Description

Technical Field

[0001] This utility model relates to the field of high-end equipment manufacturing technology, specifically to a circuit board vertical left and right exchange frame digital exposure (LDI) device and exposure system. 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] First, when placing the circuit board on the work frame, it is necessary to use bottom vacuuming 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 plugging. Bottom vacuuming will suck out the ink inside the holes, causing the plugging to leak and become defective.

[0004] Secondly, 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 is to prevent 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] Third, 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. Utility Model Content

[0008] In view of the shortcomings of existing technologies that make it difficult to flatten the circuit board, the purpose of this utility model is to provide a high-efficiency circuit board vertical left and right exchange frame digital exposure (LDI) device and exposure system.

[0021] The second exposure unit can emit an exposure beam onto the second surface, thereby exposing the other side of the workpiece mounted in the first frame or the second frame.

[0022] In some embodiments, when the workpiece is mounted on the first frame or the second frame, the angle of the workpiece relative to the support is 30-90 degrees.

[0023] In some embodiments, the angle between the first frame portion and the second frame portion and the support base is 30-90 degrees.

[0058] 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.

[0059] 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 utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] 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.

[0061] like Figures 1-4As shown, this embodiment provides a vertical left-right switching frame digital exposure (LDI) device 100 for circuit boards, which includes a support base 110, an exposure assembly 120, a first frame portion 130, a second frame portion 140, and a drive assembly. The exposure assembly 120 is disposed on the support base 110 and is used to expose the workpiece; the first frame portion 130 is disposed perpendicular to or inclined to the support base 110 and is used to mount the workpiece and make the workpiece vertical or inclined; the second frame portion 140 is disposed perpendicular to or inclined to the support base 110 and is used to mount the workpiece and make the workpiece vertical or inclined; the drive assembly is used to drive the first frame portion 130 and the second frame portion 140 to move in the exposure scanning direction; and / or drive the exposure assembly 120 to move in the exposure scanning direction. In other words, by placing the first frame portion 130 and the second frame portion 140 perpendicular to or inclined to the support base 110, the lateral space occupied by the digital lithography LDI equipment 100 can be reduced. By using a driving component to drive the first frame portion 130 and the second frame portion 140 to move in the exposure scanning direction, and / or driving the exposure component 120 to move in the exposure scanning direction, the two frames can alternately perform exposure operations, saving installation waiting time and improving exposure efficiency. Since the first frame portion 130 and the second frame portion 140 are perpendicular to or inclined to the support base 110, the workpiece is mounted vertically or inclined after being mounted on the first frame portion 130 or the second frame portion 140. Therefore, it is not necessary to lay the workpiece flat, and there is no need to worry about the ink on the workpiece being sucked out when the workpiece is laid flat and vacuumed to ensure flatness, resulting in poor exposure effect. In addition, it can also solve the problem that when double-sided exposure is performed flat, dust can easily fall on the exposure lens located on the lower side, affecting the effect of subsequent exposure.

[0062] like Figures 1-3 As shown, in this embodiment, when the first frame portion 130 and the second frame portion 140 are movable and the exposure component 120 is fixed, that is, when the exposure component 120 is fixedly installed on the support base 110, the first frame portion 130 or the second frame portion 140 is driven by the driving component to move along the exposure scanning direction, so that the workpiece is moved to the exposure area of ​​the exposure component 120 for exposure, or moved out of the exposure area for workpiece pick-up and drop.

[0063] like Figure 4 As shown, in this embodiment, when the first frame portion 130, the second frame portion 140, and the exposure component 120 are all movable, that is, the first frame portion 130 or the second frame portion 140 is driven by the driving component to move along the exposure scanning direction, so that the workpiece is moved to a general exposure area of ​​the exposure component 120. Then the driving component will drive the exposure component 120 to move again, so that the workpiece is accurately exposed. After that, the driving component drives the frame portion to move out of the exposure area to pick up and put down the workpiece.

[0064] In other embodiments, when the first frame portion 130 and the second frame portion 140 are fixed and the exposure component 120 is movable, that is, when the first frame portion 130 and the second frame portion 140 are fixedly installed on the support base 110, the exposure component 120 is driven by the driving component 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.

[0065] like Figures 1-3 As shown, in this embodiment, the exposure assembly 120 includes a first exposure section 121 and a second exposure section 122. The first exposure section 121 and the second exposure section 122 are located on both sides of the first frame section 130 and the second frame section 140. The first exposure section 121 and the second exposure section 122 can be used to perform double-sided exposure on the workpiece installed in the first frame section 130 or the second frame section 140. By using the first exposure section 121 and the second exposure section 122 to simultaneously perform double-sided exposure on the workpiece in the first frame section 130 or the second frame section 140, 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.

[0066] like Figures 1-3 As shown, in this embodiment, both the first frame portion 130 and the second frame portion 140 include through holes penetrating their first and second surfaces; the first surface is close to the first exposure portion 121, and the second surface is close to the second exposure portion 122; the first exposure portion 121 can emit an exposure beam onto the first surface, thereby exposing one side of the workpiece mounted in the first frame portion 130 or the second frame portion 140; the second exposure portion 122 can emit an exposure beam onto the second surface, thereby exposing the other side of the workpiece mounted in the first frame portion 130 or the second frame portion 140. By using the first exposure portion 121 and the second exposure portion 122 to simultaneously expose both sides of the workpiece within the first frame portion 130 or the second frame portion 140, 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.

