Description

Technical Field

[0001] The invention relates to the technical field of welding of honeycomb nets of air purifiers, and in particular to a welding device for honeycomb nets of air purifiers. Background Art

[0002] Brazing refers to a welding method in which the solder and the workpiece are heated to the melting temperature of the solder at the same time, and the gap between the solid workpieces is filled with liquid solder to connect the metals. Brazing has small deformation and smooth and beautiful joints, and is suitable for welding precise and complex components made of different materials, such as honeycomb structure plates, turbine blades, carbide tools and printed circuit boards.

[0003] The honeycomb mesh is an important component of the air purifier. It kills harmful bacteria in the air by forming a high-voltage electric field, and also has the function of absorbing small particles of dust and impurities in the air.

[0004] In the prior art, the welding of honeycomb mesh made of galvanized thin plates usually adopts conventional resistance spot welding to fix the connection, and manual spot welding is required for the welding points. This method has high labor intensity. Since the mesh diameter of the honeycomb mesh is not large, if the mesh is reduced, the spot welding electrode cannot penetrate into the mesh to weld, resulting in low welding strength of the honeycomb mesh, which is easy to desolder during use.

[0005] The prior art also includes equipment for welding honeycomb meshes by brazing. Although such equipment can solve the welding process of honeycomb meshes with small apertures, it can only adapt to the welding work of honeycomb meshes with fixed specifications. When the model of the honeycomb mesh changes, different welding clamping devices are required to clamp the galvanized sheet. The adaptability is poor and the application effect is not good. There is no welding bearing device that can adapt to honeycomb meshes of most types and apertures.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The welding mold can neatly install several stamped galvanized sheets in the shape of a honeycomb mesh, which is convenient for subsequent welding operations. The adjustable clamping frame can achieve autonomous adjustment. The bottom plate carries the stamped galvanized sheet on top. The adjustable clamping frame can change the installation size according to demand, so as to adapt to the production of honeycomb meshes of different sizes and models.

[0021] 2. The metal clamp can be used to clamp the position where two stamped galvanized sheets need to be welded, and the adjacent parallel fitting surfaces of the two stamped galvanized sheets can be tightly fitted, so that the stamped galvanized sheets can be stably clamped when the solder melts during the brazing process, thereby improving the welding effect. The clamp position adjustment component can adjust the position of the metal clamp according to the aperture formed by the honeycomb mesh and the size of the honeycomb mesh. While clamping the stamped galvanized sheets, the metal clamp can also ensure that several stamped galvanized sheets are tightly attached to the bottom plate, so that the heights of several stamped galvanized sheets remain consistent, thereby coping with the production process of honeycomb meshes with different apertures.

[0022] 3. Through the corresponding first vertical plate and second vertical plate, a baffle is formed to limit one side of the honeycomb net, and can be extended or shortened along the length direction without affecting the limiting function, so as to match the installation of honeycomb nets of different sizes. The limit frame is adjusted horizontally and vertically respectively through two sets of spacing adjustment components, so as to ensure the accuracy of the limit frame adjustment.

[0023] 4. The position of the first vertical plate can be limited by the limiting connecting plate and the horizontal limiting rod, so that it is always on the same horizontal plane as the rectangular limiting plate, ensuring that the limiting frame always remains horizontal when expanding or contracting, thereby ensuring the accuracy of the adjustment of the adjustable clamping frame.

[0024] 5. The threaded transmission sleeve installed on the rectangular limit plate is used for threaded transmission to realize the displacement of the first threaded rod in the horizontal position, thereby pushing the first vertical plate and the second vertical plate in the group to move forward or backward synchronously to realize the adjustment function, and the locking bolt is locked on the threaded transmission sleeve to ensure that the subsequent adjustable clamping frame can stably clamp the honeycomb mesh during movement and welding operations.

[0025] 6. The two parallel surfaces of the two stamped galvanized sheets are clamped in the clamping groove through the clamping groove. During the brazing process, the two parallel surfaces are always kept in close contact with each other, so that the solder can be evenly distributed in the weld during welding, improving the welding effect. The auxiliary clamping chamfer makes it easier to insert the two parallel surfaces into the clamping groove when the metal clamp is lowered.

