Description

Technical Field

[0001] The invention relates to the technical field of crimping equipment, in particular to a shielding crimping device for crimping an HPLC communication module of an electric energy meter. Background Art

[0002] Low-voltage power line high-speed carrier communication, referred to as HPLC, is a power line carrier communication technology, which is mostly used in the local communication of the low-voltage area power consumption information collection system. The HPLC module of the energy meter refers to the module implemented based on HPLC technology in the energy meter, which is used to realize the communication with the concentrator and data upload function. At present, the main function of the shield crimping device of the HPLC communication module of the energy meter is to connect the HPLC communication module of the energy meter with the electric measuring equipment, so that the electric measuring equipment can power on the HPLC communication module of the energy meter and perform shield communication detection.

[0003] A Chinese patent discloses an automatic shield crimping device for crimping the HPLC communication module of an electric energy meter (authorization announcement number is CN2147540626U). The device has a simple structure and can realize the comprehensiveness of the detection function items of the HPLC communication module of the electric energy meter. The connection components are integrated into one design, saving time, effort and money.

[0004] According to the above comparative cases, when the above device is in use, after the tray is transported into place on the conveyor line, the pressing assembly and the crimping assembly operate simultaneously, and the HPLC module on the tray is crimped and tested through the ejector pin. This requires ensuring that the HPLC module is placed on the tray facing the ejector pin, otherwise the ejector pin will be misaligned with the pin of the HPLC module, which will not only make the HPLC module unable to be connected to the ejector pin, but also cause damage to the probe or HPLC module. However, the above device cannot detect whether the HPLC module and the ejector pin are intact before the ejector pin is connected to the pin of the HPLC module, making it difficult to ensure the normal progress of the subsequent detection process. Summary of the invention

[0007] Further, the connecting mechanism includes a mounting frame, a first electric cylinder, a second electric cylinder, a connecting assembly, a mounting seat, a detection assembly and a guiding assembly, the first electric cylinder and the second electric cylinder are both fixedly connected to one end of the mounting frame, the connecting assembly is fixedly connected to the surface of the second electric cylinder, the mounting seat is fixedly connected to the other end of the mounting frame, a circular hole is provided on the top of the mounting seat, the top of the connecting assembly penetrates into the inside of the circular hole, a sliding cavity connected to the circular hole is provided inside the mounting seat, a mounting cavity connected to the sliding cavity is provided on the surface of the mounting seat, the detection assembly is installed in the inside of the sliding cavity, one end of the detection assembly penetrates to the outside of the mounting cavity, the guiding assembly is installed on the surface of the detection assembly, and one end of the guiding assembly penetrates through the sliding cavity and the circular hole in sequence and extends to the outside of the circular hole;

[0008] Wherein, the connecting assembly comprises a base and an ejector pin, the base is fixedly connected to the surface of the second electric cylinder, and the ejector pin is fixedly connected to the surface of the base;

[0009] Wherein, the detection component includes an installation box, a single-chip microcomputer, a photosensitive sensor, a DC power supply, a light-emitting diode, two fixed conductive strips and a movable conductive strip, the installation box is fixedly connected to the surface of the installation seat, the single-chip microcomputer, the photosensitive sensor, the DC power supply and the light-emitting diode are all fixedly connected to the inside of the installation box, the photosensitive sensor and the DC power supply are both electrically connected to the single-chip microcomputer, the cathode of the light-emitting diode is electrically connected to the negative pole of the DC power supply, the two fixed conductive strips are respectively electrically connected to the anode of the light-emitting diode and the positive pole of the DC power supply, the opposite ends of the two fixed conductive strips both penetrate the installation cavity and extend to the inside of the sliding cavity, the movable conductive strip is fixedly connected to the surface of the guide component, the movable conductive strip is arranged above the fixed conductive strip, and the length of the movable conductive strip is greater than the spacing between the two fixed conductive strips;

[0010] Among them, the guiding assembly comprises a sliding frame, a circular tube, a connecting rod, a circular ring and a first spring, the sliding frame is slidably connected to the inside of the sliding cavity, and the sliding frame is arranged on the two fixed conductive strips, the circular tube is fixedly connected to one end of the sliding frame, and one end of the circular tube passes through the outside of the circular hole, the connecting rod is slidably connected to the inside of the sliding frame, both ends of the connecting rod pass through the outside of the sliding frame, one end of the connecting rod is fixedly connected to the movable conductive strip, the circular ring is fixedly connected to the other end of the connecting rod, and one end of the circular ring passes through the inside of the circular hole, the inner diameters of the circular tube and the circular ring are the same as the diameter of the ejector pin, the axial center lines of the circular tube, the circular ring and the ejector pin all coincide with each other, and the first spring is sleeved on the surface of the circular tube, and the two ends of the first spring are respectively in contact with the mounting seat and the circular tube.

