[0044] like Figure 1 , Figure 2 As shown, a material tray conveying and lifting mechanism includes: a conveying component, a lifting component, a blocking component, a first X-axis translation module 6, and a second X-axis translation module 7.

The first conveyor line is mounted on a fixed vertical plate 8, and the second conveyor line is mounted on an adjusting vertical plate 9. The adjusting vertical plate 9 is mounted on a slider of a linear guide rail 10. The fixed vertical plate 8 and the linear guide rail 10 are both mounted on a mounting horizontal plate 11. The first conveyor line is a first belt conveyor line 2, and the second conveyor line is a second belt conveyor line 3. The Y-axis translation drive module is a first lead screw module. A mounting plate 14 is fixedly mounted on the side of the adjusting vertical plate 9 away from the fixed vertical plate 8, located on the mounting horizontal plate 11. The first lead screw module includes a first lead screw 15 rotatably mounted on the fixed vertical plate 8 and the mounting vertical plate 14, and a first nut 16 fixedly mounted on the adjusting vertical plate 9.

Specifically, when changing to a different sized tray 1, and adjusting the distance between the first belt conveyor line 2 and the second belt conveyor line 3 is required, the handwheel 17 is rotated, thereby driving the first lead screw 15 to rotate. The rotation of the first lead screw 15 drives the first nut 16 fixed on the adjusting vertical plate 9 to move axially along the first lead screw 15, thereby driving the adjusting vertical plate 9 to move the first belt conveyor closer to or away from the first belt conveyor line 2 along the Y-axis direction.

[0046] like Figure 5As shown, the first belt conveyor line 2 includes a first active synchronous pulley 18, multiple first driven synchronous pulleys 19, multiple first rollers 20, a first single-sided toothed synchronous belt 21 sleeved on the first active synchronous pulley 18, multiple first driven synchronous pulleys 19, and multiple first rollers 20, and a first driving member that drives the first active synchronous pulley 18 to rotate. In this embodiment, the first driving member is a first motor 22. The first active synchronous pulley 18 and multiple first driven synchronous pulleys 19 are all engaged with the tooth surface of the first single-sided toothed synchronous belt 21, and the multiple first rollers 20 are in contact with the smooth back surface of the first single-sided toothed synchronous belt 21. The belt of the first belt conveyor line 2 is the first single-sided toothed synchronous belt 21. The first belt conveyor line 2 has multiple discontinuous first synchronous belt conveying functional parts 23 formed by the first single-sided toothed synchronous belt 21 and on the same horizontal straight line, that is, the part used to convey the material tray 1. The lowest point of the first notch 24 is lower than the first synchronous belt conveying functional parts 23. The first single-sided toothed synchronous belt 21 is conveyed from below the first notch 24.

[0047] like Figure 4 As shown, the second belt conveyor line 3 includes a second active synchronous pulley 25, a plurality of second driven synchronous pulleys 26, a plurality of second rollers 27, a second single-sided toothed synchronous belt 28 sleeved on the second active synchronous pulley 25, the plurality of second driven synchronous pulleys 26, and the plurality of second rollers 27, and a second driving member that drives the second active synchronous pulley 25 to rotate. In this embodiment, the second driving member is a second motor 29. The second active synchronous pulley 25 and the plurality of second driven synchronous pulleys 26 are all engaged with the tooth surface of the second single-sided toothed synchronous belt 28, and the plurality of second rollers 27 are in contact with the smooth back surface of the second single-sided toothed synchronous belt 28. The belt of the second belt conveyor line 3 is the second single-sided toothed synchronous belt 28. The second belt conveyor line 3 has a plurality of discontinuous second synchronous belt conveying functional parts 30 formed by the second single-sided toothed synchronous belt 28 and on the same horizontal straight line, that is, the part used to convey the material tray 1. The lowest point of the second notch 31 is lower than the second synchronous belt conveying functional parts 30. The second single-sided toothed synchronous belt 28 is conveyed from below the second notch 31. A first support rod 32 supporting the first single-sided toothed synchronous belt 21 is provided below the first synchronous belt conveying function unit 23; a second support rod 33 supporting the second single-sided toothed synchronous belt 28 is provided below the second synchronous belt conveying function unit 30; the first support rod 32 and the second support rod 33 effectively prevent the single-sided toothed synchronous belt from sagging and deforming when conveying the material tray 1 by physically supporting the non-working surface of the single-sided toothed synchronous belt.

