[0039] In the above structure, the auxiliary tooling for sticking insulating paper on the end plate includes a bottom plate 1, an upper limit block 2, a lower limit block, a left limit block and a right limit block, and the upper limit block 2, the lower limit block, the left limit block and the right limit block are installed on the bottom plate 1. The upper limit block 2 and the lower limit block are in the horizontal direction, and the upper limit block 2 and the lower limit block are opposite to each other up and down. The left limit block and the right limit block are in the vertical direction, and the left limit block and the right limit block are opposite to each other left and right.

[0040] The upper limit block 2 and the lower limit block include a bottom step and a top step. In the up-down direction, the size of the bottom step is smaller than the size of the top step, and a step surface is formed between the two. In the left-right direction, the size of the left limit block and the right limit block are equal, and the sides of the left limit block and the right limit block are flush. After connection, the left and right sides of the end plate 6 and the insulating paper 7 are parallel and flush. Figure 6 The thick line portion indicates the relative distance of the insulating paper 7 being offset, the left and right sides of the end plate 6 and the insulating paper 7 are not flush, and the steel strip 9 is not easy to be placed in the slot of the end plate 6.

[0041] The area enclosed by the bottom step of the limit block is the end plate placement area, and the end plate 6 is placed on the bottom plate 1 where the end plate placement area is located. The surface of the bottom plate 1 is a plane, and the bottom plate 1 is provided with avoidance holes at positions corresponding to the ribs of the end plate 6, and the end plate 6 is in flat contact with the bottom plate 1. The area enclosed by the top step is the insulating paper placement area 10 domain, and the insulating paper 7 is placed on the step surface where the insulating paper placement area 10 domain is located. The height from the bottom plate 1 to the step surface is the same as the thickness of the end plate 6, that is, the bottom surface of the insulating paper 7 is in contact with the surface of the end plate 6. The step surface is parallel to the bottom plate 1, and the insulating paper 7 is in complete contact with the end plate 6, ensuring that the insulating paper 7 and the end plate 6 are bonded flat.

[0042] When the end plate 6 is placed on the bottom plate 1 where the end plate placement area is located, each side of the end plate 6 is respectively fitted with the inner side of the bottom step of the corresponding limit block, and the upper limit block 2, the lower limit block, the left limit block and the right limit block limit the position of the end plate 6 in four directions. At the same time, when the insulating paper 7 is placed on the step surface where the insulating paper placement area 10 is located, the insulating paper 7 falls on the surface of the end plate 6, the insulating paper 7 is bonded to the end plate 6, and each side of the insulating paper 7 is respectively fitted with the inner side of the top step of the corresponding limit block, and the upper limit block 2, the lower limit block, the left limit block and the right limit block limit the position of the insulating paper 7 in four directions.

[0043] The upper limit block 2, the lower limit block, the left limit block and the right limit block simultaneously limit the position of the end plate 6 and the insulating paper 7, and the relative position of the end plate 6 and the insulating paper 7 is fixed, ensuring the consistency of the position of the insulating paper 7 on the end plate 6 each time. After the connection, the left and right sides of the end plate 6 and the insulating paper 7 are parallel and flush, and the bonding surface of the insulating paper 7 and the end plate 6 is flat, which improves the accuracy of the position of the insulating paper 7 on the end plate 6, can speed up the efficiency of sticking the insulating paper 7 on the end plate 6, and reduce the sample preparation time of the end plate 6.

[0044] By applying the technical solution provided in the embodiment of the utility model, before the modules are stacked, the insulating paper 7 is attached to the end plate 6, and then the end plate 6 is placed on the end plate 6 fixing block of the extrusion station, and the battery cell 8 is squeezed to the fixed end plate 6 fixing block through the movable end plate 6 fixing block, and then the module is squeezed to an overpressure state, and the steel belt 9 is placed in the end plate 6 card slot. After the movable end extrusion block returns to the original position, the entire module sleeve steel belt 9 action is completed. When the insulating paper 7 attached to the end plate 6 is squeezed to the predetermined pressure value position with good consistency, it is easy to place the steel belt 9 in the end plate 6 card slot, which reduces the difficulty of the module sleeve steel belt 9 and increases the efficiency of the module sleeve steel belt 9.

[0045] Based on the above specific embodiment, the lower limit block includes a first lower limit block and a second lower limit block. The first lower limit block is connected with the left limit block to form a first combined limit block 3, and the second lower limit block is connected with the right limit block to form a second combined limit block 5.

