Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] In the PCB (Printed Circuit Board) manufacturing process, mechanical drilling is involved. Generally, in a PCB production workshop, drill bits, milling cutters, and other similar products are stored in standard material boxes. Before the drilling equipment starts operating, it is necessary to perform pin matching and / or drill bit sorting. Pin matching refers to the process of distributing drill bits of various specifications from different material boxes into the same material box. Drill bit sorting refers to removing a certain number of drill bits from a material box that is full of single-specification drill bits, so that the number of drill bits in that material box exactly meets the usage requirements.

[0036] In related technologies, the equipment used for sorting drill bits is inefficient, which affects the processing efficiency of the products.

[0037] Based on this, see Figure 1 and Figure 4This application provides an automatic drill bit sorting device, which includes a first material box conveying device 100, a material box buffer bracket 200, and a handling device 300.

[0038] The first material box conveying device 100 is used to drive the material box 500 back and forth between the first station R1 and the second station (not shown in the figure). The material box 500 is provided with multiple storage slots 510 for inserting drill bits 600. The material box buffer bracket 200 is located at the third station R2, and the material box buffer bracket 200 is provided with multiple buffer positions 210 for placing the material box 500.

[0039] The conveying device 300 includes a transfer mechanism 310, a first clamping mechanism 320, and a second clamping mechanism 330. The transfer mechanism 310 is used to drive the first clamping mechanism 320 and the second clamping mechanism 330 back and forth between the first station R1 and the third station R2. The first clamping mechanism 320 is used to pull out the drill bit 600 from the storage tank 510 or insert the drill bit 600 into the storage tank 510. The second clamping mechanism 330 is used to clamp or release the material box 500.

[0040] It should be noted that, in this application, the first material box conveying device 100 may be, but is not limited to, a continuous conveying device such as a belt conveyor or a chain conveyor, which can convey the material box 500 along a preset track and realize the function of driving the material box 500 back and forth between the first station R1 and the second station.

[0041] The first station R1 and the second station can be the end and beginning of the conveying process of the first material box conveying device 100, respectively. Alternatively, the first station R1 can be the middle of the conveying process of the first material box conveying device 100, and the second station can be any other area of ​​the automatic drill bit sorting equipment, such as the material box loading / unloading area. It should be noted that the first material box conveying device 100 has an automatic start / stop function, meaning it can continuously convey the material box and pause conveying of the material box 500, meeting the needs of other devices on site for picking up and placing the material box 500.

[0042] See Figure 3 In this application, the material box 500 refers to a box-shaped structure used to store the drill bit 600. The material box 500 can be a square, prism, or cylinder, and there is no specific limitation. The multiple storage slots 510 on the material box 500 can be arranged in a single row with intervals, or in an array, that is, in multiple rows and columns. The shape of the storage slots 510 is adapted to the shape of the drill bit 600. For example, if the drill bit 600 is a cylindrical rod-shaped drill bit or a square column-shaped drill bit, the storage slot 510 is a corresponding cylindrical slot or square column-shaped slot. It should be noted that the depth of the storage slot 510 is less than the length of the drill bit 600, so that after the drill bit 600 is inserted into the storage slot 510, the top of the drill bit 600 protrudes from the storage slot 510, which facilitates the first clamping mechanism 320 to pull out the drill bit 600 from the storage slot 510.

[0043] See Figure 2 In this application, the material box buffer bracket 200 refers to a bracket structure for holding multiple material boxes 500. It can be a frame structure such as a square, prism, or cylinder. The multiple buffer positions 210 on the material box buffer bracket 200 can be slotted structures whose shape is adapted to the shape of the material box 500. For example, if the material box 500 is a square box or a cylindrical box, the corresponding buffer position 210 is a square slot or a cylindrical slot. In addition, the third station R2 refers to the position of the material box buffer bracket 200, and also the position of each buffer position 210 on the material box buffer bracket 200.

[0044] See Figure 4 In the handling device 300 of this application, the transfer mechanism 310 may be, but is not limited to, a four-axis manipulator, a six-degree-of-freedom manipulator, etc. The output end of the transfer mechanism 310 is connected to the first clamping mechanism 320 and the second clamping mechanism 330, thereby driving the first clamping mechanism 320 and the second clamping mechanism 330 to move back and forth in space between the first workstation R1 and the third workstation R2.

