Description

Technical Field

[0001] The utility model relates to the technical field of tin wire pelletizing mechanisms, in particular to a tin wire pelletizing mechanism and a device. Background Art

[0002] With the continuous development of science and technology and economy, the soldering of electronic equipment has also become diversified, such as wave soldering, reflow soldering, BGA soldering, etc., which require special treatment of solder or use of solder in a specific state. For example, BGA soldering uses tin beads or paste to place tin, so that it can be soldered normally.

[0003] Currently, in some SMD soldering operations, solder is replenished directly using tin wire, but the amount of tin supplied cannot be controlled, resulting in excessive or insufficient soldering. To facilitate soldering and ensure the proper amount of tin supply, granular solder is generally made from finished solder, such as by hand-cutting or hot-melting. Although hot-melting can ensure uniformity of granularity, the finished solder generally contains fluxing materials that may lose their effectiveness under high temperatures. Manually cut granularity cannot guarantee uniformity, thus preventing insufficient or excessive solder replenishment during soldering. Therefore, the present application proposes a tin wire granulating mechanism to at least partially address the problems that may exist in the prior art. Utility Model Content

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0037] Example

[0038] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features thereof may be combined with each other.

[0039] Please refer to Figures 1 to 7 As shown, the embodiment of the present invention provides a tin wire pelletizing mechanism, which includes: a driving assembly, the driving assembly includes a motor 101 and a fixed block 107, the output end of the motor 101 is sequentially connected to a first spiral wheel 108 and a first gear 103, and then rotatably connected to the fixed block 107;

[0040] The conveying assembly includes a first movable column 109 and a movable platform 110. The first movable column 109 is disposed between the first spiral wheel 108 and the first gear 103 and abuts against the side wall of the first spiral wheel 108. One end of the movable platform 110 is fixedly connected to the first movable column 109, and the other end of the movable platform 110 is connected to the fixed block 107 via a transversely arranged first spring 111. A tin wire 230 conveying groove is provided on the top of the movable platform 110.

[0041] The cutting blade assembly is vertically elastically installed on the cutting platform 113, which is located at the rear end of the conveying assembly. A cutting groove 114 is provided on the top of the cutting platform 113;

[0042] A transmission shaft 115 is provided below the conveying assembly and the cutter assembly. A second gear 104 is provided at one end of the transmission shaft 115 close to the motor 101, and the second gear 104 is engaged with the first gear 103. A first boss 116 is provided on the transmission shaft 115, and the first boss 116 is opposite to the bottom of the cutter assembly and can abut against the cutter assembly during the rotation of the transmission shaft 115.

[0043] In the embodiment of the present application, a motor 101 drives the first spiral wheel 108 and the first gear 103 to rotate. The first movable column 109 abuts against the first spiral wheel 108, causing the first movable column 109 to move horizontally during the rotation of the first spiral wheel 108. This, in conjunction with the first spring 111, drives the movable platform 110 to move horizontally back and forth, conveying the tin wire 230 through the tin wire 230 conveyor trough. The first gear 103 engages with the second gear 104 at the end of the transmission shaft 115, driving the transmission shaft 115 to rotate, thereby rotating the first boss 116 on the transmission shaft 115. The first boss 116 propels the cutter assembly to reciprocate up and down, cutting the tin wire 230 conveyed to the cutter platform. By combining various mechanical components and spring designs, the present invention effectively addresses issues such as precision, efficiency, and stability in the tin wire 230 cutting process, resulting in high practicality and reliability.

[0044] Next, a tin wire dicing mechanism 100 in this exemplary embodiment will be further described.

[0045] In the embodiment of the present application, the drive assembly includes a motor 101 and a fixed block 107. The output end of the motor 101 is connected to a first spiral wheel 108 and a first gear 103 in sequence, and then rotatably connected to the fixed block 107. The fixed block 107 is U-shaped, and the first spiral wheel 108 and the first gear 103 are both located in the U-shaped cavity of the fixed block 107. The fixed block 107 also supports the output shaft of the motor 101. The first spiral wheel 108 and the first gear 103 are driven to rotate by the motor 101.

