[0049] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] Combine the following Figures 1 to 9 , the battery cell module extrusion device provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0051] like Figure 1 and Figure 2 As shown, this embodiment provides a battery cell module extrusion device 1, including: a frame 11, a lifting assembly 12, a first pressing assembly 13 and a second pressing assembly 14.

[0052] The lifting assembly 12 is installed on the frame 11 in a liftable manner.

[0053] Along the length direction of the battery cell module 21, the first clamping assembly 13 and the second clamping assembly 14 are used to be arranged on opposite sides of the battery cell module 21 on the tooling plate 2 in an opposing manner. The first clamping assembly 13 is fixedly installed on the lifting assembly 12, and the second clamping assembly 14 can be selectively installed on the lifting assembly 12 or the tooling plate 2, and is configured to be movable along the length direction of the battery cell module 21.

[0054] The first pressing assembly 13 is used to stop one end of the battery cell module 21 , and the second pressing assembly 14 is used to press the other end of the battery cell module 21 .

[0055] It is understandable that the frame 11 provides a mounting support for the lifting plate 121. The frame 11 of this embodiment is formed by splicing a plurality of steel sections. The frame 11 of this embodiment is placed on the upper side of the main line body 4 for conveying the battery cells.

[0056] Optionally, the lifting assembly 12 can be arranged above the main line body 4, and the first pressing assembly 13 and the second pressing assembly 14 are arranged at the bottom of the lifting assembly 12 to press the battery cell module 21 from the upper side; the lifting assembly 12 can also be arranged below the main line body 4, and the first pressing assembly 13 and the second pressing assembly 14 are arranged at the top of the lifting assembly 12 to press the battery cell module 21 from the lower side. This embodiment is described by taking the lifting assembly 12 arranged above the main line body 4 as an example.

[0057] When the second clamping assembly 14 is installed on the lifting assembly 12 or the tooling plate 2, the installation direction of the second clamping assembly 14 is relatively flipped 180°.

[0058] When the second clamping assembly 14 is installed on the lower side of the lifting assembly 12, the first clamping assembly 13 and the second clamping assembly 14 can move up and down in the vertical direction with the lifting and lowering of the lifting assembly 12. When the battery cell module 21 is about to enter the lower side of the frame 11, the lifting assembly 12 is controlled to drive the first clamping assembly 13 and the second clamping assembly 14 to rise to avoid interference with the battery cell module 21 on the tooling plate 2 transported by the main line body 4. After the battery cell module 21 is transported from the main line body 4 to the lower side of the lifting assembly 12, the lifting assembly 12 is controlled to drive the first clamping assembly 13 and the second clamping assembly 14 to descend, so that the first clamping assembly 13 and the second clamping assembly 14 are respectively placed on both sides of the battery cell module 21. At this time, the lifting assembly 12 stops descending, the first clamping assembly 13 stops one end of the battery cell module 21, and the second clamping assembly 14 is operated to squeeze the other end of the battery cell module 21.

[0059] When the second clamping assembly 14 is installed on the tooling plate 2, the first clamping assembly 13 can move up and down in the vertical direction with the lifting and lowering of the lifting assembly 12. When the battery cell module 21 is about to enter the lower side of the frame 11, the lifting assembly 12 is controlled to drive the first clamping assembly 13 to rise to avoid interference with the battery cell module 21 on the tooling plate 2 transported by the main line body 4. When the battery cell module 21 is transported from the main line body 4 to the lower side of the lifting assembly 12, the lifting assembly 12 is controlled to drive the first clamping assembly 13 to descend so that the first clamping assembly 13 is placed on one side of the battery cell module 21. At this time, the lifting assembly 12 stops descending, the first clamping assembly 13 stops one end of the battery cell module 21, and the second clamping assembly 14 located on the tooling plate 2 is operated to squeeze the other end of the battery cell module 21.

