Description

Technical Field

[0001] The utility model relates to the technical field of clamping claws, in particular to a suction cup clamping claw mechanism. Background Art

[0002] At present, most thermal conductive sheets are loaded manually. Since the thermal conductive sheet is a relatively thin workpiece, manual assembly easily leads to deformation or damage of the thermal conductive sheet. In addition, in actual production line production, the thermal conductive sheet is usually placed in a thermal conductive sheet carrier. After completing the transfer action of the thermal conductive sheet in the thermal conductive sheet carrier, the thermal conductive sheet loading clamp in the prior art cannot take into account the removal of the empty thermal conductive sheet carrier. It is necessary to manually remove the empty thermal conductive sheet carrier or replace the clamp mechanism with other sizes, which makes the production efficiency low and the labor intensity high.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0029] like Figure 1-Figure 5 As shown, the utility model provides a suction cup clamp mechanism, which includes a mounting base 100 , and the mounting base 100 is connected to a manipulator or a mobile module mechanism 101 so that the suction cup clamp mechanism moves with the manipulator or the mobile module mechanism 101 .

[0030] The clamping jaw linear drive module 200 of the utility model is a linear drive cylinder, the fixed end of the clamping jaw linear drive module 200 is connected to the mounting seat 100, and the driving end thereof is connected to the cylinder support frame 800. The cylinder support frame 800 is a plate similar to an inverted triangle, and its length direction is parallel to the length direction of the suction cup fixing frame 300 described below. The driving end of the clamping jaw linear drive module 200 is connected to one side of the middle end of the cylinder support frame 800, and the fixed end of the first suction cup linear module 900 is fixedly connected to the other side of the middle end of the cylinder support frame 800. The driving end of the first suction cup linear module 900 is connected to the suction cup fixing frame 300. The driving direction of the first suction cup linear module 900 is the same as that of the clamping jaw linear drive module 200. The utility model is that the first suction cup linear module 900 is a linear drive cylinder.

[0031] The clamping claw linear driving module 200 drives the first suction cup linear module 900, the cylinder support frame 800 and the suction cup fixing frame 300 to rise and fall together, and the first suction cup linear module 900 can further drive the suction cup fixing frame 300 to rise and fall.

[0032] The suction cup fixing frame 300 includes an "H"-shaped frame body and four strip-shaped brackets 303. The frame body includes two vertical sides 301 and a crossbeam 302 located between the two vertical sides 301 and vertically connected to the two vertical sides 301. The driving end of the first suction cup linear module 900 is connected to the middle part of the crossbeam 302.

[0033] Two brackets 303 are fixedly connected to each of the two vertical sides 301 at intervals, and the middle parts of the two brackets 303 on each vertical side 301 are fixedly connected to one end of the vertical side 301 along its length direction, and each bracket 303 is horizontally perpendicular to the corresponding vertical side 301. Therefore, each bracket 303 is divided into two symmetrical sections by its corresponding vertical side 301, and the two brackets 303 on the same vertical side 301 and the section of the two brackets 303 located on the same side of the vertical side 301 together constitute a partition of the suction cup fixing frame 300, and each section of each bracket 303 on the partition is symmetrically provided with two first suction cups 400 at intervals, that is, the four first suction cups 400 form a group of first suction cups 400, which suck the same heat conductive sheet 102 together. In order to stably suck the heat conductive sheet 102, the positions of each first suction cup 400 in each group of first suction cups 400 correspond to the positions of the four end points of the heat conductive sheet 102. Therefore, the suction cup fixing frame 300 of the present invention is provided with the above four partitions in total, and can absorb four heat conducting sheets 102 at the same time.

[0034] In actual assembly line production, multiple thermal conductive sheets 102 are usually placed together in a thermal conductive sheet carrier 103. In order to enable the suction cup clamp of the utility model to suck and load the thermal conductive sheets 102 in the thermal conductive sheet carrier 103 and then be compatible with sucking and transporting the thermal conductive sheet carrier 103, the utility model is also provided with a second suction cup linear module 700 and a connecting rod rotating mechanism 500 on the suction cup fixing frame 300 for sucking the thermal conductive sheet carrier 103.

[0035] In the present invention, the heat conducting sheet carrier 103 is a rectangular frame body, and four heat conducting sheet 102 placement areas are arranged along its length direction. The four partition positions on the suction cup fixing frame 300 correspond to the four heat conducting sheet 102 placement areas one by one.

[0036] A second suction cup linear module 700 is fixedly connected to both ends of the cylinder support frame 800 along its length direction, and the length direction of the cylinder support frame 800 is the same as the length direction of the suction cup fixing frame 300. The fixed end of each second suction cup linear module 700 is fixed on the cylinder support frame 800, and the driving end of each second suction cup linear module 700 is connected to a connecting rod rotating mechanism 500. The driving direction of the second suction cup linear module 700 is the same as the driving direction of the first suction cup linear module 900. The second suction cup linear module 700 of the utility model is a linear driving cylinder.

