Description

Technical Field

[0001] The invention relates to an angle bracket assembly mechanism, in particular to an angle bracket assembly mechanism for a profile frame. Background Art

[0002] The solar aluminum frame is the supporting outer frame of the photovoltaic solar panel. The frame is connected with angle codes. The angle codes have dense teeth and are connected very firmly through the punching and riveting process. The process of pressing the angle codes on both ends of the existing aluminum profile frame is mainly performed manually. It is necessary to hold the aluminum profile frame manually and then use the pressing equipment to place and press the angle codes one by one. The corner code pressing process of the entire solar module frame requires manual participation. Manual operation has low work efficiency and poor processing quality, which increases labor costs. During the entire processing process, the production and processing accuracy of the solar module frame is poor, which easily causes the aluminum profile to twist and skew. The existing production and processing automation level of the solar module frame is low and cannot meet the needs of production and use.

[0003] Therefore, there is an urgent need for a profile frame corner code assembly mechanism with a higher degree of automation and better structural stability, thereby ensuring a lower probability of error in the assembly process. Summary of the invention

[0018] 2. After the first clamping part moves to the top of the material storage group, the first longitudinal cylinder can drive the angle code matching claw to descend. When the distance sensor at the bottom can detect the set distance position, the clamping soft block can clamp the angle code and rise under the drive of the piston. The angle code is taken out and then slid horizontally to the top of the horizontal conveyor under the drive of the lateral sliding drive component. When the material is discharged, the angle code will flip toward one end of the pushing part when it falls, until one side of the angle code is placed on the conveying belt of the horizontal conveyor. After the conveying belt drives the angle code to move for a period of time, the electric clamping claw of the second clamping part clamps the other side of the angle code and rises to move toward the top of the pushing part. After it is in place, it descends and places the angle code on the placement table. When the angle code is pushed toward the two end holes of the profile, the profile can be pressed and positioned by the top clamping cylinder.

[0019] 3. The angle code loading section is combined with an automatically operated profile loading section, a horizontal transfer carrier for automatically transferring the loaded profile to the next work station, and a pushing section for automatically assembling the transferred angle code and profile, thereby achieving better stability, lower error rate, and better automation, thereby greatly improving production efficiency.

The corner bracket loading portion 2 is symmetrically distributed on both sides of the support frame 1, and includes at least one material storage group 21, a transverse sliding frame 22, a longitudinal sliding frame 23, and a horizontal conveyor 24. The transverse sliding frame 22 is slidably connected to a first clamping portion 25 that can slide laterally, and the longitudinal sliding frame 23 is slidably connected to a first clamping portion 25 that can slide longitudinally.

[0028] The material holding group 21 includes two groups of inclined blocks 211, vertical poles 212 and limiting side poles 213. The two groups of inclined blocks 211 are arranged opposite to each other and are used to cooperate and support on the outside of the angle code 6. The vertical poles 212 are fixed on both sides of the inclined blocks 211 and are used to be limited at both ends of the opening of the angle code 6. The limiting side poles 213 are fixed and limited on both sides of the opening of the angle code 6.

[0029] It also includes an auxiliary correction part 7, which includes a correction support platform 71 placed between the pushing part 4 and the profile feeding part 3, and an end cylinder 72 installed on the correction support platform 71 for correcting the two ends of the profile, which can assist in correcting the position of the two ends of the profile groove before feeding to the pushing part 4, thereby improving the accuracy of the assembly of the angle code 6.

[0030] The horizontal moving carrier 5 is installed on the movable end of the sliding drive cylinder, and the third clamping part includes a vertical drive cylinder 51 fixed under the horizontal moving carrier 5, a frame 52 fixed at the end of the vertical drive cylinder 51, and three groups of pneumatic clamping jaws 53 equidistantly distributed side by side under the frame 52 for clamping the profiles placed sequentially on the profile feeding part 3, the correction support platform 71, and the pushing part 4.

