Description

Technical Field

[0001] This invention relates to the field of aerospace connector technology, and in particular to a flexible insertion device for circular connector contacts. Background Technology

[0002] A circular connector consists of a base assembly and contacts. The manufacturing process for a circular connector involves the following steps: contact arrangement, applying alcohol to the base surface, contact pre-assembly, contact pressing, and adjusting the angle of the contact solder cups. Contact pre-assembly refers to inserting the contacts into the sockets of the base assembly, and contact pressing refers to pressing the contacts firmly against the base assembly.

[0003] However, in the current manufacturing of circular connectors, the processes of applying alcohol to the base surface, pre-assembling the contacts, and pressing the contacts in are all done manually. This not only increases the labor intensity and cost but also results in low production efficiency. Furthermore, the quality of manually completed processes is difficult to guarantee, and problems such as inconsistent contact insertion heights are prone to occur, thereby reducing the quality of the produced circular connectors. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible insertion device for circular connector contacts that can reduce manual labor intensity and improve production efficiency and quality.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A flexible insertion device for circular connector contacts, comprising:

[0007] The contact positioning and wetting mechanism is used to position and wet the contact components.

[0008] The contact transfer mechanism includes a fixed platform, a first moving mechanism, a second moving mechanism, and a gripping mechanism. The first moving mechanism is mounted on the fixed platform, the second moving mechanism is mounted on the power output end of the first moving mechanism, and the gripping mechanism is mounted on the power output end of the second moving mechanism. The first moving mechanism is used to drive the second moving mechanism to move along a first direction, and the second moving mechanism is used to drive the gripping mechanism to move along a second direction. There is an angle between the first direction and the second direction.

[0009] A base positioning mechanism is used to position the base assembly, and a gripping mechanism is used to pull the contact from the contact positioning and wetting mechanism and insert the contact into the insertion hole of the base assembly.

[0010] In one embodiment, the first direction and the second direction are perpendicular to each other.

[0011] In one embodiment, the contact positioning and wetting mechanism includes a fixed frame, an alcohol tank, and a positioning member. The alcohol tank is connected to the lower part of the fixed frame and has a receiving groove. The fixed frame has a mounting hole communicating with the receiving groove. The positioning member is installed in the mounting hole and has a positioning hole for inserting the fixed contact member.

[0012] In one embodiment, the contact positioning and wetting mechanism further includes an anti-rotation pad, which is disposed on the positioning member and has an anti-rotation limiting hole that communicates with the positioning hole. The anti-rotation pad is used to fit and limit the position on the contact member.

[0013] In one embodiment, the positioning member has a positioning groove, the anti-rotation pad is disposed in the positioning groove, and the positioning groove communicates with the positioning hole.

[0014] In one embodiment, the alcohol tank is welded or glued to the mounting bracket.

[0015] In one embodiment, the first moving mechanism includes a first driving component and a first mounting slide. The first driving component is mounted on the fixed platform, the first mounting slide is slidably connected to the fixed platform, and the first mounting slide is connected to the power output end of the first driving component; the second moving mechanism is mounted on the first mounting slide.

[0016] In one embodiment, when the first mounting slide slides to a first preset position, the gripping mechanism moves with the first mounting slide to a position corresponding to the contact positioning and wetting mechanism; when the first mounting slide slides to a second preset position, the second moving mechanism moves with the first mounting slide to a position corresponding to the base positioning mechanism.

[0017] In one embodiment, the second moving mechanism includes a second driving component and a second mounting slide. The second driving component is fixedly mounted on the first mounting slide, and the second mounting slide is fixedly connected to the second driving component. The gripping mechanism is fixedly mounted on the second mounting slide. When the gripping mechanism moves with the first mounting slide to the first preset position, the second driving component first drives the second mounting slide to move in the positive direction of the second direction, and the gripping mechanism grips the contact. The second driving component then drives the second mounting slide to move in the opposite direction of the second direction, and the gripping mechanism grips and pulls out the contact. When the second moving mechanism moves with the first mounting slide to the second preset position, the second driving component first drives the second mounting slide to move in the positive direction of the second direction, and the gripping mechanism grips the contact and inserts the contact into the insertion hole of the base assembly. The gripping mechanism releases the contact. The second driving component then drives the second mounting slide to move in the opposite direction of the second direction to reset.

