Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a novel clamping claw and a battery clamping mechanism. Background Art

[0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycles and long storage time. They are not only widely used in portable electronic devices (such as mobile phones, digital cameras and laptops), but also widely used in large and medium-sized electric equipment such as electric vehicles, electric bicycles and power tools.

[0003] For square lithium-ion batteries, they need to be gripped by mechanical grippers during the production process, and then transferred and transported. Mechanical grippers play a role in the production process of lithium batteries, and are the mechanism that comes into contact with lithium batteries the most.

[0004] See also Figure 1 As shown, the existing mechanical gripper is a fixed mechanical gripper, which clamps lithium-ion batteries for transfer and transportation during the lithium-ion battery production process. If the mechanical gripper has not yet descended under the lithium-ion battery, the robot arm closes and clamps the battery, then the gripper will hit the side of the lithium-ion battery, that is, the mechanical gripper interferes with the side of the lithium-ion battery, causing battery damage and seriously affecting the safety of the battery (it may cause battery short circuit or other problems).

[0005] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Utility Model Content

[0027] See also Figures 1 to 5 , the utility model provides a novel clamping jaw, comprising a hollow clamping jaw box 7;

[0028] One end of the horizontally distributed clamping jaw box 7 is connected to the vertically distributed clamping jaw arm 4;

[0029] Inside the clamping jaw box 7, a transversely distributed spring 6 is provided;

[0030] The two ends of the spring 6 are connected to the clamping jaw box 7 and the movable end clamping jaw 5 respectively;

[0031] In the present utility model, in a specific implementation, a longitudinally distributed first threaded connection hole is respectively provided on the front and rear sides of the lower end of the clamping claw arm 4;

[0032] The front and rear side panels of the clamping jaw box 7 are respectively provided with a box through hole 700 at a position corresponding to each first threaded connection hole;

[0033] The clamp arm 4 is fixed to the clamp box 7 by two second screws 3;

[0034] The second screw 3 passes through the box body through hole 700 and is threadedly fixedly connected with the first threaded connection hole corresponding to the position.

[0035] It should be noted that, for the utility model, the clamp arm 4 is vertically distributed, with a mortise and tenon groove 401 (i.e., the recessed part of the mortise and tenon structure, also called mortise) on each of the lower sides, and each mortise and tenon groove has a threaded connection hole connected to the clamp box body 7 through a second screw 3.

[0036] In the present invention, in specific implementation, the spring 6 is a spiral spring.

[0037] In the present utility model, in specific implementation, two spring guide pillars 601 distributed laterally are arranged in the clamping jaw box 7;

[0038] The two spring guide pillars 601 are parallel to each other and symmetrically distributed front to back;

[0039] A spring 6 is sleeved on the outer side of each spring guide column 601;

[0040] The movable end clamping jaw 5 is provided with a spring receiving hole 501 at a position corresponding to each spring 6;

[0041] The spring accommodating hole 501 contains a spring 6 .

[0042] In specific implementation, the spring receiving hole 501 is a stepped hole;

[0043] The diameter of the stepped hole at one end facing the clamping jaw housing 7 is larger than the diameter of the other end away from the clamping jaw housing 7 .

[0044] It should be noted that the spring receiving hole 501 is a stepped hole in order to better fix the spring 6. The spring receiving hole 501 is used in conjunction with the spring guide column 601. The step of the stepped hole can compress the spring and keep the relative position of the spring unchanged.

[0045] It should be noted that, for the utility model, two stepped holes are provided inside the movable end clamp 5 for cooperation with the spring 6 and the spring guide column 601. The relative position (i.e., the lateral left and right position) of the movable end clamp 5 can be adjusted by compressing the spring 6 to realize the telescopic function of the clamp.

[0046] It should be noted that a spring guide column 601 is designed in the clamping jaw housing 7, and the spring guide column 601 is used to cooperate with the spring 6 and the clamping jaw stepped hole (spring receiving hole 501);

[0047] In specific implementation, the jaw box 7 is provided with a tenon 701 (i.e., the protruding part of the mortise and tenon structure, also called tenon) at a position corresponding to the two mortise and tenon grooves 401 (i.e., the recessed part of the mortise and tenon structure, also called tenon) on the lower side of the jaw arm 4, so that they cooperate with each other to form two sets of mortise and tenon structures, and a reliable connection is achieved between the jaw box 7 and the jaw arm 4 through the mortise and tenon structure.

[0048] In the present utility model, in specific implementation, a movable end clamping jaw avoiding opening slot 402 is provided at the lower middle part of the clamping jaw arm 4;

[0049] It should be noted that the movable end clamping jaw avoidance opening groove 402 can avoid the movable end clamping jaw 5 and does not affect the lateral movement of the movable end clamping jaw 5.

[0050] The movable end clamping jaw 5 is provided with a vertically distributed movable end stopper 502 at one end facing the clamping jaw box 7;

[0051] The movable end clamping jaw 5 transversely penetrates the movable end clamping jaw avoiding opening slot 402 at the lower part of the clamping jaw arm 4;

[0052] The movable end stopper 502 is located in the inner cavity of the clamping jaw housing 7;

[0053] In specific implementation, the vertical height of the movable end stopper 502 is greater than the vertical height of the movable end clamping jaw avoiding opening groove 402, and less than the vertical height of the inner cavity of the clamping jaw housing 7. Therefore, the movable end stopper 502 can be located inside the clamping jaw housing 7, and cannot flow out through the movable end clamping jaw avoiding opening groove 402 to cause a falling problem.

