Description

Technical Field

[0001] This utility model belongs to the field of thin workpiece flipping technology, and relates to a flipping mechanism, particularly a flipping mechanism suitable for flipping thin workpieces. Background Technology

[0002] With the development of technology, the quality requirements for thin-film components used in 3C products, such as glass, ceramic sheets, microcrystalline glass sheets, and sapphire, are becoming increasingly stringent. However, the thin and fragile structure of 3C sheets cannot withstand too much force, so it is important to avoid deformation or damage to thin workpieces during processing or testing.

[0003] In the prior art, the flipping of workpieces is generally achieved by using a motor-driven gripper to pick up the workpiece and flip it, or by using a motor-driven carrier plate to flip the workpiece on the carrier plate, such as the flipping device in a product testing equipment disclosed in patent application CN202210541284.X.

[0004] However, using grippers to flip workpieces is generally suitable for workpieces with hard surface materials. For thin workpieces, using grippers to flip them will cause deformation of the gripped part of the thin workpiece, affecting the quality of the thin workpiece. If a support plate is used to support the workpiece for flipping, the thin workpiece is light and is prone to falling, causing damage to the thin workpiece. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a flipping mechanism that can adapt to the flipping of thin workpieces without causing deformation or damage to them.

[0006] The objective of this utility model can be achieved through the following technical solution: a flipping mechanism suitable for flipping thin workpieces, comprising:

[0007] The base serves as the supporting structure for the flipping mechanism;

[0008] The flip assembly is mounted on the base and includes a rotating shaft. Two suction cup units are arranged side by side along the axis of the rotating shaft. Each suction cup unit is equipped with a suction nozzle. The two suction cup units can rotate synchronously with the rotating shaft in the vertical plane where they are located. The line connecting the suction nozzles at corresponding positions of the two suction cup units is parallel to the axis of the rotating shaft.

[0009] In the aforementioned flipping mechanism applicable to flipping thin workpieces, the suction nozzle picks up the workpiece to be flipped from top to bottom or from bottom to top. When the suction nozzle picks up the workpiece to be flipped from top to bottom, the position of the suction nozzle and the position of the workpiece to be flipped are initially located on opposite sides of the base. When the suction nozzle picks up the workpiece to be flipped from bottom to top, the position of the suction nozzle and the position of the workpiece to be flipped are initially located on the same side of the base.

[0010] In the above-mentioned flipping mechanism applicable to flipping thin workpieces, two suction cup units can move along the axial direction of the rotating shaft, and a locking part is provided at the end of each suction cup unit connected to the rotating shaft to lock the current position of the suction cup unit on the rotating shaft.

[0011] In the aforementioned flipping mechanism applicable to flipping thin workpieces, a recess is provided on the rotating shaft, and the length direction of the recess is consistent with the axial direction of the rotating shaft. The suction cup unit includes a protrusion that is inserted into the recess, and the circumferential degree of freedom of the suction cup unit on the rotating shaft is limited by the insertion and engagement of the recess and the protrusion.

[0012] In the above-mentioned flipping mechanism applicable to flipping thin workpieces, the recess is a groove, which is set on the rotating shaft along the axial direction of the rotating shaft, and the protrusion is a limiting post, wherein the limiting post is inserted into the groove.

[0013] In the above-mentioned flipping mechanism applicable to flipping thin workpieces, the suction cup unit includes a collar sleeved on the rotating shaft, and a locking part is provided on the collar; a connecting rod, one end of which is connected to the collar by a fastener, and a suction nozzle is provided at the other end of the connecting rod, wherein a protrusion is provided on the end of the connecting rod connected to the collar.

[0014] In the aforementioned flipping mechanism applicable to flipping thin workpieces, a through hole is provided on the collar to nest with the rotating shaft, and a gap connected to the through hole is provided along the radial direction of the collar, wherein the size of the gap is changed by rotating the locking part.

[0015] In the aforementioned flipping mechanism applicable to flipping thin workpieces, two suction cup rods are provided at the end of the connecting rod away from the collar, and each suction cup rod is connected to the connecting rod through a bracket. Each suction cup rod can move along the length of the connecting rod, and a suction nozzle is provided at one end of the suction cup rod.

