Technical Field

[0001] This utility model belongs to the technical field of sealing strip production equipment, and specifically relates to an online punching system for rubber sealing strips. Background Technology

[0002] Rubber sealing strips are important automotive components. They fill gaps between body parts and provide functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. High-quality automotive sealing strips can improve driving comfort and protect the vehicle body. During the production process, rubber sealing strips require drilling holes for venting during installation. Current technology uses a drilling device to perform this drilling.

[0003] For example, patent application number CN201310264595.7 discloses an online drilling device for automotive sealing strips, comprising: a power unit; a fixing device; a drilling device that moves up and down under the drive of the power unit and drills holes in the automotive sealing strip fixed to the fixing device; and a bracket that fixes the power unit, the fixing device, and the drilling device. The drilling device includes a drilling bracket, which is fixed to a drilling guide rail on the bracket and can move up and down along the drilling guide rail. A drilling drill is fixed to the drilling bracket via a drilling drill bracket. A fine-tuning device is provided between the drilling drill and the drilling drill bracket.

[0004] For example, patent application number CN201420359525.X discloses a reciprocating online drilling device, including a base plate, a vertical plate, a sliding plate, a drive mechanism, and a drilling mechanism. The vertical plate is fixed on the base plate, and the sliding plate is slidably connected to the vertical plate. The back side of the sliding plate is slidably connected to a sliding rod fixed on the base plate through a sliding sleeve. The drive mechanism mainly consists of a motor and an eccentric linkage mechanism. The motor is connected to the eccentric linkage mechanism through a reducer, and the eccentric linkage mechanism is connected to the sliding sleeve. The drilling mechanism is fixed on the front side of the sliding plate and mainly consists of a drill and an adjustment mechanism. The drill is fixed on the adjustment mechanism.

[0005] For example, patent application number CN201920222932.9 discloses an automatic drilling machine for automotive door sealing strips, including a drilling machine housing, a drilling rig positioning sleeve, an equipment mounting frame, a return spring, a reciprocating drive rod, a frame, a reducer, a cam, a drilling rig mounting base, a drilling rig, a feeding rack, a winding rack, a control panel, and a winding motor. The equipment mounting frame is welded to one side of the top surface of the drilling machine housing. A frame is mounted on the top surface of the equipment mounting frame. A reducer is mounted at the center of the frame. A motor is located on one side of the reducer, and the motor's power output end is connected to the reducer's power input end. A cam is fitted onto the reducer's power output end. The surface of the equipment mounting frame has a through hole, and the reciprocating drive rod is inserted into the through hole. A drill mounting base is provided at the bottom of the reciprocating drive rod. The return spring is sleeved on the surface of the reciprocating drive rod, and the top of the return spring is connected to the equipment mounting frame, and the bottom of the return spring is connected to the drill mounting base. A drill positioning sleeve is welded to the lower part of the surface of the equipment mounting frame. The drill is installed at the bottom of the drill mounting base by bolts. The drill is inserted into the inside of the drill positioning sleeve. A drill hole that mates with the drill is opened at the center of the top surface of the drilling machine housing. A waste collection box that mates with the drill hole is installed on the top inner side of the drilling machine housing.

[0006] As can be seen from the above patents, existing drilling systems include a traction device and a drilling device. The drilling device includes a housing, a base inside, and a drilling structure. The base has a support seat with grooves along its front-to-back direction that mate with a rubber sealing strip. The drilling structure includes a lifting drive mechanism, a fine-tuning mechanism on the lifting drive mechanism, and a pneumatic drill on the fine-tuning mechanism. The pneumatic drill is located directly above the rubber sealing strip. The existing lifting drive mechanism is used to drive the pneumatic drill to reciprocate to achieve drilling, which requires pausing the drilling process, affecting the processing speed.

This allows the pneumatic drill to follow the rubber sealing strip backward (the speed does not need to be perfectly matched, as the rubber sealing strip can deform, and the drilled hole will also deform, so it only needs to be close; in this patent, the horizontal speed estimated by the arc will change, but it is enough to be close to the speed of the rubber sealing strip to achieve the desired effect). In addition, the various structures of this system are adjustable to adapt to more products. Attached Figure Description
