[0038] Referring to Figures 1 to 10 In order to better understand the raw leather rear cover injection molding feeding and discharging device 10, the following further explains the raw leather rear cover injection molding feeding and discharging device 10:

[0039] The raw leather rear cover injection molding feeding and discharging device 10 of an embodiment is fixedly installed at the power output end of the telescopic turnover mechanism of the injection molding machine manipulator. The raw leather rear cover injection molding feeding and discharging device 10 includes a feeding mechanism 200 and a discharging mechanism 300. The feeding mechanism 200 includes a base plate 210 and a suction assembly 220; one side of the base plate 210 is connected to the telescopic turnover mechanism 100, and the suction assembly 220 includes a suction plate 2210 and a plurality of first negative pressure nozzles 2220; the suction plate 2210 is arranged on the other side of the base plate 210, and the suction plate 2210 is provided with a suction surface 2212 for abutting against the leather, and the plurality of first negative pressure nozzles 2220 are respectively embedded in the suction plate 2210, the suction end of each first negative pressure nozzle 2220 is exposed to the suction surface 2212, and one end of each first negative pressure nozzle 2220 away from the suction end is respectively communicated with a gas source system; the discharging mechanism 300 includes a material taking frame 310, a supporting plate 320, and a plurality of second negative pressure nozzles 330; one end of the material taking frame 310 is connected to the telescopic turnover mechanism 100, the supporting plate 320 is installed at the other end of the material taking frame 310, the plurality of second negative pressure nozzles 330 are respectively fixedly installed on the supporting plate 320, the suction end of each second negative pressure nozzle 330 is used for abutting against and suctioning the leather plastic shell, and one end of each second negative pressure nozzle 330 away from the suction end is respectively communicated with the gas source system.

[0040] In the embodiment, the air source system can form negative pressure between the suction end of the plurality of first negative pressure nozzles 2220 and the leather to rapidly and reliably suction the leather on the suction surface 2212 of the suction plate 2210. Thus, in the mold opening stage, the telescopic turnover mechanism 100 drives the feeding mechanism 200 and the discharging mechanism 300 to move into the mold cavity, the air source system can synchronously drive the suction end of the plurality of second negative pressure nozzles 330 and the leather plastic shell to form negative pressure, so that the leather plastic shell is firmly suctioned on the plurality of second negative pressure nozzles 330 to realize the discharging action. Then, the suction surface 2212 of the suction plate 2210 is aligned with the mold cavity to put the leather into the mold cavity to realize the feeding action. The feeding and discharging device 10 for leather rear cover injection molding can realize automatic feeding and discharging action through the combination of the feeding mechanism 200 and the discharging mechanism 300, greatly reducing the work burden of the workers, effectively shortening the production cycle of the product, and replacing the traditional manual feeding and discharging mode, thereby avoiding the contact of the hands with the leather and the leather plastic shell, and effectively improving the yield of the product.

[0041] It should be noted that the telescopic turnover mechanism 100 can drive the feeding and discharging device 10 for leather rear cover injection molding to move into the mold cavity to sequentially perform the feeding and discharging action when the injection mold is opened, and the working principle of the injection molding machine manipulator and the telescopic turnover mechanism 100 both belong to the prior art, which will not be described in detail here.

[0042] As shown in Figure 1 and Figure 3 , in one of the embodiments, the feeding mechanism 200 further comprises a first telescopic driving member 230, the first telescopic driving member 230 is located between the base plate 210 and the suction plate 2210, and the first telescopic driving member 230 is used to drive the suction plate 2210 away from or close to the base plate 210.

[0043] It can be understood that, since the thickness of the leather is relatively thin, in the process of actually suctioning the leather by the suction plate 2210 and the first negative pressure nozzle 2220, the first telescopic driving member 230 can drive the suction plate 2210 to move towards the leather, and the suction surface 2212 can press the plane of the leather, so that the suction of the leather is more firm.

[0044] As shown in Figures 1 to 3 , in one of the embodiments, the feeding mechanism 200 further comprises a positioning assembly 240, the positioning assembly 240 comprises a plurality of coarse positioning columns 2410, one end of each of the coarse positioning columns 2410 is fixedly connected with the other face of the base plate 210, and the other end of each of the coarse positioning columns 2410 is used to align the corresponding positioning sleeve 4120 on the feeding jig 400.

[0045] It can be understood that before the leather is adsorbed by the adsorption plate 2210, the coarse positioning column 2410 is first accurately positioned with the positioning sleeve 4120 on the feeding jig 400, so as to ensure that the adsorption surface 2212 is aligned with the leather, thereby effectively improving the accuracy of adsorption of the adsorption surface 2212.

