Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board separation technology, and in particular to a circuit board trimming and separation device. Background Technology
[0002] Existing PCB depaneling machines typically first transport the PCB to a trimming station, where the trimming mechanism cuts the copper foil edges. Then, the PCB is transported to a depaneling station where a depaneling mechanism performs the depaneling. However, because the trimming mechanism uses a cutting blade to cut the four copper foil edges of the PCB sequentially, the cutting efficiency is low. Furthermore, because the PCB is prone to shifting during transport, a visual inspection is required before depaneling, and the PCB is corrected based on the inspection results. While this improves the accuracy of the depaneling process, it also results in a longer depaneling cycle. Summary of the Invention

[0007] Furthermore, the trimming mechanism includes a movable seat that can move along the Z-axis and Y-axis directions; two slide blocks are slidably connected to the side of the movable seat facing the center of the cutting table, and a cutting module is rotatably connected to the slide blocks; the sliding direction of the slide blocks is parallel to the circuit board support surface of the turntable in an inclined state; the cutting module can rotate 90° relative to the slide blocks around the Z-axis direction.
[0008] Furthermore, in the two trimming mechanisms, the Y-direction trimming length of one of the cutting modules is less than half the length of the Y-direction circuit board copper foil edge material, while the Y-direction trimming length of the other cutting module is greater than half the length of the Y-direction circuit board copper foil edge material.

[0012] Furthermore, the cutting table is provided with a cutting slit to avoid the laser emitted by the laser cutting head.
[0013] The beneficial effects of this utility model are as follows: The circuit board trimming and separation device of this utility model uses two turntables to adsorb and fix the circuit board, and uses a separation and cutting mechanism to separate and cut the circuit board; after the separation and cutting is completed, the turntable drive assembly drives the two turntables to rotate together to an inclined state; the two trimming mechanisms first trim the copper foil edge material of the two X-direction circuit boards respectively, and then jointly trim the copper foil edge material of the two Y-direction circuit boards, thereby completing the trimming and separation of the circuit board; the trimming efficiency of this circuit board trimming and separation device is high, and the circuit board does not need to be moved during the separation and trimming process, so the trimming and separation operation has high precision, compact operation cycle, and high efficiency.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figs. 1 to 3As shown, a circuit board trimming and slitting device includes a base 1, on which a cutting table 2 is connected. Turntables 3 are rotatably mounted on both sides of the cutting table 2. The top surface of each turntable 3 has several vacuum adsorption holes 31 for adsorbing and fixing the circuit board. The two turntables 3 are connected to a turntable drive assembly 4 that drives them to rotate towards each other to an inclined state or to rotate away from each other to a horizontal state. Above the cutting table 2, there are two trimming mechanisms 6 and a slitting and cutting mechanism 5 located between the two trimming mechanisms 6. The slitting and cutting mechanism 5 is used to slitting and cutting the circuit board located on the cutting table 2. The two trimming mechanisms 6 are used to trim the copper foil edges of the circuit board on the two turntables 3 in an inclined state.
[0019] Specifically, such as Fig. 1 and 2 As shown, the end of the turntable 3 closest to the cutting table 2 is rotatably connected to the base. In the initial state, the top surfaces of the two turntables are flush with the top surface of the cutting table 2. When the turntable drive assembly 4 drives the two turntables 3 to rotate towards each other to an inclined state, the two turntables form an inverted "V" shape.
[0020] In this embodiment, the turntable drive assembly 4 includes two cross-arranged rotating arms 41, a drive block 42, and a lifting drive component 43. Each rotating arm 41 connects to a turntable 3, and each rotating arm 41 has an elongated groove 411 within it. A slider 44 is slidably disposed within the groove 411, and the slider 44 is connected to the drive block 42. The lifting drive component 43 drives the drive block 42 to move up and down. The lifting drive component 43 is preferably a cylinder.
[0021] Furthermore, a rotary guide structure is provided between the two rotating arms 41 and / or between one of the rotating arms 41 and the base 1. This rotary guide structure may employ an arc-shaped groove and a guide slider slidably disposed within the arc-shaped groove. In this embodiment, one of the two rotating arms 41 has an arc-shaped groove, and the other is connected to a guide slider; additionally, an arc-shaped groove is provided on the base 1, and a guide slider is connected to the rotating arm 41 closest to the base 1.
