Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide processing, in particular to a conveying device for a silicon carbide roller. Background Art

[0002] Silicon carbide ceramics are an industrial material with the characteristics of high mechanical strength, high hardness, high temperature resistance, chemical corrosion resistance, excellent oxidation resistance and thermal shock resistance, good thermal conductivity, and low expansion coefficient. In particular, its oxidation resistance is the best among all non-metallic ceramics. It is often used in the production of complex special-shaped parts in electronic packaging, aerospace, military, and automotive industries.

[0003] In the field of mechanical processing, the traditional method of conveying the bars to be processed to the processing area is manual feeding, which is too inefficient. With the advancement of technology, the feeding of bars is gradually completed by conveying devices, and mechanical arms are set between the conveying devices and the processing area to complete the grabbing and delivery of the bars. The setting of the conveying device not only greatly improves the conveying efficiency, but also better cooperates with the mechanical arm to improve the grabbing efficiency of the mechanical arm. Horizontal conveyors are usually used at present.

[0004] The prior art discloses a patent CN102897478B, a rod conveying device, including a horizontal conveyor, the horizontal conveyor including at least one transmission group consisting of a driving assembly and a belt traction assembly, the belt traction assembly is provided with at least one row of rod seats along the conveying direction, the rod seats include a support plate perpendicular to the annular plane of the belt traction assembly, and the outer end of the support plate is provided with a concave support portion recessed in the direction of the belt traction assembly. The rod conveying device proposed in the disclosed technology sets a plurality of rod seats for carrying rods, and the rod seats are provided with a concave support portion, which not only stabilizes the position of the rods along the conveying direction, but also leaves a certain space under the rods for easy grasping by the robot arm, and at the same time improves the grasping accuracy by stabilizing the position of the rods.

[0005] However, as the device was put into production, the shortcomings of the technology were gradually exposed, mainly in the following aspects: First, during the conveying process of the bars, multiple bars need to be conveyed simultaneously according to processing needs. This makes it impossible for the device to ensure the synchronization of the conveying and feeding of multiple bars.

[0006] To this end, there is a public technology on the market that proposes a silicon carbide roller conveying processing tooling, which involves the technical field of conveying devices, including a movably arranged support plate, and a plurality of conveying guide plates are arranged in parallel along the longitudinal direction on the upper surface of the support plate, and a conveying channel is formed through the area between adjacent conveying guide plates. The spacing between adjacent conveying guide plates is adjusted by adjusting parts, and conveying plates are slidably installed in each conveying channel along its extension direction, and a plurality of conveying plates are synchronously driven to feed and move through linkage parts. The support plate is also provided with a rod auxiliary support mechanism at the end of the conveying. The improved technology claims that it solves the problem that the device in the traditional technology cannot carry out directionally guided conveying of rods of different diameters in groups during the process of conveying rods, and has a narrow scope of use; However, the disadvantages of the above-mentioned improved technology are also obvious. It drives the silicon carbide roller to move through the linkage parts, namely the feed plate and the screw. When the feed plate moves to the end, the screw needs to rotate in the opposite direction to drive the feed plate to reset to the initial position before continuing the next conveying. Continuous feeding cannot be formed, and each reset action takes a long time, which seriously affects the production and processing efficiency. It is necessary to make further improvements.

