[0035] Currently, the transfer of materials from the feeding position of the feeder to the processing fixture is done manually. The efficiency of manual operation is low, and it is difficult to avoid defects caused by human error.

[0036] In order to solve the above problems, combined Figure 1 and Figure 2 As shown, this embodiment provides a feeding transfer mechanism, which is mounted above the feeder and the fixture through a bracket. The feeding transfer mechanism includes a grasping device, which is arranged on the bracket. There are at least two groups of grasping devices. Preferably, the grasping device of this embodiment is arranged in two groups, and the two groups of grasping devices are respectively located on two opposite sides of the bracket. With this arrangement, the grasping devices on both sides of the bracket can operate simultaneously without interfering with each other, which improves the efficiency of transferring the feeding to a certain extent.

[0037] In other embodiments, the gripping devices may also be arranged into three, four or even more groups, which is not limited in this embodiment. The specific number may be adaptively adjusted according to the arrangement of the feeder and the fixture, and will not be further elaborated here.

[0038] Specifically, if Figure 1 As shown, the gripping device includes a displacement assembly 1, a negative pressure adsorption assembly 2, and a controller. Each displacement assembly 1 has at least a material retrieving station and a material loading station. The negative pressure adsorption assembly 2 is disposed at the movable end of the displacement assembly 1 and is used to adsorb and feed materials. The displacement assembly 1 is used to drive the negative pressure adsorption assembly 2 to move to the material retrieving station or the material loading station. The controller is electrically connected to the displacement assembly 1 and the negative pressure adsorption assembly 2.

[0039] It can be understood that the controller sends a signal to the displacement assembly 1, the displacement assembly 1 drives the negative pressure suction assembly 2 to move to the material taking station of the feeder, and the feeder is suctioned on the negative pressure suction assembly 2 by vacuumizing, and then the displacement assembly 1 drives the negative pressure suction assembly 2 and the feeder to move to the material loading station together, and stops vacuumizing after the feeder is installed on the jig, the displacement assembly 1 is reset or the next feeder transfer is carried out, so as to change the manual transfer into automatic transfer, realize the precise automatic operation, cooperate with the controller to automatically take and place the feeder throughout the process, improve the work efficiency, in addition, the displacement assembly 1 is provided with at least two groups, the efficiency can be further improved by taking the feeder on both sides, the manpower is reduced, and the human error operation is also reduced.

[0040] As shown in Figure 1 and Figure 2 , the displacement assembly 1 comprises a horizontal moving mechanism and a lifting moving mechanism. The horizontal moving mechanism is arranged on the support and is used to drive the negative pressure suction assembly 2 to move in the horizontal direction, and the lifting moving mechanism is arranged on the output end of the horizontal moving mechanism and is used to drive the negative pressure suction assembly 2 to move in the vertical direction, so as to realize the reciprocating movement in the front-back, left-right and up-down directions, and ensure that the displacement assembly 1 can flexibly drive the negative pressure suction assembly 2 to move, and the flexibility is good.

[0041] Specifically, the horizontal moving mechanism comprises a first driving member and a second driving member. The first driving member is arranged on the support, and the second driving member is arranged on the output end of the first driving member. The first driving member is used to drive the second driving member to reciprocate in the first direction, and the output end of the second driving member reciprocates in the second direction perpendicular to the first direction.

[0042] Preferably, the first driving mechanism comprises a linear motor 11, and the mounting direction of the linear motor 11 extends in the first direction, that is, the output end of the linear motor 11 reciprocates in the first direction. The linear motor 11 can realize very accurate positioning control, has high movement precision and fast response speed.

[0043] Preferably, the second driving member comprises a first air cylinder 12, and the mounting direction of the first air cylinder 12 extends in the second direction, that is, the extension direction of the first air cylinder 12 is arranged in the second direction. The air cylinder has the advantages of simple structure and low maintenance cost.

[0044] Further, the lifting moving mechanism comprises a third driving member. The third driving member is arranged on the output end of the second driving member, and the negative pressure suction assembly 2 is arranged on the output end of the third driving member. The third driving member is used to drive the negative pressure suction assembly 2 to reciprocate in the third direction, and the third direction is a vertical direction.

