The filter cartridge guides the intercepted waste to the waste outlet. A cleaning assembly is installed on the top side of the filter cartridge to clean impurities adhering to the inner periphery of the filter cartridge; The two ball valves are connected by a transmission assembly to switch the flow path of the electroplating liquid heating cycle. The transmission assembly is triggered by the engagement of a rack. The rack is slidably connected to the rear side of the slide rail and is connected to the baffle plate through a traction assembly.

[0016] Working principle: First, fill a sufficient amount of plating liquid into the electroplating tank, then start the delivery pump, use the suction of the delivery pump to draw the plating liquid inside the electroplating tank into the branch pipe, and then enter the shell along the branch pipe. The flowing plating liquid is heated by the electric heating tube, so that the plating liquid returns to the electroplating tank again, and the cycle is repeated until the plating liquid is heated to a suitable temperature, and the electroplating operation of the plated parts begins. During the electroplating process, the impurities and waste generated by the reaction between the plated parts and the plating liquid will sink to the bottom of the electroplating tank, and with the suction of the delivery pump, it will be drawn into the inside of the branch pipe. When passing through the filter cartridge inside the branch pipe, the impurities and waste materials mixed in the electroplating solution are intercepted by the filter cartridge, sink to the bottom of the filter cartridge and the waste outlet at the bottom of the branch pipe, and the remaining electroplating solution passes through the inside of the shell again to be heated at a constant temperature and return to the inside of the electroplating tank.

When the flow path changes, the gear adjacent to rack 2 rotates, causing the meshing rack 2 to move downward, causing rack 2 to slide on the sliding rack, and driving the connecting rack connected thereto to press down the compressed airbag, so that the air inside the compressed airbag is input into the interior of the jet head and ejected from the jet port of the jet head, causing the airflow to impact the inner surface of the filter cartridge, causing the impurity mixture remaining on the filter cartridge to detach from the filter cartridge and fall into the waste outlet. After rack 2 is reset, the compressed airbag will stretch and expand under the lifting of the connecting rack to perform air extraction.

[0017] The present application provides a heating device based on the electroplating liquid in the electroplating tank. It has the following beneficial effects: 1. The present application adopts a separate design of the heating structure and the electroplating pool, which can avoid the situation where the impurities generated by electroplating during the electroplating process sink to the bottom and cover the heating structure when the traditional heating structure is located at the bottom of the electroplating pool. This enables the heating structure to stably heat the plating solution and reduce external influences. It is also more convenient to maintain the heating structure.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Example: The present application provides a heating device based on a plating solution in a plating tank, comprising: Please refer to the attached Figure 1 , Attachment Figure 2 and attached Fig.10 The electroplating pool 1 is used to contain the plating liquid for electroplating. The right side of the electroplating pool 1 is connected to a delivery pump 4 through a pipeline, and the left side of the electroplating pool 1 is connected to a heating chamber for heating the plating liquid through a pipeline, wherein the heating chamber is composed of a shell 3 fixedly connected to the left end of the rear side of the plate rack 2 and an electric heating tube 23 installed inside the shell 3, and the electric heating tube 23 is spirally shaped to expand the contact area. A guide slope is provided on the bottom side of the inner wall of the electroplating pool 1, so that when the electroplating reaction is carried out, the impurity waste generated by the electroplating reaction can be concentrated along the guide slope, and under the suction of the delivery pump 4, the plating liquid entering along the output port of the electroplating pool 1 is added to the circulation and separated from the inside of the electroplating pool 1.

[0024] Specifically, the separation design of the heating structure and the electroplating tank 1 can avoid the situation that when the conventional heating structure is located at the bottom of the electroplating tank 1, the impurities generated by electroplating sink to the bottom and cover the heating structure, reducing the heat transfer effect of the heating structure, thereby ensuring that the heating structure can stably heat the electroplating solution and reduce the influence of the outside. At the same time, it is more convenient to maintain the heating structure. The non-integrated structure can be maintained and replaced when any one of the electroplating tank 1 or the heating structure has problems, so as to reduce the maintenance difficulty. A sufficient amount of electroplating solution is poured into the electroplating tank 1, and then the delivery pump 4 is started. The electroplating solution in the electroplating tank is pumped into the branch pipe 5 by the suction of the delivery pump 4. The flowing electroplating solution is heated by the electric heating tube 23 in the shell 3 that enters the branch pipe 5, and the electroplating solution returns to the electroplating tank 1 again. The cycle is repeated until the electroplating solution is heated to a suitable temperature, and the electroplating operation of the plated part is started. During the electroplating process, the impurity waste generated by the reaction between the plated part and the electroplating solution will sink to the bottom of the inner part of the electroplating tank 1.

