[0041] Specifically, as Figure 1 、 3 shown, the top of the positioning fixture 1 is provided with a detachable tooling bottom plate 31 made of POM material. The product to be dispensed is placed and positioned on the tooling bottom plate 31, and different tooling bottom plates 31 can be replaced based on different products to meet production requirements.

[0042] Specifically, as Figures 1 to 2As shown in the figure, the gantry dispensing mechanism 2 is located on one side of the positioning tooling 1 and is used to dispense glue on the product to be dispensed on the positioning tooling 1. The gantry dispensing mechanism 2 includes: a gantry moving module and a dispensing component 22. The gantry moving module is arranged on one side of the positioning tooling 1 and provides the driving force for moving in the X, Y, and Z axes; the dispensing component 22 is arranged at the output end of the gantry moving module and dispenses glue on the product to be dispensed on the positioning tooling 1 under the drive of the gantry moving module.

[0043] Furthermore, as Figures 1 to 2 shown, the gantry moving module includes: four columns 211, two Y-axis high-precision modules 212, an X-axis high-precision module 213, and a Z-axis high-precision module 214. The four columns 211 are arranged outside the positioning tooling 1; one of the Y-axis high-precision modules 212 is arranged on two of the columns 211, and the other Y-axis high-precision module is arranged on the other two columns 211 to provide the driving force for Y-axis movement; the X-axis high-precision module 213 is arranged at the output ends of the two Y-axis high-precision modules 212 to provide the driving force for X-axis movement; the Z-axis high-precision module 214 is arranged at the output end of the X-axis high-precision module 213, and the output end of the Z-axis high-precision module 214 is connected to the dispensing component 22.

[0044] Specifically, as Figure 1 , 3 shown, the automatic weighing mechanism 3 is connected to the positioning tooling 1 and is used to weigh the product after dispensing glue on the positioning tooling 1 to judge the quality of the dispensing. The automatic weighing mechanism 3 includes: a bottom plate 31, a weighing sensor 32, a weighing plate 33, at least two small linear bearings 34, at least two guide columns 35, a driver 36, a lifting plate 37, four large linear bearings 38, and four jacking shafts 39. The weighing sensor 32 is arranged on the bottom plate 31; the weighing plate 33 is arranged on the weighing sensor 32; at least two small linear bearings 34 are arranged on both sides of the weighing plate 33; the tops of at least two guide columns 35 penetrate through at least two small linear bearings 34 one by one and are connected to the bottom of the positioning tooling 1; the driver 36 is arranged at the bottom of the bottom plate 31, and the driver 36 is a cylinder; the lifting plate 37 is arranged at the output end of the driver 36; four large linear bearings 38 are arranged on both sides of the bottom plate 31; the bottoms of the four jacking shafts 39 are all connected to the top of the lifting plate 37, and the tops of the four jacking shafts 39 penetrate through the four large linear bearings 38 one by one and abut against the positioning tooling 1.

[0045] Working principle:

[0046] The driver 36 operates to drive the lifting plate 37 and the four jacking shafts 39 to jack up, lifting the positioning tooling 1 and disengaging it from the weighing plate 33, so that the positioning tooling 1 is in a high position. Then place the product on the positioning tooling 1 for positioning. Then control the driver 36 to operate, driving the lifting plate 37 and the four jacking shafts 39 to move downward. Under the action of the guiding columns 35, the positioning tooling 1 falls onto the weighing plate 33 by its own weight. At this time, the weighing sensor 32 records the current weight. The gantry moving module drives the dispensing assembly 22 to dispense glue on the product. After the dispensing is completed, the weighing sensor 32 weighs again and records the weight after dispensing. The numerical difference between the weights before and after dispensing is used to determine whether the dispensing is OK this time!
