Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, specifically to an automatic assembly mechanism for door handle spring clips. Background Technology

[0002] Door handles are an indispensable part of door panels, designed to facilitate manual operation of opening and closing of doors by users. Current market handle designs exhibit diverse forms, particularly in the unique designs of the handle and panel. Meanwhile, core components such as snap rings, corner limit blocks, torsion springs, and washers tend to be standardized, serving as essential parts for door handle assembly.

[0003] As attached Figure 1 As shown, this is a retaining ring on a door handle. The retaining ring body a has a ring-shaped structure with an opening b. The end of the retaining ring body near the opening b forms an outwardly protruding retaining ring lug c. During the assembly of the door handle, the retaining ring needs to be manually or automatically installed into the designated position on the assembly fixture. Therefore, the installation process involves a certain degree of force control and precision. Improper operation may result in the retaining ring not being installed securely, or improper installation may affect the usability of the door handle.

[0004] When spring clips are assembled manually using traditional methods, there are drawbacks such as high labor costs, poor installation consistency, and poor installation quality. However, when spring clips are assembled automatically, as disclosed in Chinese Patent Publication No. CN118789271A, an automatic assembly device applicable to various door lock handles is available. (See the attached specification.) Figure 7 According to paragraphs 0078 to 0080 of its instruction manual, the snap ring feeding mechanism pushes the snap rings on the snap ring hopper one by one into the snap ring slot through the snap ring pusher plate, and then uses the snap ring finger cylinder to clamp the snap ring from the snap ring slot to the assembly fixture for pressing. This method has the following defects: (1) Since the snap rings are strung on the snap ring hopper, if there is a snap ring that is deformed, the snap ring pusher plate will not be able to push the snap ring out of the snap ring hopper, causing the snap ring automatic feeding mechanism to jam and the equipment to be unable to operate normally; (2) The snap ring is prone to angular deflection during the pushing and clamping process, which may cause the snap ring to be installed in the wrong position during the pressing process, affecting the assembly of subsequent parts of the door handle.

[0008] The present invention is further configured such that a clamping groove is provided on the circlip feeding track, the clamping groove being located on both sides of the circlip calibration position, the circlip clamping assembly including a circlip lateral movement force source, a circlip clamping transverse plate driven by the circlip lateral movement force source, a circlip vertical movement force source connected to the circlip clamping transverse plate, a circlip clamping vertical plate driven by the circlip vertical movement force source, a circlip clamping power source connected to the circlip clamping vertical plate, and a circlip clamping claw driven by the circlip clamping power source, the circlip clamping claw being adapted to the external structure of the circlip.

[0009] The present invention is further configured such that a second snap ring material detection probe is provided between the snap ring gripping claws, and when the snap ring gripping claws grip the snap ring, the second snap ring material detection probe is facing the snap ring being gripped.

[0010] The present invention is further configured to include a snap ring assembly frame, wherein the snap ring assembly frame is provided with a snap ring transverse guide rail, and the snap ring clamping transverse plate is movably connected to the snap ring transverse guide rail via a slider.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] The working principle of the automatic assembly mechanism for door handle retaining rings in this technical solution is as follows: The retaining ring vibratory feeder transports the retaining rings in a positive orientation (the retaining ring ears are basically facing the vibratory feeder) to the retaining ring feeding track. The retaining rings maintain their positive orientation and pass through the retaining ring feeding track in sequence. When a retaining ring is detected to have entered the retaining ring calibration position, the retaining ring calibration component is controlled to perform a calibration action, aligning the retaining ring in the calibration position to the target orientation. After the calibration action of the retaining ring calibration component is completed, the retaining ring clamping component is controlled to perform a retaining ring clamping and transfer action, clamping the retaining ring in the target orientation from the retaining ring calibration position onto the retaining ring guide component. After the retaining ring clamping and transfer action of the retaining ring clamping component is completed, the retaining ring pressing component is controlled to perform a retaining ring pressing action, pressing the retaining ring on the retaining ring guide component onto the assembly fixture, thus completing the automatic assembly of the retaining rings.

[0017] This utility model's automatic assembly mechanism for door handle retaining rings utilizes a retaining ring vibratory feeder and retaining ring feeding track to screen and prevent deformed retaining rings from entering the next assembly step, reducing the risk of equipment failure. The retaining rings are then sequentially placed in a positive orientation to the retaining ring calibration position. The retaining ring calibration component adjusts the retaining rings in the calibration position to the target orientation, ensuring that each retaining ring is adjusted to the target orientation before entering the assembly process. This significantly reduces installation problems caused by retaining ring angle deflection. Furthermore, the coordinated action of the retaining ring guide component and retaining ring pressing component further ensures the accuracy and reliability of the retaining rings during installation, thereby improving the installation quality and consistency of the retaining rings on the assembly fixture.

