Description

Technical Field

[0001] The invention relates to the technical field of glasses frame welding, in particular to a glasses frame brazing device. Background Art

[0002] Brazing is a welding process that connects the parent metal by melting the brazing filler metal. Its core feature is that the parent metal does not melt, and only relies on the wetting and capillary action of the brazing filler metal after melting to fill the joint gap and form a metallurgical bond. Brazing can efficiently connect different metals, so in the manufacture of eyeglass frames, it is also necessary to connect different frames by brazing. The traditional eyeglass frame brazing process usually includes three steps: workpiece clamping, brazing wire filling and heating welding: first, a special fixture is used to position and clamp the specific part of the frame, then the brazing wire is manually placed accurately between the butt joints of the two workpieces to be welded, and finally the brazing wire is centrally heated by the welding gun set on the top to melt it and achieve a firm connection between the workpieces after cooling and solidification; Although this process has been widely used in the industry, as the market's requirements for eyewear quality continue to increase, existing technologies have gradually exposed significant technical shortcomings; in the workpiece positioning link, due to the lack of high-precision automatic alignment mechanism, how to ensure that the left and right sets of glasses frames are symmetrically extruded on both sides of the soldering wire with micron-level accuracy to avoid welding misalignment or cold welding problems caused by position deviation has always been a technical bottleneck restricting process reliability; in addition, there are more prominent defects in the manual filling link: the operator needs to manually place the soldering wire in the narrow welding gap, which not only requires extremely high operating proficiency, but also makes it difficult to avoid the angle deviation of the soldering wire caused by manual operation. Once there is an angle between the soldering wire and the welding surface, it is very easy to form welding defects such as pores and lack of fusion during the cooling process, which significantly reduces the mechanical properties of the connection part; at the same time, the manual filling method also has problems such as low efficiency and high labor intensity, which is difficult to meet the needs of large-scale production, and it is urgent to achieve process upgrades through technological innovation.

The setting of the welding assembly 2 can melt the brazing wire 52 from the top side. At the same time, with the subsequent pneumatic drive performed by the pneumatic assembly 4, the precision of the brazing of the brazing wire 52 is further ensured, solving the problems of manual positioning and placement in existing brazing and relatively low precision in corresponding hot melting processing; In addition, through the setting of the auxiliary welding assembly 7 clamped on the guide rail 3, the heat conduction effect can be ensured by the contact clamping method of the auxiliary welding assembly 7, realizing the heat dissipation effect during hot melting welding on the auxiliary welding assembly 7. At the same time, the setting of the auxiliary welding assembly 7 can automatically eject the brazing wire 52 placed therein when the pneumatic assembly 4 moves horizontally, ensuring that the brazing wire 52 is always in a standard vertical state, and further ensuring the precision during subsequent hot melting brazing, solving the problem of poor precision in existing brazing; In addition, for this brazing device for spectacle frames, through the setting of the wire feeding assembly 5 and the wire cutting assembly 6, the brazing wire 52 can be horizontally fed, and the wire feeding assembly 5 cooperates with the downward drive of the wire cutting assembly 6 to cut off the brazing wire 52 of a corresponding length, realizing the effect of automatic and precise wire feeding.

[0022] Embodiment 3: As a preferred solution of the eyeglass frame brazing equipment of the present invention, the pneumatic assembly 4 includes a pressure cylinder 41 which is sleeved on the bottom end of the pressure frame 22 in the welding assembly 2 and installed on the inner wall of the frame 1, the bottom end of the pressure cylinder 41 is connected to an air pipe 42, the outer end of the air pipe 42 is connected to an air cylinder 43, the air cylinder 43 is installed on the guide rail 3, a piston column 44 is press-fitted on the inner side of the air cylinder 43, the outer end of the piston column 44 is connected to a slide seat 45 which is slidably sleeved on the guide rail 3, a pressure seat 46 is installed at the front end of the slide seat 45, the pressure seat 46 includes a lower horizontal plate and a spring-pressing sheet on the top side thereof, and the spring-pressing sheet is a horizontal L-shaped sheet; Among them, the pressing frame 22 is movably mounted in the pressing cylinder 41. When it is pressed down by the hydraulic cylinder group 21, the gas in the pressing cylinder 41 is squeezed and transported to the air cylinder 43 along the air pipe 42. When the amount of gas inside the air cylinder 43 increases, the piston column 44 therein is squeezed to move outward, and then the slide seat 45 is laterally pushed out.

