[0002] With the popularization of new energy vehicles and portable electronic devices, lithium batteries, as important energy storage devices, have received widespread attention for their performance and safety. When designing lithium batteries, the choice of casing material is crucial. It not only needs to protect the internal electrochemical components and structure of the battery, but also needs to have properties such as high temperature resistance, corrosion resistance, vibration resistance, and extrusion resistance. Among many materials, aluminum casing has become the first choice for lithium battery casings due to its unique advantages. Aluminum alloy casing is a protective casing for equipment made of aluminum alloy. It is mainly divided into two categories: aluminum profile casing and aluminum die-cast casing. It has high strength, electrical conductivity, thermal conductivity, and corrosion resistance. Its application fields cover electronic equipment, new energy vehicles, medical devices, instruments and meters, etc.

[0003] During the processing of aluminum alloy casings for lithium batteries, the lack of corresponding guiding and anti-deviation components during batch drilling of the aluminum alloy casings can easily lead to deviation during drilling. Furthermore, due to the characteristics of aluminum alloys, such as low strength, good plasticity, and excellent thermal conductivity, problems such as tool sticking, burrs, and insufficient hole diameter accuracy are prone to occur during drilling. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic drilling device for aluminum alloy casings of lithium batteries, which solves the problem of casing misalignment during drilling.

A wedge block is fixedly installed at the end of the positioning rod to cooperate with the wedge block. The anti-deviation plate is provided with a channel for the positioning rods to move.

[0009] Preferably, a trapezoidal block is fixedly installed on the side of the second wedge block that is in contact with the first wedge block, and the trapezoidal block is slidably disposed within a trapezoidal groove opened on the second wedge block. Preferably, a top rod is fixedly installed at the bottom of the wedge block, the bottom end of the top rod slides through the outer wall of the mounting box and extends to the outside of the mounting box, and the bottom end of the top rod is provided with a protruding contact part. An elastic element is installed on the side of the conveyor frame opposite to the top rod, and a contact plate is installed at the top of the elastic element.

[0010] Preferably, a drive motor is fixedly installed at the bottom of the movable support block, and a rotating disk is rotatably installed at the bottom end of the movable support block. The rotating disk is fixedly connected to the output shaft of the drive motor. A drive rod is installed on the side of the rotating disk, and a guide frame is slidably sleeved on the outer surface of the drive rod. The guide frame is fixedly installed on the support plate.

[0011] Preferably, the rotating disk has a mounting groove on its side, and a drive push rod is fixedly installed on the inner wall of the mounting groove. A slider is fixedly installed at the output end of the drive push rod, and the end of the drive rod is fixedly connected to the slider.

[0012] Preferably, two guide rods are fixedly installed at the bottom of the movable support block, and movable blocks are fixedly installed at both ends of the guide frame, with the movable blocks slidably disposed on the outer surface of the guide rods on the same side.

[0013] Preferably, the chip removal mechanism includes a dust collection box fixedly installed on a movable support block, a dust pump fixedly installed on the movable support block, an air extraction pipe of the dust pump penetrating the outer wall of the dust collection box and extending into the interior of the dust collection box, a multi-port pipe provided on the side of the dust collection box, an air outlet pipe of the multi-port pipe penetrating the outer wall of the dust collection box and extending into the interior of the dust collection box, and multiple air inlets of the multi-port pipe being fixed with flexible hoses, the flexible hoses being fixed to a support plate and having a dust extraction head installed at the bottom end of the flexible hose.

[0014] Preferably, a filter screen is slidably installed on the dust collection box, and the filter screen is located between the air outlet pipe of the multi-port pipe and the air extraction pipe of the dust pump.

