Description

Technical Field

[0001] The present application relates to the technical field of display panels, and in particular to a single-point support structure, a support component and a processing device. Background Art

[0002] Inkjet printing has been used in the manufacturing process of existing OLED devices or QLED devices. Some functional materials can be printed by inkjet printing, for example, the hole injection layer (HIL), hole transport layer (HTL), light-emitting layer material (EML) and other functional materials can be printed by inkjet printing, and other functional layers that can be printed by inkjet are also applicable. That is, for the existing pixel pits, the functional layer material ink is injected into the pixel pits by inkjet printing.

[0003] For various factors affecting the efficiency of OLED devices, the uniformity of film formation of each functional layer material is a very important consideration. Generally, vacuum drying equipment is used to dry the substrate to form a film.

[0004] In the related art, some vacuum drying equipment adopts a combination of an ejector assembly and a carrier plate. The ejector assembly includes an ejector plate and a plurality of ejectors. The plurality of ejectors are fixed on the ejector plate. The ejectors pass through the carrier plate, and the carrier plate or the ejector plate can be raised and lowered. The substrate is supported at multiple points by multiple ejectors, so that the substrate is suspended on the carrier plate, and it is convenient to lift the substrate from below. When the substrate is dried, the carrier plate rises relative to the ejectors, and the substrate is supported by the carrier plate. In some vacuum drying equipment, multiple ejectors are directly used to support the substrate at multiple points, so that it is convenient to lift the substrate from below.

[0005] However, when the substrate is supported by the combination of the ejector assembly and the carrier plate, due to the large number of ejector pins and the need to pass through the carrier plate, there is a tendency for the positions of some ejector pins to deviate from the positions of the openings on the carrier plate, causing the ejector pins to get stuck on the carrier plate; and when supporting a large-sized substrate, the substrate needs to be supported in a form where the ends are slightly higher and the center is slightly lower to facilitate the subsequent separation of the substrate and the ejector pins. Therefore, the ejector pins will be subjected to lateral forces exerted by the substrate, causing the ejector pins to become skewed and stuck on the carrier plate. Since the ejector pins are stuck on the carrier plate, the lifting and lowering of the carrier plate is affected, and the ejector pins are easily damaged, resulting in poor support effects and short support life of the ejector pins. Summary of the invention

[0006] The embodiments of the present application provide a single-point support structure, a support assembly, and a processing device to solve the technical problem in the related art that the ejector pin and the carrier plate are easily stuck, which affects the lifting and lowering of the carrier plate and easily damages the ejector pin, resulting in poor support effect of the ejector pin and short support life.

[0007] In a first aspect, a single-point support structure is provided, which is used to be installed on a base plate and a bearing plate, wherein the bearing plate is located above the base plate and the bearing plate is arranged to be lifted and lowered, and the single-point support structure comprises:

[0008] An ejector pin, the ejector pin is used to penetrate the carrying plate, and the carrying plate is suitable for rising relative to the ejector pin so that the top surface of the carrying plate is higher than the ejector pin;

[0009] A guide sleeve, wherein the guide sleeve is mounted on the bearing plate, and the ejector pin is inserted through the guide sleeve, and a gap is left between the circumferential outer side surface of the ejector pin and the circumferential inner side surface of the guide sleeve;

[0010] The adjusting sleeve is used to be inserted into the bottom plate, and the adjusting sleeve is lifted and lowered on the bottom plate. The adjusting sleeve includes a supporting inner bottom surface, the bottom end of the ejector pin extends to the adjusting sleeve, and the bottom end of the ejector pin abuts against the supporting inner bottom surface.

[0011] In some embodiments, the single-point support structure further includes a limiting member, the limiting member is connected to the ejector pin, the limiting member is arranged close to the bottom end of the ejector pin, and the limiting member is located in the adjustment sleeve;

[0012] The adjusting sleeve comprises a limiting inner top surface, and a gap is left between the limiting member and the limiting inner top surface;

[0013] Wherein, as the limiting member and the ejector pin rise, the limiting member is adapted to approach and press against the inner top surface of the limiting member.

[0014] In some embodiments, the limiting member includes a limiting plate and a limiting nut, the circumferential side of the ejector pin is provided with a step surface, the limiting plate is sleeved on the ejector pin, the limiting nut is threadedly connected to the ejector pin, and the limiting plate is clamped between the step surface and the limiting nut.

