The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] It is understandable that, referring to Figures 1 to 5The utility model provides a PCB board transfer device, including a base 100, a lifting platform 200 and a lifting mechanism 400. Universal rollers 110 are respectively provided at the four corners of the bottom of the base 100; the lifting platform 200 is arranged above the base 100, and an L-shaped frame 300 is provided on the upper end surface of the lifting platform 200. The L-shaped frame 300 is used to carry the PCB board; the lifting mechanism 400 includes a driving member 410 and two sets of scissor fork assemblies 420. The two sets of scissor fork assemblies 420 are respectively provided on opposite sides of the base 100. The scissor fork assemblies 420 include a driving member 410 and two sets of scissor fork assemblies 420. It includes a first rotating rod 421 and a second rotating rod 422, the first rotating rod 421 and the second rotating rod 422 are arranged crosswise, and the first rotating rod 421 and the second rotating rod 422 are hinged, the upper end of the first rotating rod 421 is hinged to the lifting platform 200, the lower end of the first rotating rod 421 is movably connected to the base 100, the upper end of the second rotating rod 422 is movably connected to the lifting platform 200, and the lower end of the second rotating rod 422 is hinged to the base 100, and the driving member 410 is used to drive the first rotating rod 421 and the second rotating rod 422 to fold or unfold with each other.

[0029] When loading and unloading the PCB board, since the first rotating rod 421 and the second rotating rod 422 are arranged crosswise and the first rotating rod 421 and the second rotating rod 422 are hinged, the first rotating rod 421 and the second rotating rod 422 are driven to rotate around the hinge point by the driving member 410. At the same time, since the upper end of the first rotating rod 421 is hinged to the lifting platform 200, the lower end of the first rotating rod 421 is movably connected to the base 100, the upper end of the second rotating rod 422 is movably connected to the lifting platform 200, and the lower end of the second rotating rod 422 is hinged to the base 100, the first rotating rod 421 is driven to rotate around the hinge point. The lower end of the lifting platform 200 and the upper end of the second rotating rod 422 slide horizontally in the same direction to achieve mutual folding or unfolding movements, thereby driving the lifting platform 200 to move up and down. Since the L-shaped frame 300 is arranged on the upper end surface of the lifting platform 200, it can simultaneously drive the L-shaped frame 300 to move up and down to adjust the height position of the PCB board placed on the L-shaped frame 300, so that the PCB board can be at the same horizontal height position as the work station, thereby facilitating the loading and unloading of the PCB board, improving the transportation efficiency of the PCB board, and reducing the labor intensity of workers.

[0030] At the same time, since universal rollers 110 are respectively provided at the four corners of the bottom of the base 100, the movement and steering of the universal rollers 110 can facilitate the movement of the PCB board transfer device to the corresponding work station, thereby improving the convenience of transfer.

[0031] In addition, since the L-shaped frame 300 is used to carry PCB boards and the L-shaped frame 300 can be removed from the lifting platform 200, it is convenient to carry multiple PCB boards at the same time. The L-shaped frame 300 can be moved to the work station first, and then the PCB boards can be loaded and unloaded one by one to improve the loading and unloading efficiency of the PCB boards.

[0032] It should be noted that, since the two sets of scissor assembly 420 are respectively arranged on the opposite sides of the base 100 , the forces on the opposite sides of the lifting platform 200 are balanced, which can improve the lifting stability of the lifting platform 200 .

[0033] The driving member 410 can drive the first rotating rod 421 and the second rotating rod 422 to fold or unfold relative to each other through the screw-nut mechanism.

[0034] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 4 The base 100 is slidably connected to the first cross bar 423, and the lifting platform 200 is slidably connected to the second cross bar 424. The lower ends of the two first rotating rods 421 are respectively rotatably connected to the two ends of the first cross bar 423, and the upper ends of the two second cross bars 424 are respectively rotatably connected to the two ends of the second cross bar 424. The driving member 410 is fixedly arranged on the base 100, and the first cross bar 423 is connected to the output end of the driving member 410. The driving member 410 is used to drive the first cross bar 423 to move in a horizontal direction close to or away from the second rotating rod 422. Since the lifting platform 200 is slidably connected to the second cross bar 424, the lower ends of the two first rotating rods 421 are respectively rotatably connected to the two ends of the first cross bar 423, and the first cross bar 423 is driven by the driving member 410 to move in the horizontal direction close to or away from the second rotating rod 422, so as to drive the lower end of the first rotating rod 421 to move horizontally, and at the same time, the upper end of the second rotating rod 422 moves horizontally in the same direction, so that the first rotating rod 421 and the second rotating rod 422 are folded or unfolded with each other, thereby driving the lifting platform 200 to move up and down, which can conveniently adjust the height position of the PCB board on the L-shaped frame 300. In addition, by driving the first rotating rods 421 on both sides to move synchronously through the same first cross bar 423, and driving the second rotating rods 422 on both sides to move synchronously through the same second cross bar 424, the movement synchronization of the first rotating rods 421 and the second rotating rod 422 on both sides can be improved, thereby improving the lifting stability of the lifting platform 200.

[0035] It should be noted that the driving member 410 can be a pneumatic cylinder, an oil cylinder or an electric push rod, etc., which can drive the first cross bar 423 to move in the horizontal direction close to or away from the second rotating rod 422.

