Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of meteorological sensor detection, and particularly relates to an automatic detection and analysis device and system for terminal cross-sections. Background Art
[0002] A weather station can monitor meteorological data and environmental data in real time, so a variety of meteorological sensors are often used, such as temperature sensors, humidity sensors, wind speed and direction sensors, barometric pressure sensors, etc. During the production of these meteorological sensors, safety quality detection and analysis are carried out on the internal wire harness terminals to improve the detection accuracy and service life when the meteorological sensors are used. Problems encountered during the wire harness terminal crimping process include defects such as cutting chips jumping out, fan surface defects, and uneven spacing. Therefore, the detection and analysis of the terminal cross-section have become a key microscopic detection means for confirming the crimping quality. The terminal cross-section detector based on meteorological sensors is a professional device mainly used for detailed detection and analysis of the terminal cross-section. It has a high-precision image acquisition system that can capture the fine structure of the terminal cross-section.
[0003] Existing terminal cross-section detectors have many technical defects when in use. First, the current terminal cross-section detectors can only detect one wire harness terminal at a time. Given that each group of wire harness terminals needs to go through multiple steps such as cutting, grinding, and corrosion during detection, the detection efficiency of the terminals is low and the time consumption is long. Second, the current grinding and corrosion steps are processed by two independent mechanisms respectively, resulting in a complex structure, lack of simplicity, and large volume in the design of existing terminal cross-section detectors. Third, when using the detection light source to irradiate the detection cross-section of the terminal, it is easy for the image displayed to have bright and dark interfaces due to external light refraction and interference, affecting the imaging quality.
[0004] In summary, considering that the existing facilities cannot meet the working requirements, for this reason, we propose an automatic detection and analysis device and system for terminal cross-sections. Summary of the Invention

Cooperate with starting the servo control motor to drive the sprocket on one of the axles to rotate, and through the rotary motion of the rotary chain plate, the entire chain plate structure works counterclockwise, pulling the terminal transfer tooling to complete all tasks at one time, replacing the traditional lead screw or cylinder traction structure, reducing the ineffective movement path, and improving the automation degree of detection.
[0031] Start the first cylinder, causing the first telescopic rod to extend outward, pushing the displacement seat to move linearly, the pushing block and the inclined sliding surface to slide relative to each other, causing the pushing block and the pressure rod to move radially, and the pressure rod drives the pressing piece to act on the terminal wire in the corresponding clamping sleeve, fully pressing and fixing it. Several groups of pressing pieces act on the terminal wires of each clamping sleeve simultaneously, completing the positioning task of multiple groups of terminals at one time, saving time and effort.
[0032] Start the second cylinder, retract the second telescopic rod, causing the sliding plate to perform a limiting linear motion. The four groups of driving teeth act on the five groups of meshing grooves of the driving wheel in turn, causing the driving wheel to flip 180°, so that the driving wheel flips from one set of locking planes to another set of locking planes, forming a stable self-locking state, improving the stability of the double-sided flipping plate. Cause the short shaft to move around the positioning bearing, making the double-sided flipping plate in the middle position flip 180° counterclockwise, automatically switch between the grinding mode and the corrosion mode, and integrate the grinding mechanism and the corrosion coating structure, thereby reducing the complexity of the device, reducing the volume, and making the device more scientific and efficient.
[0033] With the power of the second cylinder, during the flipping process of the double-sided flipping plate, the positions of the two curved liquid storage grooves in the liquid dipping tank are swapped up and down. During the swapping process, the corrosive liquid in the liquid storage groove will flow downward and pass through the position of the sponge core. The sponge core adsorbs part of the corrosive liquid to ensure that the compressed sponge body is fully wetted, achieving the effect of automatic and timely feeding. Description of the Drawings

The grinding disc 58 is fixed and is a passive grinding type without driving. The grinding disc 58 acts on the cross-section of the terminal 92 (by adjusting the horizontal position of the double-sided turning plate 57, the grinding degree of the terminal 92 can be adjusted). An arc connecting portion 59 is arranged around the grinding disc 58, which plays a role in smooth transition to prevent the terminal 92 from being stuck during the self-movement process, as Figure 9-11 shown.

A limit card slot 61 is opened inside the arc movement groove 60. A compression sponge body 62 that acts on the cross-section of the terminal 92 is arranged in each limit card slot 61. The limit card slot 61 plays a role in receiving and limiting. The compression sponge body 62 has a certain telescopic performance, as Figure 9-11 shown.
