DETAILED DESCRIPTION

[0033] The utility model is further described below in combination with the embodiments shown in the drawings.

[0034] The utility model discloses a notebook computer shell uses iron sheet automatic suction device, and the tray 4 is full of iron sheet and shifts to the place of feeding assembly, and the suction assembly absorbs the iron sheet and places on the positioning assembly, and the positioning assembly carries out secondary positioning to the iron sheet, avoids the iron sheet to put crooked, and finally the suction assembly absorbs the iron sheet after positioning and puts into the mold and forms.

[0035] As Figure 1 The utility model discloses a notebook computer shell uses iron sheet automatic suction device, and the tray 4 is full of iron sheet and shifts to the place of feeding assembly, and the suction assembly absorbs the iron sheet and places on the positioning assembly, and the positioning assembly carries out secondary positioning to the iron sheet, avoids the iron sheet to put crooked, and finally the suction assembly absorbs the iron sheet after positioning and puts into the mold and forms.

[0036] The feeding assembly includes feeding frame 1, positioning groove 2, first positioning column 3, tray 4, first positioning hole 5, clamping cylinder 6, first sliding rail 7, first sliding block 8, sliding plate 9, lifting cylinder 10, carrier plate 11, second positioning column 12, second positioning hole 13, angle plate 14, jacking cylinder 15, push plate 16, mounting frame 17, mounting groove 18 and gyro wheel 19, feeding frame 1 is fixed on the workshop ground, and is intervally set up, and positioning groove 2 is set up in the inside top of feeding frame 1, and carrier plate 11 receives the tray 4 full of iron sheet and shifts to positioning groove 2.

[0037] First positioning column 3 is fixed at the top of positioning groove 2, and first positioning hole 5 penetrates tray 4 and is matched with first positioning column 3, and carrier plate 11 shifts tray 4 full of iron sheet to positioning groove 2.When carrier plate 11 drops, tray 4 is placed in positioning groove 2, and at this time, the first positioning hole 5 on tray 4 is inserted on the first positioning column 3, so as to complete the positioning of tray 4, and avoid the tray 4 from shaking in the subsequent material taking, thereby affecting the material taking process.

[0038] As Figure 6 The first positioning column 3 and the first positioning hole 5 are diagonally positioned, and only two first positioning columns 3 are needed to realize the accurate positioning of the tray 4, and the cost is lower.

[0039] Clamping cylinder 6 is fixed on feeding frame 1, and after tray 4 shifts to positioning groove 2, clamping cylinder 6 acts to press on the top of tray 4, avoiding the upward deviation of tray 4. Clamping cylinder 6 selects ACKR / L25*90 type cylinder on the market, which can clamp tray 4, and avoid interference with the lifting movement of carrier plate 11 during material replacement.

[0040] A first slide rail 7 is screwed to the ground and positioned below the feeder rack 1. A first slider 8 is slidably mounted on the first slide rail 7, and a slide plate 9 is secured to the top of the first slider 8. A pneumatic cylinder drives the slide plate 9 along the first slide rail 7, enabling feeding and reloading (the cylinder is not shown). The coordinated arrangement of the first slide rail 7 and first slider 8 improves the stability of the slide plate 9's movement, thereby enhancing the accuracy of feeding and reloading.

[0041] A lifting cylinder 10 is fixed to the top of the slide 9. A carrier plate 11 is connected to the piston rod of the lifting cylinder 10, driving the lifting motion of the carrier plate 11. A second positioning post 12 is fixed to the top of the carrier plate 11. A second positioning hole 13 is provided at the bottom of the material tray 4 and engages with the second positioning post 12.

[0042] A mounting frame 17 is fixed to the ground via a profile and is located on one side of the feed frame 1. A mounting slot 18 is defined at the top of the mounting frame 17, and multiple rollers 19 are rotatably mounted within the slots 18. When a tray 4 is completely empty and needs to be replaced, the carrier plate 11 transfers the tray 4 to the rollers 19 and pushes it outward in the direction of rotation, preventing operators from reaching into the machine to retrieve the tray 4 and potentially causing safety accidents.

