Abstract
Description
Technical Field
[0001] This application relates to the field of solder product manufacturing technology, and more specifically, to a solder column extrusion device. Background Technology
[0002] Solder pillars, as a commonly used semi-finished solder material in the welding process, require mechanical extrusion to achieve a shape transformation during the processing stage. This extrusion process is completed using specialized extrusion equipment, whose main structure consists of a frame with a through extrusion channel. The feed end of the extrusion channel is the extrusion port, and the discharge end is equipped with a forming mold. A hydraulic drive device is configured outside the extrusion port, which provides extrusion force through the reciprocating motion of a piston. In actual operation, the operator needs to transfer the cast high-temperature solder pillar to the extrusion port. The hydraulic drive device pushes the solder pillar axially along the extrusion channel. When passing through the orifice of the forming mold, the solder pillar undergoes plastic deformation under high pressure, and finally, a solder bar product with the required diameter is obtained from the mold outlet.
[0003] However, the existing process has operational bottlenecks: since the tin pillar has just completed the casting process, not only is there a risk of burns due to the residual heat, but also the high weight of a single pillar makes it difficult to position it manually during loading. In addition, each extrusion operation requires manual loading of the tin pillar, resulting in low work efficiency. Summary of the Invention
[0004] The purpose of this application is to provide a tin pillar extrusion device, which can solve the technical problems that, since the tin pillar has just completed the casting process, there is a risk of burns due to the residual heat, and the single pillar is heavy, making it difficult to position manually during material loading. In addition, each extrusion operation requires manual loading of the tin pillar, resulting in low work efficiency.
[0005] This application provides a solder pillar extrusion device, including a frame, on which an extrusion assembly and a feeding assembly are mounted. The feeding assembly includes a feeding pipe, a feeding box, and a feeding tray. The feeding pipe is connected to the top of the feeding box, and a single row of solder pillars is stacked inside the feeding pipe. A rotating roller is rotatably mounted inside the feeding box via a bearing. A sector-shaped disk is fixedly mounted on the rotating roller, and a receiving groove for accommodating solder pillars is provided between two adjacent sector-shaped disks. A driving assembly is mounted on the feeding box, which drives the rotating roller to rotate until the receiving groove corresponds to the bottom of the feeding pipe. An opening is provided on the side of the feeding box near the feeding tray. The extrusion assembly is used to extrude the solder pillars placed on the feeding tray.
[0006] The drive assembly includes a motor, which is fixedly mounted on the feeding box, and the output shaft of the motor is connected to the rotating roller.
[0007] The feeding tube has two symmetrically arranged limiting plates, and two screws are threaded through the feeding tube. The corresponding screws are rotatably connected to the corresponding limiting plates through bearings. A first guide rod is fixedly arranged on the limiting plate and slides through the feeding tube. Multiple solder pillars are stacked between the two limiting plates.
[0008] Thickened plates are detachably provided on both the rotating roller and the fan-shaped disk, and the thickened plates extend into the receiving groove.
[0009] The frame is fixedly provided with a guide plate, which is located between the feeding box and the feeding tray, and baffles are fixedly provided on the front and rear sides of the upper end of the guide plate.
[0010] The feeding assembly includes a hydraulic cylinder, a movable plate, a pusher block, and an extrusion die arranged sequentially from front to back. The piston rod end of the hydraulic cylinder is connected to the movable plate. The pusher block is fixedly mounted on the movable plate. The feeding support plate is located between the pusher block and the extrusion die. The pusher block can push the solder pillar into the extrusion die.
[0011] A cylinder is fixedly mounted on the frame, and the piston rod end of the cylinder is connected to the feeding tray.
[0012] A handle is fixedly provided at the end of the screw away from the limiting plate.

