Description

TECHNICAL FIELD

[0001] The utility model relates to packaging jar body welding processing technical field especially, a kind of feeding mechanism for packaging jar body welding equipment. BACKGROUND

[0002] Packaging jar body such as food jar is constituted by box cover, jar body and box bottom, when producing food jar, box cover, jar body and box bottom are produced separately, then the three are combined together to make food jar. Among them, the jar body is generally welded by welding equipment to roll the plate material into cylindrical shape, and then welded at the joint position. In the prior art, the appearance defects of the packaging jar also need to be detected. The appearance defects are generally scratches and scratches, dents and pits, stains and oil stains, etc. Among them, the appearance detection step of the packaging jar is generally after the jar body welding processing is completed, it is transferred to the corresponding appearance detection equipment for detection, such as CN202420263669.9 (authorized announcement number: CN221976712U) Chinese utility model "a food jar body defect visual detection device" has made similar disclosure.

[0003] But the existing packaging jar welding processing and appearance defect detection process still has certain deficiencies: first, the appearance detection is carried out after the jar body welding processing is completed. If the appearance defect is found at this time, it means that the previous welding and other processing procedures have invested manpower, material resources and time cost. These defective jars may need to be reworked or even scrapped, causing waste of resources and increase of production cost. Secondly, since the appearance detection link is independent after the welding and other processing process, it forms a relatively independent step, which needs to be specially arranged for detection. This prolongs the entire production cycle to some extent, reduces the production efficiency, may cause production delay, and affects the delivery time of products.

[0004] If the appearance detection step is placed before the jar body welding processing, the above-mentioned time-consuming and labor-intensive defects also exist. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problems in the prior art, and provides a feeding mechanism for packaging jar body welding equipment, which can effectively optimize the packaging jar welding processing and appearance detection process, and improve the production efficiency.

[0006] The utility model solves the above technical problems by adopting the following technical scheme: a feeding mechanism for packaging jar body welding equipment, comprising:

[0007] A feeding platform is used to place the plate to be welded and processed.

[0008] A conveying device includes a rack and a feeding roller assembly arranged on the rack, the feeding roller assembly is used to convey the plate placed on the feeding platform to the welding processing position.

[0009] It also includes a visual inspection device for detecting appearance defects in the sheet material being conveyed forward by the feed roller assembly.

[0010] To more clearly display some defects on the board so that the visual inspection equipment can capture or identify them more accurately, the frame is provided with a reflector with an opening facing the surface of the board to be inspected. A light source is provided inside the reflector. The visual inspection device is located outside the reflector. The reflector is also provided with a light-transmitting opening for the detection light of the visual inspection device to pass through.

[0011] The visual inspection device can be one of an infrared inspection device, an optical imaging-based visual inspection device, or a laser imaging-based visual inspection device. Preferably, the visual inspection device is an infrared inspection device, which includes an infrared emitter for emitting infrared light and an infrared receiver for receiving reflected infrared light.

[0012] Considering the heat generated by the light source, in order to cool down the substrate of the light source, the reflector is also provided with a cooling channel for cooling the substrate of the light source. The reflector is also provided with an inlet pipe for allowing external cooling fluid to enter into the cooling channel and an outlet pipe for allowing fluid to exit from the cooling channel. The substrate is fixed on the cooling channel.

[0013] In order to more effectively cool the substrate of the light source, the cooling channels are arranged circumferentially around the opening of the reflector.

[0014] To facilitate the inspection or replacement of the reflector and the light source and other components mounted thereon, a mounting bracket is also included, which extends along the width of the frame. One end of the mounting bracket is rotatably connected to the frame in the vertical direction. The reflector is mounted on the mounting bracket, and the opening of the reflector faces downward.

[0015] To ensure the reliability and stability of the mounting bracket after it is fastened to the frame, the other end of the mounting bracket away from its rotatable connection with the frame is locked to the frame by a locking assembly.

[0016] To ensure that the sheet metal can be stably conveyed forward in the appearance defect detection area, a conveying roller extending along the width direction of the frame is provided on the frame corresponding to the position below the mounting frame. The bottom of the mounting frame also has at least two rollers arranged at intervals along the length direction of the mounting frame, with each roller facing the conveying roller vertically.

[0017] To accommodate different sizes of sheet metal, each of the rollers is adjustable and can slide along the length of the mounting frame.

[0018] To ensure that the sheet metal can remain flat in the appearance defect detection area, a lower guide block is provided on the frame below the reflector, and an upper guide block is provided at the bottom opening of the reflector. The upper guide block and the lower guide block are opposite each other in the vertical direction, and a gap is defined between them for the sheet metal to pass through.

