If the specific posture changes, the directional indicators will also change accordingly.

[0028] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0029] Example 1

[0030] Please refer to Figures 1-6 The automatic adsorption structure of the mesh LED face mask in this embodiment includes a fixture fixing frame 1, a side posture cylinder 2, a suction cylinder fixing plate 3, a suction cylinder 4, an air inlet connector 41, and a sensor 42.

[0031] The fixture mounting bracket 1 is used to fix the entire adsorption structure. The side-positioning cylinder 2 is fixed to the fixture mounting bracket 1 and is used to drive the movement of the suction cylinder 4. The suction cylinder fixing plate 3 is fixed to the side-positioning cylinder locking head 21 and has a first through hole. The suction cylinder 4 passes through the through hole and is fixed to the suction cylinder fixing plate 3. The air inlet connector 41 is fixedly connected to the outer side wall of the suction cylinder 4 and is used to blow air to generate suction. The sensor 42 is fixed to the suction cylinder 4 and is used to detect whether the mesh LED mask is correctly adsorbed. Specifically, the fixture fixing frame 1 includes a T-shaped structure composed of a vertical plate and a horizontal plate. The vertical plate has several connecting holes for fixing and adjusting the position, so as to connect the robotic arm and adjust the connection position. The horizontal plate has connecting holes for connecting the side posture cylinder and is fixed by screws. The horizontal plate has threaded holes that penetrate the height direction, corresponding to the connecting holes on the vertical plate. The horizontal plate is vertically connected to the vertical plate by screws through the threaded holes. One side of the horizontal plate is fixedly installed on the top of the side posture cylinder 2. The bottom of the side posture cylinder 2 is hinged with an L-shaped side posture cylinder lock head 21, which is driven by connecting with the adsorption structure. The adsorption structure consists of an upper part of a suction cylinder fixing plate 3 and a side-position cylinder locking head 21. A first through hole is provided at the lower part of the suction cylinder fixing plate 3, through which the suction cylinder 4 passes and is fixed. The suction end of the suction cylinder 4 is used to adsorb the mesh-shaped LED mask. Simultaneously, an L-shaped air inlet connector 41 is provided at the top of the suction end of the suction cylinder 4. One end of the air inlet connector 41 is connected to the air inlet chamber, and the other end is connected to an air source via an air pipe. The air inlet connector 41 allows air to enter and generates a sufficient negative pressure adsorption force at the suction end of the suction cylinder to adsorb the mesh-shaped LED mask. Furthermore, a sensor 42 for detecting the adsorption status is provided on the side of the suction cylinder 4 to ensure accurate adsorption of the LED mask.

[0032] This embodiment solves the problem in the prior art that it can only adsorb flat LED masks and cannot effectively adsorb perforated grid-shaped LED masks. By using sensor 42 for detection, the reliability of adsorption is improved, ensuring that a strong negative pressure can stably adsorb perforated grid-shaped LED masks.

[0033] Example 2

[0034] Based on Embodiment 1, this embodiment further includes a suction cup cover 43 and a buffer plate 431.

[0035] The suction cup cover 43 is fitted and fixed to the suction end of the suction cup 4, and a buffer plate 431 is attached to its top surface. The top surface of the suction cup cover 43 has a second through hole for the suction end to pass through, and a clearance groove to avoid the air inlet connector 41. Specifically, the suction cup cover 43 is square, and has a second through hole matching the size of the suction end of the suction cup 4. The top of the suction cup cover 43 has a clearance groove to accommodate the air inlet connector 41, ensuring that the suction cup cover 43 does not interfere with the connection between the suction cup 4 and the air inlet connector 41. After the suction end of the suction cup 4 is inserted into the suction cup cover 43, it is tightened and fixed with screws. The top surface of the suction cup cover 43 is attached with a buffer plate 431 of the same size and specifications. This buffer plate 431 reduces the direct pressure on the mask during the adsorption process, preventing damage to the mask due to excessive pressure. The design of the buffer plate 431 also effectively disperses the adsorption force, making the adsorption process more uniform, thereby improving adsorption efficiency and stability.

