Description

Technical Field

[0001] This invention relates to the field of high-end equipment manufacturing technology, specifically to a vertical digital exposure (LDI) device and exposure system that facilitates the placement and removal of circuit boards. Background Technology

[0002] Currently, most digital exposure (LDI) equipment in the industry uses a single-sided exposure method. This involves placing the circuit board on the LDI equipment's work frame, flattening and fixing it to the frame using vacuuming and edge pressing, and then scanning to expose the first side. Then, manually or automatically, the circuit board is flipped and placed back on the LDI equipment's work frame, flattened and fixed again using vacuuming and edge pressing, and then scanning to expose the second side. This method suffers from several persistent problems:

[0003] When placing a circuit board on a work frame, it needs to be vacuumed from the bottom to flatten the circuit board onto the work frame. However, some double-sided multilayer boards have many holes, and the inside of the holes is protected by ink plugs. Vacuuming from the bottom will suck out the ink inside the holes, causing the plugs to leak and become defective.

[0004] Based on the problem mentioned in the first point, many equipment manufacturers reduce the vacuum level by adding frequency converters to control the vacuum pump or blower. Combined with the four-sided pressure plate method, this prevents the ink in the hole from being sucked out during vacuuming. However, after the vacuum level and suction force are reduced, the circuit board cannot be flattened on the work frame, resulting in poor exposure effect.

[0005] The circuit board is placed on the work frame, and it is in direct contact with the adsorption panel on the frame. Because the ink on the circuit board is not completely dry, it often sticks to the adsorption panel after a period of use, causing poor copper exposure. Furthermore, to reduce this problem, the adsorption panel needs a high-level anti-stick treatment. This high-level anti-stick treatment is very expensive and only lasts for two to three months, significantly increasing hardware costs. Even then, it does not completely solve the problem of poor copper exposure.

[0006] Fourth, the circuit board is placed horizontally, while the exposure components need to be placed vertically. The lens on the lower exposure component needs to face upwards to expose the circuit board, which makes the lens elements easily contaminated with dust, resulting in poor exposure. Furthermore, the lower exposure component is difficult to adjust and maintain.

[0007] Fifth, to meet exposure requirements, the circuit board needs to be kept flat. If the circuit board is placed horizontally and a tensioning device is used to flatten it, gravity will not be able to effectively flatten the circuit board in the horizontal direction. Summary of the Invention

[0008] In view of the shortcomings of low replacement efficiency in the existing technology, the purpose of this invention is to provide a vertical digital exposure (LDI) device that is easy to replace and easy to pick up and put down circuit boards.

[0009] To address the above problems, the present invention provides the following technical solution:

[0010] In one aspect, embodiments of this application provide a vertical digital exposure (LDI) device that facilitates the placement and removal of circuit boards, including: a support base;

[0011] An exposure assembly, erected on the support base, is used to expose the workpiece;

[0015] In some embodiments, when the workpiece is mounted on the frame portion, the angle between the workpiece and the support base is 30-90 degrees.

[0016] In some embodiments, the angle between the frame portion and the support base is 30-90 degrees.

[0017] In some embodiments, the shape of the through hole includes, but is not limited to, square, circular, and elliptical.

[0018] In some embodiments, the number of through holes on the frame portion is greater than or equal to one, and each through hole can be used to mount at least one of the workpieces.

[0019] In some embodiments, the device further includes a drive mechanism that can drive the frame portion to move in the exposure scanning direction, and / or the drive mechanism can drive the exposure component to move in the exposure scanning direction.

[0020] In some embodiments, the exposure component includes a first exposure section and a second exposure section;

[0021] The first surface is close to the first exposure area, and the second surface is close to the second exposure area;

[0022] The first exposure unit can emit an exposure beam onto the first surface, thereby exposing one side of the workpiece mounted in the frame unit;

[0023] The second exposure unit can emit an exposure beam onto the second surface, thereby exposing the other side of the workpiece mounted in the frame unit.

[0024] In some embodiments, the number of the frame portions is greater than or equal to two.

