Description

Technical Field

[0001] The utility model relates to the technical field of PCB drill bit production, in particular to an intelligent production line for grinding the slotting blade surface of a PCB drill bit. Background Art

[0002] A PCB drill bit is a tool used to drill holes in printed circuit boards (PCBs). It's typically made of high-hardness tungsten steel. During PCB manufacturing, the drill bit is mounted on a drilling machine and drills the PCB according to the designed hole location and size. Drill bits come in a variety of shapes and sizes. Choosing the right drill bit for your specific drilling requirements can improve both accuracy and efficiency.

[0003] The manufacturing of PCB drill bits requires multiple steps, including cutting, grinding, and polishing. After further grinding to form a finished, finished PCB drill bit, it needs to be transported to multiple stations for further processing to form the finished blade surface. Manual operation alone is prone to errors, so improvements are necessary. Utility Model Content

[0050] The present invention is described in detail below with reference to the accompanying drawings.

[0051] like Figures 1 to 9 As shown, the utility model is an intelligent production line for grinding the blade surface of a PCB drill bit slotting tool, including a central controller 1, multiple material trays 2, an AGV composite robot 3, a four-station slotting machine 4, a vertical warehouse for fine-grinded finished products 5, and a slotting composite sampling inspection robot 6. The central controller 1 is communicatively connected with the AGV composite robot 3, the four-station slotting machine 4, the vertical warehouse for fine-grinded finished products 5, and the slotting composite sampling inspection robot 6, respectively, so that the central controller 1 controls the AGV composite robot 3, the four-station slotting machine 4, the vertical warehouse for fine-grinded finished products 5, and the slotting composite sampling inspection robot 6, and feeds back processing information of the fine-grinded finished products to the central controller 1 through an identification mechanism.

[0052] The central controller 1 is the central control system MES manufacturing execution system, which has the functions of inventory management, location management, production task planning, automatic production scheduling according to order delivery date and equipment production status, production scheduling, real-time capture and storage of equipment status data and equipment production data, analysis and calculation, and generation of database functions of various data reports.

[0053] The material tray 2, the four-station slotting machine 4, the vertical warehouse for fine-grinding finished products 5, and the slotting composite sampling inspection robot 6 are all provided with unique identifiers. The material tray 2 is used to carry the fine-grinding finished products to be processed and the finished blade grinding products. The AGV compound robot 3 and the slotting composite sampling inspection robot 6 are provided with an identification mechanism for identifying the unique identifier. The AGV compound robot 3 and the slotting composite sampling inspection robot 6 identify the unique identifiers of the material tray 2, the four-station slotting machine 4, the vertical warehouse for fine-grinding finished products 5, and the coarse and fine grinding composite sampling inspection robot 6 through the identification mechanism. The unique identifier can be a QR code and / or an RFID chip. The identification mechanism includes a visual recognition camera and / or an RFID sensor, which enables the identification mechanism to identify the unique identifiers of the material tray 2, the four-station slotting machine 4, the vertical warehouse for fine-grinding finished products 5, and the slotting composite sampling inspection robot 6.

[0054] By using an identification mechanism to uniquely identify the material tray 2, the four-station slotting machine 4, and the finished product storage 5, the AGV composite robot 3 accurately identifies the material tray 2 and transports it between the four-station slotting machine 4 and the finished product storage 5, preventing manual errors. Furthermore, the AGV composite robot 3, the four-station slotting machine 4, and the slotting composite sampling robot 6 provide real-time feedback on the finished product grinding process, making PCB drill bit grinding a digital, dynamic, and real-time process. This allows for unified control of PCB drill bit grinding accuracy, ensuring consistency and pass rate, and facilitating monitoring of PCB drill bit processing progress. The central controller 1 monitors equipment status and production data to determine whether equipment maintenance is required, ensuring timely maintenance.

[0055] When in use, the material tray 2 carries the finished fine-grinding products to be processed and is placed in the finished fine-grinding product warehouse 5. The central controller 1 issues a production instruction to the AGV compound robot 3 and the four-station slotting machine 4. The production instruction includes the unique identification of the material tray 2, the four-station slotting machine 4 and the finished fine-grinding product warehouse 5. The AGV compound robot 3 receives the instruction and moves to the finished fine-grinding product warehouse 5. The AGV compound robot 3 uses the identification mechanism to identify that the unique identification of the finished fine-grinding product warehouse 5 and the material tray 2 is consistent with the content of the production instruction, and then feeds back to the central controller 1 and takes away the finished fine-grinding product warehouse 5. The AGV compound robot 3 transports the tray 3 carrying the finely ground finished product to the four-station slotting machine 4. The AGV compound robot 3 again uses the identification mechanism to identify the unique identification of the four-station slotting machine 4 and then feeds back to the central controller 1. The tray 3 carrying the finely ground finished product is placed in the four-station slotting machine 4. The four-station slotting machine 4 performs slotting blade surface grinding on the finely ground finished product carried in the tray 2. The finished blade surface grinding product is placed in the tray 2, so that the finely ground product to be processed can be processed into a blade surface grinding product.

