Description

Technical Field

[0001] This utility model belongs to the field of glass testing technology, and in particular relates to a material handling device and an automotive windshield testing equipment. Background Technology

[0002] Head-up displays (HUDs) used in automobiles utilize the principle of optical reflection to project important vehicle information onto the windshield via a projector. The projector is positioned at roughly eye level with the driver, allowing them to view information without looking down. This places higher demands on the quality of automotive windshields, making windshield quality inspection particularly important. Currently, inspecting automotive windshields requires mounting them on specialized testing equipment.

[0003] During the testing process, glass often needs to be transferred between different workstations, such as from storage racks to glass testing equipment for performance testing. This transfer typically involves a handling device. Specifically, the handling device moves above the storage rack, attaches to the upper surface of the glass, lifts the glass until it is detached from the rack's support, and then performs horizontal transport, ultimately placing the glass precisely in the designated position on the glass testing equipment. However, during the lifting and transport of glass, the adhesion force can fluctuate or become insufficient due to glass surface issues, excessive load, or sudden vibrations. This can cause the glass to detach during lifting or transport, resulting in glass breakage, equipment damage, or even safety accidents. Utility Model Content

The lifting plate can be driven by an external force and rises and falls relative to the support frame. The material is located below the lifting plate and spaced apart from the lifting plate. One end of the elastic connector is connected to the lifting plate, and the other end of the elastic connector is detachably connected to the material. The elastic connector is in a stretched state so that the elastic connector applies an upward pulling force to the material under the action of elastic restoring force.

[0007] In some embodiments, a plurality of elastic connectors are arranged, and each elastic connector is arranged at circumferential intervals along the lifting plate.

[0008] In some embodiments, the elastic connector includes an elastic element having an elastic restoring force and connected to the lifting plate, and a hook connected to one end of the elastic element away from the lifting plate. The hook is used to hook the material so that the hook lifts the material under the action of the elastic restoring force of the elastic element.

[0009] In some embodiments, the material handling device further includes a mounting base disposed on the lifting plate and a first pin connected to the mounting base, the hook includes a main body and a second pin connected to the main body, and the two ends of the elastic member are respectively hooked to the first pin and the second pin.

[0010] In some embodiments, the material handling device further includes a telescopic member connected to the support frame, the lifting plate being connected to the bottom end of the telescopic member, and the telescopic member being telescopically extended and retracted in a preset direction to drive the lifting plate to rise and fall in the preset direction.

[0011] In some embodiments, the telescopic member is a spring balancer, which is used to balance the weight of the lifting plate and the material.

[0012] In some embodiments, the adsorption structure includes suction cups for adsorbing the material, with multiple suction cups arranged at intervals.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1 to 3 This application provides a material handling device, which includes a support frame 10, a lifting plate 20 slidably disposed on the support frame 10, an adsorption structure 30 connected to the lifting plate 20 and used for adsorbing materials, and an elastic connector 40 with elastic restoring force. The lifting plate 20 can be driven by an external force and rise and fall relative to the support frame 10. The material is located below the lifting plate 20 and spaced apart from the lifting plate 20. One end of the elastic connector 40 is connected to the lifting plate 20, and the other end of the elastic connector 40 is detachably connected to the material. The elastic connector 40 is in a stretched state so that the elastic connector 40 applies an upward pulling force to the material under the action of elastic restoring force.

[0028] It should be noted that the material in this embodiment can be glass, specifically an automotive windshield. Therefore, the material handling device in this embodiment is used to pick up the glass at a preset workstation. In specific operation, the material handling device needs to move above the storage rack for storing the glass. The lifting plate 20 descends so that the adsorption structure 30 can adsorb the upper surface of the glass. Then, the lifting plate 20 rises to lift the glass until it is freed from the support of the storage rack. Subsequent horizontal transfer is then performed, ultimately placing the glass precisely at the designated position on the glass testing equipment, thereby enabling glass testing.

