Technical Field

[0001] The invention belongs to the field of medical testing equipment, and in particular relates to a test cup moving device. Background Art

[0002] Currently, test cups are all clamped by electric grippers. Electric grippers are large in size, which is not conducive to space utilization. Electric grippers can only clamp test cups with large volumes. When the test cups are small, the use effect of electric grippers is relatively poor. In addition, electric grippers are expensive, which is not conducive to mass production of instruments. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a trial cup moving device with low cost and small space occupation.

[0004] The technical solution adopted in the present invention is:

[0005] A test cup moving device includes a moving base, upper and lower slides arranged on the moving base, and a picking and expanding sleeve fixedly arranged at the bottom of the upper and lower slides. The picking and expanding sleeve has an interference fit with the test cup, and a blanking fork is provided below the picking and expanding sleeve.

[0006] Furthermore, chamfers are provided on the lower end and four side edges of the picking-up expansion sleeve.

[0007] Furthermore, the movable base is fixedly connected to the test cup transverse moving belt, and is driven to move transversely by the test cup moving belt.

[0008] Furthermore, a test cup vertical moving belt is provided on the movable base, and the upper and lower slides are fixedly connected to the test cup vertical moving belt and are driven to move up and down by the test cup vertical moving belt.

[0009] Furthermore, the unloading fork includes a fork base, a fork driving device fixedly mounted on the fork base, and a positioning fork mounted on the fork driving device. Fins for cooperating with the positioning fork are provided on both sides of the top of the test cup.

[0010] Furthermore, the fork driving device is an electromagnet.

[0011] The positive effects of the present invention are:

[0012] The present invention utilizes the interference fit between the pick-up expansion sleeve and the test cup to realize the pick-up work of the test cup, and simultaneously utilizes the shifting fork device to shift the test cup off the pick-up expansion sleeve to realize the transfer work of the test cup, completely replacing the work of the electric clamp. The whole device has a simple structure and occupies a small space, which is conducive to the mass production of the instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the present invention;

[0015] Figure 3 It is a schematic diagram of the structure of the blanking fork of the present invention. DETAILED DESCRIPTION

[0016] Example 1

[0017] As attached Figure 1 、 2 As shown, the test cup moving device of this embodiment includes a laterally movable mobile base 2, upper and lower slides 4 arranged on the mobile base 2, and a picking sleeve 5 fixedly arranged at the bottom of the upper and lower slides 4. The picking sleeve 5 has an interference fit with the test cup. A discharge fork is provided below the picking sleeve 5 and at the target position for the test cup to be moved. The discharge fork is used to remove the test cup from the picking sleeve 5 so that the test cup falls into the target position.

[0018] As attached Figure 3 As shown, the unloading fork includes a fork base, a fork driving device 6 fixedly mounted on the fork base, and a positioning fork 7 mounted on the fork driving device 6. Fins for cooperating with the positioning fork 7 are provided on both sides of the top of the test cup.

[0019] Preferably, the fork driving device 6 is an electromagnet.

[0020] Example 2

[0021] This embodiment is a further limitation of the embodiment 1. In this embodiment, the lower end and four side edges of the picking sleeve 5 are provided with chamfers.

[0022] Example 3

[0023] This embodiment is a further limitation of the embodiment 1. In this embodiment, the movable base 2 is fixedly connected to the test cup transverse moving belt 1 and is driven to move transversely by the test cup moving belt 1.

[0024] The movable base 2 is provided with a test cup vertical moving belt 3 , and the upper and lower slides 4 are fixedly connected to the test cup vertical moving belt 3 and are driven to move up and down by the test cup vertical moving belt 3 .

[0025] The picking process of the present invention is as follows: the picking expansion sleeve 5 is interference-fitted with the test cup to lift and transfer the test cup. The lower end and four side edges of the picking expansion sleeve 5 are chamfered to facilitate insertion and positioning of the expansion sleeve; the four side chamfers are equivalent to air leakage grooves, which can allow the gas in the test cup to escape when the expansion sleeve is inserted into the test cup.

[0026] The process of placing the test cup into the target position is as follows: after the expansion sleeve is picked up and the test cup is driven into the work station block, the electromagnet drives the positioning fork 7 to move forward to the upper part of the test cup to block the upper edge of the test cup, and the expansion sleeve is picked up and moved upward. The test cup cannot move upward due to being blocked by the positioning fork, and falls off the expansion sleeve and remains in the target work station of the test cup.

[0027] Compared with the traditional electric gripper, the present invention has a simple overall structure, low manufacturing cost, and occupies less space, which is conducive to improving the space utilization rate of the entire equipment.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
