Description

Technical Field

[0001] The utility model belongs to the technical field of single crystal silicon rod processing, and specifically relates to a single crystal silicon square rod grabbing device. Background Art

[0002] The rapid development of the solar energy industry has led to a substantial increase in the demand for monocrystalline silicon wafers, which are the main raw material. When loading monocrystalline silicon slices, a gripping device is required to clamp the monocrystalline silicon square rods and transfer them to the processing station.

[0003] After searching, the prior art discloses an automatic silicon rod gripping device and lifting equipment (application number 202021053644.4), including: a scissors assembly, which is divided into a clamping end and a clamping control end for clamping silicon rods; a cylinder, which is arranged at the clamping control end, and is used to control the opening of the opening between the first arm and the second arm of the clamping end; a tension spring, which is arranged at the clamping control end, and is used to close the opening between the first arm and the second arm of the clamping end; an anti-loosening assembly for preventing the clamped silicon rod from slipping, and the two air holes of the anti-loosening assembly are respectively connected to the ports of the exhaust pipe and the intake pipe of the cylinder.

[0004] The automatic silicon rod gripping device disclosed in the above-cited document clamps the single crystal silicon square rod through two chucks 14. However, in actual application, the surface of the single crystal silicon square rod may be uneven. The existing chucks are usually an integral clamping plate structure, which may cause an overhead gap between the clamping plate and the single crystal silicon square rod when clamping the single crystal silicon square rod, thereby causing the clamping force of the clamping plate on the single crystal silicon square rod to be unevenly concentrated, affecting the clamping stability or causing damage to the single crystal silicon square rod.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the technical problem of uneven clamping force concentration, the basic concept of the technical solution adopted by the utility model is:

[0007] A single crystal silicon square rod grabbing device, comprising:

[0008] A lifting arm, the lifting arm is installed on the lifting device, and a bottom plate is fixedly installed at the bottom of the lifting arm;

[0009] The buffer assembly includes a telescopic rod and a spring 1, the top of the telescopic rod is fixedly connected to the bottom of the base plate, and the spring 1 is arranged outside the circumference of the telescopic rod;

[0010] The clamping mechanism includes a cylinder assembly and a piston rod, the top of the cylinder assembly is fixedly connected to one end of the bottom of the telescopic rod, and the piston rod is arranged on the cylinder assembly;

[0011] The splint structure is composed of a plurality of splint units, and the splint units are fixedly installed on the piston rod.

[0012] As a preferred embodiment of the present utility model, four groups of buffer components are provided, and the four groups of buffer components are respectively fixedly installed at two sides of the bottom of the base plate.

[0013] As a preferred embodiment of the utility model, the clamping mechanism is provided with two groups, the two groups of clamping mechanisms are respectively arranged at two sides below the bottom plate, and the two cylinder assemblies are respectively fixedly installed between the bottoms of the two telescopic rods on the same side.

[0014] As a preferred embodiment of the utility model, the piston rods are arranged on the side where the two cylinder assemblies are close to each other, and the piston rods are installed on the cylinder assemblies in a linear array with uniform intervals and sliding fit.

[0015] As a preferred embodiment of the present utility model, the clamping plate unit is arranged on the side of the piston rod away from the cylinder assembly, and the clamping plate unit and the piston rod are installed in a one-to-one corresponding manner.

[0016] As a preferred embodiment of the present utility model, an anti-skid pad is fixedly installed on one end of the clamping plate unit away from the piston rod, and the anti-skid pad is made of silicone material.

[0017] As a preferred embodiment of the utility model, the piston rod includes a main rod body and a connecting rod. The main rod body is slidably mounted on the cylinder assembly. A slide groove is provided at one end of the main rod body away from the cylinder assembly. The connecting rod is slidably connected between the inner walls of the slide groove at one end close to the main rod body, and the end of the connecting rod away from the main rod body is fixedly connected to the splint unit by screws. A spring 2 is provided on the outer side of the circumference of the connecting rod between the main rod body and the splint unit.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] Through the clamping mechanism that is set up, when the device is used, the two groups of clamping mechanisms are moved to the two sides of the single crystal silicon square rod, and then the cylinder assembly is controlled to intake air, so that multiple groups of piston rods are pushed out, so that the clamping plate units clamp from both sides of the single crystal silicon square rod. The segmented clamping plate structure in which multiple clamping plate units are independently set up has a better clamping effect on the single crystal silicon square rod compared to the overall clamping plate structure, and ensures that the clamping force of the clamping plate structure on the single crystal silicon square rod is evenly dispersed, avoiding factors such as differences in surface flatness of the single crystal silicon square rod or deformation and damage of the clamping plate surface, which lead to overhead gaps between the clamping plates and the single crystal silicon square rods, thereby causing uneven concentration of clamping force to affect the clamping stability or damage the single crystal silicon square rod; the setting of the anti-slip pad further improves the clamping firmness and has a certain protective effect to prevent the single crystal silicon square rod from slipping and being damaged.

[0020] The main rod body and the connecting rod are slidably connected. Under the elastic action of spring 2, when the clamping plate unit contacts the single crystal silicon square rod, the connecting rod contracts until the connecting rod contacts the inner end of the slide groove close to one end of the main rod body and stops sliding, thereby ensuring the clamping stability when clamping the single crystal silicon square rod and playing a good buffering role, avoiding the rigid collision between the clamping plate unit and the single crystal silicon square rod, which may cause the single crystal silicon square rod to be broken or damaged.

