Description

Technical Field

[0001] This invention relates to the field of filter manufacturing equipment technology, specifically to a filter cotton placement and fixing device and its usage method. Background Technology

[0002] In the field of filter manufacturing, traditional manufacturing processes involve precisely placing filter cotton inside a mold, and then using injection molding to integrally form the outer frame and filter cotton, thereby creating a filter product with specific filtration functions. This manufacturing process requires that the position of the filter cotton in the mold be accurate to ensure that the structural integrity and filtration performance of the filter meet the expected standards after injection molding.

[0003] However, in actual production, the lightweight, thin, and soft characteristics of filter cotton present numerous challenges to the manufacturing process. Currently, most production lines still rely on manual operation to place the filter cotton. This manual operation is not only inefficient but also makes it difficult to guarantee accurate placement each time. Due to errors in manual operation, the filter cotton may be placed crookedly or misaligned, which will directly affect the quality stability of the filter after injection molding.

[0004] Furthermore, these physical properties of filter cotton make it particularly difficult to fix it in the mold. During injection molding, if the filter cotton cannot be stably fixed to the mold, it may shift or deform, resulting in structural defects or reduced filtration performance in the molded filter. This instability not only increases the scrap rate during production but also raises the requirements for subsequent quality control and inspection. Summary of the Invention

[0033] Example 1

[0034] This embodiment provides a filter cotton placement and fixing device, which is used for placing and fixing the filter cotton before the filter is injection molded.

[0035] See Figure 1 The filter cotton placement and fixing device includes a cotton placement mechanism 100 and a fixing member 200. The cotton placement mechanism 100 is used for transporting and placing the filter cotton, and the fixing member 200 is used for fixing the filter cotton on the injection mold. The cotton placement mechanism 100 transports the filter cotton and places it on the injection mold, and the fixing member 200 fixes the filter cotton on the fixed mold 300 of the injection mold.

[0036] See Figures 1 to 4 The cotton feeding mechanism 100 includes a cotton feeding component 110, a cotton pressing component 120, and a cotton feeding drive component. The cotton feeding component 110 is used to carry the filter cotton, the cotton pressing component 120 is used to press the filter cotton, and the cotton feeding drive component is used to drive the cotton feeding component 110 and the cotton pressing component 120.

[0037] See Figures 1 to 3 The cotton placement component 110 has cotton placement positions 111 for holding filter cotton. The number of cotton placement positions 111 is the same as the number of cavities 310 in the fixed mold 300, and the arrangement of the cotton placement positions 111 matches the arrangement of the cavities 310, ensuring a one-to-one correspondence between the cotton placement positions 111 and the cavities 310, which is beneficial for the accurate placement of the filter cotton. The shape of the cotton placement positions 111 matches the shape of the filter cotton, and the size of the cotton placement positions 111 is slightly larger than the filter cotton. When the filter cotton is placed in the cotton placement positions 111, it is interference-fitted with the cotton placement positions 111, thereby fixing the filter cotton relatively on the cotton placement positions 111. In this embodiment, an annular limiting step 1111 is provided on the inner edge of the cotton placement position 111. It is used to limit the depth of the filter cotton placed in the cotton placement position 111, so that the operator can quickly place the filter cotton and avoid the filter cotton from being placed too deep and causing the filter cotton to fall off the cotton placement position 111. In addition, since the filter cotton is flexible, it will deform when the filter cotton is pressed, and will not be blocked by the limiting step 1111.

[0038] Furthermore, the cotton-releasing component 110 has symmetrical clamping portions 112 on its first side. Each clamping portion 112 is a protruding cylindrical structure used for selective clamping by the cotton-releasing drive component. The cotton-releasing component 110 also has a positioning component 113 on its first side, which cooperates with the sensing element on the cotton-releasing drive component to adjust the clamped posture of the cotton-releasing component 110, ensuring accurate alignment between the cotton-releasing component 110 and the fixed mold 300. In this embodiment, the positioning component 113 is made of iron, and the sensing element is an electromagnetic chuck. Simultaneously, the positioning component 113 is arranged at multiple positions on the cotton-releasing component 110, with corresponding sensing elements to ensure accurate and reliable positioning.

[0039] Furthermore, the second side of the cotton-releasing component 110 is provided with multiple mating portions 114, and the fixed mold 300 is provided with multiple mating positions 320. Each mating portion 114 corresponds to one of the mating positions 320, and the corresponding mating portions 114 and mating positions 320 are movably inserted into each other. This insertion allows for accurate docking between the cotton-releasing component 110 and the fixed mold 300. In this embodiment, the mating portion 114 is a protruding cylindrical structure, and the mating position 320 is a countersunk hole structure. It should be noted that the first side of the cotton-releasing component 110 faces the cotton-pressing component 120, and the second side of the cotton-releasing component 110 faces the cavity 310 of the fixed mold 300.

