Abstract
Description
Technical field:
[0001] The present invention relates to the technical field of lamps, and in particular to a method for replacing a heat dissipation phase change inner shell of an integrated lamp and a production line thereof. Background technology:
[0002] As a new generation of lighting tools, LED lamps have the advantages of energy saving, high efficiency, and long life, and are widely used in the lighting industry. Although the light source of LED lamps is called a "cold light source", in fact, they still generate a lot of heat during the light-emitting process. Therefore, LED lamps require a heat sink to dissipate heat in time to avoid overheating and damage to the light source. The higher the power of the lamp, the more heat needs to be dissipated, and the larger and heavier the heat sink is generally required. In order to reduce the weight of the lamp and control the cost, some lamps are installed with efficient heat dissipation cores on the radiator, such as: composite heat dissipation phase change liner, which can reduce the volume and weight of the lamp radiator while meeting the heat dissipation requirements.
[0003] However, with the application, it was found that after long-term use, the phase change inner shell of some lamps with composite heat dissipation phase change inner shell failed, causing damage to the light source of the lamp and failure of the entire lamp. In terms of warranty maintenance, in theory, only the phase change inner shell and light source and other accessories need to be replaced. However, since the phase change inner shell and the lamp are generally installed by interference fit, after removing the phase change inner shell, the joint part of the lamp body has been deformed due to long-term use, and the joint surface has become rough, making it impossible to re-install the inner shell. Usually, the entire lamp can only be replaced, and the maintenance cost is very high. Summary of the invention:
[0004] The technical problem to be solved by the present invention is to provide a method for replacing an integrated lamp heat dissipation phase change liner and its production line. After the phase change liner fails, the method only requires replacing the phase change liner and light source and other accessories to complete the after-sales maintenance of the entire lamp, which can greatly reduce the maintenance cost of the lamp with a phase change liner after it fails.

[0045] The replacement method of the integrated lamp heat dissipation phase change liner is as follows:
[0046] Step 1: adjust the positions of the rear positioning blocks 133 and the quick clamps 134 on the first workpiece positioning tray 13 and the second workpiece positioning tray 23 on the base 131 according to the size of the lamp 3 and fix them; pull down the long cross bar 1434 of the first blocker 14 and clamp it with the elastic buckle 1412; place the first workpiece positioning tray 13 on the conveyor belt 122 of the first conveyor 12, with the front or rear side of the first workpiece positioning tray 13 against the inner side wall of the guide rail 121 of the first conveyor 12, and the left side of the first workpiece positioning tray 13 against the short cross bar 1435 of the first blocker 14; clamp the light source side of the lamp upward on the first workpiece positioning tray 13 On the top, adjust the position of the pressure working head 151 of the first press 15 so that it is aligned with the position of the primary phase change inner tank, and then remove the lamp; perform the same operation on the second blocker, the second workpiece positioning tray 23 and the second press 25; drill two injection holes 311 on the end face of the primary phase change inner tank of the lamp 3 to be maintained that is in contact with the light source and pour out the internal working fluid, simply apply sealant on the circle where the end cover 33 and the primary phase change inner tank are combined, and then take out the optical components and electronic components of the lamp 3; connect the infusion interface of one injection gun 4 to the tap water pipe, and connect the infusion interface of the other injection gun 4 to the drainage hose, and the other end of the drainage hose is connected to the drain outlet.
[0047] Step 2: Place the lamp 3 with the light source side facing upwards on a heating tray with an opening on one side, and place it together with the heating tray into the first tunnel furnace 11 to heat and keep warm to the primary temperature T1; then use a tool to tilt the heating tray to slide the lamp 3 into the first workpiece positioning tray 13, and use the manual quick clamp 134 to clamp and fix the lamp 3.
[0048] Step three, insert the two injection guns 4 into the two injection holes 311 of the primary phase change liner together, the outer periphery of the front end of the injection gun 4 and the inner wall of the injection hole 311 are interference fit, and the outer periphery of the front end of the injection gun 4 is made of heat-resistant rubber material; press the switch handles of the two injection guns 4 at the same time, use one injection gun 4 to inject coolant into the primary phase change liner, and use the other injection gun 4 to drain the excess coolant from the drain hose. After the set injection time t, release the switch handles of the two injection guns 4 and pull out the two injection guns 4.
[0049] Step 4: Control the first press 15 to press down the primary phase change liner within 5 seconds to separate it from the heat dissipation body 32 of the lamp, and a part of the primary phase change liner falls into the base 131 through the air avoidance hole 1312; open the elastic buckle 1412, and the interception component bounces upward under the action of the spring 1433; start the first conveyor 12 to send the lamp 3 to the next process, and then pull down the long cross bar 1434 and clamp it with the elastic buckle 1412; prepare to press out the primary phase change liner of the next lamp to be maintained.
