It eliminates the need to set a driving mechanism on the transfer fixture, reducing equipment costs, simplifying the layout of the transfer fixture, reducing the difficulty of the layout of the transfer fixture, and helping to reduce the size and weight of the transfer fixture, thereby reducing the difficulty and cost of transfer.

[0020] At the same time, since the drive mechanism is omitted from the transfer fixture, the height or height space of the transfer fixture is not increased due to the drive mechanism.

[0033] The following description, in conjunction with the accompanying drawings, describes the transfer fixture transmission structure, the snap-fit ​​battery cell housing device, and the assembly welding line according to embodiments of the present invention.

[0034] Reference Figures 1 to 5 The present invention aims to provide an embodiment of a transfer fixture transmission structure, which may be part of a snap-fit ​​battery cell housing device. Therefore, the present invention also aims to provide an embodiment of a snap-fit ​​battery cell housing device, which includes a transfer fixture transmission structure.

[0035] Meanwhile, the snap-fit ​​cell insertion device can be part of the cell assembly and welding line. Therefore, this utility model also aims to provide an embodiment of the cell assembly and welding line.

[0036] Reference Figure 1 The present invention provides a battery cell assembly and welding line comprising a return line 230, multiple battery cell housing fixtures disposed on the return line 230, and various processing devices and testing devices arranged along the return line 230. The processing devices include processing devices and assembly devices. The processing devices can perform physical processing such as cutting, welding and bending on the semi-finished battery cells, while the assembly devices can perform operations such as installation and assembly on the semi-finished battery cells, assembling two or more components together.

[0037] The specific structure of various processing and testing devices can be determined according to the specific settings of the battery cell manufacturing process. Since this is not the focus of this application, it will not be described in detail here.

[0038] Since the battery cell housing fixture circulates on the return line 230, the battery cell housing fixture is a type of transfer fixture 100. In the following text, transfer fixture 100 refers to the battery cell housing fixture, but is not limited to the battery cell housing fixture.

[0039] Due to the needs of battery cell manufacturing, the battery cell insertion fixture will have a first semi-finished product and a second semi-finished product. The first semi-finished product and the second semi-finished product need to be processed separately. Then, the insertion operation is carried out, that is, the battery cell needs to be flipped so that the battery cell is installed into the corresponding housing.

[0040] Therefore, referring to Figure 2 The cell housing fixture, also known as the transfer fixture 100, includes a base 110. The base 110 is connected to the return line 230 to meet the transfer needs of the transfer fixture 100. At the same time, the base 110 is provided with a first tooling 120 and a second tooling 130. The first tooling 120 is used to set the first semi-finished product, and the second tooling 130 is used to set the second semi-finished product.

[0041] The second tooling 130 has a first state and a second state. In the first state, the first semi-finished product and the second semi-finished product are separated from each other, and can be processed and assembled separately. In the second state, the first semi-finished product and the second semi-finished product are brought close together so that they can be connected or assembled.

[0042] In this embodiment, the second tooling 130 approaches the first tooling 120 in a flipping manner to complete the battery cell insertion. For other products besides the battery cell, the second tooling 130 can approach the first tooling 120 by horizontal rotation, horizontal movement, tilting movement, etc., to meet the actual manufacturing needs of specific products.

[0043] To drive the second tooling 130 to rotate, a motor can be installed on the transfer fixture 100. The motor drives the second tooling 130 to rotate, so as to accurately complete the connection or assembly of the first semi-finished product and the second semi-finished product.

[0044] However, installing motors on the transfer fixture 100 has several drawbacks. First, the large number of transfer fixtures 100 will significantly increase equipment costs. Second, the space required to install motors on the transfer fixture 100 will increase the size, volume, and weight of the transfer fixture 100, and also increase the energy consumption of the transfer fixture 100 during operation.

[0045] In addition, because the cell welding and assembly line requires a series of processes, the motor will block the processing or assembly route of the first or second semi-finished product, making cell production difficult or inefficient.

[0046] In response, this utility model proposes a transmission structure for a transfer fixture, which can eliminate the power component on the transfer fixture 100, reduce equipment costs, simplify the layout of the transfer fixture 100, reduce the difficulty of arranging the transfer fixture 100, and help to reduce the volume and weight of the transfer fixture 100, thereby reducing the difficulty and cost of transfer.

[0047] The transfer fixture transmission structure also includes a drive mechanism 140, which has a first position and a second position. In the first position, the drive mechanism 140 is separated from the transfer fixture 100. In the second position, the drive mechanism 140 is connected to the second tooling 130. The drive mechanism 140 can drive the second tooling 130 to move so that the second tooling 130 switches from the first state to the second state.