[0025] In some embodiments, the frame portion includes a fastener, a clamping element, and a traction mechanism;

[0026] The fixing member is used to fix one side of the workpiece; the clamping member is used to clamp the other side of the workpiece; and the traction mechanism can drive the workpiece to move away from the fixing member.

[0027] In some embodiments, the frame portion includes a fastener and a tension mechanism;

[0028] The fastener is used to fix one side of the workpiece; the tension mechanism is used to connect the other side of the workpiece and stretch the other side of the clamping member to move away from the fastener.

[0029] In some embodiments, the device further includes a positioning component;

[0030] The positioning component is used to position the workpiece installed in the frame section.

[0031] In another aspect, embodiments of this application provide an exposure system, including a first pick-and-place mechanism, a second pick-and-place mechanism, and a vertical digital exposure (LDI) device for easy pick-and-place of circuit boards as described in any of the first aspects;

[0032] The first pick-and-place mechanism is used for installing workpieces within the frame section; the second pick-and-place mechanism is used for removing workpieces from the frame section.

[0033] In some embodiments, the second pick-and-place mechanism removes the workpiece from the second surface of the frame portion, and the first pick-and-place mechanism mounts the workpiece from the first surface of the frame portion.

[0034] The beneficial effects of this invention are: by placing the workpiece in the through hole on the upright frame, the workpiece is made upright, so there is no need to lay the workpiece flat. Therefore, there is no need to worry about the ink on the workpiece being sucked out and resulting in poor exposure effect when the workpiece is laid flat and vacuumed to ensure its flatness.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0058] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0059] like Figures 1-2 As shown, this embodiment provides a vertical digital exposure (LDI) device for easy placement and removal of circuit boards. It includes a support base 110, an exposure assembly 120, and a frame. The exposure assembly 120 is disposed on the support base 110 and is used to expose workpieces. The frame stands upright on the support base 110 and includes through holes penetrating its first and second surfaces. In other words, by placing the frame upright on the support base 110, the first and second surfaces are also upright on the support base 110, reducing the lateral space occupied by the device 100. By placing the workpiece in the through holes on the upright frame, the workpiece remains upright, eliminating the need for it to be laid flat. This avoids the problem of ink being sucked out and resulting in poor exposure when the workpiece is laid flat and vacuumed to ensure flatness. Furthermore, it solves the problem of dust easily falling onto the lower exposure lens during double-sided exposure when the workpiece is laid flat, affecting subsequent exposure results. Additionally, the upright frame with through holes facilitates subsequent workpiece handling.

[0060] like Figures 1-4As shown, in some embodiments, the frame portion is vertically disposed on the support base 110. However, this application is not limited to this, and the frame portion may also be disposed at an angle to the support base 110. Whether the frame portion is disposed vertically to the support base 110 or at an angle to the support base 110, it can perform normal operation well and is equally easy to operate.

[0061] The workpiece is installed in the frame, so it can be placed vertically or tilted relative to the support 110. By placing the workpiece vertically or tilted, there is no need for the vacuuming process required when placing it flat, thus eliminating concerns about ink being sucked out.

[0062] The angle between the frame and the support base 110 is 30-90 degrees. That is, when installing the workpiece, the angle between the frame and the support base 110 can be 30-90 degrees.

[0063] The workpiece is installed in the frame section, and the angle between the frame section and the support base 110 is 30-90 degrees. Therefore, when the workpiece is installed in the frame section, the angle between the workpiece and the support base 110 is 30-90 degrees, ensuring normal operation of subsequent exposure processes.

[0064] For example, the angle between the frame portion and the support base 110 can be 30 degrees, 45 degrees, 60 degrees, 75 degrees, or 90 degrees.

[0065] The shape of the through hole includes, but is not limited to, square, round, and elliptical shapes. That is to say, in order to process different workpieces, through holes of square, round, elliptical, or other shapes can be selected according to requirements to facilitate installation and removal. However, this application is not limited to this; the through hole can also be parallelogram or irregular in shape, and can be selected as needed. This application does not impose any restrictions.

[0066] The frame section has through holes, through which workpieces are inserted from one side of the frame section for exposure. After exposure, the workpieces are removed from the other side. At the same time as the workpieces are removed, the next workpiece is promptly inserted from one side of the frame section. The removal and insertion of workpieces do not interfere with each other, which greatly improves the replacement efficiency and thus the exposure efficiency.

