[0033] A four-axis robot 5 and a terminal buckle machine 6 are arranged on the frame 1 on the side of the wire conveyor belt conveyor 2. The four-axis robot and the terminal buckle machine 6 are respectively connected to the control host 4a by circuits, and their actions are controlled by the control host.

A control cabinet is arranged on the side of the frame, and the wire conveyor belt conveyor and the carrier moving platform are respectively connected to the control cabinet. In the present invention, the control cabinet and the connection and control methods between it and each mechanism are all prior arts, belonging to the common knowledge in the field, and are not the technical solutions claimed to be protected by the present invention, and will not be repeated here.

[0034] In this embodiment, the four-axis robot and the terminal buckle machine are both prior art. The four-axis robot is a robot model AH-6530-054 produced by Dongguan Liqun Automation Technology Co., Ltd. The terminal buckle machine is a 802 ultra-quiet terminal machine produced by Lechang Tongchang Electronics Co., Ltd.

[0035] A wire clamping mechanism 9 is connected to the free end of the Z-axis screw of the four-axis robot 5. The wire clamping mechanism 9 consists of a pneumatic finger 9a fixed to the lower end of the Z-axis screw and two L-shaped clamping blocks 9b arranged on the pneumatic finger 9a to match each other; the two L-shaped clamping blocks 9b cooperate to clamp the wire.

[0036] The wire clamping mechanism 9, the four-axis robot 5, the two-dimensional vision camera 3 and the vision control unit 4 cooperate to clamp and convey the wire on the wire conveyor belt 2 to the stator fixture 8, and then fit it with the stator coil wire end on the stator fixture 8 and move it into the head of the terminal buckling machine 6 for automatic buckling.

[0037] Preferably, in order to avoid the influence of light on the imaging of the wires on the wire conveyor belt conveyor and ensure the accuracy of the imaging of the two-dimensional visual camera, a light shield 1a is provided on the frame 1 on the upper periphery of the wire conveyor belt conveyor 2, and the two-dimensional visual camera 3 is opposite to the discharge end of the wire conveyor belt conveyor 2.

[0038] In this embodiment, the stator fixture 8 is composed of a base plate 8a, a transverse fixing block 8b with a groove-shaped structure arranged in the middle of the base plate 8a and adapted to the stator to be processed, vertical fixing blocks 8c respectively arranged at the openings on both sides of the transverse fixing block 8b, four L-shaped support frames 8d arranged at the edge of the base plate 8a and corresponding to the four stator coil ends on the stator, and an elastic positioning clip 8e arranged on each L-shaped support frame 8d and matched with the stator coil ends; positioning notches 8f are formed at the two end portions of the base plate 8a corresponding to the outer side of the transverse fixing block 8b; the positioning notches are used for precise positioning of the stator fixture when it moves on a conveying mechanism such as a carrier moving platform.

[0039] The elastic positioning clamp 8e is composed of an L-shaped fixed clamp block 8g which is vertically fixed on the L-shaped support frame 8d, guide positioning screws 8h which are vertically spaced and penetrated on the fixed clamp block 8g, an active clamp block 8i which is movably mounted on each guide positioning screw 8h and cooperates with the fixed clamp block 8g, and a compression spring 8j which is mounted on the screw between the outer wall of the active clamp block 8i and the nut of the guide positioning screw 8h.

[0040] The upper ends of the fixed clamp block 8g and the movable clamp block 8i are provided with mutually matching clamping notches 8k, and the upper ends of each clamping notch 8k are formed with a guide slope 8l, and the two clamping notches 8k cooperate with each other through the guide positioning screw 8h and the clamping spring 8j to form an elastic clamping opening. In the initial state, the stator coil wire end is located in the elastic clamping opening, and the width of the elastic clamping opening is smaller than the outer diameter of the wire, which is convenient for the overall positioning of the wire and the coil wire end after buckling and joining, ensuring that the wire and the wire end will not fall off and shift, and facilitating the processing of subsequent stations.

[0041] Furthermore, in order to improve the automation degree of the equipment and the processing efficiency, a matching carrier belt conveyor 10 is provided on the side of the carrier moving platform 7, and a plurality of stator jigs 8 with built-in stators are placed on the carrier belt conveyor 10, and the stator jigs 8 are transported to the carrier moving platform 7 through the carrier belt conveyor 10;

[0042] A first positioning mechanism 11 is provided at the output end of the carrier belt conveyor 10, and the first positioning mechanism 11 is composed of a first mounting plate 11a fixed on the frame of the carrier belt conveyor 10, a first double-rod cylinder 11b vertically fixed on one side of the first mounting plate 11a, a first blocking block 11c provided at the free end of the piston rod of the first double-rod cylinder 11b and matched with the stator fixture 8, a first photoelectric switch 11d provided on the other side of the first mounting plate 11a and located in front of the first blocking block 11c, and a second photoelectric switch 11e provided on the first mounting plate 11a on the side of the first photoelectric switch 11d and located behind the first blocking block 11c; the stator fixture 8 at the output end of the carrier belt conveyor 10 is positioned by the first positioning mechanism 11. Specifically, the first blocking block cooperates with the positioning notch on the stator fixture to achieve the positioning of the stator fixture. In the initial state, the first double-rod cylinder is in an extended state, and the first blocking block is higher than the upper conveying surface of the carrier belt conveyor. When the stator jig reaches the output end of the carrier belt conveyor, the first blocking block cooperates with the positioning notch to stop the stator jig from moving. At this time, the carrier belt conveyor is still in a rotating state, and the stator jigs are arranged one by one. The function of the first photoelectric switch is to detect whether there is a stator jig on the carrier belt as above, so as to control the work of the subsequent workstations. When the subsequent workstation requires workpiece processing, a signal is given through the control cabinet to lower the first double-rod rod, and the stator jig at the front end moves forward and enters the carrier moving platform. When the stator jig switches to the second photoelectric switch, the first blocking block is located in the positioning notch at the rear end of the stator jig. At this time, the second photoelectric switch gives a signal to control the first double-rod cylinder to rise, blocking the stator jig behind from moving forward. Thereby achieving the purpose of conveying a single stator jig at a time.

