[0033] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] A dispensing process assembly table includes a weighing module 1, a calibration module 2, a height measuring component 22, and a position calibration component 23. The weighing module 1 is used to weigh the weight of dispensing glue in a single dispensing cycle, and the calibration module 2 is used to calibrate the dispensing volume.

[0036] The weighing module 1 is installed in a cavity within the dispensing equipment platform. The weighing module 1 includes a mounting base 11, a sealing cover 12, a weighing component 13, and a pressure cap assembly 14. The mounting base 11 is connected to the inner wall of the cavity. The weighing component 13 is mounted on the mounting base 11, and the sealing cover 12 covers the weighing component 13. The sealing cover 12 has a glue inlet. The pressure cap assembly 14 is mounted on the mounting base 11 and can block the glue inlet when the weighing component 13 is weighing. The weighing component 13 includes a weighing body and a glue cup. The weighing body has a weighing pan. Both the glue cup and the weighing pan are located inside the sealing cover 12. The glue cup is positioned on the weighing pan and is located directly below the glue inlet.

[0037] When the dispensing valve is directly above the glue inlet, the glue drips into the glue cup under gravity, and the amount of glue dispensed is then weighed using a weighing pan. The capping assembly 14 includes a drive module and a cap, with the cap connected to the output of the drive module. The drive module can be a pneumatic slide. When glue dispensing is required, the drive unit moves the cap away from the glue inlet. After dispensing is complete, the cap moves to cover the glue inlet. Weighing is then performed after the cap covers the glue inlet. During weighing, the sealing of the weighing assembly 13 is improved to isolate the influence of external wind, magnetic fields, etc., on the weighing assembly 13, thereby improving weighing accuracy.

[0038] It should be noted that the outer wall of the sealing cover 12 is equipped with a positive pressure air blowing connector and a vacuum negative pressure connector, both of which are connected to the inner cavity of the sealing cover 12. The positive pressure air blowing connector and the vacuum negative pressure connector utilize positive pressure gas blowing from the glue head and negative pressure gas drawing from the inner cavity, respectively, to ensure that the adhesive moves along the downward flow direction of the gas, facilitating the peeling of the adhesive from the glue head.

[0039] The sealing cover 12 is mounted on the weighing assembly 13 via a pressure plate. Fixing plates are provided on both sides of the weighing assembly 13; the lower ends of the fixing plates are connected to the mounting base 11, and the two ends of the pressure plate are connected to the upper ends of the fixing plates. This facilitates the installation and removal of the weighing assembly 13.

[0040] The calibration module 2 includes a weight calibration component 21. The weight calibration component 21, height measuring component 22, and position calibration component 23 are all mounted on the working surface of the dispensing equipment platform. The position calibration component 23 is positioned between the height measuring component 22 and the weight calibration component 21. It should be noted that the number of weight calibration components 21, height measuring components 22, and position calibration components 23 can be set multiple times according to actual usage requirements. In this embodiment, there are two calibration modules 2, corresponding to two dispensing valves arranged along the X-axis. To save space, the dispensing valves share one height measuring component 22. That is, along the X-axis, the weight calibration component 21, position calibration component 23, height measuring component 22, position calibration component 23, and weight calibration component 21 are arranged sequentially. The weighing module 1 and the height measuring component 22 are arranged along the Y-axis.

[0041] The weight calibration component 21 includes a base 211 and a weighing platform 212. The base 211 is mounted on the dispensing equipment platform, and a mounting groove is provided on the top surface of the base 211. The weighing platform 212 is detachably mounted in the mounting groove. One or two inner sidewalls of the mounting groove are spaced apart from the weighing platform 212. In this embodiment, two opposite sidewalls of the mounting platform abut against the inner sidewall of the mounting groove, while the other two opposite sidewalls are spaced apart from the inner sidewall of the mounting groove. This design both limits the position of the weighing platform 212 and facilitates its removal from the mounting groove. In other embodiments, the base 211 may also have a notch communicating with the mounting groove. The weighing platform 212 is then engaged in the mounting groove, with all four sidewalls abutting against the inner sidewall of the mounting groove. The notch facilitates the removal of the weighing platform 212 from the mounting groove.

[0042] The position calibration component 23 includes a base 231, a height measuring sensor 232, and a calibration plate. The height measuring sensor 232 and the calibration plate are mounted on the dispensing equipment platform via the base 231. The height measuring sensor 232 is located on one side of the calibration plate and is adapted to the sensor on the dispensing valve. The height measuring sensor 232 can be used to measure the height of the dispensing valve.

[0043] The height measuring component 22 includes a fixed base 221 and a height measuring platform 222. The height measuring platform 222 is installed on the dispensing equipment platform through the fixed base 221. The top surface of the height measuring platform 222 is provided with multiple height measuring surfaces 223. The multiple height measuring surfaces 223 form a stepped shape with the height changing sequentially along the horizontal movement direction of the dispensing valve. In this application, the height measuring surfaces 223 are provided with four different heights.

[0044] The control dispensing valve passes sequentially above the position calibration component 23 and the height measuring component 22. After the sensor on the dispensing valve is aligned with the height measuring sensor 232 on the position calibration component 23, the position of the dispensing valve nozzle is calibrated by the calibration plate. Then, the calibration of the working height of the dispensing valve is improved by using a step-up or step-down height measuring method.

[0045] Then, control the dispensing valve to move above the weight calibration component 21 and the weighing module 1. The dispensing valve outputs a fixed amount of glue to the weighing platform 212 and the glue cup. For example, when glue is output to the weighing platform 212, the weight measured in the glue cup is W1. The weighing platform 212 is removed and placed on an external standard scale, and the weight measured is W2. Compare W1 and W2. If W1 is not equal to W2, the weighing accuracy of the glue cup needs to be adjusted.

[0046] Based on the commonly used weighing module 1, this application adds a calibration module 2. The calibration module 2 can perform weight calibration on the dispensing volume against a standard weighing device. By comparing the weighing of the calibration module 2 with that of the weighing module 1, the accuracy of the weighing module 1 can be calibrated in a timely manner, thereby ensuring the accuracy of the dispensing volume each time and improving the dispensing quality.
