Description

Technical Field

[0001] The invention relates to a carrier tape winding technology, and in particular to an automatic carrier tape winding machine. Background Art

[0002] After the carrier tape is produced, it needs to be covered with isolation paper and reeled into a reel to facilitate the subsequent loading of electronic components. The existing method is to simultaneously transport the carrier tape and isolation paper to the composite station for operation. However, in the process of changing the reel, the connection process of the carrier tape and isolation paper mainly relies on manual operation, which requires human intervention or frequent manual operation, and often requires a long period of downtime and adjustment, resulting in a longer response time in the overall production process, affecting production efficiency. In addition, during the cutting and reeling process of the carrier tape and isolation paper, there is no special tension control device, which makes it difficult to keep the tension of the isolation paper constant between different processes, increasing the risk of the isolation paper being pulled apart or damaged, thereby affecting the stability of the entire production process and product quality. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic carrier winder to solve the problem that when processing release paper in the prior art, there is a lack of an effective tension control mechanism, which leads to unstable tension of the release paper during transportation, increases the risk of the release paper being broken or damaged, and further affects the stability of the entire production process and product quality.

[0004] In order to achieve the above-mentioned object, the present invention provides the following technical solution: an automatic carrier tape winding machine, comprising a left-feed storage belt mechanism, a left-feed transmission ratchet mechanism, a belt threading mechanism and a winding mechanism for conveying the carrier tape and arranged in sequence, and also comprising:

[0005] A left-feed cutting mechanism, which is arranged between the left-feed transmission ratchet mechanism and the tape threading mechanism, and is used to cut off the carrier tape and the release paper;

[0007] A left-feed tape-applying mechanism, which is located above the left-feed cutting mechanism;

[0008] The release paper buffer mechanism is arranged between the release paper feeding mechanism and the left feed transmission ratchet mechanism, and is used to control the tension of the release paper during the conveying process, and to control the length of the release paper between the release paper feeding mechanism and the left feed transmission ratchet mechanism.

[0009] Furthermore, the isolation paper buffer mechanism includes a first bracket and a tension wheel, the tension wheel is rotatably mounted on a first wheel frame that can move freely along the length direction of the first bracket, and limit sensors are arranged on both travel ends of the first wheel frame on the first bracket, and the limit sensors are electrically connected to the isolation paper feeding mechanism.

[0010] Furthermore, the left feed transmission ratchet mechanism includes a combination wheel for conveying the carrier tape and the release paper, and the combination wheel is connected to a stepping motor for driving the combination wheel to rotate.

[0011] Furthermore, the combination wheel comprises a combination main wheel, a combination secondary wheel and a ratchet pressing swing wheel, and a needle-toothed ratchet matching with the limiting hole of the carrier belt is arranged on the circumference of the combination main wheel.

[0012] Furthermore, the left-feed cutting mechanism includes a guide seat and a pressure plate, and a cutting knife that can move along the width direction of the carrier tape is arranged on one side of the guide seat.

[0028] 100. Carrier tape. DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] For examples, see Figure 1 - Figure 8 , an automatic carrier tape winding machine, comprising a left-feed storage belt mechanism 2, a left-feed transmission ratchet mechanism 3, a belt threading mechanism 4 and a winding mechanism 5, which are used to convey a carrier tape 100 and are arranged in sequence, and also includes:

[0031] A left feed cutting mechanism 6, which is arranged between the left feed transmission ratchet mechanism 3 and the tape threading mechanism 4, and is used to cut off the carrier tape 100 and the release paper;

[0032] The release paper feeding mechanism 7 conveys the release paper to the left feeding cutting mechanism 6 and covers one side of the carrier tape 100;

[0033] A left-feed tape-applying mechanism 8, which is located above the left-feed cutting mechanism 6;

[0034] The release paper buffer mechanism 9 is arranged between the release paper feeding mechanism 7 and the left feed transmission ratchet mechanism 3, and is used to control the tension of the release paper during the conveying process, and to control the length of the release paper between the release paper feeding mechanism 7 and the left feed transmission ratchet mechanism 3.

