A winding back-up device and coil production equipment

Abstract

The present invention discloses a post-winding push-up device and coil production equipment. The post-winding push-up device presses the coil bobbin against the winding end of the winding machine's main shaft assembly, addressing issues such as inaccurate coil bobbin positioning and easy loosening, which can affect coil winding accuracy. The post-winding push-up device's first sleeve, spring, and other components form an elastic adjustment structure that accommodates coil bobbins of varying sizes. This also eliminates the problem of poor coil winding consistency caused by positional deviations between coil bobbins inserted into the winding end at each winding station during multi-station winding.

Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, in particular to a winding back-up device and coil production equipment. Background Art

[0002] Coils are commonly used electronic components in electronic products, generally including a coil bobbin, pins mounted on the coil bobbin, and copper wire wound on the coil bobbin.

[0003] The production of coils generally includes processes such as winding, tinning, and bending. Each process can be carried out separately or integrated to form an automated production line. However, existing coil production equipment has some shortcomings. For example, when winding copper wire, the coil skeleton is generally inserted into the winding end of the winding machine, and the coil is removed after the winding is completed. Existing fully automatic winding machines generally use the friction principle. By setting an elastic element on the winding end, its size is slightly larger than the inner hole of the coil skeleton. After the coil skeleton is inserted into the winding end, the friction between the inner hole wall of the coil skeleton and the outer wall of the elastic element remains fixed. This fixing method has the problem of inaccurate positioning. After a period of use, the elastic element wears and the friction force decreases, causing the coil skeleton to loosen and slide relative to the winding end, thereby affecting the quality of the finished coil.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 As shown, the coil production equipment of this embodiment includes: a loading machine 100, a winding machine 200, a tinning and bending machine 300 and a tray loading machine 400.

[0036] Please refer to Figure 2 In this embodiment, the loader 100 includes: a first tray stacking device 101, a first tray handling device 102, a coil conveying device 103, and a first variable-pitch feeding device 104. The first tray stacking device 101 is used to stack empty trays and fully loaded trays. The first tray handling device 102 is located between the first tray stacking device 101 and the first variable-pitch feeding device 104. The first variable-pitch feeding device 104 is located between the first tray handling device 102 and the coil conveying device 103. The coil conveying device 103 connects the winding machine 200 and the tinning and bending machine 300 in series. The first tray handling device 102 removes the stacked, fully loaded trays from the first tray stacking device 101 one by one and conveys them to the first variable-pitch feeding device 104. The first variable-pitch feeding device 104 then picks up multiple coil bobbins from the first tray handling device 102 at once, adjusts the spacing between the coil bobbins, and places the coil bobbins onto the coil conveying device 103 for conveyance. After all the coil bobbins in the tray have been conveyed, the first tray handling device 102 conveys the empty tray to the first tray stacking device 101 for stacking, and then conveys another fully loaded tray.

[0038] The spindle device 202 is the main body of the winding machine 200 , and the coil conveying device 103 conveys the coil bobbin to the winding machine 200 and installs the coil bobbin on the winding end of the spindle device 202 .

[0039] Please refer to Figure 4 The wire guide device 206 includes: a plurality of wire guide assemblies 207, a first translation mechanism 208, a second translation mechanism 209, and a first lifting mechanism 210. The wire cutting device 203 includes: a second lifting mechanism 205 and a plurality of pneumatic scissors 204. The second translation mechanism 209 is fixed to the moving part of the first translation mechanism 208, the first lifting mechanism 210 is fixed to the moving part of the second translation mechanism 209, the wire guide assemblies 207 and the second lifting mechanism 205 are fixed to the moving part of the first lifting mechanism 210, and the pneumatic scissors 204 are fixed to the moving part of the second lifting mechanism 205.

[0040] Please refer to Figure 5 The wire clamping device 211 includes: a plurality of wire clamps 212, a third translation mechanism 213, a third lifting mechanism 214, and a first flipping mechanism 215. The third lifting mechanism 214 is fixed to the moving part of the third translation mechanism 213, the first flipping mechanism 215 is fixed to the moving part of the third lifting mechanism 214, and the wire clamps 212 are fixed to the flipping rod of the first flipping mechanism 215.

[0041] Please refer to Figure 6 The winding rear top device 216 includes: a main board 217, a first driving mechanism 234 and a plurality of rear top rotating shaft components 219. The main board 217 is provided with a plurality of horizontal jacks 218 that pass through the main board 217. Figure 7 and Figure 8The rear top shaft assembly 219 includes a first sleeve 220, a stop plate 224, a spring 225, a rotating shaft 226, a first bearing 228, a second bearing 229, a positioning member 230, and a spring plate 231. A first outer shoulder 221 is formed on the outer wall of the first end of the first sleeve 220. The second end of the first sleeve 220 passes through the spring 225 and the horizontal insertion hole 218 in sequence and then connects to the stop plate 224. This allows the spring 225 to contact the first outer shoulder 221 and the main plate 217, and the stop plate 224 to contact the main plate 217. A first bearing 228 and a second bearing 229 are fixed axially spaced apart within the first sleeve 220. A second outer shoulder 227 is formed on the outer wall of the first end of the rotating shaft 226. The second end of the rotating shaft 226 passes through the first and second bearings 228, 229, and then connects to the positioning member 230, so that the positioning member 230 abuts the inner race of the second bearing 229, and the second outer shoulder 227 abuts the inner race of the first bearing 228. A spring plate 231 is fixed to the first end of the rotating shaft 226. After the coil bobbin A is installed on the winding end of the spindle assembly 202, the first drive mechanism 234 drives the rear push shaft assembly 219 to axially press the coil bobbin A toward the coil bobbin. At this time, the second end of the first sleeve 220 gradually extends out of the horizontal insertion hole 218, and the spring 225 assembly is gradually compressed, converting the elastic potential energy of the spring 225 into pressure applied to the coil bobbin A, forcing the coil bobbin A to be pressed tightly between the spring plate 231 and the winding end. The post-winding push device 216 solves the problem of inaccurate positioning of the coil frame A affecting the coil winding accuracy. The pressure on the coil frame A is converted from the elastic potential energy of the spring. While pressing the coil frame A tightly, it avoids excessive compression and damage to the coil.

[0042] In order to prevent the rear top rotating shaft assembly 219 from rotating circumferentially in the horizontal socket 218 and affecting the winding accuracy of the coil, an axially extending sliding groove 234 is opened on the outer wall of the second end of the first sleeve 220, and a sliding member 232 is fixedly inserted into the sliding groove 234 on the main board 217 to limit the circumferential rotation of the rear top rotating shaft assembly 219.

[0043] In order to facilitate the assembly, disassembly and maintenance of the rear top device, a first inner shoulder 222 can be set on the inner wall of the first end of the first sleeve 220, and a second inner shoulder 223 can be set on the inner wall of the second end of the first sleeve 220, so that the first bearing 228 is fixed by abutting between the second outer shoulder 227 and the first inner shoulder 222, and the second bearing 229 is fixed by abutting between the second inner shoulder 223 and the positioning member 230, and a second sleeve 233 is sleeved on the rotating shaft 226 to abut between the first bearing 228 and the second bearing 229.