[0045] The first clamping mechanism 320 can be configured as a cooperating structure of a moving drive and a clamping assembly. The driving end of the moving drive is connected to the clamping assembly to drive the clamping assembly to move towards the material box 500, so that the clamping assembly clamps the drill bit 600 in the storage slot 510 of the material box 500. Then, the clamping assembly is driven to move away from the material box 500 to complete the action of pulling out the drill bit 600 from the storage slot 510. Additionally, the moving drive drives the clamping assembly holding the drill bit 600 to move towards the material box 500, so that the clamping assembly inserts the drill bit 600 into the corresponding storage slot 510 and releases it, completing the action of inserting the drill bit 600 into the corresponding storage slot 510. The moving drive can be a linear cylinder, linear motor, etc., and the clamping assembly can be a gripper cylinder, pneumatic finger, etc. Similarly, the second clamping mechanism 330 can also be configured as a cooperating structure of a moving drive and a clamping assembly, which will not be described further here.

[0046] It should also be noted that in this application, there is no limitation on the number of the first material box conveying device 100, the material box buffer bracket 200 and the handling device 300, and there can be at least two of each, so as to improve the sorting efficiency of drill bits.

[0047] See Figure 1 Before the automatic drill bit sorting equipment of this application performs needle sorting (before drilling holes in the PCB board), the following preparatory actions are required:

[0048] After the first material box conveying device 100 transports the material boxes 500 to be sorted and the empty material boxes 500 to the first workstation R1, it determines whether there are material boxes 500 to be sorted on the material box buffer tray 200. If there are no material boxes 500 to be sorted on the material box buffer tray 200, it then determines whether there is an idle buffer space 210 on the material box buffer tray 200. If there is an idle buffer space 210 on the material box buffer tray 200, the transfer mechanism 310 of the conveying device 300 drives the second clamping mechanism 330 to move to the first workstation R1, so that the second clamping mechanism 330 clamps the empty material box 500 at the first workstation R1. The transfer mechanism 310 then drives the second clamping mechanism 330 to move to the third station R2, causing the second clamping mechanism 330 to release the empty material box 500 on it and place it into the corresponding buffer position 210 of the material box buffer tray 200. If there is no free buffer position 210 on the material box buffer tray 200, the transfer mechanism 310 of the conveying device 300 needs to cooperate with the second clamping mechanism 330 to remove the material box 500 from one of the buffer positions 210 on the material box buffer tray 200, so that there is a free buffer position 210 on the material box buffer tray 200, which is used to place the empty material box 500. In the above process, if there is a material box 500 to be sorted on the material box buffer tray 200, the above action of moving the empty material box 500 to the corresponding buffer position 210 of the material box buffer tray 200 is not required.

[0049] After the above preparatory actions are completed, the automatic drill bit sorting equipment begins to sort the drill bits. The operation process is as follows: The transfer mechanism 310 drives the first clamping mechanism 320 to move to the first station R1, so that the first clamping mechanism 320 pulls out the drill bit 600 from the material box 500 to be sorted at the first station R1. The transfer mechanism 310 then drives the first clamping mechanism 320 to move to the third station R2, so that the first clamping mechanism 320 inserts the drill bit 600 on it into the material box 500 to be sorted at the third station R2 (this material box 500 can also be...). The transfer mechanism 310 moves the first clamping mechanism 320 to the third station R2, so that the first clamping mechanism 320 pulls out the drill bit 600 in the material box 500 to be sorted located at the third station R2. The transfer mechanism 310 then moves the first clamping mechanism 320 to the first station R1, so that the first clamping mechanism 320 inserts the drill bit 600 on it into the corresponding storage slot 510 in the material box 500 to be sorted located at the first station R1. The transfer mechanism 310 drives the first clamping mechanism 320 to continuously move back and forth between the first station R1 and the third station R2, ensuring that the number of drill bits 600 in the sorting boxes 500 at the first station R1 and the number of drill bits 600 in the sorting boxes 500 at the third station R2 meet the production requirements, thus completing the sorting of the drill bits 600 in the sorting boxes 500 at the first station R1 and the third station R2. Then, the transfer mechanism 310 drives the second clamping mechanism 330 to move to the third station R2, where the second clamping mechanism 330 picks up the sorted boxes 500 at the third station R2. The transfer mechanism 310 then drives the second clamping mechanism 330 to move to the first station R1, where the second clamping mechanism 330 releases the sorted boxes 500 and places them in the first station R1. Finally, the first material box conveying device 100 transports all the sorted material boxes 500 at the first station R1 to the second station. In this way, the needle sorting operation of the drill bits 600 in the material boxes 500 is completed.

