[0062] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0063] Embodiment:

[0064] As Figure 1 shown, the embodiment of the present application discloses a manual solder paste brushing device for batch brushing solder paste on aluminum substrates in a rectifier bridge. Its specific structure includes: a base 1, a three-dimensional adjustment platform 2, a rotating shaft 3, a lifting mechanism 4, and a clamping mechanism 5.

[0065] It should be noted that a positioning groove adapted to the aluminum substrate is provided on the top surface of the positioning plate 1A, so that a plurality of aluminum substrates can be limited and arranged in a rectangular array on the top surface of the positioning plate 1A; among them, different types of aluminum substrates are adapted to different positioning plates 1A.

[0066] It can be understood that the silk screen stencil 1B includes a mesh sheet and a rectangular frame. The mesh sheet is clamped in the rectangular frame, and hollow holes are provided thereon. The shape and position of the hollow holes correspond one by one to the welding areas of the aluminum substrates arranged on the positioning plate 1A.

[0067] One side of the base 1 has a convex platform, and the top surface of the convex platform is used to arrange the lifting mechanism 4, so as to improve the structural compactness of the device.

[0068] The three-dimensional adjustment platform 2 is installed on the top surface of the base 1 for placing the positioning plate 1A. It can be precisely adjusted on three axes, namely the X, Y, and Z axes, so as to precisely adjust the position of the positioning plate 1A and make it aligned with the covered silk screen stencil 1B.

[0069] The rotating shaft 3 is horizontally arranged and is located beside the three-dimensional adjustment platform 2, and is used to support the clamping mechanism 5, so that the silk screen stencil 1B can be flipped.

[0070] The lifting mechanism 4 is arranged on the top surface of the base 1, and its driving end is connected to the rotating shaft 3, and is used to adjust the height of the rotating shaft 3, so that the mesh sheet is fully attached to the aluminum substrate, and is used to adapt to aluminum substrates of different thicknesses.

[0071] The clamping mechanism 5 is installed on the rotating shaft 3 and is used to clamp and fix the silk screen stencil 1B, so that the silk screen stencil 1B can be flip-covered on the positioning plate 1A.

[0072] During debugging, place the positioning plate 1A on the three-dimensional adjustment platform 2, clamp and fix the corresponding silk screen stencil 1B on the clamping mechanism 5, then drive the rotating shaft 3 to rotate, so that the silk screen stencil 1B is flipped and covered on the positioning plate 1A, then adjust the three-dimensional adjustment platform 2 to make the positioning plate 1A aligned with the silk screen stencil 1B, and finally finely adjust the lifting mechanism 4 to make the mesh sheet fully attached to the aluminum substrate.

[0073] During operation, the screen printing stencil 1B is flipped and covered on the positioning plate 1A, and then solder paste is brushed on the top surface of the mesh sheet. Thus, the operation of applying solder paste to multiple aluminum substrates arranged on the top surface of the positioning plate 1A can be carried out. After completion, the screen printing stencil 1B is flipped, and then a new positioning plate 1A is replaced to perform the next operation.

[0074] By setting the clamping mechanism 5 in the present utility model, the screen printing stencil 1B can be disassembled and replaced. By setting the three-dimensional adjustment platform 2, the position of the positioning plate 1A can be adjusted so that it is fully aligned with the screen printing stencil 1B. Then, through the lifting mechanism 4, the screen printing stencil 1B is in a horizontal state after being covered, thereby ensuring that the mesh sheet is fully attached to the aluminum substrate. In this way, by replacing the positioning plate 1A and the screen printing stencil 1B, aluminum substrates with different structural forms can be used, improving the versatility, meeting the diverse needs in production, facilitating practical application, and reducing the procurement and maintenance costs.

[0075] In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 and Figures 6 - 8 shown, the lifting mechanism 4 includes: two lifting components 41, which are respectively arranged at both ends of the rotating shaft 3, and the driving ends are rotationally connected to the ends of the rotating shaft 3.

[0076] By setting two lifting components 41, the rotating shaft 3 can be supported at both ends, thereby reducing stress concentration, increasing the load-bearing capacity, and improving the structural stability.

[0077] On the basis of the above embodiments, as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 shown, the lifting component 41 includes: a threaded rod 411, two limiting blocks 412 and a support block 413.

