[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 9 As shown, the present invention discloses an automatic LED strip adhesive applicator, comprising a machine base 1, on which a product feeding and applicating device 2 and a finished product receiving device 3 are provided; the product feeding and applicating device 2 includes a base 21, on which an LED strip feeding assembly, a double-sided adhesive feeding assembly, a product guiding and applicating assembly 27, and a finished product guiding and feeding assembly are provided; the LED strip feeding assembly includes correspondingly arranged LED strip feeding wheel group 22 and LED strip guiding wheel group 23; the double-sided adhesive feeding assembly includes a double-sided adhesive tray 24, a first guide wheel 25, and a second guide wheel 26 arranged sequentially; The product guiding and attaching assembly 27 includes an upper limit wheel 271, a lower limit wheel 272, an upper pressing wheel 273, and a lower pressing wheel 274. A product guiding channel is formed between the upper limit wheel 271 and the lower limit wheel 272; a product attaching and pressing channel is formed between the upper pressing wheel 273 and the lower pressing wheel 274. The LED light strip guide wheel assembly 23 and the second guide wheel 26 are respectively arranged corresponding to the product guiding channel, the product guiding channel is arranged corresponding to the product attaching and pressing channel, the product attaching and pressing channel is arranged corresponding to the finished product guiding and feeding assembly, and the finished product guiding and feeding assembly is arranged corresponding to the finished product receiving device 3. With this arrangement, the automatic LED light strip adhesive applicator can attach double-sided adhesive 5 to the back of the LED light strip 4, using automated operation to replace traditional manual operation, which improves work efficiency and saves labor.

[0033] The working principle of this utility model is as follows: The free end (back side facing up) of the LED light strip 4 is fed into the LED light strip feeding wheel group 22, and then guided by the LED light strip guide wheel group 23 before being fed into the product guide channel; at the same time, the free end (the side with the release film attached is facing up, and the adhesive side is facing down) of the double-sided adhesive 5 on the double-sided adhesive tray 24 is guided by the first guide wheel 25 and the second guide wheel 26 before being fed into the product guide channel, so that the double-sided adhesive 5 is attached to the back of the LED light strip 4. After being guided by the product guide channel, it is fed into the product bonding and pressing channel to press and attach the double-sided adhesive 5 to the back of the LED light strip 4. The finished product after bonding is fed into the finished product guiding feeding assembly, and finally the finished product is wound up by the finished product winding device 3.

[0034] Initially, the free end of the LED strip 4 needs to be manually passed through the LED strip feed roller group 22, the LED strip guide roller group 23, and the product guide attachment component 27 in sequence before being wound onto the finished product receiving device 3. The free end of the double-sided adhesive 5 also needs to be manually guided around the first guide roller 25 and the second guide roller 26 in sequence before being attached to the back of the LED strip 4. Then, together with the LED strip 4, it is passed through the product guide attachment component 27 and tightly attached. When the finished product receiving device 3 rotates to rewind, it pulls the LED strip 4 and the double-sided adhesive 5 to attach and rewind at the same time.

[0035] The product feeding and attaching device 2 and the finished product receiving device 3 are located on both sides of the machine base 1, making reasonable use of the installation space of the machine base 1. The finished product receiving device 3 is equipped with a power drive to pull the product. The upper limit wheel 3 271 and the lower limit wheel 3 272 are arranged vertically and correspondingly. The upper limit wheel 3 271 has a groove for limiting the double-sided adhesive 5, and the lower limit wheel 3 272 has a groove for limiting the LED light strip 4. The grooves of these two devices allow the edge of the double-sided adhesive 5 to be flush with the edge of the LED light strip 4. Edge alignment solves the problem of uneven edges that occurs with manual application; the distance between the upper limit roller 3 271 and the lower limit roller 3 272 can be pre-adjusted according to the product thickness; the upper pressure roller 273 and the lower pressure roller 274 are arranged vertically and vertically, and both the upper pressure roller 273 and the lower pressure roller 274 are also provided with grooves, which make the double-sided adhesive 5 and the LED light strip 4 press firmly and adhere; the distance between the upper pressure roller 273 and the lower pressure roller 274 can be pre-adjusted according to the product thickness.

