[0033] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application. However, persons having ordinary skill in the art will readily recognize that the application can be practiced without all the specific details given herein. Therefore, persons having ordinary skill in the art, having the benefit of the present application as taught by the descriptions hereof, can effect numerous modifications as to the items and methods set forth in the preceding description, the implementation of which will be in the best interest of the practice of the application. Therefore, the preceding description in its entirety should not be construed as limiting, but merely providing an illustrative basis for the claims.

[0034] The words of "front", "back", "left", "right" and the like in the present embodiment are for the purpose of clear expression, and are not the definite position and direction. The position relationship of each device and mechanism can be different in other specific embodiments.

[0035] As shown in Figure 1 and Figure 2 , the disc changing and turning equipment 100 comprises a rack 11, and a machine shell 10 is wrapped outside the rack 11 for protecting each internal structure in the machine shell 10. A first stacking assembly 21 and a second stacking assembly 22 are arranged in front of and behind each other to the left side outside the machine shell, and a third stacking assembly 23 and a fourth stacking assembly 24 are arranged in front of and behind each other to the right side outside the machine shell. A first carrier input device 31 extends from the bottom of the first stacking assembly 21 into the machine shell for inputting the first carriers stacked in the first stacking assembly 21 one by one, and a second carrier input device 32 extends from the bottom of the second stacking assembly 22 into the machine shell for inputting the second carriers stacked in the second stacking assembly 22 one by one. A second carrier output device 33 extends from the inside of the machine shell 10 to the third stacking assembly 23 for outputting the second carriers loaded with products outside the machine shell 10 and stacking and collecting in the third stacking assembly 33, and a first carrier output device 34 extends from the inside of the machine shell 10 to the fourth stacking assembly 24 for outputting the empty first carriers outside the machine shell 10 and stacking and collecting in the fourth stacking assembly 24. That is, the first stacking assembly 21 is arranged above the input end of the first carrier input device 31, the second stacking assembly 22 is arranged at the input end of the second carrier input device 32, the third stacking assembly 23 is arranged at the output end of the second carrier output device 33, and the fourth stacking assembly 24 is arranged at the output end of the first carrier output device 34. The conveying directions of each input and output device can be arranged to be the same. The carrier input device and the loading manipulator 51 can be arranged on the mounting plate 12, and the carrier output device and the disc removing manipulator 52 can be arranged on the mounting plate 13.

[0036] Figure 3 The structure of the first stacking assembly 21 and the first carrier input device 31 is shown in Figure 3As shown, the stacking assembly 21 is located above the input end of the first vehicle input device 31. The first vehicle input device 31 includes two conveying tracks 311 and a drive motor 312. The lifting mechanism 313 is located between the two conveying tracks 311 and downstream along the conveying direction of the first vehicle input device 31. An adjustment mechanism 314 for adjusting the track width is also provided. The structures of other vehicle input / output devices can be similar to those of the first vehicle input device.

[0037] Figure 4 The structure of the first lifting mechanism 313 is shown, as follows: Figure 4 As shown, the lifting mechanism 313 includes a lifting plate 3131 and a cylinder 3132. The cylinder 3132 pushes the lifting plate 3131 upward to lift the first carrier on the conveying track 311 until it is disengaged from the conveying track 311 and the first carrier is fixed. After the second carrier covers the first carrier, it drives the lifting plate 3131 downward to release the first carrier, allowing the product assembly to be placed on the conveying track 311 and conveyed along the conveying direction to the flipping device 40. The structure of the second lifting mechanism in the second carrier output device 33 can be the same as or similar to the structure of the first lifting mechanism 313. Similar lifting mechanisms can also be provided in the second carrier input device 32 and the first carrier output device 34. By fixing the carrier through the lifting mechanism, accurate positioning and convenient control can be achieved when placing the second carrier on the first carrier and when removing the first carrier from the product assembly.