[0056] The four-station slotting machine 4 is provided with an inspection disk, which is used to carry the sampled knife surface grinding products. Specifically, after the four-station slotting machine 4 reaches the preset processing volume, the four-station slotting machine 4 places the four processed knife surface grinding products on the inspection disk to form the sampled knife surface grinding products. The central controller 1 issues a sampling inspection instruction to the slotting composite sampling inspection robot 6. The slotting composite sampling inspection robot 6 receives the sampling inspection instruction and moves to the four-station slotting machine 4. The slotting composite sampling inspection robot 6 uses the identification mechanism to identify the unique identification of the four-station slotting machine 4 and the content of the sampling inspection instruction. After the identification mechanism identifies that the unique identification of the four-station slotting machine 4 is consistent with the content of the sampling inspection instruction, it feeds back to the central controller 1 and grabs the inspection disk. The slotting composite sampling inspection robot 6 inspects the sampled knife surface grinding products in the inspection disk. After the inspection is completed, the slotting composite sampling inspection robot 6 feeds back the inspection data of the sampled knife surface grinding products to the central controller 1, so that the central controller 1 can make compensatory adjustments to the processing parameters of the four-station slotting machine 4 by comparing the inspection data with the standard value and calculating the compensation value.

[0057] The AGV complex robot 3 in this embodiment includes an AGV carriage 31, a collaborative robot 32, and a tray fixture 33. The collaborative robot 32 is fixed to the AGV carriage 31 and is driven by the AGV carriage 31. The tray fixture 33 is fixed to the collaborative robot 32, allowing the collaborative robot 32 to drive the tray fixture 33 to grasp the tray 2. A recognition mechanism is fixed to the collaborative robot 32, allowing the recognition mechanism to identify the tray 2 as the collaborative robot 32 approaches it. This facilitates real-time feedback from the recognition mechanism on the processing progress of the finely ground finished product carried on the tray 2.

[0058] The four-station slotting machine 4 of this embodiment includes a slotting processing table 41 , a rotating manipulator 411 , a loading and unloading workstation 412 , a groove cutting workstation 413 , a side cutter workstation 414 , and a knife surface grinding workstation 415 .

[0059] The slotting processing table 41 is respectively provided with a first fixing fixture 42, a second fixing fixture 43, a third fixing fixture 44 and a fourth fixing fixture 45 corresponding to the loading and unloading workstation 412, the grooving workstation 413, the edge cutter workstation 414 and the knife surface grinding workstation 415.

[0060] The rotary robot 411 is rotatably disposed on the slotting processing table 41 and stops directly above the first fixing jig 42 , the second fixing jig 43 , the third fixing jig 44 and the fourth fixing jig 45 .

[0061] During use, the material tray 2 is fixed to the slotting processing table 41. The loading and unloading workstation 412 clamps the finished product to be processed in the material tray 2 and transfers it to the first fixed fixture 42. The first fixed fixture 42 clamps the finished product, allowing the loading and unloading workstation 412 and the rotating manipulator 411 to clamp or release the finished product, thereby transferring the finished product between the loading and unloading workstation 412 and the rotating manipulator 411. The second fixed fixture 43 clamps the finished product, allowing the grooving workstation 413 to perform grooving and grinding on the finished product. The third fixed fixture 44 clamps the finished product, allowing the trimming and edge grinding workstation 414 to perform trimming and edge grinding on the finished product. The finished fine-ground product is clamped by the fourth fixed fixture 45 so that the blade surface grinding workstation 415 can grind the blade surface of the finished fine-ground product to form the finished blade surface grinding product. The finished blade surface grinding product is transported to the material tray 2 by the loading and unloading workstation 412 and the rotating manipulator 411, making the grinding process of the finished fine-ground product more stable and ensuring the grinding yield of the finished fine-ground product.

[0062] The inspection plate is set on one side of the material plate 2. When the four-station slotting machine 4 reaches the preset processing volume, the four finished blade surface grinding products carried on the material plate 2 are clamped by the loading and unloading workstation 412 and placed in the inspection plate, so that the finished blade surface grinding products are placed in the inspection plate to become the sampled blade surface grinding products.

[0063] The end of the rotating manipulator 411 of this embodiment is provided with a fixing hole 4111, and the first fixing fixture 42 includes a first lifting driver 421, a pin 422, a first clamping driver 423 and a clamp 424. The first lifting driver 421 is a pneumatic cylinder, an oil cylinder, an electric cylinder or a linear slide module, and the first clamping driver 423 is an air clamp or a finger cylinder.

[0064] The first lifting driver 421 drives the ejector pin 422 to rise or fall so that the ejector pin 422 is inserted into or withdrawn from the fixing hole 4111 , and the first clamping driver 423 drives the clamp 424 to open or merge so that the clamp 424 clamps or releases the finished product.