[0015] In some embodiments, the bottom end of the ejector pin is arranged in a ball head shape so that the ejector pin is in point contact with the inner bottom surface of the support.

[0016] In some embodiments, the adjustment sleeve is threadedly connected to the base plate, and the height of the adjustment sleeve relative to the base plate is changed by rotating the adjustment sleeve relative to the base plate.

[0017] In some embodiments, the adjustment sleeve comprises:

[0018] A sleeve body, the sleeve body is inserted through the bottom plate, a through hole for the ejector pin to pass through is opened at the top of the sleeve body, and the bottom surface of the sleeve body is open;

[0019] The cover body is installed on the bottom surface of the sleeve body to block the bottom end of the sleeve body, and the top surface of the cover body is the supporting inner bottom surface.

[0020] In some embodiments, an operating groove is arranged on the bottom surface of the cover body.

[0021] In some embodiments, the single-point support structure further includes a support head, and the support head is sleeved on the top end of the ejector pin.

[0022] The embodiment of the present application provides a single-point support structure. Generally, multiple single-point support structures are used to support the substrate so that the substrate is suspended in the air, which facilitates the placement and removal of the substrate. When the substrate is actually processed, the carrier plate rises relative to the ejector pin to use the carrier plate to support the substrate.

[0023] When the ejector pins support the substrate, the inner bottom surface of the adjusting sleeve supports the ejector pins, and the height of the ejector pins can be changed by changing the height of the adjusting sleeve, so that the heights of all the ejector pins can be adjusted to be consistent and the substrate can be supported flatly; or by fine-tuning the height of the ejector pins, when the substrate is supported by multiple ejector pins, the two ends are slightly higher and the middle is slightly lower.

[0024] During the lifting process of the carrier plate, due to the arrangement of the guide sleeve, the carrier plate rises and falls along the ejector pin. When the ejector pin is deflected or the coaxiality between the ejector pin and the guide sleeve is insufficient, the ejector pin can partially move laterally relative to the guide sleeve due to the reserved gap between the ejector pin and the inner wall of the guide sleeve, and the bottom of the ejector pin is in an active state. The ejector pin can also tilt and rotate. Therefore, when the carrier plate is lifted or lowered, the ejector pin can adaptively move laterally or deflect to avoid the ejector pin being stuck on the carrier plate. The lifting and lowering movement of the carrier plate is smoother, ensuring that the shape of the ejector pin does not change, improving the support stability, and extending the support life of the ejector pin.

[0025] In a second aspect, a support assembly is provided, comprising:

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The embodiment of the present application provides a single-point support structure, support assembly and processing equipment, which supports the ejector pin by adjusting the sleeve, and leaves a gap between the ejector pin and the inner wall of the guide sleeve to support the ejector pin to move horizontally or deflect, and prevent the ejector pin from getting stuck on the bearing plate. The lifting and lowering movement of the bearing plate is smoother, ensuring that the shape of the ejector pin does not change, improving the support stability and extending the support life of the ejector pin. The present application solves the technical problem in the related art that the ejector pin and the bearing plate are easily stuck, affecting the lifting and lowering of the bearing plate, and easily damaging the ejector pin, resulting in poor support effect of the ejector pin and short support life.

[0043] Reference Figure 1 and Figure 2 A single-point support structure is used to be installed on a base plate 7 and a load-bearing plate 6 . The load-bearing plate 6 is located above the base plate 7 . The load-bearing plate 6 is set to be lifted and lowered, and the load-bearing plate 6 moves up and down above the base plate 7 .

[0044] Reference Figure 2-Figure 5 , wherein the single-point support structure A comprises an ejector pin 1, a guide sleeve 2 and an adjustment sleeve 3. The ejector pin 1 is inserted through a carrier plate 6, and a plurality of through holes for the ejector pin 1 to pass through are provided on the carrier plate 6, and the aperture of the through hole is larger than the diameter of the ejector pin 1. The ejector pin 1 passes through the carrier plate 6. Generally, a plurality of single-point support structures A are used to support the substrate at the same time.

[0045] When the substrate is taken or placed, the top surface of the carrier plate 6 is lower than the top of the ejector pins 1 , and the substrate is supported by a plurality of ejector pins 1 so that the substrate is suspended in the air, so as to facilitate the taking or placing of the carrier plate 6 .

