Abstract
Description
Technical Field
[0001] This invention relates to the field of solution cap opening technology, and in particular to a cap opening device and method based on solution aspiration. Background Technology
[0002] The capping device is a key piece of equipment in solution processing. Its core function is to open the container cap, which facilitates subsequent operations such as solution aspiration and transfer. It is widely used in chemical production, biomedicine, laboratory research and development, food processing and other fields.
[0003] The current method of opening the lid has the following shortcomings: 1. Opening the outer cover requires the outer cover to be in a horizontal position. However, in reality, there will be a certain angle between the outer cover and the horizontal plane. If the angle of the outer cover is slightly large, the outer cover cannot be cut smoothly. Cutting too deeply at higher positions can easily cause the tool to break. Cutting too shallowly at lower positions will result in the outer cover not being cut off, and the tool will still be connected to the outer cover. 2. The outer cap opening device has poor compatibility and can only cut one type of outer cap. When changing to a different model of outer cap, a different model of opening device is required, which will affect the opening efficiency of the container cap and increase the production cost of the entire opening device. 3. When opening the inner cover, it is necessary to identify the angle of the cross groove on the inner cover; otherwise, the tool cannot be accurately inserted into the cross groove, and thus the inner cover cannot be opened. 4. Poor compatibility of the inner cover removal: When using a suction cup to pick up the inner cover, sometimes it cannot be picked up because there are release points, grooves, protrusions, etc. in the middle of the inner cover. 5. Low efficiency: The existing lid opening device is not compatible with opening both inner and outer lids, requiring an inner lid opening mold to open the inner lid and an outer lid opening mold to open the outer lid. Summary of the Invention
[0004] In response to the shortcomings of the existing production technology, the applicant provides a cap-opening device and method based on solution absorption. By improving the cap-opening method, the device can simultaneously open both the inner and outer caps, thereby increasing the cap-opening efficiency and reducing the overall production cost of the cap-opening device.
[0005] The technical solution adopted in this invention is as follows: A solution-absorption-based cap-opening device includes: a driving mechanism and at least two cutters. The driving mechanism has at least two driving ends, and the two cutters are respectively mounted on the two driving ends of the driving mechanism. The driving mechanism is used to drive the cutters to move along the Z-axis, drive the cutters to rotate around the XOY plane, and drive the cutters to move along the radial direction of the cap. Specifically: when the cutter moves towards the side closer to the cap and moves from the inside to the outside along the radial direction of the cap, the cutter is used for cap-cutting opening; when the cutter abuts against the cap and moves away from the cap, the cutter is used for spiral-ascending cap-opening.
[0006] Therefore, by driving two blades through a drive mechanism to perform cutting and spiral lifting operations, this method is simpler in structure and easier to operate than existing lid opening methods. It can simultaneously open the inner and outer lids (i.e., open the outer and inner lids at once), thereby improving the lid opening efficiency and reducing the production cost of the entire lid opening device. In addition, it can adapt to the tilted state of the lid and is compatible with different models of lids. Furthermore, it eliminates the need to align the blades with the cross groove of the inner lid, further improving the lid opening efficiency.
[0007] As a further improvement to the above technical solution: the driving mechanism includes: a first driving part, a second driving part, and a third driving part. The second driving part is connected to the driving end of the first driving part, and the third driving part is connected to the driving end of the second driving part. The cutting tool is mounted on the driving end of the third driving part. Wherein: the first driving part is used to drive the cutting tool to move along the Z-axis direction, the second driving part is used to drive the cutting tool to rotate around the XOY plane, and the third driving part is used to drive the cutting tool to move along the radial direction of the cover.
[0008] As a further improvement to the above technical solution, the multiple cutting tools are centrally symmetrical about the axis of the cover. Therefore, the purpose of central symmetry of the multiple cutting tools about the axis of the cover is to maintain a balance between the cutting force and clamping force of the tools on the cover, thereby avoiding unbalanced forces on the cover, ensuring a smooth cut and stable spiral ascent, reducing the risk of the cover getting stuck, and also ensuring that the contact depth between each tool and the cover remains consistent to accommodate covers with different postures.
[0009] As a further improvement to the above technical solution: the tool has a cutting edge, which is located on the side away from the axis of the cover; wherein: when the tool moves from the inside to the outside along the radial direction of the cover, the cutting edge is used for cutting-type opening of the cover. Thus, when opening the outer cover, the cutting edge contacts the outer cover, and when the tool moves from the inside to the outside along the radial direction of the cover, the movement of the tool causes the cutting edge to act on the outer cover, thereby achieving a cutting-type opening of the outer cover.
