TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece lifting, in particular to a workpiece lifting and turning device. BACKGROUND

[0002] In modern industrial production, in order to complete product processing, the production line operation often encounters the need to lift the workpiece to a certain station and then turn a certain angle for transportation. The common mechanical equipment is to first lift the workpiece to the required height and then turn a certain angle, and then a workpiece lifting and turning device is needed to realize the lifting and turning operation of the workpiece.

[0003] For example, the Chinese invention patent with application number 201710487784.9 discloses a workpiece lifting and turning device, which comprises a bottom plate, a mounting table, a lead screw, a pinion, a driven gear, a lifting arm, a clamping jaw, an incomplete tooth large gear, an incomplete tooth driving gear, and a motor. The large gear is engaged with the pinion, the driving gear is engaged with the driven gear, and the driving gear is connected with the motor. An arc-shaped internal gear is connected to the outside of the large gear. A first transmission device and a second transmission device are arranged on the bottom plate. The differential rotation between the gears is realized by the motor drive, so that the lifting arm performs lifting and turning motion. The structure design is reasonable and convenient to use. The cooperation of the power output and the incomplete gear realizes the lifting and turning motion of the workpiece. The power output realizes the working and resetting of the device at the same time, which saves the circuit control process. The entire device has high automation degree and safe and stable operation.

[0004] In the prior art including the above-mentioned patent, it is impossible to continuously and efficiently lift and turn the light workpiece (such as light plastic parts). After lifting and turning the previous workpiece, the transport clamping jaw needs to be reset before lifting and turning the next workpiece. There is a long waiting gap in between. The lifting and turning steps of the workpiece are complicated and the stroke is long, which is not conducive to the continuous and efficient lifting and turning transportation of the workpiece. There are certain deficiencies and need to be improved.

[0005] Therefore, it is necessary to provide a workpiece lifting and turning device to solve the above technical problems. SUMMARY

[0006] The purpose of the present application is to provide a workpiece lifting and turning device to solve the problem that the prior art cannot continuously and efficiently lift and turn the light workpiece (such as light plastic parts). After lifting and turning the previous workpiece, the transport clamping jaw needs to be reset before lifting and turning the next workpiece. There is a long waiting gap in between. The lifting and turning steps of the workpiece are complicated and the stroke is long, which is not conducive to the continuous and efficient lifting and turning transportation of the workpiece.

[0007] To achieve the above object, the present application is implemented by the following technical solutions: A workpiece lifting and turning device, comprising conveyor one and conveyor two arranged vertically to each other, a controller is arranged on the conveyor one, a Z-shaped bearing frame is fixedly installed between the top of the conveyor one and the conveyor two through a support frame, a belt drive mechanism is arranged inside the Z-shaped bearing frame, the Z-shaped bearing frame is composed of a horizontal piece taking section, a vertical lifting section and a horizontal piece placing section, a plurality of moving frames are equidistantly arranged on the belt drive mechanism, a reset mechanism is arranged on one side of the moving frame, a lateral support is arranged on the side of the reset mechanism away from the Z-shaped bearing frame, two sets of workpiece clamping mechanisms are symmetrically arranged on the lateral support, a proximity switch (not shown in the figure) is arranged on one end of the conveyor one close to the Z-shaped bearing frame, the conveyor one and the proximity switch are electrically connected with the controller, for monitoring whether there is a workpiece to be transferred at the end of the conveyor one close to the Z-shaped bearing frame (i.e. directly below the Z-shaped bearing frame---workpiece taking position), when the workpiece taking position has a workpiece to be transferred, the proximity switch receives a signal and turns off the conveyor one through the controller to avoid excessive conveying and falling, and it is convenient to accurately convey the workpiece to be transferred to the workpiece taking position, and after the workpiece clamping mechanism clamps and transfers the workpiece, the proximity switch cannot receive a signal, at this time, the controller starts the conveyor one to convey the workpieces on the conveyor one to be transferred in a neat and spaced manner, so as to realize the conveying of the workpieces to be lifted and turned to the workpiece taking position in turn.

