Description

Technical Field

[0001] The utility model relates to a 27-inch foam tape attaching device, belonging to the technical field of display manufacturing. Background Art

[0002] During display production, foam tape needs to be applied to the surface of the plastic frame. The foam tape consists of a foam layer, a double-sided adhesive layer, and a release film layer. When applying it to the plastic frame, the foam tape and release film layer are first removed, and then the tape is manually aligned and adhered to the display's plastic frame. Currently, with the continuous development of the module industry, the size of displays is also constantly expanding, which has led to an increase in the difficulty of manual attachment. Because the length of the 27-inch tape is longer than that of ordinary products, there is a high possibility that the tape will touch other components during the attachment process, making attachment more difficult. The long tape is also difficult to fix. Moreover, the four foam tapes on the plastic frame are attached one by one, which makes it difficult to ensure the consistency of the attachment. The foam tape attachment accuracy is low, resulting in a gradually increasing defect rate. Summary of the Invention

[0003] The purpose of the utility model is to provide a 27-inch foam tape attaching device to solve the technical defect of poor attaching accuracy of the foam tape on the adhesive frame in the prior art.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a 27-inch foam tape attaching device, including a base and a baffle, the upper surface of the base is provided with two transverse groove units and two longitudinal groove units, the two ends of the two transverse groove units are respectively connected to the two ends of the two longitudinal groove units, and form a groove corresponding to the rectangular shape of the rubber frame to be attached with the foam tape, the number of baffles is eight, and a baffle is provided on both sides of the transverse groove unit and the longitudinal groove unit, and the baffle is slidably mounted on the base, and the baffle can be driven by a cylinder installed on the base to slide toward or away from the groove. The present invention has a groove on the base, and when in use, the foam tape is first placed in the groove, and the foam tape is accurately positioned by the groove, and then the rubber frame is placed in the groove so that the foam tape in the groove is attached to the rubber frame. Since the shape of the groove matches the shape of the rubber frame, the foam tape is accurately positioned, so the present invention can make the foam tape accurately attached to the rubber frame. Since the present invention is provided with a baffle, it is more convenient to place the rubber frame in the groove.

[0005] As a further improvement to the present invention, each baffle is slidably mounted on the upper surface of the base using two parallel rails. The rails below the baffles on either side of the transverse groove unit are perpendicular to the transverse groove, while the rails below the baffles on either side of the longitudinal groove unit are perpendicular to the longitudinal groove. By providing the rails, the present invention allows the baffles to slide more smoothly on the base, and the baffles move in a straight line.

[0006] As a further improvement of the present invention, a guide groove is formed on the upper surface of the slide rail along its length, and a slider is fixed to the bottom of the baffle. The slider is arranged in the guide groove and can slide in the guide groove. The present invention enables the baffle to slide on the slide rail by cooperating with the slider on the baffle and the guide groove on the slide rail.

[0007] As a further improvement of the present invention, one or more guide blocks are provided on the baffles on both sides of the transverse groove unit and the longitudinal groove unit, and the guide blocks are provided with inclined surfaces on the sides facing the transverse groove unit and the longitudinal groove unit. The present invention provides guide blocks, and the rubber frame is sleeved on the guide blocks. The inclined surfaces on the guide blocks cause the rubber frame to slide downward and fall into the groove, thereby more accurately positioning the rubber frame.

[0008] As a further improvement of the present invention, the inclined surface of the guide block facing the transverse groove unit and the longitudinal groove unit is bulged toward the groove to form an arc surface. The inclined surface in the present invention is an arc surface, which can make the plastic frame slide down into the groove more slowly.

[0009] As a further improvement to the present invention, multiple vacuum holes are provided at the bottom of both the transverse and longitudinal groove units. These holes, when in use, connect to a vacuum pump for adsorbing the foam tape placed within the grooves. By providing vacuum holes within the grooves, the present invention secures the foam tape after it is placed within the grooves, further improving the precision with which the foam tape adheres to the frame.

[0010] As a further improvement of the present invention, a valve is installed on the base, the vacuum adsorption hole is connected to the valve, and the valve is connected to the vacuum device via an air pipe when in use. The present invention controls the vacuum adsorption hole to adsorb the foam tape by setting the valve.

[0011] As a further improvement of the present invention, a stopper is further provided on each side of the longitudinal groove unit and the transverse groove unit, for limiting the movement of the baffle. The present invention blocks the sliding of the baffle by providing the stopper, thereby preventing the baffle from falling off the slide rail.

[0012] As a further improvement of the present invention, the length of the baffle between two transverse groove units is shorter than the length of the two opposite baffles, and both ends of the baffle between the two transverse groove units are provided with chamfers. The length of the baffle between two longitudinal groove units is shorter than the length of the two opposite baffles, and both ends of the baffle between the two longitudinal groove units are provided with chamfers. By providing chamfers at both ends of the baffles, the present invention can effectively prevent mutual interference between the baffles when they move.

