[0031] See also Figures 1 to 5 The utility model provides a loading machine, including a frame 1 and a grabbing mechanism 2 arranged on the frame 1. The frame 1 is also provided with a loading platform 11 and a tray supply platform 12. The grabbing mechanism 2 includes a moving component 21, a material manipulator 22 and a tray manipulator 23. The material manipulator 22 and the tray manipulator 23 are both connected to the moving component 21; the empty tray is grabbed from the tray supply platform 12 by the tray manipulator 23 and placed on the loading platform 11, and the material manipulator 22 grabs the material and places it in the tray on the loading platform 11.

[0032] The utility model greatly simplifies the complexity of operation by arranging the material manipulator 22 and the tray manipulator 23 on the same moving component 21, and uses the moving component 21 to drive the material manipulator 22 to grab the material, and drives the tray manipulator 23 to grab the empty tray, thereby improving work efficiency. Moreover, the material manipulator 22 and the tray manipulator 23 are both driven by the same moving component 21, and the structural design is ingenious and compact, which greatly saves occupied space.

[0033] See also Figure 2 The moving component 21 includes an X-axis linear module 211, and the material manipulator 22 and the tray manipulator 23 are connected to the X-axis linear module 211; the material manipulator 22 and the tray manipulator 23 can move along the X-axis direction under the action of the X-axis linear module 211.

[0034] The X-axis linear module 211 includes a guide rail, a slider, and a drive device (such as a stepper motor or servo motor). The guide rail provides a path for linear motion, along which the slider slides. The drive device connects to the slider to achieve its movement. By connecting the material manipulator 22 and the tray manipulator 23 to the same X-axis linear module 211, the complexity and cost of the equipment are reduced.

[0035] See also Figure 1 The loading table 11 and the tray supply table 12 are arranged side by side along the X-axis direction. This design makes it easier for the material manipulator 22 and the tray manipulator 23 to move along the X-axis direction under the action of the X-axis linear module 211, thereby facilitating the placement of empty trays and the grabbing and placement of materials.

[0036] See also Figure 2 The moving component 21 also includes a Y-axis linear module 212, the Y-axis linear module 212 is connected to the X-axis linear module 211, and the material manipulator 22 and the tray manipulator 23 are connected to the Y-axis linear module 212; the material manipulator 22 and the tray manipulator 23 can move along the Y-axis direction under the action of the Y-axis linear module 212.

[0037] The Y-axis linear module 212 includes a guide rail, a slider, and a drive device (such as a stepper motor or servo motor). The guide rail of the Y-axis linear module 212 is arranged perpendicular to the X-axis linear module 211. The slider moves along the guide rail, and the drive device drives the slider via a motor or other power source. The base of the Y-axis linear module 212 is fixed to the slider of the X-axis linear module 211 by bolts or welding, allowing the Y-axis module to move with the X-axis module.

[0038] The movement of the material manipulator 22 and the tray manipulator 23 in the X and Y axes can be controlled by a pre-installed PLC or other control system, which can precisely control movement according to preset paths and requirements. The material manipulator 22 and the tray manipulator 23 can move materials and trays between the loading platform 11 and the tray supply platform 12 through combined X and Y axis motion.

[0039] In practice, the tray manipulator 23 moves along the X-axis to the tray supply platform 12, adjusting its height and angle through Y-axis motion to precisely grasp the tray. Similarly, the material manipulator 22 moves between the loading platform 11 and the material supply area, achieving efficient material transfer through the combined control of the X and Y axes.

[0040] By jointly moving in the X-axis and Y-axis directions, the material manipulator 22 and the tray manipulator 23 can cover a larger working area, thereby achieving more flexible material handling and operation.

[0041] See also Figure 2 The moving component 21 also includes a first Z-axis linear module 213 and a second Z-axis linear module 214. The first Z-axis linear module 213 and the second Z-axis linear module 214 are both connected to the Y-axis linear module 212. The tray manipulator 23 is connected to the first Z-axis linear module 213, and the material manipulator 22 is connected to the second Z-axis linear module 214. Under the action of the first Z-axis linear module 213, the tray manipulator 23 can move along the Z-axis direction, and under the action of the second Z-axis linear module 214, the material manipulator 22 can move along the Z-axis direction.

