Description

Technical Field

[0001] The utility model relates to the technical field of buffer assembly equipment, in particular to a buffer base conveying and feeding mechanism. Background Art

[0002] The main uses of the buffer are to buffer load impacts in machine equipment, avoid collision damage, eliminate noise, increase the cycle speed, improve product quality, etc.; among them, the buffer is composed of a buffer base, pulleys, sliders, oil cylinders, and springs. In the assembly process of the buffer, after the pulleys, sliders, oil cylinders, and springs are sequentially installed on the buffer base, the assembly of the buffer can be completed. There is a specific buffer assembly equipment as follows:

[0003] Chinese patent document with the publication number of CN109968019A discloses an automatic buffer assembly equipment, specifically including: a frame, a controller arranged on the frame, an indexing plate connected to the controller, a base automatic conveying mechanism, a base feeding mechanism, a base oiling mechanism, a rotating block and slider installation mechanism, an oil cylinder installation mechanism, a rotating mechanism, a first spring installation mechanism, a second spring installation mechanism, and a blanking mechanism arranged around the indexing plate and connected to the controller; it can automatically assemble the rotating block, slider, oil cylinder, and spring onto the base in sequence, and blank the finished product after completion, which not only has high production efficiency but also can solve the product quality problems caused by missing assembly.

[0004] As can be seen from the above, in the existing buffer assembly equipment, although a variety of automatic assembly processes have been realized, there are still some deficiencies in the base feeding link. For example, the base feeding mechanism in the existing automatic buffer assembly equipment only uses the cooperation of a conveyor belt and a robotic arm to grab the base from the conveyor belt and directly place it on the assembly position; however, the clamping cylinder on the robotic arm clamps by contacting the width sides of the base with its two execution ends, but this clamping method is not stable, and the base may break away from the clamping cylinder during the feeding process, affecting the subsequent buffer assembly efficiency. Therefore, a buffer base conveying and feeding mechanism is provided to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a buffer base conveying and feeding mechanism for the deficiencies of the existing technology, so as to solve the technical problem that the base of the base feeding mechanism of the existing buffer assembly equipment may break away from the clamping cylinder during the feeding process.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A buffer base conveying and loading mechanism includes a machine platform and a turntable horizontally rotatably arranged on the machine platform. The turntable rotates intermittently, and a number of assembly position jigs arranged in an array around its rotation center point are installed on the turntable. A conveying component for continuously conveying the buffer base is installed on the machine platform, and a lifting and misalignment component connected to the end of the conveying component and used to drive the buffer base to rise by a specified height one by one, and a handling component for transporting the buffer base placed at the specified height to the assembly position jig at the end of the handling track are also installed.

[0008] Furthermore, a number of fixing blocks are arranged on the machine platform below the turntable and in an array around the rotation center point of the turntable. A support roller in contact with the bottom of the turntable is rotatably arranged on each fixing block, and the support roller is placed at the radial eccentricity of the turntable to support it.

[0009] Furthermore, the conveying component includes a first support frame and a belt conveying module installed on the first support frame, and also includes a belt driving module for driving the belt conveying module to operate.

[0010] Furthermore, the lifting and misalignment component includes a support seat and a first cylinder installed on the support seat with its telescopic rod facing upward. The end of the telescopic rod of the first cylinder is installed with a lifting seat placed at the end of the belt conveying module and used to drive the buffer base to rise. The lifting seat has a feeding position where only one buffer base can be placed.

[0011] Furthermore, a stop block for blocking the buffer base conveyed over to the feeding position is arranged on the lifting seat, and a sensor for sensing whether there is a buffer base on the lifting seat is arranged on the stop block.

[0012] Furthermore, the lifting seat is also installed with a second cylinder with its telescopic rod facing the feeding position and the moving direction of the telescopic rod being consistent with the length direction of the buffer base placed at the feeding position. There are two stop blocks on the lifting seat, and they are respectively close to both ends of the feeding position. The second cylinder is close to one of the stop blocks, and the other stop block is in a lying L shape. One end of the buffer base placed at the feeding position is semi-surrounded by the L-shaped stop block, and a pushing block for pushing the buffer base against the L-shaped stop block to straighten it is installed at the end of the telescopic rod of the second cylinder.

[0013] Furthermore, the handling component includes a second support frame and a slider sliding horizontally on the second support frame, and a material grabbing component that can move up and down is installed on the slider.

[0014] Furthermore, a third cylinder with its telescopic rod facing downward is installed on the slider, and a lifting plate is arranged at the end of the telescopic rod of the third cylinder. The material grabbing component is installed on the lifting plate.

