DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Figure 1 A schematic diagram of a circuit board and stud locking device provided in an embodiment of the present application. Figure 2 for Figure 1 The exploded view of the locking device of the circuit board and the stud shown is worth explaining. Figure 2 Also shown are some copper pillars 100 to be connected. Figure 2 The drive structure is not shown. Figure 1 and Figure 2As shown, the locking device for the circuit board and the stud comprises a mounting seat 4, a first component 1, a second component 2, a third component 3 and a driving structure, wherein the mounting seat 4 has a receiving cavity 401 with an open top. The first component 1, the second component 2 and the third component 3 are arranged in sequence along the first direction A in the receiving cavity 401, and the first component 1 and the third component 3 are slidably connected to the receiving cavity 401 along the first direction A. A first limiting portion 11 is provided on the side of the first component 1 facing the second component 2, a second limiting portion 31 is provided on the side of the third component 3 facing the second component 2, a third limiting portion 21 opposite to the first limiting portion 11 is provided on the side of the second component 2 facing the first component 1, and a fourth limiting portion 22 opposite to the second limiting portion 31 is provided on the side of the second component 2 facing the third component 3. The first component 1 and the third component 3 are both connected to the driving structure in a transmission manner. When the first component 1 and the third component 3 are in the first working position under the action of the driving structure, the first limiting portion 11 and the third limiting portion 21 jointly enclose a first limiting hole a, and the second limiting portion 31 and the fourth limiting portion 22 jointly enclose a second limiting hole b. The shapes of the first limiting hole a and the second limiting hole b can match the shape of the copper column 100 to be connected. The locking device of the circuit board and the stud provided in this solution can fix the copper column 100 to be connected through the first limiting hole a and the second limiting hole b whose shapes match the shape of the copper column 100 to be connected, thereby avoiding the situation that the screw drives the hexagonal copper column to rotate during the locking operation, thereby avoiding the occurrence of the situation that the screw is not locked tightly and the screw is slipping, which is conducive to improving the production operation efficiency.

[0027] It should be understood that the shapes of the first limiting portion 11, the second limiting portion 31, the third limiting portion 21 and the fourth limiting portion 22 are designed according to the outer shape of the copper column 100 to be connected, so that when the first component 1 and the third component 3 are in the first working position under the action of the driving structure, the hole walls of the first limiting hole a and the second limiting hole b can at least partially fit with the outer wall of the copper column 100 to be connected and fix the copper column 100 to be connected. Exemplarily, the cross-sectional shape of the first limiting hole a and the second limiting hole b can be the same as the cross-sectional shape of the copper column 100 to be connected. For example, the cross-sectional shape of the copper column 100 to be connected is a regular hexagon, and the cross-sectional shapes of the first limiting hole a and the second limiting hole b are also regular hexagons. In this case, there are many possibilities for the specific shape of each limiting portion. Taking the first limiting hole a as an example, the first limiting portion 11 and the third limiting portion 21 are symmetrical structures, and the two cooperate to enclose the first limiting hole a with a regular hexagonal cross-sectional shape, such as Figure 1As shown. Of course, the cross-sectional shape of the first limiting hole a and the second limiting hole b may also be different from the cross-sectional shape of the copper column 100 to be connected. In this case, there are also many possibilities for the specific shape of each limiting portion. Taking the first limiting hole a as an example, the first limiting portion 11 and the third limiting portion 21 are symmetrical structures, both of which are V-shaped grooves. When the first component 1 is in the first working position, the first limiting portion 11 and the third limiting portion 21 are respectively fitted with two adjacent wall surfaces of the copper column 100 to be connected, thereby being clamped with the copper column 100 to be connected.

[0028] It is worth noting that the first limiting hole a can be interrupted by the gap between the first component 1 and the second component 2 at the junction of the first component 1 and the second component 2, that is, the first component 1 is in the first position under the action of the driving structure, and there can be a gap between the first component 1 and the second component 2. Of course, the first limiting portion 11 and the third limiting portion 21 are not limited to symmetrical structures, but can also be asymmetrical structures, as long as the two can cooperate to position the copper column 100 to be connected, that is to say, this is not exhaustive. In addition, the shape of the second limiting hole b can be the same as the shape of the first limiting hole a, or it can be different from the shape of the first limiting hole a.

