Description

[Technical field]

[0001] The invention relates to an automatic radiator feeding machine and a feeding method thereof. [Background technology]

[0002] The heat sink on the gasoline tincture needs to be folded on the folding machine before it can be installed and used. Figure 1 and Figure 2 As shown, the heat sink 3 on the electric oil tincture has a first concave portion 301 and a second concave portion 302 on both sides, respectively. When a plurality of heat sinks 3 are stacked into a pile, one side is higher and the other side is lower. On the higher side, the first concave portion 301 is partially inserted into the lower heat sink 3; on the lower side, the second concave portion 302 is completely sunk into the lower heat sink; when grabbing the top heat sink 3, it is necessary to first lift the higher side of the heat sink 3 so that the higher side is separated from the lower heat sink; if the entire heat sink 3 is lifted at the same time, the higher side of the heat sink 3 will bring up the lower heat sink, so grabbing the top heat sink from a pile of heat sinks requires certain skills, and general grabbing devices cannot quickly complete it. The existing technology is to grab one by one manually, but this method is relatively inefficient, and manually putting the heat sink into the folding machine is dangerous.

[Specific implementation method]

[0028] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0029] An automatic heat sink feeding machine includes a base 1, a turntable 2 and a driver for driving the turntable 2 to rotate are provided on the base 1, a station for stacking multiple heat sinks 3 is provided on the turntable 2, a bracket 9 is provided on the base 1, a linear module 5 is provided on the bracket 9, and a suction device 4 is provided on the linear module 5, which is driven by the linear module 5 to move horizontally, sucks a heat sink 3 on one of the stations and transfers it to the folding machine 10.

[0030] Furthermore, the driver is a four-station driver. The linear module 5 includes a servo motor 501 and a screw mechanism, which can accurately transport the suction device 4 to a specified position.

[0031] like Figure 3 and Figure 4 As shown, the automatic heat sink feeding machine is installed next to the folding machine 10, and the base 1 is installed on the ground. The turntable 2 is provided with four workstations. Every time the turntable 2 rotates 90 degrees, the next workstation is rotated to the bottom of the suction device 4. Each workstation is provided with at least two stacks of heat sinks 3. After grabbing a stack of heat sinks 3, the linear module 5 drives the suction device 4 to move to the top of another stack of heat sinks 3 to grab the stack of heat sinks. Therefore, it is only necessary to manually pile up the heat sinks 3 on the turntable 2, and no manual supervision is required, and there is no need to manually put the heat sink 3 into the folding machine, which can greatly improve the processing efficiency, reduce labor costs, and avoid the occurrence of safety accidents.

[0032] A limiting device 6 for limiting the position of the heat sink 3 is provided at each station on the turntable 2 to prevent the heat sink 3 from being deviated or misaligned when a large number of heat sinks 3 are stacked.

[0033] The limiting device 6 includes a plurality of vertical limiting rods 601 arranged outside the heat sink 3, at least five limiting rods 601 are respectively arranged on the left and right sides of each station, and a connecting plate 602 for connecting the limiting rods 601 is arranged at the upper end of the limiting rods 601, and the heat sink 3 is installed between two adjacent connecting plates 602. The connecting plate 602 connects the limiting rods 601 of two adjacent stations to play a reinforcing role. The topmost heat sink 3 of the stack is flush with the connecting plate 602.

[0034] The base 1 is provided with a lifting device 7 for lifting the heat sink 3 to a specified height for the suction device 4 to suck. The lifting device 7 includes a lifting cylinder 701 provided below the base 1 and a sensor 702 provided below the linear module 5. The suction device 4 can only suck the heat sink 3 at a specified height. Therefore, each time a heat sink 3 is sucked away, when the sensor 702 cannot sense the heat sink 3, it will feedback control the lifting cylinder 701 to lift once to add a heat sink 3.

[0035] like Figure 5 and Figure 6As shown, the suction device 4 includes a first fixed plate 401 fixed on the linear module 5, and a driving cylinder 402 is provided on the first fixed plate 401. The piston rod of the driving cylinder 402 extends downward, and the piston rod of the driving cylinder 402 is fixedly connected to an upper mounting plate 403. First linear bearings 404 are respectively provided on opposite sides of the upper mounting plate 403, and a first connecting rod 405 is provided on the first linear bearing 404, that is, the first connecting rod 405 can move up and down relative to the first linear bearing 404, and fixed blocks 406 are respectively hinged on the other two opposite sides of the upper mounting plate 403, and the fixed block 406 has a second linear bearing built in it, and a second connecting rod 407 and a third connecting rod 408 are respectively installed on the two second linear bearings, that is, the second connecting rod 407 and the third connecting rod 408 can move up and down relative to the second linear bearing.

