[0063] Combination Figures 1-2 The automatic two-piece box conveying and assembly production equipment provided in this embodiment of the invention is further described below. The bottom box conveying line 20 is used to convey the bottom box, and the top cover conveying line 30 is used to convey the top cover. The bottom box is conveyed by the bottom box conveying line 20 to the bottom box pushing mechanism 41, and the top cover is conveyed by the top cover conveying line 30 to the top cover fastening mechanism 42. The bottom box pushing mechanism 41 further pushes the bottom box it carries to the bottom cover fastening mechanism 42, and then the top cover is fastened to the bottom box in the bottom box pushing mechanism 41 by the top cover fastening mechanism 42. The two are fastened in a suitable position. Then, the top cover pushing mechanism 43 pushes both of them to the bottom cover biting mechanism 44. The top cover biting mechanism 44 bites the connection between the initially fastened top cover 200 and the bottom box 100, so that the two are finally connected and can ensure that the top cover 200 is flipped relative to the bottom box 100. The assembly is achieved in an automated way, with higher production efficiency and better production quality.

[0064] In one embodiment of the present invention, such as Figure 6As shown, the bottom box pushing mechanism 41 includes a bottom box pushing cylinder 411, a bottom box carrying mold 412, a bottom box pushing slider 413, and a bottom box pushing guide rail 414. The bottom box pushing guide rail 414 is horizontally installed on the frame 10 and arranged vertically near the end of the bottom box conveyor line 20.

The bottom box pushing cylinder 411 is installed on the frame 10, and its piston rod is connected and fixed to the end of the bottom box carrying mold 412. The bottom box pushing cylinder 411 pushes the bottom box carrying mold 412 forward until the bottom box in the bottom box carrying mold 412 is pushed below the top cover fastening mechanism 42. Specifically, the bottom box pushing cylinder 411 pushes the bottom box carrying mold 412 through its piston rod, guided by the cooperation of the bottom box pushing slider 413 and the bottom box pushing guide rail 414, to the end position of the bottom box conveying line 20, until the bottom box conveying line 20 conveys the bottom box onto the bottom box carrying mold 412, and then continues to be pushed by the bottom box pushing cylinder 411 to reach the bottom of the cover fastening mechanism 42 to wait for the next step.

[0065] In one embodiment of the present invention, such as Figure 7As shown, the upper cover fastening mechanism 42 includes a fastening bracket 421, an upper cover pushing cylinder 422, an upper cover bearing mold 423, and an upper cover fastening guide rail 424. The fastening bracket 421 is vertically mounted on the frame 10 and is located near the end of the upper cover conveyor line 30, and is positioned in the pushing direction of the bottom box pushing mechanism 41. The upper cover fastening guide rail 424 is vertically mounted on the fastening bracket 421. The upper cover bearing mold 423 is provided with a guide rail groove. 3. The guide rail is slidably connected to the upper cover fastening guide rail 424 via the guide rail groove and is used to carry the upper cover 200 conveyed by the upper cover conveying line 30. The upper cover pushing cylinder 422 is installed on the top of the fastening bracket 421, and its piston rod is connected and fixed to the end of the upper cover carrying mold 423. The upper cover pushing cylinder 422 pushes the upper cover carrying mold 423 downward until the upper cover in the upper cover carrying mold 423 is fastened to the bottom box in the bottom box carrying mold 412. Specifically, the cover pushing cylinder 422 pushes the cover bearing mold 423 through its piston rod, moving it downwards under the guidance of the guide rail groove and the cover fastening guide rail 424, until it reaches the end of the cover conveyor line 30. The cover 200 is then conveyed through the cover conveyor line 30 into the cover bearing mold 423. Then, the cover pushing cylinder 422 continues to push the cover 200, allowing the hinge hole 201 of the cover 200 to pass through the bent hinge piece 101 of the bottom box 100 in the box bearing mold below. At this point, the work of this step is completed.

[0066] In one embodiment of the present invention, such as Figure 8 As shown, the lid pushing mechanism 43 includes a lid support 431, a lid pushing cylinder 432, a lid pushing slider 433, and a lid pushing guide rail 434. The lid support 431 is mounted on the frame 10 and located between the ends of the bottom box conveyor line 20 and the top cover conveyor line 30. The lid pushing cylinder 432 and the lid pushing slider 433 are both connected and fixed to the lid support 431. The lid pushing guide rail 434 is slidably connected to the bottom box conveyor line 20. The lid pusher slide 433 is positioned on the lid pusher slide 433, and the extension direction of the lid pusher guide 434 is located at the intersection of the pushing directions of the bottom box pusher mechanism 41 and the top cover fastening mechanism 42. The piston rod of the lid pusher cylinder 432 is connected to the lid pusher guide 434. By driving the lid pusher guide 434 forward through the lid pusher cylinder 432, the bottom box 100 and the top cover 200, which have completed the initial fastening, can be pushed to the bottom of the lid engaging mechanism 44. Specifically, the lid pusher cylinder 432 pushes the lid pusher guide 434 forward through its piston rod, guided by its cooperation with the lid pusher slide 433, until it reaches the bottom box 100, which has completed the initial fastening, and moves it to the bottom of the lid engaging mechanism 44, awaiting the next process.

