[0040] Figure 1 is the first structural schematic diagram of the servo-driven logistics conveying device provided by an embodiment of this application; Figure 2 is Figure 1 the second structural schematic diagram of the servo-driven logistics conveying device in Figure 3 is Figure 1 the structural schematic diagram of the conveying assembly 200 of the servo-driven logistics conveying device in Figure 4 is Figure 1 the assembly drawing of a partial structure of the servo-driven logistics conveying device in

[0041] Refer to Figure 1 and Figure 2As shown in the figure, an embodiment of the present application provides a servo-driven logistics conveying device, including a frame 100, a conveying component 200, and a servo drive component 300. Among them, the conveying component 200 is arranged on the frame 100, and the conveying component 200 is used to support and drive the movement of goods; the servo drive component 300 includes a servo motor 310 and a transmission component 320. The servo motor 310 can be fixedly installed on the frame 100 through a motor mounting bracket. One end of the transmission component 320 is connected to the servo motor 310, and the other end of the transmission component 320 is connected to the conveying component 200. The servo motor 310 drives the conveying component 200 to act through the transmission component 320, so as to convey goods.

[0042] It can be understood that this device uses the servo motor 310 and the transmission component 320 to drive the conveying component 200 to act, and can control the rotation speed and position of the servo motor 310 through an encoder or other feedback systems. Furthermore, it can accurately regulate the conveying speed and accuracy of the conveying component 200, so that the goods can be accurately conveyed to the designated position. The servo motor 310 has a strong overload capacity and can withstand a large load in a short time, thus ensuring that the logistics conveying device has a greater instantaneous load capacity. In addition, the servo motor 310 has better stability and response characteristics, so as to ensure that the logistics conveying device has better stability and a faster response speed. Finally, compared with the three-phase asynchronous motor in the prior art, the servo motor 310 has a smaller size and weight, has smaller installation space and installation position requirements, is convenient for the assembly and installation of the logistics conveying device, and can reduce the overall size and weight of the device and reduce the manufacturing cost.

[0043] Referring to Figure 1 、 Figure 2 and Figure 4 As shown in the figure, the servo drive component 300 further includes a drive bracket 330. The servo motor 310 is arranged on the frame 100 through the drive bracket 330, and the servo motor 310 is installed on the drive bracket 330 in a cantilever manner. The servo motor 310 has a small size and weight, and is installed on the frame 100 through the drive bracket 330 and the cantilever manner, so as to occupy a small space and is convenient for the staff to install and fix.

[0044] In addition, a drive space is formed between the drive bracket 330 and the frame 100, and the transmission component 320 is arranged in the formed drive space. In order to facilitate the observation and maintenance of the transmission component 320, at least one perspective window 700 is provided in the drive space formed by the drive bracket 330 and the frame 100. Exemplarily, the material of the perspective window 700 can be transparent acrylic.

[0045] Referring to Figure 2As shown, the servo drive assembly 300 further includes a fixing bracket 340. An adjusting screw is provided on the fixing bracket 340. The driving bracket 330 is connected to the frame 100 through a long hole. The adjusting screw is screwed to the fixing bracket 340 and is rotatably connected to the driving bracket 330. Specifically, a long hole is provided on the driving bracket 330. The fixing bolt fixes the driving bracket 330 on the frame 100, and the fixing bolt passes through the long hole. It can be understood that when the fixing bolt is loosened, the driving bracket 330 can be adjusted to move along the length direction of the long hole. In addition, by adjusting the adjusting screw, the driving bracket 330 can be moved along the frame 100, thereby adjusting the position of the servo motor 310 to tension the transmission assembly 320 and avoid failures of the transmission assembly 320. For example, to avoid problems such as slipping or falling off of the transmission parts in the transmission assembly 320.

[0046] As Figure 1 and Figure 2 shown, exemplarily, the frame 100 includes a plurality of cross beams and a plurality of longitudinal beams. The plurality of cross beams and the plurality of longitudinal beams are sequentially connected to form a frame structure, constituting the frame 100. Specifically, the cross beams and the longitudinal beams can be steel profiles.