[0036] A stopper 409 is provided on one of the fixed blocks 406, the second connecting rod 407 passes through the stopper 409, a stop ring 410 is fixed on the upper part of the second connecting rod 407, an extension rod 411 is fixedly connected to the upper part of the third connecting rod 408, a second fixing plate 412 is provided on the other fixed block 406, a clamping cylinder 413 capable of clamping the extension rod 411 is provided on the second fixing plate 412, a clamping claw is provided on the clamping claw cylinder 413, and the clamping claw cylinder 413 can drive The clamping claw clamps the extension rod 411, and a third fixed plate 414 is provided on the extension rod 411. A buffer 415 is provided vertically downward on the third fixed plate 414. A lower mounting plate 416 is hinged at the lower end of the first connecting rod 405, and the lower ends of the second connecting rod 407 and the third connecting rod 408 are also hinged on both sides of the lower mounting plate 416 respectively. The first connecting rod 405 is hinged on both sides of the middle part of the lower mounting plate 416, and a plurality of electromagnets 417 are provided on the bottom surface of the lower mounting plate 416.

[0037] Furthermore, there are four electromagnets 417, which are respectively arranged at the four corners of the lower mounting plate 416. The driving cylinder 402 is a three-rod cylinder.

[0038] The structure of the suction device 3 is the key to the present invention. After sucking the heat sink 3, the higher side of the heat sink 3 can be lifted first. Because after sucking the heat sink 3, the clamping cylinder 413 clamps the extension rod 411, the third connecting rod 408 rises together with the piston rod of the driving cylinder 402, and the second connecting rod 407 does not rise immediately, but rises only after the block 409 hits the retaining ring 410. Subsequently, the clamping cylinder 413 releases the extension rod 411, and the third connecting rod 411 drops relative to the second linear bearing, causing the lower mounting plate 416 to swing to the horizontal, and the buffer 415 will buffer when it hits the fixing block 406 below, preventing the mounting plate 416 from vibrating violently and causing the heat sink 3 to fall.

[0039] The present invention also requests protection for a method for feeding the heat sink automatic feeder as described above, wherein a plurality of stacks of heat sinks 3 are placed on each station of the turntable 2, the linear module 5 drives the suction device 4 to move to the top of a stack of heat sinks 3, and the driving cylinder 402 drives the upper mounting plate 403 and the lower mounting plate 416 to move downward, one side of the stacked heat sinks 3 is higher and the other side is lower, and the side of the lower mounting plate 416 equipped with the third connecting rod 408 stops moving downward after reaching the higher side of the heat sink 3, but the side of the upper mounting plate 403 and the lower mounting plate 416 equipped with the second connecting rod 407 continues to move downward, so that the third connecting rod 408 and the two first connecting rods 405 gradually tilt and move upward relative to the linear bearing. After the lower mounting plate 416 is fitted with the heat sink 3, the second connecting rod 407 moves upward a short distance relative to the fixed block 406, and the piston rod of the driving cylinder 402 stops moving downward;

[0040] The electromagnet 417 on the lower mounting plate 416 sucks the top heat sink 3, and the clamping claw cylinder 413 drives the clamping claw to clamp the extension rod 411, and the piston rod of the driving cylinder 402 retracts upward, driving the upper mounting plate 403 to rise, and the third connecting rod 408 rises together with the upper mounting plate 403, and the second connecting rod 407 does not rise before the stopper 409 hits the retaining ring 410, so that the side of the lower mounting plate 416 equipped with the third connecting rod 408 rises first, driving the top heat sink 3 to rise first, and after the heat sink 3 is separated from the lower heat sink 3, the clamping claw cylinder 413 releases the extension rod 411, and the upper mounting plate 403 continues to rise, and the side of the lower mounting plate 416 equipped with the third connecting rod 408 drops relative to the fixed block 406 until the buffer 415 hits the fixed block 406 below, and the lower mounting plate 416 is horizontal at this time;

[0041] The lower mounting plate 416 is driven to rise, and after the stopper 409 hits the stopper ring 410, the second connecting rod 407 is driven to rise by the stopper 409, and the linear module 5 transports the heat sink 3 sucked on the lower mounting plate 416 to the folding machine 10 for folding;

[0042] The linear module 5 drives the suction device 4 back to the top of the heat sink 3, and at the same time the lifting cylinder 701 is actuated to add a heat sink 3. The suction device 4 repeats the above action to suck another heat sink 3 and transfer it to the folding machine 10 for folding. After the heat sink 3 stacked on one station is processed, the turntable 2 rotates 90 degrees, and the suction device 4 sucks the heat sink 3 on the next station and transfers it to the folding machine 10 until the heat sink 3 on all stations is processed.

[0043] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should all fall within the protection scope of the present invention.
