The brazing flux may fall off during the operation of the radiator, affecting the use of the radiator, and also affecting the cleanliness and corrosion resistance of the radiator. There is a problem that the brazing flux is easily sprayed onto the non-brazing area of the part. Utility Model Content

[0033] See Figure 1 and Figure 2 The utility model provides a spray shielding device, including a tray 1, a baffle 2 and a limiting card strip 3. The tray 1 is provided with a accommodating groove 11 for accommodating parts; the baffle 2 includes a mounting portion 21 and a shielding portion 22. The shielding portion 22 is arranged on the side of the mounting portion 21 away from the tray 1 for shielding parts; the limiting card strip 3 is arranged on the tray 1, and the mounting portion 21 is detachably connected to the limiting card strip 3.

[0034] In this embodiment, the tray 1 is a rectangular plate-like structure, the length directions of the mounting portion 21 and the shielding portion 22 are parallel, and both are long strip structures, and the cross-sectional area of the shielding portion 22 is larger than the cross-sectional area of the mounting portion 21; there are multiple baffles 2, and the multiple baffles 2 are detachably connected to the limiting card strips 3, and the multiple baffles 2 are arranged in parallel; the limiting card strips 3 are arranged at the edge of the tray 1, and the length direction of the limiting card strips 3 is perpendicular to the length direction of the baffles 2.

[0035] In this way, placing the parts in the accommodating groove 11 can limit the position of the parts on the pallet 1, connect the mounting portion 21 with the limiting clip 3, fix the positions of the mounting portion 21 and the shielding portion 22, determine the shielding area, and thus make the shielding portion 22 shield the non-soldering area of the parts, so that during the spraying process, the flux can be prevented from being sprayed to the non-soldering area, and the flux can be sprayed only to the soldering area, thereby reducing the flux residue on the surface of the parts and improving the cleanliness and corrosion resistance of the parts; by providing a detachable barrier bar 2, it is convenient for the staff to clean and maintain the barrier bar 2 to ensure the shielding effect.

[0036] It can be understood that the shape of the shielding portion 22 can be flexibly adjusted according to the non-soldering area of the part, and the shielding portion 22 can be fixedly connected to the mounting portion 21, or can be detachably connected to the mounting portion 21. In this embodiment, the shielding portion 22 is detachably connected to the mounting portion 21, which facilitates the assembly of mounting portions 21 of different shapes on the shielding portion 22 to adapt to non-soldering areas of different shapes, thereby improving the flexibility of the spray shielding device; the mounting portion 21 can also be directly installed on the tray 1, which will not be listed in detail here.

[0037] See Figure 2In some embodiments, the tray 1 is provided with a mounting groove 12 for accommodating the position-limiting clip 3, so that the tray 1 is engaged with the position-limiting clip 3 and the mounting groove 12 is connected to the accommodating groove 11. In this embodiment, the mounting groove 12 is provided on the top surface of the tray 1, and the shape of the mounting groove 12 is adapted to the shape of the position-limiting clip 3, and the height of the mounting groove 12 is less than the height of the position-limiting clip 3.

[0038] In this way, the limit strip 3 is clamped in the installation groove 12, which can limit the relative position of the limit strip 3 and the pallet 1, facilitate the flexible assembly of the limit strip 3, and clean and maintain it, improve the stability of the baffle 2 on the pallet 1, and avoid the baffle 2 on the pallet 1 being offset during part processing, resulting in the shielding portion 22 being unable to effectively shield the non-soldering area of the part, improve the shielding stability during the process of spraying solder on the part, and reduce the solder residue in the non-soldering area of the part surface.

[0039] It is understandable that the installation groove 12 may also be disconnected from the accommodating groove 11, so that the limit card strip 3 can be assembled to the pallet 1; the connection method between the limit card strip 3 and the pallet 1 is not limited to clamping, and it can also be detachably connected to the pallet 1 through bolts, or it can be fixedly connected. In this embodiment, the limit card strip 3 is clamped with the pallet 1, which can enable the pallet 1 to limit the limit card strip 3 while facilitating the loading and unloading of the limit card strip 3, thereby facilitating the maintenance and cleaning of the limit card strip 3, and avoiding the accumulation of flux on the surface of the limit card strip 3 and affecting the limiting effect of the limit card strip 3 on the baffle 2.

[0040] See Figure 2 and Figure 3 In some embodiments, the mounting groove 12 is set through the side wall of the tray 1, and the length of the limiting card strip 3 is greater than the length of the side of the tray 1 connected to the limiting card strip 3.

[0041] In this way, the limiting card strip 3 can be further stably connected to the tray 1, avoiding the limiting card strip 3 from shaking or shifting and thus affecting the limiting effect; the installation groove 12 passes through the side wall of the tray 1, which can make the flux flow to the outside through the installation groove 12 during the spraying process, reducing the flux residue on the surface of the limiting card strip 3 and inside the installation groove 12, and improving the cleanliness of the spray shielding device during the spraying process and the stability of the parts shielding and limiting.

