Description

Technical Field

[0001] The invention relates to the technical field of hinge assembly, in particular to an intelligent robot used for automatic hinge assembly. Background Art

[0002] Hinge is also known as hinge, and its official name is hinge. It is usually composed of two folds, and is a part that connects two parts of an object and enables them to move. Ordinary hinges are used for cabinet doors, windows, etc.; the materials include iron, copper and stainless steel.

[0003] Hinge is generally composed of the following accessories: 1. Hinge leaf; 2. Hinge core; 3. Knurled pin (beautiful, hinge core anti-falling function). The assembly process of hinge is: insert the hinge core into the two hinge leafs that have been spliced, and then insert the two knurled pins into the two ends of the spliced ​​hinge. The hinge core is the main accessory of the hinge. Through this accessory, the two hinge leaves can be connected in series, and the knurled pin can be used to block the two ends of the hinge to prevent the hinge core from falling off. During the production and assembly process of the hinge, different assembly equipment is needed to assist in the assembly of the hinge core and the knurled pin to improve the assembly efficiency of the hinge.

[0004] The existing hinge assembly equipment gradually exposed its shortcomings during use, mainly in the following aspects:

[0005] First, the continuity of hinge assembly processing is poor. Specifically, two different sets of auxiliary assembly equipment are required for auxiliary assembly when installing the hinge core and the knurled pin. When assembling the hinge, first place the two hinge leaves that have been spliced ​​in the hinge core auxiliary assembly equipment, insert the hinge core into the hinge leaf through the hinge core auxiliary assembly equipment, and then transfer the hinge leaf with the hinge core inserted into the knurled pin auxiliary assembly equipment, and insert the knurled pin into both ends of the hinge leaf through the knurled pin auxiliary assembly equipment to complete the assembly of the hinge. During the entire assembly process of the hinge, it is necessary to frequently fix and disassemble between different auxiliary assembly equipment. Therefore, the continuity of hinge assembly processing is poor.

[0006] Second, the two hinge leaves need to be manually spliced ​​before the hinge is assembled. To ensure that the hinge core can be normally inserted into the hinge leaves, the two hinge leaves require high precision when splicing. Therefore, the splicing process of the hinge leaves is complicated, and manual loading and unloading are required during the assembly of the hinge through the hinge core auxiliary assembly equipment and the knurled pin shaft auxiliary assembly equipment. Therefore, the degree of automation of the equipment is low and the workload of the operating workers is heavy.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When splicing two hinged leaves, the direction adjustment motor drives the rotating box to rotate to a vertical state, and the two hinged leaves to be spliced ​​are placed on the top of the two sliding blocks respectively. The telescopic cylinder drives the driving plate to slide, and then drives the moving clamp plate to move in the direction close to the fixed clamp plate until the fixed clamp plate and the moving clamp plate completely clamp and fix the hinge leaves. The two positioning telescopic cylinders on the same fixed U-shaped plate drive the two positioning plates to move toward each other synchronously until the two positioning plates are against the hinged leaves. At this time, the two hinged leaves are respectively located in the center of the two fixed U-shaped plates. The direction adjustment motor drives the two rotating boxes to rotate to a horizontal state. At this time, the two hinged leaves are both in a horizontal state. The pneumatic telescopic cylinder drives the two fixed U-shaped plates to move toward each other until the two hinges are The ends of the hinge pieces facing each other are inserted, and the upper electrically controlled telescopic cylinder drives the moving plate and the insertion rod to move horizontally until the insertion rod penetrates the two inserted hinge pieces, and the driving telescopic cylinder drives the driving plate and the moving clamping plate to reset, and the telescopic end of the positioning telescopic cylinder contracts appropriately, and the positioning plate is separated from the hinge piece, and the sliding block is reset under the action of the compression spring, and the pneumatic telescopic cylinder drives the two fixed U-shaped plates to move back to each other until they are reset, and the hinge piece rotates downward under the action of its own gravity until the two hinge pieces are against each other, thereby completing the splicing of the two hinge pieces, and after the two hinge pieces are spliced, the positioning telescopic cylinder drives the positioning plate to reset, and the direction adjustment motor drives the rotating box to rotate to a vertical state, realizing the function of automatic splicing of the two hinge pieces, and the splicing speed is fast and the splicing accuracy is high;

[0029] 2. After the two hinged pages are spliced, the lower electric control telescopic cylinder drives the lifting plate to move downward to the preset position. Under the drive of the lifting plate, the lower insertion rod and the two hinged pages move downward. With the cooperation of the inclined structure on the top of the clamping box, the two hinged pages are inserted into the clamping box. The clamping telescopic cylinder drives the clamping block to move in the direction close to the hinged pages until the two clamping blocks abut against the two hinged pages and then clamp and fix the two hinged pages, realizing the function of automatic feeding of the two hinged pages after splicing;

[0030] 3. When installing the hinge core and the knurled pin on the hinge leaves in the clamping box, the stepper motor drives the single-thread screw to rotate, and then drives the two drive blocks to move toward the hinge core material box until the drive block moves to the preset position. The servo motor drives the drive shaft and the two fixed circular plates to rotate, and one of the hinge cores in the hinge core material box enters the material storage grooves on the same horizontal line of the two fixed circular plates. During the rotation of the fixed circular plates, the hinge core in the material storage groove falls into the receiving box, and the telescopic cylinder is controlled to drive the transition block and the push rod to move horizontally. When the push rod is against the hinge core in the receiving box, the hinge core is pushed until the hinge core passes through the circular groove and is inserted into the two hinge leaves in the clamping box. At this point, the hinge core is completed. Automatic installation, the lower driving motor drives the rotating shaft and the clamping box to rotate 90°, the lower hydraulic telescopic cylinder drives the two driven vertical plates to slide toward each other until the two V-shaped plates correspond to the two ends of the hinge leaves, the control motor drives the rotating column to rotate, the knurled pin in the knurled pin hopper enters the transfer groove, during the rotation of the rotating column, the knurled pin in the transfer groove falls into the V-shaped plate through the blanking groove, the upper hydraulic telescopic cylinder drives the fixed plate and the sliding rod to slide horizontally, and pushes the knurled pins in the two V-shaped plates into the two ends of the hinge leaves respectively, thus completing the installation of the knurled pin. The equipment has good continuity in hinge assembly processing, and realizes the function of fast and automatic assembly of hinges without disassembling and transferring hinge leaves;

[0031] 4. After the hinge is assembled, the stepper motor drives the driving block to slide an appropriate distance in the opposite direction, the upper driving motor drives the rotating block to rotate 90°, the clamping telescopic cylinder drives the clamping block to reset, and then releases the restriction on the hinge. The ejecting telescopic cylinder drives the ejecting plate to move in the direction close to the clamping box, and the ejecting plate passes through the ejecting slot into the clamping box and pushes the hinge until the hinge is ejected out of the clamping box and falls into the collection box for collection, thus realizing the function of automatic unloading and collection of the assembled hinge. Therefore, the equipment has a high degree of automation, which can not only automatically splice the two hinge leaves with fast splicing speed and high splicing accuracy, but also automatically load the two spliced ​​hinge leaves and automatically unload and collect the assembled hinge, greatly reducing the workload of the staff.
