Description

Technical Field

[0001] The present invention relates to a processing device, specifically a processing device for assisting workpiece orientation. Background Art

[0002] Chinese Patent Document No. CN112109022A discloses a suction component for sucking an annular workpiece on December 22, 2020. The suction component includes: a nozzle mounting base with a hollow interior to form a vacuum generating chamber; a nozzle body with a hollow interior and an opening formed at its bottom, and a plurality of circumferentially arranged suction holes are provided around the opening; and a limiting block detachably mounted inside the nozzle body, and a forming groove for limiting the workpiece is provided on the limiting block. Wherein, a plurality of air paths are formed in the side wall of the nozzle body, and each air path leads from the corresponding suction hole to the vacuum generating chamber. When the suction component sucks the annular workpiece, the ears on the inner ring of the annular workpiece extend into the forming groove, and there is no interference between the ears and the nozzle body.

[0003] This structure is because the workpiece is provided with ears, and the nozzle body of the suction component is provided with a limiting block, and a forming groove for limiting the workpiece is provided on the limiting block. When sucking the workpiece, the workpiece is limited by the cooperation between the ears of the workpiece and the groove. If the workpiece does not have ears matching the groove, this structure has no positioning effect on the workpiece. Therefore, the range of applicable workpieces to be sucked is small and needs to be further improved.

[0004] Moreover, when the workpiece is transported to the processing position, there is no positioning of the workpiece at the processing position, and the workpiece may not accurately fall into the processing position when released. Summary of the Invention

[0005] The purpose of the present invention is to provide a processing device for assisting workpiece orientation. Through the cooperation of the material taking rod and the clamping jaw, when clamping the workpiece, the workpiece can be pre-positioned. By providing a positioning rod that moves up and down on the processing platform, before the workpiece is placed at the processing position on the processing platform, the positioning rod and the material taking rod act on the workpiece respectively to pre-position the workpiece on the processing platform, so as to overcome the deficiencies in the prior art.

[0006] A processing equipment designed for assisting workpiece orientation for this purpose includes a clamping mechanism and a processing platform. The clamping mechanism moves toward the processing platform or the material picking platform through a conveying mechanism. The clamping mechanism includes a first driver and a plurality of swinging jaws. The plurality of swinging jaws are transmission-connected to the first driver, and the plurality of swinging jaws are opened and closed by the first driver. The clamping mechanism also includes a material picking rod for sucking the workpiece, and the material picking rod is arranged between the plurality of jaws. A movable positioning rod is provided on the processing platform, and the movement directions of the material picking rod and the positioning rod are arranged opposite to each other. When the material picking rod sucks the workpiece from the material picking platform, the plurality of jaws clamp the workpiece and pre-position the workpiece on the material picking rod. When the material picking rod drives the workpiece to move to the processing platform, the material picking rod and the positioning rod act on the workpiece respectively to pre-position the workpiece on the processing platform.

[0007] After the pick-up rod absorbs the workpiece, several swinging clamps make a closing movement on the pick-up rod to clamp the workpiece, and the workpiece is pre-positioned on the pick-up rod. When the pick-up rod drives the workpiece to move to the processing platform under the action of the conveying mechanism, the positioning rod moves upward and the pick-up rod moves downward to position the workpiece up and down, so as to pre-position the workpiece on the processing platform. As the pick-up rod moves downward along the processing position of the processing platform, the positioning rod also moves downward after supporting the workpiece, and the workpiece gradually falls into the processing position. At this time, the clamps are released, and the pick-up rod also releases the workpiece, and then the clamp mechanism is reset and moves to the pick-up platform. It ensures that the workpiece falls into the processing position of the processing platform accurately. This structure makes up for the fact that the traditional clamp for sucking workpieces does not pre-position the workpiece, and also makes up for the deficiency that the workpiece is not pre-positioned after being released and placed in the processing position.

[0008] The material picking rod is arranged vertically, and the clamping mechanism also includes a movable seat that moves up and down along the material picking rod, and a plurality of clamping claws are hinged on the movable seat. The movable seat is transmission-connected to the first driver, and the first driver drives the plurality of clamping claws of the movable seat to move up and down, and the plurality of clamping claws make opening and closing movements along the material picking rod part.

[0009] The rotation force fulcrums of several clamping jaws are on the same connecting line, and the force arms of several clamping jaws are the same length. When several clamping jaws make a closing movement on the picking rod and clamp the workpiece, the workpiece is pre-positioned at the center position of the picking rod. When the picking rod absorbs the workpiece, several clamping jaws position the workpiece at the center position of the picking rod, thereby achieving the effect of automatic centering on the picking rod.

[0010] Several clamping jaws are provided with elastic connecting pieces, and several clamping jaws are connected through the elastic connecting pieces. Several clamping jaws make closing movements and elastically clamp the workpiece through the elastic connecting pieces, so as to ensure that the workpiece will not loosen during the clamping and conveying process.

[0011] A plurality of clamping jaws are provided with limiting parts, and when the plurality of clamping jaws perform opening and closing movements, the elastic connecting piece is limitedly deformed on the limiting parts.

[0012] The clamp mechanism also includes a bracket fixed on the clamp mechanism, the material picking rod part is fixed on the bracket, a linear guide is provided on the bracket, the first driver and the movable seat are respectively connected with the linear guide, and the first driver drives the movable seat to make linear movements up and down through the linear guide.

[0013] The pick-up rod picks up the workpiece by vacuum adsorption or magnetic adsorption.

[0014] The retrieving platform is provided with a retrieving position for placing the workpiece.

