[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0027] Embodiments of this utility model provide a high-efficiency filter screen gripping device, such as... Figure 1-4 As shown, the filter includes a support 100, a first suction nozzle 210 fixed to the support 100, a magnet 310, and a pin assembly 320. The first suction nozzle 210 is positioned downwards to attract products below it. The pin assembly 320 can be attracted by the magnet 310; specifically, a portion of the pin assembly 320 can be attracted by the magnet 310, or any portion of the pin assembly 320 can be attracted by the magnet 310. The magnet 310 is located on the top surface of the filter 11, and the pin assembly 320 is located on the bottom surface of the filter 11. The pin assembly 320 and the magnet 310 attract each other and clamp the filter 11 in place. The first suction nozzle 210 is located above the filter 11 and can attract the magnet 310 and / or the pin assembly 320.

[0028] Before picking up the filter screen 11, the filter screen 11 can be placed on the pin assembly 320 by an automated production line or manually. Then, a magnet 310 is placed on the filter screen 11 at the position corresponding to the pin assembly 320. The pin assembly 320 and the magnet 310 attract each other, thereby clamping and fixing the filter screen 11. Then, the robot can drive the bracket 100 close to the filter screen 11. The first suction nozzle 210 attracts the magnet 310 and / or the pin assembly 320, thereby picking up the filter screen 11. After that, the robot can drive the filter screen 11 close to the front mold of the mold and put the filter screen 11 into the front mold for subsequent forming of the filter screen bracket 12 on the filter screen 11.

[0029] Therefore, this embodiment solves the problem that traditional suction cup fixtures cannot grasp the filter screen 11, can stably grasp the filter screen 11, realizes automated grasping, and improves the production efficiency of the product.

[0030] In some embodiments, the magnet 310 is cylindrical, which is easy to insert into the first suction nozzle 210. Specifically, it can be cylindrical, square, or other cylindrical. When gripping the filter screen 11, the magnet 310 is inserted into the first suction nozzle 210 to increase the contact area with the first suction nozzle 210, so as to more stably adsorb and fix the filter screen 11.

[0031] In some embodiments, the pin assembly 320 includes a pin 321 that can be attracted by a magnet 310 and a pad 322 sleeved on the outside of the pin 321. The pad 322 can increase the contact area with the filter screen 11, improve the clamping effect on the filter screen 11, and thus clamp and fix the filter screen 11 more securely. At the same time, the pin assembly 320 adopts a split structure of pin 321 and pad 322. The pin 321 can be made of a metal material that can be attracted by a magnet 310, while the pad 322 can be made of a lightweight material such as bakelite, so as to reduce the overall weight of the pin assembly 320 and make it easier for the first suction nozzle 210 to be attracted.

[0032] In some embodiments, the high-efficiency gripping device for the filter screen further includes a jig plate 400, which is provided with a positioning groove 410 for positioning the filter screen 11, and the bottom wall of the positioning groove 410 is provided with a receiving groove 420 for accommodating the insert assembly 320.

[0033] Before picking up the filter screen 11, first put the pin assembly 320 into the receiving groove 420, then put the filter screen 11 into the positioning groove 410, and then place the magnet 310 on the filter screen 11 at the position corresponding to the pin assembly 320. The pin assembly 320 and the magnet 310 attract each other, and then the filter screen 11 can be picked up.

[0034] In this embodiment, the jig plate 400 can position the pin assembly 320 and the filter screen 11, so that the position of the pin assembly 320 relative to the filter screen 11 remains uniform, thereby stably clamping and fixing the filter screen 11, and ensuring that the first suction nozzle 210 can accurately adsorb the magnet 310 and / or the pin assembly 320.

[0035] In some embodiments, a second suction nozzle 220 is also fixed on the bracket 100, and the second suction nozzle 220 is arranged facing upward. When the mold is opened, the second suction nozzle 220 can first pick up the product already formed on the rear mold, and then the first suction nozzle 210 puts the filter screen 11 into the front mold. This can complete the product demolding and demolding as quickly as possible, without the need for multiple actions of the robotic arm, reducing waiting time and improving work efficiency.

[0036] Furthermore, the support 100 includes a main rod 110 extending along a first direction and a plurality of connecting rods 120 connected to the main rod 110 and extending along a second direction. The connecting rods 120 are adjustable in position along the first direction. Both the first suction nozzle 210 and the second suction nozzle 220 are connected to the connecting rods 120. The first suction nozzle 210 and the second suction nozzle 220 can be connected to the same connecting rod 120, or each first suction nozzle 210 and each second suction nozzle 220 can be connected to a separate connecting rod 120. Both the first suction nozzle 210 and the second suction nozzle 220 are adjustable in position along the second direction. Both the first and second directions are parallel to the horizontal direction and perpendicular to each other.

[0037] Therefore, both the first suction nozzle 210 and the second suction nozzle 220 can move along the first direction and / or the second direction, which can adapt to different specifications of filter screens 11, thereby improving the applicability of the entire filter screen high-efficiency gripping device.

[0038] The connecting rod 120 can be directly connected to the main rod 110, or it can be indirectly connected to the main rod 110 through an intermediate structure.

[0039] In some embodiments, the bracket 100 further includes a first fixing seat 130, a second fixing seat 140, a first locking member, and a second locking member. The first fixing seat 130 is fixedly connected to the connecting rod 120, and the first locking member is used to lock the first fixing seat 130 onto the main rod 110 or to loosen the first fixing seat 130. When the first locking member loosens the first fixing seat 130, the first fixing seat 130 can move along a first direction, thereby adjusting the position of the suction nozzle in the first direction; when the first locking member locks the first fixing seat 130 onto the main rod 110, the suction nozzle can maintain the adjusted position, preventing random movement and improving stability.

[0040] The second fixed seat 140 is fixedly connected to the corresponding first suction nozzle 210 or second suction nozzle 220. The second locking member is used to lock the second fixed seat 140 onto the connecting rod 120 or to loosen the second fixed seat 140. When the second locking member loosens the second fixed seat 140, the second fixed seat 140 can move along the second direction, thereby adjusting the position of the suction nozzle in the second direction; when the second locking member locks the second fixed seat 140 onto the connecting rod 120, the suction nozzle can maintain the adjusted position, preventing random movement and improving stability.

[0041] like Figure 2As shown, both the first and second locking components include a screw and a nut fitted onto the screw. The main rod 110 has a T-slot extending in a first direction, and the connecting rod 120 has a T-slot extending in a second direction. The screw head is located in the T-slot and can slide along it, allowing the corresponding first fixing seat 130 to slide along the main rod 110 and the second fixing seat 140 to slide along the connecting rod 120. When it is necessary to tighten the first fixing seat 130 or the second fixing seat 140, the nut is tightened, causing the nut and screw head to clamp the sidewall of the T-slot, thereby locking the first fixing seat 130 onto the main rod 110, or locking the second fixing seat 140 onto the connecting rod 120.

[0042] In some embodiments, a connecting plate 160 is fixed on the main rod 110. The connecting plate 160 is used to connect with a multi-axis robot. The multi-axis robot can drive the entire filter screen's efficient gripping device to move, thereby enabling the filter screen to be placed into the front mold and the filter screen 11 with the filter screen support 12 already formed to be taken out from the rear mold.
