[0026] Reference Figure 1 A blade battery positioning mechanism includes a base 1 and a top cover positioning component 2 and a protective cover follower component 3 installed on the base 1, referring to Figure 2 and Figure 3 The top cover positioning assembly 2 includes a positioning block 20 and a positioning block Y-axis translation module. The positioning block 20 is provided with a positioning reference surface. The positioning block Y-axis translation module is used to drive the positioning block 20 to move along the Y-axis direction, that is, to move in the direction in which the welding fixture clamps the battery. The positioning reference surface on the positioning block 20 contacts the end face of the battery top cover on the welding fixture for positioning. In order to improve the positioning effect, the positioning blocks 20 are at least two, and the positioning blocks 20 include a left positioning block 20a and a right positioning block 20b. The left and right positioning blocks can respectively position the two ends of the battery top cover, thereby improving the positioning effect.

[0027] Reference Figure 2 and Figure 3The Y-axis translation module of the positioning block includes a support plate 21, a first linear guide 23, a mounting plate 24 and a first driving unit. The support plate 21 is fixedly mounted on the base 1. The slide rail part of the first linear guide 23 is fixedly mounted on the support plate 21 through the support block 22. The mounting plate 24 is fixedly connected to the slider part of the first linear guide 23, so that the mounting plate 24 can slide relative to the support plate 21, and the positioning block 20 is mounted on the mounting plate 24. Therefore, when the mounting plate 24 moves, the positioning block 20 moves synchronously. In this embodiment, the first driving unit adopts a square cylinder 26. A first cylinder mounting plate 25 is fixedly connected to the support plate 21. The square cylinder 26 is mounted on the first cylinder mounting plate 25. The end of the piston rod of the square cylinder 26 is connected to the mounting plate 24. Therefore, when the square cylinder 26 is extended and retracted, it can drive the mounting plate 24 to move forward or backward along the Y-axis, that is, drive the positioning block 20 to move toward the battery top cover or in the opposite direction.

[0028] Furthermore, an oil pressure buffer 27 is arranged between the support plate 21 and the mounting plate 24. Specifically, a buffer mounting plate 28 is fixedly connected to the support plate 21, one end of the oil pressure buffer 27 is mounted on the buffer mounting plate 28, and the other end of the oil pressure buffer 27 is mounted on the mounting plate 24. Through the setting of the oil pressure buffer 27, during the retraction of the piston rod of the square cylinder 26, a limiting effect is played on the movement of the mounting plate 24.

[0029] In this embodiment, refer to Figure 4 , Figure 5 and Figure 6 The protective cover follower assembly 3 includes a protective cover 30, a protective cover rotating module, a protective cover Y-axis translation module and a protective cover pre-positioning module. The protective cover rotating module includes an adjustment plate 39 and a rolling bearing 311 fixed on the adjustment plate 39. The center hole of the rolling bearing 311 is connected with a rotating shaft 312. The protective cover 30 is fixedly connected to the end of the rotating shaft 312 through an adjustment block 310. Specifically, the adjustment block 310 is fixedly connected to the end of the rotating shaft 312. A guide member and an elastic member are connected between the protective cover 30 and the adjustment block 310. The protective cover 30 can move in the Y-axis direction through the guide member and the elastic member.

[0030] Furthermore, the guide member includes a linear bearing 313 fixedly connected to the adjustment block 310, the center hole of the linear bearing 313 is slidably connected to a guide shaft 314, the end of the guide shaft 314 is fixedly connected to the protective cover 30, and an anti-slip block is provided at the end of the guide shaft 314 away from the protective cover 30.

[0031] Furthermore, the elastic member is a compression spring, which is sleeved on the guide shaft 314. One end of the compression spring abuts against the protective cover 30, and the other end abuts against the adjusting block 310. When the guide shaft 314 slides in the linear bearing 313, the protective cover 30 moves toward the adjusting block 310, thereby compressing the compression spring, that is, the compression spring provides an elastic force acting on the protective cover 30, so that the protective cover 30 fits flexibly on the battery top cover, thereby avoiding excessive force when the protective cover 30 is in hard contact with the battery top cover, causing damage to the battery top cover.

[0032] Through the above arrangement, when the battery top cover is positioned, the protective cover 30 is attached to the battery top cover to protect the pole, and when the welding fixture drives the battery and the top cover to rotate and weld, under the action of the rolling bearing 311 and the rotating shaft 312, the protective cover 30 rotates synchronously with the battery top cover, achieving the effect of perfect following of the protective cover 30 and the battery top cover, thereby continuously protecting the pole and the top cover during the welding process to avoid damage to the pole and scratches on the top cover.

[0033] In this embodiment, refer to Figure 3 The protective cover Y-axis translation module includes a base plate 31, a second linear guide 33, a fixed plate 32, and a second driving unit. The slide rail part of the second linear guide 33 is fixedly connected to the base plate 31, and the fixed plate 32 is fixedly connected to the slider part of the second linear guide 33, that is, the fixed plate 32 can move relative to the base plate 31. The adjustment plate 39 is installed on the fixed plate 32. The second driving unit adopts a thin cylinder 35. The thin cylinder 35 is fixedly connected to the base plate 31 through a second cylinder mounting plate 34. The piston rod of the thin cylinder 35 is connected to the fixed plate 32 through a fisheye joint, so that the thin cylinder 35 drives the fixed plate 32 to move when it is extended and retracted, and then drives the adjustment plate 39 and the protective cover 30 to move, so that the protective cover 30 can be translated to fit on the battery top cover.

[0034] In this embodiment, refer to Figure 3The protective cover pre-positioning module includes a top block 38 and a third driving unit. A protective cover positioning surface is provided on the top block 38. The third driving unit adopts a slide cylinder 37. The fixed plate 32 is connected to a third cylinder mounting plate 36. The slide cylinder 37 is mounted on the third cylinder mounting plate 36, so that the protective cover pre-positioning module can translate with the fixed plate 32. The top block 38 is fixedly connected to the piston rod of the slide cylinder 37. When the slide cylinder 37 is extended, it can drive the top block 38 to move upward. The protective cover positioning surface on the top block 38 pre-positions the bottom surface of the protective cover 30, so that the protective cover 30 is in a horizontal state, and the protective cover 30 and the positioning block 20 are in the same horizontal plane, so that the protective cover 30 can be accurately fitted on the battery top cover when the battery is positioned, thereby protecting the top cover and the pole.

[0035] The use process of the blade battery positioning mechanism of the utility model is as follows: 1. The square cylinder 26 pushes the mounting plate 24 to move along the y-axis direction, and the positioning block 20 pre-positions the battery; 2. After the battery is pre-positioned, the thin cylinder 35 drives the fixing plate 32 to move along the y-axis direction, so that the protective cover 30 is tightly buckled with the battery top cover, and the positioning action on the protective cover 30 is completed. During this period, the slide cylinder 37 is always in an extended state, so that the top block 38 maintains the state of pre-positioning the protective cover 30; 3. After the protective cover 30 is positioned, the slide cylinder 37 retracts, and at the same time the square cylinder 26 retracts, and the protective cover 30 and the battery maintain a follow-up state and rotate synchronously with the welding fixture.