[0038] The loading robot 51 is positioned above the first carrier input device 31 and the second carrier input device 32, such as... Figure 5 As shown, the system includes a Y-axis moving module 511, a Z-axis moving module 512, and a suction cup assembly 513 located below the Z-axis moving module. This assembly is used to transfer the second carrier conveyed by the second carrier input device 32 onto the first carrier located on the first carrier input device 31. At this time, a product is placed on the first carrier. The loading robot 51 covers the first carrier and the product with the second carrier, clamping the product between the first and second carriers, forming a product assembly including the first carrier, the product, and the second carrier. The product assembly is conveyed by the first carrier input device 31 to the conveying mechanism of the flipping device 40. After the flipping device 40 flips the product assembly, it is conveyed by the conveying mechanism to the second carrier output device 33.

[0039] The disassembly robot 52 is positioned above the second carrier output device 33 and the first carrier output device 34. It is used to disassemble the product components on the second carrier output device 33 and transfer the first carrier to the first carrier output device 34. Then, the first carrier is output from the housing 10 by the first carrier output device 34 to the fourth stacking assembly 34 for stacking and collection. After the product components are removed from the first carrier, they become the second carrier with the flipped product. The second carrier with the product is output from the housing 10 by the second carrier output device 33 to the third stacking assembly 23 for stacking and collection.

[0040] The first carrier input device 31 and the second carrier output device 33 are located on the same straight line, and the second carrier input device 32 and the first carrier output device 34 are located on the same straight line. The flipping device 40 is located between the first carrier input device 31 and the second carrier output device 33. Its conveying mechanism receives product components from the first carrier input device 31 and conveys the flipped product components to the second carrier output device 33. A first detection camera may be installed above the first carrier input device 31, and a second detection camera may be installed above the second carrier output device 33. The detection cameras can determine the status of the products in the first or second carrier, such as whether there is a shortage of materials, and issue an early warning to facilitate further processing.

[0041] In this embodiment, the input / output devices of each carrier, the manipulator and each stacking component can adopt known structures. The separation mechanism, stacking mechanism and lifting mechanism, etc., can refer to various structures commonly used in the art, which will not be described in detail here. The main innovation of this utility model is the flipping device. The specific structure of the flipping device is described in detail below.

[0042] like Figure 6 As shown, the flipping device 40 includes a support base 41 and a rotating body. The rotating body includes a mounting frame 42 and a conveying mechanism 43, an upper pressing mechanism 44, and a lower pressing mechanism 45 mounted thereon. The conveying mechanism 43 is hollow and includes two oppositely arranged first conveying rails 431 and second conveying rails 432. The flipping drive mechanism 411 is mounted on the support base 41 and drives the mounting frame 42 to rotate, thereby causing the upper pressing mechanism 44, the lower pressing mechanism 45, and the conveying mechanism 43 to rotate synchronously.

[0043] like Figure 7As shown, the mounting frame 42 includes an upper mounting plate 4211 and a lower mounting plate 4212, and a frame formed by lateral mounting plates 4213 and 4214. At the central axis of the frame, the lateral mounting plate 4213 is provided with a mounting joint 22 for connecting to and being driven by the flipping drive mechanism 411. The lateral mounting plate 4214 is provided with an outwardly protruding shaft 23, which is rotatably supported by a support base 41. Two upper mounting guide rails 4261 are provided below the upper mounting plate 4211, and two lower mounting guide rails 4262 are provided above the lower mounting plate 4212 for mounting conveyor rails 431 and 432. The upper mounting plate 4211 is also provided with sliders 4241 and 4242, and a scale 42111 indicating the position of the sliders. The lower mounting plate 4212 is provided with sliders 4251 and 4252 for connecting with the conveyor rails 431 and 432. Each slider is provided with a limit groove, and each mounting plate is provided with a positioning hole 42112. The position of each slider is limited by a positioning pin.

[0044] The connection method between the support base and the mounting frame is not limited to those described above. The flipping drive mechanism can also drive the mounting frame in other ways, as long as it can achieve stable rotation of the mounting frame and the rotation angle can be precisely controlled.

