DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 3As shown, a locking auxiliary device provided in this embodiment includes a first positioning unit 1, a platform 2, and a second positioning unit 3 arranged in sequence along a first direction A in a horizontal plane, wherein the platform 2 is used for pre-positioning the columnar member 300 to be connected, and the first positioning unit 1 and the second positioning unit 3 both include: a first drive assembly 4, a second drive assembly 5, and a clamping and fixing assembly 6, wherein the second drive assembly 5 is arranged at the power output end of the first drive assembly 4, and can be switched between the first position and the second position under the action of the first drive assembly 4. The clamping and fixing assembly 6 is arranged at the power output end of the second drive assembly 5, and when the second drive assembly 5 is in the first position, the clamping and fixing assembly 6 can be switched between the first clamping position and the first waiting position under the action of the second drive assembly 5. When the second drive assembly 5 is in the second position, the clamping and fixing assembly 6 can be switched between the second clamping position and the second waiting position under the action of the second drive assembly 5. When the clamping and fixing assembly 6 is in the first clamping position and the second clamping position, the clamping and fixing assembly 6 can clamp and fix a columnar member 300 to be connected pre-positioned on the platform 2. The locking auxiliary device provided in this embodiment can be used to connect the other ends of the four hexagonal copper pillars 200 connected to the printed circuit board to another printed circuit board through screw locking. In other words, the hexagonal copper pillars 200 connected to the printed circuit board can be used as the above-mentioned columnar member 300 to be connected to solve the problem that the relative position between the printed circuit board to be connected and the hexagonal copper pillars 200 cannot be effectively fixed, and the screws will drive the hexagonal copper pillars 200 to rotate during the locking operation, so that the screws are not locked tightly and the screws are slipped, which seriously affects the production operation efficiency. It is not difficult to understand that when the hexagonal copper pillars 200 connected to the printed circuit board are used as the above-mentioned columnar member 300 to be connected, the printed circuit board 101 previously connected to the hexagonal copper pillars 200 is the first circuit board 400 mentioned in this embodiment, and the printed circuit board 102 connected to the other end of the hexagonal copper pillars 200 is the second circuit board 500 mentioned in this embodiment.

[0025] Specifically, when the other ends of the four hexagonal copper pillars 200 connected to the printed circuit board are connected to another printed circuit board by screw locking using the locking auxiliary device provided in this embodiment, the steps may be as follows:

[0026] Step 1: Position the printed circuit board to which the four hexagonal copper pillars 200 are connected on the carrier 2, so as to pre-position each hexagonal copper pillar 200; it is not difficult to understand that the four hexagonal copper pillars 200 are located above the above-mentioned printed circuit board so that the other ends of the four hexagonal copper pillars 200 can be connected to another printed circuit board.

[0027] Step 2: The clamping and fixing assembly 6 in the first positioning unit 1 is driven to the first clamping position by the first driving assembly 4 and the second driving assembly 5 in the first positioning unit 1, so that the clamping and fixing assembly 6 in the first positioning unit 1 can clamp and fix a hexagonal copper column 200.

[0028] The clamping and fixing assembly 6 in the second positioning unit 3 is driven to the first clamping position by the first driving assembly 4 and the second driving assembly 5 in the second positioning unit 3 , so that the clamping and fixing assembly 6 in the second positioning unit 3 can clamp and fix another hexagonal copper column 200 .

[0029] Step 3: Place the circuit boards to be connected on top of the hexagonal copper pillars 200, and then screw the hexagonal copper pillars 200 fixed by the clamping and fixing components 6 together with the circuit boards to be connected;

[0030] Step 4: Drive the clamping and fixing component 6 in the first positioning unit 1 to the second clamping position through the first driving component 4 and the second driving component 5 in the first positioning unit 1, so that the clamping and fixing component 6 in the first positioning unit 1 can clamp and fix a hexagonal copper column 200 that is not connected to the circuit board to be connected.

[0031] The clamping and fixing component 6 in the second positioning unit 3 is driven to the second clamping position by the first driving component 4 and the second driving component 5 in the second positioning unit 3, so that the clamping and fixing component 6 in the second positioning unit 3 can clamp and fix another hexagonal copper column 200 that is not connected to the circuit board to be connected.

[0032] Step 5: Use screws to lock the hexagonal copper column 200 fixed by the clamping and fixing component 6 and the circuit board to be connected together.

[0033] It should be understood that the locking auxiliary device provided in this embodiment is also applicable to the clamping and fixing of the columnar member 300 to be connected in other scenarios, for example, in the scenario where both ends of the columnar member 300 to be connected are not connected to the circuit board in advance, and one end of the columnar member 300 to be connected needs to be connected to the circuit board by screw locking. The columnar member 300 to be connected is not limited to being a hexagonal copper column 200, but may also be other columnar members, such as a pentagonal column, etc. The number of the columnar members 300 to be connected is not limited to 4, but may also be 3, 5, 6 or more.

