Description

Technical Field

[0001] The present invention relates to the technical field of assembly, in particular to a BIM assembly line. Background Art

[0002] Adhesive backing has a series of characteristics such as easy use, easy bending, ultra-thin volume, reliable performance, etc., and is widely used in electronic products such as PDP TVs, LCD monitors, LCD TVs, mobile phones, laptops, MP3s, communication cabinets, medical instruments, as well as military and aerospace fields. The adhesive backing is usually attached manually, which consumes a lot of labor, and the adhesive backing needs to be manually aligned during attachment. A slight tilt or misalignment will cause the product to be scrapped, and the defective rate is high. In addition, a slight error in the attachment process will introduce bubbles, causing the product to be scrapped, wasting raw material resources, and at the same time, increasing the adhesive attachment cost.

[0003] In the Chinese patent with the Chinese patent publication number "CN103395508B", an invention patent named "Glue Sticking Jig" is disclosed, and its technical solution is as follows: it includes a base and a movable plate group, the base has a bottom plate and at least one first side plate connected to the bottom plate, the first side plate has a top surface and a side surface adjacent to the top surface, and the movable plate group can move toward the bottom plate. The movable plate group includes a tape bearing plate and a panel bearing plate, and the tape bearing plate and the panel bearing plate are located on the inner side of the base. When in use, the tape bearing plate and the first side plate can first carry the tape together. Then, the panel can be pressed down, and when the panel drops to the inner side of the base, part of the tape can be bent between the first side plate and the panel and pressed against the side of the panel. Although the present invention allows workers to easily apply glue and reduces the time required for turning over the panel, the workers only need to press down the panel to attach the tape to the side of the panel, saving the trouble of manually bending the tape to attach the tape to the side of the panel. However, the jig of the invention still requires manual glue pressing to complete the gluing process, and does not completely replace manual glue application. Therefore, there is still the problem that a slight error in the attachment process will introduce bubbles, resulting in product scrapping, wasting raw material resources, and at the same time increasing the cost of gluing.

[0004] In the Chinese patent with the Chinese patent publication number of "CN103244528A", an invention patent named "manual glue sticking jig" is disclosed, and its technical scheme is as follows: it includes: a base, a tape hanger, a support seat and a pressing sheet, the tape hanger is arranged at one end of the base, the support seat is placed at the other end of the base, a foam positioning groove is arranged in the middle of the base, the tape hanger and the support seat are both symmetrically centered on the foam positioning groove, the pressing sheet is arranged parallel to the foam positioning groove, and one end of the pressing sheet is fixed on the support seat, and the other end extends to the outer surface of the foam positioning groove. Through the above-mentioned method, the manual glue sticking jig of the present invention has a simple structure, is easy to operate, can reduce labor, improve production efficiency, has a good positioning effect, and has a high glue sticking yield. However, the present invention does not solve the problem of bubbling when the tape is attached to the foam, and there is a problem that the tape and the foam are not tightly attached. In addition, if the glue sticking quality is guaranteed by the pressing sheet alone, there is a problem of discontinuity at the sticking point, which affects the glue sticking quality.

The top of the frame 3 is located at the feeding end of the conveying mechanism 2 and an iron shell feeding mechanism is fixedly installed. The top of the frame 3 is located at the rear side of the gantry 6 and a back-adhesive feeding mechanism is fixedly installed. A fixing frame 10 is fixedly installed on the front side wall of the top of the frame 3. A positioning camera 9 is fixedly installed on the fixing frame 10. The positioning camera 9 is located directly above the conveying mechanism 2. The positioning camera 9 is used to locate the position of the iron shell on the conveying mechanism 2. Film tearing mechanisms are fixedly installed on the inner walls on both sides of the frame 3. The film tearing mechanisms are located directly below the gantry 6.

