Description

Technical Field

[0001] This utility model relates to the field of exposure machine technology, specifically to a vertical exposure machine. Background Technology

[0002] Currently, most digital exposure (LDI) equipment in the industry uses a single-sided exposure method. This involves placing the circuit board on the LDI equipment's work frame, flattening and fixing it to the frame using vacuuming and edge pressing, and then scanning to expose the first side. Then, a manual or automated flipping device flips the circuit board, places it back on the LDI equipment's work frame, and flattens and fixes it again using vacuuming and edge pressing, performing scanning exposure to complete the second side. This method of horizontally placing the circuit board has the following unresolved problems: To meet the exposure requirements, the circuit board needs to be kept flat. However, after the circuit board is installed, the actual condition of the workpiece can only be observed manually. This manual observation method makes it difficult to ensure the accuracy of the installation position and the accuracy of other parameters, resulting in poor subsequent exposure effects.

[0008] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0009] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0010] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0011] like Figures 1-2As shown, this embodiment provides a vertical exposure machine 1, comprising a support base 10, an exposure mechanism 30, a frame 20, a positioning component 91, and a workpiece detection mechanism 90. The exposure mechanism 30 is mounted on the support base 10 and is used to expose the workpiece; the frame 20 is erected on the support base 10 and is used to mount the workpiece; the positioning component 91 is used to identify target points on the workpiece and obtain target point data, which is used to calibrate the exposure mechanism 30; the workpiece detection mechanism 90 is used to detect the workpiece parameters of the workpiece mounted on the frame 20. By using the workpiece detection mechanism 90 to detect the workpiece parameters, the workpiece can be detected and analyzed before exposure, ensuring that the exposure accuracy is not affected by workpiece errors, thus ensuring the quality of the exposed workpiece.

[0012] like Figure 2 As shown, optionally, the workpiece inspection mechanism 90 includes a flatness inspection device 92; the flatness inspection device 92 is used to inspect the flatness of the workpiece. By using the flatness inspection device 92 to inspect the flatness, bends that may not have been observed in time can be detected, thus improving exposure accuracy.

[0013] like Figure 2 As shown, optionally, the flatness detection device 92 includes a laser rangefinder 921; the laser rangefinder 921 is used to emit lasers to multiple detection points on the workpiece to measure multiple detection distances; the vertical exposure machine 1 also includes a control module, which is used to calculate the flatness of the workpiece based on the multiple detection distances. Through the coordinated use of the laser rangefinder 921 and the control module, the workpiece can be detected and controlled in a timely manner to determine whether it should proceed to the next exposure operation, thus reducing the probability of producing defective workpieces.

[0014] The positioning component 91 includes a camera 911; the camera 911 is used to pick up target points on the workpiece. Optionally, the positioning component is a CCD camera.

[0015] like Figures 3-4 As shown, optionally, the frame portion 20 includes an inner frame 2a and an outer frame 2b, wherein the inner frame 2a can rotate relative to the outer frame 2b or stop rotating. After the positioning component 91 identifies the target point on the workpiece, it determines the rotation angle of the workpiece based on the test parameters, and then controls the rotation of the inner frame according to the rotation angle of the workpiece until the rotation stops after the angle of the workpiece is corrected, thus ensuring the angle accuracy during exposure.

[0016] Optionally, the vertical exposure machine 1 also includes a control mechanism that can control the rotation of the inner frame 2a based on the target information identified by the camera 911, thereby ensuring that the angle deviation is adjusted in a timely manner.

[0017] like Figures 3-4As shown, optionally, the inner frame 2a is located at the middle of one side of the frame and is hinged to the outer frame 2b via a hinge axis 24. Telescopic components 23 are installed on both adjacent sides of the inner frame 2a, and the telescopic components 23 can push the inner frame to rotate around the hinge axis 24.

[0018] Preferably, the telescopic component 23 is an electric telescopic rod 23a.

[0019] like Figures 3-4 As shown, optionally, one end of the electric telescopic rod 23a is fixedly installed with one of the inner frame 2a or the outer frame 2b, and the other end of the electric telescopic rod 23a contacts the other side of the inner frame 2a or the outer frame 2b on the corresponding side.

