In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0057] Please refer to Figures 1 to 6 The preferred embodiment provides a tray for automatic assembly of power batteries, and the tray tooling mainly includes a tray body 10, a support block 20 and an adjustment mechanism 30.

[0058] The tray body 10 is a supporting structure, which is mainly used as a supporting platform. In this preferred embodiment, the tray body 10 is a square flat plate structure.

[0059] There are multiple support blocks 20, which are relatively evenly fixed on the tray body 10 to support the power battery. The support blocks 20 of the utility model only realize the supporting function. When implemented, the power battery is placed on the support blocks 20 to support the power battery. In the preferred embodiment of the present invention, the support blocks 20 are square-shaped structures, supported by support rods, and the top surface heights of multiple support blocks 20 are consistent.

[0060] The adjustment mechanism 30 is disposed on the tray body 10 , and the adjustment mechanism 30 can be adjusted to achieve a change in the position of the positioning pins 35 disposed thereon so as to adapt to the positioning of power batteries of different specifications.

[0061] The power battery assembly positioning of the utility model adopts the form of matching the positioning pin and the positioning hole. The positioning holes of power batteries of different specifications (volume, capacity, vehicle type, etc.) are located in different positions. Therefore, when assembling, it is necessary to adjust the positioning pin of the tray tooling to correspond to the positioning hole of the power battery to achieve accurate positioning, so as to facilitate assembly, such as tightening the bolts.

[0062] In a preferred embodiment, the adjustment mechanism 30 includes a gear 31 , a linear rail 32 , a linear rail slider 33 , a rack 34 , a limiter and a positioning pin 35 .

[0063] The gear 31 is rotatably arranged on the tray body 10. There are two linear rails 32, which are fixedly arranged on the tray body 10 and on both sides of the gear 31, and the two linear rails 32 extend along the left and right sides of the tray body 10. There are two linear rail sliders 33, which are respectively arranged on the two linear rails 32 in a one-to-one correspondence so as to be able to slide on the linear rails 32 to the left and right sides of the tray body 10. There are two racks 34, which are respectively arranged on the two linear rail sliders 33 in a one-to-one correspondence, and the racks 34 are meshed with the gear 31. The limiter is arranged on the tray body 10 and can act on one of the linear rail sliders 33 to limit the linear rail slider 33 from sliding. There are two positioning pins 35, which are respectively arranged on the two linear rail sliders 33 in a one-to-one correspondence.

[0064] During implementation, the positions of the two locating pins 35 are adjusted according to the specifications of the power battery to be placed. During adjustment, one of the linear rail sliders 33 is moved, and the rack 34 on it moves together, driving the gear 31 to rotate. When the gear 31 rotates, it can drive the other rack 34 to move in the opposite direction, and the linear rail slider 33 connected thereto moves together, that is, the two linear rail sliders 33 are moved in opposite directions. The two locating pins 35 are located on the two linear rail sliders 33, and they also move in opposite directions at this time, that is, the two locating pins 35 can move closer to or away from each other. The positions of the two locating pins 35 are adjusted by moving the two locating pins 35 closer to or away from each other. After adjusting to a certain position, the limiter is operated to limit the linear rail slider 33 from sliding, and the positions of the two locating pins 35 are fixed at this time. After the two positioning pins 35 are fixed, the power battery is placed on the support block 20. When placed, the positioning hole of the power battery is opposite to the positioning pin 35, and the positioning pin 35 can be inserted into the positioning hole. At this time, the support block 20 can support the power battery, and the two positioning pins 35 can position the power battery. According to the specifications of the power battery to be adapted, the position of the positioning pin 35 can be adjusted by adjusting a linear rail slider 33 to achieve positioning. This method is fast and simple to operate, supports platform positioning strategies for power batteries of multiple specifications, has good compatibility, and is very suitable for flexible production lines.

