[0037] Referring to Figures 1-8 The preferred embodiment provided by the present application is shown.

[0038] The wire and ring automatic welding and coiling device is used for welding the wire 100 and the ring 102 to form a wire ring, and winding the wire ring on the wire coil 500. It comprises a wire pulling structure for pulling the wire 100 to move, a positioning shaft 101 for sleeving the ring 102 and positioning the head end of the wire 100, a welder 200 for welding and fixing the head end of the wire 100 and the positioning shaft 101 to form a wire ring, a wire coil 500 for winding the wire ring, and a moving clamp head for clamping the head end of the wire ring to connect the head end and the tail end of the wire ring on the wire coil 500.

[0039] After the head end of the wire ring is connected on the wire coil 500, the wire coil 500 rotates for a certain number of turns, and then the tail end of the wire ring is connected on the wire coil 500; the wire coil 500 is connected on the rotating table 504, and the rotating table 504 drives the wire coil 500 to rotate synchronously.

[0040] The wire and ring automatic welding and coiling device provided above pulls the wire 100 to move by the wire pulling structure, the head end of the wire 100 is placed on the positioning shaft 101, the ring 102 is sleeved on the positioning shaft 101, the welder 200 welds the head end of the wire 100 and the ring 102 to form a wire ring, the rotating table 504 drives the wire coil 500 to rotate synchronously, the head end of the wire ring and the tail end of the wire ring are connected on the wire coil 500, and the wire ring is wound on the wire coil 500, realizing automatic welding and coiling of the wire 100 and the ring, high manufacturing efficiency, and greatly reducing the manufacturing cost.

[0041] In actual manufacturing, the wire pulling structure is used to pull the wire 100 to move until the head end of the wire 100 is placed on the top of the positioning shaft 101, and the vacuum suction head of the ring is used to suck the circumferential side of the ring 102 to sleeve the ring 102 on the positioning shaft 101.

[0042] The inner side of the ring 102 has an inner circumferential wall, and the outer side of the ring 102 has an outer circumferential wall. The inner circumferential wall abuts against the head end of the wire 100 from top to bottom; at this time, the abutment between the head end of the wire 100 and the ring 102 is achieved, and the head end of the wire 100 is passed through the ring 102.

[0043] The head end of the wire 100 is welded and fixedly connected to the ring 102 using a welder 200, so that the wire 100 and the ring 102 form a wire loop; the pulling wire structure pulls the head end of the wire 100 to move a set distance, so that the ring 102 and the head end of the wire 100 are separated from the positioning shaft 101, and then the head end of the wire 100 is clamped and moved using a movable chuck.

[0044] In this embodiment, the automatic wire and ring welding and coiling equipment includes a wire reel 500 wound with wire 100 and releasing the wire through rotation, a guide wheel for guiding the wire transmission, and a cutter for cutting the wire 100 into a set length. When the wire reel 500 rotates a set number of times and the wire 100 in the wire loop reaches the set length, the cutter cuts the wire 100 from the loop to form the tail end of the wire 100.

[0045] In this embodiment, the automatic welding and coiling equipment of wire and ring includes a loading rack 400 on which a wire coil 500 is placed longitudinally. A longitudinal cavity 401 arranged longitudinally is provided in the loading rack 400. The top of the longitudinal cavity 401 has a loading top opening, and the bottom of the longitudinal cavity 401 has a loading bottom opening. A lower area is provided below the loading bottom opening, and a movable plate arranged for movement is inserted into the lower area.

[0046] The top of the movable plate has a accommodating groove and a flat area 402. When the wire drum 500 needs to be loaded, the movable plate is moved until the accommodating groove of the movable plate is located in the lower area and aligned with the bottom opening of the loading material. The wire drum 500 at the bottom of the longitudinal cavity 401 falls into the accommodating groove. Then, the movable plate is moved until the flat area 402 of the movable plate is located in the lower area, and abuts against the wire drum 500 from bottom to top to prevent the wire drum 500 in the longitudinal cavity 401 from falling. The vacuum suction cup of the wire drum 500 can then suck the wire drum 500 in the accommodating groove for loading.

[0047] In this embodiment, two clamping pieces are provided on the rotating platform 504. When the wire drum 500 is placed on the rotating platform 504, the two clamping pieces clamp the wire drum 500 toward each other, thereby fixing the wire drum 500 on the rotating platform 504. When the two clamping pieces swing away from each other, the wire drum 500 can be separated from the rotating platform 504. Of course, a single clamping piece can also be provided as long as the relative fixation between the wire drum 500 and the rotating platform 504 can be achieved.