After the motor 9 is started, the driving shaft 10 is driven to rotate by the two groups of first synchronous wheels 12 and one group of first synchronous belts 13. When the driving shaft 10 rotates, the three groups of driven shafts 11 are driven to rotate synchronously in the same direction through multiple groups of second synchronous wheels 14 and second synchronous belts 15. The direction and speed of the driving shaft 10 and the three groups of driven shafts 11 are consistent. When the silicon carbide roller rod is placed on the conveying wheel 16, the silicon carbide roller rod can be conveyed in a specified direction by rotation; In order to achieve the purpose of simultaneously conveying multiple groups of silicon carbide rollers, multiple groups of conveying wheels 16 are fixedly connected to the outer wall of the driving shaft 10 and the outer walls of the three groups of driven shafts 11. The outer wall of the conveying wheel 16 is provided with a conveying groove 1601. The conveying wheels 16 on the outer wall of the driving shaft 10 and the outer wall of the driven shaft 11 are evenly spaced and distributed on the left and right sides. Multiple groups of conveying wheels 16 are provided on the outer wall of the driving shaft 10 and the outer walls of the three groups of driven shafts 11, so as to meet the purpose of simultaneously conveying multiple groups of silicon carbide rollers. In order to keep the front ends of multiple groups of silicon carbide rollers aligned when feeding at the same time, an alignment structure is provided inside the bottom box 2 and between a group on the rear side and a group in the middle of the conveying assembly. The alignment structure includes a second cylinder 17, a limit plate 18 and two groups of positioning plates 21. The two groups of positioning plates 21 are fixedly connected to the left and right inner walls of the bottom box 2 in a left-right relative manner. The second cylinder 17 is rotatably connected to the inner lower wall of the bottom box 2 and the connection point between the second cylinder 17 and the bottom box 2 is located in front of the two groups of positioning plates 21 in a top view. The end of the second cylinder 17 away from the inner lower wall of the bottom box 2 is fixedly connected to the first connector 23. The end of the first connector 23 away from the second cylinder 17 is rotatable. A second rotating seat 22 is connected, and the limiting plate 18 is fixedly connected to one end of the second rotating seat 22 away from the first connecting head 23. The front wall of the limiting plate 18 and the left and right sides are fixedly connected with the first rotating seat 19. The two groups of first rotating seats 19 are close to the lower wall of the limiting plate 18. The two groups of first rotating seats 19 are rotatably connected to the inner left wall and the inner right wall of the bottom box 2 through a group of rotating pins 20 respectively. The limiting plate 18 is extended and retracted by the second cylinder 17 to drive it to rotate along the rotating pin 20. When the rear wall of the limiting plate 18 is pressed against the positioning plate 21, the rear wall of the limiting plate 18 is perpendicular to the horizontal plane. The upper wall of the bottom box 2 and the position close to the rear wall are distributed on the left and right sides and are fixedly connected in sequence with multiple groups of positioning seats 8. A positioning groove 801 is provided on the upper wall of the positioning seat 8. The cross section of the positioning groove 801 is V-shaped when viewed from the front. The multiple groups of positioning seats 8 are respectively opposite to the multiple groups of conveying wheels 16 on the driving shaft 10 in front and back. When feeding, the silicon carbide roller rods are placed through the positioning groove 801 on the positioning seat 8 and the conveying groove 1601 on the group of conveying wheels 16 closest to the positioning seat 8. After the silicon carbide roller rods are placed in the multiple positioning grooves 801, the motor 9 is started to drive the silicon carbide roller rods to move forward, and the second cylinder 17 extends the shaft to drive the limit plate 18 to press against the positioning plate 21. When the front ends of the multiple groups of silicon carbide roller rods are in contact with the rear wall of the limit plate 18, the front end alignment of the silicon carbide roller rods is completed. , because the pressure wheel 28 is not pressed on the silicon carbide roller rod at this time, the silicon carbide roller rod and the conveying wheel 16 can be in a sliding state, and the first group of silicon carbide roller rods that contact the limit plate 18 are limited by the limit plate 18 and will not continue to move forward. The conveying wheel 16 continues to rotate until the front ends of all silicon carbide roller rods are in contact with the limit plate 18. At this time, the motor 9 stops rotating. After completing the front end alignment work, the first cylinder 7 close to the inlet drives the slide 24 to descend until the pressure wheel 28 presses the upper wall of the silicon carbide roller rod. At this time, the second cylinder 17 extends the shaft and retracts, driving the limit plate 18 to flip forward to make way, and the motor 9 is started again, driving multiple groups of silicon carbide roller rods with aligned front ends to be conveyed forward synchronously; In order to prevent the silicon carbide roller from moving or slipping when the conveying wheel 16 is feeding, the pressing assembly includes a slide 24 and multiple groups of pressing wheels 28. The slide 24 is slidably connected to the upper wall on the inner side of the upper cover 4 through a guide structure. The multiple groups of pressing wheels 28 are arranged in a rectangular array on the lower wall of the slide 24 in sequence. The multiple groups of pressing wheels 28 are respectively opposite to the multiple groups of conveying wheels 16 in the upper and lower directions. A plurality of hangers 25 distributed in a rectangular array are fixedly connected to the lower wall of the slide 24. The lower wall of the hanger 25 is slidably connected to a slide rod 26 in a through-shaped manner. One end of the slide rod 26 extending into the interior of the hanger 25 is fixedly connected to a limiting block 30. The pressing wheel 28 is rotatably connected to the end of the slide rod 26 away from the limiting block 30 through a second connector 27. The slide rod 26 is square in top view. The outer wall of the slide bar 26 and the spring 29 between the second connecting head 27 and the hanger 25 are sleeved. When the silicon carbide roller is transported by the conveying wheel 16, the first cylinder 7 drives the slide 24 to descend, and then drives the pressing wheel 28 to descend until the pressing wheel 28 is squeezed on the upper wall of the silicon carbide roller. Since the pressing wheel 28 and the second connecting head 27 are in a rotational connection relationship, the conveying of the conveying wheel 16 will not be affected. The pressing wheel 28 is squeezed by the spring 29, and the pressing wheel 28 is driven to press on the upper wall of the silicon carbide roller to form a pressing force. When the motor 9 stops, the silicon carbide roller will not slide in the forward direction due to inertia, and the silicon carbide roller will not slip when the motor 9 is started again, thereby improving the accuracy of feeding. In order to maintain the stability of the slide 24 when it is lifted or lowered, the guide structure includes four groups of guide rods 6, which are all fixedly connected to the upper wall of the slide 24 and close to the four corners of the upper wall of the slide 24 respectively. The ends of the four groups of guide rods 6 away from the slide 24 all penetrate the upper wall of the upper cover 4 and are slidably connected to the upper cover 4. When the slide 24 rises and falls, the upper wall of the slide 24 is always parallel to the inner upper wall of the upper cover 4 through the sliding connection between the four groups of guide rods 6 and the upper wall of the upper cover 4, thereby improving stability. In order to realize the lifting and lowering of the slide 24, a lifting drive structure for driving the slide 24 to lift and lower is provided on the upper wall of the upper cover 4, and the lifting drive structure is set as the first cylinder 7, and the first cylinder 7 is fixedly connected to the upper wall of the upper cover 4. The extended shaft of the first cylinder 7 passes through the upper wall of the upper cover 4 and extends into the interior of the upper cover 4. One end of the first cylinder 7 extending into the interior of the upper cover 4 is fixedly connected to the upper wall of the slide 24. Through the fixed connection relationship between the slide 24 and the extended shaft of the first cylinder 7, the extended shaft of the first cylinder 7 is extended and retracted, which can drive the slide 24 to rise and fall.

