Description

Technical Field

[0001] This application relates to the technical field of automatic assembly of parts, and in particular to an automatic spring inserter device and an automatic spring inserter method. Background Technology

[0002] Circular connectors are a type of electrical connector. Broadly speaking, circular connectors include low-frequency circular connectors, radio frequency coaxial connectors, and audio connectors. Circular connectors are known for their high strength and stable connection. A circular connector consists of a housing and an inner core. The inner core is assembled inside the housing, and a retaining clip, also known as a spring, snap ring, or latch, is installed between the housing and the inner core.

[0003] Currently, in circular connectors, retaining rings are primarily assembled by first clamping the retaining ring with a clamping fixture to limit its position and compress it. At this point, the diameter of the retaining ring is smaller than the diameter of the housing, and the retaining ring is kept coaxial with the housing. A push rod then pushes the retaining ring, compressing it and assembling it into the housing. In this assembly process, because the push rod needs to be coaxial with both the retaining ring and the housing, after assembling the retaining ring into the housing, the housing needs to be unloaded, and then the retaining ring and housing need to be reloaded separately. Therefore, current retaining ring assembly equipment is inefficient. Summary of the Invention

[0004] To improve the efficiency of snap ring assembly, this application provides an automatic snap ring insertion device and an automatic snap ring insertion method.

[0005] In a first aspect, this application provides an automatic spring inserter, which adopts the following technical solution:

[0006] An automatic spring inserter device, comprising:

[0007] An assembly block having a moving channel, a feeding channel fixed on the assembly block, the feeding channel having a vertical part, the vertical part being perpendicular to the moving channel;

[0008] A clamping fixture is slidably disposed within the moving channel. The clamping fixture includes a first clamping part and a second clamping part. The first clamping part is connected to the second clamping part. Each of the first clamping part and the second clamping part has a clamping groove on its opposite side. When the first clamping part and the second clamping part are in contact, the two clamping grooves are used to maintain the compressed state of the retaining spring.

[0009] The pressing mechanism includes a pressure bar slidably disposed on the assembly block and a first driving member for driving the pressure bar to move axially along the clamping groove, the pressure bar being perpendicular to the moving channel;

[0010] The clamping fixture slides back and forth between the feed channel and the pressure rod. When the clamping fixture moves to the position of the feed channel, the retaining spring can enter the clamping groove. When the clamping fixture moves to the pressing mechanism, the pressure rod can move the retaining spring for assembly.

[0011] Based on the above technical solution, the clamping fixture can maintain the compression state of the snap ring, and the clamping fixture can reciprocate between the feeding channel and the pressing mechanism, thereby automatically realizing the feeding and pressing of the snap ring. After pressing the snap ring, it can automatically feed the material, and the pressing efficiency of the snap ring is high.

[0012] Preferably, the first clamping part and the second clamping part are floatingly connected. When the first clamping part and the second clamping part move to the feed channel position, they separate from each other so that the retaining spring can enter the clamping groove. When the first clamping part and the second clamping part move to the pressing mechanism, they fit together to maintain the compressed state of the retaining spring.

[0013] Based on the above technical solution, when the retaining spring is not under force, the diameter of the retaining spring is relatively large. Therefore, during the process of feeding the retaining spring, the separation of the first clamping part and the second clamping part can allow the retaining spring to smoothly enter the clamping groove, which facilitates the automatic feeding of the retaining spring.

[0014] Preferably, a connecting rod is connected between the first clamping part and the second clamping part, and a floating spring is sleeved on the connecting rod. The floating spring is used to separate the first clamping part and the second clamping part from each other.

[0015] Based on the above technical solution, the connection rod and floating spring can enable the first clamping part and the second clamping part to both approach each other to clamp the snap ring and separate from each other, so that the snap ring can smoothly enter the clamping groove.

[0016] Preferably, a limiting rod is slidably provided on the assembly block. The limiting rod is located below the feeding channel and is used to restrict the movement path of the first clamping part, so that the first clamping part and the second clamping part are separated from each other.

[0017] Based on the above technical solution, the limiting rod moves into the space between the first clamping part and the second clamping part, which limits the first clamping part. The second clamping part continues to move under the action of the driving member, which can realize the separation between the first clamping part and the second clamping part, and facilitate the snap ring to enter between the first clamping part and the second clamping part.

