Description

Technical Field

[0001] This invention relates to the field of glass-based circuit board manufacturing technology, and in particular to a fully automatic vacuum plugging machine for glass substrates. Background Technology

[0002] Glass-based circuit boards (usually referring to circuit boards made with glass as the substrate, glass substrate) differ fundamentally from traditional circuit boards (usually referring to printed circuit boards, PCBs) in terms of materials, processes, and performance. These differences determine their applicability in different application scenarios.

[0003] Currently, an existing patent (publication number: CN120224569B) discloses a fully automatic integrated vacuum plugging machine. Although this vacuum plugging machine is suitable for fully automatic operation of loading, positioning, plugging and unloading of traditional PCB boards, it is not suitable for fully automatic operation of loading, positioning, plugging and unloading of glass substrates. The vacuum plugging machine uses a clamping method to transport PCB boards and realize loading and unloading. If the glass substrate is loaded, positioned, plugged and unloaded while in a clamped state, it is easy to cause the glass substrate to break. Therefore, the vacuum plugging machine is not suitable for fully automatic operation of loading, positioning, plugging and unloading of glass substrates.

[0004] Therefore, there is an urgent need to propose a fully automatic vacuum hole plugging machine for glass substrates that can automatically perform the feeding, positioning, hole plugging, and unloading operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a fully automatic vacuum plugging machine for glass substrates, which can avoid the automatic operation of feeding, positioning, plugging, and unloading of glass substrates while they are being clamped, thereby solving the technical problem that existing vacuum plugging machines cannot be applied to the automatic operation of feeding, positioning, plugging, and unloading of glass substrates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fully automatic vacuum plugging machine for glass substrates, comprising:

[0008] The rack extends horizontally, and the direction of the rack's extension is defined as the first direction.

[0009] The working chamber includes a feeding chamber, a plugging chamber, and a discharging chamber. The feeding chamber, plugging chamber, and discharging chamber are arranged sequentially on the frame along a first direction, and the feeding chamber, plugging chamber, and discharging chamber are connected to each other.

[0010] The support component is mounted on the frame and located inside the work chamber. The support component includes a worktable, an adjustment structure, a clamping assembly, and a support base. The adjustment structure is mounted on the support base and connected to the worktable. The clamping assembly is mounted on the support base and extends vertically through the worktable to clamp the glass substrate placed on the worktable.

[0011] A drive unit is mounted on the frame and located inside the working chamber. The drive unit is connected to the support seat and is used to drive the support component to reciprocate in the feeding chamber, the plugging chamber and the discharging chamber along the first direction.

[0012] The first vacuum suction cup handling mechanism is mounted on the frame and is used to vacuum suction and grasp the glass substrate to be plugged and move the glass substrate it grasps to place on the worktable.

[0013] An identification unit, located on the frame and above the loading bin, is used to identify the center position of the glass substrate on the first vacuum suction cup conveying mechanism and directly above the worktable. The adjustment structure adjusts the center of the worktable to align with the center of the glass substrate according to the identification result of the identification unit.

[0014] A hole-plugging device, located within a hole-plugging chamber, includes a base, a mounting base, a first lifting mechanism, a screen, a screen printing component, and a quantitative paste-dispensing mechanism. The first lifting mechanism is fixed within the hole-plugging chamber and drives the base to lift. The mounting base is mounted on the base, and the screen is detachably connected to the mounting base. The screen matches the glass substrate to be plugged. The quantitative paste-dispensing mechanism is mounted on the mounting base and applies conductive paste to the screen. The screen printing component is connected to the mounting base and applies conductive paste from the screen through the mesh openings of the screen into the holes of the conductive paste to be plugged on the glass substrate.

[0015] The second vacuum suction cup handling mechanism, located on the frame, is used to vacuum suction and pick up the glass substrate on the worktable of the carrier component that has been moved to the discharge bin.

[0016] Furthermore, the quantitative slurry feeding mechanism includes a first linear module, a connecting seat, a pneumatic telescopic unit, and a slurry cylinder; the first linear module is mounted on the mounting base and drivenly connected to the connecting seat, and is used to drive the connecting seat to move along a first direction; the slurry cylinder includes a cylinder and a piston, the slurry cylinder is slidably mounted on the connecting seat along the first direction, the piston is fixed on the connecting seat and is slidably sealed to the slurry cylinder, and the slurry cylinder can move relative to the piston along the first direction; the pneumatic telescopic unit is mounted on the connecting seat and drivenly connected to the slurry cylinder, and is used to drive the slurry cylinder to move along the first direction, so that the conductive slurry in the slurry cylinder is squeezed out from the center of the piston and coated onto the screen.

[0017] Furthermore, the quantitative slurry feeding mechanism also includes a proportional regulating valve located on the mounting base, used to control the air pressure of the pneumatic telescopic unit, so as to control the amount of slurry fed onto the screen by the slurry cylinder per unit time.

