Description

Technical Field

[0001] This utility model specifically relates to a circuit board production turnover device. Background Technology

[0002] In the circuit board (PCB) manufacturing process, turnover devices are indispensable and crucial equipment, primarily used for the safe and efficient transport and storage of PCBs between different production stages. Currently, most commercially available PCB production turnover devices employ fixed rack structures, with the carriers typically positioned horizontally or at a fixed angle. This fixed structure has several limitations. Firstly, it's difficult to achieve efficient and stable placement and turnover of PCBs of different shapes, such as rectangular and circular boards. For instance, when placing circular PCBs on horizontally positioned carriers, the boards are prone to rolling and shifting, making precise positioning impossible. This not only increases the difficulty for workers but also poses a risk of the boards slipping and being damaged. Conversely, when placing rectangular PCBs on fixed-angle tilted carriers, space may not be fully utilized, and the boards are prone to wobbling after placement, hindering stable transport. Utility Model Content

[0003] In view of the deficiencies of the existing technology, the technical problem to be solved by this utility model is to provide a circuit board production turnover device.

[0004] A circuit board production turnover device includes a support frame and omnidirectional casters located at the four corners of the lower end of the support frame. The support frame has several layers of placement racks for placing PCB boards. Each placement rack includes a first carrier plate and a second carrier plate. Both the first and second carrier plates have corresponding recessed V-shaped grooves for positioning the PCB boards. The first carrier plate is fixedly connected to the support frame. The second carrier plate is located above the first carrier plate and is set at an angle A relative to the first carrier plate. A slider is rotatably arranged at each of the four corners of the second carrier plate. The support frame has movable grooves corresponding to the sliders. The sliders are movably arranged in the movable grooves. The second carrier plate can move along the movable grooves with the sliders so that the angle A is less than or equal to 90 degrees. The support frame is provided with locking members that can lock the displacement of the sliders.

[0005] In one embodiment, the sliders located on the same side of the second carrier plate are slider one and slider two, respectively. The movable grooves are an L-shaped guide groove and a first vertical guide groove. The L-shaped guide groove includes a transverse guide groove and a second vertical guide groove connected to one end of the transverse guide groove. The first vertical guide groove and the second vertical guide groove are located on the same side and are staggered. Slider one is movably disposed in the L-shaped guide groove and can move sequentially along the transverse guide groove and the second vertical guide groove. Slider two is movably disposed in the first vertical guide groove.

[0006] In one embodiment, the locking member includes a locking plate, which is movably disposed on the support frame and can move closer to or further away from the slider two. A plurality of slots are evenly distributed vertically on one side of the locking plate, and a protrusion that can engage with the slots is protruding on one side of the slider two.

[0007] In one embodiment, a through hole is provided on one side of the locking plate, and a screw hole is provided on one side of the support frame corresponding to the through hole. A fastening screw that can cooperate with the screw hole is movably inserted into the through hole. When the fastening screw is tightened and locked in the screw hole, the fastening screw can press the locking plate so that the slot and the protrusion remain in an engaged state.

[0008] In one embodiment, the width direction of the first carrier plate is set at an angle B to the horizontal plane, and the angle B is greater than or equal to 20 degrees and less than or equal to 60 degrees.

[0009] In one embodiment, a clearance cavity is formed between the first carrier plate and the second carrier plate.

[0010] In summary, the advantages of this utility model over the prior art are:

[0011] When angle A is 90 degrees, the second carrier plate is perpendicular to the first carrier plate. At this time, the V-groove structure can provide precise and stable positioning for the rectangular circuit board, which facilitates the placement and turnover of the rectangular circuit board, makes full use of space, and ensures that the circuit board does not shake. When angle B is less than 90 degrees, the second carrier plate and the first carrier plate combine to form a horn-shaped cavity that is narrow inside and wide outside. At this time, the V-groove structure can stably position and clamp the circular circuit board on the upper and lower sides, preventing the circular circuit board from rolling or shifting. This greatly improves the adaptability of the turnover device to circuit boards of different shapes and reduces the placement difficulties and damage risks caused by different circuit board shapes.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 6 The present invention preferably provides a circuit board production turnover device, including a support frame 1 and universal casters 2 disposed at the four corners of the lower end of the support frame 1. The support frame 1 is provided with several layers of placement racks for placing PCB boards. Each placement rack includes a first carrier plate 3 and a second carrier plate 4. Both the first carrier plate 3 and the second carrier plate 4 have a plurality of V-shaped grooves 5 corresponding to each other for positioning the PCB boards. The first carrier plate 3 is fixedly connected to the support frame 1. The second carrier plate 4 is located above the first carrier plate 3 and is set at an angle A relative to the first carrier plate 3. A slider 6 is rotatably disposed at each of the four corners of the second carrier plate 4. The support frame 1 is provided with movable grooves 7 corresponding to the sliders 6. The sliders 6 are movably disposed in the movable grooves 7. The second carrier plate 4 can move along the movable grooves 7 with the sliders 6 so that the angle A is less than or equal to 90 degrees. The support frame 1 is provided with locking members 8 that can lock the displacement of the sliders 6.