[0073] Specifically, the root of the compressed sponge body 62 extends to the inside of the double-sided flip plate 57 and is connected to a sponge core 64. The sponge core 64 has the function of automatically penetrating and guiding liquid. The sponge core 64 is located in the middle of the liquid immersion groove 63 (it cannot be exposed to the corrosive liquid under normal conditions).

The outside of the liquid immersion groove 63 is connected to a liquid adding sealing tube 66. The liquid adding sealing tube 66 extends out of the double-sided flip plate 57. When the tube cover is opened, the corrosive liquid can be injected into the curved liquid storage groove 65. Figure 9-11 shown.
[0074] Furthermore, two sets of card slots 90 are symmetrically opened at the edge of the end surface of the substrate 1. The card slots 90 are used to install the external protective cover, which plays a role in dust and touch prevention. Figure 1 shown.
[0075] When the present embodiment is in use, the terminal wiring 91 of several groups of terminals 92 are first sequentially placed into several groups of clamping sleeves 28 of the terminal transfer tooling 20 (the outer ends of the terminals 92 and the clamping sleeves 28 are in contact with each other), and then the first cylinder 30 is started, causing the first telescopic rod 31 to extend outward, pushing the displacement seat 32 to move linearly in the linear limit groove, causing the clamping structure 35 in each group of slide grooves 33 to move relative to each other, and the pushing block 351 and the inclined sliding surface 34 to slide relative to each other, causing the pushing block 351 and the pressure rod 353 to move radially (the reset spring 354 is compressed to generate elastic force), and the pressure rod 353 drives the pressing piece 355 to act on the terminal wiring 91 in the corresponding clamping sleeve 28, fully pressing and fixing it, and several groups of pressing pieces 355 act on the terminal wiring 91 of each clamping sleeve 28 at the same time, respectively, to complete the terminal positioning at one time.
[0076] Then the servo control motor 16 is started to drive the sprocket 11 on one set of the wheel axles 10 to rotate, and the rotating motion of the rotating chain plate 12 makes the entire chain plate structure work counterclockwise, pulling the terminal transfer tooling 20 to move from bottom to top to the position of the cutting wheel 42 that is rotating at high speed, and the terminals 92 in a set of clamping sleeves 28 near the top of the rotating column 23 slowly contact the cutting wheel 42 during the linear motion until they are completely cut off to form a detection section, and then the servo motor 27 is started to drive the small gear 26 to rotate, causing the large gear 25 to rotate through meshing deceleration, driving the rotating column 23 to make a circular motion around the connecting seat 21, so that the terminals 92 in other clamping sleeves 28 contact the cutting wheel 42 in turn during the circular motion (each group of terminals 92 will pass through the cutting area of the cutting wheel 42 on the path of the circular motion), and the cutting is completed in turn.
[0077] At this time, the rotary chain plate 12 continues to drive the terminal transfer tooling 20 with the detection section to move linearly to the left until a set of clamping sleeves 28 on the top of the rotating column platform 23 are aligned with the grinding disc 58 area of the double-sided flipping plate 57. At this time, the hydraulic adjusting rod 54 in the hydraulic actuator 55 is retracted, causing the adjusting seat 52 to move along the guiding rail seat 50 (the two sets of T-shaped guiding blocks 53 move linearly along the limiting rails 51 respectively) until the grinding disc 58 contacts the detection section of the terminal 92. At this time, the rotating column platform 23 is again made to perform a circular motion around the connecting seat 21, causing the terminals 92 on each set of clamping sleeves 28 to perform a circular motion (a circular motion with a relatively high speed) for a period of time, and during the motion, they take turns to come into full contact and friction with the grinding disc 58 to polish and clean the detection section.
[0078] Then, the hydraulic adjusting rod 54 in the hydraulic actuator 55 is extended to drive the adjusting seat 52 to move outwards, causing the double-sided flipping plate 57 to move away from the terminal transfer tooling 20. At this time, the second cylinder 754 is started, and the second telescopic rod 755 is retracted, causing the sliding plate 751 to perform a limiting linear motion in the sliding limiting cavity. During the motion of the sliding plate 751, the four sets of driving teeth 74 act on the five sets of meshing grooves of the driving wheel 72 in turn (meshing in turn to generate a force), causing the driving wheel 72 to flip 180°, so that the driving wheel 72 flips from one set of locking planes 73 to the other set of locking planes 73, forming a stable self-locking state, causing the short shaft 70 to move around the positioning bearing 71, and causing the double-sided flipping plate 57 in the middle position to flip 180° counterclockwise, so that the side with the arc motion groove 60 is aligned with a set of clamping sleeves 28 on the top of the rotating column platform 23.
