Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to equipment for producing glass products, and specifically relates to a clamping mechanism for clamping glassware. Background Art

[0002] When producing glass cups and other utensils, it is generally necessary to heat the glass with a flame. For example, when producing glass cups, the glass cup body and the handle need to be heated at the same time in the handle welding process so that their welding points reach a softened molten state, and then the cup body and the handle are brought close to each other and the molten points are in contact, so that they are connected as a whole. However, when the cup body and the handle are heated with a flame, due to the large range of the flame, when the welding point reaches a molten state, not only the welding point is heated, but also other parts of the cup body and the handle are heated to a very high temperature. At the same time, the manipulator or fixture holding the cup body and the handle will also be heated, which is an inevitable phenomenon for smaller cup bodies and handles. Therefore, when welding smaller cup bodies and handles, the temperature of the fixture or manipulator holding them is also very high. If the cup handle or cup body is manually placed in the fixture, the human hand needs to withstand the high temperature baking of the fixture; when placing the cup handle or cup body into the fixture or manipulator, the human hand may also touch the manipulator or fixture, resulting in a scalding accident.

[0003] In the patent document with application number CN106219953B, a glass cup body and handle connecting device is provided. The patent combines traditional handmade glass cups with machinery, and uses a cup body fixing device and a cup handle fixing device to realize the fixation and alignment adjustment of the cup body and the cup handle. The connecting plate of the cup handle fixing device can be fastened by bolts and nuts to adjust the height of the cross bar (including the clip thereon) fixed on the connecting plate, so that the cup handle is adjusted to a suitable position, and then the two end points of the cup handle and the two corresponding points of the cup body are heated and melted by four oxyacetylene flame guns of the hot melt device, and then the movable cup handle fixing device is pushed toward the cup body fixing device for connection and forming.

[0004] When the above patent is in use, the cup handle needs to be manually fixed on the cup handle fixing device, and the flame generated by the oxyacetylene flame gun when heating will directly heat the cup handle fixing device. Therefore, the temperature of the cup handle fixing device of this patent will increase after long-term use, and when a person places the cup handle on the cup handle fixing device, he will be burned. Utility Model Content

[0005] In order to solve the problem of scalding when fixing cup handles in the prior art, the utility model provides a clamping mechanism for producing glassware, which can conveniently clamp parts of the glassware, prevent workers from being scalded, and improve production efficiency.

[0006] The technical solution adopted by the clamping mechanism for producing glassware in the utility model is:

[0007] A clamping mechanism for producing glassware includes a movable manipulator for clamping glassware parts. Several manipulators are installed on a rotating shaft that enables the manipulator to have a welding station and a loading station. A tray for supplying glassware parts to the loading manipulator is arranged at a position corresponding to the loading station of the manipulator.

[0008] A further improvement of the technical solution of the utility model is that: the rotating shaft for installing the manipulator is installed on the sliding plate of the sliding seat which can move left and right through a fixed seat, and the rotating shaft is driven by the second pneumatic rod to realize the position change of the manipulator between the welding station and the loading station; the tray is also installed on the sliding seat corresponding to the bottom of the manipulator.

[0009] A further improvement of the above technical solution of the utility model is that: the second pneumatic rod is connected to the rotating shaft via an arc rod to realize 90° rotation of the rotating shaft.

[0010] The further improvement of the above technical solution of the utility model is that: a threaded rod for adjusting the height of the manipulator is arranged between the sliding plate and the bottom plate of the sliding seat; a first pneumatic rod is connected between the tray and the bottom plate of the sliding seat to move the tray up and down.

[0011] A further improvement of the technical solution of the utility model is that: the tray is provided with grooves or holes for accommodating and positioning glassware parts.

[0012] A further improvement of the technical solution of the utility model is that a plurality of glassware parts are arranged in a step-by-step manner in the groove or hole.

[0013] A further improvement of the technical solution of the utility model is that the manipulator comprises two clamping plates which are driven by a bidirectional cylinder to open and close simultaneously.

[0014] A further improvement of the above technical solution of the utility model is that: the clamping head of the clamping plate is provided with a positioning plate for positioning the glassware parts, and a clamping groove for the glassware parts is formed between the two clamping plates and the positioning plate.

[0015] A further improvement of the above technical solution of the utility model is that: a gravity holding block with an eccentric guide angle at the opening is connected to the upper part of the clamping plate by a pin shaft, and the center of gravity of the gravity holding block causes the opening of the gravity holding block to open relative to the positioning plate at the loading station and to close relative to the positioning plate at the welding station.

[0016] A further improvement of the above technical solution of the utility model is that a gap adjustment block for adjusting the gap between the two clamping plates is arranged on the inner side of the clamping head of the clamping plate through an adjustment bolt.

