TECHNICAL FIELD
[0001] The present application relates to the field of bearing assembly rotation conversion mechanism, processing equipment and printing system. BACKGROUND
[0002] In the manufacturing process of the existing OLED device or QLED device, an inkjet printing process has been adopted. Some functional materials can be printed by using the inkjet printing process, for example, the hole injection layer (HIL), the hole transport layer (HTL), the light-emitting layer material (EML), and other functional materials can be printed by using the inkjet printing process, and other functional layers that can be printed by using the inkjet printing process are also applicable. That is, the functional layer material ink is printed on the substrate by using the inkjet printing process.
[0003] For various factors affecting the efficiency of the OLED device, the film uniformity of each functional layer material is an important point for investigation. After printing, the substrate needs to be dried and baked through various auxiliary equipment to form a film.
[0004] In the related art, during the processing, the substrate is located in the processing chamber and is supported by the bearing assembly. The bearing assembly includes a bearing plate and a plurality of pins connected to the bearing plate. The distribution form of the pins is determined according to the position of the non-display area on the substrate. Generally, referring to Figure 1 , the plurality of pins 9 are distributed at the edge position of the substrate A, and the plurality of pins 9 form a rectangular shape to avoid supporting the substrate A in the display area and to avoid affecting the display area.
[0005] Since the distribution position of the plurality of pins and the relative position of the processing chamber are determined, the substrate can only enter the processing chamber from a specific direction to ensure that the non-display area on the substrate falls on the pins. However, different processing equipment is not located in the same direction, and the placement direction of the substrate may be different in different processes. Therefore, after the substrate is processed in the previous process, the placement form of the substrate may not match the distribution form of the pins in the processing chamber of the next processing process, that is, some pins support the display area of the substrate. Therefore, before the substrate enters the processing chamber, the substrate is rotated to adapt to the position of the pins in the next processing process. In this way, not only is it necessary to additionally arrange a mechanism for rotating the substrate, but also the processing cycle of the substrate is affected, which adversely affects the processing efficiency of the substrate.

DETAILED DESCRIPTION
[0044] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0045] The embodiments of the present application provide a rotating and reversing mechanism of a bearing assembly, a processing device and a printing system. The bearing plate is carried by the sliding plate to a reversing station, and the bearing plate is pushed by the reversing assembly and driven to rotate, and then the sliding plate is used to send the rotated bearing plate back to the processing chamber, so as to ensure that the pins on the bearing plate support the non-display area of the substrate. By changing the placing direction of the bearing plate, the feeding requirements of the substrate in different directions can be met, and the reversing structure does not need to be additionally arranged on the substrate transfer structure, so that the substrate transfer structure is simplified, the substrate does not need to be rotated during feeding, the processing cycle of the substrate is optimized, and the processing efficiency is improved. The present application solves the technical problem that the substrate in the related art does not match the position of the pins in the next process, and the substrate needs to be rotated and then sent into the processing chamber, which complicates the substrate transfer structure and has a bad influence on the processing cycle of the substrate.
[0046] Reference Figure 1 and Figure 2 A rotating and reversing mechanism of a bearing assembly is used to reverse the bearing assembly and adapt to the support of the substrate A in different placing directions. The bearing assembly includes a bearing plate 8 and a plurality of pins 9. The plurality of pins 9 are connected to the bearing plate 8, and the plurality of pins 9 are used to support the non-display area of the substrate A. The position of the plurality of pins 9 is changed by rotating the bearing plate 8, so as to adapt to the support of the substrate A in different placing directions sent to the processing chamber.
