DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all embodiments of the application.

[0034] ​In the production process of the battery product, a plurality of battery cells can be assembled into a battery cell module (or a battery module), and a plurality of battery cell modules can be assembled into a battery pack. In some embodiments, the battery cell module can include a plurality of battery cells arranged in a column, and thus the battery cell module can also be referred to as a single-column battery cell. In other embodiments, the battery cell module can include a plurality of battery cells arranged in multiple columns, and thus the battery cell module can also be referred to as a multi-column battery cell.

[0035] In the production process of the battery pack, the side gluing of the battery cell module is an indispensable process in the packaging (PACK) process. The purpose is to glue the sides of a plurality of battery cell modules to increase the bonding force and ensure the stability and performance of the battery pack formed by the plurality of battery cell modules. Therefore, in the entire process, the side gluing of the battery cell module is an indispensable link.

[0036] In the related art, the packaging process of the battery pack includes: gluing the same side of a plurality of battery cell modules respectively, and then merging the plurality of battery cell modules into a battery pack including the plurality of battery cell modules by using a mechanical hand transfer mode. This process arrangement type usually occupies a large space and cannot be applied to special scenarios such as a small factory area and a compact equipment space utilization rate. However, in some special environments, such as a small factory area and a compact equipment space utilization rate, it is very difficult to arrange a battery cell gluing device that can implement the packaging process. That is, the process arrangement type in the related art usually occupies a large space and cannot be applied to special scenarios such as a small factory area and a compact equipment space utilization rate.

[0037] Therefore, the embodiments of the present application provide a battery cell gluing device which can glue at least one of a first battery cell module and a second battery cell module arranged face to face in a narrow side gap and then press the first battery cell module and the second battery cell module into a double-column battery cell module. Compared with the related art, the battery cell gluing device needs to occupy a smaller space, has a high space utilization rate, and also helps to shorten the process time and improve the production efficiency.

[0038] The following will be described in detail Figures 1-13 The battery cell gluing device 100 provided by the embodiments of the present application will be described in detail.

[0039] As shown in Figure 1 The battery cell gluing device 100 can include a rack 110, a support platform 120, a gluing device 140, and a pressing device 150.

[0040] The rack 110 can be a metal structure welded part, or also a metal profile assembly part. Generally, the rigidity and stability of the rack 110 need to meet certain requirements to prevent deformation during long-term production under load. The rack 110 is usually fixed to the ground by expansion bolts or anchor bolts.

[0041] The support platform 120 can be fixed to the ground or fixedly mounted on the frame 110. The support platform 120 has a first bearing area 121 and a second bearing area 122, which respectively bear the first battery cell module 131 and the second battery cell module 132. The first battery cell module 131 located in the first bearing area 121 and the second battery cell module 132 located in the second bearing area 122 are parallel and have a side gap S. The side gap S can refer to the gap between the first side surface 1311 of the first battery cell module 131 and the second side surface 1321 of the second battery cell module 132, that is, the first side surface 1311 and the second side surface 1321 are two sides of the first battery cell module 131 and the second battery cell module 132 facing each other, and the first side surface 1311 and the second side surface 1321 together constitute the side gap S.

[0042] It is understood that both the first cell module 131 and the second cell module 132 may include multiple cells, with the large surfaces of the multiple cells bonded together. The first cell module 131 and the second cell module 132 may be, for example, single-row cells.

[0043] In some embodiments, such as Figures 1-3 As shown, the support platform 120 may include a first drive assembly 123 (which can be understood as the aforementioned pressing device 150) capable of driving the first battery cell module 131 and / or the second battery cell module 132 to move in the x-direction, a second drive assembly 124 capable of driving the first battery cell module 131 or the second battery cell module to move in the y-direction, and a base 125. The second drive assembly 124 may be connected to the first drive assembly 123, the first drive assembly 123 is fixed to the base 125, and the first battery cell module 131 and / or the second battery cell module 132 are connected to both the second drive assembly 124 and the first drive assembly 124. For example, the first drive assembly 123 may include a first linear guide rail extending in the x-direction and a slider connected to the first linear guide rail, the first linear guide rail being fixed to the base 125; the second drive assembly 124 may include a second linear guide rail extending in the y-direction and a slider connected to the second linear guide rail; the first battery cell module 131 and the second battery cell module 132 are connected to the slider in the second drive assembly 124, and the second linear guide rail is also connected to the slider in the first drive assembly 123. By configuring these components, the support platform 120 can move the first battery cell module or the second battery cell module 132 in the x-direction and / or y-direction.

