Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone back cover processing, in particular to a mobile phone back cover magnetic ink printing production line. Background Art

[0002] In the processing of mobile phone back covers, printing is a relatively important step. The existing printing method usually uses a silk-screen magnetic ink printing production line to print the mobile phone back covers. During the printing process, the magnetic ink is first transported to the silk-screen printer through the feeding system, and then the silk-screen printer is used to print multiple mobile phone back covers placed on the template. Then the workers place the mobile phone back covers printed on the template on a tray and transfer them to a drying and conveying tunnel for rapid drying.

[0003] The existing drying and conveying tunnel includes an upper and lower conveyor chain belt, wherein the upper conveyor chain belt is arranged in opposite directions to the lower conveyor chain belt, and the feed end and the discharge end of the drying and conveying tunnel are respectively provided with a lifting and conveying mechanism for receiving the pallet and conveying the pallet to the lower conveyor chain belt or the upper conveyor chain belt, the lifting and conveying mechanism includes a row of equidistantly arranged and rotatable rollers and a linear drive mechanism for driving the rollers to translate up and down. When the pallet is transferred from the feed end of the upper conveyor chain belt to the discharge end, the worker at the discharge end takes out the template on the pallet, and then the lifting and conveying mechanism at the discharge end descends and transfers the empty pallet to the lower conveyor chain belt, and the lower conveyor chain belt transfers the pallet to the lifting and conveying mechanism at the other end, and then the lifting and conveying mechanism rises, so that the template with the back cover of the mobile phone can be placed on the pallet again, and the pallet is circulated and conveyed in the drying and conveying tunnel.

[0004] However, in actual applications, since the drying conveying tunnel and the lifting conveying mechanism are two separate devices, during docking and installation, interface gap problems often occur due to mismatch of equipment models or specifications, which in turn causes the pallet to fall or get stuck when it moves from the drying conveying tunnel to the lifting conveying mechanism.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

Detailed implementation manners

[0028] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Refer to Figures 1 to 8, A magnetic ink printing production line for a mobile phone back cover, including a drying and conveying tunnel 10 and lifting and conveying mechanisms 20 respectively arranged at the feeding end and the discharging end of the drying and conveying tunnel 10. Each of the above-mentioned lifting and conveying mechanisms 20 includes a U-shaped frame body 21. One end of the U-shaped frame body 21 with an opening faces the drying and conveying tunnel 10. Taking the end of the U-shaped frame body 21 with an opening as the front and the other end as the rear, linear driving mechanisms that move up and down synchronously are provided on the left and right inner side walls of the U-shaped frame body 21. A translation mechanism 40 is fixedly arranged between the two linear driving mechanisms. And the linear driving mechanism is also hinged with a docking mechanism for docking or separating the translation mechanism 40 from the drying and conveying tunnel 10. The docking mechanism includes a first hinge seat 51 and a second hinge seat 52 respectively protruding on the front side wall and the bottom wall of the two above-mentioned linear driving mechanisms. The first hinge seat 51 is hinged with a vertically arranged swing arm 53. A plurality of first roller shafts 54 arranged at intervals from top to bottom are rotatably connected between the two swing arms 53. And a third hinge seat 531 protrudes from the rear side wall of the swing arm 53. A cylinder 55 for driving the swing arm 53 to rotate is also hinged between the third hinge seat 531 and the second hinge seat 52.

[0030] During application, when the tray moves from the feeding end of the drying and conveying tunnel 10 to the discharging end, the cylinder 55 at this end顶升 (should be 'lifts') to drive the swing arm 53 to rotate, and then the first roller shafts 54 connected between the swing arms 53 are respectively docked with the translation mechanism 40 and the upper conveying chain belt of the drying and conveying tunnel 10. When the tray moves onto the translation mechanism 40 at the discharging end, the linear driving mechanism drives the translation mechanism 40 to descend to a position parallel to the height of the lower conveying chain belt, so that the docking mechanism is docked with the lower conveying chain belt. Then the translation mechanism 40 reverses to move the tray onto the lower conveying chain belt. Through such a setting, it is avoided that the tray drops or gets stuck during the conveying process due to the interface gap problem.

[0031] Refer to Figures 1 to 8 , The linear driving mechanism includes two vertically arranged slide rails 31. A first motor 32 and a mounting seat 33 are respectively arranged at the bottom and the top between the two slide rails 31.

And a slider 35 is also sleeved on the lead screw 34. A chute 351 that matches the shape of the slide rail 31 is recessed on the side of the slider 35 facing the slide rail 31. A support plate 36 is fixedly arranged between the two above-mentioned sliders 35. The translation mechanism 40 is arranged on the top surface of the support plate 36. Through such a setting, when the first motor 32 drives the lead screw 34 to rotate, the support plate 36 and the translation mechanism 40 fixed between the two sliders 35 move up and down accordingly.

[0032] Refer to Figures 1 to 8, the swing arm 53 is in the shape of "丩", which includes a bent portion 532 and a vertical portion 533 that are fixedly connected to each other.

