Description

Technical Field

[0001] The invention belongs to the technical field of drill needle sorting, and in particular relates to a fully automatic batching mechanism for a needle box. Background Art

[0002] PCBs, also known as printed circuit boards, are important electronic components that support and electrically connect electronic components. Because they are manufactured using electronic printing technology, they are called "printed" circuit boards. PCBs often require pre-recorded holes, with multiple holes reserved for mounting different components. This requires different hole diameters, necessitating the use of drill bits of varying specifications. To improve punching efficiency, existing techniques employ a series of tools of varying specifications, sequentially arranging them to punch holes simultaneously across the PCB, according to the area of ​​the board.

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

[0004] The above solution utilizes a multi-stage transmission module, including a lifting and retrieval mechanism, a paddle transmission mechanism, and an alternating support mechanism. This requires multiple positioning transitions, from the tool magazine to the first and then second positioning platforms. The alternating support mechanism utilizes a double-module nested design, while the tool removal mechanism absorbs the tool and finally, the paddle is discharged. This solution presents a complex process, a high error rate due to the multiple nested modules, and is prone to mechanical interference at high speeds, resulting in low assembly efficiency.

[0044] In one embodiment of the present invention, Figure 1 and Figure 2As shown, a fully automatic needle box dispensing mechanism is provided, which includes a frame 100, a tool magazine conveying mechanism 200, a rear needle box transplanting module 300, a needle dispensing module 500, a front needle box transplanting module 600, and a material receiving tray 800. A tool magazine 1000 is provided on one side of the frame 100, and a plurality of raw needle boxes of different models arranged in a matrix are placed and positioned in the tool magazine 1000, and the raw needle boxes are provided with drill needles of the same model. The tool magazine conveying mechanism 200 is provided above the frame 100 and connected to the tool magazine 1000. The rear needle box transplanting module 300 is movably provided on the frame 100, and a rear waiting to be dispensing movable module 400 is provided on the lower side of the rear needle box transplanting module 300. The needle dispensing module 500 is provided on the frame 100 and is located on one side of the rear waiting to be dispensing movable module 400. The front needle box transfer module 600 is movably mounted on the frame 100. A front matching mobile module 700 is located to one side of the front needle box transfer module 600. The matching module 500 pairs drill needles from different stock needle boxes and places them into the same empty needle box on the front matching mobile module 700. A receiving tray 800 is located to one side of the front matching mobile module 700. The front needle box transfer module 600 places a full needle box onto the receiving tray 800, which then moves the box to the pickup area 180.

[0045] Action flow:

[0046] The operator first transfers raw needle boxes to the tool magazine 1000 for storage via the tool magazine conveyor mechanism 200. Inside the tool magazine 1000, multiple raw needle boxes of different models are arranged in a matrix, each containing the same model of drill needles. When a specific model of raw needle box is needed, the tool magazine 1000 automatically transfers the corresponding box out of the tool magazine conveyor mechanism 200. The rear needle box transfer module 300 then moves the raw needle box to the rear assembly mobile module 400. The rear assembly mobile module 400 then drives the needle box to the appropriate position. The needle assembly module 500 then drives and grabs some of the drill needles from the different models of raw needle boxes on the rear assembly mobile module 400 and loads them into the empty needle boxes on the front assembly mobile module 700. After the loading is completed, the front waiting-to-be-assembled moving module 700 moves to the appropriate position, and the front needle box transplanting module 600 takes away the full needle box loaded with drill needles of different models and places it on the receiving tray 800, and then moves it from the receiving tray 800 to the picking area 180.

