DETAILED DESCRIPTION
[0031] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0032] See also Figure 1This mobile phone back cover grinding and polishing equipment has a drive motor 2 installed on the lower support plate of the frame 1. This drive motor 2 can drive the angular reducer 3 to work after being energized. A circular grinding disc 4 is installed on the output shaft of the angular reducer 3. The grinding disc 4 passes through the through hole in the middle of the horizontal plate 5, and then a plurality of limit seats 6 (4 in the figure) are installed on the outer circle of the through hole. The limit seat 6 extends to the top of the grinding disc 4, which can limit the position of the placement seat 7 to prevent the placement seat 7 from being thrown out of the top of the grinding disc 4 as the grinding disc 4 moves. The bottom of the placement seat 7 is a concave groove structure, and the back cover of the mobile phone to be polished can be stuck in the groove and then buckled on the grinding disc 4. The grinding operation can be performed when the grinding disc 4 rotates.
[0033] See also Figure 2 The limit seat 6 is installed on the horizontal plate 5 through the column 8. The limit plate 9 on the side wall of the column 8 is arc-shaped, which can fit the cylindrical placement seat 7, and rollers 10 are installed on both ends of the arc of the limit plate 9 through shaft movement. The roller 10 can fit on the side wall of the placement seat 7. When the grinding disc 4 rotates, the placement seat 7 may rotate by itself. After being supported by the roller 10, it can adapt to the rotation, avoiding direct hard contact, which causes the placement seat 7 to slip.
[0034] In order to facilitate the adjustment of the height of the limiting plate 9, a waist-shaped hole can be opened on the column 8, and the limiting plate 9 can be installed by bolt fixing. This structure makes the height of the limiting plate 9 adjustable.
[0035] See also Figure 1 There is an upwardly extending connecting plate 11 on the rear side of the frame 1, and an upper bracket 12 parallel to the frame 1 is provided at the upper end of the connecting plate 11. The number of pressing mechanisms installed on the upper bracket 12 is the same as the number of the placement seats 7. One pressing mechanism is used in conjunction with one placement seat 7. The pressing mechanism provides downward pressure for the placement seat 7 to ensure that the placement seat 7 is always in contact with the grinding disc 4.
[0036] See also Figure 3 The telescopic cylinder 13 on the downward pressing mechanism can drive the pressure plate 14 to move downward. There is a brushless motor 19 above the pressure plate 14. The brushless motor 19 can drive the pressure plate 14 to rotate. During the grinding operation, the back cover of the mobile phone is not only ground in a straight line with the grinding disc, but also rotates circumferentially under the drive of the pressure plate 14. The double rotation coordination improves the grinding efficiency.
[0037] A locking cylinder 16 is movably mounted on one side of the telescopic cylinder 13 on the upper bracket 12 through a cylinder mounting bracket 15. At the same time, a hook 17 is movably mounted on the lower end of the cylinder mounting bracket 15 through an axis. The telescopic rod of the locking cylinder 16 drives the hook 17 to rotate along the axis. An annular hook ring 18 is fixed to the telescopic rod of the telescopic cylinder 13. The hook 17 can be hooked on the lower edge of the hook ring 18 under the drive of the locking cylinder 16, thereby completing the positioning of the lower end structure of the telescopic cylinder 13 and preventing the structure at the lower end of the telescopic cylinder 13 from falling.
[0038] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.
[0039] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.
[0040] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
