Description

Technical Field

[0001] This application relates to the field of laser packaging technology, and in particular to an automated packaging device for laser production. Background Technology

[0002] The automated packaging of lasers mainly includes key steps such as chip preparation, chip eutectic bonding, gold wire bonding, fiber coupling, sealing and housing assembly, and inspection and testing. Among them, the housing assembly mainly uses a sealing and welding machine to weld the tube socket and the tube cap. The tube socket and the tube cap are placed in different material trays, and the feeding assembly picks up the tube socket and the tube cap and brings them to the welding head for welding.

[0003] Because the sockets contain semiconductor components, the storage environment of the tray is crucial when the sockets are in the tray. Generally, the storage temperature of laser sockets is between -10℃ and 50℃. However, some special types of laser sockets, such as those with specific packaging or materials, require more stringent temperature control conditions, with storage temperatures generally between 5℃ and 30℃. However, the temperature varies greatly among cities in China, with the average winter temperature in northern cities generally below 0℃. Excessively low temperatures can cause the laser sockets to become brittle, thus affecting the performance of the laser. Summary of the Invention

[0004] The purpose of this application is to provide an automated packaging device for laser production that can reduce the embrittlement of laser tube sockets in low-temperature environments and ensure the performance of laser tube sockets.

[0005] Firstly, this application provides an automated packaging device for laser production, which adopts the following technical solution:

[0006] An automated packaging device for laser production includes:

[0007] A material tray, wherein the material tray is provided with several storage slots for accommodating tube seats;

[0008] A temperature control cover is placed over the material tray and is used to isolate the tube socket from external dust.

[0009] A sealing welding head, comprising an upper electrode position and a lower electrode position, wherein the upper electrode position is used to fix the pipe cap and the lower electrode position is used to fix the pipe seat, and the upper electrode position can move toward the lower electrode position to align the pipe seat and the pipe cap and weld them;

[0010] A clamping assembly is used to clamp the tube seat on the material tray to the lower electrode position and the tube cap to the upper electrode position;

[0011] A positioning component for adjusting the tube seat to be aligned with the tube cap;

[0012] A temperature control device, comprising a temperature sensor and a heating component disposed within the temperature control cover, wherein the temperature sensor is used to monitor the temperature inside the temperature control cover and control the heating component to raise the temperature inside the temperature control cover.

[0013] Optionally, the heating assembly includes a heat exchange tube and a water collection tank disposed inside a temperature control cover. The inlet end of the heat exchange tube is inserted from the top of the water collection tank and fixed to the bottom of the water collection tank. The outlet end of the heat exchange tube is connected to the top of the water collection tank. A water pump is provided in the water collection tank to transport water to the inlet end. A heater for heating the water is also provided in the water collection tank.

[0014] 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 adhering to the inner wall of the temperature control cover.

[0015] Optionally, the heat exchange tube is provided with vent holes, and the heat exchange tube is wrapped with a sponge sleeve.

[0016] Optionally, when the sponge sleeve is saturated, the water in the sponge sleeve can flow into the water collection tank.

[0017] Optionally, the water collection tank is provided with a water collection trough, and the water collection trough has a water inlet hole that communicates with the inner cavity of the water inlet tank. Both ends of the sponge sleeve are located above the water collection trough, and water droplets dripping from the sponge sleeve can fall into the water collection trough.

[0018] Optionally, the heat exchange pipes 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 collection tank is arranged around the inner peripheral side wall of the temperature control cover.

[0019] Optionally, the water collection tank is designed with a height difference, and the water inlet is located at the lower water tank to improve the drainage efficiency of the water collection tank.

[0020] Optionally, a positioning component is also included, comprising a first positioning clamp and a second positioning clamp disposed on both sides of the lower electrode position, wherein the first positioning clamp and the second positioning clamp move toward each other to position the tube seat.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Remove the temperature control cover. The clamping assembly clamps the tube seat placed on the material tray to the lower electrode position and clamps the tube cap to the upper electrode position. The positioning assembly adjusts the position of the tube seat to align it with the tube cap. The upper electrode position moves toward the lower electrode position. The tube cap is placed on the tube seat and welded in place.

