Description

Technical Field

[0001] This invention relates to the field of edge exposure technology, and in particular to an edge exposure device for display panels. Background Technology

[0002] A display panel, also known as a screen or monitor panel, is a flat surface used to display images and information. It is typically composed of pixels (image units) that emit light or transmit light to produce images. It is a core component in various common electronic devices, including computer monitors, televisions, smartphones, tablets, and handheld game consoles.

[0003] Typically, edge exposure processing is required for display panels to remove photosensitive material from the edges, clearly and accurately defining the product boundaries. This facilitates contamination-free processing in subsequent steps and exposes the necessary cutting paths for cutting. Traditional edge exposure for display panels requires the use of photomasks to block out unexposed areas. However, photomasks are expensive and lack versatility; different panel sizes require specific photomasks, increasing processing costs and significantly reducing efficiency due to mask replacement.

[0004] There is an urgent need for an edge exposure device for display panels to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a display panel edge exposure device, which aims to improve the operating efficiency of the display panel edge exposure device and thereby increase the production capacity of the display panel production line.

[0006] To achieve the above objectives, the present invention proposes an edge exposure device for display panels, comprising an exposure machine tool, a stand, an exposure lamp, a base, and a feeding platform. The exposure machine tool is equipped with a slide rail, and sequentially has a loading position, an exposure position, and a unloading position along its extension direction. The stand is fixed to the exposure machine tool and is positioned corresponding to the exposure positions. The span direction of the stand is parallel to the width direction of the exposure machine tool, and the slide rail is located on the inner side of the stand. The exposure lamp is slidably connected to the crossbeam of the stand. The base is slidably connected to the slide rail. A feeding platform is used to place the display panel; the feeding platform is mounted on the base, and the base can drive the feeding platform to move back and forth to the loading position, the exposure position, and the unloading position.

[0007] Optionally, the crossbeam is provided with a guide groove, and the exposure lamp is slidably connected to the guide groove.

[0008] Optionally, the crossbeam is slidably connected to a plurality of the exposure lamps.

[0009] Optionally, the exposure lamp can adjust the light shape and / or the light range.

[0010] Optionally, the unloading position is provided with an unloading mechanism connected to the exposure machine tool, which is used to move the display panel from the unloading platform to other processing stations.

[0011] Optionally, the feeding mechanism is equipped with a magnetic wheel drive assembly.

[0012] Optionally, the exposure machine tool includes a lifting structure connected to the magnetic wheel drive assembly, the lifting structure being able to adjust the relative height between the magnetic wheel assembly and the feeding platform.

[0013] Optionally, the display panel edge exposure device is further provided with two clamping and straightening components arranged opposite to each other along the width direction of the exposure machine tool, and the clamping and straightening components are slidably connected to the exposure machine tool.

[0014] Optionally, the two clamping components are provided with limiting recesses opposite each other, the side of the limiting recesses is used to abut against the side edge of the display panel, and the height of the limiting recesses is greater than or equal to the thickness of the display panel.

[0015] Optionally, the base and / or the stand are configured to be made of marble.

[0016] Optionally, a driving unit is provided between the base and the feeding platform, and the driving unit drives the feeding platform to rotate along its plane.

[0017] Optionally, the feeding platform includes a support platform and several support members, the support members being connected to the support platform, and the display panel being placed on top of the support members; wherein the height of the support members is adjustable.

[0018] Optionally, the support includes a suction cup, a support body, and a height adjustment knob. The support includes a support body, a suction cup movably connected to the support body, and a height adjustment knob disposed between the support body and the suction cup. The height of the suction cup relative to the support platform can be adjusted by rotating the height adjustment knob.

