Description

Technical Field

[0001] This invention relates to the field of display panel processing technology, and in particular to a panel cutting and forming equipment for display modules. Background Technology

[0002] As display technology develops towards larger sizes, higher resolutions, and greater flexibility, the glass substrate used as raw material often sags or bulges in certain areas during the cutting of large-size display panels due to its own weight, defects in the raw materials, or errors in the equipment. Existing equipment can only provide passive support and lacks targeted movement compensation functions, which prevents the initial surface of the display panel from remaining level. This results in insufficient cutting depth or uneven cut surfaces, thereby reducing processing accuracy and affecting yield. Summary of the Invention

[0003] The main objective of this invention is to provide a panel cutting and forming equipment for display modules, which aims to solve existing technical problems.

[0004] To achieve the above objectives, the present invention provides a panel cutting and forming equipment for display modules, comprising: A processing table used to place panels; A cutting device, located above the processing table, is used for cutting panels; Testing agency, used to test the flatness of panel surface; The dynamic compensation component includes a guide mechanism, a power base on the guide mechanism, a lifting mechanism on the power base, a bracket on the lifting mechanism, a mounting cylinder at the top of the bracket, and a first micro-column platform that can be actively raised and lowered inside the mounting cylinder. The first micro-column platform keeps the panel flush by contacting the panel and generating a thrust or suction force.

[0005] Furthermore, the first micro-pillar platform is provided with uniformly distributed micro-pillars, each of which is movably inserted into an independent guide post. The top of the guide post is provided with an elastic element connected to the micro-pillar, and the guide post is provided with a channel. The air inlet end of the channel is connected to an air pump group, and the air outlet end abuts against the inner wall of the micro-pillar. Injecting air into the channel causes the micro-pillar to move upward along the guide post and generate thrust. The top of the micro-column has evenly distributed pores, which are opened or closed by a movable sealing element to draw air into the channel and generate suction at the pores.

[0006] Furthermore, the inner wall of the micro-cylinder has a groove for the movement of the sealing element, the groove has an elastic element connected to the sealing element, and the end of the sealing element has a protrusion. The guide post has a pusher portion at its top that contacts the protrusion. When the top of the guide post contacts the inner wall of the micro-pillar, the pusher portion contacts the protrusion and pushes the seal to move, thereby controlling the opening of the air hole.

[0007] Furthermore, the top of the micro-pillar has a rubber layer, and the rubber layer has pores communicating with air pores.

[0008] Furthermore, the bracket is fitted with an annular seat, the surface of which is provided with a guide groove, and a slide rail is provided on the outer side of the annular seat. One end of the slide rail is movably connected to the guide groove and the other end is suspended. A moving block is provided on the slide rail, and a second micro-column platform is provided on the moving block. A toggle member is provided below the slide rail, and the toggle member can rotate around the bracket to drive the slide rail to rotate.

[0009] Furthermore, the bracket is provided with a diagonal brace that is connected to the slide rail.

[0010] Furthermore, the guiding mechanism includes two first guide rails, with a second guide rail between the two first guide rails. A slider is provided on the first guide rail, and a lifting mechanism connected to the second guide rail is provided on the slider.

[0011] Furthermore, the processing table is provided with two processing stations, and an output mechanism is provided on the upper side of the processing table, with a guide rail between the output mechanism and the processing table; The output mechanism and the guide rail are controlled by a drive mechanism to move synchronously between the two processing stations.

[0012] Furthermore, the detection mechanism includes a substrate disposed below the processing table, on which sensors are uniformly distributed.

[0013] Furthermore, the power base is provided with power wheels at both ends, the power wheels are driven by a motor, and the second guide rail is provided with guide grooves adapted to the power wheels.

[0014] The beneficial effects of this invention are reflected in: This invention uses an active dynamic compensation component to compensate for local sagging or bulging areas on the panel, keeping the panel surface flat. This avoids problems such as insufficient cutting depth or uneven cutting surfaces caused by local deformation of the surface during the cutting process, thus improving cutting quality and yield.

