[0002] In recent years, with the continuous development and popularization of communication electronic technology, communication devices have been widely used in large quantities. For example, antenna oscillators and components often use alloy materials such as Al that are light, cheap, and have good thermoelectric properties. However, aluminum parts have poor weldability and usually require electroplating to modify their surface before brazing. However, the electroplating process faces serious pollution and high energy consumption.

[0003] In the related technologies, in order to solve the pollution problems and high energy consumption problems caused by the electroplating process, an ultrasonic assisted cladding technology has been proposed. When this technology is implemented, an ultrasonic vibration device is applied to the molten tin pool, and the ultrasonic energy is transmitted to the surface of the workpiece through the entire molten tin pool.

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0041] As the background technology, the workpiece in the related art has poor cladding consistency and low cladding quality. The inventors have found that the reason for this problem is that in the related art, the ultrasonic horn is connected to the molten pool, and the ultrasonic energy is transmitted along the molten pool and the liquid solder. Specifically, the horn of the ultrasonic vibration device is usually applied to the molten tin pool, and the ultrasonic energy needs to be transmitted to the workpiece surface through the entire molten tin pool, that is, the sound field propagation path involves the entire molten pool and all solders, and the sound field energy loss is serious. The ultrasonic energy transmitted to the workpiece surface is very limited, and the cladding efficiency is low, so that the ultrasonic tinning device can only be adapted to the flux-free tinning of workpieces with good solder wettability, and it is difficult to achieve surface cladding of difficult-to-wet workpieces; in addition, there are differences in the sound pressure intensity of the workpiece at different positions in the molten tin pool, and the cavitation effect in the edge area of ​​the cladding layer is weak, which makes the cladding consistency and quality poor. However, although adding multiple ultrasonic horns to the molten tin pool can enhance the ultrasonic energy in the molten pool to a certain extent, adding multiple groups of sound sources in the molten pool is likely to cause mutual interference between sound waves. The mutual coupling between the strong vibration area and the weak vibration area in the molten pool can easily lead to the formation of stronger strong vibration area or weaker weak vibration area in the molten pool, making it difficult to ensure the cladding quality.

[0042] Based on the above reasons, the present application provides an ultrasonic assisted cladding component and a cladding device, which can improve the cladding efficiency and at the same time improve the workpiece cladding consistency and workpiece cladding quality.

[0043] See also Figure 1 , Figure 3 and Figure 4 , Figure 1A structural diagram of a cladding device according to an embodiment of the present application is shown. Figure 3 Shows Figure 1 A schematic diagram of a working state of the ultrasonic assisted cladding component 10 in the structure shown. Figure 4 Shows Figure 1 Another schematic diagram of the working state of the ultrasonic assisted cladding component 10 in the structure shown. An ultrasonic assisted cladding component 10 provided in one embodiment of the present application includes: a furnace 11, a carrier 12, a first moving mechanism 13, an ultrasonic component 14 and a second moving mechanism (not shown in the figure). The furnace 11 is used to install a first cladding material and heat the first cladding material. When the first cladding material is heated to a preset temperature range, the first cladding material inside the furnace 11 is in a molten state, so that a cladding layer can be formed on the wall surface of the workpiece 20. The workpiece 20 includes but is not limited to a radiation unit or a phase shifter. In addition, specifically, the furnace 11 is not limited to a temperature-controlled furnace, and a PID or PLC temperature controller can be specifically selected to achieve precise control and regulation of the temperature of the first cladding material. In addition, the furnace 11 also has a heat preservation function. Based on its good heat preservation effect, it can prevent the heat of the first cladding material from leaking outward, thereby saving energy. The first cladding material is solder, including but not limited to tin material or silver material, etc. After being clad on the surface of the workpiece 20 to form a soldering layer, it can be easily welded to other components.