[0018] In some embodiments, when the product needs to be assembled with adhesive backing, the iron shell is preferentially placed on the iron shell feeding mechanism, and the adhesive backing is placed in the adhesive backing feeding mechanism, and the iron shell feeding mechanism is driven, so that the iron shell product on the iron shell feeding mechanism is placed on the conveying mechanism 2. At this time, the iron shell product on the conveying mechanism 2 is photographed and positioned by the positioning camera 9. At this time, the assembly mechanism 1 extends into the adhesive backing feeding mechanism. At this time, the assembly mechanism 1 absorbs the adhesive backing in the adhesive backing feeding mechanism and moves with the adhesive backing to the top of the film tearing mechanism. At this time, the film tearing mechanism is in contact with the adhesive backing and tears the adhesive backing. After the film tearing is completed, it moves to the top of the iron shell product after the photographing and positioning is completed. At this time, the assembly mechanism 1 carries the adhesive backing to fit the iron shell product and presses down longitudinally, so that the adhesive backing is pressed against the iron shell product.

The bottom of the first slide rail 20 is sequentially installed with first chains 21 for controlling the sliding of the three groups of transport platforms 22.

[0022] The iron shell feeding mechanism is driven to cause the iron shell to move laterally. At this time, the conveying platform 22 located below the iron shell feeding mechanism is driven by the first chain 21 until the iron shell falls on the conveying platform 22. The conveying platform 22 follows the lateral movement, so that the iron shell is placed completely horizontally on the conveying platform 22.

[0023] The iron shell feeding mechanism includes a mounting plate 12, a first motor 13, a conveying roller 11, a fixed plate 14, a first gear 15 and a second gear 16.

Several groups of equally spaced conveying rollers 11 are rotatably installed on the corresponding side walls of the mounting plate 12. The bottom of the conveying roller 11 is horizontally arranged with the top of the conveying mechanism 2. The rotating shaft of the conveying roller 11 transversely penetrates the mounting plate 12 and extends to the outside of the mounting plate 12. The conveying roller 11 is located at one end of the outer side of the mounting plate 12 and is fixedly installed with a second gear 16. The outer side wall of the mounting plate 12 is fixedly installed with a fixed plate 14. The corresponding side wall of the fixed plate 14 is rotatably installed with a first gear 15.

[0024] The first motor 13 drives the first gear 15 to rotate. At this time, since the first gear 15 is meshed with the second gear 16, the second gear 16 and the conveying roller 11 rotate, thereby conveying the iron shell.

[0026] When the iron shell is conveyed to the discharge end by the conveying roller 11 , the first electric push rod 18 is driven to cause the two sets of push plates 17 to move toward each other, thereby centering the iron shell on the conveying roller 11 .

[0027] The adhesive feeding mechanism includes a positioning plate 26, a fixed rod 25 is fixed on the top of the positioning plate 26, the number of the fixed rods 25 is four groups and they are arranged in a rectangular array, an adsorption platform 24 is fixedly installed on the top of the fixed rod 25, a plurality of groups of vacuum adsorption holes are provided on the adsorption platform 24 and are arranged equidistantly, a first guide rod 28 is fixedly installed on the top of the positioning plate 26 on one side of the adsorption platform 24, a adhesive platform 30 is sleeved on the first guide rod 28, the adhesive platform 30 is slidably connected to the first guide rod 28, a plurality of groups of movable openings 23 are provided on the outer wall of the adhesive platform 30, an adjusting rod 29 is slidably installed on the top of the positioning plate 26, the adjusting rod 29 is located in the movable opening 23 and is slidably connected to the movable opening 23, a second electric push rod 27 is fixedly installed on the bottom of the positioning plate 26, the telescopic end of the second electric push rod 27 longitudinally penetrates the positioning plate 26 and is fixedly connected to the adhesive platform 30.

[0028] When the user places the adhesive on the adhesive platform 30, each group of adjustment rods 29 moves in the movable opening 23, so that the adjustment rods 29 can position the adhesive. At this time, when the adhesive is continuously taken out by the robot arm 7, the second electric push rod 27 drives the adhesive platform 30 to move longitudinally, so that the adhesive at the bottom of the adhesive platform 30 can move to the optimal material taking position of the robot arm 7.

