Description

Technical Field

[0001] This utility model belongs to the field of vacuum suction cup technology, and in particular relates to a vacuum suction cup sealing strip pressing device. Background Technology

[0002] Vacuum suction cups, as core components in the field of automated gripping, are widely used in automotive manufacturing, electronic component assembly, glass processing, and other scenarios due to their advantages of not requiring rigid clamping and causing minimal damage to the workpiece surface. Vacuum suction cups with sealing strips, in particular, significantly improve the adhesion and sealing between the suction cup and the workpiece surface by embedding a sealing strip within the sealing groove of the suction cup body, preventing vacuum leakage and ensuring stable gripping force.

[0003] In the existing sealing strip embedding process, the operator needs to hold the strip-shaped sealing strip and align it one by one with the opening of the suction cup sealing groove, pressing the sealing strip into the groove. The assembly quality of this process is highly dependent on the operator's experience. It is necessary to keep the sealing strip pressed into the groove with uniform force. Since the sealing strip is mostly made of rubber, which has good extensibility, if the pressing force is too large, it will cause the sealing strip to shrink due to excessive deformation after being squeezed into the sealing groove, resulting in gaps in the sealing groove that are not sealed tightly. If the pressing force is too small, the sealing strip will not completely adhere to the bottom of the groove. This hidden defect will directly cause vacuum leakage in subsequent use, and in severe cases, it will cause the workpiece to fall off, resulting in equipment damage or safety accidents.

[0004] In view of the technical problems existing in the background art, this utility model provides a vacuum suction cup sealing strip pressing device.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A vacuum suction cup sealing strip pressing device includes a vacuum suction cup, a displacement mechanism and a pressing mechanism. The displacement mechanism includes a crossbar with a moving groove on it. Both sides of the moving groove have sliding grooves for the pressing mechanism to slide. The pressing mechanism includes a movable block, which is located inside the moving groove. Rollers are fixedly connected to both sides of the movable block and are in rolling connection with the sliding groove. A mounting base is rotatably connected to the bottom of the movable block, and a concave extrusion roller is rotatably connected inside the mounting base. The concave extrusion roller moves along the sliding groove to press the sealing strip.

[0006] Optionally, an adjustment box is fixedly installed at the top of the movable block, a handle is fixedly installed at the center of the top of the adjustment box, and a rotating shaft is rotatably connected at the center of the bottom of the adjustment box.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Example like Figures 1-5 As shown, a vacuum suction cup sealing strip pressing device includes a vacuum suction cup 1, a displacement mechanism 2 and a pressing mechanism 3. The displacement mechanism 2 includes a crossbar 203, on which a moving groove 210 is provided. On both sides of the moving groove 210, there are sliding grooves 211 for the pressing mechanism 3 to slide. The pressing mechanism 3 includes a movable block 301, which is disposed inside the moving groove 210. Rollers 305 are fixedly connected to both sides of the movable block 301. The rollers 305 are tumblingly connected to the sliding groove 211. A mounting base 306 is rotatably connected to the bottom end of the movable block 301. A concave pressing wheel 307 is rotatably connected inside the mounting base 306. The concave pressing wheel 307 moves along the sliding groove 211 to press the sealing strip.

[0019] Furthermore, an adjustment box 304 is fixedly installed on the top of the movable block 301, and a handle 302 is fixedly installed at the center of the top of the adjustment box 304. A rotating shaft 310 is rotatably connected at the center of the bottom of the adjustment box 304. The bottom of the rotating shaft 310 is fixedly connected to the center shaft of the top of the mounting base 306. The rotating shaft 310 inside the adjustment box 304 connects the mounting base 306 and the worm gear 308, which can transmit rotational power to drive the mounting base 306 and the concave extrusion wheel 307 to rotate, thereby realizing flexible adjustment of the angle of the concave extrusion wheel 307, which facilitates the pressing of the sealing strips arranged laterally and longitudinally on the vacuum suction cup 1.

[0020] Furthermore, a worm gear 308 is fitted onto the top outer end of the rotating shaft 310, and a worm 309 is rotatably connected inside the adjusting box 304. The worm 309 meshes with the worm gear 308, which on the one hand can change the direction of power transmission to adapt to the internal structural layout of the adjusting box 304 and facilitate the operation of the rotating wheel 303 on the outside; on the other hand, the transmission between the worm 309 and the worm gear 308 has self-locking properties, which can fix the position of the rotating shaft 310 after adjustment, prevent the concave extrusion wheel 307 from shifting due to external force, and play a limiting role for the concave extrusion wheel 307.

