[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0025] like Figure 1 and Figure 6 As shown, the double-station multi-specification circuit board loading equipment provided by the present invention includes a frame 100, two lifting assemblies 200, a transmission line 300 and two material moving assemblies 400. The two lifting assemblies 200 are fixedly connected to the frame 100 and each has a lifting end. The transmission line 300 includes two fixed plates 310, a movable plate 320, two belts 330 and a plurality of adjusting screws 340. The two fixed plates 310 are parallel to each other and fixedly arranged on the frame 100. The movable plate 320 is arranged between the two fixed plates 310 and is arranged parallel to the fixed plates 310. The two belts 330 is installed at the top position of one of the fixed plates 310 and the movable plate 320 on the opposite side. Multiple adjusting screws 340 are arranged in parallel and pass through one of the fixed plates 310, the movable plate 320 and the other fixed plate 310 in sequence. Multiple adjusting screws 340 are rotatably connected to the two fixed plates 310. Multiple adjusting screws 340 are connected to the threaded holes opened on the movable plate 320. Two material moving assemblies 400 are arranged in sequence along the conveying direction of the transmission line 300. Both material moving assemblies 400 have a material moving end for transferring the PCB board on the corresponding lifting end to the two belts 330.

[0026] During implementation, two circuit boards can be placed on the lifting ends of the two lifting assemblies 200 at one time. After the lifting assembly 200 drives the circuit boards to move to a predetermined height, the two material moving assemblies 400 can synchronously grab the two circuit boards onto the transmission line 300, thereby improving the loading efficiency. At the same time, by rotating the adjusting screw 340, the movable plate 320 can move between the two fixed plates 310, thereby adjusting the distance between the two belts 330 to accommodate circuit boards of different specifications.

[0027] The rack 100 in this embodiment is the frame structure shown in the figure, which provides support for the installation of other components and will not be elaborated on in detail here.

[0028] The lifting component 200 in this embodiment vertically moves the circuit board to a position close to the material moving component 400, pushes the circuit board trolley to a position close to the lifting component 200, and continuously places the circuit board on the lifting end to complete the feeding process.

[0029] like Figure 2 As shown, each lifting assembly 200 in this embodiment includes a vertical plate 210, an adjustment plate 221 and a lifting member 230. The bottom of the vertical plate 210 is fixedly connected to the frame 100, the bottom of the adjustment plate 221 is slidingly connected to the frame 100 and is arranged parallel to the vertical plate 210, and the lifting end of the lifting member 230 is located between the vertical plate 210 and the adjustment plate 221.

[0030] It is understandable that by moving the adjustment plate 221, the distance between the adjustment plate 221 and the vertical plate 210 can be adapted to the width of the circuit board, thereby preventing the circuit board from falling and being damaged during the upward movement.

[0031] In one embodiment, the lifting member 230 includes a motor 231, a lifting screw 232 and a load-bearing frame 233. The motor 231 is fixedly mounted on the frame 100, and the output end of the motor 231 is connected to the lifting screw 232. The lifting screw 232 is arranged on the side of the adjustment plate 221 away from the vertical plate 210 and is rotatably connected to the frame 100. The load-bearing frame 233 is slidably connected to the frame 100 in the vertical direction via the column. One side of the load-bearing frame 233 is cooperatively connected to the lifting screw 232, and the other side of the load-bearing frame 233 extends to a position between the vertical plate 210 and the adjustment plate 221.

[0032] It is understandable that the output end of the motor 231 can be connected to the lifting screw 232 through structures such as a conveyor belt and gears.

[0033] In order to facilitate the knowledge of whether a circuit board is placed on the load-bearing frame 233 and the vertical position of the load-bearing frame 233, the lifting member 230 also includes a load-bearing plate 233a, a sheet material sensor 233b, a connecting block 233c and a plurality of displacement sensors 233d. The load-bearing plate 233a is arranged at a position between the vertical plate 210 and the adjustment plate 221. The load-bearing plate 233a is fixedly set on the top of the load-bearing frame 233. The sheet material sensor is set at a position between the load-bearing plate 233a and the load-bearing frame 233. The sensing end of the sheet material sensor extends to the top of the load-bearing plate 233a. The connecting block 233c is connected to the load-bearing frame 233. Multiple displacement sensors 233d are arranged in sequence on the frame 100 along the vertical direction. The detection ends of the multiple displacement sensors 233d point to the moving path setting of the connecting block 233c.

[0034] The sheet material sensor 233b may be implemented by a contact switch, and the displacement sensor 233d may be implemented by an infrared sensor.