The first roller shaft 54 is provided between the two vertical portions 533, and the first roller shaft 54 at the highest position between the two vertical portions 533 is flush with the translation mechanism 40. In this way, when there is no interface gap problem during the docking installation between the drying and conveying tunnel 10 and the lifting and conveying mechanism 20, the lifting and conveying mechanism 20 can also be applicable to the drying and conveying tunnel 10; the bottom end of the cylinder 55 is provided with a first hinge block 551 for hinging with the third hinge seat 531, and the output shaft of the cylinder 55 is provided with a second hinge block 552 for hinging with the second hinge seat 52. Through such a setting, the driving flexibility is increased, and at the same time, the installation space of the cylinder 55 is saved.

The channel plate 41 includes a bottom plate 411 and a first side plate 412 and a second side plate 413 that are perpendicular to the bottom plate 411 and arranged at intervals. Between the two first side plates 412, a first driving roller shaft 42, a first driven roller shaft 43, a second driving roller shaft 44, a second driven roller shaft 45, and a third driving roller shaft 46 are arranged at intervals in sequence. The right end of the first driving roller shaft 42 extends out of the right first side plate 412 and is provided with a first transmission wheel 421. A second motor 361 is fixedly arranged at the bottom of the pallet 36. The output shaft of the second motor 361 is provided with a second transmission wheel 362, and there is a slotted opening 37 above the second transmission wheel 362. The slotted opening 37 sequentially penetrates through the pallet 36 and the bottom plate 411 located on the right side of the top surface of the pallet 36. A first transmission belt 471 is connected between the first transmission wheel 421 and the second transmission wheel 362. One end of the first transmission belt 471 passes through the slotted opening 37 and is sleeved on the first transmission wheel 421, and the other end passes through the slotted opening 37 and is sleeved on the second transmission wheel 362.

[0034] The left ends of the left ends of the first driving roller shaft 42 and the second driving roller shaft 44 both extend out of the left first side plate 412 and are provided with a third transmission wheel 422 and a fourth transmission wheel 441. A second transmission belt 472 is connected between the third transmission wheel 422 and the fourth transmission wheel 441; the right ends of the right ends of the second driving roller shaft 44 and the third driving roller shaft 46 both extend out of the right first side plate and are provided with a fifth transmission wheel 442 and a sixth transmission wheel 461. A third transmission belt 473 is provided between the fifth transmission wheel 442 and the sixth transmission wheel 461. Through such a setting, when the second motor 361 drives the second transmission wheel 362 to rotate, the power is transmitted to the first transmission wheel 421 through the first transmission belt 471, thereby driving the first driving roller shaft 42 to rotate. Then, through the second transmission belt 472 and the third transmission belt 473, the second driving roller shaft 44 and the third driving roller shaft 46 are driven to rotate, and then the transfer of the tray is realized.

[0035] Reference Figures 1 to 8 A plurality of baffles 38 are convexly provided on the rear side of the support plate 36 and are arranged at intervals in the left-right direction. The baffles 38 include a horizontal plate 381 fixedly connected to the rear side of the support plate 36 and a vertical plate 382 perpendicular to the horizontal plate 381, wherein the height of the vertical plate 382 is flush with the height of the slider 35, thereby preventing the tray from falling due to inertia.

[0036] The utility model articulates a docking mechanism for docking or separating the translation mechanism 40 with the drying and conveying tunnel 10 on the linear drive mechanism of the lifting and conveying mechanism 20, and the docking mechanism includes a first hinge seat 51 and a second hinge seat 52 which are respectively protruded on the front side wall and the bottom wall of the two linear drive mechanisms, wherein the first hinge seat 51 is articulated with a vertically arranged swing arm 53, and a plurality of first rollers 54 arranged at intervals are rotatably connected between the two swing arms 53, and a third hinge seat 531 is protruded on the rear side wall of the swing arm 53, and a cylinder 55 for driving the swing arm 53 to rotate is further articulated between the third hinge seat 531 and the second hinge seat 52. Through such an arrangement, when the tray is lifted from the feeding end of the drying and conveying tunnel 10, When moving to the discharge end, the cylinder 55 at this end is lifted to drive the swing arm 53 to rotate, so that the first roller 54 connected between the swing arms 53 is respectively docked with the translation mechanism 40 and the upper conveying chain belt of the drying conveying tunnel 10. When the pallet moves to the translation mechanism 40 at the discharge end, the linear drive mechanism then drives the translation mechanism 40 to descend to a position parallel to the height of the lower conveying chain belt, and then the translation mechanism 40 is reversed to move the pallet to the lower conveying chain belt of the drying conveying tunnel 10, so that the pallet can be circulated in the drying conveying tunnel 10, and the pallet will not fall or get stuck during the transportation process due to the interface gap problem between the lifting and conveying mechanism 20 and the drying conveying tunnel 10.
