[0001] This utility model relates to the technical field of PCBA boards, specifically a PCBA board with high-density wiring for robots. Background Technology
[0002] PCBA, or Printed Circuit Board Assembly, is an important part of electronic circuit design. It is not just a simple printed circuit board (PCB), but rather the mounting of electronic components (such as surface mount components (SMT) and through-hole components (DIP)) onto the PCB and forming a complete circuit system through processes such as soldering.
[0003] Currently, when soldering electronic components onto a PCB board, a clamping mechanism is needed to fix the PCB board. The clamp is usually clamped at the edge of the PCB board. Although this can fix the PCB board, the clamping part is prone to deformation or even damage due to pressure, which leads to an increase in the defect rate. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a PCBA board with high-density wiring for robots.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] As a preferred embodiment of this utility model, the connecting assembly includes a fixed cylinder and a connecting rod. The fixed cylinder has sliding holes at both ends that slide with the connecting rod. A retaining sleeve that slides on the inner wall of the fixed cylinder is fitted onto the connecting rod.

A cap is connected to one end of the connecting rod, and a connecting block is connected to the other end, which is arranged crosswise with the connecting rod. A guide post is connected to one end of the connecting block, and both the upper frame and the elastic frame have mounting through holes for installing the fixed cylinder.
[0008] As a preferred technical solution of this utility model, one end of the fixed column is provided with a mating groove that cooperates with the connecting rod and the connecting block, one side of the mating groove is connected to a receiving groove, the inner wall of the receiving groove is connected to a limiting groove that slides with the guide column, and one end of the mating groove is connected to a guide groove that communicates with the limiting groove.
[0009] As a preferred technical solution of this utility model, the PCBA board body has through holes at all four top corners, and positioning cylinders are provided in the through holes.
[0010] As a preferred technical solution of this utility model, the upper frame and the lower frame are each provided with four positioning holes that cooperate with the positioning cylinder.

[0013] The beneficial effects of this utility model are:
[0014] 1. This type of robot uses a high-density wiring PCBA board. The upper frame, elastic frame and lower frame protect the periphery of the PCBA board body, thereby effectively avoiding deformation or even damage to the periphery of the PCBA board body caused by clamping. The elastic frame also plays a buffering role, which can reduce the impact on the PCBA board body when it is accidentally dropped.
[0015] 2. This type of robot uses a high-density wiring PCBA board. After the connecting rod and connecting block are inserted into the receiving groove through the mating groove, the cap is rotated to allow the guide post to enter the guide groove from the limiting groove and move along the guide groove until it can no longer move. At this point, the connecting block is misaligned with the mating groove. Then the cap is released, and the connecting rod is stabilized by the clamping spring that tightly presses against the clamping sleeve, thereby completing the connection between the upper frame and the lower frame. The operation is convenient and faster than the traditional bolt connection method. It is also beneficial for the later replacement of the anti-deformation structure or the PCBA board body.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a high-density wiring PCBA board for robots, comprising a PCBA board body 1. The outer side of the PCBA board body 1 is provided with an anti-deformation structure, which includes an upper frame 2, an elastic frame 3, and a lower frame 5. The elastic frame 3 is disposed between the upper frame 2 and the lower frame 5 and is fixed to the upper frame 2 by adhesive. A plurality of fixing posts 7 are provided on one side of the lower frame 5. A plurality of connecting components 8 that cooperate with the fixing posts 7 are provided on the upper frame 2. The upper frame 2 is detachably connected to the lower frame 5 through the connecting components 8 and the fixing posts 7. The elastic frame 3 can be made of elastic materials such as rubber and silicone to provide cushioning and protection.
[0027] The connecting assembly 8 includes a fixed cylinder 81 and a connecting rod 82. Both ends of the fixed cylinder 81 are provided with sliding holes that slide with the connecting rod 82. The connecting rod 82 is fitted with a retaining sleeve 87 that slides with the inner side wall of the fixed cylinder 81. A retaining spring 85 is also fitted on the outside of the connecting rod 82. The retaining spring 85 is clamped between the inner bottom wall of the fixed cylinder 81 and the retaining sleeve 87. One end of the connecting rod 82 is connected to a cap 86, and the other end is connected to a connecting block 83 that is arranged crosswise with the connecting rod 82. One end of the connecting block 83 is connected to a guide post 84. The upper frame 2 and the elastic frame 3 are both provided with mounting through holes for installing the fixed cylinder 81.
