The positioning mechanism 5 is located above the transmission line 2, and its position is the screw locking position; the carrier 21 moves along the transmission line 2 to the bottom of the positioning mechanism 5, the lifting mechanism 4 starts to dock with the carrier 21 and drives the carrier 21 to move upward, and the positioning mechanism 5 fixes the position of the carrier 21; the locking mechanism 6 moves to the top of the positioning mechanism 5 through the three-axis slide module 7, and screws the carrier 21 in the fixed position.

[0044] The transmission line 2 is driven by a servo motor driven pulley structure, including two linear rails arranged along its transmission direction. The product to be processed is loaded on a carrier 21, and both ends of the carrier 21 are arranged on the linear rails. The carrier 21 moves along the linear rails with the product. A baffle 22 is arranged between the two linear rails. When the carrier 21 moves along the linear rails, it will be blocked by the baffle 22 and then be restricted below the positioning mechanism 5.

[0045] like Figure 4 and Figure 5 As shown, the lifting mechanism 4 includes an alignment plate 41 located below the carrier 21, and the alignment plate 41 is driven to rise and fall by a lead screw motor module fixedly connected to the machine platform 1. An alignment pin 42 is provided on the surface of the alignment plate 41, which will be inserted into the alignment hole provided on the carrier 21 during the lifting and lowering, thereby driving the carrier 21 to continue to move up to the working position.

[0046] like Figure 6 As shown, the three-axis slide module 7 includes an X-axis linear module 71 arranged along the transmission streamline 2, a Y-axis linear module 72 arranged horizontally on the X-axis linear module 71, and a Z-axis linear module 73 arranged vertically on the Y-axis linear module 72. The locking mechanism 6 includes a moving plate 61 arranged on the Z-axis linear module 73, and a screw gun 62 is installed on the moving plate 61. The screw gun 62 absorbs the screws from the feeding mechanism 3 by adsorption, and then reciprocates between the positions of the feeding mechanism 3 and the positioning mechanism 5 under the drive of the three-axis slide module 7, and performs locking processing on the position of each screw of the product. An upper camera 63 is also arranged on the moving plate 61, which locates the position of the screw and adsorbs it by visual monitoring.

[0047] like Figure 7 and Fig.10As shown, the positioning mechanism 5 includes a gantry-type support assembly, two sets of side plates 51 of the support assembly are fixedly arranged on both sides of the transmission streamline 2, an upper support plate 52 and a lower support plate 53 are installed between the two sets of side plates 51, the upper support plate 52 is fixedly connected to the two sets of side plates 51, and the lower support plate 53 is slidably connected to the upper support plate 52 through a linear bearing. A pressing plate assembly is installed on the lower support plate 53, and a processing hole 54 is penetrated on the pressing plate assembly corresponding to the processing position of the product, and a plurality of groups of pressing heads 55 are arranged at the bottom of the pressing plate assembly. Driven by the lifting mechanism 4, the carrier 21 will drive the pressing plate assembly and the lower support plate 53 to move vertically relative to the upper support plate 52, and the surface of the product will be in good contact with the pressing head 55 at all places, and the product is tightly pressed between the pressing plate assembly and the carrier 21, thereby achieving the positioning of the product.

[0048] A plurality of guide holes are provided on the surface of the upper support plate 52 , and guide pins 59 inserted into the guide holes are provided at corresponding positions of the lower support plate 53 . The guide holes cooperate with the guide pins 59 to limit the sliding of the lower support plate 53 relative to the upper support plate 52 .

[0049] A pressure sensing assembly 511 is installed between the upper support plate 52 and the lower support plate 53, including a pressure sensor arranged on the lower support plate 53 and a detection rod arranged at a corresponding position of the upper support plate 52. The pressure sensor and the detection rod cooperate with each other to provide feedback on the contact status between the pressure head 55 and the product and monitor the clamping force applied to the product.

[0050] As shown in the figure, the pressing head 55 includes a pressing block 56 mounted on the pressing plate assembly and a pressing rod 57 arranged at the bottom of the pressing block 56. One end of the pressing rod 57 penetrates into the pressing block 56, and the other end contacts the surface of the product. A buffer spring 58 is connected between the pressing head 55 and the pressing rod 57, so that the pressing rod 57 can apply a flexible tightening pressure to the product to prevent the product from being damaged due to excessive tightening pressure.

[0051] Furthermore, the pressing head 55 is correspondingly arranged on the side of the processing hole 54 to provide support for the processing position during processing, which can better maintain the stability of the product at the processing position and enhance the positioning capability of the product.

