Description

Technical Field

[0001] The present application relates to the technical field of laser packaging, and in particular to an automatic packaging device for laser production. Background Art

[0002] The automatic packaging of lasers mainly includes key steps such as chip preparation, chip eutectic, gold wire bonding, fiber coupling, sealing and shell assembly, and detection and testing. The shell assembly mainly uses a sealing welding machine to weld the tube seat and the tube cap. The tube seat and the tube cap are placed in different loading trays, and the tube seat and the tube cap are grabbed by the loading assembly to the welding head for welding.

[0003] Since semiconductor components are installed on the tube socket, attention should be paid to the storage environment of the tray when the tube socket is in the tray. Generally, the storage temperature of the laser tube socket is between -10℃ and 50℃, but some special types of laser tube sockets, such as tube sockets with specific packages or materials, require more stringent temperature control conditions. The storage temperature is basically between 5℃ and 30℃. The temperature difference in domestic cities is very large. The average winter temperature in northern cities is basically below 0℃. Too low temperature will make the laser tube socket brittle, which will affect the performance of the laser. Summary of the invention

[0004] The purpose of the present application is to provide an automatic packaging device for laser production, which can reduce the embrittlement of the laser tube holder in a low temperature environment and ensure the performance of the laser tube holder.

[0005] In the first aspect, the present application provides an automatic packaging device for laser production, which adopts the following technical solution: An automatic packaging device for laser production, comprising: A material tray, wherein the material tray is provided with a plurality of storage slots for accommodating the tube seats; A temperature control cover, which is arranged on the material tray and is used to isolate the pipe seat from external dust; A sealing welding machine head, the sealing welding machine head comprises an upper electrode position and a lower electrode position, the upper electrode position is used to fix the tube cap, the lower electrode position is used to fix the tube seat, the upper electrode position can move toward the lower electrode position to align the tube seat with the tube cap and weld; A clamping assembly, the clamping assembly is used to clamp the tube holder on the material tray to the lower electrode position and clamp the tube cap to the upper electrode position; A positioning assembly, the positioning assembly is used to adjust the tube seat to be aligned with the tube cap; The temperature control device includes a temperature sensor and a heating component arranged in the temperature control cover. The temperature sensor is used to monitor the temperature in the temperature control cover and control the heating component to increase the temperature in the temperature control cover.

[0006] Optionally, the heating assembly includes a heat exchange tube and a water collecting tank arranged in a temperature control cover, the water inlet end of the heat exchange tube is inserted from the top of the water collecting tank and fixed at the bottom of the water collecting tank, the water outlet end of the heat exchange tube is connected to the top of the water collecting tank, a water pump for transporting water to the water inlet end is provided in the water collecting tank, and a heater for heating water is also provided in the water collecting tank.

[0007] Optionally, the heat exchange tube is arranged on the inner wall of the temperature control cover, and the heat exchange tube is used to heat the temperature control cover to eliminate water mist attached to the inner wall of the temperature control cover.

[0008] Optionally, the heat exchange tube is provided with air holes, and the heat exchange tube is wrapped with a sponge cover.

[0009] Optionally, when the sponge cover is saturated, the water in the sponge cover can flow into the water collecting tank.

[0010] Optionally, a water collecting trough is provided on the water collecting box, and a water inlet hole connected to the inner cavity of the water inlet box is opened on the water collecting trough, and both ends of the sponge cover are located above the water collecting trough, so that water drops dripping from the sponge cover can fall into the water collecting trough.

[0011] Optionally, the heat exchange tubes are densely distributed on the inner top wall of the temperature control cover, the top plate of the temperature control cover is inclined, and the water collecting tank is arranged around the inner peripheral side wall of the temperature control cover.

[0012] Optionally, the water collection trough is designed with a height difference, and the water inlet hole is arranged at the lower water trough to improve the drainage efficiency of the water collection trough.

[0013] Optionally, a positioning assembly is further included, wherein the positioning assembly includes a first positioning clamp and a second positioning clamp arranged on both sides of the lower electrode position, and the first positioning clamp and the second positioning clamp move toward each other to position the tube seat.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: 1. Remove the temperature control cover, clamp the tube holder placed on the material tray to the lower electrode position with the clamping assembly, clamp the tube cap to the upper electrode position, adjust the position of the tube holder with the positioning assembly so that it is aligned with the tube cap, move the upper electrode position toward the lower electrode position, place the tube cap on the tube holder and fix it by welding.

[0015] The temperature control cover covers the material tray, which can reduce the possibility of dust accumulation in the interface, plug and other parts of the tube holder, ensuring the performance of the laser. At the same time, the temperature control cover can also keep the material tray warm, reducing the temperature drop in the temperature control cover, which is beneficial to the preservation of the laser base.

