[0007] Furthermore, the jig platform assembly includes a jig platform; two groups of supporting platforms are fixedly connected to the bottom end of the inner wall of the jig platform, and a material discharge trough is provided between the two groups of supporting platforms.

[0009] Furthermore, a servo motor is embedded in the outer wall of the jig platform, and the output end of the servo motor is connected to a screw rod for transmission. A scraper is passed through the outer wall of the jig platform and is connected to the outer wall for horizontal sliding. The size of the scraper is smaller than the size of the positioning groove, and the scraper passes through the positioning groove. A linkage plate is fixedly connected to the end of the scraper and the side close to the screw rod, and the linkage plate is threadedly connected to the screw rod.

[0010] Furthermore, the support assembly includes a first horizontal plate; a second horizontal plate is provided at the bottom of the first horizontal plate, and an isolation plate is fixedly connected between the second horizontal plate and the first horizontal plate, and the isolation plate is located at the edge of the second horizontal plate and the first horizontal plate, and the first horizontal plate, the second horizontal plate and the isolation plate are spliced ​​together to form a U-shaped structure.

[0011] Furthermore, a plurality of groups of positioning guide rails are fixedly connected to the top of the first horizontal plate, and the number of the positioning guide rails is the same as the number of the guide slots, and the plurality of groups of positioning guide rails are all slidably fitted and connected to the inner wall of the guide slots.

[0012] Furthermore, the inner wall of the positioning guide rail is slidably connected with several groups of linkage blocks, the bottom ends of several groups of linkage blocks pass through the positioning guide rail and the first cross plate, and the bottom ends of several groups of linkage blocks extend to one side of the isolation plate.

[0013] Furthermore, a self-lowering inclined surface is provided on the top of the linkage block and on one side wall close to the positioning block, and the top end of the linkage block and the top end of the supporting platform are arranged at the same level.

[0014] Furthermore, a spring positioning cavity is provided at the bottom end of the linkage block, and a compression spring is provided on the inner wall of the spring positioning cavity. The top end of the compression spring is movably connected to the top end of the inner wall of the spring positioning cavity, and the bottom end of the compression spring is movably connected to the top of the second horizontal plate.

[0015] The beneficial effects of the present invention are:

[0016] 1. The integrated circuit board body and the steel mesh are connected to the top of the support assembly in a stacked state, and the output end of the second cylinder is used to push the positioning block to position the two ends of the integrated circuit board body and the steel mesh in the stacked state. In the process of the output end of the second cylinder continuously pushing the positioning block to move horizontally, the integrated circuit board body and the steel mesh are raised by the lifting slope, and finally the two ends of the integrated circuit board body and the steel mesh are movably connected to the inner wall of the limit groove, so that the integrated circuit board body, the steel mesh and the positioning groove are arranged at the same level, and then the output end of the first cylinder is used to push the positioning plate so that the positioning groove movably connects the other two ends of the integrated circuit board body and the steel mesh, which is used to align the position of the integrated circuit board body and the steel mesh in the stacked state during the solder paste printing stage to prevent printing deviation.

[0017] 2. The integrated circuit board body and the steel mesh can be placed horizontally by using several sets of linkage blocks on the top of the first horizontal plate. After placement, the integrated circuit board body and the steel mesh are synchronously and horizontally on the top of the supporting platform, and several sets of compression springs at the bottom of the isolation plate are used to improve the seismic resistance of the overall structure of the integrated circuit board body in the installation fixture to prevent damage to the integrated circuit board body structure.

[0018] 3. After the integrated circuit board body and the steel mesh are installed without manual stacking, the edges of the four surfaces of the connection between the integrated circuit board body and the steel mesh are in a flush state, which is convenient for applying solder paste to the upper surface of the steel mesh. The excess solder paste at the opening of the steel mesh surface is applied to the upper surface of the integrated circuit board body according to the position. After the integrated circuit board body and the steel mesh are positioned, the solder paste and the integrated circuit board body are installed.

[0019] 4. The output end of the first cylinder drives the positioning plate to slowly separate the positioning groove from the integrated circuit board body and the steel mesh. The output end of the servo motor is then used to drive the screw to rotate, so that the linkage plate threadedly connected to the screw drives the scraper to move horizontally. When the scraper passes through the positioning groove and approaches the connection between the integrated circuit board body and the steel mesh, it will eventually separate the integrated circuit board body and the steel mesh after solder paste printing, thereby improving the efficiency of sub-separation.

[0033] The embodiment of the present invention provides an integrated circuit board mounting fixture, including a fixture platform component 2; illustratively, as Figure 1 、 Figure 2 and Figure 3 shown.

