[0021] The following will further describe the technical solution of the utility model in conjunction with the drawings of the embodiments of the utility model, and the utility model is not limited to the following specific implementation methods. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] like Figures 1 to 3 As shown, a servo screw 230 lane changer includes: a mounting frame 100, a driving assembly, a swing arm assembly and a clamping assembly; a first bracket 110 and two second brackets 120 are arranged on the mounting frame 100, a photoelectric detector 111 is arranged on the first bracket 110, and a driven wheel 121 is arranged on each of the second brackets 120; the driving assembly is arranged on the mounting frame 100, the driving assembly is used to drive the swing arm assembly, and the clamping assembly is arranged on the swing arm assembly.

[0023] Specifically, the drive assembly includes a servo motor 210, a coupling 220, a screw rod 230, two first slide rails 240 and two adjusting rods 250. The servo motor 210 is set on the mounting frame 100 through a motor mounting seat 211. The output shaft of the servo motor 210 is connected to the screw rod 230 through the coupling 220. The two first slide rails 240 are spaced apart from the screw rod 230. A slider is slidably arranged on the screw rod 230, and the two adjusting rods 250 are arranged on the slider. The swing arm assembly includes two positioning reference plates 310, two front drive plates 320, two middle drive plates 330 and two rear drive fixing plates 340. Each front drive plate 320 is disposed on one positioning reference plate 310. Each middle drive plate 330 is connected to one end of the front drive plate 320 away from the positioning reference plate 310 through a hinge 350. Each rear drive fixing plate 340 is connected to one end of the middle drive plate 330 away from the front drive plate 320 through a linear bearing assembly 360. One positioning reference plate 310 is disposed at one end of the two adjustment rods 250, and the other positioning reference plate 310 is disposed at the other end of the two adjustment rods 250. Each positioning reference plate 310 is detachably connected to any of the adjustment rods 250. Further, the clamping assembly includes two driving cylinders 410 and two clamping plates 420, each of the driving cylinders 410 is disposed on one of the positioning reference plates 310, and each of the driving cylinders 410 is used to drive one of the clamping plates 420. Two second slide rails 430 are disposed on each of the positioning reference plates 310, one end of each of the clamping plates 420 is slidably disposed on one of the second slide rails 430, and the other end is slidably disposed on another of the second slide rails 430. Each of the positioning reference plates 310 is slidably disposed on two of the first slide rails 240.

[0024] In the above embodiment, two guardrail support rectangular tubes 341 are provided on each rear drive fixing plate 340 , one guardrail support rectangular tube 341 is detachably connected to a guardrail bracket 342 , and the other guardrail support rectangular tube 341 is detachably connected to a fixing seat 343 .

[0025] That is to say, when the servo screw 230 lane changer is used on the conveyor line, the mounting frame 100 is first set on the conveyor line so that the conveyor line can pass through the middle of the mounting frame 100. Furthermore, two guardrail brackets 342 and two fixing seats 343 are set on the mounting plate at one end of the conveyor line, that is, by connecting one guardrail support rectangular tube 341 on each rear drive fixing plate 340 with one guardrail bracket 342, and connecting the other guardrail support rectangular tube 341 with one fixing seat 343, the two rear drive fixing plates 340 can be installed, and after the installation is completed, it can be used.

[0026] When in use, the staff puts down the whole box of products between the two rear drive fixed plates 340, and then transports them along the conveyor line. At this time, under the guidance of the two middle drive plates 330 and the two front drive plates 320, it moves to the middle of the clamping mechanism, and drives a clamping plate 420 through the driving cylinders 410 on both sides, so that each clamping plate 420 moves in the direction of the product and finally abuts the product, that is, the two clamping plates 420 clamp the product from both sides of the product. Then, by starting the servo motor 210, the output shaft of the servo motor 210 rotates to drive the coupling 220 to rotate, and then drives the screw rod 230 to rotate, that is, the slider on the screw rod 230 moves with the rotation of the screw rod 230, and then the two positioning reference plates 310 also move, so that the entire swing arm assembly and the entire clamping assembly can be moved according to specific needs, that is, the product can be moved to the corresponding conveying route on the conveyor line, and then the corresponding clamping plates 420 are driven by the two driving cylinders 410 to no longer abut the product, and the product can continue to be conveyed along the corresponding conveying route. That is to say, the servo motor 210 can control the entire swing arm assembly and the entire clamping assembly to move horizontally above the conveyor line, and because the two rear drive fixed plates 340 are fixed on the mounting plate at one end of the conveyor line, therefore, under the movement of the two middle drive plates 330 and the two front drive plates 320, after the product enters from the middle of the two rear drive fixed plates 340, it can quickly adjust the route following the movement. And because the drive assembly, the swing arm assembly and the clamping assembly are all directly located above the conveyor line, it is not necessary to extend the length of the conveyor line, and it will not cause the overall floor space to increase. By using the servo motor 210 to move the swing arm assembly and the clamping assembly horizontally, it can be well avoided that due to the lateral distance process, if the cylinder is used for driving, the stroke is too large, resulting in the problem of the cylinder being too long. And by using the screw rod 230 for transmission, the overall stability is good.

[0027] In one embodiment, the mounting frame 100 is provided with a dust cover 130, a first fixing plate 140 and a second fixing plate 150, the dust cover 130 covers the top of the mounting frame 100, the servo motor 210 is arranged on the first fixing plate 140, and the screw rod 230 is rotatably arranged on the second fixing plate 150 at one end away from the servo motor 210.

[0028] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
