Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a battery skirt bending mechanism and battery shaping equipment. Background Technology

[0002] For pouch batteries, after the cell manufacturing is completed, the cell usually needs to be heat-sealed into an aluminum-plastic film. The size of the aluminum-plastic film is larger than the size of the cell. Therefore, after the cell is heat-sealed, the edge area of ​​the aluminum-plastic film will adhere to form the skirt of the battery. In order to prevent the skirt from affecting subsequent processing, the skirt needs to be bent.

[0003] The prior art publication number is CN110202776A, entitled "A Processing System for Battery Skirt Processing," which discloses a skirt bending device. The device includes a first bending assembly, comprising a first bending member, a second bending member, and a third bending member. One end of the first bending member has a first pressing surface; one end of the second bending member has a second pressing surface, which, together with the first pressing surface, forms a clamping space to clamp and fix the skirt within the clamping space. The first end of the skirt extends through the clamping space. The third bending member applies a force different from the direction of extension to the first end of the skirt, causing the first end of the skirt to bend relative to the rest of the skirt, forming a first bent portion. By using the first and second bending members to clamp the skirt, and by applying a tangential force to the side of the skirt extending beyond the clamping space using the third bending member, clear and distinct creases can be generated on the skirt corresponding to the edge area of ​​the clamping space, thereby improving the consistency of the creases.

[0004] Existing skirt bending equipment has three sets of bending components, but it can only complete one bending action, essentially performing a right-angle bend. After bending, the skirt is completely attached to the battery body. This method can be used to bend multiple non-tab skirts outside the battery body, but for skirts with tabs, the bent tabs cannot be attached to the battery body and need to be extended outwards. Therefore, after the above equipment performs one bend, other equipment is needed to perform a second bend on the tabs, which cannot meet the bending requirements in one go.

[0005] Furthermore, since the aluminum-plastic film is bonded to the entire battery body, multiple sides need to be bent during actual bending. When bending one side, due to the relatively soft nature of the aluminum-plastic film, the already bent edges on both sides of the bending surface will bend outwards under stress, affecting the bending effect of the edges on other sides.

[0006] In actual use, in order to prevent the bent skirt from deforming and to ensure the overall structural strength of the battery, it is also necessary to reshape and fix the bent skirt.

[0007] In summary, based on actual usage requirements, there is a need to provide a battery skirt bending mechanism and a battery shaping device for shaping and fixing the bent skirt. Summary of the Invention

[0008] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the bending equipment in the prior art cannot meet the bending requirements of the skirt with tabs, and cannot shape and fix the skirt after bending. The present invention provides a battery skirt bending mechanism and a battery shaping device. The bending mechanism can complete two bending requirements in one bending action. On the other hand, when bending one side, it can close and limit the other sides to ensure the bending quality. The battery shaping device applies glue to the skirt after bending to fix the position of the skirt and enhance the overall strength of the battery.

[0009] To solve the above technical problems, the present invention provides a battery skirt bending mechanism, characterized in that it includes:

[0010] A fixture for carrying a battery, the battery comprising: a battery body and a skirt protruding from the battery body;

[0011] A pressure plate assembly is provided corresponding to the fixture, and the pressure plate assembly presses and fixes the battery body onto the fixture.

[0012] A lifting assembly is disposed below the fixture, and the lifting assembly pushes the skirt from below the fixture to bend it once toward the battery body;

[0013] A pressing component is disposed above the fixture, corresponding to the lifting component. The pressing component pushes the skirt, which has been bent once, from above the fixture and bends it a second time away from the battery body, so that the skirt has a fitting part that fits against the side of the battery body and a bent part that protrudes from the fitting part. A height difference is formed between the bent part and the bottom surface of the battery body.

[0014] Side-pressure components are disposed on both sides of the fixture, and the side-pressure components clamp the skirt edges that protrude from both sides of the battery body after secondary bending from both sides of the fixture.

[0015] In one embodiment of the present invention, both the pressure plate assembly and the lower pressure assembly are disposed above the fixture, the pressure plate assembly and the lower pressure assembly are mounted on the same fixed plate, and the pressure plate assembly and the lower pressure assembly are respectively mounted on two sides of the fixed plate, wherein:

[0016] The pressure plate assembly includes: a pressure block and a pressure block drive source connected to the pressure block. The pressure block drive source drives the pressure block to move towards or away from the battery body. The pressure block contacts the battery body and presses and fixes the battery body onto the fixture.

