Description

Metal wire flattening, forming, conveying and pelletizing equipment Technical Field

[0001] The present application relates to the field of metal wire processing, and in particular to metal wire flattening, forming and pelletizing equipment. Background Art

[0002] Tin particles and other materials are often used as conductors for connection between electronic components, and the connection is generally achieved by melt welding. The size of tin particles is usually very small, and the tin bars need to be cut into individual tin particles during processing. In the prior art, metal pelletizing equipment is used to produce tin particles, which generally includes a discharge mechanism at the rear end and a conveying and pelletizing mechanism at the front end. The current discharge mechanism is far away from the conveying and pelletizing mechanism, and the tin bars are thin and soft. When conveyed forward, there is a risk of bending and folding, which leads to blockage. In addition, in order to realize automatic unloading, a material-retrieving robot is provided above the conveying and pelletizing mechanism. After the conveying and pelletizing mechanism cuts out the tin particles, the material-retrieving robot is triggered to take away the tin particles. However, it is easy to be triggered incorrectly, causing the robot to mistakenly take the tin particles.

[0003] Therefore, there is an urgent need to provide a metal wire flattening, forming and conveying pelletizing equipment that is less likely to cause bending and blocking during metal wire conveying to overcome the above-mentioned defects.

[0048] In order to explain the technical content and structural features of the present application in detail, the following further describes the embodiments in conjunction with the accompanying drawings.

[0049] As shown in Figures 1 to 8, the present application provides a metal wire flattening, forming, conveying and pelletizing device 1000, which is used to cut metal wire into small metal pellets. The metal pellets are generally small in size and are generally tin pellets, but can also be copper pellets. The tin pellets are used as conductors between electronic components, achieving electrical connections between the electronic components through melting. It is easy to understand that because tin is relatively soft and has a small diameter, it is prone to bending during conveyance, resulting in material blockage. The present application is intended to solve this problem.

[0050] The metal wire flattening, forming, conveying and pelletizing apparatus 1000 of the present application includes a flattening and discharging mechanism 100 located at the rear end and a conveying and pelletizing mechanism 200 located at the front end. The flattening and discharging mechanism 100 is used to discharge the flattened metal wire horizontally to the conveying and pelletizing mechanism 200. The conveying and pelletizing mechanism 200 is used to convey the metal wire forward and pelletize it. The flattening and discharging mechanism 100 includes a flattening wheel assembly 10, a rotatable member 20, a photoelectric sensor 30, and an output guide wheel 40. The flattening wheel assembly 10, the rotatable member 20, and the output guide wheel 40 are arranged in sequence from back to front. The rotatable member 20 is arranged in a rotating manner. The first end of the rotatable member 20 is adjacent to the flattening wheel assembly 10, and an input guide wheel 50 is mounted on the first end of the rotatable member 20. The photoelectric sensor 30 is aligned with the second end of the rotatable member 20. The metal wire discharged from the flattening wheel assembly 10 passes through the input guide wheel 50 and the output guide wheel 40 in sequence before entering the conveying and pelletizing mechanism 200. When the pelletizing mechanism 200 drives the metal wire forward, the oscillating member 20 is pressed and rotated, causing its second end to deviate from the photoelectric sensor 30, causing the photoelectric sensor 30 to be triggered, thereby driving the flattening wheel assembly 10 to flatten the metal wire and output it.

[0051] In the present application, a swivel member 20 and an output guide wheel 40 are added to the flattening wheel assembly 10 and the conveying and pelletizing mechanism 200. The section of metal wire located between the flattening wheel assembly 10 and the conveying and pelletizing mechanism 200 is supported and limited by the input guide wheel 50 and the output guide wheel 40, thereby limiting the floating and twisting of the metal wire. The metal wire discharged from the output guide wheel 40 is straight, without twisting or bending, solving the problem of material blockage caused by twisting and bending when the metal wire is conveyed forward. In addition, after the swivel member 20 and the output guide wheel 40 are added, the flattening and discharging mechanism 100 and the conveying and pelletizing mechanism 200 can be very close, which is conducive to achieving a compact layout of the metal wire flattening, forming and conveying and pelletizing equipment 1000.

[0052] It should be noted that when the conveying and pelletizing mechanism 200 conveys the metal wire forward, the conveying distance is the length of the tin particles to be cut out, so the feed length of the metal wire is very short. Because the feed amount of the metal wire is not large, it is equivalent to "tightening" the wire, which causes the input guide wheel 50 to be compressed, causing the swing member 20 to rotate. The swing member 20 rotates so that its second end deviates from the photoelectric sensor 30. The photoelectric sensor 30 is triggered to control the flattening wheel group 10 to flatten the metal wire and then release it. This process takes a very short time, about 0.04s. This process shows that when the conveying and pelletizing mechanism 200 conveys the metal wire forward, the flattening wheel group 10 can replenish the metal wire in time.

