[0033] The PCB drilling device of the prior art ignores the problem of accurate positioning of the circuit board during the drilling process, and the defect of hole position deviation is easy to occur during the drilling process. Based on this, the present application provides a circuit board production device with accurate positioning. Example
[0034] like Figure 1-Figure 6 As shown, this embodiment provides a circuit board production device with precise positioning, including:
[0035] A machine body 1, wherein a conveying system 2 is disposed on the machine body 1, wherein a carrier 3 for carrying a circuit board is disposed on the conveying system 2, wherein a bearing position 321 is disposed on the carrier 3, and a limit block is disposed on one side of the bearing position 321, and wherein the conveying system 2 drives the carrier 3 to move on the machine body 1;
[0036] The body 1 is also provided with a drilling mechanism 4, which includes a drilling frame 41, a drill bit 42 and a drilling drive mechanism 43. The drilling frame 41 spans above the carrier frame 3, and the drill bit 42 and the drilling drive mechanism 43 are both provided on the drilling frame 41. The drilling drive mechanism 43 drives the drill bit 42 to move up and down on the drilling frame 41. The drilling drive mechanism 43 of the present application can be implemented by a three-axis drive mechanism, so that the drill bit 42 can be driven to move to different positions to drill holes in the circuit board. The drill bit 42 of the present application includes a tool and a motor that drives the tool to rotate.
[0037] An image acquisition device is provided at the bottom of the drilling frame 41 , and the image acquisition device is arranged on one side of the drill bit 42 .
[0038] The above-mentioned precise positioning circuit board production device can transport the circuit board to different positions through the movable carrier 3 so as to drill holes in different positions of the circuit board. A drilling mechanism 4 is also provided on the body 1 of the device, and the drilling mechanism 4 includes a drilling frame 41, a drill bit 42 and a drilling drive mechanism 43. The drilling frame 41 spans above the carrier 3, and the drill bit 42 and the drilling drive mechanism 43 are both arranged on the drilling frame 41. The drilling drive mechanism 43 drives the drill bit 42 to move up and down on the drilling frame 41. An image acquisition device is provided at the bottom of the drilling frame 41, and the image acquisition device is arranged on one side of the drill bit 42. During the drilling process, the device captures the image of the circuit board in real time through the image acquisition device at the bottom of the drilling frame 41, and cooperates with the drilling mechanism 4 for precise positioning, thereby realizing high-precision control of the drilling position of the circuit board. This drilling method improves the accuracy of drilling and ensures that each hole can be accurately placed at the predetermined position. High-precision drilling positioning not only reduces drilling deviation, but also helps to improve the overall production quality of circuit boards, improve product yield and output rate, and save production costs for enterprises.
[0039] Further, the image acquisition device is a CCD camera, 2-3 CCD cameras are arranged at the bottom of the drilling frame 41, and the CCD cameras are arranged in a ring shape at the edge of the drill bit 42;
[0040] The circuit board production device further includes a controller, and the CCD camera and the drilling drive mechanism 43 are both electrically connected to the controller.
[0041] The present application uses 2-3 CCD cameras arranged in a ring on the edge of the drill bit 42, so that the device can capture images of the circuit board from multiple angles at the same time, providing more comprehensive and accurate visual data, thereby further improving the positioning accuracy of the drilling position. Through the electrical connection between the controller and the CCD camera and the drilling drive mechanism 43, intelligent control of the drilling process is achieved. This control method can also quickly respond to the data provided by the image acquisition device, adjust the drilling position and depth in real time, and ensure the accuracy and consistency of the drilling.
[0042] Specifically, the positioning principle of the CCD camera is as follows: the CCD camera captures and measures the optical signal of the circuit board, and uses the steps of photoelectric conversion, charge storage and transfer, analog-to-digital conversion, signal processing and position determination to achieve accurate positioning of the position to be drilled. The controller determines the specific position of the position to be drilled on the circuit board based on the information fed back by the CCD camera. After the hole to be drilled moves to the target position, the controller drives the drilling drive mechanism 43 to make the drill bit 42 move downward, thereby drilling the circuit board. It should be noted that the control method of the electrical connection between the CCD camera and the controller in this application is the prior art.
[0043] In a specific embodiment, the support frame 3 includes a base frame 31 and a support plate 32. The base frame 31 is movably arranged on the body 1. Two opposite sides of the base frame 31 are provided with support legs 311. The support plate 32 is fixed on the two opposite support legs 311.
