[0002] ACF (Anisotropic Conductive Film) is a key connection material and is widely used in fine connection scenarios such as chips and substrates, flexible circuit boards, etc. Its attachment quality directly affects the electrical performance, stability and reliability of electronic products. Taking the display panel field as an example, in the bonding technology of display panels, ACF glue needs to be used for attachment. In related technologies, ACF guide wheels are used in the ACF glue attachment process.

[0003] At present, the commonly used ACF guide wheel needs to be adjusted in size according to the size required for product processing. On the one hand, the accuracy of the above size adjustment is relatively poor, which will affect the quality of ACF glue attachment to a certain extent, and thus affect the yield of the final product; on the other hand, the removal and replacement of the ACF guide wheel will also cause wear on the guide wheel itself, further affecting the accuracy of ACF glue attachment.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0054] In the display panel processing flow, ACF attachment is usually a pre-step before connecting a chip (such as a driver chip) to the array substrate of the display panel. In the entire process, the array substrate of the prepared display panel needs to be connected (i.e. bonded) to the chip by ACF attachment.

[0055] ACF (Anisotropic Conductive Film) has good electrical and mechanical connection properties, and also has a certain buffering effect. In the display panel, the chip needs to send signals to the light-emitting elements located on the array substrate to control the working state of the light-emitting elements. After the chip is connected to the array substrate through the ACF glue, the above signal can be effectively transmitted to the array substrate through the ACF and realize the control of the light-emitting intensity and light-emitting color of the light-emitting elements to achieve high-quality image display. In addition, the ACF glue can also fully fill the tiny gap formed between the array substrate and the chip, so that the two fit tightly. Due to the characteristics of the ACF material and the requirements of the attachment process, when the dimensional accuracy of the ACF glue is insufficient, the conductive path between the chip and the array substrate may be incomplete, resulting in poor electrical connection. The display panel exhibits faults such as screen distortion, flickering, or even failure to display.

[0056] In order to improve the ACF lamination accuracy, in the related art, it is necessary to strictly control the accuracy of the ACF guide wheel 2, and to meet the ACF lamination requirements by adjusting the width of the corresponding fixing groove on the guide wheel 2. However, the above adjustment method is relatively complicated, and frequent disassembly and assembly will also cause wear to the guide wheel 2, and further affect the accuracy of the ACF guide wheel 2.

[0057] Based on this, the embodiment of the present application provides a new conveying guide module 10, which can adjust the accuracy of the guide wheel 2 without disassembly, and the guide wheel 2 is basically wear-free.

[0058] For details, please refer to Figure 1 An embodiment of the present application provides a conveying guide module 10, which includes a module body 1 and guide wheels 2, wherein the number of guide wheels 2 is at least two and they are installed on the module body 1 along the circumference of the module body 1; a guide member 21 is provided on the side of any guide wheel 2 facing away from the middle of the module body 1, and the guide member 21 is used to guide or convey the material to be attached.

[0059] In the conveying guide module 10 provided in the present application, by providing a module body 1 equipped with a plurality of guide wheels 2, the problem of repeated disassembly of the guide wheels 2 can be overcome. The conveying guide module 10 in this embodiment can fix a plurality of guide wheels 2 that meet the required size for processing on the module body 1. When it is necessary to adjust the guide wheels 2 of different sizes according to the product processing requirements, it is only necessary to adjust the position of the module body 1 so that the guide wheels 2 that meet the required size are moved to the incoming material position of the material to be attached. Since there is no need to load and unload the guide wheels 2 and adjust the precision, the problem of insufficient attachment precision of the guide wheels 2 can be effectively improved, and the processing yield of the display panel can be improved.

[0060] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the conveying guide module 10 provided in an embodiment of the present application. Figure 2 A top view of the conveying guide module 10 provided in an embodiment of the present application.

[0061] In some embodiments, the module body 1 is a columnar structure as a whole, and the number of guide wheels 2 is six and they are respectively arranged on the outer side of the module body 1 in the circumferential direction.