[0026] 7. The first limit rod can drive the two sliding seats installed at both ends to move synchronously, and the movement of the second limit rod can drive several metal clamps located on the same side of the stamped galvanized sheet along the length direction to move synchronously. When clamping the honeycomb net, the present application only needs to clamp the honeycomb net at the fitting parts of several adjacent parallel fitting surfaces at both ends of the stamped galvanized sheet along the length direction, so as to complete the precise clamping function of the honeycomb net.

[0044] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] like Figure 1-15 As shown:

[0046] A honeycomb mesh welding device for an air purifier includes a stamped galvanized sheet 1, wherein the length direction of the stamped galvanized sheet 1 is horizontal, and the width direction of the stamped galvanized sheet 1 is longitudinal. A plurality of stamped galvanized sheets 1 are closely fitted in sequence along the longitudinal direction to form a honeycomb mesh. The stamped galvanized sheet 1 is composed of a plurality of parallel fitting surfaces 1a and inclined ladder surfaces 1b which are connected in sequence at intervals. The device also includes a welding mold 2, a clamping device 3 and a compaction driving mechanism 4. The welding mold 2 includes a bottom plate 2a, an adjustable clamping frame 2b, a spacing adjustment component 2c and a connecting component 2d. The bottom plate 2a is horizontally arranged in the welding device, a rectangular limiting plate 2a1 is arranged at the top of the bottom plate 2a, the adjustable clamping frame 2b is arranged in the rectangular limiting plate 2a1, the spacing adjustment component 2c is installed on the bottom plate 2a, the output end of the spacing adjustment component 2c is transmission-connected to the adjustable clamping frame 2b, the connecting component 2d is arranged on the bottom plate 2a, and the clamping device 3 and the compaction driving mechanism 4 are provided. The welding mold 2 includes a bottom plate 2a, an adjustable clamping frame 2b, a spacing adjustment component 2c and a connecting component 2d. The tightening device 3 includes a lower pressing plate 3a, a brazing auxiliary clamping device and a chuck position adjustment component 3d. The lower pressing plate 3a is connected to the base plate 2a through a connecting component 2d. The lower pressing plate 3a is located directly above the adjustable clamping frame 2b. The brazing auxiliary clamping device is provided with two groups. The two groups of brazing auxiliary clamping devices are respectively arranged at both ends of the stamped galvanized sheet 1 along the length direction. The brazing auxiliary clamping device includes a plurality of metal chucks 3c. The plurality of metal chucks 3c are correspondingly arranged between every two stamped galvanized sheets 1. The metal chucks 3c can be horizontally slidably arranged directly below the lower pressing plate 3a. The metal chucks 3c are transmission-connected to the lower pressing plate 3a. The chuck position adjustment component 3d is installed on the side wall of the lower pressing plate 3a. The chuck position adjustment component 3d is transmission-connected to the metal chucks 3c. The compaction drive mechanism 4 is installed on the welding equipment. The output end of the compaction drive mechanism 4 is transmission-connected to the lower pressing plate 3a.

[0047] Based on the above embodiment, the problem of how to realize the welding operation of the honeycomb mesh of the air purifier by brazing is solved, and the brazing welding equipment can adapt to the production of honeycomb meshes of different apertures and models. Through the welding mold 2, several stamped galvanized thin plates 1 can be neatly installed in the shape of a honeycomb mesh, which is convenient for subsequent welding operations. The adjustable clamping frame 2b can realize independent adjustment. The bottom plate 2a carries the stamped galvanized thin plate 1 on the top. The adjustable clamping frame 2b can change the installation size according to the needs, so as to adapt to different sizes. In the production of honeycomb mesh of number 1, the metal clamp 3c can be used to clamp the position where welding is required between the two stamped galvanized sheets 1, and the adjacent parallel fitting surfaces 1a of the two stamped galvanized sheets 1 can be tightly fitted, so that the stamped galvanized sheets 1 can be stably clamped when the solder melts during the brazing process, thereby improving the welding effect. The clamp position adjustment component 3d can adjust the position of the metal clamp 3c, and adjust the position of the metal clamp 3c according to the aperture formed by the honeycomb mesh and the size of the honeycomb mesh, so as to cope with the production process of honeycomb meshes with different apertures.

