Description

Technical Field

[0001] This invention relates to the field of clutch assembly, and more specifically to a cage spring plate assembly device and method. Background Technology

[0002] Needle roller overrunning clutches, as a key one-way transmission component, are widely used in automotive transmissions, starter motors, motorcycle transmission systems, and industrial transmission equipment. The core components of this type of clutch typically include an outer ring, an inner ring, a cage with multiple wedge slots, wedges placed in the slots, and a spring plate that provides a reset torque for each wedge. For example, patent application number 202023342080.9, entitled "Spring Plate and Its One-Way Pulley," relates to this type of needle roller overrunning clutch.

[0003] Currently, in the production of needle roller overrunning clutches (especially wedge-type clutches), assembling tiny, thin, and elastic spring plates onto the cage crossbeam is a crucial assembly process. However, traditional assembly methods present numerous significant technical challenges and limitations, severely restricting further improvements in production efficiency and product quality. Specifically:

[0004] (1) Manual assembly: It relies entirely on operators to assemble each item one by one using simple tools such as tweezers and toothpicks. The operation process is cumbersome, time-consuming and labor-intensive, with low per capita output, making it difficult to meet the needs of large-scale production, and the quality consistency is poor.

[0005] (2) Vibratory feeder assembly: The spring sheet is usually a thin and long sheet with a clamping part for clamping on the crossbeam and a spring sheet part for functioning. This asymmetrical, center of gravity off-center and easily deformable structure is very easy to hook up with each other when moving in the vibratory feeder, resulting in a high risk of damage to the parts. During vibration, it is easy to flip over or stand on its side, and cannot output in a single correct posture. In addition, the thin sheet parts are easy to stack or jam on the track, which leads to low reliability of vibratory feeding, frequent machine stop cleaning, and high manual intervention and maintenance costs.

[0006] Therefore, there is an urgent need to design a cage spring assembly device to solve the problems existing in traditional assembly. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a cage spring sheet assembly device that can efficiently, accurately and reliably assemble spring sheets onto the cage.

[0008] To solve the above-mentioned technical problems, the technical solution of the present invention is: a cage spring sheet assembly device, wherein the cage is provided with a plurality of crossbeams for clamping spring sheets along the circumferential direction, including:

[0009] A cage support rotation mechanism is used to support the cage and drive the cage to rotate intermittently so that each crossbeam arrives at the press-fitting station in sequence;

[0010] The material belt conveyor mechanism is used to intermittently convey the material belt so that the spring plates carried by the material belt arrive at the punching station in sequence;

[0011] A punching mechanism is used to punch the spring sheet located at the punching station off the strip.

[0012] The lifting and rotating mechanism includes a lifting and rotating body, at least two suction nozzle assemblies mounted on the lifting and rotating body, and a drive assembly connected to the lifting and rotating body to drive the lifting and rotating body intermittently; wherein,

[0013] During each descent of the suction nozzle assembly driven by the lifting and rotating body, one suction nozzle assembly picks up the spring sheet from the punching station, while the other suction nozzle assembly presses the spring sheet it has picked up onto the crossbeam of the retainer located at the pressing station.

[0014] Furthermore, in order to enable automatic cage loading, the cage spring plate assembly equipment also includes a cage feeding mechanism, which supplies the cage to the cage support rotation mechanism.

[0015] Further, a specific structure is provided for a cage loading mechanism that can load a cage onto a cage support rotation mechanism in a preset posture. The cage loading mechanism includes:

[0016] A feed trough, used to allow the cage to move within it;

[0017] A lifting assembly for lifting a retainer that has traveled along the feed trough to its location;

[0018] A clamping and transferring assembly is used to clamp the cage supported by the lifting assembly and transfer it to the cage support rotation mechanism; wherein,

[0019] Windows are formed between adjacent crossbeams of the cage, and the lifting assembly has a insert for inserting into the lowermost window; the width of the insert gradually increases from top to bottom to correct the attitude of the cage during insertion into the corresponding window.

[0020] Furthermore, to improve the cage's attitude accuracy, the insertion part is provided with three sections for inserting into the three lowest windows of the cage; wherein,

[0021] The cross-section of the intermediate insert, parallel to the bottom surface of the cage, is an isosceles triangle or an isosceles trapezoid.

[0022] The cross-section of the two insert parts parallel to the bottom surface of the cage is a right trapezoid with a right angle near the middle insert part.

