Description

Technical field:

[0001] The utility model relates to the technical field of thermal print head manufacturing, in particular to a device for cleaning sheet materials such as ceramic substrates for thermal print heads, which can quickly remove residual liquid on the surface of the sheet materials, has high working efficiency, and is stable and reliable. Background technology:

[0002] At present, in some production processes that require the use of processing liquid to treat the surface of the product, the liquid is sprayed on the surface of the product through a spray device. Usually in this process, there will be a liquid collection tank under the product to collect the liquid sprayed on the surface of the product. When the product enters the next liquid treatment process, the liquid treated in the previous step remains on the surface of the product and will be brought into the subsequent liquid treatment process with the product. This will not only lead to an increase in the consumption of the spraying liquid, but also cause the liquid in the collection tank to be a mixture of multiple liquids, which cannot meet the requirements of recycling, thereby increasing costs.

[0003] The key component of the thermal print head is the heating substrate for the thermal print head. During the production process, this component needs to be etched on the surface to form an electrical circuit. The heating substrate is made of thin-film ceramic material with high surface flatness, smoothness and strong resistance to bumps. When cleaning the surface of this component, at least two cleaning liquids are required for cleaning, so the above-mentioned problems are faced. Summary of the invention:

[0004] In view of the shortcomings and deficiencies in the prior art, the utility model proposes a sheet material cleaning device which can clean sheet materials such as ceramic substrates for thermal print heads and can quickly remove residual liquid on the surface of sheet materials, has high working efficiency, and is stable and reliable.

[0005] The utility model achieves this through the following measures:

[0006] A flaky material cleaning device is provided with a frame, characterized in that a conveying component is provided on the frame, a processing liquid spraying mechanism is provided above the conveying component, the conveying component is provided with more than two electric rollers arranged at equal intervals along the material conveying direction; a surface residual liquid dumping component is also provided, the surface residual liquid dumping component includes a position sensor and a material horizontal posture adjustment component, the position sensor is arranged below the conveying component and in front of the material horizontal posture adjustment component, the material horizontal posture adjustment component is located between two adjacent electric rollers in the conveying component and on one side of the axis in the material conveying area, and the material horizontal posture adjustment component includes a lifting cylinder that rises / falls along the gap between two adjacent electric rollers.

[0007] The utility model is also provided with a control component, which includes a controller, a transmission control circuit, a position sensor and a lifting cylinder control circuit. The controller is respectively connected to the transmission control circuit, the position sensor and the lifting cylinder control circuit. The transmission control circuit is connected to the electric roller, and the lifting cylinder control circuit is connected to the lifting cylinder.

[0008] In order to improve the stability of adjusting the horizontal posture of the conveyed material, the utility model arranges two lifting components along the material conveying direction, the two lifting components are arranged on the same side of the axis in the material conveying area, are respectively located in the gaps between three adjacent electric rollers, and are both connected to the lifting cylinders, so as to tilt the sheet material located on the upper surface of the conveying component and complete the removal of residual liquid on the surface.

[0009] According to the spraying requirements, at least two groups of processing liquid spray mechanisms are arranged above the material conveying component of the utility model, and each group of processing liquid spray mechanisms includes a spray head and a spray pipeline connected to the spray head. At least two spray liquid collecting tanks corresponding to the two or more processing liquid spray mechanisms are arranged below the material conveying component for collecting excess spray liquid.

[0010] The surface of the electric roller of the utility model is provided with a polytetrafluoroethylene material coating, which is used as a handling fixture and can hold up the non-use surface of the ceramic substrate with a relatively small friction coefficient.

[0011] When the utility model is in use, a position sensor is used to detect that the ceramic substrate has reached a predetermined position before the material is transported out of the first collecting tank. A lifting cylinder will lift the side of the ceramic substrate at the lower part of the non-use surface of the ceramic substrate, so that the ceramic forms an inclined angle, which prompts the surface liquid to quickly peel off the surface of the substrate. Considering that if the substrate is in the process of being transported, the lifting of the cylinder will cause the substrate to be unstable, so when the substrate reaches a suitable position, the position sensor will be used to sense, the electric roller will stop running, the cylinder will be lifted, the material will be tilted, and the residual liquid on the surface will be removed.

[0012] Compared with the prior art, the utility model has the remarkable advantages of reasonable structure, stable operation, high working efficiency and the like. Description of the drawings:
