Description

Technical Field

[0001] This invention relates to the field of display panel picking technology, and in particular to a display panel slicing picking head, a four-station picking device, and a picking method. Background Technology

[0002] In the cutting production line of TFT-LCD, OLED and other display panels, the processes of feeding, cutting, breaking, sorting and unloading are carried out in sequence. Among them, the breaking process is the key to whether the display panel can be automatically separated. Before breaking, the cutting machine's blade wheel cuts across the display panel and leaves a cutting line on its surface, while simultaneously creating a crack inside the display panel. During breaking, the breaking machine applies pressure from the back of the display panel at the position corresponding to the cutting line, increasing the stress at the crack in the display panel, thereby accelerating crack propagation and shortening the time required for the display panel to completely separate. After breaking, the pick-up head picks up the display panel and transports it to the next process.

[0003] In existing technologies, some display panels consist of two glass substrates with a frame adhesive between them, while others have a PET film glued to their surface. These panels often retain adhesive residue after breakage, making complete separation impossible. Therefore, for these panels, manual separation is typically required to ensure a complete break before a pick-up head transfers the panel to the next process. This method requires manual intervention and cannot meet the needs of fully automated operations.

[0004] In summary, there is an urgent need for a pickup head that can achieve fully automated operation. Summary of the Invention

[0005] To overcome the technical shortcomings of existing pickup heads that cannot be adapted to fully automated operations on some display substrates, this invention provides a display panel slicing pickup head, a four-station pickup device, and a pickup method.

[0006] The display panel slicing pickup head provided by the present invention includes: Mounting bracket; A rotary drive component, the fixed part of which is connected to the mounting bracket and the axis of the output part is arranged vertically; A rotating disk is mounted on the bottom of the mounting bracket and is connected in a transmission manner to the output part of the rotating drive component; The pickup module includes a mounting plate and an adsorption assembly and an edge pressing assembly, both mounted below the mounting plate. The mounting plate is fixed below the rotating disk. The adsorption assembly includes an adsorption support plate fixed relative to the mounting plate and a vacuum suction cup mounted on the adsorption support plate. The vacuum suction cup has multiple sets and is used to adsorb the edge area of ​​the product. The edge pressing assembly has multiple sets and is arranged one-to-one with the outer edge of the product. The edge pressing assembly includes a lifting drive and a pressing knife. The fixed part of the lifting drive is connected to the mounting bracket and the output part faces downward. The pressing knife is fixed on the output part of the lifting drive and extends along the outer edge of the product. The lifting drive is used to continuously press down on the outer edge of the product during the process of the vacuum suction cup adsorbing the product and lifting it to detach from the edge.

[0007] Furthermore, the lifting drive component is a constant pressure cylinder, and when the constant pressure cylinder extends to its limit stroke position, its free end is lower than the adsorption surface of the vacuum suction cup.

[0008] Furthermore, the display panel slicing pickup head is used to pick up rectangular products, the edge pressing assembly is provided in four sets, and the two opposite edge pressing assemblies are driven to move closer or further away synchronously, the adsorption support plate is provided in two and is respectively fixed on the fixing part of a set of oppositely arranged lifting drive components, the adsorption support plate is a strip plate and extends along the edge of the corresponding product, the vacuum suction cup is provided in four and is respectively located at the two ends of the two adsorption support plates, and the vacuum suction cup can be adjusted along the length direction of the adsorption support plate.

[0009] Furthermore, the fixed parts of the relatively arranged lifting drive components are respectively connected to two nuts on the same bidirectional lead screw pair to achieve synchronous approach or departure.

[0010] Furthermore, the bidirectional lead screw assembly is either manually driven or electrically driven.

[0011] Furthermore, the rotating disk is a quick-change disk, which includes a main disk and a secondary disk. The main disk is rotatably connected to the bottom of the mounting bracket, and the secondary disk is detachably connected to the bottom of the main disk and fixedly connected to the mounting plate.

[0012] Furthermore, the adsorption assembly also includes an auxiliary adsorption head, which is installed below the center of the mounting plate, and the adsorption surface of the auxiliary adsorption head is flush with the adsorption surface of the vacuum suction cup.

