Description

Technical Field

[0001] The utility model belongs to the technical field of micro drill production, in particular to a clamping mechanism for micro drill detection. Background Art

[0002] A drill needle is a tool used to drill through holes or blind holes in solid materials. It is mainly used in precision processing fields such as circuit board processing. Drill needles are usually made of carbide or high-speed steel, have sharp cutting edges, and can perforate the surface of PCB carriers to connect circuits and fix electronic components. The design of the drill needle enables it to accurately drill holes in a small space and reduce damage to surrounding materials. Drill needles are mainly used in PCB manufacturing, watch manufacturing, jewelry processing and microelectronics industries. They can provide more delicate and precise operations than drill bits. Micro drill needles refer to drill needles with a drilling diameter of about 0.03 mm. After the micro drill needle is processed and formed, in order to ensure the accuracy of its size, it is usually necessary to use a detection device to detect the micro drill needle. During the detection process, in order to ensure the stability of the drill needle during the detection process and avoid deviations in the detection results due to the shaking of the drill needle, a clamping mechanism is often used to position and clamp the micro drill needle, but it still has the following disadvantages in actual use:

[0003] The utility model with announcement number CN217561350U discloses a quality inspection device for micro drills, wherein a microscopic device is fixedly connected to the upper end of a detection base, a limited sliding groove is provided on the upper surface of the detection base, an adjustment component is slidably connected to the inner cavity of the limited sliding groove, a linkage block is fixedly connected to one side of the adjustment component, a small fan is fixedly connected to the upper end of the linkage block, a lamp is fixedly connected to the upper end of the small fan, the adjustment component includes an adjustment frame, and the clamping parts of the detection equipment often need to be manually clamped by the staff, which is time-consuming and laborious to operate when inspecting a large number of micro drills, and after inspecting a batch of drills, the drills need to be disassembled before installing new drills, which reduces the inspection efficiency;

[0004] When clamping the micro drill, the staff often manually operates the clamping mechanism to clamp the drill. Since the end of the micro drill that needs to be inspected is extremely thin and cannot be shielded, it is easily damaged by accidental collision during loading and unloading. The staff is required to handle it with care and reduce the operating speed. Utility Model Content

[0005] The utility model aims to provide a clamping mechanism for detecting micro drill bits, which solves the problem that the manual loading and unloading of a large number of micro drill bits by the clamping mechanism for detecting micro drill bits is time-consuming and laborious through a support plate and a positioning frame, and the drill bits need to be disassembled before new drill bits can be installed. During the loading and unloading process, the ends of the extremely fine drill bits are easily damaged by accidental collisions, and the staff need to handle them with care, which reduces the operating speed.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a clamping mechanism for micro drill needle detection, comprising a support plate and a positioning frame, one end of the support plate is clamped and fixed with a driving frame, a rotating frame is arranged on the top of the driving frame, one end of the driving frame is clamped with a stepping motor, one end of the rotating frame is clamped with a positioning frame, a positioning airbag is clamped at the bottom of the positioning frame, and a moving cylinder is arranged at one end of the positioning frame;

[0008] The plurality of drill needles can fall into the plurality of positioning grooves of the support plate under the action of gravity. After the drill needles fall into the positioning grooves, the positioning frame is driven to rotate downward by the rotating frame, and the positioning frame is driven to move by the slider of the driving frame, so that the plurality of drill needles can be quickly sorted, and by pumping air into the positioning airbag, the positioning airbag is expanded and the plurality of micro drill needles are squeezed and positioned. The operation is simple and convenient, and the automation degree of the clamping mechanism is improved. The staff only needs to place the plurality of micro drill needles in the positioning grooves in the same direction, and the manual operation steps are relatively few, and the ends of the micro drill needles are not easily touched, thereby avoiding damage to the micro drill needles. At the same time, the movement of the micro drill needles is driven by the slider, so that the position for loading the micro drill needles can be vacated. When a batch of micro drill needles are tested by the detection device, the staff can load another batch of micro drill needles, and when a new batch of micro drill needles are sorted and positioned by the positioning frame, the staff can quickly remove the micro drill needles that have been tested, thereby improving the detection efficiency.

