[0055] The product assembly machine 5 includes a PCB module cache line 51, a PCB module storage area 52 and a product assembly area 53;

[0056] The PCB module 100 is moved to the PCB module cache line 51 by the PCB material taking robot 11, and the PCB module 100 is moved to the PCB module storage area by the material storing robot 54;

[0057] Alternatively, the PCB module is moved to the PCB module cache line 51 by the PCB material picking robot 11, and is moved to the product assembly area by the product assembly robot 55 and assembled with the product.

[0058] In this embodiment, Figures 4 to 10 As shown, the small iron piece loader 2 includes a small iron piece loader platform 22 and a flexible vibration disk 23, a small iron piece pre-feeding arm 24, a film tearing mechanism 25 and a small iron piece buffer area 26 arranged thereon, and a small iron piece feeding claw 241 is installed at the end of the small iron piece pre-feeding arm 24.

The release film pneumatic clamp 253 is fixed to the moving plate 255. The release film waste box 252 is located directly below the release film pneumatic clamp 253. The film tearing drive cylinder 254 drives the moving plate 255 to move and drive the release film pneumatic clamp 253 to move, thereby tearing off the release film on the bottom surface of the small iron piece. In this embodiment, the inner wall surface of the release film pneumatic clamp is provided with saw teeth for increasing the clamping force.

[0060] In this embodiment, Figure 7 and Figure 8As shown, the surfaces of the movable plate 255 and the film tearing bracket 251 are both provided with an arc groove 2511 for adjusting the installation angle of the film tearing driving cylinder in the XZ plane. The film tearing driving cylinder is a slide cylinder, and the sliding direction of the slide of the slide cylinder forms a certain angle with the X-axis. When the release film is torn off, it is torn off obliquely, which facilitates the release film to be torn off more smoothly. The arc groove is provided to facilitate adjusting the installation angle of the film tearing driving cylinder based on it, that is, to facilitate adjusting the film tearing angle, so as to ensure that the release film is torn off more smoothly.

[0061] In this embodiment, Fig. 9 and Fig.10 As shown, the small iron piece cache area 26 includes a cache table 261, a first cache positioning mechanism 262 and a second cache positioning mechanism 263. The cache table 261 is provided with a plurality of cache cavities 2611 for placing small iron pieces. The adjacent two sides of the cache cavity are respectively provided with a first positioning side edge 2612 and a second positioning side edge 2613. The first cache positioning mechanism 262 is opposite to the first positioning side edge 2612, and the second cache positioning mechanism 263 is opposite to the second positioning side edge 2613. The positioning of the small iron piece 102 in the cache cavity 2611 is achieved through the cooperation of the first cache positioning mechanism 262 and the first positioning side edge 2612 and the second cache positioning mechanism 263 and the second positioning side edge 2613.

[0062] In this embodiment, Fig. 9 and Fig.10 As shown, the first cache positioning mechanism 262 includes a first cache driving cylinder 2621 and a cache vertical plate 2622, wherein the cache vertical plate 2622 is installed at the power output end of the first cache driving cylinder 2621, and the first cache driving cylinder 2621 drives the cache vertical plate 2622 to translate along the Y direction to align the plurality of small iron pieces 102 with the first positioning side edge 2612 as a reference;

[0063] The second cache positioning mechanism 263 includes a second cache driving cylinder 2631 and a cache connecting plate 2632. The cache connecting plate 2632 is installed at the power output end of the second cache driving cylinder 2631. The upper end of the cache connecting plate 2632 extends upward to form a plurality of cache positioning columns 2633. The cache positioning columns 2633 pass through the cache cavity 2611 from bottom to top. The second cache driving cylinder 2631 drives the cache connecting plate 2632 to translate along the X direction to align a plurality of small iron pieces 102 with the second positioning side edge 2613 as a reference.

[0064] The second cache positioning mechanism has an ingenious structural design. A second cache driving cylinder can drive multiple cache positioning columns to translate along the X direction at the same time to achieve positioning and clamping of multiple small iron pieces in the X direction.

[0065] By setting up the buffer area, small iron parts with the release film torn off can be temporarily stored and positioned, making it easier for the small iron parts picking robot at the back to accurately position them and take them to the pressing assembly line.

[0066] In this embodiment, Fig.12 As shown, the first fixture 42 includes a plurality of profiling cavities 421, two adjacent sides of the profiling cavity 421 are positioning reference sides 422, and the other two adjacent sides are provided with a mobile positioning drive unit 423, each of which includes a mobile positioning drive cylinder 4231 and a positioning side plate 4232, and the positioning side plate 4232 is installed at the power output end of the mobile positioning drive cylinder 4231. The positioning side plate 4232 is driven by the mobile positioning drive cylinder 4231 to translate and cooperate with the positioning reference side 422 on the opposite side, so as to position the PCB 101 in the profiling cavity 421 of the first fixture, so as to avoid the PCB from moving off during the pressing process, and ensure the installation accuracy of small and large iron parts on the PCB.

[0067] In this embodiment, the PCB module cache line 51 is provided with a second fixture 511 , and the second fixture 511 can translate along the X direction with the PCB module cache line 51 .

