Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and in particular to a lithium battery collecting robot and a turning mechanism. Background Art

[0002] Lithium-ion battery is a secondary battery rechargeable battery. It mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes. When charging, Li+ is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state. The opposite is true when discharging. Lithium batteries have high energy density, high average output voltage, low self-discharge, no memory effect, a wide operating temperature range of -20℃~60℃, excellent cycle performance, fast charge and discharge, charging efficiency up to 100%, high output power, long service life, and do not contain toxic and harmful substances. They are called green batteries.

[0003] During the production and manufacturing process of lithium batteries, the batteries need to be distributed and collected. In the prior art, the battery transmission process is usually carried out by conveyor belts, and the batteries are collected when they are transmitted to the end of the conveyor belt. During the collection, it is necessary to ensure that the posture of each transmitted battery remains stable, so as to facilitate the subsequent rapid and automatic distribution and loading. However, when the battery is running on the conveyor belt, a certain posture deviation sometimes occurs. In particular, when it comes to square lithium batteries, due to their small size, they can also be transported normally on the conveyor belt when the electrode end is facing down. When transferred to the conveyor belt, they are easily reversed, and the electrodes of square lithium batteries may also be reversed. Therefore, it is necessary to specially identify the direction of the electrodes to prevent the subsequent battery distribution and collection from being reversed, causing adverse consequences. There is also a device in the prior art that discharges batteries with unqualified postures from the conveyor belt, but this device can only discharge batteries, and new batteries with correct postures cannot be added at the conveyor belt discharge position, which reduces the utilization rate of the conveyor belt, and causes subsequent equipment to detect whether there is a battery at this position, so the transmission and distribution efficiency is low. The prior art lacks equipment for correcting the posture of square lithium batteries during transmission.

[0004] Therefore, it is necessary to provide a lithium battery collection robot to solve the above technical problems. Summary of the invention

[0052] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] A lithium battery collection robot comprises a frame 1, a main conveyor belt 2, a detection component 3 and a control cabinet installed on the frame 1;

[0054] The main conveyor belt 2 is horizontally arranged on the frame 1 and is used to convey the square lithium batteries 7 to be distributed;

[0055] The detection component 3 is located above the main conveyor belt 2. The detection component 3 is installed on the frame 1. The detection component 3 is used to detect whether the posture of the square lithium battery 7 on the main conveyor belt 2 is correct.

[0056] It also includes a first flip assembly 4 and a second flip assembly 5 which are sequentially arranged along the transmission direction of the main conveyor belt 2, and an auxiliary conveyor belt 6 which is installed beside the main conveyor belt 2;

[0057] The first flip assembly 4 is used to flip the square lithium battery 7 in an incorrect posture on the main conveyor belt 2 along the horizontal axis;

[0058] The second flipping assembly 5 is used to flip the square lithium battery 7 in an incorrect posture on the main conveyor belt 2 along the vertical axis;

[0059] The transmission direction of the auxiliary conveyor belt 6 is consistent with the transmission direction of the main conveyor belt 2, and the first turnover assembly 4 is arranged on the auxiliary conveyor belt 6;

[0060] The detection assembly 3, the first flip assembly 4, the second flip assembly 5 and the auxiliary conveyor belt 6 are all electrically connected to the control cabinet.

[0061] The correct posture mentioned above is that the electrode end of the square lithium battery 7 is set upward, and the positive electrode of the square lithium battery 7 is close to the right side of the main conveyor belt 2 along the transmission direction, and the square lithium battery 7 is in a vertical state as a whole. The rest of the postures are abnormal postures. For example, the negative electrode of the square lithium battery 7 is close to the right side of the main conveyor belt 2 along the transmission direction. In this case, the square lithium battery 7 needs to be flipped by the second flipping component 5. For another example, the electrode end of the square lithium battery 7 is located at the bottom. In this case, the square lithium battery 7 needs to be flipped by the first flipping component 4.

