Description
Technical Field
[0001] The utility model relates to the technical field of circuit board production, in particular to an anti-tilting welding jig for a plug-in module board. Background Art
[0002] During the welding process of the PCBA board and the module board of an industrial robot in AI artificial intelligence, the PCBA board is used as the main board, and the plug-in module board is used as the secondary board for welding, and signal connection is carried out through horizontal pin needles. However, this connection method has some problems. For example, when the plug-in pin needles are directly inserted into the PCBA main board, phenomena such as left-right skew and floating height may occur. These problems will cause the module board to still not be able to maintain a straight horizontal line even after being supported by cushion strips for welding. This not only affects the accurate installation of the module board into the structure cavity, but also may cause potential risks of reduced quality due to poor contact or short circuit.
[0003] In addition, in response to this problem, the customer has put forward clear requirements, that is, the module board welded on the main board must be on the same horizontal line as the main board, and no skew or floating height is allowed. Therefore, it is necessary to propose an anti-tilting welding jig for a plug-in module board to improve the above-mentioned existing defects. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the existing technology, the utility model provides an anti-tilting welding jig for a plug-in module board, which solves the problems of skew, floating height, and inability to maintain a straight horizontal line between the template and the main board during welding.
[0005] The technical solution of the utility model is as follows:
[0006] An anti-tilting welding jig for a plug-in module board, comprising:
[0007] A carrier plate and a limiting strip provided on the upper end surface of the carrier plate. The carrier plate is used for placing a circuit main board, and a plurality of positioning posts are provided on the limiting strip;
[0008] A positioning jig provided above the limiting strip. A plurality of positioning holes adapted to the limiting strip are provided on the positioning jig. A limiting groove is further provided on the positioning jig, and the limiting groove is used for inserting a plug-in module board. The positioning posts are inserted into the positioning holes to limit the position of the plug-in module board inserted into the limiting groove.
[0009] In a possible implementation manner, it further includes a plurality of first magnetic blocks, and the first magnetic blocks are embedded in the upper end surface of the limiting strip, and the first magnetic blocks are used to provide magnetic connection.
[0010] In a possible implementation, it further includes a second magnetic block adapted to the first magnetic block. The second magnetic block is embedded in the lower end face of the positioning jig, and the first magnetic block is magnetically connected to the second magnetic block for detachably connecting the limiting strip to the positioning jig.
[0011] In a possible implementation, the limiting strip is provided with a fixing perforation, and the carrier plate is provided with fixing screw holes corresponding to the fixing perforations.
[0012] In a possible implementation, it further includes a fixing member. The fixing member passes through the fixing perforation and is threadedly installed in the fixing screw hole. The fixing member is used to improve the structural stability of the connection.
[0013] In a possible implementation, the upper end face of the carrier plate is recessed to form a carrier plate position for placing the main board.
[0014] In a possible implementation, support members are provided on the inner wall of the carrier plate position. The support members include movable arms and lifting screw posts. One end of the movable arm is rotationally connected to the inner wall of the carrier plate position, and the other end is threadedly connected to the lifting screw post. The lifting screw post is used to support circuit main boards of different heights.
[0015] According to the above solution of the present utility model, its beneficial effect lies in that an anti-tilting soldering jig for a plug-in module board includes a carrier plate and a limiting strip and a positioning jig sequentially arranged above the carrier plate. Among them, through the structural setting of the positioning posts and positioning holes, the relative positions of the limiting strip and the positioning jig can be limited. In addition, through the structural setting of the limiting groove, the horizontal position of the plug-in module board inserted in the limiting groove can be limited. Therefore, through the structural setting of the carrier plate, the limiting strip, the positioning jig, and the limiting groove, the present utility model can limit the vertical direction of the plug-in module board and also limit the horizontal direction of the circuit main board, so that the present utility model can avoid the problem that the lower end face of the plug-in module board is misaligned and cannot be in contact with the upper end face of the circuit main board, resulting in the problem of floating height. At the same time, it can also avoid the problem that when multiple plug-in module boards are arranged on the same side of the circuit main board, the multiple plug-in module boards are not on the same horizontal line.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation manner:
[0021] It should be noted that during the production process of AI artificial intelligence industrial robots, specifically during the production process of circuit boards, it is necessary to weld plug-in module boards on the circuit main board. Among them, during the process of welding the plug-in module board on the circuit main board, first place one side of the lower end surface of the plug-in module board on the upper end surface of the circuit main board, and the layout of the plug-in module board is set in the vertical direction, and one end of the plug-in module board is first welded at a specified position on the circuit main board. In this way, it is very easy for the other end of the plug-in module board to be misaligned under the drive of the first welded end, that is, the lower end surface of the other end does not abut against the upper end surface of the circuit main board, which results in a gap between one end of the plug-in module board and the circuit main board, that is, the floating height phenomenon. In addition, even if the floating height phenomenon does not occur, when multiple plug-in module boards are installed on the circuit main board on the same side at the same time, it is extremely difficult to ensure that multiple plug-in module boards can be on the same horizontal line, which results in the installation accuracy of the plug-in module board being unable to accurately install the circuit main board into the structural cavity. To improve the above problems, the present utility model proposes an anti-tilt welding fixture for plug-in module boards.