[0023] Furthermore, a specific structure for a material conveying mechanism that ensures accurate punching by the punching mechanism is provided, the material conveying mechanism comprising:

[0024] Two support conveyor wheels are spaced apart and used to support the conveyor belt, and the punching station is located between the two support conveyor wheels;

[0025] Each of the support conveyor wheels has a corresponding pressure roller, which is used to press the material strip onto the corresponding support conveyor wheel.

[0026] To further prevent deformation of the spring sheet during the conveying process, a circumferential clearance groove is provided on the support conveyor wheel opposite the position of the spring sheet carried by the conveyor belt to avoid the spring sheet.

[0027] Further, a specific structure of a suction nozzle assembly with a buffer function is provided, the suction nozzle assembly comprising:

[0028] The main body of the suction nozzle;

[0029] A connecting tube connects to and communicates with the suction nozzle body, and is slidably mounted on the lifting and rotating body;

[0030] An elastic element, disposed between the connecting tube and the lifting rotating body, is used to undergo elastic deformation to buffer the movement of the suction nozzle body downwards and being blocked.

[0031] Furthermore, to avoid positional deviation of the pressed spring sheet, the suction nozzle assembly is provided with at least three nozzles. In each rotational gap of the lifting rotating body, one of the suction nozzle assemblies holding the spring sheet reaches the correction station located between the punching station and the pressing station.

[0032] The cage spring sheet assembly equipment also includes a correction mechanism, which is used to correct the position of the spring sheet adsorbed by the nozzle assembly when the lifting and rotating mechanism descends each time.

[0033] Furthermore, to ensure that the spring plates are securely mounted on the crossbeam, the cage spring plate assembly equipment also includes a spring plate rolling mechanism. The spring plate rolling mechanism is used to roll and press the spring plates mounted on the cage during the rotation of the cage with the spring plates mounted on it driven by the cage support rotation mechanism.

[0034] Furthermore, the spring sheet roller pressing mechanism includes:

[0035] Roller press frame;

[0036] The roller is rotatably supported on the roller frame, and its axis is parallel to the axis of the cage supported by the cage support rotation mechanism. The support portion of the cage support rotation mechanism for supporting the cage is provided with an abutment surface.

[0037] A movable drive unit, connected to the roller, is used to drive the roller to move toward the cage so that the roller abuts against the abutment surface to roll the spring sheet during the rotation of the cage.

[0038] The present invention also relates to a cage spring assembly method based on the aforementioned cage spring assembly equipment, comprising:

[0039] The cage support rotation mechanism supports the cage and drives the cage to rotate intermittently. Each rotation increases the angle between adjacent crossbeams, so that each crossbeam reaches the press-fitting station in sequence.

[0040] The material conveyor mechanism intermittently conveys the material belt, allowing the spring plate at the front of the material belt to reach the punching station;

[0041] The drive assembly drives the lifting and rotating body, causing the nozzle assembly to rotate intermittently and rise and fall during each rotation interval; wherein, during each rotation interval:

[0042] Two of the suction nozzle assemblies reach the punching station and the press-fitting station, respectively.

[0043] The suction nozzle assembly of the punching station descends with the lifting and rotating body and adsorbs the spring sheet that arrives at the punching station with the material belt. After the punching mechanism punches the spring sheet off the material belt, it drives the adsorbed spring sheet to rise with the lifting and rotating body.

[0044] As the lifting and rotating body descends, the suction nozzle assembly at the pressing station presses the adsorbed spring sheet onto the crossbeam of the retainer located at the pressing station.

[0045] After sampling the above technical solutions, the present invention has the following beneficial effects:

[0046] 1. This invention uses a conveyor belt to transport a conveyor belt carrying spring sheets, and a punching mechanism to punch the spring sheets, and a suction nozzle assembly to hold the spring sheets at the punching station, which can achieve a continuous and stable supply of spring sheets. Furthermore, before punching, the suction nozzle assembly holds the spring sheets, which can stabilize the position of the spring sheets and avoid punching deviation. On the other hand, it can ensure that the spring sheets are held by the suction nozzle assembly at the expected position and angle, thereby ensuring the smooth progress of the subsequent pressing process.

