[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said", and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless otherwise clearly indicated above, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0024] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] It should be understood that the terms "include", "comprises" or any other variations used herein are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0026] During the screen printing process of the circuit board (PCB), the thickness of the wet ink on the circuit and substrate of the PCB with a surface copper thickness greater than 3 ounces (OZ) will usually exceed 40um. The thicker ink will produce bubbles during stirring and screen printing. If the bubbles cannot be completely removed by standing for 15-30 minutes before pre-baking, the PCB board factory will use a machine to vacuum to eliminate the bubbles in the thick ink to avoid the ink falling off due to the residual solution of bubbles on the circuit or copper surface, which will cause short circuit / open circuit after the component is printed.

[0027] In the prior art, the PCB board is often manually moved into a vacuum box, and after the vacuum box is evacuated, the PCB board is manually moved into a tunnel oven, and after pre-baking, the PCB board is manually moved out.

[0028] However, the factory needs to process large batches of PCB boards every day. This method requires personnel to move the frames repeatedly, which greatly increases the labor intensity of employees and fails to effectively improve production efficiency.

[0029] Based on the above situation, the present application provides a circuit board automatic defoaming system, method, device and storage medium, which connects the vacuum machine and the tunnel oven in series through a connecting device, and replaces the manual frame moving with the feeding conveyor and the unloading conveyor, which can solve the problems of high labor intensity and low production efficiency caused by manual frame moving.

[0030] The present application is described in detail below with reference to the accompanying drawings and implementation methods.

[0031] See also Figure 1 , Figure 1 Schematic diagram of the structure of an embodiment of the automatic defoaming system for circuit boards of the present application. Figure 1 As shown, in this embodiment, the circuit board automatic defoaming system 100 includes an automated guided vehicle (AGV) 1, a feeding conveyor 2, a conveyor belt 3, a vacuum machine 4, a tunnel oven 5 and a unloading conveyor 6.

[0032] Among them, the vacuum machine 4 is located at one end of the tunnel oven 5; the feeding conveyor 2 is located at one end of the vacuum machine 4; the unloading conveyor 6 is located at the other end of the tunnel oven 5; one end of the conveyor belt 3 is connected to the feeding conveyor 2, and the other end is connected to the unloading conveyor 6, and is set corresponding to the vacuum machine 4 and the tunnel oven 5; the automatic guided transport vehicle 1 is used to transport the carrier storing the circuit board to the front of the feeding conveyor 2, so that the feeding conveyor 2 transfers the carrier to the conveyor belt 3, and obtains the defoamed circuit board from the unloading conveyor 6 after the pre-baking is completed, and transports the defoamed circuit board to the next work section.

[0033] The conveyor belt 3 is at the same height as the opening and exit of the vacuum pump 4 and the tunnel oven 5. It can be understood that this connection method is convenient for the transportation of the carrier.

[0034] The conveyor belt 3 includes rollers and belts.

[0035] In this embodiment, the infeed conveyor 2 and the unloading conveyor 6 include a transfer device (not shown), which is used to transfer the carrier from the automatic guided transport vehicle 1 or to the automatic guided transport vehicle 1. The transfer device includes a pallet and a multi-axis robot arm, and the multi-axis robot arm is connected to the bottom of the pallet to drive the pallet to rise, fall or extend.

[0036] Specifically, the automatic guided transport vehicle 1 lifts the carrier and moves the carrier onto the belt of the conveyor belt 3, and transports it through rollers. The pallet of the feed conveyor 2 is raised to the same height as the carrier by the multi-axis robot arm, and the carrier is transferred to the pallet by the extension and retraction of the multi-axis robot arm. The carrier is transported to the vacuum machine 4 via the pallet, so that the vacuum machine 4 vacuums the PCB boards stored on the carrier.

[0037] It can be understood that after the carrier is transported to the feed conveyor 2 by the automatic guided transport vehicle 1, it is directly sent into the vacuum machine 4 through the feed conveyor 2 and the conveyor belt 3, avoiding repetitive labor of personnel and reducing the number of times personnel move frames to 0 times / day. It not only greatly reduces the operating intensity of personnel, but also improves the efficiency of frame moving, and then improves the defoaming efficiency of PCB boards.

[0038] In other embodiments, a lifting robot arm is provided on the side of the vacuum machine 4 close to the automatic guided transport vehicle 1, and the lifting robot arm can be used to directly lift the carrier from the automatic guided transport vehicle 1 and then send it into the vacuum machine 4. This application does not limit this.

[0039] It can be understood that since the vacuum machine 4 and the tunnel oven 5 are connected by the conveyor belt 3, the PCB board can be directly transported to the tunnel oven 5 through the conveyor belt 3 after being processed in the vacuum machine 4, thereby avoiding the automatic guided transport vehicle 1 from performing multiple transportations between the vacuum machine 4 and the tunnel oven 5, and further improving the defoaming efficiency of the PCB board.

[0040] Different from the prior art, the vacuum machine 4 and the tunnel oven 5 of this embodiment are connected in series through the conveyor belt 3, and the feeding conveyor 2 and the unloading conveyor 6 can directly move the frame, which can realize unmanned automatic operation in the thick copper plate defoaming section, which not only reduces the operation intensity of personnel, but also improves the defoaming efficiency; in addition, since the vacuum machine 4 and the tunnel oven 5 are connected by the conveyor belt 3, the automatic guided transport vehicle 1 is avoided from transporting between the vacuum machine 4 and the tunnel oven 5, which further improves the defoaming efficiency.

[0041] Correspondingly, the present application provides a method for automatic defoaming of a circuit board.

