Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-end equipment manufacturing technology, in particular to a vertical left-right exchange frame digital exposure LDI equipment for circuit board and an exposure system. BACKGROUND

[0002] The current industry digital exposure LDI equipment is realized by single-side exposure, that is, the circuit board is placed on the working frame of the LDI equipment, the board is sucked flat and fixed on the working frame by vacuumizing and pressing the edge of the circuit board, and scanning exposure is performed to complete the exposure of the first side. Then, the circuit board is turned over manually or by an automatic board turning device, and placed on the working frame of the LDI equipment, the board is sucked flat and fixed on the working frame by vacuumizing 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 problems that cannot be solved:

[0003] First, the circuit board is placed on the working frame, and needs to be sucked flat on the working frame by vacuumizing from the bottom, but some double-sided multi-layer boards have many holes, the inside of the hole is protected by ink plugging, and vacuumizing from the bottom will suck out the ink in the hole, causing plugging oil leakage.

[0004] Second, based on the problem in the first point, many equipment manufacturers control the vacuum pump or air blower by increasing the frequency converter to reduce the vacuum degree, and combine the four-edge pressing plate to prevent the ink in the hole from being sucked out when vacuumizing, but the suction force is reduced after the vacuum degree is reduced, and the circuit board cannot be sucked flat on the working frame, causing poor exposure effect.

[0005] 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, causing copper leakage and exposure defects. In addition, in order to reduce the occurrence of this problem, the adsorption panel needs to be treated with high-level anti-sticking. This high-level anti-sticking treatment has high cost and can only maintain for two to three months, greatly increasing the hardware cost. Even so, it cannot completely solve the problem of copper leakage and exposure defects.

[0006] Fourth, the circuit board is placed horizontally, and the exposure assembly needs to be placed vertically, the lens on the lower group of exposure assemblies needs to be directed upward to expose the circuit board, the lens on the lens is easy to fall dust and be polluted, causing poor exposure effect, and the lower group of exposure assemblies is difficult to debug and maintain.

[0007] Fifth, in order to meet the exposure requirements, the circuit board needs to be kept in a flat state. If a tensioning device is used to pull the circuit board flat, the circuit board cannot be effectively pulled flat in the horizontal direction due to the action of gravity. SUMMARY

[0064] AsFigures 1-4 As shown, the embodiment provides a circuit board vertical left-right exchange frame digital exposure LDI equipment 100, which comprises a support seat 110, an exposure assembly 120, a first frame part 130, a second frame part 140, and a driving assembly. The exposure assembly 120 is arranged on the support seat 110 and is used for exposing a workpiece; the first frame part 130 is arranged vertically on the support seat 110 and is used for mounting the workpiece and making the workpiece vertical; the second frame part 140 is arranged vertically on the support seat 110 and is used for mounting the workpiece and making the workpiece vertical; the driving assembly is used for driving the first frame part 130 and the second frame part 140 to move in an exposure scanning direction; and / or driving the exposure assembly 120 to move in the exposure scanning direction. That is, the first frame part 130 and the second frame part 140 are arranged vertically on the support seat 110, which can reduce the horizontal space occupied by the digital light etching LDI equipment 100; the driving assembly is used for driving the first frame part 130 and the second frame part 140 to move in the exposure scanning direction; and / or driving the exposure assembly 120 to move in the exposure scanning direction, which can make the two frame parts alternately perform exposure operation, save the waiting time for installation, and improve the exposure efficiency; the first frame part 130 and the second frame part 140 are arranged vertically on the support seat 110, which makes the workpiece vertical, so that the workpiece does not need to be placed horizontally, and the problem that the ink on the workpiece is sucked out when the workpiece is placed horizontally to ensure the flatness of the workpiece, resulting in poor exposure effect, can be solved; in addition, the problem that dust is easily fallen on the exposure lens on the lower side when double-sided exposure is performed in a horizontal manner, resulting in affecting the exposure effect in the later period, can also be solved.

