Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, specifically a multi-station rotary hopper for automated production. Background Technology

[0002] In industrial production fields such as automated machining and electronic component assembly, multi-station rotary storage bins are commonly used workpiece transfer and storage devices. They are mainly used to realize batch storage of workpieces, multi-station switching, and automated transfer. They typically include a support frame, a rotatable turntable, and multiple workpiece stations evenly distributed on the turntable. Relying on the rotation of the turntable, workpieces at different stations are transferred to the picking, feeding, or processing stations, replacing the traditional manual transfer method. This effectively improves the automation level and production efficiency of the production line and is widely used in various continuous production scenarios.

[0003] However, when changing batches of workpieces in existing multi-station rotary hoppers, operators need to manually adjust the clamping distance of the three adjusting columns at each station using wrenches, screwdrivers, and other tools. This adjustment process is cumbersome, inefficient, and seriously affects the changeover speed of the production line. At the same time, in order to reduce the friction when picking up and placing workpieces, an appropriate gap is reserved between the adjusting columns and the workpieces. However, this gap causes the workpieces to shake and rub against each other during the rotation of the turntable, which in turn damages the surface precision of the workpieces. In addition, a large amount of residual cutting fluid adheres to the surface of the workpieces after machining. Directly storing workpieces with fluid not only easily causes oxidation and corrosion of the workpiece surface and the adhesion of impurities, affecting the quality of subsequent machining and assembly, but also causes the cutting fluid to flow everywhere, contaminating the internal structure of the hopper and surrounding production equipment, increasing the cost of equipment cleaning and maintenance.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 7 As shown, the multi-station rotary hopper for automated production according to the present invention includes a frame 1, a turntable 7 rotatably connected to the frame 1, and an adjustment structure 2 provided on the turntable 7; the adjustment structure 2 includes a guide component provided on the turntable 7, the turntable 7 is provided with the adjustment component, the guide component is used to guide the adjustment component, the turntable 7 is provided with a drive component, the drive component is used to drive the adjustment component to move, and a drive structure 3 is provided between the turntable 7 and the frame 1, the drive component and the drive structure 3 are used in conjunction.

[0022] Specifically, such as Figure 2 and Figure 6As shown, the guiding assembly includes a guide frame 201 and guide blocks 202. Multiple guide frames 201 are fixedly connected to the turntable 7. Three guide blocks 202 are slidably connected to the guide frame 201. Adjusting posts 205 are rotatably connected to the guide blocks 202. The adjusting assembly includes a drive ring 203 and drive grooves 204. A drive ring 203 is rotatably connected to the turntable 7. The drive ring 203 has three drive grooves 204. Each set of three adjusting posts 205 rolls into contact with the three drive grooves 204 on a drive ring 203. The driving assembly includes a first toothed ring 206, a second toothed ring 207, and a guide ring 208. The first toothed ring 206 is fixedly connected to the drive ring 203. The second toothed ring 207... 07 drives the first toothed ring 206 to rotate, which in turn drives the drive ring 203 to rotate. The drive groove 204 on the drive ring 203 drives the adjusting column 205. Under the guidance and constraint of the guide frame 201 and the guide block 202, the three adjusting columns 205 in each group synchronously close or open, quickly completing the workpiece clamping distance adjustment. The guide component effectively constrains the movement trajectory of the adjusting column 205, avoiding adjustment deviation that could cause the clamping to become loose or too tight. Multi-station synchronous adjustment is achieved by relying on the meshing of the toothed rings, eliminating the need for individual debugging at each station and greatly improving the efficiency of workpiece specification adaptation. The first toothed ring 206 is meshed with a second toothed ring 207, and a guide ring 208 is fixedly connected to the second toothed ring 207. The guide ring 208 is rotatably connected to the turntable 7.

