Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a molten droplet welding device with a fixed tin wire path. Background Technology

[0002] Chinese Patent CN211162284U discloses a quantitative melting droplet soldering robot with solder wire storage, which includes a base and a solder conveying assembly. The solder conveying assembly has a material dropping channel and a sliding hole connected to the material dropping channel. A horizontally movable baffle plate and a baffle power device connected to the baffle plate are arranged in the sliding hole. A longitudinally movable shearing rod is arranged in the material dropping channel. A drive wheel and a driven wheel are rotatably connected on the base. The two wheels clamp the solder wire and convey the solder wire horizontally. The working principle is as follows: the drive wheel and the driven wheel send the solder wire into the material dropping channel a certain distance. Then the shearing rod moves down to cut the horizontal solder wire into small pieces of solder wire, which fall and stay on the baffle plate. When the number of small pieces of solder wire staying on the baffle plate reaches a preset number, the baffle cylinder drives the baffle plate to move to open the material dropping channel.

[0003] However, when the shearing rod cuts the solder wire, the wire is horizontal. Then, it flips during the fall. The different postures of the multiple solder wire segments during the fall cause instability in the falling process, which can lead to jamming and other problems. Furthermore, due to the diameter limitation of the feeding channel, the length of the short solder wire segments is relatively short. Therefore, multiple cutting is required to improve efficiency. The increase in the number of cuttings leads to more residue and the flux in the center of the solder wire falls out. This causes the flux and residue to stick to the solder feeding channel, affecting stability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that in the prior art, when the solder wire is fed horizontally, it will flip during the falling process, and the different postures of multiple solder wires during the falling process will lead to instability and jamming. The present invention provides a solder wire path fixed droplet soldering device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a solder wire path fixed droplet soldering device, comprising:

[0006] A welding assembly, including a welding nozzle and a wire drop channel communicating with the welding nozzle;

[0007] The wire feeding assembly has a wire feeding channel;

[0008] The wire cutting assembly is located between the wire feeding assembly and the welding assembly. It includes a stationary blade holder, a moving blade holder, and a shearing power mechanism for driving the moving blade holder to reciprocate between a first position and a second position. When the moving blade holder is in the first position, the wire cutting assembly forms a wire cutting channel that communicates with the wire feeding channel. During the movement of the moving blade holder from the first position to the second position, the wire cutting assembly cuts the solder wire in the wire cutting channel. When the moving blade holder moves to the second position, the wire cutting assembly forms a wire blowing channel that communicates with the wire dropping channel to blow the cut segmented solder wire into the wire dropping channel.

[0009] Furthermore, a moving groove is formed inside the moving tool holder;

[0010] The upper part of the stationary knife holder has a wire inlet and an upper air blowing port located on the moving groove's movement path, and the lower part has a transition hole located on the moving groove's movement path and connected to the wire dropping channel. The wire inlet and the moving groove are connected to form the aforementioned wire cutting channel, and the upper air blowing port, the moving groove, and the transition hole are sequentially connected to form the aforementioned wire blowing channel.

[0011] Furthermore, the moving blade holder includes a moving blade body and a material box fixed to the bottom of the moving blade body, and the stationary blade holder includes a stationary blade body that cooperates with the moving blade body and a base fixed to the bottom of the stationary blade body. A first sliding groove for the moving blade body to slide is formed between the stationary blade body and the base.

[0012] Furthermore, the stationary knife hole on the stationary knife body, the moving knife hole on the moving knife body, and the material storage hole on the material box are all connected by a chamfered transition.

[0013] Furthermore, it also includes a connecting plate fixed between the welding assembly and the wire cutting assembly, and a lifting mechanism for driving the connecting plate to rise and fall.

[0014] Furthermore, the stationary knife holder is also provided with a downward air blowing port that communicates with the wire dropping channel.

[0015] Furthermore, the stationary knife holder also includes an upper seat fixed above the seat body and a lower seat fixed below the seat body. The lower seat has a second sliding groove for sliding the feed box and extends to form a support portion for supporting the shearing power mechanism.

[0016] Furthermore, the wire feeding assembly includes a rotary drive mechanism, a drive wheel connected to the output end of the rotary drive mechanism, and a driven wheel disposed opposite to the drive wheel, wherein the drive wheel and the driven wheel clamp the solder wire.

[0017] Furthermore, the wire feeding assembly also includes an adjustment mechanism for moving the driven wheel closer to or away from the driving wheel.