[0036] Example 3

[0037] Based on Embodiment 2, the sensor 42 in this embodiment is a reflective sensor fixed to the side of the suction cup cover 43 and / or a pressure sensor disposed on the buffer plate 431. The reflective sensor on the side of the suction cup cover 43 is used to monitor the adsorption state of the mesh LED mask in real time, and the signal is fed back to the control system to ensure precise control of the adsorption process. The pressure sensor on the buffer plate 431 judges the adsorption state by monitoring the pressure generated when the mesh LED mask is adsorbed. If the pressure is abnormal, the control system will adjust the adsorption force immediately to ensure that the mesh LED mask is not damaged due to excessive adsorption force or falls off due to insufficient adsorption force. Preferably, the reflective sensor and the pressure sensor can also be used in combination to more accurately detect the adsorption state of the LED mask and further improve the reliability of adsorption.

[0038] Example 4

[0039] The structural details of the suction cylinder 4 include the arrangement of the air inlet chamber 44, the orientation of the exhaust ports, and the location of the suction holes. All exhaust ports face the central axis of the suction cylinder 4. Specifically, the suction cylinder 4 is a variable-diameter tube structure with smaller diameters at both ends and a larger diameter in the middle. The suction cylinder 4 has an air inlet chamber 44 in the middle, and a stepped surface facing the exhaust end. Several exhaust ports are evenly distributed on the stepped surface facing the exhaust end, forming a high-speed, smooth airflow channel. Preferably, all exhaust ports face the central axis of the suction cylinder 4, thereby concentrating the airflow and creating a stronger suction force. These structural designs aim to generate greater suction force, ensuring that the LED mask can be strongly adsorbed.

[0040] Example 5

[0041] Based on Example 2, the buffer plate 431 in this example is made of foam or rubber. The foam buffer plate 431 has good elasticity and durability, is lightweight, easy to use, and easy to clean, effectively reducing maintenance costs over long-term use. The rubber buffer plate 431 also provides good cushioning, has excellent pressure resistance and wear resistance, and can adapt to various temperature environments without hardening or softening due to temperature changes, thus not affecting its adsorption performance. Through the use of the buffer plate 431 with these superior properties, not only is the stability and safety of the adsorption process ensured, but the LED mask is also protected from damage during adsorption.

[0042] Example 6

[0043] Multiple first suction holes 45 are provided on the suction end side wall of the suction cylinder 4, and multiple second suction holes 432 connected to the first suction holes 45 are provided on the suction cylinder cover 43. A third suction hole 4311 is provided on the buffer plate 431 corresponding to the position of the second suction hole 432.

[0044] The suction end of the suction cylinder 4 has a first suction hole 45 arranged around the first through hole on its side wall. The suction cylinder cover 43 has a second suction hole 432 that matches the first suction hole 45 on the suction end. The buffer plate 431 attached to the suction cylinder cover 43 has a third suction hole 4311 that matches the first suction hole 45 and the second suction hole 432, forming a suction cup shape around the first through hole. The first suction hole 45, the second suction hole 432, and the third suction hole 4311 form a three-in-one adsorption system that does not interfere with the adsorption effect. Through the progressively decreasing negative pressure zone from the first suction hole 45 on the suction end, when the third suction hole 4311 is aligned with the grid strip of the face mask, a strong adsorption force can be generated, thereby achieving an adsorption effect similar to a suction cup. On the other hand, in actual operation, multiple third suction holes 4311 ensure that they are aligned and adsorbed onto the grid of the mesh LED face mask with a high probability, forming a firm adsorption effect similar to a suction cup.

