Description

Technical Field

[0001] The present invention relates to the technical field of detection, and specifically to a hole-type terminal detection device and a detection method. Background Art

[0002] In electrotechnics, a terminal mostly refers to a wiring terminal, also called a connection terminal. There are various types of terminals, and their main functions are to transmit electrical signals or conduct electricity. Terminals play an important role in electrical connections, and the quality of their performance directly affects the connection stability and service life of wires. Therefore, before the terminals are put into use, the staff needs to conduct a complete inspection on the terminals to ensure their quality.

[0003] In addition to having a small size error, a qualified terminal also needs to have sufficient toughness. A terminal with good toughness can better cope with various stresses and reduce the risk of fracture, thus ensuring the stable connection of wires. Currently, the detection of the toughness of terminals is carried out by means of bending. If the terminal can smoothly rebound to its original state within a certain degree of bending, it is a qualified product.

[0004] The existing toughness detections are all carried out using impact testing equipment. The corresponding equipment requires the staff to continuously replace the test objects beside it. The repetitive labor is not only boring but also greatly affects the detection efficiency. At the same time, a terminal needs to go through two processes of comprehensive size testing and toughness testing respectively, which will cause more time waste and is not conducive to the improvement of production efficiency. In view of this, the present invention proposes a hole-type terminal detection device and method. Summary of the Invention

[0079] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0080] Please refer to Figures 1-4 , the present application provides the following technical solutions:

[0081] A pin terminal detection device for detecting Figure 1The hole-type terminal 100 shown in the figure comprises a base 1, which comprises a shell 11 which is approximately a right-angled trapezoidal body as a whole, and a cavity inside the shell 11. The upper side and the horizontal side of the shell 11 are both provided with open openings. The open opening on the upper side of the shell 11 can be used to place or remove the hole-type terminal 100, and the open opening on the horizontal side is a discharge port for discharging unqualified hole-type terminals 100. A conveying mechanism 2 is provided in the cavity of the base 1, and the conveying mechanism 2 can convey the hole-type terminal 100 along a circular path. A plurality of carrying mechanisms 3 are provided on the conveying mechanism 2, and each carrying mechanism 3 can place a hole-type terminal 100. A first detection mechanism 4 and a second detection mechanism 5 are provided on the base 1. The first detection mechanism 4 comprises an image acquisition component 41, and the image acquisition component 41 can surround the hole-type terminal 100 to be detected for image acquisition. The second detection mechanism 5 is provided above the conveying path of the conveying mechanism 2, and can press down the hole-type terminal 100 in the carrying mechanism 3. The image acquisition component 41 can use a linear array camera to perform a full-scale scan and detection on the socket terminal 100. In this way, it can be determined whether the size of the socket terminal 100 meets the production standard. By moving the image acquisition component 41, it can scan from the side to the top of the socket terminal 100, so that the size and thickness of the socket terminal 100 can be fully detected, which is convenient for controlling the specific specifications of each socket terminal 100. With the help of the downward pressure of the second detection mechanism 5, the toughness of the socket terminal is tested.

[0082] On the basis of the above implementation scheme, a support assembly 12 is fixedly arranged in the cavity of the shell 11. The support assembly 12 is located at the lower side of the moving path of the carrier mechanism 3 and can support the carrier mechanism 3 during transportation. A discharge assembly 13 is arranged in the middle of the shell 11. The discharge assembly 13 is a slideway inclined toward the horizontal side of the shell 11. The discharge assembly 13 can receive unqualified hole-type terminals 100. The unqualified hole-type terminals 100 fall onto the discharge assembly 13 and then slide out of the shell 11. The support assembly 12 includes a horizontal plate, which is arranged below the parallel portion on the upper side of the conveyor belt 21. A drop opening is opened on the horizontal plate, and the upper end of the discharge assembly 13 is located below the drop opening; an arc plate is arranged on both sides of the horizontal plate, and the arc plate corresponds to the arc portion of the conveyor belt 21.

