Detailed Description
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a welding spot detection device for a cylindrical battery cap provided in the present application, fig. 2 is a partial structural diagram of a main viewing angle of the welding spot detection device of fig. 1 without an air blowing assembly 140, and fig. 3 is a partial structural diagram of a main viewing angle of the welding spot detection device of fig. 1 with the air blowing assembly 140. The application discloses cylinder battery block's solder joint detection device includes: a main body frame 10, wherein the main body frame 10 comprises a lower upright 100 and an upper upright 102 arranged at the upper end of the lower upright 100; the tensile testing mechanism 12, the tensile testing mechanism 12 is arranged on the upper upright post 102, the tensile testing mechanism 12 comprises a clamping component 120 and a tensile sensor 122, the clamping component 120 is used for clamping and moving the cap 184, and the tensile sensor 122 is used for sensing that the clamping component 120 is subjected to downward tensile force; the processor 16, the processor 16 is respectively connected with the clamping assembly 120 and the tension sensor 122, after the clamping assembly 120 clamps the cap 184, the processor 16 is used for: when the pulling force sensed by the pulling force sensor 122 is smaller than a preset first pulling force threshold value, the welding point of the cap 184 is determined to be unqualified.
It is understood that the tension sensor 122 may sense that the clamping assembly 120 is under a downward tension after the clamping assembly 120 clamps the cap 184, the tension being received by the clamping assembly 120 due to the weight of the cap 184 when the clamping assembly 120 clamps the cap 184; the preset first threshold tension value may be set by a designer or a user, for example, the first threshold tension value may be set to be slightly greater than the pressure that can be generated by the weight of one of the caps 184. Therefore, when the pulling force sensed by the pulling force sensor 122 is smaller than the preset first pulling force threshold, that is, the pulling force applied to the clamping assembly 120 is insufficient, which indicates that the welding between the cap 184 and the cylindrical battery main body 180 is not firm, the clamping assembly 120 and the cap 184 fall off after clamping the cap 184, and at this time, it can be determined that the welding point of the cap 184 is not qualified. This application makes the in-process that promotes at centre gripping subassembly 120 just can detect out the unqualified cylinder battery cap of solder joint to can judge whether the welding of cylinder battery cap is firm in promoting, judge more accurately, whole solder joint detection achievement's work efficiency is higher.
further, the processor 16 is further configured to: when the pulling force sensed by the pulling force sensor 122 is greater than or equal to a preset second pulling force threshold value, judging that the welding spot of the cap 184 is qualified, and controlling the clamping assembly 120 to move the cap 184 to a preset position; wherein the first tension threshold is less than the second tension threshold. It is understood that the first threshold tension value is less than the second threshold tension value, and the predetermined second threshold tension value can be set by the designer or user, for example, the second threshold tension value can be set to be slightly less than or equal to the pressure generated by the weight of a cap 184 plus a cylindrical battery body 180 (including tab 182). Therefore, when the pulling force sensed by the pulling force sensor 122 is greater than or equal to the preset second pulling force threshold, that is, the pulling force applied by the cap 184 to the clamping assembly 120 is enough, which indicates that the welding between the cap 184 and the cylindrical battery main body 180 is firm, and the cap 184 and the clamping assembly 120 do not fall off after clamping the cap 184, at this time, it can be determined that the welding point of the cap 184 is qualified; for a solder-qualified cap 184, the processor 16 may continue to control the clamping assembly 120 to move the cap 184 to a predetermined position along with the soldered cylindrical battery body 180. The preset position of the battery automatic production device can be a storage position of a cylindrical battery qualified in welding spot detection of the current process in battery automatic production, and can also be a starting station of the cylindrical battery in the next process.
Further, the welding spot detection device for the cylindrical battery cap further comprises a cap collecting mechanism 14; the cap collecting mechanism 14 includes a blowing assembly 140 and a receiving channel 142, the blowing assembly 140 is disposed opposite to the receiving channel 142, and the blowing assembly 140 is used for blowing air toward the receiving channel 142. After the processor 16 determines that the welding point of the cap 184 is not qualified, the processor 16 may further be configured to: the clamping assembly 120 is controlled to move the cap 184 to the first position between the blowing assembly 140 and the material receiving channel 142 and then release the cap 184 so that the blowing assembly 140 blows the cap 184 into the material receiving channel 142.
