[0056] The present application is described in detail below through specific embodiments:

[0057] See also Figure 1 and Figure 2The embodiment of the present application provides a battery cell glue printing device 100, which includes a first rotating disk 110, a first feeding mechanism 120, a glue printing mechanism 130, a feeding mechanism 150, a flipping mechanism 140 and a second feeding mechanism 160, wherein the first rotating disk 110 has a plurality of first stations 111, some of the first stations 111 are used to pick up battery cells without glue printing, and another part of the first stations 111 are used to pick up battery cells with single-sided glue printing; the first feeding mechanism 120 is located upstream of the first rotating disk 110, and the first feeding mechanism 120 is used to feed battery cells without glue printing to the first rotating disk 110; the glue printing mechanism 130 is provided The glue printing mechanism 130 is arranged downstream of the first turntable 110, and is used for printing glue on either side of the surface of the unprinted battery cell or printing glue on the unprinted surface of the battery cell with single-sided glue printing; the unloading mechanism 150 is arranged downstream of the glue printing mechanism 130, and is used for unloading the battery cell with double-sided glue printing; the flipping mechanism 140 is arranged downstream of the glue printing mechanism 130, and is used for flipping the battery cell with single-sided glue printing so that the unprinted surface of the battery cell with single-sided glue printing faces upward; the second feeding mechanism 160 is arranged downstream of the flipping mechanism 140, and is used for feeding the battery cell with single-sided glue printing flipped by the flipping mechanism 140 to the first turntable 110.

[0058] The above-mentioned multiple first workstations 111 refer to two or more first workstations 111 , for example, two first workstations 111 , four first workstations 111 , and the like.

[0059] In the present embodiment, when printing glue on both sides of the battery cell, first, the first rotating disk 110 on the first loading mechanism 120 loads the battery cell without glue printing. When the battery cell without glue printing is set at the first station 111 on the first rotating disk 110, the first rotating disk 110 rotates and drives the battery cell without glue printing to move to the glue printing mechanism 130, so that the glue printing mechanism 130 prints glue on any side surface of the battery cell without glue printing (i.e., the upper surface of the battery cell) to form a battery cell with glue printing on one side. Then, the flipping mechanism 140 flips the battery cell with glue printing on one side so that the unprinted surface of the battery cell with glue printing on one side (if the glue is printed on the upper surface of the battery cell, the unprinted surface of the battery cell with glue printing on one side is the lower surface of the battery cell) faces upward, that is, the placement state of the battery cell with glue printing on one side is adjusted to facilitate the continued glue printing of the glue printing mechanism 130. Then, After being flipped by the flipping mechanism 140, the battery cell with single-sided glue printing is fed by the second feeding mechanism 160 to other first stations 111 on the first turntable 110. Similarly, through the rotation of the first turntable 110, the battery cell with single-sided glue printing can be transferred to the glue printing mechanism 130, so that the glue printing mechanism 130 prints glue on the unprinted surface of the battery cell with single-sided glue printing to form a battery cell with double-sided glue printing. After the double-sided glue printing of the battery cell is completed, the battery cell with double-sided glue printing is unloaded by the unloading mechanism 150. It can be seen that in this embodiment, through the cooperation of the first turntables 110 and the flipping mechanism 140 of multiple first stations 111, one battery cell glue printing device 100 can be set to achieve double-sided glue printing of the battery cell. Compared with setting two battery cell glue printing devices 100 to print glue on both sides of the battery cell, the production cost of the battery cell is reduced.

[0060] In addition, by setting up a plurality of first turntables 110 of the first workstations 111 to separately transport the battery cells without glue printing and the battery cells with glue printing on one side, on the one hand, it is possible to avoid confusion between the battery cells without glue printing and the battery cells with glue printing on one side, thereby facilitating the independent transportation of the battery cells without glue printing and the battery cells with glue printing on one side. On the other hand, compared with setting up two independent conveying devices to separately transport the battery cells without glue printing and the battery cells with glue printing on one side, the structure of the battery cell glue printing device 100 is simplified.