[0015] Working principle: Place the shell to be drilled on the conveyor belt, control the start of the electric push rod, the electric push rod drives the adjustment plate to move, the movement of the adjustment plate can drive the sliding rod to slide inside the strip slide, so that the sliding rods on both sides are closer to each other, the movement of the sliding rod drives the moving plate to move synchronously, the movement of the moving plate drives the anti-deviation plate to move through the connecting frame, so that the anti-deviation plates on both sides are closer to each other to limit the left and right sides of the shell. The electric conveyor roller is opened to realize the conveyor belt conveying operation. When the outer shell is conveyed to the bottom of the electric drill rod, the drive cylinder is controlled to drive the fixed frame to move downward. The movement of the fixed frame drives the front and rear movement modules, the lateral movement module and the mounting box to move up and down synchronously. The position of the moving block is adjusted by the front and rear movement modules and the lateral movement module, and then the moving block drives the electric drill rod to move, thereby adjusting the position of the electric drill rod. As the mounting box moves downward, it drives the top rod downward synchronously, bringing it into contact with the contact plate. Simultaneously, under the action of the elastic element, the contact plate is driven upward. The upward movement of the contact plate drives the top rod upward synchronously, which in turn drives the wedge block to move upward. When the wedge block moves upward, the two wedge blocks move closer to each other under the action of the inclined surface of the wedge block and the trapezoidal slider. The movement of the wedge blocks moves the positioning rod synchronously, thereby adjusting the position of the positioning rods on both sides and limiting the front and rear parts of the outer shell. The control starts the drive motor, which drives the rotating disk to rotate. The rotation of the rotating disk drives the guide frame to move up and down through the drive rod. The movement of the guide frame drives the support plate to move synchronously. Through the support plate, the bottom electric drill rod can move up and down synchronously, thereby realizing the drilling work on the shell. The electric drill rod reciprocates during the drilling process to perform continuous retraction. The control push rod is activated, causing the slider to slide up and down inside the mounting slot. The movement of the slider causes the drive rod to move, thereby adjusting the position of the drive rod and the movement position of the support plate and the electric drill rod, as well as the drilling depth. When performing semi-punching work on the positioning hole, the rotating disk and the drive push rod drive the electric drill rod to move up and down reciprocally. At the same time, the drive push rod works in conjunction with the rotating disk to adjust the position of the drive rod, thereby adjusting the drilling depth of the electric drill rod. During the drilling process, a dust pump is used to process the generated debris, which is then drawn into the dust collection box through the dust extraction head and hose. The gas is then filtered through a filter screen and discharged, completing the debris collection process.

[0016] This invention provides an automatic hole-opening device for the aluminum alloy casing of lithium batteries. It has the following beneficial effects: 1. This invention utilizes a conveyor belt, an anti-deviation plate, a front-to-back motion module, a lateral motion module, a movable support block, an opening mechanism, and a chip removal mechanism. The conveyor belt transports the outer casing, the anti-deviation plate guides the casing to prevent deviation during transport, and the front-to-back motion module and lateral motion module work together to adjust the position of the opening mechanism to meet the opening requirements at different locations. Simultaneously, the chip removal mechanism collects and removes generated debris in a timely manner to prevent debris accumulation and the formation of chip build-up.

[0017] 2. This invention, by setting up a positioning rod, a mounting box, an elastic element two, a wedge block one, and a wedge block two, utilizes the up-and-down movement of wedge block one to cause the two wedge blocks two to move closer or further apart under the action of the inclined surface of wedge block one. The movement of wedge block two drives the positioning rod to move synchronously, thereby adjusting the position of the positioning rods on both sides. This is used to limit the front and rear parts of the outer shell and to center and align the outer shell, facilitating the alignment for opening work. No additional adjustment or fixing of the outer shell position by the operator is required, improving the convenience of the work.

[0018] 3. This invention, by setting up a drive motor, a rotating disk, a drive rod, and a guide frame, utilizes the drive motor to drive the rotating disk to rotate. The rotation of the rotating disk drives the guide frame to move up and down via the drive rod. The movement of the guide frame drives the support plate to move synchronously. Through the support plate, the bottom electric drill rod can move up and down synchronously, thereby realizing the drilling work on the shell. The electric drill rod reciprocates during the drilling process, performing continuous retraction, which facilitates the removal of chips, avoids damage to the electric drill rod or the shell, and ensures the continuity of processing.

[0019] 4. This invention, by setting up a drive push rod and a slider, uses the drive push rod to drive the slider to slide up and down inside the mounting groove. The movement of the slider will drive the drive rod to move, thereby adjusting the position of the drive rod and the movement position of the support plate and the electric drill rod, as well as the drilling depth. When performing semi-punching work of the positioning hole, the electric drill rod is driven to move up and down reciprocally by the rotating disk and the drive push rod. At the same time, it cooperates with the drive push rod to adjust and change the position of the drive rod, thereby adjusting the drilling depth of the electric drill rod. At the same time, the electric drill rod retracts once every 2-3 times the hole diameter depth to remove chips and avoid repeated friction and adhesion of chips in the hole to form built-up edge.

[0020] 5. This invention, by setting up a dust collection box, a dust pump, a hose, and a dust extraction head, utilizes the dust pump to process the generated debris during the drilling process. The debris is then collected and processed by passing through the dust extraction head and hose into the dust collection box, thus preventing debris from remaining inside the hole and causing scratches on the hole wall or drill bit jamming and breakage.

