Technical Field

[0001] This invention belongs to the field of laser welding technology, specifically a heat flow sensor welding device. Background Technology

[0002] Heat flow sensors are the basic tools for measuring heat transfer (heat flux density or heat flux) and the most critical components of a heat flow meter. When heat flows through the sensor, the heat causes a temperature change in the thermocouple or thermistor, which in turn causes a change in the resistance value or potential difference. By measuring the change in resistance value or potential difference, the magnitude of the heat flow can be calculated. Laser welding equipment is required for welding during the production of heat flow sensors.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 6As shown in the embodiment of the present invention, a heat flow sensor welding device includes a housing 1 and a waste gas guiding component. The waste gas guiding component includes a gas guide pipe 2, a working plate 3, and a drive motor 4. The gas guide pipe 2 is rotatably mounted on the inner wall of the housing 1, and the working plate 3 is fixedly mounted on the outer wall of the gas guide pipe 2. The outer wall of the working plate 3 is in close contact with the inner wall of the housing 1. The drive motor 4 is fixedly mounted on one side of the housing 1, and the output end of the drive motor 4 is fixedly connected to one end of the gas guide pipe 2. The waste gas guiding component drives the gas guide pipe 2 to rotate the working plate 3 through the drive motor 4. When the working plate 3 rotates, it can guide the waste gas generated during welding inside the housing 1. Positioning clamps 5 are symmetrically arranged above and below the working plate 3, and a laser welding head is arranged on the top of the housing 1. During welding, the working plate 3 is in a horizontal state. Under the action of the working plate 3, the interior of the housing 1 is divided into two spaces, which are used to guide the heat flow to be welded. The sensor is fixed between two positioning fixtures 5 above the work plate 3. Then, the laser welding head is started to weld the heat flow sensor. The fumes generated during welding will remain in the space above the work plate 3. After the welding is completed, the drive motor 4 starts to work. Under the action of the drive motor 4, the air guide pipe 2 is rotated. When the air guide pipe 2 rotates, it will drive the work plate 3 and the welded heat flow sensor to rotate together. When the work plate 3 rotates, it will guide the fumes to move. When the work plate 3 rotates 180 degrees, the fumes will be guided to the bottom of the box 1, so as to facilitate the treatment of the welding fumes. After the work plate 3 has rotated, the positioning fixture 5 originally located at the bottom will move to the top. At this time, the heat flow sensor on the positioning fixture 5 that has rotated to the top can be replaced, and the welding work can continue. Thus, the device can continue welding work while treating the fumes, so as to ensure the working efficiency of the device.

[0037] like Figures 1 to 4 As shown, a gas guide seat 6 is fixedly installed at the bottom of the housing 1, and a guide plate 7 is fixedly installed at the bottom of the gas guide seat 6. A purification treatment box 8 is provided on one side of the housing 1. The outer wall of the purification treatment box 8 is fixedly connected to the end of the guide plate 7 away from the gas guide seat 6. The housing 1 is connected to the purification treatment box 8 through the gas guide seat 6 and the guide plate 7. When the welding fumes are guided to the bottom of the housing 1, the fumes will pass through the bottom of the housing 1 and enter the gas guide seat 6. Then the fumes will enter the guide plate 7 through the gas guide seat 6. After entering the guide plate 7, the fumes will enter the purification treatment box 8 through the channel inside the guide plate 7. Finally, the welding fumes are purified by the action of the purification treatment box 8 to prevent the fumes from being directly discharged and affecting the surrounding environment.

[0038] like Figures 1 to 9As shown, an air pump 9 is fixedly installed on the side of the housing 1 away from the drive motor 4. A connecting pipe 10 is fixedly installed on the inner wall of the air pump 9. A rotary seal 11 is fixedly installed on the end of the connecting pipe 10 away from the air pump 9. The inner wall of the rotary seal 11 is fixedly connected to the end of the air guide pipe 2 away from the drive motor 4. Several jet nozzles 12 are symmetrically fixedly installed on the inner wall of the air guide pipe 2. The outer wall of the jet nozzles 12 is fixedly connected to the inner wall of the working plate 3. When the working plate 3 rotates 180 degrees, the air pump 9 starts to work. Under the action of the air pump 9, airflow is generated and transported to the inner wall of the air guide pipe 2 through the connecting pipe 10 and the rotary seal 11. After entering the air guide pipe 2, the airflow is ejected through the jet nozzles 12. The airflow ejected through the jet nozzles 12 guides the welding fumes generated inside the housing 1 to move together in the direction of the air guide seat 6, thereby ensuring that the welding fumes can be effectively transported to the interior of the purification treatment box 8, thus ensuring the purification effect of the device on the fumes.

