Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to a motor rotor circulating feeding mechanism. Background Art

[0002] The motor rotor is the rotating part of the motor. Typically consisting of an inner core and coils wound around it, the rotor generates or receives electrical energy through rotation. As a key component in the motor, the rotor is essential for converting electrical energy into mechanical energy. Rotor assembly is a crucial core step in the motor assembly process, and its efficiency and quality are crucial to motor production.

[0003] With the continuous development of automation and robotics technology, more and more motor assembly lines are beginning to use robotic arms to feed motor rotors. The robotic arms use preset programs and paths to grab the rotors from the material storage area and accurately place them on the assembly station.

[0004] The design and layout of material storage areas have a direct impact on the flow and supply of materials. Existing material storage areas often have irrational layouts, complex transportation routes, or interference with other equipment, which hinders refilling and circulating material supply, impacting production efficiency. Utility Model Content

[0005] In order to solve the problems existing in the background technology, the utility model provides a motor rotor circulating feeding mechanism, which includes a movable feeding bracket and a double-layer feeding mechanism and a three-axis moving mechanism installed on the movable feeding bracket, wherein:

[0006] The double-layer loading mechanism includes a double-layer material base, the upper layer of the double-layer material base is provided with an upper motor, a sliding upper guide rail and an upper tray; the output shaft of the lower motor is connected to the screw rod, and the bottom of the upper tray is connected to the screw rod through a slider; the lower layer of the double-layer material base is provided with a lower motor, a sliding lower guide rail and a lower tray; the output shaft of the lower motor is connected to the screw rod, and the bottom of the upper tray is connected to the screw rod through a slider;

[0007] The three-axis moving mechanism includes an X-axis moving mechanism, a Y-axis moving mechanism, and a Z-axis moving mechanism that are slidably connected to each other. The Z-axis moving mechanism is equipped with a clamping mechanism, which includes a connecting base that is slidably connected to the Z-axis moving mechanism along the Z-axis direction, and a manipulator is installed at the bottom of the connecting base;

[0008] An assembly table is provided in front of the movable loading bracket and below the X-axis moving mechanism.

[0009] In a preferred solution, the assembly platform includes a support beam and a mounting seat disposed above the support beam for assembling the rotor.

[0010] In the preferred solution, the X-axis moving mechanism is connected to the mobile loading bracket through a column, and the front end of the X-axis moving mechanism extends out of the mobile loading bracket; the Y-axis moving mechanism is connected to the X-axis moving mechanism by sliding along the X-axis direction, and the Z-axis moving mechanism is connected to the Y-axis moving mechanism by sliding along the Y-axis direction.

[0013] The beneficial effects achieved by the utility model are:

[0014] First, the present invention designs upper and lower trays. Each tray is driven by a screw rod driven by an upper and lower motor 17, causing the tray to slide along a guide rail. This motor drives the rotor on the tray to automatically move forward or backward, facilitating grabbing by a robotic arm or gripping mechanism. While the robotic arm is retrieving material from the front tray, the other tray can be moved to the rear to refill. During this refilling process, the rotor's shaft is secured by inserting through holes in the tray, ensuring stability and accuracy of the rotor on the tray.

[0015] Second, the utility model designs a three-axis moving mechanism, which consists of an X-axis moving mechanism, a Y-axis moving mechanism and a Z-axis moving mechanism, and the three are connected by sliding to achieve multi-degree-of-freedom movement. The X-axis moving mechanism slides along the column of the mobile feeding bracket, the Y-axis moving mechanism slides along the X-axis moving mechanism, and the Z-axis moving mechanism slides along the Y-axis moving mechanism. Through this combination of three-axis movement, the clamping mechanism can be precisely positioned in three-dimensional space so as to accurately clamp, transport or place the rotor. The clamping mechanism includes a connecting seat and a manipulator. The connecting seat is connected to the Z-axis moving mechanism by sliding along the Z-axis direction, and the manipulator is installed at the bottom of the connecting seat. The manipulator can open and close according to the preset program and path to clamp or release the rotor. The manipulator works in coordination with the three-axis moving mechanism to grab the rotor from the double-layer feeding mechanism through precise control and transport it to the mounting seat on the assembly table. The entire device has a reasonable layout and high feeding and assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figures 1-6 The utility model provides a motor rotor 6 circulating feeding mechanism, which includes a movable feeding bracket 2 and a double-layer feeding mechanism 1 and a three-axis moving mechanism 3 installed on the movable feeding bracket 2, wherein:

[0026] The double-layer loading mechanism 1 includes a double-layer material base 11. The upper layer of the double-layer material base 11 is provided with an upper motor 16, a slidingly connected upper guide rail 12 and an upper tray 13; the output shaft of the lower motor 17 is connected to the screw rod, and the bottom of the upper tray 13 is connected to the screw rod through a slider; the lower layer of the double-layer material base 11 is provided with a lower motor 17, a slidingly connected lower guide rail 14 and a lower tray 15; the output shaft of the lower motor 17 is connected to the screw rod, and the bottom of the upper tray 13 is connected to the screw rod through a slider;

[0027] The three-axis moving mechanism 3 includes an X-axis moving mechanism 31, a Y-axis moving mechanism 32, and a Z-axis moving mechanism 33 that are slidably connected to each other. The Z-axis moving mechanism 33 is equipped with a gripping mechanism 4. The gripping mechanism 4 includes a connecting base 41 that is slidably connected to the Z-axis moving mechanism 33 along the Z-axis direction. A manipulator 42 is installed at the bottom of the connecting base 41.

