Description

Technical Field

[0001] This utility model relates to the field of positioning and clamping technology, and in particular to a bottle cap positioning and clamping device. Background Technology

[0002] When adding or removing reagents from reagent bottles, a capping operation is required. In the existing technology, manual tightening is usually used for a small number of reagent bottles. When there are a large number of reagent bottles to be operated, a positioning clamping device is used to clamp and fix the reagent bottles, and then an automated capping device is used to perform the capping operation to improve efficiency.

[0003] For example, Chinese Patent Publication No. CN114772341B discloses an automatic bottle capping machine, including a bottle feeding mechanism, a cap feeding mechanism, a first capping mechanism, a second capping mechanism, a first bottle feeding wheel, and a second bottle feeding wheel; the bottle feeding mechanism includes a bottle conveyor belt, and the first bottle feeding wheel and the second bottle feeding wheel are positioned opposite each other on both sides of the conveyor belt in the conveying direction; the cap feeding mechanism includes a cap feeding turntable; the first capping mechanism and the second capping mechanism are arranged side by side by a bracket and are respectively located above the bottle conveyor belt and the cap feeding turntable to complete the cap gripping or capping operation; the bracket is provided with a rotary drive servo device for driving the first capping mechanism and the second capping mechanism to rotate and exchange their positions.

[0004] The aforementioned device secures the reagent bottle using a first inlet wheel and a second inlet wheel. However, during use, because the shapes of the first and second inlet wheels cannot be changed, it can only be used with reagent bottles of the same size. For larger reagent bottles, the existing device is prone to squeezing the outside of the bottle, causing damage and unnecessary losses. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing devices easily squeeze the outside of reagent bottles when used with large-sized reagent bottles, causing damage and unnecessary losses. The proposed device is a bottle cap positioning and clamping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bottle cap positioning and clamping device, including a base, a column fixedly connected to the upper end of the base, and three sets of columns spaced apart, a support plate fixedly connected to the upper end of the three sets of columns, and a through hole opened at the center of the support plate, a chuck cylinder fixedly installed at the upper end of the base, and the chuck cylinder is located inside the three sets of support plates, the chuck cylinder is concentrically arranged with the through hole, a placement groove is opened at the center of the upper end of the chuck cylinder, a chuck claw is embedded in the outer surface of the chuck cylinder, a clamping component is provided at one end of the chuck claw, and three sets of chuck claws and clamping components are spaced apart.

[0007] Preferably, the clamping assembly includes a deformation component disposed at the end of the jaw, and adjustment components are disposed on both sides of the jaw. The ends of the two sets of adjustment components are embedded in one side of the deformation component, and the deformation component and the adjustment component are disposed above the chuck cylinder.

[0008] Preferably, the deformable component includes a connecting plate fixedly connected to one end of the claw, and an elastic plate is fixedly connected to one end of the connecting plate.

[0009] Preferably, a rubber strip is fixedly connected to the side of the elastic plate near the center of the chuck cylinder, and multiple sets of rubber strips are arranged at intervals.

[0010] Preferably, the rubber strip has a fitting hole on the side near the connecting plate, and multiple sets of fitting holes are provided at intervals.

[0011] Preferably, the adjusting component includes a fixed frame fixedly connected to one side of the claw, and I-shaped sliders are slidably connected through both sides of the fixed frame.

[0012] Preferably, an electric telescopic rod is fixedly connected to one side of the I-shaped slider, and one end of the electric telescopic rod is movably engaged with a set of the engagement holes.

[0013] Preferably, a T-shaped rod is movably provided through the upper end of the I-shaped slider, and the T-shaped rod is provided through the upper end of the fixing frame. Multiple sets of clearance grooves for placing the T-shaped rod are provided at intervals on the upper end and inner side of the fixing frame.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This application achieves the positioning and clamping function of reagent bottles through the setting of chuck cylinder, chuck jaws and clamping components, which can be adapted to the use of automated capping. The setting of deformable elastic plate makes the device adaptable to reagent bottles of different sizes, improving the applicability of the device. When the device clamps and fixes the reagent bottle, the elastic plate and rubber strip have the same curvature as the reagent bottle, so the reagent bottle is subjected to more uniform force, reducing the possibility of the reagent bottle being squeezed and damaged.

