Description

Technical Field

[0001] This utility model relates to the field of adhesive dispensing technology for television back panels, specifically a hot-press positioning device for adhesive dispensing on television back panels. Background Technology

[0002] Applying adhesive to the back panel of a TV can enhance the adhesion between the screen and the back panel, effectively preventing problems such as loosening, separation, or deformation between the screen and the back panel. However, in the positioning of the back panel to be adhesiveped, a positioning device is often required to perform the positioning operation.

[0003] For example, application number 201822230617.9 discloses a TV back panel dispensing hot press machine, including a back panel dispensing cabinet, a back panel hot press cabinet on the side of the back panel dispensing cabinet, a dispensing control cabinet on the front of the back panel dispensing cabinet, a hot press cabinet door at the bottom of the front of the back panel hot press cabinet, a back panel removal cabinet door at the top of the hot press cabinet door, a hot press plate on the top surface of the back panel hot press cabinet, a hot press control cabinet on one side of the back panel hot press cabinet, a dispensing base plate on the top surface of the back panel dispensing cabinet, a back panel fixing clip on the top of the dispensing base plate, and a TV dispensing back panel on the inner side of the back panel fixing clip. In this utility model, the dispensing machine can move laterally and longitudinally along the first and second slide rails via the dispensing control cabinet, ensuring that the dispensing machine can automatically and accurately apply the glue to the frame position. The glue amount, thickness, application speed, dispensing time, and stop time can be controlled by the dispensing tube and the pressure gun, ensuring stable glue output and no glue leakage.

[0004] However, although this hot press dispensing machine can dispense glue to the back panel of a TV, its positioning and correction effect on the back panel is not high. This results in the back panel being misaligned during dispensing, causing the glue dispensing position to shift and reducing the effectiveness of the glue dispensing.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a hot-pressing positioning device for dispensing adhesive on the back panel of a television. Utility Model Content

[0006] The purpose of this utility model is to provide a hot-press positioning device for dispensing adhesive on a TV back panel, so as to solve the problem mentioned in the background art that the positioning effect of the TV back panel to be dispensed is not high, thus reducing the dispensing effect on the TV back panel.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot-pressing positioning device for dispensing adhesive on a television back panel, comprising a device body and a positioning mechanism disposed on the outer wall of the device body, wherein the positioning mechanism includes a sliding component;

[0008] The sliding assembly includes a push block and a slider. An adjusting rod is slidably connected to the outer wall of the main body of the device. A lifting rod is slidably connected to the outer wall of the adjusting rod. A dispensing machine is slidably connected to the outer wall of the lifting rod. A TV back panel is placed on the outer wall of the main body of the device. A fixing block is fixedly connected to the outer wall of the main body of the device. A limit roller is provided on the outer wall of the fixing block. An electric push rod is fixedly connected to the outer wall of the main body of the device. A push block is slidably connected to the output end of the electric push rod. A slide rail is fixedly connected to the outer wall of the push block. A slider is slidably connected to the outer wall of the slide rail. A spring is sleeved on the outer wall of the slide rail and fixedly connected to the outer wall of the slider. A rotating plate is rotatably connected to the outer wall of the slider. A correction roller is provided on the outer wall of the rotating plate.

[0009] Furthermore, a fixed box is fixedly connected to the outer wall of the slider, a micro drive motor is fixedly connected to the outer wall of the fixed box, and a worm gear that is rotatably connected to the inner wall of the fixed box is fixedly connected to the output end of the micro drive motor. A worm wheel that is rotatably connected to the inner wall of the fixed box is engaged with the outer wall of the worm gear.

[0010] Furthermore, there are two sets of fixed blocks, which are positioned at right angles to each other, and two sets of limiting rollers, which are positioned symmetrically about the central axis of the fixed blocks.

[0011] Furthermore, a pushing groove is provided at the connection between the outer wall of the main body of the device and the pushing block.