[0067] Optionally, the frame section has one or more through holes, and each through hole can be used to mount at least one workpiece. By having at least one through hole on each frame section, multiple workpieces can be exposed simultaneously; and by mounting at least one workpiece in each through hole, one or more workpieces can be mounted in a single through hole according to the size of the workpiece, thus improving the utilization rate of the frame section.

[0068] like Figures 1-3As shown, in some embodiments, the device further includes a drive mechanism that can drive the frame portion to move in the exposure scanning direction, and / or drive the exposure assembly 120 to move in the exposure scanning direction. That is, the frame portion and / or the exposure assembly 120 can be driven; causing the frame portion to move to the exposure area of ​​the exposure assembly 120 and / or causing the exposure assembly 120 to move to the exposure area of ​​the exposure assembly 120, thereby ensuring normal exposure.

[0069] like Figures 1-3 As shown, in an optional embodiment, only the frame portion is movable, while the exposure assembly 120 is fixed, that is, the exposure assembly 120 is fixedly mounted on the support base 110. The frame portion is driven by the driving mechanism to move along the exposure scanning direction, so that the workpiece is moved to the exposure area of ​​the exposure assembly 120 for exposure, or moved out of the exposure area for workpiece loading and unloading.

[0070] like Figure 4 As shown, when both the frame and the exposure assembly 120 are movable, that is, the frame is driven by the drive mechanism to move along the exposure scanning direction, so that the workpiece is moved to a general exposure area of ​​the exposure assembly 120. Then the drive mechanism will drive the exposure assembly to move again, so that the workpiece is accurately exposed. After that, the drive mechanism drives the frame to move out of the exposure area to pick up and put down the workpiece.

[0071] In other embodiments, when the frame is fixed and the exposure component 120 is movable, that is, when the frame is fixedly mounted on the support base 110, the exposure component 120 is driven by the driving mechanism to move along the exposure scanning direction, so that the exposure component 120 moves to the exposure area of ​​the workpiece to expose the workpiece, or the exposure component 120 moves out of the exposure area to make the workpiece easy to pick up and put down.

[0072] like Figures 1-3 As shown, in this embodiment, the exposure assembly 120 includes a first exposure unit 121 and a second exposure unit 122; a first surface is close to the first exposure unit, and a second surface is close to the second exposure unit; the first exposure unit 121 can emit an exposure beam onto the first surface to expose one side of the workpiece mounted in the frame; the second exposure unit 122 can emit an exposure beam onto the second surface to expose the other side of the workpiece mounted in the frame. By using the first exposure unit 121 and the second exposure unit 122 to simultaneously expose both sides of the workpiece in the frame, there is no need for flipping, and the double-sided exposure of the workpiece is completed in one go, saving the time spent on flipping and further accelerating the exposure efficiency.

[0073] The number of frame sections is two or more. For example... Figures 1-4The system comprises two frame sections, namely the first frame section 130 and the second frame section 140. By employing multiple frame sections, while a workpiece is being exposed on one frame section, the other frame sections can handle the loading and unloading of the workpiece; this enables alternating operations without stopping the machine, thereby improving exposure efficiency.

[0074] like Figures 1-3 As shown, taking a frame section including a first frame section 130 and a second frame section 140 as an example, the frame section includes a first frame section 130 and a second frame section 140; the first frame section 130 includes a first mounting part 132, and the second frame section 140 includes a second mounting part 142; the first frame section 130 and the second frame section 140 are disposed on a support base 110, the first mounting part 132 is mounted inside the first frame section 130, and the second mounting part 142 is mounted inside the second frame section 140; the driving mechanism includes a first driving component and a second driving component; the first driving component is used to drive the first frame section 130 to move in the exposure scanning direction; the second driving component is used to drive the second frame section 140 to move in the exposure scanning direction. In other words, by using the first frame section 130 to move in the exposure scanning direction via the first driving component and the second frame section 140 to move in the exposure scanning direction via the second driving component, the exposure operation is performed through the two frame sections, which can save waiting time and speed up the exposure efficiency.