[0079] At this time, the hydraulic adjusting rod 54 in the hydraulic actuator 55 is again retracted until the terminal 92 in the clamping sleeve 28 extends into the arc motion groove 60. The rotating column platform 23 is again made to perform a circular motion around the connecting seat 21, causing the terminals 92 on each set of clamping sleeves 28 to perform a circular motion and take turns to enter the arc motion groove 60 and contact several sets of compressed sponges 62 in the arc motion groove 60 to squeeze them. Corrosion liquid is generated on the surface of the compressed sponges 62 after compression, and the corrosion liquid is fully contaminated onto the detection section of the terminal 92 to achieve the purpose of corrosion; during the flipping process of the double-sided flipping plate 57, the positions of the two curved liquid storage grooves 65 in the liquid dipping groove 63 are interchanged up and down. During the interchange process, the corrosion liquid in the liquid storage groove will flow downwards and pass through the sponge core 64, and the sponge core 64 adsorbs part of the corrosion liquid to ensure that the compressed sponges 62 are fully wetted.
[0080] Next, the rotary chain plate 12 continues to pull the terminal transfer tooling 20 with a detection cross-section downward, stops at the position of the detection light source 6, and then uses the high-definition imaging device 3 to image the terminals 92 in a group of clamping sleeves 28 on the top of the rotating column platform 23, which is transmitted to the computer monitor to form a high-definition picture, and then is detected and analyzed. The morphological algorithm is used to count the number and distribution of defects, and then the rotating column platform 23 makes a circular motion around the connecting seat 21, so that the terminals 92 on each group of clamping sleeves 28 take turns to move to this position for imaging, and the detection of the terminals 92 is completed batch by batch. Embodiment 2
[0081] On the basis of Embodiment 1, when the detection light source 6 irradiates the detection cross-section of the terminals 92, it is easy to cause a light and dark interface in the displayed image due to external light refraction and interference, which affects the imaging quality. To solve the above problems, we have the following design, as Figure 13-15 shown.
[0082] Specifically, two groups of rotating shafts 80 are symmetrically and rotatably arranged on the outer side surface of the detection light source 6. The rotating shafts 80 are fixed to the outer shell of the detection light source 6 through connecting bearings. At the end of each group of rotating shafts 80 away from the detection light source 6, a mounting bracket 81 is welded. The lower ends of the two mounting brackets 81 are connected with a light-shielding cover 82 acting on the terminals 92, as Figure 13 and 14 shown.
[0083] In this embodiment, an adjusting handle 83 is welded to the end of one of the mounting brackets 81. A strip-shaped rolling groove 84 is opened on the inner side surface of the adjusting handle 83. An adjusting hydraulic cylinder 85 is inclinedly arranged on the side surface of the light source seat 5. A hydraulic driving rod 87 extends downward and obliquely inside the adjusting hydraulic cylinder 85. A rolling wheel 88 is installed at the lower end of the hydraulic driving rod 87. The rolling wheel 88 is limited to extend into the strip-shaped rolling groove 84. The two ends of the strip-shaped rolling groove 84 are the initial and end points of the movement, as Figure 14 and 15 shown.
[0084] Furthermore, the upper end of the adjusting hydraulic cylinder 85 is connected to the side surface of the light source seat 5 through a mounting seat 86 (the connection method has two types: movable and fixed, and is designed according to the actual situation).
[0085] In the use of this embodiment, when a set of terminals 92 move to the top position of the rotating column platform 23, the adjusting hydraulic cylinder 85 is started, and the hydraulic driving rod 87 retracts upward, so that the rolling wheel 88 rolls along the strip-shaped rolling groove 84 and acts on the adjusting handle 83, pulling the two sets of rotating shafts 80 to rotate outside the detection light source 6, so that the light-shielding cover 82 originally located outside the terminal 92 rotates to directly below the detection light source 6, surrounding the entire terminal 92. With the illumination of the detection light source 6, a more uniform and concentrated illumination is formed on the detection section, improving the imaging quality. Then, the hydraulic driving rod 87 is extended downward, and through a series of transmissions, the light-shielding cover 82 rotates back and forth to the outside of the terminal 92 (in an inclined state), so as not to interfere with the circumferential movement of the terminal 92 at the upper end of the clamping sleeve 28.
