[0030] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0031] Example 1

[0032] See also Figure 1 This embodiment introduces a battery shell preprocessing tool, including a base 1, a positioning component 2 and a cutting tool 3.

[0033] like Figure 2 and Figure 3 As shown, the positioning assembly 2 and the cutting tool 3 are both installed on the base 1. The positioning assembly 2 is mainly composed of a lifting member 21, a positioning bottom plate 22 and a positioning side plate 23. The lifting member 21 includes a hand-cranked lifting frame 212 and a slide plate 211. The slide plate 211 is slidably arranged on the top of the base 1. A slide groove adapted to the slide plate 211 can be opened on the top of the base 1. The slide plate 211 is placed in the slide groove. The slide plate 211 slides along the length direction of the slide groove. In order to prevent the slide plate 211 from detaching from the top of the base 1, a limiting protrusion is arranged at the bottom of the slide plate 211. The limiting protrusion is in a "T" shape. A limiting groove adapted to the limiting protrusion is opened at the top of the slide groove. The limiting protrusion is located in the limiting groove and cooperates with the slide plate 211 to slide on the base 1. The sliding direction of the slide plate 211 is the marking direction of the battery.

[0034] The sliding of the slide plate 211 can be manually pushed or mechanically controlled. If mechanical control is adopted, Figure 4 As shown, the top of the base 1 is fixedly connected to the telescopic cylinder 4, the telescopic cylinder 4 is horizontally arranged, and the telescopic direction is consistent with the sliding direction of the slide plate 211. The movable end of the telescopic cylinder 4 is connected to the slide plate 211, and the slide plate 211 can be driven to slide by the telescopic cylinder 4. The telescopic cylinder 4 is installed at one end of the slide slot, and the baffle 5 is installed at the other end of the slide slot to prevent the slide plate 211 from detaching from the end of the slide slot.

[0035] The bottom of the hand-cranked lifting frame 212 is fixedly connected to the slide plate 211, and the slide plate 211 drives the hand-cranked lifting member 21 to move horizontally. The top of the hand-cranked lifting frame 212 is fixedly connected to the positioning base plate 22 as a movable end, and can be detachably connected by bolts or other connection methods. The hand-cranked lifting frame 212 meets the height adjustment of the positioning base plate. There are three positioning side plates 23, which are respectively located on the top three side edges of the positioning base plate 22. The battery is located on the positioning base plate 22 and is surrounded by the three positioning side plates 23. The end of the battery that does not contact the positioning side plate 23 is marked or cut by a cutting tool 3.

[0036] The positioning side plates 23 are connected to the positioning bottom plate 22 by sliding. The three positioning side plates 23 can change their positional relationship with each other by sliding horizontally to accommodate batteries of different sizes. In order to improve the sliding stability of the positioning side plates 23, a T-block is fixed to the bottom of the positioning side plates 23, and a T-slot adapted to the T-block is provided at the top of the positioning bottom plate 22 along the sliding direction of the positioning side plates 23. The T-block is located in the T-slot to ensure that the positioning side plates 23 slide stably.

[0037] like Figure 3 As shown, in order to stabilize the relative position of the positioning side plate 23 and the positioning bottom plate 22 after the positioning side plate 23 contacts the battery, an adjustment block 24 is fixed to the outer bottom of the positioning side plate 23, and a hole is longitudinally opened in the middle of the adjustment block 24 to facilitate the limiting bolt 25 to longitudinally pass through the adjustment block 24. The threaded section of the limiting bolt 25 passes through the adjustment block 24. In order to facilitate the limiting bolt 25 to pass through the positioning bottom plate 22, the positioning bottom plate 22 is provided with a limiting sliding hole, and the length direction of the limiting sliding hole is consistent with the sliding direction of the positioning side plate 23. The moving directions are consistent, and the adjusting block 24 is located at the top of the limiting sliding hole. Therefore, the threaded section of the limiting bolt 25 passes through the adjusting block 24 and then continues to pass through the limiting sliding hole of the positioning side plate 23 and is located below the positioning side plate 23. The limiting nut of the limiting bolt 25 is located at the bottom of the positioning side plate 23. The nut is rotated to make the nut fit tightly with the bottom of the positioning side plate 23, thereby positioning the adjusting block 24, so that the adjusting block 24 cannot slide easily on the positioning side plate 23, thereby achieving the purpose of limiting the positioning side plate 23.

