Description

Technical Field

[0001] This invention relates to the field of adhesive tearing and feeding equipment, and in particular to an automatic adhesive tearing and feeding device. Background Technology

[0002] In the electronics manufacturing industry, processed circuit boards are usually bound to fixtures with adhesive tape to ensure stability during processing. After processing, the adhesive tape must be removed to separate the circuit board from the fixture for recycling.

[0003] Traditional methods rely heavily on manual adhesive removal, which is inefficient, labor-intensive, and prone to damaging circuit board surfaces or leaving adhesive residue due to improper force control, affecting product yield. Furthermore, manual separation of circuit boards from fixtures can lead to sorting chaos and delayed fixture retrieval, making it unsuitable for mass production. Existing semi-automatic adhesive removal equipment suffers from poor adaptability, unidirectional adhesive removal, incomplete removal, and poor coordination between processes. It also lacks automated fixture recycling, resulting in insufficient production continuity and high production costs. Summary of the Invention

The tape tearing mechanism 50 is connected to the moving gripping mechanism 70 and is used to pick up the marking sticker 13 from the film supply mechanism 60 and apply it to the outside of the fixing tape 15 between the processing circuit board 11 and the fixing fixture 12. After the marking sticker 13 and the fixing tape 15 are firmly attached, the fixing tape 15 is peeled off from the processing circuit board 11 and the fixing fixture 12 by tearing the marking sticker 13. The film supply mechanism 60 is used to unwind and rewind the protective film 14 of the marking sticker 13. The moving gripping mechanism 70 is used to grip the processing circuit board 11 and the fixing fixture 12 respectively and transfer them to the circuit board unloading mechanism 30 and the fixture recycling mechanism 40 respectively. During operation, the feeding and conveying mechanism 20 moves the fixing fixture 12, which is loaded with the processed circuit board 11 at the previous station, to the adhesive peeling station; the moving gripping mechanism 70 drives the tape peeling mechanism 50 to move to the film supply mechanism 60, picks up the gripping end of the marking sticker 13 on the protective film 14, and attaches the adhesive end of the marking sticker 13 to one side of the fixing tape 15; after the marking sticker 13 and the fixing tape 15 are completely adhered, the moving gripping component drives the tape peeling component to peel off the marking sticker 13, thereby peeling off the fixing tape 15; after all the fixing tape 15 on the four sides of the processed circuit board 11 is peeled off, the moving gripping component grips the processed circuit board 11 and the fixing fixture 12 respectively, transfers the processed circuit board 11 to the circuit board unloading mechanism 30 to complete the finished product unloading, and transfers the fixing fixture 12 to the fixture recycling mechanism 40 to complete the fixture recycling, thus completing a single adhesive peeling and unloading operation.

[0022] Specifically, through multi-mechanism collaborative design, the entire process of automatic feeding of the processing circuit board 11 and the fixing fixture 12, automatic removal of the fixing tape 15, and separation and recycling of finished products and fixtures is fully automated, completely replacing manual operation and greatly improving production efficiency; the adhesive peeling method of the marking sticker 13 avoids direct contact with the circuit board and avoids damage, ensuring product yield; the division of labor among the mechanisms is clear and the connection is smooth, reducing operation downtime, adapting to the needs of mass production, and at the same time realizing the recycling of fixtures, reducing production costs.

[0023] like Figure 2 As shown, the feeding and conveying mechanism 20 includes a first conveying track 21, a first conveying belt 22, a first conveying drive motor 23, a first track gauge adjustment device 24, and a lifting and rotating device 80. The first conveying track 21 consists of two parallel tracks. The first conveying belt 22 is wound around the inner side of the first conveying track 21 to carry and convey the processed circuit board 11 and the fixing fixture 12. The output end of the first conveying drive motor 23 is connected to the first conveying belt 22 to drive the first conveying belt 22 to rotate cyclically to convey the processed circuit board 11 and the fixing fixture 12. The first track gauge adjustment device 24 is connected to the two first conveying tracks 21 and is used to adjust the distance between the two first conveying tracks 21.

[0036] Specifically, the X-axis and Z-axis linear modules, in conjunction with the gantry mounting bracket 713, enable precise multi-directional movement, covering the equipment's operating area with high movement accuracy and rapid response. The first gripping device 72 and the second gripping device 73 employ vacuum suction cups in conjunction with lifting slide cylinders.

[0037] The working principle of this invention is as follows: The feeding conveyor 20 and the circuit board unloading mechanism 30 adjust the track spacing through the track gauge adjustment device to match the size of the fixture and the finished board. The film supply mechanism 60 adjusts the film supply height and presets the conveying tension of the protective film 14 to ensure stable film supply. The feeding conveyor 20 sends the fixed fixture 12 loaded with the processed circuit board 11 to the adhesive peeling station. After it is in place, the lifting and rotating device 80 starts to lift the fixture and the circuit board so that they are separated from the conveyor belt, providing working space for adhesive peeling. At the same time, the film supply mechanism 60 continuously feeds the protective film 14 of the marking sticker 13 through the unwinding and traction device 63. After the clamping and positioning device 90 fixes the film material, the tape peeling mechanism 50, driven by the moving gripping mechanism 70, accurately picks up the marking sticker 13 on the protective film 14. Then, the visual positioning module 53 of the tape peeling mechanism 50 locks the position of the fixed tape 15, aligns the adhesive end of the marking sticker 13 with the fixed tape 15 and applies it, and then rolls and presses it with the pressing pulley to ensure a firm adhesion. Next, the moving gripping mechanism 70 drives the grippers to tear the marking sticker 13 along the peeling direction, simultaneously peeling the fixing tape 15 from between the circuit board and the fixture. The peeled tape is then separated from the grippers by the adhesive of the adhesive separation auxiliary net 59. After peeling the tape from the opposite sides, the lifting and rotating device 80 drives the fixture and circuit board to rotate 90°, and the tape peeling mechanism 50 rotates synchronously to adapt, repeating the application, pressing, and peeling actions to complete the peeling of the tape from the other two sides. After peeling, the two gripping devices of the moving gripping mechanism 70 respectively adsorb the circuit board and the fixing fixture 12: the circuit board is transferred to the unloading mechanism, which then transports it to the subsequent process; the fixing fixture 12 is transferred to the fixture recycling mechanism 40 to achieve fixture recycling. Throughout the process, the film supply mechanism 60 continuously unwinds the marking sticker 13 and the protective film 14 and rewinds it after peeling. All mechanisms work together to automatically complete the peeling, separation, unloading, and recycling operations.