[0044] In some embodiments, the first bearing area 121 and the second bearing area 122 are located in the same plane, and the first cell module 131 and the second cell module 132 are located in the same reference plane. The size of the side gap S can be set according to application requirements, and generally needs to consider the convenience of the gluing operation, the rapid pressing, and the arrangement of the double-row transportation device and the like. For example, the distance of the side gap S can be 50mm, 80mm.

[0045] The gluing device 140 is arranged on the rack 110, or in other words, the gluing device 140 is connected with the rack 110. The application embodiments do not make specific limitations on the connection mode of the gluing device 140 and the rack 110. For example, the gluing device 140 can be movably connected with the rack 110. For example, the gluing device 140 can be connected with the rack 110 through the third linear assembly 147 in the following text, so that the gluing device 140 can move relative to the rack 110 based on the third linear assembly 147. The gluing device 140 is used for pasting the glue pad 133 on the first side surface 1311 and / or the second side surface 1321 constituting the side gap S. The glue pad 133 can be, for example, single-sided adhesive tape or double-sided adhesive tape. The glue pad 133 can be used for insulating the first cell module 313 and the second cell module 132 and / or for bonding the first cell module 313 and the second cell module 132.

[0046] The pressing device 150 can be located on the support platform 120, and the pressing device 150 can be, for example, the first driving assembly 123 on the support platform 120 which can move the first cell module 131 and / or the second cell module 132 in the first direction. The pressing device 150 is used for extruding the first cell module 131 and the second cell module 132 located in the first bearing area 121 and the second bearing area 122, respectively, in the first direction, so that the first side surface 1311 of the first cell module 131 and the second side surface 1321 of the second cell module 132 abut to form a double-row cell module.

[0047] It should be noted that the first direction is a direction in which the first cell module 131 and the second cell module 132 approach each other, and the first direction is parallel to the width direction of the side gap S, that is, the first direction is parallel to the x direction in the coordinate system shown in Figure 1 The above-mentioned y direction (or third direction) can be understood as being parallel to the length direction of the side gap S.

[0048] By executing the application embodiments, the cell gluing equipment can realize the gluing of at least one side surface of the first cell module and the second cell module arranged face to face in the narrow side gap S, and then the pressing of the first cell module and the second cell module into a double-row cell module. Compared with the related art, the gluing and pressing of the cell gluing equipment can be completed at one place, the space occupied is small, the space utilization rate is high, and it is also helpful to shorten the process time and improve the production efficiency.

[0049] The structure of the rubberizing device 140 is not specifically limited in the embodiments of the present application, as long as the rubberizing device 140 can paste the rubber pads 133 to the first side surface 1311 and / or the second side surface 1321 constituting the side gap S.

[0050] As an implementation manner, as shown in Figures 4-5 and Figures 7-11 , the rubberizing device 140 can include a cloth plate 141, a first linear assembly 143 and a second linear assembly 145.

[0051] The cloth plate 141 is configured to be rotatable to a first state and a second state, and is also called a feeding plate or a rubberizing plate. When the cloth plate 141 is in the first state (as shown in Figure 4 and Figure 8 ), the front surface (i.e., the surface to be rubberized) of the cloth plate 141 faces the operator so as to be arranged with the rubber pads 133. When the cloth plate 141 is in the second state (as shown in Figure 3 and Figure 9 ), the cloth plate 141 faces the first side surface 1311 and is parallel to the first side surface 1311, i.e., faces the first side surface 1311 so as to rubberize the first side surface 1311. Alternatively, when the cloth plate 141 is in the second state, the cloth plate 141 faces the second side surface 1321 and is parallel to the second side surface 1321, i.e., faces the second side surface 1321 so as to rubberize the second side surface 1321.

