Description

Technical Field

[0001] This invention relates to the field of combined processing technology, specifically to a processing equipment for aluminum alloy corner connectors for curtain walls. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure commonly used in modern large and high-rise buildings for decorative purposes, consisting of panels and a supporting structural system. During curtain wall installation, aluminum alloy corner connectors are required. Aluminum alloy corner connectors are widely used due to their strong corrosion resistance and light weight. However, some problems still exist in the surface polishing process of aluminum alloy corner connectors: Since there are few devices on the market specifically designed for aluminum alloy corner connectors, most of them are polished manually. The polishing process needs to be done twice to polish the upper and lower surfaces of the connectors, which is inefficient. In addition, since the polishing work is often carried out in an open environment, a lot of metal shavings are generated during the polishing process. This not only pollutes the surrounding work environment, but also affects the health of workers if inhaled. Summary of the Invention

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Example 1 Please refer to Figures 1-13As shown, a curtain wall aluminum alloy corner connector processing equipment includes a machine body 1. A robotic arm 101 and a housing 102 are arranged on the top left side of the machine body 1. A first auxiliary mechanism 2 is installed on the rear side of the interior of the housing 102. Two sets of second auxiliary mechanisms 3 are connected to the front side of the interior of the housing 102. Processing mechanisms 4 are installed inside the two sets of second auxiliary mechanisms 3. The first auxiliary mechanism 2, the second auxiliary mechanism 3 and the processing mechanism 4 cooperate to bend, grind, drill, tap and cut the workpiece to form an intermediate body B-1 and a reinforcing rib B-2. A welding mechanism 5 is also installed on the right side of the top of the machine body 1. The welding mechanism 5 is used to weld the intermediate body B-1 and the two sets of reinforcing ribs B-2 together to form a curtain wall aluminum alloy corner connector.

[0019] Example 2 Please refer to Figure 3 and Figure 4 As shown, the first auxiliary mechanism 2 includes a first threaded rod 201 and a first fixed rod 202. The first threaded rod 201 is rotatably connected to the rear side of the inside of the housing 102, and the first fixed rod 202 is fixedly connected to the rear side of the inside of the housing 102. A first servo motor 203 that drives the first threaded rod 201 to rotate is installed on the outer wall of the housing 102. The threads at both ends of the first threaded rod 201 have opposite directions of rotation, and both ends of the outer wall of the first threaded rod 201 are threadedly connected to movable frames 204. Both sets of movable frames 204 are slidably connected to the first fixed rod 202.

[0020] Please refer to Figure 5 As shown, the first auxiliary mechanism 2 also includes a second threaded rod 205 and a second servo motor 207. The second threaded rod 205 is rotatably mounted inside the movable frame 204, and the second servo motor 207 is located on the top of the movable frame 204. The top of the second threaded rod 205 is fixedly connected to the output end of the second servo motor 207. A second fixed rod 206 is also fixedly mounted inside the movable frame 204. Two sets of moving parts 208 are slidably connected to the second fixed rod 206, and the threads at both ends of the second threaded rod 205 have opposite directions. The two sets of moving parts 208 are respectively threaded to the two ends of the outer wall of the second threaded rod 205. A second clamping member 209 is rotatably connected inside the moving part 208. The second clamping member 209 is driven by the output end of the first drive motor 210 provided on the outer wall of the moving part 208.

[0021] Those skilled in the art will understand that by driving the first threaded rod 201 to rotate through the output end of the first servo motor 203, the two sets of movable frames 204 move closer or further apart along the outer wall of the first fixed rod 202, thereby driving the second clamping members 209 on the left and right sides to move closer or further apart; and by driving the output end of the second servo motor 207 to rotate, the second threaded rod 205 is driven to rotate, causing the two sets of second clamping members 209 connected thereto to move closer or further apart; and by driving the output end of the first drive motor 210 to rotate, the second clamping member 209 is driven to rotate, so that the second clamping member 209 can be kept in a horizontal or vertical state.

[0022] Example 3 Please refer to Figure 6 As shown, the second auxiliary mechanism 3 includes a first lead screw 301 and a first guide rod 302. The first lead screw 301 is provided with two sets of components rotatably connected to the front of the inner side of the housing 102. The first guide rod 302 is also provided with two sets of components fixedly installed on the front of the inner side of the housing 102. A first stepper motor 303 for driving the first lead screw 301 to rotate is provided on the outer wall of the housing 102. Two sets of movable parts 304 are threadedly connected to both ends of the outer wall of the first lead screw 301. The movable parts 304 are slidably connected to the first guide rod 302. The threads at both ends of the first lead screw 301 are in opposite directions. A second drive motor 305 is fixedly installed on the outer end of the movable part 304. The output end of the second drive motor 305 is fixedly connected to the second electric push rod 306. A pressure member 307 is fixedly installed on the output end of the second electric push rod 306.

