Description

Technical Field

[0001] This utility model relates to the field of electricity meter welding and processing technology, and in particular to a welding fixture for electricity meter indicator lights. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy, also known as a kilowatt-hour meter, energy meter, or kilowatt-hour meter. It refers to instruments that measure various electrical quantities. The hardware of an electricity meter mainly consists of a casing, circuit board, display screen, and LED indicator lights. In the manufacturing process of an electricity meter, the LED indicator lights need to be soldered onto the circuit board. To improve soldering efficiency and convenience, soldering fixtures are used. During soldering, the indicator light head is first placed downwards into the positioning hole on the fixture. Then, the positioning pins on the fixture align with the holes on the circuit board to position and install the circuit board onto the fixture. Next, the indicator light leads are passed through the soldering holes on the circuit board, and finally, the soldering work can be performed.

[0003] However, during the process of placing the LED indicator light into the positioning hole of the welding fixture, the LED indicator light is prone to deflection along its own axis. Moreover, the leads of the LED indicator light are relatively thin, and they are prone to skew when subjected to external forces during transportation or handling. Therefore, it is difficult to ensure that the leads on the LED indicator light correspond to the welding holes on the circuit board. At this time, the welding personnel still need to pass the leads through the welding holes one by one, which makes the welding work still relatively time-consuming and laborious, which will undoubtedly affect the efficiency of the entire welding work. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to ensure the accurate positioning between the LED indicator wires and the soldering holes when placing the circuit board on the soldering fixture, and to propose a soldering fixture for the indicator lights of an energy meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding fixture for an indicator light of an electricity meter includes a base and several positioning posts. The base has several positioning lamp holes. The upper surface of the base is provided with a bracket, which includes two side plates and an upper support plate and a lower support plate located between the two side plates. Both the upper and lower support plates have several through slots for accommodating LED indicator lights. The upper part of the lower support plate is provided with two clamping rods, and two transmission slots are provided on both sides of the clamping rods. Each of the two side plates has a pressing component slidably inserted into it. The two pressing components are respectively connected to the transmission slots on both sides by a transmission assembly, which is used to drive the two clamping rods to slide and straighten the deflected LED indicator light. The lower surface of the upper support plate is provided with a straightening and centering assembly connected to the pressing component, which is used to straighten the skewed lead wire of the LED indicator light.

[0007] In some embodiments, the two clamping rods are arranged in a front-to-back opposite manner and are stacked vertically. The two transmission grooves on each clamping rod are symmetrically distributed from left to right. The transmission grooves are rectangular and the angle between the length direction of the transmission groove and the length direction of the clamping rod is an obtuse angle.

[0008] In some embodiments, the transmission assembly includes a pin, the upper end of which is fixedly connected to the extruder, and the lower end of which passes through the transmission groove on one side of two clamping rods in sequence. The lower end of the pin is fixedly connected to a lower clamping plate, which abuts against the lower surface of the clamping rod located at the lower part. The lower part of the extruder is fixedly connected to an upper clamping plate, which abuts against the upper surface of the clamping rod located at the upper part.

[0009] In some embodiments, the centering and alignment assembly includes a first sliding frame abutting against the lower surface of the upper support plate and a second sliding frame abutting against the lower surface of the first sliding frame. A plurality of first pressing rods arranged in a specific order are fixedly connected to the first sliding frame, and a plurality of second pressing rods arranged in a specific order are fixedly connected to the second sliding frame. A guide sleeve sleeved around the outside of the first sliding frame and the second sliding frame is fixedly connected to the lower surface of the upper support plate.

[0010] In some embodiments, one end of the first sliding frame is fixedly connected to one of the extrusion members, and one end of the second sliding frame is fixedly connected to another extrusion member.

[0011] In some embodiments, the extrusion member is provided with a locking component inside, which is used to fix the extrusion member to the side plate after straightening the lead wire on the LED indicator.

[0012] In some embodiments, the locking assembly includes a fixed seat fixedly connected to the extruder and a stop block slidably connected to the fixed seat along the height direction. The outer end of the stop block is wedge-shaped. A pressure rod is slidably inserted into the fixed seat. A connecting rod is connected between the pressure rod and the stop block. One end of the pressure rod extends outward from the extruder, and the other end is connected to the extruder with a second return spring.

[0013] In some embodiments, a first return spring is connected between the extruder and the side plate.

[0014] In some embodiments, the positioning post includes a limiting post fixed to the upper surface of the base, and the upper surface of the limiting post is fixed with a positioning pin that matches the positioning hole on the circuit board.

[0015] Compared with the prior art, this utility model provides a welding fixture for the indicator light of an electricity meter, which has the following beneficial effects:

[0016] 1. By coordinating the extrusion component, transmission assembly, and clamping rods, pushing the extrusion component inward allows the two clamping rods to press the two leads, thereby rotating the LED indicator back to the correct position and ensuring that the two leads are exactly in the left-right direction. This achieves the purpose of pressing and straightening the deflected LED indicator and leads, so that the leads can better align with the solder holes on the circuit board.

