Product conveying device

Abstract

The utility model discloses an embodiment of a product conveying device, which drives the overturning of the overturning platform through the overturning part and drives the up-and-down movement of the lifting platform through the first lifting part. When the lifting platform drives the product to move upwards to approach the overturning platform, the fixing part can fix the product to avoid the product from falling during overturning. Thus, on the one hand, during the overturning of the product, the relative sliding of the product and the overturning mechanism is avoided, and the first face and the second face of the product are prevented from being scratched. On the other hand, when the product pickup part places the product on the lifting platform, the lifting platform and the overturning platform are staggered by the movement of the moving part, so that the interference between the pickup module and the overturning mechanism is avoided. At the same time, the product pickup part can approach or move away from the lifting platform and the overturning platform along the vertical direction, further avoiding the product from being scratched.

[0101] The present invention will now be described based on embodiments, but it is not limited to these embodiments. In the following detailed description of the present invention, certain specific details are described in detail. Those skilled in the art will fully understand the present invention even without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0102] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0103] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0104] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0105] Unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0107] Figure 1 This is a schematic diagram of the product conveying device in this embodiment. Figure 2 This is an exploded view of the product conveying device in this embodiment. Figure 3 This is a schematic diagram of the conveying direction of the product conveying device in this embodiment.

[0108] In some implementations, such as Figures 1-2 As shown, the product conveying device in this embodiment includes a mounting base plate 3 and a flipping mechanism 1, a conveying mechanism 2, a first feeding module 4, a second feeding module 7, a second conveying component 8, and a vision positioning unit 9 disposed on the mounting base plate 3.

[0109] Further reference Figure 3 As shown in the figure, the material conveying direction of the product conveying device is illustrated. Thick dashed lines represent the approximate conveying path of product A, while thin dashed lines represent the conveying paths of the first material package 51 on the first feeding module 4, the second material package 52 on the second feeding module 7, and the second carrier plate 521 on the second conveying assembly 8. The handling mechanism 2 can be a four-axis robotic arm, and dashed lines indicate the movement area of ​​the picking module 21.

Figure 6 This is a schematic diagram of the structure of product A and the first carrier disk 512 in this embodiment. Figure 7 This is a schematic diagram of the structure of Product A and the second carrier disk 521 in this embodiment. Figure 8 This is a schematic diagram of the structure of the first material package 51 in this embodiment. The multiple first carrier trays 512 in the middle position are not shown in the figure. The upper first carrier tray 512 is in a loaded state, and the lower first carrier tray 512 is in an unloaded state. Figure 9This is a schematic diagram of the structure of the second material pack 52 in this embodiment. The structure of the second material pack 52 is similar to that of the first material pack 51, except that the second material pack 52 is provided with a second carrier tray 521.

[0111] In some implementations, such as Figure 4 As shown, the pickup module 21 in this embodiment includes a product pickup section 211 and a tray pickup section 212. The product pickup section 211 is provided with a plurality of first suction heads for adsorbing product A, and the tray pickup section 212 is provided with two grippers for gripping the second tray 521. The pickup module 21 also includes a vision sensor disposed between the product pickup section 211 and the tray pickup section 212, which can identify product A, the first tray 512, and the location of the first tray 512.

[0112] Further reference Figure 5 As shown, product A can be a circuit board motherboard. It includes a board frame A4 and multiple component units A3 disposed on the board frame A4, each component unit A3 being an independent circuit board. A half-groove A5 is formed on the board frame A4 to facilitate cutting in the next process, and the edge of the board frame A4 is provided with a first positioning hole A1 for positioning product A. Product A includes a first surface A21 and a second surface A22. In the first feeding module 4, the first surface A21 is placed facing upwards. After being flipped by the flipping mechanism 1, in the second conveying assembly 8, the second surface A22 is placed facing upwards.

[0113] Figure 10 , Figure 11 and Figure 12 This is a schematic diagram of the working state of the flipping mechanism 1 in this embodiment. Figure 11 Product A was not shown in the image.

