Description

Technical Field

[0001] The utility model relates to the technical field of LED carrier tapes, and more specifically, to a carrier tape distance measuring device for LED carrier tape feeding. Background Technique

[0002] An LED carrier tape is a plastic carrier used to carry and store electronic components such as LEDs. It is used in conjunction with a cover tape (upper sealing tape) to carry and store electronic components such as LEDs in the pockets of the carrier tape, and a closed packaging is formed by sealing the cover tape above the carrier tape. This packaging method aims to protect electronic components from pollution and damage during transportation and facilitate subsequent automated mounting operations.

[0003] Currently, in the tape forming production process of LED carrier tapes, a feeding device is required to convey the carrier tape, and an LED lamp bead is placed in the carrier tape in cooperation with a feeding device. When the existing feeding device conveys the carrier tape, it is not convenient to position the carrier tape, which affects the stability of placing the LED lamp beads. In view of this, we propose a carrier tape distance measuring device for LED carrier tape feeding. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a carrier tape distance measuring device for LED carrier tape feeding, so as to solve the technical problem that when the existing feeding device conveys the carrier tape, it is not convenient to position the carrier tape, which affects the stability of placing the LED lamp beads.

[0005] To solve the above technical problem, the utility model provides the following technical solution: A carrier tape distance measuring device for LED carrier tape feeding, including a processing table with a feeding component detachably installed on one side of the top;

[0006] The feeding component includes a supporting table with a side plate fixedly arranged on one side. One end side of the side plate is detachably installed with a supporting bracket. A carrier tape body is placed in the supporting bracket. Positioning holes are equidistantly arranged on both sides of the upper end surface of the carrier tape body. On the other end side of the side plate, positioning component A is symmetrically and detachably installed. The positioning component A includes a fixing plate with a convex block arranged on the top. One side of the convex block is detachably installed with a flap. One side of the flap is rotatably installed with a driven wheel. On the outer edge surface of the driven wheel, positioning convex points B that are movably abutted in the positioning holes are arranged in an annular array structure. On one side of the upper end surface of the supporting table, positioning component B is detachably installed;

[0007] The positioning component B includes a motor A detachably installed on the supporting table. The motor A is connected with a belt transmission mechanism. One end of the belt transmission mechanism is connected with a connecting shaft. Symmetrically configured on the outer edge surface of the connecting shaft are driving wheels. Annularly arrayed on the outer edge surface of the driving wheels are positioning bumps A that are movably abutted in the positioning holes.

[0008] In the present utility model, by designing the positioning component A and the positioning component B, during the process of feeding the carrier tape body, the movement of the carrier tape body will drive the driven wheel to rotate, so that the positioning bump B is movably inserted into the positioning hole. The passive positioning of the carrier tape body during the feeding process is realized through the cooperation of the positioning bump B and the positioning hole. The driving wheel can be driven to rotate by the motor A and the belt transmission mechanism, so that the positioning bump A is movably inserted into the positioning hole. The active positioning of the carrier tape body during the feeding process is realized through the cooperation of the positioning bump A and the positioning hole. Thus, the accurate positioning of the carrier tape body during the feeding process is realized by combining the active and passive positioning methods, which is beneficial to ensuring the stability of the placement of the LED lamp beads.

[0009] Preferably, the lengths of the positioning bump A and the positioning bump B that movably extend into the positioning hole are both one-half of the depth of the positioning hole, and rounded corner structures are formed at the edge positions of the ends of the positioning bump A and the positioning bump B. A positioning wheel is configured on one side of the driving wheel, and the outer edge surface of the positioning wheel abuts against the bottom of the carrier tape body.

[0010] Preferably, the positioning component B further includes a rectangular vertical plate fixedly arranged at a corner of the upper end surface of the supporting table. A photoelectric ranging sensor for measuring the single-feed distance of the carrier tape body is detachably installed on the upper end surface of the side plate.

[0011] Preferably, the belt transmission mechanism includes a pulley A fixedly installed on the motor shaft of the motor A. A rotating shaft is rotatably installed inside the rectangular vertical plate. A pulley B is fixedly installed on the outer edge surface of one end of the rotating shaft. A transmission belt is tensioned between the pulley B and the pulley A. One end of the connecting shaft is fixedly connected to the pulley B.

[0012] Preferably, a circular shaft rotatably connected to the convex block is arranged inside the flap. Bolts are threadedly fitted and installed on one side of the fixing plate and the flap respectively. The bolts are arranged in a staggered manner, and a tension spring is connected between the outer edge surfaces of the bolt rods.

[0013] Preferably, a unwind reel and a guide roller are rotatably installed on one side of the processing table. One end of the side plate is fixedly connected with a connecting plate. A take-up reel is rotatably installed on the side edge of the end of the connecting plate away from the side plate. And a motor B for driving the take-up reel to rotate is detachably installed on one side of the connecting plate. One end of the carrier tape body is wound in the take-up reel, and the other end of the carrier tape body abuts against the outer edge surface of the guide roller and is wound in the unwind reel.

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

[0015] 1. By designing the positioning component A and the positioning component B, during the feeding process of the carrier tape body, the movement of the carrier tape body will drive the driven wheel to rotate, so that the positioning bump B is movably inserted into the positioning hole. Through the cooperation of the positioning bump B and the positioning hole, passive positioning of the carrier tape body during the feeding process is realized. The driving wheel can be driven to rotate through the motor A and the belt transmission mechanism, so that the positioning bump A is movably inserted into the positioning hole. Through the cooperation of the positioning bump A and the positioning hole, active positioning of the carrier tape body during the feeding process is realized. Thus, accurate positioning of the carrier tape body during the feeding process is achieved by combining active and passive positioning methods, which is beneficial to ensuring the stability of the placement of LED lamp beads, and solves the problem that when the existing feeding device conveys the carrier tape, it is not convenient to position the carrier tape, affecting the stability of the placement of LED lamp beads.

[0016] 2. The present utility model also designs the edge positions of the ends of the positioning bump A and the positioning bump B as rounded corner structures. When the positioning bump A and the positioning bump B are movably inserted into the positioning hole, the rounded corner structure is beneficial for them to be smoothly inserted into the positioning hole, avoiding the situation of edge jamming. And during the rotation of the driving wheel, the positioning wheel rotates synchronously and rolls against the bottom of the carrier tape body, which is beneficial to further improving the stability of the feeding process of the carrier tape body.

[0017] 3. The present utility model also designs a photoelectric distance measuring sensor. The distance moved by the carrier tape body during a single feeding process is detected by the photoelectric distance measuring sensor, so as to ensure the accurate distance of a single feeding of the carrier tape body and ensure that the LED lamp beads can be accurately placed in the carrier tape body.
