Description

Technical Field

[0001] The utility model relates to the technical field related to battery production, in particular to a lead-acid battery liquid injection device. Background Art

[0002] Lead-acid batteries are now widely used in automobiles, trams, machinery and other fields due to their stable voltage and low price. The electrodes of lead-acid batteries are mainly made of lead and its oxides, and its electrolyte is sulfuric acid solution. In the production process of lead-acid batteries, the injection of electrolyte into the lead-acid battery is a very important process.

[0003] The filling of lead-acid batteries mainly involves injecting a certain amount of electrolyte into the battery filling port. The existing filling devices for lead-acid battery production lack effective measures to fix the batteries. During the filling process, due to the impact of the electrolyte, the battery is prone to shaking or position shifting, causing leakage, affecting the filling quality and filling efficiency, and also causing waste of resources and environmental pollution. Utility Model Content

[0004] The utility model aims to provide a lead-acid battery filling device, which can solve the problem that shaking or position deviation occurs during battery filling, resulting in leakage and affecting the working efficiency of filling.

[0005] To this end, the technical solution adopted by the utility model is: a lead-acid battery filling device, including a base, a conveyor belt for conveying batteries and a fixing assembly for fixing the batteries arranged on one side of the conveyor belt, the fixing assembly including a motor and a cam arranged at the output end of the motor, a connecting plate is arranged on the side of the cam away from the conveyor belt, one end of the connecting plate is hinged on the base, and a "C"-shaped card frame is arranged on the other end, the opening of the "C"-shaped card frame faces the direction of the conveyor belt, the opening size of the "C"-shaped card frame matches the size of the corresponding battery, the "C"-shaped card frame can be extended into the conveyor belt to fix the battery, a fixing plate is arranged on the side of the base close to the "C"-shaped card frame, a reset spring is connected between the fixing plate and the connecting plate, and a filling assembly is arranged above the base.

[0006] Further preferably, the injection assembly includes a support plate, the support plate is supported above the base by a fixing column, a liquid injection box is arranged on the support plate, and two liquid injection pipes are arranged below the liquid injection box. The liquid injection box is fixed on the support plate above the base to facilitate liquid injection of the battery and improve work efficiency.

[0007] More preferably, a liquid level detector is provided at the lower end of the injection pipe. The liquid level detector below the injection pipe detects the electrolyte capacity in the battery, and the injection can be stopped at any time to ensure that the electrolyte does not overflow during injection.

[0008] More preferably, an electronic valve is provided on the liquid injection tube, and the liquid injection of the liquid injection tube can be controlled by the electronic valve, which is more convenient.

[0009] Further preferably, protective plates are provided on both sides of the conveyor belt, and the height of the "C"-shaped card frame is higher than the protective plates. Protective plates are provided on both sides of the conveyor belt to fix the directions of both sides of the battery and ensure stability during injection.

[0010] The beneficial effects of the utility model are as follows: the battery is fixed by the "C"-shaped clamp frame, and after the liquid injection is completed, the motor drives the cam to rotate, and when the cam rotates to one side of the fixed plate, it will drive the fixed plate to rotate clockwise around the hinge seat at the left end, so that the fixed plate drives the "C"-shaped clamp frame away from the conveyor belt, thereby releasing the battery that has been filled with liquid; when the cam continues to rotate and leaves the side close to the fixed plate, the return spring pulls the fixed plate back to its original position, and the "C"-shaped clamp frame fixes the next battery to be filled with liquid. At this time, the liquid injection component injects liquid into the battery, which can avoid the battery from shaking or the position of the battery from shifting during the battery injection, resulting in electrolyte leakage, thereby improving the battery injection efficiency.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figure 1-2 As shown, a lead-acid battery injection device comprises a base 1, on which a conveyor belt 2 for conveying batteries and a fixing assembly for fixing the batteries arranged on one side of the conveyor belt 2 are arranged, the fixing assembly comprises a motor 3 and a cam 4 arranged at the output end of the motor 3, a connecting plate 5 is arranged on the side of the cam 4 away from the conveyor belt 2, one end of the connecting plate 5 is hinged on the base 1, and a "C"-shaped card frame 6 is arranged on the other end, the opening of the "C"-shaped card frame 6 faces the conveyor belt 2, the opening size of the "C"-shaped card frame 6 matches the size of the corresponding battery, the "C"-shaped card frame 6 can be extended into the conveyor belt 2 to fix the battery, a fixing plate 7 is arranged on the side of the base 1 close to the "C"-shaped card frame 6, a reset spring 8 is connected between the fixing plate 7 and the connecting plate 5, and a injection assembly is arranged above the base 1.

[0015] The liquid injection assembly includes a support plate 10, which is supported above the base 1 by a fixing column 9, and a liquid injection box 11 is arranged on the support plate 10, and two liquid injection pipes 12 are arranged below the liquid injection box 11. The liquid injection box 11 is fixed on the support plate 10 above the base 1, which facilitates the liquid injection of the battery and improves the work efficiency.

[0016] The lower end of the injection pipe 12 is provided with a liquid level detector 13. The liquid level detector 13 below the injection pipe 12 detects the electrolyte capacity in the storage battery, and the injection can be stopped at any time to ensure that the electrolyte does not overflow during the injection.

[0017] An electronic valve is provided on the liquid injection pipe 12. It is more convenient to control the liquid injection of the liquid injection pipe 12 by the electronic valve.

[0018] Protection plates 14 are provided on both sides of the conveyor belt 2, and the height of the "C"-shaped card frame 6 is higher than the protection plates 14. Protection plates 14 are provided on both sides of the conveyor belt 2 to fix the directions of both sides of the battery and ensure stability during injection.

[0019] The battery is fixed by the "C"-shaped clamp frame 6. After the injection is completed, the motor 3 drives the cam 4 to rotate. When the cam 4 rotates to one side of the fixed plate 7, it will drive the fixed plate 7 to rotate clockwise around the hinge seat at the left end, so that the fixed plate 7 drives the "C"-shaped clamp frame 6 away from the conveyor belt 2, thereby releasing the battery that has been injected with liquid; when the cam 4 continues to rotate and leaves the side close to the fixed plate 7, the return spring 8 pulls the fixed plate 7 back to its original position, and the "C"-shaped clamp frame 6 fixes the next battery to be injected with liquid. At this time, the injection assembly injects liquid into the battery, which can avoid the battery from shaking or the position of the battery from shifting during the injection, resulting in electrolyte leakage, thereby improving the injection efficiency of the battery.