[0023] The temperature control cover seals the material tray, reducing the possibility of dust accumulation at the interfaces and plugs of the tube socket, ensuring the performance of the laser. At the same time, the temperature control cover also insulates the material tray, reducing the temperature fluctuation inside the cover, which is beneficial for the preservation of the laser base.

[0024] When the outdoor temperature drops, causing the temperature inside the temperature control enclosure to fall below the storage standard, the temperature sensor controls the heating component to heat the inside of the temperature control enclosure based on the detected temperature, thereby raising the temperature inside the temperature control enclosure to reach the standard storage temperature of the laser tube socket. This reduces the possibility of the laser tube socket becoming brittle in low-temperature environments and ensures the performance of the laser tube socket.

[0025] 2. When the temperature inside the temperature control hood is too low, the heater heats the water in the collection tank, and the water pump delivers the hot water to the heat exchange tube. The heat exchange tube heats up and can increase the temperature inside the temperature control hood. The heat exchange tube and the collection tank form a closed flow path. Firstly, it can save water resources and reduce water waste. Secondly, the heater can continuously heat the water in the collection tank, ensuring that the temperature of the hot water flowing in the heat exchange tube does not easily drop, thus improving the temperature control effect of the heat exchange tube.

[0026] 3. When the external temperature drops significantly, the temperature inside the temperature control cover will also decrease. However, due to the insulation effect of the temperature control cover, a temperature difference will form between the inside and outside temperatures. When water vapor inside the temperature control cover encounters the cooler inner wall, it will form water mist on the inner wall. This water mist will accelerate the oxidation of the tube socket surface, causing corrosion or internal circuit short circuits. On one hand, the heat exchange tubes are installed on the inner wall of the temperature control cover, directly contacting it. During heat exchange, the heat exchange tubes can quickly raise the temperature of the inner wall, thereby eliminating water mist and preventing water vapor from condensing into water droplets, thus reducing the oxidation of the tube socket and further protecting it. On the other hand, during heat exchange, the heat exchange tubes also raise the temperature inside the temperature control cover, bringing it up to the standard storage temperature of the tube socket, thus achieving the functions of heating and demisting.

[0027] 4. Due to the dry air in northern regions during winter, and the specific humidity requirements for tube socket storage, excessively low humidity inside the temperature control hood can lead to static electricity buildup, potentially damaging semiconductor components. When the heat exchange tubes are heated, the water vapor generated by the hot water passes through the vents into the sponge sleeve. The sponge sleeve absorbs the water vapor and slowly releases it into the temperature control hood, increasing humidity. When the heating element stops heating, the sponge sleeve releases the stored water, slowly humidifying the tube socket and reducing the likelihood of static electricity buildup. Furthermore, the sponge sleeve's seal on the vents slows down the humidification process, preventing excessive humidity buildup that could exceed storage standards and protecting the tube socket's storage environment.

[0028] At the same time, the sponge sleeve can also absorb the water mist adhering 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 onto the tube socket, reducing the adverse effects of water mist on the tube socket, and protecting the tube socket.

[0029] 5. When the sponge sleeve becomes saturated, water will drip from it. The water droplets will flow along the lower part of the sponge sleeve. Both ends of the heat exchange tube are set on the water collection tank, and the height of the two ends of the heat exchange tube is lower than the height of the middle part of the heat exchange tube. Therefore, the water droplets on the sponge sleeve will be guided to the water collection tank along the two ends of the heat exchange tube, reducing the possibility of water droplets falling onto the tube seat. At the same time, the water on the sponge sleeve is recycled and reused, saving water resources and forming a water circulation system. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0035] An automated packaging device for laser production, referenced Figure 1 and Figure 2 It includes a material tray 1, a temperature control cover 2, a sealing and welding head 3, a clamping assembly 4, a positioning assembly 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 towards the lower electrode position 32. The tube cap is placed on the tube seat and the capacitor is released to weld the tube cap and the tube seat together.