[0050] Furthermore, the automatic drill bit sorting equipment of this application embodiment can also perform return needle sorting (after drilling holes in the PCB board). Before performing return needle sorting, the same preparatory actions as the aforementioned needle matching sorting are required. After the preparatory actions are completed, the automatic drill bit sorting equipment begins to perform return needle sorting. The operation flow is as follows:

[0051] The transfer mechanism 310 drives the first clamping mechanism 320 to move to the first station R1, causing the first clamping mechanism 320 to pull out the drill bit 600 from the material box 500 to be sorted at the first station R1. The transfer mechanism 310 then drives the first clamping mechanism 320 to move to the third station R2, causing the first clamping mechanism 320 to insert the drill bit 600 on it into the corresponding storage slot 510 of the material box 500 to be sorted at the third station R2 (this material box 500 can also be the empty material box 500 that was transported in earlier). This process is repeated until the material box 500 to be sorted at the third station R2 is fully loaded with drill bits. The first station 600 completes the needle return sorting; or, the transfer mechanism 310 drives the first clamping mechanism 320 to move to the third station R2, so that the first clamping mechanism 320 pulls out the drill bits 600 from the material box 500 to be sorted at the third station R2. The transfer mechanism 310 then drives the first clamping mechanism 320 to move to the first station R1, so that the first clamping mechanism 320 inserts the drill bits 600 on it into the corresponding storage slot 510 in the material box 500 to be sorted at the first station R1. This process is repeated until the material box 500 to be sorted at the first station R1 is full of drill bits 600, completing the needle return sorting. Finally, the first material box conveying device 100 transports all the material boxes 500 full of drill bits 600 at the first station R1 to the second station. In this way, the needle return sorting action of the drill bits 600 in the material box 500 is completed.

[0052] It is not difficult to understand that the automatic drill bit sorting equipment in this embodiment of the application is configured through the cooperation of the first material box conveying device 100, the material box buffer bracket 200, and the transfer mechanism 310, the first clamping mechanism 320, and the second clamping mechanism 330 on the handling device 300. The transfer mechanism 310, in cooperation with the first clamping mechanism 320, pulls out the drill bit 600 from the material box 500 at the first station R1 and transfers it to the material box 500 at the third station R2, or transfers the drill bit 600 from the material box 500 at the third station R2 to the material box 500 at the third station R2. The drill bits 600 in the material box 500 are pulled out and transferred to the material box 500 at the first station R1, so that the drill bits 600 in the corresponding material box 500 meet the production and processing quantity requirements. At the same time, the transfer mechanism 310, together with the second clamping mechanism 330, moves different material boxes 500 back and forth between the first station R1 and the third station R2, so that the corresponding material boxes 500 can be loaded or unloaded smoothly. In this way, efficient automatic needle matching and sorting of drill bits and return needle sorting are achieved, thereby improving the processing efficiency of products.

[0053] See also Figure 1 In some embodiments of this application, the first material box conveying device 100, the material box buffer bracket 200, and the handling device 300 each have at least two.

[0054] Each first material box conveying device 100, each material box buffer bracket 200 and each handling device 300 constitute a sorting group, with a total of two sorting groups. The automatic drill bit sorting equipment may also include a frame 700, with the two sorting groups symmetrically arranged on the frame 700.

[0055] With the above settings, there are at least two sorting groups, at least one of which performs automatic needle matching and sorting, and at least one of which performs automatic needle return sorting, thereby improving the sorting efficiency of drill bits 600 and further improving the processing efficiency of the product.

[0056] See also Figure 1 In some embodiments of this application, the automatic drill bit sorting equipment also includes a second material box conveying device 400, which is used to drive the material box 500 back and forth between the fourth station R3 and the fifth station (not shown in the figure). The transfer mechanism 310 can also drive the second clamping mechanism 330 back and forth between the third station R2 and the fourth station R3.

[0057] Specifically, the second material box conveying device 400 may be, but is not limited to, a continuous conveying device such as a belt conveyor or a chain conveyor, which can convey the material box 500 along a preset track and realize the function of driving the material box 500 back and forth between the fourth station R3 and the fifth station.