[0046] In a specific embodiment, the upper limit block 2 is a whole block, located between the left limit block and the right limit block. The lower limit block includes two sub-limit blocks, and the first lower limit block and the second lower limit block are respectively located on both sides of the lower end of the end plate 6. The first lower limit block is connected with the left limit block to form a first combined limit block 3, and the second lower limit block is connected with the right limit block to form a second combined limit block 5. Specifically, the first lower limit block and the left limit block can be an integral structure, and the second lower limit block and the right limit block can be an integral structure. When in use, the upper limit block 2 is fitted with the upper side of the end plate 6 and the insulating paper 7, and both sides of the first combined limit block 3 and the second combined limit block 5 are right-angled, one side is fitted with one right-angle side of the end plate 6 and the insulating paper 7, and the other side is fitted with the other right-angle side of the end plate 6 and the insulating paper 7.

[0047] In the above embodiment, the first combined limit block 3 and the second combined limit block 5 have both upper and lower limit and left and right limit functions, which reduces the number of limit blocks and makes the installation and adjustment of the limit blocks easier.

[0048] On the basis of the above-mentioned specific embodiments, a positioning column 4 is provided on the bottom plate 1 , and a positioning blind hole matching the positioning column 4 is provided on the side of the end plate 6 in contact with the bottom plate 1 , and the positioning blind hole is sleeved on the positioning column 4 .

[0049] In a specific embodiment, the positioning blind hole of the end plate 6 corresponds to the position of the positioning column 4 of the bottom plate 1. When the end plate 6 is placed, the side with the positioning blind hole contacts the bottom plate 1, and the positioning blind hole is mounted on the positioning column 4 to determine the relative position of the end plate 6 and the bottom plate 1. The positioning column 4 has an anti-mistake effect to prevent the insulating paper 7 from being pasted on the wrong side due to the end plate 6 being placed upside down. It should be noted that when the positioning blind hole is not in the center of the end plate 6, after the positioning column 4 is connected to the positioning blind hole, it also has the function of preventing the upper and lower ends of the end plate 6 from being placed upside down, thereby realizing an anti-mistake design.

[0050] Preferably, the positioning blind hole and the positioning column 4 are clearance-matched, which can not only facilitate the positioning column 4 to enter the positioning blind hole, but also reduce the relative shaking and displacement of the end plate 6 and the bottom plate 1, thereby ensuring the accuracy of the positioning of the end plate 6.

[0051] Furthermore, the cross-sections of the positioning blind holes and the positioning posts 4 are square, which reduces the relative rotation between the end plate 6 and the bottom plate 1 .

[0052] Preferably, the bottom plate 1 has a threaded hole, and a pin is connected in the threaded hole. The pin forms a positioning column 4, which has a simple structure and is easy to connect.

When the number of the positioning blind holes is two, there are two positioning blind holes, and the center line of the two positioning blind holes is not colinear with the center point of the bottom surface of the end plate 6, that is, the connection position of the end plate 6 and the bottom plate 1 is uniquely determined. When the end plate 6 is placed upside down, the positioning blind hole cannot be connected to the positioning column 4 of the bottom plate 1, thereby preventing the insulating paper 7 from being pasted in the wrong direction due to the end plate 6 being placed upside down.

[0054] In another specific embodiment, the number of the positioning blind holes is three or more. When all the positioning blind holes are not collinear or the spacing between them is not equal, it can be ensured that the connection position of the end plate 6 and the bottom plate 1 is uniquely determined, and the end plate 6 will not be installed upside down.

[0055] Based on the above-mentioned specific embodiments, there are vertical waist-shaped holes on the left limit block and the right limit block, and there are connecting holes on the bottom plate 1 that match the vertical waist-shaped holes. The fasteners are connected to the vertical waist-shaped holes and the connecting holes, and the fasteners are slidably connected to the vertical waist-shaped holes.

[0056] In a specific embodiment, the limiting block and the base plate 1 are detachably connected, for example, by fasteners, which is convenient to connect and easy to disassemble.

[0057] The upper limit block 2 is fixed to the bottom plate 1, and the first combined limit block 3 and the second combined limit block 5 are provided with vertical waist-shaped holes, specifically, the left limit block and the right limit block are provided with vertical waist-shaped holes, and the vertical waist-shaped holes are consistent with the length direction of the left limit block and the right limit block, which is convenient to open. The fasteners are connected to the vertical waist-shaped holes and the connecting holes, and the fasteners are loosened, and the vertical waist-shaped holes can slide up and down along the fasteners, so as to adjust the vertical positions of the first combined limit block 3 and the second combined limit block 5, that is, to achieve the position adjustment of the first lower limit block and the second lower limit block, so as to adapt to the end plates 6 of different lengths and expand the scope of use.

[0058] On the basis of the above-mentioned specific embodiments, the connecting hole is a transverse waist-shaped hole, and the fastener is slidably connected to the transverse waist-shaped hole.