[0028] After the connecting rod 82 and the connecting block 83 pass through the mating groove 71 and are inserted into the receiving groove 74, the cap 86 is rotated so that the guide post 84 enters the guide groove 72 from the limiting groove 73 and moves along the guide groove 72 until it can no longer move. At this point, the connecting block 83 is disengaged from the mating groove 71. Then the cap 86 is released, and the connecting rod 82 is stabilized by tightly pressing the clamping spring 85 against the clamping sleeve 87, thereby completing the connection between the upper frame 2 and the lower frame 5. The operation is convenient and faster than the traditional bolt connection method, which is beneficial for the later replacement of the anti-deformation structure or the PCBA board body 1.
[0029] The fixed post 7 has a mating groove 71 at one end that mates with the connecting rod 82 and the connecting block 83. A receiving groove 74 is connected to one side of the mating groove 71. A limiting groove 73 that slides with the guide post 84 is connected to the inner wall of the receiving groove 74. A guide groove 72 that communicates with the limiting groove 73 is connected to one end of the mating groove 71. The receiving groove 74 is used to receive the connecting rod 82. The mating groove 71 allows the connecting rod 82 and the connecting block 83 to be inserted into the receiving groove 74. The connecting block 83 is limited by the sliding engagement of the limiting groove 73 and the guide groove 72 with the guide post 84.
[0030] The PCBA board body 1 has through holes at its four corners, and positioning cylinders 4 are installed in the through holes. The positioning cylinders 4 and the positioning holes are used to position the upper frame 2 and the lower frame 5. In addition, the positioning cylinders 4 can also be used to install bolts to fix the PCBA board to the equipment.
[0031] The upper frame 2 and the lower frame 5 are each provided with four positioning holes that cooperate with the positioning cylinder 4. The four positioning holes are arranged in a rectangular shape. At least two sets of symmetrically distributed anti-slip strips 6 are provided on the side of the upper frame 2 and the lower frame 5 away from the elastic frame 3. The anti-slip strips 6 are used to increase the friction between the anti-slip strips and the clamp, thereby reducing the probability of the PCBA board sliding.
[0032] Among them, such as Figure 7 As shown, the PCBA board body 1 includes a base layer 11 and a top layer 15. A plurality of conductive layers 16 and insulating layers 17 are provided between the base layer 11 and the top layer 15. Copper lines are provided on the base layer 11, the top layer 15 and the conductive layers 16. The insulating layer 17 is provided on one side of the conductive layers 16 and serves as an insulating layer.
[0033] The PCBA board body 1 is coated with a solder mask layer 13 on both the top and bottom sides. The PCBA board body 1 has a number of vias 12, blind vias 14 and buried vias 18. Copper lines can be arranged on the base layer 11, the top layer 15 and the conductive layer 16. The solder mask layer 13 is used to prevent parts that should not be soldered from being connected by solder, which is beneficial for soldering electronic components by reflow soldering. The number of vias 12 can be reduced by the blind vias 14 and the buried vias 18, thereby increasing the wiring density.
[0034] During operation, the positioning cylinder 4 is used to position the upper frame 2 and the lower frame 5 by interlocking with the positioning hole, and the upper frame 2, the lower frame 5 and the PCBA board body 1 are assembled together. At this time, the connecting rod 82 and the connecting block 83 will pass through the mating groove 71 and be inserted into the receiving groove 74. Then, the cap 86 is rotated so that the guide post 84 enters the guide groove 72 from the limiting groove 73 and moves along the guide groove 72 until it can no longer move. Then, the connecting block 83 is disengaged from the mating groove 71. Then, the cap 86 is released, and the connecting rod 82 is stabilized by tightly pressing the clamping spring 85 of the clamping sleeve 87, thereby completing the connection between the upper frame 2 and the lower frame 5. The upper frame 2, the elastic frame 3 and the lower frame 5 protect the periphery of the PCBA board body 1, thereby effectively avoiding deformation or even damage to the periphery of the PCBA board body 1 caused by the clamping of the fixture.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
