[0027] The corner pasting device 15 includes four corner pasting mechanisms 40 corresponding to the four corners of the workpiece to be processed and four corner pasting rapid prototyping die - less mechanisms located above the corner pasting mechanisms 40; each corner pasting mechanism 40 is configured with a corner pasting rapid prototyping die - less mechanism. The corner pasting rapid prototyping die - less mechanism includes a push rod 51 vertically arranged above the corner pasting mechanism 40, a first bracket 52 fixed on the corner pasting mechanism 40, and a first extension rod 53, a second extension rod 54 and a sleeve 55 with upper and lower openings, all of which are located above the corner pasting mechanism 40.

[0028] The push rod 51 is installed on the first bracket 52 through a second lifting mechanism 60. In this embodiment, the second lifting mechanism 60 includes a protective shell 69, a motor 61, a screw 62, a bearing plate 63, a second slider 64, a slide rail 65 extending in the up - and - down direction, and a first slider 66 slidably installed on the slide rail 65.

[0029] The first extension rod 53 extends in the front - and - rear direction. The rear end of the first extension rod 53 is connected to the second lifting mechanism 60.

[0030] The output shaft of the motor 61 is drivingly connected to one end of the screw 62, and the other end of the screw 62 is rotatably connected to the bearing plate 63. The motor 61 and the bearing plate 63 are both arranged on the first bracket 52. The screw 62 and the slide rail 65 are respectively located on different sides of the first bracket 52. In this embodiment, the screw 62 is located beside the slide rail 65.

[0031] A moving screw ring 67 is arranged inside the second slider 64. The moving screw ring 67 is screwed with the screw 62, and the first slider 66 is connected to the second sliding block to rise and fall with the rise and fall of the second slider 64.

[0032] The front end of the first extension rod 53 is connected to the upper end of the push rod 51. The sleeve 55 is located in front of the lifting mechanism 10 and the sleeve 55 is sleeved on the outside of the push rod 51 from the lower end of the push rod 51 upwards. The lifting mechanism 10 drives and connects the push rod 51 through the first extension rod 53 to drive the push rod 51 to rise and fall relative to the sleeve 55.

[0033] Through the cooperation of the second extension rod 53 and the sleeve 55, the push rod 51 is limited during its operation to prevent it from swinging when being collided by the corner pasting mechanism 40, ensuring the stability and reliability of the push rod 51 during use.

[0034] The second extension rod 54 extends in the front-rear direction. One end of the second extension rod 54 is connected to the first bracket 52, and the rear end of the second extension rod 54 is connected to the first bracket 52; the front end of the second extension rod 54 is connected to the sleeve 55.

One end of the adjustment member 68 is rotatably connected to the front end of the second extension rod 54, and the other end of the adjustment member 68 is rotatably connected to the sleeve 55.

[0036] A first locking member 56 for locking or loosening the adjustment member 68 and the second extension rod 54 with each other and a second locking member 57 for locking or loosening the adjustment member 68 and the sleeve 55 with each other are provided on the adjustment member 68.

[0037] In this embodiment, a third locking hole 682 for threadedly cooperating with the first locking member 56 is penetrated in one end of the adjustment member 68 in the up-down direction. A fourth locking hole 553 for threadedly cooperating with the first locking member 56 is opened downward from the upper end surface of the front end of the second extension rod 54. The first locking member 56 passes through the third locking hole 682 from top to bottom and is fitted into the fourth locking hole 553 to lock the adjustment member 68 and the second extension rod 54.

[0038] The other end of the adjustment member 68 is connected to the sleeve 55 through the second locking member 57. A limiting block 554 for ensuring that the carton forming plate is limited at the processing position is provided on the sleeve 55. A convex portion 551 protrudes from the end surface of the sleeve 55 facing the second extension rod 54, and the convex portion 551 is connected to the other end of the adjustment member 68 through the second locking member 57. Preferably, the limiting block 554 is arranged on the inner side surface of the convex portion 551. Through the limiting block 554, the conveyor belt mechanism 70 does not need to have its own limiting function, enriching the functionality of the device.

