Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0056] Example 1:

[0057] As Figure 1The utility model discloses a base station water tank 20 for a sweeping and mopping robot, which is formed by fusing an upper tank shell 201 and a lower tank shell 202 together.

[0058] Referring to Figure 2 , the water tank fusing device 10 comprises a workbench 1, a clamping mold 2, a blowing mechanism 3 and a high-frequency induction fusing device 4. The clamping mold 2 is used for clamping and fixing the upper tank shell 201 and the lower tank shell 202 to be fused, and comprises an upper mold 22 and a lower mold 21. The workbench 1 has a horizontal plate 11, the lower mold 21 is installed on the horizontal plate 11 and is used for placing the lower tank shell 202, the upper mold 22 is driven by a pressing mechanism and can move close to or away from the lower mold 21, and the lower mold 21 comprises a first accommodating cavity 211 which is opened towards the upper mold 22. The first accommodating cavity 211 is used for installing and accommodating the lower tank shell 202. The blowing mechanism 3 comprises an air outlet piece 31 and an air inlet piece 32 which are arranged at the bottom of the first accommodating cavity 211, and the high-frequency induction fusing device 4 comprises an induction coil 41.

[0059] On the basis of Figures 1-2 , referring to Figure 3 , the lower mold 21 further comprises an accommodating groove 212 which surrounds an outer side edge arranged above the first accommodating cavity 211, and the induction coil 41 is arranged in the accommodating groove 212. An inner edge of the first accommodating cavity 211 is provided with a receiving part 2111, the lower tank shell 202 has a lower fusing edge 2021 which is abutted and fixed in the receiving part 2111, and the upper tank shell 201 is clamped by the upper mold 22 and placed on the lower tank shell 202.

[0060] The bottom of the lower tank shell 202 is provided with a water outlet hole 2022 and a water inlet hole 2023 which are matched with the air outlet piece 31 and the air inlet piece 32, and when the lower tank shell 202 is pushed into the first accommodating cavity 211, the air outlet piece 31 and the air inlet piece 32 can be tightly inserted into the water outlet hole 2022 and the water inlet hole 2023 respectively.

[0061] In actual production, as shown in the enlarged view in Figure 1 , in order to make the upper tank shell 201 and the lower tank shell 202 be fused normally, the upper tank shell 201 is provided with an upper fusing edge 2011 which is matched with the lower fusing edge 2021 on the side opposite to the lower fusing edge 2021. A metal coil 203 for assisting high-frequency heating is arranged between the upper fusing edge 2011 and the lower fusing edge 2021. An insert 204 is arranged around the edge of the upper fusing edge 2011, and a slot 205 which is matched with the insert 204 is arranged on the lower fusing edge 2021.

[0062] On the basis of Figures 1-3 , referring to Figures 4-5. Before welding, the lower box shell 202 with the water outlet hole 2022 and the water inlet hole 2023 is placed into the first accommodating cavity 211, the air outlet member 31 and the air inlet member 32 are respectively inserted into the water outlet hole 2022 and the water inlet hole 2023, and the pre-positioning is realized. The metal coil 203 is placed into the slot 205, and the upper box shell 22 is inserted into the slot 205 through the plug-in part 204. In some embodiments, the bottom of the slot 205 and the end of the plug-in part 204 are provided with a cavity (not labeled in the figure) for positioning the metal coil 203. When the plug-in part 204 is inserted into the slot 205, the metal coil 203 is limited in the cavity, and the welding effect can be expected.

[0063] In other embodiments, the lower box shell 202, the metal coil 203 and the upper box shell 201 can be pre-assembled and then placed into the first accommodating cavity 211. The specific implementation is adjusted according to the beat and process of the production line, which is not described here.

[0064] After the pre-assembled lower box shell 202, the metal coil 203 and the upper box shell 201 are sequentially installed and placed into the first accommodating cavity 211, the upper mold 22 moves towards the lower mold 21 and presses the upper box shell 201, so that the plug-in part 204, the metal coil 203 and the slot 205 are pressed together.

[0065] Specifically, continuing to refer to Figures 2-5 The upper mold 22 includes a second accommodating cavity 221 on the side facing the lower mold 21, and the inner side of the second accommodating cavity 221 has a pressing part 2211. When the upper mold 22 moves towards the lower mold 21, the upper box shell 201 enters the second accommodating cavity 221, and the pressing part 2211 abuts and presses the upper welding edge 2011. With the pressing of the upper box shell 201, the lower welding edge 2021 also continues to move towards the first accommodating cavity 211 and is sunk into the receiving part 2111, realizing accurate positioning, and also making the force on the upper box shell 201 more reasonable.

[0066] When the current welding along 2021 sinks into the receiving part 2111, the high-frequency induction heater 4 is started, and the induction coil 41 is heated by high-frequency current, so that the metal coil 203 in the induction coil 41 is heated by high frequency. In order to achieve the highest heating efficiency, the metal coil 203 should be located in the area close to the induction coil position before being heated by high frequency. Because of the high heating efficiency of high frequency, the plug-in part 204 and the plug-in groove 205 in contact with the metal coil 203 are instantaneously melted by high temperature, and the upper mold 22 will continue to move downward to the lower mold 21. Under the pressure of the upper mold 22, the high-temperature melted part of the plug-in part 204 and the plug-in groove 205 is high, and finally realizes the connection of the upper box shell 201 and the lower box shell 202. Compared with the ultrasonic welding process, high frequency induction has higher power and generates more heat in an instant, so that more plastic material is melted by heat in a very short time, and the combination is more firm and the bearing capacity is stronger. Compared with the traditional hot pressing method, its efficiency and welding effect are more excellent.