[0083] Based on the above implementation scheme, see Figure 4 and Figure 6, the conveying mechanism 2 includes a conveyor belt 21 that is integrally annular. The conveyor belt 21 includes two parallel upper and lower portions, and arc-shaped portions located at the ends of the two parallel portions. A circular groove 14 is provided on the inner wall of the housing 11 corresponding to the conveyor belt 21. The bearing mechanism 3 includes a bearing frame 31 in the shape of a rectangular frame. A connecting rod 311 is provided on the outer side of the frame of the bearing frame 31. The bearing frame 31 is connected to the conveyor belt 21 through the connecting rod 311, and the connecting rod 311 is slidably connected to the circular groove 14 on the inner wall of the housing 11. The conveyor belt 21 is linked with the driving assembly 22, and the driving assembly 22 drives the conveyor belt 21 to perform intermittent movement.

[0084] The hole-type terminals 100 are conveyed through the movement of the conveyor belt 21. When the conveyor belt 21 stops moving, the first detection mechanism 4 and the second detection mechanism 5 detect the hole-type terminals 100.

[0085] On the basis of the above implementation scheme, refer to Figure 6 , the bearing mechanism 3 further includes a clamping assembly 32. The clamping assembly 32 is arranged in the bearing frame 31 and can clamp the hole-type terminals 100. The clamping assembly 32 includes two clamping plates 321. Both clamping plates 321 are slidably connected to the bearing frame 31, and the two clamping plates 321 can approach or move away from each other; a profiling structure is provided on the clamping plates 321 corresponding to the hole-type terminals 100. A clamping plate connection assembly 322 is arranged between the two clamping plates 321. The clamping plate connection assembly 322 includes two clamping plate connecting rods 3221. The two clamping plate connecting rods 3221 correspond to the two clamping plates 321 respectively. One end of the clamping plate connecting rod 3221 is rotatably connected to a clamping plate 321, and the other end is rotatably connected to a clamping plate connection block 3222. The clamping plate connection block 3222 is arranged between the two clamping plates 321. A clamping plate guide 3223 is fixedly arranged on the upper side of the clamping plate connection block 3222. The clamping plate guide 3223 is a portal frame, and its lower end is fixedly connected to the clamping plate connection block 3222. A chute is provided on the outer side surface of the bearing frame 31. The clamping plate guide 3223 is slidably connected to the bearing frame 31 through this chute, and the sliding direction of the clamping plate guide 3223 is perpendicular to the sliding direction of the clamping plate 321. A clamping plate resetting member 3224 is arranged between the clamping plate connection block 3222 and the bearing frame 31. The clamping plate resetting member 3224 is a spring and can reset the clamping plate connection block 3222.

[0086] Refer to Figure 5, a clamping linkage structure 121 is provided on the support component 12 corresponding to the clamping component 32. The clamping linkage structure 121 is located on the upper horizontal side of the blanking port. The clamping linkage structure 121 is a convex platform extending upward, and both sides of the convex platform are arc-shaped transition surfaces. When the carrier frame 31 passes through the clamping linkage structure 121, the clamping linkage structure 121 can jack up the clamping plate connecting block 3222 upward. As the clamping plate connecting block 3222 moves upward, the two clamping plates 321 slide along the carrier frame 31, and the two clamping plates 321 move away from each other. As the clamping plates 321 move away from each other, the hole-type terminals 100 that do not meet the toughness standard fall onto the discharging component 13. The specific falling situation of the hole-type terminals 100 will be described in detail later. When the carrying mechanism 3 moves away from the clamping linkage structure 121, under the action of the clamping plate resetting member 3224, the clamping plate connecting block 3222 moves downward to reset, and the clamping plates 321 move closer to each other to maintain the clamping force on the hole-type terminals 100.

[0087] It should be noted that considering the image acquisition of the hole-type terminals 100 by the image acquisition component 41, the upper end surface of the plate body of the clamping plate 321 is located above the upper surface of the carrier frame 31 to ensure that the hole-type terminals 100 thereon will not cause the image acquisition component 41 to fail in image acquisition when it is on the horizontal side due to the frame structure of the carrier frame 31.