[0019] In the technical solution of this invention, the edge exposure equipment for display panels does not require a photomask during the exposure process. The edge exposure of a display panel can be completed by moving the feeding platform and adjusting the relative position of the exposure lamps on the crossbeam. On one hand, the feeding platform can move its edge exposure area to the exposure position for exposure, while the non-exposure area is placed outside the exposure position during the exposure process. On the other hand, when the size of the display panel changes, the exposure lamps can adaptively adjust their relative position on the crossbeam so that the irradiation area corresponding to the exposure lamp corresponds to the edge exposure area of ​​the display panel. In summary, this edge exposure equipment for display panels reduces the production cost of edge exposure operations. Furthermore, this equipment is applicable to processing display panels of various sizes, improving the processing flexibility of the edge exposure equipment. Attached Figure Description

[0041] This invention proposes a display panel edge exposure device.

[0042] Reference Figures 1 to 8 In one embodiment of the present invention, the edge exposure device for the display panel includes: an exposure machine tool 100, a support frame 200, an exposure lamp 300, a base 400, and a feeding platform 500. The exposure machine tool 100 is provided with a slide rail 110, and a loading position 120, an exposure position 130, and a unloading position 140 are sequentially provided along the extending direction of the exposure machine tool 100. The support frame 200 is fixed to the exposure machine tool 100 and is arranged corresponding to the exposure position 130. The span direction of the support frame 200 and the exposure machine tool... The slide rails 110 are parallel in the width direction of the support frame 200; the exposure lamp 300 is slidably connected to the crossbeam 210 of the support frame 200; the base 400 is slidably connected to the slide rail 110; and the feeding platform 500 is used to place the display panel 10. The feeding platform 500 is mounted on the base 400, and the base 400 can drive the feeding platform 500 to move back and forth to the loading position 120, the exposure position 130 and the unloading position 140.

[0043] Specifically, the base 400 can move along the slide rail 110 on the exposure machine tool 100, so that the feeding platform 500 and the display panel 10 placed on the feeding platform 500 can move back and forth to the loading position 120, the exposure position 130 and the unloading position 140. The loading position 120 is used to place the display panel 10 on the feeding platform 500, the exposure position 130 is used to perform edge exposure on the display panel 10, and the unloading position 140 is used to place the display panel 10 after the exposure operation is completed. The exposure lamp 300 installed on the crossbeam 210 of the upright 200 can slide along the crossbeam 210 to adjust the relative position of the exposure lamp 300 and the feeding platform 500, so that the exposure lamp 300 can illuminate the working area of ​​the display panel 10 to be exposed.

[0044] For details, please refer to Figure 8 When the display panel 10 is rectangular, the specific operation process is as follows: When the first edge exposure area of ​​the display panel 10 moves to the exposure position 130, the exposure lamp 300 is turned on to expose the edge exposure area; after the first edge exposure area is exposed, the exposure lamp 300 is turned off, the base 400 moves, so that the second edge exposure area, which is opposite to the first edge exposure area, moves to the exposure position 130, and the exposure lamp 300 is turned on again to expose the second edge exposure area; after the second edge exposure area is exposed, the base 400 moves back to the loading position 120, and the display panel 10 is rotated 90° to switch the edge exposure area to be operated, and the third edge exposure area and the fourth edge exposure area, which are opposite to each other, are exposed in sequence (refer to the above steps for details). After the customs declaration operation is completed, the display panel 10 is moved to the unloading position 140. In this way, the edge exposure operation of the display panel 10 is completed.

[0045] It should be noted that the exposure lamp 300 can be adjusted to its relative position on the crossbeam 210 according to the size of the edge exposure area; when the display panel 10 is polygonal, the display panel 10 can be rotated at the loading position 120 according to the actual situation so that each edge exposure area of ​​the display panel 10 can complete the exposure operation.

