Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, specifically to an oil filter element component and its processing method. Background Technology

[0002] An automotive oil filter consists of two end caps, filter paper, and a mesh cylinder. During installation, the filter paper is rolled into a cylinder and inserted into the mesh cylinder, and an end cap is glued to both ends of the mesh cylinder.

[0003] Patent document CN114753185A discloses a processing equipment for automotive air filter elements, specifically relating to the field of automotive parts processing. The equipment includes a bracket and a motor, with the motor mounted on the bracket and connected to a drive mechanism. One side of the drive mechanism is equipped with a first gluing mechanism, a second gluing mechanism, and a pushing mechanism. The first gluing mechanism is located on one side of the pushing mechanism, and a feeding mechanism is positioned above it. By controlling the pushing mechanism, two end caps and filter paper and a mesh cylinder located between them are pushed together. Then, the second gluing mechanism applies gluing to the filter paper and mesh cylinder, increasing the connection stability between them. The assembled filter is then removed, and the second gluing mechanism triggers the feeding mechanism, which lowers the matching mesh cylinder, filter paper, and two end caps to the workstation. Repeating this process allows for the continuous processing of batches of filters, improving processing efficiency.

[0004] The above-mentioned device has the following shortcomings: it cannot accurately align the top cover and filter paper tube for gluing and assembly, which easily leads to misalignment and disordered assembly. In addition, the adjustment steps of the above-mentioned device are cumbersome, requiring precise calculation of gear ratio and wheel diameter ratio, which is inconvenient to use, inconvenient for loading and unloading, and has low work efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems and deficiencies by providing an oil filter element component and its processing method, thereby improving overall work efficiency.

[0006] The technical problem solved by this invention is:

[0007] (1) The above device cannot accurately align the top cover and filter paper tube for gluing and assembly during use, and cannot be assembled in an orderly manner;

[0008] (2) The above-mentioned device has complicated adjustment steps, is inconvenient to use, is inconvenient to load and unload materials, and has low work efficiency.

[0009] The objective of this invention can be achieved through the following technical solution: an oil filter element component, comprising an upper top cover, a lower top cover on one side of the upper top cover, and the upper and lower top covers being arranged opposite each other. An upper spring is installed on the opposite side of the upper and lower top covers, and a lower spring is installed on the opposite side of the lower top cover. A filter element paper tube is provided between the upper and lower top covers, and a central connecting pipe is sleeved in the middle of the filter element paper tube. The central connecting pipe is fixedly snapped to the upper and lower top covers respectively, and the central connecting pipe is sleeved on the outside of the upper and lower springs respectively. The two ends of the filter element paper tube are fixedly connected to the upper and lower top covers respectively by glue.

[0010] A method for processing an oil filter element component, the method comprising the following steps:

[0011] Step 1: Assemble the filter element components of the oil filter using the processing device. Place the upper top cover on the first placement frame of the rotary conveyor belt, place the filter paper tube on the second placement frame, and place the lower top cover on the third placement frame. At the same time, connect the upper spring to the upper top cover and the lower spring to the lower top cover. Insert the middle pipe into the filter paper tube, and then start the processing device to assemble.

[0012] Step 2: Apply glue to the inner rings of the upper and lower top covers simultaneously using the glue application assembly on the first placement platform. The upper and lower top covers are transported sequentially to the area directly below the glue application assembly via a rotary conveyor belt. Then, the glue application assembly is lowered by a lifting push rod and glue is applied through the glue application assembly.

[0013] Step 3: Move the top and bottom covers with glue applied and the filter paper tube to one side of the second placement platform by the rotary conveyor belt. Move the clamping cylinder by the first dual-axis slide to move the filter paper tube and its inner middle tube to the top cover, so that the middle tube is engaged with the middle of the top cover and the filter paper tube is wetted and abutted against the glue on the top cover.

[0014] Step 4: The first placement frame, containing the filter paper tube and the top cover, is moved to the underside of the mounting frame via a rotary conveyor belt. Then, the mounting frame is moved by the second dual-axis slide of the third placement platform. The top cover and filter paper tube are clamped by a pair of support crossbars on the mounting frame. The top cover and filter paper tube are then rotated 180 degrees by a rotary motor so that the top cover is on top. The mounting frame is then moved by the second dual-axis slide to align the top cover and filter paper tube with the bottom cover, completing one assembly.

