Description

Technical Field

[0001] This application relates to the field of electricity meter manufacturing equipment technology, and more particularly to a main control board programmer for smart meters. Background Technology

[0002] A smart meter is a new type of meter that uses modern microelectronics, sensing technology, and smart IC card technology to measure electricity consumption and transmit and settle electricity transactions. In the production process of a smart meter, software programs need to be programmed into its main control board (circuit board). Current programming processes typically involve a programmer connecting to the contacts of the main control board via a programming connector. To improve production efficiency, multiple programmers are usually used to program multiple main control boards simultaneously. These programmers are typically arranged linearly in the left-right direction and fixed on the programmer's bracket.

[0003] However, when multiple programmers are arranged side-by-side on the base, their overall width exceeds the width of the base. This increases the space occupied by the programmers in the left and right directions, especially when the programmers are stored on the shelf in an idle state, their large horizontal projection area occupies a lot of space, resulting in a waste of storage resources.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a main control board programmer for smart meters, which solves the problem that the linear arrangement of multiple programmers in the prior art results in a large overall width and a large space occupation during storage.

[0006] The technical solution of this application is as follows: On the one hand, this application proposes a main control board programmer for smart meters, including: a base, a vertical frame on the base, and multiple programming positions distributed horizontally on the base, the programming positions being used to limit the main control board to be programmed; The programming rack is rotatably mounted on a vertical frame. Multiple programmers are mounted on the programming rack, and the programming connectors of the multiple programmers are mounted on the base and correspond to the programming positions respectively. The pressing mechanism is movably mounted on the vertical frame. The main control board to be programmed is electrically connected to the programming connector through the pressing mechanism. The burning rack has an unfolded state and a folded state by flipping; In the unfolded state, the left and right ends of the burning machine frame protrude from both sides of the base in the left and right directions, respectively; When folded, the left and right ends of the burner rack are aligned with the left and right center lines.

[0007] Optionally, the burning rack includes: a first rack body and a second rack body, which are respectively hinged to the left and right sides of the vertical frame; The first frame and the second frame can be flipped independently, or the first frame and the second frame can be flipped synchronously in conjunction.

[0008] Optionally, when the first frame and the second frame are linked and rotate synchronously, a first gear set is provided at the end of the first frame and a second gear set is provided at the end of the second frame, and the first gear set and the second gear set mesh with each other.

[0009] Optionally, the main control board programmer also includes a main power switch, which is electrically connected to multiple programmers and is used to turn on the power to multiple programmers. The burner rack is connected to a locking mechanism, which moves by flipping the burner rack to press or release the main power switch.

[0010] Optionally, the locking mechanism includes a driven gear that rotates by the flipping of the burner frame; A rack meshes with a driven gear and moves in the left-right direction by being driven by the driven gear. The pressing part is provided on the rack, and the main power switch is pressed or released by the movement of the rack.

[0011] Optionally, a first locking platform is fixedly installed on the pressing mechanism; The rack is also equipped with a first locking element. The first locking element moves closer to the first locking platform to block the downward movement of the first locking platform, or moves away from the first locking platform to avoid it.

[0012] Optionally, the rack is also provided with a flexible retainer, which abuts against the burner rack by the movement of the rack to limit the folding state of the burner rack; The elastic locking components include: a locking spring and a locking gear, the locking gear engaging the burner frame via the elastic force of the locking spring; The elastic force generated by the locking spring is used to overcome the weight of the burner rack and limit the folding state of the burner rack.

[0013] Optionally, at least two rows of programmers are provided on the first rack and the second rack, and the two rows of programmers are arranged in the vertical direction.

[0014] Optionally, both the first frame and the second frame are telescopically extendable in the left and right directions.

[0015] Optionally, the programming connector is fixedly mounted on the base; The base includes a movable support member, multiple programming positions are disposed on the support member, and through holes are provided through the programming positions; The carrier component moves the main control board to be programmed by pressing down the pressing mechanism, so that the programming connector passes through the through hole and abuts against the contacts of the main control board to make an electrical connection.

