[0035] The utility model will be described below in conjunction with the drawings.

[0036] The specific scheme adopted is:

[0037] As shown in Figures 1-4 The utility model provides a hollow metal part automatic material collecting device, including conveyer belt conveying mechanism 1, electromagnetic adsorption material taking device 2 and lifting type material receiving platform 3;

[0038] Conveyer belt conveying mechanism 1 is used for transmitting workpiece 7, and position sensor 10 is arranged thereon to be used for monitoring workpiece 7 reaches the preset position;

[0039] Electromagnetic adsorption material taking device 2 is located on the upside of the preset position, when workpiece 7 comes to the preset position, it drops and magnetically adsorbs workpiece 7 and moves to the upside of lifting type material receiving platform 3;

[0040] Lifting type material receiving platform 3 includes material receiving disc 30 and guide column 31, material receiving disc 30 can linearly move along guide column 31, so that workpiece 7 has consistent drop height when each workpiece 7 is released, to reduce the impact collision of workpiece 7.

[0041] The above structure realizes the adsorption of metal parts by the on-off of electromagnet 24, which is more gentle than mechanical hand clamping, can significantly reduce the damage to the surface of the parts, especially for parts with high surface precision requirements, this advantage is particularly obvious, the lifting type material receiving platform 3 ensures that each part has a consistent landing height when released, effectively avoiding the heavy landing and impact between parts, further reducing the potential damage of the parts, the whole material receiving process is highly automated, from the conveyor belt conveying, electromagnetic adsorption material taking to the precise placement of the lifting type material receiving platform 3, all without manual intervention, significantly improving the production efficiency, the real-time monitoring of position sensor 10 and the quick response of electromagnetic adsorption material taking device 2 ensure that the workpiece 7 can be immediately adsorbed and transferred to the material receiving platform after reaching the preset position, reducing the waiting time, the maintenance of the device is more simple, the failure rate is lower, and the maintenance cost is reduced.

[0042] As a preferred embodiment of the present application, referring to Figure 1 , the lifting type material receiving platform 3 is arranged on both sides of the conveyor belt conveying mechanism 1, and the electromagnet 24 adsorption material taking device can move horizontally to place the workpiece 7 on the lifting type material receiving platform 3 on both sides. The electromagnetic adsorption material taking device 2 comprises a lifting cylinder 20, the lifting cylinder 20 is arranged on a cross beam 21, the piston rod of the lifting cylinder 20 is connected to a mounting disc 22, the mounting disc 22 is installed with multiple electromagnets 24, the electromagnets 24 can correspond to the non-hollow area of the workpiece 7 in the vertical direction to perform the adsorption and material taking operation.

[0043] The specific working process is as follows: the workpiece 7 is first transmitted by the conveyor belt conveying mechanism 1, when the workpiece 7 reaches the preset position, the position sensor 10 will send a signal. After receiving the signal, the electromagnet 24 adsorption material taking device starts to work. The device is driven to lift by the lifting cylinder 20, the lifting cylinder 20 is installed on the Y-axis slide plate, and the Y-axis slide plate is connected with the cross beam 21 through the sliding block and guide rail 210. The Y-axis slide plate is also connected with the driving structure, for example, a motor is arranged on the back of the Y-axis slide plate, a rack is arranged on the cross beam 21, the teeth of the motor output shaft are matched with the rack, or referring to Figure 2 , a tooth belt is arranged on the cross beam 21, the tooth belt is fixedly connected with the Y-axis slide plate, the tooth belt is driven to rotate by the motor, and the Y-axis slide plate is linearly moved, the transverse moving mode of the electromagnet 24 adsorption material taking device can also adopt other existing modes, which will not be described herein.

[0044] The piston rod of the lifting cylinder 20 is connected to a mounting disc 22, on which a plurality of electromagnets 24 are mounted. These electromagnets 24 can accurately correspond to the non-hollow area of the workpiece 7 in the vertical direction, and can generate a magnetic force to attract the workpiece 7 by being energized. After the electromagnets 24 attract the workpiece 7, the Y-axis sliding plate drives the electromagnet 24 to move to the appropriate lifting material receiving platform 3 above the cross beam 21. Subsequently, the lifting cylinder 20 is lowered, the electromagnets 24 are de-energized to release the workpiece 7 onto the material receiving disc 30. The lifting material receiving platform 3 is arranged on both sides of the conveying belt, and multiple lifting material receiving platforms 3 can be arranged according to needs, which significantly improves the storage capacity and space utilization.

[0045] In order to enable the electromagnetic material taking device to adapt to different part sizes, in one embodiment, the mounting disc 22 is provided with a first waist-shaped hole 220, the electromagnets 24 are fixed to the mounting member 23, and the first bolts pass through the first waist-shaped hole 220 to connect the mounting member 23. The position of the first bolt in the first waist-shaped hole 220 is adjusted to adjust the position of the electromagnet 24 relative to the mounting disc 22, so as to realize the adsorption of workpieces 7 of different sizes.