[0065] As shown in the embodiment, when the first frame part 130 and the second frame part 140 are movable and the exposure assembly 120 is fixed, that is, the exposure assembly 120 is fixedly mounted on the support seat 110, the first frame part 130 or the second frame part 140 is driven by the driving assembly to move in the exposure scanning direction, so that the workpiece is moved to the exposure area of the exposure assembly 120 for exposure or is moved out of the exposure area for taking and placing the workpiece. Figures 1-3 As shown in the embodiment, when the first frame part 130, the second frame part 140, and the exposure assembly 120 are movable, that is, the first frame part 130 or the second frame part 140 is driven by the driving assembly to move in the exposure scanning direction, so that the workpiece is moved to a substantially exposure area of the exposure assembly 120, then the driving assembly drives the exposure assembly 120 to move again, so that the workpiece is accurately exposed, and then the driving assembly drives the frame part to move out of the exposure area for taking and placing the workpiece.

[0066] Figure 4 As shown in the embodiment, when the first frame part 130, the second frame part 140, and the exposure assembly 120 are movable, that is, the first frame part 130 or the second frame part 140 is driven by the driving assembly to move in the exposure scanning direction, so that the workpiece is moved to a substantially exposure area of the exposure assembly 120, then the driving assembly drives the exposure assembly 120 to move again, so that the workpiece is accurately exposed, and then the driving assembly drives the frame part to move out of the exposure area for taking and placing the workpiece.

[0067] ​In other embodiments, when the first frame 130 and the second frame 140 are fixed, the exposure assembly 120 is movable, that is, the first frame 130 and the second frame 140 are fixedly installed on the support base 110, and the exposure assembly 120 is driven by the driving assembly to move along the exposure scanning direction, so that the exposure assembly 120 moves to the exposure area of the workpiece to expose the workpiece, or the exposure assembly 120 moves out of the exposure area to facilitate the taking and placing of the workpiece.

[0068] As shown in the drawings, Figures 1-3 In the present embodiment, the exposure assembly 120 includes a first exposure part 121 and a second exposure part 122; the first exposure part 121 and the second exposure part 122 are located on both sides of the first frame 130 and the second frame 140, and the first exposure part 121 and the second exposure part 122 can be used for double-sided exposure of the workpiece installed in the first frame 130 or the second frame 140. By using the first exposure part 121 and the second exposure part 122 to simultaneously perform double-sided exposure on the workpiece in the first frame 130 or the second frame 140, the workpiece does not need to be flipped again, and the double-sided exposure of the workpiece is completed at one time, thereby saving the time consumed by flipping and further accelerating the exposure efficiency.

[0069] As shown in the drawings, Figures 1-3 In the present embodiment, the first frame 130 and the second frame 140 each include a through hole penetrating through a first surface and a second surface thereof; the first surface is close to the first exposure part 121, and the second surface is close to the second exposure part 122; the first exposure part 121 can emit an exposure light beam to the first surface, thereby exposing one side of the workpiece installed in the first frame 130 or the second frame 140; and the second exposure part 122 can emit an exposure light beam to the second surface, thereby exposing the other side of the workpiece installed in the first frame 130 or the second frame 140. By using the first exposure part 121 and the second exposure part 122 to simultaneously perform double-sided exposure on the workpiece in the first frame 130 or the second frame 140, the workpiece does not need to be flipped again, and the double-sided exposure of the workpiece is completed at one time, thereby saving the time consumed by flipping and further accelerating the exposure efficiency.

[0070] As shown in the drawings, Figures 1-3 In some embodiments, the first frame 130 is arranged perpendicularly to the support base 110, for installing the workpiece and making the workpiece perpendicular to the support base 110; and the second frame 140 is arranged perpendicularly to the support base 110, for installing the workpiece and making the workpiece perpendicular to the support base 110.

[0071] In some other embodiments, the first frame portion 130 is arranged to be inclined to the support base 110, for mounting the workpiece and making the workpiece inclined to the support base 110; and the second frame portion 140 is arranged to be inclined to the support base 110, for mounting the workpiece and making the workpiece inclined to the support base 110.

[0072] The first frame portion 130 and the second frame portion 140 are arranged to be perpendicular to the support base 110 or inclined to the support base 110, which can improve the exposure efficiency compared with horizontal placement, and no vacuum suction is needed to ensure the exposure effect.

