Description

Technical Field

[0001] This disclosure relates to the field of adhesive technology, and more particularly to an adhesive feeding device. Background Technology

[0002] In the normal production process of PMOLED (passive matrix organic electroluminescent diode), AMOLED (active matrix organic light-emitting diode), and TFT (thin-film transistor) products, it is usually necessary to add adhesive to the back of the product to increase its adhesion in order to facilitate customer assembly.

[0003] However, as Figure 1 As shown, the existing feeding mechanism for light-blocking / easy-tear tape uses an integrated feeding and label-dispensing structure. This leads to the following problem during use: when the adhesive backing needs to be adsorbed, the current method relies solely on the suction force of the nozzle to adsorb and peel off the adhesive, resulting in poor adhesive adsorption and severely impacting production efficiency. Currently, no effective solution has been proposed to address these issues. Summary of the Invention

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 2-5 As shown, this application relates to an adhesive feeding device. The adhesive feeding device includes: a bracket 10; the bracket 10 refers to a support frame, which can achieve good fixing and support effects; at the same time, it can also enable the assembly of various components, thereby achieving multiple functions.

[0032] The adhesive adsorption component 20 is disposed on one side of the support 10; it can achieve a good adhesive adsorption effect, thereby achieving the effect of separating the adhesive from the material strip; at the same time, assembling the adhesive adsorption component 20 on one side of the support 10 can improve the space utilization rate.

[0033] The telescopic component 30 is disposed adjacent to the adhesive adsorption component 20 on one side of the bracket 10 and located below the adhesive adsorption component 20. By providing the telescopic component 30, the material belt can be driven to move and extend in a horizontal direction, thereby achieving a good material belt driving effect.

[0034] Sensor 40 is connected to the top of the bracket 10; it enables real-time monitoring of the adhesive backing position, thereby ensuring the precise operation of other components. Sensor 40 includes, but is not limited to, an infrared sensor or a sensing fiber optic cable.

[0035] In this configuration, when the sensor 40 detects the adhesive backing at a preset position, the adhesive adsorption component 20 moves downward until it adsorbs the adhesive. The telescopic component 30 then moves the conveyor belt from a first initial position to a second end position to separate the conveyor belt from the adhesive backing. Firstly, by adjusting the sensor 40 to a preset detection position, accurate detection of the adhesive backing is ensured. The detected adhesive position signal is fed back to other components, which can be achieved through communication control or electrical control. The adhesive adsorption component 20 moves downward according to the position signal fed back by the sensor 40 until it adsorbs the adhesive backing. Simultaneously, to further improve the adhesive desorption effect, the telescopic component 30 moves from the first initial position to the second end position to separate the conveyor belt from the adhesive backing. This further improves the separation effect and efficiency. The first initial position is when the telescopic component 30 is located directly below the adhesive adsorption component 20, which provides good support and facilitates the adsorption component to apply good pressure to the adhesive. After the adhesive adsorption component 20 has finished adsorbing, the second end position of the telescopic component 30 moves, i.e., moves in the opposite direction to the feeding direction as shown in the figure, thereby driving the material belt to move in the opposite direction, thus making it easier for the material belt to separate and desorb from the adhesive.

[0036] As can be seen from the above description, this application achieves the following technical effects:

[0037] In this embodiment, a telescopic component 30 is added. When the sensor 40 detects the adhesive backing at a preset position, the adhesive adsorption component 20 moves downward until the adhesive backing is adsorbed. The telescopic component 30 drives the tape from the first initial position to the second end position, so that the tape and adhesive backing are separated. This achieves the purpose of moving the tape back and forth, thereby improving the adhesive backing removal efficiency. This solves the problem of the existing feeding mechanism used for light-blocking / easy-tear tapes, which uses an integrated structure for feeding and label removal. As a result, when the adhesive backing needs to be adsorbed, the current method relies solely on the suction force of the nozzle to adsorb and peel off the adhesive, resulting in poor adhesive adsorption and seriously affecting production efficiency.

[0038] like Figure 7As shown, the adhesive adsorption assembly 20 includes: a fixing plate 201 connected to the bracket 10; a first driving component 202 is vertically arranged on one side of the fixing plate 201; a first connecting plate 203 is arranged at the output end of the first driving component 202; a second driving component 204 is vertically arranged on the outer side of the first connecting plate 203; and an adsorption head 205 located directly above the adhesive is arranged at the output end of the second driving component 204. It can be understood that by using two driving components to drive the adsorption head 205 to move in a specific direction, not only can the stroke problem be avoided, but the material sensing problem can also be solved. If a cylinder is used, the sensor 40 will shine on the cylinder, causing false sensing. Therefore, this device avoids interference. The first driving component 202 and the second driving component 204 include, but are not limited to, a cylinder.

[0039] It should be understood that setting a corresponding limit sensor 40 to avoid overtravel is well known to those skilled in the art and is not limited in this application.