[0061] In some possible embodiments, see Figure 2 and Figure 3 The first turntable 110 can rotate around the geometric center axis of the first turntable 110, and the multiple first stations 111 include a first sub-station 1111, a second sub-station 1112, a third sub-station 1113 and a fourth sub-station 1114 which are arranged in sequence along the geometric center axis of the first turntable 110. The first sub-station 1111 and the third sub-station 1113 are used to pick up battery cells without glue printing, and the second sub-station 1112 and the fourth sub-station 1114 are used to pick up battery cells with glue printing on one side.

[0062] The geometric center axis of the first turntable 110 is Figure 2 The position indicated by the dotted line a1.

[0063] Since the first turntable 110 can rotate around the geometric center axis of the first turntable 110, the first sub-station 1111, the second sub-station 1112, the third sub-station 1113 and the fourth sub-station 1114 are arranged around the geometric center axis of the first turntable 110, and the first sub-station 1111 and the third sub-station 1113 are used to pick up the battery cells without glue printing, and the second sub-station 1112 and the fourth sub-station 1114 are used to pick up the battery cells with single-sided glue printing. Therefore, when the first sub-station 1111 releases the battery cells without glue printing to the glue printing mechanism 130, the first loading mechanism 120 can load the third sub-station 1113 so that the third sub-station 1113 picks up the battery cells without glue printing. The second sub-station 1112 and the fourth sub-station 1114 are the same as the first sub-station 1111 and the third sub-station 1113, thereby improving the glue printing efficiency of the battery cells.

[0064] Of course, in actual operation, optional, see Figure 3 First, the first rotating disk 110 rotates clockwise around its geometric center axis (i.e. Figure 3 The first turntable 110 is rotated 90° in the direction indicated by the arrow x1 in the figure, so that the first sub-station 1111 releases the unprinted battery cells to the printing mechanism, and the third sub-station 1113 picks up the unprinted battery cells loaded by the first loading mechanism 120. After the first sub-station 1111 releases the unprinted battery cells and the third sub-station 1113 picks up the unprinted battery cells, the first turntable 110 is further rotated 90° in the clockwise direction around its geometric center axis. At this time, the fourth sub-station 1113 1114 releases the battery cells with single-sided printing to the printing mechanism, and at the same time the second sub-station 1112 picks up the battery cells with single-sided printing loaded by the second loading mechanism 160. After the fourth sub-station 1114 releases the battery cells with single-sided printing and the second sub-station 1112 picks up the battery cells with single-sided printing, the first turntable 110 continues to rotate 90° clockwise around its geometric center axis. This cycle is repeated to transfer the battery cells without printing and the battery cells with single-sided printing.

[0065] In some possible embodiments, see Figure 2 and Figure 3The first turntable 110 can be raised and lowered in the vertical direction. The first turntable 110 has a bottom surface and a top surface in the vertical direction. The first sub-station 1111, the second sub-station 1112, the third sub-station 1113 and the fourth sub-station 1114 are all located on the bottom surface. The first sub-station 1111, the second sub-station 1112, the third sub-station 1113 and the fourth sub-station 1114 are all provided with vacuum adsorption holes, so that the first sub-station 1111 and the third sub-station 1113 can adsorb the unprinted battery cells loaded by the first loading mechanism 120, and the second sub-station 1112 and the fourth sub-station 1114 can adsorb the single-sided printed battery cells loaded by the second loading mechanism 160.

[0066] The vertical direction refers to Figure 2 The direction indicated by the arrow y1.

