Description

Technical Field

[0001] The present invention relates to the field of cutting and detection technology, and in particular to a method for laser wet cutting and detection of an SMT template. Background Art

[0002] As we all know, SMT stencils are molds used to print solder paste in the SMT process. In the SMT process, they are used to transfer solder paste to the pads of the printed circuit board. The quality of the SMT stencil is crucial to the quality and production efficiency of the SMT process. Laser wet cutting of SMT stencils is a method used to process SMT stencils. To facilitate the cutting process of SMT stencils and to form real-time quality inspection of the processed SMT stencils, we have proposed a method for laser wet cutting and inspection of SMT stencils.

[0003] After searching, the Chinese patent application number CN202220598242.5 discloses a SMT template laser wet cutting processing equipment, which is roughly described as including an equipment body, a movable cover on the equipment body, and a cross bar connected to one side of the equipment body, the end of the cross bar is connected to a connecting frame, and the connecting frame includes a first connecting bar and a second connecting bar, the first connecting bar is connected to the second connecting bar, and the first connecting bar is connected to the cross bar, and a placement rack and an industrial computer are provided on the connecting frame. When in use, when only the industrial computer needs to be disassembled and repaired, only one side of the connecting frame needs to be disassembled. Part of it is enough, there is no need to disassemble the entire connecting frame, and it does not affect the placement of structures such as the keyboard. The Chinese patent application number CN201210015719.3 discloses a processing equipment for laser wet cutting and detection of SMT templates. It is roughly described as including a mobile dual-drive gantry structure, in which the Y-axis moves forward and backward to drive the X-axis to move forward and backward, and the Z-axis is fixed on the X-axis moving plate and moves left and right with the X-axis moving plate. A cutting head and a nozzle are installed on the Z-axis moving plate. When in use, cooling water is synchronously sprayed to the cutting point area below the cutting head through the nozzle, which can be used for laser wet cutting and detection of SMT templates.

[0004] Although the above two sets of existing technical solutions can both match the SMT template to form laser cutting, the former does not elaborate on the main body of the equipment in detail, that is, the specific measures of how the main body of the equipment can realize the laser wet cutting processing of the SMT template are not clear. The technical content of this part is relatively general. Although the latter technical solution can match the synchronous spraying of cooling water in the cutting point area, compressed air is used to blow away the cutting molten pool during the actual laser cutting process to ensure the laser cutting effect. Therefore, the sprayed air will blow the cooling water on the one hand, making it difficult for the cooling water to cover the cut SMT template. The effect of the cooling water needs to be further improved. Summary of the Invention

[0015] The method for SMT template laser wet cutting and detection comprises the following steps:

[0016] S1. Before use, first install the control circuit for the SMT template laser wet cutting and detection device, install the control computer for the detection camera, install the laser for the laser cutting head, install the water supply pipeline connected to the outside world for the trigger water release assembly, and install the external gas supply pipeline for the high-pressure gas guide pipe. Then, remove the clamping support frame relative to the vertical bracket, load the blank plate of the SMT template to be processed into the clamping support frame, and re-install the clamping support frame carrying the blank plate relative to the vertical bracket;

[0017] S2. Before cutting, the electric adjustment structure adjusts the position of the position support structure on the bottom side of the blank plate. After the adjustment is completed, the position support structure provides support on the bottom side of the blank plate. Then, the driven lifting frame is adjusted to correspond to the position support structure in the upper and lower directions. The position support structure drives the driven lifting frame to lower so that the elastic hollow rubber ring contacts the top end of the blank plate.

[0018] S3. After the elastic hollow rubber ring comes into contact with the top end of the blank plate, the position support structure continues to act on the driven lifting frame to further lower the driven lifting frame, which will cause the elastic hollow rubber ring to be elastically compressed in height. Along with the elastic compression of the elastic hollow rubber ring in height, the trigger water release assembly will be triggered, thereby achieving communication between the area enclosed by the elastic hollow rubber ring and the blank plate and the external water supply pipeline, forming water distribution on the surface of the blank plate. With respect to the process of water distribution on the surface of the blank plate, by controlling the effect of the position support structure on the trigger water release assembly, the water channel in the trigger water release assembly is controlled according to the water distribution situation on the surface of the blank plate, so as to control the water distribution amount on the surface of the blank plate;