[0067] In one embodiment of the present invention, such as Figures 3-5 As shown, a bottom box guide mold 11 is provided on the frame 10 in the pushing direction of the lid push guide 434. The bottom box guide mold 11 is located below the lid engaging mechanism 44 and is used to support the bottom box 100 that has been pushed by the lid push mechanism 43 and has initially been fitted with the upper cover 200. Specifically, as the lid push guide 434 in the lid push mechanism 43 continuously pushes the bottom box with the upper cover initially fitted forward, multiple bottom boxes 100 with the upper cover 200 fitted are pushed one by one into the bottom box guide mold 11. When each bottom box 100 with the upper cover 200 fitted is pushed to the bottom of the lid engaging mechanism 44, the bent hinge piece 101 can be engaged by the lid engaging mechanism 44 to lock the hinge hole 201 through which it passes. This allows the bottom box 100 and the upper cover 200 to be hinged, and finally, the upper cover 200 can be flipped and closed relative to the bottom box 100.

[0068] In one embodiment of the present invention, such as Figures 9-12 As shown, the lid engagement mechanism 44 includes an engagement bracket 441, a support plate 442, an engagement pushing cylinder 443, an engagement pushing slider 444, an engagement pushing guide rail 445, a lid engagement cylinder 446, and an engagement assembly 447.

The biting push cylinder 443 is installed on the top of the biting bracket 441 and its piston rod is connected to the top of the support plate 442. The lid biting cylinder 446 is connected to the support plate 442 and is driven by the biting push cylinder 443 to rise and fall. The biting assembly 447 is connected to the piston rod of the lid biting cylinder 446 and is used to bite together the fastening points of the bottom box 100 and the top cover 200, which have been initially fastened together. Specifically, the bite-pushing cylinder 443 pushes the support plate 442 downward with the bite-pushing slider 444 and the bite-pushing guide rail 445 as guides, thereby driving the lid bite-pushing cylinder 446 mounted on the support plate 442 to move down to a suitable position. The bite component 447 on the lid bite-pushing cylinder 446 also moves down to a suitable position, that is, the bite component 447 moves down to the outer periphery of the curved hinge piece 101 of the bottom box. Finally, the lid bite-pushing cylinder 446 controls the bite assembly to bite the curved hinge piece 101 into the hinge hole 201 through which it passes, so that the bottom box 100 and the top cover 200 are hinged. Finally, the top cover 200 can be flipped and closed relative to the bottom box 100.

[0069] In one embodiment of the present invention, such as Figures 9-12 As shown, the lid engaging mechanism 44 also includes a cylinder seat 448, the side of which is fixed to the support plate 442.

The front occlusal block 4472 has a front T-shaped platform 44721 on its top and a front inclined surface 44722 on its outer side. The rear T-shaped platform 44731 and the front T-shaped platform 44721 are respectively adapted to be connected to the two ends of the occlusal block T-shaped groove 4482. The return spring is connected between the rear T-shaped platform 44731 and the front T-shaped platform 44721.

[0071] Further, the forked block 4471 includes a front wedge-shaped fork 44711, a rear wedge-shaped fork 44712, and a connecting block 44713 connecting the tops of the front wedge-shaped fork 44711 and the rear wedge-shaped fork 44712. The connecting block 44713 is connected to the bottom of the piston rod of the lid engagement cylinder 446. The inner surfaces of the front wedge-shaped fork 44711 and the rear wedge-shaped fork 44712 ​​facing each other are inclined surfaces. The inclined surface of the front wedge-shaped fork 44711 cooperates with the front inclined surface 44722. The inclined surface of the rear wedge fork 44712 ​​engages with the rear inclined surface 44732. When the fork block 4471 moves down, the front wedge fork 44711 and the rear wedge fork 44712 ​​respectively push the front biting block 4472 and the rear biting block 4473 to compress the spring with the biting block T-groove 4482 as a guide and achieve mutual biting. The shape of the biting part of the front biting block 4472 and the rear biting block 4473 is adapted to the shape of the fastening part of the bottom box 100 and the top cover 200.

[0072] Specifically, the lid engagement cylinder 446 drives the connecting block 44713 to move the entire fork block 4471 downward. The front wedge fork 44711 of the fork block 4471 engages with the front inclined surface 44722 of the front engagement block 4472, and the rear wedge block of the fork block 4471 engages with the rear inclined surface 44732 of the rear engagement block 4473. Thus, the downward movement of the fork block 4471 forces the front engagement block 4472 and the rear engagement block 4473 to compress the return spring between them and move towards each other. Furthermore, the movement of the front engagement block 4472 and the rear engagement block 4473 is guided by the rear T-shaped platform 44731 and the front T-shaped platform 44721 under the guidance of the engagement block T-shaped groove 4482, without deviation along the longitudinal direction. Furthermore, the shape of the engagement point between the front engagement block 4472 and the rear engagement block 4473 is adapted to the shape of the fastening point of the bottom box 100 and the top cover 200. In this way, when the front engagement block 4472 and the rear engagement block 4473 engage with the curved hinge piece 101 of the bottom box, the fully rolled hinge piece 101 can be fastened into the hinge hole 201 of the top cover 200, thus completing the hinge connection.

