Detailed Implementation
[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please refer to Figure 1-6 ;
[0026] This utility model aims to simplify the structure of the insertion machine to meet the needs of small-batch orders. Specifically, it includes a transfer device 1 for moving the rotor body 91. The transfer device 1 shuttles between the loading device 2, the rotating fixture 3, and the unloading device 4. The rotating fixture 3 is connected to the translation component 5, which drives the rotating fixture 3 to move to the corresponding position of the insertion device 6. The output end of the insertion device 6 is connected to the conveying device 7. In order to further save equipment costs, both the loading device 2 and the unloading device 4 in this embodiment use conveyor belts to transport the rotor body 91.
[0027] During operation, the rotor body 91 is placed on the feeding device 2 in sequence, and then the transfer device 1 clamps one rotor body 91 from the feeding device 2. Preferably, since the rotor bodies 91 of different batches have different volumes, the transfer device may not be able to clamp the rotor body 91. Therefore, a vision camera can be installed on the transfer device 1 to obtain the current position of the rotor body 91. After the transfer device 1 obtains the rotor body 91, it places it in the rotating fixture 3, and then the translation component 5 sends the rotating fixture 3 to the position corresponding to the insertion device 6.
[0028] The rotary fixture 3 includes a movable seat 31, which is connected to a translation component 5. The translation component 5 consists of a sliding pair and a cylinder. A rotary seat 32 for fixing the rotor body 91 is rotatably connected to the movable seat 31. A servo motor 34 is installed at the bottom of the movable seat 31, and the output end of the servo motor 34 is connected to the rotary seat. The rotary seat 32 has a cylindrical protrusion 331 coaxially arranged with the rotor body 91 at its center, and limiting protrusions 332 are located on both sides of the cylindrical protrusion 331. After the rotor body 91 is placed into the rotary seat 32, the cylindrical protrusion 331 passes through the central through hole of the rotor body 91. The cylindrical protrusion 331 and the central through hole of the rotor body 91 are adapted to each other. At the same time, the limiting protrusions 332 also pass through other positions of the rotor body 91 to perform positioning and avoid problems such as rotational offset during insertion.
[0029] Then, the conveying device 7 outputs the terminal body 92 to the insertion device 6, and inserts the individual terminals into the holes of the rotor body 91 in sequence through the insertion device 6. At the same time, the servo motor 34 drives the rotating seat 32 to rotate intermittently, so that each hole on the rotor body 91 corresponds to the output terminal installed by the insertion device in sequence. That is, after the insertion of one hole of the rotor body 91 is completed, the rotor body 91 is rotated slightly by the precise angle control of the servo motor 34 so that the other hole corresponds to the output terminal installed by the insertion device, so as to complete the next insertion process.
[0030] After the insertion step is completed, the rotary fixture 3 is pushed out by the translation component 5, and then the rotor body 91 in the rotary fixture 3 is taken out by the transfer device 1 and placed in the unloading device 4. Preferably, a vision inspection device 8 is provided near the unloading device 4 to detect whether the rotor body 91 has missing terminals. The unloading device 4 may also include a collection box. Rotor bodies 91 with missing terminals are placed in the collection box, while good products are placed in the unloading device 4. Finally, another rotor body 91 is put into the rotary fixture 3 from the loading device 2 by the transfer device 1 to enter the next production process.
[0031] In order to simplify the overall structure of the equipment, this utility model can only perform insertion operations on one rotor body 91 at a time, but the insertion speed is very fast, which is sufficient to cope with small batch production orders. The overall cost is also very low. Moreover, due to the simple overall structure, the insertion production of rotor bodies 91 of the same type but different models only needs simple modifications to be put into production. It has strong scalability and wide applicability.
[0032] The rotor body 91 in this utility model is not a ring array type of insertion terminal, but only a part of it is required. Therefore, a sensing notch 35 is provided on the rotating seat 32, and a distance sensor 36 is installed on the movable seat 31. When the rotating seat 32 rotates a certain angle, the distance sensor 36 corresponds to the sensing notch 35, and sends a signal to remind the user to complete the insertion process of the current rotor body 91, and the servo motor 34 is reset.
