DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See also Figure 1-8 A robot for raising and lowering plates of seedling raising equipment comprises a main frame plate 101, a telescopic cylinder 2 and movable frame plates 102 slidably assembled at both ends of the main frame plate 101.

The transmission components A31 and B32 are used to transmit the seedling trays 4 placed thereon.

[0041] It also includes a driving motor 5 and a transmission assembly 6. The driving motor 5 is fixedly mounted on the main frame plate 101 and maintains power connection with each group of transmission assemblies A31. The transmission assembly 6 is assembled on the main frame plate 101 and the movable frame plate 102, and the transmission assembly 6 maintains power connection with the transmission assembly A31 and the transmission assembly B32.

[0042] The main frame plate 101 and the movable frame plate 102 both include a horizontally arranged bearing bottom plate 11 and limiting side plates 12 arranged on both sides of the bearing bottom plate 11. The movable frame plate 102 is arranged on the inner side of the main frame plate 101 and slides along the length direction of the main frame plate 101. For the movable frame plate 102, its outer end is also fixedly connected with a limiting end plate 13. The setting of the bearing bottom plate 11 plays a load-bearing role and ensures that the limiting side plates 12 and the limiting bottom plate are stably installed thereon. The setting of the limiting side plates 12 and the limiting end plates 13 can ensure that the seedling tray 4 to be operated on and off the plate always has the transmission components A31 and the transmission components B32 inside it for stable transmission operation.

[0043] In order to ensure that the telescopic cylinder 2, the drive motor 5, and the transmission assembly 6 can be stably assembled on the main frame plate 101 and the movable frame plate 102, various types of mounting pads or mounting pads are also fixedly connected to the main frame plate 101 and the movable frame plate 102. The setting of the mounting pads and mounting pads can ensure that the telescopic cylinder 2, the drive motor 5, and the transmission assembly 6 are stably assembled and achieve normal operation.

[0044] The movable frame 102 can be driven by the corresponding telescopic cylinder 2 to telescope on the main frame 101, so that the movable frame 102 can extend into the seedling raising equipment and receive the seedling raising tray 4 therein, and the coordinated operation of the driving motor 5 and the transmission component 6 can drive the transmission components A31 and B32 to operate synchronously and stably at the same speed, thereby driving the stable transmission of the seedling raising tray 4 carried thereon, thereby realizing the operation of raising the seedling raising tray 4 on the upper and lower sides of the seedling raising equipment.

[0045] In order to ensure that the upper and lower plate robots can effectively store the seedling trays 4 unloaded from the seedling raising equipment, or enable the upper and lower plate robots to effectively store the seedling raising trays 4 loaded onto the seedling raising equipment, and at the same time ensure that the main frame plate 101 and the movable frame plate 102 can effectively receive the stored seedling raising trays 4 and perform upper and lower plate operations, the following technical solution is provided.

[0046] It also includes a storage bracket 7, in which support frame plates 71 are evenly fixed. An assembly opening 72 is opened at the center of the support frame plate 71, and the front side of the assembly opening 72 is open. The corners of the assembly opening 72 are fixedly connected to the limiting seats 73. The seedling raising tray 4 is arranged in the assembly opening 72, and the corners of the top outer edge of the seedling raising tray 4 are nested and installed on the inner side of the limiting seats 73.

[0047] It also includes a dual-axis traveling module which is arranged at the front side of the storage bracket 7 and runs in a vertical plane rectangular coordinate system, and the main frame plate 101 is fixedly mounted on the movable part of the dual-axis traveling module.

[0048] The setting of the storage bracket 7 enables the upper and lower plate robots to effectively store a sufficient amount of seedling trays 4, wherein the support frame plates 71 distributed in a matrix are used to effectively carry the seedling trays 4 to be stored, and the limit seats 73 arranged thereon can effectively position the stored seedling trays 4. The assembly opening 72 with an open front side can ensure that the main frame plate 101, the movable frame plate 102 and the transmission components A31 and B32 thereon can lift the seedling trays 4 and output them from the front side of the assembly opening 72.

[0049] Similarly, the seedling raising equipment is also designed with a storage bracket 7 structure for storing the seedling raising trays 4. The seedling raising trays 4 can be effectively transferred between the storage bracket 7 and the seedling raising equipment by using the upper and lower plate robots.