[0062] When detecting the square lithium battery 7, the detection component 3 mainly detects the position and state of the square lithium battery 7 on the main conveyor belt 2, determines whether the electrodes of the square lithium battery 7 are located at the top and whether the position of the electrodes of the square lithium battery 7 is correct. In addition, it can also detect whether the square lithium battery 7 is in a vertical state on the main conveyor belt 2, so as to determine whether the posture of the square lithium battery 7 needs to be corrected.

[0063] The detection assembly 3 includes a first detection mechanism 3a, a second detection mechanism 3b and a third detection mechanism 3c which are sequentially arranged along the transmission direction of the main conveyor belt 2. The first detection mechanism 3a is located on the side of the first flip assembly 4 close to the starting end of the main conveyor belt 2, the second detection mechanism 3b is located on the side of the second flip assembly 5 close to the starting end of the main conveyor belt 2, and the third detection mechanism 3c is located on the side of the second flip assembly 5 close to the end of the main conveyor belt 2. The first detection mechanism 3a is used to detect whether the electrode of the square lithium battery 7 is located at the top, the second detection mechanism 3b is used to detect whether the electrode position of the square lithium battery 7 is correct, and the third detection mechanism 3c is used to detect whether the plane where the square lithium battery 7 is located is perpendicular to the transmission direction when the material is about to be discharged at the end of the main conveyor belt 2. Preferably, the detection mechanism can use a camera to obtain pictures by taking pictures, and judge the posture of the battery by the pictures.

[0064] During operation, the square lithium batteries 7 are transported in sequence along the transmission direction on the main conveyor belt 2, and the first flip assembly 4 and the second flip assembly 5 correct the square lithium batteries 7 on the main conveyor belt 2 that are in an abnormal posture. During the correction process, the main conveyor belt 2 does not need to stop and wait, and can put the corrected square lithium batteries 7 back to their initial transmission positions on the main conveyor belt 2, and fill the vacant positions on the main conveyor belt 2 during the correction operation, which greatly improves the transmission efficiency of the main conveyor belt 2, reduces the difficulty of subsequent placement, and facilitates correct unloading operations. The first flipping assembly 4 is used to push the upside-down square lithium battery 7 in the main conveyor belt 2 out of the main conveyor belt 2 and flip it on the side of the main conveyor belt 2, and introduce the flipped square lithium battery 7 into the main conveyor belt 2 according to the original transmission order; the second flipping assembly 5 is arranged on the frame 1, and the second flipping assembly 5 is located on the side of the first flipping assembly 4 close to the end of the main conveyor belt 2. The second flipping assembly 5 is used to drive the square lithium battery 7 with reversed electrode direction, so that the square lithium battery 7 is turned over during the transmission process on the main conveyor belt 2, and the inverted square lithium battery 7 is straightened.

[0065] Since the square lithium battery 7 rotates directly on the surface of the main conveyor belt 2 when the second flipping component 5 is operated, if the electrode end is facing downward, the square lithium battery 7 is not stable enough and is easy to fall over, and the electrode is worn. Therefore, the operating sequence of first driving the first flipping component 4 to flip and then the second flipping component 5 to flip is adopted, which is convenient for accurately implementing the flipping function of the second flipping component 5, and at the same time can ensure that the square lithium batteries 7 enter the second flipping component 5 in sequence, reducing waiting time.

[0066] The auxiliary conveyor belt 6 can ensure that the square lithium battery 7 turned over by the first flipping component 4 can follow the transmission speed of the main conveyor belt 2, and reintroduce the turned square lithium battery 7 into the main conveyor belt 2 to restore its initial transmission order, thereby improving the transmission efficiency of the main conveyor belt 2 and keeping the main conveyor belt 2 running without stopping.