[0015] Furthermore, the material grabbing component includes a jaw cylinder installed on the lifting plate with its execution end arranged downward, and clamping blocks for clamping the length side edges of the buffer base are provided on both execution ends of the jaw cylinder.

[0016] Furthermore, convex portions extending towards each other are provided at the bottom ends of the two clamping blocks, and a relief groove for the convex portions to be embedded is provided on the top surface of the lifting seat.

[0017] The beneficial effects of the present utility model are as follows: During feeding, the driving turntable rotates intermittently. After driving one of the assembly position jigs to the end of the handling trajectory of the handling component and then stopping rotating, during the rotation of the turntable, the conveying component operates to continuously convey a plurality of buffer bases. The first buffer base is conveyed to the lifting and misalignment component, and then the lifting and misalignment component is operated to drive the buffer base to rise by a specified height, so that the first buffer base is misaligned with the next buffer base. Finally, the handling component is operated to handle the misaligned buffer base to the assembly position jig placed at the end of the handling trajectory. Then, the turntable is driven to rotate again to drive the next assembly position jig without a buffer base placed thereon to the end of the handling trajectory; moreover, during the handling process of the handling component, the lifting and misalignment component resets to receive the next buffer base and drives the buffer base to rise and be misaligned. With the cooperation of the conveying component and the handling component, automatic feeding processing can be continuously carried out, greatly improving the feeding efficiency.

[0018] Moreover, by setting the lifting and misalignment component to drive a buffer base to rise by a specified height, the purpose is to provide a position for the handling component to clamp the buffer base, facilitating the handling component to clamp the buffer base from the length side edge of the buffer base, making the handling process more stable and the buffer base not separating from the handling component.

[0025] The following describes in detail a buffer base conveying and loading mechanism of the present utility model with reference to the accompanying drawings.

[0026] As Figure 1 shown, an embodiment of a buffer base conveying and loading mechanism of the present utility model includes a machine platform 102 and a turntable 103 horizontally rotatably arranged on the machine platform 102. The turntable 103 rotates intermittently, and a plurality of assembly position jigs 105 arranged in an array around its rotation center point are installed on the turntable 103. The assembly position jig 105 is a working station for assembling the buffer. The turntable 103 drives the assembly position jig 105 to rotate intermittently and cooperates with other loading mechanisms for loading buffer components, and sequentially places the components of the buffer on the same assembly position jig 105 according to the assembly process for assembly processing. In order to enable the turntable 103 to rotate intermittently automatically on the machine platform 102, an intermittent drive component 104 is installed on the machine platform 102, and the turntable 103 is installed on the intermittent drive component 104. By operating the intermittent drive component 104, the turntable 103 is driven to rotate intermittently. The intermittent drive component 104 is a prior art. In practice, a servo motor assembly can be used, or a structure such as a missing gear driving a full gear to rotate intermittently that can drive the turntable 103 to rotate intermittently can be used, and details are not described herein.

[0027] Additionally, a plurality of fixed blocks 106 are provided on the machine platform 102 below the turntable 103 and arranged in an array around the rotation center point of the turntable 103. A support roller 107 in contact with the bottom of the turntable 103 is rotatably provided on each fixed block 106. The support roller 107 is placed at the radial eccentricity of the turntable 103 to support it, so that the turntable 103 is stable when rotating, and when the components of the buffer are sequentially placed on the same assembly position jig 105 according to the assembly process for assembly, the turntable 103 will not shift, improving the assembly accuracy.

[0028] During the installation of the buffer, in order to automatically and intermittently feed the buffer base 1001, a conveying component 21 for continuously conveying the buffer base 1001 is installed on the machine table 102, and a lifting and offsetting component 22 connected to the end of the conveying component 21 and used to drive the buffer base 1001 to rise by a specified height one by one, and a handling component 23 for moving the buffer base 1001 placed at the specified height to the assembly fixture 105 at the end of the handling track are also installed.

[0029] The intermittent driving component 104 drives the turntable 103 to rotate. After driving one of the assembly fixtures 105 to the end of the handling track of the handling component 23, it stops rotating. During the rotation of the turntable 103, the conveying component 21 is operated to continuously convey a plurality of buffer bases 1001, and the first buffer base 1001 is conveyed to the lifting and offsetting component 22. Then, the lifting and offsetting component 22 is operated to drive the buffer base 1001 to rise by a specified height, so that the first buffer base 1001 is offset from the next buffer base 1001. Finally, the handling component 23 is operated to move the offset buffer base 1001 to the assembly fixture 105 at the end of the handling track. The intermittent driving component 104 drives the turntable 103 to rotate again to drive the next assembly fixture 105 without a buffer base 1001 placed thereon to the end of the handling track; moreover, during the handling process of the handling component 23, the lifting and offsetting component 22 resets to receive the next buffer base 1001 and drives the buffer base 1001 to rise and be offset, realizing continuous automatic feeding. In addition, the lifting and offsetting component 22 is set to drive a buffer base 1001 to rise by a specified height to be offset from the next buffer base 1001, the purpose of which is to provide a position for the handling component 23 to clamp the buffer base 1001, facilitating the handling component 23 to clamp the buffer base 1001 from the length side of the buffer base 1001. If two buffer bases 1001 are placed side by side, the handling component 23 will have no position to clamp the buffer base 1001.

