Background Art

[0002] Manual soldering is a typical traditional welding method. It is also a routine operation that cannot be completely avoided during electronic component welding teaching, basic skills training, student innovation experiment production, small batch product trial production, electrical appliance maintenance, and even some exploratory research and design. Although today's technology is developing rapidly, it has made very slow progress in providing convenience for manual soldering. Nowadays, although there are a wide variety of tools for manual soldering on the market, it is difficult to find durable, low-priced and multifunctional tools that can simultaneously perform the functions of blind spot magnification, non-damage clamping of small circuit boards, pressing of patch parts, lifting of inverted plug-ins, and light and flexible carrying. At present, the clamping of circuit boards and devices is mainly focused on the crocodile clip technology route. Although some flat-push clamping products have appeared recently, their functions are still too simple and single. Summary of the invention

[0024] Advantages and effects:

[0025] The present invention proposes a manual soldering magnifying lighting support and clamping combination table, which mainly includes a desktop liquid-filled folding lighting magnifier and a circuit board clamping bracket, a patch component pressing cantilever and an inverted plug-in lifting support frame; the desktop liquid-filled folding lighting magnifier is connected to the magnifier frame base through a liquid-filled base, a lower cantilever of the magnifier, and an upper cantilever of the magnifier. The magnifier frame base and a plurality of transparent lighting frames connected in series and clamped together support and carry the liquid-filled magnifier lens shell, and the upper and lower cantilevers of the magnifier are connected with the base and the magnifier frame base through the convex and concave chuck spring self-locking shaft, thereby realizing the overall folding, extension, contraction, mirror angle adjustment and posture locking; by using the closing and opening of each switch, the light-emitting diodes embedded in the magnifier frame base and the transparent frame cluster connected in series and clamped in series can be lit or turned off as needed; the liquid in the liquid-filled base is poured and blocked through the liquid injection hole, so that the entire desktop magnifier is not easy to move or tip over during use, and the liquid is discharged, thereby meeting the requirements of light weight and simplicity in carrying and transporting. Similarly, by pouring and draining a transparent liquid into and out of the liquid-filled magnifying lens shell, it is possible to achieve both visual magnification of the observed object and lightness in carrying and transporting.

[0026] The relatively independent physical structure of the desktop liquid-filled folding lighting magnifier, the circuit board clamping bracket, and the inverted plug-in lifting support frame allows them to be used in combination according to actual conditions. Usually, when they are all put into use, the position relationship is: the circuit board clamping bracket should be located in the arc area of ​​the base of the desktop liquid-filled folding lighting magnifier, and the inverted plug-in lifting support frame should be located below the circuit board clamping bracket, and the three are placed together on the work platform or desktop.

[0027] The present invention selects the most common and cheap angle-shaped and groove-shaped metals and plastics on the market for the circuit board clamping base and clamping bracket raw materials. With the help of slight modification and bolts and springs, it can achieve flexible flat-push non-destructive clamping of circuit boards within a fairly large size range; the vertically installed column bolts, as well as the clamping cantilever, cantilever clamping sleeve and cantilever clamping spring thereon, meet the needs of pressing and holding the easily movable patch components. According to the needs of the operation, under the premise of no mutual interference, conflict and hindrance to the convenience of welding, multiple clamping cantilevers can be configured on the same column bolt, and there can be more than one column bolt. After one preparation, multiple devices can be welded, thereby greatly improving work efficiency.

[0028] This invention configures bases, inverted plug-in lifting support frames, support bolts and bottom bolts of different shapes and sizes. With the assistance of upper and lower connecting bolts and support springs, it can achieve the support and bearing of inverted plug-in components of different sizes and heights through proper adjustment, thereby reducing the difficulty of vertical inverted stability of the components.

[0029] The present application has a simple, reliable, reasonable structure, complete functions, and low price of finished products. It can not only meet the common manual rapid soldering of various positive plug-ins, inverted plug-ins, and patch parts with almost no blind spots by means of lighting and magnifying glasses, but also utilizes multiple clamping cantilevers to make it difficult for light and small patch devices to move and shift, thereby improving the welding quality and efficiency. At the same time, it also effectively reduces labor intensity and prevents the occurrence of occupational cervical spondylosis. In addition, the inverted plug-in lifting support frame structure reduces the difficulty of stability and alignment of different inverted components; the characteristics of the desktop magnifying glass base and the lens shell injection create a visual magnification requirement that not only meets the stability, posture change, and angle change observation of normal operation, but also takes into account the pursuit of folding and lightness during transportation and carrying, thereby greatly reducing the technical ability requirements for users and promoting novices to master manual soldering skills as soon as possible.

