Description

Technical Field

[0001] The invention belongs to the technical field of light source curing, in particular to an infrared curing light source. Background Art

[0002] With the continuous advancement of industrial informatization, the efficiency requirements for silicon wafer and silicon chip welding are also constantly increasing. The traditional infrared heating rod curing method is often used for heating and curing of solder, but it has problems such as long consumption time, uneven heating effect and short life of infrared rods, which leads to increased production costs. In addition, the machine needs to be shut down when replacing the infrared rod, which reduces production efficiency. Therefore, using 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 conveyor belt. The infrared LED lamp on the PCB light board emits light, so that the infrared light passes through the glass under the PCB light board and irradiates under the glass, so that the silicon wafers and silicon chips that need to be welded on the conveyor belt are irradiated by the infrared light when passing under the infrared curing light source. 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, so that the internal temperature of the silicon wafers and silicon chips rises rapidly, and then they are cured; at the same time, the temperature of the PCB light board is reduced through the water cooling and air cooling system in the infrared curing light source.

[0004] There are still some problems in the use of existing infrared curing light sources. For the water cooling system of the existing infrared curing light source, the pipes at the water injection interface will age during long-term use, resulting in weakened elasticity of the pipes at the water injection interface. At the same time, during the water cooling process, the cold water output from the pipe at the water injection interface comes into contact with the surrounding hot water, resulting in temperature changes in the pipe material, thereby causing thermal expansion and contraction. If this continues for a long time, stress will be generated at the pipe connection at the water injection interface, resulting in loosening of the pipe connection at the water injection interface, and further resulting in partial loss of water-cooling liquid, which reduces the cooling effect. The reduction in cooling effect will cause the temperature of the PCB lamp board to rise. Under long-term high-temperature operation, the performance and life of the electronic components on the PCB lamp board will be reduced.

[0005] To this end, the present invention provides an infrared curing light source. Summary of the invention

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

[0034] Embodiment 1

[0035] like Figures 1 to 8As shown, an infrared curing light source described in 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 arranged 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 arranged 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 The device 16, the gas injection interface 15 and the silencer 16 are both connected to the enclosed space between the two pieces of glass 11, the top of the main body 1 near the gas injection interface 15 is symmetrically fixedly connected with a water injection interface 17, the water injection interface 17 is connected to the cooling box 13 below it, one side of the water injection interface 17 is provided with an early warning component, the early warning component is used to sound an alarm when there is water leakage at the interface between the water injection interface 17 and the water pipe, the top of the main body 1 near the silencer 16 is symmetrically fixedly connected with a drainage interface 18, the drainage interface 18 is connected to the cooling box 13 below it, and 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, resulting in temperature changes in the pipe material, thereby causing thermal expansion and contraction. If this continues for a long time, stress will be generated at the pipe connection at the water injection interface 17, resulting in loosening of the pipe connection at the water injection interface 17, and further resulting in partial loss of water-cooling liquid, which reduces 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 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 light board 12 and the display circuit board 14 operate, 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 irradiates under the glass 11, so that the silicon wafers and silicon chips that need to be welded 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 wafer and silicon chip absorb the energy of infrared radiation and convert the absorbed infrared radiation energy into heat energy, so that the internal temperature of the silicon wafer and silicon chip rises rapidly, and then solidifies them; the electronic components on the PCB lamp board 12 increase the temperature of the area between the glass 11 and the cooling box 13 during operation, which leads to an increase in the temperature of the PCB lamp board 12. 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, which increases the temperature of the cold air and cold water, and also reduces the temperature in the area where the PCB lamp board 12 is located, 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 absorb 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 in the glass 11 and the cooling box 13 respectively through the air injection interface 15 and the water injection interface 17, so that the temperature of the PCB lamp board 12 between the cooling box 13 and the glass 11 is reduced 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 making the PCB lamp board 12 operate more stably.

[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 in turn 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 amount of cold water entering the cooling box 13 is reduced due to the loose pipe leakage at the water injection interface 17, thereby increasing the temperature of the PCB lamp board 12 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 lamp board 12 is located in a closed 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 lamp board 12 are not in contact with the external environment, thereby preventing the electronic components on the PCB lamp board 12 from being contaminated by the external environment. At the same time, when the electronic components on the PCB lamp board 12 emit light, the temperature in the closed 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 fixing 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 respectively.

