Description

Technical Field

[0001] This utility model relates to the field of coil processing equipment, and in particular to an automatic terminal insertion mechanism for a bobbin. Background Technology

[0002] Most coils consist of a wound frame, and some frames require two terminals to be inserted as external ports for the coil.

[0003] Currently, the insertion of skeleton terminals is done manually. After the terminal is inserted, the excess part of the terminal needs to be trimmed off. Then the insertion depth and electrical connection performance of the terminal are checked. Most of these processes are carried out on a production line with multiple manual operation stations, resulting in low overall efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic terminal insertion mechanism for a skeleton, which can automate the skeleton material picking, terminal insertion, trimming, inspection and unloading operations, thereby improving the overall assembly efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic terminal insertion mechanism for a skeleton, including a frame, an assembly turntable structure on the frame, a loading device for loading skeletons arranged in a ring on the assembly turntable structure, and an assembly material picking device, two terminal insertion devices, a terminal trimming device, a terminal insertion depth detection device for detecting the terminal insertion depth, a terminal electrical performance detection device for detecting the terminal electrical connection performance, and a feeding device, arranged sequentially along the rotation direction of the assembly turntable structure on the frame.

[0006] Preferably, the assembly loading device includes a loading plate with a central opening, and two turntable loading blocks that can move linearly are provided on the loading plate. The turntable loading blocks are provided with locking holes that are consistent with their moving direction. Locking springs are provided in the locking holes. The frame is provided with a top-opening structure that cooperates with the turntable loading blocks of the assembly material picking and unloading station.

[0007] Preferably, the top-opening structure includes a top-opening seat mounted on the frame, a top-opening lifting cylinder mounted on the top-opening seat, a top-opening lifting block connected to the top-opening lifting cylinder, a top-opening block mounted on the top-opening lifting block, and two top blocks on the top-opening block having inclined surfaces at the top and cooperating with the turntable material loading block.

[0008] Preferably, the unloading device includes an unloading movable structure mounted on the frame and having three-axis motion. The unloading movable structure is connected to an unloading clamp. The unloading device also includes an unloading conveying structure mounted on the frame. The unloading conveying structure includes an unloading conveying seat, on which a good product conveyor belt and a defective product storage trough are provided.

[0009] Preferably, the defective product storage tank has two tanks, which are used to load skeletons with unqualified insertion depth and unqualified electrical properties, respectively. The unloading conveyor seat is equipped with a defective product conversion cylinder that can adjust the position of the tanks on the defective product storage tank. The side of the defective product storage tank is also equipped with a defective product pushing cylinder, which is connected to a defective product pushing block. The defective product pushing block has a slot that mates with the tank wall between the two tanks.

[0010] Preferably, the terminal insertion device includes a terminal strip roll, a terminal strip conveying structure, and a terminal insertion seat. The terminal insertion seat has a terminal conveying groove. The terminal strip conveying structure is used to feed the terminal strip on the terminal strip roll into the terminal conveying groove and out of the terminal conveying groove.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0021] like Figure 1-3 As shown, this utility model is an automatic terminal insertion mechanism for a skeleton, including a frame 1. An assembly turntable structure 52 is mounted on the frame 1. A loading device for loading the skeleton 2 is arranged in a ring on the assembly turntable structure 52. Along the rotation direction of the assembly turntable structure 52, the frame 1 is sequentially equipped with an assembly material handling device 53 that cooperates with the loading device or the skeleton on it, two terminal insertion devices 54, a terminal trimming device 55, a terminal insertion depth detection device 56 for detecting the terminal insertion depth, a terminal electrical performance detection device 57 for detecting the terminal's electrical connection performance, and a feeding device 58. The loading device includes a centrally located opening. The machine tool plate has two turntable loading blocks 69 that can move linearly. The turntable loading blocks 69 have locking holes 70 that are aligned with their moving direction. Locking springs are installed in the locking holes 70. The frame 1 is equipped with a top-opening structure 62 that cooperates with the turntable loading blocks 69 at the assembly material picking and unloading station. The top-opening structure 62 includes a top-opening seat 63 on the frame 1. A top-opening lifting cylinder 66 is installed on the top-opening seat 65. The top-opening lifting cylinder 66 is connected to a top-opening lifting block 67. A top-opening block 68 is installed on the top-opening lifting block 67. The top-opening block has two top blocks with inclined surfaces at the top that cooperate with the turntable loading blocks 69.

