[0002] Egg stacking refers to stacking or arranging eggs according to certain rules or methods to facilitate storage, transportation, or display.
[0003] Reference to the utility model patent with authorization announcement number CN222293016U, an egg palletizing device is disclosed, including a top plate, a back plate fixedly provided on the lower end face of the top plate, sliding holes on both sides of the outer wall of the back plate, sliding blocks slidably provided inside the sliding holes, clamping plates fixedly provided at one end of each sliding block, the clamping plates being symmetrically arranged, and moving blocks fixedly provided at the other end of each sliding block, each moving block having threaded holes, and lead screws provided inside the threaded holes, fixing blocks on both sides of the outer wall of the back plate, with both ends of the lead screws rotatably mounted to the fixing blocks, and a first motor provided on the outer wall of the fixing blocks, the output end of the first motor being fixedly connected to the lead screw.
[0004] The aforementioned patents cannot automatically clamp eggs at specific points when stacking them, requiring manual assistance to place them into the egg baskets. In addition, the double-sided clamping method results in poor clamping stability, and the clamping force cannot be precisely controlled. Over-clamping can damage the egg cartons containing the eggs. To address the shortcomings of the above technologies, we propose an egg finished product palletizing device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an egg palletizing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An egg palletizing device includes a multi-axis robotic arm and a palletizing assembly. The palletizing assembly includes a top plate and a bottom plate. A rotating column is rotatably mounted on the underside of the top plate, and a central support plate is fixedly mounted on the lower end of the rotating column. A cross-shaped dovetail groove is formed on the underside of the bottom plate, and four sets of clamping plates are slidably mounted inside the cross-shaped dovetail groove. A connecting folding plate is fixedly connected to the outer wall of the clamping plate. Four sets of electric push rods are fixedly mounted on the upper side of the bottom plate, and a tension sensor is fixedly mounted on the output end of the electric push rod. The outer end of the tension sensor is fixedly connected to the connecting folding plate. Several sets of photoelectric positioning sensors are arranged on the underside of the bottom plate, and several connecting columns connect the central support plate and the bottom plate.
[0008] Furthermore, a mounting plate is fixedly installed on the lower side of the output end of the multi-axis robotic arm, and the mounting top plate is screwed onto the bottom of the mounting plate.
[0009] By adopting the above technical solution, the entire palletizing assembly is installed at the bottom of the mounting plate by screwing the top plate, which facilitates disassembly and maintenance in the future.
[0010] Furthermore, a protective cover is screwed to the bottom of the mounting plate, the lower end of the protective cover is in rotatable contact with the upper side of the central bearing plate, and dustproof and heat dissipation holes are provided on the side wall of the protective cover.
[0011] Furthermore, a servo motor is provided inside the protective cover. The servo motor is fixedly installed at the bottom of the mounting plate, and a second gear is fixedly installed on the output end of the servo motor. A first gear is fixedly installed on the outer wall of the rotating column, and the first gear meshes with the second gear.
[0012] By adopting the above technical solution, starting the servo motor can activate the second gear to mesh with the first gear, thereby driving the rotating column to rotate, which in turn drives the four clamping plates on the lower side to rotate, driving them to align with the four sides of the egg basket, facilitating subsequent clamping work.
[0013] Furthermore, the second gear has fewer teeth than the first gear.
[0014] Furthermore, the clamping plate is arranged in a Z-shape, and several of the photoelectric positioning sensors are respectively fixedly installed at the four corners and the center of the bottom of the base plate.
[0015] By adopting the above technical solution, the photoelectric positioning sensor is used to provide positioning for the egg basket to be clamped, which facilitates the subsequent precise positioning and clamping work. In addition, the positioning function of the photoelectric sensor is also required for the stacking work after clamping, so as to facilitate the neat stacking of the egg baskets.
[0016] Furthermore, a rubber pad is fixedly installed on the inner side of the clamping plate, and the rubber pad has transverse anti-slip patterns.
[0017] Furthermore, a controller is fixedly installed on the upper side of the central support plate, and a transmission cable is electrically connected to the controller. A plug is fixedly installed on the upper end of the transmission cable. A power control interface is provided on the side wall of the mounting plate, and the power control interface is compatible with the size and model of the plug.
[0018] Furthermore, the four sets of rubber pads hold egg baskets inside, and several egg trays are stacked inside the egg baskets.