[0024] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an automatic hole-opening device for aluminum alloy shells of lithium batteries, including a processing base 1. A conveying mechanism 2 is installed on the surface of the processing base 1. The conveying mechanism 2 includes a conveyor frame 201 fixed on the surface of the processing base 1. A conveyor belt 202 is installed on the conveyor frame 201 via an electric conveying roller. A plurality of connecting frames 204 are slidably arranged on the conveyor frame 201. Anti-deviation plates 203 are fixed to the ends of the plurality of connecting frames 204 on the same side. The anti-deviation plates 203 are slidably arranged on the surface of the conveyor belt 202. A support frame 3 is installed on the processing base 1. A drive cylinder 4 is fixedly installed on the support frame 3. The support frame 3 is provided with a position adjustment mechanism 5 for adjusting the position of the opening mechanism 6. The position adjustment mechanism 5 includes a fixed frame 501 fixedly installed on the output end of the drive cylinder 4. Two front and rear motion modules 502 are installed at the bottom of the fixed frame 501. A transverse motion module 503 is installed between the two front and rear motion modules 502. A movable support block 504 is provided on the transverse motion module 503. The opening mechanism 6 is installed on the movable support block 504. The drilling mechanism 6 includes a support plate 607 disposed below the movable support block 504, an electric drill rod 608 mounted on the support plate 607, and a chip removal mechanism 8 for use in conjunction with the drilling mechanism 6 on the movable support block 504.

[0025] By setting up a conveyor belt 202, an anti-deviation plate 203, a front-to-back motion module 502, a lateral motion module 503, a moving support block 504, an opening mechanism 6, and a chip removal mechanism 8, the conveyor belt 202 is used to transport the outer casing. The anti-deviation plate 203 guides the outer casing to prevent it from shifting during transport. The front-to-back motion module 502 and the lateral motion module 503 work together to adjust the position of the opening mechanism 6 to meet the opening requirements at different positions. At the same time, the chip removal mechanism 8 can collect and remove the generated debris in a timely manner to prevent the accumulation of debris and the formation of chip build-up.

[0026] For details, please refer to the appendix. Figure 3 and attached Figure 6 An electric push rod 207 is fixedly installed inside the processing base 1, and an adjustment plate 205 is fixedly installed at the output end of the electric push rod 207. Two strip slides are opened on the adjustment plate 205 and the two strip slides are arranged in a figure-eight shape. A movable plate 208 is fixedly installed at the end of multiple connecting frames 204 on the same side. A sliding rod 206 is installed at the bottom of the movable plate 208 and is slidably arranged inside the strip slide on the same side.

[0027] By setting up an electric push rod 207, an adjusting plate 205, a moving plate 208, and a sliding rod 206, the electric push rod 207 drives the adjusting plate 205 to move. The movement of the adjusting plate 205 drives the sliding rod 206 to slide inside the strip track, so that the sliding rods 206 on both sides move closer or further apart. The movement of the sliding rod 206 drives the moving plate 208 to move synchronously. The movement of the moving plate 208 drives the anti-deviation plate 203 to move through the connecting frame 204, thereby adjusting the distance between the anti-deviation plates 203 on both sides. This allows it to be used with shells of different specifications, thus improving its applicability.

[0028] For details, please refer to the appendix. Figure 5 - Appendix Figure 7 The bottom end of the fixed frame 501 is provided with a centering positioning mechanism 7. The centering positioning mechanism 7 includes two positioning rods 706 and two mounting boxes 701 fixedly installed at the bottom end of the fixed frame 501. The two ends of the positioning rods 706 are respectively slidably arranged inside the two mounting boxes 701. The wedge block 702 is installed inside the mounting box 701 through the elastic element 703. The end of the positioning rod 706 is fixedly installed with a wedge block 705 that cooperates with the wedge block 702. The anti-deviation plate 203 has a channel for the positioning rods 706 to move.

[0029] By setting up positioning rods 706, mounting box 701, elastic element 2 703, wedge block 1 702, and wedge block 2 705, the up-and-down movement of wedge block 1 702 causes the two wedge blocks 2 705 to move closer or further apart under the action of the inclined surface of wedge block 1 702. The movement of wedge block 2 705 drives the positioning rods 706 to move synchronously, thereby adjusting the position of the positioning rods 706 on both sides. This is used to limit the front and rear parts of the outer shell and to center and align the outer shell, facilitating the opening work. No additional adjustment or fixing of the outer shell position by the operator is required, improving the convenience of the work.

