Description

Technical fields:

[0001] This utility model relates to the field of automation, and specifically refers to a quick-change sticker machine. Background technology:

[0002] The voice coil is the core driving component of an electrodynamic loudspeaker's vibration system (also known as a mechanical wave system), often referred to as the "heart" of the loudspeaker. Essentially, it is a coil that carries audio current, and its performance directly determines the loudspeaker's key acoustic characteristics, including sound pressure level frequency response, sound pressure level, impedance curve, distortion, transient response, loudspeaker parameters, and ultimately, sound quality. Crucially, the voice coil's performance is closely related to the loudspeaker's power handling capacity and lifespan. The voice coil mainly consists of a frame, a coil wound around the frame, and reinforcing paper used to strengthen the frame. In the voice coil's manufacturing process, the proper attachment of the reinforcing paper to the coil is a critical step.

[0003] Chinese utility model patent CN 221836427 U discloses an automatic voice coil sticker machine, comprising a machine base, a feeding mechanism, a feeding mechanism, and a sticker cutting mechanism. The feeding mechanism supplies reinforcing paper to the feeding mechanism; the feeding mechanism conveys reinforcing paper to the sticker cutting mechanism; the sticker cutting mechanism includes a paper winding mechanism, a cutting mechanism, and a pressing mechanism. The paper winding mechanism includes a rotating support, a cylindrical main shaft, a main shaft drive motor, and a tensioning assembly. The tensioning assembly includes a tensioning sleeve, a movable shaft, a mounting bracket, a tensioning drive cylinder, and a tensioning rod. The diameter of the tensioning rod gradually increases from its head end to its tail end. An arc-shaped clamping spring portion is evenly extended on one end face of the tensioning sleeve. The cutting mechanism can cut the reinforcing paper; when the paper winding mechanism winds the reinforcing paper onto the voice coil frame, the pressing mechanism can press the reinforcing paper firmly onto the voice coil frame. There is no need to connect air pipes to the cylindrical spindle, avoiding situations where air pipes twist or become entangled in the equipment, reducing equipment energy consumption, decreasing equipment maintenance frequency, and improving production efficiency.

[0004] In the aforementioned patents, manual assistance is required for loading and unloading the voice coil frame, which not only affects production efficiency but also introduces significant errors in manual quality inspection, easily leading to low yield rates. Secondly, the tensioning sleeve used to position the voice coil frame cannot be quickly replaced and is often only used for producing one size of voice coil, resulting in poor versatility. Given the frequent updates and replacements of loudspeaker products on the market, producing only one voice coil size undoubtedly increases the production burden on companies.

[0005] In view of the above, the inventors propose the following technical solution. Utility model content:

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fast mold changing sticker machine.

The bushing is provided with multiple locking through holes for the balls to pass through.

[0009] Furthermore, in the above technical solution, the inner wall of the operating sleeve is provided with an inner ring block for confining the ball within the locking through hole. One side of the inner ring block is provided with a retraction cavity for the ball to exit the locking position on the shaft, and the inner ring block is provided with an inclined surface on the side of the retraction cavity.

[0010] Furthermore, in the above technical solution, a positioning sleeve for limiting the spring is also provided on the shaft, wherein the spring is located between the inner ring block and the positioning sleeve.

[0011] Furthermore, in the above technical solution, the bearing seat is floatingly installed inside the base, and at least one floating spring is provided between the base and the bearing seat.

[0012] Furthermore, in the above technical solution, the feeding mechanism includes a first Y-axis moving module vertically arranged on one side of the production line, a Y-axis rotating module arranged on the first Y-axis moving module, a first Z-axis moving module arranged on the Y-axis rotating module, and a first picking claw arranged on the first Z-axis moving module for gripping the voice coil skeleton.

[0013] Furthermore, in the above technical solution, the first detection device includes a second Y-axis moving module perpendicular to the rotational transposition mechanism, a first transmission roller rotatably disposed on the second Y-axis moving module and capable of contacting and pressing against the end of the voice coil frame, a first detector disposed above the first transmission roller and used to detect the quality of the voice coil frame, and a first motor disposed on the second Y-axis moving module and used to drive the first transmission roller to rotate the voice coil frame.