[0067] The first turning assembly 4 includes an ejection mechanism 4a, a turning mechanism 4b and a return mechanism 4c;

[0068] The ejection mechanism 4a is installed on the frame 1, and the ejection mechanism 4a is used to transfer the square lithium battery 7 in an incorrect posture on the main conveyor belt 2 to the turning mechanism 4b;

[0069] The flipping mechanism 4b is installed on the frame 1 and close to the starting end of the auxiliary conveyor belt 6, and is used to flip the square lithium battery 7 located on the flipping mechanism 4b along the horizontal axis;

[0070] The top return mechanism 4c is installed on the frame 1 and is located at the end of the auxiliary conveyor belt 6 , and is used to transfer the square lithium batteries 7 located on the auxiliary conveyor belt 6 to the main conveyor belt 2 .

[0071] When the first flipping assembly 4 is working, the ejection mechanism 4a outputs to eject the square lithium battery 7 with the electrode at the bottom on the main conveyor belt 2 out of the main conveyor belt 2, and the square lithium battery 7 is introduced into the first flipping assembly 4, and the square lithium battery 7 is flipped by the flipping mechanism 4b output so that its electrode end is directly above, and the correctly positioned square lithium battery 7 is transmitted forward through the auxiliary conveyor belt 6, and the square lithium battery 7 is driven by the auxiliary conveyor belt 6 to move quickly to the end, and then the square lithium battery 7 at the end of the auxiliary conveyor belt 6 is transported to the main conveyor belt 2 through the return mechanism 4c.

[0072] The flip mechanism 4b includes a mounting frame 4b4 disposed on the frame 1 and located on one side of the main conveyor belt 2 in the width direction, a rotating plate 4b3 rotatably disposed on the mounting frame 4b4, a flip frame 4b1 rotatably disposed on the mounting frame 4b4, and a push block 4b6. When the rotating plate 4b3 is observed in the direction of the rotation axis, the rotating plate 4b3 is L-shaped, and the rotation axis of the rotating plate 4b3 is disposed at the corner of the L. The flip frame 4b1 is U-shaped, and the rotation axis of the flip frame 4b1 is parallel to the rotation axis of the rotating plate 4b3. The rotation axis of the flip frame 4b1 is disposed in the middle part of the U-shape. In the direction of the rotation axis of the rotating plate 4b3, the two sides of the rotating plate 4b3 are located within the two sides of the U-shape of the flip frame 4b1, and the size of the two sides of the rotating plate 4b3 is smaller than the square lithium battery 7. A torsion spring 4b8 is arranged on the rotating shaft of the rotating plate 4b3, and the torsion spring 4b8 always has a tendency to rotate the rotating plate 4b3 toward the first state. In the first state, a part of the rotating plate 4b3 is vertical, and the other part is horizontal, and the horizontal part is located on the opposite side of the rotating axis of the flip frame 4b1 relative to the axis of the rotating plate 4b3, and the push block 4b6 is located on the opposite side of the rotating axis of the flip frame 4b1 relative to the axis of the rotating plate 4b3, and the push block 4b6 can move back and forth along the transmission direction to push against the rotating plate 4b3. When the square lithium battery 7 needs to be flipped using the first flip assembly 4, the square lithium battery 7 to be flipped is first pushed to the horizontal part of the rotating plate 4b3 located in the first state by the ejection mechanism 4a, and the push block 4b6 extends to push the rotating plate 4b3 to rotate in the direction of the flip frame 4b1. The torsion force of the torsion spring 4b8 is configured such that when the rotating plate 4b3 is in the first state, the torsion force of the torsion spring 4b8 is insufficient to support the gravity of the square lithium battery 7, and then when the rotating plate 4b3 rotates to a certain angle, the rotating plate 4b3 continues to rotate under the gravity of the square lithium battery 7. Preferably, the torsion force of the torsion spring 4b8 is further configured such that when the square lithium battery 7 changes from a vertical state to a horizontal state, the torsion force of the torsion spring 4b8 can just support the gravity of the square lithium battery 7. When the square lithium battery 7 changes to a horizontal state, the flip frame 4b1 starts to rotate, and the flip frame 4b1 abuts against the two side edges of the square lithium battery 7. When the flip frame 4b1 is rotated to a vertical state, the square lithium battery 7 is rotated 180° in total, realizing the upside-down flipping of the square lithium battery 7. When the flip frame 4b1 rotates to a vertical state, the square lithium battery 7 is just placed on the auxiliary conveyor belt 6, and the auxiliary conveyor belt 6 works to transport the square lithium battery 7 along the transmission direction. When moving to the end of the auxiliary conveyor belt 6 , the top-returning mechanism 4 c pushes the flipped square lithium battery 7 back onto the main conveyor belt 2 .The torsion spring 4b8 can effectively slow down the falling speed of the square lithium battery 7 and play a buffering role. After the square lithium battery 7 is taken away by the flip frame 4b1, the rotating plate 4b3 is automatically reset under the action of the torsion spring 4b8.

