Detailed Description

The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.

Referring to fig. 1, a swing arm type static battery weighing apparatus according to the present embodiment includes a first battery conveying line 1, a weighing station 2, a swing arm adsorption device 3, and a second battery conveying line 4, wherein the weighing station 2 is disposed between the first battery conveying line 1 and the second battery conveying line 4, and the first battery conveying line 1 and the second battery conveying line 4 have the same structure, mainly a sprocket conveying structure. As shown in fig. 2, a guide roller 101 is disposed on each chain link of the sprocket conveying structure, and a groove is formed between adjacent guide rollers 101 for carrying the battery 5. The first battery transfer line 1 and the second battery transfer line 4 are provided so that transfer directions are parallel to each other.

As shown in fig. 3 to fig. 5, the weighing station 2 is provided with a frame 201, a battery positioning plate 202 and a plurality of weighing sensors 203, and the weighing sensors 203 are sequentially fixed on the frame 201 in a straight line. The pitch of the load cells 203 is the same as the arrangement pitch of the batteries 5 on the first battery conveying line 1 and the second battery conveying line 4, and the arrangement direction of the load cells 203 is parallel to the conveying direction of the first battery conveying line 1 and the second battery conveying line 4, so that the batteries 5 can be translated from the first battery conveying line 1 to the load cells 203 and then translated from the load cells 203 to the second battery conveying line 4. The top end of the load cell 203 is provided with a V-shaped groove 2031 so that the battery 5 can be stably weighed. In order to avoid the large impact caused by the weighing sensor 203 when the battery 5 is transferred, a battery positioning plate 202 is provided, the battery positioning plate 202 is provided with a wavy surface, the trough position of the wavy surface is provided with guide holes 202a, the positions of the guide holes 202a are opposite to the positions of the weighing sensors 203, and the distances between the guide holes 202a and the weighing sensors 203 are the same. The lengthwise direction of the battery positioning plate 2 is extended in the arrangement direction of the load cells 203. Lifting rods 204 are arranged at two ends of the rack 201, which are positioned at the queue of the weighing sensors 203, a lining 205 matched with the lifting rods 204 is arranged on the rack 201, and a pressure spring 206 is arranged at the bottom of the lifting rods 204 in the lining 205. The top of the lifting rod 204 is fixedly connected with the two ends of the battery positioning plate 202. When a downward force is applied to the battery positioning plate 202, the lifting rod 204 moves down in the bushing 205 and compresses the compression spring 206, the battery positioning plate 202 moves down, and the load cell 203 moves up relative to the guide hole 202a and rises from the wavy surface of the battery positioning plate 202. When the downward pressure on the battery positioning plate 202 is removed, the spring 206 provides the elastic force to move the lifting rod 204 upwards in the bushing 205, the battery positioning plate 202 rises, and the load cell 203 descends relative to the guide hole 202a to retract into the guide hole 202 a.

