[0058] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0061] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] Referring to Figures 1 and 2 , a preferred embodiment of the present invention illustrates an automatic lid closing and flipping device 100, which includes a turntable 2, a loading device 3, a screw-locking device 4, and a unloading device 5. This automatic lid closing and flipping device 100 is used to flip a handle and then screw it in. The handle includes a grip portion and a display block disposed on the grip portion's central axis.

[0063] In order to enable the automatic lid closing and flipping attached device 100 to have a stable support platform, the turntable device 2, the loading device 3, the screw locking device 4 and the unloading device 5 are all installed on the workbench 1, so that the screw locking installation of the handle is completed on the workbench 1. The workbench 1 mainly plays a supporting role, and its specific structure is not limited here.

[0064] Referring to Figures 1 to 3 , the turntable device 2 includes a rotary drive mechanism 22 disposed on a workbench 1, a turntable 21 connected to the output shaft of the rotary drive mechanism 22, and a plurality of product carriers 23 disposed on the upper surface of the turntable 21. There is at least one product carrier 23. In a preferred embodiment, the screw locking device 4 includes a first screw locking device 41 and a second screw locking device 42 spaced apart. Four product carriers 23 are disposed on the turntable 21, distributed in a cross pattern around the turntable 21. The loading device 3, the first screw locking device 41, the second screw locking device 4, and the unloading device 5 each work in conjunction with a product carrier 23. At this time, each product carrier 23 participates in the screw locking process, and no idle product carriers 23 exist. Optionally, the number of product carriers 23 can be more than four. In this way, at the same time, only four product carriers 23 on the turntable are involved in the screw locking process, and the other product carriers 23 are in a waiting state, which has a buffering effect; optionally, the number of product carriers 23 can be less than four. In this way, one or several of the loading device 3, the first screw locking device 41, the second screw locking device 4 and the unloading device 5 may be in a waiting state, resulting in lower efficiency.

[0065] Driven by the rotary drive mechanism 22, the turntable 21 rotates, and the required working devices (loading device 3, screw locking device 4, and unloading device 5) are aligned with the product carrier 23 in the current position to perform the corresponding working operation. As the turntable 21 continues to rotate, different product carriers 23 will be brought to the working position of each working device in turn, realizing an efficient and continuous production process. The cross-shaped distribution structure of the product carriers 23 on the turntable 21 ensures that each working device can efficiently handle the corresponding handle and work without affecting other operations. This design improves production efficiency and automation, allowing the equipment to complete multiple processes simultaneously, further improving the overall efficiency of the production line.

[0066] Referring to Figure 3 , the loading device 3 includes a flipping mechanism 31, a temporary storage mechanism 32, and a feeding mechanism 33, which are spaced apart on the workbench 1 and located outside the turntable 21. The flipping mechanism 31 flips the handle and places it on the temporary storage mechanism, exposing the screw holes at the bottom of the handle. The feeding mechanism 33 then transports the handle from the temporary storage mechanism 32 to the corresponding product carrier 23.

[0067] 3 and 4 , the flipping mechanism 31 includes a first slide rail assembly 311 , a first drive motor (not shown), a flipping motor 313 , a first clamping member 314 , and a first clamping motor 315 .

[0068] The first slide rail assembly 311 includes a first slide rail 3111 disposed on the workbench 1 and located on one side of the turntable 21, and a first slider base 3112 slidably mounted on the first slide rail 3111. A first drive motor is disposed on the workbench 1, spaced apart from the first slide rail assembly 311. The first drive motor is capable of driving the first slider base 3112 to slide in a first direction (direction aa in FIG1 ), where the first direction is the extension direction of the first slide rail 3111. A flip motor 313 is disposed on the first slider base 3112. The first clamping member 314 includes a clamping arm 3141 connected to the output shaft of the flip motor 313 and a first gripper 3142 connected to the clamping arm 3141. A first gripper motor 315 is disposed on the clamping arm 3141 and is capable of driving the first gripper 3142 to open or close.

