DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figures 1 to 17 As shown, the valve-controlled automatic lead-acid battery acid-adding system of the present invention comprises a conveying mechanism 1 and an acid-injecting mechanism 2. The conveying mechanism 1 is used to transfer the battery 3 that needs acid-adding and the battery 3 that has been filled with acid. The acid-injecting mechanism 2 is located at the upper end of the conveying mechanism 1. When the conveying mechanism 1 transports the battery 3 that needs acid-adding to the lower end of the acid-injecting mechanism 2, the acid-injecting head 5 located in the acid-injecting mechanism 2 can be pushed to shift position by the injection head 4 on the battery 3 under the power of the conveying mechanism 1, so that the acid-injecting head 5 is opened, and the acid liquid flowing out of the acid-injecting head 5 will enter the battery 3 from the injection head 4.

[0021] In view of the needs in the actual production process, multiple transmission mechanisms 1 and multiple acid injection heads 5 coordinated with the transmission mechanisms 1 can be provided, so that the acid injection efficiency of the storage battery 3 can be improved, production can be accelerated, and market demand can be met. In addition, improvements can be made for storage batteries 3 of different models, and the number of acid injection heads 5 on a sealing member 17 can be increased, so that it is convenient to uniformly inject acid into a single acid tank, so that the acid liquids in different acid tanks in the same storage battery 3 are the same, and the acid injection efficiency can be effectively improved and the service life of the storage battery 3 can be increased.

[0022] The conveying mechanism 1 is provided with multiple groups, which can be arranged and controlled according to actual production requirements. The conveying mechanism 1 is provided with a first conveyor belt 6 and a second conveyor belt 7, the first conveyor belt 6 is located at the lower end of the acid injection head 5, and the second conveyor belt 7 is located next to the first conveyor belt 6, and there is a gap between the first conveyor belt 6 and the second conveyor belt 7, and the distance of the gap cannot exceed one-third of the width of the battery 3, so as to facilitate the transfer of the battery 3 from the first conveyor belt 6 to the second conveyor belt 7.

[0023] The first conveyor belt 6 and the second conveyor belt 7 are located at the same height, or the second conveyor belt 7 may be located slightly lower than the first conveyor belt 6, so that the batteries 3 on the first conveyor belt 6 can be easily transferred to the second conveyor belt 7. The first conveyor belt 6 transports the batteries 3 that need to be acid-added to a designated location, and the second conveyor belt 7 transfers the batteries 3 that have been acid-added on the first conveyor belt 6. The transmission directions of the first conveyor belt 6 and the second conveyor belt 7 are opposite.

[0024] A fixed plate 8 is also provided in the conveying mechanism 1, on which a symmetrically arranged push plate 9 is provided, and the push plate 9 is located above the first conveyor belt 6. A fixed area is formed in the middle of the symmetrically arranged push plates 9. After the storage battery 3 is conveyed to the fixed area by the first conveyor belt 6, the storage battery 3 is blocked by the fixed plate 8, so that the first conveyor belt 6 no longer continues to transmit, and at this time, the injection head 4 can just push the acid injection head 5 to deflect its position, so as to realize acid injection.

[0025] When the acid injection is completed, a cylinder can be set at one end of the fixed plate 8 to push the fixed plate 8 through the cylinder, so that the fixed plate 8 drives the push plate 9 to push the battery 3 located in the fixed area onto the second conveyor belt 7.

[0026] Of course, during acid injection, the amount of acid injection is determined by calculating a certain time. If the acid injection needs to be stopped, the first conveyor belt 6 needs to be started so that the first conveyor belt 6 drives the battery 3 to transmit a certain distance in the reverse direction. The length of this distance needs to be greater than the diameter of the injection head 4, so that the acid injection head 5 is kept out of the injection head 4, thereby closing the acid injection, and then the cylinder can be started to push the fixed plate 8 through the cylinder, driving the battery 3 to transfer from the first conveyor belt 6 to the second conveyor belt 7, and the second conveyor belt 7 transports it to the designated position.

[0027] The battery 3 is provided with an injection head 4, the middle of the injection head 4 is hollowed out to form an injection hole 10, and the outside is provided with a thread. The injection head 4 is provided with a notch 12 to maintain the direction of movement toward the first conveyor belt 6. A first plane 13 is provided on the notch 12, and the height of the first plane 13 is lower than the acid injection head 5. When the injection head 4 pushes the acid injection head 5, the inner wall of the injection head 4 contacts the arc portion 14 of the acid injection head 5.

[0028] The acid injection mechanism 2 is provided with an acid injection box 15, a base 16, a seal 17 and an acid injection head 5. The acid injection mechanism 2 can realize rapid acid injection and simultaneous acid injection of multiple acid injection heads 5, and can perform acid injection work without adding a separate external force drive.

[0029] The acid injection box 15 can be an open box body 18 or a closed box body 18. The acid injection box 15 is composed of an annular box wall 19 and a first fixed body 20. The first fixed body 20 is located at the lower end of the annular box wall 19, and the first fixed body 20 is used to achieve connection with the base 16. A liquid storage chamber 21 is formed in the middle of the annular box wall 19.

[0030] The base 16 is installed at the lower end of the acid injection box 15, the seal 17 is connected to the acid injection head 5 and installed on the base 16, and the middle of the base 16 forms an injection chamber 22. The base 16 is composed of an annular body 23 and a second fixed body 24, and the second fixed body 24 is located at the upper end of the annular body 23.

