[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts should fall within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 4 The PCB assembly device in one embodiment of the present invention includes a limit member 1 for fixing the housing, a material picking head 2 and a pressing head 3 installed in conjunction with the limit member 1, and a pressing component 4 that can apply pressure to the material picking head 2 or the pressing head 3; the material picking head 2 and the pressing head 3 can be driven to move to the assembly position respectively.

[0034] Among them, when the material picking head 2 obtains the PCB and moves to the assembly position, the pressing component 4 drives the material picking head 2 close to the limiter 1 to pre-press the PCB on the shell; when the pressing head 3 moves to the assembly position, the pressing component 4 drives the pressing head 3 close to the limiter 1 to press the PCB on the shell.

[0035] When assembling the PCB into the housing, the pick-up head 2 is first driven to pick up the PCB and move it to the assembly position. The pressing assembly 4 then performs a first pre-press on the pick-up head 2, initially pressing the PCB into the housing on the stopper 1. The pressing head 3 is then driven to the assembly position, and the pressing assembly 4 performs a second press on the pick-up head 2, securing the PCB firmly in the housing.

[0036] Reference Figure 3 and Figure 4The material removal head 2 and the pressing head 3 are both connected to a moving assembly 5, which includes an abutting end. When the pressing assembly 4 presses the abutting end, the moving assembly 5 drives the material removal head 2 or the pressing head 3 toward the stopper 1; when the pressing assembly 4 moves away from the abutting end, the moving assembly 5 drives the material removal head 2 or the pressing head 3 away from the stopper 1.

[0037] Reference Figure 3 and Figure 5 The moving component 5 includes a connecting member 51, a mounting seat 52 and a reset member 53. The connecting member 51 is movably connected to the mounting seat 52 and is fixedly connected to the material taking head 2 or the pressure head 3. The abutting end is the end of the connecting member 51 away from the material taking head 2 or the pressure head 3. The reset member 53 is cooperated with the connecting member 51 to make the material taking head 2 or the pressure head 3 close to the mounting seat 52.

[0038] Therefore, when the pressing assembly 4 presses the connecting member 51, it can drive the material removal head 2 or the pressing head 3 to move, thereby completing the pressing work of the PCB. When the pressing assembly 4 moves away from the connecting member 51, the return member 53 can drive the material removal head 2 or the pressing head 3 to move closer to the mounting seat 52, thereby facilitating the next pressing work.

[0039] Specifically, refer to Figure 5 The connecting member 51 includes an abutment plate 511 and a connecting rod 512, which are fixedly connected to each other. The connecting rod 512 is slidably inserted into the mounting seat 52. The reset member 53 includes an elastic body, one end of which is fixedly connected to the abutment plate 511 and the other end is fixedly connected to the mounting seat 52. The elastic body has elastic potential energy that forces the material removal head 2 or the pressure head 3 to approach the mounting seat 52. In this embodiment, the elastic body can be configured as a spring, and the material removal head 2 can use a vacuum suction cup. The reset member 53 is configured as an elastic body, which can promptly reset the material removal head 2 or the pressure head 3.

[0040] The elastic element allows the pick-up head 2 to effectively adhere to the PCB when it is being picked up, and also allows the pick-up head 2 and the pressing head 3 to effectively adhere to the PCB during press-fitting. Furthermore, the elastic element ensures that pressure is relatively uniform at every position of the pick-up head 2 and the pressing head 3 during the press-fitting process.

[0041] Reference Figure 1 The PCB assembly equipment of this embodiment also includes a first drive component 6 for driving the picking head 2 to move, and a rotary loading component 7 installed in conjunction with the first drive component 6. The first drive component 6 drives the picking head 2 to move to the loading position of the rotary loading component 7 to obtain the PCB, and drives the picking head 2 to move to the assembly position.

[0042] Reference Figure 3In this embodiment, the first drive assembly 6 includes a fixed frame 61, a connecting plate 62 slidably connected to the fixed frame 61, and multiple driving members that cooperate to drive the connecting plate 62 to move. The reclaiming head 2 is mounted on the connecting plate 62 via the moving assembly 5. The multiple driving members can cooperate to drive the reclaiming head 2 to the loading position of the rotary loading assembly 7 or to the assembly position.

[0043] Reference Figure 6 The rotary loading assembly 7 includes a rotary drive 71 and a mounting plate 72 fixed to the output end of the rotary drive 71. The mounting plate 72 includes at least two mounting stations for supporting PCBs, each of which can be rotated to a loading position. In this embodiment, the rotary loading assembly 7 is mounted to the side of the fixed frame 61. When the mounting station with the PCB rotates to the loading position, the first drive assembly 6 drives the pick-up head 2 to the loading position to retrieve the PCB.

[0044] Reference Figure 4 The pressing assembly 4 includes a mounting frame 41, a pressing driver 42 mounted on the mounting frame 41, a pressing block 43 mounted at the output end of the pressing driver 42, and a pressure sensor 44 mounted in conjunction with the pressing block 43. The pressing driver 42 drives the pressing block 43 to move up and down, thereby abutting or moving away from the abutting end of the moving assembly 5. The pressure sensor 44 can obtain and control the pressure value of the pressing head 3 in real time, thereby reducing the possibility of PCB damage.

[0045] Reference Figure 4 The PCB assembly equipment of this embodiment further includes a second driving component 8 that drives the pressure head 3 to move. Figure 5 The second drive assembly 8 includes an adapter plate 81 fixedly connected to the mounting bracket 41 and a second drive member 82 mounted on the adapter plate 81. The discharging head 2 is mounted to the output end of the second drive member 82 via the moving assembly 5. In this embodiment, the second drive member 82 can be a pneumatic cylinder to drive the ram 3 to and from the assembly position.

[0046] Therefore, when the PCB assembly equipment is in operation, the first drive assembly 6 first drives the reclaiming head 2 to the assembly position, and then uses the pressing assembly 4 to press the abutting end of the movable assembly 5 connected to the reclaiming head 2, so that the reclaiming head 2 can pre-press the PCB into the housing. Next, the first drive assembly 6 drives the reclaiming head 2 away from the assembly position, and the second drive assembly 8 drives the pressing head 3 to the assembly position, and again uses the pressing assembly 4 to press the abutting end of the movable assembly 5 connected to the pressing head 3, so that the pressing head 3 can press the PCB into the housing.

[0047] Reference Figure 1 and Figure 2The PCB assembly equipment of this embodiment also includes a conveyor assembly 9 and a lifting member 10 mounted in conjunction with the conveyor assembly 9. The lifting member 10 drives the stopper 1 to disengage from or abut against the conveyor assembly 9. When the lifting member 10 drives the stopper 1 away from the conveyor assembly 9, the pressing assembly 4 cooperates with the material removal head 2 and the pressing head 3 to press the PCB onto the housing. The conveyor assembly 9 is a common conveying device in the art and will not be described in detail in this embodiment. The lifting member 10 can be a lifting cylinder, and the stopper 1 can be a pallet.

[0048] In this embodiment, the shapes of the material removal head 2 and the pressing head 3 are adapted to the shape of the PCB. The contoured design enables the material removal head 2 and the pressing head 3 to effectively fit the PCB, thereby enhancing the pressing effect.

[0049] Reference Figure 1 and Figure 7 The PCB assembly equipment of this embodiment also includes an ion fan 11 for removing static electricity from the finished PCBs and a visual inspection camera 12 for inspecting the assembly status of the finished PCBs. After the PCBs are assembled, the ion fan 11 removes static electricity from the assembled product, while the visual inspection camera 12 inspects the assembly status of the PCBs, ensuring the assembly quality.