[0021] The setting of the buffer component, through the cooperation of the telescopic rod and the spring, plays an elastic role, thereby preventing the cylinder component from being damaged by collision when the clamping mechanism descends to clamp the single crystal silicon square rod.

[0022] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0031] A single crystal silicon square rod grabbing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, including:

[0032] A lifting arm 10, the lifting arm 10 is installed on the lifting device, and a bottom plate 11 is fixedly installed at the bottom of the lifting arm 10;

[0033] The buffer assembly 20 includes a telescopic rod 21 and a spring 22. The top of the telescopic rod 21 is fixedly connected to the bottom of the bottom plate 11, and the spring 22 is arranged outside the circumference of the telescopic rod 21.

[0034] The clamping mechanism 30 includes a cylinder assembly 31 and a piston rod 32. The top of the cylinder assembly 31 is fixedly connected to one end of the bottom of the telescopic rod 21, and the piston rod 32 is arranged on the cylinder assembly 31;

[0035] The clamping plate structure is composed of a plurality of clamping plate units 33 , and the clamping plate units 33 are fixedly mounted on the piston rod 32 .

[0036] like Figure 1-Figure 3 As shown, four groups of buffer components 20 are provided, and the four groups of buffer components 20 are respectively fixedly installed at two sides of the bottom of the bottom plate 11.

[0037] Its function is that the setting of the buffer assembly 20, through the cooperation of the telescopic rod 21 and the spring 1 22, plays an elastic role, so as to avoid the cylinder assembly 31 from being damaged due to collision when the clamping mechanism 30 descends to clamp the single crystal silicon square rod.

[0038] like Figure 1-Figure 3 As shown, two groups of clamping mechanisms 30 are provided, and the two groups of clamping mechanisms 30 are respectively provided at two sides below the bottom plate 11, and two cylinder assemblies 31 are respectively fixedly installed between the bottoms of two telescopic rods 21 on the same side.

[0039] like Figure 3-Figure 4 As shown, the piston rods 32 are arranged on the side where the two cylinder assemblies 31 are close to each other, and the piston rods 32 are installed on the cylinder assemblies 31 in a linear array with uniform intervals and sliding fit.

[0040] like Figure 4-Figure 5 As shown, the clamping plate unit 33 is arranged on the side of the piston rod 32 away from the cylinder assembly 31, and the clamping plate unit 33 and the piston rod 32 are installed in a one-to-one corresponding manner.

[0041] like Figure 5 As shown, an anti-skid pad 34 is fixedly mounted on one end of the clamping plate unit 33 away from the piston rod 32 , and the anti-skid pad 34 is made of silicone material.

[0042] Its function is that, through the provided clamping mechanism 30, when the device is used, two groups of clamping mechanisms 30 are moved to both sides of the single crystal silicon square rod, and then the cylinder assembly 31 is controlled to intake air, so that multiple groups of piston rods 32 are pushed out, so that the clamping plate units 33 clamp from both sides of the single crystal silicon square rod. The segmented clamping plate structure with multiple clamping plate units 33 independently provided has a better clamping effect on the single crystal silicon square rod compared to the overall clamping plate structure, and ensures that the clamping force of the clamping plate structure on the single crystal silicon square rod is evenly dispersed, avoiding factors such as differences in surface flatness of the single crystal silicon square rod or deformation and damage of the clamping plate surface, resulting in overhead gaps between the clamping plate and the single crystal silicon square rod, thereby causing uneven concentration of clamping force to affect the clamping stability or damage the single crystal silicon square rod; the provision of the anti-slip pad 34 further improves the clamping tightness, and has a certain protective effect to prevent the single crystal silicon square rod from slipping and being damaged.

[0043] like Figure 5 As shown, the piston rod 32 includes a main rod body 321 and a connecting rod 323. The main rod body 321 is slidably mounted on the cylinder assembly 31. A slide groove 322 is provided at one end of the main rod body 321 away from the cylinder assembly 31. The connecting rod 323 is slidably connected between the inner walls of the slide groove 322 at one end close to the main rod body 321. The connecting rod 323 is fixedly connected to the splint unit 33 at one end away from the main rod body 321 by screws. A spring 2 324 is provided on the outer side of the circumference of the connecting rod 323 between the main rod body 321 and the splint unit 33.

[0044] Its function is that the main rod body 321 and the connecting rod 323 are slidably connected. Under the elastic action of the second spring 324, when the clamping unit 33 contacts the single crystal silicon square rod, the connecting rod 323 contracts until the connecting rod 323 contacts the inner end of the slide groove 322 close to one end of the main rod body 321 and stops sliding, thereby ensuring the clamping stability when clamping the single crystal silicon square rod and playing a good buffering role, avoiding the rigid collision between the clamping unit 33 and the single crystal silicon square rod, which may cause the single crystal silicon square rod to be broken or damaged.

[0045] Working principle: when the device is in use, the lifting device controls the lifting arm 10 to descend, so that the two sets of clamping mechanisms 30 move to the two sides of the single crystal silicon square rod, and then controls the cylinder assembly 31 to intake air, so that the piston rod 32 is pushed out to make the clamping unit 33 clamp the single crystal silicon square rod from both sides of the single crystal silicon square rod. When the clamping unit 33 contacts the single crystal silicon square rod, the setting of the spring-retractable connecting rod 323 plays a buffering and protective role. After clamping, the lifting device controls the lifting arm 10 to rise and move the single crystal silicon square rod to the processing position.
