Description

Technical Field

[0001] The present invention relates to the technical field of material identification, and in particular to a plastic material verification method and a plastic material verification system. Background Art

[0002] With the rapid development of the LED industry, demand for LED lamp beads has gradually increased, and as a result, the demand for the basic materials that make up LED package brackets has also gradually increased. Among them, the plastics that make up LED package brackets (mainly PPA105 plastic and PPA112 plastic) have no obvious differences in appearance, and standard testing cannot determine the type of plastic. However, the price difference between different types of plastic is large, which makes it possible for manufacturers to use low-priced plastic to pass off as high-priced plastic, achieving the effect of passing off inferior plastic as high-quality.

[0003] In the existing technology, the color difference of the LED package bracket before and after baking is mainly compared by visual observation to determine whether the plastic material is qualified. However, since there is no obvious color change between PPA105 plastic and PPA112 plastic before and after baking, it is impossible to accurately distinguish the plastic materials.

[0004] Therefore, in order to prevent suppliers from cutting corners and replacing materials, it is necessary to have a way to distinguish materials and strictly control quality. Summary of the Invention

[0011] As an improvement to the above solution, when the plastic bracket to be tested is baked, the baking time is 2.5 to 3.5 hours and the baking temperature is 170 to 190°C.

[0026] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0027] See also Figure 1 , Figure 1 A flow chart of a first embodiment of the plastic material verification method of the present invention is shown, which includes:

[0028] S101, baking the plastic bracket to be tested;

[0029] Generally, the plastic bracket to be tested can be placed in an oven for baking. The baking time is 2.5 to 3.5 hours and the baking temperature is 170 to 190°C.

[0030] In this embodiment, the baking time is preferably 3 hours and the baking temperature is preferably 180° C., but this is not a limitation and can be adjusted according to actual conditions.

[0031] S102, removing the lamp beads from the plastic bracket to be tested after the baking process;

[0032] Buckle off the lamp beads in the baked plastic bracket to separate the plastic bracket from the lamp beads.

[0033] S103, performing a strength test on the plastic bracket to be tested after the lamp beads are removed to obtain strength information, and determining a predicted strength type of the plastic component based on the strength information;

[0034] It should be noted that the strength of PPA112 plastic is higher than that of PPA105 plastic. Therefore, a reference strength range can be set and ensured to be between the strength of PPA112 plastic and the strength of PPA105 plastic.

[0035] During prediction, the plastic bracket to be tested whose strength information is greater than the benchmark strength range can be judged as "PPA112 plastic", the plastic bracket to be tested whose strength information is less than the benchmark strength range can be judged as "PPA105 plastic", and the plastic bracket to be tested whose strength information is within the benchmark strength range can be judged as "unknown plastic".

[0036] For example, a plastic bracket to be tested with strength information of 2.45 may be determined as "PPA112 plastic," and a plastic bracket to be tested with strength information of 2.19 may be determined as "PPA105 plastic."

[0037] Accordingly, when performing a strength test on the plastic bracket to be tested after the lamp beads are removed, the plastic bracket to be tested can be fixed by a jig, and the plastic bracket to be tested can be sent to a strength testing machine for strength testing by the jig.

[0038] like Figure 2 As shown, the fixture includes a fixture body, on which at least one lamp bead slot, at least one bracket slot and at least one isolation slot are provided. The lamp bead slot and the bracket slot are connected to each other through the isolation slot.

[0039] During operation, the lamp beads removed in step S102 can be placed in the lamp bead slot, and the plastic bracket to be tested can be placed in the bracket slot, thereby achieving effective fixation and support of the lamp beads and the plastic bracket to be tested, facilitating strength testing of the plastic bracket to be tested.

[0040] S104, re-encapsulating the lamp beads onto the plastic bracket to be tested after the strength test;

[0041] After the strength test is completed, the lamp beads and the plastic bracket to be tested can be subjected to die bonding, wire bonding, glue dispensing and baking to re-encapsulate the lamp beads to the plastic bracket to be tested after the strength test. The specific steps include:

[0042] (1) Fix the chip of the lamp bead to the bottom of the bowl of the plastic bracket to be tested through the die-bonding adhesive;

[0043] Die bonding: Use die bonding equipment to fix the chip to the bottom of the bowl of the plastic bracket to be tested with die bonding glue.

[0044] (2) Connect the positive and negative electrodes of the chip to the positive and negative electrodes of the plastic bracket to be tested through alloy wires to ensure that the lamp beads are normally conductive;

[0045] Wire welding: Use alloy wire to connect the positive and negative poles of the chip and the positive and negative poles of the plastic bracket to be tested through wire welding equipment to make the lamp bead conduct normally.

[0046] (3) Pour fluorescent glue into the bowl to perform glue dispensing;

[0047] Glue dispensing: Use a glue dispenser to pour the mixture of phosphor and glue into the bowl of the plastic bracket to be tested, which has already been die-bonded and wire-bonded.

