Description

Technical Field

[0001] The invention belongs to the technical field of loudspeaker production equipment, in particular to an assembly equipment for loudspeaker production. Background Art

[0002] A speaker is a device that converts electrical signal energy into sound energy and can radiate sound energy to a limited space (such as a room) or outdoor space. It is commonly known as a horn. The speaker is composed of a fixed permanent magnet, a coil and a conical paper cone. There are electric and electromagnetic types, and they are divided into built-in speakers and external speakers. When the speaker is working, an alternating current whose size and direction change with time passes through the coil. It is used to play music, language and other signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest component in the audio equipment, but for the sound effect, it is the most important component.

[0003] In current loudspeaker designs, the assembly between the frame and the diaphragm is usually done by gluing, mechanical connection or hot pressing. The most common method is to evenly coat the inner bottom wall of the loudspeaker frame with polyurethane glue by a gluing mechanism, and then convey the frame to the next process by a conveyor belt. The operator of the next process first inserts the diaphragm center column into the center hole of the diaphragm, and then mounts the diaphragm to the inner bottom wall of the frame by holding the upper end of the diaphragm center column, thereby achieving bonding between the frame and the diaphragm. After the installation is completed, the bonding quality between the diaphragm and the frame is usually verified by manual or simple visual inspection.

[0004] However, this method has some obvious problems: first, manual inspection is prone to omissions and cannot fully and accurately evaluate the bonding condition of each unit, especially the uniformity of glue distribution. Too much or too little glue is often difficult to detect in time. Second, manual inspection is sensitive to environmental factors (such as changes in temperature and humidity), which may cause fluctuations in assembly quality and affect sound quality. At the same time, due to the lack of real-time feedback mechanism, these potential problems can usually only be discovered during later testing or rework, resulting in low production efficiency and increased costs. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides an assembly equipment for speaker production, which has the advantages of improving efficiency and ensuring product quality through automated gluing, robot assembly and CT scanning quality inspection.

[0006] To achieve the above object, the present invention provides the following technical solution: an assembly device for speaker production, comprising a mounting frame, a servo motor is fixedly mounted on the right side of the front of the mounting frame by bolts, and a conveying mechanism for conveying speaker frame parts is arranged on the inner side of the mounting frame;

The control unit sends a first control instruction to the adjustment unit, and the adjustment unit adjusts the glue application amount of the glue application mechanism accordingly.

[0012] S3. If the thickness deviation is greater than 0, it means that the glue bonding quality is unqualified and the amount of glue applied needs to be reduced.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the present invention.

[0052] like Figures 1 to 15 As shown, the present invention provides an assembly device for speaker production, including a mounting frame 1, a servo motor 2 is fixedly installed on the right side of the front of the mounting frame 1 by bolts, and a conveying mechanism for conveying speaker frame parts is provided on the inner side of the mounting frame 1;

[0053] A glue coating mechanism for coating the inner bottom wall of the loudspeaker frame part with a glue layer and a manipulator for assembling the diaphragm center column part, the diaphragm part and the loudspeaker frame part into a finished part group are sequentially arranged from right to left above the moving path of the conveying mechanism;

[0054] It also includes a data acquisition unit 6, an analysis and processing unit 7, a control unit 8 and an adjustment unit 9, wherein:

[0055] When the conveying mechanism drives the finished parts group to move along the moving path of the conveying mechanism, the data acquisition unit 6 scans and detects the glue bonding quality on the contact surface of the diaphragm part and the speaker frame part in the finished parts group to reconstruct the two-dimensional image data of the glue bonding quality, and sends the two-dimensional image data to the analysis and processing unit 7, and uses the attenuation formula to reversely infer the actual glue layer thickness, and compares the actual glue layer thickness with the preset target thickness to calculate the thickness deviation, and judges whether the glue coating amount of the glue coating mechanism needs to be adjusted based on the thickness deviation result. The specific adjustment steps are:

[0056] S1. If the thickness deviation is 0, it means that the glue bonding quality of the contact surface between the diaphragm and the speaker frame is qualified, and the current state is maintained. The analysis and processing unit 7 generates an analysis result and sends it to the control unit 8. At this time, the control unit 8 does not issue an instruction to the adjustment unit 9;

[0057] S2. If the thickness deviation is less than 0, it indicates that the glue bonding quality is unqualified and the glue application amount needs to be increased. The analysis and processing unit 7 calculates the adjusted glue application amount and generates an analysis result and sends it to the control unit 8. The control unit 8 sends a first control instruction to the adjustment unit 9, and the adjustment unit 9 adjusts the glue application amount of the glue application mechanism accordingly.

