Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery core shelling device. Background Art

[0002] As a common source of energy, batteries are widely used in daily life due to their small size and light weight. The battery cells are wrapped in a battery casing. During the battery production process, the battery cells need to be loaded into the battery casing. This step is called the shelling process. The shelling accuracy of the battery cells affects the performance of the battery.

[0003] In the prior art, the shell insertion device is a movable guide member, which uses a slider to drive the battery cell to move into the battery cell shell to achieve assembly between the battery cell and the battery cell shell. If the slider shakes or vibrates during movement, the battery cell may deviate during assembly due to the shaking of the slider, or the slider may become loose due to long-term use, causing the alignment of the battery cell and the battery cell shell to deviate, resulting in the battery cell getting stuck when entering the shell, affecting the battery production efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model uses the guide section and the guide hole to automatically guide the battery cell and the battery cell shell respectively. The specific technical solution is as follows:

[0005] A battery cell shell insertion device comprises a first support member, a guide member and a second support member which are arranged in sequence, wherein the top surfaces of the first support member, the guide member and the second support member are provided with corresponding coaxial guide grooves along a colinear direction, a battery cell shell having one end resting on the guide member is built into the guide groove of the first support member, and the guide groove of the second support member has the same cross-section as that of the guide groove of the guide member and has a battery cell built into it.

[0006] Preferably, a guide portion is provided on a side of the guide member facing the second support member, and a radius of the guide portion gradually increases along the axis of the guide member toward a side of the second support member.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0020] The battery cell shelling device provided in the present application is suitable for assembling batteries that may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-ion batteries or magnesium-ion batteries, etc., which is not limited in the present application. The battery may be cylindrical, flat, rectangular or in other shapes, etc., which is not limited in the embodiments of the present application. The battery cell shelling process is to install the battery cell into the battery cell shell. At present, the automatic shelling method using a movable guide is more commonly used. In this automatic shelling method, the screws that fix the slider under the movable guide part will become loose during use due to structural problems, causing the guide part to move slightly left and right, causing the shell to get stuck, thereby affecting the production efficiency of the battery.

[0021] like Figure 1-Figure 5 As shown, the battery cell shelling device includes a first support member 30, a guide member 40 and a second support member 50 which are arranged in sequence. The top surfaces of the first support member 30, the guide member 40 and the second support member 50 are provided with corresponding coaxial guide grooves along the colinear direction. The guide groove of the first support member 30 is built with a battery cell shell 90 with one end leaning against the guide member 40. The guide groove of the second support member 50 has the same cross-section as the guide groove of the guide member 40 and has a battery cell 100 built therein. The direction of the first support member 30 toward the guide member 40 and the second support member 50 is set to X, the guide groove of the first support member 30 is set to a first guide groove 310, the guide groove of the second support member 50 is set to a second guide groove 510, the guide groove of the guide member 40 is set to a third guide groove 421, and the first guide groove 31 0. The cross-sections of the second guide groove 510 and the third guide groove 421 can be V-shaped, U-shaped or arc-shaped, and their specific shapes can be selected according to the specific shapes of the battery cell 100 and the battery cell shell 90, and are used to support the battery cell 100 or the battery cell shell 90. The first guide groove 310, the second guide groove 510 and the third guide groove 421 are all on the same axis. When the battery cell shell 90 is located in the first guide groove 310, and the end is against the end side of the guide member 40, the battery cell 100 is located in the second guide groove 510. By applying a force along the X direction to the battery cell shell 90, and then applying a reverse force along the X direction to the battery cell 100, the battery cell 100 is gradually moved from the second guide groove 510 to the third guide groove 421 and until it moves into the battery cell shell 90, the battery cell 100 is shelled.

[0022] The bottom ends of the first support member 30, the second support member 50 and the guide member 40 are all fixedly installed with support connecting members 110, which are in the shape of a block, a scissors bracket or a column, and are used to play a supporting role. The bottom ends of the support connecting members 110 are fixed to a base 10 located on the same horizontal plane, and the bottom ends of the base 10 are fixedly installed with a base 20, which plays a supporting role for the first support member 30, the second support member 50 and the guide member 40 through the base 10, the base 20 and the support connecting members 110.

