Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a conductive layer welding device for preparing a composite busbar. Background Art

[0002] A composite busbar refers to a multi-layer composite connecting bar, whose main function is to distribute electricity. Its advantages include safety and reliability, compact structure, low impedance, low inductance, etc.

[0003] The structure of the composite busbar mainly includes a conductive layer, an insulating layer, and a terminal. The conductive layer is generally made of various copper sheets, and the insulating layer is generally made of an epoxy resin film or a polyester film. An insulating layer is provided between adjacent conductive layers. The main function of the above-mentioned welding equipment is to weld and fix the terminal on the conductive layer.

[0004] On the other hand, the conductive layer can be rectangular, irregular, or even non-planar and bent. The shape of the terminal block is also uncertain. On the same conductive layer, there may be terminal blocks of various styles, such as lateral protrusions, upward warping, and downward bending. This puts forward higher practical requirements for the above welding equipment.

[0005] For example, the Chinese utility model patent with authorization announcement number CN219005027U and authorization announcement date 2023.05.12 discloses an automatic welding device for the conductive layer of a composite busbar, whose structure includes a placement plate, a bracket one, a left support plate, a bracket two, a support block, a slide rod, a right support plate, a fixed plate, an automatic welding head, an electric push rod, an equipment box, a slide plate, a square rod, a fixed block one, a slide groove one, a first slider, a soft pad, a threaded rod, a fixed block two, and a second slider.

[0006] The general structural principle and advantages of the automatic welding device in this utility model patent are as follows: when the electric push rod is operated to rise, one end of the right support plate remains in a fixed position, and the other end rises to the right support plate in an inclined state, so that the busbar can be placed on the upper surface of the fixed plate fixed to the right support plate, and the threaded rod is operated to fix the busbar by the first slider, and then the automatic welding head performs welding. Through the cooperation of the above structure, when welding the angled busbar, the electric push rod can be operated to adjust the angle to fix the angle, thereby improving the work efficiency and the flexibility of changing the angle of the angle welding.

[0007] However, in actual use, the automatic welding device still has at least the following two shortcomings, which are also the technical problems to be solved by the present invention, namely: First, the positions of the two clamping structures are fixed, and they can only clamp the two sides of the bent conductive layer parallel to the bent edge. When the above-mentioned side positions need to be welded with terminal blocks, the clamping structure itself will interfere with the welding operation, or the distance between the above-mentioned two sides is relatively small and cannot be clamped at the same time, which is very troublesome; Second, its two clamping structures can only press the bent conductive layer separately and completely to fit it on its two fixed plates. At this time, if you want to weld a laterally protruding and upwardly tilted terminal, the automatic welding device is suitable, but if you want to weld a downwardly bent terminal, the above clamping method is not applicable.

[0008] So in summary, there is an urgent need for a new type of welding equipment with a more flexible, changeable and practical clamping method, which can be used to weld various types of terminal blocks that protrude laterally, warp upward, and bend downward on the conductive layer, and then prepare various types of more practical bent composite busbar products. Summary of the invention

[0009] The present invention provides a conductive layer welding device for preparing a composite busbar, which can be arranged on a bottom plate in the manner of columns, a lifting cylinder, a hinge, an orifice plate unit, a movable pressing block unit, an opening, and a U-shaped frame unit, so that: 1. The downward pressing and fixing effect of the movable pressing block unit on the conductive layer has the characteristic of adjustable position, which can adapt to the size of the conductive layer and avoid the wiring terminals; 2. The movable pressing block unit that has been removed from the orifice plate unit can fully and appropriately lift the conductive layer at the opening and the U-shaped frame unit to ensure that the wiring terminals bent downward can be smoothly welded.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problem is: a conductive layer welding device for preparing a composite busbar, the structure of which includes a base plate, a column, a lifting cylinder, and a hinge, and also includes two orifice plate units arranged on the hinge and respectively connected to the column and the lifting cylinder, a plurality of movable pressure block units arranged on the orifice plate unit and used to press down and fix the conductive layer, an opening arranged on the orifice plate unit, and a U-shaped frame unit arranged on the lower surface of the orifice plate unit and used to lift the conductive layer at the opening by installing the movable pressure block unit that has been removed.

