[0036] Please refer to Figure 1 and Figure 2 The present embodiment discloses a PCB (printed circuit board) clamping jaw for clamping a PCB, the PCB comprising a PCB substrate 910 and a plurality of electronic components mounted on the PCB substrate 910, comprising a clamping jaw substrate 100, a first linear module 200, a first clamping jaw assembly 300 and a second clamping jaw assembly 400; the first linear module 200 extends along a first direction (X direction shown in the figure); the first clamping jaw assembly 300 and the second clamping jaw assembly 400 are connected to the clamping jaw substrate 100 through the first linear module 200, and are adapted to relatively move along the first direction under the driving of the first linear module 200 to clamp the PCB; at least one of the first clamping jaw assembly 300 and the second clamping jaw assembly 400 is provided with a flexible abutting portion 310, and the flexible abutting portion 310 is adapted to abut with the PCB substrate 910.

[0037] It should be noted that in the related art, the PCB clamping jaw is connected with the PCB board through a hard connection, so as to avoid damage to the electronic elements on the PCB substrate 910, and the PCB clamping jaw can only clamp the PCB substrate 910, thereby limiting the distribution of the electronic elements on the PCB substrate 910 during the design and production of the PCB board, and the PCB clamping jaw cannot be adapted to the existing PCB board that has been designed, such as the PCB board in which some electronic elements are located at the edge of the PCB substrate 910.

[0038] According to the PCB clamping jaw provided in the embodiment of the present application, when the PCB board is clamped, the flexible abutting portion 310 on the first clamping jaw assembly 300 or the second clamping jaw assembly 400 is in contact with the edge of the PCB substrate 910 and deforms to clamp and fix the whole PCB board. When the corresponding flexible abutting portion 310 on the PCB board is in contact with the position of the electronic element on the PCB board, the flexible abutting portion 310 will change according to the shape of the electronic element and will not cause damage to the electronic element. The PCB clamping jaw can clamp the PCB board in which the electronic element is arranged at the edge of the PCB substrate 910, thereby improving the clamping adaptability of the PCB clamping jaw to the existing PCB board and further widening the design diversity of the future PCB structure.

[0039] In the embodiment, the flexible abutting portion 310 can be made of anti-static silica gel, which can improve the friction between the PCB clamping jaw and the PCB board and prevent static electricity from damaging the electronic element.

[0040] In the embodiment, the first linear module 200 is in the form of a sliding table module, and two sliding tables are arranged on the guide rail of the first linear module 200, and the two sliding tables are respectively connected with the first clamping jaw assembly 300 and the second clamping jaw assembly 400. Of course, other embodiments can also use positive and negative screw rod modules, double-head air cylinders, etc.

[0041] In the embodiment, the PCB clamping jaw is provided with two first linear modules 200, which can improve the stability of the relative movement of the first clamping jaw assembly 300 and the second clamping jaw assembly 400. Of course, the specific number can be adjusted based on actual needs.

[0042] In some embodiments, as shown in Figure 1 and Figure 2 One of the first clamping jaw assembly 300 and the second clamping jaw assembly 400 is provided with a flexible abutting portion 310, and the other is provided with a positioning groove 411. The slot of the positioning groove 411 is arranged opposite to the flexible abutting portion 310 along the first direction, and the positioning groove 411 is suitable for clamping the PCB substrate 910. During installation, the flexible abutting portion 310 of the first clamping jaw assembly 300 is in abutment with the side of the PCB substrate 910 on which the electronic element is arranged at the edge, and the positioning groove 411 of the second clamping jaw assembly 400 clamps the other side of the PCB substrate 910.

[0043] In the embodiment, the positioning groove 411 is hard connected with the PCB board to improve the clamping accuracy of the PCB board on the PCB board clamping jaw, so as to ensure the installation accuracy during assembly of the PCB board.

[0044] In the embodiment, the positioning groove 411 is a V-shaped groove, which can guide the insertion of the PCB substrate 910. Of course, other shapes of grooves can also be used to adapt to the PCB board.

[0045] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the second clamping jaw assembly 400 includes two second clamping jaw parts 420 arranged in sequence along a second direction, and the second direction is arranged perpendicular to the first direction. Along the second direction, the distance between the two second clamping jaw parts 420 is greater than the length of the flexible abutting part 310. So that in the front projection of the Z direction, the first clamping jaw assembly 300 and the two second clamping jaw parts 420 form a triangular clamping structure, which is more stable for clamping the PCB board.

[0046] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the second clamping jaw assembly 400 further includes a second linear module 430, and the second linear module 430 extends along the second direction. The second clamping jaw part 420 can move along the second direction (Y direction in the figure) under the drive of the second linear module 430.

[0047] Among them, the relative motion between different second clamping jaw parts 420 can also be opposite motion, and then adjust the distance between different second clamping jaw parts 420, or adjust the position of the second clamping jaw part 420 relative to the first clamping jaw assembly 300, in order to adjust the clamping position for different PCB boards.