[0039] In this embodiment, a first locking hole 681 for threadedly cooperating with the second locking member 57 is penetrated in the other end of the adjustment member 68 in the up-down direction. A second locking hole 552 for threadedly cooperating with the second locking member 57 is opened downward from the upper end surface of the convex portion 551. The second locking member 57 passes through the first locking hole 681 from top to bottom and is fitted into the second locking hole 552 to lock the sleeve 55 and the adjustment member 68.

[0040] Through the error adjustment mechanism, the installation angle between the sleeve 55 and the second extension rod 54 can be further finely adjusted and fixed. Thus, even if there are machining errors and assembly errors in the adjusting member 68, the push rod, the first extension rod 53, and the second extension rod 54, the angle between the push rod 51 and the second extension rod 54 can be ensured to reach a predetermined angle by adjusting the installation angle between the sleeve 55 and the second extension rod 54 to ensure the quality of the corner pasting rapid forming.

[0041] In another embodiment, the front end of the second extension rod 54 is fixedly connected to the sleeve 55 through a first locking member 56a. Preferably, a convex portion 551a protrudes from the end face of the sleeve 55 facing the second extension rod 54, and the front end of the second extension rod 54 is fixedly connected to the convex portion 551a through the first locking member 56a.

[0043] The corner pasting mechanism 40 includes a bottom plate 41 and a corner pasting mechanism body 42 arranged on the bottom plate 41. The corner pasting mechanism body 42 is an existing corner pasting mechanism body 42 and will not be described in detail here. The vertical plate 521 stands on the bottom plate 41. Preferably, the lower end face of the vertical plate 521 is connected to the bottom plate 41. The motor 61 is connected to the upper end face of the vertical plate 521 through a motor mounting bracket 611.

[0044] The conveying device 14 includes two conveying mechanisms 141 which are arranged on the front section of the frame 10 and are relatively spaced apart.

[0045] Each conveying mechanism 141 includes a conveyor belt mechanism 70 for carrying and conveying the workpiece to be processed 110, a pallet 80 for carrying the folded edge of the workpiece to be processed 110 parallel to the moving direction of the conveyor belt mechanism 70, and a driving unit 82 for driving the conveyor belt mechanism 70 and the pallet 80 to move inwards or outwards simultaneously.

[0046] In this embodiment, the conveyor belt mechanism 70 includes a conveyor belt 71, a second driving wheel 72, a third driving wheel 73, and a driving motor 74. The conveyor belt 71 is sleeved on the second driving wheel 72 and the third driving wheel 33, and the output shaft of the driving motor 74 is connected to the second driving wheel 72.

[0047] The pallet 80 is arranged beside the conveyor belt 71. A horizontal extension portion 801 is horizontally extended inwards from the inner end face of the pallet 80, and the horizontal extension portion 801 extends into the inside of the conveyor belt 71. The upper end face of the conveyor belt 71 is higher than the upper end face of the pallet 80.

[0048] The driving unit 82 is drivingly connected to the conveyor belt mechanism 70 and the pallet 80 to drive the inner end faces of both the conveyor belt 71 and the horizontal extension part to be located on the inner and outer sides of adjacent broken lines 111 among two broken lines 111 parallel to the moving direction of the workpiece 110 to be processed at the same time.

[0049] Since the pallet 80 is located on the outer side beside the conveyor belt 71 and the upper end face of the conveyor belt 71 is higher than the upper end face of the pallet 80, the carton forming plate 110 is always supported by the pallet 80 and the conveyor belt 71 before the pressing action of the corner pasting rapid prototyping die-less mechanism, avoiding defective products caused by no support due to the failure of the corner pasting rapid prototyping die-less mechanism and improving the production quality.

[0050] The driving unit 82 includes a second slide rail 821 extending in the left-right direction, a second slider 822 slidably mounted on the second slide rail 821, and a driving cylinder 823 for simultaneously adjusting the conveyor belt mechanism 70 and the pallet 80 to approach or move away from the workpiece to be processed. Both the conveyor belt mechanism 70 and the pallet 80 are arranged on the second slider 822, and the driving cylinder 823 is drivingly connected to the second slider 822 to drive the second slider 822 to reciprocate along the second slide rail 821.

