Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0026] Please refer to Figure 1-8 , the present utility model provides a technical solution: an automatic glue brushing device for patch diodes, including a bracket 1, a moving seat 2, a glue delivery tube 3, a glue brushing head 4 and a base 6. A supporting plate 5 is arranged on the top of the base 6, a clamping mechanism 9 is arranged on the top of the supporting plate 5, and a sliding plate 7 is arranged on the top of the base 6;

[0027] The clamping mechanism 9 includes two sliding bars 901, a plurality of first clamping plates 902, two first connecting rods 903 and a second connecting rod 904. The sliding bars 901 are arranged on both sides of the supporting plate 5. The first clamping plates 902 are fixedly connected between the tops of the two sliding bars 901. The surface of the first clamping plate 902 is in contact with the top of the supporting plate 5. The rear side of the first connecting rod 903 is fixedly connected to the front side of the sliding bar 901. The second connecting rod 904 is fixedly connected between the opposite sides of the two first connecting rods 903.

[0028] In this embodiment: First, place the surface mount diode that needs to be glued on the top of the pallet 5, and then rotate the rotating column 19. When the rotating column 19 rotates, it can drive the slide bar 901 and the first clamping plate 902 to move, so that the first clamping plate 902 and the second clamping plate 15 clamp the surface mount diode that needs to be glued on the top of the pallet 5. Then, place the pallet 5 on the top of the slide plate 7, so that the limiting block 11 contacts the inside of the limiting groove 14, and the pallet 5 can be limited on the top of the slide plate 7. Then, set the corresponding program for the automatic surface mount diode gluing machine, and then control the automatic surface mount diode gluing machine to work. At this time, the surface mount diode that needs to be glued on the top of the pallet 5 can be glued. By using the relatively large-volume pallet 5 to clamp and glue a relatively large number of surface mount diodes that need to be glued, it can be avoided that when the automatic surface mount diode gluing machine glues the surface mount diode that needs to be glued, only a small number or a single surface mount diode that needs to be glued can be placed on the top of the slide plate 7, and the bristles at the bottom of the gluing head 4 are used to glue the surface mount diode that needs to be glued. When gluing a large number of surface mount diodes that need to be glued, the efficiency is low, and there is no structure for limiting the surface mount diode that needs to be glued, so that when the gluing head 4 glues the surface mount diode that needs to be glued, the surface mount diode that needs to be glued is likely to be displaced, affecting the gluing effect of the surface mount diode that needs to be glued, and thus affecting the use effect.

[0029] As a technical optimization scheme of the present utility model, sliding grooves 17 are opened on both sides of the pallet 5, and one side of the slide bar 901 close to the sliding groove 17 extends into the inside of the sliding groove 17 and is movably connected with the inside of the sliding groove 17.

[0030] In this embodiment: By sliding the slide bar 901 inside the sliding groove 17, the slide bar 901 can move, achieving the effect of facilitating the sliding of the slide bar 901.

[0031] As a technical optimization scheme of the present utility model, a second clamping plate 15 is fixedly connected to the top of the pallet 5. The number of the second clamping plates 15 is several. Protective pads 10 are fixedly connected to the opposite sides of the first clamping plate 902 and the second clamping plate 15, and the number of the protective pads 10 is several.

[0032] In this embodiment: After the first clamping plate 902 and the second clamping plate 15 clamp the surface mount diode that needs to be glued, the protective pad 10 can protect the surface mount diode that needs to be glued, avoiding the first clamping plate 902 and the second clamping plate 15 from clamping and damaging the surface mount diode that needs to be glued, achieving the effect of protecting the surface mount diode that needs to be glued.

[0033] As a technical optimization scheme of the present utility model, a rotating column 19 is threadedly connected to the inside of the second connecting rod 904, and the rear side of the rotating column 19 passes through the second connecting rod 904 and extends to the rear side of the second connecting rod 904.

[0034] In this embodiment: By holding the screwing block 8 and rotating the screwing block 8, the rotation of the screwing block 8 drives the rotation of the rotating column 19. Through the threaded connection between the rotating column 19 and the second connecting rod 904, when the rotating column 19 rotates, the second connecting rod 904 can be driven to move backward, achieving the effect of conveniently driving the movement of the second connecting rod 904.

