Description

Technical Field

[0001] The utility model relates to the technical field of plate conveying and positioning, in particular to a conveying device with a plate belt rotation function. Background Art

[0002] Currently, common conveying mechanisms generally only have the functions of conveying and positioning panels. In the production process of panels, to change the conveying direction of the panels, suction cups are usually used to absorb the circuit boards and rotate them, or an overall rotating mechanism of the conveying section is designed.

[0003] Currently, the market generally uses suction cups to absorb circuit boards for rotation or designs an overall rotating mechanism for the conveying section to change the conveying direction during the circuit board production process. However, when using a suction cup rotating mechanism, the circuit board may fall off from time to time during the rotation of the suction cup due to excessive rotation speed, increased centrifugal force, and insufficient suction of the suction cup. This will cause damage to the circuit board, affect the quality of board production, and reduce the yield rate of the circuit board. Some machines are designed with a mechanism for the overall rotation of the conveying section. This method has a large rotation radius during rotation, resulting in a large footprint of the machine and low utilization of the internal space of the machine, which cannot be used in some occasions.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 6 As shown, a conveying device with a lifting plate and a rotating function of the utility model comprises a lifting plate 1, a moving alignment mechanism 2, a rotating mechanism 3, a lifting mechanism 4, a conveying frame 5, and a mechanism mounting plate 7. The conveying frame 5 is provided with a plurality of conveying wheels 51, and the lifting plate 1 is provided with a plurality of avoidance holes 11 for avoiding the conveying wheels 51. The lifting plate 1 is movably arranged on the conveying frame 5 and the avoidance holes 11 are aligned with the conveying wheels 51. The mechanism mounting plate 7 is movably connected to the conveying frame 5. The two ends of the moving alignment mechanism 2 are respectively connected to the conveying frame 5 and the mechanism mounting plate 7. The lifting mechanism 4 is connected to the mechanism mounting plate 7. The rotating mechanism 3 is connected to the lifting mechanism 4. The lifting plate 1 is connected to the rotating mechanism 3. The lifting mechanism 4 drives the rotating mechanism 3 to rise and fall to drive the lifting plate 1 to rise and fall, and the rotating mechanism 3 drives the lifting plate 1 to rotate.

[0028] The conveying device is mainly composed of a lifting plate 1, a moving alignment mechanism 2, a rotating mechanism 3 and a lifting mechanism 4. Through the cooperation of these mechanisms, the conveying direction of the circuit board can be changed during the conveying process. The lifting plate 1 is used to lift the circuit board and drive the circuit board to rotate. The avoidance hole 11 of the lifting plate 1 allows the conveying wheel 51 to pass through, so that when the lifting plate 1 is lowered, the conveying wheel 51 can contact the circuit board and complete the transmission of the circuit board. The rotating mechanism 3 and the lifting mechanism 4 are connected to the mechanism mounting plate 7. Under the action of the moving alignment mechanism 2, the fine-tuning displacement between the mechanism mounting plate 7 and the conveying frame 5 can be achieved, thereby achieving fine-tuning of the lifting plate 1 in the horizontal direction, so that the avoidance hole 11 of the lifting plate 1 can be aligned with the conveying wheel 51.

[0029] The mobile alignment mechanism 2 includes a mobile motor 21 and a screw rod 22. The mobile motor 21 is fixedly connected to the conveying frame 5. The screw rod 22 is connected to the output end of the mobile motor 21. The screw rod 22 is connected to the mechanism mounting plate 7 by threads. A slide rail 55 is provided at the bottom of the conveying frame 5. The mechanism mounting plate 7 is provided with a slider 71. The slide rail 55 is connected with the slider 71. The mobile motor 21 drives the screw rod 22 to rotate, and through the threaded connection with the mechanism mounting plate 7, the rotational motion is converted into the horizontal linear motion of the mechanism mounting plate 7. The slide rail 55 and the slider 71 cooperate to assist the mechanism mounting plate 7 to slide relative to the conveying frame 5.

[0030] The moving alignment mechanism 2 is a device for moving the lifting plate 1, and the position of the lifting plate 1 is controlled by the screw rod 22. When the lifting plate 1 has completed its rotation, the lifting plate 1 moving alignment mechanism 2 operates, and the moving motor 21 drives the screw rod 22 to rotate, thereby driving the lifting plate 1 to move in the horizontal direction, so that the avoidance hole 11 on the lifting plate 1 is aligned with the transmission wheel 51 of the transmission mechanism, solving the problem that the avoidance hole 11 of the lifting plate 1 does not correspond to the transmission wheel 51 after the rotation of the lifting plate 1.

