[0044] This embodiment provides an automatic capping machine, comprising:

[0045] Workbench 1 is provided with a first workstation, a second workstation and a third workstation;

[0046] The carrier 2 is installed on the first station of the workbench 1;

[0047] The conveying mechanism 3 is installed on the second station of the workbench 1;

[0048] The cover buckling mechanism 4 is installed on the third station of the workbench 1;

[0049] The positioning mechanism 5 includes a positioning stopper 501 and a first cylinder 502 . The positioning stopper 501 and the first cylinder 502 are arranged on the conveying mechanism 3 , and the positioning stopper 501 is connected to the first cylinder 502 .

[0050] During implementation, the carrier 2 is preset on the first station of the workbench 1, and then the conveying mechanism 3 is installed on the second station, and the capping mechanism 4 is installed on the third station. The positioning stopper 501 and the first cylinder 502 in the positioning mechanism 5 and the conveying mechanism 3 are used to convey the material. The first station is the predetermined capping position. When the material is conveyed to the first station, the positioning stopper 501 will block the material on the conveying mechanism 3 from continuing to move under the push of the first cylinder 502. At this time, the material stays on the carrier 2, and then the capping mechanism 4 caps the material. The positioning stopper 501 can limit the moving position of the material on the conveying mechanism 3 to ensure that the material can accurately stay on the carrier 2.

[0051] Specifically, the positioning stopper 501 includes a stopper or a stopper rod.

[0052] In some embodiments, the automatic capping machine includes a frame, which is sleeved outside the workbench 1, and the frame is used to carry and protect the internal structure. The carrier 2 on the first station and the conveying mechanism 3 on the second station are arranged on the workbench 1, and the capping mechanism 4 on the third station is arranged on the frame and is located above the conveying mechanism 3 on the second station and the carrier 2 on the first station. The positioning mechanism 5 includes a positioning stopper 501 and a first cylinder 502. The positioning stopper 501 and the first cylinder 502 are arranged on the conveying mechanism 3, and the positioning stopper 501 is connected to the first cylinder 502; a control chassis is provided in the frame, and the control compartment is electrically connected to the conveying mechanism 3, the capping mechanism 4, and the positioning mechanism 5. A touch screen is also provided on the frame, and the touch screen is electrically connected to the control chassis. A computer stand is also provided on the frame, and a display screen, a keyboard, and a mouse are provided on the computer stand.

A perspective window is also provided on the frame, and a feed inlet and a discharge outlet are respectively provided on the frame corresponding to the starting section and the end point of the conveying mechanism 3 .

[0053] During implementation, the touch screen on the rack and the display screen, keyboard, and mouse on the computer stand can control the control chassis installed in the rack. For example, when an operation instruction is completed by touching the touch screen, the operation instruction is transmitted to the control chassis. After receiving the operation instruction, the control chassis sends a control instruction to the conveying mechanism 3, the positioning mechanism 5, and the cover-fastening mechanism 4, thereby controlling the conveying mechanism 3, the positioning mechanism 5, and the cover-fastening mechanism 4 in the rack to complete the work. When the rack is working, the internal working conditions can be observed through the perspective window. The material can enter the conveying mechanism 3 from the feed port on the rack, and then the material is covered under the action of the positioning mechanism 5 and the conveying mechanism 3. After the cover is completed, it is transmitted from the discharge port on the rack through the conveying mechanism 3.

[0054] In some embodiments, the transmission mechanism 3 comprises:

[0055] A first track plate 301;

[0056] A second track plate 302 is arranged parallel to and spaced from the first track plate 301 , and the carrier 2 is arranged between the first track plate 301 and the second track plate 302 ;

[0057] The first conveyor belt 303 is fixed on the first track plate 301 through a first conveyor wheel set;

[0058] The second conveyor belt 304 is fixed on the second track plate 302 through a second conveyor wheel set;

[0059] The transmission motor 305 has a transmission shaft 306 at its output end, and the transmission shaft 306 is connected to the first transmission wheel set and the second transmission wheel set.

