Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] This utility model embodiment provides a backlight module dispensing device for display assembly equipment, see reference. Figures 1 to 11 The backlight module dispensing device includes a frame platform 100 and a dispensing unit 1, a detection unit 2, a first transfer robot unit 3, and a second transfer robot unit 4 connected to the frame platform 100.

[0033] The two dispensing units 1 and the detection unit 2 are sequentially arranged on the frame platform 100 along a first direction (the length direction of the frame platform 100 in this embodiment) and extend along a second direction (the width direction of the frame platform 100 in this embodiment). The first transfer robot unit 3 is transversely mounted between the two dispensing units 1 and the detection unit 2 along the first direction. The second transfer robot unit 4 is mounted on the detection unit 2 and extends along the first direction to the outside of the frame platform 100. The dispensing unit 1 is configured to dispense adhesive to the backlight module. The detection unit 2 is configured to detect insufficient or broken adhesive in the adhesive layer obtained by dispensing. The first transfer robot unit 3 is configured to feed the backlight module into the dispensing unit 1 and transfer the backlight module from the dispensing unit 1 to the detection unit 2. The second transfer robot unit 4 is configured to send the backlight module from the detection unit 2 to the outside of the backlight module dispensing device.

[0034] The dispensing unit 1 includes a first transfer stage assembly 11, a dispensing assembly 12, and a first detection assembly 13. The first transfer stage assembly 11 extends along the second direction on the frame platform 100. The dispensing assembly 12 and the first detection assembly 13 are respectively mounted above the first transfer stage assembly 11. The first transfer stage assembly 11 carries the backlight module and transfers it within the dispensing unit 1. The dispensing assembly 12 dispenses adhesive onto the backlight module. The first detection assembly 13 detects the thickness of the adhesive layer obtained through dispensing.

[0035] Specifically, the first transfer robot unit 3 picks up the loaded backlight module and feeds it into the first transfer platform assembly 11. The first transfer platform assembly 11 first moves the backlight module below the dispensing assembly 12, where the dispensing assembly 12 dispenses adhesive onto the backlight module. After dispensing, the first transfer platform assembly 11 moves the backlight module below the first detection assembly 13, where the first detection assembly 13 detects the thickness of the adhesive layer obtained from dispensing. After the thickness detection is completed, the first transfer platform assembly 11 moves the backlight module below the first transfer robot unit 3, and the first transfer robot unit 3 then picks up and transfers the backlight module to the detection unit 2.

[0036] It should be noted that when one of the dispensing units 1 is dispensing glue to the backlight module, the first transfer robot unit 3 picks up another backlight module that is being loaded and sends it to another dispensing unit 1 to perform the dispensing operation simultaneously, thereby reducing the waiting time between the front-end and back-end processes and improving the dispensing efficiency.

[0037] In specific plans, such as Figure 4 As shown, the first transfer platform assembly 11 includes a first linear drive module 111 and a carrier platform 112. The first linear drive module 111 is connected to the rack platform 100 and extends along the second direction. The carrier platform 112 is used to load the backlight module and is movably connected to the first linear drive module 111.

[0038] In specific plans, such as Figure 5As shown, the dispensing assembly 12 includes a dual-actuator linear drive mechanism 121, a dispensing mechanism 122, and a cleaning mechanism 123. The dual-actuator linear drive mechanism 121 is mounted transversely above the first transfer platform assembly 11 and extends along the first direction. Two dispensing mechanisms 122 are movably connected to the dual-actuator linear drive mechanism 121, and a cleaning mechanism 123 is disposed below each dispensing mechanism 122. The dual-actuator linear drive mechanism 121 drives the dispensing mechanism 122 to move in the first direction. The dispensing mechanism 122 dispenses adhesive to the backlight module, and the cleaning mechanism 123 cleans the dispensing mechanism 122. In each dispensing unit 2, the dispensing assembly 12 includes two separately drivable dispensing mechanisms 122. The two dispensing mechanisms 122 can simultaneously dispense adhesive to the same backlight module, thereby improving dispensing efficiency, which is particularly suitable for larger backlight modules.

[0039] In specific plans, such as Figure 6 As shown, the dispensing mechanism 122 includes a second linear drive module 1221, a lifting drive module 1222, an injection module 1223, and a vision positioning module 1224. The second linear drive module 1221 is movably connected to the dual-actuator linear drive mechanism 121 and extends along the second direction. The lifting drive module 1222 is movably connected to the second linear drive module 1221. The injection module 1223 and the vision positioning module 1224 are respectively vertically and vertically connected to the lifting drive module 1222. The dual-actuator linear drive mechanism 121 can drive the dispensing mechanism 122 to move as a whole, thereby adjusting the position of the injection module 1223 in the first direction. The second linear drive module 1221 can drive the lifting drive module 1222 to move, thereby adjusting the position of the injection module 1223 in the second direction. The lifting drive module 1222 can drive the injection module 1223 to move vertically, thereby adjusting its position in the longitudinal direction. The dispensing module 1223 is equipped with a dispensing nozzle (not shown in the attached drawings) for dispensing adhesive to the backlight module. The visual positioning module 1224 acquires image information to locate the specific dispensing position, ensuring that the dispensing module 1223 can dispense adhesive at the accurate position.