[0035] It should be noted that the left-feed storage belt mechanism 2 is connected to the output end of the carrier belt 100 in the previous process, and the left-feed transmission ratchet mechanism 3 is used to composite the carrier belt 100 and the release paper, and transport it to the belt threading mechanism 4, which is then transported to the winding mechanism 5 for winding, which will not be described in detail here;

[0036] In one embodiment of the present invention, the release paper buffer mechanism 9 includes a first bracket 91 and a tension wheel 92, the tension wheel 92 is rotatably mounted on a first wheel frame 93 that can move freely along the length direction of the first bracket 91, and the first bracket 91 is provided with limit sensors 94 at both ends of the travel of the first wheel frame 93, and the limit sensors 94 are electrically connected to the release paper feeding mechanism 7;

[0037] like Figure 2 As shown, the first bracket 91 is composed of two support plates, the two support plates have a gap for accommodating a tension wheel 92, the width of the tension wheel 92 is greater than the width of the release paper, the tension wheel 92 is rotatably mounted on the first bracket 91, and the two support plates are provided with a slide groove for the first bracket 91 to slide, and the first bracket 91 is fixedly mounted on the frame 1. It should be understood that the release paper buffer mechanism 9 should be installed below the release paper feeding mechanism 7, and its height is lower than the height of the left feed transmission ratchet mechanism 3;

[0038] In one embodiment of the present invention, the top of the first bracket 91 is also rotatably connected to two conveying wheels 95, and the two conveying wheels 95 are located on both sides of the tension wheel 92. The tension wheel 92 makes the release paper U-shaped under its own weight, and the release control of the release paper feeding mechanism 7 is coordinated with the self-weight of the tension wheel 92 to achieve the adjustment of the release paper length between the release paper feeding mechanism 7 and the left feed transmission ratchet mechanism 3, and the release paper is tensioned under the self-weight of the tension wheel 92, so that the tension of the release paper is constant within a certain range;

[0039] Specifically, when the left-feed cutting mechanism 6 cuts the carrier tape 100 and the release paper, the left-feed adhesive tape mechanism 8 will also cooperate with the tape threading mechanism 4 to perform continuous reeling after the reel is replaced, and during this process, the release paper buffer mechanism 9 can buffer a certain length of release paper by moving the tension wheel 92, so that the release paper unloading mechanism 7 does not need to be stopped;

[0040] Generally, the time for the left-feed adhesive tape mechanism 8 to cooperate with the tape threading mechanism 4 to change the reel does not exceed the time for the first wheel frame 93 to move to the limit sensor 94 located below, so that the release paper feeding mechanism 7 always keeps running without stopping. It should be noted that when the left-feed cutting mechanism 6 is cutting, the speed of the release paper feeding mechanism 7 to convey the release paper is reduced to match the time for the left-feed adhesive tape mechanism 8 to cooperate with the tape threading mechanism 4 to change the reel. When the reel change is completed and the reeling continues, the speed of the release paper feeding mechanism 7 to convey the release paper is restored to the original working state;

[0041] When other factors cause the disk change completion time to time out, the release paper unloading mechanism 7 will be triggered when the first wheel frame 93 connected to the tension wheel 92 moves to the limit sensor 94 located below, so that it stops conveying the release paper to prevent the excessive length of the release paper output from accumulating between the release paper unloading mechanism 7 and the left feed transmission ratchet mechanism 3. Similarly, when some factors cause the first wheel frame 93 to move to the limit sensor 94 located above, the release paper unloading mechanism 7 accelerates the conveying of the release paper.

[0042] In the above-mentioned different processes, the tension wheel 92 always keeps a relatively stable tension on the release paper under the action of its own gravity. Although the conveying speed is affected by the changes in the front and rear process mechanisms, the release paper can be stably conveyed at a relatively constant tension, thereby reducing the risk of the release paper being broken by a large tension, and improving the stability of the left-feed cutting mechanism 6 before and after cutting the carrier tape 100 and the release paper, as well as the left-feed taping mechanism 8 cooperating with the tape threading mechanism 4 to change the reel and the continuous winding operation.

