Description

Technical Field

[0001] This invention relates to the field of automatic filter assembly technology, and more specifically, to an automatic filter assembly machine. Background Technology

[0002] A filter is a device used to filter impurities from fluids such as air, oil, and water. A filter generally consists of a filter element, an upper cover, and a lower cover. Its main classifications include air filters, oil filters, and fuel filters. Automatic filter assembly refers to the entire process of automatically feeding, positioning, assembling, testing, and unloading filter components (such as the housing, sealing rings, filter element, and overflow valve) using automated equipment, control systems, and sensor technology.

[0003] When the flipping device flips the filter element, if the glue inside the top cover is not completely dry, the inertia during the flipping process may cause the top cover to detach from or tilt on the filter element, which may damage the filter element when it is placed. At the same time, when the first turntable in the lower cover assembly mechanism works for a long time, it may cause a small cumulative error to occur on the first turntable, causing the lower cover on the first support plate to be misaligned with the filter element. If it is then assembled, it will damage the filter element and also affect the working efficiency of subsequent equipment.

[0004] This invention provides an automatic filter assembly machine, which aims to solve the problems that, on the one hand, when the flipping device flips the filter element, the upper cover will detach from the filter element due to inertia, and on the other hand, when the first turntable works for a long time, a small cumulative error will occur on the first turntable, causing the lower cover on the first support plate to be misaligned with the filter element. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic filter assembly machine to solve the problems mentioned in the background art, namely, that when the flipping device flips the filter element, the upper cover will detach from the filter element due to inertia, and that when the first turntable works for a long time, a small cumulative error will occur on the first turntable, causing the lower cover on the first support plate to be misaligned with the filter element.

The gripping arm slides within the contoured grooves, and a sliding block is fixedly connected to the arc-shaped side of the gripping arm. The sliding block slides in a sealed manner within the connecting channel. A second elastic element is connected between the inner wall of the gas storage chamber and the sliding block, and the gas storage chamber is filled with gas.

[0010] Preferably, both the left and right grippers are provided with multiple guide components, each guide component including a fixed block. The fixed block has a movable groove, and a fixed rod and two first limiting posts are fixedly connected in the movable groove. A guide claw is rotatably connected to the fixed rod, and the same number of second limiting posts as the first limiting posts are fixedly connected to both sides of the guide claw. Both sides of the guide claw are provided with torsion springs and sleeved on the fixed rod, and both ends of each torsion spring are in contact with the first and second limiting posts.

[0011] Preferably, a connecting post is fixedly connected to one end of the fixed block away from the guide claw, and a piston plate is fixedly connected to the other end of the connecting post.

Each sliding groove is provided with a partition, each partition is provided with a connecting hole, and each sliding groove is provided with a vent hole between it and the gas storage chamber.

[0012] Preferably, the piston plate is slidably connected in the sliding groove and located between the sliding groove and the partition plate, the connecting column is sealed and slidably on the communicating hole, and a third elastic element is connected between the sliding groove and the piston plate.

[0013] Preferably, the lower cover assembly mechanism includes a first turntable, on which multiple sets of first support plates are distributed equidistantly along the circumference are provided. Each first support plate is provided with a wedge-shaped groove that is the same number and position as the guide claws. A lower cover feeding mechanism is provided on one side of the first turntable, a first compaction mechanism is provided on the other side of the first turntable, and a pushing mechanism is provided on the side of the first turntable away from the flipping mechanism. The upper cover assembly mechanism includes a second turntable, which is provided with multiple sets of second support plates distributed equidistantly along the circumference. Each second support plate is provided with a positioning component. An upper cover feeding mechanism is provided on one side of the second turntable, and a second compaction mechanism is provided on the other side of the second turntable.

[0014] Preferably, the body is provided with a filter element feeding mechanism on the side near the top cover assembly mechanism. The filter element feeding mechanism includes a feeding conveyor line, a frame for placing and conveying filter elements is provided on the feeding conveyor line, and a feeding clamping mechanism for moving filter elements to the second support plate in the top cover assembly mechanism is provided above the feeding conveyor line.

[0015] Preferably, the machine body is provided with a finished product unloading mechanism on the side near the lower cover assembly mechanism. The finished product unloading mechanism includes an unloading conveyor line, and a feeding mechanism for pushing the filter unloading is provided above the unloading conveyor line.

