[0002] During the production process of LED lamps, pin welding is a key process for connecting the LED chip to the external circuit, directly affecting the conductivity, heat dissipation, and long-term reliability of the product. With the development of LED technology towards miniaturization, high density, and diverse applications (such as lighting, display, automotive electronics, etc.), the limitations of traditional welding technology have gradually emerged, driving the iterative upgrade of welding equipment.

[0003] Currently, the existing pin welding devices lack a grinding measure when welding iron-based galvanized pins, resulting in a situation where the solder paste cannot adhere during welding, and the welding is carried out by a simple contact method, making it difficult to ensure the welding contact area, thus affecting the welding quality.

The rotation of the grinding roller drives the pin to move on the surface of the strip-shaped grinding block, causing the pin to slide on the surface of the strip-shaped grinding block, thereby grinding the zinc layer on the surface of the pin, increasing the firmness of the surface of the pin, making the welding more stable, and promoting the movement of the pin under the drive of the grinding roller, thus preventing the pin from getting stuck on the surface of the strip-shaped grinding block. Moreover, the surface of the strip-shaped grinding block is obliquely provided with leakage holes to prevent the pin from getting stuck on the surface of the strip-shaped grinding block and guiding the ground debris for collection. The grinding of the surface of the pin and the collection of debris are realized, increasing the roughness of the surface of the pin, and thus facilitating the welding operation better.

[0007] Preferably, the welding device includes a welding bottom plate, on the top of which a welding bracket is fixedly connected.

When the stroke of the push plate reaches half, the second motor drives the push plate to move in the opposite direction, so as to drive the solder paste to flow from the inside of the first one-way valve and enter the inside of the extrusion housing. The remaining heat of the solder paste remaining in the extrusion housing is beneficial to the fusion of the newly added solder paste and the original solder paste, so as to keep the temperature uniform, which is beneficial to extrusion for welding. The limit housing cooperates with the solder paste hole through the shape of the bottom, so as to limit the downward amount of the first telescopic rod, so that there is a gap at the top of the demolding assembly, so as to leave space for the solder paste and the leads, so as to facilitate the shaping of the solder paste.

[0012] The present invention provides a pin welding device for LED lamp production. It has the following beneficial effects:

[0013] 1. For the pin welding device for LED lamp production, a grinding roller rotates to drive the pins to move on the surface of the strip-shaped grinding block, causing the pins to slide on the surface of the strip-shaped grinding block, thereby grinding the zinc layer on the surface of the pins, increasing the firmness of the pin surface, making the welding more stable, and promoting the movement of the pins under the drive of the grinding roller, thus preventing the pins from getting stuck on the surface of the strip-shaped grinding block. Moreover, the surface of the strip-shaped grinding block is inclined and provided with leakage holes to prevent the pins from getting stuck on the surface of the strip-shaped grinding block and guiding and collecting the grinding debris. The grinding of the pin surface and the collection of debris are realized, increasing the surface roughness of the pins, and thus enabling better welding operations.

[0014] 2. For the pin welding device for LED lamp production, an electric fan rotates to drive the air to flow. The air flows through the inside of the collection box, passes through the filter screen space and is discharged through the air outlet. The debris, under the action of gravity and air flow, passes through the inside of the collection box and is left inside the collection box through the screening action of the filter screen, thus collecting the debris after grinding. The collection of pin debris is realized.

[0015] 3. The pin welding device for LED lamp production is provided with the movable end of the first telescopic rod driving the downward pressing top plate to move. The solder paste raw material is put into the interior of the feed inlet and melted under the heating action of the electric heating tube, so that the solder paste becomes liquid. The downward movement of the downward pressing top plate drives the welding housing to move downward, and the downward movement of the welding housing drives the limiting housing to move downward. When the bottom of the limiting housing contacts the top of the stripping component, the second motor starts to drive the screw to rotate. The rotation of the screw drives the pushing plate to move. The solder paste reaches the interior of the extrusion housing through the first one-way valve under the one-way guiding action of the first one-way valve. During the movement of the pushing plate, the solder paste is extruded, so that the solder paste is extruded. The solder paste is extruded through the second one-way valve, so that the solder paste is extruded onto the top of the stripping component, so that the solder paste, pins and leads are mixed, and the shape of the solder paste is formed under the action of the stripping component, so that the welding position maintains a regular shape, improving the welding quality. When the stroke of the pushing plate reaches half, the second motor drives the pushing plate to move in the opposite direction, so as to drive the solder paste to flow from the interior of the first one-way valve and enter the interior of the extrusion housing. The remaining heat of the solder paste remaining in the extrusion housing is conducive to the fusion of the newly added solder paste and the original solder paste, so as to keep the temperature uniform, which is conducive to extrusion for welding. The limiting housing is matched with the solder paste hole through the shape of the bottom, so as to limit the downward displacement of the first telescopic rod, so that there is a gap at the top of the stripping component, so as to leave space for the solder paste and leads, so as to facilitate the shaping of the solder paste. The auxiliary support supports the extrusion housing, so that the force is evenly distributed during shaping, which is conducive to the cooling and leveling of the solder paste. The welding of pins and leads is realized, and the welding shape is flat. Moreover, the isolation and automatic filling of the solder paste are realized, thus simplifying the process of solder paste extrusion and replenishment, and making it easy to process.