[0035] When the supporting plate raises the circuit board to the highest position, the horizontal position of the circuit board needs to be limited so that the material moving assembly 400 can just grab the circuit board onto the two belts 330. Figure 3-4 As shown, the lifting assembly 200 also includes a positioning member 240, which includes a first pushing cylinder 241, a baffle 242 and a second pushing cylinder 243. The first pushing cylinder 241 is arranged on the top of the adjusting plate 221, and the output end of the first pushing cylinder 241 is directed to the vertical plate 210. The baffle 242 is vertically arranged and connected to the side of the vertical plate 210 in a direction perpendicular to the vertical plate 210. The second pushing cylinder 243 is arranged on the frame 100, and the output end of the second pushing cylinder 243 is directed to the baffle 242.

[0036] like Figure 5 As shown, to facilitate placement of the circuit board on the load-bearing plate 233a, this embodiment further includes a plurality of smooth bars 250 disposed on the side of the lifting assembly 200 away from the frame 100. Every two smooth bars 250 are disposed directly opposite the space between the vertical plate 210 and the adjustment plate 221. The smooth bars 250 include a support frame 251 and a plurality of rollers 252. The rotation axes of the plurality of rollers 252 are all arranged parallel to the movement direction of the adjustment plate 221. The plurality of rollers 252 are rotatably connected to the top of the support frame 251, and the tops of the plurality of rollers 252 form a guide surface.

[0037] In order to lock the adjustment plate 221 in the current position and prevent the adjustment plate 221 from moving during the upward movement of the circuit board, this embodiment also includes two locking screws and a slide rail 222. The top of each adjustment plate 221 is slidably connected to the rack 100 via the slide rail 222. Each adjustment plate 221 is connected to a locking screw, and the free end of the locking screw passes through the adjustment plate 221 and can abut against the rack 100.

[0038] The conveyor line in this embodiment includes two fixed plates 310, a movable plate 320, two belts 330 and a plurality of adjusting screws 340. The two fixed plates 310 are parallel to each other and fixedly arranged on the frame 100. The movable plate 320 is arranged between the two fixed plates 310 and parallel to the fixed plates 310. The two belts 330 are installed at the top position on the opposite side of one of the fixed plates 310 and the movable plate 320. The plurality of adjusting screws 340 are arranged in parallel and pass through one of the fixed plates 310, the movable plate 320 and the other fixed plate 310 in sequence. The plurality of adjusting screws 340 are all rotatably connected to the two fixed plates 310, and the plurality of adjusting screws 340 are connected to the threaded holes opened on the movable plate 320.

[0039] By rotating the adjusting screw 340, the gap between the two belts 330 can be controlled, so that circuit boards of various specifications can be adapted. It can be understood that the above-mentioned belts 330 are thinner conveyor belts, and the two belts 330 are in contact with the bottom of both sides of the circuit board for conveying the circuit board.

[0040] Considering that the transmission line 300 may be set to be longer, for this reason, the number of movable plates 320 in this embodiment is multiple, and the multiple movable plates 320 are arranged in sequence along the length direction thereof. The number of fixed plates 310 located on both sides of the movable plate 320 is multiple and corresponds one to one. Each movable plate 320 is provided with two adjusting screws 340. The transmission line 300 also includes multiple handles 341 corresponding one to one to the multiple movable plates 320, and the multiple handles 341 are all connected to one end of the screw on the corresponding movable plate 320.

[0041] The material moving assembly 400 in this embodiment is a structure for grabbing a circuit board and moving it.

[0042] like Figure 5 Shown, in one embodiment, two material shifting assemblies 400 all comprise the first moving member 410, the second moving member 420, the 3rd moving member 430, a connecting frame 440 and a plurality of suction nozzles 450, the first moving member 410 is installed on the frame 100, the output terminal of the first moving member 410 is connected with the second moving member 420, in order to drive the second moving member 420 to move along the connection direction of its corresponding lifting assembly 200 and transmission line 300, the output terminal of the second moving member 420 is connected with the 3rd moving member 430, in order to drive the 3rd moving member 430 to move along the conveying direction parallel to the transmission line 300, the output terminal of the 3rd moving member 430 is connected with the connecting frame 440, in order to drive the connecting frame 440 to move along the vertical direction, a plurality of suction nozzles 450 are all installed on the connecting frame 440, the top of a plurality of suction nozzles 450 is used to connect an air source, and a plurality of suction nozzles 450 the bottom forms a material shifting end.Wherein, the top of suction nozzle 450 can be connected to a vacuum pump, by negative pressure adsorption circuit board.

[0043] The first moving member 410 and the second moving member 420 may be implemented by a servo motor + lead screw structure, and the third moving member 430 may be implemented by a cylinder.

[0044] Compared with the existing technology: two circuit boards can be placed on the lifting ends of the two lifting assemblies 200 at one time. After the lifting assembly 200 drives the circuit boards to move to a predetermined height, the two material moving assemblies 400 can synchronously grab the two circuit boards onto the transmission line 300, thereby improving the loading efficiency. At the same time, by rotating the adjusting screw 340, the movable plate 320 can move between the two fixed plates 310, thereby adjusting the distance between the two belts 330 to adapt to circuit boards of different specifications.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
