Description

Technical Field

[0001] The present invention relates to the technical field of mask production, and particularly to an earline welding device. Background Art

[0002] In the production process of masks, one of the production steps is to weld the earlines to both sides of the main body of the mask. In the existing mask production lines, ultrasonic welding devices are usually used to weld the earlines to both sides of the main body of the mask. However, the production efficiency of the existing mask production lines is very low. For example, the existing earline welding device can only complete about 60 PCS of earline welding per minute. In recent years, with the sharp increase in the consumption of masks, the production efficiency of the existing earline welding devices has been difficult to meet the market demand. Summary of the Invention

[0004] An earline welding device according to one aspect of the present invention is used to weld the earlines of a mask to the main body of the mask, and includes: a workbench for holding the main body of the mask; a first mounting seat disposed above the workbench; an earline holding part having a first driving component and two earline holding components, the first driving component being mounted to the first mounting seat, the earline holding components being respectively connected to the first driving component and driven by the first driving component in the vertical direction, the earlines being held in the earline holding components and respectively located on both sides of the main body; a pressing part having a second driving component and a pressing head, the second driving component being mounted to the first mounting seat, the pressing head including a plurality of, the pressing head being connected to the second driving component and respectively located on both sides of the main body, and being driven by the second driving component in the vertical direction; a welding part disposed below the workbench, having a welding head, the welding head being opposite to the pressing head in the vertical direction; when the pressing head is driven downward by the second driving component, the pressing head respectively presses the earlines and the main body against the welding head, so that the earlines are welded to both sides of the main body.

[0005] The earline welding device according to one aspect of the present invention has at least the following beneficial effects: Since a first driving component for independently driving the earline holding components and a second driving component for independently driving the pressing head are provided, the operations of feeding the earlines to the main body of the mask and welding the earlines to the main body of the mask can be performed almost simultaneously. Therefore, the welding efficiency of the earlines of the mask can be greatly improved.

[0006] In some embodiments, the first driving component includes a second mounting seat, and the earline holding components are rotatably mounted to the second mounting seat.

[0007] In some embodiments, there are also two rotation driving parts, which are respectively connected to the ear wire holding assemblies and respectively drive the ear wire holding assemblies to rotate.

[0008] In some embodiments, each of the ear wire holding assemblies respectively includes: a holding seat, with the ear wire attached to the outer periphery of the holding seat; two clamping members, which are respectively installed on the holding seat and can be opened or closed relative to the holding seat. In the closed state, the ear wire is clamped and held on the holding seat, and in the open state, the ear wire is released.

[0009] In some embodiments, the pressing part further includes a closing driving member, which is installed on the second driving assembly. When being driven downward by the second driving assembly, the closing driving member presses the clamping member to close the clamping member relative to the holding seat.

[0011] In some embodiments, the wire removing part further has an opening driving member, which is connected to the third driving assembly and is driven by the third driving assembly in the up and down direction. When being driven downward by the third driving assembly, the opening driving member presses the clamping member to open the clamping member relative to the holding seat.

[0028] Figure 9 is a schematic diagram of the mask 100. Referring to Figure 9 , before describing the earline welding device 200 of the present invention, the structure of the mask 100 will be described first. Specifically, the mask 100 includes a main body portion 101 and earlines 102. The main body portion 101 is the part that covers a person's mouth and nose, and is formed by laminating two layers of non-woven fabric on the outside and a meltblown fabric layer between the two layers of non-woven fabric. The earlines 102 are ropes that are hung on a person's ears. The earlines 102 include two, and are respectively welded to both sides of the main body portion 101.

