The supporting block 44 is provided with a first flow channel connected with the first suction port 4401. The first flow channel is connected with an external vacuum suction device.

[0043] As shown in Figures 2-4 , the bottom distributing mechanism 4 further comprises a plug-in block 45 connected to the push block 43; the supporting block 44 is plugged with the push block 43 through the plug-in block 45, which facilitates quick replacement of the supporting block 44 to adapt to the distributing operation of different finished blades 9.

Through the setting of the second limiting block 46 and the U-shaped block 47, the moving distance of the push block 43 and the supporting block 44 is limited to ensure that the grabbing mechanism 5 can stably grab the finished blade 9.

[0045] As shown in Figure 1 ,Figure 2 、 Figure 8 and Figure 9 As shown in FIG. 11 and FIG. 12, the grabbing mechanism 5 comprises a second mounting frame 51 connected to the first mounting frame 11; the second mounting frame 51 is connected with an electric sliding rail 52; the electric sliding rail 52 is connected with a sliding block 53; the sliding block 53 is connected with a second rail 54; the second rail 54 is connected with a second electric sliding block 55; the second electric sliding block 55 is connected with a second connecting block 56; the second connecting block 56 is detachably connected with a grabbing head 57; the grabbing head 57 is provided with a plurality of second suction ports 5701, third suction ports 5702, two second escape ports 5703 and a first positioning block 5704; the first positioning block 5704 is located between the two second escape ports 5703, and the first positioning block 5704 and the second escape ports 5703 are on the same straight line; the third suction port 5702 is rectangular, which improves the suction area; the grabbing head 57 is provided with a second flow channel communicated with the second suction port 5701 and the third suction port 5702, and the second flow channel is connected with an external vacuum suction equipment; the connection between the first positioning block 5704 and the grabbing head 57 is provided with a pressure sensor; the outer circumferential surface of the end of the first positioning block 5704 away from the grabbing head 57 is inclined to the middle; the finished blade 9 is grabbed through the second suction port 5701 and the third suction port 5702, and the stability of the butt joint between the finished blade 9 and the grabbing head 57 is ensured through the first positioning block 5704.

[0046] Specifically, the lowermost finished blade 9 in the restriction space formed by the first connecting plate 31, the first connecting block 32 and the first limiting block 33 is in contact with the upper surface of the supporting block 44, the hollow part on the finished blade 9 is opposite to the first avoiding opening 4402, and the external vacuum suction equipment (not shown in the figure) provides suction force for the first suction opening 4401 to tightly adsorb the lowermost finished blade 9; when the bottom material mechanism 4 operates, the first electric sliding block 42 drives the push block 43 and other parts to move on the first track 41 to the grabbing mechanism 5, in the process, the finished blade 9 at the lowermost position of the restriction space is driven by the supporting block 44 to gradually separate from the finished blade 9 adjacent to it above, the push block 43 limits the remaining finished blades 9, when the finished blade 9 is brought to be opposite to the grabbing head 57, the second electric sliding block 55 drives the second connecting block 56 and the grabbing head 57 to descend on the second track 54, at this time the grabbing head 57 is in contact with the surface of the finished blade 9, the external vacuum suction equipment stops providing suction force for the first suction opening 4401, the external vacuum suction equipment provides suction force for the second suction opening 5701 and the third suction opening 5702 to adsorb the finished blade 9, then the second electric sliding block 55 drives the second connecting block 56 and the grabbing head 57 to reset on the second track 54, at the same time the electric sliding rail 52 drives the sliding block 53 and the components connected with the sliding block 53 to move to the direction of the disc mechanism 6, after moving to the limit, the second electric sliding block 55 drives the second connecting block 56 and the grabbing head 57 to descend on the second track 54, after descending to the limit, the external vacuum suction equipment stops providing suction force for the second suction opening 5701 and the third suction opening 5702, so that the finished blade 9 is placed on the disc mechanism 6 to wait for carrying, then the grabbing head 57 is reset to prepare for the next finished blade 9 grabbing operation; after the finished blade 9 on the supporting block 44 is grabbed by the grabbing head 57, the first electric sliding block 42 drives the push block 43 and other parts to reset on the first track 41 to prepare for the next material distribution operation, after the push block 43 and other parts reset, the finished blades 9 in the restriction space will descend, at this time the finished blade 9 at the lowermost position will be in contact with the supporting block 44.