[0017] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model includes: by placing glassware parts such as cup handles on a tray, when the manipulator needs to clamp the parts, the manipulator is rotated downward by 90°, at which time the clamping groove is aligned with the parts placed on the tray, and then the tray drives the parts to move upward until the parts enter the clamping groove of the manipulator, and then the two clamping plates are driven to move toward each other by the two-way cylinder, so as to fix and clamp the parts, and then the tray is moved downward, at which time the tray is separated from the parts, and finally the manipulator is rotated upward by 90° to the original position, so as to finally achieve the purpose of fixing and clamping the parts by the manipulator. The manipulator of the clamping mechanism for producing glassware of the utility model is transferred between the welding station and the loading station, and the glassware parts are manually positioned on the tray, and the workers do not directly contact the hot manipulator. Since the tray is not burned by the flame, the temperature of the tray is low, which can prevent the workers from being scalded.

[0018] The manipulator of the utility model is driven by a pneumatic rod to realize the transition between the welding station and the loading station, with fast action speed and improved production efficiency. The threaded rod of the utility model is used to adjust the height of the manipulator during the equipment debugging process before production, that is, to adjust the relative height position between parts such as cup handles, which can adapt to the production of parts and glassware of different sizes or models; the grooves or holes set on the tray can accommodate the glassware parts and position them so that they can enter the manipulator accurately. The tray moves up and down to deliver the parts into the manipulator.

[0019] The practical manipulator and the tray can be provided with a plurality of corresponding grooves or holes for accommodating parts, which can improve production efficiency. In addition, a plurality of glassware parts can be placed in the grooves or holes for accommodating glassware parts at the same time, and the belt or push block or other structure of the stepping motor can be used to bring the parts to the loading station under the clamping plate of the manipulator in a stepping manner, which can further improve production efficiency.

[0020] The two clamping plates of the manipulator of the utility model open and close at the same time, and when clamping parts of different diameters or sizes, the center position of the clamped parts can be guaranteed, which is convenient for the alignment of the welding parts. The setting of the positioning plate further ensures the accurate clamping position of the parts. The setting of the gravity holding block and its guide angle can make the clamped parts more stable and convenient for entering the clamping groove. The setting of the adjustment block can adapt to the stable clamping of parts of different diameters or widths. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. In the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] The clamping mechanism of the utility model for producing glassware can refer to the attached drawings for specific configuration. Figure 1 , Figure 2 and Figure 3 It can be known that the utility model includes a robot 41 , and in this embodiment, three robot arms 41 are arranged on the second sliding seat 42 .

[0027] When the second sliding seat 42 is specifically set, please refer to Figure 1 and Figure 2 The second sliding seat 42 includes two vertical plates 422 arranged vertically, the bottom ends of the two vertical plates 422 are connected together through a horizontal bottom plate 421, and a sliding plate 423 that can move up and down and is arranged horizontally is also arranged between the two vertical plates 422.

[0028] When setting up the robot 41, please refer to Figure 3The manipulator 41 includes a second bidirectional cylinder 411 disposed on a mounting seat 426, and the two telescopic ends of the second bidirectional cylinder 411 are respectively provided with second clamping plates 412, and each second clamping plate 412 is connected to the telescopic end of the corresponding second bidirectional cylinder 411 through a connecting plate 413, and a positioning plate 414 is fixed to the bottom end of one of the second clamping plates 412, and the positioning plate 414 is used to position a certain end of the glassware part, which is lower than the lower edge of the other second clamping plate 412, and a cup handle clamping groove 418 is formed between the two second clamping plates 412. When clamping a part, the part enters the clamping groove 418 and makes a certain positioning surface contact with the positioning plate for positioning; and the cup handle clamping groove 415 is fixed to the bottom end of the second clamping plate 414, ... A rotatable holding block 416 corresponding to the positioning plate 414 is provided, and a rounded corner is provided at the bottom end of the holding block 416. The holding block 416 is connected to the two second clamping plates 412 through a movable pin 415. The holding block 416 cooperates with the positioning plate 414 by using its own gravity and eccentricity. When the second clamping plate 412 is in the loading station, the holding block 416 opens relative to the positioning plate 414 to facilitate the cup handle and other parts to enter the clamping groove 418. At the welding station, the outer end of the holding block 416 descends under the action of gravity, and presses the cup handle together with the positioning plate 414; and the two second clamping plates 412 driven by the second bidirectional cylinder 411 can open and close at the same time to clamp the cup handle from both sides. A limiting rod 417 for limiting the holding block 416 is arranged on the side of the movable pin shaft 415 for installing the holding block 416, so that a certain opening can be left between the holding block 416 and the positioning plate 414 in a natural state, so as to facilitate the insertion of the cup handle. The cup handle clamping mechanism 4 of the utility model also includes a height adjustment mechanism for adjusting the height of the manipulator 41. The height adjustment mechanism in this embodiment includes a threaded rod 424 threadedly connected to the sliding plate 423. The threaded rod 424 is vertically arranged and penetrates the sliding plate 423 downward to be rotatably connected to the bottom plate 421. A fixed seat 425 is fixedly provided on the sliding plate 423. A rotating shaft 428 is horizontally penetrated through the fixed seat 425. The rotating shaft 428 is connected to the fixed seat 425 through a bearing. One end of the rotating shaft 428 is fixedly connected to the mounting seat 426, and the other end of the rotating shaft 428 is hinged with a second arc rod 4232. A second pneumatic rod 4231 is arranged between the second arc rod 4232 and the sliding plate 423. The driving end of the second pneumatic rod 4231 is fixedly connected to the sliding plate 423, and the telescopic end of the second pneumatic rod 4231 is connected to the second arc rod 4232.