It is understood that for the cap 184 with an unacceptable weld, the processor 16 may continue to control the clamping assembly 120 to move the cap 184 to the first position between the air blowing assembly 140 and the material receiving channel 142 and then control the clamping assembly 120 to release the cap 184, and then the air blowing assembly 140 may blow the cap 184 that has been detached from the cylindrical battery body 180 into the material receiving channel 142. This application makes just can judge the unqualified block 184 of solder joint at the in-process that centre gripping subassembly 120 promoted to can accomplish the work of getting rid of and collecting of unqualified block 184 afterwards, whole solder joint detection work is more simple and convenient, and work efficiency is higher.
as an implementation, the receiving channel 142 may include a feeding inlet 1420 and a discharging outlet (not shown), wherein the feeding inlet 1420 is located on the lower column 100 near the air blowing assembly 140, and the discharging outlet is located on the lower column 100 far from the air blowing assembly 140; wherein, a material receiving box 1422 is arranged below the material outlet. It can be understood that, as shown in fig. 2 and 3, the opening position of the feeding hole 1420 should be lower than the position of the blowing assembly 140, and the first position between the blowing assembly 140 and the receiving channel 142 of the present application may be set to be horizontal to the nozzle of the blowing assembly 140, at this time, after the clamping assembly 120 moves the cap 184 to the first position and releases the cap 184, which has been detached from the cylindrical battery body 180, may perform a horizontal throwing motion under the action of its own weight and the force applied by the blowing assembly 140, so that the cap 184 may be blown into the feeding hole 1420 of the receiving channel 142 from the first position and may fall into the receiving box 1422 disposed below the discharging hole, thereby completing the collecting operation of the unqualified cap 184.
Further, a first baffle 1424 is arranged above the discharge hole; a second baffle 1426 is disposed on each side of the feed port 1420. It will be appreciated that, because the receiving bin 1422 is disposed below the discharge port, when the cap 184 is blown into the feed port 1420 of the receiving channel 142 from the first position and discharged from the discharge port, the cap 184 may fly directly through the receiving bin 1422 due to the faster speed of the cap 184; therefore, by arranging the first baffle 1424 above the discharge port, and the first baffle 1424 should extend to the front of the discharge port, the cap 184 with higher speed flies out of the discharge port and then impacts on the first baffle 1424, and then falls into the material receiving box 1422, so that the cap 184 can be prevented from flying out of the discharge port and not falling into the material receiving box 1422. In addition, a certain deviation may exist in the position where the nozzle of the blowing assembly 140 blows air to the caps 184, and since the feed port 1420 cannot be designed to be infinite, the line of the horizontal throwing motion of the caps 184 may not be directly opposite to the feed port 1420, and may fly to both sides of the feed port 1420, and the second baffles 1426 respectively disposed at both sides of the feed port 1420 may cause the flying lines of the caps 184 flying to both sides of the feed port 1420 to be folded toward the feed port 1420 after hitting the second baffles 1426, so that the caps 184 which are not welded may be accurately collected.
In one embodiment, the upper column 102 is provided with a slide rail 104; the clamp assembly 120 includes a first link 1200, a drive member 1202, and a gas claw 1204; one end of the first connecting piece 1200 is slidably arranged on the sliding rail 104, and the other end of the first connecting piece 1200 is fixedly connected with the pneumatic claw 1204; the driving part 1202 is disposed on the upper column 102, and is used for driving the first connecting piece 1200 to move on the sliding rail 104; the gas claw 1204 is used to hold the cap 184. Wherein the driving member 1202 may be a motor or other power device. It can be understood that after the pneumatic claw 1204 clamps the cap 184, the driving part 1202 drives the first connecting member 1200 to move upward on the slide rail 104, and at this time, the pneumatic claw 1204 fixedly connected to the first connecting member 1200 can move upward, so as to drive the cap 184 clamped by the pneumatic claw 1204 and the whole battery to move upward.
It will be appreciated that before the processor 16 performs the determination of whether the solder joint of the cap 184 is acceptable or unacceptable, the processor 16 may also be configured to: after the pneumatic claw 1204 clamps the cap 184, the driving part 1202 is controlled to drive the first connecting piece 1200 to drive the pneumatic claw 1204 to move upwards on the slide rail 104, so that the pneumatic claw 1204 drives the cap 184 to move upwards to the second position; wherein the first position is higher than the second position. It can be understood that when the gas claw 1204 drives the clamped cap 184 and the whole battery to move upwards, even if the welding of the cap 184 is not firm, the clamped cap 184 and the whole battery may not fall off from the cylindrical battery main body 180, and at this time, if the welding point of the cap 184 is judged to be qualified or unqualified according to the pulling force sensed by the pulling force sensor 122, an error exists, so that after the gas claw 1204 drives the cap 184 to move upwards and reach the second position, the welding point of the cap 184 is judged to be qualified or unqualified according to the pulling force sensed by the pulling force sensor 122, so that the judgment of the welding point of the cap 184 is more accurate; wherein the second position may be preset, for example the height of a cap, etc. In addition, because the first position is higher than the second position, when it is determined that the cap 184 is not welded to the battery, the blowing assembly 140 is started to blow air while the cap 184 is continuously pulled upward, and the cap 184 which is not welded to be firm can be blown to the material receiving channel 142 and then collected by the material receiving box 1422, so that the cap 184 which is not qualified in welding spot can be determined in the process of lifting the clamping assembly 120, and the cap 184 which is not qualified in welding spot can be removed and collected in the lifting process, so that the whole welding spot detection work is simpler and more convenient, and the work efficiency is higher.