[0013] The four-station pickup device provided by the present invention includes: Fixture; The sliding beam has two beams, both extending along the Y direction. Both ends of each sliding beam are slidably connected to the fixed frame, and each sliding beam is driven to slide independently along the X direction. The sliding head has two pairs and is respectively mounted on two sliding beams. Each sliding head is driven to slide along the corresponding sliding beam. Each sliding head is equipped with a Z-axis drive pair. The output of each Z-axis drive pair is equipped with the aforementioned display panel segment pickup head, and the mounting bracket is connected to the output of the corresponding Z-axis drive pair.

[0014] Furthermore, a positioning vision camera is installed on one of the sliding heads of each sliding beam.

[0015] The picking method provided by this invention is based on the aforementioned four-station picking device. If the four sliding heads are defined as A1, A2, B1, and B2, and A1 and A2 are located on the same sliding beam, B1 and B2 are located on the same sliding beam, A1 and B1 are located on the same side in the Y direction, and A2 and B2 are located on the same side in the Y direction, then: For panel slabs that only have a single specification product: If the distance between the two sliding beams is satisfied, the picking columns are equally distributed from X to the middle, and the sliding heads on the two sliding beams pick up synchronously; if the distance between the two sliding beams is not satisfied, synchronous picking of A1 and A2 or synchronous picking of B1 and B2 is preferred. When the distance between the two sliding heads of the same sliding beam is satisfied, the picking rows are equally distributed from Y to the middle, and the sliding heads on the same sliding beam are picked up synchronously; when the distance between the two sliding heads of the same sliding beam is not satisfied, A1 and B1 or A2 and B2 are picked up synchronously first. For panel panels with two or more product specifications: For the single product with the largest quantity, the panel picking method for single-specification products is adopted.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art: The display panel slicing pickup head provided by this invention has an edge-pressing component on the outside of the adsorption component, and the stroke of the edge-pressing component is cleverly designed so that when the adsorption component contacts the product, the lifting drive of the edge-pressing component also presses down on the waste edge of the product but does not reach its limit stroke. When the mounting bracket is driven to lift the adsorption component, the edge-pressing component, and the product as a whole, the output part of the edge-pressing component still maintains the state of pressing down on the waste edge until the product is lifted to the point of detaching from the waste edge, reaching its limit stroke. Finally, the mounting bracket is driven to transfer the product to the next process. This pickup head, by mechanically simulating the action of manual panel slicing, can be adapted to display panels with frame adhesive or PET film attached between two glass substrates, thus making it suitable for fully automated cutting production lines for display panels.

[0017] The four-station pickup device provided by this invention can simultaneously pick up display panel segments using four pickup heads. Each display panel segment pickup head can be moved to any position in the XY plane via the movement of the sliding beam and the sliding head. This allows it to adapt to the full-page layout of various products and has high pickup efficiency.

[0018] The picking method provided by this invention can further improve picking efficiency by limiting the priority order of the picking heads. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0025] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example

[0026] Reference Figures 1 to 6 This embodiment provides a display panel segmentation pickup head, including a mounting bracket 1, a rotation drive 2, a rotating disk 3, and a pickup module 4.

[0027] Among them, mounting bracket 1 is mainly used to provide hardware support for other components.

[0028] Specifically, the structure of mounting bracket 1 is not limited. For example... Figure 1 and Figure 2 As shown, the mounting bracket 1 in this embodiment includes a base plate 11, a vertical plate 12 and two ribs 13. The base plate 11 has clearance holes 111 to facilitate the connection between the rotating disk 3 and the rotating drive component 2.

[0029] The fixed part of the rotary drive 2 is connected to the mounting bracket 1, and the axis of the output part is arranged vertically.

[0030] It is easy to understand that the rotary drive 2 is mainly used to provide rotational motion to the pickup module 4 through the rotary disk 3, so as to meet the angle compensation or placement angle requirements of product pickup.

[0031] Specifically, the structure of the rotary drive component 2 is not limited. For example... Figure 1 and Figure 2 As shown, the rotary drive 2 in this embodiment includes a servo motor 21 and a reducer 22. The reducer 22 is installed below the servo motor 21 and connected to the rotary disk 3.

[0032] The rotating disk 3 is mounted on the bottom of the mounting bracket 1 and is connected to the output of the rotating drive component 2.

[0033] Specifically, the transmission connection between the rotating disk 3 and the output part of the rotating drive 2 is not limited, as long as the output part of the rotating drive 2 can drive the rotating disk 3 to rotate when it rotates, such as a gear pair, a synchronous belt pair, etc.