[0040] like Figure 8 As shown, the telescopic assembly 30 includes: a third driving component 301 connected to one side of the bracket 10; the output end of the third driving component 301 is connected to a first slider assembly 302 arranged along the feed direction of the material strip; a second connecting plate 303 is provided on the first slider assembly 302; a telescopic platform 304 is vertically arranged on the second connecting plate 303 away from the first slider assembly 302; a first limiting block 305 is arranged opposite to the top of the telescopic platform 304 along the feed direction of the material strip; an extension 306 is provided on the second connecting plate 303; a first roller 307 is vertically arranged on the extension 306 near the telescopic platform 304; the first roller 307 is located at the lower left of the telescopic platform 304. It can be understood that the third driving component 301 drives the first slider assembly 302 to move directionally along the feed direction, thereby causing the telescopic platform 304 to move back and forth along the feed direction, and thus causing the material strip on it to move synchronously. The third driving component 301 includes, but is not limited to, a cylinder. The first slider assembly 302 can be in the form of a slider and a rail.

[0041] Furthermore, an extension plate 50 is vertically arranged at the top of the bracket 10 away from the adhesive adsorption assembly 20. A driven wheel 60 is arranged on the side of the extension plate 50 near the telescopic assembly 30. A second roller 70 connected to the bracket 10 is arranged below the driven wheel 60. A driving wheel 80 connected to the bracket 10 is arranged below the second roller 70.

[0042] The material strip sequentially passes through the driven roller 60, the second roller 70, the telescopic component 30, the first roller 307, the third roller 90, and the two pressing rollers 100 before reaching the driving roller 80. It is understood that by providing the driving roller 80, the driven roller 60, and multiple rollers, the material strip can move along a preset trajectory, thereby ensuring that the adhesive on the material strip is in a detectable and absorbable state.

[0043] like Figure 6 As shown, a fourth driving component 110 is provided on the support 10 near the telescopic component 30. The output end of the fourth driving component 110 is located on the back side of the support 10. The output end of the fourth driving component 110 is connected to one end of the first synchronous transmission component 120, and the other end of the synchronous transmission component is connected to a pressure roller shaft 100. A second synchronous transmission component 130 is provided between the pressure roller shaft 100 and the drive wheel 80, and the second synchronous transmission component 130 is located near the first synchronous transmission component 120. It can be understood that by providing driving force through the fourth driving component 110, the driving force drives the pressure roller shaft 100 to move through the first synchronous transmission component 120, which can achieve a good power transmission effect, thereby achieving the effect of directional movement of the material belt. At the same time, by providing the second synchronous transmission component 130 between the pressure roller shaft 100 and the drive wheel 80, the effect of driving the drive wheel 80 to move can be achieved, thereby ensuring that the rotation of the drive wheel 80 drives the winding of the material belt. By using the pressure roller shaft 100 as an intermediate medium for power transmission, a good synchronous motion effect can be achieved. Among them, the third drive component 301 includes, but is not limited to, a servo motor.

[0044] Furthermore, the first synchronous transmission assembly 120 includes a first synchronous pulley 1201 connected to the output end of the fourth drive component 110, and the first synchronous pulley 1201 is connected to a second synchronous pulley 1203 disposed at one end of the pressure roller shaft 100 via a toothed belt 1202. It is understood that by using a toothed belt 1202 as the synchronous transmission belt, effective power transmission efficiency can be ensured.

[0045] Furthermore, the second synchronous transmission assembly 130 includes: a first pulley 1301 connected to one end of the pressure roller shaft 100; the first pulley 1301 is connected to a second pulley 1303 disposed at one end of the drive wheel 80 via a toothless belt 1302; and an idler pulley 1304 connected to the bracket 10 is disposed above the second pulley 1303. It is understood that, to solve the problem of the drive wheel 80 overloading and burning out the motor, using a toothless belt 1302 as the synchronous transmission belt between the pulleys can prevent the drive wheel 80 from overloading and burning out the motor. The toothless belt 1302 can be a round belt.

[0046] like Figure 9 As shown, a material belt smoothing component 140 is provided on the support 10 near the telescopic component 30. The material belt smoothing component 140 is located between the second roller 70 and the telescopic component 30. The smoothing device includes: a third connecting plate 1401 connected to the support 10. A fifth driving component 1402 with its output end facing the material belt is provided on the third connecting plate 1401. A smoothing head 1403 is provided at the output end of the fifth driving component 1402. The smoothing head 1403 is located above the material belt. A support platform 1404 horizontally connected to the support 10 is provided at the bottom of the material belt. The support platform 1404 cooperates with the smoothing head 1403 to smooth the material belt. A second limiting block 1405 is provided on the top of the support platform 1404 opposite to the material belt feeding direction. Understandably, to address the issue of the material strip warping and lack of smoothing, a smoothing device is installed on the material strip feed path, prior to the telescopic assembly 30. This ensures a smooth surface and guarantees the material strip remains flat, thus providing assurance for subsequent processing. The fifth drive component 1402 includes, but is not limited to, a cylinder.

