[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 7 As shown, this embodiment provides a lifting and feeding machine, including a turntable 10, stacking groups 20, and a lifting assembly 30. The turntable 10 is rotatably mounted. Several stacking groups 20 are arranged on the turntable 10, each with a storage space suitable for placing the workpiece 80 to be processed. The turntable 10 has several perforated groups 12. These perforated groups 12 are connected to the stacking groups 20. The perforated group 12 is connected to the storage space. The lifting component 30 is located on the side of the turntable 10 away from the stacking group 20. The lifting component 30 includes a lifting part 31 and a reference pointer 32. The lifting part 31 is adapted to pass through a perforated group 12 and extend into the storage space. An angle scale line 11 is provided on the turntable 10. The angle scale line 11 has a zero position scale. Before the lifting feeder is turned on, the reference pointer 32 is aligned with the zero position scale.

[0026] Before starting the lifting feeder of this embodiment, the reference pointer 32 is aligned with the zero mark on the turntable 10 to ensure that when the turntable 10 rotates to the stacking group 20 of each station, the lifting part 31 can smoothly pass through the perforation group 12 and enter the storage space to feed the workpiece 80 upwards, thereby solving the increasingly common jamming problem. The reference pointer 32 can determine the azimuth angle of each stacking group 20. The turntable 10 and the lifting component 30 realize the rotational feeding of the workpiece 80, realizing continuous feeding production after one feeding. By setting up several stacking groups 20, the filling frequency is reduced.

[0027] It should be noted that due to the movement of the turntable 10, the rotation accuracy of the turntable 10 may deviate. In this case, friction will occur between the lifting part 31 and the perforation 121, and the frictional wear of the lifting part 31 will also increase. In this embodiment, before starting the lifting feeder, the zero mark of the turntable 10 is adjusted to be aligned with the reference pointer 32 so as to ensure that the lifting part 31 can smoothly enter the storage space for feeding and reduce the frictional wear of the lifting part 31.

[0028] Specifically, the stacking group 20 is detachably connected to the turntable 10 to facilitate quick assembly and disassembly of the stacking group 20.

[0029] Specifically, in this embodiment, six stacking groups 20 are provided, and six perforation groups 12 are correspondingly provided. The six stacking groups 20 are evenly and spaced apart along the circumference of the turntable 10; for example... Figure 2 and Figure 3 As shown, the turntable 10 is provided with a positioning groove 13 to facilitate the quick positioning and installation of the stacking group 20; the indicator part of the reference pointer 32 is set close to the outer periphery of the turntable 10 so that the reference pointer 32 can be aligned with the angle scale line 11 for inspection; in this embodiment, the workpiece 80 to be processed is a metal sheet.

[0030] It should be noted that those skilled in the art can adjust the number of stack groups 20 according to actual needs.

[0031] It should be noted that in other alternative implementations, multiple stack groups can also be set at other preset intervals.

[0032] Furthermore, each code stack group 20 corresponds to an angle scale, with one code stack group 20 set to correspond to the zero-position scale.

[0033] It is understandable that each group of code stacks 20 corresponds to an angle scale, so as to use the reference pointer 32 to determine the azimuth angle of each group of code stacks 20, and also to determine whether the rotation of the turntable 10 has deviated at any position of the code stacks 20.

[0034] Understandably, the six stacking groups 20 are evenly and spaced along the circumference of the turntable 10, which facilitates the adjustment and control of the rotation of the turntable 10.

[0035] It should be noted that those skilled in the art can also adjust the setting position of the stack group 20 according to actual needs.

[0036] Specifically, such as Figure 2 As shown, at this time, the lifting assembly 30 is in the loading state, and the lifting part 31 passes through the perforated assembly 12 and extends into the storage space, lifting the metal sheet upwards so that the side-mounted universal robotic arm 90 can grasp the metal sheet; as Figure 3 As shown, at this time, all the metal sheets in a stacking group 20 have been fed, the lifting part 31 descends and is retracted by the perforation group 12. At this time, the turntable 10 can be rotated to rotate the next stacking group 20 to the working position of the lifting component 30 so as to facilitate continuous feeding.

