[0034] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0035] First embodiment

[0036] Please refer to Figure 1 ,in, Figure 1The present invention provides a schematic structural diagram of a first embodiment of an automatic needle matching device for a drill bit in the PCB industry. An automatic needle matching device for a drill bit in the PCB industry includes:

[0037] A workbench 1 and a small stand 2, wherein the workbench 1 is provided with a first needle matching area 3, a second needle matching area 4 and a matched needle area 5;

[0038] A first mounting frame 6, which is mounted on the surface of the workbench 1 and located between the first needle matching area 3 and the second needle matching area 4, a box removal clamp 7 is installed at the bottom of the first mounting frame 6, a second mounting frame 8 is mounted on the surface of the workbench 1 and located above the needle matching area 5, and a needle matching clamp 9 is installed at the bottom of the second mounting frame 8;

[0039] A first conveyor belt 10 is installed on the left side of the surface of the workbench 1, a second conveyor belt 11 is installed on the surface of the workbench 1 and located on the right side of the first conveyor belt 10, an empty box waiting area 12 is provided on the surface of the workbench 1, and a third conveyor belt 13 is installed on the surface of the workbench 1 and located on one side of the empty box waiting area 12.

[0040] The first conveyor belt 10 and the second conveyor belt 11 can convey the empty boxes to the empty box waiting area 12, the third conveyor belt 13 can convey the empty boxes in the empty box waiting area 12 to the inside of the needle-matching area 5, and the fourth conveyor belt 14 is used to facilitate the conveyance of the boxes that have been matched with needles.

[0041] A fourth conveyor belt 14 is installed on the surface of the workbench 1 and above the first conveyor belt 10 .

[0042] A stacker 15 is disposed inside the small warehouse 2 .

[0043] The equipment is divided into three modules: "small warehouse 2, needle matching area, and needle matching area 5";

[0044] Small vertical warehouse 1: The drill bits of small vertical warehouse 1 are automatically transported into the warehouse by the large vertical warehouse to store the commonly used drill bits needed for needle matching;

[0045] Needle matching area: The needle matching area has two first needle matching areas 3 and second needle matching areas 4. The small vertical warehouse outputs the drill bit box through the box grab 7 above the platform; at the same time, the needle matching area is divided into the first needle matching area 3 and the second needle matching area 4. When the first needle matching area 3 is matching needles, the second needle matching area 4 can move to the other end to feed and replenish empty boxes. The two do not affect each other, which provides equipment operation time;

[0046] Needle-matched area 5: The drill bit in needle-matched area 5 is subjected to single-point needle insertion through the mechanical clamping module in the needle-matching area to the empty box stored in the needle-matching area 5. According to the drill bit related information in the drill bit matching list of each material number, the drill bit is clamped from the matching area to the drill bit tray in the needle-matching area 5 through the mechanical clamping module (6 pieces) according to the requirements in the list. The boxes to be matched are automatically transported, and the empty boxes are replenished by two methods: discharging materials from the empty boxes in the first needle-matching area 3 and the second needle-matching area 4 and manually loading empty boxes.

[0047] Homework

[0048] By importing the drill list of matching needle material numbers (multiple material numbers can be imported at one time, and the inventory of drills in the system can be calculated to see whether it meets the matching needle demand);

[0049] The system calculates the number of drill bits temporarily stored in the small vertical warehouse and the needle matching area of ​​the needle matching machine according to the list to see if they meet the needle requirements; if they do, the needles are matched in sequence according to the list contents; if not, the corresponding drill bits are adjusted from the large vertical warehouse.

[0050] Drill bits with a diameter of 50 or more (or multiples of 50) are dispatched directly from the large warehouse without passing through the needle matching machine. Only drill bits with a diameter of less than 50 are dispatched from the needle matching machine area.

[0051] The maximum number of needles for a single time is 6 axes (can be less than 6 axes). At the same time, according to the drill bit diameter requirements, the drill bit with a diameter of more than 3.175 should be identified and a black drill bit needle disc should be used;

[0052] The operation method is to first complete the first cutter disc of the same axis and then complete the needle matching of the second or third cutter disc, and finally complete the delivery. The needle matching material number, the needle matching drill box ID code and the needle matching drill information are bound to complete the delivery of the current material number.

[0053] Compared with the related art, the automatic needle matching device for drilling nozzles in the PCB industry provided by the present invention has the following beneficial effects:

[0054] The present invention provides an automatic needle matching device for drill bits in the PCB industry. A first needle matching area 3, a second needle matching area 4 and a matched needle area 5 are respectively arranged on a workbench 1, and are used in conjunction with a first mounting frame 6 with a box removal clamp 7 and a second mounting frame 8 with a needle matching clamp 9. The device can replace human needle matching, reduce repeated needle matching actions of human, and reduce the time for finding drill bits; reduce the time for human counting and save labor costs;

[0055] To achieve the traceability of needle matching, the system's scheduling records can be used to trace the drill bit from new needle feeding to scrapping, including the process grinding and process use;

[0056] Through the needle matching of the equipment, the chance of contact between personnel and drill bits is reduced, and occupational injuries caused by needle matching are reduced.
