Description

Technical Field

[0001] This utility model relates to the technical field of cylindrical battery positioning mechanisms, and in particular to a secondary positioning mechanism for cylindrical batteries. Background Technology

[0002] Cylindrical batteries are a type of lithium-ion battery characterized by their cylindrical shape. Large cylindrical batteries are considered the mainstream technology due to their advantages in energy density, safety, and fast charging. Their applications have expanded from new energy vehicles to energy storage and low-altitude industries. This secondary positioning mechanism is designed for use in the semi-automatic bottom welding process station to assist cylindrical batteries in positioning. Its main function is to perform secondary positioning and fine positioning after the cylindrical battery cells are manually placed. The positioning accuracy and speed of this station have a significant impact on the battery's safety performance and working efficiency. The existing semi-automatic station for cylindrical batteries only uses a limiting slot and a magnetic positioning seat for direct placement during the placement process, without automatic correction function in case of manual placement of the material. Therefore, this utility model proposes a secondary positioning mechanism for cylindrical batteries to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing semi-automatic cylindrical battery workstations, which only provide a limiting slot and magnetic positioning seat for direct placement during the placement process, without automatically correcting deviations when manually placing the material. Therefore, this invention proposes a secondary positioning mechanism for cylindrical batteries.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A secondary positioning mechanism for a cylindrical battery includes a base, and the positioning mechanism further includes... The system includes a correction mechanism and a clamping mechanism, wherein the clamping mechanism cooperates with the base. The support mechanism includes: a first electric push rod and a placement plate; The first electric actuator is fixedly installed on the top of the base, and the placement plate is fixedly installed on the top of the output shaft of the first electric actuator.

[0005] As a preferred embodiment of the present invention, the correction mechanism includes: two bonding frames, two driving rods, a connecting rod, and a second electric push rod; Both bonding frames are rotatably connected to the placement plate. Two drive rods are rotatably connected to the two bonding frames and the connecting rod, respectively. The second electric push rod is fixedly connected to the placement plate, and the output shaft of the second electric push rod is fixedly connected to the connecting rod.

[0006] Furthermore, the correction mechanism uses a second electric push rod to drive the connecting rod, which in turn drives the two bonding frames to rotate, thereby achieving automatic centering and correction of the battery. This allows the battery to quickly return to its predetermined position. The structure is compact, the operation is reliable, and it reduces subsequent processing problems caused by placement deviations.

[0007] As a preferred embodiment of the present invention, the clamping mechanism includes: two clamps, a third electric push rod, a fixed rod, a pressing rod, a sliding rod, and a pushing rod; Both clamps are slidably connected to the right side of the base. The third electric push rod is fixedly installed on the right side of the base. The clamp located on the right side is fixedly connected to the fixed rod. The fixed rod is rotatably connected to the push rod. The push rod is rotatably connected to the sliding rod. The sliding rod is slidably connected to the right side of the base. The sliding rod is rotatably connected to the push rod.

[0008] Furthermore, the clamping mechanism drives the clamp and fixing rod located on the right side to move to the left via a third electric push rod. This allows the fixing rod to press the push rod, which in turn presses the sliding rod to move downwards. The sliding rod then pushes the push rod, which in turn pushes the clamp located on the left side to move to the right. This causes the two clamps to move towards or away from each other along the horizontal slide groove, achieving flexible clamping and release of the battery. This provides secondary correction and positioning for the cylindrical battery. The protective pad protects the battery surface, preventing scratches and enhancing the stability and safety of the clamping.

[0009] As a preferred embodiment of this utility model, a horizontal sliding groove is provided on the right side of the base, and both clamps are slidably connected to the inner wall of the horizontal sliding groove.

[0010] Furthermore, the horizontal groove provides precise guidance for the fixture, ensuring that the two fixtures maintain horizontal and synchronous movement, avoiding jamming, and improving the accuracy and reliability of clamping and positioning.

[0011] As a preferred embodiment of this utility model, a vertical groove is provided on the right side of the base, and the sliding rod is slidably connected to the inner wall of the vertical groove.

