Description

Technical Field

[0001] The invention relates to the technical field of production and processing of low-frequency transformers, and in particular to an automatic feeding device for production and processing of low-frequency transformers. Background Art

[0002] A low-frequency transformer is an electronic device used primarily for voltage conversion and electrical isolation in circuits operating at low frequencies (usually in the human audio range, i.e. 20 Hz to 20 kHz). The most basic function of a low-frequency transformer is to change the magnitude of an AC voltage. It is typically used to convert the mains voltage to the lower voltage required by electronic equipment. It also provides electrical isolation, ensuring that there is no direct electrical connection between two parts of a circuit, thereby protecting the circuit and the user from electric shock. In some applications, low-frequency transformers are used to transfer power, such as in a power adapter to convert the mains power to the voltage and current required by the device.

[0003] In the processing and production of existing low-frequency transformers, the automatic feeding devices used are mostly single-channel designs. This design has certain limitations in flexibility and reliability. When facing mass production needs, the single-channel feeding system has only one feeding channel. When the vibration intensity of the vibration plate is too high, the transformer enters the channel at too fast a speed, which exceeds the processing capacity of the channel and causes blockage. At the same time, if multiple transformers enter the channel at the same time, it may also cause blockage. Once a blockage or equipment failure occurs, the operation of the entire production line will be affected, resulting in reduced production efficiency and increased costs. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that most automatic feeding devices are of single-channel design and if blocked, the production line will be affected, and an automatic feeding device for low-frequency transformer production and processing is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic feeding device for low-frequency transformer production and processing, comprising a vibration plate body, the inner surface of which is fixedly provided with a spiral channel, characterized in that a shunt mechanism capable of automatically feeding the low-frequency transformer is mounted on the vibration plate body;

[0007] The shunting mechanism includes a first feeding rack and a second feeding rack used in conjunction with the vibration plate body, an electric gate is provided at the outlet end of the spiral channel, a guide component capable of shunting the low-frequency transformer to prevent the low-frequency transformer from being blocked during feeding is also provided at the outlet end of the spiral channel, and a pushing component capable of assisting the low-frequency transformer in feeding is also provided at the outlet end of the spiral channel;

[0008] It also includes a protection mechanism which is mounted on the outer surface of the spiral channel to guide the fallen low-frequency transformer.

[0009] As a further description of the above technical solution:

[0010] The guide assembly includes a first motor fixedly mounted at the bottom of the spiral channel outlet end, a first rotating shaft is rotatably mounted on one side of the first feeding rack, and a guide plate is fixedly mounted on the surface of the first rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The first rotating shaft is fixedly mounted on the output end of the first motor, the outlet end surface of the spiral channel is set as an inclined surface, and the inclined surface is located between the first feed rack and the second feed rack. Sensors are set on the top of the vibration plate body and the first feed rack and the second feed rack.

[0013] As a further description of the above technical solution:

[0014] The pushing assembly includes an annular frame fixedly installed on one side of the outlet end of the spiral channel, an I-shaped frame is symmetrically installed on the top of the annular frame, a second motor is fixedly installed on the bottom of the outlet port of the spiral channel, a second rotating shaft is fixedly installed on the output end of the second motor, an L-shaped plate and a long plate are fixedly installed on the outer surface of the second rotating shaft, a groove is opened inside the outlet end of the spiral channel, and limiting plates are symmetrically inserted inside the groove, the bottom end of each limiting plate is fixedly connected to an extension plate, and the surface of the extension plate is sleeved with a first spring.

[0015] As a further description of the above technical solution:

[0016] The two groups of I-shaped frames are fixedly mounted on the long board, both sides of the top of the L-shaped board are arranged in arc shape, and the bottom end of the extension board passes through the groove and extends to the outside of the spiral channel.