[0029] Figure 1 is a perspective view of the earline welding device 200 of the present invention in the top view direction, Figure 2 is a perspective view of the earline welding device 200 in the bottom view direction. Referring to Figure 1 , Figure 2 , the earline welding device 200 of the present invention is used to weld the earlines 102 of the mask 100 to the main body portion 101 of the mask 100, and includes: a workbench 201, a first mounting seat 202, an earline holding portion 203, a pressing portion 204, and a welding portion 205. Among them, the workbench 201 is used to hold the main body portion 101 of the mask 100. The first mounting seat 202 is arranged above the workbench 201. The earline holding portion 203 has a first driving component 206 and two earline holding components 207. The first driving component 206 is installed on the first mounting seat 202. The earline holding components 207 are respectively connected to the first driving component 206 and are driven by the first driving component 206 in the up and down direction. The earlines 102 are held in the earline holding components 207 and are respectively located on both sides of the main body portion 101. The pressing portion 204 has a second driving component 208 and a pressing head 209. The second driving component 208 is installed on the first mounting seat 202. The pressing head 209 includes a plurality of them. The pressing head 209 is connected to the second driving component 208 and is respectively located on both sides of the main body portion 101, and is driven by the second driving component 208 in the up and down direction. The welding portion 205 is arranged below the workbench 201. The welding portion 205 has a welding head 210. The welding head 210 and the pressing head 209 are opposite to each other in the up and down direction. When the pressing head 209 is driven downward by the second driving component 208, the pressing head 209 presses and abuts the earlines 102 and the main body portion 101 against the welding head 210 respectively, so that the earlines 102 are welded to both sides of the main body portion 101.

[0030] In this embodiment, since the first driving component 206 that independently drives the earline holding component 207 and the second driving component 208 that independently drives the pressing head 209 are provided, the operations of feeding the earline 102 toward the main body portion 101 of the mask 100 and welding the earline 102 to the main body portion 101 of the mask 100 can be performed almost simultaneously. Therefore, the welding efficiency of the earline 102 of the mask 100 can be greatly improved.

[0031] Specifically, the workbench 201 can be disposed on the base 211 for loading the main body portion 101. The main body portion 101 is sent to the workbench 201 through, for example, a conveyor belt 212 or the like. The workbench 201 is located below the conveyor belt 212.

[0032] Specifically, the first mounting seat 202 can be erected above the workbench 201 through, for example, a support column 213 or the like.

[0033] Specifically, the welding portion 205 can use a welding device well-known to those skilled in the art, such as an ultrasonic welding device, and the welding head 210 is an ultrasonic welding head.

[0034] Figure 3 is a perspective view of the earline holding portion 203 and the pressing portion 204. Refer to Figure 3 and continue to refer to Figure 1 , in some embodiments, in order to optimize the installation positions of the first driving component 206 and the second driving component 208 to easily layout the two earline holding components 207 and the pressing head 209, there are two second driving components 208, which are respectively located on both sides of the first driving component 206. The pressing head 209 includes four, two of which are respectively connected to one of the second driving components 208, and the other two pressing heads 209 are respectively connected to the other second driving component 208. Specifically, the first driving component 206 is located in the middle of the first mounting seat 202 and drives the two earline holding components 207 holding the earline 102 to move downward and abut against the main body portion 101. The second driving components 208 are located on both sides of the first mounting seat 202, and each drives the two pressing heads 209 to press down to respectively press the two ends of the earline 102 onto the main body portion 101. Thus, the positions of the earline holding components 207 and the pressing head 209 can be reasonably laid out according to the structure of the mask 100, making the mechanism more compact.

[0035] The first driving component 206 includes a first actuating element 214, a first linear guide 215 for guiding the first actuating element 214, a second mounting seat 216, and a first floating joint 217. Among them, the first actuating element 214 selects a linear actuating element such as an electric cylinder or a pneumatic cylinder. From the perspective of further improving the efficiency of the ear wire welding device 200 and reducing the noise of the device, an electric cylinder is preferred. The first linear guide 215 selects a linear guide shaft or a linear slide rail, and from the perspective of installation convenience, a linear guide shaft is preferred. In addition, in order to make the structure of the first driving component 206 more compact, the first linear guide 215 is mounted on the indenter mounting plate 218 (described below) of the second driving component 208. The second mounting seat 216 is floatingly connected to the first actuating element 214 through the first floating joint 217. In addition, a first linear bearing 219 is mounted on the second mounting seat 216, and the first linear bearing 219 slides along the first linear guide 215. The ear wire holding component 207 is mounted on the second mounting seat 216. Thus, while the first actuating element 214 drives the second mounting seat 216 to move up and down, the two ear wire holding components 207 move together with the second mounting seat 216.

