Description

Technical Field

[0001] This invention relates to the field of electronic component testing equipment technology, and in particular to a smart connector testing device. Background Technology

[0002] Connectors mostly refer to electrical connectors, which connect two electronic subsystems through a separable interface to transmit current or signals. They are widely used in automotive electronics, communication networks, industrial equipment, and aerospace and defense.

[0003] Electrical connectors are indispensable basic components in modern electronic devices. Before production or use, connectors need to undergo performance testing to ensure they meet manufacturing or usage requirements. Traditional testing methods primarily involve manual inspection, where the connector is connected to an adapter and then to testing equipment. This is time-consuming, labor-intensive, and inefficient. With the development of automation technology, automated connector testing is becoming increasingly common. For example, a prior application with publication number CN117554866A discloses a connector testing device that automatically tests the connector after the manual insertion of the connector into the corresponding mating plug. While this improves testing efficiency to some extent, the main operational steps still rely on manual labor, resulting in long testing cycles and high labor costs.

[0004] Therefore, those skilled in the art are dedicated to developing an intelligent connector testing device that facilitates automatic connector testing and improves testing efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent connector testing device, which facilitates automatic testing of connectors and improves testing efficiency.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A connector intelligent testing device, comprising A rotary assembly, on which at least one clamping assembly for clamping a connector is connected; A feeding assembly, wherein the feeding assembly is located on the side wall of the rotary assembly and the output end of the feeding assembly faces the clamping assembly; A detection component is mounted on a base and located on both sides of the rotary component for detecting connectors on the clamping component. A material separating assembly is mounted on the base, with its actuating end facing the clamping assembly and used to separate defective connectors from the clamping assembly.

[0007] The beneficial effects of adopting the above solution are: through the cooperation and coordinated work of the rotary component, clamping component, feeding component, detection component and sorting component, the entire process of connector loading, clamping, detection and sorting is automated, which significantly improves detection efficiency, greatly reduces the time and labor costs of traditional manual operation, and avoids human error through automated sorting, ensuring the consistency and reliability of detection results.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the rotary assembly includes a rotary chain, a first sprocket, and a second sprocket. The two ends of the rotary chain are respectively sleeved on the first sprocket and the second sprocket. The clamping assembly is installed on the rotary chain. The first sprocket is installed on the base through a rotating shaft and a rotating support seat. The second sprocket is connected to a power assembly.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the power component drives the second sprocket, the rotary chain and the first sprocket to rotate in sequence, so that the clamping component installed on the rotary chain rotates and moves the connector conveyed by the feeding component to the detection component, and conveys the qualified connector to the designated position.

[0011] Furthermore, the power component includes a servo motor, the output end of which is sequentially connected to a reducer and a first synchronous pulley. The first synchronous pulley is connected to a second synchronous pulley via a synchronous belt, and the second synchronous pulley is connected to a second sprocket via a connecting shaft.

[0012] The advantages of adopting the above-mentioned further solution are: using a servo motor in conjunction with a synchronous pulley can achieve precise control of the speed of the rotating component and the position of the clamping component, which is conducive to the rapid detection of the connector after the connector is moved to the designated position.

[0013] Furthermore, the clamping assembly includes a clamping seat having a fixing groove for positioning and fixing the connector, and a connecting arm is connected to the upper side of the clamping seat, the other end of which is hinged to the rotary assembly.

[0014] The advantages of adopting the above-mentioned further solution are: the clamping seat has a fixing groove, which facilitates the quick positioning and fixing of the connector, and the clamping seat is connected to the rotary chain through the connecting arm, so that after the clamping seat moves to the appropriate position, it flips under the action of gravity, and moves the qualified connector to the qualified area.

[0015] Furthermore, the material conveying assembly includes a vibrating feeder, the output end of which is connected to a conveying channel, and the end of the conveying channel is close to the clamping assembly; A limiting cylinder is installed on the conveying channel, and a limiting baffle is installed at the output end of the limiting cylinder. The limiting baffle is located inside the conveying channel.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the cooperation between the vibrating feeding tray and the conveying channel facilitates the automatic orientation and orderly conveying of connectors; the limiting cylinder and baffle can control the feeding rhythm of individual connectors, avoid stacking or collision at the outlet of the conveying channel, ensure the smoothness and reliability of the feeding process, and match the operating frequency of the rotary component.

