Description

Technical Field

[0001] This invention relates to an improved assembly equipment for automotive electric bridge filters, and more particularly to a filter paper loading mechanism for an electric bridge filter processing equipment. Background Technology

[0002] Automotive power bridge filters are used to filter transmission oil. They mainly consist of a cover plate, filter paper, an upper cover, a lower cover, and a pressure relief valve. The pressure relief valve includes a spring and a valve ball. The upper cover is coaxial with the pressure relief valve housing and is designed as a single unit, with the spring installed inside the hollow housing. The lower cover has a cantilever that engages with the other end of the housing, forming a cavity in which the valve ball is placed. The filter paper is formed into a cylindrical shape and fitted over the housing; one end of the filter paper is bonded to the upper cover, and the other end is bonded to the lower cover.

[0003] Existing automotive electric bridge filters are assembled manually, especially the filter paper. The filter paper has a steel wire layer, which has a certain rigidity but also has the problem of unstable shape, making assembly difficult, resulting in low assembly efficiency and high labor costs. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the technical problem solved by the present invention is to provide a filter paper loading mechanism for an electric bridge filter processing equipment, so as to realize automatic filter paper loading.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the filter paper loading mechanism of the electric bridge filter processing equipment is characterized in that it includes a filter paper clamping assembly, a pushing assembly, and a moving frame, wherein the filter paper clamping assembly and the pushing assembly are disposed on the moving frame.

[0006] A filter paper clamping assembly includes an upper clamping member and a lower clamping member. When the lower clamping member is closed, the minimum inner diameter of its lower clamping opening is smaller than the inner diameter of the upper clamping opening when the upper clamping member is closed, and the upper and lower clamping openings are on the same center line.

[0007] The pushing component includes a vertically movable pushing head, which is positioned above the upper clamping member and corresponds to the upper clamping opening.

[0008] When the filter paper is removed, the upper clamping member holds the upper end of the filter paper, while the lower clamping member is not closed. At this time, the inner diameter of the filter paper is relatively large, allowing it to be easily fitted onto the pressure relief valve housing. The moving frame moves, and the upper clamping member holding the filter paper moves to directly above the end cover, with the bottom of the filter paper corresponding to the mounting groove on the end cover. At this time, the lower clamping member closes, clamping and tightening the lower end of the filter paper, allowing the bottom of the filter paper to enter the mounting groove on the end cover. At this time, the lower end of the filter paper is smaller than the upper end. The pushing head moves down and pushes the filter paper, causing the filter paper to move down relative to the upper and lower clamping members. After the lower end of the filter paper passes through the lower clamping opening of the lower clamping member and is tightened, it enters the mounting groove, thus achieving automatic assembly of the filter paper.

[0009] Preferably, the lower clamping member includes a first lower clamping head and a second lower clamping head arranged horizontally and symmetrically. Each lower clamping head includes a filter paper clamping portion for clamping filter paper. The clamping surface of the filter paper clamping portion has an inclined section. After the first and second lower clamping heads are closed, the inclined section of the lower clamping opening is an inverted frustum shape. The inverted frustum-shaped clamping opening forms a tightening guide opening, gradually tightening the loose filter paper so that the bottom of the filter paper can smoothly enter the mounting groove.

[0010] Preferably, the inclined clamping surface of the filter paper clamping part extends downward to a vertical section. After the first and second lower clamping heads are closed, the vertical section of the lower clamping opening is cylindrical. The cylindrical clamping opening plays a shaping and stabilizing role, ensuring that the filter paper portion entering the mounting groove is cylindrical before entering. This results in a stable shape of the filter paper portion entering the mounting groove and a better fit with the mounting groove, leading to a better assembly effect.

[0011] Preferably, the first and second lower clamping heads further include an end cap clamping portion for clamping the end cap. The end cap clamping portion is located below the filter paper clamping portion, and the clamping surface of the end cap clamping portion matches the side surface of the end cap. When the lower clamping members are closed, they clamp the end cap together, which allows assembly to be performed during movement, improving assembly efficiency.

[0012] Preferably, the first lower clamping head and the second lower clamping head move horizontally, and when closed, they move horizontally toward each other.

[0013] The movable frame is equipped with guides for the horizontal movement of the first and second lower clamping heads. The horizontal movement of the first and second lower clamping heads is stable and the clamping and tightening accuracy is high.

[0014] Preferably, a counterweight is fitted onto the top of the filter paper, and the counterweight is tightly fitted to the filter paper, with the upper clamping member clamping outside the counterweight. The counterweight is designed to keep the filter paper in a cylindrical shape, preventing excessive looseness from affecting the clamping operation.