[0046] In the embodiment of the present application, the conveying assembly includes a first moving column 109 and a moving platform 110 . The first moving column 109 is disposed between the first spiral wheel 108 and the first gear 103 and abuts against the side wall of the first spiral wheel 108 .

[0047] It should be noted that the spiral wheel has an undulating surface, and the side surface of the first movable column 109 abuts against the undulating surface, so that the undulating surface can push the first movable column 109 to move horizontally when the spiral wheel rotates.

[0048] One end of the mobile platform 110 is fixedly connected to the first mobile column 109, and the other end of the mobile platform 110 is connected to the fixed block 107 via a transversely arranged first spring 111. Two first springs 111 can be provided, one on each side of the bottom of the mobile platform 110. A tin wire 230 conveying trough is provided on the top of the mobile platform 110 for conveying the tin wire 230. The movement of the first mobile column 109 drives the mobile platform 110 to move horizontally synchronously. Under the elastic recovery effect of the first spring 111 and the continuous rotation of the first spiral wheel 108, the mobile platform 110 can be moved horizontally back and forth, so that it is always in a state of conveying the tin wire 230, thereby continuously conveying the tin wire 230 to the cutter assembly for cutting, further improving efficiency.

[0049] In the embodiment of the present application, the above-mentioned cutting blade assembly is elastically installed vertically on the cutting platform 113, that is, the cutting blade assembly can reciprocate up and down in the vertical direction. The above-mentioned cutting platform 113 is arranged at the rear end of the movable platform 110. The cutting platform 113 has a U-shaped structure with an opening facing downward, and its opposite sides are used to connect and fix with the device. The cutting platform 113 is provided with a cutting groove 114 at the top, and the cutting groove 114 is connected to the tin wire 230 conveying groove. The tin wire 230 is transported to the cutting platform 113 by the conveying assembly, and the tin wire 230 is cut by the up and down movement of the cutting blade assembly, and cut into tin particles.

[0050] In the embodiment of the present application, the transmission shaft 115 is disposed below the conveyor assembly and the cutter assembly. A second gear 104 is disposed on the end of the transmission shaft 115 near the motor 101. The second gear 104 meshes with the first gear 103. The first gear 103 drives the second gear 104 to rotate, thereby driving the transmission shaft 115 to rotate. A first boss 116 is disposed on the transmission shaft 115. The first boss 116 is opposed to the bottom of the cutter assembly and is capable of abutting the cutter assembly as the transmission shaft 115 rotates. In other words, the rotation of the transmission shaft 115 drives the first boss 116 to rotate. When the first boss 116 rotates to abut the cutter assembly, it pushes the cutter assembly upward. When the first boss 116 rotates to separate from the cutter assembly, the cutter assembly moves downward due to its elastic recovery. This reciprocating up and down motion cuts the fed tin wire 230.

[0051] By using the design of the cutting boss, the tin wire 230 can be accurately cut into tin particles; through the design of the driving component and the first movable column 109 and the movable platform 110, the tin wire 230 can be continuously transported and cut, thereby improving production efficiency. In addition, the structure is relatively simple, and there will be no reverse or stagnation phenomena, which can ensure the stability and reliability of the transport and cutting process.

[0052] As an example, the above-mentioned cutting knife assembly includes a cutting block 120, a tin stopper 121 and a lever 122. The cutting block 120 is arranged inside the cutting platform 113 and passes through the top of the cutting platform 113. The bottom end of the cutting block 120 is opposite to the first boss 116. A feed trough 123 is provided at the top of the cutting block 120. The feed trough 123 is connected to the cutting groove 114. One side of the cutting block 120 is connected to the protective shell 200 through a vertically arranged second spring 124; that is, under the push of the first boss 116 and the recovery action of the second spring 124, the cutting table moves back and forth up and down, cutting the tin wire 230 conveyed into the feed trough 123 into tin particles.

[0053] The above-mentioned tin-stopping member 121 includes a moving part and an L-shaped tin-stopping part. One end of the moving part is horizontally slidably connected to the side wall of the cutting block 120, and the other end of the moving part is connected to the top limit of the lever 122; the vertical axis of the L-shaped tin-stopping part is integrally connected to the top of the moving part and has a moving gap with the cutting block 120, and the horizontal axis of the L-shaped tin-stopping part is located above the top surface of the cutting block 120; that is, the moving part can move horizontally on the side wall of the cutting block 120, the vertical axis of the L-shaped tin-stopping part can move synchronously driven by the moving part, and the horizontal axis can block and limit the tin wire 230 sent over.