[0033] One embodiment of the plug-in device 6 of this utility model specifically includes a bracket 61, on which a cylinder 62 is mounted longitudinally. A connecting block 631 is mounted on the output end of the cylinder 62. The connecting block 631 is slidably connected to the bracket 61 longitudinally. A connecting block 641 is provided below the connecting block 631. In this embodiment, the connecting block 641 can be fixedly connected to the bracket 61. The lower end of the connecting block 641 is as close as possible to the rotor body 91. That is, the gap between the lower end face of the connecting block 641 and the rotor body 91 should be less than the length of the terminal body 92. This is to prevent the terminal body 92 from coming out before entering the hole of the rotor body 91.
[0034] One side of the connecting block 2 641 has an insertion channel 642, which corresponds to the conveying device 7. A top pressure rod 632 passes through the insertion channel 642 and is connected to the connecting block 1 631. In this embodiment, the conveying device 7 adopts a vibratory feeder. A bridging assembly is connected to the output end of the vibratory feeder. The bridging assembly has a bridging channel for the terminal body 92 to move. The terminal body 92 enters the bridging channel in a vertical state. The insertion channel 642 is open, so the terminal body 92 can directly enter the insertion channel 642 after being output from the bridging channel. Then, the cylinder 1 62 pushes the connecting block 1 631 downward, and at the same time, it drives the top pressure rod 632 to move downward in the insertion channel 642, pushing the terminal body 92 into the hole of the rotor body 91. In addition, the output end of the conveying device 7 is close to the connecting block 2 641 and as close as possible to the rotor body 91 to prevent the terminal body 92 from sliding out of the empty position when it is withdrawn.
[0035] It should be noted that the position of the insertion channel 642 corresponding to the bridge channel in the initial state will be slightly larger, so that the terminal body 92 can enter smoothly. The terminal body 92 will deform and shrink slightly when the insertion channel 642 moves, but it will not affect its overall structure.
[0036] Furthermore, it also includes a driven block 651, which is slidably connected to the bracket 61, and a connecting block 641 is fixedly connected to the driven block 651. In this embodiment, the driven block 651 is located below the connecting block 631, and the same sliding pair is used on both sides. The connecting block 641 is located on one side of the driven block 651. A connecting rod 661 is provided between the driven block 651 and the connecting block 631. One end of the connecting rod 661 is connected to the driven block 651, and the other end passes through the connecting block 631. The connecting rod 661 is provided with a movable slot 662. The connecting block 631 is provided with a limiting part (not shown), which passes through the movable slot 662. The limiting part can be a bolt, etc. Preferably, a limiting notch 652 is provided on one side of the driven block 651, and a limiting block 653 is provided in the limiting notch 652. The limiting block 653 is fixedly connected to the bracket 61 and is used to limit the vertical movement range of the driven block 651.
[0037] Initially, under the action of connecting rod 661, driven block 651 is positioned away from rotor body 91. When operation is required, conveying device 7 inserts one terminal into insertion channel 642, then cylinder 62 extends to move connecting block 631 downwards. Simultaneously, driven block 651 also falls downwards under gravity. That is, connecting block 631, driven block 651, and connecting block 641 move downwards synchronously, while connecting block 641 and the end of conveying device 7 move in a staggered manner, allowing the lower end of connecting block 641 to be as close as possible to rotor body 91. During this process, the top... The pressure rod 632 is relatively stationary in the insertion channel 642 and does not contact the terminal body 92. When the driven block 651 moves downward a certain distance, it is blocked by the limiting block 653 and stops moving. However, the connecting block 631 continues to move downward. Under the action of the movable slot 662 and the limiting part, the connecting rod 661 passes into the connecting block 631, and the limiting part slides in the movable slot 662, so that the connecting block 631 can move relative to the driven block 651. At the same time, the pressure rod 632 slides in the insertion slot, pushing the terminal out of the insertion slot and into the rotor body 91.
[0038] This method reduces the sliding distance of the terminal body 92 in the insertion slot, avoids deformation of the terminal body 92 due to friction, and allows the lower end of the connecting block 641 to be as close as possible to the rotor body 91, resulting in more precise insertion.
[0039] In one embodiment of the present invention concerning a transfer device, the transfer device 1 includes a multi-axis moving assembly 11, which has at least two functions: translation and up / down. A double-headed cylinder 12 is installed at the movable end of the multi-axis moving assembly 11, and clamping arms 13 are installed at both ends of the double-headed cylinder 12. The inner side of the clamping arms 13 is provided with an arc-shaped notch 14, which can adapt to the shape of the rotor body 91 and better clamp it. The use of a double-headed cylinder as the clamping power is mainly due to its very low cost and low maintenance cost.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