[0078] Specifically, the threaded rod 411 is vertically installed on the top surface of the base 1, and an end sleeve is fixedly sleeved on the top of the threaded rod 411, which plays a role of limiting and blocking to prevent the limiting block 412 from detaching.

[0079] Specifically, the two limiting blocks 412 are threadedly connected to the threaded rod 411. The limiting block 412 has an annular structure, and a mesh thread is provided on the outer periphery, increasing the friction force and facilitating the rotation and adjustment by the operator.

[0080] Specifically, the support block 413 is movably sleeved on the threaded rod 411 and is located between the two limiting blocks 412, and is rotationally connected to the end of the rotating shaft 3. The support block 413 has a rectangular parallelepiped structure, so that the upper and lower surfaces are fully attached to the limiting block 412, improving the structural stability.

[0081] During adjustment, by rotating the two limit blocks 412, they can be moved up and down along the threaded rod 411, so as to clamp and limit the support block 413 at an appropriate height, making the support block 413 fixed.

[0082] Through the above structural design of the lifting assembly 41, the height of the rotating shaft 3 can be adjusted conveniently and quickly, and the structure has good stability, high load-bearing capacity, simple structure, and is convenient for production and manufacturing.

[0083] Based on the above embodiments, as Figure 4 and Figure 5 shown, it further includes: a limit assembly 6, which is used to limit the flipping angle of the screen printing stencil 1B, preferably arranged at both ends of the rotating shaft 3 respectively, having the advantage of high structural stability, but can also be arranged at only one end, without specific limitation.

[0084] Exemplarily, as Figures 5 - 8 shown, the limit assembly 6 includes: a sleeve 61, a first bolt 62 and a limit rod 63. Among them, the sleeve 61 is in the shape of a circular tube and is movably sleeved on the end of the rotating shaft 3; the first bolt 62 is threadedly connected to the sleeve 61, and the stud can pass through the sleeve 61 and abut against the outer periphery of the rotating shaft 3; the limit rod 63 is arranged on the driving end of the lifting assembly 41 and can block the rotation of the first bolt 62.

[0085] When the screen printing stencil 1B is flipped to an appropriate angle, the first bolt 62 is blocked by the limit rod 63. At this time, the rotating shaft 3 and the sleeve 61 cannot rotate, making the screen printing stencil 1B fixed.

[0086] When adjusting the flipping angle of the screen printing stencil 1B, keep the first bolt 62 and the limit rod 63 in contact, then loosen the first bolt 62, and then flip the screen printing stencil 1B to drive the relative rotation of the rotating shaft 3 and the sleeve 61. After reaching the appropriate angle, tighten the first bolt 62 again to complete the adjustment.

[0087] The above structural design of the limit assembly 6 has the advantages of stable support, strong load-bearing capacity, and can conveniently and quickly adjust the flipping angle of the screen printing stencil 1B, which is convenient for operation and use.

[0088] In some embodiments, as Figures 1 - 4 shown, the clamping mechanism 5 includes: a clamping strip 51 and a plurality of locking members 52. Among them, the clamping strip 51 is arranged on the rotating shaft 3, and a clamping groove 511 is formed on one side; the plurality of locking members 52 are installed on the clamping strip 51 at intervals along the axis, and are used to clamp the return frame in the screen printing stencil 1B. It is set to four, but can also be less or more, without specific limitation.

[0089] Preferably, the cross-section of the clamping strip 51 is concave, which has the advantage of good regularity. By making the return frame in the screen printing stencil 1B fit with the bottom surface of the clamping groove 511, it also plays a role in calibration, ensuring that the positioning plate 1A can be aligned with the screen printing stencil 1B through position adjustment.

[0090] During use, one side of the return frame in the screen printing stencil 1B is inserted into the clamping groove 511 and kept in contact with its bottom surface, and then the return frame is clamped by each locking member 52 to complete the fixation.

[0091] Through the above structural design of the clamping mechanism 5, the return frame in the screen printing stencil 1B can be clamped and fixed. Its structure is simple and compact, facilitating production and manufacturing, and has stable support and is not easy to fall off.

[0092] Exemplarily, as Figure 1 shown, the locking member 52 includes: a fastening knob 521, a screw rod 522, and a pressing plate 523. Among them, the body of the screw rod 522 is threadedly connected to the clamping strip 51, and the top end is connected to the fastening knob 521, and the bottom end passes through the clamping strip 51 and extends into the clamping groove 511; the pressing plate 523 is installed at the bottom end of the screw rod 522.

