[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a light strip pressing plate mechanism, including a base plate 2 and a conveyor belt 1 for transporting light strips. The conveyor belt 1 is fixedly installed on the top of the base plate 2. The top of the base plate 2 is provided with a correction component to prevent the light strip from deviating. The base plate 2 can support the conveyor belt 1, which is beneficial to the operation of the conveyor belt 1. At the same time, the conveyor belt 1 can transport multiple light strips at the same time, which is beneficial to the simultaneous application of glue to multiple light strips and improves the processing efficiency of light strips.

[0023] The correction assembly includes a correction frame 6 and a correction wheel 10. The correction frame 6 is fixedly installed on the top of the base plate 2, and the correction frame 6 has multiple transmission slots for the movement of the light strips on the side near the conveyor belt 1. The correction frame 6 is located at the transmission end of the conveyor belt 1. After the multiple light strips are transmitted through the conveyor belt 1, they move into the inner cavity of the multiple transmission slots, which helps to limit the movement trajectory of the multiple light strips and prevent the movement trajectory of the light strips from deviating.

[0024] Multiple transmission slots and the correction frame 6 are provided with connecting slots on both sides. A support rod 9 is provided on one side of the correction frame 6. Two symmetrically installed correction wheels 10 are provided in the inner cavity of each of the multiple transmission slots. When the light strip moves into the inner cavity of the transmission slot, the top two sides of the light strip are respectively in contact with the outer wall of the two correction wheels 10 inside the transmission slot, and the bottom of the light strip is in contact with the bottom of the inner cavity of the transmission slot. When the correction wheels 10 rotate, the correction wheels 10 apply pressure to the light strip along the tangential direction of contact with the light strip, so that the light strip can move in a straight line. At the same time, with the cooperation of the correction wheels 10 and the bottom of the inner cavity of the transmission slot, the movement trajectory of the light strip is limited again to prevent the light strip from deviating during movement and reduce the adverse effects on the application of adhesive to the light strip.

[0025] One end of the alignment wheel 10 has a through hole that matches the support rod 9. One end of the support rod 9 passes through multiple connecting slots and through holes and extends to the other side of the alignment frame 6. A drive motor for rotating the support rod 9 is elastically installed on one side of the alignment frame 6. When the drive motor is started, the support rod 9 rotates. The support rod 9 rotates with the power output end of the drive motor, causing multiple alignment wheels 10 to rotate synchronously. At this time, the light strips inside multiple transmission slots move simultaneously.

[0026] A support plate 4 is fixedly installed on the side of the correction frame 6 near the drive motor. The support plate 4 is located directly below the drive motor, and a reset spring 5 connected to the bottom of the drive motor is fixedly installed on the top of the support plate 4. The reset spring 5 can apply a continuous pressure to the drive motor in the direction of moving closer to the base plate 2, and simultaneously apply pressure to multiple correction wheels 10, thereby improving the tightness of the fit between the outer wall of the correction wheel 10 and the top two sides of the light strip.

[0027] The bottom of the inner cavity of the multiple transmission slots and the top of the transmission belt 1 are flush with each other, which can ensure that the light strip remains horizontal after entering the transmission slot, thus improving the smoothness of the light strip movement.

[0028] In a preferred embodiment, two transmission bearings 13 are fixedly installed on the outer wall of the support rod 9. The correction frame 6 is located between the two transmission bearings 13. A connecting plate 12 is fixedly installed on the outer wall of each of the two transmission bearings 13. A U-shaped frame 7 is elastically installed at the end of the connecting plate 12 away from the transmission bearings 13. A hydraulic cylinder 8 for moving the U-shaped frame 7 up and down is fixedly installed on the top of the correction frame 6. The U-shaped frame 7 can connect the two connecting plates 12 and support the support rod 9. After the hydraulic cylinder 8 is activated, the U-shaped frame 7 moves up and down with the power output end of the hydraulic cylinder 8. At the same time, the two connecting plates 12 and the support rod 9 move up and down with the U-shaped frame 7. At this time, the support rod 9 moves up and down along the inside of the connecting groove, thereby accurately controlling the distance between the bottom of the correction wheel 10 and the bottom of the inner cavity of the transmission groove, which is beneficial for the passage of light strips of different thicknesses inside the transmission groove.

[0029] Furthermore, the connecting plate 12 is rotatably connected to the outer wall of the support rod 9 through the transmission bearing 13, which supports the support rod 9 while reducing the resistance generated by the rotation of the support rod 9 and improving the smoothness of the rotation of the support rod 9.

[0030] Both connecting plates 12 have receiving slots on their tops. One end of the U-shaped frame 7 is inserted into the inner cavity of the receiving slot. A top pressure spring 11 connected to the end of the U-shaped frame 7 is fixedly installed on the inner wall of the receiving slot away from its opening. The top pressure spring 11 can apply a continuous thrust to the U-shaped frame 7 in the direction away from the connecting plate 12. When the hydraulic cylinder 8 is activated and the U-shaped frame 7 is moved closer to the light strip, the top pressure spring 11 is compressed and applies downward pressure to the top of the connecting plate 12. At this time, the support rod 9 moves down, so that the outer wall of the correction wheel 10 is softly connected to the outer wall of the top of the light strip, preventing damage to the outer wall of the light strip and protecting the light strip.

[0031] The top of the inner cavity of the transmission groove is provided with a plug hole that communicates with the top of the correction frame 6. A dispensing tube 3 for fixing the lamp beads is fixedly installed in the inner cavity of the plug hole. Adhesive liquid is provided through the inside of multiple dispensing tubes 3. The adhesive liquid drips onto the outside of the lamp beads, which is beneficial to the adhesion between the lamp beads and the light strip.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
