Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, and in particular to a flipping positioning device and a fully automatic capping machine. Background Technology

[0002] Mobile phone mid-plates are typically manufactured using die casting. However, die-cast mid-plates often have surface defects such as burrs or flash, which need to be removed using a deburring machine or manually. For some fully automatic deburring machines, after deburring the front side of the mid-plate, a robotic arm and suction cups are used to flip it over. However, due to the lack of a suitable positioning device, positional deviations can easily occur after flipping, preventing it from proceeding to the next station for deburring the reverse side. This severely impacts the reliability and efficiency of the fully automatic deburring machine's production.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a flipping positioning device, which effectively solves the technical defects of the existing fully automatic twill machine, which suffers from poor production reliability and low production efficiency due to the lack of a positioning device.

This ensures that after the workpiece is flipped, the specific position of the workpiece can be automatically adjusted so that it can be kept in the preset position, so as to facilitate subsequent transfer to the next work station for operation. This further improves the production reliability and production yield of the fully automatic deburring machine for deburring / de-burring workpieces. Secondly, by setting a first elongated hole in the first positioning block and a second elongated hole in the second positioning block, the positions of the first and second positioning blocks can be adjusted according to the width and length of the workpiece, and the size of the positioning area can be changed to adapt to workpieces of different sizes.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 5 The flipping positioning device 100 provided in the embodiments of this application will now be described. The flipping positioning device 100 includes a flipping mechanism 10 and a positioning fixture 20.

[0026] The flipping mechanism 10 is located on the front side of the positioning fixture 20. The positioning fixture 20 includes a first positioning plate 21, a first positioning block 22 installed on the right side of the upper surface of the first positioning plate 21 and extending back and forth, a second positioning block 23 installed on the front side of the upper surface of the first positioning plate 21 and extending left and right, a first push plate 24 movably installed on the left side of the upper surface of the first positioning plate 21, and a second push plate 25 movably installed on the rear side of the upper surface of the first positioning plate 21. The positioning area 26 is enclosed by the first positioning block 22, the second positioning block 23, the first push plate 24, and the second push plate 25. The first positioning block 22 has a first elongated hole 221 at both the front and rear ends, and the first elongated hole 221 extends left and right. The second positioning block 23 has a second elongated hole 231 at both the left and right ends, and the second elongated hole 231 extends back and forth. The first positioning plate 21 has a first screw hole 211 at the position corresponding to the first elongated hole 221 and a second screw hole 212 at the position corresponding to the second elongated hole 231.

[0027] Understandably, by screwing a screw through the first elongated hole 221 and into the first screw hole 211, the first positioning block 22 can be locked onto the first positioning plate 21. Similarly, by screwing a screw through the second elongated hole 231 and into the second screw hole 212, the second positioning block 23 can be locked onto the first positioning plate 21. Furthermore, by adjusting the positions of the first screw hole 211 and the second screw hole 212 in the first elongated hole 221 and the second screw hole 212 in the second elongated hole 231, the size of the positioning area 26 can be changed to accommodate workpieces of different sizes, thereby improving versatility.

[0028] Specifically, when workpiece positioning is required, the workpiece is loaded into the positioning area 26. The first push plate 24 abuts against the left side of the workpiece and pushes it backward, causing the right side of the workpiece to abut against the first positioning block 22. The second push plate 25 abuts against the rear side of the workpiece and pushes it forward, causing the front side of the workpiece to abut against the second positioning block 23, thus completing the workpiece positioning. Compared with the prior art, firstly, by setting the first positioning block 22, the second positioning block 23, the first push plate 24, and the second push plate 25 on the first positioning plate 21 to enclose the positioning area 26, after the workpiece is loaded into the positioning area, the first positioning block 22, the second positioning block 23, the first push plate 24, and the second push plate 25 can work together to automatically position the workpiece. Positioning ensures that after the workpiece is flipped, its specific position is automatically adjusted to maintain it in a preset position, facilitating subsequent transfer to the next workstation. This further improves the reliability and yield of the fully automatic deburring machine for deburring / de-flaking workpieces. Secondly, by setting a first elongated hole 221 in the first positioning block 22 and a second elongated hole 231 in the second positioning block 23, the positions of the first positioning block 22 and the second positioning block 23 can be adjusted according to the width and length of the workpiece, changing the size of the positioning area 26 to accommodate workpieces of different sizes. Its structure is simple, easy to adjust, and improves the versatility of the positioning fixture 20.

[0029] In some embodiments, the system further includes a first positioning actuator cylinder 241 mounted on the upper surface of the first positioning plate 21. The telescopic rod of the first positioning actuator cylinder 241 extends and retracts laterally toward the positioning area 26. A first base plate 242 is mounted on the telescopic rod of the first positioning actuator cylinder 241, and a first push plate 24 is screwed to the right side of the first base plate 242. The system also includes a second positioning actuator cylinder 251 mounted on the lower surface of the first positioning plate 21. The telescopic rod of the second positioning actuator cylinder 251 extends rearward or retracts forward. A second base plate 252 is mounted on the telescopic rod of the second positioning actuator cylinder 251, and a first clearance notch 213 is provided on the rear surface of the first positioning plate 21. When the telescopic rod of the second positioning actuator cylinder 251 retracts forward, the second base plate 252 can enter the first clearance notch 213. This structure further reduces the size of the space occupied by the second push plate 25 around the positioning fixture 20, thereby facilitating the installation of the flipping positioning device 100 on a fully automatic tasseling machine.

