[0001] The invention relates to the technical field of material taking devices, and in particular to a suction cup type vacuum material taking device for lens protective plastic parts. Background Art

[0002] The suction cup vacuum picking device for lens protection plastic parts is specially designed for lens protection plastic parts. It uses the principle of combining suction cups with vacuum technology to achieve efficient, accurate and non-destructive material grabbing operations, and solves the problems of scratches, deformation and unstable picking and placing that may occur when traditional picking methods are used to handle such thin and fragile plastic parts.

[0003] A Chinese patent with the announcement number CN206068896U discloses a rotary suction cup material-retrieving device, which includes a rotating seat, on which a circumferentially arranged and radially telescopic telescopic arm is installed, a suction cup is fixed to the outer end of the telescopic arm, a slide rail is fixed around the axis of the rotating seat, the inner end of the telescopic arm is slidably matched with the slide rail, and the section of the slide rail facing the material bin is set as a cam section for driving the telescopic arm to extend and retract. The suction cup material-retrieving device of the present invention adopts a rotating seat to transfer materials, drives the telescopic arm to extend and retract through a cam slide rail, and uses the suction cup on the telescopic arm to suck materials from the material bin, and transfers the materials to the next station as the rotating seat rotates. The entire process only requires a cam slide rail to complete the suction and transfer of materials, and its drive can also be completed by only one motor without the need for a complex servo system.

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 10 As shown, a suction cup type vacuum material taking device for lens protective plastic parts of the present invention comprises: a frame 10 and a support plate 11, the support plate 11 is symmetrically arranged on the top of the frame 10, and also comprises: a slide rail support 20, two material storage tubes 40 and a control tube 50, the slide rail support 20 is arranged on the opposite side walls of the two support plates 11, and the front and rear sides of the slide rail support 20 are both provided with slide plates 23, and the initial positions of the two slide plates 23 are respectively located at the two ends of the length direction of the slide rail support 20, so that the two slide plates 23 can be moved along the slide rail support 20. The slide rail support 20 moves in the opposite direction of the length, and the two slide plates 23 are both provided with storage tubes 40 for lifting and lowering, and the two storage tubes 40 can load and unload materials alternately, and annular suction parts 42 are vertically spaced inside the storage tubes 40, and the outer wall of each annular suction part 42 is provided with a connecting tube 43, and the connecting tube 43 extends out of the outer wall of the storage tube 40, and the control tube 50 is provided on the outer wall of one side of the storage tube 40, and the control tube 50 is connected with multiple connecting tubes 43, and the control tube 50 is used to control the opening and closing of the connecting tubes 43 in sequence.

[0035] When the lens protection plastic parts are loaded, negative pressure suction gas enters into the interior of the control tube 50, and the control tube 50 controls the connecting tube 43 to open in turn from top to bottom, and the connecting tube 43 opens in turn to control the annular suction member 42 to suck the plastic parts in turn, and the annular suction member 42 also performs negative pressure suction from top to bottom, so that the lens protection plastic parts are stacked in intervals inside the storage tube 40. After the suction of the plastic parts inside the storage tube 40 is completed, the slide plate 23 drives the storage tube 40 to move along the length direction of the slide rail support 20. After moving to the unloading position, the annular suction member 42 is also closed in turn from bottom to top through the control tube 50, so that the plastic parts are unloaded in turn. By sucking multiple plastic parts at one time to pick up materials, the reciprocating stroke of picking up materials is reduced, and the two suction tubes are used to alternately pick up and unload materials, thereby realizing continuous loading and unloading, improving production efficiency, and reducing the economic cost of production.

[0036] like Figures 4 to 9 As shown, a first fixing plate 51 is provided on the top of the material storage tube 40, and the first fixing plate 51 is connected to the control tube 50, a second fixing plate 52 is provided on the outer wall of one side of the material storage tube 40, and the second fixing plate 52 is connected to the control tube 50, so that the control tube 50 is fixedly set on one side of the material storage tube 40, and a cylinder 41 is provided inside the material storage tube 40, and a group of suction holes 44 are circumferentially spaced apart on the outer circumferential surface of the cylinder 41, and a plurality of groups of suction holes 44 are axially spaced apart on the cylinder 41, and each group of suction holes 44 corresponds to an annular suction piece 42, and the annular suction piece 42 is used to connect a group of suction holes 44, and the connecting pipe 43 is connected to the annular suction piece 42 one by one, so that the connecting pipe 43 is used to connect the annular suction piece 42 and the control tube 50.

[0037] A suction pipe 55 is provided inside the control pipe 50, and the suction pipe 55 consists of four sections, which are respectively a first wide section, a first narrow section, a second wide section and a second narrow section from top to bottom, and the first wide section is connected to the uppermost connecting pipe 43, the first narrow section is connected to the connecting pipe 43 at the middle position, and the second narrow section is connected to the lowermost connecting pipe 43. A telescopic rod 60 is provided at the top of the suction pipe 55, and a connecting rod 61 is connected to the bottom end of the telescopic rod 60, and a first blocking block 62 and a second blocking block 63 are provided on the outer peripheral surface of the connecting rod 61, and the length of the second blocking block 63 is greater than that of the first blocking block 62, and in the initial state, the first blocking block 62 is located at the first narrow section position, and the second blocking block 63 is located at the second narrow section position. Fig. 9 As shown, a pipeline interface 56 is provided on the control tube 50 , and the gas sucked by negative pressure enters into the interior of the suction pipeline 55 through the pipeline interface 56 .

