Detailed implementation manners

[0021] To make the content of the present invention more clearly understood, the following further detailed description of the present invention is made according to the specific implementation manners in combination with the accompanying drawings.

[0022] See Figures 1 to 7 , the embodiment of the present application provides a full-automatic workpiece detection device, which includes a battery loading mechanism 100 and a first detection mechanism 200. Among them, the battery loading mechanism 100 is used to convey the battery to be detected to the first detection mechanism 200 located in the detection station. The first detection mechanism 200 drives the battery to be detected to enter multiple detection areas in sequence to realize the detection of different items of the battery to be detected.

[0023] Specifically, the battery loading mechanism 100 includes a tray loading and unloading assembly 110, a tray conveying assembly 120, and a first battery handling assembly 130.

[0024] Among them, the tray loading and unloading assembly 110 includes a first bin 111 and a second bin 112. The first bin 111 is used to place a full tray containing batteries to be detected, and the second bin 112 is used to place an empty tray without batteries. The internal structures of the first bin 111 and the second bin 112 are basically the same. Taking the first bin 111 as an example, it includes a bin frame, a tray lifting assembly arranged in the bin frame, and a feeding conveying assembly. The tray lifting assembly is used to drive the tray stack to lift, and it includes a lifting platform and a platform lifting drive device for driving the lifting platform to lift. The feeding conveying assembly is used to convey the tray stack to the lifting platform, and it includes a belt conveying assembly extending in the horizontal direction. The operator places the tray stack containing batteries to be detected on the belt conveying assembly, and then the belt conveying assembly conveys the tray stack to directly above the lifting platform. Subsequently, the platform lifting drive device drives the lifting platform to rise, which can drive the tray stack to rise to the loading station of the tray conveying assembly 120.

[0025] It can be understood that since the first bin 111 belongs to the tray loading station and the second bin 112 belongs to the tray unloading station, the operating logics of the first bin 111 and the second bin 112 are opposite.

[0026] Preferably, in order to adapt to trays of different sizes, a changeover adjustment assembly for adjusting the width of the bin frame is also provided in the first bin 111 and the second bin 112. Specifically, the two sides of the bin frame are two relatively arranged limiting side plates, and this changeover adjustment assembly is used to drive one of the limiting side plates to approach or move away from the other limiting side plate, so as to realize the adjustment of the width of the bin frame.

[0027] The tray conveying assembly 120 includes a first conveying guide rail 121, which is erected above the first bin 111 and the second bin 112 and extends along the arrangement direction of the first bin 111 and the second bin 112. One end of the first conveying guide rail 121 is directly above the second bin 112, and the other end extends to the loading station of the first battery handling assembly 130. The first conveying guide rail 121 includes two relatively arranged side plates, so that an opening communicating with the upper ends of the first bin 111 and the second bin 112 is formed at its bottom. A tray placement seat 122 is slidably arranged on the first conveying guide rail 121, and the tray placement seat 122 reciprocates along the first conveying guide rail 121 under the drive of a translation drive device arranged on the first conveying guide rail 121. A first tray handling assembly 123 and a second tray handling assembly 124 are fixedly arranged on one side of the first conveying guide rail 121.

[0028] Among them, the first tray handling component 123 includes a tray handling frame 123a fixedly installed directly above the first bin 111, a first lifting drive unit 123b fixedly installed on the tray handling frame 123a, and a first tray suction unit 123c drivingly connected to the first lifting drive unit 123b. When the tray lifting component in the first bin 111 drives the tray stack to rise to a preset height, the first lifting drive unit 123b drives the first tray suction unit 123c to descend until the first tray suction unit 123c sucks the uppermost tray in the tray stack. Subsequently, the first lifting drive unit 123b drives the first tray suction unit 123c to rise, and in cooperation with the left - right sliding of the tray placement seat 122 on the first conveying guide rail 121, places the full - tray on the tray placement seat 122.

