Description

Technical Field

[0001] The present invention relates to the field of laser steel mesh hole repairing, and in particular to a precise laser steel mesh hole repairing device and method. Background Art

[0002] Laser stencil is a tool used for SMT patch processing, also known as a template or silk screen. It is made of stainless steel or other metal materials and has a series of openings that match the corresponding component pad positions on the printed circuit board. These openings are used to print solder paste to ensure that the solder paste can be accurately deposited in the correct position on the printed circuit board.

[0003] In the prior art, after a long period of use, the mesh inside the laser steel mesh is easily damaged, which makes the steel mesh unusable. The damaged mesh needs to be repaired with glue, and then the repaired position needs to be re-drilled. For example, the utility model patent with publication number CN214416861U discloses a precise laser steel mesh hole-filling device, which includes a workbench, a hole-filling mechanism is fixedly installed on the top of the workbench, and a universal wheel is fixedly installed on the four corners of the workbench.

[0004] In the above case, during the glue filling process of the laser steel mesh, due to the small mesh size, it is difficult for the glue filling mechanism to accurately move to the center of the mesh, which can easily cause glue leakage. On the one hand, it is not conducive to fully filling the mesh, and on the other hand, it is easy to contaminate the surrounding meshes, thereby causing the meshes at other positions to be blocked by glue.

[0005] To this end, the present invention proposes a precise laser steel mesh hole filling device and method to solve the above-mentioned problems. Summary of the invention

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a precise laser steel mesh hole filling device, comprising: A positioning platform, the positioning platform is used to position the laser steel mesh; A driving block, wherein the top of the driving block is slidably connected to the top of the positioning platform, the bottom of the driving block is fixedly connected to a cylinder, the bottom of the telescopic rod of the cylinder is fixedly connected to a mounting block, and a T-shaped sliding groove is provided at the bottom of the mounting block; A slider, wherein the slider is slidably connected in the T-shaped slide groove, a mounting shell is fixedly connected to the bottom of the slider, a connecting rod assembly is slidably connected to the inner wall of the mounting shell, and an expansion capsule is arranged at the bottom end of the connecting rod assembly; A U-shaped flip frame, wherein the top of the U-shaped flip frame is rotatably connected to the side wall of the bottom end of the mounting shell, the bottom end of the U-shaped flip frame is fixedly connected to a glue filling injection tube, and the bottom end of the glue filling injection tube is provided with a glue filling port to inject glue into the mesh; A lifting and adjusting component, the lifting and adjusting component is used to lift and adjust the connecting rod component to adjust the distance between the expansion capsule and the mesh; A flip driving assembly, the flip driving assembly is used to drive the U-shaped flip frame to rotate so that the central axis of the glue filling port coincides with the vertical line of the center point of the expansion capsule; Specifically, in the prior art, during the process of glue filling for the laser steel mesh, due to the small size of the mesh, it is difficult for the glue filling mechanism to accurately move to the center of the mesh, which easily causes glue leakage. On the one hand, it is not conducive to fully filling the mesh, and on the other hand, it is easy to contaminate the surrounding mesh, thereby causing the mesh at other positions to be blocked by glue. The technical solution can solve the above problems. The specific operation is as follows: first, a patch is attached to the bottom of the position where the laser steel mesh needs to be glued to prevent leakage during glue filling, and then the laser steel mesh is placed on the positioning table. The laser steel mesh is positioned by the positioning table. It can be positioned by plugging the positioning pins with the laser steel mesh frame, or by other methods, so that the laser steel mesh remains stable during the glue filling process; After positioning is completed, the drive block is adjusted to move the mounting shell closer to the position where glue needs to be added, so that the expansion capsule moves to the top of the mesh, and then the cylinder is started to move the telescopic rod of the cylinder downward, so that the expansion capsule is inserted into the mesh. At this time, the expansion capsule is in a contracted state to facilitate insertion into the mesh, and the bottom of the limit plate contacts the top surface of the laser steel mesh; After the expansion capsule is inserted into the mesh, it expands. Due to the limiting effect of the limiting plate, the expansion capsule expands toward the side wall of the mesh and eventually fills the mesh. During the expansion of the expansion capsule, it contacts and squeezes the inner wall of the mesh. The expansion capsule is pushed by the squeezing force, so that the mounting shell drives the slider to slide along the T-shaped slide groove, and finally the center of the expansion capsule coincides with the center of the mesh. Then, the lifting and adjusting assembly is activated to move the expansion capsule upward and away from the mesh to make way for the U-shaped turning frame to turn over; Then start the flip drive assembly to rotate the U-shaped flip frame so that the glue injection tube is vertically located above the laser steel mesh. At this time, the central axis of the glue filling port coincides with the vertical line of the center point of the expansion capsule, so that the glue filling port is located directly above the center position of the mesh. Finally, glue is injected into the mesh through the glue filling injection tube, so that the glue enters the mesh and diffuses to the periphery from the center position of the mesh, and finally fills the mesh. On the one hand, it is beneficial to fully fill the mesh, and on the other hand, it is beneficial to reduce the occurrence of glue leakage, avoid glue contaminating the surrounding meshes, and cause the meshes at other positions to be blocked by glue.