[0060] Among them, the lifting component 12 can be a lifting component of a screw-nut structure. When the screw rotates, the nut moves up and down along the spiral line of the screw, driving the lifting platform to rise and fall. Alternatively, the lifting component 12 can also be composed of a telescopic rod driven by a cylinder and a lifting platform. The extension and retraction of the telescopic rod drives the lifting and falling of the lifting platform.

[0061] The first clamping assembly 13 has a baffle for stopping the battery module 21. In this embodiment, the area of ​​the baffle is larger than the contact surface of the battery module 21, so that the battery module 21 completely contacts the baffle.

[0062] Furthermore, the second clamping assembly 14 may be a clamping structure composed of a gear and a rack, and the compression is achieved based on the relative movement of the gear and the rack, or the second clamping assembly 14 may be a telescopic rod mechanism, and the compression is achieved based on the extension and retraction of the telescopic rod.

[0063] The battery cells are stacked on the tooling plate 2 to form a battery cell module 21, and the battery cell module 21 placed on the tooling plate 2 is transported to the main line body 4 by the transfer trolley 3. The tooling plate 2 is transported to the bottom of the lifting assembly 12 with the battery cell module 21, and the lifting assembly 12 drives the first clamping assembly 13 and the second clamping assembly 14 to be arranged on both sides of the battery cell module 21. Alternatively, the lifting assembly 12 drives the first clamping assembly 13 to be arranged on one side of the battery cell module 21, and the second clamping assembly 14 is installed on the tooling plate 2, and the first clamping assembly 13 stops one side of the battery cell module 21, and the second clamping assembly 14 stops the battery cell module 21. The other side of the group 21 is pressed tightly. Compared with each set of tooling plates 2, which needs to have its own extrusion assembly, a large number of tooling plates 2 are equipped with extrusion assemblies, which increases the cost of the equipment. In this embodiment, the battery cell modules 21 on the numerous tooling plates 2 share a set of extrusion devices 1. The second clamping assembly in the extrusion device 1 can be installed on the lifting assembly or on the tooling plate 2, which saves costs. In addition, the frame 11 can be directly set on the upper side of the main line body 4, and the tooling plate 2 can directly perform the extrusion operation in the path of transportation on the main line body 4 without setting a branch line body, thereby reducing the energy consumption of the equipment.

[0064] The battery cell module extrusion device 1 provided by the utility model is characterized in that a lifting component 12 is arranging on a frame 11 in a liftable manner, and a first clamping component 13 is fixedly arranged on the lifting component 12, and a second clamping component 14 can be selectively installed on the lifting component 12 or the tooling plate 2, so that the first clamping component 13 and the second clamping component 14 are arranged on opposite sides of the battery cell module 21 on the tooling plate 2 in an opposed manner, so that the first clamping component 13 clamps one end of the battery cell component, and the second clamping component 14 squeezes the other end of the battery cell component. The whole set of extrusion device 1 has a simple structure and is easy to operate. The battery cell modules 21 transported on the main line body 4 can be extruded in sequence. Since the first clamping component 13 is arranged on the lifting component 12, the second clamping component 14 can be flipped in the vertical direction, and can be arranged on the lifting component 12 or on the tooling plate 2. The tooling plate 2 only carries the battery cell components, and the second clamping component is selectively installed, which simplifies the structure of the tooling plate 2. The first clamping component 13 and the second clamping component 14 can perform extrusion operations on multiple battery cell modules 21, thereby improving the utilization rate of the extrusion device 1 and reducing the energy consumption and cost during the extrusion process of the battery cell modules 21.

[0065] In some embodiments, Figure 1 and Figure 2 As shown, the lifting assembly 12 of this embodiment includes a lifting plate 121 and a balancer 122. The lifting plate 121 is escalably mounted on the frame 11, and the balancer 122 is disposed on the frame 11 and connected to the lifting plate 121.