[0034] Specifically, the structure of the rotating disk 3 is not limited. For example... Figure 2 As shown, the rotary disk 3 in this embodiment is a quick-change disk, which includes a main disk 31 and a secondary disk 32. The main disk 31 is rotatably connected to the bottom of the mounting bracket 1, and the secondary disk 32 is detachably connected to the bottom of the main disk 31. The secondary disk 32 is fixedly connected to the mounting plate 41 of the pickup module 4. The quick-change disk is a mature structure in the field. Its main disk 31 and secondary disk 32 are connected by mechanical and electrical cooperation. Through the device operation interface, one-click quick separation and quick connection can be achieved to replace pickup modules 4 of different specifications, thereby adapting to products of different specifications.

[0035] The pickup module 4 includes a mounting plate 41 and an adsorption assembly 42 and an edge pressing assembly 43, both mounted below the mounting plate 41. The mounting plate 41 is fixed below the rotating disk 3. The adsorption assembly 42 includes an adsorption support plate 421 fixedly disposed relative to the mounting plate 41 and a vacuum suction cup 422 mounted on the adsorption support plate 421. The vacuum suction cup 422 is provided in multiple sets and is used to adsorb the edge area of ​​the product. The edge pressing assembly 43 is provided in multiple sets and is provided one by one with the outer edge of the product. The edge pressing assembly 43 includes a lifting drive 431 and a pressing knife 432. The fixed part of the lifting drive 431 is connected to the mounting bracket 1 and the output part faces downward. The pressing knife 432 is fixed on the output part of the lifting drive 431 and extends along the outer edge of the product. The lifting drive 431 is used to continuously press down on the outer edge of the product during the process of the vacuum suction cup 422 adsorbing the product and lifting it to detach from the edge. During operation, the mounting bracket 1 is driven to lower the adsorption assembly 42 and the edge pressing assembly 43 as a whole. When the vacuum suction cup 422 contacts the edge area of ​​the product, the lifting drive 431 moves to press the pressing knife 432 against the outer waste edge of the product, and the lifting drive 431 has not reached its limit stroke position. When the adsorption assembly 42 completely adsorbs the product, the mounting bracket 1 is driven to raise the adsorption assembly 42 and the edge pressing assembly 43 as a whole. At this time, the output part of the lifting drive 431 still has a relatively downward movement, so that the pressing knife 432 keeps pressing against the waste edge. This causes the product and the waste edge to be pulled vertically relative to each other, thus completely separating them. When the product is separated from the waste edge, the lifting drive 431 reaches its limit stroke position, and then continues to rise with the mounting bracket 1 to detach from the waste edge. Before placing the product in the next process, the lifting drive 431 needs to be retracted to avoid interference between the pressing knife 432 and the product.

[0036] Specifically, the type of lifting drive component 431 is not limited. For example... Figure 1 As shown, the lifting drive component 431 in this embodiment is a constant pressure cylinder, and when the constant pressure cylinder extends to its limit stroke position, its free end is lower than the adsorption surface of the vacuum suction cup 422. It is easy to understand that the constant pressure cylinder needs to be equipped with a solenoid valve 433 during installation to control the up and down movement and maintain constant pressure.

[0037] It should be noted that a pressure switch 424 needs to be configured when installing the vacuum suction cup 422. The pressure switch 424 is used to detect the adsorption pressure of the vacuum suction cup 422. When the adsorption pressure reaches the preset value, it indicates that the adsorption vacuum has been established and outputs an IO signal.

[0038] It is easy to understand that the number and layout of the edge-pressing assembly 43 and the vacuum suction cup 422 should be designed according to the shape of the product. For example, the product targeted in this embodiment is a rectangular product, so there are four sets of edge-pressing assemblies 43 and four vacuum suction cups 422.

