Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric energy metering device detection, and particularly relates to a detection device for electric energy metering device production. BACKGROUND

[0002] A current transformer is an instrument for converting a large current on a primary side into a small current on a secondary side for measurement according to the principle of electromagnetic induction. In power generation, power transformation, power transmission, power distribution and power consumption circuits, the current size is greatly different, and high voltage may be accompanied. In order to facilitate measurement, protection and control of the circuit, it is necessary to convert it into a relatively uniform current. The current transformer plays a role of current conversion and electrical isolation.

[0003] At present, a plastic shell type current transformer needs to wind a core first in the production process, and then the wound core is bonded and fixed in a lower shell through a dispensing method. Then, an upper shell and the lower shell are manually assembled together and placed on an ultrasonic heat sealing machine. The upper shell and the lower shell are welded together by the ultrasonic heat sealing machine to form a finished product of the current transformer. Finally, the finished product of the current transformer is transferred to a detection station for detection.

[0004] Defects of the current production method: workers need to manually assemble the upper shell and the lower shell together. After welding by the ultrasonic heat sealing machine, workers need to manually transfer the current transformer to the detection station for detection.

[0034] The upper shell 6 and the lower shell 601 in the application are two parts of the current transformer. The wound core is fixed in the lower shell 601 in advance, and the remaining steps only need to assemble the upper shell 6 and the lower shell 601 together, and then detect the assembled current transformer. The upper shell 6 and the lower shell 601 are assembled into a current transformer, and then placed on the pushing table 102 and located within the working stroke of the pushing rod 103. The pushing rod 103 is controlled to push the assembled current transformer to the ultrasonic heat sealer 101. At the same time, the pulling rod 105 also moves towards the ultrasonic heat sealer 101. Then the ultrasonic heat sealer 101 is controlled to weld the two together. After welding, the pneumatic clamping jaw 106 is started to clamp the welded current transformer. Then the pushing rod 103 and the pulling rod 105 are controlled to reset away from the ultrasonic heat sealer 101. The pulling rod 105 moves the welded current transformer out of the ultrasonic heat sealer 101, and moves the current transformer directly below the conductive rod 109, so that the conductive rod 109 passes through the middle of the current transformer, and the two poles of the current transformer face the two detection touch rods 111. Then the upper shell 6 and the lower shell 601 are assembled into a current transformer and placed on the pushing table 102. At the same time, the conductive rod 109 is controlled to pass through the conductive cylinder 108 and the current transformer. When the conductive rod 109 is connected with the two conductive cylinders 108, a closed circuit is formed. The circuit has a large primary side current. At the same time, the pneumatic slide plate 110 is controlled to approach the current transformer, so that the detection touch rod 111 contacts the two poles of the current transformer.

After detection, the conductive rod 109 is controlled to reset upwards, and the detected current transformer is taken off from the pulling table 104. Then the pulling rod 105 and the pushing rod 103 are controlled to move towards the ultrasonic heat sealer 101, so as to form a complete working cycle.

[0035] As Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the feeding mechanism for automatically placing the upper shell 6 on the lower shell 601 includes a material box 3, a lifting slide plate 301, feeding clamping plates 302, feeding cylinders 303 and a material blocking assembly. The material box 3 is fixed on the pushing table 102, and an F-shaped support is fixedly arranged on the base 1 to stabilize the material box 3. The lifting slide plate 301 is slidably connected to the outer wall of the material box 3 in the vertical direction. Two feeding clamping plates 302 are symmetrically and slidably connected to the lifting slide plate 301. The two feeding clamping plates 302 slide in the horizontal direction and can extend into the material box 3 to clamp the upper shell 6. Two feeding cylinders 303 are symmetrically fixed to the lifting slide plate 301. The extension shaft of the feeding cylinder 303 is fixed to an adjacent feeding clamping plate 302. The material blocking assembly is installed on the material box 3 and is used to block the upper shell 6 in the material box 3 from falling out. The material blocking assembly can be driven by the feeding clamping plate 302 to cancel the blocking of the upper shell 6 in the material box 3.

