Technical Field

[0001] This invention relates to the field of condenser fin welding technology, specifically to a fin welding device for automotive condensers. Background Technology

[0002] The condenser is integrated into the front module of the vehicle and is placed at the front of the car. It is part of the air conditioning system. The condenser transfers the energy of the refrigerant to the surrounding environment, turning the high-temperature, high-pressure refrigerant vapor into a high-temperature, high-pressure refrigerant liquid. There are three main types of automotive condensers: tube-fin condensers, parallel flow condensers, and plate-fin condensers. The automotive industry currently mainly uses parallel flow condensers. Several fins and flat tubes are assembled first, and manifolds are installed on both sides, and then welding is carried out.

[0026] Beneficial effects This invention provides a fin welding device for automotive condensers. It has the following advantages: In this invention, a three-step combing assembly is used: First, the height of the combing assembly relative to several fins and flat tubes is adjusted; second, the distance between several combing blocks is adjusted, and several flat tubes are engaged with the bottom of several combing blocks; third, the combing assembly is moved to comb several flat tubes and fins by several combing blocks. This achieves combing of several fins and flat tubes in a vertical state by several combing blocks and readjustment of the spacing, avoiding heat deformation between fins and flat tubes, changes in fin spacing and arrangement during welding, and improving the welding effect of the welding device.

[0027] In this invention, by changing the gap between several combing blocks, the combing of several fins and flat tubes in the vertical state and the readjustment of the spacing are realized to adapt to different fin sizes, thereby improving the adaptability of the combing assembly.

[0028] In this invention, by rotating the two first threaded rods, the first threaded blocks that are threadedly engaged with the peripheral surfaces of the two first threaded rods slide horizontally in the same direction along the two first threaded rods. That is, the two sliding blocks move horizontally along the two horizontal holes, moving closer to or further away from the two first tip clamps. This allows the distance between the two first tip clamps and the two second tip clamps to be adjusted according to the specifications of the parallel flow condenser, achieving alignment between the two first tip clamps and the two ends of the other manifold. This facilitates the clamping and fixing of the two ends of the other manifold and improves the stability of the fin welding process.

[0029] In this invention, the meshing of the main gear with the two first racks drives the two traction plates to move horizontally closer or further apart, thereby adjusting the distance between the two first center clamps and the distance between the two second center clamps. This achieves clamping of both ends of the two manifolds, avoiding gaps between the two manifolds and several flat tubes, and also avoiding the situation where the manifolds jump up directly under clamping force when directly clamping the parallel flow condenser, thus improving the stability and effect of welding.

[0036] Before welding, all components of the assembled parallel flow condenser need to be placed together on the welding table 1, waiting for the welding mechanism at the end of the robotic arm 104 to weld. The parallel flow condenser consists of several fins, several flat tubes and two manifolds. This invention uses the adjustment mechanism 2 in cooperation with the welding table 1 to adjust and clamp the components inside the parallel flow condenser before welding, which facilitates the welding of the welding mechanism. After welding, the combing component 3 is used to comb the welded fins and other structures in a short time.

[0037] The specific adjustment process of the adjustment mechanism 2 is as follows: The manifold is cylindrical. First, the assembled parallel flow condenser is placed on the top of the welding table 1, so that one manifold is placed in the second channel 112 and the other manifold is placed in the first channel 111. Then, the two ends of the manifold placed in the second channel 112 are aligned with the two second tip clamps 208. Next, the two ends of the other manifold are aligned with the two first tip clamps 204. Then, the distance between the two first tip clamps 204 and the distance between the two second tip clamps 208 are adjusted to complete the clamping of the parallel flow condenser by the present invention. Finally, the welding mechanism at the end of the robotic arm 104 is started to perform welding to complete the welding of the parallel flow condenser.

[0038] In addition, to align the two ends of the other manifold with the first center clamps 204 that are slidably fitted on the two traction plates 207, the following operation is required: Start the second motor 110 fixedly mounted on the top of the welding table 1, so that the first transmission mechanism 108 and the second transmission mechanism 109 fitted at the output end of the second motor 110 operate simultaneously. The first transmission mechanism 108 and the second transmission mechanism 109 operate in opposite directions, driving a first threaded rod 102 fitted at the end of the first transmission mechanism 108 to rotate and driving another first threaded rod 102 fitted at the end of the second transmission mechanism 109 to rotate. The two first threaded rods 102 rotate in opposite directions, causing the first threaded blocks 201 threadedly fitted on the circumferential surfaces of the two first threaded rods 102 to slide horizontally in the same direction along the two first threaded rods 102. The bottom of the two first threaded blocks 201 is restricted by the sliding groove 210 opened on the top of the welding station 1, which prevents the two first threaded blocks 201 from deflecting. This causes the sliding mechanism 202 fixedly connected to the side of the two first threaded blocks 201 to move horizontally in the same direction. This causes the sliding blocks 203 fixedly connected to the ends of the two sliding mechanisms 202 to move horizontally in the same direction along the two horizontal holes 2071 respectively. The rectangular blocks 2031 fixedly connected to the top and bottom of the two sliding blocks 203 slide and engage in the two vertical holes 2072 respectively, preventing the two sliding blocks 203 from deflecting. The two sliding blocks 203 slide horizontally along the two horizontal holes 2071 respectively, causing the first center clamp 204 fixedly connected to one side of the two sliding blocks 203 to move horizontally in the same direction, thereby changing the distance between the two first center clamps 204 and the two second center clamps 208. The above method involves rotating the two first threaded rods 102, causing the first threaded blocks 201, which are threadedly engaged with the two first threaded rods 102, to slide horizontally in the same direction along the two first threaded rods 102. That is, the two sliding blocks 203 move horizontally along the two horizontal holes 2071, moving closer to or further away from the two first tip clamps 204. This allows the distance between the two first tip clamps 204 and the two second tip clamps 208 to be adjusted according to the specifications of the parallel flow condenser, achieving alignment between the two first tip clamps 204 and the two ends of the other manifold. This facilitates the clamping and fixing of the two ends of the other manifold and improves the stability of the fin welding process.

