[0034] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present invention will be described in detail.

[0035] Refer to Figures 1 to 8 As shown, it shows an embodiment of the cell adhesive pasting device and the battery production equipment of the present invention. The cell adhesive pasting device includes a loading mechanism 1, a first positioning mechanism 2, a transfer mechanism 3, and an adhesive tearing mechanism 4. The loading mechanism 1 is used for storing the adhesive part 91; the first positioning mechanism 2 is used for placing the adhesive part 91; the transfer mechanism 3 includes a first transfer mechanism 31 and a second transfer mechanism 32 both for moving the adhesive part 91; the adhesive tearing mechanism 4 includes a first adhesive tearing mechanism 41 and a second adhesive tearing mechanism 42 both for tearing off the release paper of the adhesive part 91. Among them, the first transfer mechanism 31 sucks the adhesive part 91 of the loading mechanism 1 and places it on the first positioning mechanism 2. The first adhesive tearing mechanism 41 tears off the release paper at the bottom of the adhesive part 91. The second transfer mechanism 32 sucks the adhesive part 91 on the first positioning mechanism 2 and pastes it on the cell 92 of the conveyor line 5. The second adhesive tearing mechanism 42 tears off the release paper at the top of the adhesive part 91.

[0036] Specifically, the battery cell gluing device is used to automatically tear off the release paper at the bottom of the adhesive member 91 and paste the adhesive member 91 onto the battery cell 92, and then tear off the release paper at the top of the adhesive member 91 for the next step, so that the top of the adhesive member 91 is pasted onto the end plate, realizing the fixed connection between the battery cell 92 and the end plate; wherein, the adhesive member 91 may refer to a paste connecting member with insulating and heat-conducting functions such as double-sided tape, heat-conducting structural adhesive, mica sheet (PC sheet), etc. In this embodiment, the adhesive member 91 refers to a PC sheet, and the bottom and top of the PC sheet are respectively pasted on the battery cell 92 and the end plate.

[0037] The battery cell gluing device includes a loading mechanism 1, a first positioning mechanism 2, a transfer mechanism 3 and a glue tearing mechanism 4. The loading mechanism 1 is used to store the adhesive members 91. An operator stacks multiple adhesive members 91 onto the loading mechanism 1, and multiple adhesive members 91 are stored in the loading mechanism 1 for convenient automatic feeding; the first positioning mechanism 2 is used to place a single adhesive member 91, so as to facilitate tearing off the release paper of each adhesive member 91; the transfer mechanism 3 is used to suck and move the adhesive member 91. The transfer mechanism 3 includes a first transfer mechanism 31 and a second transfer mechanism 32. The first transfer mechanism 31 is used to suck the adhesive member 91 from the loading mechanism 1 and place it on the first positioning mechanism 2; the second transfer mechanism 32 is used to suck the adhesive member 91 from the first positioning mechanism 2 and paste it onto the battery cell 92 on the conveyor line 5. The conveyor line 5 refers to the conveyor line 5 for feeding the battery cells 92. Multiple battery cells 92 are arranged at intervals on the conveyor line 5 and move with the movement of the conveyor line 5; the glue tearing mechanism 4 is used to tear off the release paper on the adhesive member 91. The glue tearing mechanism 4 first clamps the release paper on the adhesive member 91, and then tears off the release paper from the adhesive member 91 by moving the glue tearing mechanism 4; the glue tearing mechanism 4 includes a first glue tearing mechanism 41 and a second glue tearing mechanism 42. The first glue tearing mechanism 41 is used to tear off the release paper at the bottom of the adhesive member 91, and the second glue tearing mechanism 42 is used to tear off the release paper at the top of the adhesive member 91. Among them, the first glue tearing mechanism 41 tears off the release paper at the bottom of the adhesive member 91 on the first positioning mechanism 2, and the second glue tearing mechanism 42 tears off the release paper at the top of the adhesive member 91 pasted on the battery cell 92 on the conveyor line 5.

