For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

Referring to fig. 1 and 2, fig. 1 illustrates a structure of a printing plate of a conventional nanoimprinting technique, and fig. 2 illustrates a process of the nanoimprinting technique, specifically, imprinting a pattern on the printing plate on an imprinting glue on a substrate. The existing nanoimprint technology is a pattern transfer technology, uses mechanical means to transfer patterns, has the advantages of high resolution, easy mass production, low cost and simple process, is an important manufacturing technology of nano-sized electronic devices, and has wide application in the fields of silicon field effect transistors, nano electromechanical systems, microwave integrated circuits, nano electronic devices, nano integrated circuits, quantum memory devices, photonic crystal arrays, OLED flat panel display arrays and the like. The basic principle of the nano-imprinting technology is to manufacture a template with a microstructure pattern, then imprint the pattern on the template on a material to be processed, solidify the pattern, and finally remove the template to finish the pattern transfer. Although high imprinting precision can be realized by using the traditional imprinting technology, large-area preparation of a micro-nano structure cannot be realized, so that large-area imprinting cannot be carried out.

The basic principle of screen printing is that during printing, ink is coated on a printing plate, printing stock is placed under the printing plate, and the ink is transferred to the printing stock through a through hole by pressure (such as ink scraping) through a through hole. However, the screen printing has low precision, and the resolution is generally tens of microns, so the screen printing cannot carry out stamping with submicron precision, and the precision is low.

In order to solve the problems, the imprinting equipment provided by the embodiment of the application combines the advantages of high imprinting precision and large screen printing area of the nano-imprinting technology, the imprinting process is visible by naked eyes, a vacuum condition is not needed, the operation is easy, the cost is much lower than that of the traditional nano-imprinting technology, the large-area imprinting at the submicron level is realized, and the imprinting efficiency and the convenience are improved.

Referring to fig. 3 to 7, fig. 3 is a schematic structural diagram of an imprint apparatus 100 according to an embodiment of the present disclosure. This impression equipment 100 can be submicron impression equipment, can solve the nanometer impression technique in the impression area less, the problem that efficiency is lower, has realized the large tracts of land impression of submicron level precision, has improved user experience.

As shown in fig. 3 to 6, the imprint apparatus 100 includes: a screen printer body 10, a screen printing based uv curing imprint platform 20, an imprint head 30, a frame 40, and a printing plate 50. Wherein, a screen printing based ultraviolet curing imprinting platform 20 is arranged on the screen printer body 10, and the screen printing based ultraviolet curing imprinting platform 20 is used for bearing the substrate to be imprinted. The imprint head 30 is disposed on the screen printer body 10, the frame 40 is disposed on the screen printer body 10 and above the screen printing-based ultraviolet curing imprint platform 20, and the printing plate 50 is disposed on the frame 40.

Specifically, the screen printing based uv-curing imprinting platform 20, the imprinting head 30 and the frame 40 are detachably connected to the screen printer body 10, and the frame 40 is located above the screen printing based uv-curing imprinting platform 20 and below the imprinting head 30, so that the imprinting head 30 applies pressure to the printing plate 50 disposed on the frame 40, wherein the printing plate 50 can be placed on the frame 40 and detachably connected to the frame 40.

In some embodiments, as shown in fig. 3, the screen printer body 10 includes a limiting member 11, and the screen frame 40 is detachably connected to the screen printer body 10 through the limiting member 11.

In some embodiments, as shown in fig. 4, in particular, the frame 40 includes a frame 41 and a bottom plate 42 disposed on the frame 41, wherein the bottom plate 42 is opened with printing plate holes 420, and the printing plate holes 420 are used for placing the submicron-sized patterns 51 of the printing plate 50.

In some embodiments, the area of plate holes 420 matches the area of sub-micron pattern 51 of plate 50.

In some embodiments, as shown in fig. 5, printing plate 50 includes a submicron pattern 51, wherein printing plate 50 is in positive fit with bottom plate 42 such that printing plate 50 is placed on frame 40 and submicron pattern 51 is matched with printing plate holes 420, such that during imprinting process, submicron pattern 51 can contact with the imprinting glue on the substrate through printing plate holes 420 to realize imprinting.

Specifically, as shown in fig. 6, the printing plate holes 420 are located in the middle of the frame 40, and the frame 40 is an elastic frame, so that the frame 40 can make the printing plate 50 rebound to the initial height according to its own elasticity after the printing is completed, thereby achieving the separation of the printing plate 50 from the printing paste. This imprinting process continues until the imprint head 30 moves from one end of the printing plate 50 to the other and performs imprinting, at which point the pattern 51 on the printing plate 50 is transferred in its entirety to the substrate of the screen-printing based uv-cured imprinting station 20.