[0020] Optionally, each side of the inner frame is provided with an arc-shaped block (not shown in the figure) on its outer side. The arc axes of all the arc-shaped blocks are coaxial. Each side of the outer frame is provided with an arc-shaped groove on its inner side. The arc axes of the arc-shaped grooves are coaxial. Each arc-shaped block is placed in a corresponding arc-shaped groove. The inner frame rotates relative to the outer frame through the arc-shaped blocks and arc-shaped grooves.

[0021] The arc-shaped block has a toothed groove, the outer frame has a gear, and the inner frame rotates under the drive of the gear and the toothed groove. The gear can be driven by a forward and reverse motor, and the inner frame can rotate or stop rotating under the action of the forward and reverse motor.

[0022] Preferably, the forward and reverse rotating motor is a three-phase asynchronous motor.

[0023] In practice, the workpiece has multiple target points. After identifying at least three target points for the first time, the height and angle changes of the target points are judged. When a height difference occurs, the control mechanism feeds back the movement distance to the exposure mechanism 30. The exposure mechanism 30 controls the height of the exposure lens 311 to achieve the exposure accuracy of the workpiece. If an angle difference occurs, the control mechanism can control the rotation of the inner frame 2a according to the target point identification information of the positioning component 91 until it is aligned. After alignment, the target point positions on the workpiece are identified again to determine whether there is an adjustment deviation.

[0024] like Figure 2As shown, optionally, when the positioning component 91 moves, the flatness detection device 92 moves synchronously with the positioning component 91. However, this solution requires an additional flatness detection device 92 to be installed on the exposure machine. Firstly, this necessitates a readjustment of the exposure machine's structural layout to make room for the flatness detection device 92. Secondly, adding the flatness detection device 92 would require an additional flatness detection step in the exposure process, which is inconvenient and increases exposure time. Therefore, in the above embodiment, the existing positioning component 91 of the exposure machine is used, and the flatness detection device 92 moves synchronously with the positioning component 91. This simplifies setup and allows for simultaneous target pickup and flatness detection during the exposure process, improving exposure efficiency.

[0025] like Figure 2 As shown, optionally, the vertical exposure machine 1 also includes a mounting base 93, in which a motion track 94 and a moving part 95 are provided. The moving part 95 can move along the motion track 94, and the positioning component 91 and the flatness detection device 92 are both disposed in the moving part 95. By placing the positioning component 91 and the flatness detection device 92 in the moving part 95, the positioning component 91 and the flatness detection device 92 can move synchronously, saving steps and increasing the moving efficiency.

[0026] The moving part 95 includes a carrier, gears, a rack, and a motor. The motor and gears are mounted on the carrier, and the rack is mounted on a mounting base. The motor drives the gears to move the carrier along the rack. The positioning assembly 91 and the flatness detection device 92 are mounted on the carrier.

[0027] Optionally, each mounting base 93 is provided with at least one moving part 95, and each moving part 95 has at least one positioning component 91 and a flatness detection device 92.

[0028] Preferably, there are two moving parts 95, each moving part 95 has a positioning component 91 and a flatness detection device 92. By using two moving parts 95, both the upper and lower sides of the workpiece can be detected, ensuring the accuracy of the detection.

[0029] Optionally, the moving part 95 moves vertically, and during the movement, the positioning component 91 and the flatness detection device 92 installed on the moving part 95 are at the same distance from the workpiece.

[0030] like Figures 1-2 As shown in the embodiment, this embodiment provides a workpiece inspection method for a vertical exposure machine, which includes the following steps: controlling the frame part 20 to move to the detection range of the workpiece inspection mechanism 90; controlling the workpiece inspection mechanism 90 to detect the workpiece parameters of the workpiece mounted on the frame part 20. By utilizing the frame part 20 to pass through the detection range while the workpiece inspection mechanism 90 inspects the workpiece, the time for separate inspection is saved, and the inspection efficiency is accelerated.