[0017] As a further description of the above technical solution:

[0018] The protective mechanism includes a spiral frame fixedly installed on one side of the outer surface of the spiral channel, paddles are fixedly installed on both sides of the inner surface of the vibration plate body, the outlet end of the spiral frame is rotatably connected to a discharge plate, an L-shaped frame is fixedly installed at the bottom of the outlet end of the spiral frame, and a second spring is arranged between the L-shaped frame and the discharge plate.

[0019] As a further description of the above technical solution:

[0020] The paddle is arc-shaped, the blanking plate is tilted downward, the second spring is fixedly mounted on the L-shaped frame, and the top end of the second spring is in contact with the bottom end of the blanking plate.

[0021] As a further description of the above technical solution:

[0022] There is a height difference between the outlet end of the spiral frame and the bottom end of the inner surface of the vibration plate body, and the middle part of the inner surface of the vibration plate body is configured to be conical.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. By providing a shunt mechanism, in the initial state, the guide plate is in an open state to block the first feed rack and the second feed rack, so that the low-frequency transformer can only enter the first feed rack for transportation. If the low-frequency transformer in the first feed rack is blocked, the first motor and the electric gate are operated through the sensor, so that the electric gate rises to block the low-frequency transformer being transported. At the same time, the first motor drives the first shaft to drive the guide plate to rotate toward the inside of the first feed rack, close the first feed rack, and transport the low-frequency transformer to the inside of the second feed rack to prevent the low-frequency transformer from being blocked and affecting the speed of the production line. At the same time, the first motor can also drive the guide plate to rotate toward the direction of the second feed rack, so that the first feed rack and the second feed rack are opened at the same time, forming a dual channel for loading, further improving the loading rate and improving the usage scenario.

[0025] 2. By providing a pushing component, when the low-frequency transformer is fed through the spiral channel, when the low-frequency transformer moves to the first feed rack or the second feed rack, the second rotating shaft is driven to rotate by the second motor, so that the long plate rotates toward the first feed rack or the second feed rack, and the long plate will also drive the I-shaped frame to rotate in the corresponding direction while rotating, and the I-shaped frame extends from the corresponding annular frame opening, contacts with the low-frequency transformer and pushes the low-frequency transformer, assisting the low-frequency transformer in feeding, and repeating the cycle. If the first feed rack and the second feed rack are opened at the same time, the long plate reciprocates toward the first feed rack and the second feed rack to prevent the low-frequency transformer from piling up at the inlet end of the first feed rack and the second feed rack.

[0026] 3. When the second rotating shaft rotates, it will also drive the L-shaped plate to rotate, so that the L-shaped plate rotates with the long plate. After the L-shaped plate rotates, the arc surface at one end of its top contacts the corresponding extension plate, and the extension plate is squeezed by the curvature of the arc surface, so that the extension plate drives the limit plate to rise. When the I-shaped frame pushes the low-frequency transformer, the extension plate is located at the highest point of the arc surface on the L-shaped plate, and the rising limit plate is located between the two low-frequency transformers to play a limiting role, so that the I-shaped frame will only contact and push one low-frequency transformer at a time, preventing the two low-frequency transformers from squeezing and fitting each other, and causing blockage at the feed port of the first feed rack or the second feed rack due to pushing.

[0027] 4. By providing a protective mechanism, when the low-frequency transformer is loaded through the spiral channel, the vibration of the vibration disk body will cause the low-frequency transformers to stack on each other. Therefore, during loading, the stacked low-frequency transformers will fall into the spiral rack through vibration and the blocking of the paddles, and will be discharged from the blanking plate into the vibration disk body through the rotation of the spiral rack, preventing the low-frequency transformer from falling directly and colliding with the vibration disk body. When the low-frequency transformer is unloaded through the blanking plate, the blanking plate will be squeezed as the low-frequency transformer moves on the blanking plate, causing the blanking plate to rotate downward to reduce the height between the blanking plate and the vibration disk body, thereby preventing the low-frequency transformer from being damaged due to collision.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 - Fig. 9 As shown, the present invention provides: an automatic feeding device for low-frequency transformer production and processing, comprising a vibration plate body 10, a spiral channel 11 is fixedly installed on the inner surface of the vibration plate body 10, and a shunt mechanism 20 capable of automatically feeding the low-frequency transformer is provided on the vibration plate body 10;