[0021] Furthermore, a rotating wheel 303 is rotatably connected to one side of the adjusting box 304. The central shaft of one side of the rotating wheel 303 is fixedly connected to one end of the worm 309. The rotating wheel 303 is directly connected to the worm 309. The operator can easily drive the worm 309 to mesh with the worm wheel 308 by rotating the rotating wheel 303, thereby driving the rotating shaft 310 to adjust the angle of the concave extrusion wheel 307.

[0022] Furthermore, the displacement mechanism 2 also includes a pair of movable frames 201, which are respectively disposed on both sides of the vacuum suction cup 1. A first slide rod 204 is fixedly installed inside each of the two movable frames 201. A slider 205 is slidably connected to the outer end of each first slide rod 204. The movable frames 201 of the displacement mechanism 2 provide stable support for the first slide rod 204. The slider 205 slides along the first slide rod 204, which can drive the support frame 202 and the crossbar 203 to move longitudinally, thereby adjusting the horizontal position of the pressing mechanism 3 so that the concave extrusion wheel 307 can cover different positions of the adsorption surface of the vacuum suction cup 1.

[0023] As an embodiment of this utility model, a support frame 202 is fixedly installed on the top of each slider 205. The opposing surfaces of the support frame 202 are provided with movable grooves 206. A second slide rod 207 is fixedly connected inside the movable groove 206. The movable groove 206 of the support frame 202 provides installation space for the second slide rod 207. The second slide rod 207 guides and limits the connecting block 209, ensuring that the connecting block 209 drives the crossbar 203 to move smoothly in the vertical direction. This makes it convenient for the user to squeeze the handle 302 to drive the concave extrusion wheel 307 to move down and press the sealing strip.

[0024] Furthermore, each of the outer ends of the second slide bar 207 is slidably connected to a connecting block 209. A pair of connecting blocks 209 are fixedly connected to both ends of the crossbar 203. The connecting blocks 209 connect the crossbar 203 and the second slide bar 207, so that the crossbar 203 can rise and fall along the second slide bar 207 with the connecting blocks 209. At the same time, the connecting blocks 209 are fixedly connected to the crossbar 203 to ensure that the two ends of the crossbar 203 move synchronously, avoid the crossbar 203 tilting due to uneven force, and ensure the stable operation of the pressing mechanism 3.

[0025] Furthermore, springs 208 are fitted on the outer ends of the second slide rod 207. The upper and lower ends of the springs 208 abut against the bottom end of the connecting block 209 and the bottom end of the movable groove 206, respectively. The springs 208 at the outer ends of the second slide rod 207 have an elastic reset function. When the user releases the pressure on the concave compression wheel 307, the crossbar 203 can rise again under the elastic force of the springs 208.

[0026] The working principle of this solution is as follows: During use, first place the sealing strip to be installed on the sealing groove of the suction surface of the vacuum suction cup 1. According to the sealing strip arrangement requirements, slide the slider 205 along the first slide rod 204 inside the movable frame 201, driving the support frame 202 and crossbar 203 to move longitudinally, adjusting the pressing mechanism 3 to the corresponding position above the sealing strip. Then, the operator holds the handle 302 at the upper end of the adjustment box 304 and presses it down, causing the connecting block 209 to move down along the second slide rod 207 inside the movable groove 206, compressing the spring 208 until the concave part of the concave extrusion wheel 307 adheres to the sealing strip. The outer edge of the concave extrusion wheel 307 adheres to the suction surface of the vacuum suction cup. As the concave extrusion wheel 307 rolls, the concave part of the concave extrusion wheel 307 causes the sealing strip to move evenly... The sealing strip is pressed into the sealing groove of the vacuum suction cup with uniform force. Then, the handle 302 is pushed so that the movable block 301 rolls along the slide groove 211 on the crossbar 203 via the roller 305. The concave extrusion roller 307 moves with the movable block 301 until the sealing strip is completely pressed into the sealing groove of the vacuum suction cup 1. After pressing, the handle 302 is released, and the spring 208 pushes the connecting block 209 to reset the crossbar 203 and the concave extrusion roller 307. If the sealing strip is arranged longitudinally, the rotating wheel 303 on one side of the adjusting box 304 is rotated to drive the worm gear 309 to mesh with the worm wheel 308 to rotate. The rotating shaft 310 drives the mounting base 306 and the concave extrusion roller 307 to adjust the angle, pushing the crossbar 203 and the support frame 202 to move longitudinally along the first slide bar 204 to fit the longitudinal sealing strip.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