[0011] In one of the embodiments, when the first electric cylinder is extended into place, the staff can determine whether the mounting seat is tightly fitted with the inner wall of the interface of the HPLC communication module of the energy meter by judging whether the light-emitting diode is emitting light, and then determine whether the HPLC communication module of the energy meter is correctly placed. This not only enables the staff to timely and accurately check the HPLC communication module of the energy meter at the corresponding position, but also reduces the probability of damage to the ejector pin due to incorrect crimping. After the mounting seat is installed in place, the mounting seat and the round tube cooperate with the electromagnetic wave shielding paint to form a shielding space, and can separate a pin in the interface of the HPLC communication module of the energy meter from the corresponding ejector pin. Being arranged in this space can reduce the probability of electromagnetic interference generated by pins in the interface of the HPLC communication module of adjacent electric energy meters or adjacent ejector pins, thereby improving the stability and accuracy of subsequent tests; in the process of the ejector pin rising, the guide component can synchronously detect whether the ejector pin is bent, and after the bent ejector pin contacts the guide component, the bent ejector pin can be blocked by the guide component and disconnect the path of the light-emitting diode, causing it to stop emitting light and stopping the ejector pin from continuing to rise, which not only enables the staff to timely and accurately check the connection components at the corresponding positions, but also reduces the probability of damaging the pins in the interface of the HPLC communication module of the electric energy meter due to the crimping of the ejector pin in an incorrect form.

[0012] Furthermore, the surface of the installation box is coated with light-shielding paint.

[0013] In one embodiment, this can reduce the amount of external light that enters the interior of the mounting box, thereby reducing interference with the light-sensitive sensor.

[0014] Furthermore, the surfaces of the mounting seat and the circular tube are coated with electromagnetic wave shielding paint.

[0015] In one embodiment, the mounting base and the round tube cooperate to form a porous shielding space, which can reduce the probability of electromagnetic interference between pins in the interface of an adjacent electric energy meter HPLC communication module or adjacent ejector pins, thereby improving the stability and accuracy of subsequent tests.

[0016] Furthermore, a positioning ring is fixedly connected to the surface of the circular tube, one end of the first spring is in contact with the positioning ring, and the diameter of the positioning ring is greater than the diameter of the first spring.

[0017] In one embodiment, this can confine the first spring to the surface of the tube and prevent the first spring from falling off.

[0018] Furthermore, one end of the mounting seat is provided with an annular groove connected to the circular hole, and the other end of the first spring is in contact with the annular groove; the diameter of the annular groove is the same as the diameter of the positioning ring, and the height ratio of the annular groove to the positioning ring is one to five.

[0019] In one embodiment, this not only ensures that the round tube can be completely immersed in the round hole to ensure that the movable conductive strip can effectively contact the fixed conductive strip, but also leaves enough expansion space for the first spring to avoid the possibility of the first spring being damaged due to excessive pressure.

[0020] Furthermore, a positioning sleeve is slidably connected inside the sliding frame, and the positioning sleeve is fixedly connected to the surface of the connecting rod. The horizontal cross-sectional diameter of the positioning sleeve is larger than the horizontal cross-sectional diameter of the contact portion between the sliding frame and the connecting rod.

[0021] In one of the embodiments, this can limit the sliding trajectory of the connecting rod, further ensuring that the movable conductive strip can effectively contact the fixed conductive strip while the round tube is completely immersed in the round hole.

[0022] Furthermore, the shapes of the horizontal cross-section of the inner side of the sliding frame and the horizontal cross-section of the positioning sleeve are both matching rectangles.

[0023] In one embodiment, this can prevent the connecting rod from rotating to ensure that the axis of the ring always coincides with the axis of the tube.

[0024] Furthermore, a second spring is sleeved on the surface of the connecting rod, and two ends of the second spring are respectively in contact with the sliding frame and the positioning sleeve, and the second spring is always in a compressed state.

