Description

Technical Field

[0001] This utility model belongs to the technical field of needle-type current transformer columnar device, specifically relating to an automatic assembly device for a current transformer and a conductive rod. Background Technology

[0002] A pin-type current transformer converts a large current in a high-current circuit into a smaller current, typically a standard current of 5A or 1A. For example, for a pin-type current transformer with a nominal ratio of 500 / 5, when the primary side (high-voltage side) current is 500 amperes (A), the secondary side (low-voltage side) current is 5 amperes (A). This allows for convenient measurement using a standard ammeter, ensuring the measuring instrument operates within a safe current range and enabling accurate current measurement. This provides accurate data for power system load management, fault diagnosis, and energy metering.

[0003] like Figure 1 The diagram shows a pin-type current transformer 4, which includes a transformer 4 with a socket 5 into which one or two conductive rods 1 can be inserted. In current manufacturing processes, the pin-type current transformer 4 is primarily installed manually. Because the conductive rods 1 are small and U-shaped, and the socket 5 of the transformer 4 is also small, this process is very labor-intensive. In particular, prolonged focus on aligning the conductive rods 1 with the socket 5 can easily cause visual fatigue and may damage the operator's eyesight. Furthermore, a certain amount of force is required to correctly insert the conductive rods 1 into the socket 5 of the transformer 4, meaning that purely manual operation or operation with the aid of hard tools may cause hand injuries. Besides the potential injury to workers, problems such as insufficient insertion force, incorrect orientation, and the conductive rods 1 scratching the transformer 4 may occur. These problems not only reduce work efficiency but also affect the yield rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic assembly device for current transformers and conductive rods, in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: An automatic assembly device for a current transformer and a conductive rod is proposed.

[0026] The first material picking block is connected to the output end of the fifth drive unit and movably mounted on the second support frame. The first material picking block is provided with a first material conveying trough, which is used to receive and transport the conductive rod on the conductive rod conveying track.

[0027] In the aforementioned automatic assembly device for current transformers and conductive rods, the conductive rod dispensing mechanism further includes a vacuum generator. The vacuum generator is mounted on the frame. A gas channel is provided through the first material receiving block. One end of the gas channel is connected to the first material conveying trough, and the other end is provided with a gas pipe connector. The gas pipe connector is connected to the vacuum generator through a pipe to fix the conductive rod in the first material conveying trough.

[0028] In the aforementioned automatic assembly device for current transformers and conductive rods, the current transformer transport unit includes a current transformer transport track, and the discharge end of the current transformer transport track is provided with a current transformer sorting mechanism.

[0029] In the aforementioned automatic assembly device for current transformers and conductive rods, the current transformer dispensing mechanism includes:

[0030] The third support frame is mounted on the frame;

[0031] A sixth driving component is connected to the third support frame, and the direction of movement of the output end of the sixth driving component is perpendicular to the feeding direction of the current transformer conveying track.

[0032] The second material taking block is connected to the output end of the sixth drive unit and is movably mounted on the third support frame.

[0056] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0057] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0058] like Figures 2 to 10 As shown, an automatic assembly device for current transformers and conductive rods according to this solution includes: a frame 100, a conductive rod transport unit 200, a current transformer transport unit 300, and an assembly unit 400.

[0059] In this design, the current transformer 4 is provided with a socket 5 for inserting a conductive rod 1. The conductive rod 1 consists of a central crossbar 2 and two extension rods 3 extending outwards at a certain angle at both ends. Normally, the crossbar 2 is perpendicular to the two extension rods 3, and the two extension rods 3 are parallel to each other. When the conductive rod 1 is inserted into the socket 5, the crossbar 2 is located inside the socket 5, while the two extension rods 3 are located outside the current transformer 4.

[0060] The conductive rod transport unit 200, the current transformer transport unit 300, and the assembly unit 400 are all mounted on the frame 100. Preferably, the conductive rod transport unit 200 and the current transformer transport unit 300 are arranged parallel to each other on the frame 100, while the assembly unit 400 is located between them. The conductive rod transport unit 200 is responsible for transporting the conductive rod 1 to be assembled to the designated position and is equipped with a conductive rod vibratory feeder 230 to ensure that the conductive rod 1 is arranged in a predetermined direction and transported onto the conductive rod transport unit 200. Similarly, the current transformer transport unit 300 is also equipped with a current transformer vibratory feeder 330 to ensure that the current transformer 4 is transported onto the current transformer transport unit 300 in a set direction. Since the working principle of the vibratory feeder is common knowledge in the industry, its specific structure will not be described in detail here.