[0016] The technical effects and advantages of this invention are as follows: 1. By setting the limiting component, when the clamping component clamps the filter element, the guide post will push the guide cap to rotate the limiting plate. While clamping the filter element, the surface of the limiting plate will contact and limit the bottom of the top cover, thereby preventing the risk of the top cover falling off due to inertia when the flipping component flips, thus improving the filter yield and the working efficiency of the equipment. 2. By setting the clamping components, when the left and right jaws clamp the filter element, the outer wall of the filter element will first contact the clamping arms, causing the clamping arms to slide and compress the gas in the gas storage chamber, and the sliding block to compress the gas in the gas storage chamber, causing the second elastic element to rebound. This allows the clamping arms to buffer when clamping the filter element. After the filter element is placed in place, the left and right jaws move away from each other, and the compressed gas rebounds, causing the clamping arms to return to their original shape. This prevents the clamping components from being too tight or too loose when clamping the filter element, and improves the assembly efficiency of the filter. 3. By setting up the guide assembly, on the one hand, when assembling the filter element and the lower cover, the wedge groove on the first support plate guides the guide claw, allowing the guide claw to slide along the slope of the wedge groove and clamp the lower cover, keeping the lower cover and the filter element concentric. On the other hand, by lowering the left and right claws again, the guide claw pushes the piston plate to slide in the sliding groove and compress the third elastic element, thereby creating negative pressure in the vent hole. This allows the gas in the gas storage chamber to enter the sliding groove through the vent hole. When the sliding block does not have enough gas to compress it, the stretched second elastic element will rebound and drive the clamping arm to move, causing the clamping arm to release the clamping arm from the filter element, allowing the filter element to fall into the lower cover. This prevents damage to the outer wall of the filter element when it is pressed down, improving the assembly accuracy and working efficiency of the filter element and the lower cover.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 When the flipping device flips the filter element, the glue inside the cover may not be completely dry. Due to inertia, the cover may detach from the filter element or tilt during the flipping process, which may damage the filter element when it is placed.

[0021] refer to Figure 1 and Figure 2 An automatic filter assembly machine according to an embodiment of the present invention includes a machine body 1, an upper cover assembly mechanism 11 and a lower cover assembly mechanism 12 are provided inside the machine body 1, and a flipping mechanism 13 is provided between the upper cover assembly mechanism 11 and the lower cover assembly mechanism 12.

[0022] refer to Figure 5and Figure 6 The flipping mechanism 13 includes two guide rods 131 fixed on the table surface of the machine body 1. The other end of the two guide rods 131 is fixedly connected to a connecting plate 132. A transmission component 2 is provided on the side of the connecting plate 132 away from the guide rods 131. A lifting component 3 is provided on the other side of the connecting plate 132. A flipping component 4 is provided on the lifting component 3. A clamping component 5 is provided on the flipping component 4 in a symmetrical arrangement.

[0023] The movement of the transmission component 2 causes the lifting component 3 to rise or fall. After reaching the designated position, the flipping component 4 drives the clamping component 5 to flip, thereby enabling the clamping component 5 to grab and assemble the filter element.

[0024] refer to Figure 6 and Figure 7 The gripping component 5 includes a slide table 51, on which two sliders 52 are slidably connected. Each slider 52 is fixedly connected to a fixing plate 53. Each fixing plate 53 has a left gripper 54 and a right gripper 55 fixedly connected to its corresponding side. The left gripper 54 and the right gripper 55 are symmetrically arranged, and a limiting component 6 is provided between the left gripper 54 and the right gripper 55.

[0025] refer to Figures 7 to 11 The limiting component 6 includes a rotating column 61 rotatably connected to the side of the left gripper 54 away from the fixed plate 53. A pressing groove 62 is provided inside the rotating column 61. A limiting plate 63 is fixedly connected to the outer wall of the rotating column 61. An arc-shaped groove 64 is provided on the inner wall of the rotating column 61. A guide cap 65 is slidably connected inside the rotating column 61. A fixed column 66 is fixedly connected to the outer wall of the guide cap 65. The fixed column 66 slides along the arc-shaped groove 64. A guide groove 67 is provided on the inner wall of the guide cap 65. The guide groove 67 is inclined near the opening of the guide cap 65 to facilitate the insertion of the guide block 69. A guide column 68 is fixedly connected to the side of the right gripper 55 away from the fixed plate 53. A guide block 69 is fixedly connected to the outer wall of the guide column 68. The guide block 69 is slidably connected in the guide groove 67. A first elastic element 610 is connected between the pressing groove 62 and the guide cap 65. A pressure sensor 611 is provided on the end of the limiting plate 63 away from the rotating column 61.