[0047] Further, if Figure 3As shown, the rear needle box transplanting module 300 includes a rear vertical bracket 310, a rear translation drive assembly 320, a rear lifting assembly 330 and a rear grabbing unit 340. The rear vertical bracket 310 is arranged on one side of the tool magazine 1000, the rear translation drive assembly 320 is arranged on the vertical bracket, the rear lifting assembly 330 is connected to the driving end of the rear translation drive assembly 320, and the rear grabbing unit 340 is connected to the driving end of the rear lifting assembly 330. There are several groups of rear-to-be-matched mobile modules 400, which are arranged in a matrix on the frame 100; the rear-to-be-matched mobile modules 400 include a rear driving cylinder 410, a needle disk 420, and a rear guide rod 430. There are two groups of rear guide rods 430, and both ends are connected to rear positioning pin seats 440. The rear driving cylinder 410 is sleeved on the two rear guide rods 430, and the driving end of the rear driving cylinder 410 is connected to any rear positioning pin seat 440. The needle disk 420 is installed above the rear-to-be-matched guide rod; the needle disk 420 moves to the end close to the tool magazine 1000 to form a loading position 120, and the end away from the tool magazine 1000 forms a waiting position 130.

[0048] Specifically, in the initial state or upon receiving a command, the rear drive cylinder 410 activates, pushing the needle tray 420 to the loading position 120 near the tool magazine 1000. The rear needle box transfer module 300 then places different raw needle boxes onto the corresponding needle tray 420. After loading is complete, the rear drive cylinder 410 activates, pulling and pushing the needle tray 420 along the guide rod to the waiting position 130 away from the tool magazine 1000. This solution simplifies and efficiently loads needle boxes, accelerating the subsequent needle matching process.

[0049] Further, if Figure 4 As shown, the needle matching module 500 includes needle matching brackets 510 symmetrically arranged on both sides of the frame 100. Each needle matching bracket 510 is provided with a movable needle matching horizontal push module 520 at the bottom, and the top is sequentially equipped with a first needle matching translation assembly 530, a second needle matching translation assembly 540, a needle matching lifting assembly 550, and a clamping assembly 560, wherein the driving end of the previous level assembly is connected to the next level assembly to form a motion transmission chain. Specifically, the first needle matching translation assembly 530, the second needle matching translation assembly 540, and the needle matching lifting assembly 550 are preferably motor linear drive modules. The first needle matching translation assembly 530 is for coarse adjustment, the second needle matching translation assembly 540 is for fine adjustment, and the needle matching lifting assembly 550 controls the lifting and lowering movement of the clamping assembly 560. There are multiple clamping assemblies 560, and the spacing between them is equal to the spacing between the spare trays 720. The clamping assembly 560 can be formed by the cooperation of a solenoid valve and a clamping claw. The needle matching module 500 places the drill needles on different raw needle boxes in the same empty needle box in sequence according to instructions.

[0050] Further, if Figure 5As shown, the front needle box transplanting module 600 includes a front vertical support 610, a front translation drive assembly 620, a front lifting assembly 630, and a front grabbing unit 640. The front vertical supports 610 are respectively arranged on both sides of the frame 100. The lower end of the front vertical supports 610 is provided with a movable front horizontal push module 650; the front vertical support 610 is provided with a front translation drive assembly 620, which is connected to the front lifting assembly 630, and the front grabbing unit 640 is connected to the driving end of the front lifting assembly 630. Specifically, the front translation drive assembly 620 and the front horizontal push module 650 are preferably motor linear drive modules, and the front lifting assembly 630 is preferably a cylinder drive module. The three cooperate to enable the needle box to move stably along three axes.

[0051] Further, if Figure 6 As shown, the front movable module 700 to be matched includes a front driving 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 is provided with several groups arranged in a matrix and fixedly connected to each other; the front guide rod 750 is provided with two groups, and both ends are connected with a front positioning pin seat 760. The front driving cylinder 710 is sleeved on the two front guide rods 750, and the driving end of the front driving cylinder 710 is connected to any front positioning pin seat 760; the front driving 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 matching position 140 on the side close to the needle matching module 500, and forms a full material position 150 on the side away from the needle matching module 500. Specifically, the front drive cylinder 710 operates, pushing the common spare tray 720 (carrying empty needle cassettes) 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 needles into the corresponding empty needle cassettes on the spare tray 720. When the current needle cassette is fully loaded with the required needles, the front drive cylinder 710 operates, pushing the spare tray 720 to move to the full position 150 away from the needle distribution module 500. The full needle cassette is then picked up by the front needle cassette transfer module 600 and moved to the material receiving tray 800. Specifically, two sets of front drive cylinders 710 are included here, each set of front drive cylinders 710 is equipped with six sets of spare trays 720, and six empty needle cassettes are distributed simultaneously.