[0058] The fourth station R3 and the fifth station can be the end and start of the conveying process of the second material box conveying device 400, respectively. Of course, the fourth station R3 can also be the middle end of the conveying process of the second material box conveying device 400. The fifth station is other areas of the automatic drill bit sorting equipment, such as the material box loading and unloading area. The second material box conveying device 400 has an automatic start and stop function, that is, the function of continuously conveying the material box and pausing the conveying of the material box 500, to meet the picking and placing needs of other devices on site for the material box 500.

[0059] To simplify the overall structure and design cost of the automatic drill bit sorting equipment, in this embodiment, both the first material box conveying device 100 and the second material box conveying device 400 are belt conveyors. There are two of each of the first material box conveying device 100, the material box buffer bracket 200 and the handling device 300, forming two sorting groups. There is one second material box conveying device 400. The two sorting groups are distributed at intervals relative to the second material box conveying device 400.

[0060] Referring to the foregoing, before performing needle sorting and needle return sorting, the automatic drill bit sorting equipment needs to determine whether there is an idle buffer position 210 on the material box buffer tray 200. If there is an idle buffer position 210 on the material box buffer tray 200, the transfer mechanism 310, in conjunction with the second clamping mechanism 330, moves the empty material box 500 to the idle buffer position 210. If there is no idle buffer position 210 on the material box buffer tray 200, the transfer mechanism 310, in conjunction with the second clamping mechanism 330, needs to remove the material box 500 from one of the buffer positions 210 on the material box buffer tray 200, so that there is an idle buffer position 210 on the material box buffer tray 200, which is used to place the empty material box 500.

[0061] Based on this, this application adds a second material box conveying device 400, which can be specifically used to transport empty material boxes 500 and material boxes 500 moved from the fully loaded material box buffer tray 200. In this way, there are multiple material box conveying devices at different locations conveying the corresponding types of material boxes 500, working in coordination with the handling device 300 to further improve the sorting efficiency of the drill bit 600 and correspondingly improve the processing efficiency of the product.

[0062] In some embodiments of this application, see Figure 5 The conveying device 300 also includes a mounting frame 340, a first clamping mechanism 320 and a second clamping mechanism 330 are both mounted on the mounting frame 340, and the output end of the transfer mechanism 310 is connected to the mounting frame 340 to drive the mounting frame 340 to move in space.

[0063] Specifically, the mounting frame 340 is a structural component that supports the first clamping mechanism 320 and the second clamping mechanism 330. The mounting frame 340 may be, but is not limited to, a plate structure or a frame structure, and its material may be steel, cast iron, welded frame, etc.

[0064] By integrating the first clamping mechanism 320 and the second clamping mechanism 330 on the mounting frame 340, the conveying device 300 can not only move the transfer box 500 or the drill bit 600 separately, but also move the transfer box 500 and the drill bit 600 at the same time. Moreover, it can save the overall structural space occupied by the conveying device 300 and reduce the control difficulty of the conveying device 300.

[0065] Further, see Figure 5The first clamping mechanism 320 has multiple first clamping mechanisms 320 arranged along the first direction X on the mounting frame 340. The first clamping mechanism 320 includes a first driving member 321 and a first clamping assembly 322 connected to the driving end of the first driving member 321. The first driving member 321 is used to drive the first clamping assembly 322 to move along a third direction Z intersecting the first direction X. The first clamping assembly 322 is used to clamp or release the drill bit 600.

[0066] The second clamping mechanism 330 has at least one component. The second clamping mechanism 330 includes a second driving member 331 and a second clamping assembly 332 connected to the driving end of the second driving member 331. The second driving member 331 is used to drive the second clamping assembly 332 to move along the second direction Y. The second clamping assembly 332 is used to clamp or release the material box 500. The second direction Y intersects or is parallel to the third direction Z.

[0067] The first direction X can be the length direction of the mounting bracket 340, and the third direction Z can be the width direction of the mounting bracket 340. Correspondingly, the second direction Y is the thickness direction of the mounting bracket 340. In this case, the second direction Y intersects perpendicularly with the third direction Z, or the second direction Y and the third direction Z are both the width direction of the mounting bracket 340 and are parallel. Of course, the first direction X can also correspond to the arrangement direction of the storage slots 510 on the material box 500. Each first clamping mechanism 320 corresponds to one storage slot 510 on the material box 500. In this way, the conveying device 300 can move and transfer multiple drill bits 600 on the material boxes 500 at one time.