[0048] In the embodiment, the second linear module 430 can be a sliding table module, which can realize the relative motion between different second clamping jaw parts 420 or the motion of the second clamping jaw part 420 relative to the first clamping jaw assembly 300 at the same time. Of course, the second linear module 430 can also be a positive and negative screw rod module, a double-head air cylinder, etc. At this time, only the distance between different second clamping jaw parts 420 can be adjusted.

[0049] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the first clamping jaw assembly 300 includes a third linear module 320 and a first clamping jaw part 330, and the first clamping jaw part 330 moves along the second direction under the drive of the third linear module 320.

[0050] By controlling the movement of the first gripper 330 through the third linear module 320, combined with the movement of the second gripper 420 controlled by the second linear module mentioned above, the position of the first gripper 330 and the second gripper 420 relative to the gripper substrate 100 can be adjusted. This allows for adjustment of the clamping position for PCBs with partially eccentric designs (PCBs where some electronic components are concentrated, causing the center of gravity to be far from the center of the PCB substrate 910). This ensures that the center of gravity of the PCB is within the coverage area of ​​the first gripper 330 and the second gripper 420 on the orthogonal projection along the Z direction shown in the figure, thereby improving clamping stability.

[0051] In this embodiment, the specific selection of the third linear module 320 can refer to the first linear module 200 or the second linear module 430 mentioned above.

[0052] In some embodiments, combined with Figure 1 and Figure 2 As shown, the second gripper assembly 400 further includes a second elastic element 440, which is connected to the second gripper portion 420. The second gripper portion 420 is adapted to move along a third direction (Z direction in the figure) under the drive of the second elastic element 440. The third direction is perpendicular to the first direction (X direction in the figure) and the second direction (Y direction in the figure). The first gripper assembly 300 further includes a first elastic element 340, which is connected to the first gripper portion 330. The first gripper portion 330 is adapted to move along a third direction under the drive of the first elastic element 340.

[0053] During the PCB installation process, the first elastic element 340 and the second elastic element 440 can elastically contract to compensate for the angular or positional deviation between the PCB and the installation position. This not only protects the PCB during the buffering hard insertion process but also improves the installation accuracy of the PCB.

[0054] In this embodiment, the first elastic element 340 and the second elastic element 440 can be springs, or they can be silicone pads, pistons, etc.

[0055] In some embodiments, combined with Figure 1 and Figure 2 As shown, one of the first gripper assembly 300 or the second gripper assembly 400 is provided with a detachable positioning block 410, and the positioning block 410 is provided with a positioning groove 411.

[0056] In this embodiment, the positioning blocks 410 with different positioning groove widths 411 are replaced to adapt to PCB substrates 910 with different thicknesses.

[0057] In some embodiments, combined with Figure 1 and Figure 2As shown, the PCB gripper further comprises a synchronous assembly 500, the synchronous assembly 500 comprising a driving member 510, a driving wheel 520, a synchronous belt 540 and a driven wheel 530, the driving wheel 520 and the driven wheel 530 being rotationally arranged on the gripper base plate 100, the driving wheel 520 being connected with the driven wheel 530 through the synchronous belt 540, the driving wheel 520 driving the synchronous belt 540 to move around the driving wheel 520 and the driven wheel 530 under the driving of the driving member 510; the belt surfaces of the synchronous belt 540 located on both sides of the driving wheel 520 are respectively connected with the first gripper assembly 300 and the second gripper assembly 400.

[0058] In the embodiment, the driving member 510 drives the driving wheel 520 to rotate and drives the synchronous belt 540 to move, at this time, the movement directions of the belt surfaces of the synchronous belt 540 located on both sides of the driving wheel 520 are opposite, and each drives the corresponding first gripper assembly 300 or the second gripper assembly 400 to move, thereby realizing synchronous closing or separating of the first gripper assembly 300 and the second gripper assembly 400, ensuring that the first gripper assembly 300 and the second gripper assembly 400 simultaneously clamp or release the PCB board, realizing accurate clamping of the PCB board and avoiding the situation that the PCB board is damaged due to too large unilateral force.

[0059] In the second aspect, the utility model embodiment provides a PCB board carrying mechanism, comprising the PCB gripper of the above-embodied example.

[0060] Specifically, the PCB gripper can be connected with a driving assembly, such as a mechanical arm, a moving module and the like, and the PCB gripper is driven to move by the driving assembly to grab or place the PCB board at a specific point.

[0061] In the third aspect, the utility model embodiment provides a PCB board assembling equipment, comprising the PCB gripper or the PCB board carrying mechanism of the above-embodied example.

[0062] The utility model embodiments are described in detail above in combination with the drawings, but the utility model is not limited to the above-embodied examples, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
