Description

Technical Field

[0001] The invention belongs to the technical field of electric energy meter verification, and in particular is a positioning mechanism capable of being powered synchronously for electric energy meter verification. Background Art

[0002] After the electric energy meter is assembled, its performance needs to be verified before packaging to ensure the accuracy of the electric energy meter and the stable working state of the terminal. At present, manual verification is usually used to verify the terminals of the electric energy meter, and the probe is plugged into the terminal of the electric energy meter. Its degree of automation is not high. Firstly, the work efficiency is relatively low, and the quality of verification may vary due to human factors. Therefore, it is not suitable for large-scale production verification. Secondly, there are relatively few defective electric energy meters, and long-term verification of the same specification may cause manual distraction and verification errors.

[0003] In addition, the positioning jig is customized according to the appearance parameters of the electricity meter. The immovable jig is also difficult to assemble, making it difficult to achieve automated and precise loading. The initial fit is too tight and may scratch the appearance of the electricity meter during loading, resulting in defective products.

[0004] Therefore, the present application proposes a positioning mechanism that can be powered synchronously for electric energy meter calibration to overcome the above-mentioned defects. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a positioning mechanism that can be powered synchronously for electric energy meter verification.

[0006] To achieve the above object, the present invention provides the following technical solution: Based on a positioning mechanism that can be powered synchronously for electric energy meter verification, the positioning mechanism includes a positioning fixture that is slidably arranged on an I-beam guide rail of a workbench;

[0009] The positioning fixture includes a positioning block and a positioning rod, which are respectively located at both ends and both sides of the electric meter for centering and limiting the electric meter. The positioning block is movably installed inside the electric energy meter placement cavity of the positioning fixture and is elastically connected to a guide plate through an elastic member. The guide plate cooperates with a limiting plate fixedly installed on the I-beam guide rail to compress inwards during the positioning process to extend the positioning block and thereby position the electric meter along the Y-axis direction.

[0010] The positioning fixtures on both sides of the electric meter are fixed in series through a rotating shaft and extend to the outside of the positioning fixture. They are driven to rotate by a driver located at the end of the I-beam guide rail to position the electric meter along the X-axis direction.

[0011] Preferably, the positioning block is extended to the outside of the positioning fixture through a guide rod and is fixedly connected to the guide plate, and the elastic member is elastically supported between the guide plate and the positioning fixture;

[0012] The end of the limit plate facing the X-axis direction is provided with an opening for the positioning fixture to enter. The width of one end of the limit plate along the X-axis direction is constant and the positioning fixture is located inside the limit plate so that the guide plate is pushed inward.

[0013] Preferably, the outer end of the rotating shaft is fixedly connected with a friction plate to cooperate with the driver;

[0014] The driver comprises a driving motor, a friction cylinder sleeved with the output shaft of the driving motor, and an elastic member 2 elastically supported between the driving motor fixing frame and the friction cylinder;

[0015] The friction plate is in compression contact with the friction cylinder.

[0016] Preferably, a slide groove is provided on one end of the positioning fixture close to the detection component, which is used to cooperate with the detection component to guide it.

[0017] Preferably, the detection assembly includes a probe fixing part and a probe arranged on the probe fixing part, and also includes a cylinder that pushes the probe fixing part to insert the probe into the line inlet hole of the electric meter for detection, and a guide slider is arranged below the probe fixing part;

[0018] The guide slide block slides in cooperation with the slide groove.

[0019] Preferably, the positioning mechanism also includes a supporting mechanism arranged below the positioning fixture, the supporting mechanism is composed of a cylinder, a parallelogram linkage mechanism and a supporting block, the bottom rod of the parallelogram linkage mechanism is fixedly connected to the bottom of the through groove, the upper rod of the parallelogram linkage structure is slidably installed on the bottom of the workbench partition, and the output end of the cylinder is connected to the upper rod.

[0020] Preferably, a through slot is provided inside the electric energy meter placement cavity of the positioning fixture for the top support block to pass through, and the opening cross-section of the through slot is adapted to the top cross-section of the top support block.

[0021] Preferably, the rod body of the positioning rod is processed with an arc transition on the side facing the electric energy meter placement cavity.

[0022] Preferably, the positioning mechanism further comprises a limit block 1 arranged at the end of the travel of the I-beam guide rail; and a position sensor arranged in the middle of the I-beam guide rail, which is used to detect the position of the positioning fixture.

