Description

Technical Field

[0001] This utility model belongs to the technical field of speaker manufacturing and processing equipment, and in particular relates to a speaker cover surface treatment equipment. Background Technology

[0002] In the speaker manufacturing process, the speaker cover, as an exterior component of the speaker, directly affects the overall quality and user experience due to its surface smoothness and aesthetics. Therefore, after molding, the speaker cover usually needs to undergo surface polishing to remove burrs, scratches, and other defects.

[0003] Currently, traditional speaker cabinet polishing operations mostly use single-head polishers. These polishers are typically driven by a motor to rotate the polishing head, and polishing is performed manually by holding the speaker cabinet or moving the polishing head while the cabinet is stationary. However, since a single polishing head can only polish one surface of the speaker cabinet at a time, for speaker cabinets with multiple surfaces to be polished, it is necessary to change the polishing position or adjust the workpiece posture multiple times, resulting in a lengthy polishing process and low efficiency.

[0045] The working process of this utility model is as follows:

[0046] The operator places the speaker cover workpiece to be polished on the first positioning roller 85 and the second positioning roller 95 of the clamping mechanism, so that the surface of the workpiece to be polished faces the corresponding polishing mechanism.

[0047] The operator starts the equipment through the operation panel of the control box 2. The control box 2 controls the action of the clamping mechanism: the piston rods of the first clamping cylinder 81 and the second clamping cylinder 91 extend, pushing the first clamping frame 82 and the second clamping frame 92 to descend, so that the first clamping roller 83 and the second clamping roller 93 press on the upper surface of the workpiece respectively, and cooperate with the first positioning roller 85 and the second positioning roller 95 below to stably clamp the workpiece.

[0048] After clamping is completed, the electrical control box 2 controls the operation of each grinding mechanism: the piston rods of the upper grinding cylinder 41, lower grinding cylinder 51, left grinding cylinder 61 and right grinding cylinder 71 extend respectively, driving the upper grinding head 44, lower grinding head 54, left grinding head 64 and right grinding head 74 to approach the workpiece until they contact the corresponding surface of the workpiece and reach the preset pressure.

[0049] Subsequently, the electrical control box 2 controls the start of the upper grinding motor 43, lower grinding motor 53, left grinding motor 63 and right grinding motor, driving each grinding head to rotate and simultaneously perform grinding operations on the four surfaces of the workpiece: upper, lower, left and right.

[0050] After the grinding operation reaches the preset time, the electrical control box 2 controls each grinding motor to stop working, and the piston rod of each grinding cylinder retracts, driving the grinding head away from the workpiece.

[0051] Finally, the control box 2 controls the piston rod of the clamping cylinder of the clamping mechanism to retract, the clamping roller rises, and the workpiece is released. The operator then removes the polished workpiece, completing one polishing cycle.

[0052] The speaker cover surface treatment equipment provided in this application, by setting up an upper grinding mechanism 4, a lower grinding mechanism 5, a left grinding mechanism 6 and a right grinding mechanism 7, can simultaneously grind the upper, lower, left and right surfaces of the speaker cover, without having to change the grinding position or adjust the workpiece posture multiple times, thus shortening the grinding operation time and effectively improving the grinding efficiency.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