[0048] like Figures 1-3 As shown, the lifting assembly, used to lift the tray 1 on the conveying assembly, includes a first lifting module 4 and a second lifting module 5 arranged sequentially along the X-axis direction, wherein the second lifting module 5 is located at the front end of the conveying assembly in the conveying direction, i.e., as shown... Figure 1As shown, the second lifting module 5 is located to the right of the first lifting module 4; the second lifting module 5 includes a jig plate assembly and a lifting drive module for driving the jig plate assembly to rise and fall; when the jig plate assembly of the second lifting module 5 is lifted to the highest point of its lifting stroke, the material tray 1 can still be conveyed by the conveying component from below the jig plate assembly of the second lifting module 5. The first lifting module 4 and the second lifting module 5 have the same structure; the jig plate assembly is fixed on a plurality of first guide rods 34 arranged in a vertical direction, the plurality of first guide rods 34 are fixed on the lifting plate 35, and the lifting plate 35 is located below the mounting horizontal plate 11; the plurality of first guide rods 34 are all located outside the space enclosed by the fixed vertical plate 8 and the adjusting vertical plate 9. The fixture plate assembly has a first U-shaped portion and a second U-shaped portion symmetrically arranged on both sides along the Y-axis. The notch formed by the enclosed portion of the first U-shaped portion covers the belt of the first belt conveyor 2 in the vertical direction, and the notch formed by the enclosed portion of the second U-shaped portion covers the belt of the second belt conveyor 3 in the vertical direction. This arrangement enables the first lifting module 4 and the second lifting module 5 to lift the material tray 1 on the conveying assembly. The first U-shaped portion includes a first fixing part 37 parallel to the X-axis direction for fixing multiple first guide rods 34, and a first fixing part 37 parallel to the Y-axis direction and connected to the first fixing part 37. The fixed part 37 has a first connecting part 38 and a second connecting part 39 at both ends; the second U-shaped part includes a second fixing part 40 parallel to the X-axis direction for fixing multiple first guide rods 34, a third connecting part 41 parallel to the Y-axis direction and connected to both ends of the second fixing part 40; the top surface of the fixed vertical plate 8 has a first notch 24 that allows the first connecting part 38 and the second connecting part 39 to be raised and lowered; the top surface of the adjusting vertical plate 9 has a second notch 31 that allows the third connecting part 41 and the fourth connecting part 42 to be raised and lowered. In this embodiment, by setting multiple first guide rods 34 all located outside the space formed by the fixed vertical plate 8 and the adjusting vertical plate 9, and by setting the first notch 24, the second notch 31, the lowest point of the first notch 24 being lower than the first synchronous belt conveying function part 23, and the lowest point of the second notch 31 being lower than the second synchronous belt conveying function part 30, the first lifting module 4 and the second lifting module 5 can lift the material tray 1 on the conveying component. At the same time, when the fixture plate group of the second lifting module 5 is lifted to the highest point of its lifting stroke, the material tray 1 can still be conveyed by the conveying component from below the fixture plate group of the second lifting module 5.

[0049] like Figure 6As shown, the jig plate assembly includes a jig plate 36 with a flat top surface, a first clamping module and a second clamping module disposed on both sides of the jig plate 36 parallel to the X-axis direction; the first U-shaped part and the second U-shaped part are integrally disposed on the jig plate 36. The first clamping module includes a first clamping rod 43 and a fifth driving member that drives the first clamping rod 43 away from or towards the material tray 1 on the jig plate 36. In this embodiment, the fifth driving member is a first cylinder 44. The first clamping rod 43 is detachably mounted on a mounting plate, and the mounting plate is fixed on the piston rod of the first cylinder 44; the fifth driving member is mounted on the bottom surface of the jig plate 36; the material tray 1 is provided with a first slot 45 that matches the head of the first clamping rod 43 (e.g., ...). Figure 7 (As shown in the diagram) The second clamping module includes a first fixing plate 46, a first linear bearing 47 mounted on the first fixing plate 46, a second guide rod 48 sleeved in the first linear bearing 47, a second fixing plate 49 fixedly mounted on one end of the second guide rod 48, a limiting head 50 fixedly mounted on the other end of the second guide rod 48, a second clamping rod 51 detachably mounted on the second fixing plate 49, an elastic element sleeved on the second guide rod 48 and compressed between the limiting head 50 and the first linear bearing 47, and a sixth driving element that drives the first fixing plate 46 away from or towards the loading tray 1 of the fixture plate 36. In this embodiment, the elastic element is a spring 52, and the sixth driving element is a second cylinder 53. The second fixing plate 49 is located on the side of the first fixing plate 46 away from the loading tray 1 of the fixture plate 36. The loading tray 1 is provided with a second slot that matches the head of the second clamping rod 51. In this embodiment, when a loading tray 1 of a different size is replaced, the first clamping rod 43 and the second clamping rod 51 of different lengths are replaced accordingly to match the size of the loading tray 1. It should be noted that, due to the setting of spring 52, when the first clamping module and the second clamping module clamp different material trays 1, the second material rod can overcome the dimensional tolerance or wear of the material tray 1 and has a certain amount of movement in the X-axis direction (i.e., the axial direction of the second material rod), thus maintaining stable clamping of the material tray 1. In this embodiment, the working principle of the first clamping module and the second clamping module is as follows: when the material tray 1 is lifted and placed on the fixture plate 36, the piston rods of the first cylinder 44 and the second cylinder 53 extend, clamping the first clamping rod 43 at the first slot 45 of the material tray 1 and the second clamping rod 51 at the second slot of the material tray 1, thereby fixing the material tray 1 on the fixture plate 36.