[0046] As shown in Figures 1 to 6 , in one of the embodiments, the positioning assembly 240 further comprises a plurality of fine positioning columns 2420, one end of each of the fine positioning columns 2420 is fixedly connected to the other face of the base plate 210, and the other end of each of the fine positioning columns 2420 is formed with a positioning portion 2422, the positioning portion 2422 is used to pass through the positioning hole in the periphery of the leather when the leather is adsorbed on the adsorption surface 2212; the adsorption plate 2210 is provided with a plurality of first through holes 2214, and the other end of each of the fine positioning columns 2420 passes through the corresponding first through hole 2214.

[0047] It can be understood that in the present embodiment, the length of the coarse positioning column 2410 is greater than the length of the fine positioning column 2420, so when the feeding mechanism 200 moves towards the leather, the coarse positioning column 2410 is first positioned with the positioning sleeve 4120 to ensure that the adsorption surface 2212 is preliminarily aligned with the leather; and then, when the adsorption surface 2212 abuts against the leather, the positioning portion 2422 is accurately passed through the positioning hole in the periphery of the leather, so as to effectively prevent the leather from being deviated or shaken during the adsorption process; in this way, when the telescopic turnover mechanism 100 drives the feeding mechanism 200 to move into the mold cavity for feeding, the precision of placing the leather by the adsorption plate 2210 into the mold cavity is effectively improved.

[0048] It should be noted that in the present embodiment, when the injection mold is opened, the leather plastic shell is attached to the rear mold cavity, so during the feeding of the leather, the leather is placed in the front mold cavity by the adsorption plate 2210.

[0049] As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , in one of the embodiments, the feeding mechanism 200 further comprises a plurality of ejecting pieces 250, one end of each of the ejecting pieces 250 is fixedly connected to the other face of the base plate 210; the adsorption plate 2210 is further provided with a plurality of second through holes 2216, and the other end of each of the ejecting pieces 250 passes through the corresponding second through hole 2216.

[0050] It can be understood that when the adsorption plate 2210 is placed after the leather is aligned and placed in the front mold cavity, the air source system drives the adsorption end of the first negative pressure suction nozzle 2220 to cancel the negative pressure; at this time, the first telescopic driving part 230 drives the adsorption plate 2210 to move close to the base plate 210, so that the other end of the ejection part 250 protrudes from the adsorption surface 2212 and abuts against the leather, thereby lifting the leather away from the adsorption surface 2212 and adhering to the front mold cavity, thereby realizing an automatic feeding mode, greatly reducing the work burden of the workers, and effectively shortening the production cycle of the product.

[0051] As shown in Figure 3 , in one of the embodiments, the feeding mechanism 200 further comprises a plurality of guide columns 260, one end of each of the plurality of guide columns 260 is fixedly connected to the side of the adsorption plate 2210 away from the adsorption surface 2212; a plurality of sliding sleeves 2110 are arranged on the base plate 210, and each sliding sleeve 2110 is in sliding connection with the other end of the corresponding guide column 260. In this way, the smoothness of the sliding process of the first telescopic driving part 230 driving the adsorption plate 2210 away from or close to the base plate 210 can be effectively ensured, thereby improving the feeding rate of the adsorption plate 2210 and effectively shortening the production cycle of the product.

[0052] As shown in Figure 1 and Figure 7 , in one of the embodiments, the material taking frame 310 comprises a turnover part 3110, a base 3120 and a second telescopic driving part 3130; the support plate 320 is connected with the turnover part 3110, the second telescopic driving part 3130 is built-in in the base 3120, the turnover part 3110 is movably connected with the telescopic driving end of the second telescopic driving part 3130, and the second telescopic driving part 3130 is used to drive the turnover part 3110 to rotate with the base 3120 to drive the support plate 320 to turn over. In this way, the leather plastic shell body adsorbed by the second negative pressure suction nozzle 330 is placed horizontally by turning over the support plate 320.

[0053] Specifically, the feeding mechanism 200 and the discharging mechanism 300 are turned over around the X axis (as shown in Figure 1 ) by the telescopic turnover mechanism 100 of the injection molding machine mechanical arm, so that the material taking frame 310 faces downward, at this time the feeding mechanism 200 is turned over to the side of the telescopic turnover mechanism 100, and then the turnover part 3110 is turned over relative to the base 3120 by the second telescopic driving part 3130 (as shown in the state of Figure 8 ), at this time the leather plastic shell body adsorbed from the rear mold cavity by the second negative pressure suction nozzle 330 is in a horizontal state, i.e. the leather plastic shell body is parallel to the horizontal plane at this time, so as to facilitate the placement of the discharged leather plastic shell body.

