Technical Field

[0001] The utility model relates to the technical field of cooling air ducts, in particular to an improved cooling air duct device. Background Art

[0002] In the manufacturing industry, especially in the electronic manufacturing process, ribbon welding machines are widely used to weld metal parts. During operation, due to high current and rapid friction, ribbon welding machines will generate a lot of heat. If the heat cannot be dissipated in time, it will cause the equipment to overheat, performance degradation or even damage. Therefore, during welding work, cooling is usually carried out through a cooling system. Usually, the cooling system consists of a fan, cooling air duct, exhaust vent, etc.

[0003] However, the cooling air duct of the existing cooling system has a poor cooling effect on the welding strip, which easily increases the generation of tin spots during the welding process, resulting in a large number of defective products, thereby reducing the production quality. Therefore, the utility model provides an improved cooling air duct device to meet the needs. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose an improved cooling air duct device.

[0005] The technical problem to be solved by the utility model is to provide an improved cooling air duct device to solve the problem that the existing cooling air duct has a poor cooling effect on the welding strip, which easily increases the generation of tin spots during the welding process, causing a large number of defective products, thereby reducing the quality of the products.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An improved cooling air duct device, comprising:

[0008] At least two groups of air ducts are arranged relatively at the bottom of the welding strip, so that the inside of the air duct is a hollow structure, and the side of the air duct is penetrated by a plurality of air outlets facing the welding strip;

[0009] A fixed plate is arranged inside the air duct and divides the inside of the air duct into a first channel and a second channel, a through hole is penetrated on the fixed plate relative to the air outlet, and an air inlet communicating with the first channel is penetrated at the end of the air duct;

[0010] A partition plate is arranged along the through opening and is fixedly connected to the fixing plate and the air duct.

[0011] Preferably, a first guide plate is fixedly connected to one end of the fixing plate facing the air inlet, the first guide plate blocks the second channel, and the first guide plate has an inclined surface inclined toward the first channel.

[0012] Preferably, the inclined surface angle of the first guide plate is between 15° and 45°.

[0013] Preferably, the through opening is a terrace-shaped structure with a cross-sectional area decreasing from the first channel to the second channel.

[0015] Preferably, a second guide plate is fixedly connected to the air duct between the air outlet and the through opening, the second guide plate has an inclined surface inclined toward the welding strip, and the inclined surface of the second guide plate is arranged toward the through opening.

[0016] In the above scheme, by setting the air outlet and the first channel, the wind flow is discharged to the opening along the first channel, and is discharged to the air outlet under the guidance of the baffle.

[0027] like Figures 1 to 6 As shown, an embodiment of the utility model provides an improved cooling air duct device, including at least two groups of air ducts 1, which are relatively arranged at the bottom of the welding strip 11, so that the interior of the air duct 1 is a hollow structure, and a plurality of air outlets 2 facing the welding strip 11 are penetrated on the side of the air duct 1, and a fixed plate 5 is arranged inside the air duct 1 and divides the interior of the air duct 1 into a first channel 9 and a second channel 10, a through-hole 6 is penetrated on the fixed plate 5 relative to the air outlet 2, and an air inlet 3 connected to the first channel 9 is penetrated at the end of the air duct 1, and a partition 7 is arranged relatively along the through-hole 6 and fixedly connected to the fixed plate 5 and the air duct 1.

[0028] Specifically, the wind flow enters the air duct 1 through the air inlet 3 through an external device. Since the baffle blocks the second channel 10, the wind flow will be discharged to the first channel 9, and discharged to the opening 6 through the first channel 9, and then discharged to the air outlet 2 along the opening 6 to cool the welding strip 11 on the top of the air duct 1. Among them, the setting of the first channel 9 divides the overall area inside the air duct 1, so that the flow rate of the wind flow discharged to the first channel 9 is increased, thereby increasing the wind flow at the air outlet 2, and then accelerating the cooling effect on the welding strip 11. At the same time, by increasing the number of air outlets 2 and reducing the cooling distance between the air outlet 2 and the welding strip 11, the wind is concentrated to cool the welding strip 11, which can effectively reduce tin spots and defective products, improve product quality, and solve the problem that the existing cooling air duct has a poor cooling effect on the welding strip 11, which is easy to increase the generation of tin spots during welding, resulting in a large number of defective products, thereby reducing the problem of quality.

[0029] It should be noted that the welding strip 11 is set on the top of the air duct 1 through a bracket. During the welding process, the wind pressure of the air outlet 2 will be discharged upward to the welding strip 11 for cooling. By reducing the cooling distance between the air outlet 2 and the welding strip 11, the cooling effect on the welding strip 11 is improved, thereby ensuring the quality of the product.

[0030] like Figure 3 and Figure 4As shown, in the present embodiment, a first guide plate 4 is fixedly connected to one end of the fixing plate 5 facing the air inlet 3, the first guide plate 4 blocks the second channel 10, and the first guide plate 4 has an inclined surface inclined toward the first channel 9, and the angle of the inclined surface of the first guide plate 4 is between 15° and 45°. Specifically, the first guide plate 4 can guide the wind flow into the first channel 9, thereby increasing the wind pressure of the first channel 9, thereby increasing the wind pressure at the air outlet 2, and improving the cooling efficiency of the welding strip 11.

[0031] like Figure 3 , Figure 5 and Figure 6 As shown, in the present embodiment, the through opening 6 is a trapezoidal structure with a decreasing cross-sectional area from the first channel 9 to the second channel 10, and the orthographic projection area of ​​the air outlet 2 is smaller than the orthographic projection area of ​​the through opening 6. Specifically, the through opening 6 adopts a trapezoidal structure design to increase the wind pressure discharged toward the air outlet 2 along the first channel 9, thereby increasing the wind pressure discharged toward the welding strip 11 from the air outlet 2, and improving the cooling efficiency of the welding strip 11.

[0032] like Figure 4 and Figure 5 As shown, in the present embodiment, a second guide plate 8 is fixedly connected to the air duct 1 between the air outlet 2 and the through opening 6, and the second guide plate 8 has an inclined surface inclined toward the welding strip 11, and the inclined surface of the second guide plate 8 is arranged toward the through opening 6. Specifically, the second guide plate 8 can guide the airflow discharged from the through opening 6 to the direction of the welding strip 11, thereby avoiding convection of the airflow discharged from the air outlet 2 arranged relatively on the air duct 1, thereby improving the cooling effect of the ground welding strip 11.

[0033] Working principle:

[0034] The wind flow is led into the air duct 1 through the air inlet 3 by an external device. Since the baffle and the first guide plate 4 block the second channel 10, the wind flow is discharged to the first channel 9, and discharged to the opening 6 through the first channel 9, and then discharged to the air outlet 2 along the opening 6 and the welding strip 11 on the top of the air duct 1 is cooled by the guidance of the second guide plate 8. By increasing the number of air outlets 2 and reducing the cooling distance between the air outlet 2 and the welding strip 11, the wind power is concentrated to cool the welding strip 11, which can effectively reduce tin spots and defective products, improve product quality, and solve the problem that the existing cooling air duct has a poor cooling effect on the welding strip 11, which is easy to increase the generation of tin spots during the welding process, resulting in a large number of defective products, thereby reducing the problem of quality.