[0044] In addition, the carrier 12 is used to place the workpiece 20 to be processed. The first moving mechanism 13 is connected to the carrier 12, and is used to drive the carrier 12 to immerse the area to be processed of the workpiece into the first cladding material, and to drive the carrier 12 to move the workpiece 20 out of the furnace 11. The ultrasonic component 14 has the function of generating immersion driving energy, and the ultrasonic component 14 includes an ultrasonic horn 141. The second moving mechanism is connected to the ultrasonic component 14, and the second moving mechanism is used to drive the ultrasonic horn 141 to move to the surface of the workpiece 20, so that the ultrasonic horn 141 and the surface of the workpiece 20 abut against each other, and the ultrasonic vibration is applied to the surface of the workpiece 20 through the ultrasonic horn 141, or, after the surface cladding treatment of the workpiece 20 is completed, the ultrasonic horn 141 is separated from the surface of the workpiece 20.

[0045] When the above-mentioned ultrasonic assisted cladding component 10 is in use, the furnace 11 heats the first cladding material so that the first cladding material is heated to a preset temperature range; the first moving mechanism 13 drives the carrier 12 to move to the inside of the furnace 11 so that the workpiece 20 is immersed in the first cladding material, and at the same time the second moving mechanism drives the ultrasonic component 14 to move, and the ultrasonic welding head 141 abuts against the surface of the workpiece 20, so that the ultrasonic welding head 141 can apply ultrasonic vibration to the surface of the workpiece 20, so that the sound field energy can be transmitted to the surface of the workpiece 20 through the ultrasonic welding head 141, the ultrasonic energy loss is small, and the cladding area of ​​the workpiece 20 is subjected to a strong cavitation effect, which is more suitable for the automatic cladding of the surface of difficult-to-wet materials, overcoming the pollution problem caused by conventional electroplating technology, and the equipment has high production efficiency, good product consistency, and high cladding layer quality.

[0046] Among them, when the second moving mechanism drives the ultrasonic component 14 to move, it pushes the ultrasonic welding head 141 to contact with the workpiece 20 to apply ultrasonic vibration to the surface of the workpiece 20. By flexibly adjusting and controlling the pressure applied by the ultrasonic welding head 141 to the workpiece 20, the cladding quality of the first cladding material on the surface of the workpiece 20 can be improved accordingly.

[0047] See also Figure 3 and Figure 4 In one embodiment, the ultrasonic assembly 14 further includes an ultrasonic generator (not shown in the figure) and a pressure sensor (not shown in the figure). The ultrasonic generator and the pressure sensor are both connected to the ultrasonic horn 141. The ultrasonic generator is used to transmit ultrasonic energy to the ultrasonic horn 141, and the pressure sensor is used to sense the pressure applied by the ultrasonic horn 141 to the workpiece 20.

[0048] See also Figure 3 and Figure 4 In one embodiment, the ultrasonic generator, the pressure sensor, and the second moving mechanism are all used to be electrically connected to the controller. In this way, the ultrasonic generator, the pressure sensor, and the second moving mechanism work in coordination under the control of the controller, so that the pressure applied by the ultrasonic horn 141 to the workpiece 20 is within a preset range, thereby improving the processing quality of the workpiece 20. Among them, the pressure sensor can be used to sense and feedback the contact state between the ultrasonic component 14 and the workpiece 20. Specifically, when the pressure sensor senses that the pressure applied by the ultrasonic horn 141 to the workpiece 20 is too small, the controller controls the second moving mechanism to drive the ultrasonic horn 141 to press down to increase the pressure; conversely, when the pressure sensor senses that the pressure applied by the ultrasonic horn 141 to the workpiece 20 is too large, the controller controls the second moving mechanism to drive the ultrasonic horn 141 to move away from the workpiece 20 to reduce the pressure.

[0049] See also Figure 3 and Figure 4In some embodiments, the first moving mechanism 13 is electrically connected to the controller. Under the control of the controller, the first moving mechanism 13 drives the carrier 12 into the furnace 11 and immerses it in the first cladding material, and after forming a cladding layer on the surface of the workpiece 20, the carrier 12 is moved out of the furnace 11.