[0052] like Figure 8 and Fig.10 As shown, the pressure plate assembly includes an upper pressure plate 512 and a lower pressure plate 513 which are arranged opposite to each other, a pressure head 55 is installed on the lower pressure plate 513, and the upper pressure plate 512 is located above the pressure head 55. A stepped groove 516 is arranged at the bottom of the lower support plate 53, and both sides of the lower pressure plate 513 are clamped in the stepped groove 516; at the same time, a plurality of vertically arranged positioning pins 510 are arranged on the upper surface of the lower support plate 53, and a positioning hole for inserting the matching positioning pins 510 is arranged on the upper pressure plate 512, and the position of the pressure plate assembly on the lower support plate 53 is limited by the above structure.

[0053] Furthermore, a plurality of groups of endoscopes 514 are vertically arranged on the pressure plate assembly for real-time monitoring of the status of the products on the carrier 21 .

[0054] Furthermore, the pressure plate assembly is provided with an indicator light 515 at the position corresponding to each group of processing holes 54. The indicator light 515 is electrically connected to the control center, and can receive the working signal feedback from the control center during the screw locking process, and emit a warning light of a corresponding color. For example, if the screw locking is normal, the corresponding indicator light 515 emits a normal indication light; and if there is an installation failure of the screw, the corresponding indicator light 515 emits an alarm message, the device automatically removes the screw at the fault position, and controls the locking mechanism 6 to reset to the initial position, and reinstalls the screw.

[0055] In order to save the space occupied by the entire device, the present embodiment sets the conveying mode of the carrier 21 to vertical conveying, and the transfer of the carrier 21 is achieved by the steering streamline 8 and the steering mechanism 9. Fig.11 and Fig.12 As shown, the steering streamline 8 is arranged on the machine 1. The steering streamline 8 is located at the end of the transmission streamline 2 and is perpendicular to the transmission direction of the transmission streamline 2. The carrier 21 is processed on the transmission streamline 2 and then transferred to other workstations along the steering streamline 8.

[0056] Like the transmission streamline 2, the steering streamline 8 also adopts a motor-driven pulley structure for transmission, and the steering streamline 8 is lower than the transmission streamline 2; the steering mechanism 9 includes a lifting plate 91 arranged on the steering streamline 8 and a transition roller group 92 arranged on the lifting plate 91, and the transition roller group 92 is located at the end of the transmission streamline 2 and is arranged in the same direction as the transmission streamline 2. A vertical driving member is arranged at the bottom of the lifting plate 91, which is used to drive the transition roller group 92 to a position higher than the steering streamline 8, and then drive the carrier 21 to leave the upper surface of the steering streamline 8. The transition roller group 92 is composed of a power roller, which can drive the carrier 21 to transfer to the transmission streamline 2 in a direction perpendicular to the steering streamline 8.

[0057] In this embodiment, the vertical driving member is a lifting cylinder 93 disposed at the bottom of the lifting plate 91. Further, a carrier sensor 94 is disposed on the lifting plate 91 for determining whether the carrier 21 is in place.

[0058] Furthermore, a stopper 81 is also provided on the side of the transition roller set 92, and the stopper 81 is located at the end of the steering streamline 8. The surface of the stopper 81 has an elastic slope arranged in the same direction as the steering streamline 8. When the carrier 21 moves toward the transition roller set 92, it moves along the short side of the elastic slope toward the long side and gradually squeezes the elastic slope; when the carrier 21 passes through the stopper 81, the elastic slope returns to the initial position, playing a role in preventing the carrier 21 from retreating.

[0059] In order to ensure the yield of the entire automated locking process, the present embodiment provides a plurality of detection systems for real-time monitoring of the locking status of the screws. The detection systems are electrically connected to a control center, and the control center issues control instructions to other drive components of the present invention based on feedback information from the detection mechanism.

[0060] Specifically, Figure 2 As shown, a torque tester 11 is provided on the machine 1 , which can detect the torque of the screw gun 62 removing the screws from the feeding mechanism 3 .

[0061] A visual inspection mechanism is also provided between the feeding mechanism 3 and the positioning mechanism 5, including a positive camera 12 horizontally mounted on the machine platform 1 and a lower camera 13 vertically mounted on the machine platform 1. After the screw gun 62 sucks the screw, it is placed at the intersection of the positive camera 12 and the lower camera 13. The lower camera 13 visually aligns the central axis of the screw to determine whether the position of the screw is correct; the positive camera 12 visually determines the length and thread shape of the screw. After the screw is inspected and qualified, it is transferred to the positioning mechanism 5 for locking processing.

[0062] In addition, multiple sensors for sensing the position of the vehicle 21 are disposed on the transmission streamline 2 and the turning streamline 8. Since this technology is very mature in the prior art, it will not be described in detail here.

[0063] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
