Description

Technical Field

[0001] This utility model belongs to the field of optoelectronic glass and relates to a vacuum adsorption transfer device for large-size optoelectronic glass. Background Technology

[0002] In the production, processing and transportation of optoelectronic glass, large-size optoelectronic glass, due to its large size, heavy weight and fragile material, places extremely high demands on the stability, safety and adaptability of the transfer device. As a key piece of equipment for optoelectronic glass transfer, the vacuum adsorption transfer device's core function is to stably grasp the glass and achieve precise transfer through vacuum adsorption force, thereby improving production efficiency, reducing manual intervention and lowering the glass breakage rate.

[0003] The patent application number 202122050274.X, entitled "A Glass Transfer Device", discloses a glass transfer device including a frame, a tray, an adsorption mechanism, a transfer mechanism and a lifting mechanism. It uses multiple vacuum suction cups arranged in an array and whose positions are adjustable to ensure that large pieces of glass are transferred smoothly between a scribing machine and a breaking machine.

[0004] The aforementioned "glass transfer device" has the following problems: In the scenario of transferring large-size optoelectronic glass, if the vacuum adsorption system has insufficient adsorption force due to equipment aging or wear of seals, or if it encounters a sudden air leak during transportation, and there is a lack of additional protective measures, the large-size optoelectronic glass will fall off the transfer device. Its fall will damage the surrounding production equipment, and since there are operators below, it will also pose a threat to their lives. Summary of the Invention

[0005] The technical problem this utility model aims to solve is that in the scenario of transferring large-size optoelectronic glass, if the vacuum adsorption system suffers from insufficient adsorption force due to equipment aging or wear of seals, or if a sudden air leak occurs during transportation, and there is a lack of additional protective measures, the large-size optoelectronic glass will fall from the transfer device. This fall will damage surrounding production equipment, and the safety of personnel operating below will be threatened. A vacuum adsorption transfer device for large-size optoelectronic glass includes a crossbeam frame. Support frames are welded and installed on the lower surfaces of both ends of the crossbeam frame. An electric push rod is fixedly installed on the upper surface of the support frame. The working end of the electric push rod passes through the crossbeam frame and is fixedly installed with a slide rail. A guide rod is fixedly installed in a groove on the inner surface of the support frame. The two ends of the slide rail are slidably connected to the outer surfaces of the two guide rods. Two sliders are slidably installed on the inner surface of the slide rail. A connecting plate is fixedly installed on the lower surface of each of the two sliders. A buffer unit is provided on the lower surface of each of the two connecting plates to buffer the optoelectronic glass during adsorption.

[0006] The buffer unit includes four hydraulic rods, which are located at the four corners of the lower surface of the two connecting plates. Each of the four hydraulic rods has a suction cup at its other end. The outer surface of the suction cup is provided with a lifting unit for preventing the photoelectric glass from falling and for protection during adsorption and transportation.

[0007] The lifting unit includes two electric push rods and a support plate. There are three electric push rods, and a support plate is fixedly installed at the working end of each of the three electric push rods. The three support plates drive one electric push rod to support the photoelectric glass.

[0008] The suction cup of this invention has a double-headed electric threaded rod II fixedly installed on its upper surface. Both working ends of the double-headed electric threaded rod II are threaded with slide rod I. Two limiting rings I are symmetrically welded and installed on the upper surface of the suction cup. The two slide rods I are slidably connected in the limiting rings I respectively.

[0009] Limiting rings 2 are welded and installed at the four corners of the upper surface of the suction cup of this utility model. A sliding rod 2 is slidably installed in one of the limiting rings 2, and a crossbar is welded and installed at the other end of the two sliding rods 2 and the sliding rod 1.

[0010] In this invention, the three electric push rods are respectively installed in the grooves opened on the outer surface of one slide rod and two slide rods.

[0011] A partition plate is welded and installed on the outer surface of the hydraulic rod of this utility model, and a spring is sleeved on the working end of the hydraulic rod.

[0012] The adjustment unit of this utility model includes a double-headed electric threaded rod, which is fixedly installed on the inner surface of the slide rail, and the two sliders are respectively installed on the two working ends of the double-headed electric threaded rod.

[0013] Two casters are installed on the lower surface of each of the two support frames of this invention.