[0042] Specifically, see Figure 2 , Figure 2 It is a flow chart of an embodiment of the automatic defoaming method for circuit boards of the present application. In this embodiment, the automatic defoaming method for circuit boards is implemented by an automatic defoaming system for circuit boards, which includes an automatic guided transport vehicle, a feeding conveyor, a conveyor belt, a vacuum pump, a tunnel oven, and a discharge conveyor; the vacuum pump is located at one end of the tunnel oven; the feeding conveyor is located at one end of the vacuum pump; the discharge conveyor is located at the other end of the tunnel oven; one end of the conveyor belt is connected to the feeding conveyor, and the other end is connected to the discharge conveyor, and is arranged corresponding to the vacuum pump and the tunnel oven.

[0043] like Figure 2 As shown, the circuit board automatic defoaming method includes:

[0044] S21: The carrier storing the circuit boards is transported to the infeed conveyor by an automated guided vehicle, and the infeed conveyor transfers the carrier to the conveyor belt.

[0045] In this embodiment, when the automatic guided transport vehicle transports a carrier storing circuit boards, it will automatically read the processing parameters of the circuit boards on the carrier and upload the processing parameters to the MES system, so that the MES system will send the processing parameters to the feeding conveyor, conveyor belt, vacuum machine, tunnel oven and unloading conveyor.

[0046] Among them, the MES (Messaging System) system is an intelligent manufacturing system based on the Internet of Things. It can build a digital factory based on data to drive production management, so as to realize the automation, informatization, transparency and intelligence of the production process.

[0047] In this embodiment, the processing parameters include at least one of a conveying speed, a vacuum degree, a vacuuming time, an oven temperature, a baking time, and an oven type.

[0048] The transmission is divided into four sections: feeding, vacuuming, pre-baking and discharging. The carrier is pushed backward by the front section (feeding section) of the robot arm and pulled backward by the rear section (discharging section) through the transmission form and the conveyor belt to achieve the transmission between sections. Each section is driven by an independent motor, and the transmission speed of each section can be set independently according to needs.

[0049] Among them, when there are multiple tunnel ovens, there are corresponding conveyor belts. At this time, the PCB boards coming out of the vacuum machine need to be diverted into different tunnel ovens, and after pre-baking in different tunnel ovens, they are transmitted through multiple conveyor belts and merged into the unloading conveyor. That is, the transmission is divided into 6 sections: feeding, vacuuming, diversion, pre-baking, merging and discharging.

[0050] Specifically, in the intelligent manufacturing mode, after the installation is completed, that is, after the vacuum machine and the tunnel oven are connected in series through the connection equipment, the processing parameters of each section of the thick copper plate defoaming section can be controlled through the MES system. The processing methods of PCB boards transported by different carriers are different, and the corresponding processing parameters are different. After reading the processing parameters of different PCB boards, the automatic guided transport vehicle uploads them to the MES system. The MES system controls the vacuum time of the vacuum machine and the baking time of the tunnel oven according to the processing parameters.

[0051] S22: The carrier is transported into a vacuum machine through a transmission belt, the circuit board on the carrier is vacuumed by the vacuum machine, and after the vacuuming is completed, the carrier is transported into a tunnel oven through a conveyor belt, the circuit board is pre-baked in the tunnel oven, and after the pre-baking is completed, the carrier is transported into a discharge conveyor through a conveyor belt.

[0052] In this embodiment, there are one or more tunnel ovens, and there are one or more corresponding conveyor belts.

[0053] When there are multiple tunnel ovens, the MES system also needs to control the transportation direction of the conveyor belt to divert different PCB boards to different ovens and control the baking time of each tunnel oven.

[0054] Specifically, when there are multiple tunnel ovens, the carrier is transported into a vacuum machine via a transmission belt, the circuit board on the carrier is vacuumed by the vacuum machine, and after the vacuuming is completed, the carrier is diverted by multiple conveyor belts according to different processing parameters to transport the carriers with different processing parameters into the corresponding tunnel ovens, the circuit boards are pre-baked by multiple tunnel ovens, and after the pre-baking is completed, the carrier is transported into the unloading conveyor by multiple conveyor belts.

[0055] S23: The carrier is transferred to the automatic guided transport vehicle through the unloading conveyor, so that the automatic guided transport vehicle obtains the defoamed circuit board, and the defoamed circuit board is transported to the next work section through the automatic guided transport vehicle.

[0056] Different from the prior art, this embodiment connects the vacuum machine and the tunnel oven in series through a connecting device, and replaces the manual frame moving by the feeding conveyor and the unloading conveyor, so as to realize unmanned automatic operation in the thick copper plate defoaming section, which not only reduces the operation intensity of personnel, but also improves the defoaming efficiency; in addition, since the vacuum machine and the tunnel oven are connected by a conveyor belt, the automatic guided vehicle is avoided to transport between the vacuum machine and the tunnel oven, which further improves the defoaming efficiency.

[0057] Correspondingly, the present application provides an automatic defoaming device for a circuit board.

In addition to the processor 32 and the memory 31, the circuit board automatic defoaming device 30 can also include a touch screen, a communication circuit, etc. according to requirements, which are not limited here.

[0060] Specifically, the processor 32 is used to control itself and the memory 31 to implement the steps in any of the above-mentioned trajectory acquisition method embodiments.

[0062] Correspondingly, the present application provides a computer-readable storage medium.

[0063] See also Figure 4 , Figure 4 It is a structural schematic diagram of an implementation method of a computer-readable storage medium of the present application.
