[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0037] like Figure 1 and Figure 2 As shown, the utility model proposes a multi-angle detection automatic sorting device 100 for crimping terminals, comprising a transport mechanism 1, a multi-angle detection device 2, and a sorting mechanism 3. The transport mechanism 1 comprises a transport portion 11 extending along a first direction for transporting crimping terminals; the multi-angle detection device 2 comprises a plurality of visual detectors arranged at intervals along the first direction on the transport portion 11, the plurality of visual detectors comprising a first visual detector 21 and a second visual detector 22 arranged at radially different positions in the first direction, the first visual detector 21 being used to detect the front of the crimping terminal, and the second visual detector 22 being used to detect the back of the crimping terminal; the sorting mechanism 3 comprises a plurality of pushing portions 31 arranged corresponding to the plurality of visual detectors, the plurality of pushing portions 31 being used to push the crimping terminal away from the transport portion 11 along the second direction.

[0038] The technical solution of the utility model uses the transport mechanism 1 to transport the crimping terminal in the first direction, uses the first visual detector 21 to photograph the front image of the crimping terminal, and uses the second visual detector 22 to photograph the back image of the crimping terminal, and unqualified crimping terminal products are separated from the transport part 11 in the second direction under the action of the pushing part 31, so that the final qualified products are transported to the end of the transport part 11. The crimping terminal is inspected from multiple angles to improve the quality of the crimping terminal products.

[0039] It can be understood that the pushing part 31 can adopt a cylinder, and the gas blown out by the cylinder can push the crimping terminal to separate it from the transportation part 11, which is suitable for crimping terminals with lighter weight; the pushing part 31 can also adopt a hydraulic or pneumatic driven piston telescopic rod, which directly contacts the crimping terminal and pushes it to the transportation part 11, which is suitable for crimping terminals with heavier weight. Of course, the specific selection can be set according to the actual industrial needs of technical personnel in this field, and no limitation is made here.

[0040] It can be understood that multiple visual detectors and multiple push parts 31 are all connected to the motor of the circuit control board. Under the control of the current control board, they can automatically execute preset program steps, receive image signals generated by multiple visual detectors, and after analysis, control the corresponding push parts 31 to work, thereby realizing an automatic sorting process and reducing manual intervention.

[0041] In one embodiment, the transport mechanism 1 includes a first transport belt 111 and a second transport belt 112 arranged along a first direction, the transport unit 11 is installed above the first transport belt 111 or the second transport belt 112, and the second visual detector 22 is installed below the junction of the first transport belt 111 and the second transport belt 112.

[0042] It is understandable that since the conveyor belt is usually supported by an opaque material and the visual detector is difficult to install inside the conveyor belt, the second visual detector 22 is installed below the junction of the first conveyor belt 111 and the second conveyor belt 112 in this application. When the wire crimping terminal transitions from the first conveyor belt 111 to the second conveyor belt 112, it will pass through the detection range of the second visual detector 22. The back of the wire crimping terminal can be effectively detected without being affected by the conveyor belt itself. At the same time, the first conveyor belt 111 and the second conveyor belt 112 can be driven by a motor to drive the transmission roller to make the conveyor belt circulate in a circular motion. This is a conventional setting of those skilled in the art, and other drive structures can also be used, which is not particularly limited here.

[0043] In one embodiment, a transverse spacing 113 is formed at the junction between the first conveyor belt 111 and the second conveyor belt 112, and the length of the transverse spacing 113 is less than half the length of the wire crimping terminal. The detection position of the second visual detector 22 photographs the back side of the wire crimping terminal passing through the transverse spacing 113.

[0044] It is understandable that in order to prevent the crimping terminal from shaking when passing through the transverse spacing 113, affecting the accuracy of the detection, or even falling and causing the detection to be terminated. Therefore, in this embodiment, by making the distance of the transverse spacing 113 less than half the length of the crimping terminal, when one end of the crimping terminal leaves the first conveyor belt 111 and is about to enter the second conveyor belt 112, the center of gravity of the crimping terminal is still on the first conveyor belt 111, maintaining the stability of the crimping terminal when passing through the transverse spacing 113, and at the same time giving the second visual detector 22 enough camera time for detection.

[0045] In addition, it should be noted that, in order to accommodate crimping terminals of different specifications, the first conveyor belt 111 and the second conveyor belt 112 can be movably arranged relative to each other, so as to adjust the length of the cross-sectional distance 113 formed therebetween.

[0046] In one embodiment, the transport mechanism 1 also includes a transparent plate 114, which is arranged at the intersection between the first transport belt 111 and the second transport belt 112. The length of the transparent plate 114 is less than the length of the wire crimping terminal, and the detection position of the second visual detector 22 photographs the back side of the wire crimping terminal passing through the transparent plate 114.

[0047] It can be understood that the transparent plate 114 makes the wire crimping terminal more stable when passing through the cross-sectional distance 113, and the transparent plate 114 will not block the camera of the second visual detector 22, and the length of the transparent plate 114 is smaller than the length of the wire crimping terminal, ensuring that one end of the wire crimping terminal enters the second conveyor belt 112 after leaving the first conveyor belt 111, and the other end is still on the first conveyor belt 111, ensuring the stability of the drive of the wire crimping terminal, and avoiding multiple wire crimping terminals from staying on the transparent plate 114 due to loss of kinetic energy, causing detection interruption.