[0052] Further, if Figure 7As shown, the front movable module 700 further includes a front pneumatic element 770. One side of the spare tray 720 is connected to the front pneumatic assembly, and the driving end of the front pneumatic element abuts the empty needle box. A front opening 780 is provided on the side of the spare tray 720 away from the front pneumatic assembly. A locking member 790 is also provided between the front movable module 700 and the rear movable module 400. The locking member 790's driving end extends into the corresponding front opening 780 to abut the empty needle box. Specifically, when the spare tray 720 moves to the needle-matching position 140, the driving end of the front pneumatic element 770 extends, pushing the empty needle box away from the front pneumatic element, abutting one side of the empty needle box. Simultaneously, the locking member 790's driving end extends, enters the spare tray 720 through the front opening 780, and abuts the other side of the empty needle box. These two elements work together to precisely position and clamp the empty needle box in the predetermined position on the spare tray 720.

[0053] Further, if Figure 8 As shown, a plurality of output positions 160 arranged in a matrix are located above the receiving tray 800. The front needle box transfer module 600 places full needle boxes at these output positions 160. Below the receiving tray 800, a tray push assembly 810 is located. This assembly includes a tray connection block 820, a push cylinder 830, a tray slider 840, and a tray rail 850. The push cylinder 830 is connected to one side of the receiving tray 800. The tray connection block 820 is connected to the bottom of the receiving tray 800. The tray slider 840 is connected below the tray connection block 820. The tray slider 840 slidably connects to the tray rail 850 on the frame 100 to move the full needle boxes on the receiving tray 800 to the pickup area 180. Specifically, the front needle box transfer module 600 sequentially places multiple full needle boxes filled with drill needles at different output positions 160 on the receiving tray 800 according to a program. The tray is moved to a pre-set pick-up area 180 from which the operator can remove the full needle magazine.

[0054] Further, if Figure 9 As shown, the frame 100 is also provided with a reflux 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 conveying motor 930, a conveyor belt 940 and a conveying mounting plate 950, the conveying mounting plate 950 is arranged on the frame 100, one side of which is connected to the conveying motor 930, and the conveying motor 930 drives the conveyor belt 940 located on the conveying mounting plate 950 to rotate; one end of the conveyor belt 940 is arranged in the picking area 180, and the other end extends to the bottom of the front needle box transplanting module 600; the empty box storage bin 910 is arranged on one side of the conveyor belt 940, and a plurality of vertically arranged empty needle boxes are stored in the empty box storage bin 910, and a movable top extension plate 911 is provided at the bottom of the empty box storage bin 910 to extend the empty needle boxes one by one.

[0055] Specifically, the spare tray 720 requires an empty needle box to load the drill needle, so the empty needle box needs to be added or reused. There are three main ways to return the empty box in this design:

[0056] 1. After the operator removes the full needle box from the pickup area 180, he or she places the empty needle box back to the pickup area 180 end of the conveyor belt 940. The conveyor belt 940 starts to move the empty needle box toward the front needle box transfer module 700. Once the empty box reaches the near position, the front needle box transfer module 600 removes it and places it on the spare tray 720 of the front needle box transfer module 700.

[0057] 2. When more empty needle boxes are needed or it is the first time to start: the top extension plate 911 at the bottom of the empty box storage bin 910 moves to push the lowest empty needle box onto the frame 100, and the front needle box transfer module 600 can clamp the empty needle box and place it on the conveyor belt 940, repeat the action in 1 above, the conveyor belt 940 starts, and transports the empty needle box toward the front waiting-to-match moving module 700. After reaching the close 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 waiting-to-match moving module 700.

[0058] 3. When the raw needle box on the rear movable module 400 is emptied of its drill needles and becomes an empty needle box, the rear needle box transferring module 300 moves the empty needle box to the output end of the tool magazine conveying mechanism 200, which extends to one side of the front movable module 700. The empty needle box is removed by the front needle box transferring module 600 and placed on the spare tray 720 of the front movable module 700.

[0059] Further, if Figure 9 As shown, the frame 100 is provided with a plurality of code readers 170 for detecting positioning.