[0023] Those skilled in the art will understand that by driving the first lead screw 301 to rotate through the output end of the first stepper motor 303, the two sets of moving parts 304 move closer or further away from each other along the outer wall of the first guide rod 302, thereby driving the pressing parts 307 to move closer or further away from each other. Furthermore, by driving the output end of the second drive motor 305 to rotate, the second electric push rod 306 and the pressing parts 307 rotate as a whole, thereby changing the tilt angle of the pressing parts 307.

[0024] Example 4 Please refer to Figure 7 , Figure 9 and Figure 10As shown, the processing mechanism 4 includes a second lead screw 401 and a second guide rod 402. The second lead screw 401 is rotatably connected inside the pressure member 307, and the second guide rod 402 is fixedly installed inside the pressure member 307. A second stepper motor 403 that drives the second lead screw 401 to rotate is installed on the outer wall of the pressure member 307. A first movable plate 404 is threadedly connected to the outer wall of the two sets of second lead screws 401 located above, and a second movable plate 411 is threadedly connected to the outer wall of the two sets of second lead screws 401 located below. The second guide rod 402 is used to guide the first movable plate 404 and the second movable plate 411.

[0025] Please refer to Figure 8 , Figure 9 and Figure 10 As shown, two sets of third electric push rods 405 are rotatably connected inside the first movable plate 404. The output ends of the two sets of third electric push rods 405 are fixedly connected to the drill head 406 and the tapping head 407, respectively. Two sets of fourth electric push rods 408 are also fixedly connected inside the first movable plate 404. The output ends of the two sets of fourth electric push rods 408 are fixedly installed with the cutting head 409 and the first grinding plate 410, respectively. Two sets of fifth electric push rods 412 are fixedly installed inside the second movable plate 411. The output ends of the two sets of fifth electric push rods 412 are connected to the second grinding plate 413 and the abutment plate 414, respectively.

[0026] Those skilled in the art will understand that by controlling the output end of the upper second stepper motor 403 to rotate, the upper second lead screw 401 is driven to rotate, causing the first movable plate 404 to reciprocate along the outer wall of the upper second guide rod 402. This achieves the reciprocating motion of the drill head 406, tapping head 407, cutting head 409, and first grinding plate 410 as a whole along the outer wall of the upper second guide rod 402. When not in use, the drill head 406, tapping head 407, cutting head 409, and first grinding plate 410 are all stored inside the upper pressure member 307. When in use, by driving the corresponding output end of the third electric push rod 405 or the fourth electric push rod 408, they extend to the outside of the upper pressure member 307. Figure 8 As can be seen, the rotation of the drilling head 406 and the tapping head 407 is achieved by the cooperation of an electric motor and a gear set, thereby realizing the drilling and tapping of the workpiece; Similarly, by controlling the output end of the second stepper motor 403 located below to rotate, the second lead screw 401 located below will rotate, causing the second movable plate 411 to reciprocate along the outer wall of the second guide rod 402 located below. This enables the second grinding plate 413 and the contact plate 414 to reciprocate along the outer wall of the second guide rod 402 located below. When not in use, the second grinding plate 413 and the contact plate 414 are stored inside the pressure member 307 located below. When in use, the corresponding fifth electric push rod 412 is driven to extend to the outside of the pressure member 307.

[0027] Please refer to Figure 2 and Figure 3 As shown, a first electric push rod 105 is provided on the right side of the housing 102. The output end of the first electric push rod 105 is fixedly connected to a first dual-axis electric push rod 106. Both output ends of the first dual-axis electric push rod 106 are fixedly installed with first clamping parts 107. The bottom of the housing 102 is inclined. A chip outlet is provided through the bottom left side of the housing 102. A cover plate 104 is installed on the outside of the chip outlet. A cylinder 103 is fixedly connected to the outside of the housing 102. The top of the cover plate 104 is fixedly connected to the output end of the cylinder 103.

[0028] Those skilled in the art will understand that by controlling the extension or retraction of the output end of the first electric push rod 105, the first dual-axis electric push rod 106 and the two sets of first clamping members 107 are moved to the left or right as a whole. Furthermore, by controlling the synchronous extension or retraction of the two output ends of the first dual-axis electric push rod 106, the two sets of first clamping members 107 are moved away from or closer to each other. Moreover, by controlling the extension or retraction of the output end of the cylinder 103, the cover plate 104 is moved downward or upward, thereby controlling the closing and opening of the chip outlet.