[0040] In specific plans, such as Figure 7As shown, the cleaning mechanism 123 includes a feeding tray 1231, a receiving tray 1232, a strip of cleanroom wipes 1233, a cleaning boss 1234, and multiple guide rollers 1235. The strip of cleanroom wipes 1233, which is in the form of a roll, is released from the feeding tray 1231, and guided by the multiple guide rollers 1235, passes through the upper surface of the cleaning boss 1234 and is retrieved to the receiving tray 1232. After the dispensing mechanism 122 completes the dispensing operation, the dispensing nozzle of the dispensing module 1223 is brought to the cleaning boss 1234 from above by the belt-type cleanroom cloth 1233 through the drive control of the dual-actuator linear drive mechanism 121, the second linear drive module 1221 and the lifting drive module 1222. Then, the belt-type cleanroom cloth 1233 is driven to move by the feeding tray 1231 and the receiving tray 1232, and the belt-type cleanroom cloth 1233 removes the overflow glue and other debris around the dispensing nozzle, thus cleaning the dispensing nozzle.

[0041] In the specific design, the first detection component 13 is located between the dispensing component 12 and the first transfer robot unit 3. For example... Figure 8 As shown, the first detection component 13 includes a third linear drive module 131 and a thickness detection probe 132. The third linear drive module 131 is mounted horizontally above the first transfer stage assembly 11 and extends along the first direction. The thickness detection probe 132 is movably connected to the third linear drive module 131. When the backlight module after dispensing is moved below the first detection component 13, the thickness detection probe 132 detects the thickness of the adhesive layer obtained by dispensing.

[0042] The detection unit 2 includes a second transfer stage assembly 21 and a second detection assembly 22. The second transfer stage assembly 21 extends along the second direction on the frame platform 100, and the second detection assembly 22 is mounted above the second transfer stage assembly 21. The second transfer stage assembly 21 is used to carry the backlight module and transfer it inside the detection unit 2. The second detection assembly 22 is used to detect the adhesive layer obtained by dispensing to confirm whether there is insufficient adhesive or adhesive breakage.

[0043] Specifically, the second transfer platform assembly 21 first moves to below the first transfer robot unit 3 to receive the backlight module fed in from the first transfer robot unit 3. Then, it moves the backlight module to below the second detection assembly 22, where the second detection assembly 22 detects the adhesive layer obtained from dispensing to confirm whether there is insufficient or broken adhesive. After the detection is completed, the second transfer platform assembly 21 moves the backlight module to below the second transfer robot unit 4, where the second transfer robot unit 4 picks up the backlight module and transfers it to the outside of the backlight module dispensing device, for example, to the next work unit.

[0044] The second transfer stage assembly 21 has the same structure as the first transfer stage assembly 11 in the dispensing unit 1, so it will not be described in detail again.

[0045] In specific plans, such as Figure 9 As shown, the second detection component 22 includes a support frame 221, a CCD camera 222, and a surface light source 223. The support frame 221 is mounted above the second transfer stage assembly 21. The CCD camera 222 and the surface light source 223 are connected to the support frame 221. The surface light source 223 is located below the CCD camera 222 and has a through hole at a position corresponding to the CCD camera 222. When the second transfer stage assembly 21 moves the backlight module below the second detection component 22, the surface light source 223 is turned on. The CCD camera 222 detects the adhesive layer obtained by dispensing based on the acquired image information to confirm whether there is insufficient adhesive or adhesive breakage.

[0046] Among them, such as Figure 10 As shown, the first transfer robot unit 3 includes a fourth linear drive module 31 and a first gripping robot 32. The fourth linear drive module 31 is transversely mounted between the two dispensing units 1 and the detection unit 2 along the first direction. The first gripping robot 32 is movably connected to the fourth linear drive module 31. The first gripping robot 32 is configured to grip the backlight module and be driven to move by the fourth linear drive module 31, thereby enabling the backlight module to be fed into the dispensing unit 1 and transferred from the dispensing unit 1 to the detection unit 2.

[0047] Among them, such as Figure 11As shown, the second transfer robot unit 4 includes a fifth linear drive module 41 and a second gripping robot 42. The fifth linear drive module 41 is mounted on the detection unit 2 and extends along the first direction to the outside of the frame platform 100. The second gripping robot 42 is movably connected to the fifth linear drive module 41. The second gripping robot 42 is configured to grip the backlight module and be driven to move by the fifth linear drive module 41, thereby enabling the backlight module to be delivered from the detection unit 2 to the outside of the backlight module dispensing device.

[0048] In this embodiment, as Figures 1 to 3 As shown, the backlight module dispensing device also includes a defective product conveyor belt 5, which is disposed on the side of the detection unit 2 and below the second transfer robot unit 4. In this backlight module dispensing device, after the backlight module dispensing is completed, when the detection results of the first detection component 13 and the second detection component 22 are both qualified, the second transfer robot unit 4 moves the qualified backlight module along the second direction to the outside of the dispensing device and sends it to the next process, such as sending it to the assembly device; when the detection result of the first detection component 13 or the second detection component 22 is unqualified, the second transfer robot unit 4 transfers the unqualified backlight module to the defective product conveyor belt 5, and the defective product conveyor belt 5 sends the unqualified backlight module out of the dispensing device and to the next process, such as the rework process.

[0049] In summary, the backlight module dispensing device provided in the above embodiments of this utility model integrates two dispensing units and a detection unit into a single dispensing device. During the dispensing process of the backlight module, from dispensing the backlight module to detecting the adhesive layer, and finally sending the dispensed and inspected backlight module to the next process, all processes are automated, improving production efficiency. Furthermore, the rational layout of the functional units makes the connections between them more compact, resulting in a smaller device size and reduced footprint on the production floor. The inclusion of two dispensing units that can operate simultaneously reduces waiting time between upstream and downstream processes, further improving dispensing efficiency.

[0050] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
