Description

Technical Field

[0001] This invention belongs to the field of wood box polishing technology, specifically an automatic wood box polishing machine. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It mainly uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. The main purpose of polishing is to improve the gloss of the object's surface.

[0003] Wooden boxes, prized for their rustic and substantial feel, are frequently used in the packaging of various high-end consumer goods. To achieve a smooth finish without sharp edges or burrs, finished wooden boxes require polishing. Current polishing methods primarily rely on manual labor, a tedious and slow process that involves constant hand movement, leading to fatigue and low production efficiency. Furthermore, uneven polishing often results in inconsistent product quality. Due to this low efficiency, additional workers are often hired to ensure on-time delivery, increasing labor costs. Summary of the Invention

[0004] To address the problems mentioned above, this invention provides an automatic wooden box polishing machine. By setting up a feeding device, a polishing device, and a robotic arm, the machine achieves full automation of wooden box polishing. During the polishing process, the robotic arm allows the wooden box to rotate 360°, ensuring that all surfaces to be polished are polished from all angles.

[0005] The present invention adopts the following technical solution:

[0006] An automatic wooden box polishing machine includes a feeding device, a polishing device located on one side of the feeding device, and a robotic arm that reciprocates between the feeding device and the polishing device.

[0007] The feeding device includes a frame, a lowering layer and an uppering layer laid on top of the frame.

The uppering layer includes several uppering slides arranged side by side along the length of the frame. The uppering slides are inclined downwards in the direction close to the robot arm.

[0008] The side of the unloading layer closest to the robotic arm protrudes outward from the loading layer, and the protruding unloading chute can accommodate at least one wooden box.

[0009] Furthermore, both the loading and unloading chute include two spaced-apart limit plates and two support rollers located between the two limit plates, and both the loading and unloading chute have baffles at their tail ends.

[0010] Furthermore, a crossbeam extending along the length of the frame is provided above the feeding layer. The crossbeam is mounted on the frame, and a cylinder is fixed to one end of the crossbeam. The extension and retraction end of the cylinder is connected to a drive shaft. The drive shaft is arranged parallel to the crossbeam and extends from one side of the feeding layer to the opposite side.

[0011] Several sorting mechanisms are spaced apart on the drive shaft. The number of sorting mechanisms is the same as the number of feeding slides, and they are set one-to-one with the feeding slides.

[0012] Furthermore, the sorting mechanism includes a support seat, a spring, a first linear bearing, and a retaining ring, which are sequentially mounted on the drive shaft along the direction close to the cylinder. The bottom of the support seat is fixedly connected to the crossbeam, one end of the spring abuts against the support seat, and the other end abuts against the first linear bearing.

[0013] A support shaft parallel to the drive shaft is fixed on the support base. A second linear bearing is mounted on the support shaft. A sorting plate is fixed on the first and second linear bearings. A sorting block is fixed to the lower end of the sorting plate. The sorting block slides on the drive shaft with the first linear bearing.

[0014] Furthermore, the polishing device includes a polishing base and a polishing wheel mechanism. The polishing base is equipped with a slide rail, and the polishing wheel mechanism is slidably mounted on the slide rail via a sliding plate.

[0015] The polishing wheel mechanism includes a first motor fixed on the slide plate, an intermediate transmission component connected to the first motor, and a polishing wheel connected to the intermediate transmission component. A waste collection bin is provided below the polishing wheel.

[0016] Furthermore, a waxing bracket is also mounted on the polishing base. The waxing bracket is slidably mounted on the polishing base in the direction of the polishing wheel. A transverse moving component that moves along the axial direction of the polishing wheel is installed on the waxing bracket. A wax wiping component is fixed on the transverse moving component. The wax wiping component is located above the polishing wheel and moves transversely with the moving part of the transverse moving component.

