To solve the above problems, the following description is made with reference to the accompanying drawings:

the utility model provides a positioner 5 for tray, including frame 1, lifting mechanism 2, the translation body 3, relocation mechanism 4 and positioner 5.

The frame 1 comprises a quadrilateral body 11, a first supporting part and a second supporting part, wherein the quadrilateral body 11 is formed by connecting two long cross beams and two short cross beams end to end. The bottom of the quadrilateral body 11 is fixedly connected with a plurality of vertically downward foot rests 14 which are placed on the ground and used for supporting the weight of the quadrilateral body 11. A first support mechanism 12 and a second support mechanism 13 are arranged side by side above the quadrilateral body 11. The first supporting mechanism 12 includes a plurality of first vertical posts 121 fixedly connected to a long beam at one end of the quadrilateral body 11, and the first vertical posts 121 are parallel to each other. The other ends of the first vertical columns 121 are jointly and fixedly connected with a first beam 122. The second support mechanism 13 includes a plurality of second uprights 131 higher than the first uprights 121. A plurality of second upright posts 131 are also vertically fixedly connected to the other long beam of the quadrilateral body 11. The second beams 132 are fixed on the second columns 131, and the first beams 122 are parallel to the second beams 132. The frame 1 is a supporting part of the positioning device 5 for the tray, and supports the weight of the whole positioning device 5.

The lifting mechanism 2 is a driving mechanism. The lifting mechanism 2 is connected to the first beam 122 and includes a lifting cylinder 21, a guide rod 22, a first movable block 23 and a second movable block 24. First slide rail is two, and equal level is fixed at the both ends of first crossbeam 122, and two first slide rails all extend along first crossbeam 122 length direction. The first movable block 23 and the second movable block 24 are respectively connected to two first slide rails at two ends of the first beam 122 in a sliding manner, and slide along the first slide rails. The guide bar 22 is an elongated metal bar, and both ends of the guide bar are fixed to the first movable block 23 and the second movable block 24, respectively, so that the first movable block 23 and the second movable block 24 can move synchronously. The output end of the lifting cylinder 21 is connected to a movable part formed by combining the first movable block 23, the second movable block 24 and the guide rod 22. The lifting cylinder 21 is a power output part and is used for pushing the movable part to move horizontally. The lifting cylinder 21 drives the first movable block 23 or the second movable block 24 to move along the first slide rail in the horizontal direction. The first movable block 23 and the second movable block 24 are both provided with a sliding groove 231, and the sliding groove 231 has an inclined surface 232 which inclines upwards.

The translation body 3 is used for connecting the battery workpiece and lifting the battery workpiece to a specified position under the driving of the lifting mechanism 2 so as to facilitate the next working procedure on the automatic line. The translation body 3 is connected to second slide rails provided on the side walls of the second support mechanism 13 (between the second vertical columns 131 located below both ends of the second cross member 132), respectively. The second slide rail includes two, is located second crossbeam 132 both ends, and all vertical downwards. Two second slide rails are respectively connected with a translation body 3 in a sliding way. The translation body 3 comprises a lifting frame 311 and a slide block 312, wherein one end of the slide block 312 is fixedly connected with the bottom of the lifting frame 311, and the other end is connected in the sliding chute 231. The two translational bodies 3 on the second rail 133 are the first translational body 313 and the second translational body 323, respectively. When the first movable block 23 and the second movable block 24 perform the horizontal synchronous movement, the first movable block 23 drives the sliding block 312 in the sliding slot 231 to slide along the inclined plane 232 in the sliding slot 231, and drives the first movable body 313 to move up and down. Likewise, second movable block 24 drives second translational body 323 to move up and down in the same manner. When first movable block 23 or second movable block 24 drives each corresponding movable body 3 to move vertically in synchronization with each other, first movable body 313 and second movable body 323 are relatively independent from each other (first movable body 313 and second movable body 323 are not fixedly connected by a connecting member) and do not interfere with each other. Even if the lifting mechanism 2 has low precision and cannot ensure that the first and second moving bodies 313 and 323 lift completely and synchronously, the first and second moving bodies 313 and 323 cannot be jammed or damaged due to the influence of torque and lateral force caused by the difference of the lifting heights of the first and second moving bodies 313 and 323.

The first flat moving body 313 and the second flat moving body 323 are both fixedly connected with a floating mechanism 4, and the two floating mechanisms 4 are independently driven by the corresponding flat moving bodies 3 to move up and down.

The head area of the ball 42 extends out of the housing 41, and a spring is arranged below the ball 42 and used for supporting the ball 42 to be pressed down into the housing 41 and then reset. The part of the ball 42 extending out of the housing 41 is supported at the bottom of the battery workpiece, and the bottom of the battery workpiece is ensured not to be suspended even if the heights of the two sides of the battery workpiece have a little difference because the bottom of the ball 42 is supported by a spring. Since the floating mechanism 4 is fixedly connected to both the first and second flat bodies 313 and 323, the height difference between the first and second flat bodies 313 and 323 can be effectively eliminated, and the battery workpiece is not deflected in the vertical direction during movement.

A positioning device 5 is fixedly mounted on the first translation body 313, and the positioning device 5 includes a positioning rod 51 and a telescopic cylinder connected to the positioning rod 51. The positioning rod 51 is driven by the telescopic cylinder to penetrate into the battery workpiece positioning hole, so that the battery workpiece is aligned and positioned in the vertical moving process, and the battery workpiece is prevented from deflecting in the lifting process.

The use method of the positioning device 5 for a tray is S1: placing the bottom of the battery workpiece on the ball 42 of the floating mechanism 4 at a low station; s2: the telescopic cylinder drives the positioning rod 51 to ascend and penetrate into a positioning hole of the battery workpiece, so that the battery workpiece is positioned; s3: the lifting cylinder 21 pushes the first movable block 23 to slide along the first slide rail. S4: the sliding blocks 312 in the first movable block 23 and the second movable block 24 slide along the inclined plane 232 of the sliding slot 231, so as to drive the first movable body 313 and the second movable body 323 to move up and down, and further convey the floating mechanism 4 on the first movable body 313 and the second movable body 323 and the battery workpiece connected with the floating mechanism 4 to a high station, and continue to be processed from the next process.
