Description

Technical Field

[0001] The present invention relates to the field of silicon steel sheet conveying, and in particular to a silicon steel sheet stacking and conveying platform for new energy vehicle motors. Background Art

[0002] The iron core of the new energy vehicle motor is constructed of silicon steel sheets. The silicon steel sheets are formed into a specific shape by punching, and then the quantitatively stacked silicon steel sheets are pressed into the iron core through a laminating machine. Several annular winding slots are punched out on the surface of the silicon steel sheets. In order to facilitate the precise stacking and positioning of the silicon steel sheets, welding and fixation, or the precise assembly of the iron core in the later stage, it is necessary to punch out notches on the edges of the silicon steel sheets. When the silicon steel sheets are stacked, the winding slots and notches of the stacked silicon steel sheets need to be aligned to ensure the forming quality of the iron core.

[0003] At present, the silicon steel sheets after punching are transferred to the stacking process manually or by conveying equipment. The precise alignment and stacking of the silicon steel sheets still rely on manual adjustment. The processing efficiency is low and position errors are prone to occur. It is difficult to achieve the function of automatically and neatly stacking and transporting the silicon steel sheets between the punching process and the stacking process. Summary of the Invention

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-11 As shown, the silicon steel sheet stacking and conveying platform for new energy vehicle motors includes a feeding component, a discharge conveyor belt 2 and a stacking component 4;

[0037] The feeding assembly includes a feeding conveyor belt 1, such as Figure 1 As shown, the suspension platform 3 is fixedly set at the discharge end of the feeding conveyor belt 1, and the suspension platform 3 is kept flush with the feeding conveyor belt 1. A circular blanking port 32 is opened at the end of the suspension platform 3, and a guide plate 31 is fixed on the edge of the suspension platform 3. The guide plate 31 gradually gathers toward the blanking port 32. The stamped silicon steel sheets are transported in a straight line by the feeding conveyor belt 1, and the silicon steel sheets are transferred to the surface of the suspension platform 3. After being guided by the guide plate 31, the silicon steel sheets fall one by one from the blanking port 32.

[0038] like Figure 2 As shown, the height of the discharge conveyor belt 2 is lower than that of the feed conveyor belt 1, so that the discharge conveyor belt 2 passes under the blanking port 32. The pulleys at both ends of the discharge conveyor belt 2 are composed of two coaxial fixed pulleys. The belt body of the discharge conveyor belt 2 is composed of two symmetrically distributed strip belts 21. The strip belts 21 are sleeved on the outside of the coaxial pulleys. The pulleys are driven by a motor to drive the two strip belts 21 to move synchronously. A number of carrier rods 22 are equidistantly arranged between the two strip belts 21. The two ends of the carrier rods 22 are fixedly connected to the strip belts 21. The spacing between adjacent carrier rods 22 is less than the diameter of the silicon steel sheet.

[0039] like Figure 2As shown, the stacking assembly 4 is arranged below the blanking port 32 and is mounted on the surface of the lifting structure. The stacking assembly 4 includes a vertically arranged wall panel 5, which is fixed to the basic structure of the feeding conveyor belt 1. A slide rail is vertically arranged on the surface of the wall panel 5. A cross frame 51 is arranged through the middle of the discharge conveyor belt 2. The cross frame 51 is connected to the slide rail through a slider. The basic structure of the feeding conveyor belt 1 is equipped with a cylinder 52. The telescopic end of the cylinder 52 is connected to the cross frame 51 for driving the cross frame 51 to move up and down.

[0040] like Figure 3-4 As shown, the stacking assembly 4 includes a positioning column 41, which is cylindrical. The horizontal frame 51 is integrally fixed with a base 48. The bottom of the positioning column 41 is fixedly connected to the base 48 by screws. The cone 42 is rotatably mounted on the top of the positioning column 41, with the tip of the cone 42 facing upward. The maximum diameter of the bottom of the cone 42 is consistent with the diameter of the positioning column 41. The cone 42 is connected to a drive assembly.

