[0050] Combination Figures 3 to 11 As shown, an automatic assembly device for copper nuts includes an injection molding machine 1, a belt conveyor 2, a three-axis robot 3, a clamping assembly 4, a third mounting plate 5, a vibratory feeder 6, a feeding mechanism 7, a discharge assembly 8, and an air pipe 9.

[0051] The injection molding machine 1 is equipped with an injection mold 11 for injection molding products. The model of the injection molding machine 1 is MA6000II.

[0052] Belt conveyor 2 is located on one side of injection molding machine 1 and is used for automatic transport of products to the corresponding process.

[0053] The three-axis robot 3 is installed on the injection molding machine 1 and is used to transfer products to the belt conveyor 2. Under the action of the three-axis robot 3, the products can be moved simultaneously along the three axes of X, Y and Z to transfer the corresponding products to the belt conveyor 2.

[0054] The bottom of the three-axis robot 3 is equipped with a clamping component 4 for clamping and picking up products. Under the action of the clamping component 4, the product can be clamped and picked up, and the corresponding product is clamped to the belt conveyor 2 for unloading. The clamping component 4 includes a first mounting plate 41, and a rotary cylinder 42 is fixedly installed at the bottom of the first mounting plate 41. The output end of the rotary cylinder 42 is connected to a second mounting plate 43, and multiple clamping parts 44 are arranged on the second mounting plate 43 along its height direction.

[0055] In this process, the rotary cylinder 42 drives the second mounting plate 43 to rotate, and the second mounting plate 43 drives the clamping member 44 to rotate together. At the same time, the three-axis robot 3 drives the corresponding clamping member 44 to move along the X, Y and Z axes to the injection mold 11 until the clamping member 44 clamps the corresponding product. The rotary cylinder 42 drives the second mounting plate 43 to rotate, and the second mounting plate 43 drives the clamping member 44 to rotate together. At the same time, the three-axis robot 3 drives the corresponding clamping member 44 to move along the X, Y and Z axes to the belt conveyor 2. The corresponding clamping member 44 releases the corresponding product to place the product on the belt conveyor 2, and the belt conveyor 2 transports the product to the corresponding process.

[0056] A vibratory plate 6 is installed on the belt conveyor 2 via the third mounting plate 5 for filling nuts.

[0057] The discharge end of the vibratory feeder 6 is connected to a material distribution component 61, which is used to automatically distribute the nuts, so that the nuts can be automatically distributed under the action of the material distribution component 61.

[0058] A feeding mechanism 7 is provided on one side of the material distribution component 61. The feeding mechanism 7 is located on the upper surface of the third mounting plate 5 and is used to transport nuts. The feeding mechanism 7 includes an air blowing component 71. The air inlet of the air blowing component 71 is connected to an external pressure air pipe. A mounting base 72 is provided on one side of the air blowing component 71. A feeding component 73 is slidably mounted on the mounting base 72. The inlet of the feeding component 73 is connected to the outlet of the air blowing component 71. A telescopic cylinder 74 is provided on one side of the mounting base 72. The output end of the telescopic cylinder 74 is connected to the feeding component 73 and is used to drive the feeding component 73 to directly below the air blowing component 71. The second mounting plate 43 The device is equipped with a discharge component 8, which is located below the clamping member 44. The discharge component 8 is connected to the feeding component 73 via an air pipe 9, and is used to inject the nuts in the air pipe 9 into the corresponding nut holes on the product. Through the combined action of the distributing component 61, the feeding mechanism 7, the discharge component 8, and the air pipe 9, the nuts are automatically distributed to the feeding component 73. The feeding component 73 automatically conveys the nuts into the air pipe 9 and then into the discharge component 8, thus delivering the corresponding nuts to the corresponding nut holes on the product, achieving… To achieve automatic conveying, the air blowing assembly 71 pressurizes the external pressure air pipe into the feeding assembly 73 and the air pipe 9. Utilizing atmospheric pressure, the pressurized gas generates sufficient impact force to inject the corresponding nut from the air pipe 9 into the corresponding nut hole on the product. This achieves automatic assembly of the nuts, avoiding leaks that can occur during manual assembly. It also reduces the workload of operators and improves the efficiency of nut assembly. Assembly efficiency is improved by providing a telescopic cylinder 74 on one side of the mounting base 72. Under the action of the telescopic cylinder 74, the feeding assembly 73 can be automatically slid below the distributing assembly 61. At this point, the lower part of the distributing assembly 61 and the upper part of the feeding assembly 73 are on the same horizontal plane and overlap. The distributing assembly 61 can automatically distribute nuts into the feeding assembly 73. When the telescopic cylinder 74 drives the feeding assembly 73 to slide below the air blowing assembly 71, the lower part of the air blowing assembly 71 and the upper part of the feeding assembly 73 are aligned. Located on the same horizontal plane and overlapping, the system can automatically transport nuts and automatically assemble them into the corresponding nut holes on the product. Through the combined action of the rotary cylinder 42 and the three-axis robot 3, the second mounting plate 43 is driven to rotate, and the second mounting plate 43 drives the discharge assembly 8 to rotate together. At the same time, the three-axis robot 3 drives the discharge assembly 8 to move along the X, Y and Z axes until the discharge assembly 8 is inserted into the injection mold 11 and corresponds to the corresponding nut hole on the product.