[0029] Understandably, the adsorption force of the adsorption structure 30 on the material is adjustable. When the material needs to be released to a designated position of the glass testing equipment, the lifting plate 20 descends to a predetermined height above the designated position, and then the adsorption force of the adsorption structure 30 on the material is released, so that the material detaches from the adsorption structure 30 and falls to the designated position.

[0030] In this embodiment, the lifting plate 20 is driven by an external force to rise and fall relative to the support frame 10, thereby enabling the adsorption structure 30 connected to the lifting plate 20 and the material adsorbed by the adsorption structure 30 to rise and fall synchronously relative to the support frame 10. Optionally, the lifting plate 20 can be manually pulled up and down by an operator, or a drive device can be set to automatically drive the lifting plate 20 to rise and fall. This embodiment does not limit the lifting drive method of the lifting plate 20 to a single method.

[0031] In this embodiment, when the elastic connector 40 is not connected to the material, it hangs naturally under the influence of gravity. When the material is adsorbed onto the adsorption structure 30, the free end of the elastic connector 40 is connected to the material. The elastic connector 40 is located below the lifting plate 20 and is connected between the material and the lifting plate 20. Since the material and the lifting plate 20 are spaced apart, when the distance between the material and the lifting plate 20 is large enough, the elastic connector 40 connected between the material and the lifting plate 20 is in a stretched state. Thus, under the action of the elastic restoring force of the elastic connector 40, the elastic connector 40 can apply a continuous upward pulling force to the material.

[0032] The material handling device provided in this application, after the adsorption structure 30 adsorbs the material, the elastic connector 40 connected between the lifting plate 20 and the material is in a stretched state. Under the action of the elastic restoring force of the elastic connector 40, the elastic connector 40 applies a continuous upward auxiliary pulling force to the material. This auxiliary pulling force effectively shares the glass weight that the adsorption structure 30 needs to overcome, thereby reducing the load on the adsorption structure 30, avoiding adsorption failure, reducing the risk of material falling off, and thus improving the safety of material handling.

[0033] In some embodiments, multiple elastic connectors 40 are arranged, with each elastic connector 40 spaced apart circumferentially along the lifting plate 20. The multiple elastic connectors 40 spaced apart circumferentially ensure a uniform distribution of the auxiliary lifting force applied to the edge of the material, preventing tilting, twisting, or stress concentration of the material due to uneven force at a single point or in a localized area. Furthermore, during horizontal transfer, multi-point constraints create torque balance, effectively suppressing the swaying or shaking of the material due to inertia, and reducing the probability of the material detaching from the adsorption structure 30 during transfer.

[0034] Furthermore, if contamination at the edge of the material reduces the constraint force of a single elastic connector 40 on the material, the remaining elastic connectors 40 can still provide sufficient auxiliary lifting force and constraint, significantly reducing the risk of the material falling as a whole and improving the system's fault tolerance. Optionally, in this embodiment, the lifting plate 20 is a quadrilateral plate structure, and each elastic connector 40 can be connected to each corner of the lifting plate 20.

[0035] In some embodiments, the elastic connector 40 includes an elastic element 41 with elastic restoring force connected to the lifting plate 20, and a hook 42 connected to the end of the elastic element 41 facing away from the lifting plate 20. The hook 42 is used to hook material so that the hook 42 lifts the material under the action of the elastic restoring force of the elastic element 41. By setting the hook 42 to hook material, specifically, the hook 42 is used to hook the edge of the material, which is simple to operate and facilitates the operator to quickly connect the elastic connector 40 to the material, thereby improving the material picking efficiency. Furthermore, when the hook 42 hooks the edge of the material, the weight of the material itself will force the contact point between the hook 42 and the edge of the material to press downward, forming a mechanical self-locking similar to a "barb". When the picking device stops suddenly, turns, or is subjected to external impact, the self-locking effect can prevent the material from slipping out of the hook 42, thereby further improving the safety of material picking. Optionally, the elastic element 41 is a spring, specifically a compression spring, a tension spring, or a torsion spring, etc.