[0010] As a further improvement to the above technical solution: the cutting tool also has a side portion; wherein, when the side portion abuts against the inner cover, at least two cutting tools work together to fix the inner cover. Thus, when opening the inner cover, the side portion abuts against the inner cover, and when the cutting tool rotates along the XOY plane, a rotational force is generated between the two cutting tools and the inner cover. This rotational force pushes the inner cover to rotate, while ensuring that the inner cover does not detach from the cutting tool's restraint. Under the action of the first driving unit applying an upward force to the cutting tool, a spiral upward opening operation of the inner cover is achieved.
[0011] As a further improvement to the above technical solution, a detection element is provided on the third drive unit. Therefore, the stroke of the drive end of the third drive unit can be detected by the detection element to accommodate cross-shaped grooves of different sizes for different models of inner covers.
[0012] As a further improvement to the above technical solution, it also includes: a mounting block, wherein the cutting tool is mounted on the driving end of the third driving unit via the mounting block; wherein the mounting block is provided with a clearance groove.
[0013] A cap-opening method for a cap-opening device based on solution aspiration includes the following steps: S1. In the initial state: all the cutters are close to each other, and the center point of the cutter is located directly above the cover; S2. The drive mechanism drives the two cutters to move in order to open the cover.
[0014] As a further improvement to the above technical solution, step S2 includes the following steps: S2-1. The first driving unit drives the cutter to move along the Z-axis towards the side closer to the cover, and inserts the cutter into the outer cover; S2-2. The cutting tool remains stationary in the Z-axis direction, and the two third driving parts drive the two cutting tools away from each other so that the cutting edge cuts the outer cover, thereby realizing the cutting-type opening operation of the outer cover. S2-3. After the outer cover opening operation is completed, the side part abuts against the inner cover, the third drive unit is closed, and the first and second drive units are simultaneously opened, so that the cutter moves away from the cover body along the Z-axis while rotating around the XOY axis, thereby realizing the spiral upward opening operation of the inner cover. Thus, the outer cover is cut open by cutting, and the inner cover gradually detaches from the container by spiral upward, thereby realizing the opening operation of the double-layer cover (i.e., the outer cover + inner cover combination cover). In addition, during the spiral upward process of the inner cover, the outer cover gradually detaches from the container under the driving force of the spiral upward force of the inner cover.
[0015] As a further improvement to the above technical solution, step S2 includes the following steps: S2-A: While the first driving unit drives the cutter to move along the Z-axis towards the side of the cover, the two third driving units drive the two cutters to move away from each other so that the side part abuts against the cover. S2-B, Close the third drive unit and simultaneously open the first and second drive units, so that the cutter moves away from the cover along the Z-axis while rotating around the XOY axis, thereby achieving a spiral-up opening operation of the cover. Thus, the cover gradually detaches from the container in a spiral-up manner, achieving a single-layer cover opening operation.
[0016] The beneficial effects of this invention are as follows: This invention uses a drive mechanism to drive two blades for cutting and spiraling operations. Compared to existing lid opening methods, this method has a simpler structure, is easier to operate, and can simultaneously open both the inner and outer lids (i.e., open both the outer and inner lids at once), thereby improving the lid opening efficiency and reducing the overall production cost of the lid opening device. In addition, it can adapt to the tilted state of the lid and is compatible with different lid models. Furthermore, it eliminates the need to align the blades with the cross groove of the inner lid, further improving the lid opening efficiency.
[0017] The present invention also includes the following advantages: 1. The purpose of the multiple cutting tools of the present invention being centrally symmetrical about the axis of the cover is to keep the cutting force and clamping force of the cutting tools on the cover balanced, so as to avoid the unbalanced force on the cover, to ensure that the cut of the cover remains flat and the spiral rise is smooth, reducing the risk of the cover getting stuck. At the same time, it can also ensure that the contact depth between each cutting tool and the cover is consistent, so as to adapt to the cover in different postures.
[0018] 2. When the outer cover is opened, the blade contacts the outer cover. When the blade moves from the inside to the outside along the radial direction of the cover, the movement of the blade makes the blade act on the outer cover, so as to realize the cutting-type opening operation of the outer cover.
