Description

Technical Field

[0001] This utility model relates to the field of automatic assembly of speaker springs, and more specifically to an automatic machine for bending and assembling speaker springs. Background Technology

[0002] To facilitate automated loudspeaker production and enable automated loudspeaker feeding, the loudspeaker is designed as follows: Figure 1 The material strips are used to connect the base frames of each speaker through the edge strips, which facilitates automatic feeding of the speakers and enables assembly in an automatic assembly machine.

[0003] Traditional material removal methods are mainly based on cutting and punching, which is highly efficient. However, due to the small size of the speaker's base frame and the close proximity of the cutting point to the base frame, the cutting blade is relatively thin and prone to dulling. After dulling, it can cause material jamming, resulting in incompletely removed waste material on the product end, which affects product quality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic machine for bending and assembling speaker springs, which removes waste material from the conveyor belt and avoids frequent replacement of the cutter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic speaker spring bending and assembly machine is disclosed, which transports speakers via a conveyor belt. The machine includes a descrambling mechanism comprising a base frame positioning seat, descrambling grippers, an oscillating unit, and a waste material channel. The base frame positioning seat supports and holds the base frame within the conveyor belt. A pressing structure presses the base frame. The grippers of the descrambling grippers, driven by a first gripper cylinder, hold the waste material from the conveyor belt. The oscillating end of the oscillating unit is connected to the first gripper cylinder to drive it to oscillate up and down. The waste material channel is located below the descrambling grippers to discharge the held waste material.

[0007] Furthermore, the oscillation unit includes a motor, a coupling, and an eccentric disc. The eccentric disc is provided with an eccentric pin. The base of the gripper cylinder in the disassembly gripper is provided with a connecting groove corresponding to the eccentric pin. The eccentric pin is inserted into the connecting groove to drive the disassembly gripper to move up and down.

[0008] Furthermore, it also includes a floating base plate mechanism, which includes a floating base plate and a support block. The floating base plate is slidably disposed above the machine body and supports the base frame positioning seat. The support block supports and adjusts the height of the floating base plate.

[0009] Furthermore, the floating base plate mechanism also includes a transverse shift rod. The upper end of the support block is connected to the center of the floating base plate, and the lower end of the support block passes through the machine body downwards to form an inclined groove. The transverse shift rod includes a transverse shift seat, a crossbar, a transverse shift pin, and a handwheel seat. The transverse shift seat is connected to the lower part of the machine body, the crossbar is slidably connected in the transverse shift seat, and the crossbar is provided with a transverse shift pin corresponding to the inclined groove. The handwheel seat adjusts the transverse shift amount of the crossbar.

[0010] Furthermore, it also includes a cutting mechanism located before the material unloading mechanism. The cutting mechanism includes a blade holder and a lever frame. The blade holder is elastically mounted on the feeding channel by a spring. The blade holder has a cutting edge for the material strip to pass through. One end of the lever frame is connected to a lifting actuator, and the other end of the lever frame is located above the blade holder to press the blade holder.

[0011] Furthermore, it also includes a material transfer mechanism disposed between the cutting mechanism and the dismantling mechanism. The material transfer mechanism includes a sliding base, a material transfer gripper, and a material transfer cylinder. The sliding base is slidably disposed on the machine body along the direction of the feeding channel. The material transfer gripper is mounted on the sliding base and grips the cut material strip. The material transfer cylinder is disposed along the direction of the feeding channel. One end of the material transfer cylinder is connected to the machine body, and the other end drives the sliding base to move the material strip held by the material transfer gripper backward.

[0012] Furthermore, it also includes a feeding mechanism located at the rear end of the dismantling mechanism. The feeding mechanism includes a transfer arm and a feeding gripper unit. The transfer arm has a horizontal transfer unit and a vertical transfer unit. The feeding gripper unit includes a feeding base plate, a plurality of variable pitch slides, a variable pitch cylinder, a variable pitch plate, and a plurality of feeding grippers. The feeding base plate is connected to the vertical transfer unit. The plurality of variable pitch slides are arranged along the width direction of the feeding base plate. Each variable pitch slide is provided with a variable pitch pin. The variable pitch cylinder is connected to the feeding base plate and its output end is connected to the variable pitch plate. The variable pitch plate is provided with a plurality of variable pitch grooves corresponding to each of the variable pitch pins. The plurality of feeding grippers are connected one-to-one to each of the variable pitch slides.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model is equipped with a material dismantling mechanism. The material dismantling mechanism clamps the waste material of the material strip with a gripper, and then the high-frequency oscillation of the oscillation unit causes fatigue fracture at the root of the waste material, thereby separating it from the base frame. Compared with the commonly used cutting method, the gripper oscillation method can dismantle the waste material of multiple stations at one time, and it does not need to be close to the base frame like a cutting tool. Therefore, its structural layout space is easy to adjust, and it does not produce the jamming phenomenon after the cutting tool becomes dull, which makes the waste material effectively separated.