[0029] The second tray handling component 124 includes a fourth conveying guide rail 124a fixedly arranged on one side of the second bin 112, and the fourth conveying guide rail 124a is erected above the second bin 112. A third sliding seat 124b is slidably installed on the fourth conveying guide rail 124a, and the third sliding seat 124b is driven by a translation drive device arranged on the fourth conveying guide rail 124a. A fourth lifting drive unit 124c is fixedly installed on the third sliding seat 124b, and the fourth lifting drive unit 124c is drivingly connected to the second tray suction unit 124b. When all the batteries in the tray on the tray placement seat 122 are taken out, the tray placement seat 122 drives the tray to move to the loading station of the second tray suction unit 124b, and then the second tray handling component 124 transports the empty tray into the second bin 112.

[0030] The first battery handling component 130 includes a second conveying guide rail 131 fixedly erected above the first conveying guide rail 121, and the extending direction of the second conveying guide rail 131 is perpendicular to the extending direction of the first conveying guide rail 121. One end of the second conveying guide rail 131 extends above the first conveying guide rail 121, and the other end extends to the detection station. A first sliding seat 132 is slidably arranged on the second conveying guide rail 131, and the first sliding seat 132 is driven by a translation drive device arranged on the second conveying guide rail 131. A first translation guide rail 133 is fixedly installed on the first sliding seat 132, the first translation guide rail 133 is parallel to the horizontal plane, and its extending direction is perpendicular to the extending direction of the second conveying guide rail 131. A first translation seat 134 is slidably arranged on the first translation guide rail 133, a second lifting drive unit 135 is fixedly arranged on the first translation seat 134, and the second lifting drive unit 135 is drivingly connected to the first lifting seat. A first rotation drive unit 136 is fixedly installed on the first lifting seat, and the first rotation drive unit 136 is drivingly connected to the first battery suction unit 137.

[0031] After the tray containing the battery to be detected moves to the loading station of the first battery handling component 130 along with the tray placement seat 122, the second lifting drive unit 135 drives the first lifting seat to lift, driving the first battery adsorption unit 137 to move towards the tray. Then, the first battery adsorption unit 137 adsorbs and removes the batteries to be detected in the tray one by one, and transports them to the detection station by the first battery handling component 130.

[0032] Preferably, two tray placement seats 122 are slidably arranged on the first conveying guide rail 121. These two tray placement seats 122 are located in horizontal planes at different heights, and the height difference between them is greater than the thickness of the tray. When all the batteries in the tray on one tray placement seat 122 are taken out, this tray placement seat 122 immediately moves to the loading station of the second tray handling component 124, and at the same time, the other tray placement seat 122 drives the full tray to move to the loading station of the first battery handling component 130, realizing uninterrupted loading of the first battery handling component 130, and the two tray placement seats 122 do not affect each other, improving work efficiency.

[0033] Furthermore, two sets of the first battery handling components 130 are provided, and the second conveying guide rails 131 in the two sets of the first battery handling components 130 are arranged in sequence along the extension direction of the first conveying guide rail 121. The two sets of the first battery handling components 130 alternately take out the batteries to be detected from the tray and transport them to the detection station, further improving the work efficiency of battery detection.

[0034] In addition, a limiting member for limiting and fixing the tray is provided on each tray placement seat 122.

[0035] The battery loading mechanism 100 further includes a battery transfer component 140 arranged between the first battery handling component 130 and the first detection mechanism 200. The battery transfer component 140 includes a third rotating seat 141 and four third battery fixing seats 142 fixedly arranged on the third rotating seat 141. These four third battery fixing seats 142 are evenly distributed on the same circumference, and the center of this circumference is located on the rotation axis of the third rotating seat 141. A third suction cup assembly 143 for adsorbing the battery to be detected is provided on each third battery fixing seat 142. After the first battery handling component 130 takes out the battery to be detected from the tray, the third rotating seat 141 rotates a certain angle, rotating the third suction cup assembly 143 without an adsorbed battery to the unloading station of the first battery handling component 130, facilitating the first battery handling component 130 to place the battery to be detected on the battery transfer component 140. After the battery transfer component 140 receives the battery to be detected, it controls the third rotating seat 141 to rotate and transfers the battery to be detected into the first detection mechanism 200.

[0036] It should be noted that a first CCD camera for positioning the battery to be detected is also provided between the first battery handling assembly 130 and the battery transfer assembly 140. During the process of the first battery handling assembly 130 driving the battery to move, the first CCD camera is located directly below a certain position in the battery displacement path. The first CCD camera can collect the position and angle of the battery, realize pick-up positioning, and adjust the placement position and angle of the battery based on the collected position information, so as to accurately place the battery to be detected on the third suction cup assembly 143.

