Description

[0001] The invention relates to the field of speaker welding processing, and in particular to a three-dimensional stacked headphone speaker array batch welding device. Background Art

[0002] At present, soldering technology is commonly used to achieve the connection of key components of headset speakers, specifically, soldering operations are performed on pins extending from the inside of the speaker.

[0003] These pins that lead out from the inside of the speaker play the role of transmitting electrical signals. In order to ensure the stability and reliability of signal transmission, high requirements are placed on the welding quality. During the soldering process, given the material characteristics of the pins and the mechanical strength and electrical performance standards that the welding parts need to achieve, the solder joint area is relatively large. This means that in order to ensure the welding quality during actual welding operations, it is often necessary to repeat spot welding two or three times for each soldering point.

[0004] However, since each electric welding releases heat and the welding points are relatively concentrated, when welding the same speaker, the heat will continue to accumulate and conduct to the inside of the speaker. The speaker is equipped with permanent magnets that have strict requirements on the magnetic field environment. Their magnetic properties are closely related to the temperature. Once too much heat is generated due to welding and the temperature rises beyond the appropriate range, the permanent magnet will be thermally disturbed and the magnetic force will irreversibly decay. The permanent magnet with weakened magnetic force will not be able to provide a stable and accurate magnetic field environment for the speaker, which will directly interfere with the speaker's sound performance, causing the core acoustic indicators such as the frequency response and sensitivity of the sound to deviate from the normal standards, ultimately affecting the quality of the headset speaker. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a three-dimensional stacked headphone speaker array batch welding device, which can effectively solve the problem in the prior art that in the traditional conventional means of welding speakers, a soldering machine is usually used to act on the four welding points on the speaker at the same time to complete the welding process at one time.

[0013] Furthermore, the fixing mechanism includes a placing seat, the lower end of which is symmetrically fixedly connected to two bottom rods, the limiting frame is fixedly connected to two bottom rails matching the bottom rods, the bottom rods are detachably connected to the corresponding bottom rails, and the bottom rods and the bottom rails slide with each other, the bottom rods and the bottom rails are commonly connected with an anti-falling component, the placing seat is connected with a connecting component near the central end of the variable diameter disk, the placing seat is slidably connected with a clamping seat, the clamping seat is evenly provided with a plurality of mounting grooves along its length direction, the mounting grooves are connected with the clamping components, and the placing seat and the limiting frame are commonly connected with a limiting component at one end away from the variable diameter disk.

[0014] Furthermore, the anti-falling component includes a No. 1 arc-shaped magnet, which is fixedly connected to the bottom rod, and a No. 2 arc-shaped magnet which attracts the No. 1 arc-shaped magnet is fixedly connected to the bottom rail.

[0015] Furthermore, the connecting assembly includes a folding rod, one end of which is fixedly connected to the placement seat, and the other end of the folding rod is fixedly connected to a cylindrical slider at the lower end surface, and the cylindrical slider is slidably arranged in the volute groove, and the bottom of the cylindrical slider is rollingly connected to a ball to facilitate its sliding in the volute groove.

[0016] Furthermore, the clamping assembly includes a mounting seat, which is rotatably connected in a mounting groove, and a circular magnet that attracts the permanent magnet inside the speaker is fixedly connected inside the mounting seat, and a positioning ring is fixedly connected to the upper end surface of the mounting seat, and a notch for positioning is provided on the positioning ring. At the same time, a chamfer is provided on the inner wall of the positioning ring to facilitate the speaker to slide down, and a rotating module is commonly connected to the mounting seat and the limit frame.

[0017] Furthermore, the rotating module includes a gear ring, which is fixedly sleeved on the side wall of the mounting seat, and a rack matching the gear ring is fixedly connected to the inner side wall of the mounting seat.