[0025] Please refer to the attached Figure 1 , Attachment Figure 3 and attached Figure 4, the plate rack 2 is fixedly connected to the rear side of the electroplating pool 1, the branch pipe 5 is fixedly connected to the top end of the rear side of the plate rack 2, the slide rail 8 is fixedly connected to the middle end of the rear side of the plate rack 2, the bottom end of the rear side of the plate rack 2 is connected to the baffle plate 10 through the electric guide rail 9, the top side and the left side of the branch pipe 5 are provided with output ends, and are connected to ball valves, the output end of one of the ball valves is connected to the left side of the input end of the heating chamber, and the output end of the other ball valve is connected to the top side of the input end of the heating chamber through the converter tube 22.

[0026] Please refer to the attached Figure 6 and attached Figure 7 The ball valve is composed of a valve body 6 and a valve ball 7 which is rotatably connected to the inside. The two valve bodies 6 are fixedly connected to the two output ends of the branch pipe 5 respectively. The rear side of the valve ball 7 passes through the rear side of the outer wall of the valve body 6. The bottom side of the branch pipe 5 is provided with a waste outlet for discharging impurity waste generated in the electroplating reaction. The waste intercepted by the filter cartridge 16 will be guided to the waste outlet. The waste outlet is located on the top side of the baffle 10. The input end of the branch pipe 5 is connected to the delivery pump 4 through a pipeline to form a flow path for the heating circulation of the electroplating solution. The delivery pump 4 serves as a power source for the flow path of the electroplating solution.

[0027] Please refer to the attached Figure 7 -Attached Fig. 9 , filter cartridge 16, filter cartridge 16 is fixedly connected to the inside of branch pipe 5, and filter cartridge 16 is located on the top side of the waste outlet, and an opening is provided on the top side of filter cartridge 16 near the input end of branch pipe 5, so that when the plating liquid circulates, it enters the inside of filter cartridge 16 through the opening and is filtered by filter cartridge 16, and impurities and wastes remain in the inside of filter cartridge 16, and the bottom output port of nozzle head 17 fixedly connected to the top side of the middle end of branch pipe 5 is located in the inside of filter cartridge 16, and the top side input end of nozzle head 17 is connected to nozzle head 17 through a pipeline, and nozzle head 17 is fixedly connected On the top side of the plate frame 2, impurities adhering to the inner periphery of the filter cartridge 16 are cleaned, wherein the nozzle structure of the nozzle 17 is of a type with a smaller aperture, so that after the gas is injected, the airflow can be ejected at high pressure, and a sliding frame 19 is fixedly connected to the right end of the top side of the plate frame 2, and a rack 20 is vertically slid on the left side of the sliding frame 19, and the left side of the rack 20 is meshed with one of the gears 14, and the rear side of the sliding frame 19 is fixedly connected to the top side of the compressed air bag 18 through a connecting frame 21, so that the compressed air bag 18 can be stretched and compressed when the rack 20 moves vertically up and down.

