Description

Technical Field

[0001] The present invention relates to the technical field of high-end equipment manufacturing, and in particular to a vertical digital exposure LDI device and an exposure system for easily taking and placing a circuit board. Background Art

[0002] The current digital exposure LDI equipment in the industry is implemented by single-sided exposure, that is, the circuit board is placed on the working frame of the LDI equipment, and the board is sucked flat and fixed on the working frame by vacuuming and pressing the edge of the circuit board, and scanning exposure is performed to complete the exposure of the first side. Then, a manual or automatic flipping device turns the circuit board over and places it on the working frame of the LDI equipment, and the board is sucked flat and fixed on the working frame by vacuuming and pressing the edge of the circuit board, and scanning exposure is performed to complete the exposure of the second side. This method has the following major pain points that have not been solved: The circuit board is placed on the working frame, and the bottom vacuum is needed to suck the circuit board flat on the working frame. However, some double-sided multi-layer boards have many holes, and the inside of the holes are protected by ink plugging. Bottom vacuuming will suck out the ink in the holes, causing oil leakage from the plugging holes.

[0003] Based on the problem in the first point, many equipment manufacturers control the vacuum pump or blower by adding a frequency converter to reduce the vacuum degree of the vacuum pump, and combine it with the four-sided pressure plate to prevent the ink in the hole from being sucked out during vacuum suction. However, after the vacuum degree and suction force are reduced, the circuit board cannot be sucked flat on the working frame, resulting in poor exposure effect.

[0004] The circuit board is placed on the work frame, and the circuit board is in direct contact with the adsorption panel on the work frame. Since the ink on the circuit board is not completely dry, the ink often sticks to the adsorption panel after a period of use, resulting in poor copper exposure. In addition, in order to reduce the occurrence of this problem, the adsorption panel needs to be treated with a high level of anti-sticking. This high-level anti-sticking treatment is very expensive and can only last for two to three months, greatly increasing the hardware cost. Even so, it has not completely solved the problem of poor copper exposure.

[0005] Fourth, the circuit board is placed horizontally, and the exposure components need to be placed up and down. The lenses on the lower set of exposure components need to face upward to expose the circuit board. The lenses on the lenses are easily contaminated by dust, resulting in poor exposure effects, and the lower set of exposure components is difficult to debug and maintain later.

[0006] Fifth, in order to meet the 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 the circuit board, the circuit board cannot be effectively flattened in the horizontal direction due to the effect of gravity. Summary of the invention

[0007] In view of the disadvantage of low replacement efficiency in the prior art, the present invention aims to provide a vertical digital exposure LDI device that is easy to replace and easy to take and place circuit boards.

[0008] To solve the above problems, the present invention provides the following technical solutions: In one aspect, an embodiment of the present application provides a vertical digital exposure LDI device that is easy to take and place a circuit board, including: a support base; An exposure assembly, vertically arranged on the support seat, for exposing a workpiece; The frame part is erected on the support seat, and the frame part includes a through hole penetrating the first surface and the second surface of the frame part.

[0015] In some embodiments, the device further comprises a driving mechanism, wherein the driving mechanism can drive the frame portion to move in an exposure scanning direction, and / or the driving mechanism can drive the exposure component to move in an exposure scanning direction.

[0016] In some embodiments, the exposure assembly includes a first exposure section and a second exposure section; The first surface is close to the first exposure portion, and the second surface is close to the second exposure portion; The first exposure unit can emit an exposure beam to the first surface, thereby exposing one side of the workpiece installed in the frame unit; The second exposure section may emit an exposure beam to the second surface, thereby exposing the other side of the workpiece mounted in the frame section.

[0017] In some embodiments, the number of the frame portions is greater than or equal to two.

[0018] In some embodiments, the frame portion includes a fixing member, a clamping member, and a traction mechanism; 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 in a direction away from the fixing member.

[0019] In some embodiments, the frame portion includes a fixing member and a tension mechanism; The fixing member 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 in a direction away from the fixing member.

[0020] In some embodiments, the apparatus further comprises a positioning component; The positioning assembly is used to position a workpiece installed in the frame portion.

[0021] On the other hand, an embodiment of the present application provides an exposure system, including a first pick-and-place mechanism, a second pick-and-place mechanism, and a vertical digital exposure LDI device for easily picking up and placing a circuit board as described in any one of the first aspects; The first pick-and-place mechanism is used for installing the workpiece in the frame part; the second pick-and-place mechanism is used for taking out the workpiece in the frame part.