[0019] 3. When the inner cover is opened, the side part of the present invention abuts against the inner cover. When the cutter rotates along the XOY plane, a rotational force is generated between the two cutters and the inner cover. This rotational force will push the inner cover to rotate. At the same time, this rotational force can ensure that the inner cover will not be freed from the restraint of the cutter. Under the action of the first drive part applying an upward force to the cutter, the spiral upward opening operation of the inner cover is realized.
[0020] 4. The present invention can detect the stroke of the drive end of the third drive unit (i.e. the stroke of the tool) through the detection component, so as to adapt to the cross grooves of different sizes of inner covers of different models. Attached Figure Description

[0023] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.
[0024] Example 1: like Figures 1 to 7 As shown, a cap-opening device based on solution absorption includes: a drive mechanism 1 and at least two cutters 2. The drive mechanism 1 has at least two drive ends, and the two cutters 2 are respectively mounted on the two drive ends of the drive mechanism 1. The drive mechanism 1 is used to drive the cutters 2 to move along the Z-axis, drive the cutters 2 to rotate around the XOY plane, and drive the cutters 2 to move along the radial direction of the cap. Specifically: when the cutter 2 moves towards the side closer to the cap and moves from the inside to the outside along the radial direction of the cap, the cutter 2 is used for cap-cutting type cap-opening operation; when the cutter 2 abuts against the cap and moves away from the cap, the cutter 2 is used for spiral-rising type cap-opening operation. Therefore, by driving the two cutters 2 through the drive mechanism 1 to perform cutting and spiral lifting operations, compared with the existing lid opening methods, this method has a simple structure and is easy to operate. It can simultaneously open the inner and outer lids, that is, open the outer lid and the inner lid at one time, thereby improving the lid opening efficiency and reducing the production cost of the entire lid opening device. In addition, it can adapt to the tilted state of the lid and is compatible with different models of lids. At the same time, there is no need to align the cutter 2 with the cross groove of the inner lid, which further improves the lid opening efficiency.
[0025] It should be noted that: 1. Under the action of the drive mechanism, the cutter can achieve multi-directional movement. Through the combination of cutting and spiral rising operations, it can open the cover in one go and adapt to the tilt state of the cover. Second, the cutting method is from the inside out (i.e., cutting from the center of the cover towards the edge of the cover), leaving a gap below (i.e., a gap at the center of the inner cover, not directly penetrating the inner cover). The cutting position has a certain depth, so even if the cover is tilted, it is still within the cutting range.
[0026] It should be noted that: 1. The cover with the cross groove can be equipped with two or four cutters 2; 2. The cover with a slotted groove is equipped with two cutting tools 2.
[0027] It should be noted that: I. For example Figure 5 As shown, the double-layered lid, or combined lid, consists of an outer lid and an inner lid. The inner lid is threaded to the container, and the outer lid is connected to the container. The outer lid wraps around the inner lid, and the inner lid has a cross groove or a slot on its side near the outer lid in the Z-axis direction. II. Single-layer cap is threaded to the container, wherein: a cross groove or a slotted groove is provided on the surface away from the container in the Z-axis direction (e.g., Figure 6 As shown), a cross groove or a slot is formed on the surface away from the container in the Z-axis direction (e.g., Figure 7 (As shown).
[0028] In this embodiment, the drive mechanism 1 includes a first drive unit 101, a second drive unit 102, and a third drive unit 103. The second drive unit 102 is connected to the drive end of the first drive unit 101, and the third drive unit 103 is connected to the drive end of the second drive unit 102. The cutter 2 is mounted on the drive end of the third drive unit 103, and a detection element 104 is provided on the third drive unit 103. Specifically, the first drive unit 101 drives the cutter 2 to move along the Z-axis, the second drive unit 102 drives the cutter 2 to rotate around the XOY plane, and the third drive unit 103 drives the cutter 2 to move along the radial direction of the cover. Thus, the travel of the cutter 2 at the drive end of the third drive unit 103 can be detected by the detection element 104 to accommodate different sizes of cross grooves in different models of inner covers.
[0029] Specifically, the first drive unit 101 includes a linear guide rail and a slider, the slider being slidably connected to the linear guide rail, and the second drive unit 102 being mounted on the slider.
[0030] For example, the second drive unit 102 uses a motor, the third drive unit uses a cylinder, and the detection unit 104 uses a distance sensor.
[0031] It should be noted that the third drive unit is also equipped with a throttle valve 105, which enables the cutter 2 to have flexible cutting capabilities and can adjust the cutting force and tension of the cutter 2 relative to the outer cover.