[0043] The roller 19 is made of rubber to avoid scratching the lower surface of the material tray 4 when pushing the material tray 4.

[0044] The angle plate 14 is fixed on the side of the carrier plate 11 away from the feeding rack 1, the lifting cylinder 15 is fixed on the angle plate 14, and the push plate 16 is fixed on the piston rod of the lifting cylinder 15. The push plate 16 is driven to move outward by the carrier plate 11, and then the push plate 16 pushes the empty material tray 4 outward along the rolling direction of the roller 19.

[0045] like Figure 6 As shown, the positioning assembly is fixed to one side of the feeding assembly. After the suction assembly sucks the iron piece on the material tray 4, it is easy to suck the iron piece crooked. Therefore, the positioning assembly is used to perform secondary positioning on the iron piece. The positioning assembly includes a positioning frame 20, a positioning plate 21, a pushing cylinder 22, a pushing plate 23 and a stopper 24. The positioning frame 20 is fixed on the workshop floor and is located on one side of the feeding frame 1.

[0046] A positioning plate 21 is fixed to the top of the positioning frame 20 and mates with the structure of the iron sheet. After the suction assembly absorbs the iron sheet from the material tray 4, it first places the iron sheet on the positioning plate 21. A stopper 24 is fixed to the top of the positioning frame 20 and abuts against the positioning plate 21, positioning one side of the iron sheet.

[0047] The pushing cylinders 22 are three in number and are fixed on the top of the positioning frame 20, and are distributed on the remaining three sides of the positioning plate 21, and the pushing plates 23 are connected with the pushing cylinders 22, and are driven by the pushing cylinders 22 to move inward, and finally the three pushing plates 23 and the baffle 39 position the iron sheet on the positioning plate 21, and then the suction assembly can suck the iron sheet positioned on the positioning plate 21.

[0048] As shown in Figure 7 Fig. 3 is a structural schematic view of the suction assembly, which comprises a suction frame 25, a guide sleeve 26, a guide column 27, a first connecting plate 28, a second connecting plate 29, a suction hole 30 and a probe 31. The suction frame 25 is connected with the mechanical arm, the guide sleeve 26 is embedded in the bottom of the suction frame 25, the guide column 27 penetrates through the guide sleeve 26, the first connecting plate 28 is fixed on the top of the guide column 27, and the second connecting plate 29 is fixed on the bottom of the guide column 27.

[0049] The suction block 40 is fixed on the bottom of the second connecting plate 29, the suction hole 30 penetrates through the second connecting plate 29 and is connected with the air channel of the suction block 40, and the air pipe joint connected with the vacuum pump is installed in the suction hole 30, so that the suction block 40 can suck the iron sheet on the tray 4.

[0050] The probe 31 is fixed on the bottom of the first connecting plate 28 and penetrates through the second connecting plate 29 and the suction block 40, and avoids the position of the air channel of the suction block 40. The probe 31 is used to detect the front and back surfaces of the iron sheet, because the operator is easy to put the iron sheet upside down when putting the iron sheet on the tray 4.

[0051] As shown in Figure 8 Fig. 4 is a schematic view when the iron sheet is correctly sucked, at this time the iron nail of the iron sheet faces downward, and the upper surface of the iron sheet is horizontal, when the suction block 40 sucks the iron sheet, the probe 31 contacts with the upper surface of the iron sheet, which indicates that the iron sheet is correctly placed. Figure 9 As shown in Fig. 5, if the iron sheet is upside down, the iron nail of the iron sheet faces upward, when the suction block 40 sucks the iron sheet, the iron nail will be resisted between the iron sheet and the suction block 40, which causes the probe 31 to fail to contact with the surface of the iron sheet, which indicates that the iron sheet is upside down, at this time the mechanical arm drives the suction frame 25 to move to the bunker, and the upside-down iron sheet is put into the bunker.