[0038] When the battery cell gluing device is started, the first transfer mechanism 31 moves to the position where the loading mechanism 1 is located, sucks a single adhesive part 91 from the loading mechanism 1, and moves to the first positioning mechanism 2, places the single adhesive part 91 on the first positioning mechanism 2. Then, the first tape peeling mechanism 41 moves to the first positioning mechanism 2 and peels off the release paper at the bottom of the adhesive part 91 located on the first positioning mechanism 2. After the release paper at the bottom of the adhesive part 91 is peeled off, the second transfer mechanism 32 moves to the position where the first positioning mechanism 2 is located, sucks the adhesive part 91 located on the first positioning mechanism 2, moves the adhesive part 91 to the conveyor line 5, and pastes the adhesive part 91 onto the battery cell 92 on the conveyor line 5, thereby realizing the automatic pasting of the adhesive part 91 and the battery cell 92. At the same time, the second tape peeling mechanism 42 is further controlled to move to the conveyor line 5 to peel off the release paper at the top of the adhesive part 91 pasted on the battery cell 92 on the conveyor line 5. Therefore, the battery cell gluing device finally realizes the automatic peeling of the release paper at the top and bottom of the adhesive part 91, and pastes the adhesive part 91 on the battery cell 92, realizing the gluing and tape peeling processes for the battery cell 92.

[0039] In this embodiment, by setting the loading mechanism 1, the first positioning mechanism 2, the first transfer mechanism 31, the second transfer mechanism 32, the first tape peeling mechanism 41 and the second tape peeling mechanism 42, the automatic peeling of the release paper of the adhesive part 91 and the pasting of the adhesive part 91 onto the battery cell 92 located on the conveyor line 5 are realized. The whole process is automated, reducing the use of manual labor and improving production efficiency. At the same time, quality problems such as deviation of the gluing position, wrinkle of the colloid, breakage and residue of the colloid or scratching caused by manual operation of the product are avoided, thereby improving the product quality of the adhesive part 91 pasted onto the battery cell 92.

[0040] More specifically, as shown in Figure 1 The first positioning mechanism 2 is located on one side of the loading mechanism 1, and the first transfer mechanism 31 moves above the space between the loading mechanism 1 and the first positioning mechanism 2. At the same time, the first positioning mechanism 2 is also located on one side of the conveyor line 5, and the second transfer mechanism 32 moves above the space between the first positioning mechanism 2 and the conveyor line 5. The first transfer mechanism 31 and the second transfer mechanism 32 are arranged adjacent to each other, thereby improving the integration of the first positioning mechanism 2, the loading mechanism 1, the first transfer mechanism 31, the second transfer mechanism 32, the first tape peeling mechanism 41 and the second tape peeling mechanism 42, ensuring that the movements of each mechanism do not interfere with each other. At the same time, the battery cell gluing device makes full use of the utilization rate of the machine platform space and avoids waste of space.

[0041] In one embodiment, referring to Figure 1 and Figure 2 as shown, the battery cell gluing device further includes a first vision detection mechanism 61, and the first vision detection mechanism 61 is located between the first positioning mechanism 2 and the conveyor line 5; wherein, the second transfer mechanism 32 sucks and moves the adhesive member 91 to the first vision detection mechanism 61, and the first vision detection mechanism 61 detects whether the release paper at the bottom of the adhesive member 91 is completely peeled off. Specifically, the battery cell gluing device further includes a first vision detection mechanism 61, and the first vision detection mechanism 61 is used to detect whether the release paper at the bottom of the gluing member is completely peeled off. Among them, the bottom of the gluing member with the release paper completely peeled off is black, and the bottom of the gluing member with the release paper not peeled off is white; the first vision detection mechanism 61 is located between the first positioning mechanism 2 and the conveyor line 5, so as to facilitate the first vision detection mechanism 61 to detect the adhesive member 91 with the bottom release paper peeled off located at the first positioning mechanism 2; wherein, when the battery cell gluing device is started, after the adhesive member 91 located at the first positioning mechanism 2 has its bottom release paper peeled off by the first adhesive peeling mechanism 41, the second transfer mechanism 32 moves to the first positioning mechanism 2, sucks the adhesive member 91, and sucks and holds the adhesive member 91 to move to the position where the first vision detection mechanism 61 is located, so that the first vision detection mechanism 61 detects whether the release paper at the bottom of the adhesive member 91 is completely peeled off according to the color of the adhesive member 91. If the release paper at the bottom of the adhesive member 91 is completely peeled off, then the second transfer mechanism 32 continues to suck the adhesive member 91 to the battery cell 92 on the conveyor line 5 and pastes the adhesive member 91 to the battery cell 92; if the release paper at the bottom of the adhesive member 91 is not completely peeled off, then the second transfer mechanism 32 sucks the adhesive member 91 to the first defective product location.

