DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status of the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] See also Figure 1 and Figure 5 , Figure 1 This is a first overall schematic diagram of the clamping mechanism provided by the embodiment of the present invention, that is, a schematic diagram viewed from the right side of the clamping mechanism. Figure 6 It is a schematic diagram of the driving member 10 provided in an embodiment of the present utility model.

[0028] The present invention proposes a clamping mechanism, which includes: a base 30, a driving member 10, and a clamping jaw assembly 20. The driving member 10 is arranged on the base 30, and a first driving part 110a and a second driving part 110b are provided on the driving member 10. The clamping jaw assembly 20 includes a connecting seat 220 connected to the base 30 and a clamping jaw member 210 movably arranged on the connecting seat 220; the first driving part 110a is drivingly connected to the clamping jaw member 210, and the second driving part 110b is drivingly connected to the connecting seat 220.

[0029] In this embodiment, the clamping mechanism is provided with a first driving part 110a and a second driving part 110b. The first driving part 110a is driven and connected to the clamping claw member 210, driving the clamping part of the clamping claw member 210 to open and close to clamp the product 50. The second driving part 110b is driven and connected to the connecting seat 220, driving the connecting seat 220 to move up and down to lift the position of the product 50, that is, only the clamping mechanism needs to be driven to realize the two functions of grabbing the product 50 and lifting the product 50. The clamping mechanism integrates the clamping and lifting functions of the product 50 into one, thereby increasing the function of the clamping mechanism. At the same time, compared with the existing technical solutions, the two functions of grabbing the product 50 and lifting the product 50 are realized without adding an additional power device, thereby reducing manufacturing costs and reducing the space occupied by the clamping mechanism, thereby improving the functional diversity of the clamping mechanism and fully simplifying the structural design of the clamping mechanism.

[0030] In one embodiment, please refer to Figure 2and Figure 8 , Figure 2 This is a second overall schematic diagram of the clamping mechanism provided by the embodiment of the utility model. Figure 8 It is a schematic diagram of the clamping jaw assembly 20 provided by an embodiment of the present invention, wherein the clamping jaw members 210 are provided with two groups, the two groups of the clamping jaw members 210 are arranged opposite to each other and the two groups of the clamping jaw members 210 are usually kept parallel to each other, and the first driving part 110a is used to drive the clamping parts of the two groups of the clamping jaw members 210 to approach each other; the connecting seat 220 is provided with a reset member 220b for driving the clamping parts of the two groups of the clamping jaw members 210 away from each other, and the reset member 220b is provided on the connecting seat 220. Furthermore, the two groups of the clamping jaws 210 are L-shaped as a whole, the upper ends of the two groups of the clamping jaws 210 are bent and kept parallel, and the upper ends of the two groups of the clamping jaws 210 are provided with clamping blocks 211. The clamping blocks 211 at the upper ends of the two groups of the clamping jaws 210 cooperate to form a clamping portion. When the two groups of the clamping jaws 210 are under the action of the second driving part 110b, the two groups of the clamping jaws 210 can rotate toward each other to form a clamping posture. The middle part of the two groups of the clamping jaws 210 is provided with a connecting piece 213, and the two groups of the clamping jaws 210 are connected to the connecting seat 220 via the connecting piece 213. And by providing a reset piece 220b, the clamping jaws 210 can be automatically reset under the action of the reset piece 220b, making the clamping mechanism more automated and intelligent.

[0031] In addition, the clamping jaw 210 can also be slidably set on the connecting seat 220; at the same time, the first driving part 110a can also be set as a driving groove structure, so that the clamping part of the clamping jaw 210 can be opened and closed without setting the reset part 220b.

[0032] See also Figure 6 and Figure 7 The two groups of clamping jaws 210 are also provided with a blocking piece 212, and the reset member 220b includes two torsion springs, which abut against the blocking piece 212. When the two torsion springs are compressed, they can generate a reset elastic force, thereby driving the two groups of clamping jaws 210 to reset.

