[0024] Embodiment 1:

[0025] Please refer to Figures 1 to 5 , a feeding device for thin - sheet insert injection molding of the present invention, includes a workbench 1, and a driving part 2 is bolt - installed on the left side of the workbench 1 through a support rod.

[0026] There is a discharging device 3 arranged on the top of the workbench 1, and a material taking device 4 is arranged on the right side of the driving part 2. The discharging device 3 includes a loading bin 31 bolted to the rear end of the top of the workbench 1. The loading bin 31 provides a platform for installing other components. At the bottom end of the front end face of the loading bin 31, a blanking frame 32 is fixed by screws. At the upper end of the rear end face of the loading bin 31, a fixing plate 33 is fixed. A buzzer 34 is bolted to the top of the fixing plate 33. When the photoelectric sensor 36 does not detect a change in distance for a long time, the control terminal controls the buzzer 34 to start sounding an alarm, and the worker hears the signal to add the thin sheet inserts.

[0027] At the bottom end of the rear end face of the loading bin 31, an electric push rod 35 is bolted. At the lower end of the front end face of the blanking frame 32, a photoelectric sensor 36 is arranged. The front end telescopic rod of the electric push rod 35 is inserted and installed with a top plate 37. The electric push rod 35 drives the top plate 37 to push out the thin sheet inserts at the bottom. A rubber sleeve is adhesively installed on the outer side of the top plate 37 to prevent the thin sheet inserts from being damaged due to extrusion by the top plate 37. A wear-resistant layer is coated on the inner side of the blanking frame 32 to effectively reduce the wear generated when the blanking frame 32 comes into frequent contact with the thin sheet inserts.

[0028] The working principle of a feeding device for thin sheet insert injection molding based on Embodiment 1 is as follows:

[0029] First, when using this equipment, first place this equipment in the working area, and then connect the device to an external power supply to provide the power required for the operation of this equipment.

[0030] Second, when handling the thin sheet inserts for feeding in the injection molding work, the thin sheet inserts are likely to stack and adhere, which is not convenient for feeding. Therefore, during the work, the worker places the thin sheet inserts in the loading bin 31.

[0031] Third, when the thin sheet inserts drop to the bottom inside the loading bin 31, the photoelectric sensor 36 emits a light beam and detects a change in distance. At this time, the control terminal controls the electric push rod 35 to start, and the electric push rod 35 drives the top plate 37 to push out the thin sheet inserts at the bottom.

[0032] Fourth, at this time, the stacked and adhered thin sheet inserts are separated by the limit. After reaching the appropriate distance, the electric push rod 35 automatically resets. And when the photoelectric sensor 36 does not detect a change in distance for a long time, the control terminal controls the buzzer 34 to start sounding an alarm.

[0033] Fifth, the worker hears the signal to add the thin sheet inserts. In this way, it is convenient to quickly feed the thin sheet inserts, and the stacked and adhered thin sheet inserts can be separated by the limit. The position and distance of the thin sheet inserts are detected by the photoelectric sensor 36, which is convenient for monitoring the material inventory and alarming, and effectively improves the working efficiency of the overall injection molding work.

A vacuum pump 42 is bolted to the top of the square pipe 41, and the right port of the vacuum pump 42 is connected to the top pipe of the square pipe 41 through a conduit. The square pipe 41 provides a platform for installing other components. A connection bin 43 is provided at the bottom of the square pipe 41, and a vacuum chuck 44 is installed at the bottom of the connection bin 43 through a pipe with an opening at the bottom;

[0036] A pressure filter sleeve 45 is sleeved and installed at the inner bottom of the square pipe 41. The pressure filter sleeve 45 filters impurities in the air to avoid blocking the pipeline. A resistance heating plate 46 is fixedly connected to the inner top of the square pipe 41. A temperature sensor 47 is bolted to the rear end face of the square pipe 41. A digital temperature and humidity sensor is provided at the middle of the rear end face of the square pipe 41. The digital temperature and humidity sensor can detect the temperature and humidity of the outside world.

[0037] In this embodiment:

[0038] First, when the surrounding environment is relatively humid, water droplets are likely to condense on the surface of the thin sheet insert, which will affect the handling effect of the device on the thin sheet insert. When working, the control terminal controls the driving member 2 to start;

[0039] Second, the driving member 2 drives the square pipe 41 and the vacuum chuck 44 to move into the blanking frame 32. The set digital temperature and humidity sensor will detect the surrounding environment. When the environment is relatively humid, the control terminal controls the resistance heating plate 46 and the vacuum pump 42 to start;

[0040] Third, then the air flow pumped by the vacuum pump 42 is ejected after being heated by the resistance heating plate 46. The set temperature sensor 47 monitors and adjusts the heating temperature, and the hot air flow dries the thin sheet insert;

[0041] Fourth, then the control terminal controls the vacuum chuck 44 to be attached to the thin sheet insert and evacuates, and the pressure filter sleeve 45 filters the air;

[0042] Fifth, at this time, the thin sheet insert is negatively adsorbed and automatically transported and placed. This is convenient for drying the water droplets on the surface of the thin sheet insert with hot air flow, preventing the water droplets from affecting the negative adsorption effect, and detecting the temperature and humidity through the sensor to improve the intelligence of the device, effectively enhancing the handling efficiency of the thin sheet insert.

[0043] The utility model provides a feeding device for injection molding of thin sheet inserts through improvement. A discharging device 3 is arranged on the top of a workbench 1.

A photoelectric sensor 36 is used to detect the position and distance of the thin sheet inserts, which is convenient for monitoring and alarming the material inventory, effectively improving the working efficiency of the overall injection molding work. A material taking device 4 is arranged on the right side of a driving part 2. The water droplets on the surface of the thin sheet inserts can be dried by a resistance heating plate 46 and a temperature sensor 47, which is convenient for drying the water droplets on the surface of the thin sheet inserts with hot air flow, preventing the water droplets from affecting the negative pressure adsorption effect, and detecting the temperature and humidity through a sensor to improve the intelligence of the device, effectively enhancing the handling efficiency of the thin sheet inserts.
