Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically a feeding device for irregularly shaped parts with automatic posture calibration. Background Technology

[0002] Irregularly shaped parts refer to workpieces with irregular shapes. During the feeding process, these workpieces are prone to problems such as jamming and inaccurate positioning due to their special shapes. Common feeding methods include flexible vibratory feeder feeding and robotic arm gripping feeding. Irregularly shaped parts can be clamped and fed by cameras, algorithms, and robotic arms. However, the cost of visual recognition through cameras is relatively high, and algorithms also require a certain amount of training time, which increases the overall manufacturing cost of irregularly shaped parts.

[0003] Chinese patent CN119117624A discloses a feeding device for irregularly shaped parts, including a horizontally arranged worktable. Multiple tooling seats are fixed on the top surface of the worktable near the end of the conveying mechanism. Multiple first workpieces and multiple second workpieces are arranged between the tooling seats, spaced apart. A mounting base is fixed on the front end of the worktable, and a first telescopic rod is horizontally arranged inside the mounting base. A support frame is fixed on the rear end of the first telescopic rod. An ejection mechanism is rotatably arranged on the open end of the support frame. The ejection mechanism can simultaneously eject multiple first workpieces and multiple second workpieces. The ejection mechanism includes a horizontally arranged rotating shaft, rotatably mounted on the rear end of the support frame. A motor is mounted on the outside of the support frame, and the output shaft of the motor is connected to the rotating shaft via a coupling. Multiple first push rods and multiple second push rods are fixed on the rotating shaft. The center lines of the multiple first push rods are located in a first plane, and the center lines of the multiple second push rods are located in a second plane. The first and second planes are perpendicular to each other, and the multiple first and second push rods are spaced apart.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot quickly clamp and adjust the angle of irregularly shaped parts, and then quickly eject the irregularly shaped parts for loading; it also cannot quickly position the irregularly shaped parts in the front-back and left-right directions.

The left side of the flipping support is rotatably connected to the left support via a rotating shaft. The right support is fixedly mounted on the right side of the cabinet. The rotating cylinder is fixedly mounted on the right support, and the output end of the rotating cylinder is fixedly connected to the right side of the flipping support.

[0013] Furthermore, the positioning mechanism includes a support plate and a second limiting plate, wherein the support plate is fixedly installed on the upper side of the right side bracket and the second limiting plate is fixedly installed on the front left side of the right side bracket.

[0014] Furthermore, the positioning mechanism also includes a left and right positioning component, which is mounted on the right side bracket.

[0015] Furthermore, the left and right positioning components include: a right-side cylinder and an L-shaped plate, wherein the right-side cylinder is fixedly mounted on the right-side bracket, and the L-shaped plate is fixedly mounted on the output end of the right-side cylinder.

[0016] Furthermore, the conveying mechanism includes a frame, a vibratory feeder, and a baffle plate. A square opening is provided on the right side of the cabinet, the frame is located inside the square opening, the vibratory feeder is fixedly installed on the upper side of the frame, and the baffle plate is fixedly installed on the right side wall of the output end of the vibratory feeder.

[0017] Furthermore, the conveying mechanism also includes: front and rear auxiliary components, which are mounted on the right side bracket. The front and rear auxiliary components include: a linear feeder and a feeding plate. The linear feeder is fixedly mounted on the right side bracket. The output end of the vibratory feeder is fixedly connected to the linear feeder. The feeding plate is fixedly mounted on the end of the vibratory feeder away from the linear feeder.

[0018] Furthermore, a linear module is fixedly installed on the front side of the cabinet, a drive motor is fixedly installed at the output end of the linear module, and a chuck is fixedly installed at the output end of the drive motor.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the rotation of the tilting bracket of the attitude adjustment mechanism to drive the rotation of the limiting plate. The irregular part after being positioned by the positioning mechanism is pushed to the tilting bracket position. The limiting plate limits the left side of the irregular part. The gripper cylinder is activated to clamp it, so that the vertical plate moves towards the center of the gripper cylinder. The vertical plate moves towards the center of the gripper cylinder, which drives the sliding plate to move towards the center of the gripper cylinder. The sliding plate moves towards the center of the gripper cylinder, which drives the extension plate and the anti-slip plate to move towards the center of the gripper cylinder. The extension plate and the anti-slip plate clamp the irregular part and further align the front and rear positions of the irregular part. Then, the lower cylinder output end moves upward, which drives the push rod to move upward. The push rod moves upward, which drives the irregular part, the extension plate and the anti-slip plate to move upward, so that the sliding plate slides upward on the vertical plate. The rotary cylinder output end rotates, which drives the tilting bracket to rotate forward, rotating the irregular part to the preset posture angle. This is beneficial for quickly clamping and adjusting the angle of the irregular part, and then quickly pushing out the irregular part for loading operation.