[0062] by Figure 1 Taking the structure shown as an example, six guide wheels 2 are fixedly mounted on the module body 1, wherein the sizes of the guide members 21 on different guide wheels 2 are 0.6mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm, and 2.5mm, respectively. The size selection of each of the guide members 21 is determined by the ACF size commonly used in actual processing. Those skilled in the art can make adaptive adjustments to the above range according to the needs of actual processing. For example, 2.5mm can be adjusted to 0.4mm, or other values.

[0063] The guide member 21 may be a guide plane that is recessed toward the middle relative to the outer side wall of the guide wheel 2. Specifically, the guide plane is a rectangular plane.

[0064] Of course, the guide member 21 may also be a groove structure with a significant groove.

[0065] In any one of the conveying guide modules 10, the sizes of the guide members 21 on at least two guide wheels 2 are different. Of course, in special cases, the sizes of the guide members 21 on at least two guide wheels 2 can also be adjusted to be the same as required.

[0066] The above dimensions refer to the length of the guide member 21 in the axial direction of the guide wheel 2 .

[0067] In other similar embodiments, the number of guide wheels 2 installed on the module body 1 can also be adaptively adjusted according to actual processing needs. Generally speaking, the number of guide wheels 2 is at least two, and can be at most more than ten. For example, the number of guide wheels 2 can be adjusted to three, four, five, or even seven, eight, nine, etc. It can be understood that as the number of guide wheels 2 increases, the size of the module body 1 gradually increases.

[0068] In addition, all guide wheels 2 are arranged in sequence at intervals, and the distance between any two guide wheels 2 should be sufficient to ensure that the two adjacent guide wheels 2 do not affect each other.

[0069] In actual use, one axial end of the module body 1 is fixedly mounted on the relevant attaching equipment, and the guide wheel 2 is adjusted so that the size of the guide member 21 facing the side of the material to be attached meets the processing requirements.

[0070] Since the guide wheel 2 is fixedly mounted on the module body 1, the guide wheels 2 of different sizes can be adjusted to move to the processing position by rotating the module body 1. At this time, the module body 1 can be arranged to be mounted on the relevant attachment device through a bearing so as to rotate relative to the attachment device.

[0071] In other embodiments, the guide wheel 2 may be configured to rotate around the axis of the module body 1 .

[0072] See also Figure 3 , Figure 3 A schematic cross-sectional structure diagram of the conveying guide module 10 provided in an embodiment of the present application.

[0073] The module body 1 includes a guide limiter and a mounting member 13, wherein the guide limiter includes a fixedly connected mounting shaft 11 and a limiter cover 12. The mounting shaft 11 is used to mount the module body 1 on an attachment device. The limiter cover 12 is located at one end of the mounting shaft 11 axially away from the attachment device. The mounting member 13 is sleeved on the mounting shaft 11 and can be slidably connected to the mounting shaft 11 along the axial direction of the mounting shaft 11, and move closer to or farther away from the limiter cover 12. At this time, the limiter cover 12 can limit the axial movement of the mounting member 13 on the mounting shaft 11 within a certain range. All guide wheels 2 are mounted on the mounting member 13.

[0074] Specifically, the limiting cover 12 can be fixedly connected to the mounting shaft 11 by fasteners such as bolts.

[0075] In order to ensure that the guide wheel 2 is located on the outer peripheral side of the module body 1, a through hole 1302 is provided on the above-mentioned mounting member 13, and the straight line where the axis of the through hole 1302 is located coincides with the straight line where the axis of the mounting member 13 is located.

[0076] The mounting member 13 is sleeved on the mounting shaft 11 through the through hole 1302 , and all the guide wheels 2 are arranged in a ring-shaped manner around the outer circumference of the mounting shaft 11 .

[0077] In order to further achieve the position-limiting fixation of the mounting member 13, the above-mentioned position-limiting cover 12 is provided with a first position-limiting member 121 on one side surface facing the mounting member 13. The number of the first position-limiting members 121 is the same as the number of the guide wheels 2. The mounting member 13 is provided with a plurality of second position-limiting members 1301 which are matched one by one with the first position-limiting members 121. When the first position-limiting member 121 is connected to the second position-limiting member 1301, the mounting member 13 is position-limitingly matched with the position-limiting cover 12; when the first position-limiting member 121 is separated from the second position-limiting member 1301, the mounting member 13 can rotate around the axis relative to the position-limiting cover 12.