[0016] 4. The pin welding device for LED lamp production is provided with air inside the air duct flowing under the drive of an electric fan, thereby cooling the water flow inside the loop-shaped cooling pipe. Moreover, the loop design of the loop-shaped cooling pipe increases the contact area between the loop-shaped cooling pipe and the air, thus increasing the cooling efficiency. When the solder paste is pressed down for shaping, the solder paste is on the top of the shaping plate and is concentrated at the center position of the shaping plate under the action of the guiding block. And the water flow passes through the inside of the cooling housing to cool the bottom of the shaping plate, so that the solder paste starts to be cooled from the bottom, thus performing shaping cooling and preferentially shaping the bottom of the solder paste, which is beneficial to the formation of the solder paste. During the descent of the limiting housing, the limiting housing squeezes the guiding block and drives the shaping plate to descend. The shaping plate drives the cooling housing to descend, and the descent of the cooling housing drives the spring telescopic rod to be compressed, generating an upward elastic force inside the spring telescopic rod, which applies pressure to the solder paste and the pin lead during shaping to keep the welding in place. The guiding block ensures there is space to avoid excessive extrusion. After the solder paste is cooled, the limiting housing moves upward, and the elastic force released by the spring telescopic rod drives the cooled solder paste to move, so that the welded part automatically disengages from the inside of the solder paste hole, completing the process of automatic material removal.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 - Figure 2 , the present invention provides a technical solution: A pin welding device for LED lamp production, including a bottom plate bracket 1, a grinding device 2 is fixedly connected to the top of the bottom plate bracket 1, a welding device 3 is fixedly connected to the side of the grinding device 2, and the bottom of the welding device 3 is fixedly connected to the top of the bottom plate bracket 1.

[0029] The bottom plate bracket 1 supports the whole device. The grinding device 2 grinds the pins to increase the roughness. Considering that most pins are made of iron-based galvanized material, when welding, the solder paste will detach from the surface of the pins, resulting in insecure lead welding. Slight grinding can remove the zinc layer on the surface of the pins, thus increasing the adhesion between the pins and the solder paste, making the connection between the pin leads and the solder paste firm, and the welding device 3 melts and keeps the solder paste warm, and solidifies the solder paste by water cooling, so as to form the welding, preventing deformation when the solder paste is not solidified and affecting the welding quality.

[0030] The grinding device 2 includes a grinding bottom plate 201. A grinding bracket 202 is fixedly connected to the side of the grinding bottom plate 201. A first motor 203 is fixedly connected to the side of the grinding bracket 202. The driving shaft of the first motor 203 penetrates the side of the grinding bracket 202 and is rotatably connected to the grinding bracket 202. A grinding roller 204 is fixedly connected to the driving shaft of the first motor 203. A strip-shaped grinding block 205 is fixedly connected to the side of the grinding bottom plate 201. A debris collection device 206 is fixedly connected to the bottom of the strip-shaped grinding block 205. The top of the strip-shaped grinding block 205 contacts the side of the grinding roller 204. The bottom of the grinding bottom plate 201 is fixedly connected to the top of the bottom plate bracket 1.

[0031] When the pins pass between the grinding roller 204 and the strip-shaped grinding block 205, start the first motor 203. The driving shaft of the first motor 203 drives the grinding roller 204 to rotate. The rotation of the grinding roller 204 drives the pins to move on the surface of the strip-shaped grinding block 205, making the pins slide on the surface of the strip-shaped grinding block 205, so as to grind the zinc layer on the surface of the pins, increasing the firmness of the pin surface, making the welding more stable, and promoting the movement of the pins under the drive of the grinding roller 204, thus preventing the pins from getting stuck on the surface of the strip-shaped grinding block 205. And the surface of the strip-shaped grinding block 205 is inclined and provided with leakage holes to prevent the pins from getting stuck on the surface of the strip-shaped grinding block 205 and guiding and collecting the ground debris. The grinding of the pin surface and the collection of debris are realized, increasing the roughness of the pin surface and thus better performing the welding operation.

[0032] Please refer to Figure 1 - Figure 3, the present invention provides a technical solution: The debris collection device 206 includes a collection housing 2061. A first slide bar 2062 is fixedly connected to the inner wall side of the collection housing 2061. A collection box 2063 is slidably connected to the inner wall of the collection housing 2061. A chute adapted to the first slide bar 2062 is provided on the side of the collection box 2063. The collection box 2063 is slidably connected to the collection housing 2061 through the first slide bar 2062.

