[0050] In order to solve the technical problems of limited edge grinding angle and deviation in adjusting the edge grinding angle, as Figure 1 shown in and Figure 11, the following technical solutions are provided:

[0051] An edge grinding device, comprising:

[0052] A workbench 1, the workbench 1 is a rectangular workbench 1;

[0053] A positioning mechanism 2, the positioning mechanism 2 is located on the workbench 1, and the positioning mechanism 2 is used to clamp the single-chip microcomputer on the positioning mechanism 2 so that the single-chip microcomputer cannot move;

[0054] A material transfer mechanism 3, which is used to transfer the single-chip microcomputer to the positioning mechanism 2 and then remove the single-chip microcomputer from the positioning mechanism 2 after the edge grinding is completed;

[0055] An edge grinding mechanism 4, which is located on the workbench 1 and is used to grind the edge of the single-chip microcomputer;

[0056] An adjusting mechanism 5, which is used to adjust the angle of the single-chip microcomputer ground by the edge grinding mechanism 4;

[0057] A displacement mechanism 6, which is located at one end of the workbench 1 in the width direction and is used to drive the edge grinding mechanism 4 and the adjusting mechanism 5 to move in the length and width directions of the workbench 1;

[0058] The adjusting mechanism 5 includes:

[0059] A mounting frame 5a, which is vertically fixed to the displacement mechanism 6, and a rotating shaft 5a1 is provided on the mounting frame 5a;

[0060] An adjusting component 5b, which is located on the mounting frame 5a and is used to adjust the angle of the single-chip microcomputer ground by the edge grinding mechanism 4;

[0061] A linear driver 5c, which is located beside the adjusting component 5b and is used to drive the adjusting component 5b to adjust the edge grinding angle of the single-chip microcomputer by the edge grinding mechanism 4;

[0062] A limiting component 5d, which is located on the side of the adjusting component 5b away from the linear driver 5c and is used to fix the adjusting component 5b through the limiting component 5d after the edge grinding angle is adjusted by the adjusting component 5b to prevent the edge grinding angle from shifting.

[0063] First, place the single-chip microcomputer on the positioning mechanism 2 through the material transfer mechanism 3, drive the mounting frame 5a to move in the length and width directions of the workbench 1 by starting the displacement mechanism 6, thereby driving the movement of the edge grinding mechanism 4 and the adjusting mechanism 5, drive the adjusting component 5b to adjust the edge grinding angle of the single-chip microcomputer by the edge grinding mechanism 4 through the linear driver 5c, and then fix the adjusting component 5b through the limiting component 5d to prevent the edge grinding angle from shifting. Then, use the edge grinding mechanism 4 to grind the edge of the single-chip microcomputer. Finally, when the edge grinding is completed, remove the single-chip microcomputer from the positioning mechanism 2 through the material transfer device.

[0064] To solve the technical problem of single-chip microcomputer material transfer, as Figure 2 shown, the following technical solutions are provided:

[0065] The material transfer mechanism 3 includes a material transfer manipulator 3a, a first conveyor belt 3b and a second conveyor belt 3c. The first conveyor belt 3b and the second conveyor belt 3c are respectively located on the sides of both ends in the width direction of the workbench 1, and the material transfer manipulator 3a is located on the workbench 1 and between the first conveyor belt 3b and the second conveyor belt 3c.

[0066] First, the first conveyor belt 3b is used to transfer the single-chip microcomputer to the side of the grinding device. Then, the material transfer manipulator 3a places the single-chip microcomputer on the positioning mechanism 2. After the edge of the single-chip microcomputer is ground by the grinding device, the material transfer manipulator 3a removes the single-chip microcomputer from the positioning mechanism 2 and places it on the second conveyor belt 3c. The second conveyor belt 3c is used to transfer the single-chip microcomputer with the edge grinding completed out of the device.