[0069] The first slide rail assembly 311 achieves precise positioning of the handle by controlling the sliding position of the first slider base 3112 and the clamping state of the first gripper 3142. By driving the first slider base 3112 to slide along the first direction, the handle can be moved to the desired position. The provision of the flip motor 313 enables the first gripper 3142 to perform a flipping action. Furthermore, by controlling the flip motor 313 to adjust the angle of the clamping arm 3142, and thereby adjust the clamping angle of the first gripper 3142, it is possible to adapt to handles of different shapes and sizes. In addition, the first gripper 3141 is controlled by the first clamping jaw motor 315 to achieve the operation of clamping or releasing the handle.

[0070] The first gripper 3142 includes a first clamping claw portion 3143 and a second clamping claw portion 3144 connected to the clamping arm 3141. The first clamping claw portion 3143 and the second clamping claw portion 3144 are opened to form a clamping space, and the robot arm of the previous station places the handle in the clamping space.

[0071] Generally speaking, the first clamping jaw 3143 and the second clamping jaw 3144 are typically configured such that the horizontal projection of the first clamping jaw 3143 is the same as the horizontal projection of the second clamping jaw 3144. That is, the first clamping jaw 3143 and the second clamping jaw 3144 are identical in length and width, and their outer end surfaces are flush. In this configuration, the first gripper 3142 grips the handle as follows: the robotic arm at the previous station adjusts the handle's position to align it with the gripping space, and then inserts the handle into the gripping space. In this process, the handle is inserted into the clamping space in mid-air. The handle must first be positioned in a space at the same height as the clamping space, and then the plugging work is completed. This method is equivalent to the alignment of space (clamping space) and space (handle positioning space). Therefore, it is bound to require the robotic arm to have high operating accuracy to ensure that the handle is accurately positioned in the space; and during the plugging process, the robotic arm is also required to have high stability to prevent movement and offset during the plugging process, which will cause the handle to be unable to be inserted into the clamping space.

[0072] As can be seen from the above description, the existing arrangement of the first clamping jaw portion 3143 and the second clamping jaw portion 3144 requires a taller robotic arm, which in turn increases production costs. However, for the handle assembly service target of this application, the company's cost-profitability is not too high. Furthermore, reducing costs by replacing manual labor with equipment is also one of the purposes of this application. Therefore, a further issue to be addressed in this application is how to reduce equipment costs.

[0073] To address the above-mentioned problem, in this embodiment, the horizontal projection length of the first clamping jaw portion 3143 is smaller than the horizontal projection length of the second clamping jaw portion 3144, and initially, the first clamping jaw portion 3143 is located above the second clamping jaw portion 3144. In this arrangement, the process of the first gripper 3142 gripping the handle is as follows: the robotic arm at the previous station positions the handle above the first gripper 3142 and then moves downward. Since the projection length of the first clamping jaw portion 3143 is smaller than the projection length of the second clamping jaw portion 3144, the arm will not collide with the first clamping jaw portion 3143. The handle continues to move downward until it contacts the second clamping jaw portion 3144, and then relies on the second clamping jaw portion 3144 to push the handle into the clamping space. In the process of this embodiment, before the handle is pushed into the clamping space, it first rests on the second clamping claw portion 3144, and then the handle is pushed into the clamping space by relying on the second clamping claw portion 3144. In this way, there is no need to use a robotic arm with high operating precision and high stability, which helps to reduce costs.

[0074] Once the handle is placed in the holding space, the robotic arm is released, and the first and second gripping jaws 3143 and 3144 close and grip the handle, completing the process of receiving the handle from the previous station. Subsequently, driven by the flip motor 313, the first gripper 3142 flips the gripping handle 180 degrees, revealing the screw hole at the bottom of the handle. Driven by the first drive motor, the gripper then moves toward the temporary storage mechanism 32, landing above it.

[0075] The temporary storage mechanism 32 includes a temporary storage base 321, a lifting component (not shown), a first positioning component 322 and a first pressure sensor 323. The temporary storage base 321 is arranged on the workbench 1 along the first direction and is spaced apart from the first slide rail 3111. The lifting component is arranged on the temporary storage base 321, and can drive the first positioning component 322 to move up and down relative to the temporary storage base 321. The lifting component can be a cylinder, a motor, etc., which is not limited here. The first positioning component 322 is arranged on the lifting component to hold the handle. The first pressure sensor 323 is arranged on the first positioning component 322 to detect the weight and position of the handle, so as to determine whether the loading is ready. Through the cooperation of the first positioning component 322 and the second pressure sensor 323, the handle can be correctly placed in the temporary storage mechanism 32, thereby improving work efficiency and accuracy.