[0019] Compared with existing technologies, the advantages of this utility model are as follows: First, by inspecting the appearance of the sheet metal during the welding loading process, defects such as surface scratches and dents can be detected in time before the sheet metal enters the welding process. This allows for timely countermeasures, reducing rework and scrap costs caused by substandard tank appearance and improving the utilization efficiency of production resources. Second, by advancing the appearance inspection step to the welding loading process, the inspection is closely integrated with welding and other processing steps, reducing waiting and transfer time between the inspection and other processes, optimizing the production flow, and improving the continuity and smoothness of production, thereby effectively improving processing efficiency. Furthermore, by distributing the appearance inspection process within the welding loading process, the inspection equipment can work collaboratively with the welding equipment, performing inspections simultaneously with sheet metal loading. This avoids concentrated use and idleness of the inspection equipment, improving its utilization rate, fully leveraging its efficiency, and reducing equipment investment costs.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0029] Figures 1-7 A preferred embodiment of the feeding mechanism for a packaging can welding equipment of the present invention is shown. The feeding mechanism for a packaging can welding equipment includes a feeding platform 10, a conveying device, and a vision inspection device 40.

[0030] The feeding platform 10 is used to store or temporarily place the plate a to be welded. Specifically, the feeding platform 10 has four vertically extending material rods 11, which correspond to the four corners of the plate a respectively. The upper part of each material rod 11 is designed as an L-shaped structure that matches the corner of the plate a, thereby limiting the position of the plate a.

[0031] The conveying device includes a frame 20 and a feeding roller assembly 22 mounted on the frame 20. The frame 20 extends along the conveying direction of the sheet material a. Multiple feeding roller assemblies 22 can be arranged sequentially along the extension direction of the frame 20, thereby conveying the sheet material a placed on the feeding platform 10 to the welding processing position. The welding processing position is located at the end of the conveying device. The feeding roller assembly 22 can adopt a conventional feeding roller structure for conveying sheet material a in the prior art. The feeding roller assembly 22 generally includes a drive mechanism, a drive roller, and a driven roller. The drive roller is driven to rotate by a drive mechanism such as a motor, and propels the sheet material a forward through friction with it. The surface material of the drive roller may vary depending on the conveying requirements, such as rubber or polyurethane, to increase friction and ensure stable conveying of the sheet material a. The driven roller mainly plays a supporting and guiding role, rotating with the drive roller to keep the sheet material a stable during conveying. The number and distribution of the feeding roller assemblies 22 depend on the design of the feeding roller assembly 22 and the application scenario.

[0032] A visual inspection device is used to detect appearance defects in the sheet material a conveyed forward by the feed roller assembly 22. Specifically, it can be mounted on a frame 20 via a support bracket, with the visual inspection device positioned above the frame 20. The visual inspection device can be one of an infrared detection device, an optical imaging-based visual inspection device 40, or a laser imaging-based visual inspection device 40. In a preferred embodiment, the visual inspection device 40 is an infrared detection device, which includes an infrared emitter for emitting infrared light and an infrared receiver for receiving reflected infrared light. Defects on the surface of sheet material a, such as scratches and pits, alter the surface roughness and shape of sheet material a. Changes in surface roughness affect the emissivity and reflectivity of sheet material a to infrared light. Pits cause multiple reflections and scattering of light internally, altering the propagation path and intensity of infrared radiation.

[0033] The top of the frame 20 is also equipped with a hinged mounting bracket 30, which extends along the width of the frame 20. A reflector 34, also elongated along the width of the frame 20, is mounted on the mounting bracket 30. A light source 35 is mounted on the reflector 34. The main body of the reflector 34 has a U-shaped cross-section, with its opening facing the surface of the plate a to be inspected. This allows light emitted from the light source 35 to be reflected onto the surface of the plate a, making defects on the plate a more clearly visible and enabling the visual inspection equipment to more accurately capture or identify them. The aforementioned visual inspection device 40 is located outside the reflector 34. The reflector 34 also has a corresponding light-transmitting opening 343 for the inspection light from the visual inspection device 40 to pass through. This light-transmitting opening 343 is a strip-shaped opening extending along the width of the frame 20, with its length slightly larger than the width of the plate a along the frame 20. One end of the mounting bracket 30 has a support arm 31 with a shaft hole 310. A rotating shaft 24, corresponding to the shaft hole 310, is provided on the frame 20 and can pass through the shaft hole 310. The extending direction of the rotating shaft 24 is the same as the extending direction of the frame 20. Therefore, the mounting bracket 30 can be rotated upwards or downwards around the rotating shaft 24. When the mounting bracket 30 is engaged with the frame 20, both the mounting bracket 30 and the reflector 34 mounted on it extend horizontally, with the opening of the reflector 34 facing downwards. By configuring the mounting bracket 30 for mounting the reflector 34 as a rotating structure, it is convenient to inspect or replace the reflector 34 and components such as the light source 35 mounted on it.