[0061] The assembly unit 400 is movably equipped with a conductive rod gripper 410. The main function of the conductive rod gripper 410 is to grip the conductive rod 1 from the conductive rod transport unit 200 and accurately assemble it into the socket 5 of the current transformer 4. In order to complete the assembly between the conductive rod 1 and the current transformer 4, the movement of the conductive rod gripper 410 is divided into two parts: gripping stroke and insertion stroke.

[0062] During the gripping stroke, the conductive rod gripper 410 lifts the conductive rod 1 above the current transformer 4 and adjusts the position of the conductive rod 1 so that the axis of its crossbar 2 forms an angle with the axis of the socket 5, in order to simulate the process of manually inserting the conductive rod 1 into the socket 5 at an angle. During the insertion stroke, the extension rod 3 (i.e., the lower extension rod 3) of the conductive rod 1 near the current transformer 4 is pushed into the socket 5 by the conductive rod gripper 410 and drives the conductive rod 1 to rotate relative to the current transformer 4, thereby passing through the socket 5 and realizing the successful assembly of the conductive rod 1 and the current transformer 4.

[0063] Preferably, the conductive rod gripper 410 is a pneumatic gripper, which includes a bidirectional cylinder and two clamping blocks connected to the output end of the bidirectional cylinder. The bidirectional cylinder drives the two clamping blocks to move closer to each other, thereby realizing the clamping and releasing operation of the conductive rod gripper 410.

[0064] In a further preferred embodiment, this solution also includes a control unit electrically connected to the conductive rod transport unit 200, the transformer transport unit 300, and the assembly unit 400, which is used to realize the automated operation of the entire automatic assembly device.

[0065] This solution automates the conveying process of the conductive rod 1 and the current transformer 4, and simulates manual assembly, thereby achieving automatic assembly of the needle-type current transformer 4. This improves assembly efficiency, reduces manpower requirements in the production process, and enhances the quality of product assembly.

[0066] In this scheme, the insertion stroke includes a moving section and a rotating section. When in the moving section, the conductive rod 1 can move laterally towards the current transformer 4 under the action of the conductive rod clamp 410, so that the extension rod 3 on the side of the conductive rod 1 close to the current transformer 4 can be inserted into the current transformer 4. When in the rotating section, the extension rod 3 inserted into the current transformer 4 on the conductive rod 1 can pass through the insertion hole 5.

[0067] When the assembly unit 400 moves the conductive rod gripper 410 towards the transformer transport unit 300, positioning the conductive rod 1 above the transformer 4, the lower extension rod 3 of the conductive rod 1 will insert into the insertion hole 5 of the transformer 4 during the insertion stroke. As the conductive rod 1... Figure 3 As shown, during the downward tilting movement, since the conductive rod 1 is tilted towards the current transformer 4, the right side of the lower extension rod 3 of the conductive rod 1 may gradually approach the right side wall of the current transformer 4 socket 5, and may even come into contact or collide. This may cause the conductive rod 1 to impact the current transformer 4, causing damage to the appearance of the current transformer 4.

[0068] To avoid this situation, during the downward movement of the conductive rod 1, the assembly unit 400 controls the conductive rod gripper 410 to perform lateral displacement, that is, along... Figure 3 The movement is from right to left as shown. This process ensures that the conductive rod gripper 410 can lower the conductive rod 1 while preventing unnecessary contact between the conductive rod 1 and the current transformer 4, thereby protecting the current transformer 4 from damage.

[0069] In this way, the assembly unit 400 not only achieves the precise insertion of the conductive rod 1, but also effectively avoids physical damage to the current transformer 4 that may be caused during the assembly process.