[0023] Preferably, two suction cups are provided on the positioning mechanism, and the two suction cups are respectively arranged at the end of the I-beam guide rail and above the position sensor, and discharge mechanisms are respectively arranged below the ends of the square steel brackets of the two suction cups.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention uses a positioning jig to move along the I-beam guide rail to the workstation. When the positioning block in the positioning jig passes through the limit plate, it is pressed by the limit plate to extend out from the inner side of the electric energy meter placement cavity, thereby clamping the electric energy meter in the Y-axis direction. After reaching the end of the I-beam, the electric energy meter is limited in the X-axis direction by the docking of the rotating shaft and the driver. At this point, the electric energy meter is positioned, and then the detection component can be started to perform plug-in calibration. The horizontal movement of the positioning jig along the I-beam is completed by a linear motor. This device completes the full automatic positioning and calibration, and there is no need to position it in the loading link to increase the difficulty of loading. The end positioning method also prevents possible deflection during the movement. During the initial loading, there is no need to accurately align the jig, and it can be roughly placed, which is convenient for automatic loading and improves the calibration efficiency.

[0026] By using a parallelogram linkage mechanism for the top support mechanism, the top support block can be started to move upward synchronously to lift the electric energy meter in the positioning fixture and remove it from the fixture. The advantage of setting up this mechanism is that it reduces the space occupied by the equipment. If the cylinder is used for vertical push, it is necessary to reserve a height space including the volume of the cylinder in the vertical space. The action efficiency is high, and the unloading work is completed in conjunction with the suction cup and the discharge mechanism.

[0027] The corresponding suction cups and discharging mechanisms at the position sensor and the end of the I-beam are used to remove NG products and G products respectively. The qualified products are supported upward by the supporting mechanism at the end of the I-beam and sucked by the suction cup. A moving trolley is set on the suction cup to drive the electric energy meter to move along the extension direction of the square steel, move to the discharging mechanism, put down the electric energy meter and send it away with the conveyor belt for collection. For NG products, when the positioning fixture returns to the position sensor, the positioning fixture is controlled to stop, and the corresponding supporting mechanism at the bottom pushes the NG products upward to push them out, and they are taken away by the suction cup and sent to another discharging mechanism for transmission, which can complete the effective separation of good and defective products.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 11As shown, the present invention provides a positioning mechanism that can be powered synchronously for electric energy meter verification, the positioning mechanism comprising a positioning fixture 100, which is slidably arranged on an I-beam guide rail of a workbench;

[0042] The detection assembly 200 is disposed on one side of the I-beam guide rail and is located at the end of the travel of the positioning fixture 100 and is used to cooperate with the positioning fixture 100 to calibrate the electric meter 800;

[0043] The linear motor 600 is connected to the positioning fixture 100 to drive the positioning fixture 100 to move linearly along the I-beam guide rail;

[0044] Among them, the positioning fixture 100 includes a positioning block 101 and a positioning rod 102, which are respectively located at both ends and both sides of the electric meter 800 for centering and limiting the electric meter 800. The positioning block 101 is movably installed inside the electric energy meter placement cavity of the positioning fixture 100 and is elastically connected to a guide plate 104 through an elastic member 103. The guide plate 104 cooperates with a limiting plate 700 fixedly installed on an I-beam guide rail to compress inwards during the positioning process to extend the positioning block 101 and thereby position the electric meter 800 along the Y-axis direction;

[0045] The positioning fixtures 100 on both sides of the electric meter 800 are fixed in series through the rotating shaft 105 and extend to the outside of the positioning fixture 100. The driver 500 located at the end of the I-beam guide rail drives the electric meter 800 to rotate, thereby positioning the electric meter 800 along the X-axis direction.

[0046] The electric energy meter is roughly placed in the electric energy meter placement cavity of the positioning fixture 100 by manual or automatic conveying mechanism. It only needs to correspond to the length and width of the electric energy meter placement cavity. If the length and width do not correspond, it cannot be placed. Then the positioning fixture 100 moves to the workstation along the I-beam guide rail. When the positioning block 101 in the positioning fixture 100 passes through the limit plate 700, it is pressed by the limit plate 700 to extend from the inside of the electric energy meter placement cavity, clamping the electric energy meter in the Y-axis direction. After reaching the end of the I-beam, through the docking of the rotating shaft 105 and the driver 500, the driver 500 drives the rotating shaft 105 to rotate, causing the positioning rod 102 to rotate and lie on the edge of the electric energy meter placement cavity. This process will push the electric energy meter between the two positioning rods 102, causing the electric energy meter to be limited in the X-axis direction. At this point, the electric energy meter is positioned in the XY axis direction, and then the detection component 200 can be started to perform plug-in calibration. The horizontal movement of the positioning fixture 100 along the I-beam is completed by the linear motor 600. The device completes the full automatic positioning and verification, and there is no need to position it during the loading process to increase the difficulty of loading. The end positioning method also prevents possible deflection during the movement, which significantly improves the verification efficiency.