[0066] The balancer 122 can be used to balance the weight of the lifting plate 121, so that the lifting plate 121 is in an upward state, ensuring that the lifting plate 121 is suspended on the frame 11 in a balanced manner. The lifting plate 121 of this embodiment is provided with a handle 125, and the operator can pull the handle 125 to make the lifting plate 121 drop. The balancer 122 ensures that the lifting plate 121 will not slide relative to the frame 11 regardless of whether the operator pulls the handle 125 or releases the handle 125. In this way, the coordinated use of the balancer 122 and the handle 125 realizes the lifting and lowering action of the lifting plate 121 relative to the frame 11, and ensures the stability and safety of the lifting and lowering of the lifting plate 121. The balancer 122 is small in size and easy to operate, which can improve the lifting efficiency of the lifting plate 121 and improve the comfort of the lifting and lowering operation of the lifting plate 121.

[0067] Optionally, the balancer 122 may be one of a spring balancer, a pneumatic balancer, and an electric balancer.

[0068] This embodiment uses a spring balancer to balance the weight of the lifting plate 121 through the elastic force of the spring. Based on the characteristics of the spring to quickly adjust and maintain a balanced state, the spring balancer can provide higher balancing accuracy, high stability, and can work stably for a long time, which is beneficial to improving the stability of the lifting action of the lifting plate 121.

[0069] In some embodiments, Figure 4 and Figure 5 As shown, the frame 11 of this embodiment further includes a first limiting member 111 .

[0070] The first position-limiting member 111 is disposed on the frame 11 , and a clamping plate 123 is disposed on one side of the lifting plate 121 close to the frame 11 .

[0071] The first limiting member 111 can be switched between a first state of being extended and a second state of being retracted.

[0072] When the first position-limiting member 111 is in the first state, the first position-limiting member 111 extends out to stop the clamping plate 123 , and when the first position-limiting member 111 is in the second state, the first position-limiting member 111 retracts from the clamping plate 123 .

[0073] It is understandable that along the conveying direction of the main line body 4, a support platform 113 is provided on one side of the frame 11, the first limit member 111 is installed on the support platform 113, and a clamping plate 123 is installed on one side of the lifting plate 121 arranged opposite to the support platform 113. The clamping plate 123 is an L-shaped plate, and the vertical plate of the L-shaped plate is installed on the lifting plate 121 through fasteners, and the horizontal plate of the L-shaped plate extends toward the support platform 113.

[0074] The lifting plate 121 rises under the elastic force of the balancer 122. When the first limit member 111 is in the first state, the first limit member 111 extends out to cover the clamping plate 123, and the frame 11 stops the lifting plate 121 in the height direction, so that the lifting plate 121 cannot rise relative to the frame 11, and then stabilizes at the height of the first limit member 111, which is convenient for the subsequent extrusion operation of the battery cell module 21; when the first limit member 111 is in the second state, the first limit member 111 retracts from the clamping plate 123 to release the clamping plate 123, there is no connection between the lifting plate 121 and the frame 11, the lifting plate 121 can rise relative to the frame 11, and the lifting plate 121 rises to the initial position on the frame 11, which is convenient for the transportation of the tooling plate 2 on the main line body 4 to prevent the first clamping assembly 13 and the second clamping assembly 14 from interfering with the battery cell module 21 in the transportation state.

[0075] Among them, the first limiting member 111 can be a telescopic rod, and the stopping and releasing of the clamping plate 123 is achieved based on the extension and retraction of the telescopic rod relative to the support platform 113. The first limiting member 111 can also be a structure of a slide rail slider, and the stopping and releasing of the clamping plate 123 is achieved based on the forward and backward movement of the slider relative to the slide rail.

[0076] Furthermore, the height of the first limit member 111 relative to the frame 11 can be adjusted, and the support platform 113 is connected to the frame 11 through a horizontally arranged steel section, and both ends of the steel section are installed on the frame 11 through fasteners. For battery cell modules 21 of different heights, the height of the lifting plate 121 can be limited by adjusting the installation position of the steel section, thereby adjusting the height of the first clamping assembly 13 and the second clamping assembly 14 relative to the battery cell module 21, thereby improving the adaptability of the extrusion device 1 to different battery cell modules 21.

