Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of light source curing, and particularly relates to an infrared curing light source. BACKGROUND

[0002] With the continuous progress of industrial informatization, the efficiency requirement for silicon wafer and silicon chip welding is also continuously improved. The traditional infrared heating rod curing method is often used for heating and curing of soldering, but it has problems such as long time consumption, uneven heating effect, short service life of infrared rod, etc., resulting in increased production cost, and the production efficiency is reduced when the infrared rod is replaced, therefore, using the infrared curing light source for silicon wafer and silicon chip welding becomes a better choice.

[0003] The existing infrared curing light source is fixed on the wall, so that the infrared curing light source is located above the conveying belt. The infrared LED lamp on the PCB lamp plate emits light, so that the infrared light passes through the glass under the PCB lamp plate and irradiates the glass below, so that the silicon wafer and silicon chip that need to be welded on the conveying belt are irradiated by the infrared light when passing below the infrared curing light source. The molecules on the surface of the irradiated silicon wafer and silicon chip can absorb the energy of the infrared radiation, and convert the absorbed infrared radiation energy into heat energy, so that the temperature inside the silicon wafer and silicon chip rapidly rises, and then the silicon wafer and silicon chip are cured. At the same time, the water cooling and air cooling system in the infrared curing light source reduces the temperature of the PCB lamp plate.

[0004] The existing infrared curing light source also has some problems in use. The water cooling system on the existing infrared curing light source will cause the pipeline at the water injection port to age during long-term use, resulting in reduced elasticity of the pipeline at the water injection port. At the same time, during the water cooling process, the cold water output by the pipeline at the water injection port is in contact with the surrounding hot water, resulting in a change in the temperature of the pipeline material, thereby causing thermal expansion and cold contraction. Long-term use of this phenomenon will cause stress on the connection between the pipeline at the water injection port, resulting in loosening of the connection, and thus causing some water cooling liquid to be lost, reducing the cooling effect. The decline in cooling effect will cause the temperature of the PCB lamp plate to rise, and the performance and service life of the electronic components on the PCB lamp plate will be reduced under long-term high-temperature operation.

[0005] Therefore, the present application provides an infrared curing light source. SUMMARY

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1

[0035] like Figures 1 to 8As shown, an infrared curing light source according to an embodiment of the present invention includes a main body 1, two pieces of glass 11 are fixedly connected to the bottom of the main body 1, the two pieces of glass 11 are distributed up and down at the bottom of the main body 1, and a closed space is formed between the two pieces of glass 11, a cooling box 13 is provided in the middle of the main body 1, the cooling box 13 is fixedly connected to the inner wall of the main body 1, a PCB light board 12 is fixedly connected to the bottom end of the cooling box 13, the PCB light board 12 is located above the glass 11, a display circuit board 14 is fixedly connected to the top of the main body 1, an indicator light is provided on the display circuit board 14, a gas injection interface 15 is fixedly connected to one side of the main body 1, and a silencer is fixedly connected to the other side of the main body 1 Device 16, the air injection interface 15 and the silencer 16 are connected to the enclosed space between the two pieces of glass 11, and the top of the main body 1 near the air injection interface 15 is symmetrically fixedly connected with a water injection interface 17, and the water injection interface 17 is connected to the cooling box 13 below it. An early warning component is provided on one side of the water injection interface 17, and the early warning component is used to sound an alarm when there is water leakage at the water injection interface 17 and the water pipe interface. The top of the main body 1 near the silencer 16 is symmetrically fixedly connected with a drainage interface 18, and the drainage interface 18 is connected to the cooling box 13 below it. The surfaces of the water injection interface 17 and the drainage interface 18 are provided with a protective shell 19 fixedly connected to the top surface of the main body 1.

[0036] Specifically, there are still some problems in the use of existing infrared curing light sources. The water cooling system on the existing infrared curing light source will age during long-term use, resulting in reduced elasticity of the pipe at the water injection interface 17. At the same time, during the water cooling process, the cold water output from the pipe at the water injection interface 17 comes into contact with the surrounding hot water, causing the temperature of the pipe material to change, thereby causing thermal expansion and contraction. If this continues for a long time, stress will be generated on the pipe connection at the water injection interface 17, causing the pipe connection at the water injection interface 17 to loosen, and then causing part of the water-cooling liquid to be lost, thereby reducing the cooling effect. The reduction in cooling effect will cause the temperature of the PCB lamp board 12 to rise. Under long-term high-temperature operation, the performance and life of the electronic components on the PCB lamp board 12 will be reduced.

