Description

Technical Field

[0001] This utility model relates to the field of loudspeaker spot welding technology, and in particular to a spot welding device for loudspeaker production. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, producing sound. In loudspeaker manufacturing, spot welding is a crucial process for connecting various components, primarily used for welding voice coils, leads, and other critical parts. Traditional spot welding equipment typically uses a single welding head design, requiring multiple adjustments to the workpiece position to complete the welding of multiple points. This not only increases operation time but also easily affects welding quality due to inaccurate positioning.

[0003] Therefore, the shortcomings in the loudspeaker manufacturing process are mainly reflected in the following aspects:

[0004] First, it is difficult to position the loudspeaker during spot welding, especially for workpieces that require multiple welding points. Operators need to repeatedly adjust the position, which is inefficient and makes it difficult to guarantee accuracy.

[0005] Secondly, a single spot welding machine can only weld one spot at a time. For workpieces that require symmetrical or densely packed spots, multiple operations are required, which increases production time and costs. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a spot welding equipment for loudspeaker production, which overcomes the shortcomings of the prior art and effectively solves the problems of difficult positioning and slow spot welding efficiency of loudspeakers during spot welding.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A spot welding device for loudspeaker production includes a machine base, a slide rail is fixedly connected to the top outer wall of the machine base by screws, and a slide table for placing loudspeakers is slidably connected to the outer wall of the slide rail. Adjacent limit knobs are screwed to the top outer wall of the slide rail.

[0009] The top outer wall of the machine base is fixedly connected to a boom by screws, and the top outer wall of the boom is fixedly connected to a cylinder by screws. The piston rod of the cylinder is fixedly connected to a mounting bracket, and a fixed spot welding machine is fixedly connected to the inner wall of the mounting bracket. A connecting seat is slidably connected to the top outer wall of the mounting bracket, and a movable spot welding machine is fixedly connected to the inner wall of the connecting seat. A traction sleeve is installed on the outer wall of the movable spot welding machine, and a lead screw is screwed to one side of the outer wall of the traction sleeve.

[0010] Preferably, both ends of the outer wall of the lead screw are rotatably connected to one side of the outer wall of the mounting frame via bearing seats.

[0011] Preferably, a support ring is welded to the inner wall of the top of the mounting frame, and a dust suction hood is fixedly connected to the inner wall of the support ring. A dust suction pipe for absorbing smoke and dust is installed on the outer wall of one end of the dust suction hood.

[0012] Preferably, the dust suction hood has a dust suction port at the end away from the dust suction pipe, and both the fixed spot welding machine and the movable spot welding machine are located inside the dust suction port.

[0013] Preferably, the top outer wall of the slide rail has equidistantly distributed positioning holes, and the limiting knob is screwed onto the inner wall of the positioning holes. Both sides of the slide table have arc-shaped limiting grooves, and the size of the arc-shaped limiting grooves is adapted to the size of the limiting knob.

[0014] Preferably, a switch is provided on the outer wall of the top of the machine tool, and the switch is connected to the cylinder via a signal line.

[0015] The beneficial effects of this utility model are as follows:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 Example 1: A spot welding device for loudspeaker production includes a machine base 1. A slide rail 2 is fixedly connected to the top outer wall of the machine base 1 by screws, and a slide table 3 for placing loudspeakers is slidably connected to the outer wall of the slide rail 2. Adjacent limit knobs 4 are screwed to the top outer wall of the slide rail 2.

[0026] The top outer wall of the slide rail 2 is provided with equidistant positioning holes 16, and the limiting knob 4 is screwed onto the inner wall of the positioning holes 16. The outer walls on both sides of the slide table 3 are provided with arc-shaped limiting grooves 17, and the size of the arc-shaped limiting grooves 17 is adapted to the size of the limiting knob 4.

[0027] A slide rail 2 is mounted on the top of the machine base 1, and a slide table 3 is slidably connected to the slide rail 2 for placing speaker workpieces. The top of the slide rail 2 has equidistantly distributed positioning holes 16, and a limit knob 4 is fixed in the positioning holes 16 by a threaded connection. Arc-shaped limit grooves 17 are formed on both sides of the slide table 3, their dimensions matching those of the limit knob 4, ensuring precise positioning of the slide table 3 after it slides into place.

[0028] In this embodiment, the speaker is positioned quickly and accurately by means of the cooperation of the slide rail 2, the slide table 3 and the limiting knob 4. The slide table 3 can slide along the slide rail 2 and is fixed in the positioning hole 16 by the limiting knob 4. Combined with the design of the arc-shaped limiting groove 17, the position of the workpiece is effectively avoided from shifting during the welding process, thereby improving the welding accuracy and efficiency.

A mounting bracket 7 is fixedly connected to the piston rod of the cylinder 6, and a fixed spot welding machine 8 is fixedly connected to the inner wall of the mounting bracket 7. A connecting seat 9 is slidably connected to the top outer wall of the mounting bracket 7, and a movable spot welding machine 10 is fixedly connected to the inner wall of the connecting seat 9. A traction sleeve 11 is installed on the outer wall of the movable spot welding machine 10, and a lead screw 12 is screwed to one side of the outer wall of the traction sleeve 11. Both ends of the outer wall of the lead screw 12 are rotatably connected to one side of the outer wall of the mounting bracket 7 through bearing seats.

[0030] The boom 5 is fixed to the top of the machine base 1. The cylinder 6 is mounted on the boom 5 with screws, and the piston rod of the cylinder 6 is connected to the mounting frame 7. A fixed spot welding machine 8 is fixed inside the mounting frame 7. A connecting seat 9 is slidably connected to the top of the mounting frame 7. A movable spot welding machine 10 is fixed on the connecting seat 9. The traction sleeve 11 is connected to the movable spot welding machine 10 and its position is adjusted by the lead screw 12. The two ends of the lead screw 12 are fixed to the mounting frame 7 by bearing seats to ensure smooth adjustment.

[0031] In this embodiment, a dual-welding head design is adopted. The position of the movable spot welding machine 10 is adjusted by the lead screw 12, which can complete the welding of two weld points at one time. The distance between the weld points can be flexibly adjusted according to actual needs, which not only reduces the number of operations but also improves production efficiency.

[0034] A switch 18 is installed on the top outer wall of the machine tool 1, and the switch 18 is connected to the cylinder 6 via a signal line.

[0035] The switch 18 on the machine tool 1 controls the lifting and lowering of the cylinder 6 via a signal line to achieve automated operation.

[0036] Working principle:

[0037] Positioning stage: Place the speaker workpiece on the slide table 3, manually slide it along the slide rail 2 to the desired position, tighten the limit knob 4 to make it lock into the arc-shaped limit groove 17, keep it still, and complete the precise positioning of the workpiece.

[0038] Welding stage: The cylinder 6 is activated by switch 18, which drives the mounting bracket 7 to descend, so that the fixed spot welding machine 8 and the movable spot welding machine 10 come into contact with the workpiece. The position of the movable spot welding machine 10 can be adjusted by rotating the screw 12 to meet different welding point spacing requirements. The two welding heads work at the same time to complete two welding points at one time.

[0039] Fume and dust treatment: The fumes and dust generated during the welding process are captured by the dust hood 14 and discharged through the dust suction pipe 15 to keep the working environment clean. After welding is completed, the cylinder 6 drives the mounting bracket 7 to rise and remove the workpiece.
