Description

Technical Field

[0001] The invention belongs to the technical field of glue dispensing, and in particular relates to a mold clamping device for a glue dispensing mold. Background Art

[0002] Glue dispensing is to use a glue dispenser or glue gun to dispense glue at the location where glue is needed. Currently, many electronic products need glue dispensing to achieve connection and sealing. For example, the sealing cover of a mobile phone needs glue dispensing to achieve a sealed connection. For another example, the back panel of a display screen needs glue dispensing.

[0003] At present, the glue dispensing of electronic products is generally done by using an automated glue dispensing machine. For example, the Chinese patent document with publication number CN111495691B discloses a fully automatic, efficient and high-precision glue dispensing machine, including a machine body, a conveyor line is provided on the machine body, and the conveyor line is used to convey the workpiece; a glue dispensing station is provided on the conveying end face of the conveyor line; a glue dispensing component, including a glue needle and a glue needle driving mechanism, and the glue needle driving mechanism is used to drive the glue needle to move along the X-axis direction, the Y-axis direction and the Z-axis direction; the glue dispensing station is located on the movement trajectory of the glue needle; a detection component, including a weighing platform and a weighing sensor, and the weighing sensor is arranged at the bottom end of the weighing platform, and the weighing sensor is arranged at the bottom end of the weighing platform. The platform is located on the movement track of the glue needle; the weighing platform is used to receive the glue liquid from the glue needle; the weighing sensor is used to detect the weight of the glue liquid on the weighing platform and transmit the weight signal; the glue needle driving mechanism is used to drive the glue needle to move according to the weight signal;] The calibration component includes a calibration platform, an X-axis calibrator, a Y-axis calibrator and a Z-axis calibrator; the X-axis calibrator is used to calibrate the glue needle in the X-axis direction; the Y-axis calibrator is used to calibrate the glue needle in the Y-axis direction; the Z-axis calibrator is arranged on the calibration platform and is used to calibrate the glue needle in the Z-axis direction. Its glue needle driving mechanism can drive the glue needle to move in the X-axis direction and the Y-axis direction to the workpiece position, and the glue needle can adjust the dispensing height when it moves in the Z-axis direction to complete the dispensing.

[0004] In the above patent document, glue dispensing is completed by translating the glue nozzle. However, during the glue dispensing process, there will be a time difference in the glue discharge, which will cause a joint mark at the connection position of the head and tail of the glue, affecting the quality of glue dispensing.