[0045] Preferably, the third driving member includes a second cylinder 13, and the installation direction of the second cylinder 13 extends in the vertical direction, that is, the telescopic direction of the second cylinder 13 is set in the vertical direction. Similarly, the cylinder has the advantages of simple structure and low maintenance cost.

[0046] In summary, the displacement of the negative pressure adsorption component 2 is achieved through the three-way movement of the linear motor 11 , the first cylinder 12 and the second cylinder 13 .

[0047] like Figure 1 and Figure 2 As shown, the negative pressure adsorption assembly 2 includes an adsorption plate 21, an adsorption head 22, and a vacuum pump (not shown in the figure). The adsorption plate 21 is hollow and has an adsorption cavity inside. The bottom end of the adsorption plate 21 is provided with a plurality of first through holes connected to the interior of the adsorption cavity. Specifically, there are four first through holes in this embodiment, and the four first through holes are respectively located at the four corners of the adsorption plate 21. The number of adsorption heads 22 is consistent with the number of first through holes, so there are also four adsorption heads 22. The connection end of the adsorption head 22 is detachably connected to the first through hole and is connected to the adsorption cavity.

[0048] More specifically, a screw hole 24 is provided on the side of the adsorption plate 21, one end of the screw hole 24 is connected to the first through hole, and a bolt 25 is threadedly connected to the inner thread of the screw hole 24, the end of which is tightly pressed against or connected to the end of the adsorption head 22. By inserting one end of the adsorption head 22 into the first through hole, and then screwing one end of the bolt 25 into the screw hole 24 until one end of the bolt 25 presses the adsorption head 22 tightly or one end of the bolt 25 is threaded into the corresponding threaded hole of the adsorption head 22, the detachable connection of the adsorption head 22 can be achieved, and installation and disassembly are convenient.

[0049] In other embodiments, the number of first through holes and adsorption heads 22 may not be equal. A plug may be provided in the first through hole where no adsorption head 22 is provided to seal the first through hole to ensure the normal operation of the vacuum pump. The number of first through holes and adsorption heads 22 may also be one, two, three, five or even more. This embodiment does not make any specific restrictions on this, and it can be set according to the shape and size of the feed.

[0050] It should be noted that the bottom end of the adsorption plate 21 is the end face facing the feeder and the fixture, and in other embodiments it may also be the side or top end of the adsorption plate 21 .

[0051] In order to avoid the wiring harnesses of the feeding transfer mechanism from getting tangled together, which is not conducive to movement or maintenance, such as Figure 2 As shown, a drag chain 3 is provided on the bracket, and the wiring harnesses of the feeding transfer mechanism are integrated into the drag chain 3.

[0052] In addition, a deceleration valve 23 connected to the adsorption cavity is provided on the adsorption plate 21, and the pipeline of the vacuum pump is connected to the deceleration valve 23. By adjusting the deceleration valve 23, the speed and pressure of the airflow can be controlled to reduce the damage to the negative pressure adsorption component 2 or the feed caused by inertial impact and pressure fluctuations of the vacuum pump.

[0053] Now combined Figure 1 and Figure 2 The operation process of the feeding transfer mechanism is further described in detail:

[0054] First, the linear motor 11, the first cylinder 12 and the second cylinder 13 are kept in the initial position;

[0055] Then, the controller sends a displacement signal to the linear motor 11, the first cylinder 12 and the second cylinder 13. The linear motor 11, the first cylinder 12 and the second cylinder 13 drive the negative pressure adsorption assembly 2 to move to the material picking station. The vacuum pump starts and uses negative pressure to adsorb the material from the material picking station onto the adsorption head 22.

[0056] Secondly, the linear motor 11, the first cylinder 12 and the second cylinder 13 drive the negative pressure adsorption component 2 to move to the loading station, the vacuum pump is turned off, and the feed remains at the loading station;

[0057] Finally, the linear motor 11, the first cylinder 12 and the second cylinder 13 return to their initial positions.

[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
