Description

Technical Field

[0001] This invention belongs to the technical field of sanding devices for furniture production, specifically relating to a sanding device for furniture production and its usage method. Background Technology

[0002] Solid wood tables are widely favored for their environmentally friendly materials, elegant lines and textures, and durability. However, for furniture manufacturers, there are many problems to be solved in the processing of solid wood tables. One of them is that the surface of the raw wood boards for solid wood tables is often relatively rough, and multiple processes such as sanding and polishing are required to fully bring out the texture of the wood.

[0003] However, current technology mostly relies on manual sanding, which makes it difficult to precisely control the sanding depth. This often results in over-sanding or under-sanding, causing the wood to become thinner and failing to meet usage requirements, thus becoming defective products. The production process also generates a large amount of sawdust, which can affect the health of workers. Furthermore, existing sanding equipment cannot sand the tabletop and legs separately, requiring the legs to be sanded manually, making the production process cumbersome. When sanding the legs, only a uniform appearance can be achieved, resulting in furniture with a monotonous style that cannot meet the diverse needs of consumers. Summary of the Invention

[0004] The purpose of this invention is to provide a sanding device for furniture production and its method of use, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sanding device for furniture production and its usage method, comprising a box and a partition.

[0006] The present invention further illustrates that the first suction pipe is fixedly installed on the top of the first robotic arm, and the first suction hole is opened around the first rotary seat. The second suction pipe is fixedly installed on the top of the second robotic arm, and the second suction hole is opened around the second rotary seat.

[0007] The present invention further describes that the box body includes a first fixed seat, a second fixed seat, a sawdust collection trough, a support seat, a pressure sensor, and a partition. The first fixed seat is fixedly installed on one side of the bottom of the box body, the second fixed seat is fixedly installed on the other side of the bottom of the box body, the sawdust collection trough is opened at the bottom of the box body, the support seat array is arranged on the bottom surface of the box body and located in the sawdust collection trough, the pressure sensor is fixedly installed on the top surface of the support seat, and the partition is fixedly installed on the top side wall of the box body.

[0008] The present invention further illustrates that the clamping assembly includes a first robotic arm and a second robotic arm, wherein the first robotic arm is fixedly mounted on a first fixed base and the second robotic arm is fixedly mounted on a second fixed base.

[0009] The present invention further describes that the collection assembly includes a collection box, a first chamber, a second chamber, a third chamber, a first vent pipe, a second vent pipe, a third vent pipe, a first air pump, and a second air pump. The collection box is disposed on one side of the box body, below the partition. The interior of the collection box is hollow and sequentially divided into the first chamber, the second chamber, and the third chamber. One end of the first vent pipe extends through the top of the collection box into the first chamber, and the other end extends through the partition and is connected to the flexible hose on the first suction pipe. One end of the second vent pipe extends through the top of the collection box into the second chamber, and the other end extends through the partition. One end of the third vent pipe extends through the top of the collection box into the third chamber, and the other end extends through the partition and is connected to the flexible hose on the second suction pipe. The first air pump is fixedly installed on the first vent pipe, and the second air pump is fixedly installed on the second vent pipe.

[0010] The present invention further illustrates that the dust removal assembly includes a third robotic arm and an air compressor. The third robotic arm is fixedly installed on the partition and located between the first robotic arm and the second robotic arm. The air compressor is fixedly installed inside the collection box and located in the second chamber.

[0011] The present invention further illustrates that the identification component includes a first camera and a second camera, wherein the first camera is fixedly installed on one side of the partition and the second camera is fixedly installed on the other side of the partition.

