DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0042] Reference Figure 1-Figure 13 As shown, the present embodiment provides a device for automatically separating and placing seedling trays, including two structural frames 1, the two structural frames 1 are symmetrically arranged, and legs 2 are installed at the bottom of the two structural frames 1. A plurality of conveying wheels are rotatably connected between the two structural frames 1. Transverse adjustment components are embedded in the tops of the two structural frames 1, and longitudinal adjustment components are movably connected at both ends of the two transverse adjustment components. Two limiting brackets 9 are installed on the two longitudinal adjustment components, and a seedling tray is slidably connected between the four limiting brackets 9. A first size adjustment part 3 is provided in the middle of the top surface of the two structural frames 1, and the first size adjustment part 3 is rotatably connected to the transverse adjustment part. The adjusting components are meshed and connected, and two cloth plate components are fixedly connected to the top surfaces of the two structural frames 1. A supporting slide bar 12 runs through the two cloth plate components, and both ends of the supporting slide bar 12 are respectively slidably connected to the longitudinal adjustment components; the cloth plate component includes a support member 13, a sliding shaft 14 runs through the support member 13, the sliding shaft 14 is slidably connected to the support member 13, and a special-shaped support member 15 is fixedly connected to the end of the sliding shaft 14, and the special-shaped support member 15 is fixedly connected to the supporting slide bar 12, and a sub-disc upper plate component 16 is detachably connected to the top of the special-shaped support member 15, and the sub-disc upper plate component 16 is in contact with the edge 17 of the seedling raising plate.

[0043] The seedling raising tray in the present invention specifically refers to the rice seedling raising tray. The seedling raising tray has various specifications, and the size of each specification will be different. Common seedling raising tray sizes are 120cm*60cm, 80cm*40cm, and 60cm*30cm. They are selected according to different seedling raising environments and sowing requirements. The device is composed of two structural frames 1 as the bearing body, and the bottoms of the two structural frames 1 are both equipped with legs 2. Several conveying wheels rotating between the two structural frames 1 are uniformly driven by a driving motor to transport the divided seedling trays one by one to the next process. In the present invention, the two structural frames 1 are both equipped with lateral adjustment components, which can be adjusted to the required seedling raising conditions. The length of the disc, one end of the two symmetrically arranged lateral adjustment parts is connected to the longitudinal adjustment part by rotation, and the other end is connected to another longitudinal adjustment part by rotation. The longitudinal adjustment part is used to adjust to the required width of the seedling raising disc, and two limit brackets 9 are symmetrically installed on each longitudinal adjustment part. The limit brackets 9 are arranged at right angles. The four limit brackets 9 can limit the four corners of the seedling raising disc, which can facilitate the separation and placement of the seedling raising disc; by adjusting the first size adjustment part 3, the four limit brackets 9 can be adapted to the length of the seedling raising disc, and the first size adjustment part 3 is controlled by a forward and reverse ratchet (existing technology). When the lateral adjustment part needs to be adjusted When adjusting the lateral adjustment component, the positive and negative ratchets are debugged clockwise or counterclockwise. After debugging, the handles of the positive and negative ratchets are turned 90° horizontally. At this time, the handles are matched with the preset grooves on the top of the structural frame 1, which limits the passive rotation of the lateral adjustment component and avoids the precision imbalance of the lateral adjustment component. The cloth plate component can realize the upper and lower plate actions of the seedling raising plate. The supporting slide bar 12 fixedly connected to the two cloth plates is used to provide support for the cloth plate component. When adjusting the lateral adjustment component, the supporting slide bar 12 starts to slide with the limit bracket 9, and when adjusting the longitudinal adjustment component, the sliding shaft 14 slides with the support member 13. Since the seedling raising plate is light, the two supporting slides The rod 12 cooperates with the four sliding shafts 14 to support the seedling tray in the limiting bracket 9; the dividing tray upper plate component 16 can quickly separate the stacked seedling trays from the bottom one by one; in practical applications, in order to adapt to seedling trays of different sizes, it is necessary to prepare automatic dividing tray loading machines of different specifications and sizes, or it is necessary to manually perform a large number of cumbersome modifications to the existing automatic dividing tray loading machines, which is very inflexible. The present invention realizes rapid adjustment to adapt to seedling trays of different sizes through the arrangement of transverse adjustment components and longitudinal adjustment components, and the dividing tray upper plate component 16 is adjusted simultaneously with the size adjustment to achieve the effect of rapid dividing tray loading.

