Description

Technical Field

[0001] This application relates to the field of grounding wire manufacturing technology, and in particular to an adsorption device for welding grounding wires. Background Technology

[0002] A ground wire is a conductor used to connect a car body to other metal components. It is typically used to connect the negative terminal of a car's electrical system to the metal body or chassis. A ground wire generally consists of a metal conductor and a lap metal tab with a round hole. The outer surface of the metal conductor is covered with an insulating sheath, and the lap metal tab is soldered to the metal conductor. In the current manufacturing process, workers need to use their fingers to clamp and secure the lap metal tab before placing it at the welding end of the metal conductor (i.e., the welding station) for welding. This manual method of clamping and transferring the metal tab is not only inefficient but also poses a safety hazard because it places the worker's fingers too close to the welding station; therefore, it needs improvement. Utility Model Content

[0003] This application provides an adsorption device for welding ground wires to improve the following technical problems:

[0004] Manually gripping and transferring metal sheets is not only inefficient, but also poses a safety hazard because it puts workers' fingers too close to the welding station.

[0005] This application provides an adsorption device for welding ground wires, which adopts the following technical solution:

[0006] An adsorption device for welding ground wires includes a base, a support, a rotating unit, an adsorption electromagnet, and a lifting drive unit. The support is mounted on the base, the rotating unit is vertically slidably mounted on the support, multiple adsorption electromagnets are spaced apart at the bottom of the rotating unit, and the lifting drive unit is located between the support and the rotating unit. The lifting drive unit is used to drive the rotating unit to rise or fall, the adsorption electromagnets are used to magnetically attract stacked overlapping metal sheets, and the rotating unit is used to drive the adsorption electromagnets to rotate horizontally to transport the overlapping metal sheets to the welding station.

[0007] In one feasible technical solution of this application, the rotating unit includes a lifting plate and a first servo motor. One side of the lifting plate is vertically slidably mounted on one side of the bracket. The lifting plate is horizontally arranged. The first servo motor is installed on the lower surface of the lifting plate. The output shaft of the first servo motor is arranged downward and vertically connected to a horizontally arranged turntable.

[0008] In one feasible technical solution of this application, the adsorption electromagnet has 3-6 groups, and the multiple groups of adsorption electromagnets are evenly and symmetrically arranged around the center of the turntable, and the adsorption electromagnets are vertically connected to the lower surface of the turntable.

[0009] In one feasible technical solution of this application, the peripheral sidewall of the turntable is provided with multiple sets of distance measuring sensors, and the distance measuring sensors are arranged in a one-to-one correspondence with the adsorption electromagnets. The distance measuring sensors are used to sense the vertical distance between the adsorption electromagnets and the overlapping metal sheets to be transferred.

[0010] In one feasible technical solution of this application, a vertical guide rod is provided on one side of the bracket, and a circular hole is provided on one side of the lifting plate, with the vertical guide rod sliding through the circular hole.

[0011] In one feasible technical solution of this application, the lifting drive unit and the vertical guide rod are respectively disposed on opposite sides of the bracket.

[0012] In one feasible technical solution of this application, the lifting drive unit includes a transmission screw and a second servo motor. The transmission screw is arranged vertically, and its bottom is rotatably mounted on the base. The second servo motor is mounted on the top of the bracket, and its output shaft is connected to the top of the transmission screw. The transmission screw is threadedly mounted on the side of the lifting plate.

[0013] In one feasible technical solution of this application, a thin rubber sleeve is provided on the outer surface of the adsorption electromagnet.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] The lifting drive unit is activated, which automatically drives the rotating unit to rise or fall. When the rotating unit descends to the point where the electromagnet is close to the topmost overlapping metal piece, the electromagnet is activated again to magnetically fix the topmost overlapping metal piece. Then, the rotating unit is activated to transport the overlapping metal piece to the welding station. This device can efficiently and automatically pick up and transfer overlapping metal pieces, improving production efficiency. It also effectively prevents workers' fingers from getting too close to the welding station, reducing safety hazards. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1This application will be described in further detail.

