[0036] The present utility model will be further described in detail below in conjunction with specific embodiments.

[0037] Embodiment:

[0038] As Figure 1 shown, a full - automatic half - cell dicing machine 1 includes a loading unit 11, a dicing unit 12, and an unloading unit 13 arranged in sequence along the X direction.

[0039] As Figures 2 to 4As shown in the figure, the loading unit 11 includes a loading conveyor line 111 arranged along the X direction, two groups of loading racks 112 respectively arranged on both sides of the loading conveyor line 111 in the Y direction, and a loading transfer assembly 113 straddling above the loading racks 112 and the loading conveyor line 111 in the Y direction. On each loading rack 112, two loading bins 1121 are arranged side by side along the X direction, and a lifting mechanism 1122 is respectively located below the two loading bins 1121. On one side of each loading rack 112 facing away from the loading conveyor line 111, a safety light curtain 114 is provided. The loading transfer assembly 113 includes a first Y-direction moving module 1131, a loading arm 1132 driven by the first Y-direction moving module 1131, two loading lifting mechanisms 1133 arranged side by side along the X direction at the lower part of the loading arm 1132, and two loading suction heads 1134 respectively driven by the two loading lifting mechanisms 1133.

[0040] The operator places the whole stack of battery wafers 2 into the loading bin 1121 from the outside of the safety light curtain 114. The safety light curtain 114 can detect whether there is any foreign object entering the working area during operation and is used for warning. The two loading bins 1121 on the same loading rack 112 can feed materials synchronously. The specific working process is that the first Y-direction moving module 1131 drives the two loading suction heads 1134 to move above the loading bin 1121 on the same side, and the lifting mechanism 1122 jacks up the whole stack of battery wafers 2 already in the loading bin 1121, so that the topmost battery wafer 2 enters the height that the loading suction head 1134 can adsorb; the two loading lifting mechanisms 1133 respectively drive their own loading suction heads 1134 to lift and lower, and then suck two battery wafers 2 from the loading bin 1121. After the loading suction head 1134 rises, it carries the battery wafers 2 and translates above the loading conveyor line 111. The loading suction head 1134 places the two battery wafers 2 one after another on the loading conveyor line 111, and the loading conveyor line 111 will send the two battery wafers 2 to the scribing unit 12.

[0041] As Figures 5 to 8As shown, the dicing unit 12 includes a material taking conveyor line 121, two groups of dicing assemblies 122, a material discharging conveyor line 123, a material taking transfer assembly 124 and a material discharging transfer assembly 125. The material taking conveyor line 121, the two groups of dicing assemblies 122 and the material discharging conveyor line 123 are each conveyed along the X direction; the material taking conveyor line 121 is connected to the feeding conveyor line 111, the material taking conveyor line 121 is located between the inlet sections of the two groups of dicing assemblies 122, and the material taking transfer assembly 124 straddles above the inlet sections of the two groups of dicing assemblies 122 along the Y direction; the material discharging conveyor line 123 is located between the outlet sections of the two groups of dicing assemblies 122, and the material discharging transfer assembly 125 straddles above the outlet sections of the two groups of dicing assemblies 122 along the Y direction. The material taking transfer assembly 124 includes a second Y-direction moving module 1241 and two sets of material taking adsorption mechanisms 1242 driven by the second Y-direction moving module 1241 in a linkage manner. Each set of material taking adsorption mechanism 1242 includes a pair of material taking suction heads 12421 arranged side by side in the Y direction and a material taking air cylinder 12422 that respectively drives the lifting of the two material taking suction heads 12421. The material taking adsorption mechanism 1242 alternately places the paired battery cells 2 sent on the material taking conveyor line 121 onto the two groups of dicing assemblies 122. The material discharging transfer assembly 125 includes a third Y-direction moving module 1251 and two sets of material discharging adsorption mechanisms 1252 driven by the third Y-direction moving module 1251 in a linkage manner. Each set of material discharging adsorption mechanism 1252 includes a pair of material discharging suction heads 12521 and a separating air cylinder 12522 that drives the Y-direction spacing of the two material discharging suction heads 12521. The material discharging adsorption mechanism 1252 alternately places the paired half battery cells 21 sent out from the two groups of dicing assemblies 122 onto the material discharging conveyor line 123.