[0014] Working process or working principle: By starting the double-headed electric screw rod, the two sliders slide relative to each other on the slide rail, so that the two sliders drive the two suction cups to move to the length that matches the photoelectric glass. Then, the electric push rod is started to move the slide rail downward, thereby moving the suction cups downward.

[0015] As the suction cup moves downward, the suction nozzle contacts the upper surface of the photoelectric glass. To ensure that the suction nozzle makes tight contact with the upper surface of the photoelectric glass, the suction cup continues to move downward. The hydraulic rod and spring work together to cushion the impact. After the suction is complete, the electric push rod is activated to lift the photoelectric glass to 50 centimeters above the ground.

[0016] Start the double-headed electric threaded rod 2 to drive the slide rod 1, the two slide rods 2 and the crossbar to slide inward. Then start the three electric push rods 2 to drive the tray with rubber pads on the surface to stick tightly to the lower surface of the photoelectric glass. Then start the electric push rod 1 to lift the photoelectric glass for transportation and transfer.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Firstly, a lifting unit is added to the outside of the suction cup. The double-headed electric threaded rod drives the slide rod one, slide rod two and crossbar in linkage. Together with the electric push rod two, the support plate is moved to stick tightly to the lower surface of the glass, forming a double fixing structure of vacuum adsorption and mechanical lifting. Even if the vacuum adsorption force suddenly fails, the support plate can hold the glass in time, thereby avoiding the risk of the photoelectric glass falling and ensuring the safety of personnel and equipment.

[0019] Secondly, by adjusting the double-headed electric threaded rod in the unit, the two sliders can be driven to slide relative to each other in the slide rail, thereby adjusting the distance between the two suction cups, so as to be able to adapt to large-size optoelectronic glass of different lengths and widths.

[0020] Third, by setting up a buffer unit consisting of a hydraulic rod and a spring, when the suction cup contacts the photoelectric glass, the extension and contraction of the hydraulic rod combined with the elastic deformation of the spring can effectively offset the rigid pressure, thereby avoiding damage or breakage of the glass surface due to the impact force during the adsorption process.

[0027] like Figures 1 to 5 As shown, a vacuum adsorption and transfer device for large-size optoelectronic glass includes a crossbeam frame 1. Support frames 2 are welded and installed on the lower surfaces of both ends of the crossbeam frame 1. An electric push rod 4 is fixedly installed on the upper surface of the support frame 2. The working end of the electric push rod 4 passes through the crossbeam frame 1 and is fixedly installed with a slide rail 61. A guide rod 5 is fixedly installed in a groove opened on the inner surface of the support frame 2. The two ends of the slide rail 61 are slidably connected to the outer surfaces of the two guide rods 5 respectively. Two sliders 63 are slidably installed on the inner surface of the slide rail 61. A connecting plate 64 is fixedly installed on the lower surface of the two sliders 63. A buffer unit 7 is provided on the lower surface of the two connecting plates 64 to buffer the optoelectronic glass during adsorption.

[0028] The crossbeam frame 1 and the two support frames 2 form the complete skeleton of the assembled device. The electric push rod 4 is powered by the device's own power supply, which can push the slide rail 61 to move up and down. The two ends of the slide rail 61 are respectively slidably mounted on the two guide rods 5, which plays a stabilizing role in the up and down sliding of the slide rail 61. Both sliders 63 can slide in the slide rail 61, and the connecting plate 64 slides along with the sliders 63.

[0029] The buffer unit 7 includes hydraulic rods 71, and four hydraulic rods 71 ​​are provided. The four hydraulic rods 71 ​​are located at the four corners of the lower surface of the two connecting plates 64. The other end of the four hydraulic rods 71 ​​is provided with a suction cup 74. The outer surface of the suction cup 74 is provided with a lifting unit 8 for preventing falling and protecting the photoelectric glass during adsorption and transportation.

[0030] The hydraulic rod 71 is designed to counteract the directional force generated by the spring 73 after buffering.

[0031] The lifting unit 8 includes electric push rod 2 87 and support plate 88. There are three electric push rods 2 87. The working ends of the three electric push rods 2 87 are fixedly installed with a support plate 88. The three support plates 88 drive one electric push rod 2 87 to support the photoelectric glass.

