Description

Technical Field

[0001] The utility model relates to the field of BMV molding compound transportation devices, and specifically relates to an automatic clamping device for BMC molding compound. Background Art

[0002] Due to the inherent soft nature of BMC molding compound, some difficulties are encountered when traditional clamping devices are used to fix it. These clamping devices are often designed for clamping materials with higher hardness, and for BMC molding compound, which has certain elasticity and flexibility, their clamping effects are not ideal.

[0003] During the actual operation process, due to the special material properties of this kind of material, the existing clamping devices often cannot provide sufficient grasping force, resulting in the material may slide or even fall during the processing or transfer process. This situation not only affects the production efficiency, but also increases the production cost and risk. Therefore, in view of the special material properties of BMC molding compound, it is particularly urgent and important to develop a more suitable clamping solution. Summary of the Invention

[0004] The utility model hopes to provide an automatic clamping device for BMC molding compound, and the specific scheme is as follows:

[0005] An automatic clamping device for BMC molding compound includes a transmission platform and a clamping mechanism. The clamping mechanism includes a top plate. An installation plate is arranged below the top plate, and a driving mechanism is arranged below the installation plate. One end of the driving mechanism is provided with a connecting rod. The driving mechanism drives the connecting rod to move. One end of the connecting rod is provided with a clamping piece. A cylinder is fixedly arranged on the clamping piece. One end of the cylinder is provided with a push rod, and the other end of the push rod is connected to a rotating gripper. The rotating gripper includes a rotating shaft, a push rod fixing block and a rotating arm. The push rod fixing block is arranged in cooperation with the push rod, and the rotating arm is rotatably connected to one end of the clamping piece through the rotating shaft.

[0006] A plurality of convex blocks are arranged on the clamping piece. The convex blocks are used to increase the friction force to prevent falling.

[0007] The transmission platform includes a frame body. A transmission mechanism is arranged on the frame body. The transmission mechanism includes a first transmission member, a second transmission member and a third transmission member arranged in sequence. A plurality of first transmission rollers are arranged on the first transmission member, and second transmission rollers are arranged on the third transmission member. A transmission belt is arranged between at least one of the first transmission rollers and the second transmission rollers.

[0008] The second transmission member includes a slot. The slot can enable the clamping piece of the clamping mechanism to enter, so as to realize the clamping action (the BMC molding compound is suspended, and the rotating arm can clamp the BMC molding compound).

[0009] A baffle mechanism is provided on the third transmission member. The baffle mechanism includes a motor, and a baffle is provided at one end of the motor. The motor drives the baffle to rotate. The baffle mechanism works when it is necessary to clamp the BMC molding compound, so as to block the BMC molding compound for better grasping.

[0010] For an automatic clamping device for BMC molding compound of the present utility model, the driving mechanism can drive the connecting rod to realize the opening and collection of the clamping pieces (and thus realize clamping). After the clamping is completed, the air cylinder pushes the push rod to make the rotating gripper rotate, hold the BMC molding compound, and then transport the BMC molding compound out.