[0046] When processing the substrate, the carrier plate 6 rises until the top surface of the carrier plate 6 is higher than the top of the ejector pin 1 , and the carrier plate 6 supports the substrate.

[0047] Reference Figure 2-Figure 5 The adjusting sleeve 3 is passed through the bottom plate 7, and the adjusting sleeve 3 includes a supporting inner bottom surface 3a. The bottom end of the ejector pin 1 is passed through the adjusting sleeve 3, and the bottom end of the ejector pin 1 abuts against the supporting inner bottom surface 3a, so that the ejector pin 1 is supported by the supporting inner bottom surface 3a.

[0048] In this configuration, the adjusting sleeve 3 supports the ejector pin 1 , and there is no need to fix the ejector pin 1 to the adjusting sleeve 3 , which facilitates the installation of the ejector pin 1 .

[0049] Reference Figure 2-Figure 5Furthermore, the adjusting sleeve 3 is lifted and lowered on the bottom plate 7, and the adjusting sleeve 3 can change its height relative to the bottom plate 7, so as to adjust the support height of the ejector pin 1, thereby adjusting the height of the top of the ejector pin 1. When multiple ejector pins 1 are used to support the substrate, the height of the ejector pin 1 can be changed by changing the height of the adjusting sleeve 3, so that the height of all ejector pins 1 can be adjusted to be consistent, and the substrate can be supported flatly. Alternatively, by fine-tuning the height of the ejector pin 1, when the substrate is supported by multiple ejector pins 1, the two ends are slightly higher and the middle is slightly lower. In this way, a variety of support requirements can be met.

[0050] The guide sleeve 2 is mounted on the bearing plate 6. In this embodiment, the guide sleeve 2 is partially sleeved in the through hole on the bearing plate 6, and the guide sleeve 2 is connected to the bearing plate 6 by bolts. The ejector pin 1 passes through the guide sleeve 2. In this embodiment, the guide sleeve 2 includes a linear bearing.

[0051] In this arrangement, the guide sleeve 2 is used to make the ejector pin 1 slidably connected to the carrier plate 6. On the one hand, the guide sleeve 2 is used to limit the deflection of the ejector pin 1, and combined with the support of the inner bottom surface 3a of the support to the ejector pin 1, the ejector pin 1 is stably installed. On the other hand, when the carrier plate 6 moves up and down, the carrier plate 6 slides with the ejector pin 1 through the guide sleeve 2, and the lifting process of the carrier plate 6 is smoother.

[0052] Furthermore, a gap is left between the circumferential outer side surface of the ejector pin 1 and the circumferential inner side surface of the guide sleeve 2. That is, the inner diameter of the guide sleeve 2 is larger than the diameter of the ejector pin 1.

[0053] With such arrangement, during the ascending process of the carrier plate 6, due to the arrangement of the guide sleeve 2, the carrier plate 6 ascends and descends along the ejector pin 1. When the ejector pin 1 is deflected or the coaxiality between the ejector pin 1 and the guide sleeve 2 is insufficient, due to the reserved gap between the ejector pin 1 and the inner wall of the guide sleeve 2 and the bottom of the ejector pin 1 being in an active state, the ejector pin 1 can partially shift laterally relative to the guide sleeve 2, and the ejector pin 1 can tilt and rotate. Therefore, when the carrier plate 6 is ascending and descending, the ejector pin 1 can adaptively shift or deflect laterally to avoid the ejector pin 1 being stuck on the carrier plate 6, and the ascending and descending movement of the carrier plate 6 is smoother, ensuring that the shape of the ejector pin 1 does not change, improving the support stability, and extending the support life of the ejector pin 1.

[0054] Preferably, the gap between the circumferential outer side surface of the ejector pin 1 and the circumferential inner side surface of the guide sleeve 2 is 0.01 mm-0.1 mm, so as to ensure the position limitation of the ejector pin 1 and support the ejector pin 1 to deflect or move laterally.

[0055] It should be noted that, since the ejector pin 1 is excessively deflected due to excessive lateral force applied thereto, there is a possibility that the guide sleeve 2 and the ejector pin 1 may become stuck.