[0042] Specifically, the first Z-axis linear module 213 and the second Z-axis linear module 214 each include a guide rail, a slider, and a drive device (e.g., a stepper motor or servo motor). The guide rail is mounted perpendicularly to the slider of the Y-axis module, which moves up and down along the Z-axis. The drive device is connected to a control system to achieve precise vertical positioning.

[0043] The tray manipulator 23 is mounted on the slider of the first Z-axis linear module 213 through a bracket, and the material manipulator 22 is mounted on the slider of the second Z-axis linear module 214 through a bracket. This independent installation method allows each manipulator to move independently in the Z-axis direction without interfering with each other.

[0044] The control system can independently control the two Z-axis modules. The tray robot 23 is between the tray supply table 12 and the loading table 11, and can achieve precise grasping and placement through Z-axis lifting.

[0045] See also Figure 3The tray manipulator 23 includes a central support plate 231 and a plurality of support arms 232 extending outward from the central support plate 231. The outer ends of the plurality of support arms 232 are each provided with a vertical connecting rod 233, and the bottoms of the plurality of vertical connecting rods 233 are provided with a tray suction cup 234.

[0046] Specifically, the central support plate 231 is the core part of the manipulator and can be made of lightweight, high-strength materials, such as aluminum alloy or carbon fiber composite materials, to ensure mechanical strength and reduce weight. A plurality of mounting holes are provided on the support plate to facilitate the installation of the support arm 232, and to allow the position of the support arm 232 to be adjusted according to specific operational requirements. The support arm 232 is a structure extending outward from the central support plate 231, and can usually be designed to be 4 to 6, evenly distributed to ensure balance. The length and angle of the support arm 232 can be adjusted according to the size of the tray, and can usually be fixed by bolts or adjusted by the slide 2211. The vertical connecting rod 233 is vertically connected to the outer end of the support arm 232, and the length can be adjusted to accommodate trays of different heights. The tray suction cup 234 is installed at the bottom of the connecting rod and can be a vacuum suction cup.

[0047] During operation, the tray robot 23 descends through the Z-axis module, the suction cup on the support arm 232 contacts the surface of the tray, the vacuum pump starts adsorption, and then the robot is lifted and moved to the target position for placement.

[0048] See also Figure 4 The material manipulator 22 includes a horizontal support plate 221 arranged along the Y-axis direction, and multiple L-shaped mounting plates 222. The vertical plate parts of the multiple L-shaped mounting plates 222 are connected to the horizontal support plate 221, and the horizontal plate parts of the multiple L-shaped mounting plates 222 are all provided with material suction cups 223.

[0049] Specifically, the horizontal support plate 221 can be made of steel or aluminum alloy to ensure sufficient strength and rigidity. The support plate is arranged along the Y-axis direction and is provided with a plurality of mounting holes for fixing the L-shaped mounting plate 222. Each L-shaped mounting plate 222 is composed of a vertical plate and a horizontal plate. The vertical plate is connected to the horizontal support plate 221 by bolts or welding to ensure stability. The horizontal plate is provided with a plurality of mounting holes for installing the material suction cup 223. The hole position can be adjusted according to the material specifications. The horizontal plate portion of each L-shaped mounting plate 222 is provided with a material suction cup 223. The material suction cup 223 is a vacuum suction cup. The material suction cup 223 is connected to a vacuum pump or an air source, and adsorption and release are achieved through a pipeline system.

[0050] During operation, the material manipulator 22 moves to the material location via the X-axis, Y-axis, and Z-axis linear modules. Once the material suction cup 223 contacts the material surface, the vacuum system activates, generating negative pressure to absorb the material. The material manipulator 22 moves to the target location and releases the material suction cup 223 to complete the material placement.

[0051] In one embodiment, the horizontal support plate 221 is provided with a sliding groove 2211 along the Y-axis direction, and the vertical plate portion of the L-shaped mounting plate 222 is adjustably connected to the sliding groove 2211 .