[0026] It should be noted that when there is an error in the length of the filter element, because the lifting assembly 3 has a consistent stroke, it is impossible to determine whether the filter element is assembled in place when it is assembled with the lower cover. However, by setting a pressure sensor 611, when the filter element is assembled in place, the filter element will generate a reaction force that the pressure sensor 611 can sense, thereby stopping the descent of the lifting assembly 3 and preventing the risk of filter element deformation.

[0027] By setting the limiting component 6, when the clamping component 5 clamps the filter element, the left clamping claw 54 and the right clamping claw 55 will move closer to the filter element. At the same time, the guide post 68 on the right clamping claw 55 will be inserted into the guide cap 65, and the guide block 69 will slide in the guide groove 67. When the guide post 68 is inserted to the bottom of the guide cap 65, it will push the guide cap 65 to slide in the pressing groove 62 and compress the first elastic element 610. The fixing post 66 on the outer wall of the guide cap 65 will slide along the arc groove 64 to make the guide cap 65 rotate. At the same time, it will drive the limiting plate 63 to rotate slowly. While clamping the filter element, the surface of the limiting plate 63 will contact the bottom of the top cover and limit it, preventing the risk of the top cover falling off due to inertia when flipping.

[0028] refer to Figure 2 and Figure 3 The lower cover assembly mechanism 12 includes a first turntable 121, on which multiple sets of first support plates 122 are distributed equidistantly along the circumference. Each first support plate 122 has a wedge-shaped groove 123 with the same number and position as the guide claws 85. A lower cover feeding mechanism 124 is provided on one side of the first turntable 121, and a first compaction mechanism 125 is provided on the other side of the first turntable 121. A pushing mechanism 126 is provided on the side of the first turntable 121 away from the flipping mechanism 13. The upper cover assembly mechanism 11 includes a second turntable 111, on which multiple sets of second support plates 112 are distributed equidistantly along the circumference. Each second support plate 112 has a positioning component 113. An upper cover feeding mechanism 114 is provided on one side of the second turntable 111, and a second compaction mechanism 115 is provided on the other side of the second turntable 111.

[0029] refer to Figure 1 and Figure 2 The machine body 1 is provided with a filter element feeding mechanism 14 on the side near the upper cover assembly mechanism 11. The filter element feeding mechanism 14 includes a feeding conveyor line 141. A frame 142 for placing and conveying filter elements is provided on the feeding conveyor line 141. A feeding clamping mechanism 143 for moving filter elements to the second support plate 112 in the upper cover assembly mechanism 11 is provided above the feeding conveyor line 141.

[0030] refer to Figure 1 and Figure 2 The machine body 1 is provided with a finished product unloading mechanism 15 on the side near the lower cover assembly mechanism 12. The finished product unloading mechanism 15 includes an unloading conveyor line 151, and a feeding mechanism 152 for pushing the filter unloading is provided above the unloading conveyor line 151.

[0031] The upper cover assembly mechanism 11, the lower cover assembly mechanism 12, the filter element feeding mechanism 14, and the finished product unloading mechanism 15 are all existing technologies and will not be described in detail here.