[0007] Preferably,, further comprising: A pressure sensor, wherein the pressure sensor is fixedly connected to the top wall of the cavity; The slider is an induction electromagnetic block, and the inner wall of the T-shaped slide groove is fixedly connected with a U-shaped metal strip; Specifically, by setting a pressure sensor, after the expansion capsule fully fills the mesh, in the process of continuing to inject gas into the cavity, the expansion capsule no longer expands due to the obstruction of the side wall of the mesh, so that a sealed space is formed between the cavity and the expansion capsule. In the process of injecting gas into the space, the pressure in the cavity increases linearly. The pressure change information is detected by the pressure sensor. Based on the detected pressure change information, the induction electromagnetic block and the external air pump are started in a distributed manner, so that the induction electromagnetic block generates magnetic force and is magnetically adsorbed with the U-shaped metal strip, so that the installation shell is positioned to position the glue filling injection tube and improve the stability during the glue filling process. The external air pump is turned off and the injection of gas into the cavity is stopped, which is conducive to stabilizing the shape of the expansion capsule after it leaves the mesh and avoiding further expansion of the expansion capsule. After the glue filling is completed, the external air pump is controlled to extract the gas in the expansion capsule, causing the expansion capsule to shrink. After the expansion capsule shrinks, the pressure in the cavity decreases and returns to the initial value. The initial pressure value is detected by the pressure sensor, causing the magnetic force of the induction electromagnetic block to disappear, and the induction electromagnetic block cancels the positioning and adsorption with the U-shaped metal strip, allowing the induction electromagnetic block to slide freely in the T-shaped slide groove to prepare for the next adjustment.

[0008] Preferably, it also includes: A compression plate, the compression plate being slidably connected to the inner wall of the glue filling injection tube; A piston rod, wherein the bottom end of the piston rod is fixedly connected to the top end of the compression plate, and the top end of the piston rod passes through the top end of the glue filling injection tube and is fixedly connected to a first U-shaped driving plate, wherein the first U-shaped driving plate is slidably connected to the side wall of the U-shaped flip frame, and driving inclined grooves are provided on both sides of the first U-shaped driving plate; Two gas springs, the two gas springs are symmetrically fixedly connected to the side walls of the U-shaped flip frame, the ends of the telescopic ends of the two gas springs are commonly fixedly connected to a push plate, the two sides of the push plate are symmetrically fixedly connected to a first connecting pin, and the first connecting pin is slidably connected in the driving inclined slot; A first one-way valve, wherein the first one-way valve is arranged in the glue filling port; A glue storage tank, the glue storage tank is fixedly connected to the outer side wall of the U-shaped turning frame, the bottom end of the glue storage tank is fixedly connected to a glue replenishing tube, the other end of the glue replenishing tube is fixedly connected to a glue replenishing injection tube, and a second one-way valve is arranged in the glue replenishing tube; Specifically, by providing a first U-shaped driving plate and a pushing plate, during the turning process of the U-shaped turning frame, the pushing plate approaches the side wall of the expansion capsule, and is squeezed by the side wall of the expansion capsule, so that the pushing plate moves toward the side wall of the U-shaped turning frame. During the movement of the pushing plate, the first connecting pin slides along the driving inclined groove, and the U-shaped driving plate moves downward under the drive of the driving inclined groove, so that the piston rod pushes the compression plate to move downward, so that the glue in the glue filling injection tube is discharged through the glue filling port; Since the expansion capsule is adapted and adjusted according to the size of the mesh, when the mesh size is larger, the expansion capsule size is larger, so that the pushing plate moves farther, so that the compression plate moves downward farther, and more glue is squeezed out, and vice versa. Therefore, the glue injection tube can spray a specified amount of glue according to the size of the mesh, which is conducive to the glue being able to fully fill the mesh, and on the other hand, it reduces the glue from contaminating the surrounding meshes and causing the surrounding meshes to be blocked by glue. In addition, by arranging a gas spring, a first one-way valve and a second one-way valve, during the process of the U-shaped flip frame flipping and resetting, under the action of the gas spring, the push plate is reset, the U-shaped driving plate drives the compression plate to reset, and the glue in the glue storage tank is extracted through the glue replenishing tube, thereby replenishing the glue in the glue replenishing injection tube.