[0039] After aligning the two first-center clamps 204 with the two ends of the other manifold, adjust the distance between the two first-center clamps 204 and the distance between the two second-center clamps 208 to achieve the clamping of the parallel flow condenser by the present invention. Specifically, start the first motor 209 fixedly installed at the bottom of the welding table 1 to drive the main gear 2091 fixedly connected to the output end of the first motor 209 to rotate. The rotation of the main gear 2091 drives the two first racks 205 meshing with the circumferential side of the main gear 2091 to move horizontally in opposite directions. The limiting rods 2051 fixed at both ends of the two first racks 205 correspond one-to-one with the several limiting baffles 105 fixed at the bottom of the welding table 1 and slide with each other. The horizontal movement of the two first racks 205 drives the limiting blocks 206 fixed at the top of the two first racks 205 to move horizontally along the rectangular hole 106 through the top of the welding table 1, driving the two limiting blocks... The traction plates 207, fixedly connected to the top of 206, move horizontally closer to or further away from each other along the two rectangular holes 106. This movement is achieved through the meshing of the main gear 2091 with the two first racks 205, which in turn drives the two traction plates 207 to move horizontally closer to or further away from each other. This, in turn, drives the second tip clamps 208, fixedly connected to one side of the two traction plates 207, to move horizontally closer to or further away from each other, and drives the first tip clamps 204, which are slidably fitted on the two traction plates 207, to move horizontally closer to or further away from each other. This adjusts the distance between the two first tip clamps 204 and the distance between the two second tip clamps 208, thus achieving clamping of both ends of the two manifolds. This avoids gaps between the two manifolds and several flat tubes, and also avoids the situation where the manifolds jump up directly under the clamping force when directly clamping the parallel flow condenser, thereby improving the stability and effect of welding.

[0040] The specific combing process of the combing component 3 is as follows: First, adjust the height of the combing component 3 relative to the fins and flat tubes: Activate the cylinder 3081 fixedly installed at the bottom of the support frame 308, causing the mounting top plate 301, which is fixedly connected to the telescopic end of the cylinder 3081, to move up and down. Adjust the distance between the combing block 3051 below the mounting top plate 301 and the flat tubes, so that the flat tubes are engaged at the top of the combing block 3051, facilitating subsequent combing of the flat tubes and fins using the combing component 3; Second, adjust the distance between the combing blocks 3051 and engage the flat tubes at the bottom of the combing blocks 3051: Activate the mounting top plate 301... A third motor 307, fixedly mounted at the bottom, causes the bidirectional threaded rod 3071, fixedly connected to the output end of the third motor 307, to rotate in either the forward or reverse direction. Since the two second threaded blocks 306 are respectively engaged with the two threaded rails on the circumferential side of the bidirectional threaded rod 3071, the rotation of the bidirectional threaded rod 3071 drives the two second threaded blocks 306 to simultaneously move closer or further apart horizontally. Both second threaded blocks 306 move horizontally at the bottom of the mounting plate 301. This horizontal movement of the two second threaded blocks 306 drives the moving blocks 302, fixedly connected to one side of each second threaded block 306, to move closer or further apart horizontally. Several of these moving blocks... Movable blocks 302 are respectively disposed at the bottom of the mounting top plate 301 and located on both sides of the fixed movable blocks 302. Several movable blocks 302 are slidably fitted into two slots at the bottom of the mounting top plate 301. When the movable blocks 302, which are fixedly connected to the two second threaded blocks 306, move horizontally in opposite directions, they cause the several movable blocks 302 to move horizontally at equal intervals. This causes the first cross plate 303 and the second cross plate 304, which are rotatably fitted between the several movable blocks 302, to rotate in opposite directions, thereby causing the vertical plate 30, which is rotatably fitted between the ends of adjacent first cross plates 303 and second cross plates 304, to rotate. 5. The combing block 3051 moves horizontally, that is, it drives several combing blocks 3051 located on both sides of the fixed moving block 302 to move horizontally in opposite directions. During the horizontal movement of several combing blocks 3051, the gap is the same. By changing the gap between several combing blocks 3051, the adaptability of the combing assembly 3 is improved to accommodate different fin sizes. The combing blocks 3051 in the combing assembly 3 comb several fins and flat tubes in the vertical state and readjust the spacing, avoiding heat deformation between fins and flat tubes, changes in fin spacing and arrangement during welding, and improving the welding effect of the welding device.The third step involves moving the combing assembly 3 to comb several flat tubes and fins using several combing blocks 3051. This is achieved by activating the fourth motor 1031 fixedly mounted on the guide rail 103, causing the second threaded rod 1032, fixedly connected to the output end of the fourth motor 1031, to rotate forward or backward. This drives the support frame 308, whose circumferential thread engages with the second threaded rod 1032, to move horizontally along the top of the guide rail 103 in the direction of the second threaded rod 1032. This controls the combing assembly 3 to comb several flat tubes and fins along the direction of the flat tubes. The order of the first and second steps can be adjusted according to the fin condition to improve the fin welding effect.