[0012] Furthermore, the vertical groove provides a stable vertical movement track for the sliding rod, ensuring the smooth operation of the actuating rod transmission mechanism and ensuring the coordination and consistency of the clamping action.

[0013] As a preferred embodiment of this utility model, protective pads are fixedly installed on the sides of the two clamps that are close to each other.

[0014] Furthermore, the pad is made of flexible material, which provides sufficient clamping force while avoiding damage to the battery surface, protecting the battery's appearance integrity and improving product yield.

[0015] As a preferred embodiment of this utility model, connecting blocks are fixedly installed on the top of the clamp located on the left side and the bottom of the clamp located on the right side. The connecting block located on the left side is rotatably connected to the push rod, and the connecting block located on the right side is fixedly connected to the output shaft of the third electric push rod.

[0016] Furthermore, the design of the connecting block optimizes the force transmission path of the transmission mechanism, making the force of the push rod evenly distributed, improving the smoothness and synchronization of the fixture movement, and ensuring the accuracy of clamping and positioning. Beneficial effects

The correction mechanism uses a second electric push rod to drive the connecting rod, which in turn drives the two bonding frames to rotate, thereby achieving automatic centering and correction of the battery. This allows the battery to quickly return to the predetermined position. The structure is compact, the operation is reliable, and it reduces subsequent processing problems caused by placement deviations. 2. The clamping mechanism drives the clamp and fixing rod located on the right side to move to the left side via the third electric push rod. This allows the fixing rod to press the push rod, which in turn presses the sliding rod to move downwards. The sliding rod then pushes the push rod, which in turn pushes the clamp located on the left side to move to the right. This causes the two clamps to move towards or away from each other along the horizontal slide groove, achieving flexible clamping and release of the battery. This provides secondary correction and positioning for the cylindrical battery. The protective pad protects the battery surface, preventing scratches and enhancing the stability and safety of the clamping. In this invention, by setting up a correction mechanism and a clamping mechanism, which work in conjunction with the base, stable support and position correction of the cylindrical battery are achieved. The first electric push rod in the support mechanism drives the placement plate to rise and fall, adapting to the positioning requirements of batteries of different specifications, improving the adaptability and ease of operation of placement, effectively compensating for the deviation problem that may occur when manually placing materials, and improving the positioning accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0021] Reference Figure 1-4 A secondary positioning mechanism for a cylindrical battery includes a base 1, and the positioning mechanism further includes... The system includes a correction mechanism and a clamping mechanism, with the clamping mechanism cooperating with the base 1. The support mechanism includes: a first electric push rod 2 and a placement plate 3; The first electric push rod 2 is fixedly installed on the top of the base 1, and the placement plate 3 is fixedly installed on the top of the output shaft of the first electric push rod 2.

[0022] With the above structure, by setting up a correction mechanism and a clamping mechanism, in coordination with the base 1, stable support and position correction of the cylindrical battery can be achieved. The first electric push rod 2 in the support mechanism drives the placement plate 3 to rise and fall, adapting to the positioning requirements of batteries of different specifications, improving the adaptability and ease of operation of placement, effectively compensating for the deviation problem that may occur when manually placing materials, and improving the positioning accuracy.

[0023] To correct the deviation of the cylindrical battery on the placement plate 3, the correction mechanism includes: two bonding frames 4, two driving rods 5, a connecting rod 6, and a second electric push rod 7. Both bonding frames 4 are rotatably connected to the placement plate 3. Two driving rods 5 are rotatably connected to the two bonding frames 4 and the connecting rod 6 respectively. The second electric push rod 7 is fixedly connected to the placement plate 3. The output shaft of the second electric push rod 7 is fixedly connected to the connecting rod 6. The correction mechanism uses the second electric push rod 7 to drive the connecting rod 6, and drives the two bonding frames 4 to rotate through the driving rod 5, so as to realize the automatic centering and correction of the battery, so that the battery can quickly return to the predetermined position. The structure is compact, the operation is reliable, and the subsequent processing problems caused by placement deviation are reduced.