[0039] like Figures 1 to 7 As shown, a set of positioning brackets 13 are symmetrically fixedly installed on the top and bottom of the work plate 3. A clamp seat 14 is slidably installed between the outer walls of each set of positioning brackets 13. The bottom of the upper clamp seat 14 is in contact with the top of the work plate 3. The positioning clamp 5 is slidably installed on the inner wall of the clamp seat 14. Several vent holes 15 are opened on the top of the clamp seat 14, and the several vent holes 15 are staggered from several jet nozzles 12. The clamp seat 14 is slidably installed on the positioning brackets 13. When the work plate 3 is in a horizontal state for welding and fume treatment, the upper clamp seat 14 is in contact with the work plate 3 under the action of gravity, thereby blocking the upper jet nozzles 12. At this time, when the air pump 9 is working, the airflow will not be ejected through the upper jet nozzles 12, thus avoiding the ejected airflow from affecting the welding work. The lower clamp seat 14 will slide along the positioning brackets 13 under the action of gravity. The device slides down, separating the fixture seat 14 from the work plate 3. At this time, the lower jet head 12 is in the open state. Therefore, when the air pump 9 is working, the airflow will be ejected through the lower jet head 12, thereby transporting the flue gas below to the purification treatment box 8. In addition, when the lower fixture seat 14 slides down along the positioning bracket 13, it will slide down with the welded heat flow sensor through the positioning fixture 5. At this time, when the airflow is ejected through the lower jet head 12, the welded heat flow sensor can be cooled by air, thereby avoiding burns to the staff due to overheating of the heat flow sensor when replacing it. In addition, this device can perform air cooling while welding, thereby avoiding the need to wait for the heat flow sensor to cool down before replacement after each welding operation, which is a traditional device, thus improving the working efficiency of the device. The ventilation hole 15 opened on the fixture seat 14 facilitates the passage of airflow, thereby better transporting flue gas and performing air cooling.

[0040] like Figures 1 to 10As shown, the top and bottom of the working plate 3 are symmetrically hinged with gas-gathering plates 16. The outer wall of the upper gas-gathering plate 16 is in contact with the inner wall of the box 1. When the working plate 3 rotates, it will drive the gas-gathering plate 16 to rotate together. When the gas-gathering plate 16 is at the bottom, it will rotate under the action of gravity. Under the action of the gas-gathering plate 16, the flue gas guided to the bottom of the box 1 can be gathered in the middle. At the same time, under the action of the gas-gathering plate 16, a narrower channel appears under the working plate 3, so that the airflow can better act on the flue gas when it is ejected from the jet head 12, ensuring that the flue gas can enter the purification treatment box 8 along the airflow, thereby increasing the purification effect of the device.

[0041] like Figures 1 to 11 As shown, a top block 17 is symmetrically slidably installed on the inner wall of the housing 1. An elastic element A18 is symmetrically fixed between the outer wall of the top block 17 and the inner wall of the housing 1. A locking block 19 is symmetrically slidably installed on the inner wall of the working plate 3. An elastic element B20 is fixed between the outer wall of the locking block 19 and the inner wall of the working plate 3. A slot is provided on the inner wall of the air-gathering plate 16, and the upper air-gathering plate 16 is slidably connected to the locking block 19 through the slot. During the rotation of the working plate 3, when the working plate 3 rotates to the top block 17, the working plate 3 will... The top block 17 is squeezed to cause the elastic element A18 to contract. At this time, the top block 17 will enter the inner wall of the housing 1. As the working plate 3 continues to rotate, the top block 17 will align with the locking block 19. At this time, the top block 17 will squeeze the locking block 19 to move the locking block 19. After the locking block 19 moves, it no longer limits the gas gathering plate 16. This means that when the working plate 3 rotates to the horizontal, the two gas gathering plates 16 located below will flip down at the same time, thereby gathering the flue gas below towards the middle to ensure the subsequent treatment effect of the flue gas.

