[0090] In this embodiment, the first and second sliding holes 5111, 5121 are both provided on the first receiving member 511 and the second receiving member 512, and the second sliding holes 5121 correspond to the first sliding holes 5111, respectively. The number of guide posts 514 is also multiple and is the same as the number of first sliding holes 5111 and second sliding holes 5121. The guide posts 514 slide through the corresponding first sliding holes 5111 and the corresponding second sliding holes 5121 in sequence, and the two ends of the guide posts 514 are respectively inserted into the opposite inner walls of the through opening 12. In this way, the stability of the first and second receiving members 511, 512 sliding on the guide posts 514 is improved.

[0091] Please refer to Figure 6 In this embodiment, the first stopper 52 and the second stopper 53 both include a rotating portion 521 and a stopper 522 connected to the rotating portion 521. The stopper 522 is provided with a through hole 5211 and an abutting groove 5212. The first rotating shaft 56 passes through the corresponding through hole 5211 and is rotatably connected to one end of the corresponding first receiving member 511 close to the abutting portion 11. The second rotating shaft 57 passes through the corresponding through hole 5211 and is rotatably connected to one end of the corresponding second receiving member 512 close to the abutting portion 11. The first stopper elastic member 54 is away from one end of the corresponding first receiving member 511. Abutting against the corresponding abutting groove 5212, one end of the second stop elastic member 55 away from the corresponding second receiving member 512 abuts against the corresponding abutting groove 5212, and the abutting groove 5212 can limit the lateral movement of the first stop elastic member 54 and the second stop elastic member 55, thereby facilitating the stability of the first stop elastic member 54 and the second stop elastic member 55 abutting against the first stop member 52 and the second stop member 53 respectively, and the stop portion 522 is wedge-shaped and extends toward one end of the receiving hole 513 close to the abutting portion 11, and the size of the stop portion 522 is smaller than that of the rotating portion 521. Since the sizes of the receiving hole 513 and the nut 200 are small, by providing a stop portion 522 with a smaller size extending toward one end of the receiving hole 513 close to the abutting portion 11 and stopping the nut 200, it is facilitating the accuracy of the first stop member 52 and the second stop member 53 stopping the nut 200.

[0092] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the guide member 60 is movably inserted into the receiving hole 513, and the guide member 60 includes a guide portion 61 and a stop portion 62 connected to one end of the guide portion 61. The guide portion 61 and the stop portion 62 are both columnar, and a plurality of nuts 200 are inserted through the guide portion 61. The stop portion 62 is coaxially arranged with the guide portion 61, and along the extension direction of the axis of the guide portion 61, the cross-sectional dimension of the guide portion 61 is smaller than the cross-sectional dimension of the stop portion 62. The stop portion 62 stops the plurality of nuts 200, thereby limiting the plurality of nuts 200 from coming out from one end of the guide portion 61 close to the stop portion 62. By providing the guide member 60, a plurality of nuts 200 can be inserted in advance on the guide portion 61. When the first receiving member 511 and the second receiving member 512 are away from each other, the blocking portion 62 can be held by hand so that the blocking portion 62 drives the guide portion 61 to extend between the first receiving groove 5131 and the second receiving groove 5132 under the action of an external force. When the first receiving member 511 and the second receiving member 512 are close to each other, the guide portion 61 is pulled out of the receiving hole 513 and the plurality of nuts 200 are stored in the receiving hole 513. In this way, the efficiency of placing the nuts 200 in the receiving hole 513 using the guide member 60 is improved.

[0093] In this embodiment, the opening and closing driving mechanism 70 includes a bracket 71, a sliding member 72 slidably connected to the bracket 71, a moving member 73 and a partition member 76 connected to the sliding member 72, a reset elastic member 77 sleeved on the sliding member 72, and a first abutting member 74 and a second abutting member 75 that slidably abut against the moving member 73. The bracket 71 is installed on the upper end surface 13 of the base 10 and is located between the pressing mechanism 80 and the base 10. The bracket 71 is generally U-shaped. The middle part of the bracket 71 has a sliding channel 711 facing the through hole 12. The bracket 71 is provided with a guiding hole 712 and a first through hole 713 extending along the first direction and communicating with the sliding channel 711. The first through hole 713 is disposed opposite to the receiving hole 513. The guiding hole 712 and the first through hole 713 are spaced apart. The sliding member 72 is columnar. The sliding member 72 slides along the first direction through the guiding hole 712 and extends towards the receiving assembly 51. The moving member 73 is installed at one end of the sliding member 72 close to the receiving assembly 51 and is located in the sliding channel 711. The moving member 73 is provided with a second through hole 7311 and relatively arranged first sliding slots 7321 and second sliding slots 7322. The second through hole 7311 is disposed opposite to the first through hole 713.

The first abutting member 74 and the second abutting member 75 are both columnar. The first abutting member 74 passes through the first sliding slot 7321 along the third direction and is connected to the first receiving member 511. The second abutting member 75 passes through the second sliding slot 7322 along the third direction and is connected to the second receiving member 512. The third direction is the length direction of the base 10. The first direction, the second direction and the third direction are perpendicular to each other in pairs. The partition member 76 is plate-shaped. The partition member 76 is installed at one end of the sliding member 72 away from the receiving assembly 51.

The multiple reset elastic members 77 are respectively sleeved on the multiple sliding members 72, and the two ends of the multiple reset elastic members 77 are respectively connected to the barrier member 76 and the bracket 71. Since the elastic force of the multiple reset elastic members 77 is larger and more stable, it is beneficial to improve the accuracy of the opening and closing drive mechanism 70 in driving the first storage member 511 and the second storage member 512 to move closer to each other.