[0031] The lifting mechanism 4 includes a lifting cylinder 41, a lifting plate 42, and a cylinder mounting plate 43. The cylinder mounting plate 43 is fixedly connected, the lifting cylinder 41 is connected to the cylinder mounting plate 43, the output end of the lifting cylinder 41 is connected to the lifting plate 42, and the rotating mechanism 3 is connected to the lifting plate 42. The lifting mechanism 4 also includes a lifting guide rod 44, the two ends of which are respectively connected to the mechanism mounting plate 7 and the cylinder mounting plate 43. The lifting plate 42 is provided with a guide ring 45, and the guide ring 45 is movably connected to the lifting guide rod 44. The cooperation between the guide ring 45 and the lifting guide rod 44 guides the moving direction of the lifting plate 42.

[0032] The lifting mechanism 4 is a device for lifting the lifting plate 1. The lifting and lowering of the lifting plate 1 is controlled by the lifting cylinder 41, that is, by driving the rotating mechanism 3 to rise, the lifting plate 1 is lifted up by the other end of the rotating shaft 32. When the circuit board reaches the set position, the lifting cylinder 41 extends, and the lifting plate 1 rises to lift the circuit board, and is higher than the surface of the conveying wheel 51 of the conveying frame 5, so as to avoid friction between the conveying wheel 51 and the circuit board components during the rotation of the circuit board components, thereby reducing unnecessary damage to the surface of the circuit board components.

[0033] The rotating mechanism 3 includes a rotating motor 31 and a rotating shaft 32. The rotating motor 31 is connected to the lifting plate 42. One end of the rotating shaft 32 is connected to the output end of the rotating motor 31. The conveying frame 5 is provided with an avoidance groove 56. The other end of the rotating shaft 32 passes through the avoidance groove 56 and is connected to the lifting plate 1. When rotating, the rotating motor 31 drives the rotating shaft 32 to drive the lifting plate 1 to rotate. The rotating motor 31 is a servo motor. The avoidance groove 56 of the conveying frame 5 provides sufficient space for the rotating shaft 32 to perform vertical lifting and horizontal displacement fine adjustment.

[0034] The rotating mechanism 3 is a device for rotating the lifting plate 1, and the rotation of the lifting plate 1 is controlled by a servo motor. The lifting plate 1 is connected to the rotating mechanism 3. When the lifting plate 1 lifts the circuit board away from the roller, the rotating mechanism 3 operates, and the servo motor drives the rotating shaft 32 to drive the lifting plate 1 and the circuit board to rotate, thereby changing the conveying direction of the circuit board.

[0035] The conveying device with the function of supporting the board belt rotation also includes a position sensor 6, which is connected to the conveying frame 5 to monitor the position of the product to be conveyed. Position sensors 6 can be set at the feeding end, the discharging end, and the middle end of the conveying frame 5 to sense whether the circuit board has reached the specified position.

[0036] The conveying device for supporting the plate belt rotation function also includes a transmission motor 52 and a transmission shaft 53. The transmission motor 52 and the transmission shaft 53 are connected to the transmission frame 5. The transmission motor 52 is connected to the transmission shaft 53, and the transmission shaft 53 is connected to multiple transmission wheels 51. The transmission wheel 51 can be a magnetic roller, and the transmission motor 52 drives the multiple magnetic rollers through the transmission shaft 53 for synchronous transmission.

[0037] The conveying frame 5 is provided with a supporting protrusion 54, and when the lifting plate 1 is placed on the conveying frame 5, the supporting protrusion 54 butts against the lifting plate 1. When the rotating mechanism 3 lowers the lifting plate 1 to a certain height, the lifting plate 1 is supported by the supporting protrusion 54, which plays an auxiliary supporting role, and the lifting plate 1 is placed on the conveying frame 5. At this time, the conveying wheel 51 passes through the avoidance hole 11 and protrudes from the lifting plate 1.

[0038] The working process of the conveyor device with the function of supporting the plate belt rotation:

[0039] 1. The circuit board is transferred from the outlet of the transfer section of the previous process section to the transfer device, and the transmission motor 52 drives the transmission shaft 53 to rotate, thereby driving the magnetic roller to rotate and drive the circuit board to move to a predetermined position.

[0040] 2. When the position sensor 6 senses that the circuit board has reached the predetermined position, the lifting cylinder 41 in the lifting mechanism 4 extends, driving the rotating mechanism 3 to rise, so that the lifting plate 1 lifts the circuit board.

[0041] 3. The rotating mechanism 3 starts to operate, rotating the lifting plate 1 and the circuit board thereon by 90 degrees.

[0042] 4. After the rotation is completed, the mobile alignment mechanism 2 starts to operate, driving the mechanism mounting plate 7 to perform horizontal fine-tuning movement to align the roller avoidance hole 11 on the lifting plate 1 with the magnetic roller on the conveying frame 5 by adjusting the horizontal position of the lifting plate 1.

[0043] 5. When the roller avoidance hole 11 on the lifting plate 1 is aligned with the magnetic roller, the lifting plate 1 is lowered to place the circuit board on the magnetic roller of the conveying device. The conveying device is started to convey the circuit board to the entrance of the conveying section of the next process section.

[0044] The above is the working process of the conveying mechanism using the rotating mechanism 3 to achieve the function of changing the orientation of the circuit board.

[0045] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