[0028] An assembly platform 5 is provided in front of the movable loading bracket 2 and below the X-axis moving mechanism 31. The assembly platform 5 includes a support beam 51 and a mounting seat 52 provided above the support beam 51 for assembling the rotor 6.

[0029] The X-axis moving mechanism 31 is connected to the mobile loading bracket 2 through a column, and the front end of the X-axis moving mechanism 31 extends out of the mobile loading bracket 2; the Y-axis moving mechanism 32 is connected to the X-axis moving mechanism 31 by sliding along the X-axis direction, and the Z-axis moving mechanism 33 is connected to the Y-axis moving mechanism 32 by sliding along the Y-axis direction.

[0030] The upper tray 13 and the lower tray 15 are each provided with a plurality of through holes, and the shaft of the rotor 6 is fixed in the upper tray 13 and the lower tray 15 by being inserted into the through holes. The number of rows and columns of through holes provided in the upper tray 13 and the lower tray 15 are both 10 rows and 9 columns.

[0031] The working process of this utility model is as follows:

[0032] The double-layer loading mechanism 1 comprises an upper tray 13 and a lower tray 15, each of which is provided with a plurality of through holes for fixing the shaft of the rotor 6. The trays are connected to the screw rods through sliders, and the screw rods are driven by the corresponding upper motor 16 or lower motor 17.

[0033] The two trays are staggered, and a worker or an automatic feeding mechanism replenishes the rotor 6 on the tray at the rear. When the rear tray is filled with rotors 6, the corresponding motor (such as the upper motor 16) starts, driving the screw to rotate, which in turn drives the tray to slide forward along the guide rail to the material removal position; at the same time, the motor corresponding to the other tray (such as the lower motor 17) starts, driving the screw to rotate, which in turn drives the tray to slide backward along the guide rail to the feeding position for feeding.

[0034] When the rotor 6 on the tray is fully replenished, the motor stops working and the tray remains stationary, waiting for the clamping mechanism 4 to come and take the material.

[0035] The X-axis moving mechanism 31 is connected to the mobile loading support 2 by a column and can slide in the horizontal direction along the column. This step enables the clamping mechanism 4 to move left and right on the horizontal plane to aim at the specific rotor 6 in the double-layer loading mechanism 1.

[0036] The Y-axis moving mechanism 32 slides along the X-axis moving mechanism 31, allowing the clamping mechanism 4 to move in a direction perpendicular to the X-axis. This step further adjusts the position of the clamping mechanism 4 so that it approaches the target rotor 6 more accurately.

[0037] The Z-axis movement mechanism 33 slides along the Y-axis movement mechanism 32, achieving vertical movement. During this step, the connecting base 41 and manipulator 42 of the gripping mechanism 4 descend to an appropriate height. When the gripping mechanism 4 reaches the target rotor 6 position, the manipulator 42 opens and closes according to a pre-set program and path to grip the rotor 6. The rotor 6's shaft is secured through holes in the tray, ensuring stability and accuracy during the gripping process.

[0038] After the robot 42 grasps the rotor 6, the three-axis motion mechanism 3 works in conjunction to move the rotor 6 to the assembly table 5 in front of the mobile loading bracket 2. During this process, the X-axis, Y-axis, and Z-axis motion mechanisms 33 move as needed to ensure that the rotor 6 is accurately placed on the mounting seat 52 on the assembly table 5.

[0039] After the rotor 6 is transported to the assembly table 5, workers or automatic assembly equipment begin to assemble the rotor 6. The assembly table 5 provides a stable working platform and a mounting base 52 to ensure that the rotor 6 can be assembled accurately and efficiently.

[0040] When the rotor 6 on a tray on a certain layer (such as the upper tray 13) is taken away by the clamping mechanism 4, the corresponding motor (such as the upper motor 16) is started, driving the screw to rotate, thereby driving the tray to slide backward along the guide rail to move to the feeding position to start feeding. This cycle continues.

[0041] The motor rotor 6 cyclic feeding mechanism of the present invention achieves efficient and stable feeding and assembly of the motor rotor 6 through automatic feeding by the double-layer feeding mechanism 1, precise positioning by the three-axis movement mechanism 3, and flexible gripping and handling by the gripping mechanism 4. This mechanism design greatly improves the automation level and production efficiency of the motor production line.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