[0052] The spring is sleeved on the guide column 27 and is located between the guide sleeve 26 and the second connecting plate 29, in actual suction of the iron sheet, the suction block 40 first contacts with the iron sheet, the front and back surfaces of the iron sheet are detected by the probe 31, then the suction frame 25 is lowered by a certain distance, at this time the guide sleeve 26 is lowered to the compressed spring, under the reverse force of the spring, the suction block 40 is ensured to be in close contact with the iron sheet, and the suction is more firm.

[0053] The refilling assembly is arranged on the mounting frame 17 and is used for automatically replacing the tray 4 on the loading plate 11, and the refilling assembly comprises a refilling frame 32, a second sliding rail 33, a second sliding block 34, a refilling cylinder 35, a top plate 36, a refilling plate 37, a refilling groove 38 and a baffle 39. The refilling frame 32 is fixed on the workshop floor and arranged on the mounting frame 17, the second sliding rail 33 is fixed on the inner side of the refilling frame 32 by screw fastening, and the second sliding block 34 is slidingly arranged on the second sliding rail 33.

[0054] The refilling plate 37 is provided with two plates which are fixed on the second sliding block 34, the top plate 36 is fixed on the top of the refilling plate 37 and is driven to ascend and descend by the refilling cylinder 35 (a common lifting cylinder 10 can be selected for the refilling cylinder 35).

[0055] The refilling groove 38 is arranged on the inner side of the refilling plate 37 and is spaced apart, the tray 4 loaded with the iron sheet is inserted into the refilling groove 38, the height of the refilling groove 38 is greater than the thickness of the tray 4, and the loading plate 11 can be pulled out to the outermost tray 4, so that the tray 4 is prevented from being stuck.

[0056] The baffle 39 is fixed on the inner side of the refilling frame 32 and abuts against the side of the refilling plate 37 close to the feeding frame 1, the baffle 39 and the refilling plate 37 are only abutted against each other and are not fixed, otherwise the refilling plate 37 cannot be lowered to refill. When the operator inserts the tray 4 filled with the iron sheet into the refilling groove 38, the tray 4 can abut against the baffle 39, the tray 4 is limited by the baffle 39, the depths inserted by different operators are prevented from being inconsistent, and the second positioning column 12 of the loading plate 11 cannot be accurately inserted into the second positioning hole 13 at the bottom of the tray 4.

[0057] The working steps of the notebook computer shell iron sheet automatic suction device are as follows:

[0058] Firstly, the operator places the iron pieces in the iron piece groove of the tray 4, and then inserts the tray 4 full of iron pieces into the material changing groove 38 until the tray 4 abuts against the baffle 39; the material changing cylinder 35 drives the material changing plate 37 to descend, at the same time, the lifting cylinder 10 drives the carrier plate 11 to ascend until the second positioning column 12 of the carrier plate 11 is inserted into the second positioning hole 13 of the bottommost tray 4, the moving cylinder drives the sliding plate 9 to move outward to take out the bottommost tray 4 of the material changing groove 38 and move to the upper side of the feeding rack 1; the lifting cylinder 10 drives the carrier plate 11 to descend to place the tray 4 on the carrier plate 11 into the positioning groove 2 of the feeding rack 1, at this time, the first positioning hole 5 of the tray 4 is inserted into the first positioning column 3 of the positioning groove 2; then the suction assembly sucks the iron pieces on the tray 4 one by one to the positioning plate 21 for secondary positioning, and then transfers the secondary positioned iron pieces into the mold for forming; when the iron pieces on the tray 4 are taken out, the empty tray 4 is taken down and placed on the roller 19 through the cooperation of the moving cylinder and the lifting cylinder 10, the sliding plate 9 is moved to the lower side of the feeding rack 1 again by the moving cylinder, the push plate 16 is lifted to be flush with the empty carrier plate 11 by the jacking cylinder 15, and the empty tray 4 on the roller 19 is pushed to the outside by the push plate 16 when the sliding plate 9 is reset by the moving cylinder, and then the material changing plate 37 is driven to descend by the material changing cylinder 35, and the second last tray 4 is received by the carrier plate 11.
