AI Technical Summary
During the test of battery packs for new energy vehicles, the uneven structural mass distribution of the battery pack causes the tail end to be heavier than the front end, which causes the positioning mechanism of the docking device to lift up the support plate of the battery pack, and the lifting amplitude of the front end of the support plate is higher than that of the rear end. The end is large, which tilts the connector plane of the battery pack, increasing the risk of loose joints and friction, and shortens the service life.
A fully automatic docking device is designed, including a detection mechanism and an adjustment mechanism. By detecting the inclination of the connector plane of the battery pack, the adjustment mechanism adjusts the inclination of the docking plate according to the detection data, so that the joints of the test equipment and the connectors of the battery pack are smoothly connected, avoiding uneven forces, reducing friction and reducing wear.
Through the cooperation of the detection and adjustment mechanism, ensure that the connector planes of the battery pack and the test equipment are parallel to each other, avoid uneven forces, reduce joint friction, extend service life, and improve testing efficiency and accuracy.

Description
Technical Field
[0001] The present invention relates to the technical field of battery pack testing, and in particular to a fully automatic docking device for testing a battery pack of a new energy vehicle. Background Art
[0002] New energy vehicle battery pack testing is an important part of ensuring battery pack performance, safety and reliability. The fully automatic docking device is an important equipment in the production and testing process of new energy vehicles. It can achieve fast, accurate and reliable connection between battery packs and test equipment, thereby improving test efficiency and accuracy.
[0003] When the fully automatic docking device is working, it first automatically identifies the interface position of the battery pack, and then uses a robotic arm or other automated mechanism to dock the connector of the test equipment with the connector of the battery pack. After docking, it establishes a connection between the battery pack and the test equipment to perform charge and discharge tests, etc.
[0004] The docking of the connectors of the battery pack and the test equipment requires extremely high precision to ensure the safety and stability of the connection. However, when connecting the battery pack to the test equipment, due to the uneven distribution of the structural mass of the transported battery pack, the tail end is heavier than the front end, and the positioning support mechanism of the docking device is distributed in the middle and rear parts, resulting in that when the positioning mechanism of the docking device lifts the support plate of the battery pack upward, the front end of the support plate is tilted more than the rear end, so that when the docking device docks the connector of the test equipment with the connector of the battery pack, the connector plane of the battery pack is in an inclined state, while the connector of the test equipment is in a horizontal state, and the gap between the two is uneven. The connection part is subjected to uneven force, which not only increases the risk of loosening of the connector, but also increases friction, aggravates the wear of the connectors on both sides, and shortens the service life.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] For example, see Figures 1 to 8 The present invention provides a technical solution: a fully automatic docking device for testing a battery pack of a new energy vehicle, comprising a docking device body 1; a docking platform 2, which is located at one end of the docking device body 1; a docking plate 3, which is connected to a connector of a testing device; a detection mechanism 4, which is located on both sides of the docking plate 3, and which detects the inclination of the connector plane of the battery pack during docking; an adjustment mechanism 5, which is located between the docking plate 3 and the docking platform 2, and after the detection mechanism 4 detects the inclination of the connector plane of the battery pack, the adjustment mechanism 5 adjusts the inclination of the docking plate 3 accordingly.
[0031] When the battery pack conveying platform transports the battery pack to the test position, the handling device in the workshop will first place the battery pack horizontally on the conveying platform. In order to facilitate the loading and unloading of the battery pack, the placement plane of the conveying platform is horizontal. When the battery pack conveying platform moves to the outside of the docking device body 1, the docking device body 1 supports the middle and rear part of the battery pack conveying platform. After the docking device body 1 is connected to the battery pack conveying platform, the docking platform 2 drives the docking plate 3 to move upward, so that the detection mechanism 4 is close to the battery pack conveying platform. The inclination amplitude of the front end of the battery pack conveying platform is detected by the set detection mechanism 4, so as to judge the inclination degree of the joint fixed inside the battery pack conveying platform. The adjustment mechanism 5 synchronously adjusts the inclination of the docking plate 3 according to the data detected by the detection mechanism 4, so that the test equipment joint plane inside the docking plate 3 and the battery pack joint plane are parallel to each other, so as to facilitate the smooth docking of the test equipment joint and the battery pack joint, avoid uneven force on the connection part, reduce the friction between the joints, reduce the wear of the joints, and improve the service life.
[0032] The docking platform 2 includes a base 20, which is located on the docking device body 1, a support plate 21 is provided above the base 20, a detection mechanism 4 is connected to the support plate 21, a cylinder 22 is installed between the base 20 and the support plate 21, a support plate 23 is provided above the support plate 21, a cylinder 24 is installed between the support plate 21 and the support plate 23, and the adjustment mechanism 5 is located between the support plate 23 and the docking plate 3.