[0073] When the workpiece is mounted in the frame portion, the workpiece is perpendicular to the support base 110 or the workpiece is inclined to the support base 110. By vertically or obliquely placing the workpiece, no vacuum suction operation is needed when the workpiece is placed horizontally, and there is no need to worry about the problem of ink suction.

[0074] When the workpiece is mounted in the frame portion, the angle between the workpiece and the support base 110 is 30-90 degrees. That is, when the workpiece is mounted, the angle between the workpiece and the support base 110 is 30-90 degrees, which ensures the normal operation of the later exposure.

[0075] Exemplarily, the angle between the frame portion and the support base 110 can be 30 degrees or 45 degrees or 60 degrees or 75 degrees or 90 degrees.

[0076] The shape of the through hole includes but is not limited to square, circular, and oval. That is, in order to process different workpieces, square, circular, oval, etc. The shape of the through hole can be selected according to the needs to facilitate installation and taking. 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 as needed, and the present application does not make any limitation.

[0077] The number of through holes on the frame portion is greater than or equal to one, and each through hole can correspond to the mounting of at least one workpiece. By providing not less than one through hole on each frame portion, the workpieces in the not less than one through holes on one frame portion can be exposed according to the exposure range of the exposure assembly 120, and the utilization rate of the exposure assembly 120 can be better realized. By mounting not less than one workpiece in each through hole, one or more workpieces can be installed in one through hole according to the size of the workpiece, and the utilization rate of the frame portion can be better realized.

[0078] The number of frame portions is greater than or equal to two, for example Figures 1-4 In the embodiment, the number of frame portions is two, which are the first frame portion 130 and the second frame portion 140. By using multiple frame portions, the workpieces on one frame portion can be exposed, and the other frame portions can be used for taking and placing workpieces; the alternating operation can be carried out without stopping, and the exposure efficiency can be improved.

[0079] As shown in Figures 1-3 In the embodiment, the frame portion includes a first frame portion 130 and a second frame portion 140; the first frame portion 130 includes a first mounting portion 132, and the second frame portion 140 includes a second mounting portion 142; the first frame portion 130 and the second frame portion 140 are arranged on the support base 110; the first mounting portion 132 is mounted in the first frame portion 130, and the second mounting portion 142 is mounted in the second frame portion 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 portion 130 to move in the exposure scanning direction; and the second driving assembly is used to drive the second frame portion 140 to move in the exposure scanning direction. That is, the first frame portion 130 moves in the exposure scanning direction through the first driving assembly, and the second frame portion 140 moves in the exposure scanning direction through the second driving assembly, so that the exposure operation is performed through the two frame portions, the waiting time is saved, and the exposure efficiency is improved.

[0080] In the embodiment, the device 100 further includes a first control unit, which is used to control the first driving assembly and the second driving assembly to drive the first frame portion 130 and the second frame portion 140 to move alternately. That is, when the first driving assembly drives the first frame portion 130 to move in the exposure scanning direction, the second driving assembly drives the second frame portion 140 to move away from the exposure scanning direction; similarly, when the first driving assembly drives the first frame portion 130 to move away from the exposure scanning direction, the second driving assembly drives the second frame portion 140 to move in the exposure scanning direction; and through the first driving assembly and the second driving assembly, the first frame portion 130 and the second frame portion 140 are driven to move alternately, so that one workpiece is exposed and another workpiece is replaced at the same time, the downtime of removing the workpiece after exposure and replacing the workpiece is reduced, and the exposure efficiency is improved.

[0081] As shown in Figures 1-3 In the embodiment, the first driving assembly includes a first track 151 and a first driving assembly; the first track 151 is arranged on the support base 110; the first frame portion 130 is mounted on the first track 151, and the first driving assembly drives the first frame portion 130 to move along the first track 151; the second driving assembly includes a second track 161 and a second driving assembly; the second track 161 is arranged on the support base 110; the second frame portion 140 is mounted on the second track 161, and the second driving assembly drives the second frame portion 140 to move along the second track 161. The first frame portion 130 and the second frame portion 140 move in the track mode, so that the stability of displacement of the first frame portion 130 and the second frame portion 140 is effectively ensured.

