Description

Technical Field

[0001] The present application relates to the technical field of display panel manufacturing, and in particular to a COF attaching device and an attaching method. Background Art

[0002] In display panel manufacturing, COF (Chip On Film) is a key component connecting driver chips to glass substrates. Its bonding accuracy directly impacts the ultimate performance of the display panel. With the continuous advancement of display technology, glass substrates are evolving towards larger sizes and higher precision. Furthermore, to meet diverse display driver requirements, a single panel often requires the bonding of two or more COFs of varying sizes. This process requirement presents technical challenges for traditional COF bonding equipment.

[0003] For example, the compatibility of COFs with multiple specifications is insufficient: the traditional single-attachment pressure head structure requires frequent replacement of fixtures. Different COF sizes require different temperatures, pressures, and ACF attachment lengths, making it difficult to adjust the single pressure head in real time. Deformation control of large-sized glass substrates is difficult: The bonding area is the terminal area of ​​the glass substrate, but the glass substrate is too large, which causes the back of the terminal area to warp during bonding, affecting the bonding accuracy; Collaborative operation conflicts among multiple attachment units: When two attachment heads work in parallel, the risk of motion interference is high, and traditional mechanical anti-collision solutions reduce the effective working range. Summary of the Invention

[0004] The present invention proposes a COF attachment device and attachment method to solve the technical problems existing in the prior art, such as insufficient compatibility of COFs of multiple specifications, difficulty in controlling the deformation of large-sized glass substrates, resulting in low attachment accuracy and conflicts in the collaborative operations of multiple attachment units.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is: The present invention provides a COF attaching device for attaching COFs of different sizes on a large-sized glass substrate, comprising: a bracket, a first attaching unit and a second attaching unit being symmetrically provided on the back of the bracket, and an alignment unit being provided on the front of the bracket; Pressing unit; A support unit is provided below the pressing unit and includes a support platform and a support platform driving unit. A plurality of support suction cups are provided on the support platform at intervals. glass platform units; The first attaching platform and the second attaching platform are respectively provided below the first attaching unit and the second attaching unit; The glass substrate is placed on the glass platform, the alignment unit collects the position of the glass substrate, and the glass platform unit drives the glass substrate so that the part where the COF needs to be attached is placed on the support platform; the pressing unit can press the glass substrate toward the support platform in a downward manner so that the supporting suction cup adsorbs the glass substrate; the first attaching unit and the second attaching unit can cooperate either simultaneously or alternately to attach the COF to the glass substrate.

[0006] Furthermore, the bracket includes more than two groups of columns, and beams are fixed on the columns. The columns and the beams are connected by an adjustment component, and the adjustment component is used to adjust the horizontality of the beams.

[0007] Furthermore, the pressing unit is arranged between the first attaching unit and the second attaching unit, and includes a pressing driving part, a pressing suction cup driven by the pressing unit, and a pressing connecting plate, and the pressing connecting plate is fixed to the bottom of the beam; the pressing suction cup is in a non-vacuum state.

[0008] Furthermore, the support platform includes a pressing area, which is arranged between the two supporting suction cups. The pressing suction cups are pressed toward the pressing area, and the supporting suction cups adsorb the glass substrate.

[0009] Furthermore, the glass platform unit is arranged in front of the supporting unit, and includes a platform transverse driving part and a glass platform driving part; a platform bottom plate is fixed above the platform transverse driving part, and a first sensing area and a second sensing area and a sensing element moving within the range of the first sensing area and the second sensing area are provided on the platform bottom plate. When the sensing element does not sense, the glass platform can reset its origin.