[0012] The specific method is as follows: S1. When the desktop needs to be polished, the equipment program controls the downward pressure of the two sets of robotic arms to M1. When the equipment program detects that the pressure value has reached M1, it controls the two sets of rotating wheels to start rotating. At this time, the rotation speed of the two sets of rotating wheels is V3 and there is no need to adjust the pressure value. S2. When a shallower level of sanding is required on the desktop, the device program controls the downward pressure of the two sets of robotic arms to M2. When the device program detects that the pressure value has reached M2, it controls the two sets of rotating wheels to open at a speed of V3. At this time, the device program monitors the pressure values ​​of the two sets of pressure sensors. When the pressure value exceeds the error value, the device program controls the rotation speed of the two sets of rotating wheels to V2. At this time, the device program continues to monitor the pressure values ​​of the two sets of pressure sensors. When the pressure value changes to M1, the device program controls the rotation speed of the two sets of rotating wheels to V1 for slow sanding to prevent excessive sanding of the desktop due to excessive speed, which could cause dimensional deviations. S3. When deep sanding of the desktop is required, the equipment program controls the downward pressure of the two sets of robotic arms to M3, and then controls the two sets of rotating wheels to start at a speed of V3. At this time, the equipment program monitors the pressure values ​​of the two pressure sensors. When the pressure value exceeds the error, there is no need to reduce the speed until the pressure value changes to M1. Then, the equipment program controls the speed of the two sets of rotating wheels to V1. The equipment program controls the sanding time to T1. After the sanding time T1 is up, the equipment program controls the next operation.

[0013] The specific method is as follows: S1. When the equipment program detects a pressure value of N1, the equipment program determines that the table is too light and the table legs can be sanded thinner for a better appearance. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H3 and the rotation speed to V3. The two sets of robotic arms rotate around the table legs and move from top to bottom to sand the table legs into a tapered shape that is thicker at the top and thinner at the bottom, so as to make the table more beautiful while ensuring that it can be used normally. S2. When the equipment program detects a pressure value of N2, it determines that the table is of normal weight and the table legs can be ground thinner. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H2 and the rotation speed to V3. The two sets of robotic arms rotate around the table legs and move from top to bottom, grinding the table legs into a tapered shape that is thicker at the top and thinner at the bottom (the taper is smaller than when the pressure value is N1). S3. When the equipment program detects a pressure value of N3, it determines that the table is too heavy and cannot be tapered to ensure normal use. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H1 and the rotation speed to V3 to perform normal polishing on the table legs. The equipment program sets the table leg polishing time to T2. When the polishing time T2 is up, the equipment program controls the next operation.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, through the grinding assembly, includes a first robotic arm, a first suction pipe, a first rotary wheel seat, a first suction hole, a first rotary wheel, a second robotic arm, a second suction pipe, a second rotary wheel seat, a second suction hole, and a second rotary wheel. The first robotic arm is fixedly installed at one end of the partition, the first rotary wheel seat is disposed at one end of the first robotic arm, the first rotary wheel bearing is connected to the first rotary wheel seat, and sandpaper is detachably installed around the wheel surface of the first rotary wheel. The second robotic arm is fixedly installed at the other end of the partition, and the second rotary wheel... The wheel seat is located at one end of the second robotic arm, and the second rotating wheel bearing is connected to the second rotating wheel seat. Sandpaper is detachably installed around the wheel surface of the second rotating wheel. The support base array is located on the bottom surface of the housing, and the pressure sensor is fixedly installed on the top surface of the support base. Through the coordinated use of four sets of pressure sensors, two sets of rotating wheels, and the equipment program, the weight of the table can be detected, and the tilt angle of the two sets of rotating wheels can be changed according to the weight of the table to perform different taper grinding on the table legs, making the finished table more beautiful, increasing the diversity of the table's appearance, and meeting the different needs of consumers.

The housing 1 is equipped with a device program that can control the movement of three sets of robotic arms, the start and stop of two sets of rotating wheels, the movement of two sets of robotic hands, the start and stop of the air compressor 52, and the signal connection of two sets of cameras. The housing 1 provides power to the internal devices via an external power supply. Both sets of cameras are connected to the equipment program signals, and the built-in pressure sensors of the two sets of rotating wheel seats are also connected to the equipment program signals. Example 1:

[0019] When the staff needs to sand the table, they turn on the power of the box 1, the equipment program starts, and then the staff places the table in the sawdust collection trough 14 inside the box 1. The equipment program identifies the position of the table through two sets of cameras and then begins the sanding operation. Desktop sanding operation: Once the device program detects the table's position via two sets of cameras, it controls the first robotic arm 21 and the second robotic arm 22 to descend, while the third robotic arm 51 remains stationary. When the two sets of rotating wheels contact the tabletop, the device program detects the pressure values ​​of the built-in pressure sensors inside the wheel seats. The device program sets the polishing pressure values ​​to M1, M2, and M3, and the rotational speeds of the two sets of rotating wheels to V1, V2, and V3, with a pressure value error of ±10. When surface polishing of the tabletop is required, the device program controls the two robotic arms to apply downward pressure of M1. When the device program detects that the pressure value has reached M1, it controls the two sets of rotating wheels to start rotating. At this time, the rotational speed of the two sets of rotating wheels is V3, and no pressure value adjustment is required. When shallower polishing of the tabletop is required, the device program controls the two robotic arms to apply downward pressure of M2. When the device program detects that the pressure value has reached M2, it controls the two sets of rotating wheels to... Start the machine at speed V3. The device program monitors the pressure values ​​of the two pressure sensors. When the pressure exceeds the error value, the device program controls the rotation speed of the two sets of rollers to V2. The device program continues to monitor the pressure values ​​of the two pressure sensors. When the pressure value changes to M1, the device program controls the rotation speed of the two sets of rollers to V1 for slow polishing to prevent over-polishing of the tabletop due to excessive speed and dimensional deviation. When deep polishing of the tabletop is required, the device program controls the downward pressure of the two robotic arms to M3, and then controls the two sets of rollers to start at a speed of V3. The device program monitors the pressure values ​​of the two pressure sensors. When the pressure value exceeds the error, there is no need to reduce the speed until the pressure value changes to M1. The device program controls the rotation speed of the two sets of rollers to V1. The device program controls the polishing time to T1. After polishing time T1 is reached, the device program controls the next operation. The built-in pressure sensors in the two sets of rotating wheels work in conjunction with the equipment program to control the pressure value during sanding, thereby controlling the depth of sanding and preventing over-sanding of furniture tables that could cause dimensional deviations. This can reduce the scrap rate in production. With the cooperation of the two sets of rotating wheels and two sets of robotic arms, no manual operation is required during sanding, which can reduce the workload of the workers.

[0020] Table leg sanding process: After the tabletop is sanded, the table legs need to be sanded. At this time, the equipment program controls the first robotic arm 21 and the second robotic arm 22 to rise, while the third robotic arm 51 remains stationary. Then, the equipment program uses two sets of cameras to identify the position of the table and controls the two sets of robotic arms to grip the tabletop. Once the two sets of robotic arms have gripped the table, the equipment program controls the two sets of robotic arms to rotate, flipping the table so that the tabletop is placed face down on the four sets of support seats 15. Then, the equipment program controls the first robotic arm 21 and the second robotic arm 22 to descend to the table leg position. At this time, the equipment program detects the pressure values ​​of the four pressure sensors 151 on the four sets of support seats 15. The equipment program sets the pressure values ​​to N1, N2, and N3, and the tilt angles of the two sets of rotating wheels to H1, H2, and H3. When the equipment program detects a pressure value of N1, it determines that the table is too light and the table legs can be sanded finer for a better appearance. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H3 and the rotation speed to V3. Two sets of robotic arms rotate around the table legs and move from top to bottom, polishing the legs into a tapered shape that is thicker at the top and thinner at the bottom. This ensures the table can be used normally while also improving its appearance. When the equipment program detects a pressure value of N2, it determines that the table is of normal weight and the legs can be polished thinner. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H2 and the rotation speed to V3. The two sets of robotic arms rotate around the table legs and move from top to bottom, polishing the legs into a tapered shape that is thicker at the top and thinner at the bottom (the taper is smaller than when the pressure value is N1). When the equipment program detects a pressure value of N3, it determines that the table is too heavy. To ensure normal use, the taper cannot be polished. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H1 and the rotation speed to V3, performing normal polishing on the table legs. The equipment program sets the table leg polishing time to T2. After polishing time T2 is reached, the equipment program controls the next operation. By using four pressure sensors 151, two sets of rotating wheels, and the equipment program, the weight of the table can be detected and the tilt angle of the two sets of rotating wheels can be changed according to the weight of the table to polish the table legs with different tapers, making the finished table more beautiful, increasing the diversity of the table's appearance, and meeting the different needs of consumers.

