Description

Technical Field

[0001] This utility model relates to the field of tape application technology, and in particular to a tape storage 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 adhesive strips before assembly. This protects the LED strips, improves their heat dissipation capacity, and extends their lifespan. Before bonding with the LED strip, the tape is adhered to a protective film, which helps protect the adhesive surface of the tape and prevents contamination from dust and impurities. During application, the protective film must be removed first, and then the tape is applied to the LED strip. Furthermore, to optimize the production process, such as... Figure 6 As shown, multiple adhesive strips are typically attached to a single protective film. Multiple strips can be used in a single film removal operation. After removing the protective film, the adhesive strips need to be placed in a temporary storage area for subsequent positioning and assembly with the LED strips.

[0003] In existing technologies, adhesive strips are relatively lightweight and prone to static electricity. Therefore, when placing the adhesive strips in the feeding assembly, a vacuum breaking (reverse air blowing) is used to prevent the strips from sticking to the feeding assembly due to static electricity or negative pressure. However, this vacuum breaking method applies pressure to the adhesive strips. Therefore, even if the temporary storage mechanism uses an anti-adhesion material, it is impossible to completely prevent adhesion to the adhesive strips during this process. This can lead to the strips being unable to be removed, or significant displacement during removal due to adhesion, affecting the stability of the transfer and the accuracy of the assembly. Therefore, how to prevent the adhesive strips from sticking to the temporary storage mechanism and ensure the stability of the strips during removal are issues that those skilled in the art need to consider. Utility Model Content

[0004] The purpose of this invention is to provide a temporary tape storage mechanism to solve the problems of tape adhesion affecting transportation in the prior art.

[0005] The technical solution of this utility model is: a tape storage mechanism, comprising: A base plate is connected to the machine tool via a first guide rail, and a first driving device is connected to the base plate; A carrier plate is set above the base plate, and the carrier plate is provided with multiple through clearance grooves; The feeding assembly, when transferring the tape to the carrier plate, has a lower end face of the feeding assembly and the carrier plate at a distance greater than the thickness of one tape. The unloading assembly removes the adhesive strip from the carrier plate; While the feeding component places the tape onto the carrier plate, the first driving device drives the carrier plate to move through the base plate, forming a movement that is offset from the feeding component.

[0006] Preferably, the length direction of the clearance groove is not parallel to the moving direction of the first guide rail.

[0007] Preferably, a sensing plate is provided on the base plate, and a plurality of sensors connected to the sensing plate are provided on the machine base; The sensors are arranged in a straight line, and their arrangement direction is parallel to the movement direction of the first guide rail.

[0008] Preferably, a lifting assembly is connected to the base plate. The lifting assembly includes a lifting drive device and a lifting rod connected to the lifting drive device. The upper end of the lifting rod can pass upward through the clearance groove.

[0009] Preferably, the lifting drive device is connected to the base plate via a second drive device, wherein the second drive device drives horizontally and in the same direction as the length of the clearance groove.

[0010] Preferably, there are multiple lifting rods, and the arrangement direction of the multiple lifting rods is the same as the length direction of the tape.

[0011] Preferably, the feeding assembly includes a first suction plate, and the first suction plate is provided with a plurality of first negative pressure holes.

[0012] Preferably, the feeding assembly includes a second suction plate, and the second suction plate is provided with a second negative pressure hole group.

[0013] Preferably, a positioning plate is provided on the side of the carrier plate, the positioning plate protrudes upward from the carrier plate, and the side of the positioning plate closest to the carrier plate is the positioning surface; When the feeding component picks up the adhesive strip from the carrier plate, it first drives the adhesive strip to abut against the positioning surface for positioning.

[0014] Compared with the prior art, the advantages of this utility model are: (1) While the feeding component is placing the adhesive strip, the first driving device drives the carrier plate to move instantaneously, generating an instantaneous misalignment action with the feeding component, which effectively avoids the adhesive strip sticking to the carrier plate when it is placed. (2) When the tape is removed, the unloading component picks up the tape while the lifting drive device lifts the tape upward so that the tape is separated from the carrier plate surface, so that the tape can be removed stably. At the same time, after the tape is removed, the edge of the tape abuts against the positioning surface to adjust the position of the tape, so as to facilitate subsequent assembly.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-5 As shown, this utility model is a temporary storage mechanism 2 for adhesive tape, used for temporary storage of light strips after the protective film has been removed before assembly with the adhesive tape. At the feeding assembly 3, multiple adhesive strips are transferred to a carrier plate for temporary storage after the protective film is removed simultaneously; the lifting drive device lifts the adhesive strips one by one upwards, and the unloading assembly 4 removes the corresponding adhesive strip each time and transfers it to the next process. Specifically: A tape storage mechanism includes a machine base 1. A base plate 21 is connected to the machine base 1 via two parallel first guide rails 211. The base plate 21 is also connected to the machine base 1 via a first drive device 22. The first drive device 22 can be a combination of a lead screw and a motor, or a cylinder, direct drive motor, etc., and can drive the base plate 21 to reciprocate on the first guide rails 211. A sensing plate 212 is provided on the base plate 21. Multiple sensors 213 connected to the sensing plate 212 are provided on the machine base 1. The sensors 213 are arranged in a straight line, and their arrangement direction is parallel to the movement direction of the first guide rails 211. At least two sensors 213 are provided. When a sensor 213 senses the sensing plate 212, it indicates that the travel of the base plate 21 in a certain direction on the first guide rails 211 has reached a maximum set value, and the first drive device 22 can stop driving.

