Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a tin material feeding device. Background Technology

[0002] Solder balls are spherical objects made primarily of tin. They have excellent electrical conductivity and ductility and are widely used in chip packaging, PCB board soldering, and other applications. They are key components in electronic manufacturing for achieving electrical connections and mechanical fixation.

[0003] Because tin is a relatively soft metal, when making solder balls, the tin material is usually stretched into strips and wound orderly on a feed cylinder. The feed cylinder and the support are connected by a bearing. When the processing equipment applies a traction force to the tin material, causing the feed cylinder to rotate and feed, the friction generated by the rotation of the bearing is relatively small. In addition, the feed cylinder itself has a large inertia. If the traction force applied by the equipment is too large, the feed cylinder will rotate excessively due to inertia. This will cause the tin material between the feed cylinder and the processing equipment to lose its tautness, resulting in loosening. The loosening of the tin material will not only affect the stability and continuity of feeding, but may also cause problems such as tin material stacking and entanglement, seriously interfering with the normal process flow of solder ball making, reducing production efficiency and product quality.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, in one embodiment, a tin material feeding device includes: a feeding cylinder 1, a clamping assembly 2, and a damping assembly 3.

[0030] The feed cylinder 1 is rotatably connected to the rotating shaft 7, ensuring that the feed cylinder 1 can unwind the strip material in a stable and continuous manner under the traction of the processing equipment, and continuously transport the tin material to the processing station.

[0031] Furthermore, the clamping assembly 2 includes a first clamping plate 21 and a second clamping plate 22, which are detachably installed at the end of the feed cylinder 1 for enclosing and clamping the clamping cylinder 23. When it is necessary to replace the feed cylinder 1 of different specifications or to maintain the clamping assembly 2, the operator can easily disassemble and reinstall the clamping plates, effectively improving versatility and ease of maintenance.

[0032] Specifically, the clamping cylinder 23 is rotatably connected to the feed cylinder 1, and a rotary bearing 4 is provided on the outside of the clamping cylinder 23; correspondingly, the rotary bearing 4 is mounted on the bearing bracket 5, and the bearing bracket 5 is mounted on the support bracket 6.

[0033] It should be noted in detail that one end of the first clamping plate 21 and the second clamping plate 22 is rotatably connected to the end of the rotating shaft 7, which facilitates the installation and replacement of the first clamping plate 21 and the second clamping plate 22; the other end of the first clamping plate 21 and the second clamping plate 22 is detachably equipped with a tightening stud 8, which can be adjusted according to the actual working conditions and the needs of conveying the strip, so as to precisely control the clamping force of the first clamping plate 21 and the second clamping plate 22 on the clamping cylinder 23 and the rotating shaft 7.

[0034] Furthermore, the damping assembly 3 includes a fixed plate 31 and a stop bar 32, which are detachably mounted on one side of the clamping assembly 2 to provide resistance.

[0035] It should be explained in detail that a fixing plate 31 is installed at one end of the second clamping plate 22 by means of quick connection such as bolts or buckles, which not only ensures the installation of the fixing plate 31 firmly, but also facilitates disassembly and replacement; while a stop bar 32 is inserted at one end of the fixing plate 31, and the stop bar 32 abuts against the upper end face of the support bracket 6, so that resistance can be applied to the feed cylinder 1 during unwinding, thereby keeping the strip taut and avoiding problems such as strip stacking or tangling.

[0036] Working principle: A clamping assembly 2 and a damping assembly 3 are installed between the feed cylinder 1 and the bearing bracket 5. The rotating shaft 7 is fixed by tightening the studs 8 and a set of clamping plates. The resistance is provided by the fixing plate 31 and the stop bar 32 to reduce the inertia of the feed cylinder 1 when it rotates, thereby preventing the feed cylinder 1 from rotating too much. This allows the strip to remain taut and be continuously conveyed to the processing station, effectively improving the stability and continuity of the feeding.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