[0050] like Figure 2As shown, the conveying and lifting mechanism also includes a first X-axis translation module 6 and a second X-axis translation module 7 that have the same structure and drive the first lifting module 4 and the second lifting module 5 to reciprocate along the X-axis direction. The first X-axis translation module 6 is a seventh driving member installed on the lower end surface of the mounting plate 11, and the second X-axis translation module 7 is a ninth driving member installed on the lower end surface of the mounting plate 11. In this embodiment, the seventh driving member is a first electric cylinder 12, and the ninth driving member is a second electric cylinder 13. The lifting driving module includes a first fixed horizontal plate 54 fixed on the movable part of the seventh driving member, and multiple vertical rods 5 5. A second fixed horizontal plate 56 fixed on the first fixed horizontal plate 54, an eighth driving component mounted on the second fixed horizontal plate 56, a second lead screw module, and multiple second linear bearings 59 fixed on the first fixed horizontal plate 54; the second lead screw module includes a second lead screw 57 and a second nut 58 sleeved on the second lead screw 57; the second lead screw 57 is rotatably connected to the first fixed horizontal plate 54 and the second fixed horizontal plate 56, and one end of the second lead screw 57 is connected to the eighth driving component; the lifting plate 35 is fixedly mounted on the second nut 58, and multiple first guide rods are respectively inserted into multiple second linear bearings 59. In this embodiment, the eighth driving component is a third motor 60, and the output shaft of the third motor 60 is connected to the second lead screw 57 through a synchronous pulley and a synchronous belt. In this embodiment, the function of the first X-axis translation module 6 and the second X-axis translation module 7 is to move the positions of the first lifting module 4 and the second lifting module 5 when the arm extension range of the robot is insufficient to pick up or place products in the trays 1 on the fixture plate groups of the first lifting module 4 and the second lifting module 5, so that the products in the trays 1 on the fixture plate groups of the first lifting module 4 and the second lifting module 5 are within the working range of the robot.

[0051] In this embodiment, the first lifting module 4 and the second lifting module 5 have the same structure and the same working principle. Here, the first lifting module 4 is used as an example for explanation. The working principle of the first lifting module 4 is as follows: the output shaft of the third motor 60 rotates to drive the second lead screw 57 to rotate. The rotation of the second lead screw 57 drives the second nut 58 fixed on the lifting plate 35 to rise and fall. The rise and fall of the second nut 58 drives the lifting plate 35 to rise and fall. The rise and fall of the lifting plate 35 drives the jig plate assembly fixed on the lifting plate 35 through multiple first guide rods 34 to rise and fall. The second linear bearing 59 guides the rise and fall of the jig plate assembly.

[0052] The blocking components, corresponding to the positions of the first lifting module 4 and the second lifting module 5, are used to block the material tray 1 on the conveying group from moving forward when it reaches the positions of the first lifting module 4 and the second lifting module 5. The first blocking module includes a first blocking plate 61 and a third driving component that drives the first blocking plate 61 to rise and fall. The second blocking module includes a second blocking plate 63 and a fourth driving component that drives the second blocking plate 63 to rise and fall. In this embodiment, the third driving component is a third cylinder 62 and the fourth driving component is a fourth cylinder 64. In this embodiment, two sets of the first lifting module 4 and the second lifting module 5 are provided to enable the conveying and lifting mechanism of the material tray in this embodiment to match material in two directions. That is, the material tray 1 can flow from the first lifting module 4 to the second lifting module 5, or the material tray 1 can flow from the second lifting module 5 to the first lifting module 4. In actual applications, one set of the first lifting module 4 and the second lifting module 5 is sufficient according to the flow direction of the material tray 1.

[0053] In this embodiment, the material tray 1 flows from the first lifting module 4 to the second lifting module 5. Specifically, the working principle of the material tray 1 conveying and lifting mechanism is as follows: In the initial state, the first belt conveyor line 2 and the second belt conveyor line 3 continue to operate; the fixture plate group of the first lifting module 4 is located at the lowest point of its lifting stroke, and the fixture plate group of the second lifting module 5 is located at the lowest point of its lifting stroke, that is, the fixture plate group of the first lifting module 4 and the fixture plate group of the second lifting module 5 are both located below the first synchronous belt conveying functional unit 23 and the second synchronous belt conveying functional unit 30.