[0015] Step 5: The first placement rack, the second placement rack, and the third placement rack are sequentially transported by a rotary conveyor belt. The above steps are repeated to assemble each set of filter elements in a cyclical manner.

[0016] As a further aspect of the invention, in step two, the glue-applying motor of the glue-applying assembly drives the telescopic support rods on itself and the support column to rotate synchronously, so that the second support rod maintains horizontal reciprocating motion, and the two glue-applying tubes on the support slide rod draw circles with the center of the upper cover and the center of the lower cover as the axis and the length of the telescopic support rod as the radius, so as to evenly pour glue into the annular grooves of the upper cover and the lower cover.

[0017] As a further aspect of the invention, in step three, air is pressurized by an air pump, and the air distribution pipe inside the clamping cylinder is connected through the air distribution pipe. The air distribution pipe is connected to each air branch pipe, and the air branch pipe is connected to the first clamping tube and the second clamping tube, so that the first clamping tube and the second clamping tube are inflated and expanded. The first clamping tube clamps the outer periphery of the filter paper tube in an annular manner, and the second clamping tube clamps the inner side of the central tube in an annular manner.

[0018] As a further aspect of the invention, in step four, the support crossbar is moved synchronously by two opposing single-axis slides mounted on the mounting plate. The upper cover and filter paper tube are clamped by the clamping plates on the clamping vertical rod. The spring rod is adapted to the diameter of the upper cover and filter paper tube to maintain stable clamping. Then, the rotating motor rotates the mounting plate, causing the upper cover and filter paper tube, which are clamped by the single-axis slides and clamping plates, to rotate relative to the lower cover and lower spring.

[0019] The beneficial effects of this invention are:

[0020] (1) The glue application motor of the glue application assembly drives the telescopic support rods on itself and the support column to rotate synchronously, so that the second support rod maintains horizontal reciprocating motion, so that the two glue application tubes on the support slide rod draw circles with the center of the upper cover and the center of the lower cover as the axis and the length of the telescopic support rod as the radius, and evenly pour glue into the annular grooves of the upper cover and the lower cover. Adjust the length of the telescopic support rod according to the different diameters and glue application positions of the upper cover and the lower cover, so as to adapt to different upper cover and lower cover. Adjust the spacing and number of support slides according to the different spacing of the upper cover and the lower cover, so as to adapt to different assembly production lines.

[0021] (2) The air guide tube is connected to the air guide branch tube inside the clamping cylinder through the air guide tube, and the air guide branch tube is connected to the first clamping rubber tube and the second clamping rubber tube through the air guide branch tube, so that the first clamping rubber tube and the second clamping rubber tube are inflated and expanded. The first clamping rubber tube clamps the outer periphery of the filter paper tube in an annular manner, and the second clamping rubber tube clamps the inner side of the middle tube in an annular manner, thereby moving the filter paper tube and the middle tube to the top cover and the upper spring at the same time to prevent the middle tube from falling off. At the same time, it is also to prevent the outer periphery of the filter paper tube from deforming due to the small number of clamping points. During clamping, the middle tube is clamped by the filter paper tube and moves synchronously. With the support of the top cover, the middle tube and the upper spring, the filter paper tube is prevented from deforming and the middle tube is prevented from falling off.

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] Please see Figure 1-7 As shown: A filter element component for an oil filter includes an upper cover 101, a lower cover 106 on one side of the upper cover 101, and the upper cover 101 and the lower cover 106 are arranged opposite to each other. An upper spring 102 is installed on the opposite side of the upper cover 101 and the lower cover 106, and a lower spring 105 is installed on the opposite side of the lower cover 106. A filter element paper tube 103 is provided between the upper cover 101 and the lower cover 106. A middle connecting pipe 104 is sleeved in the middle of the filter element paper tube 103. The middle connecting pipe 104 is fixedly snapped to the upper cover 101 and the lower cover 106 respectively, and the middle connecting pipe 104 is sleeved on the outside of the upper spring 102 and the lower spring 105 respectively. The two ends of the filter element paper tube 103 are fixedly connected to the upper cover 101 and the lower cover 106 respectively by glue.