Further, clamp assembly 120 may also include a second connector 1206; the driving part 1202 may be a driving cylinder, and includes a cylinder body 12020 and a piston rod 12022; one end of a second connecting piece 1206 is slidably arranged on the slide rail 104, and the other end of the second connecting piece 1206 is fixedly connected with the cylinder main body 12020; one end of a piston rod 12022 is connected to the cylinder body 12020, and the other end of the piston rod 12022 is inserted into the first connecting member 1200.
It can be understood that, since the preset second pulling force threshold is greater than the preset first pulling force threshold, when the pulling force sensed by the pulling force sensor 122 is less than the preset second pulling force threshold, there are two situations: in the first case, the pulling force sensed by the pulling force sensor 122 is smaller than a preset first pulling force threshold, that is, the pulling force applied to the clamping assembly 120 is insufficient, which indicates that the welding between the cap 184 and the cylindrical battery main body 180 is not firm, and the clamping assembly 120 and the cap 184 fall off after clamping the cap 184, and at this time, the welding point of the cap 184 is not qualified; the second situation is that the pulling force sensed by the pulling force sensor 122 is greater than the preset first pulling force threshold but has not yet reached the preset second pulling force threshold, and at this time, the clamped cap 184 needs to be driven to move upwards continuously, so as to further determine whether the welding of the cap 184 is firm. Because the piston rod 12022 is fixedly connected to the first connecting member 1200 in this application, when the clamping assembly 120 is subjected to a downward pulling force less than the second pulling force threshold, there is no relative displacement between the connecting point between the piston rod 12022 and the first connecting member 1200 and the cylinder body 12020, and when the clamping assembly 120 is subjected to a downward pulling force not less than the second pulling force threshold, there is a relative displacement between the connecting point between the piston rod 12022 and the first connecting member 1200 and the cylinder body 12020. In the first instance, the clamping assembly 120 continues to move the clamped cap 184 upward until the first position is reached and the cap 184 is blown from the first position into the feed opening 1420 of the receiving channel 142. In the second situation, when the clamping assembly 120 continues to drive the clamped cap 184 to move upward, the second connecting member 1206 may move upward on the slide rail 104, and drive the piston rod 12022 and the first connecting member 1200 to move upward synchronously, so that the pneumatic claw 1204 continues to drive the clamped cap 184 to move upward; when the clamping assembly 120 is subjected to a downward pulling force to reach a second pulling force threshold, in order to prevent the gas claw 1204 from continuously driving the clamped cap 184 to move upward and thus the cap 184 and the cylindrical battery main body 180 are entirely separated from the lower supporting part, and to prevent the welding spots of the cap 184 from being subjected to an excessive pulling force and thus the originally qualified welding spots from being disconnected, the gas claw 1204 needs to be controlled not to continuously drive the cap 184 to move upward; therefore, the second connecting member 1206 can continuously move upwards on the sliding rail 104 and drive the piston rod 12022 to move upwards, but at this time, since the downward pulling force applied to the clamping assembly 120 is not less than the second pulling force threshold, the piston rod 12022 and the first connecting member 1200 can relatively move, so that the first connecting member 1200 cannot synchronously move upwards along with the piston rod 12022, and at this time, the piston rod 12022 performs a piston movement relative to the first connecting member 1200, so that the first connecting member 1200 loses the upward pulling force applied by the piston rod 12022, and thus the first connecting member 1200 cannot continuously drive the gas claw 1204 and the clamped cap 184 to move upwards, so as to provide a buffering effect for the upward moving gas claw 1204 and the clamped cap 184, and prevent the welding point of the cap 184 from being subjected to an excessive pulling force to cause the disconnection of the originally qualified welding point.
