Description

Technical Field

[0001] The utility model relates to the technical field of voice coil processing equipment, in particular to an appearance detection device for voice coil coils. Background Art

[0002] A voice coil is a coil through which current passes in a loudspeaker and is an important part of the mechanical wave system of an electro-dynamic loudspeaker. It can also be said to be the heart of the loudspeaker. The voice coil mainly consists of a bobbin and a coil. After the coil is wound around the bobbin, a 360° appearance inspection needs to be carried out on the coil to prevent defective products with wear or breakage on the coil from flowing out. In the existing production process, generally, the voice coil after winding the coil is sleeved on a cylindrical jig 91 as shown in the attachment Figure 1 to position the voice coil, facilitate the appearance inspection of the coil, and weld cotton threads at both ends of the coil after the appearance inspection is completed. At present, the appearance inspection of the voice coil coil needs to be observed by the naked eye of workers. The workers rotate the cylindrical jig 91 to drive the voice coil to rotate 360° while observing the appearance of the coil. This inspection method has a cumbersome operation process, wastes manpower, increases labor costs, and it is easy to miss inspection and misjudgment due to human judgment, which is likely to cause defective products to flow out.

[0019] Refer to Figures 1 - 5 。

[0020] The utility model provides an appearance detection device for a voice coil coil, which comprises a workbench. A turntable mechanism 1, a feeding station 2, a visual inspection station 3, a defective product picking station 4, a non-defective product picking station 5 and a display screen 6 are arranged on the workbench. The turntable mechanism 1 comprises a divider 10 arranged on the workbench, a turntable 11, a plurality of spindle mechanisms 12 evenly distributed on the turntable 11, and a spindle rotation driving mechanism 13 arranged on the turntable 11. The divider 10 comprises a cylindrical output shaft 100. The cylindrical output shaft 100 penetrates through the center of the turntable 11 and is fixedly connected with the turntable 11. The spindle rotation driving mechanism 13 comprises a support column 130 fixedly connected to the top of the workbench and passing through the cylindrical output shaft 100, a sliding seat 131 fixedly connected to the top end of the support column 130, a slider 132 slidably connected to the sliding seat 131, a first driving cylinder 133 arranged on the sliding seat 131 and drivingly connected to the slider 132, a spindle driving motor 134 arranged on the slider 132, and a contact head 135 drivingly connected to the spindle driving motor 134. The spindle mechanism 12 comprises a rotating seat 120 arranged on the turntable 11 and a spindle 121 rotatably connected to the rotating seat 120 and arranged along the radial direction of the turntable 11. The feeding station 2 is used for assembling the voice coil onto the spindle 121. The visual inspection station 3 is used for visually inspecting the appearance of the voice coil coil. The display screen 6 is used for displaying the images captured by the visual inspection station 3. The defective product picking station 4 is used for picking out defective products with defective appearance from the spindle 121. The non-defective product picking station 5 is used for picking out non-defective products with good appearance from the spindle 121.

[0021] The specific working principle is as follows. After being processed at the previous station, the voice coil can be sleeved on the cylindrical jig 91 and conveyed to the side of the feeding station 2 to prevent the voice coil from deforming and facilitate appearance inspection. The spindle 121 should be set to match the cylindrical jig 91. The cylindrical jig 91 sleeved with the voice coil is installed on the spindle 121 through the feeding station 2. The divider 10 drives the turntable 11 to rotate, so that the voice coil moves to the visual inspection station 3. The first driving cylinder 133 drives the slider 132 to move forward, so that the contact head 135 abuts against the tail end of the spindle 121. The spindle driving motor 134 drives the spindle 121 to rotate, so as to drive the voice coil to rotate 360°. During the rotation of the voice coil, the visual inspection station 3 inspects the appearance of the coil on the voice coil, and the display screen 6 displays the images captured by the visual inspection station 3 to judge whether the current voice coil is a non-defective product or a defective product. If the current voice coil is a defective product, the defective product picking station 4 can pick out the defective product with defective appearance from the spindle 121. If the current voice coil is a non-defective product, the non-defective product picking station 5 can pick out the non-defective product with good appearance from the spindle 121. The automatic detection of the appearance of the voice coil coil can be realized, which greatly saves manpower, reduces production costs, improves production efficiency and avoids the outflow of defective products.

[0022] Based on the above embodiments, a material pushing station 7 is further provided on the workbench. The material pushing station 7 includes a first vertical plate 70 provided on the workbench, a material pushing cylinder 71 provided on the first vertical plate 70, and a push head 72 drivingly connected to the material pushing cylinder 71. The material pushing cylinder 71 is arranged along the radial direction of the turntable 11. After the cylindrical jig 91 sleeved with a voice coil is installed on the main shaft 121 at the loading station 2, the turntable 11 is driven to rotate by the indexing cam 10 so that the current voice coil moves to the material pushing station 7. The material pushing cylinder 71 drives the push head 72 to move forward to assemble the cylindrical jig 91 onto the main shaft 121 in place, preventing the cylindrical jig 91 from falling off the main shaft 121.

[0023] Based on the above embodiments, a defective product discharging station 4 is further provided on the workbench. The defective product discharging station 4 includes a discharging groove 80 fixedly connected to the bottom of the workbench, a discharging channel 81 penetrating through the workbench and leading to the inside of the discharging groove 80, a discharging cylinder 82 provided at one end of the discharging groove 80, and a pushing block movably arranged in the discharging groove 80 and drivingly connected to the discharging cylinder 82. After the cylindrical jig 91 sleeved with a voice coil with appearance defects is removed from the main shaft 121 at the defective product picking station 4, the defective product picking station 4 then drops the cylindrical jig 91 into the discharging groove 80 through the discharging channel 81. The discharging cylinder 82 drives the pushing block to move forward, and the pushing block can push the cylindrical jig 91 out along the discharging groove 80, facilitating the discharge of defective products.

[0024] Based on the above embodiments, a cutting plate 9 is fixedly connected to one side of the workbench. A V-shaped cutting opening 90 is provided at one end of the cutting plate 9.

When the horizontal linear driving device 22 works, it can drive the pneumatic three-jaw chuck 27 to move horizontally. When the rotary cylinder 23 works, it can drive the pneumatic three-jaw chuck 27 to swing longitudinally. When the picking driving cylinder 26 works, it can drive the pneumatic three-jaw chuck 27 to move back and forth, facilitating the pneumatic three-jaw chuck 27 to grasp and place products.

[0026] Based on the above embodiments, the vision inspection station 3 includes an upper vision mechanism 30, a lower vision mechanism 31, and a light source mechanism 32. The upper vision mechanism 30 includes a gantry 300 disposed on the workbench and a first CCD camera 301 disposed on the gantry 300.