[0046] In the technical solution of this invention, the edge exposure equipment for display panels does not require a mask during the exposure process. The edge exposure of a display panel 10 can be completed by moving the feeding platform 500 and adjusting the relative position of the exposure lamps 300 on the crossbeam 210. On one hand, the feeding platform 500 can move its edge exposure area to the exposure position 130 for exposure, while the non-exposure area is placed outside the exposure position 130 during the exposure process. On the other hand, when the size of the display panel 10 changes, the exposure lamps 300 can adaptively adjust their relative position on the crossbeam 210 of the support frame 200 so that the irradiation area corresponding to the exposure lamp 300 corresponds to the edge exposure area of ​​the display panel 10. In summary, this edge exposure equipment for display panels 10 can reduce the production cost of edge exposure operations. Furthermore, this edge exposure equipment is applicable to processing display panels 10 of various sizes, improving the processing flexibility and efficiency of the edge exposure equipment.

[0047] Specifically, the crossbeam 210 is provided with a guide groove 211, and the exposure lamp 300 is slidably connected to the guide groove 211. In this way, the exposure lamp 300 can move along the groove direction of the guide groove 211. The guide groove 211 needs to be set according to the position and exposure area of ​​the exposure position 130 so that the exposure lamp 300 can perform exposure work on the display panel 10 located on the exposure position 130 by moving on the guide groove 211.

[0048] In one embodiment, the crossbeam 210 is slidably connected to a plurality of exposure lamps 300 to further expand the exposeable area of ​​the display panel edge exposure device, enabling exposure of any area of ​​the display panel 10, thereby improving the processing flexibility and efficiency of the display panel edge exposure device.

[0049] In one embodiment, the exposure lamp 300 can adjust the shape and / or range of the light, so that the display panel edge exposure device can perform exposure operations of a specified shape and a specified area according to the exposure requirements of the display panel 10, thereby improving the processing flexibility and efficiency of the display panel edge exposure device.

[0050] In the above embodiments, the exposure lamp 300 can adopt a high energy density light source to simplify the edge exposure process, thereby improving the processing efficiency of the display panel edge exposure equipment, enabling the display panel edge exposure equipment to operate efficiently without occupying the overall production capacity of the display panel processing line.

[0051] In one embodiment, the unloading station 140 is correspondingly provided with an unloading mechanism 530 connected to the exposure machine tool 100. The unloading mechanism 530 is used to move the display panel 10 from the unloading platform 500 to other processing stations. Specifically, after the edge exposure operation of the display panel 10 is completed, the display panel 10 is moved to the unloading station 140. At this time, the unloading mechanism 530 is activated so that the display panel 10 can be moved to the next processing station with the unloading mechanism 530 for subsequent operations. In this way, the unloading mechanism 530 increases the functionality of the display panel edge exposure equipment. The display panel 10 does not need to be moved to the next processing station through an external mechanism. During the overall processing of the display panel 10, because the display panel edge exposure equipment integrates the unloading function, the floor space occupied by the equipment used for processing the display panel 10 is reduced to a certain extent. In other embodiments, the display panel 10 after edge exposure is completed is moved to the next processing station by an unloading robotic arm.

[0052] In one embodiment, the feeding mechanism 530 is equipped with a magnetic wheel transmission assembly. It should be understood that the magnetic wheel transmission assembly is a device that utilizes magnetic levitation technology to achieve power transmission and suspension support. The magnetic wheel assembly 531 operates with non-contact transmission; therefore, under ideal operating conditions, there is no friction or wear between the components of the magnetic wheel assembly 531, thereby reducing the maintenance rate and failure rate of the magnetic wheel assembly 531. Furthermore, because the magnetic wheel assembly 531 has no mechanical contact and no frictional loss, magnetic wheel transmission is generally more efficient, quieter, and has a longer lifespan than traditional mechanical transmission. Additionally, the rotational speed and torque of the magnetic wheel transmission can be precisely controlled by adjusting the strength of the magnetic field, thereby achieving precise motion control and positioning, and enabling zero-friction start-up.

[0053] In summary, the magnetic wheel assembly 531 makes the feeding mechanism 530 more efficient and has a longer service life. Furthermore, during the operation of the magnetic wheel assembly 531, no debris will be generated between the components due to mechanical contact, which meets the dust-free requirements in the edge exposure operation of the display panel 10, enabling the edge exposure equipment of the display panel to achieve dust-free transportation of the display panel 10.