[0042] It can be understood that the length of the limit card strip 3 can also be equal to or less than the length of the side of the tray 1 connected to the limit card strip 3. In this embodiment, the length of the limit card strip 3 is greater than the length of the side of the tray 1 connected to the limit card strip 3. This is to allow the limit card strip 3 to accommodate a larger number of baffles 2, and the flux can easily flow to the outside through the installation groove 12, thereby facilitating the maintenance of the limit card strip 3 and the baffle 2.

[0043] See Figure 3 and Figure 4In some embodiments, a limiting groove 31 for accommodating the mounting portion 21 is formed on a side of the limiting clip 3 facing away from the tray 1 so that the limiting clip 3 is engaged with the mounting portion 21 .

[0044] In this embodiment, the limiting grooves 31 are evenly spaced along the length direction of the limiting clip 3 , and the width of the limiting grooves 31 matches the width of the mounting portion 21 .

[0045] In this way, the mounting portion 21 is snapped into the limiting groove 31, which can limit the position of the blocking bar 2 on the limiting clip 3, so that the blocking bar 2 can stably block the non-soldering area of the part and limit the position of the part on the tray 1, thereby improving the stability of the shielding portion 22 in shielding the non-soldering area of the part during spraying; at the same time, the mounting portion 21 is snapped into the limiting clip 3, which can facilitate the removal of the mounting portion 21 from the limiting clip 3 and cleaning and maintenance. The flux remaining on the surface of the mounting portion 21 can also flow into the mounting groove 12 through the limiting groove 31, reducing the flux residue on the surface of the mounting portion 21; a variety of limiting clips 3 can be designed according to the specifications of the parts, so that the spacing of the limiting grooves 31 can be flexibly adjusted according to the specifications of the parts. By replacing the corresponding limiting clips 3, the spacing of the mounting portion 21 can be adjusted according to the specifications of the parts, thereby improving the flexibility of the spray shielding device.

[0046] It is understandable that the limit clip 3 can also be detachably connected to the mounting portion 21 by bolts, or the limit clip 3 can also be fixedly connected to the mounting portion 21. The specific connection method between the limit clip 3 and the mounting portion 21 can be flexibly adjusted according to actual needs, and will not be listed in detail here.

[0047] See Figure 5-Figure 7 In some embodiments, two limit clips 3 are provided, one on each side of the tray 1, and the two ends of the mounting portion 21 are detachably connected to the two limit clips 3. In this embodiment, the two limit clips 3 are arranged in parallel, and the two ends of the mounting portion 21 are respectively engaged with the two limit clips 3.

[0048] In this way, the two limiting clips 3 can limit the two ends of the mounting portion 21, thereby limiting the position of the blocking bar 2 and preventing the mounting portion 21 or the shielding portion 22 from being offset, so that the shielding portion 22 can stably shield the non-brazing area of the part during the spraying process, making it difficult for the brazing flux to be sprayed to the non-brazing area, thereby improving the brazing flux spraying effect and reducing the brazing flux residue on the surface of the part.

[0049] It can be understood that one limit strip 3 can also be provided, and one limit strip 3 is provided on one side of the pallet 1. The end of the mounting portion 21 facing away from the limit strip 3 can be overlapped on the pallet 1, and can also be detachably connected to the pallet 1 by bolts. The number of limit strips 3 can be flexibly adjusted according to actual needs, and it is sufficient to limit the position of the mounting portion 21. No more examples will be given here.

[0050] See Figure 6 and Figure 7 In some embodiments, the spray shielding device further includes a reinforcement member 4, which is disposed at the edge of the tray 1. The reinforcement member 4 is a reinforcing plate, which is disposed around the edge of the tray 1 and is fixedly connected to the tray 1. Furthermore, the reinforcing plate is integrally formed with the tray 1, and both the tray 1 and the reinforcement plate are made of stainless steel.

[0051] It should be noted that the parts need to be placed in a high-temperature environment during the process of spraying the brazing flux, and the tray 1 is prone to deformation. The reinforcing plate and the tray 1 need to be subjected to high-temperature annealing treatment before being put into use to prevent the tray 1 from deforming in a high-temperature environment.

[0052] In this way, the reinforcement 4 can further strengthen the structural strength of the pallet 1, prevent the pallet 1 from deforming in a high temperature environment and affecting the support of the parts, and prevent the limit strip 3 and the mounting portion 21 from offsetting after the pallet 1 is deformed, thereby improving the shielding stability of the shielding portion 22 on the non-soldering area of the parts, reducing the flux residue in the non-soldering area of the parts, and improving the cleanliness and corrosion resistance of the part surface.