When the brazing wire 52 placed on the top side is subjected to hot melting processing by the welding gun 23 in the welding component 2, the surrounding side of the auxiliary welding component 7 is heated and heated, and the heat is transmitted along the auxiliary welding component 7 to the wing seat 72, and is cooled by the fan seat 33 directly below, thereby ensuring the brazing effect from the side.

[0024] Example 5: In order to push the placed solder wire 52 upward from the middle of the auxiliary welding assembly 7, please refer to Figure 5 and Figure 6 The inner side of the welding seat 71 is provided with a built-in groove, in which a prying assembly 75 is provided, a ball groove 78 is provided at the top of the welding seat 71, a support groove 73 is provided in the middle of the welding seat 71, a clamping plate 76 is placed in the support groove 73, and a wire seat 77 for placing the soldering wire 52 on the top is installed on the top of the clamping plate 76; The branch groove 73 is provided to facilitate the vertical upward and downward movement of the clamping plate 76 therein, while the arc-shaped wire seat 77 is provided to facilitate the direct and stable placement of the solder wire 52 thereon, thereby ensuring the positioning effect of the solder wire 52 and simultaneously ensuring the accuracy and effect of subsequent hot-melt soldering.

[0025] The prying assembly 75 includes a sleeve column 755 installed in the built-in groove, a sleeve 752 is rotatably mounted in the sleeve column 755, a pressure ball 751 mounted in the ball groove 78 is connected to one side of the sleeve 752, a support rod 753 and a hinge joint 754 are connected to the other side of the sleeve 752, and the outer end of the support rod 753 is connected to the clamping plate 76 through the hinge joint 754; Among them, the prying component 75 structure is set up, in which the upper half of the pressure ball 751 is placed above the welding seat 71, and during the lateral movement of the pneumatic component 4, the pressure ball 751 is pushed down to the inner side of the welding seat 71. At the same time, the sleeve 752 and the sleeve column 755 are set up, which can pry the support rod 753 and the end of the hinge joint 754 up, and then drive the clamping plate 76, the wire seat 77 and the soldering wire 52 placed thereon to move up synchronously, so as to achieve the effect of ejecting the soldering wire 52. At the same time, the position of the soldering wire 52 is always constant to ensure the positioning effect.

[0026] Example 6: In order to realize the automatic wire feeding and corresponding reciprocating wire cutting of the wire feeding assembly 5, please refer to Figure 7 and Figure 8, the wire feeding assembly 5 is installed on the wire threading seat 51 at the rear side of the guide rail 3. A wire groove for sleeving the brazing wire 52 is formed on the top side of the wire threading seat 51. The wire feeding assembly 5 further includes a motor frame 53 installed on the frame 1. A driving motor 57 is installed on the outer side of the top of the motor frame 53. An auxiliary frame 54 is sleeved on the output shaft of the driving motor 57. Two sets of eccentric blocks 58 opposite in position are installed on the output shaft. An auxiliary roller 56 is arranged above the auxiliary frame 54, and the left side of the auxiliary frame 54 is connected to the auxiliary roller 56 through the auxiliary frame 54; Among them, the setting of the wire threading seat 51 facilitates the transmission and sleeving of the brazing wire 52 by using the wire groove therein, ensuring the accuracy of the initial wire feeding position of the brazing wire 52. The setting of the driving motor 57 can drive the driving roller 55 to rotate. With the setting of the auxiliary roller 56, it can move the brazing wire 52 clamped between them forward, achieving the effect of stable wire feeding. At the same time, the setting of the driving motor 57 can synchronously drive the eccentric block 58 to rotate.