[0058] S3. If the thickness deviation is greater than 0, it means that the glue bonding quality is unqualified and the amount of glue applied needs to be reduced. The analysis and processing unit 7 calculates the adjusted amount of glue applied and generates an analysis result and sends it to the control unit 8. The control unit 8 sends a second control instruction to the adjustment unit 9, and the adjustment unit 9 adjusts the amount of glue applied by the gluing mechanism accordingly.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the conveying mechanism includes a meshing gear 3, a synchronous toothed belt 31 and a conveying plate 32. The servo motor 2 drives the meshing gear 3 to mesh with the synchronous toothed belt 31, and drives the speaker frame parts placed on the conveying plate 32 to be conveyed horizontally from right to left along the length direction of the mounting frame 1.

[0060] The conveying mechanism also includes a connecting shaft 33 that is rotatably sleeved in the mounting hole of the mounting frame 1 and is symmetrically distributed. The symmetrical distribution of the connecting shaft 33 helps to balance the load of the conveying mechanism, reduces the risk of mechanical deformation or failure caused by excessive force on one side, and ensures stability and durability during long-term operation. The meshing gears 3 are divided into two groups, two by two, and are fixedly sleeved on the two connecting shafts 33 at both ends of the inner side of the mounting frame 1. The output shaft of the servo motor 2 is fixedly connected to one end of one of the connecting shafts 33 through a coupling. When the servo motor 2 drives one of the connecting shafts 33 to rotate, the other connecting shaft 33 is driven to rotate synchronously with it through the meshing of the meshing gear 3 and the synchronous toothed belt 31. This method can provide higher transmission efficiency and reduce Less energy loss, compared with the traditional one-way drive or complex power transmission device, it has a better power transmission effect. In addition, due to the coordinated transmission of the meshing gear 3 and the synchronous toothed belt 31, the conveying mechanism can be more stable during operation, reducing vibration and impact force, thereby improving the stability and reliability of the conveying mechanism when conveying the speaker frame parts, and extending the service life of the mechanical parts. The outer surface of the synchronous toothed belt 31 is provided with slots distributed in a curved drive array, and the conveying plate 32 is inserted into the slots of the synchronous toothed belt 31. A rotating motor 34 is embedded and installed at the center of the upper surface of the conveying plate 32. The output shaft of the rotating motor 34 is fixedly installed with a positioning plate 35 through a coupling, and the outer surface of the upper protruding end of the positioning plate 35 is provided with a tightening component;

[0061] The tightening assembly includes mounting grooves 36 which are opened on the outer surface of the protruding end above the positioning and placement plate 35 and are distributed in a circular array. A spring 361 is fixedly installed on the inner wall of the mounting groove 36. A semicircular top ball 362 is fixedly connected to one end of the spring 361. The speaker frame part is placed on the outer side of the protruding end above the positioning and placement plate 35 through the tightening assembly. The outer surface of the top ball 362 is in tight contact with the inner wall of the speaker frame part under the action of the elastic force of the spring 361.

[0062] like Figure 1 , Figure 2 as well as Figure 7 As shown, the gluing mechanism and the manipulator are both located above the mounting frame 1, and the gluing mechanism includes a first induction switch 4, a gluing machine 41, and a first cylinder 42. When the synchronous toothed belt 31 drives the speaker frame part to move, after the first induction switch 4 senses the speaker frame part, the servo motor 2 drives the synchronous toothed belt 31 to stop moving. At the same time, the gluing machine 41 is driven by the first cylinder 42 to descend along the height of the mounting frame 1, and a glue layer is applied to the inner bottom wall of the speaker frame part.