[0016] When the outdoor temperature drops, causing the temperature inside the temperature control cover to be lower than the storage standard, the temperature sensor controls the heating component to heat the temperature control cover according to the detected temperature, thereby increasing the temperature inside the temperature control cover to reach the standard storage temperature of the laser tube holder, reducing the embrittlement of the laser tube holder in a low temperature environment and ensuring the performance of the laser tube holder.

[0017] 2. When the temperature inside the temperature control hood is too low, the heater heats the water in the water collecting tank, and the water pump transports the hot water to the heat exchange tube. The heat exchange tube generates heat and can increase the temperature inside the temperature control hood. The heat exchange tube and the water collecting tank form a closed flow path. On the one hand, it can save water resources and reduce water waste. On the other hand, the heater can continuously heat the water in the water collecting tank to ensure that the temperature of the hot water flowing in the heat exchange tube is not easy to decrease, thereby improving the temperature control effect of the heat exchange tube.

[0018] 3. When the external temperature drops too much, the temperature inside the temperature control hood will drop accordingly. However, since the temperature control hood has a heat preservation effect, the temperature inside the temperature control hood will form a temperature difference with the external temperature. When the water vapor in the temperature control hood encounters the colder inner wall of the temperature control hood, water mist will form on the inner wall of the temperature control hood, and the water mist will accelerate the oxidation of the surface of the tube seat, causing corrosion or internal circuit short circuit and other problems. On the one hand, the heat exchange tube is arranged on the inner wall of the temperature control hood, and the heat exchange tube is in direct contact with the inner wall of the temperature control hood. When the heat exchange tube is exchanging heat, it can quickly increase the temperature of the inner wall of the temperature control hood, thereby eliminating the water mist on the inner wall of the temperature control hood and even making it difficult for the water vapor to condense into water droplets on the temperature control hood to form water mist, thereby reducing the oxidation of the tube seat by water mist, and further protecting the tube seat. On the other hand, during the heat exchange process, the heat exchange tube can also increase the temperature inside the temperature control hood, so that the temperature inside the temperature control hood rises to the standard storage temperature of the tube seat, thereby playing the role of heating and demisting.

[0019] 4. Since the air in the northern region is relatively dry in winter, and the storage conditions of the tube socket have certain requirements for humidity, when the humidity in the temperature control cover is too low, the environment in the temperature control cover gradually becomes dry, which is easy to cause static electricity, thereby damaging the semiconductor components. When the heat exchange tube is heated, the water vapor generated by the hot water can pass through the air vents into the sponge cover. After the sponge cover absorbs the water vapor, it can slowly release the water vapor into the temperature control cover, thereby increasing the humidity in the temperature control cover. When the heating component stops heating, the sponge cover can release the stored water, slowly humidify, and reduce the situation where static electricity is easy to appear on the tube socket. In addition, the sponge cover can slow down the humidification efficiency by closing the air vents, reduce the increase of humidity in the temperature control cover due to the direct discharge of water vapor from the air vents, and reduce the excessive increase of humidity in the temperature control cover that exceeds the storage standard of the tube socket, thereby protecting the storage environment of the tube socket.

[0020] At the same time, the sponge sleeve can also absorb the water mist attached to the inner wall of the temperature control cover, reducing the possibility of water droplets formed by the water mist dripping from the inner wall of the temperature control cover to the pipe seat, reducing the adverse effect of the water mist on the pipe seat, and protecting the pipe seat.

[0021] 5. When the sponge cover is saturated, water will drip from the sponge cover, and the water droplets will flow along the low direction of the sponge cover. Both ends of the heat exchange tube are arranged on the water collecting tank, and the heights of both ends of the heat exchange tube are lower than the height of the middle part of the heat exchange tube. Therefore, the water droplets on the sponge cover will flow into the water collecting tank along both ends of the heat exchange tube, reducing the possibility of water droplets on the sponge cover falling onto the tube seat, and at the same time, the water on the sponge cover is recycled, saving water resources and forming a water circulation system.

[0024] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0025] An automatic packaging equipment for laser production, referring to Figure 1 and Figure 2 , including a material tray 1, a temperature control cover 2, a sealing and welding head 3, a clamping component 4, a positioning component 5, and a temperature control device 6. The sealing and welding head 3 includes an upper electrode position 31 for adsorbing the laser tube cap and a lower electrode position 32 for adsorbing the laser tube seat. The upper electrode position 31 is located above the lower electrode position 32 and can move toward the lower electrode position 32 to place the tube cap on the tube seat and release the capacitor to weld the tube cap and the tube seat together.

