[0002] As an innovative product in modern lighting technology, flexible lamp strips have been widely used in indoor and outdoor decorative lighting, advertising signs, home atmosphere creation and other fields due to their flexible and changeable shapes, energy-saving and environment-friendly characteristics and easy installation and maintenance advantages. Flexible lamp strips are usually composed of LED light sources, circuit boards, transparent protective layers and insulating materials, can be bent along any curve without affecting their light-emitting effect, provide unlimited creative space for designers, and greatly enrich people's living environment. Users can easily realize personalized lighting layout through simple cutting and connection, and meet diversified lighting needs.

[0003] In the production process of flexible lamp strips, in order to facilitate subsequent installation and use, a layer of double-sided tape or self-adhesive tape is usually pasted on the back of the lamp strip to enhance the adhesion of the lamp strip to the installation surface and ensure its stability and durability in various application scenarios. This step is usually carried out after the lamp strip is assembled, that is, the non-light-emitting surface of the lamp strip is uniformly coated or pasted with special tape material.

[0004] However, there is a significant problem in the current process of pasting tape on the lamp strip: after the lamp strip is pasted with the tape, if the winding or arrangement is not timely and orderly, the lamp strip is scattered on the ground or is randomly bundled together. This processing method not only occupies a large amount of production space, but more importantly, the lamp strip is prone to bending without proper protection, especially in the part where the tape and the lamp strip are adhered, increasing the risk of adhesive falling off, thereby affecting the overall firmness and service life of the lamp strip.

[0022] Embodiment: A back rubber coating device for flexible lamp strip production, as shown in Figures 1-5As shown, it includes the rubber machine 1, the main frame 2, the first mounting frame 3, the fastener 4, the limiting plug rod 5, the support 6, the collection sleeve 11, the bidirectional screw rod 7, the fixed disc 8, the motor 9, the guide rod 10 and the compression assembly 12, the rubber machine 1 is provided with the main frame 2 on the front side, the first mounting frame 3 is slidably connected to the right part of the front end of the main frame 2, the limiting plug rod 5 is slidably connected to the connection between the main frame 2 and the first mounting frame 3, the first mounting frame 3 is rotatably connected with the fastener 4, the main frame 2 is slidably connected with two guide rods 10 on the left part of the front end, the guide rods 10 are jointly connected with the fixed disc 8 on the left side, the motor 9 is installed on the left side of the fixed disc 8, the main frame 2 is threadedly connected with the bidirectional screw rod 7 on the left part of the front end, the bidirectional screw rod 7 can reciprocate on the main frame 2 when rotating in one direction, the output shaft of the motor 9 is inserted into the left end of the bidirectional screw rod 7 and is spline-connected with the bidirectional screw rod 7, the support 6 is connected to the right end of the bidirectional screw rod 7, the collection sleeve 11 is sleeved on the support 6, the fastener 4 is inserted into the support 6 in an interference fit, the support 6 and the fastener 4 are both provided with a circular plate, the length of the circular rod in the middle of the support 6 is less than the length of the collection sleeve 11, and the main frame 2 is provided with the compression assembly 12 for compressing the rubber belt and the light belt in the middle.

[0023] As Figure 1 and Figure 5 shown, the compression assembly 12 includes the second mounting frame 121, the positioning roller 122, the compression roller 123, the sliding frame 124 and the compression spring 125, the second mounting frame 121 is connected in the middle of the main frame 2, the positioning roller 122 is rotatably connected to the bottom of the second mounting frame 121, the sliding frame 124 is slidably connected to the top of the second mounting frame 121, the compression roller 123 is rotatably connected to the bottom of the sliding frame 124, the compression spring 125 is sleeved on the sliding frame 124, the top of the compression spring 125 is connected with the second mounting frame 121, the bottom is connected with the sliding frame 124, and the gap between the compression roller 123 and the positioning roller 122 is less than the sum of the thicknesses of the light belt and the rubber belt.

[0024] After the lamp strip and the adhesive tape pass through the laminating machine 1, they are compressed by the compression roller 123, and further compressed by the compression assembly 12, and then wound on the collection sleeve 11. When the collection sleeve 11 is replaced, the staff needs to pull out the limiting rod 5, and then remove the first mounting frame 3 and pull out the fastener 4 together. Then, the collection sleeve 11 is pushed onto the support 6, or the collection sleeve 11 with the collected lamp strip is removed, and an empty collection sleeve 11 is replaced. After the replacement is completed, the fastener 4 is inserted. During the insertion of the fastener 4, the fastener 4 and the round plate of the support 6 squeeze the collection sleeve 11, and the fastener 4 is stably connected with the support 6, so as to clamp the collection sleeve 11. At this time, the first mounting frame 3 is also inserted into the main frame 2, and after the limiting rod 5 is inserted, the first mounting frame 3 is fixed on the main frame 2. Then, the motor 9 is started, and the motor 9 drives the bidirectional screw rod 7 to rotate. The bidirectional screw rod 7 slides on the main frame 2 which is threadedly connected with the bidirectional screw rod 7, so as to drive the fixed disc 8 and the guide rod 10 to slide. The guide rod 10 slides in the main frame 2, and the motor 9 moves with the fixed disc 8. The motor 9 moves back and forth on the main frame 2 through the bidirectional screw rod 7. The bidirectional screw rod 7 not only drives the support 6 to rotate, but also drives the support 6 to move left and right, so that the lamp strip can be uniformly wound on the collection sleeve 11. After one collection sleeve 11 is completed, the collection sleeve 11 is replaced according to the above steps.