[0030] Such as Figure 2As shown, the conveying component 21 includes a first support frame 211 and a belt conveying module 212 installed on the first support frame 211. After placing multiple buffer bases 1001 on the belt conveying module 212, they are conveyed, and the buffer bases 1001 are conveyed to the lifting and offsetting component 22 one by one. Among them, it also includes a belt driving module 213 for driving the operation of the belt conveying module 212. The belt driving module 213 is a prior art. In practice, a similar structure such as a driving motor driving a roller to rotate can be adopted. The belt of the belt conveying module 212 is wound around the roller to achieve driving, which will not be elaborated here. A guiding top plate 214 is provided on the top of the belt conveying module 212 for guiding the buffer base 1001 during the conveying process. The guiding top plate 214 is placed above the buffer base 1001 during the conveying process, so that the distance between the guiding top plate 214 and the top surface of the belt conveying module 212 is exactly the height of one buffer base 1001, or slightly greater than the height of one buffer base 1001, to prevent the buffer base 1001 from flipping during the conveying process of the buffer base 1001, affecting subsequent handling.

[0031] As Figures 3 - 4 shown, the lifting and offsetting component 22 includes a support seat 221 and a first cylinder 222 installed on the support seat 221 with its telescopic rod arranged upward. The end of the telescopic rod of the first cylinder 222 is equipped with a lifting seat 223 placed at the end of the belt conveying module 212 and used to drive the buffer base 1001 to rise. The lifting seat 223 has a feeding position that can only place one buffer base 1001. The feeding position on the lifting seat 223 is at the same horizontal position as the top surface of the belt conveying module 212, or lower than the top surface of the belt conveying module 212. After the belt conveying module 212 conveys the first buffer base 1001 to the feeding position on the lifting seat 223, the next buffer base 1001 is placed on the belt conveying module 212. At this time, the first cylinder 222 can be operated to control the lifting seat 223 to rise, so as to drive the buffer base 1001 to rise to a specified height, facilitating subsequent handling by the handling component 23. After the buffer base 1001 at the feeding position of the lifting seat 223 is carried away, control the lifting seat 223 to descend and reset to the initial position. After the belt conveying module 212 conveys the next buffer base 1001 to the feeding position of the lifting seat 223, control the lifting seat 223 to rise again.

[0032] In addition, a stopper 224 for blocking the buffer base 1001 conveyed to the discharging position is provided on the lifting seat 223, and a sensor 225 for sensing whether there is a buffer base 1001 on the lifting seat 223 is provided on the stopper 224; when the discharging position on the lifting seat 223 is at the same horizontal position as the top surface of the belt conveying module 212 or lower than the top surface of the belt conveying module 212, the belt conveying module 212 conveys the first buffer base 1001 to the lifting seat 223, and it is blocked by the stopper 224. When the conveyed buffer base 1001 is blocked to the discharging position and detected by the sensor 225, the first cylinder 222 can be controlled to operate, and the lifting seat 223 drives the buffer base 1001 to rise to a specified height, thereby improving the accuracy of conveying the buffer base 1001 by means of the stopper 224.

[0033] Furthermore, the lifting seat 223 is further equipped with a second cylinder 226 whose telescopic rod faces the discharging position and the moving direction of the telescopic rod is consistent with the length direction of the buffer base 1001 placed at the discharging position. There are two stoppers 224 on the lifting seat 223, which are respectively close to both ends of the discharging position. The second cylinder 226 is close to one of the stoppers 224, and the other stopper 224 is in a lying L shape, and one end of the buffer base 1001 placed at the discharging position is semi-surrounded by the L-shaped stopper 224. A push block 227 for pushing the buffer base 1001 to abut against the L-shaped stopper 224 to straighten it is installed at the end of the telescopic rod of the second cylinder 226. After the buffer base 1001 is conveyed to the lifting seat 223 and blocked by the stopper 224, the second cylinder 226 is operated to control the push block 227 to contact one end of the buffer base 1001, so as to push the other end of the buffer base 1001 to contact the L-shaped stopper 224, and the buffer base 1001 is straightened, further improving the accuracy of subsequent handling by the handling component 23.

