Abstract
Description
Technical Field
[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a worktable and laser processing equipment. Background Technology
[0002] In the production process of OLED panels, the carrier plate typically needs to be moved back and forth between different workstations to complete various complex processing steps. To achieve precise movement of the carrier plate, the worktable is usually equipped with a movable carrier plate and guides are installed on the worktable to guide the carrier plate to move smoothly and accurately along a predetermined path, thereby ensuring the positional accuracy and processing quality of the OLED panel during processing.
[0003] However, laser processing is a common process in OLED panel production. The laser processing generates high temperatures, which can cause deformation of the guide components, leading to deviations in their original guiding function. Once the guide components deform, the carrier board cannot move along the correct path during transport, severely impacting production efficiency and failing to meet production cycle requirements. Utility Model Content
[0004] This application provides a worktable and laser processing equipment that can prevent the guide from deforming and causing the carrier plate to become immobile, thus meeting the requirements of production cycle time.
[0005] The technical solution adopted in this application embodiment is: providing a workbench, including:
[0006] Workbench body;
[0007] Guide components are installed on the worktable body;
[0008] A support assembly includes a carrier plate and a flexible connector. The carrier plate is connected to the guide member via the flexible connector. The carrier plate is used to support the workpiece, and the flexible connector is used to compensate for the positional deviation of the guide member.
[0009] A driving element, connected to the carrier plate, drives the carrier plate to move along the length direction of the guide element.
[0010] Optionally, the flexible connector is provided with a first groove and a second groove, the length directions of the first groove and the second groove are parallel to the length direction of the guide, and the first groove and the second groove are respectively provided on both sides of the flexible connector.
[0011] Optionally, the positions of the first and second cuts are staggered.
[0012] Optionally, the flexible connector is provided with a third groove, the length direction of which is perpendicular to the length direction of the guide.
[0013] Optionally, there are at least two third grooves, which are spaced apart along the length of the flexible connector.
[0014] Optionally, the third groove is disposed on the side of the flexible connector near the guide.
[0015] Optionally, the support assembly further includes a connecting plate disposed on the side of the flexible connector away from the carrier plate. The connecting plate is connected to the guide member, and the driving member is throttledly connected to the connecting plate to drive the carrier plate to move along the length direction of the guide member.
[0016] Optionally, the carrier plate is provided with a plurality of height-adjustable supports, which are used to support the workpiece to adjust the levelness of the workpiece's machined surface.
[0017] Optionally, the worktable further includes a position detection component connected to the carrier plate to detect the displacement of the carrier plate.
[0018] This application also provides a laser processing device, including the aforementioned worktable.
[0019] The beneficial effects of the worktable and laser processing equipment provided in this application embodiment are as follows: The worktable in this application embodiment connects the carrier plate and the guide plate by setting a flexible connector. When the guide plate deforms due to the high temperature of laser processing, the flexible connector can compensate for the positional deviation of the guide plate. This compensation mechanism enables the carrier plate to maintain a relatively accurate path during movement, avoids the positional deviation of the carrier plate caused by the deformation of the guide plate, ensures that the OLED panel is always in the correct position during processing, and improves the processing quality of the product.
[0020] The introduction of flexible connectors allows the worktable to better adapt to the high-temperature environment generated during laser processing. Even if the guide components deform to a certain extent, the worktable can still operate normally without frequent downtime for maintenance or replacement of the guide components. This greatly enhances the worktable's adaptability to complex processing environments, improves the stability and reliability of the equipment, and reduces equipment maintenance costs and downtime.
[0021] The laser processing equipment of this application embodiment includes the aforementioned worktable, and therefore has the beneficial effects brought about by the aforementioned worktable, which will not be repeated here. Attached Figure Description

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0036] Please see Figure 1 and Figure 2 The worktable provided in this application embodiment will now be described. The worktable provided in this application embodiment includes a worktable body 1, a guide member 2, a support assembly 3, and a drive member 4. The guide member 2 is mounted on the worktable body 1. The support assembly 3 includes a carrier plate 31 and a flexible connector 32. The carrier plate 31 is connected to the guide member 2 via the flexible connector 32. The carrier plate 31 supports the workpiece, and the flexible connector 32 compensates for positional deviations of the guide member 2. The drive member 4 is connected to the carrier plate 31 to drive the carrier plate 31 to move along the length direction of the guide member 2.
[0037] In this embodiment, the workbench body 1 is used to support and mount other components. The workbench body 1 may be made of high-strength metal materials, such as high-quality steel, to ensure sufficient rigidity and stability. The shape of the workbench body 1 may be designed as rectangular or other suitable shapes according to actual production needs, and its dimensions should meet the requirements of the moving range of the carrier plate 31.