[0011] A further preferred technical solution is that the orifice plate unit includes a rectangular plate connected to the hinge and used to fix the column or press down the lifting cylinder, and screw holes arranged on the rectangular plate and evenly spaced in a linear arrangement and used to install the movable pressure block unit.

[0012] A further preferred technical solution is that the movable pressing block unit includes a screw rod arranged on the screw hole, a pressing block, an oblong hole arranged on the pressing block and used to pass through the screw rod, and a fastening nut arranged on the screw rod and used to press down the pressing block.

[0013] A further preferred technical solution is that the movable pressing block unit also includes a holding ring arranged on the screw rod.

[0014] A further preferred technical solution is that the U-shaped frame unit includes a vertical plate arranged on the lower surface of the rectangular plate, a horizontal plate arranged on the vertical plate, and a supporting screw hole arranged on the horizontal plate and used for installing the screw rod.

[0015] A further preferred technical solution is that the shape of the opening and the cross-sectional shape of the pressing block are both rectangular, and the length and width of the opening are 2-4 mm larger than the length and width of the cross-sectional shape of the pressing block.

[0016] A further preferred technical solution is that: a height fine-adjusting frame unit for lifting the rectangular plate is also provided on the cylinder shaft of the lifting cylinder by installing the removed movable pressure block unit.

[0017] A further preferred technical solution is that the height fine-tuning frame unit includes a mounting plate, a mounting screw hole arranged on the mounting plate and used to connect the cylinder shaft, a vertical rod arranged at one end of the mounting plate and used to insert the removed pressure block, and a circular hole arranged at the other end of the mounting plate and used to support the pressure block by installing the removed screw rod.

[0018] A further preferred technical solution is that the circular hole is a screw hole or a light hole.

[0019] A further preferred technical solution is that the retraction distance of the holding ring on the end surface of the screw is ≥ 2 cm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0032] As attached Figure 1-10 As shown, a conductive layer welding device for preparing a composite busbar comprises a bottom plate 11, a column 12, a lifting cylinder 13, and a hinge 14, and also comprises two orifice plate units 1 arranged on the hinge 14 and respectively connected to the column 12 and the lifting cylinder 13, a plurality of movable pressing block units 2 arranged on the orifice plate unit 1 and used for pressing down and fixing the conductive layer a, an opening 3 arranged on the orifice plate unit 1, and a U-shaped frame unit 4 arranged on the lower surface of the orifice plate unit 1 and used for lifting the conductive layer a at the opening 3 by installing the movable pressing block unit 2 that has been removed.

[0033] In this embodiment, the column 12, the lifting cylinder 13, and the welding arm base 15 are screwed and installed on the bottom plate 11. There are two orifice plate units 1, one of which is fixed to the column 12, and the other is only pressed on the lifting cylinder 13, and finally the two orifice plate units 1 are hinged by 2-3 hinges 14, such as existing common hinges.

[0034] At this point, the conductive layer welding device can stably support the conductive layer a that has been bent once. Generally, the angle of the bend is in the range of 100-150°. For details, please refer to the attached Figure 2 .

[0035] The number of the movable pressing block units 2 is 3-10. When the welding device is in use, 1-4 movable pressing block units 2 are pressed on the single side plate of the conductive layer a. When the conductive layer a needs to be welded with the terminal block b bent downward, one of the movable pressing block units 2 needs to be removed from the orifice plate unit 1 first, and then installed on the opening 3 and the U-shaped frame unit 4, and finally adjusted to protrude upward at the opening 3 to ensure that one of the single side plates of the conductive layer a leaves enough space below for the terminal block b bent downward. For details, please refer to the attached Figure 3 .

[0036] On the other hand, the number of the opening 3 and the U-shaped frame unit 4 is one, and both are arranged on the horizontal, fixed and immovable perforated plate unit 1. Therefore, when both sides of the conductive layer a need to be installed with the downwardly bent connecting terminals b, the welding device is not applicable.