[0114] In some implementations, such as Figures 10-12 As shown, the flipping mechanism 1 includes a first lifting part 11, a flipping part 12, and a moving part 13. One of the first lifting part 11 or the flipping part 12 is disposed on the moving part 13, so that the moving part 13 can drive the first lifting part 11 to move or drive the flipping part 12 to move. The first lifting part 11 includes a lifting platform 111, and the flipping part 12 includes a flipping platform 121. The flipping platform 121 is provided with a fixing part 1211. The first lifting part 11 can drive the lifting platform 111 to move up and down, and the flipping part 12 can drive the flipping platform 121 to flip. During this process, the fixing part 1211 can fix product A and prevent product A from falling.

[0115] The conveying mechanism 2 is configured such that when the moving part 13 drives the lifting platform 111 and the tilting platform 121 to be horizontally offset from each other (e.g.) Figure 10As shown by the two dashed lines I in the diagram, product A is placed on the lifting platform 111 via the product pickup unit 211, with the first surface A21 of product A facing upwards. This avoids interference between the product pickup unit 211 and the flipping unit 12. A first positioning pin 524 for positioning product A can be provided on the lifting platform 111.

[0116] The flipping mechanism 1 is configured such that the moving part 13 drives the lifting platform 111 and the flipping platform 121 to a relative position with the flipping platform 121 facing the lifting platform 111. In this configuration, the lifting platform 111 moves upward and closer to the flipping platform 121, causing product A on the lifting platform 111 to gradually approach the flipping platform 121. The flipping platform 121 fixes product A to the fixing part 1211, and then the flipping platform 121 flips away from the lifting platform 111 to face the second surface A22 upward. In this configuration, the product picking part 211 picks up product A to complete the flipping operation of product A.

[0117] Optionally, the flipping platform 121 flips upward in a first direction and downward in a second direction, the first direction being opposite to the second direction. The flipping angle of the flipping platform 121 is 180 degrees, ensuring that product A remains horizontal before and after the flip, facilitating pickup by the product picking unit 211. Before the flipping platform 121 flips upward, the first lifting unit 11 drives the lifting platform 111 downward to avoid collision between the flipping platform 121 and the lifting platform 111. When the moving unit 13 drives the flipping unit 121 to move away from or towards the first lifting unit 11, the flipping platform 121 flips downward to prevent collision between the lifting platform 111 and the flipping platform 121, thus accelerating the movement speed of the flipping mechanism 1.

[0118] In summary, the product conveying device in this embodiment drives the flipping platform 121 to flip via the flipping part 12, and drives the lifting platform 111 to move up and down via the first lifting part 11. When the lifting platform 111 moves product A upward to approach the flipping platform 121, the fixing part 1211 can fix product A to prevent product A from falling during flipping. Thus, on the one hand, during the flipping process of product A, relative sliding between product A and the flipping mechanism 1 is prevented, and scratches on the first surface A21 and the second surface A22 of product A are prevented. On the other hand, when the product picking part 211 places product A on the lifting platform 111, the moving part 13 drives the lifting platform 111 and the flipping platform 121 to be staggered, preventing interference between the picking module 21 and the flipping mechanism 1. At the same time, this allows the product picking part 211 to approach or move away from the lifting platform 111 and the flipping platform 121 in the vertical direction, further preventing product A from being scratched.

[0119] In some implementations, such as Figures 10-11As shown, the fixing part 1211 includes a plurality of first suction heads, which together form a first group of suction heads 1212 and a second group of suction heads 1213. Along the length of the flipping platform 121, the first group of suction heads 1212 and the second group of suction heads 1213 are located at opposite ends of the flipping platform 121 and extend away from the flipping platform 121. Furthermore, along the width of the flipping platform 121, the plurality of first suction heads in the first group of suction heads 1212 and the second group of suction heads 1213 are arranged sequentially. In this embodiment, the first suction heads are used to adsorb product A, preventing the fixing part 1211 from scratching product A.