[0048] It is worth mentioning that the clamping method of the honeycomb mesh used in this equipment can be manually adjusted to realize the production process of honeycomb meshes of different sizes, and can play a better limiting clamping role for honeycomb meshes of different sizes and apertures, ensuring that they will not shift or loosen during the welding process, resulting in welding errors, thereby improving the welding effect and the practicability of the welding equipment.

[0049] When the welding equipment is working, firstly, the parallel fitting surfaces 1a of several stamped galvanized sheets 1 to be welded are evenly coated with solder, and several stamped galvanized sheets 1 are manually or mechanically moved to the adjustable clamping frame 2b according to the predetermined position, and the welding mold 2 is moved as a whole to the bottom of the compaction drive mechanism 4, and the positions of several metal clamps 3c are determined by the clamp position adjustment component 3d, and the clamping device 3 is driven to move by the output of the compaction drive mechanism 4, and the lower pressing plate 3a is driven to drive several metal clamps 3c that are synchronously driven with the lower pressing plate 3a to be inserted above the honeycomb net. At this time, the metal clamps 3c are clamping the stamped galvanized sheets. 1, it can also ensure that several stamped galvanized thin plates 1 are tightly attached to the bottom plate 2a, so that the heights of several stamped galvanized thin plates 1 remain consistent. After the clamping device 3 clamps the honeycomb net inside the welding mold 2, the compaction drive mechanism 4 releases the limit, and the welding mold 2 drives the clamping device 3 and the honeycomb net inside it to move into the drying device, and heats for a specific time at a predetermined constant temperature to melt the solder within the adjacent parallel bonding surfaces 1a of the two stamped galvanized thin plates 1, thereby welding the two adjacent stamped galvanized thin plates 1 to each other, and finally take the honeycomb net out of the drying device to cool it at room temperature to complete the welding function.

[0050] Further:

[0051] The adjustable clamping frame 2b includes a first vertical plate 2b1, a second vertical plate 2b2 and a spring 2b3. The first vertical plate 2b1, the second vertical plate 2b2 and the spring 2b3 are each provided with four groups. The first vertical plate 2b1 corresponds to the second vertical plate 2b2 one by one. The four groups of the first vertical plates 2b1 and the second vertical plates 2b2 are combined to form a limit frame capable of clamping and limiting one of the side walls of the honeycomb net. The first vertical plate 2b1 and the second vertical plate 2b2 are both vertically arranged. The first vertical plate 2b1 is provided with a horizontal slot 2b 11, a horizontal inserting strip 2b22 is provided on the second vertical plate 2b2 to fit with the horizontal slot 2b11, a horizontal limiting strip 2b12 is provided in the horizontal slot 2b11 to limit the second vertical plate 2b2, a horizontal limiting groove 2b23 is provided in the horizontal inserting strip 2b22 to be slidably connected with the horizontal limiting strip 2b12, and the second vertical plate 2b2 also includes a vertical connecting plate 2b21, and one end of the horizontal inserting strip 2b22 away from the first vertical plate 2b1 is fixedly connected to the vertical connecting plate 2b21, and the vertical connecting plate 2b21 The bottom end of the spring 2b3 contacts with the bottom plate 2a, and the spring 2b3 is horizontally arranged between one group of first vertical plates 2b1 and the second vertical plates 2b2. One end of the spring 2b3 is fixedly connected to one end of the first vertical plate 2b1 close to the vertical connecting plate 2b21, and the other end of the spring 2b3 is fixedly connected to a side wall of the vertical connecting plate 2b21 close to the first vertical plate 2b1. Two adjacent first vertical plates 2b1 located at one corner of the limit frame are fixedly connected to the bottom plate 2a to form a positioning angle. There are two groups of spacing adjustment components 2c, and the two groups of spacing adjustment components 2c are horizontally installed on the rectangular limit plate 2a1. The installation positions of the two groups of spacing adjustment components 2c are arranged perpendicular to each other, and one group of spacing adjustment components 2c is arranged on the spacing adjustment component 2c in the horizontal direction, and the spacing adjustment component 2c is transmission-connected to the side wall of the limit frame along the horizontal direction away from the positioning angle, and the other group of spacing adjustment components 2c is arranged on the spacing adjustment component 2c in the longitudinal direction, and the spacing adjustment component 2c is transmission-connected to the side wall of the limit frame along the longitudinal direction away from the positioning angle.