[0048] In this embodiment, the outer circumference of the wire drum 500 has a circumferential groove 508 for winding the wire 100 . The circumferential groove 508 is arranged around the circumference of the wire drum 500 . The middle of the wire drum 500 has a groove 505 .

[0049] When the movable chuck clamps the head end of the wire 100 and moves it to the wire drum 500, and the head end of the wire 100 is fixedly connected to the wire drum 500, the ring 102 is placed in the groove 505, and the rotating table 504 drives the wire drum 500 to rotate synchronously, and the wire ring is wound in the circumferential groove 508 of the wire drum 500; when the wire drum 500 rotates a set number of times, the tail end of the wire 100 is fixedly connected to the wire drum 500, and the tail end of the wire 100 extends into the groove 505.

[0050] In this embodiment, the coiling station has a rotating table 504, and the wire coil 500 is sucked by the wire coil vacuum suction head 501, and the wire coil 500 is placed on the rotating table 504, and the wire coil 500 is relatively fixed to the rotating table 504; by setting the groove 505, before winding the wire loop, the ring 102 can be placed in the groove 505, and after winding the wire loop, the tail end of the wire 100 can be extended into the groove 505, thereby ensuring a better assembly relationship between the wire loop and the wire coil 500.

[0051] In this embodiment, the upper portion of the wire drum 500 has an upper annular wall surrounding the outer periphery of the groove 505. The upper annular wall is provided with two opposing partition grooves 506. The partition grooves 506 pass through the top of the upper annular wall to form a top opening. The partition grooves 506 are provided with a swinging clamping head 507. The partition grooves 506 also have a clamping wall 509 arranged toward the clamping head 507.

[0052] When the clamping head 507 swings away from the clamping wall 509, a clamping gap is formed between the clamping head 507 and the clamping wall 509. When the clamping head 507 swings toward the clamping wall 509, the clamping head 507 abuts against the clamping wall 509.

[0053] When the movable clamping head clamps the head end of the wire 100 and moves to above a partition groove 506 of the wire drum 500, the clamping head 507 in the partition groove 506 swings away from the clamping wall 509, and the head end of the wire loop enters the clamping gap from the top opening. After the wire loop is placed in the groove 505, the clamping head 507 swings toward the clamping wall 509 to clamp and fix the head end of the wire loop;

[0054] When the wire drum 500 rotates a set number of times and the wire 100 of the wire loop reaches a set length, the wire 100 of the wire loop is cut by a cutting knife to form the tail end of the wire loop.

[0055] After the mobile clamping head moves the tail end of the wire loop to above another partition groove 506 of the wire reel 500, the clamping head 507 in the partition groove 506 swings away from the clamping wall 509, and the tail end of the wire loop enters the clamping gap from the top opening. After the tail end of the wire loop extends into the groove 505, the clamping head 507 swings toward the clamping wall 509, clamping and fixing the tail end of the wire loop.

[0056] By setting two partition grooves 506 and setting a clamping head 507 in the partition groove 506, the clamping head 507 can form a clamping gap between the clamping head 507 and the clamping wall 509 through the swing of the clamping head 507, or abut against the clamping wall 509, so that the head end of the wire loop or the tail end of the wire loop can enter the clamping gap through the top opening, and the clamping head 507 can abut against the clamping wall 509 to achieve a fixed connection between the head end or the tail end of the wire loop.

[0057] In this embodiment, the wire and ring automatic welding and coiling equipment includes a blanking rack 300 , in which a strip-shaped storage tank 301 arranged tilted from top to bottom is provided, and a feed port is formed at the bottom of the storage tank 301 .

[0058] A plurality of swing heads 302 are provided around the feeding port. The inner ends of the swing heads 302 are hinged to the unloading rack 300. The outer ends of the swing heads 302 have abutting ends facing the feeding port. The swing heads 302 are connected to springs 303 that drive the swing heads 302 to swing toward the feeding port so that the abutting ends enter the feeding port.

[0059] When the wire reel with the wire loop wrapped around it passes through the feed port, the wire reel 500 squeezes the abutment end, driving the swing head 302 to swing away from the feed port, and the spring 303 is compressed until the abutment end deviates from the feed port. After the wire reel 500 passes through the feed port and is placed at the bottom of the storage tank 301, the compressed spring 303 drives the swing head 302 to swing toward the feed port until the abutment end swings into the feed port. The spring 303 is in a natural state, and the abutment end abuts against the wire reel 500 in the storage tank 301 from bottom to top, restricting the wire reel 500 in the storage tank 301 from passing downward through the feed port.

