Description

Technical Field

[0001] The invention relates to the field of material feeding and storage, and in particular to a balancing sheet material storage and feeding device. Background Art

[0002] The rotor is an important part of the compressor. In modern motors, when the rotor rotates around its axis, if the mass distribution relative to the axis is uneven, centrifugal force will be generated, causing noise and wear on the rotor bearings, thereby reducing the performance and life of the motor. In the motor manufacturing industry, in order to improve the dynamic balance of the compressor motor rotor, it is usually necessary to add a copper, zinc, or iron-based balancing sheet. This balancing sheet is generally a thin sheet of uniform size.

[0003] In the motor production process, usually a rotor needs to be installed with multiple balancing sheets. The rotor processing device continuously picks up the balancing sheets from the material picking station and then adds the balancing sheets to the rotor. At present, there is no mature mechanical automated material storage and feeding for thin sheets such as balancing sheets. Therefore, in the existing processing process, it is all carried out by manual feeding. Workers manually place the balancing sheets on the material picking station and wait for the rotor processing device to pick them up. This manual feeding method has many disadvantages. Workers need to constantly go back and forth between the front-end balancing sheet output device and the material picking station, and then place the balancing sheets on the material picking station after getting them. The operation is cumbersome, the feeding efficiency is low, and a large amount of labor is required. Excessive labor costs will increase the cost of life of the enterprise. At the same time, when the balancing sheets are manually placed at the material picking station, due to errors in manual operation, it is difficult to achieve accurate positioning of the balancing sheets when placing them at the material picking station, resulting in errors in the subsequent rotor processing device when picking up the balancing sheets from the material picking station, and errors when adding the balancing sheets to the rotor, which leads to reduced performance and life of the motor.

[0004] With the increasing requirements for efficiency and precision, simple manual feeding can no longer meet the use needs of balance sheets, especially when the production scale is large, which is not conducive to the long-term development of the enterprise. However, since the balance sheet is a thin sheet, it is difficult to grasp it by mechanical equipment such as mechanical claws, and there are problems such as instability in grasping. Therefore, a storage and feeding device for balance sheets is needed to overcome these problems and meet the needs of production. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a balancing sheet material storage and feeding device with convenient material storage, stable grasping and accurate material feeding.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A balancing sheet material storage and feeding device comprises a workbench bracket, a material taking workbench respectively arranged on the workbench bracket, a material storage mechanism, a main frame and a material feeding mechanism arranged on the main frame, the material storage mechanism comprises an inclined material storage slide and a material feeding station arranged at the lower outlet of the material storage slide, the material feeding station comprises a blocking plate, a docking block arranged in front of the blocking plate for receiving the current balancing sheet and a limiting column for blocking the subsequent balancing sheet by lifting, and the material feeding mechanism is arranged opposite to the material feeding station.

[0008] The material storage mechanism also includes a mounting support seat, a rotating mounting plate connected to the mounting support seat with an adjustable angle, a lifting cylinder mounting plate fixed on the rotating mounting plate, and a first lifting cylinder and a second lifting cylinder installed on the lifting cylinder mounting plate. The first lifting cylinder is used to drive the docking block to rise and fall, and the second lifting cylinder is used to drive the limit column to rise and fall. The blocking plate is fixed on the rotating mounting plate, and a first proximity sensor is arranged on the blocking plate to detect whether the balance plate is in place.

[0009] The lower outlet of the storage slide is fixed on the mounting support seat, and the upper inlet is installed on the workbench bracket through a connecting block and a lifting screw. The upper end of the lifting screw is hinged to the connecting block, and the lower end is fixedly connected to the workbench bracket. The maximum inclination angle of the storage slide is 30°.

[0010] The storage slide is provided with a plurality of sub-slides in parallel, and each sub-slide corresponds to a corresponding docking block, a first proximity sensor and a limit column.

[0011] A balancing plate pressing plate used to make the balancing plate slide down smoothly and a pressing plate mounting plate used to fix and adjust the height of the balancing plate pressing plate are arranged above the material storage slideway.