[0025] In one of the embodiments, the second spring can always apply a downward pressure to the positioning sleeve to prevent the ring and the movable conductive strip from shaking during the process of the document, so as to improve the accuracy of the detection.

[0026] Furthermore, the pressing mechanism includes an electric cylinder and a pressure plate, the electric cylinder is fixedly connected to the surface of the carrier frame, one end of the electric cylinder penetrates to the outside of the carrier frame, and the pressure plate is fixedly connected to one end of the electric cylinder.

[0027] In one of the embodiments, this can press down and position the HPLC communication module of the electric energy meter in the positioning tray in advance, thereby preventing the HPLC communication module of the electric energy meter from moving during the crimping process between the HPLC communication module and the ejector pin, thereby improving the success rate of crimping between the HPLC communication module and the ejector pin.

[0028] The shielding crimping device for crimping the HPLC communication module of the above-mentioned electric energy meter, when the first electric cylinder is extended into place, the staff can judge whether the mounting seat is tightly fitted with the inner wall of the interface of the HPLC communication module of the electric energy meter by judging whether the light-emitting diode is emitting light, and then judge whether the HPLC communication module of the electric energy meter is correctly placed, which not only enables the staff to timely and accurately check the HPLC communication module of the electric energy meter at the corresponding position, but also reduces the probability of damage of the ejector pin due to incorrect crimping, and after the mounting seat is installed in place, the mounting seat and the round tube cooperate with the electromagnetic wave shielding paint to form a shielding space, and a certain pin in the interface of the HPLC communication module of the electric energy meter and the corresponding ejector pin can be separately arranged in the space, which can reduce the probability of electromagnetic interference between the pins in the interface of the HPLC communication module of the adjacent electric energy meter or the adjacent ejector pins, thereby improving the stability and accuracy of subsequent tests;

[0029] During the rising process of the ejector pin, the guide component can synchronously detect whether the ejector pin is bent, and after the bent ejector pin contacts the guide component, the bent ejector pin can be blocked by the guide component and disconnect the path of the light-emitting diode, causing it to stop emitting light and stop the ejector pin from continuing to rise. This not only enables the staff to promptly and accurately check the connection components at the corresponding positions, but also reduces the probability of damaging the pins in the interface of the HPLC communication module of the energy meter due to the incorrect shape of the ejector pin.

[0048] Combine the following Figure 1 - Fig.10 The invention describes a shield crimping device for crimping an HPLC communication module of an electric energy meter.

[0049] In one embodiment, a shielding crimping device for crimping an HPLC communication module of an electric energy meter includes a carrier 100 and a host computer. An electric slide 200 is fixedly connected to the surface of the carrier 100. A positioning tray 300 is installed on the surface of the electric slide 200. A pressing mechanism 400 is fixedly connected to the surface of the carrier 100. A connecting mechanism 500 is installed on the inner side of the carrier 100. The host computer is a PC. The host computer establishes a connection with a single-chip microcomputer 562 through asynchronous communication. The host computer is electrically connected to a pin 542 through an interface converter. The staff can compile a program for testing the HPLC communication module of the electric energy meter in advance in the host computer. When the pin 542 is connected to the pin in the interface of the HPLC communication module of the electric energy meter, the host computer can establish a connection with the HPLC communication module of the electric energy meter through the interface converter and the pin 542, and then perform the test operation normally.

[0050] The pressing mechanism 400 includes an electric cylinder 410 and a pressing plate 420 . The electric cylinder 410 is fixedly connected to the surface of the carrier 100 . One end of the electric cylinder 410 penetrates to the outside of the carrier 100 . The pressing plate 420 is fixedly connected to one end of the electric cylinder 410 .

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the connection mechanism 500 includes a mounting frame 510, one end of which is fixedly connected to the first electric cylinder 520 and the second electric cylinder 530, the surface of the second electric cylinder 530 is fixedly connected to the connection component 540, the other end of the mounting frame 510 is fixedly connected to the mounting seat 550, the top of the mounting seat 550 is provided with a circular hole 551, the top of the connection component 540 penetrates into the inside of the circular hole 551, the inside of the mounting seat 550 is provided with a sliding cavity 552 communicating with the circular hole 551, the surface of the mounting seat 550 is provided with a mounting cavity 553 communicating with the sliding cavity 552, the inside of the sliding cavity 552 is provided with a detection component 560, one end of the detection component 560 penetrates to the outside of the mounting cavity 553, the surface of the detection component 560 is installed with a guide component 570, one end of the guide component 570 penetrates the sliding cavity 552 and the circular hole 551 in sequence and extends to the outside of the circular hole 551;

