Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mounting, in particular to the field of electronic component mounting, and specifically relates to an apparatus and process for processing the tape head of a new tape reel. BACKGROUND

[0002] Tape is a strip-shaped product used in the field of electronic mounting, with a specific thickness, and equidistantly distributed cavities (cavities) for holding electronic components and positioning holes for indexing positioning in the length direction. The tape stored and transported after production is stored in the form of being wound on a reel. After winding a reel of tape, a tape head with a mark is provided at the end of the tape. The tape head is covered and adhered to the outer surface of the reel by a cover film and a tape head lead. The tape head lead can be pulled out to bring the tape for mounting. Before using the tape, the tape head and the lead need to be removed to expose the tape for subsequent work.

[0003] Currently, the devices for mounting electronic components using tape mostly use manual processing methods. The cover film or tape head lead outside the reel of tape is found and cut off, and then the reel is placed in the corresponding position of the mounting device. The end of the tape is pulled out and placed in the specified position, and then the mounting device is started to mount the electronic components. Due to manual pulling and placing, accurate positioning of the tape is often not achieved, manual operation stability is poor, processing efficiency is low, and it is increasingly difficult to meet the mounting requirements.

[0004] There are devices in the prior art that cut the tape head pulled into position, but there is a lack of devices that pull the tape head with a cover film or lead into position. For new reels, there is still no fully automated processing solution. SUMMARY

[0005] To solve the problems of the prior art, the present application provides a tape head finding device and a working method thereof, which accurately positions and pulls out the tape head on a new reel.

[0006] The technical problem to be solved by the present application is solved by the following technical scheme:

[0007] A tape head finding device is provided on a material receiving machine, comprising a rack, a reel holder and a scraper module provided on the rack, the reel holder comprising a rotating shaft, the center of the reel being sleeved on the rotating shaft, the scraper module being provided on one side of the reel holder, facing the tape and track on the reel of the reel holder, the scraper module comprising a scraper holder and a scraper, the scraper being provided at the front end of the scraper holder, the plane of the scraper being tangent to the tape on the reel, the scraper being flexibly attached to the surface of the tape on the reel, and the cutting edge of the scraper facing the junction of the scraper and the tape on the reel, facing the direction of the tape delivered.

[0008] In the present application, the scraper module is arranged on the rack through a scraper telescopic module, and the scraper telescopic module comprises a flexible pressing structure.

[0009] In the present application, the scraper frame is provided with an inductor, which is located below the scraper, and the identification end of the inductor faces the carrier tape on the tray, and the inductor identifies the mark, such as a color mark, at the head of the carrier tape.

[0010] Further, the rotating shaft of the tray frame is driven by a stepping motor and can rotate forward and reverse by a certain angle freely.

[0011] Further, the outer side of the tray frame is provided with an auxiliary wheel, which is a friction wheel and is pushed by the auxiliary wheel pushing module and pressed onto the carrier tape of the tray track.

[0012] Further, the auxiliary wheel is driven to rotate by an auxiliary wheel motor, and the rotating direction is opposite to that of the tray.

[0013] In the present application, the flexible pressing structure of the scraper telescopic module comprises a spring, which pushes the scraper to press onto the carrier tape of the tray in a flexible manner.

[0014] In the present application, the blade of the scraper is flat or sawtooth-shaped.

[0015] The working method of the carrier tape head finding device based on the above structure comprises the following steps:

[0016] S1: placing a tray: placing a new tray on the tray frame, and the center of the tray is sleeved on the rotating shaft of the tray frame;

[0017] S2: pushing the scraper: the scraper telescopic module pushes the scraper module, so that the scraper module approaches the carrier tape of the tray, and the stepping motor of the tray frame drives the rotating shaft to rotate the tray forward;

[0018] S3: positioning the head: the auxiliary wheel pushing module pushes the auxiliary wheel, so that the auxiliary wheel is pressed onto the carrier tape of the tray track, the scraper telescopic module pushes the scraper module, so that the blade of the scraper is flexibly attached to the surface of the carrier tape on the tray, and then the tray frame is slightly retreated, then the stepping motor of the tray frame drives the rotating shaft to rotate the tray forward, the auxiliary wheel motor drives the auxiliary wheel to rotate in cooperation with the tray, and after the inductor of the scraper module identifies the mark at the head of the carrier tape on the tray, the stepping motor of the tray frame drives the rotating shaft to rotate the tray reverse by a certain angle, so that the head of the carrier tape retreats to the front of the blade of the scraper, and then the scraper module is flexibly attached to the carrier tape on the tray.

[0019] S4: cutting the step cover film: the scraper of the scraper module is inserted below the step at the head end of the carrier tape with the rotation of the tray, cuts the leading tape or cover film at the head end of the carrier tape, and lifts the carrier tape with the head.

[0020] S5: send out the carrier tape head: the tray rotates to send out the carrier tape head to the material head track, and the subsequent camera takes a picture to identify whether the material head has a material boundary.

[0021] Compared with the prior art, the present application has the following advantages:

[0022] The present application attaches the scraper to the surface of the carrier tape on the tray. Since the carrier tape and the material head have a certain thickness, the leading tape or the cover film covers the outside of the material head, so that the end of the carrier tape and the material head presents a certain step. The scraper blade points to the direction of the carrier tape sent by the tray, which can conveniently cut the leading tape or the cover film at the material head and lead the carrier tape and the material head out of the tray, facilitating subsequent application.

[0023] The present application drives the tray through the forward and reverse stepping motor, which can effectively control the tray to fully interact with the scraper, thereby improving the working effect of the scraper.

[0024] The present application sets an inductor at the scraper to identify and accurately position the position of the carrier tape and the material head on the tray, thereby improving the working efficiency of the scraper.

[0025] The present application statically presses the carrier tape on the tray through the auxiliary wheel, and rotates with it, so that the carrier tape does not retreat under stress during the working process of the scraper, thereby further improving the working effect and efficiency of the scraper.

[0026] The scraper module of the present application is statically pressed to the surface of the carrier tape on the tray under the action of the flexible top pressure structure, thereby avoiding damage that may be caused by the rigid pushing pressure of the scraper on the carrier tape of the tray.

[0027] The working method of the present application is automatically performed or started based on certain feedback conditions, and is unmanned and highly automated.

[0028] Therefore, the present application has novel concept, ingenious design, can accurately position and pull out the carrier tape and the material head on the new tray, has high processing efficiency, and is highly automated. BRIEF DESCRIPTION OF DRAWINGS