[0010] The attachment method based on the COF attachment device includes the following steps: S1. Glass substrate loading: The glass platform moves to the receiving position, the transport arm places the glass substrate on the glass platform, and the glass platform absorbs the glass substrate and moves to the camera position of the alignment unit; S2. Glass photography: The alignment unit takes photos of the marking points on the glass substrate, and the glass platform moves to the attachment position. The rear of the terminal area of ​​the glass substrate is placed on the support platform. S3. Positioning the glass substrate: The pressing suction cup moves vertically through the pressing driving unit and presses the rear of the terminal area, and the supporting suction cup of the supporting platform adsorbs the rear of the terminal area; S4, attachment operation allocation: the alignment unit takes pictures of all COFs on the glass substrate to identify all COF sizes, and feeds back the different lengths of the COFs to the first attachment unit and the second attachment unit respectively; S5. COF attachment: The first attachment unit and the second attachment unit distribute work, the first attachment platform moves synchronously with the first attachment unit, and the second attachment platform moves synchronously with the second attachment unit to complete the attachment action.

[0011] Furthermore, the first attaching unit and the second attaching unit perform an origin reset operation before attaching glass substrates of different specifications.

[0012] Furthermore, after the first attaching unit and the second attaching unit move to the first origin position and the second origin position, they move in the opposite direction to the collision position, and calculate the maximum travel of the first attaching unit and the second attaching unit to the collision position, which is recorded as the first distance; the target distance moved by the first attaching unit is the second distance, and the target distance moved by the second attaching unit is the third distance; when and only when the sum of the second distance and the third distance is less than the first distance, the first attaching unit and the second attaching unit perform the attaching action at the same time.

[0013] Furthermore, when the sum of the second distance and the third distance is greater than the first distance, one of the first attaching unit and the second attaching unit performs the attaching action first, and the other waits or moves to the avoidance position until one of its attaching actions is completed before performing the attaching action.

The pressing unit and the supporting unit form a "press first, then adsorb" synergy to avoid warping of the glass substrate due to adsorption, ensuring the flatness of the attachment. The attachment method solves the attachment process for COFs of different sizes, avoids interference, and is compatible with the attachment of COFs of the same specifications, thereby improving efficiency.

[0018] Please also refer to Figure 1 、 Figure 2A COF attaching device for attaching COFs 200 of different sizes to a large-sized glass substrate 100 comprises: a bracket 1, with a first attaching unit 2 and a second attaching unit 3 symmetrically disposed on the back of the bracket 1, and an alignment unit 9 disposed on the front of the bracket 1; a pressing unit 4 disposed between the first attaching unit 2 and the second attaching unit 3, comprising a pressing drive 41 and a pressing suction cup 42 driven thereby; a support unit 5 disposed below the pressing unit 4, comprising a support platform 52 and a support platform drive 54, with multiple support suction cups 51 spaced apart on the support platform 52; a glass platform unit 6 disposed in front of the support unit 5, comprising a glass platform 62 for supporting the glass substrate 100, a platform transverse drive 63, and a glass platform drive 61; a first attaching platform 7 and a second attaching platform 8, respectively located below the first attaching unit 2 and the second attaching unit 3. The first attaching unit 2 and the second attaching unit 3 are symmetrically disposed on the back of the bracket 1, and the alignment unit 9 is disposed on the front of the bracket 1. This layout cleverly addresses the pain points of traditional devices. Because the glass platform 62 corresponding to the large-sized glass substrate 100 is large and occupies a large portion of the upper frame, the ACF used for attachment requires frequent replacement (perhaps every hour during mass production). Conventional equipment places the attachment unit on the front. Since the glass platform 62 is located in front of the bracket 1, the large size of the glass platform 62 results in a very large front depth. With this conventional front-mounted attachment unit, operators must at least pass through the glass platform unit 6 to change the ACF, requiring the equipment to be paused for access, significantly impacting efficiency. In contrast, this equipment places the first and second attachment units on the back, allowing operators to change ACFs instantly while the equipment is running, achieving continuous operation and significantly improving production efficiency.

