DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Since the antenna loading is generally a large protective film with several antennas adhered to it, the peeling device 3 is mainly used to peel the antenna on the antenna loading device 2 from the protective film. The antenna loading device 2 is mainly used to load the antenna peeled by the peeling device 3. The antenna transfer device 4 is mainly used to transfer the antenna on the antenna loading device 2 to the bending device 5, wherein the antenna transfer device 4 preferably includes a fifth drive device and a suction cup installed on the fifth drive device. In addition, the fifth drive device can be a manipulator, a multi-axis robot, a cylinder, etc., so it is not limited to this. The suction cup is preferably provided with a positioning portion for positioning the antenna, so as to facilitate the accuracy of the position when the antenna transfer device 4 transfers the antenna to the bending device 5. The bending device 5 is mainly used to bend the antenna. The bonding device 6 is mainly used to bond the bent antenna to the product. The product loading device 7 is arranged on the frame 1 and located on one side of the bonding device 6, and is mainly used to load the product and transport it to the bonding device 6, wherein the product loading device 7 can be a mobile phone, tablet, Bluetooth headset, etc., which need to be bonded with an antenna.

[0032] Specifically, see Figure 1-Figure 3 , the stripping device 3 first strips the antenna and the protective film, and then the antenna feeding device 2 transfers the stripped antenna to the antenna transfer device 4, wherein the present embodiment is preferably provided with a first visual positioning device 8, which is arranged on the frame 1 and located on one side of the antenna feeding device 2, and is mainly used to detect the position of the antenna on the antenna feeding device 2, so as to facilitate the antenna transfer device 4 to absorb the antenna. The first visual positioning device 8 preferably includes a first fixed bracket 81 mounted on the frame 1 and a CCD detection device 82 mounted on the first fixed bracket 81, and the CCD detection device 82 is located directly above the antenna feeding device 2, and when the CCD detection device 82 detects the position of the antenna, it transmits a signal to the antenna transfer device 4. In addition, the present embodiment also preferably includes a second visual positioning device 9, which is arranged on the frame 1 and located on one side of the antenna transfer device 4. When the antenna transfer device 4 absorbs the antenna and moves it to the top of the second visual positioning device 9, the second visual positioning device 9 can detect the position of the antenna. If the position of the antenna is skewed, a signal can be transmitted to the antenna transfer device 4, thereby adjusting the position of the antenna, thereby improving the positioning accuracy when the antenna transfer device 4 is transferred to the bending device 5, so as to facilitate the bending device 5 to bend the antenna. The second visual positioning device 9 can be a CCD image sensor or a camera device. Next, the bending device 5 bends the antenna, and then the bonding device 6 absorbs the bent antenna on the bending device 5 and bonds the antenna to the product on the product feeding device 7.

[0033] For details, please refer to Figure 7-Figure 9The bending device 5 of this embodiment preferably includes a bottom plate 51, an antenna adsorption seat 52, a sliding plate 55, an antenna flipping and bending device 53 and an antenna pressing and bending device 54 installed on the frame 1.

The antenna flipping and bending device 53 includes a bending plate 531 and a rotating mechanism 532. Among them, the bending plate 531 is arranged on one side of the antenna adsorption seat 52, and the top of the bending plate 531 and the top of the antenna adsorption seat 52 are on the same horizontal plane. The antenna pressing and bending device 54 is arranged at the other end of the antenna adsorption seat 52, and is mainly used to fix the antenna to the antenna adsorption seat 52. Specifically, after the antenna is fixed on the antenna adsorption seat 52, the antenna pressing and bending device 54 will press down and press on the antenna, and then the rotating mechanism 532 drives the bending plate 531 to fold upward. At this time, the pressure of the antenna pressing and bending device 54 pressing the antenna is downward, and the folding force of the bending plate 531 is upward, so the antenna bending operation can be performed. In addition, a crease will be formed at the position where the antenna pressing and bending device 54 presses down on the antenna. At this time, as long as the position where the antenna pressing and bending device 54 presses down on the antenna is controlled, the position of the crease of the antenna will be easily adjusted, and the rotating mechanism 532 drives the bending plate 531 to rotate a certain number of degrees, so that the antenna can be controlled to bend into various required bending angles.

