Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and more specifically, to an automatically corrected parallel welding machine. Background Technology

[0002] To protect electronic components and prevent circuit failure caused by moisture, atmospheric ions, or corrosive atmospheres, encapsulation is often necessary to reduce the impact of the operating environment. Current encapsulation methods typically involve welding a cover plate to a base using a parallel seam welder to create a sealed space. During welding, the cover plate and base are placed in two locating grooves, and then a robotic arm moves the cover plate to fit snugly against the base. Finally, parallel seams are welded around the perimeter of the cover plate and base. However, to ensure smooth insertion into the locating grooves, gaps must be maintained between the grooves and the cover / base. Therefore, positional misalignment can easily occur when the cover plate is moved onto the base, affecting the airtightness of the sealed space and shortening the lifespan of the electronic components. Utility Model Content

[0003] This utility model discloses an automatically calibrated parallel welding machine, which aims to improve the problem of positional misalignment that easily occurs when the existing parallel welding machine is used to encapsulate cover plates.

[0004] The present invention adopts the following solution:

[0005] An automatically calibrated parallel welding machine includes a turntable, a transverse guide rail, and an identification mechanism, an adsorption mechanism, a first roller electrode mechanism, and a second roller electrode mechanism disposed on the transverse guide rail. The turntable is driven to rotate via a rotating component and can move in a direction perpendicular to the transverse guide rail. A positioning fixture is mounted on the turntable, which has a first limiting groove for limiting a cover plate and a second limiting groove for limiting a base. The identification mechanism identifies the positions of the cover plate and the base. The adsorption mechanism is configured to adjust the weld seam of the cover plate to align with the weld seam of the base when adsorbing the cover plate, based on the positions identified by the identification mechanism. The first and second roller electrode mechanisms are used for parallel welding of the weld seam.

[0006] As a further improvement, the adsorption mechanism includes a suction cup, a rotating component, and a lifting component. The rotating component is coaxially arranged with the suction cup and is used to drive the suction cup to rotate. The lifting component is used to drive the suction cup to move in the vertical direction.

[0007] As a further improvement, the adsorption mechanism also includes pre-welded components symmetrically arranged on both sides of the suction cup, which are used to pre-weld the cover plate to pre-fix it to the base.

[0008] As a further improvement, the pre-welded component includes a fixed base, a clamping block, and a pre-welded electrode. The rotating component and the fixed base are connected and fixed to the lifting component via a connecting plate, and the pre-welded electrode is disposed on the fixed base via the clamping block.

[0009] As a further improvement, the identification mechanism, the adsorption mechanism, and the first roller electrode mechanism are all driven by a first driving member to move synchronously along the transverse guide rail, and the second roller electrode mechanism is configured to be driven by a second driving member to move along the transverse guide rail.

[0010] As a further improvement, the first roller electrode mechanism and the second roller electrode mechanism are located on both sides of the turntable, and roller electrodes are arranged on the side facing the turntable.

[0011] As a further improvement, a first slider and a second slider are arranged on the transverse guide rail. The first roller electrode mechanism and the adsorption mechanism are fixed to the first slider, and the identification mechanism is fixed to the adsorption mechanism and can rise and fall synchronously with the adsorption mechanism. The second slider is connected to the second roller electrode mechanism.

[0012] As a further improvement, the identification mechanism, adsorption mechanism, first roller electrode mechanism and second roller electrode mechanism are arranged sequentially from left to right on the transverse guide rail.

[0013] As a further improvement, the positioning fixture is provided with at least two first limiting grooves, and the second limiting groove is arranged side by side with the first limiting groove.

[0014] As a further improvement, the positioning fixture is provided with a boss, and the first limiting groove is formed on the boss so that the first limiting groove and the second limiting groove are at different heights.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. This application incorporates an identification mechanism to align the weld seam of the cover plate with the weld seam of the base during the adsorption process, thereby ensuring the airtightness of the welded seal. During welding, the operator places the cover plate and base into the first and second limiting grooves, respectively. The identification mechanism then identifies the positions of the cover plate and base, followed by the adsorption mechanism lifting the cover plate and adjusting its angle based on the identified position information before placing it back onto the base. The identification mechanism includes a camera; the image captured by the camera is transmitted to a computer, which calculates the positional deviation between the cover plate and the base, and then drives the adsorption mechanism to adjust the position of the cover plate.