[0037] It should be noted that by cooperating with the lifting component 30 and the turntable 10, continuous feeding production can be achieved after one loading of metal sheets.

[0038] like Figure 1 As shown, in this embodiment, the stacking group 20 includes at least one stacking slot 21, which is connected to the turntable 10. The perforation group 12 includes at least one perforation 121, which is correspondingly arranged with the stacking slot 21. Figure 6 As shown, the lifting part 31 includes at least one lifting block 311, and the lifting block 311 is arranged in a one-to-one correspondence with the stacking slot 21.

[0039] For details, please refer to Figure 1 Each stack group 20 includes two stack slots 21, which are flush and spaced apart; please refer to Figure 2 and Figure 3 Each perforation group 12 includes two perforations 121; see also Figure 6 The lifting section 31 includes two lifting blocks 311.

[0040] Furthermore, the spacing between the two stacking slots 21 is consistent with the spacing between the metal sheet insertions, so that the metal sheet can be processed directly after loading.

[0041] It should be noted that those skilled in the art can adjust the specific number of stacking slots 21 in a stacking group 20 according to actual needs, and correspondingly adjust the number of perforations 121 in a perforation group 12 and the number of lifting blocks 311 in the lifting part 31.

[0042] like Figure 4 and Figure 5As shown, in this embodiment, each stacking slot 21 includes a base 211 and at least two limiting posts 212. The base 211 is connected to the turntable 10. A through hole 214 is provided on the base 211, and the through hole 214 is connected to the through hole 121. Any two adjacent limiting posts 212 are spaced apart on the base 211. At least two limiting posts 212 and the base 211 enclose a storage space. A positioning angle 213 is formed on the side of the limiting post 212 near the storage space. The shapes of at least two positioning angles 213 of a stacking slot 21 are different.

[0043] Specifically, in this embodiment, each stacking slot 21 includes a base 211 and four limiting posts 212, with any two adjacent limiting posts 212 spaced apart on the base 211.

[0044] For further details, please refer to Figure 5 The positioning angles 213 of two of the limiting posts 212 are right angles, while the positioning angles 213 of the other two limiting posts 212 are rounded.

[0045] It should be noted that in other alternative embodiments, multiple positioning angles 213 of different angles can be set by the shape of the metal sheet.

[0046] Specifically, in this embodiment, the metal sheet in the storage space is a metal sheet without positioning holes.

[0047] It should be noted that in related technologies, three positioning holes are often opened on the metal sheet, and the three-point positioning method is used to ensure the feeding angle of the positioning metal sheet. However, this will damage the structural strength of the metal sheet. In this embodiment, by using at least two positioning angles 213 with different shapes, the correct installation of the metal sheet can be determined, and the metal sheet can be avoided from being fed and processed at the wrong angle.

[0048] It should be noted that the two adjacent limiting posts 212 are spaced apart to form a piece-grabbing groove between the two adjacent limiting posts 212, so that the gripping structure of the side-mounted universal robotic arm 90 can be embedded in the piece-grabbing groove to grip the metal piece.

[0049] Specifically, in this embodiment, the base 211 is detachably connected to the turntable 10 via pressure plate screws.

[0050] like Figure 6 As shown, the lifting assembly 30 also includes a guide rail structure 33, a slider 34, and a servo motor 35. The slider 34 is slidably mounted on the guide rail structure 33 and is connected to the servo motor 35 for transmission. The lifting part 31 is mounted on the slider 34, and the reference pointer 32 is mounted on the guide rail structure 33.

[0051] Specifically, the slider 34 is sleeved on the lead screw, which is connected to the output end of the servo motor 35. The servo motor 35 directly drives the lead screw to rotate forward or backward, thereby driving the lifting part 31 to rise or fall.

[0052] It is worth noting that the lifting block 311 is raised or lowered by the servo motor 35 to achieve the loading of the workpiece 80.

[0053] like Figure 1 and Figure 7 As shown, the lifting and feeding machine also includes a rotary motor 40 and a cam divider 50. The turntable 10 is connected to the cam divider 50 in a driving connection, and the rotary motor 40 is connected to the cam divider 50 in a driving connection.