[0016] The beneficial effects of the main control board programmer for smart meters provided in this application are at least as follows: By setting a flip-up programming rack, it can have both unfolded and folded states. In the unfolded state, the programming rack can perform programming operations normally; in the folded state, the left and right ends of the programming rack retract inward, significantly reducing the overall width of the device and ensuring it does not exceed the width range of the base. This greatly saves the horizontal space occupied by the device when not in use, improving storage utilization. In addition, by setting a first rack body and a second rack body, and allowing for independent or linked flipping, flexible operation is provided. Linked flipping is achieved through gear meshing, which is simple to operate; driving one side drives the other side synchronously, improving the convenience and synchronization of operation. Moreover, by setting a locking mechanism linked to the programming rack, intelligent operation and equipment safety are achieved. When the programming rack is in the unfolded state, the locking mechanism automatically turns on the main power switch, and the device is powered on and ready; when the programming rack is folded, the main power switch is turned off, ensuring that the device is powered off when stored, improving safety. By cooperating with the first locking mechanism and the first locking plate, a safe locking system is achieved during the burning process. When the equipment is idle, the locking mechanism simultaneously locks the pressing mechanism to prevent accidental pressing down and damage to the equipment. The use of elastic locking components provides reliable limiting and holding force for the folded state of the burning rack. The elasticity of the locking springs can overcome the weight of the burning rack itself, ensuring its stable holding after folding and preventing accidental unfolding due to gravity, further guaranteeing storage safety. By arranging multiple rows of burners on the rack body, more burning positions can be integrated into a limited space, improving the burning efficiency and space utilization of the equipment.

[0022] like Figure 1 , Figure 2 As shown, this embodiment proposes a main control board programmer for smart meters, used to program the main control board (circuit board) of a smart meter. The main control board programmer mainly includes: a base 100, a vertically mounted frame 200 on the base 100, a pressing mechanism 300, and a programmer frame 400. The base 100 can be rectangular, with a front-back direction and a left-right direction in the horizontal direction. Multiple programming positions 111 can be provided on the base 100, distributed horizontally, for example, arranged in a rectangular row. The programming positions 111 are used to limit the main control board to be programmed. A programming rack 400 is rotatably mounted on a vertical frame 200. Multiple programmers 500 are mounted on the programming rack 400. The programming connectors 510 of the multiple programmers 500 are mounted on a base 100 and correspond to programming positions 111. The programmers 500 are existing programming devices. By aligning the programming connectors 510 with contacts on the main control board to be programmed, an electrical connection is established with the main control board, and the preset program is programmed (copied) into the main control board, enabling the main control board to perform its corresponding functions. A pressing mechanism 300 is movably mounted on the vertical frame 200. The main control board to be programmed is electrically connected to the programming connectors 510 by pressing down on it through the pressing mechanism 300. For example, before programming, the main control board is placed in programming position 111, at which point there is a certain vertical gap between the main control board and the programming connectors 510. The pressing mechanism 300 presses down on the main control board, thereby connecting the main control board with the programming connectors 510. The burning rack 400 is in an unfolded state by flipping (e.g. Figure 1 (as shown) and folded state (as shown) Figure 2 (As shown). In the unfolded state, the left and right ends of the burner rack 400 protrude from both sides of the base 100 in the left and right directions, respectively. In the folded state, the left and right ends of the burner rack 400 move closer to the left and right center lines.