[0017] The pressing assembly includes a pressing head and a pressing drive source connected to the pressing head. The pressing drive source drives the pressing head to move towards or away from the skirt. The pressing head abuts against the skirt. The pressing drive source is a lead screw drive structure and can drive the pressing head to a set position.

[0018] In one embodiment of the present invention, both the lifting assembly and the side-pressing assembly are disposed below the fixture, and the lifting assembly and the side-pressing assembly are mounted on the same support frame, wherein:

[0019] The lifting assembly includes: a lifting block and a lifting drive source connected to the lifting block. The lifting drive source drives the lifting block to move towards or away from the skirt. The lifting block abuts against the skirt. The lifting drive source is a lead screw drive structure and can drive the lower lifting block to a set position. A pressure detection sensor is provided between the lifting block and the lifting drive source.

[0020] The side pressure assembly includes: a side pressure drive source, two sliders driven by the side pressure drive source, a side pressure block slidably disposed on each of the sliders, and an elastic element disposed between the side pressure block and the slider. The side pressure drive source drives the sliders to move towards each other, and the side pressure block abuts against the elastic element and squeezes the side skirt, thereby clamping the side skirt onto the battery body by the elastic force of the elastic element.

[0021] In one embodiment of the present invention, it further includes: a transfer assembly, the transfer assembly including a horizontal transfer module, a lifting transfer module and a bracket, the horizontal transfer module being connected to the bracket, the horizontal transfer module driving the bracket to move toward or away from the fixture, the pressure plate assembly, lifting assembly, lowering assembly, side pressing assembly and lifting transfer module being disposed on the bracket, and the lifting transfer module being connected to the support frame.

[0022] In one embodiment of the present invention, a positioning component is further included, the positioning component being disposed on the bracket, the positioning component comprising: a positioning camera disposed above the fixture and a light source disposed below the fixture, the positioning component being capable of detecting the horizontal position and vertical height of the battery body on the fixture, and the movement position of the bracket in the transfer component being controlled by the detection of the positioning component.

[0023] To address the aforementioned technical problems, the present invention also provides a battery shaping device, comprising:

[0024] A turntable is provided with a loading station, a bending station, a dispensing station and a unloading station. The fixture is set on the turntable, and the turntable drives the fixture to pass through the loading station, the bending station, the dispensing station and the unloading station in sequence.

[0025] A battery skirt bending mechanism is provided on the outside of the turntable, corresponding to the bending station.

[0026] A dispensing mechanism is located on the outside of the turntable, corresponding to the dispensing station. The dispensing mechanism performs dispensing between the battery body and the bent skirt.

[0027] In one embodiment of the present invention, the dispensing mechanism includes:

[0028] Dispensing drive source;

[0029] A dispensing gun is connected to the dispensing drive source and is driven by the dispensing drive source to move along a set dispensing path.

[0030] A dispensing positioning camera is used to take pictures and locate the dispensing position, generate a dispensing image, and plan the dispensing route based on the dispensing image.

[0031] The glue cleaning component is used to wipe and clean the nozzle of the glue gun;

[0032] Waste glue buckets are used to collect glue residue after application.

[0033] In one embodiment of the present invention, a limiting mechanism is further provided on the loading station. The limiting mechanism is correspondingly provided with the fixture. The limiting mechanism includes a limiting block that matches the shape of the battery body and a blocking drive source. The blocking drive source drives the limiting block to limit and fix the battery body on the fixture.

[0034] In one embodiment of the present invention, a pre-inspection station and a re-inspection station are respectively provided before and after the dispensing station around the turntable, and both the pre-inspection station and the re-inspection station include a laser vision inspection mechanism.

[0035] The laser vision inspection mechanism set up at the pre-inspection station inspects the position of the bent skirt and battery body to determine the bending effect.

[0036] The laser vision inspection mechanism installed at the pre-inspection station and the re-inspection station can also detect the thickness of the dispensing position before and after dispensing, calculate the dispensing amount based on the thickness change, and detect the dispensing shape to match the dispensing route set before dispensing and judge the dispensing effect.

[0037] In one embodiment of the present invention, a loading and transport channel and a loading and unloading device are provided outside the loading station; a qualified product transport channel, a non-compliant product transport channel, and a loading and unloading device are provided outside the unloading station.