The shielding member 991 is located above the pallet 80 and the conveyor belt 71.

[0052] Through the shielding mechanism 99, the left-right folding edges of the carton forming plate 110 can be blocked, which can adapt to carton forming plates 110 with different thicknesses and also ensure the stability and reliability of the carton forming plate 110 during the conveying process.

[0053] In this embodiment, the conveyor belt mechanism 70 is connected to the pallet 80. An installation block 81 is connected to the lower end face of the pallet 80, the third transmission wheel 73 is rotatably connected to the installation block 81, and the driving motor 74 is installed on the lower end face of the pallet 80. The pallet 80 is connected to the second slider 822.

[0054] There is also a size adjustment driving unit 90 for driving one of the conveyor mechanisms to approach or move away from the other conveyor mechanism to adapt to workpieces to be processed with different widths and a size adjustment driving unit 90a for driving the other conveyor mechanism to approach or move away from one of the conveyor mechanisms to adapt to workpieces to be processed with different widths. Through the cooperation of the size adjustment driving unit 90a, carton forming plates 110 with different widths can be applied, and the flexibility is better.

[0055] In this embodiment, two transfer mechanisms 141 are symmetrically arranged at intervals on the left and right sides of the frame 10. The size adjustment drive unit 90 is used to drive the transfer mechanism on the right side to move leftward close to or rightward away from the transfer mechanism on the left side, and the size adjustment drive unit 90a is used to drive the transfer mechanism on the left side to move rightward close to or leftward away from the transfer mechanism on the right side. The structures of the size adjustment drive unit 90 and the size adjustment drive unit 90a are the same, and their actions can be synchronized under the control of the main control module. Next, the specific structure of the size adjustment drive unit 90 will be described as an example.

[0056] The size adjustment drive unit 90 includes a first driving wheel 91, an inverted T-shaped bracket 93, a flexible rotary belt 94, two first driven wheels 95, two lead screws 96, a first slide rail 901 extending along the moving direction of the transfer mechanism 141, a first slider 902 slidably mounted on the first slide rail 901, and a rotary motor 97 for driving the first driving wheel 91.

[0057] The inverted T-shaped bracket 93 is arranged on the frame 10, and includes an outer side plate 931 extending along the moving direction of the workpiece 110 to be processed and a vertical plate 932. The vertical plate 932 is connected to the middle position of the outer side plate 931. One end of each lead screw 96 is rotatably connected to the outer side plate 931, and the rotary motor 97 is arranged on the vertical plate 932. A through hole 933 is formed on the vertical plate 932, and the output shaft of the rotary motor 97 passes through the through hole 933 to drive and connect the first driving wheel 91. Two first driven wheels 95 are rotatably connected to the outer side plate 931.

[0058] A second driven wheel 98 that can rotate synchronously with the lead screw 96 is coaxially arranged on each lead screw 96. A moving plate 961 is threadedly connected to the surface of each lead screw 96, and the moving plate 961 is connected to the first slider 902.

[0059] The inner ring of the rotary belt 94 contacts the first driving wheel 91 and the two second driven wheels 98, and the outer ring of the rotary belt 94 contacts the two first driven wheels 95. The first driving wheel 91 is located between the two first driven wheels 95 and the height of the first driving wheel 91 is greater than the height of the two first driven wheels 95. The height of the two second driven wheels 98 is lower than the height of the two first driven wheels 95. The distance between the two first driven wheels 95 is less than the distance between the two second driven wheels 98. The conveyor belt mechanism 70 is respectively connected to the two moving plates 961 to displace with the corresponding moving plates 961.

[0060] In this embodiment, the moving plate 961 is connected to the second slide rail 821. The rotation motor 97 drives the first driving wheel 91 to rotate. The first driving wheel 91 drives the second driven wheel 98 to rotate through the rotary belt 94. The second driven wheel 98 drives the lead screw 96 to rotate. The lead screw 96 drives the moving plate 961 to move, and then drives the shielding mechanism 99, the conveyor belt mechanism 70 and the pallet 80 to move. Preferably, the two moving plates 961 are connected to the second slide rail 821 through a bracket.

