Description

Manipulators for stand-alone conveying equipment

technical field

The utility model relates to the technical field of metal forming processing equipment, in particular to a manipulator for independent transmission equipment.

Background technique

Sheet metal stamping processing has high production efficiency, less material waste, and can improve the internal structure and mechanical properties of the workpiece material. It is a part forming process with less and no cutting. It is an extremely important processing method in many machinery manufacturing industries. However, in the current domestic press loading, unloading or the transfer of workpieces between press production lines is mostly done by manual operation, which has low production efficiency, poor working environment, and production safety cannot be guaranteed.

In this regard, a variety of independent manipulator feeding equipment has appeared on the market, and some of the manipulator claws use a vacuum suction cup type clamping method for picking and transporting. Generally, when the manipulator leaves the factory, its grasping specification or size has been fixed, but in practical applications, the same manipulator feeding equipment needs to transport plates of different specifications or sizes, so it is necessary to replace the manipulator of the corresponding specification or size to meet the normal requirements. The clamping requirements, the replacement work is cumbersome, and the applicability is not wide.

Contents of the invention

The technical problem to be solved by the utility model is to provide a manipulator for independent conveying equipment with simple structure and convenient adjustment of the specification or size of conveying boards.

In order to solve the above technical problems, the utility model adopts the following technical solutions: a manipulator for independent conveying equipment, including a mounting base plate and at least three vacuum suction cups, and at least three adjustable arms, the adjustable arm is also equipped with a mounting hole, the mounting substrate is connected with the inner end of the adjustable arm, the vacuum suction cup is connected with a buffer assembly, and the buffer assembly is connected with the outer end of the adjustable arm.

Wherein, the buffer assembly includes a connecting sleeve, a buffer pin passing through the connecting sleeve, and a spring sheathed on the buffer pin, the vacuum suction cup is fixedly connected to the lower end of the buffer pin, and the two ends of the spring are respectively connected to the connecting sleeve and the vacuum suction cup. abutting, the connecting sleeve is fixed through the nut after passing through the installation hole.

Preferably, the installation hole is a long hole.

In another preferred embodiment, the number of the mounting holes is multiple, and the multiple mounting holes are arranged at intervals on the adjustable arm.

Wherein, the inner end of the adjustable arm is hinged to the installation base plate through bolts.

Wherein, the installation substrate is in the shape of a strip, and four adjustable arms are respectively hinged at two ends of the installation substrate.

The beneficial effect of the utility model is that: the utility model provides a manipulator for independent conveying equipment. When the manipulator is in contact with the plate, the vacuum sucker uses the effect of vacuum air suction to hold the plate on the manipulator, and the manipulator and the plate When the parts are in contact, if the collision is too strong, it is easy to damage the vacuum suction cup or the plate, and affect the service life of the transfer equipment. The role of the board. When the specification or size of the plate to be transported changes, the distribution position of the vacuum suction cup can be adjusted by pulling the installation angle of the adjustable arm on the installation base plate, so that the distribution position is adapted to the specification or size of the plate, so that the manipulator Clamping and transporting boards of new specifications or sizes, the adjustment work is simple, convenient, fast and practical.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model.

As shown in Figures 1 to 3, it is an embodiment one of a manipulator for a stand-alone conveying device of the present invention. An adjustable arm 3, the adjustable arm 3 is also provided with a mounting hole 7, the mounting substrate 1 is connected to the inner end of the adjustable arm 3, the vacuum chuck 2 is connected to a buffer assembly, and the buffer assembly is connected to the adjustable arm 3 Outer connection.

When the manipulator is in contact with the plate, the vacuum chuck 2 uses the effect of vacuum suction to hold the plate on the manipulator. When the manipulator contacts the plate, if the collision is too strong, it is easy to damage the vacuum chuck 2 or the plate and affect the transfer. The service life of the equipment, the setting of the buffer component can effectively reduce the impact generated when the mechanical claw contacts the plate, and play a role in protecting the vacuum chuck 2 and the plate.

When the specification or size of the plate to be transported changes, the distribution position of the vacuum suction cup 2 can be adjusted by pulling the installation angle of the adjustable arm 3 on the installation base plate 1, so that the distribution position is adapted to the specification or size of the plate, In order to facilitate the manipulator to clamp and transport the plates of new specifications or sizes, the adjustment work is simple, convenient, fast and practical.

In this embodiment, the buffer assembly includes a connecting sleeve 4, a buffer pin 5 passing through the connecting sleeve 4, and a spring 6 sleeved on the buffer pin 5, the vacuum chuck 2 is fixedly connected to the lower end of the buffer pin 5, and the spring The two ends of 6 abut against the connecting sleeve 4 and the vacuum suction cup 2 respectively, and the connecting sleeve 4 passes through the mounting hole 7 and is fixed by nuts.

When the vacuum chuck 2 and the board are pressed against each other, the buffer pin 5 compresses the spring 6 and then slides upward, thereby effectively avoiding strong collision between the vacuum chuck 2 and the board, thereby realizing the buffering function of the buffer assembly.

As shown in Fig. 3, in this embodiment, the mounting hole 7 is a long hole, and the connecting sleeve 4 can be fixed at any position in the long hole, so that the size of the clamping plate of the manipulator can be adjusted more conveniently, and its adjustment range wider.

In this embodiment, the inner end of the adjustable arm 3 is hinged to the installation substrate 1 through a bolt, and the adjustable arm 3 can be freely moved after the bolt is loosened, and the installation angle of the adjustable arm 3 on the installation substrate 1 After the adjustment, the bolts are tightened to prevent the adjustable arm 3 from rotating by itself and affecting the normal clamping of the manipulator.

In this embodiment, the installation substrate 1 is in the shape of a long strip, and four adjustable arms 3 are respectively hinged at both ends of the installation substrate 1, and the distribution positions of the eight vacuum suction cups 2 can be adjusted arbitrarily, and the clamping stability is more stable. High, wider adjustable range, more practical.

As shown in Figure 4, it is a second embodiment of a manipulator for independent conveying equipment of the present invention. The difference from the first embodiment is that the number of the mounting holes 7 is multiple, and the multiple mounting holes 7 Set at intervals on the adjustable arm 3, it is used to adjust the connecting sleeve 4 at several specified positions on the adjustable arm 3, so as to correspond to standard parts of different sizes, so as to facilitate direct selection and adapt to the size of the plate The installation hole 7 is installed, avoiding step-by-step debugging, and the adjustment process is more convenient.

The above-mentioned embodiment is a preferred implementation of the utility model. In addition, the utility model can also be realized in other ways. Any obvious replacement is within the scope of protection of the utility model without departing from the concept of the technical solution. Inside.
