[0045] Example 1

[0046] See also Figure 1-7 The present invention provides a technical solution: a nut assembly and terminal push-bending integrated processing equipment, comprising:

[0047] Rack 1;

[0048] The transfer line 2 includes a track 21, a first transfer shaft 22 and an equidistant lifting arm. The track 21 includes track units 211 that are symmetrically arranged facing each other. The track 21 is provided with a feeding station, a nut installation station, and a terminal crimping station that are equidistantly arranged in sequence. The equidistant lifting arm includes a first lifting cylinder 23 and a lifting plate 24. The first lifting cylinder 23 is fixedly mounted on a slider of the first transfer shaft 22. The lifting plate 24 is fixedly mounted on the output end of the first lifting cylinder 23. The lifting plate 24 extends into the gap between the two track units 211. The lifting plate 24 is provided with three positioning grooves 241 arranged along a straight line.

[0049] A feeding mechanism 3, which is used to transport the functional module 9 to the feeding station of the transfer line 2;

[0050] A nut-installing mechanism 4, which is used to suck and place nuts into a functional module 9 at a nut-installing station;

[0051] A terminal pressing mechanism, which is used to push and bend the pins 91 of the functional module 9 at the terminal pressing station;

[0052] The closing mechanism 6 is used to receive and store the processed functional modules 9 .

[0053] This makes the nut assembly and terminal bending of the electronic functional module efficient and fast, saves labor costs and improves production efficiency.

[0054] The feeding mechanism 3 includes a belt line 31, a push drive cylinder 32 and a push block 33. The functional module 9 is placed on the belt line 31. The push block 33 is fixedly mounted on the sliding seat of the push drive cylinder 32. The push block 33 is arranged at one end of the track 21. When the functional module 9 is loaded, it is manually arranged on the belt line 31. The belt line 31 automatically sends the frontmost functional module 9 to the pushing position. At the pushing position, the push drive cylinder 32 drives the push block 33 to move in a direction perpendicular to the conveying direction on the belt line 31. The push block 33 pushes the functional module 9 into the feeding station of the track 21.

[0055] The belt line 31 continuously replenishes the functional modules 9 to the feeding station. When the number of the functional modules 9 on the belt line 31 is insufficient, the device can emit an alarm sound to prompt the functional modules 9 to be replenished.

[0056] The nut loading mechanism 4 includes a vibration plate 41, a feeding track 42, a dividing cylinder 43 and a three-axis robot arm 44. The discharge port of the vibration plate 41 is connected to the feeding track 42. A direct vibration is arranged under the feeding track 42. The output end of the dividing cylinder 43 is connected to a dividing plate 431. A dividing trough is arranged on the dividing plate 431. A notch is arranged on the dividing trough facing the side of the feeding track 42. A suction nozzle 441 for adsorbing nuts is arranged on the three-axis robot arm 44.

[0057] When the nut loading mechanism 4 is working, the nuts in the vibration plate 41 are output to the feeding track 42, and the nuts are arranged in sequence and transported forward until they enter the dividing groove on the dividing plate 431 from the end of the feeding track 42. The dividing cylinder 43 drives the dividing plate 431 to slide toward the three-axis robot arm 44 to realize single nut loading, which facilitates the suction nozzle 441 of the three-axis robot arm 44 to absorb the nuts.

[0058] Afterwards, the three-axis robot arm 44 drives the sucked nut to move along the X-axis, Y-axis and Z-axis, and puts the nut into the corresponding hole of the functional module 9 at the nut installation station. The number of suction nozzles 441 can be set on the three-axis robot arm 44 according to needs.

[0059] The terminal pressing mechanism 5 includes a first pushing and bending unit 51, a second pushing and bending unit 52 and a downward pressing cylinder 53. The first pushing and bending unit 51 includes a first pushing and bending cylinder 511, a first pushing and bending block 512 and a first roller 513. The first pushing and bending block 512 is fixedly installed at the output end of the first pushing and bending cylinder 511. The first roller 513 is rotatably installed on the first pushing and bending block 512. The position of the first roller 513 corresponds to the pin 91. A pressing block 531 is arranged at the bottom of the downward pressing cylinder 53.