[0033] A method for processing an oil filter element component, the method comprising the following steps:

[0034] Step 1: Assemble the filter element components of the oil filter using the processing device. Place the upper top cover 101 on the first placement frame 2 of the rotary conveyor belt 1, place the filter element paper tube 103 on the second placement frame 3, and place the lower top cover 106 on the third placement frame 4. At the same time, connect the upper spring 102 to the upper top cover 101 and the lower spring 105 to the lower top cover 106. Insert the middle connecting pipe 104 into the filter element paper tube 103, and then start the processing device to assemble.

[0035] Step 2: Apply glue to the inner rings of the upper top cover 101 and the lower top cover 106 simultaneously using the glue application assembly 11 on the first placement platform 5. The upper top cover 101 and the lower top cover 106 are transported sequentially to the area directly below the glue application assembly 11 by the rotary conveyor belt 1. Then, the glue application assembly 11 is lowered by the lifting push rod 8 and glue is applied through the glue application assembly 11.

[0036] Step 3: Move the glue-coated upper cover 101, lower cover 106, and filter paper tube 103 to one side of the second placement platform 6 via the rotary conveyor belt 1. Move the clamping cylinder 13 via the first dual-axis slide table 9 to move the filter paper tube 103 and its inner middle tube 104 onto the upper cover 101, so that the middle tube 104 is engaged with the middle of the upper cover 101, and the filter paper tube 103 is wetted and abutted against the glue on the upper cover 101.

[0037] Step 4: The first placement frame 2, containing the filter paper tube 103 and the upper cover 101, is moved to the underside of the mounting frame 14 by the rotary conveyor belt 1. Then, the mounting frame 14 is moved by the second dual-axis slide 10 of the third placement platform 7. The upper cover 101 and the filter paper tube 103 are clamped by a pair of support crossbars 17 on the mounting frame 14. Then, the upper cover 101 and the filter paper tube 103 are rotated 180 degrees by the rotary motor 15 so that the upper cover 101 is on top. Then, the mounting frame 14 is moved by the second dual-axis slide 10 to connect the upper cover 101 and the filter paper tube 103 to the lower cover 106, completing one assembly.

[0038] Step 5: The first placement rack 2, the second placement rack 3 and the third placement rack 4 are sequentially transported by the rotary conveyor belt 1. The above steps are repeated to assemble each set of filter elements in a cyclical manner.

[0039] In step two, the glue application motor 20 of the glue application assembly 11 drives the telescopic support rod 23 on itself and the support column 22 to rotate synchronously, so that the second support rod 24 maintains horizontal reciprocating motion. This causes the two glue application tubes 28 on the support slide rod 25 to draw circles with the center of the upper cover 101 and the center of the lower cover 106 as the axis and the length of the telescopic support rod 23 as the radius, so that glue is evenly poured into the annular grooves of the upper cover 101 and the lower cover 106. The glue pump 19 and the glue guide tube 29 guide the glue evenly and fully to the glue application tube head 28, so that the glue is poured in at the same rate and in the same amount, preventing over- or under-pour. The length of the telescopic support rod 23 is adjusted according to the different diameters of the upper top cover 101 and the lower top cover 106 and the glue application position, so as to adapt to different upper top cover 101 and lower top cover 106. The spacing and number of the support sleeves 26 are adjusted according to the different spacing of the upper top cover 101 and the lower top cover 106, so as to adapt to different assembly production lines.

[0040] In step three, the air pump 12 pressurizes the air, and the air guide pipe 18 connects to the air guide branch pipe 30 inside the clamping cylinder 13. The air guide branch pipe 30 connects to each air guide branch pipe 33, and the air guide branch pipe 33 connects to the first clamping rubber tube 32 on the inner side wall of the clamping cylinder 13 and the second clamping rubber tube 34 on the outer side wall of the mounting column 31. This causes the first clamping rubber tube 32 and the second clamping rubber tube 34 to inflate and expand. The first clamping rubber tube 32 clamps the outer periphery of the filter paper tube 103 in an annular manner, and the second clamping rubber tube 34 clamps the inner side of the middle pipe 104 in an annular manner. This simultaneously moves the filter paper tube 103 and the middle pipe 104 onto the upper top cover 101 and the upper spring 102, preventing the middle pipe 104 from falling off and avoiding deformation of the outer periphery of the filter paper tube 103 due to insufficient clamping points.