[0077] In some embodiments, Figure 4 and Figure 5 As shown, the first limiting member 111 of this embodiment is a limiting indexing pin.

[0078] It can be understood that by rotating the rotating part of the limit indexing pin, the extension and retraction of the pin relative to the clamping plate 123 are controlled to achieve the stopping and releasing of the lifting plate 121. Since the rotating part of the limit indexing pin rotates at a certain interval or indexing, the extension and retraction amount of the pin can be accurately controlled, thereby improving the stability and reliability of the stopping of the lifting plate 121.

[0079] In some embodiments, Figure 1 and Figure 5 As shown, the lifting assembly 12 of this embodiment further includes a second limiting member 124 .

[0080] The second stopper 124 is disposed at the lower side of the lifting plate 121 , and is used to prevent the lifting plate 121 from colliding with the battery cell module 21 when the lifting plate 121 is descending.

[0081] It is understandable that when the operator pulls the handle 125 to drive the lifting plate 121 to descend, the speed is too fast and the lower side of the lifting plate 121 will collide with the battery cell module 21. The second limit plate is made of a flexible plate. When the lifting plate 121 collides with the battery cell module 21, the flexible contact between the second limit plate and the battery cell module 21 may alleviate the impact force and avoid damage to the battery cell module 21.

[0082] Optionally, the second limiting member 124 may be made of a rubber member or a silicone member.

[0083] In some embodiments, Figure 1 and Figure 6 As shown, the frame 11 of this embodiment is provided with a guide rail 112 .

[0084] The guide rail 112 is extended along the lifting direction of the lifting assembly 12 , and the lifting plate 121 is lifted and lowered on the guide rail 112 .

[0085] It can be understood that the outer walls of the two ends of the lifting plate 121 of this embodiment are provided with sliders, which are adapted to the guide rails 112. When the lifting plate 121 is lifted or lowered relative to the frame 11, the sliders can move along the guide of the guide rails 112. The guide rails 112 limit the path of the lifting and lowering movement of the lifting plate 121, thereby avoiding tilting and displacement of the lifting plate 121 during lifting or lowering, and ensuring the stability of the lifting plate 121 during lifting or lowering.

[0086] In some embodiments, Figure 1 and Figure 3 As shown, the second pressing assembly 14 of this embodiment includes a mounting seat 141 , a pressing plate 144 and a driving member 143 , and optionally also includes a pressing head 142 .

[0087] The mounting seat 141 is disposed on the frame 11 and can be turned over in the vertical direction. The driving member 143 is mounted on the mounting seat 141 , and the driving member 143 is drivingly connected to the pressing plate 144 .

[0088] The mounting seat 141 has a first state and a second state:

[0089] Among them, when the mounting seat 141 is in the first state, the clamping plate 144 is movably arranged on the mounting seat 141 along the length direction of the battery cell module 21, and the clamping head 142 is connected to the end of the clamping plate 144 away from the driving member 143, and can avoid the push plate 22 of the tooling plate 2, and the clamping head 142 is configured to squeeze the battery cell module 21.

[0090] When the mounting seat 141 flips 180° from the first state to the second state, the mounting seat 141 can be disposed on the connecting tooling plate 2 , and the pressing plate 144 is configured to press the battery cell module 21 .

[0091] It is understandable that when the mounting base 141 is in the first state, the mounting base 141 is installed on the lower side of the lifting plate 121. At this time, a clamping head 142 is also installed on the side of the clamping plate 144 away from the driving member 143, and a push plate 22 is installed on the tooling plate 2. When the second clamping assembly 14 squeezes one side of the battery cell module 21, the clamping head 142 can avoid the push plate 22 and squeeze the battery cell module 21.

