Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a glue dispensing fixture and a glue dispensing machine. Background Art

[0002] When dispensing glue on a product, a dispensing machine uses a dispensing jig to hold the product, and then uses a three-dimensional motion mechanism to move the dispensing head to apply glue. Currently, dispensing jigs generally only hold the product in place, while the three-dimensional motion mechanism only moves the dispensing head in a linear manner. When dispensing glue on the sides of a product, the dispensing jig must be manually moved or the product must be flipped to achieve glue application from all angles. Frequent jig movement and product flipping results in high labor intensity and cumbersome operation, which affects dispensing efficiency.

[0029] The dispensing station 4 includes an adsorption plate 41, a fixed seat 42 and a second rotating shaft 43. The fixed seat 42 is fixedly connected to the top surface of the adjustment plate 3. The adsorption plate 41 is arranged on the top of the fixed seat 42 for adsorbing the product; the second rotating shaft 43 passes through the fixed seat 42, the top end is connected to the adsorption plate 41, the end passes through the adjustment plate 3 and is connected to the driving wheel 44; the driving device 5 is connected to the adjustment plate, which includes a rotating motor 51, the rotating shaft of the rotating motor 51 passes through the adjustment plate 3, and is connected to the rotating wheel 52 at the end. The rotating wheel 52 and the driving wheel 44 are connected and transmitted by a transmission belt 53, so that the rotating motor 51 can drive the second rotating shaft 43 to rotate, thereby driving the adsorption plate 41 to rotate.

[0030] Furthermore, a tension adjustment device 54 is provided at the bottom of the adjustment plate 3. The tension adjustment device 54 abuts against the transmission belt 53 and is used to adjust the tension of the transmission belt 53. A protective shell 55 is also provided at the bottom of the adjustment plate 3. The drive wheel 44, rotating wheel 52, transmission wheel 53, and tension adjustment device 54 are all placed within the protective shell 55 to prevent the drive components from being impacted and affecting operation.