[0012] The feeding mechanism includes a linear module fixed to the main frame through a linear module mounting plate and a feeding robot arm that realizes linear motion on the linear module. The feeding robot arm includes a rotating cylinder, an extension cylinder, a clamping cylinder and a mechanical claw that are sequentially connected in transmission. The rotating cylinder is connected to the linear module through a rotating cylinder connecting seat, and the rotating cylinder is connected to the extension cylinder through a cylinder mounting seat to realize the swing of the feeding robot arm. The clamping cylinder is connected to the top of the extension cylinder through a cylinder connecting block to control the length of the feeding robot arm.

[0013] The feeding mechanical arm also includes an auxiliary clamping top block connected to the extension cylinder, and the auxiliary clamping top block matches the shape of the balance sheet to press against the upper surface of the balance sheet when the mechanical claw grabs the balance sheet.

[0014] The described material taking workbench includes a positioning rod, a positioning mounting plate fixed on the workbench bracket through the positioning rod, and a positioning block, a positioning baffle and a positioning cylinder respectively arranged on the positioning mounting plate. The positioning block is provided with a positioning groove for placing the balance piece, and a second proximity sensor is arranged at the corresponding position of the positioning groove. The positioning baffle is connected with the positioning cylinder and cooperates with the positioning groove to clamp and accurately position the balance piece.

[0015] The described main frame is an aluminum alloy frame, and a protective glass is arranged outside it. The workbench bracket is formed by welding carbon steel square tubes and is painted on the surface.

[0016] The operation process of this material storage and feeding device is as follows:

[0017] When the balance piece is conveyed by the previous station device to the inlet of the material storage slideway, the balance piece slides into the feeding station along each sub-slideway and abuts against the blocking plate. When the first proximity sensor detects that the docking block receives the balance piece, the first lifting cylinder lowers the docking block to form a feeding groove, and the second lifting cylinder raises the limit post. The linear module, the rotary cylinder and the extension cylinder cooperate with each other. After the auxiliary clamping top block abuts against the balance piece and the mechanical claw extends into the feeding groove, the clamping cylinder drives the mechanical claw to clamp the balance piece from both sides of the feeding groove, and under the cooperation of the extension cylinder and the rotary cylinder, the balance piece is taken away;

[0018] When the first proximity sensor detects that the balance piece leaves the feeding station, the first lifting cylinder raises the docking block, and the second lifting cylinder lowers the limit post. At the same time, the linear module, the rotary cylinder, the extension cylinder and the clamping cylinder cooperate with each other to place the balance piece in the positioning groove of the positioning block;

[0019] When the second proximity sensor detects that the balance piece is located in the positioning groove, the positioning cylinder pushes the positioning baffle to position the balance piece on the positioning block and waits for the next station device to take away the balance piece.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1) By arranging a docking block at the feeding station to form a feeding groove, the difficulty of grasping the thin balance piece by the mechanical claw is solved. At the same time, an auxiliary clamping top block is arranged inside the mechanical claw. After stabilizing the balance piece, the mechanical claw then grabs it, making the grabbing process convenient, stable and reliable. At the same time, a limit post is set to ensure that there is only one balance piece waiting to be fed at the feeding station, meeting the requirements of balance piece feeding;

[0022] 2) By arranging a plurality of inclined material storage slideways, the material storage function of the balance piece is conveniently realized. Only by installing rollers, the balance piece can enter the feeding station by its own gravity. The structure is simple. At the same time, by arranging a pressing plate mounting plate and a balance piece pressing plate, it is ensured that the balance piece slides smoothly in the material storage channel, improving the reliability of the device;

[0023] 3) By arranging multiple cylinders in the feeding mechanism, the actions of the feeding robotic arm and the mechanical claw are made flexible, ensuring accurate positioning when placing the balance sheet on the material-taking workbench. At the same time, a positioning baffle and a positioning cylinder are arranged on the material-taking workbench to reposition the balance sheet on the positioning block, realizing precise feeding of the balance sheet.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment

[0033] As Figure 1 , Figure 2 and Figure 3 shown, the present invention provides a balance sheet storage and feeding device, which includes a workbench bracket 2, a storage mechanism 3, a feeding mechanism 5, a picking workbench 4 respectively arranged on the workbench bracket 2, and a feeding robotic arm 6 arranged on the feeding mechanism 5. A workbench panel is placed on the workbench bracket 2, and a main frame 1 and a picking workbench 4 are fixed on the workbench panel. The feeding mechanism 5 is arranged on the workbench bracket 2 through the main frame 1. After the feeding robotic arm 6 grabs the balance sheet from the storage mechanism 3, it transports it to the picking workbench 4. The storage mechanism 3, the picking workbench 4, the feeding mechanism 5 and the feeding robotic arm 6 cooperate with each other.