[0017] Furthermore, the waxing assembly includes a waxing mounting plate fixedly connected to the moving part of the transverse moving assembly, a second motor fixedly mounted on the waxing mounting plate, a first screw fixedly connected to the output end of the second motor, and a first nut sleeve fitted on the first screw, with a waxing base plate fixedly mounted on the first nut sleeve;

[0018] A third motor is fixed on the waxing base plate. The output end of the third motor is connected to a second screw. A second nut sleeve is fitted on the second screw. A wax block is fixed on the second nut sleeve. The wax block is placed in a fixed wax groove. The third motor drives the wax block to move downward in the fixed wax groove.

[0019] Furthermore, the polishing base is also equipped with a cloth scraper mounting seat, on which a geared motor is fixed. The output shaft of the geared motor is connected to an eccentric shaft, on which a first joint bearing is mounted. The first joint bearing is connected to a second joint bearing via a joint bearing connecting shaft. The second joint bearing is mounted on a rocking shaft, and a toothed rocking mounting plate is fixed to the end of the rocking shaft. A cloth wheel napper is mounted on the toothed rocking mounting plate.

[0020] Furthermore, the cloth scraper mounting base is provided with a track extending along the axial direction of the polishing wheel. The toothed knife swing mounting plate is slidably connected to the track via a slider. The geared motor drives the eccentric shaft to rotate, and the eccentric shaft drives the cloth wheel napper to move back and forth along the track.

[0021] Furthermore, the robotic arm includes a robotic arm and a mechanical gripper connected to the robotic arm. The mechanical gripper includes a wooden box clamp, which is connected to a pneumatic device that drives the wooden box clamp to expand outward or contract inward.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) The automatic wooden box polishing machine of the present invention realizes the full automation of wooden box polishing by setting up a feeding device, a polishing device and a robot. During the polishing process, the robot can rotate the wooden box 360°, and all surfaces to be polished can be polished in all directions. The feeding device of the present invention includes an inclined loading slide and a unloading slide. During the loading process, the wooden box automatically slides to the robot gripping position through the loading slide, and during the unloading process, it automatically moves to the manual unloading position through the unloading slide. The entire process only requires one employee to complete the loading and unloading of the wooden box. The loading and unloading positions are a certain distance away from the polishing position to avoid the harm of dust to the human body during polishing.

[0024] (2) The automatic wooden box polishing machine of the present invention has several sorting mechanisms on the feeding layer. When the wooden boxes are not arranged neatly on the feeding slide, the sorting mechanism shakes left and right under the drive of the cylinder to sort the wooden boxes back into place, making it convenient for the robot arm to grab them.

[0025] (3) The automatic wooden box polishing machine of the present invention is equipped with a waxing component on the polishing mechanism. During the polishing process, the waxing component will automatically apply wax to the polishing wheel. Polishing and waxing are carried out at the same time, making the polished wooden box brighter, more lustrous, more beautiful and more upscale. Attached Figure Description

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0039] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The invention is described in detail with specific embodiments.

[0040] like Figure 1-8As shown, this invention provides an automatic wooden box polishing machine, including a feeding device 1, a polishing device 2 located on one side of the feeding device 1, and a robotic arm 3 that reciprocates between the feeding device and the polishing device. The robotic arm 3 is used to grab wooden boxes from the feeding device 1 and move them to the polishing device 2, where the polishing device 2 performs 360° all-around polishing on the wooden boxes. The feeding device 1 includes a frame 11, a lowering layer 12 and an uppering layer 13 sequentially laid on top of the frame 11. The lowering layer 12 includes several lowering slides 121 arranged side by side along the length of the frame 1, with the lowering slides 121 inclined downwards away from the robotic arm 3. The uppering layer 13 includes several uppering slides 131 arranged side by side along the length of the frame 1, with the uppering slides 131 inclined downwards towards the robotic arm 3. During operation, the worker stands on the longer side of the frame 1 away from the robotic arm 3 and manually places the wooden box to be polished on the higher side of the uppering slide 131. The wooden box moves downwards along the loading slide 131 to the gripping position of the robotic arm 3 (i.e., the lowest end of the loading slide 131), waiting to be gripped by the robotic arm 3. After the wooden box is polished, the finished wooden box is placed on the higher side of the unloading slide 121 and moves downwards along the unloading slide 121 to the manual removal position (i.e., the lowest end of the unloading slide 121), waiting to be removed manually. To achieve unattended operation, workers can fill the loading layer with wooden boxes to be polished and then leave, avoiding dust generated during polishing. Once the wooden boxes are polished, the workers remove all the finished wooden boxes from the unloading layer and begin the next round of loading. To facilitate the robotic arm 3 in placing the finished wooden boxes vertically downwards onto the unloading slide 121, the side of the unloading layer 12 closest to the robotic arm 3 protrudes outwards from the loading layer 13, and the protruding unloading slide 121 can accommodate at least one wooden box, so that the robotic arm 3 can place the polished wooden box onto the unloading slide 121 without interfering with the loading slide 131.