[0050] In one embodiment, the ultrasonic horn 141, the ultrasonic generator and the pressure sensor are all provided in plurality, each ultrasonic generator is provided in correspondence with each ultrasonic horn 141, and each pressure sensor is provided in correspondence with each ultrasonic horn 141. A plurality of workpieces 20 can be placed on the carrier 12, and each ultrasonic horn 141 is provided in correspondence with each workpiece 20. In this way, when each ultrasonic horn 141 abuts against each workpiece 20, ultrasonic vibration can be synchronously performed on each workpiece 20, so that each ultrasonic horn 141 is loaded on the surface of each workpiece 20, the cavitation effect is intense, and it is easier to achieve rapid cladding of difficult-to-wet materials, and a cladding layer is synchronously formed on the surface of each workpiece 20, with good product consistency and high production efficiency.

[0051] In this embodiment, the pressure sensor can be a tension and compression bidirectional sensor. In practice, when the contact pressure between the ultrasonic welding head 141 and the workpiece 20 reaches the rated value, the controller controls the ultrasonic generator to start applying ultrasonic vibration. The frequency of the ultrasonic generator can be selected from 20kHz to 80kHz, the available power is 50W to 5000W, and the vibration time can be selected from 0.1s to 100s.

[0052] See also Figure 3 In one embodiment, the ultrasonic assisted cladding assembly 10 further includes a third moving mechanism (not shown in the figure) and a first scraper 15 movably disposed on the top of the furnace 11. The third moving mechanism is connected to the first scraper 15, and the third moving mechanism is used to drive the first scraper 15 to move. Specifically, the first scraper 15 includes but is not limited to a scraper, a scraper, etc., as long as it can scrape off the slag on the liquid surface during the movement. In this way, before the first moving mechanism 13 drives the carrier 12 and the workpiece 20 thereon to enter the interior of the furnace 11, the third moving mechanism drives the first scraper 15 to reciprocate, thereby scraping off the slag on the liquid surface, so that after the first moving mechanism 13 drives the carrier 12 and the workpiece 20 thereon to enter the interior of the furnace 11, there is no slag residue in the first cladding material in the surrounding area of ​​the workpiece 20, which can improve the processing quality of the workpiece 20 and reduce the adverse effects of the slag on the quality of the workpiece 20.

[0053] The oxidized slag, i.e., the first cladding material at the liquid surface, is oxidized by contact with air to form a metal oxide film.

[0054] In some embodiments, the ultrasonic assisted cladding assembly 10 further includes a first collecting device disposed outside the furnace 11. The first collecting device includes but is not limited to a collecting cup, a collecting pool, a collecting box, etc. The first collecting device collects the oxidized slag scraped off the liquid surface by the first scraping member 15 and recycles it.

[0055] See also Figure 3 In one embodiment, the ultrasonic assisted cladding assembly 10 further includes a sensing probe 16 disposed on the carrier 12. The sensing probe 16 and the first moving mechanism 13 are both used to be electrically connected to the controller, and the sensing probe 16 and the first moving mechanism 13 cooperate under the control of the controller to control the immersion depth of the workpiece 20. Specifically, when the sensing probe 16 contacts the liquid surface of the furnace 11, the controller controls the first moving mechanism 13 to stop the descending movement. In this way, by detecting the liquid surface position through the sensing probe 16 disposed on the carrier 12 and feeding back to the controller in a timely manner, the controller can control the first moving mechanism 13 to stop moving accordingly, thereby realizing accurate control of the diving depth of the workpiece 20, which can be beneficial to improving the surface treatment quality of the workpiece 20.

[0056] See also Figure 3 In one embodiment, the ultrasonic assisted cladding assembly 10 further includes a rangefinder 17 disposed on the carrier 12. The rangefinder 17 is used to measure the liquid level of the furnace 11. Specifically, the rangefinder 17 includes but is not limited to a laser rangefinder, an ultrasonic rangefinder, and the like. In this way, by detecting the liquid level of the furnace 11, and judging whether the amount of the first cladding material in the furnace 11 exceeds the set range according to the detected size of the liquid level, when the liquid level is low, that is, the amount of the first cladding material in the furnace 11 exceeds the set range, the first cladding material is added to the furnace 11.

[0057] See also Figure 3 In one embodiment, the carrier 12 includes two split panels 121 that can be spliced ​​and connected.