[0017] Furthermore, the detection assembly includes a first detection component and a second detection component, the first detection component and the second detection component being disposed opposite to each other and located on both sides of the clamping assembly; Both the first detection component and the second detection component include a detector for engaging with the connector end. The detector is connected to a test block, which is connected to the output end of a test cylinder. A slider is mounted on the lower side of the test block, and a slide rail that engages with the slider is mounted on the base.

[0018] The advantages of adopting the above-mentioned further solution are: the test cylinder pushes the test block and detector to move, so that the two detectors, which are set opposite each other, are connected and conductive to both ends of the connector. The signal input and output on the two test blocks are used to determine whether the connector meets the requirements. The cooperation of the slider and slide rail makes the detection block and detector move linearly, preventing the detection head from being misaligned or stuck when docking with the connector.

[0019] Furthermore, the material distribution assembly includes a material distribution plate and a guide block, the guide block being installed at the end of the material distribution plate, and a material distribution groove for the guide block to pass through being provided in the middle of the clamping seat. The end of the material distribution plate is also connected to a material distribution cylinder. The material distribution cylinder pushes the material distribution plate to move so that the guide block is inserted into the material distribution groove and the end of the guide block abuts against the clamping seat. When the rotary assembly drives the clamping seat to rotate, the connector located on the clamping seat slides onto the material distribution plate.

[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: when the detection component detects that the connector does not meet the requirements, the material distribution cylinder pushes the guide block into the material distribution slot and the material distribution plate abuts against the clamping seat to form a guide channel. The non-conforming connector is smoothly slid onto the material distribution plate by the motion of the rotary component itself. The material distribution action is smooth and does not interfere with the qualified products, thus realizing efficient and automated sorting.

[0021] Furthermore, it also includes a positioning component, which includes a protective shell and a positioning strip. The protective shell is a sleeve structure for fitting onto the outer wall of the connector. The positioning strip is disposed inside the protective shell and is a ferromagnetic positioning strip. The weight of the positioning strip exceeds the sum of the weights of the connector and the protective shell. The end face of the clamping seat that contacts the protective shell is provided with a magnet for attracting and restricting the movement of the positioning strip.

[0022] The advantages of adopting the above-mentioned further solution are as follows: Since the pins at both ends of the connector are not uniformly and symmetrically structured, the detector also needs to be equipped with a corresponding socket structure. This requires that the pins and sockets be positioned relative to each other during testing, so that when the detector moves radially towards the end of the connector, the socket inside the detector can be inserted into the pin of the connector. However, because the connector is moved by clamping and pulling the clamp, and because the clamp is driven by a chain, vibration is inevitable during the transmission process, causing the connector to rotate circumferentially on the clamp. This results in a misalignment between the connector pins and the preset detection angle, causing the socket of the detector to not be aligned with the pin of the connector. Generally, the position of the connector needs to be manually corrected before testing is performed again. Secondly, generally, when the connector leaves the factory, a transparent protective cover is needed on the outer wall of the connector to protect the connector, most importantly protecting the pins at the end of the connector from bending. In this solution, when the connector is covered with a protective shell and placed on the clamping base, the weight of the positioning strip exceeds the sum of the weights of the connector and the protective shell, causing the connector and the protective shell to rotate circumferentially. This causes the positioning strip to rotate until it comes into contact with the magnet, where it is attracted and fixed by the magnet, thus limiting the protective shell from continuing to rotate. When the two are in the magnetically engaged position, the connector rotates to the preset detection angle, which facilitates the subsequent alignment and insertion of the detector into the connector pins.

[0023] Furthermore, the positioning assembly also includes a drive roller and a driven roller. The clamping seat has a storage groove with one end open, and the opening faces the end face of the clamping seat that contacts the protective shell. The drive roller is connected to a drive source. The drive roller and the driven roller are rotatably disposed in the storage groove, and the drive roller and the driven roller are connected by belt drive. The bearing surface of the belt is located at the opening, and is used to bear and drive the protective shell to rotate circumferentially. The magnetic attraction force of the magnet on the positioning strip is greater than the traction force of the belt on the protective shell.