[0053] As shown in Figures 1 to 6, the swing member 20 is a bent structure. The swing member 20 includes a first part 21 and a second part 22. The first part 21 is placed horizontally, and the second part 22 is tilted upward. The swing member 20 is rotatably mounted on the frame 300 at the connection between the first part 21 and the second part 22. The input guide wheel 50 is rotatably mounted on the end of the second part 22, and the photoelectric sensor 30 is aligned with the end of the first part 21. The swing member 20 is set to bend, and when the input guide wheel 50 is pressurized, it can immediately cause the swing member 20 to rotate, thereby quickly triggering the photoelectric sensor 30. Preferably, the photoelectric sensor 30 is a slot-type photoelectric switch having a detection opening 31. A protrusion structure 23 protrudes from the end of the first part 21, and the protrusion structure 23 is inserted into the detection opening 31. When the protrusion structure 23 is inserted into the detection opening 31 , the slot-type photoelectric switch is not triggered. However, when the protrusion structure 23 leaves the detection opening 31 , the slot-type photoelectric switch is immediately triggered. The photoelectric sensor 30 determines whether the swinging member 20 rotates by detecting whether the protrusion structure 23 is in the detection opening 31 .

[0054] Furthermore, an elastic member 60 is mounted between the second portion 22 and the frame 300. This elastic member 60 constantly tends to rotate the second portion 22 upward, thereby restoring the pivoting member 20 after rotation. To enhance the mounting stability of the elastic member 60, it is positioned below the second portion 22. The second portion 22 defines a mounting hole 24, into which the top portion of the elastic member 60 extends.

[0055] As shown in Figures 1 to 6, the flattening and unloading mechanism 100 also includes a guide rod 70. The guide rod 70 is arranged above the swing member 20. The guide rod 70 is arranged between the input guide wheel 50 and the output guide wheel 40. The metal wire output by the flattening wheel group 10 passes around the input guide wheel 50 upwards, then passes around the guide rod 70 downwards, and then passes around the output guide wheel 40 upwards. The guide rod 70 limits the upward deviation of the metal wire and, to a certain extent, avoids possible twisting and bending of the metal wire. The guide rod 70 is located directly above the connection between the first part 21 and the second part 22, and the guide rod 70 is located below the line connecting the input guide wheel 50 and the output guide wheel 40. The guide rod 70 serves to amplify the movement of the metal wire.

[0056] The input guide wheel 40 and the output guide wheel 50 are each provided with a slot (not shown) for the metal wire to be inserted into. After the metal wire is inserted into the slot, the deviation of the metal wire in the left and right directions is limited, thereby preventing the metal wire from twisting and bending caused by the deviation.

[0057] As shown in Figures 1 to 6, the flattening wheel assembly 10 includes a driver 11, an upper pressing wheel 12, and a lower pressing wheel 13. The upper pressing wheel 12 is located directly above the lower pressing wheel 13 and the two are close to each other. The driver 11 drives one of the upper pressing wheel 12 and the lower pressing wheel 13 to rotate, and the other of the upper pressing wheel 12 and the lower pressing wheel 13 to rotate, and the metal wire passes between the upper pressing wheel 12 and the lower pressing wheel 13. The metal wire is flattened by the upper pressing wheel 12 and the lower pressing wheel 13 during the process of passing through the upper pressing wheel 12 and the lower pressing wheel 13. In this application, the driver 11 drives the lower pressing wheel 13 to rotate and thereby drives the upper pressing wheel 12 to rotate, but according to the change of the actual structural layout, the driver 11 can also drive the upper pressing wheel 12 to rotate and thereby drive the lower pressing wheel 13 to rotate. The rear end of the flattening wheel assembly 10 is placed with a metal coil, and the metal coil releases the metal wire through the upper pressing wheel 12 and the lower pressing wheel 13.

[0058] Furthermore, the output end of the driver 11 is connected to a worm 14, and a worm gear 15 is installed on one side of the lower pressure wheel 13. The worm gear 15 and the worm gear 14 cooperate to transmit power. A lower gear 16 is installed on the other side of the lower pressure wheel 13, and an upper gear 17 is installed on one side of the upper pressure wheel 12. The upper gear 17 and the lower gear 16 mesh with each other to transmit power. After the upper gear 17 and the lower gear 16 mesh, the transmission connection between the upper and lower pressure wheels 12 and 13 is achieved. The driver 11 drives the lower pressure wheel 13 to rotate through the worm gear transmission, which in turn drives the upper pressure wheel 12 to rotate.

