Description

Technical Field

[0001] The utility model relates to the technical field of PCB solder paste wiping, in particular to a light bar PCB solder paste wiping device. Background Art

[0002] On display devices such as televisions, light strips are usually required as the light source of the backlight module of the display device to ensure the normal use of the backlight module. During the production process of the light strip, a printer will be used to print solder paste on the pad of the light strip PCB to facilitate the soldering of the light strip later. During the tin printing process of the printer, the printing of solder paste sometimes produces undesirable conditions such as offset, too much tin, or too little tin, which affects the subsequent soldering process. Therefore, before soldering the light strip PCB, the poorly printed solder paste on the light strip PCB needs to be wiped off.

[0003] However, in the current production process of light strips, bad solder paste on the light strip PCB is wiped manually. Manual wiping easily causes solder paste residue, affecting the subsequent processes of the light strip PCB. At the same time, manual wiping of the light strip PCB pad will also increase the workload of operators and affect the overall production efficiency. Utility Model Content

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] At present, in the production process of light strips, manual wiping is used to wipe the bad solder paste on the light strip PCB. However, manual wiping is likely to cause solder paste residue, affecting the subsequent process of the light strip PCB. At the same time, manual wiping of the light strip PCB pad will also increase the workload of the operator and affect the overall production efficiency. Therefore, a light strip PCB solder paste wiping device is proposed to solve the above problems.

[0034] The scheme is further illustrated by the following examples:

[0035] See also Figure 1 In this embodiment, for the convenience of explanation, Figure 1 The CC direction is the longitudinal direction of the wiping device, the DD direction is the transverse direction of the wiping device, and the EE direction is the vertical direction of the wiping device.

[0036] The light bar PCB solder paste wiping device of this embodiment is used to wipe the bad solder paste on the light bar PCB1 to ensure the normal use of the light bar.

[0037] See also Figure 1 and Figure 2 In this embodiment, the wiping device includes a frame, a wiping mechanism 20, a light bar plate 30 and a clamping mechanism 40. Among them, a workbench 10 is provided on the frame, and the wiping mechanism 20 is used to wipe the light bar PCB1, and the wiping mechanism 20 is located above the workbench 10. At the same time, the light bar plate 30 is used to place and fix the light bar PCB1, and the clamping mechanism 40 is used to place the light bar plate 30, and the clamping mechanism 40 is provided on the workbench 10 and is located directly below the wiping mechanism 20, so that the wiping mechanism 20 can wipe the light bar PCB1 on the light bar plate 30 placed on the clamping mechanism 40 after moving in the vertical direction.

[0038] Specifically, the wiping mechanism 20 can extend in the transverse direction, that is, extend in the transverse direction to the top of the clamping mechanism 40. At the same time, a plurality of light bar PCB1 can be fixed on the light bar disc 30, and the length direction of the light bar PCB1 is the same as the length direction of the light bar disc 30, that is, the length directions of the light bar disc 30 and the light bar PCB1 both extend in the longitudinal direction. In addition, the clamping mechanism 40 includes a clamping table 41 and a sliding member 42. Among them, the clamping table 41 is used to place and clamp the light bar disc 30, the sliding member 42 is arranged on the workbench 10, and can move in the transverse direction relative to the workbench 10, the clamping table 41 is fixedly connected to the sliding member 42, and the clamping table 41 and the light bar disc 30 can slide with the sliding member 42 and move in the transverse direction.

[0039] It should be noted that when the clamping platform 41 and the light bar plate 30 slide with the sliding member 42, the projections of the clamping platform 41 and the wiping mechanism 20 in the vertical direction can be misaligned, so that the wiping mechanism 20 can avoid the light bar plate 30 in the vertical direction, which is convenient for installing or unloading the light bar plate 30 on the clamping platform 41. That is, in this embodiment, the clamping platform 41 and the light bar plate 30 can move between the loading station and the wiping station with the sliding member 42. When the clamping platform 41 and the light bar plate 30 are in the wiping station, they are just below the wiping mechanism 20. At this time, the wiping mechanism 20 can wipe the light bar PCB1 on the light bar plate 30. When the clamping platform 41 and the light bar plate 30 are in the loading station, they are misaligned with the wiping mechanism 20 in the vertical direction. At this time, the installation or unloading of the light bar plate 30 can be completed conveniently and quickly.

[0040] In addition, in this embodiment, the installation and unloading of the light bar tray 30, and the movement of the clamping platform 41 and the light bar tray 30 are all completed manually. That is, the light bar tray 30 is installed on the clamping platform 41 manually, and the clamping platform 41 and the light bar tray 30 are manually pushed from the loading station to the wiping station along the sliding member 42, and the wiping mechanism 20 wipes the light bar PCB1 on the light bar tray 30. After the wiping mechanism 20 completes wiping, the clamping platform 41 and the light bar tray 30 are manually moved from the wiping station to the loading station, and the light bar tray 30 is removed from the clamping platform 41, thereby completing a wiping process.