[0054] In other embodiments, the feeding mechanism 530 is provided with a transmission gear assembly, in which the transmission of the display panel 10 is realized through the interlocking action between the driving wheel and the driven wheel.

[0055] Furthermore, the exposure machine tool 100 includes a lifting structure 532 connected to the magnetic wheel transmission assembly. The lifting structure 532 can adjust the relative height between the magnetic wheel assembly 531 and the unloading platform 500. Specifically, when the size of the display panel 10 is large, the edge of the display panel 10 will fall onto the plane of the unloading platform 500 due to the weight of the panel itself. The deformation of the edge of different sized display panels 10 will vary. Therefore, in actual processing, the magnetic wheel transmission assembly can adjust its relative height to the unloading platform 500 through the lifting structure 532, making the transmission surface of the magnetic wheel transmission assembly flush with or lower than the plane of the edge of the display panel 10. This reduces interference from the lateral structure of the magnetic wheel assembly 531 on the edge of the display panel 10, avoids jamming during the unloading process of the display panel 10, improves the flexibility of the exposure equipment for the display panel edge, and achieves efficient processing of the display panel 10.

[0056] In one embodiment, the display panel edge exposure device is further provided with two clamping assemblies 600 arranged opposite to each other along the width direction of the exposure machine tool 100, and the clamping assemblies 600 and the exposure machine tool 100 are slidably connected. It should be noted that during the edge exposure process of the entire display panel 10, since the display panel 10 is attached to the feeding platform 500 and moves with the feeding platform 500 on the exposure machine tool 100, the display panel 10 may be misaligned relative to the feeding platform 500 due to the start-up, stop, and vibration of the feeding platform 500 during the movement operation. The aforementioned clamping and straightening component 600 is used to adjust the display panel 10. Once the display panel 10 is misaligned relative to the feeding platform 500, the clamping and straightening component 600, through its contact with the edge of the display panel 10, restores the display panel 10 to the correct position on the feeding platform 500, so that the display panel 10 can be placed directly opposite the feeding platform 500. In this way, the edge exposure area of ​​the display panel 10 can be aligned with the exposure position 130, improving the edge exposure accuracy of the display panel 10.

[0057] Furthermore, the two clamping components 600 are set corresponding to the aforementioned unloading position 140. Thus, when the unloading platform 500 moves from the unloading position 140 to the exposure position 130, the display panel 10 can be placed upright on the unloading platform 500 by the limiting effect of the two clamping components 600, so that the edge of the display panel 10 can be aligned with the exposure position 130 and the edge exposure operation can be completed more accurately.

[0058] More specifically, the two clamping components 600 are provided with limiting recesses 610 opposite to each other. The side of the limiting recess 610 is used to abut against the side edge of the display panel 10. The height of the limiting recess 610 is greater than or equal to the thickness of the display panel 10. In this way, the display panel 10 can be corrected by the mutual abutment between itself and the limiting recess 610. The limiting recess 610 also has a certain avoidance function for the display panel 10. When the distance between the two clamping components 600 is less than the length or width of the display panel 10, the display panel 10 can move between the two clamping components 600 through the limiting recess 610.

[0059] In other embodiments, the two clamping components 600 are slidably connected to the exposure machine tool 100 so that the distance between the two clamping components 600 can be adjusted.

[0060] In one embodiment, the base 400 and / or the stand 200 are configured to be made of marble. Because marble has high hardness and good stability, its deformation is very weak after long-term use. Using a marble base 400 and / or stand 200 can improve the operating accuracy and service life of the display panel edge exposure equipment.

[0061] In other embodiments, the base 400 is understood to be configured as a stainless steel component.

[0062] In one embodiment, a driving unit 900 is provided between the base 400 and the feeding platform 500. The driving unit 900 drives the feeding platform 500 to rotate along its plane. Thus, when the feeding platform 500 returns from the exposure position 130 to the loading position 120, the driving unit 900 can drive the plane of the feeding platform 500 to rotate, so that another edge to be exposed can move to the exposure position 130 for edge exposure. This improves the intelligence of the display panel edge exposure device.