[0018] In one embodiment, the second moving mechanism further includes a pressing mechanism disposed on the second mounting slide, the pressing mechanism being used to press down the contact after the gripping mechanism inserts the contact into the insertion hole of the base assembly.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] 1) The flexible insertion device for circular connector contacts of the present invention uses alcohol for wetting. The contact positioning and wetting mechanism is used to position and wet the contact. When the contact is pressed into the base assembly, the base assembly will be wetted with alcohol, avoiding the problem of manually applying alcohol to the base surface in the traditional method. This reduces the intensity of manual labor and improves production efficiency.

[0021] 2) The flexible insertion device for circular connector contacts of the present invention includes a first moving mechanism driving a second moving mechanism to move along a first direction until the gripping mechanism moves above the contact. Then, the second moving mechanism drives the gripping mechanism to move along a second direction until the gripping mechanism moves to the corresponding position of the contact and grips the contact. Then, the second moving mechanism drives the gripping mechanism to move in the opposite direction of the second direction to pull out the contact. Then, the first moving mechanism drives the second moving mechanism to move in the opposite direction of the first direction until the gripping mechanism moves above the base assembly. Then, the second moving mechanism drives the gripping mechanism to move along the second direction until the gripping mechanism inserts the contact into the base assembly. This automates the contact pre-assembly process, thereby reducing manual labor intensity and improving production efficiency and quality. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Please refer to the following: Figures 1 to 15One embodiment of the circular connector contact flexible insertion device 10 includes a contact positioning and wetting mechanism 100, a contact transfer mechanism 200, and a base positioning mechanism 300. The contact positioning and wetting mechanism 100 is used to position and wet the contact 30. The contact transfer mechanism 200 includes a fixed platform 210, a first moving mechanism 220, a second moving mechanism 230, and a gripping mechanism 240. The first moving mechanism 220 is mounted on the fixed platform 210, the second moving mechanism 230 is mounted on the power output end of the first moving mechanism 220, and the gripping mechanism 240 is mounted on the power output end of the second moving mechanism 230. The first moving mechanism 220 is used to drive the second moving mechanism 230 to move along a first direction, and the second moving mechanism 230 is used to drive the gripping mechanism 240 to move along a second direction. There is an angle between the first direction and the second direction. The base positioning mechanism 300 is used to position the base assembly 20, and the gripping mechanism 240 is used to pull the contact 30 out of the contact positioning and wetting mechanism 100 and insert the contact 30 into the insertion hole 201 of the base assembly 20. In this embodiment, the first direction is the OX axis direction, and the second direction is the OZ axis direction.

[0042] The aforementioned circular connector contact flexible insertion device 10 uses alcohol for wetting. The contact positioning and wetting mechanism 100 is used to position and wet the contact 30. When the contact 30 is pressed into the base assembly 20, the base assembly 20 will be wetted with alcohol, avoiding the traditional problem of manually applying alcohol to the base surface, thereby reducing labor intensity and improving production efficiency.

[0043] Furthermore, the first moving mechanism 220 drives the second moving mechanism 230 to move in the positive direction of the first direction until the gripping mechanism 240 moves above the contact member 30. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move in the positive direction of the second direction until the gripping mechanism 240 moves to the corresponding position of the contact member 30 and grips the contact member 30. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move in the opposite direction of the second direction to pull out the contact member 30. Then, the first moving mechanism 220 drives the second moving mechanism 230 to move in the opposite direction of the first direction until the gripping mechanism 240 moves above the base assembly 20. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move in the positive direction of the second direction until the gripping mechanism 240 inserts the contact member 30 into the base assembly 20. This automates the pre-assembly process of the contact member 30, thereby reducing manual labor intensity and improving production efficiency and quality. After the contact 30 is inserted into the base assembly 20, the second moving mechanism 230 drives the gripping mechanism 240 to move and reset in the opposite direction of the second direction, thus completing a pre-installation fully automated process.

[0044] In one embodiment, the first direction and the second direction are perpendicular to each other. In other embodiments, the angle between the first direction and the second direction can be an acute angle.

