[0033] Please see Figure 1 This embodiment provides an automated belt sander, which includes: a base 100, two parallel multi-station belt sanding mechanisms 200, and a robot arm 300. The two multi-station belt sanding mechanisms 200 are both disposed on the base 100, and the robot arm 300 is movably disposed. The robot arm 300 is used to clamp the workpiece so as to polish the workpiece on the two multi-station belt sanding mechanisms 200 respectively.
[0034] Please see Figure 2 The multi-station sanding belt mechanism 200 includes a main body 211, a first sanding belt 212, a plurality of contact wheels 213, and a plurality of guide wheels 214. The main body 211 is provided with contact wheels 213 and guide wheels 214. The first sanding belt 212 is wound around the contact wheels 213 and guide wheels 214. The plurality of contact wheels 213 are arranged in a straight line. The plurality of guide wheels 214 are spaced apart from the plurality of contact wheels 213, so that the first sanding belt 212 forms a plurality of V-shaped grinding platforms 224 arranged in a straight line on the plurality of contact wheels 213.
[0035] In this embodiment, two parallel multi-station belt abrasive mechanisms 200 are provided on the base 100. The multi-station belt abrasive mechanisms 200 are used to polish the workpiece. During the polishing process, the robot arm 300 can hold the workpiece in one of the multi-station belt abrasive mechanisms 200 for rough grinding and polishing. Afterward, the robot arm 300 can move the workpiece to the other multi-station belt abrasive mechanism 200 for fine grinding and polishing. Compared with the prior art (e.g., loading the workpiece onto the rough grinding and polishing equipment, unloading it after rough grinding and polishing, transferring it to the fine grinding and polishing equipment, and then loading it onto the fine grinding and polishing equipment and unloading it after fine grinding and polishing), this can avoid repeated loading and unloading, save time for changing equipment, and improve work efficiency.
[0036] It is understandable that the multi-station belt sander 200 refers to a machine with multiple polishing stations. The multi-station belt sander 200 can polish multiple workpieces at the same time, which can further improve work efficiency. For example, the multi-station sanding belt mechanism 200 includes a main body 211, a first sanding belt 212, several contact wheels 213, and several guide wheels 214. The guide wheels 214 and contact wheels 213 are spaced apart. The first sanding belt 212 is wound around the contact wheels 213 and guide wheels 214, and the first sanding belt 212 is arranged in an "S" shape, that is, the contact wheels 213 cause the first sanding belt 212 to protrude outward, and the guide wheels 214 cause the first sanding belt 212 to be recessed inward. Thus, one contact wheel 213 causes the first sanding belt 212 to form an outwardly protruding V-shaped grinding platform 224, and several contact wheels 213 cause the first sanding belt 212 to form several outwardly protruding V-shaped grinding platforms 224. Several outwardly protruding V-shaped grinding platforms 224 can process several workpieces simultaneously, thus further improving the polishing efficiency of the workpieces.
[0037] During the polishing process, the workpiece abuts against the V-shaped grinding platform 224. Specifically, the workpiece abuts against the contact wheel 213 via the first abrasive belt 212.
[0038] The robot arm 300 can hold multiple workpieces at the same time. The robot arm 300 can be understood as existing technology, and the specific structure of the robot arm 300 will not be described in detail.
[0039] Specifically, please refer to Figure 3 The multi-station sanding belt mechanism 200 also includes a drive roller 215, a fixed roller 216, a tension roller 217, and a tensioning mechanism 218. The drive roller 215, the fixed roller 216, the tension roller 217, and the tensioning mechanism 218 are all disposed on the main body 211. The drive roller 215, the fixed roller 216, and the tension roller 217 are all connected to the first sanding belt 212. The tensioning mechanism 218 is driven to the tension roller 217. The tensioning mechanism 218 is used to drive the tension roller 217 to move in order to adjust the tension of the first sanding belt 212.
