[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-9As shown, this embodiment provides a linear multi-station automated mounting system, including a transfer track 1. One end of the transfer track 1 is provided with a track adjustment structure 2. A first longitudinal adhesive application structure 3, a first transverse adhesive application structure 4, a second transverse adhesive application structure 5, and a second longitudinal adhesive application structure 6 with the same structure are provided according to the moving direction of the transfer track 1. The first longitudinal adjustment mechanism and the second longitudinal adjustment mechanism are respectively located on both sides of the transfer track 1. The other end of the transfer track 1 is provided with a pressing structure 7.

[0019] The first longitudinal adhesive application structure 3, the first transverse adhesive application structure 4, the second transverse adhesive application structure 5, and the second longitudinal adhesive application structure 6 each include a bracket 3-1. An adhesive application screw 3-2 is mounted on the crossbeam of the bracket 3-1. The movement of the screw controls the starting and ending positions of the adhesive application. A fixing plate 3-3 is fixed to the sliding block of the adhesive application screw 3-2. The fixing plate 3-3 is equipped with a tape roll 3-4, a pre-adhesive roller positioning plate, and a pre-adhesive roller pressing mechanism. Cylinder 3-5 and scissor mechanism positioning plate 3-6, tape roll 3-4, adhesive front roller pressing cylinder 3-5 and scissor mechanism positioning plate 3-6 are fixed on fixed plate 3-3. One end of adhesive front roller positioning plate is rotatably connected to fixed plate 3-3 through first rotating shaft 3-7. The other end of adhesive front roller positioning plate is provided with adhesive front roller 3-8. The piston rod end of adhesive front roller pressing cylinder 3-5 is hinged to the end of adhesive front roller positioning plate near adhesive front roller 3-8.

[0020] Normally, the tape head extends under the adhesive front roller 3-8. When adhesive needs to be applied, the adhesive front roller pressing cylinder presses down, and the adhesive front roller 3-8 at the front end of the cylinder presses down on the tape head, sticking it to the steel plate of the fixture. The adhesive application screw 3-2 at the adhesive application station moves under the drive of the motor, which drives the adhesive front roller 3-8 to roll the tape. The tape roll 3-4 is unwound under the rolling action of the front roller.

[0021] The scissor mechanism positioning plate 3-6 and the first rotating shaft 3-7 are located on both sides of the adhesive front roller pressing cylinder 3-5, respectively. The scissor mechanism includes scissors 3-9, a scissor cylinder, and a scissor lateral movement cylinder 3-11. The scissor cylinder 3-10 drives the scissors 3-9 to move perpendicular to the tape direction. The scissor lateral movement cylinder 3-11 is used to drive the scissors 3-9 to achieve lateral movement. The scissors 3-9 is fixedly connected to the piston rod end of the scissor cylinder 3-10. The scissor lateral movement cylinder 3-11 is fixed on the scissor mechanism positioning plate 3-6. The scissor cylinder 3-10 is fixedly connected to the piston rod end of the scissor lateral movement cylinder 3-11.

[0022] The scissor mechanism positioning plate 3-6 is fixed with a back roller pressing cylinder 3-16, and the piston end of the back roller pressing cylinder 3-16 is fixed with a back roller 3-17. The back roller 3-17 and the front roller 3-8 are located on a line parallel to the crossbeam of the bracket 3-1, and the scissors 3-9 are set perpendicular to this line.

[0023] During operation, after the front adhesive roller 3-8 travels a certain distance, the rear adhesive roller pressing cylinder 3-16 drives the rear adhesive roller 3-17 to press down, together with the front adhesive roller 3-8, to flatten the adhesive tape. After the front adhesive roller 3-8 has rolled to the designated stroke, the front adhesive roller 3-8 cylinder lifts up, and the rear adhesive roller pressing cylinder 3-16 drives the rear adhesive roller 3-17 to continue traveling a certain distance. At this time, the scissor lateral movement cylinder 3-11 moves laterally to the cutting position of the scissors 3-9. After reaching the cutting position, the scissors cylinder 3-10 drives the scissors 3-9 to cut the tape. After the tape is cut, the scissors 3-9 open, and the scissors lateral movement cylinder 3-11 returns to its original position.

[0024] The bracket 3-1 has an adhesive application lifting platform 3-12 below it, and a lifting cylinder 3-13 below the adhesive application lifting platform 3-12. The adhesive application lifting platform 3-12 is fixedly connected to the piston rod end of the lifting cylinder 3-13. A fixture blocking cylinder 3-14 is fixed to one side of the adhesive application lifting platform 3-12, and a baffle plate 3-15 is fixed to the piston rod end of the fixture blocking cylinder 3-14.

[0025] During normal adhesive application, the adhesive application lifting platform 3-12 first rises to a certain height, allowing the front adhesive roller 3-8 and the rear adhesive roller 3-17 to press onto the platform for application. Each ceramic platform has a sensor on its upper surface to determine if the steel plate on the platform track is in place. Once the sensor detects that the steel plate is in place, the platform rises to begin the adhesive application process.

