Description

Technical Field

[0001] The utility model relates to the technical field of charging pile molding, and particularly relates to an assembly mechanism for an interface of an electric vehicle charging pile. Background Technique

[0002] With the popularization of new energy vehicles, the use of electric vehicles is becoming more and more extensive. When an electric vehicle is in use, it needs to be charged. Therefore, there are more and more public or private electric vehicle charging piles. The interface of an electric vehicle charging pile is formed by die casting. After die casting, it is also necessary to carry out grinding, sand blasting, precision machining, etc. During precision machining, it is necessary to assemble a nut with the die-cast interface of the electric vehicle charging pile, and usually a riveting process is adopted.

[0003] During riveting, the formed fitting of the interface of the electric vehicle charging pile is placed on the workbench of the riveting machine, and then the nuts are sequentially placed on each through hole manually, and then the riveting machine is started to press the nuts into the through holes. During actual riveting, it is easy to have omissions when placing the nuts manually. Nuts are omitted at some through holes, making the charging interface a defective product. And sometimes the omission situation cannot be detected in time, which affects the normal use of the charging port of the charging pile during subsequent installation and use. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an assembly mechanism for an interface of an electric vehicle charging pile, which can automatically place nuts and avoid problems caused by manual operation errors.

[0005] For this reason, the technical solution of the utility model is: an assembly mechanism for an interface of an electric vehicle charging pile, including a nut feeding area, a riveting area, a moving seat and a conveying mechanism. The conveying mechanism drives the moving seat to move from the nut feeding area to the riveting area. An installation groove for placing the interface of the electric vehicle charging pile is arranged in the moving seat; the nut feeding area includes a transfer manipulator and a nut storage area. There are 4 vacuum suction cups below the transfer manipulator, and 4 storage cylinders are arranged in the nut storage area, and the positions of the storage cylinders are opposite to the positions of the 4 vacuum suction cups; the transfer manipulator is used to put nuts into the through holes of the interface of the electric vehicle charging pile; a riveting machine is arranged in the riveting area, and a pressing part that can be pressed down is arranged on the riveting machine.

[0006] Based on the above solution and as a preferred solution of the above solution: A camera unit is arranged in the middle of the transfer manipulator for identifying the positions of the through holes of the interface of the electric vehicle charging pile.

[0007] Based on the above solution and as a preferred solution of the above solution: The storage cylinder is of a hollow structure, the internal through hole is of a hexagonal structure, a support plate is arranged inside the storage cylinder, a support spring is arranged below the support plate, and the nuts are stacked above the support plate.

[0008] On the basis of the above solution and as a preferred solution of the above solution: An optoelectronic detection sensor is provided at the top of the storage cylinder, with one side as the transmitting end and the other side as the receiving end, for detecting the discharge of nuts.

[0009] On the basis of the above solution and as a preferred solution of the above solution: The material transfer manipulator is installed on the cross-shaped moving module and can move in the horizontal and vertical directions.

[0010] During use, the moving seat is located in the nut feeding area, and the die-cast automobile charging pile interface is placed in the placement groove of the moving seat. The material transfer manipulator sucks the nut from the storage cylinder in the nut storage area. When taking away the nut, the optoelectronic detection sensor provided at the top of the storage cylinder can detect the discharge of the nut. If the detection data of one of the optoelectronic detection sensors is abnormal, it means that there may be a suction cup that has not adsorbed the nut, so an error is reported; if there is no abnormality, it means that all 4 vacuum suction cups have adsorbed the nut. The material transfer manipulator moves above the automobile charging pile interface and then moves down to place the nut into the through hole of the automobile charging pile interface. The camera unit can be used to identify the position of the through hole of the automobile charging pile interface to prevent the nut from being placed incorrectly.

[0011] At the same time, after the nut above the storage cylinder is taken away, the spring will push up the support plate upward, causing the nuts to move up one position in sequence, facilitating the adsorption by the vacuum suction cup.

[0012] After the nut is placed, the conveying mechanism sends the moving seat into the riveting area, located under the riveting machine. A blocking block is provided on the side of the conveying mechanism to limit the moving seat, so that the four riveting heads on the riveting part are opposite to the position of the nut. The riveting part moves down to completely press the nut into the through hole of the automobile charging pile interface to complete the assembly operation.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The material transfer manipulator is used to complete the nut feeding work, and the optoelectronic detection sensor is used to detect the discharge of the nut to prevent the situation of nut omission; the camera unit is used to identify the position of the through hole, which is convenient for the material transfer manipulator to align with the through hole and place the nut. The operation is simple and convenient, and there will be no problems such as nut omission and skew, ensuring the quality of the final product. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In addition, if there are terms such as "first" and "second", they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meanings of "several" and "a number of" are two or more, unless otherwise specifically and clearly defined.