[0017] 2. Through the cooperation of the extrusion component and the centering and straightening component, during the pressing of the extrusion component, the second extrusion rod and the first extrusion rod will squeeze the lead wires on the left and right sides to a certain extent and straighten the skewed lead wires. Therefore, it can also help the lead wires to correspond with the soldering holes on the circuit board. Therefore, during the placement of the circuit board, the lead wires can be easily passed through the corresponding soldering holes, and there is no need for manual wire threading. This makes the soldering work more time-saving and labor-saving, and improves the efficiency of the entire soldering work to a certain extent.

[0018] 3. Through the cooperation of the extrusion component and the locking component, after the lead wire is aligned and positioned, the locking component can fix the extrusion component, the clamping rod and the alignment and centering component, and maintain the extrusion restriction on the lead wire, which makes it easy to pass the lead wire through the welding hole. After welding is completed, the components can be unlocked and reset by pressing the pressure rod. Thus, the alignment and positioning work is more convenient and reliable, and the convenience of welding work is further improved.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1 , Figure 2 and Figure 5 A welding fixture for an indicator light of an electricity meter includes a base 1 and four positioning posts 7. The base 1 has four positioning lamp holes 101 for placing the lamp beads of the LED indicator light 8. A bracket 2 is fixedly installed on the upper surface of the base 1. The bracket 2 includes two side plates 201 and an upper support plate 202 and a lower support plate 203 located between the two side plates 201. The upper support plate 202 and the lower support plate 203 each have several through slots 204 for accommodating the LED indicator light 8. The upper part of the lower support plate 203 has two clamping rods 3. Two transmission slots 301 are opened on both sides of the clamping rods 3. An extrusion member 5 is slidably inserted into each of the two side plates 201. The two extrusion members 5 are respectively connected to the transmission slots 301 on both sides by a transmission assembly 11, which is used to drive the two clamping rods 3 to slide and straighten the deflected LED indicator light 8. The lower surface of the upper support plate 202 has a straightening and centering assembly 4 connected to the extrusion member 5, which is used to straighten the skewed lead wire 801 on the LED indicator light 8.

[0031] The two clamping rods 3 are arranged in a front-to-back opposite manner, and the two clamping rods 3 are stacked vertically. The two transmission grooves 301 on each clamping rod 3 are symmetrically distributed from left to right. The transmission grooves 301 are rectangular, and the angle between the length direction of the transmission grooves 301 and the length direction of the clamping rod 3 is an obtuse angle.

[0032] Reference Figure 4 and Figure 5 The transmission assembly 11 includes a pin 1101. The upper end of the pin 1101 is fixedly connected to the extrusion member 5, and the lower end passes through the transmission groove 301 on one side of the two clamping rods 3 in sequence. The lower end of the pin 1101 is fixedly connected to a lower clamping plate 1102, which abuts against the lower surface of the clamping rod 3 located at the lower part. The lower part of the extrusion member 5 is fixedly connected to an upper clamping plate 1103, which abuts against the upper surface of the clamping rod 3 located at the upper part.

[0033] Reference Figure 5-7 The centering and alignment component 4 includes a first sliding frame 401 abutting against the lower surface of the upper support plate 202 and a second sliding frame 402 abutting against the lower surface of the first sliding frame 401. Both the first sliding frame 401 and the second sliding frame 402 are rectangular. Four first pressing rods 403 are fixedly connected to the first sliding frame 401. The four first pressing rods 403 are linearly arrayed and equidistantly distributed along the length direction of the first sliding frame 401. Four second pressing rods 404 are fixedly connected to the second sliding frame 402. The four second pressing rods 404 are linearly arrayed and equidistantly distributed along the length direction of the second sliding frame 402. Moreover, the four second pressing rods 404 correspond one-to-one with the four first pressing rods 403 and are located at the lower part of each through slot 204. Furthermore, a guide sleeve 405 is fixedly connected to the lower surface of the upper support plate 202 and sleeved around the first sliding frame 401 and the second sliding frame 402.

[0034] One end of the first sliding frame 401 is fixedly connected to one of the extrusion parts 5, and one end of the second sliding frame 402 is fixedly connected to the other extrusion part 5.

[0035] Reference Figure 3 Each extrusion piece 5 is equipped with a locking component 6, which is used to fix the extrusion piece 5 to the side plate 201 after straightening the lead wire 801 on the LED indicator 8.

[0036] The locking assembly 6 includes a fixed base 601 fixedly connected to the extruder 5 and two stops 603 slidably connected to the fixed base 601 along the height direction. The two stops 603 are symmetrically distributed vertically, and the outer surface of the extruder 5 has through holes 503 adapted to the stops 603. The stops 603 can extend to the outside through the through holes 503, and the outer end of the stops 603 is wedge-shaped. A pressure rod 602 is slidably inserted into the fixed base 601. A connecting rod 604 connects the pressure rod 602 and the stops 603. Specifically, one end of the connecting rod 604 is hinged to the stops 603, and the other end is hinged to the pressure rod 602. One end of the pressure rod 602 extends outward from the extruder 5. The end of the extruder 5 inserted into the bracket 2 is open, and an end cap 501 is threaded onto the opening of the extruder 5. A second return spring 605 is connected between the other end of the pressure rod 602 and the end cap 501.