[0032] like Figure 1 and 2 As shown, this application embodiment provides a solder pillar extrusion device, including a frame 1, an extrusion assembly 2 and a feeding assembly 3 on the frame 1. The feeding assembly 3 includes a feeding pipe 31, a feeding box 32 and a feeding tray 33. The feeding pipe 31 is connected to the top of the feeding box 32, and a single row of solder pillars 4 are stacked inside the feeding pipe 31. A rotating roller 34 is rotatably arranged inside the feeding box 32 via a bearing. A sector disk 35 is fixedly arranged on the rotating roller 34. A receiving groove 36 for accommodating the solder pillars 4 is arranged between two adjacent sector disks 35. A driving assembly 5 is arranged on the feeding box 32. The driving assembly 5 is used to drive the rotating roller 34 to rotate until the receiving groove 36 corresponds to the bottom of the feeding pipe 31. An opening 37 is opened on the side of the feeding box 32 near the feeding tray 33. The extrusion assembly 2 is used to extrude the solder pillars 4 placed on the feeding tray 33.
[0033] In use, multiple solder pillars 4 are pre-loaded into the feeding tube 31 and stacked vertically in a single row. The solder pillar 4 at the bottom enters the feeding box 32 and falls into the receiving groove 36 on the rotating roller 34. Then, the rotating roller 34 is driven to rotate by the driving component 5, thereby driving the solder pillar 4 in the receiving groove 36 to rotate until the solder pillar 4 slides out from the opening 37 of the feeding box 32 and falls onto the feeding tray 33. Then, the extrusion component 2 can be used to extrude the solder pillar 4 placed on the feeding tray 33. When the rotating roller 34 drives the solder pillar 4 filled in the receiving groove 36 to rotate, the fan-shaped disk 35 will rotate to the bottom of the closed feeding tube 31 until the next feeding, when the fan-shaped disk 35 will rotate to the bottom of the open feeding tube 31 to fill the solder pillar 4.
[0034] This device can achieve batch loading and single automatic feeding, eliminating the need for manual feeding of the solder pillar 4 for each extrusion operation, reducing labor intensity, improving the continuity of material supply, and increasing production efficiency. Moreover, by setting the bottom of the feeding tube 31 to periodically open or close, only one solder pillar 4 is loaded each time, ensuring stable and orderly feeding and avoiding material jamming.
[0035] like Figure 1 and 2 As shown, in this embodiment, the drive component 5 includes a motor 51, which is fixedly mounted on the feeding box 32, and the output shaft of the motor 51 is connected to the rotating roller 34; in use, the motor 51 is turned on to drive the rotating roller 34 to rotate.
[0036] like Figure 1 and 2 As shown, in this embodiment, two limiting plates 38 are symmetrically arranged inside the feeding tube 31, and two screws 39 are threaded through the feeding tube 31. The corresponding screws 39 are rotatably connected to the corresponding limiting plates 38 through bearings. A first guide rod 310 is fixedly arranged on the limiting plate 38. The first guide rod 310 slides through the feeding tube 31, and multiple solder pillars 4 are stacked between the two limiting plates 38.
[0037] When it is necessary to feed solder pillars 4 of different sizes, the screw 39 is rotated to drive the limiting plate 38 to move, thereby adjusting the distance between the two limiting plates 38 to adapt to solder pillars 4 of different sizes, so as to ensure the vertical stacking of multiple solder pillars 4 and improve the applicability of the device; the first guide rod 310 and the feeding tube 31 work together to guide and limit the limiting plate 38.
[0038] like Figure 1 and 2As shown, in this embodiment, thickened plates 311 are detachably provided on both the rotating roller 34 and the fan-shaped disk 35, and the thickened plates 311 extend into the receiving groove 36. When it is necessary to feed solder pillars 4 of different sizes, a thickened plate 311 of appropriate thickness is selected and installed on the rotating roller 34 and the fan-shaped disk 35, thereby changing the depth and inner wall thickness of the receiving groove 36 to ensure that the receiving groove 36 can just match a single solder pillar 4, so that the feeding is stable and orderly, avoiding jamming of multiple materials and improving the applicability of the device.