[0040] In this embodiment, the drive roller 215 can drive the first abrasive belt 212 to rotate, so that the first abrasive belt 212 polishes multiple workpieces simultaneously. The fixed roller 216 and the tension roller 217 are both connected to the first abrasive belt 212. The fixed roller 216 and the tension roller 217 are both used to tension the first abrasive belt 212. The tensioning mechanism 218 can drive the tension roller 217 to move, so as to adjust the tension of the first abrasive belt 212 and prevent the first abrasive belt 212 from being too loose or too tight.
[0041] Specifically, please refer to Figure 3 The first sanding belt 212 is sequentially connected by a drive roller 215, a fixed roller 216, several contact wheels 213 and a tension roller 217. The fixed roller 216 and the tension roller 217 are approximately symmetrical about left and right relative to the extension lines of the drive roller 215.
[0042] In this embodiment, the drive roller 215, the fixed roller 216, a plurality of contact wheels 213 and the tension roller 217 are arranged in a roughly pentagonal shape. The fixed roller 216 is arranged on one side of the drive roller 215 and the tension roller 217 is arranged on the other side of the drive roller 215. The fixed roller 216 and the tension roller 217 are roughly symmetrical about left and right with respect to the extension line of the drive roller 215. This makes the first sanding belt 212 uniformly stressed and makes the first sanding belt 212 run smoothly.
[0043] Specifically, please refer to Figure 3 The fixed roller 216 and the tension roller 217 are roughly symmetrical about left and right with respect to the center lines of the contact rollers 213.
[0044] In this embodiment, the fixed roller 216 is located on the left side of the plurality of contact wheels 213, and the tension roller 217 is located on the right side of the plurality of contact wheels 213. The fixed roller 216 and the tension roller 217 are approximately symmetrical about the center line of the plurality of contact wheels 213, so that the first sanding belt 212 is subjected to uniform force and the first sanding belt 212 runs smoothly.
[0045] Specifically, please refer to Figure 3 The multi-station sanding belt mechanism 200 also includes a drive motor 219, a drive wheel 220, a driven wheel 221, and a synchronous belt. The drive motor 219 is equipped with a drive shaft, the drive wheel 220 is equipped with a drive shaft, the drive wheel 220 is connected to the driven wheel 221 through the synchronous belt, the driven wheel 221 is equipped with a transmission shaft, and a drive roller 215 is mounted on the transmission shaft.
[0046] In this embodiment, the drive motor 219 can drive the drive wheel 220 to rotate. The drive wheel 220 can drive the driven wheel 221 to rotate via a synchronous belt. The driven wheel 221 drives the drive roller 215 to rotate via a transmission shaft. The synchronous belt transmission has high precision and good synchronization, which can enable the drive motor 219 to precisely control the operation of the driven wheel 221, so that the driven wheel 221 has no slippage transmission, high efficiency and energy saving, compact structure, space saving, low noise and low vibration.
[0047] Specifically, please refer to Figure 2 Several contact wheels 213 are arranged at equal intervals. This ensures that the V-shaped grinding platform 224 is also arranged at equal intervals, enabling simultaneous and synchronous processing of multiple workpieces and improving processing efficiency.
[0048] Specifically, please refer to Figure 3 The number of contact wheels 213 in the multi-station sanding belt mechanism 200 is set to 4.
[0049] For example, the multi-station belt sander mechanism 200 has four contact wheels 213, which allows the first sanding belt 212 to form four V-shaped grinding platforms 224. This improves processing efficiency and makes full use of the equipment space. Generally, a conventional belt sander has only one grinding station on its base 100, resulting in low efficiency and a large footprint. It should be understood that the number of polishing wheels is not limited to the four mentioned above; other configurations are possible and are not limited here.
[0050] Specifically, please refer to Figure 1 The first abrasive belt 212 of one multi-station abrasive belt mechanism 200 is configured as a coarse abrasive belt, and the first abrasive belt 212 of the other multi-station abrasive belt mechanism 200 is configured as a fine abrasive belt.