[0050] Since the dual-axis moving module belongs to the existing technical solution and the molding equipment can be purchased on the market, it is not shown in the drawings of the specification. When the dual-axis moving module drives the main frame plate 101 and the components assembled thereon to operate synchronously, the movable frame plate 102 can be effectively docked with the bottom of each seedling tray 4 in the storage bracket 7 or the seedling raising equipment, and the seedling raising tray 4 is lifted up and output from the front side of the assembly port 72 with the help of the transmission component B32.

[0051] In order to ensure that the transmission components A31 and B32 can be stably assembled on the main frame plate 101 and the movable frame plate 102 respectively, and to ensure that the transmission components A31 and B32 can effectively carry and transmit the seedling tray 4, the following technical solution is provided.

[0052] A plurality of groups of assembly supports A14 arranged side by side are fixedly connected to the main frame plate 101 , and a plurality of groups of assembly supports B15 arranged side by side are fixedly connected to the movable frame plate 102 .

[0053] The transmission component A31 includes a synchronous belt A311 and a synchronous wheel A312 which is rotatably installed on an assembly support A14 and arranged at both ends of the main frame plate 101. The synchronous belt A311 is assembled on the periphery of two sets of synchronous wheels A312 on the same assembly support A14. The synchronous wheels A312 arranged at the same end are fixedly connected by a connecting shaft A313, and the upper side of the synchronous belt A311 is kept in contact with the top surface of the assembly support A14.

[0054] The transmission component B32 includes a synchronous belt B321 and a synchronous wheel B322 which is rotatably installed on the assembly support B15 and arranged at both ends of the main frame plate 101. The synchronous belt B321 is assembled on the periphery of two sets of synchronous wheels B322 on the same assembly support B15. The synchronous wheels B322 arranged on the same side are fixedly connected by a connecting shaft B323, and the upper side of the synchronous belt B321 is kept in contact with the top surface of the assembly support B15.

[0055] The assembly support A14 and the assembly support B15 are respectively fixedly connected to the bearing bottom plate 11 of the main frame plate 101 and the movable frame plate 102 to ensure that the synchronous wheels A312 and the synchronous wheels B322 are stably assembled thereon. In order to avoid spatial movement interference between the lower side portions of the synchronous belts A311 and B321 and the assembly support A14 and the assembly support B15, a clearance groove A141 and a clearance groove B151 are respectively opened on the inner sides of the assembly support A14 and the assembly support B15 to ensure that the lower side portion of the synchronous belt A311 is stably assembled in the clearance groove A141 and the lower side portion of the synchronous belt B321 is stably assembled in the clearance groove B151.

[0056] The upper sides of the synchronous belts A311 and B321 are supported on the top surfaces of the assembly supports A14 and B15 respectively, so that the assembly supports A14 and B15 can effectively carry the seedling tray 4 transmitted from above, thereby ensuring the stability of the transmission components A31 and B32 in transmitting the seedling tray 4.

[0057] In order to ensure that the seedling tray 4 can be stably transmitted in a straight line direction on the synchronous belts A311 and B321, a positioning groove 41 is provided at the bottom of the seedling tray 4, which is nested with the synchronous belts A311 and B321. The synchronous belts A311 and B321 are located on the inner side of the positioning groove 41 to ensure that the seedling tray 4 is stably transmitted in a straight line direction.

[0058] In order to ensure that the movable frame plate 102 can slide stably on the main frame plate 101, avoid spatial motion interference between the movable frame plate 102 and the assembly support A14 on the main frame plate 101, and avoid spatial motion interference between each connecting shaft and each assembly support, the following technical solution is provided.

[0059] A guide groove A161 is provided at the bottom of the assembly support, and a guide groove B162 is provided at the bottom of the movable frame plate 102 to maintain sliding connection with the guide groove A161; a clearance hole A171 is provided on the assembly support A14, and the connecting shaft B323 is arranged through the clearance hole A171; a clearance hole B172 is provided on the movable frame plate 102 and the assembly support B15, and the connecting shaft A313 is arranged through the clearance hole B172.

[0060] The guide groove A161 and the guide groove B162 maintain a sliding combination, which can ensure that the movable frame plate 102 can stably telescopically slide on the main frame plate 101, and can effectively avoid spatial motion interference between the movable frame plate 102 and the assembly support A14.

[0061] The provision of the clearance through holes A171 and the clearance through holes B172 can avoid spatial motion interference between the connecting shafts A313 and B323 during the assembly process.

