Description
Technical Field
[0001] The present invention relates to the technical field of electronic manufacturing, in particular to a hot air hood structure for assembling electronic parts. Background Art
[0002] In the field of electronic manufacturing technology, the integration of electronic products continues to improve, the size of electronic components is becoming smaller and smaller, and the precision continues to rise. The assembly of electronic components requires a high degree of accuracy and reliability to ensure the normal operation of electronic products. In the process of assembling electronic components, the welding link is particularly important. Therefore, there is a special need for a hot air hood structure for assembling electronic components.
[0003] However, the traditional hot air hood structure generally has a relatively single nozzle at the hot air hood outlet. Due to the different shapes and sizes of electronic parts, the hot air hood with a single nozzle structure is difficult to uniformly heat parts of complex shapes, thereby affecting the quality of welding. Even if some hot air hood structures have the function of replacing nozzles, most of the nozzle replacement methods are relatively direct snap-on connections. Since the temperature of the hot air nozzle part is too high during connection, it is easy to cause burns to the user. This not only threatens the personal safety of the operator, but may also cause production interruptions due to operational errors or delays, causing economic losses and reduced production efficiency to electronic manufacturing companies. Summary of the Invention

Since the shapes and sizes of electronic components are different, the hot air hood with a single nozzle structure is difficult to uniformly heat parts of complex shapes, thereby affecting the quality of welding. Even if some hot air hood structures have the function of replacing the nozzle, most of the nozzle replacement methods are relatively direct snap-on connections. Since the temperature of the hot air nozzle part is too high during connection, it is easy to cause burns to the user. This not only threatens the personal safety of the operator, but may also cause production interruption due to operational errors or delays, causing economic losses and reduced production efficiency to electronic manufacturing companies.

[0009] Preferably, the inner size of the basic connecting head matches the outer size of the middle section small-aperture head, and the inner size of the middle section small-aperture head matches the outer ring size of the large shovel-shaped flat mouth, small round air nozzle and elbow air nozzle.
[0010] Preferably, the elastic sheet, the pressing block and the engaging block are provided in a group on both symmetrical sides of the middle section small aperture head, and the elastic sheet is rotatably connected to the middle section small aperture head through its own elasticity.
[0011] Preferably, the size of the engaging block matches the size of the first engaging hole, and a plurality of anti-slip grooves are provided on one side surface of the pressing block.
[0012] Preferably, the large shovel-shaped flat nozzle, small round nozzle and elbow nozzle are provided with pressing blocks and snap blocks identical to those of the middle section small-aperture head below, and can be snap-connected through the second snap-fit hole of the middle section small-aperture head.

The cylindrical groove on the surface of the adjustment knob facilitates the operation of finger force, and the display screen can intuitively display the current working status information, such as temperature value, wind speed gear, etc. Through the setting of the head-changing mechanism, when facing different electronic parts assembly tasks, if it is necessary to replace the nozzle of the hot air hood head, for the connection between the basic connecting head and the middle small-aperture head, the buttons on both sides of the middle small-aperture head can be pressed. The pressing block deforms the elastic sheet, and then the middle section small-aperture head is inserted from the base connecting head. After releasing the pressing block, the locking block is re-locked into the corresponding locking hole under the action of the elastic sheet to complete the installation of the middle section small-aperture head. When a large shovel-shaped flat nozzle, a small round nozzle or an elbow nozzle is to be used, the corresponding pressing block is pressed in the same manner, and then the large shovel-shaped flat nozzle, the small round nozzle or the elbow nozzle is inserted into the middle section small-aperture head to make the locking block reach the position of the corresponding locking hole, and then the pressing block is released, and the locking block is locked in the locking hole. This avoids contact when the nozzle is changed, which not only meets the diversity of the hot air hood outlet head, but also the setting of the pressing block avoids direct contact between the user and the hot air nozzle, which is not easy to cause burns to the user, reduces production interruptions caused by operating errors or delays, and improves the economic benefits and production efficiency of electronic manufacturing companies.