[0037] Each connecting rod rotating mechanism 500 includes a long connecting rod 501 and two L-shaped rotating shaft connecting rods.

[0038] Each of the two top ends of each long connecting rod 501 is provided with an opening slot 504 along the length direction thereof. The opening end of each opening slot 504 is located at the top end of the long connecting rod 501 , and each opening slot 504 is provided with a through hole.

[0039] Each rotating shaft connecting rod comprises a short connecting rod 503 and a cylindrical rotating shaft 502 vertically fixed to the short connecting rod 503 . A second suction cup 600 is fixed to one end of each short connecting rod 503 away from the rotating shaft 502 .

[0040] A rotating shaft 502 is vertically inserted through the two through holes of each long connecting rod 501. At the same time, each rotating shaft 502 is rotated to adjust the angle between each short connecting rod 503 and the long connecting rod 501, so that the second suction cup 600 on each short connecting rod 503 is located within the frame of the thermal conductive plate carrier 103, meeting the requirement of accurately sucking the thermal conductive plate carrier 103, that is, all the second suction cups 600 on the above-mentioned two long connecting rods 501 jointly suck the same thermal conductive plate carrier 103.

[0041] After adjusting the angle between each short connecting rod 503 and the long connecting rod 501 , the open end of each opening slot 504 is locked by a locking member (not shown in the figure), so that the rotating shaft 502 is fixedly clamped in the opening slot 504 .

[0042] The locking piece of the utility model is a bolt.

[0043] In addition to the difference in size, the thermal conductive sheet 102 and the thermal conductive sheet carrier 103 also have a difference in height. In order to enable all the second suction cups 600 on the two long connecting rods 501 to accurately absorb and transport the thermal conductive sheet carrier 103, the middle part of each long connecting rod 501 is connected to the driving end of the above-mentioned second suction cup linear module 700, and each connecting rod rotating mechanism 500 rises and falls with its corresponding second suction cup linear module 700.

[0044] Similarly, in addition to rotating each shaft 502 to adjust the position of the second suction cup 600 on each short link 503, the second suction cup 600 on each short link 503 can also be adjusted to have a suitable height distance with the heat conducting plate carrier 103 by adjusting the length of the through hole of each shaft 502 passing through the long link 501.

[0045] In addition, each of the first suction cup 400 and the second suction cup 600 is a vacuum suction cup, and each vacuum suction cup is connected to a vacuum generator (not shown in the figure) through a pipeline (not shown in the figure).

[0046] The operating principle and process of the utility model are as follows:

[0047] S1, suction and transportation of the thermal conductive sheet 102: the suction cup clamp mechanism of the utility model is driven by the mobile module 101 to move to the storage place of the thermal conductive sheet carrier 103; the clamp linear drive module 200 is controlled to descend, which drives the suction cup fixing frame 300 and the connecting rod rotating mechanism 500 to descend above the thermal conductive sheet carrier 103, and then the first suction cup linear module 900 is controlled to descend, and the suction cup fixing frame 300 is further descended to above the surface of the thermal conductive sheet 102 along with the first suction cup linear module 900, and the vacuum generator connected to the first suction cup 400 is started, and the first suction cup 400 on each partition of the suction cup fixing frame 300 sucks the corresponding thermal conductive sheet 102, and the first suction cup linear module 900 is controlled to rise, and the first suction cups 400 on the four partitions of the suction cup fixing frame 300 synchronously drive the thermal conductive sheet 102 to rise, and the mobile module 101 is started to transport the thermal conductive sheet 102 to the next flow processing position.

[0048] S2, suction and transportation of the thermal conductive sheet carrier 103: after the thermal conductive sheet 102 is transported, the mobile module 101 is started, and the suction cup clamping mechanism is driven by the mobile module 101 to return to the empty thermal conductive sheet carrier 103, and according to the height difference between the thermal conductive sheet carrier 103 and the second suction cup 600, the clamping claw linear driving module 200 is rotated to control the descent, which drives the suction cup fixing frame 300 and the connecting rod rotating mechanism 500 to descend above the thermal conductive sheet carrier 103, or the two second suction cup linear modules 700 are controlled to descend at the same time, and the two connecting rod rotating mechanisms 500 also descend synchronously until the second suction cups on the two connecting rod rotating mechanisms 500 are located above the frame surface of the thermal conductive sheet carrier 103, and the vacuum generator connected to the second suction cup 600 is started, and the second suction cups 600 on the two connecting rod rotating mechanisms 500 suck the thermal conductive sheet carrier 103 at the same time, and the mobile module 101 is started to transport the empty thermal conductive sheet carrier 103 to the empty thermal conductive sheet carrier storage place.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