[0018] Furthermore, the limiting component includes a slot, a slot is provided at one end of the horizontal section of the placement seat and away from the variable diameter disk, the lower end of the clamping seat is fixedly connected with a plug plate, the end surface of the plug plate away from the variable diameter disk and the end surface of the slot away from the variable diameter disk are provided with mutually attractive magnetic stickers to ensure that the two are in contact with each other in the initial state, and the horizontal section of the limit frame is provided with a rectangular slot running through the upper and lower parts, and a locking block is slidably connected in the rectangular slot, and the locking block includes a rectangular block, the rectangular block is slidably connected in the rectangular slide groove up and down, the upper end surface of the rectangular block is fixedly connected with a trapezoidal block and a stopper, and the distance between the trapezoidal block and the variable diameter disk is closer than the stopper, the lower end surface of the placement seat is fixedly connected with a wedge block matching the trapezoidal block, the lower end of the locking block is fixedly connected with a reset spring, the lower end of the reset spring is fixedly connected to the folding plate, and the folding plate is fixedly connected to the lower end of the limit frame.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The welding method adopted by the present invention is different from the general four-point synchronous welding method. It is single-point, alternating welding. After the first soldering point of multiple speakers located on the same clamping seat is welded, the second soldering point is not welded immediately. Instead, the speaker is rotated 360 degrees intermittently and multiple times by an intermittent rotating mechanism, and then the second soldering point is welded, so as to reserve cooling time for the speaker. The above welding method can cool down the speaker without affecting the welding efficiency, and effectively avoid the heat accumulation caused by continuous multi-point welding. Problems such as unstable solder joint quality and thermal damage to components; during the rotation of the above-mentioned limit frame, due to the shape characteristics of the vortex groove, the placement seat and the limit frame will slide relative to each other through the cylindrical slider and the folding rod, while the clamping seat and the speaker thereon are relatively stationary under the restriction of the plug plate and the locking block, and then the speaker is driven to rotate a certain angle through the rotating assembly to achieve point switching. Since the four soldering points on the speaker are often arranged in an arc shape, this method of switching soldering points is more accurate in aligning the welding gun and the soldering point than the traditional method of moving the welding gun in a straight line.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Example:

[0035] See also Figure 1-Figure 9 , a three-dimensional stacked headphone speaker array batch welding equipment, comprising:

[0036] The driving part 1 comprises a base 11 , a central axis is fixedly connected to the base 11 , a reduction motor 12 is fixedly connected to the base 11 , and an intermittent rotation mechanism 13 is connected to the upper end of the reduction motor 12 .

[0037] The conveying part 2 includes a center disk 21, which is fixedly mounted on the center shaft and connected to the intermittent rotation mechanism 13. A plurality of limit frames 22 are evenly fixedly connected to the center disk 21 along the circumferential direction. A fixing mechanism 23 is detachably connected to the limit frames 22, and a diameter reducing mechanism 24 is connected to the center shaft.

[0038] The welding part 3 includes a mounting frame 31, the upper end of the central axis is connected to the mounting frame 31, and the mounting frame 31 is connected to a soldering machine 32 (the soldering machine 32 is a non-standard device, such as Figure 1 as shown in , including multiple soldering guns corresponding to the speakers).

[0039] The variable diameter mechanism 24 includes a variable diameter disc 241, which is fixedly sleeved on the top of the central axis. The upper end surface of the variable diameter disc 241 is provided with a volute groove 242 that matches the fixing mechanism 23 (the number of soldering points of the speaker in the embodiment is four, so the number of turns of the volute groove 242 is slightly less than four turns, so that the loading point and the unloading point are misaligned, and the volute groove 242 is arranged in a clockwise direction), the inner port and the outer port of the volute groove 242 are misaligned, and the position of the inner port is the loading point a (see Figure 3 ), the unloading point b is located in front of the external port in the clockwise direction, and the loading point a is located in front of the unloading point b in the clockwise direction, and the mounting bracket 31 is located at the welding point c, which is set in front of the loading point a in the clockwise direction.

[0040] During the specific implementation, the pins extending from the inside of the speaker to be welded are first manually arranged so that they are located on the corresponding welding points, and then multiple speakers are placed one by one on the fixing mechanism 23 at a specific angle. When the reduction motor 12 is running, the intermittent rotation mechanism 13 will drive the center disk 21, the limit frame 22 and the fixing mechanism 23 to rotate intermittently together. During the intermittent static intervals of the three, the staff will place the fixing mechanism 23 together with the speaker on the limit frame 22 at the loading point a (for the convenience of description, the speaker located on the fixing mechanism 23 is named m speaker, and the speaker on the fixing mechanism 23 behind it in the clockwise direction is named n speaker). Subsequently, when the center disk 21 and the limit frame 22 rotate, the m speaker will be driven to rotate synchronously clockwise along the spiral groove 242 toward the welding point c. After reaching the welding point c, the m speaker stops for the first time, and the soldering machine 32 descends to solder the first soldering point on the m speaker.

[0041] After the first welding is completed, the soldering machine 32 moves up and resets. At this time, the m speaker continues to rotate clockwise with the fixing mechanism 23, and the n speaker moves to the welding point c. The soldering machine 32 welds the first soldering point on the speaker to complete the cycle. When the m speaker rotates 360 degrees cumulatively, it will reach the welding point c for the second time. At this time, the fixing mechanism 23 will slide from the innermost circle of the spiral groove 242 to the secondary outer circle. Since the radius of the secondary inner circle of the spiral groove 242 is larger than the diameter of the innermost circle, the fixing mechanism 23 slides on the limit frame 22 in the direction away from the variable diameter disk 241.

