Description

Technical Field

[0001] This invention belongs to the field of automation technology, specifically relating to a material conveying device used on an automatic assembly line for the inner and outer frames of aluminum inspection ports. Background Technology

[0002] In automated assembly lines for aluminum access panels (such as manhole covers and access doors), efficient, stable, and orderly material handling is crucial for ensuring production rhythm and product quality. Traditional manual or semi-automatic feeding methods often suffer from low efficiency, high labor intensity, poor workpiece alignment, and potential for misalignment or jamming at subsequent workstations, making them unsuitable for modern, large-scale production. Especially when it's necessary to precisely transform a large number of individual workpieces (such as frame profiles and connectors) from their initial scattered or simple arrangement into a specific stacking configuration (such as neat vertical stacking) and continuously and reliably supply them to core workstations such as stamping, riveting, or assembly, higher demands are placed on the automation level, reliability, and spatial layout optimization of the conveying device.

[0003] In the prior art: 1. Low efficiency in workpiece aggregation and arrangement: Workpieces initially entering the conveyor line may be in a horizontally dispersed state, requiring efficient aggregation and arrangement into groups to prepare for subsequent form transformation.

[0004] 2. Poor reliability of form conversion: It is a technical challenge to stably and without damage convert horizontally arranged workpieces into a vertical stacking state suitable for subsequent dense storage and single-piece retrieval, and to prevent the stack from becoming loose or collapsing.

[0005] 3. Space Compactness and Continuity Requirements: Assembly lines typically have limited space, requiring a compact layout and smooth connections in the conveying, stacking, and feeding processes to achieve continuous operation. Summary of the Invention

[0006] The purpose of this invention is to provide a material conveying device for use on an automated assembly line of inner and outer frames of aluminum inspection ports, so as to solve the problem of automated production in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A material conveying device for an automatic assembly line of inner and outer frames of aluminum inspection ports includes a workbench, a stamping area next to the workbench, and further includes; A transfer device is installed near the stamping area to convert horizontally arranged products into vertically arranged products. The transfer device includes several rollers arranged at an angle, with a screw installed below each roller. Slide rods are provided on both sides of the screw, and a combination plate that is threadedly connected to the slide rod is used to push the horizontally arranged products. Push plates are detachably installed at both ends of the combination plate, and a barb extending from the gap between the rollers is provided on the top of the push plate. A limiting frame is provided at the pushing end of the combination plate, and a vertical stacking area is formed between the limiting frame and the roller. The horizontally arranged products are pushed into the vertical stacking area by the combination plate. The transport device, located away from the stamping area and close to the transfer device, is used to transport horizontally arranged products to the transfer device. The pushing device is located inside the workbench and near the bottom of the vertically stacked material area. The pushing device is used to push the products in the vertically stacked material area to the stamping area for stamping operations.

[0008] Preferably, an mounting block and a ramp are respectively installed at both ends of the roller. The bottom of the ramp has a support base for raising the connection angle of the roller. The support base is supported and installed on the surface of the workbench. A sheet metal frame is connected to the bottom of the mounting block and is connected to the workbench. A motor connected to the screw is installed on one side of the mounting block.

[0009] Preferably, the guide component guides the horizontally arranged products into the vertically arranged stacking area; The guiding assembly includes an inner plate, an outer plate, and guide rods. The inner plate is supported on the surface of the sheet metal frame, and the outer plate is supported on the surface of the worktable. Guide rods are connected between the two ends of the outer plate and the guide rods. The guide rods extend from the gaps between the arranged rollers. The bottom product in the vertically arranged stacking area is supported on the surface of the outer plate and the bottom of the limiting frame.

[0010] Preferably, a guide plate is installed on the top of the limiting frame, and the guide plate near the side of the limiting frame has an arc transition, and the arc transition of the guide plate has an end face that is parallel to the roller.

[0011] Preferably, the plate extends to a distance more than half the length of the roller from the end face parallel to the plate.

[0012] Preferably, the transport device includes a mounting arm and a long leg frame. The mounting arm is supported on the ground by the long leg frame. Drive wheels are installed at both ends of the long leg frame, and a conveyor belt is installed on the drive wheels. The conveyor belt is parallel to the roller.

[0013] Preferably, an extension stop is installed near the downwardly inclined end of the conveyor belt; the extension stop extends above the roller.