[0052] Based on the above embodiments, the problem that the welding fixture of the honeycomb mesh in the traditional welding equipment has poor adaptability and can only adapt to the clamping of the honeycomb mesh of a specific shape is solved. The corresponding first vertical plate 2b1 and the second vertical plate 2b2 cooperate to form a baffle that can limit one side of the honeycomb mesh, and can be extended or shortened along the length direction without affecting the limiting function, so as to match the installation of honeycomb meshes of different sizes. A limit frame for installing the honeycomb mesh is formed by four groups of first vertical plates 2b1 and second vertical plates 2b2. One end of the limit frame is fixed to the bottom plate 2a to form a positioning angle, and the size of the limit frame can be adjusted based on this. The limit frame is adjusted horizontally and vertically by two groups of spacing adjustment components 2c, respectively, so as to ensure the accuracy of the limit frame adjustment.

[0053] Further:

[0054] The spacing adjustment assembly 2c includes a limiting connection plate 2c1, a horizontal limiting rod 2c2 and a spacing adjustment device 2c3. The limiting connection plate 2c1 is vertically fixedly installed on the side wall of one of the first vertical plates 2b1, and the horizontal limiting rod 2c2 is horizontally arranged.

The spacing adjustment device 2c3 is installed on the rectangular limiting plate 2a1, and the output ends of the two groups of spacing adjustment devices 2c3 are respectively transmission-connected to the side walls of the limiting frame away from the positioning angle.

[0055] When adjusting the adjustable clamping frame 2b, the operator drives the output of the spacing adjustment device 2c3 to drive the first vertical plate 2b1 and the second vertical plate 2b2 to move closer to or away from each other, thereby realizing the spacing adjustment function. The position of the first vertical plate 2b1 can be limited by the limiting connecting plate 2c1 and the horizontal limiting rod 2c2, so that it is always on the same horizontal plane with the rectangular limiting plate 2a1, ensuring that the limiting frame always remains in a horizontal state when expanding or contracting, thereby ensuring the accuracy of adjustment of the adjustable clamping frame 2b.

[0056] Further:

[0057] The spacing adjustment device 2c3 includes a first threaded rod 2c31, a threaded transmission sleeve 2c32 and a locking bolt 2c33. The threaded transmission sleeve 2c32 is horizontally fixedly installed on the side wall of one side of the rectangular limiting plate 2a1. The first threaded rod 2c31 is horizontally arranged. The first threaded rod 2c31 is threadedly connected with the threaded transmission sleeve 2c32. The side of the first threaded rod 2c31 close to the limiting frame is axially connected to the outer side wall of one of the first vertical plates 2b1. The locking bolt 2c33 is arranged at an end of the first threaded rod 2c31 away from the first vertical plate 2b1. The end of the locking bolt 2c33 away from the threaded transmission sleeve 2c32 is provided with a first internal thread. The locking bolt 2c33 is threadedly connected to the outer side wall of the first threaded rod 2c31 through the first internal thread.

The outer side wall of the threaded transmission sleeve 2c32 is provided with an external thread that can be locked with the second internal thread of the locking bolt 2c33.

[0058] When the spacing adjustment device 2c3 is working, the operator rotates the first threaded rod 2c31 and performs threaded transmission through the threaded transmission sleeve 2c32 installed on the rectangular limiting plate 2a1 to realize the displacement of the first threaded rod 2c31 in the horizontal position, thereby pushing the grouped first vertical plate 2b1 and the second vertical plate 2b2 to move forward or backward synchronously to realize the adjustment function. After the adjustable clamping frame 2b is adjusted into place, the locking bolt 2c33 is rotated to make it move on the first threaded rod 2c31, and the locking bolt 2c33 is locked on the threaded transmission sleeve 2c32 to realize the overall locking function of the spacing adjustment device 2c3, thereby ensuring that the subsequent adjustable clamping frame 2b can stably clamp the honeycomb mesh during movement and welding operations.
