[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Refer to Figures 1-7 , a defective product recycling mechanism of a transformer testing device, including a soldering dip connection component 10, a transfer component 30, and a testing component 20 that are sequentially connected from the rear to the front;

[0024] The soldering dip connection component 10 is used to connect to a soldering dip device 102 and sequentially convey the network transformers that have completed soldering dip to the transfer component 30 one by one;

[0025] The transfer component 30 is used to transfer the network transformers to the testing component 20;

[0026] The testing component 20 is used to test the network transformers.

[0027] Based on the above embodiments, the present utility model, through the soldering dip connection component, under the action of a manipulator, arranges the network transformers that have completed soldering dip one by one from the rear to the front on the soldering dip connection component, and then the soldering dip connection component conveys the network transformers to the transfer component. Under the action of the transfer component, they enter the corresponding testing component for testing. The present utility model eliminates the use of trays, not only saving the cost of trays, but also eliminating the need to store trays after testing, improving the testing operation efficiency.

[0028] Refer to Figure 1 , the soldering dip connection component 10 includes a first linear reciprocating movement component 110, a conveying bracket 120 is fixedly installed on the moving end of the first linear reciprocating movement component 110, and the network transformers are arranged on the conveying bracket 120;

[0029] The soldering dip connection component 10 further includes a pushing mechanism 130 for pushing the network transformers on the conveying bracket 120 into the transfer component 30;

[0030] The pushing mechanism 130 includes a second linear reciprocating movement component 131, a first air cylinder 132 is fixedly installed on the moving end of the second linear reciprocating movement component 131, and a push rod 133 is installed on the cylinder shaft of the first air cylinder 132.

[0031] During actual connection testing and transportation, the manipulator grabs the network transformers after soldering dip and arranges them in a straight line from the front to the rear on the conveying bracket 120. Then, under the action of the first linear reciprocating movement component 110, it can drive the conveying bracket 120 to move forward and connect with the input end of the transfer component 30. Then, under the action of the pushing mechanism 130, the second linear reciprocating movement component 131 drives the first air cylinder 132 and the push rod 133 to move forward, and pushes the network transformers into the transfer component 30 from the rear to the front.

[0032] In the above embodiment, the first cylinder 132 can drive the push rod 133 to move up or down. This position movement is to cooperate with the forward and backward movement of the conveying bracket 120. When it is necessary to push the network transformer into the transfer assembly 30, the first cylinder 132 drives the push rod 133 to move to the same height as the network transformer. When the conveying bracket 120 needs to move forward and backward, it is necessary to drive the push rod 133 to rise through the first cylinder 132 to avoid position interference.

[0033] See Figure 1 and Figure 2 As shown in, the transfer assembly 30 includes a third linear reciprocating movement assembly 310, and at least one transfer track 320 is provided on the third linear reciprocating movement assembly 310;

[0034] The moving direction of the third linear reciprocating movement assembly 310 is perpendicular to the moving direction of the first linear reciprocating movement assembly 110;

[0035] A conveying track 340 is provided on the front side of the transfer track 320;

[0036] The output end of the conveying track 340 is connected to a transfer seat 350;

[0037] Above the transfer track 320, there is a pushing device 330 for pushing the network transformers in the transfer track 320 one by one into the conveying track 340.

[0038] The number of transfer tracks 320 is set according to the test assembly 20. When there are two test assemblies 20, then two transfer tracks 320 are also provided. When two transfer tracks 320 are provided, the function of the third linear reciprocating movement assembly 310 is to drive the rotating track 320 to move left and right to switch different transfer tracks to connect with the conveying bracket 120.

