[0006] To ensure accurate separation of products and scraps during circuit board cutting and to prevent loosening or shifting, an automated circuit board cutting platform is provided to work in conjunction with automated circuit board conveying and cutting devices to complete the entire cutting process.

[0007] An automatic circuit board cutting platform includes a grooved lower mold and a cover upper mold that interlock with each other. Both the grooved lower mold and the cover upper mold are mounted on a moving platform. The cover upper mold is driven by an opening and closing component. A cutting line through groove is provided in the cover upper mold corresponding to the grooved lower mold.

[0008] Furthermore, the mobile platform includes a displacement driver, on which a support frame is driven and connected. The lower groove mold, the upper cover mold, and the opening and closing assembly are all mounted on the support frame.

[0009] Furthermore, the displacement actuator includes a lead screw linear slide, and the bottom of the support frame is connected to the slider of the lead screw linear slide.

[0010] Furthermore, the bottom sides of the support frame are respectively connected to a lead screw linear slide and a linear guide rail, and the lead screw linear slide and the linear guide rail are parallel to each other.

[0011] Furthermore, both ends of the lead screw linear slide are equipped with slider sensors, which are electrically connected to the lead screw linear slide.

[0012] Furthermore, the support frame is provided with a mating screw hole, and a bolt that is threadedly connected to the mating screw hole is connected to the lower mold of the groove.

[0013] Furthermore, the opening and closing assembly includes an upper mold frame and a translation push rod, with the cover plate mold detachably installed in the upper mold frame, and the front end of the translation push rod connected to the upper mold frame.

[0014] Furthermore, frame guide rails are provided on both the left and right sides of the upper mold frame, and the frame guide rails are parallel to the translation push rod.

[0015] Furthermore, the opening and closing assembly includes a lifting push rod, the front end of which is vertically connected to the bottom of the upper mold frame.

[0016] Furthermore, a guide slide rod is slidably connected to the bottom of the upper mold frame, and the guide slide rod is parallel to the lifting push rod.

[0017] The advantages of this utility model are:

[0018] 1. It can accurately place and position the circuit board to be cut, and automatically transport the circuit board between multiple processing stations to ensure the cutting quality and processing efficiency of the circuit board.

[0019] 2. The circuit board products and scraps obtained after cutting are stably placed in the grooved lower mold, which facilitates separation and processing using automated equipment such as robotic arms.

[0033] like Figures 1 to 5 As shown, this embodiment provides an automatic circuit board cutting platform, including a grooved lower mold 1 and a cover upper mold 2 that are interlocked. Both the grooved lower mold 1 and the cover upper mold 2 are mounted on a moving platform 3. The cover upper mold 2 is driven to be connected to an opening and closing component 4. A cutting line through groove 201 is provided in the cover upper mold 2 corresponding to the grooved lower mold 1.

[0034] In practical use, a suction cup robotic arm can be installed at one end of the mobile platform 3 in this embodiment for loading and unloading materials, or the circuit board to be cut can be placed into the lower mold 1 of the groove by manual operation. The other end of the mobile platform 3 is equipped with a board splitting cutter. After the upper mold 2 of the cover plate is driven to close by the opening and closing component 4, the mobile platform 3 transports the circuit board to the position of the board splitting cutter. The board splitting cutter cuts the circuit board along the cutting line through groove 201. After the cutting is completed, the mobile platform 3 returns to the loading and unloading position, and the upper mold 2 of the cover plate opens to remove and separate the cut circuit board products and scraps from the lower mold 1 of the groove.

[0035] The mobile platform 3 includes a displacement driver, on which a support frame 301 is driven. The lower groove mold 1, the upper cover mold 2, and the opening / closing assembly 4 are all mounted on the support frame 301. The displacement driver includes a lead screw linear slide 302, and the bottom of the support frame 301 is connected to the slider of the lead screw linear slide 302. The upper and lower molds are driven as a single unit by the lead screw linear slide 302, resulting in good operational stability and preventing shaking and displacement of the circuit board during transportation.

[0036] The bottom sides of the support frame 301 are respectively connected to a lead screw linear slide 302 and a linear guide rail 303, which are parallel to each other. The lead screw linear slide 302 and the linear guide rail 303 work together to ensure that the various mechanisms installed on the support frame 301 can move stably and accurately.

[0037] Both ends of the lead screw linear slide 302 are equipped with slider sensors 5, which are electrically connected to the lead screw linear slide 302. The slider sensors 5 can be commercially available photoelectric switches, which automatically stop running after the lead screw linear slide 302 drives the support frame 301 to the endpoint. This can improve the movement and positioning accuracy of the moving platform 3 and prevent equipment failure caused by the cutter misalignment failing to be accurately placed into the cutting line through groove 201 during cutting.

[0038] The support frame 301 is provided with a mating screw hole 6, and a bolt 7 threadedly connected to the mating screw hole 6 is threaded onto the grooved lower mold 1. The grooved lower mold 1, which is fixed by the bolt 7, can be quickly assembled and disassembled, so that different molds can be installed on the platform according to different circuit board products.

[0039] The opening and closing assembly 4 includes an upper mold frame 401 and a translation push rod 402. The upper mold plate 2 is detachably installed in the upper mold frame 401, and the front end of the translation push rod 402 is connected to the upper mold frame 401. In this embodiment, similar to the replaceable lower mold, the upper mold is also connected to the upper mold frame 401 by bolts 7 for easy replacement. The translation push rod 402 drives the upper mold frame 401 to move back and forth, thereby realizing the automatic opening and closing of the upper mold plate 2.

[0040] Frame guide rails 403 are provided on both the left and right sides of the upper mold frame 401, and the frame guide rails 403 are parallel to the translation push rod 402. The frame guide rails 403 can improve the running stability of the upper mold frame 401 and ensure accurate positioning.

[0041] The opening and closing assembly 4 includes a lifting push rod 404, the front end of which is vertically connected to the bottom of the upper mold frame 401. In addition to the horizontal opening and closing design, the opening and closing assembly 4 in this embodiment also has a vertical lifting function; the upper mold 2 of the cover plate rises upwards and then retracts laterally to expose the opening of the lower mold 1 in the groove. This avoids frictional wear between the lower mold 1 in the groove and the upper mold 2 of the cover plate during horizontal opening and closing, and improves the tightness of the lower mold 1 in the groove and the upper mold 2 of the cover plate when they are closed.

[0042] The bottom of the upper mold frame 401 is slidably connected to a guide slide rod 8, which is parallel to the lifting push rod 404. The guide slide rod 8 can assist the lifting push rod 404 in providing support and guidance, reducing the operating load of the lifting push rod 404, and preventing the cover plate mold 2 from shaking and shifting when it is raised and lowered.

[0043] The opening and closing assembly 4 in this embodiment has the following specific structural layout: a lifting push rod 404 is mounted on the support frame 301, the top of the lifting push rod 404 is connected to the frame guide rail 403, the upper mold frame 401 is slidably connected to the frame guide rail 403, and a translation push rod 402 is mounted on the side of the frame guide rail 403 with its front end connected to the upper mold frame 401. The guide slide rod 8 is vertically mounted at the bottom of the frame guide rail 403 and is sleeved in the linear bearing 801 mounted on the support frame 301.

[0044] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