[0018] This utility model's automatic assembly mechanism for door handle spring clips automates the feeding, calibration, clamping, and pressing steps of the spring clips. The automated assembly process enables the automatic assembly mechanism for door handle spring clips to work continuously and stably, reducing labor costs. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Combined with appendix Figure 2 To be continued Figure 7 This utility model provides an automatic assembly mechanism for door handle retaining springs, comprising a retaining spring vibratory feeder 1, a retaining spring feeding track 2 connected to the vibratory feeder 1, a retaining spring calibration assembly 3 located on one side of the end of the retaining spring feeding track 2, a retaining spring clamping assembly 4 located on one side of the end of the retaining spring feeding track 2, a retaining spring guide assembly 5 located beside the retaining spring feeding track 2, and a retaining spring pressing assembly 6 located above the retaining spring guide assembly 5; the vibratory feeder 1 is used to insert the retaining spring into the door handle retaining spring in a forward-facing position. The spring feeding track 2 has a spring calibration position 27. The spring calibration component 3 is used to calibrate the spring located in the spring calibration position 27 to the target placement posture. The spring clamping component 4 is used to clamp the spring adjusted to the target placement posture onto the spring guide component 5. The spring pressing component 6 is used to press the spring on the spring guide component 5 onto the assembly tooling / product. The assembly tooling / product is not shown in the figure. The spring calibration position 27 is adapted to the spring body.

[0030] In this embodiment, the automatic assembly mechanism for door handle retaining rings works as follows: the retaining ring vibratory feeder 1 transports the retaining rings in a positive orientation (the retaining ring lugs c on the retaining ring body a are generally facing the direction of the retaining ring vibratory feeder 1) to the retaining ring feeding track 2. The retaining rings maintain their positive orientation and pass through the retaining ring feeding track 2 in sequence. When a retaining ring is detected to have entered the retaining ring calibration position 27, the retaining ring calibration component 3 is controlled to perform a calibration action, aligning the retaining rings in the retaining ring calibration position 27 to the target orientation. After the calibration action of the retaining ring calibration component 3 is completed, the retaining ring clamping component 4 is controlled to perform a retaining ring clamping and transfer action, clamping the retaining ring in the target orientation from the retaining ring calibration position 27 onto the retaining ring guide component 5. After the retaining ring clamping and transfer action of the retaining ring clamping component 4 is completed, the retaining ring pressing component 6 is controlled to perform a retaining ring pressing action, pressing the retaining rings on the retaining ring guide component 5 onto the assembly fixture / product, thus completing the automatic assembly of the retaining rings.

[0031] In this embodiment, as shown in the appendix Figure 4 and attached Figure 5 As shown, the snap ring feed track 2 has a calibration hole 21 at the position of the snap ring calibration position 27. The snap ring calibration assembly 3 includes a snap ring calibration power source 31 and a snap ring calibration claw 32 connected to the snap ring calibration power source 31. The snap ring calibration claw 32 is located in the calibration hole 21. The snap ring calibration power source 31 controls the opening and closing of the snap ring calibration claw 32.

[0032] In another embodiment, the calibration hole 21 can be an open slot; the snap ring calibration claw 32 can also be two independent push rods.

[0033] In this embodiment, since the snap ring vibratory plate 1 can only control the snap ring to enter the snap ring feed track 2 in a positive orientation, and the positive orientation angle of the snap ring is not consistent when it is conveyed in the snap ring feed track 2, when the snap ring reaches the snap ring calibration position 27, it is necessary to drive the snap ring calibration claw 32 to clamp it through the snap ring calibration power source 31. The snap ring calibration claw 32 acts on the snap ring lug c on the snap ring body a, so that the snap ring on the snap ring calibration position 27 is aligned to the target orientation. After the snap ring calibration power source 31 completes the above calibration action, it controls the snap ring calibration claw 32 to open, so that the next snap ring enters the snap ring calibration position 27 for calibration.

[0034] In this embodiment, as shown in the appendix Figure 4 and attached Figure 5As shown, a snap ring feeding detection hole 22 is provided on the snap ring feeding track 2, and a first snap ring material detection probe 23 is provided in the snap ring feeding detection hole 22. The first snap ring material detection probe 23 is directly facing the outer edge of the snap ring calibration position 27. That is, when the snap ring enters the snap ring calibration position 27, the first snap ring material detection probe 23 detects the outer edge of the snap ring body a, and the snap ring calibration power source 31 then performs the above calibration action according to the timing sequence.

[0035] In this embodiment, as shown in the appendix Figure 4 To be continued Figure 6 As shown, the retaining ring feed track 2 is provided with a clamping groove 24, which is located on both sides of the retaining ring calibration position 27. The retaining ring clamping assembly 4 includes a retaining ring horizontal movement force source 41, a retaining ring clamping horizontal movement plate 42 driven by the retaining ring horizontal movement force source 41, a retaining ring vertical movement force source 43 connected to the retaining ring clamping horizontal movement plate 42, a retaining ring clamping vertical movement plate 44 driven by the retaining ring vertical movement force source 43, and a retaining ring clamping vertical movement plate 44 connected to the retaining ring clamping vertical movement plate 42. The retaining ring clamping power source 45 on the moving plate 44 and the retaining ring clamping claw 46 driven by the retaining ring clamping power source 45 are adapted to the external structure of the retaining ring. After the retaining ring calibration power source 31 completes the above calibration action, the retaining ring in the retaining ring calibration position 27 is clamped onto the retaining ring guide assembly 5 by controlling the action of the retaining ring horizontal movement power source 41, the retaining ring vertical movement power source 43 and the retaining ring clamping power source 45.