[0041] In step four, the two opposing single-axis slides 16 mounted on the mounting plate 36 move the support crossbar 17 synchronously. The clamping plates 37 on the clamping vertical bar 35 clamp the upper cover 101 and the filter paper tube 103. The spring rod 38 is adapted to the diameter of the upper cover 101 and the filter paper tube 103 to maintain stable clamping. Then, the rotary motor 15 rotates the mounting plate 36, causing the upper cover 101 and the filter paper tube 103, which are clamped by the single-axis slides 16 and the clamping plates 37, to rotate so that they can be vertically and accurately aligned with the lower cover 106 and the lower spring 105. At the same time, during clamping, the middle pipe 104 is clamped by the filter paper tube 103 and moves synchronously. With the support of the upper cover 101, the middle pipe 104 and the upper spring 102, the filter paper tube 103 is prevented from deforming, and the middle pipe 104 is prevented from falling off.

[0042] The processing device includes a rotary conveyor belt 1, on which several sets of placement racks are installed side by side. Each set of placement racks includes a first placement rack 2, a second placement rack 3 and a third placement rack 4. A first placement table 5, a second placement table 6 and a third placement table 7 are installed sequentially on one side of the rotary conveyor belt 1.

The second placement platform 6 is equipped with a first dual-axis slide 9 and an air pump 12. The third placement platform 7 is equipped with a second dual-axis slide 10. A clamping cylinder 13 is mounted on the lower side of the moving end of the first dual-axis slide 9. A mounting frame 14 is mounted on the lower side of the moving end of the second dual-axis slide 10. The mounting frame 14 has an L-shaped structure. A rotary motor 15 is mounted on one side of the lower end of the mounting frame 14. A mounting plate 36 is mounted on one end of the drive shaft of the rotary motor 15. The middle of the mounting plate 36... Two symmetrically arranged single-axis slides 16 are installed on the side wall of the mounting plate 36, which is fixedly connected to the drive shaft of the rotary motor 15. Supporting crossbars 17 are fixedly connected to the sliders of the two single-axis slides 16. Clamping vertical bars 35 are fixedly connected to the middle of the opposite side of the two supporting crossbars 17. The middle of the clamping vertical bars 35 is fixedly connected to the middle of the supporting crossbars 17. Several clamping plates 37 are evenly distributed at equal intervals on the opposite side of the two clamping vertical bars 35. The clamping plates 37 are arc-shaped and connected to the clamping vertical bars 35 by spring bars 38.

[0044] The adhesive application assembly 11 includes an adhesive application motor 20, which is vertically mounted on a lifting push rod 8. A first support rod 21 is fixedly connected to one side of the adhesive application motor 20. A support column 22 is fixedly connected to the top of one end of the first support rod 21. Telescopic support rods 23 are rotatably connected to the upper part of the support column 22 and the upper end of the drive shaft of the adhesive application motor 20. A second support rod 24 is rotatably connected to both the two telescopic support rods 23. The length of the second support rod 24 is the same as the distance between the support column 22 and the drive shaft of the adhesive application motor 20, and the second support rod 24 is parallel to the first support rod 21. The retractable support rods 23 are kept to be of equal length and parallel. The second support rod 24 is fixedly connected to a support slide rod 25 at one end near the rotary conveyor belt 1. A support slide sleeve 26 is slidably sleeved on the support slide rod 25. A positioning bolt for abutment and positioning is threaded through the support slide sleeve 26. An installation tube sleeve 27 is fixedly connected to one side of the support slide sleeve 26. An adhesive applicator head 28 is installed on the support slide sleeve 26 through the installation tube sleeve 27. The two adhesive applicator heads 28 are respectively connected to the glue pump 19 through the glue guide tube 29. The two adhesive applicator heads 28 correspond one-to-one with the first placement frame 2 and the third placement frame 4.