[0042] like Figures 1 to 12 As shown, sliding plates 21 are symmetrically slidably installed on the inner wall of the air-gathering plate 16. An extension plate 22 is fixedly installed between the outer walls of the two corresponding sliding plates 21. The outer wall of the extension plate 22 is slidably connected to the outer wall of the air-gathering plate 16, and the outer wall of the extension plate 22 is in contact with the inner wall of the box 1. When the air-gathering plate 16 is flipped downwards, due to the influence of the pivot point position, the air-gathering plate 16 can no longer be in contact with the inner wall of the box 1. At this time, under the action of gravity, the extension plate 22 will extend outwards through the sliding plates 21, so that the extension plate 22 always remains in contact with the inner wall of the box 1, thereby ensuring the air-gathering effect when the air-gathering plate 16 is flipped downwards.

[0043] like Figures 1 to 7As shown, an elastic buffer plate 23 is fixedly installed on the inner wall of the positioning bracket 13. The clamp seat 14 located below overlaps the top of the elastic buffer plate 23 located below. A set of limiting blocks 24 are symmetrically fixedly installed on the top and bottom of the working plate 3. The two sets of limiting blocks 24 located below respectively abut against the two air-gathering plates 16 located below. When the clamp seat 14 slides down under the action of gravity, the clamp seat 14 will slide onto the elastic buffer plate 23. The elastic buffer plate 23 buffers the impact force to prevent the device and heat flow sensor from malfunctioning. The limiting blocks 24 limit the air-gathering plate 16, so that the air-gathering plate 16 after being flipped down tilts to both sides to ensure that the air-gathering plate 16 can be flipped to both sides to reset when it rotates to the top.

[0044] like Figures 1 to 4 As shown, a welding box 25 is fixedly installed on the top of the housing 1, and a drive assembly is fixedly installed on the inner wall of the welding box 25. The laser welding head is fixedly connected to the drive assembly, and a sealing door 26 is hinged to the outer wall of the housing 1. During welding, the drive assembly inside the welding box 25 adjusts the position of the laser welding head. Once the position of the laser welding head is adjusted, the laser welding head can be started to perform welding. After welding is completed, the welding box 25 will automatically close to prevent the fumes from being interfered with by the welding box 25 during the guidance process. The sealing door 26 can be opened to operate inside the housing 1. When the housing 1 is performing welding, the sealing door 26 is closed to prevent the fumes generated during welding from leaking out.

[0045] like Figures 1 to 2 As shown, a transparent observation window 27 is fixedly installed on the inner wall of the sealed door 26, and a groove 28 is opened on the outer wall of the sealed door 26. A base plate 29 is fixedly installed at the bottom of the purification treatment box 8. Support legs 30 are symmetrically fixedly installed between the top of the base plate 29 and the bottom of the box 1. Auxiliary support blocks 31 are symmetrically fixedly installed between the top of the purification treatment box 8 and the outer wall of the box 1. When the device is working, the transparent observation window 27 facilitates the observation of the working status inside the device, the groove 28 facilitates the opening of the sealed door 26, the base plate 29 is used to support the device and ensure the overall stability of the device, the support legs 30 are used to fix the box 1 so that the box 1 is at a suitable working height for easy use of the device, and the auxiliary support blocks 31 connect the box 1 and the purification treatment box 8 to further fix the box 1.