[0046] In another embodiment, referring to Figure 3 , a second waist-shaped hole 230 is designed on the mounting member 23. The electromagnets 24 are connected with the mounting member 23 by passing through the second waist-shaped hole 230 through the second bolts. In this way, by adjusting the position of the second bolt in the second waist-shaped hole 230, the specific position of the electromagnet 24 relative to the mounting member 23 can be adjusted more finely, and the cooperation of the first waist-shaped hole 220 and the second waist-shaped hole 230 provides greater flexibility and range for the position adjustment of the electromagnet 24. The design of the double waist-shaped holes enables the electromagnet 24 to not only adjust the position in one direction, but also fine-tune in the other direction, thereby ensuring that the electromagnet 24 can accurately align with the non-hollow area of workpieces 7 of different sizes and realize stable and effective adsorption.

[0047] In addition, outer ring electromagnets and inner ring electromagnets can be arranged on the mounting disc 22, which can simultaneously collect larger parts and smaller parts and store them in different lifting material receiving platforms 3, respectively. The on-off of the electromagnets 24 is a prior art (wires, switches and power supply accessories, not shown in the figure), which can be understood by those skilled in the art.

[0048] As a preferred embodiment of the present application, the material receiving disc 30 is connected to a lead screw lifting mechanism 32 to realize accurate lifting of a preset distance.

[0049] Specifically, the screw lifting mechanism 32 is composed of a screw, a moving part (nut seat or sliding block), a servo motor and other components. When the screw rotates, the moving part moves along the axial direction of the screw. The receiving tray 30 is connected to the moving part directly or through a connecting piece, ensuring that the vertical movement of the moving part can drive the lifting of the receiving tray 30. By controlling the rotation angle and speed of the motor, the rotation of the screw can be accurately controlled, and thus the moving distance of the moving part can be accurately controlled. By programming the rotation angle (or pulse number) of the servo motor, the moving distance of the screw lifting mechanism 32 can be accurately controlled, which is a prior art, thereby realizing the preset distance lifting of the receiving tray 30.

[0050] The position sensor 10 on the conveyor belt conveying mechanism 1 is used to monitor whether the workpiece 7 reaches the preset material taking position. When the workpiece 7 reaches the preset position, the electromagnetic adsorption material taking device is lowered and magnetically adsorbs the workpiece 7. Then the electromagnetic adsorption material taking device moves horizontally to transport the workpiece 7 to above the receiving tray 30. The electromagnet 24 is powered off to release the workpiece 7 onto the receiving tray 30. At this time, the control system 6 triggers the servo motor to start rotating, and the receiving tray 30 is lowered by the screw lifting mechanism 32 according to the preset distance. The above process is repeated every time a part is received, and the receiving tray 30 is gradually lowered to ensure that each part has a consistent landing height.

[0051] Further, a first laser sensor 4 at a higher position and a second laser sensor 5 at a lower position are arranged on one side of the guide column 31. When the laser light sources of the two laser sensors are simultaneously blocked by the workpiece 7, the receiving tray 30 reaches the full material state, and the receiving is stopped. Then the electromagnetic adsorption material taking device 2 places the material on the receiving platform that is not fully loaded.

[0052] In the preferred implementation, referring to Figure 4 , the guide column 31 is provided with two guide columns, and the receiving tray 30 is provided with a moving groove 300. The guide column 31 can move relative to the moving groove 300, for example, the bottom end of the guide column 31 can be connected to the sliding rail through a sliding block, and adjusted and fixed manually. Of course, it can also be an automatic moving mode, allowing the distance between the two guide columns 31 to be adjusted flexibly according to the size of the hollow area of the workpiece 7 to ensure that the workpiece 7 can be stacked stably and accurately, avoiding the problem of misaligned stacking of the workpiece 7, and improving the stability and accuracy of stacking. Misaligned stacking often leads to friction and collision between parts, increasing the risk of part damage. By ensuring that the workpiece 7 is overlapped and stacked, the friction and collision are effectively reduced, and the surface quality and integrity of the parts are protected.

[0053] As a preferred embodiment of the present application, in order to ensure that the electromagnetic adsorption material taking device 2 can accurately adsorb the workpiece 7 at the preset position, and at the same time prevent the workpiece 7 from leaving the preset position before being taken away, a material blocking plate 11 is arranged on the conveying belt conveying mechanism 1, and by accurately adjusting the position and angle of the material blocking plate 11, the stability and accuracy of the workpiece 7 at the preset position can be further ensured.

[0054] As a preferred embodiment of the present application, a control system 6 is further included, the electromagnetic adsorption material taking device 2 and the lifting material receiving platform 3 are electrically connected to the control system 6, the position signal detected by the position sensor 10 is transmitted to the control system 6, and the control system 6 controls the operation of the electromagnetic adsorption material taking device 2 and the lifting material receiving platform 3. The automation control of the whole material receiving process is realized. Not only the production efficiency is improved, but also the labor amount and the possibility of human error are significantly reduced.

[0055] The parts not described in the present application can be realized by using or referring to the existing technology.

[0056] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, and these should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
