[0002] In the production process of an electronic motherboard, it is necessary to side insert the terminals of electronic components into the corresponding interface positions on the motherboard. Most of the existing automated assembly devices are applied in the assembly line of an electronics factory. In the specific assembly process, after the material terminals are taken out of the magazine by an automated robotic arm, the material terminals are then assembled corresponding to the corresponding interfaces on the motherboard. However, when the initial positions of the material terminals are irregular, on the one hand, it is not convenient for the robotic arm to grip, and on the other hand, it will also cause inaccurate assembly when the robotic arm grips the material terminals and assembles them with the motherboard, thereby affecting the yield rate of the motherboard after assembly. A low-power multi-terminal side-insertion combined two-device provided by Chinese Patent CN201721469291.4 includes a main housing, and also includes a protector and a starter. The protector is a flat protector, and the protector is located above the starter. It also includes terminal jacks. The starter is provided with a first terminal jack and a second terminal jack, and the protector is provided with a third terminal jack; the main housing is provided with a receiving groove, and the side end of the protector is provided with a fixed insert for inserting into the receiving groove; it also includes a plurality of terminals. Its purpose is to provide a low-power multi-terminal side-insertion combined two-device with a simple structure and easy to implement. The structures of each component are improved so that the flat protector can be installed on the starter. In addition, the setting directions of each terminal are changed to the side, improving the operating space. However, it mainly improves the starter of the terminal, and still cannot effectively improve the assembly and installation of the motherboard and the material terminal, and still has the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a material terminal side insertion device and a side insertion method.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: A material terminal side insertion device includes an operation cabinet. A plurality of tray lifting mechanisms are arranged inside the operation cabinet. The tray lifting mechanisms are used to control the lifting of the trays in the magazine and lift the material terminals to the operation platform. A first robotic arm that can move in multiple directions is arranged in the operation cabinet. The first robotic arm grips the material terminals in the tray and places them on a first precise positioning tooling on one side. The first precise positioning tooling is used to position the material terminals;

[0005] On one side of the operation cabinet, a conveyor line is provided. At the lower end of the conveyor line, a liftable jig tooling is provided. At one end of the conveyor line, a second manipulator capable of multi-directional movement is fixed. The second manipulator is used to clamp the material terminal on the first fine positioning tooling into the slot of the jig tooling, and the jig tooling is lifted upward until the material terminal is inserted into the main board.

[0006] As a further description of the above technical solution, multiple groups of the first fine positioning toolings are arranged along the length direction of the operation cabinet, and the first fine positioning toolings are arranged between the conveyor line and the tray lifting mechanism.

[0007] As a further description of the above technical solution, detection cameras are fixed on both the first manipulator and the second manipulator, and the detection cameras are respectively used to take pictures and position the material terminals in the tray and the first fine positioning tooling.

[0010] As a further description of the above technical solution, the first fine positioning tooling includes three different types of positioning grooves and corresponding pressing clamping plates for accurately positioning three different types of material terminals.

[0011] A side insertion method for a material terminal side insertion device, the specific steps include:

[0012] S1, Loading materials from the material bin, and the tray lifting mechanism lifts the tray to the maximum height that the tray lifting mechanism can move;

[0013] S2, The first manipulator moves above the tray, and takes pictures and positions the material terminal to be grabbed through the detection camera;

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] A material terminal side-insertion device provided by an embodiment of the present application is mainly used for the automatic assembly of the main board in an electronic device and the terminals at corresponding positions on the main board, solving the problem that the existing side-insertion devices cannot be highly automated and accurately assemble the material terminals onto the main board. Compared with the prior art, it has a higher degree of automation and can effectively reduce the problem that the material terminals cannot be docked or the interfaces between the material terminals and the main board cannot be fully and effectively contacted during the assembly of the material terminals onto the main board due to the offset of the placement positions of the material terminals, resulting in the main board being unable to be used normally. To solve this problem, the technical concept of the present invention is to lift the tray out of the magazine through the tray lifting mechanism. At the same time of lifting, the tray will be filled with materials, but at this time, not all the materials are placed regularly. The first manipulator clamps the material terminal and places it into the first precise positioning tooling. The first precise positioning tooling can correct and position the position of the material terminal. Then, the second manipulator inserts the material terminal that has been corrected and positioned into the fixture tooling. After all the material terminals in the fixture tooling are filled, they are directly assembled with the corresponding interfaces on the main board at one time, which can achieve precise positioning and assembly while also improving the assembly efficiency. Compared with the existing method of inserting the material terminals into the main board one by one, the efficiency is higher. And compared with inserting the material terminals into the interfaces of the main board multiple times, it can effectively reduce the problem of the normal function of the main board caused by installation errors and can effectively improve the yield rate of the main board assembly.