[0042] The second Y-direction moving module 1241 can move the left material-taking suction head above the discharging conveyor line 123. The left material-taking air cylinder drives the left material-taking suction head to descend to suck the battery slice 2. At the same time, the right material-taking suction head 12421 places the previously taken battery slice 2 onto the right scribing assembly. After the left material-taking suction head rises, the second Y-direction moving module 1241 then makes the left material-taking suction head translate above the left scribing assembly 122. After the left material-taking suction head descends, it places the battery slice 2 onto the left scribing assembly. At this time, the right material-taking suction head 12421 goes to the discharging conveyor line 123 to suck another delivered battery slice 2. The above process can be cycled to perform the edge-taking and material-taking of the battery slice 2. The material-taking and discharging actions of the discharging transfer assembly 125 are similar to those of the material-taking transfer assembly 124. The difference is that when the material-taking transfer assembly 124 sends the battery slice 2 to both sides, the discharging transfer assembly 125 sends the half battery 21 to the middle material-taking conveyor line 121. At the same time, the discharging transfer assembly 125 also uses the separation air cylinder 12522 to increase the distance between the two half batteries 21 separated from the same battery slice 2. After the scribing assembly divides the battery slice 2 into two equal-sized half batteries 21, the half batteries 21 move below the discharging transfer assembly 125. The discharging transfer assembly 125 also alternately places two pairs of half batteries 21 onto the discharging conveyor line 123. During the movement, the separation air cylinder 12522 can make the discharging suction head 12521 separate, and the distance between the two half batteries 21 becomes larger, which is more convenient for subsequent baking operations.

[0043] As Figure 5 and Figure 6 shown, the scribing assembly 122 includes a scribing conveyor line 1221, a position detection mechanism 1222, and a scribing mechanism 1223. The scribing conveyor line 1221 extends along the X direction and is successively divided into an entrance section 12211, a detection and adjustment section 12212, a scribing section 12213, and a separation and exit section 12214. The position detection mechanism 1222 is located above the detection section 12212. The scribing mechanism 1223 includes an induction head 12231 located above the Y-direction adjustment section 12213, a laser cutting head 12232 located on one side of the induction head 12231, a water-cooling spray head 12233 located on one side of the laser cutting head 12232, and a water receiving tank 12234 located below the scribing conveyor line 1221. A waste box 126 is also provided behind the separation and exit section 12214.

[0044] After the battery cell 2 is placed on the inlet section 12211, it continues to be conveyed in the X direction, stops below the position detection mechanism 1222 to detect the position of the battery cell 2, and the detection and adjustment section 12212 will adjust and center the battery cell 2 so that the centered position of the battery cell 2 is aligned with the laser cutting head 12232; when the induction head 12231 detects the battery cell 2, the laser cutting head 12232 starts to work, and during the movement of the battery cell 2, it is cut into two half cells 21. The water-cooled nozzle 12233 will continuously cool the half cells 21 at the same time, and the cooling water falls into the water receiving tank 12234 and flows away. If the position detection mechanism 1222 detects that the battery cell 2 has surface problems, then the battery cell 2 will directly fall into the waste box 126 for collection without being cut, so as not to flow to the subsequent baking part.

[0045] As Figure 9 shown, the blanking unit 13 includes an adsorption conveyor line 131 connecting the discharging conveyor line 123 and a first drying mechanism 132, a glue coating mechanism 133, a second drying mechanism 134, a visual inspection mechanism 135 and a defective product transfer assembly 136 arranged in sequence along the adsorption conveyor line 131. A waste discharge box 137 is also provided on one side of the outlet of the adsorption conveyor line 131. The defective product transfer assembly 136 includes a fourth Y-direction moving module 1361 and a pair of Y-direction side-by-side defective product transfer suction heads 1362 driven by the fourth Y-direction moving module 1361. The defective product transfer suction heads 1362 move the defective half cells 21 to the waste discharge box 137. The first drying mechanism 132 is located at the front section of the adsorption conveyor line 131, the glue coating mechanism 133 and the second drying mechanism 134 are located in the middle section of the adsorption conveyor line 131, and the visual inspection mechanism 135 and the defective product transfer assembly 136 are located at the rear section of the adsorption conveyor line 131.

[0046] Because the half cells 21 will be wetted when passing through the scribing mechanism 1223, the surface needs to be dried by the first drying mechanism 132 when outputting from the adsorption conveyor line 131. While keeping the adsorption conveyor line 131 sucking the lower surface of the half cells 21 tightly, a protective film is applied to the upper surface of the dry half cells 21 by the glue coating mechanism 133, and then the protective film is dried by the second drying mechanism 134. The fourth Y-direction moving module can drive the defective product transfer suction heads 1362 to move between the upper part of the adsorption conveyor line 131 and the upper part of the waste discharge box 138. After being detected by the visual inspection mechanism 135, the adsorption conveyor line 131 inputs the qualified products into the next device, and the unqualified products are adsorbed by the defective product transfer suction heads 1362 and placed into the waste discharge box 137. This device can adapt to the continuous manufacturing process, has high working efficiency and is safe in operation.

[0047] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