[0015] 2. This utility model features a floating design for the feeding channel and an easily adjustable floating base plate mechanism, which allows for flexible adjustment of the feeding channel's height and facilitates coordinated adjustment between the feeding channel, traction mechanism, and shaping mechanism.

[0016] 3. This utility model is equipped with a cutting mechanism driven by a lever frame. It has a compact structure, can realize dual-path cutting, and improves the reuse rate of components.

[0017] 4. The feeding gripper unit in the feeding mechanism of this utility model can realize the gripper pitch change, thereby solving the transfer problem of inconsistent base frame spacing on the material belt and base frame spacing on the final material tray. Attached Figure Description

[0041] Example

[0042] Please refer to Figure 1 As shown, the base frame 110 of each speaker 100 is connected by an edge strip. The spring 120 is injection molded into the base frame 110 during the injection molding process. Therefore, the strip contains the base frame 110, the spring 120 and the waste material 130 connecting the base frame 110. The edge of the waste material 130 forms a hole, which is used as the traction hole 140 and positioning hole of the strip.

[0043] Please refer to Figure 2 As shown, this utility model discloses an automatic assembly machine for speaker 100 spring 120, used to complete the assembly between spring 120 and base frame 110 as described above. It includes a machine body 200, a feeding channel, a traction mechanism 400, an assembly mechanism 500, a floating base plate mechanism 300, a cutting mechanism 600, a material transfer mechanism 700, a material disassembly mechanism 800, and a material unloading mechanism 900.

[0044] The machine body 200 is equipped with a material rack 210 for mounting a disc-shaped material belt, thereby feeding material into the feeding channel. The feeding channel is mounted on the machine body 200 for conveying the material belt.

[0045] Please refer to Figure 2 and Figure 4 As shown, the traction mechanism 400 is located below the feeding channel. The traction mechanism 400 includes a traction motor 410 and a traction wheel 420 driven by the output end of the traction motor 410. The material belt has traction holes 140 arranged in an array along its length direction, and the traction wheel 420 is provided with traction pins 421 corresponding to the traction holes 140 in its circumferential direction. Thus, when the traction motor 410 drives the traction wheel 420 to rotate, the traction pins 421 distributed in the circumferential direction on the traction wheel 420 will be inserted into the traction holes 140 in sequence, thereby driving the material belt forward.

[0046] Please refer to Figure 3 As shown, the assembly mechanism 500 is located on the feeding channel and is used to complete the fastening of the spring piece 120 on the base frame 110.

[0047] Please refer to Figure 2 and Figure 7 As shown, the cutting mechanism 600 is located at the rear end of the assembly mechanism 500 and is used to cut the continuous strip into segments. For example, if the tray of this invention has a specification of 6 segments per row, it corresponds to cutting the strip into 6 segments per section. The cutting mechanism 600 includes a blade holder 610 and a lever frame 620. The blade holder 610 is elastically mounted on the feeding channel by a spring and has a cutting edge 611 through which the feeding strip passes. One end of the lever frame 620 is connected to the lifting actuator, and the other end of the lever frame 620 is located above the blade holder 610 to press the blade holder 610. The cutting mechanism 600, driven by the lever frame 620, has a compact structure, can achieve dual-path cutting, and improves the reuse rate of components.

[0048] like Figure 2 and Figure 6 As shown, the material transfer mechanism 700 is located at the rear end of the cutting mechanism 600. The material transfer mechanism 700 includes a sliding base 710, a material transfer gripper 720, and a material transfer cylinder 730. The sliding base 710 is slidably mounted on the machine body 200 along the feeding channel direction. The material transfer gripper 720 is mounted on the sliding base 710 and grips the cut strip. The material transfer cylinder 730 is located along the feeding channel direction. One end of the material transfer cylinder 730 is connected to the machine body 200, and the other end drives the sliding base 710 to move the strip held by the material transfer gripper 720 backward. In this way, the material transfer mechanism 700 realizes the function of conveying the segmented strip produced by the cutting mechanism 600 backward.