The workpiece is moved by the movement of the moving frame. When the passive incomplete gear on the moving frame passes through the driving rack, the passive incomplete gear rotates 180 degrees. In the process of rotating 90 degrees, the guide rod in the workpiece clamping mechanism passes through the vortex trigger guide bar, so that the workpiece clamping mechanism drives the workpiece to rotate 90 degrees and releases the clamping of the workpiece. The lifting and turning operation of the workpiece is completed, and then the workpiece clamping mechanism is rotated by 90 degrees to move to both sides of the workpiece, so that the conveyor two can transport the workpiece without being hindered by the workpiece clamping mechanism.

[0037] The two sides of moving frame 5 are fixedly connected with arc-shaped trigger guide bar 9, the arc-shaped trigger guide bar 9 is composed of vortex trigger arc-shaped bar 9001 and maintenance arc-shaped bar 9002, the vortex trigger arc-shaped bar 9001 is an arc-shaped bar with increasing radius, and the maintenance arc-shaped bar 9002 is an arc-shaped bar with equal radius, the support frame 15 is fixedly connected with inclined trigger guide bar 10 on both sides of the horizontal pick-up section 3001, and the two inclined trigger guide bars 10 are symmetrically arranged in the shape of "eight";

[0038] In actual application, through the setting of inclined trigger guide bar 10, in the process that workpiece clamping mechanism 8 enters horizontal pick-up section 3001, inclined trigger guide bar 10 can automatically open the clamping, to facilitate subsequent clamping and fixing of workpiece to be lifted and turned at pick-up station, when workpiece clamping mechanism 8 moves away from inclined trigger guide bar 10, the limit on workpiece clamping mechanism 8 is released, workpiece clamping mechanism 8 is reset to automatically clamp workpiece, with high automation degree;

[0039] The reset mechanism 6 is provided with a passive incomplete gear 11, the bottom of the horizontal placing piece section 3003 and above the conveyor two 2 is fixedly connected with a driving rack 12, the passive incomplete gear 11 is moved to the position opposite to the driving rack 12, and the two are in meshing relationship, so that the passive incomplete gear 11 can also rotate while moving, so as to turn the workpiece;

[0040] In actual application, the setting of the belt driving mechanism 4 can drive multiple moving frames 5 to move circularly along the outside of the Z-shaped bearing frame 3, and then the workpiece is lifted and turned by the workpiece clamping mechanism 8 on the moving frame 5. When the moving frame 5 moves to the relative position, the workpiece clamping mechanism 8 on the moving frame 5 is guided by the inclined trigger guide strip 10, so that the workpiece clamping mechanism 8 is in an open state, and then the workpiece clamping mechanism 8 is separated from the inclined trigger guide strip 10, the workpiece is clamped and fixed at the material taking station, and the workpiece is moved and lifted by the movement of the moving frame 5. When the passive incomplete gear 11 on the moving frame 5 passes through the driving rack 12, the passive incomplete gear 11 rotates 180 degrees, in the process of rotating 90 degrees, the guide rod 8002 in the workpiece clamping mechanism 8 passes through the vortex trigger guide strip, so that the workpiece clamping mechanism 8 drives the workpiece to rotate 90 degrees, and the workpiece is released, the lifting and turning operation of the workpiece is completed, and then the workpiece clamping mechanism 8 is moved to the two sides of the workpiece by rotating 90 degrees, so that the conveyor two 2 can transport the workpiece without being hindered by the workpiece clamping mechanism 8.

[0041] Three groups of sliding grooves 13 are formed in the Z-shaped bearing frame 3, and a limiting assembly is arranged on the inner wall of each moving frame 5 and corresponds to the position of the three groups of sliding grooves 13; the limiting assembly comprises three limiting rollers 14, the three limiting rollers 14 are rotatably connected with the inner wall of the moving frame 5, and the outer surface of the limiting roller 14 abuts with the inner wall of the sliding groove 13, one of the limiting rollers 14 is horizontally arranged, and the other two limiting rollers 14 are vertically arranged, and the two vertically arranged limiting rollers 14 are symmetrically arranged above and below the horizontally arranged limiting roller 14.