[0052] When the positioning tray 300 equipped with the HPLC communication module of the energy meter is moved to the preset position between the pressing mechanism 400 and the connecting mechanism 500 by the electric slide 200, the upper computer controls the electric cylinder 410 to extend the specified length according to the preset program, and the electric cylinder 410 drives the pressing plate 420 to move down the specified distance until the pressing plate 420 presses the top of the HPLC communication module of the energy meter. When the electric cylinder 410 finishes running, the upper computer controls the first electric cylinder 520 to extend according to the preset program, and the first electric cylinder 520 drives the mounting frame 510 to rise, and the mounting frame 510 drives the mounting seat 550 to rise, and the mounting seat 550 penetrates into the interface of the HPLC communication module of the energy meter and contacts the inner wall of the interface of the HPLC communication module of the energy meter.

[0053] During the process of the mounting seat 550 rising, the top of the round tube 572 contacts the inner wall of the interface of the HPLC communication module of the electric energy meter in advance. During the subsequent process of the mounting seat 550 rising, the round tube 572 descends relative to the mounting seat 550, and the round tube 572 drives the sliding frame 571 to descend relative to the mounting seat 550 along the sliding cavity 552. The sliding frame 571 drives the movable conductive strip 567 to descend relative to the mounting seat 550. When the mounting seat 550 rises to the specified position, the specific situation is as follows:

[0054] ① When the HPLC communication module of the energy meter is properly placed inside the positioning tray 300, the round tube 572 is completely immersed in the round hole 551, and the movable conductive strip 567 is just in contact with the two fixed conductive strips 566. Since the cathode of the light-emitting diode 565 is electrically connected to the negative electrode of the DC power supply 564, the anode of the light-emitting diode 565 is effectively electrically connected to the positive electrode of the DC power supply 564 through the two fixed conductive strips 566 and the movable conductive strip 567. At this time, the DC power supply 564 can provide the light-emitting diode with a positive connection. 565 is powered normally, the light emitting diode 565 emits light, and the light sensitive sensor 563 detects the light signal and transmits the signal to the single chip computer 562. The single chip computer 562 controls the second electric cylinder 530 to shorten according to the preset instruction, and feeds back the corresponding signal to the host computer. The second electric cylinder 530 drives the base 541 to move upward, and the base 541 drives the ejector pin 542 to pass through the circular hole 551, the circular ring 574 and the circular tube 572 in sequence and press them together with the pins in the interface of the HPLC communication module of the electric energy meter, and then the detection operation is carried out normally;

[0055] ② When the HPLC communication module of the electric energy meter is tilted and placed inside the positioning tray 300, the interface between the mounting seat 550 and the HPLC communication module of the electric energy meter is in a non-aligned state. Even if the mounting seat 550 is inserted into the interface of the HPLC communication module of the electric energy meter, the mounting seat 550 cannot perfectly fit on the inner wall of the interface of the HPLC communication module of the electric energy meter. At this time, there is a gap between the mounting seat 550 and the inner wall of the interface of the HPLC communication module of the electric energy meter, and the round tube 572 cannot perfectly sink into the round hole 551. At this time, the movable conductive strip 567 is still in a misaligned state with the two fixed conductive strips 566, and the light-emitting diode 565 cannot emit light normally. The single-chip computer 562 does not feedback corresponding information to the upper computer within the specified time, and the second electric cylinder 530 does not drive the ejector pin 542 to be inserted into the interface of the HPLC communication module of the electric energy meter through the base 541. This not only enables the staff to timely and accurately check the HPLC communication module of the electric energy meter at the corresponding position, but also reduces the probability of the ejector pin 542 being damaged due to incorrect crimping.

