[0022] The following will be described in detail with specific embodiments.

[0023] Reference Figs. 1 to 3 The embodiment of the present application provides a double-stage pressure stabilizing device (hereinafter referred to as device) for a glue dispensing device to ensure the stability of the glue dispensing amount of the glue dispensing device.

[0024] As shown in Figs. 1 to 3 The device of the present application can be connected in series between the glue bucket and the air source of the glue dispensing device, comprising: a gas storage cylinder 10 connected to the glue bucket of the glue dispensing device, and a first precision pressure reducing valve 11 connected to the gas storage cylinder 10; wherein the first precision pressure reducing valve 11 is used for first pressure stabilizing control of the air pressure, that is, for pressure stabilizing control of the air pressure from the air source to the gas storage cylinder 10, and the gas storage cylinder 10 has a buffering and isolation effect, which can perform second pressure stabilizing control on the air pressure.

[0025] In some optional embodiments, the device of the present application further comprises: an air pressure inlet pipe 12 connected to the first precision pressure reducing valve 11, for connecting the air source outside the first precision pressure reducing valve 11.

[0026] In some optional embodiments, the device of the present application further comprises: a glue bucket outlet pipe 13 arranged on the gas storage cylinder 10, for connecting the glue bucket to the gas storage cylinder 10.

[0027] In some optional embodiments, the air pressure inlet pipe 12 and the glue bucket outlet pipe 13 are both arranged on the top of the gas storage cylinder 10, to ensure the smoothness of the air path.

[0028] In some optional embodiments, the top of the gas storage cylinder 10 has a first opening, and the first precision pressure reducing valve 11 is connected in series between the first opening and the air pressure inlet pipe 12.

[0029] In some optional embodiments, the top of the gas storage cylinder 10 has a second opening, and the glue bucket outlet pipe 13 is connected to the second opening.

[0030] In some optional embodiments, the gas storage cylinder 10 can be a horizontally placed cylinder, which can be a sealed cylinder, such as a sealed metal cylinder or a plastic cylinder.

[0031] In some alternative embodiments, the gas cylinder 10 can be configured with multiple gas outlet pipes 13 connected to multiple glue barrels of multiple glue applying devices. That is, the device of the present application can be used with one glue applying device or multiple glue applying devices.

[0032] In some alternative embodiments, the device of the present application further comprises a second precision pressure reducing valve (not shown in the figure) connected between the gas cylinder 10 and the glue barrel of the glue applying device, for performing three times of pressure stabilizing control, that is, performing pressure stabilizing control again before the gas enters the glue barrel.

[0033] In some embodiments of the present application, a glue applying system for a loudspeaker is also provided, which comprises a glue applying device and a glue applying two-stage pressure stabilizing device as described above.

[0034] In the embodiments of the present application, the gas from the gas source is first stabilized by the first precision pressure reducing valve 11, then enters the gas cylinder 10 for buffering and further stabilizing, and finally enters the glue barrel of the glue applying device to push the glue applying device to perform glue applying work. Before the gas in the gas cylinder 10 enters the glue barrel of the glue applying device, it can be stabilized again by the second precision pressure reducing valve, further improving the pressure stability of the gas entering the glue applying device.

[0035] Generally, the gas from the gas source is quite unstable, and if directly introduced into the glue barrel of the glue applying device, it will cause great changes in the glue output, making it difficult for the glue applying device to work normally. In conventional applications, a pressure reducing valve can be provided on the glue barrel for pressure stabilizing, but due to the great changes in the gas pressure of the gas source, the pressure reducing valve is greatly impacted, making it difficult to ensure that the gas pressure is stabilized in the required range even if there is a pressure reducing valve, and unable to guarantee the stability of the glue output of the glue barrel and complete high-quality glue applying for loudspeaker products.

[0036] The present application adds a gas cylinder between the gas source and the glue applying device, which can buffer and stabilize the gas pressure of the gas source, and further adds a precision pressure reducing valve to the gas cylinder, which can stabilize the gas pressure entering the gas cylinder. The gas cylinder and the precision pressure reducing valve are connected in series in the gas circuit of the glue applying device, and cooperate to achieve two-stage pressure stabilizing, which can effectively improve the stability of the gas pressure acting on the glue barrel of the glue applying device. A second precision pressure reducing valve can be further added before the glue barrel of the glue applying device to realize three-stage pressure stabilizing and further improve the stability of the gas pressure.

[0037] From the above, the application can greatly improve the air pressure stability of the glue barrel of the glue dispensing equipment, precisely control the air pressure in a very small range, thereby ensuring the stability and consistency of the glue dispensing amount of the glue dispensing equipment, and improving the yield and efficiency of the loudspeaker glue dispensing operation.

[0038] The technical solutions of the application are described in detail above through specific examples. In the above examples, the description of each example has its own focus, and the parts not described in detail in a certain example can be referred to the related description of other examples.

[0039] It should be understood that the above examples are only used to illustrate the technical solutions of the application, rather than limit them. Those skilled in the art can modify the technical solutions described in the above examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and protection scope of the technical solutions of the examples of the application.
