Description

Technical Field

[0001] This invention relates to the field of washing machine counterweight production equipment technology, and in particular to an automatic demolding and transfer device for washing machine counterweights. Background Technology

[0002] The counterweight of a washing machine is a core functional component that maintains the machine's balance during the spin-drying and high-speed operation phases. Its performance directly affects the stability, noise level, and lifespan of the washing machine. Currently, due to cost, density, and compatibility with molding processes, cement-based counterweights remain the mainstream choice in the industry. In the existing production process, after the cement counterweights are poured, the molds need to be manually disassembled, and then the solidified counterweights need to be manually removed from the molds before being manually transported to designated areas for stacking.

[0003] However, due to the need to meet counterweight requirements, the weight of a single cement counterweight block is usually 1.8 to 2.5 kg, and the weight of some large-capacity washing machine counterweight blocks can reach 3.5 to 4 kg. In order to adapt to the inner drum structure of the washing machine, the counterweight blocks are often designed in irregular shapes (such as arc shape, L shape) without regular gripping surfaces. At the same time, the solidified cement block has a strong adhesion to the mold wall. Currently, the manual demolding method is labor-intensive. Workers need to exert repeated force during manual demolding and transportation, which can easily lead to muscle strain in the long run and is difficult to meet the needs of large-scale production. Therefore, we propose an automatic demolding and transfer device for washing machine counterweight blocks to solve the above problems. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies where manual demolding and stacking of cement counterweights for washing machines after casting results in high labor intensity, low production efficiency, and significant safety hazards. It provides an automatic demolding and transfer device for washing machine counterweights.

[0005] This invention is achieved through the following technical solution: An automatic demolding and transfer device for washing machine counterweights includes a truss. The truss is provided with a frame removal and demolding area, a demolding separation area and a finished product stacking area. The top of the truss is provided with three moving mechanisms. The bottom of the three moving mechanisms is respectively equipped with a demolding gripper, a demolding gripper and a stacking gripper. The moving mechanisms can drive the demolding gripper, the demolding gripper and the stacking gripper to move up and down, left and right and forward and backward. The mold removal area is equipped with a mold removal frame for placing the mold, and the mold removal claws grab the mold and transfer it to the mold removal separation area for demolding. The demolding separation area is equipped with a transfer mechanism and a testing table. The counterweight is separated from the mold by the demolding gripper, and the upper and lower molds are transported and recovered by the transfer mechanism. During the demolding process, the surface quality of the counterweight is tested by the testing table. The finished product palletizing area is equipped with a palletizing platform. The palletizing grippers pick up the counterweights that have passed the quality inspection and transfer them to the palletizing platform for stacking.

[0006] In a preferred embodiment of the present invention, each of the moving mechanisms is equipped with a 3D camera, and the truss is equipped with a display screen electrically connected to the 3D camera. The workpiece coordinates are obtained by taking pictures with the 3D camera and the target position is displayed on the display screen.

[0007] In a preferred embodiment of the present invention, the mold-grabbing gripper includes a first connecting seat and a rotating base plate rotatably mounted on the side wall of the first connecting seat. The rotating base plate is driven by a first servo motor mounted on the first connecting seat, and a first bidirectional cylinder is mounted on the bottom end of the rotating base plate. Finger plates are fixed on the output shafts at both ends of the first bidirectional cylinder. The operation of the first bidirectional cylinder drives the two finger plates to move closer to each other to grasp the mold. After grasping, the first servo motor drives the rotating base plate to rotate, so that the mold is placed flat on the transfer table.

[0008] In a preferred embodiment of the present invention, a tilting cylinder is installed on the outer wall of one side of the finger plate via a connecting plate. The telescopic end of the tilting cylinder is provided with a pulling block. Before the mold is gripped, the tilting cylinder drives the pulling block to tilt the mold, so that the mold leans against one side of the finger plate, thereby facilitating the two finger plates to cooperate with each other to grip the mold.

[0009] In a preferred embodiment of the present invention, the transfer mechanism includes a transfer platform for placing the mold to be disassembled, and conveyor belts installed on both sides of the transfer platform. The conveyor belts are equipped with a first detection sensor to determine whether the lower mold and cement block have fallen off.