[0015] This invention uses multiple independently moving micro-pillars to better address panel deformation and provides multi-point compensation for each deformation point. This ensures effective compensation while avoiding stress concentration damage to the panel.

[0016] This invention utilizes the cooperation of micro-pillars and guide pillars to achieve dynamic compensation for sagging parts of the panel by having the micro-pillars rise to provide thrust and the micro-pillars descend to provide suction to dynamically compensate for raised parts of the panel. This results in higher integration, a simpler structure, and dynamic compensation for deformed parts of the panel.

[0017] By setting up a first micro-pillar platform and a second micro-pillar platform, and cooperating with a second guide rail and a guide rail, this invention can not only dynamically compensate for multiple deformation points on the panel, but also stably support and transport the cut panel to the subsequent work station. In other words, it not only satisfies the multi-point compensation of the panel, but also avoids the problem of panel damage during transportation through support and transportation.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, 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 invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 The present invention provides a panel cutting and forming equipment for display modules, including a processing table 100 for placing panels; The cutting device 200 is located above the processing table 100 and is used to cut the panel; specifically, the cutting device 200 adopts existing laser cutting equipment.

[0022] Testing unit 300 is used to test the flatness of the panel surface; The dynamic compensation component 400 includes a guide mechanism 401, a power base 402 on the guide mechanism 401, the power base 402 being able to move actively on the guide mechanism 401, a lifting mechanism 404 on the power base 402, and a bracket 403 on the lifting mechanism 404. Specifically, the lifting mechanism 404 can be a cylinder. The top of the bracket 403 is provided with a mounting cylinder 405, and a first micro-column platform 406 that can be actively lifted and lowered is provided inside the mounting cylinder 405. The first micro-column platform 406 keeps the panel flush by contacting the panel and generating a pushing or suction force.

[0023] In this embodiment, after the panel to be cut is placed on the processing table 100, the flatness of the panel surface is detected by the detection mechanism 300. Based on the feedback detection data, the deformed parts of the panel are determined. The first micro-pillar platform 406 is moved to the underside of the deformed parts. Dynamic compensation is achieved through the active lifting action of the first micro-pillar platform 406. That is, the first micro-pillar platform 406 provides thrust when it rises to dynamically compensate for the sagging parts on the panel, and provides suction when it falls to dynamically compensate for the raised parts on the panel.

[0024] This invention uses an active dynamic compensation component 400 to compensate for local sagging or bulging areas on the panel, keeping the panel surface flat. This avoids problems such as insufficient cutting depth or uneven cutting surfaces caused by local panel deformation during the cutting process, thus improving cutting quality and yield.

[0025] In one embodiment, the first micro-pillar platform 406 is provided with uniformly distributed micro-pillars 4061, each micro-pillar 4061 being movably inserted into an independent guide post 4062. The top of the guide post 4062 is provided with an elastic element 4063 connected to the micro-pillar 4061. Specifically, the elastic element 4063 can be a spring. In the initial state, there is a gap between the top of the guide post 4062 and the inner top wall of the micro-pillar 4061.

[0026] The guide column 4062 has a channel 40621 inside. The air inlet end of the channel 40621 is connected to the air pump group 4064, and the air outlet end abuts against the inner wall of the micro column 4061. Injecting air into the channel 40621 causes the micro column 4061 to move upward along the guide column 4062, generating thrust. Specifically, the air pump group 4064 includes an air pump and an air pump. The air pump group 4064 is connected to each channel 40621 through an independent air pipe, and each air pipe is equipped with a control valve.

[0027] The top of the micro-pillar 4061 has evenly distributed pores 40611. The pores 40611 are opened or closed by a movable seal 4065 to draw air into the channel 40621, thereby generating suction at the pores 40611.