[0045] In one embodiment, the contact positioning and wetting mechanism 100 includes a fixing frame 110, an alcohol tank 120, and a positioning member 130. The alcohol tank 120 is connected to the lower part of the fixing frame 110 and forms a receiving groove 102. The fixing frame 110 has a mounting hole 101 communicating with the receiving groove 102. The positioning member 130 is installed in the mounting hole 101 and has a positioning hole 103 for inserting and fixing the contact member 30. It can be understood that the receiving groove 102 stores alcohol, and the alcohol level is higher than the bottom of the contact member 30, so that the contact member 30 is immersed in alcohol. When the contact member 30 is pressed into the base assembly 20, the base assembly 20 will be wetted by alcohol, avoiding the traditional problem of manually applying alcohol to the base surface, thereby reducing labor intensity and improving production efficiency.

[0046] In one embodiment, the circular connector contact flexible insertion device 10 further includes an insertion mechanism for inserting the contact 30 into the positioning hole 103 and the receiving groove 102. It is understood that automating the contact 30 arrangement process reduces manual labor intensity and improves production efficiency.

[0047] In one embodiment, the mounting bracket 110 includes a base 112, a lifting drive mechanism 113, and a mounting bracket body 114. Both the mounting bracket body 114 and the lifting drive mechanism 113 are mounted on the base 112, and the power output end of the lifting drive mechanism 113 is connected to the mounting bracket body 114. It can be understood that the lifting drive mechanism 113 drives the mounting bracket body 114 downwards so that the insertion mechanism inserts the contact member 30 into the positioning hole 103 and the receiving groove 102; similarly, after the contact member 30 is arranged and the insertion mechanism has left the mounting bracket body 114, the lifting drive mechanism 113 drives the mounting bracket body 114 upwards.

[0048] Furthermore, the fixing frame 110 also includes a guide rod mechanism 115, which includes a guide rod 1151 and a guide sleeve 1152. The guide sleeve 1152 is connected to the fixing frame body 114 and slidably sleeved on the guide rod 1151. The guide rod 1151 is mounted on the base 112. It can be understood that the lifting drive mechanism 113 drives the fixing frame body 114 and the guide sleeve 1152 to move downward along the axial direction of the guide rod 1151 so that the insertion mechanism inserts the contact 30 into the positioning hole 103 and the receiving groove 102. Similarly, after the contact 30 is arranged and the insertion mechanism leaves the fixing frame body 114, the lifting drive mechanism 113 drives the fixing frame body 114 and the guide sleeve 1152 to move upward along the axial direction of the guide rod 1151.

[0049] In one embodiment, the contact positioning and wetting mechanism 100 further includes an anti-rotation pad 140, which is disposed on the positioning member 130 and has an anti-rotation limiting hole 105. The anti-rotation limiting hole 105 communicates with the positioning hole 103, and the anti-rotation pad 140 is used to fit and limit the contact member 30. It can be understood that the anti-rotation pad 140 has good elasticity to clamp the contact member 30, that is, the anti-rotation pad 140 plays a role in fixing the contact member 30.

[0050] In one embodiment, the positioning member 130 has a positioning groove 104, and the anti-rotation pad 140 is disposed in the positioning groove 104, which communicates with the positioning hole 103. It is understood that reliably disposing the anti-rotation pad 140 on the positioning member 130 ensures the stability and compactness of the connection between the anti-rotation pad 140 and the positioning member 130.

[0051] In one embodiment, the alcohol tank 120 is welded or glued to the mounting bracket 110, ensuring the stability and compactness of the connection between the alcohol tank 120 and the mounting bracket 110.

[0052] In one embodiment, the first moving mechanism 220 is a first motor drive mechanism. In another embodiment, the first moving mechanism 220 includes a first drive component 221 and a first mounting slide 222. The first drive component 221 is mounted on the fixed platform 210, and the first mounting slide 222 is slidably connected to the fixed platform 210 and connected to the power output end of the first drive component 221. The second moving mechanism 230 is mounted on the first mounting slide 222. It can be understood that the first drive component 221 drives the first mounting slide 222 to slide on the fixed platform 210, and the first mounting slide 222 drives the second moving mechanism 230 to slide, so that the gripping mechanism 240 moves above the contact member 30, so that the contact member 30 can be pulled out subsequently. Then, the first drive component 221 drives the first mounting slide 222 to slide on the fixed platform 210 again, and the first mounting slide 222 drives the second moving mechanism 230 to slide, so that the gripping mechanism 240 grips the contact member 30 and moves it above the base assembly 20.