[0010] In a preferred embodiment of the present invention, the mold disassembly gripper includes a support frame and two clamping plates slidably installed on both sides of the bottom of the support frame. A second bidirectional cylinder is installed at both ends of the support frame. The output shafts at both ends of the second bidirectional cylinder are fixedly connected to the clamping plates on both sides. The two clamping plates are driven to move closer to each other by the second bidirectional cylinders on both sides to grip the mold. Both of the clamping plates are equipped with ejector cylinders on their inner walls. The two ejector cylinders are arranged diagonally, and a pneumatic hammer is installed at the bottom center of the support frame. The ejector cylinders are used to push the lower mold of the mold to separate the lower mold from the overall mold. The pneumatic hammer is used to hammer the upper mold after the lower mold is separated to make it vibrate and separate the cement counterweight block from the upper mold.

[0011] In a preferred embodiment of the present invention, the testing platform includes a support base and a fixed platform and a flipping platform disposed on the top of the support base. The side of the flipping platform near the fixed platform is rotatably mounted on the support base via a rotating shaft, and one end of the rotating shaft is provided with a second servo motor for driving it. The fixed platform is equipped with matching second detection sensors on both sides. The surface quality of the counterweight is detected by the second detection sensors so as to know in time whether the counterweight is qualified.

[0012] In a preferred embodiment of the present invention, the flipping platform has multiple slots arranged linearly, and a clamping cylinder is installed at the bottom of the flipping platform. The output end of the clamping cylinder is fixed with a mounting plate, and multiple extrusion rods are vertically fixed on the mounting plate. The extrusion rods are inserted into the slots and slide in cooperation with the slots. The clamping cylinder drives the extrusion rods to move, so that the extrusion rods cooperate with the flipping platform to clamp and fix the counterweight, thereby facilitating the flipping of the counterweight.

[0013] In a preferred embodiment of the present invention, the palletizing gripper includes a second connecting seat and a third bidirectional cylinder installed at the bottom of the second connecting seat. Both ends of the output shaft of the third bidirectional cylinder are equipped with contouring claws. By adapting the contouring claws to the irregular cement counterweight, the gripping strength of the counterweight is improved.

[0014] In a preferred embodiment of the present invention, a rotating seat is provided between the second connecting seat and the third bidirectional cylinder. The third bidirectional cylinder is fixedly connected to the rotating seat, and a rotary motor is installed on the second connecting seat to drive the rotating seat to rotate circumferentially. The rotary motor drives the third bidirectional cylinder to rotate circumferentially, thereby enabling circumferential fine adjustment of the gripping position of the contour claw, which facilitates the gripping of the counterweight.

[0015] The beneficial effects of this invention are: 1. This invention achieves an integrated process of demolding and stacking of washing machine counterweights by using a combination of mold-taking grippers, demolding grippers, and stacking grippers, which greatly reduces the workload of workers, eliminates the need for direct manual operation of heavy objects, and meets the needs of large-scale production. 2. In this invention, during the demolding process of the counterweight block, the quality of the front and back surfaces of the counterweight block is directly detected by the cooperation of the flipping table and the second detection sensor, so as to understand the quality of the counterweight block in a timely manner, reduce defective products, and avoid subsequent detection steps.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention. The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding the present invention, and not for limiting the present invention.

