Abstract
Description
Technical Field
[0001] This invention relates to the field of battery manufacturing technology, and in particular to a battery clamp and a rotary liquid injection machine. Background Technology
[0002] Battery electrolyte filling is a crucial step in battery production. To facilitate this process, the battery must be held with its opening facing upwards. When clamping the battery body, it's essential to avoid both over-clamping and allowing the battery to become loose. Over-clamping can damage the battery and make subsequent electrolyte filling difficult or impossible; conversely, incomplete clamping can cause the battery to loosen, compromising its positional accuracy and stability within the battery fixture. Current technology uses multiple clamping protrusions on the clamping plates to prevent over-clamping, creating a gap between the battery body and the clamping plates for easier electrolyte filling. However, these protrusions leave marks (indentations) on the battery surface. Furthermore, when a robotic arm places the battery vertically downwards between the two clamping plates, these protrusions can interfere with the battery, causing uneven or unstable battery placement. Summary of the Invention
[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a battery clamp and a rotary liquid injection machine.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A battery clamp includes a frame, an opening / closing clamp drive mechanism, a support block, a clamping assembly, and a battery support mechanism. The support block is disposed on the bottom wall of the frame and located within the clamping assembly. The opening / closing clamp drive mechanism is installed within the frame. The clamping assembly includes two parallel and oppositely arranged clamping plates. The opening / closing clamp drive mechanism drives the two clamping plates to move closer or further apart. The support block is located between the two clamping plates. At least one clamping plate has a battery support mechanism on its outer side wall. The battery support mechanism includes a fixing seat mounted on the outer side wall of the clamping plate. The system includes a movable plate that is vertically and horizontally positioned between the fixed base and the clamping plate; several suction cups installed on the side of the movable plate near the clamping plate; an elastic element located on the side of the movable plate away from the suction cups and elastically clamped between the movable plate and the fixed base; and a swing rod rotatably connected to the fixed base in the middle. The inner end of the swing rod is hinged to the bottom of the movable plate, and the outer end of the swing rod is used to abut against the inner side wall of the frame. The clamping plate has several embedding holes, and the suction cups are correspondingly set in the embedding holes. The suction cups can be stored in the embedding holes or extend into the clamping assembly.
[0005] Furthermore, the movable plate has a recessed mounting hole on the side near the fixed base, and the fixed base has a recessed lifting guide groove on the side near the movable plate. One end of the elastic element is inserted into the mounting hole, and the other end of the elastic element extends into the lifting guide groove, so that the elastic element can move up and down along the lifting guide groove.
[0006] Furthermore, the inner wall of the frame is equipped with an abutment block, and the outer end of the swing arm abuts against the abutment block.
[0007] Furthermore, there is a space for movement between the fixed base and the clamping plate, and the movable plate is located within the space for movement.
[0008] Furthermore, the battery clamp also includes a lifting drive mechanism mounted on the bottom wall of the frame for driving the lifting of the support block.
[0009] Furthermore, there are two clamping components, which are arranged in parallel. The opening and closing clamping drive mechanism is used to drive the two clamping components to open or close synchronously, and the lifting drive mechanism is located between the two clamping components.
[0010] Furthermore, the fixing base includes an upper fixing plate and a lower fixing plate located below the upper fixing plate and installed on the outer side wall of the clamping plate. A connecting block protrudes from the side of the upper fixing plate near the moving plate. The moving plate has a movable hole. The connecting block passes through the movable hole and is installed on the outer side wall of the clamping plate. The moving plate can move up and down and translate relative to the connecting block.
[0011] Furthermore, the bottom of the movable plate is provided with a hinge, the inner end of the swing arm is hinged to the hinge seat via a hinge shaft, the lower fixed plate is provided with a rotating groove, a rotating shaft is installed in the rotating groove, and the middle part of the swing arm is rotatably connected to the rotating shaft.
[0012] Furthermore, the top surface of the support block is recessed with a groove, which is Y-shaped, V-shaped or U-shaped.
[0013] The present invention also provides a rotary liquid injection machine, including the battery clamp described above.