[0018] Furthermore, the screen printing component includes a first driving mechanism and a screen printing assembly, the screen printing assembly being mounted on a mounting base; the first driving mechanism is mounted on a base and drivenly connected to the mounting base, used to drive the mounting base to slide in a direction perpendicular to the first direction, thereby causing the screen printing assembly to slide in a direction perpendicular to the first direction; the screen printing assembly includes a squeegee assembly and a second lifting mechanism, the second lifting mechanism being mounted on the mounting base and drivenly connected to the squeegee assembly, the second lifting mechanism being used to drive the squeegee assembly to rise and fall, so that the squeegee assembly can squeeze the screen and cause the conductive paste on the screen to be inserted into the hole on the glass substrate where the conductive paste is to be inserted.

[0019] Furthermore, the plugging device also includes a screen bottom cleaning mechanism for cleaning the screen bottom.

[0020] Furthermore, the screen bottom cleaning mechanism includes a second driving mechanism and a cleaning component. The second driving mechanism is driven to the cleaning component. Under the drive of the second driving mechanism, the cleaning component slides along a direction that is horizontal and perpendicular to the first direction and cleans the screen bottom.

[0021] Furthermore, the cleaning assembly includes a fixed base, cleaning paper, a driving component, an unwinding drum, a winding drum, and an adhesive strip. The fixed base is drivenly connected to the second driving mechanism. The unwinding drum and the winding drum are both rotatably mounted on the fixed base. The adhesive strip, the unwinding drum, and the winding drum are parallel to each other and all extend in a direction perpendicular to the first direction. The line connecting the adhesive strip, the unwinding drum, and the winding drum forms a triangular structure. One end of the cleaning paper is wound on the unwinding drum, and the other end is wound on the unwinding drum after passing over the adhesive strip. The cleaning paper can contact the bottom of the screen. The driving component is mounted on the fixed base and is used to drive the winding drum to wind up.

[0022] Furthermore, the cleaning assembly also includes a third drive mechanism and a spraying assembly. The third drive mechanism is mounted on the mounting base and drivenly connected to the spraying assembly. The third drive mechanism is used to drive the spraying assembly to slide along the extension direction of the unwinding drum. The spraying assembly is used to spray cleaning liquid onto the cleaning paper.

[0023] Further, the adjustment structure includes adjustment components A, B, C, and D. Adjustment components A, B, C, and D are located at the four corners of the bottom of the worktable in a counter-clockwise direction. Each adjustment component includes a drive source, a sliding block, and a linkage seat. The sliding block is slidably mounted on the support seat, and the linkage seat is slidably mounted on the sliding block and linked to it. The linkage seat is fixedly connected to the bottom surface of the worktable. The drive source is located on the support seat and is used to drive the sliding block to slide. The linkage seat is horizontally perpendicular to the sliding direction of the sliding block along the support seat. Specifically, the sliding direction of the sliding block in adjustment component A is the same as that in adjustment component C, and the sliding direction of the sliding block in adjustment component B is the same as that in adjustment component D. The sliding direction of the sliding block in adjustment component A is perpendicular to the sliding direction of the sliding block in adjustment component B in the horizontal direction.

[0024] Furthermore, the clamping assembly includes a lifting structure, a connecting member, and a clamping member. The lifting structure is mounted on a support base. A waist-shaped groove is provided on the worktable. The waist-shaped groove extends in a direction that is horizontal and perpendicular to the first direction. The connecting member is driven to connect with the lifting end of the lifting structure. The connecting member also extends through the waist-shaped groove beyond the worktable and is connected and fixed to the clamping member.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In use, the fully automatic vacuum plugging machine for glass substrates of the present invention drives a carrying component to move along a first direction into the loading bin via a drive unit. Then, a first vacuum suction cup transport mechanism vacuum-adheses and moves the glass substrate to be plugged to a position directly above the worktable of the carrying component. At this point, a recognition unit identifies the center position of the glass substrate, and the adjustment structure of the carrying component fine-tunes the alignment of the worktable's center with the center of the glass substrate based on the recognition result, thereby reducing the number of times the glass substrate is handled. The first vacuum suction cup transport mechanism then places the glass substrate on the worktable, followed by a pressing assembly that presses the glass substrate onto the worktable. Finally, the drive unit... The drive unit moves the supporting component from the loading bin to the hole-plugging bin along the first direction. At this time, the first lifting mechanism of the hole-plugging device drives the base to descend, so as to drive the screen to a suitable position away from the glass substrate pressed on the worktable. Then, the conductive paste is applied to the screen by the quantitative paste-adding mechanism. Then, the conductive paste on the screen is filled into the holes of the glass substrate to be plugged by the screen through the mesh of the screen by the screen printing component, thus realizing the hole-plugging operation of the glass substrate. After the hole-plugging operation is completed, the drive unit drives the supporting component to move from the hole-plugging bin to the discharge bin. Finally, the second vacuum suction cup conveying mechanism vacuum suctions and picks up the glass substrate on the worktable in the discharge bin. In summary, the fully automatic vacuum hole-plugging machine for glass substrates of the present invention can avoid the automatic operation of loading, positioning, hole plugging and unloading of glass substrates while they are clamped, thereby solving the technical defects of existing vacuum hole-plugging machines that cannot be applied to the automatic operation of loading, positioning, hole plugging and unloading of glass substrates.