[0031] The first clamping part 25 includes a first longitudinal cylinder 251 and an angle code matching claw 252 installed at the movable end of the first longitudinal cylinder 251. The angle code matching claw 252 includes a matching block 2521 matched inside the angle code 6, a distance sensor 2522 embedded in the bottom of the matching block 2521, and a clamping soft block 2523 embedded in the inclined surfaces on both sides of the matching block 2521. The matching block 2521 is also provided with two groups of intersecting and connected piston cavities 2524, and a piston is provided in the piston cavity 2524. One end of the piston is connected to the clamping soft block 2523 through a connecting rod 2525. The matching block 2521 is also provided with an air inlet 2526 and an air outlet 2527 which can be connected to the piston cavity 2524. The top end of the first longitudinal cylinder 251 is installed on the transverse sliding frame 22, and the bottom end is provided with a groove connected to the short rod of the angle code matching claw 252 through a spring 2528. This not only improves the feeding stability, but also the elastic connection setting can reduce the possible bump damage caused by offset errors.

[0032] The movable part of the lateral fixing cylinder 43 is limited on both sides of the profile and the angle code 6 by the lateral fixing plate 431. The two ends of the lateral fixing plate 431 are also fixed with a pulley shaft 432, and the pulley shaft 432 is rotatably connected with a pulley. The two sets of pulleys are connected to a transmission belt 433 that can be sleeved on the outside of the lateral fixing plate 431. Therefore, after the lateral fixing cylinder 43 is positioned on both sides of the profile and the angle code 6, it can return to its original position. At this time, the pushing part 4 pushes the angle code 6 toward the profile socket, and it can also not return. In the original position, when pushing the angle code 6, in order to avoid the friction between the two sides of the angle code 6 and the lateral fixed plate 431, a transmission belt 433 can be arranged between the angle code 6 and the lateral fixed plate 431. The inner side of the transmission belt 433 rubs against the lateral fixed plate 431, while the outer side can move synchronously with the angle code 6 without generating friction. The synchronous movement can be generated by the static friction generated by clamping the angle code 6, or by the driving force of the driving component driving the pulley and rotating the transmission belt 433.

[0033] The material holding group 21 is distributed in a ring shape and is fixed on a rotating table. The rotating table can be an electric rotating table.

[0034] Fixed side plates are provided on both sides of the horizontal conveyor 24 .

[0035] The second clamping portion 26 includes a second longitudinal cylinder 261 and an electric clamping jaw 262 mounted on a movable end of the second longitudinal cylinder 261 .

[0036] A limiting inclined plate 241 is also provided at one end of the horizontal conveyor 24 away from the pushing part 4. The limiting inclined plate is fixed above the horizontal conveyor 24 through a fixing frame and is used to limit the side of the first clamping part 25 where the angle code 6 is tilted.

[0037] The working principle of the present invention is: through the cooperation of the transverse sliding frame 22, the longitudinal sliding frame 23, and the horizontal conveyor 24, the automatic loading of the angle code 6 is realized, not only the overall loading stability is better, the probability of wrong loading is smaller, but also the degree of automation is higher, which is more time-saving and labor-saving; after the first clamping part 25 moves to the top of the material storage group 21, the first longitudinal cylinder 251 can drive the angle code matching claw 252 to descend, and when the distance sensor 2522 at its bottom can detect the set distance position, the clamping soft block 2523 can clamp the angle code 6 and rise under the drive of the piston, take out the angle code 6, and then slide horizontally to the top of the horizontal conveyor 24 under the drive of the transverse sliding driving component, and when releasing the material, the angle code 6 will turn toward the direction of one end of the pushing part 4 when it falls. Rotate until one side of the angle code 6 is placed on the conveyor belt of the horizontal conveyor 24. After the conveyor belt drives the angle code 6 to move for a period of time, the electric clamp 262 of the second clamping part 26 clamps the other side of the angle code 6, rises and moves toward the top of the pushing part 4, and after it is in place, it descends and places the angle code 6 on the placing table 41. When the angle code 6 is pushed toward the two end holes of the profile, the profile can be pressed and positioned by the top clamping cylinder; the angle code loading part 2 is combined with the profile loading part 3 which can be automatically operated, the horizontal transfer carrier 5 for automatically transferring the loaded profile to the next work station, and the pushing part 4 for automatically assembling the transferred angle code 6 and the profile, so as to achieve better stability, lower error rate and better degree of automation, thereby greatly improving the production efficiency.