[0092] The top of the mounting seat 141 of the present embodiment is provided with a plurality of circular holes, and the area corresponding to the mounting seat 141 on the lifting plate 121 is provided with a plurality of strip holes. The mounting seat 141 is installed on the lifting plate 121 by fasteners. First, the position of the strip hole to be installed is preliminarily determined according to the length of the battery cell module 21, and the mounting seat 141 is preliminarily connected to the lifting plate 121. Then, based on the relative positions of the strip hole and the circular hole, the position of the mounting seat 141 in the length direction of the battery cell is accurately adjusted so that the distance between the clamping head 142 and one end of the battery cell module 21 reaches a preset spacing.

[0093] After the second pressing assembly 14 is installed in place on the lifting plate 121 , the driving member 143 drives the pressing head 142 to press the battery module 21 along the length direction of the battery module 21 , so that the length of the battery module 21 reaches a preset value.

[0094] The driving member 143 may be manually controlled, pneumatically controlled or electrically controlled, and the driving member 143 may be any one of an electric push rod, a linear motor and a cylinder.

[0095] When the mounting base 141 is in the second state, the mounting base 141 is flipped 180° compared to the first state and installed on the tooling plate 2. At this time, the second clamping assembly 14 does not need to be installed with the clamping head 142, and the push plate 22 does not need to be installed on the tooling plate 2. One side of the battery cell module 21 is directly squeezed through the clamping plate 144.

[0096] In this embodiment, a mounting seat 141, a clamping plate 144 and a driving member 143 are provided in the second press assembly, and a clamping head 142 is optionally installed, so that the clamping head 142 or the clamping plate 144 can extrude the battery cell module 21 under linear drive by the driving member 143. The structure is compact, occupies little space and is easy to implement.

[0097] In some embodiments, Figure 3 As shown, the driving member 143 of this embodiment includes a screw transmission mechanism 1431 and a hand wheel 1432 .

[0098] The screw transmission mechanism 1431 is disposed on the mounting seat 141 , the hand wheel 1432 is connected to the screw of the screw transmission mechanism 1431 , and the screw nut of the screw transmission mechanism 1431 is connected to the clamping plate 144 .

[0099] It is understandable that the screw transmission mechanism 1431 is used to convert the rotational motion of the handwheel 1432 into the linear motion of the clamping plate 144. When the handwheel 1432 is used to rotate the screw, the screw nut moves linearly along the thread of the screw, thereby realizing the linear motion of the screw nut, and then pushing the clamping plate 144 to make linear motion.

[0100] In this embodiment, by setting up a screw transmission mechanism 1431 and a handwheel 1432, the battery cell module 21 can be extruded only by manual means. The extrusion method is simple, does not consume other energy, saves energy and is easy to operate. In addition, the screw transmission mechanism 1431 combined with the handwheel 1432 can achieve precise linear motion or position adjustment through manual operation.

[0101] In some embodiments, Figure 7 and Figure 8 As shown, the pressing head 142 of this embodiment has a relief opening 1421 on one side facing the battery module 21 .

[0102] The avoidance opening 1421 is used to avoid the push plate 22 of the tooling plate 2 when the pressing head 142 squeezes the battery cell module 21 .

[0103] It can be understood that a push plate 22 is provided on the tooling plate 2 of the present embodiment. Four push plates 22 are sequentially arranged on the outer side of the side wall of the battery cell module 21 along the side wall of the battery cell module 21. The push plate 22 located at the front side of the battery cell module 21 along the conveying direction of the battery cell module 21, and the push plate 22 perpendicular to the front side and located on the inner side of the battery cell module 21 are fixedly arranged on the tooling plate 2, and the remaining push plates 22 on both sides are movably arranged on the tooling plate 2. The movably arranged push plate 22 is transmission-connected with a handle 23 arranged on the tooling plate 2. Rotating the handle 23 can drive the push plate 22 to move on the tooling plate 2. By adjusting the spacing between the push plates 22 on both sides of the battery cell module 21, the push plates 22 can clamp and fix the battery cell module 21 in the length and width directions, so that the battery cell module 21 is compressed in both the length and width directions.