[0042] Through the cooperation of the sliding groove 13 and the limiting assembly, the moving frame 5 in the moving process can be limited, and the stability of the moving frame 5 is improved.

[0043] The reset mechanism 6 comprises a rotating shaft 6001 rotatably installed on the moving frame 5, one end of the rotating shaft 6001 is fixedly connected with a fixed disc 6002, the fixed disc 6002 and the moving frame 5 are fixedly connected with a reset torsion spring 6003, and the horizontal support 7 is fixedly connected with the fixed disc 6002.

[0044] The passive incomplete gear 11 is fixedly installed at the end of the rotating shaft 6001 away from the fixed disc 6002, and the range of the teeth on the passive incomplete gear 11 is 180 degrees, and the passive incomplete gear 11 at the corresponding position of the driving rack 12 is in meshing relationship.

[0045] The workpiece clamping mechanism 8 comprises a sliding block 8001 slidingly installed on the transverse support 7, a guide rod 8002 is rotatably connected to the top of the sliding block 8001, a clamping plate 8003 is fixedly connected to the bottom of the sliding block 8001, an extrusion spring 8004 is fixedly connected between the sliding block 8001 and the transverse support 7, and a rubber non-slip pad 8005 is fixedly connected to one side of the clamping plate 8003. The setting of the rubber non-slip pad 8005 can increase the friction force of the contact surface between the clamping plate 8003 and the clamped workpiece, thereby improving the effect of clamping and fixing the workpiece, and improving the stability in the subsequent workpiece conveying process.

[0046] Working principle: when the light workpiece (for example, light plastic part, referred to as: workpiece) needs to be lifted, turned and conveyed, the workers first place the workpieces to be conveyed on the conveying belt of the conveyor one 1 in equal intervals, then drive the workpieces placed on the top to move towards the side close to the Z-shaped bearing frame 3 through the movement of the conveyor one 1, until the workpieces move to the position directly below the Z-shaped bearing frame 3 (i.e. the taking material station), at the same time, the proximity switch monitors whether there is a workpiece to be transferred at the end of the conveyor one 1 close to the Z-shaped bearing frame 3 (i.e. the position directly below the Z-shaped bearing frame 3---the taking material station), when the taking material station has a workpiece to be transferred, the proximity switch receives a signal and closes the conveyor one 1 through the controller, to avoid excessive conveying and falling, and facilitate accurate conveying of the workpiece to be transferred to the taking material station, and after the workpiece clamping mechanism 8 clamps and transfers the workpiece, the proximity switch cannot receive a signal, at this time, the controller starts the conveyor one 1 to convey the workpieces placed on the conveyor one 1 in equal intervals to be transferred, so as to realize the conveying of the workpieces to be lifted and turned to the taking material station in turn.