[0014] Preferably, the pushing device includes a pushing bar for pushing products from the vertically arranged stacking area into the stamping area. A corner plate is installed at the bottom of the pushing bar, an L-plate is installed at the bottom of the corner plate, a slider is installed at the bottom of the L-plate, a slide rail is slidably mounted below the slider, a connecting plate fixed in the workbench is installed below the slide rail, a conveyor wheel with a belt is rotatably connected to the connecting plate, and the slider and the belt are fixedly connected by bolts.

[0015] Preferably, a pusher head is connected below the pusher bar, one end of the pusher head has a contour that conforms to the shape of the workpiece, and the other end of the pusher head has a connector that is detachably connected to the pusher bar.

[0016] The technical solution of this invention has the following beneficial effects: 1. A conveyor belt parallel to the rollers can smoothly transport a group of horizontally arranged workpieces on its surface to the transfer device.

[0017] 2. The inclined rollers allow horizontally stacked products to slide in an inclined direction, thus gathering multiple stacked products together to form a pile of workpieces. Through the movement of the combination plate, its hook heads push the horizontally arranged workpieces down to the vertical stacking area for stacking, thereby completing the process of moving the workpieces from horizontal to vertical arrangement. In the vertical stacking area, the workpieces are blocked by the limit frames at both ends, preventing them from becoming loose.

[0018] 3. When the slider moves, the pusher bar will push out one of the workpieces in the vertically arranged stacking area, and the pushed-out workpiece will be pushed into the stamping area for stamping. Since there will be a hollow area below the pushed-out workpiece, other workpieces will fall due to gravity. When the pusher bar pushes out the workpiece, the slider will immediately return until the stamping area completes the stamping. Then the slider will move again to perform the next push operation, and so on in a cycle. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0032] Example 1: refer to Figures 1-8 A material conveying device for an automatic assembly line of inner and outer frames of aluminum inspection ports includes a workbench 10, a stamping area 101 next to the workbench 10, and also includes; The transfer device 20 is located near the stamping area 101 and is used to convert horizontally arranged products into vertically arranged products; the product refers to the workpiece 50. The transfer device 20 includes several rollers 205 arranged at an angle. A screw 208 is installed below the rollers 205. Slide rods 218 are provided on both sides of the screw 208. A combination plate 209 that is threadedly connected to the slide rods 218 and is used to push the horizontally arranged products. Pushing plates 210 are detachably installed at both ends of the combination plate 209. A barb head 212 extending from the gap between the rollers 205 is above the pushing plate 210. A limiting frame 216 is provided at the pushing direction end of the combination plate 209. The limiting frame 216 and the rollers 205 form a vertical stacking area 219. The horizontally arranged products are pushed into the vertical stacking area 219 by the combination plate 209. In the above scheme, several rollers 205 are arranged at an angle, and each roller 205 is connected to the others by a transmission belt 206. Each roller 205 needs to be equipped with a geared motor (not shown in the figure, usually the last or first roller 205 is connected to the output end of the motor). When one roller 205 rotates, its transmission belt 206 will drive each roller 205 to rotate, thereby synchronously driving each roller 205 to rotate to transport the workpiece 50. The angled arrangement of the rollers 205 allows horizontally stacked products to slide in the angled direction, thereby gathering multiple stacked products together to form a pile of workpieces 50. A threaded sleeve 211 that mates with a screw 208 is installed at the center of the combination plate 209. When the screw 208 rotates, the threaded sleeve 211 interacts with the screw 208, and the combination plate 209 slides on the slide bar 218. The horizontally stacked workpieces 50 are pushed out by the push plates 210 at both ends of the combination plate 209. The hook heads 212 extending from the top of the push plates 210 push the workpieces 50. Since the hook heads 212 extend from the gaps between the rollers 205, they do not affect the use of the rollers 205, and at the same time improve the compactness of the structure. After the combination plate 209 moves, its hook heads 212 push the horizontally arranged workpieces 50 down to the vertical stacking area 219 for stacking, thus completing the process of moving the workpieces 50 from horizontal to vertical arrangement. The workpieces 50 in the vertical stacking area 219 are blocked by the limit brackets 216 at both ends, so the workpieces 50 will not become loose in the vertical stacking area 219.