[0023] The head-changing mechanism 11 includes a basic connecting head 1101, a first engaging hole 1102, a middle section small-aperture head 1103, an elastic sheet 1104, a pressing block 1105, a engaging block 1106, a second engaging hole 1107, a large shovel-shaped flat mouth 1108, a small round air nozzle 1109 and an elbow air nozzle 1110. One side surface of the hot air hood head 8 is fixedly connected with the basic connecting head 1101, one side surface of the basic connecting head 1101 is provided with a first engaging hole 1102, the inner side surface of the basic connecting head 1101 is slidably connected with the middle section small-aperture head 1103, one side surface of the middle section small-aperture head 1103 is fixedly connected with the elastic sheet 1104, and one side surface of the elastic sheet 1104 is fixedly connected It is connected with a pressing block 1105, a clamping block 1106 is fixedly connected to one side surface of the elastic sheet 1104, a second clamping hole 1107 is provided on one side surface of the middle section small aperture head 1103, a large shovel-shaped flat mouth 1108 is slidably connected to the upper surface of the middle section small aperture head 1103, a small round air nozzle 1109 is slidably connected to the upper surface of the middle section small aperture head 1103, an elbow air nozzle 1110 is slidably connected to the upper surface of the middle section small aperture head 1103, and the basic connecting head 1101, the first clamping hole 1102, the middle section small aperture head 1103, the elastic sheet 1104, the pressing block 1105, the clamping block 1106, the second clamping hole 1107, the large shovel-shaped flat mouth 1108 , small round nozzle 1109 and elbow nozzle 1110 are set. When in use, if the nozzle of the hot air hood head 8 needs to be replaced, for the connection between the basic connecting head 1101 and the middle section small aperture head 1103, the pressing blocks 1105 on both sides of the middle section small aperture head 1103 can be pressed to deform the elastic sheet 1104, and then the middle section small aperture head 1103 can be inserted from the basic connecting head 1101. After loosening the pressing blocks 1105, the locking blocks 1106 are re-locked into the corresponding first locking holes 1102 under the action of the elastic sheet 1104, completing the installation of the middle section small aperture head 1103. When the nozzle is replaced, the user can press the pressing block 1105 in the same manner, and then the large shovel-shaped flat nozzle 1108, the small round nozzle 1109 or the elbow nozzle 1110 is inserted into the middle small-aperture head 1103, so that the locking block 1106 reaches the position corresponding to the second locking hole 1107, and then the pressing block 1105 is released. The locking block 1106 is locked in the locking hole, which avoids direct contact when the nozzle is replaced. It not only meets the diversity of the hot air hood outlet head, but also the setting of the pressing block 1105 avoids direct contact between the user and the hot air nozzle, which is not easy to cause burns to the user, reduces production interruptions caused by operating errors or delays, and improves the economic benefits and production efficiency of electronic manufacturing companies.
[0024] Furthermore, a cylindrical groove is provided on the surface of the adjusting knob 5, and eight groups are symmetrically arranged with the median perpendicular line of the adjusting knob 5. A group of heat dissipation holes 6 are respectively provided on the left and right side surfaces of the hot air hood body 4, and each group has four holes. Through the setting of the adjusting knob 5 and the heat dissipation holes 6, when in use, the user needs to adjust the temperature, wind speed and other parameters of the hot air by turning the adjusting knob. The design of the cylindrical groove can increase the friction between the finger and the knob, allowing the user to hold the knob and apply rotational force more easily and stably, which is convenient for operation. A group of heat dissipation holes is respectively provided on the left and right side surfaces of the hot air hood body, which can evenly dissipate heat from multiple positions, avoid local overheating, effectively reduce the temperature inside the hot air hood, and improve the stability and service life of the equipment.
[0025] Furthermore, the outer size of the protective net 9 is consistent with the outer size of the filter 10. The surface of the protective net 9 is rectangular air holes, while the surface of the filter 10 is circular air holes. Through the arrangement of the protective net 9 and the filter 10, when in use, the rectangular air holes on the surface of the protective net and the circular air holes on the surface of the filter cooperate with each other to form a double filtration system. The rectangular holes can initially block larger foreign matter, and the circular holes can further filter smaller impurities, thereby improving the filtering effect of the air entering the hot air hood, preventing dust and other impurities from entering the hot air hood and affecting its normal operation or damaging internal components.
[0026] Furthermore, the inner size of the basic connecting head 1101 is consistent with the outer size of the middle section small aperture head 1103, and the inner size of the middle section small aperture head 1103 is consistent with the outer circle size of the large shovel-shaped flat mouth 1108, the small round air nozzle 1109 and the elbow air nozzle 1110. Through the setting of the middle section small aperture head 1103, the large shovel-shaped flat mouth 1108, the small round air nozzle 1109 and the elbow air nozzle 1110, when in use, the hot air hood can be compatible with a variety of air nozzles of different shapes and functions, meeting the diverse requirements of different electronic parts assembly tasks for hot air outlet shapes and angles, and improving the versatility and applicability of the equipment.