Detailed Implementation

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0050] In the description of this invention, it should be understood that the terms "width", "upper", "lower", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] Please refer to Figure 1-20 The present invention provides a fully automatic vacuum plugging machine for glass substrates, including a frame 1, a working chamber 2, a supporting component 3, a drive unit 4, a vacuum unit 5, a first vacuum suction cup transport mechanism 6, an identification unit, a plugging device 8, a second vacuum suction cup transport mechanism 9, and an electrical control box 91.

[0053] Reference Figure 1 and Figure 2 The frame 1 extends horizontally, and the direction of extension of the frame 1 is defined as the first direction, and the direction that is horizontally perpendicular to the first direction is defined as the second direction.

[0054] Reference Figure 1 and Figure 2 The working chamber 2 includes a feeding chamber 20, a plugging chamber 21, and a discharging chamber 22. The feeding chamber 20, plugging chamber 21, and discharging chamber 22 are sequentially arranged on the frame 1 along the first direction and are interconnected. The top doors of the feeding chamber 20, plugging chamber 21, and discharging chamber 22 can be closed and sealed. When the doors A201 of the feeding chamber 20, B210 of the plugging chamber 21, and C220 of the discharging chamber 22 are closed and sealed, the vacuum unit 5 draws a vacuum from the feeding chamber 20, plugging chamber 21, and discharging chamber 22, allowing the glass substrate to be plugged to undergo the plugging operation in a vacuum environment.

[0055] It should be noted that the opening and closing sealing of the doors of the feeding hopper 20, the plugging hopper 21, and the discharging hopper 22 are existing technologies and will not be described further here. Additionally, the vacuum unit 5 is also existing technology and will not be discussed further here.

[0056] Reference Figure 1 , Figure 3 and Figures 10-13 The supporting component 3 is mounted on the frame 1 and located inside the working chamber 2. The supporting component 3 includes a supporting base 30, a worktable 31, an adjustment structure 32, and a clamping assembly. The supporting base 30 is slidably disposed inside the working chamber 2 along a first direction. Specifically, two first guide rails 23 are fixed on opposite sides inside the working chamber 2, and the two first guide rails 23 are spaced apart along a second direction. The two sides of the supporting base 30 are slidably connected to the two first guide rails 23 by sliders.

[0057] Reference Figure 3 and Figures 10-13 An adjustment structure 32 is mounted on a support base 30 and connected to a worktable 31. The adjustment structure 32 is controlled by an electrical control box 91 fixed on a frame 1. The adjustment structure 32 is used to adjust the alignment of the center of the worktable 31 with the center of the glass substrate. Specifically, the adjustment structure 32 includes adjustment components A320, B321, C322, and D323. Adjustment components A320, B321, C322, and D323 are located at the four corners of the bottom of the worktable 31 in a counterclockwise direction. Each adjustment component includes a drive source 324, a sliding block 325, and a linkage seat 326. In this embodiment, the drive source 324 is a motor screw drive structure. In other embodiments, the drive source 324 can also be a cylinder or an electric push rod.

[0058] The sliding block 325 is slidably mounted on the support seat 30, and the linkage seat 326 is slidably mounted on the sliding block 325 and linked with the sliding block 325. The linkage seat 326 is connected and fixed to the bottom surface of the worktable 31. The drive source 324 is mounted on the support seat 30 and is used to drive the sliding block 325 to slide. The linkage seat 326 is horizontally perpendicular to the sliding direction of the sliding block 325 along the sliding direction of the sliding block 325 along the support seat 30.

[0059] Among them, the sliding direction of the sliding block 325 of the adjusting component A320 along the bearing seat 30 is the same as the sliding direction of the sliding block 325 of the adjusting component C322 along the bearing seat 30, the sliding direction of the sliding block 325 of the adjusting component B321 along the bearing seat 30 is the same as the sliding direction of the sliding block 325 of the adjusting component D323 along the bearing seat 30, and the sliding direction of the sliding block 325 of the adjusting component A320 along the bearing seat 30 and the sliding direction of the sliding block 325 of the adjusting component B321 along the bearing seat 30 are perpendicular to each other in the horizontal direction.