[0065] In a preferred embodiment, the limiting member includes a fixed platform 36, a limiting pin shifting slot 37 and a limiting pin 38. The fixed platform 36 is fixedly arranged on the tray body 10, and a through hole facing the linear rail slider 33 is opened on the fixed platform 36. The limiting pin shifting slot 37 is opened on the linear rail slider 33 that cooperates with the limiting member. There are multiple limiting pin shifting slots 37, and the positions and spacings are adapted and set according to the positioning holes of the battery specifications, and are arranged along the sliding direction of the linear rail slider 33. The limiting pin 38 passes through the through hole on the fixed platform 36 and can move close to or away from the linear rail slider 33 in the through hole, so that when the end of the limiting pin 38 is close to the linear rail slider 33, it can be located in one of the limiting pin shifting slots 37. During implementation, the linear rail slider 33 is moved so that one of the stop pin shift slots 37 is aligned with the end of the stop pin 38. At this time, the stop pin 38 is moved to insert the end of the stop pin 38 into the opposite stop pin shift slot 37. The linear rail slider 33 cannot move any further, and the positions of the two positioning pins 35 are fixed. When adjusting again, the stop pin 38 is pulled out, and the linear rail slider 33 is moved so that the other stop pin shift slot 37 is aligned with the end of the stop pin 38. At this time, the stop pin 38 is moved to insert the end of the stop pin 38 into the opposite stop pin shift slot 37. The linear rail slider 33 cannot move any further, and the positions of the two positioning pins 35 are fixed. By inserting the limit pin 38 into different limit pin gear slots 37, the position adjustment and fixation of the two locating pins 35 can be achieved. The position adjustment and fixation method is very simple and efficient, and the position fixation of the two locating pins 35 is accurate. Through the precise positioning of the locating pins 35, the positioning accuracy of the power battery can be improved, the occurrence of bolt blocking hole rate can be reduced, and the on-site rework time can be reduced.

[0066] In this preferred embodiment, two positioning pins 35 are relatively arranged at the ends of the two linear rail sliders 33 that are away from each other and close to the left and right edges of the tray body 10 to achieve left and right positioning. The top of the positioning pin 35 is conical to facilitate insertion into the positioning hole of the power battery.

[0067] In this preferred embodiment, a baffle 39 is provided above the gear 31, and the baffle 39 covers the gear 31 and the linear rail sliders 33, racks 34, etc. on both sides thereof, so as to prevent debris from falling onto the gear 31 and racks 34 below during the assembly process and affecting the operation of the device.

[0068] The second positioning pins 40 are respectively provided at the front and rear ends of the tray body 10, and the bottom of the second positioning pin 40 is rotatably connected to the tray body 10 so that the second positioning pin 40 can be switched between the horizontal and vertical states. The second positioning pin 40 is used as a supplementary positioning to achieve positioning at the front and rear ends. When the front and rear ends are required to be positioned, the second positioning pins 40 at both ends are erected to be in a vertical state and can be inserted into the positioning holes of the power battery. When the front and rear ends are not required to be positioned, the second positioning pins 40 at both ends are lowered to be in a horizontal state. The second positioning pins 40 in the horizontal state will not affect the positioning of the positioning pins 35.

[0069] The plurality of support blocks 20 are arranged in two rows, respectively located on the left and right sides of the tray body 10, so as to stably support the power battery. In this exemplary embodiment, there are six support blocks 20, three in each row, and the front, middle and rear can all support the power battery.

[0070] The tray body 10 is provided with a tightening rod 50, which can cooperate with an external driving mechanism to achieve automatic assembly. There are multiple tightening rods 50, and different tightening rods 50 can be adapted to the assembly of power batteries of different specifications.

[0071] The tightening connecting rod 50 includes a floating support body 51, a sleeve 52, a tightening rod 53, a tightening sleeve 54, a tightening head 55 and an elastic body 56. The floating support body 51 is arranged on the tray body 10, and has a through hole that passes through from top to bottom. The sleeve 52 is sleeved in the floating support body 51 through the sleeve locking member 57 and cannot move downward relative to the floating support body 51. Specifically, the top of the sleeve 52 is provided with an outward flange 521, and the size of the flange 521 is larger than the through hole to ensure that the sleeve 52 cannot move downward. The tightening rod 53 is sleeved in the sleeve 52, and the tightening rod 53 matches the sleeve 52. The outer diameter of the tightening rod 53 is equal to the inner diameter of the sleeve 52. The tightening rod 53 can rotate and move up and down in the sleeve 52 without swinging. The tightening sleeve 54 is arranged on the top of the tightening rod 53, and is provided with an inner hexagon or outer hexagon end for connecting with the bolt head. The tightening head 55 is arranged at the bottom of the tightening rod 53, and is used to connect with the external driving mechanism to transmit the driving force. One end of the elastic body 56 abuts against the shaft sleeve 52, and the other end abuts against the tightening sleeve 54. The elastic body 56 has elasticity, so that when the shaft sleeve 52 is compressed, the elastic body 56 can be pressed downward, and can be restored after the pressure is released. The elastic body 56 preferably uses a compression spring.

