[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0046] like Figure 1 —17 embodiment,

[0047] An automatic corner protector machine includes: a tray loading mechanism 1, which is used to take out and inspect products on a tray; a conveying mechanism 3, which is used to place qualified products on the conveying mechanism 3 for transportation; a corner protector loading mechanism 4, which is used to stack corner protectors on a pre-insertion corner protector station; an automatic corner protector insertion mechanism 5, which is used to transport products to be inserted into the corners to the pre-insertion corner protector station; the conveying mechanism 3 is used to transport products to be inserted into the corners to the pre-insertion corner protector station, and the automatic corner protector insertion mechanism 5 is used to insert corner protectors into products to be inserted into the pre-insertion corner protector station; the products are transported to the conveying mechanism by the tray loading mechanism 1, and then transported to the automatic corner protector insertion mechanism 5 by the conveying mechanism for corner protector insertion processing.

[0048] The corner guard feeding mechanism 4 includes: a discharging mechanism 41; conveying the corner guards to the corner guard vibrating plate 42; the corner guard vibrating plate 42 is used to arrange and output the corner guards; a three-axis mobile platform 43; a conveying clamp 44, the conveying clamp 44 is installed on the output end of the three-axis mobile platform 43; a corner guard rack 45, which stacks and stores the corner guards from the conveying clamp 44. In this embodiment, there are four corner guard racks 45; wherein, the corner guards enter the corner guard vibrating plate 42 from the discharging mechanism 41 for arrangement, and the three-axis mobile platform 43 drives the conveying clamp 44 to clamp the arranged corner guards and place them in the corner guard racks 45 respectively;

[0049] In this embodiment, the carrying clamp 44 is connected by a rotatable cylinder, and the rotation of the cylinder drives the carrying clamp 44 to rotate in the vertical direction. The cylinder is also connected to the power output end of the servo motor installed on the three-axis mobile platform 43. The servo motor enables the carrying clamp 44 to move in the horizontal direction, so that the carrying clamp 44 can rotate in the horizontal and vertical directions after clamping the corner guard, and then combined with the three-axis mobile platform 43 to place and stack the corner guards in the corner guard rack 45, thereby realizing the loading of the corner guards.

[0050] The corner guard rack 45 includes: limit blocks 451, which are symmetrically arranged, and corner guards are stacked between adjacent limit blocks 451; a movable plate 452, which is hinged on the limit blocks 451, and the movable plate 452 and the limit blocks 451 are connected by a torsion spring; a second cylinder 453; a pushing rod 454, which is connected to the output end of the second cylinder 453; wherein the second cylinder 453 drives the pushing rod 454 to push the corresponding corner guard to move, and drives the movable plate 452 to overcome the elastic force of the torsion spring and rotate relative to the limit block 451, thereby pushing the corner guard out.

[0051] The automatic corner protection mechanism 5 includes a first clamping module 51 and a corner protection module 52. The first clamping module 51 clamps the product on the conveying mechanism 3 and moves it to the work station, and the corner protection module 52 inserts corner protection for the edges and corners of the product.

[0052] The first clamping module 51 includes: a bracket 511; a third cylinder 512, the third cylinder 512 is installed on the bracket 511; a product clamp 513, the product clamp 513 is connected to the output end of the third cylinder 512; the third cylinder 512 drives the product clamp 513 to move in the vertical direction by telescoping.

[0053] The corner protection module 52 includes: a fourth cylinder 521, which is installed on the frame; a fifth cylinder 522, which is vertically connected to the output end of the fourth cylinder 521; a rotating cylinder 523, which is installed at the output end of the fifth cylinder 522; a corner protection clamp 524, which is installed at the output end of the rotating cylinder 523; an elastic mechanism 525, one end of which is connected to a slide installed at the power output end of the fifth cylinder 522, and the other end is connected to a rotating air cylinder 525 provided on the slide. The elastic mechanism 525 can generate an elastic force to prevent the corner guard from being crushed due to excessive insertion force when the fifth cylinder 522 drives the corner guard clamping claw 524 to insert the corner guard. In this embodiment, the elastic mechanism 525 uses a spring as a power source. The elastic force generated by the elastic mechanism 525 causes the rotating cylinder 523 to move on the slide. When the rotating cylinder 523 drives the corner guard close to the product, the elastic force generated by the elastic mechanism 525 serves as the power for inserting the corner, thereby preventing the product or the corner from being damaged due to uncontrollable insertion force caused by direct cylinder drive, thereby playing a protective role.

[0054] In this embodiment, the rotating cylinder 523 drives the corner guard clamping claw 524 to rotate and move the angle because the corner guard material is relatively soft. When the corner guard clamping claw 524 clamps it, it will deform to a certain extent, which will reduce the opening of the triangular corner plug, making it difficult to insert the corner plug. If the corner plug is inserted directly, it will easily cause the corner to fail to be inserted. By rotating the corner to a certain angle so that the corner plug contacts the module, the deformed corner plug opening is expanded to its original size or slightly larger than the original size, thereby facilitating direct insertion of the corner plug.

[0055] In this embodiment, the corner guard claws 524 are divided into two, and the sides of the two corner guard claws 524 that are close to each other are provided with grooves adapted to the corner guards. When grabbing the corner guard, the corner guard is located in the groove to prevent the corner guard from being displaced during grabbing. Specifically, the two corner guard claws 524 are respectively installed on a cylinder with two power output ends. The two corner guard claws 524 are brought close to each other by the contraction of the cylinder, thereby grabbing the corner guard. The cylinder is installed on the rotating cylinder 523.

