Description

Technical Field

[0001] This utility model relates to the technical field of devices for processing ultra-short grooves, specifically an auxiliary positioning device for processing ultra-short grooves. Background Technology

[0002] Ultra-short slots are formed by drilling multiple overlapping circular holes. During the drilling process, since one side has already been drilled, uneven force on both sides of the drill bit can easily occur, causing the ultra-short slot holes to deform, become larger or smaller, affecting the yield of PCB boards. At the same time, due to the deviation of the drilling equipment and the alignment tolerance, the center position of the drilled hole and the pad on the film may be offset, resulting in off-center holes, reducing the effective area of ​​the pads and increasing the risk of manufacturing defects. However, the existing technology lacks an auxiliary positioning device for ultra-short slot processing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary positioning device for ultra-short groove machining, thus solving the problem of the lack of such devices in the prior art.

[0004] To achieve the above objectives, this utility model provides an auxiliary positioning device for ultra-short slot processing, comprising two bases for mounting on an external ultra-short slot processing device. The two bases are arranged opposite to each other and connected by a guide rail. A sliding seat is slidably disposed on the guide rail along the opening direction of the guide rail. A template for attaching to the external PCB board to be processed is detachably connected to the sliding seat. The template has a preset groove adapted to the size of the ultra-short slot to be processed. The sliding seat is provided with a fixing member for fixing the template and a first adjusting member for adjusting the relative height between the template and the external PCB board. The base is provided with a second adjusting member for adjusting the position of the template relative to the external PCB board.

[0005] The advantages of adopting the above technical solution are: the operator fixes the template with the preset groove on the sliding seat with the fastener, and then adjusts the position between the template and the PCB board to be processed by the second adjusting component so that the template is above the PCB board. Then, the relative height between the template and the PCB board is adjusted by the first adjusting component so that the template is attached to the PCB board and the preset groove on the template coincides with the position to be processed on the PCB board. Then, the PCB board can be processed by the processing equipment to form the ultra-short groove.

[0006] The present invention further includes the following: the fixing component includes three vacuum generators for communicating with the output end of an external compressed air source device. The three vacuum generators are arranged on the sliding seat, and the negative pressure adsorption end of the vacuum generator is in contact with the end face of the template.

[0007] The advantages of adopting the above technical solution are as follows: In the above technology, the three vacuum generators are set on the sliding base. When it is necessary to fix the template, it is only necessary to start the vacuum generator. The tail of the vacuum generator generates an adsorption hole and adsorbs and connects with the surface of the template, thereby realizing the fixed connection between the template and the vacuum generator, and indirectly realizing the mating connection between the template and the sliding base. The vacuum generator in the above technology is existing technology. It works in conjunction with an external compressed air source to generate negative pressure adsorption force. The compressed air source is a negative pressure air pump, etc., thereby realizing the adsorption of the template. Since it is existing technology, its specific functions and structure will not be described in detail.

[0008] The present invention further includes: a fixing hole is provided on the sliding seat corresponding to the vacuum generator position, and a connecting shaft is threaded into the fixing hole. The three connecting shafts correspond one-to-one with the three vacuum generators, and the end of each connecting shaft is connected to the top outer wall of the vacuum generator. The connecting shaft is the first adjusting component, and the connecting shaft is set perpendicular to the template.

[0009] The advantage of adopting the above technical solution is that when it is necessary to adjust the relative height between the template and the external PCB board, simply rotate the connecting shaft so that the connecting shaft moves down in the fixing hole, which will drive the vacuum generator to move down, and then drive the template to move down through the vacuum generator, so that the template is attached to the PCB board.

[0010] The present invention further comprises: the three vacuum generators are arranged in a triangular shape on the sliding base.

[0011] The advantage of adopting the above technical solution is that the three vacuum generators are distributed in a triangular shape on the sliding seat, thereby improving the adsorption strength of the template.

[0012] The present invention further comprises: the guide rail is composed of two oppositely arranged sliding shafts, and the sliding seat is provided with sliding holes corresponding to the positions of the two sliding shafts. The two sliding shafts are threadedly connected to their respective corresponding sliding holes. The second adjusting component includes a drive motor disposed on one of the bases and used to drive the sliding shafts to rotate axially.

[0013] The advantages of adopting the above technical solution are as follows: In the above technology, the sliding seat moves on two sliding shafts by driving the sliding shaft to rotate axially through the drive motor. That is, when the sliding shaft rotates, it is in a state of immobility relative to the base. However, the sliding hole on the sliding seat is threadedly connected to the sliding shaft, so that the sliding seat moves on the sliding shaft when the sliding shaft rotates. This movement principle is similar to the principle of lead screw transmission. This allows for adjustment of the position of the template relative to the external PCB board to be processed, thereby improving practicality and applicability. In the above technology, the number of drive motors can be limited according to actual design and installation requirements. When there is only one drive motor, its output end is connected to one of the sliding shafts. The other sliding shaft can be connected to the first sliding shaft through belt drive or chain drive. This connection method is existing technology, so it will not be described in detail. When there are two drive motors, one motor can drive one sliding shaft to rotate, so that the two sliding shafts rotate synchronously.

[0014] The present invention further includes: the bottom of the base is detachably provided with several connecting bolts for threaded connection with pre-embedded holes on external processing equipment.

[0015] The advantages of adopting the above technical solution are: the setting of connecting bolts in the above technology is used to realize the connection between the base and the external processing equipment, thereby improving the connection strength between the two; at the same time, the holes opened in advance on the external processing equipment are pre-embedded holes or preset holes. These holes can be opened manually and are conventionally opened, so the specific opening method will not be elaborated in detail. Attached Figure Description