[0041] For details, see Figures 2 to 4 Both the loading slide 131 and the unloading slide 121 include two spaced-apart limit baffles 122 and two support rollers 123 located between the two limit baffles 122. The tail end of the loading slide 131 and the unloading slide 121 is provided with a baffle 124. The distance between the two limit baffles 122 is adapted to the length or width of the wooden box, or in other words, the distance between the two limit baffles 122 allows it to match wooden boxes of various sizes. Only one wooden box can be accommodated between the two limit baffles 122, ensuring that the wooden boxes are arranged neatly during loading and unloading to the greatest extent. After the wooden box is placed in the loading slide 131 or the unloading slide 121, it slides downward under the action of the bottom support rollers 123 to realize the automatic loading and unloading process. The baffle 124 is provided at the tail end of the slide to prevent the wooden box from sliding out of the feeding device 1.

[0042] Specifically, a crossbeam 132 extending along the length of the frame 11 is provided above the feeding layer 13. The crossbeam 132 is mounted on the frame 11, and a cylinder 133 is fixed to one end of the crossbeam 132. The telescopic end of the cylinder 133 is connected to a drive shaft 134 through a coupling. The drive shaft 134 is arranged parallel to the crossbeam 132 and extends from one side of the feeding layer 13 to the opposite side. Several sorting mechanisms 14 are spaced on the drive shaft 134. The number of sorting mechanisms 14 is the same as the number of feeding slides 131, and they are arranged one-to-one with the feeding slides 131. When the wooden boxes are not arranged neatly on the feeding slides 131, the sorting mechanism 14 will sway left and right under the drive of the cylinder 133 to sort the wooden boxes into place, making it convenient for the robot arm 3 to grasp them.

[0043] For details, see Figure 4 The sorting mechanism 14 includes a support seat 141, a spring 142, a first linear bearing 143, and a retaining ring 144, which are sequentially mounted on the drive shaft 134 along the direction close to the cylinder 133. The bottom of the support seat 141 is fixedly connected to the crossbeam 132. The support seat 141 supports the drive shaft 134. A through hole is provided on the upper part of the support seat 141, and a third linear bearing (not shown in the figure) is coaxially installed in the through hole. The support seat 141 is mounted on the drive shaft 134 through the third linear bearing, and the drive shaft 134 can move left and right relative to the through hole. The spring 142 is located between the support seat 141 and the first linear bearing 143. One end of the spring 142 abuts against the support seat 141, and the other end abuts against the first linear bearing 143. The retaining ring 144 is fixed on the drive shaft 134. A support shaft 145 parallel to the drive shaft 134 is fixed on the support seat 141, and a second linear bearing is mounted on the support shaft 145. A sorting plate 147 is fixed on bearing 146, first linear bearing 143, and second linear bearing 146. A sorting block (not shown in the figure) is fixed to the lower end of sorting plate 147. The sorting block slides on drive shaft 134 with first linear bearing 143 and second linear bearing 146. When the wooden boxes are not arranged neatly, cylinder 133 starts and drives drive shaft 134 to move left and right. Since fixed ring 144 is fixed to drive shaft 134, when drive shaft 134 moves to the left, first linear bearing 143 moves to the left through fixed ring 144. At the same time, since the position of support seat 141 is fixed, first linear bearing 143 compresses spring 142 to the left. Spring 142 is in a compressed state. When drive shaft 134 moves to the right, spring 142 applies a rightward force to first linear bearing 413, driving first linear bearing to move to the right. Finally, the sorting plate and sorting block sway left and right.