[0044] Further, the sub-disc upper plate component 16 includes a fixed base 1601, which is detachably connected to the special-shaped support member 15, and a fixed bracket 1602 is fixed to the top surface of the fixed base 1601, and an upper plate assembly is arranged at the lower layer of the fixed bracket 1602, and the upper plate assembly is in contact with the edge 17 of the seedling raising plate, and a sub-disc assembly is arranged at the upper layer of the fixed bracket 1602, and the sub-disc assembly is in contact with the edge 17 of the seedling raising plate. A guide baffle 1607 is fixedly connected to the side of the fixed base 1601 close to the seedling raising plate, and a downward pressing rotating cylinder 1605 is detachably connected to the guide baffle 1607, and a buffer guide plate 1606 is installed at the output end of the downward pressing rotating cylinder 1605, and the buffer guide plate 1606 is in contact with the edge 17 of the seedling raising plate.

[0045] In practical applications, the width of the edges 17 of most seedling raising trays is not very different, so the upper plate component 16 of the dividing tray in the present invention can be adapted to seedling raising trays of various sizes. When the upper plate component 16 of the dividing tray cannot be adapted to the seedling raising tray, it can be adapted by replacing the upper plate components 16 of the dividing trays of different sizes. The main difference between the upper plate components 16 of the dividing trays of different sizes lies in the vertical spacing between the upper plate assembly and the dividing plate assembly and the movement stroke of the downward pressing rotating cylinder 1605; the fixed bracket 1602 provides fixing and supporting functions for the upper plate assembly and the dividing plate assembly, and the dividing plate assembly can separate the bottom seedling raising tray of the stacked seedling raising tray, and the downward pressing rotating cylinder 1605 is used to transport the stacked seedling raising tray to the upper plate assembly; when the seedling raising tray is placed in the limiting bracket 9, the bottom seedling raising tray contacts with the buffer guide plate 1606 on the downward pressing rotating cylinder 1605, the dividing plate assembly is in a retracted state, the upper plate assembly is in an extended state, the downward pressing rotating cylinder 1605 is extended, and the buffer guide plate When the bottom seedling raising plate 1606 contacts the upper plate assembly, the stacked seedling raising plate stops moving downward. At this time, the downward pressing rotating cylinder 1605 continues to drive the seed changing guide plate to move downward for a short distance and then rotates 90°. The downward pressing rotating cylinder 1605 drives the buffer guide plate 1606 to shrink to the edge 17 of the second bottom seedling raising plate and rotates 90° in the opposite direction. At this time, the dividing plate assembly extends out, and the dividing plate assembly contacts the edge 17 of the bottom seedling raising plate while the dividing plate assembly shrinks. The bottom seedling raising plate is squeezed onto the conveying wheel and transported away. Then the dividing plate assembly shrinks and the upper plate assembly extends out at the same time. When the upper plate assembly extends out, the downward pressing rotating cylinder 1605 drives the buffer guide plate 1606 to move downward. When the buffer guide plate 1606 reaches the position of the upper plate assembly, the upper plate assembly is fully extended, and then the above actions are repeated to realize the dividing and upper plate actions. The effect of rapid dividing and upper plate can be achieved through the alternating cooperative movement of the three devices.

[0046] Further, the plate dividing assembly includes a plate dividing drive member 1604, a plate dividing shaped member 1610 is installed at the output end of the plate dividing drive member 1604, the plate dividing shaped member 1610 is in contact with the edge 17 of the seedling raising plate, the top of the plate dividing shaped member 1610 is fixedly connected to a limiting slide rail 1612, the bottom of the plate dividing shaped member 1610 is fixedly connected to a supporting slide rail 1611, the limiting slide rail 1612 and the supporting slide rail 1611 are both fixedly connected to the fixed bracket 1602, the supporting slide rail 1611 is divided into a track 1614 and a slide key 1613, and the slide key 1613 is provided with a position close to the inclined surface of the plate dividing shaped member 1610 The upper plate assembly includes an upper plate driving member 1603, an upper plate special-shaped member 1609 is installed at the output end of the upper plate driving member 1603, the upper plate special-shaped member 1609 is in contact with the edge 17 of the seedling raising plate, the top of the upper plate special-shaped member 1609 is fixedly connected to a limiting slide rail 1612, and the bottom of the upper plate special-shaped member 1609 is fixedly connected to a supporting slide rail 1611; two telescopic openings 1608 are provided on the guide baffle 1607, the dividing plate special-shaped member 1610 is slidably connected to one of the telescopic openings 1608, and the upper plate special-shaped member 1609 is slidably connected to the other telescopic opening 1608.