[0016] In the above-mentioned flipping mechanism applicable to flipping thin workpieces, a first strip groove is provided on the connecting rod along the length direction, and the end of the suction cup rod away from the suction nozzle is inserted into the first strip groove. The bracket is L-shaped, and one end of the bracket is inserted and fixed to the suction cup rod, while the other end of the bracket is locked to the connecting rod.

[0017] In the aforementioned flipping mechanism applicable to flipping thin workpieces, a second strip groove is provided on the connecting rod along its length, and one end of the bracket is locked on the second strip groove. When the locking between the bracket and the connecting rod is released, the suction cup rod can move along the first strip groove relying on the bracket. At this time, the second strip groove serves as a guide for the movement of the suction cup rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The present invention provides a flipping mechanism suitable for flipping thin workpieces. It achieves 180° flipping of thin workpieces by means of suction cups, which will not cause deformation of thin workpieces or cause them to fall, thereby improving the reliability of flipping thin workpieces.

[0020] (2) Since both suction cup units can move along the axis of the rotating shaft, the relative distance between the two suction cup units can be adjusted, thereby adapting to the flipping of workpieces of different sizes along the axis of the rotating shaft.

[0021] (3) Since the suction cup unit is nested with the rotating shaft, the degree of freedom of the suction cup unit along the radial direction of the rotating shaft is limited, which avoids the suction cup unit from shaking when it rotates with the rotating shaft, thereby improving the stability of thin workpieces during the flipping process.

[0022] (4) Since the two suction cup rods can move along the length of the connecting rod, the relative distance between the two suction cup rods can be adjusted, thereby adapting to the flipping of workpieces of different sizes along the length of the connecting rod. Attached Figure Description

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figures 1 to 3 As shown, this utility model provides a flipping mechanism suitable for flipping thin workpieces, located between two adjacent workstations, used to flip a workpiece at one workstation by 180° and place it at the other workstation, comprising:

[0032] The base 100 serves as the supporting structure for the flipping mechanism;

[0033] The flipping assembly 200 is mounted on the base 100. The flipping assembly 200 includes a rotating shaft 210 and two suction cup units 220 are arranged side by side along the axis of the rotating shaft 210. Each suction cup unit 220 is provided with a suction nozzle 2251. The two suction cup units 220 can rotate synchronously with the rotating shaft 210 in the vertical plane where they are located. The line connecting the suction nozzles 2251 at corresponding positions of the two suction cup units 220 is parallel to the axis of the rotating shaft 210.

[0034] It is worth mentioning that the suction nozzle 2251 picks up the workpiece to be flipped from top to bottom at the workstation, at which point the suction nozzle 2251 is above the workpiece. Then it rotates in the opposite direction to place the flipped workpiece on another workstation, at which point the suction nozzle 2251 is below the workpiece. Alternatively, the suction nozzle 2251 picks up the workpiece to be flipped from bottom to top at the workstation, at which point the suction nozzle 2251 is below the workpiece. Then it continues to rotate in the same direction to place the flipped workpiece on another workstation, at which point the suction nozzle 2251 is above the workpiece.

[0035] This utility model provides a flipping mechanism suitable for flipping thin workpieces. It achieves 180° flipping of thin workpieces by adsorption, which will not cause deformation of the thin workpieces or cause them to fall, thereby improving the reliability of flipping thin workpieces.

[0036] Furthermore, when the suction nozzle 2251 picks up the workpiece to be flipped from top to bottom, in the initial state, the position of the suction nozzle 2251 and the position of the workpiece to be flipped are located on opposite sides of the base 100; when the suction nozzle 2251 picks up the workpiece to be flipped from bottom to top, in the initial state, the position of the suction nozzle 2251 and the position of the workpiece to be flipped are located on the same side of the base 100.

[0037] Preferably, the two suction cup units 220 can move along the axial direction of the rotating shaft 210 to change the relative distance between the two suction cup units 220, and a locking part 221 is provided at the end of each suction cup unit 220 connected to the rotating shaft 210 to lock the current position of the suction cup unit 220 on the rotating shaft 210.

[0038] In this embodiment, since both suction cup units 220 can move along the axial direction of the rotating shaft 210, the relative distance between the two suction cup units 220 can be adjusted, thereby adapting to the flipping of workpieces of different sizes along the axial direction of the rotating shaft 210.