[0042] During this process, the relative position between the m speaker and the limit frame 22 on which it is installed remains unchanged, but it will rotate at a certain angle when it is fixed by the fixing mechanism 23. The rotation of the m speaker will not stop until it returns to the welding point c for the second time. At this time, the second soldering point of the m speaker is rotated to a position aligned with the soldering machine 32. At this time, when the driving unit drives the soldering machine 32 to move downward, the second soldering point of the m speaker will be automatically welded. This process is repeated, and when the m rotates 360 degrees each time to reach the bottom of the soldering machine 32, it will automatically rotate at a fixed angle to automatically switch the soldering point. After each welding of the m speaker, as it is clamped and rotated, its own temperature will also be reduced under the influence of the surrounding air, so as to avoid the weakening of the magnetism of the permanent magnet due to continuous welding for too long.

[0043] When the speaker reaches the bottom of the soldering machine 32 for the fourth time and is soldered by the soldering machine 32, the end of the fixing mechanism 23 close to the reducing disk 241 is also located at the outermost circle of the vortex groove 242. When it continues to rotate clockwise, when it reaches the unloading point b, it will automatically disengage from the vortex groove 242, so that the staff can take the fixing mechanism 23 out of the limiting frame 22.

[0044] The intermittent rotation mechanism 13 includes a cam 131, which is fixedly sleeved on the upper end of the driving shaft of the reduction motor 12. A notch is provided on the cam 131. A contact block 132 is fixedly connected to the upper end surface of the cam 131. A groove wheel 133 is rotatably sleeved on the central axis. A plurality of grooves 134 that match the cam 131 are evenly provided on the groove wheel 133 along the circumferential direction, and the number of the grooves 134 is the same as the number of the limit frame 22. A straight groove 135 that matches the contact block 132 is provided on the groove wheel 133 and located between two adjacent arc-shaped grooves 134. The upper end of the groove wheel 133 is fixedly connected to the center disk 21 through a connecting ring.

[0045] During specific implementation, the reduction motor 12 drives the shaft to rotate, driving the cam 131 to rotate, and the contact block 132 also rotates synchronously with the rotation of the cam 131. The contact block 132 will cycle in and out of the straight groove 135 during the rotation, thereby driving the groove wheel 133 to rotate intermittently. The intermittent rotation of the groove wheel 133 will drive the center disk 21 and the limit frame 22 to rotate synchronously and intermittently through the connecting ring, thereby realizing the intermittent rotation of the fixing mechanism 23.

[0046] The fixing mechanism 23 includes a placement seat 231, and two bottom rods 232 are symmetrically fixedly connected to the lower end of the placement seat 231, and two bottom rails 233 matching the bottom rods 232 are fixedly connected to the limiting frame 22, and the bottom rods 232 are detachably connected to the corresponding bottom rails 233, and the bottom rods 232 and the bottom rails 233 slide with each other, and the bottom rods 232 and the bottom rails 233 are commonly connected with an anti-falling component 234, and the placement seat 231 is connected with a connecting component 235 near the central end of the variable diameter disk 241, and the placement seat 231 is slidably connected with a clamping seat 236, and a plurality of mounting grooves 2361 are evenly opened on the clamping seat 236 along its length direction, and a clamping component 237 is connected in the mounting groove 2361, and a limiting component 238 is commonly connected to the placement seat 231 and the end of the limiting frame 22 away from the variable diameter disk 241.

[0047] The anti-falling component 234 includes a first arc-shaped magnet 2341 , which is fixedly connected to the bottom rod 232 , and a second arc-shaped magnet 2342 which attracts the first arc-shaped magnet 2341 is fixedly connected to the bottom rail 233 .

[0048] The connecting component 235 includes a folding rod 2351, one end of which is fixedly connected to the placement seat 231, and the other end of the folding rod 2351 and the position located at the lower end surface is fixedly connected with a cylindrical slider 2352, and the cylindrical slider 2352 is slidably set in the volute groove 242, and the bottom of the cylindrical slider 2352 is rollingly connected with a ball 2353 to facilitate its sliding in the volute groove 242.