[0037] The fixture platform assembly 2 includes a fixture platform 21; illustratively, as Figure 6 shown.

[0038] Two groups of supporting platforms 22 are fixedly connected to the bottom end of the inner wall of the jig platform 21, and a material discharge trough 23 is arranged between the two groups of supporting platforms 22. The outer walls of the two groups of supporting platforms 22 are provided with a receiving groove 24, and one end of the receiving groove 24 extends to the outer wall of the jig platform 21. The outer wall of the jig platform 21 is also provided with several groups of guide slides 25, and one end of several groups of guide slides 25 extends to the top of the inner wall of the receiving groove 24. A servo motor 26 is embedded in the outer wall of the jig platform 21, and the output end of the servo motor 26 is transmission-connected with a screw rod 27. A scraper 28 is passed through the outer wall of the jig platform 21 and is horizontally slidably connected. The size of the scraper 28 is smaller than the size of the positioning groove 4, and the scraper 28 passes through the positioning groove 4. A linkage plate 29 is fixedly connected to the end of the scraper 28 and the side close to the screw rod 27, and the linkage plate 29 is threadedly connected to the screw rod 27.

[0039] The support assembly 8 includes a first transverse plate 81; illustratively, as Figure 7 、 Figure 8 and Figure 9 shown.

[0040] A second transverse plate 82 is provided at the bottom of the first transverse plate 81, and an isolation plate 83 is fixedly connected between the second transverse plate 82 and the first transverse plate 81. The isolation plate 83 is located at the edge of the second transverse plate 82 and the first transverse plate 81, and the first transverse plate 81, the second transverse plate 82 and the isolation plate 83 are spliced ​​into a U-shaped structure. A plurality of groups of positioning guide rails 84 are fixedly connected to the top of the first transverse plate 81, and the number of the positioning guide rails 84 is the same as the number of the guide slots 25. The plurality of groups of positioning guide rails 84 are all slidably connected to the inner wall of the guide slots 25. The inner wall of the positioning guide rails 84 is slidably connected to a plurality of groups of linkage blocks 85. If The bottom ends of the linkage blocks 85 of the dry group all pass through the positioning guide rail 84 and the first cross plate 81, and the bottom ends of several groups of the linkage blocks 85 all extend to one side of the isolation plate 83. The top of the linkage block 85 and the side wall close to the positioning block 6 are provided with a self-lowering inclined surface 86. The top of the linkage block 85 is arranged at the same level as the top of the supporting platform 22. The bottom end of the linkage block 85 is provided with a spring positioning cavity 87, and the inner wall of the spring positioning cavity 87 is provided with a compression spring 88. The top end of the compression spring 88 is movably connected to the top of the inner wall of the spring positioning cavity 87, and the bottom end of the compression spring 88 is movably connected to the top of the second cross plate 82.

[0041] Specifically, the top of the first horizontal plate 81 utilizes a plurality of linkage blocks 85 to horizontally place the integrated circuit board body 9 and the steel mesh 10. After placement, the integrated circuit board body 9 and the steel mesh 10 are synchronously and horizontally positioned on the top of the supporting platform 22. The compression springs 88 at the bottom of the plurality of isolation plates 83 are used to enhance the shock resistance of the entire structure of the integrated circuit board body 9 in the installation fixture, thereby preventing damage to the integrated circuit board body structure.

[0042] The output end of the second air cylinder 5 pushes the positioning block 6 horizontally, causing the positioning block 6 to rise on both sides of the bottom of the integrated circuit board body 9. Finally, the two ends of the integrated circuit board body 9 and the steel mesh 10 are movably engaged with the inner wall of the limiting groove 12, so that the integrated circuit board body 9, the steel mesh 10 and the positioning groove 4 are arranged at the same level. Then, the output end of the first air cylinder 1 pushes the positioning plate 3, causing the positioning groove 4 to movably engage the other two ends of the integrated circuit board body 9 and the steel mesh 10, so as to align the positions of the stacked integrated circuit board body 9 and the steel mesh 10 during the solder paste printing stage.

