Description

Technical Field

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

[0002] A drill 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. Drills are usually made of carbide or high-speed steel, with sharp cutting edges, and can perforate the surface of PCB carriers to connect circuits and fix electronic components. The design of the drill enables it to accurately drill holes in a small space, reducing damage to surrounding materials. Drills 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 drills refer to drills with a drilling diameter of about 0.03 mm. When drills are produced and processed, in order to facilitate the rapid processing of drills of different sizes, a large number of drill blanks need to be divided so that different positioning devices and grinding devices can be used for subsequent processing of the drills. However, it still has the following disadvantages in actual use:

[0003] When a drill bit production factory needs to produce a large number of drill bits and the number of drill bits of each type is small, drill bits of multiple sizes are usually produced and processed at the same time. Therefore, the processed drill bit blanks need to be divided at the same time to facilitate the next step of processing. The division is often performed manually by the staff. However, the size of the micro drill bit is difficult to quickly distinguish by the naked eye, and the operation is time-consuming and laborious. In addition, since the size of the micro drill bit is very small, manual division is likely to damage the drill bit blank, reducing the processing efficiency.

[0004] After the micro drill is processed into a blank, it is usually necessary to sort the blank before it is transported to the processing device so that the end that needs to be polished is in the same direction to facilitate subsequent processing. However, manual operation is time-consuming and labor-intensive, and the structures that can be used to adjust the direction of the blank mostly operate by driving the blank to vibrate, which is difficult to apply to the relatively fragile micro drill blank. Utility Model Content

[0005] The utility model aims to provide an automatic material dividing mechanism for micro drill bits, which solves the problems of manual material dividing being time-consuming and labor-intensive and prone to errors when dividing and sorting micro drill bit blanks through a limit discharging frame, a limit driving frame and a feed box, and the problem that the tip of the micro drill bit blank is fine and easily damaged during material dividing and sorting by vibration.

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

[0007] The utility model discloses an automatic material distribution mechanism for a micro drill, comprising a limit discharging frame, a limit driving frame and a feed box, wherein a plurality of discharging ports are provided through the bottom of the limit discharging frame, a limit plate is slidably engaged in each of the discharging ports, a limit driving frame is fixedly engaged in the limit discharging frame, a plurality of elastic support rods are rotatably engaged in the inner edge of the limit driving frame, a video recording component is suspended from the top of the limit driving frame, a push plate is attached to one end of the limit driving frame, a reversing support rod is arranged in the limit driving frame, and a feed box is fixedly engaged in the top of the limit driving frame;

[0008] The micro drill blanks that enter the limit drive frame in sequence through the feed box can be preliminarily sorted through a plurality of elastic support rods, so that a micro drill blank is supported between two adjacent elastic support rods, which is convenient for the subsequent sorting and sorting of the micro drill blanks. Micro drill blanks of different sizes can be discharged separately through a plurality of discharge ports, which is convenient for the subsequent processing of different micro drills and improves the automation degree of the dividing mechanism. The limit plate can prevent inappropriate blanks from being discharged through the corresponding discharge port, thereby ensuring the accuracy of the material division. After the blanks are discharged through the discharge box, they are The video recording component can record the blank, and the size of the micro drill can be quickly judged through the photo, which is convenient for subsequent material division. There is no need to judge by the naked eye, which improves the efficiency of material division. The blank can be pushed to one end of the limit drive frame through the push plate, and the direction of the micro drill blank can be adjusted through the reversing support rod, so that the direction of a large number of blanks can be unified, which is convenient for subsequent devices to process the blank. The direction of the blank is adjusted by driving the blank to rotate horizontally, which avoids adjusting the direction of the blank through the vibration structure, avoids damage to the tip of the micro drill blank, and ensures processing efficiency.

[0009] Furthermore, a non-slip base is clamped and fixed around the bottom of the position-limiting discharge rack, a plurality of discharge ports are arranged in parallel, and the elastic support rod is suspended from the top of the discharge port;

[0010] The anti-slip base can improve the stability of the automatic material distribution mechanism structure, and the limit discharging rack can limit the blanks moved between the limit discharging rack and the limit driving rack, ensuring that one blank is always located between two adjacent elastic support rods, thereby ensuring the stability of material distribution and sorting.

[0011] Furthermore, one end of each of the limit plates is clamped with a first telescopic rod, the other end of the first telescopic rod is slidably clamped with a discharge cylinder, and one end of one of the discharge cylinders is clamped in a discharge port;

[0012] The discharge cylinder can drive the movement of the limit plate to open or close the discharge port to prevent unsuitable blanks from being discharged through the corresponding discharge port, thereby ensuring accurate material distribution. Blanks of different sizes can be discharged separately through multiple discharge ports, which is convenient for subsequent processing of different micro drills and improves the degree of automation of the material distribution mechanism.

[0013] Further, a driving motor is inserted through one end of the limit drive frame, a transmission belt is rotatably connected to one side of the limit drive frame, one end of the plurality of elastic support rods is connected to one side of the transmission belt, the driving motor is connected to the transmission belt through the limit drive frame, a positioning plate is welded and fixed to one end of the top of the limit drive frame, a support plate is welded and fixed to the inside of the limit drive frame, a support frame is welded and fixed to the top of the limit drive frame, and the video recording component is fixed to the top of the support frame;

[0014] The driving motor drives the transmission belt to rotate, which further moves the multiple elastic support rods, driving the multiple blanks to move, so that a large number of blanks can be fed, video-divided, sorted and discharged in sequence through the automatic dividing mechanism. The blanks can be recorded by the video component, and the size of the micro drill can be quickly determined by the photo, which is convenient for subsequent dividing. There is no need to judge by the naked eye, thereby improving the dividing efficiency and the degree of automation of the automatic dividing mechanism.