[0046] Working Principle: During welding, the working plate 3 is in a horizontal position, dividing the interior of the housing 1 into two spaces. The heat flow sensor to be welded is fixed between the two positioning fixtures 5 above the working plate 3. Then, the laser welding head is activated to weld the heat flow sensor. The fumes generated during welding remain in the space above the working plate 3. After welding is completed, the drive motor 4 starts working, driving the air guide pipe 2 to rotate. The rotation of the air guide pipe 2 causes the working plate 3 and the welded heat flow sensor to rotate together. The rotation of the working plate 3 guides the fumes. When the working plate 3 rotates 180 degrees, the fumes are guided... When the welding fumes are guided to the bottom of the housing 1, they pass through the bottom of the housing 1 and enter the air guide seat 6. Then, the fumes enter the guide plate 7 through the air guide seat 6. After entering the guide plate 7, the fumes will enter the purification treatment box 8 through the channel inside the guide plate 7. Finally, the purification treatment box 8 will purify the welding fumes and prevent the fumes from being directly discharged and affecting the surrounding environment. After the working plate 3 is rotated, the positioning fixture 5, which was originally located at the bottom, will move to the top. At this time, the heat flow sensor on the positioning fixture 5 that has been rotated to the top can be replaced, and the welding work can continue. This allows the device to continue welding work while treating the fumes, ensuring the working efficiency of the device.

[0047] When the work plate 3 rotates 180 degrees, the air pump 9 starts working. Under the action of the air pump 9, airflow is generated and delivered to the inner wall of the air guide pipe 2 through the connecting pipe 10 and the rotating seal 11. After entering the air guide pipe 2, the airflow is ejected through the jet nozzle 12. The fixture seat 14 is slidably mounted on the positioning bracket 13. When the work plate 3 is in a horizontal state for welding and fume treatment, the upper fixture seat 14 adheres to the work plate 3 under the action of gravity, thus blocking the upper jet nozzle 12. At this time, when the air pump 9 is working, the airflow will not be ejected through the upper jet nozzle 12, thereby preventing the ejected airflow from affecting the welding work. The lower fixture seat 14 slides down the positioning bracket 13 under the action of gravity, thus separating the fixture seat 14 from the work plate 3. At this time, the lower jet nozzle 12 is in the open state, so when the air pump 9 is working, the airflow will be ejected through the lower jet nozzle 12. The airflow ejected from the jet nozzle 12 guides the welding fumes inside the housing 1 towards the air intake seat 6, ensuring that the welding fumes are effectively transported to the interior of the purification treatment box 8, thereby guaranteeing the purification effect of the device on the fumes. In addition, when the clamp seat 14 slides down along the positioning bracket 13, it will slide down with the welded heat flux sensor through the positioning clamp 5. At this time, when the airflow is ejected through the jet nozzle 12, the welded heat flux sensor can be cooled by air, thus avoiding burns to the staff due to overheating of the heat flux sensor when replacing it. In addition, this device can perform air cooling while welding, thus avoiding the need to wait for the heat flux sensor to cool down before replacement after each welding operation, which is a traditional device, improving the working efficiency of the device. The ventilation hole 15 opened on the clamp seat 14 facilitates the passage of airflow, thereby better transporting fumes and performing air cooling.

[0048] When the working plate 3 rotates, it drives the air-gathering plate 16 to rotate as well. During the rotation of the working plate 3, when the working plate 3 rotates to the top block 17, the working plate 3 will squeeze the top block 17, causing the elastic element A18 to contract. At this time, the top block 17 will enter the inner wall of the box 1. As the working plate 3 continues to rotate, the top block 17 will align with the locking block 19. At this time, the top block 17 will squeeze the locking block 19, causing the locking block 19 to move. After the locking block 19 moves, it no longer limits the air-gathering plate 16, which means that when the working plate 3 rotates to the horizontal position, the two air-gathering plates 16 located below will flip downwards simultaneously. Under the action of the air-gathering plates 16, the air can be guided into the box. The flue gas at the bottom gathers towards the center, and under the action of the gas-gathering plate 16, a narrower channel appears below the working plate 3, so that the airflow can better act on the flue gas when it is ejected from the jet head 12, ensuring that the flue gas can enter the purification treatment box 8 along the airflow, thereby increasing the purification effect of the device. When the gas-gathering plate 16 flips downward, due to the influence of the pivot point position, the gas-gathering plate 16 can no longer be in contact with the inner wall of the box 1. At this time, under the action of gravity, the extension plate 22 will extend outward through the sliding plate 21, so that the extension plate 22 always stays in contact with the inner wall of the box 1, thereby ensuring the gas-gathering effect when the gas-gathering plate 16 flips downward.