[0024] The beneficial effect of adopting the above-mentioned further solution is that, since the protective shell is a sleeve structure, i.e., the outer wall is cylindrical, when the protective shell is placed on the clamping seat, the positioning strip may be exactly at the highest point of the protective shell's circumference, thus keeping the protective shell in a balanced state and preventing it from rotating circumferentially. Therefore, this solution uses a drive roller, a driven roller, and a belt drive to rotate the protective shell circumferentially, causing the positioning strip to be in an unbalanced state, thereby rotating the protective shell to a preset detection angle. Furthermore, since the magnetic attraction of the magnet to the positioning strip is greater than the traction force of the belt on the protective shell, once the positioning strip is attracted and fixed, the continued transmission of the belt will not cause the protective shell to continue rotating, thus preventing the protective shell from causing the connector to rotate away from the preset detection angle.

[0025] Furthermore, the positioning component also includes a push switch, which is electrically connected to the controller of the rotary component. The push switch is located at the end of the clamping seat, and the trigger end of the push switch faces the material distribution plate. The material distribution plate is used to abut the trigger end of the push switch.

[0026] The beneficial effect of adopting the above-mentioned further solution is that, since the clamping seat is driven by a chain, vibrations may occur, causing the detector and connector to misalign even if the connector is at a normal detection angle because the clamping seat has not moved to the corresponding detection position. Therefore, in this solution, when the clamping seat moves to the preset detection position, the material distribution plate is driven to move towards the trigger end of the touch switch, so that it touches the trigger end, thereby detecting whether the clamping seat has moved to the preset detection position. If the material distribution plate does not touch the trigger end, a control signal is sent to the rotary assembly, thereby controlling the rotary assembly to drive the clamping seat to move and adjust its position until the next material distribution plate moves and can touch the trigger end of the press switch.

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "inner," "outer," "circumferential," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connector intelligent detection device includes a rotary assembly 1, on which at least one clamping assembly 3 for clamping a connector 2 is connected. The clamping assembly 3 can position and fix the connector 2 and transport it to a designated position as the rotary assembly 1 moves. The feeding assembly 4 is located on the side wall of the rotary assembly 1 and its output end faces the clamping assembly 3. It is used to accurately feed the connector 2 to be tested onto the clamping assembly 3. The detection component 5 is mounted on the base 33 and is located on both sides of the rotating component 1. It is used to detect the connector 2 on the clamping component 3 and to test the electrical performance of the connector 2. The material sorting component 6 is mounted on the base 33, and the execution end of the material sorting component 6 faces the clamping component 3 and is used to separate the unqualified connector 2 from the clamping component 3, so as to realize the automatic sorting of qualified and unqualified products.