[0082] As an example, the first driving assembly and the second driving assembly each 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 rack and the gear are used to drive the first frame 130 and the second frame 140 to move, which can effectively ensure the stability of the first frame 130 and the second frame 140. At the same time, the rack and the gear can stop at an accurate position after moving, which ensures the accuracy of exposure.

[0083] As shown in FIG. 1, Figures 1-3 In some embodiments, the first track 151 and the second track 161 are located between the first exposure part 121 and the second exposure part 122.

[0084] However, the present application is not limited to parallel embodiments. For example, the first track 151 and the second track 161 are parallel to the tracks in the exposure range of the first exposure part 121 and the second exposure part 122, but the distance between the first track 151 and the second track 161 gradually increases or gradually decreases between the tracks in the exposure range of the first exposure part 121 and the second exposure part 122.

[0085] Different track arrangement modes can be used according to the specific conditions of the device, and the present application does not make any limitation.

[0086] As shown in FIG. 1, Figures 1-3 In the present 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 part 121 to move close to or away from the first track 151. The fourth driving assembly is used to drive the second exposure part 122 to move close to or away from the second track 161. The third driving assembly is used to drive the first exposure part 121 to move, and the fourth driving assembly is used to drive the second exposure part 122 to move, so as to adjust the distance between the workpiece and the two exposure parts and ensure the accuracy of exposure.

[0087] As shown in FIG. 1, Figures 1-3 In the present embodiment, the device further includes a second control unit. The second control unit controls the third driving assembly and the fourth driving assembly to move. When the first frame 130 moves into the exposure range of the exposure assembly 120, the second control unit controls the first exposure part 121 and / or the second exposure part 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 part 121 and the second exposure part 122. The second control unit controls the first exposure part 121 and / or the second exposure part 122 to move, so that the workpiece is located in the exposure area, which ensures the accuracy of exposure.

[0088] As shown in FIG. 1, 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.

[0089] 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 on 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.

[0090] like Figure 7As shown, in some embodiments, the fixing part 1a includes a first pressing plate 1a1, a first permanent magnet and a first electromagnet 1a3; the first frame 131 and the second frame 141 each include the first pressing plate 1a1 arranged on one side thereof, and the first permanent magnet is mounted on the first pressing plate 1a1; the first electromagnet 1a3 is mounted on the first frame 131 and the second frame 141 respectively; when the first electromagnet 1a3 is supplied with a forward current, the first permanent magnet 1a2 and the first electromagnet 1a3 are attracted to each other, so that the workpiece can be fixed and clamped; when a reverse current is supplied, the first permanent magnet 1a2 and the first electromagnet 1a3 are repelled to each other, and the workpiece can be removed. The clamping part 1b includes a support plate 1b1, a second pressing 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 pressing plate 1b2 is mounted on the support plate 1b1, and the second permanent magnet is mounted on the second pressing plate 1b2; the second electromagnet 1b4 is mounted on the support plate 1b1; when the second electromagnet 1b4 is supplied with a forward current, the second permanent magnet 1b3 and the second electromagnet 1b4 are attracted to each other, so that the workpiece can be clamped and fixed; when a reverse current is supplied, the second permanent magnet 1b3 and the second electromagnet 1b4 are repelled to each other, and the workpiece can be removed. Through the cooperation of the electromagnet and the permanent magnet, the clamping or separation of the workpiece can be quickly realized.

[0091] As shown, Figure 6 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 side of the first frame 131 and the second frame 141 close to the clamping part 1b respectively; the conveyor belt 1c13 and the sliding rod 1c14 are located on the two sides of the clamping part 1b respectively; the two sides of the clamping part 1b are mounted 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 part 1b to move along the sliding rod 1c14, so that the clamping part 1b approaches or moves away from the fixing part 1a. And the use of the conveyor belt 1c13 to drive the clamping part to move can ensure the flatness of the workpiece, and further ensure the exposure accuracy of the workpiece.