[0073] The flip frame 4b1 is driven by a flip motor 4b2, and the push block 4b6 is driven by a first cylinder 4b7.

[0074] The second flip assembly 5 includes a first flip mechanism 5a and a second flip mechanism 5b;

[0075] The first flipping mechanism 5a and the second flipping mechanism 5b are sequentially arranged on the main conveyor belt 2 along the transmission direction of the main conveyor belt 2;

[0076] The first turning mechanism 5a is used to turn over the square lithium battery 7 in an incorrect posture on the main conveyor belt 2 until the square lithium battery 7 moves to a point where its length direction is consistent with the transmission direction of the main conveyor belt 2;

[0077] The second flipping mechanism 5b is used to turn the square lithium battery 7 turned by the first flipping mechanism 5a back to the correct posture.

[0078] The first flipping mechanism 5a includes a second cylinder 5a1, a third cylinder 5a2, a first flipping guide plate 5a3 and a second flipping guide plate 5a4;

[0079] The second cylinder 5a1 is horizontally fixedly installed on the frame 1, and the output direction of the second cylinder 5a1 is perpendicular to the transmission direction of the main conveyor belt 2;

[0080] The first flip guide plate 5a3 and the second flip guide plate 5a4 are both vertically arranged, and the first flip guide plate 5a3 and the second flip guide plate 5a4 can move back and forth along a direction perpendicular to the transmission direction, and the first flip guide plate 5a3 and the second flip guide plate 5a4 are respectively located on both sides of the main conveyor belt 2;

[0081] The output end of the second cylinder 5a1 is fixedly connected to the first flipping guide plate 5a3, and the output end of the third cylinder 5a2 is fixedly connected to the second flipping guide plate 5a4;

[0082] The vertical plane where the first flip guide plate 5a3 and the second flip guide plate 5a4 are located is parallel to the transmission direction of the main conveyor belt 2. The first flip guide plate 5a3 is provided with an arc-shaped deflection guide section on one side close to the starting end of the main conveyor belt 2. When viewed from above, the arc-shaped deflection guide section gradually bends toward the outer side of the main conveyor belt 2 along the width direction in a direction away from the first flip guide plate 5a3.

[0083] There are two groups of second turning mechanisms 5b, which are respectively arranged on both sides of the main conveyor belt 2 in the width direction. Each second turning mechanism 5b includes a fourth cylinder 5b1 and an alignment push plate 5b2. The two alignment push plates 5b2 are respectively arranged at diagonal positions corresponding to the square lithium battery 7. When the two alignment push plates 5b2 are extended at the same time, the square lithium battery 7 can be rotated more than 45° around the vertical axis.

[0084] The fourth cylinder 5b1 is horizontally fixedly installed on the frame 1, and the output direction of the fourth cylinder 5b1 is horizontally arranged along a transmission direction perpendicular to the main conveyor belt 2.

