Description
Technical Field
[0001] The utility model relates to the technical field of workpiece line engraving, in particular to a line engraving device. Background Art
[0002] like Figure 1 As shown, the shell of the current battery is generally designed to include a shell 10 and a top cover 20, wherein the shell 10 is provided with a mounting groove for accommodating the battery cell, and the top cover 20 and the shell 10 are welded. After the top cover 20 and the shell 10 are welded, the notch of the mounting groove will be sealed, so that the battery cell is protected in the shell. At present, when the battery is subjected to destructive testing or when the internal battery cell needs to be recovered later, the shell needs to be disassembled. The current disassembly method is that the operator holds the battery with one hand and uses a metal knife to score with the other hand. The purpose of scoring is to form a score groove 30 on the surface of the shell to reduce the thickness of the shell. After scoring a circle, the operator uses pliers to apply force to the prism of the shell to cause the shell to crack an opening at the prism, and then gradually peels the shell into two parts along the score groove 30. During the above disassembly process, due to the size of the battery cell and the marking technique, the marking lines are often not straight and the depth of the marking lines is different. This will cause the shell to be easily scratched when the pliers are used to break the shell. When the shell is broken, it may even cause the battery cell to be punctured. In addition, the marking process may easily scratch the hands due to the technique. These factors will greatly affect the work efficiency and work safety of the dismantler. Utility Model Content

[0031] In order to make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0032] Please refer to Figures 2 to 4, an embodiment of the present utility model provides a scribing device, which mainly includes a base 1, a jig 2, a cross beam 3, a support wall 4 and two cutting tools 5. Among them, the jig 2 is fixed on the top of the base 1, and the jig 2 is used to limit the position of the workpiece to be scribed. Preferably, the jig 2 limits the position of the workpiece to be scribed by setting a limit groove on the top. In this embodiment, the workpiece to be scribed is mainly exemplified by a battery 6; among them, the support walls 4 are provided on both opposite sides of the jig 2, the support walls 4 are fixed on the base 1, one end of the cross beam 3 and one side of the support wall 4 are slidably connected along a first direction (the first direction is preferably the horizontal X direction), and the other end of the cross beam 3 and the support wall 4 on the other side are also slidably connected along the X direction. The cross beam 3 and the support walls 4 on both sides can be Figure 3 as shown in the figure to achieve sliding connection through a connecting guide rail 7, or can also achieve sliding connection through a connecting guide rod. And the two cutting tools 5 are both connected to the cross beam 3, and the two cutting tools 5 are both used for scribing the outer surface of the battery 6 located on the jig 2. The cutting edge of the cutting tool 5 is a sharp angle, and the angle of the cutting edge of the cutting tool 5 is between 20° and 120°. The central axis of the cutting edge of the cutting tool 5 is perpendicular to the outer surface of the battery 6.
[0033] Before operation, it is necessary to pre-place the battery 6 on the jig 2 and pre-adjust the position of the cutting tool 5 relative to the cross beam 3; during operation, only need to push the cross beam 3 to move along the X direction, then the two cutting tools 5 can be driven to scribe the outer surface of the battery 6 straightly along the X direction at the same time. Using the scribing device of this solution, the scribing work of the outer shell of the battery 6 can be completed quickly, the scribing efficiency can be improved, and thus the subsequent disassembly efficiency of the battery 6 can be improved. Moreover, using the scribing device of this solution can also improve the scribing accuracy, solving problems such as uneven scribing or poor scribing depth caused by manual operation errors in traditional manual work. Since this solution is beneficial to improving the scribing accuracy, there will be no problem of scratching the internal battery core or piercing the electrode sheet during the subsequent disassembly of the battery 6, and at the same time, the scribing difficulty of the operator is reduced, and the risk of scratching the hand is reduced, improving the safety of the subsequent disassembly process of the battery 6. For the convenience of operation, a handle can also be fixed at both ends of the cross beam 3 in the Y direction.
[0034] In this embodiment, both of the two tools 5 are adjustable relative to the cross beam 3 in the second direction (the second direction is preferably the horizontal Y direction), wherein the Y direction is perpendicular to the X direction. Through such a design, the distances between the two tools 5 and the battery 6 located on the fixture 2 can be adjusted. On the one hand, the depths of the outer shell of the battery 6 scribed by the two tools 5 can be adjusted. On the other hand, the tools 5 can be compatible with the scribing operations of batteries 6 with different width dimensions, making the scribing device have the advantage of high compatibility. In addition, both of the two tools 5 are also adjustable relative to the cross beam 3 in the third direction (the third direction is preferably the vertical Z direction), so that the heights of the two tools 5 can be adjusted to facilitate adjusting the actual position of the tool 5 for scribing the battery 6, and at the same time, it can also be compatible with the scribing operations of batteries 6 with different height dimensions.
[0035] In this embodiment, scale lines 31 are provided on the top surface of the cross beam 3, and a zero point is provided at the middle position between the two tools 5 on the top surface of the cross beam 3. The scale lines 31 are spaced at intervals from the zero point in the positive and negative directions of the Y direction. Specifically, before the scribing operation, the tool 5 just touching the outer shell of the battery 6 in the Y direction can be used as a reference position, and the first scale value corresponding to the tool 5 at this reference position is recorded. Then, the tool 5 is moved away from the battery 6 in the Y direction, and then the cross beam 3 is moved to a farther position in the X direction to make the tool 5 move away from the battery 6 in the X direction. Immediately afterwards, the tool 5 is moved closer to the zero point in the Y direction to a preset second scale value. Among them, the difference between the first scale value and the second scale value is the depth of scribing the outer shell of the battery 6. Finally, by driving the cross beam 3 to move in the X direction, the tool 5 can scribe the outer shell of the battery 6. In this embodiment, the depth of scribing the outer shell of the battery 6 is preferably about 1 mm. Therefore, the interval of the scale lines 31 in the Y direction is also preferably 1 mm.