[0014] The beneficial effects of this invention are as follows: In practical applications, the opening and closing clamping drive mechanism drives the two clamping plates of the clamping assembly to move away from each other, so that the two clamping plates open. The inner wall of the frame presses against the outer end of the swing rod, causing the inner end of the swing rod to swing upward and drive the moving plate to move closer to the fixed seat and rise. The moving plate compresses the elastic element, and the suction cup retracts into the embedding hole of the clamping plate. At this time, the transfer robot can place the battery vertically between the two clamping plates, and the support block supports the bottom of the battery. Then, the opening and closing clamping drive mechanism drives the two clamping plates to move closer to each other, and the clamping plates will drive the battery support mechanism to move away from the inner wall of the frame, so that the inner wall of the frame and the fixed seat move together. As the distance between the fixed seats gradually increases, the outer end of the swing arm continuously contacts the inner wall of the frame. The elastic element gradually recovers its elasticity. Under the action of the elastic element's rebound force, the moving plate moves and descends towards the clamping plate, causing the suction cup to extend out of the mounting hole and be positioned inside the clamping assembly to firmly grip the side of the battery body. During the process of the two clamping plates clamping the battery body, the suction cup firmly grips the battery body, thus providing support for the battery body. It should be noted that the two clamping plates do not completely clamp the battery body; the suction cup is needed to firmly grip the battery body to ensure the battery's positional accuracy and stability between the two clamping plates. When it is necessary to remove the battery, the transfer robot first grips the air bag part of the battery. As the opening and closing clamping drive mechanism drives the two clamping plates to gradually open, the inner wall of the frame abuts against and squeezes the outer end of the swing arm, causing the swing arm to swing. This causes the suction cup to retract into the mounting hole of the clamping plate, separating the suction cup from the battery body. The transfer robot can then remove the battery from between the two clamping plates. This invention clamps the battery body with a clamping component while a suction cup holds the battery body tightly. This ensures the battery's positional accuracy and stability without the clamping component clamping the battery body too tightly. The battery will not loosen or shift, nor will it damage the battery body or leave marks on it. It also helps improve the efficiency of subsequent liquid injection. Attached Figure Description

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0022] like Figures 1 to 6 As shown, the present invention provides a battery clamp, which includes a frame 1, an opening and closing clamp driving mechanism 2, a support block 3, a clamping assembly 4, and a battery support mechanism 5. The support block 3 is disposed on the bottom wall of the frame 1 and located within the clamping assembly 4. The opening and closing clamp driving mechanism 2 is installed within the frame 1. The clamping assembly 4 includes two clamping plates 6 arranged parallel and opposite to each other. The opening and closing clamp driving mechanism 2 is used to drive the two clamping plates 6 to move closer or further apart from each other. The support block 3 is located between the two clamping plates 6. At least one clamping plate 6 has a battery support mechanism 5 provided on its outer side wall. The battery support mechanism 5 includes a fixing seat 7 installed on the outer side wall of the clamping plate 6. The system comprises a movable plate 8 positioned between the fixed base 7 and the clamping plate 6, which is vertically and horizontally oriented; several suction cups 9 mounted on the side of the movable plate 8 near the clamping plate 6; an elastic element 10 positioned on the side of the movable plate 8 away from the suction cups 9 and elastically clamped between the movable plate 8 and the fixed base 7; and a swing rod 11 rotatably connected to the fixed base 7 in the middle. The inner end of the swing rod 11 is hinged to the bottom of the movable plate 8, and the outer end of the swing rod 11 is used to abut against the inner sidewall of the frame 1. The clamping plate 6 has several insertion holes 12, and the suction cups 9 are correspondingly arranged in the insertion holes 12. The suction cups 9 can be housed in the insertion holes 12 or extend into the clamping assembly 4. Specifically, the elastic element 10 can be a spring, and the swing rod 11 is obtuse-angled.
[0023] In practical applications, the opening and closing clamping drive mechanism 2 drives the two clamping plates 6 of the clamping assembly 4 to move away from each other, so that the two clamping plates 6 open. The inner wall of the frame 1 presses the outer end of the swing rod 11, causing the inner end of the swing rod 11 to swing upward and drive the moving plate 8 to move and rise closer to the fixed seat 7. The moving plate 8 compresses the elastic element 10, and the suction cup 9 retracts into the embedding hole 12 of the clamping plate 6. At this time, the transfer robot can place the battery vertically between the two clamping plates 6, and the support block 3 supports the bottom of the battery. Then, the opening and closing clamping drive mechanism 2 drives the two clamping plates 6 to move closer to each other. The clamping plates 6 will drive the battery support mechanism 5 to move away from the inner wall of the frame 1, so that the inner wall of the frame 1 is aligned with the fixed seat 7. As the distance between the seats 7 gradually increases, the outer end of the swing arm 11 continues to abut against the inner wall of the frame 1, and the elastic element 10 gradually recovers its elasticity. Under the action of the elastic force of the elastic element 10, the moving plate 8 moves and descends towards the clamping plate 6, so that the suction cup 9 extends out of the embedding hole 12 and is located inside the clamping assembly 4 to clamp the side of the battery body. During the process of the two clamping plates 6 clamping the battery body, the suction cup 9 clamps the battery body to support the battery body. It should be noted that the two clamping plates 6 do not completely clamp the battery body. It is necessary to rely on the suction cup 9 to clamp the battery body to ensure the positional accuracy and stability of the battery between the two clamping plates 6. When the battery needs to be removed, the transfer robot first clamps the air bag part of the battery. As the opening and closing clamping drive mechanism 2 drives the two clamping plates 6 to gradually open, the inner wall of the frame 1 abuts against and squeezes the outer end of the swing rod 11, causing the swing rod 11 to swing, thereby causing the suction cup 9 to retract into the embedding hole 12 of the clamping plate 6. The suction cup 9 separates from the main body of the battery, and the transfer robot can then remove the battery from between the two clamping plates 6.