[0047] like Figure 1-Figure 3As shown, the positioning block 101 extends to the outside of the positioning fixture 100 through a guide rod and is fixedly connected to the guide plate 104, and the elastic member 103 is elastically supported between the guide plate 104 and the positioning fixture 100;

[0048] The end of the limiting plate 700 facing the X-axis direction is provided with an opening for the positioning fixture 100 to enter. The width of one end of the limiting plate 700 along the X-axis direction is constant and the positioning fixture 100 is located inside thereof so that the guide plate 104 is pushed inward.

[0049] When the positioning jig 100 has not moved to the inner side of the two limit plates 700, the elastic members 103 at both ends thereof are in an outwardly extended state to push the guide plate 104. The positioning block 101 in the cavity where the electric energy meter is placed is also received inside the edge of the positioning jig 100 or extends slightly inward. At this time, the electric energy meter is not in a positioned clamped state. When the positioning jig 100 moves between the limit plates 700, after the transition between the guide plate 104 and the limit plates 700 and finally being compressed, the positioning blocks 101 at both ends extend inward, first correcting the electric energy meter in the Y-axis direction, so that the electric energy meter is horizontal in the width direction of the positioning jig 100, and parallel to the probe of the detection component 200, creating good conditions for subsequent X-axis correction and preventing the positioning rod 102 from causing shear movement with the electric energy meter during correction and damaging the electric energy meter.

[0050] like Figure 4 As shown, the outer end of the rotating shaft 105 is fixedly connected with a friction plate 106 to cooperate with the driver 500;

[0051] The driver 500 includes a driving motor 501, a friction cylinder 502 sleeved on the output shaft of the driving motor 501, and an elastic member 503 elastically supported between a fixing frame of the driving motor 501 and the friction cylinder 502;

[0052] The friction plate 106 and the friction cylinder 502 are in compression contact.

[0053] When the positioning fixture 100 carries the electric energy meter to the calibration station, the friction plate 106 fits tightly with the friction cylinder 502, causing the elastic member 2 503 to be compressed. The friction cylinder 502 and the output shaft of the drive motor 501 are circumferentially limited, but can slide along the axial direction, so the elastic member 2 503 can be compressed and provide elastic force for supporting the friction cylinder 502 and the friction plate 106. The static friction between the friction plate 106 and the friction cylinder 502 allows the two to rotate coaxially with the drive motor 501. Finally, the positioning rod 102 is rotated and lowered to correct the electric energy meter that is deflected in the X-axis direction. The inner spacing of the two positioning rods 102 in the same electric energy meter placement cavity is adapted to the width of the electric energy meter, so the electric energy meter can be clamped in the middle to complete the positioning operation, so that it can be accurately docked with the detection component 200.

[0054] like Figure 2 , Figure 3 and Fig.11 As shown, a slide groove 108 is provided on one end of the positioning fixture 100 close to the detection component 200, which is used to cooperate with the detection component 200 to guide it.

[0055] The detection assembly 200 includes a probe fixing member 201 and a probe 203 disposed on the probe fixing member 201, and also includes a cylinder 202 that pushes the probe fixing member 201 to move the probe 203 into the line entry hole of the electric meter 800 for detection, and a guide slider 204 is disposed below the probe fixing member 201;

[0056] The guide slide block 204 slides in cooperation with the slide groove 108 .

[0057] After the positioning fixture 100 reaches the designated position and positions the electric energy meter therein, the probe fixing part 201 and the probe 203 are pushed as a whole by the cylinder 1 202. The positioning fixture 100 is provided with a slide groove 108 for positioning and limiting the probe 203. After the guide slider 204 passes through the slide groove 108 and is completely aligned with the positioning fixture 100, the probe 203 can be accurately inserted into the electric energy meter wire slot to start the identification process. The outer edge of the slide groove 108 is also provided in an expanded trumpet shape to improve the fault tolerance of the coordination between the mechanisms. After the verification is completed, the detection component 200 is retreated to exit the verification process. In addition, a guide sliding mechanism is also provided on the detection component 200 to assist in linear motion, which greatly reduces the probability of deflection during movement.

[0058] like Figure 5 As shown, the positioning mechanism also includes a supporting mechanism 900 disposed below the positioning fixture 100, the supporting mechanism 900 is composed of a cylinder, a parallelogram linkage mechanism and a supporting block 901, the bottom rod of the parallelogram linkage mechanism is fixedly connected to the bottom of the through slot 107, the upper rod of the parallelogram linkage structure is slidably installed at the bottom of the workbench partition, and the output end of the cylinder is connected to the upper rod;

[0059] The upper horizontal rod of the parallelogram linkage mechanism is in a sliding installation state, and it can move horizontally, while the bottom rod is fixedly connected to the bottom of the top support block 901 so that it can only move vertically. By pushing the upper rod body horizontally with the cylinder, the lower rod body is lifted upward, and the top support block 901 is moved upward synchronously to lift the electric energy meter in the positioning fixture 100 and move it out of the fixture. The advantage of setting up this mechanism is that it reduces the space occupied by the equipment. If the cylinder is used for vertical pushing, it is necessary to reserve height space including the volume of the cylinder in the vertical space. The replacement of the parallelogram linkage mechanism can better solve this defect. In addition, the mechanism has stable functions and high transmission efficiency.

