AI Technical Summary
Existing drug clamps are difficult to control precisely when gripping drugs, which can easily lead to damage or detachment of drug packaging, and they are also difficult to adapt to the size differences of different drug packaging boxes.
A drug delivery and clamping device was designed, which uses multiple sets of linkage assemblies and an electric push cylinder to drive a rotating adjustment plate. The clamping plate is closed synchronously by four sets of linkage assemblies, and the drug is clamped evenly from four directions to adapt to drug packaging boxes of different sizes.
It achieves uniform force distribution on medicines during the gripping process, avoiding damage, and at the same time improves the gripping range and accuracy of medicine packaging boxes of different sizes.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical handling clamp technology, specifically relating to a pharmaceutical delivery and clamping device. Background Technology
[0002] Current pharmaceutical production has evolved towards full mechanization and automation, with automated operations largely achieved through production lines. However, during drug transport, excessive gripping force from the grippers can damage the drug packaging, while insufficient gripping force can cause the drug to fall off during transport. Adjusting the gripping force requires precise control, and the size of different drug packaging boxes varies, making it difficult to ensure that every box is the same size. This means that the precision of drug gripping is hard to control, and current grippers cannot meet practical needs, requiring further improvements. Summary of the Invention
[0003] The present invention aims to solve the technical problems existing in the prior art and provide a medicine delivery and gripping device.
[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a medicine delivery and gripping device includes a mounting plate, the mounting plate being square, and a rotating adjustment plate provided on the lower surface of the mounting plate. The rotating adjustment plate is rotatably connected to the mounting plate. Four sets of connecting rod assemblies are arranged in a circular array between the mounting plate and the rotating adjustment plate. Each connecting rod assembly includes a long connecting rod, a short connecting rod, and a pull rod. The long connecting rod and the short connecting rod are both located on the lower side of the mounting plate, at the same height as the rotating adjustment plate. One end of the long connecting rod is rotatably connected to the corner of the mounting plate. The entire assembly is set along the edge of the mounting plate. One end of the short connecting rod is hinged to the rotating adjustment plate. The other two ends of the short connecting rod and the long connecting rod are hinged to each other. The pull rod is hinged to the middle position of the long connecting rod. A clamping plate is connected to the outer end of each pull rod. The rotating adjustment plate includes a rotating shaft extending to the upper surface of the mounting plate. Two push plates are symmetrically connected to the rotating shaft. Two electric push cylinders are hinged to the upper surface of the mounting plate. The fixed end of the electric push cylinder is rotatably connected to the upper surface of the mounting plate, and the extended end of the electric push cylinder is hinged to the push plate on the rotating shaft.
[0005] Preferably, a connecting plate is connected above the center of the mounting plate.
[0006] Preferably, the tie rods in the front and rear linkage assemblies are longer than the tie rods in the left and right linkage assemblies.
[0007] Preferably, the clamping plate and the corresponding tie rod are connected by a damped rotatable connection.
[0008] The beneficial effects of this utility model are as follows: By setting multiple sets of linkage assemblies, two electric push cylinders drive the rotating adjustment plate to rotate, which in turn drives four sets of linkage assemblies to pull the clamping plate to retract synchronously, thereby clamping the medicine from four directions simultaneously and avoiding damage to the medicine due to uneven force; the form of electric push cylinders driving four sets of linkage assemblies will continuously retract the clamping plate when the clamping plate is not clamping the medicine, thus facilitating the clamping of medicines in packaging boxes of different sizes and improving the gripping range of the clamp.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0014] Example: A drug delivery and gripping device, such as Figures 1-3 As shown, the device includes a mounting plate 1, which is square. A rotating adjustment plate 2 is provided on the lower surface of the mounting plate 1. The rotating adjustment plate 2 is rotatably connected to the mounting plate 1. Four sets of connecting rod assemblies are arranged in a circular array between the mounting plate 1 and the rotating adjustment plate 2. Each connecting rod assembly includes a long connecting rod 3, a short connecting rod 4, and a pull rod 5. The long connecting rod 3 and the short connecting rod 4 are both located on the lower side of the mounting plate 1, at the same height as the rotating adjustment plate 2. One end of the long connecting rod 3 is rotatably connected to the corner of the mounting plate 1, and the entire assembly is set along the edge of the mounting plate 1. The short connecting rod 4... One end of the short connecting rod 4 is hinged to the rotating adjustment plate 2. The other two ends of the short connecting rod 4 and the long connecting rod 3 are hinged to each other. The pull rod 5 is hinged to the middle position of the long connecting rod 3. Each pull rod 5 has a clamping plate 6 connected to its outer end. The rotating adjustment plate 2 includes a rotating shaft 7 extending to the upper surface of the mounting plate 1. Two push plates 8 are symmetrically connected to the rotating shaft 7. Two electric push cylinders 9 are hinged to the upper surface of the mounting plate 1. The fixed end of the electric push cylinder 9 is rotatably connected to the upper surface of the mounting plate 1, and the extended end of the electric push cylinder 9 is hinged to the push plate 8 on the rotating shaft 7.
[0015] A connecting plate 10 is connected above the center of the mounting plate 1; the tie rods 5 in the front and rear connecting rod assemblies are longer than the tie rods 5 in the left and right connecting rod assemblies; the clamping plate 6 and the corresponding tie rod 5 are connected by a damped rotating connection.
[0016] The principle of this utility model is as follows: In use, the clamp is connected to the robotic arm via the connecting plate 10. When it is necessary to move medicine, the robotic arm moves the clamp above the medicine to cover it, moving the medicine to the middle position formed by the four clamping plates 6. The two-ear electric push cylinders 9 extend to drive the rotating adjustment plate 2 to rotate. The rotation of the rotating adjustment plate 2 pulls the short connecting plate 10 to swing, thereby pulling the long connecting plate 10 inward, driving the pull rod 5 to pull the corresponding clamping plate 6, using the clamping plate 6 to clamp the medicine; it drives the four sets of linkage assemblies to pull the clamping plate 6 to retract synchronously, thereby clamping the medicine from four directions simultaneously, avoiding uneven force and damage to the medicine; the electric push cylinders 9 drive the four sets of linkage assemblies to continuously retract the clamping plate 6 when the medicine is not clamped, thereby facilitating the clamping of medicines in different sized packaging boxes and improving the gripping range of the clamp.
[0017] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