[0039] More preferably, the rotating shaft 210 is provided with a recess 211, and the length direction of the recess 211 is consistent with the axial direction of the rotating shaft 210. The suction cup unit 220 includes a protrusion 222 that is inserted into the recess 211. The insertion and engagement of the recess 211 and the protrusion 222 limits the circumferential degree of freedom of the suction cup unit 220 on the rotating shaft 210, so that the suction cup unit 220 can rotate synchronously with the rotating shaft 210 when the rotating shaft 210 rotates.

[0040] It is worth mentioning that the positions of the recess 211 and the protrusion 222 can be interchanged. That is, the protrusion 222 is set on the rotating shaft 210, and the length direction of the protrusion 222 is consistent with the axial direction of the rotating shaft 210. The corresponding recess 211 is set on the suction cup unit 220. Similarly, the circumferential degree of freedom of the suction cup unit 220 on the rotating shaft 210 can be limited by the insertion and cooperation between the protrusion 222 and the recess 211.

[0041] Furthermore, the recess 211 is a groove, which is set on the rotating shaft 210 along the axial direction of the rotating shaft 210, and the protrusion 222 is a limiting post, wherein the limiting post is inserted into the groove.

[0042] More preferably, the suction cup unit 220 includes a collar 223 sleeved on the rotating shaft 210, and a locking part 221 disposed on the collar 223; a connecting rod 224, one end of which is connected to the collar 223 by a fastener, and a suction nozzle 2251 disposed on the other end of the connecting rod 224, wherein a protrusion 222 is disposed on the end of the connecting rod 224 connected to the collar 223.

[0043] It is worth mentioning that, since the suction cup unit 220 is nested with the rotating shaft 210, the degree of freedom of the suction cup unit 220 along the radial direction of the rotating shaft 210 is limited, so as to avoid the suction cup unit 220 shaking when rotating with the rotating shaft 210, thereby improving the stability of thin workpieces during the flipping process.

[0044] More preferably, the collar 223 is provided with a through hole 2231 that nests with the rotating shaft 210, and a gap 2232 communicating with the through hole 2231 is provided along the radial direction of the collar 223. By providing the gap 2232, the collar 223 has a deformation function. The size of the gap 2232 is changed by rotating the locking part 221, thereby locking the connection between the suction cup unit 220 and the rotating shaft 210, or releasing the lock between the suction cup unit 220 and the rotating shaft 210.

[0045] It is worth mentioning that the locking part 221 is a hand-tightening screw that can be manually turned to lock or unlock, and an anti-loosening handle is provided on the hand-tightening screw. When the collar 223 is locked with the rotating shaft 210, pressing down the anti-loosening handle can further lock the connection between the collar 223 and the rotating shaft 210.

[0046] Preferably, two suction cup rods 225 are provided on the end of the connecting rod 224 away from the collar 223, and each suction cup rod 225 is connected to the connecting rod 224 through a bracket 226. Each suction cup rod 225 can move along the length of the connecting rod 224 to change the relative distance between the two suction cup rods 225, and a suction nozzle 2251 is provided at one end of the suction cup rod 225.

[0047] In this embodiment, since the two suction cup rods 225 can move along the length direction of the connecting rod 224, the relative distance between the two suction cup rods 225 can be adjusted, thereby adapting to the flipping of workpieces of different sizes along the length direction of the connecting rod 224.

[0048] More preferably, the connecting rod 224 is provided with a first strip groove 2241 along its length, and one end of the suction cup rod 225 away from the suction nozzle 2251 is inserted into the first strip groove 2241. The bracket 226 is L-shaped, and one end of the bracket 226 is inserted and fixed to the suction cup rod 225, while the other end of the bracket 226 is locked to the connecting rod 224.

[0049] More preferably, a second strip groove 2242 is provided on the connecting rod 224 along its length, and one end of the bracket 226 is locked on the second strip groove 2242. When the locking between the bracket 226 and the connecting rod 224 is released, the suction cup rod 225 can move along the first strip groove 2241 by relying on the bracket 226. At this time, the second strip groove 2242 serves as a guide for the movement of the suction cup rod 225.

[0050] Preferably, the base 100 is arranged in a U-shape, and the flipping component 200 includes a motor 230, and the rotating shaft 210 is connected to the two ends of the output end of the motor 230. The two ends of the rotating shaft 210 are rotatably connected to the two sides of the open end of the base 100 through bearings.
