Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a precision dispensing device for LED display modules. Background Technology

[0002] In the manufacturing process of LED display modules, the dispensing process is a key step. Its main purpose is to achieve functions such as encapsulation, fixation or protection by applying glue to specific areas of the display module.

[0003] However, in traditional dispensing equipment, display modules are typically transported continuously via conveyor belts, with the dispensing mechanism performing the dispensing operation during transport. Due to the continuous movement of the conveyor belt, the display modules are susceptible to dragging or vibration during dispensing. Vibration can cause dispensing position deviation, reducing dispensing accuracy and affecting subsequent packaging quality, even leading to product defects. Secondly, dispensing equipment usually employs a one-by-one processing method, dispensing only a single display module at a time. This single-point operation mode is inefficient and cannot meet the demands of the modern display industry for large-scale, high-efficiency production. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a precision dispensing device for LED display modules to solve the problems of low dispensing efficiency and unstable dispensing.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a precision dispensing device for LED display modules, comprising:

[0006] Machine tool;

[0007] A conveying mechanism, located inside the machine, is used to convey display module to be glued, wherein the conveying mechanism includes multiple conveyor belts arranged side by side;

[0008] A dispensing mechanism is mounted on a machine base and includes multiple dispensing heads.

[0009] A lifting assembly, which is mounted on the machine platform;

[0010] A cantilever, located directly above the conveying mechanism and mounted on the lifting end of the lifting assembly;

[0011] A baffle, which is fixed to one side of the cantilever;

[0012] An opening is formed inside the baffle;

[0013] Multiple cylinder grippers are arranged in a linear array on one side of the cantilever. Each cylinder gripper includes two claws that move in opposite directions. The claws of each cylinder gripper penetrate the opening of the baffle.

[0014] A detection component for detecting display module is mounted on the gripper of a cylinder gripper and is electrically connected to the cylinder gripper.

[0015] The beneficial effects of this utility model are:

[0016] 1) The lifting module drives the cantilever and baffle to descend, stopping each display module on the conveyor belt. This ensures the display modules remain stationary during dispensing, avoiding displacement issues caused by conveyor belt dragging or vibration in traditional technologies. Furthermore, the baffle precisely positions multiple display modules in a straight line, providing a stable foundation for subsequent dispensing operations. Simultaneously, the detection component monitors the position of the display modules in real time. When the detection component identifies a display module, it generates an electrical signal to trigger the cylinder gripper to automatically clamp it. This clamping function further secures the display module, ensuring it does not move even slightly during dispensing, thus significantly improving dispensing accuracy and reducing product defect rates caused by dispensing deviation.

[0017] 2) Secondly, by working in conjunction with multiple dispensing heads and multiple conveyor belts, dispensing can be performed on multiple stationary display modules at once, thereby significantly improving dispensing efficiency and meeting the needs of large-scale automated production lines. In summary, by utilizing the combined design of baffles and cylinder grippers, the stopping, detection, and clamping processes of display modules are automated, further reducing the time and cost of manual intervention.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the dispensing mechanism includes a three-axis robotic arm, which is mounted on a machine platform, and a plurality of dispensing heads are arranged in a linear array on the Z-axis moving end of the three-axis robotic arm.

[0020] Furthermore, the lifting assembly includes two lifting cylinders, which are respectively fixed on both sides of the machine base.

[0021] Furthermore, the two ends of the cantilever are respectively fixed to the drive ends of two lifting cylinders.

[0022] Furthermore, the cross-section of the baffle is in the shape of an inverted "L".

[0023] Furthermore, each of the two grippers of the cylinder clamp has an installation groove inside.

[0024] Furthermore, the detection component includes a transmitting photoelectric sensor and a receiving photoelectric sensor, wherein the transmitting photoelectric sensor and the receiving photoelectric sensor are respectively fixed in the two gripper mounting slots of the cylinder gripper.

[0025] The beneficial effect of adopting the above-mentioned further solution is that by opening mounting slots inside the two grippers of the cylinder gripper and embedding the transmitting photoelectric sensor and the receiving photoelectric sensor into the mounting slots, the physical interference of the detection components on the gripper's clamping function is effectively avoided. The built-in design of the mounting slots ensures that the detection components do not protrude from the surface of the gripper, thereby ensuring that the gripper can maintain a flat contact surface and uniform clamping force when clamping the display module.

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] In the manufacturing process of display modules, the dispensing process is a key step. Its main purpose is to achieve functions such as encapsulation, fixation or protection by applying glue to specific areas of the display module.

[0033] However, in traditional dispensing equipment, display modules are typically transported continuously via conveyor belts, with the dispensing mechanism performing the dispensing operation during transport. Due to the continuous movement of the conveyor belt, the display modules are easily affected by dragging or vibration during dispensing. Vibration can cause dispensing position deviation, reducing dispensing accuracy and affecting subsequent packaging quality, even causing product defects. Secondly, dispensing equipment usually adopts a one-by-one processing method, that is, dispensing only one display module at a time. This single-point operation mode is inefficient and cannot meet the demands of the modern display industry for large-scale, high-efficiency production. To address these issues, the inventor has proposed a rolling machine for exhaust pipe production.