[0060] The adjustment process of adjustment structure 32 is described here: When the worktable 31 needs to be adjusted to move in the first direction, adjustment components D323 and B321 are activated. The drive source 324 of adjustment components D323 and B321 drives their respective sliding blocks 325 to move left or right, thereby driving their respective linkage seats 326 to drive the bearing seat 30 to move left or right. When the worktable 31 needs to be adjusted to move in the second direction, adjustment components A320 and C322 are activated. The drive source 324 of adjustment components A320 and C322 drives their respective sliding blocks 325 to move forward or backward, thereby driving their respective linkage seats 326 to drive the bearing seat 30 to move forward or backward. The worktable 31 can move forward or backward. When it is necessary to adjust the worktable 31 to move circumferentially, the adjusting components A320, B321, C322 and D323 act simultaneously. The drive source 324 of adjusting component A320 drives the sliding block 325 of adjusting component A320 to move forward, the drive source 324 of adjusting component B321 drives the sliding block 325 of adjusting component B321 to move to the right, the drive source 324 of adjusting component C322 drives the sliding block 325 of adjusting component C322 to move backward, and the drive source 324 of adjusting component D323 drives the sliding block 325 of adjusting component D323 to move to the left, thereby driving the worktable 31 to achieve circumferential adjustment.

[0061] A clamping assembly is mounted on the support 30 and extends vertically through the worktable 31, used to clamp the glass substrate placed on the worktable 31. (Refer to...) Figures 10-13 The clamping assembly includes a lifting structure 33, a driving assembly, a connecting member 331, and a clamping member 334. In this embodiment, the lifting structure 33 is a lifting cylinder. The lifting structure 33 is mounted on the support 30. A waist-shaped groove 310 is provided on the worktable 31. The waist-shaped groove 310 extends along the second direction. The connecting member 331 is driven to the lifting end of the lifting structure 33. The connecting member 331 passes through the waist-shaped groove 310 and extends out of the worktable 31 to be connected and fixed to the clamping member 334. The driving assembly is mounted on the support 30 and is used to drive the lifting structure 33 to move along the second direction, so that the connecting member 331 can move within the waist-shaped groove 310. With the clamping member 334 not clamping the glass substrate, the connecting member 331 is located at the front end within the waist-shaped groove 310, and the lifting end of the lifting structure 33 is extended. After the glass substrate is placed on the worktable 31, the driving assembly drives the lifting structure 33 to move backward along the second direction, causing the connecting member 331 to move from the front end to the rear end within the waist-shaped groove 310. At this time, the lifting structure 33 drives the connecting member 331 to lower the clamping member 334, thus clamping the glass substrate placed on the worktable 31. In this embodiment, two sets of clamping assemblies are provided, and the two sets of clamping assemblies are spaced apart along the second direction, which makes the clamping member 334 clamp the glass substrate more stably.

[0062] The driving component in this embodiment includes a third driving motor 330 and a lead screw transmission mechanism 332. The third driving motor 330 drives the lead screw transmission mechanism 332 to drive the clamping member 334 to move along the second direction. In other embodiments, the driving component may also be the first linear module 60, which is not limited here.

[0063] Reference Figure 3 There can be two support components 3, with one support component 3 located above the other support component 3, and the two support components 3 can move relative to each other along the first direction. That is, each support component 3 is equipped with an independent drive unit 4, which can improve the efficiency of the glass substrate plugging operation.

[0064] It should be noted that the clamping component 334 can be a flexible component to prevent the glass substrate from breaking when the clamping component 334 is clamping the glass substrate.

[0065] The drive unit 4 is mounted on the frame 1 and located in the working chamber 2. The drive unit 4 is controlled by the electrical control box 91 and is connected to the support seat 30. It is used to drive the support component 3 to reciprocate in the feeding chamber 20, the plugging chamber 21 and the discharging chamber 22 along the first direction.

[0066] Reference Figure 8 and Figure 9 The drive unit 4 includes a first drive motor 40, a belt 41, a drive pulley 42, and a driven pulley 43. Both the drive pulley 42 and the driven pulley 43 are rotatably mounted within the working chamber 2. The output shaft of the first drive motor 40 is driven by the drive pulley 42. Both ends of the belt 41 are connected to the drive pulley 42 and the driven pulley 43 respectively. The top surface of the belt 41 is fixedly connected to the support seat 30. Thus, by driving the belt 41 through the first drive motor 40, the support seat 30 can be moved along a first direction, thereby enabling the supporting component 3 to reciprocate along the first direction within the working chamber 2.

[0067] Reference Figure 3 The first vacuum suction cup transport mechanism 6 is mounted on the frame 1 and is controlled by the electrical control box 91. It is used to vacuum-adsorb and grasp the glass substrate to be plugged and move the grasped glass substrate onto the worktable 31. For the full automation of the pre-process and plugging process, refer to... Figure 1A center positioning device 92 is provided at the right end of the frame 1. Of course, the center positioning device 92 is controlled by the electrical control box 91. The center axis of the center positioning device 92 along the first direction, the first vacuum suction cup conveying mechanism 6, and the worktable 31 are collinear along the center axis of the first direction. The feed port of the center positioning device 92 is connected to the glass substrate production line. The glass substrate that has been center-positioned by the center positioning device 92 flows into the production line. The first vacuum suction cup conveying mechanism 6 enters the center positioning device 92 from the discharge port of the center positioning device 92 and vacuum suction-grabs the glass substrate to be plugged. At the same time, the first vacuum suction cup conveying mechanism 6 moves the glass substrate it has grabbed to the top of the loading bin.