[0029] Example 5 Please refer to Figure 11 As shown, the welding mechanism 5 includes an L-shaped plate 501 fixedly installed on the rear side of the top of the machine body 1. A support plate 502 is fixedly connected to the front side of the L-shaped plate 501. A sixth electric push rod 503 is fixedly connected to the top of the horizontal plate of the L-shaped plate 501. The output end of the sixth electric push rod 503 passes through the top wall of the horizontal plate of the L-shaped plate 501 and is fixedly connected to the pressure plate 504.

[0030] Those skilled in the art will understand that by controlling the output end of the sixth electric push rod 503 to extend or retract, the pressure plate 504 is driven to move downward or upward. When the pressure plate 504 moves downward, it moves closer to the support plate 502 to clamp and fix the intermediate body B-1. Conversely, when the pressure plate 504 moves upward, it releases the clamping of the intermediate body B-1.

[0031] Please refer to Figure 11 and Figure 12 As shown, the welding mechanism 5 also includes a fixed frame 505 fixedly installed on the front side of the L-shaped plate 501. A third lead screw 506 is rotatably connected inside the fixed frame 505. A moving block 509 is threadedly connected to the outer wall of the third lead screw 506. The moving block 509 is slidably connected to the third guide rod 507. The third guide rod 507 is welded inside the fixed frame 505. The outer end of the third lead screw 506 is fixedly installed on the output end of the third stepper motor 508. The third stepper motor 508 is set on the outer wall of the fixed frame 505. A seventh electric push rod 510 is connected to the outer wall of the moving block 509. A lifting frame 511 is fixedly installed on the output end of the seventh electric push rod 510.

[0032] Please refer to Figure 11 and Figure 13 As shown, a third threaded rod 512 is rotatably connected inside the lifting frame 511. The threads at both ends of the third threaded rod 512 are in opposite directions. A third fixed rod 513 is also fixedly installed inside the lifting frame 511. Two sets of moving plates 515 are slidably connected to the third fixed rod 513. The two sets of moving plates 515 are respectively threaded to both ends of the outer wall of the third threaded rod 512. A third servo motor 514 for driving the third threaded rod 512 to rotate is provided on the outer wall of the lifting frame 511. A second dual-axis electric push rod 516 is fixedly installed inside the moving plate 515. Both output ends of the second dual-axis electric push rod 516 are fixedly connected to the third clamping member 517. A welding robot 518 is also provided on the top rear side of the machine body 1.

[0033] Those skilled in the art will understand that by controlling the two output ends of the second dual-axis electric actuator 516 to extend or retract synchronously, the two sets of third clamping members 517 are driven to move away from or towards each other. When they are close together, the reinforcing rib B-2 is clamped and fixed; conversely, when they are far apart, the reinforcing rib B-2 is released from clamping. The output of the third servo motor 514 drives the third threaded rod 512 to rotate, causing the two sets of moving plates 515 to move closer or further apart. This, in turn, causes the two sets of reinforcing ribs B-2 in the clamping state to move closer or further apart, changing the spacing between the two sets of reinforcing ribs B-2. This allows for the selection of a suitable spacing between the two sets of reinforcing ribs B-2 for installation based on the width of different intermediate bodies B-1. Furthermore, the output of the third stepper motor 508 drives the third lead screw 506 to rotate, causing the moving block 509 to reciprocate back and forth along the outer wall of the third guide rod 507. The movement causes the two sets of reinforcing ribs B-2, which are in a clamping state, to move to the bottom of the intermediate body B-1. In conjunction with the extension of the output end of the seventh electric push rod 510, the two sets of reinforcing ribs B-2 move upward and abut against the corresponding installation position. Finally, the welding robot 518 welds the two sets of reinforcing ribs B-2 together with the intermediate body B-1 to form a curtain wall aluminum alloy corner connector. Due to the presence of the reinforcing ribs B-2, the strength is improved to a certain extent, which further improves the service life of the corner connector.