[0047] When the grabbing head 57 descends to grab the finished blade 9 on the supporting block 44, the first positioning block 5704 of the grabbing head 57 will first be inserted into the first avoiding port 4402 through the hollow part in the middle of the finished blade 9, and the finished blade 9 is positioned. If the pressure sensor on the first positioning block 5704 monitors the pressure change during the positioning process, it indicates that the position of the finished blade 9 deviates from the grabbing head 57. At this time, the pressure sensor controls the external vacuum suction device to stop providing suction force for the first suction port 4401. Because the outer circumferential surface of the first positioning block 5704 far away from the end of the grabbing head 57 is inclined to the middle, that is, after the finished blade 9 loses the adsorption and fixation of the first suction port 4401, the position of the finished blade 9 is adjusted under the action of the descending first positioning block 5704 and the inclined outer circumferential surface to the middle, to ensure the stable grabbing of the grabbing head 57, and to ensure the stable and accurate placement. It is noted that the position of the finished blade 9 falling on the supporting block 44 is only slightly offset under the limitation of the limiting space during the above positioning process; after the above first positioning block 5704 adjusts the position of the finished blade 9, if the pressure sensor on the first positioning block 5704 still monitors the pressure change, it indicates that the size of the hollow part in the middle of the finished blade 9 is a problem. At this time, the pressure sensor controls the buzzer (not shown in the figure) to alarm, prompting the operator to take out the unqualified finished blade 9, and the pressure sensor controls the second electric sliding block 55 to drive the connected components to reset; the above alarm trigger is that the pressure sensor continuously monitors the pressure change for 3-5 seconds.

[0048] The control logic of the above pressure sensor is: after the pressure sensor is triggered, the pressure sensor transmits the signal to the signal receiver through the signal transmission device. After being received and identified by the signal receiver, the corresponding components (external vacuum suction device, buzzer) are controlled to open and close by the PLC controller. In the subsequent description, the basic control logic of the pressure sensor is consistent except for the components controlled by the PLC controller.

[0052] Specifically, when the bottom material mechanism 4 is in operation, the third electric sliding block 62 drives the second connecting plate 63 and the components connected to the second connecting plate 63 to move along the third track 61 to the right until the first protruding part 6404 of the rightmost tray 64 on the second connecting plate 63 moves to the transverse path of the grabbing head 57; during the process of placing the finished blade 9 grabbed by the grabbing head 57 on the tray 64, the first positioning block 5704 is inserted into the third avoiding port 6402, the second positioning block 6403 passes through the hollow part on the side of the finished blade 9 and enters the second avoiding port 5703, when the grabbing head 57 is lowered to the limit, the control peripheral vacuum suction device stops providing suction force for the second suction port 5701 and the third suction port 5702, and at the same time, the control peripheral vacuum suction device provides suction force for the fourth suction port 6401 of the first protruding part 6404 of the rightmost tray 64 on the second connecting plate 63 to adsorb the finished blade 9, when the finished blade 9 is placed on the first protruding part 6404 of the rightmost tray 64 on the second connecting plate 63, and the grabbing head 57 is reset for the next grabbing operation, the third electric sliding block 62 drives the second connecting plate 63 and the components connected to the second connecting plate 63 to continue moving along the third track 61 to the right, so that the next protruding part 6404 of the rightmost tray 64 on the second connecting plate 63 moves to the transverse path of the grabbing head 57, preparing for the next material loading operation.

[0053] During the above process of inserting the first positioning block 5704 into the third avoiding port 6402, if the pressure sensors on the first positioning block 5704 and the second positioning block 6403 both monitor pressure changes, it indicates that the first positioning block 5704 is not aligned with the third avoiding port 6402, at this time, the pressure sensors control the third electric sliding block 62 to drive the second connecting plate 63 and the components connected to the second connecting plate 63 to fine-tune left and right along the third track 61 until the first positioning block 5704 is aligned with the third avoiding port 6402, ensuring that the finished blade 9 is stably placed on the tray 64, avoiding placement deviation problems.

[0054] During the above process of aligning the first positioning block 5704 with the third avoiding port 6402 and the second positioning block 6403 passing through the hollow part on the side of the finished blade 9 and entering the second avoiding port 5703, if the pressure sensor on the second positioning block 6403 monitors pressure changes, it indicates that there is a size problem with the hollow part on the side of the finished blade 9, at this time, the pressure sensor controls the second electric sliding block 55 to drive the components connected thereto to reset, controls the electric sliding rail 52 to drive the components connected thereto to reset, and controls the buzzer to alarm, prompting the operator to take out the unqualified finished blade 9.

