Description

Technical Field

[0001] This invention relates to the field of motor assembly and transfer technology, and in particular to a lifting and tilting device for motor assembly. Background Technology

[0002] After the traditional motor windings and frame are press-fitted by a press machine, the next step is to move them to the assembly line for assembly. Since the motor is placed vertically on the press-fitting fixture on the press machine, it needs to be placed horizontally on the assembly line fixture. To meet this requirement, the motor windings and frame are usually manually transferred to the assembly line for assembly after being press-fitted by the press machine. This allows for manual adjustment of the motor's position. Currently, the commonly used transfer tool is a transfer trolley. However, the transfer trolley not only occupies walking space in the workshop, but also has slow transfer efficiency and affects production efficiency. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a lifting and tilting device for motor assembly.

[0004] The present invention discloses a lifting and tilting device for motor assembly, which is located between the conveyor line and the assembly line downstream of the press machine, and includes:

[0005] The transfer mechanism includes a first transfer unit and a second transfer unit connected to the first transfer unit;

[0006] The driving device includes a first driving mechanism and a second driving mechanism for driving the transfer mechanism to rise and fall. The first driving mechanism is used to drive the transfer mechanism to rotate between a first state and a second state. When the transfer mechanism is in the first state, the first transfer part is connected to the outlet end of the conveyor line. When the transfer mechanism is in the second state, the second transfer part is connected to the inlet end of the assembly line.

[0007] Preferably, the second transfer part is vertically fixed to the side of the first transfer part near the assembly line body, forming an L-shaped structure. The first transfer part includes multiple parallel first rotating rollers and a third motor capable of driving the first rotating rollers to rotate. The first ends of the multiple first rotating rollers are rotatably connected to one side frame of the first transfer part, and the second ends are rotatably connected to the opposite side frame of the first transfer part. The second transfer part includes multiple parallel second rotating rollers and a fourth motor capable of driving the second rotating rollers to rotate.

[0008] Preferably, a support plate is provided between the frame of the first transfer part and the frame of the second transfer part, and the first drive mechanism includes a first geared motor, the output end of the first geared motor is fixed to the support plate to drive the first transfer part to rotate.

[0009] Preferably, it also includes a frame, on which a vertical frame is provided on one side near the conveyor line. The second drive mechanism includes a second motor, a sprocket and chain transmission mechanism, and a movable frame. The first drive mechanism passes through the movable frame and is fixed to the support plate, and the first drive mechanism is rotatably connected to the movable frame. The second motor drives the movable frame to move up and down through the sprocket and chain transmission mechanism, thereby driving the first transfer part to move up and down. When the first transfer part is in the lower first position, the first transfer part is connected to the lower line entrance end of the conveyor line and places the pressing fixture plate back on the lower line. When the first transfer part is in the upper second position, the first transfer part is connected to the upper line exit end of the conveyor line to receive the motor stator placed on the pressing fixture plate after pressing.

[0010] Preferably, a guide mechanism is also provided between the movable frame and the vertical frame.

[0011] Preferably, the guiding mechanism includes a linear guide rail disposed on the vertical frame and a slider disposed on the movable frame, the slider extending into the linear guide rail.

[0012] Preferably, the upper end of the linear guide rail is also provided with a limit buffer.

[0013] Preferably, the side of the frame is also provided with a door panel that can be opened or closed.

[0014] Preferably, the rear end of the second transfer unit is further provided with an assembly tooling plate return transmission line, which is arranged perpendicularly to the lower part of the assembly line and is independently arranged.

[0015] In summary, the present invention has the following advantages: the motor stator after being pressed by the press machine enters the first transfer section through the upper part of the conveyor line. At this time, the first transfer section is in the first state. Then, the first drive mechanism is activated, which drives the transfer mechanism to rotate 90°. At this time, the first transfer section is in the second state. The second transfer section is connected to the entrance end of the assembly line. The motor stator of the first transfer section is rotated onto the second transfer section and then enters the assembly line from the second transfer section for assembly work. In this way, the pressed motor stator can automatically flow into the next process without leaving the line, without the need for manual transfer or changing the placement state, saving labor costs and improving transfer efficiency and production efficiency.