[0042] Therefore, in this embodiment, the bottom release paper of the adhesive member 91 is detected according to the first vision detection mechanism 61, thereby improving the product quality and ensuring that the adhesive member 91 can be successfully pasted onto the battery cell 92.

[0043] In a specific embodiment, the cell gluing device further includes a second vision detection mechanism (not shown in the figure), and the second vision detection mechanism is located on one side of the second tape peeling mechanism 42; wherein, the conveyor line 5 conveys the cell 92 with the adhesive member 91 pasted thereon to the second vision detection mechanism, and the second vision detection mechanism detects whether the release paper on the top of the adhesive member 91 has been completely peeled off. Specifically, the cell gluing device further includes a second vision detection mechanism, and the second vision detection mechanism is used to detect whether the release paper on the top of the gluing member has been completely peeled off. Among them, the top of the gluing member with the release paper completely peeled off is black, and the top of the gluing member without the release paper peeled off is white; the second vision detection mechanism is located on one side of the second tape peeling mechanism 42 and on the side of the second tape peeling mechanism 42 along the transportation direction of the conveyor line 5, so as to facilitate the second vision detection mechanism to detect the adhesive member 91 with the top release paper peeled off located on the conveyor line 5; wherein, when the cell gluing device is started, after the release paper on the top of the adhesive member 91 pasted on the cell 92 is peeled off by the second tape peeling mechanism 42, the conveyor line 5 transports the cell 92 to the position where the second vision detection mechanism is located, so that the second vision detection mechanism detects whether the release paper on the top of the adhesive member 91 has been completely peeled off according to the color of the adhesive member 91. If the release paper on the top of the adhesive member 91 has been completely peeled off, then the conveyor line 5 continues to transport the cell 92 with the adhesive member 91 pasted thereon to the next process stage to realize the bonding and fixing of the cell 92 and the end plate through the adhesive member 91; if the release paper on the top of the adhesive member 91 has not been completely peeled off, the cell 92 with the adhesive member 91 pasted thereon is sent to the second defective product area by other mechanisms.

[0044] Therefore, in this embodiment, the top release paper of the adhesive member 91 is detected according to the second vision detection mechanism, thereby improving the product quality and ensuring that the adhesive member 91 can successfully connect the cell 92 and the end plate.

[0045] In one embodiment, refer to Figure 1 and Figure 4As shown, the battery cell gluing device further includes a battery cell positioning mechanism 7, which is located on one side of the conveyor line 5 and is used to position the battery cell 92 on the conveyor line 5. Specifically, during the movement of the battery cell 92 on the conveyor line 5, its position may change. Therefore, the battery cell gluing device further includes a battery cell positioning mechanism 7, which is located on one side of the conveyor line 5. When the battery cell gluing device is started, when the second transfer mechanism 32 sucks the adhesive part 91 after the bottom release paper is peeled off above the conveyor line 5, the battery cell positioning mechanism 7 moves towards the battery cell 92 on the conveyor line 5, so that the battery cell positioning mechanism 7 positions the battery cell 92 on the conveyor line 5, ensuring that the positions of the battery cell 92 and the adhesive part 91 are consistent. Then, the second transfer mechanism 32 presses down the adhesive part 91 onto the battery cell 92, finally realizing the sticking and fixing of the adhesive part 91 and the battery cell 92, so as to improve the accuracy of the second transfer mechanism 32 in sticking the adhesive part 91 on the battery cell 92, avoid the phenomenon of crooked sticking, and thus improve the product quality.