[0065] When in use, the rotating manipulator 411 stops just above the first fixed fixture 42, and the first lifting driver 421 drives the ejector pin 422 to rise, so that the ejector pin 422 is inserted into the fixing hole 4111, so that the rotating manipulator 411 is restricted and stops rotating; the loading and unloading workstation 412 transports the finely ground finished product to the clamp 424, and the first clamping driver 423 drives the clamp 424 to merge so that the clamp 424 clamps the finely ground product; after the rotating manipulator 411 clamps the finely ground product, the first clamping driver 423 drives the clamp 424 to open so that the clamp 424 releases the finely ground product, and at the same time, the first lifting driver 421 drives the ejector pin 422 to descend, so that the rotating manipulator 411 can rotate freely, making it easier for the rotating manipulator 411 to transport the finely ground product to the grooving workstation 413.

[0066] The second fixture 43 , the third fixture 44 and the fourth fixture 45 of this embodiment all include a fixed clamping platform 401 , a clamping block 402 and a second clamping driver 403 . The second clamping driver 403 is a pneumatic cylinder, an oil cylinder, an electric cylinder or a linear slide module.

[0067] The fixed clamping platform 401 is provided with a limiting groove 404, the clamping block 402 is hinged to the fixed clamping platform 401, the clamping block 402 is provided with a holding portion 405, and the two ends of the second clamping driver 403 are respectively hinged to the clamping block 402 and the fixed clamping platform 401. The second clamping driver 403 drives the clamping block 402 to approach the limiting groove 404, and the holding portion 405 presses the fine-ground product to be limited to the limiting groove 404, which facilitates the grooving workstation 413, the edge knife workstation 414 and the knife surface grinding workstation 415 to grind the fine-ground product.

[0068] The second fixed fixture 43 and the fourth fixed fixture 45 of this embodiment are both provided with a supporting platform 406 and a supporting bar 407 for supporting the finely ground product. The supporting platform 406 is arranged on one side of the fixed clamping platform 401 located at the limiting groove 404, and the supporting platform 406 is provided with a limiting slider 408. The supporting bar 407 is passed through the limiting slider 408. The surface of the supporting bar 407 is provided with a groove 409 for supporting the upper part of the finely ground product, which is convenient for grinding the finely ground product on the one hand, and on the other hand, the groove 409 can effectively protect the finely ground product to avoid excessive grinding.

[0069] The third fixing fixture 44 of this embodiment is provided with a first resisting member 441, a second resisting member 442, a rotating shaft connecting plate 443, a holding member 444 and a second lifting driver 445. The second lifting driver 445 is a pneumatic cylinder, an oil cylinder, an electric cylinder or a linear slide module.

[0070] The first and second resisting members 441 and 442 are collinearly arranged on one side of the fixed clamping platform 401 at the limiting groove 404 , so that when the finely ground product is placed in the limiting groove 404 , the finely ground product respectively resists the first and second resisting members 441 and 442 .

[0071] The shaft coupling plate 443 is rotatably connected to the fixed clamping platform 401 , the holding member 444 is arranged on the shaft coupling plate 443 and is arranged opposite to the second resistance member 442 , and the second lifting driver 445 drives the shaft coupling plate 443 to rotate so that the holding member 444 approaches or moves away from the second resistance member 442 .

[0072] When in use, the rotating manipulator 411 places the finely ground product in the limiting groove 404, and the finely ground product respectively contacts the first resistance member 441 and the second resistance member 442. The second lifting driver 445 drives the rotating shaft connecting plate 443 to rotate so that the pressing member 444 is close to the second resistance member 442, so that the pressing member 444 and the second resistance member 442 clamp the finely ground product, which is convenient for grinding the finely ground product.

[0073] The finished product storage 5 of this embodiment includes a storage frame 51, a first conveyor belt set 52 and a second conveyor belt set 53. The first conveyor belt set 52 and the second conveyor belt set 53 are stacked on the storage frame 51, and specifically, the second conveyor belt set 53 is arranged above the first conveyor belt set 52.

[0074] Both the first conveyor belt group 52 and the second conveyor belt group 53 are equipped with multiple conveyor belts 54, which are synchronous pulley conveyor belts. The conveyor belts 54 are equipped with a feed end 541 and a retrieving end 542. The material tray 2 carrying the finished product to be processed is placed on the conveyor belt 54 from the feed end 541. The conveyor belt 54 transports the material tray 2 from the feed end 541 to the retrieving end 542, allowing the AGV compound robot 3 to retrieve the material tray 2 from the retrieving end 542 of the finished product vertical warehouse 5.

[0075] The feeding end 541 is provided with an illumination lamp 543 , which is used to illuminate the material tray 2 carrying the finished product to be processed and finely ground, so as to facilitate placement of the material tray 2 on the feeding end 541 of the conveyor belt 54 .

[0076] The material pickup end 542 is provided with a material sensor 544. The central controller 1 is in communication with the conveyor belt 54, the lighting 543, and the material sensor 544, respectively, to facilitate the central controller 1 to control the operation of the conveyor belt 54, the lighting 543, and the material sensor 544. The material sensor 544 is a touch switch. When the material tray 2 at the material pickup end 542 is removed by the AGV compound robot 3, the material sensor 544 no longer senses the material tray 2.
