Description

Technical Field

[0001] This utility model relates to the technical field of printed circuit board processing equipment, specifically to an automatic circuit board feeding device. Background Technology

[0002] PCB (Printed Circuit Board), 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 connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. The rapid development of my country's information electronics industry has provided a favorable market environment for the rapid development of the PCB industry. The continuous growth in the production of electronic communication equipment, computers, and home appliances has provided strong impetus for the rapid growth of the PCB industry. With the development of the electronics industry, the demand for high-end products such as precision circuit boards, thick backplanes, and high-end HDI boards is increasing. The manufacturing technology for these products is complex, with many technical challenges and intricate process control methods. The fabrication of the outer layer circuitry is one of the more critical technical difficulties. The outer layer circuitry is typically obtained through the following process: electroplating → resin via plugging → board grinding → copper thinning → outer layer circuitry. Before the electroplating process, pre-treatment processes such as board grinding are required, and a board feeding device is used to transport the circuit board to the grinding device.

[0003] In existing technologies, during the conveying of circuit boards by the board feeding device, thinner circuit boards are prone to deformation due to insufficient rigidity, making it difficult for them to pass smoothly through the rollers. When a malfunction occurs, the board feeding device is usually stopped manually to troubleshoot the problem. If the malfunction is not detected in time, it will cause a delay in the board feeding device's shutdown, affecting work efficiency.

[0004] Therefore, the purpose of this utility model is to provide a new plate-inserting device structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic circuit board feeding device that can automatically stop the machine and issue an alarm to notify the operator to troubleshoot the fault when a fault occurs, thus ensuring safe production and work efficiency.

[0006] The technical solution of this utility model is as follows:

[0007] An automatic circuit board feeding device includes a frame, a conveying device disposed on the frame, an electronic sensor disposed on the frame for detecting the transmission parameters of the circuit boards on the conveying device, a start / stop switch for controlling the start and stop of the conveying device, an alarm and a controller, wherein the electronic sensor is electrically connected to the controller, and the controller is electrically connected to the start / stop switch and the alarm.

[0008] Furthermore, the electronic sensor is a proximity switch located near the end of the conveying device.

[0009] Furthermore, the controller is a PLC controller.

[0010] Furthermore, it also includes a plate thickness measuring device, which is electrically connected to the controller.

[0011] Furthermore, the plate thickness measuring device is one of an ultrasonic measuring device, a laser measuring device, or an electromagnetic wave measuring device.

[0012] Compared with the prior art, the automatic circuit board feeding device provided by this utility model has the following advantages:

[0013] I. The automatic circuit board feeding device provided by this utility model uses an electronic sensor to detect the transmission parameters of the circuit boards on the conveying device to determine whether the circuit boards are being transported normally. When an abnormality is detected in the circuit board transmission, the controller sends a command to the start / stop switch to stop the conveying device. At the same time, the abnormal circuit board transmission signal is sent to the alarm, which sounds an alarm to remind the staff of the abnormal operation. This allows for timely troubleshooting, ensures normal production, and improves work efficiency.

[0014] II. The automatic circuit board feeding device provided by this utility model automatically detects the thickness information of the circuit board by setting a board thickness measuring device, which is used to automatically adjust the parameters of the subsequent grinding brush roller, thereby further improving the automation level of the electroplating pretreatment process.

[0018] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, and to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be further described below in conjunction with the accompanying drawings.

[0019] It should be noted that the descriptions of these embodiments are for the purpose of aiding understanding of the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Please refer to the following: Figure 1 and Figure 2 ,in Figure 1 This is a structural schematic diagram of the automatic circuit board feeding device of this utility model. Figure 2 This is a block diagram illustrating the control principle of the automatic circuit board feeding device of this utility model. The automatic circuit board feeding device of this utility model includes a frame 1, a conveying device 2 mounted on the frame 1, an electronic sensor 3 mounted on the frame 1, a start / stop switch 4, an alarm 5, and a controller 6. The electronic sensor 3 is electrically connected to the controller 6, and the controller 6 is electrically connected to the start / stop switch 4 and the alarm 5.

[0021] Electronic sensor 3 is used to detect the transmission parameters of the circuit board on the conveying device, including whether a circuit board is passing by, the conveying speed, and the conveying frequency, and sends the detection information to controller 6. In this embodiment, electronic sensor 3 is a proximity switch, installed near the end of the conveying device. When a circuit board approaches the proximity switch, it changes the inductance in the proximity switch sensor, thereby generating a changing electrical signal. By detecting the frequency of this electrical signal, the conveying frequency and speed of the circuit board can be detected. When the proximity switch detects that the conveying frequency and speed of the circuit board are not within the set range, it can be determined that there is no board being conveyed or the board is stuck, indicating an abnormality in the circuit board conveying.

[0022] Electronic sensor 3 sends a detection signal to the controller. The controller compares the detection signal with preset parameter values. When the circuit board conveying is abnormal, it sends control commands to the start / stop switch and alarm, controlling the conveying device to stop working and triggering the alarm to prompt personnel to check and troubleshoot the fault. In this embodiment, controller 6 is a PLC controller, which can realize the setting of working parameters and other needs.

[0023] In this invention, preferably, a board thickness measuring device 7 is provided in the board feeding section to detect the thickness of the circuit board being transported in real time. The board thickness measuring device 7 is electrically connected to the controller 6 and sends the detection signal to the controller. By setting up the board thickness measuring device, the board thickness information of the circuit board is automatically detected, which can be used by the controller to automatically adjust the parameters of the subsequent grinding brush roller, further improving the automation level of the electroplating pretreatment process. Specifically, the board thickness measuring device is one of an ultrasonic measuring device, a laser measuring device, or an electromagnetic wave measuring device.

[0024] The automatic circuit board feeding device provided by this utility model uses electronic sensors to detect the transmission parameters of circuit boards on the conveying device to determine whether the circuit boards are being transported normally. When an abnormality is detected in the circuit board transmission, the controller sends a command to the start / stop switch to stop the conveying device. At the same time, the abnormal circuit board transmission signal is sent to the alarm, which sounds an alarm to remind the staff of the abnormal operation. This allows for timely troubleshooting, ensures normal production, and improves work efficiency.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
