Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1: Refer to the attached drawings of the specification Figure 1 , 2 , 3, 4, and 5, a welding device for the production and processing of aluminum alloy profiles, comprising: a base 1, a clamping seat 11, and a welding mechanism 12; the welding mechanism 12 is arranged at the four corner positions of the base 1; a clamping block 13 is slidably connected to the clamping seat 11, and a clamping motor 14 is fixedly connected to the clamping seat 11; the output end of the clamping motor 14 is fixedly connected to a lead screw that is in threaded cooperation with the clamping block 13;

[0037] A detection mechanism and an adjustment mechanism are arranged on the base 1; the clamping seat 11 is installed on the base 1 through the adjustment mechanism. After the aluminum alloy profile is clamped on the clamping seat 11 and the clamping block 13, the detection mechanism detects the positions of adjacent aluminum alloy profiles, and the adjustment mechanism adjusts the position of the clamping seat 11 so that the aluminum alloy profile on the clamping seat 11 is aligned with the adjacent aluminum alloy profile, facilitating the welding mechanism 12 to perform welding.

[0038] In the present invention, the detection mechanism includes a sliding block 21, a longitudinal detection block 22, a height detection block 23, and a lateral detection block 24; the sliding block 21 is slidably connected to the base 1; a sliding motor 25 is fixedly connected to the base 1; the output end of the sliding motor 25 is fixedly connected to a lead screw that is in threaded cooperation with the sliding block 21; the longitudinal detection block 22 is fixedly connected to the sliding block 21, and longitudinal detection grooves 26 are symmetrically formed on the longitudinal detection block 22; a longitudinal pressure sensor 27 is fixedly connected in the longitudinal detection groove 26, and a longitudinal detection rod 28 is slidably connected in the longitudinal detection groove 26; a longitudinal spring 29 is fixedly connected between the longitudinal detection rod 28 and the longitudinal pressure sensor 27;

[0039] The height detection block 23 is slidably connected to the longitudinal detection block 22; a height electric push rod 3 is fixedly connected between the longitudinal detection block 22 and the height detection block 23; a pair of height detection grooves 31 are formed on the height detection block 23; a height pressure sensor 32 is fixedly connected in the height detection groove 31; a height detection rod 33 is slidably connected in the height detection groove 31; a height spring 34 is fixedly connected between the height detection rod 33 and the height pressure sensor 32;

[0040] The lateral detection block 24 is installed on the height detection block 23; a lateral electric push rod 35 is fixedly connected to the lateral detection block 24; the output end of the lateral electric push rod 35 is fixedly connected to a lateral detection rod 36; a pair of cross bars 37 are rotatably connected to the end of the lateral detection rod 36; a lateral pressure sensor 38 is fixedly connected to the lateral detection rod 36; a lateral spring 39 is fixedly connected between the lateral pressure sensor 38 and the cross bar 37.

[0041] In the present invention, the adjusting mechanism includes a lifting block 4, a longitudinal moving block 41 and a transverse moving block 42; a lifting electric push rod 43 is fixedly connected to the base 1; the lifting block 4 is fixedly connected to the output end of the lifting electric push rod 43; the longitudinal moving block 41 is longitudinally slidably connected to the lifting block 4; a longitudinal moving motor 44 is fixedly connected to the lifting block 4; the output end of the longitudinal moving motor 44 is fixedly connected to a lead screw that is in threaded cooperation with the longitudinal moving block 41; the transverse moving block 42 is transversely slidably connected to the longitudinal moving block 41; a transverse moving motor 45 is fixedly connected to the longitudinal moving block 41; the output end of the transverse moving motor 45 is fixedly connected to a lead screw that is in threaded cooperation with the transverse moving block 42; the clamping seat 11 is fixedly connected to the transverse moving block 42.

[0042] In the present invention, the staff places the aluminum alloy profile on the clamping seat 11, and then controls the clamping motor 14 through the controller to drive the corresponding lead screw to rotate, so that the clamping block 13 clamps the aluminum alloy profile. Then, the sliding motor 25 drives the corresponding lead screw to rotate, so that the sliding block 21 drives the longitudinal detection block 22, the height detection block 23 and the transverse detection block 24 to move. As a result, the two longitudinal detection rods 28 on the longitudinal detection block 22 are respectively in contact with the two aluminum alloy profiles, so that the two longitudinal detection rods 28 compress the longitudinal spring 29, and the pressures received by the two longitudinal pressure sensors 27 are brought into the stiffness coefficient formula of the longitudinal spring 29, thereby calculating the deviation of the positions of the two aluminum alloy profiles in the longitudinal direction.

[0043] Subsequently, the height electric push rod 3 pulls down the height detection block 23, so that the two height detection rods 33 on the height detection block 23 are respectively in contact with the two aluminum alloy profiles, and then the deviation of the positions of the two aluminum alloy profiles in the vertical direction is calculated.

[0044] Then, the transverse electric push rod 35 on the transverse detection block 24 pushes down the transverse detection rod 36, so that the cross bars 37 on both sides of the transverse detection rod 36 are in contact with the two aluminum alloy profiles, and the transverse detection rod 36 is inserted into the gap between the two aluminum alloy profiles. As a result, the cross bar 37 rotates upward due to contact with the aluminum alloy profile, thereby compressing the transverse spring 39, so that the transverse pressure sensor 38 is subjected to pressure. According to the fact that the pressure of the transverse pressure sensor 38 is different when the cross bar 37 rotates at different angles, the rotation angle of the cross bar 37 can be calculated, and then according to the angle, the distance between the transverse detection rod 36 and the two aluminum alloy profiles can be calculated, thereby obtaining the transverse gap between the two aluminum alloy profiles.