[0034] The rotary assembly 1, clamping assembly 3, conveying assembly 4, detection assembly 5, and distributing assembly 6 are all housed within the detection housing 34. The detection housing 34 provides protection for each assembly and reduces external interference. Furthermore, the rotary assembly 1, conveying assembly 4, detection assembly 5, and distributing assembly 6 are all electrically connected to the control assembly 35. The control assembly 35 can coordinate and control the actions of each assembly to achieve automated operation of the device.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the rotary assembly 1 includes a rotary chain 7, a first sprocket 8, and a second sprocket 9. The two ends of the rotary chain 7 are respectively fitted onto the first sprocket 8 and the second sprocket 9 to form a closed transmission circuit. The clamping assembly 3 is mounted on the rotary chain 7 and moves with the rotation of the rotary chain 7. The first sprocket 8 is mounted on the base 33 via a rotating shaft 10 and a rotating support 11. The second sprocket 9 is connected to a power assembly. The power provided by the power assembly drives the second sprocket 9 to rotate, thereby driving the rotary chain 7 to circulate, thus realizing the circulation of the clamping assembly 3 between various workstations. In one embodiment, the power assembly includes a servo motor 12. The output end of the servo motor 12 is sequentially connected to a reducer 13 and a first synchronous pulley 14. The reducer 13 can convert the high-speed rotation of the servo motor 12 into a suitable rotational speed. The first synchronous pulley 14 is connected to a second synchronous pulley 16 via a synchronous belt 15. The second synchronous pulley 16 is connected to the second sprocket 9 via a connecting shaft 17. When the servo motor 12 starts, the power is transmitted sequentially through the reducer 13, the first synchronous pulley 14, the synchronous belt 15, the second synchronous pulley 16 and the connecting shaft 17 to the second sprocket 9, which drives the second sprocket 9 to rotate, thereby achieving precise control of the speed and position of the rotary chain 7, ensuring that the clamping assembly 3 can accurately reach the designated work position.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in another embodiment, the clamping assembly 3 includes a clamping seat 18 with a fixing groove 19 for positioning and fixing the connector 2. The shape of the fixing groove 19 matches the connector 2, enabling quick positioning of the connector 2 and preventing it from falling off during transport. A connecting arm 20 is connected to the upper side of the clamping seat 18, and the other end of the connecting arm 20 is hinged to the rotary assembly 1. The hinged structure allows the clamping seat 18 to maintain an upward-facing opening under gravity when moving with the rotary chain 7, facilitating the reception of the connector 2 conveyed by the feeding assembly 4. When it moves to the unloading position, it can flip under gravity to release the qualified connector 2 to the designated area. When it moves to the upper side of the feeding assembly 4 again, it flips under gravity again, causing the fixing groove 19 on the clamping seat 18 to face upward.

[0037] like Figure 1 , Figure 2 and Figure 5As shown, in one embodiment, the feeding assembly 4 includes a vibrating feeding plate 21. The output end of the vibrating feeding plate 21 is connected to a conveying channel 22. The vibrating feeding plate 21 uses vibration to orient the disordered connectors 2, causing them to enter the conveying channel 22 in a preset posture. The end of the conveying channel 22 is close to the clamping assembly 3, facilitating the conveying of the arranged connectors 2 to the clamping seat 18 of the clamping assembly 3. A limiting cylinder 23 is installed on the conveying channel 22, and a limiting baffle is installed at the output end of the limiting cylinder 23. The limiting baffle is located inside the conveying channel 22. When the clamping assembly 3 reaches the receiving position, the limiting cylinder 23 retracts, causing the limiting baffle to retract from the conveying channel 22, allowing a single connector 2 to pass through and fall into the fixing groove 19 of the clamping seat 18. Subsequently, the limiting cylinder 23 extends, causing the limiting baffle to reset, blocking subsequent connectors 2, thereby precisely controlling the feeding rhythm and preventing the connectors 2 from accumulating at the end of the conveying channel 22.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiment, the detection component 5 includes a first detection component and a second detection component. The first and second detection components are arranged opposite each other and are located on both sides of the clamping component 3. Both the first and second detection components include a detector 24 for mating with the end of the connector 2. The detector 24 is connected to a test block 25, which is electrically connected to the control component 35. One test block 25 inputs a signal to the detector 24, while the other test block 25 and detector 24 receive an output signal and transmit the detection signal to the control component 35. The test block 25 is connected to the output end of the test cylinder 26. When the clamping component 3 carries the connector 2 to the detection station, the test cylinder 26 extends and pushes the test block 25 and detector 24 toward the connector 2, so that the detector 24 mates with the pins at the end of the connector 2. After the detection is completed, the test cylinder 26 retracts, causing the detector 24 to reset. A slider 27 is installed on the underside of the test block 25, and a slide rail 28 that cooperates with the slider 27 is installed on the base 33. The cooperation between the slider 27 and the slide rail 28 provides guidance for the movement of the test block 25, ensuring that the detector 24 can accurately and smoothly dock with the connector 2, thereby improving the accuracy and reliability of the detection.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the material distribution component 6 includes a material distribution plate 29 and a guide block 30. The guide block 30 is installed at the end of the material distribution plate 29 and is inclined. The clamping seat 18 has a material distribution groove 32 in the middle for the guide block 30 to pass through. The end of the material distribution plate 29 is also connected to a material distribution cylinder 31. The material distribution cylinder 31 pushes the material distribution plate 29 to move so that the guide block 30 is inserted into the material distribution groove 32 and the end of the guide block 30 abuts against the clamping seat 18, forming a guiding slope. When the rotary component 1 drives the clamping seat 18 to continue rotating, under the combined action of gravity and the movement of the clamping seat 18, the connector 2 located on the clamping seat 18 slides onto the material distribution plate 29 and slides into the defective product collection box, realizing the automatic separation of defective products. When the connector 2 is qualified, the material distribution cylinder 31 does not move, the guide block 30 is in the initial position, and the qualified connector 2 is released and falls into the qualified product box when it moves to the unloading position with the clamping seat 18.