[0022] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0023] Example

[0024] Reference Figures 1 to 5 The bottle cap positioning and clamping device includes a base 1, with columns 2 fixedly connected to the upper end of the base 1. Three sets of columns 2 are spaced apart. Support plates 3 are fixedly connected to the upper ends of the three sets of columns 2. A through hole 7 is opened at the center of the support plate 3. A chuck cylinder 4 is fixedly installed on the upper end of the base 1. The chuck cylinder 4 is located inside the three sets of support plates 3. The chuck cylinder 4 is concentric with the through hole 7. A placement groove is opened at the center of the upper end of the chuck cylinder 4. A chuck claw 5 is embedded in the outer surface of the chuck cylinder 4. A clamping component 6 is provided at one end of the chuck claw 5. Three sets of chuck claw 5 and clamping component 6 are spaced apart. It should be noted that the radial movement of the three sets of chuck claw 5 by the chuck cylinder 4 is a known prior art. Those skilled in the art are capable of conceiving the specific structure.

[0025] The clamping assembly 6 includes a deformation component 61 disposed at the end of the jaw 5, and adjustment components 62 disposed on both sides of the jaw 5. The ends of the two sets of adjustment components 62 are embedded in one side of the deformation component 61. The deformation component 61 and the adjustment component 62 are both disposed above the chuck cylinder 4.

[0026] The deformable component 61 includes a connecting plate 611 fixedly connected to one end of the claw 5. An elastic plate 612 is fixedly connected to one end of the connecting plate 611. The elastic plate 612 can be bent into an arc shape when both ends are squeezed.

[0027] A rubber strip 613 is fixedly connected to one side of the elastic plate 612 near the center of the chuck cylinder 4, and multiple sets of rubber strips 613 are arranged at intervals. By arranging multiple sets of rubber strips 613 at intervals, the rubber strips 613 can adapt to the deformation of the elastic plate 612, and can prevent adjacent rubber strips 613 from squeezing each other when the elastic plate 612 deforms, thus preventing the rubber strips 613 from falling off or being damaged.

[0028] The rubber strip 613 has a fitting hole 614 on the side near the connecting plate 611, and multiple sets of fitting holes 614 are provided at intervals.

[0029] The adjusting component 62 includes a fixed frame 621 fixedly connected to one side of the claw 5, and I-shaped sliders 622 are slidably connected through both sides of the fixed frame 621.

[0030] An electric telescopic rod 624 is fixedly connected to one side of the I-shaped slider 622, and one end of the electric telescopic rod 624 is movably engaged with a set of fitting holes 614. The electric telescopic rod 624 can bend one side of the elastic plate 612 by squeezing. Since the fitting hole 614 has a tendency to spring back after being squeezed and bent, the electric telescopic rod 624 will not separate from the fitting hole 614.

[0031] The upper end of the I-shaped slider 622 is movably connected with a T-shaped rod 623, and the T-shaped rod 623 is connected to the upper end of the fixing frame 621. The upper end and inner side of the fixing frame 621 are provided with multiple sets of clearance grooves for placing the T-shaped rod 623. The I-shaped slider 622 can be fixed on the fixing frame 621 by the T-shaped rod 623, and the fixed position can be adjusted.

[0032] In this invention, before capping, the reagent bottle is placed in the groove at the upper end of the chuck cylinder 4, and external force is applied to press the elastic plate 612, so that multiple sets of rubber strips 613 are in contact with the reagent bottle. Then, the position of the I-shaped slider 622 is adjusted so that the electric telescopic rod 624 is engaged with the appropriate fitting hole 614. Subsequently, the shape of the elastic plate 612 is fixed by the pressing of the two sets of electric telescopic rods 624. At this time, the elastic plate 612 and the rubber strips 613 match the curvature of the reagent bottle to be capped. Then, according to the adjusted position and extension parameters of the I-shaped slider 622 and the electric telescopic rod 624, the curvature of the three sets of elastic plates 612 is adjusted. Then, the reagent bottle is placed in the groove at the upper end of the chuck cylinder 4 through an external device. The chuck cylinder 4 causes the three sets of jaws 5 to move radially, so that the three sets of elastic plates 612 are engaged with the reagent bottle. All 12 are close to the reagent bottle. The reagent bottle can be clamped and fixed in the center position of the chuck cylinder 4 by three sets of elastic plates 612 and multiple sets of rubber strips 613. At this time, the upper end of the reagent bottle is exposed through the through hole 7. The external capping device can realize the automated capping operation. The contact between the rubber strips 613 and the reagent bottle is controlled by the chuck cylinder 4, which can adapt to the needs of clamping, fixing and moving the reagent bottle, and is easy to use. This utility model realizes the positioning and clamping function of the reagent bottle, which can adapt to the use of automated capping. By setting the deformable elastic plate 612, the device can adapt to the use of reagent bottles of different sizes, improving the applicability of the device. When the device clamps and fixes the reagent bottle, since the curvature of the elastic plate 612 and the rubber strip 613 is the same as that of the reagent bottle, the force on the reagent bottle is more uniform, reducing the possibility of the reagent bottle being squeezed and damaged.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
