[0027] Embodiment

[0028] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:

[0029] An on-line adjustment device for glue coating uniformity includes a conveyor belt 1. A connecting plate 3 is arranged directly above the conveyor belt 1. A plurality of glue dripping and coating components 5 for leveling the glue on the surface of electronic components are arranged below the connecting plate 3. A glue coating driving component 4 for driving a plurality of glue dripping and coating components 5 to work is arranged on the connecting plate 3;

[0030] Among them, a height adjusting member 2 for driving the connecting plate 3 to lift is installed on the top of the connecting plate 3.

[0031] Specifically, please refer to Figure 2 , the height adjusting member 2 includes a first motor 21 and a longitudinal support rod 26. The output shaft of the first motor 21 is fixedly connected with a rotating disk 22 through a coupling.

A gear disk 25 is installed on the connecting rod 24. A tooth groove 27 is installed on the longitudinal support rod 26. The connecting rod 24 is meshed with the tooth groove 27 on the longitudinal support rod 26 through the gear disk 25. The bottom of the longitudinal support rod 26 is fixedly connected with the connecting plate 3.

[0032] Specifically, please refer to Figure 2 , a support plate 11 is installed on the top of the conveyor belt 1. A first support rod 12 and a second support rod 13 are installed on the support plate 11;

[0033] Among them, the first motor 21 is fixed on the surface of the support plate 11. One end of the first support rod 12 away from the support plate 11 is rotatably connected with the connecting rod 24. The longitudinal support rod 26 is slidably connected with the support plate 11 in a vertical direction through the second support rod 13.

[0034] In this embodiment: Start the first motor 21. The first motor 21 will drive the rotating disk 22 to rotate. The rotating disk 22 drives the connecting rod 24 to rotate up and down through the connecting block 23. Under the restriction of the first support rod 12, when one side of the connecting rod 24 moves downward, this side of the gear disk 25 will move upward. Then, under the restriction of the second support rod 13, the longitudinal support rod 26 will drive the connecting plate 3 to move upward until the glue dripping and coating component 5 is just slightly higher than the surface to be coated of the electronic component.

[0035] For details, please refer to Figure 3 The glue coating drive component 4 includes a second motor 41 and a plurality of driven wheels 44. A second belt 45 is provided between two adjacent driven wheels 44, and the two adjacent driven wheels 44 are connected through the second belt 45. A driving wheel 42 is fixedly connected to the top of the output shaft of the second motor 41. A first belt 43 is provided between the driving wheel 42 and the adjacent second belt 45. The driving wheel 42 is connected to the adjacent second belt 45 through the first belt 43. The plurality of driven wheels 44 are installed on adjacent glue coating components 5.

[0036] In this embodiment: the second motor 41 is started, and the second motor 41 drives the nearest driven wheel 44 to rotate through the driving wheel 42 and the first belt 43. Through multiple second belts 45, each driven wheel 44 can finally drive the rubber coating brush 54 to rotate continuously through the rotating rod 51, the positioning plate 52 and the coating plate 53. When the surface to be coated of the electronic component is located below the glue coating assembly 5, the height adjustment part 2 is started in reverse at this time to drive the multiple glue coating assemblies 5 to descend through the connecting plate 3 until they completely contact the surface to be coated of the electronic component.

[0037] For details, please refer to Figures 4-5 The glue coating assembly 5 includes a rotating rod 51, the top of which is fixed to the adjacent driven wheel 44, and the bottom of which is fixedly connected to a positioning plate 52. A coating plate 53 is provided at the bottom of the positioning plate 52, and a plurality of rubber blocks 55 are installed on the coating plate 53. The coating plate 53 is interference fit with the bottom of the positioning plate 52 through the plurality of rubber blocks 55, and a rubber coating brush 54 is installed at the bottom of the coating plate 53.

[0038] In this embodiment: when the rubber coating brush 54 needs to be replaced, it is only necessary to pull the coating disc 53 downwards, and the rubber clamp 55 only needs to be slightly deformed to release the connection between the coating disc 53 and the positioning disc 52. After replacement, the rubber clamp 55 can be re-inserted into the positioning disc 52 to continue working, and the operation is convenient and quick.

[0039] For details, please refer to Figure 6 A plurality of first springs 6 are installed at the bottom of the second motor 41, the bottoms of the plurality of first springs 6 are connected to the top of the connecting plate 3, and a second spring 7 is sleeved on the plurality of rotating rods 51, one end of the second spring 7 is connected to the surface of the rotating rod 51, and the other end of the second spring 7 is connected to the inner wall of the connecting plate 3.

[0040] In this embodiment: The flexible connections between the first spring 6 and the second motor 41, and between the second spring 7 and the rotating rod 51 can prevent the surface to be coated of the electronic component from coming into hard contact with the dispensing coating assembly 5, which may cause damage due to pressing. In such a case, it is possible to make the multiple dispensing coating assemblies 5 evenly apply all the glue on the surface to be coated of the electronic component, and adjust the height of the dispensing coating assembly 5 as needed.

[0041] Furthermore, the height adjusting member 2 is a servo motor that can adjust forward and reverse rotation.

[0042] The working principle and usage process of the present utility model: When the device is in use, first place the electronic component with glue dropped on the conveyor belt 1, and let the surface to be coated of the electronic component face upward and stand still. Subsequently, according to the height of the contact surface of the electronic component, start the first motor 21. The first motor 21 will drive the rotating disk 22 to rotate. The rotating disk 22 drives the connecting rod 24 to rotate up and down through the connecting block 23. Under the restriction of the first support rod 12, when one side of the connecting rod 24 moves downward, this side of the gear disk 25 will move upward. Then, under the restriction of the second support rod 13, the longitudinal support rod 26 drives the connecting plate 3 to move upward until the dispensing coating assembly 5 is just slightly higher than the surface to be coated of the electronic component.

[0043] Subsequently, start the second motor 41. The second motor 41 drives the nearest driven wheel 44 to rotate through the driving wheel 42 and the first belt 43. Through multiple second belts 45, each driven wheel 44 can drive the rubber coating brush 54 to continuously rotate through the rotating rod 51, the positioning disk 52, and the coating disk 53. When the surface to be coated of the electronic component is located below the dispensing coating assembly 5, at this time, reverse-start the height adjusting member 2, which drives the multiple dispensing coating assemblies 5 to descend through the connecting plate 3 until they completely contact the surface to be coated of the electronic component. The flexible connections between the first spring 6 and the second motor 41, and between the second spring 7 and the rotating rod 51 can prevent the surface to be coated of the electronic component from coming into hard contact with the dispensing coating assembly 5, which may cause damage due to pressing. In such a case, it is possible to make the multiple dispensing coating assemblies 5 evenly apply all the glue on the surface to be coated of the electronic component, and adjust the height of the dispensing coating assembly 5 as needed.

[0044] When it is necessary to replace the rubber coating brush 54, only need to pull down the coating disk 53. The rubber block 55 only needs to deform slightly to release the connection between the coating disk 53 and the positioning disk 52. After replacement, reinsert the rubber block 55 into the positioning disk 52 to continue working. The operation is convenient and fast.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
