[0035] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0036] Example 1: See Figures 1 to 5 As shown, a notebook back cover assembly device includes a frame 1,

[0037] At least one multi-axis manipulator 2 is provided in the middle of the frame 1;

[0038] The front side of the frame 1 is provided with a plurality of front side material discharging trays 3 spaced from right to left, and the front side of each front side material discharging tray 3 is provided with a front side material feeding position 4;

[0039] A plurality of rear material discharging trays 5 are provided at intervals from left to right on the rear side of the frame 1, and a rear material feeding position 6 is provided on the rear side of each rear material discharging tray 5;

[0040] The multi-axis manipulator 2 is arranged between the front material discharge tray 3 and the rear material discharge tray 5;

[0041] A plurality of material transfer mechanisms 7 are also provided, each of which is disposed between the adjacent front material discharge trays and between the adjacent rear material discharge trays;

[0042] The material shifting mechanism on the front side is movably arranged between the adjacent material placing trays on the front side;

[0043] The rear material shifting mechanism is movably arranged between adjacent rear material discharging trays;

[0044] A longitudinal material shifting mechanism 8 is also provided on the left side of the frame, and the longitudinal material shifting mechanism is movably arranged between the front material discharge tray on the far left and the rear material discharge tray on the far left.

[0045] Among them, in this embodiment, a discharge cavity is provided on the front discharge tray and the rear discharge tray. The discharge cavity is provided to accommodate, support and position the rear cover. The material will be placed on the front discharge tray on the far right, and the prepared parts for the corresponding process will be placed on each front feeding position and rear feeding position, or a feeding mechanism will be directly installed to assemble the parts required for the corresponding process. The feeding mechanism can be a vibration feeding tray, a label discharge mechanism, or a tape discharge mechanism. According to the predetermined program, the multi-axis manipulator grabs the corresponding parts to be assembled on the corresponding front feeding position, and then assembles them on the back cover. Then the material shifting mechanism moves the back cover to the left and puts it on the adjacent front discharge tray. Then the multi-axis manipulator repeats the above process to assemble the parts. This cycle continues until the product moves to the leftmost front discharge tray and the parts assembly of this process is completed. Then the longitudinal material shifting mechanism moves the back cover to the leftmost rear discharge tray. Then the multi-axis manipulator repeats the above actions at the same time until the assembly process of the product on the rightmost rear discharge tray is completed. Among them, a conveyor belt 28 will be set on the right side of the rightmost rear discharge tray, so that after the back cover is assembled, the material shifting mechanism moves the back cover to the conveyor belt, and the subsequent operations can be carried out through the back-end process, such as manual storage and packaging, or sent to the back-end process through the conveyor belt.

[0046] Furthermore, in order to prevent the adjacent material shifting mechanisms from interfering with each other, the front material tray and the rear material tray are both installed on a transverse moving mechanism, which includes a bottom transverse slide rail 9, a slider 10, and a driving member that drives the slider to move transversely along the bottom transverse slide rail. The front material tray and the rear material tray are respectively installed on the corresponding sliders, and the driving member can be a combination of a ball screw 11 and a motor 12, or a rodless cylinder can be used. If a ball screw and a motor are used, the two ends of the ball screw are rotatably connected to the frame, the motor drives the ball screw to rotate, the ball screw is arranged parallel to the bottom transverse slide rail, the ball screw is rotatably connected to the slider, and when the ball screw rotates, it will drive the slider to move along the bottom transverse slide rail, thereby realizing the transverse movement of the front material tray and the rear material tray, and moving from one side of the corresponding assembly station to the other side. If a rodless cylinder is used, the slider is installed on the rodless cylinder, and the rodless cylinder is installed on the bottom transverse slide rail, which can also realize the transverse movement of the driving slider. In this embodiment, the driving member in the lateral movement mechanism is a combination of a motor and a ball screw, which converts the rotational motion into the linear motion of the slider.

[0047] See also Figure 1 , 2 As shown, there are two multi-axis manipulators, and the two multi-axis manipulators are arranged laterally at intervals.

[0048] In this embodiment, each front side material tray is a front-end assembly station of the rear cover, where an assembly process is performed, and each rear side material tray is a rear-end assembly station of the rear cover, where an assembly process is performed. Each multi-axis manipulator is responsible for the assembly processes at multiple front-end assembly stations and multiple rear-end assembly stations within its travel range, thereby realizing all assembly processes, so that fewer multi-axis manipulators can be used to realize assembly, which can reduce assembly costs.

[0049] At the same time, in the present invention, the assembly movement track of the rear cover adopts a U-shaped track, so that the assembly equipment will be close together, which can reduce the space occupied and improve the utilization rate of the space in the workshop. Of course, due to the use of fewer multi-axis manipulators, its assembly speed will be slower than the previous "I"-shaped assembly equipment with a multi-axis manipulator set for each assembly process, which is suitable for the assembly of relatively small batches of products.