[0067] Since the first substation 1111, the second substation 1112, the third substation 1113 and the fourth substation 1114 are all located on the bottom surface, and the first substation 1111, the second substation 1112, the third substation 1113 and the fourth substation 1114 are all provided with vacuum adsorption holes, when the first loading mechanism 120 loads the battery cell without glue printing, the first substation 1111 and the third substation 1113 can adsorb and fix the upper surface of the battery cell without glue printing and As the first turntable 110 rotates, it moves. When it is at the glue printing station, the vacuum in the vacuum adsorption hole on the first sub-station 1111 or the third sub-station 1113 is released, so that the battery cell adsorbed by the first sub-station 1111 or the third sub-station 1113 without glue printing is printed by the glue printing mechanism 130 at the glue printing station to form a battery cell with glue printed on one side. When the second feeding mechanism 160 feeds the battery cell with glue printed on one side, the second sub-station 1112 and the fourth sub-station 1113 are pressed. 4 can adsorb and fix the unprinted surface of the battery cell with single-sided printing and move with the rotation of the first rotary disk 110. When at the printing station, by releasing the vacuum in the vacuum adsorption holes on the second sub-station 1112 or the fourth sub-station 1114, the unprinted surface of the battery cell with single-sided printing adsorbed by the second sub-station 1112 or the fourth sub-station 1114 is printed with glue by the printing mechanism 130 at the printing station to form a battery cell with double-sided printing. It can be seen that compared with the first The sub-station 1111, the second sub-station 1112, the third sub-station 1113 and the fourth sub-station 1114 are all arranged on the top surface, reducing the setting of the loading and transferring mechanism such as the robot, thereby simplifying the structural design of the battery cell printing device 100, and at the same time reducing the difficulty of loading the unprinted battery cells to the first sub-station 1111 and the third sub-station 1113, and reducing the difficulty of loading the single-sided printed battery cells to the second sub-station 1112 and the fourth sub-station 1114.

[0068] It should be noted that vacuum adsorption holes are provided on the first sub-station 1111, the second sub-station 1112, the third sub-station 1113 and the fourth sub-station 1114. It can be understood that the vacuum adsorption holes are directly provided on the bottom surface, or a vacuum adsorption nozzle is provided on the bottom surface, and the vacuum adsorption holes are located in the vacuum adsorption nozzle.

[0069] Of course, the specific method for the first sub-station 1111 and the third sub-station 1113 to pick up the unprinted battery cells, and the second sub-station 1112 and the fourth sub-station 1114 to pick up the single-sided printed battery cells is not limited to the above-mentioned vacuum adsorption fixation, and the unprinted battery cells or the single-sided printed battery cells can also be picked up in a clamping manner by setting a clamping claw structure.

[0070] In some possible embodiments, see Figure 4 The flipping mechanism 140 includes a support frame 141 and a flipping frame 142 arranged on the support frame 141. The flipping frame 142 includes a first bearing portion 1421, a connecting portion 1422 and a second bearing portion 1423 connected in sequence. The first bearing portion 1421 has a first adsorption surface 14211, and the second bearing portion 1423 has a second adsorption surface 14231. The first adsorption surface 14211 and the second adsorption surface 14231 are respectively located on opposite sides of the flipping frame 142. The first adsorption surface 14211 and the second adsorption surface 14231 are both used for adsorbing battery cells with single-sided printing. The flipping frame 142 has a loading station 142a and a unloading station 142b. The connecting portion 1422 is rotatably connected to the support frame 141 so that the first adsorption surface 14211 and the second adsorption surface 14231 can be switched between the loading station 142a and the unloading station 142b respectively.

[0071] Based on the structure in the above embodiment, after the printing mechanism 130 prints glue on one side of the unprinted battery cell to form a battery cell with single-sided printing, the battery cell with single-sided printing is moved to the flip mechanism 140. At this time, if the first adsorption surface 14211 is located at the loading station 142a (for example, the first adsorption surface 14211 faces upward), then the second adsorption surface 14231 is located at the unloading station 142b (the second adsorption surface 14231 faces downward), and the battery cell with single-sided printing is loaded onto the first adsorption surface 14211. Then, the connecting portion 1422 is rotated relative to the support frame 141, so that the first adsorption surface 14211 is flipped to the unloading station 142b to unload the battery cell with single-sided printing, so as to facilitate the first rotation. The second station 181 or the fourth station on the tray 110 picks up the battery. At this time, the second adsorption surface 14231 is flipped to the loading station 142a for loading. In other words, by flipping the flip frame 142 relative to the support frame 141, the battery cell with single-sided glue printing can be flipped 180°. It can be seen that by flipping the flip frame 142 relative to the support frame 141, the battery cell with single-sided glue printing can be flipped so that the unprinted surface of the battery cell with single-sided glue printing faces upward, which is convenient for the glue printing of the glue printing mechanism 130. In this way, only one glue printing mechanism 130 needs to be set at the glue printing station to realize double-sided glue printing of the battery cell. Compared with setting two glue printing mechanisms 130 to print glue on two surfaces of the battery cell respectively, the production cost of the battery cell is further reduced.