[0052] In some embodiments, the cloth plate 141 can be a vacuum sponge suction plate type cloth plate (referred to as a vacuum sponge suction plate). As shown in Figure 4 and Figures 10-11 , a plurality of hole groups 1411 can be formed on the vacuum sponge suction plate, the plurality of hole groups 1411 are used to accommodate a plurality of rubber pads 133, and the plurality of hole groups 1411 correspond to a plurality of battery cells in the first battery cell module 131 or the second battery cell module 132. The thickness of the rubber pad 133 protruding from the vacuum sponge suction plate is less than the compression amount of the rubber pad 133. The thickness of the rubber pad 133 protruding from the vacuum sponge suction plate can refer to the distance between the top surface of the rubber pad 133 and the surface of the cloth plate 141. That is, the vacuum sponge suction plate can be provided with a hole group 1411 simulating a single-sided rubber, and the rubber pad 133 can be embedded in the hole group 1411. For example, the rubber pad 133 can be a single-sided rubber, and the size of the single-sided rubber is 40*65*0.9. Therefore, the opening size of the vacuum sponge suction plate can be 41*66*0.4, and the side edge has a gap of 0.5 mm. The protruding thickness of the single-sided rubber is less than the compression amount of the single-sided rubber, which is beneficial for smooth pasting and avoids scratching the product surface.

[0053] In some embodiments, when the cloth plate 141 is provided as a vacuum suction cup, the thickness of the cloth plate 141 can be maintained between 10-20 mm, based on which the air pipe and the negative pressure hole can be arranged around without affecting the thickness space. Therefore, the vacuum suction cup type is adopted, which is compact in arrangement, can extend into a very narrow space (such as a side gap), and has a soft material that can achieve good buffering effect, reduce the impact of the first air cylinder below, and effectively avoid product scratching problems.

[0054] With reference to Figure 11 and Figure 12 continuously, the first linear assembly 143 can include a driving device 1431, a first sliding rail 1434, and a sliding block 1435. The driving device 1431 can be connected with the sliding block 1435 (referred to as the first sliding block 1435) of the first linear assembly 143, and the driving device 1431 is used to drive the first sliding block 1435 to move along the extension direction of the first sliding rail 1434. The extension direction of the first sliding rail 1434 is the first direction. The first sliding block 1435 can be connected with the cloth plate 141, and the first linear assembly 143 can move the cloth plate 141 along the first direction, so that the rubber pad 133 on the cloth plate 141 in the second state is pasted to the first side surface 1311 or the second side surface 1321.

[0055] In some embodiments, the driving device 1431 can be a first air cylinder. The connection mode of the driving device 1431 and the first sliding block 1435 is not specifically limited in the embodiments of the present application. For example, the driving device 1431 can be directly connected with the first sliding block 1435. For another example, the driving device 1431 can be connected with the first sliding block 1435 through other components. As an example, in combination with Figure 11 and Figure 12 shown, when the driving device 1431 is a first air cylinder, the rod 1432 of the first air cylinder can be connected with the first mounting plate 1436 that fixes the first sliding block 1435 through the connecting block 1433.

[0056] In some embodiments, as shown in Figure 11 and Figure 12 , the first sliding rail 1434 and the driving device 1431 are fixedly installed on the second mounting plate 1437, and the second mounting plate 1437 is fixedly connected with the sliding block 1454 of the second linear assembly 145. The second mounting plate 1437 is parallel to the first mounting plate 1436. The second mounting plate 1437 can be arranged to move the first linear assembly 143 and the cloth plate 141 together along the second direction under the control of the second linear assembly 145. The second mounting plate 1437 and the first mounting plate 1436 are arranged together to move the cloth plate 141 along the first direction under the control of the first linear assembly 143.

[0057] In order to avoid the situation that the pushing force of the driving device 1431 is too large when the rubberizing device 140 is rubberizing, and the first battery module or the second battery module is impacted. In some embodiments, as shown in Figure 3 and Figures 8-12 illustrated, the rubberizing device 140 further includes a buffer 1438. The buffer 1438 is fixedly installed on the second mounting plate 1437 through a connecting piece 1439. The buffer end 1440 of the buffer 1438 faces the first mounting plate 1436. As shown in Figure 3 , the buffer end 1439 abuts against the first mounting plate 1436 before the rubber pad 133 on the cloth plate 141 abuts against the first side surface 1311 or the second side surface 1321. After abutting, the buffer 1439 can exert a resistance on the first mounting plate 1436, thereby reducing the impact force of the cloth plate 141 connected with the first mounting plate 1436 on the first side surface 1311 and / or the second side surface 1321, so that the impact force is less than a preset threshold. That is, the buffer 1439 is used to make the pressure that the first side surface 1311 or the second side surface 1321 receives when the rubber pad 133 is pasted less than a preset threshold, thereby achieving a buffering effect.