[0076] When the handle is located above the temporary storage mechanism 32, the first positioning member 322 moves upward under the drive of the lifting component until the handle falls into the groove of the first positioning member 322. At this time, because the horizontal projection length of the first clamping claw portion 3143 is smaller than the horizontal projection length of the second clamping claw portion 3144, although the second clamping claw portion is located above the first positioning member, during the process of the first positioning member 322 rising, the first clamping claw portion 3143 does not contact the first positioning member 322, thereby avoiding interference. The first clamping claw portion 3143 and the second clamping claw portion 3144 open, releasing the handle so that the handle falls completely into the first positioning member 322, completing the temporary storage operation of the handle. Driven by the first drive motor, the flipping mechanism 31 returns to the initial position, and then, driven by the flipping motor 313, flips 180 degrees, ready for the next loading.

[0077] The feeding mechanism 33 includes a feeding base 331 , a first linear motor 332 , a first vertical base 333 , a first vertical slider 334 , a first vertical drive motor (not shown), a second gripper 336 , and a second clamping motor 337 .

[0078] Please refer to Figures 3 and 5. The feeding base 331 is arranged on the workbench 1 with a gap from the temporary storage base 321 along the first direction. The first linear motor 332 includes a first motor body 3321 installed on the top of the feeding base 331 and a second slider base 3322 slidably arranged on the first motor body 3321. In this embodiment, limit switches 3323 are provided at both ends of the first motor body 3321 to detect the position of the second slider base 3322 to ensure accurate positioning and motion control of the feeding system. The first vertical base 333 is fixed on the second slider base 3322, and the first vertical slider 334 is slidably arranged on the first vertical base 333. The first vertical drive motor is installed on the first vertical slider 334 to drive the first vertical slider 334 to slide on the first vertical base 333 in the vertical direction. The second gripper 336 is installed at the bottom of the first vertical slider 334, and the second clamping motor 337 is installed between the first vertical slider 334 and the second gripper 336 to drive the second gripper 336 to open or close, thereby clamping or releasing the handle.

[0079] In this embodiment, the second gripper 336 includes a third clamping jaw portion 3361 and a fourth clamping jaw portion 3362 installed at the bottom of the first vertical slider 334. The third clamping jaw portion 3361 is close to the temporary storage mechanism, and when the flip mechanism 31 retracts to the initial position, the second gripper 336 is clamping the handle at the same time. In one embodiment, the third clamping jaw portion 3361 is designed to be a right angle, but this setting method has the following problems: if the third clamping jaw portion 3361 is designed to be a right angle, then the second clamping jaw portion 3144 and the third clamping jaw portion 3361 will have motion interference and collide. In order to solve the above problem, in this embodiment, the third clamping jaw portion 3361 is set to be an arc shape, so that the second clamping jaw portion 3144 and the third clamping jaw portion 3361 can be effectively prevented from colliding.

[0080] Furthermore, when the third clamping portion 3361 is designed as a right angle, in order to prevent motion interference between the second clamping portion 3144 and the third clamping portion 3361, the relative distance between the third clamping portion 3361 and the fourth clamping portion 3362 in the closed state needs to be closer to each other to prevent collision with the second clamping portion 3144. Therefore, when the third clamping portion 3361 and the fourth clamping portion 3362 change from the closed state to the open state, the travel of the third clamping portion 3361 will increase accordingly. However, in this embodiment, the arc-shaped third clamping portion 3361 does not interfere with the second clamping portion 3144. Therefore, the relative distance between the third clamping portion 3361 and the fourth clamping portion 3362 in the closed state does not need to be shortened, thereby ensuring that the travel of the third clamping portion 3361 does not increase when the third clamping portion 3361 and the fourth clamping portion 3362 change from the closed state to the open state. When the stroke of the third clamping jaw portion 3361 increases, the power required by the second clamping jaw motor 337 will increase accordingly, thereby increasing the size of the second clamping jaw motor 337. Accordingly, in order to fix the second clamping jaw motor 337, the size of the feed base 331 needs to be increased. This will increase the equipment cost and does not meet the cost reduction goal of this application. Therefore, in this embodiment, the arc-shaped third clamping jaw portion 3361 is a more preferred configuration.