[0016] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1-2 As shown in this embodiment, a lifting and tilting device for motor assembly is provided between the conveyor line downstream of the press machine and the assembly line 1. The motor stator, after being press-fitted by the press machine, enters the conveyor line and then passes through the lifting and tilting device in this embodiment to enter the assembly line 1 and be tilted into a tilted position, eliminating the need for manual transfer and adjustment. Specifically, the lifting and tilting device in this embodiment includes:

[0022] The transfer mechanism includes a first transfer unit 2 and a second transfer unit 3 connected to the first transfer unit 2;

[0023] The driving device includes a first driving mechanism and a second driving mechanism for driving the transfer mechanism to rise and fall. The first driving mechanism is used to drive the transfer mechanism to rotate between a first state and a second state. When the transfer mechanism is in the first state, the first transfer part 2 is connected to the outlet end of the conveyor line. When the transfer mechanism is in the second state, the second transfer part 3 is connected to the inlet end of the assembly line 1.

[0024] Thus, the motor stator pressed by the press machine enters the first transfer section 2 through the upper part 13 of the conveyor line. At this time, the first transfer section 2 is in the first state. Then, the first drive mechanism is started, which drives the transfer mechanism to rotate 90°. At this time, the first transfer section 2 is in the second state. The second transfer section 3 is connected to the entrance end of the assembly line 1. The motor stator of the first transfer section 2 is rotated onto the second transfer section 3, and then enters the assembly line 1 from the second transfer section 3 for assembly line work. In this way, the press-pressed motor stator can automatically flow into the next process without leaving the line, without manual transfer or changing the placement state, saving labor costs and improving transfer efficiency and production efficiency.

[0025] Furthermore, such as Figure 1 As shown, the second transfer section 3 is vertically fixed to the side of the first transfer section 2 near the assembly line body 1, forming an L-shaped structure. The first transfer section 2 includes multiple parallel first rotating rollers 4 and a third motor (not shown) capable of driving the first rotating rollers 4 to rotate. The first ends of the multiple first rotating rollers 4 are rotatably connected to one side frame 6 of the first transfer section 2, and the second ends are rotatably connected to the opposite side frame 6 of the first transfer section 2. When the third motor is started, the multiple first rotating rollers 4 rotate simultaneously, facilitating the transport of the motor stator placed on them to the second transfer section 3. The second transfer section 3 includes multiple parallel second rotating rollers 5 and a fourth motor (not shown) capable of driving the second rotating rollers 5 to rotate. The first ends of the multiple second rotating rollers 5 are rotatably connected to one side frame of the second transfer section 3, and the second ends are rotatably connected to the opposite side frame of the second transfer section 3. When the fourth motor is started, the multiple second rotating rollers 5 rotate simultaneously, facilitating the transport of the motor stator placed on them to the assembly line body 1.

[0026] Furthermore, a support plate 7 is provided between the frame 6 of the first transfer section 2 and the frame of the second transfer section 3. The first drive mechanism includes a first geared motor 8, the output end of which is fixed to the support plate 7 to drive the first transfer section 2 to rotate. Specifically, starting the first geared motor 8 drives the support plate 7 to rotate, thereby driving the transfer mechanism to rotate 90°. Of course, the first geared motor 8 and the support plate 7 can also be connected by components such as a transmission shaft and bearings, depending on the specific situation. The first geared motor 8 can also be connected to a frequency converter and a photoelectric position sensor, enabling precise positioning and easy speed control. The frequency converter has strong compatibility, and one model can simultaneously meet the needs of multiple types of motors.

[0027] In this embodiment, as Figure 1As shown, it also includes a frame 9, on which a vertical frame 10 is provided on the side near the conveyor line. The second drive mechanism includes a second motor 11, a sprocket and chain transmission mechanism (not shown in the figure), and a moving frame 12. The first drive mechanism passes through the moving frame 12 and is fixed to the support plate 7, and the first drive mechanism is rotatably connected to the moving frame 12. The second motor 11 drives the moving frame 12 to move up and down through the sprocket and chain transmission mechanism, so as to drive the first transfer part 2 to move up and down. When the first transfer part 2 is in the lower first position, the first transfer part 2 is connected to the inlet end of the lower layer line 14 of the conveyor line and places the pressing tool plate back plate on the lower layer line 14. When the first transfer part 2 is in the upper second position, the first transfer part 2 is connected to the outlet end of the upper layer line 13 of the conveyor line to receive the motor stator placed on the pressing tool plate after pressing.