[0024] Working principle: three groups of pressing components are respectively arranged corresponding to three groups of conveying components. There are three groups of pressing components and conveying components. The pressing components and conveying components opposite to each other work together. When feeding, the silicon carbide roller rods are placed through the positioning groove 801 on the positioning seat 8 and the conveying groove 1601 on a group of conveying wheels 16 closest to the positioning seat 8. After the silicon carbide roller rods are placed in multiple positioning grooves 801, the motor 9 is started to drive the silicon carbide roller rods to move forward, and the second cylinder 17 extends the shaft to drive the limit plate 18 to press against the positioning plate 21. When the front ends of the multiple groups of silicon carbide roller rods are in contact with the rear wall of the limit plate 18, the front end alignment of the silicon carbide roller rods is completed. At this time, the pressing wheel 28 is not pressed on On the silicon carbide roller rod, the silicon carbide roller rod and the conveying wheel 16 can be in a sliding state. The first group of silicon carbide roller rods that contact the limit plate 18 are limited by the limit plate 18 and will not continue to move forward. The conveying wheel 16 continues to rotate until the front ends of all silicon carbide roller rods are in contact with the limit plate 18. At this time, the motor 9 stops rotating. After completing the front end alignment work, the first cylinder 7 close to the inlet drives the slide 24 to descend until the pressure wheel 28 presses the upper wall of the silicon carbide roller rod. At this time, the second cylinder 17 extends the shaft and retracts, driving the limit plate 18 to flip forward to make way, and the motor 9 is started again, driving multiple groups of silicon carbide roller rods with aligned front ends to be conveyed forward synchronously. Repeating the above actions for subsequent feeding can realize continuous feeding, and the driving shaft When the driving shaft 10 rotates, the three groups of driven shafts 11 are driven to rotate synchronously in the same direction through multiple groups of second synchronous wheels 14 and second synchronous belts 15. The driving shaft 10 and the three groups of driven shafts 11 have the same direction and rotation speed. When the silicon carbide roller rod is placed on the conveying wheel 16, the silicon carbide roller rod can be conveyed in a specified direction by rotation. Multiple groups of conveying wheels 16 are arranged on the outer wall of the driving shaft 10 and the outer walls of the three groups of driven shafts 11, so as to meet the purpose of conveying multiple groups of silicon carbide roller rods at the same time. When the slide 24 rises and falls, the upper wall of the slide 24 is kept parallel to the inner upper wall of the upper cover 4 through the sliding connection of the four groups of guide rods 6 and the upper wall of the upper cover 4, so as to improve the stability. The slide 24 is fixedly connected with the extended shaft of the first cylinder 7. The first cylinder 7 extends and retracts the shaft, which can drive the slide 24 to rise and fall. When the silicon carbide roller is transported by the conveying wheel 16, the first cylinder 7 drives the slide 24 to descend, and then drives the pressure wheel 28 to descend until the pressure wheel 28 is squeezed on the upper wall of the silicon carbide roller. Since the pressure wheel 28 and the second connecting head 27 are in a rotational connection relationship, the conveying of the conveying wheel 16 will not be affected. The pressure wheel 28 is squeezed by the spring 29, and the pressure wheel 28 is driven to press on the upper wall of the silicon carbide roller to form a pressing force. When the motor 9 stops, the silicon carbide roller will not slide in the forward direction due to inertia, and the silicon carbide roller will not slip when the motor 9 is started again, thereby improving the accuracy of feeding.