[0036] Reference Figure 1 The positioning component 5 includes a first positioning clamp 51 and a second positioning clamp 52 disposed on both sides of the lower electrode position 32. Both the first positioning clamp 51 and the second positioning clamp 52 can move toward the lower electrode position 32. The first positioning clamp 51 and the second positioning clamp 52 can push the tube seat to move on the lower electrode position 32, so that the tube seat moves to the center of the lower electrode position 32, thereby improving the docking accuracy of the tube cap and the tube seat.

[0037] Reference Figure 2 The material tray 1 has several storage slots 11 for accommodating tube sockets. The clamping assembly 4 is located on the side wall of the sealing and welding head 3 and is used to clamp the tube sockets in the storage slots 11 onto the lower electrode position 32. The temperature control cover 2 is placed on the material tray 1 to reduce the possibility of dust accumulation on the interface and plug of the tube sockets, ensuring the performance of the laser. At the same time, the temperature control cover 2 can also keep the material tray 1 warm, reducing the temperature drop within the temperature control cover 2, which is beneficial for the preservation of the laser base.

[0038] Remove the temperature control cover 2, clamp the tube seat placed on the material tray 1 to the lower electrode position 32, clamp the tube cap to the upper electrode position 31, and position the tube seat to align with the tube cap. Move the upper electrode position 31 toward the lower electrode position 32, place the tube cap on the tube seat and weld it in place.

[0039] Because the storage temperature of some special laser sockets is above 5℃, while the average winter temperature in northern cities in China is basically below 0℃, the low temperature will cause the laser socket to become brittle, thus affecting the performance of the laser.

[0040] Reference Figure 2 and Figure 3The temperature control device 6 includes a temperature sensor 61 and a heating component 62 disposed inside the temperature control cover 2. The temperature sensor is disposed 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 laser tube socket, the temperature 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 socket, reducing the embrittlement of the laser tube socket in low temperature environment, and ensuring the performance of the laser tube socket.

[0041] Reference Figure 2 and Figure 3 The heating assembly 62 includes a water collection tank 622 and a heat exchange tube 621. The water collection tank 622 is located at the bottom of the material tray 1. The water inlet of the heat exchange tube 621 is inserted from the top of the water collection tank 622 and fixed to the bottom of the water collection tank 622. A water pump 623 is installed in the water collection tank 622 to pump water from the water inlet into the heat exchange tube 621. A heater 624 is also installed in the water collection tank 622 to heat the water in the water collection tank 622, thereby ensuring that the water temperature in the heat exchange tube 621 does not drop easily. The water outlet of the heat exchange tube 621 is connected to the top of the water collection tank 622, thereby transporting the cooled water back to the water collection tank 622 for reheating and circulation.

[0042] When the temperature inside the temperature control hood 2 is too low, the heater 624 heats the water in the water collection tank 622, and the water pump 623 delivers the hot water to the heat exchange tube 621. The heat exchange tube 621 heats up and can increase the temperature inside the temperature control hood 2. The heat exchange tube 621 and the water collection tank 622 form a closed flow path. Firstly, the water flowing in the heat exchange tube 621 can enter the water collection tank 622 for reheating and reuse, which can save water resources and reduce water waste. Secondly, the heater 624 can continuously heat the water in the water collection tank 622, ensuring that the temperature of the hot water flowing in the heat exchange tube 621 does not easily drop, thus improving the temperature control effect of the heat exchange tube 621.

[0043] Reference Figure 2 and Figure 3The top plate of the temperature control cover 2 is inclined, and heat exchange tubes 621 are densely distributed on the inner wall of the temperature control cover 2. Ventilation holes 625 are opened on the heat exchange tubes 621, and a sponge sleeve 626 is wrapped around the heat exchange tubes 621. A water collection trough 7 is arranged around the outer side of the material tray 1, and the water collection trough 7 is located above the water collection tank 622. A water inlet hole 71 communicating with the water collection tank 622 is opened at the bottom of the water collection trough 7. The water collection trough 7 is designed with a height difference, and the water inlet hole 71 is located at the lower part of the trough to improve the drainage effect of the water collection trough 7. Both ends of the heat exchange tubes 621 are inserted into the water collection tank 622 from the water collection trough 7. The water collection trough 7 is located below the heat exchange tubes 621 on the inner wall of the temperature control cover 2, allowing excess water in the sponge sleeve 626 to drip down the heat exchange tubes 621 into the water collection trough 7.

