[0030] See also Figure 1-Figure 11 The automatic unloading and fitting device 100 provided in the embodiment of the present invention comprises a press automatic orderly unloading structure 1 and a fitting connection operation structure 2, wherein the press automatic orderly unloading structure 1 transports the material to the fitting connection operation structure 2.

[0031] The automatic orderly unloading structure 1 of the press comprises an inclined material tray 11, on which a guide bar 12 is arranged, the guide bar 12 forms a unloading port 13, and a discharge port 14 is formed at the bottom of the material tray 11. A rotating disc 15 is arranged between the unloading port 13 and the discharge port 14, and the rotating disc 15 blocks the unloading port 13 and the discharge port 14, and the material slides into the unloading port 13 by its own gravity. The rotating disc 15 is rotatable, and a plurality of grooves 16 are provided on the outer circumference of the rotating disc 15. The material enters the grooves 16 from the unloading port 13, and is brought to the discharge port 14 by the rotation of the rotating disc 15. When the slot width of the groove 16 is less than the width of the discharge port 14, when the edge of the groove 16 rotates into the discharge port 14, the material is transferred to the next station, and when the slot width of the groove 16 is equal to the width of the discharge port 14, when the edge of the groove 16 is aligned with the edge of the receiving port, the material is transferred to the next station. The press automatic orderly unloading structure 1 also includes a vibration assembly 17, which includes a first arm 18, a second arm 19 and a tension spring 111. The connection between the first arm 18 and the second arm 19 is rotatably arranged on the material tray 11, the first arm 18 extends into the groove 16, a fixing seat 112 is arranged between the second arm 19 and the guide bar 12, and the tension spring 111 connects the second arm 19 and the fixing seat 112. When the rotating disc 15 rotates, the groove 16 moves the second arm 19, driving the first arm 18 to hit the guide bar 12, and the material is prompted to enter the groove 16 through vibration.

[0032] The guide bar 12 includes a first guide bar 113 and a first guide bar 114, one end of the first guide bar 113 is located at the material discharge port 13 and is spaced from the rotating disc 15, and the other end is attached to the side wall of the material tray 11, the first guide bar 114 connects the material discharge port 13 and the material discharge port 14 and is in an arc shape corresponding to the outer circumference of the rotating disc 15, and the first guide bar 114 is spaced from the rotating disc 15. The first guide bar 113 and the first guide bar 114 can guide the flow direction of the material and prevent the material from leaking out of the material tray 11.

[0033] In this embodiment, the grooves 16 are provided and evenly opened on the outer circumference of the rotating disc 15, and cooperate with the rotating disc 15 to rotate at a uniform speed to transport the materials to the next station in an orderly manner.

[0034] A striking head 115 is provided at the end of the first arm 18, and the striking head 115 is cylindrical. The smooth outer peripheral surface of the cylindrical striking head 115 can reduce the damage of the first guide strip 113 and extend the service life of the first guide strip 113; a toggle head 116 is provided at the end of the second arm 19, and the toggle head 116 is cylindrical, which facilitates the toggle head 116 to be detached from the groove 16.

[0035] In summary, when the automatic orderly material discharge structure 1 for a press provided by the present invention is implemented, the material moves to the discharge port 13 on the inclined material tray 11 by its own gravity, the rotating disc 15 rotates at a constant speed, the groove 16 moves the second arm 19, drives the first arm 18 to hit the guide bar 12, and the material is prompted to enter the groove 16 from the discharge port 13 through vibration, and the material is automatically and orderly brought to the discharge port 14 through the rotation of the rotating disc 15. The automatic orderly material discharge structure 1 for a press provided by the present invention is simple in structure, easy to use, and can transport the material to the next station in an orderly manner.

[0036] The interlocking connection operation structure 2 includes two primary clamping jaws 21 , a turntable 24 , an image recognition sensor camera 28 , a rotating mechanism 29 and an interlocking mechanism 223 .