[0078] It should be noted that when the first limiting member 121 is connected to the second limiting member 1301, the limiting cover 12 can not only limit the mounting member 13 in the axial direction, but also limit and fix the mounting member 13 in the circumferential direction. At this time, the mounting member 13 can and can only move relative to the limiting cover 12 along the axial direction toward the side away from the limiting cover 12. In order to prevent the mounting member 13 from moving relative to the limiting cover 12, an elastic member 14 is further provided between the above-mentioned mounting member 13 and the mounting shaft 11. The elastic member 14 is used to provide a force for the mounting member 13 to move toward the position where the limiting cover 12 is located, so as to ensure that under the condition of no external force, the mounting member 13 can be pushed by the elastic member 14 to contact the surface of the limiting cover 12, and maintain contact with the limiting cover 12 through the first limiting member 121 and the second limiting member 1301.

[0079] Specifically, the elastic member 14 is sleeved on the mounting shaft 11 and contacts the mounting member 13 .

[0080] See also Figure 3 The inner diameters of the through holes 1302 formed on the mounting member 13 are different at different positions in the axial direction.

[0081] Specifically, along the axial direction of the mounting member 13, the through hole 1302 includes a first through hole 13021 and a second through hole 13022, wherein the first through hole 13021 is located on a side of the mounting member 13 close to the limit cover 12. The inner diameter of the first through hole 13021 is smaller than the inner diameter of the second through hole 13022, so that a step surface 13023 is formed between the first through hole 13021 and the second through hole 13022. Accordingly, when the mounting shaft 11 and the mounting member 13 are assembled together, an abutment portion 111 that can be arranged opposite to the step surface 13023 is provided on the mounting shaft 11. Along the axial direction of the mounting shaft 11, the two ends of the elastic member 14 abut against the abutment portion 111 of the mounting shaft and the step surface 13023 of the mounting member 13, respectively, so as to apply a thrust to the mounting member 13 to move toward the limit cover 12 and maintain a clamping connection with the limit cover 12.

[0082] Exemplarily, the elastic member 14 is a spring, which is sleeved on the mounting shaft 11. At this time, one end of the spring extending toward the mounting member 13 can abut against the step surface 13023, and the other end abuts against the abutment portion 111 on the side of the mounting shaft 11 close to the mounting member 13.

[0083] Specifically, one end of the mounting shaft 11 axially away from the limiting cover 12 protrudes toward the circumference to form a protruding structure similar to a ring, and the protruding structure is the abutting portion 111. The surface of the abutting portion 111 facing the mounting member 13 is used to abut against the elastic member 14 and provide a force to push and reset the mounting member 13.

[0084] In order to further improve the connection firmness between the mounting member 13 and the mounting shaft 11 and prevent the mounting member 13 from shaking relative to the mounting shaft 11, the first through hole 13021 is arranged to be in contact with the mounting member 13 and to be slidably matched.

[0085] When it is necessary to adjust and switch the guide wheel 2 located on the peripheral side of the module body 1, a force can be applied to the mounting member 13 in the direction away from the limiting cover 12. Under the action of external force, the mounting member 13 squeezes the elastic member 14 and moves in the direction away from the limiting cover 12. At this time, the first limiting member 121 and the second limiting member 1301 are separated, and the elastic member 14 is in an extruded deformation state. While keeping the first limiting member 121 and the second limiting member 1301 separated, a rotational force rotating around the axis is applied to the mounting member 13, and the mounting member 13 rotates and drives the guide wheel 2 to rotate synchronously around the axis until the required guide wheel 2 rotates to the working position, and then the external force is removed. Under the action of the elastic force provided by the elastic member 14, the mounting member 13 moves toward the side of the limiting cover 12, and the first limiting member 121 cooperates with the second limiting member 1301 to achieve limiting fixation of the mounting member 13. The switching of the guide wheel 2 is completed.