[0061] The bracket is a U-shaped bracket 92 with an upward opening. The U-shaped bracket 92 includes a bottom plate 491 and front side plates 922 and rear side plates 923 respectively connected to the front and rear ends of the bottom plate 491. The front side plate 922 is connected to one moving plate, and the rear side plate 923 is connected to the other moving plate 961.

[0062] The driving unit 82 further includes a cross beam 824 extending in the front-rear direction. The front and rear ends of the cross beam 824 are respectively connected to the upper end faces of the front side plate 922 and the rear side plate 923. The driving cylinder 823 is arranged on the cross beam 824.

[0063] The shielding member driving unit 992 includes a motor base 993 installed on the U-shaped bracket 92, a telescopic motor 994 fixed on the motor base, a screw sleeve 995 connected to the shielding member 991, and a screw 996 passing through the screw sleeve 995 and driven by the telescopic motor 994 to rotate. When the screw 996 rotates, it drives the screw sleeve 995 to move left and right.

[0064] In this embodiment, there are two first slide rails 901 and two first sliders 902, and each first slider 902 is adapted to a first slide rail 901. The two first slide rails 901 are symmetrically arranged at intervals in the front-rear direction. The two first sliders 902 are both arranged on the lower end face of the bottom plate 491 and are symmetrically arranged at intervals in the front-rear direction respectively.

[0065] When the rotation motor 97 operates, it drives the lead screw 96 to rotate through the first driving wheel 91, the rotary belt 94 and the second driven wheel 98 in sequence, and then drives the moving plate 961 to move along the first slide rail 901, so as to drive the U-shaped bracket 92, the conveyor belt mechanism 70, the pallet 80, the driving unit 82 and the shielding mechanism 99 to move.

[0066] Each U-shaped bracket 99 is equipped with two corner attaching mechanisms 40. In this embodiment, a front-rear driving mechanism for driving the corner attaching mechanism 40 to reciprocate relative to the conveyor belt 71 and the pallet 80 along the conveyor belt moving direction is arranged on the bottom plate 991.

[0067] The bottom plate 991 is provided with two through slots 43, and each through slot 43 is provided with a front-back driving mechanism 44. The front-back driving mechanism includes a front-back rotating shaft, a front-back sliding rail, a front-back sliding block slidably mounted on the front-back sliding rail, a front-back driving motor, a driving wheel for connecting to the output shaft of the front-back driving motor, a fourth transmission wheel for transmitting power with the driving wheel, and a transmission belt sleeved on the driving wheel and the fourth transmission wheel.

[0068] The front-back rotating shaft is located in the through slot, and the front end of the front-back rotating shaft is rotatably connected to the inner front wall of the through slot. The fourth transmission wheel is sleeved on the rear end of the front-back rotating shaft. The front-back driving motor is connected to the main control module. A moving block is threadedly connected to the front-back rotating shaft, and both the moving block and the front-back sliding rail are connected to the bottom plate 41. When the driving wheel of the front-back driving motor rotates, under the action of the transmission belt, the fourth transmission wheel rotates and then drives the front-back rotating shaft. Then, the moving block rotates along the rotating shaft and displaces. At the same time, the front-back sliding block displaces along the front-back sliding rail, and the corner pasting device 15 moves with the movement of the moving block and the front-back sliding block.

[0069] By default, multiple carton forming plates 110 are stacked on the lifting plate of the lifting device 12. Next, the working principle will be briefly described: The lifting device acts first, separating the topmost carton forming plate 110 from the stop block 26. Then, the material taking device 13 sends the carton forming plate to the conveying device 14. The conveying device conveys the carton forming plate 110 to the processing location, and the corner pasting device presses down on the carton forming plate 110 and pastes the corner with adhesive tape.

[0070] The design key point of the present invention is that it mainly realizes automatic lifting of materials, automatic material taking, automatic material conveying, and automatic corner pasting by connecting the lifting device, the material taking device, the conveying device, and the corner pasting device to the main control module respectively. The whole process has a high degree of intelligence, reduces labor costs, and improves processing efficiency. Moreover, the material taking device and the lifting device are both located behind the conveying device, which is conducive to automatic material conveying and has good compactness.