[0055] After all the trays 64 on the second connecting plate 63 are filled with finished blades 9, the second connecting plate 63 is opposite to the carrying frame 78, the suction cups 710 are opposite to the corresponding finished blades 9, at this time, the operation of the bottom feeding mechanism 4 and the grabbing mechanism 5 is stopped, the external multi-axis moving frame (not shown in the figure) drives the first connecting rod 71 and the components connected by the first connecting rod 71 to descend, so that the same group of suction cups 710 contacts the front and rear ends of the finished blades 9, then the external vacuum suction device is controlled to provide suction force for the suction cups 710 to adsorb the finished blades 9, the external vacuum suction device is controlled to stop providing suction force for the fourth suction port 6401, then the external multi-axis moving frame drives the first connecting rod 71 and the components connected by the first connecting rod 71 to move into the injection mold for feeding operation; after the placement is completed, the external multi-axis moving frame drives the first connecting rod 71 and the components connected by the first connecting rod 71 to reset for the next placement work; at this time, the bottom feeding mechanism 4 and the grabbing mechanism 5 continue to operate to place the finished blades 9 from the first protruding part 6404 of the leftmost tray 64 on the second connecting plate 63.

[0056] The feeding operation is specifically: after the external multi-axis moving frame drives the rotating carrying mechanism 7 and the finished blades 9 to move to the specified position in the injection mold, the external vacuum suction device is controlled to stop providing suction force for the suction cups 710.

[0057] In summary, through the setting of the spring feeding bin 3, the bottom feeding mechanism 4, the grabbing mechanism 5, the tray mechanism 6 and the rotating carrying mechanism 7, batch automatic placement operation of the finished blades 9 is realized, the problems of tedious, difficult, inaccurate and low efficiency of manual placement operation of the operator are solved, the placement efficiency is ensured, the placement accuracy is ensured, and the quality after injection molding is ensured.

[0058] When the external multi-axis moving frame drives the first connecting rod 71 and the components connected by the first connecting rod 71 to move into the injection mold for feeding operation, if the injection mold is placed in a vertical state, the output end of the electric push rod 72 is controlled to drive the rack 73 to descend and rotate the transmission connecting seat 76 through the tooth part 7601, after the output end of the electric push rod 72 extends to the limit, the connecting seat 76 drives the connecting frame 77 and the components connected by the connecting frame 77 to change from a horizontal state to a vertical state, so as to adapt to the placement of the finished blades 9 in the vertical state of the injection mold, and improve the adaptability of the present application.

[0059] In the process of lowering the first connecting rod 71 and the components connected by the first connecting rod 71 driven by the external multi-axis moving frame, the positioning operation is performed by inserting the positioning pin 79 into the positioning hole 65. If the pressure sensor on the positioning pin 79 detects a pressure change during the positioning process, it indicates that there is a positional deviation between the second connecting plate 63 and the carrying frame 78, and there is a positional deviation between the suction cup 710 and the finished blade 9. Therefore, when the pressure sensor detects a pressure change, the pressure sensor controls the third electric sliding block 62 to drive the second connecting plate 63 and the components connected on the second connecting plate 63 to fine-tune left and right along the third track 61, so as to ensure that the rotary carrying mechanism 7 stably grabs the finished blade 9 and stably places the finished blade 9 in the injection mold.

[0060] As shown in Figure 5 and Figure 7 The auxiliary mechanism 8 includes a plurality of matrix distributed rotating rollers 82 connected to the first limiting block 33. All rotating rollers 82 are commonly connected with a rectangular conveying belt 81, which is arranged in the accommodating groove of the first limiting block 33. The upper surface of the rectangular conveying belt 81 is flush with the upper surface of the first limiting block 33. The side length of the rectangular conveying belt 81 is one third of the length of the first limiting block 33. One side of the rectangular conveying belt 81 is flush with the flat wall surface of the first limiting groove 34. Four direct drive motors 83 are fixedly connected to the wall surface of the accommodating groove of the first limiting block 33. The output end of the direct drive motor 83 is fixedly connected with the rotating roller 82 located at the four corners in the rectangular conveying belt 81.

[0061] Specifically, in the process of placing the finished blade 9 into the limiting space composed of the first connecting plate 31, the first connecting block 32 and the first limiting block 33 by the operator or the external conveying mechanism, taking the left-to-right view as the perspective reference, the direct drive motor 83 connected to the first limiting block 33 on the front side of the first connecting plate 31 drives the rectangular conveying belt 81 to rotate counterclockwise through the rotating roller 82, and the direct drive motor 83 connected to the first limiting block 33 on the rear side of the first connecting plate 31 drives the rectangular conveying belt 81 to rotate clockwise through the rotating roller 82, so as to actively downward convey the finished blade 9 entering the limiting space, avoiding the upward and downward warping of the finished blade 9 leading to the material jamming problem.

[0062] Specifically, the detachable connection of the first limiting block 33 and the first connecting block 32 is to facilitate the maintenance of the components such as the rectangular conveying belt 81 connected to the first limiting block 33.

The scope of the following claims is to be given the broadest interpretation to encompass all variations and equivalents.