[0019] By adopting the above technical solution, the controller controls each electrical component in the palletizing assembly. It is electrically connected to the multi-axis robotic arm through transmission cables and plugs. Subsequent control commands from the controller can be uniformly controlled by the internal control system of the multi-axis robotic arm, thereby improving the degree of automation.
[0020] Compared with related technologies, the egg palletizing equipment proposed in this utility model has the following beneficial effects:
[0021] In this invention, an egg palletizing device is described. The palletizing assembly incorporates photoelectric positioning sensors at the four corners and center of the base plate to precisely locate the egg crates to be palletized. A robotic arm aligns the entire palletizing assembly with the egg crates, and a servo motor drives four sets of clamping plates to rotate synchronously at a certain angle, aligning them with the four sides of the egg crates. The robotic arm then lowers the four sets of clamping plates to their outer sides for clamping. During clamping, a tension sensor at the end of the electric push rod continuously senses the tension exerted by the electric push rod on the clamping plates; this tension value is the clamping force. Once each set of clamping plates reaches the appropriate clamping force, the electric push rod stops. In summary, the palletizing assembly in this invention uses a synchronous clamping method on all four sides of the egg crates, resulting in more stable clamping and precise, stable clamping force, preventing slippage or over-clamping. Furthermore, the use of multiple photoelectric positioning sensors enables precise positioning of the egg crates, eliminating the need for manual assistance. The entire process is highly automated and efficient. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figures 1-6 An egg palletizing device includes a multi-axis robotic arm 1 and a palletizing assembly 3. The palletizing assembly 3 includes a mounting top plate 31 and a bottom plate 35. A rotating column 316 is rotatably mounted on the lower side of the mounting top plate 31. A middle support plate 33 is fixedly mounted on the lower end of the rotating column 316. A cross-shaped dovetail groove 39 is opened on the lower side of the bottom plate 35. Four sets of clamping plates 310 are slidably mounted on the inner side of the cross-shaped dovetail groove 39. A connecting folding plate 313 is fixedly connected to the outer wall of the clamping plate 310. Four sets of electric push rods 314 are fixedly mounted on the upper side of the bottom plate 35. A tension sensor 315 is fixedly mounted on the output end of the electric push rod 314. The outer end of the tension sensor 315 is fixedly connected to the connecting folding plate 313. Several sets of photoelectric positioning sensors 312 are arranged on the lower side of the bottom plate 35. A mounting plate 2 is fixedly mounted on the lower side of the output end of the multi-axis robotic arm 1. The mounting top plate 31 is screwed to the bottom of the mounting plate 2. Several connecting columns 34 connect the middle support plate 33 and the bottom plate 35.
[0031] In this embodiment, a protective cover 32 is screwed to the bottom of the mounting top plate 31. The lower end of the protective cover 32 is in rotatable contact with the upper side of the middle support plate 33. Dustproof and heat dissipation holes are provided on the side wall of the protective cover 32. A servo motor 318 is provided inside the protective cover 32. The servo motor 318 is fixedly installed at the bottom of the mounting top plate 31, and a second gear 319 is fixedly installed on the output end of the servo motor 318. A first gear 317 is fixedly installed on the outer wall of the rotating column 316. The first gear 317 meshes with the second gear 319.
[0032] With the above structure, the servo motor 318 starts the second gear 319 to mesh with the first gear 317, thereby driving the rotating column 316 to rotate, driving the lower middle bearing plate 33 and the bottom plate 35 to rotate synchronously, thereby driving the four clamping plates 310 to rotate synchronously, so that the four sets of clamping plates 310 correspond to the four sides of the egg basket 4 respectively, which facilitates the subsequent clamping work.
[0033] In this embodiment, the number of teeth of the second gear 319 is less than that of the first gear 317.
[0034] With the above structure, the number of teeth of the second gear 319 is less than that of the first gear 317. When the first gear 317 rotates at a certain angle, the rotation angle of the second gear 319 is smaller. As a result, when the servo motor 318 drives the four sets of clamping plates 310 on the lower side to rotate synchronously, the rotation adjustment precision is higher.
[0035] In this embodiment, the clamping plate 310 is arranged in a Z-shape, and several photoelectric positioning sensors 312 are respectively fixedly installed at the four corners and the center of the bottom of the base plate 35.