[0015] Preferably, when taking the filter paper, the upper clamping member clamps the upper end of the filter paper, and the lower clamping member is not closed; when assembling the filter paper, the lower clamping member closes and clamps the lower end of the filter paper, and the pushing head moves down and pushes the filter paper.

[0016] Preferably, the movable frame can move longitudinally and move up and down.

[0017] The movable frame is also equipped with a product retrieval component, which is arranged longitudinally side by side with the filter paper clamping component. The product retrieval component includes a product retrieval clamp. The movement of the movable frame causes the filter paper clamping component and the product retrieval component to move synchronously. When the filter paper clamping component delivers the assembled filter paper to the shaping station, the product retrieval component picks up the shaped filter paper. When the filter paper clamping component picks up the top cover or assembles the filter paper, the product retrieval component delivers the shaped filter paper to the empty position of the filter paper, thereby improving the efficiency of filter paper assembly.

[0018] Preferably, the sample clamp includes a plurality of vertically arranged sample clamping heads, which are evenly arranged on a circumference and move radially; during clamping, the plurality of sample clamping heads converge towards the center. The plurality of sample clamps clamp the shaped filter paper by radial movement, shortening the travel distance of the sample clamps and providing more operating space for the filter paper clamping assembly.

[0019] Preferably, a counterweight is fitted onto the top of the filter paper, and the counterweight is tightly fitted to the filter paper. The clamping surface of the sample-taking clamping head is stepped, and the sample-taking clamping head clamps and supports the counterweight. This results in a better clamping effect.

[0028] The filter paper loading mechanism of this type of bridge filter processing equipment includes a filter paper clamping assembly, a pushing assembly, and a moving frame 14. The filter paper clamping assembly and the pushing assembly are mounted on the moving frame 14. The filter paper clamping assembly includes an upper clamping member 16 and a lower clamping member 17. When the lower clamping member 17 is closed, the minimum inner diameter of its lower clamping opening 28 is smaller than the inner diameter of the upper clamping opening 27 when the upper clamping member 16 is closed, and the upper clamping opening 27 and the lower clamping opening 28 are on the same center line. The lower clamping member 17 includes a first lower clamping head 21 and a second lower clamping head 22. The first lower clamping head and the second lower clamping head include a filter paper clamping part 26 for clamping filter paper. The clamping surface 20 of the filter paper clamping part 26 has an inclined section 25. After the first lower clamping head 21 and the second lower clamping head 22 are closed, the inclined section 25 of the lower clamping opening is an inverted frustum shape, and the lower clamping opening 28 plays a tightening and guiding role. The pushing assembly includes a vertically movable pushing head 15, which is positioned above the upper clamping member 16 and corresponds to the upper clamping opening 27, for pushing the filter paper 40. When removing the filter paper, the upper clamping member 16 clamps the upper end of the filter paper, and the lower clamping member 17 is not closed; when assembling the filter paper, the lower clamping member 17 closes and clamps the lower end of the filter paper, the pushing head 15 moves down and pushes the filter paper 40, and the lower end of the filter paper passes through the lower clamping opening 28 and is tightened into the mounting groove. Specifically, the cylindrical filter paper 40 is fitted downwards from above the pressure relief valve housing 10 of the upper end cover. When removing the filter paper, only the upper clamping member 16 clamps the upper end of the filter paper, leaving a large inner hole in the filter paper, so that it can be easily fitted onto the pressure relief valve housing 10. After the upper clamping member 16 clamps the filter paper, the moving frame 14 moves so that the filter paper clamped by the upper clamping member 16 is sleeved outside the pressure relief valve housing 10. At this time, the bottom of the filter paper is close to the mounting groove of the upper end cover 41. The lower clamping member 17 closes, tightening the lower end of the loose filter paper. The inverted frustum-shaped clamping opening forms a tightening guide opening. The lower end of the filter paper is smaller than the upper end of the filter paper. The pushing head 15 moves down and pushes the filter paper 40. The filter paper moves down relative to the upper clamping member 16 and the lower clamping member 17. The lower end of the filter paper is tightened and guided smoothly into the mounting groove through the lower clamping opening 28 of the lower clamping member 17, realizing the automatic assembly of the filter paper.

[0029] The inclined section 25 of the filter paper clamping part 26 extends downward from the clamping surface to a vertical section 24. After the first lower clamping head 21 and the second lower clamping head 22 are closed, the vertical section 24 of the lower clamping opening is cylindrical. As the inclined section 25 at the lower end of the filter paper gradually tightens, the cylindrical vertical section 24 plays a shaping and stabilizing role, so that the filter paper part entering the mounting groove is in a tightened straight cylinder shape before entering. In this way, the shape of the filter paper part entering the mounting groove is stable and matches the mounting groove, resulting in a better assembly effect.