The swing arm adsorption device 3 is used for transferring the batteries 5 of the first battery conveying line 1 to the weighing station 2 and transferring the batteries of the weighing station 2 to the second battery conveying line 4. In order to improve the weighing efficiency, the movement from the first battery conveyor line 1 to the weighing station 2 and the movement from the weighing station 2 to the second battery conveyor line 4 are performed simultaneously. The swing arm adsorption device 3 comprises a first swing arm 301 and a second swing arm 302, wherein the first swing arm 301 is provided with a first swing shaft 303, the second swing arm 302 is provided with a second swing shaft 304, the first swing shaft 303 and the second swing shaft 304 are both provided with a gear 305 which is meshed with a driving gear 307 of a driving shaft 306, and when the driving shaft 306 rotates, the first swing shaft 303 and the second swing shaft 304 synchronously rotate in the same direction. The first swing arm 301 is disposed at both ends of the first swing shaft 303, and a head end of the first swing arm 301 is hinged to the first adsorption rod 308. The first suction rod 308 is provided with a plurality of first suction heads 309 arranged in the transport direction of the first battery transport line 1, and the first suction heads 309 may be vacuum-sucked (in the present embodiment), or may be electromagnetically-sucked. The pitch between the first suction heads 309 is the same as the pitch between the batteries 5 and the pitch between the load cells 203. As the first swing arm 301 swings, the first suction head 309 reciprocates back and forth above the first battery conveyor line 4 and above the load cell 203. Similar to the first swing arm 301, the second swing arm 302 is provided at both ends of the second swing shaft 304, and the head end of the second swing arm 302 is hinged to the second adsorption lever 310. The second suction rod 310 is provided with a plurality of second suction heads 311 arranged in the direction of conveyance of the second battery conveying line 4, and the second suction heads 311 may be vacuum-sucked (in the present embodiment), or may be electromagnetically sucked. The pitch between the second suction heads 311 is the same as the pitch between the batteries 5 and the pitch between the load cells 203. As the second swing arm 302 swings, the second suction head 311 reciprocates back and forth above the second battery conveyor line 4 and above the load cell 203. As shown in fig. 6, an eccentric cam 312 is further disposed on the second swing shaft 304, the eccentric cam 312 rotates with the rotation of the second swing shaft 304, and the outer edge of the eccentric cam 312 contacts with the top surface of the battery positioning plate 202. When the second swing arm 302 drives the second adsorption rod 310 to be in the middle position between the second battery conveying line 4 and the weighing station 2, the long radius position of the outer edge of the eccentric cam 312 is in contact with the top surface of the battery positioning plate 202, the battery positioning plate 202 is in the low position, the battery 5 is supported by the weighing sensor 203, and the weighing sensor 203 weighs the battery 5; when the second swing arm 302 drives the second adsorption rod 310 to be positioned above the second battery conveying line 4 or the weighing station 2, the short radius position of the outer edge of the eccentric cam 312 contacts with the top surface of the battery positioning plate 202, the battery positioning plate 202 is in the high position, and the battery 5 is supported by the battery positioning plate 202. Thus, when the second swing arm 302 rotates between the second battery conveying line 4 and the weighing station 2, the battery positioning plate 202 is lowered and raised once to complete weighing.

The specific working process of the device is that the batteries 5 are sequentially arranged on the first battery conveying line 1 for conveying, when the batteries are conveyed to the side of the weighing station 2, the first swing arm 301 and the second swing arm 302 are driven by the driving shaft 306 to rotate, the first adsorption rod 308 moves to the first battery conveying line 1 from the upper part of the weighing station 2, meanwhile, the second adsorption rod 310 moves to the weighing station 2 from the upper part of the second battery conveying line 4, the first adsorption head 309 of the first adsorption rod 308 adsorbs the batteries 5 and then moves to the weighing station 2, and because no battery 5 exists on the weighing station 2 in an initial state, the second adsorption head 311 of the second adsorption rod 310 moves to the second battery conveying line 4 in an idle position. When the first adsorption bar 308 reaches above the weighing station 2, the first adsorption head 309 releases the batteries 5, the batteries 5 are carried by the battery positioning plate 202, and then the first adsorption bar 308 moves from above the weighing station 2 to the first battery transfer line 1, and the second adsorption bar 310 moves from above the second battery transfer line 4 to the weighing station 2 in synchronization. In this process, the battery 5 is supported by the load cell 203 for weighing, because the battery positioning plate 202 is moved down by the eccentric cam 312. When the first adsorption bar 308 moves to the first battery transfer line 1, the battery 5 is lifted up from the load cell 203 by the battery positioning plate 202, the second batch of batteries 5 are adsorbed by the first adsorption head 309 of the first adsorption bar 308, and the first batch of batteries 5 which have just been weighed are adsorbed by the second adsorption head 311 of the second adsorption bar 310. When the first adsorption rod 308 reaches the upper part of the weighing station 2, the first adsorption head 309 releases the second batch of batteries 5, the second batch of batteries 5 are carried by the battery positioning plate 202, at this time, the second adsorption rod 310 moves to the upper part of the second battery conveying line 4, the second adsorption head 311 releases the first batch of batteries 5 to the second battery conveying line 4 for conveying, and the weighing of all the batteries 5 can be completed by the circulation.