[0026] When the jig steel sheet on the track enters the adhesive application station, the jig blocking cylinder 3-14 rises to block and limit the jig steel sheet. When the sensor on the adhesive application lifting platform 3-12 detects the presence of the sheet on the platform, the platform rises, and then the jig blocking cylinder 3-14 descends. After adhesive application is completed, the adhesive application lifting platform 3-12 descends to the designated position, and the next station needs to requisition the sheet, which then flows to the next station.

[0027] The pressing structure 7 includes a pressing platform 7-1. An upper pressing bracket 7-2 and a lower pressing bracket 7-3 are fixed on the upper and lower sides of the pressing platform 7-1, respectively. An upper pressing cylinder 7-4 is fixed on the upper pressing bracket 7-2, and a lower pressing motor 7-5 is fixed on the lower pressing bracket 7-3. The output end of the lower pressing motor 7-5 is connected to a lower pressing tray 7-6. The lower pressing motor 7-5 drives the lower pressing tray 7-6 to rise or fall. The lower pressing tray 7-6 corresponds to the piston rod of the upper pressing cylinder 7-4.

[0028] The lower part of the lower pressing bracket is provided with a portal-shaped bracket 7-8, and the portal-shaped bracket 7-8 is fixed to the pressing platform. The pressing platform is provided with a sliding plate 7-9 and two sliding cylinders 7-10 that drive the sliding plate 7-9 to move. The sliding cylinders 7-10 are fixed to one end of the pressing platform. Push plates 7-11 are fixedly connected to the piston rod ends of the two sliding cylinders 7-10. The push plates 7-11 are fixedly connected to the sliding plate 7-9. The other end of the pressing platform is provided with a connection to the push plates 7-11. The support hole on 1 (not visible in the figure) is matched with the support member 7-12. The sliding guide rod 7-13 and the sliding plate 7-9 are equipped with two storage boxes that match the portal frame. When the piston rod of the sliding cylinder 7-10 of the sliding guide rod 7-13 moves to the maximum stroke, one storage box is located on the lower pressing tray (i.e., the working position) directly below the portal frame 7-8. The support member 7-12 is inserted into the support hole, which serves to support and limit the sliding plate. When the piston rod of the sliding cylinder 7-10 of the sliding guide rod 7-13 moves to the minimum stroke, the other storage box is located on the lower pressing tray (i.e., the working position) directly below the portal frame 7-8.

[0029] The sliding guide rod 7-13 is provided on the pressing platform, and the sliding plate 7-9 of the sliding guide rod 7-13 is slidably connected to the sliding guide rod 7-13.

[0030] There are two storage boxes 7-7. During operation, one is in the working position (under the upper pressing cylinder), and the other is in the waiting-to-dispense position. When the raw sheets in the storage box in the working position are used up, the sliding cylinder 7-10 drives the storage box 7-7 to switch left and right. The storage box 7-7 that was originally in the working position slides to the waiting-to-dispense position, and the one that was originally in the waiting-to-dispense position slides to the working position. The storage box 7-7 can hold hundreds of products to be glued at a time. After the products to be glued are used up, they need to be manually stacked and placed back into the storage box.

[0031] During operation, after the adhesive tape is applied to all four sides of the fixture, it enters the pressing area via conveyor belt 2-3. The lower pressing motor 7-5 drives the lower pressing tray 7-6 under the work position storage box to rise. The lower pressing tray 7-6 lifts the green blank, while the upper pressing cylinder 7-4 presses down. The combined pressure from the upper and lower parts ensures that the green blank and the fixture with the adhesive tape are fully bonded together. After bonding is completed, the lower pressing motor 7-5 descends and the upper pressing cylinder 7-4 rises, completing the pressing action.

[0032] The track adjustment structure 2 includes a track conveyor motor 2-1, a track alignment motor 2-2, a conveyor belt 2-3, and a guide rod 2-4. The track conveyor motor 2-1 and the track alignment motor 2-2 are respectively fixed on two opposite upright plates of the track support 2-7. The track conveyor motor 2-1 drives the conveyor belt 2-3 to rotate, so that the fixture on the track is conveyed to the gluing station. The conveyor belt 2-3 includes a left conveyor belt and a right conveyor belt, which are respectively fixed to the left track adjustment plate 2-5 and the right track adjustment plate 2-6. The guide rod 2-4 is connected to the output shaft of the track alignment motor 2-2 and is rotatably connected to the track support 2-7. The left track adjustment plate 2-5 and the right track adjustment plate 2-6 are threadedly connected to the guide rod 2-4. The track correction motor 2-2 drives the guide rod 2-4 to rotate via a belt, which in turn moves the left track adjustment plate 2-5 and the right track adjustment plate towards or away from each other, thereby adjusting the width of the adjustment track and the position of the square fixture on the correction track, so that the fixture can be transmitted to the lower track more smoothly.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