[0037] Therefore, the present invention solves this problem by setting up a corresponding structure, fixing one end of the main body 1 on the wall so that the main body 1 is located above the conveyor belt, and at this time, the air injection interface 15 and the water injection interface 17 are connected to the cold air pipe and the water injection pipe respectively, and the drainage interface 18 is connected to the water outlet pipe. In this process, the water injection pipe and the water outlet pipe are located in a protective shell 19 to prevent the pipe from tilting under the impact of the water flow inside the pipe. The cold air and cold water are respectively injected into the space between the glass 11 and the inside of the cooling box 13 through the air injection interface 15 and the water injection interface 17. At this time, power is turned on to make the PCB lamp board 12 and the display circuit board 14 run, and the electronic components on the PCB lamp board 12 emit light, so that the emitted infrared light passes through the glass 11 under the PCB lamp board 12 and irradiates under the glass 11, so that the silicon wafers and silicon chips that need to be soldered on the conveyor belt under the glass 11 pass under the main body 1. When irradiated by infrared light, the molecules on the surface of the irradiated silicon wafers and silicon chips absorb the energy of the infrared radiation and convert the absorbed infrared radiation energy into heat energy, rapidly increasing the temperature inside the silicon wafers and silicon chips, thereby solidifying them. When the electronic components on the PCB lamp board 12 are in operation, the temperature of the area between the glass 11 and the cooling box 13 increases, which in turn causes the temperature of the PCB lamp board 12 to increase. According to the law of heat conduction, heat is always transferred from a high-temperature area to a low-temperature area. Therefore, through the glass 11 and the cooling box 13, it is absorbed by the cold air and cold water inside them, causing the temperature of the cold air and cold water to increase, and also causing the temperature of the area where the PCB lamp board 12 is located to decrease, thereby reducing the temperature of the PCB lamp board 12. As the cold air and cold water are continuously injected, the cold air and cold water that have absorbed heat in the glass 11 and the cooling box 13 are discharged through the muffler 16 and the drainage interface 18 respectively.

[0038] The present invention inputs cold air and cold water into the enclosed space within the glass 11 and the cooling box 13 respectively through the air injection interface 15 and the water injection interface 17, thereby reducing the temperature of the PCB lamp board 12 between the cooling box 13 and the glass 11 during operation, preventing the performance and life of the electronic components on the PCB lamp board 12 from being reduced under long-term high-temperature operation, thereby avoiding frequent replacement of the PCB lamp board 12 and ensuring more stable operation of the PCB lamp board 12.

[0039] During long-term use, when the pipe connection at the water injection interface 17 becomes loose and leaks, the leaked water triggers the early warning component, which then sounds an alarm, ensuring that the staff is aware of the loose pipe at the water injection interface 17 causing the leakage, thereby avoiding the problem that the loose pipe at the water injection interface 17 causes the amount of cold water entering the cooling box 13 to be reduced, thereby causing the temperature of the PCB lamp board 12 to rise during operation, reducing the performance and life of the electronic components on the PCB lamp board 12, and causing the curing effect to deteriorate, thereby ensuring the stability of the curing.

[0040] like Figure 1 and Figure 2As shown, in this embodiment, an ultra-bright high-power IR940 light source is provided on the PCB light board 12, the display circuit board 14 is electrically connected to the PCB light board 12, and the display circuit board 14 can be communicatively connected with the controller.

[0041] Specifically, the ultra-bright high-power IR940 light source has a fast curing speed, and the display circuit board 14 can be remotely controlled by the controller, so that the staff can better understand the curing status of the product.

[0042] like Figure 1 and Figure 2 As shown, the PCB lamp board 12 of this embodiment is located in a closed space between the glass 11 near the middle of the main body 1 and the cooling box 13 , and a closed space is formed between the glass 11 near the middle of the main body 1 and the cooling box 13 .

[0043] Specifically, the PCB light board 12 is located in a confined space between the glass 11 near the middle of the main body 1 and the cooling box 13, so that the electronic components on the PCB light board 12 are not in contact with the external environment, thereby preventing the electronic components on the PCB light board 12 from being contaminated by the external environment. At the same time, when the electronic components on the PCB light board 12 emit light, the temperature in the confined space increases, and then the temperature is reduced through the glass 11 and the cooling box 13.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, an arc-shaped opening is provided at the bottom of the protective shell 19.