[0067] To solve the technical problem of fixing the single-chip microcomputer, such as Figure 3 as shown, the following technical solutions are provided:

[0068] The positioning mechanism 2 is located between the material transfer mechanism 3 and the edge grinding mechanism 4. There is at least one positioning mechanism. The positioning mechanism 2 includes a bracket 2a, a positioning seat 2b and two clamping plates 2c. The bracket 2a is fixedly connected to the workbench 1 in a vertical state. The positioning seat 2b is fixedly connected to the top of the bracket 2a in a horizontal state. The two clamping plates 2c are respectively located on the inner walls at both ends in the length direction of the positioning seat 2b. The two clamping plates 2c are connected to the inner wall of the positioning seat 2b through electromagnetic springs 2d.

[0069] The initial positions of the two clamping plates 2c are attached to the inner walls at both ends in the length direction of the positioning seat 2b. When the material transfer manipulator 3a places the single-chip microcomputer from the first conveyor belt 3b on the positioning seat 2b, by starting the power supply, the electromagnetic springs 2d at both ends of the positioning seat 2b are powered off, and the electromagnetic springs 2d eject, so that the two clamping plates 2c connected to the electromagnetic springs 2d clamp simultaneously towards the center of the positioning seat 2b until the two clamping plates 2c clamp the single-chip microcomputer so that the single-chip microcomputer cannot move. Wait for the adjustment mechanism 5 to grind the single-chip microcomputer. When the grinding is completed, by energizing, the electromagnetic springs 2d on both sides of the positioning seat 2b return to the initial position, so that the clamping plates 2c lose the clamping force on the single-chip microcomputer, and then the material transfer manipulator 3a removes the single-chip microcomputer and places it on the second conveyor belt 3c.

[0070] To solve the technical problem of edge grinding of the single-chip microcomputer, such as Figures 4 - 8 as shown, the following technical solutions are provided:

[0071] The edge grinding mechanism 4 includes a connecting arm 4a, a first motor 4b, a synchronous belt 4c, a driving shaft 4d, a driven shaft 4e, a grinding wheel 4f, a dust-proof assembly 4g, and a housing 4h. The connecting arm 4a is fixedly connected to the adjusting assembly 5b. The driving shaft 4d and the driven shaft 4e are respectively sleeved at two ends of the connecting arm 4a. The driving shaft 4d is located at one end of the connecting arm 4a close to the adjusting assembly 5b, and the driven shaft 4e is located at the other end of the connecting arm 4a. The driving shaft 4d and the driven shaft 4e are connected by the synchronous belt 4c. A housing 4h that matches the connecting arm 4a is sleeved outside the connecting arm 4a. A first motor 4b is fixedly connected to the outer side wall of the housing 4h. The output shaft of the first motor 4b penetrates through the side wall of the housing 4h and is fixedly connected to the driving shaft 4d. The grinding wheel 4f is sleeved on the driven shaft 4e, and a dust-proof assembly 4g is also sleeved on the driven shaft 4e.

[0072] By starting the first motor 4b, the output shaft of the first motor 4b drives the rotation of the driving shaft 4d fixedly connected thereto. The rotation of the driving shaft 4d drives the rotation of the driven shaft 4e connected thereto through the synchronous belt 4c. The rotation of the driven shaft 4e drives the rotation of the grinding wheel 4f connected thereto, thereby solving the technical problem of edge grinding the single-chip microcomputer.

[0073] To solve the technical problem of collecting edge grinding powder chips, as Figures 5 - 7 shown, the following technical solutions are provided:

[0074] The dust-proof assembly 4g includes a dust-proof cover 4g1, an air pipe 4g2, and a dust suction box 4g3. The dust-proof cover 4g1 is sleeved on the driven shaft 4e. The dust-proof cover 4g1 matches the grinding wheel 4f. The air pipe 4g2 is located at the bottom of the dust-proof cover 4g1. The dust suction box 4g3 is located below the dust-proof cover 4g1 and is fixedly connected to the workbench 1. The dust suction box 4g3 is connected to the dust-proof cover 4g1 through the air pipe 4g2.

[0075] By starting the dust suction box 4g3, the dust suction box 4g3 forms a negative pressure in the dust-proof cover 4g1 through the air pipe 4g2. When the edge grinding assembly grinds the single-chip microcomputer, the grinding wheel 4f rotates to bring the dust generated during the edge grinding process into the dust-proof cover 4g1. Due to the negative pressure in the dust-proof cover 4g1, the dust is adsorbed into the dust suction box 4g3 through the air pipe 4g2, thereby keeping the workbench 1 clean and preventing the powder chips generated during the edge grinding process from being inhaled by the staff into the body.