[0036] The second driving component 208 includes a second actuating element 220, a second linear guide 221 for guiding the second actuating element 220, an indenter mounting plate 218, and a second floating joint 222. Among them, the second actuating element 220 selects a linear actuating element such as an electric cylinder or a pneumatic cylinder. From the perspective of further improving the efficiency of the ear wire welding device 200 and reducing the noise of the device, an electric cylinder is preferred. The second linear guide 221 selects a linear guide shaft or a linear slide rail, and from the perspective of installation convenience, a linear guide shaft is preferred. The second linear guide 221 includes two pieces, which are respectively connected to the indenter mounting plate 218. The indenter mounting plate 218 is connected to the driving end of the second actuating element 220 through the second floating joint 222. In addition, the first linear guide 215 of the first driving component 206 is also mounted on the indenter mounting plate 218. The two indenters 209 are respectively mounted at the distal ends of the axial direction of the first linear guide 215. Thus, while the second actuating element 220 drives the indenter mounting plate 218 to move up and down, the two indenters 209 move up and down together with the indenter mounting plate 218.

[0037] In this embodiment, since the first driving component 206 and the second driving component 208 act almost simultaneously, one of the guiding members of the driving component can be arranged on the other driving component, which can make the structure more compact.

[0038] Continue to refer to Figure 3 and assist in referring to Figure 2, further, when an electric cylinder is used as the second actuator 220, in order to prevent the electric cylinder from being overloaded after the indenter 209 abuts against the welding head 210, the indenter mounting plate 218 is arranged to be hung on the driving end of the second actuator 220 through the second floating joint 222. A buffer member 223 such as a spring is provided between the indenter mounting plate 218 and the driving end of the second actuator 220. Thus, the indenter mounting plate 218 and the driving end of the second actuator 220 are kept stable in the vertical direction. After the indenter 209 abuts against the welding head 210, even if the electric cylinder continues to be driven, since the output rod of the electric cylinder as the driving end of the second actuator 220 can continue to extend by compressing the buffer member 223, the electric cylinder can be prevented from being overloaded.

[0039] Figure 4 is a perspective view of the ear wire holding assembly 207 and the rotation driving part 227. Refer to Figure 4 , and continue to refer to Figure 1 , in some embodiments, in order to improve the feeding efficiency of the ear wire 102, the ear wire holding assembly 207 is rotatably mounted to the second mounting seat 216. The ear wire holding assembly 207 includes a holding seat 224, and a first rotating shaft 225 is mounted on the holding seat 224. Correspondingly, a bearing 226 is mounted on the second mounting seat 216, and the first rotating shaft 225 is rotatably mounted to the bearing 226. Thus, the ear wire holding assembly 207 can be rotatably mounted to the second mounting seat 216. By rotatably mounting the ear wire holding assembly 207 to the second mounting seat 216, the ear wire 102 can be fed rotatably. While one side of the ear wire 102 of the ear wire holding assembly 207 abuts against the main body portion 101 and is welded, the other side of the ear wire holding assembly 207 can simultaneously perform the operation of loading the ear wire 102. After the welding of the ear wire 102 on one side of the ear wire holding assembly 207 is completed, by rotating the ear wire holding assembly 207, the position of the ear wire holding assembly 207 can be quickly switched. Thus, the welding operation of the ear wire 102 and the loading operation of the ear wire 102 can be performed simultaneously, the production cycle can be shortened, and the feeding efficiency of the ear wire 102 can be improved.

[0040] In some embodiments, in order to easily drive the rotation of the earwire holding component 207, two rotation driving parts 227 are further included. The rotation driving parts 227 are respectively connected to the earwire holding component 207 and respectively drive the earwire holding component 207 to rotate. Specifically, one rotation driving part 227 is connected to one earwire holding component 207, and the other rotation driving part 227 is connected to the other earwire holding component 207. The rotation driving part 227 can be installed either on the second mounting base 216 or on the base 211. In order to make the structure of the earwire holding part 203 more compact, preferably, the rotation driving part 227 is installed on the base 211. The rotation driving part 227 as a driving element can include, for example, a first motor 228. The first motor 228 and the first rotating shaft 225 of the earwire holding component 207 are connected through, for example, a first transmission mechanism 229. The first transmission mechanism 229 can be selected, for example, as a synchronous belt transmission mechanism, a belt transmission mechanism, etc. Thus, the rotation of the earwire holding component 207 can be easily driven. In addition, since the rotation driving part 227 is installed on the base 211 and the earwire holding component 207 will be driven by the first driving component 206 to move up and down, that is, there is a relative movement in the up and down direction between the earwire holding component 207 and the rotation driving part 227. In order to prevent the synchronous belt of, for example, the synchronous belt transmission mechanism from falling off, the length of the synchronous belt can be appropriately increased.