[0053] In one embodiment, when the first mounting slide 222 slides to the first preset position, the gripping mechanism 240 moves with the first mounting slide 222 to the position corresponding to the contact positioning and wetting mechanism 100; when the first mounting slide 222 slides to the second preset position, the second moving mechanism 230 moves with the first mounting slide 222 to the position corresponding to the base positioning mechanism 300. It is understood that the positioning component 130 is always located below the first preset position. The first mounting slide 222 moves from the reference initial position to the first preset position and stops at the first preset position so that the subsequent gripping mechanism 240 can grip the contact 30 in the positioning component 130. The first mounting slide 222 moves from the first preset position to the second preset position and stops at the second preset position so that the subsequent gripping mechanism 240 can grip the contact 30 and insert it into the insertion hole 201 of the base assembly 20. The movement path of the first mounting slide 222 is set, which reduces the setting of the position sensor 224 and simplifies the structure of the flexible insertion device 10 for the circular connector contact.

[0054] In one embodiment, the second moving mechanism 230 includes a second driving component 231 and a second mounting slide 232. The second driving component 231 is fixedly mounted to the first mounting slide 222, and the second mounting slide 232 is fixedly connected to the second driving component 231. The gripping mechanism 240 is fixedly mounted to the second mounting slide 232. When the gripping mechanism 240 moves with the first mounting slide 222 to a first preset position, the second driving component 231 first drives the second mounting slide 232 to move in the positive direction of the second direction, and the gripping mechanism 240 grips the contact member 30. The second driving component 231 then drives the second mounting slide 232 to move in the positive direction of the second direction. The slide 232 moves in the opposite direction of the second direction, and the gripping mechanism 240 grips and pulls out the contact 30. When the second moving mechanism 230 moves to the second preset position with the first mounting slide 222, the second driving component 231 first drives the second mounting slide 232 to move in the positive direction of the second direction, and the gripping mechanism 240 grips the contact 30 and inserts the contact 30 into the insertion hole 201 of the base assembly 20. The gripping mechanism 240 then releases the contact 30. The second driving component 231 then drives the second mounting slide 232 to move in the opposite direction of the second direction to reset, thus automating the pre-installation process of the contact 30.

[0055] In one embodiment, the second moving mechanism 230 further includes a pressing mechanism 400 disposed on the second mounting slide 232. The pressing mechanism 400 is used to press down the contact 30 after the gripping mechanism 240 inserts the contact 30 into the insertion hole 201 of the base assembly 20. This is understood to automate the automatic pressing of the contact 30 into the base assembly 20, i.e., to automate the contact 30 pressing process. Before the contact 30 pre-assembly process and the contact 30 pressing process, the contact 30 is immersed in alcohol in the receiving tank 102, i.e., at least its bottom end is wetted with alcohol. When the contact 30 is subsequently pressed into the base assembly 20, the alcohol on the surface of the contact 30 contacts the base assembly 20 and wets it, thereby automating the base surface alcohol coating process.

[0056] In one embodiment, the base positioning mechanism 300 is fixed to the fixed platform 210, thus mounting the base positioning mechanism 300 on the fixed platform 210. Further, the base positioning mechanism 300 includes a third drive mechanism 310, a fourth drive mechanism 330, and a base positioning platform 320. The fourth drive mechanism 330 is mounted on the power output end of the third drive mechanism 310, and the base positioning platform 320 is mounted on the power output end of the fourth drive mechanism 330. The third drive mechanism 310 drives the base positioning platform 320 to move along a third direction, and the fourth drive mechanism 330 drives the base positioning platform 320 to move along a direction parallel to the first direction, that is, the fourth drive mechanism 330 drives the base positioning platform 320 to move along the OX axis. An angle exists between each pair of the first direction, the second direction, and the third direction. It is understood that there are multiple insertion holes 201 on the base assembly 20. Therefore, when the first mounting slide 222 slides to the second preset position, the base assembly 20 needs to be moved by the third driving mechanism 310 and the fourth driving mechanism 330 to make the contact 30 correspond to the insertion hole 201 to be pre-installed, so that the contact 30 can be inserted into the insertion hole 201 of the base assembly 20, thereby improving the applicability of the flexible insertion device 10 for circular connector contacts. In this embodiment, the base positioning stage 320 is provided with a positioning area, which is used to position the base assembly 20. The third direction is the OY axis direction.

[0057] It should be noted that the included angles between any two pairs of the first direction, the second direction, and the third direction may be equal or unequal. Furthermore, the included angles between any two pairs of the first direction, the second direction, and the third direction may be acute, right, or obtuse. In this embodiment, the included angles between any two pairs of the first direction, the second direction, and the third direction are equal and all are 90°.

