Description

Technical Field

[0001] This utility model belongs to the field of corner assembly machine technology, specifically a synchronous corner assembly machine for aluminum doors and windows with automatic cleaning function for edge and corner scraps. Background Technology

[0002] The aluminum door and window synchronous corner assembly machine is a key piece of equipment in the aluminum door and window production process. It is mainly used to connect the cut aluminum profiles through corner brackets and apply synchronous pressure at the corners to achieve precise corner assembly. This ensures the right-angle accuracy, overall flatness, and structural strength of the door and window frame. Its performance directly affects the sealing performance, service life, and appearance quality of aluminum doors and windows. It is widely used in building decoration, home furnishing manufacturing, and other fields. As the aluminum door and window industry increases its requirements for production efficiency and product precision, the automation level and functional completeness of the corner assembly machine have become the focus of industry attention.

[0003] Existing aluminum door and window synchronous corner assembly machines typically consist of the following core components: Positioning mechanism: including profile positioning block, side clamping device, etc., used to accurately fix the aluminum profile to be assembled at the corner in the preset position to ensure the corner connection accuracy; Synchronous corner assembly actuator: Composed of hydraulically or pneumatically driven corner assembly cylinder, corner assembly knife, etc., it can apply synchronous pressure to the two right-angled sides of the aluminum profile, tightly press the corner bracket with the profile, and complete the corner assembly action; Auxiliary adjustment devices, such as profile length positioning rulers and angle fine-tuning mechanisms, are used to adapt to the corner assembly requirements of doors and windows of different specifications and improve the versatility of the equipment.

[0004] The existing corner-assembly machines have the following shortcomings: During the corner assembly process, burrs from aluminum profile cutting and metal scraps from corner code pressing will adhere to the profile surface or accumulate in the gaps of the workbench. Existing equipment does not have an automatic cleaning function, and manual cleaning with tools such as brushes and air guns is required. This not only increases the labor intensity of workers, but also causes the scraps to be mixed into the next corner assembly process if not cleaned in time, resulting in scratches on the profile surface or deviations in corner assembly accuracy. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an aluminum door and window synchronous corner assembly machine with automatic edge and scrap material cleaning function, which solves the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A synchronous corner assembly machine for aluminum doors and windows with automatic edge and scrap material cleaning function, comprising a base, a first fixing block fixedly installed on one side of the top of the base, a positioning block provided inside the first fixing block, a first electric telescopic rod provided on the top of the first fixing block, a pressure plate snapped to the output end of the first electric telescopic rod, a pressure rod fixedly connected to the end of the pressure plate, a second fixing block fixedly installed on the top of the base in a symmetrical structure, a second electric telescopic rod provided inside the second fixing block, a movable block connected to the output end of the second electric telescopic rod, an adjusting rod threadedly connected to the movable block, and an adjusting rod threadedly connected to the outer side of the adjusting rod. The base is connected to a pressing block. A first motor is installed inside the base. A first lead screw is coaxially fixedly connected to the output end of the first motor. A slider is threadedly connected to the outside of the first lead screw. A chamfering block is fixedly connected to the top of the slider. A worktable is provided on the top of the base. A drive mechanism for lifting and lowering the worktable is provided inside the base. A slot is opened in the worktable to cooperate with the first fixing block, the second fixing block, and the chamfering block. A baffle is fixedly installed on the outside of the worktable. A collection box is provided on the outside of the baffle. An exhaust port is opened on the outside of the collection box. A connecting pipe is connected to one side of the exhaust port. A collection cylinder is threadedly connected to the other end of the connecting pipe.

[0007] As a further embodiment of this utility model: the driving mechanism includes a second motor, which is fixed inside one side of the base. A gear set is provided at the output end of the second motor, and a second lead screw is fixedly connected to the top of the gear set. A movable rod is installed on the top of the worktable, and the movable rod is located outside the second lead screw and threadedly connected to the second lead screw.

[0008] As a further embodiment of this utility model: a stop strip is provided at the edge of the slot, and the stop strip is lower than the bottom of the chamfered block.

