DETAILED DESCRIPTION

[0018] 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.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a PCB drilling positioning device, including a body 1, four support rods 101 that are symmetrical in front and back and left and right are fixedly installed on the upper surface of the body 1, and slide rails 9 are arranged between the support rods 101 on both sides of the upper surface of the body 1. A collection drawer 10 located below the support frame plate 2 is installed on the slide rail 9 for collecting waste generated by drilling with a drill bit.

[0020] A support frame plate 2 is installed on the top of the support rod 101, and two fixed rods 5 perpendicular to the inner wall are arranged inside the support frame plate 2. The two fixed rods 5 are horizontally slidably connected to multiple movable rods 6 perpendicular to their directions. The upper surface of the movable rod 6 is provided with multiple support columns 7 equidistantly arranged along the axial direction. The top of the support column 7 is provided with a rubber support pad 8, which is used to support the bottom of the PCB to prevent the drill bit from pressing down to drill a hole and causing the PCB to bend and rebound.

[0021] A downward-opening slide groove 601 is provided at the bottom of the movable rod 6 near the two ends, and the slide groove 601 and the fixed rod 5 are locked and fixed by bolts at both ends of the movable rod 6, so as to facilitate the sliding adjustment of the movable rod 6 on the fixed rod 5, and the number of movable rods 6 can also be increased and decreased according to needs. A push rod 3 is vertically fixedly installed on the upper surface of the machine body 1 at the corresponding position in the middle of both sides of the supporting frame plate 2, and the top end of the push rod 3 is fixedly connected to the clamping frame plate 4 located above the supporting frame plate 2.

[0022] A positioning groove 401 with an open front is provided at the bottom of the clamping frame 4, and anti-slip pads 11 are provided on the top of the inner wall of the positioning groove 401 and the upper surface of the supporting frame 2 to avoid damage to the upper and lower surfaces at the edge of the PCB, while also having a certain anti-slip effect. The positioning groove 401 is adapted to the shape and size of the supporting frame 2.

[0023] Working principle: The PCB is inserted from the positioning groove 401 on the front side of the clamping frame plate 4 and placed on the top of the supporting frame plate 2. The push rod 3 drives the clamping frame plate 4 to move downward, so that the positioning groove 401 limits the clamping of the PCB on the supporting frame plate 2, so that the PCB is fixed firmly and avoids shaking and deviation of the PCB during drilling. According to the size of the PCB and the drilling position, the movable rod 6 can be adjusted to avoid the drilling position of the drill bit. The support column 7 and the rubber support pad 8 on the movable rod 6 support the lower surface of the PCB to prevent the PCB from bending and rebounding due to the downward pressure of the drill bit, thereby improving the drilling accuracy.