[0034] As Figure 4 shown, the storage mechanism 3 includes a storage chute 310. There are rollers in the storage chute 310 and it is inclined. The lower end of the storage chute 310 is movably arranged on the workbench bracket 2 through a rotating mounting plate 302 and a mounting support seat 301, and the higher end is arranged on the workbench bracket 2 through a connecting block 312 and a jacking screw 313. The upper end of the jacking screw 313 is connected to the connecting block 312, and the lower end is threadedly connected to the workbench bracket 2, which can conveniently adjust the inclination angle of the storage chute 310. In this embodiment, the maximum inclination angle of the storage chute 310 is 30°. A feeding station is also provided at the lower end of the storage chute 310. Under the action of gravity and the rollers, the balance sheet moves towards the lower end of the storage chute 310 and slides into the feeding station.

[0035] The feeding station includes a blocking plate 305, a docking block 306, a limiting post 307 arranged in sequence from the top of the storage channel, a first jacking cylinder 303 connected to the docking block 306, and a second jacking cylinder 311 connected to the limiting post 307. The blocking plate 305 is used to prevent the balance sheet from sliding out of the storage chute 310. The first jacking cylinder 303 and the second jacking cylinder 311 are respectively arranged below the docking block 306 and the limiting post 307, and are fixedly installed on the rotating mounting plate 302 through a jacking cylinder mounting plate 304. The docking block 306 and the limiting post 307 can move up and down along the direction perpendicular to the storage chute 310 under the action of the first jacking cylinder 303 and the second jacking cylinder 311 respectively. When the limiting post 307 rises, a blocking protrusion is formed to prevent subsequent balance sheets from continuing to slide in, ensuring that there is only one balance sheet on the feeding station. When the docking block 306 descends, a feeding groove is formed to facilitate the feeding mechanism 5 to grab the balance sheet from both sides. When the balance sheet slides into the feeding station, the first proximity sensor 314 controls the first jacking cylinder 303 to lower the docking block 306 and controls the second cylinder to raise the limiting post 307; when the balance sheet leaves the feeding station, the first proximity sensor 314 controls the first jacking cylinder 303 to raise the docking block 306 and controls the second cylinder to lower the limiting post 307.

[0036] A plurality of sub-slides are arranged in parallel in the material storage slide 310, and a pressure plate mounting plate 309 is provided above the material storage slide 310. A balancing plate pressure plate 308 is installed on the pressure plate mounting plate 309 to prevent the sliding balancing plate from shifting the track due to mechanical vibration, thereby ensuring that the balancing plate slides stably into the feeding station.

[0037] like Figure 5 As shown, the feeding robot arm 6 is connected to the feeding mechanism 5 in a transmission manner. The feeding mechanism 5 includes a linear module 502, which is fixed to the main frame 1 through a linear module mounting plate 501. The feeding robot arm 6 includes a rotating cylinder 601, a feeding robot arm 504, a mechanical claw 607, an auxiliary clamping top block 606, an extension cylinder 603 and a clamping cylinder 605. The rotating cylinder 601 is linearly slidably arranged on the linear module 502 through a rotating cylinder connecting seat 503. The extension cylinder 603 is connected to the rotating cylinder 601 through a cylinder mounting seat 602 and rotates with the rotation cylinder 601. The clamping cylinder 605 is connected to the top of the extension cylinder 603 through a cylinder connecting block 604 to control the length of the feeding robot arm 504. The mechanical claw 607 and the auxiliary clamping top block 606 are all arranged at the bottom of the clamping cylinder 605, and the lower bottom surface of the auxiliary clamping top block 606 matches the shape of the balance sheet. The mechanical claw 607 is connected to the clamping cylinder 605 to grab the balance sheet of the feeding station. When grabbing the balance sheet, the mechanical claw 607 is controlled to be located above the feeding station by rotating the cylinder 601, and the mechanical claw 607 is lowered by extending the cylinder 603, so that the auxiliary clamping top block 606 is against the upper surface of the balance sheet to stabilize the balance sheet. At the same time, the mechanical claw 607 extends into the feeding groove and clamps both sides of the balance sheet through the clamping cylinder 605, and then lifts the grabbed balance sheet through the extension cylinder 603, and then uses the rotating cylinder 601 and the linear module 502 to transport the balance sheet to the vicinity of the material picking workbench 4, and prepares to position the balance sheet and place it on the material picking workbench 4.

