[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0040] Example 1

[0041] See also Figures 1 to 5 An automatic panel turning machine for panel furniture based on visual inspection includes a base plate 1, a placement rack 3 for placing a plurality of panels 4 is provided on the base plate 1, the placement rack 3 is mounted on the base plate 1 through a support frame 2, a vertical support plate 43 is provided on one side of the placement rack 3, a visual inspection probe 54 for visual inspection is provided on the top of the vertical support plate 43, and a lifting block 39 for lifting is provided on the vertical support plate 43, and further includes:

[0042] The feeding mechanism is installed at the connection between the placement rack 3 and the support rack 2, and is used to push the stacked sheets 4 one by one for loading and feeding processing. The feeding mechanism includes a unloading push plate 9 and a unloading push rod 10 for feeding connection. The unloading push rod 10 is fixedly connected to the unloading push plate 9, and the unloading push plate 9 is connected to the bottom of the placement rack 3 through a conveyor belt 11.

[0043] Furthermore, the feeding mechanism also includes an active roller 12 and a driven roller 13 for driving the unloading push rod 10 to move linearly for feeding. The conveyor belt 11 is transmission-connected to the active roller 12 and the driven roller 13. The active roller 12 and the driven roller 13 are both rotationally connected to the fixed seat 6. The fixed seat 6 is fixedly connected to the support frame 2. The active roller 12 is fixedly connected to the output shaft of the first motor 14. The first motor 14 is fixedly installed inside the fixed seat 6. The placement frame 3 is fixedly installed on the fixed seat 6 through the first fixed plate 5.

[0044] Furthermore, a discharge chute 8 for discharging materials is provided on one side of the placement rack 3, and an L-shaped guide plate 7 is also provided on the placement rack 3, which is adapted to be slidably connected to the unloading push plate 9, and a support guide frame 56 for guiding and discharging materials is also provided on the fixed seat 6.

[0045] Preferably, when processing panel furniture, the stacked sheets 4 are placed on the placement rack 3. For subsequent clamping and flipping processing, the output shaft of the first motor 14 drives the active roller 12 to rotate, thereby driving the conveyor belt 11 to drive the unloading push rod 10 on the unloading push plate 9 to move under the relationship that the conveyor belt 11 is respectively connected to the active roller 12 and the driven roller 13. Therefore, under the limiting and guiding action of the L-shaped guide plate 7, the unloading push rod 10 on the unloading push plate 9 can be driven to push the bottom sheet 4 to move and discharge, so that the sheet 4 is linearly discharged one by one from the discharge trough 8 on the placement rack 3, and under the supporting and guiding action of the supporting guide frame 56, it is convenient to complete the subsequent clamping and positioning processing.

[0046] This method of discharging materials one by one shortens the discharging time of a single plate. Compared with the traditional batch discharging method, discharging materials one by one can better control the equipment movement, avoid unnecessary waiting and adjustments, and thus improve the overall utilization rate of the equipment. It not only reduces the production adjustment time, but also correspondingly improves the response speed of the production line, reduces production costs, and enhances the company's market competitiveness.

[0047] Example 2

[0048] like Figures 1 to 11 As shown, this embodiment, based on embodiment 1, further includes a clamping mechanism, which is installed at one side of the lifting block 39 and is used to clamp and position the sheet material 4 transported from one side of the placement rack 3. The clamping mechanism includes a clamping rod 15 and a docking rack 17 for clamping operations. The clamping rod 15 is movably installed on the docking rack 17, and a propulsion rod 25 for clamping drive is provided on the inner side of the docking rack 17.

[0049] Furthermore, the clamping mechanism also includes a first connecting rod 20, a second connecting rod 22 and a sliding sleeve 18 for driving the clamping rod 15 to perform a clamping connection. The sliding sleeve 18 is slidably connected to the propulsion rod 25. One end of the first connecting rod 20 is rotatably connected to the docking frame 17 through the second rotating shaft 21, and the other end of the first connecting rod 20 is rotatably connected to the sliding sleeve 18 through the first rotating shaft 19. One end of the second connecting rod 22 is rotatably connected to the clamping rod 15 through the third rotating shaft 23, and the other end of the second connecting rod 22 is rotatably connected to the sliding sleeve 18 through the fourth rotating shaft 24.