It should be noted that the area of the plate holes 420 is not particularly limited, and the area of the plate holes 420 may be determined according to the area of the sub-micron pattern 51 on the printing plate 50, and generally, the area of the plate holes 420 is slightly smaller than the area of the frame 40, so that the printing plate 50 can be conveniently fixed on the frame 40.

Wherein, the distance between the screen frame 40 and the ultraviolet curing imprinting platform 20 based on screen printing is less than the maximum elastic distance of the screen frame 40, so that the screen frame 40 can make the printing plate 50 rebound to the initial position after the imprinting is completed, thereby realizing the separation of the printing plate 50 and the imprinting glue.

Referring to fig. 7, fig. 7 is a schematic view of an operating principle of an imprinting apparatus provided in an embodiment of the present application, when the apparatus operates in an ultraviolet curing mode, a substrate is placed on an ultraviolet curing imprinting platform 20 based on screen printing, and an imprinting adhesive is pre-coated on the substrate, where the imprinting adhesive is an ultraviolet curing adhesive, a control system of a screen printer body 10 controls a imprinting head 30 to apply pressure to a printing plate 50, so that the printing plate 50 is imprinted on the substrate on the ultraviolet curing imprinting platform 20 based on screen printing, so that a pattern of a contact portion between the imprinting head 30 and the printing plate 50 is imprinted on the ultraviolet curing adhesive on the substrate, the ultraviolet curing adhesive is subjected to ultraviolet curing, and the control system of the screen printer body 10 controls the imprinting head 30 to move to implement scraping printing, so as to imprint a submicron-sized pattern 51 on the printing plate 50 on the imprinting adhesive on the substrate, the specific working flow is shown in fig. 7, while in the thermal curing mode, only the curing means is different, but the stamping manner and the stamping flow are the same as in the ultraviolet curing mode.

In some embodiments, the screen printer body 10 is used to provide the required pressure for imprinting, and the control system of the screen printer body 10 may adjust imprinting parameters, such as imprinting pressure, imprinting speed, imprinting time, and the like, and perform scraping according to the adjusted imprinting parameters.

For example, since different printing pastes have different requirements for printing parameters, such as printing pressure, printing speed, printing time, and the like, the printing apparatus 100 obtains the printing parameters preset by the user before starting to operate, and the control system of the screen printer body 10 controls the printing apparatus 100 to operate according to the printing parameters.

In some embodiments, as shown in fig. 8, the imprint head 30 includes a contact portion 31, and the contact portion 31 is configured to contact the printing plate 50, wherein the contact portion is disposed at a predetermined inclination angle, so that the imprint head and the printing plate can achieve better contact, improve scraping effect, and improve imprinting efficiency. Specifically, the preset inclination angle may be 5 ° or 10 °, and is not particularly limited herein.

In some embodiments, contact 31 is a linear contact and imprint head 30 is in linear contact with printing plate 50. The linear contact portion is a contact portion of the print head 30 and the printing plate 50, wherein the contact portion of the print head 30 and the printing plate 50 is in linear contact.

Referring to fig. 9 and 10, in some embodiments, the uv curing imprinting stage 20 based on screen printing includes a curing stage 21, a carrier plate 22, a driving assembly 23, and a light emitting member 24; curing stage 21 includes slide rails 210; bearing plate 22 sets up on solidification platform 21, and bearing plate 22 includes the printing opacity piece, and bearing plate 22 is used for bearing the substrate of treating the impression, and the printing opacity piece is very high to the transmissivity of ultraviolet ray for the ultraviolet ray that sends 24 of illuminating part can shine on the ultraviolet curing glue on the substrate after passing through the printing opacity piece smoothly, and the impression that has impressed the pattern of submicron order on the substrate is glued and is solidified, wherein, the substrate sets up the top of printing opacity piece, and the ultraviolet ray that 24 of illuminating part sent promptly must see through the printing opacity piece and just can shine on the substrate.

The driving assembly 23 includes a driving motor 230, a driving member 231, and a sliding member 232, wherein the sliding member 232 is disposed on the slide rail 210, the driving motor 230 and the driving member 231 are mechanically coupled and drive the driving member 231 to move, and the driving member 231 moves and drive the sliding member 232 to slide along a first direction relative to the slide rail 210. The light emitting member 24 is used for emitting light, and the light emitting member 24 is disposed on the sliding member 232 and faces the loading plate 22.