[0104] As for the compression in the length direction of the battery cell module 21, since the longer length requires a larger compression force, it is necessary to use the first clamping assembly 13 and the second clamping assembly 14 to cooperate to complete the pressure in the length direction, so that the gap between the single battery cells in the length direction is reduced, and then the handle 23 is rotated to drive the push plate 22 to compress one end of the battery cell module 21. During the stroke of the second clamping assembly 14 pushing toward the battery cell module 21, the push plate 22 will block the path of the second clamping assembly 14. Therefore, the clamping head 142 of this embodiment has an avoidance opening 1421 on the side facing the battery cell module 21. The avoidance opening 1421 can avoid the push plate 22 from abutting against one end of the battery cell module 21, so that the clamping head 142 is not affected by the push plate 22, and can smoothly abut against one end of the battery cell module 21 and compress the battery cell module 21.

[0105] In this embodiment, the push plate 22 is in a rectangular parallelepiped structure and has a rectangular surface opposite to the pressing head 142. The pressing head 142 includes a pressing mounting portion and a pressing contact portion, and the pressing mounting portion is connected.

[0106] In some embodiments, Figure 3 , Figure 8 and Fig. 9 As shown, the pressing plate 144 of this embodiment is configured with an indicator bar 1422 .

[0107] The indicator strip 1422 is located on the adjacent side facing the battery cell module 21 . A pointed tip 14221 is provided at the end of the indicator strip 1422 . The pointed tip 14221 is arranged parallel to the tooling plate 2 .

[0108] The indicator bar 1422 is used to indicate the compression amount of the second clamping assembly 14 along the length direction of the battery cell module 21 .

[0109] It can be understood that a scale 24 is provided on the tooling plate 2 of the present embodiment, and the direction of the scale 24 is set along the length direction of the battery cell module 21. As the clamping plate 144 moves in the length direction of the battery cell, the position of the indicator bar 1422 relative to the scale 24 changes. The changed numerical value, i.e., the clamping amount, can indicate the displacement of the clamping plate 144. Compared with judging the displacement of the clamping head 142 by observing the number of rotations of the hand wheel 1432, the indicator bar 1422 can intuitively display the clamping amount of the clamping plate 144, and the operator can more easily grasp the displacement of the clamping plate 144.

[0110] Furthermore, a triangular pointed tip 14221 is provided at the end of the indicator bar 1422, and the pointed tip 14221 is parallel to the tooling plate 2 so that the tip of the triangle points to the scale 24 on the tooling plate 2. When the indicator bar 1422 moves with the clamping plate 144, the pointed tip 14221 moves accordingly above the scale 24. The pointed tip 14221 can more clearly display the moving position of the indicator bar 1422 relative to the scale 24, which is beneficial for the operator to accurately and quickly read the clamping amount of the indicator bar 1422.

[0111] In some embodiments, the first clamping assembly 13 of this embodiment further includes: a pressure sensor.

[0112] It is understandable that, when the first clamping component 13 fixes one side of the battery cell module 21, the pressure sensor is used to detect whether the pressure value of the second clamping component 14 on the other side of the battery cell module 21 reaches a preset value, so as to avoid the pressure value of the second clamping module being too small, resulting in the battery cell module 21 not being squeezed into place, or the pressure value of the second clamping module being too large, resulting in damage to the battery cell module 21.

[0113] Optionally, the pressure sensor may be a piezoresistive sensor or a load sensor.

[0114] In this embodiment, by providing a pressure sensor in the first pressing assembly 13 , the pressing force on the battery cell module 21 can be adjusted according to the value of the pressure sensor, so that the pressing force on the battery cell module 21 is more accurate and reliable.

[0115] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