[0043] Preferably, the carrier mobile platform 7 includes a bracket 7a, a two-dimensional mobile platform 7b is arranged on the bracket 7a, a 180° rotary cylinder 7c is arranged on the two-dimensional mobile platform 7b, the 180° rotary cylinder 7c is connected to a conveying bracket 7e through a rotating connector 7d, a synchronous belt conveying mechanism 12 is arranged on the conveying bracket 7e, and a second positioning mechanism 13 cooperating with the stator fixture 8 is respectively arranged at the input end and the output end of the synchronous belt conveying mechanism 12; the stator coil wire head in the stator fixture 8 located on the synchronous belt conveying mechanism 12 is sent to the terminal buckle machine 6 head through the two-dimensional mobile platform 7b. The input and output functions of the stator fixture are realized through the synchronous belt conveying mechanism. The two-dimensional mobile platform is used to control the two-dimensional movement of the stator fixture, so as to achieve the purpose of moving forward to the terminal buckle machine head to buckle one of the coil wire heads at one end with the wire, and then moving sideways to buckle the other coil wire head and the wire on the same side.

[0044] The stator fixture is rotated 180° by a 180° rotating cylinder, and the two coil wire ends and the wires at the other end are buckled and joined. The specific buckling process is also controlled by the two-dimensional mobile platform.

[0045] Specifically, in this embodiment, the synchronous belt conveying mechanism 12 includes two sets of driven synchronous pulley groups 12a arranged in parallel and at intervals at the upper end of the conveying bracket 7e, and the driven synchronous pulley group 12a is composed of two driven synchronous pulleys 12b arranged at intervals and a driven synchronous belt 12c wound around the two driven synchronous pulleys 12b.

[0046] An active synchronous pulley mechanism 12d is arranged in the conveying bracket 7e below the two sets of driven synchronous pulley groups 12a, and the active synchronous pulley mechanism 12d is composed of a mounting frame 12e fixed to the bottom of the conveying bracket 7e, a rotating shaft 12f rotatably arranged on the mounting frame 12e through a bearing in the horizontal direction, a stepping motor 12g arranged on the conveying bracket 7e on the side of the rotating shaft 12f, and active synchronous pulleys 12h arranged at both ends of the rotating shaft 12f and respectively opposite to the two sets of driven synchronous pulley groups 12a;

[0047] The rotating shaft 12f is connected to the stepping motor 12g through a synchronous pulley and a synchronous belt; each driven synchronous belt 12c is connected to the driving synchronous pulley 12h below.

[0048] Further preferably, the second positioning mechanism 13 is composed of a second double-rod cylinder 13a vertically arranged on the conveying bracket 7e, a second blocking block 13b arranged at the free end of the piston rod of the second double-rod cylinder 13a and cooperating with the stator fixture 8, and an induction switch 13c arranged on the conveying bracket 7e and cooperating with the stator fixture 8; when the second double-rod cylinder 13a is in a retracted state, the upper end surface of the second blocking block 13b is located below the conveying surface of the synchronous belt conveying mechanism 12. When the stator fixture enters the synchronous belt conveying mechanism and is sensed by the induction switch at the input end, the second blocking block at the output end rises, and the stator fixture continues to move forward until it contacts the second blocking block at the output end and stops, and at the same time triggers the induction switch at the output end. At this time, the second blocking block at the input end rises, thereby completing the clamping and positioning of the stator fixture, ensuring that the stator fixture remains stationary during the entire processing process, and avoiding horizontal displacement that affects alignment and processing.

[0049] During work, workers arrange the wires at intervals on the wire conveyor belt conveyor. At the same time, the stator is placed on the stator fixture, and the wire ends are arranged and placed in each elastic clamp. The stator fixture is then placed on the carrier belt conveyor. Then the control cabinet is started to put the equipment into working state. The carrier belt conveyor sends the stator fixture to the carrier mobile platform, and one of the wire ends on the stator fixture is inserted into the terminal buckle machine head through the two-dimensional mobile platform and the 180° rotating cylinder.

[0050] At the same time, with the cooperation of the control host and the two-dimensional vision camera, the four-axis robot clamps the wire on the wire conveyor belt through the wire clamping mechanism and sends the wire into the terminal buckle machine head along a predetermined motion trajectory, while making the wire fit and clamped in the elastic clamp at the processing position.

[0051] After the four-axis robot moves into position, the wire clamping mechanism releases the wire, the control host controls the terminal buckle machine to work, and the four-axis robot resets. After the buckle is completed, the two-dimensional mobile platform moves the other wire end on the same side into the buckle machine head, and the four-axis robot repeats the above action to clamp another wire and send it into the terminal buckle machine for buckle connection.

[0052] Then the 180° rotary cylinder controls the stator fixture to rotate 180°, and the above steps are repeated to complete the buckling and joining of the wire ends and the conductors. At this point, the buckling and joining of the wire ends and the conductors of a stator coil are completed, and the stator fixture is sent out through the synchronous belt conveyor mechanism. The carrier belt conveyor then sends in the next stator fixture for buckling and joining.

[0053] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the description of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