[0070] Reference Figures 2 to 4 The assembly unit 400 includes: a first support frame 420; a first drive member 430 disposed on the first support frame 420 along its length; a second drive member 440 connected to the output end of the first drive member 430 along its width, the first drive member 430 driving the second drive member 440 to move along the length of the first support frame 420; a third drive member 450 connected to the output end of the second drive member 440 along its height, the second drive member 440 driving the third drive member 450 to move along the width of the first support frame 420; a fourth drive member 460 connected to the output end of the third drive member 450, the third drive member 450 driving the fourth drive member 460 to move along the height of the first support frame 420; and a conductive rod gripper 410 connected to the output end of the fourth drive member 460 to rotate the conductive rod gripper 410.

[0071] The first support frame 420 is fixed to the frame 100 by threaded connection or welding, providing support for the entire assembly unit 400. The first drive component 430, the second drive component 440, and the third drive component 450 are preferably in the form of linear guide rails; of course, in addition to linear guide rails, these drive components can also be other types of actuators such as cylinders or hydraulic cylinders. These three drive components are respectively arranged along the length, width, and height directions of the first support frame 420, and are used to realize the forward, backward, left, right, and up-down movement of the conductive rod 1 in three-dimensional space, thereby completing the transmission of the conductive rod 1 from the conductive rod transport unit 200 to the current transformer transport unit 300.

[0072] The fourth driving component 460 preferably uses a stepper motor, which drives the conductive rod 1 to rotate by rotating the conductive rod gripper 410. When the conductive rod 1 moves from the conductive rod transport unit 200 to the current transformer transport unit 300, this rotation ensures that the axis of the conductive rod 1 can form a specific angle with the axis of the current transformer 4 socket 5. At the same time, it also enables the conductive rod gripper 410 to rotate appropriately during the insertion process to ensure accurate docking.

[0073] During the rotation segment of the insertion stroke, when the conductive rod gripper 410 drives the conductive rod 1 to rotate, causing the extension rod 3 at the lower end of the conductive rod 1 to pass through the insertion hole 5 of the current transformer 4, due to possible machining errors during manufacturing (e.g., the extension rods 3 at both ends of the conductive rod 1 are not perpendicular to the crossbar 2, or the insertion hole 5 of the current transformer 4 is too small), the conductive rod 1 may rub against the current transformer 4 as it rotates with the conductive rod gripper 410. If this rubbing force is too large, it may scratch the surface of the current transformer 4, resulting in an indentation. To solve this problem, in this solution, a torque sensor 470 is installed between the fourth drive member 460 and the conductive rod gripper 410, and this sensor is electrically connected to the fourth drive member 460.

[0074] When the conductive rod 1 begins to contact the current transformer 4, the torque transmitted from the current transformer 4 to the torque sensor 470 via the conductive rod gripper 410 is detected. At this time, the torque sensor 470 triggers the fourth drive unit 460 to adjust the angle of the conductive rod gripper 410, causing it to deviate from the originally preset rotation angle, thereby allowing the conductive rod 1 to rotate further and pass through the socket 5 of the current transformer 4. Because the torque sensor 470 has high sensitivity, it can detect the contact between the conductive rod 1 and the current transformer 4 as soon as they begin to make contact and respond quickly, allowing them to separate even under a small contact force, thus preventing damage to the surface of the current transformer 4.

[0075] Reference Figure 1 , Figure 2 , Figure 3 ,and Figure 5In this scheme, the conductive rod conveying unit 200 includes a conductive rod conveying track 210, and a conductive rod dispensing mechanism 220 is provided at the discharge end of the conductive rod conveying track 210. The conductive rods 1 are closely arranged on the conductive rod conveying track 210, and the conductive rod dispensing mechanism 220 is used to convey the conductive rods 1 individually.

[0076] The conductive rod conveying track 210 preferably uses a linear vibrator. A linear vibrator is a mechanical device that generates periodic vibrations in a linear direction, suitable for conveying conductive rods 1. The feed end of the conductive rod conveying track 210 is connected to the discharge end of the conductive rod vibrating plate 230, receiving the neatly arranged conductive rods 1 from the vibrating plate 230. The conductive rod conveying track 210 is responsible for secondary conveying of the conductive rods 1, ensuring their close arrangement while moving them towards the conductive rod distribution mechanism 220. The conductive rod distribution mechanism 220 delivers the closely arranged conductive rods 1 one by one to the position where the conductive rod gripper 410 can grasp them, thereby achieving automated feeding of the conductive rods 1.