[0120] Further reference Figure 5 and Figure 12 As shown, in this embodiment, the first set of suction heads 1212 and the second set of suction heads 1213 are used to actuate the two edges of the plate frame A4 respectively, so as to avoid the fixing part 1211 from contacting the component unit A3 and ensure the cleanliness of the second surface A22 of the component unit A3.

[0121] In some implementations, such as Figure 10 As shown, the flipping unit 12 also includes a first transmission unit 122, a first spacer 123, and a first driver 124. The first spacer 123 includes a first upper plate 1231 and two support arms 1232. The first upper plate 1231 is spaced above the moving part 13. The two support arms 1232 extend to the same side of the first upper plate 1231, and the opposite sides of the two support arms 1232 form a clearance space 1233. The flipping platform 121 is located in the clearance space 1233 and is rotatably connected to the two support arms 1232. The first driver 124 is disposed on the first upper plate 1231 and drives the flipping platform 121 to flip through the first transmission unit 122.

[0122] Specifically, the first driver 124 can be a motor, and the first transmission part 122 can be a transmission belt and pulley. After the support arm 1232 extends horizontally to one side of the first upper plate 1231, it bends upwards on the first upper plate 1231 to increase the height of the tilting platform 121 and avoid interference between the tilting platform 121 and the tilting part 12 below.

[0123] Furthermore, such as Figure 1 As shown, the product conveying device also includes a mounting base plate 3. A first lifting part 11 is disposed on the mounting base plate 3, and a tilting part 12 is disposed on the mounting base plate 3 via a moving part 13. Further referencing... Figure 10 As shown, the moving part 13 drives the flipping part 12 to move towards the side of the first upper plate 1231 away from the support arm 1232, so as to avoid the product picking part 211. Therefore, in this embodiment, the flipping part 12 is arranged such that the moving part 13 and the flipping platform 121 are aligned, ensuring the horizontal movement accuracy of the flipping platform 121, so that the lifting platform 111 and the flipping platform 121 can be aligned.

[0124] Specifically, the first spacer 123 also includes two upright plates and a first lower plate located below the first upper plate 1231. The two upright plates are positioned between the first upper plate 1231 and the first lower plate, thereby raising the height of the first upper plate 1231. The first lower plate is connected to a drive slider. The drive slider is mounted on a ball nut, which is fitted onto a ball screw. A rotating motor drives the first spacer 123 to reciprocate through the ball nut.

[0125] Figure 13 This is a schematic diagram of the structure of the first feeding module 4 in this embodiment. Figure 14 and Figure 15 This is an exploded view of the first feeding module 4 in this embodiment.

[0126] In some implementations, such as Figure 1 As shown, the product conveying device also includes a first feeding module 4. Further referencing... Figure 13 As shown, the first feeding module 4 includes a pick-and-place section 41, a first conveying assembly 42, and multiple first material bags 51. Further referencing... Figure 14 As shown, the first conveying component 42 has a pickup area 421. Multiple first material packages 51 are disposed on the first conveying component 42 and are conveyed through the first conveying component 42. Further referring to… Figure 8 As shown, the first material package 51 includes a material box 511 and a plurality of first trays 512 for carrying product A, with the plurality of first trays 512 disposed in the material box 511.

[0127] The first feeding module 4 is configured as a pick-and-place unit 41 to take out the first tray 512 from the material box 511 and move it to the pickup area 421 (e.g., ...). Figure 8 , Figure 13 Arrow a1 and Figure 14 As shown), the product pickup unit 211 picks up product A (e.g., product A) from the pickup area 421. Figure 1 As shown), the product pickup unit 211 moves product A to the lifting platform 111, and the pick-and-place unit 41 returns the first tray 512 (as shown). Figure 8 (As indicated by arrow a2 in the diagram). Thus, the first carrier tray 512 inside the first material bag 51 is removed and put back to facilitate the recovery of the empty first material bag 51.