[0046] In a specific embodiment, referring to Figure 7 As shown, the battery cell positioning mechanism 7 includes a cylinder assembly 71 and a positioning assembly 72 for positioning the battery cell 92. The positioning assembly 72 is fixedly arranged on the side of the cylinder assembly 71 facing the battery cell 92, and the cylinder assembly 71 drives the positioning assembly 72 to perform telescopic movement towards or away from the battery cell 92. Specifically, the battery cell positioning mechanism 7 is used to position the battery cell 92 on the conveyor line 5 to improve the accuracy of sticking the adhesive part 91 on the battery cell 92. The battery cell positioning mechanism 7 includes a cylinder assembly 71 and a positioning assembly 72. The cylinder assembly 71 is used to drive the positioning assembly 72 so that the positioning assembly 72 can perform telescopic movement towards and away from the battery cell 92. The positioning assembly 72 is used to position the battery cell 92, that is, when the positioning assembly 72 contacts the battery cell 92 on the conveyor line 5, it can adjust and position the position of the battery cell 92. The positioning assembly 72 is fixedly arranged on the side of the cylinder assembly 71 facing the battery cell 92. Therefore, when the battery cell gluing device is started, the cylinder assembly 71 extends, driving the positioning assembly 72 to move towards the battery cell 92 on the conveyor line 5 until the positioning assembly 72 contacts the battery cell 92 and guides and positions the battery cell 92, so that the positions of the battery cell 92 and the adhesive part 91 sucked by the second transfer mechanism 32 are consistent. After the positioning of the battery cell 92 is completed, the second transfer mechanism 32 presses down the adhesive part 91 onto the battery cell 92, realizing the sticking and fixing of the adhesive part 91 and the battery cell 92, thereby improving the accuracy of sticking the adhesive part 91 on the battery cell 92 and improving the product quality.

[0047] More specifically, the parts of the positioning component 72 in contact with the battery cell 92 are made of insulating materials, so as to improve the structural stability between the positioning component 72 and the battery cell 92 and ensure that the battery cell 92 is not damaged by the positioning component 72.

[0048] In one embodiment, as shown in Figure 7 the positioning component 72 includes a flexible plate 721 and two flexible rollers 722. The flexible plate 721 extends along the width direction of the battery cell 92. One side of the flexible plate 721 is fixedly connected to the cylinder component 71, and the two flexible rollers 722 are respectively rotatably connected to both ends of the other side of the flexible plate 721. Specifically, the positioning component 72 includes a flexible plate 721 and two flexible rollers 722. The flexible plate 721 extends along the width direction of the battery cell 92, and the length of the flexible plate 721 is the same as the width of the battery cell 92, so that the flexible plate 721 can be in complete close contact with one side of the battery cell 92 in the width direction. One side of the flexible plate 721 is fixedly connected to the cylinder component 71, so that when the cylinder component 71 makes a telescopic movement, it can drive the flexible plate 721 to make a telescopic movement at the same time, so that the flexible plate 721 can guide and position the battery cell 92. The two flexible rollers 722 are respectively rotatably connected to both ends of the other side of the flexible plate 721, and the two flexible rollers 722 are perpendicularly connected to the flexible plate 721, so that the two flexible rollers 722 can be in close contact with both sides of the battery cell 92. That is, when the flexible plate 721 and the two flexible rollers 722 are in contact with the battery cell 92, the battery cell 92 is embedded in the space enclosed by the flexible plate 721 and the two flexible rollers 722. By pushing the flexible plate 721 and the two flexible rollers 722 to move along the length direction of the battery cell 92 by the cylinder component 71, the two flexible rollers 722 are in rolling connection with both sides of the battery cell 92, and the flexible plate 721 abuts against one side of the battery cell 92, so that under the guiding and pushing of the flexible plate 721 and the two flexible rollers 722, the battery cell 92 moves to a position corresponding to the adhesive member 91, and further makes the accuracy higher when the adhesive member 91 is pasted onto the battery cell 92, improving the product quality.

[0049] More specifically, as shown in Figure 7As shown, the conveyor line 5 is provided with a carrier 51. The four corners 511 of the carrier 51 are right-angle structures for abutting and positioning with the four corners of the battery cell 92. Specifically, the conveyor line 5 is used to convey the battery cell 92. The conveyor line 5 is provided with a carrier 51. The carrier 51 is used to place the battery cell 92, and the shape and size of the carrier 51 are consistent with those of the battery cell 92. The battery cell 92 is a rectangular structure, so the carrier 51 is also a rectangular structure. The four corners 511 of the carrier 51 are right-angle structures, that is, the four corners 511 of the carrier 51 are all "L" shapes. When the battery cell 92 is placed on the carrier 51, the four corners of the battery cell 92 abut and position with the four corners 511, thereby performing preliminary positioning on the battery cell 92 on the conveyor line 5. Then, the battery cell positioning mechanism 7 performs secondary positioning on the battery cell 92, greatly improving the accuracy of the position of the battery cell 92 and the adhesive part 91, improving the accuracy of pasting the adhesive part 91 on the battery cell 92, and thus improving the product quality.