[0068] Of course, when the first vacuum suction cup transport mechanism 6 loads the glass substrate into the loading chamber 20, the chamber door A201 of the loading chamber is in the open state; after the first vacuum suction cup transport mechanism 6 places the glass substrate on the worktable 31 located in the loading chamber, the chamber door A201 of the loading chamber is closed and sealed, and at the same time, the vacuum unit 5 draws a vacuum from the working chamber 2, so that the glass substrate to be plugged can be plugged in a vacuum environment.

[0069] Reference Figure 4 , Figure 5 The center positioning device 92 includes a base 920, a roller conveyor line 9201, a left limiting component 921, a right limiting component 922, a front limiting component 923, a rear limiting component 924, a fourth driving mechanism 927, and a fifth driving mechanism. The fourth driving mechanism 927, the fifth driving mechanism, the roller conveyor line 9201, the left limiting component 921, the right limiting component 922, the front limiting component, and the rear limiting component are all mounted on the base 920. The fourth driving mechanism 927 is used to drive the left limiting component 921 and the right limiting component 922 to move towards or away from each other along a first direction. The fifth driving mechanism is used to drive the front limiting component 923 and the rear limiting component 924 to move towards or away from each other along a second direction. The left limit assembly 921 and the right limit assembly 922 have the same structure; the front limit assembly and the rear limit assembly have the same structure; the structure of the left limit assembly 921 will be described in detail here: the left limit assembly 921 includes a movable seat 9212, a left limit sensor 9210 and a left limit member 9211. The left limit member 9211 and the left limit sensor 9210 are both fixed on the movable seat 9212, and the left limit sensor 9210 is controlled by the electrical control box 91. The movable seat 9212 is slidably disposed on the base 920 along the first direction; the fourth drive mechanism 927 and the fifth drive mechanism have the same structure.

[0070] Reference Figure 5The fourth drive mechanism 927 includes a second drive motor 9273, a first pulley 9270, a second pulley 9271, and a transmission belt 9272. The first pulley 9270 and the second pulley 9271 are rotatably mounted on the base 920. The second drive motor is fixed on the base 920 and driven by the first pulley 9270. The transmission belt 9272 is driven by the first pulley 9270 and the second pulley 9271 respectively. One side of the transmission belt 9272 is connected and fixed to the movable seat 9212 of the left limiting component 921; the other side of the transmission belt 9272 is connected and fixed to the movable seat 9212 of the right limiting component 922. Thus, under the drive of the second drive motor, the transmission belt 9272 can drive the left limiting component 921 and the right limiting component 922 to move towards or away from each other in the first direction.

[0071] Reference Figure 5 The roller conveyor 9201 has a first conveying direction. The roller conveyor 9201 is used to receive and convey the glass substrate to be plugged from the production line. When the left limit sensor 9210 detects that the glass substrate is in place, the left limit sensor 9210 feeds the signal back to the electronic control system. The electronic control system controls the fourth drive mechanism 927 to drive the moving seats 9212 of the left limit component 921 and the right limit component 922 to move towards each other in the first direction, so as to realize the positioning of the left and right sides of the glass substrate.

[0072] Furthermore, a rolling lifting assembly is also provided on the base 920 of the center positioning device 92. The rolling lifting assembly includes a roller support assembly 925 and a first lifting unit (not shown). The roller conveying direction of the roller support assembly 925 is the second direction, that is, the axis of rotation of the roller of the roller support assembly 925 is perpendicular to the axis of rotation of the roller of the roller conveyor line 9201. The first lifting unit is used to drive the lifting and lowering of the roller support assembly 925. After the left and right sides of the glass substrate are limited, the roller conveyor line 9201 stops moving, and the first lifting unit drives the roller support assembly 925 to rise, lifting the glass substrate. Then, the fifth driving mechanism drives the front limiting assembly and the rear limiting assembly to move towards each other along the second direction, realizing the front and rear position positioning of the glass substrate. In summary, the center positioning of the glass substrate on the center positioning device 92 can be achieved. The fifth driving mechanism can have the same structure as the fourth driving mechanism.

[0073] Of course, the structures of the front limit component and the rear limit component can be the same as those of the left limit component 921.

[0074] It should be noted that when the roller conveyor line 9201 is stopped, the roller support assembly 925 is driven to rise and lift the glass substrate by the first lifting unit mainly to avoid the glass substrate from contacting the rollers of the roller conveyor line 9201, thereby avoiding the glass substrate from breaking due to the friction between the glass substrate and the roller conveyor line 9201.