[0022] In use, driven by the lifting drive 43, the drive block 42 moves downward, causing the two sliders 44 to move downward together, which in turn causes the two rotating arms 41 to rotate in opposite directions, thereby causing the two turntables 3 to rotate in opposite directions to an inclined state.
[0023] like Fig. 1 and 3As shown, the trimming mechanism 6 includes a movable base 61, which is connected to a first movable module. The first movable module is used to drive the movable base 61 to move along the Z-axis and Y-axis directions. Two slide blocks 62 are slidably connected to the side of the movable base 61 facing the center of the cutting table. A cutting module 63 is rotatably connected to the slide blocks 62. The sliding direction of the slide blocks 62 is parallel to the circuit board support surface of the tilted turntable 3. The cutting module 63 can rotate 90° relative to the slide blocks 62 around the Z-axis direction. In this embodiment, the first movable module includes an electric linear slide table arranged along the Y-axis direction and a lifting cylinder mounted on the electric linear slide table. The slide blocks 62 are connected to an electric linear slide table that drives their movement. The cutting module 63 includes a circular blade and a motor that drives the circular blade to rotate. The cutting module 63 is connected to a servo motor 64 that drives its rotation by 90°.
[0024] After the two turntables 3 rotate to an inclined state, the moving seats 61 of the two trimming mechanisms 6 move downward, so that the circular blades of each cutting module 63 contact the corresponding X-direction circuit board copper foil edge material; each slide 62 moves relative to the moving seat 61, driving the corresponding cutting module 63 to move downward in a direction parallel to the circuit board support surface of the turntable 3, thereby cutting the X-direction circuit board copper foil edge material on the two turntables 3; the moving seat 61 moves upward, so that the circular blades separate from the circuit board; the cutting module 63 is driven to rotate 90°, so that the circular blades are adjusted from the XZ plane to the YZ plane; the moving seat 61 moves downward, so that the circular blades of each cutting module 63 contact the corresponding Y-direction circuit board copper foil edge material; the moving seat 61 moves along the Y-axis direction, driving the corresponding cutting module 63 to move together along the Y-axis direction, thereby cutting the Y-direction circuit board copper foil edge material on the two turntables 3.
[0025] In a preferred embodiment, the Y-direction cutting length of one trimming mechanism 6 is less than half the length of the Y-direction copper foil edge material of the circuit board, while the Y-direction cutting length of the other trimming mechanism 6 is greater than half the length of the Y-direction copper foil edge material of the circuit board. Thus, the two trimming mechanisms 6 can perform trimming simultaneously. The trimming mechanism 6 that completes its trimming operation first moves back to its original position, allowing the other trimming mechanism 6 to continue trimming, thereby cutting off the Y-direction copper foil edge material of the circuit board.
[0026] In this embodiment, the plate-splitting and cutting mechanism 5 includes a laser cutting head 51 and a second moving module that drives the laser cutting head 51 to move along the Y-axis. The second moving module is preferably an electric linear slide. It should be noted that the second moving module and the first moving module can be mounted on the same support frame, as long as there is no interference between them.
[0027] Furthermore, the cutting table 2 is provided with a cutting slit 21 to avoid the laser emitted by the laser cutting head 51, such as... Fig. 2 As shown.
[0028] This utility model discloses a circuit board trimming and slitting device. In use, the circuit board is placed onto a cutting table 2 and two turntables 3. The circuit board is then adsorbed and fixed through vacuum adsorption holes on the two turntables 3. A slitting and cutting mechanism 5 cuts the circuit board into slitting sections. A turntable drive assembly drives the two turntables 3 to rotate together to an inclined state. Two trimming mechanisms 6 first trim the copper foil edges of the two X-axis circuit boards separately, and then jointly trim the copper foil edges of the two Y-axis circuit boards, thus completing the trimming and slitting operations. This circuit board trimming and slitting device, through the cooperation of two trimming mechanisms 6 and two turntables 3, greatly improves trimming efficiency. Furthermore, since the trimming and slitting operations are performed in the same location, there is no need to move the circuit board, resulting in high precision, a compact work cycle, and high efficiency.
[0029] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