[0041] See also Figure 3-5The wiping mechanism 20 includes a wiping rail 21, a moving unit 22, a wiping unit 23 and a spraying unit 24. The wiping rail 21 is fixed on the workbench 10, and the length direction of the wiping rail 21 itself extends in the longitudinal direction. The moving unit 22 is installed on the wiping rail 21 and can slide in the longitudinal direction along the wiping rail 21. The wiping unit 23 is used to wipe the light bar PCB1, and the spraying unit 24 is used to spray the wiping unit 23 with a wiping agent. In this embodiment, the wiping unit 23 and the spraying unit 24 are both installed on the moving unit 22 and extend in the lateral direction, so that the wiping unit 23 and the spraying unit 24 can be located directly above the wiping station, that is, they can be located directly above the clamping table 41 and the light bar plate 30, so as to be able to face the light bar plate 30 in the vertical direction, so that the wiping unit 23 can abut against the light bar PCB1 on the light bar plate 30 and complete the wiping.

[0042] In this embodiment, the wiping unit 23 is driven by the moving unit 22 to move longitudinally on the wiping rail 21 and along the length direction of the light bar plate 30 and the light bar PCB1, thereby completing the wiping of the light bar PCB1.

[0043] Specifically, the moving unit 22 includes a moving slider and a driving assembly. The moving slider is slidably connected to the wiping rail 21. The wiping unit 23 and the spraying unit 24 are both mounted on the moving slider and follow the moving slider to move along the wiping rail 21. The driving assembly is mounted on the side of the wiping rail 21 and is used to drive the moving slider to move along the wiping rail 21. In this embodiment, the driving assembly includes a servo motor and a driving chain to drive the moving slider to move along the wiping rail 21. Of course, the driving assembly can also be set as a servo motor and a screw to drive the moving slider to move along the wiping rail 21.

[0044] See also Figure 4 The wiping unit 23 includes a wiping frame 231, a wiping head 232, a dust-free cloth 233, a wiping motor 237 and two rollers 234. Among them, the wiping frame 231 is fixed on the moving unit 22, that is, installed on the moving slider. The roller 234 is rotatably installed on the wiping frame 231 and extends to the top of the clamping mechanism 40, that is, extends in the horizontal direction. The two rollers 234 are arranged in parallel in the horizontal direction, and the axial direction of the roller 234 itself extends in the horizontal direction, that is, the two rollers 234 are parallel to the clamping table 41 and the light bar disk 30 located on the wiping station. In this embodiment, the roller 234 is installed on the wiping frame 231 through the wiping motor 237, so that the wiping motor 237 can drive the roller 234 to rotate.

[0045] At the same time, the dust-free cloth 233 is connected between the two rollers 234 and can be released and reeled in with the rotation of the rollers 234, so that the dust-free cloth 233 remains clean during the wiping process. The wiping head 232 is movably mounted on the wiping frame 231 in the vertical direction and is located between the two rollers 234, so that the wiping head 232 can drive the dust-free cloth 233 to fit on the light bar of the light bar plate 30, so that the dust-free cloth 233 can wipe the light bar PCB1 on the light bar plate 30.

[0046] See also Figure 5 The wiping unit 23 further includes a wiping cylinder 235 and a guide rod 236. The guide rod 236 is connected between the wiping head 232 and the wiping frame 231 to enable the wiping head 232 to move in the vertical direction and to limit the moving track of the wiping head 232 to prevent the wiping head 232 from shaking during the movement. The wiping cylinder 235 is connected between the wiping head 232 and the wiping frame 231 to drive the wiping head 232 to move, so that the dust-free cloth 233 is attached to or away from the light bar PCB1 on the light bar plate 30.

[0047] See also Figure 4 , the spraying unit 24 includes a spraying bracket 241 and two nozzles 242. The spraying bracket 241 is mounted on the mobile unit 22 and is located on the side of the wiping bracket 231. The two nozzles 242 are slidably connected to the spraying bracket 241 and can be aligned with the dust-free cloth 233 so that the nozzles 242 can spray the wiping agent on the dust-free cloth 233. It should be noted that, in the present embodiment, the nozzles 242 can spray the alcohol wiping agent, thereby improving the wiping efficiency of the wiping unit 23. It should be noted that the spraying bracket 241 is provided with a slide rail, and the two nozzles 242 are slidably connected to the spraying bracket 241, and the spraying position of the nozzle 242 on the dust-free cloth 233 can be adjusted, thereby adjusting the spraying effect of the nozzle 242 on the dust-free cloth 233, and ensuring that the dust-free cloth 233 remains moist during the wiping process.