[0018] Preferably, the assembly block is provided with a limit trigger rod, and a sliding groove is formed in the assembly block. The limit trigger rod is slidably disposed in the sliding groove. One end of the limit trigger rod extends into the moving channel, and the other end of the limit trigger rod is hinged to one end of a driving lever. The other end of the driving lever is hinged to the limit rod. A support rod is fixedly provided on the assembly block. The support rod is hinged to the middle part of the driving lever to form a hinge point, and the hinge point is closer to the limit trigger rod.

[0019] Or / and, the limit trigger rod extends to one end of the moving channel and is provided with an inclined surface that cooperates with the second clamping part;

[0020] Alternatively, a reset spring is sleeved on the limiting trigger rod. When the second clamping part disengages from the limiting trigger rod, the reset spring is used to reset the limiting trigger rod.

[0021] Based on the above technical solution, when the second clamping part abuts the limiting trigger rod, the limiting trigger rod abuts the driving lever, causing the driving lever to abut the limiting rod to move. The limiting rod moves into the moving channel and plays a limiting role on the first clamping part, so that the first clamping part can be separated from the second clamping part. During the movement of the second clamping part, the limiting rod can be triggered, so that the snap ring can smoothly enter between the first clamping part and the second clamping part.

[0022] Preferably, a limiting slot is provided on the opposite side of the first clamping part and the second clamping part, and the shape of the limiting slot corresponds to the shape of the limiting trigger rod, so that the limiting trigger rod limits the first clamping part.

[0023] Based on the above technical solution, the setting of the limiting slot allows the limiting rod to smoothly enter between the first clamping part and the second clamping part, so that the first clamping part and the second clamping part can be smoothly separated.

[0024] Preferably, the assembly block is provided with a second driving member, the driving part of the second driving member being connected to the second clamping part for driving the clamping fixture to move.

[0025] Based on the above technical solution, the second driving component is used to drive the clamping fixture to move, so that the clamping fixture slides back and forth in the moving channel.

[0026] Preferably, the feeding channel further includes a feeding section, the cross-section of which is configured as an inverted frustum; the clamping groove has a chamfer on the side facing the feeding channel.

[0027] Based on the above technical solution, the cross-sectional area of ​​the feed port side of the feeding part is larger, so the retaining spring can enter the feeding channel more smoothly. At the same time, since the clamping groove has a chamfer on the side facing the feeding channel, the retaining spring can also enter the clamping groove more smoothly.

[0028] Preferably, the assembly block is connected to a first pressing guide block and a second pressing guide block. The first pressing guide block is provided with a first guide groove for the pressure rod to pass through, and the second pressing guide block is provided with a second guide groove for the pressure rod and the retaining spring to pass through.

[0029] Based on the above technical solution, the first pressing guide block and the second pressing guide block can guide and limit the pressing rod, and the second pressing guide block can also guide the snap ring, so that the snap ring can be pressed smoothly.

[0030] Secondly, this application provides an automatic spring inserting method, which adopts the following technical solution:

[0031] An automatic reed insertion method, using the automatic reed insertion device as described above, includes the following steps:

[0032] Place the retaining ring into the feed channel, so that the retaining ring enters the clamping groove from the feed channel;

[0033] Move the first clamping part and the second clamping part so that the first clamping part, the snap ring and the second clamping part are moved to the position of the pressing mechanism;

[0034] The first clamping part and the second clamping part are used to keep the retaining spring in a compressed state;

[0035] Press down the pressure rod so that it abuts against the retaining spring to perform a pressing operation;

[0036] Alternatively, when the retaining ring enters the clamping groove, the first clamping part and the second clamping part separate from each other to create a gap for the retaining ring to enter the clamping groove.