[0034] See also Figure 7-Figure 8The antenna pressing and bending device 54 of this embodiment includes a slider mounting seat 541, a first slider 542, a second slider 548, a connecting rod 549, an elastic device 58, a pressure head mounting seat 544, a pressure head fixing seat 546, a pressure head 543, a lifting device 547 and a first driving device 545. The slider mounting seat 541 is mounted on the sliding plate 55 and is provided with a first sliding groove 5411. The first slider 542 and the second slider 548 slide in the first sliding groove 5411, the connecting rod 549 is sleeved on the first slider 542 and the second slider 548 and connects the first slider 542 and the second slider 548, one end of the elastic device 58 abuts on the first slider 542, and the other end abuts on the second slider 548. The pressure head mounting seat 544 is fixed on the first slider 542. The pressure head mounting seat 544 is provided with a second sliding groove 5441 in the vertical direction, and the pressure head fixing seat 546 performs a vertical lifting movement in the second sliding groove 5441. The pressure head 543 is fixed on the pressure head fixing seat 546. The lifting device 547 can be set on the second slider 548 or the first slider 542, and is mainly used to drive the pressure head fixing seat 546 to perform lifting and lowering movements in the vertical direction. The first driving device 545 can be set on the bottom plate 51 or the sliding plate 55, and is mainly used to drive the second slider 548 to slide in the first slide groove 5411. In addition, the first driving device 545 can be a cylinder, a screw rod, a linear motor, etc. Specifically, the first driving device 545 first drives the second slider 548 to move in the first slide groove 5411. Since the second slider 548 and the first slider 542 are connected by a connecting rod 549, and an elastic device 58 is abutted between the second slider 548 and the first slider 542, the second slider 548 will drive the first slider 542 to slide in the first slide groove 5411 while sliding. When the first slider 542 slides into place, the pressure head 543 will move to the position of the crease when the antenna needs to be bent. In this embodiment, a limit block 530 is preferably provided at one end of the first slide groove 5411. When the first slider 542 touches the limit block 530, the pressure head 543 moves into position. Then, the lifting device 547 drives the pressure head 543 to press down, and the pressure head 543 can press and fix the antenna. In addition, the lifting device 547 can be a driving device such as a cylinder, a screw rod, etc. to drive the pressure head 543 to rise and press down.

[0035] The bottom plate 51 of this embodiment is preferably provided with a guide rail, and the sliding plate 55 slides on the guide rail through a slider. This embodiment also preferably includes an adjusting device 59 arranged on the bottom plate 51 and used to drive the sliding plate 55 to move in the horizontal direction. Among them, the adjusting device 59 includes a push rod 591 fixedly connected to the sliding plate 55, and an adjusting knob 592 that is transmission-connected to the push rod 591 and used to control the ejection distance of the push rod 591.

The scale value on the adjusting knob 592 can control the ejection and retraction distance of the push rod 591, so as to make it easier to adjust the sliding distance of the sliding plate 55 on the bottom plate 51. The antenna flipping and bending device 53 and the antenna pressing and bending device 54 are both arranged on the sliding plate 55. In this way, the distance between the antenna flipping and bending device 53 and the antenna pressing and bending device 54 relative to the antenna adsorption seat 52 can be adjusted by adjusting the sliding plate 55, so as to facilitate the adjustment of the position of the fold on the antenna. The present embodiment also preferably includes a locking device 56 for mounting the sliding plate 55 on the bottom plate 51. After the sliding plate 55 is fine-tuned by the adjustment device 59 so that the distance between the bending plate 531 and the antenna adsorption seat 52 is appropriate, the locking device 56 mounts the sliding plate 55 on the bottom plate 51, ensuring that the sliding plate 55 does not slide, thereby ensuring that the bending plate 531 does not slide during the operation, and improving the stability and reliability of the fold in the bending operation of the present embodiment. In addition, the locking device 56 can be screw locking or buckle locking. The present embodiment is preferably screw locking, which has higher stability and is more convenient for mounting the sliding plate 55 on the bottom plate 51.