[0058] like Figure 1 , Figure 5 , Figures 7 to 8As shown, in one embodiment, the flexible insertion device 10 for the circular connector contact further includes an optical fiber sensor 111. The optical fiber sensor 111 is mounted on the fixing frame 110 and is electrically connected to the control terminals of the first driving mechanism, the second driving mechanism, and the gripping mechanism 240. When the optical fiber sensor 111 detects the contact 30, the first driving mechanism drives the second driving mechanism and the gripping mechanism 240 to move along a first direction. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move along a second direction so that the gripping mechanism 240 grips the contact 30. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move in the opposite direction of the second direction so that the gripping mechanism 240 pulls out the contact 30. Then, the first driving mechanism drives the second driving mechanism and the gripping mechanism 240 to move in the opposite direction of the first direction until the gripping mechanism 240 is located above the base assembly 20. Then, the second moving mechanism 230 drives the gripping mechanism to move in the opposite direction of the first direction. Mechanism 240 moves along the second direction to insert contact 30 into base assembly 20. Then, second moving mechanism 230 drives gripping mechanism 240 to move in the opposite direction of the second direction. Then, first driving mechanism drives second driving mechanism and gripping mechanism 240 to move along the first direction until pressing mechanism 400 is above base assembly 20. Then, second moving mechanism 230 moves along the second direction so that pressing mechanism 400 presses contact 30 into base assembly 20. At this time, alcohol on the surface of contact 30 wets base assembly 20, thereby automating base surface alcohol coating process, contact 30 pre-assembly process and contact 30 pressing process.

[0059] In one embodiment, the contact transfer mechanism 200 is provided with a position sensor 224, which is used to position the contact transfer mechanism 200 in a reference initial position before activation. In this embodiment, the position sensor 224 is a first photoelectric sensor.

[0060] In one embodiment, the pressing mechanism 400 includes a force-applying component 410 and an elastic pressing component 420. The force-applying component 410 is disposed on and fixedly connected to the second mounting slide 232. The force-applying end of the force-applying component 410 is disposed above the elastic pressing component 420. One end of the elastic pressing component 420 is elastically connected to the force-applying end of the force-applying component 410, and the other end of the elastic pressing component 420 is used to press down the contact member 30. The elastic pressing component 420 is slidably connected to the second mounting slide 232. It is understood that after the gripping mechanism 240 inserts the contact 30 into the socket 201 of the base assembly 20, the second moving mechanism 230 moves as a whole above the contact 30. Then, the second moving mechanism 230 moves as a whole downward until it abuts against the contact 30. Then, the second mounting slide 232 drives the force application component 410 to continue to move downward, thereby causing the elastic pressing component 420 to undergo elastic deformation and generate a downward elastic force. The downward elastic force presses the contact 30 into the socket 201 of the base assembly 20, thus completing the contact 30 pressing process. Moreover, the elastic force of the elastic pressing component 420 gradually increases from zero, that is, the pressure of the elastic pressing component 420 on the contact 30 gradually increases from zero. This effectively reduces the problem of damage to the contact 30 caused by the large impact force generated when the elastic pressing component 420 contacts the contact 30, thereby ensuring the production quality of the circular connector.

[0061] Furthermore, the elastic pressing assembly 420 includes a housing 421 and an elastic element 423. The housing 421 forms a receiving cavity 401, which is used to receive the elastic element 423 and the force-applying end of the force-applying assembly 410. The housing 421 is slidably connected to the second mounting slide 232. It can be understood that the elastic element 423 slides along the inner peripheral wall of the receiving cavity 401, ensuring that the elastic force of the elastic element 423 is directed towards the contact element 30, and the housing 421 provides protection and fixation for the elastic element 423. In this embodiment, a pressing block 422 is provided at the bottom end of the housing 421. It can be understood that the surface of the pressing block 422 is relatively smooth, and the pressing block 422 has an arc-shaped structure, which reduces wear on the contact element and ensures the production quality of the circular connector.

[0062] Furthermore, the elastic element 423 is a spring 4231. It can be understood that, according to Hooke's Law, the elastic force of the spring 4231 is proportional to its deformation. The deformation of the spring 4231 can be adjusted according to the amount of elastic force required to press the contact 30 into the socket 201. Furthermore, the tail end of the spring 4231 has a sharp structure, and the spring 4231 is a ring-shaped spiral. Placing the spring 4231 inside the housing 421 can reduce the damage to the contact 30 caused by the elastic pressing assembly 420, thereby ensuring the production quality of the circular connector.

