Description

Technical Field

[0001] This invention relates to a glass substrate cantilever clamping device, belonging to the technical field of suspension conveying devices. Background Art

[0002] Stable clamping and transport of glass substrates are crucial in the production, processing, and transportation of glass substrates. Existing glass substrate clamping devices suffer from several problems. Some devices are complex in structure and occupy a large space, resulting in an inefficient production line layout and increased equipment costs and space requirements. Others are cumbersome and inefficient in handling glass substrates, failing to meet the demands of rapid loading and unloading in large-scale production. Furthermore, during the transfer and transport of glass substrates, existing clamping devices struggle to ensure stable clamping, easily leading to loosening and damage from drops, severely impacting production efficiency and product quality. Therefore, developing a compact, quick-access, and stable glass substrate clamping device is of significant practical importance. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a glass substrate cantilever clamping device with a compact structure and quick loading and unloading.

[0004] The glass substrate cantilever clamping device of this invention includes a cantilever frame with multiple sets of vertically parallel clamping plates. The clamping plates are connected to the cantilever frame via connecting rods, forming a parallelogram linkage mechanism. When not clamping, the clamping plates are at their lowest travel points, with the two clamping plates in the same group being closest to each other at their lowest points, the closest distance being less than the thickness of the glass substrate. During clamping, the glass substrate is vertically inserted from bottom to top. The two clamping plates in the group are gradually separated as they are pushed upwards by the glass substrate. After the glass substrate is placed between the two clamping plates, it contacts the clamping surfaces on its inner sides. After release, the glass substrate, under its own weight, pulls the two clamping plates in the group downwards and converges towards the center to clamp, achieving stable clamping of the glass substrate. The cantilever clamping device can circulate under the drive of a transfer and conveying mechanism to transport (or buffer) the glass substrate.

[0005] Preferably, when the clamping plate is at the lowest point of its stroke, the connecting rod is in a horizontal state, at which point the distance between the two clamping plates in the same group is the closest.

[0006] The glass substrate cantilever clamping device of the present invention is equipped with a clamping release mechanism, which is used to release the clamping of the glass substrate during material removal, so that the glass substrate falls.

[0007] Specifically, a connecting curved plate is provided above the clamping plate, and a transverse roller is installed at the top of the connecting curved plate; the clamping release mechanism includes a wedge that can slide along the length of the cantilever frame, the wedge is located below the roller and its upper surface is lower at one end and higher at the other; when the wedge moves, the roller rolls along the upper surface of the wedge, which can force the roller to drive the clamping plate to move up and open to both sides at the same time, releasing the clamping.

[0008] Furthermore, the upper surface of the wedge is provided with several parallel needle rollers, the axis of which is perpendicular to the axis of the roller. As the roller drives the clamping plate upwards and opens to both sides, movement occurs between the roller and the wedge along the roller axis. The arrangement of the needle rollers reduces the frictional force of the roller's axial movement, making the mechanism operate smoothly.

[0009] Preferably, each clamp is equipped with a wedge, and all wedges are connected together by a linkage frame and move synchronously.

[0010] Furthermore, the linkage frame is equipped with a push-pull handle at its outer end and an abutment shaft at its inner end. When the linkage frame moves inward, it drives the wedge block to move inward synchronously to release the clamping. During the operation of the cantilever clamping module, the abutment shaft cannot extend due to the obstruction of other components (such as tracks), which can limit the movement of the linkage frame inward and achieve self-locking during transportation. This prevents accidental release of the clamping in areas outside the loading and unloading stations, which could cause the glass substrate to fall and be damaged.

[0011] Preferably, the lower end of the assembled clamps is flared to facilitate material loading.

[0012] Preferably, the clamping surface on the inner side of the clamping plate is provided with a rubber pad to increase the clamping friction.

[0013] The beneficial effects of this invention compared to the prior art are: 1) Compact structure: The invention adopts a cantilever frame and parallelogram linkage mechanism design, which makes the overall structure simple, occupies little space, and is easy to lay out and install on the production line, effectively saving space and reducing equipment costs.

[0014] 2) Quick Loading and Unloading: Thanks to its unique clamping design, the glass substrate can be automatically clamped simply by being placed vertically from bottom to top, eliminating the need for complex operating procedures and greatly improving loading and unloading efficiency to meet the demands of rapid operation in large-scale production. Simultaneously, the equipped clamping release mechanism allows for quick release of the clamp by pushing the linkage frame, enabling the glass substrate to fall smoothly, further enhancing the convenience of loading and unloading the glass substrate.

[0015] 3) Stable clamping: The clamping is achieved using the weight of the glass substrate itself. When the glass substrate is placed between the two clamping plates, its own weight pulls the clamping plates downwards and towards the center, forming a stable clamping state. The rubber pads on the inner side of the clamping plates increase the clamping friction, further ensuring the reliability of the clamping and effectively preventing the glass substrate from slipping during transportation.

[0016] 4) Self-locking during transport: The abutment shaft set at the inner end of the linkage frame cannot extend under the obstruction of the track of the transport mechanism, realizing the self-locking function during transportation. This prevents the glass substrate from falling and being damaged due to accidental release of clamping in areas outside the loading and unloading stations, thus improving the safety and stability of the equipment.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] The description of the present invention is merely a structural or even functional description of the embodiments, and the scope of the present invention is not limited by the embodiments described herein.