[0047] Meanwhile, the belt driving mechanism 4 drives the plurality of moving frames 5 to move along the sliding groove 13 on the Z-shaped carrier 3. When the moving frame 5 moves at the lower side of the horizontal taking section 3001, the guide rod 8002 in the workpiece clamping mechanism 8 contacts the inclined trigger guide strip 10, the inclined trigger guide strip 10 guides the guide rod 8002 to move away from the Z-shaped carrier 3, and drives the sliding block 8001 and the clamping plate 8003 to move synchronously. The movement of the sliding block 8001 extrudes the compression spring 8004 to be in a compressed state and stores energy. The two clamping plates 8003 move away from each other to be opened, so as to facilitate subsequent clamping of the workpiece to be transferred. When the guide rod 8002 continues to move and is separated from the inclined trigger guide strip 10, the sliding block 8001 and the clamping plate 8003 are driven to move by the elastic force of the compression spring 8004, so that the two clamping plates 8003 are clamped on both sides of the workpiece. The setting of the rubber non-slip pad 8005 can improve the friction between the contact surface of the clamping plate 8003 and the workpiece, improve the clamping and fixing effect of the workpiece, and improve the stability in the subsequent workpiece conveying process. After the workpiece clamping mechanism 8 clamps and fixes the workpiece, since the belt driving mechanism 4 is in a continuous operation state, the moving frame 5, the workpiece clamping mechanism 8 and the workpiece clamped and fixed on the workpiece clamping mechanism 8 are driven to move along the horizontal taking section 3001, and then enter the vertical lifting section 3002 to be lifted upward. Finally, the moving frame 5 enters the horizontal placing section 3003. During the movement of the moving frame 5 in the horizontal placing section 3003, the driven incomplete gear 11 moves synchronously. When the driven incomplete gear 11 moves to a position opposite to the driving rack 12, the driven incomplete gear 11 and the driving rack 12 are in meshing state. Under the action of the driving rack 12, the driven incomplete gear 11 moves and rotates. The rotation of the driven incomplete gear 11 drives the horizontal support 7 and the fixed disc 6002 to rotate. The rotation of the fixed disc 6002 causes the reset torsional spring 6003 to deform and store energy. The rotation of the horizontal support 7 drives the workpiece clamping mechanism 8 and the workpiece clamped and fixed on the workpiece clamping mechanism 8 to rotate. When the guide rod 8002 on the workpiece clamping mechanism 8 rotates to abut against the vortex trigger guide strip, the vortex trigger guide strip guides the guide rod 8002 to move away from the rotating shaft 6001, thereby driving the two clamping plates 8003 to move away from each other, so as to release the clamping of the workpiece. At this time, the clamping plates 8003 are located on the front and rear sides of the workpiece. The clamping plate 8003 located on the rear side of the workpiece hinders the conveying of the workpiece. At this time, the driven incomplete gear 11 continues to move, and the guide rod 8002 moves to the maintenance arc-shaped strip 9002, so that the workpiece clamping mechanism 8 maintains the state of releasing the clamping of the workpiece. The rotation of the driven incomplete gear 11 drives the workpiece clamping mechanism 8 to continue to rotate by 90 degrees, that is, the clamping plate 8003 rotates to the two sides of the workpiece, so as to avoid the clamping plate 8003 from hindering the workpiece, so as to facilitate the normal conveying of the workpiece by the conveyor two 2.

[0048] Through the circulation movement of the plurality of moving frames 5 and the workpiece clamping mechanisms 8 on the moving frames 5 and the like, the workpieces on the conveyor one 1 to be lifted and diverted can be sequentially lifted and diverted to the conveyor two 2, the continuity and efficiency of the workpiece lifting and diverting device are optimized, the workpieces can be efficiently and continuously lifted and diverted, and the problems in the prior art that the light workpieces cannot be continuously and efficiently lifted and diverted, the transport clamping jaws need to be reset after the lifting and diverting of the previous workpiece, the next workpiece cannot be lifted and diverted, there is a long waiting interval, the lifting and diverting steps of the workpieces are complicated, and the stroke is long, which is not conducive to the continuity and efficient lifting and diverting of the workpieces.

[0049] Embodiment two: this embodiment is basically the same as the previous embodiment, the difference is that the belt driving mechanism 4 includes two belt pulleys 4001, the two belt pulleys 4001 are respectively rotatably installed at the opposite ends inside the horizontal workpiece taking section 3001 and the horizontal workpiece placing section 3003, a driving belt 4002 is drivingly connected between the two belt pulleys 4001, and the moving frame 5 is fixedly installed on one side of the driving belt 4002, so that the driving belt 4002 drives the moving frame 5 to move synchronously during the movement of the driving belt 4002, and an external driving motor (not shown in the figure) drives at least one belt pulley 4001 to rotate, so that the belt driving mechanism 4 operates.

[0050] A plurality of guide wheels 4003 are rotatably installed inside the vertical lifting section 3002, the guide wheels 4003 bend and guide the driving belt 4002 into a Z shape and adapt to the shape of the Z-shaped carrier 3.

[0051] The external driving motor drives the belt pulley 4001 to rotate, and then drives the driving belt 4002 to move, and drives the plurality of moving frames 5 to move synchronously along the sliding groove 13 on the Z-shaped carrier 3.