[0017] 2. The adsorption mechanism includes pre-welded parts symmetrically arranged on both sides of the suction cup. While the suction cup adsorbs the cover plate, the two sides of the cover plate are pre-welded, so that the cover plate can be pre-fixed to the base when it is placed on the base, avoiding the problem of cover plate position displacement when the suction cup separates from the cover plate, and further ensuring the accuracy of the welding position.

[0018] 3. The identification mechanism, adsorption mechanism, and first roller electrode mechanism are all driven to move by the first driving member, while the second roller electrode mechanism is driven to move by the second driving member. This design requires only two driving members to enable the four mechanisms to move along the transverse guide rail, resulting in a simple structure and reducing the manufacturing cost of the welding equipment.

[0019] 4. The positioning fixture has at least two first limiting grooves, and a second limiting groove is arranged side by side with the first limiting grooves to simplify the movement path of the cover plate on the base. At the same time, the setting of multiple limiting grooves helps to improve welding efficiency.

[0020] 5. The positioning fixture is provided with a boss, and the first limiting groove is formed on the boss, so that the first limiting groove and the second limiting groove are at different heights. This helps the operator to distinguish between the two limiting grooves and avoid misplacement. Attached Figure Description

[0041] Example

[0042] Combination Figures 1 to 10This embodiment provides an automatically calibrated parallel welding machine, including a turntable 1, a transverse guide rail 2, and an identification mechanism 3, an adsorption mechanism 4, a first roller electrode mechanism 5, and a second roller electrode mechanism 6 disposed on the transverse guide rail 2. The turntable 1 is movable along the direction perpendicular to the transverse guide rail 2 and is equipped with a positioning fixture 11. The positioning fixture 11 has a first limiting groove 111 for limiting the cover plate 8 and a second limiting groove 112 for limiting the base 9. The identification mechanism 3 is used to identify the positions of the cover plate 8 and the base 9. The adsorption mechanism 4 is configured to adjust the weld of the cover plate 8 to be aligned with the weld of the base 9 when adsorbing the cover plate 8, based on the position identified by the identification mechanism 3. The first roller electrode mechanism 5 and the second roller electrode mechanism 6 are used for parallel welding of the weld.

[0043] It should be noted that in this embodiment, by setting the identification mechanism 3, the adsorption mechanism 4 can align the weld seam of the cover plate 8 with the weld seam of the base 9 when adsorbing the cover plate 8, thereby ensuring the airtightness of the welding and sealing. For example, the turntable 1 is mounted on the longitudinal guide rail 7, and the transverse guide rail 2 is located above the longitudinal guide rail 7. The structure driving the turntable 1 to rotate can be a motor and gear structure, and the structure driving the turntable 1 to move along the longitudinal guide rail 7 can be a motor and lead screw structure, but is not limited to these. The identification mechanism 3, the adsorption mechanism 4, the first roller electrode mechanism 5, and the second roller electrode mechanism 6 can all move along the transverse guide rail 2. During welding, the operator places the cover plate 8 and the base 9 in the first limiting groove 111 and the second limiting groove 112 respectively, then drives the identification mechanism 3 to identify the positions of the cover plate 8 and the base 9, then drives the adsorption mechanism 4 to pick up the cover plate 8 and adjust the angle of the cover plate 8 according to the identified position information, and then places the cover plate 8 on the base 9. The identification mechanism 3 includes a camera 31. Images captured by the camera 31 are transmitted to a computer, which calculates the positional deviation between the cover plate 8 and the base 9. The computer then drives the adsorption mechanism 4 to adjust the position of the cover plate 8. The circuitry between the computer and the camera 31 is existing technology and will not be described further here. The camera 31 can be an industrial camera with visual inspection capabilities to achieve higher position detection accuracy.

