Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy door and window frame processing equipment, and in particular to automatic processing equipment for aluminum alloy door and window frames. Background Art

[0002] The frames of existing aluminum alloy doors and windows are usually composed of multiple aluminum profiles. In order to achieve a seamless effect on the frame surface, the aluminum profiles need to be welded by automatic welding processing equipment and then polished to make the welding positions smooth.

[0003] Referring to the technical solution previously disclosed by the applicant and published as CN118492739A, the technical solution includes a clamping platform and a welding device for welding aluminum profiles into frames, the clamping platform includes a clamping base and four clamping units arranged on the clamping base; the clamping units all include a clamping mechanism, the clamping mechanism includes a pre-clamping mechanism and a clamping mechanism, the clamping mechanism includes a lower main clamping block, an upper main clamping block located above the lower main clamping block, and a main clamping drive structure for driving the upper main clamping block to move up and down relative to the lower main clamping block, a profile clamp for clamping the aluminum profile is formed between the upper main clamping block and the lower main clamping block, the pre-clamping mechanism is configured to apply a clamping force to the aluminum profile after the aluminum profile is placed in the profile clamping block and when the clamping mechanism does not lock the aluminum profile, thereby eliminating the trouble of traditional manual operation required to apply clamping force, facilitating workers to adjust the angle between the aluminum profiles, and achieving the purpose of improving the production efficiency of the frame.

At this time, the locking pin spring 52 drives the head of the pre-clamping locking pin 51 to be inserted into the frame locking hole 321 and the locking pin protrusion 511 to be inserted into the locking pin limiting groove 391, so that the frame placing lever 39 cannot move. After the frame is removed, the pre-clamping locking pin 51 is manually pulled out by the locking pin lever 512, so that the head of the pre-clamping locking pin 51 is separated from the frame locking hole 321 and the locking pin protrusion 511 is separated from the locking pin limiting groove 391. Then, the pre-clamping locking pin 51 is rotated at a certain angle so that the locking pin protrusion 511 is staggered with the locking pin limiting groove 391. At this time, after releasing the locking pin lever 512, The locking pin spring 52 cannot drive the locking pin protrusion 511 to enter the locking pin limiting groove 391, so that the position of the pre-clamping locking pin 51 on the frame placing lever 39 is relatively fixed, so as to prevent the pre-clamping locking pin 51 from moving toward the second pre-clamping seat 32 during the resetting movement of the frame placing top block 38; then the frame placing lever 39 is used to drive the frame placing top block 38 to reset, and after resetting to the limit surface position at the starting point of the stroke, the pre-clamping locking pin 51 is operated to rotate by the frame placing lever 39, so that the locking pin protrusion 511 corresponds to the locking pin limiting groove 391, so that the locking pin spring 52 can drive the pre-clamping locking pin 51 to be inserted into the pre-clamping locking hole 322, so as to prevent the frame placing lever 39 from being hit by external force during the placement of the aluminum profile, which may cause the frame placing top block 38 to move.

[0053] In this embodiment, there are two clamping platforms 100 and they are arranged in a left-right distribution. The automatic processing equipment also includes a switching linear motion mechanism 201 for driving the welding robot 200 to move between the two clamping platforms 100, an isolation unit 400 arranged between the two clamping platforms 100 to separate them, and a smoking assembly 600 for inhaling welding fumes. The welding robot 200 is installed on the action output end of the switching linear motion mechanism 201.

The switching linear motion mechanism 201, the smoking assembly 600, the isolation unit 400 and the welding fume absorption and processing device are all prior art, and the technical solution of publication number CN118492739A can be specifically referred to.

