Description

Technical Field

[0001] This utility model relates to the field of earring processing technology, specifically to an automatic earring welding equipment. Background Technology

[0002] In earring manufacturing, the needles are typically fed continuously first. Then, a robotic arm moves the needles and decorative beads to the clamping station and applies flux. After welding, the needles are inspected and unloaded. Throughout this process, a continuous rotary table moves the material between multiple processing stations, thus achieving fully automated welding.

[0003] Existing automatic earring welding equipment mainly uses a vibratory feeder. However, the needles required for earring processing are lightweight and slender, which makes it difficult to discharge the needles during vibratory feeding. Furthermore, the needles tend to accumulate and get stuck when they enter the discharge trough. To solve these problems, an automatic earring welding equipment is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic earring welding device, which solves the problem that existing automatic earring welding devices use a vibratory feeder, which, due to the light weight and slender shape of the needles, makes it difficult for the needles to enter the discharge trough and easily leads to material accumulation and jamming.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic earring welding device, including a welding table and a welding unit installed on the welding table. A needle feeding unit is provided on one side of the welding unit. The needle feeding unit includes a material box and a linear vibrating feeder provided on one side of the material box. A linear feeder is vertically slidably arranged inside the material box. The linear feeder pushes the needles in the material box vertically into the linear vibrating feeder. A needle feeding groove is opened in the middle of the linear vibrating feeder. The ends of the needle groove are recessed towards the center on both sides, so that the needle tip slides down towards the center and enters the needle groove. The front end of the needle slot is tilted downwards on the side near the material box so that needles that have not entered the needle slot fall back into the material box.

[0006] Preferably, the welding unit includes an electric turntable fixedly mounted on the welding table, and the electric turntable has multiple clamping stations arranged in a circular array.

[0007] Preferably, the welding table is arranged in a circular array outside the electric turntable, including a welding needle distributor, a spot welding station, a flux application station, a flux addition station, a residue detection station, and a product inspection station.

[0008] Preferably, a control switch, a ball feeder, and a solenoid valve assembly are fixedly installed on the welding table, and the needle discharge unit, control switch, ball feeder, and solenoid valve assembly are respectively located at the four top corners of the welding table.

[0009] Preferably, a support base is fixedly provided on the welding table, and the material box and the linear vibrating feed rail are both installed on the support base.

[0010] Preferably, a drive cylinder is fixedly installed at the top of one end of the support base, a material distribution plate is rotatably installed on the support base, a gear is fixedly installed at one end of the material distribution plate, a rack is slidably installed on the support base, the output end of the drive cylinder is fixedly connected to the rack, and the rack meshes with the gear.

[0011] Preferably, the dispensing disc has a needle slot adapted to the needle slot, so that when the dispensing disc is rotated to be flush with the top of the linear vibrating feed rail, the needle in the needle slot can move into the needle slot.

[0012] Preferably, the linear feeder includes a lifting cylinder fixedly disposed on one side of the material box. The output end of the lifting cylinder is fixedly disposed with a first-stage top plate and a second-stage top plate, which push the needle upward to the top of the linear vibrating feed rail.

[0013] Preferably, the inner bottom of the material box is provided with a first material collection groove, the first-stage top plate is slidably disposed in the first material collection groove, the outer wall of the material box and the linear vibrating feeding rail are provided with a feeding gap, and the second-stage top plate is slidably disposed in the feeding gap.

[0014] This utility model discloses an automatic earring welding device, which has the following beneficial effects: By activating the lifting cylinder, it synchronously drives the first-stage top plate and the second-stage top plate to move upward. The first-stage top plate pushes some of the needles upward, so that the needles move to the feeding gap position. Then, the second-stage top plate pushes the needles to the top of the linear vibrating feed rail. Since the top two sides of the end of the linear vibrating feed rail are inclined towards the middle, the needles can slide down towards the middle. Some needles can smoothly enter the needle slot, while some needles that do not enter the needle slot continue to move forward with the vibration of the linear vibrating feed rail. When they move to the front end of the linear vibrating feed rail, they slide down from the inner inclined side of the linear vibrating feed rail and return to the inside of the material box, thereby effectively solving the problem of needles being difficult to enter the needle slot and the accumulation and jamming of materials.

[0019] This application provides an automatic earring welding device, which solves the problem that existing automatic earring welding devices use a vibratory feeder, which has problems such as the needles being difficult to enter the discharge trough and easy accumulation and jamming due to the light weight and slender shape of the needles.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model discloses an automatic earring welding device.