[0045] Figure 8 The first conveying track 431 of the conveying mechanism 43 is shown, and the second conveying track 432 is arranged approximately symmetrically to the first conveying track. Figure 8 As shown, the first conveying track 431 includes a drive unit 4311, drive wheels 4317 and 4318, driven wheels, an upper conveyor belt 4312, a lower conveyor belt 4313, a mounting plate 4314, an upper mounting sleeve 4315, and a lower mounting sleeve 4316. The drive unit 4311 is used to rotate the drive wheels 4317 and 4318 in different directions, thereby driving the lower part of the upper conveyor belt 4312 and the upper part of the lower conveyor belt 4313 to move synchronously, further driving the products conveyed on the conveyor belt to move along the conveying direction. The upper mounting sleeve 4315 is used to be fitted on the mounting guide rail 4261, and the lower mounting sleeve 4316 is fitted on the mounting guide rail 4262. The mounting plate 4314 is also provided with a connecting part for fixed connection with the sliders 2141 and 2151.

[0046] When adjusting the distance between the two conveyor tracks 431 and 432 to accommodate different carriers, first remove the positioning pins installed on the upper mounting plate 4211 and lower mounting plate 4212 of the mounting frame 42. Pull the conveyor track or slider to allow the mounting sleeve of the conveyor track to slide on the mounting guide rails 4261 and 4262. Determine the required track width according to the position indicated on the scale 4211. Then, install the positioning pin in the appropriate positioning hole to fix the slider and the conveyor track. By using two synchronous conveyor belts, product components can be conveyed in the conveying mechanism 43 along the conveying direction before and after flipping. Through the cooperation of the mounting sleeve and the mounting guide rail, the conveyor tracks 431 and 432 can be reliably installed in the mounting frame 42. The slider can be fixed relative to the mounting guide rail by fixing the fixing structure. Opening the fixing structure can adjust the distance between the conveyor tracks to accommodate the conveying of different types of product components.

[0047] like Figure 9 As shown, the upper pressing mechanism 44 includes a driving part 441, a mounting part 442, and an upper pressing part 443. The driving part 441 can be configured as a motor with a screw to drive the upper pressing part 443 to move in a direction perpendicular to the conveying direction and the central axis of the mounting frame 42. The mounting part 442 is used to fix the upper pressing mechanism 44 on the upper mounting plate 4211 of the mounting frame 42. The upper pressing part 443 is provided with a buffer assembly including an elastic buffer 444 and an upper pressing part 445. To make the movement of the upper pressing part 443 smoother, the upper pressing mechanism is also provided with a cooperation structure of multiple guide posts 447 and guide sleeves 448. One end of each guide post 447 is connected to the connecting part 446, and the other end is connected to the upper pressing part 443. The guide sleeves 448 are fixedly connected to the mounting part 442.

[0048] like Figure 10 As shown, the lower pressing mechanism 45 includes a driving part 451, a mounting part 452, and a pressing part 453. The driving part 451 can be configured as a motor with a screw to drive the upper pressing part 453 to move in a direction perpendicular to the conveying direction and the central axis of the mounting frame 42. The mounting part 452 is used to mount the lower pressing mechanism 45 on the lower mounting plate of the mounting frame. The lower pressing part 453 is provided with an elastic material layer 4531, positioning pins 4531 and 4532, and a blocking member 4533. To make the movement of the lower pressing part 453 smoother, the lower pressing mechanism is also provided with a cooperation structure of multiple guide posts 457 and guide sleeves 458. One end of each guide post 4577 is connected to the connecting part 456, and the other end is connected to the lower pressing part 453. The guide sleeve 458 is fixedly connected to the mounting part 452. The pressing part 453 can be provided with a clearance structure for the blocking member 4533. The use of cushioning components and elastic material layers makes the various parts of the product components fit together better, preventing misalignment and reducing the impact on the product components during pressing.

[0049] It is understandable that the driving part of the pressing mechanism can also adopt a structure such as a cylinder, as long as it can realize the smooth movement of the pressing part in a direction perpendicular to the conveying direction and the central axis of the mounting frame.