[0033] When docking the connector of the test equipment with the connector of the battery pack, the connector of the test equipment is fixed on the docking plate 3, and the support plate 21 is driven to move upward by the cylinder 22, so that the detection mechanism 4 is close to the battery pack conveying platform, and the cylinder 22 controls the upward movement distance of the support plate 21 to be a preset fixed value. When the cylinder 22 completes its work, the detection mechanism 4 is used to detect the inclination amplitude of the front end of the battery pack conveying platform, so as to judge the inclination degree of the connector fixed inside the battery pack conveying platform, and the adjustment mechanism 5 synchronously adjusts the inclination of the docking plate 3 according to the data detected by the detection mechanism 4, so that the test equipment connector plane inside the docking plate 3 and the battery pack connector plane are parallel to each other, and the support plate 23 is driven to move by the cylinder 24, and the support plate 23 drives the inclined docking plate 3 close to the battery pack connector, so that the battery pack connector and the connector of the test equipment are docked smoothly, avoiding uneven force on the connection part.
[0034] The detection mechanism 4 includes support frames 40 respectively located on both sides of the first support plate 21. A detection rod 41 is slidably connected to the inner wall of the support frame 40. A reset spring 42 is fixedly connected to the bottom end of the detection rod 41, and the reset spring 42 is fixedly connected to the inner wall of the support frame 40. One end of the detection rod 41 close to the reset spring 42 is fixedly connected with a connecting rope 43. A guide wheel 44 is arranged outside the connecting rope 43, and the guide wheel 44 is fixedly connected to the inner wall of the support frame 40. The end of the connecting rope 43 far from the detection rod 41 is connected to the adjusting mechanism 5.
[0035] When the first air cylinder 22 drives the first support plate 21 to move upward, the first support plate 21 drives the two support frames 40 to move upward by a fixed distance. Since the detection rod 41 passes through the support frame 40, when the support frame 40 approaches the battery pack conveying platform, the detection rod 41 will first contact the front end of the battery pack conveying platform.
[0036] If the front end of the battery pack conveying platform is not inclined, let the distance that the detection rod 41 slides relative to the support frame 40 be X.
[0037] When the front end of the battery pack conveying platform is tilted upward, it can be deduced that the distance between the front end of the battery pack conveying platform and the support frame 40 increases. In this state, after the first air cylinder 22 pushes the first support plate 21 to move upward by a fixed stroke, let the distance that the detection rod 41 slides relative to the support frame 40 be L. Since the detection rod 41 does not contact the battery pack conveying platform before the first air cylinder 22 pushes the support plate to move, it can be deduced that: L < X, that is, when the front end of the battery pack conveying platform is tilted upward, the sliding distance of the detection rod 41 is less than the sliding distance of the detection rod 41 relative to the support frame 40 when the front end of the battery pack conveying platform is not inclined.
[0038] And from this, it can be deduced that the greater the upward tilt amplitude of the front end of the battery pack conveying platform, the smaller the sliding distance of the detection rod 41 relative to the support frame 40.
[0039] The detection rod 41 moves downward to compress the reset spring 42 and pulls the connecting rope 43. The connecting rope 43 drives the adjusting mechanism 5 to work. The adjusting mechanism 5 adjusts the inclination of the docking plate 3 according to the sliding distance of the detection rod 41, so that the joint plane of the test device is parallel to the joint plane of the battery pack.
[0040] The adjusting mechanism 5 includes a plurality of connecting seats 50 located below the docking plate 3, two connecting seats 50 are provided and respectively located on both sides of the docking plate 3, the two connecting seats 50 are symmetrically distributed on both sides of the docking plate 3, one connecting seat 50 is fixedly connected to the docking plate 3, and the other connecting seat 50 is slidably connected to the docking plate 3, a push rod 51 is rotatably connected to the outer side of the connecting seat 50, a fixed cylinder 52 is provided on the outer side of the push rod 51, the fixed cylinder 52 is fixedly connected to the support plate 23, a piston plate 1 53 is fixedly connected to one end of the top plate close to the fixed cylinder 52, and a driving member 54 is provided at the end of the fixed cylinder 52 away from the connecting seat 50 for pushing the push rod 51 to move upward according to the descending distance of the detection rod 41.