[0023] like Figure 6 As shown, a guide portion 420 is provided on the side of the guide member 40 facing the second support member 50, and the radius of the guide portion 420 gradually increases along the axis of the guide member 40 toward the side of the second support member 50, and preferably, the angle between the side of the guide portion 420 and the X direction is 15°, wherein the third guide groove 421 includes a positioning segment 401 and a guide segment 402 close to the second guide groove 510, the cross-section of the positioning segment 401 is equal to the cross-section of the second guide groove 510, and the radius of the guide segment 402 gradually increases in the direction toward the second guide groove 510, when the battery cell 100 moves from the second guide groove 510 to the guide segment 402, the guide segment 402 guides the end of the battery cell 100, and guides the end of the battery cell 100 to the positioning segment 401 by itself, so as to prevent the second support member 50 from being offset relative to the guide member 40, which affects the movement of the battery cell 100 to the positioning segment 401.

[0024] like Figure 6 and Figure 7 As shown, a step surface 412 that fits with the end of the battery cell housing 90 is provided at one end of the guide member 40 facing the first support member 30, and a guide hole 411 is provided at one end of the step surface 412 facing the first support member 30, wherein the guide member 40 is divided into a guide portion 420 and a clamping portion 410 arranged on the guide portion 420 close to the first support member 30, and the guide hole 411 and the step surface 412 are both arranged on the side of the clamping portion 410 facing the first support member 30. When the battery cell housing 90 on the first support member 30 is positionally offset, if it does not exceed the diameter range of the opening of the guide hole 411, it can still enter the step surface 412 from the opening of the guide hole 411, thereby preventing the battery cell housing 90 from being blocked on the end surface of the clamping portion 410 due to positional offset, and making it easier for the battery cell housing 90 to abut against the step surface 412 along the guide hole 411, thereby limiting the position of the battery cell housing 90.

[0025] like Figure 1 and Figure 6 As shown, the first support member 30 and the second support member 50 are respectively installed with a first push rod 60 and a second push rod 70 at one end away from the guide member 40, wherein the first push rod 60 is used to squeeze one end of the battery cell housing 90 so that the other end of the battery cell housing 90 is close to the step surface 412 to prevent the battery cell housing 90 from shifting, and the piston rod of the second push rod 70 is extended to squeeze the end of the battery cell 100 so that the battery cell 100 is pushed from the second guide groove 510 to the positioning section 401, and is pushed from the positioning section 401 into the battery cell housing 90 to achieve the shell insertion operation; the first push rod 60 and the second push rod 70 can adopt one of a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0026] A clamping jaw 80 is provided at one end of the first support member 30 away from the guide member 40. The clamping jaw 80 is moved by an external device. The clamping jaw 80 clamps one end of the battery cell housing 90 outside the first support member 30. In the present application, the initial state of the clamping jaw 80 is an open state on both sides. The first push rod 60 pushes the battery cell housing 90 to the clamping portion 410 of the guide member 40. At the same time, the second push rod 70 also pushes the battery cell 100 to the third guide groove 421 of the guide member 40. The second push rod 70 pushes the battery cell 100 to continue to push it in the reverse direction of X to the positioning section 401 for shell insertion. After the second push rod 70 pushes the battery cell 100 to the clamping portion 410 of the guide member 40 to enter the shell, it continues to push the battery cell 100 until it is completely shelled and then pushed out to the top of the conveyor line in the reverse direction of X. The second push rod 70 returns to the initial position.

[0027] The battery cell 100 enters the battery cell housing 90 through the guide member 40, and the second push rod 70 pushes the battery cell 100 into the battery cell housing 90. One end of the battery cell 100 exceeds the position of the clamping portion 410 and is located in the middle of the first support member 30. At this time, the battery cell housing 90 is located at the clamping portion 410 and has not yet separated from the clamping portion 410. After the battery cell 100 is shelled, the battery cell housing 90 completely covers the battery cell 100, and the clamping claws 80 clamp the battery cell housing 90, and the battery cell housing 90 and the battery cell 100 are pulled out from the direction of separating from the clamping portion 410. The shelled battery cell 100 is located in the middle of the first support member 30. At this time, the conveying lines on both sides of the first support member 30 lift the shelled battery cell 100 to move to the next process.

[0028] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