It should be noted that the number of the sliding members 232 may be one, or may be multiple, and the number of the sliding members 232 is the same as that of the sliding rails 210. Most preferably, the sliding member 232 and the sliding rail 210 are two in number and are disposed at both ends of the light emitting member 24.

The driving motor 230 refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as power source of electric appliance or various machines. Therefore, any device that can provide a power source for the driving member 231 can be used as the driving motor 230 of the embodiment of the present application. The driving member 231 may be a screw or a drag chain, for example, a ball screw, and the driving motor 230 drives the ball screw to rotate, and the ball screw can convert the rotation motion into a linear motion to drive the sliding member 232 to slide along the first direction relative to the sliding rail 210. The first direction is a moving direction of the impression head 30 of the slide rail on a horizontal plane.

In the present embodiment, the imprint paste imprinted with the submicron pattern is cured by the ultraviolet curing method, so that the imprint head 30 in the present embodiment may only have an imprinting function without having a heating function, and then the imprint paste imprinted with the submicron pattern on the substrate is subjected to the ultraviolet curing by the ultraviolet curing imprint platform 20 based on the screen printing.

When the imprinting apparatus 100 works, the driving motor 230 drives the sliding member 232 to slide on the sliding rail 210 along the first direction, and drives the light emitting member 24 to move along with the sliding member 232 relative to the sliding rail 210, so that the light emitted by the light emitting member 24 irradiates the substrate through the light transmitting member, and the imprinting glue imprinted with the submicron-level pattern on the substrate is cured. Therefore, the driving motor 230 can drive the sliding part 232 to slide on the sliding rail 210, so that the synchronous work of the luminous part 24 and the stamping head 30 is realized, the stability of the movement process of the luminous part 24 is improved, the stamping effect and the space utilization rate are improved, and meanwhile, the material and the manufacturing cost are saved.

Note that, in the present embodiment, the imprint paste imprinted with the submicron-sized pattern is cured by ultraviolet curing, and therefore, the imprint paste should be ultraviolet curing paste.

Illustratively, when the imprint apparatus 100 is in operation, the sliding direction of the slider 232 on the slide rail 210 is the same as the moving direction of the imprint head 30 on the horizontal plane; wherein the sliding speed of the slider 232 on the slide rail 210 is the same as the moving speed of the print head 30. Therefore, the imprinting and the ultraviolet curing can be carried out synchronously, the imprinting step is simplified, and the imprinting efficiency is improved.

Specifically, the slider 232 and the imprint head 30 both move in the same direction and at the same rate, i.e., the light emitter 24 and the imprint head 30 can be kept relatively stationary during the imprinting process.

In some embodiments, as shown in fig. 11, the slide rail 210 includes a slide 211 and a slide wall 212, the slide 211 for sliding engagement with the slide 232; the sliding walls 212 are disposed on both sides of the sliding track 211 to form a limit fit of the sliding member 232 with the sliding rail 210 in the second direction.

Wherein the second direction is perpendicular to the first direction and the direction of movement of the imprint head 30 on the vertical plane. Therefore, the sliding piece 232 can only slide on the slide way 211 and is not easy to derail, and the slide way 211 can be protected by arranging the slide wall 212, so that the durability of the slide way 211 is improved.

Illustratively, one surface of the sliding member 232 facing the bearing plate 22 is provided with a limiting groove 233, the limiting groove 233 is used for placing the light emitting member 24, and one surface of the sliding member 232 facing away from the bearing plate 22 is used for contacting with the sliding rail 211 to realize sliding fit. Therefore, the surface of the sliding member 232 facing away from the carrier plate 22 can be made of a smoother material to reduce the friction of the sliding member 232 when the sliding track 211 slides. The sliding device such as a pulley can be further installed on the surface of the sliding member 232 away from the bearing plate 22, so that the friction force of the sliding member 232 when the sliding rail 211 slides is reduced, the sliding member 232 can accurately follow the movement of the imprint head 30 in the first direction, the synchronism of the light-emitting lamp tube and the imprint head is improved, and the ultraviolet curing efficiency is improved.