[0034] See Figure 1When the mounting bracket 30 is engaged relative to the frame 20, the end of the mounting bracket 30 furthest from its rotatable connection with the frame 20 is locked to the frame 20 via a locking assembly 37, thereby ensuring the reliability and stability of the mounting bracket 30 after engagement with the frame 20. The locking assembly 37 can be a conventional latch lock, which typically consists of a movable latch and a fixed latch seat. When the mounting bracket 30 is engaged, the latch is flipped down, causing it to engage tightly with the latch seat, thus achieving locking, and the locked state is maintained by the interference of the mechanical structure.

[0035] A lower guide block 23 is also provided on the frame 20 below the reflector 34, and an upper guide block 36 is provided at the bottom opening of the reflector 34. The upper guide block 36 is located on the side of the bottom opening of the reflector 34 adjacent to the feeding platform 10, that is, the side for the incoming material of the sheet a. The upper guide block 36 and the lower guide block 23 are opposite each other in the vertical direction. The two opposing walls of the upper guide block 36 and the lower guide block 23 are both flat, and a gap is defined between the two opposing walls of the upper guide block 36 and the lower guide block 23 for the sheet a to pass through. The side of the upper guide block 36 facing the incoming material of the sheet a has a first guide surface extending obliquely upward, and the side of the lower guide block 23 facing the incoming material of the sheet a has a second guide surface extending obliquely downward. The above-mentioned first guide surface and second guide surface can effectively guide the sheet a into the gap between the upper guide block 36 and the lower guide block 23, ensuring that the sheet a can be kept in a flat state in the appearance defect detection area.

[0036] A conveyor roller 21 extending along the width direction of the frame 20 is provided on the frame 20, corresponding to the position below the mounting frame 30. The conveyor roller 21 can be driven to rotate by a corresponding motor. The bottom of the mounting frame 30 also has at least two rollers 33 arranged at intervals along the length direction of the mounting frame 30. Each roller 33 is vertically opposite to the conveyor roller 21 and contacts the upper and lower sides of the plate a, respectively, to ensure that the plate a can be stably conveyed forward in the appearance defect detection area. Specifically, the rollers 33 can be rubber wheels. Each roller 33 is slidably mounted on the mounting frame 30 through a connecting frame 331. The mounting frame 30 has a groove 32 extending along its length direction. The bottom of the connecting frame 331 has a slider 332 adapted to the groove 32. The connecting frame 331 is slidably constrained in the groove 32 by the slider 332. The above-mentioned connection structure design of the rollers 33 allows each roller 33 to slide and adjust along the length direction of the mounting frame 30, thereby adapting to plates a of different sizes.

[0037] Considering the heat generated by the light source 35, a cooling channel 340 is provided inside the reflector 34 to cool the substrate (not shown in the attached figure) used for mounting the light source 35. To more effectively cool the substrate, the cooling channel 340 can be designed to be circumferentially arranged around the opening of the reflector 34, with the substrate of the light source 35 correspondingly positioned at the opening. The cooling channel 340 can be formed by the reflector 34 itself or by an additional water pipe that is in close contact with the reflector 34. The reflector also has an inlet pipe 341 for allowing external cooling fluid to enter the cooling channel 340 and an outlet pipe 342 for discharging fluid from the cooling channel 340. In this embodiment, the substrate of the light source 35 generally refers to a mounting plate used for mounting or attaching a light source such as an LED strip.

[0038] This embodiment inspects the appearance of the sheet metal during the welding loading process. This allows for the timely detection of defects such as surface scratches and dents before the sheet metal enters the welding process, enabling prompt corrective action and reducing rework and scrap costs due to substandard tank appearance. This improves the efficiency of production resource utilization. Secondly, by advancing the appearance inspection to the welding loading process, inspection is closely integrated with welding and other processing steps, reducing waiting and transfer time between inspection and other processes. This optimizes the production flow, improves production continuity and smoothness, and effectively increases processing efficiency. Furthermore, distributing the appearance inspection process within the welding loading process allows the inspection equipment to work collaboratively with the welding equipment, performing inspections simultaneously with sheet metal loading. This avoids concentrated use and idleness of inspection equipment, increasing its utilization rate, maximizing its efficiency, and reducing equipment investment costs.