[0038] like Figure 1 As shown, the cutting tool 3 is mainly composed of a fixing frame 31, a motor 32 and a circular blade 33. The fixing frame 31 is fixedly connected to the top of the base 1, and the installation position of the fixing frame 31 is located beside the positioning bottom plate 22, and close to the side of the positioning bottom plate 22 without the positioning side plate 23. The motor 32 is installed on the top of the fixing frame 31, and the output shaft of the motor 32 is connected to the circular blade 33. The rotation direction of the circular blade 33 is adapted to the horizontal sliding direction of the lifting member 21. That is, the bottom of the circular blade 33 can contact the battery without being blocked by the positioning side plate 23, and the sliding of the slide plate 211 cooperates with the circular blade 33 to perform the marking or cutting operation on the battery.

[0039] Compared with the traditional method of marking with a utility knife, this embodiment is simple to operate, has a high effect, and can effectively reduce the workload of employees; it can be applied to square aluminum shell batteries of various thicknesses or widths and has a wide range of applications.

[0040] Example 2

[0041] like Figure 5As shown, this embodiment introduces a battery shell pretreatment tool, which is basically the same as the battery shell pretreatment tool introduced in Example 1. The difference is that the lifting member 21 of this embodiment adopts a slide plate 211 and an electric lifting rod 123, and the electric lifting rod 123 replaces the hand-cranked lifting frame 212, and the mechanical part replaces the manual part, which is more precise in control.

[0042] This embodiment has the same beneficial effects as Embodiment 1.

[0043] Example 3

[0044] like Figure 6 As shown, this embodiment introduces a battery shell preprocessing tool, which is basically the same as the structure of the battery shell preprocessing tool introduced in Example 1. The difference is that this embodiment uses an adjustment block 24, a limit rod 26 and a spring 27 to position the positioning side plate 23. An adjustment block 24 is fixedly connected to the bottom of the side of the positioning side plate 23 away from the battery. The adjustment block 24 has a hole in the longitudinal direction to facilitate the limit rod 26 to pass through the adjustment block 24. In order to facilitate the limit rod 26 to pass through the positioning bottom plate 22, a limit sliding hole is provided on the surface of the positioning bottom plate 22 along the sliding direction of the positioning side plate 23. The adjustment block 24 is located at the top of the limit sliding hole. One end of the limit rod 26 passes through the adjustment block 24 and the limit sliding hole and is located below the positioning bottom plate 22. The top end of the limit rod 26 is located above the adjusting block 24, and the bottom end is located at the bottom of the positioning base plate 22. Both ends of the limit rod 26 extend radially to form circular protrusions. A spring 27 is arranged between the adjusting block 24 and the circular protrusion on the top of the limit rod 26. The spring 27 pushes the limit rod 26 upward so that the circular protrusion at the bottom end of the limit rod 26 is close to the bottom of the positioning base plate 22. Since the diameter of the circular protrusion is greater than the width of the limiting sliding hole, the circular protrusion will not pass through the limiting sliding hole. The circular protrusion at the bottom end of the limit rod 26 is close to the positioning base plate 22, so that the sliding of the adjusting block 24 is restricted, thereby restricting the sliding of the positioning side plate 23 on the positioning base plate 22.

[0045] This embodiment has the same beneficial effects as Embodiment 1.

[0046] Example 4

[0047] like Figure 7 As shown, this embodiment introduces a battery shell preprocessing tool, which is basically the same as the battery shell preprocessing tool introduced in Example 1. The difference is that this embodiment adopts a fixing frame 31 and an adjusting bolt 29 to position the positioning side plate 23. The positioning bottom plate 22 has three side edges of the positioning side plate 23 fixedly connected with a fixing plate 28, and the surface of the fixing plate 28 is horizontally threaded with an adjusting bolt 29, and the end of the adjusting bolt 29 is in contact with the positioning side plate 23. By rotating the adjusting bolt 29 so that its end is close to the positioning side plate 23, the sliding of the positioning side plate 23 on the positioning bottom plate 22 is limited.

[0048] This embodiment has the same beneficial effects as Embodiment 1.

[0049] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
