Description

Technical Field

[0001] The invention belongs to the technical field of needle-threading type current transformer columnar devices, and in particular relates to an automatic assembly device for a transformer and a conductive rod. Background Art

[0002] The pin-type current transformer can convert the large current in the high-current line into a small current, usually into a standard current of 5A or 1A. For example, for a pin-type current transformer with a nominal ratio of 500 / 5, when the current on the primary side (i.e. the high-voltage side) is 500 amperes (A), the current on the secondary side (i.e. the low-voltage side) is 5 amperes (A). In this way, it is convenient to use an ordinary ammeter for measurement, ensuring that the measuring instrument works within a safe current range, so that the current can be accurately measured, providing accurate data for load management, fault diagnosis and energy metering of the power system.

[0003] like Figure 1 A needle-through current transformer 4 is shown, which includes a transformer 4 with a socket 5, into which one or two conductive rods 1 can be inserted. In the current production process, the needle-through current transformer 4 is mainly installed manually. Since the conductive rod 1 is small in size and U-shaped, and the socket 5 of the transformer 4 is also small, this results in a very labor-intensive production process. In particular, long-term focus on the docking of the conductive rod 1 and the socket 5 can easily cause visual fatigue and may damage the operator's eyesight. In addition, in order to correctly insert the conductive rod 1 into the socket 5 of the transformer 4, a certain amount of force needs to be applied, which means that pure manual operation or operation assisted by hard material tools may cause damage to the hands. In addition to potential injuries to the staff, there may also be problems such as insufficient insertion force, wrong direction, and the conductive rod 1 scratching the transformer 4. These problems not only reduce work efficiency, but also affect the yield rate. Summary of the invention

[0056] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0057] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0058] like Figures 2 to 10 As shown, an automatic assembly device for a mutual inductor and a conductive rod of the present invention comprises: a frame 100, a conductive rod conveying unit 200, a mutual inductor conveying unit 300, and an assembly unit 400.

[0059] In this solution, the mutual inductor 4 is provided with a socket 5 for inserting the conductive rod 1, and the conductive rod 1 is composed of a middle crossbar 2 and two extension rods 3 extending outward at a certain angle at both ends. Usually, 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, and the two extension rods 3 are located outside the mutual inductor 4.

[0060] The conductive rod transport unit 200, the transformer transport unit 300 and the assembly unit 400 are all installed on the frame 100. Preferably, the conductive rod transport unit 200 and the transformer transport unit 300 are arranged in parallel on the frame 100, and the assembly unit 400 is located therebetween. 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 vibration disk 230 to ensure that the conductive rod 1 is arranged in a predetermined direction and transported to the conductive rod transport unit 200. Similarly, the transformer transport unit 300 is also equipped with a transformer vibration disk 330 to ensure that the transformer 4 is transported to the transformer transport unit 300 in the set direction. In view of the fact that the working principle of the vibration disk is common knowledge in the industry, its specific structure will not be described in detail here.

[0061] The assembly unit 400 is provided with a conductive rod clamp 410, and the main function of the conductive rod clamp 410 is to grab the conductive rod 1 from the conductive rod conveying unit 200 and accurately assemble it into the socket 5 of the transformer 4. In order to complete the assembly between the conductive rod 1 and the transformer 4, the action of the conductive rod clamp 410 is divided into two parts: a grabbing stroke and an insertion stroke.

[0062] During the grabbing stroke, the conductive rod clamp 410 will lift the conductive rod 1 above the mutual inductor 4 and adjust the position of the conductive rod 1 so that the axis of its cross bar 2 forms an angle with the axis of the socket 5, so as to simulate the process of the conductive rod 1 being obliquely inserted into the socket 5 during manual assembly; during the insertion stroke, the extension rod 3 at one end of the conductive rod 1 close to the mutual inductor 4 (i.e., the extension rod 3 at the lower end) will enter the socket 5 due to the conductive rod clamp 410 pushing toward the mutual inductor 4, and the conductive rod 1 will be driven by the conductive rod clamp 410 to rotate relative to the mutual inductor 4, thereby passing through the socket 5, thereby realizing the successful assembly of the conductive rod 1 and the mutual inductor 4.

[0063] Preferably, the conductive rod clamp 410 is a pneumatic clamp, 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 approach each other and realizes the clamping and loosening operations of the conductive rod clamp 410.