Illustratively, as shown in FIG. 11, the limiting groove 233 has a circular arc-shaped cross-section. Because the light emitting element 24 is generally a cylindrical object such as a lamp tube, the cross section of the limiting groove 233 can be set to be an arc shape, and if the number of the sliding elements 232 is one, the middle part of the light emitting element 24 can be attached to the limiting groove 233 and placed in the limiting groove 233; if the number of the sliding members 232 is two, two ends of the light emitting member 24 can be attached to the limiting grooves 233 and placed in the limiting grooves 233.

By providing the limiting groove 233 and setting the cross section of the limiting groove 233 to be a circular arc shape, it is possible to prevent the light emitting member 24 from being separated from the sliding member 232 due to the reciprocating movement of the sliding member 232 when the sliding member 232 moves.

In some embodiments, as shown in fig. 11, the sliding member 232 further includes a limiting protrusion 234, and the limiting protrusion 234 is configured to cooperate with the sliding wall 212, so that the light-emitting member 24 and the sliding member 232 can move synchronously with respect to the sliding rail 210 when the sliding member 232 slides on the sliding rail 210 along the first direction.

The limiting protrusion 234 may be disposed above the sliding wall 212, and since the bottom of the sliding member 232 (i.e., the side contacting with the sliding channel 211) slides on the sliding channel 211, if the sliding member 232 is relatively high, the limiting groove 233 may have a problem of motion lag, so that the light-emitting member 24 and the imprint head 30 may not move synchronously at different motion rates, and by disposing the limiting protrusion 234, the problem of motion lag of the limiting groove 233 may be effectively prevented, so as to improve the synchronization between the light-emitting member 24 and the imprint head 30. The limiting protrusion 234 can keep the sliding member 232 balanced so that the sliding member 232 does not shake during the moving process, thereby keeping the light emitting member 24 stable during the moving process.

In some embodiments, the limiting protrusions 234 include a first limiting protrusion 2341 and a second limiting protrusion 2342, and the first limiting protrusion 2341 and the second limiting protrusion 2342 are symmetrically disposed at both sides of the sliding member 232.

The first limiting protrusion 2341 and the second limiting protrusion 2342 are symmetrically arranged on two sides of the sliding part 232, that is, the first limiting protrusion 2341 and the second limiting protrusion 2342 are respectively located above the sliding walls 212 on two sides, so that the problem of motion lag of the limiting groove 233 can be effectively prevented by the first limiting protrusion 2341 and the second limiting protrusion 2342 arranged on two sides, the synchronism of the light-emitting member 24 with the stamping head 30 can be improved, and the light-emitting member 24 can be balanced.

In some embodiments, as shown in fig. 12, the slide rail 210 includes a first slide rail 213 and a second slide rail 214, the sliding member 232 includes a first sliding member 2321 and a second sliding member 2322, and the light emitting member 24 is disposed on the first sliding member 2321 and the second sliding member 2322; the first sliding member 2321 is disposed on the first sliding rail 213, the second sliding member 2322 is disposed on the second sliding rail 214, and the first sliding member 2321 and the second sliding member 2322 are fixedly connected.

When the imprinting apparatus 100 works, the driving member 231 is driven to move by the driving motor 230, the driving member 231 moves and drives the first sliding member 2321 to slide relative to the first sliding rail 213, because the first sliding member 2321 is fixedly connected with the second sliding member 2322, the first sliding member 2321 slides and drives the second sliding member 2322 to slide relative to the second sliding rail 214, and drives the light emitting member 24 to move along with the sliding member 232 relative to the bearing plate 22, so that the light emitted by the light emitting member 24 passes through the light transmitting member to irradiate the substrate, and the imprinting glue imprinted with the submicron-level pattern on the substrate is cured.

Specifically, the first slide rail 213 and the second slide rail 214 may be disposed at the bottom of both ends of the light emitting element 24, so that the light emitting element 24 may be stably fixed on the first sliding member 2321 and the second sliding member 2322, and the light emitting element 24 may not drop due to unbalance during the movement.

In some embodiments, as shown in fig. 13, the first sliding member 2321 and the second sliding member 2322 are fixedly connected by a connecting portion 2323, the connecting portion 2323 is provided with a placement groove 2324, the placement groove 2324 faces the loading plate 22, and the placement groove 2324 is used for placing the light-emitting member 24.

Wherein, the cross section of the placement groove 2324 may be in the shape of a circular arc. The cross-sectional shape of the placement groove 2324 may match the cross-sectional shape of the limiting groove 233, so that the light-emitting element 24 may be placed in the placement groove 2324 and the limiting groove 233, and thus the light-emitting element 24 may be attached to the placement groove 2324 and the limiting groove 233 and placed in the placement groove 2324 and the limiting groove 233.

