Description

Technical Field

[0001] The utility model relates to a terminal crimping assembly device, in particular to a full-automatic crimping assembly mechanism for a shell product. Background Art

[0002] In the process of automation of existing crimping assembly mechanisms, some problems will arise in the automation process of each link, making the efficiency of fully automated assembly crimping low, such as the problem of posture adjustment of the workpiece at the beginning of loading. Often, the wrong posture of the workpiece at the beginning of the process will greatly affect the efficiency of the entire assembly crimping and will affect the product yield; for example, the inefficiency caused by the inability to transfer and crimp the workpieces simultaneously. In the prior art, the transfer mechanism and the crimping mechanism are often separately arranged, which firstly occupies the assembly line station, and secondly complicates the process, making the control program more difficult and more prone to errors; for example, when the transfer mechanism transfers the workpiece into the shell, the prior art usually directly grasps it with a claw When putting the workpiece into the shell, the lack of positioning guidance of the profiling mechanism will lead to slow and inaccurate positioning in the shell. For example, when the crimping assembly mechanism is used for the crimping assembly of LN-level terminals of the socket, since the terminals are particularly easy to entangle, it is difficult to grab the terminals with the correct posture from the entangled terminals and put them into the workpiece processing flow, which will cause the entire process to be delayed. There are also problems with the shell entering the processing flow and automated detection problems. The above problems include more. When these problems appear in large-scale assembly line processing, the processing efficiency will be greatly reduced. Therefore, it is of great significance to improve the crimping assembly efficiency of the workpiece and improve the yield rate of the workpiece in the fully automatic crimping assembly mechanism by solving the problems in the above links.

[0050] like Figure 3 and Figure 4 As shown, the cache flipping mechanism 2 is located on one side of the conveyor line 1, and includes a flip cylinder 21 and a rotating platform 22. The rotating platform 22 is arranged on the flip cylinder 21 and rotates with the flip cylinder 21. A flip fixing frame 23 is provided below the flip cylinder 21. A limiter 24 is provided on one side of the flip cylinder 21. A limiter block 25 is provided below the rotating platform 22 and cooperates with the limiter 24 to limit the flip cylinder 21 to rotate back and forth within 180° on the horizontal plane. A material receiving carrier 26 that can flip the workpiece is provided on the rotating platform 22. The material receiving carrier 26 can adjust the two workpieces to be assembled according to the state during assembly. Specifically, a hollow through hole 27 is provided on the material receiving carrier 26. The load-bearing part of the workpiece flips in the hollow through hole 27, and its posture is flipped to the posture to be assembled by its own weight.

[0051] The transfer robot 3 cooperates with the industrial camera to grab the workpiece with the correct posture and place it in the material receiving carrier 26 of the buffer flipping mechanism 2.

[0052] like Figure 5 and Figure 6The transfer and crimping mechanism 4 is arranged above the conveyor line 1, and includes a transfer and loading fixed frame 41 and a vertical connecting plate 42 of the conveyor line 1; a crimping mechanism 43 and a transfer mechanism 44 are respectively arranged on both sides of the vertical connecting plate 42; a horizontal guide rail is arranged on the transfer and loading fixed frame 41, and the horizontal guide rail is perpendicular to the conveyor line 1, and a driving module is also arranged on the transplanting fixed frame 41, and the driving module drives the crimping mechanism 43 and the transplanting mechanism 44 to be slidably connected to the guide rail; the crimping mechanism 43 includes a vertical driving cylinder 431 and a crimping end 432 which rises and falls with the vertical driving cylinder 431; the transfer mechanism 44 includes a transfer cylinder 441 and a transfer claw 442 which rises and falls with the transfer cylinder 441; specifically, slide rails are arranged on both sides of the vertical connecting plate 42, and the crimping end 432 and the transplanting claw 442 slide vertically on the slide rails.

[0053] In this embodiment, the transfer gripper 442 is fixedly connected to the numerical connection plate 42 via an equidistant connection plate 45, and performs lifting and lowering motion under the pneumatic stroke of the transfer cylinder 441; the crimping end 432 and the transfer gripper 442 are in the same horizontal plane.

[0054] When the transfer crimping mechanism 4 is working, the transfer clamp 442 clamps the workpiece on the buffer flipping mechanism 2 while the crimping end 432 crimps the workpiece on the conveyor line 1 .

[0055] In this embodiment, Fig. 9 In order to prevent the workpiece from being deformed or not being placed in place, a positioning and profiling mechanism 6 is provided below the transfer and crimping mechanism 4, including a profiling fixing frame 61 and a profiling positioning block 62.

The profiling positioning block 62 is located at the output end of the lifting cylinder and is slidably connected to the slide rail as the lifting cylinder moves up and down. The profiling positioning block 62 is made according to the shape of the workpiece. When placing the workpiece, the profiling positioning block 62 is driven by the lifting cylinder and simultaneously descends and presses the shell, so that the workpiece can be placed more accurately and quickly.