[0092] As shown, 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 piece 1b; the clamping piece 1b is installed on the guide rod 1c23, the tension spring 1c22 is sleeved on the guide rod 1c23, the lower end of the tension spring 1c22 is fixed with the clamping piece 1b, and the tension spring 1c22 provides an upward force to the clamping piece 1b, so that the clamping piece 1b can move upward, and the clamping piece 1b is stretched on the lower side; the third motor 1c21 is installed on the lower side of the frame, and the rotation of the third motor 1c21 can drive the stretching and retracting. That is, the pull rope 1c24 is pulled down by the motor, and then the clamping piece 1b moves downward, so that the workpiece fixed on the clamping piece 1b is tensioned, which can ensure the flatness of the workpiece and the exposure accuracy of the workpiece.

[0093] In another embodiment, the first mounting portion 132 and the second mounting portion 142 of the frame each include a fixing piece and a tension mechanism 1d; the fixing piece is used to fix one side of the workpiece; and the tension mechanism 1d is used to fix the other side of the workpiece and pull the other side of the workpiece away from the fixing piece. That is, after one side of the workpiece is fixed by the fixing piece, the other side of the workpiece is fixed by the tension mechanism 1d and pulled away from the fixing piece, so that the workpiece is flattened, preventing the workpiece from being bent due to not being flattened, which affects the exposure accuracy; at the same time, the workpiece is fixed on one side and tensioned on the other side, and the way of pressing and vacuumizing is no longer used to maintain the flatness, which can prevent the problem of ink suction caused by vacuumizing.

[0094] As shown, Figures 1-3 In this embodiment, the device 100 further includes a positioning assembly 170; when the workpiece moves towards the exposure assembly 120 with the first frame 130 or the second frame 140, the positioning assembly 170 can position the workpiece; and the workpiece is provided with a target point. When the workpiece passes through the positioning assembly 170, the positioning assembly 170 can identify the target point on the workpiece, determine the accurate position of exposure 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 exposure accuracy.

[0095] The workpiece is a circuit board, which includes a PCB board, an FPC board, etc.

[0096] As shown, Figure 3 This embodiment includes an exposure system, which includes 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 the workpiece in the frame; and the second pick-and-place mechanism 220 is used for taking out the workpiece in the frame.

[0097] Figure 3The second pick-and-place mechanism 220 picks 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. That is, by locating the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 on two sides of the frame, the workpiece can be picked up on one side while being placed on the other side, achieving compact cooperation, saving time when installing and picking up separately, accelerating the replacement efficiency, and ensuring that the exposure is always ready.

[0098] However, the present application is not limited thereto, and 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, and the workpiece is picked and placed on the same side.

[0099] In some embodiments, the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 are mechanical hands, which can be installed on the support seat 110, so that the movable end of the mechanical hand faces upward.

[0100] Figure 3 Figure 3 In some embodiments, the first pick-and-place mechanism 210 and the second pick-and-place mechanism 220 are mechanical hands, which can be installed on the support seat 110, so that the movable end of the mechanical hand faces upward.

[0101] The mechanical hand can be part of the digital exposure LDI device, or it can be a mechanical hand on a robot independent of the digital exposure LDI device, and the present application does not make any limitation.

[0102] If the first pick-and-place mechanism 210 is responsible for picking up the workpiece, and the second pick-and-place mechanism 220 is used to install the workpiece, then after the first pick-and-place mechanism 210 picks up the workpiece, it first moves away from the support seat, for example, moves upward, so that the workpiece does not collide with the frame when rotating, and then rotates the workpiece from the vertical state to the horizontal state, and places the workpiece horizontally in the placement area. Then, after the first pick-and-place mechanism 210 picks up the workpiece, the second pick-and-place mechanism 220 can install the next workpiece in the frame, and then move out after installation is completed, so that the interval between picking and placing is short, and the exposure efficiency is high.

[0103] In summary, the present application provides a vertical left-right exchange frame digital exposure LDI device and an exposure system, by placing the workpiece in the vertical first frame or the second frame, the workpiece is also vertical, so there is no need to place the workpiece horizontally, and there is no need to worry about the problem that the ink on the workpiece is sucked out when the workpiece is placed horizontally and vacuumized to ensure the flatness of the workpiece, resulting in poor exposure effect.

[0104] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art will understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent replacements for some of the technical features; and 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.
