Description

Technical Field

[0001] The present invention relates to the technical field of TV backplane production equipment, in particular to a device for pasting rubber strips in a TV backplane groove and a method for pasting rubber strips. Background Art

[0002] The frame of a TV backplane is usually provided with narrow grooves with lateral openings, which are used for limiting during the installation with other TV structural parts. Usually, multiple short rubber strips need to be pasted in the grooves to play a role in buffering and shock absorption between the structural parts. However, due to the narrow groove opening and limited operable space, it is difficult to ensure reliable pasting manually, and it is difficult to accurately grasp the pasting position of the rubber strips. The pasting direction of the rubber strips in the groove is prone to deviation. To overcome the deviation of the rubber strip pasting, a double-end synchronous pasting method is also used. However, due to the difficulty in controlling the distance between the double-end pasting positions, problems such as wrinkles and uneven pasting will eventually occur, and repeated correction of pasting will affect the adhesiveness of the rubber strips, which leads to unstable quality of pasting rubber strips in the TV backplane groove.

[0027] The present invention will be further described in detail below with reference to the drawings.

[0028] As shown in the attached Figures 1-4The described device for pasting rubber strips in the groove of a TV backplane and its method for pasting rubber strips include a device body 1. One end of the device body 1 is an insertion end, and the insertion end includes a first limiting module 2 and a second limiting module 3. The first limiting module 2 and the second limiting module 3 are arranged at an interval along the groove direction of the pasting groove 4. A clamping groove 21 is provided on the end face of the first limiting module 2 close to the bonding groove surface 41. When the rubber strip 5 is clamped into the clamping groove 21, the non-adhesive surface of the rubber strip 5 fits with the bottom of the clamping groove 21. The second limiting module 3 is a roller structure, and an annular groove 31 is provided on the outer circumferential surface of the second limiting module 3. When the rubber strip 5 is clamped into the annular groove 31, the adhesive surface of the rubber strip 5 fits with the bottom of the annular groove 31. It further includes a guiding mechanism 6. When the guiding mechanism 6 fits with the groove opening of the pasting groove 4, the rubber strip 5 clamped into the clamping groove 21 and the annular groove 31 at the same time is parallel to the groove direction of the pasting groove 4. Among them, the groove widths of the clamping groove 21 and the annular groove 31 are slightly larger than the width of the rubber strip, which plays a role of limiting and fixing while reducing the resistance during sliding pasting.

[0029] The first limiting module 2 and the second limiting module 3 are used to respectively fix two positions in the length direction of the rubber strip 5 by clamping. Also, since the two limiting ends are aligned and arranged at an interval along the groove direction of the pasting groove 4, the straightening direction of the rubber strip 5 between the two limiting clamping points is restricted. When pasting the rubber strip, the position relationship between the rubber strip and the pasting groove is determined by fitting the guiding mechanism with the groove opening of the pasting groove, and then the device body is slid along the groove direction to complete the pasting of the rubber strip. During the sliding process, the cooperation relationship between the guiding mechanism and the groove opening of the pasting groove is maintained to ensure that the straightening direction of the restricted section of the rubber strip 5 is always parallel to the pasting groove, avoiding the deviation of the pasting direction. In addition, the first limiting module can play a role of pressing and smoothing during the sliding pasting process to ensure that the pasted part is firmly and smoothly pasted. The second limiting module, by adopting a roller structure, can reduce the contact area with the adhesive surface of the rubber strip. And under the combined action of the overall sliding movement of the device and the adhesive force of the rubber strip, the second limiting module of the roller structure is prone to rotate. Thus, under the dual action of the small contact surface and rolling contact, the adhesion strength between the rubber strip and the second limiting module is extremely weak and it is very easy to separate, avoiding generating a large resistance to the sliding pasting action, making the rubber strip pasting more convenient and smooth, and having a small impact on the adhesiveness of the adhesive surface of the rubber strip, maintaining its good adhesiveness, and ensuring good stability between the rubber strip and the groove surface after pasting.

