Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a material tray collecting and lifting mechanism. Background Art

[0002] In automated production processes, workpieces are typically stored on trays for batch storage and transport. The trays are then stacked on top of each other for storage. During operation, a robot frequently performs transfer operations between the storage area and the workstation. Specifically, the robot grabs the tray and then transports the workpiece to the corresponding workstation.

[0003] It can be seen that when the tray is loaded into the storage area, the robot needs to be moved away from the storage area. Since the loading operation is usually manual, the robot is adjacent to the storage area during the manual operation. This has two disadvantages:

[0004] First, when the operator touches the robot, it will not only cause safety hazards to the operator, but also affect the operating accuracy of the robot;

[0005] Second, when the equipment is turned on by mistake, the robot arm will touch the operator, posing a serious safety hazard.

[0006] It can be seen that the existing material tray storage mechanism has the problem of poor stability. Summary of the Invention

[0007] The purpose of the utility model is to provide a material tray collecting and lifting mechanism with high stability and compact structure in order to solve the above problems existing in the prior art.

[0008] The objectives of this utility model can be achieved through the following technical solutions:

[0009] A material tray collection and lifting mechanism includes a frame, and is characterized in that it also includes a material tray rack, a grabbing assembly, a driving assembly 1 and a driving assembly 2. A guide assembly is provided between the lower end of the material tray rack and the frame. The driving assembly 1 is arranged between the frame and the lower end of the material tray rack. Under the action of the driving assembly 1, the material tray rack can translate left and right relative to the frame. The driving assembly 2 is arranged between the frame and the grabbing assembly. The driving assembly 2 can drive the grabbing assembly to move up and down relative to the frame. In the initial state, the grabbing assembly is located directly above the material tray rack. When the driving assembly 1 drives the material tray rack to move, the material tray rack can be moved out from directly below the grabbing assembly.

[0010] In the above-mentioned tray collecting and lifting mechanism, the tray rack includes a bottom plate and a bracket fixedly connected to the upper part of the bottom plate, the bracket is used to store stacked trays, and the guide assembly is located between the bottom plate and the rack.

[0011] In the above-mentioned material tray collection and lifting mechanism, the guide assembly includes an upper guide plate and a lower guide plate. The upper guide plate is fixedly connected to the frame, and the inner edge of the lower part of the upper guide plate has a recessed guide groove. The outer edge of the bottom plate is embedded in the guide groove. The lower guide plate is fixedly connected to the frame and the lower guide plate rests on the bottom plate.

[0012] In the above-mentioned tray collecting and lifting mechanism, the lower part of the bottom plate has a downwardly protruding connecting plate, the above-mentioned lower guide plate abuts against the inner side of the connecting plate, and the above-mentioned upper guide plate is located at one end of the outer side of the connecting plate.

[0013] In the above-mentioned tray collecting and lifting mechanism, there are two connecting plates, which are symmetrically arranged on both sides of the bottom plate, and the above-mentioned frame has lower guide plates corresponding to the connecting plates one by one.

[0014] In the above-mentioned tray collecting and lifting mechanism, the driving component 1 is a horizontally arranged cylinder, the cylinder body of the cylinder is fixedly connected to the frame, and the piston rod of the cylinder is fixedly connected to the bottom plate.

[0015] In the above-mentioned tray collection and lifting mechanism, the driving assembly includes a motor, a screw rod and a base plate. The screw rod is vertically arranged and axially fixed on the frame. The rotating shaft of the above-mentioned motor is fixedly connected to the screw rod. The above-mentioned base plate is connected to the screw rod and the base plate is located on the upper part of the bracket. The above-mentioned grabbing assembly is connected to the base plate.

[0016] In the above-mentioned tray collecting and lifting mechanism, a cylindrical connecting tube is fixedly connected to the end of the base plate, and the connecting tube is sleeved on the screw rod and the two are threadedly connected.

[0017] In the above-mentioned tray collecting and lifting mechanism, the above-mentioned screw rod and connecting cylinder form a lifting assembly, the number of the lifting assemblies is several, and the motor is connected to the screw rod in one of the lifting assemblies.

[0018] In the above-mentioned tray collection and lifting mechanism, there are several tray racks, each tray rack has a one-to-one corresponding drive component one, the drive component two and the grabbing component are one, a fixed plate is fixedly connected to the edge of the base plate, and several connecting tubes are evenly distributed along the length direction of the fixed plate and the connecting tubes are fixedly connected to the fixed plate.

[0019] Compared with the existing technology, in the material tray collection and lifting mechanism, since the material tray can independently move left and right relative to the frame, after the material tray is moved out by the grabbing assembly, the operator's operation of loading the material tray into the material tray is relatively safe because it is far away from the robot arm. Of course, the corresponding protection effect is also achieved for the robot arm.

[0020] At the same time, the grabbing component can be raised and lowered according to actual conditions, so it can effectively adapt to the material tray of corresponding storage height, and its applicability is relatively high.

[0021] In addition, since the driving component 1 and the driving component 2 are centrally arranged, the entire mechanism occupies relatively less space, the overall structure is relatively high, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains.

[0029] like Figure 1 and Figure 2 and Figure 3As shown, the material tray collection and lifting mechanism includes a frame 1, and also includes a material tray rack 2, a grabbing assembly 3, a driving assembly 1 and a driving assembly 2. A guide assembly is provided between the lower end of the material tray rack 2 and the frame 1. The above-mentioned driving assembly 1 is arranged between the frame 1 and the lower end of the material tray rack 2. Under the action of the driving assembly 1, the material tray rack 2 can translate left and right relative to the frame 1. The above-mentioned driving assembly 2 is arranged between the frame 1 and the grabbing assembly 3. The driving assembly 2 can drive the grabbing assembly 3 to move up and down relative to the frame 1. In the initial state, the grabbing assembly 3 is located directly above the material tray rack 2. When the driving assembly 1 drives the material tray rack 2 to move, the material tray rack 2 can be moved out from directly below the grabbing assembly 3.

