DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4 As shown, an automatic connection and disconnection mechanism fully compatible with electric energy meters and terminals includes two side bracket plates 1, a lifting and moving mechanism, a multi-layer meter stand lifting platform 2 and a horizontal moving mechanism. The lifting and moving mechanism includes a vertical slide rail moving component 3, a lifting drive motor 7 and a lifting transmission component 8. The left and right sides of the multi-layer meter stand lifting platform 2 are respectively slidably connected to the side bracket plates 1 on the left and right sides through two sets of parallel vertical slide rail moving components 3. The lifting drive motor 7 is arranged at the upper end of the side bracket plate 1 on the left side. The lifting drive motor 7 is connected to the left side of the multi-layer meter stand lifting platform 2 through the lifting transmission component 8 to drive the lifting of the multi-layer meter stand lifting platform 2. The horizontal moving mechanism includes a crimping cylinder 5 and a horizontal slide rail moving component 4. The multi-layer meter stand lifting platform 2 is provided with three layers of meter stand mounting plates 201, and each layer of meter stand mounting plates 201 can be installed with meter connection and disconnection seats 203 of corresponding types and specifications. The multi-layer meter stand lifting platform 2 includes a meter stand mounting plate 201 and a lifting platform side plates 202 located on the left and right sides of the meter stand mounting plate 201. Both sides of the bottom of each layer of the meter stand mounting plate 201 are slidably connected to the lifting platform side plates 202 through a set of forward and backward horizontal slide rail moving components 4. The crimping cylinder 5 is horizontally arranged on the cylinder mounting plate 6 on the front side of the multi-layer meter stand lifting platform 2. When the meter stand mounting plate 201 of the multi-layer meter stand lifting platform 2 is vertically moved to the crimping position, the horizontal driving rod of the crimping cylinder 5 can drive the meter stand mounting plate 201 to move forward and backward.

[0024] In order to realize the lifting and lowering drive of the multi-layer table stand lifting platform 2, as Figure 3 As shown, the lifting transmission assembly 8 includes a coupling 801 and a ball screw, the lifting drive motor 7 is vertically arranged, the output shaft of the lifting drive motor 7 faces downward, the coupling 801 is connected between the output shaft of the lifting drive motor 7 and the upper end of the screw shaft 802 of the ball screw, the upper and lower ends of the screw shaft 802 of the ball screw are rotatably connected to the screw shaft seat 803, the screw shaft seat 803 is connected and fixed to the side bracket plate 1, and the ball nut 804 of the ball screw is connected and fixed to the side of the multi-layer table stand lifting platform 2 through the connecting seat 805. The vertical transmission structure of the lifting transmission assembly 8 is effectively realized, and the lifting drive of the multi-layer table stand lifting platform 2 is realized.

[0025] In order to support more types of energy meters and terminals, such as Figure 4As shown, the lifting platform side plate 202 includes a support plate 20201 and a transition plate 20202. The transition plate 20202 is detachably connected between two adjacent upper and lower support plates 20201 by bolts. In this example, there are three support plates 20201 and two transition plates 20202. The number of layers of the multi-layer meter stand lifting platform 2 can be expanded according to actual production needs, and the meter stand mounting plate 201 can be replaced to support more meter connection and disconnection seats 203 to support the connection and disconnection of more types of electric energy meters and terminals.

[0026] In order to realize the horizontal and vertical mobile support structures, such as Figure 5 As shown, the support plate 20201 includes a vertical side plate portion 202011 and a horizontal support plate portion 202012, and the horizontal support plate portion 202012 is arranged on the inner side of the vertical side plate portion 202011, as shown in FIG. Figure 2 As shown, each layer of the table base mounting plate 201 is correspondingly connected to the horizontal support plate portion 202012 of the corresponding support plate 20201 through a horizontal slide rail moving assembly 4, the horizontal slide rail moving assembly 4 includes a horizontal slide rail 401 and a matching horizontal slide groove block 402, the upper end of the horizontal slide groove block 402 is detachably connected and fixed to the bottom surface of the table base mounting plate 201, and the horizontal slide rail 401 is detachably connected and fixed to the horizontal support plate portion 202012; a connecting block 303 is provided on the outer side of the lower part of the vertical side plate portion 202011, and a vertical slide rail moving assembly 3 is connected to the outer side of the connecting block 303, the vertical slide rail moving assembly 3 includes a vertical slide rail 301 and a matching vertical slide groove block 302, the groove block and the connecting block 303 are detachably connected and fixed, and the vertical slide rail 301 is detachably connected and fixed to the side support plate 1. This structure can effectively realize the horizontal movement support structure and the vertical movement support structure for each layer of the table base mounting plate 201.

[0027] In order to prevent the table base mounting plate 201 from sliding randomly, Figure 4 As shown, an electromagnetic lock 9 is provided on the vertical side plate 202011 at a height position corresponding to each layer of the table base mounting plate 201. The electromagnetic lock 9 is detachably connected and fixed to the vertical side plate 202011 through a lock seat 10. A lock hole is provided on the side of the table base mounting plate 201 corresponding to the lock head position of the electromagnetic lock 9. The electromagnetic lock 9 is used to lock each layer of the table base mounting plate 201 to prevent the table base mounting plate 201 from sliding randomly when the multi-layer table base lifting platform 2 is moved vertically. When the table base mounting plate 201 is moved vertically to the connection and disconnection working position, the lock head of the electromagnetic lock 9 withdraws from the lock hole on the side of the table base mounting plate 201, and the table base mounting plate 201 can be driven by the crimping cylinder 5 to move horizontally.

