Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a terminal welding platform for electric energy meter. BACKGROUND

[0002] The electric energy meter involves welding work between the terminal and the circuit board during the production process. In order to ensure the welding effect, the circuit board needs to be placed stably. When the traditional manual welding is performed, the circuit board is generally placed on a platform (such as a desktop) whose surface is larger than the circuit board to operate, which can make the circuit board entirely stick to the platform, and the circuit board is not easy to move during operation. However, after the welding is completed, it is also inconvenient to replace the circuit board, which has certain defects.

[0003] Another kind is to use a platform whose surface is smaller than the circuit board, and the circuit board is placed on the platform. Since there is a gap between the circuit board close to the bottom of the side, the circuit board can be taken out through the gap for welding when the circuit board is replaced. However, since there is a gap, the arm is also easy to contact the circuit board during the welding process, which causes the circuit board to deviate, which also has certain defects.

[0004] Therefore, the present application provides a terminal welding platform for electric energy meter to solve the above problems. SUMMARY

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present application provides a terminal welding platform for electric energy meter, which solves the problem of providing a terminal welding platform for electric energy meter which can stably place the circuit board and is convenient to replace the circuit board, thereby facilitating stable welding and convenient operation.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] A terminal welding platform for electric energy meter, comprising a base, a column and a placing plate arranged in sequence from bottom to top, the placing plate is rotationally connected with the column, and the rotation axis is along the left-right direction, an elastic limiting piece A is arranged between the placing plate and the column, a clamping mechanism is arranged on the placing plate, the clamping mechanism comprises clamping devices arranged on the left and right sides of the placing plate, the clamping device comprises a clamping plate, an elastic piece A is arranged between the clamping plate and the placing plate, the clamping plate is rotationally connected with a sliding plate, a frame is fixedly arranged on the column and slides along the vertical direction to arrange a lifting plate, the sliding plate is arranged on the frame along the left-right direction and an elastic limiting piece B is arranged between the lifting plate and the sliding plate, the elastic limiting piece B elastically limits the lifting plate.

[0008] In its natural state, the placement plate is in the same horizontal position as the clamping plate under the action of the spring limiter A. When the lifting plate is raised, the two sliding plates move away from each other, which in turn causes the two clamping plates to move away from each other, and at the same time causes the top rod to rise. When the top rod pushes the placement plate, the rear side of the placement plate tilts backward and downward.

[0009] Preferably, an auxiliary frame is slidably provided on one of the clamping plates in the front-back direction, and an auxiliary support device is slidably provided on the auxiliary frame in the left-right direction. A telescopic member B in the left-right direction is provided on the outside of the clamping plate, and a side pressure plate is connected through the telescopic member B. A rotating shaft between the clamping plate and the sliding plate is fixedly passed through the sliding plate. One end of the rotating shaft is rotatably connected to the clamping plate, and the other end is fixedly connected to a threaded column. The threaded column is threadedly connected to the side pressure plate. A pressure block adapted to the side pressure plate is provided on the auxiliary frame.

[0010] When the placement plate is in a horizontal position, the side pressure plate contacts the pressure block. When the rear side of the placement plate tilts downwards and backwards, the side pressure plate rotates relative to the threaded column, thereby moving away from the pressure block.

[0011] Preferably, an elastic limiting member C is provided between the auxiliary frame and the pressure block, the elastic limiting member C21 being along the left-right direction, and the auxiliary frame being provided with an elastic limiting member C21 along the left-right direction.

[0013] Preferably, in its natural state, the pressure block is moved away from the auxiliary frame by the elastic limiting member C and is at the maximum distance from the upright plate. When the upright plate moves relative to the slide groove, the pressure block moves closer to the upright plate.

[0014] Preferably, the auxiliary frame is provided with an auxiliary handle adapted to the control handle.

[0015] Preferably, the auxiliary support device includes a support block, a movable block is movably connected to the support block, a gun barrel is provided on the movable block, and an elastic limiting member D is slidably provided on the support block. When the bottom end of the gun barrel approaches the placement plate, it drives the elastic limiting member D to approach the frame.

[0016] Preferably, the support block is U-shaped, the front and rear sides of the movable block are rotatably connected to the front and rear sides of the inner support block, and the rotation axis is along the front and rear direction. An elastic limiting member D is inserted vertically at the top of the support block corresponding to the frame. An upper pressure plate is provided on the top of the elastic limiting member D. When the bottom end of the gun barrel is close to the placement plate, the movable block drives the upper pressure plate and the elastic limiting member D to move downward.