[0047] The tray separation driving member 1604 drives the tray separation shaped member 1610 to separate the seedling trays. In order to realize that the conventional tray separation driving member 1604 and the upper tray driving member 1603 can bear the weight of the stacked seedling trays, the upper tray and the tray separation member are made more stable and can carry more seedling trays by adding the limit slide rail 1612 and the support slide rail 1611. The tray separation shaped member 1610 is used to separate the seedling tray at the bottom. When the tray separation shaped member 1610 is separating the trays, the upper tray driving member 1603 pushes the upper tray shaped member 1610 to separate the seedling trays. 609, the upper plate shaped part 1609 carries the stacked seedling raising trays, at which time the buffer guide plate 1606 contacts the edge 17 of the second bottom seedling raising tray, and when the bottom inclined surface of the dividing plate shaped part 1610 contacts the bottom seedling raising tray, the upper plate driving part 1603 drives the upper plate shaped part 1609 to contract, and the bottom inclined surface of the dividing plate shaped part 1610 contacts the bottom seedling raising tray first and then separates the bottom seedling raising tray from the stacked seedling raising trays, at which time the dividing plate driving part 1604 drives the dividing plate shaped part 1610 to contract to complete a dividing plate upper plate action.

[0048] Specifically, the highest point of the vertical movable range of the buffer guide plate 1606 is higher than the dividing plate shaped part 1610 , and the lowest point is lower than the upper plate shaped part 1609 .

[0049] The downward pressing rotating cylinder 1605 is a customized SRC series cylinder with a stroke of: when the downward pressing rotating cylinder 1605 contracts to make the buffer guide plate 1606 at the highest point, the end of the buffer guide plate 1606 away from the output end of the downward pressing rotating cylinder 1605 is toward the seedling tray. When the buffer guide plate 1606 guides the seedling tray to stay on the upper plate special-shaped part 1609, the buffer guide plate 1606 continues to be pushed downward by the downward pressing rotating cylinder 1605, and the pushing distance is 0.6 cm. After pushing 0.6 cm, it continues to press down. The output end of the downward pressing rotating cylinder 1605 drives the buffer guide plate 1606 to rotate 90°. When the rotation reaches 90°, the downward pressing rotating cylinder 1605 begins to contract, and the downward pressing rotating cylinder 1605 The output end drives the buffer guide plate 1606 to rise to the position where the dividing plate special-shaped part 1610 contacts the seedling raising plate, and then rotates in the opposite direction by 90°. As the buffer guide plate 1606 contacts the new edge 17 of the seedling raising plate, the dividing plate driving part 1604 drives the dividing plate special-shaped part 1610 to contract, completing a guiding and buffering action. Although the current rotation angle of the downward pressure cylinder can meet the use requirements, the rotation angle project of the buffer guide plate 1606 < 90° is still being further studied. The angle is adjusted according to the length and bearing capacity of the buffer guide plate 1606 to make its rotation angle less than 90°. This can increase the working efficiency of the downward pressure rotating cylinder 1605 and reduce the wear rate, and can further improve the operation efficiency of the dividing plate upper plate device.

[0050] Further, the lateral adjustment component includes forward and reverse ball screws 4, the middle part of which is meshed with a first size adjustment part 3, the two ends of the forward and reverse ball screws 4 are respectively rotatably connected to a first movable base 5, the first movable base 5 is slidably connected to the structural frame 1, a base shaft recess is provided in the middle part of the top surface of the first movable base 5, the longitudinal adjustment component is rotatably connected to the base shaft recess, and a first scale 18 is fixedly connected to the side of the first movable base 5 away from the seedling tray.

