Description

Technical Field

[0001] The utility model relates to the technical field of drill bit collection, in particular to an automatic drill bit collection device. Background Technique

[0002] As an indispensable component in modern electronic products, a circuit board (also known as a PCB) mainly functions to connect various electronic components and play a role in relay transmission. Nowadays, with the development of the times, electronic products have spread to all aspects of society and play an important role in people's daily lives. At the same time, the growing demands in all aspects of society are also driving electronic products to break through existing technologies, develop and innovate, which will inevitably put forward higher requirements for circuit board manufacturing technologies, requiring them to continuously improve performance and production efficiency.

[0003] As an important part of the circuit board production and processing process, it is very necessary to optimize and improve the drilling process. Drilling refers to drilling vias on the circuit board. The main functions of these vias are to connect each layer of the circuit and meet the needs of installation and positioning. The tool used by the drilling machine to drill these vias is a drill bit. During the drilling process, these drill bits will inevitably wear until the service life of the drill bit ends. At this time, the drill bit bar equipped with the drill bit needs to be taken out and the drill bit needs to be replaced. After taking out the drill bit bar, it is sent to the drill bit room for unified replacement. These used drill bits will be ground again according to the number of grinding times for the next use. Before grinding, the drill bits need to be pulled out from the drill bit bar. However, the number of these drill bits is too large, and the drill tip of each drill bit is very sharp, which is very inconvenient during the disassembly process and is also very easy to cause the drill bit to break.

[0004] Based on this, the utility model designs an automatic drill bit collection device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic drill bit collection device to solve the problems of easy harm to operators during collection and low collection efficiency proposed in the above background technique.

A row of semicircular grooves are distributed on the clamping plate, corresponding to the arrangement of the drill bits on the drill bit blade;

[0009] Preferably, there are two motors, installed inside the external frame, respectively connected to the storage box conveyor belt and the drill bit blade conveyor belt, providing kinetic energy for the conveyor belts;

[0010] Preferably, storage box fixing devices are installed on both sides of the storage box conveyor belt. A temporary storage platform is installed behind the storage box conveyor belt. After the storage box is filled with drill bits, it will be conveyed to the temporary storage platform for placement;

[0011] Preferably, a blade channel is arranged above the drill bit blade conveyor belt, facilitating the placement of the drill bit blade and subsequent smooth conveying. A blade collecting box is installed behind the drill bit blade conveyor belt. After the drill bits on the drill bit blade are pulled out, they will be conveyed to the blade collecting box;

[0012] Preferably, an auxiliary clamping piece is installed on the blade channel, used to clamp the drill bit blade, preventing shaking during the clamping process. The auxiliary clamping piece is controlled by a sensor. When the sensor detects that the drill bit blade reaches the specified position, it controls the auxiliary clamping piece to clamp the drill bit blade. After the clamping is completed, the drill bit blade is released. When the next drill bit blade reaches the specified position, the clamping is carried out again;

[0013] Preferably, the cleaning mechanism includes a housing, a toothed ring, a rotating plate, a pull rod, a rotating column and a gear. One end of the spring is fixedly connected to the housing.

[0015] 1. When the clamping device descends in the present utility model, the spring is compressed, and at the same time, a plurality of rotating plates move away from each other. When the clamping device descends to a suitable position, the length of the telescopic rod is controlled according to the position of the material, so that the clamping plate moves out of the outside of the cleaning mechanism, and the material passes through a plurality of rotating plates and is located between the two clamping plates. Then, the bidirectional screw is controlled to rotate, so that the clamping plate clamps the material. When the material is being clamped, a plurality of rotating plates are pulled by the toothed ring and move closer to each other. When the clamping plate clamps the material and rises, the spring gradually recovers. At this time, the wiping sponge between the plurality of rotating plates wipes the material, so that the material can be cleaned while being taken out, further ensuring the cleanliness of the material, making the equipment more diverse in use and more convenient to use.