[0022] In practical applications, it is used in conjunction with a conveying structure for transporting the wound skeleton. First, the top-opening structure 62 of the turntable loading station operates. Specifically, the top-opening lifting cylinder 66 raises the top-opening lifting block 67, which in turn raises the top-opening block 68. This causes the two turntable loading blocks 69 to move in opposite directions via the inclined surfaces of the two top blocks, compressing the block springs and opening the assembly loading device. Then, the assembly picking device 53 picks up the skeleton from the conveying structure and places it onto the assembly loading device at the turntable loading station. After loading, the top-opening structure 62 returns to its original position. Finally, the turntable assembly structure 52 rotates, moving the assembly loading device containing the skeleton to the terminal insertion device. At position 54, a single terminal is inserted. Then, the turntable continues to rotate, moving to the second terminal insertion station to insert the second terminal. It then continues to rotate, moving to the terminal trimming station, where the terminal is trimmed by the terminal trimming device. After that, it continues to rotate to the terminal insertion depth detection device 56 to detect the terminal insertion depth (using a distance measuring structure). Then, it continues to rotate to the terminal electrical testing device 57 for electrical testing (using a liftable test pen). After that, it moves to the unloading station, where the loading fixture is opened again by the top opening structure 62. Finally, the frame 20 is removed by the unloading device 58, thus completing the integrated continuous operation of terminal insertion, trimming, testing, and unloading of the frame.

[0023] like Figure 2 and Figure 4 As shown, the feeding device 58 includes a feeding movable structure 59 mounted on the frame 1 and having three-axis motion. The feeding movable structure 59 is connected to a feeding clamp 60. The feeding device 58 also includes a feeding conveying structure 61 mounted on the frame 1. The feeding conveying structure 61 includes a feeding conveying seat 71. The feeding conveying seat 71 is provided with a good product conveyor belt 72 and a defective product storage tank 73. The defective product storage tank 73 has two tanks, which are used to load skeletons with unqualified insertion depth and unqualified electrical properties, respectively. The feeding conveying seat 71 is provided with a defective product conversion cylinder 74 that can adjust the position of the tanks on the defective product storage tank 73. The side of the defective product storage tank 73 is also provided with a defective product pushing cylinder 75. The defective product pushing cylinder 75 is connected to a defective product push block 76, and the defective product push block 76 has a slot that cooperates with the tank wall between the two tanks.

[0024] The specific unloading operation is as follows: Based on the detection results of the terminal insertion depth detection device 56 and the terminal electrical properties detection device 57, after the skeleton 20 has been inspected, it enters the unloading station. After the assembly loading device is opened by the opening structure 62, the unloading movable structure 59 drives the unloading clamp 60 to perform three-axis (XYZ) motion, clamping the skeleton 20 on the assembly loading device and moving it to the good product conveyor belt 72 or the defective product storage tank 73. The defective product storage tank 73 contains two tanks, used to hold skeletons with unqualified insertion depth and unqualified electrical properties, respectively. First, according to the detected structure, the defective product conversion cylinder 74 moves the corresponding tank to the position of the unloading clamp 60 to place the defective skeleton. This allows good products to be placed on the good product conveyor belt 72 and transported away, while defective products enter the corresponding tank in the defective product storage tank 73. Then, the defective product pushing cylinder 75 drives the defective product pusher 76 to move, moving the defective skeleton to make room for the next defective skeleton.

[0025] like Figure 5 As shown, the terminal insertion device 54 includes a terminal tape roll, a terminal tape conveying structure 86, and a terminal insertion seat 81. The terminal insertion seat 81 is provided with a terminal conveying groove 85. The terminal tape conveying structure 86 is used to feed the terminal tape on the terminal tape roll into the terminal conveying groove 85 and out of the terminal conveying groove 85. The terminal insertion seat 81 is provided with a terminal insertion cylinder 82. The terminal insertion cylinder 82 is connected to a terminal insertion pressure plate 83. The terminal insertion pressure plate 83 is connected to a terminal insertion pressure block 84 that inserts a single terminal that exceeds the terminal conveying groove 85 into the frame 20.

[0026] The specific operation of terminal insertion is as follows: First, the end of the terminal tape roll is manually pulled out and the terminal tape passes through the terminal tape conveyor structure 86. Then, the terminal tape can be moved by the terminal tape conveyor structure 86, so that its end part enters the terminal conveyor groove 85 and the first terminal exceeds the terminal conveyor groove 85. Then, the terminal insertion cylinder 85 drives the terminal insertion pressure plate 83 and the terminal insertion pressure block 84 to descend, so that the terminal insertion pressure block 84 presses the terminal that exceeds the terminal conveyor groove 85 into the skeleton 20. The terminal conveyor groove 85 can limit the terminal insertion pressure plate 83 to avoid excessive pressing and damage to the skeleton 20.

[0027] like Figure 6 As shown, the terminal trimming device 55 includes a trimming seat 91 mounted on the frame 1. The trimming seat 91 is equipped with a trimming lifting cylinder 92 and a trimming limiting block 94. The trimming lifting cylinder 92 is connected to a trimming scissors 93 that can pass through the middle of the trimming limiting block 94.

[0028] The trimming operation is as follows: The trimming lifting cylinder 92 drives the trimming scissors 93 to descend, thereby allowing the trimming scissors 93 to pass through the trimming limit block 94, ensuring that the trimming scissors do not deviate during lifting and lowering, and ensuring a good trimming effect. At the same time, the trimming limit block 94 can also limit the tip of the trimming scissors to prevent the trimming scissors from descending too far and damaging the frame 20.
