Description

One end of the first positioning rod 121 is installed in the first mounting hole, and the other end is installed in the second mounting hole 1231. The first positioning rod 121 can slide relative to the first mounting seat 122 and the second mounting seat 123 along the length direction of the positioning seat 100.

[0050] Both the first mounting seat 122 and the second mounting seat 123 are installed on the lower side of the positioning seat 100. In the length direction of the positioning seat 100, a plurality of positioning grooves 101 are located between the first mounting seat 122 and the second mounting seat 123.

[0051] A plurality of the circuit board position adjusting units 124 are all installed on the first positioning rod; the plurality of circuit board position adjusting units 124 correspond to the plurality of positioning grooves 101 one by one. Each circuit board position adjusting unit 124 passes through the corresponding positioning hole 102 and extends into the corresponding positioning groove 101.

[0052] Exemplarily, Figure 1 Among them, a corresponding circuit board position adjusting unit 124 is provided in each positioning hole 102.

The upper end of the circuit board position adjusting unit 124 passes through the corresponding positioning hole 102 into the corresponding positioning groove 101, and the lower end is fixedly connected to the first positioning rod 121.

[0053] In summary, for the circuit board positioning device 10 provided in the embodiments of the present application, a plurality of positioning slots 101 are provided on the upper side of the positioning base 100, and a circuit board position adjusting unit 124 is provided for each positioning slot 101. A first positioning rod 121, a first mounting base 122, and a second mounting base 123 are provided on the lower side of the positioning base 100, so that the first positioning rod 121 can slide along the length direction of the positioning base 100, and thus can drive each circuit board position adjusting unit 124 to move in its corresponding positioning hole 102, realizing the function of positioning the circuit board in the corresponding positioning slot 101. That is, through the movement of the plurality of circuit board position adjusting units 124 in the length direction of the positioning base 100, the circuit board positioning device 10 can simultaneously abut a plurality of circuit boards to be positioned against the inner side walls of the corresponding positioning slots 101, realizing the fixing operation of the plurality of circuit boards, thereby solving the problem of difficult positioning of a plurality of circuit boards described in the background art.

[0054] In some embodiments, both the first mounting base 122 and the second mounting base 123 are in a plate-like structure.

[0055] In some embodiments, the first positioning rod 121 is cylindrical. Further, the first positioning rod 121 can be set as a positioning shaft.

[0056] In some embodiments, the shape of the positioning hole 102 is generally rectangular, and its length direction is the same as the length direction of the positioning base 100.

[0057] In some embodiments, the circuit board position adjusting unit 124 includes a positioning slider 1241 and a positioning strip 1242; the positioning strip 1242 is installed on the corresponding positioning slider 1241, the positioning slider 1241 is installed on the first positioning rod 121, the positioning slider 1241 is located below the corresponding positioning slot 101 and is fixedly connected to the lower end of the positioning strip 1242; the positioning strip 1242 passes through the corresponding positioning hole 102 into the corresponding positioning slot 101. For example Figure 1 As shown, the upper end of the positioning strip 1242 extends out of the corresponding positioning hole 102 into the positioning slot 101. Thus, when the first positioning rod 121 slides along the length direction of the positioning base 100, the positioning strip 1242 can be driven to move in the positioning hole 102 through the positioning slider 1241.

[0058] In some embodiments, a connection groove 12414 is provided on the positioning slider 1241, and the lower end of the positioning strip 1242 is installed in the connection groove 12414.

[0059] In some embodiments, the thickness of the positioning slider 1241 is greater than the thickness of the positioning strip 1242, and the width of the positioning slider 1241 is greater than the width of the positioning strip 1242.Figure 1 In the example of Figure 1 , the thickness refers to the dimension in the front - to - back direction, and the width refers to the dimension in the left - to - right direction.

[0060] In some embodiments, the positioning slider 1241 is sleeved on the outer periphery of the first positioning rod 121. Specifically, the positioning slider 1241 is provided with a first connection hole 12411 corresponding to the first positioning rod 121, and the first positioning rod 121 passes through the first connection hole 12411. It is easy to understand that in certain embodiments, the outer peripheral wall of the first positioning rod 121 abuts against the inner side wall of the first connection hole 12411.

[0061] In some embodiments, the positioning assembly 120 further includes a second positioning rod 125 and a third positioning rod 126, and the positioning strip is located between the second positioning rod 125 and the third positioning rod 126. For example Figure 2 As shown, the second positioning rod 125 is located on the left side of the positioning strip 1242, and the third positioning rod 126 is located on the right side of the positioning strip 1242; one end of the second positioning rod 125 is fixedly connected to the first mounting seat 122, and the other end is fixedly connected to the second mounting seat 123; one end of the third positioning rod 126 is fixedly connected to the first mounting seat 122, and the other end is fixedly connected to the second mounting seat 123. The second positioning rod 125 is located on one side of the first positioning rod 121, and the third positioning rod 126 is located on the other side of the first positioning rod 121. It can improve the structural stability of the circuit board positioning device 10 and prevent the first positioning rod 121 from shaking during operation.

[0062] In some embodiments, both the second positioning rod 125 and the third positioning rod 126 are cylindrical. Further, both the second positioning rod 125 and the third positioning rod 126 can be set as positioning shafts.

