Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a gripper device. Background Technology

[0002] During television screen production, gripper mechanisms are typically used for gripping and transferring screens to facilitate production flow. However, television screens vary in size; for example, an 85-120 inch ultra-large television has a length * width of 2700mm * 1554mm, making it very large and weighing up to 150KG, which is difficult to handle manually. Existing technology uses gripper mechanisms for gripping and transferring screens, with wedges at the contact points between the grippers and the screen to grip the screen without making contact with the screen surface. However, this mechanism has the following drawbacks: 1. Television screen sizes vary, and gripper mechanisms are difficult to adjust flexibly to accommodate different screen sizes; 2. The contact points between the wedges and the screen are prone to wear over long-term use, reducing their lifespan and posing a risk of scratching the screen casing. Since the wedges and grippers are usually fixed with bolts, they need to be disassembled and replaced manually, a complex process. Therefore, designing a gripper device that can handle screens of different sizes and allows for quick wedge replacement is a problem that needs to be solved by those in the field. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a gripper device that can handle and transfer screens of different sizes and allows for quick replacement of the inclined blocks.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a gripper device, comprising:

[0005] A connecting plate, on which a drive assembly is mounted;

[0006] Multiple gripper assemblies are arranged opposite to each other at the moving end of the drive assembly, and the drive assembly is capable of driving the gripper assemblies to move along the X-axis and Y-axis directions of the connecting plate.

[0007] The gripper assembly includes a wedge block disposed at the gripping end of the gripper assembly, the wedge block having a beveled edge, and the gripper assembly being able to grip the side of the screen via the beveled edge;

[0008] A limiting component is disposed on the gripper assembly, the limiting component being able to be inserted into and positioned within the inclined block.

[0009] Furthermore, the gripper assembly includes a frame disposed at the moving end of the drive assembly, the inclined block is T-shaped and is detachably inserted into the frame, the side of the inclined block inserted into the frame has a through hole, and the moving end of the limiting assembly is inserted into the through hole.

[0010] Furthermore, the frame has an adjustment cavity aligned with the through hole inside. The limiting component includes a pin that is slidably disposed in the adjustment cavity. A spring is disposed inside the adjustment cavity. The spring can push the pin so that one end is inserted into the through hole, and the end of the pin away from the through hole extends out of the frame.

[0011] Furthermore, the connecting plate has a mounting hole at its center, and a limiting component is provided at the mounting hole. The limiting component can hold the screen in place after each gripper assembly clamps the screen.

[0012] Furthermore, the limiting component includes an electric push rod disposed at the corresponding mounting hole of the connecting plate, and the moving end of the electric push rod is provided with a flexible pressure plate.

[0013] Furthermore, the drive assembly includes an X-axis adjustment module and a Y-axis adjustment module. The X-axis adjustment module is mounted on the connecting plate, and the Y-axis adjustment module is mounted on the moving end of the X-axis adjustment module. The Y-axis adjustment module has no fewer than four moving ends, and each frame is respectively mounted on the corresponding moving end of the Y-axis adjustment module.

[0014] The beneficial effects of this utility model are reflected in:

[0015] In this invention, the driving component drives each gripper assembly to move along the X and Y axes of the connecting plate, thus adapting to and clamping screens of various sizes. The gripper assembly is then moved to hold the screen. The inclined block design ensures that the gripper assembly contacts the screen's sidewall only through the inclined edge of the block, preventing direct contact and damage. Furthermore, the limiting component allows for quick insertion and positioning within the inclined block, replacing bolts and enabling rapid limiting or release of the inclined block. This makes replacement and maintenance of the inclined block convenient, facilitating practical use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model discloses a gripper device, including a connecting plate 1 and multiple gripper assemblies 4. A driving assembly is provided on the connecting plate 1, and the multiple gripper assemblies 4 are arranged opposite to each other at the moving end of the driving assembly. The driving assembly can drive each gripper assembly 4 to move along the X-axis and Y-axis directions of the connecting plate 1. Multiple weight-reducing holes are provided on the connecting plate 1, which are used to reduce the overall weight of the device.