[0022] In some embodiments, the second pick-and-place mechanism takes out the workpiece from the second surface of the frame portion, and the first pick-and-place mechanism installs the workpiece from the first surface of the frame portion.

[0023] The beneficial effect of the present invention is that by placing the workpiece in the through hole on the upright frame part, the workpiece is made upright, and there is no need 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 the flatness of the workpiece, resulting in poor exposure effect.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] For the convenience of describing the first direction, the second direction and the third direction in the embodiment of the present application, the first direction is the left-right direction in the drawings, the second direction is the front-back direction in the drawings, and the third direction is the up-down direction in the drawings. The x-axis arrow direction is referred to as the "right" direction in the following text, the y-axis arrow direction is referred to as the "up" direction in the following text, and the z-axis arrow direction is referred to as the "back" direction in the following text, which is not limited to the actual application of the present application.

[0029] like Figure 1-Figure 2 As shown, this embodiment provides a vertical digital exposure LDI device that is easy to take and place circuit boards, which includes a support seat 110, an exposure assembly 120, and a frame part; the exposure assembly 120 is arranged on the support seat 110 for exposing workpieces; the frame part is erected on the support seat 110, and the frame part includes a through hole that penetrates the first surface and the second surface of the frame part. That is to say, the frame part is placed upright on the support seat 110, so that the first surface and the second surface are erected on the support seat 110, and the horizontal space occupied by the device 100 can be reduced, and the workpiece is placed in the through hole on the erected frame part, so that the workpiece is erected, and there is no need 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 placed flat and vacuumed to adsorb the workpiece to ensure the flatness of the workpiece, resulting in poor exposure effect; in addition, it can also solve the problem that when double-sided exposure is performed horizontally, dust is easily trapped on the exposure lens located on the lower side, which affects the effect of later exposure; in addition, the frame part is arranged upright and is provided with a through hole, which can also facilitate the subsequent placement of the workpiece.

[0030] like Figure 1-Figure 4 As shown, in some embodiments, the frame portion is vertically disposed on the support base 110. However, the present application is not limited thereto, and the frame portion can also be tiltedly disposed on the support base 110. Whether the frame portion is vertically disposed on the support base 110 or tiltedly disposed on the support base 110, it can work well and is also easy to operate.

[0031] The workpiece is mounted in the frame portion, so the workpiece can also be vertical or tilted relative to the support base 110. By placing the workpiece vertically or tilted, there is no need to perform vacuuming when laying it flat, and there is no need to worry about the problem of ink sucking out.

[0032] The angle of the frame portion relative to the support seat 110 is 30-90 degrees. That is, when the workpiece is installed, the angle between the frame portion and the support seat 110 can be 30-90 degrees for installation.

[0033] The workpiece is installed in the frame, and the angle of the frame relative to the support seat 110 is 30-90 degrees. When the workpiece is installed in the frame, the angle of the workpiece relative to the support seat is 30-90 degrees. That is, when the workpiece is installed, the angle between the workpiece and the support seat 110 is 30-90 degrees to ensure normal operation of the later exposure.

[0034] For example, the angle of the frame portion relative to the support base 110 may be 30 degrees, 45 degrees, 60 degrees, 75 degrees, or 90 degrees.

[0035] The shape of the through hole includes but is not limited to square, circular, and oval. In other words, in order to process different workpieces, through holes in shapes such as square, circular, and oval can be selected according to needs, so as to facilitate installation and placement. However, the present application is not limited thereto, and the through hole can also be a parallelogram or an irregular shape, which can be selected according to needs, and the present application does not limit it.

[0036] Among them, a through hole is provided on the frame part, so that the workpiece is placed from one side of the frame part for exposure through the through hole, and when the exposure is completed, the workpiece is taken out from the other side; while the workpiece is taken out, the next workpiece is put in from one side of the frame part in time, and the workpieces taken out and put in will not interfere with each other, which greatly improves the replacement efficiency and also improves the exposure efficiency.

[0037] Optionally, the number of through holes on the frame portion is greater than or equal to one, and each through hole can be corresponding to at least one workpiece. By providing at least one through hole on each frame portion, multiple workpieces can be exposed at the same time; and by providing at least one workpiece to be installed in each through hole, one or more workpieces can be installed in one through hole according to the size of the workpiece, thereby better realizing the utilization rate of the frame portion.