[0043] The shunting mechanism 20 includes a first feeding rack 21 and a second feeding rack 22 used in conjunction with the vibration plate body 10. An electric gate 23 is provided at the outlet end of the spiral channel 11. The outlet end of the spiral channel 11 is also equipped with a guide component 24 that can shunt the low-frequency transformer to prevent the low-frequency transformer from being blocked during feeding. The outlet end of the spiral channel 11 is also equipped with a push component 25 that can assist the low-frequency transformer in feeding.

[0044] It also includes a protection mechanism 30 mounted on the outer surface of the spiral channel 11 to guide the fallen low-frequency transformer.

[0045] In further detail, the guide assembly 24 includes a first motor 241 fixedly mounted at the bottom of the outlet end of the spiral channel 11, a first rotating shaft 242 is rotatably mounted on one side of the first feed rack 21, a guide plate 243 is fixedly mounted on the surface of the first rotating shaft 242, and the first rotating shaft 242 is driven to rotate by the first motor 241, so that the rotating first rotating shaft 242 synchronously drives the guide plate 243 to rotate;

[0046] In the initial state, the guide plate 243 is in an open state to block the first feed rack 21 and the second feed rack 22, so that the low-frequency transformer can only enter the first feed rack 21 for transportation. At this time, the second motor 253 is operated through the sensor 26. At this time, the second motor 253 drives the second shaft 254 to rotate, so that the long plate 256 rotates toward the direction of the first feed rack 21. While rotating, the long plate 256 also drives the I-shaped frame 252 to rotate in the corresponding direction, so that the I-shaped frame 252 extends from the corresponding opening of the annular frame 251, contacts the low-frequency transformer and plays a role of pushing the low-frequency transformer;

[0047] If the low-frequency transformer in the first feed rack 21 is blocked, the electric gate 23 and the first motor 241 are operated through the sensor 26, so that the electric gate 23 rises to block the low-frequency transformer being transported. At the same time, the first motor 241 drives the first rotating shaft 242 to drive the guide plate 243 to rotate toward the inside of the first feed rack 21, and the first feed rack 21 is closed. Then the electric gate 23 descends to transport the low-frequency transformer toward the inside of the second feed rack 22 to prevent the low-frequency transformer from being blocked and affecting the production line. At this time, the long plate 256 will drive the I-shaped frame 252 to extend from the opening corresponding to the annular frame 251 and the second feed rack 22 for reciprocating pushing.

[0048] In further detail, the first rotating shaft 242 is fixedly mounted on the output end of the first motor 241, and the outlet end surface of the spiral channel 11 is set as an inclined surface. When the feeding to the second feeding rack 22 is stopped, due to the obstruction of the electric gate 23, a number of low-frequency transformers will be located at the channel at the feeding port of the second feeding rack 22. The setting of the inclined surface enables a number of low-frequency transformers to slide downward, so that a number of low-frequency transformers will also move toward the feeding port of the second feeding rack 22. At the same time, auxiliary feeding is performed by the pushing component 25 to prevent a number of low-frequency transformers from piling up in the channel. This inclined surface is located between the first feeding rack 21 and the second feeding rack 22. Sensors 26 are provided at the tops of the vibration plate body 10 and the first feeding rack 21 and the second feeding rack 22. The electric signal emitted by the sensor 26 drives the electric gate 23, the first motor 241 and the second motor 253 to operate;

[0049] At the same time, the first motor 241 can also drive the guide plate 243 to rotate toward the direction of the second feed rack 22, so that the first feed rack 21 and the second feed rack 22 are opened at the same time, forming a dual channel for loading, further improving the loading rate and improving the usage scenario. At this time, the I-shaped frame 252 reciprocates at the two openings of the annular frame 251 through the long plate 256 to play a pushing role.