[0030] When the insertion end extends into the glue - pasting groove 4, the first limiting module 2 presses the rubber strip 4 to fit with the bonding groove surface 41, and the second limiting module 3 rolls the rubber strip 4 to fit with the opposite groove surface of the bonding groove surface 41. While pressing the rubber strip to bond with one side groove wall through the first limiting module 2, the second limiting module 3 rolls the non - pasted part of the rubber strip 3 to fit with the other side groove wall, so as to apply two opposite forces along the groove width direction at two points on the rubber strip, making the rubber strip between the two force - receiving points always keep a straight state, avoiding wrinkles in the rubber strip pasting. The rolling action of the second limiting module 3 can continuously straighten and flatten the non - pasted part of the rubber strip, and avoid the slip friction between the sticky surface of the rubber strip and the contact surface of the second limiting module 3, ensuring the pasting quality of the colloid.

[0031] The first limiting module 2 is fixedly connected to the first movable plate 7, the second limiting module 3 rotates around a short axis, the short axis is fixedly connected to the second movable plate 8, the first movable plate 7 and the second movable plate 8 are parallel to each other. When the insertion end extends into the glue - pasting groove 4, the length directions of the first movable plate 7 and the second movable plate 8 are parallel to the groove direction of the glue - pasting groove 4, and the first movable plate 7 and the second movable plate 8 are driven to move relatively closer or relatively farther away through an adjusting mechanism 9. By respectively installing the first limiting module and the second limiting module on two movable plates with adjustable spacing, it is used to make the distance between the two limiting modules adjustable in the groove width direction, so that when the insertion end of the rubber - strip pasting device is inserted into grooves with different groove widths, it can simultaneously play the roles of pressing and rolling, making its applicability more extensive.

[0032] An elastic reset structure 10 is clamped between the first movable plate 7 and the second movable plate 8. The elastic reset structure can adopt a spring structure connected between the two movable plates. When the distance between the first movable plate 7 and the second movable plate is reduced by adjustment, the elastic reset structure is compressed. When the insertion end is inserted into the corresponding glue - pasting groove, the force generated by the elastic reset structure restoring its original state can provide a pressure source for the pressing of the first limiting module and the rolling of the second limiting module. If the rubber - strip pasting device is manually operated, for example, the insertion end is arranged at the end of a handle. At this time, due to the double - groove - surface supporting effect of the first limiting module and the second limiting module, and the bidirectional pressure - applying effect of the elastic reset structure in the groove width direction, when the operator performs manual rubber - strip pasting, there is no need to deliberately apply a force tending to the glue - pasting groove surface side, and only need to press tightly to ensure that the guiding mechanism fits with the groove opening and then apply a force to drive the rubber - strip pasting device to slide along the groove direction.

[0033] On this basis, the adjusting mechanism 9 can adopt a pliers handle structure, which is composed of two cranks swinging around the same rotating shaft. The second movable plate 8 is fixedly connected to the end of one crank, while the first movable plate 7 is hinged to the end of the other crank. During use, by gripping the holding ends of the two cranks, the two cranks are relatively close to each other, thereby driving the two movable plates to approach each other, achieving the effect of adjusting and reducing the distance between the two limiting modules in the groove width direction. After inserting into the groove, then slowly release the gripping force to make the two limiting modules at the insertion end fit with the two side groove surfaces of the adhesive application groove respectively. The second movable plate 8 adopts a fixed connection method, and the first movable plate 7 adopts a hinge connection method, which is more conducive to positioning the adhesive tape pasting position during operation. During operation, first, press the crank fixedly connected to the second movable plate with the palm to control the second limiting module to press the non-adhesive surface of the adhesive tape to fit with the groove surface. Then, slowly release the four fingers of the grip, allowing the hinged crank to rotate relative to the fixed crank, so that the first movable plate 8 moves away from the second movable plate 7, and finally makes the adhesive surface of the adhesive tape stably contact the adhesive application groove surface, avoiding the adhesive tape from sticking to the groove surface when the position of the adhesive tape is not yet positioned, and improving the pasting quality.

