Description

Technical Field

[0001] The invention relates to mechanical equipment for production, processing and storage in automated factories, in particular to a compact material unloading and lifting device for lightweight parts. Background Art

[0002] In certain industrial production fields, such as electronic parts manufacturing, small machinery assembly and other industries, the transfer and loading of lightweight standard parts are often involved. These lightweight standard parts usually have relatively uniform specifications and light weight, but in the production process, they need to be accurately transferred from the manual loading platform to the equipment operation platform for subsequent processing, testing or assembly processes.

[0003] When there is a height difference between the manual loading platform and the equipment operating platform, manual unloading will reduce the overall efficiency of the production line; and it is difficult for manual unloading to directly and stably place the materials at the exact position of the equipment operating platform, which is prone to placement deviations and affects the continuity of the production process.

[0004] Among the existing solutions, some companies use simple handheld handling aids, such as small pallets or simple lever aids. These tools have limited effect in solving the height difference problem and cannot automatically adjust the height to meet different operation requirements. During frequent use, these simple tools are prone to wear or inconvenience in operation, and cannot ensure stable and efficient loading operations.

[0005] On the other hand, although traditional large-scale material lifting equipment, such as heavy cranes and large hydraulic lifts, have strong lifting capabilities, they are too large, complex and expensive for lightweight materials. Their operation process is cumbersome and requires professional personnel to operate and maintain them. They are not suitable for frequent loading of lightweight materials, and their positioning accuracy cannot meet the requirements of accurate placement of lightweight standard parts.

[0048] The present invention will now be further described with reference to the accompanying drawings.

[0049] See also Figures 1 to 12 , Figures 1 to 12The present invention is a compact unloading and lifting device 100 for lightweight parts, which is used to lift lightweight components and standard parts to the operating platform of automated equipment after manual unloading. The embodiment mainly includes a frame 10, a housing 20, a universal supporting base 30, a rotating mechanism 40, a limit assembly 50 and a lifting mechanism 60.

[0050] like Figure 1 to Figure 2 As shown, the frame includes an upper frame 11 and a lower frame 12. In this embodiment, a shell 20 is further provided on the outer side of the frame and fixed below the upper frame 11. The universal supporting base 30 is provided above the upper frame 11, the rotating mechanism 40 is provided between the upper frame 11 and the shell 20, and the lifting mechanism 60 is provided between the lower frame 12 and the shell 20.

[0051] The lifting mechanism 60 is arranged on the lower frame 12 and drives the upper frame 11 to move up and down in the vertical direction; the upper end surface of the universal support base 30 is provided with a component box (not shown), and the lower end surface of the universal support base 30 is rotatably connected to the upper end of the upper frame 11 through a horizontal rotating shaft; the rotating mechanism 40 is arranged on the upper frame and drives the universal support base 30 to rotate relative to the upper frame by extending and retracting its output end up and down. Figures 3 to 6 As shown, the upper frame 11 includes a horizontally arranged upper frame top plate 111 and upper frame vertical plates 112 arranged vertically on both sides of the top plate. The two upper frame vertical plates 112 are respectively connected to the jacking mechanism and can move up and down under the drive of the jacking mechanism 60. In addition, a square hole 114 is also opened on the plate body of the upper frame top plate 111 for the connection piece of the rotating mechanism 40 and the universal supporting base 30 to pass through.

[0052] like Figures 3 to 10 As shown, the lower frame 12 includes a base 121 located at the bottom and arranged horizontally, and two vertical lower frame uprights 122 are arranged on the upper end surface of the base 121, and the upper frame 11 can be raised and lowered along the track 64 arranged vertically on the lower frame upright 122 through a slider 65. In addition, a guide rail base 123 is vertically installed on the side of the lower frame upright 122 close to the upper frame upright 112, and a guide shaft base 124 is vertically arranged on the base 121 with an opening facing upward, and the side surface is close to the lower frame upright 122.

[0053] Preferably, a light shielding sheet 113 corresponding to the photoelectric sensor of the lower frame 12 is provided on the upper frame vertical plate 112, and the light shielding sheet 113 is fixed to the lower side of the upper frame vertical plate 112. Correspondingly, the first limiter 125 is respectively provided on the upper and lower sides of the lower frame vertical plate 122, and is used to cooperate with the light shielding sheet 113 to limit the vertical lifting movement of the upper frame 11. Among them, the first limiter 125 is preferably a photoelectric sensor. Figures 3 to 10As shown, the universal supporting base 30 is arranged above the upper frame top plate 111, and includes a supporting base body 31, a first connecting member 32 and two positioning blocks 33. The supporting base body 31 is rotatably connected to the upper end surface of the upper frame top plate 111 through the first connecting member 32. In this embodiment, the universal supporting base 30 can rotate 30° around the first connecting member 32; the first connecting member 32 is preferably a shaft assembly. The board surface of the supporting base body 31 is provided with a mounting hole 34 for connecting with the fixed base of the component box.

[0054] Furthermore, two positioning blocks 33 are respectively installed on both sides below the supporting base body 31 to cooperate with the second limiting member 51 of the limiting assembly 50 to ensure that the supporting surface of the universal supporting base 30 is parallel to the ground when the material discharging is completed.

