[0002] In electronic products or some industrial applications, there are often magnetic rings or other ring-shaped products that need to paste an insulating adhesive on the inner ring surface. However, because one side of the insulating adhesive is sticky and the inner ring surface is inconvenient to operate, it is very difficult to achieve automatic adhesive pasting. Currently, the insulating adhesive is pasted manually, resulting in low efficiency. To achieve automatic adhesive pasting, it is very important to automatically paste the tape on the inner ring surface of the ring-shaped product.

[0003] The present invention is based on the above problems. Summary of the Invention

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] As Figures 1 to 4 shown, an inner - ring tape - sticking device includes a machine table 10. A clamping device 2 for clamping the workpiece 11 located at the tape - sticking station, a tape - clamping device 3 for conveying and clamping the tape 12, a tape - cutting device 5 for cutting the tape 12, and a tape - sticking device 4 for attaching the tape 12 to the inner - ring surface of the workpiece 11 are provided on the machine table 10.

[0025] When the present invention works, the workpiece 11 is placed at the tape - sticking station, and the clamping device 2 clamps the workpiece 11 to prevent the workpiece 11 from moving or rotating when sticking the tape 12. The tape - sticking device 4 winds the tape 12 held by the tape - clamping device 3 around its own outer wall. Then, the tape - cutting device 5 cuts the tape 12. The tape - sticking device 4 extends into the inner ring of the workpiece 11 and attaches the tape 12 wound around it to the inner - ring surface of the workpiece 11, thus completing the process of automatic tape - sticking. The structure of the present invention is simple, the tape - sticking is fast, the tape - sticking effect is good, the qualified rate is high, the production cost is low, and the degree of automation of the automatic tape - sticking process is greatly improved.

[0026] The tape sticking device 4 includes a tape sticking head 40, a second driving mechanism 42 for driving the tape sticking head 40 to telescopically enter and exit the inner ring of the workpiece 11, a third driving mechanism 43 for driving the tape sticking head 40 to rotate to wind the tape 12 around the outer wall of the tape sticking head 40, and a fourth driving mechanism 44 for driving the tape sticking head 40 to radially expand in the inner ring of the workpiece 11 so that the tape 12 surrounding the outer wall of the tape sticking head 40 adheres to the inner ring surface of the workpiece 11.

[0027] In this embodiment, when the tape sticking device 4 works, the fourth driving mechanism 44 drives the tape sticking head 40 to radially close so that the tape sticking head 40 clamps the free end of the tape 12 clamped by the tape clamping device 3. Then, the third driving mechanism 43 drives the tape sticking head 40 to rotate by a certain angle to wind the tape 12 around the outer wall of the tape sticking head 40. Then, the tape cutting device 5 cuts off the tape 12 between the tape clamping device 3 and the tape sticking head 40. Then, the second driving mechanism 42 drives the tape sticking head to extend into the inner ring of the workpiece 11. Then, the fourth driving mechanism 44 drives the tape sticking head 40 to radially expand to stick the tape 12 wound around the tape sticking head 40 to the inner ring surface of the workpiece 11. In order to make the sticking effect better, the third driving mechanism 43 drives the tape sticking head 40 to rotate in the reverse direction by a certain angle so that the tape 12 completely adheres to the inner ring surface of the workpiece 11. After the sticking is completed, the second driving mechanism 42 drives the tape sticking head 40 to withdraw from the inner ring of the workpiece 11. The structure of this embodiment is simpler, the tape sticking efficiency is higher, the tape sticking effect is better, and the degree of automation is higher.

[0029] The fourth opening and closing drive 441 drives the left tape sticking head 401 and the right tape sticking head 402 to move away from each other to open the tape sticking head 40. After the free end of the tape 12 extends between the left tape sticking head 401 and the right tape sticking head 402, the fourth opening and closing drive 441 drives the left tape sticking head 401 and the right tape sticking head 402 to move closer to each other to close the tape sticking head 40 and clamp the free end of the tape 12, facilitating the winding of the tape 12 when the tape sticking head 40 rotates.

[0030] The opposite surfaces of the left tape sticking head 401 and the right tape sticking head 402 are respectively concave surfaces so that a hollow cylinder is formed after the left tape sticking head 401 and the right tape sticking head 402 are combined.

[0031] In this embodiment, the free end of the tape 12 is clamped between the opposite surfaces of the left tape sticking head 401 and the right tape sticking head 402. The concave opposite surfaces can reduce the contact area with the adhesive surface of the tape 12, facilitating the smooth detachment of the clamped tape 12 from the tape sticking head 40 when it adheres to the inner ring of the workpiece 11.

The motor drives the fourth driving mechanism 44 and the tape - sticking head 40 to rotate through a belt transmission assembly. The fourth opening - closing drive 441 is a parallel pneumatic finger, and the parallel pneumatic finger drives the tape - sticking head 40 to open and close. The first driving mechanism 41, the second driving mechanism 42, the third driving mechanism 43, and the fourth driving mechanism 44 are all electrically connected to the control system, and the control system controls the automatic execution of the actions between each mechanism.

[0040] When the pressing mechanism 21 presses the workpiece 11, its output end and the first stopper 20 form a gluing station matching the shape of the workpiece 11.