[0012] Furthermore, the other end of the spring is fixedly connected to the outer wall of the push block, and two sets of springs are provided, with the positions of the two sets of springs being symmetrical about the central axis of the push block.

[0013] Furthermore, the rotating plate is provided in two sets, and the positions of the two sets of rotating plates are symmetrical about the central axis of the slider.

[0015] Furthermore, the worm gear has two sets of helices, which rotate in opposite directions, and the worm wheels have two sets, which are symmetrical about the central axis of the slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of the correction roller, improves the positioning effect of the TV back panel when applying glue to it using a hot press. An electric push rod can be activated to drive the push block to slide along the outer wall of the push groove, thus bringing the correction roller into contact with the TV back panel. The limiting action of the fixing block and the limiting roller causes the slider to slide along the outer wall of the slide rail. The compression of the correction roller causes the TV back panel to adhere to the limiting roller, thus correcting the diagonal position of the TV back panel. This achieves improved control of the glue application effect when applying glue to the TV back panel using a hot press.

[0018] 2. This utility model, through the setting of the worm gear, improves the convenience of adjusting the opening amplitude of the correction roller when positioning the TV back panel to be glued using the positioning device, and meets the needs of TV back panels of different sizes. The micro drive motor can be turned on to drive the worm gear to rotate through the rotation of the worm. The rotation of the worm gear drives the rotating plate to rotate, which plays the role of adjusting the opening amplitude of the correction roller. This realizes improved control of the positioning effect of TV back panels of different sizes when positioning the TV back panel to be glued using the positioning device. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-3 As shown, a hot-pressing positioning device for dispensing adhesive on the back panel of a television includes a device body 1 and a positioning mechanism disposed on the outer wall of the device body 1. The positioning mechanism includes a sliding component.

[0027] The sliding assembly includes a push block 9 and a slider 12. An adjusting rod 2 is slidably connected to the outer wall of the main body 1. A lifting rod 3 is slidably connected to the outer wall of the adjusting rod 2. A dispensing machine 4 is slidably connected to the outer wall of the lifting rod 3. A TV back panel 5 is placed on the outer wall of the main body 1. A fixing block 6 is fixedly connected to the outer wall of the main body 1. A limit roller 7 is provided on the outer wall of the fixing block 6. An electric push rod 8 is fixedly connected to the outer wall of the main body 1. A push block 9 is slidably connected to the outer wall of the main body 1 at the output end of the electric push rod 8. A slide rail rod 11 is fixedly connected to the outer wall of the push block 9. A slider 12 is slidably connected to the outer wall of the slide rail rod 11. A spring 13 is sleeved on the outer wall of the slide rail rod 11 and fixedly connected to the outer wall of the slider 12. A rotating plate 14 is rotatably connected to the outer wall of the slider 12. A correction roller 15 is provided on the outer wall of the rotating plate 14.

[0028] Furthermore, there are two sets of fixing blocks 6, which are positioned at right angles. There are also two sets of limiting rollers 7, which are symmetrical about the central axis of the fixing blocks 6. This arrangement of the two sets of fixing blocks 6 at right angles facilitates the positioning control of the main body 5 of the TV back panel.

[0029] Furthermore, a push groove 10 is provided at the connection between the outer wall of the main body 1 and the push block 9. The push block 9 forms a sliding structure with the push groove 10 through the electric push rod 8, which is conducive to the electric push rod 8 driving the push block 9 to slide along the outer wall of the push groove 10, thereby realizing the control operation of the sliding of the correction roller 15.

[0030] Furthermore, the other end of the spring 13 is fixedly connected to the outer wall of the push block 9. There are two sets of springs 13, and the positions of the two sets of springs 13 are symmetrical about the central axis of the push block 9. The slider 12 forms a sliding structure with the slide rail rod 11 through the springs 13. This facilitates the control operation of limiting the slider 12 by setting the positions of the two sets of springs 13 symmetrical about the central axis of the push block 9.

