Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of high-end equipment manufacturing, and in particular to a vertical left-right exchange frame digital exposure LDI device for a circuit board and an exposure system. 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: First, 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] Second, 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] Third, the circuit board is placed on the working frame, and the circuit board is in direct contact with the adsorption panel on the working 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.

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.
[0026] 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.

[0027] like Figure 1-Figure 4As shown, this embodiment provides a circuit board vertical left-right exchange frame digital exposure LDI device 100, which includes a support seat 110, an exposure assembly 120, a first frame portion 130, a second frame portion 140, and a driving assembly. The exposure assembly 120 is arranged on the support seat 110, and is used to expose the workpiece; the first frame portion 130 is arranged upright on the support seat 110, and is used to install the workpiece and make the workpiece stand upright; the second frame portion 140 is arranged upright on the support seat 110, and is used to install the workpiece and make the workpiece stand upright; the driving 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. That is to say, by placing the first frame portion 130 and the second frame portion 140 upright on the support seat 110, the lateral space occupied by the digital lithography LDI device 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 be exposed alternately, which can save the waiting time for installation and improve the exposure efficiency; by placing the first frame portion 130 and the second frame portion 140 upright on the support seat 110, the workpiece is also 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; in addition, it can also solve the problem that dust is easily trapped on the exposure lens on the lower side when laying flat for double-sided exposure, thereby affecting the effect of later exposure.
[0028] like Figure 1-Figure 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, the exposure component 120 is fixedly mounted on the support seat 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 to take and place the workpiece.
[0029] 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 rough exposure area of the exposure component 120, and then the driving component will drive the exposure component 120 to move again to make the workpiece accurately exposed, and then the driving component drives the frame portion to move out of the exposure area to pick up and place the workpiece.
[0030] 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, the first frame portion 130 and the second frame portion 140 are fixedly mounted on the support seat 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 facilitate the workpiece to be taken and placed.
[0031] 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 exposure unit 121 and the second exposure unit 122 are located on both sides of the first frame 130 and the second frame 140, and the first exposure unit 121 and the second exposure unit 122 can be used to perform double-sided exposure on the workpiece installed in the first frame 130 or the second frame 140. The first exposure unit 121 and the second exposure unit 122 are used to perform double-sided exposure on the workpiece in the first frame 130 or the second frame 140 at the same time, without the need for flipping, and the double-sided exposure of the workpiece is completed at one time, which saves the time consumed by flipping and further improves the efficiency of exposure.
[0032] like Figure 1-Figure 3 As shown, in this embodiment, both the first frame 130 and the second frame 140 include through holes penetrating the first surface and the second surface thereof; the first surface is close to the first exposure section 121, and the second surface is close to the second exposure section 122; the first exposure section 121 can emit an exposure beam to the first surface, thereby exposing one side of the workpiece installed in the first frame 130 or the second frame 140; the second exposure section 122 can emit an exposure beam to the second surface, thereby exposing the other side of the workpiece installed in the first frame 130 or the second frame 140. The first exposure section 121 and the second exposure section 122 are used to simultaneously perform double-sided exposure on the workpiece in the first frame 130 or the second frame 140, 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.
[0033] like Figure 1-Figure 3 As shown, in some embodiments, the first frame portion 130 is disposed perpendicular to the support seat 110 for mounting a workpiece and making the workpiece perpendicular to the support seat 110; the second frame portion 140 is disposed perpendicular to the support seat 110 for mounting a workpiece and making the workpiece perpendicular to the support seat 110.
[0034] In other embodiments, the first frame portion 130 is arranged to be inclined relative to the support seat 110 for mounting a workpiece and tilting the workpiece relative to the support seat 110 ; the second frame portion 140 is arranged to be inclined relative to the support seat 110 for mounting a workpiece and tilting the workpiece relative to the support seat 110 .
[0035] Whether the first frame 130 and the second frame 140 are perpendicular to the support base 110 or tilted relative to the support base 110 , compared with horizontal placement, both can improve exposure efficiency, eliminate the need for vacuum adsorption, and ensure exposure effects.