[0128] In some implementations, such as Figure 3 and Figure 15 As indicated by arrow a3, the first conveying assembly 42 includes a tray conveying line 61 and a bin conveying line 62. The tray conveying line 61 is used to convey the first tray 512, and the bin conveying line 62 is used to convey the bin 511 containing the first tray 512.

[0129] Further reference Figure 14As shown, the tray conveyor line 61 has the aforementioned pick-up area 421. Further referencing... Figure 15 As shown, the material box conveyor line 62 includes, in sequence, an inlet 621, a lifting area 623, and an outlet 622 in the conveying direction. The second lifting unit 63 includes a lifting slide rail 631, which moves up and down between the lifting area 623 and the tray conveyor line 61. The lifting slide rail 631 lifts the material box 511 to the tray conveyor line 61 (e.g., ...). Figure 13 As shown), the pick-and-place section 41 takes out product A from the material box 511.

[0130] Specifically, the lifting slide rail 631 extends in the same direction as the tray conveyor line 61, and the lifting slide rail 631 is raised to the same height as the tray conveyor line 61. Limiting claws are also provided on the side of the lifting slide rail 631 to prevent the first material bag 51 from moving. The lifting slide rail 631 moves the material box 511 to the lifting area 623, and the material box conveyor line 62 drives the first material bag 51 of the lifting slide rail 631 to move towards the discharge port 622.

[0131] Specifically, the lifting slide rail 631 moves to the bottom of the material box conveyor line 62, so that the material box 511 falls on the material box conveyor line 62, so that the material box conveyor line 62 can convey the empty material box 511 to the discharge port 622.

[0132] In some implementations, such as Figures 14-15 As shown, the material conveyor line 62 includes two first conveyor belts 624 arranged in pairs, two second conveyor belts 625 arranged in pairs, an intermediate slide rail 626, a third lifting section 628, and a material feeding section 627. One end of each of the two second conveyor belts 625 forms a discharge port 622, and the opposite side of the other end forms a lifting area 623. The material feeding section 627 includes a push plate 6271. One end of each of the two first conveyor belts 624 forms a feed port 621, and the other end is adjacent to one end of the intermediate slide rail 626. The other end of the intermediate slide rail 626 is adjacent to the lifting area 623. The push plate 6271 pushes the first material bag 51 from the first lifting platform 6281 through the intermediate slide rail 626 to the lifting slide rail 621.

[0133] Specifically, the lifting slide rail 631 has three lifting positions in the height direction. In the first lifting position, the height of the lifting slide rail 631 is basically the same as the height of the tray conveyor line 61, and the lifting slide rail 631 moves within a certain height range. In the second lifting position, the height of the lifting slide rail 631 is the same as the height of the intermediate slide rail 626, and the height of the lifting slide rail 631 is slightly higher than the top of the first conveyor belt 624 and the second conveyor belt 625 to prevent the material box 511 from contacting the first conveyor belt 624 and the second conveyor belt 625. In the third lifting position, the lifting slide rail 631 is located below the bottom of the first conveyor belt 624 and the second conveyor belt 625, so that the two sides of the bottom of the material box 511 are supported by the second conveyor belt 625 to facilitate the conveying by the second conveyor belt 625.

[0134] In some implementations, such as Figures 14-15 As shown, the first conveyor belt 624 and the second conveyor belt 625 are arranged side by side. Further referencing... Figure 16 As shown, the first feeding module 4 also includes a second spacer 43, which includes a second upper plate 431. The second upper plate 431 is spaced above the first conveyor belt 624, a tray conveyor line 61, and a pick-and-place section 41. The material feeding section 627 is located at one end of the two first conveyor belts 624 away from the feed inlet 621 and below the second spacer 43.

[0135] Specifically, the bottom of the second upper plate 431 is also provided with multiple support legs, which are mounted on the mounting base plate 3 to raise the tray conveyor line 61 and the pick-and-place section 41. This makes the structure of the first feeding module 4 more compact.

