Description

Technical Field

[0001] The utility model belongs to the technical field of PCBA dispensing, and in particular relates to a lithium battery PCBA automatic white glue dispensing and detection device. Background Art

[0002] During the manufacturing and installation of battery motherboards, a combination of gluing and screw fixing is usually adopted. Therefore, before installation, the motherboard needs to be glued, and a glue dispensing machine is needed for glue dispensing. The glue dispensing machine uses tools such as glue valves and needles to apply glue at designated locations. The glue dispensing machine is an automated machine with internal movable components that can achieve three-dimensional glue dispensing. It has the characteristics of precise positioning, precise glue control, no wire drawing and no glue leakage. Most of the glue dispensing machines currently used directly place the objects to be glued on the glue dispensing table. When the glue dispensing table moves, the mobile phone motherboard placed on it may move slightly due to inertia, which may cause the glue dispensing position to have some deviation. In addition, the switch button is external, and the staff may accidentally touch the switch button of the equipment due to negligence during operation, thereby stopping the equipment and restarting it, affecting the glue dispensing efficiency.

[0003] To this end, a mobile phone motherboard dispensing device with the announcement number "CN215878600U" includes a base, a control panel is installed above the base, and a Z-axis moving component is installed above the control panel, a dispensing platform is installed above the Z-axis moving component, bottom columns are installed on both sides of the Z-axis moving component, and a rotating part is installed above the bottom column, an adjusting plate is installed at the end of the rotating part away from the bottom column, and a pressure spring is installed between the adjusting plate and the bottom column. The utility model is provided with a bottom column, and the adjusting plate is installed through the rotating part, a pressure spring is installed on the bottom wall of the adjusting plate, and a slide rail is provided under the bottom wall away from the pressure spring, and a pressing part is installed under the slide rail, which drives the adjusting plate to be pressed down by the pressure spring to transfer the pressure to the pressing part, and the mobile phone motherboard is pressed with the help of the pressing part to fix it, so as to prevent the mobile phone motherboard from moving due to inertia when the dispensing platform is moving.

[0004] However, for the above-mentioned mobile phone motherboard dispensing device, although the elastic force of the pressure spring will drive the adjustment plate to rotate downward with the rotating part as the center, so that the pressing part is close to the dispensing table, and the mobile phone motherboard is fixed with the help of the pressing part under the adjustment plate to avoid the mobile phone motherboard from moving slightly due to inertia when the dispensing table is moving, there are still the following more obvious defects during use: although the above-mentioned dispensing table can perform single-sided dispensing on the motherboard workpiece, since there is no flipping component, it needs to be manually flipped to perform dispensing on the other side. The manual flipping method can easily cause the motherboard workpiece to change its position when placed on the dispensing table, resulting in the problem of dispensing offset. Utility Model Content