[0063] Furthermore, when the elastic force generated by the elastic element 423 on the contact element 30 is too small, it is difficult to reliably press the contact element 30 into the socket 201; when the elastic force generated by the elastic element 423 on the contact element 30 is too large, it is easy to press the contact element 30 into the socket 201 too deeply, causing deformation of the contact element 30 and the base assembly 20, or even damage. The elastic force generated by the elastic element 423 on the contact element 30 is proportional to the deformation of the elastic element 423, and the deformation of the elastic element 423 is positively correlated with the downward movement distance of the force application component 410. To ensure that the contact 30 is reliably inserted into the socket 201, reduce the deformation of the contact 30 and the base assembly 20, and ensure that the contact 30 is pressed into the socket 201 to a uniform depth, thus ensuring the production quality of the circular connector, in one embodiment, the pressing mechanism 400 further includes a sensing plate 424 and a second photoelectric sensor 425. The sensing plate 424 is disposed on and fixedly connected to the housing 421, and the second photoelectric sensor 425 is disposed on and fixedly connected to the second mounting slide 232. When the elastic member 423 is relatively stationary with respect to the housing 421, the sensing plate 424 and the second photoelectric sensor 425 are correspondingly positioned. The second photoelectric sensor 425 is used to transmit a signal to the second mounting slide 232. The length of the sensing plate 424 in the height direction is a preset length. It is understandable that the preset deformation of the elastic element 423 is calculated based on the pressure required to press the contact 30 into the socket 201, and then the preset length of the sensing element 424 is obtained from the preset deformation of the elastic element 423. The pressing process is as follows: After the gripping mechanism 240 inserts the contact 30 into the socket 201 of the base assembly 20, the second moving mechanism 230 moves as a whole above the contact 30, and then the second moving mechanism 230 moves as a whole downward until it abuts against the contact 30. Then the second mounting slide 232 drives the force application component 410 to continue to move downward until the elastic element 423 reaches the preset deformation. At this time, because the housing 421 is blocked by the contact 30, the housing 42... 1. The sensor 424 moves upward relative to the second mounting slide 232 by a preset length, that is, the sensor 424 moves upward relative to the second photoelectric sensor 425 by a preset length. At this time, the second photoelectric sensor 425 cannot sense the sensor 424 for a moment and transmits the signal to the second mounting slide 232, causing the second mounting slide 232 to stop moving downward, that is, to stop pressing down, thereby completing the pressing down process of the contact 30. During the pressing process, the elastic force of the elastic member 423 is a suitable pressure, which can reliably insert the contact 30 into the socket 201, reduce the deformation of the contact 30 and the base assembly 20, and ensure that the depth of the contact 30 pressed into the socket 201 is uniform, that is, ensure the production quality of the circular connector.

[0064] Furthermore, in one embodiment, the preset deformation of the elastic element 423 is equal to the preset length of the sensing piece 424. It can be understood that when the elastic element 423 generates the preset deformation, the sensing piece 424 moves upwards relative to the second photoelectric sensor 425 by a preset length. At this time, the second photoelectric sensor 425 momentarily loses the ability to sense the sensing piece 424 and transmits a signal to the second mounting slide 232, causing the second mounting slide 232 to stop moving downwards, i.e., stopping the pressing down, thereby completing the pressing down process of the contact 30. During the pressing process, the elastic force of the elastic element 423 provides appropriate pressure, ensuring that the contact 30 is reliably inserted into the socket 201, reducing the deformation of the contact 30 and the base assembly 20, and ensuring a uniform depth of the contact 30 pressed into the socket 201, thus ensuring the production quality of the circular connector.

[0065] Furthermore, in one embodiment, the receiving cavity 401 of the housing 421 includes a communicating mounting cavity 4011 and a buffer cavity 4012, with the mounting cavity 4011 formed above the buffer cavity 4012. The elastic member 423 and the force-applying end of the force-applying component 410 are both disposed within the mounting cavity 4011, and the force-applying end of the force-applying component 410 is fixedly connected to the elastic member 423, so that the elastic member 423 is suspended above the buffer cavity 4012. It can be understood that when the housing 421 abuts against the contact member 30, the buffer cavity 4012 effectively reduces the impact force of the elastic pressing component 420 on the contact member 30, thereby reducing wear on the contact member 30 and ensuring the production quality of the circular connector.

