Description

Technical Field

[0001] The present invention relates to the technical field of LED packaging equipment, and in particular to a full-automatic LED glue dispensing machine and a use method thereof. Background Art

[0002] In the production and packaging process of light-emitting diodes (LEDs), precisely weighed phosphors and encapsulation adhesives are required to encapsulate and cure the LEDs. The packaging process requires high accuracy of the phosphor formula. Slight differences in the weighing process will cause the product's color temperature, color rendering index, color tolerance, color coordinates and other parameters to fail to meet the specified standards, resulting in a decrease in product yield and even product scrapping.

[0003] The traditional method of packaging glue dispensing is to use electronic scales for manual glue dispensing operations. Phenomena such as under-dispensing, omissions, mis-dispensing, inaccurate weighing, and forgetting to record data often occur, resulting in poor controllability of the dispensing process. If errors occur in the dispensing process and the quality of subsequent products is unqualified, it will inevitably cause great losses.

[0004] With the continuous expansion of LED production capacity, the LED packaging industry has gradually used glue dispensing machines to replace manual glue dispensing. However, the existing glue dispensing machines are still based on semi-automatic operation and still require manual assistance. They often put the glue and phosphor into a large beaker first, and then pour them into the glue dispensing syringe after stirring and degassing for glue dispensing. This operation is inefficient and can only complete each order separately, and cannot carry out efficient glue dispensing for multiple orders at the same time.

[0005] In view of the fierce competition in the current LED industry, how to improve the efficiency of LED packaging operations and improve the accuracy of LED glue dispensing will become an important research direction to reduce the cost of LED products and improve the performance of LED products. Summary of the invention

[0006] The purpose of the present invention is to provide a fully automatic LED glue dispensing machine and a method of using the machine, which is reasonably designed and easy to use, in view of the defects and shortcomings of the prior art. The machine can automatically weigh glue and phosphor and can dispense glue for multiple orders at the same time.

[0007] In order to solve the problems existing in the background technology, the technical solution adopted by the present invention is: it includes a weighing device and a control device; the weighing device includes a plurality of horizontally placed annular powder placing plates, a manipulator swing arm arranged at the center of the annular area of ​​the powder placing plates, a plurality of electronic scale wheels arranged at the periphery of the annular area of ​​the powder placing plates, and a pressurizing device arranged above the electronic scale wheels; the control device includes a processor, a memory and an input device, an output device, and an identification device connected to each other; the processor is respectively connected to the weighing device, the identification device, the input device, and the output device.

[0008] Furthermore, the plurality of glue powder placement trays are placed in a ring shape for placing glue powder bottles, and 3 to 8 glue powder placement trays may be provided, and the glue powder placement trays may rotate around the manipulator swing arm.

[0009] Furthermore, the robot swing arm is composed of a connecting rod, a claw, and a rotating fulcrum. The two ends of the connecting rod are respectively connected to the claw and the rotating fulcrum. The rotating fulcrum is set at the center of the annular area of ​​the rubber powder placement plate. The connecting rod is a telescopic rod. The claw can be freely retracted at one end of the connecting rod. In the initial state, it hovers horizontally above the rubber powder placement plate.

[0010] Furthermore, the multiple electronic scale wheels are used to place glue syringes and are arranged on the periphery of the annular area formed by the multiple glue powder placement plates. They can also rotate around the manipulator arm. The load-bearing accuracy of the electronic scale wheels is ±0.0005g.

[0011] Furthermore, the pressurizing device is arranged above the electronic scale wheel. Its function is that when the robot arm grabs a certain glue powder bottle, it is inverted by the rotating fulcrum and extended to the bottom of the pressurizing device by the connecting rod, the pressurizing device applies a certain pressure to allow the glue or fluorescent powder in the glue powder bottle to leak out.

[0012] As an improvement, the top opening of the glue dispensing syringe is sealed with a plug, and an order number barcode or QR code is provided on the surface of the glue dispensing syringe.

[0013] As an improvement, the glue powder bottle uses a drip head made of soft material instead of a bottle cap, and a barcode or a QR code is provided on the surface of the glue powder bottle for marking the product information and weight of the glue or fluorescent powder.