[0009] As a further embodiment of this utility model: a locking block is provided on the outer side of the baffle to cooperate with the collecting cylinder, and a long suction pipe is provided at the end of the collecting cylinder.

[0010] As a further embodiment of this utility model: a support plate is provided on the outer side of the base in a symmetrical structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The first motor drives the first lead screw to rotate, which in turn moves the slider and chamfering block along the slot to chamfer the fixed workpiece. The debris generated during processing is blocked by the baffle and initially falls into the collection box. The baffle at the edge of the slot prevents the debris from entering the depth of the slot, reducing the cleaning burden. During routine cleaning, the exhaust port is connected to an air pump, which uses negative pressure to suck the debris from the worktable surface and the slot into the collection box. Alternatively, the threaded collection cylinder can be manually adjusted to use the long suction pipe to precisely absorb local residual debris. For deep cleaning, the pressure plate and pressure rod are removed, and the drive mechanism is activated to raise the worktable above each fixed block and chamfering block, making the worktable fully open for thorough cleaning.

Detailed Implementation

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: A synchronous corner assembly machine for aluminum doors and windows with automatic edge and scrap cleaning function includes a base 1. A first fixing block 3 is fixedly installed on one side of the top of the base 1. A positioning block 4 is provided inside the first fixing block 3. A first electric telescopic rod 5 is provided on the top of the first fixing block 3. A pressure plate 7 is snapped to the output end of the first electric telescopic rod 5. A pressure rod 8 is fixedly connected to the end of the pressure plate 7. A second fixing block 9 is fixedly installed on the top of the base 1 in a symmetrical structure. A second electric telescopic rod 10 is provided inside the second fixing block 9. A movable block 11 is connected to the output end of the second electric telescopic rod 10. An adjusting rod 12 is threaded to the inside of the movable block 11. A pressing block 13 is threaded to the outside of the adjusting rod 12. A second fixing block 10 is installed inside the base 1. A motor 14 is provided. The output end of the first motor 14 is coaxially fixedly connected to a first lead screw 15. A slider 16 is threadedly connected to the outside of the first lead screw 15. A chamfer block 17 is fixedly connected to the top of the slider 16. A worktable 101 is provided on the top of the base 1. A drive mechanism for lifting and lowering the worktable 101 is provided inside the base 1. A slot 27 is provided inside the worktable 101 to cooperate with the first fixed block 3, the second fixed block 9 and the chamfer block 17. A baffle 6 is fixedly installed on the outside of the worktable 101. A collection box 18 is provided on the outside of the baffle 6. An exhaust port 19 is provided on the outside of the collection box 18. A connecting pipe 20 is connected to one side of the exhaust port 19. A collection cylinder 21 is threadedly connected to the other end of the connecting pipe 20. Specifically, the workbench 101 is raised and lowered by a drive mechanism to adjust its height. After the positioning block 4 initially positions the workpiece, the first electric telescopic rod 5 drives the pressure rod 8 to vertically press the workpiece. The second electric telescopic rod 10 pushes the movable block 11 closer to the workpiece, which is then fixed from the side in conjunction with the adjusting rod 12 and the pressing block 13. The first motor 14 drives the first lead screw 15 to move the slider 16 and the chamfering block 17 to complete the chamfering of the workpiece. The debris generated during processing is blocked by the baffle 6 and initially falls into the collection box 18. During routine debris cleaning, the exhaust port 19 is connected to an air pump. The negative pressure is used to suck the debris from the surface of the workbench 101 and the slot 27 into the collection box 18 through the opening between the collection box 18 and the baffle 6. For local residual debris, the workbench can be manually rotated. The threaded collection cylinder 21 is adjusted to align with the debris accumulation point. The suction force of the connecting pipe 20 directly draws the debris into the collection cylinder 21, achieving precise cleaning. When the workbench 101 needs to be thoroughly cleaned, first release the buckle connection between the first electric telescopic rod 5 and the