[0036] To summarize, the antenna is first placed on the antenna adsorption seat 52. The antenna adsorption seat 52 of this embodiment is preferably provided with a vacuum suction port 5211 and a positioning column 5212. The number of the positioning columns 5212 is at least two. The antenna passes through the positioning columns 5212 and is fixed on the antenna adsorption seat 52. The positioning columns 5212 are retractable, that is, they can emerge from the antenna adsorption seat 52 or retract from the antenna adsorption seat 52. This will make it easier for the machine to fix the antenna on the antenna adsorption seat 52. An elastic component may be provided at the bottom of the positioning column 5212. When the surface applies pressure to the positioning column 5212, the positioning column 5212 can be retracted from the top of the antenna adsorption seat 52. Specifically, when the manipulator sucks and places the antenna on the antenna adsorption seat 52, the positioning piece on the manipulator can be aligned with the positioning column 5212 and pressed down. At this time, when the manipulator places the antenna on the antenna adsorption seat 52, the vacuum suction port 5211 sucks the antenna, and then the manipulator leaves, and the positioning column 5212 will extend from the antenna adsorption seat 52 and into the positioning hole of the antenna, thereby improving the stability and reliability of the antenna being fixed on the antenna adsorption seat 52. In addition, the number of vacuum suction ports 5211 can be several, respectively located at various parts of the antenna, to facilitate the adsorption of various parts of the antenna and improve the reliability of the adsorption of the antenna. The vacuum suction port 5211 is connected to the air suction port of the external device, and the antenna can be sucked by controlling the air suction operation of the external device. The present embodiment is also preferably provided with an adsorption seat fixing seat 540, the adsorption seat fixing seat 540 is installed on the bottom plate 51, and the antenna adsorption seat 52 is installed on the adsorption seat fixing seat 540, so that it is convenient to fix the antenna adsorption seat 52, and different antenna adsorption seats 52 can be replaced according to different types of antennas, so as to facilitate the bending of different types of antennas in the present embodiment.

[0037] Then, the antenna pressing and bending device 54 can press the antenna on the antenna adsorption seat 52, and the part of the antenna pressed is the crease of the antenna. In addition, the pressing head 543 of this embodiment is preferably an inverted triangle structure, and a pressing portion 5431 is provided on the pressing head 543, wherein the pressing portion 5431 is the vertex in the inverted triangle structure, so that the pressing portion 5431 is a line. Since the contact area of ​​the pressing portion 5431 pressed on the antenna is small, the pressure will be greater, thereby improving the pressing strength of the pressing head 543 pressing the antenna. Then, the rotating mechanism 532 drives the bending plate 531 to rotate. At this time, the antenna on the bending plate 531 will bend with the bending of the bending plate 531, but the antenna on the antenna adsorption seat 52 will be fixed and immovable, and the antenna will be bent around the pressing portion 5431, so that the bending operation can be completed. The rotating mechanism 532 may be a motor, or a motor may be used to drive a belt, a chain, a toothed chain, etc. to rotate, thereby driving the bending plate 531 to rotate, so it is not limited thereto. The structure of this embodiment is simple and compact, and the operation is convenient. The bending angle of the antenna can be controlled by the rotating mechanism 532, and the antenna adsorption seat 52 is provided with a positioning column 5212, which is then matched with the pressure head 543 and the antenna turning and bending device 53 to complete the bending operation, so that the antenna after bending has better consistency, higher reliability, and higher production efficiency.

[0038] See also Figure 4 The laminating device 6 of this embodiment includes a third driving device 61, a vacuum suction nozzle 63 and a side bending assembly 62.

The positioning plate 724 includes a base 7241 and a positioning ejector pin 7242 disposed on the base 7241. Preferably, the material stopper 725 includes a seventh drive device and a material stopper block driven by the seventh drive device to move up and down in the vertical direction.