[0088] On the basis of the above implementation, the second detection mechanism 5 includes a second detection bracket 53. The second detection bracket 53 is fixedly arranged on the housing 11. A pressing rod 51 is arranged on the second detection bracket 53, above the conveying path of the conveying mechanism 2. The pressing rod 51 can move in the vertical direction; a pressing plate 52 is fixedly arranged at the lower end of the pressing rod 51; the hole-type terminals 100 in the carrying mechanism 3 are pressed by means of the pressing plate 52. A pressing position 122 is arranged on one side of the blanking port of the cross plate corresponding to the second detection mechanism 5, and a backing plate is arranged at the pressing position 122 corresponding to the pressing plate 52.

[0089] With this structure, at the blanking port position, the first detection mechanism 4 conducts the first detection on the hole-type terminals, mainly detecting the shape standards such as the size and thickness of the hole-type terminals. Then at the second detection mechanism 5, the hole-type terminals 100 on the pressing position 122 are pressed by means of the pressing plate 52, causing the hole-type terminals to deform to a certain extent. The hole-type terminals 100 that meet the toughness standard can return to their original shape, otherwise, they will show deformation depressions. When the carrying mechanism 3 rotates to the blanking port position again, under the action of the aforementioned clamping linkage structure 121, the distance between the clamping plates 321 increases. The non-deformed hole-type terminals still remain on the clamping plates 321, while the deformed hole-type terminals 100 fall due to the overall shortening of the length and are then discharged.

[0090] On the basis of the above embodiment, the inner side of the conveyor belt 21 of the conveying mechanism 2 is provided with continuous teeth. The driving assembly 22 includes a main driving wheel 221 arranged in the middle position inside the annular area of ​​the conveyor belt 21. The main driving wheel 221 is linked with the motor. The main driving wheel 221 is an incomplete gear, and its gear part is about one-third of the entire circumference. The main driving wheel 221 can mesh with the teeth on the inner side of the conveyor belt 21. A driven wheel 222 is respectively arranged at both ends of the annular structure of the conveyor belt 21. Through this structure, the intermittent motion of the conveyor belt 21 is realized.

[0091] On the basis of the above embodiment, a conveying linkage structure 223 is provided on the belt body of the conveying belt 21. The device also includes a detection linkage mechanism 6, and the conveying linkage structure 223 is linked with the detection linkage mechanism 6. When the conveying belt 21 stops moving, the detection linkage mechanism 6 can be linked with the first detection mechanism 4 and the second detection structure 5.

[0092] The conveying linkage structure 223 of this solution is a lever group arranged on one side of the conveyor belt 21, and the levers of the lever group are distributed along the conveyor belt 21. Figure 7 The detection linkage mechanism 6 includes a first linkage ring 61 and a second linkage ring 62, both of which are annular bodies and are rotatably connected to the housing 11. The inner side of the first linkage ring 61 is provided with inclined toggle grooves corresponding to the conveying linkage structure 223; when the conveyor belt 21 moves, the toggle rods of the conveying linkage structure 223 enter the toggle grooves one by one, thereby driving the first linkage ring 61 to rotate. The second linkage ring 62 is parallel and coaxially arranged with the first linkage ring 61; the first detection frame 41 is arranged between the first linkage ring 61 and the second linkage ring 62, and the first detection frame 41 is a crossbar structure, and its two ends are respectively fixedly connected to the first linkage ring 61 and the second linkage ring 62. The first image acquisition component 41 is arranged on the first detection frame 41.

[0093] In addition, see Figure 3, a linkage reset member 63 is arranged on one side of the second linkage ring 62, the linkage reset member 63 includes an arc rod, an arc spring is sleeved on the outer side of the arc rod, a push plate is arranged on the side of the second linkage ring 62 facing the arc rod, the push rod and the arc rod are slidably connected, and one end of the arc spring is against the push plate. When the second linkage ring 62 rotates under the drive of the conveyor belt 21, the arc spring is compressed. It should be noted that there is a spacing between the lever groups of the conveyor linkage structure 223, and the spacing is slightly larger than the width of the toggle groove. When the conveyor belt 21 stops, the spacing position of the lever group can just reach the position of the first linkage ring 61. At this time, because the conveyor belt 21 stops moving, the lever cannot enter the toggle groove. The linkage reset member 63 is reset, thereby driving the first linkage ring 61 and the second linkage ring 62 to rotate and reset in the opposite direction. The first linkage ring 61 and the second linkage ring 62 must also meet the requirement that they can be rotated to the horizontal side position of the first image acquisition component 41 facing the hole terminal 100 under the drive of the conveyor belt 21.

