[0003] The two opposite sides of the existing workpiece are roughly vertical planes. The sanding belt edge grinding device needs to grind one of the vertical planes of the workpiece. After the edge grinding is completed, it is necessary to manually transfer it to the sanding belt chamfering device to chamfer the ground surface of the workpiece.

[0004] The existing sanding belt edge grinding device and sanding belt chamfering device need to manually fix the workpiece on a specific carrier during grinding, and make the side of the workpiece to be ground face the device, and grind one side of the workpiece by rotating the sanding belt paper in the device. After grinding, the workpiece needs to be manually removed, and then the uniformly edged workpieces are collected and manually transferred to the sanding belt chamfering device, and the edged surface of the workpiece is chamfered through the same operation.

The clamping positioning platform 43 is fixedly connected to the moving part 421 of the clamping electric cylinder 42 in the horizontal direction; the pressing plate 44 is connected to the clamping positioning platform 43 in a horizontal sliding manner through the clamping horizontal slide rail 46; the pressing plate 44 can ensure that the workpiece 1 is prevented from directly and rigidly contacting the sandpaper during the clamping process through the sliding connection, and can provide a certain buffer sliding effect to the workpiece 1, preventing the workpiece 1 from directly contacting the rapidly rotating sandpaper, ensuring that the workpiece 1 is slowly pressed against the sandpaper for grinding, preventing the workpiece 1 from being damaged by grinding, and ensuring the grinding accuracy, and making the overall structure more concise and reasonable. The clamping limit part 45 is arranged on the side of the clamping positioning platform 43 away from the conveyor belt mechanism, and the clamping limit part 45 is used to block the clamping plate 44 during edge grinding. In this embodiment, the clamping limit part 45 is a wire pressing limit block, and the wire pressing limit block is provided with left and right clamping limit columns to achieve limit. A plurality of spaced and flush pressing guide wheels 47 are arranged on the side of the pressing plate 44 close to the conveyor belt mechanism, and each pressing guide wheel 47 is vertically distributed. The pressing electric cylinder 42 in the pressing assembly drives the pressing plate 44 on the pressing positioning platform 43 to press against the workpiece 1, and can press the workpiece 1 against the sandpaper, and the pressing guide wheel 47 can realize grinding while ensuring that the workpiece 1 continues to be conveyed to the discharge end, greatly improving the grinding efficiency, and can also be conveyed to a designated position, stop to grind the workpiece, and then convey it.

[0043] like Figure 6 As shown, a gap baffle 48 is also provided between two adjacent pressing guide wheels 47 on the pressing plate 44; the gap baffle 48 is used to prevent the workpiece 1 from getting stuck in the gap between the two pressing guide wheels 47; the gap baffle 48 can prevent one end of the workpiece 1 from getting stuck in the gap between two adjacent pressing guide wheels 47 during pressing and grinding, ensuring that the workpiece 1 is transported and ground horizontally and smoothly, and ensuring the grinding effect. All the gap baffles 48 are on the same plane, and the gap baffles 48 are located on the inner side of the contact end of the pressing guide wheel 47. Being on the same plane can ensure the flatness between the gap baffles 48, and also ensure that the workpiece 1 is in contact with the pressing guide wheel 47, ensuring the stability during transportation and the accuracy of grinding.