[0009] In addition, to solve the above problems, the present invention also proposes a precise laser steel mesh hole filling method, which also includes a controller; The laser steel mesh hole filling method specifically includes: The controller receives first request information sent by the pressure sensor, where the first request information is generated when a pressure value acquired by the pressure sensor increases linearly; The controller generates first control information based on the first request information, wherein the first control information is used to start the induction electromagnetic block so that the induction electromagnetic block generates magnetic force; The controller sends the first control information to the induction electromagnetic block, so that the induction electromagnetic block generates magnetic force and magnetically adsorbs the U-shaped metal strip, so that the installation shell is positioned to locate the position of the glue injection tube; The controller receives a second request message sent by the pressure sensor, where the second request message is generated when the pressure value acquired by the pressure sensor decreases and returns to an initial value; The controller generates second control information based on the second request information, wherein the second control information is used to turn off the induction electromagnetic block so that the magnetic force of the induction electromagnetic block disappears; The controller sends the second control information to the induction electromagnetic block, so that the magnetic force of the induction electromagnetic block disappears, and the positioning adsorption with the U-shaped metal strip is cancelled, so that the induction electromagnetic block can slide freely in the T-shaped slide groove; The controller generates first control information after receiving the first request information sent by the pressure sensor, and then sends the first control information to the induction electromagnetic block, so that the induction electromagnetic block generates magnetic force and magnetically adsorbs the U-shaped metal strip, so that the installation shell is positioned to position the glue injection tube, so that the central axis of the glue filling port coincides with the vertical line of the center point of the expansion capsule after the U-shaped flip frame rotates, thereby reducing the occurrence of glue leakage; After receiving the second request information sent by the pressure sensor, the controller generates second control information, and then sends the second control information to the induction electromagnetic block, so that the magnetic force of the induction electromagnetic block disappears, the positioning adsorption with the U-shaped metal strip is cancelled, and the induction electromagnetic block can slide freely in the T-shaped slide groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides an expansion capsule, a U-shaped flip frame and a glue filling injection tube. The expansion of the expansion capsule and the squeezing and pushing of the inner wall of the mesh make the mounting shell move to the accurate position, so that the central axis of the glue filling port after flipping coincides with the vertical line of the center point of the mesh. On the one hand, it is beneficial to fully fill the mesh, and on the other hand, it is beneficial to reduce the occurrence of glue leakage, avoid glue contamination of the surrounding mesh, and prevent the mesh at other positions from being blocked by glue.

[0011] 2. The present invention provides an induction electromagnetic block and a U-shaped metal strip. When the expansion capsule is blocked by the side wall of the mesh and no longer expands, the induction electromagnetic block generates magnetic force and is magnetically adsorbed to the U-shaped metal strip, so that the mounting shell is positioned to position the glue filling injection tube and improve stability during the glue filling process.

[0012] 3. The present invention sets a first U-shaped driving plate and a pushing plate. During the flipping process of the U-shaped flip frame, the pushing plate approaches the side wall of the expansion capsule and is squeezed by the side wall of the expansion capsule. Since the expansion capsule is adapted and adjusted according to the size of the mesh, the larger the mesh size and the larger the size of the expansion capsule, the farther the pushing plate moves, and thus the greater the distance the compression plate moves downward, the more glue is squeezed out, and vice versa. Therefore, the glue filling injection tube can spray a specified amount of glue according to the size of the mesh. On the one hand, it is beneficial for the glue to fully fill the mesh, and on the other hand, it reduces the glue contamination of the surrounding meshes, causing the surrounding meshes to be blocked by glue.

