Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser processing, in particular to a wafer surface laser cladding equipment. BACKGROUND

[0002] With the rapid development of modern manufacturing industry, especially in the field of precision machining and surface treatment, the requirement for material surface quality is increasing. Laser cladding technology on wafer surface as an efficient surface treatment technology has been widely used in aerospace, mechanical manufacturing, electronic industry and other fields. The technology heats the metal powder to the melting point by laser beam and clads it to the surface of the substrate, thereby improving the wear resistance, corrosion resistance and high temperature resistance of the material surface.

[0003] Some existing devices need to transport metal-based powder during laser cladding, but powder recycling and reutilization are difficult, and powder agglomeration and uneven particle size problems are prone to occur during feeding, resulting in porosity and unmelting defects in the cladding layer, affecting the surface quality of the roller. Roller clamping, powder screening and conveying, laser cladding and other multi-processes require manual intervention, which is low in efficiency and poor in consistency. The roller is a cylindrical workpiece, and ordinary cladding equipment cannot achieve uniform powder feeding and synchronous laser scanning, resulting in uneven thickness of the cladding layer. SUMMARY

[0004] The present application aims to solve the problems of traditional powder feeding system, such as powder agglomeration and uneven particle size, which leads to defects such as porosity and unmelting in the cladding layer, affecting the surface quality of the roller, low automation degree, manual intervention in roller clamping, powder screening and conveying, laser cladding and other multi-processes, low efficiency and poor consistency, and poor adaptability to complex curved surfaces. The roller is a cylindrical workpiece, and ordinary cladding equipment cannot achieve uniform powder feeding and synchronous laser scanning, resulting in uneven thickness of the cladding layer.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a wafer surface laser cladding equipment, comprising: a support, characterized in that a motor one is fixedly installed on one side of the support, a U-shaped rotating plate is fixedly installed on the output end of the motor one, an electric push rod one is fixedly installed on the inner wall of the U-shaped rotating plate, a moving semicircle block is fixedly installed on one end of the electric push rod one, a fixed semicircle block is fixedly installed on the inner wall of the U-shaped rotating plate, the fixed semicircle block and the moving semicircle block are oppositely arranged, an arc-shaped material collecting box is fixedly installed on the inner wall bottom of the support, a gas cylinder is fixedly installed on the top of the support, a lifting plate is fixedly installed on the top of the gas cylinder, two vertical plates are fixedly installed on the top of the support, the lifting plate is slidingly connected on one side of the two vertical plates, two limiting rods are fixedly installed on the inner wall of the lifting plate, and a sliding block is slidingly connected on the outer surface of the two limiting rods.

[0006] The technical effects of the further scheme are: first, the roller is placed in the middle of the fixed semicircular block and the movable semicircular block, then the electric push rod one is started by the external power supply, the movable semicircular block is moved by the electric push rod one, at this time, the movable semicircular block and the fixed semicircular block can clamp and fix the roller, the arc-shaped material collecting box can collect the excess metal-based powder, avoiding the waste of the metal-based powder, which can be recycled, and the roller is rotated by starting the motor one, at this time, the cladding range of the roller can be increased.

[0007] As a preferred embodiment, the inner wall of the lifting plate is fixedly installed with an electric push rod two, one end of the electric push rod two is fixedly installed on the surface of the sliding block, the top of the sliding block is fixedly installed with a connecting strip, the bottom of the connecting strip is fixedly installed with a fiber laser, and one side of the sliding block is fixedly installed with a fixed strip.

[0008] The technical effects of the further scheme are: the surface of the roller can be laser cladded by the fiber laser, and can slide with the lateral sliding of the sliding block, and can also be raised and lowered with the sliding block, increasing the processing range of the fiber laser.

[0009] As a preferred embodiment, the inside of the fixed strip is movably embedded with a rotating rod, the outer surface of the rotating rod is movably sleeved with an inclined plate, the inside of the inclined plate is movably embedded with an auger blade, the outer surface of the auger blade is movably sleeved with a bottom plate, the bottom of the bottom plate is fixedly installed with two springs two, the bottom of the bottom plate is fixedly installed with two limiting telescopic rods, the bottom of the two springs two and the two limiting telescopic rods is fixedly connected with a horizontal plate, one side of the horizontal plate is fixedly connected with two supporting L strips, the two supporting L strips are fixedly connected to the bottom of the two fixed strips, and the top of the horizontal plate is fixedly installed with a motor two.

