[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 A glasses frame welding fixture in this embodiment includes a support frame 1, a horizontal rotating motor 2 is fixed to the left side of the support frame 1, a rotating sleeve 3 is fixed to the output end of the horizontal rotating motor 2 and is rotatably connected to the right inner wall of the support frame 1 through a bearing, a vertical rotating motor 4 is fixed to the bottom surface of the rotating sleeve 3, and a fixing frame 5 is fixed to the output shaft of the vertical rotating motor 4, and two supporting platforms 6 for placing the glasses frame are fixed on the fixing frame 5, a clamping mechanism 7 for pressing the side surface of the glasses frame is provided on the fixing frame 5, and a pressing mechanism 8 for pressing the top surface of the glasses frame is also provided on the fixing frame 5.

[0024] The eyeglass frame is placed on the support platform 6, and the edge of the support platform 6 is formed inwardly into a groove such as Figure 3 As shown, the glasses frame is placed on the support platform 6 so that the glasses frame can be placed more stably.

[0025] The side of the eyeglass frame is tightened by the clamping mechanism 7, such as Figure 4-5 As shown, the clamping mechanism 7 includes a clamping structure 1 and a clamping structure 2. The clamping structure 1 is composed of four groups, and respectively limits the corners of the opposite sides of the two groups of eyeglass frames. The clamping structure 2 is a group, and together limits the corners of the opposite sides of the two groups of eyeglass frames, so that the eyeglass frames can be firmly clamped on the support platform 6.

[0026] The clamping structure 1 includes a fixed platform 701 fixed on the fixed frame 5, and two T-shaped limit rods 702 are movably connected to the fixed platform 701. The ends of the two T-shaped limit rods 702 are commonly fixed with a movable block 703. The outer sides of the two T-shaped limit rods 702 are both sleeved with buffer springs 704. The buffer springs 704 are arranged between the fixed platform 701 and the movable block 703. An L-shaped pad 705 is fixed on one side of the movable block 703. The movable block 703 can drive the T-shaped limit rod 702 to slide in the fixed platform 701. The tension of the buffer spring 704 can enable the movable block 703 to drive the L-shaped pad 705 to press the glasses frame onto the support platform 6.

[0027] One end of the T-shaped limiting rod 702 away from the movable block 703 is restricted on the fixed platform 701 , so as to prevent the T-shaped limiting rod 702 from being separated from the fixed platform 701 .

[0028] The second clamping structure includes a mounting platform 706 fixed on the fixing frame 5, and two T-shaped fixing rods 707 are fixed inside the mounting platform 706. The outer sides of the two T-shaped fixing rods 707 are slidably sleeved with limit blocks 708. The outer sides of the T-shaped fixing rods 707 are sleeved with clamping springs 709 located between the limit blocks 708 and the mounting platform 706. Two positioning rods 710 are provided on the limit blocks 708. The limit blocks 708 can slide freely on the outer sides of the two T-shaped fixing rods 707. The tension of the clamping springs 709 causes the two positioning rods 710 on the limit blocks 708 to press the edges of the two eyeglass frames onto the supporting platform 6 respectively.

[0029] The end of the T-shaped fixing rod 707 away from the mounting platform 706 can limit the limiting block 708 to prevent the limiting block 708 from sliding off the T-shaped fixing rod 707 .

[0030] After the side of the glasses frame is clamped on the support platform 6 by the clamping mechanism 8, the top edge of the glasses frame can also be clamped on the support platform 6 by the clamping mechanism 8. Figure 6 The pressing mechanism 8 includes an angular cylinder 801 fixed on the fixing frame 5, and a pressing member 803 is fixed to the output end of the angular cylinder 801 through a connecting member 802. In the initial state, the pressing member 803 is located on the inner side of the groove edge of the supporting platform 6, and will not affect the placement of the glasses frame on the supporting platform 6. When the pressing operation is required, the angular cylinder 801 drives the connecting member 802 to rotate, driving the pressing member 803 to rotate to above the top edge of a corner of the glasses frame, and then drives the pressing member 803 to move vertically downward through the connecting member 802, and the glasses frame is pressed onto the supporting platform 6 by the pressing member 803.

[0031] By adopting the above-mentioned glasses frame welding fixture, the glasses frame can be firmly clamped, thereby improving the accuracy of glasses frame welding. The specific clamping method is as follows:

[0032] The eyeglass frame is placed in the groove on the support platform 6. The tension of the buffer spring 704 allows the L-shaped pad 705 to press the side of the eyeglass frame onto the support platform 6. The tension of the compression spring 709 allows the two positioning rods 710 on the limit block 708 to press the edges of the other sides of the two eyeglass frames onto the support platform 6 respectively. Then, the connecting piece 802 is driven to rotate by the angle cylinder 801, driving the pressing piece 803 to rotate to above the top edge of one corner of the eyeglass frame, and the pressing piece 803 is driven to move vertically downward by the connecting piece 802, and the eyeglass frame is pressed onto the support platform 6 by the pressing piece 803, so that the eyeglass frame is firmly clamped.

[0033] After clamping, the horizontal rotary motor 2 can drive the eyeglass frame to flexibly adjust the angle in the vertical direction, and the vertical rotary motor 4 can drive the eyeglass frame to flexibly adjust the angle in the horizontal direction, thereby improving the flexibility of the eyeglass frame during welding.

[0034] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