[0047] 2. This invention uses a cage support rotation mechanism to intermittently rotate the cage, and a lifting and rotating mechanism to drive the nozzle assembly to rotate and lift, thereby transferring the punched spring sheets to the pressing station and pressing them onto the crossbeam of the cage located at the pressing station. This allows for efficient, accurate, and reliable assembly of the spring sheets onto the cage. Using the cage spring sheet assembly equipment of this invention to assemble the spring sheets onto the cage can significantly improve assembly efficiency and assembly quality.

[0072] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0073] Example 1: As Figures 1 to 13 As shown, a cage spring sheet assembly device includes a cage 10 with multiple crossbeams 101 along its circumference for mounting spring sheets 20, comprising:

[0074] The cage support rotation mechanism 1 is used to support the cage 10 and drive the cage 10 to rotate intermittently so that each crossbeam 101 arrives at the press-fitting station in sequence;

[0075] The material conveyor mechanism 2 is used to intermittently convey the material belt 30 so that each spring sheet 20 carried by the material belt 30 arrives at the punching station in sequence;

[0076] The punching mechanism 3 is used to punch the spring sheet 20 located at the punching station off the strip 30;

[0077] The lifting and rotating mechanism 4 includes a lifting and rotating body 41, at least two suction nozzle assemblies 42 mounted on the lifting and rotating body 41, and a drive assembly connected to the lifting and rotating body 41 to drive the lifting and rotating body 41 to rotate intermittently; wherein,

[0078] During each descent of the lifting and rotating body 41, one of the suction nozzle assemblies 42 picks up the spring sheet 20 from the punching station, while the other suction nozzle assembly 42 presses the spring sheet 20 it has picked up onto the crossbeam 101 of the retainer 10 located at the pressing station.

[0079] Specifically, the material belt conveyor 2 is used to convey the material belt 30 carrying the spring sheet 20, and the punching mechanism 3 punches it, and the suction nozzle assembly 42 is used to adsorb it at the punching station, so as to achieve a continuous and stable supply of the spring sheet 20. In addition, before punching, the suction nozzle assembly 42 is used to hold the spring sheet 20, which can stabilize the position of the spring sheet 20 and avoid punching deviation. On the other hand, it can ensure that the spring sheet 20 is adsorbed by the suction nozzle assembly 42 at the expected position and angle, thereby ensuring the smooth progress of the subsequent pressing process.

[0080] Furthermore, in this embodiment, the retainer 10 is intermittently rotated by the retainer support rotation mechanism 1, and the suction nozzle assembly 42 is rotated and raised / lowered by the lifting rotation mechanism 4, thereby transferring the punched spring sheet 20 to the pressing station and pressing it onto the crossbeam 101 of the retainer 10 located at the pressing station. Using the retainer spring sheet assembly equipment in this embodiment to assemble the spring sheet 20 onto the retainer 10 can significantly improve assembly efficiency and assembly quality.

[0081] like Figure 13 As shown, the spring sheet 20 includes a mounting portion 201 for mounting on the crossbeam 101 and a spring portion 202 connected to the mounting portion 201 via a connecting beam 203. When the suction nozzle assembly 42 suctions the spring sheet 20, it is attached to the horizontal portion of the mounting portion 201.

[0082] like Figure 2 , Figure 3 and Figure 4As shown, the punching mechanism 3 includes a punching punch 31 and a punching die 32 that cooperate with each other. The punching die 32 is located above the strip 30 and its position is fixed. The punching punch 31 is located below and can be slidably installed. The punching punch 31 rises under the drive of the lifting drive component and cooperates with the punching die 32 to punch the spring sheet 20 off the strip 30. The lifting drive component can be a cylinder, hydraulic cylinder, electric cylinder, electric push rod, cam linkage mechanism, etc. In addition, the spring sheet 20 is connected to the strip 30 through its mounting part 201. After the suction assembly 42 of the punching station absorbs the mounting part 201 of the spring sheet 20 to be punched, the punching punch 31 moves upward and cooperates with the punching die 32 to punch at the connection between the mounting part 201 and the strip 30. (During the punching process, the punching die 32 blocks the strip 30 above, and the punching punch 31 punches from bottom to top. The suction assembly 42 and the punching punch 31 essentially clamp the horizontal part of the mounting part 201, which better avoids the spring sheet 20 from shifting position due to punching.)

[0083] The cage spring assembly method based on the cage spring assembly equipment in this embodiment includes:

[0084] The cage support rotation mechanism 1 supports the cage 10 and drives the cage 10 to rotate intermittently. Each rotation rotates the angle between adjacent crossbeams 101, so that each crossbeam 101 arrives at the press-fitting station in sequence.