[0063] The glue coating mechanism also includes a first support frame 43 installed above the mounting frame 1, the first cylinder 42 is fixedly sleeved in the mounting hole of the first support frame 43 by bolts, one end of the piston rod of the first cylinder 42 is fixedly connected to a lifting plate 44, and the glue coating machine 41 is fixedly installed on the front of the lifting plate 44. Under the premise of ensuring the normal operation of the first cylinder 42, a sliding sleeve connection method can be adopted between the lifting plate 44 and the shell of the first cylinder 42. This method can effectively reduce the friction of the lifting plate 44 during the lifting process and provide a smooth lifting movement. When the first cylinder 42 drives the piston rod to move, the lifting plate 44 can stably slide up and down following the movement of the cylinder to avoid lifting and lowering due to excessive friction, ensuring that the glue coating machine 41 can stably coat the inner bottom wall of the speaker frame parts, and the first induction switch 4 is fixedly installed on the mounting frame 1 above the left side of the support frame;

[0064] Electrode sheets 45 with insulating sleeves are fixedly installed on the upper part of the inner bracket of the mounting frame 1 and on the lower surface of the conveying plate 32. The two electrode sheets 45 located on the upper part of the inner bracket of the mounting frame 1 are respectively located at the center directly below the gluing mechanism and the data acquisition unit 6. The servo motor 2 cooperates with the synchronous belt 31 through the meshing gear 3 to drive the speaker frame parts to move to directly below the glue coating machine 41. Then, one of the electrode sheets 45 located on the upper part of the inner bracket of the mounting frame 1 contacts the electrode sheet 45 on the lower surface of the conveying plate 32 to power the rotating motor 34, driving the speaker frame parts above the positioning plate 35 to rotate around the axis of the rotating motor 34, thereby enabling the glue coating machine 41 to apply a glue layer to different positions of the inner bottom wall of the speaker frame parts.

[0065] like Figure 1 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 as well as Fig.13As shown, the manipulator includes a second cylinder 5, a clamping jaw 51, a displacement motor 52 and a loading platform 53. The displacement motor 52 drives the second cylinder 5 and the clamping jaw 51 to move horizontally from back to front along the thickness direction of the mounting frame 1. After moving to the top of the loading platform 53, the second cylinder 5 drives the clamping jaw 51 to descend along the height direction of the loading platform 53, and the clamping jaw 51 is used to clamp the diaphragm center column part on the loading platform 53. Through the cooperation of the second cylinder 5 and the displacement motor 52, the clamping jaw 51 drives the diaphragm center column part to be inserted into the diaphragm part hole on the loading platform 53 to achieve assembly action, so as to obtain a semi-finished parts group. Through the cooperation of the second cylinder 5, the displacement motor 52 and the clamping jaw 51 again, the semi-finished parts group after assembly is driven to be assembled on the inner bottom wall of the speaker frame part through the glue layer, so as to obtain a finished parts group.

[0066] The manipulator also includes a second support frame 54 fixedly mounted above the mounting frame 1, and the front inner wall and the rear inner wall of the second support frame 54 are rotatably sleeved with a displacement screw 55, and the displacement motor 52 is fixedly mounted on the back of the second support frame 54, and the output shaft of the displacement motor 52 is fixedly connected to one end of the displacement screw 55 through a coupling, and the outer surface of the displacement screw 55 is threadedly connected with a displacement block 56 slidably sleeved with the inner wall of the second support frame 54, and the second cylinder 5 is fixedly mounted on the lower surface of the displacement block 56, and one end of the piston rod of the second cylinder 5 is fixedly connected to a mounting block 57, and a worm 58 driven by a motor is fixedly mounted on the inner top wall of the mounting block 57, and the electric energy is converted into mechanical energy by the motor to drive the worm 58 to perform circular motion, and one end of the worm 58 is meshed with a symmetrically distributed toothed worm wheel 59, and the inner wall of the mounting block 57 is rotatably sleeved with a symmetrically distributed clamping shaft 510, and the worm wheel 59 is fixedly sleeved on the middle end surface of the clamping shaft 510. The clamping jaws 51 are symmetrically fixedly sleeved on both ends of the clamping shaft 510. The one-way transmission characteristics of the worm gear 59 and the worm 58 can prevent the clamping jaws 51 from loosening or reversing during the grasping process. When the manipulator grasps the diaphragm center column and inserts it into the diaphragm mounting hole, the design of the worm gear 59 and the worm 58 ensures the fixed state of the clamping jaws 51, avoiding loosening or retreating during the grasping process, thereby improving stability and reliability. In addition, the clamping shaft 510 is driven by the worm gear 59 and the worm 58, so that the clamping jaws 51 can be stably fixed at both ends, and the symmetrical design of the clamping jaws 51 helps to ensure uniform distribution of clamping force. In this way, the clamping jaws 51 can provide stable and consistent clamping force when grasping the diaphragm center column, avoiding loose or uneven clamping. At the same time, in order to prevent the clamping jaws 51 from damaging the diaphragm center column when clamping it, a rubber cushion sleeve is provided on the inner arc surface of the clamping jaw 51, which has been drawn in the figure;