[0054] Please refer to Figures 9 to 10The application also provides a feeding and discharging device for leather rear cover injection molding, which comprises a feeding jig 400 and the feeding and discharging device 10 for leather rear cover injection molding described in any of the above embodiments, and the feeding and discharging device 10 for leather rear cover injection molding has a plurality of coarse positioning columns 2410; the feeding jig 400 comprises a transfer support 410, a third telescopic driving member 420 and a feeding plate 430; the top surface of the transfer support 410 is provided with a profiling placement area 4101 and a plurality of limiting columns 4110 distributed along the periphery of the profiling placement area 4101, each limiting column 4110 is used for penetrating a corresponding positioning hole in the periphery of the leather, the profiling placement area 4101 is used for placing the leather, the feeding plate 430 is embedded in the transfer support 410, and the feeding plate 430 is located below the profiling placement area 4101, and the telescopic driving end of the third telescopic driving member 420 is connected with the feeding plate 430.

[0055] It should be noted that in the embodiment, a plurality of positioning holes are formed in the periphery of the leather, and the limiting columns 4110 on the top surface of the transfer support 410 penetrate the positioning holes, so that the position accuracy of the leather placed on the profiling placement area 4101 is improved, and then the accuracy of the suction surface 2212 is ensured, and thus the accuracy of the suction plate 2210 placing the leather into the mold cavity is further improved, so that the production quality of the product is effectively ensured.

[0056] It can be understood that when the suction surface 2212 abuts against the leather in the profiling placement area 4101, the third telescopic driving member 420 synchronously drives the feeding plate 430 to be lifted towards the suction plate 2210, so that the extrusion force is formed between the feeding plate 430 and the suction surface 2212 of the suction plate 2210, and thus the leather has good flatness when being sucked.

[0057] It should be further noted that in the embodiment, the first telescopic driving member 230, the second telescopic driving member 3130 and the third telescopic driving member 420 are all telescopic cylinders, so that the first telescopic driving member 230, the second telescopic driving member 3130 and the third telescopic driving member 420 have good response rate, and the working efficiency of the feeding and discharging device 10 for leather rear cover injection molding is effectively improved.

In this way, when the suction plate 2210 moves towards the profiling placement area 4101, the suction surface 2212 and the leather can be well aligned; at the same time, the wear resistance when the two are aligned is also improved by the positioning sleeves 4120.

[0059] As shown in Figure 9 and Figure 10As shown, in one of the embodiments, the feeding and discharging device further comprises a workbench 500, and a first sliding mechanism 600, a second sliding mechanism 700, a first storage bin 800 and a second storage bin 900 which are respectively installed on the workbench 500; the first storage bin 800 and the second storage bin 900 are used for stacking the leather, the first sliding mechanism 600 is provided with a lifting transfer jig 610, the lifting transfer jig 610 is used for carrying the leather in the first storage bin 800 or the second storage bin 900 to the profiling placement area 4101, the transfer support 410 is installed on the second sliding mechanism 700, and the first sliding mechanism 600 and the second sliding mechanism 700 are arranged perpendicularly to each other.

[0060] In the embodiment, the feeding mechanism 200 adopts a multi-station design, that is, the feeding mechanism 200 is provided with a plurality of adsorption plates 2210 to simultaneously adsorb the leather for feeding, so that the efficiency of the leather feeding is effectively improved; correspondingly, the top surface of the transfer support 410 of the feeding jig 400 is also provided with a plurality of profiling placement areas 4101, so that the workers can stack the leather in the first storage bin 800 and the second storage bin 900, so that the lifting transfer jig 610 can automatically transfer the leather from the first storage bin 800 and the second storage bin 900 to the profiling placement area 4101, and the transfer support 410 is driven by the second sliding mechanism 700 to a predetermined position, so as to facilitate the feeding mechanism 200 to automatically adsorb the leather for feeding.

[0061] Compared with the prior art, the utility model has at least the following advantages:

[0062] The suction ends of the plurality of first negative pressure nozzles and the leather are synchronously driven by the air source system to form negative pressure between them, so that the leather is rapidly and reliably adsorbed on the adsorption surface of the adsorption plate; in this way, in the mold opening stage of the injection mold, the telescopic turnover mechanism drives the feeding mechanism and the discharging mechanism to move into the mold cavity, and the suction ends of the plurality of second negative pressure nozzles and the leather plastic shell are synchronously driven by the air source system to form negative pressure between them, so that the leather plastic shell is firmly adsorbed on the plurality of second negative pressure nozzles, to realize the discharging action; then the adsorption surface of the adsorption plate is aligned with the mold cavity to put the leather into the mold cavity, to realize the feeding action.