[0093] During operation, the operator rotates the fastening knob 521, thereby driving the screw rod 522 to rotate together, so that it screws into the clamping groove 511. The screw rod 522 drives the pressing plate 523 to move, so that the pressing plate 523 presses against the top surface of the return frame.

[0094] The above structural design of the locking member 52 is convenient for the operator to operate, thereby improving the portability of use, and has a large contact area with the return frame and good clamping stability.

[0095] In this embodiment, as Figure 3 and Figures 6 - 8 shown, the clamping mechanism 5 further includes: a plurality of connecting blocks 53 and a plurality of second bolts 54. Among them, the plurality of connecting blocks 53 are arranged at intervals and are movably sleeved on the rotating shaft 3 and are all connected to the shown clamping strip 51; the plurality of second bolts 54 are threadedly connected to the connecting blocks 53 one by one, and the stud can pass through the connecting block 53 and abut against the outer periphery of the rotating shaft 3.

[0096] Exemplarily, the connecting blocks 53 and the second bolts 54 are provided in two and arranged on both sides of the rotating shaft 3, which ensures the connection stability and reduces the production cost, but can also be three, four or more, without specific limitation.

[0097] By tightening the second bolt 54, the connecting block 53 can be kept relatively fixed with the rotating shaft 3, so as to conveniently adjust the position of the clamping strip 51 in the axial direction of the rotating shaft 3 to meet diverse usage requirements.

[0098] In some embodiments, such as Figure 1 shown, it further includes: a handle 7 and a push rod 8; wherein, one end of the push rod 8 is connected to the handle 7, and the other end is connected to the rotating shaft 3.

[0099] When flipping the screen printing stencil 1B, the operator holds the handle 7, and then drives the rotating shaft 3 to rotate through the push rod 8, thereby driving the screen printing stencil 1B to flip.

[0100] Through the above design, it facilitates the flipping operation, is convenient for production use, improves the operation portability, and enhances the production efficiency.

[0101] In some embodiments, such as Figures 1 - 2 and Figures 7 - 8 shown, the three-dimensional adjustment platform 2 includes: a placement platform 21, a driving body 22, and three adjustment knobs 23; wherein, the top surface of the placement platform 21 has a plurality of mounting holes 211, and the mounting holes 211 are arranged in a matrix, with good regularity; the driving body 22 is installed on the top surface of the base 1 and is in transmission connection with the bottom surface of the placement platform 21; the three adjustment knobs 23 are arranged on the side surface of the driving body 22 and are used for precise adjustment on three axes (X, Y, Z axes).

[0102] It should be noted that a plurality of countersunk holes are formed on the positioning plate 1A. By inserting bolts into the countersunk holes and making the studs of the bolts inserted into the corresponding mounting holes 211, the positioning plate 1A can be limited and fixed, thereby ensuring the accuracy of solder paste printing.

[0103] It can be understood that the three-dimensional adjustment platform 2 belongs to the prior art. Therefore, the internal structure of the driving body 22 will not be described in detail, and as long as the above technical features are satisfied, it can be used without specific limitation.

[0104] When in use, the positioning plate 1A is limited and fixed on the top surface of the placement platform 21, and then by rotating the three adjustment knobs 23, the position of the placement platform 21 on three axes (X, Y, Z axes) can be adjusted, so as to conveniently and quickly align the positioning plate 1A with the screen printing stencil 1B.

[0105] Through the above design of the three-dimensional adjustment platform 2, the positioning plate 1A can be stably supported, ensuring the solder paste printing effect, and is also convenient for replacement, thereby improving the production efficiency.

[0106] In some embodiments, such as Figure 1 and Figure 6 shown, it further includes: a plurality of height-adjustable feet 9, which are installed around the bottom of the base 1.

[0107] Exemplarily, the height-adjustable feet 9 are set to four and are arranged at the four corners of the bottom surface of the base 1, and their support is stable; however, it is not limited thereto, and there may be fewer or more, without specific limitation.

[0108] By setting the height-adjustable foot pads 9, the device can be leveled, which is convenient for use in a working area with uneven ground and improves the use effect of the device.

[0109] In the description of the present utility model, a large number of specific details are illustrated. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.