[0066] Furthermore, the sum of the depth of the buffer cavity 4012 and the preset deformation of the elastic element 423 is equal to the preset length of the sensing sheet 424. The pressing process can be understood as follows: the second moving mechanism 230 moves downward as a whole until it abuts against the contact member 30. Then, the second mounting slide 232 drives the force application component 410 and the elastic member 423 to continue moving downward by the length of the buffer cavity 4012. At this time, the elastic member 423 abuts against the bottom wall of the buffer cavity 4012. Then, the second mounting slide 232 drives the force application component 410 to continue moving downward until the elastic member 423 reaches the preset deformation. During the downward movement of the second mounting slide 232, the housing 421 is blocked by the contact member 30. Therefore, the housing 421 moves upward relative to the second mounting slide 232 by a preset length, that is, the sensing plate 424 moves upward relative to the second photoelectric sensor 425 by a preset length. At this time, the second photoelectric sensor 425 cannot sense the sensing plate 424 for a moment and transmits the signal to the second mounting slide 232, causing the second mounting slide 232 to stop moving downward, that is, to stop pressing, thereby completing the pressing process of the contact member 30.

[0067] In one embodiment, the axis of the receiving cavity 401 coincides with the axis of the contact 30. It is understood that the spring applies pressure to the contact for centering, thereby reliably pressing the contact into the socket of the base assembly, ensuring the manufacturing quality of the circular connector.

[0068] In one embodiment, the force-applying component 410 includes a screw assembly 411 and an adjusting slider 412 connected together. The screw assembly 411 is fixedly connected to the second mounting slide 232, and the adjusting slider 412 is disposed within the receiving cavity 401 of the housing 421. The adjusting slider 412 is slidably connected to the inner peripheral wall of the housing 421, and the adjusting slider 412 elastically abuts against the elastic member 423. It can be understood that the screw assembly 411 and the adjusting slider 412 apply force to the elastic member 423 along the axial direction of the receiving cavity 401, thereby causing the elastic force generated by the elastic member 423 to be directed towards the axial direction of the receiving cavity 401, thereby reliably pressing the contact member 30 into the socket 201, and thus ensuring the production quality of the circular connector.

[0069] In one embodiment, the screw assembly 411 includes a threaded base 4112 and a threaded rod 4111 connected to each other. The threaded rod 4111 is clamped in the threaded base 4112 and connected to the adjusting slider 412. The threaded base 4112 is fixedly connected to the second mounting slide 232.

[0070] In one embodiment, the second mounting slide 232 is provided with a guide press-in seat 430, which has a guide channel. The housing 421 is slidably connected to the inner peripheral wall of the guide channel. It can be understood that the guide press-in seat 430 limits the housing 421, causing it to slide along the inner peripheral wall of the guide channel. This allows the elastic force of the elastic member 423 to point towards the contact member 30, thereby reliably pressing the contact member 30 into the socket 201, thus ensuring the production quality of the circular connector.

[0071] In one embodiment, the pressing mechanism 400 is equipped with a CCD sensor, which is used to identify the position of the socket 201. It is understood that the base assembly 20 has multiple sockets 201, and the position of the socket 201 needs to be identified before pressing, thus improving the accuracy and precision of inserting the socket 201.

[0072] In one embodiment, the base positioning mechanism 300 includes a support body 321 and a positioning frame 322. The support body 321 forms a base mounting position 301, and the positioning frame 322 is disposed around the base mounting position 301. The positioning frame 322 is slidably connected to the support body 321 and is used to fix the base assembly 20. It can be understood that after the base assembly 20 is placed in the base mounting position 301, the positioning frame 322 moves toward the base mounting position 301 to fix the base assembly 20; similarly, after the base assembly 20 and the contact member 30 are pressed together, the positioning frame 322 moves away from the base mounting position 301 to move the circular connector.