[0045] After the detection is completed, the longitudinal detection block 22, the height detection block 23 and the transverse detection block 24 return to their original positions. Subsequently, the lifting electric push rod 43 drives the lifting block 4 to move, adjusting the vertical position of the aluminum alloy profile so that the two aluminum alloy profiles are aligned in the vertical height. Then, the transverse movement motor 45 and the longitudinal movement motor 44 drive the corresponding lead screws to rotate respectively, adjusting the transverse position and the longitudinal position of the aluminum alloy profile so that the two aluminum alloy profiles are aligned with each other. Subsequently, the welding mechanism 12 welds the aluminum alloy profiles;

[0046] In the present invention, the detection mechanism is provided to detect the position difference of the aluminum alloy profile on the clamping seat 11 in the transverse, longitudinal and vertical directions. Subsequently, the adjustment mechanism adjusts the position of one of the aluminum alloy profiles so that the two aluminum alloy profiles are aligned with each other, thereby completing the position adjustment of the aluminum alloy profiles and thus eliminating the need for manual adjustment.

[0047] Refer to the attached drawings of the specification Figure 7 In the present invention, the transverse detection block 24 is rotatably connected to the height detection block 23.

[0048] In the present invention, a contact rod 46 is slidably connected to the longitudinal detection rod 28.

[0049] In the present invention, the end of the aluminum alloy profile is generally cut into a square or an inclined shape. When the end of the aluminum alloy profile is cut into an inclined shape, when aligning the two aluminum alloy profiles, the inclined end faces of the two aluminum alloy profiles need to be aligned so that a right angle is formed between the two aluminum alloy profiles. At this time, when the cross bar 37 on the transverse detection block 24 detects the distance between the two aluminum alloy profiles, the transverse detection block 24 is rotated so that the cross bar 37 is perpendicular to the inclined surface of the aluminum alloy profile, thereby preventing the angle between the cross bar 37 and the distance between the two aluminum alloy profiles from affecting the detection result;

[0050] In the present invention, the staff can slide the contact rod 46 to adjust the position of the contact rod 46 to adapt to the position of the end of the aluminum alloy profile.

[0051] Embodiment 2: On the basis of Embodiment 1, refer to the attached drawings of the specification Figure 6 In the present invention, a top block 5 is provided on the height detection block 23; a spring switch 51 is fixedly connected inside the top block 5; a top rod 52 is slidably connected to the top block 5; a top moving spring 53 is fixedly connected between the top rod 52 and the top block 5.

[0052] In the present invention, a top groove 54 is formed on the height detection block 23; the top block 5 is slidably connected in the top groove 54; a top moving motor 55 is fixedly connected in the top groove 54; the output end of the top moving motor 55 is fixedly connected with a lead screw that is in threaded cooperation with the top block 5.

[0053] In the present invention, the top rod 52 is made of an elastic material.

[0054] In the present invention, after the position of the aluminum alloy profile is adjusted, the height detection block 23 moves downward, causing the ejector rod 52 to contact the aluminum alloy profile. The ejector rod 52 presses the spring switch 51, and then drives the corresponding lead screw to rotate by pushing the motor 55, causing the top block 5 to drive the ejector rod 52 to move. The ejector rod 52 moves on the two aluminum alloy profiles. When there is an error in the position adjustment between the two aluminum alloy profiles, leaving a gap between the two aluminum alloy profiles, when the ejector rod 52 passes through the gap, it inserts into the gap, thus releasing the spring switch 51, and then detecting that there is a gap between the two aluminum alloy profiles. Subsequently, the position of the aluminum alloy profile is adjusted again;

[0055] In the present invention, by providing the ejector rod 52, the ejector rod 52 detects whether there is a gap between the aluminum alloy profiles after the position of the aluminum alloy profiles is adjusted, thereby preventing the situation where the lateral detection rod 36 detects inaccurately, resulting in a gap between the aluminum alloy profiles during adjustment.

[0056] Embodiment 3: A welding method for the production and processing of aluminum alloy profiles, which is applicable to the above-mentioned welding device for the production and processing of aluminum alloy profiles. The steps of this method are as follows:

[0057] S1. The two longitudinal detection rods 28 on the longitudinal detection block 22 are respectively in contact with the two aluminum alloy profiles. Subsequently, the height electric push rod 3 pulls the height detection block 23 downward, so that the two height detection rods 33 on the height detection block 23 are respectively in contact with the two aluminum alloy profiles. Then, the lateral electric push rod 35 on the lateral detection block 24 pushes the lateral detection rod 36 downward, so that the cross bars 37 on both sides of the lateral detection rod 36 are in contact with the two aluminum alloy profiles, thereby detecting the position differences of the aluminum alloy profiles in the lateral, longitudinal, and vertical directions;

[0058] S2. The adjustment mechanism adjusts the position of the aluminum alloy profile according to the detection result. Then, the ejector rod 52 moves between the two aluminum alloy profiles to detect whether there is a gap between the aluminum alloy profiles;

[0059] S3. The welding mechanism 12 welds the aluminum alloy profiles to make the aluminum alloy profiles into doors and windows.

[0060] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed; the scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