[0047] Exemplarily, the conveying assembly 200 can be a chain conveying assembly, a synchronous belt conveying assembly, or a roller conveying assembly.

[0048] Referring Figures 1 to 3 to the figure shown, in some examples, the conveying assembly 200 includes a circulating moving assembly 220 and at least two groups of guide wheels 210. At least two guide wheels 210 are arranged on the frame 100 along the length direction of the frame 100. The circulating moving assembly 220 is wound around all the guide wheels 210. The transmission assembly 320 is connected to the circulating moving assembly 220.

[0049] It should be noted that the length direction of the frame 100 can be referred to as the x direction shown in Figure 1 , and the width direction of the frame 100 can be referred to as the y direction shown in Figure 1 . The servo motor 310 transmits power to the circulating moving assembly 220 through the transmission assembly 320, and the circulating moving assembly 220 rotates around a plurality of guide wheels 210. Exemplarily, the conveying assembly 200 includes two groups of guide wheels 210. The two groups of guide wheels 210 are respectively installed at both ends in the length direction of the frame 100 through guide wheel mounting seats. The circulating moving assembly 220 is wound around the two groups of guide wheels 210. The servo motor 310 is connected to the circulating moving assembly 220 through the transmission assembly 320, thereby driving the circulating moving assembly 220 to rotate around the two groups of guide wheels 210.

[0050] Continuing to refer Figures 1 to 3 to the figure shown, there are at least two groups of conveying assemblies 200. At least two groups of conveying assemblies 200 are arranged along the width direction of the frame 100 (which can be referred to asFigure 1 are arranged on the rack 100 at intervals as shown in the y-direction), and two adjacent sets of conveying components 200 are connected by a synchronous shaft 600. The transmission component 320 is connected to at least one of at least two sets of conveying components 200. Exemplarily, the synchronous shaft 600 is arranged along the width direction of the rack 100, and both ends of the synchronous shaft 600 are respectively connected to the circulating movement components 220 in two sets of conveying components 200. The two circulating movement components 220 are respectively connected to both ends of the synchronous shaft 600. During the rotation of the synchronous shaft 600, the two circulating movement components 220 can be driven to rotate simultaneously. The servo motor 310 is fixedly arranged on the rack 100. The servo motor 310 is connected to the synchronous shaft 600 through the transmission component 320. The servo motor 310 drives the two circulating movement components 220 to rotate around the guide wheels 210 simultaneously through the synchronous shaft 600, so as to move the goods placed on the circulating movement components 220. Exemplarily, the transmission component 320 can be a chain transmission component or a belt transmission component, which will not be elaborated here. For example, this logistics conveying device can be used to convey pallets. Specifically, the pallet is placed on the two sets of circulating conveying components 200, and the two sets of circulating conveying components 200 drive the pallet to move during the rotation process.

[0051] In addition, exemparily, the circulating movement component 220 can be configured as a chain movement component, and correspondingly, the guide wheel 210 is configured as a sprocket; in addition, the circulating movement component 220 can be configured as a synchronous belt component, and correspondingly, the guide wheel 210 is configured as a synchronous pulley.

[0052] Referring to Figure 1 As shown, the logistics conveying device further includes a support plate 500. The support plate 500 is arranged on the rack 100 and is located below the upper turning surface of the circulating movement component 220. The support plate 500 is used to support the upper turning surface of the circulating movement component 220. In some examples, the logistics conveying device is provided with at least two support plates 500. The at least two support plates 500 are respectively fixedly connected to the rack 100, and all the support plates 500 are respectively located below the upper turning surfaces of all the circulating movement components 220, and are used to support the upper turning surfaces of the circulating movement components 220. That is to say, each support plate 500 is located between the upper turning surface and the lower turning surface of the corresponding circulating movement component 220, and is used to support the upper turning surface to prevent it from sagging excessively due to its own gravity and the pressure of the goods and interfering with the rack.