[0059] In a specific embodiment, the connection hole on the bottom plate 1 is a transverse waist-shaped hole. When the fastener is loosened, the transverse waist-shaped hole can slide up and down along the fastener to adjust the transverse position of the first combined limit block 3 and the second combined limit block 5, that is, to achieve the position adjustment of the left limit block and the right limit block, so as to adapt to the end plates 6 of different widths. The transverse waist-shaped hole and the vertical waist-shaped hole form a cross hole, and the transverse waist-shaped hole and the vertical waist-shaped hole realize the dual adjustment of the transverse position and the vertical position of the first combined limit block 3 and the second combined limit block 5, which has a wider range of use and is more convenient to use.

[0060] Based on the above-mentioned specific embodiments, the base plate 1 includes an outer frame plate and an intermediate plate, the upper limit block 2, the lower limit block, the left limit block and the right limit block are installed on the outer frame plate, the end plate 6 is placed on the intermediate plate, and a lifting device is provided at the bottom of the intermediate plate for adjusting the step surface to be flush with the surface of the end plate 6 when the step surface is not flush with the surface of the end plate 6.

[0061] In actual application, the bottom plate 1 is a split structure, including an outer frame plate and an intermediate plate, and the intermediate plate is located in the opening of the outer frame plate. The upper limit block 2, the lower limit block, the left limit block and the right limit block are installed on the outer frame plate, and the depth positions of the upper limit block 2, the lower limit block, the left limit block and the right limit block are fixed. The end plate 6 is placed on the intermediate plate, and a lifting device is provided at the bottom of the intermediate plate, which drives the intermediate plate to rise and fall. When the step surface is not flush with the surface of the end plate 6, the lifting device adjusts the depth of the intermediate plate entering the outer frame plate so that the step surface is flush with the surface of the end plate 6.

[0062] In the above embodiment, the distance difference between the step surface and the middle plate is adjusted to be equal to the thickness of the end plate 6 by the lifting device, ensuring that the step surface is flush with the surface of the end plate 6 after the end plate 6 is placed on the middle plate, so that the insulating paper 7 is flatly attached to the surface of the end plate 6; it is suitable for the use of end plates 6 of different thicknesses, and the scope of application is further expanded.

[0063] More specifically, the lifting device includes a height sensor, a position sensor and a lifting mechanism. The height sensor is used to detect the height of the step surface; the position sensor is used to detect the height of the end plate 6; the lifting mechanism is connected to both the height sensor and the position sensor, and is used to control the lifting of the middle plate to make the step surface flush with the surface of the end plate 6 when the height of the step surface detected by the height sensor is not equal to the height of the end plate 6 detected by the position sensor, ensuring that the step surface is flush with the surface of the end plate 6 after the end plate 6 is placed on the middle plate, so that the insulating paper 7 is flatly attached to the surface of the end plate 6.

[0065] In actual applications, each limit block is provided with an adjusting device. When the inner side surface of the limit block is not completely in contact with the corresponding side surfaces of the end plate 6 and the insulating paper 7, the adjusting device drives the limit block to move so that the inner side surface of the limit block is completely in contact with the corresponding side surfaces of the end plate 6 and the insulating paper 7, thereby ensuring that the end plate 6 and the insulating paper 7 are accurately positioned, ensuring the consistency of the position of the insulating paper 7 on the end plate 6, and improving product quality.

[0066] Based on the above specific embodiments, the adjusting device includes:

[0067] A contact sensor for detecting whether the inner side of the limit block is in contact with the side corresponding to the end plate 6 and the insulating paper 7;

[0068] A movable adjustment mechanism connected to the contact sensor, used to control the inner side surfaces of the upper limit block 2, the lower limit block, the left limit block and the right limit block to move and fit with the corresponding side surfaces of the end plate 6 and the insulating paper 7.

[0069] In practical applications, the adjusting device includes a contact sensor and a movable adjusting mechanism, and the movable adjusting mechanism can be a telescopic cylinder or an electric push rod.

[0070] The contact sensor is arranged on the inner side of the limit block, detects whether the inner side of the limit block fits with the side corresponding to the end plate 6 and the insulating paper 7, and sends the detection result to the mobile adjustment mechanism. When the inner side of the upper limit block 2, the lower limit block, the left limit block and the right limit block do not fit with the side corresponding to the end plate 6 and the insulating paper 7, the mobile adjustment mechanism controls the movement of the inner side of the upper limit block 2, the lower limit block, the left limit block and the right limit block, so that the limit block fits with the side corresponding to the end plate 6 and the insulating paper 7, ensures that the end plate 6 and the insulating paper 7 are accurately positioned, ensures the consistency of the position of the insulating paper 7 attached to the end plate 6, and improves product quality.