[0048] In an embodiment of the snap-fit ​​battery cell insertion device, the drive mechanism 140 completes the insertion of the battery cell by driving the second tooling 130 to rotate. Therefore, the drive mechanism 140 can refer to the rotation drive mechanism of the snap-fit ​​battery cell insertion device.

[0049] In an embodiment of the snap-fit ​​battery cell housing device, the flipping drive mechanism, that is, the drive mechanism 140, completes the switching between the first position and the second position by lifting and lowering. Specifically, in the first position, the drive mechanism 140 is located above the transfer fixture 100, and the drive mechanism 140 can be lowered to switch from the first position to the second position.

[0050] In an embodiment of the snap-fit ​​battery cell housing device, the drive mechanism 140 is raised and lowered by an electric cylinder. Alternatively, the drive mechanism 140 can also be raised and lowered by means of gear rack, ball screw, screw sleeve, pneumatic cylinder, hydraulic cylinder, etc.

[0051] For products other than battery cells, the specific form of switching from the first position to the second position can be achieved by the drive mechanism 140 using various position switching methods, such as rising, vertical lifting, a combination of lifting and translation, or a combination of lifting, translation, and rotation, to meet the needs of cooperating with the second tooling 130.

[0052] In order to drive the second tooling 130 to rotate, in some specific embodiments of this utility model, the drive mechanism 140 may include a drive shaft 150, the second tooling 130 may include a transmission shaft 160, and the end of the drive shaft 150 may be engaged with the end of the transmission shaft 160 to drive the transmission shaft 160 to rotate.

[0053] Since the end of the drive shaft 150 is engaged with the end of the transmission shaft 160, the power of the drive shaft 150 can be transmitted to the transmission shaft 160, thereby driving the second tooling 130 to rotate.

[0054] In this embodiment, by setting a drive mechanism 140, the drive mechanism 140 has a first position and a second position. Therefore, when the drive mechanism 140 switches from the first position to the second position, the drive mechanism 140 can be connected to the second tooling 130 for transmission, so that the drive mechanism 140 can drive the second tooling 130 to move, so that a part of the transfer fixture 100 can move to complete the set action. It is not necessary to set the drive mechanism 140 on the transfer fixture 100, which reduces equipment costs, simplifies the layout of the transfer fixture 100, reduces the difficulty of the layout of the transfer fixture 100, and helps to reduce the size and weight of the transfer fixture 100, and reduce the difficulty and cost of transfer.

[0055] Meanwhile, since the drive mechanism 140 is omitted from the transfer fixture 100, the height or height space of the transfer fixture 100 is not increased due to the drive mechanism 140. This reduces the obstruction of products or tooling and avoids affecting the setting of product processing and assembly routes due to the setting of the drive mechanism 140, thus facilitating product processing and assembly.

[0056] Meanwhile, all transfer fixtures 100 can pass through the drive mechanism 140, and the moving parts of the transfer fixtures 100 can complete the set actions under the drive of the drive mechanism 140 without affecting the processing and assembly of the product.

[0057] Meanwhile, the moving parts of the drive mechanism 140 drive the transfer fixture 100 to perform their actions during the production cycle of the assembly line or return line 230, making full use of the pauses in the assembly line or return line 230 and not affecting production efficiency.

[0058] Regarding the power supply for connecting the drive shaft 150, refer to... Figure 5 The motor can be connected to the pulley via a synchronous belt, and the pulley can be connected to the drive shaft 150 via a coupling, thereby driving the drive shaft 150. At the same time, it also allows the motor to be located above the drive shaft 150, avoiding the motor occupying the space in the axial direction of the drive shaft 150. In particular, it reduces the space occupied by the transfer fixture 100 in the horizontal direction, eliminating the need to increase or extend the return line 230. This makes the cell welding and assembly line structure compact, space-saving, and low in manufacturing cost.

[0059] For the specific cooperation form of the drive shaft 150 and the transmission shaft 160, one of the ends of the drive shaft 150 and the transmission shaft 160 can be provided with a locking block 180, and the other end of the drive shaft 150 and the transmission shaft 160 can be provided with a bayonet 170 for accommodating the locking block 180. The inner surface of the bayonet 170 can match the outer surface of the locking block 180 for transmission.

[0060] In some specific embodiments of this utility model, the bayonet 170 can be a hole with a transmission groove on its inner surface, and the locking block 180 can be a key on the radial outer surface of the rotating shaft. The transmission connection is achieved through the keyway.

