[0024] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0025] The following illustrates the implementation manners of the present disclosure through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0026] As Figures 1-3 shown, a single-phase intelligent electricity meter crimping drive device includes a frame 1, longitudinal slide rails 3, transverse slide rails 4, longitudinal beams 5, meter trays 2, terminal installation seats 6 and conductive pins 9; two longitudinal slide rails 3 are provided on the frame 1, 15 meter trays 2 are arranged on the same longitudinal slide rail 3, correspondingly, two longitudinal beams 5 are provided, and 15 terminal installation seats 6 are installed on each longitudinal beam 5, that is, a total of 30 terminal installation seats; the longitudinal beams 5 move in the longitudinal direction of the frame 1 through a telescopic mechanism.

[0027] In this example, two longitudinal slide rails 3 are provided on the frame 1, 15 meter trays 2 are arranged on the same longitudinal slide rail 3, correspondingly, two longitudinal beams 5 are provided, and 15 terminal installation seats 6 are installed on each longitudinal beam 5, that is, a total of 30 terminal installation seats.

[0028] Arrange a number of electric meter trays 2 in a row on the longitudinal slide rail 3. Each electric meter tray 2 corresponds to a terminal block mounting seat 6, and place the electric meter 7 on the electric meter tray 2. When the wiring hole 8 on the electric meter 7 is aligned with the conductive pin 9 on the corresponding terminal block mounting seat 6, stop driving the movement of the electric meter tray 2. The telescopic mechanism drives the longitudinal beam 5 to move closer to the direction of the electric meter tray 2 until the conductive pin 9 is inserted into the wiring hole 8 of the electric meter and the telescopic mechanism stops driving, thus completing the wiring, and then conduct detection through the detection device.

[0029] In this embodiment, the telescopic mechanism is a cylinder. It is simple and practical.

[0030] In this embodiment, the terminal block mounting seat 6 is provided with a conductive pin connection hole. The conductive pin 9 is connected in the conductive pin connection hole through an insulating sleeve. A wire is connected to the conductive pin 9. During use, the wire is connected to the detection device. The insulating sleeve is used to isolate the external power supply to avoid the external power supply affecting the detection device.

[0031] In this embodiment, a connecting ear 10 is provided on the frame 1. The connecting ear 10 is hinged with a swing rod 12 through a transverse shaft pin 11, and the swing rod 12 is connected to a swing cylinder 13. The swing rod 12 swings and positions under the drive of the swing cylinder 13. The electric meter tray 2 moves on the longitudinal slide rail 3. When it moves to be blocked by the swing rod 12, the wiring holes 8 of the electric meters located on the electric meter tray 2 are aligned with the conductive pins 9 on the corresponding terminal block mounting seats 6 one by one. The swing rod 12 and the swing cylinder 13 make the electric meter tray 2 stop at the required position. After the detection is completed, the swing cylinder 13 drives the swing rod 12 to swing below the longitudinal slide rail 3 for avoidance. Other mechanisms can be used to remove the electric meter tray 2 and the electric meter, such as a manipulator.

[0032] Such as Figures 4-6As shown in the figure, in this embodiment, it further includes a conductive needle driving device, which includes a driving cylinder 18, a driving rod 17, a movable contact 15 and a conductive rubber 16; there is an avoidance hole 14 inside the side of the conductive needle 9 away from the meter tray 2, a driving rod 17 is arranged in the avoidance hole 14, the driving rod 17 is controlled to move by the driving cylinder 18, movable contacts 15 are circumferentially distributed on the conductive needle 9, the movable contacts 15 extend into the avoidance hole 14, and the movable contacts 15 are connected to the conductive needle 9 through an elastic conductive rubber 16. The way of inserting the conductive needle 9 for conduction is prone to poor contact due to reasons such as manufacturing accuracy or wear. This embodiment can solve this problem. The specific wiring process is as follows: First, insert the conductive needle 9 into the wiring hole 8 of the electric meter 7 to the set depth, and then the driving cylinder 18 drives the driving rod 17 to move towards the inside of the avoidance through hole. The insertion of the driving rod 17 causes the movable contact 15 to be extruded and extended, tightly pressing against the hole wall of the wiring hole 8, so that the conductive needle 9 and the wiring hole 8 are reliably in contact with each other. This method will not cause wear and damage, and can ensure the service life; it can change the extended length of the movable contact 15 by adjusting the insertion depth of the driving rod 17, so that the conductive needle 9 can also be reliably connected to the wiring hole 8 when there is a manufacturing error. A chute 24 extending radially along the conductive needle 9 is provided on the side of the movable contact 15 facing the inner end of the avoidance hole 14. A slider 25 is slidably connected in the chute 24. The slider 25 can prevent the movable contact 15 from swinging when it expands and contracts, resulting in a large error in the extended length of the movable contact 15, thereby affecting the conduction reliability.

[0033] In this embodiment, the driving rods 17 in all the conductive needles 9 on the same wiring head mounting seat 6 are driven by the same driving cylinder 18, which is beneficial to improving the compactness and synchronism of the mechanism.

[0034] In this embodiment, the head of the driving rod 17 is conical, or the front end of the driving rod 17 is detachably connected to a conical head 20. The conical peripheral surface constitutes a commutation surface 19, which increases the expansion and contraction stroke of the movable contact 15. Specifically, both the driving rod 17 and the conical head 20 are made of insulating materials, which can improve electrical safety.

[0035] Specifically, the detachable connection between the driving rod 17 and the conical head 20 can reduce the maintenance cost. The detachable connection adopts a magnetic attraction method, which is convenient for installation and disassembly. A connecting pin 21 and a permanent magnet 22 are provided on the inner end surface of the driving rod 17, a connecting hole and a ferromagnetic body 23 are provided on the end surface of the conical head 20, the connecting pin 21 is inserted into the connecting hole, and the permanent magnet 22 adsorbs the ferromagnetic body 23 to fix the conical head 20 on the driving rod 17.

[0036] A single-phase intelligent electric energy meter crimping driving device of the present invention can wire multiple electric energy meters simultaneously, can automatically and accurately insert the conductive needle into the meter wiring hole, making it labor-saving when detecting the electric energy meter and improving the detection efficiency.
