A plastic toy appearance inspection device

Abstract

This utility model discloses a plastic toy appearance inspection device, including a frame and a pressure sensor. The frame has an internal mounting bracket, and a first conveyor belt is mounted on the top of the mounting bracket. Two sets of adapter plates are symmetrically distributed at the bottom of the mounting bracket, with two adapter plates in each set. Each adapter plate has a connecting groove on its upper part. A touch control module is mounted on one side of the top of the frame. During inspection, the first conveyor belt can simultaneously transport multiple plastic toys. When a plastic toy passes under an industrial camera module, it is photographed, detected, and recorded. Since the plastic toys are placed onto the first conveyor belt one by one, the weight difference detected by the pressure sensor each time indicates the currently photographed and detected plastic toy, thus quickly completing the matching process, facilitating subsequent screening, and improving efficiency.

Description

Technical Field

[0001] This utility model specifically relates to the technical field of clean benches, and more specifically to a plastic toy appearance inspection device. Background Technology

[0002] Plastic toys are products made primarily of plastic, processed through injection molding, blow molding, extrusion, and other processes, intended for children's play, entertainment, or educational purposes. As a commodity, appearance inspection of plastic toys is essential. Inspection can detect burrs, flash, sharp edges, and loose small parts on the toy's surface, all of which could potentially cause children to scratch their skin or choke if swallowed. Therefore, appearance inspection equipment is frequently used in the production process of plastic toys.

[0003] Currently used appearance inspection equipment typically uses a conveyor belt and an industrial camera to analyze and inspect the appearance of products. Appearance inspection and weight inspection are usually performed separately. Therefore, appearance inspection data and weight data need to be rematched after inspection, which affects the efficiency of inspection and rejection. This has drawbacks in use. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic toy appearance inspection device to solve the problem mentioned in the background art that the appearance inspection and weight inspection of the currently used appearance inspection devices are usually carried out separately. Therefore, the appearance inspection data and weight data need to be rematched after the inspection is completed, which affects the efficiency of inspection and waste screening. Therefore, there are drawbacks in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A plastic toy appearance inspection device includes a frame and a pressure sensor. The frame has an internal mounting frame, and a first conveyor belt is installed on the top of the mounting frame. Two sets of adapter plates are symmetrically distributed at the bottom of the mounting frame, and two adapter plates are symmetrically distributed in each set. Each adapter plate has a connecting groove on its upper part. A touch module is installed on one side of the top of the frame. As a further embodiment of this utility model: the pressure sensor is installed inside the frame, and the top of the pressure sensor is fixedly connected to the bottom of the mounting bracket; four limiting plates are symmetrically distributed inside the frame, and each limiting plate is slidably connected to a connecting groove. As a further embodiment of this utility model: a linear module is installed on one side of the top of the frame, and an industrial camera module is installed on the top of the linear module; a discharge chute is installed at one end of the frame, and two distribution chutes are symmetrically distributed at the bottom of the discharge chute; a movable baffle is installed at the lower end of the interior of the discharge chute, and a motor is installed on one side of the outer wall of the discharge chute, and the motor is connected to the movable baffle for transmission; a second conveyor belt is provided below each distribution chute.

[0006] As a further embodiment of this utility model: the top of the mounting frame is symmetrically equipped with two sets of guide plates, and each set of guide plates has two plates symmetrically distributed. At the same time, the distance between the two guide plates in the same set decreases from the end away from the discharge chute to the other end.

[0007] As a further embodiment of this utility model: the linear module and the industrial camera module form a sliding structure, and the industrial camera module is located between two sets of guide plates.

[0008] As a further embodiment of this utility model: the connection between the discharge trough and the movable baffle is a rotatable connection, and the length of the movable baffle is greater than the width of the discharge trough.

[0009] As a further embodiment of this utility model: the two material distribution troughs are not connected to each other, and both material distribution troughs are connected to the discharge trough.

[0010] As a further embodiment of this utility model: the two second conveyor belts are symmetrically distributed, and the conveying directions of the two second conveyor belts are opposite.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention includes a mounting frame, a first conveyor belt, and a pressure sensor. The first conveyor belt and the pressure sensor are integrated into a single frame, improving integration. During detection, the first conveyor belt can simultaneously carry multiple plastic toys. When a plastic toy passes under the industrial camera module, it is photographed, detected, and recorded. Since the plastic toys are placed onto the first conveyor belt one by one, the weight difference detected by the pressure sensor each time indicates the currently photographed and detected plastic toy, thus quickly completing the matching process and facilitating subsequent screening, thereby improving efficiency.

