Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the invention may be more readily understood by those skilled in the art. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto.
Fig. 1 to 9 show an explosion-proof valve assembling device for a power battery cover plate provided by the present embodiment, which is used for realizing automatic assembling of an explosion-proof valve. The assembling equipment comprises a conveying mechanism 1, a top cover sheet feeding mechanism 2 and an explosion-proof valve feeding mechanism 3, wherein the top cover sheet feeding mechanism 2 and the explosion-proof valve feeding mechanism 3 are sequentially arranged along the conveying mechanism 1. Conveying mechanism 1 includes mobilizable carrier 13, and explosion-proof valve feed mechanism 3 includes: a positioning block 31 having a positioning groove 311; a positioning member 32; a discharge guide 33 having a guide chute 331; a rail 34 extending along the y-axis; a first pick-up head 35 movably mounted on the rail 34 along the y-axis for moving the burst valve into the positioning slot 311; a second pick-up head 36, which is movably mounted along the y-axis on the guide rail 34, is used to carry the explosion-proof valve in the positioning slot 311 through the chute 331 and into the explosion-proof valve hole in the top cover piece of the power battery carried by the carrier 13.
As shown in fig. 4 and 5, the groove wall of the positioning groove 311 gradually inclines inward from top to bottom, and the positioning element 32 is disposed below the positioning groove 311 and can move up and down to be inserted into the positioning groove 311 from the lower end. More specifically, the positioning groove 311 has opposite and open upper and lower ends, and the area of any one of the horizontal cross-sections of the positioning groove 311 is larger than the area of the horizontal cross-section therebelow, i.e., the positioning groove 311 is "wide at the top and narrow at the bottom". When the first picking head 35 is dispensing, the burst valve can drop into the locating slot 311 relatively easily. The positioning groove 311 has a specific position between the upper end and the lower end and the shape and area of the cross section thereof in the horizontal direction are identical to the shape and size of the explosion-proof valve. When the explosion-proof valve falls into the positioning slot 311, two main situations are divided: the first is that the explosion-proof valve just falls into the specific position, and the accurate positioning is automatically realized; the other is that the explosion-proof valve deviates from the specific position and even stands in the positioning groove 311, at this time, the positioning piece 32 is inserted into the positioning groove 311 to jack the explosion-proof valve, and then the explosion-proof valve moves downwards to fall along the positioning groove 311 again, and the operation can be carried out for one or more times until the explosion-proof valve just falls into the specific position to realize accurate positioning.
As shown in fig. 3, the discharging guide 33 has a material guiding slot 331 penetrating from top to bottom, and the material guiding slot 331 is a conical slot, which facilitates the insertion of the second material taking suction head 36 into the material guiding slot 331, and the conveying mechanism 1 passes below the discharging guide slot 331. In particular, the second pick-up head 36 is shaped to mate with the shape of the explosion proof valve. That is to say, the second material taking suction head 36 sucks the whole explosion-proof valve from the positioning slot 311 and the shape of the second material taking suction head can be attached to the explosion-proof valve, and when the material needs to be discharged, the second material taking suction head 36 can directly release the explosion-proof valve to penetrate the material guide slot 331 and fall on the top cover without positioning the explosion-proof valve again.
Further, the explosion-proof valve feeding mechanism 3 has a material taking working state and a material discharging working state. In a material picking mode of operation, the first and second picking tips 35 and 36 are moved in the forward direction along the y-axis, the first picking tip 35 is located upstream of the positioning member 32 to pick up two new explosion-proof valves, and the second picking tip 36 is located in the positioning slot 311 to pick up two positioned explosion-proof valves; in the discharging operation, the first material extracting nozzle 35 and the second material extracting nozzle 36 move in the reverse direction along the y-axis, the first material extracting nozzle 35 puts a new explosion-proof valve into the positioning groove 311, and the second material extracting nozzle 36 puts the positioned explosion-proof valve into the explosion-proof valve hole on the top cover plate of the carrier 13. In the discharging operation state or in the process of switching from the discharging operation state to the taking operation state, the positioning member 32 performs one or more of the following operations: the explosion-proof valve is inserted into the positioning slot 311 to jack up the explosion-proof valve, and then the explosion-proof valve moves downwards to fall down along the positioning slot 311 again until the explosion-proof valve is accurately positioned in the positioning slot 311. More specifically, the feeding mechanism of the explosion-proof valve further comprises a driving motor 7. In the discharging working state, the driving motor 7 drives the gear rack to drive the second material taking suction head 36 to move reversely along the z axis, and the positioned explosion-proof valve is placed in the discharging groove 331.
As shown in fig. 6, the explosion-proof valve feeding mechanism 3 further includes a positioning cylinder 37, the positioning cylinder 37 is disposed below the positioning block 31, the positioning cylinder 37 has a piston rod capable of reciprocating in the up-down direction, and the positioning element 32 is disposed on the piston rod of the positioning cylinder 37. When the explosion-proof valve needs to be accurately positioned, the positioning cylinder 37 drives the piston rod to move upwards, the piston rod drives the positioning piece 32 to move upwards and insert into the positioning slot 311 so as to jack the explosion-proof valve, then the positioning cylinder 37 drives the piston rod to move downwards, and the piston rod drives the positioning piece 32 to move downwards so that the explosion-proof valve falls along the positioning slot 311 again.
As shown in fig. 7 and 8, the conveying mechanism 1 further includes a carrier platform 11 moving along the x-axis, and the carrier 13 is disposed on the carrier platform 11 so as to be movable in the up-down direction.