[0036] In some embodiments, the material handling device further includes a mounting base 52 disposed on the lifting plate 20 and a first pin 51 connected to the mounting base 52. The hook 42 includes a main body 421 and a second pin 422 connected to the main body 421. The two ends of the elastic member 41 are hooked to the first pin 51 and the second pin 422 respectively. Specifically, hooks can be provided at both ends of the elastic member 41. By setting the two ends of the elastic member 41 to hook to the first pin 51 and the second pin 422 respectively, the two ends of the elastic member 41 form a hinged connection through the pins, allowing the elastic member 41 to swing slightly radially during operation, automatically compensating for small positional deviations at the edge of the material. Furthermore, the elastic member 41 is directly hooked onto the second pin 422 of the first pin 51 through the hooks at both ends, without the need for bolts or clamps, allowing for quick disassembly and replacement. Moreover, the hook 42 and the elastic member 41 are independent modules, and any damaged component can be replaced individually.

[0037] In some embodiments, the material handling device further includes a telescopic member 60 connected to the support frame 10, and a lifting plate 20 connected to the bottom end of the telescopic member 60. The telescopic member 60 is telescopically extended along a preset direction a to drive the lifting plate 20 to rise and fall along the preset direction a. By setting the telescopic member 60, since the top end of the telescopic member 60 is fixedly connected to the support frame 10 and the lifting plate 20 is connected to the bottom end of the telescopic member 60, when the telescopic member 60 extends along the preset direction a, the lifting plate 20 descends along the preset direction a, and when the telescopic member 60 retracts along the preset direction a, the lifting plate 20 rises along the preset direction a. The structure is simple and easy to operate, thereby effectively improving the material handling efficiency.

[0038] Optionally, the telescopic component 60 is a spring balancer, used to balance the weight of the lifting plate 20 and the material. The spring balancer typically consists of a drum and a steel wire rope wound around it. The steel wire rope connects to the lifting plate 20, and the drum is also connected to a coil spring. The torque of the coil spring is used to balance the weight of the suspended object. Once the load is suspended by the spring balancer, by setting the preload of the coil spring, the spring generates a torque attempting to rewind the steel wire rope, which balances the gravitational torque generated by the load attempting to pull the steel wire rope out. At this point, the load appears to be in a "weightless" state, and the operator only needs to apply a small force to move it. This allows the operator to easily raise and lower the load, or suspend the load at any height, thereby greatly reducing the operator's physical burden and fatigue, and improving work efficiency and operational comfort.

[0039] Optionally, two telescopic components 60 are arranged at intervals, with each of the two telescopic components 60 corresponding to one end of the lifting plate 20, thereby improving the balance of the lifting plate 20 during the lifting process. In addition, two handles 73 are connected to the top edge of the lifting plate 20, with two handles 73 arranged at intervals, so that operators on both sides can hold the handles 73 and pull the lifting plate 20 up and down, thereby improving the convenience of operation.

[0040] In some embodiments, the adsorption structure 30 includes suction cups 31 for adsorbing materials, with multiple suction cups 31 arranged at intervals. The picking device also includes a vacuum generator 71 connected to the support frame 10, and each suction cup 31 is connected to the vacuum generator 71. By setting the vacuum generator 71, a negative pressure environment is formed between the suction cups 31 and the material, thereby stabilizing the adsorption of materials and realizing a low-stress contact picking method. This largely avoids the indentations, scratches, or deformations that may be caused by traditional grippers on the material surface, significantly reducing damage to the material surface. Furthermore, the use of multiple suction cups 31 for adsorption, with each suction cup 31 corresponding to multiple adsorption positions of the material, makes the state of the adsorbed material more stable.

[0041] Optionally, the vacuum generator 71 is a miniature DC vacuum pump. Miniature DC vacuum pumps are typically designed to be more compact, easy to carry and install, and particularly suitable for space-constrained environments. Their lightweight design makes moving and deploying the material handling device easier, increasing operational flexibility. Furthermore, miniature DC vacuum pumps usually incorporate noise and vibration control, making them quieter and smoother during operation. This contributes to a more comfortable working environment and reduces disturbance to workers and the surrounding environment. In addition, miniature DC vacuum pumps have low energy consumption, are energy-efficient and environmentally friendly, helping to conserve energy and reduce environmental impact.