[0016] 2. The traditional method of pulling out drill bits is to pull them out one by one manually. However, the drill bits are too slender, sharp and pointed. During the pulling process, not only are they easy to stab the fingers, but they are also very easy to break. After applying this automatic drill bit collection device, there is no need to pull out the drill bits by hand. The drill bits on the knife bar will be automatically pulled out and placed in the storage box, thereby effectively improving the production and processing efficiency, saving manpower and material resources, and accelerating the production progress.

A row of semi-circular grooves are distributed on the clamping plate 505, corresponding to the arrangement of the drill bits on the drill bit strip. An arc-shaped rubber pad is provided on the clamping plate 505;

[0029] Among them, there are two motors, installed inside the external frame 1, respectively connected to the storage box conveyor belt 6 and the drill bit strip conveyor belt 9, providing kinetic energy for the conveyor belts;

[0030] Among them, storage box fixing devices 7 are installed on both sides of the storage box conveyor belt 6, and a temporary storage platform 8 is installed behind the storage box conveyor belt 6. After the storage box is filled with drill bits, it will be transported to the temporary storage platform 8 for placement;

[0031] Among them, a strip channel 10 is arranged above the drill bit strip conveyor belt 9, facilitating the placement of the drill bit strip and subsequent smooth transportation. Behind the drill bit strip conveyor belt 9, a strip collection box 13 is installed.

[0032] Among them, an auxiliary clamping piece 11 is installed on the tool bar channel 10 for clamping the drill bit tool bar to prevent shaking during the clamping process. The auxiliary clamping piece 11 is controlled by a sensor. When the sensor detects that the drill bit tool bar reaches the specified position, it controls the auxiliary clamping piece 11 to clamp the drill bit tool bar.

[0034] Working principle:

[0035] During work, the storage box is placed on the storage box conveyor belt 6. When the storage box is conveyed to the specified position, the first sensor 701 controls the storage box conveyor belt 6 to stop, and the fixing rod 702 extends out to fix the storage box, and the storage box is ready; then the drill bit tool bar is placed on the drill bit tool bar conveyor belt 9 from the tool bar channel 10. When the second sensor 12 senses that the drill bit tool bar is conveyed to the specified position, it controls the drill bit tool bar conveyor belt 9 to stop running, and the auxiliary clamping piece 11 clamps the drill bit tool bar. At this time, the clamping device 5 starts to work. When the clamping device 5 descends, the spring 52 is compressed, and the transmission assembly 51 maintains the transmission connection between the bidirectional screw 502 and the rotating column 545. At the same time, a plurality of rotating plates 543 move away from each other. When the clamping device 5 descends to a suitable position, the length of the telescopic rod 504 is controlled according to the position of the material, so that the clamping plate 505 moves out of the outside of the cleaning mechanism 54, and the material passes through a plurality of rotating plates 543. When the material is located between the two clamping plates 505, the bidirectional screw 502 is controlled to rotate, so that the clamping plate 505 clamps the material. When the material is being clamped, a plurality of rotating plates 543 are pulled by the toothed ring 542 and move closer to each other. When the clamping plate 505 clamps the material and rises, the spring 52 gradually recovers. At this time, the wiping sponge between the plurality of rotating plates 543 wipes the material, so that the material can be cleaned while being taken out, further ensuring the cleanliness of the material, making the equipment more diverse and more convenient to use when in use;

[0036] After the clamping is completed, the piston rod in the lifting cylinder 4 rises, driving the clamping device 5 to rise. The clamping device 5 moves leftward above the storage box through the horizontal guide rail 3. At this time, the piston rod in the lifting cylinder 4 descends, and the clamping device 5 places the drill bit into the storage box and returns above the drill bit bar.

[0037] After the drill bits on the drill bit bar are clamped, the clamping piece will loosen, and the drill bit bar conveyor belt 9 will convey the drill bit bar to the tool bar collection box 13 at the rear. After the storage box is full of drill bits, the fixing rod 702 will contract, and the storage box conveyor belt 6 will convey the storage box to the temporary storage platform 8 at the rear for temporary storage.
