Description

Technical Field

[0001] This utility model relates to the field of storage technology for panel tape, and in particular to a tape hopper mechanism. Background Technology

[0002] In the production process of products such as LCD monitors and LCD panels, the LED strips along the edges of the light guide plate need to be coated with thermally conductive tape before assembly. This protects the LED strips, improves their heat dissipation capacity, and extends their lifespan. Applying a protective film before attaching the tape helps protect the adhesive surface of the tape and prevents dust and impurities from contaminating it. During application, the protective film must be removed first, and then the tape is attached to the LED strip.

[0003] In existing technologies, such as Figure 1 As shown, adhesive tape is typically in strip form. In automated production, the amount of adhesive tape used is large and the production pace is fast. Feeding each tape individually would affect production efficiency. Therefore, multiple tapes are usually neatly stacked together and picked up one by one by a transfer device such as a robotic arm, then transferred to the assembly station for film removal and attachment. During this process, if the tapes are not stacked neatly, the picking position may be inaccurate, affecting the repositioning of the tapes or the assembly accuracy in subsequent processes. In addition, because the tapes are soft and thin, if the picking speed is slightly increased when picking up the top tape, the negative pressure will pull out one or more tapes at the same time, causing the tapes to scatter disorderly and affecting the production process. Therefore, how to place the tapes in an orderly manner while avoiding picking up multiple tapes at the same time is a problem that those skilled in the art need to consider. Utility Model Content

[0004] The purpose of this invention is to provide a tape hopper mechanism to solve the problem of simultaneously gripping multiple tapes in the prior art.

[0005] The technical solution of this utility model is: a tape hopper mechanism, including a carrier plate for carrying tape and a positioning component that penetrates the carrier plate. The positioning component includes a first positioning rod and a second positioning rod disposed on both sides in a first direction, which are respectively disposed through the carrier plate where a first clearance window and a second clearance window are provided. A first brush and a second brush are respectively provided on the side of the first positioning rod and the second positioning rod that are close to each other, and the first brush and the second brush are positioned above the carrier plate; the tape is positioned between the first positioning rod and the second positioning rod, and when the tape is moved vertically upward, its two sides slide and rub against the first brush and the second brush respectively.

[0006] Preferably, the first positioning rod and the second positioning rod are respectively provided with a first groove and a second groove on their sides that are close to each other, the first brush and the second brush are respectively disposed in the first groove and the second groove, and the bristles of the first brush protrude from the first positioning rod, and the bristles of the second brush protrude from the second positioning rod.

[0007] Preferably, the lower end of the carrier plate is provided with a base plate, and the base plate is provided with a plurality of guide rods, the upper ends of the guide rods penetrating the carrier plate and connected to the carrier plate through guide sleeves.

[0008] Preferably, a driving device is provided on the base plate, and the driving device is connected to a first lead screw. The first lead screw is threadedly connected to the base plate, and its upper end is rotatably connected to the bottom of the carrier plate. The driving device drives the first lead screw to rotate, thereby driving the carrier plate to move vertically along the guide rod.

[0009] Preferably, the bottom end of the first positioning rod is fixedly mounted on the base plate.

[0010] Preferably, the bottom end of the second positioning rod is connected to the base plate via a slide rail with the sliding direction in the second direction; The bottom of the second positioning rod is threadedly connected to a second lead screw with the length direction in the second direction. The two ends of the second lead screw are connected to the base plate through the first base, and the end of the second lead screw is provided with a first handle. By rotating the first handle, the second lead screw rotates on the first base, thereby driving the second positioning rod to slide on the slide rail to move closer to or further away from the first positioning rod, thus achieving the positioning of the tape in the second direction.

[0011] Preferably, a third positioning rod is provided on the base plate, and the upper end of the third positioning rod penetrates through the carrier plate.

[0012] Preferably, a fourth positioning rod is provided on the base plate, and the fourth positioning rod and the third positioning rod are respectively provided at both ends of the carrier plate in the first direction; the carrier plate is provided with an elongated hole in the first direction, and the upper end of the fourth positioning rod passes through the elongated hole; The lower end of the fourth positioning rod is connected to a third lead screw with its length direction in the first direction. The third lead screw is connected to the second base and the base plate, and the end of the third lead screw is connected to a second handle. By rotating the second handle, the third lead screw rotates on the second base, thereby driving the fourth positioning rod to move in the first direction to move closer to or further away from the third positioning rod, thus achieving the positioning of the tape in the first direction.

[0013] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, by setting the first brush and the second brush, when the tape is grabbed and transferred, and multiple tapes are lifted at the same time, the excess tape can be wiped off by sliding the two sides of the tape with the first brush and the second brush respectively, thus avoiding the excess tape being carried out at the same time. By setting the drive device, each time a piece of tape is taken out, the carrier plate is driven to rise by the thickness of one piece of tape, so that the topmost piece of tape always maintains a small gap with the bottom of the brush. In this way, when the excess tape is brushed off during transfer, the falling stroke is reduced, and scattered falling tape is avoided, which would affect the accuracy of the placement position.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1-2 As shown, this utility model is applied to the temporary storage of adhesive tape 5 in the production of LCD panels. Multiple pieces of adhesive tape 5 are stacked on a carrier plate and positioned at the positioning component. The suction cup of the transfer device (not shown in the figure) picks up the topmost piece of adhesive tape 5 and moves it upward; when the adhesive tape 5 passes the first brush and the second brush, its two sides slide against the first brush and the second brush respectively to prevent multiple pieces of adhesive tape 5 from being carried out at the same time. After each piece of adhesive tape 5 is removed, the driving device drives the carrier plate to move upward by the thickness of one piece of adhesive tape 5, so that the adhesive tape 5 at the top of the nozzle is always on the same horizontal plane. Specifically: For ease of explanation, such as Figure 1As shown, the length direction of the tape 5 when it is placed is the first direction S1, and the direction perpendicular to the first direction S1 on the horizontal plane is the second direction S2.

