Description

Technical Field

[0001] This invention relates to the field of snap ring assembly technology, and more specifically, to snap ring assembly mechanisms, methods, electronic devices, and storage media. Background Technology

[0002] Snap rings are installed in the grooves or holes of shafts in machinery and equipment, serving to prevent axial movement of parts on the shaft or in the hole. If a snap ring is missing or improperly installed, it will directly affect the performance of the machinery and equipment.

[0003] Taking the Electronic Parking Brake (EPB) caliper as an example, the retaining circlip is a core component of the EPB caliper. It works in conjunction with the pushrod to limit the pushrod's position. If the retaining circlip is missing or improperly installed, it will directly affect the braking performance of the EPB caliper.

[0004] Snap rings are typically formed into a C-shape. Current snap ring assembly equipment either suffers from complex device structure / drive methods (requiring multiple drive devices to work together in multiple directions) or has problems with material separation (snap rings often hook each other during material separation, causing the equipment to jam and stop), making it impossible to complete snap ring assembly efficiently and accurately.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a snap ring assembly mechanism, method, electronic device and storage medium, which can efficiently and accurately complete snap ring assembly through a first drive stroke and a second drive stroke of the drive mechanism along the snap ring installation direction.

[0007] According to one aspect of the present invention, a retaining ring assembly mechanism is provided, comprising: a feeding rod; a driving mechanism disposed at the discharge end of the feeding rod and connected to a retaining ring mounting plate, the driving mechanism having a first driving stroke and a second driving stroke along the retaining ring mounting direction; during the first driving stroke, the retaining ring mounting plate moves from an initial state of receiving a retaining ring passing through the feeding rod to a distributing state that allows space for the retaining ring to fall; during the second driving stroke, the retaining ring mounting plate moves from the distributing state to an installation state that receives a retaining ring passing through the feeding rod and pushes a fallen retaining ring to a target position.

[0008] The aforementioned snap ring assembly mechanism achieves snap ring distribution and installation through a first and second drive stroke along the snap ring installation direction. On the one hand, driving the snap ring along the snap ring installation direction simplifies the device structure and drive method of the snap ring assembly mechanism. On the other hand, distributing the snap ring along the snap ring installation direction avoids the ends of the snap rings from hooking together, thereby completing snap ring assembly efficiently and accurately.

[0009] In some embodiments, the retaining ring mounting plate is provided with a hollow portion at the front end and a receiving portion connecting the hollow portion; the hollow portion provides space for the retaining ring to fall in the material distribution state and pushes the fallen retaining ring in the second drive stroke; the receiving portion leaves the discharge end in the first drive stroke and moves to below the discharge end in the second drive stroke.

[0010] The perforated part moves to below the discharge end in the material distribution state, thereby providing space for the snap ring to fall off, and pushes the fallen snap ring in the second drive stroke to realize the installation of the snap ring; the receiving part moves away from the discharge end in the first drive stroke to allow the snap ring at the discharge end to fall off, and moves to below the discharge end in the second drive stroke to receive the snap ring that passes through the material feeding rod.

[0011] In some embodiments, the height of the cutout portion is equivalent to the thickness of a retaining spring.

[0012] The height of the hollow section is equivalent to the thickness of a single retaining spring, allowing for the installation of one retaining spring at a time, ensuring orderly installation of the retaining springs, and ensuring that the remaining retaining springs on the material threading rod are still supported by the receiving part, preventing the retaining springs from becoming misaligned.

[0013] In some embodiments, the shape of the rear wall of the cutout portion is adapted to the outer contour of the retaining spring, and the dimension of the cutout portion perpendicular to the mounting direction of the retaining spring is equivalent to the dimension of the retaining spring perpendicular to the mounting direction of the retaining spring.

[0014] The shape of the back wall of the hollow part is adapted to the outer contour of the retaining spring, which can achieve stable pushing of the retaining spring during installation; the dimension of the hollow part in the vertical retaining spring installation direction is equivalent to the dimension of the retaining spring in the vertical retaining spring installation direction, which can limit the retaining spring during installation, prevent the retaining spring from moving beyond the retaining spring installation direction, and ensure that the retaining spring is accurately installed to the target position.

[0015] In some embodiments, the retaining ring mounting plate is further provided with a limiting step connecting the receiving part; the rear wall shape of the limiting step is adapted to the outer contour of the retaining ring, and the dimension of the limiting step perpendicular to the retaining ring mounting direction is equivalent to the dimension of the retaining ring perpendicular to the retaining ring mounting direction.

[0016] The shape of the rear wall of the limiting step is adapted to the outer contour of the retaining spring, which can achieve stable limiting of the retaining spring on the material feeding rod; the dimension of the limiting step in the direction perpendicular to the retaining spring installation is equivalent to the dimension of the retaining spring in the direction perpendicular to the retaining spring installation, which can prevent the retaining spring on the material feeding rod from moving and ensure the stability of the entire device.