[0044] Two carrying plates 32 are provided, and the two carrying plates 32 are arranged in parallel and located in the same plane, and a carrying position 321 is formed between the two carrying plates 32. The design of two parallel carrying plates 32 not only provides a stable support surface, but also naturally forms a carrying position 321 between the two carrying plates 32, which can stably carry the circuit board. A debris tray 33 is provided on the base frame 31, and the debris tray 33 is located below the carrying position 321. The debris tray 33 is detachably arranged on the base frame 31, and can receive debris generated during the drilling process of the circuit board.
[0045] Furthermore, the carrier plate 32 is provided with a groove 322, and the bearing position 321 is formed between the grooves 322 on two carrier plates 32. The design of the groove 322 clarifies the placement position of the circuit board, and the groove 322 matches the shape and size of the circuit board, ensuring the precise positioning of the circuit board on the carrier plate 32, and providing an accurate reference for subsequent drilling operations.
[0046] The groove 322 design not only improves the positioning accuracy, but also enables the operator to place the circuit board in the correct position more quickly and easily, reducing the operating difficulty and placement time, thereby improving the overall work efficiency.
[0047] Further, a pressing block 35 is provided at the edge of the bearing position 321, and the pressing block 35 is connected to the bearing plate 32 through an elastic telescopic rod 34, and the elastic telescopic rod 34 is pivotally connected to the bearing plate 32. By arranging the pressing block 35 at the edge of the bearing position 321, the circuit board can be effectively fixed on the bearing position 321 to prevent the circuit board from moving or vibrating during the drilling process, thereby ensuring the accuracy of drilling and the quality of the circuit board. The pressing block 35 is connected to the bearing plate 32 through the elastic telescopic rod 34, and this design allows the pressing block 35 to be adaptively adjusted according to the thickness and shape of the circuit board. The elasticity of the elastic telescopic rod 34 ensures that the pressing block 35 can apply appropriate pressure to circuit boards of different thicknesses, thereby improving the reliability of fixation. Moreover, the pivotal design of the elastic telescopic rod 34 and the bearing plate 32 allows the pressing block 35 to flexibly adjust the angle within a certain range to adapt to circuit boards of different shapes and sizes. This flexibility not only facilitates the operator to quickly fix the circuit board, but also improves the versatility and adaptability of the equipment.
[0048] Furthermore, the conveying system 2 includes a guide rail 21 and a conveying drive system 22, the guide rail 21 is arranged on the top of the body 1, and the carrier 3 is slidably arranged on the guide rail 21;
[0049] The conveying drive system 22 includes a transmission rod 222 and a driving motor 221. Two mounting seats 11 are arranged on the top of the machine body 1. The transmission rod 222 is arranged on the two mounting seats 11, and the transmission rod 222 is rotatably matched with the mounting seats 11; one end of the transmission rod 222 passes through one of the mounting seats 11 and is provided with a first gear 223; the driving motor 221 is fixed on the machine body 1, and a second gear 224 is arranged at the output end of the driving motor 221, and a transmission belt is arranged between the first gear 223 and the second gear 224;
[0050] The length direction of the transmission rod 222 is the same as the length direction of the guide rail 21 . The transmission rod 222 is provided with a transmission block 225 . The transmission block 225 is threadedly connected to the transmission rod 222 . The side wall of the transmission block 225 is fixedly connected to the support frame 3 .
[0051] The working process of the conveying system 2 is as follows: the driving motor 221 drives the second gear 224 to rotate, so that the second gear 224 drives the first gear 223 to rotate through the transmission belt, thereby driving the transmission rod 222 to rotate. Since the transmission block 225 is threadedly connected to the transmission rod 222, and the transmission block 225 is fixedly connected to the carrier 3, the rotating transmission rod 222 can make the carrier 3 move linearly along the guide rail 21.
[0052] The transmission mode of the first gear 223, the second gear 224 and the transmission belt provides accurate rotation and conveying control. This design ensures the stable and accurate movement of the carrier 3 on the guide rail 21, providing a stable positioning basis for subsequent drilling operations.
[0053] Furthermore, a protective frame 12 is provided on one side of the drilling mechanism 4 , and the protective frame 12 surrounds the periphery of the drilling mechanism 4 , and the protective frame 12 is fixed on the machine body 1 .
[0054] By setting the protection frame 12 around the periphery of the drilling mechanism 4, the operator is effectively isolated from the drilling mechanism 4, preventing the operator from accidentally contacting the rotating drill bit 42 or other moving parts of the drilling mechanism 4 during the drilling process, thereby greatly reducing the operating risk and improving work safety. The protection frame 12 can not only protect the operator, but also play a certain protective role on the drilling mechanism 4. It can prevent external foreign matter from entering the interior of the drilling mechanism 4, avoid causing equipment damage or failure, and extend the service life of the equipment.
[0055] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