[0017] A tape hopper mechanism includes a carrier plate 1 for carrying tape 5 and a positioning component 2 penetrating the carrier plate 1. The positioning component 2 includes a first positioning rod 21 and a second positioning rod 22 disposed on both sides in a first direction S1, respectively penetrating the carrier plate 1 at a first clearance window 11 and a second clearance window 12.

[0018] A first brush 211 and a second brush 221 are respectively provided on the side of the first positioning rod 21 and the second positioning rod 22 that are close to each other, and the first brush 211 and the second brush 221 are positioned above the carrier plate 1. In this embodiment, a first groove 212 and a second groove 222 are respectively provided on the side of the first positioning rod 21 and the second positioning rod 22 that are close to each other, and the first brush 211 and the second brush 221 are respectively disposed in the first groove 212 and the second groove 222, with the bristles of the first brush 211 protruding from the first positioning rod 21 and the bristles of the second brush 221 protruding from the second positioning rod 22. In this embodiment, the two ends of the tape 5 abut against the first positioning rod 21 and the second positioning rod 22 respectively in the second direction S2 to achieve positioning in the second direction S2. Therefore, the height of the first brush 211 and the second brush 221 protruding from the first positioning rod 21 and the second positioning rod 22 cannot be too large, otherwise it will affect the output of the tape 5.

[0019] A base plate 3 is provided at the lower end of the carrier plate 1. Multiple guide rods 31 are provided on the base plate 3. The upper ends of the guide rods 31 pass through the carrier plate 1 and are connected to the carrier plate 1 through guide sleeves 13. A driving device 4 is provided on the base plate 3. The driving device 4 is connected to a first lead screw 41. The first lead screw 41 is threadedly connected to the base plate 3, and its upper end is rotatably connected to the bottom of the carrier plate 1. The driving device 4 drives the first lead screw 41 to rotate, thereby driving the carrier plate 1 to move vertically along the guide rods 31.

[0020] In this embodiment, the bottom end of the first positioning rod 21 is fixedly mounted on the base plate 3. The bottom end of the second positioning rod 22 is connected to the base plate 3 via a slide rail 223 with a sliding direction of the second direction S2. The bottom of the second positioning rod 22 is threadedly connected to a second lead screw 224 with a length direction of the second direction S2. Both ends of the second lead screw 224 are connected to the base plate 3 via a first base 226, and a first handle 225 is provided at the end of the second lead screw 224. By rotating the first handle 225, the second lead screw 224 rotates on the first base 226, thereby driving the second positioning rod 22 to slide on the slide rail 223 to move closer to or away from the first positioning rod 21, thereby achieving the positioning of the tape 5 in the second direction S2.

[0021] The positioning assembly 2 also includes a third positioning rod 23 and a fourth positioning rod 24 disposed on the base plate 3. The upper end of the third positioning rod 23 penetrates through the carrier plate 1. The fourth positioning rod 24 and the third positioning rod 23 are respectively disposed at both ends of the carrier plate 1 in the first direction S1; the carrier plate 1 is provided with an elongated hole 14 with the length direction in the first direction S1, and the upper end of the fourth positioning rod 24 penetrates through the elongated hole 14.

[0022] The lower end of the fourth positioning rod 24 is connected to a third lead screw 241 with its length direction in the first direction S1. The third lead screw 241 is connected to the base plate 3 through the second base 242, and the end of the third lead screw 241 is connected to a second handle 243. By rotating the second handle 243, the third lead screw 241 rotates on the second base 242, thereby driving the fourth positioning rod 24 to move along the first direction S1, so as to move closer to or away from the third positioning rod 23, thereby achieving the positioning of the tape 5 in the first direction S1.

[0023] In this embodiment, the tape 5 is placed on the carrier plate 1, with the uppermost piece of tape 5 slightly lower than the lower ends of the first brush 211 and the second brush 221. By rotating the first handle 225, the second positioning rod 22 is driven to move along the second direction S2 towards the first positioning rod 21, contacting the tape 5 against the first positioning rod 21, thus completing the alignment and positioning of the tape 5 in the second direction S2. By rotating the second handle 243, the fourth positioning rod 24 is driven to move along the first direction S1 towards the third positioning rod 23, contacting the tape 5 against the third positioning rod 23, thus completing the alignment and positioning of the tape 5 in the first direction S1. Afterwards, the tape 5 is picked up by the suction cup on the transfer device and moved upwards. During the process of passing the first brush 211 and the second brush 221, if excess tape 5 adheres to the bottom of the tape 5, it can be removed by brushing with the first brush 211 and the second brush 221, causing the excess tape 5 to fall back onto the carrier plate 1, ensuring that one piece of tape 5 is removed each time. After each removal of tape 5, the drive device 4 drives the carrier plate 1 to move upward by the thickness of tape 5, so as to ensure that the uppermost tape 5 is always on the same horizontal plane, thereby increasing the stability of the transfer device in absorbing tape 5, and avoiding the situation where the gap between tape 5 and the first brush 211 or the second brush 221 is too large, causing excess tape 5 to fall and scatter.