[0036] Specifically, refer to Figure 1The base 100 is provided with a first horizontal chute 120, to which the first crossbar 423 is slidably connected. The lifting platform 200 is provided with a second horizontal chute 210, to which the second crossbar 424 is slidably connected. The first chute 120 guides the horizontal movement of the first crossbar 423, and the second chute 210 guides the horizontal movement of the second crossbar 424, thereby reducing the possibility of positional deviation and improving the stability of the movement of the first crossbar 423 and the second crossbar 424, thereby improving the stability of the lifting movement of the lifting platform 200.

[0037] It is understandable that, referring to Figures 1 to 3 The lifting platform 200 is rotatably connected to a plurality of rollers 220, which are arranged horizontally and parallel to each other. The rollers 220 are used to support the L-shaped frame 300. Since the lifting platform 200 is rotatably connected to the plurality of rollers 220, which are arranged horizontally and parallel to each other, by placing the L-shaped frame 300 on the rollers 220 and pushing the L-shaped frame 300 to move along the arrangement direction of the rollers 220, the rollers 220 rotate accordingly during movement to reduce the movement resistance of the L-shaped frame 300, thereby facilitating the transfer of the L-shaped frame 300 to the lifting platform 200 and improving the convenience of transferring the L-shaped frame 300.

[0038] It is understandable that Figure 2 、 Figure 3 and Figure 5 The L-shaped frame 300 includes a bottom plate 310 and a back plate 320, which are arranged perpendicular to each other. A baffle 230 is vertically provided on the upper end surface of the lifting platform 200, and the baffle 230 can abut against the back plate 320. The baffle 230 abuts against the back plate 320, which can support the back plate 320, thereby reducing the possibility of the back plate 320 flipping over and causing the PCB to fall, thereby improving the transportation stability of the PCB.

[0039] It should be noted that since the bottom plate 310 and the back plate 320 are arranged perpendicular to each other, when the PCB board is placed on the L-shaped frame 300, the PCB board rests against the back plate 320, causing the back plate 320 to be subjected to force. During the movement of the PCB board transfer device, the back plate 320 is easily flipped due to inertia, causing the PCB board to fall and be damaged. Therefore, supporting the back plate 320 by the baffle 230 can reduce the possibility of the back plate 320 flipping and causing the PCB board to fall.

[0040] An air avoidance groove 311 may be provided on the upper end surface of the base plate 310. Along the length direction of the base plate 310, the air avoidance groove 311 extends from the side of the base plate 310 away from the back plate 320 to the connection between the base plate 310 and the back plate 320, so that workers can reach into the bottom of the PCB board through the air avoidance groove 311 to facilitate the application of force to move the PCB board.

[0041] Specifically, refer to Figure 1 and Figure 3 The lifting platform 200 is provided with two limiting bars 240, which are arranged on opposite sides of the baffle 230. The two limiting bars 240 can respectively abut the two side walls of the bottom plate 310. When the L-shaped frame 300 is moved to the lifting platform 200, the limiting bars 240 on opposite sides abut the two side walls of the bottom plate 310 to guide and limit the L-shaped frame 300, facilitating the positioning of the L-shaped frame 300. In combination with the abutment and limiting action of the baffle 230, the possibility of the L-shaped frame 300 shaking during the movement of the PCB board transfer device can be reduced, thereby improving the stability of the PCB board transfer.

[0042] Specifically, refer to Figure 1 and Figure 3 A guide slope 241 is provided on one end of the limiting strip 240 away from the baffle 230. The guide slopes 241 of the two limiting strips 240 face each other, and the distance between the two guide slopes 241 gradually decreases as they approach the baffle 230. Because the distance between the two guide slopes 241 gradually decreases as they approach the baffle 230, the L-shaped frame 300 can be gradually guided to align and slide into the position between the two limiting strips 240 by sliding along the guide slopes 241, thereby facilitating the positioning of the L-shaped frame 300.

[0043] Specifically, refer to Figures 1 to 3 A limit assembly 250 is provided on the side of the lifting platform 200 away from the baffle 230. The limit assembly 250 includes a fixed seat 251 and a limit rod 252. The fixed seat 251 is fixed to the lifting platform 200, and the limit rod 252 is rotatably connected to the fixed seat 251. The limit rod 252 can abut the side of the bottom plate 310 away from the baffle 230. When the L-shaped frame 300 is placed in a preset position on the lifting platform 200, the limit rod 252 is rotated so that the limit rod 252 abuts the side of the bottom plate 310 away from the baffle 230. In conjunction with the baffle 230 abutting the back plate 320, the position of the L-shaped frame 300 can be determined, thereby reducing the shaking of the L-shaped frame 300 during transportation and improving the stability of the PCB board transportation.

[0044] It is understandable that the limiting components 250 can be provided in two groups, and the two groups of limiting components 250 are respectively arranged on opposite sides of the lifting platform 200, so that the forces on both sides of the L-shaped frame 300 can be balanced to improve the position stability of the L-shaped frame 300.

[0045] Specifically, refer to Figure 1 、 Figure 2 and Figure 5 , first handles 321 are provided on opposite sides of the back plate 320. The first handles 321 provided on opposite sides of the back plate 320 facilitate workers to apply force to carry the L-shaped frame 300, thereby improving the convenience of moving the L-shaped frame 300.

[0046] Specifically, refer to Figures 1 to 3 A second handle 130 is provided on one side of the base 100. The second handle 130 facilitates workers to apply force to push the base 100 to move, thereby improving the convenience of moving the PCB board transfer device.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
