Description

Technical Field

[0001] This utility model belongs to the field of drill needle sorting technology, and in particular relates to an automatic needle box dispensing mechanism. Background Technology

[0002] A PCB, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. PCBs often require pre-drilled holes. Multiple holes are used to mount different components, and these holes need to accommodate different components, resulting in different hole diameters that require different drill bits. In existing technologies, to improve the efficiency of punching, multiple drill bits of different sizes are arranged sequentially to punch holes in the PCB simultaneously across different areas.

[0003] In a patent document with application number "CN202323116689.8" and titled "Automatic Tool Dispensing Equipment", the following technical solution is disclosed: it includes a tool magazine and a dispensing device. The tool magazine includes several tool holder conveying assemblies arranged in parallel. Several tool holders arranged in a rectangular array are loaded on the tool holder conveying assemblies. The dispensing device includes a lifting and picking mechanism, a paddle transmission mechanism, an alternating support mechanism and a paddle output assembly arranged in sequence. A tool picking mechanism is arranged above the alternating support mechanism.

[0004] The aforementioned solution employs a multi-stage transmission module system, including a lifting and picking mechanism, a paddle transmission mechanism, and an alternating support mechanism. This requires multiple positioning transitions from the tool magazine to the first positioning platform and then to the second positioning platform. The alternating support mechanism uses a nested dual-module design, the tool picking mechanism holds the tool, and finally, the paddle outputs the tool. This solution involves complex processes, a high error rate due to the nested modules, and is prone to mechanical interference during high-speed operation, resulting in low assembly efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0024] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, an automatic needle box dispensing mechanism is provided, comprising a frame 100, a needle magazine conveying mechanism 200, a rear needle box transfer module 300, a needle dispensing module 500, a front needle box transfer module 600, and a receiving tray 800. A needle magazine 1000 is located on one side of the frame 100, containing and positioning several matrix-arranged raw needle boxes of different models, each containing a drill bit of the same model. Two sets of needle magazine conveying mechanisms 200 are provided, arranged parallel to each other above the frame 100, and connected to the inlet 1010 and outlet 1011 of the needle magazine 1000, respectively. The rear needle box transfer module 300 is movably mounted on the frame 100, and a rear needle box dispensing moving module 400 is located below the rear needle box transfer module 300. The needle-matching module 500 is mounted on the frame 100 and located to one side of the rear needle-matching movable module 400. The front needle box transfer module 600 is movably mounted on the frame 100. A front needle-matching movable module 700 is located to one side of the front needle box transfer module 600. The needle-matching module 500 pairs drill bits from different types of raw material needle boxes and places them in the same empty needle box on the front needle-matching movable module 700. A receiving tray 800 is located to one side of the front needle-matching movable module 700. The front needle box transfer module 600 places full needle boxes on the receiving tray 800, and the needle boxes are then moved from the receiving tray 800 to the pickup area 180.

[0025] Action flow: The operator first inputs the raw material needle box into the tool magazine 1000 for storage via one of the tool magazine conveying mechanisms 200. The tool magazine 1000 automatically arranges multiple raw material needle boxes of different models in a matrix, with each raw material needle box containing the same model of drill bit. When a specific model of raw material needle box is needed, the tool magazine 1000 automatically moves the corresponding needle box out of the tool magazine conveying mechanism 200. The needle box transfer module 300 then moves the raw material needle box to the subsequent matching moving module 400. The subsequent matching moving module 400 drives the needle box to a suitable position, and the needle matching module 500 drives the module to pick up some drill bits from different models of raw material needle boxes on the subsequent matching moving module 400 and load them onto empty needle boxes on the preceding matching moving module 700. After the loading is completed, the front assembly moving module 700 moves to a suitable position, the front needle box transfer module 600 picks up the full needle box containing different types of drill bits, places it on the receiving tray 800, and moves it from the receiving tray 800 to the picking area 180.

[0026] Furthermore, such as Figure 3As shown, the rear needle box transplant module 300 includes a rear vertical support 310, a rear translation drive assembly 320, a rear lifting assembly 330, and a rear gripping unit 340. The rear vertical support 310 is disposed on one side of the tool magazine 1000, the rear translation drive assembly 320 is disposed on the vertical support, the rear lifting assembly 330 is connected to the drive end of the rear translation drive assembly 320, and the rear gripping unit 340 is connected to the drive end of the rear lifting assembly 330. The rear-to-be-fitted moving module 400 has several sets, all arranged in a matrix on the frame 100. The rear-to-be-fitted moving module 400 includes a rear drive cylinder 410, a needle plate 420, and a rear guide rod 430. There are two sets of rear guide rods 430, and both ends are connected to rear positioning pin seats 440. The rear drive cylinder 410 is sleeved on the two rear guide rods 430. The drive end of the rear drive cylinder 410 is connected to any one of the rear positioning pin seats 440. The needle plate 420 is installed above the rear guide rods 430. The needle plate 420 moves to the end closer to the tool magazine 1000 to form a loading position 120, and the end farther away from the tool magazine 1000 to form a fitting position 130.

