Description

Technical Field

[0002] A packaging box is a box used to package products. It can ensure the safety of products and improve the quality of products. It is widely used in electronics, food, cosmetics and other industries. Common packaging boxes include paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. Manufacturers choose corresponding packaging boxes according to different products and needs. In manufacturing, after placing the product in the box body, the box cover is placed on the box body, and edge banding is attached to the box cover and the box body to ensure the integrity of the box, which can also play a certain anti-counterfeiting role.

[0003] For some product packaging boxes, the lid is completely surrounded by the side wall of the box body. To ensure the integrity of the lid's appearance, some manufacturers need to attach part of the edge banding to the inner wall of the lid. After the lid and the box body are assembled, the other part is bent and attached to the box body. At present, the edge banding is done manually. During the attachment process, the opening of the lid needs to face upwards. After attachment, the edge banding is prone to tipping over or even bending, resulting in creases, which affects the effect of subsequent attachment to the box body. At the same time, the whole process is time-consuming and labor-intensive, and inefficient.

[0057] like Figures 1 to 7 As shown, this embodiment provides a device for attaching materials to the inner side wall of a box-shaped workpiece, wherein the first workpiece is a box-shaped structure, having a box top wall 1100 and two oppositely arranged box side walls 1200, and the device for attaching materials to the inner side wall of the box-shaped workpiece is used to attach the second workpiece to the inner side of the box side wall 1200 of the first workpiece, wherein, in this embodiment, the first workpiece is a box cover 1000, which can be covered on the outer periphery of the box body, the top of the box cover 1000 forms the box top wall 1100, and the side walls of the box cover 1000 form the box side walls 1200, and the second workpiece is an edge banding strip 2000.

[0058] The device for pasting the inner wall of a box-shaped workpiece includes a frame 100, two moving platforms 200, two flipping assemblies 300, a driving member 400, a first transmission member 500, and a second transmission member 600.

The mobile platforms 200 move closer or farther away; the second transmission assembly 600 is transmission-connected between the driving shaft 410 and the two flip assemblies 300, and can drive the two flip assemblies 300 to flip around their respective flip axes; the flip assembly 300 has a picking surface 362 and a supporting surface 363 set at an angle. Before the flip assembly 300 is flipped, the flip assembly 300 supports the edge banding 2000 and the box top wall 1100 through the picking surface 362. After the flip assembly 300 is flipped, the flip assembly 300 supports the box top wall 1100 through the supporting surface 363, and the edge banding 2000 is sandwiched between the box side wall 1200 and the flip assembly 300.

[0059] When in use, the edge strip 2000 is placed on the flip assembly 300, and then the box cover 1000 is buckled on the flip assembly 300. After starting the driving member 400, the flip assembly 300 is flipped and the edge strip 2000 is attached to the inner side of the box side wall 1200 of the box cover 1000. The whole process is efficient and saves manpower. At the same time, the box cover 1000 is buckled on the flip assembly 300 during the attachment process. After being attached, the edge strip 2000 naturally droops without bending, avoiding creases. When attached to the box body, it is beneficial to ensure flatness and improve the use effect.

[0060] Combination Figure 1 and 3As shown, in order to achieve the mutual approach or distance between the two mobile platforms 200, in some embodiments, the first transmission member 500 includes a first cam, the first cam has a mounting hole matched with the driving shaft 410, the first cam is provided with a first annular groove 510 in a rhombus shape and surrounding the outer periphery of the mounting hole, the mobile platform 200 is provided with a first sliding pin 210, the first sliding pin 210 is partially located in the first annular groove 510, and can slide along the first annular groove 510, the driving member 400 can drive the first cam to rotate, and drive the two mobile platforms 200 to approach or move away from each other. Through the cooperation of the first sliding pin 210 and the first annular groove 510, the moving path of the first sliding pin 210 can be effectively constrained, so that the two first sliding pins 210 can be driven to move away from each other from the inner side wall by relying on the first annular groove 510, and the two first sliding pins 210 can be driven to approach each other by relying on the outer side wall of the first annular groove 510, thereby driving the two mobile platforms 200 to approach or move away from each other. In addition, the first annular groove 510 is an annular structure and a central symmetrical structure, so that the driving shaft 410 can rotate in the same direction during the working process, and the control is simpler. Among them, the driving shaft 410 rotates 180 degrees, and the two mobile platforms 200 realize a cycle of approaching and moving away, that is, the driving shaft 410 rotates 180 degrees, so that the two mobile platforms 200 first approach each other and then move away from each other.

[0061] To achieve the flipping of the flip assembly 300, in some embodiments, the second transmission assembly 600 includes a second cam 610 and a lifting member 620, the lifting member 620 is movably arranged on the frame 100 along the third direction, the second cam 610 is connected between the driving shaft 410 and the lifting member 620, and drives the lifting member 620 to reciprocate along the third direction during the rotation process, the lifting member 620 is connected to the flip assembly 300, and can drive the flip assembly 300 to flip during the lifting process. Specifically, in combination with Figures 4 to 6 As shown, the second cam 610 has a mounting portion that cooperates with the driving shaft 410 and a second annular groove 611 surrounding the outer circumference of the mounting portion; the lifting member 620 is provided with a second sliding pin 6211, and a portion of the second sliding pin 6211 is located in the second annular groove 611 and can slide along the second annular groove 611.