[0045] Specifically, an arc-shaped opening is provided at the bottom of the protective shell 19 to facilitate the fixation of the water injection interface 17 and the drainage interface 18 to the connection points of the water injection pipe and the water outlet pipe thereon.

[0046] like Figures 1 to 4As shown, the early warning component of this embodiment includes a collection tank 21, the collection tank 21 is fixedly connected to the surface of the water injection interface 17, the collection tank 21 is fixedly connected to a guide tube 23 on the side away from the middle of the main body 1, the guide tube 23 is communicated with the collection tank 21, and the guide tube 23 is provided with a protective shell 22 at one end away from the collection tank 21, the protective shell 22 is fixedly connected to the top of the main body 1, the protective shell 22 is fixedly connected to a rotating shaft 24, the surface of the rotating shaft 24 is rotatably connected to a rotating plate 25, and both ends of the rotating plate 25 are provided with a limiting ring 26 fixedly connected to the surface of the rotating shaft 24, the bottom end of the middle of the rotating plate 25 is fixedly connected to a resisting rod 27, and the middle of the inner wall of the bottom end of the protective shell 22 is provided with a A resistance groove 28 is provided, and a resistance groove 29 is provided at the bottom of one end of the rotating plate 25 close to the guide tube 23. A resistance rod 210 is fixedly connected to the inner wall surface of the bottom end of the protective shell 22 close to the guide tube 23. A counterweight 211 is fixedly connected to the top of the rotating plate 25 close to the guide tube 23. A collection box 212 is fixedly connected to the top of the rotating plate 25 close to the guide tube 23. The end of the guide tube 23 away from the water injection interface 17 is located in the collection box 212. An alarm 213 fixedly connected to the top of the main body 1 is provided on the side of the protective shell 22 away from the water injection interface 17. A wire is provided between the alarm 213 and the resistance groove 28, and the two ends of the wire are respectively connected to the alarm 213 and the resistance groove 28.

[0047] Specifically, when the pipe connection at the water injection interface 17 is loose and leaking, the leaked water flows into the collection tank 21 through the surface of the water injection interface 17, and then flows into the collection box 212 through the guide pipe 23. As the leaked water continues to flow into the collection box 212, the weight of the water stored in the collection box 212 increases, and then moves downward under the action of gravity, thereby driving the rotating plate 25 below it to move downward together, so that the rotating plate 25 rotates on the rotating shaft 24 with the rotating shaft 24 as the axis, and does not leak under the limiting action of the limiting ring 26. The rotating plate 25 rotates, driving the first interference rod 27 to slide above the first interference groove 28 until the weight of the water stored in the collection box 212 is consistent with the weight of the counterweight 211. At this time, the rotating plate 25 is in a horizontal state, the second interference groove 29 on the rotating plate 25 conflicts with the second interference rod 210, and the first interference rod 27 conflicts with the first interference groove 28. Under the action of the wire connecting the alarm 213 and the first interference groove 28, a circuit path is formed, and electricity is supplied through the second interference rod 210, causing the alarm 213 to sound an alarm.

[0048] In the present invention, the second interference groove 29 and the second interference rod 210 interfere with each other, and the first interference rod 27 and the first interference groove 28 interfere with each other, thereby forming a circuit path through the rotating plate 25, causing the alarm 213 to sound an alarm, ensuring that the staff is aware of the loose pipe at the water injection interface 17 causing leakage, thereby avoiding the problem that the loose pipe at the water injection interface 17 causes the amount of cold water entering the cooling box 13 to decrease, thereby causing the temperature of the PCB lamp board 12 to increase during operation, reducing the performance and life of the electronic components on the PCB lamp board 12, and causing the curing effect to deteriorate, thereby ensuring the stability of the curing.

[0049] As the amount of water stored in the alarm 213 continues to increase, the rotating plate 25 maintains a horizontal straight line state under the limiting effect of the second resistance rod 210.

[0050] like Figure 4 As shown, when the rotating plate 25 of this embodiment is in a horizontal state, the interference rod 1 27 fixed thereon interferes with the interference groove 1 28, and the interference rod 2 210 is located on the movement trajectory of the interference groove 29. When the interference groove 29 interferes with the interference rod 2 210, the interference rod 1 27 interferes with the interference groove 1 28.

