Description

Technical Field

[0001] This utility model relates to an assembly device for a sealing strip of an electric bicycle seat, and more particularly to an automatic feeding device for the sealing strip. Background Technology

[0002] To improve the sealing between the electric bicycle seat and the saddle and prevent rainwater from entering the storage box, a sealing groove is provided on the seat, and a sealing strip is installed in the sealing groove. The sealing strip is used to press tightly onto the saddle.

[0003] Existing sealing strips are all manually pressed in, which is inefficient, labor-intensive, and costly. To reduce costs, automatic pressing is adopted. However, since the sealing strips are extruded and then rolled into rolls, the existing feeding device places the rolls onto the rolling shaft, and then the pressing device automatically pulls out the sealing strips. This method requires the pressing device to provide a large pressure to extract the sealing strips. The pressing device is sometimes controlled by a robotic arm, which requires high power from the robotic arm, increasing its cost. Secondly, since the sealing strips are made of rubber, the friction between them is large, which further increases the force required to extract the sealing strips, and may even cause the sealing strips to get tangled, preventing normal feeding.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figures 1 to 8 As shown, an automatic sealing strip feeding device includes a sealing strip feeding device 11, a sealing strip delivery device 12, and a sealing strip detection device 13. The sealing strip feeding device 11 is used to store coiled sealing strips. The sealing strip delivery device 12 is disposed above one side of the sealing strip feeding device 11 and is used to deliver the sealing strip. The sealing strip detection device 13 is mounted on the sealing strip delivery device 12 and is used to control the sealing strip delivery device 12 and the sealing strip feeding device 11. When the sealing strip delivery device 12 delivers the sealing strip, the sealing strip feeding device 11 rotates so that the sealing strip enters from below the sealing strip delivery device 12.

[0027] The sealing strip feeding device 11 is used to store and rotate the sealing strip so that it enters from below the sealing strip feeding device 12, reducing the twisting of the sealing strip and the force required by the sealing strip feeding device 12 to pull the sealing strip, ensuring smooth feeding and preventing the sealing strip from getting stuck in the sealing strip feeding device 11. When the rear sealing strip pressing device is working, the sealing strip between the sealing strip pressing device and the sealing strip detection device 13 will be in a straightened state. The sealing strip can trigger the sealing strip detection device 13, which sends a start signal to the sealing strip feeding device 11 and the sealing strip feeding device 12. The sealing strip feeding device 11 and the sealing strip feeding device 12 then start feeding, realizing automatic control of feeding and stopping.

[0028] like Figures 1 to 3 As shown, the sealing strip feeding device 11 includes a sealing strip feeding cylinder 111, a sealing strip rotating device 112, and a sealing strip storage cylinder 113. The sealing strip rotating device 112 is installed at the bottom of the sealing strip feeding cylinder 111 and connected to the sealing strip storage cylinder 113. The sealing strip storage cylinder 113 is movably located inside the sealing strip feeding cylinder 111. The sealing strip rotating device 112 drives the sealing strip storage cylinder 113 to rotate. The sealing strip feeding cylinder 111 protects the internal sealing strip storage cylinder 113, improving safety. Specifically, the sealing strip rotating device 112 includes a first hollow rotating platform 1121 and a first rotating disk 1122. The first hollow rotating platform 1121 is an existing mature product and will not be described in detail here. The first hollow rotating platform 1121 is installed at the bottom of the sealing strip feeding cylinder 111, and the top turntable is connected to the first rotating disk 1122. The top of the first rotating disk 1122 is equipped with a sealing strip storage cylinder 113. The sealing strip storage cylinder 113 is a conical cylinder, that is, the top opening is large and the bottom is small, which avoids the sealing strip getting stuck in the sealing strip storage cylinder 113 and also facilitates the insertion of the sealing strip.

[0029] To prevent the sealing strip from hardening due to low ambient temperature, the sealing strip feeding device 11 also includes a heating element 114. The heating element 114 is installed inside the sealing strip feeding cylinder 111, located above the sealing strip storage cylinder 113. The heating element 114 is used to heat the sealing strip, making it soft and facilitating feeding and pressing. The heating element 114 can be an electric heating tube, electric heating wire, etc.

