Description

Technical Field

[0001] This invention relates to the field of battery casing technology, and more particularly to a scoring mechanism for square aluminum casings. Background Technology

[0002] In the new energy industry, battery casings come in square and cylindrical shapes. The casing houses the battery cells and electrolyte. To ensure battery stability and safety, explosion-proof grooves are machined at the opening of the casing to allow for timely release of pressure changes occurring inside the battery.

[0003] Traditional aluminum shell explosion-proof scoring requires the use of a punch press and a die. The scoring depth is determined based on the burst pressure value. However, when the burst pressure value changes, the scoring tool length needs to be readjusted, which is difficult to adjust and hard to control accurately, easily affecting the processing cycle and quality. In addition, aluminum shell explosion-proof scoring is done on both sides, while punch presses and dies can generally only perform single-sided operations, resulting in low processing efficiency. Summary of the Invention

[0004] One advantage of this invention is that it provides a square aluminum shell scoring mechanism, wherein the position of the fixing plate is adjusted based on the limiting screw until the limiting screw abuts against the fixing base. The scoring blades in the two scoring mechanisms can simultaneously process explosion-proof scoring on both sides of the square aluminum shell at one time, greatly improving the processing efficiency. When the explosion-proof value of the square aluminum shell changes, the limiting screw is rotated to limit the corresponding scoring depth, and a micrometer is rotated for fine adjustment so that the scoring blade can reach the required scoring depth. This allows for faster adaptation to processing scoring with different explosion-proof value requirements, convenient adjustment, further improved processing efficiency, and ensured scoring quality.

[0005] One advantage of this invention is that it provides a square aluminum shell scoring mechanism, wherein the position of the fixing plate and the limit screws and micrometer on the fixing plate can be quickly adjusted by a coarse adjustment cylinder, and the square aluminum shell is positioned correctly by two sets of upper and lower through-beam sensors, thereby ensuring the quality of the scoring process.

[0006] One advantage of this invention is that it provides a square aluminum shell scoring mechanism, wherein the pressure plate is connected to the guide block by a buffer spring on the guide shaft, which can flatten and fix the opening of the square aluminum shell before the scoring knife is used to score, so as to avoid the square aluminum shell from shaking, so as to facilitate the scoring knife to score and ensure the processing accuracy.

[0007] To achieve at least one of the advantages of the present invention, the present invention provides a square aluminum shell scoring mechanism for simultaneously scoring two sides of a square aluminum shell, the square aluminum shell scoring mechanism comprising:

[0008] Base;

[0009] A fixed base, wherein the fixed base is fixedly disposed on the top of the base, and the top of the fixed base is provided with an inner support block, wherein the inner support block extends along the height direction for the square aluminum shell to be fitted on, so as to position and fix the square aluminum shell.

[0010] Two scoring mechanisms are symmetrically arranged on both sides of the fixed base and facing the side of the inner support block. Each scoring mechanism includes a depth adjustment structure and a scoring structure. The depth adjustment structure includes a fixed plate and a limiting screw and a micrometer disposed on the fixed plate. The fixed plate is disposed on the base in a manner that allows it to be relatively close to or away from the fixed base. The limiting screw and the micrometer are both facing the fixed base. The scoring structure includes a scoring knife, which is disposed on the fixed plate in a manner that allows it to be relatively close to or away from the inner support block, so as to simultaneously score both sides of the square aluminum shell on the inner support block.

[0011] According to one embodiment of the present invention, the square aluminum shell scoring mechanism further includes a base, the base being detachably connected to the top of the base, and the bottom of the base being provided with support legs in a support manner.

[0012] According to one embodiment of the present invention, the depth adjustment structure further includes a coarse adjustment cylinder, which is detachably connected to the top of the base and located on the outside of the base.

[0013] According to one embodiment of the present invention, two support rods are symmetrically arranged on the top of the coarse adjustment cylinder. Two sets of through-beam photoelectric sensors are arranged on the upper part of the support rods, and the sensing ends of the two sets of through-beam sensors are 0.08-0.15mm apart in the height direction. After the square aluminum shell is placed in place, the two through-beam photoelectric sensors near the top cannot detect the square aluminum shell, while the two through-beam sensors near the bottom can detect the square aluminum shell.

[0014] According to one embodiment of the present invention, the depth adjustment structure has two limiting screws and two micrometers, and the two limiting screws and the micrometers are symmetrically arranged on the front and rear sides of the fixing plate, wherein the front and rear sides of the fixing plate are the two sides of the fixing plate in the extension and retraction direction of the piston rod.

[0016] According to one embodiment of the present invention, the scoring structure further includes a pressure plate, two guide shafts and a buffer spring. The two guide shafts are symmetrically fixedly embedded in the guide block and extend along the extension and retraction direction of the piston rod of the scoring cylinder. The buffer springs are respectively sleeved on the guide shafts in a clearance fit. The buffer springs are elastically connected between the pressure plate and the guide block in a compressed manner.

The buffer spring is elastically connected between the adapter plate and the clamping plate. The guide block is provided with a through hole that mates with the buffer spring clearance.