[0031] Furthermore, two sets of rotating plates 14 are provided, and the positions of the two sets of rotating plates 14 are symmetrical about the central axis of the slider 12. This symmetrical arrangement of the two sets of rotating plates 14 about the central axis of the slider 12 helps to improve the positioning effect of the TV back panel to be glued.

[0032] Example 2

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes a hot-press positioning device for dispensing adhesive on a TV back panel. Compared to Embodiment 1, as another implementation of this utility model, a fixing box 16 is fixedly connected to the outer wall of the slider 12, and a micro drive motor 17 is fixedly connected to the outer wall of the fixing box 16. A worm gear 18, which is rotatably connected to the inner wall of the fixing box 16, is fixedly connected to the output end of the micro drive motor 17. A worm wheel 19, which is rotatably connected to the inner wall of the fixing box 16, meshes with the outer wall of the worm gear 18. By setting the worm wheel 19, it is beneficial to improve the convenience of adjusting the opening amplitude of the correction roller 15 when positioning the TV back panel to be dispensed using the positioning device, and to meet the needs of TV back panels of different sizes. The micro drive motor 17 can be turned on to drive the worm wheel 19 to rotate through the rotation of the worm gear 18. The rotation of the worm wheel 19 drives the rotating plate 14 to rotate, which plays the role of adjusting the opening amplitude of the correction roller 15. This realizes improved control of the positioning effect of TV back panels of different sizes when positioning the TV back panel to be dispensed using the positioning device.

[0034] Furthermore, the rotation center of the worm gear 19 is fixedly connected to the rotating plate 14 via a connecting shaft. The rotation center of the rotating plate 14 coincides with the rotation center of the worm gear 19. The rotating plate 14 forms a rotating structure with the slider 12 via the worm gear 19, which facilitates the rotation of the worm 18. The rotation of the worm gear 19 drives the rotating plate 14 to rotate, thereby realizing the control operation of adjusting the opening amplitude of the straightening roller 15.

[0035] Furthermore, the worm gear 18 has two sets of spirals, and the two sets of spirals rotate in opposite directions. The worm wheel 19 has two sets, and the position distribution of the two sets of worm wheels 19 is symmetrical about the central axis of the slider 12. This arrangement of the two sets of worm wheels 19 with their position distribution symmetrical about the central axis of the slider 12 facilitates the control operation of the two sets of rotating plates 14 rotating in opposite directions.

[0036] Working principle: When using this TV back panel dispensing hot press positioning device, firstly, when dispensing glue to the TV back panel through the dispensing hot press, in order to improve the positioning effect of the TV back panel to be dispensed, the electric push rod 8 can be opened to drive the push block 9 to slide along the outer wall of the push groove 10, so that the correction roller 15 contacts the TV back panel. Through the limiting effect of the fixed block 6 and the limiting roller 7, the slider 12 slides along the outer wall of the slide rail rod 11. Through the squeezing of the correction roller 15, the TV back panel is made to fit with the limiting roller 7, which plays a role in correcting the position of the TV back panel. This achieves the control operation of improving the glue dispensing effect of the TV back panel when dispensing glue to the TV back panel through the dispensing hot press.

[0037] Finally, when positioning the TV back panel to be glued using the positioning device, in order to improve the convenience of adjusting the opening amplitude of the straightening roller 15 and meet the needs of TV back panels of different sizes, the micro drive motor 17 can be turned on to drive the worm wheel 19 to rotate through the rotation of the worm gear 18. The rotation of the worm wheel 19 drives the rotating plate 14 to rotate, which plays the role of adjusting the opening amplitude of the straightening roller 15. This improves the control of the positioning effect of TV back panels of different sizes when positioning the TV back panel to be glued using the positioning device.

[0038] This is the working principle of the adhesive hot-press positioning device for the back panel of a television.