[0060] After the wire drum 500 passes through the feed port, multiple swing heads 302 are set, and the storage slot 301 is arranged at an angle. Under the restriction of the abutting end of the swing head 302, the wire drum 500 in the storage slot 301 will not detach from the storage drum downward through the feed port. The wire drum 500 enters the storage slot 301 through the bottom of the feed port. In the process of storing the wire drum 500 in the storage slot 301, since the storage slot 301 is arranged at an angle, the wire drum 500 can be automatically folded.

[0061] In this embodiment, a movable frame 502 is provided on the outer side of the unloading rack 300, and a rotating head 503 is provided on the movable frame 502, and a vacuum suction head 5031 is provided on the peripheral side of the rotating head 503; when the wire loop is wound around the wire drum 500, the movable frame 502 moves to the top of the rotating table, and the rotating head 503 rotates until the vacuum suction head 5031 sucks the wire drum 500 on the rotating table 504. Then, the movable frame 502 moves to the bottom of the unloading rack 300, and the rotating head 503 rotates, and moves the wire drum 500 sucked by the vacuum suction head 5031 toward the feed port.

[0062] In this embodiment, the top of the positioning shaft 101 has a linear groove 700, which is arranged along the axial extension of the positioning shaft 101; when the head end of the wire 100 is placed on the top of the positioning shaft 101, the lower part of the head end of the wire 100 is embedded in the linear groove 700, and the upper part of the head end of the wire 100 is exposed above the positioning shaft 101.

[0063] When the ring 102 is sleeved on the positioning shaft 101 , the inner ring sidewall abuts against the upper part of the head end of the wire 100 from top to bottom, and the welder 200 welds the upper part of the head end of the wire 100 to the end of the ring 102 for fixed connection.

[0064] By setting the linear groove 700, the linear guiding positioning of the head end of the wire 100 can be maintained, and the upper part of the head end of the wire 100 is exposed above the positioning shaft 101. When the ring 102 is sleeved on the positioning shaft 101, the abutment between the ring 102 and the head end of the wire 100 can be achieved.

[0065] In this embodiment, a pressure head 900 is provided above the positioning shaft 101, and two inclined pressure walls 902 are formed at the bottom of the pressure head 900; when the circular ring 102 is sleeved on the positioning shaft 101, the pressure head 900 moves downward until the two pressure walls 902 press on both sides of the circular ring 102, so that the circular ring 102 and the head end of the wire 100 are relatively fixed, and then the welder 200 is used to weld the head end of the wire 100 to the circular ring 102 for fixed connection.

[0066] When the ring 102 is sleeved on the positioning shaft 101, before welding, in order to ensure that the ring 102 and the positioning shaft 101 are relatively fixed, the ring 102 is pressed using the pressing head 900, and by setting two pressing walls 902, symmetrical pressing of the ring 102 can be achieved, avoiding force deviation of the ring 102 and avoiding deformation of the ring 102 during the pressing process.

[0067] In this embodiment, the lower part of the positioning shaft 101 is provided with a moving seat 800, and the lower part of the circular ring 102 is fixed in the moving seat 800. When the circular ring 102 is sleeved on the positioning shaft 101, the moving seat 800 moves downward, so that the circular ring 102 is fixed relative to the head end of the wire 100, and the movement of the circular ring 102 is limited.

[0068] When the head end of the wire 100 is welded and fixedly connected with the circular ring 102, the head end of the wire 100 is formed with a welding scar. The moving seat 800 lifts the circular ring 102 upward, and drives the head end of the wire 100 to deviate from the straight slot 700 upward until the welding scar is separated from the positioning shaft 101. After the wire pulling structure pulls the wire 100 to move a set distance, the moving clamp clamps the head end of the wire 100 to move.

[0069] During the process of welding and fixedly connecting the head end of the wire 100 with the circular ring 102, the welding scar may be adhered to the positioning shaft 101. At this time, the moving seat 800 lifts the circular ring 102, so that the welding scar is separated from the positioning shaft 101. After avoiding the adhesion phenomenon, the moving clamp can clamp the head end of the wire 100 to move after the wire pulling structure pulls a set distance.