[0049] The clamping assembly 237 includes a mounting seat 2371, which is rotatably connected in the mounting groove 2361. The mounting seat 2371 is fixedly connected inside with a circular magnet 2372 that attracts the permanent magnet inside the speaker. The upper end face of the mounting seat 2371 is fixedly connected with a positioning ring 2373, and the positioning ring 2373 is provided with a notch for positioning. At the same time, the inner wall of the positioning ring 2373 is provided with a chamfer to facilitate the sliding of the speaker. The mounting seat 2371 and the limit frame 22 are commonly connected with a rotating module 2374.

[0050] The rotating module 2374 includes a gear ring 23741 , which is fixedly sleeved on the side wall of the mounting seat 2371 , and a rack 23742 matching the gear ring 23741 is fixedly connected to the inner wall of the placement seat 231 .

[0051] The limiting component 238 includes a slot 2381, and a slot 2381 is provided at one end of the horizontal section of the placement seat 231 and away from the variable diameter disk 241. The lower end of the clamping seat 236 is fixedly connected with a plug plate 2382. The end surface of the plug plate 2382 away from the variable diameter disk 241 and the end surface of the slot 2381 away from the variable diameter disk 241 are provided with mutually attractive magnetic stickers to ensure that the two are attached to each other in the initial state. The horizontal section of the limit frame 22 is provided with a rectangular slot 2383 from top to bottom, and a locking block 23 is slidably connected in the rectangular slot 2383. 84, the locking block 2384 includes a rectangular block, which is slidably connected in the rectangular slide groove, the upper end surface of the rectangular block is fixedly connected with a trapezoidal block and a stop block, and the distance between the trapezoidal block and the variable diameter disk 241 is closer than the stop block, the lower end surface of the placement seat 231 is fixedly connected with a wedge block 2385 that matches the trapezoidal block, the lower end of the locking block 2384 is fixedly connected with a return spring 2386, the lower end of the return spring 2386 is fixedly connected with a folding plate 2387, and the folding plate 2387 is fixedly connected to the lower end of the limit frame 22.

[0052] In specific implementation, when installing the m speaker on the fixing mechanism 23, it is necessary to first place the m speaker in the positioning ring 2373. Under the action of the circular magnet 2372, the lower end of the m speaker is tightly fitted on the mounting seat 2371. Then, it is necessary to adjust the angle of the m speaker so that its four soldering points are aligned with the notches on the positioning ring 2373. Then, the fixing mechanism 23 as a whole together with the m speaker thereon is placed on the limiting frame 22. During the placement process, it is necessary to ensure that the two bottom rods 232 are aligned with the two bottom rails 233, and it is necessary to ensure that the cylindrical slider 2352 is located in the inner port of the volute groove 242. In this state, the plug plate 2382 is located between the trapezoidal block and the stopper, and there is a certain distance between the wedge block 2385 and the trapezoidal block (see FIG. 2 ). Fig. 9 (see the figure above), the first arc magnet 2341 and the second arc magnet 2342 attract each other.

[0053] Afterwards, when the m speaker and the limit frame 22 rotate clockwise from the loading point a to the welding point c along with the center disk 21, since the cylindrical slider 2352 slides from the inner circle to the outer circle in the vortex groove 242, it will drive the placement seat 231 to slide in the limit frame 22 in the direction away from the diameter-changing disk 241 through the folding rod 2351. At this time, under the action of the magnetic sticker, the placement seat 231 and the plug plate 2382 are in a connected state, and the plug plate 2382 and the clamping seat 236 will slide synchronously with the sliding of the placement seat 231. When the m speaker rotates clockwise to the welding point c, the end of the plug plate 2382 away from the diameter-changing disk 241 just fits into the stopper.

[0054] After the soldering machine 32 completes the soldering of the first soldering point on the m speaker, as the limit frame 22 continues to rotate clockwise, the cylindrical slider 2352 will continue to slide clockwise in the spiral groove 242. During this process, the placement seat 231 will continue to slide along the limit frame 22 in a direction away from the diameter-changing disk 241, but the insert plate 2382 is blocked by the block and cannot slide synchronously with the placement seat 231, so the insert plate 2382 will be separated from the slot 2381 (see FIG. Fig. 9 As shown in the figure in the middle, during the sliding of the placement seat 231, relative sliding will occur between the clamping seat 236, and then the gear ring 23741 will rotate driven by the rack 23742, driving the m speaker to rotate synchronously. When the m speaker rotates 360 degrees and returns to the welding point c again, the rotation angle of the m speaker can just align its second soldering point with the soldering machine 32, thereby realizing the automatic switching of the m speaker welding point c.

