[0027] like Figures 1 to 10As shown, an automatic shoe sole polishing device includes a polishing machine 32, a polishing head 33, a frame 1, a robotic arm 31, a polishing conveyor line 5, a material guiding device 4, a material blocking device 80, a material clamping device 6, a positioning device 64, and a detection device. The polishing conveyor line 5 and the robotic arm 31 are mounted on top of the frame 1, with the robotic arm 31 located on one side of the polishing conveyor line 5. The polishing machine 32 is mounted on the robotic arm 31 and connected to the polishing head 33. The material guiding device 4, the material clamping device 6, and the positioning device 64 are all mounted on the polishing conveyor line 5 and arranged sequentially. The detection device and the material blocking device 80 are also mounted on the polishing conveyor line 5, with the material blocking device 80 located above the material guiding device 4. The detection device is used to detect the position of the shoe sole 9 and control the start and stop of the polishing conveyor line 5. After the sole 9 is sent to the grinding conveyor line 5, it moves along the grinding conveyor line 5 to the guiding device 4. The guiding device 4 guides the sole 9 so that it enters the clamping device 6 and abuts against the positioning device 64. Then the clamping device 6 clamps the sole 9. Then the robotic arm 31 drives the grinding machine 32 and the grinding head 33 to grind the sole 9. The overall automation level is high, the grinding quality is stable, and the grinding efficiency is high.

[0028] The detection device includes a first detection sensor 81, a second detection sensor 82, a third detection sensor 83, and a fourth detection sensor 84, all installed on the grinding conveyor line 5 and arranged sequentially. All detection sensors are photoelectric sensors. The first detection sensor 81 detects whether a shoe sole 9 has entered the conveyor.

[0029] The material guiding device 4 includes a material guiding connecting plate 42 and a material guiding baffle 41. The material guiding connecting plate 42 has a waist-shaped first adjustment groove 421 arranged along its length. The material guiding connecting plate 42 is mounted on the grinding conveyor line 5 by screws and is connected to the material guiding baffle 41. The material guiding baffle 41 has a waist-shaped second adjustment groove 412 and a detection groove 411 arranged along its length. The second adjustment groove 412 is connected to the first adjustment groove 421 by screws for easy position adjustment. The detection groove 411 is arranged opposite to the second detection sensor 82 to facilitate the second detection sensor 82 in detecting whether there is a shoe sole 9 in the material guiding device 4. The material guiding baffle 41 is arranged in a V-shape to facilitate the entry of the shoe sole 9 and to guide and correct its angle.

[0030] The material blocking device 80 includes a material blocking cylinder 801 and a material blocking plate 802. The material blocking cylinder 801 is installed on the grinding conveyor line 5 via a material blocking connecting plate 803. The material blocking plate 802 is installed on the material blocking cylinder 801 and is set horizontally. The material blocking cylinder 801 is a dual-shaft cylinder and is set vertically. The material blocking cylinder 801 drives the material blocking plate 802 to descend above the grinding conveyor line 5 to block the shoe soles 9, preventing multiple shoe soles 9 from entering the material guiding device 4 at the same time, and preventing blockage that would prevent the shoe soles 9 from being conveyed normally.

[0031] The clamping device 6 includes a fixed clamping device 61, a movable clamping device 62, and a pressing device 63. The fixed clamping device 61 and the pressing device 63 are both fixed on the frame 1. The fixed clamping device 61 is equipped with two first elastic devices 7, and the movable clamping device 62 is equipped with two second elastic devices 70. The second elastic devices 70 are arranged opposite to the first elastic devices 7 and are located on both sides of the shoe sole 9. The movable clamping device 62 is connected to the pressing device 63, and the pressing device 63 is used to drive the second elastic devices 70 to press the shoe sole 9 onto the first elastic devices 7.

[0032] The structure of the first elastic device 7 is the same as that of the second elastic device 70. The first elastic device 7 includes a first elastic seat 71, a first guide seat 72, a first elastic pressure rod 73, and a first spring. The first elastic seat 71 is a rectangular seat with a first sliding groove 711 inside. The first sliding groove 711 is a rectangular groove. The first guide seat 72 is fixed to one end of the first elastic seat 71 by screws. A plurality of first guide holes 721 are arranged in an array on the first guide seat 72. A plurality of first elastic pressure rods 73 are arranged in an array in multiple rows, with the upper and lower rows of first elastic pressure rods 73 staggered. One end is arc-shaped, and the other end is provided with a first guide rod 733. The end of the first guide rod 733 is provided with a first limiting ring 734. The first guide rod 733 is movably inserted into the first guide hole 721 and corresponds one-to-one with the first guide hole 721. The first elastic pressure rod 73 and the first limiting ring 734 are respectively located at both ends of the first guide seat 72. The first spring is movably inserted on the first guide rod 733, and its two ends abut against the first elastic pressure rod 73 and the first guide seat 72 respectively. The first spring keeps the first elastic pressure rod 73 in a state of extending out of the first elastic seat 71 and corresponds one-to-one with the first elastic pressure rod 73.

[0033] The first guide seat 72 can also be equipped with partition plates 78 at both ends. The partition plates 78 are provided with several rows of waist-shaped limiting through holes. The first guide rod 733 is movably inserted into the limiting through holes, and the diameter of the first limiting ring 734 is larger than the diameter of the limiting through holes. The partition plates can be made of rubber plates for shock absorption.