[0039] The conveying principle of the transfer assembly 30 is that under the action of the pushing mechanism 130, it can push the network transformers on the conveying bracket 120 from the rear to the front into the transfer track 320. Then, under the action of the third linear reciprocating movement assembly 310, the transfer track 320 is connected to the conveying track 340. Then, the pushing device 330 pushes the network transformers in the transfer track 320 into the conveying track 340. And for the network transformers at the output end of the conveying track 340, affected by the rearward thrust, at least one network transformer enters the transfer seat 350. Based on this conveying principle, under the action of the transfer seat 350, the network components can enter the test assembly 20 one by one.

[0040] Further, see Figure 2 and Figure 3, the pusher device 330 includes a gantry 331 fixedly arranged on the transformer testing device 101. At least one fifth linear reciprocating movement component 332 is installed on the gantry 331. A ninth cylinder 333 is installed on the moving end of the fifth linear reciprocating movement component 332, and a pushing block 334 is installed on the cylinder shaft of the ninth cylinder 333.

[0041] Under the action of the fifth linear reciprocating movement component 332, it can drive the pushing block 334 to move back and forth, so that the network transformer located on the rotating track 320 can be pushed forward through the pushing block 334. The function of the ninth cylinder 333 is to drive the pushing block 334 to move up and down, so that when the pushing block 334 is located behind the transfer track 320, the ninth cylinder 333 can drive the pushing block 334 to move down to the same height as the network transformer to push the network transformer forward. When a round of pushing is completed, the ninth cylinder 333 drives the pushing block 334 to move up to prevent the pushing block 334 from pushing the network transformer backward again during the backward reset movement.

[0042] See Figure 5 , the testing component 20 includes a testing track 210. The transfer seat 350 is movably arranged relative to the transformer testing device 101. A second cylinder 360 for driving the transfer seat 350 to move is arranged on the transformer testing device 101; the second cylinder 360 is used to drive the transfer seat 350 to reciprocate between the input end of the testing track 210 and the output end of the conveying track 340. Testing cylinders 60 are arranged on the left and right sides of the testing track 210, and a number of testing needles in contact with the pins of the network transformer are installed on the cylinder shafts of the testing cylinders 60; a feeding component 50 for driving the network transformer to move from the transfer seat 350 to the testing track 210 is arranged above the testing track 210. In this embodiment, under the action of the second cylinder 360, it can drive the transfer seat 350 to displace to achieve connection with the conveying track 340 or connection with the testing track.

[0043] Testing principle of the testing component 20: When the transfer seat 350 carries the network transformer and completes connection with the testing track 210 under the action of the second cylinder 360, the feeding component 50 can push the network transformer located on the transfer seat 350 into the testing track 210 and move it to the testing area. Then, under the action of the left and right testing cylinders 60, the testing needles are brought into contact with the pins of the network transformer to be energized for functional testing.

[0044] Furthermore, after the testing needles complete the test, the feeding component 50 continues to push the network transformer that has completed the test forward to enter the next process.

[0045] See Figure 7, the feeding assembly 50 includes a moving seat 510 movably arranged on the transformer testing device 101, and a third cylinder 520 for driving the moving seat 510 to move back and forth is arranged on the transformer testing device 101;

[0046] A fourth cylinder 550 is installed on the moving seat 510. A lifting plate 530 is arranged on the cylinder shaft of the fourth cylinder 550. At least one pushing plate 540 is arranged on the lifting plate 530. A pushing space 541 with a lower end opening and capable of accommodating at least one network transformer is arranged on the pushing plate 540.

[0047] When pushing the network transformer from the transfer seat 350 into the test track 210, first drive the moving seat 510 to move through the third cylinder 530, so that the pushing space 541 moves above the network transformer. Then, under the action of the fourth cylinder 550, the lifting plate 530 and the pushing plate 540 move downward, so that the network transformer is embedded in the pushing space 541. Then, with the forward drive of the third cylinder 520, it can drive the moving seat, the lifting plate, the pushing plate 540 and the network transformer to move forward together.

