The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] like Figure 1-Figure 9 As shown, the utility model provides a battery module entry jaw quick-change mechanism. In practical applications, two jaw quick-change mechanisms of the present application are usually arranged opposite to each other, a workbench is provided between the two jaw quick-change mechanisms, and the battery module is placed on the workbench. When working, the two jaw quick-change mechanisms and the jaws provided thereon move in relative directions, and the jaws are used to grasp, clamp, and move the battery module.

[0024] The clamping jaw quick-change mechanism of the present application includes a mounting plate, a clamping jaw docking assembly, a clamping jaw assembly, and a variable pitch drive component, wherein the mounting plate can be fixedly mounted on any carrier on the work assembly line. The direction in which the output end of the variable pitch drive component moves toward the clamping jaw assembly is defined as the X-axis direction. In the present embodiment, the mounting plate includes two mounting vertical plates 11 and one mounting horizontal plate 12, and the two mounting vertical plates 11 and one mounting horizontal plate are arranged in an H shape, that is, the two mounting vertical plates 11 are vertically and parallelly arranged at intervals, and between the two mounting vertical plates 11, a mounting horizontal plate 12 is fixedly connected to the two mounting vertical plates 11 through a connecting piece, and the mounting horizontal plate 12 is perpendicular to the two mounting vertical plates 11.

[0025] The top surface of the installation horizontal plate 12 is fixedly connected to a variable pitch drive component installation portion 5, and the variable pitch drive component installation portion 5 is fixedly connected to the top surface of the output end of a variable pitch drive component (not shown in the figure). The back of the installation horizontal plate 12 is fixedly provided with a change-type drive component 3 arranged along the X-axis in the driving direction, and the output end of the change-type drive component 3 is arranged along the X-axis toward the above-mentioned clamping claw docking assembly. The variable pitch drive component synchronously drives the installation vertical plate 11, the installation horizontal plate 12 and the change-type drive component 3 to move up, down, left and right through its output end.

[0026] The two vertical sides of the two mounting vertical plates 11 located in the same plane are fixed with a clamping claw docking assembly. In this embodiment, the clamping claw docking assembly includes a clamping claw docking plate 21 and two first clamping claw fixing parts. The two parallel vertical sides on the back of the clamping claw docking plate 21 are respectively fixed with the two vertical sides of the two mounting vertical plates 11 located in the same plane, and the clamping claw docking plate 21 is provided with a docking through hole 211, and the above-mentioned mounting cross plate 12 is located above the docking through hole 211. The two first clamping claw fixing parts are fixed on the surface of the clamping claw docking plate 21 in parallel and at intervals along the vertical direction, and the docking through hole 211 is located between the two first clamping claw fixing parts. The clamping claw assembly is engaged with the position between the above-mentioned two first clamping claw fixing parts, so the position between the above-mentioned two first clamping claw fixing parts is adapted to the size of the clamping claw assembly fixed end. The output end of the above-mentioned change-type drive component 3 can extend along the X-axis direction and pass through the docking through hole 211, or withdraw from the docking through hole 211 along the X-axis direction.

[0027] In this embodiment, each first clamp fixing portion includes an upper pressing block 221 and a trapezoidal lower pressing block 222. The surface where the upper pressing block 221 contacts the trapezoidal lower pressing block 222 is defined as the inner surface, and the surface where the upper pressing block 221 is away from the trapezoidal lower pressing block 222 is defined as the outer surface. The upper pressing block 221 is a rectangular block, and the inner surface of the upper pressing block 221 is provided with a rectangular boss 2211 and a slide 2212, and the slide 2212 is a rectangle concave from the inner surface of the upper pressing block toward the outer surface of the upper pressing block. The trapezoidal lower pressing block 222 is a right-angled trapezoidal block, and the upper base of the trapezoidal pressing block is equal to the longitudinal width of the boss 2211, the lower base width of the trapezoidal lower pressing block 222 is not greater than the longitudinal width of the upper pressing block 221, and the vertical length of the upper pressing block 221 is equal to the height of the trapezoidal lower pressing block 222. When in use, the trapezoidal lower pressing block 222 of the first clamping jaw fixing part is in an inverted trapezoidal shape and the hypotenuse of the trapezoidal lower pressing block 222 faces the clamping jaw assembly and is fixed on the clamping jaw docking plate 21. The boss 2211 of the upper pressing block 222 is fixed on the surface of the trapezoidal lower pressing block 222, and one side of the boss 2211 is aligned with the right-angled side of the trapezoidal lower pressing block 222, thereby forming a cavity between the slideway 2212 and the corresponding surface of the clamping jaw docking plate 21. After the above two first clamping jaw fixing parts are fixed on the clamping jaw docking plate 21, an isosceles trapezoidal surface is formed between the two first clamping jaw fixing parts and the clamping jaw docking plate 21.