[0067] The loading platform 53 is fixedly installed on the front side of the mounting frame 1, and the lower surface of the loading platform 53 is in contact with the ground, and the upper surface of the loading platform 53 is respectively fixedly installed with a first slide rail group and a second slide rail group, and the first slide rail group and the second slide rail group are distributed in parallel above the loading platform 53, and the first slide rail group is composed of two symmetrically distributed first slide rails 511, and a first loading box 512 is hinged between the opposite surfaces of the two first slide rails 511 through a pin shaft, and the two sides of the first loading box 512 are hinged to the first slide rails 511 through the pin shaft, so that the first loading box 512 can move smoothly along the first slide rails 511, and the hinged structure of the pin shaft allows the first loading box 512 to perform smooth arc motion, while avoiding the first loading box 512 being too loose. In order to solve the problem of jamming or unsmooth movement caused by excessive friction, the front and back sides of the first loading box 512 are slidably sleeved with the inner wall of the slide groove of the first slide rail 511.

Indicates thickness deviation, It indicates the initial glue application amount, that is, the glue application amount planned before the deviation is taken into account.

[0076] The working principle and use process of the present invention:

[0077] Step 1, with respect to the loading and unloading of the conveying plate 32 and the loading method of the speaker frame parts, the movement process is as follows: first, the speaker frame parts are conveyed to the designated feeding position by an external conveying mechanism; secondly, the speaker frame parts located at the feeding position are adsorbed to the top of the positioning placement plate 35 of the conveying plate 32 by an external mechanical arm, and the inner wall of the speaker frame parts is pressed and contacted by the cooperation of the spring 361 and the top ball 362, so as to realize the continuous feeding of the speaker frame parts; finally, the conveying plate 32 is automatically loaded and unloaded by the cooperation of the lifting mechanism and another conveying mechanism; at the same time, in the present application, since the specific structures and detailed working processes of the mechanical arm, the conveying mechanism and the lifting mechanism can be realized by adopting the existing technology, they will not be described in detail here;

[0078] Step 2, the control unit 8 controls the servo motor 2 to start, and the servo motor 2 drives the meshing gear 3 to mesh with the synchronous toothed belt 31, driving the loudspeaker frame parts placed on the conveying plate 32 to be conveyed horizontally from right to left along the length direction of the mounting frame 1. When the synchronous toothed belt 31 drives the loudspeaker frame parts to move, after the first induction switch 4 senses the loudspeaker frame parts placed above the positioning plate 35, the servo motor 2 drives the synchronous toothed belt 31 to stop moving. At the same time, the first cylinder 42 drives the glue coating machine 41 to descend along the height of the mounting frame 1, and a glue layer is applied to the inner bottom wall of the loudspeaker frame parts. At the same time, one of the electrode sheets 45 located above the inner side bracket of the mounting frame 1 contacts the electrode sheet 45 on the lower surface of the conveying plate 32 to power the rotating motor 34, driving the loudspeaker frame parts above the positioning plate 35 to rotate with the axis of the rotating motor 34 as the center, so that the glue coating machine 41 can apply a glue layer to different positions of the inner bottom wall of the loudspeaker frame parts.