[0014] Furthermore, the identification device includes a first scanner and a second scanner; the first scanner is used to scan the order number barcode or QR code on the surface of the glue dispensing syringe, and transmit the information to the processor of the control device; the second scanner is used to scan the barcode or QR code information on the surface of the glue powder bottle, and transmit the information to the processor of the control device.

[0015] Furthermore, the input device includes a keyboard and a mouse; the keyboard and the mouse are connected to the processor respectively.

[0016] Furthermore, the output device includes a printer, a speaker, and a display.

[0017] The present invention also discloses a method for using a fully automatic LED glue dispensing machine, which comprises the following steps: 1. calculating the required weight of fluorescent glue and the required glue and fluorescent powder ratio information according to the production order, and inputting the information into the memory of the control device;

[0018] 2. The processor of the control device drives the printer to print out the corresponding order number barcode or QR code and stick it on the surface of the dispensing syringe. Then, the dispensing syringe is placed in the wheel of the electronic scale, with the end with the plug facing downward and the dispensing syringe outlet facing upward.

[0019] 3. Place the glue bottles and fluorescent powder bottles required for the order in the glue and fluorescent powder placement trays respectively;

[0020] 4. In the initial state, the processor controls the count on the electronic scale wheel to be cleared;

[0021] 5. According to the order preset in the memory, the processor controls the first scanner to scan the order information on the dispensing syringe, and transmits the information to the processor for analysis;

[0022] 6. The processor analyzes the weight of fluorescent glue required for the order and the ratio of glue and fluorescent powder required to form the fluorescent glue component;

[0023] 7. The processor controls the second scanner to scan the barcode information of the glue powder bottle where the required glue or fluorescent powder is located;

[0024] 8. The processor controls the robot arm to clamp the corresponding glue powder bottle, and inverts the glue powder bottle by rotating the fulcrum and places it under the pressurizing device;

[0025] 9. The pressurizing device uses pneumatic control to leak a certain amount of glue or fluorescent powder from the glue powder bottle, and drips it to the glue outlet of the glue syringe for the order to be executed through the drip head;

[0026] 10. The electronic scale wheel weighs the weight of the glue or fluorescent powder dripped in. When the required weight is reached, the system stops pressurizing, and the robot swings its arm to drive the glue powder bottle to flip and reset;

[0027] 11. The processor performs the dripping of other glue and phosphor;

[0028] 12. When the glue dispensing syringe for the first order has finished dispensing glue, the system automatically scans the next order and performs the drip dispensing work;

[0029] 13. When the glue and fluorescent powder required for one or several orders are the same, you can drip the same type of glue or fluorescent powder without frequent switching. The electronic scale wheel can be automatically rotated to drip the glue or fluorescent powder into different orders as needed;

[0030] 14. When all orders are completed and the remaining glue powder bottles are collected, they can be replaced by printing the corresponding barcode or QR code through the printer according to the remaining glue or fluorescent powder in the glue powder bottles stored in the system.

[0031] The beneficial effects of the present invention are as follows: it can automatically control the dripping amount through the glue powder ratio preset by the system, completely avoiding the errors caused by manual glue addition, greatly improving the formula accuracy of the fluorescent glue, and pre-mounting barcode and other two-dimensional code information on the glue dispensing syringe, one order and one code. At the same time, the system uses a scanning glue powder bottle through a pressurized dripping method to accurately control the amount of glue or fluorescent powder used, and can monitor the weight of the remaining glue or fluorescent powder in real time for the next glue dispensing. The present invention solves the problem of poor formula accuracy caused by manual glue dispensing errors in the prior art, which leads to the photoelectric parameters of LED products failing to meet the requirements. The collaborative operation of multiple orders also improves the overall efficiency of LED glue dispensing, thereby improving the overall efficiency of LED production, while also reducing production costs.

[0043] Furthermore, the pressurizing device 15 is arranged above the electronic scale wheel 16. Its function is that when the robot arm 14 grabs a glue powder bottle 17, it is inverted through the rotating fulcrum 143 and extended to the bottom of the pressurizing device 15 by the connecting rod 141, the pressurizing device 15 applies a certain pressure to allow the glue or fluorescent powder 19 in the glue powder bottle 17 to leak out.