[0027] The wire cutting assembly 6 includes a bracket 61 installed on the auxiliary welding assembly 7. A column groove is formed in the bracket 61. A through column 63 is sleeved in the column groove. A cutting knife 62 is connected to the bottom end of the through column 63. A spring rib column 64 connecting the bracket 61 and the cutting knife 62 is arranged on the outer side of the through column 63. And abutting columns 65 in contact with the eccentric blocks 58 in the wire feeding assembly 5 are arranged on the left and right parts of the top side of the cutting knife 62; Among them, the rotation of the eccentric block 58 driven by the driving motor 57 can continuously contact the abutting column 65 during its rotation, causing the cutting knife 62 to be forced to press down. During the pressing down process, the cutting knife 62 cuts off the brazing wire 52 at the bottom side. At the same time, the spring rib column 64 is continuously stretched during the downward movement of the cutting knife 62. Once the eccentric block 58 is separated from the abutting column 65, at this time, the spring rib column 64 pulls up the cutting knife 62 to make it return to its original position, so as to cooperate with the wire feeding assembly 5 for quantitative reciprocating wire cutting.

[0028] In addition, the frame 1 is a convex frame with openings at the top side and the ends. A welding frame in an L shape is installed on the top of the frame 1, and a welding assembly 2 is assembled on the top of the welding frame; Among them, the shape of the frame 1 and the setting of the welding frame thereon facilitate the installation of each component thereon, ensuring the stability of the overall structure.

[0029] The working principle and use process of the present invention are as follows: when the device is required to work, the brazing wire 52 is placed in the wire feeding assembly 5, and the driving motor 57 thereon drives the driving roller 55 to rotate, and realizes stable wire feeding of the brazing wire 52. At the same time, the corresponding rotation of the eccentric block 58 can squeeze the cutter 62 in the wire cutting assembly 6 to move downward, cut off the brazing wire 52 placed on the front side thereof, and realize stable wire feeding and wire cutting. When the hydraulic cylinder group 21 in the welding assembly 2 drives the pressing frame 22 and the welding gun 23 to move downward, the downward movement of the pressing frame 22 squeezes the airflow in the pressing cylinder 41, and the airflow is transported to the air cylinder 43 along the air pipe 42. When the amount of gas inside the air cylinder 43 increases, the piston column 44 therein is squeezed to move outward, thereby laterally ejecting the slide 45, and synchronously ejecting the glasses frame clamped in the pressing seat 46 on the front side of the slide 45. At the same time, the lateral displacement spacing of the left and right groups of glasses frames is exactly the same, which can The precision of subsequent brazing can be ensured. During the transverse movement of the pneumatic component 4, the plate squeezes the pressure ball 751 in the prying component 75, and synchronously pushes the pressure ball 751 down to the inner side of the welding seat 71. At the same time, the sleeve 752 and the sleeve column 755 can pry the support rod 753 and the end of the hinge joint 754 upward, thereby driving the clamping plate 76, the wire seat 77 and the brazing wire 52 placed thereon to move upward synchronously, so as to achieve the effect of ejecting the brazing wire 52 and placing it between the left and right groups of glasses frames. The welding gun 23 then sprays a flame flow to heat-melt the brazing wire 52, so as to achieve the brazing connection of the two groups of glasses frames. At the same time, the peripheral side of the auxiliary welding component 7 is heated up during brazing, and the heat is exported to the wing seat 72. Finally, the fan seat 33 drives the gas to circulate, so as to achieve air cooling and heat dissipation of the bottom side of the auxiliary welding component 7, so as to ensure the continuity and stability of brazing.
