Description

Technical Field

[0001] The utility model relates to the technical field of coating hangers, in particular to a hanger with an adjustment structure. Background Art

[0002] When producing the back shell of a mobile phone, it usually needs to go through the coating process. During the coating operation of the back shell of the mobile phone, a special hanger is needed to position the back shell of the mobile phone, so as to facilitate the coating operation.

[0003] According to a publicly disclosed hanger for optical coating of mobile phone rear cover (publication number: CN212741517U), in the above application, two sets of first clamping plates that can move toward each other under the control of a servo motor are arranged on the bottom plate, so that the rear shells of mobile phones of different sizes can be clamped and positioned.

[0004] However, in actual use of the above-mentioned equipment, the sizes and thicknesses of mobile phone back shells are different. When the mobile phone back shell is placed on the base and the clamps at both ends are adjusted to be close to each other, the pressure of the clamps will cause the mobile phone back shell to easily deviate in the vertical direction, which will cause the mobile phone back shell to not be parallel to the base in the end, causing adverse effects on subsequent coating operations. In view of this, we propose a hanger with an adjustment structure. Utility Model Content

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a hanger with an adjustment structure, including a base 1, a servo motor 2 is fixedly installed on the outer wall of the end of the base 1, an adjusting screw 3 is fixedly connected to the output end of the servo motor 2, the outer wall of the adjusting screw 3 is threadedly connected to a T-shaped threaded slide 4, and a side wall of the T-shaped threaded slide 4 is provided with a clamping block assembly, which includes a lower clamping block 5, a telescopic rod 6, an upper clamping block 7, an adjusting bolt 8, a contact pattern 9, a fixing rod 10, a contact roller 11 and a volute spring 12.

[0025] In one embodiment of the utility model, a lower clamping block 5 is fixedly installed on the side wall of the T-shaped threaded slide 4, the top of the lower clamping block 5 is fixedly connected to the bottom end of the telescopic rod 6, the top of the telescopic rod 6 is fixedly connected to the upper clamping block 7, the inner wall of the upper clamping block 7 is threadedly connected to the adjusting bolt 8, the side wall of the lower clamping block 5 is fixedly installed with a contact pattern 9, a rotating groove is opened on the inner wall of the end of the lower clamping block 5, a fixing rod 10 is rotatably installed on the inner wall of the rotating groove, a contact roller 11 passes through the fixing rod 10, and the contact roller 11 is fixedly connected to the fixing rod 10, and a volute spring 12 is sleeved on the arc-shaped outer wall of the fixing rod 10.

[0026] Furthermore, a rectangular groove with a width matching that of the bottom of the T-shaped threaded slide 4 is formed on the inner wall of the base 1, and the bottom of the T-shaped threaded slide 4 is arranged in the rectangular groove to guide and restrict the movement of the T-shaped threaded slide 4. Specifically, when the servo motor 2 is started, the T-shaped threaded slide 4 is moved horizontally along the inner wall of the rectangular groove in coordination with the rotation of the adjusting screw rod 3. In addition, there are two groups of T-shaped threaded slides 4, and the inner walls of the two groups of T-shaped threaded slides 4 are provided with threaded holes matching the adjusting screw rod 3, and the thread directions of the threaded holes in the two groups of T-shaped threaded slides 4 are opposite, so that when the adjusting screw rod 3 rotates, the two groups of T-shaped threaded slides 4 will keep moving toward or away from each other. Specifically, the clamping block assembly is arranged on the outer wall of one side of the two groups of T-shaped threaded slides 4 close to each other, and two groups of clamping block assemblies are arranged on the side of each group of T-shaped threaded slides 4, and the two groups of clamping block assemblies are mirror-imaged on the left and right sides of the central axis of the T-shaped threaded slide 4.