[0048] See Figure 5 and Figure 6 , a defective product recycling mechanism 40 for collecting defective products is arranged on the transformer testing device 101 on one side of the output end of the test track 210. The defective product recycling mechanism 40 is used to recycle the network transformers that are unqualified in the output of the test track 210 to distinguish between good products and defective products.

[0049] See Figure 5 and Figure 6 , the defective product recycling mechanism 40 includes a hose stacking rack 410. Limiting slots 412 are respectively arranged on the front and rear sides of the hose stacking rack 410. The front and rear ends of the hose 401 are inserted into the limiting slots 412. An input port 411 is arranged at the lower part of the front side of the hose stacking rack 410, and the input port 411 is communicated with the lowermost hose 401;

[0050] A recycling seat 430 that moves left and right relative to the transformer testing device 101 is arranged on the transformer testing device 101 on the front side of the hose stacking rack 410. A fourth linear reciprocating moving assembly 400 for driving the recycling seat 430 towards the test track 210 is arranged on the transformer testing device 101;

[0051] A recycling pushing cylinder 440 for pushing the network transformer so that the network transformer enters the hose 401 from the input port 411 is arranged at the rear side of the input port 411;

[0052] A moving component is provided on the transformer testing device 101, and a grasping element 480 is installed on the moving component;

[0053] The moving component includes a fifth cylinder 490. An installation seat 450 is installed on the cylinder shaft of the fifth cylinder 490. A sixth cylinder 460 is provided on the installation seat 450. An installation plate 470 is installed on the cylinder shaft of the sixth cylinder 460. The grasping element 480 is arranged on the installation plate 470.

[0054] Principle of defective product recycling: The fifth cylinder 490 is responsible for driving the grasping element 480 to move to the output end of the test track 210. Then, under the combined action of the sixth cylinder 460 and the grasping element 480, the network transformer is grasped. Then, the fifth cylinder 490 continues to move to drive the grasping element 480 to move above the recycling seat 430. Then, under the combined action of the sixth cylinder 460 and the grasping element 480, the network transformer is placed into the recycling seat 430. Then, the fourth linear reciprocating moving component 400 drives the recycling seat 430 to move, so that the recycling seat 430 is connected to the input port 411. After the connection is completed, under the action of the recycling pushing cylinder 440, it can push the network transformer located in the recycling seat 430 into the rubber tube 401 through the input port 411 for storage.

[0055] Further, the grasping element 480 is a pneumatic claw or a vacuum suction nozzle.

[0056] See Figure 6 As shown, a notch 416 is provided at the lower part of either the left or right side of the rubber tube stacking rack 410. A seventh cylinder 420 is provided on the transformer testing device 101 on the opposite side of the notch 416. The seventh cylinder 420 can push the rubber tube 401 at the bottom of the rubber tube stacking rack 410, so that it can move out of the rubber tube stacking rack 410 through the notch 416;

[0057] A collection bin 413 for collecting the rubber tube 401 is installed on the transformer testing device 101 on the same side as the notch 416.

[0058] The setting of the notch 416 enables the front and rear ends of the rubber tube 401 to move from the notch 416 to the outside of the rubber tube stacking rack 410. The combined use of the notch 416 and the seventh cylinder 420. When the rubber tube 401 is filled with defective network transformers, at this time, it is pushed by the seventh cylinder 420 to make the rubber tube 401 move out of the notch 416 to the outside of the rubber tube stacking rack 410, so as to realize the separation from the rubber tube stacking rack 410.

[0059] See Figure 6, a limiting block 414 is hinged on the hose stacking rack 410 above the notch 416. An eighth cylinder 415 is hinged on the hose stacking rack 410, and the cylinder shaft of the eighth cylinder 415 is hinged with the limiting block 414. The function of the limiting block 414 is to block the notch 416 to prevent the hose 401 from disengaging outward from the notch 416. When it is necessary to push the hose 401 out of the hose stacking rack 410, the eighth cylinder 415 drives the limiting block 414 to displace to release the limit.