[0037] However, in general, for a composite busbar, in order to make its wiring method more reasonable and to separate the subsequent wiring as much as possible, multiple wiring terminals b are generally separated left and right and staggered up and down. Therefore, the above-mentioned inapplicable situation generally rarely occurs.

[0038] The orifice plate unit 1 includes a rectangular plate 101 connected to the hinge 14 and used to fix the column 12 or press down the lifting cylinder 13, and screw holes 102 arranged on the rectangular plate 101 and evenly spaced in a linear arrangement and used to install the movable pressure block unit 2.

[0039] In this embodiment, the material of the orifice plate unit 1 is stainless steel or plastic, and the opening 3 is formed to avoid the screw hole 102 to avoid the incomplete screw hole 102 .

[0040] The hinge 14 is screwed to the side of the rectangular plate 101 , also avoiding the screw holes 102 , so that the movable pressing block unit 2 can be installed on all the screw holes 102 as needed.

[0041] The movable pressing block unit 2 includes a screw rod 201 disposed on the screw hole 102, a pressing block 202, an oblong hole 203 disposed on the pressing block 202 and used to pass through the screw rod 201, and a fastening nut 204 disposed on the screw rod 201 and used to press down the pressing block 202.

[0042] In this embodiment, the movable pressing block unit 2 is made of plastic, and the length and width of the pressing block 202 are slightly smaller than the length and width of the opening 3, so that when the removed pressing block 202 lifts the single-side plate of the conductive layer a at the opening 3 as needed, the former is not easily displaced laterally in the latter to a large extent.

[0043] The main function of the movable pressing block unit 2 is to fully and appropriately press down the conductive layer a, and the secondary function is to lift up the conductive layer a as needed. The former needs to be triggered after selecting one of the many screw holes 102, and the general method of use is as follows: First, the lifting cylinder 13 rotates the rotatable rectangular plate 101 to a suitable angle, that is, the two rectangular plates 101 are respectively attached to the two single-side plates of the conductive layer a; Second, a completely exposed screw hole 102 is selected near the side of the conductive layer a, and the screw rod 201 is first screwed thereon, and the standard for screwing in place is that the lower end of the screw rod 201 is exposed and visible; Third, rotating and sliding the pressing block 202 on the screw 201, so that the pressing position and pressing area of ​​the pressing block 202 on the conductive layer a are sufficient and appropriate, and then placing the pressing block 202 on the conductive layer a; Fourth, the fastening nut 204 is rotated downward to make the pressing block 202 itself immobile, and the conductive layer a is fully and appropriately pressed. During this period, the pressing block 202 can be held and fixed by hand.

[0044] At this point, the entire installation method is completed. After all the wiring terminals b are welded, the disassembly method of the movable pressure block unit 2 is generally the same as the above-mentioned installation method. Moreover, during disassembly, even if the pressure block 202 rotates and loosens along with the fastening nut 204, it is not a big problem and it is difficult to scratch the conductive layer a.

[0045] On the other hand, the word "active" in the active pressing unit 2 mainly includes the following two meanings: First, there are many screw holes 102, and the movable pressing block unit 2 can select a suitable one to install. Even if the conductive layer a is a special-shaped style, the movable pressing block unit 2 can fully press and fix it. This pressing method is flexible, adjustable, practical and efficient; Second, the oblong hole 203 is provided on the pressing block 202, so the former can both slide and rotate on the screw 201, which makes the selection operation of the above-mentioned screw hole 102 very flexible and not unique. Even if a relatively inappropriate screw hole far away from the side of the conductive layer a is selected, the pressing block 202 can fully and appropriately press the side of the conductive layer a, which is also flexible and efficient.

[0046] The width of the oblong hole 203 is slightly larger than the diameter of the screw 201 , the length of the pressing block 202 is 3-5 cm, and the length of the oblong hole 203 is 70-80% of the length thereof.

[0047] The movable pressing block unit 2 further includes a holding ring 205 disposed on the screw rod 201 .

