For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] For details, please refer to Figure 1 as well as Figure 2 As shown, a chair back robot grinding workstation for the woodworking industry includes a double-station turntable, the double-station turntable includes a turntable 1 installed on a rotating device, a front clamp 2 is installed on the outer edge of the turntable 1, a back clamp 3 is installed on the side of the turntable 1 opposite to the front clamp 2, a robot mounting seat 4 is installed on the bottom surface of the rotating device, a robot swing arm 5 is installed on the top surface of the robot mounting seat 4, and a grinding head 6 is installed on the end of the robot swing arm 5.

[0030] During the grinding process, a chair back is installed on the front clamp 2, and the back side of the chair back installed on the front clamp 2 faces, that is, the front side of the chair back faces the aforementioned front clamp 2. At the same time, another chair back is installed on the back clamp 3, and the back side of the chair back installed on the back clamp 3 faces the aforementioned back clamp 3, and the front side of the chair back clamped on the back clamp 3 faces upward. In this way, after different chair backs are clamped and fixed by the front clamp 2 and the back clamp 3, the rotating device is turned on to rotate the back clamp 3 or the front clamp 2 to the bottom of the grinding head 6 on the robot swing arm 5, and the rotation is stopped. The grinding is performed using the grinding head 6 on the robot swing arm 5. After the grinding is completed, the rotation is turned on again to rotate the front clamp 2 or the back clamp 3 under the grinding head 6 out, and the front clamp 2 or the back clamp 3 at the other end is rotated to the bottom of the grinding head 6, and then the grinding is continued. During the grinding, the chair back fixed on the front clamp 2 or the back clamp 3 that is rotated out from under the grinding head 6 can be replaced. , replace the new chair back, and after the grinding is completed, use the rotating device to rotate the front clamp 2 or the back clamp 3 of the replaced new chair back to under the grinding head 6 for grinding. At the same time, during the grinding process, the chair back that has been rotated out of the grinding head 6 can be disassembled and replaced. This not only allows the front clamp 2 to clamp the front of the chair back more stably, and the back clamp 3 to clamp the back of the chair back more stably, thereby making the grinding process safer, but also allows the new material to be disassembled and replaced at the same time during the grinding process, thereby greatly improving work efficiency and avoiding the situation where the grinding head 6 idles and does useless work during the replacement of the chair back.

[0031] Furthermore, the front clamp 2 includes a first support plate 21 installed on the edge of the turntable 1, and a first seat back fastening device is installed on the top surface of the first support plate 21. The first seat back fastening device includes support parts 22 arranged at both ends of the first support plate 21, and a first clamping part 23 arranged between the two support parts 22.

[0032] At the same time, the back clamp 3 includes a second support plate 31 installed on the edge of the turntable 1, and a second seat back fastening device is installed on the top surface of the second support plate 31. The second seat back fastening device includes support parts 22 arranged at both ends of the second support plate 31, and a second clamping part 32 arranged between the two support parts 22.

[0033] Specifically, the first clamping portion 23 includes a bottom column 231, the top surface of the bottom column 231 contacts the recessed surface of the seat back, the first clamping portion 23 also includes a vertical hydraulic plate 232 installed on the first support plate 21, the vertical hydraulic plate 232 passes through the gap on the seat back, and the first pressing end is arranged above the seat back and facing the seat back surface, the first pressing end of the vertical hydraulic plate 232 and the top surface of the bottom column 231 are arranged on the same line, and the first pressing end and the bottom column 231 clamp the seat back up and down.

[0034] The first pressing end and the bottom column 231 are used to clamp the chair back up and down, so that the chair back can be more stably combined with the front clamp 2 in an upwardly protruding state, thereby preventing the chair back from loosening and shaking during the grinding process.

[0035] Furthermore, the second clamping portion 32 includes a limiting plate 321, the side of which contacts the side of the middle rod of the chair back, and a double-headed horizontal hydraulic plate 322 is installed on the bottom surface of the limiting plate 321. The telescopic ends of the horizontal hydraulic plate 322 extend horizontally out of both sides of the chair back, and the second pressing end of the horizontal hydraulic plate 322 contacts the two side surfaces of the chair back. The second pressing end clamps the chair back left and right under the limiting action of the limiting plate 321.