[0017] In some embodiments, the snap ring assembly mechanism further includes a lifting mechanism having a lifting stroke capable of moving to a preset distance from the discharge end.

[0018] The lifting mechanism can raise the object to be installed with the retaining ring to a suitable distance from the discharge end, thereby catching any falling retaining rings and facilitating their installation.

[0019] In some embodiments, the driving mechanism includes a first driving device and a second driving device connected together, and the snap ring mounting plate is connected to the second driving device; during the first driving stroke, the first driving device drives the second driving device and the snap ring mounting plate to move from the initial state to the material dispensing state; during the second driving stroke, the first driving device first drives the second driving device and the snap ring mounting plate to move from the material dispensing state to the initial state, and then the second driving device drives the snap ring mounting plate to move from the initial state to the mounting state.

[0020] The first drive stroke is completed independently by the first drive device. In the second drive stroke, the first drive device returns to its original position first, and then the second drive device continues to execute (the second drive device can return to its original position after the snap ring is installed). In this way, each drive device only needs to execute one set of drive strokes with opposite directions and equal distances. The control is simple and convenient, without the need for multiple strokes to be superimposed. It can also achieve two control accuracies, one coarse (first drive device) and one fine (second drive device), to ensure the accurate distribution and installation of snap rings.

[0021] In some embodiments, the drive mechanism further has a third drive stroke along the circlip mounting direction; during the third drive stroke, the second drive device drives the circlip mounting plate from the mounting state to the initial state.

[0022] Through the third drive stroke, the second drive unit returns to its original position, thus returning the entire drive mechanism to its initial position for the installation of the next retaining ring.

[0023] In some embodiments, the snap ring assembly mechanism further includes: a detection mechanism disposed opposite to the drive mechanism and connected to a snap ring detection plate; the detection mechanism has a detection stroke opposite to the direction of the second drive stroke; during the detection stroke, the snap ring detection plate moves at least to a first detection position corresponding to the target position.

[0024] The testing agency's testing process allows for convenient verification of whether the target position is accurately equipped with a retaining ring after the retaining ring is installed.

[0025] In some embodiments, the front end of the snap ring detection plate is provided with a snap ring contact portion. When the snap ring contact portion moves to abut against the snap ring installed at the target position, the snap ring detection plate stops at the first detection position.

[0026] By abutting and engaging the snap ring contact part with the snap ring installed at the target position, the detection result is obtained that the snap ring is accurately installed at the target position.

[0027] In some embodiments, during the detection stroke, the snap ring detection plate can also move to a second detection position that stops beyond the first detection position.

[0028] If the retaining ring is not accurately installed at the target position, the retaining ring detection plate can move to a stop at the second detection position to obtain the detection result that the retaining ring is not accurately installed at the target position.

[0029] In some embodiments, the snap ring detection plate is provided with a snap ring contact portion at the front end and a limiting groove connecting the snap ring contact portion; when the snap ring installed at the target position is pushed by the snap ring contact portion to abut against the snap ring mounting plate, and / or when the limiting groove moves to abut against the snap ring mounting object, the snap ring detection plate stops at the second detection position.

[0030] If the retaining ring is not installed properly (missing or not installed securely), the retaining ring installed at the target position will be pushed by the retaining ring contact part to abut against the retaining ring mounting plate, or the retaining ring detection plate will move to the limiting groove to abut against the retaining ring installation object, which can achieve reasonable and effective detection and avoid damage caused by excessive detection stroke.

[0031] In some embodiments, the detection mechanism is further connected to any one or more of the following components: a magnetic strip, a pressure reducing valve, and a pressure gauge.

[0032] The magnetic stripe allows for monitoring the movement of the detection mechanism and generating accurate test results; the pressure reducing valve / gauge allows for adjusting / monitoring the pushing force of the detection mechanism on the snap ring detection plate to achieve reasonable and effective testing.

[0033] In some embodiments, the driving mechanism includes a first driving device and a second driving device connected together, the detection mechanism is connected to the first driving device, and the snap ring mounting plate is connected to the second driving device; during the first driving stroke, the first driving device drives the second driving device and the snap ring mounting plate to move from the initial state to the material distribution state, and drives the snap ring detection plate to move to a third detection position that stops beyond the first detection position; during the second driving stroke, the first driving device first drives the second driving device and the snap ring mounting plate to move from the material distribution state to the initial state, and then the second driving device drives the snap ring mounting plate to move from the initial state to the installation state.

[0034] The detection mechanism is connected to the first drive device and can be driven to detect whether a snap ring has been installed at the target position during the first drive stroke of the snap ring dispensing, thus avoiding repeated installation of the snap ring. In addition, the design of connecting the detection mechanism to the first drive device can also make the overall structure of the snap ring assembly mechanism stable and facilitate the arrangement of the snap ring assembly mechanism.