[0041] Figure 5 is Figure 4 a perspective view of the earwire holding component 207 in Figure 5 In order to facilitate observation, the holding seat 224 is partially cut away in Figure 5 and continue to refer to Figure 4, in some embodiments, to easily hold the ear wire 102. Each ear wire holding assembly 207 further includes: two clamping members 230. Among them, the ear wire 102 is attached to the outer periphery 224a of the holding base 224. The two clamping members 230 are respectively mounted to the holding base 224 and can be opened or closed relative to the holding base 224. In the closed state, the clamping members 230 clamp and hold the ear wire 102 on the holding base 224, and in the open state, the clamping members 230 release the ear wire 102. Specifically, the outer periphery of the holding base 224 is substantially arc-shaped so that the rotation radii of the ear wire holding assemblies 207 are substantially the same. Among the two clamping members 230, one clamping member 230 is located on one side of the holding base 224 and is used to clamp the ear wire 102 on one side of the holding base 224. The other clamping member 230 is located on the other side of the holding base 224 and is used to clamp the ear wire 102 on the other side of the holding base 224. The clamping member 230 is rotatably mounted to the holding base 224 through a second rotating shaft 231. In addition, a protrusion 232 is provided on the clamping member 230. Correspondingly, an elastic piece 233 is mounted on the holding base 224, and a ball 234 is placed on the elastic piece 233. The clamping member 230 presses the ball 234 through the protrusion 232 to deform the elastic piece 233, so that the protrusion 232 stably holds in this position after switching positions on both sides of the ball 234. Thereby, it is possible to achieve that the clamping member 230 stably holds in the open state or the closed state.

[0042] Continue to refer to Figure 4 , and refer additionally to Figure 3 、 Figure 5, in some embodiments, in order to easily drive the clamping member 230, the pressing portion 204 further includes a closing driver 235. The closing driver 235 is installed on the second driving assembly 208. When being driven downward by the second driving assembly 208, the closing driver 235 presses the clamping member 230 to close the clamping member 230 relative to the holding seat 224. Specifically, the closing driver 235 can be installed on the pressing head 209 and act simultaneously with the pressing head 209, for example. Among the two clamping members 230, one clamping member 230 (for the sake of convenience of description, also referred to as the first clamping member 230a) is in the closed state, and the first clamping member 230a clamps the end of the ear wire 102 to be welded to the current main body portion 101. The other clamping member 230 (for the sake of convenience of description, also referred to as the second clamping member 230b) is in the open state, and the second clamping member 230b is used to prepare to clamp the end of the ear wire 102 of the next main body portion 101. The ear wire 102 is in a state of continuous wire feeding. While the pressing head 209 presses the ear wire 102 and the main body portion 101 onto the welding head 210 simultaneously for welding, the closing driver 235 presses the second clamping member 230b (it should be noted that at this time, the opening driver 246 described later opens the first clamping member 230a simultaneously). Thus, the second clamping member 230b is closed relative to the holding seat 224 and clamps the ear wire 102 (that is, at this time, the second clamping member 230b clamps the end of the ear wire 102 of the next main body portion 101). After the second clamping member 230b clamps the ear wire 102, the ear wire 102 is cut off by the cutting portion 236 described later. Thus, the clamping member 230 can be easily driven. While completing the welding of the ear wire 102 of the current main body portion 101, by closing the clamping member 230 (that is, the second clamping member 230b), the preparation work for the ear wire 102 of the next main body portion 101 can be quickly completed, the production cycle can be shortened, and thus the production efficiency of the ear wire welding device 200 can be greatly improved.