[0054] The lever 122 is hingedly connected to the side wall of the cutting block 120 at its midpoint. The side wall of the lever 122 is connected to the cutting block 120 via a third spring 125. The bottom end of the lever 122 is connected to a second movable post 126, which abuts a second spiral wheel 127 fixed to the transmission shaft 115. The concave surface of the second spiral wheel 127 faces the first boss 116. In other words, the second spiral wheel 127 rotates under the drive shaft 115. The rotation of the second spiral wheel 127 pushes the second movable post 126 to move horizontally, thereby driving one end of the lever 122 to move horizontally. Under the elastic restoring action of the third spring 125, the lever 122 achieves horizontal reciprocating movement. The other end of the lever 122 then drives the tin stop 121 to move horizontally and reciprocatingly. By setting the concave surface of the undulating surface of the second spiral wheel 127 to be opposite to the first boss 116, when the first boss 116 rotates to abut against the cutting block 120 and pushes the cutting block 120 upward, the second movable column 126 abuts against the concave surface of the second spiral wheel 127, the second movable column 126 retracts, and the lever 122 drives the tin stop 121 to move outward to avoid affecting the cutting block 120; when the first boss 116 rotates to separate from the cutting block 120 and the cutting block 120 moves downward, the second movable column 126 abuts against the convex surface of the second spiral wheel 127, the second movable column 126 moves outward, and the lever 122 drives the tin stop 121 to move inward, thereby limiting and blocking the tin wire 230.

[0055] As an example, a laser sensor 129 is provided on the top of the cutting platform 113. Laser slots are provided on opposite sides of the feed trough 123, with the laser sensors 129 facing the laser slots. The laser sensors 129 are used to detect the presence of the tin wire 230. The sensors are detected when the tin wire 230 is fed into the feed trough 123.

[0056] In an embodiment of the present application, a flattening and forming assembly is also included, which is located between the cutting assembly and the conveying assembly. The flattening and forming assembly includes an extrusion block 117 and a pressure platform 118. The extrusion block 117 is elastically connected to the cutting platform 113 through a fourth spring 128, and the top of the extrusion block 117 is passed through the top of the cutting platform 113 and is flush with the cutting groove 114; the pressure platform 118 is fixed to the top of the cutting platform 113 and covers the extrusion block 117 and the cutting groove 114; a second boss 119 corresponding to the bottom of the extrusion block 117 is also provided on the transmission shaft 115, and the second boss 119 can abut against the extrusion block 117 during the rotation of the transmission shaft 115. The second boss 119 is driven to rotate by the transmission shaft 115. When the second boss 119 rotates to abut the bottom of the extrusion block 117, it pushes the extrusion block 117 upward. The top of the extrusion block 117 cooperates with the pressure platform 118 to squeeze the conveyed tin wire 230 into a flat shape, which facilitates subsequent cutting and prevents displacement during conveying after cutting. When the second boss 119 rotates to separate from the extrusion block 117, the extrusion block 117 moves downward and returns to its original position due to its elastic recovery effect.

[0057] Before the tin wire 230 is cut into tin particles by the flattening molding assembly, it is first flattened to reduce its thickness, making the tin wire 230 easier to cut. In addition, the cut tin particles will not roll to other places when poured onto a flat surface or transferred for storage, making them easier to store and use.

[0058] As an example, the transmission shaft 115 is connected to a third boss 130. The first boss 116, the second boss 119, and the third boss 130 are all arc-shaped bosses. The first boss 116 and the second boss 119 are arranged opposite each other, and the third boss 130 is arranged above and below the first boss 116 and the second boss 119. The design of the multiple bosses and their relative positional relationships enable the conveying, flattening, and cutting of the tin wire 230 to be performed stably and accurately. The bottom end of the cutting block 120 is rotatably connected to a first pulley 131 opposite the first boss 116, and the bottom end of the extrusion block 117 is rotatably connected to a second pulley 132 opposite the second boss 119.