[0038] like Figure 1-Figure 3 As shown, in some embodiments, the device further includes a driving mechanism, which can drive the frame portion to move in the exposure scanning direction, and / or the driving mechanism can drive the exposure assembly 120 to move in the exposure scanning direction. In other words, the frame portion and / or the exposure assembly 120 can be driven; the frame portion is moved to the exposure area of ​​the exposure assembly 120 and / or the exposure assembly 120 is moved to the exposure area of ​​the exposure assembly 120 to ensure normal exposure.

[0039] like Figure 1-Figure 3 As shown, in an optional embodiment, only the frame portion is movable and the exposure component 120 is fixed, that is, the exposure component 120 is fixedly mounted on the support seat 110, and 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 component 120 for exposure, or moved out of the exposure area to pick up and place the workpiece.

[0040] like Figure 4 As shown, when both the frame part and the exposure component 120 are movable, that is, the frame part is driven by the driving mechanism to move along the exposure scanning direction, so that the workpiece is moved to a rough exposure area of ​​the exposure component 120, and then the driving mechanism will drive the exposure component to move again to make the workpiece accurately exposed, and then the driving mechanism drives the frame part to move out of the exposure area to pick up and place the workpiece.

[0041] In other embodiments, when the frame portion is fixed and the exposure component 120 is movable, that is, the frame portion is fixedly mounted on the support seat 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 facilitate the workpiece to be taken and placed.

[0042] like Figure 1-Figure 3 As shown, in this embodiment, the exposure assembly 120 includes a first exposure unit 121 and a second exposure unit 122; the first surface is close to the first exposure unit, and the second surface is close to the second exposure unit; the first exposure unit 121 can emit an exposure beam to the first surface, thereby exposing one side of the workpiece installed in the frame; the second exposure unit 122 can emit an exposure beam to the second surface, thereby exposing the other side of the workpiece installed in the frame. The first exposure unit 121 and the second exposure unit 122 are used to simultaneously expose the workpiece in the frame on both sides, without the need for flipping, and the double-sided exposure of the workpiece is completed at one time, saving the time consumed by flipping, and further improving the efficiency of exposure.

[0043] The number of frame parts is greater than or equal to two. Figure 1-Figure 4 In the embodiment, there are two frame parts, namely, a first frame part 130 and a second frame part 140. By using multiple frame parts, when a workpiece on one frame part is being exposed, another frame part can be used to take and place the workpiece, so that alternating operations can be performed without stopping the machine, thereby improving exposure efficiency.

[0044] like Figure 1-Figure 3As shown, taking the frame part including the first frame part 130 and the second frame part 140 as an example, the frame part includes the first frame part 130 and the second frame part 140; the first frame part 130 includes the first mounting part 132, and the second frame part 140 includes the second mounting part 142; the first frame part 130 and the second frame part 140 are arranged on the support seat 110, the first mounting part 132 is mounted in the first frame part 130, and the second mounting part 142 is mounted in the second frame part 140; the driving mechanism includes the first driving component and the second driving component; the first driving component is used to drive the first frame part 130 to move in the exposure scanning direction; the second driving component is used to drive the second frame part 140 to move in the exposure scanning direction. In other words, the first frame part 130 is moved in the exposure scanning direction by the first driving component, and the second frame part 140 is moved in the exposure scanning direction by the second driving component, and the exposure operation is performed through the two frames, which can save waiting time and speed up the exposure efficiency.

[0045] like Figure 1-Figure 3 As shown, in this embodiment, the device 100 further includes a first control unit, which is used to control the first driving component and the second driving component to drive the first frame 130 and the second frame 140 to move alternately. That is, when the first driving component drives the first frame 130 to move in the exposure scanning direction, the second driving component drives the second frame 140 to move away from the exposure scanning direction; similarly, when the first driving component drives the first frame 130 to move away from the exposure scanning direction, the second driving component drives the second frame 140 to move in the exposure scanning direction; and by driving the first frame 130 and the second frame 140 to move alternately by the first driving component and the second driving component, it can be ensured that at the same time, one workpiece is exposed and the other workpiece is replaced, which reduces the downtime of removing the workpiece and replacing the workpiece after exposure, and speeds up the exposure efficiency.

