[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention. Example

[0046] See also Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a sub-hanging assembly and disassembly device for surface treatment of metal frames of electronic products, which includes a frame 1, a material tray loading and unloading assembly 2, a variable distance mechanism 5, a sub-hanging positioning and unlocking assembly 4, and an assembly and disassembly robot assembly 6;

[0047] The tray loading and unloading assembly 2 is arranged on the frame 1, and is used for feeding the metal frame of the electronic product that has not been surface treated and unloading the metal frame of the electronic product that has been surface treated;

[0048] The distance-changing mechanism 5 is arranged on the frame 1, and is used to position the metal frames of the electronic products arranged in parallel and ensure a set distance between the metal frames of the adjacent electronic products;

[0049] The sub-hanger positioning and unlocking component 4 is arranged on the frame 1, and is used to position the sub-hanger and open the locking mechanism (elastic card) on the sub-hanger for clamping the metal frame of the electronic product;

[0050] See also Figure 4 and Figure 5 The assembly and disassembly manipulator assembly 6 includes a multi-axis manipulator 60 disposed on the frame 1, and an assembly and disassembly gripper assembly 61 for picking up and placing the metal frame of the electronic product. The multi-axis manipulator 60 has high flexibility, is convenient for the layout of the matching equipment, and has little restriction on the picking and placing method of the matching equipment. The assembly and disassembly gripper assembly 61 includes an assembly and disassembly connection seat 610, an assembly and disassembly gripper beam 611 slidably connected to the assembly and disassembly connection seat 610, and an assembly and disassembly finger cylinder 612 arranged on the assembly and disassembly gripper beam 611. Since the working distance between adjacent assembly finger cylinders 612 is small, the clamping claws of the assembly finger cylinders 612 are thin and easily deformed and damaged when subjected to a large impact. An assembly elastic member 613 is connected between the assembly connection seat 610 and the assembly clamping claw beam 611 to cushion the impact on the assembly finger cylinder 612 during collision. At the same time, a pressure sensor 614 is arranged between the assembly connection seat 610 and the assembly clamping claw beam 611 to prevent the clamping claws of the assembly finger cylinder 612 from being damaged, deformed or broken due to excessive pressure on the clamping claws when working abnormally. At the same time, a rubber clamping claw sleeve is arranged on the clamping claw sleeve of the assembly finger cylinder 612 to play a buffering and dynamic compensation function and reduce damage to the metal frame of the electronic product.

The two pitch-changing pullers 51 are respectively connected to the left and right outermost pitch-changing sliders 521, so that the pitch-changing sliders 521 spread to both sides when changing the pitch, so as to avoid a large distance error between the leftmost pitch-changing slider 521 and the rightmost pitch-changing slider 521 due to error accumulation. The limiting rod 520 is fixedly connected to one of the variable distance sliders 521. The limiting rod 520 penetrates another adjacent variable distance slider 521 and a limiting protrusion is provided at the end of the limiting rod 520. The outer diameter of the limiting protrusion (not shown in the figure) is larger than the through hole through which the limiting rod 520 penetrates the variable distance slider 521. When the distance is changed, the variable distance slider 521 penetrated by the limiting rod 520 pulls the adjacent variable distance slider 521 through the limiting rod 520. The variable distance positioning block 523 is provided with a variable distance positioning surface 522 on the top thereof, which is in contact with the outer periphery of the metal frame of the electronic product. The variable distance positioning surface 522 is provided with a vacuum suction nozzle 524 for adsorbing the metal frame of the electronic product. In order to facilitate clamping, the adjacent two sides of the variable distance positioning block 523 are not provided with retaining edges, and the outer sides of the two outermost variable distance positioning blocks 523 are provided with retaining plates (not shown in the figure) to prevent the metal frame of the electronic product from falling off the variable distance positioning block 523 when the distance is changed. Because of its small size, it can also avoid adjacent matching equipment.

[0052] In order to facilitate automated operation, the variable distance frame 50 is provided with a variable distance material shortage detection sensor 55 for detecting whether there is a metal frame of the electronic product in the variable distance positioning block 523.

The variable distance mechanism 5 also includes a horizontally movable variable distance code scanning linear module 53 and a variable distance code scanning camera 54 arranged on the variable distance code scanning linear module 53. The moving direction of the variable distance code scanning linear module 53 is parallel to the moving direction of the variable distance slider 521. The variable distance positioning block 523 is provided with an avoidance groove 5230 for avoiding the angle of view between the variable distance code scanning camera 54 and the identification code on the metal frame of the electronic product. Please refer to Fig.19 A variable distance positioning block 523 is placed in the metal frame of the electronic product.