[0023] Specifically, such as Figure 3 and Figure 7As shown, the drive structure 3 includes a connecting shaft 301 rotatably connected to the turntable 7 and a connecting rod 302 fixedly connected to the connecting shaft 301. The connecting rod 302 is fixedly connected to the second gear ring 207. A slide rod 303 is slidably connected to the connecting shaft 301. A fixed seat 304 is mounted on the frame 1. A slide block 305 is slidably connected to the fixed seat 304. A first drive member 306 is mounted on the slide block 305. The slide rod 303 is fixedly connected to the output shaft of the first drive member 306. A second drive member 307 is mounted on the fixed seat 304. The telescopic end of the second drive member 307 is fixedly connected to the slide block 305. The second drive member 307 is used to drive the slide block 305 to slide. A limiting structure 4 is provided between the slide rod 303 and the turntable 7. The limiting structure 4 includes a fixedly connected... The limiting ring 401 on the turntable 7 and the multiple limiting holes 402 arranged in a circumferential array on the limiting ring 401 are connected by the second driving member 307 receiving an electrical signal to drive the slide block 305 to slide upward along the fixed base 304, thereby driving the slide rod 303 to move upward synchronously, so that the limiting shaft 404 on the fixed plate 403 disengages from the limiting hole 402 on the limiting ring 401, releasing the synchronous locking state between the slide rod 303 and the turntable 7. At this time, the first driving member 306 starts to operate, driving the connecting shaft 301 and the connecting rod 302 to rotate, so that the second toothed ring 207 rotates. At this time, the turntable 7 will not rotate under the action of the fourth driving member 11, and can only adjust the clamping distance. The fixed plate 403 is fixedly connected to the slide rod 303, and the limiting shaft 404 is fixedly connected to the fixed plate 403. The limiting shaft 404 engages with one of the limiting holes 402.

[0024] Specifically, such as Figure 5 , Figure 7 and Figure 9 As shown, the frame 1 and adjusting column 205 are provided with a lifting structure 5. The lifting structure 5 includes two lead screws 501 rotatably connected to the frame 1 and an adjusting plate 502 threadedly connected to the lead screws 501. Three push rods 503 are fixedly connected to the adjusting plate 502. The third driving component 504 receives a command from the control module to drive the lead screws 501 to rotate, causing the adjusting plate 502 to move vertically upward, so that the push rods 503 pass through the corresponding through holes 506 on the turntable 7. The lifting plate 505 is on top. Under the thrust of the rod 503, it slides smoothly upward between the three adjusting columns 205, lifting the workpiece in the workstation as a whole, making it easy for the external robot arm to grasp. The lifting rod 503 is slidably connected to the frame 1. The turntable 7 is provided with a through hole 506 that works with the lifting rod 503. A lifting plate 505 is slidably connected between every three adjusting columns 205. Two third driving components 504 are installed on the frame 1, and the two third driving components 504 drive the two lead screws 501 to rotate respectively.

[0025] Specifically, such as Figure 1 and Figure 8 As shown, the frame 1 is equipped with a drying structure 6. The drying structure 6 includes a mounting frame 601 installed on the frame 1 and a heating tube 602 installed on the mounting frame 601. A duct 603 is installed between the mounting frame 601 and the frame 1. The robot arm picks up the workpiece after cutting and moves it to the drying station corresponding to the connecting frame 605. Then, the negative pressure fan 604 receives an electrical signal from the control module and starts to operate. The heating tube 602 in the mounting frame 601, together with the negative pressure fan 604, generates constant temperature hot air to evenly blow and dry the residual cutting fluid on the surface of the workpiece, the clamping blind area, and the corners, so as to avoid the cutting fluid corroding the workpiece. The surface of the workpiece is affected, which affects the subsequent processing accuracy and assembly quality. At the same time, it reduces the adhesion of impurities and improves the cleanliness of the finished workpiece. The water vapor and liquid waste liquid generated during the workpiece drying enter the air duct 603 with the airflow. Gas-liquid separation is achieved by the gas-liquid filter screen 606 arranged at an incline on the connecting frame 605. The liquid cutting fluid is collected along the inclined surface of the filter screen and discharged from the drain pipe 607. The dried gas is discharged to the outside by the negative pressure fan 604. The air duct 603 is equipped with a negative pressure fan 604 and a connecting frame 605. The gas-liquid filter screen 606 is installed at an incline on the connecting frame 605. The drain pipe 607 is fixedly connected to the bottom of the air duct 603.

[0026] Specifically, such as Figure 7 As shown, a third gear ring 8 is fixedly connected to the turntable 7, and a gear 10 meshes on the third gear ring 8. A connecting seat 9 is installed on the frame 1. After receiving the command from the control module, the fourth drive component 11 operates, driving the gear 10 to mesh with the third gear ring 8, thereby driving the turntable 7 to rotate at a constant speed on the frame 1 and smoothly completing the multi-station switching process. The fourth drive component 11 is installed on the connecting seat 9, and the gear 10 is installed on the output shaft of the fourth drive component 11.