[0045] Example 7

[0046] This embodiment relates to an automatic pick-and-place device for a mesh-shaped LED face mask, including a robotic arm, an automatic adsorption structure fixed to the moving end of the robotic arm, an air pipe, a solenoid valve, and a controller. The controller is connected to a side-positioning cylinder 2, a sensor 42, and the solenoid valve to control the entire adsorption and pick-and-place process. The robotic arm, guided by the controller, can precisely move to a designated position on the LED face mask. Under the control of the controller, the automatic adsorption structure controls the airflow in the air pipe by opening and closing the solenoid valve, thereby achieving the adsorption and release of the LED face mask. The sensor 42 is used to detect the position and status of the LED face mask, ensuring the accuracy and safety of the adsorption process. The entire device is designed to automate the production process of LED face masks, improve production efficiency, and reduce errors and costs associated with manual operation.

[0047] Example 8

[0048] Building upon Example 8, this example incorporates a regulating valve on the gas pipe to control the gas inflow rate, adapting to varying adsorption requirements. This regulating valve allows the device to adjust the airflow intensity and speed based on the size and weight of the LED mask and the material properties of the adsorption surface. This not only improves adsorption accuracy but also effectively prevents damage to the LED mask due to excessive airflow. Furthermore, the regulating valve provides operators with greater operational flexibility, allowing them to adjust adsorption parameters according to actual production needs, thereby achieving optimal adsorption performance.

[0049] Example 9

[0050] Building upon Example 8, this example further includes a marking device mounted on the mobile end of the robotic arm for labeling and marking the LED face mask. During the adsorption process, the marking device on the robotic arm marks the LED face mask in real time and performs the marking operation at an appropriate location. Subsequently, the LED face mask is adsorbed by an automatic adsorption structure, and the robotic arm moves to the next process for removal and placement. This process not only improves production efficiency but also enables real-time tracking and marking on the production line through marking, ensuring product quality traceability while reducing the frequency of manual inspection and lowering labor costs.

[0051] The specific working process of the automatic pick-and-place device for the mesh LED face mask in this embodiment of the utility model is as follows: (a) the robot arm moves and the side posture cylinder 2 rotates to move the suction end of the suction cylinder 4 to the position of the LED face mask; (b) the air inlet connector 41 of the suction cylinder 4 takes in air and blows air into the blowing end inside the suction cylinder 4, thereby generating a large negative pressure at the suction end to adsorb the LED face mask onto the cushioning foam; (c) after the reflection sensor detects the LED face mask, the robot arm moves to the top of the assembly line; (d) the air inlet connector 41 of the suction cylinder 4 stops taking in air, and the LED face mask falls onto the assembly line after the adsorption stops.

[0052] The timing of the controller's actions is described in detail below:

[0053] As the robotic arm begins to move, the side-positioning cylinder 2 rotates, precisely moving the suction end of the suction cylinder 4 to the side of the vertically placed LED mask. At this point, air enters through the air inlet 41 of the suction cylinder 4. Through its internal air passage design, the gas flows towards the blowing end within the suction cylinder 4, creating a strong negative pressure area at the suction end. This negative pressure area provides sufficient suction to firmly adhere the LED mask to the cushioning foam, ensuring the mask does not detach during movement.

[0054] Then, the reflection sensor starts working, accurately sensing the position of the LED mask. Once sensor 42 confirms that the mask has been stably attached to the cushioning foam, the controller issues a command to the robotic arm to continue moving, bringing the LED mask and suction cylinder 4 together directly above the production line.

[0055] Once the robotic arm reaches the designated position, the air inlet 41 of the suction cylinder 4 stops supplying air. At this point, the negative pressure inside the suction cylinder 4 disappears, the LED mask loses its adhesive force, and then, under the influence of gravity, detaches from the suction cylinder 4 and falls smoothly onto the production line. In this way, the controller completes the control of the entire motion process, ensuring that the LED mask can be accurately and efficiently placed on the production line.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
