[0002] After the antenna is produced, it is in a flat state, and is bent and fitted according to the internal shape of the mobile phone case. When the antenna is assembled on the mobile phone case, it has a drop surface, bends, and rotation angles, such as Figure 1 The figure shows the structure of the finished antenna. When assembling the antenna into the interior of a mobile phone case, it is necessary to match and fit it according to the internal structure. Therefore, during assembly, the antenna needs to be shaped and fitted into the mobile phone case. Combined with the structure of the finished antenna, it is considered to use a tooling that can grab the antenna from the antenna bending mechanism and shape and fit it, so as to improve the efficiency of fitting the antenna.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] See also Figure 2-Figure 9 As shown, in the embodiment of the utility model, a FPC antenna tail angle shaping mechanism is proposed, which belongs to a process in a mobile phone assembly production line, and is to Figure 1After the antenna shown is bent by the plane bending mechanism, it needs to be adapted to the internal structure of the mobile phone case for shaping and positioning and attachment. Therefore, the shaping needs to be completed during the process of grabbing the antenna, and the antenna can be reliably positioned in the mobile phone case by adjusting the position. Specifically, it includes a negative pressure adsorption block 1 and a telescopic mechanism 2 installed on the negative pressure adsorption block 1, the telescopic mechanism 2 is equipped with a guide block 3 that moves along a first direction, and the guide block 3 is equipped with a shaping and positioning block 4 that moves along a second direction through a sliding component 7, the first direction is perpendicular to the second direction, and the telescopic mechanism 2 moves the guide block 3 and the shaping and positioning block 4 relative to the negative pressure adsorption block 1 in the first direction, and the shaping and positioning block 4 can move relative to the negative pressure adsorption block 1 in the second direction.

[0031] Specifically, a first shaping surface 100 is provided on the negative pressure adsorption block 1, and a second shaping surface 40 cooperating with the first shaping surface 100 is provided on the shaping positioning block 4. When the shaping positioning block 4 approaches the negative pressure adsorption block 1, the first shaping surface 100 cooperates with the second shaping surface 40 to complete the shaping process of the antenna. When attached to the mobile phone case, the entire mechanism is moved to the mobile phone case positioning fixture, and the shaping positioning block 4 is stopped during the downward movement, and the negative pressure adsorption block 1 continues to move down with the shaped antenna into the mobile phone case to achieve attachment, thereby completing the process of grabbing the antenna, shaping and attaching.

[0032] It also includes a first limiting mechanism 5 and a second limiting mechanism 6. The first limiting mechanism 5 is used to limit the moving distance of the guide block 3 relative to the negative pressure adsorption block 1, and the second limiting mechanism 6 is used to limit the moving distance of the shaping positioning block 4 relative to the guide block 3. Since the speed is fast during resetting, the first limiting mechanism 5 and the second limiting mechanism 6 can achieve short-distance limiting during the rapid resetting process, so that the subsequent relative moving distance can be within a fixed range, meeting the speed of rapid continuous action.

[0033] Among them, the first limiting mechanism 5 includes a first screw rod 51 threadedly connected to the guide block 3, and a first adjusting nut 52 is provided on the first screw rod 51. A limiting block 53 is provided at one end of the first screw rod 51 close to the negative pressure adsorption block 1. The length of the first screw rod 51 extending on the guide block 3 is adjusted by the first adjusting nut 52, so that the moving position of the guide block 3 relative to the negative pressure adsorption block 1 can be limited in advance, and the limiting block 53 can achieve a certain buffer.

[0034] The second limiting mechanism 6 includes a sliding rod 61 passing through the guide block 3 and a screw hole column 62 fixed on the shaping positioning block 4. The lower end of the sliding rod 61 is threadedly connected to the screw hole column 62. The upper end of the sliding rod 61 passing through the guide block 3 is provided with a limiting cap 63. The sliding rod 61 is provided with a second adjusting nut 64. The moving distance between the shaping positioning block 4 and the guide block 3 is achieved by rotating the sliding rod 61 relative to the screw hole column 62, and the adjusted moving distance is locked by the second adjusting nut 64, thereby enabling the moving distance in the second direction to be adjusted in advance.

[0035] Specifically, the sliding connection of the shaping positioning block 4 relative to the guide block 3 is connected through a sliding assembly 7, and the sliding assembly 7 includes a sliding sleeve 71 arranged on the guide block 3 and a second screw 72 passing through the sliding sleeve 71, the lower end of the second screw 72 is fixed on the shaping positioning block 4, and the second screw 72 is sleeved with a reset spring 73 located between the sliding sleeve 71 and the shaping positioning block 4. During relative movement, the sliding sleeve 71 can guide the sliding of the second screw 72 in the second direction, and the reset spring 73 can quickly reset the shaping positioning block 4, and under the action of the second limiting mechanism 6, the moving distance is limited and quickly reset to the initial state.

[0036] Specifically, the telescopic mechanism 2 includes a cylinder fixed on the negative pressure adsorption block 1, and a telescopic rod of the cylinder is fixed on the guide block 3. The relative position of the guide block 3 is moved and controlled by the cylinder. At the same time, the telescopic mechanism 2 can also use technologies such as linear screws in addition to the cylinder.

[0037] Specifically, an air chamber 101 is provided on the negative pressure adsorption block 1, and a plurality of first adsorption holes 102 are provided in the air chamber 101 and penetrate to the end face of the negative pressure adsorption block 1 on which the antenna is attached. A sealing seat is installed on the air chamber 101, and an air inlet hole 103 is provided on the sealing seat. The air path in the assembly line is connected through the air inlet hole 103, and negative pressure adsorption is generated on the antenna through the plurality of first adsorption holes 102. The negative pressure adsorption positioning of the antenna can be maintained during the shaping and attachment process, and the first adsorption holes 102 release the negative pressure state to realize the detachment of the antenna from the negative pressure adsorption block 1.

[0038] After the antenna is bent at the tail corner, it may be difficult to separate from the first shaping surface 100, and the bending part needs to be reliably adsorbed during shaping. Therefore, a second adsorption hole 104 penetrating the bending part of the first shaping surface 100 is also provided in the negative pressure adsorption block 1. A trachea connector 8 is installed on the negative pressure adsorption block 1. The second adsorption hole 104 connects the air chamber 101 with the trachea connector 8. During negative pressure adsorption, the second adsorption hole 104 is connected with the air chamber 101 to generate adsorption negative pressure, and when separation is required, air is blown inward through the trachea connector 8 to accelerate the separation of the bent tail corner from the first shaping surface 100. Of course, when the stability of negative pressure adsorption is not high, the trachea connector 8 can also participate in the negative pressure adsorption process.

[0039] At the same time, a limiting portion 41 extending toward one side of the negative pressure adsorption block 1 is provided on the shaping positioning block 4, and the limiting portion 41 can further achieve reliable limiting at the maximum range of relative movement.
