[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1-4An automatic lithium thionyl chloride battery filling machine with positioning function is shown, including a base 1, an L-shaped plate 2 fixedly installed on the top of the base 1, a cylinder 6 installed on the top of the L-shaped plate 2, the output end of the cylinder 6 passing through the top of the L-shaped plate 2 and fixedly installed with a rectangular extrusion block 7, an inclined groove opened at the bottom of the rectangular extrusion block 7, and L-shaped fixing rods 8 fixedly installed on both sides of the rectangular extrusion block 7. A filling mechanism is installed on the top of the base 1, and the two L-shaped fixing rods 8 are connected to the filling mechanism. A placement sleeve 9 corresponding to the filling mechanism is fixedly installed on the top of the base 1. Four positioning mechanisms are installed on the placement sleeve 9 with uniform circumferential arrangement. The four positioning mechanisms are installed in cooperation through a transmission mechanism. An L-shaped connecting rod 21 is installed on one of the positioning mechanisms near the rectangular extrusion block 7. An extrusion wheel 23 is rotatably installed on the top of the L-shaped connecting rod 21 and contacts the inner wall of the inclined groove.

[0022] With the above structure: In use, the lithium thionyl chloride battery is placed in the placement sleeve 9, and then the cylinder 6 is activated. The output end of the cylinder 6 stretches and drives the rectangular extrusion block 7 to move, thereby causing the inclined groove extrusion wheel 23 to move, which in turn causes the L-shaped connecting rod 21 to move, which in turn causes one positioning mechanism to move. One positioning mechanism moves the other three positioning mechanisms through the transmission mechanism, so that the four positioning mechanisms simultaneously perform automatic positioning of the lithium thionyl chloride battery. After positioning is completed, the inclined groove separates from the extrusion wheel 23, and the output end of the cylinder 6 continues to stretch so that the liquid injection mechanism corresponds to the lithium thionyl chloride battery, thereby automatically injecting liquid.

[0023] The liquid injection mechanism includes a liquid injection pump 3 fixedly installed on the top of the L-shaped plate 2. The outlet pipe of the liquid injection pump 3 passes through the top of the L-shaped plate 2 and a liquid injection telescopic pipe 4 is fixedly installed thereon. A liquid injection head 5 is fixedly installed at the bottom end of the liquid injection telescopic pipe 4. The ends of two L-shaped fixing rods 8 that are close to each other are fixedly installed on the side of the liquid injection head 5. The output end of the cylinder 6 stretches, causing the rectangular extrusion block 7 to move downward, thereby causing the two L-shaped fixing rods 8 to move downward. The movement of the L-shaped fixing rods 8 causes the liquid injection head 5 to move downward, stretching the liquid injection telescopic pipe 4. The liquid injection head 5 then contacts the lithium thionyl chloride battery, thereby performing the liquid injection operation.

[0024] The top of the base 1 has a groove, and a slider 22 is slidably installed in the groove. The top of the slider 22 is fixedly connected to the bottom of the L-shaped connecting rod 21. The groove and slider 22 facilitate the limiting of the L-shaped rod 21.

[0025] The positioning mechanism includes an arc-shaped groove on the inner wall of the placement sleeve 9. Two sliding holes are formed on the inner wall of the arc-shaped groove, and a U-shaped column 11 is slidably installed within each hole. Both ends of the U-shaped column 11 extend into the arc-shaped groove and are fixedly mounted with arc-shaped pressure plates 10. The side of the U-shaped column 11 near the rectangular pressing block 7 is fixedly connected to the bottom end of the L-shaped connecting rod 21. The positioning mechanism also includes a reset block 18 fixedly installed at the bottom of the U-shaped column 11. A reset hole is formed on the side of the reset block 18, and a reset rod 19 is slidably installed within the reset hole. Both ends of the reset rod 19 extend into the reset hole, and one end of the reset rod 19 is fixedly connected to the side of the placement sleeve 9. A reset spring 20 is sleeved on the reset rod 19, and both ends of the reset spring 20 are fixedly installed on the adjacent sides of the reset block 18 and the placement sleeve 9. Once the lithium thionyl chloride battery is aligned, the extrusion roller 23 separates from the inclined groove of the rectangular extrusion block 7 and contacts the vertical side of the rectangular extrusion block 7, thus no longer being extruded. This prevents the positions of the three arc-shaped pressure plates 10 from changing. Then, the rectangular extrusion block 7 continues to move, causing the injection head 5 to contact the lithium thionyl chloride battery, thereby performing the injection operation. During the movement of the U-shaped column 11, the reset block 18 moves, causing the reset spring 20 to deform. Under the reaction force of the reset spring 20, when the rectangular extrusion block 7 retracts after the lithium thionyl chloride battery is injected, the four U-shaped columns 11 return to their original shape, thereby releasing the lithium thionyl chloride battery to facilitate the insertion of the next lithium thionyl chloride battery.

[0026] The transmission mechanism includes a sliding ring 15 that is slidably sleeved on the placement sleeve 9. A lower right-angled triangular block 17 is fixedly installed at the bottom of the sliding ring 15. A lower pressure rod 12 is provided below the lower right-angled triangular block 17. The bottom end of the lower pressure rod 12 is fixedly installed on the bottom inner wall of the U-shaped column 11 near the L-shaped connecting rod 21. An upper inclined groove is provided at the top of the lower pressure rod 12. The inner wall of the upper inclined groove is slidably connected to the inclined side of the lower right-angled triangular block 17. Three upper right-angled triangular blocks 16 are fixedly installed at the top of the sliding ring 15. An upper pressure rod 13 is provided above each of the three upper right-angled triangular blocks 16. A lower inclined groove is provided at the bottom of each of the three upper pressure rods 13. The top ends of the three upper pressure rods 13 are respectively fixedly installed on the top inner wall of the three U-shaped columns 11 away from the L-shaped connecting rod 21. The inner walls of the three lower inclined grooves are slidably connected to the inclined sides of the three upper right-angled triangular blocks 16. In use, the lithium thionyl chloride battery is placed in the placement sleeve 9, and then the cylinder 6 is activated. At the same time, the inclined groove of the rectangular extrusion block 7 extrudes the extrusion wheel 23, causing it to move. The movement of the extrusion wheel 23 drives the L-shaped connecting rod 21 to move closer to the placement sleeve 9. The movement of the extrusion wheel 23 drives a U-shaped column 11 to move. The movement of the U-shaped column 11 causes one of the arc-shaped pressure plates 10 to move. The movement of the U-shaped column 11 causes the upper inclined groove on the lower pressure rod 12 to extrude the inclined side of the lower right-angled triangular block 17, thereby causing the lower right-angled triangular block 17 to move upward. The movement of the lower right-angled triangular block 17 drives the sliding ring 15 to move upward, thereby causing the three upper right-angled triangular blocks 16 to move upward. The inclined sides of the three upper right-angled triangular blocks 16 extrude the lower inclined groove of the upper pressure rod 13, thereby causing the three upper pressure rods 13 to move. The movement of the three upper pressure rods 13 drives the other three U-shaped columns 11 to move, thereby causing the other three arc-shaped pressure plates 10 to move. This extrudes and positions the lithium thionyl chloride battery from four sides, facilitating electrolyte injection.

[0027] The top of the sliding ring 15 has multiple circular holes, and a circular rod 14 is slidably installed in each of the holes. The bottom ends of the circular rods 14 are fixedly installed on the top of the base 1. The circular rods 14 are used to limit the sliding ring 15, allowing it to slide only.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