[0030] like Figures 4 to 8As shown, the sealing strip feeding device 12 includes a sealing strip feeding rod 129, a sealing strip feeding seat 121, a sealing strip feeding motor 122, a sealing strip active feeding roller 123, and a sealing strip driven feeding roller 124. One end of the sealing strip feeding rod 129 is fixed to the top of the sealing strip feeding cylinder 111, and the other end is connected to the sealing strip feeding seat 121. The sealing strip feeding seat 121 has a sealing strip inlet 1211 and a sealing strip outlet 1212 symmetrically arranged on both sides. The sealing strip feeding seat 121 has a sealing strip feeding cavity 1213 inside, which communicates with the sealing strip inlet 1211 and the sealing strip outlet 1212. A sealing strip feeding motor 122 is installed on one side of the sealing strip feeding seat 121 and connected to the sealing strip active feeding roller 123. The sealing strip active feeding roller 123 is located inside the sealing strip feeding chamber 1213. The sealing strip active feeding roller 123 is provided with an annular first feeding groove 1231. The first feeding groove 1231 matches the sealing strip and is used to control the direction of the sealing strip so that the sealing strip is fed in a set manner, which facilitates subsequent pressing. The first feeding groove 1231 can also increase the distance between the sealing strip and the sealing strip. The contact area is increased, thereby increasing the friction. The driven feeding roller 124 and the active feeding roller 123 of the sealing strip are arranged opposite each other, and the driven feeding roller 124 is rotatably installed in the sealing strip feeding cavity 1213. The sealing strip is located between the active feeding roller 123 and the driven feeding roller 124. The active feeding roller 123 and the driven feeding roller 124 pull the sealing strip with the friction between themselves and the sealing strip, so that the sealing strip is sent out from the sealing strip storage cylinder 113. The sealing strip delivery device 12 solves the problem that the sealing strip pressing device requires a high level of skill from the robotic arm. As a result, the robotic arm only needs to drive the sealing strip pressing device to press the density strip into the sealing groove of the seat cushion, which greatly reduces the force on the robotic arm, reduces the cost of the robotic arm, and simplifies the control of the robotic arm.

[0031] In order to further increase the friction between the active feeding roller 123 and the sealing strip, the outer circular surface of the active feeding roller 123 is provided with a number of first feeding teeth 1232. The first feeding teeth 1232 are also located on both sides of the first feeding groove 1231. The first feeding teeth 1232 can increase the friction between the active feeding roller 123 and the sealing strip.

[0032] To facilitate the adjustment of the friction between the sealing strip active feeding roller 123 and the sealing strip driven feeding roller 124 and the sealing strip, the sealing strip feeding device 12 further includes a friction adjustment device. The friction adjustment device is connected to the sealing strip driven feeding roller 124 and is used to adjust the distance between the sealing strip driven feeding roller 124 and the sealing strip active feeding roller 123, so as to achieve the adjustment of the friction with the sealing strip. Specifically, the friction adjustment device includes a tensioning shaft 125, a tensioning seat 126, and a tensioning screw. The tensioning shaft 125 is rotatably connected to the driven feeding roller 124 of the sealing strip, and its two ends are movably inserted into the first lifting groove 1214 at the bottom of the sealing strip feeding seat 121. The first lifting groove 1214 communicates with the sealing strip feeding chamber 1213. The tensioning seat 126 is symmetrically installed on both sides of the sealing strip feeding seat 121. The tensioning screw is movably inserted into the tensioning seat 126 and is threadedly connected to both ends of the tensioning shaft 125. Rotating the tensioning screw can adjust the distance between the driven feeding roller 124 and the active feeding roller 123 of the sealing strip, thereby realizing the adjustment of the friction between the active feeding roller 123 and the driven feeding roller 124 of the sealing strip and the sealing strip.

[0033] The sealing strip detection device 13 includes a sealing strip detection plate 131 and a micro switch 132. The sealing strip detection plate 131 is fixed on the sealing strip feeding seat 121 and connected to the micro switch 132. The micro switch 132 is also located on one side of the sealing strip outlet 1212. In the free state, the sealing strip bends downward due to gravity, and the micro switch 132 is in the closed state. When the sealing strip pressing device works, the sealing strip is straightened by the sealing strip, and the sealing strip pushes the micro switch 132, putting the micro switch 132 into the conducting state. The sealing strip feeding device 11 and the sealing strip delivery device 12 start to deliver the sealing strip. When the sealing strip pressing device stops pressing the sealing strip, the sealing strip leaves the micro switch 132 again, and the sealing strip feeding device 11 and the sealing strip delivery device 12 stop. The sealing strip detection device 13 realizes automatic feeding.

[0034] The sealing strip is fed out by the sealing strip feeding device 11 and the sealing strip delivery device 12, which effectively avoids the sealing strip getting tangled, makes the sealing strip feeding smooth, ensures the normal operation of the sealing strip pressing device, enables continuous operation, reduces the requirements on the robotic arm, reduces costs, and makes the control of the robotic arm simpler.