[0043] In one embodiment of the present invention, the left feed transmission ratchet mechanism 3 includes a combination wheel 31 for conveying the carrier tape 100 and the release paper, the combination wheel 31 is connected to a stepper motor 32 for driving it to rotate, and the stepper motor 32 is fixedly mounted on the frame 1;

[0044] In one embodiment of the present invention, the combination wheel 31 includes a combination main wheel 311, a combination secondary wheel 312 and a ratchet pressing swing wheel 313, and a needle-toothed ratchet matching with the limiting hole of the carrier tape 100 is arranged on the peripheral side of the combination main wheel 311;

[0045] like Figure 1 and Figure 4 As shown, the ratchet pressing material swing wheel 313 is arranged on one side of the combination wheel 31, and is pressed on the combination wheel 31 by providing pressure through the tension spring 314. When in use, first lift the ratchet pressing material swing wheel 313, clamp the carrier tape 100 and the isolation paper between the ratchet pressing material swing wheel 313 and the combination wheel 31, and limit the limiting hole of the carrier tape 100 with the needle-toothed ratchet wheel, and then release the ratchet pressing material swing wheel 313 and press it on the surface of the combination wheel 31. Two ratchet pressing material swing wheels 313 can be set, and the other one is used to provide a guiding effect for the isolation paper;

[0046] In one embodiment of the present invention, the stepper motor 32 and the combination wheel 31 are connected by an electromagnetic clutch 33, which is a prior art and will not be described in detail here. Furthermore, the encoder 34 is connected to the rotating shaft of the combination wheel 31 through a synchronous belt and a synchronous wheel transmission to calculate the conveying length of the carrier tape 100.

[0047] In one embodiment of the present invention, the left-feed cutting mechanism 6 includes a guide seat 61 and a pressure plate 62, and a cutting knife 63 capable of moving along the width direction of the carrier tape 100 is provided on one side of the guide seat 61;

[0048] In one embodiment of the present invention, one end of the guide seat 61 is docked with the combination wheel 31 and has an arc surface adapted to the combination wheel 31, which acts to make the plane where the channel for conveying the carrier tape 100 and the release paper at the top of the guide seat 61 is located tangent to the side of the combination wheel 31, thereby improving the stability of the docking. A pressing plate 62 is provided at the top of one end of the guide seat 61 close to the combination wheel 31, for forming a channel for conveying the carrier tape 100 and the release paper; Figure 6 As shown, the movement and cutting method of the cutting knife 63 are prior arts and will not be described in detail here.

[0049] In one embodiment of the present invention, the threading mechanism 4 includes a feed swing rod 41, a feed track 42 is provided on the feed swing rod 41, one end of the feed swing rod 41 is connected to a swing block 43, one end of the swing block 43 is rotatably connected to the output end of the cylinder, one end of the feed swing rod 41 is connected to the cutting mechanism, and the other end extends into the winding disk and is pressed and positioned with the surface of the winding core shaft of the winding disk;

[0050] In one embodiment of the present invention, a limiting column head 44 is also provided at the bottom of the feed rocker arm 41, and the limiting column head 44 is connected to a lifting cylinder for adjusting the height of the limiting column head 44 and providing support for the feed rocker arm 41, and the lifting cylinder is fixedly mounted on the frame 1.

[0051] In one embodiment of the present invention, the left-feed tape mechanism 8 includes a tape feeding assembly 81, a tape cutting assembly 82 and a tape adsorption assembly 83. The tape cutting assembly 82 is used to cut a certain length of tape and move at least part of the tape to the bottom of the tape adsorption assembly 83, and the adhesive surface of the tape faces away from the tape adsorption assembly 83. The tape adsorption assembly 83 can move toward the direction close to the left-feed cutting mechanism 6 and press the tape on the surface of the cut release paper. The tape adsorption assembly 83 includes a tape suction block 831.

[0052] In one embodiment of the present invention, it should be noted that the left-feed tape-sticking mechanism 8 is a method of the prior art. Specifically, during the reel changing process, after the left-feed cutting mechanism 6 completes cutting, the back side of the tape is adsorbed by the tape suction block 831, and the cylinder pushes the tape suction block 831 with the tape adsorbed on the bottom to move as a whole, so that the tape is attached to the tail end of the carrier tape 100, and then the tape suction block 831 is separated from the tape, and as the winding device is wound, the tape attachment at the tail end is completed; then the tape is continuously pulled out to a preset length, and the above process is repeated again, the difference being that at this time the tape suction block 831 will move to the head end of the cut carrier tape 100 and the isolation paper for attachment, and a cycle of taping operation is completed; initially, the head end of the tape needs to be manually pulled out and pulled to the bottom of the tape suction block 831.

[0053] In one embodiment of the present invention, the "left feed" mentioned above only represents the feeding direction of the carrier tape 100. According to actual production needs, the arrangement of the above structure may be changed according to the actual feeding direction and should not be understood as a limitation on its direction.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