[0063] In other embodiments, the base 400 and the feeding platform 500 are fixedly connected. When the feeding platform 500 returns from the exposure position 130 to the loading position 120, the user manually rotates the display panel 10 to change the edge exposure operation area 511 of the display panel 10.

[0064] In one embodiment, the feeding platform 500 includes a support platform 510 and several support members 520. The support members 520 are connected to the support platform 510, and the display panel 10 is placed on top of the support members 520. The height of the support members 520 is adjustable, allowing the user to adjust them according to the actual curvature of the display panel 10, ensuring they fit appropriately. Specifically, when the display panel 10 has a curvature, the user can adjust each support member 520 to form a support surface with the same curvature as the display panel 10 at its top. When the display panel 10 needs to maintain a high-precision flatness, the user can adjust each support member 520 to form a high-precision plane at its top.

[0065] It is worth mentioning that when the display panel 10 needs to maintain a high-precision flatness, the slight deformation of the support platform 510 due to its own weight will also affect the processing effect of the display panel 10. At this time, the various support members 520 can be adjusted accordingly based on the actual deformation of the support platform 510 so that the top of the support member 520 can form a high-precision plane.

[0066] In one embodiment, the support member 520 includes a support body 522, a suction cup 521 movably connected to the support body 522, and a height adjustment knob 523 disposed between the support body 522 and the suction cup 521. By rotating the height adjustment knob 523, the height of the suction cup 521 relative to the support platform 510 can be adjusted. Thus, when the display panel 10 is too large, the support member 520 can use the suction effect of the suction cup 521 to make the display panel 10 abut against the top of each support member 520, and can maintain relative stillness with the support platform 510 as the display panel 10 moves with the support platform 510. The height adjustment knob 523 allows the user to adjust the height of the support member 520 by rotating the knob, which is convenient for user operation and improves the usability of the support member 520.

[0067] In other embodiments, the user adjusts the distance between the suction cup 521 and the support platform 510 by pulling the suction cup 521 up and down.

[0068] Furthermore, the outer surface of the height adjustment knob 523 is marked with scales to help the user perceive the lifting height of the suction cup 521.

[0069] The present invention also proposes a display panel 10 processing apparatus, which includes a frame, a robotic arm, and a display panel edge exposure device. The specific structure of the display panel edge exposure device is as described in the above embodiments. Since this display panel 10 processing apparatus adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The robotic arm and the display panel edge exposure device are both connected to the frame.

[0070] For further details, please refer to [link / reference]. Figure 6The support platform 510 is provided with multiple spaced-apart working areas 511, and the support member 520 is arranged in the working areas 511. Multiple clearance paths 512 are formed between the multiple working areas 511. The robotic arm is provided with a claw 700 for transporting the plate to the support platform 510. The claw 700 is provided with multiple spaced-apart and parallel teeth 710. When the claw 700 transports the plate to the support platform 510, one tooth 710 can be placed in a corresponding clearance path 512. That is, after the display panel 10 is placed on top of the support member 520, the claw 700 of the robotic arm can move relatively close to the support platform 510 to leave the surface of the display panel 10, and then move and be pulled out along the extension direction of the clearance path 512. Thus, during the movement of the display panel 10 by the robotic arm, the teeth 710 on its claw 700 can form a large support surface, which supports the display panel 10 to reduce physical deformation of the display panel 10. On the other hand, the teeth 710 of the robotic arm can move accordingly in the height direction of the clearance passage 512, so that the display panel 10 can be stably placed on top of the multiple support members 520, improving the ease of use of the display panel 10 processing device.