[0037] There are several ejector pins 25 evenly distributed on the turntable 24, and a roller guide shaft 26 is connected to the bottom of each ejector pin 25. The roller guide shaft 26 passes through the turntable 24 and is driven up and down by the lifting cylinder, which drives the ejector pins 25 up and down. Furthermore, the turntable 24 stops after rotating a preset angle so that the ejector pins 25 receive the material, and repeats the intermittent movement of rotating and stopping to complete a process of receiving and transferring the material.

[0038] A spring 27 is also wound around the roller guide shaft 26, so that after the roller guide shaft 26 is driven by the lifting cylinder to lift the ejector pin 25, the elastic force of the spring 27 returns to the height before lifting, thereby playing a reset role, reducing loss, and also protecting the roller guide shaft 26.

[0039] Two first-level clamps 21 are arranged above the turntable 24. Furthermore, the two first-level clamps 21 are located directly above the evenly distributed top pins 25. The two first-level clamps 21 also include two groups of first-level left and right clamps 22 and a fixed block 23. The two groups of first-level left and right clamps 22 are driven to rotate and clamp by a rotary cylinder. The design of the two groups of clamps can be suitable for grabbing materials of different sizes. The fixed block 23 is detachably installed in the middle of the two groups of first-level left and right clamps 22, and can be used to hold materials for easy grabbing.

[0040] At the same time, two image recognition sensor cameras 28 are respectively provided for identifying the front and back of the material grasped by the first-level clamp 21. The first clamp places the first material with the front side facing upward on the top pin 25 to form a lower layer of material, and the second clamp places the second material with the front side facing downward on the first material to form an upper layer of material. The two image recognition sensor cameras 28 also need to identify the angle of the upper material that needs to be rotated so that the grooves and protrusions of the two materials are aligned to facilitate subsequent pressing and fitting.

[0041] The rotating mechanism 29 includes a secondary clamp 211, a rotating shaft 212 and a vertically arranged slide rail 220, wherein the secondary clamp 211 is driven by a telescopic cylinder to move forward and backward, a slider 221 is slidably arranged on the slide rail 220, and the slider 221 is rotatably connected to the rotating shaft 212 via a U-shaped nut 222. At the same time, the rotating shaft 212 is connected to a second synchronous pulley 218, and the second synchronous pulley 218 is connected to a first synchronous pulley 217 driven to rotate by a rotating motor via a synchronous toothed belt 219. The head of the rotating shaft 212 is also provided with a first slot 213 matching the ejector pin 25, and two layers of rubber pressing sheets 214 are provided. During the rotation operation, the secondary clamp 211 grasps the lower material on the top pin 25, and the rotating shaft 212 moves downward to make the top pin 25 extend into the first slot 213. At this time, the head of the rotating shaft 212 is close to the upper material and starts to rotate. The rubber pressing sheet 214 drives the upper material to rotate through friction, so that the grooves and protrusions of the two materials are aligned.

[0042] At the same time, a displacement sensor 215 and a micro joint 216 are also provided in the rotating mechanism 29 , which are used to detect whether the upper material is rotated into place and receive the signal sent by the displacement sensor 215 .

[0043] The interlocking mechanism 223 includes a pressing plate 224 driven by a lifting cylinder. The head of the pressing plate 224 is also provided with a second slot 225 matching the ejector pin 25. After the two aligned materials are rotated into the interlocking mechanism 223, the pressing plate 224 moves downward so that the ejector pin 25 extends into the second slot 225, and the head of the pressing plate 224 is in close contact with the upper material. The pressing plate 224 continues to move downward to press the two materials together.

[0044] At the same time, a three-stage clamp 226 is also provided under the pressing plate 224. When the interlocking and clamping operation is performed, the three-stage clamp 226 is driven by the telescopic cylinder to extend forward into the roller guide shaft 26 under the clamping turntable 24 to prevent the pressing plate 224 from causing damage to the turntable 24 due to excessive force, thereby playing a supporting and anti-fixing role.