[0072] In addition, optionally, vacuum adsorption holes are provided on the first adsorption surface 14211 and the second adsorption surface 14231. When the vacuum adsorption holes are in a vacuum state or close to a vacuum state, the battery cell with single-sided adhesive printing can be adsorbed and fixed. When the vacuum in the vacuum adsorption holes is released, the vacuum adsorption holes can release the adsorbed battery cell with single-sided adhesive printing.

[0073] In some possible embodiments, see Figure 5 The second loading mechanism 160 includes a movable supporting platform 161, which can reciprocate between the flip mechanism 140 and the first turntable 110. The supporting platform 161 is located below the flip frame 142 and is used to support the battery cell with single-sided glue printing released by the first adsorption surface 14211 or the second adsorption surface 14231.

[0074] Specifically, the glue printing mechanism 130 prints glue on the upward surface of the battery cell without glue printing to form a battery cell with glue printing on one side. When the battery cell with glue printing on one side reaches the flipping mechanism 140, the surface with glue printing is still facing upward until it is flipped by the flipping mechanism 140. That is to say, when the battery cell with glue printing on one side is flipped from the loading station 142a to the unloading station 142b by the flipping mechanism 140, the surface of the battery cell with glue printing on one side without glue printing faces upward.

[0075] In this embodiment, since the carrying platform 161 is located below the flip frame 142, and the carrying platform 161 can move between the flip mechanism 140 and the first turntable 110, when the battery cell with single-sided printing is located at the unloading station 142b after the flip frame 142 is flipped, the surface of the battery cell with single-sided printing is facing upward. At this time, if the flip frame 142 releases the battery cell with single-sided printing at the unloading station 142b, the battery cell will fall on the carrying platform 161 with the surface of the battery cell with no printing facing upward. 61 moves toward the first turntable 110 to transport the battery cell with single-sided printing to the first return tray, so that the second sub-station 1112 or the fourth sub-station 1114 on the first turntable 110 can pick up the battery cell with single-sided printing. After being transported by the first turntable 110, the unprinted surface can be printed with glue at the glue printing mechanism 130. It can be seen that the flipped battery cell with single-sided printing can be transported to the first turntable 110 without the need for additional devices such as manipulators, and the structure is simple and easy to operate.

[0076] In addition, the movement of the support platform 161 between the turning mechanism 140 and the first turntable 110 can be achieved by manual operation or by automatic control system control.

[0077] In some possible embodiments, the second loading mechanism 160 further includes a correction mechanism connected to the carrier 161 , and the correction mechanism is used to correct the carrier 161 so that the battery cell with single-sided printing on the carrier 161 is adapted to the first station 111 .

[0078] Specifically, the correction mechanism includes a visual detector, a controller electrically connected to the visual detector, and a driving machine electrically connected to the controller. First, the visual detector detects whether the battery cell with single-sided printing on the support platform 161 is located at a preset position. If the visual detector detects that part of the battery cell with single-sided printing exceeds the preset position, the controller controls the driving machine to move the support platform 161 until the battery cell with single-sided printing is in the preset position. In this way, when the battery cell with single-sided printing is loaded on the second sub-station 1112 or the fourth sub-station 1114 of the first turntable, the loading accuracy can be improved, and at the same time, the stability of the battery cell with single-sided printing fixed on the second sub-station 1112 or the fourth sub-station 1114 is ensured.

[0079] In addition, the battery cells with single-sided printing on the above-mentioned supporting platform 161 are adapted to the first station 111. It should be understood that when the supporting platform 161 moves to the first turntable 110, the battery cells with single-sided printing on the supporting platform 161 are aligned with the second sub-station 1112 or the fourth sub-station 1114, so that the second sub-station 1112 or the fourth sub-station 1114 can accurately pick up the battery cells with single-sided printing on the supporting platform 161. If the second sub-station 1112 and the fourth sub-station 1114 are both provided with vacuum adsorption holes for adsorbing the battery cells with single-sided printing, the vacuum adsorption holes can be completely covered by the battery cells with single-sided printing, thereby ensuring the stability of vacuum adsorption.