[0094] On the basis of the above implementation scheme, taking into account the commonality of the power structure, the pressure rod 51 of the second detection mechanism 5 is linked with the second linkage ring 62. When the second linkage ring 62 is reset, the pressure rod 51 can drive the pressure plate 52 to perform a downward pressing and resetting action.

[0095] This solution provides a specific linkage form, see Figure 8 and Figure 9 , the surface of the second linkage ring 62 is a bevel tooth surface, and a second linkage member 54 is arranged corresponding to the second linkage ring 62, and the second linkage member 54 is rotatably connected with the second detection bracket 53. And a bevel gear structure that can mesh with the second linkage ring 62 is arranged at the lower part of the second linkage member 54. A linkage block 55 is arranged on the inner wall of the second linkage member 54, and a spiral groove 56 is arranged on the rod body of the pressure rod 51. In addition, a limit rod 57 is arranged on the outer side of the rod body of the pressure rod 51, and the limit rod 57 is vertically slidably connected with the second detection bracket 53. The function of the limit rod 57 is to limit the pressure rod 51 to only vertical movement but not rotation. The second linkage member 54 satisfies that it can only rotate when the second linkage ring 62 is reset.

[0096] Through this structure, when the second linkage ring 62 is reset, the second linkage member 54 is driven to rotate, causing the driving block 55 to slide along the spiral groove 56, thereby driving the pressure rod 51 to perform a downward and upward movement.

[0097] Based on the above implementation scheme, for the one-way acting structure of the second linkage member 54, this solution proposes the following two implementation structures.

[0098] The first type is that the upper part of the second linkage 54 is a cylinder body, with a linkage block 55 arranged inside the cylinder body, and the lower part is connected to a bevel gear 58 through a one-way bearing. When the conveyor belt 21 indirectly drives the second linkage ring 62 to rotate, the one-way bearing allows the bevel gear 58 to rotate independently without driving the upper cylinder body of the second linkage 54 to rotate. When the second linkage ring 62 resets, it drives the bevel gear 58 to rotate. At this time, the one-way bearing allows the bevel gear 58 to drive the upper cylinder body to rotate synchronously.

[0099] The second type is as Figure 9 shown. The second linkage 54 is an integral cylinder structure with a linkage block 55 arranged inside. A bevel gear 58 is arranged at the lower part of the second linkage 54. One side edge of the tooth of the bevel gear 58 is rotationally connected to the circumferential side of the cylinder body, and a torsion spring is arranged at the connection. When the conveyor belt 21 indirectly drives the second linkage ring 62 to rotate, the second linkage ring 62 toggles the tooth to rotate, and the second linkage 54 does not rotate. When the second linkage ring 62 rotates in the reverse direction, the tooth cannot rotate, thereby causing the second linkage 54 to rotate.

[0100] Based on the above implementation schemes, corresponding to the aforementioned detection device, this scheme provides a detection method, including the steps:

[0101] S1. Place the hole-type terminal 100 to be detected on the clamping plate 31 in the loading mechanism 3;

[0102] S2. Use the conveyor belt 21 of the conveying mechanism 2 to intermittently convey the loading mechanism 3;

[0103] S3. When the conveyor belt 21 of the conveying mechanism 2 stops moving, there is a loading mechanism 3 corresponding to the first detection mechanism 4 and the second detection mechanism 5 respectively;

[0104] S4. The image acquisition component 41 of the first detection structure 4 moves around the hole-type terminal 100 in the corresponding loading mechanism 3 and performs image acquisition during the movement;