[0027] Furthermore, a group of elastic sheets 1104, pressing blocks 1105 and snap blocks 1106 are arranged on both symmetrical sides of the middle section small-aperture head 1103. The elastic sheet 1104 is rotatably connected to the middle section small-aperture head 1103 through its own elasticity. Through the arrangement of the elastic sheet 1104, pressing blocks 1105 and snap blocks 1106, the risk of burns caused by accidental contact with high-temperature components is reduced during use, and the safety of operation is improved. Especially in the case of long-term use or frequent replacement of nozzles, the personal safety of users can be effectively protected.
[0028] Furthermore, the size of the locking block 1106 is consistent with the size of the first locking hole 1102, and a plurality of anti-slip grooves are provided on one side surface of the pressing block 1105. Through the setting of the pressing block 1105, the anti-slip grooves increase the friction between the fingers and the pressing block during use, and the operator can apply pressure more easily and stably, avoiding inadequate pressing or operational errors due to finger slippage, making the head changing process smoother.
[0029] Furthermore, a pressing block 1105 and a locking block 1106 identical to the middle section small aperture head 1103 are provided below the large shovel-shaped flat mouth 1108, the small round air nozzle 1109 and the elbow air nozzle 1110, and can be locked and connected through the second locking hole 1107 of the middle section small aperture head 1103. Through the setting of the second locking hole 1107, a tight locking connection can be achieved during use, ensuring that the air nozzle will not loosen or fall off due to the impact of hot air or slight external force collision during use, ensuring the stability of the connection between the air nozzle and the middle section small aperture head 1103, thereby improving the stability and reliability of the hot air hood during operation.
[0030] Furthermore, the air outlet of the large shovel-shaped flat nozzle 1108 is square, the air outlet of the small round nozzle 1109 is round, and the air outlet of the elbow nozzle 1110 is a smooth arc, and the curvature of the arc is gradual. Through the arrangement of the large shovel-shaped flat nozzle 1108, the small round nozzle 1109 and the elbow nozzle 1110, when in use, the large shovel-shaped flat nozzle 1108 with a square air outlet can provide a larger air outlet area in the assembly of electronic parts, so that the hot air can more widely cover the surface of the electronic parts that need to be heated, thereby achieving uniform heating over a large area. The small round nozzle 1109 with a circular air outlet can concentrate the hot air in a smaller circular area, thereby achieving local precise heating, and the smooth and gradually changing curvature arc air outlet design of the elbow nozzle 1110 enables it to flexibly provide hot air at different angles and directions.
[0031] Working principle: This is a hot air hood structure for assembling electronic parts. When in use, first, the user connects the hot air hood to a suitable power socket through the power cord 3 to ensure a stable power supply. Then, hold the handle 1 and turn on the hot air hood by pressing the switch 2. At this time, the heating element in the hot air hood body 4 starts to work and generate hot air. The user can adjust the temperature, wind speed and other parameters of the hot air according to actual needs by turning the adjustment knob 5. The cylindrical groove on the surface of the adjustment knob 5 is convenient for finger force operation, and the display screen 7 can intuitively display the current working status information, such as temperature value, wind speed gear, etc. Through the setting of the head changing mechanism 11, when facing different electronic parts assembly tasks, if it is necessary to replace the nozzle of the hot air hood head 8, for the connection between the basic connecting head 1101 and the middle small-aperture head 1103, the pressing blocks 1105 on both sides of the middle small-aperture head 1103 can be pressed to deform the elastic sheet 1104, and then the middle small-aperture head 1103 can be removed from the basic connecting head 110 1, after releasing the pressing block 1105, the locking block 1106 is re-locked into the corresponding first locking hole 1102 under the action of the elastic piece 1104, completing the installation of the middle section small aperture head 1103. When the large shovel-shaped flat nozzle 1108, the small round nozzle 1109 or the elbow nozzle 1110 is to be used, the corresponding pressing block 1105 is pressed in the same manner, and then the large shovel-shaped flat nozzle 1108, the small round nozzle 1109 or the elbow nozzle 1110 is inserted into the middle section small aperture head 1103 to make the locking Block 1106 reaches the position corresponding to the second engaging hole 1107, and then the pressing block 1105 is released, and the engaging block 1106 is engaged in the engaging hole, thereby avoiding direct contact when changing the nozzle head. It not only meets the diversity of the hot air hood outlet head, but also the setting of the pressing block 1105 avoids direct contact between the user and the hot air nozzle, which is not easy to cause burns to the user, reduces production interruptions caused by operational errors or delays, and improves the economic benefits and production efficiency of electronic manufacturing companies.
