Description

Technical Field

[0001] The invention relates to the technical field of industrial automation equipment, and in particular to an automatic loading and unloading manipulator for short-shaft parts. Background Art

[0002] Nowadays, automatic loading and unloading manipulators have become an indispensable part of automated production lines. They are easy to operate and highly efficient, and can save operators from heavy and monotonous working environments. The structure of automatic loading and unloading manipulators is also very different for different working environments. In some working environments that require a simpler motion path, the structure of the manipulator is often not too complicated; while for some working environments with more complex motion paths, the manipulator is required to have a higher degree of freedom, and the number of actuators used will increase, and its structure will be more varied.

[0003] When the shaft parts to be processed on the assembly line are at a 90° angle to the finished products processed on the workbench, it is generally difficult to complete the exchange of the positions of the two sides of the parts with one rotation, and the motion process involved is more complicated. In response to this situation, most of the existing loading and unloading manipulators complete loading and unloading through the superposition and combination of actuators. Although this mechanism is highly flexible, it requires more actuators, occupies a larger space, is heavier in weight, and has a higher overall cost. Therefore, it is indeed necessary to design an innovative automatic loading and unloading manipulator for the above situation, so that it can overcome the above-mentioned defects in the prior art while realizing the above-mentioned complex movements and completing the specified loading and unloading actions.

[0059] The present embodiment is further configured that the inner curved surfaces of the first arc-shaped clamping portion Ⅰ11124, the second arc-shaped clamping portion Ⅰ11127, the first arc-shaped clamping portion Ⅱ11224 and the second arc-shaped clamping portion Ⅱ11227 are coated with a rubber coating.

[0060] As attached Figure 1 As shown, it includes a support platform 001, a linear drive 21, a linear cylinder 23, a rotary cylinder 25, and a core grabbing mechanism 10.

[0061] At the initial moment, the core grasping mechanism 10 is located in the waiting area directly above the assembly line; its two mechanical grippers are both in an open state.

[0062] When loading and unloading, the opening and closing states of the two mechanical grippers and the movement sequence of the differential member 11212 in the groove portion II1143 of the driving member II11213 are shown in the attached Fig.13 .

[0063] Step 1: The linear cylinder 23 extends to lower the core grasping mechanism 10 and the wrist rotary cylinder 25 to the designated clamping position, that is, the semicircular claws of the fixed clamp 1a11122 and the fixed clamp 1b11123 are in contact with the short shaft parts 3. Then, the stepper motor 122 operates, and the motor shaft rotates forward to drive the bevel gear Ⅰ124 to rotate the gear shaft Ⅰ11112, and the driving member Ⅰ11113 on the gear shaft Ⅰ11112 rotates accordingly, and the driving rod Ⅰ1132 on the convex part Ⅰ1131 moves in the groove Ⅰ1133 of the driven clamp 1a11125 and the driven clamp 1b11126, driving the two driven clamps of the mechanical clamp Ⅰ111 to rotate, so that the mechanical clamp Ⅰ111 is closed; when the driving member Ⅰ11113 on the driving member Ⅰ11113 After the driving rod portion Ⅰ1132 disengages from the groove portion Ⅰ1133 track of the two driven clamps, the driving member Ⅰ11113 continues to rotate a certain angle. At this time, the outer contour of the driving member Ⅰ11113 is tangent to the outer contours of the two driven clamps, completing the self-locking of the mechanical clamp Ⅰ111 when it is closed. Since the inner curved surfaces of the second arc-shaped clamping portions Ⅰ11127 of the driven clamps 1a11125 and 1b11126 are coated with rubber coatings, the short shaft parts 3 on the assembly line are clamped by two elastic forces. At the same time, bevel gear I124 drives bevel gear II125 and gear shaft II11211, and the differential member 11212 on the gear shaft II11211 rotates accordingly. The driving rod portion II1142 on the convex portion II1141 of the differential member 11212 moves from the angle bisector position of the groove portion II1143 of the driving member II11213 to the rightmost end of the groove portion II1143, and the friction block 131 presses against the driving member II11213, and the driving member II11213 does not slide, so that the driven clamps 2a11225 and 2b11226 remain stationary.

[0064] Step 2: The linear cylinder 23 retracts, causing the core grabbing mechanism 10 and the rotary cylinder 25 to rise to the waiting area of ​​the assembly line, and then the linear drive 21 operates, driving the linear cylinder 23, the rotary cylinder 25 and the core grabbing mechanism 10 to move horizontally to just above the short-axis parts 32 of the workbench. Then the linear cylinder 23 extends, causing the core grabbing mechanism 10 and the rotary cylinder 25 to descend to the designated clamping position, that is, the first arc-shaped clamping part II11224 of the fixed clamp 2a11222 and the fixed clamp 2b11223 are in contact with the short-axis parts 32. Subsequently, the stepper motor 122 operates, and the motor shaft rotates forward to drive the bevel gear Ⅰ124 to rotate, and the bevel gear Ⅰ124 drives the bevel gear Ⅱ125 and the gear shaft Ⅱ11211, and the differential member 11212 on the gear shaft Ⅱ11211 rotates accordingly, and its driving rod portion Ⅱ1142 rotates against the rightmost end of the groove portion Ⅱ1143 of the driving member Ⅱ11213, thereby driving the driving member Ⅱ11213 to rotate; the driving rod portion Ⅲ1152 of the driving member Ⅱ11213 moves in the groove portion Ⅲ1153 of the driven clamp 2a11225 and the driven clamp 2b11226, driving the mechanical clamp Ⅱ1 The two driven clamps of 12 rotate to close the mechanical clamp II112; when the driving rod III1152 of the driving member II11213 is separated from the groove III1153 track of the two driven clamps, the driving member II11213 continues to rotate a certain angle, at which time the outer contour of the driving member II11213 is tangent to the outer contours of the two driven clamps, completing the self-locking of the mechanical clamp II112 when it is closed. Since the inner arc surface of the second arc-shaped clamping part II11227 of the driven clamp 2a11225 and the driven clamp 2b11226 is coated with rubber coating, the short shaft parts 32 on the workbench are clamped by two elastic forces. At the same time, the mechanical clamp I111 remains self-locking, and the self-locking angle increases.