[0055] like Figures 3 to 10 As shown, the rotating mechanism 40 includes a first driving member 41, a second connecting member 42 and a third connecting member 43. The first driving member 41 is vertically arranged between the upper frame 11 and the housing 20 and is located below the upper frame top plate 111. The lower end of the first driving member 41 is rotatably connected to the upper frame vertical plate 112 through the second connecting member 42; the output end of the first driving member 41 passes upward through the square hole 114 of the upper frame top plate and is rotatably connected to the lower end surface of the universal supporting base 30 through the third connecting member 43. The output end of the first driving member 41 is extended and retracted, and the universal supporting base 30 is driven by the third connecting member 43 to rotate. Among them, the first driving member 41 is preferably an electric cylinder, and the second connecting member 42 and the third connecting member 43 are preferably connected by a hinge seat. The rotating mechanism 40 can rotate the universal supporting base 30 to a certain angle, and can tilt the universal supporting base 30 to the direction where the staff is when the material needs to be discharged, so that the material discharge operation is more convenient.

[0056] like Figure 11 to Figure 12 As shown, the lifting mechanism 60 includes a second driving member 61, a screw and screw nut assembly 62, a belt drive 63, a guide rail 64, a slider 65, a guide rod 66, and a guide rod connecting seat 67. The second driving member 61 is arranged on the upper side of the lower frame vertical plate 122 along the vertical direction. In the screw-screw nut assembly 62, the screw is vertically arranged in the guide rail base 123 on the lower frame 12, and its lower end is connected to the base 121 through a bearing, and the pulley at its upper end is connected to the pulley at the output end of the second driving member 61 through the transmission belt 63, and the screw nut is fixedly connected to the upper frame vertical plate 112. The output end of the second driving member 61 transmits the torque to the screw through the transmission belt 63, and then converts the rotational motion of the output end push rod into a linear lifting motion acting on the upper frame 11 through the screw nut.

[0057] Furthermore, two guide rails 64 are fixed on the guide rail base 123 of the lower frame 12 in the vertical direction, and a slider 65 connected to the upper frame vertical plate 112 is respectively installed on the two guide rails 64 to ensure the linear accuracy of the upper frame 11 when making longitudinal movement.

[0058] Furthermore, two guide rods 66 are respectively installed in the guide shaft base 124 on the lower frame 12, and their upper ends are fixed to the upper frame top plate 111 through the guide rod connecting seat 67. The guide rod 66 assists the guide rail 64 slider 65 mechanism to jointly ensure the linear accuracy of the vertical lifting movement of the upper frame 11 and enhance the overall strength of the device.

[0059] The lifting mechanism 60 uses a motor and a lead screw as main components, and a single slider mechanism is used on the guide rail 64 to ensure the linear accuracy during the lifting process, and the effective stroke of the lifting device is increased compared to the double slider mechanism. In addition, a combination of a guide rod 66 and a guide shaft base 124 is used, and the auxiliary guide rail 64 and the slider 65 jointly ensure the guiding accuracy and strengthen the overall rigidity of the lifting mechanism 60, so as to avoid damage to the single slider guide structure due to tilting or impact when the staff is carrying the device.

[0060] like Figures 7 to 10 As shown, the limiting assembly 50 includes two second limiting members 51 and a compensating member 52. The two second limiting members 51 are arranged on the upper end surface of the upper frame top plate 111, and their positions correspond to the two positioning blocks 33 of the universal supporting base 30. The two second limiting members 51 are preferably positioning bolts.

[0061] Furthermore, it also includes a compensating member 52, the contact at the top of the compensating member 52 is connected to its lower part through a compensating spring, and supports the lower end surface of the supporting base body. The compensating member 52 is arranged in the middle of the upper frame top plate 111. The limit assembly 50 keeps the universal supporting base 30 parallel to the ground when the material is discharged, and eliminates the gap between the connecting parts so that it will not move, ensuring the stability and repeated positioning accuracy of the universal supporting base 30 and the component box thereon during the movement.

[0062] See also Figure 1 and Figure 2 In use, when the first driving member 41 (electric cylinder) of this embodiment is working, the output end of the electric cylinder transmits the thrust to the universal supporting base 30 through the third connecting member 43, so that the universal supporting base 30 rotates 30° around the first connecting member 32 from the horizontal position, switching from the discharge completion position to the manual discharge position.

[0063] Correspondingly, when the staff completes the material discharge, the electric cylinder is reset, driving the universal support base 30 to return from the inclined manual material discharge position to the material discharge completion position. During this process, the lower end surface of the universal support 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 parts can be eliminated, and the stability of the universal support base 30 can be improved, so that it does not move.

[0064] Preferably, the height of the positioning nut of the second limiting member 51 can also be adjusted, so that under the joint action of the first connecting member 32 and the compensating member 52, the universal supporting base 30 always remains parallel to the ground, ensuring its stability and repeated positioning accuracy.

[0065] The above describes the implementation mode of the present invention in combination with the drawings and embodiments. The structure given in the embodiments does not constitute a limitation of the present invention. Those skilled in the art can make adjustments as needed. Various deformations or modifications within the scope of the attached claims are within the scope of protection.
