Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to an electric energy meter terminal welding platform. Background Art

[0002] The production process of electric energy meters involves welding between terminals and circuit boards. In order to ensure the welding effect, the circuit board needs to be placed stably. In traditional manual welding, the circuit board is generally placed directly on a platform (such as a desktop) with a surface larger than the circuit board for operation. The entire circuit board can be attached to the platform, and the circuit board is not easy to move during operation. However, after welding is completed, it is also inconvenient to replace the circuit board, which has certain shortcomings.

[0003] Another method is to use a platform with a surface smaller than the circuit board and place the circuit board on the platform. Since there is a gap near the bottom of the peripheral side of the circuit board, the circuit board can be removed through the gap for welding when replacing the circuit board. However, due to the existence of the gap, the arm can also easily touch the circuit board during the welding process, causing the circuit board to shift, which also has certain shortcomings.

[0004] Therefore, the present invention provides an electric energy meter terminal welding platform to solve the above problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an electric energy meter terminal welding platform, and the problem to be solved is: to provide an electric energy meter terminal welding platform that can stably place circuit boards and facilitate the replacement of circuit boards, thereby facilitating stable welding and easy operation.

[0008] In the natural state, the placing plate is affected by the elastic limiter A and is in the same horizontal position as the clamping plate. When the lifting plate is controlled to rise, the two slides move away from each other, thereby driving the two clamping plates away from each other and driving the push rod to rise at the same time. When the push rod pushes the placing plate, the rear side of the placing plate tilts backward and downward.

[0010] When the placement plate is in a horizontal position, the side pressure plate contacts the pressing block. When the rear side of the placement plate tilts downward and rearward, the side pressure plate rotates relative to the threaded column to move away from the pressing block.

[0018] Preferably, a plurality of fixing holes are provided on the base, and a roller B is provided on the top of the top rod.

[0019] The beneficial effects of the present invention are:

[0020] 1. In the present invention, the height of the lifting plate is controlled, 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 first controlled to move away from each other and keep the supporting plate in a horizontal state, and then the circuit board is placed on the supporting plate, and then the two clamping plates are controlled to move closer to each other and clamp the circuit board. The clamped circuit board has high stability and is conducive to welding operations. When replacing the circuit board, the two clamping plates are controlled to move away from each other until the push rod pushes the placement plate to tilt the placement plate, releases the circuit board, and drives the circuit board to tilt and slide down to achieve automatic board lowering, and then the two clamping plates are controlled to gradually reset, first driving the placement plate to reset to a horizontal state, at which time the next circuit board can be placed on the placement plate, and then the two clamping plates continue to reset to clamp the next circuit board, which is easy to operate.

[0021] 2. When the present invention is welding the circuit boards, even if the arms on both sides hit the corresponding clamping plates and generate an inward thrust on the clamping plates, since the two circuit boards are located between the two clamping plates, the circuit boards can still remain stable and will not be displaced, which is conducive to welding operations.

[0022] 3. The present invention can clamp circuit boards of different sizes through two clamping plates, so it can be suitable for the production of electric energy meters of different specifications and is flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will refer to the attached Figures 1 to 9 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] An electric energy meter terminal welding platform, as shown in the attached Figure 1 As shown, it includes a base 1, a column 2 and a placement plate 13 which are arranged in sequence from bottom to top, wherein the base 1 is provided with a plurality of fixing holes, through which the entire device can be fixed on the welding station, and 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-right direction, so that the placement plate 13 can rotate forward and backward along the front-back direction, and an elastic limiter A (not drawn in the figure) is provided between the placement plate 13 and the column 2, and the elastic limiter A is used to limit the placement plate 13 to be in a horizontal state in a natural state, specifically, the elastic limiter 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.

[0035] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a clamping mechanism is provided on the placement plate 13, and the clamping mechanism includes two clamping devices arranged on the left and right sides of the placement plate 13, and the clamping device includes a clamping plate 20, a telescopic member A12, a slide plate 7 and a transmission rod A5. Specifically, the clamping device includes a clamping plate 20, and the clamping plate 20 is in a "T" shape. A telescopic member A12 is provided between the clamping plate 20 and the placement plate 13. In this embodiment, the telescopic member A12 is a rod body that is internally sleeved on the placement plate 13, so that the clamping plate 20 can be close to or away from the placement plate 13. The clamping plate 20 is rotatably connected to the slide plate 7, and the slide plate 7 is in an inverted "T" shape. The upper part of the slide plate 7 is rotatably connected to the lower part of the clamping plate 20, and the rotation axis is coaxial with the rotation axis between the placement plate 13 and the column 2. When the placement plate 13 rotates, the clamping The fixed plate 20 can rotate with the placement plate 13. The column 2 is fixed with a frame 6 by connecting plates arranged on the front and rear sides. The frame 6 includes a cross bar and a longitudinal bar, and the column 2 slides in the vertical direction to a lifting plate 4. In this embodiment, the lifting plate 4 is frame-shaped, and the slide plate 7 is arranged on the cross bar of the frame 6 along the left and right directions, and a transmission rod A5 is arranged between the lifting plate 4. The transmission rod A5 is rotatably connected with the slide plate 7 and the lifting plate 4 respectively, and the rotation axis is along the front and rear directions. A push rod 17 is provided near the front side of the lifting plate 4. In this embodiment, a roller B16 is provided on the top of the push rod 17, and an elastic limiter B3 for elastically limiting the lifting plate 4 is also included. In this embodiment, the elastic limiter B3 is arranged between the lifting plate 4 and the base 1, and a pull rod 8 is provided on the left side of the left clamping plate 20.