[0020] 2. The irregularly shaped parts are continuously conveyed by a vibratory feeder. Baffles are used to block some of the irregularly shaped parts, allowing only irregularly shaped parts with preset postures to be conveyed from the vibratory feeder. The linear feeder conveys the irregularly shaped parts from the output end of the vibratory feeder forward to the feeding plate, from the feeding plate to the support plate. The second limiting plate limits its front and rear positions. The right cylinder output end of the left and right positioning component moves to the left, driving the L-shaped plate to move to the left. The L-shaped plate moves to the left, pushing the irregularly shaped parts on the support plate to the left flipping plate. The first limiting plate limits the left and right directions of the irregularly shaped parts, making the left and right positions of the irregularly shaped parts standard, which is conducive to quickly positioning the front and rear and left and right positions of the irregularly shaped parts.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0037] Example 1: In some examples, please refer to Figures 1-10 An automatic posture calibration feeding device for irregularly shaped parts includes a cabinet 1, and further includes a conveying mechanism 2, a positioning mechanism 3, and a posture adjustment mechanism 4. The conveying mechanism 2 is located on the right side of the cabinet 1. The positioning mechanism 3 is installed on the cabinet 1. The posture adjustment mechanism 4 is installed on the positioning mechanism 3. The posture adjustment mechanism 4 includes a flipping bracket 41, a first limiting plate 42, a gripper cylinder 43, a lower cylinder 44, and a push rod 45. The flipping bracket 41 is located on the upper side of the cabinet 1. The first limiting plate 42 is fixedly installed on the middle side of the flipping bracket 41. Two rectangular openings 46 and one circular opening 47 are opened on the right side of the flipping bracket 41. The gripper cylinder 43 is fixedly installed on the lower left side of the flipping bracket 41. The output end of the gripper cylinder 43 is located at the position of the rectangular opening 46. The lower cylinder 44 is fixedly installed on the lower right side of the flipping bracket 41. The push rod 45 is fixedly installed on the output end of the lower cylinder 44. The end of the push rod 45 away from the lower cylinder 44 is slidably connected to the circular opening 47.

[0038] The conveying mechanism 2 is used to continuously convey irregularly shaped parts. The positioning mechanism 3 performs front-to-back positioning and alignment of the irregularly shaped parts conveyed by the conveying mechanism 2, and then performs left-to-right positioning and alignment. The attitude adjustment mechanism 4 adjusts the attitude of the irregularly shaped parts after positioning and alignment.

[0039] The attitude adjustment mechanism 4 further includes a sliding clamping assembly, which is installed at the output end of the gripper cylinder 43.

[0040] The sliding clamping assembly includes: a vertical plate 48, a sliding plate 49, an extension plate 410, an anti-slip plate 411, and a tension spring 412. The vertical plate 48 is fixedly installed at the output end of the gripper cylinder 43 and is located within a rectangular opening 46. The sliding plate 49 is slidably connected to one end of the vertical plate 48 near the center of the gripper cylinder 43. The extension plate 410 is fixedly installed on the sliding plate 49 on the front side of the output end of the gripper cylinder 43. The anti-slip plate 411 is fixedly installed on the sliding plate 49 on the rear side of the output end of the gripper cylinder 43. One end of the tension spring 412 is fixedly installed on the vertical plate 48, and the other end of the tension spring 412 is fixedly installed on the sliding plate 49. The tension spring 412 is used to assist in resetting the sliding plate 49.

[0041] The rotation of the tilting bracket 41 of the attitude adjustment mechanism 4 drives the limit plate to rotate. The irregular part positioned by the positioning mechanism 3 is pushed to the position of the tilting bracket 41. The limit plate limits the left side of the irregular part. The gripper cylinder 43 is activated to clamp it, causing the vertical plate 48 to move towards the center of the gripper cylinder 43. The movement of the vertical plate 48 towards the center of the gripper cylinder 43 drives the sliding plate 49 towards the center of the gripper cylinder 43. The movement of the sliding plate 49 towards the center of the gripper cylinder 43 drives the extension plate 410 and the anti-slip plate 411 towards the center of the gripper cylinder 43. The extension plate 410 and the anti-slip plate 411 clamp the irregular part and further align the front and rear positions of the irregular part.