[0018] According to one embodiment of the present invention, the inner support block is provided with a guide protrusion extending in the same direction at the top. The guide protrusion includes a first trapezoidal platform, a transition platform and a second trapezoidal platform connected in sequence.

[0025] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0026] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 5 A preferred embodiment of the present invention, a square aluminum shell scoring mechanism, will be described in detail below. The square aluminum shell scoring mechanism is used to simultaneously score two sides of a square aluminum shell 10. The square aluminum shell scoring mechanism includes a base 20, a fixed base 30, and two scoring mechanisms 40. The fixed base 30 is fixedly disposed on the top of the base 20 and extends along the width direction of the base 20. At the same time, an inner support block 31 is provided on the top of the fixed base 30 along the height direction for the square aluminum shell 10 to be fitted, so as to position and fix the square aluminum shell 10.

[0029] Furthermore, two scoring mechanisms 40 are symmetrically arranged on the left and right sides of the fixed base 30, that is, on both sides of the width direction of the fixed base 30. The two scoring mechanisms 40 face the side of the inner support block 31 and include a depth adjustment structure and a scoring structure. The depth adjustment structure includes a fixed plate 41 and a limiting screw 42 and a micrometer 43 disposed on the fixed plate 41. The fixed plate 41 is disposed on the base 20 in a manner that allows it to be relatively close to or away from the fixed base 30. The limiting screw 42 and the micrometer 43 are both directly opposite the fixed base 30. The limiting screw 42 is used to limit a fixed scoring depth position, while the micrometer 43 is used to fine-tune or adjust the scoring depth position. When both are rotated to their respective positions, the fixed plate 41 is moved closer to the fixed base 30, causing the limiting screw 42 to abut against the surface of the fixed base 30, thereby limiting the fixed plate 41. Additionally, the scoring structure includes a scoring blade 44, wherein the scoring blade 44 is arranged in a manner that allows it to be relatively close to or away from the fixed base 30. The inner support block 31 is positioned on the fixed plate 41 so that the square aluminum shell 10 on both sides of the inner support block 31 is simultaneously scored. In this way, when the limiting screw 42 abuts against the fixed base 30, the position of the fixed plate 41 is precisely fixed. At this time, by controlling the carving knife 44 to approach the inner support block 31, the scoring on both surfaces of the square aluminum shell 10 can be processed simultaneously by the carving knife 44 on both sides without the need for flipping and secondary processing, which greatly improves the work efficiency. When the explosion-proof value of the square aluminum shell 10 to be processed changes, the limiting screw 42 and micrometer 43 are rotated and adjusted according to the current explosion-proof value information. If the explosion-proof value is greater than the current value, the scoring depth is adjusted to be shallower; if the explosion-proof value is less than the current value, the scoring depth is adjusted to be deeper. In this way, multiple square aluminum shells 10 with different explosion-proof value requirements can be processed flexibly, and the length of the carving knife does not need to be readjusted, which can further improve the work efficiency and avoid the risk of inaccurate extension distance of the carving knife 44 when readjusting it.

[0030] In one embodiment, the square aluminum shell scoring mechanism further includes a base 50, and the base 20 is detachably connected to the top of the base 50 to facilitate the transfer and transportation of the square aluminum shell scoring mechanism. In addition, the bottom of the base 50 is provided with support legs 51 to ensure the levelness of the base 20 and to prevent water, other contaminants, etc. from damaging the accuracy and service life of the scoring mechanism.

[0031] More preferably, the depth adjustment structure further includes a coarse adjustment cylinder 45. The coarse adjustment cylinder 45 is detachably connected to the top of the base 50 and located on the outside of the base 20. The piston rod of the coarse adjustment cylinder 45 is fixedly connected to the fixing plate 41, used to drive the fixing plate 41 to move in a specific direction. Guide structures are correspondingly provided at the bottom of the fixing plate 41 and the top of the base 20, and the extension direction of the guide structures is the same as the extension and retraction direction of the piston rod. This allows the coarse adjustment cylinder 45 to guide the fixing plate 41, ensuring the accuracy of the moving direction of the fixing plate 41, and thus ensuring the machining accuracy of the engraving. The guiding structure may include a slider at the bottom of the fixed plate 41 and a guide rail 21 at the top of the base 20, wherein the slider and the guide rail are slidably engaged. In addition, since the limiting screw 42 and the micrometer 43 are both set on the fixed plate 41, the limiting screw 42 and the micrometer 43 can be quickly moved into place by the coarse adjustment cylinder 45, and then fine adjustment can be made by the limiting screw 42 and the micrometer 43. This can further reduce the scoring processing time of multiple square aluminum shells 10 with different burst values.

