[0041] When the surface of the thermal print head needs to be cleaned, the loading device 110 first loads the thermal print head to be cleaned to the cleaning device 130, and then the driving mechanism drives the sponge roller pair 132 and the brush roller pair 133 to rotate, the sponge roller pair 132 transports the thermal print head, and the brush roller pair 133 cleans the thermal print head transported by the sponge roller pair 132, and at the same time the water pipe 134 sprays cleaning water onto the sponge roller pair 132 and the brush roller pair 133, and the brush roller pair 133 uses the cleaning water to clean the thermal print head transported by the sponge roller pair 132, and the thermal print head after cleaning enters the conveying mechanism 142, and the conveying mechanism 142 conveys the thermal print head transported from the sponge roller pair 132, and the hair dryer mechanism blows air on the thermal print head transported by the conveying mechanism 142 to dry the thermal print head transported by the conveying mechanism 142, and finally the unloading mechanism 150 unloads the cleaned thermal print head. The thermal print head surface cleaning device 100 provided in the embodiment of the present invention can automatically clean and air-dry the surface of the thermal print head, thereby reducing the use of manpower and lowering labor costs.

[0042] The thermal print head surface cleaning device 100 provided by the present utility model embodiment, further, please refer to Figure 2 and Figure 3The drive mechanism includes a first drive assembly 135 and a second drive assembly 136.

The brush roller pair 133 rotates at a faster speed than the sponge roller pair 132.

In this embodiment, both the first drive assembly 135 and the second drive assembly 136 utilize drive motors. The drive motors are mounted outside the cleaning tank 131 and sequentially drive the sponge roller pair 132 and the brush roller pair 133 via belts.

[0043] The thermal print head surface cleaning device 100 provided by the embodiment of the present invention is further combined with Figure 4 and Figure 5 An adjustment base 143 is mounted on the support frame 141. The adjustment base 143 is provided with a central hole 144 and an arc-shaped hole 145. The blower mechanism includes the support frame 141 and an air knife 147. The air knife 147 is mounted on the support frame 141. The support frame 141 is provided with a rotating shaft and a locking member. The rotating shaft is rotatably mounted in the central hole 144. The locking member is used to lock the support frame 141 at any position in the arc-shaped hole 145 to adjust the blowing angle of the air knife 147. When it is necessary to adjust the blowing angle of the air knife 147 relative to the thermal print head, the support frame 141 is driven to rotate about the rotating shaft to adjust the blowing angle of the air knife 147 relative to the thermal print head. After the adjustment is in place, the locking member locks the support frame 141 at the corresponding position in the arc-shaped hole 145 to fix the blowing angle of the air knife 147 relative to the thermal print head.

[0044] In this embodiment, the wind knife 147 uses an anti-static wind knife 147, and uses clean compressed air to blow dry the water stains on the surface of the thermal print head. A positioning channel is provided on the support frame 141, and the positioning channel includes two vertically parallel limit plates 148 spaced apart. The conveying mechanism 142 can convey the thermal print head located between the two limit plates 148.

The loading mechanism 112 is used to grab the thermal print heads to be cleaned stored in the loading storage mechanism 111 and transfer them to the loading conveying mechanism 113. The loading conveying mechanism 113 is used to transfer the thermal print heads to be cleaned to the loading transfer mechanism 114. The loading transfer mechanism 114 is used to transfer the thermal print heads to be cleaned to the cleaning device 130. Similarly, the unloading device includes an unloading storage mechanism, an unloading mechanism 150, an unloading conveying mechanism, and an unloading transfer mechanism. The unloading transfer mechanism can transfer cleaned thermal print heads to the unloading conveying mechanism, and the unloading mechanism 150 can grab the thermal print heads on the unloading conveying mechanism and transfer them to the unloading storage mechanism.

[0046] For details, please refer to Figure 6 and Figure 7 The material loading and storage mechanism 111 includes a lifting assembly 115 and a material shuttle 116 mounted on the lifting assembly 115. The material shuttle 116 has stacked limit slots on opposite sides thereof. The ends of the thermal print head are correspondingly positioned in the limit slots on opposite sides of the material shuttle 116. The material loading mechanism 112 includes a mounting bracket 117, on which are mounted a transverse drive assembly 118 and a lifting rod 119.

The mounting bracket 117 is mounted on a vertical drive assembly 120, which is capable of driving the lifting rod 119 to move vertically.

[0047] When the thermal print head needs to be loaded, the horizontal drive component 118 first drives the lifting rod 119 to move horizontally and extend until the lifting rod 119 extends into the material shuttle 116, and then the vertical drive component 120 drives the lifting rod 119 to move vertically upward so that the lifting rod 119 can lift the thermal print head, and then the horizontal drive component 118 drives the lifting rod 119 to move horizontally and retract, and finally the vertical drive component 120 drives the lifting rod 119 to move vertically downward, placing the lifted thermal print head on the loading and conveying mechanism 113, and the loading and conveying mechanism 113 then conveys the thermal print head to the loading transfer mechanism 114, and then the lifting component 115 drives the material shuttle 116 to descend the height of one limit slot, so that the loading mechanism 112 can load the thermal print head in the next limit slot.

[0048] In this embodiment, multiple thermal print heads are placed side by side in each layer of limiting grooves, and since the lateral drive component 118 drives the lifting rod 119 to move horizontally and extend, the multiple thermal print heads in the same layer of limiting grooves can be placed on the loading and conveying mechanism 113. The loading and conveying mechanism 113 simultaneously conveys the multiple thermal print heads to the loading transfer mechanism 114, and since the cleaning device 130 can only clean one thermal print head at a time, the lateral adjustment mechanism 121 adjusts the lateral position of the loading transfer mechanism 114 relative to the cleaning device 130, and can convey the thermal print heads on the loading transfer mechanism 114 to the cleaning device 130 in turn for cleaning.