[0024] To achieve secondary positioning of the cylindrical battery, the clamping mechanism includes: two clamps 8, a third electric push rod 9, a fixed rod 10, a pressing rod 11, a sliding rod 12, and a pushing rod 13; Both clamps 8 are slidably connected to the right side of the base 1. The third electric push rod 9 is fixedly installed on the right side of the base 1. The clamp 8 located on the right side is fixedly connected to the fixed rod 10. The fixed rod 10 is rotatably connected to the push rod 11. The push rod 11 is rotatably connected to the sliding rod 12. The sliding rod 12 is slidably connected to the right side of the base 1. The sliding rod 12 is rotatably connected to the push rod 13. The clamping mechanism drives the clamp 8 and the fixed rod 10 located on the right side to move to the left through the third electric push rod 9. This allows the fixed rod 10 to press the push rod 11, which in turn presses the sliding rod 12 to move downward. The sliding rod 12 then pushes the push rod 13, which in turn pushes the clamp 8 located on the left side to move to the right. This allows the two clamps 8 to move towards or away from each other along the horizontal sliding groove, achieving flexible clamping and release of the battery. This provides secondary correction and positioning of the cylindrical battery. The protective pad protects the battery surface, preventing scratches and enhancing the stability and safety of the clamping.

[0025] To enable the installation of the clamps 8, a horizontal groove is provided on the right side of the base 1. Both clamps 8 are slidably connected to the inner wall of the horizontal groove. The horizontal groove provides precise guidance for the clamps 8, ensuring that the two clamps 8 maintain horizontal synchronous movement, avoiding jamming, and improving the accuracy and reliability of clamping and positioning.

[0026] To facilitate the installation of the sliding rod 12, a vertical groove is provided on the right side of the base 1. The sliding rod 12 is slidably connected to the inner wall of the vertical groove. The vertical groove provides a stable vertical movement track for the sliding rod 12, ensuring the smooth operation of the transmission mechanism of the actuating rod 11 and ensuring the coordination and consistency of the clamping action.

[0027] To protect the cylindrical battery, protective pads are fixedly installed on the sides of the two clamps 8 that are close to each other. The protective pads are made of flexible material, which provides sufficient clamping force while avoiding damage to the battery surface, protecting the integrity of the battery appearance and improving product yield.

[0028] To drive the clamp 8, connecting blocks are fixedly installed on the top of the clamp 8 located on the left and the bottom of the clamp 8 located on the right. The connecting block located on the left is rotatably connected to the push rod 13, and the connecting block located on the right is fixedly connected to the output shaft of the third electric push rod 9. The setting of the connecting blocks optimizes the force transmission path of the transmission mechanism, makes the force of the push rod evenly distributed, improves the smoothness and synchronization of the movement of the clamp 8, and ensures the accuracy of clamping and positioning.

[0029] The working principle of this utility model is as follows: First, the cylindrical battery is placed on the placement plate 3. A correction mechanism and a clamping mechanism are set up. The correction mechanism uses a second electric push rod 7 to drive the connecting rod 6, which in turn drives the two bonding frames 4 to rotate, achieving automatic centering and correction of the battery. This allows the battery to quickly return to its predetermined position. The structure is compact and the operation is reliable, reducing subsequent processing problems caused by placement deviations. Working in conjunction with the base 1, it provides stable support and position correction for the cylindrical battery. The first electric push rod 2 in the support mechanism drives the placement plate 3 to rise and fall, adapting to the positioning requirements of batteries of different specifications, improving the adaptability of placement and ease of operation. To effectively compensate for potential misalignment issues during manual material feeding and improve positioning accuracy, the clamping mechanism uses a third electric push rod 9 to drive the clamp 8 and fixed rod 10, located on the right side, to move to the left. This allows the fixed rod 10 to press the push rod 11, which in turn presses the sliding rod 12 to move downwards. The sliding rod 12 then pushes the push rod 13, which in turn pushes the clamp 8, located on the left side, to move to the right. This allows the two clamps 8 to move towards or away from each other along the horizontal groove, achieving flexible clamping and release of the battery. This provides secondary correction and positioning for the cylindrical battery. The protective pad protects the battery surface, preventing scratches and enhancing the stability and safety of the clamping.