[0036] Please refer to Figures 1 - 5 , in one embodiment: A material terminal side-inserting device includes an operation cabinet 1. Inside the operation cabinet 1, there are multiple tray lifting mechanisms 2. In this embodiment, there are three tray lifting mechanisms 2, and a tray is placed on the upper end of each tray lifting mechanism 2. The shape of the tray is roughly a square plate. Multiple slots for placing material terminals are distributed on the upper end of the square plate. During use, the tray lifting mechanism 2 is used to control the lifting of the tray in the magazine 3 and lift the material terminals to the operation platform. The operation platform refers to the highest position that the tray lifting mechanism 2 can reach. After the tray rises from the magazine 3, the tray contains multiple material terminals, and the material terminals in this state are not all arranged regularly. Inside the operation cabinet 1, there is a first manipulator 4 that can move in multiple directions. Specifically, the first manipulator 4 is a three-axis manipulator. At the fixed end of the first manipulator 4, an X-direction sliding track and a Y-direction sliding track fixed to the lower end of the operation cabinet 1 enable the entire first manipulator 4 to move along the length direction of the operation cabinet 1, i.e., the X direction, to pick up the material terminals in multiple trays on the other side. The first manipulator 4 grips the material terminals in the tray and places them on the first fine positioning tooling 5 on one side. The first fine positioning tooling 5 is used to position the material terminals. When the material terminals are picked up and assembled with the main board, they are first positioned by the first fine positioning tooling 5 to ensure the accuracy of the second manipulator 8 when picking up and placing, which can effectively reduce the accuracy problems caused by the deviation of the initial position of the material terminals during assembly, and further affect the usability rate after the connection between the main board and the material terminals;

[0037] On one side of the operation cabinet 1, there is a conveyor line 6. A liftable fixture tooling 7 is provided at the lower end of the conveyor line 6. One end of the conveyor line 6 is fixed with a second manipulator 8 that can move in multiple directions. The second manipulator 8 is also a three-axis manipulator. The second manipulator 8 is installed above the conveyor line 6 through a fixed frame. The second manipulator 8 is used to pick up the material terminals on the first fine positioning tooling 5 and place them in the slots of the fixture tooling 7. The fixture tooling 7 rises upward until the material terminals are inserted into the main board, and then the second manipulator 8 inserts the material terminals into all the slots of the lower fixture tooling 7. The slots of the fixture tooling 7 correspond to the installation end of the main board. Therefore, the material terminals required for the main board can be inserted into the corresponding positions of the main board at one time. Compared with the prior art of installing single material terminals on the main board multiple times, inserting the material terminals into the main board at one time can effectively reduce the error generated during insertion and effectively improve the yield rate of the main board installation.

[0038] Further, detection cameras are fixed on both the first manipulator 4 and the second manipulator 8. The detection cameras are respectively used to take pictures and position the material terminals in the tray and the first fine positioning tooling 5, and the position data is transmitted to the control system that controls the first manipulator 4 and the second manipulator 8, so as to control the first manipulator 4 and the second manipulator 8 to accurately place the material terminals with jigs.

[0039] Further, a lower detection mechanism is provided at the end of the conveyor line 6. The lower detection mechanism includes a lower detection camera 91 and a corresponding light source 92. After the main board and the material terminals are assembled, before the assembled main board is unloaded through the conveyor line 6, the lower detection camera 91 can detect the assembled main board, and can classify defective main boards and well-assembled main boards.

[0040] The first fine positioning tooling 5 will be described. The first fine positioning tooling 5 includes a positioning groove 501. A pressing clamping plate 502 is movably arranged on one side of the positioning groove 501. The outside of the pressing clamping plate 502 is movably connected to a driving cylinder 503. After the material terminal is placed in the positioning groove 501, the driving cylinder 503 controls the movement of the pressing clamping plate 502 to push the material terminal, so that the material terminal can fit the positioning groove, thereby realizing the deviation correction of the material terminal to ensure the accurate installation of the subsequent material terminal.

[0041] To facilitate the understanding of the above technical solutions of the present invention, the following will describe in detail the specific implementation steps or operation methods of the present invention in the actual process:

[0042] A side insertion method for a material terminal side insertion device, the specific steps include:

[0043] S1, feeding from the material bin, and the tray lifting mechanism lifts the tray to the maximum height that the tray lifting mechanism can move;

[0044] S2, the first manipulator moves above the tray, and takes pictures and positions the material terminal to be grabbed through the detection camera;

[0045] S3, the first manipulator receives the position information data detected by the detection camera, grabs the material terminal into the first fine positioning tooling for deviation correction positioning. The specific method for deviation correction positioning of the material terminal is:

[0046] The detection camera on the first manipulator detects the type of the material terminal, and places the material terminal into the corresponding first fine positioning tooling. The driving cylinder of the first fine positioning tooling drives the pressing clamping plate to make the material terminal fit the inner wall of the positioning groove.

[0047] S4, the second manipulator grabs the material terminal on the first fine positioning tooling into the placement groove of the jig tooling;

[0048] S5. Repeat the above steps until all the placement slots of the jig and tooling are filled with material terminals;

[0049] S6. After the conveyor line detects the entry of the main board, the conveyor line 6 is an SMT conveyor line. The lifting mechanism under the jig and tooling lifts the main board, and the cylinder on the jig and tooling inserts the material terminals into the corresponding positions of the main board;

[0050] S7. The detection camera on the second robot takes pictures of the corresponding insertion positions on the main board for detection;

[0051] S8. If the detection is passed, the lifting mechanism descends, and the main board passes along the conveyor line, completing the main board plug-in process. Before the main board plug-in process is completed, the main board reaches the lower detection mechanism, and the lower detection camera in the lower detection mechanism takes pictures of the main board for detection.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