[0136] In some implementations, such as Figures 14-15 As shown, the material box conveyor line 62 also includes a plurality of third lifting units 628. The third lifting units 628 are disposed between two first conveyor belts 624 or two second conveyor belts 625, and the plurality of third lifting units 628 are arranged at intervals along the conveying direction of the material box conveyor line 62. Each third lifting unit 628 includes a first lifting platform 6281. The third lifting unit 628 is configured to move the first lifting platform 6281 upward to lift the first material bag 51 above the first conveyor belt 624 or the second conveyor belt 625. The third lifting unit 628 is also configured to move the first lifting platform 6281 downward to allow the first material bag 51 to fall onto the first conveyor belt 624 or the second conveyor belt 625.

[0137] Specifically, when the first lifting platform 6281 lifts the first material bag 51 above the first conveyor belt 624 or the second conveyor belt 625, the height of the first lifting platform 6281 is the aforementioned second lifting position. Simultaneously, a third lifting part 628 is correspondingly arranged with the intermediate slide rail 626. When the first lifting platform 6281 of the third lifting part 628, the lifting slide rail 631, and the intermediate slide rail 626 are simultaneously at the same height, the push plate 6271 can push the first material bag 51 from the first lifting platform 6281 to the intermediate slide rail 626, and then from the intermediate slide rail 626 to the lifting slide rail 631 (e.g., ...). Figure 15 (As shown).

[0138] Optionally, in the conveying direction of the material box 511, a baffle is provided on the front side of each first lifting platform 6281, so that the baffle abuts against the front side of the bottom of the material box 511, so that the material box 511 falls stably into the first lifting platform 6281.

[0139] Figure 16 This is a schematic diagram of the structure of the second spacer 43 and the tray conveyor line 61 in this embodiment.

[0140] In some implementations, such as Figure 16 As shown, the tray conveyor line 61 includes two first slide rails 611, with the opposite sides of the two first slide rails 611 forming the aforementioned pick-up area 421. A plurality of first trays 512 are arranged at intervals in the hopper 511. The pick-up / placement section 41 includes a clamping structure 411 located between the two first slide rails 611 and includes two clamps 4111 and a pusher block 4112. The two clamps 4111 clamp the upper and lower edges of the first trays 512 and pull the first trays 512 to the pick-up area 421. In this configuration, the product pick-up section 211 picks up product A. Then, the pusher block 4112 pushes the empty first tray 512 against the hopper 511.

[0141] Specifically, in this embodiment, the material bin 511 has a storage compartment, and the side wall of the storage compartment is provided with multiple pairs of protruding ridges. The first tray 512 can be placed on two of the protruding ridges, so that multiple first trays 512 are spaced apart. The second lifting part 63 can cooperate with the pick-and-place part 41 to lift. The second lifting part 63 is configured such that when the push block 4112 pushes the empty first tray 512 to the material bin 511 and is pulled back, the lifting slide rail 631 descends a predetermined distance, so that the first tray 512 above the empty first tray 512 corresponds to the tray conveyor line 61. Thus, the pick-and-place part 41 can pull out multiple products A one by one from the material bin 511.

[0142] In some implementations, such as Figure 16As shown, the pick-and-place section 41 also includes a second slide rail 612 and a stop block 613. The second slide rail 612 is arranged parallel to the first slide rail 611, and one end of the second slide rail 612 extends to the side of the first slide rail 611 away from the second lifting section 63. The clamping structure 411 is slidably disposed on the second slide rail 612. The stop block 613 is disposed at the end of the first slide rail 611 away from the second lifting section 63, and a pick-up area 421 is formed between the stop block 613 and the two first slide rails 611. The first tray 512 is located in the pick-up area 421 and the edge of the first tray 512 abuts against the stop block 613. The clamping structure 411 releases the first tray 512 and moves along the second slide rail 612 in a direction away from the second lifting section 63.

