[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-4As shown, the battery bracket positioning mechanism is characterized by comprising multiple sets of support devices 1, each set of support devices 1 being arranged parallel to each other. The lower end of each support device 1 is fixedly installed on the production line, and a positioning component is provided at the upper end of each support device 1. The positioning component includes a first support plate 11, a second support plate 12, and a floating structure 13. The floating structure 13 is provided between the first support plate 11 and the second support plate 12. The first support plate 11 moves relative to the second support plate 12 through the floating structure 13. The first support plate 11 is used to support the bracket of the automobile battery. The second support plate 12 is fixedly installed to the support device 1. The floating structure 13 includes a cross block 131. A transverse movable part 132 and a longitudinal movable part 133 are respectively provided around the cross block 131. The transverse movable part 132 and the longitudinal movable part 133 move relative to each other. The battery tray is vertically mounted with a lateral movable part 132 installed at the lower end of the first support plate 11 and a longitudinal movable part 133 installed at the upper end of the second support plate 12. The cross block 131 moves synchronously with the first support plate 11 along the Y-axis via the lateral movable part 132 and synchronously with the first support plate 11 along the X-axis via the longitudinal movable part 133. A floating structure 13 is provided, which can drive the car battery tray to reset when a positional deviation occurs, greatly improving the positioning accuracy and ensuring the accuracy of subsequent assembly processes. This solves the problem of inaccurate placement caused by shaking during the hoisting of the car battery tray. In addition, multiple sets of support devices 1 are provided, which can form multi-point balanced support, effectively distributing the weight of the battery tray and avoiding deformation or shaking of the tray caused by excessive local stress.

[0034] like Figure 4 and Figure 5The lateral movable part 132 shown includes two sets of opposing lateral movable units. Each set of lateral movable units is arranged on both sides of the cross block 131 along the Y-axis. The lateral movable unit includes a first slider 1321, a first screw 1322, and a first spring 1323. Two first sliders 1321 are fixedly installed at the lower end of the first support plate 11. The two first sliders 1321 are arranged parallel to each other. A first screw 1322 is slidably connected inside each first slider 1321. One end of the first screw 1322 is threaded to the outer periphery of the cross block 131, and the other end of the first screw 1322 is sleeved with the first spring 1323. One end of the first spring 1323 abuts against the first slider 1321. On the outside of 321, the other end of the first spring 1323 abuts against the other end of the first screw 1322. When the floating structure 13 moves along the X-axis, the second screw 1332 slides within the second slider 1331 along the X-axis. The two first sliders 1321 slide along the X-axis following the first support plate 11. The position of the cross block 131 moves relative to the second support plate 12 along the X-axis, while the position of the cross block 131 does not move relative to the first support plate 11. During the movement, the first spring 1323 on one side is stretched, and the first spring 1323 on the other side is compressed. Under the action of the elastic force of the first spring 1323 itself, the first support plate 11 moving along the X-axis will be pulled back to its original position.

[0035] like Figure 4 and Figure 6 As shown, the longitudinal movable part 133 includes two sets of opposing longitudinal movable units. Each set of longitudinal movable units is arranged on both sides of the cross block 131 along the X-axis. The longitudinal movable unit includes a second slider 1331, a second screw 1332, and a second spring 1333. Two second sliders 1331 are fixedly installed on the upper end of the second support plate 12. The two second sliders 1331 are arranged parallel to each other. A second screw 1332 is slidably connected inside each second slider 1331. One end of the second screw 1332 is threaded to the outer periphery of the cross block 131, and the other end of the second screw 1332 is sleeved around the outer periphery of the second spring 1333. One end of the second spring 1333 abuts against the outer side of the second slider 1331, and the other end of the second spring 1333 abuts against the second screw. Inside 1332, when the floating structure 13 moves along the Y-axis, the first screw 1322 slides within the first slider 1321 along the Y-axis. The two first sliders 1321 slide along the Y-axis following the first support plate 11. The position of the cross block 131 moves relative to the second support plate 12 along the Y-axis, while the position of the cross block 131 does not move relative to the first support plate 11. During the movement, the second spring 1333 on one side is stretched, and the second spring 1333 on the other side is compressed. Under the action of the elastic force of the second spring 1333 itself, the first support plate 11 moving along the Y-axis will be pulled back to its original position. The combination of the two movement modes allows the floating structure 13 to move arbitrarily in the two-dimensional plane, and it will automatically reset under the action of the springs during the movement.