[0032] In actual use, after the filter element and the top cover are assembled by the top cover assembly mechanism 11, the filter element is moved to the designated position by the rotation of the first turntable 121. Then, the transmission component 2 in the flipping mechanism 13 is activated, which causes the lifting component 3 to descend, so that the left jaw 54 and the right jaw 55 of the clamping component 5 are located on both sides of the filter element. Then, the slide table 51 is activated, controlling the left jaw 54 and the right jaw 55 to move towards the center. At the same time, the guide post 68 on the right jaw 55 is inserted into the guide cap 65, and the guide block 69 slides in the guide groove 67. When the guide post 68 is inserted to the bottom of the guide cap 65, it pushes the guide cap 65 to slide in the pressing groove 62 and compresses the first elastic element 610. The fixing post 66 on the outer wall of the guide cap 65 slides along the arc groove 64, causing the guide cap 65 to rotate. At the same time, the limiting plate 63 will slowly rotate, clamping the filter element while the surface of the limiting plate 63 contacts and limits the bottom of the upper cover. At this time, the positioning component 113 releases the limit on the upper cover, and the transmission component 2 controls the lifting component 3 to rise. When it reaches the specified height, the flipping component 4 drives the clamping component 5 to flip. After the flipping is completed, the transmission component 2 controls the lifting component 3 to descend, so that the filter element is inserted into the lower cover. At this time, the slide table 51 controls the left clamp 54 and the right clamp 55 to open, and at the same time, the guide post 68 will move with the right clamp 55. At this time, the compressed first elastic element 610, without the limit of the guide post 68, will push the guide cap 65 to move, and at the same time, the limiting plate 63 will flip and move away from the top of the upper cover. Then the lifting component 3 rises and continues the above work.

[0033] It should be noted that the flipping component 4 can only be controlled to flip when the lifting component 3 rises to a specified height; otherwise, the limit plate 63 will cause interference.

[0034] In summary, by setting the limiting component 6, when the clamping component 5 clamps the filter element, the guide post 68 pushes the guide cap 65 to rotate the limiting plate 63. While clamping the filter element, the surface of the limiting plate 63 contacts and limits the bottom of the upper cover, thereby preventing the risk of the upper cover falling off due to inertia when the flipping component 4 flips, thus improving the filter yield and the working efficiency of the equipment.

[0035] Example 2 When the gripper picks up and flips the filter element, the inner diameter of the gripper remains unchanged. If the gripper is too tight, the filter element will be damaged. If the gripper is too loose, the filter element may fall out of the gripper, thus affecting the assembly efficiency of the filter. Therefore, this embodiment improves the device described in the above embodiment.

[0036] refer to Figure 6 , Figure 12 and Figure 13Both the left gripper 54 and the right gripper 55 are equipped with a clamping assembly 7, which includes a clamping arm 71. Both the left gripper 54 and the right gripper 55 have a contour groove 72 and a gas storage chamber 73. A connecting channel 74 is provided between the contour groove 72 and the gas storage chamber 73. The clamping arm 71 slides in the contour groove 72. The clamping arm 71 is made of a flexible and wear-resistant material, so that the clamping arm 71 plays a buffering role when clamping the filter element. A sliding block 75 is fixedly connected to the arc-shaped side of the clamping arm 71. The sliding block 75 slides in a sealed manner in the connecting channel 74. A second elastic element 76 is connected between the inner wall of the gas storage chamber 73 and the sliding block 75. The gas storage chamber 73 is filled with gas.

[0037] In actual use, when the left gripper 54 and right gripper 55 clamp the filter element, the outer wall of the filter element will first contact the clamping arm 71, causing the clamping arm 71 to slide within the contour groove 72 and the sliding block 75 to compress the gas in the gas storage chamber 73, causing the second elastic element 76 to rebound. This allows the clamping arm 71 to buffer the filter element during clamping. After the filter element is placed in place, the left gripper 54 and right gripper 55 move away from each other, and the compressed gas rebounds, causing the clamping arm 71 to return to its original shape. This prevents the clamping assembly 5 from being too tight or too loose when clamping the filter element, and improves the assembly efficiency of the filter.

[0038] Example 3 When the first turntable in the lower cover assembly mechanism works for a long time, it will cause a small cumulative error to occur on the first turntable, causing the lower cover on the first support plate to be misaligned with the filter element. If the assembly continues under these circumstances, the filter element will be damaged, and the working efficiency of subsequent equipment will also be affected. Therefore, this embodiment improves the device described in the above embodiment.

