DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-Figure 6 As shown, in the embodiment of the utility model, a planar FPC antenna shaping suction head is proposed, which is used in a mobile phone assembly production line, and is used to grab and shape the planar FPC antenna and then attach and fix it in a mobile phone shell. It specifically includes a negative pressure adsorption block 1 and a sliding seat 3 installed on the negative pressure adsorption block 1, and a sliding block 2 is slidably installed on the sliding seat 3. A cylinder 4 for pushing or pulling the sliding block 2 to slide is installed on the negative pressure adsorption block 1, wherein a negative pressure air chamber is provided on the negative pressure adsorption block 1, and a first adsorption portion 101 for adsorbing and positioning a first part of the FPC antenna is provided on the negative pressure adsorption block 1, and at least one first adsorption hole 102 connected to the negative pressure air chamber is opened on the first adsorption portion 101, and at the same time, a second adsorption portion 21 for adsorbing and positioning a second part of the FPC antenna is provided on the sliding block 2. The second adsorption part 21 is provided with at least one second adsorption hole 22 connected to the negative pressure air chamber; after the negative pressure air chamber is connected to the negative pressure air source, the first adsorption hole 102 in the first adsorption part 101 generates negative pressure to adsorb and position the first part of the FPC antenna, and at the same time, the second adsorption hole 22 in the second adsorption part 21 generates negative pressure to adsorb and position the second part of the FPC antenna, and then the sliding block 2 is pushed to move by the cylinder 4, so that the second adsorption part 21 grabs the second part of the FPC antenna and moves toward the first part. Since the first part is also positioned, the part between the first part and the second part is arched upward, thereby completing the shaping of the FPC antenna to adapt to the corresponding fixed point in the mobile phone case, and allowing the arched part to just pass over the protruding structure in the mobile phone case to avoid interference, thereby improving the antenna attachment efficiency.

[0028] Among them, the negative pressure is actually the middle part that connects various adsorption holes internally and forms negative pressure. Specifically, a ventilation groove 108 and a sealing cover 109 that seals the ventilation groove 108 are provided on the negative pressure adsorption block 1. The sealing cover 109 and the ventilation groove 108 are enclosed to form the negative pressure air chamber. The sealing cover 109 is provided with a mounting hole 110, and the mounting hole 110 is used to install the air source connector. The air source is connected through the air source connector to realize negative pressure extraction or positive pressure blowing, and the sealing cover 109 is used to seal the ventilation groove 108, and the sealing cover 109 is detachable to facilitate the installation of the air source connector.

[0029] In order to further improve the reliable grasping and limiting of the first part of the FPC antenna by the first adsorption portion 101, first elastic needles 103 are provided in the first adsorption holes 102 at both ends close to the first part of the FPC antenna, and first suction cups 104 are installed in the other first adsorption holes 102. By adding the first suction cups 104, the FPC antenna can be grasped more stably, and the first elastic needle 103 can be inserted into the hole at the corresponding position of the FPC antenna to further achieve limiting, avoid the risk of detachment, and improve the bearing capacity during the antenna shaping process.

[0030] Similarly, a second elastic needle 23 is provided in one of the second adsorption holes 22, and a second suction cup 24 is installed in the other second adsorption hole 22. The second suction cup 24 enhances the negative pressure adsorption effect at the second adsorption hole 22, and the second elastic needle 23 is inserted into the hole corresponding to the second part of the FPC antenna to ensure the adsorption positioning state during movement to avoid detachment.

[0031] Therefore, after the first and second parts of the FPC antenna are further reliably adsorbed and fixed, the risk of slipping of the first and second parts can be avoided during the shaping process, ensuring that the position of the arched part between the first and second parts meets the adaptability of the entire antenna after being attached to the mobile phone case, and being able to achieve consistent assembly in continuous assembly line operations to improve the yield rate.

[0032] In order to allow the first part and the second part to move along their own extension direction during the shaping process and satisfy the arch deformation of the corresponding intersection, the sliding direction of the sliding block 2 and the length direction of the first adsorption portion 101 are arranged at an angle. The angle here is the angle between the first part and the second part of the FPC antenna. If any change occurs, the corresponding arrangement will follow the change, which is to adapt to the corresponding adsorption and fixation of the two parts of the FPC antenna.

[0033] The sliding block 2 is guided and supported by the sliding seat 3, but the sliding block 2 needs to be kept connected with the negative pressure air chamber when sliding, and the negative pressure state of the second adsorption part 21 is maintained. Specifically, a sliding groove 105 for accommodating the sliding block 2 is opened on the negative pressure adsorption block 1, and a strip hole 106 connected to the sliding groove 105 is opened at the bottom of the negative pressure air chamber. When the sliding block 2 slides, the second adsorption hole 22 remains connected with the strip hole 106, and the sliding block 2 is limited by the sliding groove 105. The strip hole 106 is opened to allow the second adsorption hole 22 to move within the range of the strip hole 106 during the sliding process of the sliding block 2 to maintain a connected state.

[0034] Meanwhile, the sliding distance of the sliding block 2 only needs to satisfy the arch height, specifically, the width of the sliding block 2 is smaller than the width of the sliding groove 105 , wherein the sliding distance of the sliding block 2 is the width of the sliding groove 105 minus the width of the sliding block 2 .

[0035] Furthermore, in order to position the second adsorption part 21 when it slides toward the first adsorption part 101, maintain the state after shaping, and have a positioning reference, a reference positioning surface 107 is provided on the first adsorption part 101, and a limiting surface 25 cooperating with the reference positioning surface 107 is provided on the second adsorption part 21. When the second adsorption part 21 slides into place toward the first adsorption part 101, the limiting surface 25 is attached to the reference positioning surface 107 to achieve positioning.