[0061] In some specific embodiments of this utility model, the bayonet 170 can be a non-circular hole, and the card block 180 fits against the inner surface of the bayonet 170. When the card block 180 is inserted into the bayonet 170, the drive shaft 150 can drive the transmission shaft 160 to rotate.

[0062] However, the above-described form of the card block 180 and the bayonet 170 requires an increase in the displacement of the drive mechanism 140 along the axial direction of the drive shaft 150, which makes the specific structure of the drive mechanism 140 switching from the first position to the second position complex and increases manufacturing costs.

[0063] In some specific embodiments of this utility model, the bayonet 170 may have a radial opening 220, which is located in the radial direction of the rotating shaft. The radial opening 220 allows the bayonet block 180 and the bayonet 170 to approach and separate along the radial direction of the rotating shaft, so that the drive mechanism 140 switches between a first position and a second position.

[0064] Therefore, the drive mechanism 140 descends directly, and the block 180 enters the bayonet 170 from the radial opening 220, without the drive mechanism 140 generating displacement along the axial direction of the drive shaft 150.

[0065] In an embodiment of the snap-fit ​​battery cell housing device, the drive shaft 150 is provided with a bayonet 170, while the transmission shaft 160 is provided with a locking block 180, which helps to reduce manufacturing difficulty.

[0066] In an embodiment of the snap-fit ​​battery cell housing device, the drive shaft 160 includes a shaft body 190, and the second tooling 130 includes a rotating seat 200. The rotating seat 200 is used to set the second semi-finished product. The rotating seat 200 includes a mounting part 210. The mounting part 210 is provided with a mounting hole for accommodating the shaft body 190. The mounting part 210 is used to form a locking block 180 or a locking slot 170.

[0067] It is easy to understand that by using the mounting portion 210 of the rotating seat 200 to form the locking block 180 or the locking slot 170, this embodiment also reduces the processing of the transmission shaft 160 and reduces manufacturing costs. That is, it is equivalent to shortening the transmission shaft 160 and forming the locking block 180 by the portion surrounding the shaft body 190, so as to simplify manufacturing.

[0068] In this embodiment, Figure 2 In the diagram, the left-side pivot 190 is not shown; it is instead identified as the right-side pivot 190 for ease of understanding.

[0069] At the same time, the rotating shaft 190 will connect to the first tooling 120 or the base 110 to form the rotation center line of the second tooling 130.

[0070] It should be noted that the transmission shaft 160 in this embodiment is actually a limitation on the function of the component, and is a limitation on a part of the rotating center of the rotating seat 200, rather than a specific single part.

[0071] In an embodiment of the snap-fit ​​battery cell housing device, the axial directions of the drive shaft 150 and the transmission shaft 160 are arranged in the horizontal direction. The second tooling 130 can be rotated around the axial direction of the transmission shaft 160 to switch from the first state to the second state, so as to meet the need for the second tooling 130 to rotate in a flipping manner.

[0072] In the embodiments of the snap-fit ​​battery cell housing device and the battery cell assembly welding line, the transfer fixture 100 has a transfer conveying direction, and in the second position, the drive mechanism 140 is located on the incoming side or the outgoing side of the transfer fixture 100 along the transfer conveying direction.

[0073] It is easy to understand that this embodiment also adapts to the arrangement of the second tooling 130 and the first tooling 120 along the left and right directions of the return line 230, which reduces the mutual obstruction between the first tooling 120 and the second tooling 130, facilitates the processing of the first semi-finished product and the second semi-finished product, and does not affect each other.

[0074] In an embodiment of the cell assembly and welding line, in the material feeding direction of the flipping drive mechanism, the return line 230 is provided with a positioning detection mechanism. The positioning detection mechanism can be used to detect and determine whether the second tooling 130 is in the first state, thereby preventing the bayonet 170 from not being fitted onto the outside of the card block 180 when the drive mechanism 140 descends.

[0075] In the embodiment of the cell assembly and welding line, the positioning and detection mechanism can also perform other detections to meet the needs of cell production and manufacturing, such as whether the cell of the second tooling 130 has been processed or positioned, and whether the second tooling 130 has a housing for cell insertion.

[0076] In some specific embodiments of this utility model, the positioning detection mechanism may include a camera, a laser detector, etc., to meet different usage needs.

[0077] In an embodiment of the cell assembly and welding line, a material handling mechanism can be arranged next to the return line 230 to meet the needs of placing semi-finished products and taking out finished products, thereby achieving continuous cycle production.

[0078] In some specific embodiments of this utility model, the material handling mechanism may include a multi-directionally movable suction cup to reduce clamping damage.