[0038] Preferably, the workbench body 1 may include two horizontal bars and two vertical bars. The two horizontal bars are parallel and opposite to each other, and the two vertical bars are parallel and opposite to each other. The two horizontal bars are connected to the two vertical bars respectively to form a base for supporting other components. This structure can reduce material consumption, shorten processing time, and lower production costs.
[0039] Both horizontal and vertical stripes can be made of marble blocks. Marble is a metamorphic rock formed from pre-existing rock in the Earth's crust over millions of years under high temperature and pressure. Marble possesses excellent properties such as high grinding precision, low coefficient of thermal expansion, no stress release, and dimensional stability. A marble worktable body 1 can effectively ensure the high precision of the laser equipment's workpiece stage, thereby ensuring the precision and stability of product processing.
[0040] Guide members 2 are mounted on the worktable body 1 to guide the carrier plate 31 along a predetermined path. Guide members 2 can be in the form of linear guide rails. Guide members 2 are fixed to the worktable body 1 with screws or other fasteners to ensure a secure installation and prevent loosening due to the movement of the carrier plate 31. Two guide members 2 can be provided, positioned opposite each other on the worktable body 1, with both guide members 2 simultaneously guiding the carrier plate 31, thus improving the stability of the carrier plate 31's movement.
[0041] The support assembly 3 includes a carrier plate 31 and a flexible connector 32. The carrier plate 31 is used to support workpieces such as OLED panels, and its shape and size are designed according to the size and shape of the workpiece to ensure that the workpiece can be stably placed on the carrier plate 31. The carrier plate 31 can be made of lightweight, high-strength aluminum alloy or carbon fiber composite material to reduce the weight of the carrier plate 31 and reduce the energy consumption of the drive component 4.
[0042] The flexible connector 32 is used to connect the carrier plate 31 and the guide member 2 to compensate for positional deviations of the guide member 2. The flexible connector 32 can be made of flexible metal sheets, elastic rubber strips, or other materials with elasticity and flexibility. In this embodiment, the flexible connector 32 can be a structure composed of multiple layers of flexible metal sheets, with each layer fixed by welding or riveting to form a connector with a certain strength and elasticity. One end of the flexible connector 32 is connected to the carrier plate 31 by screws or clips, and the other end is connected to the guide member 2. The connection method can be a threaded connection, a slot connection, etc., to ensure a firm and reliable connection.
[0043] The drive unit 4 can be driven by a motor, such as a stepper motor or a servo motor. The motor control signal is provided by an external control system, which can precisely control the moving speed and position of the carrier plate 31 according to actual production needs. There can be two drive units 4, which are arranged opposite each other on the worktable body 1 and connected to both sides of the carrier plate 31 respectively, so as to jointly drive the carrier plate 31 and improve the load capacity.
[0044] In this embodiment, the worktable connects the carrier plate 31 and the guide member 2 via a flexible connector 32. When the guide member 2 deforms due to the high temperature of laser processing, the flexible connector 32 can compensate for the positional deviation of the guide member 2. This compensation mechanism ensures that the carrier plate 31 maintains a relatively accurate path during movement, avoiding positional displacement of the carrier plate 31 caused by the deformation of the guide member 2. This ensures that the workpiece (e.g., an OLED panel) remains in the correct position during processing, improving the processing quality of the product.
[0045] The introduction of the flexible connector 32 allows the worktable to better adapt to the high-temperature environment generated during laser processing. Even if the guide 2 deforms to a certain extent, the worktable can still operate normally without frequent downtime for maintenance or replacement of the guide 2. This greatly enhances the worktable's adaptability to complex processing environments, improves the stability and reliability of the equipment, and reduces equipment maintenance costs and downtime.
[0046] For preferred options, please refer to [link / reference]. Figure 3 The flexible connector 32 is provided with a first groove 321 and a second groove 322. The length direction of the first groove 321 and the second groove 322 is parallel to the length direction of the guide member 2. The first groove 321 and the second groove 322 are respectively provided on both sides of the flexible connector 32.
[0047] The flexible connector 32 can be made of metal, and its shape can be strip-shaped. The first groove 321 and the second groove 322 are formed on the flexible connector 32 to reduce its rigidity and increase its flexibility. Compared with directly using a flexible material as the flexible connector 32, the positional offset of the carrier plate 31 after movement is smaller, the accuracy is higher, and the response to the driving component 4 is faster.
[0048] The length directions of the first cut groove 321 and the second cut groove 322 are parallel to the length direction of the guide member 2. In this way, the flexible connector 32 can adapt to the deformation of the guide member 2 in the length direction, so as to compensate for the positional deviation of the guide member 2 in the length direction.
[0049] The first cutting groove 321 and the second cutting groove 322 are staggered.