[0050] In operation, the first carrier containing the product is stacked in the first stacking assembly 21, and the empty second carrier is stacked in the second stacking assembly 22. The tray-separating mechanism of the first stacking assembly 21 places the bottommost first carrier on the first carrier input device 31 and conveys it along the conveying direction. After reaching a specific position, the first lifting mechanism 313 lifts the first carrier until it is detached from the conveying track 311 and fixed. At the same time, the separating mechanism of the second stacking assembly 22 places the bottommost second carrier on the second carrier input device 32 and conveys it along the conveying direction. Then, the loading robot 51 grabs the second carrier and transfers it above the first carrier and the product to form a product assembly. The first lifting mechanism 313 moves down, placing the product assembly on the conveying track 311 and further conveying it to the conveying mechanism 43 of the flipping device 40.

[0051] The conveying mechanism 43 further conveys the product assembly along the conveying direction until the product assembly contacts the blocking member 4533 provided on the lower pressing part 453. Then the conveying of the product assembly stops. The driving part 441 of the upper pressing mechanism 44 drives the upper pressing part 443 to move downward. At the same time, the driving part 451 of the lower pressing mechanism 45 drives the lower pressing part 453 to move upward until the upper pressing part 443 contacts the surface of the second carrier. The elastic material layer 4531 of the lower pressing part 453 contacts the surface of the first carrier and moves further. The positioning pins 4531 and 4532 provided on the lower pressing part 453 are respectively inserted into the positioning holes of the upper pressing part 443. Under the elastic buffer of the buffer component and the elastic material layer 4531, the product assembly is tightly clamped by the upper and lower pressing parts under a certain pressure, and the product in the carrier cannot move relative to the product.

[0052] The flipping drive mechanism 411 drives the rotating body, including the mounting frame 42, upper pressing mechanism 44, lower pressing mechanism 45, and conveying mechanism 43, to rotate 180 degrees. The upper pressing mechanism 44 rotates to the bottom and the lower pressing mechanism 45 rotates to the top. The drive part 441 of the upper pressing mechanism 44 drives the upper pressing part 443 to move downward away from the product component, while the drive part 451 of the lower pressing mechanism 45 drives the lower pressing part 453 to move upward away from the product component, until the upper and lower pressing parts are completely separated from the surface of the product component without affecting the conveying of the product component along the conveying direction. The drive parts 4311 of the first conveying track 431 and the drive parts of the second conveying track 432 rotate in opposite directions to drive the synchronous conveyor belt to convey the flipped product component to the second carrier output device 33 along the conveying direction. After the product component is separated from the conveying mechanism 43, the flipping drive mechanism 411 drives the rotating body to rotate 180 degrees again, so that the upper pressing mechanism 44 returns to the top and the lower pressing mechanism 45 returns to the bottom, so as to perform the next flipping and conveying.

[0053] After the product component is conveyed to the second carrier output device 33 and reaches a specific position, the second lifting mechanism lifts and secures the product component. The disassembly robot 52 disassembles the first carrier on top of the product component and transfers it to the first carrier output device 34. The second lifting mechanism then lowers, placing the second carrier loaded with the flipped product onto the conveying track of the second carrier output device 33, and further conveying it along the conveying direction to below the third stacking assembly 23. The stacking mechanism of the third stacking assembly 23 lifts and secures it, leaving space below to accommodate the next second carrier. The empty first carrier is conveyed by the first carrier output device 34 to below the fourth stacking assembly 24, where the stacking mechanism of the fourth stacking assembly 24 lifts and secures it, leaving space below to accommodate the next first carrier.

[0054] The tray-separating mechanism of the first stacking assembly 21 continues to place the bottommost first carrier onto the first carrier input device 31 and transport it along the conveying direction, while the separating mechanism of the second stacking assembly 22 continues to place the bottommost second carrier onto the second carrier input device 32 and transport it along the conveying direction, for the next work cycle. Since each stacking assembly is located outside the housing, loading and unloading can be performed without stopping the machine when there are too many or too few carriers inside the assembly.

[0055] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art may make modifications without departing from the scope of the invention; all variations or modifications made in accordance with the present invention shall be covered by the protection scope of the present invention.
