Description

Technical Field

[0001] This invention belongs to the field of audio equipment manufacturing and material cutting, and relates to a speaker mesh slitting machine for automated speaker production. Background Technology

[0002] A speaker is a device that converts audio signals into sound. Simply put, it refers to a speaker enclosure or subwoofer enclosure with a built-in power amplifier that amplifies the audio signal before it is played back by the speaker itself, making the sound louder. Speakers need ventilation holes to produce sound, which requires a speaker grille. Speaker grilles are not only used on speakers; they are also needed on headphones, speakers, and mobile phone speakers to prevent dust accumulation. Speaker grilles require cutting during manufacturing.

[0003] Patent CN206952254U discloses a speaker grille cutting device, including a worktable; a first fixing plate is welded to the top right side of the worktable, and an adjusting device is welded to the upper left side of the first fixing plate. The adjusting component of the adjusting device is equipped with a cutting device, which is located on the upper left side of the worktable. This invention adjusts the position between the cutter and the speaker grille using the adjusting device, cuts the speaker grille using the cutting device, and fixes the speaker grille using the fixing device. While this device can cut speaker grilles, during the cutting process, the bottom of the speaker grille contacts the top of the worktable, and the cutter easily contacts the top of the worktable during cutting, causing damage. Furthermore, this application can only cut one speaker grille at a time, resulting in low efficiency. Summary of the Invention

[0008] Preferably, the front track straightening assembly includes roller I and track straightening plate. Roller I is symmetrically arranged at the top center of the platform I, and track straightening plate is arranged on the side of roller I near the placement cylinder.

[0009] Preferably, a slotted hole is made in the middle of the track plate, and the position of the slotted hole is recessed towards the middle, with the width of the slotted hole being greater than the thickness of the speaker grille.

[0010] Preferably, the cutting assembly includes a cylinder, a lifting frame, an annular blade, optical axis I and optical axis II. Cylinders are symmetrically arranged on the upper part of the mounting frame, and the output shafts of the cylinders are connected to the lifting frame. A row of annular blades is installed at the bottom of the lifting frame. Optical axis I is installed at the lower part of the lifting frame and is slidably connected to the reinforcing ribs on the left and right walls of the mounting frame. Optical axis II is installed at the upper part of the lifting frame and is slidably connected to the upper part of the mounting frame.

[0011] Preferably, it also includes a pushing assembly. The pushing assembly is connected between the lifting frame and the sliding plate. The pushing assembly includes a telescopic rod, a spring I, and a hinge rod. The telescopic rods are symmetrically arranged on the front and rear sides of the lifting frame. The fixed end and the telescopic end of the telescopic rod are connected by a spring I. The left and right sides of the sliding plate are rotatably provided with hinge rods. The bottom ends of the hinge rods on the same side are rotatably connected, and the bottom end of the telescopic rod is rotatably connected to the hinge rod at the rotatable connection point.

[0012] Preferably, it also includes a rear track straightening assembly. The rear track straightening assembly is provided on the top of the platform II. The rear track straightening assembly includes roller II, a motor and gears. Rollers II are symmetrically arranged on the top of the platform II. Rollers II are parallel to roller I.

[0032] Example 1: A speaker mesh slitting machine for automated speaker production, such as... Figures 1-6 As shown, the system includes a base 1, a platform I2, a platform II3, a placement cylinder 4, a front track assembly 5, a mounting bracket 6, a reinforcing rib 61, a cutting assembly 7, and a support assembly 8. Platforms I2 and II3 are symmetrically arranged on the top of the base 1. Platforms I2 and II3 do not completely cover the top of the base 1. The distance between platforms I2 and II3 is less than the width of platform I2. The width of platforms I2 and II3 is the same as that of the base 1. Platforms I2 and II3 are of equal length, width, and height. The placement cylinder 4 is bolted to the top of platform I2. The axis of the placement cylinder 4 is aligned with that of platform I2. The long side of 2 is parallel. A front straightening component 5 is set on the platform I2 behind the placement cylinder 4. The front straightening component 5 straightens the speaker mesh by extrusion. A mounting frame 6 is connected between the top of the platform I2 and the platform II3. Four reinforcing ribs 61 are installed on the mounting frame 6. Two reinforcing ribs 61 are installed on the left and right walls of the mounting frame 6, and two reinforcing ribs 61 are installed on the upper part of the mounting frame 6. A cutting component 7 is installed on the mounting frame 6. The cutting component 7 cuts the speaker mesh by lifting. Support components 8 are set on the upper side of the platform I2 and the platform II3 below the cutting component 7.