Figure 5As shown, the second annular groove 611 is in the shape of a runway, and includes two short track portions 613 and two long track portions 612. The length of the short track portion 613 is smaller than that of the long track portion 612. The second cam 610 is in the shape of a long strip. The two short track portions 613 are arranged at both ends of the length direction of the second cam 610. The two long track portions 612 are located between the two short track portions 613, and form a ring-shaped second annular groove 611. When the second sliding pin 6211 moves from the short track portion 613 to the long track portion 612, the lifting member 620 descends, and when the second sliding pin 6211 moves from the long track portion 612 to the short track portion 613, the lifting member 620 rises. In order to achieve smooth sliding, the two long track portions 612 are recessed in a direction close to each other, so that the long track portion 612 and the short track portion 613 can smoothly transition; at the same time, the distance between the recessed part of the long track portion 612 and the mounting portion is smaller, which can make the lifting range of the lifting member 620 larger. In some embodiments, the second cam 610 and the driving shaft 410 are integrally formed. The first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0062] In addition, the second annular groove 611 is an annular structure and a central symmetrical structure, which can make the driving shaft 410 rotate in the same direction during operation, making the control easier. When the driving shaft 410 rotates 180°, the two flipping assemblies 300 complete a flipping cycle.

[0063] In this embodiment, the same driving shaft 410 drives two cams, which saves power source and reduces production and use costs. To ensure the smoothness and force balance of the driving shaft 410, the driving shaft 410 is provided with two bearings spaced apart along the axis of the driving shaft 410, and the outer ring of the bearing is connected to the frame 100.

[0064] The lifting member 620 includes a lifting seat 621 and a lifting adjustment block 622. The lifting seat 621 is slidably disposed on the frame 100 along the third direction.

The fixing screw is partially located in the elongated hole and partially engaged with the fixing screw hole thread.

[0065] In some embodiments, the flip assembly 300 includes a flip base 310 and a flip mechanism. The flip base 310 is disposed on the mobile platform 200 and moves synchronously with the mobile platform 200. The flip mechanism rotates with the flip base 310 through a flip shaft 321. The axis of the flip shaft 321 forms a flip axis. The flip sliding pin 322 is disposed on the flip mechanism. The flip base 310 and the flip mechanism are separately disposed, which is convenient for processing, improves processing efficiency, and is convenient for separate adjustment to adapt to different application scenarios.

[0066] Combination Figure 4 As shown, in order to constrain the extreme position of the flip mechanism, in some embodiments, the flip mechanism can rotate between the initial position before flipping and the attached position after flipping; wherein, the flip assembly 300 also includes a limiter 311, the limiter 311 is arranged on the flip base 310, and the flip mechanism at the attached position abuts against the limiter 311. The above arrangement can perform hard limit on the flip mechanism to prevent the flip mechanism from damaging the box cover 1000 during the rotation process. The flip assembly 300 also includes a sensor 312, the sensor 312 is arranged on the flip base 310, and the flip mechanism at the attached position abuts against the sensor 312. wherein, after the flip mechanism contacts the sensor 312, the controller controls the flip mechanism to stop rotating.

Among them, at least a part of the floating member 340 forms a partial pick-up surface 362. The provision of the elastic member 330 ensures that when the edge banding strip 2000 is attached to the box side wall 1200, the pressure is an elastic force, thereby preventing the box side wall 1200 from being damaged.

[0068] In order to regulate and constrain the running trajectory of the floating member 340 relative to the flip bracket 320, in some embodiments, the flip mechanism also includes a guide member 350, which is arranged between the floating member 340 and the flip bracket 320, and the floating member 340 can approach or move away from the flip bracket 320 along the guide member 350.

[0069] Specifically, the guide member 350 includes a screw, the flip bracket 320 is provided with a guide channel, the floating member 340 is provided with a floating screw hole, the screw is partially located in the guide channel, and partially screwed in the floating screw hole, the screw nut is located on the side of the flip bracket 320 away from the floating member 340, and the outer diameter of the nut is greater than the diameter of the guide channel. With the cooperation of the screw and the guide channel, the floating member 340 moves relative to the flip bracket 320 along the axial direction of the screw to avoid offset, thereby ensuring the alignment accuracy of the edge banding 2000 and the box side wall 1200; at the same time, the maximum distance between the floating member 340 and the flip bracket 320 can be adjusted by screwing the screw, thereby adjusting elastic forces of different sizes.

[0070] In some embodiments, the elastic member 330 is a spring, which is sleeved on the outer periphery of the screw, and one end of the spring abuts against the floating member 340, and the other end abuts against the flip bracket 320. The above arrangement improves the stability of the elastic member 330 and avoids misalignment.

