Description

Technical Field

[0001] The present invention relates to the technical field of automatic assembly, and in particular to a device for attaching materials to the inner wall of a box-shaped workpiece. Background Art

[0002] A packaging box is a box used to package products. It can ensure product safety and enhance product quality. It is widely used in various industries such as electronics, food, and cosmetics. Common packaging boxes include paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, and PVC boxes. Manufacturers choose the appropriate packaging box based on different products and needs. During manufacturing, after the product is placed in the box body, the box lid is placed on the box body, and edge banding is affixed between the lid and the box body to ensure the box is sealed and also play a certain anti-counterfeiting role.

[0003] For some product packaging boxes, the lid completely surrounds the side walls of the box body. To ensure the integrity of the lid's appearance, some manufacturers require affixing a portion of the edge banding to the inner wall of the lid. Once the lid and box body are assembled, the remaining portion is bent and affixed to the box body. Currently, edge banding is manually applied, and during this process, the lid opening must be facing upward. This can easily cause the edge banding to tip over or even bend, resulting in creases that affect the subsequent attachment to the box body. Furthermore, the entire process is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, it is urgent to study a device for attaching materials to the inner wall of a box-shaped workpiece to improve the use effect and increase the efficiency of attaching edge banding strips. Summary of the Invention

[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0050] 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.

[0051] The device for pasting the inner wall of a box-shaped workpiece includes a frame 100, two mobile platforms 200, two flip assemblies 300, a driving member 400, a first transmission member 500, and a second transmission member 600. The two mobile platforms 200 are arranged on the frame 100 at intervals along the first direction and can move closer to or farther away from each other; the two flip assemblies 300 are respectively arranged on the corresponding two mobile platforms 200 and can flip with the relative mobile platforms 200, and the flip axis extends along the second direction; the driving member 400 is arranged on the frame 100, and the driving member 400 synchronously drives the mobile platforms 200 and the flip assemblies 300, and the driving shaft 410 connected to the driving member 400 extends along the second direction and can rotate around its own axis; the first transmission member 500 is connected between the driving shaft 410 and the two mobile platforms 200, and can drive the two mobile platforms 200. The mobile platforms 200 move closer or further 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.

[0052] 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 part 400, the flip assembly 300 flips and attaches the edge strip 2000 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 conducive to ensuring flatness and improving the use effect.

[0053] Combine Figure 1 and 3As shown, to achieve the movement of the two mobile platforms 200 toward or away from each other, in some embodiments, the first transmission member 500 includes a first cam having a mounting hole that mates with the driving shaft 410. The first cam is provided with a first annular groove 510 in a diamond shape and surrounding the outer periphery of the mounting hole. The mobile platforms 200 are 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, thereby driving the two mobile platforms 200 toward or away from each other. The cooperation between the first sliding pin 210 and the first annular groove 510 effectively constrains the movement path of the first sliding pin 210, so that the two first sliding pins 210 can be driven away from each other by the inner side wall of the first annular groove 510, and the two first sliding pins 210 can be driven toward each other by the outer side wall of the first annular groove 510, thereby driving the two mobile platforms 200 toward or away from each other. Furthermore, the first annular groove 510 is an annular, centrally symmetrical structure, allowing the driving shaft 410 to rotate in the same direction during operation, simplifying control. Specifically, a 180° rotation of the driving shaft 410 causes the two mobile platforms 200 to move closer and further apart. Specifically, a 180° rotation of the driving shaft 410 causes the two mobile platforms 200 to first move closer and then further apart.