[0058] As shown in Figure 3 and Figure 4 , the second linear assembly 145 can include a sliding block 1454. The sliding block 1454 of the second linear assembly 145 can be simply referred to as the second sliding block 1454. The first linear assembly 143 is arranged on the second sliding block 1454, and the second linear assembly 145 can move the cloth plate 141 in a second direction to enter and / or exit the side gap S.

[0059] As an implementation manner, the second linear assembly 145 can further include a second driving device, for example, including a second cylinder 1451 and a second sliding rail 1452 as shown in Figure 4 . The second cylinder 1451 is connected with the second sliding rail 1452 and is used to drive the second sliding block 1454 to move along the second sliding rail 1452. The extension direction of the second sliding rail 1452 is the second direction.

[0060] It should be noted that the second direction is perpendicular to the first direction and the third direction, and the second direction is parallel to the thickness direction of the side gap, that is, the second direction can be the z direction in Figure 1 .

[0061] In some embodiments, the second linear assembly 145 can further include a base bracket 1453 and an adapter assembly 1455. The second cylinder 1451 and the second sliding rail 1452 are both fixedly arranged on the base bracket 1453. The adapter assembly 1455 is used to fixedly connect the extension rod of the second cylinder 1451 and the second sliding block 1454.

[0062] In some embodiments, asFigure 2 and Figure 3 As shown in FIG. 13, the first battery cell module 131 is a battery cell module far from the operator, the second battery cell module 132 is a battery cell module close to the operator, the first side surface is toward the operator, and the adhesive device 140 is used to paste the adhesive pad 133 on the first side surface 1311. Through the above arrangement, the operator can conveniently check the pasting effect of the adhesive pad, and the yield of the double-row battery cell module generated by the battery cell adhesive device can be improved.

[0063] In the embodiment of the present application, the adhesive device 140 is arranged to include the cloth plate 141, the first linear assembly 143 and the second linear assembly 145, so that the position of the cloth plate 141 can be automatically adjusted, and the first side surface and / or the second side surface can be pasted with the adhesive pad in the side gap. The structure layout is compact and can improve the adhesive efficiency.

[0064] As described above, the cloth plate 141 can be configured to rotate to the first state and the second state. As an implementation manner, in combination with Figure 3 , Figure 5 and Figures 7-9 As shown in FIG. 14, the adhesive device 140 further includes a rotating assembly 142. The rotating assembly 142 is connected with the cloth plate 141, and the rotating assembly 142 drives the cloth plate 141 to rotate around the axis of the rotating assembly 142.

[0065] It should be noted that the extension direction of the axis of the rotating assembly 142 is parallel to the length direction of the side gap S, that is, the extension direction of the axis of the rotating assembly 142 is the y direction in Figure 1 .

[0066] The fixing manner of the rotating assembly 142 is not limited in the embodiment of the present application. As an implementation manner, as shown in Figures 7-11 , the adhesive device 140 can further include a fixing support 144, and the fixing support 144 is fixedly connected with the first sliding block 1435. As shown in Figure 8 and Figure 9 , the fixing support 144 is provided with a first hole portion 1441, the axis of the first hole portion 1441 extends along the y direction, and the rotating assembly 142 is supported on the first hole portion 1441. The first sliding block 1435 drives the fixing support 144, the rotating assembly 142 and the cloth plate 141 to move together along the first direction. Alternatively, as shown in Figures 7-11 , the fixing support 144 can be fixed on the first mounting plate 1436. Since the first mounting plate 1436 is fixed with the first sliding block 1435 and the fixing support 144 at the same time, it is equivalent to that the fixing support 144 is fixedly connected with the first sliding block 1435.