[0086] See also Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the limit cover 12 in the conveying guide module 10 provided in an embodiment of the present application. Figure 5 A schematic diagram of the structure of the mounting member 13 in the conveying guide module 10 provided in an embodiment of the present application.

[0087] In some embodiments, the first limiting member 121 formed on the limiting cover 12 is a positioning groove, and correspondingly, the second limiting member 1301 formed on the mounting member 13 is a positioning protrusion matched with the surface of the positioning groove.

[0088] In other similar embodiments, the first limiting member 121 may also be adjusted to be a positioning protrusion, and the second limiting member 1301 may be a positioning groove matching the surface shape of the positioning protrusion.

[0089] The number of the first limit members 121 is consistent with the number of the guide wheels 2. Exemplarily, the number of the first limit members 121 and the number of the guide wheels 2 are both 6.

[0090] See also Figure 4 and Figure 5 The first limiting member 121 is a strip-shaped groove extending radially outward. The number of the first limiting members 121 formed on the limiting cover 12 is six and is evenly arranged in a ring shape. The second limiting member 1301 is a strip-shaped protrusion extending radially outward. The number of the second limiting members 1301 formed on the mounting member 13 is six and is arranged one-to-one with the first limiting members 121.

[0091] In some embodiments, see Figure 1 and Figure 2 , the radial dimension of the first stopper 121 is smaller than the radial dimension of the second stopper 1301. In other similar embodiments, the radial dimension of the first stopper 121 may be set to be consistent with the radial dimension of the second stopper 1301, or the radial dimension of the first stopper 121 may be set to be larger than the radial dimension of the second stopper 1301. The embodiment of the present application does not limit the above dimensions.

[0092] In some embodiments, the straight line where the axial direction of the guide wheel 2 is located is parallel to the straight line where the installation axis 11 is located.

[0093] In this embodiment, the mounting member 13 is a hollow columnar structure, one end of which protrudes outwardly in the circumferential direction to form a mounting plate 131 for mounting the guide wheel 2. The mounting plate 131 is evenly provided with positioning grooves 1311 in a circular shape, which are not less than the number of the guide wheels 2. All guide wheels 2 can be fixedly mounted on the mounting plate 131 through the positioning grooves 1311.

[0094] Specifically, the guide wheel 2 can be fixedly connected to the mounting plate 131 by means of bolts or the like. At this time, a screw hole for fixed connection with bolts or the like is provided on the guide wheel 2, and a corresponding threaded hole structure is also formed on the positioning groove 1311.

[0095] Generally speaking, the number of the positioning grooves 1311 is the same as the number of the guide wheels 2 and they are arranged in a one-to-one correspondence. In some special cases, the guide wheels 2 are not completely installed, and some of the installation grooves are vacant.

[0096] See also Figure 5 The mounting member 13 further includes a connecting member 132 and a clearance plate 133. The mounting plate 131 and the clearance plate 133 are arranged opposite to each other, and the connecting member 132 connects the mounting plate 131 and the clearance plate 133. The clearance plate 133 is located on a side of the mounting plate 131 close to the limiting cover 12, and a second limiting member 1301 is provided on a side of the clearance plate 133 facing away from the mounting plate 131.

[0097] Specifically, the through hole 1302 passes through the mounting plate 131 , the connecting member 132 and the clearance plate 133 in sequence, so that the limiting cover 12 and the mounting shaft 11 pass through the mounting member 13 and are fixedly connected.

[0098] In order to reduce the difficulty of installing the guide wheel 2 on the mounting plate 131, in some embodiments, a clearance gap 1331 is provided in the area of ​​the clearance plate 133 opposite to the positioning groove 1311. The operator can install and remove the guide wheel 2 through the clearance gap 1331.

[0099] The above disassembly operation can be used to replace the guide wheel 2. For example, after a certain period of use, the guide wheel 2 reaches its service life, or the wear degree of the guide wheel 2 has reached the scrapping / replacement / repair requirements, and it needs to be removed from the mounting plate 131. Correspondingly, when it is necessary to replace the guide wheel 2 with other attachment precision or update the guide wheel 2, the newly replaced guide wheel 2 can be installed in the controlled mounting groove on the mounting plate 131.

