Technical Field

[0001] This utility model belongs to the field of testing equipment, and in particular relates to an automatic alignment device for testing bottle detection equipment. Background Technology

[0002] In existing testing equipment, sample vials generally need to be positioned on the platform using an active positioning device. This type of equipment requires a relatively complex positioning and detection mechanism, and the main unit also needs to be equipped with camera positioning and adjustment software, which is costly and has a high failure rate, affecting the testing of samples. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic alignment device that, through mechanical adjustment, aims to solve the technical problems of complex structure, high cost, and high failure rate in the prior art.

[0004] This invention is implemented as follows: the automatic filling device for test sample bottles includes a support platform mounted on a frame for carrying test sample bottles, a filling unit mounted on the frame, and a bottle mouth alignment device disposed between the support platform and the filling unit. The bottle mouth alignment device includes a bracket mounted on the frame, a lifting mechanism that moves up and down along the bracket, and a pressing unit disposed on the lifting mechanism. The pressing unit is provided with an alignment mechanism for aligning the bottle mouth, and the alignment mechanism is provided with a filling channel. The filling tube in the filling unit is aligned with the filling channel.

[0005] A further technical solution of this utility model is: the alignment mechanism is a block-shaped body fixed on the pressing unit, the liquid filling channel is located in the center of the block-shaped body, and both the upper and lower ends of the liquid filling channel are funnel-shaped openings that face outwards.

[0006] A further technical solution of this utility model is: the lifting mechanism includes a guide rail disposed on the bracket, a lifting drive motor disposed on the bracket, and a transmission mechanism connecting the lifting drive motor and the slider disposed on the guide rail, wherein the bracket is movably connected to the slider through the guide rail.

[0007] A further technical solution of this utility model is: the transmission mechanism (423) includes a belt, a driven wheel, a belt fixing block and a lifting block. The lifting drive motor is connected to the driven wheel through the belt to form a belt drive. The belt fixing block is set on the belt. The lifting block is movably placed on the belt. The lifting block is placed above the belt fixing block. One end of the lifting block is fixedly connected to the slider.

[0008] The beneficial effects of this utility model are: by using a mechanical alignment mechanism, this utility model eliminates the need for a relatively complicated electronic correction and adjustment mechanism, and can directly achieve the problem of accurate alignment, simplifying the equipment structure and cost, and reducing the failure rate.

[0009] Figure 1 This is an overall schematic diagram of the testing equipment provided in this embodiment of the utility model; Figure 2 This is a cross-sectional schematic diagram of the alignment mechanism provided in an embodiment of this utility model. Detailed Implementation

[0010] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0011] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0012] like Figure 1 As shown, the automatic sample bottle filling device provided by this utility model includes a support platform 20 mounted on a frame 10 for carrying the sample bottles, a filling unit 30 mounted on the frame 10, and a bottle mouth alignment device 40 disposed between the support platform 20 and the filling unit 30. The bottle mouth alignment device 40 includes a bracket 41 mounted on the frame 10, a lifting mechanism 42 that moves up and down along the bracket 41, a pressing unit 43 disposed on the lifting mechanism 42, and an alignment mechanism 44 disposed on the pressing unit 43 for aligning the bottle mouth. The alignment mechanism 44 is provided with a filling channel 441, and the filling tube 31 in the filling unit 30 is aligned with the filling channel 441. In this solution, a mechanical automatic alignment mechanism is used to automatically align the bottle mouth of the sample bottle with the filling channel 441, achieving accurate automatic filling. The use of a mechanical automatic adjustment mechanism avoids the complex structure of electronic positioning adjustment mechanisms, reducing costs and the failure rate.

[0013] like Figure 2 As shown, the alignment mechanism 44 is a block-shaped body fixed to the pressing unit 43. The filling channel 441 is located in the center of this block-shaped body, and the lower end of the filling channel 441 is shaped like a trumpet 442. The lifting mechanism 42 includes a guide rail 421 mounted on the bracket 41, a lifting drive motor 422 mounted on the bracket 41, and a transmission mechanism 423 connecting the lifting drive motor 422 and the slider 424 mounted on the guide rail 421. The bracket 41 is movably connected to the slider 424 through the guide rail 421. In this solution, the automatic alignment function of the trumpet 44 is used for adjustment. If the bottle mouth is not aligned with the filling channel, the trumpet 44 on the pressing unit 43 can automatically align the bottle mouth to the middle position, so that the bottle mouth can be aligned with the filling port, ensuring the accuracy of filling.

[0014] This positioning device includes a positioning head, a slider, a slide rail, a lifting block, and a lifting power mechanism. The positioning head and the lifting block are both fixedly mounted on the slider. The lifting power mechanism includes a motor, a belt, and a belt fixing block. The belt fixing block moves up and down with the belt, while the lifting block moves up and down with the slider as a whole and is detached from the belt. When the belt fixing block rises, it contacts the lifting block, lifting the entire slider. When the belt fixing block descends, the slider, under its own weight, slides down until the positioning head presses against the bottle neck.

[0015] The positioning head is hourglass-shaped, with cones at both the top and bottom. When pressed against the bottle opening, it adjusts the bottle opening to the center position. Then, the liquid dispensing module drives the dispensing needle to descend. Guided by the upper cone, the needle enters below the bottle opening, ensuring accurate positioning.

[0016] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