[0041] The outer surface of the positioning column 41 is provided with a winding slot clamp 44 and a notch slot clamp 45. The distribution positions of the winding slot clamp 44 and the notch slot clamp 45 are consistent with the distribution of the winding slots and notch slots on the surface of the silicon steel sheet. The top ends of the winding slot clamp 44 and the notch slot clamp 45 are located at the connection position between the cone 42 and the positioning column 41. The positioning column 41 is connected to a carrier 46, which is used to carry the stacked silicon steel sheets.

[0042] The silicon steel sheet conveying process is as follows:

[0043] The feeding conveyor belt 1 transports the silicon steel sheets and drops them one by one from the blanking port 32. In the initial state, the cylinder 52 drives the cross frame 51 to move upward, so that the positioning column 41 passes upward between the two carrier rods 22, and the carrier 46 is kept higher than the carrier rod 22. The falling silicon steel sheet is sleeved on the outside of the cone 42 and is blocked by the top of the winding slot clamp 44 and the notch slot clamp 45. The cone 42 is driven by the driving assembly to rotate, so that the silicon steel sheet dynamically adjusts its angle. When the winding slot and the notch slot of the silicon steel sheet are aligned with the winding slot clamp 44 and the notch slot clamp 45 respectively, the silicon steel sheet slides downward to the outside of the positioning column 41 under the action of gravity, and is carried by the carrier 46 for stacking. The angle of the silicon steel sheet is positioned by the winding slot clamp 44 and the notch slot clamp 45, so that the angle of the stacked silicon steel sheets remains consistent.

[0044] The cylinder 52 is turned on to push the cross frame 51 downward, causing the positioning column 41, the carrier 46 and the silicon steel sheet to descend as a whole. When the carrier 46 descends below the carrier rod 22, the silicon steel sheet is separated from the carrier 46 and is carried by two adjacent carrier rods 22. The positioning column 41 is continuously pushed downward until the cone 42 is lower than the carrier rod 22 and the downward movement is stopped. The discharge conveyor 2 is turned on to convey the stacked silicon steel sheets toward the lamination process.

[0045] When stacking the silicon steel sheets for the next time, the positioning posts 41 are kept aligned between the adjacent carrier rods 22, and the positioning posts 41 are pushed up again by the cylinder 52. Therefore, the working logic of the discharge conveyor belt 2 and the cylinder 52 is controlled by programming the controller to ensure that the cylinder 52 drives the positioning posts 41 to fully descend before the discharge conveyor belt 2 is started to transport forward to a fixed position, ensuring that the positioning posts 41 correspond to the gap between the carrier rods 22 after the discharge conveyor belt 2 is transported and fed.

[0046] like Figure 5 As shown, the driving assembly includes a torsion motor 53, a transmission shaft 43 rotatably mounted inside the positioning column 41, the top of the transmission shaft 43 is fixed to the cone 42, the bottom of the transmission shaft 43 passes through the base 48 and is fixedly mounted on the driven gear 55, the surface of the cross frame 51 is rotatably mounted on the half gear 54, the half gear 54 is meshed with the driven gear 55, the torsion motor 53 is mounted on the surface of the cross frame 51, and the output shaft of the torsion motor 53 is connected to the shaft of the half gear 54 by a transmission belt 56, and the transmission belt 56 has two pulleys and a belt body connecting the pulleys.

[0047] The torsion motor 53 is turned on to work, and the half gear 54 is driven to rotate through the transmission belt 56. The half gear 54 intermittently engages with the driven gear 55 to rotate, so that the transmission shaft 43 drives the cone 42 to rotate intermittently. The intermittent rotation of the cone 42 is used to drive the silicon steel sheet to adjust the angle. The intermittent rotation also makes the silicon steel sheet move irregularly, and the silicon steel sheet shakes and slides downward more easily. Since the half gear 54 is intermittently engaged with the driven gear 55, the torsion motor 53 is subjected to intermittent load impact. Power is transmitted through the transmission belt 56. The load impact on the torsion motor 53 can be reduced by slight slippage of the transmission belt 56, thereby reducing the failure rate of the torsion motor 53.