[0041] When the adjustment mechanism 5 is working, the two driving members 54 correspond to the detection rods 41 on both sides respectively. When the detection rod 41 slides down, the connecting rope 43 is pulled. The connecting rope 43 adjusts the driving force of the driving member 54. The driving member 54 drives the piston plate 53 on the inner wall of the fixed cylinder 52 to move upward. Since the detection rods 41 on both sides slide down at different distances, the driving member 54 drives the piston plate 53 to slide on the inner wall of the fixed cylinder 52 at different distances. The piston plate 53 drives the push rod 51 to move upward. While the push rod 51 slides relative to the connecting seat 50, it pushes the connecting seat 50 to move upward, and makes one connecting seat 50 slide relative to the inner wall of the docking plate 3, so that the test equipment connector plane inside the docking plate 3 and the battery pack connector plane are parallel to each other.
[0042] The driving member 54 includes a liquid storage cylinder 55 fixedly connected to the inner wall of the support frame 40, a piston plate 2 56 is slidably connected to the inner wall of the liquid storage cylinder 55, a cylinder 3 57 is fixedly connected to the top of the piston plate 2 56, and the cylinder 3 57 is fixedly connected to the inner wall of the support frame 40. The bottom of the liquid storage cylinder 55 is connected to an infusion tube 1 58, and an adjusting member 59 is provided at one end of the infusion tube 1 58 away from the liquid storage cylinder 55, and an infusion tube 2 510 is connected between the adjusting member 59 and the fixed cylinder 52.
[0043] After the cylinder 1 22 is stretched, the cylinder 3 57 pushes the piston plate 2 56 to move a fixed distance. The piston plate 2 56 moves to cooperate with the liquid at the bottom of the liquid storage cylinder 55 to be transported to the adjusting member 59 through the infusion tube 1 58. Since the connecting rope 43 is pulled when the detection rod 41 slides downward, the adjusting member 59 controls different liquid outputs according to the different sliding distances of the detection rod 41. The smaller the sliding distance of the detection rod 41, the more liquid is sent into the infusion tube 2 510 by the adjusting member 59, which makes the piston plate 1 53 move more upward on the inner wall of the fixed cylinder 52. The smaller the sliding distance of the detection rod 41, the greater the tilting amplitude of the front end of the battery pack conveying platform is, so as to cooperate with the docking plate 3 and the battery pack conveying platform to be parallel to each other.
[0044] The adjusting member 59 includes an adjusting cylinder 511 fixedly connected to the inner wall of the support frame 40. The inner diameter of the adjusting cylinder 511 is the same as the inner diameter of the fixed cylinder 52. The bottom of the adjusting cylinder 511 is respectively communicated with the first infusion tube 58 and the second infusion tube 510. A piston plate three 512 is slidably connected to the inner wall of the adjusting cylinder 511. A limiting member 513 for limiting the position of the piston plate three 512 is provided at the top of the piston plate three 512, and the limiting member 513 is connected to the connecting rope 43.
[0045] When the first cylinder 22 pushes the first support plate 21 to move upward, the limiting member 513 releases the restriction on the piston plate three 512. When the detection rod 41 slides downward, the detection rod 41 synchronously drives the piston plate three 512 to rise on the inner wall of the adjusting cylinder 511 through the connecting rope 43, and the sliding distance of the detection rod 41 is the same as the rising distance of the piston plate three 512 on the inner wall of the adjusting cylinder 511.
[0046] When the detection rod 41 does not tilt at the front end of the battery pack conveying platform, the sliding distance of the detection rod 41 is X. Then the sliding distance of the piston plate three 512 on the inner wall of the adjusting cylinder 511 is X. That is, the volume that can be accommodated at the bottom of the adjusting cylinder 511 is: V1 = π×r^2×X.
[0047] When the front end of the battery pack conveying platform is tilted, the sliding distance of the detection rod 41 is L. Then the sliding distance of the piston plate three 512 on the inner wall of the adjusting cylinder 511 is L. That is, the volume that can be accommodated at the bottom of the adjusting cylinder 511 is: V2 = π×r^2×L.
[0048] Since X > L, it can be known that V2 < V1. Let the volume of the liquid discharged from the liquid storage cylinder 55 after the third cylinder 57 extends a fixed stroke be the same as V1. Thus, when the conveying platform of the battery pack is not tilted, all the liquid discharged from the liquid storage cylinder 55 enters the adjusting cylinder 511 for storage. At this time, there is no liquid in the fixed cylinder 52 to push the piston plate one 53 to slide in the fixed cylinder 52, and the docking plate 3 remains horizontal.
[0049] When the conveying platform of the battery pack is tilted, since the inner diameter of the adjusting cylinder 511 is the same as the inner diameter of the fixed cylinder 52, the volume of the liquid discharged into the fixed cylinder 52 is V1 - V2 = π×r^2×(X - L). In the fixed cylinder 52, the upward moving distance of the piston plate one 53 is X - L, and X - L is the distance by which the conveying platform of the battery pack翘起 (I'm not sure what this word exactly means here, maybe it's "tilts up") is higher than the horizontal state. By jacking up different heights at both ends of the docking plate 3, it is coordinated to keep the joint plane of the test equipment parallel to the joint plane of the battery pack.