[0018] Carrier plates 23 are fixedly connected to both sides of the upper end of the base plate 21 via first brackets 214, and the carrier plates 23 are positioned directly above the base plate 21. A lifting assembly 24 is provided between the base plate 21 and the carrier plates 23. The lifting assembly 24 includes a second drive device 241 connected to the carrier plates 23 with a horizontal driving direction, a lifting drive device 242 connected to the second drive device 241 with a vertical driving direction, and a lifting rod 243 connected to the lifting drive device 242. The second drive device 241 and the lifting drive device 242 can be linear modules, cylinders, motors, or other devices that can achieve linear motion.

[0019] The carrier plate 23 has multiple through-hole relief grooves 231, which are elongated and arranged in parallel. The lifting rods 243 are vertically arranged, and their number corresponds to the number of relief grooves 231. Multiple lifting rods 243 are simultaneously connected to a lifting drive device 242, which allows them to move vertically under the drive of the lifting drive device 242, causing the upper ends of the lifting rods 243 to pass upwards through the relief grooves 231 and protrude from the upper surface of the carrier plate 23. It should be noted that the relief grooves 231 not only provide clearance for the lifting rods 243 but also reduce the contact area between the adhesive strip and the carrier plate 23, further reducing the risk of adhesion. Additionally, a positioning plate 232 is provided on the side of the carrier plate 23, protruding upwards from the carrier plate 23, with its side closest to the carrier plate 23 serving as the positioning surface 233.

[0020] Multiple adhesive strips are placed on the carrier plate 23, and the length direction of the adhesive strips is perpendicular to the length direction of the relief groove 231. Therefore, in this embodiment, the driving direction of the second driving device 241 is the same as the length direction of the relief groove 231. The second driving device 241 can drive the lifting rod 243 to move along the direction of the relief groove 231, stopping one by one under each adhesive strip, so as to lift all the adhesive strips.

[0021] The length direction of the relief groove 231 is not parallel to the movement direction of the first guide rail 211. In a preferred embodiment, the length direction of the relief groove 231 is perpendicular to the movement direction of the first guide rail 211.

[0022] In addition, the machine 1 is equipped with a feeding component 3 and a discharging component 4.

[0023] The feeding assembly 3 is equipped with a first suction plate 31, which has multiple first negative pressure hole groups 311. The number of first negative pressure hole groups 311 corresponds to the number of adhesive strips on each protective film. When the feeding assembly 3 picks up the adhesive strips, each first negative pressure hole group 311 corresponds to one adhesive strip, so that the corresponding adhesive strip completely covers the corresponding first negative pressure hole group 311. Driven by the feeding assembly 3, it first moves to the film-tearing mechanism (not shown in the figure) to tear off the protective film, and then places the adhesive strip on the carrier plate 23.

[0024] The feeding assembly 4 is equipped with a second suction plate 41, which has a second negative pressure hole group 411. The second negative pressure hole group 411 corresponds to an adhesive strip, and when the adhesive strip is picked up, it completely covers this group of second negative pressure holes 411. The width of the second suction plate 41 is slightly smaller than the width of the adhesive strip; that is, when the second suction plate 41 picks up the adhesive strip, both sides of the adhesive strip protrude from the sides of the second suction plate 41 in the width direction. When the feeding assembly 4 drives the adhesive strip to transfer, it first drives the adhesive strip to the positioning plate 232, so that the side of the adhesive strip abuts against the positioning surface 233 to adjust the position of the adhesive strip on the second suction plate 41; then it drives the adhesive strip to the assembly mechanism (not shown in the figure) to assemble with the light strip. Of course, before assembly, the light strip and adhesive strip also need to undergo visual positioning and other operations to further ensure the accuracy of the assembly. This process is irrelevant to the content of this utility model and will not be described here.

[0025] It should be noted that when the feeding assembly 3 places the adhesive strip, when the first suction plate 31 carries the adhesive strip to above the carrier plate 23, a gap is formed between its lower end face and the upper end face of the carrier plate 23, and this gap should be greater than the thickness of one adhesive strip. During placement, the negative pressure hole of the first suction plate 31 blows air in the opposite direction to form a vacuum, blowing the adhesive strip away from the first suction plate 31 and moving it towards the carrier plate 23; at the same time, the first driving device 22 drives the carrier plate 23 to move instantaneously along the direction of the first guide rail 211, forming a staggered movement with the first suction plate 31, so that dynamic friction is formed between the adhesive strip and the carrier plate 23 at the moment of contact, so as to avoid large adhesion between the adhesive strip and the carrier plate 23.

[0026] When the unloading assembly 4 removes the adhesive strip, the second drive device 241 drives the lifting rod 243 to move directly below the corresponding adhesive strip, and the lifting drive device 242 drives the lifting rod 243 to move upward to lift the adhesive strip upward until it is separated from the carrier plate 23; at the same time, the second suction plate 41 picks up the corresponding adhesive strip and transfers it to the positioning plate 232 for position adjustment, thus completing the material picking operation.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
