Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and more specifically, to a cooling device for laser welding. Background Technology

[0002] In laser welding, a large amount of heat is generated. If the welded product is not cooled, the welding quality may be affected. Therefore, equipping the laser welding process with an efficient cooling device is crucial.

[0003] Currently, most existing laser welding cooling devices employ a simple circulating cooling method using a storage tank. During the cooling process, impurities and other contaminants generated during welding inevitably mix into the coolant. These contaminants gradually accumulate in the filter components, which are typically fixed in location, making disassembly and cleaning complex and inconvenient to use. Therefore, we propose an improvement to this design, creating a new cooling device for laser welding. Utility Model Content

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-4 A cooling device for laser welding includes a storage tank 1 and a filter tank 105 located on one side of the storage tank 1. An L-shaped plate 104 is installed on the side of the filter tank 105 near the storage tank 1 and is suspended on the side wall of the storage tank 1. A groove 108 is provided on the top of the storage tank 1, and a connecting pipe 107 is inserted into the inner wall of the groove 108. One end of the connecting pipe 107 is connected to the bottom of the filter tank 105 near the storage tank 1. A first filter cotton 106 is placed in the filter tank 105. By using the L-shaped plate 104 to suspend the filter tank 105 on the storage tank 1, the filter tank 105 can be easily removed from the storage tank 1. When it is necessary to clean or replace the first filter cotton 106, there is no need to perform complicated disassembly operations. Simply remove the filter tank 105 from the storage tank 1 for operation. The operation is convenient and easy to use.

[0027] Furthermore, the top of the liquid storage tank 1 is provided with several slots 109, and each slot 109 has a rod 110 inserted into its inner wall. The tops of the rods 110 are fixedly connected to a cooling pool 101. By inserting the rods 110 into the slots 109, the rods 110 and the liquid storage tank 1 can cooperate to support the cooling pool 101. Pulling the cooling pool 101 upwards separates the rods 110 from the slots 109, allowing the cooling pool 101 to be removed from the top of the liquid storage tank 1 for easy cleaning of the inside of the liquid storage tank 1. The installation is completed by inserting the rods 110 into the slots 109, making it convenient to install and remove, and easy to use.

[0028] Furthermore, a first drain valve 102 is provided on one side of the cooling pool 101. The first drain valve 102 is connected to a first hose 103, and the bottom end of the first hose 103 extends into the filter pool 105. The coolant in the cooling pool 101 is discharged into the filter pool 105 from the first drain valve 102 and the first hose 103. After being filtered by the first filter cotton 106, it flows back to the storage pool 1 through the connecting pipe 107.

[0029] Furthermore, a third fixing seat 406 is installed on the side of the cooling pool 101 away from the first drain valve 102. A second fixing seat 405 is bolted to the top of the third fixing seat 406. A third hose 403 and a universal bamboo tube 404 are respectively connected to the two sides of the second fixing seat 405, and the third hose 403 and the universal bamboo tube 404 are connected. The universal bamboo tube 404 is used to spray out coolant.

[0030] Furthermore, a first fixed base 401 is installed on the side of the liquid storage tank 1, and a circulation pump 4 is installed on the top of the first fixed base 401. The outlet end of the circulation pump 4 is connected to the bottom of the third hose 403. The length of the third hose 403 is extended to prevent the cooling tank 101 from moving upward.

[0031] Furthermore, a filter basket 3 is installed in the liquid storage tank 1, and a second filter cotton 301 is placed in the filter basket 3. A cover plate 302 is provided between the side of the filter basket 3 near the circulation pump 4 and the liquid storage tank 1. A second hose 402 is connected to the water inlet end of the circulation pump 4. One end of the second hose 402 passes through the cover plate 302 and extends into the liquid storage tank 1. The second filter cotton 301 can further filter the coolant flowing to the second hose 402. The second filter cotton 301 can be removed from the filter basket 3 by pulling it upward, which makes it easy to clean or replace the second filter cotton 301.

[0032] The second hose 402 and the connecting pipe 107 are located on both sides of the liquid storage tank 1, so as to reduce the situation where the second hose 402 directly draws back hot coolant.

[0033] Furthermore, a thermometer 5 is installed on the side of the liquid storage tank 1 near the circulating pump 4. The probe of the thermometer 5 extends into the liquid storage tank 1. The thermometer 5 can monitor the temperature of the coolant in the area near the second hose 402 in the liquid storage tank 1. When the temperature is too high, the low-temperature coolant can be replaced. The replaced coolant is not discarded directly, but stored in a container to cool naturally for reuse. The thermometer 5 is an existing component, and its specific structure and principle are existing technologies, which will not be described in detail in this application.

[0034] Furthermore, several fans 2 are provided between the liquid storage tank 1 and the cooling tank 101. Each fan 2 has a slot 201 at its top and bottom. The slot 201 at the bottom of the fan 2 is inserted into the side wall of the liquid storage tank 1. A retaining plate 202 is inserted into the slot 201 at the top of the fan 2 and is fixedly connected to the bottom of the cooling tank 101. The arrangement of the fans 2 can accelerate the airflow speed above the liquid storage tank 1, thereby expelling the hot air of the coolant and accelerating the cooling speed of the coolant. Since the fans 2 are engaged and limited by the slots 201 and the retaining plate 202, the fixation of the fans 2 can be released when the cooling tank 101 is removed. The fans 2 can be removed for inspection or replacement by pulling them upward.

[0035] Furthermore, two baffles 203 are installed on the top of the liquid storage tank 1, and several fans 2 are located between the two baffles 203. The baffles 203 are used to limit the movement of the fans 2 on both sides.

[0036] Furthermore, a second drain valve 111 is provided on one side of the liquid storage tank 1. The second drain valve 111 is used to drain the coolant in the liquid storage tank 1 for the purpose of replacing the coolant. The liquid storage capacity of the liquid storage tank 1 is at least four times the liquid storage capacity of the cooling tank 101.

[0037] The cooling pool 101 is welded together with the third fixing seat 406 and the insert rod 110. The L-shaped plate 104 is welded together with the filter pool 105. The filter basket 3 and the first fixing seat 401 are both connected to the liquid storage pool 1 by welding. The cover plate 302 is welded together with the filter basket 3. The clamping plate 202 is welded to the bottom of the cooling pool 101.

[0038] In use, the circulating pump 4 delivers the coolant in the storage tank 1 to the universal bamboo joint tube 404 through the second hose 402 and the third hose 403. Then, the coolant enters the cooling tank 101 through the universal bamboo joint tube 404. The coolant in the cooling tank 101 flows into the filter tank 105 through the first drain valve 102 and the first hose 103. After being filtered by the first filter cotton 106, it enters the storage tank 1 through the connecting pipe 107. After being filtered by the second filter cotton 301, it reaches the second hose 402. The welded product is placed in the cooling tank 101 and cooled by the coolant sprayed from the universal bamboo joint tube 404.