[0023] like Figure 1 As shown, in the specific structure, a programming rack 400 is rotatably mounted on the upper part of the vertical frame 200 via a pivot. Multiple programmers 500 are fixedly mounted on the programming rack 400. These programmers 500 are connected to programming connectors 510 via cables, with the programming connectors 510 located on the base 100 and below the programming positions 111. Each programming connector 510 corresponds to a programming position 111. The programming rack 400 can be rotated about a pivot extending in the front-rear direction, thus having an unfolded state and a folded state. Figure 1 As shown, in the unfolded state, the burning rack 400 unfolds horizontally, with its left and right ends clearly protruding from the left and right sides of the base 100. At this time, the multiple burners 500 located on the burning rack 400 are arranged in the left and right direction, ready for burning operations. Figure 2As shown, in the folded state, the burner rack 400 flips upwards, with its left and right ends converging towards the center line (the middle position in the left-right direction), reducing the width of the entire device to within the width of the base 100 for easy storage. This embodiment cleverly solves the problem of large storage space occupied when multiple burners 500 are placed on a single base 100 by using a flip-up burner rack 400. When in operation, the burner rack 400 is unfolded, ensuring sufficient operating space; as... Figure 2 As shown, the burner rack can be folded 400 degrees when not in use, which greatly saves the horizontal space occupied by the equipment when it is not in use, improves the utilization rate of the warehouse, and saves valuable workshop or warehouse space.

[0024] like Figure 1 , Figure 4 As shown, in some embodiments, the base 100 includes a support member 110 that is movably disposed in the vertical direction. A programming position 111 is formed on the support member 110. The support member 110 is connected to the base 100 below it via an elastic guide post 120, allowing the support member 110 to move downwards under pressure and return to its original position away from the base 100 when not under pressure. A programming connector 510 is fixedly disposed on the base 100 and located below the support member 110. The programming connector 510 can be multiple elastic pins. Each programming position 111 has a through hole. During the downward movement of the support member 110, the programming connector 510 can pass through the through hole and contact the contacts of the main control board located in the programming position 111. Therefore, when the main control board is placed on the programming position 111 of the support member 110, the pressing mechanism 300 moves downwards, pushing the support member 110 downwards as well. As the carrier 110 moves downward, the fixed programming connector 510 passes through the through hole and abuts against the contact at the bottom of the main control board, thereby achieving electrical connection. The programmer 500 can then perform normal programming. After programming is completed, the pressing mechanism 300 retracts, causing the carrier 110 to reset under the elastic force of the elastic guide post 120. The upward-moving carrier 110 carries the main control board away from the programming connector 510, separating the programmed main control board from the programming connector 510.

[0025] like Figure 1 , Figure 3 , Figure 5 As shown, in some embodiments, the programming rack 400 consists of a first rack body 410 and a second rack body 420. For example, the first rack body 410 and the second rack body 420 are respectively hinged to the left and right sides of the vertical frame 200 via a hinge structure, and can be independently flipped upwards. Multiple programmers 500 are provided on both the first rack body 410 and the second rack body 420 on the left and right sides. During the flipping process, the first rack body 410 and the second rack body 420 on the left and right sides can be flipped independently, or they can be flipped in tandem.

[0026] like Figure 1 , Figure 3 , Figure 5 As shown, in the specific structure in which the first frame 410 and the second frame 420 can be linked and rotated: a first gear set 411 is fixedly installed at the end of the first frame 410 near the rotating shaft, and a second gear set 421 is fixedly installed at the corresponding position of the second frame 420. The first gear set 411 and the second gear set 421 mesh with each other. When the first frame 410 is driven to rotate, the second frame 420 will simultaneously rotate in the opposite direction through gear transmission, thereby realizing the linked folding or unfolding of the two frames. The first gear set 411 and the second gear set 421 can be semi-circular gears, or they can be gears concentrically arranged with the first frame 410 or the second frame 420 via the rotating shaft.

[0027] like Figure 1 , Figure 3 , Figure 5 As shown, for example, the distance between the first frame body 410 and the second frame body 420 is relatively large. The first gear set 411 can be two meshing gears. The first gear is fixed to the first frame body 410, and the second gear is rotatably mounted on the vertical frame 200 and meshes with the first gear. Correspondingly, the second gear set 421 is also provided with two meshing gears, so as to cooperate with the first gear set to realize the synchronous rotation of the first frame body 410 and the second frame body 420.