[0047] Furthermore, a guide component is provided on the top of the support platform 1404, located at the front end of the material strip smoothing component 140; this enables good pre-positioning of the material strip, thereby preventing the material strip from deviating. The guide component can be a hollow guide plate.

[0048] Furthermore, a position adjustment component 150 is horizontally arranged at the bottom of the support 10. The position adjustment component 150 includes: a mounting plate 501 parallel to the bottom of the support 10; two second slider components 502 are arranged opposite each other on the mounting plate 501, and the two second slider components are arranged perpendicular to the feed direction of the material belt; limit adjustment components 503 are respectively arranged on both sides of the mounting plate 501 along the feed direction of the material belt, which abut against the second slider components 502; and the mounting plate 501 is located away from the limit adjustment components 503. A drive adjustment assembly 504 is provided on the side. The drive adjustment assembly 504 includes: a lead screw mounting base 5041 connected to one side of the mounting base and located between the two second slider assemblies 502; a trapezoidal lead screw 5042 is provided on the lead screw mounting base 5041; a nut 5043 connected to the bottom of the bracket 10 is provided on the trapezoidal lead screw 5042; and a rotating wheel 5044 is provided at one end of the trapezoidal lead screw 5042 near the lead screw mounting base 5041, with the rotating wheel 5044 located outside the lead screw mounting base 5041. It can be understood that, to solve the problem of inability to adjust the position in the Y-axis direction, the position adjustment assembly 150 is provided to achieve the position adjustment effect in the Y-axis direction, thereby facilitating assembly and, consequently, product alignment adjustment during material change or shape change processes. The second slider assembly 502 can be in the form of a slider and a slide rail.

[0049] Furthermore, a third slider assembly 160 is provided on the top of the bracket 10 near the adhesive adsorption component 20 and along the feed direction of the conveyor belt. A distance adjustment component 170 is provided on one side of the third slider assembly 160, and an extension rod 180 is provided at the output end of the third slider assembly 160. The sensor 40 for detecting the adhesive on the conveyor belt is provided on the extension rod 180. By providing the third slider assembly 160 on the top of the bracket 10, a good directional sliding effect can be achieved, thereby achieving the effect of moving the sensor 40. At the same time, by providing the distance adjustment component 170 on one side of the third slider assembly 160, a precise sensor 40 position adjustment effect can be achieved, thereby flexibly adapting to usage requirements. The third slider assembly 160 is a combination of a slider and a slide rail.

[0050] Specifically, the distance adjustment component 170 includes: a fixed block, on which a micrometer head is provided that abuts against one side of the slider, and one side of the slider is connected to the fixed block through a return spring; it can achieve good slider positioning and adjustment effect.

[0051] The working principle of this invention is as follows:

[0052] First, synchronous driving force is provided by the first synchronous transmission assembly 120 and the second synchronous transmission assembly 130, which drives the material belt from the driven wheel 60, through the material belt smoothing assembly 140, the telescopic assembly 30 and several rollers, and then wraps around the driving wheel 80.

[0053] Secondly, when the drive wheel 80 pulls the material belt forward, when the sensor 40 senses the adhesive on the material belt, the servo motor stops working, the adsorption head 205 of the adhesive adsorption component 20 descends, and at the same time the telescopic platform of the telescopic component 30 retracts, driving the material belt backward to facilitate the adsorption head 205 to adsorb the adhesive.

[0054] Next, after the adhesive is absorbed, the smoothing device descends to locate the length of the existing material strip, while the telescopic platform moves forward to complete one cycle.

[0055] Finally, the position adjustment component 150, i.e. the Y-axis adjustment device, is designed to facilitate product alignment during material or shape changes.

[0056] The present invention also has the following beneficial effects:

[0057] 1. Belt smoothing component: Used to smooth the belt and prevent warping caused by fluctuations during the belt's movement.

[0058] 2. Telescopic component: The adhesive retracts during the adsorption process, making it easier for the adhesive to peel off from the material belt, and allowing the adsorption head to adsorb the adhesive more smoothly.

[0059] 3. Position adjustment component, i.e. Y-axis adjustment device: including knob screw, slider and quick fastener, which can meet the movement of Y-axis during machine adjustment;

[0060] 4. The form of cooperation between the first synchronous transmission component and the second synchronous transmission component, namely the overload protection device for the drive wheel (overload protection device for the motor): a toothed belt is used to pull the intermediate wheel, and a toothless belt is used between the intermediate wheel and the feeding wheel. The rotation is driven by static friction. When the equipment is overloaded, the toothless belt slips, avoiding the gears from meshing and causing the motor to burn out.

[0061] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