[0027] Specifically, in the initial state or after receiving an instruction, the rear drive cylinder 410 actuates, pushing the needle plate 420 to the loading position 120 near the tool magazine 1000. The rear needle box transfer module 300 then places different raw material needle boxes onto the corresponding needle plate 420. After loading is complete, the rear drive cylinder 410 actuates, pulling and pushing the needle plate 420 along the guide rod to the matching position 130 away from the tool magazine 1000. This solution achieves simplicity and efficiency in needle box loading, accelerating the subsequent needle matching process.

[0028] Furthermore, such as Figure 4 As shown, the needle distribution module 500 includes needle distribution brackets 510 symmetrically arranged on both sides of the frame 100. Each needle distribution bracket 510 has a movable needle distribution pushing module 520 at its lower part, and a first needle distribution translation component 530, a second needle distribution translation component 540, a needle distribution lifting component 550, and a clamping component 560 sequentially mounted on its upper part. The drive end of the preceding component is connected to the following component to form a motion transmission chain. Specifically, the first needle distribution translation component 530, the second needle distribution translation component 540, and the needle distribution lifting component 550 are preferably linearly driven by motors. The first needle distribution translation component 530 is coarsely adjusted, the second needle distribution translation component 540 is finely adjusted, and the needle distribution lifting component 550 controls the lifting movement of the clamping component 560. Several clamping components 560 are provided, with a spacing equal to the spacing between them and the spacing between them and the spare tray 720. The clamping components 560 can be formed by the cooperation of a solenoid valve and a gripper. The needle-dispensing module 500 places the drill bits from different raw material needle boxes into the same empty needle box according to the instructions.

[0029] Furthermore, such as Figure 5As shown, the front needle box transfer module 600 includes a front upright support 610, a front translation drive assembly 620, a front lifting assembly 630, and a front gripping unit 640. The front upright support 610 is respectively disposed on both sides of the frame 100, and a movable front pushing module 650 is provided at the lower end of the front upright support 610. The front translation drive assembly 620 is provided on the front upright support 610, and the front translation drive assembly 620 is connected to the front lifting assembly 630. The front gripping unit 640 is connected to the drive end of the front lifting assembly 630. Specifically, the front translation drive assembly 620 and the front pushing module 650 are preferably motor linear drive modules, and the front lifting assembly 630 is preferably a cylinder drive module. The three components work together to enable the needle box to move stably along the three axes.

[0030] Furthermore, such as Figure 6 As shown, the front-to-be-fitted moving module 700 includes a front drive cylinder 710, a spare plate 720, a front slider 730, a front slide rail 740, and a front guide rod 750. The spare plate 720 has several groups arranged in a matrix and fixedly connected to each other. The front guide rod 750 has two groups, and both ends are connected to front positioning pin seats 760. The front drive cylinder 710 is sleeved on the two front guide rods 750, and the drive end of the front drive cylinder 710 is connected to any one of the front positioning pin seats 760. The front drive cylinder 710 is connected to the front slider 730, and the front slider 730 is slidably connected to the front slide rail 740 on the frame 100. The spare plate 720 forms a needle-fitting position 140 on the side near the needle-fitting module 500 and a full-material position 150 on the side away from the needle-fitting module 500. Specifically, the front drive cylinder 710 actuates, pushing the common reserve tray 720 (carrying empty needle boxes) to move in parallel to the needle distribution position 140 near the needle distribution module 500. The needle distribution module 500 then sequentially places different types of drill bits into the corresponding empty needle boxes on the reserve tray 720. Once the current needle box is filled with a full needle box to form the required drill bits, the front drive cylinder 710 actuates, pushing the reserve tray 720 to a full position 150 away from the needle distribution module 500. The front needle box transfer module 600 then picks up the full needle box and moves it to the receiving tray 800. This specifically includes two sets of front drive cylinders 710, each set of front drive cylinders 710 having six sets of reserve trays 720, allowing six empty needle boxes to be distributed simultaneously.