[0036] When the workpiece is mounted on the frame, the workpiece is perpendicular to the support seat 110 or the workpiece is inclined relative to the support seat 110. By placing the workpiece vertically or obliquely, there is no need to perform vacuuming when placing it flat, and there is no need to worry about the problem of ink suction.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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 workpiece. By providing at least one through hole on each frame portion, the workpiece in at least one through hole on a frame portion can be exposed according to the exposure range of the exposure assembly 120, thereby better realizing the utilization rate of the exposure assembly 120; and by installing at least one workpiece in each through hole, one or more workpieces can be installed in a through hole according to the size of the workpiece, thereby better realizing the utilization rate of the frame portion.
[0041] The number of frame parts is greater than or equal to two, e.g. 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.
[0042] like Figure 1-Figure 3 As 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 component 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.
[0043] 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 another workpiece is replaced, which reduces the downtime of removing the workpiece and replacing the workpiece after exposure, and speeds up the exposure efficiency.
[0044] like Figure 1-Figure 3 As shown, in this embodiment, the first driving assembly includes a first track 151 and a first driving assembly; 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 assembly 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 assembly; 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 assembly 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.
[0045] As an example, the first driving assembly and the second driving assembly both include a rack, a gear, and a first motor. The first motor is mounted on the first frame 130 and the second frame 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, and the first motor rotates to drive the first frame 130 and the second frame 140 to move along the track through the gear and the rack. The use of a rack and gear to drive the first frame 130 and the second frame 140 to move can effectively ensure the stability of the first frame 130 and the second frame 140. At the same time, the use of a rack and gear can move to an accurate position and then stop, thereby ensuring the accuracy of exposure.
[0046] like Figure 1-Figure 3 As 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 .
[0047] However, the present application is not limited to parallel implementations. For example, the first track 151 and the second track 161 are parallel to the tracks within the exposure range of the first exposure section 121 and the second exposure section 122, but the spacing between the first track 151 and the second track 161 that are not within the exposure range of the first exposure section 121 and the second exposure section 122 gradually increases or decreases.
[0048] Different track settings can be configured according to the specific circumstances of the device, and this application does not impose any restrictions.
[0049] like Figure 1-Figure 3 As shown, in this embodiment, the device 100 further includes a third driving assembly and a fourth driving assembly; the third driving assembly is used to drive the first exposure unit 121 to approach or move away from the first track 151; the fourth driving assembly is used to drive the second exposure unit 122 to approach or move away from the second track 161. The third driving assembly is used to drive the first exposure unit 121 to move, and the fourth driving assembly is used to drive the second exposure unit 122 to move, so as to adjust the distance between the workpiece and the two exposure units to ensure the accuracy of exposure.
[0050] like Figure 1-Figure 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 assembly and the fourth driving assembly; when the first frame 130 moves to the exposure range of the exposure assembly 120, the second control unit controls the first exposure unit 121 and / or the second exposure unit 122 to move, so that the workpiece mounted on the first frame 130 or the second frame 140 is located in the exposure area of the first exposure unit 121 and the second exposure unit 122. The second control unit controls the movement of the first exposure unit 121 and / or the second exposure unit 122 to place the workpiece in the area to be exposed, thereby ensuring the accuracy of exposure.
[0051] like 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.
[0052] like Figure 4 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 both sides, the traction mechanism 1c 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.
[0053] 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, so that 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.
[0054] 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.
[0055] 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. 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 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. 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 workpiece is prevented from bending due to non-flattening and affecting 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.
[0056] like Figure 1-Figure 3 As shown, in this embodiment, the device 100 further includes a positioning assembly 170; when the workpiece moves toward the exposure assembly 120 along with the first frame 130 or the second frame 140, the positioning assembly 170 can position the workpiece; a target point is provided on the workpiece. When the workpiece passes through the positioning assembly 170, the positioning assembly 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 assembly 120, so that the exposure assembly 120 can accurately expose the workpiece, thereby ensuring the accuracy of the exposure.
[0057] The workpiece is a circuit board, which includes a PCB board, an FPC board, etc.
[0058] 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 to install the workpiece in the frame part; the second pick-and-place mechanism 220 is used to take out the workpiece in the frame part.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] 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.
[0064] 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 moving upward, so that the workpiece will not collide with the frame portion when rotating, and then rotates the workpiece from a vertical state to a horizontal state, and places 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, so that the pick-and-place interval is short and the exposure efficiency is high.
[0065] In summary, the present invention provides a circuit board vertical left-right exchange frame digital exposure LDI device and exposure system. By placing the workpiece in a vertical first frame portion or a second frame portion, the workpiece is made to stand 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.
[0066] 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.