[0035] In some embodiments, the discharge end is provided with a proximity switch, the feed end of the feed rod is connected to a feeding device, and the feeding device is connected to the proximity switch.

[0036] The proximity switch can identify whether there is a retaining ring at the discharge end; the feeding device connected to the feeding end of the feeding rod is connected to the proximity switch, and can supply material in time when the proximity switch detects that there is no retaining ring at the discharge end, so as to ensure the continuous progress of the retaining ring assembly process.

[0037] According to another aspect of the present invention, a snap ring assembly method is provided, applied to the snap ring assembly mechanism described in any of the above embodiments, comprising: controlling the drive mechanism to perform a first drive stroke to cause the snap ring at the end of the discharge end to fall off; and controlling the drive mechanism to perform a second drive stroke to push the fallen snap ring to be installed at the target position.

[0038] The above-described snap ring assembly method controls the drive mechanism to execute a first drive stroke and a second drive stroke along the snap ring installation direction in sequence. The first drive stroke is used to distribute the snap rings, and the second drive stroke is used to install the snap rings. On the one hand, the drive stroke always runs along the snap ring installation direction, which simplifies control. On the other hand, distributing the snap rings along the snap ring installation direction can prevent the ends of the snap rings from hooking together, thereby completing the snap ring assembly efficiently and accurately.

[0039] In some embodiments, the driving mechanism includes a first driving device and a second driving device connected together; the snap ring assembly method further includes: controlling the first driving device to operate during the first driving stroke; and controlling the first driving device to perform a driving stroke that is opposite in direction and equal in distance to the first driving stroke during the second driving stroke, and then controlling the second driving device to operate.

[0040] The first drive stroke controls the first drive device to operate independently. In the second drive stroke, the first drive device is first controlled to return to its original position, and then the second drive device is controlled to operate independently (after the snap ring is installed, the second drive device is controlled to return to its original position). In this way, it is only necessary to control each drive device to execute a set of drive strokes in opposite directions and with equal distances to realize the distribution and installation of snap rings. The control is simple and convenient, without the need for multiple strokes to be superimposed, and can achieve two control accuracies: one coarse (first drive device) and one fine (second drive device) to ensure accurate distribution and installation of snap rings.

[0041] In some embodiments, the snap ring assembly mechanism further includes: a detection mechanism disposed opposite to the drive mechanism, the detection mechanism being connected to the first drive device and having a snap ring detection plate connected thereto; the snap ring assembly method further includes: controlling the drive mechanism to execute the first drive stroke, and also driving the detection mechanism to execute a detection stroke to detect whether a snap ring is installed at the target position; and, after the second drive stroke is completed, controlling the detection mechanism to execute a detection stroke to detect whether the snap ring at the target position is installed in place.

[0042] The detection mechanism connected to the first drive device can be used to detect whether a retaining ring has been installed at the target position during the first drive stroke, thus avoiding repeated installation of the retaining ring. When the second drive stroke is completed, the detection mechanism is controlled to detect whether the retaining ring at the target position is installed in place, thus realizing convenient detection of whether the retaining ring is accurately installed at the target position.

[0043] In some embodiments, the snap ring assembly mechanism further includes: a detection mechanism, which is disposed opposite to the drive mechanism and connected to a snap ring detection plate; the snap ring assembly method further includes: after the second drive stroke is completed, controlling the detection mechanism to perform a detection stroke to detect whether the snap ring at the target position is installed in place.

[0044] The detection mechanism can also be set up independently and not connected to the first drive device; in this case, when the second drive stroke is completed, the detection mechanism is controlled to execute the detection stroke, which can also realize the convenient detection of whether the target position is accurately equipped with a snap ring.

[0045] According to another aspect of the present invention, an electronic device is provided, comprising: a processor; a memory storing executable instructions; wherein, when the executable instructions are executed by the processor, they implement the snap ring assembly method as described in any of the above embodiments.

[0046] Electronic devices can be deployed in or communicate with the snap ring assembly mechanism. By running the snap ring assembly method, the electronic devices can efficiently and accurately control the snap ring assembly mechanism to complete the snap ring assembly.

[0047] According to another aspect of the present invention, a computer-readable storage medium is provided for storing a program that, when executed by a processor, implements the snap ring assembly method as described in any of the above embodiments.

[0048] The storage medium can be executed by a processor deployed in the snap ring assembly mechanism, or by a processor that is communicatively connected to the snap ring assembly mechanism, to control the snap ring assembly mechanism to complete the snap ring assembly efficiently and accurately.