[0065] Step 3: The linear cylinder 23 retracts, causing the core grabbing mechanism 10 and the rotary cylinder 25 to rise a short distance to prevent subsequent actions from interfering with the workbench. The rotary cylinder 25 then operates to rotate the core grabbing mechanism 10 90° clockwise along the rotation center. The linear cylinder 23 then extends, causing the core grabbing mechanism 10 and the rotary cylinder 25 to descend to the designated clamping position, that is, the short shaft part 3 contacts the workbench clamping position. Then the motor shaft reverses to drive the bevel gear Ⅰ124 to rotate in conjunction with the gear shaft Ⅰ11112, and the driving member Ⅰ11113 on the gear shaft Ⅰ11112 rotates accordingly; the driving rod portion Ⅰ1132 of the driving member Ⅰ11113 cuts into the groove portion Ⅰ1133 track of the driven clamp 1a11125 and the driven clamp 1b11126 from the outside, and continues to rotate, driving the driven clamp 1a11125 and the driven clamp 1b11126 to rotate, so that the mechanical clamp Ⅰ111 opens to the limit opening angle; at the same time, the bevel gear Ⅱ125 drives the differential member 11212 to idle along the groove portion Ⅱ1143 of the driving member Ⅱ11213 to the leftmost end of the groove portion Ⅱ1143 of the driving member Ⅱ11213. At this time, the driving member Ⅱ11213 is resisted by the friction block 131, keeping its position unchanged, and the driven clamp mechanical clamp Ⅱ112 remains closed and self-locking.

[0066] Step 4: The linear cylinder 23 retracts, causing the core grabbing mechanism 10 and the rotary cylinder 25 to rise, and then the linear drive 21 operates, driving the linear cylinder 23, the rotary cylinder 25 and the core grabbing mechanism 10 to move horizontally to the top of the assembly line. Then the rotary cylinder 25 operates, causing the core grabbing mechanism 10 to rotate 180° counterclockwise along the rotation center. Then the linear cylinder 23 extends, causing the core grabbing mechanism 10 and the rotary cylinder 25 to descend to the designated clamping position, that is, the short shaft parts 32 are in contact with the assembly line clamping position. Then the stepper motor 122 operates, the motor shaft reverses to drive the bevel gear Ⅰ124 to rotate, the bevel gear Ⅰ124 drives the bevel gear Ⅱ125 and the gear shaft Ⅱ11211, and the differential member 11212 on the gear shaft Ⅱ11211 rotates accordingly, and the driving rod portion Ⅱ1142 on the convex portion Ⅱ1141 presses against the leftmost end of the groove portion Ⅱ1143 of the driving member Ⅱ11213 to rotate, thereby driving the driving member Ⅱ11213 to rotate; the driving rod portion Ⅲ1152 of the driving member Ⅱ11213 is in the groove portion Ⅲ1152 of the driven clamp 2a11225 and the driven clamp 2b11226. 53 moves, driving the two driven clamps of mechanical clamp Ⅱ112 to rotate, so that mechanical clamp Ⅱ112 opens; at the same time, bevel gear Ⅰ124 drives gear shaft Ⅰ11112 to rotate in conjunction with driving member Ⅰ11113, so that the driving rod portion Ⅰ1132 on the convex portion Ⅰ1131 of driving member Ⅰ11113 cuts into the concentric circle orbit of the groove portion Ⅰ1133 of the driven clamp 1a11125 and the driven clamp 1b11126, and continues to rotate; at this time, the driven clamp 1a11125 and the driven clamp 1b11126 remain stationary, and the mechanical clamp Ⅰ111 is self-locked at the limit opening angle.

[0067] Step 5: The linear cylinder 23 retracts, causing the core grabbing mechanism 10 and the rotary cylinder 25 to rise to the waiting area. Then the rotary cylinder 25 rotates 90° clockwise, and the stepper motor 122 operates. The motor shaft rotates forward to drive the bevel gear I 124 and the bevel gear II 125 to rotate the two gear shafts to a certain angle and stop. At this time, all mechanisms return to their initial positions.

[0068] The present invention can complete the loading and unloading of the shaft-like short-shaft parts 3 to be added on the assembly line when the angle between the shaft-like short-shaft parts and the finished product on the workbench is 90°. The biggest innovation is that a stepper motor 122 drives two clamps with an angle of 90°, and the mechanical structure enables them to open and close in a specified order without interfering with each other, and can achieve self-locking when the linear driver 21 and the cylinder drive the parts to move. The clamping of the parts adopts double-jaw center clamping, which has higher stability than the single clamp of the pneumatic finger and ensures coaxiality. The size of each component of the present invention is relatively small, and the processing is simple. Compared with the existing loading and unloading manipulator for the shaft-like short-shaft parts 3 to be added and the finished product on the workbench, the whole mechanism is lighter and occupies less space. The actuators used are only a linear driver 21, a linear cylinder 23, a rotary cylinder 25 and a stepper motor 122, which are relatively low in cost, pollution-free, oil-free, and simple to control.