[0080] In some possible embodiments, see Figure 6 The battery cell printing device 100 also includes a conveying mechanism 170 and a second turntable 180, wherein the conveying mechanism 170 is used to convey the battery cell with single-sided printing after the printing mechanism 130 to the flipping mechanism 140 or to convey the battery cell with double-sided printing after the printing mechanism 130 to the feeding mechanism 150; the second turntable 180 has a plurality of second workstations 181, and the plurality of second workstations 181 are used to pick up the battery cell with single-sided printing or the battery cell with double-sided printing after the printing mechanism 130 respectively, and transfer them to the conveying mechanism 170.

[0081] The conveying mechanism 170 includes but is not limited to a conveying belt, a conveying roller, and the like.

[0082] In addition, the plurality of second workstations 181 refers to two or more second workstations 181 .

[0083] Based on the structure in the present embodiment, when the printing mechanism 130 completes printing on the unprinted battery cells or the battery cells with single-sided printing, the second turntable 180 first picks up the battery cells with single-sided printing or the battery cells with double-sided printing after printing, and transfers the battery cells with single-sided printing or the battery cells with double-sided printing to the conveying mechanism 170 by rotating the second turntable 180, and then the conveying mechanism 170 conveys them separately. It can be seen that by providing the second turntable 180 and making the second turntable 180 have a plurality of second stations 181, when one of the second stations 181 unloads the battery cells with single-sided printing or the battery cells with double-sided printing to the conveying mechanism 170, another second station 181 can load the battery cells with single-sided printing or the battery cells with double-sided printing on the printing mechanism 130, thereby improving the printing efficiency of the printing mechanism 130 and the conveying efficiency of the conveying mechanism 170.

[0084] In some possible embodiments, see Figure 6The conveying mechanism 170 includes a first conveying mechanism 171, a second conveying mechanism 172 and a return transport mechanism 173, wherein the first conveying mechanism 171 is used to convey the battery cells with double-sided printing to the feeding mechanism 150; the second conveying mechanism 172 is used to convey the battery cells with single-sided printing printed by the printing mechanism 130 to the flipping mechanism 140; the return transport mechanism 173 is located between the first conveying mechanism 171 and the second conveying mechanism 172, and is used to transport the battery cells with single-sided printing on the first conveying mechanism 171 to the second conveying mechanism 172.

[0085] Thus, the first conveying mechanism 171 , the second conveying mechanism 172 and the return conveying mechanism 173 can respectively convey the double-sided printed battery cells to the unloading mechanism 150 and convey the single-sided printed battery cells to the flipping mechanism 140 .

[0086] In addition, optionally, the first conveying mechanism 171 is a conveying roller, the second conveying mechanism 172 is a conveying belt, and the return transport mechanism 173 is arranged above the conveying roller and the conveying belt, and can absorb the battery cell with single-sided printing on the conveying roller to the conveying belt.

[0087] In some possible embodiments, see Figure 6 The conveying directions of the first conveying mechanism 171 and the second conveying mechanism 172 are opposite, and the first conveying mechanism 171 and the second conveying mechanism 172 are spaced apart perpendicular to the conveying direction; the battery cell printing device 100 also includes a rotating mechanism 193 arranged between the first conveying mechanism 171 and the second conveying mechanism 172, and the rotating mechanism 193 is used to rotate the battery cell with single-sided printing carried by the return conveying mechanism 173 from the first conveying mechanism 171, so that the battery cell with single-sided printing carried by the return conveying mechanism 173 from the rotating mechanism 193 to the second conveying mechanism 172 is adapted to the first workstation 111.

[0088] The conveying direction of the first conveying mechanism 171 is Figure 6 The direction indicated by the arrow z2 in the figure is the direction of the second conveying mechanism 172. Figure 6 The direction indicated by the arrow z1 in the figure is perpendicular to the transmission direction. Figure 6 The direction is indicated by the Y arrow.