[0046] like Figure 1-Figure 3 As shown, in this embodiment, the first driving assembly includes a first track 151 and a first driving mechanism; the first track 151 is provided on the support seat 110; the first frame 130 is installed on the first track 151, and the first driving mechanism drives the first frame 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 provided on the support seat 110; the second frame 140 is installed on the second track 161, and the second driving mechanism drives the second frame 140 to move along the second track 161. The first frame 130 and the second frame 140 are moved by using the track, which effectively ensures the stability of the displacement of the first frame 130 and the second frame 140.

[0047] As an example, the first driving mechanism and the second driving mechanism may both include racks, gears, and a first motor. The first motor is respectively installed on the first frame portion 130 and the second frame portion 140, and the gear is installed on the first motor; the racks are respectively installed on the first track 151 and the second track 161, and the rotation of the first motor drives the first frame portion 130 and the second frame portion 140 to move along the track through the gear and the rack. Driving the first frame portion 130 and the second frame portion 140 to move in the form of a gear and a rack can effectively ensure the stability of the first frame portion 130 and the second frame portion 140. At the same time, in the form of a gear and a rack, it can stop after moving to an accurate position, ensuring the accuracy of exposure.

[0048] As Figure 1-Figure 3 shown, in some embodiments, the first track 151 and the second track 161 are located between the first exposure portion 121 and the second exposure portion 122.

[0049] However, the present application is not limited to the parallel implementation manner. For example, the first track 151 and the second track 161 are parallel to the tracks within the exposure ranges of the first exposure portion 121 and the second exposure portion 122, but the distance between the first track 151 and the second track 161 that is not within the exposure ranges of the first exposure portion 121 and the second exposure portion 122 gradually increases or gradually decreases.

[0050] Different track setting methods can be configured according to the specific situation of the device, and the present application does not make any restrictions.

[0051] As Figure 1-Figure 3 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 portion 121 to approach or move away from the first track 151; the fourth driving mechanism is used to drive the second exposure portion 122 to approach or move away from the second track 161. By using the third driving mechanism to drive the first exposure portion 121 to move and the fourth driving mechanism to drive the second exposure portion 122 to move, the distance between the workpiece and the two exposure portions is adjusted, ensuring the accuracy of exposure.

[0052] As Figure 1-Figure 3 shown, in this embodiment, the device further includes a second control unit; the second control unit controls the movement of the third driving mechanism and the fourth driving 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 installed on the first frame portion 130 or the second frame portion 140 is located in the exposure areas 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 through the second control unit, the workpiece is placed in the area to be exposed, ensuring the accuracy of exposure.

[0053] As Figure 1-Figure 3As shown, in this embodiment, the first frame 130 includes a first frame 131 and a first mounting portion 132; the second frame 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 in the first frame 131; the workpiece can be mounted on the first mounting portion 132 through one side or the other side of the first frame 131, and the workpiece can be taken out from the first mounting portion 132 through 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 in the second frame 141; the workpiece is mounted on the second mounting portion 142 through one side or the other side of the second frame 141, and the workpiece is taken out from the second mounting portion 142 through one side or the other side of the second frame 141. The frame structure can support the workpiece and prevent deviation in exposure; through the design of the mounting portion, the workpiece can be effectively exposed on both sides.

[0054] like Figure 1-Figure 3 As shown, in some embodiments, the first mounting portion 132 and the second mounting portion 142 of the frame portion both 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. In other words, the workpiece is first fixed by the fixing member 1a and the clamping member 1b, and then the traction mechanism 1c moves to drive the clamping member 1b to ensure the flatness of the workpiece and prevent the workpiece from bending due to non-flattening and affecting the exposure accuracy; at the same time, after tightening the two sides, the traction mechanism c1 tightens the workpiece, and no longer uses the compression and vacuuming method to maintain the flatness, which can prevent the problem of ink being sucked out due to vacuuming.

[0055] 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 thereof, 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 the first electromagnet 1a3; when a forward current is passed through the first electromagnet 1a3, the first permanent magnet 1a2 and the first electromagnet 1a3 attract each other, so that the workpiece can be fixed and clamped; when a reverse current is passed through, the first permanent magnet 1a2 and the first electromagnet 1a3 repel each other, and the workpiece can be removed. The clamping member 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 respectively mounted on the other side of the first frame 131 and the second frame 141, 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 passed through the second electromagnet 1b4, the second permanent magnet 1b3 and the second electromagnet 1b4 attract each other, so that the workpiece can be clamped and fixed; when a reverse current is passed through, the second permanent magnet 1b3 and the second electromagnet 1b4 repel each other, and the workpiece can be removed. Through the coordinated use of electromagnets and permanent magnets, the clamping or separation of the workpiece can be quickly achieved.