[0022] Referring to the attached drawings. The assembly mechanism of the vehicle charging pile interface described in this embodiment includes a nut feeding area 1, a riveting area 2, a moving seat 3 and a conveyor mechanism 4. The conveyor mechanism 4 drives the moving seat 3 to move from the nut feeding area 1 to the riveting area 2. Here, the conveyor mechanism is a conventional roller conveyor structure in the prior art, and it can complete the position switching of the moving seat.

[0023] The moving seat 3 is provided with a placement groove 31 for placing the vehicle charging pile interface 5; the nut feeding area 1 includes a material transfer manipulator 11 and a nut storage area. The middle of the material transfer manipulator 11 is provided with a camera unit 12 for identifying the position of the through hole 51 of the vehicle charging pile interface 5. There are 4 vacuum suction cups 13 under the material transfer manipulator 11, and the spacing of the 4 vacuum suction cups 13 is the same as that of the 4 through holes 51 of the vehicle charging pile interface 5.

[0024] The transfer manipulator 11 is installed on a cross-shaped moving module, that is, it includes a horizontal first linear module 14 and a vertical second linear module 15, enabling the transfer manipulator to move in the horizontal and vertical directions.

[0025] The nut storage area is provided with 4 storage cylinders 6, and the spacing of the storage cylinders 6 corresponds to the positions of the 4 vacuum suction cups 13, facilitating the simultaneous adsorption of 4 nuts by the 4 vacuum suction cups; the storage cylinder 6 is of a hollow structure, and the internal through-hole is of a hexagonal structure, facilitating the placement of nuts 7, and the nuts 7 will not tilt; a support plate 61 is provided inside the storage cylinder 6, a support spring 62 is provided below the support plate 61, and the nuts 7 are stacked above the support plate 61. When the upper nut 7 is taken away by the vacuum suction cup 13, the support spring 62 will push up the support plate 61 upwards, causing the nuts 7 to move up one position in sequence, facilitating the adsorption by the vacuum suction cup 13.

[0026] An optoelectronic detection sensor 8 is provided at the top end of the storage cylinder 6, with one side as the transmitting end and the other side as the receiving end, for detecting the nut discharging condition. When the nut has not been discharged, the receiving end can receive the optoelectronic signal emitted by the transmitting end. When the vacuum suction cup takes away the nut, during the discharging process of the nut, it will pass through between the receiving end and the transmitting end, thus affecting the reception of the optoelectronic signal, whereby it can be judged whether the nut is discharged normally.

[0027] The transfer manipulator 11 is used to place the nut 7 into the through-hole 51 of the automotive charging pile interface 5; a riveting machine 21 is provided on the riveting area 2, a downwardly pressable riveting part 22 is provided on the riveting machine 21, and 4 riveting heads 23 are provided on the riveting part, which can press down the nut 7.

[0028] During use, the moving seat 3 is located in the nut feeding area 1, and the die-cast automotive charging pile interface 5 is placed in the placement groove 31 of the moving seat 3. The transfer manipulator 11 sucks the nut 7 from the storage cylinder 6 in the nut storage area. When taking away the nut 7, the optoelectronic detection sensor 8 provided at the top end of the storage cylinder 6 can detect the nut discharging. If the detection data of one of the optoelectronic detection sensors is abnormal, it indicates that perhaps a suction cup has not adsorbed the nut, thus reporting an error; if there is no abnormality, it means that the 4 vacuum suction cups have all adsorbed the nuts. The transfer manipulator 11 moves above the automotive charging pile interface 5 and then moves downwards to place the nut 7 into the through-hole 51 of the automotive charging pile interface 5. The imaging unit 12 can be used to identify the position of the through-hole of the automotive charging pile interface to prevent the nut from being placed incorrectly.

[0029] After the nut 7 is placed, the conveying mechanism 4 sends the moving seat 3 into the riveting area 2, below the riveting machine 21. A blocking block is provided on the side of the conveying mechanism to limit the moving seat, making the four riveting heads 23 on the riveting part 22 opposite to the position of the nut. The riveting part 22 moves downwards to completely press the nut 7 into the through-hole 51 of the automotive charging pile interface 5, completing the assembly operation.

[0030] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
