Description

Technical Field

[0001] This utility model relates to the field of automatic glue application technology, and in particular to an automatic feeding and glue application device. Background Technology

[0002] During the assembly of the TV back panel and screen, precise adhesive needs to be applied to the edges of the back panel to achieve sealing, dust prevention, and structural reinforcement. Currently, automated production lines generally use conveyor belts to directly transport the back panel to the adhesive application station for positioning and adhesive application.

[0003] In continuous automated production processes, the constant operation of the conveyor belt can easily cause deviations in the position of the back plate. Furthermore, the flexible nature of the belt surface makes the back plate prone to swaying, slippage, and deviation, making it difficult to meet the accuracy requirements of the adhesive application trajectory. Secondly, traditional positioning structures directly and rigidly position the back plate on the conveyor belt, which can easily scratch the back plate surface or cause damage by pressing on brittle edges.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0023] This application discloses an automatic feeding and gluing device, such as... Figure 1 and Figure 2As shown, it includes a conveyor belt 11 and a corresponding lifting mechanism 2, a straightening mechanism 3 and a gluing mechanism 4. The lifting mechanism 2 and the straightening mechanism 3 are located on the upper and lower sides of the conveyor belt 11, respectively, and the gluing mechanism 4 is located above the straightening mechanism 3.

[0024] In the specific implementation process, the TV back panel is transported to the top of the lifting mechanism 2 via the conveyor belt 11. The lifting mechanism 2 then lifts the TV back panel off the conveyor belt 11, positioning it in the inner circle of the alignment mechanism 3. This facilitates the positioning and fixing of the TV back panel on the lifting mechanism 2 by the alignment mechanism 3. Finally, the gluing mechanism 4 applies glue to the TV back panel. After the glue is applied, the lifting mechanism 2 places the TV back panel back onto the conveyor belt 11, which carries away the glued back panel. At the same time, the back panel to be glued is moved to the lifting mechanism 2, thus realizing automated glue application.

[0025] The lifting mechanism 2 includes a first power component 21, a lifting frame 22, and support rods 23. Multiple support rods 23 are vertically arranged on the lifting frame 22 corresponding to the conveyor belt 11. The lifting frame 22 is driven to move in the vertical direction by the first power component 21. The multiple support rods 23 on the lifting frame 22 are driven by the first power component 21 to lift or lower the back plate on the conveyor belt 11.

[0026] The correction mechanism 3 includes a first correction component 31 and a second correction component 32 disposed on the outer ring of the conveyor belt 11. The first correction component 31 and the second correction component 32 are each arranged in two sets opposite to each other and are driven to move in mutually perpendicular directions by the third power component 33 and the fourth power component 34, respectively. The two sets of first correction components 31 and the two sets of second correction components 32 are respectively disposed around the back plate and complete the positioning and fixing of the back plate under the drive of the third power component 33 and the fourth power component 34.

[0027] The adhesive application mechanism 4 includes a first linear module 41, a second linear module 42, and a third linear module 43 respectively arranged along the x, y, and z axes. The second linear module 42 is disposed on the first linear module 41, and the third linear module 43 is disposed on the second linear module 42. An adhesive application device 44 is disposed on the third linear module 43. The first linear module 41 and the second linear module 42 drive the adhesive application device 44 to move in the horizontal direction, and the third linear module 43 drives the adhesive application device 44 to move in the vertical direction.

[0028] In this embodiment, as Figure 6The schematic diagram of the lifting mechanism 2 shown is shown. The lifting mechanism 2 is mounted on the first support 24. A first guide rail 25 is provided on the first support 24 in a vertical direction. The lifting frame 22 is slidably connected to the first support 24 through the first guide rail 25. The first power assembly 21 includes a worm gear assembly 211 and a first motor 212 and a lead screw 213 respectively connected to its input shaft and output shaft. The lead screw 213 is vertically mounted and a drive seat 214 is screwed onto it. The drive seat 214 is fixedly connected to the lifting frame 22.

