Description

Technical Field

[0001] This invention relates to a parallel clamping and lifting device for quartz glass ingots, which is particularly suitable for clamping and shifting block glass ingots and belongs to the technical field of mechanical handling equipment. Background Technology

[0002] Synthetic quartz glass is a new material used in important fields such as optics, semiconductors, and aerospace. With the rapid development of these fields, the demand for automated handling of bulk synthetic quartz glass ingots in processes such as drawing, annealing, cutting, and storage continues to grow. These workpieces are characterized by their large size, smooth surface, brittle edges, and high cleanliness requirements. Furthermore, there is a diversity in the specifications, processes, and handling requirements of bulk synthetic quartz glass ingots. Currently used adsorption and lifting equipment is difficult to adapt to the clamping and handling requirements in these situations. The manual binding and handling methods used are not only inconvenient and time-consuming, but also pose safety hazards to personnel and risks of workpiece damage. Although various types of clamping robots exist, their structures and clamping methods are not entirely reasonable, resulting in poor stability and reliability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a parallel clamping and lifting device for quartz glass ingots, which is not only suitable for clamping and lifting of block glass ingots in various process stages, but also has stable and reliable performance.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problems is as follows: it includes a connecting plate, a scissor lift telescopic mechanism connected below the connecting plate, and a rotating parallel clamping device connected to the lower end of the scissor lift telescopic mechanism.

[0005] According to the above scheme, the scissor link telescopic mechanism includes scissor links symmetrically arranged on both sides. The middle of the scissor links on both sides is hinged to the intermediate shaft. The upper ends of the scissor links are respectively hinged to the connecting plate through two corresponding hinged links. The lower ends of the scissor links are respectively hinged to the upper end of the rotating clamping device through two corresponding hinged links. An upper and lower telescopic drive component is fixedly installed in the middle of the connecting plate. The telescopic rod of the upper and lower telescopic drive component is hinged to the intermediate shaft, driving the scissor link telescopic mechanism to extend and retract up and down.

[0006] According to the above scheme, the scissor link is composed of two links of equal length on each side, which are hinged together by an intermediate shaft. Each pair of links forms a section, and the scissor link consists of one or more sections of scissor link that are hinged together end to end.

[0007] According to the above scheme, the rotating parallel clamping device includes a rotating drive disk, and a parallel gripper mechanism is installed at the lower end of the rotating drive disk.

[0008] According to the above scheme, the rotary drive disk includes a connecting plate connected to the scissor lift telescopic mechanism, a fixed disk connected below the connecting plate, a rotating disk configured on the fixed disk, and a rotary drive component installed on the connecting plate. The rotary drive component is connected to the rotating disk and drives the rotating disk to rotate.

[0009] According to the above scheme, a guide rod mechanism is provided between the scissor lift telescopic mechanism and the rotary parallel clamping device. The guide rod mechanism includes guide sleeves and guide rods installed on both sides of the intermediate shaft through an intermediate connecting plate. The lower end of the guide rod is connected to the connecting plate of the rotary drive disk.

[0010] According to the above scheme, the parallel gripper mechanism includes a gripper base plate connected to the rotating disk, and parallel grippers are symmetrically arranged on both sides of the gripper base plate. The parallel grippers include at least one pair of parallelogram connecting rods arranged vertically. The upper end of the parallelogram connecting rod is connected to the gripper base plate, and the lower end of the parallelogram connecting rod is hinged to the flat plate gripper.

[0011] According to the above scheme, the two ends of the upper connecting rod of the parallelogram connecting rod are respectively hinged to the upper part of the gripper base plate and the flat plate gripper, and the two ends of the lower connecting rod are respectively hinged to the gripper base plate and the flat plate gripper at a distance and parallel downwards.

[0012] According to the above scheme, each pair of parallelogram links is arranged in two sets at a lateral interval, and at least one link in each pair of parallelogram links is a driving link, with the upper end of the driving link connected to the rotary driving component.

[0013] According to the above scheme, the inner surface of the flat plate gripper is equipped with a flexible anti-slip pad and a compressive stress sensor.