[0034] Additionally, a guide block 228 for guiding the conveyed buffer base 1001 to the discharging position of the lifting seat 223 is further provided on the support seat 221; the guide block 228 cooperates with the guide top plate 214 to jointly guide the buffer base 1001 during the conveying process.

[0035] Further, the handling component 23 includes a second support frame 231 and a slide rail 232 arranged horizontally on the second support frame 231. A slider 233 is slidably provided on the slide rail 232. Under the action of the slide rail 232, the slider 233 can move horizontally on the second support frame 231. Among them, a material grabbing component capable of moving up and down is installed on the slider 233; the material grabbing component is placed directly above the lifting seat 223. When there is a buffer base 1001 at the material discharging position of the lifting seat 223, the lifting seat 223 can be controlled to rise to bring it to a specified height, and then the material grabbing component is controlled to move downward a specified distance and the material grabbing component is operated to clamp the buffer base 1001 placed at the material discharging position. Subsequently, the lifting seat 223 is simultaneously controlled to reset downward and the material grabbing component is controlled to reset upward, and then the slider 233 is driven to move horizontally on the second support frame 231 to transport the buffer base 1001 to the assembly position jig 105 placed at the end of the handling track, realizing the automatic feeding process of the buffer base 1001.

[0036] In order to enable the material grabbing component to automatically move up and down on the slider 233, a third air cylinder 235 with a telescopic rod arranged downward is installed on the slider 233, and a lifting plate 236 is provided at the end of the telescopic rod of the third air cylinder 235. The material grabbing component is installed on the lifting plate 236; when the third air cylinder 235 is operated, while controlling the lifting plate 236 to move up and down, the material grabbing component is driven to move up and down.

[0037] Preferably, the material grabbing component includes a jaw cylinder 237 installed on the lifting plate 236 with its actuating end arranged downward, and clamping blocks 238 for clamping the length sides of the buffer base 1001 are provided on both actuating ends of the jaw cylinder 237. The lifting plate 236 drives the jaw cylinder 237 and the clamping blocks 238 on both actuating ends to move downward a specified distance, so that the clamping blocks 238 are respectively placed on both sides of the length side of the buffer base 1001, and then the jaw cylinder 237 is operated to clamp the buffer base 1001 for subsequent handling. In addition, convex portions 239 extending towards each other are provided at the bottom ends of the two clamping blocks 238. After the buffer base 1001 is clamped by the two clamping blocks 238, the convex portions 239 will support the bottom of the buffer base 1001, making it more stable during the handling process and preventing the buffer base 1001 from falling. And, a relief groove 2310 for the convex portion 239 to be embedded is provided on the top surface of the lifting seat 223. After the lifting plate 236 drives the jaw cylinder 237 and the clamping blocks 238 on both actuating ends to move downward a specified distance, the convex portion 239 is embedded in the relief groove 2310. While the clamping blocks 238 clamp the buffer base 1001, the convex portion 239 is placed at the bottom of the buffer base 1001 through the relief groove 2310.

[0038] A pair of pressure rods 2311 are provided on the lifting plate 236, which respectively abut against both ends of the buffer base 1001 during the handling process. When the convex portion 239 is inserted into the relief groove 2310, the pressure rods 2311 just press against both ends of the buffer base 1001. During the handling of the buffer base 1001, by the cooperation of the pressure rods 2311 abutting against both ends of the buffer base 1001 and the convex portion 239 supporting the bottom of the buffer base 1001, the stability of the handling is further improved.

[0039] In order to drive the slider 233 to slide on the slide rail 232, the second support frame 231 is provided with a linearly driving module 234 arranged horizontally, and the movable end of the linearly driving module 234 is fixedly arranged with the slider 233; by operating the linearly driving module 234 to drive the slider 233 to slide horizontally, and then cooperating with the third cylinder 235 and the jaw cylinder 237, the buffer base 1001 is automatically handled. A pair of position sensors 2312 are provided on the second support frame 231, which are respectively placed at both ends of the slide rail 232 and used to sense the position of the slider 233. By sensing the position of the slider 233 through the position sensors 2312, the accuracy of the movement of the slider 233 is improved, and the precise handling of the buffer base 1001 is realized.

[0040] In summary, it can be seen that the present utility model has the excellent characteristics described above, so that it can enhance the efficiency that has never been achieved in the prior art during use and has practicality, becoming a product with extremely high practical value.

[0041] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