[0085] The material conveyor mechanism 2 intermittently conveys the material belt 30, so that the spring plate 20 at the front of the material belt 30 reaches the punching station;

[0086] The drive assembly drives the lifting rotating body 41 to intermittently rotate the suction nozzle assembly 42 and raise and lower it during each rotation interval; wherein, during each rotation interval:

[0087] Two suction nozzle assemblies 42 reach the punching station and the pressing station, respectively;

[0088] The suction nozzle assembly 42 of the punching station descends with the lifting rotating body 41 and adsorbs the spring sheet 20 that arrives at the punching station with the material belt 30. After the punching mechanism 3 punches the spring sheet 20 off the material belt 30, it drives the adsorbed spring sheet 20 to rise with the lifting rotating body 41.

[0089] As the suction nozzle assembly 42 of the pressing station descends with the lifting rotating body 41, it presses the spring sheet 20 it adsorbs onto the crossbeam 101 of the retainer 10 located at the pressing station.

[0090] In this embodiment, preferably, as follows: Figure 1 and Figure 11As shown, the cage support rotation mechanism 1 may include a support portion 12 rotatably supported on the frame and used for insertion into the cage 10, and a motor 11 connected to the support portion 12 to drive the support portion 12 to rotate intermittently. The motor 11 and the support portion 12 may be connected by a coupling 13.

[0091] In this embodiment, preferably, as follows: Figure 1 , Figure 2 and Figure 5 As shown, the material conveying mechanism 2 may include, but is not limited to, two spaced-apart support conveying wheels 21 for supporting the conveying material belt 30, and the punching station is located between the two support conveying wheels 21.

[0092] The pressure rollers 22 correspond one-to-one with the support conveyor rollers 21. The pressure rollers 22 are used to press the material belt 30 onto the corresponding support conveyor rollers 21.

[0093] The two supporting conveyor wheels 21 can be coaxially connected to a transmission wheel 23, and a transmission belt 24 is arranged between the two transmission wheels 23. One of the transmission wheels 23 is the driving wheel and is driven to rotate, thereby realizing the synchronous rotation of the two supporting conveyor wheels 21.

[0094] With this configuration, the material belt 30 can be tensioned by the cooperation of the support conveyor wheel 21 and the pressure wheel 22, and the material belt 30 will not be displaced during the punching process, thus further avoiding punching deviation.

[0095] More preferably, such as Figure 2 and Figure 5 As shown, a circumferential clearance groove 211 is provided at the position of the support conveyor wheel 21 directly opposite the spring sheet 20 carried by the material belt 30 to avoid the spring sheet 20.

[0096] like Figure 13 As shown, the spring sheet 20 carried on the conveyor belt 30 is stamped on the conveyor belt 30. After the spring sheet 20 moves to face the support conveyor wheel 21, the spring sheet 20 is exactly located in the circumferential clearance groove 211, thereby avoiding deformation and damage of the spring sheet 20 due to the conveyor belt 30.

[0097] In this embodiment, preferably, as follows: Figure 1 and Figure 6 As shown, the suction nozzle assembly 42 includes:

[0098] Nozzle body 421;

[0099] Connecting pipe 422 connects to and communicates with nozzle body 421, and is slidably mounted on lifting rotating body 41;

[0100] An elastic element 423 is disposed between the connecting tube 422 and the lifting rotating body 41, and is used to undergo elastic deformation to buffer the movement of the suction nozzle body 421 downward and being blocked.

[0101] Specifically, the suction nozzle assembly 42 is configured with a buffering structure to avoid overpressure during the process of the suction nozzle assembly 42 descending to adsorb the spring sheet 20 and during the process of the suction nozzle assembly 42 descending to press the spring sheet 20 onto the crossbeam 101.

[0102] In a feasible structure, such as Figure 1 and Figure 6 As shown, the connecting tube 422 is movably inserted into a connecting block 424, which is fixedly connected to the lifting rotating body 41. The elastic element 423 is a spring. An abutment part 4221 is provided on the connecting tube 422 above the connecting block 424. A mating plate 425 is fixedly installed on the connecting block 424. The spring is fitted onto the connecting tube 422, with its lower end abutting against the abutment part 4221 and its upper end abutting against the mating plate 425. In its natural state, the suction nozzle body 421 falls under the action of gravity and the spring. The abutment part 4221 abuts against the connecting block 424. When the suction nozzle body 421 is subjected to an upward force, it drives the connecting tube 422 to move upward, thereby compressing the spring through the abutment part 4221. The spring is compressed, thus providing a buffering effect.