[0050] Step 5. Within one minute, place the lamp with the primary phase change liner removed with the light source side facing down on a heating tray with an opening on one side, and transfer it to the second tunnel furnace 21 for heating and insulation to the secondary temperature T2; then use a tool to tilt the heating tray so that the lamp 3 slides into the second workpiece positioning tray 23, and the manual quick clamp 134 clamps the lamp 3 to fix it; use the second press 25 to press in the prepared secondary phase change liner; open the interception component of the second blocker, start the second conveyor 22 to send the lamp to the next process, and prepare to press in the secondary phase change liner for the next lamp to be maintained.
[0051] The above method can be used to continuously replace the phase change inner tanks of multiple lamps that need maintenance.
[0052] Assume that the bottom diameter of the heat dissipation cavity of the heat dissipation body 32 is D1; the bottom outer diameter of the primary phase change liner is D2, the external height is h, the wall thickness is a, the specific heat capacity is C1, and the density is ρ; the injection mass per unit time is b; the specific heat capacity of the coolant is C2; the bottom outer diameter of the secondary phase change liner is D3; the inclination angle of the inner wall of the heat dissipation cavity of the heat dissipation body 32, the inclination angle of the outer wall of the primary phase change liner and the inclination angle of the outer wall of the secondary phase change liner are equal, all are θ, 80≤θ<85; when θ is less than 80°, the hot and cold interference fit between the primary phase change liner and the heat dissipation body will fail, and when θ is greater than 85°, when the heat dissipation body is heated to press out the primary phase change liner, the inner wall of the heat dissipation cavity will be damaged. Both the primary phase change liner and the secondary phase change liner have a hot and cold interference fit with the heat dissipation cavity. According to the different sizes of the hot and cold interference fit between the primary phase change liner and the heat dissipation body, the difference between the bottom outer diameter D3 of the secondary phase change liner and the bottom diameter D1 of the heat dissipation cavity is 1.2 to 4 times the difference between the bottom outer diameter D2 of the primary phase change liner and the bottom diameter D1 of the heat dissipation cavity, and the thermal expansion coefficient of the primary phase change liner is less than or equal to the thermal expansion coefficient of the radiator body.
[0053] The primary temperature T1 and θ satisfy the following relationship, and 84≤T1<200(1);
[0054]
[0055] When the primary temperature T1 is greater than 100°C, the surface coating of the lamp will be damaged. Generally, the temperature resistance of the paint surface of a lamp will not exceed 100°C, and the coolant tap water may boil at a temperature exceeding 100°C, which will cause the algorithm of formula (1) to fail. If the lamp uses special surface treatment, T1 can be the maximum heat resistance temperature of the paint surface, but will not exceed 200°C. When it exceeds 200°C, the primary phase change liner will be pressed out and the inner wall of the heat dissipation cavity will be damaged.
[0056] The injection time t is determined according to formula (2);
[0057]
[0058] In formula (2), T c is the ambient temperature, k is the coefficient corrected according to the experiment, k=0.1.
[0059] Assume that the temperature of the heated lamp when pressing the secondary phase change inner tank is the secondary temperature T2, 80<T2<100. When T2 is greater than 100℃, the surface spraying of the lamp will be damaged. Generally, the temperature resistance of the paint surface of the lamp will not exceed 100℃. If the lamp adopts special surface treatment, T2 takes the maximum heat resistance temperature of the paint surface.
[0060] If the secondary phase change liner is to be made using the same mold as the primary phase change liner, the material of the secondary phase change liner should be made of aluminum alloy of the same series but different grades with similar properties such as thermal conductivity to the primary phase change liner but different thermal expansion coefficients, and the mold temperature, holding time and other parameters of the secondary phase change liner need to be reasonably adjusted.
[0061] The experiment was conducted using a heat dissipation body and a primary phase change liner made of ADC12 material. The liner was heated to different temperatures and pressed into the primary phase change liner. The lamp was then completely cooled and left for one day. The heat dissipation effect was tested after the light source was lit for 2 hours. See Table 1.
[0062] The heat dissipation body, the primary phase change liner and the secondary phase change liner are all made of ADC12 material for the experiment (only the material of the primary phase change liner of Examples 5, 6, 7 and 8 is 6063, and the thermal expansion coefficient of 6063 is greater than that of ADC12). The lamp is heated to different temperatures to cool the primary phase change liner, the primary phase change liner is pressed out, and the heat dissipation body is heated again and pressed into the secondary phase change liner. After the lamp is completely cooled and placed for one day, the heat dissipation effect is tested after the light source is lit for 2 hours. The experimental data and effects are shown in Table 2 (in Table 2, the external height of the primary phase change liner is h=0.045m, the wall thickness is a=0.005m, the specific heat capacity is C1=900J / (kg·℃), and the density is ρ=2670kg / m 3 ; The coolant is water, the mass of liquid injected per unit time is b = 0.3kg / s, the specific heat capacity of the coolant is C2 = 4186J / (kg·℃); the ambient temperature is T c=25°C, k=0.1).