[0076] To solve the technical problem of adjusting the edge grinding angle, as Figure 9 、 Figure 10 and Figure 13 shown, the following technical solutions are provided:

[0077] The adjusting assembly 5b includes a gear 5b1, a turntable 5b3 and a rack 5b2. The gear 5b1 is sleeved on the rotating shaft 5a1 of the mounting bracket 5a. The turntable 5b3 is fixedly connected to the gear 5b1. The turntable 5b3 is fixedly connected to one end of the connecting arm 4a where the driving shaft 4d is installed. The rack 5b2 is vertically fixedly connected to the mounting bracket 5a and is located beside the gear 5b1. The rack 5b2 and the gear 5b1 are meshed and connected. One side of the rack 5b2 close to the mounting bracket 5a is provided with a first slide bar which is matched with the linear actuator 5c, and the rack 5b2 is in transmission connection with the linear actuator 5c.

[0078] The linear actuator 5c drives the linear movement of the rack 5b2. The movement of the rack 5b2 drives the rotation of the gear 5b1 meshed with it. The rotation of the gear 5b1 drives the rotation of the turntable 5b3 fixedly connected to it. The rotation of the turntable 5b3 drives the rotation of the connecting arm 4a fixedly connected to it. Thus, the edging mechanism 4 can rotate 0 - 180 degrees with the gear 5b1 as the center point. By adjusting the stroke distance of the linear actuator 5c, the movement distance of the rack 5b2 can be adjusted, and thus any angle within 0 - 180 degrees can be adjusted for the edging mechanism 4.

[0079] To solve the technical problems of the drive adjusting assembly, as Figure 9 、 Figure 10 and Figure 13 shown, the following technical solutions are provided:

[0080] The linear actuator 5c includes a second air cylinder 5c1, a push plate 5c2 and a sliding seat 5c3. The sliding seat 5c3 is vertically located on the side of the gear 5b1 away from the edging mechanism 4. The sliding seat 5c3 is provided with a slide rail which is matched with the slide bar of the rack 5b2 and is slidably connected to it. The second air cylinder 5c1 is vertically located beside the rack 5b2 and its output shaft is placed upward. The push plate 5c2 is located at the top of the second air cylinder 5c1. Both ends of the push plate 5c2 are fixedly connected to the output shaft of the second air cylinder 5c1 and the top end of the rack 5b2 respectively.

[0081] When the adjusting assembly 5b needs to adjust the angle of edging, the second air cylinder 5c1 is started. The output shaft of the second air cylinder 5c1 extends and drives the push plate 5c2 fixedly connected to it. The movement of the push plate 5c2 drives the movement of the rack 5b2 fixedly connected to its other end. The rack 5b2 moves along the slide rail on the sliding seat 5c3 through the slide bar, thereby driving the stable movement of the rack 5b2. By controlling the stroke distance of the output shaft of the second air cylinder 5c1, the movement distance of the rack 5b2 can be adjusted, and the rotation of the gear 5b1 can be realized, so as to adjust the edging angle of the edging mechanism 4.

[0082] To solve the technical problem of a fixed edging angle, such as Figure 9 , Figure 10 and Figure 13 shown, the following technical solutions are provided:

[0083] The limit component 5d includes a mounting base 5d1, a first cylinder 5d2, and a fixed tooth 5d3. The mounting base 5d1 is vertically fixed to the mounting frame 5a and is located above the gear 5b1. The first cylinder 5d2 is vertically fixed to the mounting base 5d1 and its output shaft is placed downward. The fixed tooth 5d3 is fixedly connected to the output shaft of the first cylinder 5d2, and the fixed tooth 5d3 matches the gear 5b1.

