Abstract
Description
Technical Field
[0001] This application relates to the field of screen printing plate technology, and in particular to a screen printing plate inspection and repair device. Background Technology
[0002] The screen printing stencils used in the production of printed circuit boards will inevitably have pinholes and light transmission defects after production, while other defects account for a relatively small proportion. When the number of defects is large, manual inspection of the screen printing stencil is required to locate the defects before repair.
[0003] In related technologies, manual visual inspection is generally used to locate defects in screen printing stencils. However, the main problems with manual visual inspection are the unstable anomaly detection rate, long inspection time, and the significant eye damage caused by prolonged exposure to light during inspection. Common defects in screen printing stencils include small light-transmitting points and blocked holes (other defects such as line deformation and incompleteness are irreparable and require replacement). These light-transmitting points are difficult to detect with the naked eye, and even after detection, they require repair. Blocked holes also need to be cleared, both of which are done manually, resulting in long inspection and repair times and low efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0049] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.
[0050] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0051] Please refer to Figures 1 to 4 This application provides a screen printing stencil inspection and repair device, including a clamping component, an inspection component 30, and a repair component 40.
[0052] The clamping component is used to fix the screen printing stencil 200.
[0053] Clamping components may include gripper cylinders, etc., to fix the screen printing stencil 200, so as to facilitate subsequent scanning, inspection and repair of the screen printing stencil 200.
[0054] The detection component 30 is used to scan and detect the screen printing plate 200, and the repair component 40 is used to repair the screen printing plate 200. Both the detection component 30 and the repair component 40 can move relative to the screen printing plate 200.
[0055] The detection component 30 may include a camera for detecting perforations or damage to the screen printing stencil 200. The repair component 40 may include a filler agent, which can be applied to the perforations of the screen printing stencil 200. Both the detection component 30 and the repair component 40 may move relative to the screen printing stencil 200 along its length and / or width.
[0056] As can be seen from the above, the screen printing stencil inspection and repair equipment provided in this application embodiment can first fix the screen printing stencil 200 by clamping components, then move the inspection component 30 relative to the screen printing stencil 200 to scan and inspect different parts of the screen printing stencil 200, and finally move the repair component 40 relative to the screen printing stencil 200 and use the repair component 40 to repair the defects of the screen printing stencil 200 detected by the inspection component 30, thus completing the inspection and repair process of the screen printing stencil 200. The operation is simple and convenient, saves time and effort, and has high efficiency.
[0057] The screen printing stencil inspection and repair equipment provided in this application saves manpower, improves the detection rate and repair speed of screen printing stencil 200 abnormalities, and reduces the occurrence of quality problems.
[0058] In this embodiment, the clamping component includes a support assembly 10, which is used to support the bottom of the screen printing stencil 200.
[0059] By adopting the above solution, the screen printing stencil 200 can be supported, thereby preventing it from shaking due to excessive weight, which would affect subsequent scanning, inspection and repair of the screen printing stencil 200.
[0060] Understandably, the screen printing plate 200 resists the support component 10 under its own gravity.
[0061] Optionally, the support assembly 10 includes a support member 101, which has a support groove 11. The bottom of the screen printing stencil 200 is accommodated in the support groove 11. The support assembly 10 also includes a first locking member 12, which penetrates the inner wall of the support groove 11 and abuts against the screen printing stencil 200. The first locking member 12 is threadedly connected to the support member 101. Alternatively, the first locking member 12 can be configured as a clamping cylinder.
[0062] With this configuration, the bottom of the screen printing stencil 200 can be fixed by the first locking member 12, preventing the bottom of the screen printing stencil 200 from moving randomly within the receiving groove.
[0063] For example, the first locking element 12 is configured as a clamping cylinder, which makes clamping faster.
[0064] Optionally, the clamping component also includes two limiting components 20, which are respectively disposed on both sides of the screen printing plate 200 and are used to abut against the sides of the screen printing plate 200.
[0065] This setting allows for restraint and limiting of the two sides of the screen printing stencil 200, thereby preventing the screen printing stencil 200 from shaking and affecting subsequent scanning, inspection, and repair.
[0066] The limiting component 20 includes a limiting member 22 and a first power member 21 connected to each other. The limiting member 22 is used to hold the side of the screen printing plate 200, and the first power member 21 is used to drive the limiting member 22 to move closer to and away from the screen printing plate 200.
[0067] With this setup, the screen printing stencil 200 can be placed between the two limiting components 20 first, and then the first power component 21 can drive the limiting component 22 to approach the screen printing stencil 200 to support the side of the screen printing stencil 200, which facilitates subsequent scanning, inspection and repair of the screen printing stencil 200. After scanning, inspection and repair of the screen printing stencil 200, the first power component 21 can also drive the limiting component 22 away from the screen printing stencil 200 to remove the screen printing stencil 200 from between the two limiting components 20.