[0054] It is worth noting that the cam divider 50 provides a stable driving force to the turntable 10 and achieves precise indexing of the turntable 10's rotation.

[0055] like Figure 7 As shown, the cam divider 50 includes a camshaft 51 and an output shaft 52. The camshaft 51 is connected to the rotary motor 40, the camshaft 51 is connected to the output shaft 52, and the output shaft 52 is connected to the turntable 10.

[0056] Specifically, the rotating motor 40 is equipped with a pulley 41, and the pulley 41 and the camshaft 51 are connected by a belt drive.

[0057] It is worth noting that the output shaft 52 is rotated or stopped at specific points in time by means of the camshaft 51, thereby achieving intermittent motion.

[0058] like Figure 7 As shown, the cam divider 50 also includes an angle sensor 53 and an angle sensing rotor 54. The angle sensing rotor 54 is sleeved on the camshaft 51, and the angle sensor 53 is set corresponding to the angle sensing rotor 54. The lifting feeder also includes a control component 60. The control component 60 is electrically connected to the angle sensor 53, electrically connected to the lifting component 30, and electrically connected to the rotating motor 40.

[0059] It is worth noting that, through the cooperation of the angle sensing rotor 54 and the angle sensor 53, the angle electrical signal is sent to the control component 60. The control component 60 transmits signals to the rotating motor 40 and the control component 60 to control the turntable 10 to rotate at a fixed time and angle.

[0060] Specifically, the control component 60 is electrically connected to the servo motor 35 in the lifting component 30. The servo motor 35 transmits the position electrical signal of the lifting block 311 to the control component 60. The control component 60 analyzes the electrical signal and controls the timing and duration of energizing the servo motor 35, thereby realizing the raising or lowering of the lifting block 311.

[0061] Furthermore, the control component 60 is also electrically connected to the side-mounted omnidirectional robotic arm 90, and the program execution cycle in the control component 60 is cyclically performed based on the electrical signals of the rotation sensor 53 and the movement of the side-mounted omnidirectional robotic arm 90.

[0062] Specifically, each time the angle sensing rotor 54 approaches the angle sensor 53, it generates an angle electrical signal. The angle sensor 53 transmits the angle electrical signal to the control component 60. The control component 60 analyzes the angle electrical signal and controls the timing and duration of energizing the rotating motor 40, thereby realizing programmed control of the turntable 10 to achieve timed and angled rotation.

[0063] Furthermore, in this embodiment, the rotation angle of the turntable 10 is 60° each time.

[0064] like Figure 1 As shown, the lifting and feeding machine also includes a base 70, and the control component 60, lifting component 30 and cam divider 50 are all mounted on the base 70.

[0065] Specifically, the lifting and feeding machine includes a power supply 71, which is electrically connected to the control component 60, the lifting component 30, the rotating motor 40 and the cam divider 50 to provide stable power. The power supply 71 has the functions of voltage transformation, voltage stabilization and turbulence protection and power failure protection.

[0066] In the lifting and feeding machine of this embodiment, after the side-mounted omnidirectional robotic arm 90 picks up the metal sheet and leaves the stacking slot 21, the side-mounted omnidirectional robotic arm 90 sends an electrical signal to the control component 60. The control component 60 controls the servo motor 35 to raise the lifting block 311, so that the uppermost metal sheet is at the picking height of the side-mounted omnidirectional robotic arm 90. When all the metal sheets in a stacking slot 21 are removed, the control component 60 controls the servo motor 35 to lower and reset the lifting block 311 to the underside of the turntable 10. Then, the control component 60 controls the rotation motor 40 to control the turntable 10 to rotate. When the turntable 10 rotates to a specified angle, the angle sensor 53 sends an electrical signal to the control component 60. The control component 60 controls the servo motor 35 to raise the lifting block 311, so that the uppermost metal sheet is at the picking height of the side-mounted omnidirectional robotic arm 90. The above cycle is repeated to achieve continuous feeding production with one loading cycle.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
