Description

Technical Field

[0001] This utility model relates to the field of loading and unloading of material trays, and in particular to a material tray lifting module. Background Technology

[0002] In existing material handling processes, traditional material lifting methods often suffer from low efficiency, insufficient stability, and difficulty in adapting to diverse production needs. For example, some older lifting devices have complex structures, high maintenance costs, and are prone to shaking or jamming during lifting, which not only affects production efficiency but may also damage the material tray and the materials on it. Furthermore, with the increasing prevalence of automated production lines, higher demands are placed on the precision, speed, and reliability of material lifting modules, which many existing lifting modules can no longer meet. Therefore, developing a highly efficient, stable, and adaptable material lifting module is particularly important. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a material tray lifting module that automatically realizes the loading and unloading of material trays.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a material tray lifting module, including a full material tray lifting component and an empty material tray lifting component arranged side by side. Both the full material tray lifting component and the empty material tray lifting component include a mounting frame. The mounting frame is provided with a cavity for accommodating a feeding trolley. One end of the cavity is an opening end for the feeding trolley to enter.

[0005] The mounting frame is equipped with a tray lifting mechanism for grabbing a full tray on the feeding trolley or placing an empty tray on the feeding trolley. The top of the full tray lifting assembly and the empty tray lifting assembly are equipped with a tray support translation mechanism for supporting the tray and moving the tray from the full tray lifting assembly to the empty tray lifting assembly.

[0006] Furthermore, the material tray lifting mechanism includes a gripper mounting plate, with gripper assemblies mounted at both ends of the gripper mounting plate, a through hole in the middle of the gripper mounting plate, and a top block at the through hole;

[0007] The mounting bracket is provided with a first servo drive module, which includes a drive block located in a through hole. When the first servo drive module drives the drive block to rise, the drive block abuts against the top block and drives the gripper mounting block to rise.

[0008] Furthermore, the mounting bracket is provided with a first vertical guide rail and a second vertical guide rail in parallel, and the two ends of the gripper mounting plate are slidably connected to the first vertical guide rail and the second vertical guide rail via sliders.

[0009] Furthermore, the gripper assembly includes a gripper arm and a first drive cylinder for driving the gripper arm to move horizontally, and also includes a detection sensor disposed on the gripper mounting plate or the gripper assembly for detecting the presence or absence of the material tray.

[0010] Furthermore, the tray support translation mechanism includes a support plate, on which a positioning pin is provided that mates with a through hole at the bottom of the tray, and also includes a second servo drive module that drives the support plate to move laterally on the support brackets of the full tray lifting assembly and the empty tray lifting assembly.

[0011] Furthermore, the cavity opening end of the mounting frame is provided with a pushing mechanism for the material feeding trolley.

[0012] Furthermore, the pushing mechanism includes a rotating shaft with its two ends rotatably connected to the mounting frame, a push rod fixedly connected to the rotating shaft via a connecting rod, and a second driving cylinder with its tail end rotatably connected to the mounting frame and its driving end rotatably connected to the rotating shaft. When the second driving cylinder drives the rotating shaft to rotate, the push rod moves in an arc around the rotating shaft.

[0013] The beneficial effects of this utility model are as follows: This structure achieves efficient and stable loading and unloading of material trays by setting up parallel full-tray lifting components and empty-tray lifting components. The material tray lifting mechanism can accurately grab full trays from the feeding trolley or place empty trays onto the feeding trolley, greatly improving the accuracy and efficiency of loading and unloading. Simultaneously, the addition of a material tray support translation mechanism enables smooth movement of the material tray between the full-tray lifting components and the empty-tray lifting components, further enhancing the stability and adaptability of the entire module.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, an embodiment of this application discloses a material tray lifting module, including a full material tray lifting component 1 and an empty material tray lifting component 2 arranged side by side. Both the full material tray lifting component 1 and the empty material tray lifting component 2 include a mounting frame. The mounting frame is provided with a cavity for accommodating a feeding trolley. One end of the cavity is an opening for the feeding trolley to enter.

[0021] The mounting frame is equipped with a tray lifting mechanism 3 for grabbing a full tray on the feeding trolley or placing an empty tray on the feeding trolley. The top of the full tray lifting assembly 1 and the empty tray lifting assembly 2 is equipped with a tray support translation mechanism 4 for supporting the tray and moving the tray from the full tray lifting assembly 1 to the empty tray lifting assembly 2.

[0022] In actual operation, when the feeding trolley carrying a full tray enters the cavity of the mounting frame from the open end, the tray lifting mechanism 3 starts to operate. First, the tray lifting mechanism 3 at the full tray lifting component 1 grabs the top full tray and moves it upward. When the full tray moves to a certain height, the tray support translation mechanism 4 moves to below the full tray. The tray lifting mechanism 3 at the full tray lifting component 1 places the full tray on the tray support translation mechanism 4 and lowers it to prepare to take the next full tray. The external material handling robot performs material handling operations inside the full tray. When the products on the full tray are all taken, the tray support translation mechanism 4 drives the tray to move to the empty tray lifting component 2. The tray lifting mechanism 3 at the empty tray lifting component 2 grabs the empty tray. Then, the tray support translation mechanism 4 moves to the full tray lifting component 1 to receive the next full tray. The tray lifting mechanism 3 at the empty tray lifting component 2 stacks the grabbed empty trays downward onto the feeding trolley.