[0019] S4. Then, the robot is controlled to form a synchronous spatial adjustment of the laser cutting head, the high-pressure gas guide tube and the two detection cameras. After the laser cutting head enters the cutting position relative to the blank plate, the mouth of the high-pressure gas guide tube is inserted below the water surface of the water distributed on the surface of the blank plate. Then, the laser is powered on to form a supply of laser beam for the laser cutting head. The laser beam acts on the blank plate to form cutting heating of the blank plate. High-pressure gas is ejected from the high-pressure gas guide tube to act on the heating area on the blank plate, blowing away the molten pool area on the blank plate. The detection camera monitors the cutting situation in real time. The robot drags the laser cutting head, the high-pressure gas guide tube and the two detection cameras to form relative movement relative to the blank plate, thereby realizing the cutting preparation operation of the blank plate to the SMT template.

[0020] Compared with the prior art, the present invention provides a method for laser wet cutting and detection of SMT templates, which has the following beneficial effects:

[0021] (1) In the present invention, a laser cutting execution structure corresponding to the SMT template is formed by the equipment body, and a support space is provided for the subsequent clamping support frame to facilitate auxiliary positioning of the blank plate of the SMT template during the cutting process and ensure the cutting quality.

[0022] (2) In the present invention, by matching the design of the water distribution structure, a water distribution structure relative to the SMT template is formed, and the SMT template can be matched to form an area enclosure to provide storage space for the distributed water, thereby achieving the effect of precise water distribution and water saving.

[0023] (3) In the present invention, through the design of the position support structure, a bottom support can be formed relative to the SMT template to reduce the deformation of the SMT template during the cutting process, thereby reducing the cutting error, and can be matched with the water distribution structure to form an auxiliary drive to achieve the creation of water distribution space and the distribution of water sources.

[0024] (4) In the present invention, the design of the trigger-distribution water distribution assembly can be used to coordinate with the position of the driven lifting frame to form the on-off control of the water distribution channel. The linkage effect between the various parts is better and the practicality is better.

[0025] (5) In the present invention, by providing a clamping support frame and detachable installation relative to the longitudinal bracket, on the one hand, it can provide clamping support for the SMT template, and on the other hand, it also improves the operational convenience when placing and removing the SMT template.

[0047] It also needs to be further explained that the driven lifting frame 9 is installed with a touch water distribution assembly, and the touch water distribution assembly and the driven lifting frame 9 are controlled to operate by the position supporting structure. The touch water distribution assembly comprises a water inlet pipe 27 and a pipe-in bracket 28. The water inlet pipe 27 is fixedly connected with the driven lifting frame 9.

In this application, we only use them and do not improve their structure and function. Their setting method, installation method and electrical connection method can be understood by those skilled in the art as long as they are debugged according to the requirements of the instruction manual. Here, we will not repeat them.