[0036] Among them, the second pressing end is used to clamp the two sides of the chair back horizontally under the limiting action of the limiting plate 321, so that the chair back can be more stably combined with the back clamp 3 in a downwardly concave state, avoiding the chair back from loosening and shaking during the grinding process.

[0037] It should be noted that when the front clamp 2 is clamped, the first pressing end and the bottom column 231 are used to clamp the middle rod of the chair back, that is, the upper and lower surfaces of the middle rod are clamped.

[0038] In further words, please combine Figure 3 , Figure 4 as well as Figure 5 As shown, the distances between the two different support parts 22 and the rotation center of the turntable 1 are the same, and the support part 22 includes a base plate 221 installed on the top surface of the first support plate 21 or the second support plate 31, and the base plate 221 is provided with a mounting channel, and a support platform 222 is removably installed in the mounting channel, and the support platform 222 includes a mounting platform 2221, and a ball latch 2222 is installed on the mounting platform 2221 for disassembly combined with the mounting channel, and a support block 2223 is installed on the top surface of the mounting platform 2221, and the top surface of the support block 2223 is in contact with the backrest of the chair.

[0039] In this way, the mounting platform 2221 installed by the ball pin 2222 can be quickly disassembled and installed, and the support block 2223 installed on the top surface of the mounting platform 2221 is used to contact the frame of the chair back, that is, the structural rod perpendicular to the two ends of the aforementioned middle rod. By quickly disassembling and installing the mounting platform 2221, the mounting platform 2221 can be quickly replaced, so that different mounting platforms 2221 are prepared, that is, mounting platforms 2221 with different spacings between the support blocks 2223 on the mounting platform 2221, so that the mounting platform 2221 can provide good support for chair backs of different specifications. The mounting platform 2221 can be adapted to more chair backs of different specifications, and can be easily replaced, thereby improving work efficiency on the one hand, and greatly reducing production costs on the other hand, avoiding the replacement of different grinding equipment to adapt it to chair backs of different specifications.

[0040] Furthermore, the ball latch 2222 includes a fixing rod vertically passing through the mounting platform 2221, and the fixing rod passes through the bottom side of the mounting platform 2221 and is installed with a ball for positioning. The support platform 222 includes a hard base fixed to the mounting platform 2221, and a rubber block is installed on the top surface of the hard base.

[0041] The rubber block is then used to increase the friction between the chair back and the top surface of the hard base. The hard base is used to contact the chair back, that is, to support the chair back.

[0042] Further, please combine Figure 1 As shown, the robot swing arm 5 is arranged in a workshop 7, a feeding channel 8 is arranged on one side of the workshop 7, the rotation center of the turntable 1 is arranged directly below the top of the feeding channel 8, the diameter of the turntable 1 is the same as the width of the feeding channel 8, and a baffle 9 parallel to the back clamp 3 and the front clamp 2 is installed on the top surface of the turntable 1, the baffle 9 passes through the center of the turntable 1, and the top of the baffle 9 is in sliding contact with the top of the feeding channel 8.

[0043] In this way, during the grinding process, the entire grinding process is set in a relatively closed environment, which means that the workers can be well protected. Specifically, the grinding is carried out in the workshop 7, and the exit of the workshop 7 is blocked by the baffle 9. In other words, the flying chips generated during the grinding process of the chair back can be effectively blocked by the baffle 9 and the workshop 7, thereby preventing the flying chips from causing harm to the workers.

[0044] Furthermore, a fence 10 extending outward is installed on the outer side of the feeding channel 8, and a safety grating 11 for detecting the passage of people is installed on the side of the fence 10 facing the turntable 1.

[0045] In addition, an inlet and outlet passage is provided on the side of the workshop 7 and a blocking door 12 is hingedly connected thereto.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