In one embodiment, the gas gripper 1204 includes a displacement plate 12040, a jaw cylinder 12042, and two clamp blocks 12044; the two clamping blocks 12044 are disposed at the bottom of the displacement plate 12040, the gripper cylinder 12042 is disposed on the displacement plate 12040, and the gripper cylinder 12042 is configured to drive the two clamping blocks 12044 to open and close. It is understood that the jaw cylinder 12042 of the present application may be disposed on the displacement plate 12040, and two clamp blocks 12044 may be disposed on the bottom of the displacement plate 12040, and then the processor 16 may be configured to: the clamping jaw air cylinder 12042 is controlled to drive the two clamping blocks 12044 to move on the displacement plate 12040, so that the two clamping blocks 12044 are opened and closed, and when the two clamping blocks 12044 are closed or opened, the cover 184 can be clamped or released.
Referring to fig. 1 to 4, fig. 4 is a schematic structural diagram of the clamping block 12044 in fig. 1. As an implementation, the opposite ends of the two clamping blocks 12044 are respectively provided with a groove 12046, and the groove 12046 is used for accommodating the tab 182 of the cylindrical battery when the two clamping blocks 12044 clamp the cap 184. It will be appreciated that since the cap 184 is welded to the cylindrical battery and the cap 184 is positioned close to the tab 182 of the cylindrical battery, the tab 182 can be received in the groove 12046 by the design of the groove 12046 when the two clamping blocks 12044 clamp the cap 184. The tab 182 can be prevented from being clamped simultaneously when the cap 184 is clamped, i.e., the tab 182 can be prevented from being damaged, and the cap 184, which is originally welded insecure due to the clamping of the tab 182, can be prevented from being separated from the cylindrical battery main body 180.
referring to fig. 5, fig. 5 is a schematic flowchart illustrating an embodiment of a method for detecting a solder joint of a cylindrical battery cap, including the following steps:
s501: the processor controls a clamping jaw cylinder in the gas claw to drive the two clamping blocks to open and close so as to clamp the cylindrical battery cap.
S502: the control driving part drives the first connecting piece to drive the gas claw to move upwards on the sliding rail, so that the gas claw drives the cylindrical battery cap to move upwards to the second position.
S503: whether the welding spot of the cylindrical battery cap is qualified or not is judged according to the downward tension applied to the gas claw sensed by the tension sensor. If the battery is qualified, the processor can continue to control the gas claw to move the cylindrical battery cap and the welded cylindrical battery to the preset position together, and the process is ended.
S504: if the cylindrical battery cap is not qualified, the driving part is controlled to drive the first connecting piece to drive the air claw to move upwards on the sliding rail continuously, so that the air claw moves the cylindrical battery cap to a first position between the air blowing assembly and the material receiving channel and then loosens the cylindrical battery cap, and the air blowing assembly blows the cylindrical battery cap into the material receiving channel; wherein the first position is higher than the second position.
It can be understood that when the clamping cover cap is driven by the gas claw to move upwards to the second position, whether the cover cap and the cylindrical battery are disconnected or not can be judged through the downward pulling force applied to the gas claw sensed by the pulling force sensor, and whether the welding spot of the cylindrical battery cover cap is qualified or not can be judged. And after the welding spot of cylinder battery cap is judged to be unqualified, because the first position is higher than the second position, the treater can control drive part drive first connecting piece and drive the gas claw upwards to continue to remove on the slide rail, so that the gas claw moves the cylinder battery cap to be located the first position between subassembly and the receipts material passageway of blowing and unclamp the cylinder battery cap, so that the subassembly of blowing blows the cylinder battery cap into and receives the material passageway, consequently, can just can judge the unqualified cylinder battery cap of welding spot at the in-process that the gas claw promoted, and can accomplish the getting rid of and the collection work of unqualified cylinder battery cap at the in-process that continues to promote, make whole welding spot detection work more simple and convenient, work efficiency is higher.
As an implementation manner, step S503 specifically includes:
When the pulling force sensed by the pulling force sensor is smaller than a preset first pulling force threshold value, judging that the welding spot of the cylindrical battery cap is unqualified; when the pulling force sensed by the pulling force sensor is greater than or equal to a preset second pulling force threshold value, judging that the welding spot of the cylindrical battery cap is qualified; wherein the first tension threshold is less than the second tension threshold.
It can be understood that when the pulling force sensed by the pulling force sensor is smaller than a preset first pulling force threshold value, that is, the downward pulling force applied to the gas claw is insufficient, it indicates that the welding between the cap and the cylindrical battery is not firm, and the gas claw and the cap of the cylindrical battery fall off after the cap of the cylindrical battery is clamped by the gas claw, and at this time, it can be judged that the welding spot of the cap of the cylindrical battery is unqualified; and when the pulling force that force sensor sensed was greater than or equal to predetermined second pulling force threshold value, the gas claw received decurrent pulling force promptly enough, explains the welding firmly between block and the cylinder battery, and both do not take place to drop behind gas claw centre gripping cylinder battery block, can judge the solder joint of cylinder battery block qualified this moment.