[0059] Preferably, the diameters of the upper pressing wheel 12 and the lower pressing wheel 13 are equal, and the linear speeds of the upper pressing wheel 12 and the lower pressing wheel 13 are equal, so that the metal wire can be evenly flattened. The upper pressing wheel 12 is provided with a circle of upper pressing grooves (not marked), and the lower pressing wheel 13 is provided with a circle of lower pressing grooves (not marked). The metal wire is clamped into the upper and lower pressing grooves and flattened, ensuring the shaping effect.

[0060] As shown in FIG20 , the metal wire flattening, forming, conveying and pelletizing apparatus 1000 of the present application further includes a taker 400 disposed above the conveying and pelletizing mechanism 200. The taker 400 is used to remove the cut tin pellets by vacuum suction. Alternatively, the taker 400 can be clamped to remove the pellets as needed.

[0061] As shown in Figures 1 to 4 and Figures 7 to 19, the conveying and pelletizing mechanism 200 of the present application includes a conveying device 01, a positioning and cutting device 02, and a photoelectric sensor 03. The conveying device 01 feeds the clamped metal wire into the positioning and cutting device 02 in sections from front to back. The positioning and cutting device 02 cuts the metal wire fed into it to obtain metal pellets. The photoelectric sensor 03 is located above the conveying device 01 and the positioning and cutting device 02. The material picker 400 is located directly above the positioning and cutting device 02. The photoelectric sensor 03 is triggered when it sucks the metal pellets downward, thereby linking the positioning and cutting device 02 to cut the metal wire into metal pellets. The material picker 400 then removes the metal pellets upward.

[0062] In this application, a photoelectric sensor 03 is provided above the conveying device 01 and the positioning and cutting device 02. The photoelectric sensor 03 is used to detect the movement of the material picker 400, rather than detecting the metal pellets. The photoelectric sensor 03 is triggered when the material picker 400 moves downward, indicating that the material picker 400 is performing the action of taking away the metal pellets. The photoelectric sensor 03 links the positioning and cutting device 02 to cut out the metal pellets. After that, the material picker 400 takes away the metal pellets, and the conveying device 01 clamps the metal wire and feeds it forward. This processing method effectively avoids false sensing that causes the conveying device 01 to mistakenly feed the metal wire forward. Moreover, after the positioning and cutting device 02 cuts out the metal pellets, the metal pellets are immediately taken away by the material picker 400 and will not pop out. There is no need to add a structure to prevent the metal pellets from popping out, which is conducive to optimizing the structure.

[0063] As shown in Figures 1 to 4 and 7 to 19, a first channel 011 is defined at the top of the conveying device 01, and a second channel 021 is defined at the top of the positioning and cutting device 02. The first channel 011 and the second channel 021 are directly connected, and the photoelectric sensor 03 is aligned with the first channel 011 and the second channel 021. When the material picker 400 moves downward to remove the metal pellets, it must pass through the first channel 011 and the second channel 021, thereby triggering the photoelectric sensor 03.

[0064] Specifically, the photoelectric sensor 03 includes a receiver 031 located behind the conveyor 01 and a transmitter 032 located in front of the positioning and cutting device 02. However, depending on actual needs or conventional technical means in the art, the receiver 031 can be located in front of the positioning and cutting device 02, and the transmitter 032 can be located behind the conveyor 01.

[0065] Among them, in the embodiment provided in the present application, the transmitter 032 is aligned with the second channel 021, and the receiver 031 is aligned with the first channel 011. It is easy to understand that when the material picker 400 moves downward over the first channel 011 and the second channel 021, the communication between the transmitter 032 and the receiver 031 is blocked by the material picker 400, thereby triggering the photoelectric sensor 03.

[0066] As shown in Figures 1 to 4 and Figures 7 to 19, the conveying and pelletizing mechanism 200 further includes a drive device 04. The drive device 04 is located below the conveying device 01 and the positioning and cutting device 02. The drive device 04 switches the conveying device 01 between a clamped state and an unclamped state. The drive device 04 also drives the conveying device 01 to translate forward and backward. The drive device 04 switches the positioning and cutting device 02 between an unclamped state, a clamped state, and a cutting state. For example, when the conveying device 01 is in the clamped state, it clamps the metal wire. When the drive device 04 drives the conveying device 01 forward, it conveys the metal wire forward. When the conveying device 01 is in the unclamped state, the drive device 04 drives the conveying device 01 backward, resets it, and begins the next feeding phase. When the positioning and cutting device 02 is in the unclamped state, the metal wire is fed into the positioning and cutting device 02. When the positioning and cutting device 02 is in the clamped state, it clamps the metal wire. When the positioning and cutting device 02 is in the cutting state, the metal wire located therein is cut off.