[0033] The roller 205 has mounting blocks 202 and inclined platforms 203 installed at both ends. A support base 204 at the bottom of the inclined platform 203 is used to raise the connection angle of the roller 205. The support base 204 is supported and installed on the surface of the worktable 10. A sheet metal frame 201 is connected to the bottom of the mounting block 202 and is connected to the worktable 10. A motor 207 connected to a screw 208 is installed on one side of the mounting block 202. The increased height of the support base 204 allows the roller 205 to be easily tilted and installed between the mounting block 202 and the inclined platform 203. The motor 207 is a geared motor used to control the rotation of the screw 208, thereby driving the combined plate 209 to move and push materials.

[0034] Preferred Solution Reference Figure 3 and Figure 6 The guide assembly guides the horizontally arranged products into the vertically arranged stacking area 219. The guide assembly includes an inner plate 213, an outer plate 214, and a guide rod 215. The inner plate 213 is supported on the surface of the sheet metal frame 201, and the outer plate 214 is supported on the surface of the worktable 10. The guide rod 215 is connected between the two ends of the outer plate 214 and the guide rod 215. The guide rod 215 extends from the gap between the arrangement rollers 205. The bottom product in the vertically arranged stacking area 219 is supported on the surface of the outer plate 214 and the bottom of the limiting frame 216. For details of the preferred implementation scheme, please refer to [link / reference]. Figure 3 During the process of horizontally arranged workpieces 50 being pushed down to the vertically arranged stacking area 219 for stacking, the workpieces 50 move to the bend of the guide rod 215. The bend of the guide rod 215 transitions into the vertically arranged stacking area 219 in an arc shape. Therefore, the foremost workpiece 50 of the horizontally arranged workpieces 50 being pushed will be gradually transitioned by the guide rod 215 and fall stably into the vertically arranged stacking area 219. The workpiece 50 at the bottom of the vertically arranged stacking area 219 will be supported on the surface of the outer plate 214 and the bottom of the limiting frame 216, thus reserving bottom space to facilitate the subsequent pushing device 40 to gradually push the workpieces 50 of the vertically arranged stacking area 219 into the stamping area 101 for stamping. It should be noted here that: Figure 5 There are two limit frames 216 marked in the middle. Although they are not exactly the same in shape, their function is to block the workpieces 50 in the vertically arranged stacking area 219.

[0035] Further references Figure 3 The top of the limiting frame 216 is equipped with a guide plate 217. The guide plate 217 near the side of the limiting frame 216 has an arc transition, and the arc transition of the guide plate 217 has an end face that is parallel to the roller 205. The parallel end face of the guide plate 217 extends to more than half the distance of the roller 205.

[0036] In a further implementation, the arc-shaped transition end of the guide plate 217 can further guide the workpiece 50 to fall into the vertically arranged stacking area 219, avoiding instability in the stacking of materials in the vertically arranged stacking area 219. The parallel end face of the guide plate 217 extends to cover the roller 205, thereby preventing the workpiece 50 from tilting and detaching, and further improving the guiding effect on the workpiece 50.

[0037] Example 2: refer to Figure 1 , Figure 2 , Figure 4 The transport device 30 is located away from the stamping area 101 and close to the transfer device 20, and is used to transport horizontally arranged products to the transfer device 20. The transport device 30 includes a mounting arm 301 and a long leg frame 304. The mounting arm 301 is supported on the ground by the long leg frame 304. Drive wheels 302 are installed at both ends of the long leg frame 304. A conveyor belt 303 is installed on the drive wheels 302. The conveyor belt 303 is parallel to the roller 205. The above scheme is combined in detail Figure 1 and Figure 2 As can be seen, workpieces 50 are arranged in groups, that is, horizontally distributed workpieces 50. This grouping of workpieces 50 requires manual stacking or is uniformly stacked using a robotic arm (in automated production lines, robotic arms are used for stacking). The conveyor belt 303, parallel to the roller 205, smoothly transports the horizontally arranged workpieces 50 from its surface to the transfer device 20, which is the surface of the roller 205. A geared motor needs to be installed on one of the drive wheels 302 to drive the drive wheel 302 to rotate and transport the workpieces 50 via the conveyor belt 303. The geared motor is not described in detail here.

[0038] Further reference Figure 4 An extension stop 305 is installed at the downward-sloping end near the conveyor belt 303; the extension stop 305 extends above the roller 205.