[0010] The technical effects of the further scheme are: when the metal-based powder enters above the inclined plate, the limiting telescopic rod rotates on the surface of the bottom plate, and the bottom plate vibrates under the limiting of the spring two and the limiting telescopic rod, so as to drive the inclined plate to vibrate, the vibration can quickly shake the metal-based powder into the inside of the feeding mechanism, avoiding the metal-based powder being stuck on the upper surface of the inclined plate and affecting the processing efficiency.

[0011] In a preferred embodiment, the output end of the second motor is fixedly connected to an elliptical block two, which rotates on the top of the base plate. A feeding mechanism is fixedly installed on one side of the horizontal plate, located directly below the inclined plate. A long tube is fixedly installed directly below the feeding mechanism, and an auger blade is rotatably connected inside the long tube. The output end of the second motor is movably fitted with a belt first via a pulley. One end of the belt first is movably fitted with a long rod via a pulley. The long rod is fixedly connected to one end of the auger blade, and a belt second is movably fitted on the surface of the long rod near one side via a pulley.

[0012] The technical effect of adopting the above-mentioned further solution is that the metal-based powder is rapidly vibrated into the interior of the feeding mechanism. When the second motor starts, it simultaneously drives the first belt to move through the pulley. At this time, the first belt drives the long rod to rotate through the pulley, and the long rod drives the auger blade to rotate. The metal-based powder inside the feeding mechanism enters the interior of the long tube and is conveyed inside by the rotation of the auger blade, and is conveyed to the top of the rolling mill processing area.

[0013] In a preferred embodiment, a rotating rod is movably sleeved at the top of the second belt, and an elliptical block is fixedly connected to one end of the rotating rod. The elliptical block rotates on the upper surface of the screening box. A screening box is fixedly installed on one side of the slider. Multiple sliding grooves are opened on the inner wall of the screening box, and a screening screen is slidably connected inside the multiple sliding grooves. The rotating rod is movably embedded in the inner wall of the screening box.

[0014] The technical effect of the above-mentioned further solution is as follows: the metal-based powder is poured into the upper surface of the screening screen inside the screening box, and then the motor two is started by an external power source. The motor two drives the belt one to rotate through the pulley at the output end. At this time, the top of the belt one drives the rotating rod to rotate through the pulley. The rotating rod drives the elliptical block one to rotate on the upper surface of the screening screen. At this time, under the limit of the spring one at the bottom of the four sides, the screening screen moves up and down back and forth inside the slide groove, thereby causing the screening screen to vibrate. Larger metal-based powder particles are retained on its upper surface, while smaller metal-based powder particles are screened to the bottom of the screening box, which can screen metal-based powder and improve the powder utilization efficiency.

[0015] In a preferred embodiment, a plurality of springs are fixedly connected to the bottom of the screening screen, and a plurality of limiting blocks are fixedly connected to the inner wall of the screening box, with each of the springs fixedly connected to the top of the limiting blocks.

[0016] The technical effect of adopting the above-mentioned further solution is that it is mainly used to limit the vibration of the screening screen.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0018] 1. In this embodiment of the invention, the material falls into the upper surface of the inclined plate through the discharge hole at the bottom of the sieve box. When the second motor is started, it drives the second elliptical block to rotate. The second elliptical block rotates on the upper surface of the base plate. Under the limiting telescopic rod at its bottom and the second spring, the inclined plate vibrates, causing the metal-based powder on the upper surface of the inclined plate to be stuck above the inclined plate. The metal-based powder is rapidly vibrated into the inside of the feeding mechanism. When the second motor is started, it drives the first belt to move through the pulley. At this time, the first belt drives the long rod to rotate through the pulley. The long rod drives the auger blade to rotate. The metal-based powder inside the feeding mechanism enters the inside of the long tube and is transported inside by the rotation of the auger blade. It is transported to the top of the roller processing area. Then, the fiber laser is started to clad the surface of the roller and cooperate with the metal-based powder.

[0019] 2. In this embodiment of the invention, metal-based powder is poured onto the upper surface of the screening screen inside the screening box. Then, motor two is started by an external power source. Motor two drives belt one to rotate through the pulley at the output end. At this time, the top of belt one drives the rotating rod to rotate through the pulley. The rotating rod drives elliptical block one to rotate on the upper surface of the screening screen. At this time, under the limitation of spring one at the bottom of the four sides, the screening screen moves up and down inside the chute, thereby causing the screening screen to vibrate. Larger metal-based powder particles are retained on its upper surface, while smaller metal-based powder particles are screened to the bottom of the screening box.

