Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spare parts production, especially relates to a stacked dust shield automatic feeding mechanism. BACKGROUND

[0002] The tire dust shield is a protective component installed behind the automobile tire, mainly used for blocking the splashing mud, dust and gravel in the driving process, to avoid its direct impact on the vehicle body or into the mechanical structure. In the dust shield manufacturing process, a grabbing mechanism is usually used to send the stacked dust shields on the frame one by one to the processing equipment to realize the automatic feeding of the dust shield.

[0003] However, the traditional automobile tire dust shield grabbing mechanism has accumulated error due to the reciprocating motion of the horizontal sliding cylinder and the slide rail in continuous operation, resulting in the misalignment of the suction cup and the product height. Especially in the case of multi-layer stacking, the error superposition will cause the collision between the mechanism and the product, causing the workpiece deformation or equipment damage. SUMMARY

[0004] Therefore, in order to solve the above problems, the utility model provides a stacked dust shield automatic feeding mechanism, which comprises:

[0005] A grabbing module is used to grab or release the product.

[0006] A lifting module is used to drive the grabbing module to move vertically and linearly.

[0007] An installation part is used to install the lifting module.

[0008] A horizontal moving module is used to drive the installation part to move horizontally and linearly.

[0009] The lifting module comprises:

[0010] A connecting rod is fixedly connected with the grabbing module.

[0011] A linear actuator is fixedly installed on the installation part. The telescopic rod of the linear actuator penetrates through the end of the connecting rod and keeps relative sliding with the connecting rod. A limiting part is arranged at the end of the telescopic rod.

[0012] A guide rod is fixedly connected with the grabbing module at one end and extends vertically upward and penetrates through the installation part at the other end. The guide rod keeps relative sliding with the installation part. An elastic member is arranged between the top end of the guide rod and the penetrated part of the installation part, and the elastic member is sleeved on the guide rod.

[0013] The utility model discloses a linear drive drives the lower movement of the limiting portion, and the connecting rod falls to the limiting portion automatically under the action of gravity, and the linear drive drives the upper movement of the limiting portion, and the limiting portion drives the upper movement of the connecting rod simultaneously, thereby realizing the control of the up-down height of the grabbing module. The movement of the grabbing module is guided through the guide rod, and the rotation movement of the cylinder can be prevented. The elastic member is arranged on the guide rod, and the elastic member is compressed during the vertical sliding of the grabbing module, so that the buffering and limiting effects are achieved, and the collision with the product can be prevented. The layer height can be adapted according to the operation process.

[0014] Further, the grabbing module comprises:

[0015] A fixed disc is connected with the connecting rod and the guide rod.

[0016] A vacuum chuck is arranged on the fixed disc.

[0017] Further, the grabbing module further comprises a second buffering device, which is fixedly installed on the fixed disc.

[0018] When the product is adsorbed, the second buffering device contacts the product first, the vacuum chuck contacts the product after buffering the impact, the vacuum chuck is loosened after sucking and fixing the product and moving to the corresponding position, and the product is moved. The impact between the vacuum chuck and the product is avoided, and the product is prevented from being damaged.

[0019] Further, the horizontal movement module comprises:

[0020] A power device;

[0021] A sliding seat is driven by the power device to move horizontally, and the mounting portion is fixedly installed on the sliding seat.

[0022] Further, the horizontal movement module further comprises two groups of limiting sensors arranged on the movement path of the sliding seat, and the sliding seat moves linearly between the two groups of limiting sensors.

[0023] Further, the horizontal movement module further comprises two groups of first buffering devices arranged on the movement path of the sliding seat, and the sliding seat moves linearly between the two groups of first buffering devices.

[0024] The sliding seat is driven by the power device to move horizontally, and when the limiting sensor senses that the sliding movement is moved to the preset maximum stroke range, a signal is sent to the controller, so that the controller controls the power device to stop working. The buffer is arranged at the horizontal two ends, and the sliding seat can be limited, buffered and prevented from colliding.

[0025] The utility model has the following advantages:

[0026] When the limiting part is driven by the linear driver to move downward, the connecting rod automatically falls to the limiting part due to gravity, and when the limiting part is driven by the linear driver to move upward, the connecting rod is simultaneously driven by the limiting part to move upward, so as to realize the control of the up-down height of the grabbing module. The movement of the grabbing module is guided by the guide rod, so as to prevent the rotation movement of the cylinder. Since the elastic member is arranged on the guide rod, the elastic member is compressed in the process of the vertical downward sliding of the grabbing module, so as to play a buffering and limiting role, and further prevent the collision of the product. The layer height can be self-adapted according to the operation process. BRIEF DESCRIPTION OF DRAWINGS
