[0003] Nowadays, in the COB board processing process, COB materials are generally automatically loaded and unloaded using material handling devices to save labor costs. However, during the unloading process, the existing material handling devices need to first use a suction mechanism to adsorb the materials placed in the working area, and then place them in the transfer area. Then, the materials in the transfer area are pushed into the material box by a pushing mechanism to complete the stacking and packaging. The material handling device including the suction mechanism and the pushing mechanism is relatively complex, and has a high failure rate and cost. Utility Model Content

[0018] In some embodiments of the present invention, the suction assembly further includes a negative pressure machine and a diverter, the negative pressure machine is connected to the diverter, the diverter is installed on the top surface of the mounting plate and is connected to the plurality of suction heads.

[0019] In some embodiments of the present invention, the rack includes a transfer table and a workbench arranged in layers, the transfer table surface is provided with the transfer area, the workbench surface is provided with the work area, and the transfer table surface is arranged higher than the workbench surface.

[0020] In some embodiments of the utility model, the top of the transfer table is recessed with a placement groove, the bottom wall of the placement groove is recessed to form an avoidance groove, the placement groove and the avoidance groove are both arranged through the opposite sides of the horizontal moving direction of the suction component, the placement groove is used to place COB materials, and the avoidance groove is used to avoid the pushing piece.

[0021] In the technical solution of the utility model, the material handling device can realize loading and unloading by driving the suction component through the driving mechanism, and can also drive the pusher to move through the driving mechanism, so that the pusher pushes against the material to realize the pushing and loading.

After the suction head completes the adsorption, the driving mechanism drives the suction assembly to rise to a high position. At this time, the bottom end of the push rod is flush with the COB material on the transfer area. When the suction assembly moves above the transfer area, the pusher pushes against the material on the transfer area. After the suction assembly is aligned with the transfer area, the pusher is misaligned with the transfer area. After the suction assembly moves down until the material is placed in the transfer area, the suction head is separated from the COB material, and the suction assembly is reset or cyclically transports the next COB material. In this way, the unloading and pushing actions can be completed at the same time, which is more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] See also Figure 1 and Figure 2 The utility model proposes a material handling device 100, including a frame 10, a driving mechanism 20, a suction assembly 30 and a pushing piece 40, wherein the frame 10 has a working area 11 and a transfer area 12 for placing materials, and the working area 11 and the transfer area 12 are arranged at intervals in the horizontal direction; the driving mechanism 20 is installed on the frame 10; a suction head 34 is arranged on the bottom surface of the suction assembly 30, and the suction head 34 is used to absorb COB materials 200, the suction assembly 30 is connected to the driving mechanism 20, and moves above the working area 11 and the transfer area 12 under the drive of the driving mechanism 20 to transport the COB materials 200; the pushing piece 40 is connected to the side of the suction assembly 30 close to the transfer area 12, and the bottom end of the pushing piece 40 protrudes from the bottom surface of the suction assembly 30, and the pushing piece 40 is used to move under the drive of the driving mechanism 20 to push away the COB material 200 located in the transfer area 12.

[0034] The above-mentioned working area 11 and transfer area 12 can be set on the horizontal surface of the same height, and can also be set on the horizontal surfaces of different heights. The power source of the driving mechanism 20 can be a servo motor, a stepper motor, a cylinder, etc. There are many ways for the driving mechanism 20 to drive the suction component 30 to move. The two can be connected by a screw rod 24 and can also be connected by a gear rack transmission. Again, no specific limitation is made.

[0035] In the above-mentioned suction component 30, the suction head 34 generally absorbs the COB material 200 by gas adsorption. The COB material 200 can be separated from the suction head 34 by pressurizing the suction head 34 through the suction head 34 component itself, so that the pressure difference between the COB material 200 and the suction head 34 is balanced, and the COB material 200 falls off naturally. The COB material 200 can also be removed from the suction head 34 by other mechanisms. For example, in some embodiments of the present utility model, the material handling device 100 also includes two clamping claw mechanisms, and the two clamping claw mechanisms are arranged on opposite sides of the working area 11. When the driving mechanism 20 drives the suction component 30 to transport the COB material 200 to the top of the working area 11, the two clamping claw mechanisms clamp the COB material 200. The driving mechanism 20 drives the suction component 30 to reset, so that the COB material 200 is separated from the suction head 34, and finally the clamping claws are opened to facilitate subsequent material pushing. There are many specific implementation methods of the suction component 30, which are not listed here one by one.