[0059] In this process, the vibratory feeder 6 delivers the corresponding nuts to the feeding assembly 61. The telescopic cylinder 74 drives the feeding assembly 73 to slide below the feeding assembly 61, with the lower part of the feeding assembly 61 and the upper part of the feeding assembly 73 on the same horizontal plane and overlapping. The corresponding nuts enter the feeding assembly 73 from the feeding assembly 61 and then enter the air pipe 9 from the feeding assembly 73. The telescopic cylinder 74 drives the feeding assembly 73 to slide below the blowing assembly 71, with the lower part of the blowing assembly 71 and the upper part of the feeding assembly 73 on the same horizontal plane and overlapping. The external pressure air pipe pressurizes the feeding assembly 73 and the air pipe 9 through the blowing assembly 71. At the same time, the rotary cylinder 42 drives the second mounting plate 43 to rotate, which in turn drives the discharging assembly 8 to rotate. The three-axis manipulator 3 drives the discharging assembly 8 to move simultaneously along the X, Y, and Z axes until the discharging assembly 8 is fully discharged. Inserted into the injection mold 11 and aligned with the corresponding nut hole on the product, the high-pressure gas, using atmospheric pressure, generates enough impact force to inject the corresponding nut from the air pipe 9 into the corresponding nut hole on the product, thus achieving automatic assembly of the corresponding product nut. Next, the three-axis robot 3 drives the discharge assembly 8 to move simultaneously along the X, Y, and Z axes to the outside of the injection mold 11. The rotary cylinder 42 drives the second mounting plate 43 to rotate, and the second mounting plate 43 drives the clamping component 44 to rotate together. Simultaneously, the three-axis... The robotic arm 3 moves the corresponding clamping component 44 along the X, Y, and Z axes to the injection mold 11 until the clamping component 44 clamps the corresponding product. Then, the rotary cylinder 42 drives the second mounting plate 43 to rotate, and the second mounting plate 43 drives the clamping component 44 to rotate together. At the same time, the three-axis robotic arm 3 moves the corresponding clamping component 44 along the X, Y, and Z axes to the belt conveyor 2. The corresponding clamping component 44 releases the corresponding product to place the product on the belt conveyor 2, and the belt conveyor 2 transports the product to the corresponding process.

[0060] In some embodiments, the trachea 9 is configured as three tubes.

[0061] Combination Figure 3 , Figure 7 , Figure 10 and Figure 11As shown, the material distribution assembly 61 includes a material distribution nozzle 611, which has a hollow structure. The inlet end of the material distribution nozzle 611 is connected to the outlet end of the vibrating plate 6. A first fixing plate 612 is fixedly installed on both sides of the material distribution nozzle 611. A second fixing plate 614 is installed on the first fixing plate 612 through the cylindrical frame 613. A plurality of first telescopic cylinders 615 are installed on the second fixing plate 614 along its height direction. The output end of the first telescopic cylinder 615 passes through the second fixing plate 614 and extends into the inner cavity of the material distribution nozzle 611 to restrict the nuts. Under the action of the first telescopic cylinder 615, the nuts can be restricted from entering the feeding assembly 73. Since the air pipe 9 is set to three, it is ensured that only three nuts enter the air pipe 9 each time.

[0062] In some embodiments, two first telescopic cylinders 615 are provided.