[0028] In this embodiment, when the first micropillar platform 406 is moved below the deformed portion of the panel, depending on the type of panel deformation, if the deformed portion is drooping, gas is injected into the channel 40621 via the air pump assembly 4064. The gas enters the micropillar 4061 from the top of the guide column 4062, pushing the micropillar 4061 upward until it contacts the panel. The evenly distributed micropillars 4061 sequentially adapt and abut against different positions of the deformed portion of the panel, according to the different positions of the deformed portion. The variable controls the upward movement of each micro-pillar 4061 by a corresponding distance to compensate for the sagging parts of the panel. If the deformed part is bulging, the air pump group 4064 pumps air into the channel 40621, so that the air holes 40611 on the micro-pillar 4061 are under negative pressure, which generates suction on the deformed part of the panel, causing the micro-pillar 4061 to move downward along the guide post 4062 to compensate for the bulging part of the panel. This achieves multi-point dynamic compensation for the deformed part and improves the subsequent cutting quality.

[0029] In this implementation, multiple independently moving micro-pillars 4061 are set up to better handle the deformed parts of the panel. Multi-point compensation is performed on each deformed part, which can not only ensure the compensation effect, but also avoid the problem of stress concentration damaging the panel.

[0030] In one embodiment, the inner wall of the micro-pillar 4061 has a groove 40612 for the movement of the sealing member 4065. A reset member 4066 connected to the sealing member 4065 is provided within the groove 40612. The sealing member 4065 has a protrusion 40651 at its end. Specifically, the sealing member 4065 has a through hole corresponding to the vent 40611. When the vent 40611 is misaligned with the through hole, the vent 40611 is in a closed state. Specifically, the reset member 4066 is a spring.

[0031] The guide post 4062 has a pusher 40622 at its top that contacts the protrusion 40651. When the top of the guide post 4062 contacts the inner wall of the micro-pillar 4061, the pusher 40622 contacts the protrusion 40651, pushing the seal 4065 to move and controlling the air hole 40611 to open.

[0032] In this embodiment, when air is injected into the channel 40621, the micro-pillar 4061 moves upward relative to the guide post 4062. At this time, the pushing part 40622 separates from the protrusion 40651, and the air hole 40611 is in a closed state. When air is drawn out of the channel 40621, the micro-pillar 4061 moves downward relative to the guide post 4062 until the pushing part 40622 contacts the protrusion 40651, pushing the protrusion 40651 to drive the sealing member 4065 to move, so that the through hole on the sealing member 4065 communicates with the air hole 40611, and the air hole 40611 is in an open state. At this time, the air hole 40611 is in a negative pressure state, generating suction on the deformed part of the panel, thereby compensating for the raised part of the panel.

[0033] In one embodiment, the top of the micropillar 4061 has a rubber layer with pores communicating with the air pores 40611.

[0034] In this embodiment, the micro-pillar 4061 can achieve soft contact with the panel through the rubber layer, which can not only maintain effective contact with the curved surface of the panel deformation part, but also protect the panel from damage and improve the subsequent cutting quality.

[0035] In one embodiment, a ring seat 407 is fitted onto the bracket 403. A guide groove is formed on the surface of the ring seat 407, and a slide rail 408 is provided on the outer side of the ring seat 407. One end of the slide rail 408 is movably connected to the guide groove, and the other end is suspended. A moving block 409 is provided on the slide rail 408, and a second micro-pillar platform 410 is provided on the moving block 409. Specifically, the second micro-pillar platform 410 has the same structure as the first micro-pillar platform 406. Specifically, the moving block 409 is provided with a moving wheel driven by a motor, and the moving wheel moves within a groove formed on the slide rail 408.

[0036] A toggle element 411 is provided below the slide rail 408. The toggle element 411 can rotate around the bracket 403 to drive the slide rail 408 to rotate. Specifically, the toggle element 411 is fixed on the gear ring, which is movably sleeved on the bracket 403. The gear ring is driven by a stepper motor and gears. The toggle element 411 is an electric telescopic rod.

[0037] In this embodiment, when there are multiple deformable parts on the panel, the sliding rail 408 is rotated around the annular seat 407 by the toggle member 411, and the moving block 409 moves along the sliding rail 408 to drive the second micro-column platform 410 to move below the deformable parts, thereby realizing the active dynamic compensation operation of the multi-point deformable parts on the surface and improving efficiency.

