Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figure 3It is a structural schematic view of an embodiment of the inductor picking device. Figure 3 As shown in the figure, the inductor picking device is used for picking inductors 39 with height difference, and comprises a base 31, two suction assemblies, a power assembly 33 and a transmission assembly 34. The base 31 is provided with a cavity 310, and the base 31 comprises a first side 311 and a second side 312 arranged oppositely. The two suction assemblies are arranged side by side on the first side 311 of the base 31 and partially located in the cavity 310. The suction assemblies can move in the direction of approaching or moving away from the base 31. One end of each of the two suction assemblies located in the cavity 310 is provided with an inclined surface 320, and the two inclined surfaces 320 are arranged oppositely. The power assembly 33 is arranged on the second side 312 of the base 31. The power assembly 33 comprises two gas pipes arranged side by side and used for conveying power gas into the cavity 310. The two gas pipes are arranged correspondingly to the two suction assemblies. The transmission assembly 34 is arranged in the cavity 310 and between the two inclined surfaces 320. The transmission assembly 34 comprises a seesaw 341. The seesaw 341 is fixed in the cavity 310 by a fixing member 342 and can rotate around the fixing member 342. The transmission assembly 34 can rotate from the horizontal state to the corresponding suction assembly by the seesaw 341 under the pushing of the power gas transmitted by a certain gas pipe to push the suction assembly.

[0025] The above technical solution sets the power assembly and the movable suction assembly on the fixed base and sets the transmission assembly in the cavity of the base. After one suction assembly picks the inductor, the other suction assembly is pushed to continue moving by the power gas and the seesaw gravity principle to pick the inductor with different height, so that the inductor is prevented from falling off during transportation. The inductor picking device has simple structure design and high benefits.

[0026] In some embodiments, the base 31 is a support fixed base, which is convenient to fix on the corresponding clamping mechanism of the machine table.

[0027] In some embodiments, the suction assembly further comprises a moving member 323 and a suction member 324. The moving member 323 is arranged in the cavity 310. The suction member 324 is connected to the moving member 323 and extends out of the base 31. The moving member 323 is used to drive the suction member 324 to move in the direction of approaching or moving away from the base 31.

[0028] In some embodiments, the inclined surface 320 is arranged on the moving member 323. In the present embodiment, the moving member 323 is a right triangular prism structure, and the inclined surface of the triangular prism is the inclined surface 320 of the pickup assembly. The base of the triangular prism is connected to the pickup member 324 to drive the pickup member 324 to move towards or away from the base 31.

[0029] In some embodiments, the pickup member 324 is provided with a vacuum channel 325 connected to a vacuum pump (not shown) of a machine table. A magnetic valve (not shown) is arranged between the vacuum channel 325 and the vacuum pump of the machine table to control the opening and closing of the vacuum channel 325.

[0030] In some embodiments, the power gas is compressed air, and the two gas supply pipes are connected to a gas supply pipeline of a machine table. A magnetic valve (not shown) is arranged between the gas supply pipe and the gas supply pipeline of the machine table to control the opening and closing of the gas supply pipe.

[0031] In some embodiments, after the power assembly 33 picks up the inductor 39 by one of the pickup assemblies 321, the corresponding gas supply pipe 331 stops delivering power gas. The seesaw 341 is rotated by the power gas delivered by the other gas supply pipe 332 to push the other pickup assembly 322. At this time, the corresponding gas supply pipe 332 of the other pickup assembly 322 continues to deliver power gas, the horizontal state of the seesaw 341 is destroyed, and the seesaw 341 is rotated around the fixed member 342 by the power gas delivered by the gas supply pipe 332 to the other pickup assembly 322. The seesaw 341 engages with the inclined surface 320 to move up and down to push the other pickup assembly 322 away from the base 31 and close to the inductor 39 until the pickup assembly 322 contacts the inductor 39 and adsorbs the inductor 39 through the vacuum channel 325, so that both pickup assemblies pick up the inductor 39.

[0032] In some embodiments, the cavity 310 can maintain an airtight state after both pickup assemblies pick up the inductor 39. After both pickup assemblies pick up the inductor 39, both gas supply pipes stop delivering gas, and the cavity 310 maintains an airtight state to keep the relative positions of the two pickup assemblies unchanged.