[0071] In one embodiment, a detection camera 800 is connected to the edge of the support platform 510. The detection camera 800 is used to detect the relative position between the display panel 10 and the support platform 510. Specifically, the user can first mark the edge of the display panel 10. The detection camera 800 captures the distance between the mark and the edge of the support platform 510 to help determine the actual placement position of the display panel 10 and whether subsequent adjustments to the placement position of the display panel 10 are needed. It should be noted that when the size of the display panel 10 is small and can be fully placed on the support platform 510, there may be a situation where the detection camera 800 cannot capture the display panel 10. In this case, multiple detection cameras 800 can be set at multiple edges and multiple positions of the support platform 510, and the actual placement effect of the display panel 10 can be comprehensively determined by combining the shooting conditions of each detection camera 800.

[0072] In other embodiments, a detection camera 800 is provided above the support platform 510. The detection camera 800 takes a top-down picture of the actual effect of the display panel 10 after it is placed on the support platform 510, and assists in detecting the relative position between the display panel 10 and the support platform 510.

[0073] Please refer to further details. Figures 7 to 11The present invention also proposes a processing technology for edge exposure of display panel 10. This processing technology is applied to the above-mentioned display panel edge exposure equipment. The specific structure of the display panel edge exposure equipment is as described in the above embodiments. Since the display panel 10 processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] Specifically, such as Figure 9 As shown, the processing steps for edge exposure of the display panel 10 are as follows:

[0075] S0: Place the display panel 10 on the feeding platform 500 and start the edge exposure device of the display panel;

[0076] S1: The feeding platform 500 moves from the feeding position 120 to the exposure position 130;

[0077] S2: When one edge of the display panel 10 moves to the exposure position 130, the exposure lamp 300 is turned on to perform the exposure operation on that edge;

[0078] S3: After the exposure operation at this edge is completed, turn off the exposure lamp 300;

[0079] S4: Determine the number of remaining edges to be exposed;

[0080] When the number of remaining unexposed edges is greater than 1:

[0081] S5: Move the material feeding platform back 500 to the first position 150;

[0082] S6: Rotate the display panel 10 to switch the edge to be exposed, and then perform the above steps S1-S4 until the number of remaining edges to be exposed is equal to 1.

[0083] S7: After the last exposure with the exposed edge is completed, turn off the exposure lamp 300;

[0084] S8: Move the feeding platform 500 to the unloading position 140.

[0085] It should be noted that the first position 150 is located between the loading position 120 and the exposure position 130 and / or the first position 150 is the loading position 120.

[0086] Further, please refer to Figure 10 When the display panel 10 is a symmetrical shape, the above step S2 can be further specified:

[0087] S21: When the first edge of the display panel 10 moves to the exposure position 130, the exposure lamp 300 is turned on to perform the exposure operation on the first edge;

[0088] S22: When the first edge exposure is complete, turn off the exposure lamp 300;

[0089] S23: Continue to move the material feeding platform 500 meters to the side where the material position 140 is located;

[0090] S24: When the second edge of the display panel 10 moves to the exposure position 130, the exposure lamp 300 is turned on to complete the exposure operation on the second edge.

[0091] It should be noted that the first edge and the second edge refer to the two edges that are arranged opposite to each other on the display panel 10; it should be understood that during the rotation of the display panel 10, the user can determine the rotation angle based on the included angle between the edge areas of the display panel 10 to be exposed; it should also be noted that the second position 160 is located between the exposure position 130 and the unloading position 140 and / or the second position 160 is the unloading position 140.

[0092] Further, please refer to Figure 11 When a drive unit 900 capable of driving the feeding platform 500 to rotate is provided between the base 400 and the feeding platform 500, the above step S4 can be further specified:

[0093] S61: The user inputs the rotation angle from the control panel, and then the automatic control system of the exposure device at the edge of the panel is activated.

[0094] S62: The drive unit is in the rotation state, driving the feeding platform to rotate 500 degrees.

[0095] S63: The feeding platform 500 rotates to the specified rotation angle, and the drive unit shuts off the rotation state.

[0096] This automates the edge exposure equipment for display panels, reduces manual intervention, and thus improves the production efficiency of the edge exposure equipment for display panels.