[0056] The system further includes a cardboard loading mechanism 2, which places the cardboard on one of the products in the conveying mechanism 3. In this embodiment, the cardboard is mainly used to prevent collisions between two adjacent product modules, thereby preventing damage to the product.

[0057] The conveying mechanism 3 includes: a first conveyor belt 31, which is mounted on a frame; a two-axis movable platform 32, which is mounted on a frame and is close to the end of the conveying direction of the first conveyor belt 31; a first clamp 33, which is arranged at the output end of the two-axis movable platform 32; a flip module 34, which is mounted on a frame; a linear slide 35, which is arranged on the flip module 34. One side; a loading platform 36, the loading platform 36 is connected to the output end of the linear slide 35; a pressing mechanism; wherein the two-axis mobile platform 32 drives the first clamping claw 33 to move the product on the first conveyor belt 31 to the flip module 34 and the loading platform 36, the flip module 34 moves the product to the loading platform 36, the pressing mechanism presses the product to bring the two product modules closer together to reduce the gap, and the linear slide 35 drives the loading platform 36 to transport the product to the pre-insertion corner guard station;

[0058] In this embodiment, the cardboard loading mechanism 2 first conveys the cardboard onto the product to be conveyed to the loading platform 36, and then the two products are transferred to the loading platform 36 and the turning module 34 respectively by the clamping claws. The cardboard is placed on the product transferred to the loading platform 36. When the product on the cardboard is turned over by the turning module 36 and merged with the product on the loading platform 34, the pressing mechanism located on the turning module 34 presses the product, pushing the product located in the turning module 34 onto the loading platform 36, thereby making the cardboard between the two products more flat, reducing the gap between the cardboard and the product, and facilitating the insertion of the corner protector in the subsequent steps.

[0059] The specific pressing mechanism (not shown) can use a cylinder to drive the pressing block to move and push the product out. More specifically, the contact surface of the pressing block is provided with soft materials such as rubber pads, foam, cotton cloth, etc., or the entire pressing block is made of soft rubber to prevent the product from being crushed.

[0060] In this embodiment, a soft material such as foam, rubber pad, or plastic is provided in the middle of the first clamping jaw 33 for clamping the product to prevent the cardboard of one of the products from falling off during the product transfer process. The soft material such as foam, rubber pad, or plastic exerts pressure on the cardboard, thereby ensuring that the cardboard does not fall off during the transfer process.

[0064] In this embodiment, specifically, the three-axis transfer platform can move in the X, Y, and Z directions. A suction cup is provided at the power output end of the three-axis transfer platform, which sucks the product through the suction cup and transfers it through the three-axis transfer platform. More specifically, the three-axis transfer platform is composed of a plurality of servo motors and a screw rod combination for installation. For details, reference can be made to the three-axis motion mode of a mechanical processing machine tool (machining center), which can be implemented by those skilled in the art based on the knowledge in this field.

[0065] The cardboard loading mechanism 2 includes: a second conveyor belt 21, which is installed on the frame; a visual recognition module 22, which is arranged above the second conveyor belt 21, and is used to perform visual recognition processing on the cardboard on the second conveyor belt 21; a cardboard handling module, which is installed on the frame, and the cardboard handling module transports the cardboard on the second conveyor belt 21 to the product on the conveying mechanism 3; wherein the cardboard is transported to a predetermined position by the second conveyor belt 21, and then the cardboard is visually recognized by the visual recognition module 22, and then the cardboard is transported to the product on the conveying mechanism by the cardboard handling module.

[0066] The linear slide 35 includes a sliding assembly 351, a telescopic cylinder group 352 is installed on the sliding assembly 351, a clamping cylinder 353 is installed on the telescopic cylinder group 352, and two power output ends of the clamping cylinder 353 are connected to the clamping plate 354;

[0067] The two-axis movement is achieved by the sliding component 351 and the telescopic cylinder group 352, and then the clamping cylinder 353 drives the clamping plate 354 to clamp the product.

[0068] This embodiment also includes a rotating fork synchronous belt moving component (not shown in the figure), which is arranged behind the first clamping module 51. The rotating fork synchronous belt moving component can realize movement in two-axis directions, and its output end also has a gripping clamp to clamp and transport the installed products. Through this component, the assembled products are transported to the predetermined position through the conveyor belt.

[0069] It also includes a desiccant feeding mechanism, which places the desiccant on the product with the corner protector inserted after the corner protector mechanism 5 is automatically inserted. The desiccant is vibrated by the desiccant vibration plate to arrange it in an orderly manner. The specific structure of the desiccant feeding mechanism can be implemented by a suction cup and a flat moving slide, or a robot can be used to grab and place the desiccant. In this embodiment, the former is adopted, or the same structure as the corner protector feeding mechanism 4 in this embodiment can be adopted to place the desiccant in the product.

[0072] The present invention operates as follows: First, the pallet lift 11 is activated to raise the pallet above it. After the pallet reaches a certain height, the three-axis transfer platform is activated to transfer the products on the pallet to the first conveyor belt 31. The empty pallet, which has been removed from the product, is then transferred to another pallet lift 11 for temporary storage by the transport robot 12. Next, the cardboard loading mechanism 2 transfers the cardboard onto one of the products on the first conveyor belt 31. The two-axis mobile platform 32 transfers the product onto the loading platform 36 and the flip module 34. The two-axis mobile platform 32 then transfers the product without the cardboard to the flip module 34. The flip module 34 flips and folds the product together, placing the cardboard between the two products. The assembled product (i.e., the cardboard between the two products) is then transferred to the automatic corner guard insertion mechanism 5 by the linear slide 35 for corner guard insertion. After corner guard insertion, the first clamping module 51 grips and transfers the product, placing the desiccant, and completing the packaging.