[0032] The electric push rod 87 operates through the device's built-in power supply, enabling it to move the support plate 88 up and down, thereby contacting and detaching from the photoelectric glass.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, a double-headed electric threaded rod 81 is fixedly installed on the upper surface of the suction cup 74. Both working ends of the double-headed electric threaded rod 81 are threaded with slide rods 84. Two limiting rings 82 are symmetrically welded to the upper surface of the suction cup 74. The two slide rods 84 are slidably connected in the limiting rings 82.

[0034] The double-headed electric threaded rod 81 operates through the device's built-in power supply. The operation of the double-headed electric threaded rod 81 cooperates with the limiting ring 82, which enables the slide rod 84 to slide within the limiting ring 82. Through the sliding of the slide rod 84, the support plate 88 can be positioned below the suction cup 74 or detached from the suction cup 74.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, limit rings 2 83 are welded and installed at the four corners of the upper surface of suction cup 74. A slide rod 2 85 is slidably installed in one limit ring 2 83. A crossbar 86 is welded and installed at the other end of the two slide rods 2 85 and the slide rod 1 84.

[0036] Two slide rods 85 and one slide rod 84 form a moving rod, and the two slide rods 85 are slidably connected in two limiting rings 83, thereby ensuring the stability of the moving rod formed by the two slide rods 85 and one slide rod 84.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, three electric push rods 87 are respectively installed in the grooves opened on the outer surface of one slide rod 84 and two slide rods 85.

[0038] The three electric actuators 287 operate via the device's built-in power supply.

[0039] like Figure 3 As shown, a partition plate 72 is welded and installed on the outer surface of the hydraulic rod 71, and a spring 73 is sleeved on the working end of the hydraulic rod 71.

[0040] One end of the spring 73 contacts the lower surface of the connecting plate 64, and the other end contacts the upper surface of the partition 72.

[0041] like Figure 2 and Figure 3As shown, the adjustment unit 6 includes a double-headed electric threaded rod 62, which is fixedly installed on the inner surface of the slide rail 61, and two sliders 63 are respectively installed on the two working ends of the double-headed electric threaded rod 62.

[0042] The double-headed electric threaded rod 62 can drive two sliders 63 to slide in the slide rail 61. One slider 63 is connected by a forward thread, and the other slider 63 is connected by a reverse thread.

[0043] like Figure 1 As shown, two casters 3 are installed on the lower surface of each of the two support frames 2.

[0044] The casters 3 enable the crossbeam frame 1 and the two support frames 2, which together form the complete skeleton of the device, to move.

[0045] Working principle:

[0046] The frame formed by the crossbeam frame 1 and the support frame 2 is moved by four universal wheels 3, so that the photoelectric glass is positioned between the two support frames 2.

[0047] By activating the double-headed electric threaded rod 62, the two sliders 63 slide relative to each other in the slide rail 61, thereby causing the two sliders 63 to move the two suction cups 74 to a length that matches the photoelectric glass. Then, the electric push rod 4 is activated to move the slide rail 61 downward, thereby moving the suction cups 74 downward.

[0048] As the suction cup 74 moves downward, the suction nozzle of the suction cup 74 contacts the upper surface of the photoelectric glass. In order to ensure that the suction nozzle of the suction cup 74 is in close contact with the upper surface of the photoelectric glass, the suction cup 74 continues to move downward. The hydraulic rod 71 and the spring 73 work together to cushion the suction cup 74 from pressing the photoelectric glass, preventing the photoelectric glass from breaking. After the adsorption is completed, the electric push rod 4 is activated to lift the photoelectric glass to 50 centimeters above the ground.

[0049] The double-headed electric threaded rod 81 is activated to drive the two moving rods, consisting of slide rod 84, two slide rods 85, and cross rod 86, to slide inward. Then, the three electric push rods 87 are activated to drive the support plate 88, which has a rubber pad on its surface, to stick tightly to the lower surface of the photoelectric glass. Then, the electric push rod 4 is activated to lift and transport the photoelectric glass, thereby ensuring that the suction cup 74 is not firmly attached, so as to prevent the photoelectric glass from falling and being damaged or causing injury to people.

[0050] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
