Description

Technical Field

[0001] This application relates to the field of automobile manufacturing, and in particular to a feeding mechanism and a hood lock assembly device using the same. Background Technology

[0002] In the automotive structural system, the hood lock is a key component ensuring vehicle safety and normal operation. During the assembly of the hood lock, the feeding process of the retaining pin is extremely important, directly affecting the production efficiency and quality of the hood lock.

[0003] In existing technologies, a vibratory feeder and a robotic arm are typically used together to feed the fixing pins. The vibratory feeder sequentially transports the fixing pins to a pre-set clamping platform, and then the robotic arm transfers the fixing pins from the clamping platform to the main plate of the front hatch lock.

[0004] Since each motherboard requires two retaining pins, the industry widely adopts dual-pin clamping technology to improve production efficiency. During loading, the two retaining pins are first fed sequentially to the clamping platform. Then, specialized grippers simultaneously grasp both pins and transfer them to the motherboard, completing the synchronous installation of the two pins. However, because the vibrating feeder needs to maintain a continuous high-frequency vibration during feeding, the first retaining pin, already in place, is prone to tipping over due to the high-frequency vibration when the second pin is being fed. This significantly affects the subsequent gripping process of the grippers. Utility Model Content

[0005] One object of this application is to provide a feeding mechanism that can prevent the fixed pin from tipping over.

[0006] The feeding mechanism provided in this application adopts the following technical solution: A feeding mechanism includes a feeding component, a distributing component, and a transfer component. The feeding component has a discharge port. The distributing component includes a movably disposed distributing seat, a first driving module for driving the distributing seat to move, and at least two distributing slots formed on the distributing seat. The openings of the at least two distributing slots are arranged facing the discharge port, and the at least two distributing slots can respectively be aligned with the discharge port during the movement of the distributing seat.

[0007] By adopting the above technical solution, the multiple fixed pins output by the feeding component can be respectively accommodated in multiple distributing slots during the movement of the distributing seat. The slot walls can resist the fixed pins and prevent them from tipping over while waiting to be grabbed.

[0008] In one specific implementation, the opening direction of the discharge port is perpendicular to the moving direction of the distribution seat.

[0009] By adopting the above technical solution, it is possible to prevent the material distribution seat from getting too close to or too far from the discharge port during its movement, thus affecting the connection between the material distribution trough and the discharge port.

[0010] In one specific implementation, the at least two dispensing troughs are arranged at intervals along the moving direction of the dispensing seat.

[0011] By adopting the above technical solution, at least two material distribution troughs can pass through the discharge port in sequence during the movement of the material distribution seat, which facilitates the transfer of multiple fixing pins between the discharge port and at least two material distribution troughs.

[0012] In one specific implementation scheme, the material distribution assembly further includes at least two liftable first limiting posts and a second driving module for driving the at least two first limiting posts to rise and fall, wherein the at least two first limiting posts are respectively and correspondingly arranged in the at least two material distribution slots.

[0013] By adopting the above technical solution, the first limiting post can be inserted into the fixing pin during its upward movement and further limit the fixing pin, thereby completely solving the problem of the fixing pin tipping over.

[0014] In one specific implementation, the centerline of the first limiting post coincides with the centerline of the material distribution trough.

[0015] By adopting the above technical solution, the first limiting post can be accurately inserted into the fixing pin, preventing the fixing pin from tipping over due to relative misalignment between the first limiting post and the fixing pin when the first limiting post rises.

[0016] In one specific implementation scheme, a support plate is provided at the bottom of the material distribution trough, and a guide hole is provided through the support plate. The first limiting post is movably inserted into the guide hole along its axial direction.

[0017] By adopting the above technical solution, the guide hole can serve as a guide for the lifting and lowering of the first limiting post, preventing the first limiting post from shifting during the lifting and lowering process and affecting its limiting effect on the fixing pin.

[0018] In one specific implementation scheme, each of the dispensing troughs is provided with a first sensing module on at least one side, and a plurality of the first sensing modules are arranged along the moving direction of the dispensing seat.

[0019] By adopting the above technical solution, the first sensing module can sense the fixing pins entering the material distribution trough to ensure that each material distribution trough carries a fixing pin.

[0020] In one specific implementation, the feeding assembly includes a first feeding tray, a first feeding channel connected to the first feeding tray, and the discharge port is located at the end of the first feeding channel.

[0021] In one specific implementation, the transfer assembly includes a first robotic arm and at least two first grippers disposed on the first robotic arm, wherein the at least two first grippers correspond one-to-one with the at least two material distribution slots.

[0022] By adopting the above technical solution, at least two first grippers can simultaneously grasp the fixed pins in at least two material distribution slots, effectively improving the feeding efficiency.