DETAILED DESCRIPTION

[0015] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0016] like Figures 2 to 13 A precise laser steel mesh hole filling device is shown, comprising: Positioning platform 1, positioning platform 1 is used to position the laser steel mesh 3; A driving block 6, the top of which is slidably connected to the top of the positioning platform 1, the bottom of which is fixedly connected to a cylinder 7, the bottom of which is fixedly connected to a mounting block 8, and a T-shaped slide groove 801 is provided at the bottom of the mounting block 8; The slider 9 is slidably connected in the T-shaped slide groove 801. The bottom of the slider 9 is fixedly connected to a mounting shell 10. The inner wall of the mounting shell 10 is slidably connected to a connecting rod assembly. The bottom end of the connecting rod assembly is provided with an expansion capsule 18. A U-shaped flip frame 20, the top of which is rotatably connected to the side wall of the bottom end of the mounting shell 10, a glue filling injection tube 21 is fixedly connected to the bottom end of the U-shaped flip frame 20, and a glue filling port 2101 is provided at the bottom end of the glue filling injection tube 21 to inject glue into the mesh; A lifting and adjusting component, which is used to lift and adjust the connecting rod component to adjust the distance between the expansion capsule 18 and the mesh; A flip driving assembly, which is used to drive the U-shaped flip frame 20 to rotate so that the central axis of the glue filling port 2101 coincides with the vertical line of the center point of the expansion capsule 18; Specifically, in the prior art, during the process of glue filling for the laser steel mesh 3, due to the small size of the mesh, it is difficult for the glue filling mechanism to accurately move to the center of the mesh, which easily causes glue leakage. On the one hand, it is not conducive to fully filling the mesh, and on the other hand, it is easy to contaminate the surrounding meshes, thereby causing the meshes at other positions to be blocked by glue. The technical solution can solve the above problems. The specific operation is as follows: first, a patch is attached to the bottom of the position where the laser steel mesh 3 needs to be glued to prevent leakage during glue filling, and then the laser steel mesh 3 is placed on the positioning platform 1. The laser steel mesh 3 is positioned by the positioning platform 1. The positioning can be performed by inserting the positioning pins into the frame of the laser steel mesh 3, or by other methods. Positioning the laser steel mesh 3 keeps the laser steel mesh 3 stable during the glue filling process; After positioning is completed, the mounting shell 10 is adjusted and moved close to the position where glue needs to be added by adjusting the driving block 6, so that the expansion capsule 18 moves to the top of the mesh, and then the cylinder 7 is started to move the telescopic rod of the cylinder 7 downward, so that the expansion capsule 18 is inserted into the mesh. At this time, the expansion capsule 18 is in a contracted state to facilitate insertion into the mesh, and the bottom of the limit plate 19 contacts the top surface of the laser steel mesh 3; After the expansion capsule 18 is inserted into the mesh, the expansion capsule 18 expands. Due to the limiting effect of the limiting plate 19, the expansion capsule 18 expands toward the side wall of the mesh and eventually fills the mesh. During the expansion of the expansion capsule 18, it contacts and squeezes the inner wall of the mesh. The expansion capsule 18 is pushed by the squeezing force, so that the mounting shell 10 drives the slider 9 to slide along the T-shaped slide groove 801, and finally the center of the expansion capsule 18 coincides with the center of the mesh. Then, the lifting and adjusting assembly is activated to move the expansion capsule 18 upward and away from the mesh to make way for the U-shaped turning frame 20 to turn over; Then, the flipping drive assembly is started to rotate the U-shaped flipping frame 20 so that the glue filling injection tube 21 is vertically located above the laser steel mesh 3. At this time, the central axis of the glue filling port 2101 coincides with the vertical line of the center point of the expansion capsule 18, so that the glue filling port 2101 is located directly above the center position of the mesh. Finally, glue is injected into the mesh through the glue filling injection tube 21, so that the glue enters the mesh and diffuses to the periphery from the center position of the mesh, and finally fills the mesh. On the one hand, it is beneficial to fully fill the mesh, and on the other hand, it is beneficial to reduce the occurrence of glue leakage, avoid glue contaminating the surrounding meshes, and cause the meshes at other positions to be blocked by glue.

