The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Please refer to fig. 1, which is a schematic structural diagram of a plate mounting apparatus according to an embodiment of the present application; FIG. 2 is a schematic view of the upper plate apparatus of FIG. 1 from another perspective; FIG. 3 is a schematic view of the upper plate apparatus of FIG. 1 in an initial position, torque minimum state; FIG. 4 is a schematic illustration of the upper plate apparatus of FIG. 1 in an intermediate, torque capacity condition; fig. 5 is a schematic view of the upper plate apparatus of fig. 1 in an upper position.
In an embodiment, as shown in fig. 1 and fig. 2, the plate loading device of the appearance inspection machine for a plate 700 to be tested provided by the present application includes a driving part and a gripping part 200 connected to the driving part, where the gripping part 200 is used to absorb the plate 700 to be tested; under the driving of the driving part, the grabbing part 200 transports the plate 700 to be measured from the initial position to the upper plate position; the gripping members 200 comprise at least two rows; the driving component drives the grabbing component 200 to rotate periodically, so that the grabbing component 200 drives the board 700 to be tested to rotate from the initial position to the upper plate position around the predetermined rotation axis 501.
Specifically, the rotation axis 501 is disposed below the plate material 700 to be measured, and the rotation axis 501 coincides with a plane where the plate material 700 to be measured is located at the initial position. It should be noted that, in actual use, due to the offset of the sheet material to be measured, the rotation axis 501 does not necessarily coincide with the plane of the sheet material 700 to be measured in the initial position. The rotation axis 501 coincides with the plane where the board 700 to be measured is located at the initial position, which means that the rotation axis 501 and the plane where the board 700 to be measured is located at the initial position are substantially in the same plane, which is to ensure that different gripping devices can simultaneously contact with the board 700 to be measured, so as to facilitate gripping.
In the prior art, the first and the second grabbing parts are generally arranged in a row or one, and the board 700 to be measured is adsorbed by a single adsorption force point, so that the board 700 to be measured cannot be damaged too fast in the movement process, and the board 700 to be measured is easily damaged if the first and the second grabbing parts are too fast, so that the movement speed of the board 700 to be measured is low, and the fastest speed is generally 800 pieces/hour. Secondly, in the process of loading the plate, because the plate is dropped, separated and insufficiently stressed due to the single acting point and horizontal acting force.
In the present application, the gripping member 200 includes at least two rows; the driving component drives the grabbing component 200 to rotate periodically, so that the grabbing component 200 drives the board 700 to be tested to rotate from the initial position to the upper plate position around a predetermined rotation center 501.
In this structure, as shown in fig. 3, the initial position, the intermediate position, and the upper plate position are explained as follows:
as shown in fig. 3, the plate 700 to be measured is located at the right side, and the upper side is inclined to the right side, and the lower side is inclined to the left side, and the position of the plate 700 to be measured at this time is the initial position.
As shown in fig. 4, during the transportation of the board 700 to be tested, the board 700 to be tested is in a vertical state, and the board 700 to be tested is defined as a middle position.
As shown in fig. 5, when the plate 700 to be measured moves to the right, the plate 700 to be measured is located at the left side, and the plate 700 to be measured is inclined to the left side in the up direction and inclined to the right side in the down direction, and the position of the plate 700 to be measured at this time is the upper plate position. The board 700 to be measured moves on the conveyor and enters the next step.
The motion process of the present application is described as follows:
as shown in fig. 3, the driving part drives the grabbing part 200 to rotate clockwise, and rotates to an initial position, so that the grabbing part 200 adsorbs the board 700 to be detected; next, as shown in fig. 4, the driving part drives the grasping part 200 to rotate counterclockwise, passing through the intermediate position; as shown in fig. 5, the gripping member 200 continues to rotate counterclockwise to reach the upper plate position by the driving of the driving member.
In the present application, the substantially more uniform force is provided by the gripping members 200 having at least two rows. At this moment, because the rotation transportation is adopted, the speed can be increased, and therefore the structural design of the device can improve the upper plate speed of the plate 700 to be tested, and the plate 700 to be tested is stressed uniformly. In addition, because two rows of gripping members 200 at least, therefore adsorb more firmly, avoid producing and fall the board, break away from and the problem that suction is not enough.
Through tests and tests, the plate feeding speed of the plate feeding device with the structure can reach 1900 pieces/hour, and is increased by over 100 percent compared with 800 pieces/hour in the prior art, so that the plate feeding speed is obviously increased.