[0020] 3. In this embodiment of the invention, during the cladding process, an electric push rod two is started by an external power source. The electric push rod two pushes the slider to slide on the outer surface of the limit rod. At this time, the fiber laser and the powder output mechanism can move laterally. The cylinder can be started to push the entire processing mechanism up and down along the vertical plate, which makes the processing more efficient and the cladding range wider. At the same time, a motor one is started by an external power source. The motor one drives the roller to rotate. When rotating, multiple places on its outer surface can be clad, which improves efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8This embodiment provides a technical solution: a laser cladding device for wafer surfaces, comprising: a support 101, characterized in that: a motor 102 is fixedly installed on one side of the support 101; a U-shaped rotating plate 103 is fixedly installed at the output end of the motor 102; an electric push rod 104 is fixedly installed on the inner wall of the U-shaped rotating plate 103; a movable semicircular block 105 is fixedly installed at one end of the electric push rod 104; and a fixed semicircular block 106 is fixedly installed on the inner wall of the U-shaped rotating plate 103. 06 is positioned opposite to the movable semicircular block 105. An arc-shaped receiving box 107 is fixedly installed on the bottom of the inner wall of the support 101. A cylinder 108 is fixedly installed on the top of the support 101. A lifting plate 110 is fixedly installed on the top of the cylinder 108. Two vertical plates 109 are fixedly installed on the top of the support 101. The lifting plate 110 is slidably connected to one side of the two vertical plates 109. Two limiting rods 111 are fixedly installed on the inner wall of the lifting plate 110. A slider 113 is slidably connected to the outer surface of the two limiting rods 111.

[0033] In use, the roller is first placed between the fixed semicircular block 106 and the movable semicircular block 105. Then, the electric push rod 104 is started by an external power source. The electric push rod 104 pushes the movable semicircular block 105 to move. At this time, the movable semicircular block 105 and the fixed semicircular block 106 can clamp and fix the roller. The arc-shaped collection box 107 can collect the excess metal-based powder, avoiding the waste of metal-based powder, which can be recycled. After starting the motor 102, the roller is driven to rotate, which can increase the coating range of the roller.

[0034] like Figures 1 to 8 As shown, in one embodiment, an electric push rod 112 is fixedly installed on the inner wall of the lifting plate 110. One end of the electric push rod 112 is fixedly installed on the surface of the slider 113. A connecting strip 114 is fixedly installed on the top of the slider 113. A fiber laser 115 is fixedly installed on the bottom of the connecting strip 114. A fixing strip 116 is fixedly installed on one side of the slider 113. The fiber laser 115 can perform laser cladding on the surface of the roll. It can also slide with the lateral sliding of the slider 113 and rise and fall with the slider 113, thereby increasing the processing range of the fiber laser 115.

[0035] like Figures 1 to 8As shown, in one embodiment, a rotating rod 124 is movably embedded inside the fixing bar 116, and an inclined plate 125 is movably sleeved on the outer surface of the rotating rod 124. An auger blade 138 is movably embedded inside the inclined plate 125, and a base plate 126 is movably sleeved on the outer surface of the auger blade 138. Two springs 127 are fixedly installed at the bottom of the base plate 126, and two limiting telescopic rods 128 are fixedly installed at the bottom of the base plate 126. A horizontal plate 137 is fixedly connected to the bottom of the two springs 127 and the two limiting telescopic rods 128. One side of the horizontal plate 137 is fixedly connected to... Two support L-bars 129 are fixedly connected to the bottom of two fixed bars 116. A motor 130 is fixedly installed on the top of the horizontal plate 137. When the metal-based powder enters above the inclined plate 125, the limiting telescopic rod 128 rotates on the surface of the base plate 126. Under the limitation of the spring 127 and the limiting telescopic rod 128, the base plate 126 vibrates, thereby driving the inclined plate 125 to vibrate. The vibration can quickly shake the metal-based powder into the inside of the feeding mechanism 135, avoiding the powder from getting stuck on the upper surface of the inclined plate 125 and affecting the processing efficiency.

[0036] like Figures 1 to 8 As shown, in one embodiment, an elliptical block 131 is fixedly connected to the output end of motor 130. Elliptical block 131 rotates on the top of base plate 126. A feeding mechanism 135 is fixedly installed on one side of horizontal plate 137. The feeding mechanism 135 is located directly below inclined plate 125. A long tube 136 is fixedly installed directly below the feeding mechanism 135. An auger blade 138 is rotatably connected inside the long tube 136. A belt 133 is movably sleeved on the output end of motor 130 via a pulley. A long rod 132 is movably sleeved on one end of belt 133 via a pulley. The long rod 132 is fixedly connected to one end of the auger blade 138. A second belt 134 is movably mounted on one side of the long rod 132 via a pulley. The metal-based powder is rapidly vibrated into the inside of the feeding mechanism 135. When the second motor 130 starts, it simultaneously drives the first belt 133 to move via the pulley. At this time, the first belt 133 drives the long rod 132 to rotate via the pulley. The long rod 132 drives the auger blade 138 to rotate. The metal-based powder inside the feeding mechanism 135 enters the inside of the long tube 136 and is conveyed inside by the rotation of the auger blade 138. The smaller pitch of the auger blade 138 combined with the lower speed can achieve more uniform conveying and convey it to the top of the rolling mill.