[0038] The technical solution of the present invention has the following advantages compared with the prior art:

[0039] The battery skirt bending mechanism of this invention, with the cooperation of a pressure plate assembly and a fixture, can fix the position of the battery body and prevent the battery body from shifting during bending, thus affecting the bending effect. Because the position of the battery body is fixed, when the lifting assembly pushes the skirt from below the fixture, the skirt can bend towards the battery body once. By controlling the position of the lifting assembly to not completely exceed the battery body, the skirt can be tilted relative to the battery body without completely adhering to it. At this time, the pressing assembly pushes the tilted skirt, which has been bent once, from above the fixture, bending it a second time away from the battery body. Through the cooperation of the pressing assembly and the lifting assembly, the skirt has a fitting part that fits against the side of the battery body and a bent part that protrudes from the fitting part. The tab is located at the bent part, protruding from the battery body and forming a height difference with the bottom surface of the battery body. Thus, the bending mechanism can complete the two bending requirements of the skirt with tabs in one bending action.

[0040] In actual bending, the skirts protruding from the battery body need to be bent. When bending one of the sides, due to the softness of the aluminum-plastic film, the skirts that have already been bent on both sides of the bending surface will bend outward under force, affecting the bending effect of the skirts on other sides. To solve this problem, the battery skirt bending mechanism of the present invention is also provided with side pressure components, which are set on both sides of the fixture. The side pressure components clamp and gather the skirts that protrude from both sides of the battery body after the second bending from both sides of the fixture, preventing the skirts on both sides of the bending surface from being squeezed and curling outward, thus ensuring the overall bending quality of the battery skirts.

[0041] The battery shaping equipment of the present invention includes the aforementioned battery skirt bending mechanism and adhesive dispensing mechanism. After the skirt is bent by the battery skirt bending mechanism, the adhesive dispensing mechanism applies adhesive between the battery body and the bent skirt to fix the position of the skirt and enhance the overall strength of the battery.

[0054] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0055] Example 1

[0056] Reference Figure 1 As shown, this invention discloses a battery skirt bending mechanism, comprising: a fixture 210, a pressure plate assembly 220, a lifting assembly 230, a pressing assembly 240, and a side pressing assembly 250, wherein:

[0057] The fixture 210 is used to support the battery. In this embodiment, the battery includes a battery body and a skirt protruding from the battery body. Since the skirt of the battery needs to be stamped and bent, the fixture 210 is provided with a contour groove 211 to accommodate the battery. The contour groove 211 is a semi-closed structure. The skirt of the battery can protrude from the contour groove 211 to facilitate subsequent stamping and bending.

[0058] The pressure plate assembly 220 is correspondingly arranged with the fixture 210. The pressure plate assembly 220 applies pressure to the fixture 210. The pressure plate and the fixture 210 clamp the battery body from the upper and lower sides, which can fix the battery body on the fixture 210 and prevent the battery body from shifting during bending and affecting the bending effect.

[0059] The lifting component 230 is located below the fixture 210. The lifting component 230 pushes the skirt from below the fixture 210. Because the pressure plate component 220 fixes the position of the battery body, when the lifting component 230 pushes the skirt from below the fixture 210, the skirt can bend once towards the battery body. This controls the lifting position of the lifting component 230 to not completely exceed the battery body, so that the skirt can be tilted relative to the battery body and will not be completely attached to the battery body.

[0060] The pressing component 240 and the lifting component 230 are respectively disposed above the fixture 210. The pressing component 240 pushes the skirt after one bend from above the fixture 210 to bend it a second time away from the battery body. By pressing the skirt together with the lifting component 230, the skirt has a fitting part that fits against the side of the battery body and a bent part that protrudes from the fitting part. The tab is located at the bent part, which can protrude from the battery body and form a height difference with the bottom surface of the battery body. Thus, the bending mechanism can complete the two bending requirements of the skirt with tab in one bending action.

[0061] In actual bending, the skirt edges protruding from the battery body need to be bent. When bending one of the surfaces, due to the softness of the aluminum-plastic film, the already bent skirt edges on both sides of the bending surface will bend outward under force, affecting the bending effect of the skirt edges on other surfaces. To solve this problem, the battery skirt bending mechanism of the present invention is also provided with a side pressure component 250, which is set on both sides of the fixture 210. The side pressure component 250 clamps and gathers the skirt edges protruding from both sides of the battery body after the second bending from both sides of the fixture 210, preventing the skirt edges on both sides of the bending surface from being squeezed and curling outward, thus ensuring the overall bending quality of the battery skirt edges.

