Description

Technical Field

[0001] The invention relates to the technical field of sealing rubber ring production, in particular to a stacking device for sealing rubber rings. Background Art

[0002] In the actual production process of sealing rubber rings, a large number of rubber rings can be produced at the same time during a die-casting process on one device. Too many rubber rings and their messy placement may affect the aesthetics and cleanliness of the factory workshop, so a stacking device is needed to sort and organize them.

[0003] In the prior art, there is a utility model patent with a publication (announcement) number of CN212890426U and a name of a transportation device based on sealing rings, which includes a storage box and a hanging rod. The left and right sides of the inner surface of the storage box are fixed with clamping components, and the left and right ends of the hanging rod are fixedly connected with connecting blocks. A first telescopic groove is opened inside the connecting block, and a first spring is arranged inside the first telescopic groove. One end of the first spring is fixedly connected with a clamping block; the transportation device based on sealing rings is achieved by stringing the sealing rings on the hanging rod, and the hanging rod is fixed by the connecting block and the clamping component. During transportation, the sealing rings will not be scattered everywhere, but are evenly distributed, which is very convenient to take and use. At the same time, the volume is reduced. The storage box can also store more sealing rings. Rollers are arranged at the bottom of the storage box, and a handle is arranged on the other side to facilitate the staff to transport the sealing pads without manual handling, saving time and effort.

[0004] The device of the patent strings the sealing rings on the hanging rod so that the sealing rings will not scatter everywhere during transportation and are evenly distributed. However, the device of the patent still has the following technical defects during use: (1) Since the device of the patent does not limit the sealing rings strung on the hanging rod, adjacent sealing rings are prone to collision with each other, which can easily damage the sealing rings; (2) When using the device of the patent, it is necessary to manually disassemble the hanging rod, string the sealing rings on the hanging rod, and finally install the hanging rod to complete the stacking of the sealing rings. The overall operation steps are relatively cumbersome and inconvenient for staff to use. Summary of the invention

[0005] The purpose of the present invention is to provide a stacking device for sealing rubber rings.

[0006] The technical problems solved by the present invention are: (1) the existing equipment is not convenient for limiting the position of multiple stacked sealing rings, which makes it easy for adjacent sealing rings to collide with each other, and thus easily damage the sealing rings; (2) the existing equipment is not convenient for quickly stacking the sealing rings.

[0046] See also Figure 7-10As shown, the transfer box 5 includes a mobile frame 51 fixed thereto, a mounting plate 52 is fixedly installed in the inner cavity of the mobile frame 51, a cylinder 53 is fixedly installed at the middle end of the bottom of the mounting plate 52, a lifting frame 54 vertically slidably connected to the inner cavity of the mobile frame 51 is fixedly installed at the output end of the cylinder 53, a second electric telescopic rod 55 is fixedly installed at the bottom end of the inner cavity of the lifting frame 54, a mobile plate 56 vertically slidably connected to the inner cavity of the lifting frame 54 is fixedly installed at the output end of the second electric telescopic rod 55, a plurality of supporting cylinders 58 are fixedly installed equidistantly between the transfer box 5 and the lifting frame 54, a round table 571 is vertically slidably connected to the inner cavity of the supporting cylinder 58, and the round table The bottom of 571 is fixedly connected to the moving plate 56 through the transmission rod 57, and the inner cavity of the supporting cylinder 58 is slidably connected with at least four inclined plates 572 that abut against the inclined surface of the truncated table 571. An inner groove is provided on the side of the inclined plate 572 close to the inner cavity of the supporting cylinder 58, and an extrusion spring 573 fixedly connected to the inner cavity of the supporting cylinder 58 is fixedly installed in the inner groove of the inclined plate 572. A cylindrical clamping piece 574 corresponding to it is fixedly installed on the top of the inclined plate 572. A circular through groove 59 with the same number as the supporting cylinder 58 is penetrated through the bottom wall of the transport box 5, and the setting of the circular through groove 59 provides space for the movement of the four cylindrical clamping pieces 574;

[0047] An opening and closing door 510 is rotatably connected to one side of the transfer box 5, a sealing plug is fixedly installed on one side of the opening and closing door 510, and the inner cavity of the transfer box 5 is provided with a sealing slot that matches the sealing plug.