[0017] The specific implementation process also includes: Two first guide rails 4, the two first guide rails 4 are symmetrically fixedly connected to the top of the positioning platform 1, a first screw rod is rotatably connected inside the first guide rail 4, a first motor is fixedly connected to the end of the first guide rail 4, and an output shaft end of the first motor is fixedly connected to the first screw rod; The two first guide rails 4 are slidably connected with a second guide rail 5, the second guide rail 5 is threadedly connected to the first screw rod, the second guide rail 5 is rotatably connected with a second screw rod, the end of the second guide rail 5 is fixedly connected with a second motor, the end of the output shaft of the second motor is fixedly connected to the second screw rod, the driving block 6 is slidably connected to the second guide rail 5, and the driving block 6 is threadedly connected to the second screw rod; The second guide rail 5 moves in the X direction along the first guide rail 4, and the driving block 6 moves in the Y direction along the second guide rail 5; Specifically, by setting the first guide rail 4 and the second guide rail 5, the driving block 6 is preliminarily adjusted to move, so that the driving block 6 drives the expansion capsule 18 to move to the mesh position, and then through the above operation, the expansion capsule 18 is adjusted to move, so that the center of the expansion capsule 18 coincides with the center of the mesh, so that the central axis of the glue filling port 2101 after flipping adjustment coincides with the vertical line of the center point of the expansion capsule 18, so that the glue filling port 2101 is located directly above the center position of the mesh, which is beneficial to reduce the occurrence of glue leakage.

[0018] In the specific implementation process, a sticky film can be attached to the outer surface of the expansion capsule 18 so that the expansion capsule 18 can clean the dust on the inner wall of the mesh when it is separated from the mesh, thereby facilitating full contact between the glue and the inner wall of the mesh.

[0019] As a further embodiment of the present invention, it also includes: The connecting rod assembly includes: A sliding block 11, the sliding block 11 is slidably connected to the inner wall of the mounting shell 10; A rotating shaft 13, the rotating shaft 13 is rotatably connected to the inner wall of the sliding block 11; A mounting rod 14, the top end of which is slidably inserted into the inner wall of the rotating shaft 13; Cavity 1401, which is formed on the inner wall of the bottom end of the mounting rod 14, and the expansion capsule 18 is fixedly connected to the outer wall of the bottom end of the mounting rod 14 and communicates with the cavity 1401; The annular shell 16 is rotatably connected to the outer wall of the mounting rod 14 at a position corresponding to the cavity 1401; A plurality of air holes 1402 are provided on the outer wall of the mounting rod 14 corresponding to the positions of the annular shell 16; A ventilation hose 17, one end of which is fixedly connected to the annular shell 16, and the other end of which is fixedly connected to an external air pump; Specifically, by providing the mounting rod 14, the cavity 1401 and the annular shell 16, after the expansion capsule 18 is inserted into the mesh, gas is injected into the ventilation hose 17 through the outer air pump, and the gas enters the annular shell 16 through the guidance of the ventilation hose 17, and then enters the cavity 1401 through the air hole 1402. Since the expansion capsule 18 is connected to the cavity 1401, as the gas enters, the expansion capsule 18 gradually expands and finally fills the mesh; After waiting for the mesh hole repair to be completed, the gas in the cavity 1401 is extracted by an external air pump to shrink the expansion capsule 18, thereby preparing for the next glue repair.

[0020] As a further embodiment of the present invention, it also includes: The driving motor 12 is fixedly connected to the top of the sliding block 11, the output shaft of the driving motor 12 is fixedly connected to the rotating shaft 13, and the bottom end of the expansion capsule 18 is provided with a polished surface 1801; Specifically, by setting the driving motor 12 and the polishing surface 1801, after the glue in the mesh is solidified, the flip driving component is started to rotate the U-shaped flip frame 20, so that the glue injection tube 21 is away from the mesh, and then the expansion capsule 18 is moved downward by the lifting and adjusting component, so that the bottom surface of the expansion capsule 18 is in contact with the glue surface, and the installation rod 14 is squeezed by the glue surface to slide upward along the rotating shaft 13, and then the driving motor 12 is started, so that the rotating shaft 13 drives the installation rod 14 to rotate, and the expansion capsule 18 rotates, so that the polishing surface 1801 at the bottom of the expansion capsule 18 polishes the glue surface, so as to improve the flatness of the glue filling area; And because the size of the expansion capsule 18 is adapted according to the mesh, the polishing surface 1801 is adapted to the glue surface to avoid damaging the surrounding mesh due to polishing.