[0040] Example 2: The difference between this embodiment and the previous embodiment is that, as Figure 7 As shown, the pins at both ends of connector 2 are not uniformly and symmetrically structured. Similarly, detector 24 also needs to be equipped with a corresponding socket structure. This requires that the pins and sockets be positioned relative to each other during detection, so that when detector 24 moves radially toward the end of connector 2, the socket inside detector 24 can be inserted into the pin of connector 2. However, since the aforementioned embodiment uses clamping seat 18 to move connector 2, and since clamping seat 18 is driven by chain 7, vibration is inevitable during transmission, causing connector 2 to rotate circumferentially on clamping seat 18. This causes the pins of connector 2 to deviate from the preset detection angle, resulting in the socket of detector 24 not being aligned and inserted into the pin of connector 2. Generally, it is necessary to manually correct the position of connector 2 and then perform detection again. Secondly, generally, connector 2 needs to have a transparent protective cover on its outer wall at the factory to protect connector 2, most importantly, to protect the pins at the end of connector 2 from bending. Therefore, this embodiment makes further improvements based on embodiment one to solve the above problems.

[0041] Please see Figure 6The system also includes a housing assembly 37, which is located at the front end of the feeding assembly 4. Before the feeding assembly 4 receives the material, the housing assembly 37 first covers the outer wall of the connector 2 with a protective shell 361. The housing assembly 37 is existing technology and includes a three-mode robot 371 and a feeding unit 372 for storing and conveying the protective shell 361. The three-mode robot 371 picks up the protective shell 361 from the discharge end of the feeding unit 372 and then fits it onto the outer wall of the connector 2. It should be noted that when the three-mode robot 371 covers the connector 2 with the protective shell 361, the connector 2 is presumably already aligned with the protective shell 361. This ensures that the positioning strip 362 inside the protective shell 361 is in a preset relative position to the pins of the connector 2. When the positioning strip 362 rotates to contact the end of the clamping seat 18, the pins of the connector 2 have rotated to a preset detection position, facilitating the subsequent alignment and insertion of the detector 24 into the pins of the connector 2.

[0042] Please see Figure 7The system also includes a positioning component 36, which comprises a protective shell 361 and a positioning strip 362. The protective shell 361 is a cylindrical structure with openings at both ends, made of transparent insulating and magnetically shielding material. It can both wrap and protect the outer wall of the connector 2, preventing its end pins from being bent during transportation, and does not affect the observation of the installation status of the connector 2. The outer wall of the protective shell 361 is provided with a positioning strip 362, which is set along the length of the protective shell 361. The side of the positioning strip 362 facing away from the protective shell 361 is an arc surface, and the arc surface is located on the outer wall of the protective shell 361. The radius of curvature of the arc surface is equal to the radius of curvature of the protective shell, thus forming a continuous arc surface between the protective shell 361 and the positioning strip 362. The inner diameter of the protective shell 361 is adapted to the outer diameter of the connector 2. Installation is accomplished through the shell assembly 37. The three-mode robot 371 of the shell assembly 37 grasps the protective shell 361 output from the feeding unit 372 and places it onto the outer wall of the connector 2. After installation, the positioning strip 362 and the pins of the connector 2 are in a preset relative position. The positioning strip 362 is ferrous, and its weight exceeds the sum of the weights of the connector 2 and the protective shell 361, allowing it to drive the connector 2 and the protective shell 361 to rotate. The end face of the clamping seat 18 that contacts the protective shell 361 is provided with a magnet 364 for attracting and restricting the movement of the positioning strip 362. When the positioning strip 362 rotates to a position where it is magnetically attracted to the magnet 364, the rotation of the fixed positioning strip 362 is restricted. This position can be set as a preset detection angle for the connector 2 as needed. It should be noted that the clamping base 18 body, the material distribution plate 29, and the guide block 30 must be non-magnetic to avoid affecting the magnetic attraction between the positioning strip 362 and the magnet 364. When the connector 2 is fitted with the protective shell 361 and placed on the clamping base 18, the weight of the positioning strip 362 exceeds the combined weight of the connector 2 and the protective shell 361, causing the connector 2 and the protective shell 361 to rotate circumferentially. This causes the positioning strip 362 to rotate until it contacts the magnet 364, where it is attracted and fixed, thus limiting the continued rotation of the protective shell 361. When the two are in the magnetically engaged position, the connector 2 rotates to the preset detection angle, facilitating the subsequent alignment and insertion of the detector 24 into the pins of the connector 2.