[0070] In this embodiment, the middle part of the pressing head 900 has a bare empty area 901 for the laser of the welder 200 to pass through. The bare empty area 901 is arranged in alignment with the head end of the wire 100 placed on the positioning shaft 101. In this way, when the pressing head 900 presses the circular ring 102, so that the circular ring 102 is fixed relative to the head end of the wire 100, the laser emitted by the welder 200 can pass through the bare empty area 901 to weld the head end of the wire 100 and the circular ring 102.

[0071] In this embodiment, the bottom part of the straight slot 700 is provided with a wave-shaped elastic sheet. The bottom part of the elastic sheet is formed with a plurality of bottom parts 702 arranged at intervals. The bottom parts 702 are fixed in the straight slot 700. The top part of the elastic sheet is formed with a plurality of top parts arranged at intervals. The top part and the bottom part of the straight slot 700 have an elastic interval 703 therebetween.

[0072] The top part is concave downward to form a concave groove 701. Along the axial direction of the straight slot 700, the plurality of bottom parts 702 and the plurality of top parts are sequentially arranged at intervals.

[0073] By arranging the recessed grooves 701, the head end of the wire 100 can be placed in the straight groove 700 and abut in the plurality of recessed grooves 701. When the ring 102 is sleeved on the positioning shaft 101, the elastic deformation of the elastic sheet can be facilitated. When the ring 102 is sleeved on the positioning shaft 101, the abutting head 900 abuts against the ring 102, and the elastic sheet elastically deforms. When the ring 102 is welded and fixedly connected with the wire 100, the elastic sheet synchronously cooperates with the moving seat 800 to upwardly lift the wire 100 and the ring 102, so that the welding position is separated from the positioning shaft 101.

[0074] In the embodiment, the pull wire structure includes two pull wire clamps, which are arranged at intervals along the pulling direction of the wire 100. When the wire 100 needs to be pulled, the rear pull wire clamp clamps the wire 100, and the front pull wire clamp moves backward by a set distance to clamp the wire 100. The rear pull wire clamp releases the wire 100. At this time, the front pull wire clamp can pull the wire 100 to move forward by a set distance. Repeating the operation of the two pull wire clamps can realize intermittent pulling of the wire 100.

[0075] In the embodiment, during the movement of the wire 100 pulled by the pull wire structure, the wire 100 passes through the cleaning structure, the cleaning structure wipes and cleans the surface of the wire 100, and the wire 100 passes outside the air blowing port. The air blowing port blows ion wind to the cleaned wire 100 to remove static electricity of the wire 100.

[0076] The cleaning structure includes two cleaning plates arranged opposite to each other, and the cleaning plates are provided with cleaning pads. The wire 100 is arranged between the two cleaning plates. During the pulling of the wire 100, the wire 100 abuts against and wipes the cleaning pads, so that the wire 100 is wiped and cleaned.

[0077] In the embodiment, the ring vacuum suction head can be used to suck and feed the ring 102. After the ring vacuum suction head sucks the circumferential side of the ring 102, the ring 102 is arranged in a suspended state. The camera identifies the longitudinal angle of the ring 102, and drives the ring 102 to rotate longitudinally by rotating the ring vacuum suction head until the longitudinal angle of the ring 102 meets the set angle requirement.

[0078] When the ring vacuum suction head sucks the ring 102, the longitudinal angle of the ring 102 often deviates. In order to more accurately sleeve the ring 102 on the positioning shaft 101 subsequently, the longitudinal angle of the ring 102 needs to be adjusted.

[0079] In the embodiment, after the circular ring vacuum suction head drives the circular ring 102 to rotate longitudinally to adjust the longitudinal angle, the circular ring vacuum suction head places the circular ring 102 on the moving seat 800; the moving seat 800 is provided with a positioning groove, the bottom of the positioning groove is provided with a vacuum suction port, the circular ring vacuum suction head places the circular ring 102 in the positioning groove, after the vacuum suction port sucks the circular ring 102, the circular ring vacuum suction head is separated from the circular ring 102, and the moving seat 800 moves towards the positioning shaft 101, and after the circular ring 102 in the positioning groove is sleeved on the positioning shaft 101.

[0080] After the circular ring vacuum suction head adjusts the longitudinal angle of the circular ring 102 sucked, the circular ring 102 is placed in the positioning groove of the moving seat 800, so that the position of the circular ring 102 is accurate, and the phenomenon of angle deviation in the subsequent process is avoided.

[0081] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