[0031] The injection chamber 22 is provided with a first inner wall 25 and a second inner wall 26, and the first inner wall 25 and the second inner wall 26 are connected by a bottom wall 27, and the bottom wall 27 is arranged to be inclined downward from the first inner wall 25 to the second inner wall 26. The bottom wall 27 is provided with a plurality of movable holes 28, and a telescopic member 29 is arranged in the middle of the movable hole 28, and the acid injection head 5 is arranged in the telescopic member 29.

[0032] A pressure part 30 is provided inside the annular box wall 19, a pressure body 31 is provided on the bottom surface of the pressure part 30, an annular groove 32 matching with the pressure body 31 is provided on the annular body 23, a sealing ring 33 is provided in the annular groove 32, and the pressure body 31 squeezes the sealing ring 33 into the annular groove 32. The first fixed body 20 and the second fixed body 24 are fixed by bolts, which can avoid leakage between the acid injection box 15 and the base 16.

[0033] The seal 17 is composed of a sealing plate 34 and a stopper 35 symmetrically arranged on the seal 17, and a limit groove 36 is formed between the stoppers 35. A baffle 37 is arranged in the middle of the acid injection box 15, and a positioning column 38 is arranged at the lower end of the baffle 37. An elastic member 39 is sleeved on the positioning column 38, and the upper end of the elastic member 39 contacts the lower surface of the baffle 37, and the lower end is located in the limit groove 36.

[0034] Since the bottom wall 27 is arranged in an inclined state, the sealing member 17 is also in an inclined state when it is installed on the bottom wall 27. However, the positioning column 38 is installed vertically, so the lower end of the elastic member 39 remains inclined. In addition, the elastic member 39 is in a compressed state, so that the bottom surface of the sealing member 17 is tightly fitted with the bottom wall 27, and no liquid leakage occurs.

[0035] The lower end of the sealing member 17 is provided with a threaded hole 40 and an injection port 41, the threaded hole 40 and the injection port 41 are connected by an injection channel 42, and the lower surface of the sealing member 17 is kept in contact with the bottom wall 27 by the elastic force of the elastic member 39. When the sealing member 17 is separated from the bottom wall 27, the liquid enters the injection port 41 from the second inner wall 26.

[0036] The connection between the first inner wall 25 and the bottom wall 27 forms a first limiting point 43, the connection between the second inner wall 26 and the bottom wall 27 forms a second limiting point 44, and the sealing member 17 is located between the first limiting point 43 and the second limiting point 44. When the end in contact with the second limiting point 44 is opened, the end in contact with the first limiting point 43 rotates, and the center line of the acid injection head 5 coincides with the center line of the positioning column 38.

[0037] The center lines of the movable hole 28, the telescopic member 29 and the acid injection head 5 coincide with each other and are all arranged vertically with the bottom wall 27. There is an angle H between the center line of the positioning column 38 and the center line of the acid injection head 5. The acid injection head 5 can be pushed by the injection head 4 at H degrees or 2H degrees. If it is 2H degrees, the opening and closing angle between the sealing member 17 and the bottom wall 27 is larger, and the injection amount of the liquid is larger.

[0038] The acid injection head 5 is composed of a threaded portion 11, a mounting body 45 and a contact body 46 from top to bottom. The middle of the threaded portion 11 is hollowed out to form a countersunk hole 47, and the threaded portion 11 is installed in cooperation with the threaded hole 40. A connecting port 48 is provided on the threaded portion 11, and the connecting port 48 is connected to the countersunk hole 47. When the threaded portion 11 is installed in the threaded hole 40, the connecting port 48 is kept in communication with the injection port 41 through the injection channel 42. A through hole 49 connected to the countersunk hole 47 is formed in the middle of the mounting body 45 and the contact body 46. When the acid injection head 5 is installed, the telescopic member 29 is pushed to stretch.

[0039] The mounting body 45 is provided with symmetrically arranged notches 50, and a second plane 51 is provided in the notches 50. After the acid injection head 5 is placed in the telescopic member 29, the acid injection head 5 can be rotated by clamping it in the notches 50 with a tool so that the threaded portion 11 is butted with the threaded hole 40.

[0040] The telescopic member 29 is composed of a first connecting portion 52, a first arc-shaped portion 53, a second arc-shaped portion 54, a second connecting portion 55, a telescopic cylinder 56, a third arc-shaped portion 57 and a cylindrical portion 58. A mounting chamber 59 is formed in the middle of the telescopic cylinder 56, and an opening and closing area 60 is formed between the first arc-shaped portion 53 and the second arc-shaped portion 54. The telescopic member 29 is pushed by the acid injection head 5, so that the first arc-shaped portion 53, the second arc-shaped portion 54 and the second connecting portion 55 are deflected.

[0041] The telescopic cylinder 56 is provided with a plurality of wrinkles (not shown in the figure). When the acid injection head 5 is installed in the installation chamber 59, the acid injection head 5 pushes the telescopic cylinder 56 to straighten the wrinkles. The wrinkles can generate elastic force to maintain close contact with the acid injection head 5. An annular protrusion 61 is provided inside the telescopic cylinder 56, and an annular recess 62 matching the annular protrusion 61 is provided at the lower end of the installation body 45.

[0042] The middle of the cylindrical portion 58 is hollowed out to form a deformation chamber 63. A through opening 64 is provided at the lower end of the cylindrical portion 58. The contact body 46 is disposed in the cylindrical portion 58. An arc portion 14 is provided at the lower end of the contact body 46. The arc portion 14 expands the through opening 64 and is wrapped around the arc portion 14.

[0043] The first conveyor belt 6 drives the battery 3 to move, pushing the seal 17 and the bottom wall 27 to open and close, thereby achieving acid injection. The first conveyor belt 6 drives the battery 3 to move in the opposite direction, so that the elastic member 39 pushes the seal 17 and the bottom wall 27 to close, thereby closing the acid injection.