[0050] like Figure 6 - Figure 7 As shown, the pushing assembly 25 includes an annular frame 251 fixedly mounted on one side of the outlet end of the spiral channel 11, an I-shaped frame 252 is symmetrically mounted on the top of the annular frame 251, a second motor 253 is fixedly mounted on the bottom of the outlet port of the spiral channel 11, a second rotating shaft 254 is fixedly mounted on the output end of the second motor 253, an L-shaped plate 255 and a long plate 256 are fixedly mounted on the outer surface of the second rotating shaft 254, a groove 257 is opened inside the outlet end of the spiral channel 11, and a limiting plate 258 is symmetrically inserted inside the groove 257, and the bottom end of each limiting plate 258 is fixedly connected to an extension plate 259, and the surface of the extension plate 259 is sleeved with a first spring 2510, and the first spring 2510 is fixedly connected to the groove 257 and the limiting plate 258.

[0051] In further detail, the two sets of I-shaped frames 252 are fixedly mounted on the long plate 256, the top sides of the L-shaped plate 255 are both set to arc shapes, and the bottom end of the extension plate 259 passes through the groove 257 and extends to the outside of the spiral channel 11;

[0052] When the second rotating shaft 254 rotates, it will also drive the L-shaped plate 255 to rotate, so that the L-shaped plate 255 rotates along with the long plate 256. After the L-shaped plate 255 rotates, the arc surface at one end of the top of the L-shaped plate 255 contacts the corresponding extension plate 259, and the extension plate 259 is squeezed by the curvature of the arc surface, so that the extension plate 259 drives the limit plate 258 to rise. When the I-shaped frame 252 pushes the low-frequency transformer, the extension plate 259 is located at the highest point of the arc surface on the L-shaped plate 255, and the rising limit plate 258 is located between the two low-frequency transformers to play a limiting role, so that the I-shaped frame 252 will only contact and push one low-frequency transformer at a time, so as to prevent the two low-frequency transformers from being squeezed and fitted with each other, and the feeding port of the first feeding frame 21 or the second feeding frame 22 will be blocked by pushing;

[0053] When the pushing is completed, the L-shaped plate 255 and the long plate 256 are rotated synchronously through the second rotating shaft 254. At this time, the long plate 256 drives the I-shaped frame 252 back to the annular frame 251, and the arc surface on one side of the L-shaped plate 255 will no longer contact the extension plate 259. At this time, the extension plate 259 and the limit plate 258 are reset by their own gravity and the reaction force of the first spring 2510, and no longer play a limiting role.

[0054] like Figure 8 - Fig. 9 As shown, the protection mechanism 30 includes a spiral frame 301 fixedly mounted on one side of the outer surface of the spiral channel 11, paddles 302 are fixedly mounted on both sides of the inner surface of the vibration plate body 10, the outlet end of the spiral frame 301 is rotatably connected to a blanking plate 303, an L-shaped frame 304 is fixedly mounted on the bottom of the outlet end of the spiral frame 301, and a second spring 305 is arranged between the L-shaped frame 304 and the blanking plate 303;

[0055] When the low-frequency transformers are loaded through the spiral channel 11, the vibration of the vibration disk body 10 will cause the low-frequency transformers to be stacked on each other. Therefore, during loading, the stacked low-frequency transformers will fall into the spiral rack 301 through vibration and the blocking of the paddle 302. The spiral rack 301 is rotated and discharged from the unloading plate 303 into the interior of the vibration disk body 10, preventing the low-frequency transformer from falling directly and colliding with the vibration disk body 10.

[0056] In further detail, the paddle 302 is arc-shaped, the blanking plate 303 is tilted downward, the second spring 305 is fixedly mounted on the L-shaped frame 304 , and the top end of the second spring 305 is in contact with the bottom end of the blanking plate 303 .