[0049] In summary, the working principle of the SMT template laser wet cutting and detection method is as follows: before use, first install the control circuit for the SMT template laser wet cutting and detection device, that is, install the control circuit for the robot 3, the detection camera 5, the first servo motor 20, the second servo motor 21, the third servo motor 22, the electric telescopic rod 24, the electromagnet 25 and the fourth servo motor 48, and install the control computer for the detection camera 5. The control computer can store and analyze the information taken by the detection camera 5. The laser cutter 4 is equipped with a laser cutter, the water inlet pipe 27 in the water release assembly is connected to the water supply pipeline outside, the high-pressure gas guide pipe 6 is equipped with a gas supply pipeline outside, then the clamping support frame is removed relative to the vertical support 7, the blank plate for processing the SMT template is loaded into the clamping support frame, and the clamping support frame carrying the blank plate is reinstalled relative to the vertical support 7. When the blank plate is loaded relative to the clamping support frame, first rotate any one of the first parallel rod 36 and the second parallel rod 37 to make the support ring frame 34 and the pressing ring frame 35 move apart relative to each other, keep the relative separation state of the support ring frame 34 and the pressing ring frame 35, insert the blank plate into the space between the support ring frame 34 and the pressing ring frame 35, then control the pressing ring frame 35 to fall relative to the support ring frame 34 until the support ring frame 34 and the pressing ring frame 35 are close to each other to form auxiliary support for the blank plate. The pressing state between the support ring frame 34 and the pressing ring frame 35 is controlled manually, and the structure formed by the support ring frame 34, the pressing ring frame 35 and the blank plate is moved. The support ring frame 34 is placed in the two vertical supports 7. Before the support ring frame 34 and the pressing ring frame 35 are placed relative to the vertical support 7, the front end of the front drive pressing hook 38 should be pressed down. As shown in Figure 11As shown, when the front driving pressing hook 38 is pressed down to make the rear end hook rise, the driving connecting plate 42 will form an auxiliary push of the synchronous frame 40, and the synchronous frame 40 will be pushed forward to form elastic compression on the limit spring 41, and the limit spring 41 will also rotate relative to the longitudinal bracket 7 during the process of elastic compression. When the limit spring 41 rotates through the ultimate compression length, it will enter the extended state again. In this state, the rotation and raising of the front driving pressing hook 38 can be controlled. Since the synchronous frame 40 will also drive the driven connecting plate 43 to move, the rear following pressing hook 39 will also form under the movement of the driven connecting plate 43. Rotate and raise so that there is enough space on the longitudinal bracket 7 to accommodate the support ring frame 34 and the pressing ring frame 35. After the support ring frame 34 and the pressing ring frame 35 are placed relative to the longitudinal bracket 7, press the front driving pressing hook 38 downward to make the synchronous frame 40 move backward relative to the longitudinal bracket 7, so that the limit spring 41 rotates backward through the extreme compression position, and achieves the synchronous downward drive of the front driving pressing hook 38 and the rear follower pressing hook 39. In this state, the support ring frame 34 and the pressing ring frame 35 will be driven together to approach the longitudinal bracket 7, so as to form a contact and pressing positioning with the matching pressing ring frame 35, thereby forming the positioning before the blank plate is cut.

[0050] Before cutting, the electric adjustment structure adjusts the position of the position support structure on the bottom side of the blank plate. After the adjustment is completed, the position support structure is used to form a support on the bottom side of the blank plate. Then the driven lifting frame 9 is adjusted to form an upper and lower correspondence with the position support structure, and the driven lifting frame 9 is driven to be lowered by the action of the position support structure, so that the elastic hollow rubber ring 10 is in contact with the top of the blank plate. The two lead screws 18 are respectively threadedly connected with the two threaded cylinders 19. The second servo motor 21 is powered on to realize the left and right movement drive of the displacement frame 8, and the third servo motor 22 is powered on to realize the left and right movement drive of the adjustment frame 17. Through the coordinated operation of the second servo motor 21 and the third servo motor 22, the upper and lower correspondence of the adjustment frame 17 and the displacement frame 8 can be achieved, and the electric telescopic rod 24 is powered on to realize the height adjustment of the lifting inner frame 23 relative to the adjustment frame 17. When the lifting inner frame 23 forms upper and lower contact with the blank plate, the power is stopped. The operation of the movable telescopic rod 24 is followed by the power supply of the electromagnet 25, which makes the electromagnet 25 generate an electromagnetic field acting on the magnetic iron column 26. Under the action of the electromagnetic field, the driven lifting frame 9 can be made to fall relative to the displacement frame 8. After the elastic hollow rubber ring 10 forms contact with the top of the blank plate, the position support structure continues to act on the driven lifting frame 9 to make the driven lifting frame 9 further lowered, which will cause the elastic hollow rubber ring 10 to be elastically compressed in height. Along with the elastic compression of the elastic hollow rubber ring 10 in height, the trigger water release component will be triggered, thereby realizing the connection between the area enclosed by the elastic hollow rubber ring 10 and the blank plate and the external water supply pipeline, forming water distribution on the surface of the blank plate. With respect to the process of water distribution on the surface of the blank plate, by controlling the effect of the position support structure on the trigger water release component, the on-off control of the water channel in the trigger water release component is formed according to the water distribution situation on the surface of the blank plate, so as to control the water distribution amount on the surface of the blank plate, as shown in the attached figure. Figure 6As shown, the triggering process of the water release assembly is that when the compression deformation of the elastic hollow rubber ring 10 causes the bottom end of the lifting rod 30 to come into contact with the inner bottom wall of the elastic hollow rubber ring 10, the lifting rod 30 will bear the supporting force, and the lifting rod 30 will overcome the elastic force of the sealing spring 33 to make the lifting rod 30 relatively rise in the water inlet pipe 27, and finally reach the separation of the conical ring 31 relative to the sealing outer ring 32. In this state, there is a certain height difference between the conical ring 31 and the sealing outer ring 32, so that a passage is formed inside the water inlet pipe 27. Conversely, when the driving force acting on the lifting rod 30 disappears, the conical ring 31 will move relative to the sealing outer ring 32 under the action of the sealing spring 33. In this state, the conical ring 31 and the sealing outer ring 32 are fitted inside and outside, so that the water channel in the water inlet pipe 27 is separated. Then, the laser cutting head 4, the high-pressure gas guide pipe 6 and the two detection cameras 5 are synchronously adjusted in space by controlling the robot 3. After the laser cutting head 4 enters the cutting position relative to the blank plate, the mouth of the high-pressure gas guide pipe 6 is just inserted below the water surface of the water distributed on the surface of the blank plate. After that, the laser is powered on to supply the laser cutting head 4 with a laser beam. The laser beam acts on the blank plate to form cutting heating of the blank plate. The high-pressure gas is ejected from the high-pressure gas guide pipe 6 to act on the heating area on the blank plate, forming a blow-off for the molten pool area on the blank plate.