[0064] Further preferably, the present solution further comprises 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 process of the entire automatic assembly device.

[0065] This solution realizes the automatic assembly of the needle-threading current transformer 4 by automating the conveying process of the conductive rod 1 and the transformer 4 and simulating manual assembly, thereby improving assembly efficiency, reducing manpower requirements in the production process, and improving 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 be laterally displaced when approaching the mutual inductor 4 under the drive of the conductive rod clamp 410, so as to allow the extension rod 3 on the side of the conductive rod 1 close to the mutual inductor 4 to be inserted into the mutual inductor 4; when in the rotating section, the extension rod 3 on the conductive rod 1 inserted into the mutual inductor 4 can pass through the insertion hole 5.

[0067] When the assembly unit 400 drives the conductive rod clamp 410 to move toward the transformer transport unit 300, so that the conductive rod 1 is located above the transformer 4, the lower extension rod 3 of the conductive rod 1 will be inserted into the socket 5 of the transformer 4 during the insertion stroke. Figure 3 In the process of the downward tilting movement shown, since the conductive rod 1 is obliquely approaching the 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 socket 5 of the transformer 4, and may even contact or collide with it, which may cause the conductive rod 1 to impact the transformer 4 and cause damage to the appearance of the transformer 4.

[0068] In order to avoid this situation, during the downward movement of the conductive rod 1, the assembly unit 400 controls the conductive rod clamp 410 to move laterally, that is, along the conductive rod 1. Figure 3 This process ensures that the conductive rod clamp 410 can prevent the conductive rod 1 from making unnecessary contact with the mutual inductor 4 while driving the conductive rod 1 to descend, thereby protecting the mutual inductor 4 from damage.

[0069] In this way, the assembly unit 400 not only realizes the precise insertion of the conductive rod 1, but also effectively avoids physical damage to the mutual inductor 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 driving member 430, which is arranged on the first support frame 420 along the length direction of the first support frame 420; a second driving member 440, which is connected to the output end of the first driving member 430 along the width direction of the first support frame 420, and the first driving member 430 is used to drive the second driving member 440 to move along the length direction of the first support frame 420; a third driving member 450, which is connected to the output end of the second driving member 440 along the height direction of the first support frame 420, and the second driving member 440 is used to drive the third driving member 450 to move along the width direction of the first support frame 420; a fourth driving member 460, which is connected to the output end of the third driving member 450, and the third driving member 450 is used to drive the fourth driving member 460 to move along the height direction of the first support frame 420, and the conductive rod clamp 410 is connected to the output end of the fourth driving member 460 to drive the conductive rod clamp 410 to rotate.

[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 driving member 430, the second driving member 440 and the third driving member 450 are preferably in the form of linear guides; of course, in addition to linear guides, these driving members can also be other types of drivers such as cylinders and oil cylinders. These three driving members are respectively arranged along the length, width and height directions of the first support frame 420, and are used to realize the front and back, left and right, and up and 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 mutual inductor transport unit 300.

[0072] The fourth driving member 460 is preferably a stepper motor, and its function is to drive the conductive rod 1 to rotate by rotating the conductive rod clamp 410. When the conductive rod 1 moves from the conductive rod transport unit 200 to the 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 transformer 4 socket 5. At the same time, the conductive rod clamp 410 can also be properly rotated during the insertion process to ensure accurate docking.

[0073] In the rotation section of the insertion stroke, when the conductive rod clamp 410 drives the conductive rod 1 to rotate, so that the extension rod 3 at the lower end of the conductive rod 1 passes through the socket 5 of the mutual inductor 4, due to processing errors that may occur during the manufacturing process (for example, the extension rods 3 at both ends of the conductive rod 1 and the cross bar 2 fail to remain vertical, or the socket 5 of the mutual inductor 4 is too small), the conductive rod 1 may scratch the mutual inductor 4 when rotating with the conductive rod clamp 410. If the scratching force is too large, it may scratch the surface of the mutual inductor 4, resulting in the appearance of embossing. In order to solve this problem, in this solution, a torque sensor 470 is installed between the fourth drive member 460 and the conductive rod clamp 410, and the sensor is electrically connected to the fourth drive member 460.