[0019] The bracket 1 serves as the basic support structure of the equipment and is composed of two or more groups of columns 11. A beam 12 is fixed on the column 11, and the column 11 and the beam 12 are connected by an adjustment component 13. The adjustment component 13 can accurately adjust the horizontality of the beam 12. The adjustment component 13 can be a combination of screws, nuts, and bolts. The bolts connect the beam 12 to the column 11. When the horizontal position of the beam 12 is too high or too low, the corresponding bolts in the adjustment component 13 are rotated forward or backward to ensure that the beam 12 is in a horizontal state, providing a basis for the stable operation of other units. In order to meet the attachment stroke of the first attachment unit 2 and the second attachment unit 3, the beam 12 is longer than the traditional bracket 1, and at the same time faces uneven stability and horizontality. By providing four or more groups of adjustment components 13, it is convenient to adjust the overall horizontality of the beam 12 at any time to ensure the stability of the coordinated operation of each unit.

[0020] Please also refer to Figure 3The pressing unit 4 includes a pressing connecting plate, which is fixed to the bottom of the beam 12. A pressing driving unit 41 is fixed on the pressing connecting plate. The pressing driving unit 41 can drive the pressing suction cup 42 to press down the glass substrate 100. Please refer to Figure 4 The support unit 5 is composed of a support platform 52 and a support platform driving unit 54. The support platform driving unit 54 can drive the support platform 52 to move in the longitudinal direction. A plurality of support suction cups 51 are arranged at intervals on the support platform 52. These support suction cups 51 are used to absorb the support area of ​​the glass substrate 100, that is, the rear of the terminal area, to enhance the stability of the glass substrate 100 during attachment. The support platform 52 also includes a pressing area 53. The pressing area 53 is located between the two support suction cups 51. The pressing suction cup 42 will accurately press against the pressing area 53. After the support suction cup 51 completely absorbs the support area of ​​the glass substrate 100, the pressing suction cup 42 is reset.

[0021] Please also refer to Figure 5 The glass platform unit 6 includes a glass platform 62 that supports the glass substrate 100 and a platform transverse drive unit 63 that drives the glass platform 62 in transverse motion. A platform base plate 64 is fixed above the platform transverse drive unit 63. A glass platform drive unit 61 is mounted on the platform base plate 64 to drive the glass platform 62 in longitudinal and rotational motion. These drive components work together to achieve flexible movement of the glass platform 62 in multiple directions, meeting the requirements for alignment and different attachment positions between the glass substrate 100 and the COF 200. Specifically, in this embodiment, the pressing suction cup 42 is preferably in a non-vacuum state. Its function is to first press the glass substrate 100, and then cooperate with the supporting suction cup 51 for suction. This prevents the glass substrate 100 from being locally warped or uneven when the supporting suction cup 51 is sucked, thereby ensuring the flatness of the glass substrate 100. When the glass platform 62 absorbs the glass substrate 100 and moves it above the supporting platform 52, the supporting platform drive unit 54 drives the supporting platform 52 to move vertically, so that the rear of the terminal area of ​​the glass substrate 100 rests on the supporting platform 52. At this time, the pressing suction cup 42 is pressed downward by the pressing drive unit 41, and the supporting suction cup 51 absorbs the glass substrate 100, and the pressing suction cup 42 returns to its original position, ensuring that each supporting suction cup 51 firmly holds the glass substrate 100.

[0022] In addition, the platform base plate 64 is provided with a first sensing area 641, a second sensing area 642, and a sensing element 643 that moves within these two sensing areas. The sensing element 643 can monitor the range of motion of the glass platform 62 in real time. Because the glass platform 62 is relatively large, the position of the glass platform 62 is uncertain each time the glass platform 62 resets its origin. At this time, the origin reset is prone to collision or interference with other structures. To ensure that the glass platform 62 resets its origin within a safe and reasonable range each time, the first sensing area 641 and the second sensing area 642 are respectively provided on both sides. That is, when the sensing element 643 does not sense the first sensing area 641 or the second sensing area 642, the reset action can be performed, ensuring that the reset action is performed within a safe range to avoid collision and interference.