[0036] The pusher 40 is generally configured as a rod, and the pusher 40 can be connected to the suction assembly 30 by welding, screw fixing, or threaded connection, etc., which is not specifically limited here.

[0037] In the technical solution of the utility model, the material handling device 100 can realize loading and unloading by driving the suction assembly 30 through the driving mechanism 20, and can also drive the pusher 40 to move through the driving mechanism 20, so that the pusher 40 pushes against the material to realize the pushing and loading. Specifically, during the loading process, the COB material 200 is initially in the transfer area 12, and the driving mechanism 20 drives the suction assembly 30 to move from a high position to above the transfer area 12, and then drives it down to the suction head 34 to contact the COB material 200. After the suction head 34 completes the adsorption, the driving mechanism 20 drives the suction assembly 30 to rise to a high position, and then moves to above the working area 11, and finally descends to place the COB material 200 in the working area 11, and the suction head 34 is separated from the COB material 200, and the suction assembly 30 is reset or circulated to transport the next COB material 200.

[0038] During the material unloading process, the driving mechanism 20 drives the suction component 30 to move above the working area 11, and then descends until the suction head 34 contacts the COB material 200. After the suction head 34 completes the adsorption, the driving mechanism 20 drives the suction component 30 to rise to a high position, and then moves to above the transfer area 12, and finally descends to place the COB material 200 in the transfer area 12. The suction head 34 is separated from the COB material 200, and the suction component 30 is raised to a high position. After completing the material unloading action, the material is pushed. The driving mechanism 20 drives the suction component 30 to move to the right side of the transfer area 12, and makes the bottom end of the pusher flush with the COB material 200 located on the transfer area 12. The pusher moves and pushes the COB material 200 to leave the transfer area 12, completing the pushing action. Finally, the suction component 30 is reset or circulated to transport the next COB material 200.

[0039] Alternatively, during the unloading process, the driving mechanism 20 drives the driving mechanism 20 to drive the suction component 30 to move above the working area 11, and then descends until the suction head 34 contacts the COB material 200. After the suction head 34 completes the adsorption, the driving mechanism 20 drives the suction component 30 to rise to a high position. At this time, the bottom end of the push rod is flush with the COB material 200 located on the transfer area 12. When the suction component 30 moves to above the transfer area 12, the pusher pushes against the material on the transfer area 12. After the suction component 30 is aligned with the transfer area 12, the push rod is misaligned with the transfer area 12. After the suction component 30 moves down until the material is placed in the transfer area 12, the suction head 34 is separated from the COB material 200, and the suction component 30 is reset or circulated to transport the next COB material 200. In this way, the unloading and pushing actions can be completed at the same time, which is more efficient.

[0040] In some embodiments of the present invention, the suction assembly 30 includes a connecting member 31 and a mounting plate 32, the connecting member 31 is connected to the driving mechanism 20, the mounting plate 32 is fixed to the connecting member 31, the mounting plate 32 is arranged horizontally, one end of the pushing member 40 is fixed to the top surface of the mounting plate 32, and the other end of the pushing member 40 is bent and extended to the bottom of the mounting plate 32. With such an arrangement, it is more convenient to install the pushing member 40 from the top to the top surface of the mounting plate 32. The above-mentioned connecting member 31 has various structures, which can be a drag plate, a bracket, etc., and is arranged according to specific circumstances.

[0041] In some embodiments of the utility model, the driving mechanism 20 includes a driving motor 22, a sliding seat 23 and a vertical driving member 25. The frame 10 is provided with a horizontal guide rail 13. The driving motor 22 and the sliding seat 23 are connected to each other through a screw rod 24 to drive the sliding seat 23 to move horizontally. The sliding seat 23 cooperates with the horizontal guide rail 13; the vertical driving member 25 is installed on the sliding seat 23 and drives the connecting member 31.

