Description

Technical Field

[0001] This invention relates to the field of crystal oscillator products, and more particularly to an integrated machine for disassembling, testing, and reeling crystal oscillator products. Background Technology

[0002] During the production of crystal oscillators, the equipment must be produced in a cleanroom. Each process step in the production of crystal oscillators requires a corresponding machine, which occupies a large cleanroom space. At the same time, the increase in operators will also increase the production management cost. On the other hand, each machine has an independent control system and power supply, making the process complicated and causing waste.

[0003] Currently, for crystal oscillator products that require re-tapping and testing after tape bonding, the process involves first pulling off the top tape of the wound tape and pouring out the material. Then, the poured-out material is placed in an electrical testing machine for testing. After the test is completed, the material is placed on a tray and then re-bonded on a TP machine.

[0004] The process involves manually pulling the material, transferring it to the testing equipment for reloading, positioning, and starting the test. Each step requires manual intervention, making the process cumbersome. Manual operation necessitates intermittent machine stops for material pulling and loading, preventing continuous production and reducing equipment utilization. Manual operation can also cause fluctuations in parameters such as tape tension and crystal oscillator orientation due to operational differences, affecting product performance consistency. Summary of the Invention

[0005] This invention provides a compact, all-in-one testing and tape-reeling machine that can complete the disassembly, testing, and tape-reeling of crystal oscillators on a single device. This machine is highly efficient, occupies a small area, has a high degree of automation, and produces products with good consistency. It solves the technical problems of existing technologies that require multiple devices, have a large footprint, high cost, and poor product performance consistency.

[0006] The above-mentioned technical problem of the present invention is solved by the following technical solution: a disassembly, testing, and reeling machine for crystal oscillators includes a workbench with a disassembly mechanism connected to it, a testing mechanism connected to it, and a reeling mechanism. The disassembly mechanism includes a disassembly bracket with a feeding track. One end of the feeding track has a reel roll, and the other end has a disassembly component that divides the reel into an upper and lower tape. The disassembled crystal oscillators are located at a pick-up station. The crystal oscillators are then transported from the pick-up station to the testing mechanism via a transmission mechanism. After testing, the crystal oscillators are transported to the reeling mechanism via the transmission mechanism. By integrating the disassembly, testing, and re-reeling mechanisms, all processes can be completed on a single machine. This results in a compact structure, small footprint, and good product performance consistency. After the disassembly mechanism removes the upper and lower tapes of the original crystal oscillator, the crystal oscillator is transported to the testing mechanism via the transmission mechanism. Qualified products are then transported back to the reeling mechanism via the transmission mechanism to complete the reeling process. This eliminates the need for machine downtime and material waiting, enabling continuous production and improving efficiency.

[0007] Preferably, the disassembly mechanism, testing mechanism, and tape-making mechanism are arranged in a U-shape. The transmission mechanism includes a transmission support with a suction nozzle track mounted on it. The length of the suction nozzle track is greater than the distance between the disassembly mechanism and the tape-making mechanism, and suction nozzles are mounted on the suction nozzle track. This U-shaped arrangement positions the transmission mechanism behind the testing mechanism, facilitating seamless flow between the three processes. The structure is compact. After the crystal oscillator is disassembled by the disassembly mechanism, it is directly placed onto the testing mechanism. Throughout the process, the suction nozzle holds the crystal oscillator until testing is complete. Then, the suction nozzle places the crystal oscillator onto a new tape in the tape-making mechanism for tape-making. The transmission mechanism completes the transport from the disassembled tape to the new tape, resulting in a short transport distance, a rational layout, and improved operability.

[0008] Preferably, the disassembly bracket has a portion of a feeding track on its inner side, and another portion of the feeding track is located on the upper surface of the disassembly bracket, feeding the disassembled tape to the disassembly component. The disassembly bracket also has an upper tape track; the disassembled upper tape exits from the disassembly component, passes through the upper tape track, and reaches the upper tape recycling point. A portion of the upper tape track is located above the feeding track. The feeding track located on the inner side of the disassembly bracket facilitates connection with the braiding roll, making efficient use of the space within the disassembly bracket and guiding the braiding direction. The braiding roll to be disassembled is transferred to the feeding track, and the other portion of the feeding track is located on the upper surface of the disassembly bracket, facilitating connection with the disassembly component for disassembly. After passing the disassembly component, the original braided tape is divided into an upper tape and a lower tape. The lower tape continues along the feeding track for recycling, while the upper tape passes through the upper tape return groove on the disassembly component, loops back above the feeding track, and passes through the guide wheels on the disassembly bracket, feeding the upper tape to the upper tape recycling point.

