[0037] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment proposes a glue brushing auxiliary buffer mechanism, such as Figure 1 As shown, there is a glue discharging unit 10 for mixing glue and applying glue, a first floating unit 20 for buffering and floating adjustment of the glue applying head 11 in the first direction, and a second floating unit 30 for buffering and floating adjustment of the glue applying head 11 in the second direction and the third direction. The glue discharging unit 10 and the second floating unit 30 are connected with the stand 22 and are respectively disposed at the front and rear sides of the first floating unit 20. The glue discharging unit 10 is provided with the glue applying head 11; the first floating unit 20 is provided with the stand 22 for fixing the glue applying head 11 and a plurality of first buffers 21 for buffering the glue applying head 11 along the first direction; the second floating unit 30 is provided with the second buffer 31 for buffering along the second direction and the rotating shaft 33 for rotating along the third direction, and the second buffer 32 is arranged perpendicularly and crosswise with the rotating shaft 33.

[0039] The vertical direction of the stand 22 is the first direction, the direction perpendicular to the plane of the stand 22 is the second direction, and the direction perpendicular to the first direction and the second direction is the third direction. Figure 2-4 Example directions shown.

[0040] The first buffer 21 can make the glue brush head 11 float and adjust along the vertical height direction; the second buffer 31 can make the glue brush head 11 float and adjust along the horizontal left and right direction; accordingly, the rotating shaft 33 can make the glue brush head 11 rotate along the axial direction perpendicular to the left and right direction in the horizontal plane to rotate the glue brush head 11, and the first buffer 21 and / or the second buffer 31 can make adaptive floating adjustment to the glue brush head 11. Thus, the glue brush head 11 can be buffered from all directions or angles to ensure the tightness of the direct contact between the glue brush head 11 and the resin board, so that the brush clamp 11 can completely and continuously brush the colloid onto the surface of the resin board in any position to complete the glue brushing work.

[0041] like Figure 2 As shown, the glue discharging unit 10 also includes a plurality of groups of single glue tubes 12, a mixing glue tube 13 connected to the single glue tubes 12, and a motor 14 for driving the flow of glue. Among them, there are at least two single glue tubes 12, and each single glue tube 12 is equipped with a motor 14 for driving the flow of colloid. The two motors 14 independently control the colloids in the two single glue tubes 12 to flow downward along the first direction, and the two kinds of colloids are alternately mixed in the mixing glue tube 13, and then the glue is brushed onto the surface of the resin board through the glue brushing head 11. Furthermore, the single glue tube 12 and the mixing glue tube 13 are both arranged along the first direction, that is, the vertical direction, and the single glue tube 12 and the motor 14 are both connected to the upper section of the stand 22; the mixing glue tube 13 and the glue brushing head 11 are both connected to the lower section of the stand 22.

[0042] Furthermore, a limiting plate 15 arranged along the second direction is provided below the glue brush head 11, and a long hole is provided on the limiting plate 15 for the glue brush head 11 to pass through. The limiting plate 15 can be directly attached to the resin plate without hindering the operation of the glue brush head 11, and can also improve the uniformity and continuity of the glue discharge of the glue brush head 11.

[0043] like Figure 3 As shown, the first floating unit 20 also includes a first auxiliary plate 23 and a second auxiliary plate 24 which are arranged on the side of the vertical frame 22 away from the glue discharging unit 10, and the first auxiliary plate 23 is located above the second auxiliary plate 24 and is spaced apart, and the first auxiliary plate 23 is located on the second auxiliary plate 24 and is connected to the upper frame and the lower frame in the vertical frame 22 through the fixing blocks 25 respectively.

[0044] Preferably, two separately arranged optical axes 27 are further configured between the first auxiliary plate 23 and the vertical plate 22. The optical axes 27 are arranged along the first direction for positioning the glue brushing track. In order to ensure the accuracy and safety of the glue brushing head 11, the optical axes 27 are located on both sides of the glue brushing head 11, that is, the glue brushing head 11 is located between the two optical axes 27 and arranged in the same column along the third direction.

[0045] Furthermore, the upper and lower ends of the first buffer 21 are connected to the fixed block 25 disposed between the first auxiliary plate 23 and the stand 22, and between the second auxiliary plate 24 and the stand 22 through bearings 26. There are two first buffers 21, which are also disposed on both sides of the rubber brush head 11 along the second direction, and the first buffer 21 is coaxially arranged with the optical axis 27 along the first direction and the third direction, and the first buffer 21 is sleeved outside the optical axis 27 to ensure that the optical axis 27 works without interference. Among them, the bearing 26 is a linear bearing.