[0033] Please also refer to Figure 1 、 Figure 2 、 Figure 3 , Figure 3This is a schematic diagram of the clamping mechanism provided by an embodiment of the present invention without the lifting bracket 230. The clamping jaw assembly 20 includes a first sliding assembly 41 and a lifting bracket 230. The first sliding assembly 41 includes a first slider 41a connected to the connecting seat 220 and a first guide rail 41b connected to the lifting bracket 230. The first slider 41a is slidably connected to the first guide rail 41b. The side wall of the connecting seat 220 is provided with a groove along the vertical direction. The first slider 41a can move in the groove. The first guide rail 41b is fixedly connected to the lifting bracket 230. The first sliding assembly 41 can drive the connecting seat 220 and the clamping jaw 210 to move up and down on the lifting bracket 230, thereby realizing the function of the clamping jaw 210 to lift the position of the product 50 when clamping the product 50.

[0034] See also Figure 5 and Figure 6 , Figure 5 Schematic diagram of the driving member 10 provided in an embodiment of the present utility model. Figure 6 It is the third overall schematic diagram of the clamping mechanism provided by an embodiment of the present utility model. As an implementation mode, the first driving part 110a includes a lifting driving surface, a first lifting driving parallel surface and a second lifting driving parallel surface located on both sides of the lifting driving surface, and the lifting driving surface is set to be an inclined surface inclined toward the second lifting driving parallel surface, and at least a part of the plane of the first lifting driving parallel surface gradually widens toward the lifting driving surface, that is, by setting the lifting driving surface as an inclined surface, the lifting driving surface can drive the position of the clamping claw assembly 20 to rise, thereby realizing the function of the clamping assembly to lift the position of the product 50.

[0035] Furthermore, the second driving portion 110b includes two relatively arranged rotating driving surfaces, and the two relatively arranged rotating driving surfaces are located on both sides of the first lifting driving parallel surface. When the clamping jaw assembly 20 rolls in contact with the lifting driving surface, it is lifted by the lifting driving surface. When the clamping jaw assembly 20 rolls in contact with the two rotating driving surfaces, the two relatively arranged clamping jaw members 210 rotate toward each other to perform a clamping action, thereby driving the clamping jaw members 210 to perform the action of clamping the product 50, thereby realizing the function of the clamping mechanism to clamp the product 50.

[0036] As an implementation, see again Figure 5 The lifting drive surface is located in the middle of the driving member 10, and the driving member 10 includes a first side portion, which is connected to the first lifting drive parallel surface and two rotating drive surfaces. The first side portion is located at one end of the driving member 10, and the lifting drive surface is inclined upward in a direction away from the first side portion.

[0037] Furthermore, the two rotating drive surfaces are located in the middle of the driving member 10, the interval between the two rotating drive surfaces gradually widens in the direction away from the first side portion and the two rotating drive surfaces form an inclined surface on the side surface of the driving member 10, and the spacing between the two rotating drive surfaces gradually increases in the direction away from the clamping member 210. When the two clamping members 210 move on the surface of the two rotating drive surfaces of the driving member 10, the two rotating drive surfaces drive the two clamping members 210 to rotate toward each other to perform a clamping action, so that the clamping mechanism can realize the function of clamping the product 50.

[0038] As a preference, the two rotating drive surfaces are closer to the first side portion than the lifting drive surface, so that the driving member 10 first performs the action of clamping the product 50 and then lifts the position of the product 50.

[0039] See also Figure 6 and Figure 7 In one embodiment, the clamping portion includes a clamping block 211. The clamping block 211 is made of a non-metallic material, and a V-shaped groove, a C-shaped groove, or an arcuate groove is formed in the middle of each clamping block 211. The two clamping blocks 211 cooperate with each other to form the clamping portion. The V-shaped groove, C-shaped groove, or arcuate groove can be adaptively replaced to correspond to different product shapes. The V-shaped groove and the arcuate groove are suitable for cylindrical batteries, and the C-shaped groove is suitable for square batteries.