pressure plate 7, and remove the pressure plate 7 and the pressure rod 8. Start the drive mechanism to raise the workbench 101 until the first fixing block 3, the second fixing block 9, and the chamfer block 17 are fully exposed in the slot 27 of the workbench 101 (i.e., the workbench 101 is raised above each component). At this time, the surface of the workbench 101 and the slot 27 area are completely open, making it easy to wipe, rinse, or use tools to clean residual debris directly, solving the problem of cleaning dead corners caused by component obstruction under normal conditions. The drive mechanism includes a second motor 23, which is fixed inside the base 1 on one side. A gear set 24 is provided at the output end of the second motor 23. A second lead screw 25 is fixedly connected to the top of the gear set 24. A movable rod 26 is installed on the top of the worktable 101. The movable rod 26 is located outside the second lead screw 25 and is threadedly connected to the second lead screw 25. A stop bar is provided at the edge of the slot 27, and the stop bar is lower than the bottom of the chamfer block 17. A locking block 22 for use with the collecting cylinder 21 is provided on the outside of the baffle 6. A long suction pipe is provided at the end of the collecting cylinder 21. A support plate 2 is provided on the outside of the base 1 in a left-right symmetrical structure. Specifically, after the second motor 23 inside the base 1 starts, it transmits power through the gear set 24, driving the second lead screw 25 fixedly connected to the top to rotate. Since the movable rod 26 installed on the top of the worktable 101 is located outside the second lead screw 25 and is threadedly connected to it, the rotation of the second lead screw 25 will be converted into the up and down movement of the movable rod 26. The stop strip at the edge of the slot 27 is lower than the bottom of the chamfer block 17, which will not affect the normal movement of the chamfer block 17, and can also prevent the debris generated during processing from entering the depth of the slot 27, reducing the cleaning burden. The locking block 22 on the outside of the baffle 6 can limit and fix the material collection cylinder 21. The long suction pipe at one end can reach deep into the corners and crevices of the workbench 101 to more thoroughly absorb debris. In addition, the symmetrical support plates 2 on the outer side of the base 1 enhance the overall stability of the equipment and prevent the equipment from shifting due to vibration during processing. During routine cleaning, the long suction pipe, together with the collection cylinder 21 fixed by the clamping block 22, can accurately clean the debris blocked by the baffle at the edge of the slot 27 under the suction of the air pump. During deep cleaning, the lifting structure of the workbench 101 driven by the second motor 23 can more smoothly raise the workbench 101 to a suitable height. Combined with the long suction pipe, the workbench 101 and the surrounding area can be thoroughly cleaned. The working principle of this utility model is as follows: First, after the worktable 101 is adjusted to a suitable height by the drive mechanism, the positioning block 4 initially positions the workpiece. The first electric telescopic rod 5 drives the pressure rod 8 to vertically press the workpiece, while the second electric telescopic rod 10 pushes the movable block 11 closer to the workpiece. Together with the adjusting rod 12 and the pressing block 13, it is fixed from the side, forming a multi-directional stable constraint to ensure that the workpiece does not shift during processing. Secondly, the first motor 14 drives the first lead screw 15 to rotate, which in turn drives the slider 16 and the chamfering block 17 to move along the slot 27 to perform chamfering on the fixed workpiece. The debris generated during processing is blocked by the baffle 6 and initially falls into the collection box 18. The baffle at the edge of the slot 27 prevents the debris from entering the depth of the slot 27, reducing the cleaning burden. Finally, during routine cleaning, the exhaust vent 19 is connected to an air pump, which uses negative pressure to suck debris from the surface of the workbench 101 and the slots 27 into the collection box 18. Alternatively, the threaded collection cylinder 21 can be manually adjusted to precisely absorb localized residual debris using a long suction pipe. For deep cleaning, the pressure plate 7 and pressure rod 8 are removed, and the drive mechanism is activated to raise the workbench 101 above each fixed block and chamfered block 17, so that the workbench 101 is fully open for thorough cleaning.

[0016] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