[0022] According to the appendix Figure 1-4 As shown, it includes a welding table 1 and a welding unit 3 installed on the welding table 1. A needle discharge unit 2 is provided on one side of the welding unit 3. The needle discharge unit 2 includes a material box 22 and a linear vibrating feed rail 23 provided on one side of the material box 22. A linear feeder is vertically slidably arranged inside the material box 22. The needles in the material box 22 are vertically pushed into the linear vibrating feed rail 23 by the linear feeder. A needle discharge groove 213 is opened in the middle of the linear vibrating feed rail 23. The ends of the needle groove 213 are recessed towards the center on both sides, so that the needle tip slides towards the center and enters the needle groove 213. The front end of the needle slot 213 is tilted downward on the side near the material box 22 so that needles that do not enter the needle slot 213 fall back into the material box 22.

[0023] The welding unit 3 includes an electric turntable 31 fixedly mounted on the welding table 1, and multiple clamping stations 310 are arranged in a ring array on the electric turntable 31.

[0024] On the welding table 1, located outside the electric turntable 31, there are a welding needle distributor 32, a spot welding station 33, a flux application station 34, a flux addition station 35, a residue inspection station 36, and a product inspection station 37 arranged in a ring array.

[0025] The welding table 1 is fixedly equipped with a control switch 4, a ball feeder 39 and a solenoid valve group 38, and the needle discharge unit 2, the control switch 4, the ball feeder 39 and the solenoid valve group 38 are respectively located at the four corners of the top of the welding table 1.

[0026] A support base 21 is fixedly installed on the welding table 1, and the material box 22 and the linear vibrating feed rail 23 are both installed on the support base 21.

[0027] A drive cylinder 24 is fixedly installed at the top of one end of the support base 21. A material distribution plate 27 is rotatably installed on the support base 21. A gear 26 is fixedly installed at one end of the material distribution plate 27. A rack 25 is slidably installed on the support base 21. The output end of the drive cylinder 24 is fixedly connected to the rack 25. The rack 25 meshes with the gear 26.

[0028] The dispensing tray 27 has a needle slot adapted to the needle slot 213, so that when the dispensing tray 27 rotates to be flush with the top of the linear vibrating feed rail 23, the needle in the needle slot 213 can move into the needle slot.

[0029] The linear feeder includes a lifting cylinder 28 fixedly installed on one side of the material box 22. The output end of the lifting cylinder 28 is fixedly provided with a first-stage top plate 29 and a second-stage top plate 210. The needle is pushed upward to the top of the linear vibrating feed rail 23 through the first-stage top plate 29 and the second-stage top plate 210.

[0030] The bottom of the material box 22 is provided with a first material collection groove 211, and a first-stage top plate 29 is slidably disposed in the first material collection groove 211. The outer wall of the material box 22 and the linear vibrating feeding rail 23 are provided with a feeding gap 212, and a second-stage top plate 210 is slidably disposed in the feeding gap 212.

[0031] Working principle: When in use, the needle is placed inside the material box 22. Under gravity, the needle slides down inside the box, with some entering the first collection trough 211. At this point, the lifting cylinder 28 is activated, simultaneously moving the first-stage top plate 29 and the second-stage top plate 210 upwards. The first-stage top plate 29 pushes some of the needles upwards, moving them to the feeding gap 212. Some of the needles then slide down into the feeding gap 212 and are positioned on top of the second-stage top plate 210. The second-stage top plate 210 then continues to move. When the needle tip is placed on top of the linear vibrating feed rail 23, the needle tip can slide down to the center due to the inclination of the two sides of the top end of the linear vibrating feed rail 23. At this time, some needle tips can smoothly enter the needle slot 213, while some needle tips that do not enter the needle slot 213 continue to move forward as the linear vibrating feed rail 23 vibrates. When they move to the front end of the linear vibrating feed rail 23, they slide down from the inner inclined side of the linear vibrating feed rail 23 and return to the inside of the material box 22, thus effectively solving the problem of needle tips being difficult to enter the needle slot and the accumulation and jamming of materials. Then, the distribution plate 27 is rotated by the drive cylinder 24, so that when the needle slot inside the distribution plate 27 is aligned with the needle slot 213, it can just accommodate a set of needles. Then the distribution plate 27 rotates to take out a set of needles, and then the robot moves them to the clamping station 310. The ball feeder 39 feeds the ball into the clamping station 310. Then the ball and needle enter the flux coating station 34 for flux coating. Then the flux addition station 35 adds flux if it is insufficient. Then the welding is carried out through the spot welding station 33. After the welding is completed, the product inspection station 37 is used for inspection and unloading, and the welding is completed.