[0049] The beneficial effects of this invention compared to the prior art include at least the following:

[0050] The snap ring assembly scheme of the present invention performs snap ring material distribution and installation through the first and second driving strokes of the driving mechanism along the snap ring installation direction. On the one hand, driving the snap ring along the snap ring installation direction at all times simplifies the device structure and driving method of the snap ring assembly mechanism. On the other hand, distributing the snap ring along the snap ring installation direction avoids the ends of the snap rings from hooking together, thereby completing the snap ring assembly efficiently and accurately.

[0066] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to fully and completely convey the concept of the exemplary embodiments to those skilled in the art.

[0067] The accompanying drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0068] The use of terms such as "first," "second," and similar terms in the specific description does not indicate any order, quantity, or importance, but is merely used to distinguish different components. Furthermore, in the description of this invention, terms such as "upper," "lower," "front," and "rear" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0069] It should be noted that, unless otherwise specified, the embodiments of the present invention and the features in different embodiments can be combined with each other.

[0070] The following embodiments will use EPB calipers as an example to illustrate the snap ring assembly scheme of the present invention. In other scenarios requiring snap ring assembly, such as snap ring assembly of motors, snap ring assembly of steering shafts, etc., the snap ring assembly scheme of the present invention can be used to achieve an efficient and accurate automatic snap ring assembly process of material distribution → installation → inspection.

[0071] Figure 1 The side view shows the EPB caliper with the retaining ring in the assembled state. Figure 2 This shows a top view of the EPB caliper with its snap rings assembled; combined with Figure 1 and Figure 2 As shown, the retaining ring 13 of the EPB caliper 11 is mounted on the push rod 12 and is fitted into the slot of the push rod 12 to play a thrust-stopping role and prevent the push rod 12 from falling off in the axial direction.

[0072] Current snap ring assembly equipment requires multiple drive devices to operate in multiple directions. For example, typically at least one drive device is needed to dispense material in one direction, and another drive device is needed to install the snap ring in another direction, resulting in a complex device structure and driving method. Since the snap ring dispensing direction is not the snap ring installation direction, the dispensing usually follows... Figure 2The "y" direction shown is transverse. If the surface of the retaining ring 13 has burrs or the retaining ring 13 is not placed evenly, the end 130 of the retaining ring 13 may hook with other retaining rings during the material distribution process, causing the equipment to jam and stop. In addition, the current retaining ring assembly equipment does not have a complete detection function after the retaining ring is installed, which also needs to be improved.

[0073] The snap ring assembly scheme of the present invention can realize an efficient and accurate automatic snap ring assembly process of material sorting → installation → testing, and solve the problem that current snap ring assembly equipment cannot complete snap ring assembly efficiently and accurately.

[0074] Figure 3 This illustrates the three-dimensional structure of the snap ring assembly mechanism in an embodiment of the present invention. Figure 4 This diagram shows an enlarged view of the snap ring mounting plate of the snap ring assembly mechanism in an embodiment of the present invention; combined with Figure 3 and Figure 4 As shown, the snap ring assembly mechanism provided in this embodiment of the invention includes:

[0075] Threading rod 20;

[0076] The drive mechanism 30 is located at the discharge end 22 of the feed rod 20 and is connected to the snap ring mounting plate 40. The drive mechanism 30 has a first drive stroke and a second drive stroke along the snap ring mounting direction "x".

[0077] During the first drive stroke, the snap ring mounting plate 40 moves from the initial state of receiving the snap ring 50a that is inserted into the material feeding rod 20 to the material distribution state that makes room for the snap ring to fall.

[0078] During the second drive stroke, the snap ring mounting plate 40 moves from the material distribution state to the installation state where it receives the snap ring 50a that is inserted through the material feeding rod 20 and pushes the fallen snap ring 50b to be installed in the target position.

[0079] The aforementioned snap ring assembly mechanism achieves snap ring distribution and installation through the first and second drive strokes of the drive mechanism 30 along the snap ring installation direction "x". On the one hand, driving the snap ring along the snap ring installation direction "x" simplifies the device structure and drive method of the snap ring assembly mechanism. On the other hand, distributing the snap ring along the snap ring installation direction "x" avoids the ends of the snap rings from hooking together, thereby completing the snap ring assembly efficiently and accurately.

[0080] Continue to combine Figure 3 and Figure 4 As shown, in some embodiments, the snap ring assembly mechanism further includes a lifting mechanism 60, which has a lifting stroke capable of moving to a preset distance from the discharge end 22.

[0081] The lifting mechanism 60 can lift the snap ring installation object (EPB clamp 11 in this embodiment) to a suitable distance from the discharge end 22, thereby catching the falling snap ring 50b for snap ring installation. The suitable distance is preferably equivalent to the thickness of a snap ring, for example, 1.1-1.3 times the thickness of a snap ring, so as to achieve one snap ring at a time.

