[0031] Next, some embodiments of the present application will be described in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.
[0032] Such as Figures 1 to 15As shown in the figure, the present application provides a loading and unloading device, which includes 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 the products at corresponding positions on the product rack 100 according to the processing requirements, thereby completing the loading and unloading operations of the products and being able to cache the products through the product rack 100. The intermittent replenishment time is long, effectively saving labor. The frame assembly 300 covers the outside of the actuator 200 and the product rack 100, ensuring the compactness and use safety of the loading and unloading device, and preventing the actuator 200 and the product rack 100 from being exposed outside the frame assembly 300. In this way, whether the loading and unloading device is stopped or working, it can be protected, solving the safety hazards existing when the actuator 200 and the product rack 100 are exposed during work, and also effectively preventing the products on the actuator 200 and the product rack 100 from directly contacting the water vapor in the air, affecting their service life, improving the use safety, and ensuring the overall appearance structure of the loading and unloading device.
[0033] In an alternative 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 arranged on both sides of the main frame 103, and the actuator 200 is arranged between the rotating tray mechanism 102 and the fixed tray mechanism to facilitate the transfer of the products on the rotating tray mechanism 102 and the fixed tray mechanism to the machining center for processing or the transfer of the products completed by the machining center back to the rotating tray mechanism 102 and the fixed tray mechanism, realizing automatic loading and unloading and reducing the labor intensity of workers. Among them, 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 the manufacturing and maintenance costs.
[0034] In an alternative embodiment, the fixed tray mechanism includes a first rack 101, and the rotating tray mechanism 102 includes a second rack 1021. The first rack 101 and the second rack 1021 are arranged on both sides of the main frame 103 so as to be able to feed materials in the form of bins of the first rack 101 and the second rack 1021. The number of product caches is large, the intermittent replenishment time is long, and labor is effectively saved.
[0035] In an optional embodiment, the actuating mechanism 200 includes a rotating assembly 201, a lifting assembly 202, and a telescopic assembly 203. The lifting assembly 202 is mounted on the main frame 103 through the rotating assembly 201 and is located between the first rack 101 and the second rack 1021. The telescopic assembly 203 is mounted on the lifting assembly 202, so that the lifting assembly 202 can control the up and down movement of the telescopic assembly 203 to realize the loading and unloading of the telescopic assembly 203 in the height direction of the first rack 101 and the second rack 1021. At the same time, the telescopic characteristics of the telescopic assembly 203 can be utilized to transfer the products on the first rack 101 and the second rack 1021 to the machining center, or transfer the products completed on the machining center back to the first rack 101 and the second rack 1021, and even transfer the products between the first rack 101 and the second rack 1021 to each other, so as to realize the transfer of products among the machining center, the first rack 101 and the second rack 1021.
[0036] In an optional embodiment, the loading and unloading device further includes a blanking mechanism 104 that can extend outside the frame assembly 300. A receiving chamber and an opening structure 301 are provided inside the frame assembly 300. The actuating mechanism 200 and the product rack 100 are both arranged in the receiving chamber. The blanking mechanism 104 is arranged on the product rack 100 and corresponds to the position of the opening structure 301, so that the blanking mechanism 104 can extend out from the opening structure 301, so that an operator or other conveying mechanisms can put products into the blanking mechanism 104 from the opening structure 301. Then, the blanking mechanism 104 can transfer the products to the product rack 100, and further transfer the products on the blanking mechanism 104 to the machining center or other positions of the product rack 100 through the actuating mechanism 200.
[0037] In an optional embodiment, an open structure 302 is provided inside the frame assembly 300. A display panel 303 is installed on one side of the frame assembly 300 to realize the display and / interaction 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. Among them, the open structure 302 and the opening structure 301 are respectively located on adjacent sides of the frame assembly 300, and 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 completed by the machining center to the first rack 101 and the second rack 1021. A door panel is installed on the opening structure 301 to open or close to block the opening structure 301, which can prevent the loading and unloading device from being exposed to the air when it stops, affecting the service life of the actuating mechanism 200, the first rack 101 and the second rack 1021, etc., so as to protect the actuating mechanism 200, the first rack 101 and the second rack 1021.