[0050] The limiting member 513 includes a connecting rod 514 fixedly connected to the top of the piston plate three 512. The top of the connecting rod 514 is fixedly connected to the connecting rope 43. An iron rod 515 is fixedly connected to the outside of the connecting rod 514. An electromagnet 516 is provided at the opening of the adjusting cylinder 511.
[0051] When the cylinder 22 pushes the support plate 21 to move upward, the electromagnet 516 is powered off, so that the iron rod 515 can slide on the surface of the electromagnet 516, and the detection rod 41 slides down and pulls the connecting rope 43. The connecting rope 43 pulls the connecting rod 514 to move upward, and the connecting rod 514 drives the iron rod 515 to slide upward on the surface of the electromagnet 516. When the cylinder 3 57 is extended, the electromagnet 516 is powered on. At this time, the electromagnet 516 fixes the iron rod 515 to prevent the liquid from entering the adjusting cylinder 511 and changing the position of the piston plate 3 512 in the adjusting cylinder 511.
[0052] Embodiment 2. In this embodiment 2, other structures remain unchanged. The difference from embodiment 1 is that an infrared distance sensor 1 6 is installed on the docking plate 3, and an infrared distance sensor 2 7 is installed below the detection rod 41. The infrared distance sensor 2 7 is used to measure the distance that the detection rod 41 slides down. A controller 8 is installed on the surface of the docking plate 3. The controller 8 is connected to the infrared distance sensor 1 6 and the infrared distance sensor 2 7. A cylinder 4 9 is fixedly connected to the outside of the base 20. The cylinder 4 9 is installed on the surface of the docking device body 1. The controller 8 is connected to the cylinder 2 24 and the cylinder 4 9 respectively.
[0053] Taking into account that when the front end of the battery pack transport platform is tilted upward, the position of its rotation axis is uncertain, so that when the front end of the battery pack transport platform is tilted upward, the position of the joint in the vertical direction changes, and the rotation of the docking plate 3 is based on the position axis of the connecting seat 50 on one side. It can be seen that after the docking plate 3 is rotated, the test equipment joint on the surface of the docking plate 3 and the battery joint of the battery pack transport platform will not correspond. In order to avoid the adjusted surface joint of the docking plate 3 being unable to dock with the battery joint of the battery pack transport platform, before the cylinder 24 pushes the support plate 23 to move upward, the cylinder 4 9 works to drive the base 20 to slide on the surface of the docking device body 1, and the base 20 moves, so that the infrared distance sensor 1 6 moves. Since the docking plate 3 is parallel to the front end of the battery pack transport platform at this time, The infrared distance sensor 6 moves to cooperate with the detection of the distance between the infrared distance sensor 6 and the battery pack transport platform. Since the distance between the infrared distance sensor 6 and the test equipment joint on the surface of the docking plate 3 is fixed, the joint of the test equipment on the docking plate 3 is convex, and the joint of the battery pack transport platform is concave. Therefore, when the infrared distance sensor 6 detects that the distance with the battery pack transport platform increases, the surface infrared distance sensor 6 moves to the joint joint on the surface of the battery pack transport platform. The infrared distance sensor 6 transmits the distance information to the controller 8, and the controller 8 processes the signal and sends a signal to the cylinder 9 when the distance detected by the infrared distance sensor 6 increases. The cylinder 9 drives the base 20 to move in the return direction, and the moving distance is as follows:
[0054] As shown in the attached figure of the instruction manual Figure 8As shown, since the inclination of the docking plate 3 is rotated with the connecting seat 50 on one side as the axis, and the distance between the two top rods 51 is set to M, the size of M is known and unchanged, the height difference between the two ends of the docking plate 3 is set to N, and N is the distance difference measured by the two infrared distance sensors 7, assuming that the inclination angle of the docking plate 3 is a, then tan a=N / M, so the inclination angle a of the docking plate 3 can be calculated.
[0055] The distance between the infrared distance sensor 6 and the test equipment docking joint on the surface of the docking plate 3 is set to K. Since the distance between the infrared distance sensor 6 and the test equipment docking joint on the surface of the docking plate 3 is fixed, K is a known quantity.
[0056] Assuming that the distance moved by the infrared distance sensor 6 in the horizontal direction is T, then T=K cosa, so the return distance of the cylinder 9 can be calculated to ensure that the connector of the test equipment and the connector of the battery pack can be stably connected at different inclination angles of the front part of the battery pack transportation platform.