[0028] Specifically, the sprocket and chain transmission mechanism includes a sprocket and a chain that are meshed together. The output end of the second motor 11 is connected to the sprocket and drives the sprocket to rotate. The frame 6 of the first transfer part 2 is fixed to the chain. When the second motor 11 is started, the sprocket is driven to rotate. The chain meshes with the sprocket to drive the frame 6 to move up and down, thereby driving the first transfer part 2 to move up and down and adjusting the up and down position of the first transfer part 2.

[0029] Furthermore, to ensure the stability of the vertical movement of the first transfer unit 2, a guide mechanism is provided between the movable frame 12 and the vertical frame 10. Specifically, the guide mechanism includes a linear guide rail 15 on the vertical frame 10 and a slider 16 on the movable frame 12, with the slider 16 extending into the linear guide rail 15. A limit buffer 17 is also provided at the upper end of the linear guide rail 15 to limit and protect the first transfer unit 2.

[0030] In this embodiment, the side of the frame 9 is also provided with a door panel 18 that can be opened or closed, which facilitates installation and maintenance.

[0031] In summary, since the motor requires pressing and assembly fixtures during transport, the motor stator, after being pressed by the pressing machine, first enters the conveyor line. To facilitate the recycling of the pressing fixtures, the conveyor line includes an upper line 13 and a lower line 14. The upper line 13 transports the pressed motor stator to the first transfer section 2, while the lower line 14 transports the returned pressing fixtures. The upper and lower lines 13 transport in opposite directions. The lower line 14 transports the returned pressing fixtures to the entrance of the upper line 13, where they are manually placed on the upper line 13 to prepare for the next transport of pressed motor stators. After the motor stator is pressed, it enters the upper line 13 with the pressing fixtures already placed on it and is transported to the first transfer section 2. The first reduction motor 8 is then started, and the transfer mechanism rotates 90°. After pressing, the motor stator is flipped onto the second transfer section 3 and then enters the assembly tooling plate of the assembly line 1. (It should be noted that the rear end of the second transfer section 3 is also equipped with an assembly tooling plate return transmission line that is perpendicular to the assembly line 1 and located below it. The assembly line 1 has already placed the assembly tooling plate on the assembly line 1 in advance through the assembly tooling plate return transmission line.) The first reduction motor 8 is started again, which drives the transfer mechanism to flip back 90° again. At this time, the first transfer section 2 is back in the first state and is connected to the outlet end of the upper line 13. At this time, the second drive mechanism is started to drive the transfer mechanism down to the position of the lower line 14. The first transfer section 2 is connected to the inlet end of the lower line 14, and the pressing tooling plate (empty plate) on the first transfer section 2 is transported back through the lower line 14 to enter the next transport cycle. Similarly, after the assembly tooling plate on assembly line 1 drives the motor stator to be assembled, the assembly tooling plate is manually removed and placed on the assembly tooling plate return conveyor line as a return plate, and then transferred to the entrance end of assembly line 1 to enter the second transfer section 3 for use. This process is repeated continuously.

[0032] When using the motor assembly lifting and tilting device in this embodiment, the following steps are performed:

[0033] S1: The assembly tooling plate return conveyor connects the assembly tooling plate to the second transfer section 3, starts the first reduction motor 8, the transfer mechanism rotates 90°, starts the second motor 11, the first transfer section 2 moves to the outlet end of the upper line 13, and after pressing, the motor electronics enter the first transfer section 2.

[0034] S2: Start the first reduction motor 8, the transfer mechanism rotates 90°, the motor stator on the first transfer part 2 rotates to the assembly tooling plate that has been pre-connected to the second transfer part 3, and the assembly tooling plate of the second transfer part 3 carries the motor stator into the assembly line 1 for the next process.

[0035] S3: Start the second motor 11, the second transfer unit 3 moves to the lower layer, and connects to the returned assembly tooling plate;

[0036] S4: Start the first motor, the transfer mechanism rotates 90°, and sends the empty pressing tool plate on the first transfer part 2 back to the lower line body 14 as a return plate;

[0037] S5: Start the second motor 11, and the first transfer unit 2 moves to the outlet position of the upper line 13 to wait for the motor stator after pressing. This cycle repeats.

[0038] Preferably, for ease of control, the motor assembly lifting and tilting device in this embodiment may further include a control device, which is electrically connected to the first reduction motor 8, the second motor 11, the third motor and the fourth motor for convenient operation and control.