[0050] Furthermore, the clamping mechanism also includes an electric push rod 26 for driving the propulsion rod 25 to move forward, the propulsion rod 25 is fixedly connected to the piston rod of the electric push rod 26, the electric push rod 26 is fixedly installed on the docking frame 17, and the docking frame 17 is fixedly connected to the rotating main shaft 27 through the docking block 55, the clamping rod 15 is limitedly slidably connected to the docking frame 17, and one end of the clamping rod 15 is fixedly connected to the clamping plate 16 for clamping.

[0051] Preferably, in this embodiment, when the sheet material 4 is linearly discharged from the discharge trough 8 on the placement rack 3, the piston rod of the electric push rod 26 drives the propulsion rod 25 to propel and move. Since the propulsion rod 25 moves toward the direction close to the clamping rod 15, the sliding sleeve 18 is driven to move toward the center position of the propulsion rod 25 under the traction action of the second connecting rod 22 and the first connecting rod 20. At this time, the angle between the first connecting rod 20 and the second connecting rod 22 becomes larger, and the clamping plates 16 on the corresponding propulsion clamping rod 15 approach each other, thereby completing the clamping and positioning operation of the sheet material 4, thereby facilitating subsequent processing and flipping operations, without the need for manual intervention in the clamping process, and significantly improving work efficiency.

[0052] This clamping and positioning method can greatly shorten the clamping time of the plate. Compared with traditional bolt fixing or manual pressing methods, these automated clamping devices can achieve clamping in seconds, improve equipment utilization, shorten the processing cycle of a single plate, reduce the number of manual adjustments, and significantly reduce labor intensity, thereby further improving subsequent production and processing efficiency.

[0053] Example 3

[0054] like Figures 1 to 13As shown, this embodiment, based on the above embodiment, further includes a flipping mechanism, which is installed at the connection between the lifting block 39 and the vertical support plate 43, and is used to drive the sheet material 4 clamped by the clamping mechanism to perform a flipping operation. The flipping mechanism includes a rotating spindle 27, a rotating gear 50 and a second fixed plate 51 for driving the lifting block 39 to drive the sheet material 4 clamped by the clamping rod 15 to perform a flipping operation. One end of the rotating spindle 27 is fixedly connected to the rotating gear 50 and the rotating spindle 27 is rotatably connected to the lifting block 39. A step groove 52 is provided on one side of the second fixed plate 51, and the height of the step groove 52 is lower than that of the second fixed plate 51.

[0055] Furthermore, the flip mechanism also includes teeth 53 for driving the rotating main shaft 27 to rotate. There are several teeth 53 and they are all fixedly connected to the second fixed plate 51, and the rotating gear 50 is meshed with the teeth 53. The rotating main shaft 27 is fixedly connected to a limiting plate 33. A snap ring 34 is provided in the middle of the limiting plate 33. The snap ring 34 is sleeved on the rotating main shaft 27. The snap ring 34 is fixedly connected to one side of the traction plate 35. The traction plate 35 is slidingly connected to the lifting block 39. One side of the traction plate 35 is fixedly connected to a shift rod 36. The lifting block 39 is provided with a sliding groove 38 that is adapted for sliding connection with the shift rod 36. One end of the traction plate 35 is fixedly connected to a docking plate 37, and the rotating gear 50 is rotatably connected to the docking plate 37.

[0056] Furthermore, the flip mechanism also includes an elastic limiting rod 29 for elastically positioning the rotation of the rotating main shaft 27. The elastic limiting rod 29 is fixedly installed inside the lifting block 39. The rotating main shaft 27 is provided with a plurality of limiting grooves 28 that are adapted to connect with the elastic limiting rod 29. The elastic limiting rod 29 includes a fixed sleeve 30 and a limiting column 31. The limiting column 31 is slidingly connected to the fixed sleeve 30 for limiting movement. A spring 32 is provided at the connection between the limiting column 31 and the fixed sleeve 30.