[0057] In further detail, there is a height difference between the outlet end of the spiral frame 301 and the bottom end of the inner surface of the vibration disk body 10. The middle part of the inner surface of the vibration disk body 10 is set to be cone-shaped. When the low-frequency transformer is unloaded through the unloading plate 303, as the low-frequency transformer moves on the unloading plate 303, the unloading plate 303 will also be squeezed, so that the unloading plate 303 rotates downward to reduce the height between the unloading plate 303 and the vibration disk body 10, thereby preventing the low-frequency transformer from being damaged due to collision.

[0058] Working principle: In the initial state, the guide plate 243 is in an open state to block the first feed rack 21 and the second feed rack 22, so that the low-frequency transformer can only enter the first feed rack 21 for transportation. At this time, the second motor 253 is operated through the sensor 26. At this time, the second motor 253 drives the second shaft 254 to rotate, so that the long plate 256 rotates toward the direction of the first feed rack 21. While the long plate 256 rotates, it also drives the I-shaped frame 252 to rotate in the corresponding direction, so that the I-shaped frame 252 extends from the corresponding opening of the annular frame 251, contacts the low-frequency transformer and plays a role of pushing the low-frequency transformer;

[0059] If the low-frequency transformer in the first feed rack 21 is blocked, the electric gate 23 and the first motor 241 are operated through the sensor 26, so that the electric gate 23 rises to block the low-frequency transformer being transported, and at the same time, the first motor 241 drives the first rotating shaft 242 to drive the guide plate 243 to rotate toward the inside of the first feed rack 21, and the first feed rack 21 is closed. Then the electric gate 23 descends to transport the low-frequency transformer to the inside of the second feed rack 22, so as to prevent the low-frequency transformer from being blocked and affecting the production line. At this time, the long plate 256 will drive the I-shaped frame 252 to extend from the opening corresponding to the annular frame 251 and the second feed rack 22, and push it back and forth;

[0060] At the same time, the first motor 241 can also drive the guide plate 243 to rotate in the direction of the second feed rack 22, so that the first feed rack 21 and the second feed rack 22 are opened at the same time, forming a double channel for loading, further improving the loading rate and improving the usage scenario. At this time, the I-shaped frame 252 reciprocates at the two openings of the annular frame 251 through the long plate 256 to play a pushing role;

[0061] When the second rotating shaft 254 rotates, it will also drive the L-shaped plate 255 to rotate, so that the L-shaped plate 255 rotates along with the long plate 256. After the L-shaped plate 255 rotates, the arc surface at one end of the top of the L-shaped plate 255 contacts the corresponding extension plate 259, and the extension plate 259 is squeezed by the curvature of the arc surface, so that the extension plate 259 drives the limit plate 258 to rise. When the I-shaped frame 252 pushes the low-frequency transformer, the extension plate 259 is located at the highest point of the arc surface on the L-shaped plate 255, and the rising limit plate 258 is located between the two low-frequency transformers to play a limiting role, so that the I-shaped frame 252 will only contact and push one low-frequency transformer at a time, so as to prevent the two low-frequency transformers from being squeezed and fitted with each other, and the feeding port of the first feeding frame 21 or the second feeding frame 22 will be blocked by pushing;

[0062] When the low-frequency transformers are loaded through the spiral channel 11, the vibration of the vibration plate body 10 will cause the low-frequency transformers to be stacked on each other. Therefore, during loading, the stacked low-frequency transformers will fall into the spiral rack 301 through vibration and the blocking of the paddle 302. The spiral rack 301 is rotated and discharged from the unloading plate 303 into the vibration plate body 10, preventing the low-frequency transformers from falling directly and colliding with the vibration plate body 10.

[0063] When the low-frequency transformer is unloaded through the unloading plate 303, as the low-frequency transformer moves on the unloading plate 303, the unloading plate 303 will be squeezed, causing the unloading plate 303 to rotate downward to reduce the height between it and the vibration disk body 10, thereby preventing the low-frequency transformer from being damaged due to collision.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