[0021] like Figures 1-12 As shown, this embodiment is achieved through the following technical solution: a glass substrate cantilever clamping device includes a cantilever frame 8, with a hollowed-out middle area for the glass substrate 15 to pass through. The cantilever frame 8 is provided with multiple sets of vertically parallel clamping plates 9. The clamping plates 9 are connected to clamping plate seats 6 fixed to the bottom surface of the cantilever frame 8 via connecting rods 5. The clamping plates 9, clamping plate seats 6, and connecting rods 5 form a parallelogram linkage mechanism. Each set of clamping plates 9 can be opened and closed, and the clamping plates 9 remain vertical and parallel to each other during the opening and closing process. The clamping plates 9 in the same set can achieve symmetrical synchronous opening and closing through the meshing of a pair of gears (or half-tooths) (not shown in the figure).

[0022] When not clamped, clamping plate 9 is at its lowest point of travel, at which point connecting rod 5 is in a horizontal state, such as... Figure 9 As shown. The two plates 9 in the same group are closest to each other, and the closest distance is less than the thickness of the glass substrate 15.

[0023] During clamping, the glass substrate 15 is vertically inserted from bottom to top. The two clamping plates 9 are pushed upwards by the glass substrate 15 and gradually separate. After the glass substrate 15 is placed between the two clamping plates 9, it contacts its inner clamping surface. After release, the glass substrate 15, under its own weight, pulls the two clamping plates 9 downwards and converges towards the center to clamp, achieving stable clamping of the glass substrate 15 (at this time, the angle α between the connecting rod 5 and the horizontal direction is ≤20°). The lower end of the clamping plates 9 has a flared opening 16 for easy loading; the inner clamping surface of the clamping plates 9 is provided with a rubber pad to increase clamping friction.

[0024] The present invention is equipped with a clamping release mechanism, which is used to release the clamping of the glass substrate 15 during material removal, so that the glass substrate 15 falls.

[0025] A connecting curved plate 10 is provided above the clamping plate 9, and a transverse roller 11 is installed at the top of the connecting curved plate 10 for cooperating with the aforementioned clamping release mechanism. Specifically, the clamping release mechanism includes a wedge 4 mounted on the guide rail 2 and slidable along the length of the cantilever frame 8. Each clamping plate 9 is equipped with one wedge 4, and all wedges 4 are connected together by a linkage frame 3 and move synchronously. The wedge 4 is located below the roller 11, with one end of its upper surface lower than the other. Several parallel roller needles 13 are arranged on the upper surface of the wedge 4, and the axis of the roller needles 13 is perpendicular to the axis of the roller 11. When the wedge 4 moves, the roller 11 rolls along the upper surface of the wedge 4, which can force the roller 11 to move the clamping plate 9 upward and open it to both sides at the same time, releasing the clamp. During the process of the roller 11 moving the clamping plate 9 upward and opening it to both sides, there will be movement between the roller 11 and the wedge 4 along the axis of the roller 11. The arrangement of the roller needles 13 can reduce the friction of the axial movement of the roller 11, making the mechanism move smoothly.

[0026] The linkage frame 3 is provided with a push-pull handle 7 at the outer end and an abutment shaft 12 at the inner end. When the linkage frame 3 moves inward, it drives the wedge block 4 to move inward synchronously to release the clamping. The linkage frame 3 is equipped with an elastic mechanism 1. The elastic mechanism 1 causes the linkage frame 3 to move outward, which can reset the linkage frame 3.

[0027] The glass substrate cantilever clamping device can circulate under the drive of the transfer mechanism to transport (or buffer) glass substrates. During operation, the abutment shaft 12 is blocked by the track of the transfer mechanism and cannot extend, thus restricting the inward movement of the linkage frame 3 and achieving self-locking clamping. The tracks at corresponding positions of the loading and unloading stations have concave notches to allow the abutment shaft 12 to move inward at these stations, releasing the clamp on the glass substrate 15 for loading and unloading. A transverse roller 14 is provided at the end of the abutment shaft 12 to prevent rigid friction between the abutment shaft 12 and the track.

[0028] The working process or principle of this invention: The glass substrate 15 is vertically placed into the glass substrate cantilever clamping device from bottom to top. The two clamping plates 9 are pushed upwards by the glass substrate 15 and gradually separate, with the glass substrate 15 positioned between the two clamping plates 9 and in contact with the inner rubber pads. The glass substrate 15 is released, and under its own weight, it pulls the two clamping plates 9 downwards and converges to clamp them tightly, achieving stable clamping of the glass substrate 15. The glass substrate 15 can be buffered or transported in a transfer mechanism.

[0029] When unloading, the receiving device comes to the bottom of the glass substrate 15 and contacts the bottom surface of the glass substrate 15. Pushing the push-pull handle 7 causes the linkage frame 3 to move inward, which in turn drives the wedge block 4 to move inward synchronously. The roller 11 rolls along the upper surface of the wedge block 4, which can force the roller 11 to move the clamping plate 9 upward and open to both sides at the same time, releasing the clamping of the glass substrate 15, and the glass substrate 15 falls into the receiving device.

[0030] During operation, the abutment shaft 12 cannot extend due to the obstruction of the transfer mechanism, which restricts the movement of the linkage frame 3 inward and achieves self-locking during transfer clamping. The tracks at the corresponding positions of the loading and unloading stations have concave notches, which allow the abutment shaft 12 to move inward at the loading and unloading stations, releasing the clamping of the glass substrate 15 for loading and unloading.

[0031] Of course, the above description is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is also not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of the present invention should fall within the patent coverage of the present invention.