Specifically, there are four screws and four springs, and the four springs are respectively sleeved on the corresponding four screws.

[0072] Combination Figure 4 As shown, considering that the edge banding strip 2000 needs to rotate with the flipping mechanism, in order to avoid falling during the flipping process, in some embodiments, the flipping mechanism also includes an adsorption member 360, which is arranged on the floating member 340 and is used to adsorb the edge banding strip 2000; before the flipping assembly 300 is flipped, the side of the adsorption member 360 away from the flipping bracket 320 forms a local pickup surface 362, and the opposite surfaces of the two adsorption members 360 form a support surface 363; the adsorption member 360 is provided with an adsorption hole 361 that passes through the pickup surface 362, and the floating member 340 is provided with an adsorption channel, the adsorption hole 361 is connected to the adsorption channel, and the adsorption channel is connected to an external vacuum air source. This arrangement allows the edge banding strip 2000 to flip from a horizontal state to a vertical state, and will not be misaligned or separated from the pickup surface 362, thereby ensuring the accuracy of the attachment position of the edge banding strip 2000.

[0073] In order to ensure the docking accuracy between the edge strip 2000 and the box side wall 1200, it is necessary to ensure the docking accuracy between the edge strip 2000 and the floating member 340. For this purpose, a positioning column 341 is provided on the floating member 340, and the positioning column 341 is used to be plugged into and matched with the positioning hole on the edge strip 2000.

[0074] Due to the flipping process of the flipping mechanism, the pick-up surface 362 supporting the top wall 1100 of the box is gradually transformed into the support surface 363, and the suction piece 360 ​​has sliding friction with the top wall 1100 of the box. To avoid scratches, in some embodiments, before flipping, the tops of the two opposite surfaces of the two suction pieces 360 are rounded. In other words, the pick-up surface 362 and the support surface 363 are connected by an arc surface transition, so that the suction piece 360 ​​and the top wall 1100 can slide smoothly during the flipping process, avoiding scratches on the top wall 1100. The suction piece 360 ​​is a plate-like structure and is made of rubber, with a certain buffering performance, so as to avoid scratches on the box cover 1000 and / or the edge strip 2000 when contacting the box side wall 1200 of the box cover 1000.

[0075] In this embodiment, the pick-up surface 362 and the support surface 363 form an angle of 90 degrees, that is, the flip mechanism needs to rotate 90 degrees around the flip axis when it rotates from the initial position to the attachment position. This arrangement allows the flip mechanism to be in the initial position, and the pick-up surface 362 can carry the horizontally placed edge strip 2000. When the flip mechanism is in the attachment position, the edge strip 2000 is arranged vertically and parallel to the box side wall 1200 to avoid bending.

[0076] To adjust the initial position of the flip mechanism, before the flip assembly 300 flips, in order to make the picking surface 362 parallel to the horizontal plane, in some embodiments, the flip assembly 300 further includes an adjusting screw 370, and the flip base 310 and the mobile platform 200 are adjustable in position along the third direction. The mobile platform 200 is provided with an adjusting screw hole, and the adjusting screw 370 part is threadedly matched with the adjusting screw hole, and the end away from the nut is used to abut the mobile platform 200. This arrangement makes the height of the flip base 310 relative to the mobile platform 200 adjustable, so that the height of the second sliding pin 6211 relative to the mobile platform 200 is adjustable under the premise that the position of the lifting member 620 remains unchanged, so that the angle of the picking surface 362 relative to the horizontal plane is adjustable.

[0077] Regarding the connection between the flip base 310 and the mobile platform 200, in some embodiments, the flip base 310 is provided with an adjustment long hole 313 extending along the third direction, and the mobile platform 200 is provided with a fastening screw hole, and the fastening screw passes through the adjustment long hole 313 and is screwed into the fastening screw hole.

[0078] This embodiment further provides a material pasting method, which is applied to the material pasting device for the inner side wall of a box-shaped workpiece in any of the above embodiments. The material pasting method comprises the following steps:

[0079] The two edge banding strips 2000 are placed on the two flipping assemblies 300 respectively.

[0080] The box cover 1000 is placed upside down on the two flip assemblies 300 , and the box top wall 1100 is pressed onto the two edge bands 2000 .

[0081] The driving member 400 is actuated, and the two moving platforms 200 move away from each other. Meanwhile, the two flipping assemblies 300 are flipped to attach the two edge banding strips 2000 to the inner sides of the two box side walls 1200 of the box cover 1000 .

[0082] With the help of the above method, the attachment process of the edge strip 2000 is efficient and saves manpower; at the same time, the box cover 1000 is buckled on the flip assembly 300 during the attachment process, and the edge strip 2000 naturally droops after being attached, and will not bend, avoiding creases. When attached to the box body, it is beneficial to ensure flatness and improve the use effect.

[0083] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