[0040] See also Figure 3 , Figure 3 This is a schematic diagram of the clamping mechanism provided by an embodiment of the present invention without the lifting bracket 230. The clamping mechanism also includes a second sliding component 42 arranged on the base 30. The second sliding component 42 includes a second guide rail 42b and a second slider 42a. The second guide rail 42b and the second slider 42a are slidably connected. The second guide rail 42b is connected to the base 30 and extends along the length direction of the base 30. The second slider 42a is connected to the driving member 10. By setting the second sliding component 42, the driving member can be reciprocated along the length direction of the base 30. When the driving member 10 moves on the base 30, the driving member 10 can drive the clamping claw assembly 20 to realize the function of clamping and lifting the position of the product 50.

[0041] See also Figure 4 , Figure 4The figure is a schematic diagram of a connecting base 220 provided in an embodiment of the present invention. As an embodiment, the connecting base 220 includes a connecting body 220a and two rotating shafts 220c. The connecting body 220a is provided with four through holes. The two rotating shafts 220c each pass through the through holes and are disposed on the connecting body 220a. Two sets of the clamping jaws 210 are respectively connected to the two rotating shafts 220c. The connecting base 220 includes a cotter pin 220e and four retaining rings 220d. Each rotating shaft 220c is sleeved with the retaining ring 220d and the torsion spring 220b. At least one end of the torsion spring 220b is fixed by the cotter pin 220e. The retaining rings 220d are located on both sides of the torsion spring 220b. The reset member 220b is disposed on the rotating shaft 220c to enable the clamping jaw 210 to rotate and reset around the rotating shaft 220c.

[0042] See also Figure 3 Furthermore, the clamping jaw assembly 20 includes a contact member 240, and the contact member 240 includes a follower 240a and two universal balls. The follower 240a is connected to the connecting seat 220, and the two universal balls are respectively connected to the two groups of clamping jaw members 210. The universal balls realize rolling contact between the clamping jaw assembly 20 and the two side surfaces of the driving member 10, thereby driving the two clamping jaw members 210 of the clamping jaw assembly 20 to rotate toward each other to perform the action of clamping the product 50, and then the follower 240a realizes rolling contact between the clamping jaw assembly 20 and the upper surface of the driving member 10, thereby driving the position of the clamping jaw assembly 20 to lift. By setting the follower to roll in contact with the first driving part of the driving member, the clamping jaw assembly is driven to lift, and by setting the two universal balls to roll in contact with the second driving part of the driving member, the clamping jaw member can clamp the product.

[0043] The present utility model also proposes a processing equipment, including a power source and the clamping mechanism described in any one of the above embodiments, the power source is connected to the driving member 10, the power source is any one or more of a cylinder, a piston, and a motor, and the power source is used to drive the driving member 10 to move on the base 30.

[0044] Specifically, the power source can drive the driving member 10 to move back and forth along the length direction of the second guide rail 42b. When the power source drives the driving member 10 to move in the direction close to the clamping jaw assembly 20, the universal wheel 240b rolls along the surface of the second driving part 110b of the driving member 10, that is, the two side surfaces of the driving member 10 roll, and the follower 240a rolls along the surface of the first driving part 110a of the driving member 10, that is, the upper surface of the driving member 10 rolls. Since the two rotating drive surfaces are closer to the first side portion than the lifting drive surface, the universal wheel 240b of the clamping jaw assembly 20 reaches the inclined surface of the driving member 10 faster than the follower 240a, and when the universal wheel 240b rolls to two oppositely arranged rotating drive surfaces, the two clamping jaw members 210 are driven by the two rotating drive surfaces to rotate toward each other, so that the two clamping jaw members 210 are close to each other to clamp the product 50. The power source continues to drive the driving portion to move, and when the follower 240a rolls to the lifting drive surface, the clamping jaw assembly 20 moves upward on the inclined surface formed by the lifting drive surface and is lifted by the lifting drive surface, thereby lifting the position of the product 50. The above process is the working process of the clamping mechanism clamping the product 50. When the power source drives the driving member 10 to move in a direction away from the clamping jaw assembly 20, the follower 240a moves downward along the lifting drive surface, and the position of the clamping jaw assembly 20 and the product 50 is lowered. When the power source drives the driving member 10 to continue to move in a direction away from the clamping jaw assembly 20, the universal wheel 240b rolls along the rotating drive surface, and the two clamping jaw members 210 move away from each other under the action of the reset member 220b, and the two clamping jaw members 210 release the product 50.

[0045] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0046] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