[0103] Example 2: Based on Example 1, as follows Figure 1 and Figure 7 As shown, the cage spring plate assembly equipment also includes a cage feeding mechanism 5, which is used to supply the cage 10 to the cage support rotation mechanism 1.

[0104] In this way, the cage 10 can be automatically installed, further reducing reliance on manual labor and improving efficiency.

[0105] In this embodiment, preferably, as follows: Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, the cage feeding mechanism 5 includes:

[0106] The feed trough 51 is used to allow the retainer 10 to move within it;

[0107] The lifting assembly 52 is used to lift the retainer 10 as it moves along the feed chute 51 to its location.

[0108] The clamping and transferring assembly 53 is used to clamp the cage 10 supported by the lifting assembly 52 and transfer it to the cage support rotation mechanism 1; wherein,

[0109] The lifting assembly 52 may include a lifting cylinder and a lifting member 521. The lifting member 521 is slidably mounted on a fixed member. The lifting cylinder is connected to the lifting member 521 and drives the lifting member 521 to rise and fall, thereby lifting the retainer 10. A window 102 is formed between adjacent crossbeams 101 of the retainer 10. The lifting member 521 has an insertion part 5211 for inserting into the lowermost window 102. The width of the insertion part 5211 gradually increases from top to bottom to correct the posture of the retainer 10 during the insertion into the corresponding window 102.

[0110] Specifically, after the retainer 10 rolls along the feed trough 51 to the position directly opposite the lifting assembly 52, the lifting member 521 rises. During the process of inserting its insertion part 5211 into the window 102 of the retainer 10, since the insertion part 5211 is smaller at the top and larger at the bottom, it can play a role in correcting the position and posture of the retainer 10, ensuring that after the retainer 10 lifted by the lifting assembly 52 is transferred to the retainer support rotation mechanism 1, the retainer 10 is aligned with the support part 12 of the retainer support rotation mechanism 1. The support part 12 rotates the angle between the adjacent crossbeams 101, and the next crossbeam 101 just reaches the pressing station.

[0111] like Figure 8 and Figure 9 As shown, more preferably, the insertion part 5211 is provided with three for inserting into the three lowermost windows 102 of the retainer 10; wherein,

[0112] The cross-section of the intermediate insert 5211, parallel to the bottom surface of the retainer 10, is an isosceles triangle or an isosceles trapezoid.

[0113] The cross-section of the two side inserts 5211 parallel to the bottom surface of the retainer 10 is a right trapezoid with a right angle near the middle insert 5211.

[0114] Specifically, the side of the two insert parts 5211 closest to the middle insert part 5211 is a vertical surface. On the one hand, this can better prevent the cage 10 from shifting. On the other hand, it can achieve surface positioning of the two sides of the bottom crossbeam 101 of the cage 10, thereby positioning the position and angle of the cage 10 relative to the supporting member 521 with higher precision and obtaining a more accurate expected posture.

[0115] The gripping and transfer assembly 53 may include a finger cylinder 531, a longitudinal cylinder 532, and a transverse cylinder 533. The two fingers of the finger cylinder 531 are respectively equipped with gripping parts 534. The gripper 10 is gripped or released by the finger cylinder 531. The longitudinal cylinder 532 is connected to the finger cylinder 531 and drives the finger cylinder 531 to move longitudinally. The transverse cylinder 533 is connected to the longitudinal cylinder 532 and drives the longitudinal cylinder 532 to move laterally.

[0116] A specific process for transferring the cage 10 to the cage support rotation mechanism 1 using the clamping and transfer assembly 53 is as follows: First, the finger cylinder 531 drives the clamping part 534 to clamp the cage 10; then, the longitudinal movement cylinder 532 drives the finger cylinder 531 to retract longitudinally; then, the transverse movement cylinder 533 drives the longitudinal movement cylinder 532, the finger cylinder 531, and the cage 10 to move laterally toward the cage support rotation mechanism 1. After moving into position, the longitudinal movement cylinder 532 drives the finger cylinder 531 to move longitudinally toward the cage support rotation mechanism 1, inserting the clamped cage 10 onto the support part 12.