[0036] Through the above structure, the photoelectric positioning sensor 312 is used to provide positioning for the egg basket to be clamped, which facilitates the subsequent precise positioning and clamping work. The positioning function of the photoelectric positioning sensor 312 is also needed for the multi-axis robotic arm 1 to neatly stack the egg baskets 4.
[0037] In this embodiment, a rubber pad 311 is fixedly installed on the inner side of the clamping plate 310, and the rubber pad 311 has transverse anti-slip texture.
[0038] With the above structure, the rubber pad 311 provides better stability when the clamping plate 310 holds the egg basket 4. In addition, the horizontal anti-slip texture further enhances the vertical anti-slip performance of the rubber pad 311, preventing the egg basket 4 from slipping off.
[0039] In this embodiment, a controller 36 is fixedly installed on the upper side of the central support plate 33. A transmission cable 37 is electrically connected to the controller 36. A plug 38 is fixedly installed on the upper end of the transmission cable 37. A power control interface 21 is provided on the side wall of the mounting plate 2. The power control interface 21 is compatible with the size and model of the plug 38. Four sets of rubber pads 311 hold an egg basket 4 inside. Several egg trays are stacked inside the egg basket 4.
[0040] Through the above structure, electrical connection is achieved between the multi-axis robotic arm 1 and the transmission cable 37 and plug 38. The control commands of the subsequent controller can be uniformly controlled by the internal control system of the multi-axis robotic arm 1, thereby improving the degree of automation. It should be noted that the multi-axis robotic arm 1 is a common device in existing industrial automation, and will not be described in detail here.
[0041] In a utility model, during use:
[0042] The multi-axis robotic arm 1 begins operation according to a preset program, moving the palletizing assembly 3. At this time, the photoelectric positioning sensors 312 at the four corners and center of the bottom plate 35 function, continuously emitting and receiving light to sense the precise position of the egg crates 4 to be stacked in real time. They convert the detected position information into electrical signals and transmit them to the controller 36. The controller 36 processes and analyzes these signals and sends instructions to the multi-axis robotic arm 1, guiding it to accurately align the palletizing assembly 3 with the egg crates 4. Once the palletizing assembly 3 moves to the appropriate position above the egg crates 4, the servo motor 318 inside the bottom protective cover 32 of the top plate 31 starts, causing the lower fixed middle support plate 33 and the bottom plate 35 connected to it to rotate synchronously, ultimately causing the bottom of the bottom plate 35 to cross. The four sets of clamping plates 310 in the dovetail groove 39 rotate to positions aligned with the four sides of the egg basket 4. The multi-axis robotic arm 1 controls the palletizing assembly 3 to descend, and the four sets of clamping plates 310 arranged in a Z-shape move downwards, gradually positioning themselves on the outside of the egg basket 4. At this time, the four sets of electric push rods 314 on the upper side of the base plate 35 are activated. The output end of the electric push rods 314 pushes the tension sensor 315, which in turn drives the clamping plates 310 to move towards the egg basket 4 through the connecting folding plate 313, thus beginning to clamp the egg basket 4. During the clamping process, the tension sensor 315 senses the tension provided by the electric push rods 314 to the clamping plates 310 in real time and converts the tension value into an electrical signal to be fed back to the controller 36. When each set of clamping plates 310 reaches the appropriate clamping force, the controller 36 sends a stop drive command to the electric push rod 314, and the electric push rod 314 stops working. At this time, the rubber pads 311 with transverse anti-slip texture on the inner side of the four sets of clamping plates 310 are tightly attached to the egg basket 4, ensuring that the egg basket 4 is stably clamped, which not only avoids the egg basket 4 from slipping due to insufficient clamping force, but also prevents the egg basket 4 from being damaged by excessive clamping.
[0043] After the egg crate 4 is securely gripped, the multi-axis robotic arm 1 restarts and moves the egg crate 4 to the designated area according to the preset stacking path and position. During the stacking process, the photoelectric positioning sensor 312 continues to function, detecting the accuracy of the stacking position in real time and providing precise positioning information to the multi-axis robotic arm 1, ensuring that the egg crate 4 can be stacked neatly and stably. Once the egg crate 4 is accurately placed in position, the electric push rod 314 reverses its direction, causing the clamping plate 310 to release the egg crate 4. The multi-axis robotic arm 1 then retracts the stacking assembly 3, preparing for the next stacking operation of the egg crate 4. This cycle repeats until the entire egg product stacking operation is completed.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