[0054] In order 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 provided 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 move back and forth along the third direction during the rotation process. The lifting member 620 is in transmission connection with 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 the second sliding pin 6211 is partially located in the second annular groove 611 and can slide along the second annular groove 611. The lifting member 620 is provided with a lifting groove 6221 extending along the first direction, and the flip assembly 300 has a flip sliding pin 322, which is located outside the flip axis, and the flip sliding pin 322 is partially located in the lifting groove 6221 and can slide along the lifting groove 6221. Figure 5As shown, the second annular groove 611 is shaped like a runway and comprises two short track portions 613 and two long track portions 612. The short track portions 613 are shorter than the long track portions 612. The second cam 610 is elongated, with the two short track portions 613 arranged at either end of the second cam 610 in its longitudinal direction. The two long track portions 612 are located between the two short track portions 613, forming a circular 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. When the second sliding pin 6211 moves from the long track portion 612 to the short track portion 613, the lifting member 620 ascends. To ensure smooth sliding, the two long track portions 612 are recessed toward each other, allowing for a smooth transition between the long track portion 612 and the short track portion 613. Furthermore, the recessed portion of the long track portion 612 is closer to the mounting portion, allowing the lifting member 620 to have a greater range of movement. 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.

[0055] In addition, the second annular groove 611 is an annular structure and a centrally symmetrical structure, which allows the driving shaft 410 to rotate in the same direction during operation, making control easier. Among them, the driving shaft 410 rotates 180 degrees, and the two flip assemblies 300 complete a flip cycle.

[0056] In this embodiment, the two cams are driven by a single drive shaft 410, which saves power and reduces production and operating costs. To ensure smooth rotation and balanced force distribution of the drive shaft 410, the drive shaft 410 is provided with two bearings spaced apart along the axis of the drive shaft 410. The outer rings of the bearings are connected to the frame 100.

[0057] The lifting member 620 includes a lifting seat 621 and a lifting adjustment block 622. The lifting seat 621 is slidably mounted on the frame 100 along the third direction. The lifting adjustment block 622 is adjustable along the third direction on the lifting seat 621. A lifting slot 6221 is provided on the lifting adjustment block 622. The lifting adjustment block 622 is provided with an elongated hole extending along the third direction. The lifting seat 621 is provided with a fixing screw hole. The fixing screw is partially located in the elongated hole and partially engages with the fixing screw hole.

[0058] In some embodiments, the flip assembly 300 includes a flip base 310 and a flip mechanism. The flip base 310 is mounted on the mobile platform 200 and moves synchronously with the mobile platform 200. The flip mechanism rotates with the flip base 310 via a flip shaft 321. The axis of the flip shaft 321 forms the flip axis. A flip sliding pin 322 is mounted on the flip mechanism. The flip base 310 and the flip mechanism are configured separately to facilitate processing, improve processing efficiency, and facilitate separate adjustment to suit different application scenarios.

[0059] Combine Figure 4 As shown, in order to constrain the extreme positions of the flip mechanism, in some embodiments, the flip mechanism can rotate between an initial position before flipping and an attached position after flipping; wherein, the flip assembly 300 also includes a limiter 311, which is provided on the flip base 310, and the flip mechanism in the attached position abuts the limiter 311. The above arrangement can provide a hard limit for the flip mechanism, preventing damage to the box cover 1000 during the flip mechanism rotation process. The flip assembly 300 also includes a sensor 312, which is provided on the flip base 310, and the flip mechanism in the attached position abuts the sensor 312. wherein, after the flip mechanism contacts the sensor 312, the controller controls the flip mechanism to stop rotating.

[0060] To reduce the required flipping angle accuracy of the flipping mechanism when attaching the edge banding 2000 to the box sidewall 1200, in some embodiments, the flipping mechanism includes a flip bracket 320, an elastic member 330, and a floating member 340. The flip bracket 320 rotatably engages with the flip base 310 via a flip shaft 321. A flip sliding pin 322 is disposed on the flip bracket 320, and the elastic member 330 is disposed between the floating member 340 and the flip bracket 320. At least a portion of the floating member 340 forms a partial pickup surface 362. The provision of the elastic member 330 ensures that when the edge banding 2000 is attached to the box sidewall 1200, the pressure is an elastic force, preventing damage to the box sidewall 1200.

[0061] 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.

