[0048] The present application will be further described in combination with the drawings.

[0049] Referring to Figures 1 to 12 , Figures 1 to 12This illustration showcases an embodiment of the present invention: a compact material lifting device 100 for lightweight components, used to lift lightweight components and standard parts to the operating platform of automated equipment after manual material feeding. This embodiment mainly includes a frame 10, a housing 20, a universal support base 30, a rotating mechanism 40, a limiting component 50, and a lifting mechanism 60.

[0050] like Figures 1 to 2 As shown, the frame includes an upper frame 11 and a lower frame 12. In this embodiment, a housing 20 is also provided on the outside of the frame and fixed below the upper frame 11. A universal support base 30 is provided above the upper frame 11, a rotating mechanism 40 is located between the upper frame 11 and the housing 20, and a lifting mechanism 60 is located between the lower frame 12 and the housing 20.

[0051] The lifting mechanism 60 is mounted on the lower frame 12 and drives the upper frame 11 to move vertically up and down. The upper surface of the universal support base 30 has a component box (not shown), and the lower surface of the universal support base 30 is rotatably connected to the upper end of the upper frame 11 via a horizontal pivot. The rotating mechanism 40 is mounted on the upper frame and drives the universal support base 30 to rotate relative to the upper frame through the up and down extension of its output end. Figures 3 to 6 As shown, the upper frame 11 includes a horizontally arranged upper frame top plate 111 and two vertically arranged upper frame upright plates 112 on both sides of the top plate. The two upper frame upright plates 112 are respectively connected to the lifting mechanism and can move up and down under the drive of the lifting mechanism 60. In addition, the upper frame top plate 111 is also provided with square holes 114 for the connecting parts of the rotating mechanism 40 and the universal support base 30 to pass through.

[0052] like Figures 3 to 10 As shown, the lower frame 12 includes a horizontally positioned base 121 at the bottom. Two vertical lower frame support plates 122 are provided on the upper surface of the base 121. The upper frame 11 can be raised and lowered along a vertically positioned track 64 on the lower frame support plate 122 via a slider 65. Furthermore, a guide rail base 123 is vertically mounted on the lower frame support plate 122 near the upper frame support plate 112, and a guide shaft base 124 is vertically mounted on the base 121 with its opening facing upwards, its side close to the lower frame support plate 122.

[0053] Preferably, the upper frame upright plate 112 is provided with a light-shielding plate 113 corresponding to the photoelectric sensor of the lower frame 12, and the light-shielding plate 113 is fixed to the lower side of the upper frame upright plate 112. Correspondingly, first limiting members 125 are respectively provided on the upper and lower sides of the lower frame upright plate 122, and are used to limit the vertical lifting and lowering movement of the upper frame 11 in conjunction with the light-shielding plate 113. The first limiting member 125 is preferably a photoelectric sensor. Figures 3 to 10As shown, the universal support base 30 is arranged above the upper rack top plate 111, and includes a support base body 31, a first connecting piece 32, and two positioning blocks 33. The support base body 31 is rotationally connected to the upper end surface of the upper rack top plate 111 through the first connecting piece 32. In this embodiment, the universal support base 30 can rotate 30° around the first connecting piece 32. The first connecting piece 32 is preferably a shafting assembly. The plate surface of the support base body 31 is provided with a mounting hole 34 for connecting with the element box fixing base.

[0054] Further, the two positioning blocks 33 are respectively arranged on the two sides below the support base body 31, for cooperating with the second limiting piece 51 of the limiting assembly 50, so as to ensure that the support surface of the universal support base 30 is parallel to the ground when the discharging is completed.

[0055] As shown, Figures 3 to 10 The rotating mechanism 40 includes a first driving piece 41, a second connecting piece 42, and a third connecting piece 43. The first driving piece 41 is vertically arranged between the upper rack 11 and the shell 20, and is located below the upper rack top plate 111. The lower end of the first driving piece 41 is rotationally connected to the upper rack upright plate 112 through the second connecting piece 42. The output end of the first driving piece 41 passes through the square hole 114 of the upper rack top plate upwards, and is rotationally connected to the lower end surface of the universal support base 30 through the third connecting piece 43. The output end of the first driving piece 41 is driven by the third connecting piece 43 to rotate the universal support base 30. The first driving piece 41 is preferably an electric cylinder, and the second connecting piece 42 and the third connecting piece 43 are preferably hinged connections. The rotating mechanism 40 can rotate the universal support base 30 by a certain angle, and can tilt the universal support base 30 towards the direction of the staff when discharging is needed, so that the discharging operation is more convenient.