[0022] As Figure 1 and Figure 2 shown, an anti-tilt welding fixture for plug-in module boards includes a carrier for the carrier board 10 and a limiting strip 20 provided on the upper end surface of the carrier for the carrier board 10. The carrier for the carrier board 10 is used to place the circuit main board, and a plurality of positioning posts 21 are provided on the limiting strip 20; in addition, a positioning fixture 30 is provided above the limiting strip 20. A plurality of positioning holes 31 adapted to the limiting strip 20 are provided on the positioning fixture 30. A limiting groove 32 is also provided on the positioning fixture 30. The limiting groove 32 is used to insert the plug-in module board. The positioning posts 21 are inserted into the positioning holes 31 to limit the position of the plug-in module board inserted into the limiting groove 32.
[0023] In this embodiment, the upper end surface of the carrier 10 is used to horizontally place the circuit main board. The limiting strip 20 is located on one side of the circuit main board, and the lower end surface of the limiting strip 20 is in contact with the upper end surface of the carrier 10. Among them, one side of the limiting strip 20 is in contact with the side of the circuit board main board, so as to limit the placement position of the circuit main board through the limiting strip 20. In addition, the positioning fixture 30 is arranged on the upper end surface of the limiting strip 20, and the lower end surface of the positioning fixture 30 is in contact with the upper end surface of the limiting strip 20. Specifically, the limiting strip 20 is provided with positioning posts 21, and the positioning fixture 30 is provided with positioning holes 31. When the limiting strip 20 moves from top to bottom to the upper end surface of the limiting strip 20, combined with the structural settings of the positioning posts 21 and the positioning holes 31, the descending path of the positioning fixture 30 is limited, so that the limiting groove 32 can be placed in a preset position, and further the plug-in module board inserted in the limiting groove 32 can be installed at a specified position on the circuit main board according to a predetermined position. It should be noted that through the structural settings of the carrier 10, the limiting strip 20, the positioning fixture 30, and the limiting groove 32, the present utility model can limit the vertical direction of the plug-in module board and also limit the horizontal direction of the circuit main board, so that the present utility model can avoid the problem that the lower end surface of the plug-in module board is misaligned and cannot be in contact with the upper end surface of the circuit main board, resulting in the problem of floating height. At the same time, it can also avoid the problem that when multiple plug-in module boards are arranged on the same side of the circuit main board, the multiple plug-in module boards are not on the same horizontal line, thereby improving the installation accuracy of the plug-in module board installed on the circuit main board and enabling the circuit main board to more precisely match the structural cavity.
[0024] Further, referring to Figure 1 , it further includes a plurality of first magnetic blocks 22, and the first magnetic blocks 22 are embedded in the upper end surface of the limiting strip 20. The first magnetic blocks 22 are used to provide magnetic connection to improve the connection convenience between the limiting strip 20 and the positioning fixture 30.
[0025] Further, referring to Figure 1 and Figure 2 , it further includes a second magnetic block 33 adapted to the first magnetic block 22. The second magnetic block 33 is embedded in the lower end surface of the positioning fixture 30. The first magnetic block 22 is magnetically connected to the second magnetic block 33 for detachably connecting the limiting strip 20 and the positioning fixture 30.