[0014] Furthermore, in the above technical solution, the sticker mechanism includes a rotary drive device disposed beside the rotary switching mechanism and capable of vertically pressing against the end of the voice coil skeleton, a sticker device disposed beside the rotary drive device and used to attach the reinforcing paper to the voice coil skeleton, and a rolling device disposed above the rotary drive device and used to press the reinforcing paper firmly onto the voice coil skeleton.

[0015] Furthermore, in the above technical solution, the sticker-applying device includes a lifting platform, a first X-axis moving module disposed on the lifting platform, a third Y-axis moving module disposed on the first X-axis moving module, a roll of material disposed on the third Y-axis moving module for providing reinforcing paper, and a material transfer module disposed on the third Y-axis moving module for transferring reinforcing paper.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] 1. In this utility model, the voice coil skeleton is picked up from the production line by the feeding mechanism and transferred to the positioning fixture of the rotary transfer mechanism. The rotary transfer mechanism drives the positioning fixture to rotate and pass through the first detection device, the sticker mechanism and the discharge mechanism in sequence. The first detection device then performs quality inspection on the voice coil skeleton. Subsequently, the sticker mechanism pastes the reinforcing paper onto the voice coil skeleton. Finally, after the second detection device detects the effect of the reinforcing paper pasting, the discharge mechanism removes the voice coil skeleton from the positioning fixture and places it back onto the production line. This realizes that the reinforcing paper is automatically pasted onto the voice coil skeleton without manual intervention, which is highly efficient and low-cost.

[0019] 2. In this utility model, a ball bearing is installed on the bushing to lock and fix the shaft. When the shaft is inserted into the bushing, the operating sleeve pushes the ball bearing into the annular groove of the shaft under the push of the spring, thereby locking the shaft. When disassembling the shaft, the operating sleeve is pushed to slide away from the pressure on the ball bearing, and then the shaft is pulled out from the bushing. Since the ball bearing has lost the limit of the operating sleeve, the shaft can be pulled out and the ball bearing can be pushed back into the locking through hole, thus achieving smooth removal. Similarly, when inserting the shaft into the bushing, it is also necessary to push the operating sleeve away from the limit of the ball bearing. Attached image description:

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figures 1 to 6As shown, a quick mold-changing sticker machine includes: a production line 1 for transferring a voice coil skeleton A; a rotary shifting mechanism 2 disposed beside the production line 1; a feeding mechanism 3 and a discharging mechanism 4 disposed between the rotary shifting mechanism 2 and the production line 1; a first detection device 5 disposed beside the rotary shifting mechanism 2 for detecting the quality of the voice coil skeleton A; and a sticker-applying mechanism 6 disposed beside the rotary shifting mechanism 2 for applying reinforcing paper. The rotary shifting mechanism 2 is equipped with multiple positioning fixtures 21 for horizontally positioning the voice coil skeleton A. The feeding mechanism 3, the first detection device 5, the sticker-applying mechanism 6, and the discharging mechanism 4 are sequentially distributed around the rotary shifting mechanism 2. A second detection device 7 for detecting the quality of the sticker is disposed beside the discharging mechanism 4. The voice coil frame A is picked up from the production line 1 by the feeding mechanism 3 and transferred to the positioning fixture 21 of the rotary transfer mechanism 2. The rotary transfer mechanism 2 drives the positioning fixture 21 to rotate and pass through the first detection device 5, the sticker mechanism 6 and the discharge mechanism 4 in sequence. The first detection device 5 then performs quality inspection on the voice coil frame A. Subsequently, the sticker mechanism 6 pastes the reinforcing paper onto the voice coil frame A. Finally, after the second detection device 7 detects the effect of the reinforcing paper pasting, the discharge mechanism 4 removes the voice coil frame A from the positioning fixture 21 and places it back onto the production line 1. This achieves automatic pasting of the reinforcing paper onto the voice coil frame A without manual intervention, resulting in high efficiency and low cost.