[0067] As shown in Figures 1 to 4 and 7 to 19 , the positioning and cutting device 02 includes a cutting channel 022 for the metal wire to pass through. Cutting channel 022 is expandable and retractable. Cutting channel 022 expands when the positioning and cutting device 02 is in the open position and retracts when the positioning and cutting device 02 is in the clamped and cutting positions. It should be noted that the size of cutting channel 022 remains substantially the same when the positioning and cutting device 02 is in the clamped and cutting positions.

[0068] As shown in Figures 1 to 4 and Figures 7 to 19, the positioning and cutting device 02 includes a driven member 023, a lower clamping member 024, an upper cutter 025, and a lower cutter 026. The lower clamping member 024 is mounted on the driven member 023 and is located directly below the upper cutter 025. A cutting channel 022 is defined between the upper cutter 025 and the lower clamping member 024. The lower cutter 026 is mounted on the driven member 023. The lower cutter 026 is located to the right of the lower clamping member 024, with the upper cutter 025 and the lower cutter 026 being staggered in front and behind. A second channel 021 is located on top of the upper cutter 025. The driving device 04 drives the driven member 023 upward, thereby driving the lower clamping member 024 closer to the upper cutter 025, causing the cutting channel 022 to contract. As the driving device 04 continues to drive the driven member 023 upward, it drives the lower cutter 026 to cut the metal wire that has passed through the cutting channel 022. Before cutting, the lower clamp 024 and the upper cutter 025 approach each other, and the cutting channel 022 contracts, clamping the metal wire and positioning it. Then, the lower cutter 026 continues to move upward, cutting the metal wire that extends out of the cutting channel 022 to produce metal pellets.

[0069] Preferably, lower clamping member 024 has a sliding cavity 0241, driven member 023 has a connecting structure 0231 extending into sliding cavity 0241, a slide post 0242 is mounted in sliding cavity 0241, connecting structure 0231 is slidably mounted on slide post 0242, slide post 0242 is fitted with a biasing spring 0243, biasing spring 0243 is disposed between lower clamping member 024 and connecting structure 0231, biasing spring 0243 constantly tends to drive connecting structure 0231 downward. Slide post 0242 serves to guide and limit the position of driven member 023. The advance spring 0243 acts as a buffer to prevent the driven member 023 from continuing to advance upward. Specifically, the driving device 04 drives the driven member 023 upward, driving the lower clamping member 024 upward as well. The lower clamping member 024 and the upper cutter 025 clamp the metal wire. At this point, the advance spring 0243 is compressed, but not significantly, and the lower cutter 026 is positioned below the metal wire. The driving device 04 drives the driven member 023 further upward, compressing the advance spring 0243 and driving the lower cutter 026 upward, thereby cutting the metal wire into metal particles.

[0070] As shown in Figures 9 to 13, the rear end of the upper cutter 025 defines a retaining slot 0251. A retaining plate 027 is removably mounted to retaining slot 0251. Retaining plate 027 defines a retaining hole 0271 extending from front to back for the metal wire to pass through. The metal wire entering the cutting channel 022 passes through retaining hole 0271, where retaining plate 027 provides a positional limit for the wire. Since metal wire diameters vary, the corresponding retaining holes 0271 also vary in size. By replacing retaining plates 027, the size of the retaining holes 0271 can be adjusted to accommodate metal wires of corresponding sizes.

[0071] As shown in Figures 14 to 19, the conveying device 01 includes an upper clamp 012, a support seat 013, and a sliding member 014. The upper clamp 012 is mounted on the support seat 013 so that it can slide up and down. A spring member 015 is installed between the upper clamp 012 and the support seat 013. A clamping channel 016 that can expand and contract is defined between the upper clamp 012 and the support seat 013. The spring member 015 has a constant tendency to drive the upper clamp 012 and the support seat 013 closer together, causing the clamping channel 016 to contract. The upper clamp 012 is mounted on the sliding member 014 so that it can slide back and forth. The driving device 04 drives the sliding member 014 upward, thereby driving the upper clamp 012 upward, thereby expanding the clamping channel 016. The driving device 04 is connected to the support seat 013 and drives the support seat 013 and the upper clamp 012 to move forward and backward synchronously. When the conveyor 01 is in a relatively rearward position, the upper clamp 012 and the support base 013 approach each other, and the clamping channel 016 contracts to clamp the metal wire. The drive device 04 simultaneously drives the conveyor 01 to translate forward. When the conveyor 01 moves to a relatively close position, the drive device 04 drives the upper clamp 012 upward, and the upper clamp 012 and the support base 013 loosen their grip on the metal wire. Next, the drive device 04 drives the conveyor 01 to translate backward back to its initial position, preparing for the next feeding.