[0075] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a first control unit, which controls the first driving component and the second driving component to drive the first frame portion 130 and the second frame portion 140 to move alternately. That is, when the first driving component drives the first frame portion 130 to move in the exposure scanning direction, the second driving component drives the second frame portion 140 to move away from the exposure scanning direction; similarly, when the first driving component drives the first frame portion 130 to move away from the exposure scanning direction, the second driving component drives the second frame portion 140 to move in the exposure scanning direction. By driving the first frame portion 130 and the second frame portion 140 to move alternately by the first driving component and the second driving component, it can be ensured that one workpiece is exposed and another workpiece is replaced at the same time, reducing the downtime for removing and replacing workpieces after exposure and speeding up the exposure efficiency.

[0076] like Figures 1-3As shown, in this embodiment, the first driving assembly includes a first track 151 and a first driving mechanism; the first track 151 is disposed on the support base 110; the first frame portion 130 is mounted on the first track 151, and the first driving mechanism drives the first frame portion 130 to move along the first track 151; the second driving assembly includes a second track 161 and a second driving mechanism; the second track 161 is disposed on the support base 110; the second frame portion 140 is mounted on the second track 161, and the second driving mechanism drives the second frame portion 140 to move along the second track 161. Using tracks to move the first frame portion 130 and the second frame portion 140 effectively ensures the stability of the displacement of the first frame portion 130 and the second frame portion 140.

[0077] As an example, both the first and second drive mechanisms may include a rack, a gear, and a first motor. The first motor is mounted on the first frame portion 130 and the second frame portion 140, respectively, and the gear is mounted on the first motor. The rack is mounted on the first track 151 and the second track 161, respectively. The rotation of the first motor drives the first frame portion 130 and the second frame portion 140 to move along the tracks via the gear and rack. Using a rack and pinion mechanism to drive the movement of the first frame portion 130 and the second frame portion 140 can effectively ensure the stability of the first frame portion 130 and the second frame portion 140. At the same time, using a rack and pinion mechanism allows the mechanism to stop after moving to an accurate position, ensuring the accuracy of the exposure.

[0078] like Figures 1-3 As shown, in some embodiments, the first track 151 and the second track 161 are located between the first exposure section 121 and the second exposure section 122.

[0079] However, this application is not limited to parallel implementations. For example, the first track 151 and the second track 161 are parallel tracks within the exposure range of the first exposure section 121 and the second exposure section 122, but the distance between the first track 151 and the second track 161, which are not within the exposure range of the first exposure section 121 and the second exposure section 122, gradually increases or gradually decreases.

[0080] Different track settings can be implemented according to the specific circumstances of the equipment, and this application does not impose any restrictions.

[0081] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a third driving mechanism and a fourth driving mechanism; the third driving mechanism is used to drive the first exposure unit 121 to move closer to or away from the first track 151; the fourth driving mechanism is used to drive the second exposure unit 122 to move closer to or away from the second track 161. By using the third driving mechanism to drive the first exposure unit 121 to move and the fourth driving mechanism to drive the second exposure unit 122 to move, the distance between the workpiece and the two exposure units is adjusted, ensuring the accuracy of the exposure.

[0082] like Figures 1-3 As shown, in this embodiment, the device further includes a second control unit; the second control unit controls the movement of the third drive mechanism and the fourth drive mechanism; when the first frame portion 130 moves into the exposure range of the exposure assembly 120, the second control unit controls the movement of the first exposure portion 121 and / or the second exposure portion 122, so that the workpiece mounted on the first frame portion 130 or the second frame portion 140 is located in the exposure area of ​​the first exposure portion 121 and the second exposure portion 122. By controlling the movement of the first exposure portion 121 and / or the second exposure portion 122 by the second control unit, the workpiece is placed in the area to be exposed, ensuring the accuracy of the exposure.