[0021] As a further embodiment of the present invention, it also includes: The pressure sensor 15 is fixedly connected to the top wall of the cavity 1401; The slider 9 is an induction electromagnetic block, and the inner wall of the T-shaped slide groove 801 is fixedly connected with a U-shaped metal strip 802; Specifically, by setting the pressure sensor 15, after the expansion capsule 18 fully fills the mesh, the gas is continuously injected into the cavity 1401. At this time, the expansion capsule 18 is blocked by the side wall of the mesh and no longer expands, so that a sealed space is formed between the cavity 1401 and the expansion capsule 18. During the process of gas injection into the space, the pressure in the cavity 1401 increases linearly. The pressure change information is detected by the pressure sensor 15. Based on the detected pressure change information, the induction electromagnetic block and the external air pump are distributed and started, so that the induction electromagnetic block generates magnetic force and is magnetically adsorbed with the U-shaped metal strip 802, so that the mounting shell 10 is positioned to position the glue injection tube 21 and improve the stability during the glue filling process. The external air pump is turned off and the injection of gas into the cavity 1401 is stopped, which is conducive to stabilizing the shape of the expansion capsule 18 after it leaves the mesh and preventing the expansion capsule 18 from further expanding. After the glue filling is completed, the external air pump is controlled to extract the gas in the expansion capsule 18, so that the expansion capsule 18 shrinks. After the expansion capsule 18 shrinks, the pressure in the cavity 1401 decreases and returns to the initial value. The initial pressure value is detected by the pressure sensor 15, so that the magnetic force of the induction electromagnetic block disappears, and the induction electromagnetic block cancels the positioning and adsorption with the U-shaped metal strip 802, so that the induction electromagnetic block can slide freely in the T-shaped slide groove 801, preparing for the next adjustment.

[0022] As a further embodiment of the present invention, it also includes: A compression plate 22, the compression plate 22 is slidably connected to the inner wall of the glue filling injection tube 21; The piston rod 23, the bottom end of the piston rod 23 is fixedly connected to the top end of the compression plate 22, the top end of the piston rod 23 passes through the top end of the glue injection tube 21 and is fixedly connected to the first U-shaped driving plate 24, the first U-shaped driving plate 24 is slidably connected to the side wall of the U-shaped flip frame 20, and driving inclined grooves 2401 are opened on both sides of the first U-shaped driving plate 24; Two gas springs 25, the two gas springs 25 are symmetrically fixedly connected to the side wall of the U-shaped flip frame 20, the ends of the telescopic ends of the two gas springs 25 are commonly fixedly connected to a push plate 26, and the two sides of the push plate 26 are symmetrically fixedly connected to a first connecting pin 2601, and the first connecting pin 2601 is slidably connected in the driving inclined slot 2401; A first one-way valve, which is disposed in the glue filling port 2101; The glue storage tank 28 is fixedly connected to the outer wall of the U-shaped turning frame 20. The bottom end of the glue storage tank 28 is fixedly connected to a glue supply pipe 27. The other end of the glue supply pipe 27 is fixedly connected to the glue supply injection pipe 21. A second one-way valve is arranged in the glue supply pipe 27. Specifically, by providing the first U-shaped driving plate 24 and the pushing plate 26, during the turning process of the U-shaped turning frame 20, the pushing plate 26 approaches the side wall of the expansion capsule 18, and is squeezed by the side wall of the expansion capsule 18, so that the pushing plate 26 moves toward the side wall of the U-shaped turning frame 20. During the movement of the pushing plate 26, the first connecting pin 2601 slides along the driving inclined groove 2401, and driven by the driving inclined groove 2401, the U-shaped driving plate moves downward, so that the piston rod 23 pushes the compression plate 22 to move downward, so that the glue in the glue filling injection tube 21 is discharged through the glue filling port 2101; Since the expansion capsule 18 is adapted and adjusted according to the size of the mesh, when the mesh size is larger, the expansion capsule 18 is larger, so that the push plate 26 moves farther, so that the compression plate 22 moves downward a greater distance, more glue is squeezed out, and vice versa, so that the glue injection tube 21 can spray a specified amount of glue according to the size of the mesh, which is conducive to the glue being able to fully fill the mesh, and on the other hand, reduces the glue from contaminating the surrounding meshes, causing the surrounding meshes to be blocked by glue. In addition, by providing a gas spring 25, a first one-way valve and a second one-way valve, during the process of the U-shaped flip frame 20 flipping and resetting, under the action of the gas spring 25, the push plate 26 is reset, and the U-shaped drive plate drives the compression plate 22 to reset, and the glue in the glue storage tank 28 is extracted through the glue replenishing tube 27, thereby replenishing the glue in the glue replenishing injection tube 21.

During the movement, the second connecting pin 1101 is driven by the first inclined groove to move the second connecting pin 1101 upward, so that the sliding block 11 drives the mounting rod 14 and the expansion capsule 18 to move upward to make way for the flipping of the U-shaped flip frame 20, and then the first connecting pin 2601 enters the first straight groove, and the first connecting pin 2601 is supported by the first straight groove, so that the mounting rod 14 is located at the specified position.