[0036] Furthermore, the LED strip feeding wheel assembly 22 includes a left limiting wheel 221, a right limiting wheel 222, an upper limiting wheel 223, and a lower limiting wheel 224. An LED strip feeding channel is formed between the left limiting wheel 221, right limiting wheel 222, upper limiting wheel 223, and lower limiting wheel 224. The LED strip feeding channel is correspondingly arranged with the LED strip guide wheel assembly 23. With this arrangement, when the LED strip 4 is fed, it passes through the LED strip feeding channel and is fed into the LED strip guide wheel assembly 23.

[0037] The left limiting wheel 221 and the right limiting wheel 222 are arranged in a left-right correspondence. The distance between the left limiting wheel 221 and the right limiting wheel 222 can be pre-adjusted according to the width of the LED light strip 4. The upper limiting wheel 223 and the lower limiting wheel 224 are arranged in a vertical correspondence. The distance between the upper limiting wheel 223 and the lower limiting wheel 224 can be pre-adjusted according to the thickness of the LED light strip 4. This allows for the passage of LED light strips 4 with different widths and thicknesses. When the LED light strip 4 passes through the preset LED light strip feeding channel, the LED light strip 4 is limited by the LED light strip feeding channel and will not be misaligned, which facilitates subsequent processes of attachment.

[0038] Furthermore, the LED strip guide wheel assembly 23 includes an upper limit wheel 231 and a lower limit wheel 232, forming an LED strip guide channel between them. The LED strip feeding channel and the LED strip guide channel are correspondingly arranged, and the LED strip guide channel and the product guide channel are correspondingly arranged. With this arrangement, the LED strip 4, passing through the LED strip feeding channel, is fed into the LED strip guide channel and then guided through the LED strip guide channel to the product guide attachment assembly 27.

[0039] The upper limit wheel 231 and the lower limit wheel 232 are arranged in a vertically corresponding manner, and the distance between the upper limit wheel 231 and the lower limit wheel 232 can be adjusted in advance according to the thickness of the LED light strip 4; the lower limit wheel 232 is provided with a slot for limiting the LED light strip 4.

[0040] Furthermore, both the first guide wheel 25 and the second guide wheel 26 are formed with double-sided adhesive limiting grooves. This design allows the double-sided adhesive 5 to be limited by the double-sided adhesive limiting grooves, preventing the double-sided adhesive 5 from detaching or shifting.

[0041] The positions of the first guide wheel 25 and the second guide wheel 26 can be adjusted according to the actual position between the double-sided adhesive material tray 24 and the product guide attachment assembly 27; when the double-sided adhesive 5 is assembled, the side with the release film attached abuts and is limited on the first guide wheel 25 and the second guide wheel 26.

[0042] Furthermore, the finished product guiding and feeding assembly includes a finished product guide wheel 28 and a finished product pre-tightening wheel 29. The product attaching and pressing channel is correspondingly arranged with the finished product guide wheel 28, the finished product guide wheel 28 is correspondingly arranged with the finished product pre-tightening wheel 29, and the finished product pre-tightening wheel 29 is correspondingly arranged with the finished product receiving device 3. With this arrangement, the attached finished product is guided to the finished product receiving device 3 after passing through the finished product guide wheel 28 and the finished product pre-tightening wheel 29.

[0043] In non-working state (e.g.) Figure 1 , 2 As shown in Figure 3), the finished preload wheel 29 is located at the bottom, in the working state (as shown in Figure 3). Figure 9 As shown), the pre-tensioning wheel 29 presses the finished product on top of it, making the finished product more compact after winding and preventing it from becoming loose.

[0044] Furthermore, both the finished product guide wheel 28 and the finished product preload wheel 29 are formed with finished product guide grooves. This arrangement, through the grooves of these two components, serves to restrict the finished product, preventing it from detaching or shifting.