[0051] During the cutting process, the detection camera 5 monitors the cutting situation in real time. The robot 3 drags the laser cutting head 4, the high-pressure gas guide tube 6 and the two detection cameras 5 to form relative movement relative to the blank plate to realize the cutting preparation operation of the blank plate to the SMT template. In order to ensure the cutting of the laser cutting head 4 while avoiding the laser cutting head 4 wading through water, the amount of water distributed on the surface of the blank plate should be controlled. During the cutting process of the laser cutting head 4, the water surface of the water distribution is located on the lower side of the laser cutting head 4. At the same time, the nozzle of the high-pressure gas guide tube 6 is inserted below the water surface of the water distributed on the surface of the blank plate, which can realize the output of compressed air from below the water surface to ensure the blank The covering effect of the water on the surface of the plate on the blank plate, since the opening and closing of the water channel inside the trigger water release assembly is mainly controlled by the magnetic strength of the electromagnet 25, the control circuit of the electromagnet 25 is connected to the control computer, and the control computer forms a corresponding control of the strength of the current passed into the electromagnet 25 by detecting the image information collected in real time by the camera 5, and then achieves the water volume control of the water distributed on the surface of the blank plate to ensure the smooth progress of the cutting operation, and during the cutting movement of the laser cutting head 4, the fourth servo motor 48 is always running to realize the dynamic rotation control of the rotating mounting frame 47 relative to the fixed annular disk 46, so that the position of the high-pressure gas guide pipe 6 is always In line with the forward direction of the laser cutting head 4, the high-pressure air output by the high-pressure gas guide tube 6 can move below the water surface toward the side where the cutting is completed, reducing the impact of underwater bubbles on the cutting of the area to be cut on the blank plate, and since the specifications of the holes and gaps cut on the blank plate are relatively small, the leakage of water distribution on the surface of the blank plate through the cut holes and gaps is within a reasonable loss range, and can be timely replenished by triggering the water distribution component to achieve stable coverage of the water distribution on the surface of the blank plate. After the cutting operation of a single area on the blank plate is completed, the power supply of the electromagnet 25 is cut off, so that the driven lifting frame 9 is under the action of the connecting spring 11. The lower part is formed to rise away from the blank plate, and the electric telescopic rod 24 is used to control the movement and lowering of the lifting inner frame 23. Then, the first servo motor 20, the second servo motor 21 and the third servo motor 22 are used to work together to realize the position switching of the displacement frame 8 and the adjustment frame 17 relative to the blank plate. Then, the previous steps are repeated completely to achieve the cutting operation at the next position on the blank plate. After the cutting of a single area is completed, the water distribution that has been formed will fall into the semi-cylindrical recovery groove on the lower side of the main frame 1 by itself. After the adjustment is completed, the water distribution is re-formed, which can reduce the impact of the cutting splash material already covered in the water on the next cutting operation.