[0056] Reference Figure 2-Figure 5, wherein the single-point support structure further includes a limiter 4, which is connected to the ejector pin 1 and arranged near the bottom end of the ejector pin 1, and is located in the adjustment sleeve 3. The adjustment sleeve 3 includes a limit inner top surface 3b, and a gap is left between the limiter 4 and the limit inner top surface 3b. The limiter 4 is restricted in the adjustment sleeve 3, and the ejector pin 1 is separated from the adjustment sleeve 3 from above by restricting the limiter 4 from separating from the adjustment sleeve 3.

[0057] When the ejector pin 1 is clamped with the guide sleeve 2, the carrier plate 6 rises, which drives the ejector pin 1 to rise. As the stopper 4 and the ejector pin 1 rise, the stopper 4 is adapted to approach and abut against the inner limit top surface 3b. When the inner limit top surface 3b exerts a downward force on the stopper 4, the clamping state between the ejector pin 1 and the guide sleeve 2 is released, thereby preventing the ejector pin 1 from rising together with the carrier.

[0058] In this way, by setting the limit member 4, the clamping state between the guide sleeve 2 and the ejector pin 1 can be automatically released as the carrying plate 6 rises. After the ejector pin 1 is released from the clamping state, the ejector pin 1 deflects to a vertical position. At this time, the sliding connection between the ejector pin 1 and the guide sleeve 2 is restored. After the ejector pin 1 is deflected, the movement of the guide sleeve 2 no longer interferes with the position of the ejector pin 1, and the ejector pin 1 will not be damaged.

[0059] Reference Figure 2-Figure 5 Specifically, the limiting member 4 includes a limiting piece 41 and a limiting nut 42. The circumferential side of the ejector pin 1 is provided with a step surface, the limiting piece 41 is sleeved on the ejector pin 1, and the top surface of the limiting piece 41 is pressed against the step surface, so that the limiting piece 41 is positioned and installed by using the step surface. The limiting nut 42 is threadedly connected to the ejector pin 1, and the limiting piece 41 is clamped between the step surface and the limiting nut 42, so that the fixing of the limiting piece 41 can be completed.

[0060] The diameter of the through hole for the ejector 1 to pass through, which is opened on the limiting inner top surface 3b of the adjusting sleeve 3, is smaller than the maximum length of the limiting plate 41, ensuring that when the ejector 1 rises, the limiting inner top surface 3b limits the rising movement of the limiting plate 41.

[0061] The bottom end of the ejector pin 1 is arranged in a ball head shape so that the ejector pin 1 is in point contact with the inner bottom surface 3a of the support.

[0062] In this arrangement, since the bottom end of the ejector pin 1 is arranged in a ball head, when the ejector pin 1 is deflected, the bottom end of the ejector pin 1 rolls to maintain the point contact between the ejector pin 1 and the inner bottom surface 3a of the support. It is easier to support the ejector pin 1 to deflect, and the ejector pin 1 deflects more smoothly and is not easy to get stuck, so that the shape of the ejector pin 1 is maintained.

[0063] Reference Figure 2-Figure 5 In this embodiment, the adjusting sleeve 3 is threadedly connected to the bottom plate 7, and the height of the adjusting sleeve 3 relative to the bottom plate 7 is changed by rotating the adjusting sleeve 3 relative to the bottom plate 7.

[0064] In this way, the height of the adjusting sleeve 3 can be adjusted by rotating, so that the height adjustment of the ejector pin 1 is more flexible and more accurate. Generally, the adjusting sleeve 3 is connected to the bottom plate 7 by a self-locking thread to prevent the adjusting sleeve 3 from sliding down due to force.

[0065] In other embodiments, the adjustment sleeve 3 can also be lifted and lowered by a connecting mechanism, a screw mechanism or by adding a gasket.

[0066] Reference Figure 2-Figure 5 In this embodiment, the adjusting sleeve 3 includes a sleeve body 31 and a cover body 32. The sleeve body 31 is inserted into the bottom plate 7, and a through hole for the ejector pin 1 to be inserted is provided at the top of the sleeve body 31, and the bottom surface of the sleeve body 31 is open. The sleeve body 31 is threadedly connected to the bottom plate 7, so that the height of the adjusting sleeve 3 can be changed by rotating the sleeve body 31.