[0034] When the locking auxiliary device provided in this embodiment is used to connect the other end of the hexagonal copper column 200 connected to the printed circuit board to another printed circuit board by screw locking, such as Figure 4As shown, in an optional implementation, a limiting groove 21 is formed on the top surface of the carrier 2, and the limiting groove 21 is used to position the first circuit board 400 (that is, the printed circuit board pre-connected with the hexagonal copper column 200) connected to the columnar member 300 to be connected, so as to achieve pre-positioning of the columnar member 300 to be connected.

[0035] Furthermore, a clearance hole 211 is formed on the bottom wall of the limiting groove 21 , and the clearance hole 211 is used to avoid the fasteners connecting the columnar member 300 to be connected and the first circuit board 400 , so as to make the pre-positioning of the columnar member 300 to be connected more reliable.

[0036] It should be understood that the limiting groove 21, the avoidance hole 211 and the positioning groove 221 mentioned below are positioned according to the shape of the corresponding product. For example, if the shape of the first circuit board 400 is a rectangle, the limiting groove 21 is a rectangle matching the shape of the first circuit board 400. If the shape of the second circuit board 500 is a rectangle, the positioning groove 221 can limit the corresponding end of the second circuit board 500.

[0037] Still taking the case where the locking auxiliary device provided in this embodiment is used to connect the other end of the hexagonal copper column 200 connected to the printed circuit board to another printed circuit board by screw locking as an example, please continue to refer to Figure 4 In an optional implementation, a positioning portion 22 is provided on the top surface of the carrier 2, and the positioning portion 22 is located at one end of the carrier 2 in the second direction B, and has a positioning groove 221 for positioning one end of the second circuit board 500, so as to provide support and positioning for the second circuit board 500 (that is, the printed circuit board to be connected to the other end of the hexagonal copper column 200).

[0039] Furthermore, in a possible implementation, the first drive assembly 4 includes a first limit adjustment assembly 42, which is used to adjust the extreme position of the extension of the piston rod of the first cylinder 41, so that the first clamping position and the second clamping position of the clamping and fixing assembly 6 can be more accurate, and the clamping and fixing assembly 6 can reliably clamp and fix the columnar member 300 to be connected.

[0040] Exemplarily, the first limit adjustment assembly 42 includes a first bolt 421 and a first limit block 422. A first connection block 423 is fixedly provided on the outside of the cylinder body of the first cylinder 41. The first bolt 421 is threadedly connected to the first connection block 423, and the axial direction of the first bolt 421 is parallel to the extension direction of the piston rod of the first cylinder 41. The first limit block 422 is located outside the cylinder body of the first cylinder 41 and is fixedly connected to the piston rod of the first cylinder 41. The first bolt 421 and the first limit block 422 can cooperate to limit the maximum stroke of the piston rod of the first cylinder 41.

[0041] In a possible implementation, the second driving assembly 5 includes a second cylinder 51 , and a piston rod of the second cylinder 51 can reciprocate along the first direction A.

[0042] Furthermore, in a possible implementation, the second drive assembly 5 includes a second limit adjustment assembly 52, which is used to adjust the extreme position of the extension of the piston rod of the second cylinder 51, so that the first clamping position and the second clamping position of the clamping and fixing assembly 6 can be more accurate, and the clamping and fixing assembly 6 can reliably clamp and fix the columnar member 300 to be connected.

[0043] Exemplarily, the second limit adjustment assembly 52 includes a second bolt 521 and a second limit block 522. A second connection block 523 is fixedly provided on the outside of the cylinder body of the second cylinder 51. The second bolt 521 is threadedly connected to the second connection block 523, and the axial direction of the second bolt 521 is parallel to the extension direction of the piston rod of the second cylinder 51. The second limit block 522 is located outside the cylinder body of the second cylinder 51 and is fixedly connected to the piston rod of the second cylinder 51. The second bolt 521 and the second limit block 522 can cooperate to limit the maximum stroke of the piston rod of the second cylinder 51.

[0044] When the clamping and fixing assembly 6 is specifically provided, in a possible implementation, the clamping and fixing assembly 6 includes a pneumatic clamping jaw, which is more convenient and reliable for clamping and fixing the hexagonal copper column 200 to be connected.

[0045] The locking auxiliary device may further include a control switch 600 , which is electrically connected to the first drive assembly 4 , the second drive assembly 5 and the clamping and fixing assembly 6 , and is used to control the actions of the first drive assembly 4 , the second drive assembly 5 and the clamping and fixing assembly 6 .

[0047] The following is an example of the operation steps of using the locking auxiliary device provided in this embodiment to connect the other ends of the four hexagonal copper pillars 200 connected to the printed circuit board to another printed circuit board by screw locking:

[0050] Step 3: Position the printed circuit board to be connected on the carrier 2;

[0051] Step 4: Use an electric screwdriver to lock the two hexagonal copper columns 200 fixed by the pneumatic clamp with fixing screws;

[0052] Step 5: After the locking is completed, the pneumatic clamp is switched to the first waiting position under the action of the second driving assembly 5;

[0053] Step 6. Press the start switch again;