[0051] Specifically, the second interference rod 210 is located on the movement trajectory of the second interference groove 29. When the weight of the water stored in the collection box 212 is equal to the weight of the counterweight 211, the rotating plate 25 is in a horizontal straight line state with the rotating shaft 24 as the axis. At this time, the second interference groove 29 and the second interference rod 210 are in conflict, and the first interference rod 1 27 and the first interference groove 1 28 are in conflict, and then they are connected under the action of the rotating plate 25 and the protective shell 2 22.

[0052] Example 2

[0053] like Figures 2 to 8 As shown, compared with Example 1, another embodiment of the present invention is:

[0054] like Figure 3 、 Figures 5 to 8 As shown, the protective shell 22 of this embodiment is provided with a guide block 31 fixedly connected to the top of the main body 1 on one side close to the middle of the main body 1, and a motion groove 32 is provided on the guide block 31. A threaded rod 33 is rotatably connected in the motion groove 32, and a displacement block 34 is slidably connected in the motion groove 32. The threaded rod 33 is threadedly connected to the displacement block 34, and a motor 35 is fixedly connected to the top of the guide block 31, and the output end of the motor 35 is fixed to the threaded rod 33.

[0055] Specifically, when the alarm 213 sounds, the motor 35 is started, and the threaded rod 33 is driven to rotate together through the output end of the motor 35. The rotation of the threaded rod 33 drives the displacement block 34 to displace on the threaded rod 33 and slide in the motion groove 32.

[0056] like Figure 3 、 Figures 5 to 8 As shown, a displacement thread collar is provided in the displacement block 34 of this embodiment, and the shape of the displacement thread collar in the displacement block 34 matches the shape of the displacement thread groove on the threaded rod 33 .

[0057] Specifically, the shape of the displacement threaded collar in the displacement block 34 matches the shape of the displacement threaded groove on the threaded rod 33, so that when the threaded rod 33 rotates, the displacement threaded collar in the displacement block 34 slides along the shape of the displacement threaded groove on the threaded rod 33, causing the displacement threaded collar in the displacement block 34 to be displaced, thereby driving the displacement block 34 to be displaced under the limiting action of the motion groove 32.

[0058] like Figures 5 to 8 As shown, in this embodiment, a sliding groove 36 is provided in the displacement block 34, and a rotating rod 38 is rotatably connected in the sliding groove 36. The rotating rod 38 is fixedly connected to the guide gear 39 on the end surface close to the guide block 31, and a rack plate 37 is fixedly connected in the motion groove 32. The rack plate 37 passes through the displacement block 34 and is connected to the sliding groove 36. The rack plate 37 is meshed with the guide gear 39. A guide thread groove 310 is symmetrically provided on the surface of the rotating rod 38. A limit block 311 is symmetrically slidably connected in the sliding groove 36. The limit block 311 is threadedly connected to the guide thread groove 310, and the end of the limit block 311 away from the displacement block 34 is located inside the protective shell 19.

[0059] The cam 311 is in the position that the cam 311 of the locking cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19. When the cam 311 is in the position that the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19, the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19. When the cam 311 is in the position that the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19, the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19. When the cam 311 is in the position that the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19, the cam 311 is positioned at the top of the arc-shaped opening on the protective shell 19.

[0060] The present invention uses the limit blocks 311 to move towards each other, so that the pipe connection at the water injection interface 17 is loose and leaks, which is clamped by the limit blocks 311, thereby slowing down the leakage rate and avoiding excessive cold water falling on the product below due to excessive leakage rate, resulting in poor curing effect due to the influence of cold water on the product during the curing process. At the same time, by slowing down the leakage rate, the staff has sufficient time to arrive at the scene and deal with it.

[0061] like Figures 5 to 8 As shown, a guide thread collar is provided in the limit block 311 of this embodiment, the guide thread collar on the limit block 311 matches the shape of the guide thread groove 310, the shape of the limit block 311 matches the shape of the water injection interface 17, and the end of the limit block 311 located inside the protective shell 19 is in the same vertical line as the water injection interface 17.

[0062] Specifically, the guide thread collar on the limit block 311 matches the shape of the guide thread groove 310, so that when the rotating rod 38 rotates, the guide thread groove 310 rotates along with the rotating rod 38, causing the guide thread collar on the limit block 311 to displace along the shape of the rotating rod 38, thereby driving the limit block 311 to slide toward each other in the sliding groove 36 under the limiting action of the sliding groove 36; the end of the limit block 311 located inside the protective shell 19 is in the same vertical straight line as the water injection interface 17, so that the limit block 311 moves symmetrically with the water injection interface 17 as the center when moving downward.