[0029] Further, the number of the first limiting portion 11 and the second limiting portion 31 can be one, two or more, each first limiting portion 11 is opposite to a third limiting portion 21, each first limiting portion 11 and the third limiting portion 21 opposite thereto jointly enclose a first limiting hole a; each second limiting portion 31 is opposite to a fourth limiting portion 22, each second limiting portion 31 and the fourth limiting portion 22 opposite thereto jointly enclose a second limiting hole b. It is not difficult to understand that the number and arrangement of the first limiting portion 11 and the second limiting portion 31 can be set according to actual needs.

[0030] In some specific implementations, the second component 2 is fixedly connected to the mounting seat 4, that is, the first component 1 and the third component 3 can both move toward the second component 2 under the action of the driving structure, and the positioning of the copper column 100 to be connected is based on the second component 2. Compared with the case where the second component 2 is also slidably connected to the mounting seat 4, the positioning of the copper column 100 to be connected is more accurate.

[0031] For example, please combine Figure 1-Figure 4The mounting seat 4 includes a base plate 41, a limiting plate 42 and two cover plates 43, wherein the limiting plate 42 is fixed to the top surface of the base plate 41, and the driving structure is also fixed to the base plate 41. The limiting plate 42 has a rectangular parallelepiped groove, which forms the above-mentioned accommodating cavity 401. The two cover plates 43 are respectively fixed to one of a set of opposite sides of the limiting plate 42, and extend moderately into the accommodating cavity 401, thereby defining a slide groove structure together with the limiting plate 42, so that the first component 1 and the third component 3 can be slidably arranged on the mounting seat 4. It is not difficult to understand that the cover plate 43 and the limiting plate 42 are detachably fixedly connected, for example, bolted.

[0032] In a specific embodiment, the driving structure includes a first driving assembly 51 and a second driving assembly 52, wherein the power output end of the first driving assembly 51 is transmission-connected with the first component 1, and can drive the first component 1 to move to the above-mentioned first station. The power output end of the second driving assembly 52 is transmission-connected with the third component 3, and can drive the third component 3 to move to the above-mentioned first station.

[0033] Of course, in other embodiments, the first component 1 and the third component 3 may also share a driving structure, and the driving structure synchronously drives the first component 1 and the third component 3 through a transmission assembly, and the specific structure will not be described in detail here.

[0034] For example, please combine Figure 3 and Figure 5 , the first driving assembly 51 includes a first cylinder, and the second driving assembly 52 includes a second cylinder; the mounting seat 4 includes a first through hole opposite to the first component 1 and a second through hole opposite to the third component 3, and the axes of the first through hole and the second through hole are parallel to the first direction A; the power output end of the first cylinder (that is, the piston rod of the first cylinder) is inserted in the first through hole to act on the first component 1; the power output end of the second cylinder (that is, the piston rod of the second cylinder) is inserted in the second through hole to act on the third component 3. In specific implementation, the first cylinder and the second cylinder can both be micro cylinders to reduce the volume of the locking device of the circuit board and the stud.

[0035] Furthermore, please combine Figure 5 and Figure 6The locking device of the circuit board and the stud comprises a first elastic reset component 6 and a second elastic reset component 7, wherein the first elastic reset component 6 is located between the first component 1 and the second component 2 and can separate the first component 1 from the second component 2, and the second elastic reset component 7 is located between the second component 2 and the third component 3 and can separate the second component 2 from the third component 3. In this way, when the circuit board 200 (for example, PCB) to be connected is connected with the copper column 100 to be connected, the first component 1 and the third component 3 can move in the direction opposite to the second component 2 under the action of the corresponding first elastic reset component 6 and the second elastic reset component 7, thereby releasing the fixation of the copper column 100 to be connected, so as to facilitate the removal of the copper column and the circuit board after connection. In addition, the movement of the first component 1 and the third component 3 in the direction opposite to the second component 2 does not rely on the driving structure, so that the first component 1 and the third component 3 do not need to be connected to the driving structure, which can simplify the structure and assembly of the locking device of the circuit board and the stud, and is conducive to improving the assembly efficiency of the locking device of the circuit board and the stud.