[0037] In addition, before the battery to be detected is placed on the third suction cup assembly 143, the lower tab of the battery needs to be detected by a second CCD camera provided on one side of the battery transfer assembly 140. The second CCD camera uses a hemispherical light source to supplement light to the battery, and during the detection process, the second CCD camera will take two pictures, one with higher brightness and the other with lower brightness, and a total of two pictures will be output.

[0038] The first detection mechanism 200 includes a first rotating base 210, four first battery fixing bases 220 fixedly arranged on the first rotating base 210, and two first detection units 230. Among them, the first rotating base 210 is located on one side of the third rotating base 141. The four first battery fixing bases 220 are evenly distributed on the same circumference, and the center of the circle of this circumference is located on the rotation axis of the first rotating base 210. Each first battery fixing base 220 includes a first suction cup assembly 221 for adsorbing the battery to be detected and a suction cup lifting drive device 222 for driving the first suction cup assembly 221 to lift and lower.

[0039] It should be noted that during the rotation of the first rotating base 210 and the third rotating base 141, the annular displacement paths generated by any one of the third battery fixing bases 142 and any one of the first battery fixing bases 220 coincide at a certain position, and when one of the third battery fixing bases 142 is aligned with one of the first battery fixing bases 220, the corresponding third suction cup assembly 143 and the first suction cup assembly 221 are arranged opposite to each other, and the first suction cup assembly 221 is located directly above the third suction cup assembly 143. At this time, by driving the first suction cup assembly 221 to move downward through the suction cup lifting drive device 222, the battery to be detected adsorbed on the third suction cup assembly 143 can be transferred to the first suction cup assembly 221.

[0040] Two first detection units 230 are respectively fixedly arranged in a first detection area and a second detection area below the first rotating base 210. After the battery to be detected is transferred to one of the first suction cup assemblies 221, the first rotating base 210 rotates to drive the first suction cup assembly 221 to perform a circular motion. The first suction cup assembly 221 will drive the battery to be detected to pass through the first detection area and the second detection area in sequence. When each first suction cup assembly 221 drives the battery to be detected into the first detection area, the first detection unit 230 in the first detection area will perform the first bottom detection on the battery. After that, when the first suction cup assembly 221 drives the battery to be detected into the second detection area, the second detection unit 330 in the second detection area performs the second bottom detection on the battery. After the second bottom detection is completed, the first rotating base 210 drives the battery to continue to move and moves to the blanking station of the first detection mechanism 200.

[0041] A second detection mechanism 300 is further arranged on one side of the first detection mechanism 200. The second detection mechanism 300 includes a second rotating base 310, twelve second battery fixing seats 320 fixedly installed on the second rotating base 310, and a plurality of second detection units 330. Among them, the twelve second battery fixing seats 320 are evenly arranged on the same circumference, and the center of the circle is located on the rotation axis of the second rotating base 310. A second suction cup assembly 321 for adsorbing the battery to be detected is arranged on each second battery fixing seat 320. The plurality of second detection units 330 are respectively arranged on the side and above of the second rotating base 310, and when the second rotating base 310 rotates, any one of the second battery fixing seats 320 will pass through the detection areas of all the second detection units 330 in sequence.

[0042] In this embodiment, eight second detection units 330 are provided. Among them, two second detection units 330 are both used to detect the upper surface of the battery, two second detection units 330 are both used to detect the long side of the positive electrode side of the battery, two second detection units 330 are both used to detect the long side of the negative electrode side of the battery, and the remaining two second detection units 330 are respectively used to detect the non-tab side of the battery and the upper tab of the battery.

[0043] It should be noted that during the rotation of the first rotating seat 210 and the second rotating seat 310, the annular displacement paths generated by any one of the first battery fixing seats 220 and any one of the second battery fixing seats 320 coincide at a certain position. And when one of the first battery fixing seats 220 is aligned with one of the second battery fixing seats 320, the corresponding first suction cup assembly 221 and the second suction cup assembly 321 are arranged oppositely, and the first suction cup assembly 221 is directly above the second suction cup assembly 321. At this time, by driving the first suction cup assembly 221 to move downward through the suction cup lifting driving device 222, the battery to be detected adsorbed on the first suction cup assembly 221 can be transferred to the second suction cup assembly 321, so that the battery to be detected is automatically transferred from the first detection mechanism 200 to the second detection mechanism 300.