[0053] It can be understood that the reinforcement 4 can also be detachably connected to the pallet 1. In this embodiment, the reinforcement 4 and the pallet 1 are formed as one piece, and its purpose is to further enhance the connection strength between the reinforcement 4 and the pallet 1; the materials of the reinforcement 4 and the pallet 1 can also be other fire-resistant metal materials, such as aluminum alloy materials, galvanized steel materials, etc., which are not listed in detail here.

[0054] See Figure 7 In some embodiments, the reinforcement member 4 includes a first portion 41 and a second portion 42. The first portion 41 is connected to the tray 1, and the second portion 42 is arranged at an angle to the first portion 41. In this embodiment, the first portion 41 is arranged horizontally, and the second portion 42 extends vertically downward on a side away from the first portion 41. That is, the angle between the first portion 41 and the second portion 42 is 90°, and the second portion 42 is arranged parallel to the side wall of the tray 1.

[0055] In this way, setting the first part 41 and the second part 42 perpendicular to each other can further enhance the structural strength of the pallet 1, making it less likely to deform in a high temperature environment, and making the relative positions of the limit bar 3 and the baffle 2 to the pallet 1 relatively fixed, thereby avoiding the displacement of the limit bar 3 and the baffle 2 after the pallet 1 is deformed, improving the shielding stability of the shielding part 22 for the non-brazing area of the part, and making it difficult for the brazing agent to be sprayed onto the surface of the part, thereby improving the cleanliness and corrosion resistance of the part.

[0056] It can be understood that the first part 41 and the second part 42 can also be set at an acute angle or an obtuse angle. In this embodiment, the first part 41 and the second part 42 are set vertically. The purpose is to improve the structural strength of the pallet 1 while reducing the space occupied by the reinforcement 4, which is convenient for use and storage; the side of the second part 42 away from the first part 41 can also extend vertically upward. In this embodiment, the second part 42 extends vertically downward, which can save the space occupied by the spray shielding device in the vertical direction.

[0057] See Figure 1 In some embodiments, the top surface of the first portion 41 of the reinforcement member 4 is flush with the top surface of the tray 1. By providing the first portion 41, the structural strength of the tray 1 can be enhanced. The top surface of the first portion 41 is flush with the top surface of the tray 1, which facilitates cleaning of the flux on the surface of the tray 1 and the reinforcement member 4.

[0058] It is understandable that the first portion 41 can also be set on the side wall of the tray 1. The setting position of the first portion 41 can be flexibly adjusted according to actual needs, which will not be described in detail here. In this embodiment, the top surface of the first portion 41 of the reinforcement 4 is flush with the top surface of the tray 1 for ease of processing.

[0059] See Figure 3 and Figure 5 In some embodiments, the barrier strip 2 further includes a connector 23, through which the mounting portion 21 and the shielding portion 22 are detachably connected. In this embodiment, the connector 23 is a bolt, and a plurality of bolts are provided along the length of the mounting portion 21. The mounting portion 21 has a hole (not shown) on the side facing the shielding portion 22 for the bolts to extend into, and the shielding portion 22 has a countersunk hole (not shown) for the bolts to extend into.

[0060] In this way, the shielding part 22 is assembled to the mounting part 21 through the connecting part 23, which can limit the position of the shielding part 22 on the mounting part 21, so that the shielding part 22 can stably shield the non-soldering area of the part. By assembling shielding parts 22 of different shapes to the mounting part 21, non-soldering areas of different shapes can be shielded, thereby improving the shielding flexibility.

[0061] It can be understood that a plug block may be fixedly provided on the side of the shielding portion 22 facing the mounting portion 21, and a slot may be provided on the side of the mounting portion 21 facing the shielding portion 22 corresponding to the plug block to enable the shielding portion 22 to be plugged into the mounting portion 21, or the mounting portion 21 may be fixedly connected to the shielding portion 22. In this embodiment, the mounting portion 21 and the shielding portion 22 are connected by bolts, which can facilitate the loading and unloading of the shielding portion 22 and make the position of the shielding portion 22 on the mounting portion 21 relatively fixed, thereby reducing the offset of the shielding portion 22.

[0062] See Figure 1In some embodiments, a through hole 5 is provided on the bottom surface of the tray 1 to reduce the residual flux on the tray 1. In this embodiment, a plurality of through holes 5 are provided, and the plurality of through holes 5 are evenly provided on the bottom surface of the tray 1. Furthermore, the through holes 5 are circular holes.

[0063] In this way, excess flux during the spraying process can flow to the outside through the through hole 5, avoiding excessive flux remaining in the tray 1 and affecting the spraying effect on the surface of the part. In addition, the through hole 5 can reduce the weight of the tray 1, making it easier for staff to carry and use it.

[0064] It is understandable that the shape of the through hole 5 is not limited to a circular hole, and can also be a square hole, a triangular hole, a special-shaped hole, etc. The specific shape of the through hole 5 can be adjusted according to actual needs, and no further examples are given here.

[0065] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