[0079] Step 3, after the glue coating is completed, the synchronous toothed belt 31 continues to move the speaker frame parts. After the fifth induction switch 525 senses the speaker frame parts above the positioning placement plate 35, the servo motor 2 drives the synchronous toothed belt 31 to stop moving again. At the same time, the control unit 8 controls the displacement motor 52 and the first push cylinder 514 to start. The displacement motor 52 drives the displacement screw 55 to rotate. The displacement screw 55 is connected to the displacement block 56 by a thread, and the second cylinder 5 is driven to move from back to front along the length direction of the displacement screw 55. The first push cylinder 5 14 drives the first push plate 515 to extend in the feeding channel above the loading platform 53, and pushes the diaphragm parts in the first stacking cylinder 513 from the bottom of the first stacking cylinder 513 to the designated feeding position, and then controls the second push cylinder 523 to start, and the second push cylinder 523 drives the second push plate 524 to extend in the feeding channel above the loading platform 53, and pushes the diaphragm center column parts in the second stacking cylinder 522 from the bottom of the second stacking cylinder 522 to the designated feeding position, at which time, the diaphragm center column parts are located in front of the diaphragm parts;

[0080] After the second induction switch 526 senses the displacement block 56, the displacement motor 52 stops working, and the second air cylinder 5 starts to drive the clamping jaw 51 to descend along the height direction of the loading platform 53. The worm 58 driven by the motor makes a circular motion, driving the worm 58 to engage with the worm wheel 59, and driving the clamping jaw 51 to clamp the diaphragm center column part on the loading platform 53. At this time, the second air cylinder 5 performs a complete contraction action, and the displacement motor 52 reverses, driving the second air cylinder 5 to move from front to back along the length direction of the displacement screw rod 55. After the third induction switch 527 senses the displacement block 56, the displacement motor 52 stops working, and the second air cylinder 5 starts to drive the second air cylinder 5 to move from front to back along the length direction of the displacement screw rod 55. The cylinder 5 starts to drive the clamping jaw 51 to descend along the height direction of the loading platform 53, so that the clamping jaw 51 drives the diaphragm center column part to be inserted into the diaphragm part hole on the loading platform 53 to realize the assembly action, and a semi-finished part group is obtained. The displacement motor 52 continues to drive the second cylinder 5 to move from front to back along the length direction of the displacement screw rod 55. After the limit switch 528 senses the displacement block 56, the displacement motor 52 stops working, and the second cylinder 5 starts to drive the clamping jaw 51 to descend along the height direction of the loading platform 53, driving the semi-finished part group after assembly to be assembled on the inner bottom wall of the speaker frame part through the glue layer, and a finished part group is obtained.

[0081] Step 4, when the synchronous toothed belt 31 drives the finished parts group to move along the moving path of the synchronous toothed belt 31, after the fourth induction switch 61 senses the finished parts group, it controls the X-ray emitter 62 to emit an X-ray beam to penetrate the glue layer on the contact surface between the diaphragm parts and the speaker frame parts in the finished parts group, and then the detector 63 receives the X-rays penetrating from the inside of the glue layer, and reconstructs a two-dimensional image of the glue bonding quality according to different absorption rates. At the same time, the electrode sheet 45 located above the inner bracket of the mounting frame 1 contacts the electrode sheet 45 on the lower surface of the conveying plate 32, providing power to the rotating motor 34, driving the speaker frame parts above the positioning plate 35 to rotate precisely around the axis of the rotating motor 34, thereby realizing high-precision, non-destructive detection of different positions of the contact surface between the diaphragm and the speaker frame in the finished parts group using CT scanning technology, which can not only comprehensively evaluate the uniformity, thickness and potential defects such as bubbles of the glue layer, but also generate detailed two-dimensional images, which helps to accurately locate problems in the production process, ensure that the glue bonding quality meets the standards, and thus improve production efficiency and quality control level;

[0082] The acquired two-dimensional image data is sent to the analysis and processing unit 7, and the actual glue layer thickness is inferred using the attenuation formula. The actual glue layer thickness is compared with the preset target thickness to calculate the thickness deviation, and the thickness deviation result is used to determine whether the glue coating amount of the glue coating machine 41 needs to be adjusted.