[0031] It also includes the following steps: While the workpiece inspection mechanism (90) is controlling the workpiece parameters mounted on the frame (20), the positioning component (91) is simultaneously controlling the positioning component (91) to identify target points on the workpiece and obtain target point data. After obtaining the workpiece parameters and target point data, the frame (20) is controlled to continue moving within the exposure range of the exposure mechanism (30), and the exposure mechanism (30) is controlled to perform exposure based on the target point data. During the inspection, the frame (20) and / or the exposure mechanism (30) are adjusted based on the test data to ensure accuracy during subsequent exposures.

[0032] like Figures 1-2 as well as Figures 4-8 As shown, optionally, the exposure mechanism 30 is disposed on the support base 10 for exposing the workpiece; the frame portion 20 is erected on the support base 10, and the frame portion 20 includes a mounting portion 60 and a traction assembly 70; the mounting portion 60 is used to mount the workpiece, and the traction assembly 70 is used to flatten the workpiece on the mounting portion 60. The vertical exposure machine of this application allows the workpiece to stand upright after installation, and the traction assembly can flatten the workpiece along the direction of gravity, making it easier to flatten the workpiece and improving its flatness.

[0033] Optionally, the frame 20 may also include a control mechanism for controlling the traction assembly 70 to flatten the workpiece.

[0034] like Figures 6-8 As shown in the example, the mounting part 60 includes a first clamping part 61 and a second clamping part 62, which clamp the workpiece from both sides respectively. The first clamping part 61 is fixedly mounted on the frame part 20. The second clamping part 62 is connected to the traction assembly 70, which can move the second clamping part 62. By using the arrangement of the first clamping part 61 and the second clamping part 62 relative to the sides of the workpiece, the flatness of the workpiece can be ensured when flattening.

[0035] like Figures 6-7 As shown in the example, the traction assembly 70 includes a first traction part 71 and a second traction part 72; the first traction part 71 is used to flatten the workpiece as a whole; the second traction part 72 is used to flatten different positions of the workpiece individually. Through the two-stage flattening by the first traction part 71 and the second traction part 72, the workpiece is ensured to be free of bending; the method is to first tighten the workpiece as a whole to ensure that the workpiece is roughly flat, and after it is roughly flattened, the second traction part 72 flattens any remaining internal unevenness.

[0036] like Figure 6 , Figure 8As shown, optionally, the second clamping part 62 includes multiple clamping units 62a, and the second traction part 72 includes multiple traction units; each clamping unit 62a is clamped at a different position in the workpiece; each traction unit is disposed between the first traction part 71 and a clamping unit 62a; the first traction part 71 is used to drive all traction units to move synchronously; the second traction part 72 is used to generate different magnitudes of traction force according to the degree of deformation of the workpiece at the corresponding position. By using multiple clamping units 62a to clamp and move independently, the workpiece can be subjected to traction force at different positions, ensuring that the workpiece is tightened at any position and that the workpiece is in a flat state at any position.

[0037] like Figure 8 As shown, optionally, the traction unit 721 is an elastic element 721a.

[0038] Preferably, the elastic element 721a is a combination of one or more of the following: spring, elastic rope, etc.

[0039] Optionally, the traction unit is an electric telescopic pole; the electric telescopic pole is equipped with a tension sensor, and when the tension reaches a preset tension value, the tension sensor controls the electric telescopic pole to stop extending or retracting.

[0040] like Figures 6-8 As shown, optionally, the first traction part 71 includes a power mechanism 711 and a support part 712; the second clamping part 62 is disposed on the support part 712; the power mechanism 711 can drive the support part 712 to move vertically along the frame, thereby driving the second clamping part 62 to move to flatten the workpiece. By using the power mechanism 711 to drive the support part 712 to move, the workpiece is moved away from the first clamping part 61, thus initially flattening the workpiece as a whole. This achieves the effect of rapid overall flattening of the workpiece. Alternatively, the power mechanism 711 can be used to drive the support part 712 to move the second clamping part 62 closer to the first clamping part 61, facilitating the removal or placement of the workpiece.

