Description

Technical Field

[0001] This invention relates to the field of hinge assembly technology, and in particular to a hinge assembly system. Background Technology

[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. Hinges can be composed of movable components or made of foldable materials. A hinge typically includes a first hinge piece, a second hinge piece, a connecting shaft, and a bushing. The first bushing is located on the side edge of the first hinge piece, and the second bushing is located on the side edge of the second hinge piece. The connecting shaft passes through the holes of the first and second bushings in sequence to connect the first and second hinge pieces. For example, document CN113714797A discloses a hinge assembly system where, when hinge one and hinge two are conveyed to the assembly table, the first arc portion and the second arc portion are misaligned and inserted; when hinge one and hinge two are conveyed to the folding table, hinge one and hinge two fold together, a pin pusher can push the pin through the first and second arc portions, and an end cap pusher can push the end cap onto the pin.

[0003] However, the aforementioned patents and common hinge assembly equipment on the market cannot meet the needs of hinge component assembly. This is because hinge assembly equipment occupies a large area, making it difficult to find assembly errors in a short time during the hinge assembly process. In the case of mass production of hinges, this can easily affect the assembly speed of subsequent hinges.

[0004] To address the aforementioned problems, a hinge assembly system is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a hinge assembly system that solves the problem in the prior art that existing hinge assembly equipment has difficulty finding assembly errors in a short time during the hinge assembly process, and the assembly speed of the hinge is easily affected.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hinge assembly system, comprising a circular worktable and an assembly mechanism mounted on the top of the worktable. The top of the worktable is also equipped with a feeding mechanism A, a feeding mechanism B, and a discharging mechanism, which are installed sequentially on the top of the worktable. The worktable includes a frustum and side holes on the outer surface of the frustum. Four sets of side holes are provided, with two sets of side holes respectively housing a placement frame and a bottom inclined frame for hinge discharging. The assembly mechanism is mounted on the upper end of the placement frame. Triangular teeth are installed on the inner wall of the frustum and on one side of the placement frame. A bottom groove is formed through the bottom of the frustum, and a limiting annular groove is formed inside the bottom groove and within the body of the frustum. The placement frame, bottom inclined frame, and feeding mechanism are also present. Both mechanism A and feeding mechanism B are equipped with legs at their bottom ends to support the worktable; they also include a rotating mechanism, which includes a rotating plate with a limiting ring installed on its outer surface. The limiting ring is used to limit the rotation of the rotating plate within the limiting ring groove. The top of the rotating plate has an inverted T-shaped groove, and there are four sets of inverted T-shaped grooves. An assembly table for placing hinges is installed inside the inverted T-shaped groove. The assembly table includes a rotating plate with external teeth installed on its outer surface. The external teeth mesh with the triangular teeth and drive the rotating plate to rotate. An inverted T-shaped turntable is installed at the bottom end of the rotating plate. The inverted T-shaped turntable is used to limit the rotation of the rotating plate within the inverted T-shaped groove. A torsion spring is installed at the bottom end of the inverted T-shaped groove, and the top end of the torsion spring is installed at the bottom end of the inverted T-shaped turntable for rotating the rotating plate.

[0007] Furthermore, an alignment frame for hinge alignment is installed at the top of the rotating plate, and a turning groove is provided through the middle of the alignment frame.

[0008] Furthermore, an installation strip is installed at the bottom of the frustum, a motor is installed at the bottom of the installation strip, a coupling is installed at the output end of the motor, and the top of the coupling is installed at the bottom of the rotating plate. The operation of the motor drives the rotating plate to rotate inside the bottom groove, and the limiting ring rotates inside the limiting ring groove.

[0009] Furthermore, the assembly mechanism includes a top frame, a frame groove is provided on one side of the outer surface of the top frame, the frame groove is aligned with the placement frame, a connecting frame is installed on one side of the outer surface of the top frame, a bottom frame is installed at the bottom end of the connecting frame, and the interior of the connecting frame is connected to the interior of the bottom frame.

