Description

Technical Field

[0001] The present invention belongs to the technical field of medical inspection and microbial culture detection, and specifically relates to an automatic detection and capping device for culture bottles, which is convenient for further analysis and judgment of samples on other instruments. Background Art

[0002] Before medical examination and microbial culture testing, it is necessary to determine whether the quality and quantity of the collected samples meet the requirements, and then press the bottle cap onto the culture bottle. In order to avoid contaminating the sample, there is aluminum platinum paper at the front end of the bottle cap to keep the bottle cap clean and sterile. After removing the aluminum platinum paper, the bottle cap must be pressed onto the culture bottle as soon as possible. The existing method is that the inspector determines whether the sample meets the requirements by observing the liquid level and color in the culture bottle, and then presses the bottle cap onto the culture bottle by manpower, and then sends it to other instruments for culture. The shortcomings of this method are: 1. The judgment of the sample is determined by the inspection personnel's observation, and there is a large human error; 2. The process of pressing the bottle cap onto the culture bottle by manpower is labor-intensive, and there is a phenomenon of inadequate pressing, which makes the culture bottle unable to be placed in the instrument for the next step of culture; 3. When the bottle caps are arranged by using a vibration plate, there is obvious noise and vibration during the operation of the equipment, which is not suitable for the working environment of the laboratory.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0024] like Figure 1-7 As shown, the present invention pre-treats the culture bottles containing the samples to be tested. The present invention includes a frame 1, a rotating mechanism 2, a detection mechanism 3, a bottle cap supply mechanism 4, and a bottle cap pressing mechanism 5. The frame 1 is used to support other mechanisms and parts. The rotating mechanism 2 is installed on the frame 1, and is used to change the position of the culture bottle to complete the detection and capping actions. The detection mechanism 3 is installed on the frame 1, and is composed of a weighing sensor and a liquid level sensor, which detects whether the number of samples contained in the culture bottle meets the requirements from the two aspects of mass and volume. The bottle cap supply mechanism 4 is installed on the frame 1, and is used to accommodate the bottle caps and, through its own action, make the arrangement direction of the bottle caps completely consistent and in the specified position. The bottle cap pressing mechanism 5 is installed on the frame 1, and is used to press the bottle caps onto the culture bottles.

[0025] The frame 1 includes a machine foot 11, a foot pad 12, a support column 13, a mutually parallel machine base 14 and an intermediate plate 15, which are used to support other mechanisms and parts. The foot pad 12 is used to reduce and eliminate noise and vibration during the operation of the device.

[0026] The rotating mechanism 2 is arranged on the base 14, and includes a turntable 21, a pull-out plate 22, a plastic pinion 23, a large gear 24, and a stepper motor 25. The plastic pinion 23 is mounted on the stepper motor 25 and meshes with the large gear 24 below the turntable 21 to realize a reduction transmission. The purpose of using plastic material for the pinion 23 is to reduce the noise during the operation of the present invention. A pull-out plate 22 coaxial with the turntable 21 is arranged above the turntable 21. When the sensor detects that there is a culture bottle in the culture bottle placement area, a rotation signal is issued, and the stepper motor 25 drives the gear to drive the turntable 21 and the pull-out plate 22 to rotate, thereby driving the culture bottle to rotate and change its position. The rotation angle and the stop position are jointly controlled and positioned by the positioning pin and the sensor to ensure that the position of the culture bottle placed on the turntable is accurate.

[0027] The detection mechanism 3 is arranged on the base 14, and is composed of an electromagnet 31, a fork 32, a weighing sensor 33 and a liquid level sensor. When the culture bottle rotates to the detection area and stops, the electromagnet 31 drives the weighing sensor 33 to rise, and the weighing sensor 33 starts to weigh the culture bottle. At the same time, the liquid level sensor scans the liquid level and color of the culture bottle. The system analyzes and compares the weight, liquid level and liquid color of the culture bottle. If it does not meet the requirements, the fork pushes the culture bottle out from the left side of the device; if it meets the requirements, the rotating mechanism drives the culture bottle to move to the capping area.

[0028] The bottle cap supply mechanism 4 is arranged on the frame 1, and includes a hopper 41, an ejector block 42, a slide 43, a buckle 44, a limit block 45, and a cutter 46. The bottle caps are placed in the hopper 41 in a random direction. Driven by the driving device, the ejector block 42 reciprocates linearly in the hopper 41 along the up and down directions. The shape of the groove on the upper part of the ejector block 42 is adapted to the shape of the bottle caps and is inclined at an angle relative to the horizontal plane. When the ejector block 42 descends to the end point, under the combined effect of the special shape of the hopper 41 and the ejector block, the randomly placed bottle caps roll into the groove above the ejector block 42. The ejector block 42 stops for a while when it ascends to the end point with the bottle caps in its groove. Under the action of gravity, the bottle caps slide along the groove of the ejector block into the slide 43. The slide 43 is designed according to the size of the bottle caps. After the bottle caps fall into the slide, the larger end of the bottle caps is caught by the slide, and the smaller end naturally droops under the action of gravity, so that the small ends of all the bottle caps are arranged downward in the slide.

[0029] The slide 43 is arranged on the middle plate 15, and its working surface is inclined at an angle relative to the horizontal plane. The bottle caps dropped from the hopper 41 slide in a lower direction along this working surface under the action of gravity. A buckle 44 is arranged above the slide to limit the upward movement of the bottle caps. The cutter 46 is arranged on the middle plate 15 and the slide 43, and is driven by the above-mentioned driving device to reciprocate linearly in the up and down directions simultaneously with the ejection block 42. When the cutter 46 moves upward and contacts the bottle cap, it pushes the bottle cap upward, and the buckle 44 limits the upward movement of the bottle cap, and the aluminum platinum paper at the small end of the bottle cap is cut by the cutter. The cutter 46 automatically returns to its original position under the action of the spring and its own gravity.

[0030] After the aluminum foil under the bottle cap is cut, it continues to slide down along the slideway to the end of the slideway in a vertical direction. The stopper 45 arranged in the slideway blocks the large end of the bottle cap, restricting it from continuing to descend and accurately positioning it in the slideway.

[0031] The bottle cap pressing mechanism 5 is installed on the frame 1, and includes an ejector rod 51, a connecting rod 52 and a driving device. When the culture bottle that meets the requirements rotates to the capping area, the driving mechanism drives the ejector rod 51 downward through the connecting rod. The ejector rod 51 presses down the bottle cap accurately positioned in the slide 43. Under the guidance of the slide, the bottle cap is just aligned with the culture bottle in the capping area below it, and the bottle cap is pressed onto the culture bottle. Then, the connecting rod is driven upward by the driving device.

[0032] After the connecting rod 52 moves upward to the end point, the bottle cap in the slideway 43 slides to the end of the slideway.

[0033] The culture bottle with the bottle cap pressed on it moves to the push-out area under the action of the rotating mechanism and is pushed out from the right side of the device by the fork, completing a working cycle and realizing automatic detection and capping of the culture bottle.

[0034] In order to increase the versatility of the present invention, the size of the slideway can be slightly changed according to the size of the bottle cap to adapt to bottle caps of different specifications; the stroke of the driving device can be adjusted to adapt to culture bottles of different heights.

[0035] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