[0041] like Figure 7 As shown, optionally, the power mechanism 711 includes a first motor 11c1, a rotating shaft 11c2, a conveyor belt 11c3, and a sliding rod 11c4. The first motor 11c1 and the rotating shaft 11c2 are located on the side of the frame portion 20 near the second clamping portion 62. The conveyor belt 11c3 and the sliding rod 11c4 are located on both sides of the support portion 712. The two sides of the support portion 712 are mounted on the sliding rod 11c4. The first motor 11c1 drives the rotating shaft 11c2 to rotate, the rotating shaft 11c2 drives the conveyor belt 11c3 to rotate, and the conveyor belt 11c3 drives the support portion 712 to move along the sliding rod 11c4, so that the support portion 712 moves closer to or further away from the first clamping portion 61. By using the conveyor belt 11c3 to drive the support portion 712 to move, the overall flatness of the workpiece can be ensured, thereby ensuring the exposure accuracy of the workpiece.

[0042] like Figure 5 , Figure 9 As shown, optionally, the first clamping part 61 includes a mounting member 611 and a first driving part 612; the mounting member 611 is fixed to the frame part 20, and the first driving part 612 can move away from or towards the mounting member 611. When the first driving part 612 moves towards the mounting member 611, the workpiece is clamped and fixed. Moving the first driving part 612 away from the mounting member 611 facilitates the installation or removal of the workpiece; moving the first driving part 612 towards the mounting member 611 prevents the workpiece from detaching.

[0043] like Figure 9 As shown, optionally, the first driving unit 612 includes a first clamping plate 612a and a first driving member 612b; the first driving member 612b can push the first clamping plate 612a to move towards the mounting member 611. By driving the first clamping plate 612a through the first driving member 612b, no manual operation or clamping is required, which facilitates faster installation or removal of the workpiece.

[0044] like Figure 6 , Figure 8 As shown, optionally, the second clamping part 62 includes a sliding member 621 and a second driving part 622. The sliding member 621 is mounted on the support part 712 via a slide rail, and slides along the slide rail to move away from or towards the first clamping part 61. The second driving part 622 can move away from or towards the sliding member 621. When the second driving part 622 approaches the sliding member 621, the workpiece is clamped and fixed. Moving the second driving part 622 away from the sliding member 621 facilitates the installation or removal of the workpiece; moving the second driving part 622 towards the sliding member 621 prevents the workpiece from detaching. The connection between the sliding member 621 and the support part 712 via a slide rail facilitates the movement of the sliding member 621 relative to the support part 712, thus allowing the sliding member 621 to facilitate individual flattening of the workpiece at any position during workpiece flattening operations.

[0045] like Figure 8 As shown, optionally, the second driving unit 622 includes a second clamping plate 622a and a second driving member 622b; the second driving member 622b can push the second clamping plate 622a to move towards the sliding member 621. By driving the second clamping plate 622a through the second driving member 622b, no manual operation or clamping is required, which facilitates faster installation or removal of the workpiece.

[0046] Optionally, the first drive member 612b and the second drive member 622b can be electric telescopic rods.

[0047] like Figure 1 and Figure 5As shown, optionally, the frame portion 20 includes a first frame portion 21 and a second frame portion 22. The first frame portion 21 is erected on the support base 10 and is used to mount the workpiece and make the workpiece stand upright. The second frame portion 22 is erected on the support base 10 and is used to mount the workpiece and make the workpiece stand upright. The transmission assembly 50 is used to drive the first frame portion 21 and the second frame portion 22 to move in the exposure scanning direction. And / or drive the exposure mechanism 30 to move in the exposure scanning direction.

[0048] The above method: Firstly, by having the two frame sections 20 alternately perform exposure operations, the installation waiting time can be saved and the exposure efficiency can be improved.

[0049] Secondly, the first frame portion 21 and the second frame portion 22 are erected on the support base 10, which makes the workpiece installed in the frame portion 20 stand upright. The workpiece is no longer laid flat, so there is no need to consider the problem of poor exposure effect caused by the ink on the workpiece being sucked out due to vacuuming.

[0050] Thirdly, it can also solve the problem of dust accumulation on the lower exposure lens 311 affecting exposure when the workpiece is laid flat for double-sided exposure.