[0046] like Figures 1 to 4As shown, the early warning component described in this embodiment includes a collecting groove 21, and the collecting groove 21 is fixedly connected to the surface of the water injection interface 17. A guide tube 23 is fixedly connected to the side of the collecting groove 21 away from the middle of the main body 1, and the guide tube 23 is connected to the collecting groove 21. A protective shell 22 is provided at one end of the guide tube 23 away from the collecting groove 21. The protective shell 22 is fixedly connected to the top of the main body 1. A rotating shaft 24 is fixedly connected inside the protective shell 22. A rotating plate 25 is rotatably connected to the surface of the rotating shaft 24. Limiting rings 26 fixedly connected to the surface of the rotating shaft 24 are provided at both ends of the rotating plate 25. A resisting rod 27 is fixedly connected to the bottom end of the middle part of the rotating plate 25. The middle part of the inner wall of the bottom end of the protective shell 22 is provided with a A resistance groove 28 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 away from the guide tube 23, a collecting 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 collecting 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 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 does not leak under the limiting action of the limiting ring 26. The rotating plate 25 rotates to drive the contact rod 27 to slide above the contact 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 contact groove 29 on the rotating plate 25 contacts the contact rod 210, and the contact rod 27 contacts the contact groove 28. Under the connection of the wire between the alarm 213 and the contact groove 28, a circuit path is formed, and the contact rod 210 is energized to make the alarm 213 sound an alarm.

[0048] The present invention forms a circuit path through the contact groove 29 and the contact rod 210, and the contact rod 1 27 and the contact groove 1 28 at the same time, and then the rotating plate 25 forms a circuit path, so that the alarm 213 sounds an alarm, ensuring that the staff knows that the pipe at the water injection interface 17 is loose and causes water leakage, avoiding the problem that the amount of cold water entering the cooling box 13 is reduced due to the loose pipe leakage at the water injection interface 17, and then the temperature of the PCB lamp board 12 is increased during operation, which reduces the performance and life of the electronic components on the PCB lamp board 12 and causes the curing effect to deteriorate, thereby ensuring the stability of 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 resistance rod 1 27 fixed thereon resists against the resistance groove 1 28 , and the resistance rod 2 210 is located on the movement trajectory of the resistance groove 29 , and the resistance groove 29 resists against the resistance rod 2 210 while the resistance rod 1 27 resists against the resistance groove 1 28 .

[0051] Specifically, the friction rod 210 is located on the movement trajectory of the friction 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 friction groove 29 and the friction rod 210 are in conflict, and the friction rod 1 27 and the friction 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] Embodiment 2

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

[0054] like Figure 3 , Figures 5 to 8 As shown, in this embodiment, a guide block 31 fixedly connected to the top of the main body 1 is provided on one side of the protective shell 22 close to the middle of the main body 1, and a motion groove 32 is opened 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, in this embodiment, a displacement thread collar is provided in the displacement block 34 , 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. A guide gear 39 is fixedly connected to the surface of one end of the rotating rod 38 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] Specifically, in the initial state, the limit block 311 in the displacement block 34 is located at the top of the arc-shaped opening opened on the protective shell 19. During the downward displacement of the displacement block 34, the displaced displacement block 34 drives the limit block 311 to move together. At the same time, during this process, the guide gear 39 on the rotating rod 38 meshes with the rack plate 37, and the guide gear 39 drives the rotating rod 38 to rotate under the action of the displacement of the rotating rod 38 along with the displacement block 34. Then, through the threaded connection between the guide thread groove 310 on the rotating rod 38 and the limit block 311, the limit block 311 moves towards 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 it is closely connected to the water injection interface 17, thereby slowing down the speed of water leakage.

[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 loosened and leaks, and is clamped by the limit blocks 311, thereby slowing down the speed of water leakage and preventing excessive cold water from falling on the product below due to excessive leakage, resulting in poor curing effect during the curing process due to the influence of cold water on the product. At the same time, by slowing down the speed of water leakage, the staff has sufficient time to arrive at the site and deal with it.

[0061] like Figures 5 to 8 As shown, in this embodiment, a guide thread ring is arranged inside the limit block 311, and the guide thread ring on the limit block 311 matches the shape of the guide thread groove 310, and 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 together with the rotating rod 38, causing the guide thread collar on the limit block 311 to be displaced 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; one 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 with the water injection interface 17 as the center of symmetry 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 a 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 operate, 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 irradiates under the glass 11, so that the silicon wafers and silicon chips that need to be welded on the conveyor belt under the glass 11 are irradiated by the infrared light when passing under the main body 1. The molecules on the surface of the silicon wafer and silicon chip will absorb the energy of the infrared radiation and convert the absorbed infrared radiation energy into heat energy, so that the internal temperature of the silicon wafer and silicon chip will rise rapidly, and then solidify 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, so that the temperature of the cold air and cold water rises, and the temperature in the area where the PCB lamp board 12 is located is reduced, 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 absorb 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 is 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 the limiting action of the limiting ring 26 is achieved. The rotating plate 25 rotates to drive the contact rod 27 to slide above the contact 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 contact groove 29 on the rotating plate 25 contacts the contact rod 210, and the contact rod 27 contacts the contact groove 28. Under the connection of the wire between the alarm 213 and the contact groove 28, a circuit path is formed, and the contact rod 210 is energized to make the alarm 213 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 opened 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 is engaged 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 threaded groove 310 on the rotating rod 38 is threadedly connected with the limit block 311, so that the limit block 311 moves towards each other, and then the limit block 311 moves toward the direction close to 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 the connection between it and the water injection interface 17 is tighter, thereby slowing down the speed of water leakage.