[0074] When the conductive rod 1 and the mutual inductor 4 begin to touch, the torque transmitted by the mutual inductor 4 to the torque sensor 470 through the conductive rod clamp 410 will be detected. At this time, the torque sensor 470 will trigger the fourth driving member 460 to adjust the angle of the conductive rod clamp 410 to deviate from the originally preset rotation angle, thereby allowing the conductive rod 1 to further rotate and pass through the jack 5 of the mutual inductor 4. Since the torque sensor 470 has a high sensitivity, it can detect when the conductive rod 1 and the mutual inductor 4 begin to contact, and respond quickly, so that the two can be separated even under a small contact force, thereby avoiding damage to the surface of the mutual inductor 4.

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

[0076] The conductive rod conveying track 210 preferably adopts a linear vibrator. A linear vibrator is a mechanical device that can generate periodic vibrations in a linear direction and is 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 vibration disk 230, and receives neatly arranged conductive rods 1 from the conductive rod vibration disk 230. The conductive rod conveying track 210 is responsible for secondary conveying of the conductive rods 1, and while ensuring that they are closely arranged, the conductive rods 1 are moved toward the direction of the conductive rod dividing mechanism 220. The function of the conductive rod dividing mechanism 220 is to deliver the closely arranged conductive rods 1 one by one to the position where the conductive rod clamp 410 can grasp them, thereby realizing the automatic loading of the conductive rods 1.

[0077] In order 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, and the sensor is electrically connected to the conductive rod vibrating plate 230. Since the conveying speed of the conductive rod vibrating plate 230 is relatively fast, and the material distribution speed of the conductive rod material distribution mechanism 220 may not be completely 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 will trigger a signal to suspend the work of the conductive rod vibrating plate 230 to ensure the normal operation of the conductive rod conveying unit 200.

[0078] Reference Figure 6 , Figure 7 , Figure 8 The conductive rod distributing mechanism 220 includes: a second support frame 221, which is arranged 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; a first material taking block 223, which is connected to the output end of the fifth driving member 222 and is movably arranged on the second support frame 221, and the first material taking block 223 is provided with a first material conveying trough 223a, and the first material conveying trough 223a 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 distributing mechanism 220. The fifth driving member 222 is preferably a cylinder, but it can also be other types of drivers such as a motor and a cylinder. The first material taking block 223 is equipped with a sensor electrically connected to the fifth driving member 222, and the sensing end of the sensor is facing the first material transport trough 223a. When working, the fifth driving member 222 pushes the first material taking block 223 so that the first material transport trough 223a on it is aligned with the discharge end of the conductive rod conveying track 210. When the sensor detects that the first material transport trough 223a has received the conductive rod 1 from the conductive rod conveying track 210, the fifth driving member 222 is actuated to drive the first material picking block 223 to move, thereby separating the conductive rod 1 in the first material transport trough 223a from other conductive rods 1 on the conductive rod conveying track 210, and transporting the conductive rod 1 to a position where the conductive rod clamp 410 can clamp it, so that the conductive rod clamp 410 can clamp the conductive rod 1 in the first material transport trough 223a.

[0080] In the present embodiment, the conductive rod material distributing mechanism 220 also includes a vacuum generator 224, which is arranged on the frame 100. The first material picking block 223 is provided with a gas channel 223b that runs through the first material picking block 223. One end of the gas channel 223b is connected to the first material transport trough 223a, and the other end is provided with an air pipe joint 225. The air pipe joint 225 is connected to the vacuum generator 224 through a pipeline to fix the conductive rod 1 in the first material transport trough 223a.

[0081] When the sensor detects that there is a conductive rod 1 in the first material transport trough 223a, the vacuum generator 224 is activated to extract air from the gas channel 223b to form a negative pressure in the gas channel 223b, thereby generating an adsorption force to firmly adsorb the conductive rod 1 in the first material transport 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 clamp 410 can accurately clamp the conductive rod 1.

[0082] Reference Figure 2 , Figure 3 and Fig. 9 The transformer transport unit 300 includes a transformer transport track 310 , a transformer material separation mechanism 320 is provided at the discharge end of the transformer transport track 310 , the transformers 4 are closely arranged on the transformer transport track 310 , and the transformer material separation mechanism 320 is used to transport the transformers 4 individually.