[0028] The positioning fixture 21 includes a base 211, a bearing seat 212 disposed on the base 211, a bushing 213 rotatably mounted in the bearing seat 212, a bearing 214 disposed between the bushing 213 and the bearing seat 212, a shaft 215 detachably mounted in the bushing 213 for mounting the voice coil frame A, and multiple balls 216 disposed on the outer wall of the bushing 213 for locking and fixing the shaft 215. An operating sleeve 217 is slidably mounted on the bushing 213 and used to push the ball 216 to lock onto the shaft body 215, and a spring 218 is mounted on the bushing 213 and used to push the operating sleeve 217 to keep pressing the ball 216. One end of the shaft body 215 can extend into the bushing 213 and is provided with an annular groove 215A for matching and locking with the ball 216. The bushing 213 is provided with a plurality of locking through holes 213A for the ball 216 to pass through. A ball bearing 216 is installed on the bushing 213 to lock and fix the shaft 215. When the shaft 215 is inserted into the bushing 213, the operating sleeve 217 pushes the ball bearing 216 into the annular groove 215A of the shaft 215 under the push of the spring 218, thereby locking the shaft 215. When disassembling the shaft 215, the operating sleeve 217 is pushed to slide away from the pressure on the ball bearing 216, and then the shaft 215 is pulled out from the bushing 213. Since the ball bearing 216 has lost the limit of the operating sleeve 217, the ball bearing 216 can be pushed back into the locking through hole 213A when the shaft 215 is pulled out, so that it can be pulled out smoothly. Similarly, when inserting the shaft 215 into the bushing 213, the operating sleeve 217 also needs to be pushed away from the limit of the ball bearing 216.

[0029] The inner wall of the operating sleeve 217 is provided with an inner ring block 217A for confining the ball 216 within the locking through hole 213A. One side of the inner ring block 217A is provided with a retraction cavity 217B for allowing the ball 216 to retract from its locking position against the shaft 215. An inclined surface 217C is provided on the side of the inner ring block 217A adjacent to the retraction cavity 217B. Through the retraction cavity 217B on one side of the inner ring block 217A, the ball 216 can be pushed back into the retraction cavity 217B during the insertion and removal of the shaft 215. Furthermore, through the inclined surface 217C on one side of the inner ring block 217A, when the spring 218 pushes the operating sleeve 217 back to its original position, the inclined surface 217C can push the ball 216 into the locking through hole 213A.

[0030] A positioning sleeve 219 for limiting the spring 218 is also provided on the shaft 215, wherein the spring 218 is located between the inner ring block 217A and the positioning sleeve 219. The positioning sleeve 219 is fixed to the shaft 215 with screws. The positioning sleeve 219 limits the spring 218, so that the spring 218 maintains the force exerted by the spring on the operating sleeve 217. The positioning sleeve 219 also presses against the end of the spring 218 to prevent the spring 218 from directly pressing against the bearing 214.

[0031] The bearing housing 212 is floatingly mounted inside the base 211, and at least one floating spring 210 is provided between the base 211 and the bearing housing 212. By providing a floating spring 210 between the base 211 and the bearing housing 212, and by installing the bearing housing 212 in the base 211 with a clearance fit, the bearing housing 212 can swing slightly up, down, left, and right, which facilitates the fitting of the voice coil frame A onto the shaft 215.

[0032] The feeding mechanism 3 includes a first Y-axis moving module 31 vertically disposed on one side of the production line 1, a Y-axis rotating module 32 disposed on the first Y-axis moving module 31, a first Z-axis moving module 33 disposed on the Y-axis rotating module 32, and a first picking claw 34 disposed on the first Z-axis moving module 33 for gripping the voice coil skeleton A. One end of the feeding mechanism 3 is provided with a baffle device 7 extending onto the production line 1 for intercepting and positioning the voice coil skeleton A. During operation, the first Y-axis moving module 31, the Y-axis rotating module 32, and the first Z-axis moving module 33 work together to drive the first picking claw 34 to move vertically above the production line 1 to grab the voice coil skeleton A. Then, the first Y-axis moving module 31, the Y-axis rotating module 32, and the first Z-axis moving module 33 work together to drive the first picking claw 34 to move to the side of the positioning fixture 21 and swing the voice coil skeleton A to a horizontal position to fit onto the shaft 215 of the positioning fixture 21, thereby realizing the feeding of the voice coil skeleton A.