[0045] The working principle of the present invention is: after the material is unloaded by the unloading mechanism, it is transferred to the fixed block 23 of the two primary clamps 21, and the rotating motor drives the left and right primary clamps 22 to grab the material. The image recognition sensor camera 28 above is used to identify the front and back of the material. The front side of the first material with grooves and protrusions faces upward, and the front side of the second material faces downward, and it is flipped or not flipped accordingly. Subsequently, when the turntable 24 rotates and drives the ejector pin 25 to rotate to the bottom of the first primary clamp 21, the turntable 24 stops rotating, and the roller guide shaft 26 moves upward to lift the ejector pin 25 so that the first material is sleeved on the ejector pin 25 to form a lower layer of material. The roller guide shaft 26 moves downward again and is reset by the elastic force of the spring 27. At the same time, the left and right jaws 22 of the first level release the material so that the material follows the ejector pin 25 to fall. The turntable 24 continues to rotate, and when the ejector pin 25 rotates to the bottom of the second primary clamp 21, it stops rotating. The roller guide shaft 26 moves upward again to lift the ejector pin 25 so that the second material is sleeved on the ejector pin 25 to form an upper layer of material. At this time, the upper layer of material is in contact with the front of the lower layer of material, and the image recognition sensor camera 28 recognizes the angle at which the upper layer of material needs to be rotated, and sends a signal to the rotating mechanism 29.

[0046] The turntable 24 continues to rotate, and the top pin 25 stops rotating when it rotates to the front of the secondary clamp 211. The secondary clamp 211 is driven by the telescopic motor to extend forward and grasp the lower material. The rotating shaft 212 is driven by the slider 221 to move downward. The first slot 213 opened at the head of the rotating shaft 212 is tightly sleeved with the top pin 25, and the two layers of rubber pressing sheets 214 at the head of the rotating shaft 212 are fitted with the reverse side of the upper material. The rotating motor drives the synchronous pulley to rotate and drives the rotating shaft 212 to rotate. The rubber pressing sheet 214 drives the upper material to rotate through friction, so that the grooves and protrusions on the front of the upper and lower materials are aligned. The displacement sensor 215 is used to detect whether the material is rotated into place, and the micro connector 216 is used to receive the signal sent by the displacement sensor 215.

[0047] After the rotation operation is completed, the turntable 24 continues to rotate, and the top pin 25 stops rotating when it rotates to the bottom of the pressing plate 224. At this time, the three-stage clamp 226 is driven by the telescopic motor to extend forward to grasp the roller guide shaft 26 under the grabbing plate, and the pressing plate 224 is driven by the lifting motor to move downward, so that the second slot hole 225 opened at the head of the pressing plate 224 is tightly fitted with the top pin 25, and continues to move downward to press and fit the upper material and the lower material together. At the same time, the three-stage clamp 226 grasps the roller guide shaft 26 to prevent the turntable 24 from being damaged due to excessive force of the pressing plate 224.

[0048] The structure of the present invention is simple and reasonable. The rotating top pin 25 drives the material to rotate, and the whole process of unloading, discharging, rotating and engaging is completed respectively. The two sets of first-level clamps 21 can grab materials of different sizes. The detachable fixed block 23 can also be used to hold materials of different sizes. The spring 27 on the roller guide shaft 26 can reduce the loss and protect the turntable 24 at the same time. The displacement sensor 215 and the micro joint 216 are used to detect whether the rotation is in place, which improves the operation accuracy. The material is driven to rotate by two layers of rubber pressing sheets 214, which also improves the operation accuracy. Finally, a three-level claw clamp is used to clamp the roller guide shaft 26 to prevent the pressing plate 224 from damaging the turntable 24 due to excessive force during the engaging operation. Finally, the whole process is fully automatic, which reduces labor costs and improves production efficiency.

[0049] In summary, in the embodiment of the present invention, the press automatic orderly unloading structure 1 unloads materials fully automatically, the interlocking connection operating structure 2 assembles fully automatically, and the press automatic orderly unloading structure 1 automatically transports materials to the interlocking connection operating structure 2 to achieve efficient assembly.