[0039] In order to adapt to products of various specifications, this embodiment designs the two sets of pressing components 43 to be driven to move closer or further away synchronously. There are two adsorption support plates 421, which are respectively fixed on the fixing part of a set of lifting drive components 431 arranged opposite to each other. The adsorption support plate 421 is a strip and extends along the edge of the corresponding product. Four vacuum suction cups 422 are located at the two ends of the two adsorption support plates 421 respectively. The vacuum suction cups 422 can be adjusted along the length of the adsorption support plate 421. By moving the two pressing components 43, which are equipped with the adsorption support plate 421, closer to or further apart from each other, the distance between the vacuum suction cup 422 and the corresponding two pressing knives 432 in the first direction can be adjusted. By moving the other two pressing components 43 closer to or further apart from each other, the corresponding two pressing knives 432 in the second direction, which is perpendicular to the first direction, can be adjusted. By adjusting the position of the vacuum suction cup 422 along the adsorption support plate 421, the vacuum suction cup 422 can be adjusted in the second direction. In this way, the distance between the pressing knives 432 and the distance between the vacuum suction cups 422 can be freely adjusted, which can adapt to products of different specifications within a certain range.

[0040] Specifically, the driving structure upon which the pressing edge components 43 move closer or further apart is not limited. For example, in this embodiment, the fixed parts of the relatively arranged lifting drive components 431 are respectively connected to two nuts of the same bidirectional lead screw pair to achieve synchronous approach or departure.

[0041] More specifically, the driving method of the bidirectional lead screw pair is not limited. For example... Figure 3 and Figure 4 The image shows a manually driven type, where the screw is turned by a knob to complete the drive. Figure 5 and Figure 6 The image shows an electrically driven type, where the motor and synchronous belt work together to rotate the lead screw to complete the drive.

[0042] It should be noted that the aforementioned solution for adjusting the spacing of the edge pressing component 43 and the vacuum suction cup 422 can only adapt to products of different specifications within a certain range. However, when the product size varies significantly, this solution may not meet the requirements. In this case, it is necessary to use the aforementioned quick-change disc to replace it with another compatible pickup module 4 using a one-click quick change.

[0043] As an improvement to the adsorption assembly 42, the adsorption assembly 42 also includes an auxiliary adsorption head 423. The auxiliary adsorption head 423 is installed below the center of the mounting plate 41, and the adsorption surface of the auxiliary adsorption head 423 is flush with the adsorption surface of the vacuum suction cup 422. The auxiliary adsorption head 423 is used to adsorb the center of large-sized products to ensure adsorption stability. Example

[0044] Reference Figure 7 The present invention provides a four-station pickup device, including a fixed frame 100, a sliding beam 200 and a sliding head 300.

[0045] The mounting bracket 100 is used to provide hardware support for other components.

[0046] Specifically, the structure of the fixing bracket 100 is not limited. For example... Figure 7 As shown, the fixing frame 100 in this embodiment includes four columns 110, two fixing beams 120 extending in the X direction, and two connecting beams extending in the Y direction.

[0047] The sliding beam 200 has two beams, both of which extend along the Y direction. Both ends of each sliding beam 200 are slidably connected to the fixed frame 100, and each sliding beam 200 is driven to slide independently along the X direction.

[0048] Specifically, the driving structure upon which the sliding beam 200 depends for sliding is not limited. For example... Figure 7 As shown, a rotary motor is installed at the end of the sliding beam 200 in this embodiment. A gear is sleeved on the output shaft of the rotary motor. A rack is arranged on the fixed beam 120 along its length direction. The gear meshes with the rack. When the output shaft of the rotary motor rotates, it will drive the gear to rotate, thereby causing the gear to move along the rack, and thus realizing the movement of the sliding beam 200 in the X direction.

[0049] The sliding head 300 is provided in two pairs and is respectively installed on two sliding beams 200. Each sliding head 300 is driven to slide along the corresponding sliding beam 200. Each sliding head 300 is equipped with a Z-axis driving pair. The output part of each Z-axis driving pair is equipped with the display panel segment picking head described in Embodiment 1, and the mounting bracket 1 is connected to the output part of the corresponding Z-axis driving pair.

[0050] Specifically, the driving structure upon which the slider 300 relies for sliding is not limited. For example... Figure 7 As shown, a rotary motor is installed on the sliding head 300 in this embodiment. A gear is sleeved on the output shaft of the rotary motor. A rack is arranged on the sliding beam 200 along its length direction. The gear meshes with the rack. When the output shaft of the rotary motor rotates, it will drive the gear to rotate, thereby causing the gear to move along the rack, and thus realizing the movement of the sliding head 300 in the Y direction.

[0051] Specifically, the type of Z-axis drive pair is not limited; linear motors, motor screw pairs, cylinders, etc., can all be used.