[0056] As shown, Figures 11 to 12 The jacking mechanism 60 includes a second driving piece 61, a lead screw and lead screw nut assembly 62, a belt transmission 63, a guide rail 64, a sliding block 65, a guide rod 66, and a guide rod connecting seat 67. The second driving piece 61 is arranged on the upper side of the lower rack upright plate 122 in the vertical direction. In the lead screw-lead screw nut assembly 62, the lead screw is vertically arranged in the guide rail base 123 of the lower rack 12, and the lower end thereof is connected to the base 121 through a bearing, and the upper end thereof is transmissionally connected to the pulley of the output end of the second driving piece 61 through the transmission belt 63. The lead screw nut is fixedly connected to the upper rack upright plate 112. The output end of the second driving piece 61 transmits the torque to the lead screw through the transmission belt 63, and converts the rotary motion of the output end push rod into the linear lifting motion acting on the upper rack 11 through the lead screw nut.

[0057] Further, two guide rails 64 are fixed on the guide rail base 123 of the lower frame 12 in the vertical direction, and a sliding block 65 connected with the vertical plate 112 of the upper frame 11 is respectively arranged on the two guide rails 64, so as to ensure the straightness of the upper frame 11 in the longitudinal movement.

[0058] Further, two guide rods 66 are respectively arranged in the guide rod base 124 of the lower frame 12, and the upper ends of the two guide rods 66 are fixed on the top plate 111 of the upper frame 11 through the guide rod connecting seat 67. The guide rods 66 assist the sliding block 65 mechanism of the guide rail 64, so as to ensure the straightness of the vertical lifting movement of the upper frame 11 and strengthen the overall strength of the device.

[0059] The jacking mechanism 60 adopts a motor and a lead screw as main components, and the single sliding block mechanism arranged on the guide rail 64 ensures the straightness in the jacking process. Compared with the double sliding block mechanism, the single sliding block mechanism also increases the effective stroke of the jacking device. In addition, the combination of the guide rod 66 and the guide rod base 124 assists the guide rail 64 and the sliding block 65 to ensure the guide precision and strengthen the overall rigidity of the jacking mechanism 60, so as to avoid the damage of the single sliding block guide rail structure caused by the inclination or impact of the staff during the carrying of the device.

[0060] As shown in Figures 7 to 10 , the limiting assembly 50 comprises two second limiting members 51 and a compensation member 52. The two second limiting members 51 are arranged on the upper end surface of the top plate 111 of the upper frame 11 and correspond to the two positioning blocks 33 of the universal support base 30. Preferably, the two second limiting members 51 are positioning bolts.

[0061] Further, the compensation member 52 is arranged in the middle of the top plate 111 of the upper frame 11. The contact at the top end of the compensation member 52 is connected with the lower part thereof through a compensation spring and abuts against the lower end surface of the support base body. The limiting assembly 50 makes the universal support base 30 parallel to the ground in the discharging completion position and eliminates the gap between the connecting members, so that the universal support base 30 and the element box thereon will not move, thereby ensuring the stability and the repeated positioning precision of the universal support base 30 and the element box thereon in the movement process.

[0062] Referring to Figure 1 and Figure 2 , in use, when the first driving member 41 (electric cylinder) works, the output end of the electric cylinder transmits the thrust to the universal support base 30 through the third connecting member 43, so that the universal support base 30 rotates 30° around the first connecting member 32 from the horizontal position to the manual discharging position.

[0063] Correspondingly, when the worker finishes the material placing, the electric cylinder resets, and drives the universal supporting base 30 to restore from the inclined manual material placing position to the material placing completion position. In this process, the lower end surface of the universal supporting base 30 contacts the contact of the compensation member 52 and compresses the compensation member spring. Under the action of the compensation member 52, the gap between the connecting members can be eliminated, the stability of the universal supporting base 30 is improved, and the universal supporting base 30 does not move.

[0064] As preferred, the height of the second limiting member 51 positioning nut can also be adjusted, under the joint action of the first connecting member 32 and the compensation member 52, so that the universal supporting base 30 always keeps parallel to the ground, and the stability and the repeated positioning accuracy are guaranteed.

[0065] The embodiments of the present application are described above in combination with the drawings and the embodiments, and the structure given by the embodiments does not constitute a limitation to the present application, and the skilled in the art can make adjustments according to the needs, and various deformations or modifications within the scope of the appended claims are within the protection scope.