[0117] Example 3: Based on Example 1 or Example 2, such as... Figure 1 As shown, at least three suction nozzle assemblies 42 are provided. In each rotational gap of the lifting rotating body 41, one of the suction nozzle assemblies 42 with the spring sheet 20 is brought to the correction station located between the punching station and the pressing station.

[0118] The cage spring plate assembly equipment also includes a correction mechanism 6. During each descent of the lifting and rotating mechanism 4, the correction mechanism 6 is used to correct the position of the spring plate 20 adsorbed by the suction nozzle assembly 42 that has reached the correction station.

[0119] In this way, the position of the spring plate 20 can be positioned and corrected with higher precision, further ensuring the smooth progress of the pressing process.

[0120] like Figure 10 As shown, the correction mechanism 6 includes a pneumatic four-jaw chuck 63, two first clamping blocks 61 facing each other in the width direction of the clamping portion 201 of the spring sheet 20, and two second clamping blocks 62 facing each other in the length direction of the clamping portion 201 of the spring sheet 20. The opposing sides of the two first clamping blocks 61 are provided with notches 611 for avoiding the spring sheet portion 202 of the spring sheet 20. Each pair of opposing jaws of the pneumatic four-jaw chuck 63 is connected to a first clamping block 61, and each of the other pair of opposing jaws is connected to a second clamping block 62. By the convergence of the four jaws of the pneumatic four-jaw chuck 63, the two first clamping blocks 61 and the two second clamping blocks 62 move towards each other, thereby realizing the position correction of the clamping portion 201 of the spring sheet 20 in the length and width directions, and thus realizing the position correction of the entire spring sheet 20.

[0121] exist Figure 1In the specific example shown, the lifting rotating body 41 is a disc with eight suction nozzle assemblies 42 arranged circumferentially. Each group of four suction nozzle assemblies 42 is a unit. Each group of suction nozzle assemblies 42 cooperates with a cage-supported rotating mechanism 1, a material conveying mechanism 2, a punching mechanism 3, and a correction mechanism 6. Spring plates 20 are mounted on a cage 10. That is, in the entire device, the cage-supported rotating mechanism 1, the material conveying mechanism 2, the punching mechanism 3, and the correction mechanism 6 can each be set in two sets, arranged symmetrically about the center of the disc, sharing the lifting rotating body 41, and capable of simultaneously mounting spring plates 20 on two cages 10. Each group of four suction nozzle assemblies 42 effectively frees up one workstation, allowing for the addition of corresponding detection workstations as needed, such as detecting whether spring plates 20 are present on the suction nozzle assemblies 42.

[0122] Example 4: Based on Example 1, Example 2, or Example 3, such as... Figure 1 and Figure 11 As shown, the cage spring plate assembly equipment also includes a spring plate rolling mechanism 7, which is used to roll and press the spring plate 20 that is clamped on the cage 10 during the process of the cage support rotation mechanism 1 driving the cage 10 with the spring plate 20 clamped on to rotate.

[0123] Specifically, during the rotation of the cage 10, the spring sheet 20 pressed on the cage 10 is pressed by the roller 72 to achieve secondary pressing, ensuring that the spring sheet 20 is assembled in place and improving the firmness of the assembly.

[0124] Preferably, such as Figure 1 and Figure 11 As shown, the spring sheet roller pressing mechanism 7 includes:

[0125] Roller press 73;

[0126] The roller 72 is rotatably supported on the roller frame 73, and its axial direction is parallel to the axial direction of the cage 10 supported by the cage support rotation mechanism 1. The support portion 12 of the cage support rotation mechanism 1 for supporting the cage 10 is provided with an abutment surface 121.

[0127] The movable drive 71 is connected to the roller 72 and is used to drive the roller 72 toward the cage 10 so that the roller 72 abuts against the abutment surface 121 to roll the spring sheet 20 during the rotation of the cage 10.

[0128] In this process, after the cage support rotation mechanism 1 drives the cage 10 to rotate intermittently and the suction nozzle assembly 42 of the pressing station completes the pressing of all the spring plates 20 on the cage 10, the moving drive component 71 drives the roller 72 to move toward the cage 10 until the roller 72 abuts against the abutment surface 121. The cage support rotation mechanism 1 then drives the cage 10 to rotate continuously and rapidly. During the continuous and rapid rotation of the cage 10, the roller 72 performs roller pressing on the spring plates 20 clamped to the crossbeam 101 of the cage 10. The cage support rotation mechanism 1 can drive the cage 10 to rotate continuously and rapidly one, two, three, etc., as needed, thereby achieving a corresponding number of roller pressings on each spring plate 20.