[0050] According to another aspect of the present invention, a method for using the fully automatic LED glue dispensing machine according to the present invention is also disclosed, which is described as follows in conjunction with a preferred embodiment:

[0051] For example: Order A involves fluorescent glue with the following components: glue a, glue b, phosphor R, phosphor Y, among which glue weight: phosphor weight = 9:1, glue a: glue b = 1:3, phosphor R: phosphor Y = 1:4.

[0052] Assuming that order A requires 50g of the above fluorescent glue, then after calculation, glue a=11.25g, glue b=33.75g, phosphor R=1g, and phosphor Y=4g.

[0053] Follow these steps:

[0054] 1. Input the proportion component information of all orders, such as order A / B / C / D / E / F, into the memory 22 of the control device 2, and the processor 21 calculates the required weight of fluorescent glue and the required amount of glue and fluorescent powder, such as the information shown in the above order A;

[0055] 2. For example, a printed barcode or QR code 182 of the corresponding order number of order A is attached to the surface of the glue dispensing syringe 18, and then the glue dispensing syringe 18 is placed in the electronic scale wheel 16, with the end with the sealing plug 181 facing downward and the glue outlet of the glue dispensing syringe 18 facing upward;

[0056] 3. Place the glue powder bottles 17 containing glue a, glue b, phosphor R, phosphor Y, etc. required for order A in the independent glue powder placement tray 13 respectively;

[0057] 4. In the initial state, the processor 21 controls the count on the electronic scale wheel 16 to be cleared;

[0058] 5. According to the preset order A in the memory 22, the processor 21 controls the first scanner 251 to scan the order information on the glue dispensing syringe 18, and transmits the information to the processor 21 for analysis;

[0059] 6. The processor 21 controls the second scanner 252 to scan the barcode information of the glue powder bottle 17 where the required glue a is located;

[0060] The processor 21 controls the robot arm 14 to clamp the glue powder bottle 17 where the glue a is located, and turns the glue powder bottle 17 upside down and places it under the pressurizing device 15 by rotating the fulcrum 143;

[0061] 8. The pressurizing device 15 pneumatically controls the glue powder bottle 17 to leak a certain amount of glue through the dripping head 171 and drips it into the glue outlet of the glue dispensing syringe 18 of order A;

[0062] 9. The electronic scale wheel 16 weighs the weight of the glue a dripped in. When the required weight of 11.25 g is reached, the system stops pressurizing, and the manipulator swing arm 14 drives the glue powder bottle 17 to flip and reset;

[0063] 10. The processor 21 performs dripping of glue b, phosphor R, and phosphor Y. The process is the same as dripping of glue a, and will not be repeated here.

[0064] 11. When the glue dispensing syringe 18 of order A has finished dispensing glue, the system automatically scans the next order B and executes the dripping glue dispensing work.

[0065] Another embodiment of the present invention is: when the types of glue and fluorescent powder required for one order or several orders are the same, the electronic scale wheel 16 can be automatically rotated to drip the glue or fluorescent powder 19 into different orders as needed without frequent switching when dripping the same type of glue or fluorescent powder.

[0066] When all orders are completed and the remaining glue powder bottles 17 are collected, the corresponding barcode or QR code 172 can be printed by the printer 242 for replacement according to the remaining glue or fluorescent powder 19 in the glue powder bottles 17 stored in the system.

[0067] This specific implementation method can automatically control the dripping amount through the glue powder ratio preset by the system, completely avoiding the error caused by manual glue addition, greatly improving the formula accuracy of the fluorescent glue, and pre-mounting barcode and other two-dimensional code information on the glue syringe, one order and one code. At the same time, the system uses a scanning glue powder bottle through a pressurized dripping method to accurately control the amount of glue or fluorescent powder used, and can monitor the weight of the remaining glue or fluorescent powder in real time for the next glue mixing. The present invention solves the problem of poor formula accuracy caused by manual glue mixing errors in the prior art, which leads to the photoelectric parameters of LED products not meeting the requirements. The collaborative operation of multiple orders also improves the overall efficiency of LED glue mixing, thereby improving the overall efficiency of LED production, while also reducing production costs.

[0068] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