[0097] Further, please refer to Figure 12 The edge exposure device of the display panel 10 is connected to the edge of the support platform 510 with a detection camera 800. The detection camera 800 is used to detect the relative position between the display panel 10 and the support platform 510. Therefore, the above-mentioned processing step S0 can be further refined. The specific operation steps are as follows:

[0098] S01: Place the display panel 10 on the feeding platform 500;

[0099] S02: Start the detection camera 800 to take pictures of the edge of the feeding platform 500;

[0100] S03: Determine whether it is necessary to adjust the position of the display panel 10 relative to the feeding platform 500 based on the shooting results of the detection camera 800;

[0101] If adjustment is required, proceed to step S04: adjust display panel 10, and then continue with the above steps S02-S03 until the shooting structure of the camera 800 shows that no adjustment of display panel 10 is required.

[0102] S05: Start the display panel edge exposure device.

[0103] In this way, the display panel 10 can be placed stably on the feeding platform 500, and thus the display panel 10 can be placed directly opposite the feeding platform 500, thereby improving the edge exposure effect of the display panel 10.

[0104] Furthermore, since the exposure effect of the display panel 10 is strongly correlated with the irradiation time of the exposure lamp 300, and in order to further accelerate the exposure efficiency of the display panel 10, when the exposure lamp 300 irradiates the edge exposure area of ​​the display panel 10, the feeding platform 500 can transport and drive the display panel 10 to move, so that each surface area of ​​the edge exposure area of ​​the display panel 10 can receive the irradiation of the exposure lamp 300, thereby completing the edge exposure operation of the display panel 10.

[0105] Based on the above embodiments, considering that during the movement of the display panel 10, the display panel 10 changes from a stopped state to a uniform speed movement state, and there is an acceleration movement state for a certain period of time, a first preparatory moving section can be added in the above S1 step. When the display panel 10 is placed at the loading position 120 and / or the first position 150, the first preparatory moving section is sandwiched between the display panel 10 and the exposure position 130. When the edge exposure area of ​​the display panel 10 enters the exposure position 130 for exposure operation through the first preparatory moving section, the unloading platform 500 has entered a uniform speed movement state. At this time, the edge exposure area of ​​the display panel 10 can pass through the exposure position 130 at a uniform speed, so that the exposure effect of each surface area of ​​the edge exposure area of ​​the display panel 10 is the same, thereby improving the exposure effect of the display panel 10.

[0106] Similarly, when the feeding platform 500 moves from the second position 160 to the exposure position 130, a second pre-moving segment can be set between the exposure position 130 and the second position. When the display panel 10 is in the second position 160, the second pre-moving segment is sandwiched between the display panel 10 and the exposure position 130. When the edge exposure area of ​​the display panel 10 enters the exposure position 130 for exposure operation through the second pre-moving segment, the feeding platform 500 has entered a uniform speed movement state. At this time, the edge exposure area of ​​the display panel 10 can pass through the exposure position 130 at a uniform speed, so that the exposure effect of each surface area of ​​the edge exposure area of ​​the display panel 10 is the same, thereby improving the exposure effect of the display panel 10.

[0107] In other embodiments, the edge exposure effect of the display panel 10 can be ensured by controlling the illumination duration of the exposure lamp 300. Specifically, when the first edge of the display panel 10 is a certain distance away from the exposure position 130, the exposure lamp 300 is turned on to ensure that each surface area of ​​the first edge exposure area can complete the exposure operation; when the display panel 10 moves back from the second position 160 to the first position 150, when the second edge of the display panel 10 is a certain distance away from the exposure position 130, the exposure lamp 300 is turned on to ensure that each surface area of ​​the second edge exposure area can complete the exposure operation.

[0108] It should be noted that the above distance can be set by the user, or by setting a sensor on the exposure machine tool 100 to sense the relative position of the edge exposure area and the exposure position 130, so as to control the opening and closing of the exposure lamp 300.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
