Description

Technical Field

[0001] The present application relates to the field of PCBA processing technology, and in particular to a dispensing machine for PCBA production. Background Art

[0002] PCBA boards, also known as printed circuit boards, are important electronic components, supporting electronic components and providing circuit connections for them. During the PCBA board manufacturing process, to enhance the reliability of the board, the components and solder joints on the board are typically glued. This ensures the board's waterproof, dustproof, and corrosion-resistant properties. Glue dispensing has become an essential process in PCBA board production.

[0003] Currently, in the PCBA dispensing machine used, after dispensing the circuit board, the dispensing head needs to be cleaned to prevent the glue inside the head from solidifying and clogging the head. Most cleaning methods are to first perform multiple empty strokes to remove the remaining glue in the head. However, some glue may still remain on the outside of the head, sticking to the head outlet and near the outlet. If it is not cleaned, it will also affect the dispensing of the head. Therefore, a dispensing machine for PCBA production is designed to solve the above-mentioned problems. Utility Model Content

A first drive assembly 2 is mounted on both sides of the upper end of the fixed base 1. A mounting plate 3 is provided on the first drive assembly 2, and a second drive assembly 4 is mounted on the upper end of the mounting plate 3. A hydraulic cylinder 5 is mounted on the second drive assembly 4, and a dispensing head 6 of the dispensing machine is fixedly mounted on the lower end of the hydraulic cylinder 5. The first drive assembly 2 is composed of common moving components in the field, such as a drive motor and threaded rods. It is the lateral moving component used for moving the dispensing machine, namely the X-axis drive. The second drive assembly 4 is an electric drive, namely the Y-axis drive. Both are common technical means in the field and are not described in detail.

[0022] One side of the mounting plate 3 is fixedly connected to the support plate 8, and a cleaning bucket 9 is provided on the upper end of the support plate 8. The outer side of the cleaning bucket 9 is fixedly connected to the gear ring 16. One side of the gear ring 16 engages with the No. 2 gear 15. The No. 2 gear 15 drives the gear ring 16 to rotate, so that the gear ring 16 drives the cleaning bucket 9 to rotate and wipes and cleans the outside of the dispensing head inserted into the cleaning bucket 9.

[0023] By adopting the above technical solution, the lower end of the cleaning bucket 9 is rotatably connected to the swivel 92, the lower end of the swivel 92 is fixedly connected to the spring 91, and the lower end of the spring 91 is fixedly connected to the support plate 8. The provided spring 91 is used to push the cleaning bucket 9 to rise and return to its original position.