[0082] Figure 5 This invention illustrates the three-dimensional structure of the retaining ring mounting plate in an embodiment of the invention. Figure 6 This diagram shows a top view of the snap ring mounting plate in its initial state in an embodiment of the present invention. Figure 7 This diagram shows a top view of the snap ring mounting plate in a material distribution state in an embodiment of the present invention. Figure 8 This diagram shows a top view of the snap ring mounting plate during its movement from a material distribution state to an installation state in an embodiment of the present invention. Figure 9 This diagram shows a top view of the snap ring mounting plate in the installation state in an embodiment of the present invention; combined with Figures 3 to 9 As shown, in some embodiments, the snap ring mounting plate 40 is provided with a hollow portion 42 located at the front end (in this embodiment, the front end of the snap ring mounting plate 40 refers to the end of the snap ring mounting plate 40 facing the target position) and a receiving portion 44 connecting the hollow portion 42; the hollow portion 42 provides space for the snap ring to fall in the material distribution state and pushes the snap ring 50b that falls in the second drive stroke; the receiving portion 44 leaves the discharge end 22 in the first drive stroke and moves to below the discharge end 22 in the second drive stroke.

[0083] Specifically, combined Figures 3 to 6 As shown, in the initial state, the receiving part 44 is located below the discharge end 22, thereby receiving the retaining spring 50a that passes through the material feeding rod 20. At this time, the lifting mechanism 60 can be controlled to lift the EPB clamp 11 to a suitable distance from the discharge end 22, for example, a distance equal to the thickness of a retaining spring. The design of the hollow part 42 also provides clearance during the lifting phase of the lifting mechanism 60, so that the EPB clamp 11 can be lifted to a suitable distance from the discharge end 22. Combined with Figures 3 to 7 As shown, in the material distribution state, the receiving part 44 moves away from the discharge end 22 to allow the retaining spring of the discharge end 22 to fall off; the hollow part 42 moves to the material distribution area 11' below the discharge end 22 and located at the top of the EPB clamp 11 (the material distribution area 11' is separated from the target position, i.e., the position of the push rod 12), to provide space for the retaining spring to fall into the material distribution area 11'; at this time, part of the retaining spring on the material threading rod 20 falls into the material distribution area 11', i.e. Figure 7 The detached retaining ring 50b is shown in the image. Combined with... Figures 3 to 5 , Figure 7 and Figure 8As shown, during the second drive stroke, the hollowed-out portion 42 pushes the fallen retaining spring 50b toward the push rod 12, and the receiving portion 44 moves toward the discharge end 22 to receive the retaining spring 50a (which is inserted on the material feeding rod 20). Figure 8 From this perspective, the retaining circlip inserted on the feed rod 20 is stacked on top of the fallen retaining circlip 50b. Figures 3 to 5 , Figure 8 and Figure 9 As shown, in the installation state, the fallen retaining ring 50b reaches the target position and is accurately installed with the push rod 12; the retaining ring 50a on the material threading rod 20 is steadily supported by the receiving part 44.

[0084] In some embodiments, the height of the cutout 42 is approximately equal to the thickness of a retaining spring. Preferably, the height of the cutout 42 is 1.1-1.2 times the thickness of a retaining spring, so as to achieve orderly installation of retaining springs by pushing one retaining spring at a time, and to ensure that the remaining retaining springs 50a passing through the feed rod 20 are still supported by the receiving part 44, thus preventing the retaining springs from becoming misaligned.

[0085] In some embodiments, the shape of the rear wall of the cutout portion 42 is adapted to the outer contour of the retaining ring, and the dimension of the vertical retaining ring mounting direction "x" of the cutout portion 42 is equivalent to the dimension of the vertical retaining ring mounting direction "x" of the retaining ring.

[0086] The shape of the rear wall of the cutout portion 42 is adapted to the outer contour of the retaining ring, which can stably push the retaining ring (i.e., the fallen retaining ring 50b) during installation; the dimension of the vertical retaining ring installation direction "x" of the cutout portion 42 is equivalent to the dimension of the retaining ring vertical retaining ring installation direction "x", which can limit the retaining ring during installation, prevent the retaining ring during installation from moving beyond the retaining ring installation direction "x", and ensure that the retaining ring during installation is accurately installed to the target position.

[0087] Combination Figures 4 to 9 As shown, in some embodiments, the retaining ring mounting plate 40 is further provided with a limiting step 46 for connecting the receiving portion 44; the rear wall shape of the limiting step 46 is adapted to the outer contour of the retaining ring, and the dimension of the limiting step 46 in the vertical retaining ring mounting direction "x" is equivalent to the dimension of the retaining ring in the vertical retaining ring mounting direction "x".

[0088] The shape of the rear wall of the limiting step 46 is adapted to the outer contour of the retaining spring, which can achieve stable limiting of the retaining spring 50a on the feed rod 20; the dimension of the vertical retaining spring installation direction "x" of the limiting step 46 is equivalent to the dimension of the retaining spring installation direction "x", which can prevent the retaining spring 50a on the feed rod 20 from moving, thereby ensuring the stability of the entire device.