[0057] Furthermore, the flip mechanism also includes a first shift plate 44 and a second shift plate 47 for driving the traction plate 35 to pull the rotating main shaft 27 for rotational switching. The first shift plate 44 and the second shift plate 47 are both fixedly mounted on the vertical support plate 43. The first shift plate 44 is provided with a first groove 45 that is adapted for sliding connection with the shift rod 36, and the first groove 45 is provided with a first bevel 46 for guiding. The second shift plate 47 is provided with a second groove 48 that is adapted for sliding connection with the shift rod 36, and the second groove 48 is provided with a second bevel 49 for guiding.

[0058] Furthermore, the flip mechanism also includes a dovetail slider 40 and a screw rod 41 for driving the lifting block 39 to perform linear lifting movement control. The lifting block 39 is fixedly connected to the dovetail slider 40, and the dovetail slider 40 is limitedly slidably connected to the vertical support plate 43, and the dovetail slider 40 is threadedly connected to the screw rod 41, and the screw rod 41 is rotatably connected to the vertical support plate 43. The screw rod 41 is fixedly connected to the output shaft of the second motor 42, and the second motor 42 is fixedly installed inside the base plate 1.

[0059] Preferably, in this embodiment, after the clamping and positioning of the sheet material 4 is completed, the visual inspection probe 54 on the vertical support plate 43 performs visual inspection to detect whether it needs corresponding flipping processing. When flipping processing is not required, the processing equipment on the side of the sheet material 4 (not shown in the figure) can perform corresponding processing.

[0060] When the sheet material 4 needs to be turned over, the output shaft of the second motor 42 drives the screw 41 to rotate, and the lifting block 39 drives the sheet material 4 clamped by the side of the rotating spindle 27 to move downward under the relationship between the dovetail slider 40 and the screw 41. Figure 1 and Figure 2 As shown, the rotating gear 50 is located at the positive side position of the step groove 52. When the lifting block 39 drives the shift rod 36 to move to the position of the first shift plate 44, due to the inclined setting of the first bevel 46, the shift rod 36 slides into the first groove 45. Then, under the inclined action of the first bevel 46, the shift rod 36 drives the clamping ring 34 on the side of the traction plate 35 to pull the rotating gear 50 on the rotating spindle 27 to move in the direction close to the second fixed plate 51. Then, the rotating gear 50 is moved to the positive side position of the second fixed plate 51. At this time, under the rotation of the screw rod 41 and the relationship of the threaded connection, the rotating gear 50 is driven The lifting block 39 drives the clamped sheet material 4 to move upward. When the rotating gear 50 on the rotating spindle 27 moves to the position where it is engaged with the teeth 53, the rotating spindle 27 can be driven accordingly to drive the clamped sheet material 4 to flip 180° under the relationship of the meshing connection of the teeth 53, thereby facilitating the flipping processing of the sheet material 4. At this time, the lever 36, under the action of the second bevel 49 and the second groove 48 set on the second shift plate 47, drives the rotating gear 50 on the rotating spindle 27 to move to the positive side position of the step groove 52 to facilitate subsequent flipping processing.

[0061] Among them, it should be particularly noted that the movement of the rotating gear 50 driven by the rotating spindle 27, and the rotation of the rotating gear 50 driven by the rotating spindle 27, are both elastically limited by the elastic limiting rod 29 and the limiting groove 28, and corresponding elastic limiting rods 29 are provided on both sides of the limiting groove 28 set on the rotating spindle 27 for elastic limiting. At the same time, the angle between the limiting groove 28 and the limiting groove 28 corresponding to one rotation thereof is 180°, that is, in order to better adapt to the positioning of the 180° processing of the sheet material 4 flipping, and the center distance between the limiting groove 28 and the limiting groove 28 on its side corresponds to the distance the rotating gear 50 moves from the center of the step groove 52 to the center position of the second fixed plate 51, thereby facilitating the corresponding card-jointing positioning processing and facilitating processing and use.

[0062] By combining the visual inspection probe 54 above the vertical support plate 43 to perform visual inspection, the flipping processing is completed, so that the flipping processing can be selectively carried out as needed. The operator does not need to manually carry heavy objects, the labor intensity is greatly reduced, the working environment is improved, and the risk of manual contact with high-speed running equipment is reduced, which improves production safety. There is no need for manual multiple clamping to complete the flipping processing of the sheet material 4, and the operation is simple and convenient for production use.

[0063] It should be noted that the output shaft of the second motor 42 can be driven in both forward and reverse directions.

[0064] It should be noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
