Material conveying device on the automatic assembly line of aluminum inspection port inner and outer frames

Abstract

This utility model discloses a material conveying device and a transfer device for use on an automatic assembly line for inner and outer frames of aluminum inspection ports. The device is used to convert horizontally arranged products into vertically arranged products. The transfer device includes several inclined rollers, with a screw installed below each roller. Slide rods are provided on both sides of the screw, and a combined plate slidably connected to the slide rods, threaded with the screw, is used to push the horizontally arranged products. A limiting frame is provided at the pushing end of the combined plate, forming a vertical stacking area between the limiting frame and the rollers. The horizontally arranged products are pushed into the vertical stacking area by the combined plate, and a hook head extending from the top of the pushing plate pushes the workpiece. Because the hook head extends from the gap between the rollers, it does not affect the use of the rollers and improves the compactness of the structure. Through the movement of the combined plate, its hook head pushes the horizontally arranged workpieces down to the vertical stacking area for stacking, thus completing the conversion of the workpieces from horizontal to vertical arrangement.

Description

Technical Field

[0001] This utility model 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:

[0004] 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.

[0005] 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. Utility Model Content

[0006] The purpose of this invention is to provide a material handling device for automatic assembly lines of inner and outer frames of aluminum inspection ports, so as to solve the problem of workpiece reversal and stacking in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material handling device and a transfer device are used on an automatic assembly line for aluminum inspection port inner and outer frames to convert horizontally arranged products into vertically arranged products.

[0009] The transfer device includes several rollers arranged at an angle, a screw installed below the rollers, and slide rods on both sides of the screw. A combination plate that is threadedly connected to the slide rod is used to push the horizontally arranged products. A limiting frame is provided at the pushing end of the combination plate. The limiting frame and the rollers form a vertical stacking area. The horizontally arranged products are pushed into the vertical stacking area by the combination plate.

[0010] The guide component guides the horizontally arranged products into the vertically arranged stacking area.

[0011] Preferably, push plates are detachably installed at both ends of the combined plate, and the push plates have barbed heads extending from the gaps between the arranged rollers.

[0012] 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. A sheet metal frame is connected to the bottom of the mounting block, and a motor connected to the screw is installed on one side of the mounting block.

[0013] Preferably, the guide assembly includes an inner plate, an outer plate, and a guide rod. The inner plate is supported on the surface of the sheet metal frame, and the guide rod is connected between the two ends of the outer plate and the guide rod. The guide rod extends from the gap between the arranged rollers, and 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.

[0014] Preferably, a guide plate is installed on the top of the limiting frame, with an arc-shaped transition on the side near the limiting frame. The arc-shaped transition of the guide plate has an end face that is parallel to the roller. The arc-shaped transition end of the guide plate can further guide the workpiece to fall into the vertically arranged stacking area, avoiding instability in the stacking of materials in the vertically arranged stacking area.

[0015] Preferably, the parallel end face of the guide plate extends to more than half the distance of the roller. This extension of the parallel end face of the guide plate covers the roller, thus preventing the workpiece from tilting or detaching and further improving the guiding effect on the workpiece.

[0016] The technical solution of this utility model has the following beneficial effects:

[0017] 1. The hook head extending from the top of the push plate pushes the workpiece. Since the hook head extends from the gap between the rollers, it does not affect the use of the rollers and improves the compactness of the structure. After the combination plate moves, the hook head pushes the horizontally arranged workpieces down to the vertically arranged stacking area for stacking, thus completing the workpiece stacking from horizontal to vertical arrangement.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] refer to Figures 1-5 A material handling device for an automatic assembly line of inner and outer frames of aluminum inspection ports, comprising a transfer device 20, used to convert horizontally arranged products into vertically arranged products; the product refers to workpiece 50.

[0028] 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. A limit frame 216 is provided at the pushing end of the combination plate 209. The limit 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.

[0029] The two ends of the combination plate 209 are detachably equipped with push plates 210, and the push plates 210 have barbed heads 212 extending from the gaps between the arranged rollers 205.

[0030] 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.

[0031] refer to Figure 3 The roller 205 is equipped with mounting blocks 202 and inclined platforms 203 at both ends. The bottom of the inclined platform 203 has a support base 204 for raising the connection angle of the roller 205. The bottom of the mounting block 202 is connected to a sheet metal frame 201. A motor 207 connected to the screw 208 is installed on one side of the mounting block 202.

[0032] In the above scheme, the roller 205 can be easily installed at an angle between the mounting block 202 and the inclined platform 203 by raising the support base 204; the start of the motor 207 is used to control the rotation of the screw 208, thereby driving the combined plate 209 to move and push the material. The motor 207 is a reduction type motor.

[0033] refer to Figure 2 In the diagram, the area marked A is the mounting surface for this product, which is installed at an angle.

[0034] Example 2:

[0035] refer to Figures 1-3The 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. 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.

[0036] In the above scheme, during the process of the 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, thereby reserving bottom space. It should be noted here that: Figure 1 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.

[0037] Preferred Solution Reference Figure 2 The top of the limit frame 216 is equipped with a guide plate 217. The guide plate 217 near the side of the limit 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.

[0038] The parallel end face of the guide plate 217 extends to more than half the distance of the roller 205.

[0039] In a preferred embodiment, 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.

[0040] The specific implementation process of this utility model is as follows:

[0041] When the screw 208 rotates, the threaded sleeve 211 interacts with the screw 208, the combination plate 209 slides on the slide bar 218, and the horizontally stacked workpieces 50 are pushed out by the push plates 210 at both ends of the combination plate 209. The barb head 212 extending from the top of the push plate 210 pushes the workpieces 50. After the combination plate 209 moves, its barb head 212 pushes the horizontally stacked workpieces 50 down to the vertically stacked material area 219 for stacking, thereby completing the process of stacking the workpieces 50 from horizontal to vertical arrangement.

[0042] During the process of the 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 workpiece 50 at the front 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 arc transition end of the guide plate 217 can further guide the workpieces 50 to fall into the vertically arranged stacking area 219, avoiding instability in the stacking of the vertically arranged stacking area 219.