[0036] Working principle: In the natural state, the placement plate 13 is in the same horizontal position as the clamping plate 20 under the action of the elastic limiter A. The lifting plate 4, under the action of the elastic limiter B3, makes the two clamping plates 20 relatively close to each other. When the lifting plate 4 is controlled to overcome the elastic limiter B3 and rise, the lifting plate 4 drives the two slide plates 7 away from each other through the two transmission rods A5, and then drives the two clamping plates 20 away from each other, and at the same time drives the push rod 17 to rise. When the push rod 17 pushes the placement plate 13 through the roller B16, the placement plate 13 tilts backward and downward.

[0037] During specific operation, in a natural state, the distance between the two clamping plates 20 is smaller than the width of the circuit board to be welded. First, pull the pull rod 8 with one hand to drive the left slide plate 7 to slide to the left, thereby driving the lifting plate 4 to rise, and then the two slide plates 7 move away from each other, driving the two clamping plates 20 move away from each other, so that the distance between the two clamping plates 20 is larger than the circuit board to be welded, and when the placement plate 13 is still in a horizontal state, use the other hand to place the circuit board to be welded on the placement plate 13, and then slowly release the pull rod 8. Under the action of the elastic limiter B3, the lifting plate 4 descends, driving the two slide plates 7 closer to each other, and then driving the two clamping plates 20 closer to each other, until the two clamping plates 20 clamp the circuit board. After clamping, the circuit board terminals can be welded. After welding, pull the pull rod 8 again until the two clamping plates 20 move away from each other, release the circuit board, and the lifting plate 4 rises to the push rod 17. The push rod 17 pushes the rear side of the placement plate 13 to tilt backward and downward through the roller B16, so that the circuit board with the terminals welded can slide backward along the placement plate 13, and then slowly release the pull rod 8. Under the action of the elastic limiter A and the elastic limiter B3, the placement plate 13 first restores to a horizontal state. At this time, the next circuit board to be welded can be placed on the placement plate 13 with the other hand. Finally, the two clamping plates 20 clamp the next circuit, and then the next circuit board terminal can be welded. The circuit can be replaced by analogy.

[0038] In the present invention, the circuit board is clamped by two clamping plates 20, which has high stability. Even if the arm accidentally touches the slide plate 7 or the clamping plate 20 during welding, and an inward thrust is generated on the slide plate 7 or the clamping plate 20, since the circuit board is located between the two clamping plates 20, the clamping plate 20 will not be forced to move inward, that is, the circuit board can be ensured to always remain stable during welding, which is conducive to welding. When replacing the circuit board, the present invention only needs one hand to push and pull the pull rod 8, and the other hand can place the next circuit board on the placement plate 13, which is easy to operate. In the present invention, circuit boards of different sizes can be clamped by two clamping plates 20, so that it can be suitable for the production of electric energy meters of different specifications and is flexible to use.

[0039] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in this embodiment, an auxiliary frame 14 is provided on the clamping plate 20 located on the left side to slide along the front-to-back direction. The auxiliary frame 14 is in a "C" shape, and the right end extends to the right. An auxiliary support device 15 is provided on the auxiliary frame 14 to slide along the left-right direction. The auxiliary support device 15 is used to support the welding gun. A telescopic member B11 is provided along the left-right direction on the left side of the clamping plate 20, and a side pressure plate 10 is connected through the telescopic member B11. The rotating shaft between the clamping plate 20 and the slide plate 7 is fixedly penetrated through the slide plate 7. One end of the rotating shaft is rotatably connected to the clamping plate 20, and the other end is fixedly connected to a threaded column 9. The threaded column 9 is threadedly connected to the side pressure plate 10, and a pressure block 22 adapted to the side pressure plate 10 is provided on the auxiliary frame 14.

[0040] Working principle: When the placement plate 13 is in a horizontal position, the clamping plate 20 and the side pressure plate 10 are both in a horizontal state. At this time, the side pressure plate 10 contacts the pressure block 22 to prevent relative sliding. When the placement plate 13 tilts downward and backward, the side pressure plate 10 rotates relative to the threaded column 9, thereby moving away from the pressure block 22.