[0083] The feed end of the transformer conveying track 310 is connected to the discharge end of the transformer vibration plate 330, and receives the transformers 4 that are neatly arranged from the transformer vibration plate 330. In the preferred embodiment, the discharge end of the transformer conveying track 310 is provided with a sensor that is electrically connected to the transformer dividing mechanism 320. When working, when the sensor detects that the transformer 4 has been conveyed to the discharge end of the transformer conveying track 310, the transformer dividing mechanism 320 conveys the transformers 4 to the predetermined positions one by one, so as to facilitate the conductive rod clamp 410 to insert the conductive rod 1 into the transformer 4.

[0084] Reference Figure 2 , Figure 3 , Fig. 9 and Fig.10 The transformer dividing mechanism 320 includes: a third support frame 321, which is arranged on the frame 100; a sixth driving member 322, which is connected to the third support frame 321, and the moving direction of the output end of the sixth driving member 322 is perpendicular to the feeding direction of the transformer conveying track 310; a second material taking block 323, which is connected to the output end of the sixth driving member 322 and is movably arranged on the third support frame 321, and a second material conveying trough 323a is arranged on the second material taking block 323, and the second material conveying trough 323a is used to receive and convey the transformer 4 on the transformer conveying track 310; a seventh driving member 324, which is arranged on the frame 100 and is arranged opposite to the sixth driving member 322, and a blocking block 325 is arranged on the seventh driving member 324, and the blocking block 325 is movably abutted against the transformer 4 in the second material conveying trough 323a to provide a limit for the transformer 4.

[0085] The third support frame 321 is used to install and fix the entire transformer material distribution mechanism 320 on the frame 100. In the preferred embodiment, the third support frame 321 can be fixed to the frame 100 by threaded connection or welding. The sixth drive member 322 and the seventh drive member preferably use cylinders, and of course they can also be other types of drivers such as motors or oil cylinders. A sensor is provided on the second material taking block 323, which is directly opposite to the second material transport trough 323a and is electrically connected to the sixth drive member 322. When the transformer transport track 310 transports the transformer 4 to the second material transport trough 323a and is detected by the sensor, the sixth drive member 322 drives the second material taking block 323 to move, so that the transformer 4 in the second material transport trough 323a is separated from other transformers 4 on the transformer transport track 310, and transported to a predetermined position. After the transformer 4 is transported to its place, the seventh driving member drives the blocking block 325 to move to the opening of the second material transport trough 323a, providing a limit for the transformer 4 in the second material transport trough 323a, ensuring that when the conductive rod clamp 410 inserts the conductive rod 1 into the transformer 4, the transformer 4 remains fixed, thereby ensuring the normal installation of the transformer 4 and the conductive rod 1.

[0086] Reference Fig.10The second material taking block 323 is provided with a avoidance groove 323b which is connected with the second material transport groove 323a. When in the insertion stroke, the avoidance groove 323b is used to provide a avoidance 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, so that the extension rod 3 below the conductive rod 1 passes through the insertion hole 5 on the mutual inductor 4, the avoidance groove 323b provides sufficient passing space for the extension rod 3 to ensure normal insertion between the conductive rod 1 and the mutual inductor 4.

[0088] The present scheme also includes a material unloading unit 500, which is used to remove the mutual inductor 4 assembled with the conductive rod 1 in the second material transport trough 323a, and the material unloading 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 transport direction of the mutual inductor transport track 310; a pushing rod 520, which is connected to the output end of the eighth driving member 510, one end of the pushing rod 520 passes through the second material taking block 323 and is movably inserted in the second material transport trough 323a; a material storage box 530, which is arranged on the frame 100; a material guide track 540, which is obliquely arranged on the frame 100, the feeding end of the material guide track 540 is located below the second material taking block 323, and the discharging end of the material guide track 540 extends into the material storage box 530.

[0089] The eighth driving member 510 preferably adopts a cylinder, and of course, it can also be other types of drivers such as a motor or an oil cylinder. When the conductive rod clamp 410 inserts one or two conductive rods 1 into the mutual inductor 4 and resets, the eighth driving member 510 moves, and pushes the mutual inductor 4 with the conductive rod 1 installed into the material guide track through the push rod 520 set at its output end. Since the material guide track is inclined, the mutual inductor 4 slides along the track into the storage box 530 under the action of its own gravity. The design purpose of the eighth driving member 510, the push rod 520 and the storage box 530 is to remove and collect the mutual inductor 4 on which the conductive rod 1 has been installed on the second material removal block 323, so as to prepare for the installation of the next mutual inductor 4, thereby realizing the continuous production of the mutual inductor 4 plugged into the conductive rod 1.