[0036] In this embodiment, as shown in the appendix Figure 6 As shown, a second snap ring material detection probe 47 is provided between the snap ring gripping claws 46. When the snap ring gripping claws 46 grip the snap ring, the second snap ring material detection probe 47 is facing the snap ring being gripped. The second snap ring material detection probe 47 is used to detect whether the snap ring gripping claws 46 have gripped the snap ring and whether it has fallen off during the snap ring transfer process.

[0037] In this embodiment, a snap ring assembly frame 7 is also included. The snap ring assembly frame 7 is provided with a snap ring transverse guide rail 71. The snap ring clamping transverse plate 42 is movably connected to the snap ring transverse guide rail 71 via a slider.

[0038] In this embodiment, as shown in the appendix Figure 6 As shown, the snap ring pressing assembly 6 includes a snap ring pressing power source 61 connected to the snap ring clamping horizontal sliding plate 71, a snap ring pressing vertical sliding plate 62 driven by the snap ring pressing power source 61, and a snap ring pressing member 63 connected to the snap ring pressing vertical sliding plate 62.

[0039] In this embodiment, the snap ring clamping horizontal sliding plate 42 is provided with a snap ring vertical sliding guide rail 72, and the snap ring pressing vertical sliding plate 62 is connected to the snap ring vertical sliding guide rail 72 by a slider.

[0040] In this embodiment, the snap ring guide assembly 5 includes a snap ring guide power source 55, a snap ring guide fixing plate 51 driven by the snap ring guide power source 55, and a snap ring guide post 52 connected to one end of the snap ring guide fixing plate 51. A snap ring positioning part 53 is provided between the snap ring fixing plate 51 and the snap ring guide post 52. The snap ring positioning part 53 is used to position the opening b of the snap ring a. When the snap ring a is sleeved on the snap ring guide post 52, the snap ring positioning part 53 is located in the opening b of the snap ring a. The end of the snap ring guide post 52 near the snap ring pressing member 63 is frustoconical to facilitate snap ring placement. The outer periphery of the snap ring guide post 52 is provided with... The snap ring pressing member 63 is adapted to the snap ring pressing groove 54. The snap ring guide post 52 is provided with a positioning structure adapted to the assembly tooling. The specific matching method of the positioning structure is not limited. The snap ring guide power source 55 controls the lifting and lowering of the snap ring guide fixing plate 51 for connecting the snap ring guide post 52 with the assembly tooling. The snap ring guide post 52 docks with the assembly tooling / product through the positioning structure at its bottom. The snap ring pressing member 62 presses against the outer edge of the snap ring body a during the descent of the snap ring pressing vertical moving plate, so that the snap ring is assembled to the designated position. The snap ring pressing groove 54 is used to make way for the snap ring guide post 52 during the descent.

[0041] In this embodiment, the snap ring positioning part 53 may be provided with a snap ring positioning magnet 531 to further improve the positioning effect of snap ring a on the snap ring guide post 52.

[0042] In this embodiment, a snap ring feeding track 2 is provided with a snap ring feeding limit plate 25, and a snap ring feeding channel 26 is provided between the snap ring feeding track 2 and the snap ring feeding limit plate 25. The width of the snap ring feeding channel 26 is greater than the minimum outer diameter of the snap ring and less than the maximum outer diameter of the snap ring, so that the snap ring can pass through the snap ring feeding channel 26 in an orderly manner and maintain a positive placement posture.

[0043] In this embodiment, the snap ring calibration power source 31, the snap ring horizontal movement power source 41, the snap ring vertical movement power source 43, the snap ring clamping power source 45, and the snap ring pressing power source 61 can be a cylinder or a motor.

[0044] This utility model's automatic door handle snap ring assembly mechanism, through the design of the snap ring vibratory feeder 1 and snap ring feeding track 2, can to a certain extent screen and avoid deformed snap rings from entering the next assembly process, reducing the risk of equipment failure. The snap rings are then sequentially placed in a positive orientation and fed to the snap ring calibration position 27. The snap ring calibration component 3 adjusts the snap rings at the calibration position 27 to the target orientation, ensuring that each snap ring is adjusted to the target orientation before entering the assembly process. This greatly reduces the problem of improper installation caused by snap ring angle deflection. Furthermore, through the coordinated action of the snap ring guide component 5 and the snap ring pressing component 6, the accuracy and reliability of the snap rings during installation are further ensured, thereby improving the installation quality and consistency of the snap rings on the assembly fixture / product.

[0045] This utility model's automatic assembly mechanism for door handle spring clips automates the feeding, calibration, clamping, and pressing steps of the spring clips. The automated assembly process enables the automatic assembly mechanism for door handle spring clips to work continuously and stably, reducing labor costs.