[0018] Furthermore, the adjustment mechanism includes:

[0019] A swing arm, with a swinging mechanism and the aforementioned driven wheel mounted thereon;

[0020] A positioning sleeve is fitted outside the wire feeding channel;

[0021] An adjusting screw, which passes through the rocker arm and whose head is abutted by the positioning sleeve, adjusts the distance between the driven wheel and the driving wheel during its rotation;

[0022] And a positioning elastic element, which is disposed between the rocker arm and the positioning sleeve to provide clamping force for the driven wheel.

[0023] The beneficial effects of this invention are as follows: This invention uses a laterally moving blade holder to cut the longitudinally input solder wire. The solder wire maintains its original vertical posture and enters the solder nozzle from the wire drop channel. The solder wire posture is fixed during the wire feeding and cutting process, eliminating the need for flipping and preventing jamming. At the same time, the solder wire is transported longitudinally, increasing the length of the segmented solder wire, which reduces the number of cutting operations and the amount of residue and flux falling out during the cutting process. Furthermore, the air blowing channel helps to blow away the solder wire, residue, and flux, further preventing blockage. Attached Figure Description

[0042] The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner. Therefore, they only show the components relevant to the invention, and the orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be limiting, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0043] like Figures 1-3 As shown, a fixed-path molten droplet soldering device includes a soldering assembly 1, a wire feeding assembly 2, and a wire cutting assembly 3.

[0044] The welding assembly 1 includes a welding nozzle 101, a wire drop channel 102 communicating with the welding nozzle 101, and a heating element 6 for heating and melting the solder wire in the wire drop channel 102. The heating element 6 can be a heating tube that is sleeved on the outside of the wire drop channel 102. The wire drop channel 102 is vertically arranged and located above the welding nozzle 101. The solder wire in the wire drop channel 102 can enter the welding nozzle 101 under the action of gravity, and the heating element 6 melts the solder wire during the falling process and sprays it out from the welding nozzle 101 for welding.

[0045] The wire feeding assembly 2 has a wire feeding channel 201, which can be a telescopic tube;

[0046] And the wire cutting assembly 3, which is located between the wire feeding assembly 2 and the welding assembly 1, includes a stationary knife holder 301, a moving knife holder 302 and a shearing power mechanism 303 for driving the moving knife holder 302 to reciprocate between a first position and a second position. The shearing power mechanism 303 can be, but is not limited to, a cylinder, an electric cylinder, etc. During the lateral movement of the moving knife holder 302, a lateral displacement occurs between it and the stationary knife holder 301 to generate a shearing force on the solder wire located between the two, thereby cutting it into segmented solder wires.

[0047] like Figure 4 As shown, when the moving blade holder 302 is in the first position, a cutting channel communicating with the wire feeding channel 201 is formed inside the wire cutting assembly 3. At this time, the solder wire enters the cutting channel from the wire feeding channel 201, and during the movement of the moving blade holder 302 from the first position to the second position, the solder wire in the cutting channel is cut to form segmented solder wire, such as... Figure 5 As shown, when the moving blade holder 302 moves to the second position, the wire cutting assembly 3 has a blowing channel inside for communicating with the wire dropping channel 102 to blow the cut segmented solder wire into the wire dropping channel 102. The airflow enters the blowing channel and blows the segmented solder wire into the wire dropping channel 102. The wire feeding channel 201 and the wire dropping channel 102 are both vertically arranged and are offset in the horizontal direction. The first position corresponds to the position of the wire feeding channel 201 and the second position corresponds to the position of the wire dropping channel 102.

[0048] This application uses a laterally moving blade holder 302 to cut the longitudinally input solder wire. The solder wire maintains its original vertical posture and enters the solder nozzle 101 from the wire drop channel 102. The solder wire posture is fixed during the wire feeding and cutting process, and there is no need to flip it, which can avoid jamming. At the same time, the solder wire is transported longitudinally, and the length of the segmented solder wire is increased, which can reduce the number of cuttings and reduce the drop of residue and flux generated during the cutting process. Furthermore, the air blowing channel helps to blow away the solder wire, residue and flux, further preventing blockage.

[0049] In some examples, such as Figures 8-10 As shown, a moving groove 302a is formed inside the moving tool holder 302;

[0050] The upper part of the stationary knife holder 301 has a wire inlet 301a and an upper air outlet 301b located on the movement path of the moving groove 302a. The two are arranged side by side in the transverse direction. The lower part has a transition hole 301c located on the movement path of the moving groove 302a and connected to the wire drop channel 102. When the moving groove 302a moves to the first position, the wire inlet 301a and the moving groove 302a are connected to form the above-mentioned wire cutting channel. The solder wire can enter the wire cutting channel from the wire feeding channel 201. When the moving groove 302a moves to the second position, the upper air outlet 301b, the moving groove 302a and the transition hole 301c are connected in sequence to form the above-mentioned wire blowing channel. The upper air outlet 301b, the moving groove 302a and the transition hole 301c are chamfered to transition between them. The wire inlet 301a and the moving groove 302a are also chamfered to transition between them.