[0053] Referring to Figure 3 and Figure 4As shown, the transmission assembly 320 includes a first transmission wheel 321 and a transmission chain 322. The first transmission wheel 321 is arranged on the output shaft of the servo motor 310. One end of the transmission chain 322 is connected to the first transmission wheel 321, and the other end of the transmission chain 322 is connected to the conveying assembly 200. Specifically, one end of the transmission chain 322 is connected to the first transmission wheel 321, and the other end of the transmission chain 322 can be connected to the synchronizing shaft 600 connecting two sets of circulating moving assemblies 220, or can be connected to the guide wheel 210 located at one end of the frame 100. That is to say, the power output by the servo motor 310 is transmitted to the circulating moving assembly 220 through the first transmission wheel 321 and the transmission chain 322, causing the circulating moving assembly 220 to rotate around the guide wheel 210.

[0054] Referring to Figure 3 and Figure 4 As shown, the conveying assembly 200 further includes a tensioning assembly 230 for adjusting the tension degree of the circulating moving assembly 220. Exemplarily, the tensioning assembly 230 includes a tensioning wheel 231, a mounting seat 232 and a fixing plate 233. The fixing plate 233 is connected to the frame 100. The tensioning wheel 231 is rotatably connected to the mounting seat 232. The mounting seat 232 is connected to the fixing plate 233, and the mounting seat 232 selectively moves along the fixing plate 233 so that the tensioning wheel 231 abuts against the circulating moving assembly 220, thereby tensioning the circulating moving assembly 220 to prevent it from falling off the guide wheel 210 due to slack. Specifically, the fixing plate 233 is fixedly installed on the side of the frame 100. The tensioning wheel 231 is arranged on the mounting seat 232 through a rotating shaft. A horizontally arranged waist-shaped groove is formed in the fixing plate 233, and the mounting seat 232 is slidably arranged in the waist-shaped groove. It can be understood that the mounting seat 232 moves in the waist-shaped groove, so that the position of the mounting seat 232 can be adjusted, and further the pressing strength of the tensioning wheel 231 on the circulating moving assembly 220 can be adjusted, and the tightness degree of the circulating moving assembly 220 can be adjusted.

[0055] In some examples, there are at least two tensioning wheels 231 and mounting seats 232. The tensioning wheels 231 and the mounting seats 232 are in one-to-one correspondence, and at least two tensioning wheels 231 are arranged oppositely. Such as Figure 3 and Figure 4As shown, in an embodiment, the tensioning assembly 230 includes two tensioning wheels 231 and two mounting seats 232. The tensioning wheels 231 and the mounting seats 232 are in one-to-one correspondence, and the tensioning wheels 231 are relatively arranged on the fixing plate 233. The chain or synchronous belt in the circulating movement assembly 220 sequentially bypasses one tensioning wheel 231, the driving wheel on the synchronous shaft 600, and the other tensioning wheel 231. When it is necessary to tension the circulating movement assembly 220, the two tensioning wheels 231 can be moved towards each other. In addition, by adjusting the tension of the circulating movement assembly 220 through the two tensioning wheels 231, it can also ensure that the circulating movement assembly 220 has a large wrapping angle with respect to the sprocket (or synchronous pulley) on the synchronous shaft 600, thereby avoiding relative sliding between the sprocket (or synchronous pulley) and the circulating movement assembly 220.

[0057] Referring to Figure 5 and Figure 6 As shown, in some examples, the conveying assembly 200 is a roller conveying assembly, which includes a plurality of rollers 400. The plurality of rollers 400 are arranged at intervals along the length direction of the frame 100. Adjacent two rollers 400 are connected by a connecting member, and the transmission assembly 320 is connected to at least one roller 400. Exemplarily, a sprocket is installed at the end of each roller 400, and adjacent two rollers 400 are connected by a transmission chain. At the same time, the servo motor 310 fixed on the frame 100 is connected to at least one roller 400 through the transmission chain 322, so that the servo motor 310 can drive all the rollers 400 to rotate synchronously to convey goods.