[0075] Reference Figure 14 The first vacuum suction cup transport mechanism 6 includes a first linear module 60, a second lifting unit 61, a connecting plate 62, a drive transmission mechanism 63, a connecting bar 64, two sets of first suction cup assemblies 65, and two sets of second suction cup assemblies 66. The first linear module 60 is mounted on the frame 1 and is drivenly connected to the second lifting unit 61. The first linear module 60 is used to drive the second lifting unit 61 to reciprocate along a first direction. The lifting end of the second lifting unit 61 is connected and fixed to the connecting plate 62. The connecting plate 62 extends along a second direction. The two sets of first suction cup assemblies 65 are slidably mounted on the connecting plate 62 along the second direction. The drive transmission mechanism 63 is mounted on the connecting plate 62 and is used to drive the two sets of first suction cup assemblies 65 to move towards or away from each other. The connecting bar 64 is fixed on the connecting plate 62. The two sets of second suction cup assemblies 66 are slidably mounted on the connecting bar 64 through sliding seats so that the two sets of second suction cup assemblies 66 can move towards or away from each other along the first direction. Therefore, it can be seen that the first vacuum suction cup handling mechanism 6 in this embodiment can adapt to the vacuum adsorption and gripping of glass substrates of different sizes.

[0076] It should be noted that the structure of the drive transmission mechanism 63 in this embodiment can be selected from the structure of the drive component described above, which will not be described in detail here.

[0077] In this embodiment, the second suction cup assembly 66 is adjusted manually to slide along the connecting strip 64.

[0078] Reference Figure 7 and Figure 15 The identification unit is mounted on the frame 1 and located above the loading bin, and is used to drive the identification unit to move along the second direction. The identification unit includes a drive module 71 and four CCD cameras 70. The CCD cameras 70 slide along the frame in the second direction and are distributed in an array, each of which is electrically connected to the electrical control box 91. The drive module 71 is mounted on the frame 1 and has four units. Each drive module 71 is used to drive each CCD camera 70 to move along the second direction.

[0079] Reference Figure 3At the position of the loading bin 20, when the first vacuum suction cup transport mechanism 6 moves the glass substrate directly above the worktable 31, the CCD camera 70 identifies the center position of the glass substrate on the first vacuum suction cup transport mechanism 6 (the glass substrate has four reference points, which are evenly distributed in an array around the center point of the glass substrate. By identifying the four reference points on the glass substrate by the four CCD cameras 70 respectively, the center position of the glass substrate can be determined), and uses the identified center position of the glass substrate as the first identification basis; the adjustment structure 32 adjusts the center of the worktable 31 to align with the center of the glass substrate according to the first identification basis of the identification unit.

[0080] Reference Figure 3 and Figures 16-20 The plugging device 8 is located inside the plugging chamber 21. The plugging device 8 includes a base 80, a mounting base 81, a first lifting mechanism 82, a screen printing plate 83, a screen printing component, and a quantitative paste feeding mechanism. The first lifting mechanism 82 is fixed inside the plugging chamber 21 and is used to drive the base 80 to rise and fall. In this embodiment, there are two bases 80, which are spaced apart along a first direction. There are four first lifting mechanisms 82. The lifting ends of two first lifting mechanisms 82 are respectively connected and fixed to the two ends of one base 80, and the lifting ends of the other two first lifting mechanisms 82 are respectively connected and fixed to the two ends of another base 80.

[0081] The mounting base 81 is slidably mounted on the two bases 80 along the second direction on opposite sides. The screen plate 83 is detachably connected to the mounting base via multiple lifting components 830. That is, multiple lifting components 830 are provided, each fixed on the mounting base, and the lifting end of the lifting component 830 is detachably connected to the screen plate 83. The lifting components 830 are used to drive the screen plate 83 to move up and down. Of course, the screen plate 83 matches the glass substrate to be plugged; specifically, it can be understood that the opposite sides of the screen plate 83 are detachably connected to the two bases. In this embodiment, the first lifting mechanism 82 is a lifting cylinder; in other embodiments, the first lifting mechanism 82 can also be an electric push rod.

[0082] Reference Figure 3 and Figures 16-20A quantitative paste application mechanism is located on the mounting base 81 and is used to apply conductive paste (silver paste or copper paste) onto the screen 83. Specifically, the quantitative slurry feeding mechanism includes a second linear module 850, a proportional regulating valve 851, a connecting seat 852, a pneumatic telescopic unit 853, and a slurry cylinder 854. The second linear module 850 is mounted on the mounting base and drivenly connected to the connecting seat 852. The second linear module 850 is used to drive the connecting seat 852 to move along a first direction. The slurry cylinder 854 includes a cylinder and a piston 855. The slurry cylinder 854 is slidably mounted on the connecting seat 852 along the first direction. The piston 855 is fixed on the connecting seat 852 and is slidably and sealed to the slurry cylinder 854. The slurry cylinder 854 can move relative to the piston 855 along the first direction. The pneumatic telescopic unit 853 is mounted on the connecting seat 852 and drivenly connected to the slurry cylinder 854. The pneumatic telescopic unit 853 is used to drive the slurry cylinder 854 to move along the first direction, so that the conductive slurry in the slurry cylinder 854 is squeezed out from the center of the piston 855 and coated onto the screen 83 along the first direction. In addition, the proportional regulating valve 851 is fixed on the mounting base and controlled by the electrical control box 91. The air pressure on the mounting base is used to control the pneumatic telescopic unit 853 to control the amount of slurry added to the screen 83 by the slurry cylinder 854 per unit time, so as to achieve the purpose of quantitative slurry addition.