[0030] For details, please refer to the appendix. Figure 7 A trapezoidal block 707 is fixedly installed on the side of wedge block 2 705 that is in contact with wedge block 1 702. The trapezoidal block 707 is slidably disposed in the trapezoidal groove opened on wedge block 2 705.

[0031] By setting trapezoidal block 707 and allowing it to slide inside the trapezoidal groove, it is possible to ensure that the inclined surface of wedge block 2 is always in contact with the inclined surface of wedge block 1 702, thereby preventing wedge block 2 705 from detaching and falling off during operation.

[0032] For details, please refer to the appendix. Figure 3 Appendix Figure 6 and attached Figure 7 A top rod 704 is fixedly installed at the bottom of the wedge block 702. The bottom end of the top rod 704 slides through the outer wall of the mounting box 701 and extends to the outside of the mounting box 701. The bottom end of the top rod 704 is provided with a protruding contact part. An elastic element 209 is installed on the side of the conveyor frame 201 in front of the top rod 704. A contact plate 210 is installed at the top of the elastic element 209.

[0033] By setting up a top rod 704, an elastic element 209, and a contact plate 210, as the mounting box 701 moves downward, it will drive the top rod 704 downward synchronously, so that the top rod 704 contacts the contact plate 210. At the same time, under the action of the elastic element 209, the contact plate 210 will be driven to move upward. The upward movement of the contact plate 210 will drive the top rod 704 upward synchronously, and then the top rod 704 will drive the wedge block 702 to move upward. The wedge block 705 will bring the positioning rods 706 on both sides closer to each other, thereby automatically achieving the centering positioning of the outer shell.

[0034] For details, please refer to the appendix. Figure 8 - Appendix Figure 10A drive motor 609 is fixedly installed at the bottom of the movable support block 504, and a rotating disk 601 is rotatably installed at the bottom end of the movable support block 504. The rotating disk 601 is fixedly connected to the output shaft of the drive motor 609. A drive rod 604 is installed on the side of the rotating disk 601. A guide frame 605 is slidably sleeved on the outer surface of the drive rod 604. The guide frame 605 is fixedly installed on the support plate 607.

[0035] By setting up a drive motor 609, a rotating disk 601, a drive rod 604, and a guide frame 605, the drive motor 609 drives the rotating disk 601 to rotate. The rotation of the rotating disk 601 drives the guide frame 605 to move up and down through the drive rod 604. The movement of the guide frame 605 drives the support plate 607 to move synchronously. Through the support plate 607, the bottom electric drill rod 608 moves up and down synchronously, thereby realizing the drilling work of the shell. The electric drill rod 608 reciprocates during the drilling process to perform continuous tool retraction, which facilitates the removal of chips, avoids damage to the electric drill rod 608 or the shell, and ensures the continuity of processing.

[0036] For details, please refer to the appendix. Figure 10 The rotating disk 601 has a mounting groove on its side, and a drive push rod 602 is fixedly installed on the inner wall of the mounting groove. A slider 603 is fixedly installed on the output end of the drive push rod 602, and the end of the drive rod 604 is fixedly connected to the slider 603.

[0037] By setting up a drive push rod 602 and a slider 603, the drive push rod 602 drives the slider 603 to slide up and down inside the mounting groove. The movement of the slider 603 will drive the drive rod 604 to move, thereby adjusting the position of the drive rod 604 and the movement position of the support plate 607 and the electric drill rod 608, as well as the drilling depth. When performing semi-punching work of the positioning hole, the rotating disk 601 and the drive push rod 602 drive the electric drill rod 608 to move up and down reciprocally. At the same time, in coordination with the drive push rod 602, the position of the drive rod 604 is adjusted and changed, thereby adjusting the drilling depth of the electric drill rod 608. At the same time, the electric drill rod 608 retracts once every 2-3 times the hole diameter depth to remove chips and avoid repeated friction and adhesion of chips in the hole to form built-up edge.

[0038] For details, please refer to the appendix. Figure 9 and attached Figure 10 Two guide rods 606 are fixedly installed at the bottom of the movable support block 504, and movable blocks 610 are fixedly installed at both ends of the guide frame 605. The movable blocks 610 are slidably disposed on the outer surface of the guide rods 606 on the same side.

[0039] By setting a guide rod 606 and a moving block 610, the moving block 610 slides up and down on the outer surface of the guide rod 606. The movement of the moving block 610 drives the guide frame 605 to move synchronously, which is used to limit and guide the guide frame 605 and avoid the problem of the guide frame 605 deviating during the operation.