[0038] Preferably, four slide rails 408 are provided, which can not only meet the limited multi-point dynamic compensation, but also provide stable support for subsequent support and transfer of the panel.

[0039] In one embodiment, the bracket 403 is provided with a diagonal brace 412 connected to the slide rail 408. In this embodiment, the diagonal brace 412 ensures high stability while guaranteeing that the slide rail 408 can connect with the subsequent guide rail 501.

[0040] In this embodiment, when the second micro-pillar platform 410 is separated from the first micro-pillar platform 406, active dynamic compensation can be performed on the multi-point deformed parts on the panel. When the second micro-pillar platform 410 is spliced ​​with the first micro-pillar platform 406, active dynamic compensation can be performed on the large-area deformation of the panel. It has a wide range of applications and meets more needs.

[0041] In one embodiment, the guiding mechanism 401 includes two first guide rails 4011, with a second guide rail 4012 disposed between the two first guide rails 4011. A slider 4013 is disposed on each of the first guide rails 4011, and a lifting mechanism 4014 connected to the second guide rail 4012 is disposed on the slider 4013. Specifically, the first guide rails 4011 are electric guide rails; the lifting mechanism 4014 is a hydraulic cylinder.

[0042] In this embodiment, based on the deformation position on the panel, the second guide rail 4012 is first moved along the first guide rail 4011, and then the power base 402 is moved along the second guide rail 4012 until the first micro-pillar platform 406 is moved below the deformation position. Then, based on the number of deformation parts, the second micro-pillar platform 410 is selected for active dynamic compensation.

[0043] In one embodiment, the processing table 100 is provided with two processing stations 101, and an output mechanism 500 is provided on the upper side of the processing table 100, with a guide rail 501 between the output mechanism 500 and the processing table 100. The output mechanism 500 and the guide rail 501 are controlled by the drive mechanism 502 to move synchronously between the two processing stations 101. Specifically, the drive mechanism 502 can be an electric actuator. A support plate (not shown in the figure) is provided below the guide rail 501, and the guide rail 501 is slidably connected to the support plate.

[0044] In this embodiment, after the panel is cut, the lifting mechanism 4014 drives the second guide rail 4012 to rise until it reaches the same height as the guide rail 501. Then, the guide rail 501 is driven to connect with the second guide rail 4012, allowing the power base 402 to move along the second guide rail 4012 onto the guide rail 501. This then transports the cut panel to the output mechanism 500. The lifting mechanism 404 then places the panel on the output mechanism 500 for transport to subsequent processing equipment. This avoids the risk of stress concentration and panel damage that can occur with traditional single-point suction cups or clamps for panel transfer. This invention, through full-process support and multi-point support, achieves stable transmission and avoids the risk of panel damage.

[0045] In this embodiment, by setting two processing stations 101, the panel can be processed alternately, avoiding the problem of long waiting time when a single station transmits the panel to the next stage, thus ensuring processing efficiency; specifically, each processing station 101 is connected to an independent output mechanism 500.

[0046] In one embodiment, the detection mechanism 300 includes a substrate 301 disposed below the processing table 100, on which sensors 302 are uniformly distributed. Specifically, the sensors 302 may be laser sensors.

[0047] In this embodiment, densely distributed sensors 302 detect the deformed parts on the panel and output detection data, thereby providing data support for the subsequent dynamic compensation component 400, driving the dynamic compensation component 400 to move to the deformed part to perform active compensation.

[0048] In one embodiment, the power base 402 is provided with power wheels 4021 at both ends. The power wheels 4021 are driven by a motor, and the second guide rail 4012 is provided with guide grooves adapted to the power wheels 4021.

[0049] In this embodiment, the power base 402 can be driven to move actively along the second guide rail 4012 by the power wheel 4021. Alternatively, when the panel is transferred and transported in the future, the power base 402 can be moved from the second guide rail 4012 to the guide rail 501 to realize the transfer of the panel.

[0050] It should be noted that if the embodiments of the present invention 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.

[0051] Furthermore, if the embodiments of this invention 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 technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