[0023] Another objective of this application is to provide a front hatch lock assembly device.

[0024] The front hatch lock assembly equipment provided in this application adopts the following technical solution: A front hatch lock assembly device includes a first feeding mechanism for conveying a main board, a second feeding mechanism for transferring a bushing to the main board, and a third feeding mechanism for transferring a cover plate to the main board. The front hatch lock assembly device also includes a loading mechanism as described above for transferring a fixing pin to the main board.

[0025] By adopting the above technical solutions, the front hatch lock assembly equipment can accurately and efficiently complete the assembly of the front hatch lock, greatly improving production accuracy and efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The multiple fixing pins output by the feeding assembly can be respectively accommodated in multiple distributing slots during the movement of the distributing seat. The slot walls can resist the fixing pins to prevent them from tipping over while waiting to be grabbed. Attached Figure Description

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1: See Figure 1-2 As shown, a feeding mechanism is provided for feeding the fixing pins of the front hatch lock to solve the problem that the fixing pins are prone to tipping over when the double clamp is used.

[0034] Combination Figure 1 As shown, the feeding mechanism includes a feeding component 1, a distributing component 2, and a transfer component 3.

[0035] The feeding assembly 1 includes a first feeding plate 11, a first feeding channel 12 connected to the first feeding plate 11 and extending horizontally, and a discharge port at the end of the first feeding channel 12. The first feeding plate 11 is a vibrating feeding plate in the prior art. A first vibrating hopper 13 is disposed on the side of the first feeding plate 11. The first vibrating hopper 13 is also in the prior art. The specific feeding principles of the first feeding plate 11 and the first vibrating hopper 13 are not described in detail here.

[0036] The transfer assembly 3 includes a first robotic arm 31 and two first grippers 32 disposed on the first robotic arm 31. The two first grippers 32 correspond one-to-one with the two material dispensing slots 23. The two first grippers 32 are pneumatic fingers in the prior art.

[0037] The material distribution component 2 is positioned between the feeding component 1 and the transfer component 3. Figure 2As shown, the material distribution assembly 2 includes a material distribution seat 21 that is movably arranged in the horizontal direction, a first drive module 22 for driving the material distribution seat 21 to move, and two material distribution slots 23 opened on the material distribution seat 21. The two material distribution slots 23 are located on the side of the material distribution seat 21 close to the feeding assembly 1 and the slot openings of both are arranged facing the discharge port. The two material distribution slots 23 can be aligned with the discharge port during the movement of the material distribution seat 21.

[0038] As the feeding assembly 1 sequentially outputs the two fixed pins from the discharge port, the material distribution seat 21 can, during its movement, cause the two material distribution grooves 23 to sequentially engage with the discharge port, thereby allowing the two fixed pins to be respectively accommodated in the two material distribution grooves 23. Subsequently, the two first grippers 32 synchronously grasp the two fixed pins. In this way, while waiting to be grasped, the groove walls of the material distribution grooves 23 can resist the fixed pins, preventing them from tipping over due to the vibration of the first feeding disc 11.

[0039] In this embodiment, the opening direction of the discharge port is perpendicular to the moving direction of the material distribution seat 21, and the two material distribution grooves 23 are arranged at intervals along the moving direction of the material distribution seat 21. This prevents the material distribution seat 21 from getting too close to or too far from the discharge port during its movement, thus affecting the docking of the material distribution grooves 23 with the discharge port; furthermore, the two material distribution grooves 23 can pass through the discharge port sequentially during the movement of the material distribution seat 21, facilitating the transfer of the two fixing pins between the discharge port and the two material distribution grooves 23.

[0040] In this embodiment, the material distribution assembly 2 further includes a material distribution frame 29, and a material distribution seat 21 is slidably disposed on the top of the material distribution frame 29. The first drive module 22 is a cylinder disposed on the material distribution frame 29. A guide rail that is slidably connected to the material distribution seat 21 is also provided on the material distribution frame 29.

[0041] In this embodiment, the material distribution assembly 2 further includes two liftable first limiting posts 24 and a second driving module 25 for driving the two first limiting posts 24 to rise and fall. The two first limiting posts 24 are respectively and correspondingly arranged in the two material distribution slots 23, and the axis of the first limiting post 24 coincides with the center line of the material distribution slot 23. Here, the fixing pin is a hollow tube. After the fixing pin enters the material distribution slot 23, the first limiting post 24 can accurately insert into the fixing pin during its rising process and further limit the fixing pin, thereby completely solving the problem of the fixing pin tipping over.