[0060] During implementation, the first track plate 301 and the second track plate 302 are arranged in parallel and spaced apart, so there is a conveying space between the first track plate 301 and the second track plate 302, and the carrier 2 is arranged in the conveying space between the first track plate 301 and the second track plate 302, and the conveying motor 305 drives the transmission shaft 306 to rotate, and the rotation of the transmission shaft 306 drives the first conveying wheel group and the second conveying wheel group to rotate synchronously, and the first conveyor belt 303 on the first conveying wheel group and the second conveyor belt 304 of the second conveying wheel group move on the first conveying wheel group and the second conveyor belt 304 respectively. When the conveying mechanism 3 conveys materials, both sides of the materials are respectively carried on the first conveyor belt 303 and the second conveyor belt 304, and the first conveyor belt 303 and the second conveyor belt 304 synchronously drive the materials forward. When the materials advance to the position through the positioning mechanism 5, the materials stay on the carrier 2 to complete the capping process, and when the capping is completed, the first conveyor belt 303 and the second conveyor belt 304 drive the materials to transfer.

[0061] Specifically, the first transmission wheel group and the second transmission wheel group have the same structure, including a driving wheel and a plurality of driven wheels, a first bearing seat is provided on the first track plate 301, a through hole is provided on the first bearing seat, a rolling bearing is provided in the through hole of the first bearing seat, the driving wheel of the first transmission wheel group is arranged at the through hole of the first bearing seat, a second bearing seat is provided on the second track plate 302, a through hole is provided on the second bearing seat, a rolling bearing is provided in the through hole of the second bearing seat, the driving wheel of the second transmission wheel group is arranged at the through hole of the second bearing seat, the transmission shaft 306 passes through the rolling bearing on the second bearing seat, then passes through the driving wheel of the second transmission wheel group on the second bearing seat, then passes through the driving wheel of the first transmission wheel group on the first bearing seat, and finally passes through the rolling bearing in the through hole of the first bearing seat, so that the transmission shaft 306 synchronously drives the driving wheel of the first transmission wheel group and the second transmission wheel group.

[0062] In some embodiments, the positioning mechanism 5 also includes a second cylinder 503 and a pusher 504, the second cylinder 503 and the pusher 504 are arranged on the second track plate 302, the second cylinder 503 is connected to the pusher 504, the first track plate 301 is provided with a positioning stopper 501 and the first cylinder 502, and the second track plate 302 is also provided with a positioning stopper 501 and the first cylinder 502.

[0063] During implementation, the second cylinder 503 and the pusher 504 are installed on the second track plate 302, and the second cylinder 503 is connected to the pusher 504. Then, the positioning stopper 501 and the first cylinder 502 are respectively installed on the first track plate 301 and the second track plate 302. When the material moves on the conveying mechanism 3, the positioning stopper 501 on the first track plate 301 and the second track plate 302 rises under the push of the first cylinder 502 to block the advancement of the material. When the material needs to be pushed sideways to accurately reach the first station, the pusher 504 on the second track plate 302 will move the material sideways to the first station under the push of the second cylinder 503, and the pusher 504 plays a role in assisting the positioning of the material.

[0064] Specifically, two positioning stops 501 are provided on the first track plate 301, each positioning stop 501 is connected to a first cylinder 502, and two positioning stops 501 are provided on the second track plate 302, each positioning stop 501 is provided with a first cylinder 502, and the positioning stops 501 on the first track plate 301 correspond to the positioning stops 501 on the second track plate 302 in pairs. When the material is on the carrier 2 of the first station, a positioning stop 501 on the first track plate 301 abuts against the rear side of the material, and a positioning stop 501 on the second track plate 302 also abuts against the rear side of the material, and another positioning stop 501 on the first track plate 301 abuts against the front side of the material. Similarly, another positioning stop 501 on the second track plate 302 abuts against the front side of the material. The four positioning stops 501 respectively abut against the material. The front and rear sides of the material, in addition to limiting the movement and positioning of the material, can also prevent the material from being offset when the material is covered; a fixed plate 505 is provided on the second track plate 302, and the second cylinder 503 is installed on the fixed plate 505. The pusher 504 includes a pusher plate and a pusher block. The pusher plate is connected to the second cylinder 503, and the pusher block is arranged on the pusher plate. An opening corresponding to the position of the pusher block is provided on the second track plate 302. When the pusher 504 is in the initial position, the pusher block is located on one side of the second track plate 302. When it is necessary to push the material, the pusher block passes through the opening on the second track plate 302 to resist the material and shift the material, that is, the pusher 504 does not affect the movement of the material on the conveying mechanism 3 when it is in the initial position. When the pusher 504 is needed to push the material, the pusher block on the pusher 504 passes through the opening on the second track plate 302 to push the material.

[0065] In some embodiments, the first track plate 301 is fixedly connected to the workbench 1 , the second track plate 302 is movably connected to the workbench 1 , the carrier 2 is movably connected to the workbench 1 , and a pushing component is provided on the workbench 1 , which connects the carrier 2 and the second track plate 302 .