[0081] The arc-shaped third clamping portion 3361 also accommodates the fact that the projected length of the first clamping portion 3143 in this embodiment is shorter than the projected length of the second clamping portion 3144. The third clamping portion 3361 includes a horizontal portion (unnumbered) connected to the first vertical slider 334, an arc-shaped portion (unnumbered) connected to the horizontal portion, and a vertical portion (unnumbered) connected to the arc-shaped portion. During the retraction of the first gripper 314, the first clamping portion 3143 and the horizontal portion are positioned at the same height. When the projected length of the first clamping portion 3143 equals the projected length of the second clamping portion 3144, the first clamping portion 3143 will still interfere with the third clamping portion 3361, causing wear. However, in this embodiment, the projected length of the first clamping jaw portion 3143 is smaller than the projected length of the second clamping jaw portion 3144. At this time, since the first clamping jaw portion 3143 is shorter, the first clamping jaw portion 3143 will not interfere with the third clamping jaw portion 3361, thereby avoiding wear and collision, and correspondingly reducing the operating cost of the equipment.

[0082] Please refer to FIG6 , the screw locking device 4 includes a first screw locking device 41 and a second screw locking device 42 which are spaced apart and arranged on the workbench 1 along the circumferential direction of the turntable 21 , and are used to screw the handle.

[0083] The first screw locking device 41 includes a second slide rail assembly 411 , a second drive motor 412 , a third slide rail assembly 413 , a third drive motor 414 , an electric screwdriver slider 415 , an electric screwdriver 416 and a servo motor 417 .

[0084] The second slide rail assembly 411 includes a second slide rail 4112, mounted on the workbench 1 and located outside the turntable 21, and a second slider base 4113 slidably mounted on the second slide rail 4112. A second drive motor 412 is spaced apart from the second slide rail assembly 411 on the workbench 1 and drives the second slider base 4113 to slide on the second slide rail 4112. The third slide rail assembly 413 includes a third slide rail 4131 mounted on the second slider base 4112 and a third slider base 4132 slidably mounted on the third slide rail 4131. In this embodiment, a second pressure sensor 418 is provided at the bottom end of the third slider base 4132 to detect whether the screws are properly installed. A third drive motor 414 is mounted on the third slider base 4132 to drive the third slider base 4132 to slide on the third slide rail 4131. The movement direction of the second slider base 4113 is perpendicular to the movement direction of the third slider base 4132. The electric screwdriver block 415 is slidably mounted on the third slider base 4132, and the electric screwdriver 416 is mounted on the electric screwdriver block 415. The servo motor 417 is mounted on the third slider base 4132, driving the electric screwdriver block 415 to slide in the vertical direction, thereby driving the electric screwdriver 416 to move in the vertical direction to complete the screw locking operation.

[0085] The first screw locking device 41 can move in a second direction (bb direction in Figure 1) through the second slide rail assembly 411 and the second drive motor 412. The second direction is perpendicular to the first direction. It can move in the first direction through the third slide rail assembly 413 and the third drive motor 414, so that the position of the first screw locking device 41 on the workbench 1 can be adjusted to adapt to handles of different sizes.

[0086] The servo motor 417 can achieve precise control of the electric screwdriver slider 415, and the second pressure sensor 418 can monitor whether the screw is installed properly, thereby determining whether the current handle is defective or good.

[0087] In this embodiment, the second screw locking device 42 has a similar structure to the first screw locking device 41 , and will not be described in detail herein.

[0088] Please refer to Figure 7. The unloading device 5 includes a unloading mechanism 52 arranged between the loading device 3 and the second screw locking device 42 along the circumferential direction of the turntable 21, and a transportation mechanism 51 arranged on the workbench 1 at a distance from the unloading mechanism 52.