[0028] For example, if the distance between the first frame and the second frame is small (not shown in the figure), the first gear set can be a single gear that is fixed to the first frame; the corresponding second gear set also has a single gear, which cooperates with the first gear set to achieve synchronous rotation of the first frame and the second frame.

[0029] The different structures described above utilize two different frame flipping methods, increasing the equipment's flexibility. In particular, the linkage system, through a simple gear meshing structure, enables synchronous movement of both frames, allowing operators to fold or unfold the equipment by operating only one side, thus improving operational convenience and efficiency.

[0030] like Figure 3 , Figure 5 , Figure 6As shown, in some embodiments, the entire main control programmer is in a non-working state when folded, which enhances power safety control. Specifically, a main power switch 520 is installed on the vertical frame 200. This main power switch is electrically connected to all programmers 500 and controls the total power supply to the programmers 500. In the unfolded state, the main power switch 520 is triggered, allowing all programmers 500 to be powered on normally. In the folded state, the main power switch 520 is turned off, disconnecting the power supply to all programmers 500. This prevents the programmers 500 from starting even if other control buttons on the programmers 500 are accidentally pressed. To trigger and turn off the main power switch 520, a locking mechanism 600 is connected to the programmer rack 400. When the programmer rack 400 flips from the folded state to the unfolded state, it moves the locking mechanism 600, pressing the main power switch 520 and turning it on, thus powering on all programmers 500. Conversely, when the programmer rack 400 flips from the unfolded state to the folded state, the locking mechanism 600 releases the main power switch 520, turning it off and cutting off power to all programmers 500.

[0031] like Figure 3 , Figure 6 , Figure 7 As shown, the locking mechanism 600 further includes a rotatable driven gear 610, a rack 620, and a pressing part 630. The driven gear 610 is rotatably mounted on the vertical frame 200 and meshes with the first gear set 411 of the first frame 410 or the second gear set 421 of the second frame 420 of the burner rack 400. For example, the driven gear 610 meshes with the first gear set 411 on the first frame 410 and is located below the first gear set 411. Below the driven gear 610, it meshes with the rack 620. A guide rail extending in the left-right direction is also provided below the vertical frame 200. The rack 620 can slide in the left-right direction within the guide rail. The pressing part 630 is fixed to the end of the rack 620. The main power switch 520 is located on the movement trajectory of the pressing part 630. When the burner rack 400 is unfolded, the first frame body 410 rotates from a vertical to a horizontal position, causing the first gear set 411 to drive the driven gear 610 to rotate, which in turn drives the rack 620 to move outward in the left-right direction. The moving pressing part 630 presses the main power switch 520. When the burner rack 400 is folded, the driven gear 610 drives the rack 620 to move inward in the left-right direction, thereby disengaging the pressing part 630 from the main power switch 520. This achieves automation and safety in equipment operation. The burner rack 400 is powered on when unfolded and powered off when folded, avoiding the tedious operation of manually plugging and unplugging the power supply and preventing accidental power-on when the equipment is in the stored (folded) state, thus eliminating safety hazards.

[0032] like Figure 6 , Figure 7 As shown, the pressing part 630 may be provided with a pressing slope 631. During the process of the pressing part 630 moving toward the main power switch 520, the pressing slope 631 contacts the main power switch 520, so that the main power switch 520 can be slowly pressed, thus making the pressing process more stable.

