Description

Technical Field

[0001] This invention relates to the field of glass handling technology, and more specifically to a glass substrate handling device. Background Technology

[0002] Modern large-scale glass substrate production is flexible and diverse. Manufacturers can produce glass substrates of different sizes according to customer requirements to adapt to the pace of modern production. Traditional glass handling suction cups have a fixed stroke. When the glass is too large, the suction area is insufficient and stress is easily generated, which may cause damage during the handling process. In severe cases, it may even destroy the glass substrate.

[0003] In the prior art, glass substrates are generally transported using specific handling devices. For example, a glass substrate handling device disclosed in CN113479648B includes a support assembly. Angle limiting components are symmetrically installed on the top of the support assembly, and guide rail assemblies are symmetrically installed on the left and right sides of the support assembly. A travel limiting component is installed on the guide rail assembly. The support assembly includes a support cross seat and a rotating block. Rotation clearance grooves are opened on the front and rear sides of the support cross seat, and rotation through holes are opened in the rotation clearance grooves. A handle is fixedly connected to the middle of the top of the support cross seat.

[0004] This type of glass handling device can only rotate the suction cups, but cannot flexibly adjust the distance between them. When handling large glass substrates, suction cups that are too close together will result in insufficient suction force, making it impossible to handle the glass substrates smoothly. The inability to adjust the distance makes the device unsuitable for large glass substrates, thus limiting its applicability. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the devices in the background art cannot be applied to large-sized glass substrates, thus affecting the applicable scenarios and scope, and to propose a glass substrate handling device.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-5 As shown, this invention is a glass substrate handling device, including a handling frame 1. A handle 11 is located at the top center of the handling frame 1. Adjustment grooves 12 are located on both sides of the handling frame 1, arranged along a horizontal plane and symmetrically about the central plane of the handling frame 1. Limiting grooves 13 are located on the top surfaces of both sides of the handling frame 1, communicating with the corresponding adjustment grooves 12 below. The limiting grooves 13 are symmetrically arranged about the central plane. A movable structure 2 is provided within each of the two adjustment grooves 12, with a movable plate 21 slidably connected within the two adjustment grooves 12. Adjustment structures 3 are located on both sides of the movable plate 21, with adjustment plates 31 disposed on both sides of each movable plate 21. A slot is located at the center of each adjustment plate 31, separating each adjustment plate 31 into two pieces. An adjustment slot 32 is located on the opposite side of each of the two adjustment plates 31, and an adjustment post 33 extending along the direction of the adjustment plate 31 is located inside the slot.

[0035] Each adjusting column 33 is slidably equipped with an adsorption structure 4, and a sliding column 41 passes through the adsorption structure 4. Each sliding column 41 is slidably connected to the surface of the corresponding adjusting column 33. Each sliding column 41 is arranged vertically, and limit posts 42 are provided on both sides of the circumferential surface of the sliding column 41. The limit posts 42 are positioned above the adjusting plate 31, and the bottom surface of the limit posts 42 can contact the top surface of the adjusting plate 31. This allows the limit posts 42 to limit the sliding of the sliding column 41. Each sliding column 41 has a suction cup 44 on its bottom surface.

[0036] The top surfaces of the movable structures 2 on both sides of the transport frame 1 are equipped with fixed structures 5, which are connected by limiting grooves 13 on both sides of the transport frame 1. Sliding platforms 58 are slidably mounted on the top surfaces of both sides of the transport frame 1. Each sliding platform 58 has two connecting plates 22 on its bottom surface, and the bottom of the two connecting plates 22 is fixedly connected to the top surface of the lower movable plate 21. A setting platform 55 is fixedly mounted on the top surface of each sliding platform 58. The inner cavities of the sliding platform 58 and the setting platform 55 are connected. Both the sliding platform 58 and the setting platform 55 have identical circular setting grooves 510 and square positioning grooves 511. The downward projections of the positioning grooves 511 and setting grooves 510 in the sliding platform 58 and the setting platform 55 coincide. Connecting columns 52 are slidably mounted within the setting grooves 510 of the sliding platform 58 and the setting platform 55. Transmission blocks 53 are mounted on the surface of the connecting columns 52, located within the positioning grooves 511. Magnetic plates 54 are mounted on both sides of the connecting columns 52. A transmission frustum 51 is provided on the top surface of the connecting column 52, and the radius of the transmission frustum 51 gradually decreases from top to bottom. Connecting brackets 56 are provided on both sides of the setting platform 55, and the two ends of the connecting brackets 56 extend upwards and are provided with limiting sleeves 57, the inner cavity of the limiting sleeves 57 being arranged horizontally. Movable uprights 59 are detachably provided on both sides of the sliding platform 58 and the setting platform 55. The movable uprights 59 are U-shaped, and openings are provided on both sides of the sliding platform 58, communicating with the setting grooves 510 of the sliding platform 58. One end of the movable upright 59 can extend into the opening and contact the magnetic sheet 54 on the surface of the connecting column 52. The other end of the movable upright 59 can extend into the limiting sleeve 57, with the end near the transmission sleeve inclined, and the inclination angle of one section of the movable upright 59 adapting to the inclination of the surface of the transmission frustum 51. The lower sliding plate has an insertion groove 23 and a square transmission groove 24 on its surface. The downward projection of the setting groove 510 and the positioning groove 511 coincides with the insertion groove 23 and the transmission groove 24. An electromagnetic switch is installed inside the insertion groove 23. The electromagnetic switch controls the sliding of the moving plate 21. When the electromagnetic switch is closed, the sliding plate is fixed inside the adjustment groove 12.