In some embodiments, further improvements may be made to the above structure. For example, as shown in fig. 1 and 2, the driving part includes a rotation shaft 402, the rotation shaft 402 being separated from the rotation axis 501 and located on one side of the rotation axis 501 at the upper plate position; the rotation shaft 402 drives the absorption component to periodically rotate, so that the absorption component drives the plate to be tested to rotate from the initial position to the upper plate position around the predetermined rotation axis 501.
In this structure, since the rotation shaft 402 is separated from the rotation axis 501, when the rotation shaft 402 of the driving part rotates the gripping part around the rotation axis 501, since the rotation shaft 402 is located on the side of the rotation axis 501 at the upper plate position, it is possible to have a large position space for providing the buffer. It should be noted that, in the present application, since the horizontal translation is replaced by the periodic rotation, there is a problem that a large impact force is generated when the speed is changed while the speed of the upper plate is increased. In the present configuration, since the rotation shaft 402 is separated from the rotation axis 501 and is located on the upper plate position side of the rotation axis 501, a large position space can be provided for installing a buffer device, thereby reducing the problem of a large impact force during speed increase.
In some embodiments, further designs may be made for the above structure. For example, as shown in fig. 1 and fig. 2, the upper plate device further includes a mounting component, and the grabbing component 200 is fixedly mounted on the mounting component and faces the plate 700 to be measured; the driving member is connected to the mounting member to drive the mounting member and the gripping member 200 to rotate periodically.
In the above technical scheme, through the design of this installing component, this installing component plays the effect of middle transition, and the drive unit passes through the motion of drive installing component, and the installing component then drives the motion of grabbing part 200 for drive unit can be better with the grabbing part 200 be connected the drive.
It should be noted that the present application is not limited to the specific structure of the mounting component. Such as a plate, a bar, a frame member or other structure, which can serve to secure the grasping member 200 and move the next piece driven by the driving member, should be within the scope of the present application.
As an example, we can specifically design a structure of the mounting part. For example, as shown in fig. 1 and fig. 2, the mounting component is a mounting plate 300, and a card slot 301 is disposed on the mounting plate 300; the grabbing component 200 is fixedly connected to the clamping groove 301 through an adsorption handle, and a suction cup at the tail end of the grabbing component faces the plate 700 to be detected.
As shown in fig. 1 and 2, in the above structure, the mounting plate 300 includes three support plates, each of which is provided with a slot 301, and the grasping member 200 is fixed in the slot 301. This construction involves, on the one hand, a reduction in weight and, on the other hand, the possibility of ensuring the reliability of the fastening. Therefore, the speed of the upper plate is further improved on the premise of reliable fixation.
In some embodiments, further designs can be made on the technical scheme. For example, as shown in fig. 1 and fig. 2, the driving part includes a driving motor 401, a rotating shaft 402 driven by the driving motor 401, and a connecting rod 403 driven by the rotating shaft 402, and the connecting rod 403 is fixedly connected to the mounting part so as to drive the mounting part to rotate periodically.
In this structure, the driving motor 401 provides power to drive the rotating shaft 402 to rotate, the rotating shaft 402 further drives the connecting rod 403 to swing, the connecting rod 403 further drives the mounting component to swing, and finally the grabbing component 200 swings.
In the prior art described above, the driving member can only move horizontally, so as to drive the grabbing member 200 to move horizontally, and thus the grabbing member 200 applies a force horizontally, which results in a low movement speed of the board 700 to be measured, i.e. 800 pieces/hour in a fastest case. Meanwhile, the problems of falling, separation and insufficient stress are easily caused.
In the above technical solution, the motor outputs the rotation power, and further the rotation shaft 402 and the connecting rod 403 are used to finally swing the mounting component and the grabbing component 200, and the grabbing component 200 has at least two rows, so that the speed of the upper plate can be significantly increased, and the grabbing component 200 can firmly adsorb the plate 700 to be tested, thereby avoiding the problems of plate falling, separation, insufficient stress and the like. Therefore, the structural design of the device can change the horizontal movement adsorption of the grabbing part 200 into periodic rotation adsorption, thereby increasing the adsorption force, improving the speed of the upper plate, and avoiding the problems of plate falling, separation, insufficient stress and the like.