[0051] like Figure 1 , Figures 10-11 As shown, optionally, the vertical exposure machine 1 also includes a transfer assembly 50, which drives the frame section 20 to move in the exposure scanning direction. By moving the exposure range of the exposure mechanism 30 in or out, it is easier to put in and take out the workpiece mounted on the frame section 20, reducing the difficulty of operation.

[0052] Optionally, there are two sets of workpiece inspection mechanisms 90, respectively located on both sides of the exposure scanning direction. When the workpiece in the frame part 20 passes through the workpiece inspection mechanism 90, the two sets of workpiece inspection mechanisms 90 are used to inspect the two surfaces of the workpiece respectively. By simultaneously inspecting both sides of the workpiece, the accuracy of the inspection is further ensured.

[0053] like Figure 1 , Figures 10-11 As shown in the example, the transmission component 50 includes a first transmission component 51 and a second transmission component 52; the first transmission component 51 is used to drive the first frame portion 21 to move in the exposure scanning direction; the second transmission component 52 is used to drive the second frame portion 22 to move in the exposure scanning direction. Thus, by alternating exposure operations with the two frames, waiting time can be saved and exposure efficiency improved.

[0054] like Figure 1As shown, optionally, the vertical exposure machine 1 also includes a first control unit, which controls the first transmission component 51 and the second transmission component 52 to drive the first frame portion 21 and the second frame portion 22 to move alternately. When the first transmission component 51 drives the first frame portion 21 to move in the exposure scanning direction, the second transmission component 52 drives the second frame portion 22 to move away from the exposure scanning direction; similarly, when the first transmission component 51 drives the first frame portion 21 to move away from the exposure scanning direction, the second transmission component 52 drives the second frame portion 22 to move in the exposure scanning direction. By driving the first frame portion 21 and the second transmission component 52 to move alternately, it can be ensured that one workpiece is exposed while another workpiece is replaced at the same time, reducing the downtime for removing and replacing workpieces after exposure and accelerating the exposure efficiency.

[0055] like Figure 1 As shown, optionally, the transmission component 50 includes a first track and a power component; the first track is disposed on the support base 10; the first frame portion 21 is mounted on the first track, and the power component drives the first frame portion 21 to move along the first track; the second transmission component 52 includes a second track and a power component; the second track is disposed on the support base 10; the second frame portion 22 is mounted on the second track, and the power component drives the second frame portion 22 to move along the second track. Using a track to move the first frame portion 21 and the second frame portion 22 effectively ensures the smoothness of the displacement of the first frame portion 21 and the second frame portion 22.

[0056] As an example, the power components in both the first transmission assembly 51 and the second transmission assembly 52 include a rack, a gear, and a first motor. The first motor is mounted on the first frame portion 21 or the second frame portion 22, and the gear is mounted on the first motor; the rack is mounted on the first track or the second track. The rotation of the first motor drives the first frame portion 21 and the second frame portion 22 to move along the track via the gear and rack. Using a rack and pinion mechanism to move the first frame portion 21 and the second frame portion 22 effectively ensures the stability of the first frame portion 21 and the second frame portion 22. At the same time, the rack and pinion mechanism allows the device to stop at an accurate position, ensuring the accuracy of the exposure.

[0057] In some embodiments, the first track and the second track are located between the first exposure mechanism 31 and the second exposure mechanism 32.

[0058] Optionally, the first track and the second track are parallel, but this application is not limited to the parallel implementation. For example, the first track and the second track are parallel to the tracks within the exposure range of the first exposure mechanism 31 and the second exposure mechanism 32, but the distance between the first track and the second track that are not within the exposure range of the first exposure mechanism 31 and the second exposure mechanism 32 gradually increases or gradually decreases.

[0059] Different track settings can be implemented according to the specific circumstances of the equipment, and this application does not impose any restrictions.