[0068] It is understandable that, for the two limiting components 20, one limiting component 20 can be configured to include a connected limiting member 22 and a first power member 21, while the other limiting component 20 only includes a limiting member 22. In use, the screen printing plate 200 is first placed between the two limiting components 20, and abuts against the limiting member 22 of the limiting component 20 without the first power member 21. Then, the first power member 21 of the limiting component 20 with the first power member 21 drives the limiting member 22 closer to the screen printing plate 200, thus abutting against the side of the screen printing plate 200. For the same limiting component 20, multiple limiting members 22 and multiple first power members 21 can be provided to better limit the screen printing plate 200 and ensure the positional stability of the screen printing plate 200 during subsequent inspection and repair processes. The first power member 21 may include a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.
[0069] Optionally, in order to make the movement of the limiting member 22 more stable when the first power member 21 drives the limiting member 22 to approach and move away from the screen printing plate 200, a guide post 23 connected to the limiting member 22 can be provided. When the first power member 21 drives the limiting member 22 to approach and move away from the screen printing plate 200, the guide post 23 and the guide seat adapted thereto are slidably connected, thereby making the movement of the limiting member 22 more stable.
[0070] Optionally, the limiting member 22 is provided with a limiting groove 24, and the side of the screen printing plate 200 is accommodated in the limiting groove 24. The limiting component 20 also includes a second locking member 25, which penetrates the inner sidewall of the limiting groove 24 and abuts against the screen printing plate 200. The second locking member 25 is threadedly connected to the limiting member 22, or the second locking member 25 is configured as a clamping cylinder.
[0071] With this configuration, the side of the screen printing stencil 200 can be fixed by the second locking member 25, preventing the side of the screen printing stencil 200 from moving freely within the limiting groove 24.
[0072] For example, the second locking element 25 is configured as a clamping cylinder, which makes clamping faster.
[0073] Rubber pads can be installed on the bottom and side walls of the limiting groove 24 to better fix the screen printing stencil 200 and avoid damage to the screen printing stencil 200.
[0074] Please refer to Figures 1 to 3 as well as Figures 5 to 8 In this embodiment, the detection component 30 includes two sets of array cameras 31, which are arranged alternately.
[0075] By adopting the above scheme, the patterns scanned by the two array cameras 31 can be stitched together, achieving a wider area in a single scan, better scanning and detection of the screen printing plate 200, and improving the scanning rate.
[0076] Optionally, the screen printing stencil inspection and repair equipment also includes an illumination component 50 for illuminating the screen printing stencil 200.
[0077] With this setup, the screen printing plate 200 can be illuminated by the illumination component 50, which facilitates the scanning and detection of the screen printing plate 200 by the two array cameras 31.
[0078] For example, the lighting component 50 may include an array of light sources.
[0079] The repair component 40 includes a repair component 41, a repair power component 42, and a distance measuring component 43. The repair component 41 is used to repair the screen printing plate 200. The repair power component 42 is used to move the repair component 41 closer to and further away from the screen printing plate 200. The distance measuring component 43 is connected to the repair component 41 and is used to detect the distance between itself and the screen printing plate 200.
[0080] This configuration allows the measuring element 43 to better determine the distance between itself and the screen printing stencil 200, thereby better determining the distance between the repair part 41 and the screen printing stencil 200. This enables more precise positioning of the repair part 41 and the screen printing stencil 200 during repair, preventing poor repair results due to insufficient movement of the repair part 41 or damage to the screen printing stencil 200 due to excessive distance.
[0081] For example, the repair power component 42 may include a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc. The repair component 41 may include a photosensitive gel pen, etc. The rangefinder 43 may include a laser rangefinder, etc.
[0082] In this embodiment, the screen printing stencil inspection and repair device further includes a cleaning component 60, which is movable relative to the screen printing stencil 200 and is used to clean the blocked holes of the screen printing stencil 200.
[0083] By adopting the above solution, the cleaning component 60 can be used to clean the blocked holes of the screen printing plate 200.
[0084] Optionally, the cleaning component 60 includes a flushing head 61 and a second power component 62 connected to each other. The flushing head 61 is used to spray water onto the screen printing plate 200, and the second power component 62 is used to drive the flushing head 61 to move closer to and away from the screen printing plate 200.
[0085] With this setup, the water jet head 61 can be used to spray water onto the screen printing plate 200 to clean the clogged areas of the screen printing plate 200.