[0072] As shown in Figures 2 to 19, the drive device 04 includes a drive motor 041 and a camshaft 042. Camshaft 042 is mounted on the output end of drive motor 041, and drive motor 041 drives camshaft 042 to rotate. Camshaft 042 is axially arranged with a first cam 043, a second cam 044, and a third cam 045. The support seat 013 abuts against the contour of the first cam 043 via a first roller 046, the upper clamping member 012 abuts against the contour of the second cam 044 via a second roller 047, and the driven member 023 abuts against the contour of the third cam 045 via a third roller 048. The drive motor 041 drives the camshaft 042 to rotate, thereby pushing the conveying device 01 forward and backward through the first cam 043. The drive motor 041 drives the camshaft 042 to rotate, thereby pushing the upper clamp 012 up and down through the second cam 044. The drive motor 041 drives the camshaft 042 to rotate, thereby pushing the driven member 023 up and down through the third cam 045. The above-mentioned method of driving the conveying device 01, the upper clamp 012, and the driven member 023 to move through the cam is the same as the prior art and is well known to those skilled in the art, so it will not be repeated here. Preferably, a return spring 0232 is installed between the driven member 023 and the frame 300. The return spring 0232 always has a tendency to drive the driven member 023 downward, and the return spring 0232 drives the driven member 023 to return downward.

[0073] The following briefly describes the manufacturing process of the metal wire flattening, forming, conveying, and pelletizing apparatus 1000 of the present application. First, the flattening and discharging mechanism is described: The drive motor 041 rotates the camshaft 042, which, via the first cam 043, pushes the conveyor 01 forward, moving the clamped metal wire forward. At this point, the metal wire is tensioned, and the input guide wheel 50 is pressed, causing the swinging member 20 to rotate. The first portion 21 rotates slightly downward, and the second portion 22 rotates slightly upward. The bump structure 23 leaves the detection opening 31, triggering the photoelectric sensor 30 and causing the flattening wheel assembly 10 to operate. The driver 11 drives the worm 14 to rotate, and the worm 14 drives the worm wheel 15 to rotate. The upper gear 17 and the lower gear 16 are engaged and transmitted, so that the upper pressing wheel 12 and the lower pressing wheel 13 rotate relative to each other. The upper pressing wheel 12 and the lower pressing wheel 13 flatten the metal wire and output it. The output metal wire first passes over the input guide wheel 50 upward and then passes over the guide rod 70 downward, and then passes over the output guide wheel 40 to replenish the metal wire forward.

[0074] Next, the processing of the conveying and pelletizing mechanism 200 will be described. The drive device 04 forces the conveying device 01 into a clamping state, thereby clamping the metal wire, and drives the conveying device 01 to move horizontally from back to front. The conveying device 01 feeds the clamped metal wire into the positioning and cutting device 02. During this process, the drive device 04 drives the positioning and cutting device 02 to switch from an open state to a clamped state, thereby clamping the fed metal wire. As the material picker 400 moves downward, passing through the first channel 011 and the second channel 021, communication between the receiver 031 and the transmitter 032 is interrupted, triggering the photoelectric sensor 03, which in turn drives the drive device 04 to switch the positioning and cutting device 02 into a cutting state. The lower cutter 026 moves upward, cutting the metal strip extending from the cutting channel 022, producing metal pellets. The material picker 400 then removes the absorbed metal pellets. During this process, the drive unit 04 switches the conveyor unit 01 to an open state and drives the conveyor unit 01 to move forward. Shortly thereafter, the drive unit 04 switches the positioning and cutting unit 02 to an open state. The drive unit 04 then switches the conveyor unit 01 to a clamped state, thereby clamping the metal wire. The drive unit 04 then drives the conveyor unit 01 to move forward, feeding the clamped metal wire into the positioning and cutting unit 02. Repeating this process continuously produces metal pellets. The above process is summarized as steps 1-2 in Figure 1.

[0075] As shown in FIG2 , the direction indicated by arrow X is from front to back, the direction indicated by arrow Y is from left to right, and the direction indicated by arrow Z is from bottom to top.

[0076] The above disclosure is only a preferred example of the present application and cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are all within the scope covered by the present application.