[0027] In addition, the upper clamp block 7 and the lower clamp block 5 are configured in the same manner, and the upper clamp block 7 and the lower clamp block 5 are both configured to be L-shaped. Specifically, the adjusting bolt 8 is disposed at a right angle between the upper clamp block 7 and the lower clamp block 5, and the inner wall of the upper clamp block 7 is provided with a threaded groove that can match the adjusting bolt 8. At the same time, there are two groups of telescopic rods 6, and the two groups of telescopic rods 6 are respectively disposed at the ends of the upper clamp block 7 and the lower clamp block 5. Further, when the adjusting bolt 8 is rotated, the upper clamp block 7 is restricted by the two groups of telescopic rods 6, so that the upper clamp block 7 will move closer to or away from the lower clamp block 5 in the vertical direction, thereby changing the clamping range of the upper clamp block 7 and the lower clamp block 5 to adapt to the positioning requirements of the back shells of mobile phones of different thicknesses. At the same time, the contact pattern 9 is disposed on the outer surface of the upper clamp block 7 and the lower clamp block 5 on the side close to the center of the base 1. The contact lines 9 are arranged in a V-shape, and the number of contact lines 9 is arranged in several groups, and the several groups of contact lines 9 are evenly distributed in a linear array on the outer surface of the upper clamp block 7 and the lower clamp block 5 close to the center of the base 1. Specifically, the V-shaped notches of two adjacent contact lines 9 are arranged oppositely, thereby improving the positioning and anti-slip effect of the upper clamp block 7 and the lower clamp block 5 on the back shell of the mobile phone, and ensuring the stability of the back shell of the mobile phone during coating. In addition, the rotating groove is opened at one end where the two groups of upper clamp blocks 7 are close to each other, so that when the two groups of upper clamp blocks 7 and the lower clamp block 5 on the base 1 are close to each other, the back shell of the mobile phone will not be stuck or stuck when it contacts the upper clamp block 7 and the lower clamp block 5, so that the combination of the upper clamp block 7 and the lower clamp block 5 can better achieve the positioning and clamping effect on the back shell of the mobile phone.

[0028] Specifically, the two ends of the spiral spring 12 are respectively fixedly connected to the inner wall of the rotating groove and the arc-shaped outer wall of the fixed rod 10, so that when the fixed rod 10 and the contact roller 11 rotate, the elastic force of the spiral spring 12 makes the fixed rod 10 and the contact roller 11 always have a movement tendency of rotating in the opposite direction to achieve reset, thereby facilitating the upper clamping block 7 and the lower clamping block 5 to position and clamp the back shell of the mobile phone, while preventing the edge of the back shell of the mobile phone from getting stuck with the upper clamping block 7 and the lower clamping block 5, thereby ensuring the positioning and clamping effect of the device on the back shell of the mobile phone.

[0029] In an embodiment of the utility model, a rotating cavity is provided on the inner wall of the contact roller 11, one end of a torsion bar 13 is fixedly connected to the inner wall of the rotating cavity, the other end of the torsion bar 13 is fixedly connected to a swing plate 14, a contact ball 15 is fixedly installed on one end of the swing plate 14 away from the torsion bar 13, and a wavy pattern 16 is provided on the spherical surface of the contact ball 15.

[0030] Specifically, there are multiple groups of rotating cavities, and the multiple groups of rotating cavities are arranged in a spiral array on the arc-shaped outer wall of the contact roller 11. At the same time, the width of the swing plate 14 is adapted to the width of the rotating cavity, so that the swing plate 14 can rotate on the inner surface of the rotating cavity with the torsion bar 13 as the rotation center. Specifically, the contact ball 15 is made of rubber material, which ensures the contact effect between the contact ball 15 and the back shell of the mobile phone while avoiding damage to the surface of the back shell of the mobile phone, thereby affecting the processing quality of the back shell of the mobile phone.

[0031] In the utility model, when in use, the back shell of the mobile phone is placed on the base 1, and the servo motor 2 is started to drive the adjusting screw 3 to rotate. At this time, the two groups of T-shaped threaded slides 4 are close to each other, so as to clamp the back shell of the mobile phone between the two groups of T-shaped threaded slides 4. In this process, by providing a clamping block assembly, the user can rotate the adjusting bolt 8 to make the upper clamping block 7 move upward relative to the lower clamping block 5 until the height of the upper clamping block 7 slightly exceeds the height of the back shell of the mobile phone. After that, when the back shell of the mobile phone and the upper clamping block 7 and the lower clamping block 5 are close to each other, the back shell of the mobile phone can be centered through the setting of the contact roller 11 to avoid its position on the base 1 from being offset, affecting the subsequent coating processing work, and cooperate with the upper clamping block 7 and the lower clamping block 5. The several groups of contact lines 9 arranged in a V-shape on the sides of the lower clamping block 5 are improved to improve the positioning and anti-slip effect of the upper clamping block 7 and the lower clamping block 5 on the back shell of the mobile phone, thereby ensuring the stability of the back shell of the mobile phone during coating.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