[0054] In specific implementation, the lateral width of the inner cavity of the clamp box 7 is greater than or equal to the overall lateral width of the movable end clamp 5, so that when the movable end clamp 5 is squeezed and contracted by external force, it can be partially or completely contracted into the inner cavity of the clamp box 7.

[0055] In the present utility model, in specific implementation, the clamping jaw box 7 is a box with openings on the top and right side;

[0056] A clamping box cover plate 2 is arranged on the top of the clamping box body 7 .

[0057] In specific implementation, a vertically distributed fixing protrusion 101 is provided at the top of the right end of the clamp box cover plate 2;

[0058] The fixing protrusion 101 is provided with two cover plate through holes 102 which are distributed transversely therethrough;

[0059] The lower end of the clamping claw arm 4 is provided with a second threaded connection hole distributed laterally at a position corresponding to each cover plate through hole 102;

[0060] The fixing protrusion 101 of the clamp box cover 2 is fixed to the clamp arm 4 by two first screws 1;

[0061] The first screw 1 passes through the cover plate through hole 102 transversely and is threadedly connected with the second threaded connection hole corresponding to the position.

[0062] It should be noted that the gripper box cover plate 2 is used to protect the internal mechanism of the gripper box body 7.

[0063] In the present utility model, in specific implementation, the first screw 1 and the second screw 3 are both hexagon socket screws.

[0064] In the present utility model, in a specific implementation, the movable end clamping claw 5 is made of polyoxymethylene (POM) material.

[0065] It should be noted that POM material has high wear resistance and long service life. At the same time, POM material has a lower density and lighter weight than aluminum alloy and steel, so it is easier to pop out and retract when combined with a spring. In addition, POM material is an insulating material, which is conducive to anti-static and avoids battery breakdown.

[0066] In the present invention, in a specific implementation, the movable end clamp 5 can be made of elastic material (such as rubber material), which can effectively avoid damage to the battery surface.

[0067] In the present invention, in a specific implementation, the end surface of the movable end clamping jaw 5 facing the object to be clamped (such as the square lithium-ion battery 10) includes an inclined surface and a vertical plane;

[0068] The inclined plane is above the vertical plane;

[0069] The height of the inclined surface gradually decreases as the distance from the clamping claw arm 4 gradually increases.

[0070] In a specific implementation, an elastic rubber layer is adhered to both the inclined surface and the vertical plane.

[0071] Furthermore, the thickness of the elastic rubber layer pasted on the inclined surface and the vertical plane is the same.

[0072] In the present utility model, in specific implementation, the upper end of the clamping claw arm 4 is provided with two manipulator connection threaded holes 403;

[0073] The gripper arm 4 is fixedly connected to the external manipulator via a third screw.

[0074] In specific implementation, the threaded holes 403 connecting the two manipulators correspond exactly to the two threaded holes reserved on the manipulators;

[0075] After the third screw passes through the robot arm connecting threaded hole 403, it is threadedly fixedly connected with the threaded hole on the robot arm at the corresponding position.

[0076] It should be noted that the third screw is also threadedly connected to the robot connecting threaded hole 403 .

[0077] It should be noted that the manipulator is an industrial production equipment with mature existing technology. For example, the YK1200X model robot produced by YAMAHA, or the LS20-804S robot produced by EPSON, and robots with spatial movement functions of other companies can be used. These robots are connected to the gripper provided by the utility model and provide the gripper with the function of moving in space (such as up and down movement, front and back movement, left and right movement, and rotational movement, etc.).

[0078] Based on the new clamp provided by the present invention, see Figure 5 As shown, the present invention also provides a battery clamping mechanism, comprising at least four novel clamping claws as described above;

[0079] At least four novel clamping jaws are respectively disposed on the left and right sides of the square lithium-ion battery 10 to be clamped.

[0080] In the present invention, in a specific implementation, the left front and rear ends of the square lithium-ion battery 10 are arranged correspondingly to the two new clamping claws;

[0081] The front and rear ends of the right side of the square lithium-ion battery 10 are arranged corresponding to the remaining two new clamping claws.

[0082] In order to more clearly understand the technical solution of the utility model, the working principle of the utility model is explained below.

[0083] When a square lithium-ion battery 10 is to be gripped and transported, four or more new clamps as described above are required, which are installed on the manipulator by screws through the screw holes above the clamp arms 4, so that the movable end clamps 5 of the new clamps of the utility model are located below the square lithium-ion battery 10, and the front end of the movable end clamps 5 (i.e., the end facing the battery) is kept at a certain distance from the side of the battery ( Figure 4 When the movable end clamping jaw 5 of the new clamping jaw interferes with the side of the lithium battery during the battery production process (i.e., the movable end clamping jaw 5 touches the side of the battery), the movable end clamping jaw 5 will automatically retract into the inside of the clamping jaw box 7 to avoid damaging the battery.

[0084] Compared with the prior art, the new clamping claw and battery clamping mechanism provided by the utility model have the following beneficial effects:

[0085] The structural design of the utility model is scientific and reasonable, and can conveniently and effectively avoid damage to the lithium battery caused by clamping and carrying of the clamping claws during the production process.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