[0062] Reference Figure 2 As shown, in this embodiment, since both the pressure plate assembly 220 and the pressing assembly 240 are disposed above the fixture 210, they are mounted on the same fixed plate. Since the pressure plate assembly 220 and the pressing assembly 240 apply pressure to the battery body and the skirt respectively, they are mounted on opposite sides of the fixed plate.

[0063] The pressure plate assembly 220 includes a pressure block 221 and a pressure block drive source 222 connected to the pressure block 221. The pressure block drive source 222 drives the pressure block 221 to move towards or away from the battery body. The pressure block 221 contacts the battery body and presses and fixes the battery body onto the fixture 210. In this embodiment, the pressure plate assembly 220 only needs to apply a certain amount of pressure to the battery body; therefore, it is not necessary to precisely control the movement position of the pressure block 221. The pressure block drive source 222 is a cylinder drive component, which can drive the pressure block 221 to move. However, when setting the pressure block 221, it needs to act on the battery body. Since the battery is a flammable and explosive product, the pressure cannot be too high to prevent damage to the battery. Therefore, an elastic connector is set between the pressure block 221 and the pressure block drive source 222 so that the pressure block 221 can elastically clamp the battery body. The elastic force provides an appropriate amount of pressure, which can ensure that the battery body is clamped and fixed without damaging the battery due to excessive pressure.

[0064] The pressing assembly 240 includes a pressing head 241 and a pressing drive source 242 connected to the pressing head 241. The pressing drive source 242 drives the pressing head 241 to move towards or away from the skirt. The pressing head 241 abuts against the skirt. In this embodiment, according to design requirements, it is necessary to limit the height between the bent part of the skirt after bending and the bottom surface of the battery body. It is necessary to precisely limit the bending position, that is, it is necessary to limit the movement position of the pressing head 241. Therefore, the pressing drive source 242 is set as a lead screw drive structure. The lead screw drive structure can precisely control the pressing head 241 to move to any position and stop, so that the pressing drive source 242 can drive the pressing head 241 to move to the set position.

[0065] Reference Figure 3 As shown, in this embodiment, since both the lifting assembly 230 and the side-pressing assembly 250 are located below the fixture 210, the lifting assembly 230 and the side-pressing assembly 250 can be mounted on the same support frame, wherein:

[0066] The lifting assembly 230 includes a lifting block 231 and a lifting drive source 232 connected to the lifting block 231. The lifting drive source 232 drives the lifting block 231 to move towards or away from the skirt. The lifting block 231 abuts against the skirt. In this embodiment, according to design requirements, it is necessary to limit the height between the bent part of the skirt and the bottom surface of the battery body. The bending position needs to be precisely defined, that is, the moving position of the lifting block 231 needs to be limited. Therefore, the downward drive source 242 is also a screw drive structure. The screw drive structure can precisely control the lifting block 231 to move to any position and stop, thereby enabling the lifting drive... The power source 232 can drive the lifting block 231 to move to a set position. In this embodiment, the lifting block 231 and the pressing block 221 are configured to cooperate to clamp and press the skirt to deform it. In order to ensure that the skirt can be bent and deformed in place, a certain clamping force needs to be set between the lifting block 231 and the pressing block 221. If the clamping force is too small, the bending process cannot be achieved. If the clamping force is too large, it is easy to cause stamping damage. Therefore, in this embodiment, a pressure detection sensor is also set between the lifting block 231 and the lifting drive source 232. The stamping force can be preset and the stamping force can be adjusted by real-time monitoring and feedback through the pressure detection sensor.

[0067] The side-pressure assembly 250 includes: a side-pressure drive source 251, two sliders 252 driven by the side-pressure drive source 251, a side-pressure block 253 slidably disposed on each of the sliders 252, and an elastic element 254 disposed between the side-pressure block 253 and the slider 252. The side-pressure assembly 250 directly clamps and fixes the skirt to the battery body, which is essentially a clamping action on the battery body. Since the battery is a flammable and explosive material, the clamping force cannot be too large to prevent damage to the battery. Therefore, the side-pressure drive source 251 drives the sliders 252 to move towards each other, and the side-pressure block 253 abuts against and squeezes the elastic element 254 with the skirt. The elastic force of the elastic element 254 clamps the skirt to the battery body. The elastic force provides an appropriate amount of pressure to ensure the clamping and fixing of the battery body without damaging the battery due to excessive pressure.