[0024] As a further embodiment of the present invention, the flip drive assembly comprises: A U-shaped driving frame 31 is slidably connected to the side wall of the bottom end of the mounting shell 10. The U-shaped driving frame 31 is symmetrically provided with transverse grooves 3101 on both sides. A connecting block is slidably connected in the transverse groove 3101. A third connecting pin 3102 is rotatably connected in the connecting block. The third connecting pin 3102 is fixedly connected to the side wall of the top end of the U-shaped flip frame 20. The mounting plate 32 is fixedly connected to the side wall of the U-shaped driving frame 31. The side wall of the mounting plate 32 is provided with a second driving groove 3201. The second driving groove 3201 has a second straight groove and a second inclined groove. A fourth connecting pin 2902 is slidably connected in the second driving groove 3201. The fourth connecting pin 2902 is fixedly connected to the side wall of the second U-shaped driving plate 29; Specifically, by setting a U-shaped driving frame 31 and a mounting plate 32, when the second connecting pin 1101 moves along the first oblique groove, the fourth connecting pin 2902 moves along the second straight groove. When the second connecting pin 1101 enters the first straight groove and moves along the first straight groove, the fourth connecting pin 2902 moves along the second oblique groove.

The sliders 9 are slidably connected in the arc-shaped limiting grooves to limit the rotation trajectory of the U-shaped flip frame 20.

[0026] It should be noted that the lifting and adjusting component can also be lifted and adjusted by driving the sliding block 11 through the lifting cylinder, and the flipping drive component can also drive the U-shaped flipping frame 20 to rotate by a motor, but it is necessary to control the starting sequence of the lifting and adjusting component and the flipping drive component, that is, the mounting rod 14 and the expansion capsule 18 must give way first, and then the U-shaped flipping frame 20 can be rotated.

[0027] In addition, refer to Figure 1 , Fig.14 and Fig.15 , To solve the above problems, the present invention also proposes a precise laser steel mesh hole filling method, which also includes a controller 2; The laser steel mesh 3 hole filling method specifically includes: The controller 2 receives the first request information sent by the pressure sensor 15, where the first request information is generated when the pressure value acquired by the pressure sensor 15 increases linearly; The controller 2 generates first control information based on the first request information, and the first control information is used to start the induction electromagnetic block so that the induction electromagnetic block generates magnetic force; The controller 2 sends the first control information to the induction electromagnetic block, so that the induction electromagnetic block generates magnetic force and magnetically adsorbs the U-shaped metal strip 802, so that the installation shell 10 is positioned to locate the position of the glue injection tube 21; The controller 2 receives the second request information sent by the pressure sensor 15, and the second request information is generated when the pressure value acquired by the pressure sensor 15 decreases and returns to the initial value; The controller 2 generates second control information based on the second request information, and the second control information is used to turn off the induction electromagnetic block to make the magnetic force of the induction electromagnetic block disappear; The controller 2 sends the second control information to the induction electromagnetic block, so that the magnetic force of the induction electromagnetic block disappears, and the positioning adsorption with the U-shaped metal strip 802 is cancelled, so that the induction electromagnetic block can slide freely in the T-shaped slide groove 801; The controller 2 generates the first control information after receiving the first request information sent by the pressure sensor 15, and then sends the first control information to the induction electromagnetic block, so that the induction electromagnetic block generates magnetic force and magnetically adsorbs the U-shaped metal strip 802, so that the mounting shell 10 is positioned to position the glue injection tube 21, so that the central axis of the glue filling port 2101 coincides with the vertical line of the center point of the expansion capsule 18 after the U-shaped flip frame 20 rotates, thereby reducing the occurrence of glue leakage; After receiving the second request information sent by the pressure sensor 15, the controller 2 generates the second control information, and then sends the second control information to the induction electromagnetic block, so that the magnetic force of the induction electromagnetic block disappears, canceling the positioning adsorption with the U-shaped metal strip 802, so that the induction electromagnetic block can slide freely in the T-shaped slide groove 801.