[0033] The first detection device 5 includes a second Y-axis moving module 51 perpendicular to the rotational transposition mechanism 2, a first transmission roller 52 rotatably mounted on the second Y-axis moving module 51 and capable of contacting and pressing against the end of the voice coil frame A, a first detector 53 mounted above the first transmission roller 52 for detecting the quality of the voice coil frame A, and a first motor 54 mounted on the second Y-axis moving module 51 for driving the first transmission roller 52 to rotate the voice coil frame A. During operation, the second Y-axis moving module 51 pushes the first transmission roller 52 to press against the end of the voice coil frame A. The first motor 54 drives the first transmission roller 52 to rotate the voice coil frame A, allowing the first detector 53 to scan the voice coil frame A once for detection. The end of the first transmission roller 52 is made of a flexible material, which not only avoids hard contact with the voice coil frame A but also increases the frictional force of contact with the voice coil frame A, facilitating the rotation of the voice coil frame A.

[0034] The sticker-applying mechanism 6 includes a rotary drive device 61 located beside the rotary switching mechanism 2 and capable of vertically pressing against the end of the voice coil frame A; a sticker-applying device 62 located beside the rotary drive device 61 and used to apply reinforcing paper to the voice coil frame A; and a rolling device 63 located above the rotary drive device 61 and used to press the reinforcing paper firmly onto the voice coil frame A. The rotary drive device 61 has the same structure as the first detection device 5, and can drive the voice coil frame A to rotate, cooperating with the sticker-applying device 62 to deliver the reinforcing paper around the frame. The rolling device 63 presses against the joint between the reinforcing paper and the voice coil frame A using rollers, ensuring a tight fit between the reinforcing paper and the voice coil frame A during rotation. After the reinforcing paper is applied around the voice coil frame A, a cutter on one side of the rollers cuts the reinforcing paper.

[0035] The sticker applicator 62 includes a lifting platform 621, a first X-axis moving module 622 mounted on the lifting platform 621, a third Y-axis moving module 623 mounted on the first X-axis moving module 622, a reel 624 mounted on the third Y-axis moving module 623 for providing reinforcing paper, and a transfer module 625 mounted on the third Y-axis moving module 623 for transferring the reinforcing paper. The front end of the sliding seat 623A in the third Y-axis moving module 623 is provided with an arc surface 623B for pressing against the voice coil frame A. During operation, the reinforcing paper is pulled from the reel 624, transferred by the transfer module 625, and positioned above the arc surface 623B. The third Y-axis moving module 623 then contacts and adheres the arc surface 623B to the voice coil frame A, thus attaching the reinforcing paper to the voice coil frame A.

[0036] The unloading mechanism 4 includes a material-removing device 41 located below the second detection device 7 for removing the voice coil skeleton A from the positioning fixture 21, an X-axis rotation device 42 located between the material-removing device 41 and the production line 1, a second Z-axis moving module 43 located on the X-axis rotation device 42, and a second picking claw 44 located on the second Z-axis moving module 43 for gripping the voice coil skeleton A. After the second detection device 7 completes the detection of the voice coil skeleton A, the material-removing device 41 removes the voice coil skeleton A from the positioning fixture 21, and the second Z-axis moving module 43 drives the second picking claw 44 to take over the voice coil skeleton A. The X-axis rotation device 42 and the second Z-axis moving module 43 work together to drive the second picking claw 44 to place the voice coil skeleton A back onto the production line 1.

[0037] In summary, during operation, the voice coil skeleton A is vertically placed on the production line 1 and transferred to the feeding mechanism 3. The voice coil skeleton A is intercepted by the blocking device 7, which has a scissor-shaped V-shaped slot. Further, the feeding mechanism 3 removes the voice coil skeleton A from the production line 1 and moves it to the positioning fixture 21 of the rotary positioning mechanism 2. The rotary positioning mechanism 2 drives the positioning fixture 21 to rotate and switch positions, sequentially docking with the first detection device 5, the sticker mechanism 6, and the discharge mechanism 4. Further, when the voice coil skeleton A moves to the first detection device... When the voice coil frame A is rotated around one revolution by the first detection device 5, it is inspected to ensure that the voice coil frame A is of qualified quality. Further, when the voice coil frame A moves to the sticker mechanism 6, the sticker mechanism 6 attaches reinforcing paper around the voice coil frame A. Further, when the voice coil frame A moves to the discharge mechanism 4, the voice coil frame A is first inspected by the second detection device 7 to determine whether the reinforcement paper on the voice coil frame A meets the requirements. The discharge mechanism 4 then places qualified and unqualified voice coil frames A into different areas of the production line 1 for subsequent processing.
