[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Refer to Figures 1-7 , a feeding mechanism applied to a transformer testing equipment, the transformer testing equipment includes a soldering dipping connection component 10, a transfer component 30, and a testing component 20 that are connected in sequence from the back to the front;

[0027] The soldering dipping connection component 10 is used to connect to a soldering dipping equipment 102 and sequentially convey the network transformers that have completed soldering dipping to the transfer component 30 one by one;

[0028] The transfer component 30 is used to transfer the network transformer to the testing component 20;

[0029] The testing component 20 is used to test the network transformer.

[0030] Based on the above embodiments, the present utility model, through the soldering dipping connection component, under the action of a manipulator, arranges the network transformers that have completed soldering dipping in sequence from the back to the front on the soldering dipping connection component, and the soldering dipping connection component then 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 omits 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.

[0031] Refer to Figure 1 , the soldering dipping 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;

[0032] The tin dipping connection assembly 10 further includes a pusher mechanism 130 for pushing the network transformer on the conveying bracket 120 into the transfer assembly 30;

[0033] The pusher mechanism 130 includes a second linear reciprocating movement assembly 131. A first cylinder 132 is fixedly installed on the moving end of the second linear reciprocating movement assembly 131, and a push rod 133 is installed on the cylinder shaft of the first cylinder 132.

[0034] During actual connection test transportation, the manipulator grabs the tin-dipped network transformer and arranges it in a straight line from front to back on the conveying bracket 120. Then, under the action of the first linear reciprocating movement assembly 110, it can drive the conveying bracket 120 to move forward and connect with the input end of the transfer assembly 30. Then, under the action of the pusher mechanism 130, the second linear reciprocating movement assembly 131 drives the first cylinder 132 and the push rod 133 to move forward, and pushes the network transformer into the transfer assembly 30 from back to front.

[0035] 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, the first cylinder 132 needs to drive the push rod 133 to rise to avoid position interference.

[0036] See Figure 1 and Figure 2 , 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;

[0037] 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;

[0038] A conveying track 340 is provided on the front side of the transfer track 320;

[0039] The output end of the conveying track 340 is connected to a transfer seat 350;

[0040] A pusher device 330 is provided above the transfer track 320 for pushing the network transformers in the transfer track 320 into the conveying track 340 one by one.

[0041] The number of transfer tracks 320 is set according to the test component 20. When there are two test components 20, then two transfer tracks 320 are also set. When two transfer tracks 320 are set, the function of the third linear reciprocating movement component 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.

[0042] The conveying principle of the transfer component 30 is that under the action of the pushing mechanism 130, it can push the network transformer on the conveying bracket 120 from the back to the front into the transfer track 320. Then, under the action of the third linear reciprocating movement component 310, the transfer track 320 is connected with the conveying track 340. Then, the network transformer in the transfer track 320 is pushed into the conveying track 340 through the pushing device 330. And for the network transformer at the output end of the conveying track 340, affected by the rear 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 component 20 one by one.

[0043] Further, referring to Figure 2 and Figure 3 As shown in FIGS. and, the pushing 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. A dial block 334 is installed on the cylinder shaft of the ninth cylinder 333.

[0044] Under the action of the fifth linear reciprocating movement component 332, it can drive the dial block 334 to move back and forth, so that the dial block 334 can push the network transformer located in the rotating track 320 forward. The function of the ninth cylinder 333 is to drive the dial block 334 to move up and down, so that when the dial block 334 is behind the transfer track 320, the ninth cylinder 333 can drive the dial 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 dial block 334 to move up to prevent the dial block 334 from pushing the network transformer backward again during the backward reset movement.

[0045] Referring to Figure 5, the test component 20 includes a test track 210. The transfer seat 350 is movably arranged relative to the transformer test device 101. A second cylinder 360 for driving the movement of the transfer seat 350 is provided on the transformer test device 101. The second cylinder 360 is used to drive the transfer seat 350 to reciprocate between the input end of the test track 210 and the output end of the conveying track 340. Test cylinders 60 are arranged on the left and right sides of the test track 210. A plurality of test needles in contact with the pins of the network transformer are installed on the cylinder shafts of the test cylinders 60. A feeding component 50 for driving the network transformer to move from the transfer seat 350 to the test track 210 is arranged above the test track 210. In this embodiment, under the action of the second cylinder 360, it can drive the transfer seat 350 to displace, so as to realize connection with the conveying track 340 or connection with the test track.

