Description

Technical Field

[0001] The present invention relates to the technical field of manipulator loading and unloading, and in particular to a material manipulator loading and unloading device for producing earphone covers. Background Art

[0002] An earphone cover usually refers to the outer shell of a headset. The sound unit of the headset is placed in the earphone cover. During use, the earphone cover fits the user's ear. The earphone cover can protect the sound unit and isolate the sound generated by the sound unit to transmit the sound to the user's ear. The necessary parts of the earphone cover in the prior art include silicone covers, sponge covers, dust covers, outer shells, hook racks and other parts. Different parts of the earphone cover are separately produced and prepared using different production processes. After the multiple parts that make up the earphone cover are produced separately, the multiple parts are usually transported together on a conveyor belt device to the final assembly production and processing table with the help of a conveyor belt device.

[0003] In order to improve the efficiency of loading and unloading various parts in the prior art, a material manipulator is installed on the assembly production and processing table to grab the parts on the conveyor belt equipment. However, the material manipulator in the prior art can basically only grab one object at a time, and the various parts used to assemble the headphone cover parts are small in size and relatively fragmented. The method of grabbing multiple parts one by one will greatly increase the workload of the material manipulator, and it is also difficult for production personnel to control the timing of placing various parts on the conveyor belt equipment, resulting in errors in the material manipulator's grabbing. Summary of the invention

[0004] The present invention proposes a material manipulator loading and unloading device for earphone cover production, which solves the problem in the prior art that when the material manipulator grabs multiple parts, the workload of a single grab is large, and frequent use of the material manipulator to grab multiple parts is prone to errors.

[0005] The technical solution of the present invention is as follows: A material manipulator loading and unloading device for producing earphone covers comprises a grabbing frame arranged on a material manipulator body, and further comprises:

[0006] A slope-type shoveling frame is fixedly connected in the grabbing frame, and the slope-type shoveling frame has a material receiving slope surface for allowing parts to enter the grabbing frame;

[0007] A parallel support plate is slidably arranged in the grabbing frame, and a plurality of parts are gradually arranged in an orderly manner after contacting the parallel support plate;

[0008] A material shifting plate is rotatably arranged on the grabbing frame, and is used to shift a plurality of parts onto the material receiving slope;

[0009] The bent material transport rods are provided in a plurality and are located in the slope-type shoveling frame. The slope-type shoveling frame is provided with a position moving mechanism for driving the plurality of bent material transport rods to move horizontally and increase the height, so as to transport the parts to the material receiving slope.

[0010] In order to make the bent material transport rod contact with the parts, further, a plurality of slots are provided on the material receiving slope, and the bent material transport rod extends to the upper side of the material receiving slope through the slots.

[0011] In order to enable the parallel support plates to move laterally in the grabbing frame, the parallel support plates are further divided into a transverse area and a longitudinal area, wherein a sliding groove is opened on the longitudinal area, a sliding seat is longitudinally slidably connected in the sliding groove, and a screw transmission structure is arranged on the top of the grabbing frame, and the sliding seat is threadedly connected to the screw transmission structure.

[0012] In order to fix the components, further, a mounting groove is opened on the lateral area, an elastic extrusion plate is arranged on the inner bottom wall of the mounting groove, and a plurality of raised extrusion pieces are fixedly connected to the top of the material receiving slope. After the raised extrusion pieces come into contact with the elastic extrusion plate, the elastic extrusion plate is squeezed to tilt toward the direction of the material removing plate to fix the components.

[0013] In order to rotate the material stripping plate, multiple parts are pushed onto the material receiving slope. Furthermore, a rotating shaft is rotatably connected to the grabbing frame, and the material stripping plate is fixedly connected to the rotating shaft. Multiple tension grooves are opened at the bottom of the material stripping plate, so that multiple arc-shaped material stripping pieces are formed at the bottom of the material stripping plate.

[0014] In order to move the parts onto the material receiving slope, further, a friction pad is provided on the top of the bottom of the bent material transport rod, and the friction pad moves the parts onto the material receiving slope after contacting the parts.

[0015] In order to synchronously drive the movement of multiple bent material transport rods, further, bent slide rails are fixedly connected to the inner walls on both sides of the slope-type shoveling frame, and matching sliding blocks are slidably arranged in the bent slide rails, and a positioning groove is fixedly connected between the two sliding blocks.