[0030] Specifically, the second push plate 25 includes a first vertical plate 2501, a first horizontal plate 2502 bent forward from the top of the first vertical plate 2501, and a second vertical plate 2503 bent downward from the front end of the first horizontal plate 2502. The first vertical plate 2501 has a third elongated hole 2504 extending through its front and rear surfaces, with the third elongated hole 2504 extending vertically. The second substrate 252 has a third screw hole 2521 corresponding to the third elongated hole 2504. When assembling the second push plate 25, the third elongated hole 2504 is aligned with the third screw hole 2521, and screws are threaded through the third elongated hole 2504 and screwed into the third screw hole 2521 to fix the second push plate 25 to the second substrate 252. At the same time, the different positions of the third screw hole 2521 relative to the third elongated hole 2504 can be adjusted, allowing the second push plate 25 to be adjusted to different heights to accommodate workpieces of different thicknesses for positioning, which further improves its versatility.

[0031] More specifically, by setting the second push plate 25 with a first vertical plate 2501, a first horizontal plate 2502 bent forward from the top of the first vertical plate 2501, and a second vertical plate 2503 bent downward from the front end of the first horizontal plate 2502, the space in the vertical direction of the first positioning plate can be fully utilized, reducing its occupied area in the fully automatic burr machine; at the same time, the folded second push plate 25 can be adapted to different sizes of workpieces, and combined with the structure of the first clearance notch, the second positioning actuator cylinder can complete the movement of the second push plate to adjust the distance in the front and rear directions of the workpiece with minimal extension and retraction stroke.

[0032] In other embodiments, the flipping mechanism 10 includes a gripper assembly, a rotation actuator for driving the gripper assembly to rotate, a horizontal displacement actuator for driving the gripper assembly to move back and forth into or out of the positioning area 26, and a vertical displacement actuator for driving the gripper assembly to move up and down.

[0033] Specifically, the vertical displacement actuator is a first actuator cylinder 11, which is fixedly mounted on the front side of the first positioning plate 21 via a first mounting plate 111 and is spaced apart from the first positioning plate 21. The telescopic rod of the first actuator cylinder 11 can extend vertically upward or retract vertically downward. A first horizontal mounting plate 112 is mounted on the telescopic rod of the first actuator cylinder 11. The horizontal displacement actuator is fixedly mounted on the first horizontal mounting plate 112. The horizontal displacement actuator is a first guide rail slide cylinder 12, which includes a first cylinder body 121 fixedly mounted on the upper surface of the first horizontal mounting plate 112, a first slide 122 that can move horizontally back and forth on the first cylinder body 121, and a first telescopic rod 123 that extends and retracts from the first cylinder body 121 and connects to the first slide 122.

[0034] Furthermore, the rotary actuation assembly includes an L-shaped mounting plate 131 fixedly mounted on the upper surface of the first slide 122 and a rotary actuation cylinder 13 fixedly mounted on the front surface of the L-shaped mounting plate 131. The gripper assembly is fixedly mounted on the output end of the rotary actuation cylinder 13. The gripper assembly is a gripper cylinder 14, and the output end of the gripper cylinder 14 is provided with two gripping claws 141 with an upper and lower spacing. When the gripper cylinder 14 drives the two gripping claws 141 to move closer to each other, it can clamp the workpiece.

[0035] More specifically, the front surface of the first positioning plate 21 is provided with a second clearance notch 214. The front-back direction of the second clearance notch 214 is defined as the first width w1, and the front-back direction of the second positioning block 23 is defined as the second width w2. The first width w1 is greater than the second width w2. The distance by which the two clamping claws 141 move away from their opening is defined as the first height h1. The first height h1 of the opening of the two clamping claws 141 is greater than the thickness of the workpiece. With this structure, the workpiece can be placed flat on the upper surface of the first positioning plate 21 and can be gripped and rotated by the clamping claws 141. Compared with the structure of using a robot arm and a suction cup in the traditional technology, it can simplify the setting of the vacuum suction system and further reduce the energy consumption of the equipment. It can also simplify the overall structure of the flipping positioning device 100, thereby reducing manufacturing costs and improving the convenience of later maintenance.

[0036] It should be noted that there are two second positioning blocks. The two second positioning blocks are located on the front side of the upper surface of the first positioning plate and on both sides of the second clearance notch, and the front surface of the second positioning block is flush with the front surface of the first positioning plate.

[0037] In other embodiments, a fully automatic deburring machine (not shown in the figure) is also included, which is equipped with a flipping and positioning device 100. By setting the flipping and positioning device 100, the position of the workpiece can be automatically adjusted and the flipping operation can be completed, so that it can be kept in a preset position, so as to facilitate subsequent transfer to the next work station for operation, thereby further improving the production reliability and production yield of the fully automatic deburring machine for deburring / de-burring operations on workpieces.

[0038] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