[0055] After the four soldering points of the m speaker are welded in the above manner, the cylindrical slider 2352 also slides to the outermost circle of the spiral groove 242. Then, as the limit frame 22 where the m speaker is located continues to rotate clockwise, the wedge block 2385 will contact the trapezoidal block on the locking block 2384 and drive the locking block 2384 to slide downward (during this period and before, the first arc magnet 2341 and the second arc magnet 2342 are always in a state of mutual attraction to prevent the locking block 2384 and the wedge block 2385 from contacting and causing the placement seat 231 to tilt), until the stopper on the locking block 2384 moves down to below the lowermost end of the plug plate 2382 (see Fig. 9 Located in the figure below), at this time, the arc magnet No. 1 2341 and the arc magnet No. 2 2342 are misaligned with each other. When the limit frame 22 where the m speaker is located slides to the outer end of the volute groove 242, it can slide out of the volute groove 242 from the outer end of the volute groove 242. At this time, as the limit frame 22 continues to move, it will drive the placement seat 231 to slide along the outer wall of the variable diameter disk 241, and finally make it completely separated from the variable diameter disk 241, so that the staff can take it out from the limit frame 22.

[0056] It is worth mentioning that the above three-dimensional stacked headphone speaker array batch welding equipment has the following advantages:

[0057] Advantage 1. In this embodiment, multiple limit frames 22 are fixedly connected to the center disk 21 in a circular array. A placement seat 231 is slidably provided on the limit frame 22 in a detachable connection manner. The placement seat 231 can clamp multiple speakers at the same time through the clamping seat 236 and the clamping assembly 237. When the reduction motor 12 is running, the intermittent rotation mechanism 13 will drive the center disk 21 and the limit frame 22 to rotate intermittently, thereby continuously transporting the speaker to the location of the soldering machine 32, so as to facilitate the soldering machine 32 to weld it. This circular arrangement is relatively compact and can save the equipment's floor space.

[0058] Advantage 2. In the traditional conventional means of welding speakers, a soldering machine 32 is usually used to act on the four welding points on the speaker at the same time to complete the welding process at one time. This welding method will cause the speaker to heat up rapidly due to heat accumulation, which may cause damage to the internal permanent magnet. Different from this, as mentioned above, the welding method of this embodiment is single-point, alternating welding. After the first soldering point of multiple speakers located on the same clamping seat 236 is completed, the second soldering point is not welded immediately. Instead, it is driven by the intermittent rotation mechanism 13 to rotate 360 ​​degrees, and then the second soldering point is welded, thereby reserving cooling time for the speaker. The above welding method can cool the speaker without affecting the welding efficiency, and effectively avoid problems such as unstable solder joint quality and thermal damage to components caused by heat accumulation from continuous multi-point welding.

[0059] Advantage 3: As described above, after the first point welding of the multiple speakers on the same clamping seat 236 is completed, as the limit frame 22 continues to rotate clockwise, the cylindrical slider 2352 will continue to slide clockwise in the volute groove 242. During this process, the placement seat 231 will continue to slide along the limit frame 22 in the direction away from the variable diameter disk 241, but the plug plate 2382 is blocked by the block and cannot slide synchronously with the placement seat 231. Therefore, the plug plate 2382 will be separated from the slot 2381. During the sliding of the placement seat 231, it will cause mutual contact with the clamping seat 236. The gear ring 23741 will slide and then rotate driven by the rack 23742, driving the speaker to rotate synchronously. When the speaker rotates 360 degrees and returns to the welding point c again, the rotation angle of the speaker can just align its second soldering point with the soldering machine 32. At this time, the automatic switching of the speaker welding point c is realized. Since the four soldering points on the speaker are often arranged in an arc shape, this method of switching soldering points is compared with the traditional method of moving the soldering machine 32 in a straight line. The alignment of the soldering machine 32 and the soldering point is more accurate.

[0060] Advantage 4. In this embodiment, after the welding of the four soldering points of the speaker is completed, the cylindrical slider 2352 will also slide to the outermost circle of the vortex groove 242. As the limit frame 22 where the speaker is located continues to rotate clockwise, the wedge block 2385 will contact the trapezoidal block on the locking block 2384 and drive the locking block 2384 to slide downward) until the stop block on the locking block 2384 moves down to below the lower end of the plug plate 2382. When the limit frame 22 where the speaker is located slides to the outer port of the vortex groove 242, it can slide out of the vortex groove 242 from the outer port of the vortex groove 242. At this time, as the limit frame 22 continues to move, it will drive the placement seat 231 to slide along the outer wall of the guide plate, and finally make it completely separate from the reducing disk 241, so that the staff can take it out of the limit frame 22.