[0044] In addition, the full-automatic workpiece detection device provided by the embodiment of the present application further includes a battery blanking mechanism 400 for conveying the battery that has completed all detection items to the blanking station. The battery blanking mechanism 400 includes a second battery handling assembly 410, a battery conveying assembly 420, and a battery blanking assembly 430.

[0045] Among them, the second battery handling assembly 410 includes a third conveying guide rail 411 installed on one side of the second rotating seat 310. Two second sliding seats 412 are slidably arranged on the third conveying guide rail 411. A third lifting driving unit 413 is fixedly arranged on each second sliding seat 412, and each third lifting driving unit 413 is drivingly connected to a second battery adsorption unit 414. When the battery completes all item detections in the second detection mechanism 300, it will rotate to the loading station of the second battery adsorption unit 414. At this time, by driving the second battery adsorption unit 414 to move downward through the third lifting driving unit 413 and adsorbing the battery, the battery in the second detection mechanism 300 can be transferred to the second battery handling assembly 410, and then by sliding the second sliding seat 412 along the third conveying guide rail 411, the battery can be conveyed to the blanking station of the second battery handling assembly 410.

[0046] The battery conveying assembly 420 includes a first battery conveying guide rail 421 for conveying finished batteries, a second battery conveying guide rail 422 for conveying defective batteries, a battery handling manipulator 423 for moving the finished batteries on the first battery conveying guide rail 421 to the trays in the third bin 431, and a defective battery handling assembly 424 for conveying the defective batteries on the second battery conveying guide rail 422 to the trays in the fourth bin 431. Both the first conveying guide rail 121 and the second conveying guide rail 131 are arranged perpendicular to the third conveying guide rail 411, and the first battery conveying guide rail 421 and the second battery conveying guide rail 422 are arranged in sequence along the extending direction of the third conveying guide rail 411. One ends of both the first battery conveying guide rail 421 and the second battery conveying guide rail 422 extend to directly below the displacement path of the second battery adsorption unit 414, and the other ends of both the first battery conveying guide rail 421 and the second battery conveying guide rail 422 extend to the battery blanking assembly 430.

[0047] After all items of the battery are detected, the system can determine whether each battery is a genuine battery or a defective battery. Then, when the second battery handling assembly 410 handles the batteries, it can place the genuine batteries on the first battery conveying guide rail 421 and the defective batteries on the second battery conveying guide rail 422.

[0048] The battery blanking assembly 430 includes a third bin 431 and a fourth bin 431. Among them, the third bin 431 is used to place trays filled with finished batteries that have passed the inspection, and the fourth bin 431 is used to place trays filled with defective batteries that have not passed the inspection. One end of the first battery conveying guide rail 421 away from the third conveying guide rail 411 extends to one side of the third bin 431, and one end of the second battery conveying guide rail 422 away from the third conveying guide rail 411 extends to one side of the fourth bin 431.

[0049] It should be noted that the internal structures of the third bin 431 and the second bin 112 are basically the same as those of the first bin 111 and the second bin 112, and both include a bin rack, a tray lifting assembly arranged in the bin rack, a feeding conveying assembly, and a die change adjustment assembly for adjusting the width of the bin rack. After the trays in the third bin 431 are filled with batteries, they are stacked in sequence and gradually move downward, and after the full trays form a stack, the feeding conveying assembly conveys them out of the bin, and finally manual blanking is carried out.

[0050] Preferably, the second bin 112, the third bin 431, and the fourth bin 431 are arranged in sequence along the extending direction of the fourth conveying guide rail 124a, and the trays in the second bin 112, the third bin 431, and the fourth bin 431 are all located directly below the displacement path of the second tray adsorption unit 124b.

[0051] It can be understood that the second bin 112 is used to store empty trays, and the third bin 431 and the fourth bin 431 are located on one side of the second bin 112. The second tray handling assembly 124 can move the empty trays in the second bin 112 to the third bin 431 and the fourth bin 431 to hold the finished batteries and defective batteries after inspection. This not only eliminates the operation of manually adding trays in the third bin 431 and the fourth bin 431, but also has a shorter displacement path for the empty trays, further improving the working efficiency of battery inspection.