[0056] like Figure 7 and Figure 8 The fork mechanism 5 is arranged below the conveyor line 1, and includes a driving module 51 and a fork base 53 that drives the fork block 52 to perform linear motion under the drive of the driving module 51; below the fork base 53, a support plate 54 is fixedly provided on the bearing fixing frame 11, and a fork slider 55 is provided on the support plate 54 at intervals, and the fork slider 55 cooperates with a fork slide rail 56 provided on the lower end surface of the fork base 53 along the conveying direction, and a rotating rod 57 is connected to the output end of the driving module 51, and the rotating rod 57 is rotatably connected to a fixed seat 58 arranged below the support plate 54 through a bearing; the fork base 53 is transmission-connected to the rotating rod 57 through a connecting block 59,

[0057] When the driving module 51 drives the rotating rod 57 to rotate, the fork block 52 and the fork base 53 are slidably connected to the fork slider 55 under the transmission of the rotating rod 57, wherein the structure between the rotating rod 57 and the connecting block 59 can adopt a conventional screw structure in the art.

[0058] The fork block 52 is arranged at equal intervals on the fork base 53, and the fork block 52 includes a fork block base 521 and a push plate 522. One end of the push plate 522 is rotatably connected to the fork block base 521 through a rotating shaft 523, and the other end is connected to the fork block base 521 through a fork spring 524. The push plate 522 is at a certain angle to the fork block base 521. When the shell is located on the conveyor line 1, the shell and the fork block 52 are arranged at intervals, and the bottom of the shell is lower than the end of the push plate 522 close to the fork spring 524, and the bottom of the shell is higher than the end of the push plate 522 that is rotatably connected to the fork base 52.

[0059] The fork mechanism 5 is driven by the driving module 51, so that the push plate 522 pushes the shell to slide forward equidistantly to each working position. After the movement is completed, the driving module 51 drives the fork base 53 to move backward in a straight line, and the fork base 52 drives the fork block 52 to retreat. When retreating, due to the elastic force of the fork spring 524, the position of the shell on the conveyor line 1 is not affected.

[0060] A detection mechanism 7 after the workpiece crimping is completed is also provided on the side of the transfer crimping mechanism 4 in the conveying direction. Fig.10 , including a sensing element 71 arranged above the conveyor line 1, and the sensing element 71 is used to determine whether the workpiece is qualified. If it is qualified, the fork mechanism 5 will continue to transfer the workpiece to the next workstation. If there is a defect, the workpiece will be sent to an NG box arranged on one side of the conveyor line 1.

[0061] like Fig.11 A belt conveyor mechanism 8 is provided on the material inlet side of the fork mechanism 5, and the belt conveyor mechanism 8 includes an upper mounting plate and a belt conveyor slideway arranged under the upper mounting plate. The fork base 53 of the fork mechanism 5 extends to the bottom of the belt conveyor mechanism 8. When working, the fork base 53 is driven by the driving module 51, and the fork block 52 under the belt conveyor mechanism 8 will accurately shift the shell waiting on the belt conveyor mechanism 8 to the bottom of the transfer and pressing mechanism 4.

[0062] like Fig.12A spring stop assembly 81 is provided on the belt transmission mechanism 8 and at the intersection with the conveyor line 1 above the fork mechanism 5. The spring stop assembly 81 includes a fixed seat 811, a blocking structure and a spring 812.

The connecting block 814 is rotatably connected to the groove structure of the front half of the fixed seat 811 through a rotating shaft. The middle of the connecting block 814 is provided with upper and lower through holes, and the spring 812 is arranged in the through hole, and the upper and lower ends of the spring 812 are respectively fixed to the lower end of the tongue plate 813 and the lower end of the through hole, and the lower end of the blocking block 815 is arranged as an arc guide structure, which blocks the shell on the belt transmission slide.

[0063] When it is necessary to convey the shell, the fork block 52 is driven by the driving module 51, and the push plate 522 of the fork block 52 pushes the bottom of the shell, so that the shell acts on the arc guide structure of the blocking block 816. Under the thrust of the shell and the elastic force of the spring 812, the blocking structure is deformed to allow the shell to pass through, and then the spring 812 is reset, and the blocking block 815 continues to block the waiting shell.

[0064] In this embodiment, the workpiece used for processing is the socket LN terminal. Since the terminals are easily entangled on the feed tray, this embodiment separates the easily entangled terminals through a two-level feeding method, that is, feed vibration trays 9 are respectively provided on both sides of the transfer robot 3. The state of the terminal is adjusted by the vibration of the feed vibration tray 9. After the terminal state is judged by the industrial camera arranged on the feed vibration tray 9, the transfer robot 3 grabs the terminal judged correctly by the industrial camera and sends it to the cache flipping mechanism 2.

[0065] In the present embodiment, since the socket LN terminals are divided into L level and N level, corresponding to the L level and the N level, the present embodiment is provided with a cache rotating mechanism 2 corresponding to the L level and the N level, a positioning profiling mechanism 6 corresponding to the L level and the N level, a transfer and crimping mechanism 4 corresponding to the L level and the N level, two groups of transfer robots 3, two groups of L level feeding vibration disks 9, and two groups of N level feeding vibration disks 9.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