[0067] In this configuration, due to the opening arrangement at the bottom of the sleeve body 31 , it is convenient to pass the ejector pin 1 through the sleeve body 31 from bottom to top, and the stopper 4 is placed inside the sleeve body 31 , which facilitates the assembly of the ejector pin 1 and the adjustment sleeve 3 .

[0068] The cover 32 is mounted on the bottom surface of the sleeve 31 to block the bottom end of the sleeve 31, and the top surface of the cover 32 is the supporting inner bottom surface 3a. In this embodiment, the cover 32 is fixed to the sleeve 31 by bolts to block the bottom end of the sleeve 31. In this way, the top surface of the cover 32 can form the supporting inner bottom surface 3a of the adjustment sleeve 3, and the cover 32 is used to support the ejector pin 1.

[0069] Reference Figure 2-Figure 5 Furthermore, an operating slot 32a is arranged on the bottom surface of the cover body 32. The operating slot 32a includes a hexagonal slot, a cross slot, a slot or a plum blossom slot. It is convenient to use a corresponding screwdriver to operate the cover body 32 and the sleeve body 31 to rotate, so as to change the height of the adjustment sleeve 3 relative to the bottom plate 7.

[0070] Optionally, the single-point support structure further includes a support head 5 , which is sleeved on the top end of the ejector pin 1 .

[0071] Specifically, the support head 5 is threadedly connected to the top end of the ejector pin 1. The support head 5 is made of rubber or plastic.

[0072] In this arrangement, the support head 5 replaces the ejector pin 1 to contact the substrate, and the ejector pin 1 is made of metal to ensure its strength. The hardness of the support head 5 is less than that of the ejector pin 1 to reduce the possibility of scratching the substrate, and the support head 5 is replaceable to protect the ejector pin 1 and increase the service life of the ejector pin 1.

[0073] The embodiment of the present application provides a single-point support structure. Generally, multiple single-point support structures are used to support the substrate so that the substrate is suspended in the air, which facilitates the placement and removal of the substrate. When the substrate is actually processed, the carrier plate 6 rises relative to the ejector pin 1 to use the carrier plate 6 to support the substrate.

[0074] When the ejector pin 1 supports the substrate, the supporting inner bottom surface 3a of the adjusting sleeve 3 supports the ejector pin 1, and the height of the ejector pin 1 can be changed by changing the height of the adjusting sleeve 3, so that the height of all the ejector pins 1 can be adjusted to be consistent to support the substrate flatly; or by fine-tuning the height of the ejector pin 1, when the substrate is supported by multiple ejector pins 1, the two ends are slightly higher and the middle is slightly lower.

[0075] During the ascending process of the carrier plate 6, due to the arrangement of the guide sleeve 2, the carrier plate 6 rises and falls along the ejector pin 1. When the ejector pin 1 is deflected, or the coaxiality between the ejector pin 1 and the guide sleeve 2 is insufficient, due to the reserved gap between the ejector pin 1 and the inner wall of the guide sleeve 2, and the bottom of the ejector pin 1 is in an active state, the ejector pin 1 can be partially displaced laterally relative to the guide sleeve 2, and the ejector pin 1 can be tilted and rotated. Therefore, when the carrier plate 6 is raised and lowered, the ejector pin 1 can be adaptively displaced or deflected laterally to avoid the ejector pin 1 being stuck on the carrier plate 6. The lifting and lowering movement of the carrier plate 6 is smoother, ensuring that the shape of the ejector pin 1 does not change, improving the support stability, and extending the support life of the ejector pin 1.

[0076] Reference Figure 6 Another embodiment of the present application provides a support assembly, including: a base plate 7, a bearing plate 6, a lifting drive member and a plurality of single-point support structures A as described above.

[0077] The adjustment sleeves 3 of the multiple single-point support structures A are all installed on the bottom plate 7 .

[0078] The bearing plate 6 is located above the bottom plate 7, the guide sleeves 2 of the multiple single-point support structures A are all installed on the bearing plate 6, and the ejector pins 1 of the single-point support structure A are penetrated through the bearing plate 6. The lifting drive is connected to the bearing plate 6 to drive the bearing plate 6 to rise and fall. The lifting drive includes a screw mechanism, a linear motor or a cylinder.

[0079] Among them, a plurality of single-point support structures A support the non-display area of ​​the substrate to avoid damaging the display area.
