Detailed Description

It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

The applicant found in practical operation: the existing sheet arranging machine has the following problems: firstly, the object of the sheet arranging machine is that a plurality of radiating fins are provided, and if one radiating fin is extremely low in discharge efficiency; secondly, if a plurality of radiating fins are arranged together, the distance between the radiating fins is equal when the radiating fins are arranged, but different types have different arrangement intervals, so that the application range of the sheet arranging machine can be enlarged when the radiating fins are applied to the sheet arranging machine of different types, and the equidistant arrangement is ensured.

Therefore, the applicant develops an automatic loading and discharging assembly machine for evaporator cooling fins and a loading and discharging method thereof.

As shown in fig. 1, the automatic feeding and discharging assembly machine for evaporator cooling fins comprises: the device comprises a frame 1, a conveying mechanism 2, an equidistant feeding mechanism 3, a lifting mechanism 4, a clamping mechanism 5 and a vibrating disk 6.

In order to enable the interval of the suction cups 312 to be adjusted equidistantly, as shown in fig. 2, the equidistant feeding mechanism 3 includes: the device comprises a support 301, a Y-axis frame 302, a Y-axis cylinder 303, a first moving block 304, a Z-axis frame 305, a Z-axis cylinder 306, a second moving block 307, a lifting plate 308, a sliding rail 309, a connecting rod 310, a sliding block 311, a suction cup 312, a limiting plate 313, a limiting groove 314, a forward and reverse rotation motor 315, a threaded rod 317 and a threaded sleeve 316.

The bracket 301 is mounted on the frame 1 by bolts and is used for supporting other components. The Y-axis frame 302 is fixed to the support 301 through bolts, the Y-axis cylinder 303 is fixedly mounted at one end of the Y-axis frame 302 through bolts, a first moving block 304 is slidably mounted on the Y-axis frame 302, and the first moving block 304 is used for controlling the rest of components. The Z-axis frame 305 is fixed to the first moving block 304 by bolts, the Z-axis cylinder 306 is fixed to the top of the Z-axis frame 305 by bolts, and a second moving block 307 is slidably mounted on the Z-axis frame 305.

A piston rod of the Y-axis cylinder 303 extends into the Y-axis frame 302 and is fixedly connected to the first moving block 304, and a piston rod of the Z-axis cylinder 306 extends into the Z-axis frame 305 and is fixedly connected to the second moving block 307.

Each upright post is provided with a column body, the limiting plate 313 is arranged on one side of the lifting plate 308 close to the Z-axis cylinder 306 through a conveying assembly, and the limiting plate 313 is provided with a plurality of limiting grooves 314.

In order to satisfy the requirement of equidistant regulation, the distribution of the limiting grooves 314 is as follows:

the extended limiting grooves 314 intersect at a point O, the point O is used as a circle center, any R is used as a radius to make a circle, the positions of the limiting grooves 314 are positions where a plurality of bisectors of the circle are located, and the cylinder is correspondingly located in the limiting grooves 314. The design is to ensure that the distance between adjacent columns is always equal when the limiting plate 313 displaces relative to the lifting plate 308, so as to realize equidistant adjustment and control of the suction cups 312.

The working mode of the equidistant feeding mechanism 3 is as follows: the Z-axis cylinder 306 pushes the lifting plate to move downwards, so that the suction disc 312 sucks the radiating fins on the discharging table; subsequently, the positive and negative motor 315 in the transmission assembly regulates and controls the height of the limiting plate 313, and in the regulating and controlling process, the upright post on the connecting rod 310 is clamped in the limiting groove 314, and the connecting rod 310 is movable in the horizontal direction, so that the connecting rod 310 moves along with the inclined angle of the limiting groove 314, and the limiting groove 314 is in equal division with the same circle, so that the distance between the adjacent cylinders is ensured to be equal, and the distance between the connecting rods 310 can be regulated and controlled. The limiting plate 313 moves upwards, and the distance between the columns is increased; the limiting plate 313 moves downwards, and the distance between the columns is reduced. I.e., the distance between the heat dissipation fins adsorbed on the suction cup 312; the Y-axis cylinder 303 controls the Z-axis frame 305 and the moving block to move forwards integrally, the radiating fins are correspondingly placed in the die, and the steps are repeated in sequence until the radiating fins are discharged.

However, in the above equidistant feeding mechanism 3, if the distance between the dies is small, the distance can be reduced only by moving up the position-limiting plate 313, but during the moving up process, the adjacent sliding blocks 311 can not move up any more and can not reduce the distance, for this reason, the applicant has provided two sets of sliding rails 309 on the lifting plate 308, the two sets of sliding rails 309 are parallel to each other, and the sliding blocks 311 on the two adjacent connecting rods 310 are respectively rubbed with each other on the two sliding rails 309.

Similarly, the stability of the carrier on which the suction cups 312 are disposed is required when the suction cups 312 are used for placing the heat dissipation fins, and the lifting plate is associated with the connecting rods 310 on which the suction cups 312 are disposed, so as to ensure the stability of the lifting plate, where the conveying assembly in transmission connection with the lifting plate includes: a positive and negative rotation motor 315 fixedly installed on the lifting plate 308, a threaded rod 317 in transmission connection with an output shaft of the positive and negative rotation motor 315, and a threaded sleeve 316 matched with the threaded rod 317; the threaded sleeve 316 is fixedly connected with one end of the limit plate 313. The stability of the lifting plate is increased through the threaded rod 317 and the threaded connection, and the interference of the lifting plate on the connecting rod 310 is reduced.

The mechanism is not provided with a mechanism that the sucking disc 312 moves to clamp the radiating fins, so that in order to clamp the radiating fins conveniently and save clamping time, the discharging table of the vibrating disc 6 in the scheme is positioned under the lifting plate 308, the lifting plate is pushed to move downwards only by the Z-axis cylinder 306, the clamping of the radiating fins is directly carried out, the time for the sucking disc 312 to clamp back and forth is saved,