[0034] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. The workpiece at the end of the external conveyor is clamped by the robotic arm 101 and transferred to the inside of the box 102. The workpiece is a rectangular metal plate, which is placed horizontally along the length of the box 102. In real life, the aluminum alloy corner connector of the curtain wall is a bent part, which looks like "a horizontal plate with symmetrical inclined ear plates connected on both sides of the horizontal plate". Therefore, under the action of the output end of the first servo motor 203 and the output end of the second servo motor 207, the two sets of second clamping parts 209 on the left and right sides are moved to the position where the workpiece is to be bent, and the workpiece is clamped and fixed at the position where it is to be bent. S2. With the cooperation of the output end of the first stepper motor 303, the output end of the second drive motor 305, and the output end of the second electric push rod 306, the two sets of pressure members 307 below are tilted. With the cooperation of the output end of the first stepper motor 303, the output end of the second drive motor 305, and the output end of the second electric push rod 306 above, the two sets of pressure members 307 above press down on the two sides of the workpiece at the bending position, so that the two side plates of the workpiece tilt down at the bending position to form ear plates. When bending, the bending ends when the bottom of the two side ear plates comes into contact with the two sets of tilted pressure members 307 below. Therefore, we can see that the two sets of pressure members 307 below play a bending positioning role. S3. After bending, under the action of the two sets of second auxiliary mechanisms 3, the four sets of pressing parts 307 can move to fit the upper and lower surfaces of the ear plates respectively. During the movement, the first grinding plate 410 and the second grinding plate 413 in the processing mechanism 4 extend and move back and forth along the surface of the ear plate, thereby realizing the comprehensive grinding and polishing of the upper and lower surfaces of the two ear plates, which can be done simultaneously, conveniently and quickly. In addition, when it is necessary to grind the upper and lower surfaces of the middle horizontal plate connecting the two ear plates, the output ends of the two sets of first drive motors 210 on the left are driven to rotate, causing the second clamping part 209 on the upper left to rotate upward and the second clamping part 209 on the lower left to rotate downward. With both sets of second clamping members 209 in a vertical position, the two sets of second clamping members 209 on the right side still clamp and fix the right side of the middle horizontal plate. At this time, under the action of the two sets of second auxiliary mechanisms 3, the upper and lower pressure members 307 on the left side respectively fit against the upper and lower surfaces of the middle horizontal plate facing the left side and move horizontally left and right in this area. The first grinding plate 410 and the second grinding plate 413 extend out and also move back and forth in this area, thereby realizing the full grinding of the upper and lower surfaces of the middle horizontal plate facing the left side. Similarly, the upper and lower surfaces of the middle horizontal plate facing the right side can also be fully ground, thus realizing the full grinding of the bent workpiece without dead angles. S4. After grinding, the four sets of pressure pieces 307 are kept parallel to the two ear plates under the action of the two sets of second auxiliary mechanisms 3. With the action of the processing mechanism 4, the drilling head 406 drills holes at the required positions of the ear plates. During drilling, the two sets of abutment plates 414 in the processing mechanism 4 below fit against the bottom of the ear plate below the drilling position, which plays a supporting role and prevents the ear plate from being tilted and suspended, which would cause the drilling position to deviate. This improves the drilling quality. After drilling, the tapping head 407 is used to tap the threads inside the drilled hole to form the ear plate mounting hole. The state of the workpiece at this time is called intermediate body B-1. S5. The robotic arm 101 takes the intermediate body B-1 out of the box 102 and transfers it to the top of the support plate 502 in the welding mechanism 5. It controls the output end of the sixth electric push rod 503 to extend, which drives the pressure plate 504 to move downward and clamp and fix the horizontal plate of the intermediate body B-1. S6. We then use the robotic arm 101 to clamp another set of workpieces on the external conveyor and transfer them into the housing 102. Under the action of the first auxiliary mechanism 2, the two sets of second clamping members 209 on the right side clamp the workpiece. It is worth noting that the long side of the workpiece is parallel to the left and right sides inside the housing 102. Under the action of the output end of the first electric push rod 105 and the two output ends of the first dual-axis electric push rod 106, the two sets of first clamping members 107 move synchronously to the left and clamp and fix the middle right side of the workpiece. Then, under the action of the second auxiliary mechanism 3 and the processing mechanism 4, the cutting head 409 makes a longitudinal cut on the part of the two sets of first clamping members 107 that is clamped to the left, thereby forming a strip-shaped reinforcing rib B-2. The front and rear ends of the strip-shaped reinforcing rib B-2 are then modified to form a notch that can fit with the inclined ear plate. S7. Following step S6, two sets of reinforcing ribs B-2 with notches at the front and rear ends are processed and clamped by two sets of third clamping parts 517. Then, the output end of the third servo motor 514 drives the third threaded rod 512 to rotate, causing the two sets of moving plates 515 to move closer or further apart. This, in turn, causes the two sets of reinforcing ribs B-2 in the clamped state to move closer or further apart, changing the spacing between the two sets of reinforcing ribs B-2. This allows for the selection of a suitable spacing between the two sets of reinforcing ribs B-2 for installation based on the width of different intermediate bodies B-1. Furthermore, the output end of the third stepper motor 508 drives the third lead screw 506 to rotate. The moving block 509 reciprocates along the outer wall of the third guide rod 507, thereby moving the two sets of reinforcing ribs B-2 in the clamping state to the bottom of the intermediate body B-1. In conjunction with the extension of the output end of the seventh electric push rod 510, the two sets of reinforcing ribs B-2 move upward and abut against the corresponding installation position. Finally, the welding robot 518 welds the two sets of reinforcing ribs B-2 together with the intermediate body B-1 to form a curtain wall aluminum alloy corner connector. Due to the presence of the reinforcing ribs B-2, the strength is improved to a certain extent, which further improves the service life of the corner connector.
