After the antenna is bent by the antenna bending mechanism, it is necessary to grasp the antenna to the corresponding position of the mobile phone case and then press the antenna with a fixture that matches the internal shape of the mobile phone case. However, the circumferentially bent portion may be pulled and damaged during the pressing process. Therefore, it is necessary to solve the problem of circumferentially bending the antenna to adapt to the shape of the mobile phone case during the process of grasping and fitting the antenna to the mobile phone case.

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-Figure 7 As shown, in the embodiment of the utility model, an antenna automatic bonding jig is proposed, which is used in the mobile phone assembly line, and cooperates with the manipulator to grasp the antenna that has been longitudinally bent and realize the matching R angle of the mobile phone shell to be circumferentially bent and bonded into the mobile phone shell, completing the antenna grasping, bending and bonding process. Specifically, it includes a positioning jig 1 for positioning the mobile phone shell and a grasping jig 2 for grasping the antenna and bonding it to the mobile phone shell. The positioning jig 1 realizes the limited placement of the mobile phone shell, and the grasping jig 2 completes the grasping and bending of the antenna.

[0029] Specifically, the gripping fixture 2 includes a vacuum adsorption positioning block 21, and the vacuum adsorption positioning block 21 has a negative pressure air chamber 22. The vacuum adsorption block is provided with an adsorption surface 23 located on the bottom and a positioning surface 24 located on the side. The adsorption surface 23 and the positioning surface 24 are both provided with adsorption holes 25 connected to the negative pressure air chamber 22, which are connected to an external negative pressure air source through the negative pressure air chamber 22, and the adsorption holes 25 are connected to the negative pressure air chamber 22. Therefore, after negative pressure adsorption of the antenna is achieved through multiple adsorption holes 25 according to the structural arrangement of the antenna, preliminary adsorption positioning is formed on the adsorption surface 23 and the positioning surface 24. At the same time, two telescopic cylinders 26 are installed at intervals on the vacuum adsorption positioning block 21, and support blocks 27 are installed on the telescopic rods of the two telescopic cylinders 26. Two slidable sliding rods 28 are installed at intervals on the support block 27, and a pressing block 29 is installed on the two sliding rods 28. The pressing block 29 is provided with a forming concave surface 290. After the antenna is captured and adsorbed and positioned, in the process of moving to the positioning fixture 1, the telescopic cylinder 26 pulls the pressing block 29 to move toward the vacuum adsorption block, so that the forming concave surface 290 on the pressing block 29 cooperates with the positioning surface 24 on the vacuum adsorption positioning block 21 to bend and form the antenna, thereby completing the bending and forming of the antenna. The antenna bending completed here is to match the R angle at the corner of the mobile phone case, so the bending radius is the same as the corner radius of the mobile phone case.

[0030] The vacuum adsorption positioning block 21 includes an adsorption base block 2101, the negative pressure air chamber 22 and the adsorption hole 25 are arranged on the adsorption base block 2101, and the adsorption base block 2101 is provided with a sealing plate 2102 for sealing the negative pressure air chamber 22, and the sealing plate 2102 is provided with a mounting seat 2103 at intervals, and the mounting seat 2103 is used to install the telescopic cylinder 26. At the same time, the sealing plate 2102 is provided with an air hole 2104 for connecting the air pipe joint, and the external negative pressure suction makes the negative pressure air chamber 22 have a negative pressure, so that the negative pressure adsorption of the antenna is realized through the adsorption hole 25. The sealing plate 2102 effectively seals the negative pressure air chamber 22, and the mounting seat 2103 integrated on the sealing plate 2102 realizes the installation of the telescopic cylinder 26, so that the telescopic cylinder 26 is integrated and installed on the vacuum adsorption positioning block 21.

[0031] After the bending is completed, the antenna is moved to the position of the mobile phone case and moved downward to fit the antenna into the mobile phone case. The positioning fixture 1 forms a stop for the pressing block 29. Under the action of the sliding rod 28, the pressing block 29 moves upward relative to the vacuum adsorption positioning block 21 to fully expose the antenna until it fits into the mobile phone case, completing the antenna fitting. After the antenna is fitted, the entire height is raised and the pressing block 29 automatically moves downward to reset under the action of gravity.

[0032] Specifically, the positioning surface 24 and the molding concave surface 290 both include a straight surface and arc surfaces at both ends of the straight surface. The straight surface is used to achieve compression and positioning of the portion of the antenna that is not bent, while the arc surface is used to perform circumferential bending on the two ends of the antenna. Specifically, the radius R of the arc surface is the same as the radius R of the portion of the mobile phone case where the antenna is attached, so that matching bending can be achieved after molding.

[0033] At the same time, in order to avoid excessive squeezing of the antenna, or to adjust the distance between the positioning surface 24 and the molded concave surface 290 according to the thickness of the antenna, limiting bolts 210 are installed at intervals on the support block 27, and a locking nut 211 is provided on the limiting bolt 210. After the length of the limiting bolt 210 is adjusted by rotating relative to the support block 27, the limiting bolt 210 is locked by the locking nut 211, and the relative movement distance is limited by the length of the limiting bolt 210 extending out of the support block 27. Specifically, a stop block 212 corresponding to the limiting bolt 210 is provided on the vacuum adsorption positioning block 21, and the stop block 212 forms a stopping fit with the limiting bolt 210. When the antenna is bent, the limiting bolt 210 is pressed against the stop block 212.

[0034] In order to ensure good sliding properties of the sliding rod 28 relative to the support block 27, a sliding sleeve 213 is installed on the support block 27, and the sliding rod 28 is slidably matched with the sliding sleeve 213. The sliding friction is reduced by the cooperation between the sliding sleeve 213 and the sliding rod 28. The sliding sleeve 213 can be a copper sleeve or a graphene sleeve.

[0035] The positioning fixture 1 is used to limit and position the mobile phone case, and can block the pressing block 29 so that the vacuum adsorption positioning block 21 can continue to move toward the mobile phone case with the antenna. Specifically, the positioning fixture 1 includes a positioning seat 11 and a positioning protrusion 12 provided on the positioning seat 11. The positioning seat 11 is also provided with limiting blocks 13 located at both ends and both sides of the positioning protrusion 12. A positioning groove 14 for placing the mobile phone case is formed between the positioning protrusion 12 and the limiting blocks 13. The positioning protrusion 12 on the positioning seat 11 is used to form a matching positioning of the edge of the inner frame of the mobile phone case, and the limiting blocks 13 located at the four corner positions are used to limit the mobile phone case. The four corner positions of the mobile phone case are reliably positioned by the positioning groove 14; the two limiting blocks 13 located on the side of the mobile phone case that fits the antenna are used to form a stop limit during the downward movement of the pressing block 29.

[0036] Among them, the limit block 13 is in an "L"-shaped structure, which just matches the corner position of the mobile phone case to form a limit, and a guide surface 16 inclined toward one side of the positioning protrusion 12 is provided on the limit block 13, which is convenient for guiding and automatically achieving the limited placement on all sides when the mobile phone case is placed on the positioning protrusion 12.

[0037] At the same time, a placement groove 15 for placing the raised structure on the mobile phone case is provided on the positioning protrusion 12. Since the current mobile phone case has a part protruding outward, such as a lens part, it is necessary to provide a placement groove 15 at the corresponding raised structure part to avoid it, so as to ensure that the mobile phone case is flat after being placed on the positioning protrusion 12, thereby ensuring the yield of the antenna fitting.