[0016] In order to move the bent material transport rod into the corresponding slot, further, the bent material transport rod is slidably arranged in the positioning slot through a sliding member, so that the bent material transport rod moves into the corresponding slot.

[0017] In order to adapt to the height change when the adjustment chute moves, further, a sliding cylinder is horizontally slidably connected to the inner bottom wall of the slope-type shoveling frame, and a mounting plate is longitudinally slidably connected in the sliding cylinder, and the mounting plate is fixedly connected to the bottom of the adjustment chute.

[0018] In order to improve the angle adjustment range of the grabbing frame, further, a connecting shaft seat is fixedly connected to the top of the grabbing frame, and the connecting shaft seat is arranged on the moving end of the material manipulator body.

[0019] The working principle and beneficial effects of the present invention are:

[0020] 1. In the present invention, in order to reduce the workload of the material manipulator body, during the use of the present invention, multiple components that make up the earphone cover can be grabbed and loaded and unloaded simultaneously. By moving the multiple earphone cover components to the material receiving slope and using the material picker plate to push the multiple earphone cover components, the material manipulator body can move the grabbing frame and the internal earphone cover components to complete the loading and unloading operations of the multiple earphone cover components. Since there are large differences in the appearance, material and quality of the earphone cover components, during the use of the present invention, the positions of the multiple bent material transport rods can be adjusted according to the arrangement positions of the multiple earphone cover components during the conveying process. For some earphone cover components that occupy a larger area, more bent material transport rods can be used to perform better material transport operations, thereby improving the convenience of loading and unloading operations of the multiple earphone cover components.

[0021] 2. In the present invention, in order to reduce the difference in conveying speeds among multiple components belonging to the same group of earphone covers during movement, the multiple components are firstly contacted with the lateral areas of the parallel support plates in sequence so that the multiple components are arranged neatly, and then the multiple components are moved to the receiving slope by using a material transfer plate and a plurality of bent material transport rods in coordination.

DETAILED DESCRIPTION

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, this embodiment proposes a material manipulator loading and unloading device for headphone cover production, including a grabbing frame 1, which is arranged on a material manipulator body 2. A connecting shaft seat 3 is fixedly connected to the top of the grabbing frame 1, and the connecting shaft seat 3 is arranged on the moving end of the material manipulator body 2. The material manipulator body 2 is a technical equipment in the prior art for grabbing parts and realizing material loading and unloading operations. It is a prior art equipment well known to those skilled in the art. The material manipulator body 2 adopts a six-axis drive. The grabbing frame 1 in the present invention is installed on the moving end of the material manipulator body 2 through the connecting shaft seat 3. The material manipulator body 2 can drive the grabbing frame 1 to move at multiple angles along the X-axis, Y-axis and Z-axis, and the material manipulator body 2 can also drive the grabbing frame 1 to flip along the top center point of the connecting shaft seat 3 through the connecting shaft seat 3, thereby realizing all-round movement of the grabbing frame 1.

[0033] The sloped shoveling frame 4 is fixedly connected in the grabbing frame 1. The sloped shoveling frame 4 has a receiving slope 5 for allowing the parts to enter the grabbing frame 1. Multiple earphone cover parts are moved to the receiving slope 5 during the movement, and then the grabbing frame 1 is moved to the specified position, and then the earphone cover parts are moved along the receiving slope 5 to be moved out of the grabbing frame 1.