[0058] See also Figure 3 In one embodiment, the carrier 12 is provided with an opening 122 for placing the workpiece 20, and the opening 122 is provided as one or more. Thus, by providing the opening 122, the workpiece 20 to be clad can be conveniently placed in mid-air.

[0059] In one embodiment, a protrusion is disposed at the edge of the carrier 12 to engage with the edge of the slot of the furnace 11 .

[0060] In some embodiments, the carrier 12 is made of materials including but not limited to stainless steel, aluminum, and polymer materials, and can be flexibly selected and configured according to actual needs, which is not limited here.

[0061] In some embodiments, the carrier 12 is configured as a composite plate structure, that is, a plurality of plate materials are assembled together.

[0062] See also Figure 3 and Figure 4 In some embodiments, the carrier 12 is provided with a lifting lug 123, and the lifting lug 123 is, for example, respectively arranged at opposite ends of the carrier 12, and at least one lifting lug 123 is arranged at any end of the carrier 12. The first moving mechanism 13 includes a suspension rod 131, and the suspension rod 131 is provided with a suspension 1311 corresponding to the lifting lug 123. When the suspension 1311 and the lifting lug 123 cooperate with each other, the carrier 12 is connected, and the carrier 12 can be stably lifted and driven to move. On the contrary, when the cladding process of the workpiece 20 on the carrier 12 is completed, when the suspension 1311 releases the lifting lug 123, the carrier 12 can be taken out and the unloading action can be performed. In other embodiments, according to the specific structure of the workpiece, a suitable carrier structure can be selected as needed.

[0063] Under the control instruction of the controller, the first moving mechanism 13 can not only drive the carrier 12 in the vertical direction (that is, Figure 3 The lifting movement of the carrier 12 in the Z-axis direction shown in FIG. 1 can also be realized by driving the carrier 12 in the horizontal direction (i.e., as shown in FIG. Figure 3 The first moving mechanism 13 can be moved to different workstations (in the X-axis direction shown in the figure), so as to realize, for example, loading action, cladding treatment, infiltration and blowing treatment, unloading action, etc. In some embodiments, the first moving mechanism 13 includes but is not limited to being set as a three-axis motion mechanism, that is, it can realize movement in three directions of X-axis, Y-axis and Z-axis. It should be noted that the implementation method of the first moving mechanism 13 can include any linear reciprocating motion mechanism such as a slide rail, an electric cylinder, a cylinder or an electric push rod. In addition, the second moving mechanism is similar to the third moving mechanism and is not limited here.

[0064] See also Figure 3 In addition, specifically, each split plate 121 has a lifting ear 123 at two opposite ends. There are four suspension rods 131, and each suspension rod 131 is correspondingly arranged with each lifting ear 123. The hangers 1311 of the four suspension rods 131 are respectively connected with each lifting ear 123 of the two split plates 121, so as to realize the connection between the first moving mechanism 13 and the carrier 12, and can drive the carrier 12 to move along various directions including but not limited to the X-axis, the Y-axis and the Z-axis. One pair of suspension rods 131 is connected to one of the split plates 121, and the other pair of suspension rods 131 is connected to the other split plate 121. The first moving mechanism 13 can also drive one pair of suspension rods 131 to open and close with the other pair of suspension rods 131, so as to realize the opening and closing movement of the two split plates 121, so as to load each workpiece 20 or unload each workpiece 20.

[0065] See also Figure 1 , Figure 3 and Figure 4 In one embodiment, a cladding device is provided, and the cladding device includes the ultrasonic assisted cladding assembly 10 of any of the above embodiments.

[0066] When the above-mentioned cladding device is in use, the furnace 11 heats the first cladding material so that the first cladding material is heated to a preset temperature range; the first moving mechanism 13 drives the carrier 12 to move to the inside of the furnace 11 so that the workpiece 20 is immersed in the first cladding material, and at the same time the second moving mechanism drives the ultrasonic component 14 to move, and the ultrasonic welding head 141 abuts against the surface of the workpiece 20, so that the ultrasonic welding head 141 can apply ultrasonic vibration to the surface of the workpiece 20, so that the sound field energy can be transmitted to the surface of the workpiece 20 through the ultrasonic welding head 141, the ultrasonic energy loss is small, and the cladding area of ​​the workpiece 20 is subjected to a strong cavitation effect, which is more suitable for the automatic cladding of the surface of difficult-to-wet materials, overcoming the pollution problem caused by conventional electroplating technology, and the equipment has high production efficiency, good product consistency, and high cladding layer quality.