[0084] After the adjustment component 5b adjusts the edging angle of the edging mechanism 4, the gear 5b1 stops rotating. At this time, the first cylinder 5d2 is activated, and the output shaft of the first cylinder 5d2 extends to drive the movement of the fixed tooth 5d3 fixedly connected thereto. The movement of the fixed tooth 5d3 causes its teeth to insert into the gear 5b1, making the gear 5b1 unable to rotate, so that the edging angle of the edging mechanism 4 cannot shift during the edging process.

[0085] To solve the technical problems of a movable edging mechanism and an adjustment mechanism, such as Figure 12 and Figure 14 shown, the following technical solutions are provided:

[0086] The displacement mechanism 6 includes a first translation component 6a and a second translation component 6b. The first translation component 6a includes a lead screw 6a1, a second motor 6a2, a displacement frame 6a4, a slide table 6a6, two guide columns 6a3, and two mounting plates 6a5. The displacement frame 6a4 is horizontally placed at one end in the width direction of the workbench 1. The two mounting plates 6a5 are respectively located at both ends of the displacement frame 6a4. The slide table 6a6 is located on the displacement frame 6a4. The lead screw 6a1 and the two guide columns 6a3 pass through the slide table 6a6 and are connected between the two mounting plates 6a5. The slide table 6a6 is in threaded cooperation with the lead screw 6a1. The two guide columns 6a3 are located on both sides of the lead screw 6a1. The lead screw 6a1 and the two guide columns 6a3 are parallel to each other. The second motor 6a2 is located on the mounting plate 6a5 at one end of the displacement frame 6a4. The output shaft of the second motor 6a2 passes through the mounting plate 6a5 and is fixedly connected to the lead screw 6a1. The structures of the first translation component 6a and the second translation component 6b are exactly the same. The second translation component 6b is perpendicular to the first translation component 6a. The bottom of the second translation component 6b is fixedly connected to the slide table 6a6 of the first translation component 6a. The mounting frame 5a of the adjustment mechanism 5 is fixedly connected to the slide table 6a6 of the second translation component 6b.

[0087] After the edge grinding mechanism 4 adjusts the edge grinding angle through the adjusting mechanism 5, by starting the second motor 6a2 of the first translation component 6a, the rotation of the output shaft of the second motor 6a2 drives the rotation of the lead screw 6a1 fixedly connected thereto. The rotation of the lead screw 6a1 drives the slide table 6a6 in threaded cooperation therewith to move on the displacement frame 6a4 along the direction of the two guide columns 6a3, thereby driving the second translation component 6b to move in the width direction on the workbench 1, and thus driving the edge grinding mechanism 4 and the adjusting mechanism 5 to move in the width direction of the workbench 1. Since the second translation component 6b is perpendicular to the first translation component 6a, the edge grinding mechanism 4 and the adjusting mechanism 5 can be moved in the length direction of the workbench 1. Through the cooperation of the first translation component 6a and the second translation component 6b, the edge grinding mechanism 4 and the adjusting mechanism 5 can be moved in the length direction and the width direction of the workbench 1 to reach the position required by the edge grinding mechanism 4.

[0088] Working principle of the present invention:

[0089] First, the first conveyor belt 3b is used to convey the single-chip microcomputer to the side of the grinding device, and then the transfer manipulator 3a places the single-chip microcomputer on the positioning mechanism 2.

[0090] Further, the initial positions of the two clamping plates 2c of the positioning mechanism 2 are attached to the inner walls at both ends in the length direction of the positioning seat 2b. After the transfer manipulator 3a places the single-chip microcomputer from the first conveyor belt 3b on the positioning seat 2b, by starting the power supply, the electromagnetic springs 2d at both ends of the positioning seat 2b are de-energized, and the electromagnetic springs 2d eject, so that the two clamping plates 2c connected to the electromagnetic springs 2d are simultaneously clamped towards the center of the positioning seat 2b until the two clamping plates 2c clamp the single-chip microcomputer so that the single-chip microcomputer cannot move, and then wait for the adjusting mechanism 5 to grind the single-chip microcomputer.