[0083] like Figures 1-3 As shown, in this embodiment, the first frame portion 130 includes a first frame 131 and a first mounting portion 132; the second frame portion 140 includes a second frame 141 and a second mounting portion 142; the first frame 131 is mounted on the first track 151, and the first mounting portion 132 is located within the first frame 131; the workpiece can be mounted to the first mounting portion 132 via one side or the other side of the first frame 131, and the workpiece can be removed from the first mounting portion 132 via one side or the other side of the first frame 131; the second frame 141 is mounted on the second track 161, and the second mounting portion 142 is located within the second frame 141; the workpiece can be mounted to the second mounting portion 142 via one side or the other side of the second frame 141, and the workpiece can be removed from the second mounting portion 142 via one side or the other side of the second frame 141. The frame structure provides support for the workpiece and prevents exposure deviations; the design of the mounting portion effectively allows for double-sided exposure of the workpiece.

[0084] like Figures 1-3 As shown, in some embodiments, both the first mounting portion 132 and the second mounting portion 142 of the frame include a fixing member 1a, a clamping member 1b, and a traction mechanism 1c. The fixing member 1a is used to fix one side of the workpiece; the clamping member 1b is used to clamp the other side of the workpiece, and the traction mechanism can drive the clamping member to move away from the fixing member. That is, the workpiece is first fixed by the fixing member 1a and the clamping member 1b, and then the clamping member 1b is moved by the traction mechanism 1c to ensure the flatness of the workpiece and prevent the workpiece from bending due to not being flattened, which would affect the exposure accuracy. At the same time, after clamping from both sides, the traction mechanism 1c tightens the workpiece, and the flatness is no longer maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0085] like Figure 7As shown, in some embodiments, the fixing member 1a includes a first pressure plate 1a1, a first permanent magnet, and a first electromagnet 1a3; the first frame 131 and the second frame 141 each include a first pressure plate 1a1 placed on one side thereon, and the first permanent magnet is mounted on the first pressure plate 1a1; the first frame 131 and the second frame 141 are respectively equipped with the first electromagnet 1a3; when a positive current is applied to the first electromagnet 1a3, the first permanent magnet 1a2 and the first electromagnet 1a3 attract each other, which can fix and clamp the workpiece; when a reverse current is applied, the first permanent magnet 1a2 and the first electromagnet 1a3 repel each other, and the workpiece can be removed. The clamping component 1b includes a support plate 1b1, a second pressure plate 1b2, a second permanent magnet, and a second electromagnet 1b4. The support plate 1b1 is mounted on the other side of the first frame 131 and the second frame 141, respectively. The second pressure plate 1b2 is mounted on the support plate 1b1, and the second permanent magnet is mounted on the second pressure plate 1b2. The second electromagnet 1b4 is mounted on the support plate 1b1. When a positive current is applied to the second electromagnet 1b4, the second permanent magnet 1b3 and the second electromagnet 1b4 attract each other, thus clamping and fixing the workpiece. When a reverse current is applied, the second permanent magnet 1b3 and the second electromagnet 1b4 repel each other, and the workpiece can be removed. Through the combined use of the electromagnet and the permanent magnet, the clamping or separation of the workpiece can be achieved quickly.

[0086] like Figure 6 As shown, in an optional embodiment, the traction mechanism 1c includes a second motor 1c11, a rotating shaft 1c12, a conveyor belt 1c13, and a sliding rod 1c14. The second motor 1c11 and the rotating shaft 1c12 are located on the sides of the first frame 131 and the second frame 141 near the clamping member 1b, respectively. The conveyor belt 1c13 and the sliding rod 1c14 are located on both sides of the clamping member 1b, respectively. The two sides of the clamping member 1b are mounted on the sliding rod 1c14. The second motor 1c11 drives the rotating shaft 1c12 to rotate, and the rotating shaft 1c12 drives the conveyor belt 1c13 to rotate. The conveyor belt 1c13 drives the clamping member 1b to move along the sliding rod 1c14, so that the clamping member 1b moves closer to or further away from the fixing member 1a. By using the conveyor belt 1c13 to drive the clamping part to move, the flatness of the workpiece can be ensured, thereby ensuring the exposure accuracy of the workpiece.