[0012] This utility model includes a discharge trough, a sorting trough, and a movable baffle. After the plastic toys have been inspected, they are fed into the discharge trough via a first conveyor belt. The discharge trough is inclined downwards, and the plastic toys will automatically slide down under the influence of gravity after entering. The movable baffle, controlled by a motor, is linked to a touch control module. By controlling the rotation of the movable baffle, the connection between the discharge trough and the two sorting troughs can be quickly switched, which facilitates the rapid guidance of qualified and unqualified plastic toys into the two sorting troughs, thereby improving sorting efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 In this embodiment of the present invention, a plastic toy appearance inspection device includes a frame 1 and a pressure sensor 16. The frame 1 has an internal mounting bracket 2, and a first conveyor belt 3 is mounted on the top of the mounting bracket 2. Two sets of adapter plates 4 are symmetrically distributed at the bottom of the mounting bracket 2, with two adapter plates 4 in each set, and each adapter plate 4 has a connecting groove 5 on its upper part. A touch module 15 is mounted on one side of the top of the frame 1. The pressure sensor 16 is installed inside the frame 1, and its top is fixedly connected to the bottom of the mounting bracket 2. The machine frame 1 has four symmetrically arranged limiting plates 6 installed inside, and each limiting plate 6 is slidably connected to a connecting groove 5; a linear module 8 is installed on one side of the top of the frame 1, and an industrial camera module 9 is installed on the top of the linear module 8; a discharge chute 10 is installed at one end of the frame 1, and two distributing chute 11 are symmetrically connected to the bottom of the discharge chute 10; a movable baffle 12 is installed at the lower end of the discharge chute 10, and a motor 13 is installed on one side of the outer wall of the discharge chute 10, and the motor 13 is connected to the movable baffle 12 in a transmission connection; a second conveyor belt 14 is provided below each distributing chute 11.

[0023] As a further explanation of this embodiment, the connecting groove 5 is a waist hole structure. After the connecting groove 5 is connected to the limiting plate 6, it can effectively prevent the mounting frame 2 from lateral displacement and will not affect the weighing function of the mounting frame 2.

[0024] In this embodiment, two sets of guide plates 7 are symmetrically distributed on the top of the mounting frame 2, and two guide plates 7 are symmetrically distributed in each set. At the same time, the distance between the two guide plates 7 in the same set decreases from the end away from the discharge chute 10 to the other end.

[0025] More specifically, the bottom of the guide plate 7 maintains a certain gap with the surface of the first conveyor belt 3.

[0026] As a further explanation of this embodiment, two sets of guide plates 7 guide the direction of the passing plastic toy, ensuring that the plastic toy can accurately pass through the effective shooting area below the industrial camera module 9.

[0027] In this embodiment, the linear module 8 and the industrial camera module 9 form a sliding structure, and the industrial camera module 9 is located between the two sets of guide plates 7.

[0028] More specifically, the industrial camera module 9 is used to photograph and inspect the plastic toys passing below.

[0029] As a further illustration of this embodiment, the position of the industrial camera module 9 can be easily adjusted via the linear module 8.

[0030] In this embodiment, the discharge trough 10 and the movable baffle 12 are connected by a rotatable connection, and the length of the movable baffle 12 is greater than the width of the discharge trough 10.

[0031] More specifically, the rotating movable baffle 12 is controlled by motor 13.

[0032] As a further explanation of this embodiment, the connection state between the discharge chute 10 and the two distribution chute 11 can be adjusted by rotating the movable baffle 12.

[0033] In this embodiment, the two material distribution troughs 11 are not connected to each other, and both material distribution troughs 11 are connected to the discharge trough 10.

[0034] More specifically, the inner wall width of the material distribution trough 11 is half the inner wall width of the discharge trough 10.

[0035] As a further explanation of this embodiment, plastic toys are fed onto the corresponding second conveyor belts 14 through two material distribution troughs 11.

[0036] In this embodiment, the two second conveyor belts 14 are symmetrically distributed, and the conveying directions of the two second conveyor belts 14 are opposite.

[0037] More specifically, the effective width of the second conveyor belt 14 is greater than the width of the second conveyor belt 14.

[0038] As a further explanation of this embodiment, qualified and unqualified products are transported separately by two second conveyor belts 14.

[0039] The working principle of this utility model is as follows: When in use, first connect the external power supply and start the first conveyor belt 3. Place the plastic toys to be tested one by one on the first conveyor belt 3. The first conveyor belt 3 carries the plastic toys and moves them in a directional manner. Each time a plastic toy is placed on the first conveyor belt 3, the overall weight change of the mounting frame 2 is detected by the pressure sensor 16 and recorded by the touch module 15. When the plastic toy passes under the industrial camera module 9, the industrial camera module 9 is activated to take pictures of the passing plastic toy. The touch module 15 matches the appearance inspection results with the recorded weight change and judges whether the product is qualified. At the same time, it controls the motor 13 to rotate the movable baffle 12 and adjusts the discharge chute 10 to connect with the distribution chute 11 corresponding to the currently discharged product. After the plastic toy has been tested, it is fed into the discharge chute 10 through the first conveyor belt 3 and then transported to the corresponding second conveyor belt 14 through the corresponding connected distribution chute 11.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