[0039] like Figure 1 and 2 As shown, in this embodiment, a guide plate 11 is fixedly installed on the frame 1. The guide plate 11 is located between the feeding box 32 and the feeding tray 33, and baffles 12 are fixedly installed on the front and rear sides of the upper end of the guide plate 11.
[0040] When in use, the solder pillar 4 slides out from the opening 37 of the loading box 32, slides along the guide plate 11 and falls onto the loading tray 33; the guide plate 11 and the two baffles 12 form a guide channel to effectively guide the solder pillar 4, prevent the solder pillar 4 from falling and deviating, and improve the stability of use.
[0041] like Figure 1 and 2 As shown, in this embodiment, the feeding assembly 3 includes a hydraulic cylinder 21, a movable plate 22, a pusher block 23, and an extrusion mold 24 arranged sequentially from front to back. The piston rod end of the hydraulic cylinder 21 is connected to the movable plate 22. The pusher block 23 is fixedly arranged on the movable plate 22. The feeding support plate 33 is located between the pusher block 23 and the extrusion mold 24. The pusher block 23 can push the solder pillar 4 into the extrusion mold 24.
[0042] When in use, the hydraulic cylinder 21 is activated to move the movable plate 22. The pusher block 23 moves with the movable plate 22 to push the tin pillar 4 placed on the feeding plate 33 into the extrusion mold 24 and continuously apply pressure to perform the extrusion operation.
[0043] like Figure 1 and 2 As shown, in this embodiment, a cylinder 13 is fixedly installed on the frame 1, and the piston rod end of the cylinder 13 is connected to the feeding tray 33. When in use, the cylinder 13 is turned on to drive the feeding tray 33 to move up and down, so as to catch the solder pillar 4 sliding out from the feeding box 32 at a low position and align the solder pillar 4 with the extrusion die 24 at a high position. It also facilitates the avoidance of the feeding tray 33 during the extrusion operation.
[0044] like Figure 1 and 2 As shown, in this embodiment, a handle 312 is fixedly provided at the end of the screw 39 away from the limiting plate 38; the handle 312 makes it easier for the operator to apply force to rotate the screw 39, thus improving the ease of use.
[0045] like Figure 1 and 2 As shown, in this embodiment, the rotating roller 34 and the thickened plate 311, and the fan-shaped disk 35 and the thickened plate 311 are all connected by bolts; the thickened plate 311 can be quickly replaced by removing the bolts.
[0046] like Figure 1 and 2 As shown, in this embodiment, a second guide rod 14 is fixedly installed on the frame 1, and the movable plate 22 is slidably sleeved on the second guide rod 14; the cooperation between the movable plate 22 and the second guide rod 14 plays a guiding and limiting role for the movable plate 22, making the movement of the movable plate 22 more stable and smooth.
[0047] Working principle: When using the solder column extrusion device provided in this application, multiple solder columns 4 are pre-loaded into the feeding tube 31 and stacked vertically in a single row. The solder column 4 at the bottom enters the feeding box 32 and falls into the receiving groove 36 on the rotating roller 34. Then, the motor 51 is turned on to drive the rotating roller 34 to rotate, thereby driving the solder column 4 in the receiving groove 36 to rotate until the solder column 4 slides out from the opening 37 of the feeding box 32, slides along the guide plate 11 and falls onto the feeding tray 33. Then, the cylinder 13 is turned on to drive the extrusion device. The feeding tray 33 rises to the target height, and then the hydraulic cylinder 21 is activated to drive the movable plate 22 to move. The pusher block 23 moves with the movable plate 22 to push the solder pillar 4 placed on the feeding tray 33 into the extrusion die 24 and continuously apply pressure to perform the extrusion operation. When the rotating roller 34 drives the solder pillar 4 filled in the receiving groove 36 to rotate, the fan-shaped disk 35 will rotate to the bottom of the closed feeding tube 31 until the next feeding, when the fan-shaped disk 35 will rotate to the bottom of the open feeding tube 31 to fill the solder pillar 4.
[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