[0087] like Figure 7As shown, in another embodiment, the traction mechanism 1c includes a third motor 1c21, a tension spring 1c22, a guide rod 1c23, and a pull rope 1c24. The guide rod 1c23 is located on both sides of the clamping member 1b. The two sides of the clamping member 1b are mounted on the guide rod 1c23. The tension spring 1c22 is sleeved on the guide rod 1c23, and the lower end of the tension spring 1c22 is fixed to the clamping member 1b. The tension spring 1c22 provides an upward force to the clamping member 1b, allowing the clamping member 1b to move upward and be stretched and fixed to the lower side of the clamping member 1b. The third motor 1c21 is mounted on the lower side of the frame. The rotation of the third motor 1c21 can drive the stretching and retraction. That is, the motor pulls down the pull rope 1c24, thereby causing the clamping member 1b to move downward, tightening the workpiece fixed on the clamping member 1b, ensuring the flatness of the workpiece, and thus ensuring the exposure accuracy of the workpiece.

[0088] In another embodiment, both the first mounting portion 132 and the second mounting portion 142 of the frame include a fixing member and a tension mechanism 1d; the fixing member 1a is used to fix one side of the workpiece; the tension mechanism 1d is used to connect the other side of the workpiece and stretch the other side of the workpiece away from the fixing member 1a. That is, after one side of the workpiece is fixed by the fixing member, the other side of the workpiece is fixed by the tension mechanism 1d and pulled away from the fixing member, so that the workpiece is flattened and prevented from bending due to not being flattened, which would affect the exposure accuracy; at the same time, by fixing one side and tightening the workpiece on the other side, the flatness is no longer maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0089] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a positioning component 170; when the workpiece moves towards the exposure component 120 along with the first frame portion 130 or the second frame portion 140, the positioning component 170 can position the workpiece; the workpiece is provided with target points. When the workpiece passes the positioning component 170, the positioning component 170 will identify the target points on the workpiece, determine the precise exposure position based on the target points, and then feed back to the exposure component 120, so that the exposure component 120 can accurately expose the workpiece, ensuring the accuracy of the exposure.

[0090] The workpiece is a circuit board, which includes PCB boards, FPC boards, etc.

[0091] The first motor, the second motor 1c11, and the third motor 1c21 are all three-phase asynchronous motors.

[0092] Figure 3The second pick-and-place mechanism 220 removes the workpiece from the second surface of the frame section, while the first pick-and-place mechanism 210 mounts the workpiece from the first surface of the frame section. In other words, by having the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 located on opposite sides of the frame section, a workpiece can be removed from one side while being placed in the other, achieving a tight fit. This saves time compared to separate installation and pick-and-place operations, speeds up replacement efficiency, and ensures constant readiness for exposure.

[0093] However, this application is not limited to this. The first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 can be located on the same side of the frame part and pick up and place workpieces on the same side.

[0094] In some embodiments, the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 are robotic arms, which can be mounted on the support base 110 with the movable end of the robotic arm facing upward.

[0095] Figure 3 The robot arm is mounted on the surface of the support base, but this application is not limited to this. The robot arm can also be set above the support base 110, with the moving end of the robot arm facing downward.

[0096] The robotic arm can be part of a digital exposure LDI device or a robotic arm on a robot that is independent of the digital exposure LDI device; this application does not impose any restrictions.

[0097] In this configuration, if the first pick-and-place mechanism 210 is responsible for retrieving the workpiece and the second pick-and-place mechanism 220 is used for installing the workpiece, then after the first pick-and-place mechanism 210 grips the workpiece, it first moves away from the support base, for example, upwards, so that the workpiece will not collide with the frame when it rotates. Then, it rotates the workpiece from a vertical position to a horizontal position and places the workpiece horizontally in the placement area. After the second pick-and-place mechanism 220 retrieves the workpiece from the first pick-and-place mechanism 210, it can install the next workpiece in the frame and remove it after installation.

[0098] In summary, the present invention provides a vertical digital exposure (LDI) device and exposure system that facilitates the placement and removal of circuit boards. By placing the workpiece in the through-hole on the vertical frame, the workpiece is made upright, eliminating the need to lay the workpiece flat. This also eliminates the concern that when the workpiece is laid flat, the ink on the workpiece may be sucked out due to vacuum adsorption to ensure its flatness, resulting in poor exposure.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