[0048] In this embodiment, the holding ring 205 is sleeved or clamped on the screw 201, or is cast on the latter. Its first function is to make the rotation of the screw 201 relatively comfortable when it is rotated to be threaded into the screw hole 102. Otherwise, the operator's fingers need to hold the threaded part with great force, which is very inefficient and uncomfortable.

[0049] The U-shaped frame unit 4 includes a vertical plate 401 disposed on the lower surface of the rectangular plate 101 , a horizontal plate 402 disposed on the vertical plate 401 , and a supporting screw hole 403 disposed on the horizontal plate 402 and used for mounting the screw rod 201 .

[0050] In this embodiment, the vertical plate 401 also needs to avoid the screw rod 201 when selecting the installation position.

[0051] In addition, the supporting screw hole 403 is arranged in the middle position of the horizontal plate 402, and is also aligned with the middle position of the opening 3, so that the fastening nut 204 can support the middle of the pressure block 202 as much as possible, avoiding the harmful phenomenon of the pressure block 202 tilting itself when supporting the pressure block 202.

[0052] The general method of using the movable pressing block unit 2 on the U-shaped frame unit 4 is as follows: First, the idle movable pressing block unit 2 is generally screwed to the screw hole 102 near the side, and is first removed from the screw hole 102, and the screw rod 201 and the fastening nut 204 are separated; Second, the screw rod 201 passes through the supporting screw hole 403 from bottom to top, and the fastening nut 204 is reconnected to the screw rod 201, and then the pressing block 202 is placed on the opening 3, and the lower end of the former naturally falls on the fastening nut 204; Third, the screw rod 201 is rotated on the supporting screw hole 403, and / or the fastening nut 204 is rotated on the screw rod 201, so that the pressing block 202 is raised or lowered as required until it fully and appropriately lifts the conductive layer a, so that the conductive layer a on this side has been tilted, and sufficient space has been reserved for the downwardly protruding connecting terminal b; Fourth, when the number of movable pressing block units 2 on the rectangular plate 101 is sufficient, the movable pressing block unit 2 may not even be removed from the U-shaped frame unit 4, and it is only necessary to lower the pressing block 202 until the upper surface thereof does not protrude. When the number of movable pressing block units 2 is relatively small, the movable pressing block unit 2 can be reused on the rectangular plate 101 by first unscrewing the fastening nut 204 and then unscrewing the screw 201.

[0053] It should be noted that when the conductive layer a is lifted up on the fixed, horizontal rectangular plate 101, it is not necessary and impossible to install other movable pressure block units 2 thereon. The clamping and fixing effect of the conductive layer a is entirely provided by the movable pressure block units 2 on the rotatable rectangular plate 101, and a plurality of movable pressure block units 2 can be appropriately provided thereat.

[0054] At this time, the clamping and fixing strength of the conductive layer a is still sufficient and can fully meet the stability requirements of the welding and installation operation of the terminal block b.

[0055] The shape of the opening 3 and the cross-sectional shape of the pressing block 202 are both rectangular, and the length and width of the opening 3 are 2-4 mm larger than the length and width of the cross-sectional shape of the pressing block 202 .

[0056] In this embodiment, the thickness of the rectangular plate 101 is 0.2-1.0 cm, and the thickness of the pressing block 202 is 1.5-2.0 cm.

[0057] The cylinder shaft of the lifting cylinder 13 is also provided with a height fine-adjusting frame unit 5 for lifting the rectangular plate 101 by installing the removed movable pressing block unit 2.

[0058] In this embodiment, the use of the movable pressing block unit 2 mainly includes the following three modes, and for a single movable pressing block unit 2, only one can be triggered: First, screw the screw hole 102 to press down and fix the conductive layer a; Second, the opening 3 protrudes upward to support and fix one side of the relatively inclined conductive layer a, so that the wiring terminal b protruding downward has sufficient alignment space during welding; Third, it is installed on the height fine-tuning frame unit 5 to stably support the lower surface of the rotatable rectangular plate 101.