[0032] More preferably, the top of the coarse adjustment cylinder 45 is symmetrically provided with two support rods 46 along the width direction of the base. The upper part of each support rod 46 is provided with two sets of through-beam photoelectric sensors 47, and the gap between the sensing ends of the two sets of through-beam sensors 47 in the height direction is 0.08-0.15mm. After the square aluminum shell 10 is placed in position, the two through-beam photoelectric sensors 47 near the top cannot detect the square aluminum shell 10, while the two through-beam sensors 47 near the bottom can detect it. Based on the basic principle of two points forming a line and the gap between the sensing ends of the two sets of through-beam sensors 47 in the height direction, only when the upper through-beam photoelectric sensor 47 cannot detect the square aluminum shell 10 and the lower through-beam photoelectric sensor 47 detects it can it be said that the square aluminum shell 10 is placed in position. If either condition is not met, it indicates that the square aluminum shell 10 is placed crookedly or not in position, thus further ensuring the quality of the scoring process on the square aluminum shell.

[0033] When the square aluminum shell 10 is detected to be misplaced or not in place, a signal is sent to the controller. The controller then controls the engraving knife 44 to stop working, which in turn controls the subsequent engraving cylinder 48 to stop working. This avoids waste of raw materials due to incorrect engraving position, thus saving resources and costs.

[0034] In one embodiment, the depth adjustment structure has two limiting screws 42 and two micrometers 43, and the two limiting screws 42 and two micrometers 43 are symmetrically arranged on the front and rear sides of the fixing plate 41. The front and rear sides of the fixing plate 41 are the two sides of the fixing plate 41 in the extension and retraction direction of the piston rod. In this way, the limiting screws 42 and micrometers 43 can be adjusted simultaneously on the front and rear sides, and the machining accuracy of the engraving on the square aluminum shell 10 is ensured based on the principle of two points in a line.

[0035] In one embodiment, the scoring structure further includes a scoring cylinder 48 and a guide block 49, wherein the scoring cylinder 48 is fixedly mounted on the top of the base 20, and the piston rod of the scoring cylinder 48 faces the inner support block 31, wherein the guide block 49 is fixedly connected to the piston rod of the scoring cylinder 48 so that it can be driven by the scoring cylinder 48 to move in a specific direction, and the scoring knife 44 is fixedly disposed in the guide block 49, and has a scoring portion protruding from the guide block 49 on the side of the guide block 49 near the inner support block 31, so that after the scoring cylinder 48 drives the guide block 49 into place, the scoring portion is used to process the scoring on the surface of the square aluminum shell 10.

[0036] Considering that although the scoring is performed on both surfaces of the square aluminum shell 10 simultaneously, and the inner support block 31 can also limit and fix the square aluminum shell during the scoring process, there is still a risk that the square aluminum shell 10 may move or wobble slightly at the scoring location, which poses a potential risk to the scoring quality. Therefore, more preferably, the scoring structure also includes a pressure plate 491, two guide shafts 492, and a buffer spring 493. The two guide shafts 492 are symmetrically fixed and embedded in the guide block 49 and extend along the extension and retraction direction of the piston rod of the scoring cylinder 48. The buffer springs 493 are respectively sleeved in a clearance fit. On the guide shaft 492, the buffer spring 493 is elastically connected between the clamping plate 491 and the guide block 49 under pressure. The clamping plate 41 is provided with a clearance channel for the directional movement of the engraving knife 44. In this way, before the engraving knife 44 contacts the square aluminum shell 10, the clamping plate 491 will first contact the square aluminum shell 10. Then the engraving cylinder 48 will move further against the rebound force of the buffer spring 493 until the engraving knife 44 reaches the appropriate position to make engravings. During engraving, the clamping plate 491 always remains in a state of pressing the square aluminum shell 10 on both sides, which can greatly improve the stability of the square aluminum shell 10 and thus ensure the processing quality of the engravings.

[0037] More preferably, the piston rod of the scoring cylinder 48 is connected to the guide block 49 via an adapter plate 481. The adapter plate 481 abuts against or is partially embedded in the surface of the guide block 49, and the guide shaft 492 is vertically fixed to the adapter plate 481. The buffer spring 493 is elastically connected between the adapter plate 481 and the clamping plate 491. The guide block 49 is provided with a through hole that fits loosely with the buffer spring 493. Thus, by using the adapter plate 481, the buffer spring 493 can be provided with a maximum elastic extension and contraction space, improving its fatigue resistance and extending its service life. Furthermore, the detachable connection formed by the adapter plate 481 facilitates the replacement and maintenance of the buffer spring 493.

[0038] In one embodiment, the inner support block 31 is provided with a guide protrusion 32 extending in the same direction at the top. The guide protrusion 32 includes a first trapezoidal platform 321, a transition platform 322, and a second trapezoidal platform 323 connected in sequence. The first trapezoidal platform 321 is connected to the inner support block 31. The outer diameter of the first trapezoidal platform 321 and the second trapezoidal platform 323 gradually decreases from one end near the inner support block 31 to the opposite end. Thus, a stepped guide structure can be formed by the first trapezoidal platform 321, the transition platform 322, and the second trapezoidal platform 323, so that the square aluminum shell 10 can be placed in place more quickly and accurately.

[0039] It should be noted that the terms "first" and "second" used in this invention are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
