Description

Technical Field

[0001] This utility model relates to the field of PCB motherboard technology, and in particular to a transfer device for PCB motherboard production. Background Technology

[0002] A PCB motherboard, or printed circuit board, is one of the core components of electronic devices. As the mounting and connecting medium for various electronic components, it plays a crucial role in electronic equipment. The PCB motherboard manufacturing process involves multiple precision steps, including etching, drilling, surface mounting, soldering, and testing, and the motherboard must be transferred between these processes. Because the circuitry and components on the motherboard surface are extremely delicate and fragile, even slight vibrations, collisions, or friction can cause scratches on the circuitry or component detachment, affecting product yield. Therefore, specialized transfer devices for production are indispensable key equipment.

[0003] Currently, in related technologies, PCB motherboard production transfer carts have become an important part of logistics transfer within production workshops due to their flexible mobility and batch carrying capacity. These transfer carts typically use metal frames equipped with casters and braking devices at the bottom. The carrying platform on the metal frame is usually made of anti-static composite board material, manufactured using a one-piece molding process, with a uniformly laid flexible cushioning layer of appropriate thickness on the surface to ensure the positional stability and surface protection of the motherboards during transfer. Furthermore, some transfer carts are equipped with detachable layered partitions. By manually removing or adjusting the partition spacing and extending the side baffle length, they can accommodate PCB motherboards of different thicknesses and widths. However, once the layered partitions are fixed, access to the middle and lower layers of PCB motherboards is easily restricted by space, increasing operational complexity. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a transfer device for PCB motherboard production, which can conveniently adjust the height of the carrier board to adapt to the transfer space requirements of PCB motherboards of different specifications. At the same time, through the locking component and the first card block engaging, the carrier board can be adjusted to a pick-up and put-down angle that conforms to the operating habits of the staff or meets the on-site operating space requirements, thereby improving the convenience of PCB motherboard pick-up and put-down operations and reducing the risk of PCB motherboard corners being bumped during the pick-up and put-down process.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a transfer device for PCB motherboard production, comprising: a base plate, casters, two uprights, and a carrying mechanism, wherein the casters are disposed at the bottom end of the base plate; the two uprights are symmetrically disposed on the upper surface of the base plate, and each upright is provided with a vertical rod; the carrying mechanism includes two adjusting components, a crossbar, multiple load plates, and multiple sets of locking components, wherein the two adjusting components are respectively disposed on the corresponding vertical rods; the crossbar is disposed between the two uprights, and both ends of the crossbar are respectively connected to the corresponding adjusting components; the multiple sets of load plates are equally spaced on the crossbar, and first locking blocks are provided on the side walls of the load plates; the multiple sets of locking components are respectively disposed at both ends of the corresponding load plates, and the locking components are nested on the crossbar, and the locking components engage with the first locking blocks on the side walls of the load plates to limit the movement of the load plates.

[0008] Specifically, the carrier plate is configured in an L-shape, and multiple grooves are evenly spaced on the carrier plate, with insert rods provided on both sides of the grooves.

[0009] Specifically, the adjustment assembly includes a movable component, an arc-shaped connector, a plug-in rod, a first abutment plate, a second abutment plate, and a locking cam. The movable component is movably connected to the upright and connected to the crossbar. Two arc-shaped connectors are symmetrically arranged on the sidewalls of the movable component, and each arc-shaped connector has a plug hole. The plug-in rod passes through the plug hole, with both ends extending through the two arc-shaped connectors. The first and second abutment plates are symmetrically arranged at the two extended ends of the plug-in rod, and corresponding compression springs are provided on the sidewalls of the first and second abutment plates. The compression springs are sleeved on the plug-in rod, and the other end of the compression spring abuts against the arc-shaped connector. The locking cam is movably connected to the plug-in rod, and the locking cam is in contact with the second abutment plate.