[0067] In Figures 1-5 the premise, refer to Figure 6 In some embodiments, the workbench 1 further comprises a vertical plate 12 vertically arranged on one side of the horizontal plate 11, and the high-frequency induction heater 4 comprises an interface 42 and a high-frequency generator 43, the interface 42 is fixed to the side of the vertical plate 12 facing the clamping mold 2, and the induction coil 41 is electrically connected to the high-frequency generator 43 through the interface 42.

[0068] More specifically, the lower mold 21 on the side facing the vertical plate 12 is provided with a communication port 213 communicating with the accommodating groove 212, and the induction coil 41 has a connecting part 411 penetrating the communication port 213 and connected with the interface 42. Through the above arrangement, the induction coil 41 is more simple and convenient to electrically connect with the high-frequency generator 43, and it is easy to maintain and replace the lower mold 21 with the induction coil 41.

[0069] In further embodiments, the air inlet member 32 is provided with a sealing member 321 around the side facing the first accommodating cavity 211, and the air inlet member 32 is provided with an air inlet port 322 at the end facing the first accommodating cavity 211, and the air inlet member 32 inputs high-pressure gas into the first accommodating cavity 211 through the air inlet port 322. Similarly, the air outlet member 31 is also provided with a sealing member 321 around the side facing the first accommodating cavity 211, and the air outlet member 31 is provided with an air outlet port 311 at the end facing the first accommodating cavity 211, and the air outlet member 31 can control the communication between the air outlet port 311 and the outside.

[0070] Through the sealing member 321, the air outlet member 31 and the air inlet member 32 are respectively inserted into the water outlet hole 2022 and the water inlet hole 2023 of the base station water tank 20, and have good sealing effect at the position of mutual contact, and are controlled through the air inlet port 322 and the air outlet port 311, so that the air inlet member 32 and the air outlet member 31 realize the functions of cooling, air tightness detection and discharging of the base station water tank 20 after the welding is completed.

[0071] As shown in Figure 7 , at the same time of starting the induction coil 41, the air inlet member 32 inserted into the lower tank shell 202 fills high-pressure air into the lower tank shell 202. The air inlet member 32 can be connected with the air source system outside. The air outlet member 31 is in communication with the outside air, and the filled air takes away the heat generated by the metal coil 203 after filling the inside of the base station water tank 20, so as to realize the cooling function.

[0072] After the welding is completed, as shown in Figure 8 , the air outlet member 31 is disconnected with the outside air, and the upper die 22 is paused after moving a certain distance, and the welded base station water tank 20 is pushed away from the first containing cavity 211 and abuts against the upper die 22 due to the pressure difference between the inside and outside. At this time, the air inlet member 32 stops filling high-pressure gas, and detects whether the air pressure inside the base station water tank 20 continuously decreases, so as to judge whether the welded base station water tank 20 meets the air tightness requirement.

[0073] After the air tightness is detected, the upper die 22 continues to move upwards, the air inlet member 32 continues to fill high-pressure gas into the inside of the base station water tank 20 through the air inlet port 322, until the air inlet member 32 and the air outlet member 31 are completely separated from the water inlet hole 2023 and the water outlet hole 2022. At this time, the base station water tank 20 can be moved out by manpower or loading and unloading equipment, and the welding work of the next base station water tank 20 can be continued.

[0074] In addition, considering the actual processing and use requirements, as shown in Figure 3 and Figure 5 , the filling member 2121 is arranged in the containing groove 212, the filling member 2121 covers the containing groove 212 and is flush with the end face of the containing groove 212. The main purpose of arranging the filling member 2121 is to provide protective wrapping for the induction coil 41 arranged in the containing groove 212, so as to avoid corrosion of the induction coil 41 caused by humid environment and oil stains. In this embodiment, the filling member 2121 is photosensitive resin. In other embodiments, a solidifiable liquid sealant can be used to realize sealing.

[0075] In summary, the water tank welding device provided by the utility model, through setting the induction coil of the high-frequency induction welding device on the lower mold, driving the upper mold to press the upper tank shell, cooperating with the plug-in structure and the metal coil arranged on the upper tank shell and the lower tank shell, the upper tank shell and the lower tank shell are efficiently and firmly welded together through high-frequency heating. Compared with ultrasonic welding, the welding range is larger, and the connection is more fully fused.

[0076] Secondly, after the air outlet and the air inlet are inserted into the water outlet hole and the water inlet hole of the base station water tank, the air inlet can be used to fill the high-pressure cooling gas into the water tank, the air outlet can be used to control whether the air outlet is connected with the outside world, and the pressing of the upper mold can be controlled, so that the functions of cooling, air tightness detection and discharging of the water tank after welding are realized.

[0077] In addition, the air outlet and the air inlet are arranged on the bottom of the first accommodating cavity, so that the lower tank shell can be quickly positioned through the corresponding water outlet hole and water inlet hole, and the feeding efficiency is improved.
