During the uninstallation, present article are all on the assembly line, for example equipment such as conveyer belt receives some restrictions of assembly line occasionally, uninstallation equipment can not be too close to, for this reason, this patent is equipped with local degree of freedom, that is, the support arm 3's that backup pad 6 is relative slip, it is just near backup pad 6 reaches the assembly line, place (or uninstallation) article place district 61 back at article, backup pad 6 slides to main arm 1 direction, kept away from the assembly line, at this moment, this patent again rotates, operation such as lift, do not receive the restriction of assembly line, it is more convenient.

The working principle is as follows:

at the beginning, move this patent to the assembly line annex, make slewing bearing 18 rotate, make main arm 1, support arm 3 all face the assembly line, through the length of adjustment drive anti-falling pole 5, the height of adjustment backup pad 6 can cooperate with the assembly line, at this moment, relies on self-locking mechanism, also can keep the stability of parallelogram four-bar linkage under the condition of energy consumption not.

The piston end of the driving cylinder 7 extends out, so that the rail 31 of the supporting plate 6 slides and is closer to the assembly line, when the supporting plate 6 reaches a proper position, the piston end of the driving cylinder 7 stops moving, and at the moment, the article is transferred to the article placing area 61 from the assembly line through external force (force except the product in the patent, including the inertia force of the article).

And then the piston end of the driving cylinder 7 contracts to enable the supporting plate 6 to be far away from the production line, when the photoelectric switch 14 senses the baffle plate 15, the article placing area 61 and the articles are both positioned between the two clamping blocks 12, at the moment, the photoelectric switch 14 sends a signal to the PLC, and the PLC sends a signal to command the piston end of the driving cylinder 7 to stop moving.

PLC signals again and commands first power part 10 to rotate, thereby drive screw 9 rotates for slide rail 8, drive screw 9 drives two sliders 11 and slides, the screw thread turning at drive screw 9 both ends is opposite, two sliders 11 are close to each other on slide rail 8 simultaneously, two grip blocks 12 begin to add and hold article (because article are between two grip blocks 12 this moment), signal after grip block 12 force transducer reaches the ultimate value, PLC gives first motor PLC signals again and commands first power part 10 to stop, at this moment, rely on self-locking mechanism, also can keep the reasonable additional of material under the condition of not consuming energy and hold.

When the slewing bearing 18 is rotated to enable the main arm 1 and the supporting arm 3 to face the target equipment, the height of the supporting plate 6 can be adjusted to be matched with the height of the target equipment by adjusting the length of the driving anti-falling rod 5, and at the moment, the stability of the parallelogram four-bar linkage can be kept under the condition of not consuming energy by virtue of the self-locking mechanism.

The piston end of the driving cylinder 7 extends out again, so that the support plate 6 slides along the rail 31 to be closer to the target device, and when the support plate 6 reaches a proper position, the piston end of the driving cylinder 7 stops moving.

The first power part 10 of reverse drive to drive screw 9 rotates for slide rail 8, and two sliders 11 of drive screw 9 drive slip, and the screw thread turning at drive screw 9 both ends is opposite, and two sliders 11 keep away from each other simultaneously on slide rail 8, and article are loosened to two grip blocks 12, and at this moment, place the district 61 with article through external force (the power beyond this patent product) and shift to the target equipment on with article.

Thus, the loading and unloading (transfer) of the article is completed.

The invention has the characteristics that:

according to the invention, the driving anti-falling rod 5 can drive the lifting arm 2 to rotate in a reciprocating manner, under the action of the parallel rod 4, the clamping assembly on the supporting arm 3 is always kept in a horizontal state, so that an article clamped on the clamping assembly is always kept horizontal, and when the main arm 1 rotates, the article is also in a horizontal state, so that the article has higher stability under the clamping of the clamping assembly, is not easy to fall off, and improves the use reliability; the lifting device can lift and lower articles, reduces the amount of manual labor, and is simple to operate and convenient to use.

See the prior art for additional details.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the invention, and these should also be considered as the protection scope of the present invention.