[0089] Combination Figures 3 to 9As shown, in some embodiments, the drive mechanism 30 includes a first drive device 32 and a second drive device 33 connected together, and a snap ring mounting plate 40 is connected to the second drive device 33; during the first drive stroke, the first drive device 32 drives the second drive device 33 and the snap ring mounting plate 40 to move from the initial state to the material distribution state; during the second drive stroke, the first drive device 32 first drives the second drive device 33 and the snap ring mounting plate 40 to move from the material distribution state to the initial state, and then the second drive device 33 drives the snap ring mounting plate 40 to move from the initial state to the mounting state.

[0090] The first drive stroke is completed independently by the first drive device 32. In the second drive stroke, the first drive device 32 returns to its original position first, and then the second drive device 33 continues to execute (the second drive device 33 can return to its original position after the snap ring is installed). In this way, each drive device only needs to execute a set of drive strokes with opposite directions and equal distances. The control is simple and convenient, without the need for multiple strokes to be superimposed. It can also achieve two control accuracies, one coarse (first drive device 32) and one fine (second drive device 33), to ensure the accurate distribution and installation of snap rings.

[0091] In some embodiments, the drive mechanism 30 further has a third drive stroke along the snap ring mounting direction "x"; during the third drive stroke, the second drive device 33 drives the snap ring mounting plate 40 to move from the mounting state to the initial state.

[0092] Through the third drive stroke, the second drive unit 33 returns to its original position, thereby returning the entire drive mechanism 30 to its initial position for the installation of the next retaining ring.

[0093] Combination Figure 3 and Figure 4 As shown, in some embodiments, the snap ring assembly mechanism further includes: a detection mechanism 70, which is disposed opposite to the drive mechanism 30 and connected to a snap ring detection plate 77. The detection mechanism 70 has a detection stroke opposite to the direction of the second drive stroke. During the detection stroke, the snap ring detection plate 77 moves at least to a first detection position that stops at the corresponding target position.

[0094] The 70-degree inspection stroke of the inspection mechanism allows for convenient inspection of whether the target position is accurately equipped with a retaining ring after the retaining ring is installed.

[0095] Figure 10 This invention illustrates the three-dimensional structure of the snap ring detection plate in the snap ring assembly mechanism of an embodiment of the present invention. Figure 11 This diagram shows a top view of the detection state of the snap ring assembly mechanism in an embodiment of the present invention; combined with Figure 3 , Figure 4 , Figures 9 to 11As shown, in some embodiments, the front end of the snap ring detection plate 77 (in this embodiment, the front end of the snap ring detection plate 77 refers to the end of the snap ring detection plate 77 facing the target position) is provided with a snap ring contact portion 771. When the snap ring contact portion 771 moves to abut against the snap ring 50b' installed at the target position, the snap ring detection plate 77 stops at the first detection position.

[0096] If the retaining ring 50b' at the target position is installed correctly, it can withstand the detection thrust from the retaining ring detection plate 77, causing the retaining ring contact part 771 to abut against it. Thus, through the abutting engagement between the retaining ring contact part 771 and the retaining ring 50b' installed at the target position, a detection result is obtained that the retaining ring is accurately installed at the target position.

[0097] In some embodiments, during the detection stroke, the snap ring detection plate 77 can also move to a second detection position that stops beyond the first detection position.

[0098] If the snap ring is not accurately installed at the target position, for example, if the snap ring is missing or not installed securely, the snap ring detection plate 77 can continue to move until it stops at the second detection position after reaching the first detection position, thereby obtaining the detection result that the snap ring is not accurately installed at the target position.

[0099] Combination Figure 3 , Figure 4 , Figures 9 to 11 As shown, in some embodiments, the snap ring detection plate 77 is also provided with a limiting groove 772 for connecting the snap ring contact portion 771; when the snap ring 50b' installed at the target position is pushed by the snap ring contact portion 771 to abut against the snap ring mounting plate 40, and / or when the limiting groove 772 moves to abut against the push rod 12, the snap ring detection plate 77 stops at the second detection position.

[0100] If the retaining ring is not installed properly (missing or not installed securely), the retaining ring 50b' installed at the target position will be pushed by the retaining ring contact part 771 to abut against the retaining ring mounting plate 40, or the retaining ring detection plate 77 will move to the limiting groove 772 to abut against the retaining ring installation object, thereby achieving reasonable and effective detection and avoiding damage caused by excessive detection stroke.