[0047] ReferenceFigure 2 and Figure 3 The rotating and reversing mechanism of the bearing assembly comprises a frame body 1, a sliding plate 2 and a reversing assembly 3 installed on the frame body 1. The sliding plate 2 is slidingly arranged on the frame body 1, and the sliding plate 2 is used for supporting a bearing plate 8 which moves together with the sliding plate 2. When it is needed to change the distribution position of the pins 9 on the bearing plate 8, the sliding plate 2 is slid out of the processing chamber to the frame body 1, the bearing plate 8 is moved to a reversing station, and the bearing plate 8 is rotated by the reversing assembly 3 to adjust the positions of the pins 9 on the bearing plate 8. The bearing plate 8 after the adjustment is sent to the processing chamber by the sliding plate 2, which is adapted to the placing direction of the substrate A after the substrate A is sent to the processing chamber, so as to ensure that the pins 9 on the bearing plate 8 support the non-display area of the substrate A. By only changing the placing direction of the bearing plate 8, the feeding requirements of the substrate A in different directions can be met, and a reversing structure does not need to be additionally arranged on the transfer structure of the substrate A, so that the transfer structure of the substrate A is simplified, the substrate A does not need to be rotated during feeding, the processing cycle of the substrate A is optimized, and the processing efficiency is improved.
[0048] It should be noted that during the processing of the substrates A in the same batch, each substrate A, the placing direction, the feeding direction and the transfer direction are consistent. Therefore, before processing, the positions of the pins 9 in the processing chamber are adaptively adjusted according to the placing direction, the feeding direction and the transfer direction of the substrate A, so as to adapt to the support of the substrate A.
[0049] The rotating and reversing mechanism of the bearing assembly further comprises a limiting structure 4 for limiting the movement of the bearing plate 8 relative to the sliding plate 2. When the sliding plate 2 moves, the bearing plate 8 does not relatively displace with the sliding plate 2 under the action of the limiting structure 4.
[0050] In this way, on the one hand, the bearing plate 8 is prevented from falling off the sliding plate 2, and on the other hand, the relative position of the sliding plate 2 and the bearing plate 8 is not easy to change, that is, the position of the bearing plate 8 can be determined by the position of the sliding plate 2, so that the bearing plate 8 can be more accurately placed in the reversing station, the reversing of the bearing plate 8 by the reversing assembly 3 is ensured, and after the bearing plate 8 enters the processing chamber together with the sliding plate 2, the position of the bearing plate 8 in the processing chamber is more controllable, so that the bearing plate 8 can be conveniently sent to a specified position in the processing chamber, and the processing quality of the substrate A is ensured.
[0051] In this embodiment, the reversing assembly 3 is used to lift the bearing plate 8 off the sliding plate 2 and then rotate the bearing plate 8. Finally, the bearing plate 8 after the adjustment is lowered to be supported by the sliding plate 2.
[0052] Referring to Figure 3Specifically, the limiting structure 4 comprises at least one limiting pin 41 and a plurality of limiting holes 42. One of the limiting pin 41 and the limiting hole 42 is arranged on the sliding plate 2, and the other is arranged on the bearing plate 8. The limiting pin 41 and the limiting hole 42 are inserted and matched to make the sliding plate 2 and the bearing plate 8 inserted and matched in the vertical direction, and limit the movement of the bearing plate 8 relative to the sliding plate 2 in the horizontal direction. In the embodiment, the limiting pin 41 is fixed to the top surface of the sliding plate 2, and the limiting hole 42 is formed in the bottom surface of the bearing plate 8. In other embodiments, the limiting hole 42 is arranged on the sliding plate 2, and the limiting pin 41 is arranged on the bearing plate 8.
[0053] Further, the plurality of limiting holes 42 are uniformly circumferentially distributed about the center line of the bearing plate 8. After the bearing plate 8 rotates by a certain angle, the limiting pin 41 corresponds to another limiting hole 42, and as the bearing plate 8 descends, the bearing plate 8 is re-inserted and matched with the sliding plate 2. In the embodiment, the limiting pin 41 can comprise a plurality of limiting pins 41, which are uniformly circumferentially distributed about the rotation axis of the bearing plate 8, and each of the plurality of limiting pins 41 has a corresponding limiting hole 42.
[0054] In this way, the limiting pin 41 and the limiting hole 42 limit the horizontal movement of the bearing plate 8 relative to the sliding plate 2, and ensure that the bearing plate 8 can be accurately moved to a specified position with the sliding plate 2, and ensure that the reversing assembly 3 acts on the bearing plate 8 at the reversing station to ensure the reversing of the bearing plate 8. In addition, by jacking up the bearing plate 8, the limiting of the bearing plate 8 on the sliding plate 2 can be released, so as to facilitate the rotation of the bearing plate 8. The bearing plate 8 is unlocked by jacking up and locked by descending, which is simple to operate and facilitates the limiting and unlocking of the bearing plate 8.