[0060] Since the functional module 9 in the present application has pins 91 on both sides, the pins 91 on both sides are bent respectively by the first bending unit 51 and the second bending unit 52. Specifically, when the terminal pressing mechanism 5 is working, the first bending cylinder 511 in the first bending unit 51 drives the first bending block 512 to extend, and the first roller 513 bends the pins 91 on one side of the functional module 9. The structure of the second bending unit 52 is the same as that of the first bending unit 51, and is used to bend the pins 91 on the other side of the functional module 9. Finally, the pressing block 531 at the bottom of the downward pressing cylinder 53 moves downward to squeeze the pins 91 so that the pins 91 fit the surface of the functional module 9.

[0061] If the terminal (ie, the pin 91 ) of the functional module 9 is unidirectional, it only needs to be bent once by one of the first bending unit 51 and the second bending unit 52 .

[0062] The closing mechanism 6 includes a material receiving tray 61, a horizontal pushing cylinder 62 and a pushing plate 63. The material receiving tray 61 is arranged at one end of the track 21. A material receiving notch corresponding to the position of the track 21 is arranged on the side wall of the material receiving tray 61. The pushing plate 63 is fixedly installed at the output end of the horizontal pushing cylinder 62.

[0063] After the functional modules 9 are processed, they are pushed into the receiving tray 61. After a plurality of functional modules 9 are arranged in a row, the horizontal push cylinder 62 drives the push plate 63 to push out, pushing the functional modules 9 in a row forward as a whole, making room for the next batch of functional modules 9 to be pushed into the receiving tray 61.

[0064] When the receiving tray 61 is full, the device will send out a beeping signal to prompt the operator to take out the full tray and put in the empty tray at the same time, so as to realize uninterrupted production.

[0065] Working principle: The transfer line 2 adopts an equidistant lifting and lowering transfer mode, so that the functional module 9 can be accurately transferred to each station. The loading mechanism 3 and the closing mechanism are respectively arranged at both ends of the transfer line 2, and the nut installation mechanism and the terminal pressing mechanism correspond to the nut installation station and the terminal pressing station on the track 21 of the transfer line 2, respectively, to realize the rapid and accurate transfer of the functional module 9 between different mechanisms.

[0066] When the transfer line 2 is working, the first transfer shaft 22 first drives the equidistant lifting arms to move to the feeding station and the nut installing station, the first positioning groove 241 on the lifting plate 24 is aligned with the functional module 9 of the feeding station, and the third positioning groove 241 is aligned with the functional module 9 of the nut installing station, and then the first lifting cylinder 23 drives the lifting plate 24 to lift, and the functional module 9 of the feeding station and the functional module 9 of the nut installing station are inserted into the lifting plate 24, and then the first transfer shaft 2 drives the equidistant lifting arms to move horizontally, so that the functional module 9 of the feeding station moves to the nut installing station, and the functional module 9 of the nut installing station moves to the terminal crimping station, and the original functional module 9 that has completed nut installation and terminal crimping at the terminal crimping station is pushed into the closing mechanism by the end face of the lifting plate 24.

[0067] Example 2

[0068] This embodiment further makes the following improved technical solutions on the basis of the above embodiments: the terminal crimping mechanism 5 also includes a secondary positioning cylinder 54, the output end of the secondary positioning cylinder 54 is connected to the secondary positioning block 541, and the secondary positioning block 541 is an "n"-shaped structure.

[0069] In order to enable the first push-bending unit 51 and the second push-bending unit 52 to accurately bend the pin 91, after the functional module 9 moves to the terminal crimping station of the track 21, the secondary positioning cylinder 54 drives the secondary positioning block 541 to extend, and the two ends of the functional module 9 respectively abut against an opposite inner wall of the secondary positioning block 541, thereby positioning the position of the functional module 9 on the track 21 to ensure the bending quality of the pin 91. After bending, before the pressing block 531 moves downward, the secondary positioning block 541 retracts.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
