Description

Technical Field

[0001] This utility model relates to the field of terminal riveting technology, specifically a novel terminal riveting device. Background Technology

[0002] In the field of shaded-pole motor component manufacturing, it is necessary to rivet the terminals into the frame. The ordinary manual terminal insertion process mainly includes the insertion of the split terminal into the frame body and the terminal riveting process.

[0003] This traditional method of manually inserting terminals into the skeleton relies on manual operation, which is relatively slow and labor-intensive, often causing fatigue. It often has the following effects during skeleton assembly production: First, the terminals are designed to have four different ports in the skeleton slots. Since the skeletons look roughly the same, it is very easy to insert the terminals into the wrong holes, causing unnecessary quality problems and rework. Second, the skeleton ports and terminals are interference fit, and insertion requires a certain amount of force. Since each person's strength is different, the exposed length of the terminals is uneven, which reduces the quality of terminal riveting.

[0004] Therefore, this utility model proposes a novel terminal riveting device. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a novel terminal riveting device, comprising:

[0021] Workbench 1 has a terminal feeder 2 and a terminal robot 3 on top for feeding and inserting terminals. A skeleton feeder 4 is located on the side of workbench 1 for feeding workpiece skeletons. A conveyor 5 is located above workbench 1 for conveying workpiece skeletons. The conveyor 5 is intermittently controlled by a program and is fixedly connected to workbench 1 via multiple supports. A detection mechanism 6 is located on the side of the conveyor 5 to detect the orientation of the skeleton. A riveting mechanism 7 is also located on the side of the conveyor 5 to insert terminals into the skeleton. The detection mechanism 6 can monitor the skeleton in real time during the conveying process and automatically reject incorrect skeletons, reducing the occurrence of incorrect terminal insertion. Simultaneously, the riveting mechanism 7 ensures that multiple terminals are riveted to the skeleton simultaneously and that the riveting depth is the same, ensuring good riveting quality between the terminals and the skeleton.

[0022] The detection mechanism 6 includes a fixing block 8 located on the side of the conveying channel 5. The side of the fixing block 8 is fixedly connected to the conveying channel 5. A connecting rod 9 is provided on the side of the fixing block 8 and fixedly connected thereto. A vision detector 10 is provided at the bottom of the connecting rod 9 and fixedly connected thereto. An electric push rod 11 is provided inside the fixing block 8 and fixedly connected thereto. The ejection part of the electric push rod 11 is located inside the conveying channel 5 and contacts the side of the skeleton. The ejection area of ​​the electric push rod 11 can slide freely inside the conveying channel 5. The vision detector 10 is electrically connected to the electric push rod 11. When the vision detector 10 detects that the skeleton orientation is inconsistent, the electric push rod 11 automatically starts and pushes the skeleton out of the conveying channel 5, promptly reminding the staff to replace or correct it, facilitating subsequent riveting and improving the accuracy of terminal riveting.

[0023] The riveting mechanism 7 includes a fixed box 12 located on the side of the conveying channel 5. The side of the fixed box 12 is fixedly connected to the conveying channel 5. The fixed box 12 has a connecting plate 13 inside and is slidably connected to it. The side of the connecting plate 13 has an electric cylinder 14 and is fixedly connected to it. The electric cylinder 14 is fixedly connected to the fixed box 12 through a bracket. The other side of the connecting plate 13 has a slider 15 and is fixedly connected to it. The side of the slider 15 is clamped with two terminals to be riveted. (The terminals are automatically picked up from the terminal feeder 2 by the terminal robot 3 and clamped to the side of the slider 15, which is the prior art.) The terminals are aligned with the port of the skeleton. The slider 15 is located inside the conveying channel 5 and is slidably connected to it. The preset pushing distance of the electric cylinder 14 can ensure that the two terminals are inserted into the skeleton at the same distance, reducing the phenomenon of uneven terminal insertion.

[0024] Furthermore, the side of the connecting plate 13 is provided with a sliding column 16 and fixedly connected thereto. The sliding column 16 is located in the conveying channel 5 and slidably connected thereto. The sliding column 16 is elastic and can only shrink slightly in the longitudinal direction. The end of the sliding column 16 is provided with a detection piece 17 and fixedly connected thereto. The upper part of the fixing box 12 is provided with a lamp body 18 and fixedly connected thereto. The detection piece 17 is electrically connected to the lamp body 18. When the side of the detection piece 17 is in contact with the end of a single terminal, the lamp body 18 is automatically turned on. When the side of the detection piece 17 is in contact with the ends of two terminals at the same time, the lamp body 18 is in the off state. The operator can judge whether the riveted terminals are at the same extension distance by the state of the lamp body 18, thereby further ensuring the quality of riveting.

[0025] Working principle:

[0026] After the skeleton enters the conveyor channel 5, the skeleton will first be monitored by the detection mechanism 6. When the vision sensor detects that the skeleton is not placed accurately, the electric push rod 11 will automatically start and push out a preset distance to push the unqualified skeleton in the conveyor channel 5 out of its interior, reminding the staff to replace or adjust it in time, ensuring the accuracy of subsequent terminal riveting and reducing the possibility of incorrect terminal insertion.

[0027] Next, when the skeleton moves to the front of the slider 15, the electric cylinder 14 starts and extends a preset distance, causing the connecting plate 13 to simultaneously insert the two terminals at the end of the slider 15 into the port of the skeleton, ensuring that they have the same riveting pressure and improving the riveting accuracy. Subsequently, the riveted skeleton will continue to be pushed by the conveyor channel 5 until its terminal part moves to the front of the detection plate 17. At this time, the retracted cylinder will push out again to the same distance as before. The connecting plate 13 will drive the sides of the slider 16 and the detection plate 17 to move closer to the ends of the two terminals. If the lamp body 18 is not lit, it means that the two terminals are in the same horizontal state. If the nail body is lit, it means that the ends of the two terminals are at different extension lengths. At this time, the staff can be reminded to reject or correct the unqualified formed skeleton to ensure that the riveted skeleton workpiece has excellent quality.