[0077] To better control the process, the preferred conductive rod conveying unit 200 also includes a sensor disposed on one side of the conductive rod conveying track 210, which is electrically connected to the conductive rod vibratory feeder 230. Since the conveying speed of the conductive rod vibratory feeder 230 is relatively high, and the dispensing speed of the conductive rod dispensing mechanism 220 may not be perfectly matched, the sensor disposed here can monitor the number of conductive rods 1 on the conductive rod conveying track 210 in real time. When the number of conductive rods 1 exceeds a preset value, the sensor triggers a signal to stop the conductive rod vibratory feeder 230, ensuring the normal operation of the conductive rod conveying unit 200.

[0078] Reference Figure 6 , Figure 7 , Figure 8 The conductive rod feeding mechanism 220 includes: a second support frame 221, which is disposed on the frame 100; a fifth driving member 222, which is connected to the second support frame 221, and the moving direction of the output end of the fifth driving member 222 is perpendicular to the feeding direction of the conductive rod conveying track 210; and a first picking block 223, which is connected to the output end of the fifth driving member 222 and movably disposed on the second support frame 221. The first picking block 223 is provided with a first conveying trough 223a, which is used to receive and convey the conductive rod 1 on the conductive rod conveying track 210.

[0079] The second support frame 221 is fixed to the frame 100 by threaded connection or welding, providing support for the entire conductive rod dispensing mechanism 220. The fifth drive unit 222 is preferably a cylinder, but it can also be a motor, hydraulic cylinder, or other type of drive. The first picking block 223 is equipped with a sensor electrically connected to the fifth drive unit 222, and the sensing end of the sensor faces the first conveying trough 223a. During operation, the fifth drive unit 222 pushes the first picking block 223, aligning the first conveying trough 223a on it with the discharge end of the conductive rod conveying track 210. When the sensor detects that the first conveying trough 223a has received the conductive rod 1 from the conductive rod conveying track 210, the fifth driving member 222 is activated, driving the first picking block 223 to move, thereby separating the conductive rod 1 in the first conveying trough 223a from the other conductive rods 1 on the conductive rod conveying track 210, and transporting the conductive rod 1 to a position that the conductive rod gripper 410 can grasp, so that the conductive rod gripper 410 can grasp the conductive rod 1 in the first conveying trough 223a.

[0080] In this scheme, the conductive rod dispensing mechanism 220 also includes a vacuum generator 224, which is mounted on the frame 100. The first material receiving block 223 is provided with a gas channel 223b that passes through the first material receiving block 223. One end of the gas channel 223b is connected to the first material conveying trough 223a, and the other end is provided with a gas pipe connector 225. The gas pipe connector 225 is connected to the vacuum generator 224 through a pipe to fix the conductive rod 1 in the first material conveying trough 223a.

[0081] When the sensor detects that the conductive rod 1 is already in the first conveying trough 223a, the vacuum generator 224 is activated. By extracting air from the gas channel 223b, a negative pressure is created in the gas channel 223b, generating an adsorption force that firmly adsorbs the conductive rod 1 into the first conveying trough 223a. This ensures that the conductive rod 1 remains stable when moving under the action of the fifth driving member 222, so that the subsequent conductive rod gripper 410 can accurately grasp the conductive rod 1.

[0082] Reference Figure 2 , Figure 3 and Figure 9 The current transformer conveying unit 300 includes a current transformer conveying track 310. The discharge end of the current transformer conveying track 310 is provided with a current transformer distributing mechanism 320. The current transformers 4 are closely arranged on the current transformer conveying track 310. The current transformer distributing mechanism 320 is used to convey the current transformers 4 individually.

[0083] The feed end of the current transformer transport track 310 is connected to the discharge end of the current transformer vibratory feeder 330, receiving the current transformers 4 that are already arranged neatly from the current transformer vibratory feeder 330. In a preferred embodiment, the discharge end of the current transformer transport track 310 is equipped with a sensor electrically connected to the current transformer distribution mechanism 320. During operation, when the sensor detects that the current transformer 4 has been transported to the discharge end of the current transformer transport track 310, the current transformer distribution mechanism 320 sends the current transformers 4 one by one to a predetermined position, thereby facilitating the insertion of the conductive rod 1 into the current transformer 4 by the conductive rod gripper 410.