[0060] like Figure 1 , Figures 10-11 As shown, optionally, the exposure mechanism 30 includes a first exposure mechanism 31 and a second exposure mechanism 32; the first exposure mechanism 31 and the second exposure mechanism 32 are respectively disposed on both sides of the frame portion 20, and both the first exposure mechanism 31 and the second exposure mechanism 32 can independently emit exposure beams to the workpiece. This enables double-sided exposure of the workpiece mounted in the first frame portion 21 or the second frame portion 22, eliminating the need for flipping and completing double-sided exposure of the workpiece in one step, saving the time spent on flipping and further accelerating the exposure efficiency.

[0061] like Figure 10 As shown, the exposure mechanism 30 includes multiple exposure lenses 311, each of which emits an exposure beam that is perpendicular or obliquely directed onto the workpiece of the frame portion 20. By using multiple exposure lenses 311 to emit exposure beams that are perpendicular or obliquely directed onto the workpiece, the entire plate can be exposed, thus accelerating the exposure efficiency.

[0062] Preferably, the multiple exposure lenses 311 are divided into at least two exposure groups, and the exposure lenses 311 in each exposure group are arranged linearly. By using multiple exposure groups in a linear arrangement, the exposure is more uniform, ensuring the exposure quality of the workpiece.

[0063] Optionally, the exposure lenses 311 in each exposure group are arranged in a horizontal, vertical, or diagonal linear arrangement. The horizontal, vertical, or diagonal arrangement is relative to the ground, and the distance from the exposure lenses 311 to the frame portion 20 is the same to ensure the stability of the exposure beam during exposure.

[0064] Optionally, the arrangement of the exposure lenses 311 in each exposure group can also be non-linear.

[0065] Optionally, the exposure mechanism 30 also includes an exposure lens holder 312 for mounting the exposure lens 311.

[0066] like Figure 12 As shown, in one embodiment, the exposure lens 311 is fixedly installed with the exposure lens bracket 312, which means that the exposure lens 311 is fixed relative to the exposure lens bracket 312, making the exposure lens 311 more stable and ensuring the exposure effect.

[0067] like Figures 10-11 As shown, in another embodiment, the exposure lens 311 can be raised and lowered relative to the exposure lens holder 312. The exposure lens 311 can be adjusted according to the required exposure height of the workpiece, ensuring the exposure position and accuracy, and facilitating the assurance of workpiece quality.

[0068] like Figure 10 As shown, optionally, the exposure mechanism 30 also includes a motor 313, which is mounted on the exposure lens bracket 312 and controls the lifting and lowering of the exposure lens 311 via a lead screw and nut.

[0069] like Figure 1 As shown, optionally, both the first frame portion 21 and the second frame portion 22 include through holes penetrating their own first and second surfaces; the first surface is close to the first exposure mechanism 31, and the second surface is close to the second exposure mechanism 32; the first exposure mechanism 31 can emit an exposure beam onto the first surface, thereby exposing one side of the workpiece mounted in the first frame portion 21 or the second frame portion 22; the second exposure mechanism 32 can emit an exposure beam onto the second surface, thereby exposing the other side of the workpiece mounted in the first frame portion 21 or the second frame portion 22. By using the first exposure mechanism 31 and the second exposure mechanism 32 to simultaneously expose both sides of the workpiece in the first frame portion 21 or the second frame portion 22, there is no need for flipping, and the double-sided exposure of the workpiece is completed in one go, saving the time spent on flipping and further accelerating the exposure efficiency.

[0070] Optionally, the vertical exposure machine 1 also includes an adjustment assembly; the exposure mechanism 30 is mounted on the adjustment assembly, which is used to adjust the distance between the exposure mechanism 30 and the workpiece. The adjustment assembly can drive the corresponding first exposure mechanism 31 and second exposure mechanism 32 to move according to the exposure requirements, such as the exposure intensity or the exposure range, thereby ensuring that different exposure requirements are met satisfactorily.

[0071] Optionally, the workpiece is a circuit board, including PCB board, FPC board, etc.

[0072] like Figure 1 as well as Figures 5-9 As shown in the embodiment: This embodiment provides an exposure machine control method, which includes the following steps: controlling the mounting part to install the workpiece; after the installation is completed, controlling the traction assembly to pull the mounting part to move, thereby completing the flattening of the workpiece.