[0021] Dust removal operation: After the table is sanded, the equipment program controls the first robotic arm 21 and the second robotic arm 22 to rise, the third robotic arm 51 to fall, and the air compressor 52 to start. The third robotic arm 51 sprays air onto the table to blow the remaining wood chips onto the wood chip collection tank 14 for easy cleaning by the staff. The equipment program sets the blowing time to T3. When T3 is reached, the equipment program controls the third robotic arm 51 to rise and the air compressor 52 to turn off. During the above-mentioned sanding operation, the equipment program controls the first air pump 431 and the second air pump 432 to be kept running. The two sets of air pumps suck the wood dust generated during sanding from the first air extraction hole 213 and the second air extraction hole 223 into the first air extraction pipe 211 and the second air extraction pipe 221. Then, it is transmitted through the hose to the first vent pipe 421 and the third vent pipe 423, and finally enters the first chamber 411 and the third chamber 413 for easy cleaning by the staff.

8. A sanding device for furniture production according to claim 7, characterized in that: The specific method is as follows: S1. When the desktop needs to be polished, the equipment program controls the downward pressure of the two sets of robotic arms to M1. When the equipment program detects that the pressure value has reached M1, it controls the two sets of rotating wheels to start rotating. At this time, the rotation speed of the two sets of rotating wheels is V3 and there is no need to adjust the pressure value. S2. When a shallower level of sanding is required on the desktop, the device program controls the downward pressure of the two sets of robotic arms to M2. When the device program detects that the pressure value has reached M2, it controls the two sets of rotating wheels to open at a speed of V3. At this time, the device program monitors the pressure values ​​of the two sets of pressure sensors. When the pressure value exceeds the error value, the device program controls the rotation speed of the two sets of rotating wheels to V2. At this time, the device program continues to monitor the pressure values ​​of the two sets of pressure sensors. When the pressure value changes to M1, the device program controls the rotation speed of the two sets of rotating wheels to V1 for slow sanding to prevent excessive sanding of the desktop due to excessive speed, which could cause dimensional deviations. S3. When deep sanding of the desktop is required, the equipment program controls the downward pressure of the two sets of robotic arms to M3, and then controls the two sets of rotating wheels to start at a speed of V3. At this time, the equipment program monitors the pressure values ​​of the two pressure sensors. When the pressure value exceeds the error, there is no need to reduce the speed until the pressure value changes to M1. Then, the equipment program controls the speed of the two sets of rotating wheels to V1. The equipment program controls the sanding time to T1. After the sanding time T1 is up, the equipment program controls the next operation.

9. A sanding device for furniture production according to claim 8, characterized in that: The specific method is as follows: S1. When the equipment program detects a pressure value of N1, the equipment program determines that the table is too light and the table legs can be sanded thinner for a better appearance. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H3 and the rotation speed to V3. The two sets of robotic arms rotate around the table legs and move from top to bottom to sand the table legs into a tapered shape that is thicker at the top and thinner at the bottom, so as to make the table more beautiful while ensuring that it can be used normally. S2. When the equipment program detects a pressure value of N2, it determines that the table is of normal weight and the table legs can be ground thinner. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H2 and the rotation speed to V3. The two sets of robotic arms rotate around the table legs and move from top to bottom, grinding the table legs into a tapered shape that is thicker at the top and thinner at the bottom (the taper is smaller than when the pressure value is N1). S3. When the equipment program detects a pressure value of N3, it determines that the table is too heavy and cannot be tapered to ensure normal use. At this time, the equipment program controls the tilt angle of the two sets of rotating wheels to H1 and the rotation speed to V3 to perform normal polishing on the table legs. The equipment program sets the table leg polishing time to T2. When the polishing time T2 is up, the equipment program controls the next operation.