[0060] like Figure 6As shown, a through slot 107 is provided inside the electric energy meter placement cavity of the positioning fixture 100 for the top support block 901 to pass through, and the opening cross-section of the through slot 107 is adapted to the top cross-section of the top support block 901 .

[0061] When the supporting block 901 supports the electric energy meter outward, it needs to pass through the positioning fixture 100 from the bottom upward. The positioning fixture 100 is provided with a through slot 107 for the supporting block 901 to penetrate through so that it can support the electric energy meter and lift it up.

[0062] like Figure 8 As shown, the rod body of the positioning rod 102 is subjected to an arc transition treatment on the side facing the electric energy meter placement cavity. The arc transition treatment is used to provide an oblique thrust to move the electric energy meter when it contacts the edge of the electric energy meter, thereby avoiding the positioning rod 102 from shearing the electric energy transformer. At the same time, the arc treatment can also prevent the surface of the electric energy meter from being scratched.

[0063] like Figure 1 and Figure 2 As shown, the positioning mechanism also includes a limit block 1001 arranged at the end of the I-beam guide rail travel; a position sensor 1002 arranged in the middle of the I-beam guide rail, which is used to detect the position of the positioning fixture 100.

[0064] The positioning fixture 100 is used to block the positioning fixture 100 at the end of the I-beam to prevent it from moving further. This position is the detection position. After reaching this position, the positioning fixture 100 can be aligned with the detection component 200 for detection. At the same time, the friction plate 106 and the friction cylinder 502 are also in close contact at this time. The driving motor 501 drives the friction cylinder 502 to rotate, which can make the friction plate 106 rotate accordingly to position the electric energy meter. The position sensor 1002 is used to detect the position of the positioning fixture 100 when it returns. When the positioning fixture 100 carries NG products to the position sensor 1002, it stops immediately, removes the defective products carried on it, and then continues to move.

[0065] like Figure 1 As shown, two suction cups 300 are disposed on the positioning mechanism, and the two suction cups 300 are respectively disposed at the end of the I-beam guide rail and above the position sensor 1002, and a discharge mechanism 400 is respectively disposed below the end of the square steel bracket of the two suction cups 300.

[0066] The position sensor 1002 and the corresponding suction cup 300 and discharge mechanism 400 at the end of the I-beam are used to remove NG products and G products respectively. The qualified products are supported upward by the support mechanism 900 at the end of the I-beam and sucked by the suction cup 300. A moving trolley is provided on the suction cup 300 to drive the electric energy meter to move along the extension direction of the square steel, move to the discharge mechanism 400, put down the electric energy meter and send it away with the conveyor belt for collection. Since the positioning fixture 100 is a multi-cavity fixture (two are shown in the figure), multiple electric energy meters can be positioned and tested at the same time. A corresponding supporting mechanism 900 is set at the bottom of each cavity. When the electric energy meter in the corresponding cavity is qualified, the supporting mechanism 900 below it is started by the controller to push the electric energy meter upward. NG products do not respond, but when the positioning fixture 100 returns to the position sensor 1002, the positioning fixture 100 is controlled to stop, and the corresponding supporting mechanism 900 below pushes upward to push out the NG products, which are taken away by the suction cup 300 and sent to another discharging mechanism 400 for transmission. Effective separation of good and defective products is formed.

[0067] The working principle and use process of the present invention:

[0068] The electric energy meter is roughly placed in the electric energy meter placement cavity of the positioning fixture 100 through a manual or automatic conveying mechanism. It only needs to correspond to the length and width of the electric energy meter placement cavity. If the length and width do not correspond, it cannot be placed in. Then the positioning fixture 100 moves to the workstation along the I-beam guide rail. When the positioning block 101 in the positioning fixture 100 passes through the limit plate 700, it is pressed by the limit plate 700 to extend from the inner side of the electric energy meter placement cavity, clamping the electric energy meter in the Y-axis direction. After reaching the end of the I-beam, through the docking of the rotating shaft 105 and the driver 500, the driver 500 drives the rotating shaft 105 to rotate, causing the positioning rod 102 to rotate and lie on the edge of the electric energy meter placement cavity. This process will push the electric energy meter between the two positioning rods 102, causing the electric energy meter to be limited in the X-axis direction. Then the detection component 200 can be driven for identification. After the identification is completed, the electric energy meter is lifted upward by the supporting mechanism 900 and removed in batches or synchronously.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