[0063] In this process, under the action of the vibrating plate 6, the nuts sequentially enter the distributing nozzle 611 from the discharge end of the vibrating plate 6. When the first nut falls above the first telescopic cylinder 615, the first telescopic cylinder 615 retracts, while the second telescopic cylinder 615 is blocked. When the first nut falls above the second telescopic cylinder 615, the first telescopic cylinder 615 is blocked, until the second nut falls above the first telescopic cylinder 615, at which point the second telescopic cylinder 615 is retracted, until the first nut enters the feeding assembly 73 from the outlet end of the distributing nozzle 611 and sequentially enters the air pipe 9. Only three nuts are allowed to enter the air pipe 9 at a time, and the cycle is based on three nuts.

[0064] Combination Figure 3 , Figure 7 and Figure 8 As shown, the feeding assembly 73 includes a first slide plate 731. A fourth mounting plate 732 is fixedly installed on the upper part of the first slide plate 731. A plurality of funnels 733 are arranged on the fourth mounting plate 732 along its length. The outlet end of the funnel 733 is connected to the discharge assembly 8 through an air pipe 9, so that under the action of the funnel 733, the corresponding nut can enter the air pipe 9 from the funnel 733.

[0065] In some embodiments, since there are three air tubes 9, the number of funnels 733 should be consistent with the number of air tubes 9 to ensure that each cycle can be completed with three nuts. Therefore, there are also three funnels 733.

[0066] In this process, the vibratory feeder 6 delivers the corresponding nuts to the feeding assembly 61. The telescopic cylinder 74 drives the first sliding plate 731 to slide along the mounting base 72. The first sliding plate 731 drives the fourth mounting plate 732 and the funnels 733 to slide together until the upper part of each funnel 733 is on the same horizontal plane and overlaps with the lower part of the feeding nozzle 611. The corresponding nuts enter the funnels 733 from the feeding nozzle 611 and then enter the air pipe 9 from the funnels 733. This continues until all three nuts have entered the air pipe 9 from the three corresponding funnels 733. Then, the telescopic cylinder 74 drives the first sliding plate 731 to slide along the mounting base 72 again. The first sliding plate 731 drives the fourth mounting plate 732 and the funnels 733 to slide together to below the air blowing assembly 71. The lower part of the air blowing assembly 71 and the upper part of the feeding assembly 73 are on the same horizontal plane and overlap, ensuring that the air blowing assembly 71 and the funnels 733 are aligned. The airtight seal between the tubes allows the external pressure tube to pressurize the air inside the tube 9 from the funnel 733 via the air blowing assembly 71.

[0067] Combination Figure 3 , Figure 5 and Figure 6 As shown, the ejector assembly 8 includes a fifth mounting plate 81, on which multiple ejector blocks 82 are provided. Each ejector block 82 has an ejector hole 83. The inlet end of the ejector hole 83 is connected to the outlet end of the air pipe 9, and the outlet end of the ejector hole 83 passes through the fifth mounting plate 81 and extends to the outside of the fifth mounting plate 81. This allows the fifth mounting plate 81 to be inserted into the injection mold 11, aligning the ejector hole 83 with the corresponding nut hole on the product.

[0068] In some embodiments, the number of discharge blocks 82 and discharge holes 83 are the same as the number of air pipes 9, which are set to three.

[0069] After the corresponding nut enters the corresponding air pipe 9, the rotary cylinder 42 drives the second mounting plate 43 to rotate, and the second mounting plate 43 drives the fifth mounting plate 81 to rotate together. The three-axis robot 3 drives the fifth mounting plate 81 to move simultaneously along the X, Y and Z axes until the fifth mounting plate 81 is inserted into the injection mold 11 and the discharge hole 83 is aligned with the corresponding nut hole on the product.

[0070] Combination Figure 3 , Figure 7 and Figure 9As shown, the air blowing assembly 71 includes a sixth mounting plate 711, on which a second telescopic cylinder 712 is provided. The output end of the second telescopic cylinder 712 is connected to a second sliding plate 713. The second sliding plate 713 is slidably mounted on the sixth mounting plate 711. The second sliding plate 713 is provided with a plurality of air blowing pipes 714 along its length. The air inlet end of the air blowing pipe 714 is connected to an external pressure air pipe. The outlet end of the air blowing pipe 714 passes through the second sliding plate 713 and extends to the outside of the second sliding plate 713. Under the action of the second telescopic cylinder 712 and the second sliding plate 713, the air blowing pipe 714 and the funnel 733 can be sealed to ensure the smooth flow of the nut.

[0071] In some embodiments, the air tubes 714 are configured as three.