[0062] In order to ensure that the movable frame 102 and the transmission assembly B32 assembled thereon can achieve stable upper and lower plate operations on the seedling raising tray 4, it is necessary to effectively position the seedling raising tray 4 running to the end of the movable frame 102, and the following technical solution is provided for this.

[0063] The movable frame 102 is equipped with positioning components 8 on both sides. The positioning components 8 include a mounting support 81, a positioning cylinder 82, and a guide support 83. The mounting support 81 is fixedly installed on the outer side of the movable frame 102, the positioning cylinder 82 is fixedly installed on the mounting support 81, and the guide support 83 is slidably inserted on the mounting support 81 and fixedly connected to the movable end of the positioning cylinder 82; the side wall of the seedling raising tray 4 is fixedly connected with a positioning pin seat 42, and a positioning groove 421 is opened on the positioning pin seat 42, and a positioning pin shaft 831 nested and inserted in the positioning groove 421 is fixedly connected to the guide support 83.

[0064] When the movable frame 102 runs to the bottom of the seedling raising tray 4 and receives the seedling raising tray 4, the positioning cylinder 82 is controlled to extend to drive the guide support 83 and the positioning pin 831 thereon to be inserted into the positioning groove 421 on the positioning pin seat 42 to fix the seedling raising tray 4. Then, the upper and lower disk robots and the received seedling raising tray 4 are driven upward in a small range through the dual-axis moving module to make the seedling raising tray 4 detach from the supporting frame 71, so as to facilitate the removal of the seedling raising tray 4 from the storage bracket 7 or the seedling raising equipment.

[0065] When the seedling raising tray 4 needs to be loaded into the storage bracket 7 or the seedling raising equipment, it is only necessary to perform the above-mentioned process in reverse order.

[0066] In order to ensure that the drive motor 5 can achieve power connection with the transmission component A31, ensure that the transmission component 6 is stably assembled and realize the linkage of the transmission component A31 and the transmission component B32, the following technical solution is provided.

[0067] The driving motor 5 is fixedly installed on the outside of the main frame plate 101 , and a driving bevel gear 51 is fixedly connected to the output shaft of the driving motor 5 , and a transmission bevel gear 3131 meshing with the driving bevel gear 51 is fixedly connected to the end of one set of connecting shafts A313 .

[0068] When the driving motor 5 drives the driving bevel gear 51 to operate, it can drive the transmission bevel gear 3131 and the corresponding connecting shaft A313 to operate stably, thereby driving the transmission assembly A31 to operate as a whole. Since the number of teeth of the driving bevel gear 51 is less than the number of teeth of the transmission bevel gear 3131, when the power is transmitted from the driving motor 5 to the connecting shaft A313, the effect of speed reduction and torque increase can be achieved, so that the transmission assembly A31 can stably transmit the seedling tray 4.

[0069] The transmission assembly 6 includes a mounting sleeve 61 and a spline shaft 62. The mounting sleeve 61 is rotatably mounted on the outer side of the main frame plate 101. The outer sides of the two sets of movable frame plates 102 are rotatably mounted with spline shafts 62. The spline shafts 62 are respectively slidably inserted into the two ends of the mounting sleeve 61. One set of connecting shafts A313 is fixedly connected with a No. 1 reversing bevel gear A3132, and the mounting sleeve 61 is fixedly connected with a No. 2 reversing bevel gear A611 that keeps meshing with the No. 1 reversing bevel gear A3132. Both sets of transmission assemblies B32 have a set of connecting shafts B323 fixedly connected with a No. 1 reversing bevel gear B3231, and both sets of spline shafts 62 are fixedly connected with a No. 2 reversing bevel gear B621 that keeps meshing with the corresponding No. 1 reversing bevel gear B3231.

[0070] When the transmission component A31 is operating, the combination of the No. 1 reversing bevel gear A3132 and the No. 2 reversing bevel gear A611 can drive the installation sleeve 61 to operate stably, thereby driving the two sets of spline shafts 62 to operate synchronously, and the combination of the No. 1 reversing bevel gear B3231 and the No. 2 reversing bevel gear can drive the corresponding connecting shaft B323 to operate stably, thereby driving the transmission component B32 to operate stably.

[0071] Since the spline shaft 62 can slide in the mounting sleeve 61 and always transmit power, during the telescopic sliding of the movable frame plate 102 and the transmission component B32 assembled thereon, the power of the transmission component A31 can always be transmitted to the transmission component B32.

[0072] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0073] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