[0029] Continue to refer Figure 3 A gap adjustment block 419 for adjusting the gap between the two clamping plates 412 is provided between the two second clamping plates 421. The adjustment block 419 is connected to the second clamping plate 412 by an adjustment bolt 4191. The gap between the adjustment block 419 and the other clamping plate 412 can be adjusted by rotating the bolt, so that parts such as cup handles of different widths or diameters can be clamped.

[0030] Continue to refer Figure 1 and Figure 2 , a tray 429 that can move up and down is arranged below the mounting seat 426, and a first pneumatic rod 427 connected to the tray 429 is vertically arranged on the bottom plate 421, which can lift the tray 429 and send the parts on the tray 429 into the clamping groove. And the tray 429 is provided with a jack or groove for accommodating parts at the position corresponding to each manipulator 41. When the parts are placed in the groove or hole, the position is fixed, which is convenient for entering the clamping groove 418 between the clamping plates 412. The practical manipulator 41 and the tray 429 can be provided with a corresponding plurality of grooves or holes for accommodating parts, which can improve production efficiency. And a plurality of glassware parts can be arranged in the groove or hole for accommodating parts in a stepping manner, such as using a belt or push block or other structure of a stepping motor to drive the parts to enter the loading station under the clamping plate of the manipulator 41 in a stepping manner, which can further improve production efficiency.

[0031] The working principle of the clamping mechanism for producing glassware of the utility model is as follows: before preparing for production, the height positions of the sliding plate 423, the mounting seat 426 and the manipulator 41 are adjusted by rotating the threaded rod 424 until the manipulator 41 moves to a suitable working height.

[0032] When the utility model is used, by placing parts such as cup handles on the tray 429, when the manipulator 41 needs to clamp the parts, the second pneumatic rod 4231 is retracted, driving the arc rod 4232, the rotating shaft 428, the mounting seat 426 and the manipulator 41 to rotate 90 degrees counterclockwise. At this time, the clamping groove 418 of the manipulator 41 is aligned with the parts placed on the tray 429, and then the first pneumatic rod 427 is extended upward, thereby driving the tray 429 and the parts to move upward until the parts enter the clamping position of the manipulator 41. The two clamping plates 412 are moved toward each other through the bidirectional cylinder 411 to fix the parts, and then the first pneumatic rod 427 is retracted downward to drive the tray 429 to move downward. At this time, the tray 429 is separated from the parts. Finally, the second pneumatic rod 4231 is extended upward to drive the arc rod 4232, the rotating shaft 428, the mounting seat 426 and the manipulator 41 to rotate 90° clockwise to the original position, thereby finally achieving the purpose of fixing and clamping the parts through the manipulator 41.

[0033] When the part moves upward and enters the clamping groove 418, the part first contacts the fillet provided on the holding block 416. As the part continues to move upward, the holding block 416 can be lifted up, thereby preventing the holding block 416 from crushing the part.

[0034] In the above embodiment, the utility model provides a clamping mechanism for producing glassware, by placing parts on a tray, when the manipulator needs to clamp the parts, the manipulator rotates 90° counterclockwise, at which time the clamping groove is aligned with the parts placed on the tray, and then the tray drives the parts to move upward until the parts enter the clamping groove of the manipulator, and then the two clamping plates are driven to move toward each other by the bidirectional cylinder, so as to fix and clamp the parts, and then the tray is moved downward, at which time the tray is separated from the parts, and finally the manipulator rotates 90° clockwise to the original position, so as to finally achieve the purpose of fixing and clamping the parts by the manipulator. In the utility model, the worker does not directly contact the manipulator, but places the parts on the tray. Since the tray is not burned by the flame, the temperature of the tray is low, which can prevent the worker from being scalded.