[0034] The present invention provides the following preferred embodiments.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the precision dispensing equipment for LED display modules includes:

[0036] 10 machines;

[0037] The conveying mechanism 20 is located inside the machine base 10 and is used to convey the display module to be glued. The conveying mechanism 20 includes multiple conveyor belts arranged side by side.

[0038] A dispensing mechanism 30 is mounted on the machine base 10 and includes multiple dispensing heads 302.

[0039] Lifting assembly 40 is mounted on machine base 10;

[0040] The cantilever 50 is located directly above the conveying mechanism 20 and is mounted on the lifting end of the lifting assembly 40.

[0041] Baffle 60 is fixed to one side of cantilever 50;

[0042] Opening 70 is located inside baffle 60;

[0043] Multiple cylinder grippers 80 are arranged in a linear array on one side of the cantilever 50. Each cylinder gripper 80 includes two claws 801 that move in opposite directions. The claws 801 of each cylinder gripper 80 penetrate the opening 70 of the baffle 60.

[0044] The detection component 90 is used to detect the display module. The detection component 90 is disposed on the gripper 801 of the cylinder gripper 80 and is electrically connected to the cylinder gripper 80.

[0045] The lifting module drives the cantilever 50 and baffle 60 to descend, stopping each display module on the conveyor belt. This ensures the display modules remain stationary during dispensing, avoiding displacement issues caused by conveyor belt dragging or vibration in traditional technologies. Furthermore, the baffle 60 precisely positions multiple display modules in a straight line, providing a stable foundation for subsequent dispensing operations. Simultaneously, the detection component 90 monitors the position of the display modules in real time. When the detection component 90 identifies a display module, it generates an electrical signal to trigger the cylinder gripper 80 to automatically clamp it. The clamping function of the cylinder gripper 80 further secures the display module, ensuring it does not move even slightly during dispensing. This significantly improves dispensing accuracy and reduces product defect rates caused by dispensing deviation.

[0046] Secondly, by having multiple dispensing heads 302 work in conjunction with multiple conveyor belts, dispensing can be performed on multiple stationary display modules at once, thereby significantly improving dispensing efficiency and meeting the needs of large-scale automated production lines. In summary, by utilizing the cooperative design of baffle 60 and cylinder gripper 80, the stopping, detection and clamping process of display modules is automated, further reducing the time and cost of manual intervention.

[0047] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the dispensing mechanism 30 includes a three-axis robotic arm 301, which is mounted on the machine base 10. Multiple dispensing heads 302 are arranged in a linear array on the Z-axis moving end of the three-axis robotic arm 301.

[0048] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the lifting assembly 40 includes two lifting cylinders, which are fixed on both sides of the machine base 10 respectively, and the two ends of the cantilever 50 are fixed on the drive ends of the two lifting cylinders respectively.

[0049] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the cross-section of the baffle 60 is in the shape of an inverted "L".

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the cylinder gripper 80 has mounting slots 802 inside both grippers 801. The detection component 90 includes a transmitting photoelectric sensor 901 and a receiving photoelectric sensor 902, wherein the transmitting photoelectric sensor 901 and the receiving photoelectric sensor 902 are respectively fixed in the mounting slots 802 of the two grippers 801 of the cylinder gripper 80.

[0051] By creating mounting slots 802 inside the two grippers 801 of the cylinder gripper 80 and embedding the transmitting photoelectric sensor 901 and the receiving photoelectric sensor 902 into the mounting slots 802, the physical interference of the detection component 90 on the gripper's clamping function is effectively avoided. The built-in design of the mounting slots 802 ensures that the detection component 90 does not protrude from the surface of the gripper 801, thereby ensuring that the gripper 801 can maintain a flat contact surface and uniform clamping force when clamping the display module.

[0052] The specific working process of this utility model is as follows:

[0053] (1) Stop display module

[0054] First, the lifting module drives the cantilever 50 and the baffle 60 to descend, so that the baffle 60 stops the display module on each conveyor belt, ensuring that the display module is stationary during the dispensing process, and accurately positioning multiple display modules in a straight line.

[0055] (2) Fixed display module

[0056] When the display module is moved to the position between the two grippers 801 of the cylinder gripper 80 and stopped by the baffle 60, the display module blocks the transmission of electrical signals between the HE12-JD252N model transmitting photoelectric sensor 901 and the HE12-JD252N model receiving photoelectric sensor 902. Therefore, the position of the display module can be sensed. At this time, the receiving photoelectric sensor 902 and the transmitting photoelectric sensor 901 send electrical signals to the cylinder gripper 80, and the grippers 801 of the cylinder gripper 80 clamp the display module.

[0057] (3) Apply adhesive

[0058] After the display module on each conveyor belt is clamped and fixed by the cylinder gripper 80, the three-axis robotic arm 301 drives multiple dispensing heads 302 to move above each display module on the conveyor belt, so that each dispensing head 302 corresponds to each display module, and then the dispensing process of the display module is completed by the dispensing head 302.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