[0048] (4) Bake the plastic bracket to be tested after the glue treatment.

[0049] S105, removing the encapsulated lamp beads from the plastic bracket to be tested again;

[0050] S106, performing a light parameter test on the lamp beads to obtain brightness information, and determining the brightness prediction type of the plastic component based on the brightness information;

[0051] After the finished product is packaged, the lamp beads are removed from the plastic bracket to be tested and the optical parameters are tested using an integrating sphere.

[0052] It should be noted that the brightness of the lamp beads in PPA112 plastic is lower than that in PPA105 plastic. Therefore, a reference brightness range can be set and ensured to be between the brightness of the lamp beads in PPA112 plastic and the brightness of the lamp beads in PPA105 plastic.

[0053] During prediction, the plastic bracket to be tested corresponding to the lamp beads whose brightness information is greater than the reference brightness range can be judged as "PPA105 plastic", the plastic bracket to be tested corresponding to the lamp beads whose brightness information is less than the reference brightness range can be judged as "PPA112 plastic", and the plastic bracket to be tested corresponding to the lamp beads whose brightness information is in the reference brightness range can be judged as "unknown plastic".

[0054] S107 , comprehensively analyzing the intensity prediction type and the brightness prediction type to determine the target type of the plastic component.

[0055] The target type of the plastic component can be determined by combining the intensity prediction type determined in step S103 and the brightness prediction type determined in step S107 .

[0056] For example, if the intensity prediction type determined in step S103 is “PPA105 plastic” and the brightness prediction type determined in step S107 is “PPA105 plastic”, then the target type can be determined to be “PPA105 plastic”;

[0057] For another example, if the intensity prediction type determined in step S103 is “PPA105 plastic” and the brightness prediction type determined in step S107 is “unknown plastic”, the target type may be determined to be “PPA105 plastic”.

[0058] Therefore, this embodiment can accurately determine the type of the plastic component by performing a strength test on the plastic bracket to be tested and performing a light parameter test on the lamp beads.

[0059] See also Figure 3 , Figure 3 A flow chart of a second embodiment of the plastic material verification method of the present invention is shown, which includes:

[0060] S201, baking the plastic bracket to be tested;

[0061] S202, performing a whiteness test on the plastic component in the plastic bracket to be tested after baking to obtain whiteness information, and determining a predicted whiteness type of the plastic component based on the whiteness information;

[0062] and Figure 1 The difference from the first embodiment shown is that this embodiment introduces a whiteness test to conduct a comprehensive test on the plastic bracket to be tested from multiple dimensions to further improve the accuracy of the test.

[0063] Generally speaking, there is no obvious color change between PPA105 and PPA112 plastics before and after baking. In comparison, the color change of PPA112 plastic is slightly larger. Therefore, further accurate testing can be performed using a whiteness test instrument.

[0064] Specifically, the plastic component in the plastic bracket to be tested can be placed in the test position of the whiteness test instrument, and the angle is adjusted to start the test. The whiteness test instrument displays the whiteness parameters of different plastics through light reflection.

[0065] It should be noted that the whiteness of PPA112 plastic is lower than that of PPA105 plastic. Therefore, a reference whiteness range can be set and ensured to be between the whiteness of PPA112 plastic and the whiteness of PPA105 plastic.

[0066] During prediction, the plastic bracket to be tested whose whiteness information is greater than the reference whiteness range can be judged as "PPA105 plastic", the plastic bracket to be tested whose whiteness information is less than the reference whiteness range can be judged as "PPA112 plastic", and the plastic bracket to be tested whose whiteness information is in the reference whiteness range can be judged as "unknown plastic".

[0067] For example, a plastic bracket to be tested with whiteness information of 99.93 may be determined as "PPA112 plastic," and a plastic bracket to be tested with whiteness information of 100.47 may be determined as "PPA105 plastic."

[0068] S203, removing the lamp beads from the plastic bracket to be tested after the baking process;

[0069] S204, performing a strength test on the plastic bracket to be tested after the lamp beads are removed to obtain strength information, and determining the predicted strength type of the plastic component based on the strength information;

[0070] S205, re-encapsulating the lamp beads onto the plastic bracket to be tested after the strength test;

[0073] S208 , comprehensively analyzing the whiteness prediction type, the intensity prediction type, and the brightness prediction type to determine a target type of the plastic component.

[0074] Therefore, this embodiment introduces a whiteness test to conduct a comprehensive test on the plastic bracket to be tested from multiple dimensions to further improve the accuracy of the test.

[0075] See also Figure 4 , Figure 4 A flow chart of a third embodiment of the plastic material verification method of the present invention is shown, which includes:

[0076] S301, collecting outer surface information of the plastic bracket to be tested, and determining the predicted appearance type of the plastic component based on the outer surface information;

[0077] and Figure 1 The difference from the first embodiment shown is that this embodiment introduces external surface information to perform a comprehensive test on the plastic bracket to be tested from multiple dimensions to further improve the accuracy of the test.