[0041] During specific use, when the placement plate 13 is in a horizontal state and a circuit board is placed thereon, the auxiliary frame 14 is located above the circuit board. When a welding gun is used through the auxiliary frame 14, the welding gun can be placed on the auxiliary support device 15. By adjusting the positions of the auxiliary frame 14 and the auxiliary support device 15, the welding gun is made to correspond to the terminal welding point for welding. Since the side pressure plate 10 and the pressure block 22 are in contact with each other at this time, the auxiliary frame 14 can be positioned to a certain extent. When the welding gun is used through the auxiliary support device 15, the hand and the welding gun can be relatively stable, which is conducive to stable welding.

[0042] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in this embodiment, an elastic limiter C21 is provided between the auxiliary frame 14 and the pressing block 22, and the elastic limiter C21 is along the left-right direction. The auxiliary frame 14 is provided with a slide groove 19 along the front-back direction. A vertical plate 18 is slidably provided in the slide groove 19, and a control handle 24 is provided on the top of the vertical plate 18. A transmission rod B23 is provided between the vertical plate 18 and the pressing block 22, and the transmission rod B23 is rotatably connected to the pressing block 22 and the vertical plate 18 respectively, and the rotation axis is along the vertical direction. In the natural state, the pressing block 22 is affected by the elastic limiter C21, away from the auxiliary frame 14, and is at the maximum distance from the vertical plate 18. When the vertical plate 18 moves relative to the slide groove 19, the pressing block 22 is close to the vertical plate 18.

[0043] Working principle: when the vertical plate 18 is driven to slide in the slide groove 19, the pressure block 22 is close to the vertical plate 18. When the placement plate 13 is in a horizontal state, the auxiliary frame 14 is driven to move by the control handle 24, which can drive the vertical plate 18 to slide in the slide groove 19, so that the pressure block 22 is close to the vertical plate 18, reducing the pressure between the pressure block 22 and the side pressure plate 10, which is convenient for operation. After releasing the control handle 24, the vertical plate 18 and the control handle 24 are reset through the elastic limiter C21, and the pressure between the pressure block 22 and the side pressure plate 10 is restored, and the positioning is automatically restored.

[0044] As attached Figure 4 , Figure 5 As shown, the auxiliary frame 14 may also be provided with an auxiliary handle 25 adapted to the control handle 24, and both the control handle 24 and the auxiliary handle 25 are columnar. When moving the auxiliary frame 14, the control handle 24 and the auxiliary handle 25 can be held by one hand to bring the control handle 24 and the auxiliary handle 25 close to each other, thereby ensuring that before the auxiliary frame 14 moves, the vertical plate 18 first slides a certain distance in the slide groove 19 to make the pressure block 22 completely away from the side pressure plate 10.

[0045] As attached Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, in this embodiment, the auxiliary support device 15 includes a support block 151, and a movable block 152 is movably connected to the support block 151. A gun barrel 153 is provided on the movable block 152. An elastic limiter D154 is slidably provided on the support block 151. When the bottom end of the gun barrel 153 is close to the placement plate 13, the elastic limiter D154 is driven to approach the frame 6.

[0046] Working principle: the support block 151 is automatically positioned in the front and rear directions with the auxiliary frame 14. When using a welding gun, the welding gun is placed in the gun barrel 153. The welding gun can move in the left and right directions with the gun barrel 153. When the movable block 152 rotates, the gun barrel 153 and the welding gun are driven to rotate. When welding the circuit board, the elastic limiter D154 approaches the frame 6, increasing the pressure between the frame 6, thereby positioning the support block 151. During welding, it plays a role in positioning the welding gun, and assists in precise welding.

[0047] As attached Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, in this embodiment, the support block 151 is in a "U" shape, the front and rear sides of the movable block 152 are rotatably connected with the front and rear sides of the support block 151, and the rotation axis is along the front and rear direction. The top of the support block 151 and the corresponding part of the frame 6 are penetrated by an elastic limiter D154 in the vertical direction. The top of the elastic limiter D154 is provided with an upper pressure plate 155, and the bottom is provided with a roller A (not shown in the figure). The upper pressure plate 155 can be connected to the support block 151 in a sliding manner in the vertical direction. In the natural state, the upper pressure plate 155 and the dynamic elastic limiter D154 are lowered by gravity, so that the roller A contacts the frame 6. When the support block 151 moves, the roller A rolls adaptively to reduce the friction with the frame 6, thereby providing a certain degree of protection for the frame 6. When the bottom end of the gun barrel 153 is close to the placement plate 13, the movable block 152 drives the upper pressure plate 155 and the elastic limiter D154 to move downward, thereby increasing the pressure between the roller A at the bottom of the elastic limiter D154 and the frame 6, thereby providing a positioning effect.

[0048] As attached Fig. 9 As shown, in this embodiment, the elastic limiter B3, the elastic limiter C21 and the elastic limiter D154 have the same structure, and all include an inner sleeve and an outer sleeve, and a spring is provided between the inner sleeve and the outer sleeve.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0050] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
