DETAILED DESCRIPTION

[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0047] Example 1:

[0048] This embodiment provides a terminal CCD vision inspection mechanism 1, including:

[0049] Mounting base 2, with mounting bracket 3 on mounting base 2;

[0050] The feeding base 4 is fixedly connected to the mounting bracket 3 and has a feeding channel 5 along the X direction;

[0051] Inspection window 6 is located on one side of the feeding channel 5;

[0052] The counting sensor 7 is located on one side of the opening of the feeding channel 5 and is used to count the number of terminals that pass through.

[0053] CCD camera 8 is mounted on mounting bracket 3;

[0054] The reflector 9 is used to reflect the image in the detection window 6 onto the CCD camera 8.

[0055] The upper surface of the mounting base 2 is provided with several mounting brackets 3 for mounting various structural components. The feeding base 4 is fixedly connected to one of the mounting brackets 3. A stop extending in the Z direction is formed on one side of the feeding base 4. The stop is used to limit one side of the terminal strip. The terminal strip structure includes a body and a continuous part. The continuous part is placed on top of the stop. Alternatively, the mounting base 2 is provided with a feeding channel 5 that allows the terminal strip to pass through. The feeding channel 5 and the outer contour of the terminal can have an equidistant gap of 0.1 mm, so that the terminal strip can pass stably in the feeding channel 5 without causing a large deviation. The detection window 6 is opened on one side of the channel and penetrates the feeding base 4. On the side wall, the counting sensor 7 is set on one side of the opening of the feeding channel 5. The counting sensor 7 is generally an infrared through-beam sensor. The two probes of the counting sensor 7 are set opposite each other, one is installed on the bottom surface of the feeding channel 5, and the other is installed on the other side of the terminal strip. The sensor counts the number of unqualified terminals, and the CCD camera detects the number of unqualified terminals. The number of qualified terminals can be known by the total number of terminals counted by the sensor and the number of unqualified terminals. For easy installation, a through opening can be opened on the bottom surface of the feeding channel 5 to allow infrared light to pass through. The two probes are installed on a C-shaped frame, and the C-shaped frame is fixedly installed to facilitate the positioning of the two through-beam probes.

[0056] The shooting direction of the CCD camera 8 can be the same as or opposite to the Z-axis, or it can be another direction. The position of the CCD camera 8 can be set to save space. The reflector 9 is set on the mounting bracket 3 and tilted at 45°. The two ends of the reflector 9 are the CCD camera 8 and the terminal strip in the detection window 6, respectively.

[0057] Working principle:

[0058] During the stamping and receiving process of terminals, it is necessary to conduct a quality inspection on the stamped terminal strip. Usually, a CCD camera 8 is used to take a picture of the side of the terminal strip with the probe. This usually requires a lot of space. By setting a reflector 9, the structure is bent, and the space is changed from horizontal to vertical, reducing the space occupied by the structure. The number of unqualified terminals is recorded by the CCD camera 8, and the total number of terminals is calculated by the counting sensor 7. The number of qualified terminals can be calculated and statistically analyzed.

[0059] Example 2:

[0060] This embodiment provides a terminal CCD vision inspection mechanism 1, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] At least one pressing belt mechanism 10 is provided on the feeding base 4, and the pressing belt mechanism 10 includes:

[0062] Mounting bracket 101;

[0063] Sliding seat 102 is slidably connected to mounting bracket 101 along the Z direction;

[0064] A contact wheel 103 is rotatably mounted on the sliding seat 102 and abuts against the surface of the terminal strip;

[0065] The reset elastic member 104 is used to drive the abutment wheel 103 on the sliding seat 102 to abut against the surface of the terminal strip.

[0066] At least one pressing belt mechanism 10 is provided on the feeding base 4. Usually, three are provided to increase stability. The pressing belt mechanism 10 includes a mounting frame 101, which is mounted on the mounting bracket 3. The mounting frame 101 is provided with two support rods extending in the Z direction. The top of the support rod is provided with a baffle. A sliding seat 102 is sleeved on the support rod. A reset elastic member 104 is also provided between the support rod and the baffle. The selected structure is a spring sleeved on the support rod. An insert rod is installed on the sliding seat 102 and inserted into the feeding base 4. An abutment wheel 103 is rotatably provided on the insert rod and abuts against the continuous part of the terminal strip. The continuous part is the part connecting the terminals.

[0067] It should be noted that a sliding connection between the sliding seat 102 and the mounting bracket 101 can be adopted, such as a slide rail structure.

[0068] Working principle:

[0069] The contact wheel 103 abuts against the surface of the terminal strip, which can make the position of the terminal strip more stable. Furthermore, by setting the reset elastic member 104, the contact wheel 103 has a certain position self-compensation, which can always keep the contact wheel 103 abutting against the continuous part of the terminal. In addition, the contact wheel 103 can rotate, which can effectively reduce the wear of the contact wheel 103.

[0070] Example 3:

[0071] This embodiment provides a terminal CCD vision inspection mechanism 1, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] Also includes:

[0073] The limiting part 11 is slidably disposed on the feeding base 4 along the Y direction, and the limiting part 11 and the feeding base 4 form a feeding channel 5;

[0074] The telescopic adjustment part 12 is mounted on the mounting bracket 3 and is used to drive the limiting part 11 to move.

[0075] The limiting part 11 is slidably disposed on the feeding base 4 along the Y direction. The feeding base 4 has a through hole that runs vertically through it. The bottom of the limiting part 11 has a sliding insert for insertion. The sliding insert can slide along the Y direction within the through hole. The lower end of the sliding insert is connected to the mounting platform through a guide rail structure, making the sliding of the limiting part 11 more stable. The position of the limiting part 11 can be adjusted by adjusting the telescopic part 12, thereby adjusting the width of the feeding channel 5 so that terminals of different sizes can pass through.

[0076] Furthermore, an adjustable abutment block is provided on the limiting part 11, which is used to limit the probe at different positions.

[0077] Example 4:

[0078] This embodiment provides a terminal CCD vision inspection mechanism 1, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] It also includes a light source module, which includes:

[0080] The light-emitting element 13 is disposed on one side of the terminal strip, on the opposite side of the reflector 9, and opposite to the detection window 6.

[0081] The light source module includes a power supply and a light emitter 13. The power supply can be a battery or an external power source. The light emitter 13 includes a lamp body and a light-emitting cover. The function of the light-emitting cover is to make the light more uniform and to serve as the background of the detection window 6. When the CCD camera 8 photographs the terminal, using the light emitter 13 as a background can make the outline of the terminal clearer and effectively improve the detection accuracy.

[0082] A transparent protective layer 14 is superimposed on the reflector 9.

[0083] The transparent protective layer 14 can be made of acrylic or glass. The transparent protective layer 14 can effectively protect the reflector 9 and make it easier to clean dust, thus avoiding affecting the clarity of the reflector 9.