[0026] Reference Figure 1The positioning assembly 5 includes a first positioning clamp 51 and a second positioning clamp 52 arranged on both sides of the lower electrode position 32. The first positioning clamp 51 and the second positioning clamp 52 can both move toward the lower electrode position 32. The first positioning clamp 51 and the second positioning clamp 52 can push the tube holder to move on the lower electrode position 32, so that the tube holder moves to the center of the lower electrode position 32, thereby improving the docking accuracy between the tube cap and the tube holder.

[0027] Reference Figure 2 The material tray 1 is provided with a plurality of storage slots 11 for accommodating the tube holder, and the clamping assembly 4 is arranged on the side wall of the sealing and welding machine head 3, and is used to clamp the tube holder in the storage slot 11 to the lower electrode position 32. The temperature control cover 2 is arranged on the material tray 1 to reduce the possibility of dust accumulation on the interface, plug and other parts of the tube holder, and ensure the performance of the laser. At the same time, the temperature control cover 2 can also play a heat preservation effect on the material tray 1, reduce the variation range of the temperature drop in the temperature control cover 2, and is conducive to the preservation of the laser base.

[0028] Remove the temperature control cover 2, clamp the tube holder placed on the material tray 1 to the lower electrode position 32 with the clamping assembly 4, clamp the tube cap to the upper electrode position 31, and adjust the position of the tube holder with the positioning assembly 5 so that it is aligned with the tube cap. Move the upper electrode position 31 toward the lower electrode position 32, place the tube cap on the tube holder and fix it by welding.

[0029] Since the storage temperature of some special laser tube holders is above 5°C, and the average winter temperature in northern cities in China is basically below 0°C, too low a temperature will cause the laser tube holder to become brittle, thus affecting the performance of the laser.

[0030] Reference Figure 2 and Figure 3 The temperature control device 6 includes a temperature sensor 61 and a heating component 62 arranged inside the temperature control cover 2. The temperature control sensor is arranged on the inner wall of the temperature control cover 2 and is used to monitor the temperature inside the temperature control cover 2. When the temperature is lower than the storage temperature of the tube holder, the temperature control sensor transmits a signal to the heating component 62. The heating component 62 is used to heat the temperature control cover 2, thereby increasing the temperature inside the temperature control cover 2 to reach the standard storage temperature of the laser tube holder, reducing the embrittlement of the laser tube holder in a low temperature environment, and ensuring the performance of the laser tube holder.

[0031] Reference Figure 2 and Figure 3The heating assembly 62 includes a water collecting tank 622 and a heat exchange tube 621. The water collecting tank 622 is arranged at the bottom of the material tray 1. The water inlet end of the heat exchange tube 621 is inserted from the top of the water collecting tank 622 and fixed at the bottom of the water collecting tank 622. A water pump 623 is arranged in the water collecting tank 622. The water pump 623 is used to input the water in the water collecting tank 622 from the water inlet end into the heat exchange tube 621. A heater 624 is also arranged in the water collecting tank 622. The heater 624 is used to heat the water in the water collecting tank 622, so as to ensure that the water temperature in the heat exchange tube 621 is not easy to drop. The water outlet end of the heat exchange tube 621 is connected to the top of the water collecting tank 622, so as to transport the cooled water to the water collecting tank 622 for reheating circulation.

[0032] When the temperature inside the temperature control cover 2 is too low, the heater 624 heats the water in the water collecting tank 622, and the water pump 623 transports the hot water to the heat exchange tube 621. The heat exchange tube 621 generates heat and can increase the temperature inside the temperature control cover 2. The heat exchange tube 621 and the water collecting tank 622 form a closed flow path. On the one hand, the water flowing in the heat exchange tube 621 can enter the water collecting tank 622 and be heated and reused again, which can save water resources and reduce water waste. On the other hand, the heater 624 can continuously heat the water in the water collecting tank 622 to ensure that the temperature of the hot water flowing in the heat exchange tube 621 is not easy to decrease, thereby improving the temperature control effect of the heat exchange tube 621.

[0033] Reference Figure 2 and Figure 3 The top plate of the temperature control cover 2 is tilted, the heat exchange tube 621 is densely distributed on the inner wall of the temperature control cover 2, the heat exchange tube 621 is provided with air holes 625, the heat exchange tube 621 is wrapped with a circle of sponge sleeve 626, the outer side of the material tray 1 is surrounded by a water collecting trough 7, the water collecting trough 7 is arranged above the water collecting box 622, the bottom of the water collecting trough 7 is provided with a water inlet hole 71 connected with the water collecting box 622, the water collecting trough 7 is designed with a height difference, and the water inlet hole 71 is arranged at the low water tank, so as to improve the drainage effect of the water collecting trough 7. The two ends of the heat exchange tube 621 are respectively inserted into the water collecting box 622 from the water collecting trough 7, and the water collecting trough 7 is arranged below the heat exchange tube 621 on the inner wall of the temperature control cover 2, and the excess water in the sponge sleeve 626 can drip into the water collecting trough 7 along the heat exchange tube 621.