[0040] For details, please refer to the appendix. Figure 10 The chip removal mechanism 8 includes a dust collection box 801 fixedly installed on a movable support block 504. A dust pump 803 is fixedly installed on the movable support block 504. The suction pipe of the dust pump 803 passes through the outer wall of the dust collection box 801 and extends into the interior of the dust collection box 801. A multi-port pipe 804 is provided on the side of the dust collection box 801. The air outlet pipe of the multi-port pipe 804 passes through the outer wall of the dust collection box 801 and extends into the interior of the dust collection box 801. Multiple air inlets of the multi-port pipe 804 are fixed with hoses 805. The hoses 805 are fixed on the support plate 607 and a dust extraction head 806 is installed at the bottom of the hoses 805.

[0041] By setting up a dust collection box 801, a dust pump 803, a hose 805, and a dust extraction head 806, the dust pump 803 can process the generated debris during the drilling process. The debris is then collected inside the dust collection box 801 through the dust extraction head 806 and the hose 805, thus preventing debris from remaining inside the hole and causing scratches on the hole wall or drill bit jamming and breakage.

[0042] For details, please refer to the appendix. Figure 10 A filter screen 802 is slidably installed on the dust collection box 801. The filter screen 802 is located between the air outlet pipe of the multi-port pipe 804 and the air extraction pipe of the dust pump 803.

[0043] By setting up filter 802, the debris is filtered and isolated, which facilitates subsequent processing and prevents the debris from being directly discharged into the working environment, thus avoiding any impact on the working environment and the health of the staff.

[0044] Working principle: The housing to be drilled is placed on the conveyor belt 202. The electric push rod 207 is activated. The electric push rod 207 drives the adjusting plate 205 to move. The movement of the adjusting plate 205 drives the sliding rod 206 to slide inside the strip slide, so that the sliding rods 206 on both sides move closer to each other. The movement of the sliding rod 206 drives the moving plate 208 to move synchronously. The movement of the moving plate 208 drives the anti-deviation plate 203 to move through the connecting frame 204, so that the anti-deviation plates 203 on both sides move closer to each other to limit the left and right sides of the housing. The opening of the electric conveyor roller is controlled to realize the conveying operation of the conveyor belt 202. When the outer shell is conveyed to the bottom of the electric drill rod 608, the drive cylinder 4 is controlled to drive the fixed frame 501 to move downward. The movement of the fixed frame 501 drives the front and rear movement module 502, the lateral movement module 503 and the mounting box 701 to move up and down synchronously. The position of the moving block 504 is adjusted by the front and rear movement module 502 and the lateral movement module 503, and then the moving block 504 drives the electric drill rod 608 to move, thereby adjusting the position of the electric drill rod 608. As the mounting box 701 moves downward, it drives the top rod 704 downward synchronously, causing the top rod 704 to contact the contact plate 210. At the same time, under the action of the elastic element 209, the contact plate 210 is driven to move upward. The upward movement of the contact plate 210 drives the top rod 704 upward synchronously, which in turn drives the wedge block 702 to move upward. When the wedge block 702 moves upward, the two wedge blocks 705 approach each other under the action of the inclined surface of the wedge block 702 and the trapezoidal slider 603. The movement of the wedge blocks 705 drives the positioning rod 706 to move synchronously, thereby adjusting the position of the positioning rods 706 on both sides and limiting the front and rear parts of the outer shell. The drive motor 609 is activated, which drives the rotating disk 601 to rotate. The rotation of the rotating disk 601 drives the guide frame 605 to move up and down via the drive rod 604. The movement of the guide frame 605 drives the support plate 607 to move synchronously. Through the support plate 607, the bottom electric drill rod 608 can move up and down synchronously, thereby realizing the drilling work on the shell. The electric drill rod 608 reciprocates during the drilling process to perform continuous retraction. The control push rod 602 is activated, causing the slider 603 to slide up and down inside the mounting slot. The movement of the slider 603 causes the drive rod 604 to move, thereby adjusting the position of the drive rod 604 and the movement position and drilling depth of the support plate 607 and the electric drill rod 608. When performing semi-punching work of the positioning hole, the rotating disk 601 and the drive push rod 602 drive the electric drill rod 608 to move up and down reciprocally. At the same time, in coordination with the drive push rod 602, the position of the drive rod 604 is adjusted and changed, thereby adjusting the drilling depth of the electric drill rod 608. During the drilling process, the dust pump 803 can process the generated debris, which is then passed through the dust extraction head 806 and the hose 805 into the dust collection box 801. The gas is filtered and discharged through the filter screen 802, thus completing the collection and processing of the debris.
