Abstract
Description
Technical Field
[0001] The invention relates to a welding process, in particular to a patch welding process. Background Art
[0002] There are many large spacings on the market now, but long plastic parts are prone to deformation, unevenness, bending, and flatness exceeding 0.3mm after production. It is difficult to meet the flatness requirements. How to solve the flatness requirements is the technical problem we need to solve now. Summary of the invention
[0003] In view of the deficiencies of the existing technology, the present invention provides a patch welding process.
[0004] In order to achieve the above object, the technical solution adopted by the present invention is: a patch welding process, the process comprising the following steps:
[0005] (1) Making the assembly to be processed
[0006] Step 1: Install the first copper part into the main body of the plastic part to obtain an assembly, and expose the welding part;
[0007] Step 2: Apply solder paste on the welding surface of the first copper piece in the assembly in step 1 to obtain an assembly to be processed;
[0008] (2) Preparation of monomers to be processed
[0009] Step 3: Place the second copper piece with the bend into the fixture to obtain a single body to be processed, and expose the welding part;
[0010] (3) Welding process
[0011] Step 4: Place the assembly to be processed in step 2 on a conveying mechanism capable of horizontal reciprocating movement, and install it on its tooling;
[0012] Step 5: Push the assembly to be processed on the tooling in step 4 to the fixture position, and make the first copper piece in the assembly to be processed in step 2 correspond to the second copper piece in the single body to be processed in step 3;
[0013] Step 6: The welding gun above the fixture moves downward and welds the first copper piece and the second copper piece corresponding to step 5 to obtain a finished product.
[0014] The conveying mechanism in step 4 includes a guide rail for reciprocating motion of the tooling, and the guide rail is provided with a first protrusion and a second protrusion for limiting the stroke of the tooling. The tooling has an initial position state and a welding position state, and the initial position state and the welding position state are converted into each other through the mutual cooperation of the tooling, the first protrusion and the second protrusion.
[0015] The conveying mechanism includes a proximity switch for opening and closing the welding gun in step 6. When the tooling is in the welding position, the welding gun moves downward through the cooperation of the proximity switch to achieve the welding work of the first copper part and the second copper part.
[0016] Beneficial effects of the present invention: the present invention fixes the bent copper part by a clamp, pushes another copper part to the front copper part by a horizontal conveying mechanism, and then uses a welding gun to perform welding, which changes the previous vertical welding process and greatly improves the accuracy of the process. When welded according to this process, the product will be relatively flat and will not be deformed with the bending of the plastic part. The flatness of the copper part is redefined and will not be affected by the deformation of the plastic part. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-Figure 3 As shown, a patch welding process includes the following steps:
[0021] (1) Making the assembly to be processed
[0022] Step 1: Install the first copper piece 1 into the plastic body 2 to obtain an assembly 3, and expose the welding portion. The drawings of this application show the plastic body 2 with three groups of first copper pieces 1 and second copper pieces 4 welded at the same time. No matter how many groups of copper pieces there are, they all fall within the protection scope of this application;
[0023] Step 2: Apply solder paste on the welding surface of the first copper piece 1 in the assembly 3 of step 1 to obtain the assembly to be processed, and the solder paste used is resistant to high temperatures above 200 degrees Celsius;
[0024] (2) Preparation of monomers to be processed
[0025] Step 3: Place the second copper piece 4 with a bend into the fixture 5 to obtain a single body 6 to be processed, and expose the welding part;
[0026] (3) Welding process
[0027] Step 4: Place the assembly to be processed in step 2 on a conveying mechanism 7 capable of transverse reciprocating movement, and install it on its tooling 8. The conveying mechanism 7 and the fixture 5 can be installed together on the work surface 14;
[0028] Step 5: Push the assembly to be processed on the tooling 8 in step 4 to the position of the fixture 5, and make the first copper piece 1 in the assembly to be processed in step 2 and the second copper piece 4 in the single body to be processed 6 in step 3 correspond to each other;
[0029] Step 6: The welding gun 9 above the fixture 5 moves downward and welds the first copper piece 1 and the second copper piece 4 corresponding to step 5 to obtain a finished product. After welding, the welding gun 9 returns to its original position and then takes out the finished product.
[0030] The conveying mechanism 7 in step 4 includes a guide rail 10 for reciprocating motion of the tooling 8. The guide rail 10 is provided with a first protrusion 11 and a second protrusion 12 for limiting the stroke of the tooling 8. The tooling 8 has an initial position state and a welding position state. The initial position state and the welding position state are converted to each other through the mutual cooperation of the tooling 8, the first protrusion 11 and the second protrusion 12. The first protrusion 11 is the initial position of the guide rail 10, and the second protrusion 12 is the welding position of the guide rail 10.
[0031] The conveying mechanism 7 includes a proximity switch 13 for opening and closing the welding gun 9 in step 6. When the tooling 8 is in the welding position, the welding gun 9 moves downward through the cooperation of the proximity switch 13 to achieve the welding work of the first copper part 1 and the second copper part 4. The proximity switch 13 adopts a metal proximity switch. When the tooling 8 delivers the first copper part 1 to the second bump 12, the proximity switch 13 senses and controls the welding gun 9 to weld the first copper part 1 and the second copper part 4, which is more automated.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, simple changes and substitutions by ordinary technicians in the field are within the protection scope of the present invention.