[0030] The first and second lower clamping heads also include an end cap clamping part 23 for clamping the end cap. The end cap clamping part 23 is located below the filter paper clamping part 26, and the clamping surface of the end cap clamping part 23 matches the side of the end cap. When the lower clamping member 17 is closed, it not only clamps the lower end of the filter paper but also clamps the upper end cap 41 together. That is, when the moving frame 14 moves, the filter paper and the upper end cap 41 move together. This allows the pressing head 15 to press the filter paper into the mounting groove of the upper end cap 41 during the movement, thereby improving the efficiency of filter paper assembly. After the filter paper 40 and the upper end cap 41 are assembled, they are moved to the shaping station 4 for shaping by the moving frame 14.

[0031] The first lower clamping head 21 and the second lower clamping head 22 can move horizontally. When they move towards each other, they close; when they move away from each other, they open. The moving frame 14 is provided with a guide 19 for the horizontal movement of the first lower clamping head and the second lower clamping head. The horizontal movement of the first lower clamping head and the second lower clamping head is stable and the clamping and tightening accuracy is high.

[0032] The movable frame 14 moves longitudinally and rises and falls vertically. The movable frame 14 is also equipped with a product-picking component 18, which is arranged longitudinally side-by-side with the filter paper clamping component. The product-picking component 18 includes a product-picking clamp 35. The movement of the movable frame 14 causes the filter paper clamping component and the product-picking component 18 to move synchronously. When the filter paper clamping component delivers the assembled filter paper to the shaping station 4, the product-picking component 18 picks up the shaped filter paper semi-finished product. When the filter paper clamping component picks up the upper end cap 41 or assembles the filter paper, the product-picking component 18 delivers the shaped filter paper semi-finished product to an empty filter paper station slot, thereby improving the efficiency of filter paper assembly.

[0033] The pick-up clamp 35 includes several vertically arranged pick-up clamping heads, which are evenly distributed around a circumference and move radially. During clamping, the pick-up clamping heads converge towards the center; when released, they spread outwards around the circumference. The radial movement of the pick-up clamps 35 grips the shaped filter paper semi-finished product, shortening the travel distance of the pick-up clamps 35 and providing more operating space for the filter paper clamping assembly. A counterweight 39 is fitted onto the top of the filter paper 40, and the counterweight 39 is tightly fitted to the filter paper 40. The counterweight 39 is positioned to keep the filter paper in a cylindrical shape, preventing excessive looseness from affecting the clamping operation. The clamping surface of the pick-up clamping head is stepped, and the pick-up clamping head grips and supports the counterweight 39, resulting in a better clamping effect.

[0034] The working principle of the preferred embodiment is further explained below with reference to the accompanying drawings: The upper end cover 41, filter paper 40, and lower end cover 42 are placed sequentially in the first workpiece slot 7, filter paper workpiece slot 8, and second workpiece slot 9 of the workpiece seat 6. The moving frame 14 moves to the position where the filter paper is located. At this time, the picking clamp 35 has already picked up the shaped filter paper semi-finished product (one end of the filter paper is bonded to the upper end cover 41) from the shaping station 4. The upper clamping member 16 clamps the upper end of the filter paper, so that the filter paper retains a larger inner hole. Then the moving frame 14 moves upward and then downward. Move left to directly above the upper end cover 41. At this time, the upper end cover has been glued. Then, the moving frame 14 moves down to put the filter paper 40 on the pressure relief valve housing 10 connected to the upper end cover. The lower end of the filter paper is close to the mounting groove of the upper end cover 41. The lower clamping member 17 closes, the filter paper clamping part 26 clamps the lower end of the filter paper, and the end cover clamping part 23 clamps the upper end cover 41. The lower end of the filter paper is tightened and the outer diameter becomes smaller. At the same time, the picking clamp 35 sends the clamped and shaped filter paper semi-finished product to the filter paper workpiece groove 8 and releases the filter paper semi-finished product. After the filter paper clamping part 26 clamps the upper end cover 41, the moving frame 14 moves upward and to the right to the shaping station 4. During this process, the pushing head 15 moves downward, pushing the filter paper 40 downward relative to the upper clamping part 16 and the lower clamping part 17. The lower end of the filter paper passes through the inclined section 25 and the vertical section 24 of the filter paper clamping part 26. The inclined section 25 gradually tightens the filter paper, and the vertical section 24 keeps the filter paper tight. In this way, the lower end of the filter paper is smoothly tightened and guided into the installation groove, and the lower end of the filter paper is bonded to the upper end cover 41. The bonded filter paper and the upper end cover 41 are sent to the shaping station 4, and at the same time, the picking clamp 35 picks up the semi-finished filter paper that has been shaped.
