[0036] When the weight sensor 304 at the bottom of the glue storage bucket one 301 and the glue storage bucket two 303 detects that the weight in the bucket reaches the lower limit, the weight sensor 304 feeds back information to the control system 400, and the control system 400 issues a warning.

[0037] Specifically, the positioning mechanism body 200 further comprises a height measuring sensor 201, a positioning sensor 203 and a product positioning confirmation detection photoelectricity 202, the height measuring sensor 201 is used to measure the filling height of the glue mixing valve body 100 and feed back to the control system 400, so as to better ensure that the bottom of the glue mixing pipe 102 reaches the specified filling height, the positioning sensor 203 is used to detect whether the workpiece to be filled on the positioning mold 204 reaches the specified filling position, that is, whether the workpiece to be filled is installed in place, and the product positioning confirmation detection photoelectricity 202 is used to determine whether the glue outlet of the glue mixing pipe 102 reaches the specified filling position, through the setting of the product positioning confirmation detection photoelectricity 202, it is ensured that the workpiece to be filled is located at the bottom of the glue mixing pipe 102, and the bottom of the glue mixing pipe 102 can flow down along the wall, preventing air from being brought into the workpiece after the suspended glue enters the workpiece, and avoiding bubbles in the glue injection process.

[0038] Specifically, the glue mixing pipe 102 is a dynamic glue mixing pipe, which ensures that the glue is mixed again in the glue mixing pipe 102, i.e. the dynamic glue mixing pipe, after being mixed out of the input glue pipe 106 and the glue cavity 101.

[0039] Specifically, the glue mixing valve body 100 further comprises an adjusting valve 110, the adjusting valve 110 is used to adjust the pressure of the air inlet port 109, so as to better control the air pressure entering the air inlet port 109, when the glue enters the input glue pipe 106, the air pressure in the channels of the input glue pipe 106, the glue cavity 101 and the glue mixing pipe 102 is adjusted through the adjusting valve 110, so as to realize the adjustment of the glue filling pressure, so as to better perform the filling action.

[0045] The utility model discloses specific working principle:

[0046] Before starting the pouring, the control system 400 will be initialized, including checking the status of each component and other parameters, and ensuring that the supply of glue is sufficient. The workpiece to be poured is clamped and fixed in the positioning mold 204. When starting the pouring operation, the glue mixing pipe 102 is accurately moved to the specified pouring area under the driving of the positioning mechanism main body 200. The moving process is driven by a servo motor 206, the driving shaft 207 is responsible for power transmission, and the control XY axis 205 is used to realize accurate positioning.

[0047] The pouring height of the glue mixing valve main body 100 is measured by the height measuring sensor 201 and fed back to the control system 400, so as to better ensure that the bottom of the glue mixing pipe 102 is at the specified pouring height. The positioning sensor 203 detects whether the workpiece to be poured on the positioning mold 204 reaches the specified pouring position, that is, whether the workpiece to be poured is installed in place.

[0048] When the glue mixing pipe 102 reaches the specified area, the glue mixing valve main body 100 is driven by the Z-axis 208 to start moving downward and gradually approach the workpiece to be poured. The product positioning confirmation detection photoelectric sensor 202 determines whether the glue outlet of the glue mixing pipe 102 has reached the specified pouring position, so as to ensure that the workpiece to be poured is located at the bottom of the glue mixing pipe 102, and the bottom of the glue mixing pipe 102 can flow down and adhere to the wall, preventing the glue from hanging and affecting the quality of the subsequent pouring workpiece.

[0049] Then, according to the preset pouring speed, pouring amount and pressure, the glue valve 104 and the adjusting valve 110 are adjusted, the control system 400 starts the pouring action, and the glue is fully mixed and uniformly mixed in the input glue pipe 106, the glue cavity 101 and the glue mixing pipe 102, and then stably injected into the pouring target area.

[0050] After completing a single pouring, the glue mixing valve main body 100 is driven upward by the Z-axis 208 to move away from the current pouring position and move to the next specified pouring target area. After completing the stage pouring task, the control system 400 starts the self-cleaning function, that is, the air pressure input through the air inlet port 109 can preliminarily clean and empty the residual glue in the input glue pipe 106, the glue cavity 101 and the glue mixing pipe 102. Then, through the cleaning port 108, the cleaning solvent is injected, and the cleaning solvent passes through the input glue pipe 106, the glue cavity 101 and the glue mixing pipe 102 again, and then cooperates with the air pressure input through the air inlet port 109, that is, the air pressure pushes the cleaning solvent to effectively clean the position where the residual glue still flows, and finally is discharged into the residual glue collection container 210, so as to ensure that the glue pipeline is clean and unblocked during subsequent pouring.

[0051] The above merely is the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any modification and replacement based on the technical scheme and the application concept provided by the present application should be covered in the protection scope of the present application.
