[0091] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0092] Example:

[0093] like Figure 1As shown, an embodiment of the present application discloses an automatic modular screen printing device for brushing solder paste on the welding area on the frame of a rectifier bridge, and its specific structure includes: a machine 1, a three-dimensional adjustment platform 2, a support plate 3, a lifting drive mechanism 4, a movable seat 5, a lateral drive mechanism 6, a support frame 7, two tin brushing assemblies 8, two clamping assemblies 9, two mounting plates 14, multiple guide rods 15 and two displacement sensors 16.

[0094] It should be noted that a jig plate is placed on the top surface of the positioning plate 1A, and the jig plate is limited by a plurality of positioning columns, and a plurality of positioning grooves adapted to the frames are provided on the top surface of the jig plate, so that a plurality of frames can be placed on the top surface of the jig plate in a front-to-back parallel manner; wherein frames of different structural forms are adapted to different jig plates.

[0095] It can be understood that the top surface of the screen printing screen 1B has multiple screen printing grooves, which are arranged side by side and spaced apart from each other, so that the scraper 81 can be inserted into them for left and right scraping; a hollow hole is opened at the bottom of the screen printing groove, and the shape and position of the hollow hole correspond one by one to the welding area of ​​the upper frame of the jig plate.

[0096] The machine 1 is a box-type structure with an internal cavity for accommodating and installing components; and one side has an inclined surface, on which an operation interface and control buttons are arranged for easy operation.

[0097] The three-dimensional adjustment platform 2 is installed on the top surface of the machine 1 and is used to place the positioning plate 1A; it can be precisely adjusted on three axes (X, Y, and Z axes) to accurately adjust the position of the positioning plate 1A so that the fixture plate placed on it can be aligned with the covered silk screen plate 1B.

[0098] The support plate 3 is arranged vertically and is located at the rear side of the three-dimensional adjustment platform 2; it serves as a support platform for installing other components to achieve modular production and assembly.

[0099] The lifting drive mechanism 4 is installed on the top surface of the machine platform 1, and the driving end is transmission-connected with the support plate 3, so as to drive the support plate 3 to move up and down.

[0100] The movable seat 5 is installed on the front side of the support plate 3 in a transverse sliding manner; the movable seat 5 can be displaced left and right on the support plate 3, thereby driving the components installed thereon to move transversely together.

[0101] The transverse driving mechanism 6 is installed on the supporting plate 3 , and the driving end is drivingly connected with the movable seat 5 , so as to drive the movable seat 5 to move left and right.

[0102] The support frame 7 is installed on the front side of the movable seat 5; the support frame 7 is used to support the tin brush assembly 8 so that the tin brush assembly 8 is in a suitable position above the screen printing screen plate 1B.

[0103] Two tin brushing assemblies 8 are installed on the left and right sides of the support frame 7, and are used to brush solder paste during the reciprocating process, thereby improving the screen printing efficiency.

[0104] Specifically, the tin brush assembly 8 includes a scraper 81 and a vertical drive unit 82; the vertical drive unit 82 is installed on the support frame 7 and is transmission-connected to the scraper 81 for driving the scraper 81 to move up and down.

[0105] The two clamping assemblies 9 are arranged on the left and right sides of the front side of the support plate 3 and are located below the tin brushing assembly 8 .

[0106] Specifically, the clamping assembly 9 includes: a clamping unit 91 and a transverse movement unit 92; wherein the clamping unit 91 is used to clamp and fix the screen printing screen 1B, and the transverse movement unit 92 is installed on the front side of the support plate 3 and is transmission-connected to the clamping unit 91 for adjusting the lateral position of the clamping unit 91.

[0107] Two displacement sensors 16 are installed on the left and right sides of the front of the support plate 3 in a lateral sliding manner and are located between the movable seat 5 and the support plate 3. The displacement sensor 16 is electrically connected to the controller, and the controller is used to control the opening and closing of the lateral drive mechanism 6 to adjust the distance of the left and right movement of the movable seat 5.

[0108] During debugging, the positioning plate 1A is placed on the three-dimensional adjustment platform 2, and the fixture plate is placed on the top surface of the positioning plate 1A, and then the corresponding screen printing screen 1B is clamped and fixed between the two clamping components 9, specifically, the lateral position of the clamping unit 91 is adjusted by the lateral movement unit 92, so that both the left and right ends of the screen printing screen 1B can be clamped by the clamping unit 91. Then, the lifting drive mechanism 4 is started to lower the support plate 3 until the screen printing screen 1B is covered on the fixture plate; then the three-dimensional adjustment platform 2 is adjusted to keep the fixture plate and the screen printing screen 1B aligned and fully fitted; finally, the positions of the two displacement sensors 16 are moved horizontally to adjust the first and last ends of the round trip of the scraper 81, so that the scraper 81 can fully brush the screen printing screens 1B of different lengths.