[0068] In this embodiment, the position of the fixture 210 is relatively fixed during the bending process. The fixture 210 can be transported to the bending mechanism of the present invention via a turntable or conveyor belt. Therefore, when setting up the bending mechanism, it is necessary for the bending mechanism to avoid the fixture 210 during transportation. After the fixture 210 is transported to the position, the bending mechanism can move relative to the fixture 210, so that the pressure plate assembly 220 moves to the top of the battery body, the lifting assembly 230 and the pressing assembly 240 move to the upper and lower sides of the skirt respectively, and the side pressing mechanism moves to the horizontal sides of the fixture 210.

[0069] Reference Figure 1 In order to meet the movement requirements of the bending mechanism, refer to Figure 1 As shown, the bending mechanism of the present invention further includes a transfer component 260, which can drive the pressure plate component 220, the lifting component 230, the pressing component 240, and the side pressing component 250 to move as a whole. In order to ensure the accuracy of the moving position, the bending mechanism of the present invention also includes a positioning component 270. The positioning component 270 first detects the moving position of the fixture 210, and determines the moving route of the transfer component 260 based on the relative position of the battery body on the fixture 210 and the bending mechanism. The transfer component 260 drives the pressure plate component 220, the lifting component 230, the pressing component 240, and the side pressing component 250 to move as a whole to the designated position, thereby realizing the stamping and bending of the skirt.

[0070] Reference Figure 4As shown, the transfer assembly 260 includes a horizontal transfer module 261, a lifting transfer module 262, and a support 263. The horizontal transfer module 261 is connected to the support 263. The horizontal transfer module 261 drives the support 263 to move closer to or further away from the fixture 210. The pressure plate assembly 220, lifting assembly 230, lowering assembly 240, side pressing assembly 250, and lifting transfer module 262 are all mounted on the support 263. The horizontal transfer module 261 can drive the pressure plate assembly 220, lifting assembly 230, lowering assembly 240, and side pressing assembly 250 to move to the upper and lower sides corresponding to the fixture 210, respectively, to adjust the horizontal position before bending. The lifting transfer module 262 is connected to the support frame. The lifting module can adjust the height of the lifting assembly 230 and the side pressing assembly 250 to adjust the vertical position before bending.

[0071] Reference Figure 5 As shown, the positioning component 270 is disposed on the bracket 263. The positioning component 270 includes a positioning camera 271 disposed above the fixture 210 and a light source 272 disposed below the fixture 210. In this embodiment, a photographic positioning method is adopted. The positioning component 270 can detect the horizontal position and vertical height of the battery body on the fixture 210. The detection by the positioning component 270 can control the movement position of the bracket 263 in the transfer component 260.

[0072] Example 2

[0073] Based on the above embodiment 1, and according to actual usage, in order to prevent deformation of the bent skirt and ensure the overall structural strength of the battery, it is also necessary to reshape and fix the bent skirt, referring to... Figure 6 As shown, this embodiment also discloses a battery shaping device, including: a turntable 100, a battery skirt bending mechanism 200, and a dispensing mechanism 300. The turntable 100 is provided with a loading station, a bending station, a dispensing station, and an unloading station. A fixture 210 is mounted on the turntable 100. The turntable 100 drives the fixture 210 to sequentially pass through the loading station, bending station, dispensing station, and unloading station. The battery skirt bending mechanism 200 and the dispensing mechanism 300 are respectively located on the outer side of the turntable 100, corresponding to the bending station and the dispensing station. After the skirt is bent by the battery skirt bending mechanism 200, the dispensing mechanism 300 applies adhesive between the battery body and the bent skirt, thereby fixing the position of the skirt and strengthening the overall strength of the battery.

[0074] Reference Figure 7As shown, the number of fixtures 210 on the turntable 100 is set according to the number of workstations. Each workstation can independently and simultaneously complete the processing action with different fixtures 210, thereby improving processing efficiency. The fixtures 210 are set on the edge of the turntable 100. An opening for the skirt to protrude is provided in the contour groove 211 of the fixture 210, which facilitates docking with different mechanisms at different workstations. The turntable 100 drives the fixtures 210 to rotate. In order to prevent the battery body from moving relative to the fixtures 210 or detaching from the fixtures 210 under the action of centrifugal force, a suction cup 212 is provided on the fixtures 210 to achieve adsorption and fixation of the battery body.