[0051] The forward and reverse ratchets installed on the first size adjustment part 3 can be used to adjust the rotation of the screw, and the rolling threads on the screw are symmetrically set in reverse. When the forward and reverse ratchets drive the screw to rotate in one direction, the screw can drive the first movable bases 5 at both ends to move in relative or opposite directions; a rotating wheel can be optionally installed at the bottom of the first movable base 5 to make the rotating wheel rotatably connected to the structural frame 1, so that the displacement of the first movable base 5 can be adjusted more easily; when the screw is driven to rotate by the forward and reverse ratchets, the first movable bases 5 at both ends of the screw begin to move, and the lateral adjustment components installed on the other structural frame 1 do not move. At this time, the two lateral adjustment components and the two longitudinal adjustment components will form a trapezoid. After the two first movable bases 5 at this location are adjusted to the desired position, the forward and reverse ratchet handles are fixed to the groove at the top of the structural frame 1, and the other lateral adjustment component is rotated to make the two longitudinal adjustment components parallel, so that the device can adapt to the length of the seedling tray.

[0052] Further, the longitudinal adjustment component includes a support reinforcement plate 6, and longitudinal movable convex shafts are provided at the bottom of both ends of the support reinforcement plate 6. The longitudinal movable convex shafts are movably connected to the base shaft recess. A plurality of welded rotating support members 7 are fixedly connected to the top surface of the support reinforcement plate 6. The plurality of welded rotating support members 7 are rotatably connected with forward and reverse threaded screws 8. The forward and reverse threaded screws 8 are symmetrically threadedly connected with limit brackets 9, and a second scale 19 is fixedly connected to one side of the bottom of the limit bracket 9.

[0053] The longitudinal movable convex shafts at the bottom of the two ends of the reinforcing support plate are used to support the reinforcing support plate and provide rotatable support for the reinforcing support plate. When the lateral adjustment parts on one side are adjusted, the longitudinal movable convex shaft and the base shaft recess can be rotated, so that one person can adjust the device to a position suitable for the size of the seedling raising plate, which is convenient for the subsequent plate-dividing and plate-loading process; at present, this structure can adapt to seedling raising plates of conventional sizes to achieve stable support. When encountering seedling raising plates of special sizes, such as long seedling raising plates, the stacked long seedling raising plates will cause greater extrusion on the two limit brackets 9 on the reinforcing support plate. At this time, a support ball is embedded in the bottom of the support reinforcement plate near the inner side of the seedling raising plate next to the longitudinal movable convex shaft, and the bottom protrusion of the support ball is rotatably connected to the first movable base 5, which can make it more stable; a number of small wheels are installed at the bottom of the limit bracket 9, and the small wheels are rollingly connected to the reinforced support plate for strengthening The stability of the strong limit bracket 9; the two limit brackets 9 on the same side in the longitudinal direction are penetrated by a forward and reverse threaded screw 8. When the width of the device needs to be adjusted according to the width of the seedling tray, it is only necessary to rotate one end of the forward and reverse threaded screw 8 for rotation adjustment, and refer to the second scale 19 and the size position to adjust it to the required size; the end of the forward and reverse threaded screw 8 in the present invention is a cross screw groove adapted to a screwdriver, of course, it can also be set to an inner hexagonal groove, an outer hexagonal groove, a triangle, etc., which is convenient for realizing the rotation of the forward and reverse threaded screw 8; in the test, when the forward and reverse threaded screw 8 is used without additional restrictions on the forward and reverse threaded screw 8, the forward and reverse threaded screw 8 will not rotate due to the vibration transmitted from the device or other processes. If it is necessary to solve this problem, a limit key can be added to the forward and reverse threaded screw 8, and a limit groove can be added to the reinforced support plate at the corresponding position to achieve it.

[0054] Furthermore, the four limiting brackets 9 are all equipped with movable sliding buckles 11 , and the movable sliding buckles 11 are slidably connected to the supporting sliding rods 12 .