[0086] For example, the second power component 62 may include a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc. The water jet head 61 may be configured as a fan-shaped cover, etc. The water jet head 61 can spray ultrasonic pulse water jets onto the screen printing plate 200 using the principle of high-pressure pulses.
[0087] For example, the second power component 62 includes a linear motor, and the flushing head 61 is mounted on the slider of the linear motor.
[0088] The cleaning component 60 also includes a water absorption component 70, which includes a water absorption head 71 and a third power component 72. The water absorption head 71 and the water rinsing head 61 are respectively arranged on both sides of the screen printing plate 200, and the water absorption head 71 and the water rinsing head 61 are arranged correspondingly. Water can flow to the water absorption head 71. The third power component 72 is used to drive the water absorption head 71 to move closer to and away from the screen printing plate 200.
[0089] With this setup, the water jet from the flushing head 61 to the screen printing plate 200 can be recovered through the absorption component.
[0090] It should be noted that the suction head 71 and the flushing head 61 can be arranged opposite to each other and connected. The suction head 71 and the flushing head 61 have the same size and shape, and can fit tightly together during operation to form a relatively sealed space. The water jetted by the flushing head 61 onto the screen printing plate 200 flows to the suction head 71 after passing through the screen printing plate 200. The third power component 72 may include a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc. The suction head 71 may be configured as a fan-shaped cover, etc.
[0091] Optionally, the flush head 61 and / or the suction head 71 are provided with a gas interface 611.
[0092] With this configuration, high-pressure gas can be introduced into the rinsing head 61 through the gas interface 611 to blow away the water remaining on the screen printing plate 200; and / or, air can be extracted from the suction head 71 through the gas interface 611 to better recover the water jet sprayed from the rinsing head 61 onto the screen printing plate 200.
[0093] Optionally, the absorbent head 71 is provided with an absorbent cushion 711, which is used to adhere to the screen printing plate 200.
[0094] This design allows the absorbent head 71 to better fit the screen printing stencil 200, preventing damage to the screen printing stencil 200.
[0095] Optionally, the flushing head 61 is provided with a flushing buffer pad 612, which is used to fit against the screen printing plate 200.
[0096] This design allows the flushing head 61 to better fit with the screen printing plate 200, preventing damage to the screen printing plate 200.
[0097] Please refer to Figures 1 to 8 In this embodiment, the screen printing plate inspection and repair equipment includes a power component. The power component is used to drive the inspection component 30 to move relative to the screen printing plate 200 along the length and width directions of the screen printing plate 200. The power component is also used to drive the repair component 40 to move relative to the screen printing plate 200 along the length and width directions of the screen printing plate 200.
[0098] By adopting the above solution, the power component can be used to drive the detection component 30 and the repair component 40 to move relative to the screen printing plate 200 along the length and width directions of the screen printing plate 200, thereby enabling the detection and repair of the screen printing plate 200 at various positions and avoiding the problem of missed detection and missed repair.
[0099] Optionally, the power components include a first drive assembly 80, a second drive assembly 90, and a third drive assembly 100. The first drive assembly 80 is used to drive the detection assembly 30 to move relative to the screen printing plate 200 along the width direction of the screen printing plate 200. The second drive assembly 90 is used to drive the repair assembly 40 to move relative to the screen printing plate 200 along the width direction of the screen printing plate 200. The third drive assembly 100 is used to drive the detection assembly 30, the first drive assembly 80, the repair assembly 40, and the second drive assembly 90 to move together relative to the screen printing plate 200 along the length direction of the screen printing plate 200.
[0100] This design allows for a simpler and more compact structure for the power components.
[0101] The first drive assembly 80, the second drive assembly 90, and the third drive assembly 100 may each include cylinders, hydraulic cylinders, lead screw motors, and linear motors, etc.
[0102] The power components also include a gantry 120 and an annular truss 130. A third drive assembly 100 is installed on the left side of the gantry 120, which includes a linear motor. A linear guide rail is installed parallel to the right side of the gantry 120. One end of the annular truss 130 is fixed to the slider of the linear motor, and the other end is fixed to the slider of the linear guide rail. Driven by the linear motor, it moves up and down, that is, it moves relative to the screen printing plate 200 along the length direction of the screen printing plate 200.
[0103] The limiting component 20 is connected to the gantry 120. The detection component 30, repair component 40, lighting component 50, cleaning component 60, water absorption component 70, first drive component 80 and second drive component 90 are all set on the annular truss 130. The detection component 30, water absorption component 70 and first drive component 80 are set on one side of the screen printing plate 200, and the repair component 40, lighting component 50, cleaning component 60 and second drive component 90 are set on the other side of the screen printing plate 200. The third drive component 100 is used to drive the annular truss 130 to move relative to the screen printing plate 200 along the length direction of the screen printing plate 200.
