[0002] In automated equipment, especially ophthalmic instruments, there is often a need to hold samples in parallel, which requires the use of servo parallel grippers to hold the products in parallel.

[0003] Meanwhile, a parallel gripper with application number CN202022334159.0 includes a main body, a gripper slide rail, a gripper limiter, a gripper, and a piston. The piston is disposed within the main body, the gripper slide rail is disposed at the lower end of the main body, and a groove is provided at the lower end of the gripper slide rail. The gripper limiter is slidably connected in the groove, and the gripper is disposed at the lower end of the gripper limiter. A piston shaft is provided at one end of the piston, and a swing rod is rotatably connected to the piston shaft. A gripper shaft is provided at one end of the gripper limiter, and the piston shaft and the gripper shaft are rotatably connected through the swing rod.

[0004] However, the following problems were found in the implementation of the relevant technology: the gripping structure of the gripper is set to a fixed length, which results in a fixed gripping range for the sample. It is inconvenient to adjust the extension and retraction of the gripper according to the size of the sample, which reduces the practicality of use. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a servo parallel gripper for sample preprocessing, which has the advantage of conveniently adjusting the gripper length to meet the clamping requirements of samples of different sizes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a servo parallel gripper for sample preprocessing, comprising a parallel gripper drive source, wherein the power output end of the parallel gripper drive source is poweredly connected to two gripper linkage plates, a second clamping plate is connected to one side of each of the two gripper linkage plates, a second silicone pad is connected to one side of each of the two second clamping plates, and two adjustment components and two limiting components are respectively provided on the two gripper linkage plates.

[0007] The surfaces of the two adjustment components are respectively connected to the surfaces of the two gripper linkage plates to adjust the clamping length of the two gripper linkage plates;

[0008] The surfaces of the two limiting components are respectively connected to the surfaces of the two gripper linkage plates to limit the movement of the two adjusting components.

[0009] Preferably, each of the two adjustment components includes a rotating rod, a first silicone pad, and four fixed rods. The two rotating rods are rotatably disposed on the inner side of the two gripper linkage plates. One end of each of the two rotating rods is connected to an adjusting screw. The surfaces of the two adjusting screws are threadedly connected to a first clamping plate through a screw nut. The two first silicone pads are respectively disposed on one side of the two first clamping plates. Each pair of fixed rods is disposed on one side of each gripper linkage plate. The other end of each rotating rod is connected to a handle. One end of each pair of fixed rods is connected to a fixed plate.

[0010] Preferably, the surfaces of each pair of fixing rods are slidably attached to the inner side of each of the first clamping plates.

[0011] Preferably, the surface of each pair of fixing rods is connected to the inner side of each of the second clamping plates.

[0012] Preferably, one end of each adjusting screw is rotatably connected to one side of each fixed plate via a bearing.

[0013] Preferably, each of the two limiting components includes four limiting rods and rubber pads. Each set of four limiting rods is disposed on the other side of each gripper linkage plate. Each set of four limiting rods is slidably connected to a limiting plate. Each set of two rubber pads is disposed on one side of the two limiting plates. Each set of four limiting rods is fitted with a retraction spring. Each set of four limiting rods is connected to a positioning plate at one end.

[0014] Preferably, one side of each of the two rubber pads is abutted against one side of each of the two handles.

[0015] Preferably, the two ends of each of the four retraction springs are respectively connected to the other side of each gripper linkage plate and one side of each positioning plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model allows the first clamping plate to move horizontally by rotating the adjusting screw, facilitating the adjustment of the distance between the first and second clamping plates. This adapts to clamping samples of different sizes. The first and second silicone pads enhance the friction between the clamping plate and the sample, thereby improving clamping stability. The corresponding fixing rod supports the first clamping plate, preventing it from wobbling. Furthermore, the fixing plate's limiting effect effectively prevents the first clamping plate from detaching from the adjusting screw surface, improving ease of use.