In any of the above embodiments, as described earlier, in the present application, since the horizontal translation is replaced with the periodic rotation, there is also a problem that a large impact force is generated when the speed changes while the upper plate speed is raised. In the present configuration, since the rotation shaft 402 is separated from the rotation axis 501 and is located on the upper plate position side of the rotation axis 501, a large position space can be provided for installing a buffer device, thereby reducing the problem of a large impact force during speed increase.
Thus, in one embodiment provided by the present application, the upper plate device includes a base and a buffer device, and the buffer device is disposed between the base and the driving member so as to buffer the impact force applied to the driving member.
Specifically, as shown in fig. 1 and 2, the structure of the above-described buffer device may be specifically set. For example, the driving part includes a rotating shaft and a connecting rod 403 connected to the rotating shaft, and the rotating shaft drives the grabbing part to rotate through the connecting rod 403; the buffer device comprises a sliding plate 404 fixed with the rotating shaft and rotating along with the rotating shaft, and a sliding block 405 sliding on the sliding plate 404; the connecting rod 403 is rotatably connected with the sliding block 405, the sliding block 405 is driven to slide back and forth on the sliding plate 404 and rotate along with the rotation of the sliding plate 404, and the sliding block 405 drives the connecting rod 403 to periodically rotate, so that the connecting rod 403 is matched with the sliding plate 404 and the sliding block 405 to periodically swing in a speed-up and speed-down manner.
In the above embodiment, as shown in fig. 1 and fig. 2, the driving part further includes a sliding plate 404 fixed to the rotating shaft 402 for rotation therewith, and a slider 405 sliding on the sliding plate 404; the connecting rod 403 is rotatably connected to the sliding block 405, so that as the sliding plate 404 rotates, the sliding block 405 is driven to slide back and forth on the sliding plate 404 and rotate, and the sliding block 405 drives the connecting rod 403 to periodically rotate.
In the above technical solution, the grabbing part 200 needs to swing left and right, and the left and right limitation is needed. In order to realize the function, the technical scheme further designs a transmission structure from the rotating shaft 402 to the mounting part. Specifically, as shown in fig. 1 and fig. 2, the driving part further includes a sliding plate 404 fixed to the rotating shaft 402 and rotating therewith, and a sliding block 405 sliding on the sliding plate 404; the connecting rod 403 is rotatably connected to the sliding block 405, so that as the sliding plate 404 rotates, the sliding block 405 is driven to slide back and forth on the sliding plate 404 and rotate, and the sliding block 405 drives the connecting rod 403 to periodically rotate.
It should be noted that, when the motor 401 rotates clockwise, the first rotating disc 406 drives the second rotating disc 407 to rotate through the belt 408, and since the diameter of the first rotating disc 406 is much smaller than that of the second rotating disc 407, after the motor 401 rotates several circles, the second rotating disc 407 rotates clockwise by a certain angle, and the movement process at this time is from the position in fig. 3, through the position in fig. 4, to the position in fig. 5, so that the adsorption process from the initial position to the upper plate position of the plate to be measured is realized. Then, when the motor 401 rotates counterclockwise, the motion process is reversed, and will not be described again.
In operation, as shown in fig. 3, when the board 700 to be measured moves from the initial position to the middle position, the sliding plate 404 rotates downward under the driving of the driving motor 401 and the rotating shaft 402, and the sliding block 405 moves leftward along the sliding plate 404, so as to drive the grabbing component 200 to rotate counterclockwise. As shown in fig. 4 and 5, when the board 700 to be measured moves from the middle position to the upper plate position, the sliding plate 404 continues to rotate downward under the driving of the driving motor 401 and the rotating shaft 402, the sliding block 405 moves rightward along the sliding plate 404, and further drives the grabbing component 200 to continue to rotate counterclockwise until the upper plate position.
Then, when the gripping member 200 is reset to the initial position, the process is reversed.
Obviously, the grabbing part 200 can swing left and right well by the aid of the structural design, and left and right limiting is needed. In addition, the above structure was subjected to stress analysis as follows:
as shown in fig. 3, the motor transmits power to the suction plate structure through the belt 408 device, the final power is a, which is divided into b and c because a is a diagonal force, and the actual effective force is b, which is divided into b1 and b2 because the force direction is around the rotation center 501, and c is also divided into c1 and c 2. As the whole suction plate structure ascends, b1 sharply decreases, and c1 sharply increases, eventually resulting in b1 and c1 balancing, thereby greatly reducing the large impact force when the whole suction plate structure moves. Therefore, when the high-speed rotation is ensured and the speed of the upper plate is increased, the structural design can obviously reduce the huge impact force when the whole suction plate structure moves.