[0015] An adjusting piece is provided on the material picking position, and the adjusting piece is rotated up and down on the material picking position. By rotating the adjusting piece, the telescopic position of the workpiece on the material picking position is changed. According to the height of the workpiece, the telescopic position of the workpiece on the material picking position is appropriately adjusted by rotating the adjusting piece to adjust the distance at which the material picking rod absorbs the workpiece.

[0016] A processing position corresponding to the workpiece is arranged on the processing platform, and a second driver is arranged on one side of the processing platform. The second driver is transmission-connected with the positioning rod, and the positioning rod is extended and retracted up and down on the processing position through the second driver.

[0017] The effective technical effects of the present invention are as follows:

[0018] After the pick-up rod absorbs the workpiece, several swinging clamps make a closing movement on the pick-up rod to clamp the workpiece, and the workpiece is pre-positioned on the pick-up rod. When the pick-up rod drives the workpiece to move to the processing platform under the action of the conveying mechanism, the positioning rod moves upward and the pick-up rod moves downward to position the workpiece up and down, so as to pre-position the workpiece on the processing platform. As the pick-up rod moves downward along the processing position of the processing platform, the positioning rod also moves downward after supporting the workpiece, and the workpiece gradually falls into the processing position. At this time, the clamps are released, and the pick-up rod also releases the workpiece, and then the clamp mechanism is reset and moves to the pick-up platform. It ensures that the workpiece falls into the processing position of the processing platform accurately. This structure makes up for the fact that the traditional clamp for sucking workpieces does not pre-position the workpiece, and also makes up for the deficiency that the workpiece is not pre-positioned after being released and placed in the processing position.

[0019] The rotation force fulcrums of several clamping jaws are on the same connecting line, and the force arms of several clamping jaws are the same length. When several clamping jaws make a closing movement on the picking rod and clamp the workpiece, the workpiece is pre-positioned at the center position of the picking rod. When the picking rod absorbs the workpiece, several clamping jaws position the workpiece at the center position of the picking rod, thereby achieving the effect of automatic centering on the picking rod.

[0020] A regulating member is provided at the material taking position. The regulating member is rotatably arranged up and down at the material taking position. By rotating the regulating member, the telescopic position of the workpiece at the material taking position is changed. According to the height of the workpiece, by rotating the regulating member, the telescopic position of the workpiece at the material taking position is appropriately adjusted to adjust the distance for the material taking rod to suck the workpiece.

[0039] In this embodiment, the elastic connecting member 11 is annular, and the annular elastic connecting member 11 connects a plurality of clamping jaws 4 in a bundled manner. When the plurality of clamping jaws 4 are in the opening and closing motion, the elastic connecting member 11 is deformed.

[0040] A limiting part 4.1 is provided on several clamping jaws 4. When the several clamping jaws 4 make opening and closing movements, the elastic connecting piece 11 is limited and deformed on the limiting part 4.1.

[0041] In this embodiment, the annular elastic connecting piece 11 is limited and installed on the limiting part 4.1. The limiting part 4.1 is a limiting arc groove or a limiting square groove, etc.

[0045] In this embodiment, before the several clamping jaws 4 suck the workpiece 7 with the material taking rod 6, the several clamping jaws 4 are located at the upper part of the part of the material taking rod 6 (as Figure 1 shown). When the material taking rod 6 sucks the workpiece 7, the several clamping jaws 4 follow the downward movement of the movable seat 10. The several clamping jaws 4 close along the material taking rod 6 to clamp the workpiece 7. The workpiece 7 is pre-positioned on the material taking rod 6 before moving to the processing platform 3.

[0046] The material taking rod 6 sucks the workpiece 7 through vacuum adsorption or magnet adsorption.

[0047] In this embodiment, the inside of the material taking rod 6 is of a hollow structure. The material taking rod 6 is connected to a vacuum pump through a pipeline to vacuum-adsorb the workpiece 7. Or, a magnet is provided at one end of the material taking rod 6, and the workpiece 7 is sucked through magnet adsorption. The material taking rod 6 preferably vacuum-adsorbs the workpiece 7.

[0048] A material taking position 12.1 for placing the workpiece 7 is provided on the material taking platform 12.

[0049] See Figures 4 - 7 , in this embodiment, a material distributor 16 fixedly arranged on the equipment is provided on the material taking platform 12. A pushing cylinder 17 is provided on one side of the material taking platform 12.

[0052] When the vibrating plate on the equipment conveys the workpiece 7 to the distributor 16 through the feeding trough, the pushing cylinder 17 pushes the material collecting platform 12 to reciprocate along the distributor 16. When the material collecting hole is aligned with the material collecting position 12.1, the workpiece 7 naturally falls onto the material collecting position 12.1.

[0053] In this embodiment, a sensor for detecting the incoming workpiece 7 is provided on the material distributor 16. When the sensor detects the workpiece 7, the push cylinder 17 moves.

When the material picking rod 6 and the positioning rod 8 form contact with the workpiece 7 respectively, the positioning rod 8 moves downward and the material picking rod 6 moves downward. The workpiece 7 gradually descends under the action of the material picking rod 6 and the positioning rod 8, and is accurately inserted into the through hole of the other workpiece. The clamp 4 moves upward to release the workpiece 7, and the vacuum pump connected to the material picking rod 6 is turned off. The workpiece 7 falls completely into the through hole of the other workpiece under the action of gravity. Then the processing mechanism on the equipment welds and assembles the workpiece 7 with the other workpiece.