The top of the collection housing 2061 is fixedly connected to the bottom of the strip-shaped grinding block 205. The bottom of the collection housing 2061 is fixedly connected to the top of the bottom plate bracket 1.

[0033] After the pins are polished, start the electric fan 2064. The rotation of the electric fan 2064 drives the air to flow. The air flows from the inside of the collection box 2063, passes through the space of the filter screen 2066 and is discharged through the air outlet 2065. The debris, under the action of gravity and air flow, passes through the inside of the collection box 2063 and is screened by the filter screen 2066, so that the debris is left inside the collection box 2063, thereby collecting the debris after polishing. The collection of pin debris is realized.

The bottom of the auxiliary support 30466 is fixedly connected to the bottom inner wall of the limiting housing 3048. The top of the extrusion housing 30461 is fixedly connected to the bottom of the inlet 3042.

[0037] When welding, the pins and leads are placed inside the solder paste holes 305 and are limited in position under the action of the wire positioning block 306. The movable end of the first telescopic rod 303 drives the downward pressing top plate 3043 to move. The solder paste raw material is put into the inside of the feed port 3042 and is melted under the heating action of the electric heating tube 3047, so that the solder paste becomes liquid. The downward movement of the downward pressing top plate 3043 drives the welding housing 3041 to move downward, and the downward movement of the welding housing 3041 drives the limiting housing 3048 to move downward. When the bottom of the limiting housing 3048 contacts the top of the stripping assembly 307, the second motor 30462 starts to drive the screw-in screw 30463 to rotate.

The solder paste reaches the inside of the extrusion housing 30461 through the first one-way valve 3044 under the one-way guiding action of the first one-way valve 3044. During the movement of the pushing plate 30464, the solder paste is extruded, so that the solder paste is extruded. The solder paste is extruded through the second one-way valve 30465, so that the solder paste is extruded onto the top of the stripping assembly 307, so that the solder paste, pins and leads are mixed, and the shape of the solder paste is formed under the action of the stripping assembly 307, so that the welding position maintains a regular shape and the welding quality is improved. When the stroke of the pushing plate 30464 reaches half, the second motor 30462 drives the pushing plate 30464 to move in the opposite direction, so as to drive the solder paste to flow from the inside of the first one-way valve 3044 and enter the inside of the extrusion housing 30461. The remaining heat of the solder paste remaining inside the extrusion housing 30461 is beneficial to the fusion of the newly added solder paste and the original solder paste, so as to keep the temperature uniform, which is beneficial to extrusion for welding. The limiting housing 3048 cooperates with the solder paste holes 305 through the shape of the bottom, so as to limit the downward movement amount of the first telescopic rod 303, so that there is a gap at the top of the stripping assembly 307, so as to leave space for the solder paste and leads, so as to facilitate the shaping of the solder paste. The auxiliary support 30466 supports the extrusion housing 30461, so that the force is uniform during shaping, which is beneficial to the cooling and flattening of the solder paste. The welding of the pins and leads is realized, and the welding shape is flat, and the isolation and automatic filling of the solder paste are realized, so as to simplify the process of solder paste extrusion and replenishment, and thus it is easy to process.

The air inside the air duct 3086 flows driven by the electric fan 2064, thereby cooling the water flow inside the loop-shaped cooling pipe 3081. And through the loop design of the loop-shaped cooling pipe 3081, the contact area between the loop-shaped cooling pipe 3081 and the air is increased, thereby increasing the cooling efficiency. When the solder paste is pressed and shaped, the solder paste is on the top of the shaping plate 3072 and is concentrated at the center position of the shaping plate 3072 under the action of the guiding block 3073. And the water flow passes through the inside of the cooling housing 3071 to cool the bottom of the shaping plate 3072, so that the solder paste starts to be cooled from the bottom, thereby performing shaping cooling and preferentially shaping the bottom of the solder paste, which is beneficial to the forming of the solder paste. During the downward movement of the limiting housing 3048, the limiting housing 3048 squeezes the guiding block 3073 and drives the shaping plate 3072 to descend. The shaping plate 3072 drives the cooling housing 3071 to descend. The downward movement of the cooling housing 3071 drives the spring telescopic rod 3077 to be compressed, generating an upward elastic force inside the spring telescopic rod 3077 to apply pressure to the solder paste and the pin leads during shaping to keep the welding in place. The guiding block 3073 ensures that there is space to avoid excessive extrusion. After the solder paste is cooled, the limiting housing 3048 moves upward, and the elastic force released by the spring telescopic rod 3077 drives the cooled solder paste to move, so that the welded part automatically exits from the inside of the solder paste hole 305, completing the process of automatic material removal.
