Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figs. 1 to 4As shown, this utility model discloses a battery repositioning device, comprising: a roller conveyor 1, a robotic arm 2 for transferring batteries on the roller conveyor 1, a positioning mechanism 3 for positioning batteries on the roller conveyor 1, and a repositioning mechanism 4 for gripping and changing the angle of the batteries; the roller conveyor 1 transports batteries through multiple rollers, and the positioning mechanism 3 is located between any two rollers, enabling the batteries to be transported to the position of the positioning mechanism 3.

[0023] Positioning mechanism 3 includes: a guide frame 31, which is fixedly installed on the roller conveyor 1. The guide frame 31 consists of a guide ramp and a limiting plate. The guide ramp guides the battery on the roller conveyor 1 to the center position, allowing the battery to pass through the space between the two limiting plates. This prevents the battery from shifting too much when aligned with the robotic arm 2, which would prevent the fixed robotic arm 2 from grabbing the battery through the repositioning mechanism 4. The limiting plate has a groove, the two sides of which are respectively aligned with the sides of the two rollers. A cylinder 34 is installed on the inner wall of the groove. The piston rod of the cylinder 34 is fixedly connected to a lifting block 33. The lifting block is provided with a ramp. The lower end of the ramp is lower than the top of the roller conveyor 1. The lifting block 33 is slidably installed in the groove. When the battery moves to the top of the ramp, the piston rod of the cylinder 34 pushes the lifting blocks 33 closer to each other, so that the ramp contacts the battery and pushes the battery upward, which facilitates the positioning mechanism 4 to grab the battery. A limit rod is fixedly connected to the lifting block 33. The limit rod slides and passes through the inner wall of the roller conveyor 1.

[0024] Furthermore, an mounting plate 32 is fixedly installed between the two guide racks 31. An infrared proximity switch is installed on the mounting plate 32. When the infrared proximity switch senses the battery, the positioning mechanism 3 is controlled by the control system to work.

[0025] The battery is conveyed by the roller conveyor 1. The battery contacts the guide plate and moves along the guide plate, so that the battery moves between the two limit plates. The position of the battery is detected by the infrared proximity switch. When the battery moves to be aligned with the lifting block 33, the cylinder 34 is activated. The piston rod of the cylinder 34 pushes the lifting blocks 33 closer to each other. The ramp on the lifting block 33 contacts the bottom edge of the battery and can push the battery upward so that the bottom of the battery is higher than the top of the roller conveyor 1, which is convenient for the positioning mechanism 4 to grasp.

[0026] The displacement mechanism 4 includes: a first motor 43, which is fixedly mounted on a gripping seat 41, which is mounted on the end of the robotic arm 2, and a fixed plate 42 is fixedly mounted on the gripping seat 41; the output shaft of the first motor 43 is fixedly connected to a bidirectional threaded rod 44, which is rotatably mounted on the gripping seat 41, and a movable plate 411 is threaded onto the bidirectional threaded rod 44. The lower end of the movable plate 411 is rotatably mounted on a sliding rod 48, which slides and passes through a second toothed wheel 412, which is rotatably mounted on the fixed plate 42. On plate 42, a limiting groove 481 is provided on the circumference of sliding rod 48, and a limiting block 4121 is installed on the inner circumference of second toothed wheel 412. The limiting block 4121 is slidably installed in the limiting groove 481. A synchronous belt 46 is installed on the second toothed wheel 412 and the first toothed wheel 410. The first toothed wheel 410 is fixedly installed on rotating shaft 47. Rotating shaft 47 is rotatably installed on fixed plate 42, and rotating shaft 47 is fixedly connected to the output shaft of second motor 45. Second motor 45 is fixedly installed on fixed plate 42. A clamping component is installed at one end of sliding rod 48.

[0027] The clamping components include: a clamping frame 49, a fixed clamping plate 493, a movable clamping plate 492, and a spring 491; the fixed clamping plate 493 is fixedly installed at both ends of the clamping frame 49, the movable clamping plate 492 is slidably installed on the clamping frame 49, and the two ends of the spring 491 are respectively connected to the fixed clamping plate 493 and the movable clamping plate 492.

[0028] Furthermore, the length of the movable clamp 492 is twice the length of the fixed clamp 493. During the descent of the gripping disc, the movable clamp 492 contacts the battery and is pushed by the battery, causing the movable clamp 492 to compress the spring 491 above it and stretch the spring 491 below it, thereby enabling the movable clamp 492 and the fixed clamp 493 to firmly clamp the battery.

[0029] During the battery gripping process, the robotic arm 2 adjusts the gripping seat 41 at its end to align with the battery in the vertical direction, then adjusts the gripping disc to descend, and the moving clamp 492 contacts the battery. The moving clamp 492 slides on the clamping frame 49, thereby compressing the upper spring 491 and stretching the lower spring 491. Then, the first motor 43 is started, and the output shaft of the first motor 43 drives the bidirectional threaded rod 44 to rotate. The two moving plates 411 approach each other, and the moving plates 411 drive the sliding rod 48 to move. The moving rod drives the clamping frame 49 to contact the battery. During the process of the gripping disc rising, the fixed clamp 493 contacts the bottom of the battery, so that the fixed clamp 493 and the moving clamp 492 clamp and fix the battery. The battery is clamped in multiple directions, which improves the firmness of the battery fixation.

[0030] During the battery transfer process by robotic arm 2, the second motor 45 is started. The output shaft of the second motor 45 drives the rotating shaft 47 to rotate, the rotating shaft 47 drives the first toothed wheel 410 to rotate, the first toothed wheel 410 drives the synchronous belt 46 to run, the synchronous belt 46 drives the second toothed wheel 412 to rotate, the second toothed wheel 412 drives the sliding rod 48 to rotate, and the sliding rod 48 drives the gripper 49 to rotate, thereby flipping the battery. Moreover, the end of robotic arm 2 can drive the gripper 41 to rotate, thereby adjusting the position of the battery to facilitate subsequent operations.

[0031] Working principle:

[0032] The square battery is moved towards the positioning mechanism 3 by the rollers on the roller conveyor 1, and the position of the battery is detected by an infrared proximity switch. When the battery contacts the guide ramp, it moves along the guide ramp towards the center line of the roller conveyor 1, allowing the battery to pass through the space between the two limit plates. When the battery moves above the lifting block 33, the cylinder 34 is activated, so that the ramp on the lifting block 33 can push the battery upward, suspending the battery in the air. The robotic arm 2 drives the gripper 41 to descend and align with the battery. The clamping frame 49 clamps the two sides of the battery, and the moving clamping plate 492 and the fixed clamping plate 493 clamp the upper and lower sides of the battery to fix the battery. During the process of the robotic arm 2 transferring the battery, the positioning mechanism 4 adjusts the orientation of the battery to facilitate subsequent operations. The structure of this device is simple, which can reduce costs and improve practicality.