[0067] In some embodiments, as shown in Figure 7As shown, the rotating assembly 142 includes a rotating transmission assembly 1421, a support bracket 1422, and a bearing 1423. The rotating transmission assembly 1421 includes, in sequence along the extension direction of the axis of the rotating assembly 142, a motor 1425, a speed reducer 1426, a shaft coupling 1427, and a connecting shaft 1424. The support bracket 1422 is connected with the connecting shaft 1424 through the bearing 1423, and the rotating assembly 142 is supported on the first hole portion 1441 through the bearing 1423. The support bracket 1422 is connected with the cloth plate 141. The speed reducer 1426 can be a directly connected speed reduction motor, or a motor and a reducer connected in two parts. The motor 1425 can be a servo motor, which can be a direct current motor or an alternating current motor.

[0068] With respect to the arrangement that the cloth plate 141 is directly fixed to the first slider 1435 and the rotating assembly 142 respectively, the embodiment of the present application achieves the mode of fixing the rotating assembly 142 on which the cloth plate 141 is installed to the slider 1435 of the first linear assembly 143 through the support bracket 1422, the first mounting plate 1436, and the fixing bracket 144, which is compact in installation and has a smaller swing space of the cloth plate 141, and is helpful to reduce the interference with other components.

[0069] As described above, the first linear assembly 143 can move the cloth plate 141 in the first direction. In some scenarios, for example, when the first linear assembly 143 is installed using the first mounting plate 1436 and the second mounting plate 1437, the distance by which the cloth plate 141 can be moved in the first direction by the first linear assembly 143 is usually limited due to the size and layout of the battery cell rubberizing device.

[0070] To further increase the moving space of the cloth plate 141 in the first direction, in some embodiments, as shown in Figure 1 、 Figure 3 and Figure 6 , the battery cell rubberizing device 100 can further include a third linear assembly 147 fixedly arranged on the rack 110. The third linear assembly 147 includes a slider 1471, and the rubberizing device 140 is connected with the slider 1471 (referred to as the third slider 1471) of the third linear assembly 147. The third linear assembly 147 can move the third slider 1471 to adjust the distance between the cloth plate 141 and the operator, and / or the relative position of the cloth plate 141 and the side gap S in the first direction. That is, the third linear assembly can adjust the moving position of the rubberizing device 140 connected therewith in the first direction.

[0071] As an implementation manner, the third linear assembly 147 further includes a third driving device for driving the third slider 1471 to move in the first direction. The third driving device is fixedly installed on the top of the rack 110. The third driving device can include, for example,Figure 1 、 Figure 3 and Figure 6 The servo module 1472 extends along the first direction and is arranged on the top of the rack 110. The third sliding block 1471 comprises a third sliding block 1471a in sliding connection with the servo module 1472, and the third sliding block 1471a is fixedly connected with the gluing device 140. The servo module 1472 contains a servo motor and a transmission system, the transmission system is in sliding connection with the third sliding block 1471a, and the servo motor can drive the transmission system to drive the third sliding block 1471a to move in the first direction, and the third sliding block 1471a can drive the gluing device 140 to move in the first direction. This arrangement can achieve a greater movement stroke of the gluing device 140 in the first direction while having a simple overall structure and a compact overall architecture.

[0072] Optionally, the third driving device further comprises a third sliding rail 1473 as shown in Figure 1 and Figure 6 The third sliding block 1471 comprises a third sliding block 1471b in sliding connection with the third sliding rail 1473. The third sliding rail 1473 and the servo module 1472 are respectively located at both ends of the gluing device 140 in the y direction. The third sliding rail 1473 also extends along the first direction and is arranged on the top of the rack 110. The third sliding block 1471b is fixedly connected with the gluing device 140, and when the servo module 1472 drives the third sliding block 1471a to move in the first direction, the third sliding block 1471a can also drive the gluing device 140 and the third sliding block 1471b to move in the first direction. By additionally providing the third sliding rail 1473 and the third sliding block 1471b, the movement stroke of the gluing device 140 in the first direction can be increased while the support stability of the gluing device 140 can be improved.

[0073] In order to further realize the automatic detection of the gluing effect and the pressing effect, in some embodiments, as shown in Figure 1 The battery cell gluing equipment 100 can further comprise a visual detection module 160. The visual detection module 160 is arranged on the rack 110, and the visual detection module 160 is used to detect the gluing effect on the first side surface 1311 and / or the second side surface 1321.