[0037] Based on the above technical solution, the retaining ring enters the clamping groove between the first clamping part and the second clamping part. During the movement of the first clamping part and the second clamping part, the retaining ring is kept in a compressed state. When the first clamping part and the second clamping part drive the retaining ring to the position of the pressing mechanism, the pressing mechanism can realize the pressing of the retaining ring. Since the first clamping part and the second clamping part can move back and forth between the feeding channel and the pressing mechanism, the retaining ring can be automatically fed smoothly after pressing, and the pressing efficiency of the retaining ring is higher.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. The clamping fixture can keep the snap ring in a compressed state, and the clamping fixture can reciprocate between the feeding channel and the pressing mechanism, thereby automatically realizing the feeding and pressing of the snap ring. After pressing the snap ring, it can automatically feed the new material, and the snap ring pressing efficiency is high.

[0040] 2. The limiting rod moves into the space between the first clamping part and the second clamping part, which limits the first clamping part. The second clamping part continues to move under the action of the driving member, which can realize the separation between the first clamping part and the second clamping part, and facilitate the snap ring to enter between the first clamping part and the second clamping part.

[0041] 3. When the second clamping part abuts against the limit trigger rod, the limit trigger rod abuts against the drive lever, causing the drive lever to abut against the limit rod and move. The limit rod moves into the moving channel and limits the first clamping part, so that the first clamping part can be separated from the second clamping part. During the movement of the second clamping part, the limit rod can be triggered, so that the snap ring can smoothly enter between the first clamping part and the second clamping part.

[0052] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0053] This application discloses an automatic spring inserter.

[0054] Example 1:

[0055] Reference Figure 1 The automatic spring inserter includes a support base 10, an assembly block 20 disposed above the support base 10, a clamping fixture 30 disposed within the assembly block 20, and a pressing mechanism 40 disposed on the assembly block 20.

[0056] Reference Figure 2 and Figure 3 The assembly block 20 has a horizontal moving channel 21, and the clamping fixture 30 is slidably disposed in the moving channel 21. A feeding block 50 is fixedly connected to the assembly block 20, and a feeding channel 51 is provided in the feeding block 50, with the axis of the feeding channel 51 perpendicular to the moving channel 21. The pressing mechanism 40 includes a pressure rod 41 that is slidably connected to the assembly block 20 in a vertical direction, with the axis of the pressure rod 41 perpendicular to the moving channel 21. The clamping fixture 30 reciprocates between the feeding channel 51 and the pressing mechanism 40. The retaining spring enters the clamping fixture 30 from the feeding channel 51, and the clamping fixture 30 moves the retaining spring to the position of the pressing mechanism 40. The clamping fixture 30 can maintain the retaining spring in a compressed state, thus allowing the retaining spring to be pressed smoothly.

[0057] Reference Figure 3 The feeding channel 51 has a vertical part 511 and a feeding part 512. The cross-section of the feeding part 512 is set as an inverted frustum shape. The cross-sectional area of ​​the feeding part 512 gradually decreases from top to bottom. The snap ring enters the vertical part 511 from the feeding part 512 and then enters the clamping fixture 30 from the vertical part 511. The clamping fixture 30 keeps the snap ring in a compressed state, which can realize automatic feeding after the snap ring is pressed in, and the feeding efficiency is high.

[0058] Reference Figure 2 and Figure 3 The pressing mechanism 40 also includes a first driving member 42 fixedly connected above the assembly block 20. The first driving member 42 is configured as a driving cylinder, and its drive shaft is fixedly connected to the pressure rod 41. Mounting holes are provided on both the upper and lower side walls of the assembly block 20. A first pressing guide block 60 is fixedly connected to the upper mounting hole, and a second pressing guide block 70 is fixedly connected to the lower mounting hole. The first pressing guide block 60 has a first guide groove for the pressure rod 41 to pass through, and the second pressing guide block 70 has a second guide groove for the pressure rod 41 and the retaining ring to pass through. Under the driving action of the first driving member 42, the pressure rod 41 moves downward, abutting against the retaining ring, causing the retaining ring to move from the clamping fixture 30 into the second guide groove, and then be pressed into the circular connector through the second guide groove, thus achieving automatic pressing of the retaining ring.