[0083] Reference Figure 3 and Figures 16-20 The screen printing component is connected to the mounting base 81. The screen printing component is used to fill the conductive paste coated on the screen 83 into the holes on the glass substrate that need to be filled with conductive paste through the mesh openings of the screen 83. Specifically, the screen printing component includes a first driving mechanism 840 and a screen printing assembly. The screen printing assembly is mounted on the mounting base, and the first driving mechanism 840 is mounted on the base and drivenly connected to the mounting base 81. The first driving mechanism 840 is used to drive the mounting base to slide in a second direction, thereby causing the screen printing assembly to slide in the second direction, so that the screen printing assembly fills the conductive paste coated on the screen 83 into the holes on the glass substrate that need to be filled with conductive paste in the second direction. The screen printing assembly includes a squeegee assembly 841 and a second lifting mechanism 842. The second lifting mechanism 842 is mounted on the mounting base and drivenly connected to the squeegee assembly 841. The second lifting mechanism 842 is used to drive the squeegee assembly 841 to move up and down, so that the squeegee assembly 841 can squeeze the screen 83, thereby filling the conductive paste on the screen 83 into the holes on the glass substrate that need to be filled with conductive paste. Therefore, during the screen printing process, the squeegee assembly 841 slides along the second direction and the squeegee assembly 841 descends to squeeze the screen 83, thereby causing the conductive paste coated on the screen 83 to fill the holes of the conductive paste to be filled on the glass substrate through the mesh of the screen 83.

[0084] The structure of the first drive mechanism 840 can be the same as that of the drive unit 4, and will not be described in detail here.

[0085] Of course, the plugging chamber 21 is equipped with a position sensor controlled by the electrical control box 91. The position sensor is used to detect whether the screen printing component has completed the screen printing action.

[0086] In addition, the plugging device 8 also includes a screen bottom cleaning mechanism for cleaning the screen bottom of the screen 83.

[0087] Reference Figures 16-20 The screen bottom cleaning mechanism includes a second drive mechanism 860 and a cleaning component. The second drive mechanism 860 is mounted on the mounting base and is driven by the cleaning component. Under the drive of the second drive mechanism 860, the cleaning component slides along the second direction and cleans the bottom of the screen 83. The structure of the second drive mechanism 860 can be the same as that of the drive unit 4, and will not be described in detail here.

[0088] Reference Figures 16-20 The cleaning assembly includes a fixed base 861, cleaning paper 868, a drive unit 862, an unwinding drum 863, a take-up drum 864, and an adhesive strip 865. The fixed base 861 is drivenly connected to the second drive mechanism 860. The unwinding drum 863 and the take-up drum 864 are rotatably mounted on the fixed base 861. The adhesive strip 865, the unwinding drum 863, and the take-up drum 864 are parallel to each other and all extend along the second direction. The line connecting the adhesive strip 865, the unwinding drum 863, and the take-up drum 864 forms a triangular structure. One end of the cleaning paper 868 is wound on the unwinding drum 863, and the other end is wound on the unwinding drum 863 after passing over the adhesive strip 865. Since the screen 83 can be raised and lowered, the cleaning paper 868 can contact the bottom of the screen 83. The drive unit 862 is mounted on the fixed base 861 and is a motor used to drive the take-up drum 864 to wind up. After the glass substrate hole-filling operation is completed, the bottom surface of the screen 83 is adjusted to contact the cleaning paper 868. The second drive mechanism 860 drives the fixed base 861 to move along the second direction, causing the cleaning paper 868, drive component 862, unwinding drum 863, rewinding drum 864, and adhesive strip 865 to move synchronously along the second direction. This allows the cleaning paper 868 to wipe away the paste on the bottom surface of the screen 83, achieving the purpose of cleaning the screen bottom. Therefore, this invention can automatically wipe away residual silver or copper paste on the bottom surface of the screen, improving printing yield. Compared to manually cleaning the hole-filling chamber 21 after vacuum breaking, it reduces the vacuum breaking time of the hole-filling chamber 21.

[0089] In addition, refer to Figures 16-20The cleaning assembly also includes a third drive mechanism 866 and a spraying assembly 867. The third drive mechanism 866 is mounted on the mounting base and is drivenly connected to the spraying assembly 867. The third drive mechanism 866 is used to drive the spraying assembly 867 to slide along the extension direction of the unwinding drum 863. The spraying assembly 867 is used to spray cleaning liquid onto the cleaning paper 868. Specifically, before the cleaning paper 868 wipes off the bottom surface paste of the screen 83, the valve on the spraying assembly 867 is opened by the control box 91, and at the same time, the third drive mechanism 866 drives the spraying assembly 867 to move along a first direction, so that the cleaning liquid is sprayed onto the cleaning paper 868 along the first direction, increasing the area of ​​the cleaning liquid sprayed on the cleaning paper 868 and improving the cleaning effect.