[0044] For details, see Figure 2Each loading chute 131 and each unloading chute 121 is equipped with a sensor to detect whether the loading layer 13 and unloading layer 12 are full. The sensor is connected to the equipment control system. When the sensor on the loading chute 131 detects that the loading layer 13 is full, the equipment automatically stops working. Similarly, when the sensor on the unloading chute 121 detects that the unloading layer 12 is full, the equipment also automatically stops working. In addition, each loading chute 131 is equipped with a sensor 148 at the end to detect whether the wooden boxes are arranged neatly. When the sensor 148 detects that the wooden boxes on the loading chute 131 are not arranged neatly, the equipment control system controls the cylinder 133 to start. The sorting plate 147 and the sorting block sway left and right under the drive of the cylinder 133 to sort the untidy wooden boxes into place, making it convenient for the robot arm to pick them up.

[0045] For details, see Figure 5 , Figure 6 The polishing device 2 includes a polishing base 21 and a polishing wheel mechanism 22. The polishing base 21 is provided with a slide rail 211, which extends along the length of the frame 11. The polishing wheel mechanism 22 is slidably mounted on the slide rail 211 via a sliding plate 212. The polishing wheel mechanism 22 can move towards the robot 3 or away from the robot 3. Preferably, the polishing wheel mechanism 22 is driven to slide along the slide rail by a drive mechanism, which includes a motor and a lead screw and nut assembly connected to the motor. The polishing wheel mechanism 22 includes a first motor 221 fixed on the sliding plate 212, an intermediate transmission assembly 222 connected to the first motor 221, and a polishing wheel 223 connected to the intermediate transmission assembly 222. A waste collection bin 224 is provided below the polishing wheel 223. The waste collection bin 224 is used to collect the debris and dust generated during polishing. Optionally, the intermediate transmission assembly 224 is a belt drive assembly. Of course, in other embodiments, the intermediate transmission assembly can also be a gear drive assembly. Those skilled in the art can design according to the actual working conditions. In addition, to prevent dust generated during polishing from falling onto the slide rails and affecting the smoothness of the polishing mechanism, dust covers that can move back and forth are provided at both ends of the slide rails. It should be noted that all slide rails or tracks in the polishing device of this invention are equipped with dust covers.

[0046] Specifically, a waxing bracket 23 is also mounted on the polishing base 21. The waxing bracket 23 is slidably mounted on the polishing base 21 in the direction of the polishing wheel 223. Optionally, the waxing bracket 23 and the polishing wheel mechanism 22 slide in the same direction and are both driven by the same drive mechanism. A transverse moving component 24 that moves along the axial direction of the polishing wheel 223 is mounted on the waxing bracket 23. A wax wiping component 25 is fixed on the transverse moving component 24. The wax wiping component 25 is located above the polishing wheel 223 and moves laterally with the moving part of the transverse moving component 24. The transverse moving component 24 includes a fourth motor 241 fixed on the waxing bracket 23, a third screw 242 fixedly connected to the output end of the fourth motor 241, and a third nut sleeve 243 fitted on the third screw 242. The third nut sleeve 243 is the moving part of the transverse moving component 24. The wax wiping component 25 is fixedly mounted on the third nut sleeve 243.

[0047] For details, see Figure 6 The waxing assembly 25 includes a waxing mounting plate 251 fixedly connected to the moving part of the transverse moving assembly 24, a second motor 252 fixedly mounted on the waxing mounting plate 251, a first screw 253 fixedly connected to the output end of the second motor 252, and a first nut sleeve 254 fitted on the first screw 253. A waxing base plate 255 is fixedly mounted on the first nut sleeve 254. A third motor 256 is fixedly mounted on the waxing base plate 255. A second screw 257 is connected to the output end of the third motor 256. A second nut sleeve 258 is fitted on the second screw 257. A wax block 259 is fixed on the second nut sleeve 258. The wax block 259 is disposed in a fixed wax groove 260. The third motor 256 drives the wax block 259 to move downward in the fixed wax groove 260, and the second motor 252 drives the waxing base plate 255 to move up and down, thereby driving the fixed wax groove 260 and the wax block 259 in the fixed wax groove to move up and down.