[0033] The operator can apply the corresponding technical solution in this device to the technology of speaker mesh cutting according to the specific situation. When it is necessary to use this device to cut speaker mesh, firstly, put the rolled speaker mesh on the placement cylinder 4, then pass one end of the speaker mesh through the front straightening component 5, and after the speaker mesh is straightened by the front straightening component 5, move it between the cutting component 7 and the support component 8, and then cut the speaker mesh through the cutting component 7. The cut speaker mesh falls through the gap between the table I2 and the table II3.

[0034] like Figure 4 As shown, the front track straight assembly 5 includes a roller I 51 and a track straight plate 52. The roller I 51 is symmetrically arranged at the top center of the platform I 2. The roller I 51 is installed parallel to the placement cylinder 4. The track straight plate 52 is arranged on the side of the roller I 51 near the placement cylinder 4. The track straight plate 52 has a slotted hole in the middle, and the position of the slotted hole is recessed towards the middle. The width of the slotted hole is greater than the thickness of the horn mesh.

[0035] like Figure 5As shown, the cutting assembly 7 includes a cylinder 71, a lifting frame 72, annular blades 73, optical axis I 74, and optical axis II 75. Cylinders 71 with their output shafts facing downwards are symmetrically arranged on the upper part of the mounting frame 6. The output shafts of the cylinders 71 are connected to the lifting frame 72. A row of annular blades 73 is installed at the bottom of the lifting frame 72, with the centers of the annular blades 73 on the same horizontal straight line. Optical axis I 74 is installed at the lower part of the lifting frame 72, and is slidably connected to the reinforcing ribs 61 on the left and right walls of the mounting frame 6. Optical axis II 75 is installed at the upper part of the lifting frame 72, and is slidably connected to the upper part of the mounting frame 6. Both optical axis I 74 and optical axis II 75 are parallel to the output shafts of the cylinders 71.

[0036] like Figure 6 As shown, the support assembly 8 includes a fixed plate 81 and a sliding plate 82. The tops of the tabletop I2 and tabletop II3 are both horizontally connected to the fixed plate 81 via the support plate. The upper surfaces of the fixed plates 81 on both sides are at the same height. The upper surfaces of the fixed plates 81 are slidably connected to the sliding plates 82. The top of the sliding plates 82 has the same number of arc-shaped grooves 83 as the annular blades 73. The arc-shaped grooves 83 are semi-circular and extend to the inner side of the sliding plate 82. When the two sliding plates 82 are closed, the arc-shaped grooves 83 on the sliding plates 82 combine to form a circle.

[0037] like Figure 7 As shown, it also includes a pushing component 9. The pushing component 9 is connected between the lifting frame 72 and the sliding plate 82. The pushing component 9 includes a telescopic rod 91, a spring I 92 and a hinge rod 93. The telescopic rod 91 is symmetrically and vertically arranged on the front and rear sides of the lifting frame 72. The fixed end and the telescopic end of the telescopic rod 91 are connected by a spring I 92. The left and right sides of the sliding plate 82 are rotatably arranged with hinge rods 93. The bottom end of the hinge rod 93 on the same side is rotatably connected, and the bottom end of the telescopic rod 91 is rotatably connected to the hinge rod 93 at the rotatable connection point.

[0038] When the horn mesh passes through the front straightening assembly 5, one end of the horn mesh passes through the slot in the middle of the straightening plate 52. The slot is concave in the middle to facilitate the passage of the horn mesh. After passing through the slot, the horn mesh passes between the rollers I 51. The rollers I 51 straighten the horn mesh. At this time, the control cylinder 71 extends, driving the lifting frame 72 to move downward, which in turn drives the telescopic rod 91 to move downward, thereby driving the hinge end of the hinge rod 93 to move downward, so that the sliding plates 82 close together. After closing, the arc groove 83 on the sliding plate 82 is below the annular blade 73. After the sliding plates 82 close, the lifting frame 72 continues to move downward. At this time, the telescopic rod 91 shortens, the spring I 92 is compressed, and the lifting frame 72 drives the annular blade 73. The device moves downwards to contact the speaker grille and cuts it. Because the arc groove 83 is below the annular blade 73, the annular blade 73 enters the arc groove 83 after cutting the speaker grille. The annular blade 73 will not damage the sliding plate 82, nor will it damage itself. Then, the control cylinder 71 shortens, driving the lifting frame 72 to move upwards, causing the annular blade 73 to move upwards. At the same time, when the lifting frame 72 moves upwards, the spring I 92 resets, driving the telescopic rod 91 to reset. Then, it is pulled, and the hinge end of the hinge rod 93 moves upwards, separating the sliding plates 82. At this time, the cut speaker grille falls through the gap between the table I 2 and the table II 3. After the annular blade 73 moves upwards and resets, the control cylinder 71 stops working.