[0091] Further, the linear actuator 5c drives the rack 5b2 to move linearly. The movement of the rack 5b2 drives the rotation of the gear 5b1 meshed therewith. The rotation of the gear 5b1 drives the rotation of the turntable 5b3 fixedly connected thereto. The rotation of the turntable 5b3 drives the rotation of the connecting arm 4a fixedly connected thereto, so that the edge grinding mechanism 4 can rotate 0-180 degrees with the gear 5b1 as the center point. By adjusting the stroke distance of the linear actuator 5c, the movement distance of the rack 5b2 can be adjusted, and thus any angle within 0-180 degrees can be adjusted for the edge grinding mechanism 4.

[0092] When the adjusting component 5b needs to adjust the angle of the edge grinding, the second cylinder 5c1 is activated. The output shaft of the second cylinder 5c1 extends to drive the push plate 5c2 fixedly connected thereto. The movement of the push plate 5c2 drives the movement of the rack 5b2 fixedly connected to the other end thereof. The rack 5b2 moves along the slide rail on the sliding seat 5c3 through the slide bar, thereby driving the stable movement of the rack 5b2. By controlling the stroke distance of the output shaft of the second cylinder 5c1, the movement distance of the rack 5b2 can be adjusted, and the rotation of the gear 5b1 can be realized, thereby adjusting the edge grinding angle of the edge grinding mechanism 4;

[0093] Furthermore, after the adjusting component 5b adjusts the edge grinding angle of the edge grinding mechanism 4, the gear 5b1 stops rotating. At this time, the first cylinder 5d2 is activated. The output shaft of the first cylinder 5d2 extends to drive the movement of the fixed tooth 5d3 fixedly connected thereto. The movement of the fixed tooth 5d3 causes its teeth to insert into the gear 5b1, making the gear 5b1 unable to rotate, so that the edge grinding angle of the edge grinding mechanism 4 cannot shift during the edge grinding process;

[0094] Furthermore, by starting the first motor 4b, the output shaft of the first motor 4b drives the rotation of the driving shaft 4d fixedly connected thereto. The rotation of the driving shaft 4d drives the rotation of the driven shaft 4e connected thereto through the synchronous belt 4c. The rotation of the driven shaft 4e drives the rotation of the grinding wheel 4f connected thereto, thereby realizing the edge grinding of the single-chip microcomputer;

[0095] Furthermore, by starting the dust suction box 4g3, the dust suction box 4g3 forms a negative pressure in the dust-proof cover 4g1 through the air pipe 4g2. When the edge grinding component grinds the single-chip microcomputer, the grinding wheel 4f rotates to bring the dust generated during the edge grinding process into the dust-proof cover 4g1. Due to the negative pressure in the dust-proof cover 4g1, the dust is adsorbed into the dust suction box 4g3 through the air pipe 4g2, thereby keeping the workbench 1 clean. At the same time, the powder generated during the edge grinding process will not be inhaled by the staff into the body;

[0096] Further, after the edging mechanism 4 adjusts the edging angle through the adjusting mechanism 5, by starting the second motor 6a2 of the first translation assembly 6a, the rotation of the output shaft of the second motor 6a2 drives the rotation of the lead screw 6a1 fixedly connected thereto. The rotation of the lead screw 6a1 drives the slide table 6a6 in threaded cooperation therewith to move on the displacement frame 6a4 along the direction of the two guide columns 6a3, thereby driving the second translation assembly 6b to move in the width direction on the workbench 1, and thus driving the edging mechanism 4 and the adjusting mechanism 5 to move in the width direction on the workbench 1. Since the second translation assembly 6b is perpendicular to the first translation assembly 6a, the edging mechanism 4 and the adjusting mechanism 5 can be moved in the length direction of the workbench 1. Through the cooperation of the first translation assembly 6a and the second translation assembly 6b, the edging mechanism 4 and the adjusting mechanism 5 can be moved in the length direction and the width direction on the workbench 1 to reach the position required by the edging mechanism 4;

[0097] After the final polishing is completed, the electromagnetic springs 2d on both sides of the energized positioning seat 2b return to the initial position, so that the clamping plate 2c loses the clamping force on the single-chip microcomputer. Then, the single-chip microcomputer is removed by the material transfer manipulator 3a and placed on the second conveyor belt 3c and removed.