[0090] The third drive mechanism 866 in this embodiment can be selected from the structure of the drive unit 4 described above; in other embodiments, the third drive mechanism 866 can also be a linear module, an electric push rod, or a rodless cylinder.

[0091] Reference Figure 3 The second vacuum suction cup transport mechanism 9 is mounted on the frame 1 and is used to vacuum-adhere and pick up the glass substrate from the worktable 31 of the carrier component 3, which has been moved into the discharge chamber 22. It should be noted that the second vacuum suction cup transport mechanism 9 has the same structure as the first vacuum suction cup transport mechanism 6, and will not be described in detail here. After the glass substrate has been plugged in the plugging chamber 21, the worktable 31 moves into the discharge chamber 22. At this time, the door C220 of the discharge chamber 22 opens, and the second vacuum suction cup transport mechanism 9 removes the glass substrate from the worktable 31 in the discharge chamber 22 and places it on the table surface 93 located at the left end of the frame 1.

[0092] Working principle of the invention:

[0093] Before officially starting the hole-filling operation on the glass substrate, a trial print of the paste drop points on the first glass substrate is required (i.e., the squeegee assembly 841 descends and squeezes the screen 83, causing the conductive paste coated on the screen 83 to fill the holes of the conductive paste to be filled on the first glass substrate pressed on the worktable 31 through the mesh of the screen 83). After the trial print of the paste drop points on the glass substrate is completed, the drive unit 4 drives the worktable 31 back to the loading bin 20, so that the recognition unit can identify the position of the paste drop points on the glass substrate by the screen 83, and thus determine the center position of the screen 83. After the recognition unit recognizes, learns and stores the position of the paste drop points, the drive unit 4 drives the worktable 31 to move to the unloading bin 22, so that the first glass substrate can be taken out by the second vacuum suction cup transport mechanism 9. The identification unit identifies the position of the slurry drop point of the screen printing plate 83 on the glass substrate as the second identification basis. When the glass substrate hole plugging operation officially begins (starting from the second glass substrate hole plugging operation), the drive unit 4 drives the worktable 31 to move into the loading bin. The bin door A201 opens. At this time, the first vacuum suction cup transport mechanism 6 picks up the glass substrate positioned at the center position on the center positioning device 92 and moves it above the loading bin. The four CCD cameras 70 identify the four reference points on the glass substrate respectively to determine the center position of the glass substrate. At this time, in the loading bin, the adjustment structure 32 adjusts the center of the worktable 31 to align with the center of the glass substrate based on the center position of the glass substrate. Then, the first vacuum suction cup transport mechanism 6 places the glass substrate on the worktable 31 and presses the glass substrate on the worktable 31 with the pressing component.

[0094] After the center of the glass substrate is aligned with the center of the worktable 31 and the glass substrate is pressed onto the worktable 31, the worktable 31 is moved from the loading bin to the plugging bin 21 by the drive unit 4. At the same time, the center of the worktable 31 is adjusted to align with the center of the screen 83 based on the position of the paste drop point on the glass substrate (second reference) by the adjustment structure 32, so that the conductive paste on the screen 83 can be plugged into the holes of the conductive paste to be plugged in the glass substrate through the mesh of the screen 83. Next, the conductive paste is applied to the screen 83 in the first direction by the metering paste dispensing mechanism, and then the doctor blade assembly 841 slides in the second direction and descends to squeeze the screen 83, so that the conductive paste applied to the screen 83 is filled into the holes of the conductive paste to be plugged in the glass substrate through the mesh of the screen 83.

[0095] After the glass substrate has completed the hole plugging in the hole plugging chamber 21

[0096] After the center of the adjustment structure 32 adjusts the worktable 31 to be aligned with the center of the glass substrate, the drive unit 4 drives the worktable 31 to move from the plugging chamber 21 to the discharge chamber 22. At this time, the chamber door C220 of the discharge chamber 22 is opened, and the glass substrate located on the worktable 31 in the discharge chamber 22 is taken out and placed on the table surface 93 by the second vacuum suction cup transport mechanism 9.

[0097] In conclusion:

[0098] 1. The fully automatic vacuum plugging machine for glass substrates of the present invention can avoid automatic operations such as feeding, positioning, plugging, and unloading of glass substrates while they are being clamped, thereby solving the technical defects of existing vacuum plugging machines that cannot be applied to the automatic operations of feeding, positioning, plugging, and unloading of glass substrates.

[0099] 2. When the fully automatic vacuum plugging machine for glass substrates of the present invention is in use, the worktable 31 moves back and forth in the working chamber 2 along the first direction. That is, the glass substrate is vacuum adsorbed and transported only during loading and unloading, which reduces the number of times the glass substrate is transported and reduces the risk of glass breakage.

[0100] 3. Connect the fully automatic vacuum plugging machine for glass substrates to the production line to achieve full automation of the upstream and downstream processes, improve production efficiency, solve the problem of manual handling of large-size glass substrates, and avoid glass breakage or operator injury caused by human operation, thus reducing labor costs.

[0101] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