[0051] In some examples, such as Figures 8-10 As shown, the moving blade holder 302 includes a moving blade body 3021 and a material box 3022 fixed to the bottom of the moving blade body 3021. That is, the material box 3022 of this application is integrated into the shredding assembly 3, and the cutting and storage are integrated, which simplifies the equipment structure and reduces the cost.

[0052] When the moving blade holder 302 moves to the first position, the wire inlet 301a at the top of the stationary blade holder 301 connects with the moving groove 302a, while the bottom of the stationary blade holder 301 blocks the bottom of the moving groove 302a, i.e., the bottom of the material box 3022 is blocked. The solder wire enters the wire cutting channel and is cut into segments as the moving blade holder 302 moves to the second position. The segments can be stored in the material box 3022. At this time, the shearing power mechanism 303 can drive the moving blade holder 302 to move to the second position so that the segment of solder wire directly enters the wire dropping channel 102, or the moving blade holder 302 can be directly reset to the first position, and the solder wire can continue to enter the moving groove 302a for recutting. Multiple segments of solder wire after multiple cuts can be stored in the material box 3022, and after the moving blade holder 302 moves to the second position, multiple segments of solder wire simultaneously enter the wire dropping channel 102. The height of the material box 3022 is much greater than the height of the moving blade body 3021.

[0053] The stationary blade holder 301 includes a stationary blade body 3011 that cooperates with the moving blade body 3021 and a base 3012 fixed to the bottom of the stationary blade body 3011. A first sliding groove 3013 for sliding of the moving blade body 3021 is formed between the stationary blade body 3011 and the base 3012. The thickness of the stationary blade body 3011 is much smaller than the thickness of the base 3012. The small thickness of the stationary blade body 3011 and the small thickness of the moving blade body 3021 can improve the flatness of both, reduce the friction between them, and reduce the deformation of the longitudinally entering solder wire during the cutting process.

[0054] In some examples, such as Figure 4 and Figure 5As shown, the stationary knife hole 3011a on the stationary knife body 3011, the moving knife hole 3021a on the moving knife body 3021, and the storage hole 3022a on the material box 3022 are longitudinally distributed, and the adjacent ones are all chamfered transitions with an angle of 30°. This adds a guiding measure between the adjacent ones, which can solve the problem of the two having different axes, ensuring that the solder wire can fall smoothly. In order to further prevent clogging, the diameter of the stationary knife hole 3011a, the moving knife hole 3021a, and the storage hole 3022a can be increased sequentially. The stationary knife hole 3011a forms part of the wire inlet 301a.

[0055] In some examples, such as Figure 6 and Figure 7 As shown, it also includes a connecting plate 4 fixed between the welding assembly 1 and the wire cutting assembly 3, and a lifting power mechanism for driving the connecting plate 4 to rise and fall. Therefore, the lifting power mechanism can drive the welding assembly 1 and the wire cutting assembly 3 to rise and fall synchronously through the connecting plate 4 to form an overall lifting structure. This eliminates the silicone buffer pad used for sealing between the welding assembly 1 and the wire cutting assembly 3 when the welding assembly 1 rises and falls independently in the traditional structure, making the equipment simpler, reducing cost and complexity, and avoiding the pressure brought by the structure, thereby reducing the contact force between the welding nozzle 101 and the welded part.

[0056] The lifting power mechanism includes a lifting power component installed inside the housing 5. The output end of the lifting power component is connected to the connecting plate 4. A slider-rail combination is provided between the connecting plate 4 and the housing 5 to guide its movement direction. At the same time, a guide post 401 is protruding from the connecting plate 4. A guide groove 501 is provided on the housing 5 for the guide post 401 to slide. The combination of the slider-rail combination and the guide post combination together ensures the movement accuracy of the welding assembly 1 and the wire cutting assembly 3.

[0057] In some examples, such as Figure 4 and Figure 5 As shown, the stationary knife holder 301 is also provided with a downward air blowing port 301d that communicates with the wire falling channel 102. The downward air blowing port 301d is located below the upward air blowing port 301b. On the one hand, it blows the segmented solder wire in the wire falling channel 102 so that it falls smoothly. On the other hand, it can blow the liquid droplets formed after the solder wire is melted out of the soldering nozzle 101 for soldering.

[0058] In some examples, such as Figure 10 As shown, the stationary knife holder 301 also includes an upper seat 3014 fixed above the seat body 3012 and a lower seat 3015 fixed below the seat body 3012. After the stationary knife body 3011 is embedded in the seat body 3012, the upper seat 3014 and the lower seat 3015 are fixed to clamp the stationary knife body 3011 and the seat body 3012 between them. A limiting structure is provided between the stationary knife body 3011 and the seat body 3012 to prevent the stationary knife body 3011 from moving laterally.