[0056] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting assembly 540 includes a base 541 and a ejector pin 542 , the base 541 is fixedly connected to the surface of the second electric cylinder 530 , and the ejector pin 542 is fixedly connected to the surface of the base 541 ;

[0057] It should be noted that the second electric cylinder 530, the connecting assembly 540 and the mounting seat 550 are used in combination, and the number and arrangement of the second electric cylinder 530, the connecting assembly 540 and the mounting seat 550 need to be the same as the number and arrangement of the HPLC communication module of the electric energy meter, the number and arrangement of the ejector pins 542 need to be the same as the number and arrangement of the pins in the interface of the HPLC communication module of the electric energy meter, the round hole 551, the sliding cavity 552, the movable conductive strip 567 and the guide assembly 570 are all used in combination, and the round hole 5 51. The number and arrangement of the slide cavity 552, the movable conductive strips 567 and the guide assembly 570 are the same as the number and arrangement of the ejector pins 542. If the number of the movable conductive strips 567 is n (n is a positive integer), the number of the fixed conductive strips 566 must be n+1, and the opposite ends of two adjacent fixed conductive strips 566 pass through the interior of the same slide cavity 552, and one end of the first and last fixed conductive strips 566 are electrically connected to the anode of the light-emitting diode 565 and the positive pole of the DC power supply 564, respectively.

[0058] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the detection component 560 includes a mounting box 561, a single-chip microcomputer 562, a photosensor 563, a DC power supply 564, a light-emitting diode 565, two fixed conductive strips 566 and a movable conductive strip 567. The mounting box 561 is fixedly connected to the surface of the mounting base 550, the single-chip microcomputer 562, the photosensor 563, the DC power supply 564 and the light-emitting diode 565 are all fixedly connected to the inside of the mounting box 561, the photosensor 563 and the DC power supply 564 are all electrically connected to the single-chip microcomputer 562, and the cathode of the light-emitting diode 565 is connected to the The negative pole of the DC power supply 564 is electrically connected, and the two fixed conductive strips 566 are electrically connected to the anode of the light-emitting diode 565 and the positive pole of the DC power supply 564 respectively. The opposite ends of the two fixed conductive strips 566 pass through the installation cavity 553 and extend to the interior of the sliding cavity 552. The movable conductive strip 567 is fixedly connected to the surface of the guide component 570. The movable conductive strip 567 is arranged above the fixed conductive strip 566. The length of the movable conductive strip 567 is greater than the spacing between the two fixed conductive strips 566. The surface of the installation box 561 is coated with a light-shielding paint.

[0059] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the guide assembly 570 includes a slide frame 571, a round tube 572, a connecting rod 573, a ring 574 and a first spring 575.

The round tube 572 is fixedly connected to one end of the slide frame 571, and one end of the round tube 572 passes through the outside of the round hole 551. The connecting rod 573 is slidably connected to the inside of the slide frame 571, and both ends of the connecting rod 573 pass through the outside of the slide frame 571.

The horizontal cross-sectional diameter of the positioning sleeve 577 is larger than the horizontal cross-sectional diameter of the contact portion between the sliding frame 571 and the connecting rod 573. The horizontal cross-sectional shapes of the inner side of the sliding frame 571 and the horizontal cross-sectional shapes of the positioning sleeve 577 are both matching rectangles. A second spring 578 is sleeved on the surface of the connecting rod 573, and the two ends of the second spring 578 are respectively in contact with the sliding frame 571 and the positioning sleeve 577, and the second spring 578 is always in a compressed state.

[0060] During the rise of ejector pin 542, annular ring 574 can detect in real time whether ejector pin 542 is bent. When ejector pin 542 is bent, the axis of ejector pin 542 is misaligned with the axis of annular ring 574. During the subsequent rise of ejector pin 542, ejector pin 542 drives annular ring 574 to rise together, annular ring 574 drives connecting rod 573 to rise, and connecting rod 573 drives movable conductive strip 567 to separate from fixed conductive strip 566. At this time, the path between DC power supply 564 and light-emitting diode 565 is closed. The light-emitting diode 565 stops emitting light, the photosensor 563 cannot detect the light signal, and the single-chip computer 562 stops the second electric cylinder 530 from moving upward according to the preset program, and stops sending signals to the upper computer. At this time, the staff can promptly detect the obstruction of the connecting component 540 at the corresponding position, which not only enables the staff to promptly and accurately check the connecting component 540 at the corresponding position, but also reduces the probability of the incorrect shape of the ejector pin 542 crimping and damaging the pins in the interface of the HPLC communication module of the energy meter.

[0061] It should be noted that the electric slide 200, electric cylinder 410, first electric cylinder 520, second electric cylinder 530, ejector pin 542, single-chip microcomputer 562, photosensor 563, DC power supply 564, light-emitting diode 565, interface converter and host computer in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the electric slide 200, electric cylinder 410, first electric cylinder 520, second electric cylinder 530, ejector pin 542, single-chip microcomputer 562, photosensor 563 and host computer can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