[0038] like Figure 6 As shown, the material-retrieving workbench 4 includes a positioning mounting plate 401, positioning blocks 403, a positioning baffle 405 and a positioning cylinder 406 respectively installed on the positioning mounting plate 401, and a second proximity sensor 404 arranged on the positioning block 403. The positioning mounting plate 401 is fixed on the workbench panel through four positioning rods 402. When the mechanical claw 607 is located above the positioning block 403, the mechanical claw 607 is controlled to place the balance piece in the positioning groove on the positioning block 403. After the second proximity sensor 404 senses the balance piece, the positioning cylinder 406 pushes the positioning baffle 405 to position the balance piece in the positioning groove of the positioning block 403.

[0039] In this embodiment, the main frame 1 is made of an aluminum alloy main frame, and an organic protective glass is provided thereon to ensure safety and stability. The workbench support 2 is welded by carbon steel square tubes, with an exterior paint finish, and adjustable-height foot pads are installed on each foot to facilitate the adjustment of the horizontal height of the workbench.

[0040] The specific steps for the present invention to achieve material storage and feeding are as follows:

[0041] The balance weights are conveyed by the device of the previous working station to the storage slideway 310. The ten sub-slideways are provided for storing the balance weights. Since the storage slideway 310 has a certain angle and there are rollers in the storage slideway 310, and at the same time, under the action of the pressure plate mounting plate 309 and the balance weight pressure plate 308, the balance weights slide smoothly. Finally, the balance weights abut against the blocking plate 305, and the first proximity sensor 314 installed inside it receives the signal that the balance weights are in place, driving the second lifting cylinder 311 to control the lifting of the limit post 307 to block the subsequent balance weights from continuing to slide. At the same time, it drives the first lifting cylinder 303 to control the docking block 306 to descend, forming a feeding groove and waiting for the mechanical claw 607 to grab.

[0042] After the first proximity sensor 314 sends the signal that the balance weights are in place, the rotary cylinder 601 acts, driving the feeding robotic arm 504 to swing a certain angle and reach above the balance weights to be fed. Then, the extension cylinder 603 acts until the auxiliary clamping top block 606 abuts against the balance weights. The clamping cylinder 605 drives the mechanical claw 607 to grab the balance weights. Then, while the extension cylinder 603 acts, the rotary cylinder 601 returns to the original position, and the linear module 502 drives the feeding robotic arm 504 to move horizontally towards the picking workbench 4. At the same time, since the balance weights are taken away by the feeding robotic arm 504, the first proximity sensor 314 in the blocking plate 305 drives the first lifting cylinder 303 and the second lifting cylinder 311 to act, the docking block 306 rises, and the limit post 307 descends, and the balance weights continue to fall.

[0043] When the feeding mechanism 5 conveys the balance weights above the picking workbench 4, the extension cylinder 603 and the clamping cylinder 605 act to place the balance weights on the positioning block 403. After placing the balance weights, the feeding mechanism 5 returns to its original position and waits to enter the next cycle. The second proximity sensor 404 installed in the positioning block 403 receives the signal that the balance weights are in place, driving the positioning cylinder 406 to extend, driving the positioning baffle 405, and precisely positioning the balance weights on the positioning block 403, waiting for the feeding robotic arm of the next working station to take away the balance weights. Thus, a working cycle of storing and feeding a balance weight ends.

[0044] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any staff member familiar with the technical field of the present invention can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