[0049] like Figure 8 As shown, the unloading mechanism 800 is located at the rear end of the cutting mechanism 600. The unloading mechanism 800 includes a base frame positioning seat 810, unloading grippers 820, an oscillation unit 830, and a waste channel 840. The base frame positioning seat 810 supports the base frame 110 in the material strip held by the transfer grippers 720. The grippers of the unloading grippers 820 hold the waste material 130 of the material strip. The oscillation end of the oscillation unit 830 is connected to the first gripper cylinder to drive it to oscillate up and down. The waste channel 840 is located below the unloading grippers 820 to discharge the waste material 130 held by them. Here, the oscillation unit 830 includes a motor 831, a coupling 832, and an eccentric disk 833. An eccentric pin 8331 is provided on the eccentric disk 833. The base of the gripper cylinder in the unloading gripper 820 is provided with a connecting groove 821 corresponding to the eccentric pin 8331. The eccentric pin 8331 acts on the connecting groove 821 to drive the unloading gripper 820 to move up and down at high frequency.

[0050] The material dismantling mechanism 800 of this utility model uses grippers to hold the waste material 130 of the material strip. Thus, when a pressing structure presses the base frame, the high-frequency up-and-down oscillation of the oscillation unit 830 causes fatigue fracture at the root of the waste material 130, thereby separating it from the base frame 110. Compared with the commonly used cutting method, the gripper oscillation method can dismantle the waste material 130 of multiple stations at one time, and it does not require the cutting blade to be close to the base frame 110 as with the cutting blade. Therefore, its structural layout space is easy to adjust, and it is equivalent to the cutting blade not producing the jamming phenomenon after the cutting blade becomes dull, so that the waste material 130 can always be effectively separated.

[0051] Please refer to Figure 5 As shown, the floating base plate mechanism 300 includes a floating base plate 320, a support block 330, and a transverse rod 340. The floating base plate 320 is slidably mounted above the machine body 200 via guide columns and supports the feeding channel. The upper end of the support block 330 is connected to the center of the floating base plate 320 to support the floating base plate 320, and the lower end of the support block 330 penetrates downward through the machine body 200 to form an inclined groove 331. The transverse shift rod 340 includes a transverse shift seat 341, a crossbar 342, a transverse shift pin 343, and a handwheel seat 344. The transverse shift seat 341 is connected to the lower part of the machine body 200. The crossbar 342 is slidably connected in the transverse shift seat 341. The crossbar 342 is provided with a transverse shift pin 343 corresponding to the inclined groove 331. Thus, the transverse shift amount of the crossbar 342 can be adjusted by rotating the handwheel of the handwheel seat 344, thereby flexibly adjusting the height of the feeding channel and facilitating the coordinated adjustment between the feeding channel and the traction mechanism 400 and the assembly mechanism 500.

[0052] like Figure 9As shown, this utility model also includes a feeding mechanism 900 located at the rear end of the disassembly mechanism 800. The feeding mechanism 900 includes a transfer arm 910 and a feeding gripper unit 920. The transfer arm 910 has a lateral transfer unit 911 and a vertical transfer unit 912. The feeding gripper unit 920 forms the aforementioned pressing structure for pressing the speaker frame in the disassembly mechanism 800. Specifically, it includes a feeding seat plate 921, several pitch-changing slides 922, a pitch-changing cylinder 923, a pitch-changing plate 924, and several feeding grippers 925. The feeding seat plate 921 is connected to the vertical transfer unit 912. The several pitch-changing slides 922 are arranged along the width direction of the feeding seat plate 921. Each pitch-changing slide 922 is provided with a pitch-changing pin 9221. The pitch-changing cylinder 923 is connected to the feeding seat plate 921 and its output end is connected to the pitch-changing plate 924. The pitch-changing plate 924 is provided with several pitch-changing grooves 9241 corresponding to each pitch-changing pin 9221. The several feeding grippers 925 are connected one-to-one to each of the pitch-changing slides 922. Thus, by driving the pitch plate 924 through the pitch cylinder 923, the pitch slide 922 can be slid, thereby changing the distance of the unloading gripper 925 and solving the transfer problem of the inconsistency between the spacing of the base frame 110 on the material strip and the spacing of the base frame 110 on the final material tray.

[0053] The unloading mechanism 900 transports the assembled speaker 100 to the subsequent tray loading mechanism for subsequent processing.

[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