[0101] Furthermore, before the detection mechanism 70 drives the snap ring detection plate 77 for detection, the drive mechanism 30 can be controlled to drive the snap ring mounting plate 40 to retract a certain distance to reserve the detection space 770. The retraction distance of the snap ring mounting plate 40 does not need to be too large to prevent excessive detection stroke, while ensuring that the snap ring 50a passing through the material feeding rod 20 is still stably supported by the snap ring mounting plate 40.

[0102] Reference Figure 3 As shown, in some embodiments, the detection mechanism 70 is also connected to any one or more of the following components: magnetic strip 74, pressure reducing valve, and pressure gauge 75.

[0103] The magnetic strip 74 has a displacement detection function, which can monitor the movement stroke of the detection mechanism 70 and generate accurate detection results. The magnetic strip 74 can also have an alarm function, which can sound an alarm when the movement stroke of the detection mechanism 70 exceeds the first detection position to indicate a detection result of missing or improperly installed snap ring. The detection mechanism 70 can be a cylinder. The pushing force of the detection mechanism 70 on the snap ring detection plate 77 can be adjusted by a pressure reducing valve, and the pushing force of the detection mechanism 70 on the snap ring detection plate 77 can be monitored by a pressure gauge 75, thereby achieving reasonable and effective detection.

[0104] Furthermore, the aforementioned drive mechanism 30, including the first drive device 32 and the second drive device 33, can both be cylinders to facilitate precise control of the stroke.

[0105] In some embodiments, combined with Figure 3 and Figure 4 As shown, the drive mechanism 30 includes a first drive device 32 and a second drive device 33 connected together. The detection mechanism 70 is connected to the first drive device 32, and the snap ring mounting plate 40 is connected to the second drive device 33. During the first drive stroke, the first drive device 32 drives the second drive device 33 and the snap ring mounting plate 40 from the initial state to the material distribution state, and drives the snap ring detection plate 77 to move to a third detection position that exceeds the first detection position. During the second drive stroke, the first drive device 32 first drives the second drive device 33 and the snap ring mounting plate 40 from the material distribution state to the initial state, and then the second drive device 33 drives the snap ring mounting plate 40 from the initial state to the installation state.

[0106] The detection mechanism 70 is connected to the first drive device 32. During the first drive stroke of the first drive device 32 performing the snap ring feeding, it is driven to detect whether a snap ring has been installed at the target position, so as to avoid repeated installation of the snap ring. In addition, the design of the detection mechanism 70 being connected to the first drive device 32 can also make the overall structure of the snap ring assembly mechanism stable and facilitate the arrangement of the snap ring assembly mechanism.

[0107] The front end of the snap ring detection plate 77 is positioned at a suitable distance from the first drive device 32 to ensure that the snap ring detection plate 77 does not interfere with the EPB caliper 11 during the process of the detection mechanism 70 being driven to detect whether a snap ring has been installed at the target position. That is, the third detection position can be equivalent to the second detection position, and during the process of the detection mechanism 70 being driven to detect whether a snap ring has been installed at the target position, the snap ring detection plate 77 will at most move to abut against the push rod of the EPB caliper 11.

[0108] In addition, combined Figure 3 , Figure 4 , Figure 9 and Figure 11As shown, in the embodiment where the drive mechanism 30 includes a first drive device 32 and a second drive device 33 connected together, and the detection mechanism 70 is connected to the first drive device 32, after the second drive device 33 drives the snap ring mounting plate 40 to complete the snap ring installation, it returns to its original position (i.e., drives the snap ring mounting plate 40 to move from the installed state to the initial state). On the one hand, this returns the entire drive mechanism 30 to its initial position so that the next snap ring can be installed. On the other hand, it leaves a detection space 770 between the snap ring 50b' installed at the target position and the snap ring mounting plate 40 so that a detection can be performed.

[0109] In some embodiments, refer to Figure 3 As shown, a proximity switch 26 is provided at the discharge end 22, and the feed end of the feed rod 20 is connected to the feeding device 25, which is connected to the proximity switch 26.

[0110] The feeding device 25 can be a vibratory feeder or other suitable feeding mechanism. A proximity switch 26 can detect whether a retaining ring is present at the discharge end 22. The feeding device 25, connected to the feed end of the feeding rod 20, is connected to the proximity switch 26, enabling timely feeding when the proximity switch 26 detects the absence of a retaining ring at the discharge end 22. The retaining ring 50c, fed by the feeding device 25, moves along the feeding rod 20 to the discharge end 22, ensuring the continuous progress of the retaining ring assembly process. Thus, the entire retaining ring assembly mechanism can automatically complete the entire retaining ring assembly process: feeding → distributing → installation → inspection.

[0111] This invention also provides a snap ring assembly method, applicable to the snap ring assembly mechanism described in any of the above embodiments. The features and principles of the snap ring assembly mechanism described in any of the above embodiments can be applied to the snap ring assembly method embodiments below. In the following snap ring assembly method embodiments, the features and principles of snap ring assembly already explained will not be repeated.