[0036] like Figure 5 As shown, multiple shims 14 are provided between each first slider 1321 and the first support plate 11. These shims 14 are arranged parallel to each other and are used to adjust the relative position of the axis of the first screw 1322. By adding or removing the number of shims 14, the relative position of the axis of the first screw 1322 can be adjusted, ensuring smooth sliding of the outer periphery of the first screw 1322 within the first slider 1321, thereby increasing the mobility of the floating device 13. By providing multiple shims 14 between the first slider 1321 and the first support plate 11, the relative position of the axis of the first screw 1322 can be adjusted, ensuring smooth sliding of the outer periphery of the first screw 1322 within the first slider 1321. This enhances the flexibility of the floating structure 13, better adjusts the car battery bracket whose position has shifted, and improves work efficiency.

[0037] like Figure 6 and Figure 7 As shown, multiple sliding plates 15 are arranged circumferentially at the lower end of the first support plate, and multiple protrusions 16 are arranged circumferentially at the upper end of the second support plate 12. The protrusions 16 correspond one-to-one with the sliding plates 15. The lower end of the sliding plate 15 contacts the upper end of the protrusion 16. The protrusion 16 includes a sleeve 161. The second support plate 12 is provided with multiple through holes, and a sleeve 161 is installed in each through hole. Each sleeve 161 is provided with a ball bearing 162 at its upper end. The outer periphery of the ball bearing 162 is rotatably connected to the lower end of the sliding plate 15. The outer periphery of the upper end of the sleeve 161 is provided with an annular boss. The outer periphery of the sleeve 161 is located in the through hole. The lower end of the annular boss is engaged with the upper end of the second support plate 12. A rubber ring 163 is provided between the lower end of the annular boss and the upper end of the second support plate 12. The ball bearing 162 can roll at the lower end of the sliding plate 15, which can better drive the first support plate 11 to slide.

[0038] like Figure 5 As shown, a positioning block 17 is provided at the upper end of the first support plate 11. When the car battery bracket is transferred to the positioning component by the hoisting equipment, the positioning block 17 plays a guiding and positioning role. The bottom of the battery bracket is provided with a groove or square hole that matches the positioning block 17. The outer periphery of the positioning block 17 is inserted into the groove or square hole to achieve the positioning effect. The fitting state of the positioning block 17 and the groove or square hole on the car battery bracket will fix the relative position of the battery bracket and the support plate 11. When the floating structure 13 moves, the bracket can follow the movement synchronously through the fitting of the positioning block 17 to achieve the purpose of accurate positioning.

[0039] Working process of the battery bracket positioning mechanism:

[0040] Multiple sets of parallel support devices 1 are fixedly installed on the production line at their lower ends to ensure stable support. Then, the positioning components are assembled on the upper end of the support devices 1. A hoisting device transfers the car battery bracket to the positioning mechanism. When the bracket descends, the positioning block 17 on the upper end of the first support plate 11 first aligns with the groove or square hole at the bottom of the bracket. With the help of the positioning block 17, the bracket is placed on the upper end of the first support plate 11. After the bracket is fully placed, if there is a positional deviation, the floating structure 13 is triggered for reset and calibration. When the bracket deviates along the X-axis, the first support plate 11 drives the first slider 1321 of the transverse movable part 132 to move along the X-axis. The cross block 131 moves along the X-axis via the second screw 1332 of the longitudinal movable part 133. The sliding of the two sliders 1331 causes the cross block 131 to return to the center position, thereby driving the first support plate 11 and the bracket to reset along the X-axis. When the bracket deviates along the Y-axis, the first support plate 11 drives the first screw 1322 of the transverse movable part 132 to slide along the Y-axis inside the first slider 1321. The elastic force of the first spring 1323 drives the cross block 131 to return to the center position, driving the first support plate 11 and the bracket to reset along the Y-axis. The combination of the two working processes can reset any deviation in the two-dimensional plane. When the floating structure 13 completes the reset, the cross block 131 returns to the center position. At this time, the car battery bracket is placed at the center position of the upper end of the mechanism, which is convenient for downstream processes.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