[0028] In order to make the table base mounting plate 201 move vertically and accurately to the connection and disconnection working position, as Figure 3As shown, a positioning photoelectric sensor 11 is provided on the side bracket plate 1 at a height position corresponding to the electric energy meter and the terminal connection and disconnection work. The positioning photoelectric sensor 11 is provided on one side of one of the vertical slide rails 301. The positioning photoelectric sensor 11 is provided with a vertically penetrating induction slot, and each connecting block 303 of the vertical slide rail moving assembly 3 to which the vertical slide rail 301 belongs is connected with an induction sheet 12. When the multi-layer meter stand lifting platform 2 is used, the induction sheet 12 can move vertically through the induction slot. The positioning photoelectric sensor 11 is used for positioning when the meter stand mounting plate 201 is vertically moved to the connection and disconnection working position. When the meter stand mounting plate 201 is vertically moved to the connection and disconnection working position, the lifting drive motor 7 stops driving.

[0029] In order to prevent the multi-layer table stand lifting platform 2 from moving vertically beyond the stroke, Figure 3 As shown, a limit photoelectric sensor 13 is provided above and below the positioning photoelectric sensor 11 on the side bracket plate 1. The limit photoelectric sensor 13 is located near the upper and lower ends of the vertical slide rail moving component 3 in the height direction. A vertically penetrating sensing groove is provided on the limit photoelectric sensor 13. When the multi-layer table stand lifting platform 2 is lifted, the sensing sheet 12 can move vertically through the sensing groove. The limit photoelectric sensor 13 is used for the vertical limit of the up and down movement of the multi-layer table stand lifting platform 2 to prevent the upward or downward movement from exceeding the stroke.

[0030] In order to better avoid the multi-layer table base lifting platform 2 moving over travel, such as Figure 3 As shown, the side bracket plate 1 is provided with limit blocks 14 at the upper and lower ends of each set of vertical slide rail moving components 3, the lower end surface of the upper limit block 14 is higher than the upper limit photoelectric sensor 13, and the lower end surface of the upper limit block 14 is lower than the upper end surface of the vertical slide rail moving component 3; the upper end surface of the lower limit block 14 is lower than the lower limit photoelectric sensor 13, and the upper end surface of the lower limit block 14 is higher than the lower end surface of the vertical slide rail moving component 3. By setting the limit blocks 14, the vertical movement limit of the multi-layer table stand lifting platform 2 can be better realized, and when the limit photoelectric sensor 13 fails, the extreme limit protection is realized.

[0031] In order to realize the front and rear movement drive of the table base mounting plate 201, as Figure 6 As shown, the head of the driving rod of the crimping cylinder 5 is provided with a circumferential flange 501, and each table base mounting plate 201 is provided with a limiting groove 20101 with an anti-slip groove neck corresponding to the circumferential flange 501. When the multi-layer table base lifting platform 2 is used, the circumferential flange 501 can relatively pass vertically through the limiting groove 20101. After the table base mounting plate 201 is vertically moved to the wire connection and disconnection working position, this structure enables the limiting groove 20101 of the table base mounting plate 201 to abut against the circumferential flange 501 of the head of the driving rod of the crimping cylinder 5 in the front and back directions when the driving rod of the crimping cylinder 5 moves horizontally in the front and back directions, so as to drive the table base mounting plate 201 to move in the front and back directions.

[0032] In this embodiment, the lifting drive motor 7 is a servo motor, which is arranged on the side support plate 1 on one side of the lifting movement mechanism.

[0033] When the automatic disconnecting and wiring mechanism is used, according to the calibration needs of the actual electric energy meter calibration line, multiple sets of automatic disconnecting and wiring mechanisms can be installed on one frame, and the cylinder mounting plate 6 of each set of automatic disconnecting and wiring mechanisms are connected and fixed on the frame to realize the installation of meter connection and disconnection seats 203 of multiple electric energy meters, and realize the calibration connection and disconnection operations of different electric energy meters. When the electric energy meter corresponding to one layer of the meter seat mounting plate 201 needs to be connected and disconnected, the lifting drive motor 7 is first operated to drive the multi-layer meter seat lifting platform 2 to lift and lower the meter seat mounting plate corresponding to the need for connection and disconnection operation. 201 moves to the height position for the connection and disconnection work, and the positioning of the height position is achieved by the positioning photoelectric sensor 11. At this time, the circumferential flange 501 of the head of the driving rod of the crimping cylinder 5 is located in the limit groove 20101, and then the lock head of the electromagnetic lock 9 withdraws from the lock hole, and the lock on the meter seat mounting plate 201 is released. Then, the meter seat mounting plate 201 is moved to the working position under the drive of the crimping cylinder 5, and the meter connection and disconnection seat 203 on the meter seat mounting plate 201 is driven to perform the crimping operation on the electric energy meter. After the verification work is completed, the crimping cylinder 5 retreats to complete the wire removal operation.

[0034] The multi-layer meter holder mounting plate 201 can be provided with meter connection and disconnection holders 203 for different types of electric energy meters and terminals. The multi-layer meter holder lifting platform 2 is driven to move vertically by the lifting drive motor 7, so that the meter connection and disconnection holder 203 is moved vertically to the connection and disconnection working position, which can facilitate the connection and disconnection operations of different types of electric energy meters and terminals at the same work station, so that one electric energy meter calibration line can be compatible with the calibration of different electric energy meters and terminals, which solves the problem that the traditional electric energy meter calibration line or platform can only calibrate a single type of electric energy meter or terminal, and improves the calibration compatibility.

[0035] above Figure 1-6 The automatic connection and disconnection mechanism of a fully compatible electric energy meter and terminal shown is a specific embodiment of the present invention, which has embodied the outstanding substantial features and remarkable progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