[0072] When the telescopic cylinder 74 drives the first slide plate 731 to slide along the direction of the mounting base 72, the first slide plate 731 drives the fourth mounting plate 732 and the funnel 733 to slide together. The second telescopic cylinder 712 drives the second slide plate 713 to slide down onto the sixth mounting plate 711 until the upper surface of each funnel 733 is on the same horizontal plane and coincides with the air outlet of each air pipe 714.

[0073] Combination Figure 7 and Figure 8 As shown, a limiting block 75 is fixedly provided on one side of the mounting base 72. Multiple rubber blocks 76 are provided on one side of the upper part of the limiting block 75 along its width direction, so that the sliding of the first slide plate 731 can be restricted under the action of the limiting block 75, preventing the first slide plate 731 from sliding off the mounting base 72, and preventing the first slide plate 731 from colliding with the limiting block 75 under the action of the rubber blocks 76.

[0074] To further explain, clamping component 44 is an electric gripper.

[0075] Combination Figure 3 As shown, the three-axis robot 3 is mounted on the injection molding machine 1 via a mounting base 12.

[0076] The working principle of this invention is as follows:

[0077] The vibratory feeder 6 delivers the corresponding nuts to the dispensing assembly 61. The telescopic cylinder 74 drives the first sliding plate 731 to slide along the mounting base 72. The first sliding plate 731 drives the fourth mounting plate 732 and the funnel 733 to slide together until the upper part of the first funnel 733 and the lower part of the dispensing nozzle 611 are on the same horizontal plane and overlap. Nuts enter the dispensing nozzle 611 from the discharge end of the vibratory feeder 6 in sequence. When the first nut falls above the first telescopic cylinder 615, the first telescopic cylinder 615 retracts, while the second telescopic cylinder 615 is blocked. When the first nut falls above the second telescopic cylinder 615, the first telescopic cylinder 615 is blocked, until the second nut falls above the first telescopic cylinder 615, and the second... The first telescopic cylinder 615 is in a retracted state until the first nut enters the funnel 733 from the outlet end of the dispensing nozzle 611 and then into the air pipe 9. This process is repeated until all three air pipes 9 are fitted with a nut. Only three nuts are allowed to enter the air pipes 9 at a time, with the cycle starting with three nuts. The telescopic cylinder 74 drives the first sliding plate 731 to slide along the mounting base 72. The first sliding plate 731 drives the fourth mounting plate 732 and the funnel 733 to slide together. The second telescopic cylinder 712 drives the second sliding plate 713. The funnel 733 slides downwards onto the sixth mounting plate 711 until the upper surface of each funnel 733 is level with and coincides with the air outlet of each air pipe 714. The funnel 733 and air pipe 714 are sealed by the downward sliding of the second sliding plate 713 driven by the second telescopic cylinder 712. Simultaneously, after the corresponding nut enters the corresponding air pipe 9, the rotary cylinder 42 drives the second mounting plate 43 to rotate. The second mounting plate 43 then rotates the fifth mounting plate 81 together, and the three-axis manipulator 3 drives the fifth mounting plate... Simultaneously, 81 moves along the X, Y, and Z axes until the fifth mounting plate 81 is inserted into the injection mold 11, and the discharge hole 83 is aligned with the corresponding nut hole on the product. Next, the external pressure air pipe pressurizes the air in the air pipe 9 through the air blowing pipe 714 and the funnel 733. Using the pressure of atmospheric pressure, the pressurized high-pressure gas has a certain impact force, which can just inject the corresponding nut in the air pipe 9 into the corresponding nut hole on the product along the trajectory of its discharge hole 83, realizing the automatic assembly of the corresponding product nut. After the corresponding nut is injected into the product;The three-axis robot 3 moves the second mounting plate 43, which in turn moves the fifth mounting plate 81 along the X, Y, and Z axes until the fifth mounting plate 81 gradually moves away from the injection mold 11. Simultaneously, the rotary cylinder 42 drives the second mounting plate 43 to rotate, causing the clamping component 44 to rotate as well. The three-axis robot 3 then moves the second mounting plate 43 and the clamping component 44 along the X, Y, and Z axes until the corresponding clamping component 44 clamps the corresponding product. At the same time, the rotary cylinder 42 drives the second mounting plate 43 to rotate, causing the clamping component 44 to rotate as well. Simultaneously, the three-axis robot 3 moves the corresponding clamping component 44 along the X, Y, and Z axes to the belt conveyor 2. The corresponding clamping component 44 releases the corresponding product and places it on the belt conveyor 2, which then transports the product to the appropriate processing step.