[0032] In this embodiment, the purpose of having multiple cutters 2 centrally symmetrical about the axis of the cover is to keep the cutting force and clamping force of the cutters 2 on the cover balanced, so as to avoid unbalanced force on the cover, ensure that the cut of the cover remains flat and the spiral rise is smooth, reduce the risk of the cover getting stuck, and at the same time, ensure that the contact depth between each cutter 2 and the cover remains consistent, so as to adapt to the cover in different postures.
[0033] In this embodiment, the cutter 2 has a cutting edge 201, which is located on the side away from the axis of the cover. When the cutter 2 moves from the inside to the outside along the radial direction of the cover, the cutting edge 201 is used for a cutting-type opening operation. Thus, when opening the outer cover, the cutting edge 201 contacts the outer cover. As the cutter 2 moves from the inside to the outside along the radial direction of the cover, the movement of the cutter 2 causes the cutting edge 201 to act on the outer cover, thereby achieving a cutting-type opening operation.
[0034] In this embodiment, the cutter 2 also has a side portion 202; wherein, when the side portion 202 abuts against the inner cover, at least two cutters 2 are used together to fix the inner cover. Thus, when opening the inner cover, the side portion 202 abuts against the inner cover, and when the cutter 2 rotates along the XOY plane, a rotational force is generated between the two cutters 2 and the inner cover. This rotational force will push the inner cover to rotate. At the same time, this rotational force can ensure that the inner cover will not be released from the restraint of the cutter 2, and under the action of the first drive unit 101 applying an upward force to the cutter 2, a spiral upward opening operation of the inner cover is realized.
[0035] In this embodiment, it also includes: a mounting block 3, through which the tool 2 is mounted on the driving end of the third driving part 103; wherein, the mounting block 3 is provided with a clearance groove 301.
[0036] Example 2: like Figures 8 to 9 As shown, a cap-opening method for a cap-opening device based on solution aspiration includes the following steps: S1. In the initial state: all two cutters 2 are close to each other, and the center point of cutter 2 is located directly above the cover; S2, the drive mechanism 1 drives the two cutters 2 to move in order to open the cover.
[0037] In this embodiment, S2 includes the following steps: S2-1, The first drive unit 101 drives the cutter 2 to move along the Z-axis towards the side closer to the cover, and inserts the cutter 2 into the outer cover; S2-2, the cutter 2 remains stationary in the Z-axis direction, and the two third drive units 103 drive the two cutters 2 to move away from each other so that the blade 201 cuts the outer cover, thereby realizing the cutting-type opening operation of the outer cover. S2-3. After the outer cover opening operation is completed, the side part 202 abuts against the inner cover, the third drive part 103 is closed, and the first drive part 101 and the second drive part 102 are opened simultaneously, so that the cutter 2 moves away from the cover body along the Z-axis while rotating around XOY, so as to realize the spiral upward opening operation of the inner cover. Thus, the outer cover is cut open by cutting, and the inner cover is gradually separated from the container by spiral upward, so as to realize the opening operation of the double-layer cover (i.e., the outer cover + inner cover combination cover). In addition, during the spiral upward process of the inner cover, the outer cover is gradually separated from the container under the driving force of the spiral upward force of the inner cover.
[0038] Example 3: like Figure 10 As shown, the difference from Embodiment 2 is that S2 includes the following steps: S2-A, while the first drive unit 101 drives the cutter 2 to move along the Z-axis towards the side closer to the cover, the two third drive units 103 drive the two cutters 2 to move away from each other so that the side part 202 abuts against the cover. S2-B, Close the third drive unit 103 and simultaneously open the first drive unit 101 and the second drive unit 102, so that the cutter 2 moves away from the cover along the Z-axis while rotating around the XOY axis, thereby realizing a spiral upward opening operation of the cover. Thus, the cover gradually detaches from the container in a spiral upward manner, thereby realizing the opening operation of a single-layer cover.
[0039] In summary, this invention uses a drive mechanism 1 to drive two blades 2 for cutting and spiral-ascending operations. Compared to existing lid-opening methods, this method has a simpler structure, is easier to operate, and can simultaneously open both the inner and outer lids (i.e., open both the outer and inner lids at once), thereby improving the lid-opening efficiency and reducing the overall production cost of the lid-opening device. In addition, it can adapt to the tilted state of the lid and is compatible with different lid models. Furthermore, it eliminates the need to align the blades 2 with the cross groove of the inner lid, further improving the lid-opening efficiency.