[0062] Specifically, the guide member 350 includes a screw, the flip bracket 320 is provided with a guide channel, and the floating member 340 is provided with a floating screw hole. The screw is partially located in the guide channel and partially threaded into the floating screw hole. The screw cap is located on the side of the flip bracket 320 away from the floating member 340, and the outer diameter of the cap is larger than the diameter of the guide channel. The screw and the guide channel cooperate to allow the floating member 340 to move relative to the flip bracket 320 along the screw axis, preventing misalignment and ensuring accurate alignment between the edge banding 2000 and the box sidewall 1200. Furthermore, turning the screw adjusts the maximum distance between the floating member 340 and the flip bracket 320, thereby adjusting the elastic force to varying degrees.

[0063] In some embodiments, the elastic member 330 is a spring, which is sleeved around the outer periphery of the screw, with one end abutting the floating member 340 and the other end abutting the flip bracket 320. The above arrangement improves the stability of the elastic member 330 and avoids dislocation.

[0064] To improve the smoothness of movement and balanced force distribution of the floating member 340, at least three guide members 350 are provided, and the at least three guide members 350 are dispersed. At least three elastic members 330 are provided, and are dispersed between the flip bracket 320 and the floating member 340. Specifically, there are four screws and four springs, and the four springs are respectively mounted on the corresponding four screws.

[0065] Combine Figure 4 As shown, considering that the edge banding 2000 needs to rotate with the flipping mechanism, to prevent it from falling during the flipping process, in some embodiments, the flipping mechanism also includes a suction member 360, which is arranged on the floating member 340 and is used to absorb the edge banding 2000. Before the flip assembly 300 flips, the side of the suction member 360 away from the flip bracket 320 forms a local pickup surface 362, and the opposing surfaces of the two suction members 360 form a support surface 363. The suction member 360 is provided with a suction hole 361 that passes through the pickup surface 362, and the floating member 340 is provided with a suction channel. The suction hole 361 is connected to the suction channel, and the suction channel is connected to an external vacuum air source. This arrangement allows the edge banding 2000 to flip from a horizontal state to a vertical state without being misaligned or detached from the pickup surface 362, thereby ensuring the accuracy of the attachment position of the edge banding 2000.

[0066] 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 part 340. For this purpose, a positioning column 341 is provided on the floating part 340, and the positioning column 341 is used to be plugged into and matched with the positioning hole on the edge strip 2000.

[0067] Due to the flipping process of the flipping mechanism, the pick-up surface 362 supporting the top wall 1100 gradually transforms into the support surface 363, and the adsorbent 360 experiences sliding friction with the top wall 1100. To avoid scratches, in some embodiments, before flipping, the top corners of the two opposing surfaces of the two adsorbents 360 are rounded. In other words, the pick-up surface 362 and the support surface 363 are transitionally connected by an arc surface, so that the adsorbent 360 and the top wall 1100 can slide smoothly during the flipping process, avoiding scratches on the top wall 1100. The adsorbent 360 is a plate-shaped structure made of rubber with a certain cushioning performance to avoid scratches on the box cover 1000 and / or the edge banding 2000 when in contact with the box side wall 1200 of the box cover 1000.

[0068] In this embodiment, the pick-up surface 362 and the support surface 363 form a 90-degree angle, meaning that the flip mechanism must rotate 90 degrees about the flip axis to move from the initial position to the attachment position. This arrangement allows the flip mechanism to support a horizontally placed edge strip 2000 on the pick-up surface 362 when in the initial position. When the flip mechanism is in the attachment position, the edge strip 2000 is arranged vertically and parallel to the box sidewall 1200, preventing bending.

[0069] To adjust the initial position of the flip mechanism, and to make the picking surface 362 parallel to the horizontal plane before the flip assembly 300 flips, in some embodiments, the flip assembly 300 further includes an adjustment screw 370. The flip base 310 and the mobile platform 200 are positionally adjustable along the third direction. The mobile platform 200 is provided with an adjustment screw hole.