[0017] Preferably, the bottom of the elastic limiting member D is provided with a roller A.

[0018] Preferably, the elastic limiting member B is arranged between the lifting plate and the base, and one side of the clamping plate is provided with a pull rod.

[0019] Preferably, the base is provided with a plurality of fixing holes, and the top rod is provided with a plurality of rollers B.

[0020] The present application has the following beneficial effects:

[0021] In the present application, the height of the lifting plate, the distance between the two clamping plates and the angle of the supporting plate are controlled. Before placing the circuit board, the two clamping plates are controlled to move away from each other, and the supporting plate is kept in a horizontal state. Then the circuit board is placed on the supporting plate. Subsequently, the two clamping plates are controlled to move close to each other, and the circuit board is clamped. The clamped circuit board has high stability, which is beneficial for welding operation. When replacing the circuit board, the two clamping plates are controlled to move away from each other until the top rod drives the placing plate to tilt, which releases the circuit board and makes it slide and fall. Automatic unloading is realized. Then the two clamping plates are gradually reset, and the placing plate is reset to a horizontal state. At this time, the next circuit board can be placed on the placing plate. Subsequently, the two clamping plates are reset to clamp the next circuit board. The operation is convenient.

[0022] When welding the circuit board, even if the two arms touch the corresponding clamping plates and generate an inward pushing force on the clamping plates, the circuit board can still remain stable and will not displace, which is beneficial for welding operation.

[0023] 3、In the present application, the two clamping plates can clamp circuit boards of different sizes, so it can be applied to the production of electric energy meters of different specifications, and is flexible to use. BRIEF DESCRIPTION OF DRAWINGS

[0034] The following will refer to the attached reference. Figures 1 to 9 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] A welding platform for electricity meter terminals, as shown in the attached figure. Figure 1 As shown, the device includes a base 1, a column 2, and a placement plate 13 arranged sequentially from bottom to top. The base 1 has several fixing holes, through which the entire device can be fixed to the welding station. The placement plate 13 is used to place the circuit board to be welded. The placement plate 13 is rotatably connected to the column 2, and the rotation axis is along the left and right direction, allowing the placement plate 13 to rotate back and forth in the front and back direction. An elastic limiting member A (not shown in the figure) is provided between the placement plate 13 and the column 2. The elastic limiting member A is used to limit the placement plate 13 to be in a horizontal state in its natural state. Specifically, the elastic limiting member A can be a torsion spring, and when the front side of the placement plate 13 rotates forward and downward to the maximum angle, the placement plate 13 is in a horizontal state.

[0036] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the placing plate 13 is provided with a clamping mechanism, which includes two clamping devices arranged on the left and right sides of the placing plate 13. The clamping device includes a clamping plate 20, an extension member A12, a sliding plate 7 and a transmission rod A5. Specifically, the clamping device includes the clamping plate 20, which is in the shape of a "T". The clamping plate 20 is provided with the extension member A12 between the clamping plate 20 and the placing plate 13. In this embodiment, the extension member A12 is a rod body sleeved in the placing plate 13, so that the clamping plate 20 can be close to or away from the placing plate 13. The clamping plate 20 is rotatably connected with the sliding plate 7, which is in the shape of an inverted "T". The upper part of the sliding plate 7 is rotatably connected with the lower part of the clamping plate 20, and the rotation shafts are coaxial with each other. When the placing plate 13 rotates, the clamping plate 20 can rotate with the placing plate 13. The stand 2 is fixed with a frame 6 through the front and rear connecting plates. The frame 6 includes a horizontal rod and a vertical rod. The stand 2 is slid along the vertical direction to be provided with a lifting plate 4. In this embodiment, the lifting plate 4 is in the shape of a frame. The sliding plate 7 is arranged on the horizontal rod of the frame 6 along the left and right directions, and is provided with the transmission rod A5 between the lifting plate 4. The transmission rod A5 is rotatably connected with the sliding plate 7 and the lifting plate 4, and the rotation shafts are along the front and rear directions. The lifting plate 4 is provided with a top rod 17 close to the front side. In this embodiment, the top rod 17 is provided with a roller B16. The lifting plate 4 is further provided with an elastic limiting member B3 for elastically limiting the lifting plate 4. In this embodiment, the elastic limiting member B3 is arranged between the lifting plate 4 and the base 1. The left side of the clamping plate 20 is provided with a pull rod 8.