[0067] like Figures 1-3 As shown, in some embodiments, the first frame portion 130 is disposed perpendicular to the support base 110 for mounting the workpiece and making the workpiece perpendicular to the support base 110; the second frame portion 140 is disposed perpendicular to the support base 110 for mounting the workpiece and making the workpiece perpendicular to the support base 110.

[0068] In other embodiments, the first frame portion 130 is inclined to the support base 110 for mounting the workpiece and tilting the workpiece relative to the support base 110; the second frame portion 140 is inclined to the support base 110 for mounting the workpiece and tilting the workpiece relative to the support base 110.

[0069] Whether the first frame portion 130 and the second frame portion 140 are set perpendicular to the support base 110 or inclined to the support base 110, they can improve the exposure efficiency compared to horizontal placement, eliminate the need for vacuum adsorption, and ensure the exposure effect.

[0070] When the workpiece is mounted on the frame, the workpiece is perpendicular to the support base 110 or inclined relative to the support base 110. By placing the workpiece vertically or at an incline, there is no need for the vacuuming operation required when laying it flat, and therefore there is no need to worry about ink being sucked out.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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, the exposure range of the exposure assembly 120 can be better utilized to expose the workpiece within each through hole, thus improving the utilization rate of the exposure assembly 120. Furthermore, by allowing at least one workpiece to be mounted in each through hole, one or more workpieces can be mounted within each through hole, depending on the size of the workpiece, further improving the utilization rate of the frame section.

[0075] The number of frame sections is greater than or equal to two, for example Figures 1-4 The system comprises two frame sections, namely a first frame section 130 and a 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 workpieces; this allows for alternating operations without stopping the machine, thus improving exposure efficiency.

[0076] 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 assembly includes a first driving assembly and a second driving assembly; the first driving assembly is used to drive the first frame section 130 to move in the exposure scanning direction; the second driving assembly 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 assembly and the second frame section 140 to move in the exposure scanning direction via the second driving assembly, the exposure operation is performed through two frame sections, which can save waiting time and speed up the exposure efficiency.

[0077] 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.

[0078] like Figures 1-3 As shown, in this embodiment, the first driving component includes a first track 151 and a first driving component; 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 component drives the first frame portion 130 to move along the first track 151; the second driving component includes a second track 161 and a second driving component; 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 component drives the second frame portion 140 to move along the second track 161. Using a track 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.

[0079] As an example, both the first and second drive components 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 move the first frame portion 130 and the second frame portion 140 effectively ensures the stability of the first frame portion 130 and the second frame portion 140. At the same time, the rack and pinion mechanism allows the components to stop at an accurate position, ensuring the accuracy of the exposure.

[0080] 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.

[0081] 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.

[0082] Different track settings can be implemented according to the specific circumstances of the equipment, and this application does not impose any restrictions.

[0083] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a third driving component and a fourth driving component; the third driving component is used to drive the first exposure unit 121 to move closer to or away from the first track 151; the fourth driving component 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 component to drive the first exposure unit 121 to move and the fourth driving component 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.

[0084] 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 driving component and the fourth driving component; when the first frame portion 130 moves into the exposure range of the exposure component 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.

[0085] like Figures 1-3As 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.

[0086] like Figure 4 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 pulls the workpiece tight, and the flatness is no longer maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0087] 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 mounted with first electromagnets 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.

[0088] 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.

[0089] 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.

[0090] 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 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. 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 not maintained by pressing and vacuuming, which can prevent the problem of ink being sucked out due to vacuuming.

[0091] like Figures 1-3 As shown, in this embodiment, the device 100 further includes a positioning component 170; when the workpiece moves toward 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.

[0092] The workpiece is a circuit board, which includes PCB boards, FPC boards, etc.

[0093] like Figure 3 As shown, this embodiment includes an exposure system, including a first pick-and-place mechanism 210 and a second pick-and-place mechanism 220; the first pick-and-place mechanism 210 is used for mounting workpieces within the frame section; the second pick-and-place mechanism 220 is used for removing workpieces from the frame section.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 mounting the workpiece, then after the first pick-and-place mechanism 210 grips the workpiece, it first moves away from the support, 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 it 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 then mount the next workpiece in the frame. After mounting, it moves the workpiece out, resulting in a short pick-and-place interval and high exposure efficiency.

[0100] In summary, this utility model provides a circuit board vertical left and right exchange frame digital exposure (LDI) device and exposure system. By placing the workpiece in the vertical or inclined first or second frame, the workpiece is made vertical or inclined, eliminating the need to lay the workpiece flat. This also eliminates the problem of ink being sucked out of the workpiece and resulting in poor exposure effect when the workpiece is laid flat and vacuumed to ensure its flatness.

[0101] 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.