[0055] In other embodiments, the limiting structure 4 can further comprise a magnet, and at least one of the sliding plate 2 and the bearing plate 8 is arranged with the magnet, so that the sliding plate 2 and the bearing plate 8 are magnetically attracted to limit the relative movement of the bearing plate 8 and the sliding plate 2. After the bearing plate 8 is jacked up, the bearing plate 8 is disconnected from the magnetic connection with the sliding plate 2, thereby supporting the rotation of the bearing plate 8. Preferably, the limiting structure 4 can comprise an electromagnet.
[0056] Referring to Figures 4-6 Optionally, the rotating and reversing mechanism of the bearing assembly further comprises a sliding assembly 6, and the sliding plate 2 slides on the frame 1 through the sliding assembly 6. The sliding assembly 6 comprises a plurality of sliding rails 61 and a plurality of rollers 62.
[0057] The sliding rail 61 is connected to the frame 1, and a plurality of sliding rails 61 are arranged in parallel and at intervals. The plurality of rollers 62 are installed on the sliding plate 2, and the plurality of rollers 62 are divided into a plurality of groups, and the plurality of groups of rollers 62 roll on the plurality of sliding rails 61, respectively.
[0058] In this way, by sliding the rollers 62 on the slide rails 61, on one hand, the sliding plate 2 is more smoothly moved, and the carrying plate 8 is conveniently moved to a position; on the other hand, the rollers 62 and the slide rails 61 are matched to limit the sliding direction of the sliding plate 2, and the direction accuracy of the sliding plate 2 is improved.
[0059] With reference to Figures 4-6 Further, the slide rails 61 are at least two. The axis of the rollers 62 is vertical, the circumferential side of the rollers 62 is provided with clamping ring grooves, and the two groups of rollers 62 are respectively rolled on the opposite sides of the two slide rails 61, and the rollers 62 are clamped with the slide rails 61 through the clamping ring grooves. Therefore, the two groups of rollers 62 clamp the two slide rails 61, and the groove walls of the clamping ring grooves support the rollers 62, the sliding plate 2 and the carrying plate 8.
[0060] In this way, since the rotating axis of the rollers 62 is vertically installed, the vertical space occupied by the rollers 62 is reduced, and the processing chamber with a small opening can be conveniently matched. Even if the opening of the processing chamber is small, the sliding plate 2 and the carrying plate 8 can still be supported to slide out of the processing chamber.
[0061] Optionally, the rotating switching mechanism of the carrying assembly further comprises a locking assembly 7, which is used to limit the movement of the sliding plate 2 at the switching position relative to the slide rails 61.
[0062] In this way, at the switching position, the movement of the sliding plate 2 is limited by the locking assembly 7, and when the switching assembly 3 acts on the carrying plate 8, the sliding plate 2 is not easy to deviate from the position, so as to ensure that the lifting and rotation of the carrying plate 8 are smoothly carried out.
[0063] With reference to Figure 7 Specifically, the locking assembly 7 comprises a clamping head 71 and a matching block 72. The clamping head 71 is connected to the sliding plate 2, and the matching block 72 is fixed on the frame 1. The matching block 72 is provided with a clamping groove, and the opening of the clamping groove is arranged to face the clamping head 71. As the sliding plate 2 slides to the switching position, the clamping head 71 gradually approaches the matching block 72, and finally the clamping head 71 is inserted into the clamping groove. The clamping head 71 is adapted to be inserted into the clamping groove, and the clamping head 71 is clamped by the groove wall of the clamping groove, so as to limit the clamping head 71 from being separated from the clamping groove.
[0064] In this way, when the sliding plate 2 slides to the switching position, the clamping head 71 is inserted into the clamping groove, and the clamping head 71 is clamped by the clamping groove of the matching block 72, so as to limit the sliding of the sliding plate 2 on the slide rails 61. When it is necessary to release the sliding locking state of the sliding plate 2, the sliding plate 2 is pushed by applying force to the sliding plate 2, so as to pull out the clamping head 71 from the clamping groove, so as to unlock the sliding of the sliding plate 2.