[0059] The lower seat 3015 has a second sliding groove 3015a for sliding the feeding box 3022, and the lower seat 3015 extends to form a support part 3015b for supporting the shearing power mechanism 303. The shearing power mechanism 303 is fixed on the support part 3015b. The two side walls of the second sliding groove 3015a can limit the movement position of the feeding box 3022. The bottom of the second sliding groove 3015a is used to block or open the moving groove 302a. The top of the second sliding groove 3015a is always blocked by the moving blade body 3021 to prevent impurities from entering.

[0060] In some examples, such as Figure 6 and Figure 7 As shown, the wire feeding assembly 2 includes a rotary drive mechanism 202, a drive wheel 203 connected to the output end of the rotary drive mechanism 202, and a driven wheel 204 disposed opposite to the drive wheel 203. The drive wheel 203 and the driven wheel 204 clamp the solder wire. The rotary drive mechanism 202 can be a stepper motor. After the solder wire passes between the drive wheel 203 and the driven wheel 204, the rotary drive mechanism 202 drives the drive wheel 203 to rotate, thereby conveying the solder wire toward the wire cutting assembly 3.

[0061] In some examples, such as Figure 1 and Figure 2 As shown, the wire feeding assembly 2 also includes an adjustment mechanism for driving the driven wheel 204 closer to or further away from the driving wheel 203, so that the distance between the driving wheel 203 and the driven wheel 204 can be adjusted according to the diameter of the solder wire and the magnitude of the clamping force.

[0062] In some examples, the adjustment mechanism includes:

[0063] The swing arm 205 is swing-mounted and the driven wheel 204 is mounted on it. One end of the swing arm is hinged to the housing 5, and a support arm is formed by the protrusion in the middle. The driven wheel 204 is rotatably mounted on the support arm.

[0064] The positioning sleeve 206 is fixed on the housing 5 and sleeved on the outside of the wire feeding channel 201;

[0065] The adjusting screw 207 passes through the rocker arm 205 and its head abuts against the positioning sleeve 206 to adjust the distance between the driven wheel 204 and the driving wheel 203 during its rotation. The side of the positioning sleeve 206 facing the adjusting screw 207 is its positioning surface, which is preferably a plane. After the head of the adjusting screw 207 abuts against the positioning surface, rotating the adjusting screw 207 can drive the rocker arm 205 to move closer to or away from the positioning sleeve 206, thereby driving the driven wheel 204 to move closer to or away from the driving wheel 203.

[0066] A positioning elastic element is provided between the rocker arm 205 and the positioning sleeve 206 to provide clamping force to the driven wheel 204. The minimum distance between the driving wheel 203 and the driven wheel 204 can be limited by adjusting the screw 207. It can only prevent the driven wheel 204 from continuing to approach the driving wheel 203, but cannot prevent the driven wheel 204 from moving away from the driving wheel 203. The positioning elastic element can be a spring, which pulls the rocker arm 205, thereby preventing the driven wheel 204 from moving away from the driving wheel 203, so that the driving wheel 203 and the driven wheel 204 can provide sufficient clamping force to the solder wire. In a specific implementation, screws are installed on both the rocker arm 205 and the positioning sleeve 206, and the two ends of the positioning elastic element are respectively sleeved on the two screws.

[0067] Working principle:

[0068] First, the shearing power mechanism 303 drives the moving blade holder 302 to the first position. At this time, the moving groove 302a is aligned with the wire inlet 301a to form a wire cutting channel.

[0069] Then start the rotary drive mechanism 202 to transport the solder wire in the wire feeding channel 201 to the wire cutting channel;

[0070] Next, the shearing power mechanism 303 drives the moving blade holder 302 to move to the second position. During the movement, the moving groove 302a is misaligned with the wire inlet 301a to cut the solder wire and form segmented solder wire.

[0071] Then the shearing power mechanism 303 drives the moving knife holder 302 to the second position. At this time, the upper air blowing port 301b, the moving groove 302a and the transition hole 301c are connected in sequence to form an air blowing channel. The segmented tin wire in the moving groove 302a enters the wire dropping channel 102 under its own gravity and the blowing of the airflow from the upper air blowing port 301b.

[0072] Finally, the segmented solder wire in the wire drop channel 102 falls off under its own gravity and the blowing of the airflow entering from the bottom air outlet 301d. The heating element 6 heats and melts the segmented solder wire during its fall, and the airflow entering from the bottom air outlet 301d blows out the molten droplets for soldering.

[0073] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