[0036] In this embodiment, at least one hollow groove 32 is provided in the cross beam 3. This hollow groove 32 penetrates the cross beam 3 in the vertical direction and extends in the Y direction. The above two cutting tools 5 are vertically inserted into the hollow groove 32. Correspondingly, scale lines 31 are provided on the top surface of the cross beam 3 at adjacent positions of the hollow groove 32, so that when the cutting tool 5 moves along the Y direction in the hollow groove 32, it is convenient to read the position where the cutting tool 5 is located. In addition, a fastening assembly 8 is connected between the cross beam 3 and the cutting tool 5. The fastening assembly 8 is used to clamp both ends of the cross beam 3 in the X direction, so that the cutting tool 5 can be clamped by the two groove walls of the hollow groove 32 together. Through such a design, the cutting tool 5 can be fixed inside the cross beam 3, so that when the cutting tool 5 scribes the outer shell of the battery 6, the torque received by the cross beam 3 can be reduced, and the risk that the guide rail 7 is jammed due to excessive torque on the cross beam 3 can be reduced, ensuring that the cross beam 3 can slide smoothly in the X direction, thereby improving the smoothness of the cutting tool 5 scribing in the X direction. More specifically, in order to further reduce the risk of the guide rail 7 being jammed and further improve the smoothness of the cross beam 3 sliding in the X direction, the width of the cross beam 3 in the X direction is increased in this embodiment. Based on the structural design of the cross beam 3 with a larger width, in order to achieve the purpose that the cutting tool 5 can still be clamped by the two groove walls of the hollow groove 32 together, two hollow grooves 32 are designed in the cross beam 3 of this embodiment. The two hollow grooves 32 are arranged at intervals in the X direction. One hollow groove 32 is used to insert the cutting tool 5, and the other hollow groove 32 is used to place a spacer 9. A hole (not shown in the figure) for the above fastening assembly 8 to pass through needs to be designed on the spacer 9. In this way, when the fastening assembly 8 passes through the cross beam 3 and clamps both ends of the cross beam 3 in the X direction, the purpose that the cutting tool 5 is clamped by the two groove walls in one of the hollow grooves 32 together can be achieved. At this time, the spacer 9 will be clamped by the two groove walls in the other hollow groove 32 together. In addition, preferably, the two cutting tools 5 are placed in different hollow grooves 32.
[0037] In this embodiment, the fastening assembly 8 preferably includes a bolt 81 and a nut 82. A chute 33 is provided on the side surface of the cross beam 3. The chute 33 penetrates the cross beam 3 along the X direction and extends along the Y direction. An installation hole 51 is provided on the tool 5. The bolt 81 sequentially passes through the chute 33 and the installation hole 51 and penetrates outwards relative to the cross beam 3. Moreover, the bolt 81 also needs to pass through the hole positions on the spacer 9, and the nut 82 is threadedly connected to the part of the bolt 81 that penetrates outwards relative to the cross beam 3. After the nut 82 is tightened, the nut 82 and the bolt 81 can jointly clamp both ends of the cross beam 3 along the X direction, thereby achieving the purpose that the tool 5 can be clamped by the two groove walls of the hollow groove 32. The fastening assembly 8 of this structure has the advantages of simple structure and low cost. In addition, the installation hole 51 can also be designed to extend along the vertical Z direction, so as to facilitate the adjustment of the height position of the tool 5. In other embodiments, the height of the jig 2 relative to the base 1 can also be adjusted to adjust the required position of the tool 5 for scribing the outer shell of the battery 6 in the height direction.
[0038] In this embodiment, a downwardly concave first limiting groove 21 and a second limiting groove 22 are provided on the top of the jig 2. Both the first limiting groove 21 and the second limiting groove 22 are used to limit the position of the battery 6. The depths of the first limiting groove 21 and the second limiting groove 22 are preferably 50% to 70% of the height of the battery 6, so as to improve the stability of the battery 6 fixed in the first limiting groove 21 or the second limiting groove 22. By simultaneously providing the first limiting groove 21 and the second limiting groove 22, the requirement of scribing for two postures of the battery 6 can be met. Preferably, the first limiting groove 21 communicates with the second limiting groove 22. The extending direction of the first limiting groove 21 points to the X direction, and the extending direction of the first limiting groove 21 and the extending direction of the second limiting groove 22 are perpendicular to each other. That is, the extending direction of the second limiting groove 22 points to the Y direction, so that the first limiting groove 21 and the second limiting groove 22 jointly form a cross groove structure. When the battery 6 is placed in the first limiting groove 21, the two tools 5 can scribe the outer shell of the battery 6 in the length direction. When the battery 6 is placed in the second limiting groove 22, the outer shell of the battery 6 can be scribed in the width direction. That is, the function of scribing the outer shell of the battery 6 on both the long side and the short side can be realized, so that the entire circumference of the outer periphery of the battery 6 can complete the scribing operation, which is convenient for subsequent disassembly operations on the outer shell of the battery 6, and further improves the efficiency of disassembling the outer shell of the battery 6. In addition, in actual operation, different jigs 2 can be replaced according to different sizes of the battery 6 to meet the purpose of quickly completing the scribing operation for various sizes of the battery 6.

These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way.