[0042] Through the above scheme, the driving mechanism 20 can drive the screw 24 to rotate through the driving motor 22, so that the sliding seat 23 and the vertical driving member 25 installed on the sliding seat 23 slide in the horizontal direction, and the vertical driving member 25 is used to realize the vertical movement of the connecting member 31, so that the connecting member 31 can drive the mounting plate 32 to move in both vertical and horizontal directions to realize lifting and translation.

[0043] The vertical drive member 25 can be a linear motor. In some embodiments of the present invention, the vertical drive member 25 is a cylinder, and the output end of the cylinder is fixed to the connecting member 31. In this embodiment, the vertical drive member 25 is set as a cylinder, which has high reliability and efficiency, has light and flexible motion control, and has strong controllability, and can achieve precise position control and force control.

[0044] In order to improve the movement stability of the sliding seat 23, in some embodiments of the present invention, a vertical guide rail 14 is provided on the side of the sliding seat 23, and one side of the connecting member 31 is slidably connected to the vertical guide rail 14. In this way, the sliding seat 23 slides more steadily and smoothly.

[0045] The pusher 40 can be connected to the top surface of the mounting plate 32 by welding. In other embodiments of the present invention, a through hole 41 is provided in the portion of the pusher 40 located directly above the mounting plate 32, and an assembly hole is correspondingly provided on the top surface of the mounting plate 32. The screw connection member passes through the through hole 41 and is assembled in the assembly hole. This arrangement is convenient for assembly, and when the pusher 40 is broken, it is convenient to disassemble and replace it.

[0046] The bottom end of the push rod is protruding from the bottom surface of the suction assembly 30 to avoid the suction assembly 30 from abutting against the surface of the working area 11. As for the height of the bottom end of the push rod relative to the suction head 34, it is set according to the specific situation. In some embodiments of the utility model, the transfer area 12 is provided with an avoidance groove 152, and the avoidance groove 152 can allow the pusher 40 and the suction head 34 to pass through. In this embodiment, the bottom end of the pusher 40 can be set higher than the bottom end of the suction head 34.

[0047] In other embodiments of the present invention, the bottom end of the pusher 40 is lower than the suction head 34. In this way, regardless of whether the transfer area 12 is provided with the avoidance groove 152, the material handling device 100 can realize the handling by simultaneously performing the material feeding and pushing, or by performing the material feeding and pushing sequentially.

[0048] In other embodiments of the present invention, the bottom end of the material pushing member 40 is flush with the suction head 34. The material handling device 100 can realize material handling by first unloading the material and then pushing the material.

[0049] In other embodiments of the present invention, the suction assembly 30 further includes a negative pressure machine and a diverter 33, the negative pressure machine is connected to the diverter 33, the diverter 33 is installed on the top surface of the mounting plate 32, and is connected to the plurality of suction heads 34.

[0050] The negative pressure machine can be a vacuum pump or a vacuum generator, etc. The negative pressure machine is generally installed on the frame 10, and can also be installed on the base plate 321. It is set according to specific circumstances and is not limited here.

In this way, the bottom plate 322 with different numbers and arrangements of suction heads 34 can be replaced according to different models of COB materials 200, which has higher applicability.

[0052] The base plate 321 and the bottom plate 322 can be detachably connected by screws or fixed by snap-fits. In some embodiments of the present invention, the base plate 321 and the bottom plate 322 are fixed by magnetic attraction, and the disassembly and assembly are relatively convenient. The above-mentioned diverter 33 is generally provided with a large-caliber air inlet connected to the negative pressure machine, and a plurality of smaller-caliber diverter pipe openings are connected to a plurality of suction heads 34 in a one-to-one correspondence.

[0054] Please continue reading Figure 1 During the unloading process of the material handling device 100 , the pusher 40 is misaligned with the transfer table 15 , so that the COB material 200 adsorbed by the suction head 34 can be placed on the transfer table 15 , and the pusher 40 will not hit the transfer table 15 .