[0100] See also Figure 2 , along the axial direction of the module body 1 , the projection range of the allowance gap 1331 covers the projection range of the guide wheel 2 .

[0101] The surface shape of the clearance gap 1331 should be able to allow the guide wheel 2 to pass through, or be consistent with the surface shape of the circumferential outer wall of the guide wheel 2, so as to ensure that the guide wheel 2 can be smoothly fixed on the installation groove along the axial direction through the clearance gap 1331.

[0102] Considering that the guide member 21 on different guide wheels 2 has different sizes. In order to facilitate the operator to intuitively and quickly understand the current guide wheel 2 size to avoid poor processing, the side of the limit cover 12 facing away from the mounting member 13 is provided with a mark 122, please refer to Figure 1 and Figure 2 When the mounting member 13 is connected to the limiting cover 12 through the first limiting member 121 and the second limiting member 1301 , the mark 122 can point to a certain clearance gap 1331 .

[0103] The corresponding guide member 21 parameter of the guide wheel 2 is marked on the side of the guide wheel 2 pointing to the clearance gap 1331. Therefore, the operator can easily confirm the attachment size corresponding to the ACF guide wheel 2 in the current conveying guide module 10 by checking the number pointed to by the mark 122.

[0104] Specifically, the mark 122 may be a triangular structure, with a sharp end pointing to the radial outside of the limiting cover 12 .

[0105] When the conveying guide module 10 is in operation, the guide member 21 formed on the outer side wall of the guide wheel 2 is used to guide the conveying direction of the material to be attached.

[0106] It is understandable that the conveying guide module 10 provided in the embodiment of the present application does not need to be disassembled to replace the guide wheel 2. Therefore, the wear problem of the guide wheel 2 caused by disassembly can be effectively reduced, and there will be no problem that the size of the guide wheel 2 needs to be calibrated and adjusted due to disassembly, thereby affecting the processing efficiency. Compared with the related art, the conveying guide module 10 provided in the present embodiment can realize the rapid and lossless switching of the guide wheel 2, which can not only significantly shorten the time required for switching the guide wheel 2 and improve the processing efficiency, but also improve the working accuracy of the guide wheel 2 to a certain extent. Taking ACF attachment as an example, its accuracy can be improved from 0.20mm to 0.08mm, which can better adapt to the development trend of electronic equipment, meet the bonding processing requirements of ultra-thin frame display panels, and help improve the processing yield of display panels.

[0107] Based on the same inventive concept, the embodiment of the present application further provides an operating method, which is applicable to the above-mentioned conveying guide module 10. The operator can use the operating method to operate the conveying guide module 10 and / or assemble the conveying guide module 10.

[0108] See also Figure 6 The operation method includes a method for using the conveying guide module 10, and the method for using the conveying guide module 10 includes the following steps:

[0109] Step S101, pushing the mounting member 13 to squeeze the elastic member 14, so that the mounting member 13 is separated from the limiting cover 12;

[0110] Step S102, rotating the mounting member 13 to switch the guide wheel 2 toward the working position;

[0111] Step S103 , releasing the mounting member 13 , so that the elastic member 14 pushes the mounting member 13 to move axially and engage with the limiting cover 12 .

[0112] In step S101, by applying external force to the mounting member 13, the mounting member 13 can overcome the pressing force provided by the elastic member 14 and compress the elastic member 14. In this process, the mounting member 13 moves toward the side away from the limiting cover 12 until the mounting member 13 is completely separated from the limiting cover 12.

[0113] The external force applied to the mounting member 13 can be manually pushed by an operator or pushed by a corresponding mechanical structure, which is not limited in this embodiment. Taking the first limiting member 121 provided on the limiting cover 12 as an example, the first limiting member 121 can be engaged with the second limiting member 1301 to achieve the limitation of the mounting member 13 in the circumferential direction.

[0114] After the mounting member 13 is separated from the limiting cover 12, step S101 ends and step S102 is executed to rotate the mounting member 13 to adjust the position of the guide wheel 2 in the circumferential direction of the guide limiting member until the guide wheel 2 matching the material to be attached faces the working position.