[0104] For example, both the first drive assembly 80 and the second drive assembly 90 include a lead screw motor. The lead screw is mounted on the annular truss 130 via a bearing seat. The detection assembly 30 and the repair assembly 40 are fixed to the lead screw nut and the guide rail slider of the upper and lower guide rails via connectors. The motor drives the lead screw through a coupling, and the lead screw drives the detection assembly 30 and the repair assembly 40 to move left and right. When the detection assembly 30 and the repair assembly 40 move, they move up and down together, and can move left and right independently.
[0105] Please refer to Figures 1 to 8In this embodiment, the screen printing plate inspection and repair equipment also includes a control system 110, and the inspection component 30 and the repair component 40 are both electrically connected to the control system 110.
[0106] By adopting the above scheme, the control system 110 can automatically control the repair component 40 to repair the screen printing plate 200 according to the defects detected by the detection component 30. The detection and repair process of the screen printing plate 200 is simpler and more convenient, saving time and effort and increasing efficiency.
[0107] It should be noted that the control system 110 may include a programmable logic controller or a microcontroller. The lighting component 50, cleaning component 60, water absorption component 70, first drive component 80, second drive component 90, and third drive component 100 can all be electrically connected to the control system 110.
[0108] The usage process of the screen printing plate inspection and repair equipment provided in the above embodiments is as follows:
[0109] First, the screen printing stencil 200 is manually placed between the two limiting components 20. The support component 10 supports the bottom of the screen printing stencil 200. The first power component 21 of the right limiting component 20 drives the limiting component 22 to move closer, pressing the screen printing stencil 200 to the left. The first locking component 12 and the second locking component 25 then move to press the screen printing stencil 200 backward, completing the clamping action of the screen printing stencil 200.
[0110] Next, the manual input of CAM (Computer Aided Manufacturing) data for the corresponding screen printing plate 200 into the control system 110. After the control system 110 identifies and analyzes the CAM data, the manual input of four alignment target points and the input of the screen printing plate 200 dimensions and the distance in the X / Y directions from the lower left corner target point of the screen printing plate 200 to the edge of the screen in the corresponding screen printing plate. After the data conversion is completed, scanning is started. The array camera 31 identifies and aligns the screen according to the selected alignment target point positions and calculates the actual screen pattern expansion and contraction. Within the tolerance range, the CAM data pattern expansion and contraction is proportionally enlarged or reduced according to the actual pattern expansion and contraction to improve the accuracy of pattern matching.
[0111] After the target alignment is completed, scanning begins. When the array camera 31 is working, the illumination component 50 will move to a position opposite to the array camera 31 to provide sufficient light conditions. After the array camera 31 scans the complete pattern, the system automatically compares the actual pattern of the scanned silkscreen 200 with the pattern in the CAM data, marks the defect and abnormal position and classifies the abnormality. Then, the abnormality and defect are manually checked. The array camera 31 moves to the corresponding defect position and magnifies the image. The operator judges whether the abnormality needs to be repaired.
[0112] If repair is needed, the screen printing plate inspection and repair equipment will repair it according to the type of defect after confirmation.
[0113] If the defect is a light-transmitting point, the center of the photosensitive gel pen in the repair component 40 will move to the corresponding defect coordinate position. The laser rangefinder on one side of the photosensitive gel pen can provide the distance of the defect position in the front-back direction, forming a three-dimensional coordinate with the up-down and left-right coordinates to guide the position movement of the photosensitive gel pen tip. This makes the position and distance positioning of the photosensitive gel pen tip and the screen printing plate 200 more accurate, preventing poor repair effect or damage to the mesh due to insufficient movement of the photosensitive gel pen.
[0114] If the defect is a blockage, the center of the flushing head 61 of the cleaning component 60 moves to the defect coordinate, and the water suction component 70 connected to the detection component 30 also moves to the position opposite to the flushing head 61. With the assistance of the laser rangefinder, the front end of the water suction head 71 and the flushing head 61 are pressed together. The flushing head 61 emits ultrasonic pulse water flow and stops after working for a certain period of time. The gas interface 611 on the flushing head 61 starts to enter high-pressure gas, and at the same time, the water suction component 70 also starts to work. The water flow can be cleaned in a short time. The water sucked out by the water suction component 70 can be recycled as the water source for the flushing head 61.
[0115] After the defect is repaired, the array camera 31 moves back to the corresponding defect location to confirm whether the anomaly has been repaired.