[0014] The working process of this invention is as follows: the lifting and rotating drive disk of the scissor lift linkage telescopic mechanism enables the rotating parallel clamping device to reach the work position. The block workpiece can be clamped by tightening the flat jaws. The telescopic mechanism rises to lift the clamped workpiece and simultaneously drives the running mechanism connected to the quartz glass ingot parallel clamping and lifting device to move the workpiece to the designated work position. Finally, the flat jaws are released to allow the workpiece to gently fall into place, thus completing the task of clamping and transporting the block workpiece.

[0015] The beneficial effects of this invention are as follows: 1. By setting up a scissor lift telescopic mechanism in conjunction with a rotating parallel clamping device, it is possible to realize actions such as clamping, rotating, and vertically lifting of block workpieces. When configured with a moving operating mechanism, it can be applied to the translation, handling, and repositioning of block workpieces of various specifications. 2. The clamping operation of each mechanism in this invention is stable and reliable, and the movement of the workpiece is smooth and safe. Especially considering the characteristics of block synthetic quartz glass ingots—large volume, smooth surface, brittle edges, and high cleanliness—it can fully meet the diverse requirements of their specifications, processes, and handling. 3. The rotating parallel clamping device features stable and reliable clamping and flexible and convenient rotation. When configured with a scissor lift telescopic mechanism, it can achieve precise positioning. 4. The guide rod mechanism further improves the stability of the scissor lift telescopic mechanism.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] One embodiment of the present invention is as follows: Figures 1-4As shown, the device includes a connecting plate 2, below which is connected a scissor linkage telescopic mechanism. The scissor linkage telescopic mechanism includes scissor linkages 13 symmetrically arranged on both sides. The middle of the scissor linkages on both sides is hinged to the intermediate shaft 12. The upper ends of the scissor linkages are respectively hinged to the connecting plate through two corresponding hinged connecting rods 14. The lower ends of the scissor linkages are respectively hinged to the upper end of the rotating parallel clamping device through two corresponding hinged connecting rods 11. An up-and-down telescopic drive component 1 is fixedly installed in the middle of the connecting plate. The up-and-down telescopic drive component is an electric telescopic drive component, including a motor 15 and a screw drive component. The front end of the telescopic rod of the up-and-down telescopic drive component is hinged to the intermediate shaft through an intermediate hinge seat 19, driving the scissor linkage telescopic mechanism to extend and retract up and down. The scissor linkage telescopic mechanism has the function of amplifying the travel distance of the telescopic rod. The lower end of the scissor lift telescopic mechanism is connected to a rotating parallel clamping device. The rotating parallel clamping device includes a rotating drive disk, which includes a connecting plate 6 connected to the scissor lift telescopic mechanism. A fixed disk is connected below the connecting plate, and a rotating disk 17 is disposed outside the fixed disk. A rotating drive component 18 is mounted on the connecting plate, and the rotating drive component is connected to the rotating disk via a gear set to drive the rotating disk to rotate. A parallel gripper mechanism is mounted at the lower end of the rotating drive disk. The parallel gripper mechanism includes a gripper base plate 7 connected to the rotating disk. Parallel grippers are symmetrically mounted on both sides of the gripper base plate. Each parallel gripper includes a parallelogram connecting rod mounted vertically. The upper end of the parallelogram connecting rod is connected to the gripper base plate, and the lower end of the parallelogram connecting rod is hinged to a flat gripper 10. The two ends of the upper connecting rod 8 are respectively hinged above the gripper base plate and the flat gripper, and the two ends of the lower connecting rod 9 are respectively hinged downwards at parallel intervals to the gripper base plate and the flat gripper. Each pair of parallelogram-shaped links is arranged in two sets at a lateral interval. One link in each pair is a driving link; in this embodiment, the lower link 9 is the driving link. The upper end of the driving link is connected to the rotary drive component 16, which can be a stepper motor. A flexible anti-slip pad and a compressive stress sensor are installed on the inner surface of the flat gripper.

[0023] The second embodiment of the present invention differs from the previous embodiment in that a guide rod mechanism is provided between the scissor lift telescopic mechanism and the rotary parallel clamping device. The guide rod mechanism includes guide sleeves 3 and guide rods 5 mounted on both sides of the intermediate shaft via an intermediate connecting plate 4. The lower end of the guide rod is connected to the connecting plate 6 of the rotary drive disk. This allows the scissor lift telescopic mechanism and the rotary drive disk to move more smoothly and reliably up and down.