[0046] Furthermore, the stand 22 includes an upper frame and a lower frame, wherein the upper end of the upper frame is connected to the first auxiliary plate 23 through a connecting plate, and the lower end thereof is connected to a fixing block 25 connected to the second auxiliary plate 24. The connection position between the upper frame and the lower frame is a stepped structure, and the lower frame is convex to the plane of the lower frame. Since the upper frame is connected to two motors 14 and two single rubber hoses 12, and the lower frame is only connected to the brush intersection 11, the width of the upper frame is greater than the width of the lower frame.

[0047] The optical axis 27 and the linear bearing 26 are matched and a first buffer member 21 is sleeved on the optical axis 27, so that the optical axis 27 can increase an upward elastic force along the first direction to reduce the weight of the entire glue discharging unit 10, so that the upper limit mechanism of the glue brush head 11 is reduced when it contacts the resin plate (omitted in the figure), thereby reducing the resistance of the glue brush head 11 during movement and improving production efficiency.

[0048] like Figure 4 As shown, the second floating unit 30 also includes a fixing plate 32 for fixing the second buffer 31. In this embodiment, the fixing plate 32 is a square structure, and a second buffer 31 is arranged at each corner thereof, so that the floating force at the four corners of the fixing plate 32 is uniform. The rotating shaft 33 is arranged at the center position of the fixing plate 32 through a fixing groove, and a connecting piece is arranged on the side of the rotating shaft 33 close to the stand 22, and is hinged to the stand 22 through the connecting piece. The rubber brush head 11 can rotate along its axis through the rotating shaft 33, that is, rotate along the third direction, so that the rubber brush head 11 can perform rotational buffering in the third direction to increase its relative contact surface with the resin plate.

[0049] In this embodiment, the number of the second buffer members 31 is greater than the number of the first buffer members 21. Along the first direction, the motor 14, the two single rubber hoses 12 and the rubber brush head 11 are all connected to the stand 22 along the first direction, and only the first buffer members 21 arranged symmetrically on both sides thereof can be adjusted along the first direction to achieve balance. As for the buffer adjustment member along the second direction, since the fixed plate 32 is connected to the stand 22 only through the rotating shaft 33, the second buffer members 31 arranged diagonally are also required to perform balance adjustment. Therefore, the number of the second buffer members 31 for buffering the rubber brush head 11 in the second direction is greater than the number of the first buffer members 21 for buffering the rubber brush head 11 in the first direction.

[0050] In order to prevent the second buffer member 31 from floating too much in the second direction, two limit rods 34 are provided on the fixed plate 32 in the same direction as the second buffer member 31. The two limit rods 34 are arranged on the upper and lower sides of the rotating shaft 33, and their length is less than the length of the second buffer member 31.

[0051] By placing two second buffer members 31 which are horizontally arranged, that is, arranged along the second direction, on the upper and lower sides of the rotating shaft 33, the glue brush head 11 can be adjusted to a position horizontally arranged with the resin plate, so that the glue brush head 11 can be swung left and right along the second direction with only a small force, ensuring that when there is left and right unevenness on the upper end surface of the resin plate in the second direction, the limit of the glue brush head 11 can also perfectly fit the contact with the resin plate, thereby improving the stability, uniformity and continuity of the glue output of the glue brush head 11.

[0052] In this embodiment, the first buffer member 21 and the second buffer member 31 are both springs.

[0053] A glue brushing machine is equipped with the auxiliary buffer mechanism as described above.

[0054] The glue brushing auxiliary buffer mechanism designed by the present application has a simple structure and is easy to control. It can make the glue brush head contact the resin plate adaptively, which can not only prevent the glue brush head from being blocked by glue, but also perform floating buffering on the upper and lower and left and right sides of the glue brush head to improve its flexibility in laminating with the resin plate, timely adjust the stability of the contact between the glue brush head and the resin plate, and ensure the uniformity and continuity of the glue discharge from the glue brush head. The present application also proposes a glue brushing machine provided with the auxiliary buffer mechanism.

[0055] The above detailed description of the embodiments of the present application is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent coverage of the present application.