[0059] Reference Figure 3 and Figure 4The clamping fixture 30 includes a first clamping part 31 and a second clamping part 32, which are floatingly connected. Each of the first clamping part 31 and the second clamping part 32 has a clamping groove 33 on its opposite side. When the first clamping part 31 and the second clamping part 32 are in contact, the shapes of the two clamping grooves 33 match the shape of the retaining spring in its compressed state, thus maintaining the retaining spring's compressed state. When the first clamping part 31 and the second clamping part 32 are separated, the retaining spring in its natural state can easily enter the clamping groove 33.

[0060] Reference Figure 2 and Figure 5 A connecting rod 34 connects the first clamping part 31 and the second clamping part 32. A floating spring 35 is sleeved on the connecting rod 34. The floating spring 35 is used to separate the first clamping part 31 and the second clamping part 32 from each other. Each of the first clamping part 31 and the second clamping part 32 has a receiving groove for accommodating the floating spring 35 on its opposite side. The two ends of the floating spring 35 are fixedly connected to the two receiving grooves respectively. In its natural state, the first clamping part 31 and the second clamping part 32 are close to each other. When the first clamping part 31 and the second clamping part 32 are separated from each other, the floating spring 35 is in a stretched state.

[0061] Reference Figure 5 A limiting block 36 is fixedly connected to the assembly block 20. The limiting block 36 is located at one end of the moving channel 21. The limiting block 36 is opposite to the second driving member 37. The limiting block 36 is used to limit the clamping fixture 30. Under the pushing force of the second driving member 37, the first clamping part 31 is limited by the limiting block 36. The second clamping part 32 can press the first clamping part 31 to maintain the compressed state of the snap ring.

[0062] Reference Figure 5 The assembly block 20 is provided with a second driving member 37. The driving part of the second driving member 37 is connected to the second clamping part 32 and is used to drive the clamping fixture 30 to move, so that the clamping fixture 30 reciprocates between the feeding channel 51 and the pressing mechanism 40.

[0063] Reference Figure 5 The clamping groove 33 has a chamfer on the side facing the feeding channel 51, so that when the snap ring is feeding, it can be transferred more smoothly from the feeding channel 51 into the clamping groove 33.

[0064] Reference Figure 3During snap ring assembly, to ensure more precise alignment of the snap ring with the circular connector, the assembly block 20 is floatingly connected above the support base 10. A guide rod 80 is fixedly connected to the support base 10, and a support spring 81 is fitted onto the guide rod 80. A guide hole is provided on the assembly block for the guide rod 80 to pass through, and the guide rod 80 slides in conjunction with the guide hole. A cylinder is fixedly connected to the support base 10, and the piston rod of the cylinder is fixedly connected to the assembly block 20. During snap ring assembly, the cylinder is activated, pulling the assembly block 20 downwards, pressing the support spring 81. The second pressing guide block 70 on the assembly block 20 aligns with the circular connector at the installation station, allowing the snap ring to be more precisely assembled into the circular connector.

[0065] The implementation principle of Example 1 is as follows: When assembling the snap ring, the snap ring is brought into the feed channel 51 by the cooperation of the vibrating material plate and the track. At this time, the clamping fixture 30 is kept at the position of the feed channel 51, that is, the position of the feed channel 51 corresponds to the position of the clamping groove 33, and the first clamping part 31 and the second clamping part 32 in the clamping fixture 30 are separated from each other, so that the snap ring in the natural state can enter the clamping groove 33.

[0066] The second drive unit 37 is activated, and the second drive unit 37 pushes the clamping fixture 30 to move to one side of the pressing mechanism 40. When the first clamping part 31 and the second clamping part 32 move to the end of the moving channel 21, the first clamping part 31 and the second clamping part 32 clamp each other to keep the snap ring in a compressed state. At the same time, the position of the clamping groove 33 corresponds to the position of the pressure rod 41.

[0067] The cylinder is activated, causing it to pull the assembly block 20. The assembly block 20 presses down on the support spring 81, aligning the second pressing guide block 70 on the assembly block 20 with the circular connector at the installation station. The first drive unit 42 is then activated, driving the pressure rod 41 to move downward. The pressure rod 41 abuts the retaining ring, causing the retaining ring to enter the circular connector from the clamping groove 33 and the second guide groove, completing the assembly of the retaining ring in the circular connector.