[0034] When the outside temperature drops too much, the temperature inside the temperature control cover 2 will drop accordingly. However, since the temperature control cover 2 has a heat preservation effect, the temperature inside the temperature control cover 2 will form a temperature difference with the outside temperature. When the water vapor in the temperature control cover 2 encounters the colder inner wall of the temperature control cover 2, water mist will form on the inner wall of the temperature control cover 2, and the water mist will accelerate the oxidation of the surface of the tube seat, causing corrosion or internal circuit short circuit and other problems. On the one hand, the heat exchange tube 621 is in direct contact with the inner wall of the temperature control cover 2, and the heat exchange tube 621 is densely distributed on the inner wall of the temperature control cover 2, which increases the contact area between the heat exchange tube 621 and the temperature control cover 2. When the heat exchange tube 621 exchanges heat, it can quickly increase the temperature of the inner wall of the temperature control cover 2, thereby eliminating the water mist on the inner wall of the temperature control cover 2 and even making it difficult for the water vapor to condense into water droplets on the temperature control cover 2 to form water mist, thereby reducing the oxidation of the tube seat by the water mist, and further protecting the tube seat. On the other hand, the heat exchange tube 621 can also increase the temperature inside the temperature control cover 2 during the heat exchange process, so that the temperature inside the temperature control cover 2 rises to the standard storage temperature of the tube seat, thereby achieving the functions of heating and demisting.

[0035] When water mist appears on the inner wall of the temperature control cover 2, the sponge cover 626 sleeved on the heat exchange tube 621 can absorb the water mist attached to the inner wall of the temperature control cover 2, reduce the possibility of water droplets formed by the water mist dripping from the inner wall of the temperature control cover 2 to the tube seat, reduce the adverse effect of the water mist on the tube seat, and protect the tube seat.

[0036] Since the air in the northern region is relatively dry in winter, and the storage conditions of the tube socket have certain requirements for humidity, when the humidity in the temperature control cover 2 is too low, the environment in the temperature control cover 2 gradually becomes dry, which easily leads to the generation of static electricity, thereby damaging the semiconductor components. When the heat exchange tube 621 is heated, the water vapor generated by the hot water can pass through the air vent 625 into the sponge cover 626. After the sponge cover 626 absorbs the water vapor, it can slowly release the water vapor into the temperature control cover 2, thereby increasing the humidity in the temperature control cover 2. When the heating component 62 stops heating, the sponge cover 626 can release the stored water, slowly humidify, and reduce the situation where static electricity is easy to appear on the tube socket.

[0037] Moreover, the sponge cover 626 seals the air hole 625 to slow down the humidification efficiency, reduce the humidity increase in the temperature control cover 2 due to the direct discharge of water vapor from the air hole 625, and reduce the humidity increase in the temperature control cover 2 that exceeds the storage standard of the tube holder, thereby protecting the storage environment of the tube holder.

[0038] When the sponge cover 626 absorbs too much water vapor from the air holes 625 and too much water mist from the inner wall of the temperature control cover 2, causing the sponge cover 626 to be saturated, the water in the sponge cover 626 will drip onto the tube seat, thereby affecting the performance of the semiconductor parts on the tube seat. The top plate of the temperature control cover 2 is tilted, and the heat exchange tube 621 fixed on the inner top wall of the temperature control cover 2 is parallel to the top plate of the temperature control cover 2. The water on the sponge cover 626 will be guided along the tilt direction of the heat exchange tube 621 to the heat exchange tube 621 on the side wall of the temperature control cover 2, and drip into the water collection tank 7 along the vertical direction of the temperature control cover 2. The water in the water collection tank 7 flows along the slope and flows into the water collection tank 622 from the water inlet 71.

[0039] When the sponge sleeve 626 is saturated, the water in the sponge sleeve 626 will drip into the water collecting tank 7 along the layout direction of the heat exchange tube 621, thereby reducing the possibility of the water in the sponge sleeve 626 dripping onto the tube seat. At the same time, the height difference of the water collecting tank 7 can discharge the water in the water collecting tank 7 into the water collecting box 622 as soon as possible, reducing the possibility of the water in the water collecting tank 7 evaporating and causing the humidity in the temperature control cover 2 to increase significantly, ensuring the humidity value in the temperature control cover 2, and improving the preservation effect of the tube seat. The water in the water collecting tank 7 flows into the water collecting box 622 and can be reused, saving water resources and forming a water circulation system in the temperature control cover 2.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