The preheating component 30 is used to preheat the workpiece 20; the ultrasonic assisted cladding component 10 is used to ultrasonically clad the workpiece 20 after the preheating treatment; the infiltration component 40 is used to infiltrate the workpiece 20 after the ultrasonic cladding treatment; and the air blowing component is used to blow the workpiece 20 after the infiltration treatment. In this way, before the ultrasonic assisted cladding component 10 performs the ultrasonic cladding treatment step on the workpiece 20, the preheating component 30 also performs preheating treatment on the workpiece 20, which can improve the cladding treatment quality of the workpiece 20 inside the furnace 11; in addition, after the ultrasonic assisted cladding component 10 performs the ultrasonic cladding treatment step on the workpiece 20, the infiltration component 40 also performs infiltration and blowing treatment on the workpiece 20, which can help eliminate gaps / pores in the edge area of ​​the cladding layer, remove excess solder in the cladding layer, make the surface of the cladding layer smoother, improve the quality of the cladding layer, and significantly improve the equipment adaptability and cladding quality.

[0068] In some embodiments, since the first moving mechanism 13 can move in three axes, under the control of the controller, it can not only transfer the workpiece 20 and the carrier 12 that have been preheated by the preheating component 30 to the furnace 11, but also transfer the workpiece 20 and the carrier 12 that have completed the cladding treatment in the furnace 11 to the infiltration component 40, thereby realizing automated operation and high production efficiency.

[0069] It should be noted that the first moving mechanism 13 can be different transmission mechanisms of a transmission system to perform actions in each area, or it can be the same moving mechanism to drive the carrier in multiple areas (preheating treatment, ultrasonic cladding treatment, infiltration treatment, and blanking treatment).

The infiltration furnace 41 is used to install the second cladding material and heat the second cladding material to keep the second cladding material at a preset temperature. The first moving mechanism 13 is also used to drive the carrier 12 to immerse the to-be-processed area of ​​the workpiece 20 into the second cladding material, and drive the carrier 12 to move the workpiece 20 out of the infiltration furnace 41.

[0073] In addition, the cladding device also includes an air knife assembly 42. The air knife assembly 42 is used to be arranged relative to the surface of the workpiece 20, and to blow air to the cladding layer on the surface of the workpiece 20, thereby helping to eliminate gaps / pores in the edge area of ​​the cladding layer, remove excess solder in the cladding layer, make the surface of the cladding layer smoother, improve the quality of the cladding layer, and significantly improve the adaptability of the equipment and the cladding quality.

[0074] In some embodiments, under the control of the controller, the first moving mechanism 13 enables the carrier 12 to enter the infiltration furnace 41 multiple times, and to be taken out of the infiltration furnace 41 multiple times, that is, the first moving mechanism 13 reciprocates up and down along the Z axis to ensure that the cladding layer of the workpiece 20 is repeatedly immersed in the infiltration pool to complete the infiltration. In addition, after each infiltration, the carrier 12 drives the workpiece 20 to be taken out of the infiltration furnace 41 each time, and transfers the workpiece 20 to the blowing area. A plurality of high-temperature, gas-protected air knife assemblies 42 at different angles are arranged above the infiltration furnace 41. The nozzle can blow out a high-temperature, high-speed airflow to remove excess solder from the cladding layer, wherein the gas is a compressed protective gas such as nitrogen and argon. In this way, repeated infiltration and repeated blowing treatment of the cladding layer on the surface of the workpiece 20 can improve the processing quality, so that it can help to eliminate pores / gaps in the edge area of ​​the cladding layer, improve the quality of the cladding layer, and significantly improve the equipment adaptability and cladding quality.