[0043] Figure 6 is a perspective view of the ear wire holding assembly 207 and the wire releasing portion 237, Figure 7 is Figure 6 a perspective view of the wire releasing portion 237 of Figure 6 、 Figure 7, when the ear wire 102 is clamped by the clamping member 230 in the holding seat 224, when the rotating driving part 227 drives the holding seat 224 to rotate, due to its own tension, the ear wire 102 is wound around the outer circumference 224a of the holding seat 224. After the welding of the ear wire 102 is completed, it is necessary to make the welded ear wire 102 fall off from the holding seat 224. In some embodiments, in order to make the welded ear wire 102 fall off from the holding seat 224, a wire removing part 237 is further included. The wire removing part 237 has a third driving assembly 238 and a wire removing member 239. The wire removing member 239 is connected to the third driving assembly 238 and is driven by the third driving assembly 238 in the up and down direction. When driven downward by the third driving assembly 238, the wire removing member 239 makes the ear wire 102 fall off from the holding seat 224. Specifically, the third driving assembly 238 includes a second motor 240, a second transmission mechanism 241, a third transmission mechanism 242 and a third linear guide 243. Among them, from the perspective of making the structure of the second mounting seat 216 more compact, the second motor 240 is mounted on the base 211. In addition, the third transmission mechanism 242 and the third linear guide 243 are mounted on the second mounting seat 216. The second transmission mechanism 241 selects, for example, a synchronous belt transmission mechanism or a belt transmission mechanism. The third transmission mechanism 242 selects, for example, an eccentric wheel structure, that is, the third transmission mechanism 242 includes an eccentric connecting member 244 and a transmission connecting rod 245. The eccentric connecting member 244 is connected to the second motor 240 through the second transmission mechanism 241 and is driven by the second motor 240 to rotate. One end of the transmission connecting rod 245 is connected to the eccentric connecting member 244, and the other end is connected to the third linear guide 243. The wire removing member 239 is connected to the third linear guide 243. Thus, the second motor 240 converts the rotational motion into a linear motion through the eccentric wheel structure and drives the wire removing member 239 to move up and down. In this embodiment, due to the use of the motor and the eccentric wheel structure, the driving speed of the third driving assembly 238 can be greatly increased, and then the switching speed of the wire removing member 239 can be increased. By increasing the switching speed of the wire removing member 239, the wire removing speed of the ear wire 102 can be increased, the production cycle can be shortened, and further the welding efficiency of the ear wire welding device 200 can be improved.

[0044] In some embodiments, for easy offline operation, the offline portion 237 further includes an opening driving member 246. The opening driving member 246 is connected to the third driving assembly 238 and is driven by the third driving assembly 238 in the up-and-down direction. When driven downward by the third driving assembly 238, the opening driving member 246 presses the clamping member 230, causing the clamping member 230 to open relative to the holding base 224. Specifically, the opening driving member 246 can be connected to a transmission link 245, for example, and move simultaneously with the offline member 239. While the offline member 239 removes the ear wire 102 from the outer periphery 224a of the holding base 224, the opening driving member 246 presses the clamping member 230 (such as the first clamping member 230a described above), whereby the end of the ear wire 102 clamped by the clamping member 230 falls off. By setting the opening driving member 246 to be connected to the third driving assembly 238 and operate simultaneously with the offline member 239, not only can the structure be made more compact, but also since the offline operation and the operation of opening the clamping member 230 are almost simultaneous, the production cycle can be shortened, and the efficiency of the ear wire welding device 200 can be further improved.

[0045] Figure 8 is a perspective view of the ear wire holding assembly 207 and the lead wire assembly 247, refer to Figure 8 and refer additionally to Figure 1 , in some embodiments, for reliable feeding of the ear wire 102, the ear wire holding portion 203 further includes two lead wire assemblies 247. The lead wire assemblies 247 are respectively mounted to the second mounting base 216 and respectively elastically abut against the two holding bases 224 so that the ear wire 102 is fed to the holding bases 224. Specifically, an ear wire feeding device (not shown) can be provided on the base 211. The ear wire feeding device can use a roller driving device for feeding a coiled tape well known in the art. The fed ear wires 102 respectively abut against the two holding bases 224 via the two lead wire assemblies 247. The lead wire assembly 247 includes a lead wire mounting plate 248, a third rotating shaft 249, a lead wire cylinder 250, and a tension spring member 251. Among them, the lead wire mounting plate 248 is mounted to the second mounting base 216 so that the lead wire assembly 247 is mounted to the second mounting base 216. The third rotating shaft 249 is rotatably mounted to the lead wire mounting plate 248. One end of the third rotating shaft 249 is equipped with the lead wire cylinder 250. One end of the lead wire cylinder 250 abuts against the holding base 224. One end of the tension spring member 251 is hooked on the third rotating shaft 249, and the other end is hooked on the lead wire mounting plate 248.