[0063] In some embodiments, the positioning slider 1241 is further provided with a second connection hole 12412 corresponding to the second positioning rod 125 and a third connection hole 12413 corresponding to the third positioning rod 126. The second positioning rod 125 passes through the second connection hole 12412, and the third positioning rod 126 passes through the third connection hole 12413. The positioning slider 1241 can slide relative to the second positioning rod 125 and the third positioning rod 126. In this embodiment, the sliding stability of the positioning slider 1241 can be improved.

[0064] In some embodiments, the circuit board position adjusting unit 124 further includes a first sliding bearing 1244 corresponding to the second positioning rod 125 and a second sliding bearing 1245 corresponding to the third positioning rod 126. The first sliding bearing 1244 is sleeved on the outer periphery of the second positioning rod 125, and the second sliding bearing 1245 is sleeved on the outer periphery of the third positioning rod 126. The first sliding bearing 1244 is sleeved inside the second connection hole 12412, and the second sliding bearing 1245 is sleeved inside the third connection hole 12413.

[0065] As an example, the first sliding bearing 1244 is a graphite bearing, and the second sliding bearing 1245 is also a graphite bearing.

[0066] In some embodiments, the positioning assembly 120 further includes a driving cylinder 127. The driving cylinder 127 is installed on the first mounting seat 122. The piston rod of the driving cylinder 127 extends into the first mounting hole and is fixedly connected to one end of the first positioning rod 121. When the piston rod of the driving cylinder 127 makes a telescopic movement along the length direction of the positioning seat 100, the first positioning rod 121 can be driven to slide.

[0067] In some embodiments, the positioning assembly 120 further includes a third sliding bearing 129. The third sliding bearing 129 is sleeved inside the second mounting hole 1231 and is sleeved on the outer periphery of the other end of the first positioning rod 121. The sliding performance of the first positioning rod 121 relative to the second mounting seat 123 is improved. As an example, the third sliding bearing 129 is a graphite bearing.

[0068] Regarding how the first positioning rod 121 drives the positioning slider 1241 to move, there are various different implementation manners. In some embodiments, the positioning slider 1241 can be fixedly installed on the first positioning rod 121, that is to say, the positioning slider 1241 is stationary relative to the first positioning rod 121. In addition, it can also be implemented in the following manner.

[0069] As an example where the positioning slider 1241 is not fixedly connected to the first positioning member. The circuit board position adjusting unit 124 further includes a first fixing ring 1243. The first fixing ring 1243 is fixedly sleeved on the outer periphery of the first positioning rod 121, and the first fixing ring 1243 abuts against the side wall on one side of the positioning slider 1241.

[0070] The positioning assembly 120 further includes a plurality of buffer members 130. Each positioning slider 1241 corresponds to a buffer member 130. The plurality of buffer members 130 are sequentially sleeved on the outer periphery of the first positioning rod 121, and one end of the buffer member 130 is connected to the other side of the corresponding positioning slider 1241.

[0071] A second fixing ring 131 is further provided between every two adjacent positioning sliders 1241, and the second fixing ring 131 is fixedly sleeved on the outer periphery of the first positioning rod 121;

[0072] The other end of the first positioning rod 121 extends radially (i.e., the direction perpendicular to the length direction) around to form a convex portion 1211;

[0073] Among the plurality of buffer members 130, for the buffer member 130 close to the first mounting seat 122, the other end thereof abuts against the convex portion 1211; the other ends of the other buffer members 130 abut against the nearby second fixing ring 131.

[0074] It should be noted that the buffer member 130 can be set as a spring. More specifically, it can be a cylindrical compression spring.

[0075] In this embodiment, the positioning slider 1241 is not fixedly connected to the first positioning member, and its position is defined by mechanisms such as the buffer member 130, the first fixing ring 1243, the second fixing ring 131, and the convex portion of the first positioning rod 121. Therefore, during the process of adjusting the position of the circuit board, a better buffering effect can be achieved, reducing the risk of damage to the circuit board. Specifically, when the position of the circuit board needs to be adjusted, the first positioning rod 121 can be driven to move forward from the back, driving the positioning slider 1241 and the positioning strip 1242 to move closer to the circuit board. When the positioning strip 1242 touches the circuit board and is subjected to resistance, the buffer member 130 will be compressed, relieving the action generated by the resistance and avoiding collision hazards to the circuit board. After the positioning operation of the circuit board is completed, when the buffer member 130 is not subjected to external force, it can recover its deformation, and the positioning slider 1241 is abutted against the corresponding first fixing ring 1243 to define its position, facilitating the implementation of the next operation.

[0076] In some embodiments, the positioning assembly 120 further includes a fixing block 132 and a fourth sliding bearing 133; the upper end of the fixing block 132 is fixedly installed on the lower side or the bottom side of the positioning seat 100; a fixing hole (not shown in the figure) is provided on the fixing block 132, the fourth sliding bearing 133 is sleeved inside the fixing hole and is sleeved on the outer periphery of the first positioning rod 121, and the first positioning rod 121 can slide relative to the fixing block 132 or the fourth sliding bearing 133. Further improving the structural stability of the circuit board positioning device 10 and preventing the first positioning rod 121 from shaking.

[0077] As an example, the fourth sliding bearing 133 is a graphite bearing.

[0078] In some embodiments, the circuit board positioning device 10 further includes a first support base 140 and a second support base 160. The first support base 140 is fixedly installed on one side of the bottom of the positioning base 100, and the second support base 160 is fixedly installed on the other side of the bottom of the positioning base 100.