[0028] Specifically, the specific method of using the pressure sensor 15 includes: The pressure sensor 15 obtains the pressure value in the cavity 1401. When the pressure value increases linearly, the pressure sensor 15 generates first request information. The pressure sensor 15 sends the first request information to the controller 2 to request the controller 2 to control the induction electromagnetic block to start, so that the induction electromagnetic block generates magnetic force; The pressure sensor 15 obtains the pressure value given by the piston plate, and when the pressure value decreases and returns to the initial value, the pressure sensor 15 generates a second request information; The pressure sensor 15 sends the second request information to the controller 2 to request the controller 2 to control the induction electromagnetic block to be turned off so that the magnetic force of the induction electromagnetic block disappears; After the expansion capsule 18 fully fills the mesh, the gas is continuously injected into the cavity 1401. At this time, the expansion capsule 18 is blocked by the side wall of the mesh and no longer expands, so that a sealed space is formed between the cavity 1401 and the expansion capsule 18. During the process of gas injection into the space, the pressure in the cavity 1401 increases linearly. When the pressure value obtained by the pressure sensor 15 increases linearly, the first request information is generated and the first request information is sent to the controller 2. After the glue filling is completed, the external air pump is controlled to extract the gas in the expansion capsule 18, so that the expansion capsule 18 shrinks. After the expansion capsule 18 shrinks, the pressure in the cavity 1401 decreases and returns to the initial value. When the pressure sensor 15 detects that the pressure in the cavity 1401 decreases and returns to the initial value, the pressure sensor 15 generates a second request information and sends the second request information to the controller 2. Specifically, the specific use method of the induction electromagnetic block includes: The induction electromagnetic block receives the first control information sent by the controller 2; The induction electromagnetic block is activated based on the first control information to generate magnetic force, and the induction electromagnetic block and the U-shaped metal strip 802 are magnetically adsorbed to locate the position of the glue injection tube 21; The induction electromagnetic block receives the second control information sent by the controller 2; The induction electromagnetic block is turned off based on the second control information, the magnetic force disappears, and the induction electromagnetic block cancels the positioning adsorption with the U-shaped metal strip 802, so that the induction electromagnetic block can slide freely in the T-shaped slide groove 801; The induction electromagnetic block is activated after receiving the first control information sent by the controller 2, and generates magnetic force. The induction electromagnetic block and the U-shaped metal strip 802 are magnetically adsorbed to locate the position of the glue injection tube 21, so that the central axis of the glue filling port 2101 coincides with the vertical line of the center point of the expansion capsule 18 after the U-shaped flip frame 20 rotates, thereby reducing the occurrence of glue leakage; After receiving the second control information sent by the controller 2 , the induction electromagnetic block is turned off, the magnetic force disappears, and the positioning adsorption with the U-shaped metal strip 802 is cancelled, so that the induction electromagnetic block can slide freely in the T-shaped slide groove 801 .

[0029] Working principle of the present invention: firstly, a patch is attached to the bottom of the position where the laser steel mesh 3 needs to be glued to prevent leakage during glue filling, and then the laser steel mesh 3 is placed on the positioning platform 1. The laser steel mesh 3 is positioned by the positioning platform 1. The positioning can be performed by inserting the positioning pins with the frame of the laser steel mesh 3, or by other methods, so that the laser steel mesh 3 can be kept stable during the glue filling process; After positioning is completed, the mounting shell 10 is adjusted and moved close to the position where glue needs to be added by adjusting the driving block 6, so that the expansion capsule 18 moves to the top of the mesh, and then the cylinder 7 is started to move the telescopic rod of the cylinder 7 downward, so that the expansion capsule 18 is inserted into the mesh. At this time, the expansion capsule 18 is in a contracted state to facilitate insertion into the mesh, and the bottom of the limit plate 19 contacts the top surface of the laser steel mesh 3; After the expansion capsule 18 is inserted into the mesh, the expansion capsule 18 expands. Due to the limiting effect of the limiting plate 19, the expansion capsule 18 expands toward the side wall of the mesh and eventually fills the mesh. During the expansion of the expansion capsule 18, it contacts and squeezes the inner wall of the mesh. The expansion capsule 18 is pushed by the squeezing force, so that the mounting shell 10 drives the slider 9 to slide along the T-shaped slide groove 801, and finally the center of the expansion capsule 18 coincides with the center of the mesh. Then, the lifting and adjusting assembly is activated to move the expansion capsule 18 upward and away from the mesh to make way for the U-shaped turning frame 20 to turn over; Then start the flipping drive assembly to rotate the U-shaped flipping frame 20 so that the glue filling injection tube 21 is vertically located directly above the laser steel mesh 3. At this time, the central axis of the glue filling port 2101 coincides with the vertical line of the center point of the expansion capsule 18, so that the glue filling port 2101 is located directly above the center position of the mesh. Finally, glue is injected into the mesh through the glue filling injection tube 21, so that the glue enters the mesh and diffuses to the periphery from the center position of the mesh, and finally fills the mesh.
