Description

Air outlet plate structure of reflow soldering equipment

Technical Field

The utility model relates to a reflow soldering equipment technical field, more specifically says, it relates to an air-out plate structure of reflow soldering equipment.

Background

In the production process of the circuit board, the surface mounting technology is adopted for carrying out surface mounting assembly on each surface mounting element. Firstly, scraping soldering paste on pinholes and welding positions on a PCB by using a printer; then, the surface mount is switched and pressed to the corresponding welding position of the PCB by a surface mount machine to be attached to the soldering paste; and finally, the PCB attached with the element is sent into reflow soldering equipment for soldering, in the soldering process of the existing reflow soldering equipment, the soldering paste can generate oil stains, so that the oil stains can flow out of the air outlet hole in the ventilating plate of the reflow soldering equipment along with the flowing of gas and accumulate on the back of the ventilating plate, the oil stains can easily flow out of the air outlet hole and fall onto a product below the ventilating plate, the product is poor, and in order to avoid the problems, a user needs to frequently maintain and clean the air outlet plate.

In view of the above, the present invention has been made by the designers for solving the above problems, and the present invention is developed and designed by actively researching and improving the present invention.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a reflow soldering equipment's play aerofoil structure can prolong maintenance scavenging period.

To achieve the above object, the solution of the present invention is:

the utility model provides an air-out plate structure of reflow soldering equipment, the back of air-out plate is equipped with the recess, the recess encircles the exhaust vent setting of air-out plate, the interval is equipped with a plurality of exhaust vents on the air-out plate.

The air outlets are uniformly arranged at intervals.

The air outlet hole forms a hollow cylinder flow passage.

The top wall surface of the air outlet hole is flush with the edge of the air outlet plate.

After the technical scheme is adopted, the utility model discloses a structural design that sets up the recess at the back that goes out the aerofoil, thereby have the utility model discloses a reflow soldering equipment is in welding process, the produced greasy dirt of soldering paste can be gathered in flowing to the recess via the air-out hole, the recess provides storage space for the greasy dirt, lets the user maintain the washing again after the recess is more or less long-pending full greasy dirt, need not frequent maintenance again and washs the aerofoil, has prolonged maintenance purge time.

Detailed Description

To achieve the above objects and advantages, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Please refer to fig. 1 to 3, the present invention discloses an air outlet plate structure of reflow soldering equipment, the back of the air outlet plate 2 is provided with a groove 21, the groove 21 surrounds the air outlet 22 of the air outlet plate 2, and a plurality of air outlets 22 are arranged on the air outlet plate 2 at intervals.

Therefore, the utility model discloses a set up the structural design of recess 21 at the back that goes out aerofoil 2, thereby have the utility model discloses a reflow soldering equipment 1 is in welding process, the produced greasy dirt of soldering paste can gather in flowing to recess 21 via exhaust vent 22, recess 21 provides storage space for the greasy dirt, lets the user can wait that recess 21 maintains again after more than the long-pending greasy dirt, need not frequent maintenance again and washs aerofoil 2, has prolonged the maintenance scavenging period.

Further, in order to facilitate uniform formation of the air outlet holes 22, the air outlet holes 22 may be uniformly spaced.

Furthermore, the top wall surface 221 of the air outlet 22 is flush with the edge 23 of the air outlet plate 2, thereby facilitating the manufacture of the present invention.

Further, the air outlet 22 may form a hollow cylindrical flow passage for facilitating the flow of air, but not limited thereto, the air outlet 22 may also form a flow passage with other shapes.

Please refer to fig. 2, the utility model discloses a reflow soldering equipment's play aerofoil structure is when using, the front that goes out aerofoil 2 sets up towards PCB board 3, it sets firmly in reflow soldering equipment 1's air outlet 11's below to go out aerofoil 2, it is located PCB board 3's top to go out aerofoil 2, reflow soldering equipment 1 can be located to PCB board 3.

The technical content and technical features of the present invention have been disclosed as above, and the present invention is not limited to the above-mentioned components, and those skilled in the art may make various replacements and modifications based on the disclosure of the present invention without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should not be limited to the embodiments disclosed, but should include various alternatives and modifications without departing from the invention, and be covered by the claims.