[0019] like Figure 1-10 The automatic demolding and transfer device for washing machine counterweights shown includes a truss 1. Top beams 2 are installed on both sides of the top of the truss 1. Three moving mechanisms 3 are slidably installed between the two top beams 2. The bottom ends of the three moving mechanisms 3 are respectively equipped with a demolding gripper 5, a demolding gripper 7, and a stacking gripper 10. The moving mechanism 3 is an existing structure, mainly including sliding seats 32 slidably installed on the two top beams 2. A crossbeam 31 is fixed between the two sliding seats 32. A mounting seat 33 is slidably installed on the crossbeam 31. A vertical beam 34 is slidably installed on the mounting seat 33 in the vertical direction. The crossbeam 31 is provided with a tool for... The bellows cover 36, which is a movable auxiliary component for shielding, is connected to the sliding seat 32 and the top beam 2, the mounting seat 33 and the cross beam 31, and the mounting seat 33 and the vertical beam 34 through gears and racks and driven by a motor. This, in turn, drives the mold-removing gripper 5, the mold-unmolding gripper 7, and the stacking gripper 10 to move up and down, left and right, and forward and backward. At the same time, each moving mechanism 3 is equipped with a 3D camera 35, and the truss 1 is equipped with a display screen electrically connected to the 3D camera 35. The 3D camera 35 takes pictures to obtain the coordinates of the workpiece for accurate gripping, and displays the target position on the display screen. The truss 1 has three areas: a frame disassembly and mold removal area, a mold disassembly and separation area, and a finished product stacking area. The mold removal area is equipped with a mold removal frame 4 for placing the mold. The counterweight block of the mold after casting is placed in the mold removal frame 4, and the moving mechanism 3 drives the mold removal claw 5 to grab the mold and move it to the mold removal separation area for demolding. The mold-taking gripper 5 includes a first connecting seat 51 installed at the bottom end of the vertical beam 34 in the moving mechanism 3 and a rotating base plate 52 rotatably installed on the side wall of the first connecting seat 51. The rotating base plate 52 is driven by a first servo motor 53 installed on the first connecting seat 51, and a first bidirectional cylinder 54 (a bidirectional cylinder is a cylinder whose output shafts at both ends can extend or retract simultaneously) is installed at the bottom end of the rotating base plate 52. Finger plates 55 are fixed on both output shafts of the first bidirectional cylinder 54. A tilting cylinder 56 is installed on the outer wall of one finger plate 55 through a connecting plate. The tilting cylinder 56 is set perpendicular to the finger plate 55 and tilts the finger plate. The telescopic end of the cylinder 56 is equipped with a pull block. Before gripping the mold, the pull block is driven by the cylinder 56 to tilt the mold so that it rests against one side finger plate 55. This facilitates the two finger plates 55 to cooperate in gripping the mold. During gripping, the operation of the first bidirectional cylinder 54 drives the two finger plates 55 to move closer to each other to grip the mold. After gripping, the moving mechanism 3 moves the mold to the demolding separation area. After reaching the designated position, the first servo motor 53 drives the rotating base plate 52 to rotate so that the mold is placed flat on the transfer table 61 in the demolding separation area. The demolding separation area is equipped with a transfer mechanism 6 and a testing platform 8. The transfer mechanism 6 includes a transfer platform 61 for placing the mold to be demolded, and conveyor belts 62 installed on both sides of the transfer platform 61. The conveyor belts 62 are equipped with a first detection sensor 63 (such as an image sensor). During the demolding process, the demolding gripper 7 grabs the mold on the transfer platform 61. First, the lower mold is disassembled, causing it to fall onto the conveyor belt 62 for removal. The first detection sensor 63 determines whether the lower mold and cement block have fallen off. After the lower mold falls off, the moving mechanism 3 moves the upper mold and counterweight to the top of the testing platform 8. The counterweight is disassembled again, causing it to fall onto the testing platform 8 for testing. Finally, the moving mechanism 3 transfers the upper mold to another conveyor belt 62 for further transfer. The testing table 8 includes a support base 81, a fixed platform 84 and a tilting platform 86 disposed at the top of the support base 81. The tilting platform 86 is rotatably mounted on the support base 81 via a rotating shaft 82 on the side near the fixed platform 84. A second servo motor 83 for driving the rotating shaft 82 is provided at one end. The tilting platform 86 has multiple slots 87 arranged linearly. A clamping cylinder 88 is installed at the bottom of the tilting platform 86. A mounting plate 89 is fixed to the output end of the clamping cylinder 88 and is slidably mounted on the tilting platform 86. At the bottom, and on the mounting plate 89, there are multiple pressing rods 810 vertically fixed. The pressing rods 810 are inserted into the slots 87 and slide in cooperation with the slots 87. The pressing rods 810 are moved by the clamping cylinder 88, so that the pressing rods 810 cooperate with the flipping table 86 to clamp and fix the counterweight, which facilitates the flipping of the counterweight. Furthermore, the two sides of the fixing table 84 are equipped with compatible second detection sensors 85 (such as image sensors). The surface quality of the counterweight is detected by the second detection sensors 85 to determine whether the counterweight is qualified in a timely manner. The specific structure of the demolding gripper 7 includes a support frame 71 and two clamping plates 73 slidably installed on both sides of the bottom of the support frame 71. A second bidirectional cylinder 72 is installed at both ends of the support frame 71. The output shafts at both ends of the second bidirectional cylinder 72 are fixedly connected to the clamping plates 73 on both sides. The two clamping plates 73 are driven to move closer to each other to grip the mold by the second bidirectional cylinder 72 on both sides. At the same time, an ejection cylinder 74 is installed on the inner wall of the two clamping plates 73. The two ejection cylinders 74 are arranged diagonally, which can improve the ejection effect of the lower mold. A pneumatic hammer 75 is installed in the middle of the bottom end of the support frame 71. The ejection cylinder 74 is used to push the lower mold of the mold to separate the lower mold from the overall mold. The pneumatic hammer 75 is used to hammer the upper mold after the lower mold is separated to make it vibrate and separate the cement counterweight block from the upper mold. The finished product palletizing area is equipped with a palletizing platform 9. The palletizing grippers 10 grab the counterweights that have passed the quality inspection and transfer them to the palletizing platform 9 for stacking. The palletizing gripper 10 includes a second connecting seat 101 and a third bidirectional cylinder 102 installed at the bottom of the second connecting seat 101. A rotating seat is provided between the second connecting seat 101 and the third bidirectional cylinder 102. The third bidirectional cylinder 102 is fixedly connected to the rotating seat. A rotary motor is installed on the second connecting seat 101 to drive the rotating seat to rotate circumferentially. The rotary motor can drive the third bidirectional cylinder 102 to rotate circumferentially. A contouring gripper 103 is installed on the output shafts at both ends of the third bidirectional cylinder 102. The gripping position of the contouring gripper 103 can be finely adjusted circumferentially. The contouring gripper 103 adapts to irregular cement counterweights, thereby improving the gripping strength of the counterweights. After gripping the counterweights, the moving mechanism 3 transfers the counterweights to the palletizing platform 9 for stacking.