[0051] In this embodiment, the first abrasive belt 212 of one multi-station abrasive belt mechanism 200 is set as a coarse abrasive belt, and the first abrasive belt 212 of the other multi-station abrasive belt mechanism 200 is set as a fine abrasive belt. In this way, the robot arm 300 can clamp the workpiece and perform coarse grinding and polishing in one of the multi-station abrasive belt mechanisms 200. Afterward, the robot arm 300 can drive the workpiece to move to the other multi-station abrasive belt mechanism 200 for fine grinding and polishing. This avoids repeated loading and unloading, saves time for changing equipment, and improves work efficiency.
[0052] Specifically, please refer to Figure 2 The multi-station sanding belt mechanism 200 also includes several liquid-cooled nozzles 223, which are located above the first sanding belt 212 and correspond one-to-one with the V-shaped grinding platform 224.
[0053] For example, the multi-station sanding belt mechanism 200 has four contact wheels 213, which cause the first sanding belt 212 to form four V-shaped grinding platforms 224. There are also four liquid cooling nozzles 223, with one liquid cooling nozzle 223 corresponding to one V-shaped grinding platform 224. When grinding four workpieces simultaneously, the four liquid cooling nozzles 223 can cool the four V-shaped grinding platforms 224 respectively to prevent thermal damage to the workpieces. The grinding fluid sprayed by the liquid cooling nozzles 223 has a lubricating effect, reduces frictional resistance, improves the surface finish of the workpiece, reduces scratches, and reduces power consumption. At the same time, the liquid cooling nozzles 223 can wash away debris and keep the workpiece clean during processing.
[0054] Specifically, please refer to Figure 4 The base 100 includes a first support base 110 and a second support base 120. The first support base 110 is provided with a first mounting part 111 for mounting a robot arm 300. The second support base 120 is located on the side of the first support base 110 away from the first mounting part 111. The second support base 120 is provided with two parallel second mounting parts 121 for mounting a multi-station sanding belt mechanism 200.
[0055] In this embodiment, a first mounting part 111 is provided on one side of the first bearing base 110, and a second bearing base 120 is provided on the other side. The first mounting part 111 is used to mount the robot arm 300. The second bearing base 120 is provided with two parallel second mounting parts 121, which are used to mount the multi-station belt sanding mechanism 200. For example, with two parallel multi-station belt sanding mechanisms 200 on the second bearing base 120, it can be understood that the robot arm 300 can move back and forth between the two multi-station belt sanding mechanisms 200. The robot arm 300 can clamp the workpiece and perform rough grinding and polishing in one of the multi-station belt sanding mechanisms 200, and then the robot arm 300 can drive the workpiece to move to the other multi-station belt sanding mechanism 200 for fine grinding and polishing. This avoids repeated loading and unloading, saves time for changing equipment, and improves work efficiency.
[0056] In summary, this application discloses an automated belt sander, comprising: a base, two parallel multi-station belt sanding mechanisms, and a robot arm. Both multi-station belt sanding mechanisms are mounted on the base, and the robot arm is movably mounted to hold workpieces, enabling polishing of the workpieces on the two multi-station belt sanding mechanisms. Each multi-station belt sanding mechanism includes a main body, a first sanding belt, several contact wheels, and several guide wheels. The main body is equipped with contact wheels and guide wheels. The first sanding belt is wound around the contact wheels and guide wheels. The contact wheels are arranged in a straight line, and the guide wheels are spaced apart from the contact wheels, forming multiple V-shaped grinding platforms arranged in a straight line on the contact wheels. In this application, the robot arm can hold the workpiece for rough polishing on one of the multi-station belt sanding mechanisms, and then move the workpiece to the other multi-station belt sanding mechanism for fine polishing. This avoids repeated loading and unloading, saves time on equipment changes, and improves work efficiency.
[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