[0037] like Figures 1 to 8As shown, in one embodiment, a rotating rod 118 is movably sleeved on the top end of the belt 134. One end of the rotating rod 118 is fixedly connected to an elliptical block 119, which rotates on the upper surface of the sieve box 117. The sieve box 117 is fixedly installed on one side of the slider 113. The inner wall of the sieve box 117 has multiple grooves 121, and a screen 120 is slidably connected inside the multiple grooves 121. The rotating rod 118 is movably embedded in the inner wall of the sieve box 117. Metal-based powder is poured into the upper surface of the screen 120 inside the sieve box 117. Then, the motor 130 is started by an external power source. 30 drives belt 133 to rotate via the pulley at the output end. At this time, the top of belt 133 drives rotating rod 118 to rotate via the pulley. Rotating rod 118 drives elliptical block 119 to rotate on the upper surface of screen 120. At this time, under the limit of spring 123 at the bottom, screen 120 moves up and down inside slide 121, thereby causing screen 120 to vibrate. Larger metal-based powder particles are retained on its upper surface, while smaller metal-based powder particles are screened to the bottom of screen box 117, which can screen metal-based powder and improve the powder utilization efficiency.

[0038] like Figures 1 to 8 As shown, in one embodiment, a plurality of springs 123 are fixedly connected to the bottom of the screening screen 120, and a plurality of limiting blocks 122 are fixedly connected to the inner wall of the screening box 117. The plurality of springs 123 are fixedly connected to the top of the limiting blocks 122, mainly for limiting the vibration of the screening screen 120.

[0039] Working principle: In use, the roller is first placed between the fixed semicircular block 106 and the movable semicircular block 105. Then, the electric push rod 104 is started by an external power source. The electric push rod 104 pushes the movable semicircular block 105 to move. At this time, the movable semicircular block 105 and the fixed semicircular block 106 can clamp and fix the roller. Then, the metal-based powder is poured into the upper surface of the screen 120 inside the sieve box 117. Then, the motor 130 is started by an external power source. The motor 130 drives the belt 133 to rotate through the pulley at the output end. At this time, the top of the belt 133 drives the rotating rod 118 to rotate through the pulley. The rotating rod 118 then rotates. Rotating rod 118 drives elliptical block 119 to rotate on the upper surface of screening screen 120. At this time, under the limiting of spring 123 at the bottom, screening screen 120 moves up and down inside slide 121, causing screening screen 120 to vibrate. Larger metal-based powder particles are retained on its upper surface, while smaller metal-based powder particles are screened to the bottom of screening box 117 and fall into the upper surface of inclined plate 125 through the discharge hole at the bottom of screening box 117. At this time, when motor 130 is started, it drives elliptical block 131 to rotate. Elliptical block 131 rotates on the upper surface of base plate 126, and the limiting telescopic rod 128 and spring 127 at its bottom... Under the combined limiting action, the inclined plate 125 vibrates, causing the metal-based powder on the upper surface of the inclined plate 125 to become stuck above it. The metal-based powder is rapidly vibrated into the feeding mechanism 135. When the second motor 130 starts, it simultaneously drives the first belt 133 via the pulley. At this time, the first belt 133 drives the long rod 132 to rotate via the pulley. The long rod 132 drives the auger blade 138 to rotate. The metal-based powder inside the feeding mechanism 135 enters the long tube 136 and is conveyed inside by the rotation of the auger blade 138. The smaller pitch of the auger blade 138 and the lower speed can achieve more uniform conveying, conveying the powder to the area above the rolling mill. Then, the surface of the roll is clad by activating the fiber laser 115, which works in conjunction with the metal-based powder. During the cladding process, the electric push rod 112 is activated by an external power source. The electric push rod 112 pushes the slider 113 to slide on the outer surface of the limit rod 111. At this time, the fiber laser 115 and the powder outlet mechanism can move laterally. The cylinder 108 can be activated to push the entire processing mechanism up and down on the outer surface of the vertical plate 109, resulting in higher processing efficiency and a wider cladding range. At the same time, the motor 102 is activated by an external power source, which drives the roll to rotate. During the rotation, multiple areas on its outer surface can be clad, improving efficiency.