[0035] As a technical optimization scheme of the present utility model, a bearing 18 is rotatably connected to the rear side of the rotating column 19. The rear side of the bearing 18 is fixedly connected to the front side of the support plate 5, and a screwing block 8 is fixedly connected to the front side of the rotating column 19.

[0036] In this embodiment: The rotating column 19 is rotatably connected to the support plate 5 through the bearing 18, enabling the rotating column 19 to rotate, achieving the effect of conveniently rotating the rotating column 19.

[0037] As a technical optimization scheme of the present utility model, a limiting block 11 is fixedly connected to the bottom of the support plate 5. A limiting groove 14 is formed inside the sliding plate 7, and the top of the limiting block 11 extends into the inside of the limiting groove 14. Support blocks 12 are fixedly connected to the four corners of the bottom of the support plate 5.

[0038] In this embodiment: By placing the support plate 5 on the top of the sliding plate 7, the limiting block 11 extends into the inside of the limiting groove 14. At this time, the limiting block 11 can limit the support plate 5 on the top of the sliding plate 7, achieving the effect of limiting the support plate 5 on the top of the sliding plate 7.

[0039] As a technical optimization scheme of the present utility model, two magnets 13 are inlaid inside the sliding plate 7, and the tops of the magnets 13 are magnetically attracted to the top of the support plate 5.

[0040] In this embodiment: Through the magnetic attraction between the magnet 13 and the support plate 5, the support plate 5 can be limited, preventing the support plate 5 from separating from the sliding plate 7, achieving the effect of preventing the support plate 5 from separating from the sliding plate 7.

[0041] As a technical optimization scheme of the present utility model, a fixing block 16 is fixedly connected to the front side of the second clamping plate 15, and the number of the fixing blocks 16 is several.

[0042] In this embodiment: The patch diodes that need to be brushed with glue are sequentially placed between two adjacent height blocks, and the fixing block 16 can separate the patch diodes that need to be brushed with glue, achieving the effect of separating the patch diodes that need to be brushed with glue.

[0043] Working principle: First, place the pallet 5 on a stable table. At this time, the support block 12 at the bottom of the pallet 5 will stably support the pallet 5. Then, place the surface mount diode to be glued on the top of the pallet 5, so that the back side of the surface mount diode to be glued contacts the protective pad 10 on the front side of the second clamping plate 15, and separate the surface mount diodes to be glued individually through the fixing blocks 16. After placing the surface mount diodes to be glued between adjacent fixing blocks 16, rotate the screwing block 8. The rotation of the screwing block 8 drives the rotating column 19 to rotate. Through the threaded connection between the rotating column 19 and the second connecting rod 904, the second connecting rod 904 can be driven to move backward when the rotating column 19 rotates. When the second connecting rod 904 moves backward, the first connecting rod 903 and the sliding bar 901 can be driven to move backward. The sliding bar 901 slides inside the sliding groove 17, enabling the sliding bar 901 to move. The movement of the sliding bar 901 drives the first clamping plate 902 to move backward, making the protective pad 10 contact the surface mount diode to be glued. At this time, the first clamping plate 902 and the second clamping plate 15 can clamp the surface mount diode to be glued. Then, place the pallet 5 on the top of the sliding plate 7, so that the limiting block 11 extends into the limiting groove 14. At this time, the limiting block 11 can limit the pallet 5 on the top of the sliding plate 7. At the same time, the magnet 13 will magnetically attract the pallet 5, thereby limiting the pallet 5 to prevent it from separating from the sliding plate 7. At this time, set the corresponding program for the surface mount diode automatic gluing machine, and then control the surface mount diode automatic gluing machine to work. At this time, the surface mount diodes to be glued on the top of the pallet 5 can be glued. By clamping and gluing a larger number of surface mount diodes to be glued with the larger-volume pallet 5, it can be avoided that when the surface mount diode automatic gluing machine glues the surface mount diodes to be glued, only a small number or a single surface mount diode to be glued can be placed on the top of the sliding plate 7. When gluing a large number of surface mount diodes to be glued, the efficiency is low, and there is no structure for limiting the surface mount diodes to be glued, resulting in the displacement of the surface mount diodes to be glued easily when the glue-brushing head 4 glues the surface mount diodes to be glued, affecting the gluing effect of the surface mount diodes to be glued and thus the use effect.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