[0010] Furthermore, an L-shaped push plate A is slidably installed on one side of the bottom frame, and a cylinder A is installed on one side of the bottom frame and below the L-shaped push plate A. The moving end of the cylinder A is used to push the L-shaped push plate A to move inside the bottom frame.

[0011] Furthermore, the feeding mechanism A includes a feeding frame A installed on one side of one of the other two sets of side holes. A discharge pipe A is installed on one side of the top of the feeding frame A. A hinge slot A is opened through the middle of the discharge pipe A. The hinge slot A communicates with the interior of the feeding frame A.

[0012] Furthermore, an L-shaped push plate B is slidably installed on one side of the feed frame A, and a cylinder B is installed on one side of the feed frame A and below the L-shaped push plate B. The moving end of the cylinder B is used to push the L-shaped push plate B to move inside the feed frame A.

[0013] Furthermore, the feeding mechanism B includes a feeding frame B installed on one side of one of the other two sets of side holes. A discharge pipe B is installed on one side of the top of the feeding frame B. A hinge slot B is opened through the middle end of the discharge pipe B, and the hinge slot B communicates with the interior of the feeding frame B.

[0014] Furthermore, an L-shaped push plate C is slidably installed on one side of the feed frame B, and a cylinder C is installed on one side of the feed frame B and below the L-shaped push plate C. The moving end of the cylinder C is used to push the L-shaped push plate C to move inside the feed frame B.

[0015] Furthermore, the unloading mechanism includes an unloading frame installed at the top of the frustum. The top of the unloading frame is provided with a push groove. Limiting grooves are provided on both sides of the inner wall of the push groove. Limiting sliders are slidably installed inside the push groove and the limiting grooves.

The moving end of the pushing cylinder is installed on one side of the limiting slider and is used to pull the limiting slider.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The hinge assembly system provided by the present invention involves the first hinge piece inside the hinge slot A falling into the inside of the feed frame A. After the rotating plate stops rotating, the alignment frame containing the first hinge piece faces the feed frame B, and the second hinge piece inside the hinge slot B falls into the inside of the feed frame B. The first and second hinge pieces are aligned and inserted. The motor continues to operate, and at this time, the rotating plate containing the first and second hinge pieces contacts the triangular teeth. Because the outer surface of the rotating plate is equipped with external teeth, the rotating plate and the external teeth are restricted by the triangular teeth and rotate when the rotating plate rotates. The opening direction of the rotating slot faces the side hole, and the connecting shaft is inserted into the connecting hole of the first and second hinge pieces, thus placing them in a position. The internal bushing machine drives the bushing to rotate, and the bushing is threaded onto the connecting shaft to assemble the first and second hinge pieces. After assembly, the hinge moves with the rotation of the rotating plate. During the rotation of the rotating plate, the torsion spring uses its own restoring force to drive the rotating plate to rotate back. When the rotating plate stops rotating, the opening of the alignment frame with the hinge faces the bottom inclined frame, pushing the cylinder to retract. The limit slider moves inside the push groove and the limit groove. The bottom tip push plate pushes the hinge out from inside the alignment frame. The hinge is unloaded from inside the bottom inclined frame, completing the assembly of the hinge. This equipment occupies a small area, and the top of the truncated cone is exposed, allowing the operator to find errors in the hinge assembly in a short time. Attached Figure Description

The moving end of the cylinder C75 is used to push the L-shaped push plate C74 inside the feed frame B71 to move the L-shaped push plate C74. The movement of the L-shaped push plate C74 will push the second hinge piece into the interior of the alignment frame 35, and the first hinge piece and the second hinge piece will be inserted into each other.