[0048] See also Figure 6-8 A plurality of lamp slots 31 for fixing the light bar PCB1 are provided on the light bar plate 30, so that the light bar plate 30 can load a plurality of light bar PCB1 at a time, thereby improving the wiping efficiency of the wiping device.

[0049] Specifically, the lamp slot 31 extends along the length direction of the light bar. It should be noted that when the light bar PCB1 is placed in the lamp slot 31, the upper surface of the light bar PCB1 is at least flush with or higher than the upper surface of the light bar plate 30, so as to ensure that when the wiping unit 23 moves in the longitudinal direction, the wiping head 232 and the dust-free cloth 233 can wipe the light bar PCB1 and ensure the wiping effect.

[0050] See also Fig. 9 and Fig.10The clamping platform 41 includes a bottom plate 43, a clamping group 44, and two support components 45. The bottom plate 43 is fixedly connected to the sliding member 42 so that the clamping platform 41 can move along the sliding member 42. The two support components 45 are arranged on the bottom plate 43 at intervals, and the two support components 45 are respectively pressed against the two sides of the light bar plate 30 in the transverse direction to support the light bar plate 30. At the same time, the clamping group 44 is installed on the bottom plate 43 and is located between the two support components 45. In this embodiment, the clamping group 44 is clamped at both ends of the light bar plate 30 in the longitudinal direction.

[0051] Specifically, the clamping assembly 44 includes a clamping rail 441 and a clamping slider 442. The clamping rail 441 is fixed on the bottom plate 43, and the length direction of the clamping rail 441 itself extends in the longitudinal direction. The clamping slider 442 is installed on the clamping rail 441 and can slide relative to the clamping rail 441 to clamp and limit the two sides of the light bar plate 30 in the longitudinal direction.

[0052] It should be noted that a protrusion 443 is provided on the clamping slider 442. The protrusion 443 is provided on the top of the clamping slider 442 and is located on the side of the clamping slider 442 facing the light bar plate 30 so that the protrusion 443 can abut against the side of the light bar plate 30.

[0053] In this embodiment, the support assembly 45 includes a plurality of support plates 451 , and the plurality of support plates 451 are arranged in parallel along the length direction of the light bar plate 30 , that is, arranged in parallel along the longitudinal direction.

[0054] It should be noted that the clamping platform 41 is also provided with a panel 46. The panel 46 is provided on the side of the support assembly 45, and the top of the panel 46 is higher than the top of the support assembly 45, so that when the light bar plate 30 is placed on the clamping platform 41, the panel 46 can limit the side of the light bar plate 30. In this embodiment, at least three panels 46 are provided, and the three panels 46 are all against the side of the light bar plate 30 and cooperate with the clamping slider 442 to fasten the light bar plate 30.

[0055] In addition, in this embodiment, the sliding member 42 is provided with a slider and a slide rail, wherein the slide rail is fixedly connected to the base plate 43 , the slider is fixed to the workbench 10 , and the slider and the slide rail are slidably connected so that the clamping table 41 can slide relative to the workbench 10 .

[0056] In summary, multiple light bar PCB1 are placed in the light groove 31 of the light bar disk 30, and the light bar disk 30 is fixed on the clamping table 41, and the clamping table 41 and the light bar disk 30 are manually pushed from the loading station to the wiping station. Then the wiping mechanism 20 is started to wipe the light bar PCB1 on the light bar disk 30 to remove the defective tin printing on the light bar PCB1. When the wiping work is completed, the clamping table 41 and the light bar disk 30 are manually moved from the wiping station to the loading station, and the light bar disk 30 is unloaded from the clamping table 41, thereby completing the entire wiping process. Since the wiping mechanism 20 wipes multiple light bar PCB1 at the same time, and the wiping unit 23 and the spraying unit 24 can ensure the wiping efficiency of the wiping mechanism 20 on the light bar PCB1, the wiping equipment can improve the wiping efficiency of defective tin printing.

[0057] It should be noted that, in the present embodiment, a label for identification, such as a QR code or a bar code, is provided on the light bar PCB1. After the light bar PCB1 is placed on the light bar plate 30, the model and length of the light bar PCB1 are confirmed by scanning the identification label, thereby transmitting the data to the wiping mechanism 20, so that the wiping mechanism 20 can wipe according to the model and length of the light bar PCB1, thereby saving the wiping time of the wiping mechanism 20 and improving the wiping efficiency.