[0052] Specifically, the vertical plate portion of the L-shaped mounting plate 222 is designed with a slider that engages with the slide slot 2211. The slider is secured to the slide slot 2211 by fasteners (e.g., bolts). The slider can be slid within the slide slot 2211 by loosening the bolts to adjust the position of the L-shaped mounting plate 222. Once adjusted, the bolts are tightened to secure the mounting plate, ensuring that it does not move during operation. This adjustable connection makes position adjustment more convenient and efficient, improving production efficiency.

[0053] Furthermore, the frame 1 is also provided with a first lifting bin 13 and a second lifting bin 14. The first lifting bin 13 is provided with a first lifting linear module 15, and the second lifting bin 14 is provided with a second lifting linear module 16. The loading platform 11 is connected to the first lifting linear module 15, and the tray supply platform 12 is connected to the second lifting linear module 16.

[0054] Specifically, the first lift compartment 13 houses a first linear lift module 15, which includes a guide rail made of high-strength alloy steel and a motorized slider driven by a servo motor for precise vertical movement. The loading platform 11 is secured to the motorized slider via a connector and rises and falls with the slider's movement.

[0055] The second lift compartment 14 houses a second linear lift module 16, similar in structure to the first module. The module's guide rails and sliders work closely together, ensuring stable lifting of the tray feeder 12. The tray feeder 12 is connected to the sliders via self-locking connectors, facilitating adjustment and maintenance.

[0056] During operation, the tray supply platform 12 is controlled by the second linear lift module 16 to descend to the position for removing empty trays. After an empty tray is placed on the tray supply platform 12, it is then controlled by the second linear lift module 16 to ascend to a predetermined position. The tray manipulator 23 grabs the empty tray and places it on the loading platform 11. When the tray placed on the loading platform 11 is full, the loading platform 11 is controlled by the first linear lift module 15 to descend to the position for removing the tray. After the fully filled tray is removed from the loading platform 11, the loading platform 11 is again controlled by the first linear lift module 15 to ascend to the predetermined position.

[0057] See also Figure 5The first lifting bin 13 is also equipped with a first tray rack 17 and a first tray rack linear module 171. The first tray rack linear module 171 is arranged along the Y-axis and is connected to the first tray rack linear module 171. Under the action of the first tray rack linear module 171, the first tray rack 17 can move along the Y-axis. The second lifting bin 14 is also equipped with a second tray rack 18 and a second tray rack linear module 181. The second tray rack linear module 181 is arranged along the Y-axis and is connected to the second tray rack linear module 181. Under the action of the second tray rack linear module 181, the second tray rack 18 can move along the Y-axis. This design allows empty trays to be automatically placed on the tray supply table 12 and fully loaded trays to be removed from the loading table 11, improving intelligence and work efficiency.

[0058] Specifically, the first material tray rack 17 is connected to the frame 1 through the first material tray rack linear module 171. The first material tray rack linear module 171 includes a Y-axis guide rail and an electric slider. The electric slider is driven by a servo motor to ensure smooth and high-precision movement. The first material tray rack 17 is fixed to the slider through a connecting plate so that it can move precisely along the Y-axis.

[0059] The second tray rack 18 has a similar structure to the first tray rack 17. It is connected to the frame 1 via a second tray rack linear module 181. The second tray rack linear module 181 also includes a Y-axis guide rail and an electric slider. The slider is also driven by a servo motor to ensure precise positioning of the tray rack in the Y-axis direction.

[0060] During operation, the first tray rack 17 moves forward and backward along the Y-axis, driven by the first tray rack linear module 171. When the first tray rack 17 moves forward to the predetermined position and the loading platform 11 descends to the predetermined position, the first tray rack 17 and the loading platform 11 overlap with each other. At this time, the trays filled with materials are equivalent to being transferred to the first tray rack 17. The first tray rack 17 moves backward with the trays filled with materials, away from the loading platform 11. Similarly, the second tray rack 18 moves forward and backward along the Y-axis, driven by the second tray rack linear module 181. When the second tray rack 18 moves forward to the predetermined position with the empty trays and the tray supply platform 12 descends to the predetermined position, the second tray rack 18 and the tray supply platform 12 overlap with each other. At this time, the empty trays are equivalent to being transferred to the tray supply platform 12, and the second tray rack 18 moves backward, away from the tray supply platform 12.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
