Description

Technical Field

[0001] This utility model belongs to the field of gas meter component production equipment, specifically relating to a load metering shell holding tray gripper assembly. Background Technology

[0002] The meter housing is one of the important components of a diaphragm gas meter. It is usually produced by stamping. The gas meter movement and the meter housing have sealing surfaces. After the main body is formed, a sealing strip is installed on the inside of the meter housing to further improve the sealing performance of the diaphragm cavity.

[0003] In the processing of metering shells, pallet loading and transfer are commonly used. During production, the applicant discovered that traditional pallets are not conducive to stacking; they are difficult to align vertically when stacking, or prone to tilting and jamming when removed. Furthermore, traditional pallets are not suitable for automated robotic arms and are difficult to adapt to automated production lines. Therefore, the applicant proposed a new pallet design and specifically developed a gripper structure for pallet loading. Utility Model Content

[0004] In view of this, the present invention provides a load metering shell holding pallet gripper assembly to solve the problem that there is no suitable new metering shell pallet gripping device in the prior art.

[0005] The technical solution is as follows:

[0006] A load metering shell holding pallet gripper assembly, the key features of which are: the pallet includes a plate-shaped body, the outer edge of the plate-shaped body has a flange bent upward along its thickness direction, the inner part of the pallet has a positioning boss symmetrically arranged along its length direction near the middle, and the bottom of the pallet has a positioning groove corresponding to the positioning boss.

[0007] The gripper assembly includes a gripper base C and a gripper drive mechanism C for driving the gripper base C to move up and down and horizontally;

[0008] The gripper base C includes a connecting beam C and multiple gripper mounting beams C. The gripper mounting beams C and the connecting beams C are both horizontally arranged and perpendicular to each other. Both ends of the gripper mounting beams C are equipped with gripper assemblies C. The gripper assembly C mainly includes a clamping cylinder. The piston rod of the clamping cylinder faces outward and is connected to a clamping plate. The bottom of the clamping plate has an inwardly horizontally bent portion.

[0009] Using the above solution, since it is no longer convenient to grasp the pallet using the placement hole after the metering shell is installed, a clamping structure is set up by combining the new pallet structure and using the positioning groove. When grasping, the bent part at the bottom of the clamping piece extends into the positioning groove, which can pick up the pallet and then transfer it through the drive mechanism C.

[0010] Preferably, the flange has at least two sets of clamping openings symmetrically arranged in pairs along the width direction;

[0011] The gripper base C has a gripper assembly C corresponding to the clamping port, and the inner side of the clamping plate has a clamping groove adapted to the clamping port.

[0012] By adopting the above solution, the clamping slot and clamping opening work together to improve the stability of pallet gripping and transfer process, prevent skewing, and also enable better stacking to prevent jamming.

[0013] Preferably, the gripper mounting beam C at both ends is provided with elastic clamping plates, at least two of which are diagonally distributed, and the elastic clamping plates are fixed to the gripper mounting beam C by elastic connectors. With this design, the clamping plates apply downward pressure to the pallet during gripping, and the upward gripping force of the clamping plates further improves the stability of the pallet during the process, reducing shaking, etc.

[0014] Preferably, the elastic clamping sheet is three-sided and has an outwardly sloping flange at the bottom. This design better restricts the pallet's posture.

[0015] Preferably, the gripper drive mechanism C includes two horizontally arranged X-direction gripper guide rails C, a Y-direction base C that slides with the X-direction gripper guide rails C, a Z-direction base C that slides with the Y-direction base C, and the lower end of the Z-direction base C being fixedly connected to the gripper base C.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The load metering shell pallet gripper assembly provided by this utility model, combined with a novel pallet structure, proposes a targeted gripping and clamping structure that can stably grip and transfer pallets, facilitate stacking, and avoid affecting the metering shells placed on the pallet.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] refer to Figures 1 to 7 The load metering shell pallet gripper assembly shown is illustrated below. For ease of understanding, the structure of the new pallet 600 will be described first, with a focus on references to... Figure 3 and Figure 4 The tray 600 includes a plate-shaped body 610. The outer edge of the plate-shaped body 610 has an upwardly bent flange 620 along its thickness direction. The plate-shaped body 610 has a plurality of spaced placement holes 611, which allow the metering shell to be placed with its concave surface facing upward. The outer edge of the metering shell is supported on the plate-shaped body 610. The bottom of the plate-shaped body 610 has at least three evenly distributed support columns 612. The height of the support columns 612 is greater than the depth of the metering shell. This ensures that when the two trays 600 are stacked, the metering shell in the upper tray will not contact the metering shell in the lower tray.

[0027] In this embodiment, the plate-shaped main body 610 is generally rectangular plate-shaped structure, with hand grips 613 at both ends in the length direction, and at least two sets of clamping openings 621 symmetrically arranged in the width direction on the flange 620.

[0028] The pallet 600 has a positioning boss 630 symmetrically arranged along its length near the center. The bottom of the pallet has a positioning groove 640 corresponding to the positioning boss 630. When the two pallets 600 are stacked, the positioning boss 630 of the lower pallet can be inserted into the positioning groove 640 of the upper pallet.

[0029] Furthermore, to further improve the stability of pallet stacking, an inwardly recessed ridge 650 is provided along the outer edge of the bottom of the plate-shaped body 610. The inwardly recessed ridge 650 and the plate-shaped body 610 form a first positioning step. At the same time, the four corners of the plate-shaped body 610 have generally L-shaped positioning pieces 614. The positioning pieces 614 are located inside the inwardly recessed ridge 650 and form a second positioning step with the inwardly recessed ridge 650. The two positioning steps work together to fully ensure the stability of pallet stacking. In addition, the corners of the plate-shaped body 610, the flange 620, the inwardly recessed ridge 650 and the positioning pieces 614 are all rounded. The stepped positioning structure also facilitates the quick alignment and stacking of pallets, as well as the removal of the upper pallet, improving ease of use.