[0018] 2. This utility model uses the contraction action of the spring to ensure that the limiting plate and the rubber pad always exert a strong compressive limiting force on the surface of the handle. The friction of the rubber pad, combined with the compressive force, completes the limiting of the handle, preventing the handle and the rotating rod from rotating randomly, thus improving the stability of use. In addition, the positioning plate also limits the limiting plate, preventing the limiting plate from detaching from the surface of the limiting rod. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5As shown, this utility model provides a servo parallel gripper for sample preprocessing, including a parallel gripper drive source 1. The power output end of the parallel gripper drive source 1 is powered to connect two gripper linkage plates 4. A second clamping plate 5 is connected to one side of each of the two gripper linkage plates 4. A second silicone pad 6 is connected to one side of each of the two second clamping plates 5. Two adjustment components 2 and two limiting components 3 are respectively provided on the two gripper linkage plates 4.

[0030] The surfaces of the two adjustment components 2 are respectively connected to the surfaces of the two gripper linkage plates 4 to adjust the clamping length of the two gripper linkage plates 4;

[0031] The surfaces of the two limiting components 3 are respectively connected to the surfaces of the two gripper linkage plates 4 to limit the two adjusting components 2.

[0032] Specifically, each of the two adjustment components 2 includes a rotating rod 21, a first silicone pad 24, and four fixing rods 25. The two rotating rods 21 are respectively rotatably disposed on the inner side of the two gripper linkage plates 4. One end of each of the two rotating rods 21 is connected to an adjusting screw 22. The surfaces of the two adjusting screws 22 are threadedly connected to a first clamping plate 23 through a screw nut. The two first silicone pads 24 are respectively disposed on one side of the two first clamping plates 23. Each pair of fixing rods 25 is respectively disposed on one side of each gripper linkage plate 4. The other end of each rotating rod 21 is connected to a handle 26. One end of each pair of fixing rods 25 is connected to a fixing plate 27.

[0033] Furthermore, the surfaces of each pair of fixing rods 25 are slidably attached to the inner side of each of the first clamping plates 23.

[0034] Furthermore, the surfaces of each pair of fixing rods 25 are respectively connected to the inner side of each of the second clamping plates 5.

[0035] It is worth noting that one end of each of the adjusting screws 22 is rotatably connected to one side of each of the fixed plates 27 via a bearing.

[0036] It is worth noting that both of the limiting components 3 include four limiting rods 31 and rubber pads 33. Each set of four limiting rods 31 is respectively disposed on the other side of each gripper linkage plate 4. Each set of four limiting rods 31 is slidably connected to a limiting plate 32. Each set of two rubber pads 33 is respectively disposed on one side of the two limiting plates 32. Each set of four limiting rods 31 is fitted with a contraction spring 34. Each set of four limiting rods 31 is connected to a positioning plate 35 at one end.

[0037] It is worth mentioning that one side of each of the two rubber pads 33 is respectively attached to one side of each of the two handles 26.

[0038] It is worth emphasizing that the two ends of each of the four retraction springs 34 are respectively connected to the other side of each of the gripper linkage plates 4 and one side of each of the positioning plates 35.

[0039] The parallel gripper drive source 1 and gripper linkage plate 4 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0040] Working principle: First, install the parallel gripper drive source 1 with the external structure. Then, according to the required sample length, the user pulls the limiting plate 32 outward. The operation can be adjusted according to the number of staff, either pulling the two limiting plates 32 separately or simultaneously. At this time, the rubber pad 33 separates from the handle 26, and the handle 26 loses its strong squeezing force. Rotating the handle 26 drives the rotating rod 21 and the adjusting screw 22 to rotate, which in turn drives the corresponding first clamping plate 23 to move horizontally, thereby adjusting the working distance between the first clamping plate 23 and the second clamping plate 5, and then clamping as needed. For longer samples, the grip is more secure, improving the flexibility of use. When the adjusting screw 22 moves the first clamping plate 23 horizontally, the first clamping plate 23 will slide on the surface of the corresponding fixing rod 25, thus preventing the first clamping plate 23 from shaking and improving the stability of the sample clamping. After adjusting the position of the first clamping plate 23, the corresponding limiting plate 32 is released. Then, under the strong pulling action of the corresponding contraction spring 34, the limiting plate 32 and the rubber pad 33 will rebound and reset to be tightly attached to the surface of the handle 26 again. Thus, the friction of the rubber pad 33 limits the handle 26 and prevents the handle 26 from rotating randomly.