[0025] When the lamp strip and the adhesive tape pass through the compression assembly 12, the compression roller 123 and the positioning roller 122 jointly act on the lamp strip. The position of the sliding frame 124 and the compression roller 123 is kept stable by the elastic force of the compression spring 125, so as to ensure that the distance between the two can adapt to lamp strips and adhesive tapes of different thicknesses. When the lamp strip passes through the compression roller 123 and the positioning roller 122, the lamp strip and the adhesive tape can be further compressed, so that the connection is more stable. After passing through the positioning roller 122, the lamp strip always remains in the middle position. The collection sleeve 11 moves left and right to collect the lamp strip, further reducing the possibility of bending and folding of the lamp strip, and protecting the production quality of the lamp strip.

[0026] As shown in Figure 5 , it also includes foam pads 13. The compression roller 123 is connected with a plurality of foam pads 13. The foam pads 13 have high softness, so that when the compression roller 123 and the positioning roller 122 squeeze the adhesive tape and the lamp strip, the compression effect of the compression roller 123 can be optimized, and the connection of the lamp strip and the adhesive tape is more stable.

[0027] As shown in Figure 3As shown, it also includes a rubber ring 14, which is sleeved on the support 6, and increases the diameter of the round rod of the support 6, and makes the connection between the collecting sleeve 11 and the support frame more stable, so that when the support 6 rotates, the collecting sleeve 11 can further ensure that it rotates with the support 6.

[0028] As shown, it also includes a rubber ring 14, which is sleeved on the support 6, and increases the diameter of the round rod of the support 6, and makes the connection between the collecting sleeve 11 and the support frame more stable, so that when the support 6 rotates, the collecting sleeve 11 can further ensure that it rotates with the support 6. Figure 2 As shown, it also includes a pulling rope 15, one end of which is connected with the limiting plug rod 5, and the other end is connected with the main frame 2, when the collecting sleeve 11 is replaced and the limiting part is removed, the pulling rope 15 can hang the limiting part on the main frame 2, so as to prevent the limiting part from being lost, and after the replacement of the collecting sleeve 11 is completed, the limiting part is convenient to take.

[0029] As shown, it also includes a rubber ring 14, which is sleeved on the support 6, and increases the diameter of the round rod of the support 6, and makes the connection between the collecting sleeve 11 and the support frame more stable, so that when the support 6 rotates, the collecting sleeve 11 can further ensure that it rotates with the support 6. Figure 1 As shown, it also includes a placing frame 16, which is connected with the side of the main frame 2, and can place the empty collecting sleeve 11 or the collected lamp strip, so as to facilitate the unified treatment of the lamp strip.

[0030] In work, the lamp strip and the adhesive tape are firstly subjected to preliminary adhesion by the adhesive taping machine 1, and then enter the further compression area composed of the compression assembly 12. The positioning roller 122 in the compression assembly 12 cooperates with the compression roller 123, and the soft foam pad 13 on the compression roller 123 is used to apply uniform pressure on the lamp strip and the adhesive tape, so as to ensure that they are tightly connected, and the compression spring 125 keeps the gap between the compression roller 123 and the positioning roller 122, which can adapt to lamp strips and adhesive tapes with different thicknesses. In this process, the lamp strip is centrally guided by the positioning roller 122, so as to ensure the neatness of the subsequent collection. After compression, the lamp strip and the adhesive tape combination is wound on the collecting sleeve 11, which is stably connected with the support 6 through the fastener 4. The circular plate structure of the fastener 4 and the support 6 clamps the collecting sleeve 11 during insertion, and the rubber ring 14 on the support 6 enhances the friction with the collecting sleeve 11, so as to ensure the stability of the collection process. When it is necessary to replace the collecting sleeve 11, the staff first pulls out the limiting plug rod 5 and prevents it from being lost by using the connected pulling rope 15, then pulls out the fastener 4 and the first mounting frame 3, replaces the new collecting sleeve 11, and re-installs the fastener 4 and the first mounting frame 3, and the limiting plug rod 5 is inserted again to fix the first mounting frame 3. After the motor 9 is started, the double-way screw rod 7 is driven to move left and right on the main frame 2 through the spline connection, and the double-way screw rod 7 simultaneously drives the support 6 and the collecting sleeve 11 to move, so as to realize the uniform collection of the lamp strip. The placing frame 16 on the side of the main frame 2 provides space for storing the empty collecting sleeve 11 and temporarily placing the collected lamp strip, so as to facilitate the continuity of production and management.

[0031] The above embodiment is only a preferred embodiment of the present application, and is not used to limit the scope of the present application, so that equivalent changes made according to the content described in the claims of the present application should be included in the scope of the claims of the present application.