[0020] In this embodiment, the mold is placed in the mold-taking frame 4 by a forklift (the mold is set vertically at this time for easy gripping). The 3D camera 35 takes a picture of the mold to determine its position. After the position is determined, the moving mechanism 3 drives the mold-taking claw 5 to move to the mold. At this time, the mold is first laid down by the movement of the tilting cylinder 56. Then, the first bidirectional cylinder 54 drives the two finger plates 55 to move closer to each other to grip the mold. After gripping, the moving mechanism 3 moves the mold to the top of the transfer platform 61. At this time, the first servo motor 53 drives the rotating base plate 52 to rotate slowly, and then places the mold flat on the transfer platform 61. After the mold is positioned on the transfer platform 61, the moving mechanism 3 drives the mold removal gripper 7 to rotate the mold and move it above the conveyor belt 62 on one side. At this time, the lower mold is pushed by the telescopic end of the ejector cylinder 74, causing the lower mold to fall onto the conveyor belt 62 for removal. During the falling process, the first detection sensor 63 determines whether the lower mold and cement block have fallen off. After the lower mold falls off, the moving mechanism 3 drives the upper mold and counterweight to move above the detection platform 8. At this time, the pneumatic hammer 75 vibrates the upper mold, thereby disassembling the counterweight and causing it to fall onto the tilting platform 86. The counterweight that falls onto the tilting table 86 is clamped and fixed by the clamping cylinder 88 driving the pressing rod 810 to move. The second servo motor 83 drives the rotating shaft 82 and the tilting table 86 to rotate, flipping the counterweight and placing it on the fixed table 84. During the flipping process, the second detection sensor 85 detects the surface quality of the counterweight (such as burrs, protrusions, dents, etc.) to determine whether the counterweight is qualified. After the counterweight is disassembled, the moving mechanism 3 finally moves the upper mold to another conveyor belt 62 for the upper mold to be moved. After the counterweight block passes inspection, the moving mechanism 3 drives the palletizing gripper 10 to move above it, and the third bidirectional cylinder 102 drives the contouring gripper 103 to grab the counterweight block. After grabbing, it is transferred to the palletizing table 9 for stacking. Through the cooperation of the mold removal gripper 5, the demolding gripper 7 and the palletizing gripper 10, the demolding and palletizing process of the washing machine counterweight block is realized, which greatly reduces the workload of workers and eliminates the need for manual operation of heavy objects, thus meeting the needs of large-scale production.
