Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board painting equipment, and in particular relates to a light-assisted error prevention device for circuit board painting. Background Technology

[0002] In the electronics manufacturing industry, PCB boards are one of the core components of electronic devices. Before PCB boards go into production, they are usually coated with conformal coating for protection. The coating thickness standard not only affects the protective performance of the circuit board, but also determines many factors such as the production cost, safety, and reliability of electronic devices. Different coating processes result in variations in the thickness of the conformal coating on PCBs. For example, in the spray coating process, the degree of paint atomization, the distance between the spray gun and the PCB, and the spraying speed all affect the thickness of the conformal coating deposited on the PCB surface. Manual brushing requires precise operation by the operator to achieve uniform coating. In addition, during the coating process, it is necessary to avoid grounding screw mounting holes, but existing circuit board painting equipment generally cannot easily mark the locations of mounting holes, which makes it easy for operators to make mistakes during the coating process, which is not conducive to improving the coating effect and coating quality.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A light-assisted error-proofing device for circuit board painting, such as Figure 1 and Figure 2 As shown, the device includes a device platform 1, a guide support column 3 and an illuminated support column 5 mounted on the device platform 1. The device platform 1 is equipped with a magnetic plate 2. The guide support column 3 and the illuminated support column 5 are each equipped with a magnetic block 12 that can cooperate with the magnetic plate 2. The guide support column 3 is equipped with a detachable connector 4. The illuminated support column 5 is equipped with an indicator light 6. The device platform 1 is equipped with a power supply 13 that supplies power to the indicator light 6. The indicator light 6 is detachably connected to the power supply 13 via a power supply line 7.

[0026] For example, the magnetic plate 2 can be installed on the equipment platform 1 by conventional means such as screws, and the indicator light 6 can also be installed on the lamp support column 5 by conventional means such as screws. The indicator light 6 can be an LED light, and the power supply 13 can be a 5V DC power supply commonly used for existing LED lights, and can be installed on the equipment platform 1 by conventional means such as screws. Those skilled in the art can also select a suitable indicator light 6 and its matching power supply 13 according to actual needs to achieve power supply control of the indicator light 6. This utility model does not involve the improvement of the indicator light 6 and the power supply 13 themselves, so it will not be described in detail here.

[0027] In practical applications, operators can use the connectors 4 on the guide support column 3 to mate with the holes on the circuit board to limit and support the circuit board. Then, the operator can move the illuminated support column 5 to the location of the grounding screw mounting hole on the circuit board to mark the hole. During coating, the operator can easily locate the grounding screw mounting hole using the indicator light 6, thus avoiding coating the grounding screw mounting hole separately. Only the position of the illuminated support column 5 needs to be adjusted once per batch, making the operation very simple.

[0028] Preferably, the power supply unit 13 is provided with multiple power supply ports 9. One end of the power supply line 7 is provided with a power supply plug 8 that can be plugged into the power supply port 9, and the other end is connected to the power supply terminal of the indicator light 6. Exemplarily, both the power supply plug 8 and the power supply port 9 can be existing components, and the use of the power supply plug 8 to cooperate with the power supply port 9 is also prior art. By using a power supply unit 13 with multiple power supply ports 9 and utilizing the power supply plug 8 to cooperate with the power supply port 9, the power supply connection between the power supply unit 13 and the indicator light 6 is realized, making it convenient for operators to select an appropriate number of lamp support columns 5 for installation.

[0029] Preferably, the outer diameter of the magnetic block 12 is larger than the diameter of the guide support column 3 and the illuminated support column 5. For example, the magnetic block 12 can be installed and fixed to the guide support column 3 or the illuminated support column 5 using conventional methods such as adhesives. By utilizing the magnetic block 12 and the magnetic plate 2, the guide support column 3 and the illuminated support column 5 can be conveniently installed and fixed on the equipment platform 1. Furthermore, operators can easily adjust the positions of the guide support column 3 and the illuminated support column 5 according to actual needs to accommodate different circuit boards, thus improving the applicability and ease of use of this device.

[0030] In practical applications, the magnetic block 12 is a disc-shaped structural component. By setting the outer diameter of the magnetic block 12 to be larger than the diameter of the guide support column 3 and the lamp-lit support column 5, and by adopting a disc-shaped structural component, the magnetic block 12 can form a stable inverted T-shaped structure with the guide support column 3 or the lamp-lit support column 5, which is beneficial to improving the stability of the guide support column 3 and the lamp-lit support column 5.

[0031] Preferably, the illuminated support column 5 includes an upper half and a lower half, which are threaded together. For example, the lower half has an external thread, and the upper half has a threaded groove that mates with the external thread. By adopting a split structure for the illuminated support column 5, the operator can easily adjust the length of the illuminated support column 5 by screwing on the upper and lower half, thereby adjusting the height of the indicator light 6 so that the indicator light 6 can better mark the grounding screw mounting holes on the circuit board.

[0032] Preferably, at least four guide support columns 3 are evenly arranged around the equipment platform 1. For example, four or more guide support columns 3 can be evenly arranged. Those skilled in the art can select an appropriate number for installation according to actual needs. By setting at least four guide support columns 3 to support the circuit board, the stability of the circuit board can be improved, making it easier for operators to perform coating operations, and also helping to improve the coating effect.

[0033] Preferably, the equipment platform 1 is provided with multiple storage slots 10 for storing the lamp support column 5. By providing multiple storage slots 10 on the equipment platform 1, unused lamp support columns 5 can be inserted into the storage slots 10 for storage. The diameter of the storage slot 10 must be larger than the diameter of the lamp support column 5 in order to accommodate the lamp support column 5 and the power supply line 7.

[0034] In practical applications, a magnetic ring 11 is provided on the device platform 1 at the position corresponding to the opening of the storage slot 10, which can cooperate with the magnetic block 12. For example, the magnetic ring 11 can be installed on the device platform 1 by conventional means such as screws. By using the magnetic ring 11 to cooperate with the magnetic block 12 on the lamp support column 5, the lamp support column 5 can be magnetically fixed, ensuring that the lamp support column 5 is not easy to fall out of the storage slot 10.

[0035] Preferably, the connector 4 and the guide support column 3 are connected by a thread. For example, the guide support column 3 has an external thread, and the connector 4 has a threaded groove that mates with the external thread. By using a threaded connection, operators can easily replace connectors 4 of different shapes and specifications according to actual needs. Furthermore, the height of the connector 4 can be adjusted appropriately by screwing it on, thus better supporting the circuit board and preventing the indicator light 6 from contacting the circuit board.

[0036] This utility model discloses a light-assisted error-proofing device for circuit board painting, which has the advantages of simple structure, easy adjustment and use, and good applicability. It can be used for circuit board coating and can clearly mark the holes such as grounding screw mounting holes on the circuit board, which helps to reduce the coating of holes due to operator error. By using magnetic blocks and magnetic plates, the guide support column and the illuminated support column can be easily installed and fixed on the equipment platform. The operator can also easily adjust the position of the guide support column and the illuminated support column according to actual needs to adapt to different circuit boards, which improves the applicability and convenience of this device.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