[0059] In addition, it should be noted that: First, the rotation and lifting action of the rectangular plate 101 mainly depends on the jacking cylinder 13, and the lifting and lowering adjustment effect of the movable pressing block unit 2 on the height fine-tuning frame unit 5 is only fine-tuning, supplementary, and auxiliary; Secondly, when the lifting cylinder 13 controls the lifting and lowering of the rectangular plate 101, the movable pressing block unit 2 may slide and rub on the lower surface of the rectangular plate 101. Therefore, the lower surface of the rotatable rectangular plate 101 can be provided with an existing common smooth coating as needed, or a more direct solution is that before each lifting and lowering adjustment of the lifting cylinder 13, the rectangular plate 101 is manually lifted up, and then lowered after the cylinder stops moving, and this is repeated many times until the angle between the rectangular plate 101 and the fixed rectangular plate 101 is adapted to the angle amplitude of the conductive layer a.

[0060] The height fine-adjustment frame unit 5 includes a mounting plate 501, a mounting screw hole 502 arranged on the mounting plate 501 and used to connect the cylinder shaft, a vertical rod 503 arranged at one end of the mounting plate 501 and used to insert the removed pressure block 202, and a circular hole 504 arranged at the other end of the mounting plate 501 and used to support the pressure block 202 by installing the removed screw rod 201.

[0061] In this embodiment, the second function of the grip ring 205 is to be reflected on the height fine-tuning frame unit 5. At this time, the screw rod 201 and the vertical rod 503 are inserted into the oblong hole 203 together, so that the pressing block 202 is fixed horizontally, and the screw rod 201 has a height-adjustable function on the round hole 504, which enables the above-mentioned "height fine-tuning" effect to be achieved.

[0062] The effect of the adjustable support height is achieved by the end surface of the grip ring 205. Figure 8 and 10 .

[0063] On the other hand, the vertical rod 503 is a round rod, and the size between it and the circular hole 504 is set so that it and the screw rod 201 can simultaneously clamp the two arc-shaped ends of the oblong hole 203, so that the pressing block 202 has a sufficiently stable lateral limiting effect on the height fine-tuning frame unit 5.

[0064] At this time, although the pressing block 202 is supported on only one side, the supporting strength is still sufficient. Alternatively, the vertical rod 503 is set as a screw rod, on which a supporting nut is provided, which is used to support the pressing block 202 more stably together with the fastening nut 204.

[0065] The circular hole 504 is a screw hole or a light hole.

[0066] In this embodiment, when the circular hole 504 is a screw hole, the Figure 8 At this time, the fastening nut 204 can be installed at any one of the screw rod 201 and the cylinder shaft, and both of the above positions have the effect of reinforcing the screw connection structure.

[0067] When the circular hole 504 is a bare hole, i.e., there is no thread on it, then the Fig.10 At this time, the fastening nut 204 can only be screwed to the screw rod 201 and supported on the upper surface of the mounting plate 501. In this way, the threaded section of the cylinder shaft is also screwed to the mounting screw hole 502. Although the screw connection stability is poorer than the above method, it can also effectively support the rectangular plate 101.

[0068] In other words, the flexible use of the movable pressing block unit 2 on the height fine-tuning frame unit 5 removes the restrictions on the style requirements of the circular hole 504, which is very practical.

[0069] The holding ring 205 is retracted by a distance L≥2 cm on the end surface of the screw rod 201 .

[0070] In this embodiment, the above-mentioned end face refers to the end face which is relatively closer to the holding ring 205 among the two end faces, and the above-mentioned retraction distance L makes it possible for: when the screw rod 201 is placed on the height fine-tuning frame unit 5, the former has a sufficient size to laterally engage the limiting pressure block 202.

[0071] On the other hand, when the height fine-tuning frame unit 5 is matched with a movable pressing block unit 2, the original "point-shaped" support style of the lifting cylinder 13 on the rectangular plate 101 is upgraded to "linear", and the support stability is better. The above-mentioned "linear" position refers to one of the upper length edges of the pressing block 202.

[0072] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