[0046] Testing principle of the test component 20: When the transfer seat 350 carries the network transformer and completes connection with the test 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 test track 210 and move it to the test area. Then, under the action of the left and right test cylinders 60, the test needles are brought into contact with the pins of the network transformer to be energized for function detection.

[0047] Further, after the test needles complete the test, the feeding component 50 continues to push the tested network transformer forward to enter the next process.

[0048] See Figure 7 , the feeding component 50 includes a moving seat 510 movably arranged on the transformer test device 101. A third cylinder 520 for driving the forward and backward movement of the moving seat 510 is provided on the transformer test device 101.

[0049] 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 an open lower end and capable of accommodating at least one network transformer is arranged on the pushing plate 540.

[0050] 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.

[0051] See Figure 5 and Figure 6 On one side of the output end of the test track 210, a defective product recycling mechanism 40 for collecting defective products is provided on the transformer test device 101. The defective product recycling mechanism 40 is used to recycle the network transformers that fail the test on the test track 210, so as to distinguish between good products and defective products.

[0052] See Figure 5 and Figure 6 The defective product recycling mechanism 40 includes a hose stacking rack 410. Limiting slots 412 are respectively provided 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 provided at the lower part of the front side of the hose stacking rack 410, and the input port 411 communicates with the lowermost hose 401;

[0053] On the transformer test device 101 on the front side of the hose stacking rack 410, a recycling seat 430 that moves left and right relative to the transformer test device 101 is provided. On the transformer test device 101, a fourth linear reciprocating movement assembly 400 for driving the recycling seat 430 to move towards the test track 210 is provided;

[0054] 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 provided at the rear side of the input port 411;

[0055] On the transformer test device 101, a fifth cylinder 490 is provided. A mounting seat 450 is installed on the cylinder shaft of the fifth cylinder 490. A sixth cylinder 460 is provided on the mounting seat 450. A mounting plate 470 is installed on the cylinder shaft of the sixth cylinder 460. A pneumatic claw 480 for gripping the network transformer is installed on the mounting plate 470.

[0056] Principle of recycling defective products: The fifth cylinder 490 is responsible for driving the pneumatic claw 480 to move to the output end of the test track 210. Then, under the combined action of the sixth cylinder 460 and the pneumatic claw 480, the network transformer is gripped. Then, through the continuous movement of the fifth cylinder 490, the pneumatic claw 480 is driven to move above the recycling seat 430. Then, under the combined action of the sixth cylinder 460 and the pneumatic claw 480, the network transformer is placed into the recycling seat 430. Then, through the fourth linear reciprocating movement assembly 400, the recycling seat 430 is driven 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 to enter the hose 401 through the input port 411 for storage.

[0057] See Figure 6, a notch 416 is provided at the lower part of any one of the left and right sides of the hose 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 hose 401 at the bottom of the hose stacking rack 410, so that it can be separated from the hose stacking rack 410 through the notch 416.

[0058] A collection bin 413 for collecting the hose 401 is installed on the transformer testing device 101 on the same side as the notch 416.

[0059] The notch 416 is provided so that the front and rear ends of the hose 401 can move from the notch 416 to the outside of the hose stacking rack 410. The notch 416 and the seventh cylinder 420 are used in cooperation. When the hose 401 is filled with defective network transformers, at this time, it is pushed by the seventh cylinder 420, so that the hose 401 moves from the notch 416 to the outside of the hose stacking rack 410 to realize separation from the hose stacking rack 410.

[0060] 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. 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 separating 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.

[0061] In the present utility model, the first linear reciprocating movement assembly 110, the second linear reciprocating movement assembly 131, the third linear reciprocating movement assembly 310, and the fourth linear reciprocating movement assembly 400 can adopt existing linear movement mechanisms, as long as they can achieve linear reciprocating movement, and will not be elaborated here one by one.