[0038] It should be noted that the bottom of the suction pipe 55 in the control pipe 50 is opened to avoid interference when the second blocking block 63 descends.

[0039] When the plurality of lens protection plastic parts are sucked and arranged in sequence into the material storage tube 40, the vacuum device is first connected to the pipeline interface 56 and negative pressure suction is performed, and the first blocking block 62 and the second blocking block 63 are located at the initial position. Fig. 9 As shown, at this time, only the uppermost connecting pipe 43 is in a connected state, and the gas sucked by negative pressure is sucked through the uppermost annular suction piece 42 and the uppermost group of suction holes 44, so that the plastic part moves upward from the bottom of the cylinder 41. When the plastic part moves axially along the cylinder 41 to the position of the uppermost group of suction holes 44, the sucked gas will suck the outer peripheral surface of the plastic part and stop the plastic part from moving.

[0040] When the first plastic part moves to the horizontal position of the uppermost connecting tube 43, the telescopic rod 60 pushes the connecting rod 61 downward, and the connecting rod 61 moves downward to drive the first blocking block 62 and the second blocking block 63 to move downward, so that the first blocking block 62 is separated from the connecting port of the connecting tube 43 at the middle position and then stops moving, and the second blocking block 63 is still in a blocking state for the lowermost connecting tube 43. Fig.10 As shown, at this time, the negative pressure suction gas can enter the group of suction holes 44 at the middle position through the connecting pipe 43 at the middle position, so that the plastic part moves along the axial direction of the cylinder 41 to the position of the group of suction holes 44 at the middle position.

[0041] After the second plastic part stops moving, the telescopic rod 60 also drives the connecting rod 61 to continue moving downward, so that the lowest connecting tube 43 is in an open state, and negative pressure suction is performed on the third plastic part. This is consistent with the above working principle and will not be repeated here, so that multiple plastic parts are stacked inside the storage tube 40 at intervals, so that the storage tube 40 can suction multiple plastic parts at one time, thereby reducing the reciprocating stroke and improving production efficiency. At the same time, the reduction in stroke leads to reduced wear and tear, while ensuring the service life of the device.

[0042] like Figures 4 to 5 As shown, a cylinder 30 is provided on the outer wall of one side of the slide plate 23, and a sliding frame 31 is provided at the output end of the cylinder 30. The cylinder 30 can push the sliding frame 31 to slide up and down. A connecting piece is provided at the bottom of the sliding frame 31, and the connecting piece is connected to the storage tube 40 so that the storage tube 40 can move up and down. Two slide bars 35 are provided on the outer wall of one side of the slide plate 23, and a sliding groove 36 is provided on the sliding frame 31, and the sliding groove 36 and the sliding bar 35 are slidably matched to improve the stability of the movement of the sliding frame 31. When taking or discharging materials, the cylinder 30 can push the sliding frame 31 to move, and the movement of the sliding frame 31 drives the storage tube 40 to move, thereby realizing taking and discharging materials.

[0043] A support block 32 is provided on the sliding frame 31, and the support block 32 is in the shape of a right-angled trapezoid, and a negative pressure suction device 33 is provided on the inclined surface of the support block 32, and the output end of the negative pressure suction device 33 is connected to a hose 34, and the other end of the hose 34 is connected to the pipeline interface 56. When negative pressure suction is performed on the plastic part, negative pressure suction is performed through the negative pressure suction device 33, so that the negative pressure suctioned gas enters the interior of the control tube 50 through the hose 34, and is opened and closed in sequence by the control tube 50, thereby realizing the loading and unloading of the plastic parts.

[0044] like Figures 1 to 3 As shown, the symmetrical sides of the slide rail support 20 are provided with electric slide rails 21, and the slide plate 23 is slidably matched with the electric slide rail 21, so that the slide plate 23 can slide back and forth along the length direction of the slide rail support 20, and the two slide plates 23 move in opposite directions, so that when the material storage tube 40 on one of the slide plates 23 is unloading, the material storage tube 40 on the other slide plate 23 is taking out the material, thereby realizing continuous material taking.

[0045] like Figure 2 As shown, a control module 24 is provided on the slide plate 23, and the control module 24 can adjust the size of the negative pressure suction device 33, and when unloading, the connecting tube 43 is closed from bottom to top in sequence through the control tube 50, so that the plastic parts at the bottom and the middle position fall in sequence, and the top plastic part requires the control module 24 to close the negative pressure suction device 33, so that the top plastic part falls axially along the cylinder 41.

[0046] like Figure 1 As shown, a support frame 12 is provided at the bottom of the frame 10, and the support frame 12 is used to stably support the frame 10 to ensure the stability of material taking and discharging.

[0047] It should be noted that since the two slides 23 are in inconsistent positions when taking or unloading materials, the plastic parts are transported to the material taking positions corresponding to the two slides 23 through two vibration plates, thereby ensuring the continuity of material taking, improving production efficiency and reducing equipment wear.