[0028] Specifically, the structures such as the ball valve, branch pipe 5, and converter pipe 22 that are in direct contact with the plating solution have been treated with anti-corrosion to prevent the plating solution from corroding these structures, and insulation structures are set in these structures through which the plating solution flows, such as using rock wool, glass wool and other insulation materials for outer surface filling to ensure that the heat in the heating chamber can be transferred to the plating solution to the maximum extent, reduce energy consumption, and also help maintain the temperature stability of the plating solution during the transportation process. With the suction of the delivery pump 4, the plating solution is drawn into the interior of the branch pipe 5, passing through the filter cylinder 16 inside the branch pipe 5. The impurities and waste mixed in the plating solution are intercepted by the filter cylinder 16, sink to the bottom of the filter cylinder 16 and the waste outlet at the bottom of the branch pipe 5, and the remaining plating solution passes through the interior of the shell 3 again for constant temperature heating and returns to the interior of the electroplating tank 1. When the flow path changes, the gear 14 adjacent to the rack 20 rotates, causing the meshing rack 20 to move downward, causing the rack 20 to slide on the sliding frame 19, and driving the connecting frame 21 connected thereto to press down the compressed airbag 18, so that the air inside the compressed airbag 18 is input into the interior of the nozzle 17 and ejected from the nozzle of the nozzle 17, so that the airflow impacts the inner surface of the filter cartridge 16, causing the impurity mixture remaining on the filter cartridge 16 to detach from the filter cartridge 16 and fall into the waste outlet. After the rack 20 is reset, the compressed airbag 18 will stretch and expand while being lifted by the connecting frame 21 to evacuate air. Since some insoluble by-products are produced during the electroplating reaction, these by-products will also settle in the electroplating solution. For example, in the electroplating tin process, the Sn in the plating solution 2+ Oxidized to Sn by dissolved O2 4+ , and Sn 4+ The hydrolysis products are insoluble in sulfuric acid and have colloidal properties, which causes the plating solution to be turbid. When these colloidal impurities pass through the filter cartridge 16, they will adhere to the filter structure and are not easy to remove. Therefore, the impurities are flushed away by the jet gas to achieve an impact effect.

[0029] Please refer to the attached Figure 5 and attached Figure 6 A gear 14 is fixedly connected to the front side of two sprockets 15 connected by a chain belt, and the front side of the gear 14 is fixedly connected to the rear side of the valve ball 7. A rack 11 located at the bottom side of the other gear 14 is slidably connected to the rear side of the slide rail 8 to switch the flow path of the electroplating solution heating circulation. The two connecting columns 12 fixedly connected to the rear sides of the baffle plate 10 and the rack 11 are respectively connected by a traction rope. A pulley 13 is provided at the right end of the side close to the baffle plate 10 and the rack 11. The pulley 13 is rotatably connected to the rear side of the plate frame 2. Both ends of the traction rope are sleeved on the outer wall of the connecting column 12, and the middle end is in rolling contact with the outer periphery of the pulley 13. The left side of the rack 11 is connected to the left end of the slide rail 8 through a tension spring, and the tension spring is in a stretched state under normal conditions.

[0030] Specifically, when the waste in the waste outlet accumulates to a certain amount, the electric guide rail 9 is started to drive the shielding plate 10 to move, so that the through hole on the shielding plate 10 coincides with the opening at the bottom side of the waste outlet, so that the impurities and waste accumulated at the waste outlet are discharged. When the shielding plate 10 is displaced, the position of the traction rope on the connecting column 12 connected to the threshold value will change, so that the connecting column 12 connected to the rack 11 at the other end of the traction rope is no longer restrained by the traction rope, so that the rack 11 slowly moves to the left under the action of the stretched tension spring, and meshes with the gear 14 adjacent to the rack 11, so that the valve ball 7 connected to the gear 14 rotates, cutting off The circulation flow path of the plating liquid is cut off. Since the displacement of the baffle plate 10 is relatively slow, the rate at which the stretched tension spring pulls the rack 11 is also relatively uniform and slow, preventing the tension spring from resetting too quickly, causing the rack 11 to bounce and slide back and forth when resetting. The gear 14 drives another gear 14 through the sprocket 15 and the chain belt, so that the gear 14 drives the valve ball 7 connected to it to rotate, opening the flow path, allowing the plating liquid to flow to the exchange tube 22 and then enter the shell 3, and suspending the filtering work. During the switching of the flow path, the through hole on the baffle plate 10 has not yet overlapped with the waste outlet to reduce the loss of the plating liquid, and the baffle plate is immediately reset and closed after the waste is discharged from the waste outlet.

[0031] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