[0009] Preferably, the disassembly component of the disassembly bracket is a thin sheet hinged to the disassembly bracket. The thin sheet is located above one end of the tape feed track, and has a crystal oscillator groove and an upper tape return groove. The thin sheet can press down the tape, allowing it to move within the tape feed track. Simultaneously, the end of the thin sheet separates the upper and lower tapes, exposing the crystal oscillator. The crystal oscillator continues forward with the lower tape until it reaches the crystal oscillator groove, where a suction nozzle picks up the crystal oscillator and transports it to the testing mechanism. The lower and upper tapes are then retrieved along the track.

[0010] Preferably, a toggle gear is provided below the disassembly component of the disassembly bracket, and a toggle groove is provided on one side of the crystal oscillator slot of the disassembly component. The toggle groove is located above the belt feed track, and the toggle gear corresponds to the toggle groove. The toggle gear drives the lower belt to move, and the speed of the lower belt movement can be controlled to facilitate coordination with the subsequent suction nozzle movement.

[0011] Preferably, the testing mechanism includes a calibration structure and test probes. The test probes are located below the test plates, which are multiple in number, with a defective product box on one side. The nozzle picks up the crystal oscillator from the crystal slot and places it into the calibration structure for calibration. After calibration, the nozzle places the crystal oscillator back onto the test plates, selecting different test plates based on the crystal oscillator's specifications and model. After testing, qualified products are carried by the nozzle into the tape and reel mechanism, while unqualified products are placed into the defective product box. Throughout the testing process, the nozzle remains in contact with the crystal oscillator.

[0012] Preferably, the tape feeding mechanism includes a tape feeding track, a lower tape unloading roll at one end of the tape feeding track, a first CCD structure above the tape feeding track, an upper tape unloading structure behind the first CCD structure, an upper and lower tape bonding structure at the other end of the tape feeding track, a second CCD structure behind the upper and lower tape bonding structure, and a receiving structure behind the second CCD structure. The tested crystal oscillator is first placed on the lower tape, then the first CCD camera detects the correctness and orientation of the characters on the current material. Then the upper tape covers it, passes through a heating and sealing blade, reaches the second CCD camera for a second check, and finally is wound into a roll.

[0013] Preferably, the receiving structure includes receiving gears and receiving guide wheels arranged vertically, with the tape passing through the channel between the receiving gears and the receiving guide wheels, and then wrapped around the receiving wheel after passing through the receiving gears.

[0014] Preferably, the upper braiding tape unloading structure includes a mounting bracket, on which an upper braiding tape unloading roll is mounted. The upper braiding tape of the upper braiding tape unloading roll is guided to the upper braiding tape guide block by the upper braiding tape guide wheel. After passing through the guide hole on the upper braiding tape guide block, the upper braiding tape is fed to the braiding track and bonded to the lower braiding tape. Multiple upper braiding tape guide wheels are arranged at right angles.

[0015] Therefore, the integrated disassembly, testing, and reeling machine for crystal oscillators of the present invention has the following advantages: it integrates the disassembly and reeling of crystal oscillators, followed by testing, and then reeling again onto a single device, resulting in a small footprint, high degree of automation, improved efficiency, and good product consistency. The disassembly, testing, and reeling processes are arranged in a U-shape, with the transfer mechanism facilitating the transfer of products between each stage. The transfer mechanism is parallel to the testing mechanism, maximizing space utilization. Attached Figure Description

[0021] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example:

[0023] like Figure 1 and 2 As shown, a crystal oscillator product disassembly, testing, and reeling integrated machine includes a work platform 1, on which a reeling disassembly mechanism 4, a testing mechanism, and a reeling mechanism 2 are installed. The reeling disassembly mechanism 4, the testing mechanism, and the reeling mechanism 2 are arranged in a U-shape, and a transmission mechanism 3 is located above the testing mechanism, through which the crystal oscillator product is transferred between the various mechanisms.

[0024] like Figure 3 and 4As shown, the disassembly mechanism 4 includes a disassembly bracket 42, one end of which is fan-shaped, and a thin sheet 45 is mounted on the upper surface of the other end of the disassembly bracket 42. A toggle gear 50 is mounted below the thin sheet 45, and the position of the toggle gear 50 corresponds to the position of the side hole on the tape. Rotation of the toggle gear 50 drives the tape forward, and the toggle gear 50 is fixed to the disassembly bracket 42. A crystal oscillator slot 48 corresponding to the size of the crystal oscillator is formed on the thin sheet 45, and an upper tape return slot 49 is formed at the front end of the crystal oscillator slot 48. A toggle groove 47 is formed on the side of the crystal oscillator slot 48, and the toggle gear 50 is located below the toggle groove 47.