[0034] One end of the first movable plate 7 away from the first limiting module 2 is provided with a first supporting unit 71, and one end of the second movable plate 8 away from the second limiting module 3 is provided with a second supporting unit 81. When the insertion end extends into the adhesive application groove 4, the first supporting unit 71 fits with the bonding groove surface 41, and the second movable plate 8 fits with the opposite groove surface of the bonding groove surface 41. When the first limiting module 2 presses the adhesive tape to fit with the groove surface, the first supporting unit fits with the same-side groove surface. When the second limiting module 3 presses the adhesive tape to fit with the opposite-side groove surface, the second supporting unit also fits with the opposite-side groove surface. The four together form a stable four-point support with the inner groove surface of the adhesive application groove, making the adhesive application operation easier to complete. Especially during the initial positioning, the second supporting unit 81 can be set at a position corresponding to the first limiting module. During positioning, first, contact the groove surface through the second supporting unit 81 to find the pasting position, and then make the second limiting module press the adhesive tape to fit with the groove surface. At this time, the second movable plate 8 is supported by two support points, namely the second supporting unit and the second limiting module, making the subsequent process of the first limiting module driving the adhesive surface of the adhesive tape to approach and paste on the adhesive application groove surface more stable.

[0035] Preferably, both the first supporting unit 71 and the second supporting unit 81 are roller structures, making the sliding operation smoother during the process of pasting the adhesive tape.

[0036] The guiding mechanism 6 is arranged on the outer side surface of the first movable plate 7 or the outer side surface of the second movable plate 8. The guiding mechanism 6 includes a plurality of guiding rollers 61, and the plurality of guiding rollers 61 are arranged along the length direction of the rubber strip 4 that is clamped and limited. By the contact between the rollers and the notch, the smoothness of the rubber strip pasting operation is further improved.

[0037] The guiding mechanism 6 is connected to the sliding seat 60. The sliding seat 60 is slidably arranged on the first movable plate 7 or the second movable plate 8 and is used for sliding and adjusting the guiding mechanism 6 to be close to or far away from the inserting end. By adjusting the position of the sliding seat 60, the distance between the rubber strip pasting position and the edge of the notch is adjusted, and the adaptability is further improved.

[0038] The bottom surface of the annular groove 31 includes a plurality of blade-shaped supporting edges. The contact area between the second limiting module 3 and the adhesive surface of the rubber strip 5 can be further reduced. Preferably, the tips of the supporting edges are rounded to ensure that only a pressing force is applied to the rubber strip during rolling without generating cutting marks.

[0039] Based on the structure of the above rubber strip pasting device, the specific rubber strip pasting method includes the following steps:

[0040] Step Ⅰ, cut a rubber strip 5 with a preset length, insert one end of the rubber strip 5 into the card slot 21, insert the middle part of the rubber strip 5 into the annular groove 31, and keep the rubber strip 5 between the two clamping points straight;

[0041] Step Ⅱ, adjust the distance between the first movable plate 7 and the second movable plate 8 through the adjusting mechanism 9 until the width of the inserting end is narrower than the width of the rubber strip pasting groove 4;

[0042] Step Ⅲ, insert the inserting end into the rubber strip pasting groove 4. First, make the guiding mechanism 6 fit with the end face of the notch of the rubber strip pasting groove 4, and determine the starting position of rubber strip pasting by sliding and fine-tuning along the notch direction, so that the end of the rubber strip inserted into the card slot 21 corresponds to the starting position of rubber strip pasting;

[0043] Step Ⅳ, after determining the position, first press the rubber strip 5 through the second limiting module 3 to make it fit with the opposite groove surface of the bonding groove surface 41, and then press the end of the rubber strip 5 through the first limiting module 2 to paste it with the bonding groove surface 41;

[0044] Step Ⅴ, slide along the notch direction of the rubber strip pasting groove 4 in the direction away from the first limiting module 2 until the whole rubber strip 5 is bonded and fitted with the bonding groove surface 41.

[0045] Based on the above steps, it is realized to press and paste from one end of the rubber strip to the other end on the side groove surface of the groove on the back panel of the TV. The accuracy of the pasting position is ensured, the deviation of the pasting track is avoided, and the flatness and pasting quality of the pasted rubber strip are guaranteed.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the above principles of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