[0037] Working principle: in the natural state, the placing plate 13 is in the horizontal position with the clamping plate 20 under the action of the elastic limiting member A. The lifting plate 4 is close to each other under the action of the elastic limiting member B3, so that the two clamping plates 20 are close to each other. When the lifting plate 4 is lifted by overcoming the elastic limiting member B3, the lifting plate 4 drives the two sliding plates 7 to be away from each other through the two transmission rods A5, so as to drive the two clamping plates 20 to be away from each other, and drive the top rod 17 to be lifted. When the top rod 17 pushes the placing plate 13 through the roller B16, the placing plate 13 is inclined downwardly to the rear.

[0038] Specific work, natural state, the distance between the two clamping plate 20 is less than the width of the circuit board to be welded, first one hand pull rod 8, drive the left slide plate 7 to the left slide, in turn drive the lifting plate 4 is raised, in turn two slide plate 7 away from each other, drive two clamping plate 20 away from each other, the distance between the two clamping plate 20 is greater than the circuit board to be welded, and the placement plate 13 is also in the horizontal state, with the other hand will be welded to the circuit board on the placement plate 13, then slowly release the pull rod 8, under the action of elastic limiting piece B3, lifting plate 4 is lowered, drive two slide plate 7 close to each other, in turn drive two clamping plate 20 close to each other, until the two clamping plate 20 will be clamped circuit board, then the circuit board terminal can be welded, after welding, pull rod 8 again, until two clamping plate 20 away from each other, release the circuit board, lifting plate 4 rises to the top rod 17 through the roller B16 drive the back side of the placement plate 13 to the back down tilt, so that the terminal welding of the circuit board can slide along the placement plate 13 to the back, then slowly release the pull rod 8, under the action of elastic limiting piece A and elastic limiting piece B3, the placement plate 13 first restore horizontal state, at this time can be placed in another hand will be welded to the next circuit board on the placement plate 13, finally two clamping plate 20 will be clamped next circuit, the next circuit board terminal can be welded, in turn, and the circuit can be replaced.

[0039] The two clamping plates 20 are used for clamping the circuit board in the application, which has high stability, and even if the arm accidentally touches the slide plate 7 or the clamping plate 20 when welding, the slide plate 7 or the clamping plate 20 generates an inward thrust, since the circuit board is located between the two clamping plates 20, the clamping plate 20 will not move inward under force, that is, the circuit board can always remain stable during welding, which is beneficial to welding; the circuit board needs to be replaced only by pulling the pull rod 8 with one hand and placing the next circuit board on the placement plate 13 with the other hand, which is convenient to operate; the two clamping plates 20 can clamp circuit boards of different sizes in the application, so that it can be applied to the production of different specifications of electric energy meters, and is flexible to use.

[0042] In specific use, when the placing plate 13 is in the horizontal state and the circuit board is placed, the auxiliary frame 14 is above the circuit board, the welding gun can be placed on the auxiliary support device 15 when the auxiliary frame 14 is used, the position of the auxiliary frame 14 and the auxiliary support device 15 is adjusted, so that the welding gun corresponds to the terminal welding point, welding is performed, because the side pressing plate 10 and the pressing block 22 are in contact at this time, the auxiliary frame 14 can be positioned to a certain extent, and the hand and the welding gun can be relatively stable when the welding gun is used through the auxiliary support device 15, which is beneficial to stable welding.

[0044] Working principle: when the vertical plate 18 slides in the sliding groove 19, the pressing block 22 approaches the vertical plate 18; when the placing plate 13 is in a horizontal state, the auxiliary frame 14 is moved by the control handle 24, which drives the vertical plate 18 to slide in the sliding groove 19, so that the pressing block 22 approaches the vertical plate 18, reducing the pressure between the pressing block 22 and the side pressing plate 10, facilitating operation; after the control handle 24 is released, the vertical plate 18 and the control handle 24 are reset by the elastic limiting piece C21, and the pressure between the pressing block 22 and the side pressing plate 10 is restored, automatically restoring the positioning.