[0043] Please continue reading. Figure 7Since the protective shell 361 is cylindrical, when the protective shell 361 is placed on the clamping seat 18, the positioning strip 362 may be exactly at the highest point of the protective shell 361's circumference, thus keeping the protective shell 361 in a balanced state and preventing it from rotating circumferentially. Therefore, the positioning assembly 36 also includes a drive roller 365 and a driven roller 366. The clamping seat 18 has a storage groove 181 with one open end, and the opening faces the end face of the clamping seat 18 that contacts the protective shell 361. The drive roller 365 is connected to a micro drive motor. The drive roller 365 and the driven roller 366 are rotatably disposed in the storage groove 181. There are two driven rollers 366 and one drive roller 365. The three are arranged in a triangular structure, and the drive roller 365 and the driven roller 366 are connected by a belt 367. The bearing surface of the belt 367 is... Located at the opening, when the protective shell 361 is placed on the clamping seat 18, the protective shell 361 will contact the bearing surface of the belt 367, thereby driving the protective shell 361 to rotate circumferentially, causing the positioning strip 362 to rotate until it contacts the magnet 364. The magnetic attraction force of the magnet 364 on the positioning strip 362 is greater than the traction force of the belt 367 on the protective shell 361. After the positioning strip 362 is attracted and fixed, the continued transmission of the belt 367 will not drive the protective shell 361 to continue rotating, thereby preventing the protective shell 361 from driving the connector 2 to rotate to a position deviating from the preset detection angle.

[0044] Please continue reading. Figure 7 Because the clamping seat 18 is driven by a chain, it will generate vibrations, which will cause the detector 24 to not correspond to the connector 2 even if the connector 2 is at the normal detection angle, since the clamping seat 18 has not moved to the corresponding detection position. Therefore, the positioning component 36 also includes a push switch 363, which is electrically connected to the controller of the rotary component 1. The push switch 363 is located at the end of the clamping seat 18, and the trigger end of the push switch 363 faces the material distribution plate 29, which is used to abut the trigger end of the push switch 363. When the clamping seat 18 moves to the preset detection station, the drive plate 29 moves towards the trigger end of the touch switch 363, causing it to contact the trigger end. This detects whether the clamping seat 18 has moved to the preset detection station. If the plate 29 moves without contacting the trigger end, a control signal is sent to the rotary assembly 1, which then controls the rotary assembly 1 to drive the clamping seat 18 to move and adjust its position until the plate 29 moves again and contacts the trigger end of the touch switch 363. It should be noted that since the plate 29 needs to separate the defective connectors 2, when the plate 29 moves and contacts the touch switch 363, the guide block 30 will not contact the protective shell 361 because the clamping seat 28 does not continue to move. Therefore, the connectors 2 will not be separated at this time. Only when the clamping seat 28 continues to move and the guide block 30 is in the extended state will the protective shell 361 contact the guide block 30, thereby screening out the defective connectors 2.