[0037] A first return spring 502 is connected between the extrusion part 5 and the side plate 201, which can drive the extrusion part 5 to return to its original position through its own rebound force.

[0038] Reference Figure 1 and Figure 2 The positioning post 7 includes a limiting post 701 fixed to the upper surface of the base 1. The upper surface of the limiting post 701 is fixed with a positioning pin 702 that is adapted to the positioning hole 902 on the circuit board 9.

[0039] In this utility model, the initial states of the two clamping rods 3, the transmission assembly 11, and the centering and alignment assembly 4 are as follows: Figure 5 and Figure 6 As shown, at this time, the two clamping rods 3 are located at the front and rear of the through groove 204 respectively, and the four first extrusion rods 403 and the four second extrusion rods 404 corresponding to each other are located at the left and right sides of each through groove 204 respectively, and the extrusion part 5 is also in an outward extension state on the side plate 201. At this time, the through hole 503 is located on the outside of the side plate 201.

[0040] When using this fixture for welding, first place the LED beads on the four LED indicator lights 8 downwards into the four positioning lamp holes 101 as required, and ensure that the two leads 801 on the LED indicator lights 8 are on the left and right sides respectively, so that the two leads 801 are roughly aligned with the welding holes 901 on the circuit board 9. After placement, the leads 801 of the LED indicator lights 8 are exactly located in the through groove 204.

[0041] Then, press the outer end of the extrusion member 5 towards the LED indicator 8 to push the extrusion member 5 to slide inward. During this process, the extrusion member 5 will drive the two clamping rods 3 to slide relative to each other through the pin 1101 and the inclined transmission groove 301, thereby sliding the two clamping rods 3 towards the lead wire 801. During this process, the two lead wires 801 on the LED indicator 8 can be squeezed. If the LED indicator 8 was deflected along its axis before this, the two clamping rods 3 can rotate the LED indicator 8 back to the correct position by squeezing the two lead wires 801, thereby ensuring that the two lead wires 801 are just in the left and right direction. This achieves the purpose of squeezing and straightening the deflected LED indicator 8 and lead wires 801, so that the lead wires 801 can better correspond to the soldering holes 901 on the circuit board 9.

[0042] Furthermore, during the pressing of the extrusion component 5, one of the extrusion components 5 will drive the first sliding frame 401 to slide to the left, and the other extrusion component 5 will drive the second sliding frame 402 to slide to the right. This will cause the second extrusion rods 404 and the first extrusion rods 403 on both sides of each through slot 204 to slide towards the two leads 801. If the previous misalignment between the two leads 801 has resulted in an excessive gap between the outer ends of the two leads 801, the sliding second extrusion rods 404 and the first extrusion rods 403 will then exert a certain amount of pressure on the leads 801 on both sides and straighten the misaligned leads 801. Therefore, it can also help the leads 801 align with the soldering holes 901 on the circuit board 9. Then, the circuit board 9 is placed on the four positioning posts 7, ensuring that the positioning holes 902 on the circuit board 9 are fitted onto the positioning pins 702. Since the two clamping rods 3 and the straightening and centering component 4 have already straightened and positioned the leads 801 (the state after straightening and positioning is as follows), Figure 1 and Figure 8 As shown in the figure, during the placement of the circuit board 9, the lead wire 801 can be easily passed through the corresponding solder hole 901, thus eliminating the need for manual wire threading, making the soldering work more time-saving and labor-saving, and improving the efficiency of the entire soldering work to a certain extent.

[0043] Furthermore, during the pressing of the extrusion component 5, the first return spring 502 is compressed to a certain extent. Under the pressure of the side plate 201 on the outer inclined surface of the stop block 603, the stop block 603 will retract into the extrusion component 5. At this time, the stop block 603 will push the pressure rod 602 towards the end cover 501 through the connecting rod 604, thereby compressing the second return spring 605 to a certain extent. When the stop block 603 slides past the side plate 201, the rebound of the second return spring 605 can push the pressure rod 602, the connecting rod 604 and the stop block 603 to reset, so that the stop block 603 extends out and blocks the inner side of the side plate 201. At this time, the clamping rod 3 and the centering and straightening assembly 4 have just completed the centering of the lead wire 801. Therefore, under the restriction of the stop block 603, each component in the extrusion component 5, clamping rod 3 and centering and straightening assembly 4 can be fixed and the compression restriction on the lead wire 801 can be maintained, which is convenient for the lead wire 801 to pass through the welding hole 901 later.

[0044] After welding is completed, press the pressure rod 602 towards the extrusion part 5 to compress the second return spring 605. At the same time, the connecting rod 604 will pull the stop block 603 back into the extrusion part 5. Then, under the rebound force of the first return spring 502, the extrusion part 5 will be pushed back to its original position. At the same time, the extrusion part 5 will reset the clamping rod 3 and the centering and alignment component 4. Then, the welded circuit board 9 and LED indicator 8 can be removed.