[0010] Specifically, the locking assembly includes a fixed plate, an auxiliary spring, and a limiting plate. The fixed plate is disposed on the crossbar; the auxiliary spring is sleeved on the crossbar, and one end of the auxiliary spring is connected to the fixed plate; the limiting plate is movably connected to the crossbar, and the limiting plate is connected to the other end of the auxiliary spring, and a second locking block is provided on the limiting plate.

[0011] Specifically, the second card block corresponds to the first card block, and multiple second card blocks and first card blocks are arranged in a circular array about the center point of the limiting plate.

At the same time, by releasing the locking component from the first locking block, the carrier plate can be rotated to adjust the carrier plate to a pick-up and put-down angle that conforms to the operating habits of the staff or meets the requirements of the on-site operating space. Then, by re-locking the locking component with the first locking block at the corresponding position, the angle is fixed, which improves the convenience of PCB motherboard pick-up and put-down operations and reduces the risk of PCB motherboard corners being bumped during the pick-up and put-down process.

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes a PCB motherboard manufacturing transfer device according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown in the figure, a transfer device for PCB motherboard production according to an embodiment of the present invention may include a base plate 1, casters 2, two uprights 3 and a load-bearing mechanism 4.

[0023] Among them, the casters 2 are set at the bottom of the base plate 1, and the two uprights 3 are symmetrically arranged on the upper surface of the base plate 1, and each upright is provided with a vertical rod 31.

[0024] It should be noted that the universal wheels 2 described in this embodiment are provided with four wheels, which are respectively located at the four corners of the bottom of the base plate 1, so as to facilitate the flexible movement and turning of the device.

[0025] The supporting mechanism 4 includes two adjusting components 41, a crossbar 42, multiple load plates 43, and multiple sets of locking components 44. The two adjusting components 41 are respectively mounted on the corresponding vertical bars 31. The crossbar 42 is mounted between the two uprights 3, and both ends of the crossbar 42 are connected to the corresponding adjusting components 41. The multiple sets of load plates 43 are evenly spaced on the crossbar 42, and first locking blocks 431 are provided on both sides of the load plates 43. The multiple sets of locking components 44 are respectively mounted on both ends of the corresponding load plates 43, and the locking components 44 are nested on the crossbar 42. The locking components 44 engage with the first locking blocks 431 on the side walls of the load plates 43 to limit the movement of the load plates 43.

[0026] It should be noted that the adjustment component 41 described in this embodiment has a locking structure. Through the locking structure, the adjustment component 41 can be fixed at any height position of the vertical rod 31, thereby realizing the adjustment of the overall height of the horizontal rod 42 and the carrier plate 43 to adapt to the transportation needs of PCB motherboards of different sizes.

[0027] Specifically, the entire device can be flexibly moved to the PCB motherboard transfer station by the rolling action of the casters 2 at the bottom of the base plate 1. Then, according to the specifications and dimensions of the PCB motherboard to be transferred, the operator operates the locking structure of the adjusting component 41 to release its fixed state with the vertical rod 31, thereby controlling the adjusting component 41 to slide up and down. After moving the adjusting component 41 to the target height, it is then locked again. At the same time, the adjusting component 41 will drive the horizontal rod 42 and multiple sets of carrier plates 43 to adjust synchronously, so that the carrier plates 43 move to the bearing height adapted to the motherboard. Then, the PCB motherboard can be placed stably on the surface of the carrier plate 43.

[0028] Furthermore, when it is necessary to adjust the angle of the carrier plate 43 according to the ease of handling or the form of the motherboard, the locking component 44 can be operated to release its engagement with the first latch 431 on the side wall of the carrier plate 43, thereby releasing the limiting constraint on the carrier plate 43. Then, the carrier plate 43 can be rotated to adjust to the required angle. After the adjustment is completed, the locking component 44 can be engaged and locked with the first latch 431 in the corresponding position to fix the angle of the carrier plate 43, preventing it from shifting in angle or position due to vibration during transportation, and ensuring the stability of the PCB motherboard transportation.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, the loading plate 43 is L-shaped, and multiple grooves 432 are evenly spaced on the loading plate 43. Insert rods 433 are provided on the loading plate 43 on both sides of the grooves 432.