[0044] When the device is working, the workpiece 1 is transported to the conveyor belt 21 of the first edging device manually or by a robot, and the conveyor belt motor 222 on the edging conveyor belt mechanism 2 drives the active roller 223 of the conveyor belt to rotate, and the conveyor belt 21 is circulated with the cooperation of the driven roller 224 of the conveyor belt, so that the workpiece 1 on the conveyor belt 21 is transported to the discharge end, and transported to between the sanding belt edging component 3 and the sanding pressing component 4 of the first edging component, and the positioning motor 37 in the edging positioning unit on the sanding belt edging component 3 drives the positioning screw 38 to rotate, and then cooperates with the positioning slider to drive the edging drive unit on the positioning slide 39 to gradually approach the conveyor belt 21 until it moves to the specified position. After edging positioning, the driving motor 32 on the edging drive unit drives the active roller 33 to rotate, and the driven roller 3 4, the edge grinding abrasive belt paper 30 is circulated and rotated in a circular manner, and the edge grinding in the thickness direction is performed after the workpiece 1 is pressed. When the abrasive belt grinding assembly 3 is in action, the edge grinding pressing assembly 4 drives the pressing plate 44 on the pressing positioning platform 43 to press against the workpiece 1 through the pressing electric cylinder 42, so that the pressing guide wheel 47 on the pressing plate 44 presses the workpiece 1 against the edge grinding abrasive belt paper 30 of the abrasive belt grinding assembly 3. When the workpiece 1 contacts the edge grinding abrasive belt paper 30, the pressing plate 44 is continuously pushed forward, so that the pressing plate 44 slides on the pressing positioning platform 43 until it is stopped on the pressing limit portion 45, thereby ensuring that the workpiece 1 is pressed between the pressing guide wheel 47 and the edge grinding abrasive belt paper 30, and the edge grinding of one side of the workpiece 1 in the thickness direction is performed by the rotation of the edge grinding abrasive belt paper 30. The workpiece 1 is transported along the conveyor belt 21, and the pressing and edging is also completed during transportation, thereby greatly improving the edging efficiency. After the edging is completed, the belt edging assembly 3 and the edging clamping assembly 4 are moved to both sides respectively, and the conveyor belt 21 continues to convey the workpiece 1 to between the belt edging assembly 3 and the edging clamping assembly 4 of the second edging assembly, and the other side surface of the workpiece 1 in the thickness direction is edged by the same action, finally realizing the edging processing of the two side surfaces in the thickness direction of the workpiece 1.

[0045] After the edging in the thickness direction is completed, the workpiece 1 is rotated horizontally by rotating the manipulator, and the edging processing of the two side surfaces in the width direction of the workpiece 1 is achieved through the same edging method mentioned above. After the edging in the width direction is completed, the workpiece 1 is rotated vertically by rotating the manipulator, and the edging processing of the two side surfaces in the length direction of the workpiece 1 is achieved through the same edging method mentioned above. Finally, it is sent to the abrasive belt chamfering assembly 6 and the chamfering pressing assembly 7 for quality inspection through the conveyor belt 21. The chamfering processing is achieved by pressing the workpiece 1 against the inclined surface 601 of the chamfering abrasive belt paper 60, and four chamfering processes are completed four times through four chamfering mechanisms to achieve chamfering processing at two angles on the two side surfaces in the length direction of the workpiece 1.

[0046] Embodiment 2 like Figures 2 to 10As shown, compared with the first embodiment, the second embodiment is different in the position sequence of the chamfering device, which is moved from the last station to the second station, first grinding and chamfering in the length direction, then in the width direction, and finally in the thickness direction. The structures and working methods of grinding and chamfering are the same.

[0047] Embodiment 3 like Figures 2 to 9 as well as Fig.11 As shown, compared with the first embodiment, the third embodiment has one more chamfering device and one less grinding device, and the position sequence is different, first grinding and chamfering in length, then grinding and chamfering in width. The structures and working methods of grinding and chamfering are the same.

[0048] The present invention only cites three embodiments of the present invention. In actual application, different embodiments can be arranged and combined according to the actual situation, which will not be described in detail here.

The edge grinding mechanism presses the workpiece 1 to the sanding belt edge grinding component 3 on the other side through the edge grinding clamping component 4 to realize edge grinding; the chamfering mechanism presses the workpiece 1 to the sanding belt chamfering component 6 on the other side through the chamfering clamping component 7 to realize chamfering; there is no need for manual clamping of the workpiece 1 during the processing, and it is also convenient to complete the grinding work during the transportation process, which greatly improves the fluency and connectivity of the entire equipment, and also improves the convenience of grinding, ultimately ensuring the grinding accuracy while greatly improving the overall processing efficiency.