[0059] The first pulley 131 causes the first boss 116 and the cutting block 120 to slide and rub against each other, thereby reducing friction. Furthermore, the second spring 124 allows the cutting block 120 to continuously and intermittently cut. Two or more cutting blocks 120 may be provided, depending on the cutting interval requirements.

[0060] The second pulley 132 is used to make the second boss 119 and the extrusion block 117 slide in friction, thereby reducing the friction force, and the extrusion block 117 is continuously and intermittently extruded under the elastic action; the flattening forming assembly can be flattened synchronously with the cutting knife assembly 3 during cutting.

[0061] As an example, a conveying block 133 is slidably inserted into the side of the movable platform 110 near the cutting block 120. The bottom end of the conveying block 133 is rotatably connected to a third pulley 134 opposite the third boss 130. The third pulley 134 causes sliding friction between the third boss 130 and the conveying block 133, thereby reducing friction. The top end of the conveying block 133 is inserted into a strip-shaped hole opened in the top of the movable platform 110 and is provided with a rough surface 135. The rough surface 135 is connected to the conveying groove of the tin wire 230. The provision of the rough surface 135 increases the friction between the conveying block 133 and the tin wire 230 during the movement of the movable platform 110, thereby ensuring stable conveyance of the tin wire 230. A positioning cover 136 is provided at the top of the movable platform 110 opposite the conveying block 133. The bottom of the positioning cover 136 is provided with a positioning groove opposite the rough surface 135. The positioning cover 136 can be used to position the tin wire 230 during transportation, and can also be used to more stably hold the tin wire 230 before cutting, thereby preventing the tin wire 230 from moving during cutting and ensuring cutting quality.

[0062] As an example, one side of the extrusion block 117 is slidably connected to the inner wall of the cutting platform 113 via a first slider 137, one side of the cutting block 120 is slidably connected to the inner wall of the cutting platform 113 via a second slider 138, and one side of the conveying block 133 is slidably connected to the inner wall of the moving platform 110 via a third slider 139. The vertical reciprocating movement or horizontal reciprocating movement of the above structure is connected by sliders and slide rails, which play a guiding role and improve stability during movement.

[0063] As an example, the motor 101 is connected to the first gear 103 via a coupling 102. A sensor plate 105 is provided between the coupling 102 and the first gear 103, rotating therewith, and a counter sensor 106 corresponding to the sensor plate 105. An inner protective shell 141 is provided outside the coupling 102 and connected to the motor 101. The sensor plate 105 and the corresponding counter sensor 106 can count the number of revolutions of the motor 101's shaft.

[0064] The present embodiment further provides a tin wire 230 pelletizing device, comprising the aforementioned tin wire pelletizing mechanism 100 and a protective housing 200. The tin wire pelletizing mechanism 100 is disposed within one end of the protective housing 200. The top of the mobile platform 110 is slidably connected to the protective housing 200 via a fourth slider 140. A tin feeding mechanism is disposed at the other end of the protective housing 200. The protective housing 200 protects the tin wire pelletizing mechanism 100, while the tin feeding mechanism feeds tin, preventing problems such as tangling of the tin wire 230 during transport.

[0065] As a preferred embodiment, the above-mentioned tin feeding mechanism includes a roller 210, on which a tin coil 220 with tin wire 230 wound is provided; a protective shell 200, in which a wire tube 260 is provided, a handle is provided on the outer side thereof, and a window 240 is provided at one end close to the tin feeding mechanism; the tin wire 230 can be released more smoothly through the above-mentioned roller 210 and tin coil 220, and the tin wire 230 can be protected during transportation through the above-mentioned wire tube 260 to prevent damage to the tin wire 230 during transportation, resulting in wire breakage, and whether the tin wire 230 has normally entered the wire tube can be observed through the above-mentioned window 240; the above-mentioned handle makes the above-mentioned tin wire cutting mechanism 100 a portable device, which is easy to carry, and the protective shell 200 is also provided with a handle groove, and the above-mentioned handle 250 can be folded inside the above-mentioned handle groove.

[0066] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be embraced therein.