In some embodiments, the above technical solutions may also be specifically designed. For example, as shown in fig. 1 and fig. 2, the plate loading apparatus further includes a U-shaped base 500, the rotation shaft 402 is rotatably disposed on a supporting arm on one side of the U-shaped base 500, and the rotation center 501 is disposed on a supporting arm on the other side of the U-shaped base 500.
In the above structure, the U-shaped base 500 is designed to provide a support for the rotating shaft 402 and the motor, so as to facilitate the rotation of the rotating shaft 402, and thus to drive the grabbing part 200 to swing. On the other hand, the swing center 501 of the plate 700 to be measured is provided, so that the plate 700 to be measured is positioned more accurately in the moving process.
In any of the above embodiments, further improvements may be made to further reduce the impact force. For example, as shown in fig. 1 and fig. 2, the buffering device further includes a buffering rod assembly, where the buffering rod assembly includes a plurality of buffering rods hinged to each other; one end of the bumper bar assembly is hinged to the slider 405, and the other end of the bumper bar assembly is hinged to the rotation axis 501. In addition, the buffering device further comprises a buffering spring 604, wherein one end of the buffering spring 604 is hinged to the bottom supporting arm of the U-shaped base 500, and the other end of the buffering spring 604 is integrally hinged to the buffering rod.
In the above technical solution, the impact force generated by the grabbing component 200 during the movement process can be significantly reduced through the buffer action of the buffer rod and the buffer spring 604.
In some embodiments, the buffer rod may be specifically designed. For example, as shown in fig. 1 and fig. 2, the buffering rod assembly includes a straight rod 601, a V-shaped rod 603, and a hinge base 602 hinged between the straight rod 601 and the V-shaped rod 603, the other end of the straight rod 601 is hinged to the sliding block 405, and the other end of the V-shaped rod 603 is hinged to the rotation center 501; the buffer spring 604 is hinged to the hinge base 602.
In the above structure, the straight rod 601 and the V-shaped rod 603 are hinged by the hinge base 602, the straight rod 601 is hinged to the slider 405, the V-shaped rod 603 is hinged to the rotation center 501, and the buffer spring 604 is hinged to the hinge base 602. In operation, as the grabbing part 200 swings, the buffer rod is also in rotation linkage, so that the buffer impact force is realized.
In some embodiments, as shown in fig. 1 and 2, the connecting rod 403 is an L-shaped rod. Through the action of the L-shaped rod piece, the installation component and the grabbing component 200 can swing better.
Further, as shown in fig. 1 and 2, the driving motor 401 includes an output shaft to which a first rotary disk 406 is fixed, a second rotary disk 407 is fixed to the rotary shaft 402, and a diameter of the second rotary disk 407 is larger than a diameter of the first rotary disk 406; the first turntable 406 and the second turntable 407 are driven by a belt 408.
In the above structure, since the second dial 407 has a larger diameter than the first dial 406, the output torque is increased, thereby providing a greater rotational force.
It should be noted that any shape of base, provided that it provides support for the shaft 402 on one side and the rotation axis 501 on the other side, is within the scope of the present application. As an example, in one embodiment, as shown in fig. 4 and 5, the base is a U-shaped base 500, and the U-shaped base 500 includes a first supporting arm located at one side of the upper plate position of the plate 700 to be measured, and a second supporting arm located at one side of the initial position of the plate 700 to be measured; the rotating shaft is rotatably arranged on the first supporting arm, and the rotating axis is positioned on the second supporting arm. As shown in fig. 4 and 5, the left support arm of the U-shaped base 500 is a first support arm, and the right support arm is a second support arm. The structural design can very conveniently realize the support of the rotating shaft, and in addition, enough space can be provided, so that the arrangement of the buffer device is convenient.
In addition, the application also provides an appearance inspection machine for the plate to be detected, which comprises an inspection machine body; the appearance inspection machine for the plate to be detected further comprises any one of the plate loading devices of the appearance inspection machine for the plate to be detected, and the plate loading devices are arranged on the inspection machine body.
Finally, through tests and tests, the plate loading speed of the plate loading device with the structure can reach 1900 pieces/hour, and is increased by over 100 percent compared with 800 pieces/hour in the prior art, so that the plate loading speed is obviously increased.