[0034] The parallel support plate 6 is slidably arranged in the grabbing frame 1, and multiple parts are gradually arranged in order after contacting the parallel support plate 6. The parallel support plate 6 is divided into a transverse area 7 and a longitudinal area 8, wherein a sliding groove is opened on the longitudinal area 8, and a sliding seat 9 is longitudinally slidably connected in the sliding groove. Rotating balls are rotatably arranged on both sides of the sliding seat 9, and the rotating balls are slidably arranged in the sliding groove. A screw transmission structure is arranged on the top of the grabbing frame 1, and the sliding seat 9 is threadedly connected to the screw transmission structure. The screw transmission structure includes a transmission screw 10, and the transmission screw 10 is rotatably connected to the grabbing frame 1 through a rotating seat. A first drive motor 1 is arranged on the top of the grabbing frame 1. 1. The output end of the first driving motor 11 is fixedly connected to the transmission screw 10, and the transmission screw 10 is threadedly connected to the sliding seat 9. After a plurality of earphone cap parts are contacted with the transverse area 7 in turn, the plurality of earphone cap parts are neatly arranged on one side of the parallel support plate 6, and then the first driving motor 11 is started to drive the transmission screw 10 to rotate. Through the threaded connection relationship between the transmission screw 10 and the sliding seat 9, the longitudinal area 8 slides through the top of the grabbing frame 1, the transverse area 7 gradually rises along the bottom wall of the receiving slope 5, and the longitudinal area 8 gradually protrudes to the upper side of the top of the grabbing frame 1, reserving space for the earphone cap parts to enter the grabbing frame 1;

[0035] A mounting groove is opened on the transverse area 7, and an elastic extrusion plate 12 is arranged on the inner bottom wall of the mounting groove. A plurality of protruding extrusion pieces 13 are fixedly connected to the top of the material receiving slope 5. After the protruding extrusion piece 13 contacts the elastic extrusion plate 12, the elastic extrusion plate 12 is squeezed and tilted in the direction of the material shifting plate 14 to fix the parts. After the earphone cap parts are moved onto the material receiving slope 5 and the parallel support plate 6 is moved, the protruding extrusion piece 13 contacts the elastic extrusion plate 12, so that the elastic extrusion plate 12 is squeezed and tilted in the direction of the material shifting plate 14, and contacts one side of the earphone cap, and cooperates with the material shifting plate 14 and the bent material transport rod 19 to clamp and fix the earphone cap parts.

[0036] The material-dipping plate 14 is rotatably arranged on the grabbing frame 1. The material-dipping plate 14 is used to divert a plurality of parts onto the material-collecting slope 5. The grabbing frame 1 is rotatably connected with a rotating shaft 15. The material-dipping plate 14 is fixedly connected to the rotating shaft 15. A gear box 16 is arranged on the rotating shaft 15. A second drive motor 17 is arranged on the grabbing frame 1. The output end of the second drive motor 17 is matched with the gear box 16 in transmission. When it is necessary to flip the material-dipping plate 14 along the center point of the rotating shaft 15, the second drive motor 17 is started. Through the transmission match between the gear box 16 and the rotating shaft 15, the rotating shaft 15 is driven to rotate precisely in a small arc, so that the material-dipping plate 14 drives the earphone cap parts to move onto the material-collecting slope 5.

[0037] A plurality of tension grooves are provided at the bottom of the stripper plate 14, so that a plurality of arc-shaped stripper pieces 18 are formed at the bottom of the stripper plate 14. Because there are certain differences in the appearances of the plurality of earphone cap components, in order to ensure sufficient contact between the stripper piece and the plurality of earphone cap components, after the arc-shaped stripper piece 18 contacts the earphone cap components, the earphone cap components with lighter mass can be directly pushed by the arc-shaped stripper piece 18, so that the plurality of arc-shaped stripper pieces 18 gradually contact the plurality of earphone cap components, and when the arc-shaped stripper piece 18 first contacts the earphone cap components with heavier mass, the arc-shaped stripper piece 18 will be deformed to a certain extent, so that after the plurality of arc-shaped stripper pieces 18 contact the plurality of earphone cap components, they drive the plurality of earphone cap components to move together.

[0038] The number of the bent material transport rods 19 is set to be multiple, and they are located in the slope-type shoveling frame 4. The slope-type shoveling frame 4 is provided with a position moving mechanism that drives the multiple bent material transport rods 19 to move horizontally and increase the height, so as to transport the parts to the material receiving slope 5. The material receiving slope 5 is provided with multiple slots 20. The bent material transport rods 19 extend to the upper side of the material receiving slope 5 through the slots 20. A friction pad 21 is provided on the top of the bottom of the bent material transport rod 19. After the friction pad 21 contacts the parts, the parts are moved to the material receiving slope 5. The friction pad 21 provided in the present invention is a checkered friction pad 21, that is, a checkered section is provided on the upper surface of the friction pad 21, and the checkered section can effectively contact with the silicone ring, sponge pad and other parts, and the friction pad 21 is also provided with a hook protrusion 22, which can fully contact the side walls of the shell and the dust cover, thereby improving the full material transportation operation of various earphone cap parts.