[0085] The square lithium battery 7 can be turned over along the vertical axis and the direction of the electrode can be corrected through the first turning mechanism 5a and the second turning mechanism 5b, and the main conveyor belt 2 does not need to be stopped when the first turning mechanism 5a and the second turning mechanism 5b are working. That is, when the main conveyor belt 2 is in operation, the square lithium battery 7 on the main conveyor belt 2 is driven by the first turning mechanism 5a and the second turning mechanism 5b to realize the flipping function, thereby improving the transmission efficiency.

[0086] The square lithium battery 7 moves along the transmission direction on the main conveyor belt 2. During the movement, the arc-shaped deflection guide end of the first flipping guide plate 5a3 contacts, so that the speed of the square lithium battery 7 approaching the second flipping guide plate 5a4 is greater than the speed of the end contacting the first flipping guide plate 5a3, so that the square lithium battery 7 is deflected on the main conveyor belt 2. After deflecting to a certain angle, the first flipping guide plate 5a3 and the second flipping guide plate 5a4 are driven to approach each other by the output of the second cylinder 5a1 and the third cylinder 5a2, and the square lithium battery 7 is deflected ninety degrees by the clamping of the two. The square lithium battery 7 moves to the second flipping mechanism 5b under the drive of the main conveyor belt 2, and the output of the fourth cylinder 5b1 drives the straightening push plate 5b2 to be pushed forward, so that the square lithium battery 7 continues to deflect until it becomes a state in which the length direction is perpendicular to the transmission direction of the main conveyor belt 2 again. At this time, the square lithium battery 7 is rotated 180 degrees around the vertical axis as a whole, and the flipping process is completed.

[0087] A first limiting plate 2a is provided on both sides of the main conveyor belt 2. The first limiting plate 2a is provided with a first avoidance gap 2b for facilitating the operation of the first turnover assembly 4. The first limiting plate 2a is also provided with a second avoidance gap 2c for facilitating the operation of the second turnover assembly 5.

[0088] The robot further comprises a correction component 8 , which is provided with two groups. The two groups of correction components 8 are respectively installed at two ends of the second flip component 5 along the transmission direction of the main conveyor belt 2 .

[0089] Each group of correction components 8 includes a stop plate 8a and a fifth cylinder 8b; two stop plates 8a are provided, and the two stop plates 8a are respectively installed on both sides of the width direction of the main conveyor belt 2, and each stop plate 8a includes a limit plate 8a1 and a blocking plate 8a2, the vertical plane where the limit plate 8a1 is located is parallel to the transmission direction, the two blocking plates 8a2 are located between the two limit plates 8a1 and are aligned with each other in the horizontal direction perpendicular to the transmission direction, the plane where the two blocking plates 8a2 are located is perpendicular to the transmission direction, and the two stop plates 8a can be close to or away from each other under the drive of the fifth cylinder 8b;

[0090] There are two fifth cylinders 8b, which are respectively installed on both sides of the main conveyor belt 2 along the width direction. The output end of the fifth cylinder 8b is fixedly connected to the stop plate 8a, and the output direction of the fifth cylinder 8b is perpendicular to the transmission direction of the main conveyor belt 2.

[0091] When the correction component 8 is working, the square lithium battery 7 that is about to enter the second flip component 5 and the square lithium battery 7 at the end of the main conveyor belt 2 can be corrected so that the arrangement direction of the positive and negative electrodes of the square lithium battery 7 is perpendicular to the transmission direction. Specifically, as the square lithium battery 7 moves forward, it is stopped by the stop plates 8a located on both sides of the main conveyor belt 2, so that the square lithium battery 7 gradually rotates until the arrangement direction of the positive and negative electrodes is perpendicular to the transmission direction. At this time, the output end of the fifth cylinder 8b drives the stop plate 8a to retract, so that the square lithium battery 7 can continue to be transported backward through the correction component 8, completing the correction function of the square lithium battery 7.