[0036] In specific implementation, in some embodiments, the number of the first elastic reset component 6 and the second elastic reset component 7 can be one, two or more, which can be set according to actual needs. The first elastic reset component 6 and the second elastic reset component 7 can both include springs, and when the first component 1 and the third component 3 are in the first position under the action of the driving structure, the first elastic reset component 6 and the second elastic reset component 7 are both in a compressed state.

[0037] For example, please refer to Figure 5 and Figure 6 , the first component 1 is provided with a first blind hole 12 corresponding to the corresponding spring at one end facing the second component 2, and the third component 3 is provided with a second blind hole corresponding to the corresponding spring at one end facing the second component 2, and the axial directions of the first blind hole 12 and the second blind hole are parallel to the first direction A. The second component 2 is provided with a third blind hole opposite to the first blind hole 12 and a fourth blind hole 23 opposite to the second blind hole 32, and the corresponding springs are respectively located between the corresponding first blind hole 12 and the third blind hole, and between the second blind hole and the fourth blind hole 23. It is not difficult to understand that the first blind hole 12 and the third blind hole are in one-to-one correspondence with the first elastic reset component 6, and the second blind hole and the fourth blind hole 23 are in one-to-one correspondence with the second elastic reset component 7. The direction perpendicular to the first direction A and parallel to the bottom surface of the accommodating cavity 401 is the second direction B. In some embodiments, the first elastic reset component 6 and the second elastic reset component 7 each include two springs spaced apart along the second direction B.

[0038] like Figure 7As shown, in some embodiments, the top of the first component 1 is provided with a first positioning portion 13, the top of the second component 2 is provided with a second positioning portion 25 and a third positioning portion 26 spaced apart in the second direction B, and the top of the third component 3 is provided with a fourth positioning portion 33. The first positioning portion 13, the second positioning portion 25, the third positioning portion 26 and the fourth positioning portion 33 are used to work together to position the circuit board 200 to be connected. In other words, the locking device of the circuit board and the stud provided in this embodiment can simultaneously position the circuit board 200 to be connected and the copper column 100 to be connected, which is conducive to making the relative position of the circuit board 200 to be connected and the copper column 100 to be connected more accurate. Exemplarily, when the locking device of the circuit board and the stud provided in this embodiment is used, the circuit board is located above the hexagonal copper column.

[0039] like Figure 8 As shown, in a specific implementation, the locking device of the circuit board and the stud includes a control switch 8, which is electrically connected to the driving structure and is used to control the action of the driving structure, so that the first component 1 and the third component 3 move toward the direction close to the second component 2 under the action of the driving structure.

[0040] The operation flow when using the locking device for a circuit board and a stud provided in this embodiment can be as follows:

[0041] Step 1: Reset the first component 1 and the third component 3; after confirming that the first component 1 and the third component 3 are both at positions away from the second component 2, put the hexagonal copper column into the first limiting hole a and the second limiting hole b respectively.

[0042] Step 2: Press the control switch 8, and the first component 1 and the third component 3 are moved to the first position under the action of the driving structure, and cooperate with the second component 2 to clamp the hexagonal copper column;

[0043] Step 3: Place the camera PCB on the first positioning portion 13, the second positioning portion 25, the third positioning portion 26 and the fourth positioning portion 33;

[0044] Step 4. Use an electric screwdriver to tighten the screws and fix the hexagonal copper column to the PCB.

[0045] Step 5: Press the control switch 8 again, and the driving structure drives the first component 1 and the third component 3 to reset and release the hexagonal copper column.

[0046] Step 6: Take out the completed product.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