[0048] When the present invention is in use, the transfer box 5 is first moved onto the bottom plate 1, and then the fixed clamping plates 64 on the two rotating seats 63 are rotated in opposite directions so that the transfer box 5 can enter between the two limiting plates 61. After the transfer box 5 enters the working position, the two fixed clamping plates 64 are rotated to reset it, and the two first electric telescopic rods 62 are driven at the same time. The two fixed clamping plates 64 are abutted against the outer wall of the transfer box 5 by shortening the first electric telescopic rods 62, so as to facilitate its limiting.

[0049] After the transfer box 5 is limited, the transmission belt 42 is allowed to run, and then the sealing rubber ring to be stacked is placed on the transmission belt 42. The correction plates 45 fixed on both sides of the inner cavity of the conveyor belt bracket 41 facilitate the position correction of the sealing rubber ring entering the transmission belt 42. By correcting its position, it is convenient for the robot arm mechanism 2 to pick it up. When the sealing rubber ring is transported to the bottom of the robot arm mechanism 2 by the transmission belt 42, the transmission belt 42 stops running, and the limiting clamping plate 35 at the bottom of the fixed cylinder 33 enters the inner cavity of the sealing rubber ring by controlling the first robot arm 22, the second robot arm 23 and the third robot arm 24. The operation of the electric push rod 337 makes the rack 338 slide, and the rack 338 rotates the gear 336 through the meshing action, and the rotation of the gear 336 drives the turntable 332 to rotate, and the arc-shaped sliding groove 335 opened in the inner cavity of the turntable 332 and the fixed column 334 on the linkage plate 333 The mutual cooperation makes the three limiting clamping plates 35 move relative to each other, so as to facilitate the clamping of the sealing rubber ring. After the sealing rubber ring is clamped, the first mechanical arm 22, the second mechanical arm 23 and the third mechanical arm 24 are controlled to enable the sealing rubber ring to reach the corresponding position in the corresponding transfer box 5, and the electric push rod 337 is driven again to release the limit of the sealing rubber ring so that it can fall into the outer wall of the four cylindrical clamping members 574. Such a reciprocating cycle can realize the stacking work of multiple sealing rubber rings, and the stacking work is carried out until the outer wall of the cylindrical clamping members 574 is completely covered with sealing rubber rings; similarly, multiple groups of cylindrical clamping members 574 are arranged in the transfer box 5. Since the number of each group of cylindrical clamping members 574 is four, after the stacking work of one group of cylindrical clamping members 574 is completed, the stacking work of another group of cylindrical clamping members 574 can be carried out through the mechanical arm mechanism 2 until the stacking work is completed;

[0050] After the sealing rubber rings are stacked, the stacked sealing rubber rings are limited by driving the second electric telescopic rod 55, and the moving plate 56 is moved upward by extending the second electric telescopic rod 55. The movement of the moving plate 56 facilitates the synchronous upward movement of the round tables 571 corresponding to the inner cavities of the multiple supporting cylinders 58, and the movement of the round tables 571 causes the four inclined plates 572 to slide along the side away from the inclined surface of the round tables 571. The sliding of the four inclined plates 572 causes the corresponding cylindrical clamps 574 to move synchronously, thereby facilitating the limiting of the inner walls of the multiple sealing rubber rings through the movement of the four cylindrical clamps 574. By limiting the inner walls, collisions between adjacent sealing rubber rings are avoided, thereby facilitating the subsequent transportation of the sealing rubber rings through the transfer box 5, and the limiting of the transfer box 5 is released before transportation;

[0051] After the transfer box 5 is transported to the working position, when the sealing rubber ring needs to be unloaded, the opening and closing door 510 can be opened first, and then the cylinder 53 can be driven. The shortening of the cylinder 53 can make the lifting frame 54 move downward, and the downward movement of the lifting frame 54 can make the cylindrical clamping piece 574 that limits the sealing rubber ring move downward synchronously. The downward movement of the cylindrical clamping piece 574 facilitates the release of the sealing rubber ring and facilitates the unloading of the sealing rubber ring.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