[0073] Operation method for installing the workpiece on the frame section 20: First, drive the first traction part 71 to move toward the mounting part, so that the distance between the first clamping part 61 and the second clamping part 62 becomes smaller, and the first pressing plate 612a separates from the mounting part 611, and the second pressing plate 622a separates from the sliding part 621. Next, the workpiece is placed between the first clamping plate 612a and the mounting member 611, and then the first clamping plate 612a is pushed by the first driving member 612b to fix the workpiece; then the other end of the workpiece is placed between the second clamping plate 622a and the sliding member 621, and then the second clamping plate 622a is pushed by the second driving member 622b to fix the workpiece; at this time, the workpiece is in a bent state.

[0074] Subsequently, the first traction unit 71 is activated, and the first traction unit 71 drives the second clamping unit 62 away from the first clamping unit 61. After the workpiece is initially flattened, the first traction unit 71 continues to drive the second clamping unit 62 away from the first clamping unit 61. Under the traction force of multiple second traction units 72, multiple second clamping units 62 flatten any position of the workpiece until any position of the workpiece is flattened, then the traction of the first traction unit 71 is stopped, and the flattening of the workpiece is completed.

[0075] like Figures 13-15 As shown, optionally, the vertical exposure machine 1 includes a moving part 80, which includes positioning members 81 on both sides and a plurality of moving members 82 located between the two positioning members 81. A second clamping part 62 and a second traction part 72 are mounted on the moving part 80. The positioning members 81 and the moving members 82 are mounted on a support part 712 and can move laterally on the support part 712. Lateral movement prevents the workpiece from tilting after installation, which could cause it to be unable to flatten.

[0076] like Figures 13-15 As shown, both the positioning element 81 and the moving element 82 can slide laterally synchronously. When the two positioning elements 81 and the multiple moving elements 82 move laterally inward, it facilitates the installation and clamping of the two corners of the workpiece; when the positioning elements 81 and the multiple moving elements 82 move laterally outward, it facilitates the flattening of the workpiece laterally.

[0077] like Figures 13-14 as well as Figures 16-17 As shown, optionally, the support part is provided with a sliding groove 85, and the positioning member 81 and the moving member 82 are provided with a slider 86. The positioning member 81 and the moving member 82 slide laterally relative to the support part via the slider 86 and the sliding groove 85.

[0078] Optionally, there are gaps between adjacent positioning members 81 and moving members 82, and between adjacent moving members 82. This prevents hard compression of the flexible circuit board and avoids damage to the circuit board.

[0079] like Figures 13-14 As shown, optionally, the moving part 80 also includes a plurality of elastic mechanisms 83, which are respectively disposed between the positioning member 81 and the moving member 82, and between two adjacent moving members 82; the elastic mechanism 83 causes the positioning member 81 and the moving member 82 to receive a force that moves them away from each other, so that they can be horizontally flattened without human intervention, ensuring the convenience of operation.

[0080] like Figure 13 , Figure 15 as well as Figure 18As shown, optionally, the moving part 80 also includes a limiting member 84, which is disposed on both sides of the frame part 20. The limiting member 84 is used to restrict the inward or outward movement of the positioning member 81. When the first traction part 71 moves downward, the positioning member 81 moves outward under the action of the elastic mechanism 83 and stops moving outward under the restriction of the limiting member 84; ensuring that the positions of the two corners of the workpiece do not shift, and under the action of the elastic force of the elastic mechanism 83, the workpiece between the two adjacent second clamping parts 62 is laterally flattened; when the first traction part 71 moves upward, the positioning member 81 moves inward under the action of the limiting member 84. In order to ensure the stability of the elastic force, the distance between adjacent positioning members 81 and moving members 82, as well as between moving members 82, will become smaller, which facilitates the installation and removal of the workpiece.

[0081] Preferably, the elastic mechanism 83 is a compression spring.

[0082] In summary, this utility model provides a vertical exposure machine that, through the positioning of the positioning component and the detection of workpiece parameters by the workpiece detection mechanism, can analyze and correct the workpiece before exposure, ensuring the accuracy of exposure.