[0054] Since the technical solution of publication number CN118492739A adopts a valve block reset spring mechanism to drive the valve block linkage rod to control the movement of the valve plate of the valve device, thereby closing the corresponding air inlet end of the smoking three-way pipe 601, this structure is affected by the spring force of the valve block reset spring mechanism, and it is easy for the spring force of the valve block reset spring mechanism to fail to effectively drive the valve block linkage rod to drive the valve plate to close the air inlet end. In order to solve this technical problem, in this embodiment, the smoking component 600 also includes two valve devices and a valve linkage control mechanism, and a valve device is arranged between each smoking hood 602 and the corresponding smoking three-way pipe 601 air inlet end, and the valve device includes a valve seat 603 and a smoking valve plate 604, and the valve seat 603 is installed on the isolation unit 400, and the valve seat 603 is provided with a valve channel 6031 and a valve plate guide groove, the air inlet end of the smoking three-way pipe 601 is connected to the valve seat 603 and corresponds to the air outlet end of the valve channel 6031, and the air outlet end of the smoking hood 602 is installed on the valve seat 603 and corresponds to the air inlet end of the valve channel 6031; the valve plate guide groove is communicated with the valve channel 6031, and the smoking The valve plate 604 is inserted into the valve plate guide groove and can move forward and backward along the valve plate guide groove.

When the smoking port 6041 coincides with the valve channel 6031, the air inlet end of the smoking three-way pipe 601 and the air outlet end of the smoking hood 602 are connected, so that the smoke can enter the welding smoke absorption and treatment device after passing through the smoking hood 602, the valve channel 6031, the smoking port 6041 and the smoking three-way pipe 601; when the smoking port 6041 and the valve channel 6031 are staggered, the smoking valve plate 604 blocks the position between the air outlet end and the air inlet end of the valve channel 6031, thereby disconnecting the air inlet end of the smoking three-way pipe 601 and the air outlet end of the smoking hood 602, so that the smoke cannot enter from the smoking hood 602.

[0055] Further, the valve linkage control mechanism includes a main linkage structure and a slave linkage structure, the main linkage structure includes a linkage chain 605, a linkage sprocket 606, a linkage gear 607, a linkage main shaft 608, two main linkage seats 609 arranged vertically, and two main adjustment seats 610 arranged vertically, the main linkage seat 609 is installed on the rear end of the isolation unit 400, and each main linkage seat 609 is correspondingly provided with a main adjustment seat 610, and the main adjustment seat 610 is installed on the main linkage seat 609 so that the position can be adjusted forward and backward, and the linkage main shaft 608 is vertically arranged and rotatably installed on the two main adjustment seats 610 at both ends.

The driven seat 614 is installed on the isolation unit 400 and is located in front of the main linkage seat 609. For example, the isolation unit 400 is provided with a mounting opening running through both sides of its action, and the driven seat 614 is installed at the mounting opening position; or the driven seat 614 is directly installed at the front end of the isolation unit 400, both of which can realize the installation of the driven seat 614 pre-isolation unit 400.

[0057] Furthermore, the two driven seats 614 are each provided with a rope blocking member 616 for preventing the driven steel wire rope 611 from slipping out of the steel wire rope groove 6121 , thereby ensuring the stability in use.