[0031] Furthermore, such as Figure 7As shown, the front-to-be-fitted moving module 700 also includes a front pneumatic component 770. One side of the spare tray 720 is connected to the front pneumatic component 770, and the drive end of the front pneumatic component 770 abuts against the empty needle box. The spare tray 720 has a front opening 780 on the side away from the front pneumatic component 770. A push-and-position member 790 is also provided between the front-to-be-fitted moving module 700 and the rear-to-be-fitted moving module 400, and the drive end of the push-and-position member 790 extends into the corresponding front opening 780 and abuts against the empty needle box. Specifically, when the spare tray 720 moves to the needle fitting position 140, the drive end of the front pneumatic component 770 extends out, pushing the empty needle box away from itself and abutting against one side of the empty needle box. At the same time, the drive end of the push-and-position member 790 extends out, enters the spare tray 720 through the front opening 780, and abuts against the other side of the empty needle box. The two work together to precisely position and clamp the empty needle box at the predetermined position on the spare plate 720.

[0032] Furthermore, such as Figure 8 As shown, the take-up tray 800 has several output positions 160 arranged in a matrix above it. The front needle box transfer module 600 places full needle boxes in the output positions 160. Below the take-up tray 800 is a tray pushing assembly 810, which includes a tray connecting block 820, a pushing cylinder 830, a tray slider 840, and a tray slide rail 850. The pushing cylinder 830 is connected to one side of the take-up tray 800, the tray connecting block 820 is connected to the bottom of the take-up tray 800, and the tray slider 840 is connected to the bottom of the tray connecting block 820. The tray slider 840 is slidably connected to the tray slide rail 850 on the frame 100 to move the full needle boxes on the take-up tray 800 to the pickup area 180. Specifically, the front needle box transfer module 600, according to a program, sequentially places multiple full needle boxes filled with drill bits onto different output positions 160 of the take-up tray 800. The tray is moved to the preset pick-up area 180, from which the operator can take the full needle box.

[0033] Furthermore, such as Figure 9 As shown, the frame 100 is also equipped with a return mechanism 900 for empty needle boxes, including an empty box feeding mechanism 920 and an empty box storage bin 910. The empty box feeding mechanism 920 includes a conveyor motor 930, a conveyor belt 940 and a conveyor mounting plate 950. The conveyor mounting plate 950, which is mounted on the frame 100, is connected to the conveyor motor 930 on one side. The conveyor motor 930 drives the conveyor belt 940 located on the conveyor mounting plate 950 to rotate. One end of the conveyor belt 940 is located in the pickup area 180, and the other end extends to the bottom of the front needle box transfer module 600. The empty box storage bin 910 is located on one side of the conveyor belt 940. The empty box storage bin 910 stores multiple vertically arranged empty needle boxes. The bottom of the empty box storage bin 910 is equipped with a movable top extension plate 911 to extend the empty needle boxes one by one.

[0034] Specifically, the spare tray 720 requires an empty needle box to load drill bits, therefore, empty needle boxes need to be added or reused. This design has three main methods for empty box return: 1. After the operator takes the full needle box from the pick-up area 180, the empty needle box is placed back at the pick-up area 180 end of the conveyor belt 940. The conveyor belt 940 starts and transports the empty needle box towards the forward-to-be-matched moving module 700. After reaching the approach position, the empty box is taken off by the front needle box transfer module 600 and placed on the spare tray 720 of the front-to-be-matched moving module 700.

[0035] 2. When more empty needle boxes are needed or for initial startup: The top extension plate 911 at the bottom of the empty box storage compartment 910 is activated, pushing the bottommost empty needle box onto the frame 100. The front needle box transfer module 600 can then pick up the empty needle box and place it on the conveyor belt 940. Repeat the above steps 1. The conveyor belt 940 is activated, transporting the empty needle box towards the front ready-to-be-fit moving module 700. Once it reaches the nearest position, the empty needle box is removed by the front needle box transfer module 600 and placed on the spare tray 720 of the front ready-to-be-fit moving module 700.

[0036] 3. When the raw material needle box on the rear needle box to be matched is empty after the drill bit is removed, it becomes an empty needle box. The rear needle box transfer module 300 moves the empty needle box to the output end of the tool magazine conveying mechanism 200. The output end extends to one side of the front needle box to be matched. The empty needle box is removed by the front needle box transfer module 600 and placed on the spare plate 720 of the front needle box to be matched.

[0037] Furthermore, such as Figure 9 As shown, the frame 100 is equipped with multiple barcode readers 170 for detection and positioning. The barcode readers 170 are located at the front and rear ends of the tool magazine conveying mechanism 200 and the empty box feeding mechanism 920, and work with the blocking device to limit the movement of the empty needle box.

[0038] Furthermore, such as Figure 10As shown, the tool magazine 1000 includes a vertical magazine frame 1020 and a material handling unit. The tool magazine 1000 is provided with an inlet 1010 and an outlet 1011.