[0048] like Figure 6 As shown, multiple card slots 410 are vertically opened on the edge of the positioning column 41, and the card slots 410 extend to the top of the positioning column 41. The winding slot card plate 44 and the notch slot card plate 45 are fixed with a card handle 411. The winding slot card plate 44 and the notch slot card plate 45 are assembled on the surface of the positioning column 41 by sliding the card handle 411 vertically into the card slot 410.

[0049] like Figure 8-9 As shown, the tops of the winding slot clamp 44 and the notch slot clamp 45 are both chamfered to facilitate the sliding of the winding slot and notch slot of the silicon steel sheet on the outside of the winding slot clamp 44 and the notch slot clamp 45. The winding slot clamp 44 has ribs that abut the three sides of the winding slot of the silicon steel sheet, so that the winding slot clamp 44 forms a three-point abutment with the winding slot, thereby improving the positioning accuracy. The two side edges of the notch slot clamp 45 abut the two side walls of the notch slot of the silicon steel sheet, ensuring that the notch slot clamp 45 is aligned with the notch slot of the silicon steel sheet, thereby comprehensively realizing the precise alignment of the angles of the stacked silicon steel sheets.

[0050] like Figure 7 As shown, vertically extending chute 49 is symmetrically provided on the side wall of the positioning column 41. The carrier 46 has a circular portion with two T-shaped portions symmetrically distributed on the edge of the circular portion. The circular portion of the carrier 46 slides on the inner side of the positioning column 41. The T-shaped portion of the carrier 46 passes through the chute 49 to the outer side of the positioning column 41, and the silicon steel sheet is supported by the T-shaped portion. A pressure sensor 47 is installed at the bottom of the chute 49. A spring is provided between the carrier 46 and the pressure sensor 47. The pressure sensor 47 is connected to the cylinder 52 of the lifting structure and the discharge conveyor belt 2 through a controller.

[0051] The weight of a single stack of silicon steel sheets is set by the controller, and the stacked silicon steel sheets are carried by the carrier 46. The weight borne by the carrier 46 acts on the pressure sensor 47 through the spring. The pressure sensor 47 detects that the weight reaches the set value, and the controller controls the cylinder 52 to push the cross frame 51 and the entire stacking assembly 4 down. When the silicon steel sheets are transferred to the surface of the carrier rod 22, the discharge conveyor 2 is turned on to transport the neatly stacked silicon steel sheets.

[0052] like Figure 10-11 As shown, a notch is provided on the material-facing side of the blanking opening 32, and a baffle 61 is provided inside the notch for elastic rotation by a torsion spring. In a free state, the end of the baffle 61 close to the blanking opening 32 is tilted by the elastic force of the torsion spring. An L-shaped limit frame 62 is fixed to the bottom of the suspension platform 3. The limit frame 62 is used to block and limit the maximum rotation angle of the baffle 61 by hooking the baffle 61. A feeler rod 6 is fixed to the surface of the horizontal frame 51, and the feeler rod 6 is aligned upwardly with the end of the baffle 61 away from the blanking opening 32.

[0053] The cylinder 52 drives the cross frame 51 to drive the entire stacking assembly 4 to move upward during the stacking process. The cross frame 51 drives the feeler rod 6 to move upward synchronously. The top of the feeler rod 6 contacts the baffle 61, so that the baffle 61 overcomes the elastic force and rotates to be flush with the suspension platform 3, ensuring that the silicon steel sheets can be smoothly transmitted to the blanking port 32 and fall. When the cross frame 51 drives the stacking assembly 4 to descend and transfer the stacked silicon steel sheets to the surface of the discharge conveyor belt 2, the feeler rod 6 synchronously descends and separates from the baffle 61. Under the action of the elastic force, the baffle 61 rotates and tilts up to prevent the silicon steel sheets from entering the blanking port 32, thereby achieving the effect of automatically pausing the material guide and maintaining the orderly conduction, stacking and transportation of the silicon steel sheets.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