[0037] When using this glass substrate handling device, the glass substrate to be handled is placed below the handling device. The distance between the four suction cups 44 is then adjusted by sliding the sliding post 41 on the surface of the sliding adjustment post 33, causing the suction cups 44 to adhere to the surface of the glass substrate. When the distance between the suction cups 44 needs adjustment, pressing the transmission platform 51 causes the connecting post 52 to press down, thus extending the lower part of the connecting post 52 into the insertion groove 23. The transmission block 53 on the surface of the connecting post 52 extends into the transmission groove 24, and the magnetic plates 54 on both sides of the connecting post 52 enter the insertion groove 23, activating the electromagnetic switch inside the insertion groove 23, thereby releasing the moving plate 21 from its fixed position. Pressing the transmission platform 51 moves the lower moving plate 21, and simultaneously, rotating the transmission platform 51 by the rotating block 512 causes the transmission block 53 at the bottom of the transmission platform 51 to engage with the transmission groove 24 of the moving plate 21, causing the moving plate 21 to rotate and changing the position of the suction cups 44 on both sides of the moving plate 21. During the pressing of the transmission frustum 51, the surface of the transmission frustum 51 contacts the movable uprights 59 on both sides, and the movable uprights 59 are squeezed and pop out within the limiting sleeve 57. At the same time, the connecting column 52 slides down, causing the magnetic piece 54 to disengage from the other end of the movable upright 59, allowing the movable upright 59 to automatically pop out when the transmission frustum 51 is pressed. After the position is determined, the transmission frustum 51 is lifted by pinching the rotating block 512, causing the bottom end of the connecting column 52 to disengage from the moving plate 21, and the electromagnetic switch of the moving plate 21 is closed and relatively fixed in the adjusting groove 12. Then, the movable uprights 59 on both sides are inserted back into the sliding table 58, the bottom end of the movable upright 59 is attracted to the magnetic piece 54 on the surface of the connecting column 52, and the other end contacts the surface of the transmission frustum 51, thereby fixing the transmission frustum 51 and the connecting column 52 and preventing them from falling.

[0038] Example 2

[0039] The present invention discloses a method for using a glass substrate handling device, comprising the following steps:

[0040] Step 1: Place the glass substrate to be transported under the transport device. Then, adjust the distance between the four suction cups 44 by sliding the sliding column 41 on the surface of the sliding adjustment column 33, so that the suction cups 44 adsorb onto the surface of the glass substrate;

[0041] Step 2: When adjusting the distance of the suction cup 44, press the transmission platform 51. The transmission platform 51 drives the connecting column 52 to press down, so that the bottom of the connecting column 52 extends into the insertion groove 23. The transmission block 53 on the surface of the connecting column 52 extends into the transmission groove 24. The magnetic pieces 54 on both sides of the connecting column 52 enter the insertion groove 23, activating the electromagnetic switch inside the insertion groove 23, thereby releasing the fixation of the moving plate 21.

[0042] Step 3: Pressing the transmission platform 51 can drive the lower moving plate 21 to move. At the same time, the transmission platform 51 can be rotated by the rotating block 512. The transmission block 53 at the bottom of the transmission platform 51 engages with the transmission groove 24 of the moving plate 21 to drive the moving plate 21 to rotate, thereby changing the position of the suction cups 44 on both sides of the moving plate 21.

[0043] Step 4: During the pressing of the transmission frustum 51, the surface of the transmission frustum 51 contacts the movable uprights 59 on both sides, and the movable uprights 59 are squeezed and pop out inside the limiting sleeve 57. At the same time, the connecting column 52 slides down, causing the magnetic piece 54 to disengage from the other end of the movable upright 59, so that the movable upright 59 automatically pops out when the transmission frustum 51 is pressed.

[0044] Step 5: By pinching the rotating block 512, the transmission frustum 51 is lifted, causing the bottom end of the connecting column 52 to detach from the moving plate 21. The electromagnetic switch of the moving plate 21 is closed, and it is relatively fixed in the adjusting groove 12. Then, the moving uprights 59 on both sides are inserted back into the sliding table 58. The bottom end of the moving upright 59 is attracted to the magnetic sheet 54 on the surface of the connecting column 52, and the other end is in contact with the surface of the transmission frustum 51, thereby fixing the transmission frustum 51 and the connecting column 52 and preventing them from falling.

[0045] The working principle of this invention: A glass substrate handling device of this invention includes a movable structure 2. The movable plate 21 of the movable structure 2 has suction cups 44 on both sides. The movable plate 21 can move within an adjustment groove 12, thereby adjusting the distance between the suction cups 44, making this glass substrate handling device suitable for glass substrates of various sizes. A fixed structure 5 is provided, with a sliding table 58 and a setting table 55 on the top surface of each movable plate 21. By pressing the top transmission frustum 51, the connecting posts 52 inside the sliding table 58 and setting table 55 move into the insertion groove 23, and the surface of the connecting posts 52... The magnetic sheet 54 can activate the electromagnetic switch of the movable plate 21, and the connecting column 52 can drive the movable plate 21 to move and rotate. By setting the movable upright 59, by pulling the transmission platform 51 and the connecting column 52 upward, the movable upright 59 on both sides is extended into the sliding table 58. One end of the movable upright 59 is attracted to the magnetic sheet 54 on the surface of the connecting column 52, and the other end is in contact with the surface of the transmission platform 51, thereby fixing the connecting column 52 to prevent it from falling. When the transmission platform 51 is pressed, the magnetic sheet 54 is released from one end of the movable upright 59 and the transmission platform 51 releases the pressure on the other end of the movable upright 59, causing it to automatically detach.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