[0045] Furthermore, the pre-tensioning wheel 29 is adjustable in position between the finished product guide wheel 28 and the finished product take-up device 3. This arrangement allows the position of the pre-tensioning wheel 29 between the finished product guide wheel 28 and the finished product take-up device 3 to adjust the pre-tensioning force of the finished product during winding, according to actual needs.

[0046] Among them, the finished pre-tightening wheel 29 is mounted on one end of the base 21 near the finished guide wheel 28 via an adjusting rod.

[0047] Furthermore, the finished product receiving device 3 includes an "I"-shaped coil 31, a fixed base 32, a second motor 35, and a movable base 36; the fixed base 32 is fixed on the machine base 1, and the fixed base 32 is provided with an active clamping wheel 34; the movable base 36 is adjustablely positioned on the machine base 1, and the movable base 36 is provided with a driven clamping wheel 37; the "I"-shaped coil 31 is located between the active clamping wheel 34 and the driven clamping wheel 37; the second motor 35 is fixed on the machine base 1, and the second motor 35 drives the active clamping wheel 34 to rotate, so that the active clamping wheel 34 drives the "I"-shaped coil 31 to rotate.

[0048] The "I"-shaped coil 31 consists of a spool and circular baffles at both ends. The active clamping wheel 34 and the driven clamping wheel 37 are clamped on the circular baffles at both ends. When the active clamping wheel 34 is driven to rotate by the motor 35, the "I"-shaped coil 31 rotates. The driven clamping wheel 37 can be adjusted according to the width of the "I"-shaped coil 31. After the finished product is fully wound into the "I"-shaped coil 31, the entire "I"-shaped coil 31 is removed for packaging, similar to a cable coil. The output end of the motor 35 is connected to the active clamping wheel 34 by a synchronous belt drive.

[0049] Furthermore, the machine base 1 is equipped with a cylinder 38 and a slide rail 39. A slider 310 is slidably mounted on the slide rail 39. The upper end of the slider 310 is fixedly connected to the movable seat 36, and the lower end of the slider 310 is fixedly connected to the output end of the cylinder 38. With this configuration, when the "I"-shaped coil 31 is assembled, the cylinder 38 drives the slider 310 to move the movable seat 36 away from the fixed seat 32, thereby opening the installation space between the active clamping wheel 34 and the driven clamping wheel 37, facilitating the assembly of the "I"-shaped coil 31. After the "I"-shaped coil 31 is assembled, the cylinder 38 drives the slider 310 to move the movable seat 36 closer to the fixed seat 32, so that the active clamping wheel 34 and the driven clamping wheel 37 cooperate to clamp the take-up roller 31.

[0050] Furthermore, the machine base 1 is equipped with a finished product moving device 11, which includes a housing 12. The housing 12 has a sliding groove 13, and a sliding plate 14 is slidably disposed within the sliding groove 13. The first end of the sliding plate 14 is fixedly connected to the base 21. A lead screw is disposed within the housing 12, and the lead screw is threadedly connected to the second end of the sliding plate 14. The lead screw is driven to rotate by a motor 15. A travel limit component 16 is installed on the housing 12, and the travel limit component 16 is correspondingly disposed with the sliding plate 14. With this configuration, the motor 15 drives the lead screw (which is disposed within the housing and not shown in the figure) to rotate, causing the sliding plate 14 to move back and forth within the sliding groove 13, thereby driving the base 21 to move back and forth. During this process, the finished product can be spirally distributed and wound onto the "I"-shaped coil 31, resulting in a better winding effect.

[0051] When the finished product needs to be wound in a single row along the diameter direction, the motor 15 does not work, and the finished product is wound at the same position of the "I" shaped coil 31 during winding; the stroke limit component 16 can be adjusted on the housing 12 according to actual needs, and when the slide plate 14 moves to correspond to or touch the stroke limit component 16, the motor 15 drives in the reverse direction; the product feeding and attaching device 2 is slidably located on the top of the housing 12.