[0030] It should be noted that the groove 432 described in this embodiment can be adapted to the edge contour of the PCB motherboard, which facilitates the quick positioning and placement of motherboards of different sizes. At the same time, the inserts 433 on both sides of the groove 432 can further protect the edge of the motherboard, preventing damage to the corners of the motherboard due to vibration or slight collision during transportation, thereby improving the safety and reliability of the transportation process.

[0031] Specifically, staff can insert the edge of the PCB motherboard into the corresponding groove 432 on the carrier plate 43 according to the edge contour of the motherboard to be transported, so as to achieve quick positioning of the motherboard and avoid displacement during placement. At the same time, in the L-shaped structure of the carrier plate 43, the vertical side abuts against the side of the motherboard to form a limit and prevent the motherboard from shifting during the transport process.

[0032] In one embodiment of this utility model, such as Figure 2As shown, the adjustment assembly 41 includes a movable member 411, an arc-shaped connector 412, a plug rod 413, a first abutment plate 414, a second abutment plate 415, and a locking cam 416. The movable member 411 is movably connected to the upright 3 and is connected to the crossbar 42. Two arc-shaped connectors 412 are symmetrically arranged on the sidewall of the movable member 411, and each arc-shaped connector 412 has a plug hole 4121. The plug rod 413 passes through the plug hole 4121. Two arc-shaped connectors 412 extend through both ends of the plug rod 413. The first abutment plate 414 and the second abutment plate 415 are symmetrically arranged at the two protruding ends of the plug rod 413. The first abutment plate 414 and the second abutment plate 415 are respectively provided with corresponding compression springs 5 ​​on their side walls. The compression springs 5 ​​are sleeved on the plug rod 413, and the other end of the compression springs 5 ​​abuts against the arc-shaped connectors 412. The locking cam 416 is movably connected to the plug rod 413, and the locking cam 416 is in contact with the second abutment plate 415.

[0033] It should be noted that the inner arc of the arc-shaped connector 412 described in this embodiment is adapted to the outer periphery of the vertical rod 31 to ensure the stability of the arc-shaped connector 412 when it moves up and down.

[0034] Additionally, it should be noted that the first contact plate 414 described in this embodiment is threadedly connected to the plug rod 413, and the first contact plate 414 and the plug rod 413 are detachably connected by thread engagement.

[0035] Specifically, when assembling the adjustment component 41, the threaded section of the plug rod 413 is first inserted through the insertion holes 4121 of the two arc-shaped connectors 412 in sequence. Then, the first contact plate 414 is screwed into the threaded section of the plug rod 413. At this time, the compression spring 5 sleeved on the plug rod 413 is in a preset pre-compression state. Under the action of the spring force, the first contact plate 414 and the second contact plate 415 form initial contact with the outer wall of the vertical rod 31, realizing the initial limitation of the free sliding of the moving part 411. Then, the locking cam 416 is rotated so that its protruding end presses the second contact plate 415, completing the initial fixation of the adjustment component 41.

[0036] When the height of the crossbar 42 needs to be adjusted, first rotate the locking cam 416 so that its protruding end moves away from the second abutment plate 415. At this time, the squeezing force of the compression spring 5 is weakened, which reduces the squeezing force of the first abutment plate 414 and the second abutment plate 415 on the vertical bar 31. The operator can push the moving part 411 to slide up and down along the vertical bar 31 until the crossbar 42 drives the carrying plate 43 to the target height. After the height is determined, rotate the locking cam 416 in the opposite direction so that its protruding end squeezes the second abutment plate 415 again, and transmits the squeezing force to the first abutment plate 414 through the plug rod 413. The compression spring 5 is further compressed, thereby clamping the vertical bar 31 and locking the adjustment component 41, thus completing the height adjustment of the carrying plate 43.