[0028] A clamp assembly is clamped between the two first clamp fixing parts. In this embodiment, the clamp assembly includes a clamp 41 and a clamp back plate 42. In this embodiment, the clamp is a common standard clamp in the prior art, model ES24-500, and the specific shape is not repeated here. The clamp here can also be other clamps suitable for battery module boxing. The clamp back plate 42 includes a back plate clamping part 421 and a back plate docking platform 422, and the longitudinal width of the back plate clamping part 421 and the back plate docking platform 422 are the same, and the back plate clamping part 421 is in the shape of an isosceles trapezoid, and the size is suitable for the size of the isosceles trapezoidal surface between the two first clamp fixing parts on the clamp docking plate 21. The back plate clamping part 421 is also provided with a clamping groove 43 that is recessed from the back of the clamp back plate 42 to the surface of the clamp back plate 42. The clamp 41 is detachably fixed on the surface of the back plate docking platform 422 through a connector. The two side edges of the upper end of the back panel clamping part 421 can slide into the cavity formed by the slideways 2212 of the two first clamping claw fixing parts and the clamp docking plate 21, and the two vertical side edges of the back panel clamping part 421 are just pressed under each corresponding slideway 2212. After the back panel clamping part 421 is clamped in place, the top surface of the back panel docking platform 422 abuts against the bottom surfaces of the two first clamping claw fixing parts, and the clamping groove 43 is colinear with the central axis of the docking through hole 211.

[0029] The output end of the above-mentioned shape-changing driving component 3 can pass through the docking through hole 211 along the X-axis direction and then be slidably connected to the clamping groove 43. In addition, a docking block 31 is fixedly provided at the top of the output end of the above-mentioned shape-changing driving component 3. When the docking block 31 passes through the docking through hole 211 along the X-axis with the output end of the shape-changing driving component 3, it then slides into the clamping groove 43, and at this time, the clamping claw back plate 42 and the clamping claw 41 are fixed on the clamping claw docking assembly.

[0030] In addition, a second clamp fixing portion is provided on the clamp docking plate 21 in the vertical direction between the two first clamp fixing portions. In this embodiment, the second clamp fixing portion includes a T-shaped base 231, a bolt 232, and a nut 233. The T-shaped base 231 is a T-shaped block and has a threaded hole at its lower end. The lower end of the bolt 232 passes through the threaded hole and then sleeves the nut 233. The upper end of the T-shaped base 231 is fixed on the top surface of the clamp docking plate 21, and the lower end thereof is perpendicular to the clamp docking plate 21 and the bottom surface of the bolt 232 is located above the upper surface of the engaging groove 43. When the docking block 31 slides into the engaging groove 43 along with the output end of the change-type driving component 3, the length of the bolt 232 is adjusted so that the bottom end of the bolt 232 is just in contact with the top surface of the upper surface of the engaging groove 43, and then the nut 233 is tightened to tighten the bolt 232, thereby applying a vertical downward pressure to the clamping jaw assembly, thereby strengthening the connection between the clamping jaw back plate 42 and the clamping jaw docking plate 21 and the docking block 31.

[0031] The working principle and working process of the utility model are as follows: the clamping jaw assembly to be changed is placed on the clamping jaw quick-change platform, and then the pitch-changing driving component is started, and the mounting plate, the changing driving component 3 on the mounting plate and the clamping jaw docking component are synchronously moved to the upper position of the clamping jaw assembly on the clamping jaw quick-change platform (wherein the clamping jaw back plate 42 of the clamping jaw assembly faces upward and the clamping jaw 41 is placed downward), and at this time, the pitch-changing driving component is operated to descend, thereby synchronously driving the mounting plate, the changing driving component 3 on the mounting plate and the clamping jaw docking component to synchronously descend until the clamping jaws in the clamping jaw docking assembly are The bottom ends of the two first clamping jaw fixing parts on the docking plate 21 abut against the top end of the clamping jaw back plate 42. At this time, the clamping jaw docking plate 21 continues to descend, and the clamping jaw engaging part 421 on the clamping jaw back plate 42 slides into the position between the two first clamping jaw fixing parts. At the same time, the variable pitch drive component is turned off, and the type-changing drive component 3 is started, so that the output end of the type-changing drive component 3 synchronously drives the docking block 31 to move into the engaging groove 43. At this time, the bottom end of the bolt 232 of the second clamping jaw fixing part just abuts against the upper surface of the engaging groove 43, thereby completing the fixation of the clamping jaw assembly. When the above-mentioned jaw assembly needs to be replaced, the mold-changing drive component 3 is started, so that the output end of the mold-changing drive component 3 synchronously drives the docking block 31 to retract from the engaging groove 43 along the X-axis direction until the docking block 31 retracts to the back of the docking through hole 211. At this time, there is no connection between the above-mentioned jaw assembly and the jaw docking plate 21, and then the mold-changing drive component 3 is shut down, and the variable pitch drive component is started, and the mounting plate, the mold-changing drive component on the mounting plate and the jaw docking plate 21 are synchronously moved to the location where the jaw assembly is needed, and the cycle is carried out to quickly and efficiently complete the jaw mold change.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