In some embodiments, as shown in fig. 14, the light emitting element 24 includes a light emitting tube 240 and a lamp housing 241, the light emitting tube 240 is disposed in the lamp housing 241, and the lamp housing 241 is in a position-limited fit with the positioning slot 2324.

Specifically, if the number of the sliding members 232 is 1, the lamp shade 241 is in limit fit with the limit groove 233; if the number of the sliding pieces 232 is more than 1, the lamp shade 241 is in limit fit with the placing groove 2324 and the limiting groove 233.

The light emitting tube 240 may be any light emitting tube for implementing light curing, for example, an ultraviolet curing tube may be used, and when the ultraviolet curing tube is used, the imprint glue on the substrate should be a corresponding ultraviolet curing glue. The ultraviolet curing lamp tube can emit ultraviolet rays with specific wavelength, can realize ultraviolet curing within 0.5-2 seconds, and has the advantages of instant curing, time and electricity saving, space saving, easy control, no need of high-temperature baking, no pollution and the like.

The light-emitting tube 240 is disposed in the lamp cover 241 to protect the light-emitting tube 240 from being broken due to collision of an external object, and the lamp cover 241 can block ultraviolet light to protect an equipment operator from being damaged by ultraviolet radiation.

Illustratively, since the light emitting tube 240 has a generally cylindrical shape and the lamp shade 241 is used to protect the light emitting tube 240, the light emitting tube 240 is generally covered, and thus the lamp shade 241 has a generally cylindrical shape. The side of the light shade 241 facing away from the bearing plate 22 is in spacing fit with the spacing groove 233 and the placing groove 2324, so that the light shade 241 is fixedly mounted on the placing groove 2324 and the spacing groove 233.

For example, the lamp shade 241 may be fixedly mounted on the placement groove 2324 and the limiting groove 233 by clamping or welding, so that the light emitting tube 240 is aligned with the bearing plate 22, and light emitted by the light emitting tube 240 is aligned with the light transmitting member, thereby improving the curing effect.

In some embodiments, a connection port is disposed in the limiting groove 233, and the light-emitting lamp 240 is electrically connected to the connection port.

Specifically, when the apparatus is in operation, that is, when light is cured, the heating member 32 of the imprint head 30 does not need to be heated, the control system of the main body 10 of the screen printing machine controls the imprint head 30 to apply pressure to the printing plate 50 and move to achieve scratch printing, meanwhile, the driving member 231 is driven by the driving motor 230 to move, the driving member 231 moves and drives the first sliding member 2321 to slide relative to the first sliding rail 213, because the first sliding member 2321 and the second sliding member 2322 are fixedly connected, the first sliding member 2321 slides and drives the second sliding member 2322 to slide relative to the second sliding rail 214, and drives the light-emitting member 24 to move relative to the bearing plate 22 along with the sliding member 232, and meanwhile, the control system of the main body 10 of the screen printing machine or the driving motor 230 controls the light-emitting tube 240 to emit light through the connection port, so that the light emitted by the light-emitting tube 240 irradiates the substrate through the light-transmitting member to cure the ultraviolet curing adhesive on which the pattern is imprinted on the substrate, thereby imprinting the sub-micron pattern 51 on the printing plate 50 onto the uv imprinting glue on the substrate.

In some embodiments, the lamp cover 241 includes a light-transmitting portion 242, the light-transmitting portion 242 being disposed at a side of the lamp cover 241 near the bearing plate 22; wherein, the light that light-emitting tube 240 sent shines on the printing opacity piece through printing opacity portion 242, light shines through the printing opacity piece and shines the substrate, in order to right the impression glue of the pattern of impression submicron level on the substrate solidifies.

Specifically, the light-transmitting portion 242 is a linear light-transmitting portion, and the light-transmitting portion 242 matches the shape of the contact portion 31 of the platen head 30. Therefore, the light-emitting lamp tube 240 can keep emitting light, photocuring can be carried out while imprinting, and the imprinting efficiency is greatly improved.

Meanwhile, light emitted by the light emitting tube 240 can only irradiate the light transmission member through the light transmission portion 242, the light transmission portion 242 is located below the imprinting head 30, and the light emitting direction is directly opposite to the imprinting glue at the imprinted portion during operation, so that the imprinting glue at the imprinted portion can be cured by ultraviolet rays penetrating through the light transmission member, and the imprinting glue at the imprinted portion cannot affect the imprinting glue in an un-imprinted area during ultraviolet curing because the light transmission portion 242 is a linear light transmission portion.