[0036] The upper shell 6 is stacked in the material box 3 in advance, and the material blocking mechanism blocks the upper shell 6 from directly falling out of the material box 3. After the pushing rod 103 and the pulling rod 105 are reset and the current transformer is moved directly below the conducting rod 109, the lower shell 601 is placed below the material box 3. The lower shell 601 is located within the stroke of the pushing rod 103 and directly below the upper shell 6 in the material box 3. The feeding cylinder 303 is controlled to drive the feeding clamping plate 302 to clamp the upper shell 6 at the same height in the material box 3. This upper shell 6 is the one located at the lowermost position. The lifting slide plate 301 is controlled to slide downward to drive the clamped upper shell 6 and the lower shell 601 below to be assembled together. The feeding cylinder 303 is controlled to drive the feeding clamping plate 302 to release the clamping of the upper shell 6. The lifting slide plate 301 is controlled to reset upward.

[0037] As shown in the drawings, Figures 6-8 The material blocking assembly includes a material blocking plate 4, a No. 401 spring and a top plate 402. The outer side of the material box 3 is symmetrically and slidably connected to two material blocking plates 4 through supports. The material blocking plate 4 is used to prevent the upper shell 6 in the material box 3 from falling out. A No. 401 spring is sleeved on the guide rod of the material blocking plate 4. When the two material blocking plates 4 move away from each other, the No. 401 spring is compressed. The top plate 402 is fixed to the feeding clamping plate 302. The two ends of the material blocking plate 4 are provided with inclined surfaces. When the feeding clamping plate 302 clamps the upper shell 6, the top plate 402 will drive the inclined surfaces on the material blocking plate 4 to move the material blocking plate 4 away from the lower side of the material box 3 to prevent the upper shell 6 from falling out.

[0038] When the feeding clamp plate 302 clamps the upper shell 6, the top plate 402 will extrude the material blocking plate 4, so that the two material blocking plates 4 move away from below the upper shell 6, so as not to block the downward movement of the upper shell 6 out of the material box 3. During the process of the feeding clamp plate 302 driving the upper shell 6 to move downward from the material box 3, since the material blocking plate 4 has a certain thickness, the top plate 402 will first keep in contact with the material blocking plate 4 to facilitate the downward movement of the upper shell 6, and then the material blocking plate 4 will reset under the action of the first spring 401 to continue to block the upper shell 6 in the material box 3.

[0039] As shown in Figure 6 and Figure 7 , it also includes a control mechanism for taking out only one upper shell 6 at a time, the control mechanism and the feeding clamp plate 302 are connected, the control mechanism includes a guide rod 5, a second spring 501 and a control clamp block 502, two guide rods 5 are symmetrically fixed on the feeding clamp plate 302, the second spring 501 is sleeved on the two guide rods 5, and the two guide rods 5 on the same feeding clamp plate 302 are connected with a control clamp block 502, the second spring 501 is located above the control clamp block 502, and the control clamp block 502 is slidably connected to the L-shaped small support on the side wall of the material box 3 in the horizontal direction, so that the control clamp block 502 can only move in the horizontal direction. When the feeding clamp plate 302 and the control clamp block 502 are away from each other, the second spring 501 will be compressed, and the control clamp block 502 can extend into the material box 3 to clamp the upper shell 6 of the same height.

[0040] When the feeding clamp plate 302 clamps the upper shell 6, the control clamp block 502 will be driven by the guide rod 5, so that the control clamp block 502 clamps the second upper shell 6 from bottom to top. Since the control clamp block 502 cannot move downward, the second spring 501 will be compressed during the downward conveying of the upper shell 6 by the feeding clamp plate 302, and the control clamp block 502 will keep clamping the upper shell 6 to prevent the stacked upper shells 6 in the material box 3 from falling out together. When the feeding clamp plate 302 releases the clamping of the upper shell 6, the two control clamp blocks 502 will move away from each other through the guide rod 5, and at this time the material blocking plate 4 has completed the reset, so that the upper shell 6 above can fall onto the material blocking plate 4 for clamping by the feeding clamp plate 302.