[0020] Specifically, when angle A is 90 degrees, the second carrier plate is perpendicular to the first carrier plate. At this time, the V-groove structure can provide precise and stable positioning for the rectangular circuit board, which facilitates the placement and turnover of the rectangular circuit board, makes full use of space, and ensures that the circuit board does not wobble. When angle B is less than 90 degrees, the second carrier plate and the first carrier plate combine to form a horn-shaped cavity that is narrow inside and wide outside. At this time, the V-groove structure can stably position and clamp the circular circuit board on the upper and lower sides, preventing the circular circuit board from rolling or shifting. This greatly improves the adaptability of the turnover device to circuit boards of different shapes and reduces the placement difficulties and damage risks caused by different circuit board shapes.

[0021] Furthermore, the sliders 6 located on the same side of the second carrier plate 4 are slider one 61 and slider two 62, respectively. The movable grooves 7 are an L-shaped guide groove and a first vertical guide groove 71. The L-shaped guide groove includes a transverse guide groove 72 and a second vertical guide groove 73 connected to one end of the transverse guide groove 72. The first vertical guide groove 71 and the second vertical guide groove 73 are located on the same side and are staggered. Slider one 61 is movably disposed in the L-shaped guide groove and can move sequentially along the transverse guide groove 72 and the second vertical guide groove 73. Slider two 62 is movably disposed in the first vertical guide groove 71. Specifically, slider one is movably disposed in the L-shaped guide groove so that it can move sequentially along the transverse guide groove and the second vertical guide groove; slider two is movably disposed in the first vertical guide groove. By moving the sliders in the movable grooves, the tilt angle A of the second carrier plate relative to the first carrier plate can be adjusted, and the tilt angle A can be flexibly adjusted within a range of less than or equal to 90 degrees.

[0022] Furthermore, the locking component 8 includes a locking plate 81, which is movably mounted on the support frame 1 and can move closer to or further away from the second slider 62. A plurality of slots 82 are evenly distributed vertically on one side of the locking plate 81, and a protrusion 83 protrudes from one side of the second slider 62, capable of engaging with the slots 82. Specifically, a plurality of slots are machined vertically on one side of the locking plate, and a protrusion is provided on one side of the second slider. By driving the locking plate to move, the protrusion of the second slider engages with the corresponding slot, thereby locking and fixing the second slider. This locking of the second slider then locks the first slider, thus fixing the second carrier plate relative to the first carrier plate. The locking component can quickly and reliably lock the displacement of the slider, ensuring that the adjusted angle remains stable, meeting the requirements of different production processes for the circuit board placement angle, greatly improving production efficiency and reducing the labor intensity of workers.

[0023] Furthermore, a through hole 84 is provided on one side of the locking plate 81, and a screw hole is provided on one side of the support frame 1 corresponding to the through hole 84. A fastening screw that can cooperate with the screw hole is movably inserted into the through hole 84. When the fastening screw is tightened and locked in the screw hole, the fastening screw can press the locking plate so that the slot 82 and the protrusion 83 remain in an engaged state.

[0024] Specifically, the locking plate in the locking component is connected to the support frame through fastening screws. When the fastening screws are tightened, the locking plate presses against the second slider, causing the slot and the protrusion to fit tightly together. This effectively prevents the second carrier plate from changing angle due to vibration and other factors during transportation and turnover, ensuring the structural stability and reliability of the entire turnover device and ensuring the safety of the circuit board during turnover.

[0025] Furthermore, the width direction of the first carrier plate 3 is set at an angle B to the horizontal plane, and the angle B is greater than or equal to 20 degrees and less than or equal to 60 degrees.

[0026] Specifically, the width direction of the first carrier board is set to an inclination angle B relative to the horizontal plane. The angle of inclination angle B is controlled within the range of greater than or equal to 20 degrees and less than or equal to 60 degrees to ensure that the circuit board can be stably placed in the V-groove of the first and second carrier boards due to its own weight.

[0027] Furthermore, a clearance cavity is formed between the first carrier plate 3 and the second carrier plate 4.