[0013] To sum up, the beneficial effects of the present invention are as follows: the present invention adopts groove positioning and vacuum adsorption to fix the foam tape, which improves the consistency of tape attachment, reduces the rework rate, and thus increases production capacity. The present invention attaches 4 tapes at the same time, reduces the workload of employees, and thus improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 The 27-inch foam tape attaching device shown includes a base 1 and a baffle 2. The base 1 is a rectangular plate structure. Two transverse groove units 3 and two longitudinal groove units 4 are provided on the upper surface of the base 1. The two ends of the two transverse groove units 3 are respectively connected to the two ends of the two longitudinal groove units 4, and form a groove corresponding to the rectangular rubber frame shape to which the foam tape is to be attached. The width of the transverse groove unit 3 and the longitudinal groove unit 4 in the utility model is slightly larger than the width of the foam tape to facilitate placing the foam tape in the groove during use. The number of baffles 2 in the utility model is eight, and a baffle 2 is provided on each side of the transverse groove unit 3 and the longitudinal groove unit 4, and the baffle 2 is slidably installed on the base 1. The baffle 2 can be driven by a cylinder installed on the base 1 to slide toward or away from the groove.

[0021] In the present invention, each baffle 2 is slidably mounted on the upper surface of the base 1 using two parallel slide rails 5. The slide rails 5 in the present invention are fixed to the base 1, wherein the slide rails 5 below the baffle 2 on both sides of the transverse groove unit 3 are perpendicular to the transverse groove, and the slide rails 5 below the baffle 2 on both sides of the longitudinal groove unit 4 are perpendicular to the longitudinal groove. The present invention adopts bolts to detachably mount a slider with a rectangular cross section on the lower surface of the baffle 2, and a guide groove is opened on the upper surface of the slide rail 5 along the length direction of the slide rail 5. The slider is arranged in the guide groove and can slide in the guide groove. The groove cooperates with the slider on the baffle 2 so that the baffle 2 slides on the base 1. In the utility model, since each baffle 2 is installed with two slide rails 5, the sliding of the baffle 2 is smoother and slides in a straight line. The utility model is provided with a cylinder between the two slide rails 5 below each baffle 2 on the base 1. The piston rod of the cylinder is fixedly connected to the lower surface of the baffle 2, and the cylinder body of the cylinder is fixedly installed on the base 1. The piston rod of the cylinder is extended and retracted to drive the baffle 2 to slide on the base 1. The cylinders on both sides of the same horizontal groove unit 3 and the cylinders on both sides of the same longitudinal groove unit 4 of the utility model extend or contract synchronously.

[0022] In order to facilitate the placement of the rubber frame to be attached with the foam tape in the use state, the utility model is provided with guide blocks 6 on the baffle 2 on both sides of the transverse groove unit 3 and the longitudinal groove unit 4, and at least two guide blocks 6 are provided on each baffle 2. The bottom of the guide block 6 is fixedly connected to the baffle 2, and the guide block 6 is set to a slope 7 on the side facing the transverse groove unit 3 and the longitudinal groove unit 4, that is, the opposite side of the guide blocks 6 on both sides of the same transverse groove unit 3 is set to the slope 7, and the opposite side of the guide blocks 6 on both sides of the same longitudinal groove unit 4 is also set to the slope 7. When the rubber frame is placed on the guide block 6, the rubber frame slides downward into the groove under the action of the slope 7, so that the foam tape adheres to the rubber frame. In the utility model, the slope 7 of the guide block 6 on the side facing the transverse groove unit 3 and the longitudinal groove unit 4 bulges toward the direction of the groove to form an arc surface.

[0023] The utility model is provided with a plurality of vacuum adsorption holes 8 at intervals along the length direction of the bottom of the transverse groove unit 3 and the longitudinal groove unit 4. The vacuum adsorption holes 8 are connected to the vacuum pumping device when in use, and are used to adsorb the foam tape placed in the groove. When the foam tape is placed in the groove, the vacuum adsorption holes 8 are evacuated by the vacuum pumping device to ensure that the foam tape is fixed in the groove. The utility model is provided with a valve 9 installed on the base 1. The vacuum adsorption holes 8 are connected to the valve 9, and the valve 9 is connected to the vacuum pumping device through an air pipe.

[0024] In order to limit the movement of the baffle 2, the utility model is provided with a stop block 10. The utility model is provided with at least one stop block 10 on both sides of the longitudinal groove unit 4 and the transverse groove unit 3 to limit the movement of the baffle 2. The utility model is provided with a stop block 10 on both sides of each longitudinal groove unit 4 and each transverse groove unit 3. When the baffle 2 slides in the direction away from the groove until it abuts against the stop block 10, the baffle 2 no longer continues to slide. Therefore, in the utility model, the baffle 2 moves toward the stop block 10 until it abuts against the stop block 10 and reaches its maximum sliding range.

[0025] In the present invention, the length of the baffle 2 located between the two transverse groove units 3 is smaller than the length of the two baffles 2 opposite thereto, and chamfers 11 are provided at both ends of the baffle 2 located between the two transverse groove units 3. The length of the baffle 2 located between the two longitudinal groove units 4 is smaller than the length of the two baffles 2 opposite thereto, and chamfers 11 are provided at both ends of the baffle 2 located between the two longitudinal groove units 4. In this way, when the baffles 2 in the present invention move toward the transverse groove units 3 and the longitudinal groove units 4, no mutual interference will occur between the baffles 2.

[0026] When the utility model is used, Figure 1 After the cam 2 is in the closed position, the cam 2 is rotated and the cam 2 is rotated, so that the cam 2 is rotated in a direction away from the groove. After that, the cam 2 is rotated and the cam 2 is rotated, the cam 2 is rotated and the cam 2 is rotated. After that, the cam 2 is rotated and the cam 2 is rotated, the cam 2 is rotated and the cam 2 is rotated.