[0040] See Figure 1 and 4 The pressing component 120 includes a base 121 and pressing parts 122. The pressing parts 122 are connected to the base 121 via connecting parts 123 and are used to press down on the filter cotton. The number of pressing parts 122 is the same as the number of cotton placement positions 111, and the arrangement of the pressing parts 122 matches the arrangement of the cotton placement positions 111, ensuring a one-to-one correspondence between the pressing parts 122 and the cotton placement positions 111, which facilitates accurate pressing of the filter cotton by the pressing parts 122. In this embodiment, the pressing parts 122 are elongated plate structures, and extend diagonally along the cotton placement positions 111, so that the pressing parts 122 can comprehensively press down on the filter cotton. Furthermore, the end face of the pressing part 122 away from the base 121 is flat, which is beneficial for pressing down on the filter cotton.

[0041] The cotton feeding drive has a clamping end and a driving end. The clamping end can selectively clamp the clamping part 112 of the cotton feeding component 110. The base 121 of the cotton pressing component 120 is connected to the driving end. When the clamping end clamps the cotton feeding component 110, the cotton feeding component 110 and the cotton pressing component 120 are parallel to each other, and the cotton pressing part 122 corresponds one-to-one with the cotton feeding position 111.

[0042] Review Figure 1The fixing members 200 are used to fix the filter cotton, and their number is the same as the number of cavities 310. The fixing members 200 are arranged one by one in the cavity 310. In this embodiment, the fixing members 200 adopt the hook and loop fastener surface, which can form a large-area adhesion with the filter cotton, so as to achieve a stable fixing effect, keep the filter cotton in a stationary state, and ensure that no positional displacement or folding occurs when the fixed mold 300 and the moving mold are closed for injection molding.

[0043] In practical application: First, place the cotton feeding component 110 flat on the worktable and place filter cotton on its cotton feeding position 111. Then, move the cotton feeding component 110 to the first fixed position. Next, the cotton feeding drive component moves to this position, clamps the cotton feeding component 110 through the clamping end, and drives it to move to a position parallel to the fixed mold 300. After that, the cotton feeding drive component continues to move the cotton feeding component 110 so that it abuts against the fixed mold 300. At this time, the drive end is activated, driving the cotton pressing component 120 to move towards the cotton feeding component 110. The cotton pressing part 122 presses the filter cotton on the cotton feeding position 111 onto the fixed mold 300, so that the filter cotton adheres to the fixing component 200, completing the placement of the filter cotton. Finally, the cotton feeding drive component moves the cotton feeding component 110 again, puts it back on the worktable, and releases it through the clamping end.

[0044] Example 2

[0045] This embodiment provides a method for using a filter cotton placement and fixing device, which is applicable to the filter cotton placement and fixing device of Embodiment 1. Combined with... Figures 1 to 4 The method of using this filter cotton placement and fixing device includes the following steps:

[0046] S1. Place the cotton feeding component 110 flat on the workbench, place the filter cotton on the cotton feeding position 111, and then place the cotton feeding component 110 on the first fixed point position;

[0047] S2. After the cotton feeding drive moves to the first fixed position, the cotton feeding part 110 is clamped by the clamping end, and then the cotton feeding drive drives the cotton feeding part 110 to move to a position parallel to the fixed mold 300.

[0048] S3. The cotton feeding drive moves the cotton feeding component 110 so that the cotton feeding component 110 abuts against the fixed mold 300. Then, the driving end drives the cotton pressing component 120 to move towards the cotton feeding component 110. The cotton pressing part 122 presses the filter cotton on the cotton feeding position 111 onto the fixed mold 300 so that the filter cotton adheres to the fixed part 200, and the filter cotton is placed.

[0049] S4. The cotton feeding drive moves the cotton feeding component 110, and after placing the cotton feeding component 110 on the worktable, the clamping end releases the cotton feeding component 110.

[0050] In step S1, when the cotton feeding component 110 is placed flat on the worktable, its first side faces upward. The placement of the filter cotton on the cotton feeding position 111 is done manually or by automated equipment.

[0051] In step S2, after the cotton-releasing component 110 is clamped at the clamping end, the posture of the cotton-releasing component 110 is adjusted by the cooperation of the positioning component 113 and the sensing component.

[0052] In step S3, when the cotton-feeding part 110 abuts against the fixed mold 300, the two are connected by the insertion of the docking part 114 and the docking position 320.

[0053] This filter cotton placement and fixing device utilizes a cotton-feeding mechanism to precisely support the filter cotton in the feeding position, and then presses the filter cotton against the mold's fixed mold platen using a pressing part. A cotton-feeding drive unit clamps the feeding part and precisely moves it above the fixed mold platen, ensuring the filter cotton is accurately placed in the predetermined position. Furthermore, the device incorporates fixing components on the fixed mold platen to effectively secure the filter cotton, preventing displacement or deformation during injection molding. Through this series of ingenious designs, the device not only significantly improves production efficiency but also ensures the accuracy and stability of filter cotton placement, thereby enhancing product quality and optimizing production costs.