In some embodiments, the lamp cover 241 is notched, and the light-transmitting portion 242 is formed through the notch. This makes it possible to obtain the light-transmitting portion 242 simply by notching, thereby reducing the manufacturing cost.

Wherein the circumferential angle corresponding to the notch is 45 °, so that the light-transmitting portion 242 can be configured as a linear light-transmitting portion by configuring the circumferential angle corresponding to the notch to be 45 °, and the circumferential angle corresponding to the notch can be configured according to the shape of the contact portion 31 of the imprint head 30, for example, the circumferential angle corresponding to the notch is 30 ° or 60 °, so that the light-transmitting portion 242 matches the shape of the contact portion 31 of the imprint head 30.

In some embodiments, the optically transparent member may be a quartz plate.

In some embodiments, as shown in FIG. 15, the entire carrier plate 22 is a light transmissive member, i.e., a quartz plate. A plurality of through-hole parts 220 may be provided on the carrier plate 22, and the through-hole parts 220 are used to fix the substrate on the carrier plate 22 using the adsorption force of gas.

Illustratively, the plurality of through holes 220 may be equidistantly arranged on the carrier plate 22, thereby improving the suction effect of the substrate.

In some embodiments, as shown in fig. 16, the carrier 22 has an opening 221, the opening 221 has a position-limiting portion 222, the carrier 22 has a plurality of through holes 220, the through holes 220 are distributed around the opening 221, the through holes 220 are used for fixing the substrate to be imprinted on the carrier 22 by using the adsorption force of the gas, the light-transmitting member is disposed at the opening 221, the position-limiting portion 222 is used for limiting and matching with the light-transmitting member, and the carrier 22 and the light-transmitting member are made of different materials.

If a whole quartz plate is used as the carrier plate, the substrate needs to be punched on the quartz plate in order to be adsorbed on the carrier plate. Because the atress of quartz plate is not so than the metal sheet, and the quartz plate is not fit for punching moreover, and the operation of punching can form very big stress in quartz plate inside for the quartz plate leaves very easily at the impression in-process, influences the impression effect, and the cost that utilizes a monoblock quartz plate to do the loading board simultaneously is also than higher. Therefore, the carrier plate 22 can be provided with the opening 221, and the light-transmitting member is disposed at the opening 221, so that the substrate to be imprinted can be fixed on the carrier plate 22 by only punching the carrier plate 22 without punching the light-transmitting member (i.e., the quartz plate), and the imprinting effect can be prevented from being affected by the breakage of the quartz plate during the operation.

Illustratively, the light-transmitting member is a quartz plate, and the material of the carrier plate 22 is a metal material. And the loading board 22 adopts metal material such as aluminum plate, for using the quartz plate as the loading board, the cost is lower, and aluminum plate's atress is better, and the stress influence that punches on aluminum plate and form can be ignored.

In some embodiments, the length of the slide rail 210 is greater than the length of the opening 221 in the first direction.

Since the light-transmitting sheet is disposed at the opening, only the light-transmitting sheet can transmit the light emitted from the light-emitting member 24 to the substrate, and the carrier 22 is opaque, the moving range of the sliding member 232 only needs to be slightly longer than the length of the opening 221 in the first direction, so that the length of the sliding rail 210 can be slightly longer than the length of the opening 221 in the first direction.

In some embodiments, the screen printing based uv curing imprinting stage 20 further comprises a supporting pillar 25, wherein the supporting pillar 25 is used for cooperating with the carrier plate 22 to fixedly mount the carrier plate 22 at a predetermined height. Compared with the existing ultraviolet curing imprinting platform, the ultraviolet curing imprinting platform has the advantages that the space can be greatly saved, the space utilization rate is improved, and the material and manufacturing cost are saved.

Specifically, as shown in fig. 9, the supporting column 25 can be used to support the carrier plate 22 and fixedly mount the carrier plate 22 at a predetermined height, so as to place the driving assembly 23 and the light emitting member 24 under the carrier plate 22.

For example, the supporting column 25 can be engaged with the loading plate 22 by clipping, screwing, welding, or the like, so as to fix the loading plate 22 at a predetermined height.

For example, the corresponding support pillars 25 may be disposed at four corners of the supporting board 22 to fix the supporting board 22 at a predetermined height, so as to ensure the stability of the supporting board 22.