[0023] The above-described structure makes the entire material tray lifting process more automated and intelligent. The side-by-side arrangement of the full material tray lifting component 1 and the empty material tray lifting component 2 not only optimizes space utilization but also makes the transition between full and empty material trays faster and smoother.

[0024] In this embodiment, the material tray lifting mechanism 3 includes a gripper mounting plate 301. Gripper assemblies are respectively mounted on both ends of the gripper mounting plate 301. A through hole 302 is provided in the middle of the gripper mounting plate 301, and a top block 303 is provided at the through hole 302. A first servo drive module 304 is provided on the mounting frame. The first servo drive module 304 includes a drive block 305. The drive block 305 is located in the through hole 302. When the first servo drive module 304 drives the drive block 305 to rise, the drive block 305 abuts against the top block 303 and drives the gripper mounting block to rise.

[0025] Specifically, during the driving process, the first servo drive module 304 is activated, and its internal drive block 305 begins to rise under the precise control of the servo motor. The drive block 305 abuts against the top block 303 in the middle of the gripper mounting plate 301. Since the top block 303 is fixedly connected to the gripper mounting plate 301, when the drive block 305 applies an upward thrust to the top block 303, the entire gripper mounting plate 301 is also driven upward. When the drive block 305 moves downward, the gripper mounting plate 301 moves downward synchronously under the action of gravity.

[0026] In the above structure, the drive block 305 and the gripper mounting plate 301 are designed to float. If the stacked trays are tilted, when the gripper assembly moves downward to grab the tray, even if one of the gripper assemblies hits the tray, it can float up and down. The trays or gripper assemblies will not be damaged due to excessive downward driving force of the drive block 305, thus effectively protecting the safety of the trays and equipment.

[0027] In this embodiment, a first vertical guide rail 306 and a second vertical guide rail 307 are arranged in parallel on the mounting bracket, and the two ends of the gripper mounting plate 301 are slidably connected to the first vertical guide rail 306 and the second vertical guide rail 307 through sliders.

[0028] Specifically, when the first servo drive module 304 drives the gripper mounting plate 301 to rise or fall, the configuration of the first vertical guide rail 306 and the second vertical guide rail 307 provides precise guidance for the movement of the gripper mounting plate 301. This design not only reduces friction and wear during movement but also improves the operating efficiency and lifespan of the entire tray lifting module.

[0029] In this embodiment, the gripper assembly includes a gripper arm 308 and a first drive cylinder 309 for driving the gripper arm 308 to move horizontally, and also includes a detection sensor 310 disposed on the gripper mounting plate 301 or the gripper assembly for detecting the presence or absence of a material tray.

[0030] Specifically, when a material tray needs to be grasped, the detection sensor 310 monitors in real time whether a material tray is present at the gripper assembly. If a material tray is present, the first drive cylinder 309 is activated, driving the gripper arm 308 to move horizontally, thereby clamping the material tray. In addition, the detection sensor 310 can prevent the gripper assembly from grasping without a material tray, thus effectively protecting the safety of the gripper assembly and the equipment.

[0031] In this embodiment, the tray support translation mechanism 4 includes a support plate 401, on which a positioning pin 402 is provided that cooperates with the bottom through hole 302 of the tray, and also includes a second servo drive module 403 that drives the support plate 401 to move laterally on the brackets of the full tray lifting assembly 1 and the empty tray lifting assembly 2.

[0032] Specifically, when the support plate 401 moves to the bottom of the full material tray, the gripper assembly releases, allowing the full material tray to fall onto the support plate 401. The positioning pin 402 and the through hole 302 at the bottom of the tray are used to achieve precise positioning of the full material tray on the support plate 401, thereby ensuring the accuracy of the position of the full material tray when picking up materials. After the materials on the full material tray are picked up, the second servo drive module 403 drives the support plate 401 to move, moving the support plate 401 together with the empty material tray on it from the area of ​​the full material tray lifting assembly 1 to the area of ​​the empty material tray lifting assembly 2.

[0033] In this embodiment, a pushing mechanism 5 for feeding a material onto a trolley is provided at the cavity opening end of the mounting frame. The pushing mechanism 5 includes a rotating shaft 501, with both ends of the rotating shaft 501 rotatably connected to the mounting frame. It also includes a push rod 502, which is fixedly connected to the rotating shaft 501 via a connecting rod 503. Furthermore, it includes a second driving cylinder 504, the tail end of which is rotatably connected to the mounting frame. The driving end of the second driving cylinder 504 is rotatably connected to the rotating shaft 501. When the second driving cylinder 504 drives the rotating shaft 501 to rotate, the push rod 502 moves in an arc around the rotating shaft 501.

[0034] Specifically, once the feeding trolley is full of material trays, it is pushed into the cavity. Then, the second drive cylinder 504 is activated, its drive end pushing the rotating shaft 501 to rotate. Since the push rod 502 is fixedly connected to the rotating shaft 501 via the connecting rod 503, when the rotating shaft 501 rotates, the push rod 502 will move in an arc around the rotating shaft 501. This arc motion allows the push rod 502 to push the full material trays on the feeding trolley inwards, ensuring that the full material trays are neatly and stably positioned on the feeding trolley, facilitating the subsequent gripping operation of the material tray lifting mechanism 3.

[0035] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