[0033] like Figure 4 , Figure 5 , Figure 6 As shown, based on the above structure, a first locking platform 321 is fixedly installed on the pressing mechanism 300. The first locking platform 321 can move up and down with the pressing mechanism 300. In the specific structure, the pressing mechanism 300 specifically includes: a force-applying part 310, a pressing part 320, a vertical guide rail 330, and multiple lower tops 340. The force-applying part 310 can be a push-pull quick clamp (manual) or a cylinder (automatic). The force-applying part 310 is installed on the bracket and located above the support plate. The pressing part 320 can be a pressing plate. The pressing plate is horizontally fixedly connected to the push rod of the force-applying part 310 and located above the support plate, so that it moves toward or away from the support plate by being driven by the force-applying part 310. A vertical guide rail 330 is mounted on the base 100 along the vertical direction. A pressing part 320 is slidably mounted on the vertical guide rail 330. During the pushing process of the pressing part 320, the vertical guide rail 330 guides the pressing part 320, allowing it to slide stably up and down. A lower top 340 is mounted along the vertical direction, with its upper end fixed to the lower surface of the pressing part 320. Multiple lower tops 340 are spaced apart on the pressing part 320 and abut against different positions on the main control plate of the support plate. During the downward pushing of the pressing part 320, the multiple lower tops 340 move downward and abut against the main control plate, fixing the main control plate within the limiting cavity. Further downward pushing causes the entire support member 110 to move downward. Additionally, a return spring is sleeved on the vertical guide rail 330, located below the pressing part 320. This return spring allows the pressing part 320 to be pushed back to its initial position after the downward pressure is released. The first locking plate 321 is located at the rear end of the pressing part 320, for example, protruding towards the rear end and extending above the rack 620.

[0034] like Figure 4 , Figure 5 , Figure 6As shown, a first locking member 640 is also fixedly mounted on the rack 620. When the burner rack 400 is unfolded, the rack 620 moves and drives the pressing part 630 to move to the energized position when the main power switch 520 is pressed. The first locking member 640 is driven by the rack 620 to deviate from the space below the first locking platform 321, thereby avoiding the downward movement of the first locking platform 321. When the burner rack 400 is folded, after the rack 620 drives the pressing part 630 to move and disengage from the main power switch 520, the first locking member 640 is driven by the gear to be located in the space below the first locking platform 321 and can abut against the bottom of the first locking platform 321 to lock the first locking platform 321. At this time, if the pressing mechanism 300 moves downward, the first locking platform 321 will be blocked by the first locking piece 640 and cannot move down. This actually constitutes an interlock, that is, the pressing mechanism 300 can only be allowed to press down after the burning machine rack 400 is fully unfolded and locked (powered on).

[0035] like Figure 4 , Figure 5 , Figure 6 As shown, the upper surface of the first locking member 640 further includes an inclined locking surface 641 and a locking position surface 642. The locking position surface 642 is a horizontal surface, and the inclined locking surface 641 is disposed at the end of the locking surface 642 facing the first locking platform 321. The inclined locking surface 641 is gradually inclined downward along the direction of movement toward the first locking platform 321. In this way, when the first locking member 640 moves with the rack 620, the inclined locking surface 641 first moves to the lower part of the first locking platform 321 and can contact the first locking platform 321 to guide the movement, thereby causing the locking surface 642 to move to the lower part of the first locking platform 321 later, so as to lock the first locking platform 321 more stably.

[0036] In some embodiments, a folding retainer can be provided to make the programming rack 400 more stably held in the folded state. When the programming rack 400 is in the folded state, the first rack body 410 and the second rack body 420, which are in a vertical state, will not fall to a horizontal position due to their own gravity, thus ensuring that the main control board programming machine is stably held in the folded state when idle. The specific solution is as follows: like Figure 4 , Figure 5 , Figure 6As shown, in one structure, a force-enhancing pad 643 is provided on the first card 640, for example, on the inclined card surface 641 and / or the card slot surface 642. Correspondingly, micro-tooth or other concave-convex microstructures can be provided on the lower surface of the first locking platform 321. When the lower surface of the first card 640 abuts against the lower surface of the first locking platform 321, the lower surface of the first locking platform 321 contacts the force-enhancing pad 643, increasing the frictional force. As long as this frictional force is sufficient to overcome the gravity of the burning machine frame 400 (first frame body 410 and / or second frame body 420), the folding state of the burning machine frame 400 can be limited. Therefore, when the first frame body 410 and the second frame body 420 are in the folded vertical state, the frictional force is large enough to prevent the first frame body 410 and the second frame body 420 from falling naturally. When a downward pressure is applied to the first frame 410 or the second frame 420 (e.g., by an operator pressing it with their hand), the frictional force is overcome, causing the first frame 410 or the second frame 420 to rotate. This allows the first locking piece 640 to be moved away from the space below the first locking platform 321 by the rack 620, thus unlocking the first locking platform 321. This structure not only locks the pressing mechanism 300 in its idle (folded) state, preventing damage to the device from external pressure when it is not in use, but also provides a reliable mechanical limit for the folded state of the burning rack 400. This ensures that the rack remains stably folded during storage and transportation, preventing accidental unfolding that could cause collisions or damage, further enhancing the safety and practicality of the device.