[0039] refer to Figure 12 and Figure 14 Both the left gripper 54 and the right gripper 55 are provided with multiple guide components 8. Each guide component 8 includes a fixing block 81. The fixing block 81 has a movable groove 82. A fixing rod 83 and two first limiting posts 84 are fixedly connected in the movable groove 82. A guide claw 85 is rotatably connected to the fixing rod 83. The guide claw 85 has two second limiting posts 86 fixedly connected to both sides, the same number as the first limiting posts 84. Both sides of the guide claw 85 are provided with torsion springs 87 and sleeved on the fixing rod 83. The two ends of each torsion spring 87 are in contact with the first limiting post 84 and the second limiting post 86. Through the setting of the torsion springs 87, the guide claw 85 can automatically spring back to the initial position.

[0040] refer to Figure 12The fixed block 81 is fixedly connected to a connecting post 88 at one end away from the guide claw 85, and a piston plate 89 is fixedly connected to the other end of the connecting post 88. Multiple sliding grooves 810 are provided in the left claw 54 and the right claw 55. The sliding grooves 810 are located on both sides of the gas storage chamber 73. Each sliding groove 810 is provided with a partition 811. Each partition 811 is provided with a connecting hole 812. Each sliding groove 810 is provided with a vent hole 813 between it and the gas storage chamber 73.

[0041] refer to Figure 12 and Figure 14 The piston plate 89 is slidably connected in the sliding groove 810 and located between the sliding groove 810 and the partition plate 811. The connecting column 88 is slidably sealed on the connecting hole 812. A third elastic element 814 is connected between the sliding groove 810 and the piston plate 89.

[0042] refer to Figure 3 and Figure 4 The lower cover assembly mechanism 12 includes a first turntable 121. The first turntable 121 is provided with multiple sets of first support plates 122 distributed equidistantly along the circumference. Each first support plate 122 is provided with wedge-shaped grooves 123 that are the same number and position as the guide claws 85.

[0043] In actual use, when the lifting assembly 3 controls the clamping assembly 5 to descend, one end of the guide claw 85 in the multiple guide assemblies 8 on the left claw 54 and right claw 55 will contact and guide the wedge groove 123 on the first support plate 122, causing the guide claw 85 to slide along the slope of the wedge groove 123 and clamp the lower cover, keeping the lower cover and filter element concentric. At this time, the left claw 54 and right claw 55 will continue to descend, pushing the piston plate 89 to slide in the sliding groove 810 and compress the third elastic element 814. When the piston plate 89 is in the sliding groove 810, it will create negative pressure in the vent hole 813, allowing the gas in the gas storage chamber 73 to enter the sliding groove 810 through the vent hole 813 and be located between the piston plate 89 and the partition plate 811, while the sliding block... 75. Without sufficient gas compression, the stretched second elastic element 76 will rebound and drive the clamping arm 71 to move, causing the clamping arm 71 to loosen its grip on the filter element, allowing the filter element to fall into the lower cover. At this time, the pressure sensor 611 senses and determines whether the clamping is in place by pressing down the limiting component 6. After placement, the left clamping claw 54 and the right clamping claw 55 rise and separate synchronously. The guide claw 85, without the limitation of the wedge groove 123, compresses the third elastic element 814 to rebound and pushes the piston plate 89 to slide, squeezing the gas in the sliding groove 810 into the gas storage chamber 73. When the gas storage chamber 73 is full of gas, it will push the sliding block 75 to move and cause the clamping arm 71 to return to its original state, so that the next batch of filter elements can be clamped.

[0044] In summary, by setting the guide assembly 8, on the one hand, when assembling the filter element and the lower cover, the guide claw 85 can be guided by the wedge groove 123 on the first support plate 122, so that the guide claw 85 slides along the slope of the wedge groove 123 and clamps the lower cover, keeping the lower cover and the filter element concentric. On the other hand, by lowering the left clamp 54 and the right clamp 55 again, the guide claw 85 pushes the piston plate 89 to slide in the sliding groove 810 and compresses the third elastic element 814, thereby creating a negative pressure in the vent hole 813, allowing the gas in the gas storage chamber 73 to enter the sliding groove 810 through the vent hole 813. When the sliding block 75 does not have enough gas to squeeze, the stretched second elastic element 76 will rebound and drive the clamping arm 71 to move, causing the clamping arm 71 to release the clamping of the filter element, so that the filter element falls into the lower cover, thereby preventing damage to the outer wall of the filter element when it is pressed down, and improving the assembly accuracy and working efficiency of the filter element and the lower cover.

[0045] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