[0068] Example 2:

[0069] Reference Figure 6 The difference between this embodiment and embodiment 1 is that the assembly block 20 is provided with a limiting structure 90 for limiting the first clamping part 31. The limiting structure 90 is configured to facilitate the separation between the first clamping part 31 and the second clamping part 32.

[0070] Reference Figure 6The limiting structure 90 includes a limiting rod 91 horizontally slidably connected to the assembly block 20, a support rod 92 fixedly connected to the assembly block 20, a drive link 93 hinged to the support rod 92, and a limiting trigger rod 94 hinged to the drive link 93. One end of the drive link 93 is hinged to the limiting rod 91, and the other end of the drive link 93 is hinged to the limiting trigger rod 94. The support rod 92 is connected to the middle of the drive link 93, specifically the position between the two ends. Specifically, the hinge position of the support rod 92 and the drive link 93 is closer to the side of the limiting trigger rod 94, so as to drive the limiting rod 91 to move using the lever principle. The limiting rod 91 is located below the feed channel 51 and is used to limit the movement path of the first clamping part 31, so as to separate the first clamping part 31 from the second clamping part 32.

[0071] Reference Figure 6 The assembly block 20 has a sliding groove, and the limit trigger rod 94 is slidably disposed in the sliding groove. One end of the limit trigger rod 94 extends into the moving channel 21, and the end of the limit trigger rod 94 extending into the moving channel 21 is provided with an inclined surface that cooperates with the second clamping part 32.

[0072] Reference Figure 6 Each of the first clamping part 31 and the second clamping part 32 has a limiting groove 38 on its opposite side, and the shape of the limiting groove 38 corresponds to the shape of the limiting trigger rod 94. The second clamping part 32 moves toward the limiting trigger rod 94 under the drive of the second driving member 37. The second clamping part 32 cooperates with the inclined surface at the end of the limiting trigger rod 94, and the limiting trigger rod 94 moves toward the side of the driving link 93. Under the action of the driving lever, the limiting rod 91 slides toward the moving channel 21 and enters the limiting groove 38, thus limiting the first clamping part 31.

[0073] Reference Figure 6 A reset spring 95 is sleeved on the limit trigger rod 94. When the second clamping part 32 is disengaged from the limit trigger rod 94, the reset spring 95 is used to reset the limit trigger rod 94, so that the second clamping part 32 can slide smoothly in the moving channel 21.

[0074] The implementation principle of Embodiment 2 is as follows: When the second clamping part 32 moves to the position of the limit trigger rod 94, the second clamping part 32 abuts against the limit trigger rod 94, causing the limit trigger rod 94 to move towards the drive link 93. The limit trigger rod 94 abuts against the drive link 93 and swings. The drive link 93 drives the limit rod 91 to move towards the moving channel 21. The limit rod 91 enters the limit slot 38. The second driving member 37 continues to drive the second clamping part 32 to move. The first clamping part 31 is blocked by the limit rod 91, so the first clamping part 31 and the second clamping part 32 are separated from each other.

[0075] In other embodiments, the movement of the limiting rod 91 can also be driven by other methods. Specifically, an air passage can be provided at the end of the limiting rod 91, and the limiting rod 91 can be moved pneumatically. When the second clamping part 32 pushes the trigger limiting rod 91 to move, the trigger limiting rod 91 moves away from the second clamping part 32 and abuts against the pneumatic switch. Airflow enters the air passage and drives the limiting rod 91 to move. The limiting rod 91 enters the limiting slot 38, which can limit the first clamping part 31.

[0076] This application also discloses an automatic reed insertion method. The automatic reed insertion method uses the aforementioned automatic reed insertion device and includes the following steps:

[0077] Place the retaining ring into the feed channel 51, so that the retaining ring enters the clamping groove 33 from the feed channel 51;

[0078] Move the first clamping part 31 and the second clamping part 32 to the position of the pressing mechanism 40.

[0079] The first clamping part 31 and the second clamping part 32 are used to keep the snap ring in a compressed state;

[0080] Press down the pressure rod 41 so that it abuts against the retaining spring to perform the pressing operation;

[0081] When the snap ring enters the clamping groove 33, the first clamping part 31 and the second clamping part 32 separate from each other to create a gap for the snap ring to enter the clamping groove 33.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