[0030] This application discloses an adsorption device for welding ground wires. (Refer to...) Figure 1 The adsorption device for welding ground wires includes a base 1, a bracket 2, a rotating unit 3, an adsorption electromagnet 4, and a lifting drive unit 5. The bracket 2 is mounted on the base 1, the rotating unit 3 is vertically slidably mounted on the bracket 2, multiple adsorption electromagnets 4 are spaced apart at the bottom of the rotating unit 3, and the lifting drive unit 5 is located between the bracket 2 and the rotating unit 3. The lifting drive unit 5 is used to drive the rotating unit 3 to rise or fall, the adsorption electromagnets 4 are used to magnetically attract stacked overlapping metal sheets, and the rotating unit 3 is used to drive the adsorption electromagnets 4 to rotate horizontally to transport the overlapping metal sheets to the welding station.

[0031] In this embodiment, the rotating unit 3 includes a lifting plate 31 and a first servo motor 32. One side of the lifting plate 31 is vertically slidably mounted on one side of the bracket 2. The lifting plate 31 is horizontally arranged. The first servo motor 32 is installed on the lower surface of the lifting plate 31. The output shaft of the first servo motor 32 is arranged downward and vertically connected to a horizontally arranged turntable 33.

[0032] The electromagnet 4 has 3-6 groups (preferably 4 groups), and the multiple groups of electromagnets 4 are evenly and symmetrically arranged around the center of the turntable 33, and the electromagnets 4 are vertically connected to the lower surface of the turntable 33.

[0033] The rotating unit 3 designed above has a simple and robust structure, stable operation, and is relatively easy to operate. It can stably drive the adsorption electromagnet 4 to rotate to the required angle according to the preset PLC control program.

[0034] In addition, in order to facilitate the magnetic attraction and fixation of the stacked metal sheets by the electromagnet 4 one by one, the sidewall of the turntable 33 is provided with multiple sets of distance sensors 6. The distance sensors 6 are arranged in a one-to-one correspondence with the electromagnet 4. The distance sensors 6 are used to sense the vertical distance between the electromagnet 4 and the stacked metal sheets to be transferred.

[0035] To ensure that the lifting plate 31 can rise and fall stably and is not prone to shaking, a vertical guide rod 21 is provided on one side of the bracket 2, and a round hole is provided on one side of the lifting plate 31, through which the vertical guide rod 21 slides.

[0036] In addition to ensuring the structural stability of the bracket 2, and to effectively prevent the lifting drive unit 5 from being interfered with by other components during operation, the lifting drive unit 5 and the vertical guide rod 21 are respectively located on opposite sides of the bracket 2.

[0037] In this embodiment, the lifting drive unit 5 includes a transmission screw 51 and a second servo motor 52. The transmission screw 51 is arranged vertically, and its bottom is rotatably mounted on the base 1. The second servo motor 52 is mounted on the top of the bracket 2, and its output shaft is connected to the top of the transmission screw 51. The transmission screw 51 is threaded through and mounted on the side of the lifting plate 31.

[0038] To effectively prevent damage from collision between the electromagnet 4 and the overlapping metal sheet, a thin rubber sleeve 41 is provided on the outer surface of the electromagnet 4.

[0039] The beneficial technical effects of the adsorption device for welding ground wires in this application are roughly as follows:

[0040] The lifting drive unit 5 is activated, which automatically drives the rotating unit 3 to rise or fall. When the rotating unit 3 descends to the point where the electromagnet 4 is close to the topmost overlapping metal piece, the electromagnet 4 is activated again to magnetically fix the topmost overlapping metal piece. Then, the rotating unit 3 is activated to transport the overlapping metal piece to the welding station. This device can efficiently and automatically pick up and transfer overlapping metal pieces, improving production efficiency. It also effectively prevents workers' fingers from getting too close to the welding station, reducing safety hazards.