[0074] As an example, as shown in Figure 13As shown, the visual detection module 160 can include a fourth linear assembly 161, a plurality of light sources 162 and a camera 163. The plurality of light sources 162 and the camera 163 are both arranged on the fourth linear assembly 161, and the fourth linear assembly 161 can control (or drive) the plurality of light sources 162 and the camera 163 to move in the x direction and / or the z direction. Based on this, the plurality of light sources 162 and the camera 163 can be moved in the x direction and / or the z direction. Among them, the camera 163 is located in the central region of the plurality of light sources 162 to provide light sources for shooting. Through this setting, the positions of the plurality of light sources 162 and the camera 163 can be adjusted to obtain a better shooting angle, thereby helping to improve the visual detection result.

[0075] The embodiments of the present application do not make specific limitations on the structure of the fourth linear assembly 161. As an implementation manner, as shown in Figure 13 As shown, the fourth linear assembly 161 further includes a fourth x-axis linear assembly 1612 and a fourth z-axis linear assembly 1613. The fourth x-axis linear assembly 1612 includes a fourth sliding block 1611 and an x-axis visual servo module 1615 for driving the fourth sliding block 1611 to move in the x direction. The fourth z-axis linear assembly 1613 includes a fifth sliding block 1614 and a z-axis sliding rail 1616 and a z-axis motor 1617 for driving the fifth sliding block 1614 to move in the z direction. The fourth z-axis linear assembly 1613 can be fixedly connected with the fourth sliding block 1611, so that when the x-axis visual servo module 1615 drives the fourth sliding block 1611 to move in the x direction, the fourth z-axis linear assembly 1613 as a whole can move in the x direction. The z-axis motor 1617 is connected with the fifth sliding block 1614 and drives the fifth sliding block 1614 to move along the extension direction of the z-axis sliding rail 1616, and the extension direction of the z-axis sliding rail 1616 is the z direction. Through this setting, the positions of the camera and the light source can be adjusted in multiple directions while ensuring that the overall structure is compact.

[0076] In order to avoid the shooting dead angle of the visual detection device 150 and avoid the influence of the front placement of the visual detection device 150 on the operation field of view of the operator, in some embodiments, as shown in Figure 1 As shown, the visual detection module 160 can be fixed on the two sides of the y direction of the rack 110, so that the visual detection modules 160 symmetrically arranged on the two sides of the y direction of the rubberizing device 140 in the y direction respectively shoot from the two side edges of the first or second battery cell module 131 or 132.

[0077] In order to make the visual detection device 150 be arranged at an inclined angle, so as to further avoid the shooting dead angle. In some embodiments, as shown in Figure 1 As shown, the fourth z-axis linear assembly 1613 can be fixed on the sliding block 1611a through an inclined bracket 1621, and the inclination angle makes the camera 163 and the plurality of light sources 162 can be inclined to align with the rubberizing position or the pressing position.

[0078] To achieve further fine-tuning of the position of the camera 163. In some embodiments, as shown in FIG. 16B, the visual detection module 160 can further include a camera fine-tuning assembly 1618. The camera fine-tuning assembly 1618 can include a linear module 1618a and a connecting piece 1618b capable of being driven by the linear module 1618a to move linearly, and the connecting piece 1618b is fixedly connected with the camera 163, so as to realize fine-tuning of the position of the camera 163 in the horizontal direction. Figure 13 To achieve further fine-tuning of the position of the plurality of light sources 162. In some embodiments, as shown in FIG. 16C, the visual detection module 160 can further include a light source fine-tuning assembly 1619. The light source fine-tuning assembly 1619 can include a pneumatic cylinder 1619a and a connecting block group 1619b connected with the pneumatic cylinder 1619a. Each connecting block in the connecting block group 1619b is fixedly connected with a light source 162, so as to realize fine-tuning of the position of the plurality of light sources 162 in the horizontal direction.

[0079] Figure 13 Optionally, as shown in FIG. 16D, the fourth z-axis linear assembly 1613, the plurality of light sources 162, the camera 163, the camera fine-tuning assembly 1618, and the light source fine-tuning assembly 1619 are all connected on the fifth slide 1614 through an intermediate plate 1620.

