Description

Technical Field

[0001] This utility model belongs to the field of carrier tape detection technology, and in particular relates to a high-speed carrier tape imaging inspection device. Background Technology

[0002] Carrier tape is a strip-shaped product used in electronic packaging. It has a specific thickness and features evenly distributed holes (also called pockets) along its length for holding electronic components and positioning holes for indexing. The carrier tape is used in conjunction with a cover tape (top sealing tape) to hold electronic components such as resistors, capacitors, transistors, and diodes within the pockets. The cover tape is then sealed on top of the carrier tape to form a closed package, protecting the electronic components from contamination and damage during transportation. During component placement, the cover tape is peeled off, and automated placement equipment uses the precise positioning of the carrier tape's indexing holes to sequentially remove the components from the pockets and place them onto the integrated circuit board (PCB). To protect the electronic components from electrostatic discharge (ESD) damage, carrier tape transport and inspection are crucial steps in semiconductor manufacturing and packaging processes. Traditional carrier tape transport systems typically use a single servo motor drive, which can easily lead to film wrinkles during transport, affecting inspection results. Furthermore, inconsistent light transmittance of the carrier tape can also negatively impact inspection results. To address these issues, this patent proposes an improved design for the carrier belt detection mechanism. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] In one embodiment of this utility model, such as Figures 1-2 As shown, a high-speed carrier belt imaging inspection device is provided, including a base 100, a mounting plate 200, a carrier belt conveying mechanism 300, and a detection mechanism 400. The mounting plate 200 is vertically mounted on the base 100. The carrier belt conveying mechanism 300 and the detection mechanism 400 are mounted on the mounting plate 200. The carrier belt conveying mechanism includes a feeding / receiving assembly 310 and a drive assembly 320. The feeding / receiving assembly includes a feeding tray 311 and a receiving tray 312, which are respectively disposed on opposite sides of the mounting plate 200. The detection mechanism 400 is disposed between the feeding tray 311 and the receiving tray 312. The drive assembly 320 is located on one side of the detection mechanism 400 and is used to drive the carrier belt from the feeding tray 311 to the receiving tray 312. Each segment of the carrier belt passes sequentially through the detection mechanism 400. In this embodiment, the main components of the device include the base 100, the mounting plate 200, the carrier belt conveying mechanism 300, and the detection mechanism 400. The base 100 provides a stable foundation, and the mounting plate 200 is vertically fixed to the base 100, providing support for other components. The carrier belt conveying mechanism 300 includes a feeding assembly and a drive assembly 320. The feeding tray 311 is located on one side of the mounting plate 200 and is used to hold the carrier belt to be conveyed. The receiving tray 312 is located on the other side of the mounting plate 200 and is used to collect the carrier belt that has been inspected and processed. The drive assembly 320 is located on one side of the inspection mechanism 400 and is responsible for driving the carrier belt from the feeding tray 311 to the receiving tray 312. During this process, the carrier belt will pass through the inspection mechanism 400 for inspection in sequence. The inspection mechanism 400 is located between the feeding tray 311 and the receiving tray 312 and is used to perform quality inspection on the passing carrier belt to ensure that the quality of the carrier belt meets the requirements. The drive assembly 320 moves the carrier belt on the feeding tray 311. The carrier belt passes through the detection mechanism 400 in sequence. The detection mechanism 400 performs quality inspection on the products in the carrier belt. The qualified carrier belt is finally moved to the receiving tray 312 for storage. The unqualified carrier belt may need to be further processed or recycled, thereby realizing the automatic conveying and quality inspection of the carrier belt.

[0026] Furthermore, the drive assembly 320 includes an upper drive member 330 and a lower drive member 340. The lower drive member 340 includes a lower drive gear 341 and a lower drive motor 342. The lower drive motor 342 is mounted on the mounting plate 200, and the lower drive gear 341 is located at the drive end of the lower drive motor 342. The lower drive motor 342 drives the lower drive gear 341 to rotate. The lower drive gear 341 is located near the feeding tray 311 and below the carrier belt, meshing with the carrier belt. The upper drive member 330 includes an upper drive gear 331, an upper drive motor 332, and a drive lifting mechanism 333. A lifting mechanism 333 is mounted on the mounting plate 200. An upper drive motor 332 is mounted on the drive end of the lifting mechanism. The lifting mechanism drives the upper drive motor 332 to rise or fall. An upper drive gear 331 is mounted on the drive end of the upper drive motor 332. The upper drive motor 332 drives the upper drive gear 331 to rotate. The upper drive gear 331 is located near the receiving tray 312 and above the carrier belt, meshing with the carrier belt. In this embodiment, the upper drive gear 331 and the lower drive gear 341 mesh with the upper and lower ends of the carrier belt index hole, respectively, so that both ends of the carrier belt are connected. With the synchronous rotation of the upper drive gear 331 and the lower drive gear 341, the carrier belt runs more smoothly. The lifting mechanism is used to lift the upper drive component 330, so that the upper drive gear 331 can better mesh with the carrier belt, facilitating the replacement of the carrier belt and ensuring smooth conveying of the carrier belt.

