Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a novel appearance inspection machine. Background Technology

[0002] After processing, products (such as metal parts in mobile phones or computers) generally need to be inspected for their appearance and dimensions to ensure the quality of the metal parts and avoid the presence of defective products among good ones. There are two main inspection methods. One is manual inspection, or inspection using simple measuring fixtures such as plug gauges and magnifying glasses. This method relies entirely on manual labor and experience, requiring a high level of skill from the operator, and is less efficient and accurate. The second method uses inspection equipment, combined with a visual inspection camera to collect data and automatically inspect the parts. However, some parts require inspection of multiple surfaces, dimensions, and various appearance defects. After inspection, the parts need to be classified and placed according to the type of defect. This is generally done by blowing, as illustrated by the Chinese utility model patent "Dual Rotary Automatic Visual Inspection Equipment" (authorization announcement number: CN222152953U). Although this method is low-cost, its application is limited. For example, it is not suitable for heavy parts, and the blowing method can easily result in parts not being blown away or even being blown into other hoppers, leading to unsatisfactory sorting results.

[0003] The purpose of this invention is to provide a novel appearance inspection machine with other material dispensing devices. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a new type of appearance inspection machine with a reasonable structural design. It can perform relatively comprehensive visual inspection of products through multiple vision inspection devices, making the inspection more comprehensive and highly automated. It is also equipped with a special material sorting device to sort the materials according to the type of defect of the product, which facilitates rework and repair in subsequent processes.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a novel appearance inspection machine is provided, including a machine base and a turntable disposed on the machine base, multiple visual inspection devices for detecting product appearance defects, a feeding device, a discharging device, a distributing device, and a row of distributing bins. The turntable is provided with multiple tooling for placing products, and the multiple visual inspection devices are arranged at intervals around the turntable.

[0006] One row of the material distribution bins is located on one side of the machine.

[0007] The material distribution device includes an inclined material distribution frame, a material distribution drive cylinder, a baffle frame, and a material distribution translation drive mechanism capable of driving the material distribution frame to translate along the arrangement direction of the material distribution bins. The material distribution frame has a hollow inclined flow channel inside. The material distribution drive cylinder is installed on the material distribution frame. The power output end of the material distribution drive cylinder is fixed to the baffle frame. By driving the baffle frame to move through the material distribution drive cylinder, the outlet of the inclined flow channel can be opened or closed.

[0008] Furthermore, the end of the inclined flow channel has a vertical baffle.

[0009] Furthermore, the baffle frame has three side plates, which together with the vertical baffle form a structure with a discharge port at the bottom.

[0010] Furthermore, the material distribution translation drive mechanism includes a material distribution servo motor, a synchronous pulley, and a synchronous belt. The synchronous belt is fitted onto the synchronous pulley, and the material distribution servo motor drives the synchronous pulley to rotate, thereby causing the synchronous belt to reciprocate and translate.

[0011] The material distribution rack is mounted on the synchronous belt via a fixing block.

[0012] Furthermore, the unloading device includes a support frame, a material-picking gripper, a material-picking lifting drive cylinder capable of driving the material-picking gripper to rise and fall, and a material-picking translation drive module capable of driving the material-picking gripper to translate.

[0013] The material handling jaws are moved from the tooling on the turntable to directly above the inlet of the inclined flow channel by the material handling translation drive module and the material handling lifting drive cylinder.

[0014] Furthermore, an upper sheet metal shell and a lower sheet metal frame are fixedly installed on one side of the machine. The lower sheet metal frame has multiple independent receiving slots, and the upper part of the receiving slots has an opening. The material distribution bin is located in the receiving slot and can be pulled out. The upper sheet metal shell is located directly above the lower sheet metal frame, and the upper sheet metal shell has multiple strip-shaped through holes that can be aligned with the corresponding openings.

[0015] Furthermore, the visual inspection device includes a mounting frame and a visual inspection camera, the visual inspection camera being mounted on the mounting frame and its position on the mounting frame being adjustable via an adjustment mechanism.

[0016] Furthermore, the visual inspection camera is located above, below, and to the side of the turntable.

[0017] Furthermore, the outer cover of the testing machine is a housing.

[0018] The beneficial effects of this utility model are:

[0030] Tooling 10. Detailed Implementation

[0031] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0032] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0033] Example: A novel appearance inspection machine, such as Figures 1 to 7 As shown, it includes a machine base 1 and a turntable 2 on the machine base, multiple visual inspection devices 3 for detecting product appearance defects, a feeding device 4, a discharging device 5, a distributing device 6, and a row of distributing bins 7. The turntable is provided with multiple tooling fixtures 10 for placing products, and multiple visual inspection devices are arranged at intervals around the turntable.

[0034] One row of the material distribution bins is located on one side of the machine.