[0075] Specifically, the fixture 210 needs to rotate and stop at different workstations sequentially under the drive of the turntable 100, and rotate again after processing is completed. In order to ensure the accuracy of the stopping position of the fixture 210 each time the turntable 100 rotates, in addition to ensuring that there is a battery body in the fixture 210, a battery detection mechanism 400 is also provided below each turntable 100. The battery detection mechanism 400 is a photoelectric detection sensor, which can detect whether the fixture 210 has moved into place and whether the fixture 210 carries a battery body. Only when both of the above requirements are met at the same time will the mechanism set at the corresponding workstation start to work.

[0076] Specifically, since the battery body is attached by a suction cup, its position relative to the fixture 210 will not change during the rotation of the turntable 100. Therefore, it is sufficient to ensure that the battery body is accurately placed in the fixture 210 at the loading station. In this embodiment, a limiting mechanism 500 is also provided at the loading station, and the limiting mechanism 500 is correspondingly provided to the fixture 210. Figure 8 As shown, the limiting mechanism 500 includes a limiting block 510 that matches the shape of the battery body and a block driving source 520. The block driving source 520 drives the limiting block 510 to limit and fix the battery body on the fixture 210.

[0077] Reference Figure 9 As shown, in this embodiment, in order to perform dispensing at a designated location according to design requirements, the dispensing mechanism 300 includes: a dispensing drive source 310, a dispensing gun 320, a dispensing positioning camera 330, a glue cleaning assembly 340, and a waste glue bin 350. The dispensing drive source 310 is a three-axis transfer drive source, connected to the dispensing gun 320. The dispensing gun 320 moves along a predetermined dispensing path driven by the dispensing drive source 310. The dispensing positioning camera 330 takes pictures of the dispensing location, generates a dispensing image, and plans the dispensing path based on the image.

[0078] Specifically, in this embodiment, AB glue is used for dispensing. Before dispensing, the dispensing head needs to be wiped. Therefore, a glue cleaning component 340 is set to wipe and clean the gun head of the dispensing gun 320. The glue cleaning component 340 includes: a feed roller, a take-up roller and a glue cleaning belt. The wiping action of the glue cleaning belt on the gun head is achieved by the rotation of the feed roller and the take-up roller.

[0079] Specifically, in this embodiment, it is also necessary to clean the waste glue in the glue gun 320, so a waste glue bucket 350 is set up to collect the glue after dispensing.

[0080] To ensure product quality, it is necessary to inspect the quality of bending and dispensing. Around the turntable 100, refer to... Figure 1 As shown, in this embodiment, a pre-inspection station and a re-inspection station are respectively provided before and after the dispensing station. A pre-inspection mechanism and a re-inspection mechanism are respectively provided outside the pre-inspection station and the re-inspection station, as shown in the figure. Figure 10 As shown, both the pre-inspection mechanism and the re-inspection mechanism are equipped with a laser vision inspection mechanism 600. The laser vision inspection mechanism 600 includes a vision inspection sensor 610 and a sensor platform 620 that drives the vision inspection sensor to move.

[0081] The laser vision inspection mechanism 600 set at the pre-inspection station inspects the position of the bent skirt and battery body to determine the bending effect.

[0082] The laser vision inspection mechanism 600 installed at the pre-inspection station and the re-inspection station can also detect the thickness of the dispensing position before and after dispensing, calculate the dispensing amount based on the thickness change, and detect the dispensing shape to match the dispensing route set before dispensing and judge the dispensing effect.

[0083] Specifically, in this embodiment, in order to realize the loading and unloading of the battery body on the turntable 100, a loading and transport channel and a loading and unloading device are set outside the loading station. The loading and transport channel is set to realize the batch transportation of materials. The loading and unloading device grabs the materials on the loading and transport channel and places the materials in the fixture 210.

[0084] Similarly, a qualified product conveying channel, an NG product conveying channel, and a material handling device are set outside the unloading station. Based on the test results, it is determined whether the product is qualified or NG. The material handling device picks up the product from the fixture 210 and places it into the qualified product conveying channel and the NG product conveying channel respectively according to the test results. In this embodiment, NG products include four situations: incorrect barcode scanning, poor clamping, poor glue dispensing, and poor re-inspection.

[0085] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