[0050] Therefore, in this embodiment, the material shifting mechanism can be shortened as much as possible. Taking the material shifting mechanism between adjacent front-end assembly stations as an example, in the initial state, the front material discharge tray is on the right side of the bottom transverse slide rail. After the product is placed in the front material discharge tray, it moves to the middle of the bottom transverse slide rail, which is the assembly position. After the assembly of this process of the product is completed, it moves to the left side of the bottom transverse slide rail. Then the material shifting mechanism grabs the product, moves it a little to the left, and then places it on the front material discharge tray on the left (the front material discharge tray moves to the right side of the bottom transverse slide rail), that is, the lateral movement distance of the material shifting mechanism is slightly larger than the distance between the two adjacent bottom transverse slide rails, so that the cost can be reduced as much as possible. Among them, why not use the conveyor belt method, but use the material tray and material transfer mechanism method, so that the rack can be modularly manufactured, each material tray (front material tray or rear material tray), lateral movement mechanism and material transfer mechanism are installed on a rack module, so according to the assembly process required for the back cover of the corresponding model of notebook, the corresponding number of rack modules can be selected and assembled, and modular manufacturing and assembly can be adopted, which is more cost-effective, suitable for different customer groups, and has a wider range of applications. Moreover, the accuracy of movement and positioning will be higher than that of belts, thereby ensuring the accuracy and qualified rate of assembly.

[0051] See also Figures 1 to 3As shown, the material moving mechanism includes a vertical frame 13, a horizontal slide rail 14, a horizontal driving assembly (not shown in the figure), a vertical cylinder 15, a bracket 16, a mounting frame 17 and a plurality of suction cups 18.

[0053] Among them, when moving materials, taking the movement from right to left as an example (moving the material from the front discharge tray on the right to the adjacent front discharge tray on the left), the horizontal drive component first drives the mounting frame to move to the right, with the suction cup facing the product, and then the vertical cylinder pushes the bracket and the suction cup to move downward, so that the suction cup contacts the product, and then the product is adsorbed by the suction cup to achieve product grabbing, and then the output shaft of the vertical cylinder retracts to drive the product to move upward and separate from the front discharge tray, and then the horizontal drive component drives the mounting frame to move to the left, so that it moves to just above the front discharge tray connected to the left, and then the vertical cylinder output shaft retracts to push the bracket and the product downward, so that the product is placed on the front discharge tray, and the suction cup is released to release the product, and then the vertical cylinder output shaft retracts to drive the bracket and the suction cup to move upward, and the product moving can be completed.

[0054] Among them, the transverse drive assembly includes a transverse ball screw and a transverse motor, the transverse ball screw is arranged parallel to the side of the transverse slide rail, the two ends of the transverse ball screw are rotatably connected to the vertical frame, the transverse motor is installed on the vertical frame, the output shaft of the transverse motor is connected to one end of the transverse ball screw, and the middle part of the transverse ball screw is connected to the mounting frame. When the transverse ball screw rotates, it drives the mounting frame to move along the transverse slide rail.

[0055] The rotational motion of the lateral ball screw is converted into linear movement of the mounting frame with high precision and good stability.

[0056] See also Figure 1 , 4As shown, the longitudinal material moving mechanism 8 includes a longitudinal bracket 19, a longitudinal suction cup 20 and a first driving mechanism.

There are multiple longitudinal suction cups, and multiple longitudinal suction cups are installed at intervals at the bottom of the longitudinal bracket. The first driving mechanism is configured to drive the longitudinal bracket to move longitudinally and up and down along the left side upright frame.

[0057] In this embodiment, when it is necessary to move the product on the front discharge tray at the far left to the rear discharge tray at the far left, the first drive mechanism drives the longitudinal support to move forward so that it moves directly above the front discharge tray at the far left, and then drives the longitudinal support and the longitudinal suction cup to move downward to suck the product, and then moves the longitudinal support and the longitudinal suction cup upward to make the product leave the front discharge tray, and then drives the longitudinal support, the longitudinal suction cup and the product to move backward and move to above the rear discharge tray at the far left, and then the first drive mechanism drives the longitudinal support, the longitudinal suction cup and the product to move downward and place them on the rear discharge tray, and the longitudinal suction cup releases the adsorption of the product so that the product is placed on the rear discharge tray, and then the longitudinal support and the longitudinal suction cup move upward to complete the longitudinal movement of the product.

The first vertical cylinder is set to drive the longitudinal bracket to move up and down along the left vertical slide rail to achieve the up and down movement of the product.