[0041] Example 2: Based on example 1, as shown in Figure 5 and Figure 6As shown, the pushing mechanism is connected with the material box 3, and comprises a pushing rod 703 and a pushing block 702. The material box 3 is provided with two cavities of different lengths, one of which is shorter and used for stacking the upper shell 6, and the other of which is longer and used for stacking the lower shell 601. The shorter cavity is located at a higher position than the longer cavity, so as to push the lower shell 601 below the upper shell 6. The pushing rod 703 is connected with the pushing platform 102 through a support in a horizontal sliding manner, and the sliding direction of the pushing rod 703 is perpendicular to the pushing rod 103. The pushing rod 703 is connected with the material box 3 in a sliding manner, and is used for pushing the lower shell 601 at the lowermost position in the material box 3 to the position directly below the other cavity, so that the feeding mechanism can butt joint the upper shell 6 and the lower shell 601. The pushing block 702 is fixed on the pushing platform 102, and cooperates with the pushing rod 703 to position the lower shell 601.

[0042] During the movement of the feeding clamping plate 302 to move the upper shell 6 downward, the pushing rod 703 pushes the lower shell 601 at the lowermost position in the material box 3 to the direction of the pushing block 702. The pushing rod 703 and the pushing block 702 cooperate to position the lower shell 601, so that the lower shell 601 can be moved to the position directly below the upper shell 6.

[0043] As shown in Figure 5 and Figure 6 The pushing mechanism further comprises a transmission guide frame 7 and a transmission frame 701. The transmission guide frame 7 is fixed on the lifting slide plate 301, and the transmission guide frame 7 is provided with a V-shaped sliding groove. The transmission frame 701 is fixed on the pushing rod 703, and the upper side of the transmission frame 701 is connected with the sliding groove in the transmission guide frame 7 in a sliding manner. When the lifting slide plate 301 moves downward, the transmission frame 701 drives the pushing rod 703 to extend into the material box 3 under the guidance of the sliding groove.

[0044] The lifting slide plate 301 and the transmission guide frame 7 move downward synchronously. The sliding groove in the transmission guide frame 7 comprises two sections. One section is inclined, so that the transmission guide frame 7 can drive the pushing rod 703 to enter the material box 3 through the transmission frame 701. The other section is vertical, so that the pushing rod 703 does not move after pushing the lower shell 601 to the set position, and the lifting slide plate 301 can continue to move downward to assemble the upper shell 6 and the lower shell 601.

[0045] As shown in Figure 2As shown, the device also comprises a driving mechanism for driving the lifting slide plate 301 and the conductive rod 109 to lift, the driving mechanism is installed on the base 1, and the driving mechanism comprises a driving plate 8, a main cylinder 801 and a driving support 802, the driving support 802 is fixedly connected to the base 1, the driving plate 8 is slidably connected to the driving support 802 in the vertical direction, the driving plate 8 is in the shape of a concave letter, the main cylinder 801 is fixedly connected to the top of the driving support 802, the telescopic shaft of the main cylinder 801 is fixedly connected to the top of the driving plate 8, the upper end of the conductive rod 109 is fixedly connected to the driving plate 8, and in order to avoid interference of the driving plate 8 with the circuit, an insulating material needs to be used to isolate the conductive rod 109 and the driving plate 8, and the top of the transmission guide frame 7 is also fixedly connected to the driving plate 8.

[0046] When the main cylinder 801 extends or retracts, the driving plate 8 will move in the vertical direction, thereby driving the conductive rod 109, the transmission guide frame 7 and the lifting slide plate 301 to move synchronously.