[0029] The first motor 212 provides kinetic energy to the worm gear assembly 211, causing its output shaft to drive the lead screw 213 to rotate, which in turn drives the drive seat 214 on the lead screw 213 to move along the length of the lead screw 213. The drive seat 214 is fixedly connected to the lifting seat, realizing the vertical reciprocating motion of the lifting seat.

[0030] In the specific implementation process, two worm gear assemblies 211 are symmetrically arranged on both sides of the lifting frame 22. The input shafts of the two worm gear assemblies 211 are synchronously driven through the connecting shaft. The two worm gear assemblies 211 drive the drive seats 214 on the two lead screws 213 respectively, thereby driving the lifting frame 22 to move synchronously up and down on both sides, so as to achieve the smooth movement of the lifting frame 22.

[0031] In this embodiment, as Figure 1 and Figure 5 As shown, the conveyor belt 11 is mounted on the second support 12, and multiple support rods 23 are spaced apart along its width direction. Multiple support rods 23 are arranged between adjacent conveyor belts 11 along the length direction of the conveyor belt 11. The support rods 23 are staggered with the conveyor belts 11 so that their driving processes do not interfere with each other.

[0032] Furthermore, the conveyor belt 11 is driven to transport by the second power assembly 13, and a baffle 14 is provided on the second support 12 at the front end of the conveyor belt 11 in the conveying direction. The baffle 14 is located between two adjacent conveyor belts 11 and is driven to move in the vertical direction by the lifting cylinder 15.

[0033] The baffle 14 installed on the second support 12 blocks and limits the forward movement of the back plate. The baffle 14 is driven by the lifting cylinder 15 to protrude or retract into the plane of the conveyor belt 11.

[0035] The first positioning roller 312 and the second positioning roller 322, which are set on the crossbeam 311 and the longitudinal beam 321, abut against the edge of the back plate and adjust the horizontal position of the back plate; the first positioning roller 312 and the second positioning roller 322 are set vertically in the axial direction to avoid the edge of the back plate being damaged by friction with the positioning rollers during the adjustment process.

[0036] Furthermore, multiple first positioning rollers 312 are arranged along the length of the crossbeam 311. A first cylinder 313 is provided on the crossbeam 311 corresponding to the first positioning roller 312. The first positioning roller 312 is driven by the first cylinder 313 to move along the length of the crossbeam 311. Multiple second positioning rollers 322 are arranged along the length of the longitudinal beam 321. A second cylinder 323 is provided on the longitudinal beam 321 corresponding to the second positioning roller 322. The second positioning roller 322 is driven by the second cylinder 323 to move along the length of the longitudinal beam 321. A platform 37 is provided at the bottom of both the crossbeam 311 and the longitudinal beam 321 along their length. A positioning groove 371 is provided at the edge of each platform 37. A sliding groove 372 is provided on the platform 37 corresponding to the moving path of the first positioning roller 312 or the second positioning roller 322, and one end of the sliding groove 372 extends to the positioning groove 371.

[0037] In the specific implementation process, the back panel is first supported by the lifting mechanism 2. The third and fourth drive components drive the crossbeam 311 and the longitudinal beam 321 to move toward the back panel, and the position of the back panel on the lifting mechanism 2 is initially adjusted. At this time, the platform 37 on the crossbeam 311 and the longitudinal beam 321 is located below the back panel. The lifting mechanism 2 is retracted so that the back panel falls onto the platform 37. Then, the first cylinder 313 and the second cylinder 323 drive the first positioning roller 312 or the second positioning roller 322 to make a second precise adjustment of the horizontal position of the back panel. Finally, the edge of the back panel is driven into the positioning groove 371 of the platform 37, and the positioning and fixing of the back panel around the perimeter is completed, ensuring the stability of the back panel position during the glue application process.

[0038] Furthermore, the third power assembly 33 includes a third cylinder 331 and a first slide rail 332. The crossbeam 311 is slidably connected to the third support 36 via the first slide rail 332 and is driven to move along the length of the longitudinal beam 321 by the third cylinder 331.

[0039] The third cylinder 331 is connected to the middle of the crossbeam 311.