[0073] In one embodiment, a first photoelectric sensor identifies a reference initial position to correct the initial position of the circular connector contact flexible insertion device 10. Then, an insertion mechanism grasps the contact 30 and inserts it into the positioning hole 103 and the receiving groove 102 of the contact positioning and wetting mechanism 100, immersing the contact 30 at least partially in the alcohol in the receiving groove 102. This allows the contact positioning and wetting mechanism 100 to position and wet the contact 30. Then, a first moving mechanism 220 drives a second moving mechanism 230 to move along a first direction until a first preset position is reached. At this point, the grasping mechanism 240 moves above the contact 30, and then the second moving mechanism 230 drives the grasping mechanism to move. Mechanism 240 moves along the second direction until the gripping mechanism 240 moves to the corresponding position of the contact member 30 and grips the contact member 30. Then, the second moving mechanism 230 drives the gripping mechanism 240 to move in the opposite direction of the second direction to pull the contact member 30 out of the positioning hole 103. Then, the first moving mechanism 220 drives the second moving mechanism 230 to move in the opposite direction of the first direction until it reaches the second preset position. Then, the third and fourth driving components of the base positioning mechanism 300 jointly drive the base assembly 20 to move until the CCD sensor recognizes the contact member 30 that has been inserted but not yet pressed into the base assembly 20. Then, the second driving component 231 drives the gripping mechanism 240. The second drive assembly 231 moves along the second direction to re-grab the contact 30. Simultaneously, the second drive assembly 231 also drives the second mounting slide 232, the force application assembly 410, and the elastic pressing assembly 420 to move along the second direction until the pressing block 422 abuts against the contact 30. Then, the housing 421 and the pressing block 422 remain stationary. The second drive assembly 231 continues to drive the second mounting slide 232, the force application assembly 410, and the spring 4231 to move along the second direction until the spring 4231 abuts against the bottom wall of the buffer cavity 4012. The opening of the buffer cavity 4012 reduces the impact force of the elastic pressing assembly 420 on the contact 30, ensuring the quality of the contact 30. Then, the housing 421 and the pressing block 422 remain stationary. Without moving, the second drive assembly 231 continues to drive the second mounting slide 232 and the force application assembly 410 to move along the second direction. When the housing 421 moves a preset length distance relative to the second mounting slide 232, the sensing piece 424 also moves a preset length distance relative to the second photoelectric sensor 425. That is, the sensing piece 424 separates from the second photoelectric sensor 425. At this time, the second photoelectric sensor 425 cannot sense the sensing piece 424 and transmit a signal. The second mounting slide 232, which receives the signal, stops moving down, that is, stops pressing down, thereby completing the process of pressing down the contact 30, thereby realizing the automation of the production of contact 30 arrangement, base surface alcohol coating, contact 30 pre-installation and contact 30 pressing in.Furthermore, the preset deformation of spring 4231 is equal to the difference between the preset length of sensing plate 424 and the depth of buffer cavity 4012. By setting the preset length and the depth of buffer cavity 4012, spring 4231 generates a preset deformation, thereby generating a preset elastic force value. This ensures that the pressing block 422 presses the contact 30 into the socket 201 under a preset pressure. This not only ensures that the contact 30 is reliably inserted into the socket 201, but also reduces the deformation of the contact 30 and the base assembly 20, and ensures that the depth of the contact 30 pressed into the socket 201 is uniform, thus ensuring the production quality of the circular connector.

[0075] 1) The flexible insertion device 10 for circular connector contacts of the present invention uses alcohol for wetting. The contact positioning and wetting mechanism 100 is used to position and wet the contact 30. When the contact 30 is pressed into the base assembly 20, the base assembly 20 will be wetted with alcohol, avoiding the problem of manually applying alcohol to the base surface in the traditional way, thereby reducing the intensity of manual labor and improving production efficiency.

[0076] 2) The flexible insertion device 10 for circular connector contacts of the present invention, wherein a first moving mechanism 220 drives a second moving mechanism 230 to move along a first direction until a gripping mechanism 240 moves above the contact 30, then the second moving mechanism 230 drives the gripping mechanism 240 to move along a second direction until the gripping mechanism 240 moves to the corresponding position of the contact 30 and grips the contact 30, then the second moving mechanism 230 drives the gripping mechanism 240 to move in the opposite direction of the second direction to pull out the contact 30, then the first moving mechanism 220 drives the second moving mechanism 230 to move in the opposite direction of the first direction until the gripping mechanism 240 moves above the base assembly 20, then the second moving mechanism 230 drives the gripping mechanism 240 to move along the second direction until the gripping mechanism 240 inserts the contact 30 into the base assembly 20, thereby automating the pre-installation process of the contact 30, thereby reducing the intensity of manual labor and improving production efficiency and product quality.