[0027] Furthermore, the drive assembly 320 also includes a lifting assembly 350, which is disposed on the mounting plate 200 and located at one end of the lower drive member 340. The lifting assembly 350 includes a lifting cylinder and a lifting roller. The lifting cylinder is used to drive the lifting roller to rise or fall, and the lifting roller is located below the carrier belt. In this embodiment, the lifting assembly 350 is used to lift the carrier belt, making the carrier belt bend and tighten, thereby eliminating wrinkles in the film and making it easier for the inspection mechanism 400 to perform photographic inspection. The light transmittance of the carrier belt itself will affect the inspection effect of the lower inspection mechanism 400, so bending and tightening the carrier belt enhances its light transmittance.

[0028] Furthermore, the detection mechanism 400 includes an upper CCD imaging component 410 and a lower CCD imaging component 420 disposed on the mounting plate 200. The upper CCD imaging component 410 is located above the carrier tape, and the lower CCD imaging component 420 is located below the carrier tape. In this embodiment, both the upper and lower ends of the carrier tape are photographed for detection.

[0029] Furthermore, the detection mechanism 400 also includes a lifting mechanism 430, which is mounted on the mounting plate 200. The lower CCD imaging component 420 is mounted on the lifting end of the lifting mechanism 430, and the lifting mechanism 430 is used to drive the lower CCD imaging component 420 to rise or fall. In this embodiment, the lifting mechanism 430 is used to drive the lower CCD imaging component 420 to rise or fall. For carrier tapes of different thicknesses, the product depth within the carrier tape is inconsistent. To ensure the accuracy of carrier tape detection, the distance between the lower CCD imaging component 420 and the carrier tape is changed to improve detection accuracy.

[0030] Furthermore, it also includes an NG marking mechanism 500, which is mounted on the mounting plate 200 and located between the detection mechanism 400 and the receiving tray 312. The NG marking mechanism 500 is used to mark NG products detected by the detection mechanism 400. In this embodiment, when the detection mechanism 400 detects a good product, the equipment does not stop and continues to detect the next one. When the detection mechanism 400 detects a defective product, the NG marking mechanism 500 on the equipment will affix a red label next to the defective product for easy identification by the operator.

[0031] Furthermore, the NG marking mechanism 500 includes a support frame 510, a marking machine 520, and a detection sensor 530. The support frame 510 is mounted on a support plate, the marking machine 520 is located on the support frame 510 and is used to mark the carrier tape, and the detection sensor 530 is mounted on the support frame 510 and located at the rear end of the marking machine 520, used to detect the label marked by the marking machine 520. In this embodiment, when the detection mechanism 400 detects a defective product, the NG marking mechanism 500 on the equipment will affix a red label next to the defective product, and at the same time, the detection sensor 530 will confirm whether the label is missing, making it easier for the operator to identify.

[0032] Furthermore, both the feeding tray 311 and the receiving tray 312 are equipped with servo motors 313, which are used to drive the feeding tray 311 and the receiving tray 312 to rotate. In this embodiment, when the drive assembly 320 drives the carrier belt to move, the servo motors 313 drive the feeding tray 311 and the receiving tray 312 to rotate synchronously, which facilitates smooth feeding and receiving of the carrier belt.

[0033] Furthermore, it also includes a rewinding mechanism 600, which includes a rewind unloading reel 610 and a rewind take-up reel 620. The rewind unloading reel 610 and the rewind take-up reel 620 are respectively disposed on both sides of the mounting plate 200 for winding the carrier tape. In this embodiment, after the inspection is completed, the rewinding mechanism 600 can restore the inspected reel to its original position.

[0034] Furthermore, a cleaning mechanism 700 is also included. The cleaning mechanism 700 includes a plurality of brushes 710, each brush 710 being located between the feed tray 311 and the take-up tray 312, or between the rewind feed tray 610 and the rewind take-up tray 620, for cleaning the carrier belt. In this embodiment, the brushes 710 clean the carrier belt to prevent dust from adhering to it.

[0035] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