One of the carrier 13 and the datum plate 381 is provided with a plurality of positioning guide holes 4 and the other is provided with a plurality of positioning guide pins 5 to achieve precise positioning of the top cover plate, the positioning guide pins 5 can be inserted into the corresponding positioning guide holes 4, and at least one of the positioning guide holes 4 or the positioning guide pins 5 has a positioning contact slope or a positioning contact curved surface. Specifically, in the present embodiment, the reference plate 381 is provided with the positioning guide pin 5, the positioning guide pin 5 is provided on the reference plate 381 to be capable of moving up and down, and the carrier 13 is provided with the positioning guide hole 4. The positioning guide hole 4 has a tapered hole wall 41, and the positioning guide pin 5 has a tapered portion 51, and the tapered portion 51 can be inserted into the positioning guide hole 4 and contact-fitted with the tapered hole wall 41. Since the positioning guide holes 4 and the positioning guide pins 5 have tapered structures, it is relatively easy to perform fitting, and the positioning guide pins 5 can be easily caught in the positioning guide holes 4.
Further, the loading platform 11 has a guiding pin 113 extending upward, the carrier 13 has a matching through hole 133, and the guiding pin 113 can be inserted into the through hole 133 of the carrier 13 in a detachable manner. When the carrier 13 is placed on the carrier platform 11, the guide pin 113 is inserted into the through hole 133 to position the carrier 13 and limit the carrier 13 so that the carrier 13 cannot be deviated in the horizontal direction; when the carrier 13 is jacked up until the guide pin 113 is separated from the through hole 133, the carrier 13 can be finely adjusted in the horizontal direction under the action of the upper conical positioning guide pin 5, the alignment precision of the top cover plate on the carrier 13 and the explosion-proof valve to be assembled is adjusted, and the explosion-proof valve is discharged after precise alignment is realized. Specifically, the number of the positioning guide holes 4 and the through holes 133 on the carrier 13 is plural, at least two positioning guide holes 4 are located at opposite corners, and at least two through holes 133 are located at opposite corners.

Other portions (i.e., the suspended portion) of the carrier platform 11 are provided with through holes 112. The carrier 13 has a downwardly extending boss 131 capable of penetrating from the through hole 112 to a position below the platform of the carrier 13, the power source 382 is connected to a push block 132, and under the action of the power source 382, the push block 132 pushes the boss 131 to move upward. Further, a buffer spring 6 is provided between the reference plate 381 and the positioning guide pin 5. The spring 6 is provided to prevent the carrier 13 or the top cover plate from being damaged and thereby to cushion when the thrust of the power source 382 is large.

Further, the explosion-proof valve feeding mechanism 3 further comprises a second sensor 391, the second sensor 391 is used for detecting whether the carrier 13 is jacked up, and when the carrier 13 is jacked up to realize the accurate positioning of the top cover plate, the second material taking suction head 36 drives the explosion-proof valve to pass through the material guide chute 331, and then the explosion-proof valve is released and falls into an explosion-proof valve hole of the top cover plate of the power battery carried by the carrier 13.