[0035] The material distribution device 6 includes an inclined material distribution frame 61, a material distribution drive cylinder 62, a baffle frame 63, and a material distribution translation drive mechanism 64 that can drive the material distribution frame to translate along the arrangement direction of the material distribution bin. The material distribution frame has a hollow inclined flow channel inside. The material distribution drive cylinder is installed on the material distribution frame. The power output end of the material distribution drive cylinder is fixed to the baffle frame. The opening or closing of the outlet of the inclined flow channel can be realized by driving the baffle frame to move through the material distribution drive cylinder.

[0036] In this embodiment, the end of the inclined flow channel has a vertical baffle 611.

[0037] In this embodiment, the baffle frame has three side plates 631, which together with the vertical baffle form a structure with a discharge port at the bottom. Firstly, this structure of the baffle allows the outlet of the inclined flow channel to open or close under the action of the material distribution drive cylinder. Secondly, when the product enters the corresponding material distribution bin, the three side plates and the vertical baffle act as a guide and buffer, preventing the product from splashing too far and being damaged by impacts.

[0038] In this embodiment, as Figure 5 As shown, the material distribution translation drive mechanism 64 includes a material distribution servo motor 641, a synchronous pulley 642 and a synchronous belt 643. The synchronous belt is fitted onto the synchronous pulley, and the material distribution servo motor drives the synchronous pulley to rotate, thereby driving the synchronous belt to reciprocate and translate.

[0039] The material distribution frame is mounted on the synchronous belt via a fixing block 644. In this embodiment, the fixing block has serrations to increase its stability after mounting on the synchronous belt. The fixing block is slidably connected to the machine tool via a linear guide rail to ensure the stability of the material distribution frame during translation.

[0040] In this embodiment, as Figure 7 As shown, the unloading device 5 includes a support frame 51, a material-picking gripper 52, a material-picking lifting drive cylinder 53 capable of driving the material-picking gripper to rise and fall, and a material-picking translation drive module 54 capable of driving the material-picking gripper to translate.

[0041] The material handling jaws are moved from the tooling on the turntable to directly above the inlet of the inclined flow channel by the material handling translation drive module and the material handling lifting drive cylinder.

[0042] In this embodiment, the structure of the feeding device is similar to that of the unloading device, so it will not be described in detail. The difference is that the function of the feeding device is to place the product to be tested onto the tooling of the turntable.

[0043] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, an upper sheet metal shell 11 and a lower sheet metal frame 12 are fixedly installed on one side of the machine. The lower sheet metal frame has multiple independent receiving slots 121, each with an opening at the top. The dispensing bin is located within the receiving slot and can be pulled out. The upper sheet metal shell is located directly above the lower sheet metal frame and has multiple strip-shaped through holes 111 that can be aligned with the corresponding openings. These through holes facilitate observation of the product in each powder bin.

[0044] In this embodiment, as Figure 3 As shown, the visual inspection device 3 includes a mounting frame 31 and a visual inspection camera 32. The visual inspection camera is mounted on the mounting frame, and its position on the mounting frame can be adjusted by an adjustment mechanism 33. The adjustment mechanism is existing technology and will not be described in detail; it is sufficient that the position of the visual inspection camera on the mounting frame can be adjusted.

[0045] In this embodiment, the visual inspection cameras are located above, below, and to the side of the turntable. They are used for omnidirectional inspection of the product's appearance, and the position and number of the visual inspection cameras can be set as needed.

[0046] In this embodiment, as Figure 1 As shown, the outer cover of the testing machine is a housing 8.

[0047] The turntable is a rotating disc, and the mechanism that enables the turntable to rotate is existing technology, so it will not be described in detail.

[0048] The working principle and process of this utility model:

[0049] The feeding device places the product to be inspected onto the fixture on the turntable. The turntable rotates the fixture and the product. Multiple vision inspection cameras inspect the product's appearance, and the inspection data is stored in the inspection machine's control system. When the product rotates to the unloading station, the unloading device removes the inspected product from the fixture and moves it directly above the inlet of the inclined flow channel. The unloading device's gripper releases, and the product falls into the inlet of the inclined flow channel and slides down to the outlet. During this process, the distribution drive cylinder drives the baffle frame to block the outlet of the inclined flow channel, ensuring the product remains within the channel and does not fall. The control system, based on the product's appearance inspection results, controls the distribution translation drive mechanism to move the distribution rack directly above the corresponding distribution bin. Then, the distribution drive cylinder drives the baffle frame to release the outlet of the inclined flow channel, and the product falls into the corresponding distribution bin.

[0050] Compared to the purging-based material distribution method, the material distribution device of this invention has a higher manufacturing cost, but a wider range of applications, better material distribution effect, and no material leakage.

[0051] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