[0030] Driving component 1 and driving component 2 are two independent components, that is, the tray rack 2 can independently move left and right relative to the frame 1, and the grabbing component 3 can independently move up and down relative to the frame 1.

[0031] After the tray rack 2 moves, it can be moved out of the frame 1 and away from the grab assembly 3. Once the tray rack 2 is moved out, the operator can load the tray into the tray rack 2 conveniently and in a safe working environment.

[0032] After the trays are stacked on tray rack 2, drive assembly 1 moves tray rack 2 back to directly below gripper assembly 3. After a period of operation, the highest point of the stacked trays will gradually drop lower. At this point, drive assembly 2 drives gripper assembly 3 to perform a corresponding action, allowing gripper assembly 3 to continue to stably grasp the trays.

[0033] The tray rack 2 includes a bottom plate 2a and a bracket 2b fixedly connected to the upper part of the bottom plate 2a. The bracket 2b is used to store stacked trays. The guide assembly is located between the bottom plate 2a and the frame 1.

[0034] The bottom plate 2a plays the role of connecting guides, and the bracket 2b plays the role of loading the tray. It can be seen that the bottom plate 2a and the bracket 2b play the role of each being independent, which effectively improves the stability of the entire tray rack 2.

[0035] The guide assembly includes an upper guide plate 4 and a lower guide plate 5. The upper guide plate 4 is fixedly connected to the frame 1. The inner edge of the lower part of the upper guide plate 4 has a concave guide groove 4a. The outer edge of the base plate 2 is embedded in the guide groove 4a. The lower guide plate 5 is fixedly connected to the frame 1 and the lower guide plate 5 rests on the base plate 2a.

[0036] Under the action of the upper guide plate 4 and the lower guide plate 5, the material tray rack 2 can eventually move smoothly left and right.

[0037] The bottom of the bottom plate 2 a has a downwardly protruding connecting plate 6 , the lower guide plate 5 abuts against the inner side of the connecting plate 6 , and the upper guide plate 4 is located at one end of the outer side of the connecting plate 6 .

[0038] The connecting plate 6 contacts the lower guide plate 5 with a relatively large contact area, thereby improving the guiding stability.

[0039] At the same time, the upper guide plate 4 and the lower guide plate 5 are respectively located on both sides of the connecting plate 6, which further improves the guiding stability and ensures that the material tray frame 2 can move smoothly left and right.

[0040] There are two connecting plates 6 , which are symmetrically arranged on both sides of the bottom plate 2 a . The frame 1 has lower guide plates 5 corresponding to the connecting plates 6 .

[0041] Such a structure further increases the contact area, and ultimately ensures that the material tray rack 2 can translate left and right more stably.

[0042] The first driving component is a horizontally arranged cylinder 7, the cylinder body of the cylinder 7 is fixedly connected to the frame 1, and the piston rod of the cylinder 7 is fixedly connected to the bottom plate 2a.

[0043] The cylinder 7 can stably drive the bottom plate 2a to move horizontally.

[0044] The driving assembly includes a motor 8, a screw rod 9, and a base plate 10. The screw rod 9 is vertically arranged and axially fixed to the frame 1. The rotating shaft of the motor 8 is fixedly connected to the screw rod 9. The base plate 10 is connected to the screw rod 9 and is located on the upper part of the bracket 2b. The gripping assembly 3 is connected to the base plate 10. In this embodiment, the gripping assembly 3 is a robot.

[0045] When the motor 8 drives the screw rod 9 to rotate continuously, the base plate 10 can move up and down smoothly because the base plate 10 is threadedly connected to the screw rod 9.

[0046] A cylindrical connecting tube 11 is fixedly connected to the end of the base plate 10 . The connecting tube 11 is sleeved on the screw rod 9 and the two are threadedly connected.

[0047] The connecting tube 11 can effectively improve the connection stability between the connecting tube 11 and the screw rod 9.

[0048] The screw rod 9 and the connecting tube 11 form a lifting assembly. There are several lifting assemblies, and the motor 8 is connected to the screw rod 9 in one of the lifting assemblies.

[0049] Multiple lifting components share one motor, and this structure can ensure that the substrate 10 moves up and down more smoothly.

[0050] There are several material tray racks, and each material tray rack 2 has a one-to-one corresponding drive component 1. The number of drive component 2 and grabbing component 3 is one. A fixed plate 12 is fixedly connected to the edge of the base plate 10, and several connecting tubes 11 are evenly distributed along the length direction of the fixed plate 12 and the connecting tubes 11 are fixedly connected to the fixed plate 12.

[0051] Such a structure not only improves the compactness of the structure, but also simplifies the structure of the entire mechanism, ensuring that the cost is moderate and the structure is compact, while the stability of the entire mechanism is relatively high.

[0052] In this tray collection and lifting mechanism, since the tray can independently move left and right relative to the frame, after the tray is moved out by the grabbing assembly, the operator's operation of loading the tray into the tray is relatively safe because the operator is far away from the robot arm. Of course, the robot arm is also protected accordingly.

[0053] At the same time, the grabbing component can be raised and lowered according to actual conditions, so it can effectively adapt to the material tray of corresponding storage height, and its applicability is relatively high.

[0054] In addition, since the driving component 1 and the driving component 2 are centrally arranged, the entire mechanism occupies relatively less space, the overall structure is relatively high, and has high practical value.

[0055] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