[0078] Generally speaking, the outer surface of PPA112 plastic is brushed, while the outer surface of PPA105 plastic is relatively smooth. Therefore, by introducing the outer surface information, the type of plastic part can be further determined.

[0079] S302, baking the plastic bracket to be tested;

[0080] S303, removing the lamp beads from the plastic bracket to be tested after the baking process;

[0081] S304, performing a strength test on the plastic bracket to be tested after the lamp beads are removed to obtain strength information, and determining the predicted strength type of the plastic component based on the strength information;

[0082] S305, re-encapsulating the lamp beads onto the plastic bracket to be tested after the strength test;

[0083] S306, removing the encapsulated lamp beads from the plastic bracket to be tested again;

[0084] S307, performing a light parameter test on the lamp beads to obtain brightness information, and determining the brightness prediction type of the plastic component based on the brightness information;

[0085] S308 , determining a target type of the plastic part by comprehensively considering the appearance prediction type, the strength prediction type, and the brightness prediction type.

[0086] Therefore, this embodiment introduces external surface information to perform a comprehensive test on the plastic bracket to be tested from multiple dimensions to further improve the accuracy of the test.

[0087] See also Figure 5 , Figure 5 A flowchart of a fourth embodiment of the plastic material verification method of the present invention is shown, which includes:

[0088] S401, collecting outer surface information of the plastic bracket to be tested, and determining the predicted appearance type of the plastic component based on the outer surface information;

[0089] S402, baking the plastic bracket to be tested;

[0090] S403, performing a whiteness test on the plastic component in the plastic bracket to be tested after the baking process to obtain whiteness information, and determining the predicted whiteness type of the plastic component based on the whiteness information;

[0094] S407, removing the encapsulated lamp beads from the plastic bracket to be tested again;

[0095] S408, performing a light parameter test on the lamp beads to obtain brightness information, and determining the brightness prediction type of the plastic component based on the brightness information;

[0096] S409 , comprehensively analyzing the appearance prediction type, whiteness prediction type, intensity prediction type, and brightness prediction type to determine a target type of the plastic component.

[0097] and Figure 1 The difference from the first embodiment shown is that this embodiment combines outer surface detection, whiteness test, intensity test and optical parameter test to conduct a comprehensive test on the plastic bracket to be tested from multiple dimensions to further improve the accuracy of the test.

[0098] For example, if the appearance prediction type is "unknown plastic", the whiteness prediction type is "PPA105 plastic", the strength prediction type is "PPA105 plastic", and the brightness prediction type is "PPA105 plastic", then the target type can be determined to be "PPA105 plastic".

[0099] Therefore, the plastic material verification method of the present invention can distinguish PPA105 plastic from PPA112 plastic based on the plastic's appearance, whiteness, strength, brightness and other properties, greatly improving the accuracy of plastic material verification. It can effectively prevent suppliers from cutting corners and substituting inferior materials, and strictly control quality.

[0100] See also Figure 6 , Figure 6 The specific structure of the plastic material verification system 100 based on the plastic material verification method of the present invention is shown, which includes an oven 1, a separation device 2, a strength testing machine 3, a die bonding device 4, a wire bonding device 5, a dispensing machine 6, an integrating sphere 7 and a prediction device 8. Specifically:

[0109] During operation, the plastic bracket to be tested is first placed in the oven 1 for baking treatment, and then the lamp beads in the plastic bracket to be tested are removed by the separation equipment 2, and the strength of the plastic bracket to be tested after the lamp beads are removed is tested by the strength testing machine 3 to obtain strength information, and then the prediction equipment 8 determines the strength prediction type of the plastic component based on the strength information; then, the chip of the lamp bead is fixed to the bottom of the bowl of the plastic bracket to be tested through the solid crystal base glue by the solid crystal equipment 4, and the positive and negative poles of the chip are connected to the positive and negative poles of the plastic bracket to be tested with alloy wire by the wire welding equipment 5, and fluorescent glue is poured into the bowl by the glue dispenser 6 for glue dispensing treatment, and then the plastic bracket to be tested after glue dispensing treatment is placed in the oven 1 for baking treatment, thereby completing the packaging of the lamp beads; then, the lamp beads in the plastic bracket to be tested are removed again by the separation equipment 2, and the light parameter test of the lamp beads is performed on the integrating sphere 7 to obtain brightness information, and then the prediction equipment 8 determines the brightness prediction type of the plastic component based on the brightness information; finally, the prediction equipment 8 comprehensively considers the strength prediction type and the brightness prediction type to determine the target type of the plastic component.

[0114] Therefore, by adding whiteness testing instruments and / or appearance inspection instruments, the plastic bracket to be tested can be comprehensively tested from multiple dimensions to further improve the accuracy of the test.

[0115] More preferably, the plastic material verification system 100 further includes a fixture 9 for fixing the plastic bracket to be tested.