[0045] The clamping cylinder 13 has an open bottom structure. An installation post 31 is installed in the middle of the inner side of the clamping cylinder 13. Several first clamping tubes 32 are evenly distributed at equal intervals on the inner side wall of the clamping cylinder 13. Several second clamping tubes 34 are evenly distributed at equal intervals on the outer side wall of the installation post 31. Both the clamping cylinder 13 and the installation post 31 have air guide branches 33 that connect each of the first clamping tubes 32 and the second clamping tubes 34. An air guide diversion pipe 30 is opened in the top of the clamping cylinder 13 and is connected to each of the air guide branches 33. The air guide diversion pipe 30 is connected to the air pump 12 through the air guide pipe 18. When the cylinder is full of air, the first clamping tubes 32 clamp the filter paper tube 103 in a circular shape, and the outer circumference of the second clamping tubes 34 pushes the central pipe 104 in a circular shape.

[0046] In use, the operator drives the telescopic support rod 23 on the glue application assembly 11 and the support column 22 to rotate synchronously via the glue application motor 20. This causes the second support rod 24 to maintain horizontal reciprocating motion, and the two glue application tubes 28 on the support slide rod 25 to draw circles with the center of the upper cover 101 and the center of the lower cover 106 as the axis and the length of the telescopic support rod 23 as the radius. Glue is evenly poured into the annular grooves of the upper cover 101 and the lower cover 106. The length of the telescopic support rod 23 is adjusted according to the different diameters and glue application positions of the upper cover 101 and the lower cover 106 to adapt to different upper cover 101 and lower cover 106. The spacing and number of the support slide sleeves 26 are adjusted according to the different spacings of the upper cover 101 and the lower cover 106 to adapt to different assembly production lines.

[0047] The air guide tube 18 connects to the air guide branch tube 30 inside the clamping cylinder 13, and the air guide branch tube 30 connects to each air guide branch tube 33. The air guide branch tubes 33 connect to the first clamping rubber tube 32 and the second clamping rubber tube 34, causing the first clamping rubber tube 32 and the second clamping rubber tube 34 to inflate. The first clamping rubber tube 32 clamps the outer periphery of the filter paper tube 103 in an annular manner, and the second clamping rubber tube 34 clamps the inner side of the central tube 104 in an annular manner. The filter paper tube 103 and the middle connecting pipe 104 are moved synchronously onto the top cover 101 and the upper spring 102 to prevent the middle connecting pipe 104 from falling off. At the same time, it is also to prevent the outer periphery of the filter paper tube 103 from deforming due to the limited number of clamping points. During clamping, the middle connecting pipe 104 is clamped by the filter paper tube 103 and moves synchronously. With the support of the top cover 101, the middle connecting pipe 104 and the upper spring 102, the filter paper tube 103 is prevented from deforming, and the middle connecting pipe 104 is also prevented from falling off.

The air guide branch pipe (33) of the hose (34) has an air guide branch pipe (30) inside the top of the clamping cylinder (13) that is connected to each air guide branch pipe (33). The air guide branch pipe (30) is connected to the air pump (12) through the air guide pipe (18). The air pump (12) pressurizes the first clamping hose (32) and the second clamping hose (34) to expand. The first clamping hose (32) clamps the outer periphery of the filter paper tube (103) in an annular manner, and the second clamping hose (34) clamps the inner side of the middle tube (104) in an annular manner. The filter paper tube (103) and the middle tube (104) inside it are moved synchronously to the top cover (101) and the upper spring (102). Step 4: The first placement frame (2) containing the filter paper tube (103) and the top cover (101) is moved to the position directly below the mounting frame (14) by the rotary conveyor belt (1); the mounting frame (14) is moved by the second dual-axis slide (10), wherein the two oppositely arranged single-axis slides (16) mounted on the mounting plate (36) move the support crossbar (17) synchronously, and the clamping plates (37) on the clamping vertical bar (35) clamp the top cover (101) and the filter paper tube (103). The spring rod (38) is adapted to the diameter of the top cover (101) and the filter paper tube (103) to maintain stable clamping; then the rotary motor (15) rotates the mounting plate (36), which drives the top cover (101) and the filter paper tube (103) clamped by the single-axis slide (16) and the clamping plate (37) to rotate, so that they are opposite to the bottom cover (106) and the bottom spring (105), and the top cover (101) and the filter paper tube (103) are connected to the bottom cover (106) to complete one assembly; Step 5: The first placement rack (2), the second placement rack (3) and the third placement rack (4) are sequentially transported by the rotary conveyor belt (1). The above steps are repeated to assemble each set of filter elements in a cyclical manner.