[0115] The mounting member 13 can rotate relative to the limiting cover 12 and the mounting shaft 11 around the axis of the mounting shaft 11 under the action of external force, and drive the guide wheel 2 mounted on the mounting member 13 to rotate synchronously around the axis of the mounting shaft 11 .

[0116] Similarly, the force used to push the mounting member 13 to rotate can be manually pushed by an operator or pushed by a corresponding mechanical structure. The rotation angle and rotation speed of the mounting member 13 can be adaptively adjusted according to actual needs, and the purpose is to switch the guide wheel 2 on the mounting member 13 toward the working position so that the guide wheel 2 facing the working position finally matches the size of the material to be attached.

[0117] In some embodiments, the material to be attached can be arranged directly below the mounting member 13, that is, the working position is directly below the mounting member 13. Accordingly, the guide wheel 2 for cooperating with the material to be attached should also be arranged toward the working position, that is, toward directly below the mounting member 13.

[0118] When the size of the material to be attached changes, the mounting member 13 needs to be rotated by the above-mentioned method to switch the position of the guide wheel 2, so that the guide wheel 2 matching the size of the material to be attached rotates to the working position.

[0119] After the appropriate guide wheel 2 rotates to the working position, step S102 is completed, and step S103 is executed to release the mounting member 13. The elastic release energy compressed and stored in step S101 by the elastic member 14 is released, and can act on the mounting member 13 and push the mounting member 13 to move toward the limit cover 12, so that the second limit member 1301 formed on the mounting member 13 and the limit cover 12 is limited and matched with the first limit member 121. At this time, the mounting member 13 is connected to the limit cover 12 and is circumferentially locked relative to the mounting shaft 11 under the action of the circumferential limit provided by the limit cover 12.

[0120] At this point, guide wheel 2 has completed switching.

[0121] See also Figure 7 The operation method includes an installation method of the conveying guide module 10, and the installation method includes the following steps:

[0122] Step S201, obtaining the guide wheel 2 and the module body 1, installing the guide wheel 2 on the module body 1 and adjusting the guide members 21 of all the guide wheels 2 to face away from the middle of the module body 1;

[0123] Step S202 , calibrating the positions of all guide wheels 2 installed on the module body 1 .

[0124] In step S201, the guide wheel 2 and the module body 1 may be installed according to actual conditions.

[0125] Exemplarily, the module body 1 includes a mounting shaft 11 , a limiting cover 12 , a mounting member 13 and an elastic member 14 .

[0126] In some embodiments, the guide wheel 2 can be installed on the mounting member 13 first, and then the elastic member 14 and the mounting member 13 are sequentially mounted on the mounting shaft 11, and finally the limit cover 12 is installed on the mounting shaft 11 to complete step S201.

[0127] In other similar embodiments, it is also possible to first sleeve the elastic member 14 and the mounting member 13 on the mounting shaft 11, then install the limit cover 12 on the mounting shaft 11, and finally install the guide wheel 2 on the mounting member 13 to complete step S201.

[0128] Both of the above two methods can implement step S201.

[0129] After step S201 is completed, step S202 is executed. In step S202, the operator can calibrate the position of the guide wheel 2 by visual observation or by mechanical equipment detection.

[0130] Specifically, the calibration standard of the guide wheel 2 is whether the axis of the guide wheel 2 and the axis of the mounting member 13 remain horizontal.

[0131] Based on the same inventive concept, an embodiment of the present application further provides an attachment device, comprising any one of the conveying guide modules 10 described above.

[0132] In some embodiments, there are two conveying guide modules 10 arranged opposite to each other, and the guide members 21 of the two conveying guide modules 10 are opposite to each other. The material to be attached is located between the two conveying guide modules 10 arranged opposite to each other, and can be conveyed to the next station under the guidance of the two guide members 21.

[0133] The attaching device provided in the embodiment of the present application includes the above-mentioned conveying guide module 10, so the attaching device at least includes the beneficial effects of the above-mentioned conveying guide module 10. The specific effects are described above and will not be repeated here.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