[0042] Next, the output end of the lower cylinder 44 moves upward, causing the push rod 45 to move upward. The upward movement of the push rod 45 causes the irregular part, the extension plate 410 and the anti-slip plate 411 to move upward, so that the sliding plate 49 slides upward on the vertical plate 48.

[0043] The sliding clamping assembly further includes a rotating assembly, which is mounted on the cabinet 1. The rotating assembly includes a left support 413, a right support 414, and a rotating cylinder 415. The left support 413 is fixedly mounted on the left side of the cabinet 1. The left side of the flipping support 41 is rotatably connected to the left support 413 via a rotating shaft. The right support 414 is fixedly mounted on the right side of the cabinet 1. The rotating cylinder 415 is fixedly mounted on the right support 414. The output end of the rotating cylinder 415 is fixedly connected to the right side of the flipping support 41. The upper side of the right support 414 is an inclined surface to facilitate the falling of irregularly shaped parts.

[0044] The rotation of the output end of the rotary cylinder 415 of the rotating component drives the flipping bracket 41 to rotate forward, and the left bracket 413 provides stability for the rotation of the flipping bracket 41.

[0045] Example 2: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, the positioning mechanism 3 includes: a support plate 31 and a second limiting plate 32. The support plate 31 is fixedly installed on the upper side of the right side bracket 414, and the second limiting plate 32 is fixedly installed on the front left side of the right side bracket 414.

[0046] The irregularly shaped part falls onto the support plate 31, and its front and rear positions are limited by the second limiting plate 32, so that its front and rear positions are in the standard position.

[0047] The positioning mechanism 3 further includes a left and right positioning component, which is mounted on the right side bracket 414.

[0048] The left and right positioning components include: a right-side cylinder 33 and an L-shaped plate 34. The right-side cylinder 33 is fixedly mounted on the right-side bracket 414, and the L-shaped plate 34 is fixedly mounted on the output end of the right-side cylinder 33.

[0049] The irregular part falls onto the support plate 31. The output end of the right cylinder 33 of the left and right positioning component moves to the left, causing the L-shaped plate 34 to move to the left. The L-shaped plate 34 moves to the left and pushes the irregular part on the support plate 31 onto the left flip plate. The first limiting plate 42 limits the left and right directions of the irregular part, so that the left and right positions of the irregular part are in the standard position.

[0050] Example 3: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, the conveying mechanism 2 includes: a frame 21, a vibratory feeder 22, and a baffle plate 23. A square opening 24 is provided on the right side of the cabinet 1. The frame 21 is located in the square opening 24 and does not contact the cabinet 1, so as to avoid the vibration of the vibratory feeder affecting the cabinet 1. The vibratory feeder 22 is fixedly installed on the upper side of the frame 21, and the baffle plate 23 is fixedly installed on the right side wall of the output end of the vibratory feeder 22.

[0051] The vibratory feeder 22 continuously conveys irregularly shaped parts, and the baffle 23 is used to block some irregularly shaped parts, allowing only irregularly shaped parts with preset postures to be conveyed away from the vibratory feeder 22.

[0052] The conveying mechanism 2 further includes: front and rear auxiliary components, which are mounted on the right side bracket 414. The front and rear auxiliary components include: a linear feeder 25 and a feeding plate 26. The linear feeder 25 is fixedly mounted on the right side bracket 414. The output end of the vibratory feeder 22 is fixedly connected to the linear feeder 25. The feeding plate 26 is fixedly mounted on the end of the vibratory feeder 22 away from the linear feeder 25. The end of the feeding plate 26 away from the linear feeder 25 is fixedly mounted on the right side bracket 414.

[0053] The linear feeder 25 conveys the irregularly shaped parts from the output end of the vibratory feeder 22 forward to the feeding plate 26, from the feeding plate 26 to the support plate 31, and the second limiting plate 32 limits its front and rear positions.

[0054] A linear module 5 is fixedly installed on the front side of the cabinet 1. A drive motor 6 is fixedly installed at the output end of the linear module 5. A chuck 7 is fixedly installed at the output end of the drive motor 6.

[0055] The output end of the linear module 5 moves to the right, driving the drive motor 6 and chuck 7 to move to the right. The push rod 45 moves upward, pushing the irregular part to the position of the chuck 7. The chuck 7 clamps the irregular part. The output end of the linear module 5 moves to the left, driving the drive motor 6, chuck 7 and irregular part to move to the left, so that it can be moved to the processing position, waiting for drilling, chamfering and other processing operations.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