[0050] The first cut 321 and the second cut 322 are staggered, meaning that the first cut 321 and the second cut 322 are not completely aligned along the length of the flexible connector 32. This staggered cut design can further improve the deformation capacity and compensation effect of the flexible connector 32. At the same time, it can prevent the flexible connector 32 from being easily broken due to the cuts.
[0051] The flexible connector 32 is provided with a third groove 323, the length direction of which is perpendicular to the length direction of the guide 2.
[0052] The length direction of the third groove 323 is perpendicular to the length direction of the guide member 2, that is, the length direction of the third groove 323 is parallel to the thickness direction of the guide member 2. In this way, the flexible connector 32 can adapt to the deformation of the guide member 2 in the thickness direction, so as to compensate for the positional deviation of the guide member 2 in the thickness direction.
[0053] There are at least two third grooves 323, which are spaced apart along the length of the flexible connector 32.
[0054] This further improves the adaptability of the flexible connector 32 to multiple deformations in the thickness direction of the guide member 2. It prevents multiple deformations in the thickness direction of the guide member 2 from causing the flexible connector 32 to be unable to adapt. The number of third grooves 323 can be increased or decreased according to the length of the guide member 2. When the guide member 2 is long, three, four, or even more can be set; conversely, when the guide member 2 is short, two are sufficient.
[0055] The third groove 323 is provided on the side of the flexible connector 32 near the guide member 2. In this way, the flexible connector 32 can be improved to adapt to the deformation of the guide member 2 in the thickness direction.
[0056] The supporting component 3 also includes a connecting plate 33, which is disposed on the side of the flexible connector 32 away from the carrier plate 31. The connecting plate 33 is connected to the guide 2, and the driving component 4 is connected to the connecting plate 33 in a transmission manner to drive the carrier plate 31 to move along the length direction of the guide 2.
[0057] The connecting plate 33 can be made of high-strength metal materials, such as high-quality steel or aluminum alloy, to ensure sufficient rigidity and stability. The connecting plate 33 prevents the guide component 2 and the drive component 4 from being directly connected to the carrier plate 31, which would result in multiple connection points on the carrier plate 31 and interfere with the carrier plate 31's ability to support the workpiece.
[0058] The carrier plate 31 is provided with several height adjustment supports 311, which are used to support the workpiece and adjust the levelness of the workpiece machining surface.
[0059] The height adjustment supports 311 can be evenly distributed on the carrier plate 31, or designed according to the size and shape of the workpiece. For example, for a rectangular workpiece, one height adjustment support 311 can be set at each of the four corners of the carrier plate 31; for larger or irregularly shaped workpieces, multiple height adjustment supports 311 can be evenly distributed on the carrier plate 31 to ensure stable support and horizontal adjustment of the workpiece.
[0060] The height-adjustable support 311 may include a support portion and an adjusting portion. One end of the adjusting portion is connected to the support portion, and the other end of the adjusting portion is threadedly connected to the carrier plate 31. Specifically, the adjusting portion may be a screw.
[0061] During use, the workpiece is first placed on the support platform of the carrier plate 31. By rotating the adjustment unit, the height of each height adjustment support 311 is adjusted, thereby changing the levelness of the workpiece's machined surface. Using a level or other measuring tools, the levelness of the workpiece's machined surface can be accurately detected, and fine adjustments can be made based on the detection results until the workpiece's machined surface reaches the required levelness. This design effectively ensures the stability of the workpiece during processing, improving machining accuracy and quality.
[0062] The worktable also includes a position detection component 5, which is connected to the carrier plate 31 to detect the displacement of the carrier plate 31.
[0063] The position detection component 5 can employ a high-precision position sensor, such as a linear encoder or a laser displacement sensor. The linear encoder is mounted on the connecting plate 33, and a read head is mounted on the guide 2 to detect the displacement of the carrier plate 31 on the guide 2 in real time; the laser displacement sensor detects the position of the carrier plate 31 by emitting a laser beam and measuring the displacement change of the reflected light.
[0064] During operation, the position detection component 5 monitors the displacement of the carrier plate 31 in real time and transmits the detected signal to the external control system. Based on the received displacement signal, the control system precisely controls and adjusts the movement position of the carrier plate 31. For example, when a deviation is detected between the actual displacement of the carrier plate 31 and the preset displacement, the control system can automatically adjust the motion parameters of the drive component 4 to return the carrier plate 31 to the correct movement path. This design effectively improves the movement accuracy of the carrier plate 31 and the level of automation control of the worktable, ensuring the processing accuracy and quality of workpieces such as OLED panels.
[0065] This application also provides a laser processing device, including the worktable described in any of the above embodiments.
[0066] The laser processing equipment of this application embodiment includes the worktable in any of the above embodiments, and therefore has the beneficial effects brought by the worktable in any of the above embodiments, which will not be repeated here.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