[0112] Figure 12 The main steps of the snap ring assembly method in an embodiment of the present invention are shown. It should be noted that the process shown in the accompanying drawings is only an illustrative example and does not necessarily include all steps; for example, some steps can be decomposed, some steps can be combined or partially combined, and the actual execution order may change according to the actual situation.

[0113] Combination Figure 3 , Figure 4 and Figure 12 As shown, the snap ring assembly method provided in this embodiment of the invention includes:

[0114] S810 controls the drive mechanism to execute the first drive stroke, causing the retaining ring inserted at the discharge end to fall off;

[0115] S820 controls the drive mechanism to execute the second drive stroke to push the fallen snap ring into the target position.

[0116] By controlling the drive mechanism 30 to execute the first drive stroke and the second drive stroke along the snap ring installation direction "x" in sequence, the snap ring can be divided using the first drive stroke and installed using the second drive stroke. On the one hand, the drive stroke of the drive mechanism 30 is always along the snap ring installation direction "x", which simplifies control. On the other hand, dividing the snap ring along the snap ring installation direction "x" can prevent the ends of the snap rings from hooking together, thereby completing the snap ring assembly efficiently and accurately.

[0117] In an embodiment where the drive mechanism 30 includes a first drive device 32 and a second drive device 33 connected together, the snap ring assembly method further includes: controlling the first drive device 32 to run during the first drive stroke; and controlling the first drive device 32 to perform a drive stroke that is opposite in direction and equal in distance to the first drive stroke during the second drive stroke, and then controlling the second drive device 33 to run during the second drive stroke.

[0118] The first drive stroke controls the first drive device 32 to operate independently. In the second drive stroke, the first drive device 32 is first controlled to return to its original position, and then the second drive device 33 is controlled to operate independently (the second drive device 33 can be controlled to return to its original position after the snap ring is installed). In this way, the snap ring can be divided and installed by controlling each drive device to execute a set of drive strokes in opposite directions and with equal distances. The control is simple and convenient, without the need for multiple strokes to be superimposed. It can also achieve two control accuracies, one coarse (first drive device 32) and one fine (second drive device 33), to ensure the accurate division and installation of the snap ring and to reserve inspection space for subsequent inspection.

[0119] In an embodiment where the snap ring assembly mechanism also includes a detection mechanism 70 that is disposed opposite to the drive mechanism 30 and connected to a snap ring detection plate 77, the snap ring assembly method further includes: after the second drive stroke is completed, controlling the detection mechanism 70 to perform a detection stroke to detect whether the snap ring at the target position is installed in place.

[0120] The detection mechanism 70 can be set up independently and is not connected to the first drive device 32. At this time, when the second drive stroke is completed, the detection mechanism 70 is controlled to execute the detection stroke, which can realize convenient detection of whether the target position is accurately equipped with a snap ring.

[0121] Furthermore, in an embodiment where the detection mechanism 70 is connected to the first driving device 32, the snap ring assembly method further includes: controlling the driving mechanism 30 to execute a first driving stroke, and also driving the detection mechanism 70 to execute a detection stroke to detect whether a snap ring is installed at the target position; and, after the second driving stroke is completed, controlling the detection mechanism 70 to execute a detection stroke to detect whether the snap ring at the target position is installed in place.

[0122] Specifically, combined Figures 3 to 11 As shown, the control process of snap ring assembly mechanism for material distribution → installation → inspection includes: In the initial state, snap ring 50a, which is inserted through material feeding rod 20, is supported by the bearing part 44 of snap ring mounting plate 40; then, the lifting mechanism 60 is controlled to lift, and the first drive device 32 is controlled to execute the first drive stroke, so that the snap ring at the end of the material discharge end 22 falls onto the EPB clamp 11; next, the first drive device 32 is controlled to execute the drive stroke opposite to the first drive stroke, so as to use snap ring mounting plate 40 to distribute snap rings and receive snap ring 50a on material feeding head, and then the second drive device 33 is controlled to continue to execute the remaining second drive stroke to push the fallen snap ring 50b into place. After the snap ring is installed, the second drive device 33 is controlled to return to its original position; then the inspection mechanism 70 is controlled to run, and the snap ring 50b' installed in the target position is back-pushed to detect whether the snap ring is missing or not assembled in place; finally, the inspection mechanism 70 retracts, and the entire snap ring assembly mechanism returns to the initial state.

[0123] Furthermore, the feeding rod 20 can be connected to the feeding device 25; thus, through the feeding of the feeding device 25, the drive mechanism 30 can automatically complete the entire snap ring assembly process of feeding → distributing → installing → inspecting. Moreover, the entire snap ring assembly mechanism has a simple structure, is easy to maintain, meets the requirements of high efficiency in modern production, and can greatly reduce production input.