[0084] Reference Figure 2 , Figure 3 , Figure 9 and Figure 10 The current transformer feeding mechanism 320 includes: a third support frame 321, which is mounted on the frame 100; a sixth drive member 322, which is connected to the third support frame 321, and the movement direction of the output end of the sixth drive member 322 is perpendicular to the feeding direction of the current transformer conveying track 310; a second picking block 323, which is connected to the output end of the sixth drive member 322 and movably mounted on the third support frame 321, and the second picking block 323 is provided with a second conveying trough 323a, which is used to receive and transport the current transformers 4 on the current transformer conveying track 310; and a seventh drive member 324, which is mounted on the frame 100 and is positioned opposite to the sixth drive member 322, and the seventh drive member 324 is provided with a blocking block 325, which movably abuts against the current transformer 4 in the second conveying trough 323a to provide a limit for the current transformer 4.

[0085] The third support frame 321 is used to install and fix the entire current transformer feeding mechanism 320 onto the frame 100. Preferably, the third support frame 321 and the frame 100 can be fixed by threaded connection or welding. The sixth drive component 322 and the seventh drive component are preferably cylinders, but other types of drives such as motors or hydraulic cylinders can also be used. A sensor is provided on the second picking block 323, which faces the second conveying trough 323a and is electrically connected to the sixth drive component 322. When the current transformer conveying track 310 transports the current transformer 4 to the second conveying trough 323a and is detected by the sensor, the sixth drive component 322 drives the second picking block 323 to move, separating the current transformer 4 in the second conveying trough 323a from the other current transformers 4 on the current transformer conveying track 310 and transporting it to a predetermined position. After the current transformer 4 is delivered to its position, the seventh drive unit moves the blocking block 325 to the opening of the second conveying trough 323a, providing a limit to the current transformer 4 in the second conveying trough 323a, ensuring that the current transformer 4 remains fixed when the conductive rod clamp 410 inserts the conductive rod 1 into the current transformer 4, thereby ensuring the normal installation of the current transformer 4 and the conductive rod 1.

[0086] Reference Figure 10The second material taking block 323 is provided with a clearance groove 323b that communicates with the second material conveying trough 323a. When in the insertion stroke, the clearance groove 323b is used to provide clearance for the extension rod 3 to pass through the insertion hole 5.

[0087] When the conductive rod clamp 410 drives the conductive rod 1 to rotate, and the extension rod 3 below the conductive rod 1 passes through the insertion hole 5 on the current transformer 4, the clearance groove 323b provides sufficient space for the extension rod 3 to pass through, ensuring normal insertion between the conductive rod 1 and the current transformer 4.

[0088] This solution also includes a feeding unit 500, which is used to remove the current transformer 4 assembled with the conductive rod 1 from the second conveying trough 323a. The feeding unit 500 includes: an eighth driving member 510, which is connected to the third support frame 321, and the moving direction of the output end of the eighth driving member 510 is perpendicular to the conveying direction of the current transformer conveying track 310; a push rod 520, which is connected to the output end of the eighth driving member 510, one end of the push rod 520 passes through the second picking block 323 and is movably inserted into the second conveying trough 323a; a storage box 530, which is disposed on the frame 100; and a guide rail 540, which is inclinedly disposed on the frame 100, the inlet end of the guide rail 540 is located below the second picking block 323, and the outlet end of the guide rail 540 extends into the storage box 530.

[0089] The eighth drive unit 510 is preferably a cylinder, but it can also be a motor or hydraulic cylinder or other types of drive. After the conductive rod gripper 410 inserts one or two conductive rods 1 into the current transformer 4 and resets, the eighth drive unit 510 actuates, pushing the current transformer 4 with the conductive rod 1 installed into the guide rail via the pusher rod 520 at its output end. Since the guide rail is inclined, the current transformer 4 slides along the rail into the storage box 530 under its own gravity. The purpose of the design of the eighth drive unit 510, the pusher rod 520 and the storage box 530 is to remove and collect the current transformers 4 with the conductive rod 1 installed on the second picking block 323, so as to prepare for the installation of the next current transformer 4, thereby realizing the continuous production of current transformers 4 with the conductive rod 1 installed.