[0066] During implementation, when it is necessary to cap materials of different specifications, it is necessary to adjust the distance between the first workstation and the first track plate 301 and the second track plate 302. The second track plate 302 is movably connected to the workbench 1. The pushing component can push the second track plate 302 closer to or away from the first track plate 301, so as to adjust the distance between the first track plate 301 and the second track plate 302. The carrier 2 is also movably connected to the workbench 1. The pushing component can push the carrier 2 to move the position of the carrier 2 on the workbench 1. The position movement of the carrier 2 corresponds to the change of the first workstation, thereby adjusting the first workstation.

[0067] Specifically, a guide rail is provided on the workbench 1, and a plurality of sliders are provided on the guide rail. The second track plate 302 and the carrier 2 are respectively arranged on different sliders. The sliding direction of the slider is perpendicular to the moving direction of the conveyor belt. The pushing component can push the carrier 2 and the second track plate 302 to move on the guide rail.

[0068] In some embodiments, the push assembly includes:

[0069] First screw rod;

[0070] A hand wheel is mounted on one end of the first screw rod;

[0071] A first screw nut, sleeved on the first screw and connected to the second track plate 302;

[0072] The second screw nut is sleeved on the first screw, and the carrier 2 is movably connected to the workbench 1 , and the second screw nut is connected to the carrier 2 .

[0073] During implementation, when it is necessary to adjust the position of the carrier 2 and the distance between the first track plate 301 and the second track plate 302, the hand wheel is manually turned to rotate the first screw rod. When the first screw rod rotates, the first screw nut and the second screw nut both move on the first screw rod, so that the first screw nut drives the second track plate 302, and the second screw nut drives the carrier 2, ultimately achieving the adjustment of the position of the carrier 2 and the distance between the first track plate 301 and the second track plate 302.

[0074] In some embodiments, the positioning mechanism 5 further includes:

[0075] A positioning ejector pin is mounted on the carrier 2;

[0076] The third cylinder is installed at the bottom of the carrier 2 and is drivingly connected to the carrier 2 .

[0077] During implementation, a positioning hole corresponding to the position of the positioning ejector pin is usually provided on the material. When the material reaches the carrier 2, the positioning ejector pin can pass through the positioning hole on the material to position the material on the carrier 2. The positioning ejector pin can position the material while ensuring the stability of the material on the carrier 2. When the material is covered on the carrier 2, the third cylinder drives the carrier 2 to descend so that the positioning ejector pin on the carrier 2 is pulled out from the positioning hole on the material. At this time, the material is transferred through the conveying mechanism 3.

When the cover is fastened on the material, the X-axis driving device 403 and the Y-axis driving device 404 can cooperate with each other to move the cover-fastening assembly on the movable plate 401 to above the first station. When the cover-fastening assembly moves to above the first station, the Z-axis driving device 405 drives the mounting seat 402 to move in the Z-axis direction of the movable seat, and the mounting seat 402 drives the cover-fastening assembly to move in the Z-axis direction.

When the support plate 411 needs to be replaced, the locking bolt (not shown in the figure) is loosened but not removed from the locking bolt on the rotating shaft 409. The tightening screw hole 410 is unscrewed, and then the locking bolt (not shown in the figure) is rotated out of the locking groove 412 of the support plate 411 with the rotating shaft 409 as the center. At this time, the support plate 411 is removed from the pin (not shown in the figure) and then the support plate 411 is replaced.

When the pressure is excessively pressed, the pressure head seat 417 will be on the guide shaft 416, and the spring 415 on the guide shaft 416 will resist the pressure head seat 417. The spring 415 can allow the pressure head seat 417 to maintain a certain downward force while preventing the pressure head seat 417 from being excessively pressed, thereby preventing the material from being crushed.

[0094] In some embodiments, a laser ranging sensor is provided on the workbench 1 .

[0095] During implementation, it is necessary to measure the distance between the capping assembly and the first station before work begins, and measure the distance between the capping assembly and the first station through a laser ranging sensor to ensure the distance accuracy when the capping assembly caps the material.

[0096] In some embodiments, a barcode scanner is provided on the workbench 1 , and the barcode scanner is fixed on the workbench 1 by a support fixing clamp.

[0097] During implementation, a specific QR code is preset on each material, and the barcode scanner scans the QR code on the material to identify that the material has been covered.

[0098] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