[0075] In some embodiments, similar to the melting furnace 11, the infiltration furnace 41 also has a heat preservation function, and when the second cladding material is heated to a preset temperature range, the second cladding material inside the infiltration furnace 41 is in a molten state. In addition, based on its good heat preservation effect, it can prevent the heat of the second cladding material from leaking out, thereby saving energy.

[0076] In some embodiments, the infiltration furnace 41 includes but is not limited to a temperature-controlled furnace. In addition, the liquid level in the infiltration pool should be higher than the liquid level in the cladding pool.

[0077] See also Figure 1 and Figure 5 In one embodiment, the infiltration assembly 40 further includes a fourth moving mechanism and a second scraper movably disposed on the top of the infiltration furnace 41. The fourth moving mechanism is connected to the second scraper, and the fourth moving mechanism is used to drive the second scraper to move. Specifically, similar to the first scraper 15, the second scraper includes but is not limited to a scraper, a scraper, etc., as long as the slag on the liquid surface can be scraped off during the movement. In this way, before the first moving mechanism 13 drives the carrier 12 and the workpiece 20 thereon to enter the immersion furnace, the fourth moving mechanism drives the second scraper to reciprocate, thereby scraping off the slag on the liquid surface, so that after the first moving mechanism 13 drives the carrier 12 and the workpiece 20 thereon to enter the immersion furnace, there is no slag residue in the second cladding material in the surrounding area of ​​the workpiece 20, which can improve the processing quality of the workpiece 20 and reduce the adverse effects of the slag on the quality of the workpiece 20.

[0078] In some embodiments, the infiltration assembly 40 further includes a second collecting device disposed outside the furnace 11. The second collecting device includes but is not limited to a collecting cup, a collecting pool, a collecting box, etc. The second collecting device collects the oxidized slag scraped off the liquid surface by the second scraping member and recycles it.

[0079] In one embodiment, the air knife assembly 42 includes an air knife duct, an air knife nozzle, a temperature sensor and a heater. The air knife duct is connected to the air knife nozzle. The temperature sensor is used to sense the gas temperature in the air knife duct, and the heater is used to heat the gas in the air knife duct. The cladding device also includes a controller, and the temperature sensor and the heater are electrically connected to the controller. In this way, the gas temperature inside the air knife duct is sensed by the temperature sensor, and the controller controls the heater to work accordingly according to the gas temperature inside the air knife duct, so that the gas temperature is adjusted to a preset value, so that the nozzle can generate a high-temperature and high-speed airflow and act on the surface of the workpiece 20, thereby improving the quality of the surface cladding layer of the workpiece 20.

[0080] In some embodiments, the number of air knife assemblies 42 is set according to the number of workpieces 20 on the carrier 12. Specifically, in one embodiment, one workpiece 20 corresponds to one air knife assembly 42, that is, one air knife assembly 42 blows high-temperature and high-speed airflow to the surface of one workpiece 20. In another embodiment, one workpiece 20 corresponds to at least two air knife assemblies 42, and the at least two air knife assemblies 42 blow high-temperature and high-speed airflow to the surface of the workpiece 20 from different angles. In another embodiment, one air knife assembly 42 corresponds to each workpiece 20, specifically, one air knife assembly 42 is provided with a plurality of air knife ducts and a plurality of air knife nozzles, and at least one or more nozzles are set corresponding to one workpiece 20.

[0081] See also Figure 1 and Figure 6 In one embodiment, the cladding device further includes a material unloading support 50 . The first moving mechanism 13 is also used to transfer the workpiece 20 and the carrier 12 processed by the ultrasonic assisted cladding assembly 10 or the infiltration assembly 40 to the material unloading support 50 .

[0082] See also Figure 1 and Figure 6 In some embodiments, the unloading support 50 includes two first support plates 51 arranged in parallel and spaced apart and a second support plate 52 connecting the two first support plates 51. The second support plate 52 is arranged tilted relative to the horizontal plane. In this way, the first moving mechanism 13 places the workpiece 20 and the carrier 12 after the cladding treatment or the infiltration and blowing treatment on the unloading support 50, and the carrier 12 and the workpiece 20 after the immersion plating are slid out along the second support plate 52.