[0033] In some embodiments, the seesaw 341 is a triangular prism, and the fixed member 342 is located at the center of the triangular prism.

[0034] In some embodiments, the power assembly 33 further comprises a vacuum tube 333, which is arranged on the second side 312 of the base 31 and between the two air feeding tubes, and which is capable of releasing the power gas in the cavity 310 after the transmission of the inductor 39 is completed.

[0035] In some embodiments, the seesaw 341 is capable of returning to the horizontal state after the power gas in the cavity 310 is released, and the two suction assemblies are capable of returning to the same height after the power gas in the cavity 310 is released. The seesaw 341 and the two suction assemblies return to the initial state after the power gas in the cavity 310 is released, so as to perform the next working cycle.

[0036] The working process of the inductor picking device is as follows:

[0037] (1) When the inductor picking device does not start picking up, it is in the initial state, the cavity 310 is in a vacuum state, the seesaw 341 remains in a horizontal state, and the two suction assemblies are at the same height. The two suction assemblies are provided with a telescopic connecting piece (not shown), and the telescopic connecting piece is located in the cavity 310, and the two suction assemblies are fixed in the base through the telescopic connecting piece.

[0038] (2) When the inductor picking device starts picking up the inductor 39, the inductor picking device moves towards the inductor 39 as a whole, and the two air feeding tubes of the power assembly 33 simultaneously feed power gas to the seesaw 341, at this time the seesaw 341 still remains in a horizontal state, and the two suction assemblies are at the same height.

[0039] (3) Due to the height difference between the two inductors 39, one of the two suction assemblies 321 first reaches the surface of the inductor 39 and adsorbs the inductor 39 through the vacuum channel 325, at this time the vacuum channel 325 of the suction assembly 321 meets the negative pressure value, the corresponding air feeding tube 331 of the suction assembly 321 stops feeding power gas, and the inductor picking device stops moving towards the inductor 39.

[0040] (4) After the power gas stops being delivered by the air pipe 331 corresponding to the suction assembly 321, the power gas continues to be delivered by the other air pipe 332, the horizontal state of the seesaw 341 is destroyed, the seesaw 341 rotates around the fixed part 342 towards the other suction assembly 322 under the pushing of the power gas delivered by the air pipe 332, the seesaw 341 moves up and down in cooperation with the inclined surface 320 to push the other suction assembly 322 away from the base 31 and close to the inductor 39. At this time, the telescopic connecting part in the suction assembly 322 is compressed. The air pipe 332 continues to deliver power gas until the suction assembly 322 also reaches the surface of the inductor 39 and adsorbs the inductor 39 through the vacuum channel 325. At this time, the vacuum channel 325 of the suction assembly 322 meets the requirement of the negative pressure value, the air pipe 332 corresponding to the suction assembly 322 stops delivering power gas, and the cavity 310 remains in a gas-tight state.

[0041] (5) When the negative pressure values of the vacuum channels of the two suction assemblies meet the requirement, the inductor picking device completes the picking action, the inductor 39 is separated from the carrier and transported to the next workbench.

[0042] (6) After the inductor 39 reaches the next workbench, the vacuum state of the vacuum channels 325 of the two suction assemblies is released first, and then the power gas in the cavity 310 is released through the vacuum pipe 333 of the power assembly 33 to restore the vacuum state of the cavity 310. At this time, the seesaw 341 returns to the horizontal state, at this time, the telescopic connecting part in the suction assembly 322 rebounds to drive the suction assembly 322 to move towards the base 31 until it returns to the initial state and is flush with the suction assembly 321.

[0043] (7) Repeat steps (1)-(6) to complete the picking and transporting of multiple groups of inductors 39.

[0044] The technical scheme has the advantages that the power assembly and the movable suction assembly are arranged on the fixed base, the transmission assembly is arranged in the cavity of the base, after one suction assembly picks up the inductor, the other suction assembly is pushed to continue moving by the power gas and the gravity principle of the seesaw to pick up inductors of different heights, so that the inductors are prevented from falling off during transportation, the inductor picking device has simple structure and high efficiency.