[0058] When the action output end of the switching linear motion mechanism 201 drives the welding robot 200 to move back and forth between the two clamping platforms 100, the driving rack 202 drives the linkage gear 607 to rotate. In the process of the welding robot 200 moving from the position corresponding to the left clamping platform 100 to the position of the right clamping platform 100, the driving rack 202 moves to the right synchronously with the welding robot 200. In this process, the driving rack 202 links the linkage gear 607 to rotate horizontally along the first direction, so that the linkage gear 607 drives the linkage chain 605 to move, and the linkage chain 605 thereby links the smoking valve plate 604 on the left to move backward, and the smoking port 6041 of the left smoking valve plate 604 is staggered with the valve channel 6031 on the left, so that the air inlet end of the smoking tee 601 corresponding to the left clamping platform 100 is closed; at the same time, when the smoking valve plate 604 on the left moves backward, the driven wire rope 611 drives the smoking valve plate 604 on the right to move forward, so that the smoking port 6041 of the right smoking valve plate 604 overlaps with the valve channel 6031 on the right, so that the air inlet end of the smoking tee 601 corresponding to the right clamping platform 100 is opened, and the welding fume is inhaled. In the process of the welding robot 200 moving from the position corresponding to the right clamping platform 100 to the position of the left clamping platform 100, the driving rack 202 moves to the left synchronously with the welding robot 200. In this process, the driving rack 202 links the linkage gear 607 to rotate horizontally along the first direction, so that the linkage gear 607 drives the linkage chain 605 to move, and the linkage chain 605 thereby links the smoking valve plate 604 on the right to move backward, and the smoking port 6041 of the right smoking valve plate 604 is staggered with the valve channel 6031 on the right, so that the air inlet end of the smoking tee 601 corresponding to the right clamping platform 100 is closed; at the same time, when the smoking valve plate 604 on the right moves backward, the driven wire rope 611 drives the smoking valve plate 604 on the left to move forward, so that the smoking port 6041 of the left smoking valve plate 604 overlaps with the valve channel 6031 on the left, so that the air inlet end of the smoking tee 601 corresponding to the left clamping platform 100 is opened, and the welding fume is inhaled.

[0061] The working method of the automatic processing equipment includes the following steps:

[0062] Step 1: first adjust the height positions of the upper clamping block 222 and the pre-clamping mechanism 3 according to the thickness of the aluminum profile, wherein, after the upper clamping block 222 is adjusted, the distance between the bottom surface of the upper clamping block 222 and the bottom surface of the lower clamping block 223 is at least 5 mm greater than the thickness of the aluminum profile, so that the aluminum profile can be inserted into the profile clamping opening; and after the pre-clamping mechanism 3 is adjusted, the distance between the top surface of the lower clamping block 223 and the lowest point of the pre-clamping pressure wheel 35 is at least 5 mm less than the thickness of the aluminum profile, so that after the aluminum profile is inserted into the profile clamping opening, the pre-clamping pressure wheel 35 can use the spring force of the pre-clamping spring structure to press on the top surface of the aluminum profile;

[0063] Step 2: Put the aluminum profile into the profile clamp. At this time, the aluminum profile pushes the pre-clamping pressure wheel 35 to lift the other end of the pre-clamping swing arm 34 until the pre-clamping pressure wheel 35 presses on the top surface of the aluminum profile. The pre-clamping pressure wheel 35 applies a pre-tightening force to the aluminum profile through the elastic force provided by the pre-clamping spring structure. The pre-tightening force can prevent the aluminum profile from moving easily but does not completely lock the aluminum profile. Then the worker uses a rubber hammer or a wooden hammer to knock and adjust the aluminum profile to adjust the angle between two adjacent aluminum profiles, and then operates the clamping mechanism 22 to completely lock the aluminum profile.

[0064] Step 3: After the positions of the four aluminum profiles are adjusted to form a frame splicing body, the control device is operated to control the welding robot 200 to weld each corner of the frame splicing body according to a preset welding program to form a semi-finished frame; and at this time, the welding fume absorption and processing device is started to absorb the welding fume during the welding process to reduce gas pollution;

[0065] Step 4: After welding is completed, operate the pre-clamping mechanism 3 and the clamping mechanism 22 to release the semi-finished frame, and then move the clamping unit 2 away from the semi-finished frame so that the semi-finished frame can be taken out, completing the unloading of the semi-finished frame on the clamping platform 100.

[0066] This embodiment integrates the pre-clamping mechanism 3 on the clamping mechanism 22, thereby reducing the space occupied, reducing the size and weight of the equipment, and making it less likely to interfere with the operation of workers. In addition, the pre-clamping mechanism 3 can be automatically triggered to apply clamping force to the aluminum profile after the aluminum profile is placed in the profile clamping mouth and when the clamping mechanism 22 is not locked on the aluminum profile, thereby eliminating the trouble of applying clamping force manually in the traditional way, and achieving the purpose of improving the frame production efficiency.

[0067] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