[0065] Preferably, the locking assembly 7 is provided with multiple groups, so as to improve the locking stability.
[0066] With reference toFigure 5 and Figure 8 Wherein, the reversing assembly 3 comprises a jacking driving member 31 and a turning assembly 32. The jacking driving member 31 is installed on the frame body 1, and the fixed end of the turning assembly 32 is installed on the jacking end of the jacking driving member 31. The turning assembly 32 is driven to rise by the jacking driving member 31. A through slot is formed on the sliding plate 2 for the turning assembly 32 to pass through. The turning assembly 32 is driven to rise by the jacking driving member 31 so that the rotating end of the turning assembly 32 passes through the sliding plate 2 to jack up the bearing plate 8. The bearing plate 8 rotates together with the rotating end of the turning assembly 32.
[0067] In this way, the turning assembly 32 is driven to rise by the jacking driving member 31 to pass through the sliding plate 2. The rotating end of the turning assembly 32 supports the bearing plate 8 and jacks up the bearing plate 8, so that the bearing plate 8 is separated from the sliding plate 2. Then, the bearing plate 8 rotates together with the rotating end of the turning assembly 32, so as to realize the reversing of the bearing plate 8 and change the distribution of the positions of the pins 9 on the bearing plate 8.
[0068] In this way, at the reversing station, the jacking driving member 31 drives the turning assembly 32 to rise to push the bearing plate 8, so that the bearing plate 8 is separated from the sliding plate 2. The bearing plate 8 is driven to rotate by the turning assembly 32, so as to change the distribution of the pins 9 on the bearing plate 8. After the bearing plate 8 is reversed, the distribution of the pins 9 on the bearing plate 8 is adapted to the placement form of the substrate A. Finally, the sliding plate 2 is moved to send the sliding plate 2 and the bearing plate 8 into the processing chamber, so as to complete the position adjustment of the pins 9.
[0069] By rotating the bearing plate 8 and then sending it into the processing chamber, the placement direction of the bearing plate 8 is adapted to the placement direction of the substrate A after the substrate A is sent into the processing chamber, so as to ensure that the pins 9 on the bearing plate 8 support the non-display area of the substrate A. By only changing the placement direction of the bearing plate 8, the feeding requirements of the substrate A in different directions can be met. The reversing structure does not need to be additionally arranged on the substrate A conveying structure, so as to simplify the substrate A conveying structure. The substrate A does not need to be rotated during feeding, so as to optimize the processing cycle of the substrate A and improve the processing efficiency.
[0070] Wherein, the jacking driving member 31 comprises a pneumatic cylinder, a linear motor or a screw mechanism.
[0071] Referring to Figure 8 Wherein, the turning assembly 32 comprises a mounting seat 321 and a rotating disc 322. The mounting seat 321 is installed on the jacking end of the jacking driving member 31. The rotating disc 322 is rotatably connected to the mounting seat 321, and the rotating disc 322 is driven to rise to support and jack up the bearing plate 8. In this embodiment, the rotating disc 322 is rotatably connected to the mounting seat 321 through a bearing.
[0072] In this way, after the lifting of the bearing plate 8, the bearing plate 8 can be rotated together with the rotating disc 322 to adjust the position, and the bearing plate 8 can be easily rotated by manual operation.
[0073] In other embodiments, the steering assembly 32 further comprises a steering driving member integrated in the rotating seat and drivingly connected with the rotating disc 322 to drive the rotating disc 322 to rotate by the steering driving member. The steering driving member comprises a rotary air cylinder or a motor.
[0074] Further, the surface of the rotating disc 322 is fixed with a rubber pad to increase the friction between the rotating disc 322 and the bearing plate 8, reduce the possibility of relative movement between the rotating disc 322 and the bearing plate 8, and avoid the rotating disc 322 from hitting the bearing plate 8.
[0075] Referring to Figure 8 Optionally, the steering assembly 32 further comprises an angle positioning assembly 323, which is used to ensure that the bearing plate 8 is rotated to adjust a specified angle, and improve the adjustment accuracy of the bearing plate 8. The rotating angle of the bearing plate 8 includes 90 degrees, 45 degrees or 30 degrees.