[0068] In this embodiment, Fig.13 and 14 As shown, the product assembly area 53 includes a screw feeding device 531, a stopping mechanism 532 for stopping the product 200 on the assembly line 6, and a side push positioning mechanism 533 for side push positioning of the product on the assembly line. The end of the product assembly manipulator 55 is provided with an automatic screw locking electric screwdriver with an automatic screw locking function and a material picking air claw for grabbing the PCB module. The screw feeding is realized by the screw feeding device 531, and the product assembly manipulator 55 drives the material picking air claw to move the PCB module 100 to the product 200 on the assembly line. The product assembly manipulator 55 drives the automatic screw locking electric screwdriver to grab the screws and tighten the screws to assemble the PCB module 100 and the product 200 together. The automatic screw locking electric screwdriver, the material picking air claw, and the visual detection positioning are all related to the prior art and are not described in detail and are not shown in the figure.

[0069] In this embodiment, Fig.13 and 14 As shown, the stop mechanism 532 includes a stop driving cylinder 5321 and a stop plate 5322. The stop plate 5322 is installed at the power output end of the stop driving cylinder 5321.

The side-push plate 5332 is installed at the power output end of the side-push driving cylinder 5331. The side-push driving cylinder drives the side-push plate to translate along the Y direction to position the product (the line body bracket on the opposite side of the side-push positioning mechanism on the assembly line is used as the positioning reference).

[0071] like Figures 1 to 4 as well as Fig.11 As shown, an assembly method using the notebook PCB module automatic assembly line, the assembly method comprises the following steps:

[0072] Step 1: PCB 101, small iron piece 102 and large iron piece 103 are respectively loaded by a PCB loading machine, a small iron piece loading machine and a large iron piece loading machine;

[0073] Step 2, the first jig flows with the pressing line body, and the PCB 101 is grabbed from the PCB feeder to the first jig at the PCB feeding area of ​​the pressing line body by the PCB material taking manipulator 11, and the small iron piece 102 is grabbed from the small iron piece feeder to the first jig in the small iron piece feeding area by the small iron piece taking manipulator 21, and the small iron piece is pressed to the surface of the PCB by the small iron piece pressing device;

[0074] Step 3: grab the large iron piece 103 from the large iron piece feeding machine to the first fixture in the large iron piece feeding area by the large iron piece taking manipulator 31, and press the large iron piece to the surface of the PCB by the large iron piece pressing device to form a PCB module;

[0075] A code scanning device may also be provided at the large iron piece pressing device to scan and bind the pressed and assembled PCB modules and save the current data.

[0076] Step 4: Move the PCB module to the PCB module cache line by the PCB material taking manipulator. The PCB module can be translated and transported along the X direction together with the second fixture. Move the PCB module to the PCB module storage area by the material storage manipulator 54. This situation is mainly when the assembly line for assembling products is not connected later or the assembly line fails, etc., resulting in the beat not keeping up. The assembled PCB module can be temporarily stored, which will not affect the assembly efficiency of the PCB module assembly itself and fully utilize the production capacity of the assembly line.

[0077] Alternatively, the PCB module is moved to the PCB module cache line by the PCB material taking robot, and is moved to the product assembly area and assembled with the product by the product assembly robot 55. This situation is mainly when docking with the assembly line for assembling products, and can be compatible with the assembly line, and the assembled PCB module can be directly assembled to the product (such as the shell of a notebook), thereby improving the automation of the entire assembly process and the compatibility with the assembly line.

[0078] Among them, in step one, PCBs and large iron parts are both loaded on stacked trays, with multiple PCBs and large iron parts placed on each layer of trays. The PCB is grabbed by a PCB picking robot and placed in the PCB loading area, and the large iron part is grabbed by a large iron part picking robot and placed in the large iron part loading area. The empty trays will be taken away by other mechanisms. This loading method is a prior art, so it will not be repeated.

[0079] The feeding process of small iron pieces is as follows: when small iron pieces are fed, they have release film on the bottom, and are fed by vibrating the flexible disk. Under the action of vibration, there is always a small iron piece with the release film facing downwards. The visual inspection unit for detecting the front and back sides of the small iron pieces provided in the small iron piece pre-feeding arm 24 can detect which small iron piece has the release film facing downwards, and then the small iron piece pre-feeding arm drives the small iron piece feeding air claw to grab the small iron piece in this state and move it to the film tearing mechanism. At this time, the small iron piece is always grabbed by the small iron piece feeding air claw, and because there will be ears on the edge of the release film, the release film pneumatic clamp clamps the extended edge or ear of the release film, and then the film tearing drive cylinder drives the moving plate to move obliquely The pneumatic clamp of the release film is driven to move obliquely to tear off the release film on the bottom of the small iron piece. Then the small iron piece pre-picking arm drives the small iron piece picking claw to place the small iron piece into the cache cavity of the cache table, and the first cache driving cylinder 2621 drives the cache vertical plate 2622 to translate along the Y direction to align several small iron pieces 102 with the first positioning side edge 2612 as the reference; the second cache driving cylinder 2631 drives the cache connecting plate 2632 to translate along the X direction to align several small iron pieces 102 with the second positioning side edge 2613 as the reference, so as to realize the precise positioning of the small iron piece on the cache table, and then the small iron piece picking robot grabs it to the small iron piece loading area.

[0080] In this embodiment, the small iron piece pressing device and the large iron piece pressing device in step two and step three are both conventional pressing machines, which can perform pressing and pressure maintenance according to pressing requirements. This is the prior art and will not be described in detail.

[0081] In this embodiment, there are two pressing assembly lines, each of which has double workstations (that is, there are two first fixtures that can press and assemble two PCBs in turn). This design is to match the production rhythm and make full use of production capacity. The number of pressing assembly lines and the number of workstations on each line can be adjusted as needed.

[0082] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structures made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