[0143] Specifically, the second slide rail 612 is located between the two first slide rails 611, and there is only one of them. The stop block 613 blocks the first carrier tray 512 to prevent the first carrier tray 512 from sticking to the clamping structure 411 after it opens. At the same time, the clamping structure 411 can also avoid the product pick-up part 211.

[0144] Figure 17 This is an exploded view of the second feeding module 7 in this embodiment. Figure 18 This is a schematic diagram of the structure of the second transmission component 8 in this embodiment.

[0145] In some implementations, such as Figure 4 As shown, the pickup module 21 also includes a tray pickup unit 212, which is offset from the product pickup unit 211 in the horizontal direction.

[0146] Further reference Figures 1-3 As shown, the product conveying device also includes a second conveying component 8 and a second feeding module 7. The structure of the second feeding module 7 is similar to that of the first feeding module 4 described above. Further referencing... Figure 17 As shown, the second feeding module 7 includes a pick-and-place section 41, a first conveying assembly 42, and a plurality of second material bags 52. The plurality of second material bags 52 are disposed on the first conveying assembly 42. Each second material bag 52 includes a material bin 511 and a plurality of second carrier trays 521, with the latter disposed on the material bin 511. Further referencing... Figure 18 As shown, the pick-and-place unit 41 takes out the second tray 521 from the material bin 511 and moves it to the pick-up area 421. The tray pick-up unit 212 picks up the second tray 521 from the pick-up area 421 and moves it to the second conveying assembly 8. The product pick-up unit 211 picks up product A from the flipping table 121 and places it on the second tray 521 of the second conveying assembly 8.

[0147] Specifically, the first carrier 512 includes a first RFID tag. The second carrier 521 is provided with a second RFID tag. The second RFID tag is used to identify the second carrier 521 in the next process. The product A, which is disposed on the second transfer assembly 8, has its second side A22 facing upwards to facilitate processing of the second side A22 in the next process (e.g., setting a pattern on the second side A22).

[0148] Optionally, the second feeding module 7 in this embodiment may further include the feeding section 627, the second spacer 43, the tray conveyor line 61, the hopper conveyor line 62, and the second lifting section 63 provided in the first feeding module 4, to convey the second material package 52. That is, the first material package 51 and the hopper 511 and the hopper 511 of the second material package 52 may be configured in the same way.

[0149] In some implementations, such as Figure 5 and Figure 18 As shown, product A has multiple first positioning holes A1, and the second carrier tray 521 has a second contour groove 522 and multiple second positioning holes 523. The bottom of the second contour groove 522 is provided with multiple first positioning pins 524 corresponding to the multiple first positioning holes A1. The second conveying assembly 8 includes two third conveyor belts 81 and a fourth lifting part 82. The fourth lifting part 82 is disposed between the two third conveyor belts 81 and includes a second lifting platform 821. The top of the second lifting platform 821 is provided with multiple second positioning pins 822 corresponding to the multiple second positioning holes 523.

[0150] The fourth lifting unit 82 is configured to move the second lifting platform 821 upward, so that the second lifting platform 821 is higher than the top of the third conveyor belt 81. The tray pickup unit 212 places the second tray 521 on the second lifting platform 821, and the second positioning pin 822 passes through the corresponding second positioning hole 523 to position the second tray 521. The product pickup unit 211 places product A in the second contour groove 522, and the first positioning pin 524 passes through the corresponding first positioning hole A1 to position product A.

[0151] The fourth lifting unit 82 is also configured to lower the second lifting platform 821 so that the second tray 521 falls onto the third conveyor belt 81. The third conveyor belt 81 can then transport the second tray 521, along with product A, to the next workstation.

[0152] Optionally, the first carrier plate 512 has a first contoured groove and a plurality of the aforementioned second positioning holes 523. A plurality of the aforementioned first positioning pins 524 are provided at the bottom of the first contoured groove. The first contoured groove is adapted to the first surface A21. The aforementioned second contoured groove 522 is adapted to the second surface A22.