[0039] Because the occupied areas of different earphone cap components are not consistent, in order to ensure sufficient contact between multiple bending material transport rods 19 and corresponding earphone cap components, the bending material transport rods 19 can be moved to slots 20 at different positions, so that multiple bending material transport rods 19 can be concentrated to fully move a certain earphone cap component.

[0040] The inner walls on both sides of the slope-type shoveling frame 4 are fixedly connected with bending slide rails 23, and matching sliding blocks 24 are slidably arranged in the bending slide rails 23. A positioning slide groove 25 is fixedly connected between the two sliding blocks 24, so that the multiple bending material transport rods 19 can be adjusted in height during the lateral movement, and then when the earphone cap parts that have been initially moved to the material receiving slope 5 are moved, the positioning slide groove 25 and the bending material transport rod 19 are moved together along the moving path of the sliding block 24 in the bending slide rail 23, so that the bending material transport rod 19 can make the friction pad 21 move out through the slot 20 to contact the earphone cap parts during the lateral movement, and then drive the earphone cap parts to move on the material receiving slope 5 during the subsequent movement of the bending material transport rod 19;

[0041] The bending material transport rod 19 is slidably arranged in the adjustment slide groove 25 through the sliding member 26, so that the bending material transport rod 19 moves into the corresponding slot 20. By adjusting the position of the sliding member 26, the bending material transport rod 19 is moved into the corresponding slot 20, so that the bending material transport rod 19 can be moved out through the corresponding slot 20.

[0042] A sliding insert cylinder 27 is connected to the inner bottom wall of the slope-type shoveling frame 4 for transverse sliding movement, and a mounting plug plate 28 is connected to the sliding insert cylinder 27 for longitudinal sliding movement. The mounting plug plate 28 is fixedly connected to the bottom of the adjustment slide groove 25. A driving electric cylinder 29 is provided on the slope-type shoveling frame 4, and the output end of the driving electric cylinder 29 is fixedly connected to the sliding insert cylinder 27. When it is necessary to move the bending material transport rod 19 along the inner wall of the bending slide rail 23, the driving electric cylinder 29 is started to drive the sliding insert cylinder 27 to move transversely, so that the sliding insert cylinder 27, the mounting plug plate 28, the adjustment slide groove 25 and the bending material transport rod 19 and other components move together. Because the adjustment slide groove 25 will change in height during the movement, the mounting plug plate 28 is moved longitudinally in the sliding insert cylinder 27, and the height change of the adjustment slide groove 25 is adapted to the expansion spacing of the mounting plug plate 28 and the sliding insert cylinder 27.

[0043] Working principle of the material manipulator loading and unloading device for the production of headphone covers:

[0044] When using a conveyor belt device to transport multiple earphone cap parts side by side, first move the material manipulator body 2 to move the grabbing frame 1 into the conveying range of the conveyor belt device, and then make the multiple parts contact with the parallel support plate 6 and gradually arrange them neatly, and then drive the parallel support plate 6 to move horizontally through the screw transmission structure, so that the horizontal area 7 moves on the top of the material receiving slope 5, and then drive the rotating shaft 15 and the material picking plate 14 to rotate together, so that the material picking plate 14 initially moves the multiple earphone cap parts to the material receiving slope 5, and then start the driving electric cylinder 29 to drive the sliding insert 27 to move horizontally , so that the sliding insert 27, the mounting insert plate 28, the adjusting slide groove 25 and the bending material transport rod 19 and other components move together, so that the friction pad 21 on the bending material transport rod 19 contacts with the earphone cap parts, and then drives the earphone cap parts to move to the receiving slope 5, and fixes multiple earphone cap parts through the arc-shaped material shifting piece 18, the friction pad 21 and the elastic extrusion plate 12, and then after moving the grabbing frame 1 to the specified position, the arc-shaped material shifting piece 18, the friction pad 21 and the elastic extrusion plate 12 are reset, and the earphone cap parts are moved out of the grabbing frame 1 to complete the loading and unloading operations of the parts.