[0080] Optionally, as shown in FIG. 16D, the fourth z-axis linear assembly 1613, the plurality of light sources 162, the camera 163, the camera fine-tuning assembly 1618, and the light source fine-tuning assembly 1619 are all connected on the fifth slide 1614 through an intermediate plate 1620. Figure 13 The operation process of the battery cell rubberizing device 100 described above will be further described below. Specifically, the rubberizing-pressing operation of the battery cell rubberizing device 100 mainly includes the following steps.

[0081] In step 1, the initial position of the vacuum sponging sucker (i.e., the cloth distribution plate 141) faces the operator. That is, the vacuum sponging sucker is in the first state. Preferably, the vacuum sponging sucker can be rotated at an angle to make the vacuum sponging sucker in an inclined state facing the operator, so that the inclination can be consistent with the ergonomic design and be conducive to operation. In addition, the third linear assembly 147 can also move the vacuum sponging sucker to a suitable distance from the operator, so that the operator can arrange the rubber pad 133 on the vacuum sponging sucker. The rubber pad 133 can be, for example, single-sided adhesive tape or double-sided adhesive tape.

[0082] In step 2, the staff attaches the rubber pads 133 to the vacuum sponging sucker piece by piece. This operation can be performed before the first battery cell module and / or the second battery cell module arrive at this process, without waiting for other operations, so as to be completed in advance, which helps to save preparation time and improve the efficiency of the rhythm.

[0083]

[0084] ​​In step 3, the motor 1425 in the rotating assembly 142 drives the vacuum suction cup carrying the rubber pad 133 to rotate 180°. The purpose is to make the adhesive side of the cloth plate 141 face the operator, so that the operator can visually check whether the rubber pad is properly attached. It should be noted that if the opposite side is attached, it will not be convenient for manual visual inspection.

[0085] In step 4, the first linear assembly 143 and / or the third linear assembly 147 moves the vacuum suction cup so that the vacuum suction cup moves above the side gap.

[0086] In step 5, the second cylinder 1451 in the second linear assembly 145 extends so that the vacuum suction cup is lowered to a reasonable height. For example, the reasonable height is a position suitable for attaching the rubber pad to the first side of the first battery cell module 131.

[0087] In step 6, the first cylinder 1431 in the first linear assembly 143 extends to drive the vacuum suction cup to move in the x direction so as to attach the rubber pad 133 on the vacuum suction cup to the first side of the first battery cell module 131.

[0088] In step 7, after a certain period of time, the vacuum is cut off, and the rubber pad 133 is adhered to the first side of the first battery cell module 131.

[0089] In step 8, the visual inspection device 160 is used to take pictures to detect the effect of attaching the rubber pad.

[0090] In step 9, the pressing device 150 presses the first battery cell module 131 and the second battery cell module 132 respectively located in the first bearing area and the second bearing area, so as to bond the sides of the first battery cell module 131 and the second battery cell module 132 to form a double-row battery cell module.

[0091] In step 10, reset to prepare for the next cycle of operation. The reset includes: the first cylinder 1431 in the first linear assembly 143 retracts, and the vacuum suction cup is separated from the first side of the first battery cell module 131. The second cylinder 1451 in the second linear assembly 145 retracts so that the lower end of the vacuum suction cup is away from the side gap between the two rows of battery cell modules. The rotating assembly 142 rotates the vacuum suction cup from the second state to the first state facing the operator to facilitate the operator to lay the rubber pad.

[0092] The first side of the first battery cell module facing the operator is glued in the embodiment of the application, so as to facilitate the operator to check the gluing effect of the rubber pad. After the single-row battery cell module is glued, it is not necessary to be transferred to the next station, and the two single-row battery cell modules can be pressed to form a double-row battery cell module at the same station. In the embodiment of the application, the manual gluing operation time does not affect the process timing of the equipment, and the automatic rotation gluing is helpful to improve the production rhythm. Compared with the scheme in which the side gluing and pressing stations are independently arranged, the space occupied is smaller, the space utilization rate is high, the process time is shortened, and the production efficiency is improved.