[0050] In a specific embodiment, referring to Figure 1 As shown, the battery cell pasting device further includes a first waste box 81. The first waste box 81 is disposed adjacent to the first positioning mechanism 2 and is used to collect the release paper at the bottom of the adhesive part 91. Specifically, the battery cell pasting device further includes a first waste box 81. The first waste box 81 is used to collect the release paper at the bottom of the adhesive part 91. The first waste box 81 is located on one side of the first positioning mechanism 2 and is disposed adjacent to the first positioning mechanism 2, facilitating the first adhesive tearing mechanism 41 to throw the release paper at the bottom of the adhesive part 91 into the first waste box 81, thereby facilitating the collection of the release paper at the bottom of the adhesive part 91. Among them, when the battery cell pasting device is started, the first adhesive tearing mechanism 41 moves towards the first positioning mechanism 2 and clamps the release paper at the bottom of the adhesive part 91, then moves downward to tear off the release paper at the bottom of the adhesive part 91. After that, the first adhesive tearing mechanism 41 moves towards the direction of the first waste box 81 to tear the release paper and throws the release paper into the first waste box 81, thereby realizing the tearing and collection of the release paper at the bottom of the adhesive part 91, improving the cleanliness of the machine table. At the same time, the moving distance of the first adhesive tearing mechanism 41 is relatively short, saving energy consumption.

[0051] More specifically, the first waste box 81 includes a first guiding funnel and a first turnover box. The first guiding funnel is fixedly arranged at the upper end of the first turnover box, and the first guiding funnel is communicated with the first turnover box. Among them, the first adhesive tearing mechanism 41 throws the release paper at the bottom of the adhesive part 91 into the first guiding funnel from above the first guiding funnel, and the first guiding funnel guides the release paper into the first turnover box, thereby completing the collection of the release paper, improving the accuracy of collection and the convenience of cleaning the release paper.

[0052] In this embodiment, the first glue tearing mechanism 41 and the first waste box 81 are respectively located on both sides of the first positioning mechanism 2, and the first waste box 81 is arranged close to the conveying line 5.

[0053] In one embodiment, referring to Figure 1 and Figure 5 As shown, the battery cell gluing device further includes a second waste box 82. The second waste box 82 is located on one side of the conveying line 5 and is used to collect the release paper on the top of the glued part 91. Specifically, the battery cell gluing device further includes a second waste box 82. The second waste box 82 is used to collect the release paper on the top of the glued part 91. The second waste box 82 is located on one side of the conveying line 5 and is arranged adjacent to the conveying line 5, which facilitates the second glue tearing mechanism 42 to throw the release paper on the top of the glued part 91 into the second waste box 82, so as to facilitate the collection of the release paper on the top of the glued part 91. Among them, when the battery cell gluing device is started, the second glue tearing mechanism 42 moves towards the conveying line 5 and clamps the release paper on the top of the glued part 91, then moves upward to tear off the release paper on the top of the glued part 91.

Specifically, the loading mechanism 1 is used to store a plurality of the adhesive parts 91 and perform orderly feeding of the plurality of adhesive parts 91. The loading mechanism 1 includes a turntable 11 and a plurality of loading components 12. The loading components 12 are used to store a plurality of the adhesive parts 91, and the plurality of adhesive parts 91 are arranged in an orderly manner along the height direction of the loading components 12 within the device components. The loading components 12 are fixedly arranged on the turntable 11, and the plurality of loading components 12 are arranged at intervals as required on the turntable 11. The turntable 11 is used to rotate the plurality of loading components 12 so that after the adhesive parts 91 in the plurality of loading components 12 on one side are all loaded, directly through the rotation of the turntable 11, the plurality of loading components 12 on the other side that have not been loaded are rotated to the loading position where the first transfer mechanism 31 can suck the adhesive parts 91, realizing automatic feeding. Therefore, when manually feeding the adhesive parts 91 into the loading components 12, after manually placing a certain quantity into the plurality of loading components 12, placement can be carried out at intervals for a period of time, thereby reducing the use of labor and no longer requiring corresponding personnel to guard the feeding.