[0023] In addition, the present application also discloses a method for attaching a COF based on the above-mentioned COF attaching device, which specifically includes the following steps: S1. The glass platform 62 moves to the receiving position, and the conveying arm places the glass substrate 100 on the glass platform 62. The glass platform 62 adsorbs the glass substrate 100 and moves to the photographing position. Specifically, in this step, the glass platform 62 moves to the receiving position under the coordinated action of the platform transverse driving unit 63 and the glass platform driving unit 61. The conveying arm places the glass substrate 100 on the glass platform 62. The glass platform 62 adsorbs the glass substrate 100 through its own adsorption device, and then the glass platform 62 moves to the photographing position. S2. The alignment unit 9 photographs and records the marked points on the glass substrate 100. The glass platform 62 moves to the attachment position, and the rear end of the terminal area of ​​the glass substrate 100 is placed on the support platform 52. Specifically, in this step, the alignment unit 9 photographs and records the marked points on the glass substrate 100. The controller analyzes and processes the captured images, and obtains the position information of the glass substrate 100 based on the coordinates of the marked points. The glass platform 62 then moves to the attachment position, and the rear end of the terminal area of ​​the glass substrate 100 is placed on the support platform 52.

[0024] S3. The pressing suction cup 42 moves vertically through the pressing driving part 41 and presses the rear of the terminal area, and the supporting suction cup 51 of the supporting platform 52 adsorbs the rear of the terminal area. Specifically, in this step, the pressing driving part 41 drives the pressing suction cup 42 to move vertically, and the pressing suction cup 42 presses the rear of the terminal area, that is, the position directly above the pressing area 53 of the supporting platform 52. The pressing suction cup 42 will accurately press toward the pressing area 53, and then the supporting suction cup 51 on the supporting platform 52 adsorbs the rear of the terminal area. Through the dual effects of pressing first and then adsorbing, warping around the terminal area of ​​the glass substrate 100 is prevented, ensuring that the terminal area of ​​the glass substrate 100 remains stable during the attachment process.

[0025] S4: The alignment unit 9 photographs all COFs 200 on the glass substrate 100 to identify their sizes and feeds back the different lengths of the COFs 200 to the first attaching unit 2 and the second attaching unit 3. Specifically, in this step, the alignment unit 9 photographs all COFs 200 on the glass substrate 100 to accurately obtain the length information of the COFs 200 and feeds back the information to the first attaching unit 2 and the second attaching unit 3, respectively. The first attaching unit 2 and the second attaching unit 3 then coordinate and allocate tasks. S: The first attaching unit 2 and the second attaching unit 3 allocate tasks, the first attaching platform 7 moves synchronously with the first attaching unit 2, and the second attaching platform 8 moves synchronously with the second attaching unit 3 to complete the attaching operation. Specifically, in this step, COF200 of different lengths can be set on the first attaching unit 2 and the second attaching unit 3, or COF200 of equal length can be set; the first attaching unit 2 and the second attaching unit 3 distribute work according to the received COF200 length information, the first attaching platform 7 moves synchronously with the first attaching unit 2, and the second attaching platform 8 moves synchronously with the second attaching unit 3 to jointly complete the COF200 attachment action. When the attached COF200 is of the same length and multiple COF200s are attached, Figure 6 As shown, for example, when a COF200 is attached on one side and the length is the same, the COF200 is marked with serial numbers 1 to 10 from left to right. After the COF attaching equipment performs S1-S4 actions, the first attaching unit 2 and the second attaching unit 3 are reset to the origin. Specifically, the first attaching unit 2 and the second attaching unit 3 first move to the first origin position and the second origin position, which are respectively located on both sides of the bracket 1, and then each moves in the opposite direction to the collision position. In the process of moving to the collision position, the first attaching unit 2 and the second attaching unit 3 can be moved slowly until they reach the maximum stroke of the collision position and recorded as the first distance, i.e., D1. When the operation officially starts, the first attaching unit 2 starts attaching COF200 with serial number 1, and the second attaching unit 3 starts attaching COF200 with serial number 2. The distance moved by the first attaching unit 2 each time is set as the second distance, i.e. D2, and the distance moved by the second attaching unit 3 each time is set as the third distance, i.e. D3. In order to avoid interference between the first attaching unit 2 and the second attaching unit 3 during the operation, the sum of the second distance and the third distance is always less than the first distance, i.e. D2+D3<D1; and so on, the operation is alternated in sequence. When the first attaching unit 2 attaches COF200 with serial number 2, the second attaching unit 3 attaches COF200 with serial number 7 to ensure the attachment efficiency.