[0054] (1) Remove the NG products from the first tray 1, and lift the first tray 1, after removing the NG products, onto the jig plate 36 on the second lifting module 5.

[0055] The operation begins with the first tray 1 being conveyed via the first belt conveyor 2 and the second belt conveyor 3. As the first tray 1 approaches the first lifting module 4, the third cylinder 62 drives the first blocking plate 61 to rise, stopping the first tray 1 on the first belt conveyor 2 and the second belt conveyor 3, directly above the first lifting module 4. The lifting drive module of the first lifting module 4 then drives the fixture plate assembly to rise. After the fixture plate assembly lifts the first tray 1, the first clamping module and the second clamping module of the first lifting module 4 hold the first tray 1... The first tray 1 is clamped and fixed in place; after being lifted to a predetermined height, it stops, and at the same time, the first blocking plate 61 is lowered and reset. The barcode scanner on the robotic arm scans the barcode on the tray 1. If the first tray 1 is full of OK products, the first lifting module 4 places the first tray 1 on the first belt conveyor 2 and the second belt conveyor 3 to continue flowing backward, directly to the next workstation, without stopping when passing the second lifting module 5. If the first tray 1 contains NG products, the system obtains the position of the NG products in the first tray 1, and the robotic arm removes the NG products from the first tray 1. The NG (Not Qualified) items are removed and placed in the NG item frame. Then, the lifting drive module of the first lifting module 4 drives the fixture plate assembly to descend. The first clamping module and the second clamping module of the first lifting module 4 release the first tray 1. The first lifting module 4 places the first tray 1 containing the NG items onto the first belt conveyor 2 and the second belt conveyor 3 to continue flowing backward. When the first tray 1 containing the NG items is about to be conveyed to the second lifting module 5, the fourth cylinder 64 drives the second blocking plate 63 to rise, stopping the first tray 1 containing the NG items on the first belt conveyor. The second lifting module 5 is located on the conveyor line 2 and the second belt conveyor line 3 and directly above the second lifting module 5. The lifting drive module of the second lifting module 5 drives the fixture plate group to rise. After the fixture plate group lifts up the first tray 1 after taking out the NG products, the first clamping module and the second clamping module of the second lifting module 5 clamp and fix the first tray 1 after taking out the NG products. The second lifting module 5 lifts the first tray 1 after taking out the NG products to a predetermined height and then stops. At the same time, the first blocking plate 61 descends and resets, and the first tray 1 after taking out the NG products is used as a supplementary tray 1 for OK products.

[0056] (2) Remove the NG items from the second tray 1 and fill the empty space in the second tray 1 with OK items.

[0057] The second tray 1 is conveyed via the first belt conveyor 2 and the second belt conveyor 3. When the second tray 1 is about to be conveyed to the first lifting module 4, the third cylinder 62 drives the first blocking plate 61 to rise, stopping the second tray 1 on the first belt conveyor 2 and the second belt conveyor 3, directly above the first lifting module 4. The lifting drive module of the first lifting module 4 drives the fixture plate assembly to rise. After the fixture plate assembly lifts the second tray 1, the first clamping module and the second clamping module of the first lifting module 4 clamp and fix the second tray 1. After the second tray 1 is lifted to the predetermined height, it stops, and at the same time, the first blocking plate 61 descends and resets. The barcode scanner on the robotic arm scans the barcode on the second tray 1. If the second tray 1 is full of OK products, the first lifting module 4 places the second tray 1 on the first belt conveyor 2 and the second belt conveyor 3 to continue flowing backward, directly to The next station does not stop when passing the second lifting module 5. If there are NG products in the second tray 1, the system obtains the position of the NG products in the second tray 1. The robot arm has 8 suction units. The 8 suction units pick up 7 OK products in the first tray 1. One suction unit does not pick up any products. The suction unit in the robot arm that did not pick up any products picks up one NG product in the second tray 1 and puts it on the robot arm. Then, it puts one of the 7 OK products picked up into the empty space in the second tray 1 where the NG product was taken away. When the second tray 1 is full of OK products, the lifting drive module of the first lifting module 4 drives the fixture plate group to descend. The first clamping module and the second clamping module of the first lifting module 4 release the second tray 1. The first lifting module 4 places the second tray 1, which is full of OK products, on the first belt conveyor line 2 and the second belt conveyor line 3. It continues to flow backward from below the fixture plate 36 of the second lifting module 5.