[0129] The reason for activating the spring plate rolling mechanism 7 after all the spring plates 20 on the cage 10 are installed is to avoid the support part 12 and the cage 10 supported by the support part 12 from shifting due to the compression of the abutment surface 121 by the spring plate rolling mechanism 7 during the process of pressing the spring plates 20 onto the crossbeam 101 by the suction nozzle assembly 42. In addition, this method can also achieve multiple rolling of a single spring plate 20 as needed.

[0130] The support part 12 is provided with a contact surface 121 that abuts against the roller 72. During the operation of the spring sheet roller pressing mechanism 7, the roller 72 abuts against the contact surface 121. On the one hand, this can prevent the roller 72 from over-pressing the spring sheet 20, and on the other hand, it can prevent the roller 72 from jumping during rotation.

[0131] The moving drive component 71 can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, etc., and the roller 72 can be a rubber wheel with a certain degree of elasticity.

[0132] Example 5: Figures 1 to 13 As shown, based on Embodiment 1, the cage spring sheet assembly equipment further includes, as shown in the figure, Figure 1 , Figure 7 , Figure 8 and Figure 9 The cage feeding mechanism 5 shown is as follows: Figure 10 The correction mechanism 6 shown and as follows Figure 1 and Figure 11 The spring sheet roller pressing mechanism 7 is shown. The entire working process of the equipment is as follows:

[0133] After the retainer 10 rolls along the feed trough 51 to the position directly opposite the lifting assembly 52, the lifting member 521 rises. During the insertion process of its insertion part 5211 into the window 102 of the retainer 10, the retainer 10 is corrected in posture. The clamping and transfer assembly 53 transfers the posture-corrected retainer 10 and inserts it into the support part 12 of the retainer support rotation mechanism 1. At this time, the retainer 10 is aligned with the support part 12. The retainer support rotation mechanism 1 supports the retainer 10 and drives the retainer 10 to rotate intermittently. Each rotation rotates the angle between adjacent crossbeams 101, so that each crossbeam 101 arrives at the pressing station in sequence.

[0134] The conveyor belt 2 intermittently conveys the conveyor belt 30, causing the foremost spring plate 20 on the conveyor belt 30 to reach the punching station. The drive assembly drives the lifting rotating body 41 to intermittently rotate the suction nozzle assembly 42 and raise and lower it during each rotation interval. During each rotation interval:

[0135] The three suction nozzle assemblies 42, which are arranged sequentially along the rotation direction of the lifting rotating body 41, reach the punching station, the correction station and the pressing station respectively;

[0136] The suction nozzle assembly 42 of the punching station descends with the lifting rotating body 41 and adsorbs the spring sheet 20 that arrives at the punching station with the material belt 30. After the punching mechanism 3 punches the spring sheet 20 off the material belt 30, it drives the adsorbed spring sheet 20 to rise with the lifting rotating body 41.

[0137] The nozzle assembly 42 at the correction station descends with the lifting rotating body 41, and the correction mechanism 6 positions the nozzle assembly 42 to achieve the purpose of position correction.

[0138] As the lifting rotating body 41 descends, the suction nozzle assembly 42 of the pressing station presses the spring sheet 20 it adsorbs onto the crossbeam 101 of the retainer 10 located at the pressing station.

[0139] After the nozzle assembly 42 at the press-fitting station completes the press-fitting of all the spring plates 20 of the cage 10 supported by the cage support rotation mechanism 1, the spring plate roller pressing mechanism 7 acts on the cage 10 (the moving drive 71 drives the roller pressing wheel 72 to move toward the cage 10 until the roller pressing wheel 72 abuts against the abutment surface 121). The cage support rotation mechanism 1 then drives the cage 10 to rotate continuously and rapidly for at least one revolution. The roller pressing wheel 72 of the spring plate roller pressing mechanism 7 performs roller pressing on the spring plates 20 clamped to the crossbeam 101 of the cage 10, thus strengthening the assembly between the spring plates 20 and the cage 10.

[0140] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
