[0016] The present invention will be further described below in conjunction with specific embodiments.

[0017] A device for adding electrolyte to button batteries, as shown in the following Figures 1 to 3 As shown, it includes a filling device and a conveying disc 1 for conveying button batteries.

[0018] The filling device mainly includes a base 2, a synchronous belt mechanism 3, an arc guide rail 4, and a liquid injection mechanism 5.

[0019] The upper portion of the base 2 is a planar panel 21 .

[0020] The synchronous belt mechanism 3 is installed on the base 2. The synchronous belt mechanism 3 includes a driving wheel 31, a passive wheel 32, an H-type synchronous belt 33, a servo motor 34, and a tensioner 35. The servo motor 34 is located below the panel 21 and is fixedly mounted on the panel 21. A through hole is provided on the panel 21. The output end of the servo motor 34 is vertically penetrated through the through hole and connected to the driving wheel 31 above the panel 21 to drive the driving wheel 31 to rotate. The passive wheel 32 is separated from the driving wheel 31 by a distance and is also above the panel 21. A through hole is provided on the panel 21. A pin 36 is vertically penetrated through the through hole. The upper end of the pin 36 is connected to the passive wheel 32. The tensioner 35 is located below the panel 21 and is fixedly mounted on the panel 21. The lower end of the pin 36 is connected to the tensioner 35. The H-type synchronous belt 33 is sleeved on the driving wheel 31 and the passive wheel 32. The servo motor 34 drives the driving wheel 31 to rotate, and can control its forward and reverse rotation, so that the driving wheel 31 drives the H-shaped synchronous belt 33 to transmit forward and reverse.

[0021] The circular arc guide rail 4 is installed on the base 2. The circular arc guide rail 4 includes a circular arc lower rail 41 and an upper slider 42. On one side of the length connection direction of the driving wheel 31 and the driven wheel 32, the circular arc lower rail 41 is located above the panel 21 and is fixed on the panel 21. The length direction of the circular arc lower rail 41 is consistent with the length connection direction of the driving wheel 31 and the driven wheel 32. The circular arc lower rail 41 is provided with a groove 43 with a V-shaped cross section on both sides of its length direction. The V-shaped opening of the groove 43 faces outward, and the opening length of the groove 43 is the length of the circular arc lower rail 41. The upper slider 42 is installed on the circular arc lower rail 41. The upper slider 42 is provided with a V-shaped protrusion 44 with a cross section matching the groove 43 at its lower part. The protrusion 44 and the groove 43 are inserted into each other, so that the upper slider 42 is connected to the circular arc lower rail 41 without being separated, and the upper slider 42 can slide along the circular arc lower rail 41.

[0022] The injection mechanism 5 is installed on the circular arc guide rail 4. The injection mechanism 5 includes a mounting seat 51 and a mounting plate 52. The mounting seat 51 is L-shaped, and its horizontal wall surface 53 is mounted and fixed on the upper slider 42. Its vertical wall surface 54 is located at the rear end of the injection mechanism 5, facing the H-type synchronous belt 33 and connected and fixed thereto. At the connection, a gasket 56 is also provided between the two. The mounting plate 52 is horizontally fixed on the horizontal wall surface 53, and the front end of the mounting plate 52 (i.e., the front end of the injection mechanism 5) extends out of the panel 21. The front end of the mounting plate 52 is provided with an injection pipe clamp interface 55. The injection pipe is introduced from the top of the mounting plate 52 and clamped in the injection pipe clamp interface 55. The outlet of the injection pipe faces downward to form a liquid outlet. The H-type synchronous belt 33 transmits forward and reversely, and drives the upper slider 42 and the injection mechanism 5 as a whole to reciprocate along the circular arc lower fixed rail 41. The H-type synchronous belt 33 is a flexible transmission form and can be adapted to the circular arc lower fixed rail 41.

[0023] The conveyor disc 1 is located on one side of the filling device, and outside the front end of the mounting plate 52, the arc lower fixed rail 41 is designed to be arranged concentrically with the conveyor disc 1, and the conveyor disc 1 rotates at its center. A number of battery slot stations 11 are evenly arranged on the circumferential edge of the conveyor disc 1. The button batteries to be continuously fed are arranged one by one in each battery slot station 11, and each button battery is continuously conveyed as the conveyor disc 1 rotates. The outward direction of the injection mechanism 5 is designed to be the same as the rotation direction of the conveyor disc 1, for example, Figure 1 As shown by the middle arrow, the liquid outlet of the injection tube needs to be designed to be located above the liquid inlet of the button battery.

[0024] In order to improve the production line efficiency, it is designed that the three batteries in the three consecutive battery slot stations 11 are filled with electrolyte at the same time. The filling mechanism 5 needs to reciprocate once in the rotation area of ​​the three battery slot stations 11 to complete a filling cycle, that is, on the conveying disc 1, every three consecutive batteries are divided into a unit group i (i.e., button battery C i ), the next unit group i+1 (i.e. button battery C i+1 ), and then the unit group i+2 (i.e. button battery C i+2 ), unit group i+3 (i.e. button battery C i+3 ),..., correspondingly, three injection pipe clamp interfaces 55 are arranged on the mounting plate 52, and the three injection pipe clamp interfaces 55 are arranged in sequence and the connecting line forms an arc arranged concentrically with the arc lower fixed rail 41 (and also with the conveying disc 1), and the liquid outlets of the injection pipes on the three injection pipe clamp interfaces 55 correspond one by one to the tops of the three battery liquid inlets.

[0025] Combined with Figure 4As shown, the injection mechanism is located at the initial position. During the outward process, a time period of 0.5 rotation positions is allocated for the injection mechanism to wait in place, and another time period of 0.5 rotation positions is allocated for the servo motor to accelerate and match the rotation speed of the conveying disc, so that the outlets of the three injection pipes of the injection mechanism correspond to the three battery inlets on the conveying disc one by one, and then a time period of 1 rotation position is allocated for the servo motor to uniformly adapt to the rotation speed of the conveying disc. The injection mechanism and the conveying disc move together at a uniform speed to complete the filling of electrolyte, and then a time period of 1 rotation position is allocated for the servo motor to reverse and return the injection mechanism to the initial position, completing a filling cycle.

[0026] In the next outbound process, the button battery C i+1 Fill the electrolyte. Figure 4 Only two unit groups with a total of 6 batteries are shown, and the batteries on other battery slots are not drawn.

[0027] The number of injection pipe card interfaces 55 opened and the number of injection pipes equipped are the same as the number j of batteries in a unit group i, and j can be at least 1.

[0028] The encoder and servo motor can cooperate to realize rhythm control. The encoder controls the speed of each section of the servo motor to achieve temporary synchronization with the conveying disc. The arc lower track determines that the relative position of the injection tube and the conveying disc remains unchanged during the uniform speed following stage.

[0029] The accompanying electrolyte filling equipment designed by the utility model follows the continuous conveying speed of the button batteries during the continuous conveying process of the button batteries, fills a group of multiple batteries at the same time, and completes the filling process of the batteries in the conveying sequence in sequence without omission and with accurate filling, which is beneficial to improving the production speed of the production line to increase the profit of the enterprise.
