1042. This allows the control rod 10451 to control the tray limiting member 10453 to extend or retract from the feeding platform 1041 via the drive groove, thereby limiting the movement of the feeding platform 1041 or releasing the restriction on the feeding platform 1041. The inclination angle of the drive groove is within the range of 30 to 45 degrees to ensure efficient force transmission and avoid excessively small angles that would result in excessive mechanical gain. Similarly, the drive groove can also be equipped with balls or bushings to reduce friction.
[0057] In an optional embodiment, the feeding platform 1041 includes a tray frame 1041a and a feeding tray 1041b with a tray groove. The feeding guide assembly 1042 and the tray limiting assembly 1045 are disposed on the back of the tray frame 1041a, and the feeding tray 1041b is mounted on the front of the tray frame 1041a. The tray groove is used to cooperate with the limiting post 4011 of the fixture 400 to limit the position of the fixture 400, thereby realizing the functional zoning and modular assembly function of the feeding platform 1041.