[0089] Since the conveying directions of the first conveying mechanism 171 and the second conveying mechanism 172 are opposite, and the battery cell is usually a rectangular structure, if the length side of the battery cell with single-sided printing transferred from the first conveying mechanism 171 is perpendicular to the conveying direction, then when it is directly transferred to the second conveying mechanism 172 through the return transfer mechanism 173, the length side of the battery cell with single-sided printing is still perpendicular to the conveying direction. However, this will cause the battery cell with single-sided printing loaded at the second sub-station 1112 or the fourth sub-station 1114 to be at odds with the second sub-station 1112 and the fourth sub-station 1114. The adsorption surfaces of the first and second sub-stations 1114 do not correspond, which affects the stability of the single-sided printed battery cells fixed on the second sub-station 1112 and the fourth sub-station 1114. Based on this, a rotating mechanism 193 is set between the first conveying mechanism 171 and the second conveying mechanism 172. The rotating mechanism 193 can rotate the battery cells placed on the second conveying mechanism 172 by a preset angle (such as rotating 90°, that is, the length side of the single-sided printed battery cells on the first conveying mechanism 171 is perpendicular to the length side of the single-sided printed battery cells on the second conveying mechanism 172).

[0090] Specifically, the flipping mechanism 140 includes a rotating table and a driving machine connected to the rotating table. The rotating table is used to place the battery cell with single-sided glue printing. The driving machine can drive the rotating table to rotate 90° in a clockwise or counterclockwise direction so that the direction of the length side and the direction of the width side of the battery cell with single-sided glue printing are switched with each other. That is to say, after the rotating table rotates, the original length direction of the battery cell with single-sided glue printing placed on the rotating table is switched to the width direction of the battery cell with single-sided glue printing.

[0091] In some possible embodiments, the cell printing device 100 further includes a first detection mechanism, which is disposed downstream of the second turntable 180 and is used to detect whether the cell transferred from the second turntable 180 to the first conveying mechanism 171 is a cell with single-sided printing.

[0092] The first detection mechanism includes but is not limited to a CCD detection machine, an infrared detector, and the like.

[0093] Based on the present embodiment, after the printing mechanism 130 completes printing, the second turntable 180 picks up the battery cells with single-sided printing or double-sided printing after printing and as the second turntable 180 rotates, the battery cells with single-sided printing and the battery cells with double-sided printing can be placed on the first conveying mechanism 171. In order to facilitate the control of the return transport mechanism 173 to accurately transport the battery cells with single-sided printing to the second conveying mechanism 172, the first detection mechanism detects the battery cells on the first conveying mechanism 171. If it is detected that the battery cells transported are battery cells with single-sided printing, the return transport mechanism 173 can be controlled to transport the battery cells with single-sided printing to the second conveying mechanism 172. Otherwise, the first conveying mechanism 171 continues to transport them to the unloading mechanism 150.

[0094] Therefore, by providing the first detection mechanism, the battery cells with single-sided printing on the first conveying mechanism 171 can be timely and accurately identified, further improving the efficiency of the battery cell printing device 100 in printing double-sided printing on the battery cells.

[0095] In some possible embodiments, see Figure 6 The battery cell printing device 100 also includes a second detection mechanism and a defective product recovery mechanism 191. The second detection mechanism is arranged between the first turntable 110 and the first feeding mechanism 120, and is used to detect whether the unprinted battery cells fed by the first feeding mechanism 120 have defects; the defective product recovery mechanism 191 is used to recover defective unprinted battery cells.

[0096] The second detection mechanism includes but is not limited to a CMOS camera, a CCD camera, etc.

[0097] Therefore, before the first loading mechanism 120 feeds the first turntable 110, the unprinted battery cells are inspected by the second inspection mechanism. If the unprinted battery cells have defects such as fragments, hidden cracks, etc., the defective product recovery mechanism 191 is controlled to recover them. Otherwise, the first return disk is fed, thereby improving the yield rate of battery cell production.

[0098] In some possible embodiments, the battery cell printing device 100 further includes a correction mechanism 192 , which is disposed upstream of the unloading mechanism 150 and is used to adjust the position of the battery cell with double-sided printing.

[0099] For example, the correction mechanism 192 includes a detector and a carrier, the carrier is used to carry the battery cell with double-sided printing, and the detector is used to detect whether the battery cell with double-sided printing on the carrier is located at a preset position. If it deviates from the preset position, the carrier needs to be controlled to adjust until the battery cell with double-sided printing is located at the preset position. At this time, the battery cell with double-sided printing can be transferred to the unloading mechanism 150 to ensure the unloading effect of the battery cell with double-sided printing.

[0100] It can be seen that by providing a correction mechanism, the effect of double-sided printed battery cell unloading can be improved.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