[0068] In the first clamping mechanism 320 of this application, the first driving member 321 can be, but is not limited to, a single linear drive mechanism such as a cylinder, hydraulic cylinder, or linear motor, or a composite linear mechanism such as a lead screw mechanism, rack and pinion mechanism, linkage mechanism, cam mechanism, or screw lifting mechanism. For example, the first driving member 321 is a linear cylinder mounted on the mounting bracket 340, saving structural costs and reducing its space occupation. The first clamping assembly 322 can be, but is not limited to, a pneumatic gripper, hydraulic clamp, permanent magnet clamp, or elastic clamp. For example, the first clamping assembly 322 is a pneumatic gripper, saving structural costs and reducing its space occupation.

[0069] It is easy to understand that the depth direction of the storage slot 510 on the material box 500 corresponds to the third direction Z. The first driving member 321 can drive the first clamping assembly 322 to move along the third direction Z to the corresponding storage slot 510 on the material box 500 of the first station R1, so that the first clamping assembly 322 clamps the drill bit 600 in the storage slot 510. The first driving member 321 then drives the first clamping assembly 322 to move away from the storage slot 510 along the third direction Z, so that the first clamping assembly 322 can smoothly pull out the drill bit 600. Then, the transfer mechanism 310 drives the mounting frame 340 to move to the third station R2. The first drive component 321 then drives the first clamping assembly 322 to move along the third direction Z to the corresponding storage slot 510 on the material box 500 of the third station R2, so that the first clamping assembly 322 releases the drill bit 600 on it and inserts the drill bit 600 into the storage slot 510. In this way, the transfer of the drill bit 600 is realized.

[0070] It is understandable that on the mounting frame 340, the actions of all the first clamping mechanisms 320 are independent and do not interfere with each other, and each first clamping mechanism 320 is responsible for transporting and transferring one drill bit 600.

[0071] Similarly, in the second clamping mechanism 330 of this application, the second driving member 331 can be, but is not limited to, a single linear drive mechanism such as a cylinder, hydraulic cylinder, or linear motor, or a composite linear mechanism such as a lead screw mechanism, rack and pinion mechanism, linkage mechanism, cam mechanism, or screw lifting mechanism. For example, the second driving member 331 is a linear motor mounted on the mounting bracket 340, saving structural costs and reducing its space occupation. The second clamping assembly 332 can be, but is not limited to, a pneumatic gripper, hydraulic clamp, permanent magnet clamp, or elastic clamp. For example, the second clamping assembly 332 is a pneumatic gripper, saving structural costs and reducing its space occupation.

[0072] It is easy to understand that the second driving component 331 can drive the second clamping assembly 332 to move along the second direction Y to the material box 500 at the first station R1, so that the second clamping assembly 332 clamps the material box 500. The second driving component 331 then drives the second clamping assembly 332 to move along the third direction Z away from the first station R1. Then, the transfer mechanism 310 drives the mounting frame 340 to move as a whole to the third station R2. The second driving component 331 then drives the second clamping assembly 332 to move along the third direction Z to the corresponding buffer position 210 on the material box buffer bracket 200 at the third station R2, so that the second clamping assembly 332 releases the material box 500 on it and places the material box 500 in the buffer position 210. In this way, the material box 500 is transported and transferred.

[0073] It should also be noted that when the second clamping component 332 clamps the material box 500, the first clamping component 322 can also clamp the drill bit 600 inside the material box 500 under the driving action of the corresponding first driving component 321. This not only meets the individual material feeding needs of the material box 500 or the drill bit 600 at the processing site, but also meets the collaborative material feeding needs of the material box 500 and the drill bit 600, thereby improving the processing efficiency of the product.

[0074] It should be noted that on the mounting frame 340, the first clamping mechanism 320 and the second clamping mechanism 330 are arranged at intervals, such as the first clamping mechanism 320 and the second clamping mechanism 330 being arranged on different surfaces on the mounting frame 340, to avoid interference between the actions of the first clamping mechanism 320 and the second clamping mechanism 330.