[0072] During implementation, the power battery is placed on the support block 20 and positioned by the positioning pin 35. At this time, the tightening sleeve 54 of the tightening rod 50 aligned with the bolt of the power battery abuts and cooperates with the bolt head. For example, the tightening sleeve 54 with an inner hexagonal structure is inserted into the bolt head. The abutment will cause the tightening rod 53 of the tightening rod 50 aligned with the bolt of the power battery to compress the elastic body 56 to drive the tightening sleeve 54, the tightening head 55, etc. downward and have an upward trend. The power is transmitted to the tightening head 55 through an external driving mechanism (such as a tightening gun, etc.), driving the tightening head 55 to rotate. At this time, the tightening rod 53 rotates and turns to rotate in the direction of tightening the bolt, at this time driving the tightening sleeve 54 to rotate, and the tightening sleeve 54 rotates and drives the bolt to rotate. The bolt is tightened and upward, and under the action of the elastic body 56, the tightening rod 53 is also upward with the tightening until the bolt is tightened. Other tightening rods 50 that are not aligned with the bolt of the power battery will be pressed down by the power battery, but will not affect the assembly of the power battery. Multiple sets of tightening connecting rods 50 can be adapted to the assembly of power batteries of different specifications. The utility model can cooperate to realize the automatic tightening of bolts by setting the tightening connecting rods 50, facilitate the self-aligning screw holes, automatic tightening, and support the automation process.

[0073] The upper portion of the shaft sleeve 52 is provided with a convex edge 521 , and the lower portion passes through the floating support body 51 and is provided with a shaft sleeve locking member 57 to limit the shaft sleeve 52 from moving up and down on the floating support body 51 .

[0074] Furthermore, there is a gap between the bushing 52 and the floating support body 51, and the gap is preferably 1-3 mm. The upper and lower parts of the bushing 52 are provided with lateral floating components, so that lateral floating, such as horizontal floating, can be achieved by setting the lateral floating components, so that the tightening sleeve 54 on the tightening connecting rod 50 can be fine-tuned to meet the relative position tolerance between the vehicle body positioning hole and the vehicle body power battery welding screw hole (such as + / -1.5 mm), realize automatic hole alignment, and ensure that the tightening sleeve 54 at the end of the tightening rod 53 can accurately enter the screw hole.

[0075] The transverse floating assembly includes a first abutment 58, a second abutment 59, an annular stopper 510 and a circular rolling body 511. The first abutment 58 is fixedly sleeved on the shaft sleeve 52; the second abutment 59 is installed on the floating support body 51; the annular stopper 510 is movably sleeved on the shaft sleeve 52, and the annular stopper 510 is located between the first abutment 58 and the second abutment 59, and the annular stopper 510 is provided with a plurality of stopper holes along the circumferential direction; the circular rolling body 511 is placed in the stopper holes of the annular stopper 510 and can roll, and the circular rolling body 511 abuts against the first abutment 58 and the second abutment 59 respectively. When the tightening rod 53 is not aligned with the screw hole, it is necessary to move the tightening rod 53 so that the tightening sleeve 54 is aligned and enters the screw hole. By fine-tuning the tightening rod 53 laterally, the circular rolling body 511 rolls, and at the same time, the drive sleeve 52 moves, the tightening rod 53 is fine-tuned, and the tightening sleeve 54 is aligned and enters the screw hole, thereby realizing automatic hole finding and alignment.

[0076] The utility model provides a tray for automatic assembly of power batteries, which adopts a new power battery compatibility assembly process and is very suitable for flexible production lines, which is simple and convenient. The gear rack design can adjust the distance between the locating pin and the center gear in both directions, thereby changing the relative distance between the two locating pins to achieve compatibility with power batteries of different widths. The utility model has a high degree of integration, and can switch the power battery locating pins of different vehicle models with one key, which saves time for on-site production, and integrates a tightening rod for convenient tool operation. The positioning accuracy of the power battery is improved, the occurrence of bolt blocking hole rate is reduced, and the on-site rework time is reduced. The new function of automatic tightening rod is added, which is convenient for use with a robot or a servo tightening shaft to realize the automatic positioning and tightening process of the power battery, reduce the number of on-site operators, and improve the automation rate of general assembly.

[0077] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