[0040] In summary, the working principle of the antenna and product bonding is as follows: first, the product is placed on the conveying belt 711, and the driving motor 712 drives the conveying belt 711 to rotate, thereby driving the product to move. Then, when the product moves to the material blocking device 725, the material blocking device 725 will block the product from moving forward, and then the sixth driving device 723 drives the positioning plate 724 to move up and down in the vertical direction, and the positioning ejector pin 7242 will lift the product on the conveying belt 711, wherein the position of the positioning ejector pin 7242 is preferably adapted to the four corners of the product, so that the positioning ejector pin 7242 not only lifts the product, but also provides support when the product and the antenna are attached. The sixth driving device 723 can be a cylinder, a screw, etc. Then, the vacuum suction nozzle 63 absorbs the antenna bent by the bending device 5, and two different planes will be formed on the antenna at this time, and then the fourth driving device 621 drives the bending needle 622 to move toward the antenna, and under the action of the bending needle 622, the side of the antenna will be bent into a curved surface by the bending needle 622. Among them, the bending needle 622 can be set as one and located on one side of the vacuum suction nozzle 63, or it can be set as two and located on both sides of the vacuum suction nozzle 63. In this way, the side of one end of the antenna can be bent, and the side of both ends of the antenna can be bent, so that the antenna can be bent into multiple planes, which is convenient for attaching an antenna to different planes of the product, which not only improves the attachment effect of the antenna to the product, but also improves the space utilization rate of the product. Then the third driving device 61 will lower the antenna, and the antenna will be located at the position on the product where it needs to be attached. After the vacuum suction nozzle 63 adheres the end face of the adsorbed antenna to the product, the third driving device 61 will drive the soft roller 67 to press and adhere the side of the antenna to the product. The antenna of this embodiment is bent into multiple planes before being attached to the product, which is convenient for attaching the antenna to different positions on different products.

The driving block 5473 is fixed on the second slider 548, and is mainly used to drive the pressure rod 5472 to perform lifting movement in the vertical direction. Specifically, one end of the pressure rod 5472 is transmission-connected with the pressure head fixing seat 546, and the other end is transmission-connected with the driving block 5473. When the driving block 5473 drives one end of the pressure rod 5472 to rise, the other end of the pressure rod 5472 will drop, thereby driving the pressure head fixing seat 546 to drop, and then driving the pressure head 543 to press down. Among them, a reset elastic member 520 is preferably provided between the pressure head fixing seat 546 and the pressure head mounting seat 544, and the reset elastic member 520 is mainly used to apply an upward restoring force to the pressure head fixing seat 546. That is, when one end of the pressure rod 5472 applies a descending pressure to the pressure head fixing seat 546, the reset elastic member 520 will always lift up the pressure head fixing seat 546, so that the pressure head 543 is in a suspended state, which is convenient for the pressure head 543 to return to its original position from the downward pressure state. In addition, the reset elastic member 520 can be a spring, a compression spring, a disc spring, etc., so it is not limited to this. More specifically, the top of the driving block 5473 is provided with an inclined surface 54732, wherein the two sides of the inclined surface 54732 are preferably provided with a first plane 54731 and a second plane 54733, so that the height of the pressure rod 5472 rising and falling can be controlled, thereby controlling the height of the pressure head 543 rising and the force of pressing down. In this embodiment, the height of the pressure head 543 rising and the force of pressing down are controlled by the first plane 54731 and the second plane 54733. In other embodiments, the height of the pressure head 543 rising and the force of pressing down can also be controlled by controlling the distance moved by the inclined surface 54732. A roller 57 is disposed at one end of the pressure rod 5472, and the roller 57 rolls on the first plane 54731, the inclined plane 54732, and the second plane 54733. This embodiment adopts such a component matching structure, which has a small volume, light weight, high space utilization, and lower cost.