[0037] Or / and, such as Figure 5 , Figure 6 , Figure 7As shown, in another structure, for example, a resilient locking element 650 is also provided on the rack 620. This resilient locking element 650 includes a locking spring 651 and a locking gear 652. When the burner rack 400 is flipped to a folded state, the rack 620, carrying the resilient locking element 650, moves to a position below a specific location on the burner rack 400. This causes the locking gear 652, under the elastic force of the locking spring 651, to abut and lock against a specific part of the burner rack 400 (such as the rack edge, the first gear set 411, or the second gear set 421). For example, under the elastic force of the locking spring 651, the locking gear 652 abuts against and locks within the tooth gap of the second gear set 421. This allows the gear tooth gap to engage with the locking gear 652, achieving a more stable locking mechanism. The spring force of the locking spring 651 is designed to overcome the weight of the burning machine rack 400 itself, thus firmly locking the burning machine rack 400 in the folded position and preventing it from automatically falling and unfolding due to gravity. When a downward pressure is applied to the first rack body 410 or the second rack body 420 (e.g., by the operator pressing it with their hand), the spring force of the locking spring 651 is overcome, causing the first rack body 410 or the second rack body 420 to rotate. This allows the first locking member 640 to be driven by the rack 620 and deviate from the space below the first locking platform 321, thereby unlocking the first locking platform 321. The above structure provides a reliable mechanical limit for the folded state of the burning machine rack 400 through the elastic locking member 650, ensuring that the rack can remain stably folded during storage and transportation, preventing accidental unfolding that could cause collisions or damage, further improving the safety and practicality of the equipment.

[0038] like Figure 1 , Figure 2 As shown, in some embodiments, at least two rows of programmers 500 are provided on both the first rack body 410 and the second rack body 420, and these two rows of programmers 500 are staggered in the vertical direction. Specifically, in the unfolded state, the first rack body 410 has two rows of programmers 500 arranged vertically, with two programmers 500 in each row arranged horizontally. Similarly, the second rack body 420 has two rows of programmers 500 arranged vertically, with two programmers 500 in each row arranged horizontally. By adopting a multi-row vertical layout on the first rack body 410 and the second rack body 420, the number of programming positions 111 is significantly increased without increasing the horizontal width of the equipment, thereby improving the single programming capacity and optimizing the space utilization and production efficiency of the equipment.

[0039] In some embodiments, both the first frame 410 and the second frame 420 are telescopically oriented in the left-right direction (not shown in the figures). Specifically, both the first frame 410 and the second frame 420 are telescopic structures. For example, one end of the first frame 410 and the second frame 420 opposite to each other (the end closer to the left-right center line) is rotatably mounted on the vertical frame 200, while the opposite ends (the outer ends of the first frame 410 and the second frame 420 in the left-right direction) are also telescopically oriented. By making the outer ends of the first frame 410 (the end opposite to the left-right center line in the left-right direction) and the second frame 420 telescopic structures, when more programmers 500 need to be installed, additional programmers 500 can be installed by extending the telescopic structures at the outer ends. This increases the adaptability and flexibility of the device, enabling it to be compatible with more main control boards and improving the device's versatility. In addition, when the operator manually changes the burner rack 400 from a folded state to an unfolded state, the telescopic structure pulled out on the first rack body 410 or the second rack body 420 can protrude and be used as a handle, which provides a force-bearing point for applying force to the burner rack 400, making it more convenient for the operator to use.

[0040] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