[0025] A tape feeding track 41 is provided on the disassembly bracket 42. One end of the tape feeding track 41 is connected to the tape reel 43, which is installed inside the fan-shaped portion of the disassembly bracket 42. The other end of the tape feeding track 41 is connected to the lower tape recovery reel. A portion of the tape feeding track 41 is located inside the disassembly bracket 42 for easy connection with the tape reel 43 to guide the tape to be disassembled. The other portion of the tape feeding track 41 is located on the upper surface of the disassembly bracket 42 for easy engagement with the sheet 45 on the disassembly bracket, facilitating the separation of the upper and lower tapes and the removal of the crystal oscillator. An upper tape track 44 is also arranged on the disassembly bracket 42, located above the tape feeding track 41. After being disassembled, the upper tape passes through the upper tape return groove and the upper tape track 44, and then winds onto the upper tape recovery wheel 46 via the upper tape guide wheel. The upper tape recovery wheel 46 is installed on the disassembly bracket 42.

[0026] After the tape is unwound, the suction nozzle 5 of the transfer mechanism, located perpendicular to the unwound mechanism, picks up the crystal oscillator and transports it. The suction nozzle 5 is mounted on a suction nozzle track 9, which is perpendicular to the unwound mechanism 4. The length of the suction nozzle track 9 is greater than the distance between the unwound mechanism 4 and the tape-making mechanism 2, and the suction nozzle track 9 is located above the test structure. The suction nozzle 5 transports the crystal oscillator between various processes. After the suction nozzle 5 picks up the crystal oscillator, it is placed in a calibration position. The four-way gripper 6 on the calibration position squeezes and calibrates the crystal oscillator on the suction nozzle. After calibration, the suction nozzle picks up the crystal oscillator and places it onto the test board 7. Probes are installed below the test board 7. There are multiple test boards 7; different test boards are selected according to the specifications and models of different crystal oscillators. Below the test board 7 are X and Y direction adjustment structures for adjusting the position of the test board. The suction nozzle places the crystal oscillator at the probe test position for pressure testing. When the test fails, the suction nozzle picks up the crystal oscillator and places it onto the defective product box 8 on one side of the test board.

[0027] like Figure 5As shown, qualified crystal oscillators are brought to the tape-making mechanism by the suction nozzle 5 for tape-making. The tape-making mechanism includes a tape-making track 22, at one end of which a lower tape-making unloading roll 21 is arranged. The lower tape-making unloading roll 21 is placed on a lower tape-making bracket 211 on the worktable. The lower tape-making unloading roll 21 is guided onto the tape-making track 22 by the lower tape-making guide wheel 212. A first CCD structure 26 is arranged above the tape-making track 22 and is fixed on a mounting bracket 23, which is fixed on the worktable 1. An upper tape-making unloading structure is provided behind the first CCD structure 26. The upper tape-making unloading structure includes an upper tape-making unloading roll 24 mounted on the mounting bracket 23. The upper tape of the upper tape-making unloading roll 24 is guided to the upper tape-making guide block 28 by the upper tape-making guide wheel 25. The multiple upper tape-making guide wheels are arranged at right angles. The upper braiding guide block 28 is located above the braiding channel 22. After passing through the guide hole on the upper braiding guide block 28, the upper braiding is fed onto the braiding track to bond with the lower braiding. The heated sealing knife 27 continues to advance the bonded upper and lower braiding along the braiding track. A second CCD structure 29 is arranged behind the upper and lower braiding bonding structure, and a take-up structure is provided behind the second CCD structure 29. The take-up structure includes a take-up gear 31 and a take-up guide wheel 30 arranged vertically. The braiding passes through the channel between the take-up gear 31 and the take-up guide wheel 30, and after passing through the take-up gear, it is wound around the take-up wheel 32.

[0028] In use, place the tape roll to be disassembled onto the disassembly bracket, and move the gear forward to advance the tape. The upper and lower tapes are separated by the thin plate. The upper tape passes through the upper tape return groove, is guided by the upper tape track, and is finally retrieved by the upper tape recovery wheel. The lower tape advances along the tape feeding channel and is exited from the rear of the thin plate. The crystal oscillator on the separated tape is exposed. The suction nozzle uses negative pressure to suck up the crystal oscillator and places it on the calibration four-jaw mechanism for calibration. After calibration, the suction nozzle sends the crystal oscillator to the test plate for a pressure probe test. After the test, qualified products are placed in the tape feeding mechanism by the suction nozzle, and unqualified products are placed in the defective product box. The lower tape of the tape feeding mechanism is fed onto the tape feeding track by the lower tape feeding roll. Through the rotation of the take-up gear, the lower tape moves forward to below the first CCD structure to check the correctness of the current material characters and the direction of orientation. After the check is completed, it continues to move forward. The upper tape feeding roll feeds the upper tape through the upper tape guide wheel to the guide hole on the upper tape guide block and merges with the lower tape. After being bonded by the heated sealing knife, it is checked again by the second CCD structure and then wound into a roll.