[0043] After the integrated circuit board body 9 and the steel mesh 10 are installed without manual stacking, the edges of the four surfaces of the connection between the integrated circuit board body 9 and the steel mesh 10 are in a flush state, which facilitates the application of solder paste to the upper surface of the steel mesh 10. The excess solder paste at the opening of the surface of the steel mesh 10 is applied to the upper surface of the integrated circuit board body 9 according to the position, which is used for the installation of the solder paste and the integrated circuit board body 9 after the integrated circuit board body 9 and the steel mesh 10 are positioned;

[0044] The output end of the first cylinder 1 drives the positioning plate 3 to slowly separate the positioning groove 4 from the integrated circuit board body 9 and the steel mesh 10. Then, the output end of the servo motor 26 drives the screw rod 27 to rotate, so that the linkage plate 29 threadedly connected to the screw rod 27 drives the scraper 28 to move horizontally. When the scraper 28 passes through the positioning groove 4 and approaches the connection between the integrated circuit board body 9 and the steel mesh 10, the integrated circuit board body 9 and the steel mesh 10 after the solder paste is printed are finally separated from each other.

[0045] The scraper 28 is used to support the separated steel mesh 10, and the separated integrated circuit board body 9 will fall into the top of several groups of linkage blocks 85 to support and buffer the effect. The output end of the third cylinder 7 can also drive the isolation plate 83 to move horizontally, so that several groups of positioning guide rails 84, in the process of being stored in the guide chute 25, will again use the low end position of the self-lowering slope 86 to first contact the guide chute 25, and gradually squeeze the linkage block 85 downward through the guide chute 25, so that after all the groups of linkage blocks 85 are stored in the guide chute 25, the first cross plate 81, the second cross plate 82 and the isolation plate 83 are finally moved synchronously into the storage groove 24, so as to form the purpose of the integrated circuit board body 9 falling from the discharge chute 23 to complete the discharge after the solder paste is printed.

[0046] The working principle of the integrated circuit board mounting fixture proposed by the embodiment of the present invention is as follows:

[0047] The integrated circuit board body 9 and the steel mesh 10 can be placed horizontally by using a plurality of linkage blocks 85 on the top of the first horizontal plate 81. After placement, the integrated circuit board body 9 and the steel mesh 10 are synchronously and horizontally placed on the top of the supporting platform 22. The compression springs 88 at the bottom of the plurality of isolation plates 83 are used to enhance the shock resistance of the entire structure of the integrated circuit board body 9 in the installation fixture to prevent damage to the integrated circuit board body structure.

[0048] The output end of the second cylinder 5 pushes the positioning block 6 horizontally, causing the positioning block 6 to rise on both sides of the bottom of the integrated circuit board body 9. Finally, the two ends of the integrated circuit board body 9 and the steel mesh 10 are movably engaged with the inner wall of the limiting groove 12, so that the integrated circuit board body 9, the steel mesh 10 and the positioning groove 4 are arranged at the same level. Then, the output end of the first cylinder 1 pushes the positioning plate 3, causing the positioning groove 4 to movably engage the other two ends of the integrated circuit board body 9 and the steel mesh 10, so as to align the positions of the stacked integrated circuit board body 9 and the steel mesh 10 during the solder paste printing stage.

[0049] After the integrated circuit board body 9 and the steel mesh 10 are installed without manual stacking, the edges of the four surfaces at the connection between the integrated circuit board body 9 and the steel mesh 10 are in a flush state, which facilitates the application of solder paste to the upper surface of the steel mesh 10. The excess solder paste at the opening of the steel mesh 10 is applied to the upper surface of the integrated circuit board body 9 according to the position, which is used for the installation of the solder paste and the integrated circuit board body 9 after the integrated circuit board body 9 and the steel mesh 10 are positioned;

[0050] The output end of the first cylinder 1 drives the positioning plate 3 to slowly separate the positioning groove 4 from the integrated circuit board body 9 and the stencil 10. Then, the output end of the servo motor 26 drives the screw rod 27 to rotate, so that the linkage plate 29 threadedly connected to the screw rod 27 drives the scraper 28 to move horizontally. When the scraper 28 passes through the positioning groove 4 and approaches the connection between the integrated circuit board body 9 and the stencil 10, the integrated circuit board body 9 and the stencil 10 after the solder paste is printed are finally separated from each other.

[0051] The scraper 28 is used to support the separated steel mesh 10, and the separated integrated circuit board body 9 will fall into the top of several groups of linkage blocks 85 to support and buffer the effect. The output end of the third cylinder 7 can also drive the isolation plate 83 to move horizontally, so that several groups of positioning guide rails 84, in the process of being stored in the guide chute 25, will again use the low end position of the self-lowering slope 86 to first contact the guide chute 25, and gradually squeeze the linkage block 85 downward through the guide chute 25, so that after all the groups of linkage blocks 85 are stored in the guide chute 25, the first cross plate 81, the second cross plate 82 and the isolation plate 83 are finally moved synchronously into the storage groove 24, so as to form the purpose of the integrated circuit board body 9 falling from the discharge chute 23 to complete the discharge after the solder paste is printed.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