[0009] Furthermore, a plurality of positioning grooves are provided on the top of the support plate, a sliding groove is provided on the top of the driving frame, a threaded rod is clamped at one end of the stepping motor, one end of the threaded rod is inserted into the sliding groove, a slider is slidably clamped in the sliding groove, one end of the slider is clamped with a threaded tube, and the threaded rod is screwed to one end of the threaded tube;

[0010] The stepper motor can drive the threaded rod to rotate, further drive the slider to move along the slide slot, drive the positioning frame and the micro drill to move, organize the micro drill and move it to the detection position, thereby improving the degree of automation of the clamping mechanism. At the same time, the movement of the micro drill driven by the slider can free up the position for loading the micro drill. When a batch of micro drills is tested by the detection device, the staff can load another batch of micro drills. When the new batch of micro drills is sorted and positioned by the positioning frame, the staff can quickly remove the micro drills that have been tested, thereby improving the detection efficiency.

[0011] Furthermore, the rotating frame is rotatably connected to the top of the slider, a rotating motor is connected to one end of the bottom of the rotating frame, the other end of the rotating motor is connected to one side of the top of the slider, and a storage groove is provided on one side of the rotating frame;

[0012] The rotating motor can drive the rotating frame and the positioning frame to rotate, so that the positioning frame can clamp and position the end of the micro drill that does not need to be detected through the positioning airbag, thereby improving the automation degree of the clamping mechanism.

[0013] Furthermore, one end of the mobile cylinder is slidably connected to a telescopic rod, the other end of the telescopic rod is connected to one end of the positioning frame, and the mobile cylinder is connected to the storage groove;

[0014] The positioning frame can be driven to move by the moving cylinder. After the detection device completes the detection of one side of the drill needle, the positioning frame can be driven to move by the moving cylinder, so that the micro drill needle can rotate in the positioning groove, making it easier for the detection device to detect the drill needle at various angles.

[0015] Furthermore, an air pump is inserted and connected at one end of the positioning frame, the air pump is connected to the positioning airbag, a limiting plate is attached to one side of the positioning frame, one end of the limiting plate is attached to one side of the rotating frame, and the limiting plate is attached to the top of the support plate;

[0016] The air pump can be used to inflate the positioning airbag, causing it to expand and squeeze multiple micro drills for positioning. The operation is simple and convenient. When the positioning frame moves along the slide groove, one end of the micro drill can be limited by moving the limit plate, and multiple micro drills can be arranged to facilitate detection by the detection device.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that the clamping parts of the detection equipment often need to be clamped and installed manually by the staff, which is time-consuming and laborious when a large number of micro drills are detected, and after a batch of drills are detected, the drills need to be disassembled before new drills can be installed, thereby reducing the detection efficiency. After a batch of micro drills are placed in a plurality of positioning grooves, the rotating frame drives the positioning frame to rotate downward and drives the positioning frame to move through the movement of the slider, so that the positioning frame further drives the micro drill to move, so that the micro drill is moved to the detection position and positioned, and at the same time, the position for loading the micro drill can be vacated. When a batch of micro drills are detected by the detection device, the staff can load another batch of micro drills, and when the new batch of micro drills are sorted and positioned by the positioning frame, the staff can quickly remove the micro drills that have been detected, thereby improving the detection efficiency.

[0019] The utility model solves the problem that when a clamping mechanism clamps a micro drill, a staff member often manually operates the clamping mechanism to clamp the drill. Since the end of the micro drill that needs to be detected is extremely thin and cannot be shielded, it is easy to be damaged by accidental collision during loading and unloading, and the staff member needs to handle it with care, which reduces the operation speed. After the staff member places multiple micro drills in multiple positioning grooves in the same direction, the micro drills are moved to the detection position by moving the positioning frame and the limit plate, and the air pump is controlled to pump air into the positioning airbag to expand the positioning airbag and squeeze and position the multiple micro drills. The operation is simple and convenient, which improves the automation degree of the clamping mechanism, and the staff member only needs to place multiple micro drills in the positioning grooves in the same direction, with fewer manual operation steps, and it is not easy to contact the end of the micro drill, thereby avoiding damage to the micro drill.