[0052] In addition, this embodiment also has a alignment vision camera installed on one sliding head 300 of each sliding beam 200. The alignment vision camera is used to visually position the segmented panel to calculate the material deviation of the segmented panel, thereby controlling the precise positioning and picking operation of the four sets of picking heads.

[0053] The working principle of the four-station pickup device in this embodiment is as follows: The X-axis position of the pickup head is adjusted by moving the sliding beam 200 along the X-axis; the Y-axis position of the pickup head is adjusted by moving the sliding head 300 along the Y-axis; and the pickup head is raised and lowered by the Z-axis drive auxiliary action to complete the pickup action.

[0054] It should be noted that when the pickup head adopts the quick-change disc and the spacing adjustment scheme of the edge pressing assembly 43 and vacuum suction cup 422 described in Embodiment 1, the pickup head can be adjusted and replaced according to the product type so that the pickup device can pick up products of different specifications at the same time. Example

[0055] Reference Figure 8 and Figure 9 This invention provides a picking method based on the aforementioned four-station picking device. If the four sliding heads 300 are defined as A1, A2, B1, and B2, and A1 and A2 are located on the same sliding beam 200, B1 and B2 are located on the same sliding beam 200, A1 and B1 are located on the same side in the Y direction, and A2 and B2 are located on the same side in the Y direction, then: For panel slabs that only have a single specification product: When the 200-degree spacing between the two sliding beams is met, the picking columns are equally distributed from X to the middle, and the sliding heads 300 on the two sliding beams 200 pick up synchronously; when the 200-degree spacing between the two sliding beams is not met, synchronous picking of A1 and A2 or synchronous picking of B1 and B2 is preferred. When the spacing between the two sliding heads 300 on the same sliding beam 200 is satisfied, the picking rows are equally distributed from Y to the middle, and the sliding heads 300 on the same sliding beam 200 are picked up synchronously; when the spacing between the two sliding heads 300 on the same sliding beam 200 is not satisfied, A1 and B1 are picked up synchronously or A2 and B2 are picked up synchronously. For panel panels with two or more product specifications: For the single product with the largest quantity, the panel picking method for single-specification products is adopted.

[0056] The following two specific examples will illustrate this in detail.

[0057] Example 1, such as Figure 8 As shown, this panel contains only a single product specification, arranged in five rows and seven columns. The picking head is shorter than the total length of two products in the same direction in both the X and Y directions, and performs three picking actions in total. The first time, perform six sets of cyclical exercises, that is... Figure 8 In steps 1-1 to 1-6, A1, A2, B1, and B2 all run synchronously in each cycle, picking up a total of 24 products; The second time, perform four sets of cyclical movements, that is... Figure 8In steps 2-1 to 2-4, A1 and B1 run synchronously in the first set of cyclic actions, A2 and B2 run synchronously in the second set of cyclic actions, A1 and B1 run synchronously in the third set of actions, and B2 runs alone in the fourth set of cyclic actions, picking up a total of 7 products. The third time, perform two sets of cyclical movements, that is... Figure 8 In steps 3-1 to 3-2, A1 and A2 run synchronously in the first set of cyclic actions, and B1 and B2 run synchronously in the second set of cyclic actions, picking up a total of 4 products.

[0058] Example 2, such as Figure 9 As shown, the panel contains three product specifications: Product 1, Product 2, and Product 3, arranged in five rows and nine columns. The picking head is shorter than the total length of two product pieces in the same direction in both the X and Y directions, and performs three picking actions in total. The first time, product 1 is picked up using B1 and B2, and fifteen sets of cyclic actions are performed. Figure 8 In steps 1-1 to 1-15, B1 and B2 operate synchronously in the cycle from 1-1 to 1-10, picking up a total of 20 pieces of product 1. In the cycle from 1-11 to 1-15, B1 and B2 pick up products 1 in separate rounds, picking up a total of 5 pieces of product 1. The second time, product 2 is picked up using A1, and ten sets of cyclic actions are performed, that is... Figure 8 In steps 2-1 to 2-10, each cycle is run independently by A1, picking up a total of 10 pieces of product 2. The third time, product 3 is picked up using A2, and ten sets of cyclic actions are performed, that is... Figure 8 In steps 3-1 to 3-10, each cycle is run independently by A2, picking up a total of 10 product pieces 3.
