Abstract
The utility model discloses a test tube holder for an acid-base sampling robot. When the robot is taking a sample to acid-base liquid, the sample is taken by the holder centre gripping test tube. Through the structural design of the clamping device, on one hand, a certain clamping force can be provided, and the safety and reliability of clamping are ensured; on the other hand, the test tube can be prevented from being broken due to excessive clamping force.
Description
Technical Field
The utility model relates to the field of chemical industry, and mainly relates to a test tube holder for an acid-base sampling robot.
Background
The safety and quality control problems of the processes of production, storage, transportation, sale, use and the like of acid-base solutions are increasingly prominent. The retention of acid-base solution product batches is important content of enterprise information construction and quality control, and is also one of links for forming a production-marketing integrated closed-loop cooperative working mode. The acid-base solution product batch is reserved, acid-base solution product quality process monitoring information is provided for production enterprises, and quality assurance and quality basis of the acid-base solution product are provided for customers. The acid-base solution product batch is reserved, so that a customer can timely master the acid-base solution product batch quality information and various performance indexes. Once the product has problems in the using process, the sales department and the production unit can quickly track all relevant information about the quality of the batch of products so as to ensure the maximum benefit of customers, win the credit of enterprises and obtain greater cooperation and benefit.
The traditional way of retention is to manually sample, store in a test tube or other container, and apply a label. With the further combination of automation and chemical production processes, the retention and sampling mode also changes, and a robot can be used for sampling, wherein the robot is usually a moving trolley and is integrated with a multi-degree-of-freedom mechanical arm. But this robot centre gripping test tube sends the test tube to and connects liquid department, treats that liquid collection accomplishes, sends the test tube to the save room again, and whole process need not artifical the participation. The safety of getting to the test tube clamp is very important, gets to press from both sides and to press from both sides too tightly and can be with the test tube breakage, gets to press from both sides too loosely and probably presss from both sides not tightly and leads to the test tube to drop.
Disclosure of Invention
Technical problem to be solved
In order to solve the problems in the prior art, the utility model provides a test tube clamping device for an acid-base sampling robot, which can safely and reliably clamp a test tube.
(II) technical scheme
The technical scheme includes that the test tube holder for the acid-base sampling robot comprises an elastic finger, a movable finger, an inclined connecting rod, a horizontal connecting rod, a motor telescopic rod and a motor, and is characterized in that the elastic finger is mounted on the movable finger, the movable finger is connected with the motor telescopic rod through the inclined connecting rod and the horizontal connecting rod, and the motor telescopic rod is driven by the motor to move linearly.
Further, the elastic finger consists of a finger surface, a spring, a nut and a round shaft.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
As shown in fig. 1 to 4, a test tube holder for an acid-base sampling robot comprises an elastic finger 2, a movable finger 3, an inclined connecting rod 4, a motor 5, a motor telescopic rod 6 and a horizontal connecting rod 7. Elastic finger 2 installs on activity finger 3, activity finger 3 links to each other with motor telescopic link 6 through oblique connecting rod 4, horizontal connecting rod 7, linear motion is done by the drive of motor 5 to motor telescopic link 6, realizes the switching of elastic finger 2, and then realizes getting test tube 1's clamp.
The working principle is as follows: firstly, the motor 5 drives the motor telescopic rod 6 to do linear motion, and the linear motion drives the movable fingers 3 to do relative opening and closing motion around respective rotating shafts through the inclined connecting rod 4 and the horizontal connecting rod 7. The elastic finger 2 is mounted on the movable finger 3, more specifically, the finger surface 201 of the elastic finger 2 is mounted on the movable finger 3 through two circular shafts 204 and fixed by a nut 203. Because the springs 202 are sleeved on the two circular shafts 204, when the movable fingers are closed, the elastic fingers 2 are driven to be closed, and after the finger surfaces 201 of the elastic fingers 2 contact the test tube 1, the finger surfaces 201 compress the springs 202 due to the interaction force, at this time, the springs 202 provide the clamping force for clamping the test tube 1, and the magnitude of the force can be initially adjusted by the nuts 203.
As shown in fig. 3, when the movable fingers 3 are further closed, the two movable fingers 3 will contact with each other, and no matter the motor rotates again, the clamping force is not increased, so that the test tube 1 is protected from being crushed due to the excessive clamping force.
The above embodiments are preferred embodiments of the present invention, and those skilled in the art can make variations and modifications to the above embodiments, therefore, the present invention is not limited to the above embodiments, and any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