[0052] In this embodiment, the defective battery handling assembly 424 includes a fifth conveying rail 424a fixedly arranged on one side of the second battery conveying rail 422, a fourth sliding seat 424b slidably arranged on the fifth conveying rail 424a, a second translation rail 424c fixedly arranged on the fourth sliding seat 424b, a second translation seat 424d slidably arranged on the second translation rail 424c, a fifth lifting drive unit 424e fixedly arranged on the second translation seat 424d, a second lifting seat 424f drivingly connected to the fifth lifting drive unit 424e, a second rotation drive unit 424g fixedly installed on the second lifting seat 424f, and a third battery adsorption unit 424h drivingly connected to the second rotation drive unit 424g. Among them, the extending direction of the fifth conveying rail 424a is parallel to the extending direction of the second battery conveying rail 422. The second translation rail 424c is parallel to the horizontal plane, and its extending direction is perpendicular to the extending direction of the fifth conveying rail 424a. By moving the fourth sliding seat 424b along the fifth conveying rail 424a and the second translation seat 424d along the second translation rail 424c, the third battery adsorption unit 424h can be driven to move in the horizontal plane to align it with the batteries on the second battery conveying rail 422, and then driven by the fifth lifting drive unit 424e to adsorb the batteries at different positions on the second battery conveying rail 422 and move them to the trays in the fourth bin 431.

[0053] The detection method of the above-mentioned full-automatic workpiece detection device is as follows: Step S101: The operator places the tray stack containing the batteries to be detected in the first bin 111, and the first bin 111 lifts the tray stack to a predetermined height; Step S102: The first tray handling component 123 transports the topmost tray to one of the tray placement seats 122. The tray placement seat 122 drives the tray to move to the loading station of the first battery handling component 130. Two groups of the first battery handling components 130 alternately transport the batteries to be detected to the battery transfer component 140. At the same time, the first tray handling component 123 transports the next tray to another tray placement seat 122. After all the batteries to be detected in the previous tray are taken out, the second tray handling component 124 transports the empty tray into the second bin 112. At the same time, another tray placement seat 122 drives the next full tray to move to the loading station of the first battery handling component 130, realizing continuous loading of the first battery handling component 130; Step S103: After receiving the batteries to be detected, the battery transfer component 140 controls the third rotating seat 141 to rotate and transports the batteries to be detected to the first detection mechanism 200 one by one; Step S104: The batteries to be detected are sequentially transferred to the first suction cup component 221. The first rotating seat 210 rotates, driving the first suction cup component 221 to perform a circular motion. When each first suction cup component 221 drives the battery to be detected into the first detection area and the second detection area, the battery is detected by the first detection unit 230 and the second detection unit 330 respectively. After the detection is completed, the battery is sequentially transported to the second detection mechanism 300; Step S105: The batteries to be detected are sequentially transferred to the second suction cup component 321. The second rotating seat 310 rotates, driving the first suction cup component 221 to perform a circular motion. When each second suction cup component 321 drives the battery to be detected into the detection area of each second detection unit 330, the battery is detected by the corresponding second detection unit 330. After all the items are detected, the battery is sequentially transported to the second battery handling component 410; Step S106: The second battery handling component 410 places the qualified batteries on the first battery conveying rail 421 and places the defective batteries on the second battery conveying rail 422. The battery handling robot 423 transports the finished batteries on the first battery conveying rail 421 to the trays in the third bin 431. The defective battery handling component 424 transports the defective batteries on the second battery conveying rail 422 to the trays in the fourth bin 431; Step S107: After the tray stacks in the third bin 431 and the fourth bin 431 are full, the tray stacks are conveyed outwards and taken out by the operator.

[0054] Therefore, the technical solution of this application uses a rotating base to drive several battery fixing seats to perform circular motion, and several detection units are arranged in the annular displacement path generated by the batteries. This not only realizes the mutual association of all detection stations, but also enables several batteries to be detected to continuously and sequentially perform all items of detection, effectively improving the detection efficiency. In addition, all detection stations are arranged in a circular shape, effectively reducing the occupied space of the detection stations.

[0055] In addition to the above embodiments, the present invention may also have other implementation manners; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope required by the present invention.
