Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve manufacturing technology, and in particular to a continuous welding mechanism for electromagnetic valves. Background Technology

[0002] Solenoid valves, as key components that control the valve core's movement via an electromagnetic coil to achieve fluid flow control, are widely used in automation control, hydraulics, pneumatics, and home appliance manufacturing. The stability and reliability of their performance largely depend on the welding quality between the coil leads and the valve seat (or other conductive components). Insufficient welding strength can lead to poor contact, while welding position deviations can cause uneven coil stress and reduced insulation performance. Therefore, the welding process for the coil leads is one of the core steps in the solenoid valve manufacturing process.

[0003] In a typical assembly process for a solenoid valve, the coil usually needs to be welded to the valve seat via leads at both ends: First, one lead of the coil is welded to a pre-set welding point on the valve seat (i.e., initial welding); then, since the other lead of the coil and the welding point on the valve seat are on the other side of the solenoid valve, the solenoid valve needs to be rotated (usually 180°) so that the other lead is aligned with the electrode or positioning structure of the welding assembly; finally, the rotated solenoid valve is precisely placed on the welding assembly to complete the welding of the other lead of the coil (i.e., final welding).

[0004] Currently, the aforementioned actions of "solenoid valve reversal" and "feeding the valve to the welding assembly after reversal" are mainly performed manually. The specific operation process is as follows: the operator picks up the solenoid valve that has completed the initial welding at the first welding station, rotates the solenoid valve 180° by hand, and then manually adjusts the solenoid valve's posture to align it with the positioning groove, electrodes, and other structures of the welding assembly. Finally, the solenoid valve is placed in the preset position of the welding assembly, awaiting continuous welding at the end. This welding structure is labor-intensive, has poor positioning accuracy, and low production efficiency. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown, the continuous welding mechanism for an electromagnetic valve according to this utility model includes a welding assembly 2, a discharge conveying robot 4, and a circulating conveyor line 8; the discharge conveying robot 4 is used to remove the product from the welding assembly 2. A welding machine feeding assembly 1 is provided between the circulating conveyor line 8 and the welding assembly 2; the welding machine feeding assembly 1 is used to take out one of the products on the circulating conveyor line 8, flip it over, and put it into the welding assembly 2; Both the welding machine feeding assembly 1 and the discharge conveying robot 4 are equipped with feeding and discharging clamping assemblies 6; The welding assembly 2, the discharge conveying robot 4, and the circulating conveyor line 8 are not fundamentally different from existing technologies, so they will not be described in detail; the infeed and discharge gripping assembly 6 is used to grip the product; The welding assembly 2 includes a turntable; each station of the turntable is equipped with a fixture for clamping products; the corresponding stations are a shaping station for shaping the lead wire, a fluxing station for applying flux, and two welding stations, which weld different materials sequentially on the lead wire; the shaping station, fluxing station, and welding station are essentially the same as those in the prior art, so they will not be described in detail. The circulating conveyor line 8 is equipped with a fixture for clamping products; the welding machine feeding assembly 1 picks up a product from the fixture in the circulating conveyor line 8 and rotates it 180 degrees so that the welding position is facing upward. Then the welding machine feeding assembly 1 puts the product into the welding assembly 2 and performs continuous welding through the welding assembly 2. After welding is completed, the product is taken out from the welding assembly 2 by the discharge conveying robot 4. This structure enables automatic loading and unloading of welding materials, as well as the flipping of the loading process, reducing labor intensity, improving positioning accuracy, and increasing production efficiency.

[0018] As a preferred embodiment of the present invention, it further includes a first defective discharge track 5 and a second defective discharge track 3; a waste material gripping robot 7 is provided between the circulating conveyor line 8 and the first defective discharge track 5.

The three work together to grab and transport the product. The waste grabbing robot 7 is not fundamentally different from existing technology, so it will not be described in detail. The circulating conveyor line 8 is equipped with a vision inspection device. The vision inspection device checks whether the appearance of the welding position of the first lead wire and the valve seat is qualified. Only qualified products enter the area below the welding machine feeding assembly 1. Before welding, unqualified products are taken out by the waste grabbing robot 7 and placed into the first defective discharge track 5 for collection. The first defective discharge track 5 is an inclined long guide rail structure. After the defective products are grabbed by the waste grabbing robot 7, they are placed into the inclined first defective discharge track 5. Then, under the action of gravity, the products slide down into the waste collection box at the end of the first defective discharge track 5.

[0019] In a preferred embodiment of this utility model, the welding machine feeding assembly 1, the discharge conveying robot 4, and the waste grabbing robot 7 are all equipped with feeding and discharging clamping assemblies 6; the feeding and discharging clamping assembly 6 includes a feeding and discharging clamping claw cylinder 602; a clamping plate 601 is fixed on each of the two clamping toes of the feeding and discharging clamping claw cylinder 602; an arc-shaped clamping block 60101 is provided on the inner side wall of the clamping plate 601; a clamping chamfered surface 60102 is provided between the inner side surface of the arc-shaped clamping block 60101 and the top surface of the arc-shaped clamping block 60101; The inner groove radius of the arc-shaped clamping block 60101 matches the concave ring on the outer side wall of the product.

Then, the product rotating component rotates the product 180 degrees, and the product transfer component then transports the 180-degree rotated product from the rotating component to the welding assembly 2.

[0021] In a preferred embodiment of this utility model, the product transfer component includes a feeding fixing frame 101, a feeding translation frame 102 slidably connected to the feeding fixing frame 101, and a feeding lifting slide plate 105 slidably connected to the feeding translation frame 102; a feeding translation linear module 104 is connected between the feeding fixing frame 101 and the feeding translation frame 102; a feeding lifting linear module 103 is connected between the feeding translation frame 102 and the feeding lifting slide plate 105; and an infeed / outfeed clamping assembly 6 is fixed on the feeding lifting slide plate 105.

[0022] In a preferred embodiment of this utility model, the number of infeed / outfeed clamping components 6 on the feeding lifting slide plate 105 is two. Positioned sequentially at the welding component 2, the product rotating component, and the circulating conveyor line 8; when the product is simultaneously picked up from the circulating conveyor line 8 and from the product rotating component, the distance between the welding component 2 and the product rotating component is equal to the distance between the two infeed / outfeed clamping components 6 on the feeding lifting slide plate 105. When the product rotating part and welding assembly 2 are fed out synchronously, the distance between the welding assembly 2 and the product rotating part is equal to the distance between the two feeding and discharging clamping assemblies 6 on the feeding lifting slide plate 105. Two feeding and discharging clamping assemblies 6 are moved synchronously.

By adjusting the position of the feeding and discharging clamping component 6 on the feeding rotary module 108, the welding component 2 and the circulating conveyor line 8 can still achieve synchronous feeding and discharging even when the clamping distance is not equal to twice the clamping distance, after the adjustment of the linear module 106, making the layout of the welding mechanism more flexible.