[0024] In this invention, while the clamping component 4 clamps the main body of the battery, the suction cup 9 firmly sucks the main body of the battery. This allows the clamping component 4 to ensure the positional accuracy and stability of the battery without clamping the main body too tightly. The battery will not loosen or shift, nor will it damage the main body of the battery or leave marks on it. It also helps to improve the efficiency of subsequent liquid injection.
[0025] In this embodiment, the movable plate 8 has a recessed mounting hole 13 on the side near the fixed base 7, and the fixed base 7 has a recessed lifting guide groove 14 on the side near the movable plate 8. One end of the elastic member 10 is inserted into the mounting hole 13, and the other end of the elastic member 10 extends into the lifting guide groove 14, allowing the elastic member 10 to move up and down along the lifting guide groove 14. This structural design facilitates the installation and fixation of the elastic member 10, ensures that the elastic member 10 is continuously clamped between the movable plate 8 and the fixed base 7, and enables the elastic member 10 to move with the movable plate 8.
[0026] In this embodiment, an abutment block 15 is installed on the inner sidewall of the frame 1, and the outer end of the swing rod 11 abuts against the abutment block 15. By abutting against the outer end of the swing rod 11 with the abutment block 15, the inner wall of the frame 1 is prevented from directly contacting the outer end of the swing rod 11, thus avoiding wear on the frame 1. Even if the abutment block 15 is worn, it can be replaced simply by replacing the abutment block 15, making maintenance convenient and cost-effective.
[0027] In this embodiment, there is a movable space between the fixed base 7 and the clamping plate 6, and the movable plate 8 is located within the movable space. This structural design ensures that the movable plate 8 can be raised, lowered, and translated normally, and makes the structure of the fixed base 7, the clamping plate 6, and the movable plate 8 compact.
[0028] In this embodiment, the battery clamp also includes a lifting drive mechanism 16 mounted on the bottom wall of the frame 1 and used to drive the support block 3 to rise and fall. In practical applications, the lifting drive mechanism 16 drives the support block 3 to rise and fall to adjust the initial height position of the support block 3, thereby ensuring support for batteries of different sizes.
[0029] In this embodiment, there are two clamping components 4, which are arranged in parallel. The opening and closing clamping drive mechanism 2 is used to drive the two clamping components 4 to open or close synchronously. The lifting drive mechanism 16 is located between the two clamping components 4. This structural design can clamp two batteries at a time, improving the production efficiency of batteries.
[0030] In this embodiment, the fixing base 7 includes an upper fixing plate 17 and a lower fixing plate 18 located below the upper fixing plate 17 and mounted on the outer side wall of the clamping plate 6. A connecting block 19 protrudes from the side of the upper fixing plate 17 near the moving plate 8. The moving plate 8 has a movable hole 20. The connecting block 19 passes through the movable hole 20 and is mounted on the outer side wall of the clamping plate 6. The moving plate 8 can move up and down and translate relative to the connecting block 19. This structural design realizes the modularity of the fixing base 7, which facilitates the assembly and disassembly of the battery support mechanism 5 and the clamping plate 6, and the movement of the moving plate 8 is stable and reliable.
[0031] In this embodiment, the bottom of the movable plate 8 is provided with a hinge part 21, and the inner end of the swing arm 11 is hinged to the hinge seat via a hinge shaft 22. The lower fixed plate 18 is provided with a rotating groove 23, and a rotating shaft 24 is installed in the rotating groove 23. The middle part of the swing arm 11 is rotatably connected to the rotating shaft 24. This structural design makes the swing arm 11 swing smoothly and reliably.
[0032] In this embodiment, the top surface of the support block 3 is recessed with a groove 25, which is Y-shaped, V-shaped, or U-shaped. In practical applications, the bottom of the battery can be placed in the groove 25, thereby improving the positional accuracy and stability of the support block 3 in supporting the battery.
[0033] The present invention also provides a rotary liquid injection machine, including the battery clamp described above; the rotary liquid injection machine has all the beneficial effects of the battery clamp, which will not be repeated here.
[0034] All technical features in this embodiment can be freely combined according to actual needs.
[0035] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