[0076] Referring to Figure 8 The angle positioning assembly 323 comprises a positioning rod 3232 and two positioning seats 3231. The positioning seats 3231 are installed on the mounting seat 321, the distance between the two positioning seats 3231 and the rotating axis of the rotating disc 322 is consistent, and the included angle between the two positioning seats 3231 and the rotating axis of the rotating disc 322 is a specified angle. The specified angle includes 90 degrees, 45 degrees or 30 degrees. The positioning rod 3232 is fixed with the rotating disc 322, and the positioning rod 3232 is adapted to rotate with the rotating disc 322 and abut against the positioning seats 3231. The positioning rod 3232 rotates between the two positioning seats 3231, and the rotating angle of the rotating disc 322 is determined by the abutment between the positioning rod 3232 and the positioning seats 3231, so as to position the rotating angle of the bearing plate 8.
[0077] In this way, by the cooperation of the positioning rod 3232 and the positioning seats 3231, the positioning rod 3232 abuts against one of the positioning seats 3231, and then abuts against the other positioning seat 3231, so as to limit the rotating angle of the rotating disc 322, facilitate the rotating of the bearing plate 8 to the specified angle, and improve the adjustment efficiency of the bearing plate 8.
[0078] Further, by changing the position of the positioning seat 3231, the included angle formed between the two positioning seats 3231 is changed, so as to realize the positioning of multiple rotating angles.
[0079] Referring to Figure 9Optionally, the rotation conversion mechanism of the bearing assembly further comprises an abutting member 5 which is detachably connected to the frame 1. The abutting member 5 is used to abut against the side surface of the bearing plate 8 at the conversion station of the bearing plate 8, so as to limit the rotation of the adjusted bearing plate 8 when it is lowered, and ensure the position adjustment accuracy of the bearing plate 8.
[0080] With reference to Figure 9 Specifically, the abutting member 5 comprises a stop rod which is detachably connected to the frame 1 by insertion. When the bearing plate 8 rotates, the abutting member 5 is detached from the frame 1 so as not to interfere with the rotation of the bearing plate 8. After the rotation of the bearing plate 8, the abutting member 5 is connected to the frame 1, and abuts against the side surface of the bearing plate 8 so as to limit the rotation of the bearing plate 8.
[0081] In this way, after the rotation of the bearing plate 8 is completed, the abutting member 5 abuts against the opposite side surfaces of the bearing plate 8 respectively, so as to limit the arbitrary rotation of the bearing plate 8, and ensure the re-insertion of the bearing plate 8 and the sliding plate 2 during the lowering process.
[0082] Preferably, two abutting members 5 are provided, and the two abutting members 5 are respectively used to abut against the opposite side surfaces of the bearing plate 8, so as to sufficiently limit the rotation of the bearing plate 8.
[0083] The rotation conversion mechanism of the bearing assembly provided by the embodiment of the present application is arranged at the opening of the processing cavity when the placement form of the substrate A does not match the distribution form of the pins 9 in the processing cavity of the next processing procedure, the sliding plate 2 is used to carry the bearing plate 8 and the pins 9 out of the processing cavity, and the bearing plate 8 is brought to the conversion station by the sliding of the sliding plate 2. At the conversion station, the lifting driving member 31 drives the rotation component 32 to rise to push the bearing plate 8, so that the bearing plate 8 is separated from the sliding plate 2, and the rotation component 32 is used to rotate the bearing plate 8, so that the distribution positions of the plurality of pins 9 on the bearing plate 8 are changed, and the distribution form of the pins 9 on the bearing plate 8 after the rotation is adapted to the placement form of the substrate A. Finally, the sliding plate 2 is moved, and the sliding plate 2 and the bearing plate 8 are sent into the processing cavity, so that the position adjustment of the pins 9 is completed.
[0084] By rotating the bearing plate 8 and then sending it into the processing cavity, the placement direction of the substrate A after it is sent into the processing cavity is adapted, so that the pins 9 on the bearing plate 8 support the non-display area of the substrate A.