[0153] Figure 19 This is a flowchart illustrating the product delivery method of this embodiment.

[0154] The product conveying device in the above embodiments can be operated in the following ways, such as in some embodiments. Figure 19 As shown, the product delivery method includes:

[0155] Step S100: The conveying mechanism 2 drives the product picking unit 211 to move product A from the picking area 421 of the first feeding module 4 to the lifting platform 111.

[0156] Optionally, a cover plate (not shown in the figure) is also provided on the first carrier tray 512. The cover plate covers the upper surface of product A, preventing product A from moving within the first contour groove and ensuring the upper surface of product A remains clean. Two clamps 4111 pull the first carrier tray 512, product A, and cover plate together to the pickup area 421. In this configuration, firstly, the carrier tray pickup unit 212 picks up the cover plate and moves it upwards, away from the pickup area 421. Secondly, the pickup module 21 drives the carrier tray pickup unit 212 to rotate 180 degrees, aligning the product pickup unit 211 with the pickup area 421. Thirdly, the conveying mechanism 2 moves the pickup module 21 downwards, causing the product pickup unit 211 to pick up product A and move upwards again. Next, the pickup module 21 drives the tray pickup unit 212 to rotate 180 degrees and move downward again to place the cover plate back onto the first tray 512. Finally, the pusher block 4112 pushes the first tray 512 and the cover plate back into the hopper 511.

[0157] After step S100, the following steps are performed: the conveying mechanism 2 drives the tray picking unit 212 to move the second tray 521 of the picking area 421 of the second feeding module 7 to the second conveying assembly 8. During this process, the flipping mechanism 1 flips the product A, and the conveying mechanism 2 can use this time period to move the second tray 521 to improve the conveying efficiency.

[0158] Step S200: The moving unit 13 drives the tilting platform 121 to move above the lifting platform 111. The tilting platform 121 faces the lifting platform 111.

[0159] Step S200 includes:

[0160] The product pickup unit 211 moves product A above the vision positioning unit 9 to locate the position of product A. This ensures the movement accuracy of the conveying mechanism 2 and prevents product A from being misplaced on the lifting platform 111.

[0161] Step S300: The first lifting part 11 drives the lifting platform 111 to move upward and approach the flipping platform 121, and the flipping part 12 fixes the product A through the fixing part 1211.

[0162] Step S400: The first lifting part 11 drives the lifting platform 111 to move down, and the flipping part 12 drives the flipping platform 121 to flip up.

[0163] Step S500: The product picking unit 211 picks up product A from the flipping stage 121.

[0164] Furthermore, step S500 includes the following:

[0165] The product pickup unit 211 moves product A above the vision positioning unit 9 to reposition the product A. This ensures the movement accuracy of the transport mechanism 2 and prevents product A from being misplaced on the second tray 521.

[0166] Step S600: Place product A onto the second carrier plate 521 located in the second transfer assembly 8.

[0167] In summary, the product conveying method in this embodiment drives the flipping platform 121 to flip via the flipping part 12, and drives the lifting platform 111 to move up and down via the first lifting part 11. When the lifting platform 111 moves product A upward to approach the flipping platform 121, the fixing part 1211 can fix product A to prevent product A from falling during flipping. Thus, on the one hand, during the flipping process of product A, relative sliding between product A and the flipping mechanism 1 is prevented, and scratches on the first surface A21 and the second surface A22 of product A are prevented. On the other hand, when the product picking part 211 places product A on the lifting platform 111, the moving part 13 drives the lifting platform 111 and the flipping platform 121 to be staggered, preventing interference between the picking module 21 and the flipping mechanism 1. At the same time, this allows the product picking part 211 to approach or move away from the lifting platform 111 and the flipping platform 121 in the vertical direction, further preventing product A from being scratched.

[0168] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principle of this utility model should be included within the protection scope of this utility model.
