This battery structure is relatively simple, the overall weight is lighter, it has a relatively high energy density, and the safety is relatively high at the same time.

[0003] In the electrolyte injection process of the square aluminum shell battery, it is necessary to weigh before and after injection. During the weighing process, it is required that the square aluminum shell battery does not touch any object. Before and after weighing, in order to adapt to the pick-and-place of the manipulator, it is necessary to fix the battery during injection and pick-and-place. In the prior art, due to the relatively separate weighing position and injection position, it is often necessary to pick and place multiple times before and after injection, so the processing efficiency is low. Therefore, an integrated clamping and weighing mechanism is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: A clamping and weighing integrated mechanism includes a battery 1 and a bracket 2 for supporting the overall device. The battery 1 is a semi-finished product waiting for injection molding. The top of the bracket 2 is fixedly connected with a fixed plate 3 for supporting the weighing component 4 and the clamping component 5. The top of the fixed plate 3 is provided with a linear bearing 6 for supporting the sliding of the slide bar 42. The top of the fixed plate 3 is provided with a weighing component 4 for weighing the battery 1. The weighing component 4 includes a slide bar 42 for connecting the intermediate plate 43 and the driving plate 49. The slide bar 42 penetrates and slides on the inner wall of the linear bearing 6. The slide bar 42 can slide up and down through the linear bearing 6. The bottom end of the slide bar 42 is fixedly connected with a driving plate 49 for supporting the cylinder 41. The top of the fixed plate 3 is provided with a clamping component 5 for fixing the battery 1. The clamping component 5 includes a cam plate 51 for driving the follower 52 to move. The bottom end of the cam plate 51 is fixedly connected to the top of the fixed plate 3.

[0031] Refer to Figure 1 - Figure 3, the weighing component 4 further includes a cylinder 41 for driving the entire device. The bottom end of the cylinder 41 is mounted on the top end of the driving plate 49, and the top end of the output shaft of the cylinder 41 is mounted on the bottom end of the fixing plate 3. By starting the cylinder 41, the driving plate 49 can be driven to move up and down under the support of the fixing plate 3. The top end of the slide bar 42 is fixedly connected to an intermediate plate 43 for supporting the weighing sensor 47. The top end of the intermediate plate 43 is mounted with a weighing sensor 47 for weighing. The top end of the weighing sensor 47 is mounted with a detection head 48 for supporting the battery 1. The detection head 48 is an inherent component of the weighing sensor 47. By using the detection head 48 to lift the battery 1, its weight can be measured. The top end of the intermediate plate 43 is fixedly connected to an equal-height rod 44 for supporting the support plate 45. The top end of the equal-height rod 44 is fixedly connected to a support plate 45 for supporting the cushion plate 46. The detection head 48 penetrates and slides on the bottom end of the support plate 45.

[0032] Referring to Figure 2 - Figure 4 , the clamping component 5 further includes a support seat 53 for supporting the guide rod 54. The left end of the support seat 53 is fixedly connected to a guide rod 54 for guiding the sliding of the sliding seat 55. The outer wall of the guide rod 54 is slidably connected to a sliding seat 55 for driving the sliding of the support rod 56. The sliding seat 55 can slide left and right on the outer wall of the guide rod 54. The front end of the sliding seat 55 is slidably connected to the inner wall of the cam plate 51. When the intermediate plate 43 moves up and down, it will drive the sliding seat 55 and the follower 52 to move up and down through the sliding seat 55 and the guide rod 54. When the follower 52 moves up and down, it will be guided by the cam plate 51 to move inwards or outwards. The rear end of the sliding seat 55 is fixedly connected to a support rod 56 for supporting the clamping plate 57. The top end of the support rod 56 is fixedly connected to a clamping plate 57 for positioning the battery 1. When the support rod 56 moves, it will drive the clamping plate 57 to move synchronously. There are multiple sets of the cam plate 51, the follower 52, the sliding seat 55, the support rod 56, and the clamping plate 57. The multiple sets of the cam plate 51, the follower 52, the sliding seat 55, the support rod 56, and the clamping plate 57 are symmetrically arranged with the center line of the fixing plate 3 as the axis of symmetry. When the intermediate plate 43 moves, the two followers 52 will move synchronously. In this way, the battery 1 can be fixed from both sides at the same time. The top end of the support plate 45 is fixedly connected to a cushion plate 46 for directly supporting the battery 1. The battery 1 is placed on the top end of the cushion plate 46. The cushion plate 46 is made of rubber material and is not easy to conduct electricity. The detection head 48 penetrates and slides on the inner wall of the cushion plate 46.

[0033] Working principle: After the injection molding is completed, the air cylinder 41 can be started to drive the driving plate 49 to move downward. When the driving plate 49 moves downward, it will drive the middle plate 43 to move downward through the sliding rod 42. When the middle plate 43 moves downward, it will drive the support seat 53, the guide rod 54, the sliding seat 55, and the follower 52 to move downward synchronously. When the follower 52 moves downward, it will be guided by the cam plate 51 and move outward. The sliding seat 55 will also move outward under the influence of the follower 52. When the sliding seat 55 moves outward, it will drive the support rod 56 and the clamping plate 57 to move outward. When the clamping plate 57 moves outward, it will disengage from the outer wall of the battery 1.

[0034] While the clamping plate 57 disengages from the outer wall of the battery 1, since the middle plate 43 moves downward, the equal-height rod 44 and the support plate 45 will also move downward synchronously. When the support plate 45 moves downward, the detection head 48 will pass through the support plate 45 and the backing plate 46. In this way, the support plate 45 will directly support the battery 1, and thus the weighing of the battery 1 can be achieved. After the weighing is completed, the air cylinder 41 can be started to move in the reverse direction to drive the clamping plate 57 to fix the battery 1 again, so that it is convenient for the robot to pick and place.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