[0034] To better guide the first elastic pressure rod 73 to move axially, the system also includes a first upper limit seat 74 and a first side limit seat 75. The top and one side of the first elastic seat 71 are respectively provided with a first upper mounting groove 712 and a first side mounting groove 713, both of which communicate with the first sliding groove 711. The first upper limit seat 74 has an array of several first upper guide grooves 741, which are arc-shaped grooves that match the first elastic pressure rods 73. The first upper limit seat 74 is installed within the first upper mounting groove 712, and the first elastic pressure rods 73 in the top row of the first sliding groove 711 are movably inserted into the first upper guide grooves 741. The first upper limit seat 74 guides the top row of first elastic pressure rods 73, improving the stability of the first elastic pressure rods 73 moving axially, preventing lateral swaying, facilitating the installation of the first elastic pressure rods 73, and reducing the machining precision required for the first sliding groove 711. A plurality of first side guide grooves 752 and first side guide blocks 751 are arranged in a sequential array on the first side limiting seat 75. The first side limiting seat 75 is installed in the first side mounting groove 713. The first elastic pressure rods 73 located on one side of the first sliding groove 711 are all movably inserted into the first side guide grooves 752 and the first side guide blocks 751. The first side limiting seat 75 restricts the position of the first elastic pressure rods 73 from the side, improves the stability of the axial movement of the first elastic pressure rods 73, and reduces the machining accuracy requirements in the width direction of the first sliding groove 711. This allows the width of the first sliding groove 711 to be reduced, and facilitates the separate clamping of the staggered first elastic pressure rods 73.

[0035] The top of the first elastic seat 71 is equipped with a first upper fixing block 77, which is also located above the first upper mounting groove 712 and is used to position the first upper limit seat 74. The side of the first elastic seat 71 is equipped with a first side fixing block 76, which is also located above the first side mounting groove 713 and is used to fix the first side limit seat 75.

[0036] The fixing clamping device 61 also includes a fixing base plate 611 and a fixing connecting plate 612. The fixing base plate 611 is installed on the top of the frame 1 and is connected to the fixing connecting plate 612 by screws. The fixing connecting plate 612 is connected to the first upper fixing block 77 by screws, thereby fixing the first elastic device 7. The structure is simple and easy to install.

[0037] The movable clamping device 62 includes a movable connecting plate 621 and a movable seat 622. The movable connecting plate 621 is connected to the second elastic device 70 by screws, and the movable seat 622 is connected to the movable connecting plate 621. The movable seat 622 is provided with a pressing groove 623, which is arranged opposite to the second elastic device 70 and is used to accommodate the second elastic pressure rod that moves backward.

[0038] The clamping device 63 uses a clamping cylinder, which is a three-axis cylinder or a two-axis cylinder. The piston rod end of the clamping cylinder is connected to the movable seat 622 to drive the second elastic device 70 to move.

[0039] To facilitate positioning of the sole 9 between the fixed clamping device 61 and the movable clamping device 62, a positioning device 64 is also included. The positioning device 64 includes a positioning cylinder 641 and a positioning baffle 642. The positioning cylinder 641 is a three-axis cylinder, fixed to the top of the frame 1 and connected to the positioning baffle 642. A third detection sensor 83 is installed on the top of the frame 1, located between the fixed clamping device 61 and the positioning cylinder 641.

[0040] The fixed clamping device 61 and the movable clamping device 62 are located on both sides of the conveyor line, which is mounted on the frame 1. When the sole 9 moves toward the fixed clamping device 61 under the drive of the conveyor line, and the positioning sensor 83 detects the sole 9, the positioning cylinder 641 drives the positioning baffle 642 to move between the fixed clamping device 61 and the movable clamping device 62, and sets it opposite to the sole 9. Then, the pressing cylinder drives the second elastic device 70 to move toward the first elastic device 7. The second elastic pressure rod presses the sole 9 onto the first elastic pressure rod 73. Since there are several of the first elastic pressure rod 73 and the second elastic pressure rod, they can fit well against the contour line of the sole 9 and press the sole 9 tightly. At the same time, since springs are used for pressing, the force of the springs can be controlled. The force of each spring is small. When several springs press at the same time, reliable pressing can be ensured so that the sole 9 will not loosen, and deformation of the sole 9 can be avoided, thus ensuring the polishing quality. After grinding is completed, the clamping cylinder drives the second elastic pressure rod to retract, and the second elastic pressure rod and the first elastic pressure rod 73 are reset under the action of the spring.

[0041] During operation, when the shoe sole 9 enters the grinding conveyor line 5, the first detection sensor 81 detects the shoe sole 9, the blocking cylinder 801 is in the retracted state, the grinding conveyor line 5 drives the shoe sole 9 to move towards the guide device 4, and the shoe sole 9 moves towards the clamping device 6 under the action of the two guide baffles 41. The second detection sensor 82 detects the shoe sole 9, indicating that the shoe sole 9 has completely entered the guide baffle 41. When the first detection sensor 81 detects a new shoe sole 9 again, the blocking cylinder 801 is in the extended state, and the blocking cylinder 801 drives the baffle plate 802 to descend onto the grinding conveyor line 5. The new sole 9 is blocked. When the third detection sensor 83 detects the sole 9, the positioning cylinder 641 moves the positioning baffle 642 between the fixed clamping device 61 and the movable clamping device 62, and sets it opposite to the sole 9. Then, the clamping cylinder of the pressing device 63 moves the second elastic device 70 towards the first elastic device 7. The second elastic rod of the second elastic device 70 presses the sole 9 against the first elastic rod 73, the grinding conveyor line 5 stops, and then the robotic arm 31 drives the grinding head 33 to perform grinding. The grinding trajectory is set in advance according to the required shape. After grinding is completed, the clamping device 63 releases the sole 9, the positioning cylinder 641 moves the positioning baffle 642 back to one side of the grinding conveyor line 5, the grinding conveyor line 5 starts, and the sole 9 moves towards the discharge end of the grinding conveyor line 5. When the fourth detection sensor 84 detects the sole 9, the blocking cylinder 801 rises and releases the sole 9 to be ground.