[0026] When the attached COF200 lengths are different, such as Figure 7As shown, when COFs 200 of different lengths are arranged in an ABABAB... format, the COFs 200 are also numbered 1 to 10. In this case, the principle of D2+D3<D1 is maintained, and two methods can be used. When D2+D3<D1 is satisfied, the first attaching unit 2 attaches COF 200 numbered 1 while the second attaching unit 3 attaches COF 200 numbered 2. When the first attaching unit 2 attaches COF 200 numbered 3 while the second attaching unit 3 attaches COF 200 numbered 4, and so on. However, if D2+D3>D1 occurs when the first attaching unit 2 attaches COF200 with sequence number 1 and the second attaching unit 3 attaches COF200 with sequence number 2, then the first attaching unit 2 is executed first, and the second attaching unit 3 moves to the avoidance position and waits. After the first attaching unit 2 completes the action of attaching COF200 with sequence number 1, the second attaching unit 3 enters the attaching station to attach COF200 with sequence number 2. This cycle continues until the attachment is completed to avoid interference.

[0027] When the attached COF200 lengths are different, such as Figure 8 As shown, when the layout of COF200 of different lengths is AAAAABBBBB..., the COF200 are also marked with serial numbers 1 to 10. At this time, if D2+D3<D1, the first attaching unit 2 attaches COF200 with serial number 1 while the second attaching unit 3 attaches COF200 with serial number 6, and the attachment is carried out in a cyclic and progressive manner according to the serial number to ensure efficient coordination. However, if D2+D3>D1 occurs when the first attaching unit 2 attaches COF200 with serial number 1 and the second attaching unit 3 attaches COF200 with serial number 6, then the first attaching unit 2 is executed first, and the second attaching unit 3 moves to the avoidance position to wait. After the first attaching unit 2 completes the action of attaching COF200 with serial number 1, the second attaching unit 3 enters the attaching station to attach COF200 with serial number 6, and the cycle continues until the attachment is completed to avoid interference.

[0028] When the attached COF200 lengths are different, such as Figure 9As shown, when the COF200 of different lengths is arranged in the form of AABBAABB..., the COF200 are also marked with serial numbers 1 to 10. In this case, if D2+D3<D1, the first attaching unit 2 attaches the COF200 with serial number 1, and the second attaching unit 3 attaches the COF200 with serial number 3, ensuring that the serial numbers of the attached COF200 are progressive and ensuring operational continuity. However, if D2+D3>D1 occurs when the first attaching unit 2 attaches the COF200 with serial number 1 and the second attaching unit 3 attaches the COF200 with serial number 3, then the first attaching unit 2 is prioritized and the second attaching unit 3 moves to a waiting position. After the first attaching unit 2 completes attaching the COF200 with serial number 1, the second attaching unit 3 enters the attaching station to attach the COF200 with serial number 3. This cycle continues until the attachment is completed to avoid interference.

[0029] After one side is attached, if the other side of the same glass substrate 100 needs to be attached, the glass platform 62 only needs to be rotated to a set angle by the glass platform driving unit 61 so that the other side is at the attachment position, and the above operation is repeated.

[0030] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