[0042] Two fixing plates are also provided at the bottom of the material distribution seat 21. The two fixing plates correspond one-to-one with the two material distribution slots 23. The second drive module 25 includes two cylinders respectively set on the two fixing plates. The piston rods of the two cylinders are coaxially connected to the two first limit posts 24 respectively.

[0043] In this embodiment, a support plate 26 is provided at the bottom of the material distribution trough 23, and a guide hole 27 is provided through the support plate 26. The first limiting post 24 is movably inserted into the guide hole 27 along its axial direction. The guide hole 27 can serve as a guide for the lifting and lowering of the first limiting post 24, preventing the first limiting post 24 from shifting during the lifting and lowering process and affecting its limiting effect on the fixing pin.

[0044] In this embodiment, a first sensing module 28 is provided on both sides of each dispensing trough 23. The first sensing module 28 is a photoelectric sensor, and the four first sensing modules 28 are arranged along the moving direction of the dispensing seat 21. The first sensing modules 28 on both sides of the dispensing trough 23 can sense the fixing pins entering the dispensing trough 23 to ensure that each dispensing trough 23 carries a fixing pin.

[0045] The implementation principle of a feeding mechanism according to an embodiment of this application is as follows: The first feeding tray 11 outputs the fixing pins outward sequentially along the first feeding channel 12; The first drive module 22 drives the material distribution seat 21 to move horizontally, and the two material distribution slots 23 pass through the discharge port and receive the fixing pin in turn during the horizontal movement of the material distribution seat 21. After the fixing pin enters the material distribution groove 23, the first limiting post 24 rises and inserts into the fixing pin; Once both fixing pins are in place, the first robotic arm 31 moves the two first grippers 32 to the material distribution seat 21 and simultaneously grips the two fixing pins.

[0046] Example 2: See Figure 3-4 As shown, a front hatch lock assembly device is shown, including a base 7, on which a first feeding mechanism 4, a second feeding mechanism 5, a third feeding mechanism 6, and the loading mechanism in Embodiment 1 are provided.

[0047] The first feeding mechanism 4 is used to transport the main board of the front hatch lock. It includes two belt conveyors 41 that are parallel to each other and located in the middle of the base 7. The belt conveyors 41 are existing technology. The two belt conveyors 41 operate synchronously and their conveying directions extend along the width direction of the base 7. The two ends of the main board are supported on the two belt conveyors 41 respectively.

[0048] The second feeding mechanism 5 is used to convey the locking tongue shaft of the front hatch lock. (Combined) Figure 4As shown, the second feeding mechanism 5 includes a second feeding disc 51 located at one end of the base 7 along its length, a second feeding channel 52 connected to the second feeding disc 51 and extending horizontally, a material support 53 located on the side of the second feeding channel 52, a material support groove 54 opened on the material support 53, a second limiting post 55 that can be raised and lowered and located in the material support groove 54, and a third drive module 56 for driving the second limiting post 55 to rise and fall. The groove opening of the material support groove 54 is connected to the outlet of the second feeding channel 52. The third drive module 56 is a cylinder. A second sensing module 57 is also provided on one side of the material support groove 54. The second sensing module 57 is a photoelectric sensor.

[0049] A second gripper 58 is also provided on the first robotic arm 31. The second gripper 58 is also a pneumatic finger, which is used to grasp the locking tongue shaft after it reaches the bearing groove. The second gripper 58 and the two first grippers 32 are located on both sides of the execution end of the first robotic arm 31, and the first robotic arm 31 can grasp the fixing pin and the locking tongue shaft respectively by the first gripper 32 and the second gripper 58 during its movement stroke.

[0050] The locking tongue shaft has a hollow liquid level structure. The second feeding plate 51 conveys the locking tongue shaft towards the receiving groove 54 through the second feeding channel 52. After the locking tongue shaft is in place, the second limiting post 55 rises and inserts into the locking tongue shaft. Then the second gripper 58 grabs the locking tongue shaft and sends it to the main board.

[0051] In this embodiment, the feeding mechanism is also located at one end of the length direction of the base 7, and it and the second feeding mechanism 5 are arranged along the width direction of the base 7. The first gripper 32 can simultaneously grab the fixing pins in the two material distribution slots 23 and send them to the main board.

[0052] The third feeding mechanism 6 is located at the other end of the machine base 7 along its length. It is used to transport the cover plate of the front hatch lock. It includes a second vibrating hopper 61, a storage box 62 located on the side of the second vibrating hopper 61, and a second robotic arm 63. The second vibrating hopper 61 is existing technology. The second robotic arm 63 is equipped with a suction cup 64 and a camera 65. The second robotic arm 63 uses the suction cup 64 to pick up the cover plate and deliver it to the main board. The camera 65 is used to photograph the position of the main board to improve the assembly accuracy between the cover plate and the main board.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