[0063] Working principle: Fix one end of the main body 1 on the wall so that the main body 1 is located above the conveyor belt. At this time, connect the air injection interface 15 and the water injection interface 17 to the cold air pipe and the water injection pipe respectively, and connect the drainage interface 18 to the water outlet pipe. In this process, the water injection pipe and the water outlet pipe are located in the protective shell 19 to prevent the pipe from tilting under the impact of the water flow inside it. Inject cold air and cold water into the space between the glasses 11 and the inside of the cooling box 13 through the air injection interface 15 and the water injection interface 17 respectively. At this time, turn on the power to make the PCB light board 12 and the display circuit board 14 run, and the electronic components on the PCB light board 12 emit light, so that the emitted infrared light passes through the glass 11 under the PCB light board 12 and shines under the glass 11, so that the silicon wafers and silicon chips that need to be soldered on the conveyor belt under the glass 11 are illuminated by the infrared light when passing under the main body 1. The molecules on the surface of the silicon wafers and silicon chips will absorb the energy of the infrared radiation and convert the absorbed infrared radiation energy into heat energy, causing the internal temperature of the silicon wafers and silicon chips to rise rapidly, thereby solidifying them. At the same time, the electronic components on the PCB lamp board 12 will increase the temperature of the area between the glass 11 and the cooling box 13 during operation, thereby causing the temperature of the PCB lamp board 12 to rise. According to the law of heat conduction, heat is always transferred from a high-temperature area to a low-temperature area. Therefore, it passes through the glass 11 and the cooling box 13 and is absorbed by the cold air and cold water inside them, causing the temperature of the cold air and cold water to rise, and also causing the temperature of the area where the PCB lamp board 12 is located to drop, thereby reducing the temperature of the PCB lamp board 12. As the cold air and cold water are continuously injected, the cold air and cold water that have absorbed heat in the glass 11 and the cooling box 13 are discharged through the muffler 16 and the drainage interface 18 respectively.

[0064] During long-term use, when the pipe connection at the water injection interface 17 becomes loose and leaks, the leaked water flows into the collection tank 21 through the surface of the water injection interface 17, and then flows into the collection box 212 through the guide pipe 23. As the leaked water continues to flow into the collection box 212, the weight of the water stored in the collection box 212 increases, and then moves downward under the action of gravity, thereby driving the rotating plate 25 below it to move downward together, so that the rotating plate 25 rotates on the rotating shaft 24 with the rotating shaft 24 as the axis, and within the limit of the limit ring 26, the rotating plate 25 rotates on the rotating shaft 24. The rotating plate 25 rotates to drive the interference rod 1 27 to slide above the interference groove 1 28 until the weight of the water stored in the collection box 212 is consistent with the weight of the counterweight 211. At this time, the rotating plate 25 is in a horizontal state, the interference groove 29 on the rotating plate 25 interferes with the interference rod 210, and the interference rod 1 27 interferes with the interference groove 1 28. Under the action of the connection of the wire between the alarm 213 and the interference groove 1 28, a circuit path is formed, and electricity is supplied through the interference rod 210, causing the alarm 213 to sound an alarm.

[0065] When the alarm 213 sounds, the motor 35 is started, and the threaded rod 33 is driven to rotate together through the output end of the motor 35. The rotation of the threaded rod 33 drives the displacement block 34 to move on the threaded rod 33 and slide in the motion groove 32. In the initial state, the limit block 311 in the displacement block 34 is located at the top of the arc-shaped opening on the protective shell 19. In the process of the displacement block 34 moving downward, the displaced displacement block 34 drives the limit block 311 to move together. At the same time, in this process, the guide gear 39 on the rotating rod 38 engages with the rack plate 37 and rotates. As the rod 38 moves along with the displacement block 34, the guide gear 39 drives the rotating rod 38 to rotate, and then the guide thread groove 310 on the rotating rod 38 is threadedly connected with the limit block 311, so that the limit block 311 moves toward each other, and then the limit block 311 moves toward the middle of the protective shell 19 until the displacement block 34 contacts the bottom of the movement groove 32. At this time, the limit block 311 is located outside the water injection interface 17 and clamps the water injection pipe connected to the water injection interface 17, so that its connection with the water injection interface 17 is tighter, thereby slowing down the speed of water leakage.