[0038] After adopting the above technical solution, the present application sets the opening structure 301 at the product feeding station and the product discharging station of the loading and unloading device, while the open structure 302 is connected to the machining center and will not open outward. That is, there is only one opening structure 301 of the frame assembly 300 of the loading and unloading device that opens outward. This opening structure 301 is mainly used for loading and unloading products, so that the number and size of the openings on the outer shell of the frame assembly 300 can be reduced. It can not only realize loading and receiving materials at the same position, but also enable most of the structure of the product rack 100 to be covered by the outer shell to obtain comprehensive protection. At the same time, the present application plans the layout space of the product feeding station, the product discharging station, the first material rack 101, the second material rack 1021, the actuator 200, and the open structure 302, and the movement routes of the actuator 200 and the material discharging mechanism 104, so as to save the layout space inside the frame assembly 300, ensure the compactness and use safety of the loading and unloading device, and prevent the actuator 200 and the product rack 100 from being exposed outside the frame assembly 300. In this way, whether the loading and unloading device is stopped or working, it can be protected, solving the safety hazards existing when the actuator 200 and the product rack 100 are exposed during work, effectively avoiding the direct contact between the actuator 200 and the product rack 100 and the water vapor in the air, affecting their service life, improving the use safety, and ensuring the overall appearance structure of the loading and unloading device.
[0039] In an optional embodiment, the first material rack 101 includes a first frame body 1011 and a first placement plate 1012. The first placement plate 1012 is spaced along the height direction of the first frame body 1011 to form a plurality of first accommodation channels. The material discharging mechanism 104 is installed in one of the first accommodation channels, so that the telescopic assembly 203 can transfer the products placed in the material discharging mechanism 104 to the second material rack 1021, the machining center, or other first accommodation channels of the first material rack 101, with high utilization rate, simplified product rack 100, and effectively reduced manufacturing and maintenance costs.
[0040] In an optional embodiment, the loading and unloading device further includes a placement fixture 400 for fixing the product. A plurality of first limiting grooves are provided on the first placement plate 1012, and a plurality of limiting posts 4011 are provided on the placement fixture 400. The positions of the limiting posts 4011 correspond to the positions of the first limiting grooves, so that when the placement fixture 400 is placed on the first material rack 101, the position of the placement fixture 400 in the first accommodation channel can be restricted by the cooperation of the limiting posts 4011 and the first limiting grooves.
[0041] In an alternative embodiment, the placement fixture 400 includes a placement base 401 and a clamping base 402 for clamping the product. The size of the clamping base 402 is smaller than that of the placement base 401 and is disposed on the placement base 401. The limit posts 4011 are disposed on the side of the placement base 401 away from the clamping base 402, so that the placement base 401 can accommodate clamping bases 402 of different sizes.
[0042] In an alternative embodiment, the loading and unloading device further includes a scanning mechanism. An electronic tag is provided on the placement fixture 400. During the process of the actuating mechanism 200 transferring the products on the first rack 101 and the second rack 1021 to the machining center, the products pass through the position corresponding to the scanning mechanism, so that the scanning mechanism can scan the electronic tag on the placement fixture 400, and then record and store the information of the products or the parts to be processed into the electronic terminal of the loading and unloading device, so as to manage or process the products or the products to be processed on the entire product rack 100 through the electronic terminal. The structure is simple but practical, and greatly improves the production efficiency and reduces the labor cost.
[0043] In an alternative embodiment, the rotating assembly 201 includes a servo motor, a rotating platform, a servo encoder, and a servo driver. The servo motor is used to drive the rotation of the rotating platform. The servo encoder is used to detect and encode the rotation position of the servo motor and feedback it 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 to transfer each product on the first rack 101 and the second rack 1021 to the machining center, or transfer the products on the machining center to each position of the first rack 101 and the second rack 1021.
[0044] In an alternative 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 disposed 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 ensure the position accuracy when the telescopic assembly 203 moves linearly up and down.
[0045] 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 drivingly connected through a telescopic lead screw assembly 2035. The second telescopic frame 2032 and the third telescopic frame 2033 are drivingly connected through a belt drive assembly 2036. The mechanical claw 2034 is disposed on the third telescopic frame 2033. The first telescopic frame 2031 is drivingly connected to the lifting lead screw assembly to achieve the purpose of hanging and telescoping. At the same time, the multi-layer telescopic structure of the telescopic assembly 203 can be realized through the first telescopic frame 2031, the second telescopic frame 2032, and the third telescopic frame 2033, 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 millimeters.
[0046] In an optional embodiment, first mounting bosses 1031 and second mounting bosses 1032 are provided on both sides of the main frame 103. 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. Among them, the height of the rotating platform is lower than the heights of the first mounting boss 1031 and the second mounting boss 1032, ensuring the position accuracy between the lifting assembly 202 and the first material rack 101 and the second material rack 1021 when controlling the up-and-down linear movement of the telescopic assembly 203.
[0047] In an optional embodiment, the rotary 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 through the turntable drive assembly 1024. The turntable drive assembly 1024 is used to drive the second material rack 1021 to rotate relative to the main frame 103 within a range not greater than 120 degrees, so that the operator 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. Among them, the turntable drive assembly 1024 is disposed between the second material rack 1021 and the main frame 103.