[0048] In this invention, the waxing component 25 can move back and forth, left and right, and up and down to accurately and evenly apply the wax block 259 to the polishing wheel 223, thereby achieving uniform polishing of the wooden box and making the polished wooden box brighter, more lustrous, more beautiful and more upscale.

[0049] For details, see Figure 7The polishing base 21 is also equipped with a scraper mounting seat 26. A reduction motor 261 is fixed on the scraper mounting seat 26. The output shaft of the reduction motor 261 is connected to an eccentric shaft (not shown in the figure). A first joint bearing 262 is mounted on the eccentric shaft. The first joint bearing 262 is connected to a second joint bearing 263 through a joint bearing connecting shaft. The second joint shaft 263 is mounted on a rocker shaft 264. A toothed knife rocker mounting plate 265 is fixed to the end of the rocker shaft 264. A cloth wheel napper 266 is mounted on the toothed knife rocker mounting plate 265. The scraper mounting seat 26 is provided with a track extending along the axial direction of the polishing wheel 223. The toothed knife rocker mounting plate 265 is slidably connected to the track by a slider. The reduction motor 261 drives the eccentric shaft to rotate, and the eccentric shaft drives the cloth wheel napper 266 to reciprocate along the track. When it is necessary to clean the dust and stains on the polishing wheel 223, the polishing wheel mechanism 22 is controlled to move backward along the slide rail until it contacts the cloth wheel furrler 266. The polishing wheel 223 is cleaned by the reciprocating left and right movement of the cloth wheel furrler 266.

[0050] For details, see Figure 8 The robotic arm 3 includes a robotic arm and a mechanical gripper connected to the robotic arm. The mechanical gripper includes a wooden box clamp 31, which is connected to a pneumatic device. The pneumatic device drives the wooden box clamp 31 to expand outward or retract inward. During loading, the wooden box clamp 31 moves to the wooden box, the pneumatic device inhales air to expand the wooden box clamp 31, and the wooden box clamp 31 is fixed inside the wooden box, thereby gripping the wooden box and placing it on the polishing wheel 223 for polishing. During unloading, the wooden box clamp 31 moves the finished wooden box to the unloading slide 121, the pneumatic device releases air to retract the wooden box clamp 31 inward, and the finished wooden box is placed on the unloading slide 121. The robotic arm 3 of this invention can rotate the wooden box clamp 31 360°, so that all surfaces on the wooden box that need polishing can be polished from all angles.

[0051] In the process of using the polishing machine of the present invention, the wooden boxes to be polished are first loaded onto the loading layer 13. After the loading layer 13 is full, the loading is stopped. The robot arm 3 uses the wooden box clamp 31 to pick up a wooden box from the loading layer 13 and move it to the polishing wheel 223 for all-round polishing. After polishing, the robot arm 3 puts the finished product into the unloading layer 12. This cycle realizes the full automation of wooden box polishing production, which significantly increases the output of wooden box polishing per unit time and improves the product quality of wooden box polishing.

[0052] The polishing machine of this invention is also equipped with a control panel adapted to the polishing machine. When using the polishing machine of this invention for the first time, the machine parameters are set on the control panel. When polishing the same type of wooden box in subsequent use, simply press the start button and the machine will start running automatically. No operation is required in the middle. After polishing is completed, press the close button and the machine will turn off. During the polishing process, no human supervision is required. Only the finished wooden boxes on the unattended material layer need to be fed at regular intervals and removed at regular intervals. The unattended polishing process greatly avoids the harm to the employees' health caused by inhaling dust during production.

[0053] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