[0025] In one embodiment, the gripper assembly 4 includes a wedge 42 disposed at the gripping end of the gripper assembly 4. The wedge 42 has a bevel, and the gripper assembly 4 can grip the side of the screen through the bevel on the wedge 42. A limiting component 7 is disposed on the gripper assembly 4, and the limiting component 7 can be inserted into the wedge 42 and positioned thereon.

[0026] In practice, the driving component drives each gripper assembly 4 to move along the X and Y axes of the connecting plate 1. It is compatible with screens with a length of 1800mm-3000mm and a width of 1000mm-1650mm, thus adapting to and clamping screens of various sizes. Then, the gripper assembly 4 is moved to clamp the screen. With the setting of the inclined block 42, the gripper assembly 4 can contact the side wall of the screen only through the inclined edge of the inclined block 42 when clamping the screen. This method can prevent the gripper assembly 4 from directly contacting the screen surface and causing damage. In addition, by setting the limiting component 7, it can be quickly inserted into the inclined block 42 and positioned. This method replaces the bolt fixing method and can quickly limit or release the inclined block 42, making it very convenient to replace and maintain the inclined block 42, thus facilitating practical use.

[0027] In one embodiment, the gripper assembly 4 includes a frame 41 mounted on the moving end of the drive assembly, and a T-shaped wedge 42 detachably inserted into the frame 41. The side of the wedge 42 inserted into the frame 41 has a through hole 43, and the moving end of the limiting assembly 7 is inserted into the through hole 43.

[0028] This design, by controlling the limiting component 7 to insert its moving end into or out of the through hole 43, can effectively limit or release the limiting of the inclined block 42 inserted into the frame 41. This method replaces the bolt fixing method, which can quickly remove and replace the worn inclined block 42, and can make the new inclined block 42 have good installation stability after being limited.

[0029] In one embodiment, the frame 41 has an adjustment cavity aligned with the through hole 43 inside. The limiting component 7 includes a pin 71 slidably installed in the adjustment cavity. A spring 72 is installed inside the adjustment cavity. The spring 72 can push the pin 71 so that one end is inserted into the through hole 43. The end of the pin 71 away from the through hole 43 extends out of the frame 41.

[0030] In practice, the staff touches the end of the pin 71 located outside the frame 41, and then pushes and pulls the pin 71 to insert it into the through hole 43 or to remove it from the through hole 43, so that the inclined block 42 can be limited or released from the limit. The spring 72 can make the pin 71 very stable when it is inserted into the through hole 43, and it will not easily come out.

[0031] In one embodiment, the connecting plate 1 includes a plate body 11, and a mounting hole 12 is formed at the center of the plate body 11, where a limiting component is provided.

[0032] With this design, the limiting component can hold the screen in place after each gripper assembly 4 clamps the screen, so that screens of different sizes can be simultaneously limited by the gripper assembly 4 and the limiting component. This method can improve the stability of the screen after it is clamped and will not affect its clamping stability due to insufficient contact area between the screen and the gripper assembly 4.

[0033] In one embodiment, the limiting component includes an electric push rod 5 installed at the corresponding mounting hole 12 of the connecting plate 1, and a soft pressure plate 6 is installed at the moving end of the electric push rod 5, which may be a sheet of rubber.

[0034] In practice, when the screen is clamped, the back of the screen faces the electric push rod 5. The electric push rod 5 is then operated, and its moving end drives the pressure plate 6 to move towards the back of the screen until the pressure plate 6 contacts the back of the screen. Together with the gripper assemblies 4, the screen can be positioned more stably after being clamped, which is beneficial for the stable transfer of the screen. Since the shape of the back of the screen varies depending on its specific design, the use of a flexible pressure plate 6 can adapt to different shapes of screen backs.

[0035] In one embodiment, the drive assembly includes an X-axis adjustment module 2 and a Y-axis adjustment module 3. The X-axis adjustment module 2 is mounted on the connecting plate 1, and the Y-axis adjustment module 3 is mounted on the moving end of the X-axis adjustment module 2. The Y-axis adjustment module 3 has no less than four moving ends, and each frame 41 is mounted on the corresponding moving end of the Y-axis adjustment module 3.

[0036] The X-axis adjustment module 2 and Y-axis adjustment module 3 mentioned above are both linear modules. Linear modules are common knowledge in this field, so their specific structural composition and working principle will not be described in detail here.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