[0035] The unloading mechanism 8 includes an unloading rack 81 installed at the top of the frustum 11. The top of the unloading rack 81 is provided with a push groove 82. Limiting grooves 83 are provided on both sides of the inner wall of the push groove 82. Limiting sliders 85 are slidably installed inside the push groove 82 and the limiting grooves 83. A telescopic cylinder 86 is installed at the top of the limiting slider 85. The moving end of the telescopic cylinder 86 passes through the limiting slider 85.

The moving end of the pushing cylinder 84 is installed on one side of the limiting slider 85 and is used to pull the limiting slider 85.

[0036] Specifically, the opening of the alignment frame 35 at the top of the rotating plate 31 faces the feed frame A61. The first hinge piece inside the hinge slot A63 falls into the feed frame A61. The extension of the cylinder B65 pushes the L-shaped push plate B64 to move inside the feed frame A61. The top of the L-shaped push plate B64 blocks the bottom of the hinge slot A63. The movement of the L-shaped push plate B64 pushes the first hinge piece into the alignment frame 35. The operation of the motor 19 drives the rotating plate 21 and the limiting ring 22 to rotate inside the bottom groove 16 and the limiting ring groove 17, respectively. During the rotation of the rotating plate 21, the cylinder B65 retracts, the L-shaped push plate B64 returns to its original position, and the first hinge piece inside the hinge slot A63 falls into the feed frame A61. After the rotating plate 21 stops rotating, the alignment frame 35, which contains the first hinge piece, faces the feed frame B71. The second hinge piece inside the hinge piece slot B73 falls into the feed frame B71. The cylinder C75 extends and pushes the L-shaped push plate C74 to move. The moving L-shaped push plate C74 pushes the second hinge piece into the alignment frame 35. The first and second hinge pieces are aligned and inserted. After unloading, the alignment frame 35 will be realigned with the feed frame A61. During the process of the second hinge piece entering the alignment frame 35, the first hinge piece is pushed by the L-shaped push plate B64 and moves into the alignment frame 35 after unloading. The motor 19 continues to operate. At this time, the rotating plate 31, which contains the first and second hinge pieces, contacts the triangular tooth 15. Due to the outer surface of the rotating plate 31... The rotating plate 21 is equipped with external teeth 32, so that when the rotating plate 21 rotates, the rotating plate 31 and the external teeth 32 are restricted by the triangular teeth 15 and rotate. The alignment frame 35 with the first hinge piece moves to one side of the feed frame B71. The inverted T-shaped turntable 33 rotates inside the inverted T-shaped rotating groove 23. The torsion spring 34 is deformed by the torsion force. At this time, the opening position of the alignment frame 35 rotates 90°, and the opening direction of the rotating groove 36 faces the side hole 12. The connecting shaft inside the connecting frame 53 falls into the bottom connecting frame 54. The cylinder A56 extends, and the L-shaped push plate A55 moves inside the bottom connecting frame 54 under the thrust of the cylinder A56. The connecting shaft is inserted into the connecting hole of the first hinge piece and the second hinge piece. The bushing machine inside the placement frame 13 will drive the bushing to rotate. The hinge is assembled by a bushing threaded onto a connecting shaft, assembling the first and second hinge pieces. After assembly, the hinge moves with the rotation of the rotating plate 21. During rotation, the torsion spring 34 uses its restoring force to drive the rotating plate 31 to rotate back. When the rotating plate 21 stops rotating, the opening of the alignment frame 35 containing the hinge faces the bottom inclined frame 14. At this time, the telescopic cylinder 86 extends, the bottom tip push plate 87 moves down and inserts into the alignment frame 35, pushing the cylinder 84 to retract. The limiting slider 85 moves within the push groove 82 and the limiting slot 83, and the bottom tip push plate 87 pushes the hinge out of the alignment frame 35. The hinge is then unloaded from the bottom inclined frame 14, completing the hinge assembly. This equipment occupies a small area.Furthermore, the top of the frustum 11 is exposed, allowing the operator to quickly locate errors in the hinge assembly.
