Description

Technical Field

[0001] The present invention is applied to the technical field of assembly equipment, and in particular relates to a parts assembly equipment. Background Art

[0002] With the development of science and technology, tablet computers have become an important tool in human life. Tablet computers have many components and require high integration. If high-precision assembly is not performed, it will directly affect the user experience. Component A and component B are important components of tablet computers. Since component A has a sticky structure, release paper is pasted on the surface of component A. Release paper is a kind of anti-stick paper that prevents prepreg from sticking and protects the prepreg from contamination. Therefore, the release paper on the surface of component A needs to be torn off and assembled with component B, and then the assembly is installed on the product. Chinese patent number CN202439329U discloses a machine for automatically tearing off release paper, which realizes automatic tearing off of release paper, but its structure is complex, maintenance is difficult, equipment cost is high, and parts assembly cannot be realized. Therefore, it is necessary to provide a parts assembly equipment with compact structure, high precision and automatic tearing off of release paper. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a parts assembly device with compact structure, high precision and automatic tearing of the mold paper.

[0004] The technical solution adopted by the present invention is as follows: the present invention comprises a machine body, on which a first feeding mechanism, a second feeding mechanism and a pressure-maintaining mechanism are arranged, the first feeding mechanism comprises a first three-axis moving module and a first mounting frame, the action end of the first three-axis moving module is sequentially provided with a rotating assembly and a first driving cylinder, the output shaft of the first driving cylinder is drivingly connected to a suction cup, the first mounting frame is provided with a second driving cylinder and a protrusion, the output shaft of the second driving cylinder is drivingly connected to a transmission block, a pair of clamping claws are arranged on the transmission block, a hook is hinged on the first mounting frame, and the middle part of the hook is connected to the The transmission block is hinged, and one end of the hook away from the hinge is located on the inner side of a pair of the clamps, and the pair of the clamps cooperate with the protrusions. The second feeding mechanism includes a second three-axis moving module and several groups of flyer feeding modules. The action end of the second three-axis moving module is provided with a third driving cylinder, and the output shaft of the third driving cylinder is connected to the suction nozzle. The pressure holding mechanism includes a second mounting frame and a first linear module group. The second mounting frame is provided with a fourth driving cylinder, and the output shaft of the fourth driving cylinder is connected to the pressure block. The action end of the first linear module is provided with several groups of positioning blocks adapted to the product.

[0005] It can be seen from the above scheme that the first loading mechanism serves as the loading mechanism for component A, and the second loading mechanism serves as the loading mechanism for component B. The first three-axis moving module and the second three-axis moving module are both XYZ-axis manipulators. The suction cup and the suction nozzle are both connected to an external vacuum source. The first three-axis moving module drives the suction cup to move to the waiting position of component A. The first driving cylinder drives the suction cup to suck component A downward. Since the bottom of component A is adhered to the release paper, the release paper needs to be torn off and then assembled with component B. The first three-axis moving module drives component A to move to On the protrusion, the release paper is exposed on the outside of the protrusion, the output shaft of the second driving cylinder is connected to the transmission block, a pair of the clamping claws are arranged on the transmission block, one end of the hook is hinged to the bottom of the first mounting frame, the middle part of the hook is hinged to the transmission block, and the other end of the hook is located on the inner side of the pair of the clamping claws. When the second driving cylinder is driven upward, due to the effect of the hinge, the end of the hook away from the hinge also moves upward, and the pair of the clamping claws clamp the release paper. When the second driving cylinder is driven downward, the end of the hook away from the hinge One end of the assembly moves downward, so that the release paper is separated from the pair of clamps, thereby realizing the tearing of the release paper. Since component B needs to be installed at the bottom of component A, the rotating component is arranged at the action end of the first three-axis moving module. The rotating component flips component A 180 degrees, and the bottom of component A faces upward. Component B is loaded on several of the flyer feeding modules. The second three-axis moving module drives the suction nozzle to move to the flyer feeding module. The third driving cylinder drives the suction nozzle to suck component B downward.

The host computer controls the control mechanism of the parts assembly equipment, which lays a foundation for improving the assembly accuracy.

[0008] A preferred solution is that the second feeding mechanism further includes a first CCD camera, the first CCD camera is arranged on the action end of the second three-axis moving module, and the first CCD camera transmits the collected digital signal to the host computer.

The first CCD camera is arranged on the action end of the second three-axis mobile module. The first CCD camera converts the optical image into a digital signal, which is used for the positioning and calibration of the second three-axis mobile module to ensure high-precision assembly.

[0013] It can be seen from the above scheme that a plurality of support frames are longitudinally arranged at the action end of the fourth linear module, and a carrier loaded with component A is placed on the support frame. When component A is loaded, the fifth linear module drives the support plate to lift the carrier and move it to the fourth mounting frame, so as to facilitate the loading of the first three-axis mobile module.

When the carrier is placed on the fourth mounting frame, several of the fifth driving cylinders drive the first clamping blocks to clamp the carrier to achieve limited fixation of the carrier.

[0016] A preferred solution is that a plurality of sixth driving cylinders are arranged in the positioning block, and the output shafts of the plurality of sixth driving cylinders are all drivingly connected to the second clamping block, and the second clamping block cooperates with the product.
