Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit board plugging holes, in particular to a 5-cavity vacuum automatic alignment printing device. Background Art

[0002] PCB circuit board printing refers to the process of printing circuit patterns, text or logos on PCB. By coating the surface of PCB with conductive ink or solder mask ink and scraping off the excess ink with a scraper, the required pattern is printed on the surface of PCB. The printed patterns include wires, pads, component logos, etc., and these patterns are the key to realize circuit connection and component installation.

[0003] However, in the existing printing process, some steps adopt a semi-automatic production method, which means that in the production process, some operations require manual intervention and control, and manual alignment makes the processing efficiency low. Therefore, a 5-cavity vacuum automatic alignment printing device is proposed;

[0004] To solve the above problems, this paper proposes a 5-cavity vacuum automatic registration printing device. Utility Model Content

[0005] The main purpose of the utility model is to provide a 5-cavity vacuum automatic registration printing device, which can effectively solve the technical problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cavity vacuum automatic alignment printing device comprises a PCB board feeding bin, a CCD positioning bin, a printing bin, a PCB board transfer bin and a PCB board discharging bin, wherein the PCB board feeding bin, the CCD positioning bin, the printing bin, the PCB board transfer bin and the PCB board discharging bin are connected in sequence, a vacuum system is arranged behind the PCB board feeding bin, and a vacuum cavity is arranged below the PCB board feeding bin, the CCD positioning bin, the printing bin, the PCB board transfer bin and the PCB board discharging bin.

[0008] As a further solution of the utility model, the PCB board feeding bin, CCD positioning bin, printing bin, PCB board transfer bin, and PCB board discharging bin are all provided with CCD positioning mechanisms.

[0009] As a further solution of the utility model, a group of flap-type vacuum sealing doors are arranged inside the CCD positioning bin, and a PCB board handling robot is arranged inside the CCD positioning bin.

[0010] As a further solution of the utility model, a screen printing group is arranged in the printing chamber, and a screen printing platform is also arranged in the printing chamber.

[0011] As a further solution of the utility model, an automatic ink adding mechanism is arranged on one side of the screen printing platform, and the automatic ink adding mechanism is also located in the printing chamber.

[0012] As a further solution of the utility model, another set of flap-type vacuum sealing doors is provided on the inner side of the PCB board discharge bin, and a vertical vacuum sealing door is provided on one side of the outer side of the PCB board discharge bin.

[0013] The beneficial effects of the utility model are as follows:

[0014] This equipment is fully automatic throughout the entire process. During processing, the PCB board feed bin is connected to the automatic board loading machine. After receiving the PCB circuit board, the PCB circuit board is automatically aligned and printed. After printing, it is automatically taken out of the bin. The entire process does not require manual loading, alignment, and unloading, avoiding the need for manual operation to affect processing efficiency.

[0015] This device is equipped with an automatic ink adding mechanism. When the sensor on the printing group detects that the ink is too little, the automatic ink adding mechanism will automatically add ink without opening the cavity. At the same time, the cycle of wiping the bottom of the screen can also be set, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-2As shown, a 5-cavity vacuum automatic alignment printing device includes a PCB board feeding bin 1, a CCD positioning bin 2, a printing bin 3, a PCB board transfer bin 4, and a PCB board discharge bin 5. The PCB board feeding bin 1, the CCD positioning bin 2, the printing bin 3, the PCB board transfer bin 4, and the PCB board discharge bin 5 are connected in sequence, a vacuum system 7 is arranged behind the PCB board feeding bin 1, and a vacuum cavity 8 is arranged below the PCB board feeding bin 1, the CCD positioning bin 2, the printing bin 3, the PCB board transfer bin 4, and the PCB board discharge bin 5.

[0021] By setting up five groups of bins including PCB board feeding bin 1, CCD positioning bin 2, printing bin 3, PCB board transfer bin 4 and PCB board discharging bin 5, the printing process of PCB circuit boards is made smoother and more coherent, and the whole process is in full-automatic mode, which is convenient for PCB circuit board processing.

[0022] In this embodiment, the PCB board feeding bin 1 , the CCD positioning bin 2 , the printing bin 3 , the PCB board transfer bin 4 , and the PCB board discharging bin 5 are all provided with a CCD positioning mechanism 6 .

[0023] The CCD positioning mechanism 6 can automatically position the PCB circuit board, eliminating the need for manual alignment and improving work efficiency.

[0024] In this embodiment, a set of flap-type vacuum sealing doors 10 are arranged inside the CCD positioning chamber 2 , and a PCB board handling robot 11 is arranged inside the CCD positioning chamber 2 .

[0025] The PCB board transport robot 11 can transport the PCB circuit boards processed internally.

[0026] In this embodiment, a screen printing group 12 is disposed in the printing chamber 3 , and a screen printing platform 14 is also disposed in the printing chamber 3 .

[0027] The screen printing group 12 and the screen printing platform 14 in the printing chamber 3 are both components for printing and processing PCB circuit boards for CB circuit boards.

[0028] In this embodiment, an automatic ink adding mechanism 13 is disposed on one side of the screen printing platform 14 , and the automatic ink adding mechanism 13 is also located in the printing chamber 3 .

[0029] The automatic ink adding mechanism 13 can automatically add ink without opening the cavity when adding ink.

[0030] In this embodiment, another set of flap-type vacuum sealing doors 10 are provided inside the PCB board discharge bin 5 , and a vertical vacuum sealing door 9 is provided on one side outside the PCB board discharge bin 5 .

[0031] The flap-type vacuum sealing door 10 of the PCB board discharge bin 5 is located at the connection with the PCB board transfer bin 4, and the vertical vacuum sealing door 9 is located at the discharge of the PCB board discharge bin 5 for discharging PCB circuit boards.

[0032] It should be noted that the utility model is a 5-cavity vacuum automatic alignment printing device. When in use, first, the PCB board feeding bin 1 is connected to the automatic board loading machine, and then the PCB board feeding bin 1 automatically closes the bin door and starts vacuuming. When the vacuum value is consistent with the printing bin 3, the PCB board will flow into the CCD positioning bin 2 for positioning. The PCB board entering the CCD positioning bin 2 will be automatically corrected and sent to the printing cavity to complete printing. After printing is completed, the PCB board passes through the PCB board transfer bin 4 and finally automatically exits from the PCB board discharge bin 5, thereby completing the entire printing process.

[0033] At the same time, the printing group can set a period of wiping the bottom of the screen. When the sensor on the printing group detects that the ink is too little, the automatic ink adding mechanism 13 will start and automatically add ink.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