[0109] During operation, the frame is placed on the jig plate, and the jig plate is then placed on the positioning plate 1A. The support plate 3 is then driven down by the lifting drive mechanism 4 to fit the screen printing screen 1B to the jig plate. The vertical drive unit 82 is then started to drive the scraper 81 down until it is inserted into the screen printing slot. The horizontal drive mechanism 6 is then started to make the movable seat 5 move back and forth horizontally, thereby driving the scraper 81 to brush the bottom surface of the screen printing slot. When the movable seat 5 moves to block the displacement sensor 16 at the right end, it is determined that it has reached the end of the stroke, and then returns until it blocks the displacement sensor 16 at the left end. Finally, the lifting drive mechanism 4 drives the support plate 3 to rise and reset, so that the screen printing screen 1B is separated from the jig plate. At this time, the operator can take out the jig plate.

[0110] The utility model can adjust the lateral position of the clamping unit 91 by setting the lateral movement unit 92, and then the position of the displacement sensor 16 can be moved laterally to adjust the reciprocating stroke of the scraper 81, so as to adapt to screen printing screens 1B of different lengths. Then, the three-dimensional adjustment platform 2 can be used to adjust the position of the positioning plate 1A so that the fixture plate and the screen printing screen 1B are fully aligned. Therefore, by replacing the fixture plate and the screen printing screen 1B, frames of different structural forms can be used, thereby improving versatility, meeting diversified needs in production, being conducive to practical applications, and reducing procurement and maintenance costs.

[0111] In some embodiments, Figure 2 and Figure 4 As shown, in order to adjust the height of the scraper 81, the support frame 7 includes: a base plate 71, a support arm 72 and a first locking member 73. The base plate 71 is arranged vertically and installed on the front of the movable seat 5; the support arm 72 is arranged horizontally, and one end is vertically slidably connected to the base plate 71, and the other end is installed with a clamping assembly 9; the first locking member 73 is installed on the base plate 71 and is used to lock the support arm 72.

[0112] During adjustment, the support arm 72 is moved up and down to adjust the height of the scraper 81 so that it can fully fit with the screen printing groove when brushing solder paste, and then the substrate 71 and the adjusted support arm 72 can be locked and fixed by the first locking member 73 to ensure the use effect.

[0113] Preferably, the first locking member 73 is configured as a fastening bolt, and a handle is fixedly sleeved on the bolt head, which facilitates operation, but is not limited to this, and may also be other types of locking components without limitation.

[0114] Through the design of the support frame 7, the height of the scraper 81 can be adjusted quickly and conveniently, thereby ensuring that it can fully fit with the screen printing groove when brushing solder paste, thereby adapting to the use of screen printing stencils 1B of different thicknesses and improving versatility.

[0115] In some embodiments, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a movable groove 721 is formed on one side of the top surface of the support arm 72 away from the base plate 71 , and a horizontal plate 722 is installed on the top surface of the support arm 72 , and the horizontal plate 722 extends to above the movable groove 721 .

[0116] Through the above arrangement, a space is formed for the vertical drive unit 82 to move, thereby improving the structural compactness of the device and facilitating the installation and arrangement of the device.

[0125] It should be noted that by rotating the adjusting bolt 827, the distance between the scraper 81 and the support bar 826 can be adjusted, thereby adjusting the height of the scraper 81, which is used to fine-tune the position of the scraper 81 to ensure that the screen printing screen 1B can be fully brushed, thereby improving the use effect of the device.

[0126] When driven, the cylinder 822 drives the cross bar 821 to move up and down, and the cross bar 821 drives the scraper 81 to move up and down synchronously through the guide rod 823, the rotating shaft 824, the clamping block 825, the support bar 826 and the adjusting bolt 827; therefore, when the scraper 81 is needed to work, the scraper 81 is lowered to the surface of the screen, and when it is not needed to work, the scraper 81 is raised to above the screen printing screen 1B.

[0127] Through the above arrangement, the scraper 81 can be stably driven to move up and down, and its height and angle can be adjusted according to actual working conditions, thereby meeting diverse usage requirements and improving applicability.