[0097] In this embodiment, the first sliding long hole 7321, the second sliding long hole 7322, the first abutment member 74 and the second abutment member 75 are all two, the moving member 73 includes a horizontal plate 731 and two vertical plates 732 connected to the horizontal plate 731, the horizontal plate 731 is installed at one end of the sliding member 72 close to the storage component 51 and extends along the third direction, the second through hole 7311 is opened on the horizontal plate 731, the two vertical plates 732 are spaced at both ends of the horizontal plate 731 and extend along the first direction, the horizontal plate 731 and the two vertical plates 732 enclose a storage space 733, and the first storage member 511 is away from the abutment portion 11 One end of the second receiving member 512 and one end of the second receiving member 512 away from the abutting portion 11 both extend into the receiving space 733, two first sliding long holes 7321 are respectively opened and installed on the two vertical plates 732, two second sliding long holes 7322 are respectively opened on the two vertical plates 732 and located on one side of the corresponding first sliding long holes 7321, two first abutting members 74 respectively pass through the two first sliding long holes 7321 along the third direction and are connected to the two side walls of the first receiving member 511, and two second abutting members 75 respectively pass through the two second sliding long holes 7322 along the third direction and are connected to the two side walls of the second receiving member 512. When the sliding member 72 drives the moving member 73 to move, the moving member 73 drives the first receiving member 511 and the second receiving member 512 to move closer to or away from each other through the two first abutting members 74 and the two second abutting members 75, thereby facilitating the improvement of the accuracy and stability of the opening and closing driving mechanism 70 in driving the first receiving member 511 and the second receiving member 512 to open and close.

[0098] In this embodiment, the pressing mechanism 80 includes a pressing component 81 and a ejector pin 82 connected to the pressing component 81. The pressing component 81 is installed on the upper end surface 13 of the base 10, and the ejector pin 82 is installed on the pressing component 81 and is opposite to the receiving hole 513. The pressing component 81 drives the ejector pin 82 to pass through the third through hole 761, the first through hole 713 and the second through hole 7311 in sequence, and then insert into the receiving hole 513 and press the nut 200, so that the nut 200 is output from the receiving hole 513 and installed to the preset position of the workpiece.

[0099] The pressing assembly 81 includes a plurality of guide members 811 , a pressing member 812 slidably connected to the plurality of guide members 811 , and a plurality of supporting elastic members 813 respectively sleeved on the plurality of pressing members 812 .

Since the guide member 811 guides the movement direction of the pressing member 812, it is beneficial to improve the accuracy of the pressing component 81 driving the ejector pin 82 to press and eject the nut 200; when the external force is removed from the pressing member 812, the multiple supporting elastic members 813 drive the pressing member 812 away from the base 10, and the pressing member 812 drives the ejector pin 82 to be pulled out of the receiving hole 513, so that it is convenient to use the nut installation device 100 to install the nut 200 again.

[0101] In some other embodiments, the pressing component 81 is a power component such as a telescopic cylinder, an electric push rod, etc., which is not specifically limited in the embodiments of the present application.

[0102] The process of installing the nut 200 by the nut installation device 100 of the embodiment of the present application is roughly as follows:

[0103] A plurality of nuts 200 are inserted into the insertion portion 61 of the insertion member 60;

[0104] The barrier member 76 is pressed, and the barrier member 76 drives the moving member 73 to approach the first receiving member 511 and the second receiving member 512 through the sliding member 72.

The guide member 60 is moved so that the guide portion 61 drives the plurality of nuts 200 to move between the first receiving groove 5131 and the second receiving groove 5132.

[0105] The barrier member 76 is released, and the resetting elastic member 77 drives the sliding member 72 and the moving member 73 away from the first abutting member 74 and the second abutting member 75. The moving member 73 drives the first receiving member 511 and the second receiving member 512 to approach each other through the first abutting member 74 and the second abutting member 75. The guide member 60 is moved to pull the guide portion 61 out of the receiving hole 513, and the plurality of nuts 200 are received in the receiving hole 513.

[0106] The entire nut installation device 100 is placed at a corresponding position of the workpiece, and the abutting portion 11 is abutted against the workpiece, the positioning pin 20 is inserted into the positioning hole of the workpiece, and the magnetic attraction member 40 adsorbs the workpiece;

[0107] The pressing member 812 is pressed to move toward the base 10, and the pressing member 812 drives the ejector pin 82 to sequentially pass through the third through hole 761, the first through hole 713, and the second through hole 7311, and then insert into the receiving hole 513 and press against the multiple nuts 200.

The pressing member 812 drives the ejector pin 82 to be pulled out from the receiving hole 513. The first stop elastic member 54 drives the first stop elastic member 52 and the second stop elastic member 55 drives the second stop member 53 to stop the remaining multiple nuts 200.

[0109] In summary, the nut installation device 100 of the embodiment of the present application can simultaneously store multiple nuts 200 in the storage hole 513 by providing a storage hole 513 for storing the nut 200 on the storage component 51, and setting a first stop elastic member 54 to drive the first stop member 52 to stop the nut 200. By setting a pressing component 81 to drive the ejector pin 82 to insert into the storage hole 513 to press the nut 200 and eject the nut 200 from the storage hole 513, when installing the nut 200, it is only necessary to place the nut installation device 100 at the corresponding position of the workpiece and make the abutting portion 11 abut against the workpiece, and then make the pressing component 81 drive the ejector pin 82 to eject the nut 200 from the storage hole 513 to the preset position of the workpiece to complete the installation of the nut 200. In this way, the nut installation device 100 of the embodiment of the present application saves the time of installing the nut 200 to the preset position of the workpiece, and improves the efficiency of installing the nut 200.