[0057] More specifically, referring to Figure 7 As shown, the turntable 11 includes a support base 111, a rotating component 112, and a turntable 113. The two ends of the rotating component 112 are respectively connected to the support base 111 and the turntable 113. The rotating component 112 is used to drive the turntable 113 to rotate. The upper surface of the turntable 113 is fixedly provided with multiple groups of the loading components 12. The support base 111 is used to support the rotating component 112 and the turntable 113.

[0058] In a specific embodiment, referring to Figure 6 and Figure 7As shown, the loading assembly 12 includes a plurality of fixed rods 121 and a base 122. The base 122 is fixedly connected to the turntable 11. The plurality of fixed rods 121 are respectively fixedly arranged on the turntable 11 at intervals along the circumferential direction of the base 122 and perpendicular to it. The base 122 and the plurality of fixed rods 121 enclose a storage cavity 123 for storing the adhesive member 91. Specifically, the loading assembly 12 includes a plurality of fixed rods 121 and a base 122. The base 122 is horizontally fixedly connected to the turntable 11. The plurality of fixed rods 121 are fixedly connected to the turntable 11 perpendicularly. The plurality of fixed rods 121 are arranged outside the base 122 and are spaced along the circumferential direction of the base 122, so that the plurality of fixed rods 121 and the base 122 together enclose a storage cavity 123 for storing the adhesive member 91. A plurality of the adhesive members 91 can be stored, and the plurality of adhesive members 91 can be stacked in sequence along the height direction of the fixed rod 121 in the storage cavity 123. The structure of the loading assembly 12 is simple and the production cost is low.

[0059] In one embodiment, referring to Figure 6 and Figure 7 As shown, the loading assembly 12 further includes a brush 124. The brush 124 is fixedly arranged at the top of the fixed rod 121 and faces the storage cavity 123, and is used to prevent the first transfer mechanism 31 from sucking multiple adhesive members 91 at one time. Specifically, the loading assembly 12 further includes a brush 124. The brush 124 is fixedly arranged at the top of the fixed rod 121. The top of the fixed rod 121 refers to the end of the fixed rod 121 away from the turntable 11, and the brush 124 faces the center of the storage cavity 123. When the first transfer mechanism 31 sucks the adhesive member 91 from above the loading assembly 12, during the process of the adhesive member 91 leaving the storage cavity 123, the brush 124 can generate a certain frictional resistance to the adhesive member 91. This frictional component can ensure that each time the first transfer mechanism 31 sucks the adhesive member 91 from the storage cavity 123, only one adhesive member 91 is sucked, and prevent the first transfer mechanism 31 from sucking out multiple adhesive members 91 at one time, thus affecting the production quality.

[0060] In a specific embodiment, referring to Figure 8As shown, the first adhesive tearing mechanism 41 and the second adhesive tearing mechanism 42 both include an adhesive tearing jaw 431, a jaw cylinder 432, a lifting assembly 433 and a moving assembly 434.

One end of the jaw cylinder 432 is fixedly connected to the lifting assembly 433, and the other end of the jaw cylinder 432 is fixedly connected to the adhesive tearing jaw 431. Among them, the moving assembly 434 drives the lifting assembly 433 to move in the horizontal direction of the machine table, and then drives the jaw cylinder 432 and the adhesive tearing jaw 431 to move in the horizontal direction of the machine table. The lifting assembly 433 drives the jaw cylinder 432 to move up and down in the vertical direction of the machine table, and then drives the adhesive tearing jaw 431 to move up and down in the vertical direction of the machine table. The jaw cylinder 432 is used to drive the adhesive tearing jaw 431 to perform a telescopic motion. The adhesive tearing jaw 431 is used to clamp the release paper at the top or bottom of the adhesive member 91. Thus, by driving the moving assembly 434, the lifting assembly 433 and the jaw cylinder 432, the adhesive tearing jaw 431 can tear off the release paper. The structures of the first adhesive tearing mechanism 41 and the second adhesive tearing mechanism 42 are simple and highly integrated, making full use of the space utilization rate of the machine table, avoiding waste of space, and at the same time, the operation of tearing off the release paper of the adhesive member 91 is more accurate.