[0039] like Figure 7 As shown, it also includes a rear track straightening assembly 10. The rear track straightening assembly 10 is provided on the top of the platform II3. The rear track straightening assembly 10 includes a roller II101, a motor 102 and a gear 103. The roller II101 is symmetrically arranged on the top of the platform II3. The roller II101 is parallel to the roller I51. The motor 102 is fixed to the right side of the top of the platform II3 by bolts. The output shaft of the motor 102 is connected to the shaft of the roller II101 below. The left side of the roller II101 is concentrically connected to the gear 103, and the two gears 103 mesh.

[0040] After the horn mesh passes through the front straightening assembly 5 at one end, the control motor 102 rotates intermittently clockwise, driving the lower roller II 101 to rotate clockwise. At the same time, the gear 103 drives the upper roller II 101 to rotate counterclockwise. The arc length of the rotation of the roller II 101 driven by the motor 102 each time is equal to the diameter of the cut horn mesh plus 20mm. When the annular blade 73 cuts the horn mesh, the motor 102 stops rotating. The horn mesh that has passed through the front straightening assembly 5 passes between the rollers II 101. The intermittently rotating rollers II 101 can automatically convey the horn mesh backward and straighten the cut horn mesh, so that the horn mesh can be cut better. After the horn mesh is cut, the control motor 102 stops working.

[0041] like Figure 8 and Figure 9 As shown, it also includes a collection assembly 11. The collection assembly 11 is installed in the middle of the base 1. The collection assembly 11 includes a collection frame 111, guide rods 112, limiting plates 113, springs II 114, and limiting rings 115. The collection frame 111 is placed above the middle of the base 1. The collection frame 111 partially overlaps with the platform I 2 and platform II 3 in the vertical direction. Guide rods 112 are symmetrically arranged on the left and right walls above the middle of the base 1. Limiting rings 115 are slidably arranged on the guide rods 112. The limiting rings 115 are positioned between the base 1 and the base 1. All are connected to springs II 114, which are sleeved on guide rods 112. Limiting plates 113 are rotatably installed on the front limiting rings 115. The inner side of the limiting plate 113 contacts the side of the collection frame 111. The limiting plate 113 above the rear guide rod 112 has a slot 116. The width of the slot 116 is smaller than the diameter of the limiting ring 115 and larger than the diameter of the guide rod 112. The rear guide rod 112 passes through the slot 116, and the limiting ring 115 on the rear guide rod 112 is outside the limiting plate 113.

[0042] like Figure 10 As shown, it also includes an L-shaped rod 12 and a protrusion 13. The protrusion 13 is provided on the upper left side of the collection frame 111. The bottom end of the telescopic rod 91 on the left side is connected to the L-shaped rod 12. The bottom end of the L-shaped rod 12 is semi-circular, and the lower part of the L-shaped rod 12 faces the direction of the protrusion 13. The lower part of the L-shaped rod 12 and the protrusion 13 overlap in the vertical direction.

[0043] The cut speaker grille falls into the collection frame 111 through the gap between tabletop I2 and tabletop II3. When the telescopic rod 91 moves downward, it drives the L-shaped rod 12 downward. When the L-shaped rod 12 moves downward and contacts the protrusion 13, the protrusion 13 moves to the right, causing the collection frame 111 to move to the right. This pushes the right-side limiting plate 113 to move to the right, compressing the right-side spring II 114. After the L-shaped rod 12 leaves the protruding end of the protrusion 13, the spring II 114 resets, causing the limiting plate 113 to reset, causing the collection frame 111 to move to the left and reset. When the telescopic rod 91 moves upward, it drives the L-shaped rod 12 upward, and the L-shaped rod 12 contacts the protrusion 13 again. The collection frame 111 repeats the above actions. Because the left side of the collection frame 111 is equipped with the spring II 114 and the limiting plate 113, the collection frame 111 can shake when it moves left and right, so that the speaker grille inside the collection frame 111 will not accumulate in one place.
