Description
Technical Field
[0001] This utility model belongs to the field of mechanical gripper technology, specifically relating to a gripper assembly for an empty metering shell containing a pallet. 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, based on a new pallet design, the applicant has specifically proposed a gripper structure for use when the pallet is unloaded. Utility Model Content
[0004] In view of this, the present invention provides an empty metering shell pallet gripper assembly to solve the problems of inconvenient pallet gripping and inconsistent postures in the prior art.
[0005] The technical solution is as follows:
[0006] An empty metering shell container pallet gripper assembly includes a gripper base A and a gripper drive mechanism A for driving the gripper base A to move. The key feature is that the gripper base A includes at least one gripper mounting beam A and gripper assemblies A respectively mounted on both ends of the two gripper mounting beams A and symmetrically arranged.
[0007] The gripper assembly A includes a clamping cylinder arranged along the length of the gripper mounting beam A. The piston rod of the clamping cylinder faces outward and is connected to a pressing cylinder. The piston rod of the pressing cylinder faces downward and is equipped with a clamping block.
[0008] The abutting block faces outwards and has an L-shaped cross-section. The abutting block has a bottom contact surface and a side contact surface.
[0009] Using the above solution, when in use, the lower L-shaped part of the clamping block passes through the placement hole of the pallet from above, and then moves outward by the clamping cylinder, so that the bottom contact surface and the side contact surface abut against the bottom surface of the pallet and the side wall of the placement hole respectively, which can pick up the pallet and fully ensure the consistency of the pallet's posture during transportation and placement.
[0010] Preferably, each end of the clamping block along the width of the gripper mounting beam A is connected to a pressing block, and there is a gap between the pressing surface of the pressing block and the bottom contact surface, which is adapted to the thickness of the pallet. With this design, the pressing surface and the bottom contact surface contact the upper and lower surfaces of the pallet respectively, effectively forming a clamping posture, which helps to further improve the stability of pallet gripping and transport.
[0011] Preferably, the gripper mounting beam A is included, and the gripper mounting beam A is distributed along the length direction of the connecting beam A;
[0012] The connecting beam A has a locking groove along its length, and the gripper mounting beam A is fixed to the connecting beam A by locking screws. This design improves the adaptability of the gripper assembly, allowing for convenient adjustment of the spacing between the gripper mounting beams A as needed, accommodating various pallet sizes.
[0013] Preferably, the gripper drive mechanism A includes two horizontally arranged X-direction gripper guide rails A and a Y-direction base A that slides with the X-direction gripper guide rails A;
[0014] The Y-axis base A has a Z-axis base A that slides with it, and the lower end of the Z-axis base A is fixedly connected to the gripper base A.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] The empty metering shell pallet gripper assembly provided by this utility model fully utilizes the height between pallet stacks, greatly improving gripping balance and preventing pallet tilting and jamming that would make it difficult to separate the upper and lower parts. It also ensures the consistency of the transport and placement posture, which is beneficial to the next process. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.
[0025] refer to Figures 1 to 7 The empty metering shell container pallet gripper assembly shown mainly includes a gripper base A431 and a gripper drive mechanism A432 for driving the gripper base A431 to move. The gripper base A431 includes at least one gripper mounting beam A4311 and gripper assemblies A that are respectively mounted on both ends of the gripper mounting beam A4311 and are symmetrically arranged.
[0026] The gripper assembly A includes a clamping cylinder 4312 arranged along the length of the gripper mounting beam A4311. The piston rod of the clamping cylinder 4312 faces outward and is connected to a pressing cylinder 4313. The piston rod of the pressing cylinder 4313 faces downward and is equipped with a clamping block 4314.
[0027] like Figure 3 As shown, the abutment block 4314 faces outward, and its cross-section is L-shaped. The abutment block 4314 has a bottom contact surface 43141 and a side contact surface 43140.
[0028] Both ends of the clamping block 4314 along the width direction of the gripper mounting beam A4311 are connected to clamping blocks 4315. There is a gap between the clamping surface of the clamping block 4315 and the bottom contact surface 43141, and the gap is adapted to the thickness of the tray.
[0029] In specific implementation, it also includes a connecting beam A4310, a gripper mounting beam A4311 distributed along the length direction of the connecting beam A4310, a locking groove 43100 provided along its length direction on the connecting beam A4310, and the gripper mounting beam A4311 fixed to the connecting beam A4310 by locking screws. Two gripper assemblies A on the same gripper mounting beam A4311 are symmetrically arranged relative to the connecting beam A4310.
[0030] As shown in the figure, the gripper drive mechanism A432 mainly includes two horizontally arranged X-direction gripper guide rails A4320, and a Y-direction base A4321 that slides with the X-direction gripper guide rails A4320. In implementation, the Y-direction base A4321 has a Z-direction base A4322 that slides with it. The lower end of the Z-direction base A4322 is fixedly connected to the gripper base A431. Meanwhile, the X-direction gripper guide rails A4320 have an X-direction rack A4323 arranged parallel to it, and a rack A4323 that slides with it. An X-axis gear A4324 meshes with an X-axis rack A4323. An X-axis motor A4325 for driving the X-axis gear A4324 to rotate is located on a Y-axis base A4321. A Z-axis base A4322 is vertically arranged, and a Z-axis rack A4326 is fixed and parallel to it on one side. A Z-axis gear A4327 meshes with the Z-axis rack A4326. A Z-axis motor A4328 for driving the Z-axis gear A4327 to rotate is located on a Y-axis base A4321.
[0031] refer to Figures 1 to 7 The empty metering shell holding pallet gripper assembly shown includes a pallet 600 comprising 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 concavely into them. 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 pillars 612. The height of the support pillars 612 is greater than the depth of the metering shell, which ensures that when the two pallets 600 are stacked, the metering shell in the upper pallet will not contact the metering shell in the lower pallet.
[0032] In this embodiment, the plate-shaped main body 610 is generally rectangular plate-shaped, 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] The empty metering shell pallet gripper assembly of this application 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 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 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.
[0037] 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 corresponding to the pallet fixing station, and a full-load pallet 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 of the batch gluing device into the pallet at the pallet fixing station.
[0038] 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. The X-axis gripper guide rail A4320 covers the empty pallet stacking station 410 and the pallet placement position. The X-axis gripper guide rail A4320 is fixed to the top of the main frame beam structure. The empty pallet stacking station 410 is used to stack empty pallets. The spacing between adjacent gripper mounting beams A4311 is an integer multiple of the placement holes 611 on the pallet. During use, the empty pallet in the empty pallet stacking station 410 can be gripped and placed into the pallet placement position using the empty metering shell pallet gripper assembly of this application. During operation, the gripper drive mechanism... A drives the gripper base A431 to reach its approximate position, with the gripper assembly A aligned with the placement hole 611. Then, the clamping cylinder 4313 drives the abutment block 4314 to move downwards until the clamping block 4315 contacts the upper surface of the tray. The L-shaped bottom of the abutment block 4314 is positioned below the tray. Then, the clamping cylinder 4312 drives the abutment block 4314 to move horizontally outwards, so that the bottom contact surface 43141 of the abutment block 4314 is in contact with the bottom surface of the tray near the placement hole, while the side contact surface 43141 abuts against the side of the placement hole 611. This achieves the gripping of the tray and ensures sufficient gripping balance, preventing tilting that could make it difficult to separate the upper and lower trays.

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.