[0030] When the trays 600 are stacked, the vertical distance between the two plate-shaped bodies 610 is the height of the positioning piece 614. In this embodiment, the horizontal thickness of the L-shaped bottom of the abutment block 4314 is adapted to this height, its width is less than the width of the placement hole 611, and the distance between the two abutment blocks 4314 is greater than the length of the placement hole 611.

[0031] Based on the pallet structure described above, the gripper assembly of this application mainly includes a gripper base C531 and a gripper drive mechanism C532 for driving the gripper base C531 to move up and down and horizontally. The gripper base C531 includes a connecting beam C5310 and multiple gripper mounting beams C5311. The gripper mounting beams C5311 and the connecting beams C5310 are both horizontally arranged and perpendicular to each other. Both ends of the gripper mounting beams C5311 are equipped with gripper assemblies C. The gripper assembly C mainly includes a clamping cylinder 5312. The piston rod of the clamping cylinder 5312 faces outward and is connected to a clamping plate 5313. The clamping plate 5313 is vertically arranged and has an inwardly horizontally bent portion at its bottom. It should be noted that in order to facilitate the gripping of the pallet and prevent interference, the thickness of the bent portion is less than the height of the protrusion 650.

[0032] The gripper base C531 has a gripper assembly C that corresponds to the clamping port 621 on the tray. That is, a gripper mounting beam C5311 is also provided for the corresponding clamping port 621. The inner side of the clamping plate 5313 has a clamping groove 5314 that is adapted to the clamping port 621.

[0033] In addition, elastic clamping plates 5315 are provided on the gripper mounting beams C5311 at both ends, as shown in the figure. There are at least two elastic clamping plates 5315, which are diagonally distributed. The elastic clamping plates 5315 are fixed to the gripper mounting beams C5311 by elastic connectors 5316, as shown in the figure. In this embodiment, the elastic connectors 5316 are springs. At the same time, a guide structure is provided between the elastic clamping plates 5315 and the gripper mounting beams C5311 to restrict the movement direction of the elastic clamping plates 5315. In specific implementation, the elastic clamping plates 5315 are three-sided and have outwardly sloping flanges at the bottom, which can reduce the risk of collision with the pallet during lifting.

[0034] In specific implementation, the gripper drive mechanism C532 includes two horizontally arranged X-direction gripper guide rails C5320, a Y-direction base C5321 that slides with the X-direction gripper guide rails C5320, a Z-direction base C5322 that slides with the Y-direction base C5321, and the lower end of the Z-direction base C5322 that is fixedly connected to the gripper base C531. In specific implementation, the Y-axis base C5321 has a Z-axis base C5322 that slides with it. The lower end of the Z-axis base C5322 is fixedly connected to the gripper base C531. Simultaneously, the X-axis gripper guide rail C5320 has an X-axis rack C5323 arranged parallel to it, and an X-axis gear C5324 meshing with the X-axis rack C5323. The Y-axis base C5321 has an X-axis motor C5325 for driving the X-axis gear C5324 to rotate. The Z-axis base C5322 is vertically arranged, with its lower end fixedly connected to the connecting beam C5310. One side of the Z-axis base C5322 has a Z-axis rack C5326 fixed to and parallel to it, with a Z-axis gear C5327 meshing with it. The Y-axis base C5321 has a Z-axis motor C5328 for driving the Z-axis gear C5327 to rotate.

[0035] refer to Figures 1 to 7 The load metering shell pallet gripper assembly shown is mainly used in the metering shell gluing system. As shown in the figure, the metering shell gluing system includes a pallet supply unit 400 and a pallet transfer unit 500. The pallet supply unit 400 mainly includes an empty pallet stacking station 410, a pallet transfer line 420 corresponding to the empty pallet stacking station, and the empty load metering shell pallet gripper assembly 430 of this application. The pallet transfer line 420 includes at least a pallet placement position and a pallet waiting position. The empty load metering shell pallet gripper assembly 430 of this application is used to grab the empty pallet in the empty pallet stacking station 410 and place it in the pallet placement position, and then the pallet transfer line 420 transports it to the pallet waiting position.

[0036] The pallet transfer unit 500 mainly includes a pallet fixing station and a full-load pallet stacking station, as well as a pallet fixing component and a metering shell gripper assembly 520 corresponding to the pallet fixing station, and a load metering shell pallet holding gripper assembly 530 for gripping and placing the pallet at the pallet fixing station to the full-load pallet stacking station. The metering shell gripper assembly is used to grip and place the metering shell at the material picking station on the batch gluing device into the pallet at the pallet fixing station.

[0037] Specifically, the pallet supply unit 400 and the pallet transfer unit 500 share a main frame beam structure, which is mainly composed of columns, beams and protective fences. During installation, the X-axis gripper guide rail C5320 covers the pallet fixing station and the full-load pallet stacking station 540. During implementation, the X-axis gripper guide rail C5320 is fixed to the top of the main frame beam structure. When the pallet in the pallet fixing position is filled with the metering shell, the full-load pallet gripper assembly 530 starts to work. The gripper seat C531 descends facing the full-load pallet and first contacts and presses against the upper surface of the pallet. Then, the gripper assembly C clamps the two sides of the pallet. Then, the gripper drive mechanism C rises and moves horizontally to the full-load pallet stacking station. Multiple full-load pallets are stacked up and down in sequence to facilitate subsequent rapid transfer.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