[0048] In an alternative embodiment, the rotating tray mechanism 102 further includes a turntable limit component 1023 and a turntable in-place component 1022. The turntable limit component 1023 is disposed outside the main frame 103, and the turntable in-place component 1022 is disposed inside the main frame 103. The connection line of the turntable limit component 1023 and the turntable in-place component 1022 passes through the rotation center of the second rack 1021. This not only ensures that the rotation range does not exceed the set value, avoids interfering with the structure of the main frame 103, and realizes safe and reliable limited-angle rotation, but also enables the second rack 1021 to be symmetrically stressed, avoiding bearing wear between the second rack 1021, the turntable drive component 1024, and the main frame 103 caused by uneven loading. Among them, the turntable in-place component 1022 includes, but is not limited to, a Hall sensor or a photoelectric pair switch.
[0049] In an alternative embodiment, the second rack 1021 includes a second frame body 10211 and a concave second placement plate 10212. The second placement plate 10212 is spaced along the height direction of the second frame body 10211 to form a plurality of second accommodation channels. Two second product placement areas are formed on each second accommodation channel for placing the placement fixture 400 for fixing the product. Among them, the concave inclination angle of the second placement plate 10212 is 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.
[0050] In an alternative 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 and unloading device, so as to ensure that the actuator 200 can transfer the placement fixture 400 to each second product placement area through precise spatial geometric alignment. Similarly, the first rack 101 also has the same number of first product placement areas as the second product placement area.
[0051] In an alternative embodiment, a plurality of second limit slots are provided on the second product placement area, and the positions of the limit posts 4011 on the placement fixture 400 correspond to the positions of the second limit slots, so that when the placement fixture 400 is placed on the second rack 1021, the position of the placement fixture 400 in the second accommodation channel of the second rack 1021 can be limited through the cooperation of the limit posts 4011 and the second limit slots.
[0052] In an alternative 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 there is a placement fixture 400 and / or the in-place condition of the placement fixture 400 on the second product placement area, so that the actuator 200 can stably transfer the placement fixture 400 on the second product placement area according to the detection of the second product detection component 1025, improving the work efficiency and accuracy. Similarly, the first rack 101 is also provided with a first product detection component 1013 on the first product placement area.
[0053] In an alternative embodiment, the turntable drive component 1024 includes a turntable drive gear and a rotary tray handle. The rotary tray handle is arranged on the second frame body 10211, and the turntable drive gear is arranged between the second frame body 10211 and the main frame 103, realizing the dual-mode operation of the limited-angle rotation of the second rack 1021 and manual intervention. Among them, the rotary tray handle is installed within the center-of-gravity projection plane of the second frame body 10211, and its distance from the rotation axis of the second frame body 10211 is 2 / 3 of the rotation radius of the second frame body 10211 to ensure balanced manual force application. The turntable drive gear can realize the automatic rotation of the second frame body 10211 through a driving method such as a driving motor.
[0054] In an alternative embodiment, the feeding mechanism 104 includes a feeding guide rail component 1042, a tray limit component 1045, and a feeding platform 1041 for placing the placement fixture 400 for fixing the product. The feeding platform 1041 is slidably installed on the product rack 100 of the loading and unloading device through the feeding guide rail component 1042. The tray limit component 1045 is arranged at the bottom of the feeding platform 1041 and is used to cooperate with the feeding guide rail component 1042 to limit the moving position of the feeding platform 1041, ensuring the stability of the product after being placed on the feeding platform 1041 and greatly reducing the operation risk of the loading and unloading device during the transfer of the product. Among them, the feeding platform 1041 is the main bearing component for fixing the placement fixture 400; the feeding guide rail component 1042 is a sliding guiding mechanism, including but not limited to linear guide rails, sliders, or rollers, etc., so as to realize the linear movement of the feeding platform 1041 on the product rack 100; the tray limit component 1045 is mainly a mechanical limit to limit the moving position of the feeding platform 1041.
[0055] In an alternative embodiment, the tray limiting assembly 1045 includes a control rod 10451, a drive plate 10452, and a tray limiter 10453.

The control rod 10451 is movably installed on the material discharging platform 1041 and is in transmission connection with the drive plate 10452. One end of the tray limiter 10453 is slidably connected to the drive groove, and the other end of the tray limiter 10453 is used to cooperate with the material discharging guide rail assembly 1042, so that the control rod 10451 can control the tray limiter 10453 to extend out of or retract into the material discharging platform 1041 through the drive groove, for restricting or releasing the movement position of the material discharging platform 1041. Among them, the inclination angle of the drive groove is in the range of 30 degrees to 45 degrees to ensure the force transmission efficiency and avoid too small an angle resulting in a greater mechanical gain. Similarly, the drive groove can also be provided with balls or bushings to reduce friction.
[0056] In an alternative embodiment, the material discharging platform 1041 includes a tray frame 1041a and a material discharging tray 1041b having a tray groove.