[0044] In a preferred embodiment, the adsorption mechanism 4 includes a suction cup 41, a rotating component 42, and a lifting component 43. The rotating component 42 is coaxially arranged with the suction cup 41 and is used to drive the suction cup 41 to rotate. The lifting component 43 is used to drive the suction cup 41 to move vertically. Both the rotating component 42 and the lifting component 43 are electrically connected to a control unit, which may be a PLC. The rotating component 42 may be a servo motor, which is connected to the suction cup 41 via a coupling. The lifting component 43 may be a cylinder, but is not limited to these specific types. The rotating component 42 allows the suction cup 41 to adjust the angle of the cover plate 8 when adsorbing it. It should be noted that the cover plate 8 and the base 9 are restricted by the limiting groove, and their positional offset is very small. Therefore, the suction cup 41 can finely adjust the angle of the cover plate 8. The suction cup 41 adsorbs the cover plate 8 at the center of the first limiting groove 111. After adsorbing the cover plate 8, the cover plate 8 is rotated to the desired position and then moved to be aligned with the base 9. The cover plate 8 is then placed on the base 9.

[0045] Furthermore, the adsorption mechanism 4 also includes pre-welded components 44 symmetrically arranged on both sides of the suction cup 41. The pre-welded components 44 are used to pre-weld the cover plate 8 to pre-fix it to the base 9. Exemplarily, the pre-welded component 44 includes a fixed base 441, a clamping block 442, and a pre-welded electrode 443. The rotating component 42 and the fixed base 441 are connected and fixed to the lifting component 43 via a connecting plate 45. The pre-welded electrode 443 is positioned on the fixed base 441 via the clamping block 442. The pre-welded electrode 443 pre-welds both sides of the cover plate 8 while the suction cup 41 adsorbs the cover plate 8, thus pre-fixing the cover plate 8 to the base 9 when it is placed on the base 9. This avoids the problem of the cover plate 8 shifting position when the suction cup 41 separates from the cover plate 8, further ensuring the accuracy of the welding position. The welding principle of the pre-welded component 44 is the same as the working principle of the two roller electrode welding, both being existing technologies, and will not be described further here.

[0046] Based on the above embodiments, in an optional embodiment of this utility model, the identification mechanism 3, the adsorption mechanism 4, and the first roller electrode mechanism 5 are all driven by the first driving member to move synchronously along the transverse guide rail 2, and the second roller electrode mechanism 6 is configured to move along the transverse guide rail 2 by the second driving member. In this embodiment, only two driving members are needed to realize the movement of four mechanisms along the transverse guide rail 2, which is simple in structure and helps to reduce the manufacturing cost of welding equipment. Specifically, the identification mechanism 3, the adsorption mechanism 4, the first roller electrode mechanism 5, and the second roller electrode mechanism 6 are arranged sequentially from left to right on the transverse guide rail 2. The transverse guide rail 2 is equipped with a first slider 21 and a second slider 22. The first roller electrode mechanism 5 and the adsorption mechanism 4 are fixed to the first slider 21, and the identification mechanism 3 is fixed to the adsorption mechanism 4 and can rise and fall synchronously with the adsorption mechanism 4; the second slider 22 is connected to the second roller electrode mechanism 6. The driving structure for the slider to move along the transverse guide rail 2 can be a motor screw structure, but is not limited to it and is not specifically limited. Preferably, the identification mechanism 3 is positioned higher than the adsorption mechanism 4 to avoid interference with the positioning fixture 11 during the process of rising and falling with the adsorption mechanism 4.

[0047] Preferably, the first roller electrode mechanism 5 and the second roller electrode mechanism 6 are located on opposite sides of the turntable 1, with roller electrodes positioned facing the turntable 1. During welding, the two roller electrodes move towards the base 9 to be positioned on opposite sides of the base 9. (Refer to...) Figures 6 to 10 The weld seam of the cover plate 8 and the base 9 is rectangular. First, two opposite sides are welded, and then the turntable 1 is rotated to weld the other two opposite sides.

[0048] In other embodiments, the positioning fixture 11 has at least two first limiting grooves 111, and a second limiting groove 112 is arranged side-by-side with the first limiting grooves 111 to simplify the movement path of the cover plate 8 onto the base 9. Simultaneously, the arrangement of multiple limiting grooves improves welding efficiency. Preferably, the positioning fixture 11 has a boss 113, and the first limiting grooves 111 are formed on the boss 113, so that the first limiting grooves 111 and the second limiting grooves 112 are at different heights. This helps operators distinguish between the two types of limiting grooves and avoids misplacement.

[0049] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are within the protection scope of this utility model.