[0037] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the locking assembly 44 includes a fixed plate 441, an auxiliary spring 442, and a limiting plate 443. The fixed plate 441 is disposed on the crossbar 42, the auxiliary spring 442 is sleeved on the crossbar 42, and one end of the auxiliary spring 442 is connected to the fixed plate 441. The limiting plate 443 is movably connected to the crossbar 42, and the other end of the limiting plate 443 is connected to the auxiliary spring 442. A second locking block 4431 is provided on the limiting plate 443.

[0038] It should be noted that the limiting plate 443 described in this embodiment can slide along the axial direction of the crossbar 42, and the second locking block 4431 on the side wall of the limiting plate 443 matches the structure of the first locking block 431 on the side wall of the carrying plate 43 to form a locking engagement.

[0039] Additionally, it should be noted that the limiting plate 443 described in this embodiment is provided with protrusions, and the outer wall of the carrying plate 43 is provided with corresponding locking blocks that are adapted to the protrusions. When the carrying plate 43 is rotated to adjust the angle, the protrusions remain fixed with the limiting plate 443, and the locking blocks rotate synchronously with the carrying plate 43. When the carrying plate 43 rotates to a preset angle range, the locking blocks abut against the protrusions, thereby restricting the carrying plate 43 from continuing to rotate, preventing its rotation angle from being too large and causing the PCB motherboard to be unstable, and ensuring the stable placement of the PCB motherboard during the transfer process.

[0040] Specifically, in the initial state, the auxiliary spring 442 is in a pre-compressed state, so that under the elastic force of the auxiliary spring 442, the limiting plate 443 is pushed to slide along the crossbar 42 axially toward the carrier plate 43, so that the second locking block 4431 on the limiting plate 443 is tightly engaged with the first locking block 431 on the carrier plate 43, thereby restricting the carrier plate 43.

[0041] When it is necessary to adjust the angle of the loading plate 43, the limiting plate 443 is pulled away from the loading plate 43, causing the limiting plate 443 to slide along the crossbar 42 and compress the auxiliary spring 442. This causes the second locking block 4431 to separate from the first locking block 431, releasing the limiting constraint on the loading plate 43. Then, the loading plate 43 is rotated. When it is rotated to the preset angle, the limiting plate 443 is released, so that the limiting plate 443, under the elastic force of the auxiliary spring 442, causes the second locking block 4431 to engage with the first locking block 431 again, thus achieving a stable lock on the angle of the loading plate 43.

[0042] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the second card block 4431 corresponds to the first card block 431, and the second card block 4431 and the first card block 431 are arranged in a circular array about the center point of the limiting plate 443.

[0043] It should be noted that the multiple second locking blocks 4431 and multiple first locking blocks 431 described in this embodiment can make the card receive force evenly. During rotation adjustment, the first locking blocks 431 and the second locking blocks 4431 at different positions can engage and cooperate to achieve multi-angle locking and extend service life.

[0044] Specifically, by engaging the second locking block 4431 with the first locking block 431 at the corresponding position, the carrier plate 43 is kept at a preset angle, thus achieving a stable lock.

[0045] In summary, the PCB motherboard production transfer device of this utility model can move the carrier plate up and down along the vertical rod to a suitable height by adjusting the cooperation between the adjusting component and the vertical rod, thereby adapting to the transfer space requirements of PCB motherboards of different specifications. Simultaneously, by releasing the locking component from the first locking block, the carrier plate can be rotated to adjust it to a pick-and-place angle that conforms to the operator's operating habits or meets the on-site operating space requirements. Then, by re-engaging the locking component with the corresponding first locking block, the angle is fixed, improving the convenience of PCB motherboard pick-and-place operations and reducing the risk of PCB motherboard corner damage during the process.