[0044] When the external temperature drops excessively, the temperature inside the temperature control cover 2 will also drop. However, due to the insulation effect of the temperature control cover 2, a temperature difference will form between the internal and external temperatures. When water vapor inside the temperature control cover 2 encounters the cooler inner wall of the temperature control cover 2, it will form water mist on the inner wall. This water mist will accelerate the oxidation of the tube socket surface, causing corrosion or internal circuit short circuits. On the other 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, increasing 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 raise the temperature of the inner wall of the temperature control cover 2, thereby eliminating water mist on the inner wall of the temperature control cover 2 and even making it difficult for water vapor to condense into water droplets on the temperature control cover 2, thus reducing the oxidation of the tube socket by water mist and further protecting the tube socket. On the other hand, during the heat exchange process, the heat exchange tube 621 can also increase the temperature inside the temperature control cover 2, so that the temperature inside the temperature control cover 2 rises to the standard storage temperature of the tube seat, thereby playing the functions of heating and demisting.

[0045] When water mist appears on the inner wall of the temperature control cover 2, the sponge sleeve 626 fitted on the heat exchange tube 621 can absorb the water mist adhering 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 onto the tube seat, reduce the adverse effects of water mist on the tube seat, and protect the tube seat.

[0046] Because the air in northern regions is relatively dry in winter, and the storage conditions for the tube sockets require a certain level of humidity, when the humidity inside the temperature control cover 2 is too low, the environment inside the cover 2 gradually dries out, easily leading to static electricity and thus damaging the semiconductor components. When the heat exchange tube 621 is heated, the water vapor generated by the hot water can pass through the vent 625 into the sponge sleeve 626. After absorbing the water vapor, the sponge sleeve 626 can slowly release the water vapor into the temperature control cover 2, thereby increasing the humidity inside the cover 2. When the heating element 62 stops heating, the sponge sleeve 626 can release the stored water, slowly humidifying the area and reducing the likelihood of static electricity forming on the tube sockets.

[0047] Furthermore, the sponge sleeve 626 seals the vent 625, which can slow down the humidification efficiency and reduce the occurrence of humidity increase inside the temperature control cover 2 due to the direct release of water vapor from the vent 625. This reduces the risk of humidity exceeding the storage standard of the tube socket due to excessively rapid humidity increase inside the temperature control cover 2, thus protecting the storage environment of the tube socket.

[0048] When the sponge sleeve 626 absorbs too much water vapor from the vent 625 and too much water mist from the inner wall of the temperature control cover 2, causing the sponge sleeve 626 to become saturated, the water in the sponge sleeve 626 will drip onto the tube socket, thus affecting the performance of the semiconductor components on the tube socket. The top plate of the temperature control cover 2 is inclined, and the heat exchange tube 621 fixed on the inner top wall of the temperature control cover 2 is arranged parallel to the top plate of the temperature control cover 2. The water on the sponge sleeve 626 will be guided along the inclined 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 down along the vertical direction of the temperature control cover 2 into the water collection tank 7. The water in the water collection tank 7 flows along the slope and flows into the water collection box 622 from the water inlet 71.

[0049] When the sponge sleeve 626 is saturated, the moisture in the sponge sleeve 626 will drip down along the arrangement direction of the heat exchange tube 621 into the water collection tank 7, thereby reducing the possibility of water dripping from the sponge sleeve 626 onto the tube seat. At the same time, the height difference designed in the water collection tank 7 can quickly drain the moisture in the water collection tank 7 into the water collection box 622, reducing the possibility of moisture evaporation in the water collection tank 7 causing a significant increase in humidity inside the temperature control cover 2, ensuring the humidity value inside the temperature control cover 2, improving the preservation effect on the tube seat, and the moisture in the water collection tank 7 flows into the water collection box 622 and can be reused, saving water resources and forming a water circulation system inside the temperature control cover 2.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