[0075] It is easy to understand that by setting the conveying device 300 to the above structure, that is, by integrating multiple first clamping mechanisms 320 for conveying and transferring drill bits 600 and at least one second clamping mechanism 330 for conveying and transferring material boxes 500 on the mounting frame 340, it can individually clamp the drill bits 600 in the material box 500 and can also independently move and transfer the material box 500, saving the overall structural space occupied by the conveying device 300 and reducing the control difficulty of the conveying device 300. At the same time, through the synchronous operation of multiple first clamping mechanisms 320, multiple drill bits 600 continuously or discontinuously distributed in a row in the material box 500 can be conveyed and transferred at one time, improving the coordination of operations. Moreover, each first clamping mechanism 320 operates independently, correspondingly improving the flexibility of conveying and transferring drill bits 600 at different positions in the material box 500. The first clamping mechanism 320 and the second clamping mechanism 330 on the mounting frame 340 can also work together to meet the on-site requirements for the coordinated material supply of the material box 500 and the drill bits 600, thereby improving the processing efficiency of the product.

[0076] See Figure 1 and Figure 6 In some embodiments of this application, the first material box conveying device 100 includes a first conveying rail 110 and a first positioning member 120 disposed on the first conveying rail 110. The first conveying rail 110 is used to drive the material box 500 to move back and forth between the first station R1 and the second station. The first positioning member 120 is used to fix or release the material box 500 at the first station R1.

[0077] Specifically, the first conveyor rail 110 can be a belt conveyor rail, a sprocket conveyor rail, etc., and the first positioning element 120 can be a magnetic latch, an electric locking pin, etc., set on the first conveyor rail 110, so as to realize the function of fixing or releasing the material box 500 at the first work station R1.

[0078] It should be noted that by fixing the material box 500 at the first station R1 by the first positioning member 120, it is convenient for the transfer mechanism 310 to cooperate with the first clamping mechanism 320 to stably transport and transfer the drill bit 600 in the material box 500 or to transport and transfer the drill bit 600 in other material boxes 500 to the material box 500 at the first station R1. When it is necessary to continue to transport the material box 500 at the first station R1, the first positioning member 120 releases the material box 500 so that the material box 500 can be freely transported or transferred.

[0079] In some embodiments of this application, a barcode scanning mechanism 800 is provided at the position of the first conveyor rail 110 corresponding to the first workstation R1. The barcode scanning mechanism 800 is used to scan the material code of the material box 500. The material code includes the specification information and quantity information of the drill bit 600 stored in the material box 500.

[0080] The scanning device 800 can be, but is not limited to, an RFID scanner, a barcode scanner, a visual barcode reader, etc., and the material code can be a QR code, barcode, etc., affixed to the outer wall of the material box 500.

[0081] When the first conveyor rail 110 transports the material box 500 to the first workstation R1, the scanning mechanism 800 scans the material code of the material box 500. Based on the control logic of the background controller, it calculates and determines whether the material box 500 will be fixed to the first workstation R1 by the first positioning member 120 or transported by the handling device 300 to the corresponding buffer position 210 on the material box buffer tray 200. This improves the automation level of the drill bit automatic sorting equipment and further enhances the processing efficiency of the products.

[0082] In addition, in this embodiment of the application, the loading end and / or unloading end of the second material box conveying device 400 are also provided with corresponding scanning mechanisms. The scanning mechanism is used to scan the empty material box 500 and the material box 500 moved out from the fully loaded material box buffer tray 200 to obtain the material information of the corresponding material box 500, so that the background controller can control the operation of each device and further improve the product processing efficiency.

[0083] In some embodiments of this application, the automatic drill bit sorting equipment also includes a detection device (not shown in the figure) for detecting the number of drill bits 600 on the handling device 300.

[0084] The detection device can be a vision inspection system such as an industrial camera. The transfer mechanism 310 moves all the first clamping mechanisms 320 to the detection end of the detection device. The detection device detects whether all the first clamping mechanisms 320 are holding the drill bit 600, and determines the number of all the drill bits 600 on the conveying device 300. This determines whether the conveying device 300 has successfully conveyed the required number of drill bits 600. In this way, the automation level of the drill bit automatic sorting equipment can be improved, and the processing efficiency of the product can be further improved.

[0085] In addition, this application also provides a PCB drilling system, which includes the automatic drill bit sorting device of any of the above embodiments.

[0086] It should be understood that PCB drilling systems are used to drill holes in PCB boards.

[0087] In the PCB drilling system of this application embodiment, the PCB drilling system also includes drill bit storage devices such as vertical storage and buffer storage. All the first material box conveying devices 100 and the second material box conveying devices 400 of the automatic drill bit sorting equipment are arranged in the drill bit storage device and connected to the material output end of the drill bit storage device, thereby accelerating the sorting efficiency of drill bits, thereby improving the drilling efficiency of PCB and improving the processing efficiency of PCB.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