[0015] Further, a positioning cylinder is clamped on one side of the limit driving frame, and the positioning cylinder is located on the other side of the limit driving frame relative to the positioning plate. A second telescopic rod is slidably clamped on one end of the positioning cylinder, and the push plate is clamped on the other end of the second telescopic rod relative to the positioning cylinder. A pressure sensing component is clamped and fixed on one side of the push plate, and the second telescopic rod is inserted through one side of the limit driving frame.

[0016] The positioning cylinder can drive the push plate to move and push the blank so that one end of the blank fits against one side of the positioning plate. The pressure of the push plate on the blank can be monitored by the pressure sensing component to avoid damage to the micro drill blank caused by excessive pressure.

[0017] Furthermore, a lifting cylinder is clamped on the top of the support plate, a third telescopic rod is slidably clamped on the top of the lifting cylinder, a rotating motor is clamped on the top of the third telescopic rod, the reversing support rod is clamped on the top of the rotating motor, a supporting groove is provided on the top of the reversing support rod, the reversing support rod is inserted through and connected between two adjacent elastic support rods, and the push plate is located between the video recording assembly and the reversing support rod;

[0018] When the video monitoring detects that the direction of the micro drill blank is wrong, when the blank moves to the top of the reversing support rod, the lifting cylinder drives the reversing support rod to move upward, supports and positions the blank through the support groove, and makes the blank separate from the top of the elastic support rod. The reversing support rod and the blank are driven by the rotating motor to rotate, and the angle of the blank is adjusted, thereby avoiding adjusting the direction of the blank through the vibration structure and avoiding damage to the tip of the micro drill blank, ensuring processing efficiency and making the direction of a large number of blanks unified, which is convenient for subsequent devices to process the blanks.

[0019] Furthermore, a plurality of elastic slow-flow plates are fixed from top to bottom in the feed box, a feed opening is provided through one side of the bottom of the feed box, the feed opening is suspended from the top of the elastic support rod, and the video recording assembly is located between the feed box and the push plate;

[0020] When the blanks fall into the feed box, the elastic slow-flow plate can slow down and separate a large number of blanks, avoiding collisions caused by multiple blanks moving directly downward under the action of gravity, avoiding damage to the tip of the blank, and preliminarily sorting the blanks to prevent the ends of the blanks from entering the top of the limit drive frame downward. The elastic support rod can reduce the shock of the falling blanks to ensure the quality of the micro drill. Only one blank can fall from the discharge port at a time, so that one micro drill blank is supported between two adjacent elastic support rods, which is convenient for subsequent sorting and separation of the micro drill blanks.

[0021] The utility model has the following beneficial effects:

[0022] The utility model provides a limit discharging frame and a limit driving frame, which solves the problem that when a factory producing drill bits needs to produce a large number of drill bits and the number of drill bits of each type is small, drill bits of various sizes are usually produced and processed at the same time, so the processed drill bit blanks need to be divided at the same time to facilitate the next step of processing. The division is often performed manually by staff, but the size of the micro drill bit is difficult to quickly distinguish by the naked eye, and the operation is time-consuming and laborious. In addition, since the size of the micro drill bit is very fine, manual division is likely to damage the drill bit blank, thereby reducing the processing efficiency. When the material enters the upper side of the limit driving frame, multiple blanks are separated by multiple elastic support rods, and the multiple elastic support rods and the blanks are driven to move by a driving motor. The blanks are recorded by the video recording assembly when passing through the bottom side of the video recording assembly. The size of the micro drill can be quickly judged by photos, and there is no need to judge by the naked eye, thereby improving the material separation efficiency. When the drill blank moves to the upper side of the corresponding discharge port, the limit plate slides to open the discharge port to discharge the drill blank, so that micro drill blanks of different sizes are discharged through different discharge ports and proceed to the next step of processing, thereby improving the degree of automation of the material separation mechanism.

[0023] The utility model solves the problem that after the micro drill bit is processed into a blank and before it is transported to the processing device, the blank usually needs to be sorted so that the end that needs to be polished is in the same direction for subsequent processing, but manual operation is time-consuming and laborious, and the structures that can be used to adjust the direction of the blank are mostly operated by driving the blank to vibrate, which is difficult to be applied to relatively fragile micro drill bit blanks. After the blank is poured into the feed box, a large number of blanks can be slowed down and separated by an elastic slow-flow plate, so that multiple blanks can be prevented from directly moving downward under the action of gravity and causing collisions. The blank is preliminarily arranged. After the blank is recorded by the video recording component, the direction of the micro drill blank is determined according to the photo. When the blank moves to one end of the push plate, the push plate is used to push the blank to adjust its position. When the blank with the wrong direction moves to the upper side of the reversing support rod, the reversing support rod can adjust the direction of the micro drill blank to unify the directions of a large number of blanks, which is convenient for subsequent devices to process the blanks. The direction of the blank is adjusted by driving the blank to rotate horizontally, which avoids adjusting the direction of the blank through a vibration structure, avoids damage to the tip of the micro drill blank, and ensures processing efficiency.