[0048] In addition, the material of the transparent plate 114 can have high transparency and wear resistance, and polycarbonate (PC) can be selected. Polycarbonate is a high-strength, high-transparency engineering plastic with excellent impact resistance and wear resistance. It can withstand the pressure of heavier objects and can still maintain good optical properties after long-term use; Acrylic (PMMA) - Acrylic, also known as organic glass, is a plastic with extremely high transparency, and its transparency is close to that of glass, but it is lighter and not easy to break; Polymethyl methacrylate (PMMA) - PMMA is a type of acrylic acid, which is very widely used in industrial applications. It not only has high transparency, but also has good weather resistance and chemical stability; Glass - Glass has extremely high transparency and hardness, and glass is still a reliable choice. Specially treated tempered glass or chemically strengthened glass can increase its durability; Polyethylene Terephthalate (PET) - PET transparent sheet is also commonly used as the transparent plate 114, which has good transparency, chemical resistance and wear resistance, and has a relatively low cost. In practical applications, selection can be made based on specific usage requirements and expected lifespan.

[0049] like Figure 2 As shown, in one embodiment, the transparent plate 114 is retracted toward the middle thereof on both sides in the second direction, and baffles are provided on the sides thereof.

[0050] It is understandable that the transparent plate 114 is contracted toward the middle on both sides of the second direction, and the formed baffle can limit the movement path of the crimping terminal conveyed via the first conveyor belt 111, making its position more concentrated, which is conducive to the placement and detection of the second visual detector 22, making it more concentrated on the back of the crimping terminal, and improving the accuracy and efficiency of the detection. At the same time, compared with the straight transparent plate 114, the amount of material used can be reduced, the production cost can be reduced, and the overall weight of the equipment may also be reduced.

[0051] like Figure 3 As shown, in one embodiment, the multi-angle detection device 2 further includes a ring light 25, which is mounted on multiple visual detectors.

[0052] It can be understood that the design of the ring light 25 can ensure that the intensity of light radiating outward from the center point is uniform, reducing shadows and reflections, and the uniform illumination can enhance the contrast between the surface features of the object and the background, allowing the visual detector to more accurately identify minor defects or changes.

[0053] When the ring light 25 is set around multiple visual detectors, it can ensure that the crimping terminals can obtain consistent lighting conditions no matter from which angle the inspection is performed. Since the crimping terminals are made of metal and can reflect light and cause glare, the light of the ring light 25 comes from all directions rather than a single direction. The ring light 25 can reduce the glare on the surface of the inspected object and improve the clarity of the image and the visibility of details.

[0054] In addition, the brightness of the ring light 25 can be set to adjustable brightness, and the light intensity can be adjusted according to different detection requirements to adapt to the detection of crimping terminals of different materials or colors.

[0055] In one embodiment, the multiple visual detectors also include a third visual detector 23 and a fourth visual detector 24 arranged at radially different positions in the first direction, the third visual detector 23 is used to detect one side of the crimping terminal, and the fourth visual detector 24 is used to detect the other side of the crimping terminal.

[0056] It can be understood that by using the third visual detector 23 to detect one side of the crimping terminal and the fourth visual detector 24 to detect the other side of the crimping terminal, the four sides of the crimping terminal can be detected, which greatly improves the control of the quality of the crimping terminal and improves the accuracy of detection.

[0057] In one embodiment, the multi-angle detection device 2 further includes a light shielding box 26 installed on the transport portion 11 , and a plurality of visual detectors are located in the light shielding box 26 .

[0058] It is understandable that the light shielding box 26 can block external light, especially natural light and ambient light in the workshop. These lights may cause unexpected reflections or shadows in the image, affecting the visual detector's accurate photography of the crimping terminal image. In a closed environment with strict light control, the visual detector can more effectively identify the details of the crimping terminal and reduce the false detection rate caused by environmental factors. The built-in ring light 25 can ensure that each detection has the same and controllable light intensity and direction, thereby improving the consistency of the detection results. At the same time, it can also protect the multiple internal visual detectors, prevent dust, oil and other pollutants from damaging the lens, and extend the service life of the equipment.

[0059] like Figure 4 As shown, in one embodiment, the sorting mechanism 3 further includes a plurality of storage boxes 32 , which are arranged one by one corresponding to the pushing parts 31 , and are used to store the crimping terminals dropped from the transport part 11 .

[0060] It is understandable that each storage box 32 receives the crimping terminals from a specific push unit 31, which means that the crimping terminals that are unqualified or meet specific standards will be collected in different storage boxes 32 respectively. This classified storage helps to simplify subsequent processing steps, such as rework, repair or scrapping. The need for manual intervention is reduced, and there is no need to manually screen and place the crimping terminals, which improves the efficiency and accuracy of the sorting process. The storage box 32 can also be connected to a data management system to record the specific information of the crimping terminals in each storage box 32, such as test results, quantity and timestamp, to facilitate quality traceability and data analysis.

[0061] In one embodiment, the sorting mechanism 3 further includes a plurality of weighing sensors 33 , which are arranged at the bottom of the storage boxes 32 in a one-to-one correspondence with the storage boxes 32 , and are used to detect the weight of the crimping terminals in each storage box 32 .

[0062] It is understood that the weighing sensor 33 can verify whether the crimping terminal meets the predetermined weight standard. If the detected weight exceeds the allowable tolerance range, this may indicate that there is a manufacturing defect in the crimping terminal, such as insufficient or excessive material, or foreign matter mixed in. At the same time, when the weight of the storage box 32 is close to full load, the weighing sensor 33 can trigger an early warning signal to remind the operator to replace or empty the storage box 32 in time to avoid overflow or production line blockage.

[0063] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