[0026] In this embodiment, the lower end surface of the positioning jig 30 is in abutting contact with the upper end surface of the limiting strip 20. Specifically, the upper end surface of the limiting strip 20 is recessed in a shape for inlaying a clamping hole for the first magnetic block 22, and the first magnetic block 22 is inlaid and installed in the clamping hole, so that the first magnetic block 22 is fixedly connected to the limiting strip 20. Similarly, the lower end surface of the positioning jig 30 is also recessed to form a clamping hole adapted to the second magnetic block 33, so that the second magnetic block 33 is fixedly connected to the positioning jig 30. Further specifically, both the first magnetic block 22 and the second magnetic block 33 are magnets, and the first magnetic block 22 and the second magnetic block 33 are magnets that attract each other with opposite polarities. Among them, when the positioning jig 30 descends along the positioning column 21 to the limiting strip 20, through the structural arrangement of the first magnetic block 22 and the second magnetic block 33, the relative position between the limiting strip 20 and the positioning jig 30 during the welding process can be prevented from being easily displaced. At the same time, through the magnetic connection method, it can be ensured that the limiting strip 20 and the positioning jig 30 are detachably connected, which is convenient for more easily disassembling the positioning jig 30 after the plug-in module board is welded to the circuit main board, thereby improving the welding efficiency to a certain extent.
[0027] Further, referring to Figure 1 and Figure 2 , a fixing through hole (not shown in the figure) is provided on the limiting strip 20, and a fixing screw hole (not shown in the figure) corresponding to the fixing through hole (not shown in the figure) is provided on the carrier plate 10.
[0028] Further, referring to Figure 1 and Figure 2 , a fixing member 40 is further included. The fixing member 40 is disposed through the fixing through hole (not shown in the figure) and is threadedly installed in the fixing screw hole (not shown in the figure). The fixing member 40 is used to improve the structural stability of the connection, thereby improving the structural stability of the connection between the limiting strip 20 and the carrier plate 10.
[0029] In this embodiment, the fixing member 40 can be a fixing screw. Specifically, one end of the fixing member 40 passes through the fixing through hole (not shown in the figure) of the limiting strip 20 and is threadedly installed in the fixing screw hole (not shown in the figure) of the carrier plate 10, so as to improve the structural stability of the connection between the limiting strip 20 and the carrier plate 10 through the fixing member 40. Further specifically, a receiving step is provided at one end of the fixing through hole (not shown in the figure) away from the carrier plate 10. The receiving step is used to receive and place the other end of the fixing member 40, so as to prevent one end of the fixing member 40 from being higher than the upper end surface of the limiting strip 20.
[0030] Further, referring to Figure 1 and Figure 2 , the upper end surface of the carrier plate 10 is recessed to form a carrier plate position 11, and the carrier plate position 11 is used to place the main board.
[0031] For further reference, Figure 1 and Figure 2 A support member 12 is provided on the inner wall of the board carrier position 11, and the support member 12 includes a movable arm 121 and a lifting stud 122. One end of the movable arm 121 is connected to the inner wall shaft of the board carrier position 11, and the other end is threadedly connected to the lifting stud 122. The lifting stud 122 is used to support circuit motherboards of different heights.
[0032] In this embodiment, a carrier position 11 is provided on the upper end surface of the carrier 10, and the circuit board is placed on the carrier position 11, and the peripheral side of the circuit board is in contact with the inner wall of the carrier position 11, so that the circuit board is fixed in the horizontal direction by the carrier position 11. In addition, a support member 12 is provided in the carrier position 11, and the support member 12 is used to support the circuit board. Specifically, the lifting stud 122 is used to support the lower end surface of the circuit board, and is designed by connecting one end of the movable arm 121 with the inner wall of the carrier position 11 by a rotating shaft. Thus, by rotating the movable arm 121, the lifting stud 122 can be driven to move in the horizontal direction, wherein a lifting threaded hole is provided at the other end of the movable arm 121, and the lifting stud 122 can be lifted and lowered in the vertical direction in the lifting threaded hole. By lifting and adjusting the lifting stud 122, the vertical height of the circuit board in the carrier position 11 is changed, so that the utility model can match circuit boards of different thicknesses. At the same time, by changing the vertical height of the circuit board, it is easier to adjust the height position of the plug-in module board, so that the abutting surfaces of the two are more suitable for welding.
[0033] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
[0034] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