[0056] 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 respectively located on the side of the first frame 131 and the second frame 141 close to the clamping member 1b; the conveyor belt 1c13 and the sliding rod 1c14 are respectively located on both sides of the clamping member 1b; the two sides of the clamping member 1b are installed on the sliding rod 1c14, the second motor 1c11 drives the rotating shaft 1c12 to rotate, the rotating shaft 1c12 drives the conveyor belt 1c13 to rotate, and the conveyor belt 1c13 drives the clamping member 1b to move along the sliding rod 1c14, so that the clamping member 1b is close to or away from the fixed member 1a. The use of the conveyor belt 1c13 to drive the clamping part to move can ensure the flatness of the workpiece, thereby ensuring the exposure accuracy of the workpiece.

[0057] 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 rods 1c23 are respectively located on both sides of the clamping member 1b; the two sides of the clamping member 1b are installed on the guide rods 1c23, the tension spring 1c22 is sleeved on the guide rods 1c23, the lower end of the tension spring 1c22 is fixed to the clamping member 1b, the tension spring 1c22 gives the clamping member 1b an upward force, so that the clamping member 1b can move upward, and is stretched and fixed to the lower side of the clamping member 1b, and the third motor 1c21 is installed on the lower side of the frame part, and the rotation of the third motor 1c21 can drive the stretching and retraction. That is, the pull rope 1c24 is pulled down by the motor, and then the clamping member 1b is moved downward, and the workpiece fixed on the clamping member 1b is tightened, which can ensure the flatness of the workpiece, and then ensure the exposure accuracy of the workpiece.

[0058] In another embodiment, the first mounting portion 132 and the second mounting portion 142 of the frame portion both 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 to move in a direction 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 toward the side away from the fixing member, so that the workpiece is flattened, and the exposure accuracy is prevented from being bent due to the unflattened workpiece; 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.

[0059] like Figure 1-Figure 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 130 or the second frame 140, the positioning component 170 can position the workpiece; a target point is provided on the workpiece. When the workpiece passes through the positioning component 170, the positioning component 170 will identify the target point on the workpiece, determine the precise exposure position according to the target point, and then feed back to the exposure component 120, so that the exposure component 120 can accurately expose the workpiece, thereby ensuring the accuracy of the exposure.

[0060] The workpiece is a circuit board, which includes a PCB board, an FPC board, etc.

[0061] The first motor, the second motor 1c11 and the third motor 1c21 are all three-phase asynchronous motors.

[0062] Figure 3The second pick-and-place mechanism 220 takes out the workpiece from the second surface of the frame, and the first pick-and-place mechanism 210 installs the workpiece from the first surface of the frame. In other words, by having the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 located on both sides of the frame, the workpiece can be taken out from one side while being put in from the other side, thereby achieving compact coordination, saving time when installation and pick-and-place are performed separately, speeding up replacement efficiency, and ensuring that it is always ready for exposure.

[0063] However, the present application is not limited thereto, and the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 may be located on the same side of the frame portion to pick and place the workpiece on the same side.

[0064] In some embodiments, the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 are manipulators, which can be installed on the support base 110 with the movable ends of the manipulators facing upward.

[0065] Figure 3 The middle robot is installed on the surface of the support base, but the present application is not limited to this. The robot can also be set above the support base 110 so that the movable end of the robot faces downward.

[0066] The manipulator may be a part of the digital exposure LDI device, or may be a manipulator on a robot independent of the digital exposure LDI device, and this application does not impose any limitation thereto.

[0067] If the first pick-and-place mechanism 210 is responsible for taking out 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 clamps the workpiece, it first moves away from the support seat, such as upward, so that the workpiece does not collide with the frame portion when rotating, and then rotates the workpiece from a vertical state to a horizontal state, placing the workpiece horizontally in the placement area. Then, after the first pick-and-place mechanism 210 takes out the workpiece, the second pick-and-place mechanism 220 can install the next workpiece in the frame portion and move it out after installation.

[0068] In summary, the present invention provides a vertical digital exposure LDI device and exposure system that are easy to take and place circuit boards. By placing the workpiece in the through hole on the vertical frame part, the workpiece is made upright, and there is no need to lay the workpiece flat. 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 the flatness of the workpiece, resulting in poor exposure effect.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements 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 the present application.