[0039] In a further embodiment, since both the transfer device 20 and the transport device 30 are set at an angle, the workpiece 50 will move towards the angled end. The extension stop 305 blocks the workpiece 50, which can prevent the workpiece 50 from slipping off the transfer device 20 and the transport device 30. The extension length of the extension stop 305 is one-third of the total length of the transfer device 20. When the conveyor belt 303 transports the workpiece 50 to the surface of the roller 205, the extension stop 305 is always blocking the workpiece 50, which can ensure that the workpiece on the transport device 30 smoothly enters the transfer device 20.

[0040] Example 3: refer to Figure 2 and Figure 9 The pushing device 40 is located inside the workbench 10 and near the vertically arranged stacking area 219. The pushing device 40 is used to push the products in the vertically arranged stacking area 219 to the stamping area 101 for stamping operations.

[0041] The pushing device 40 includes a pushing bar 401, which is used to push the products in the vertically arranged stacking area 219 into the stamping area 101. A crank plate 404 is installed at the bottom of the pushing bar 401. An L plate 405 is installed at the bottom of the crank plate 404. A slider 406 is installed at the bottom of the L plate 405. A slide rail 408 is slidably provided below the slider 406. A connecting plate 407 fixed in the worktable 10 is installed below the slide rail 408. A conveyor wheel 409 with a belt is rotatably connected to the connecting plate 407. The slider 406 is fixedly connected to the belt by bolts. In the above scheme, there are two transport wheels 409. One of the transport wheels 409 is connected to the output end of a geared motor (the geared motor is not shown in the figure). When one transport wheel 409 rotates, the other rotates synchronously under the action of a belt. The belt drives the slider 406 to slide on the slide rail 408. The sliding direction is towards the stamping area 101. When the slider 406 moves, the pusher bar 401 will push out one of the workpieces 50 in the vertically arranged stacking area 219. The pushed-out workpiece 50 will be pushed into the stamping area 101 for stamping (no protection is provided during the stamping process). Since there will be a hollow area below the pushed-out workpiece 50, other workpieces 50 will fall due to gravity. When the pusher bar 401 pushes out the workpiece, the slider 406 will immediately return until the stamping area 101 completes the stamping. Then the slider 406 will move again to perform the next pushing operation, and so on in a cycle. It is worth noting that the forward and reverse rotation of slider 406 requires the use of a geared motor and frequency converter control to achieve forward and reverse rotation through frequency and phase sequence adjustment; it can also be achieved through PLC control system, DC motor PWM control and relay / contactor logic switching.

[0042] Further reference Figure 10 Below the pusher bar 401 is a pusher head 402. One end of the pusher head 402 has a contour that fits the shape of the workpiece 50, and the other end of the pusher head 402 has a connector head 403 that can be detachably connected to the pusher bar 401.

[0043] In a further implementation scheme, a connector 403 at one end of the pusher head 402 is inserted below the pusher bar 401. The connector 403 and the pusher bar 401 have concentric holes, and bolts are installed in the holes to complete the installation of the pusher head 402. The pusher head 402 is designed to fit the outline of the workpiece 50, making the pusher process smoother and more efficient.

[0044] The specific implementation process of this invention is as follows: Step 1: The robotic arm grabs the horizontally arranged workpieces 50 and places them on the surface of the conveyor belt 303. The conveyor belt 303 transports the workpieces to the surface of the roller 205. Step 2: By starting the motor 207, the horizontally stacked workpieces 50 are pushed out by the push plates 210 at both ends of the combination plate 209. The barb heads 212 extending from the top of the push plates 210 push the workpieces 50, pushing them down to the vertically stacked material area 219 for stacking. Step 3: When the transport wheel 409 rotates, the other wheel rotates synchronously under the action of the belt. The belt drives the slider 406 to slide on the slide rail 408. The sliding direction is towards the stamping area 101. When the slider 406 moves, the pusher bar 401 will push out one of the workpieces 50 in the vertically arranged stacking area 219. The pushed-out workpiece 50 will be pushed into the stamping area 101 for stamping. When the pusher bar 401 pushes out the workpiece, the slider 406 will immediately return until the stamping area 101 completes the stamping. Then the slider 406 will move again to perform the next push operation, and so on in a repetitive cycle.
