Description

Technical Field

[0001] This utility model relates to the field of chip carrier tape detection technology, and in particular to a chip carrier tape positioning hole detection device. Background Technology

[0002] Chip carrier tape is a type of carrier tape. Carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with cover tape to store semiconductors in the pockets of the carrier tape. The cover tape is then sealed on top of the carrier tape to form a closed package, which is used to protect electronic components from contamination and damage during transportation. Positioning hole inspection is required during the production of carrier tape.

[0003] The utility model patent with publication number CN218066287U in the prior art proposes a chip carrier tape positioning hole detection device, which can quickly and timely detect the size problem of the carrier tape, and at the same time perform full inspection of the positioning holes on the carrier tape. It can also promptly remind the staff so that the staff can confirm the size of the product and adjust the equipment in time, thus avoiding the problem of batch scrapping of carrier tapes.

[0004] However, it lacks the ability to flexibly adjust the detection structure, and the adaptability of the detection structure is poor. When facing chip carrier tapes with different apertures and positions, it is necessary to replace the detection device with a different size. The operation is not convenient, the device is not flexible, and wear problems easily occur between the ceramic needle and the carrier tape during the detection process, which can easily damage the carrier tape. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a chip carrier positioning hole detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a chip carrier positioning hole detection device, including a device body, which contains a worktable, a laser detector and a photoelectric receiver. A conveyor is provided on the worktable. The laser detector is located on the upper end of the conveyor and a mounting base is fixed on the top of the laser detector. The photoelectric receiver is located on the lower end of the conveyor and corresponds to the laser detector. A drive component is connected to the rear end of the mounting base and the photoelectric receiver. An adjustment component is provided at the bottom of the mounting base. An alarm is connected to the outer end of the photoelectric receiver.

[0008] The drive assembly includes a vertical slide rail fixed to the upper end of the worktable, on which a first slider and a second slider are slidably mounted, and telescopic rods are respectively connected to the outer sides of the first slider and the second slider.

[0009] Preferably, the adjustment assembly includes an adjustment rod fixed to the bottom of the mounting base, and a plurality of movable blocks are slidably mounted on the adjustment rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a drive assembly, a vertical slide rail, a first slider, a second slider, a fixed plate, a telescopic rod, a guide seat, and a guide rod. The first and second sliders drive two sets of telescopic rods to move up and down, and the two sets of telescopic rods drive the laser detector and photodetector to move back and forth, thereby enabling omnidirectional movement and adjustment of the laser detector and photodetector.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 4, the chip carrier positioning hole detection device provided in this embodiment includes a device body 1. The device body 1 includes a worktable 2, a laser detector 5 and a photoelectric receiver 6. A conveyor frame 3 is provided on the worktable 2. The laser detector 5 is located on the upper end of the conveyor frame 3 and a mounting base 4 is fixed on the top of the laser detector 5. The photoelectric receiver 6 is located on the lower end of the conveyor frame 3 and corresponds to the laser detector 5. A drive component 7 is connected to the rear end of the mounting base 4 and the photoelectric receiver 6. An adjustment component 8 is provided at the bottom of the mounting base 4. An alarm 9 is connected to the outer end of the photoelectric receiver 6.

[0026] In this embodiment, the drive assembly 7 includes a vertical slide rail 71 fixed to the upper end of the worktable 2. A first slider 72 and a second slider 73 are slidably mounted on the vertical slide rail 71. Telescopic rods 75 are respectively connected to the outer sides of the first slider 72 and the second slider 73. Fixing plates 74 are respectively fixed to the sides of the first slider 72 and the second slider 73. The two sets of telescopic rods 75 are respectively mounted on the fixing plates 74. The upper telescopic rod 75 is fixed to the mounting base 4, and the lower telescopic rod 75 is fixed to the photoelectric receiver 6. A guide seat 76 is fixed to the outer side of the telescopic rod 75. A guide rod 77 is movably inserted through the guide seat 76. The upper guide rod 77 is fixed to the mounting base 4, and the lower guide rod 77 is fixed to the photoelectric receiver 6. The first slider 72 and the second slider 73 drive the two sets of telescopic rods 75 to move up and down. The two sets of telescopic rods 75 drive the laser detector 5 and the photoelectric receiver 6 to move back and forth, thereby realizing the omnidirectional movement and adjustment of the laser detector 5 and the photoelectric receiver 6. This facilitates adaptation to more working environments, facilitates the detection of chip carriers with different hole positions, and is simple and convenient to operate, improving the flexibility of the device.

[0027] In this embodiment, the adjustment component 8 includes an adjustment rod 81 fixed to the bottom of the mounting base 4. Several moving blocks 82 are slidably mounted on the adjustment rod 81. Adjustment holes 83 are provided on the moving blocks 82. Adjustment bolts 84 are screwed into the adjustment holes 83 and the inner side of the adjustment bolts 84 abuts against the adjustment rod 81. Scale lines 85 are provided on the outer wall of the adjustment rod 81. The moving blocks 82 are respectively fixed to the upper end of the laser detectors 5. The laser detectors 5 are moved at the lower end of the adjustment rod 81 by the moving blocks 82. They are locked and fixed by the adjustment holes 83 and the adjustment bolts 84. The locking position is precisely controlled by the scale lines 85, thereby enabling the lateral position adjustment of multiple sets of laser detectors 5. This facilitates changing the spacing between the laser detectors 5 and adapting to chip carriers with different hole spacing designs. In conjunction with the drive component 7, the device compatibility is further improved.

[0028] The working principle and process of this utility model are as follows: During use, the chip carrier tape can be passed through the conveyor frame 3. The first slider 72 and the second slider 73 respectively drive the two sets of telescopic rods 75 to move up and down. The two sets of telescopic rods 75 respectively drive the laser detector 5 and the photodetector 6 to move back and forth, so that the laser detector 5 is positioned above the carrier tape hole and the photodetector 6 is positioned below the carrier tape hole. The laser detector 5 and the photodetector 6 work together to complete the hole positioning detection of the carrier tape. When dealing with carrier tapes of different sizes or with different hole positions, the positions of the laser detector 5 and the photodetector 6 can be adjusted using the telescopic rods 75. The moving block 82 drives the laser detector 5 to move at the lower end of the adjusting rod 81, and it is locked and fixed by the adjusting hole 83 and the adjusting bolt 84. This changes the spacing between the laser detectors 5 and, in conjunction with the drive assembly 7, completes the adaptation with the chip carrier tape hole.