[0027] In use, this invention is first assembled and deployed at the workpiece transfer station of an automated machining production line. An external control module establishes signal transmission links with the first drive component 306 (preferably a DC motor), the second drive component 307 (preferably a linear cylinder), the third drive component 504 (preferably a DC motor), and the fourth drive component 11 (preferably a worm gear reducer motor) via stable electrical connections. Each electrical connection node is reliably connected. The control module can issue start / stop, operation, and extension / retraction control commands to each drive component via these electrical connections. This centralized electrical control design enables the operation of each drive component... The coordinated operation of components enhances the synchronization and stability of the overall equipment operation. The fourth drive component 11 operates after receiving instructions from the control module, driving the gear 10 to mesh with the third gear ring 8, causing the turntable 7 to rotate uniformly on the frame 1, smoothly completing multi-station switching. When the limiting shaft 404 engages with the limiting hole 402, the rotation of the turntable 7 will cause the connecting shaft 301 to rotate together. When it is necessary to clamp and position workpieces of different diameters, the second drive component 307 receives an electrical signal to drive the slide block 305 to slide upwards along the fixed seat 304, causing the slide rod 303 to move upwards synchronously, thus aligning the fixed seat with the workpiece. The limiting shaft 404 on the fixed plate 403 disengages from the limiting hole 402 on the limiting ring 401, releasing the synchronous locking state between the slide rod 303 and the turntable 7. At this time, the first driving component 306 starts to operate, driving the connecting shaft 301 and the connecting rod 302 to rotate, causing the second gear ring 207 to rotate. Meanwhile, the turntable 7 will not rotate under the action of the fourth driving component 11, and can only adjust the clamping distance. The second gear ring 207 will drive the first gear ring 206 to rotate, and the first gear ring 206 will drive the driving ring 203 to rotate. The driving groove 204 on the driving ring 203 drives the adjusting column. 205. Under the guidance and constraint of the guide frame 201 and the guide block 202, the three adjusting columns 205 in each group synchronously retract or open, quickly completing the workpiece clamping distance adjustment. The guide component effectively constrains the movement trajectory of the adjusting column 205, avoiding clamping looseness or excessive tightness caused by adjustment deviation. Multi-station synchronous adjustment is achieved by relying on the meshing of the toothed ring, eliminating the need for individual debugging at each station, greatly improving the efficiency of workpiece specification adaptation and reducing manual debugging costs. At the same time, the workpiece can be clamped in advance before the turntable 7 rotates to prevent the workpieces from rubbing and scratching each other during transfer, protecting the workpiece machining surface accuracy and reducing the scrap rate. After adjusting the workpiece clamping distance, the robotic arm picks up the machined workpiece and moves it to the drying station corresponding to the connecting frame 605. Then, the negative pressure fan 604 starts operating upon receiving an electrical signal from the control module. The heating tube 602 inside the mounting frame 601, in conjunction with the negative pressure fan 604, generates constant-temperature hot air to evenly blow away and dry residual cutting fluid on the workpiece surface, in the clamping blind areas, and at the corners. This prevents the cutting fluid from corroding the workpiece surface and affecting subsequent machining accuracy and assembly quality, while also reducing impurities and improving the cleanliness of the finished workpiece. The water vapor and liquid waste generated during drying enter the air duct 603 with the airflow. Gas-liquid separation is achieved through the gas-liquid filter 606 arranged at an incline on the connecting frame 605. The liquid cutting fluid is collected along the inclined surface of the filter and discharged from the drain pipe 607. The drying gas is discharged to the outside through the negative pressure fan 604 to keep the drying station dry and clean, and to prevent water vapor from accumulating and shortening the service life of the device components. After drying, the robot places the workpiece in the work area enclosed by each set of adjusting columns 205, and automates the drying and feeding process, effectively improving the workpiece processing efficiency. When the turntable 7 transfers the workpiece to the preset lifting position, the third drive component 504 receives the command from the control module to drive the lead screw 501 to rotate, which in turn drives the adjusting plate 502 to move vertically upward, so that the push rod 503 passes through the corresponding through hole 506 on the turntable 7. Under the pushing force of the push rod 503, the lifting plate 505 slides smoothly upward between the three adjusting columns 205, lifting the workpiece in the position as a whole, making it easier for the external robot to grasp, improving the efficiency and accuracy of material handling, reducing production line delays caused by material handling errors, and realizing the full-process automated connection of workpiece from drying and transfer to material handling, further improving the production efficiency and intelligence level of the machining production line.