[0044] In summary, the working principle of the antenna pressing and bending device 54 of this embodiment is as follows: the first driving device 545 first drives the second slider 548 to slide in the first slide groove 5411, wherein the first driving device 545 can be fixedly connected to the second slider 548, or fixedly connected to the driving block 5473 fixed on the second slider 548. Under the action of the elastic device 58 and the connecting rod 549, the second slider 548 drives the first slider 542 to slide together in the first slide groove 5411. When the first slider 542 moves into position, one end of the first slider 542 will abut against the limit block 530, that is, the first slider 542 no longer moves forward, and at this time, the pressure head 543 is exactly located at the position on the antenna that needs to be bent. Then, the first driving device 545 continues to drive the second slider 548 to continue to move, the elastic device 58 will be compressed, and the second slider 548 will continue to slide in the first slide groove 5411. The elastic device 58 can be a spring, a compression spring, a disc spring, etc., so it is not limited to this. In addition, the elastic device 58 can be sleeved on the connecting rod 549, so that it is convenient to install the elastic device 58. The second slider 548 will also slide on the connecting rod 549. At this time, the roller 57 located on the first plane 54731 will gradually roll onto the inclined surface 54732 as the driving block 5473 moves. When the driving block 5473 is driven to move into place, the roller 57 will roll onto and be located on the second plane 54733. One end of the pressure rod 5472 will rise as the driving block 5473 moves, and the other end will fall, and exert a descending pressure on the pressure head fixing seat 546. When the roller 57 rolls onto and is located on the second plane 54733, the pressure head 543 will be pressed down into place. At this time, the antenna pressing and bending device 54 can bend the antenna by cooperating with the antenna flipping and bending device 53. After the antenna is bent, the first driving device 545 will drive the driving block 5473 to retreat. At this time, the pressure head fixing seat 546 is no longer subjected to the downward force driven by the pressure rod 5472. The elastic force applied by the reset elastic member 520 to the pressure head fixing seat 546 will drive one end of the pressure rod 5472 and the pressure head 543 to rise together. At this time, the roller 57 located on the second plane 54733 will slowly roll along the inclined surface 54732 to the first plane 54731. When the roller 57 is located on the first plane 54731, the pressure head 543 will rise to the original position, and then the first driving device 545 will continue to drive the driving block 5473 to move outward. Under the action of the connecting rod 549, the first slider 542 will slide along with the sliding of the second slider 548, so that the antenna can be taken out. The elastic device 58 of this embodiment has a delay effect, that is, the lifting device 547 starts to drive the pressing head 543 to work only after the entire antenna pressing and bending device 54 moves into place.The reset elastic component 520 of this embodiment can not only restore the pressure head 543 to its original position, but also, when the reset elastic component 520 lifts up the pressure head fixing seat 546, the pressure head fixing seat 546 will also support one end of the pressure rod 5472, so that the roller 57 set at the other end of the pressure rod 5472 is always on the first plane 54731 or the inclined surface 54732 or the second plane 54733 at the top of the driving block 5473, thereby improving the wedging degree between the roller 57 and the driving block 5473, and improving the movement accuracy of the lifting device 547 driving the pressure head 543 to lift and lower.

The gear 5322 is sleeved on the rotating shaft (not shown in the figure) and fixedly connected with the rotating shaft. The two ends of the rotating shaft are arranged in the through holes 53251 and can rotate in the through holes 53251. The axis of the rotating shaft is arranged horizontally, so that the axis of the gear 5322 is also arranged horizontally. Then the rack 5323 is meshed with the gear 5322, and the second driving device 5324 drives the rack 5323 to move in the horizontal direction. Specifically, the second driving device 5324 drives the rack 5323 to move in the horizontal direction, thereby driving the gear 5322 to rotate, and the gear 5322 rotates to drive the rotating shaft to rotate. At this time, the bending plate 531 fixedly connected to the rotating shaft will rotate with the rotation of the rotating shaft, and the bending operation can be performed. In this embodiment, the second driving device 5324 can control the distance that the rack 5323 moves in the horizontal direction to control the rotation angle of the bending plate 531, thereby facilitating the control of the bending angle of the antenna.