[0042] Furthermore, because the auxiliary pulling force of the elastic connector 40 stably shares part of the weight of the material, the adsorption force required to be maintained by the adsorption mechanism is significantly reduced. This not only reduces the power requirements and energy consumption of power sources such as vacuum pumps, but also reduces the stress on the suction cup 31 itself and its seals, thereby extending the service life of the adsorption structure 30 and reducing maintenance costs and failure rates.

[0043] Optionally, a control box 72 is provided on each side of the lifting plate 20. The control box 72 is used to control the start and stop of the vacuum generator 71. Each control box 72 is equipped with two buttons, so the two control boxes 72 have a total of four buttons. All four buttons need to be pressed at the same time to control the start and stop of the vacuum generator 71, thereby reducing the risk of misoperation.

[0044] In some embodiments, each elastic connector 40 is disposed on the edge of the lifting plate 20, and the number of elastic connectors 40 is equal to the number of suction cups 31. Each suction cup 31 corresponds one-to-one with each elastic connector 40, and each suction cup 31 is adjacent to each elastic connector 40. Thus, each suction cup 31 has a corresponding elastic connector 40 working in cooperation. When the suction force of a suction cup 31 fails due to factors such as material surface contamination, the adjacent elastic connector 40 can immediately bear the load of that area, thereby further improving safety. Specifically, there are four elastic connectors 40, which are respectively connected to the four corners of the lifting plate 20, and four suction cups 31 are also provided accordingly.

[0045] In some embodiments, the support frame 10 includes a base 11, a cantilever 12 connected to the base 11 and extending horizontally, and a connecting plate 13 connected to the cantilever 12. A lifting plate 20 is slidably connected to the connecting plate 13, and multiple casters 80 are connected to the bottom of the base 11. The horizontally extending cantilever 12 facilitates extending the lifting plate 20 above the storage rack for easy material retrieval. Furthermore, the multiple casters 80 connected to the bottom of the base 11 allow operators to easily push the base 11 and drive the material retrieval device to move between workstations. Additionally, an electrical control box 14 is installed on the base 11, containing a battery.

[0046] In the actual material handling process, the material handling device is first pushed to the front of the storage rack, so that the lifting plate 20 is directly above the material. Then, the operators on both sides pull the handles 73 to lower the lifting plate 20. When the suction cup 31 fully contacts the material, the button on the control box 72 is pressed simultaneously, the vacuum generator 71 is activated, the suction cup 31 picks up the material, and then the hook 42 hooks the material. Next, the operator raises the lifting plate 20 to the top, and the lifting plate 20 is suspended at the top position. Finally, the operator pulls out the material handling device and transfers it to the glass testing equipment. In the material unloading process, the cantilever 12 is extended into the glass testing equipment, so that the material is directly above the glass clamp in the testing equipment. Then, the hook 42 is removed, the operator presses down the lifting plate 20 and puts the material into the glass clamp. After confirming that the material is in place, the button on the control box 72 is pressed to release the material. Finally, the operator raises the lifting plate 20 to the highest position again and pulls the material handling device out of the glass testing equipment.

[0047] This utility model also proposes an automotive windshield inspection device, which includes a material taking device. The specific structure of the material taking device is as described in the above embodiments. Since this automotive windshield inspection device adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0048] In summary, the material handling device provided in this application, after the adsorption structure 30 adsorbs the material, the elastic connector 40 connected between the lifting plate 20 and the material is in a stretched state. Under the action of the elastic restoring force of the elastic connector 40, the elastic connector 40 applies a continuous upward auxiliary pulling force to the material. This auxiliary pulling force effectively shares the weight of the glass that the adsorption structure 30 needs to overcome, thereby reducing the load on the adsorption structure 30, avoiding adsorption failure, reducing the risk of material falling off, and thus improving the safety of material handling.