[0055] The movable slide buckle 11 is U-shaped, and one side of the movable slide buckle 11 is movably connected to the limit bracket 9. The supporting slide rod 12 is arranged parallel to the structural frame 1. When the lateral adjustment component is adjusted, the two ends of the supporting slide rod 12 slide between the movable slide buckles 11 at both ends respectively, and the supporting slide rod 12 is used to provide support for the special-shaped support member 15; because the seedling tray is generally made of plastic and is lighter as a whole, the cross-section of the supporting slide rod 12 is an ellipse that is long in the longitudinal direction and short in the transverse direction, so that it can basically carry the common stacked seedling trays; according to the weight of the common seedling tray of 60cm*30cm is 650g±5g, the weight of twenty seedling trays is about 13kg, which can be fully supported by two metal support slide rods 12.

[0056] Furthermore, a position detection component 10 is installed on any limit bracket 9, and the position detection component 10 is electrically connected to the controller.

[0057] The position detection member 10 installed on the limit bracket 9 is used to detect the remaining amount of the seedling tray in the limit bracket, and the controller will decide whether the mechanical arm is needed to add trays for the device according to the demand.

[0058] Specifically, the upper disk driving member 1603 and the sub-disk driving member 1604 are cylinders.

[0059] The upper plate driving member 1603, the sub-plate driving member 1604 and the downward pressure rotating cylinder 1605 are all cylinder series, which can reduce other configurations and is much more convenient for daily maintenance and use; among them, the upper plate driving member 1603 and the sub-plate driving member 1604 are both stroke-adjustable cylinders, model: AVENTICS R412019889.

[0060] This embodiment provides a method for automatically placing and placing seedling raising trays, comprising:

[0061] S1. Adjust the first size adjustment part 3 according to the length of the seedling tray, and adjust the limit bracket 9 to a position that matches the length of the seedling tray.

[0062] The lateral adjustment component is adjusted according to the required length of the seedling raising tray so that the lateral distance between the four limiting brackets 9 on the same side is adapted to the length of the seedling raising tray.

[0063] S2. Adjust the forward and reverse threaded screw rods 8 according to the width of the seedling raising tray, and adjust the limit bracket 9 to a position suitable for the width of the seedling raising tray.

[0064] The longitudinal adjustment component is adjusted according to the required length of the seedling raising tray so that the distance between the longitudinal same sides of the four limiting brackets 9 is adapted to the length of the seedling raising tray.

[0065] S3, the robot arm places a number of seedling trays between four limiting brackets 9.

[0066] The four limiting brackets 9 are used to limit the stacked seedling raising trays, providing conditions for the subsequent steps of detecting the number of seedling raising trays, dividing the trays, and placing the trays.

[0067] S4, the position detection element 10 transmits the detected information of the seedling raising tray to the controller through electrical connection.

[0068] The controller can realize unmanned or less-manned intelligent control, so that the upper and lower step nodes of the sub-plate and upper plate are connected.

[0069] S5. The controller drives the upper plate driving member 1603, the sub-plate driving member 1604 and the downward pressing rotating cylinder 1605 to move in coordination according to preset values, thereby driving the conveying wheel to rotate.

[0070] The preset action is to press the rotary cylinder 1605 downward to send the seedling tray to the upper plate driving member 1603, then rotate it 90 degrees to retract it and reverse it 90 degrees to support the seedling tray at the bottom. At this time, the separating plate driving member 1604 extends while the upper plate driving member 1603 contracts. When the separating plate driving member 1604 separates the seedling tray at the bottom, it begins to contract and the upper plate driving member 1603 extends. The pressing rotary cylinder 1605 descends and repeats the above process.

[0071] S6. When the height of the seedling raising tray is lower than the detection position of the position detection component 10, the position detection component 10 transmits the information to the controller through electrical connection.

[0072] The position detection part 10 is used to check whether the robot arm is performing batch loading for the device, so that the upstream and downstream devices can only be linked.

[0073] S7, the controller controls the robotic arm to grab a number of seedling trays again and place them between the four limit racks.

[0074] Robotic arms can replace manual labor to perform standardized and efficient work, providing the basic foundation for smart factories.

[0075] S8. When replacing seedling raising trays of different sizes for placing the seedlings on the trays, repeat steps S1 to S7.

[0076] When replacing seedling trays of different sizes, just adjust the lateral adjustment components and the longitudinal adjustment components to fit the seedling trays of corresponding sizes, and then you can proceed with the subsequent actions.