[0029] The film tearing mechanism includes a second slide rail 35, which is fixedly connected to the frame 3, and a mounting platform 34 is slidably installed on the second slide rail 35. There are two groups of mounting platforms 34, which are sequentially located at both ends of the second slide rail 35. A protective plate 37 is fixedly installed at the bottom of the second slide rail 35, and the protective plate 37 is arranged in an L-shaped structure.

A second connecting plate 36 is fixedly installed on the top of the mounting platform 34, and the second connecting plate 36 is arranged in an L-shaped structure. An electric claw clamp 31 is installed on the top of the second connecting plate 36.

[0030] When the robot arm 7 moves the back glue to above the film tearing mechanism, the back glue is horizontally arranged with the second slide rail 35, and at the same time, the robot arm 7 carries the back glue and fits it with the electric claw clamp 31. At this time, the electric claw clamp 31 clamps the protective film on the back glue. At this time, the robot arm 7 carries the back glue and moves, cooperating with the protective film clamped by the electric claw clamp 31, so as to tear the protective film.

[0031] Working principle: In some embodiments, when the product needs to be assembled with adhesive, the iron shell is preferentially placed on the iron shell feeding mechanism, and the adhesive is placed in the adhesive feeding mechanism at the same time, and the iron shell feeding mechanism is driven, so that the iron shell product on the iron shell feeding mechanism is placed on the conveying mechanism 2. At this time, the iron shell product on the conveying mechanism 2 is photographed and positioned by the positioning camera 9, and the assembly mechanism 1 extends into the adhesive feeding mechanism. At this time, the assembly mechanism 1 absorbs the adhesive in the adhesive feeding mechanism and moves with the adhesive to the top of the film tearing mechanism. At this time, the film tearing mechanism is in contact with the adhesive and the adhesive is torn off. After the film tearing is completed, it moves to the top of the iron shell product after the photographing and positioning is completed. At this time, the assembly mechanism 1 carries the adhesive to fit the iron shell product and presses down longitudinally, so that the adhesive is pressed against the iron shell product; When it is necessary to operate, the driving motor in the machine base 5 is driven to cause the mechanical arm 7 to rotate until the mechanical arm 7 moves to the adhesive feeding mechanism. At this time, the suction cup plate 8 is in contact with the adhesive in the adhesive feeding mechanism. At this time, the vacuum suction cup in the suction cup plate 8 absorbs the adhesive, and the mechanical arm 7 continues to drive and moves to the top of the film tearing mechanism, waiting for the film tearing mechanism to perform the film tearing operation; The iron shell feeding mechanism is driven to cause the iron shell to move laterally. At this time, the transport platform 22 located below the iron shell feeding mechanism is driven by the first chain 21 until the iron shell falls on the transport platform 22. The transport platform 22 follows the lateral movement, so that the iron shell is completely horizontally placed on the transport platform 22. At this time, when the transport platform 22 moves below the positioning camera 9, the positioning camera 9 can take a picture of the iron shell on the transport platform 22 and wait for the adhesive to be pressed; The first motor 13 drives the first gear 15 to rotate. At this time, the first gear 15 is meshed with the second gear 16, causing the second gear 16 and the conveying roller 11 to rotate, thereby conveying the iron shell. When the iron shell is conveyed to the discharge end by the conveying roller 11, the first electric push rod 18 is driven to cause the two sets of push plates 17 to move toward each other, thereby centering the iron shell on the conveying roller 11. When the user places the adhesive on the adhesive platform 30, each group of adjustment rods 29 is located in the movable opening 23 and moves, so that the adjustment rods 29 can position the adhesive. At this time, when the adhesive is continuously taken out by the robot arm 7, the second electric push rod 27 drives the adhesive platform 30 to move longitudinally, so that the bottom adhesive of the adhesive platform 30 can move to the optimal material picking position of the robot arm 7. When the robot arm 7 moves the adhesive to above the film tearing mechanism, the adhesive is horizontally arranged with the second slide rail 35, and at the same time, the robot arm 7 carries the adhesive and fits with the electric claw clamp 31. At this time, the electric claw clamp 31 clamps the protective film on the adhesive. At this time, the robot arm 7 carries the adhesive to move and cooperates with the protective film clamped by the electric claw clamp 31, so as to tear the protective film.