[0073] After completing one operation, the lid engagement cylinder 446 drives the connecting block 44713 to move the entire fork block 4471 upward. Under the action of the return spring, the rear T-shaped platform 44731 and the front T-shaped platform 44721 are forced to move outward in opposite directions under the guidance of the engagement block T-shaped groove 4482. This causes the front engagement block 4472 and the rear engagement block 4473 to open, waiting for the next engagement operation. The structure is very ingenious, can realize automated operation, and is highly practical.

[0074] In one embodiment of the present invention, such as Figure 13 As shown, the bottom box conveyor line 20 includes a bottom box conveyor bracket 21, a bottom box conveyor motor 22, a bottom box conveyor drive wheel 23, a bottom box conveyor driven wheel 24, a bottom box power belt 25, a bottom box conveyor drive shaft 26, a bottom box conveyor driven shaft 27, and a bottom box magnetic conveyor belt 28. The bottom box conveyor bracket 21 is mounted on the frame 10, and its length extends to the side of the bottom box pushing mechanism 41. The bottom box conveyor drive shaft 26 and the bottom box conveyor driven shaft 27 are respectively horizontally rotatably mounted at both ends of the bottom box conveyor bracket 21 along its length. The bottom box conveying driven wheel 24 is mounted on the bottom box conveying drive shaft 26, the bottom box conveying motor 22 is mounted on the bottom of the bottom box conveying bracket 21, the bottom box conveying drive wheel 23 is mounted on the main shaft of the bottom box conveying motor 22, the bottom box power belt 25 is wound around and connected between the bottom box conveying drive wheel 23 and the bottom box conveying driven wheel 24, and the bottom box magnetic conveyor belt 28 is wound around and connected between the bottom box conveying drive shaft 26 and the bottom box conveying driven shaft 27, and is used to magnetically convey the bottom box to the bottom box pushing mechanism 41. Specifically, the bottom box conveyor motor 22 drives the bottom box conveyor drive wheel 23 to rotate, and then drives the bottom box conveyor driven wheel 24 to rotate through the bottom box power belt 25. The bottom box conveyor driven wheel 24 drives the bottom box conveyor drive shaft 26 connected to it to rotate. Since a bottom box magnetic conveyor belt 28 is wound and connected between the bottom box conveyor drive shaft 26 and the bottom box conveyor driven shaft 27, the bottom box magnetic conveyor belt 28 can be driven to rotate. The bottom box magnetic conveyor belt 28 has a certain magnetism, which can attract the bottom box and continuously convey the bottom box along the conveying direction until the bottom box is conveyed to the bottom box bearing mold 412.

[0075] In one embodiment of the present invention, such as Figure 14As shown, the cover conveyor line 30 includes a cover conveyor bracket 31, a cover conveyor motor 32, a cover conveyor drive shaft 33, a cover conveyor driven shaft 34, and a cover magnetic conveyor belt 35. The cover conveyor bracket 31 is mounted on the frame 10 and extends along its length to the side of the bottom cover fastening mechanism 42. The cover conveyor drive shaft 33 and the cover conveyor driven shaft 34 are vertically inclined and rotatably mounted at both ends of the cover conveyor bracket 31 along its length. The cover conveyor motor 32 is mounted at the bottom of the bottom cover conveyor bracket, and its main shaft is connected to the cover conveyor drive shaft 33. The cover magnetic conveyor belt 35 is wound around and connected between the cover conveyor drive shaft 33 and the cover conveyor driven shaft 34, and is used to magnetically convey the cover to the cover fastening mechanism 42. Specifically, the cover conveyor motor 32 drives the cover conveyor drive shaft 33 connected to its main shaft to rotate. Since the cover conveyor drive shaft 33 and the cover conveyor driven shaft 34 are connected by a cover magnetic conveyor belt 35, the cover magnetic conveyor belt 35 can be controlled to rotate in one direction. During the rotation of the cover magnetic conveyor belt 35, it will magnetically attract and move the cover forward. Since the cover conveyor drive shaft 33 and the cover conveyor driven shaft 34 are respectively vertically inclined, the cover magnetic conveyor belt 35 is also inclined to a certain extent. However, because it is magnetic, it can still ensure that the conveyed cover does not fall off until the cover is conveyed into the cover bearing mold 423. Thus, the cover 200 on the cover bearing mold 423 is also inclined to a certain extent. This is to facilitate the alignment of the hinge hole 201 on it with the hinge piece 101 of the bottom box 100 below, thereby ensuring that there is space for the two to be fastened together.

[0076] Furthermore, a protective railing (not shown) can be attached to the outer side of the upper cover conveyor bracket 31. The protective railing is located outside the magnetic conveyor belt 35 of the upper cover. This can further ensure that even if the upper cover 200 is conveyed at an angle, the upper cover 200 will not fall off, and the conveying of the upper cover 200 is stable and reliable.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