[0030] The present invention is particularly suitable for employee training, student innovation experiments, production, small batch product trial production, electrical appliance maintenance, and even design concept verification and exploratory research under certain simple conditions in the field of electronic component soldering. The prominent problem of manual soldering is that it loses sight of one thing while focusing on another. How to liberate the operator from the contradictory and conflicting requirements of independently and simultaneously holding the soldering iron, feeding the solder wire, clamping the components, and pressing the circuit board to prevent slippage, etc., has never been found a practical solution. This invention is a bold attempt and effort in this regard. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention will be further described below in conjunction with the accompanying drawings:

[0046] For many industries and people, manual soldering is still an indispensable job. How to significantly improve welding quality and work efficiency depends not only on basic skill training, but also on the assistance and help of practical and dexterous tools. Especially in the current situation of small-sized, fine multi-pin integrated circuit chips, how to maximize the arrangement, reliable welding, avoid rework and waste, and achieve fast, light, low labor intensity, avoid occupational diseases and quickly improve welding operation skills is particularly important. The present invention attempts to solve the above-mentioned problems faced by the industry in an all-round way and gradually develop into a practical and cheap product. Filling the functional defects and enhancing the dexterity and convenience of use are the purpose of the present invention.

[0047] At present, manual soldering lighting and field of view magnification are limited to a few light bulbs or light-emitting diodes and small-sized glass and resin magnifiers. Although some desktop lighting magnifiers have improved in lighting range, brightness, and magnifying lens size, they still cannot transcend the rigid thinking mode of simply combining ring lamps and magnifying lenses. In this way, it is impossible to fundamentally and thoroughly eliminate the disadvantages of too large field of view obstruction, many welding constraints, bulky overall appearance, heavy weight, clumsy adjustment, and easy slippage of set posture.

[0048] A manual soldering magnifying lighting support and clamping combined platform, the combined platform comprises a magnifying lighting component and a circuit board clamping and supporting mechanism; the magnifying lighting component and the circuit board clamping and supporting mechanism are used in conjunction with each other;

[0049] The magnifying lighting component comprises a liquid-filled desktop magnifying glass base (1) and a liquid-filled magnifying glass lens shell (6); the liquid-filled magnifying glass lens shell (6) is arranged on the liquid-filled desktop magnifying glass base (1) via an angle-adjustable mechanism;

[0050] The circuit board clamping support mechanism comprises a circuit board clamping bracket (11), a rear circuit board clamping base (13), a front circuit board clamping base (14), front and rear clamping base connecting screws (15) and a front circuit board base pushing spring (16);

[0051] The circuit board clamping bracket (11) is composed of two L-shaped structures, the front and rear clamping base connecting screws (15) pass through the vertical plates of the two L-shaped structures, the rear circuit board clamping base (13) and the front circuit board clamping base (14) are arranged on the front and rear clamping base connecting screws (15) (the rear circuit board clamping base (13) and the front circuit board clamping base (14) are both 7-shaped structures, and the front and rear clamping base connecting screws (15) pass through the vertical plates of the rear circuit board clamping base (13) and the front circuit board clamping base (14)), and the rear circuit board clamping base (13) is fixed to the front and rear clamping base connecting screws (15). The front circuit board clamping base (14) is axially movable along the front and rear clamping base connecting screws (15), and the front and rear clamping base connecting screws (15) are sleeved with a front circuit board base pushing spring (16) capable of pushing the front circuit board clamping base (14) toward the rear circuit board clamping base (13) (that is, the front circuit board base pushing spring (16) is arranged between the front circuit board clamping base (14) and one of the circuit board clamping brackets (11), as shown in the figure);

[0052] The circuit board clamping support mechanism is a structure which is arranged below the liquid-filled magnifying lens housing (6) when in use.

[0053] The front and rear clamping base connecting screw rods (15) are two or more parallel screw rods, each of which is sleeved with a front circuit board base pushing spring (16), and all the front circuit board base pushing springs (16) have the same structure.

[0054] A notch (11-1) for clamping a circuit board is respectively arranged on the rear circuit board clamping base (13) and the front circuit board clamping base (14), and the openings of the two notches (11-1) are opposite to each other.

[0055] One or more clamping mechanisms are arranged on the rear circuit board clamping base (13), the clamping mechanism comprising a vertical cantilever support bolt (19) and a patch clamping cantilever (17), the vertical cantilever support bolt (19) being arranged vertically on the rear circuit board clamping base (13);

[0056] A cantilever clamping sleeve (18) is sleeved on the vertical cantilever support bolt (19), and the cantilever clamping sleeve (18) can move axially relative to the vertical cantilever support bolt (19) (it cannot rotate about the axis, and can also be moved by an existing anti-rotation mechanism, such as a key and a keyway, or the vertical cantilever support bolt (19) is a square axis). The side wall of the cantilever clamping sleeve (18) is provided with two symmetrical notches (18-1), and the strip sliding hole (17-1) of the patch pressing cantilever (17) is sleeved on the notch (18-1) so that the patch pressing cantilever (17) is clamped and limited by the cantilever clamping sleeve (18), and the contact between the notch (18-1) and the inner wall of the strip sliding hole (17-1) is just enough to allow the patch pressing cantilever (17) to move;

[0057] The patch pressing cantilever (17) is a structure that can be pulled and pushed along the direction orthogonal to the generatrix of the cantilever support bolt (19) only under the restraint of the notch of the cantilever clamping shaft sleeve (18).

[0058] Since the patch clamping cantilever 17 is simultaneously face-to-face passed through the long strip hole by the bosses (18-2) of the upper and lower cantilever clamping sleeves 18 and is tightly clamped together (that is, the patch clamping cantilever 17 is limited and clamped by the bosses (18-2) in the upper and lower directions), a cantilever clamping spring 20 is sleeved on the cantilever support bolt (19) above the cantilever clamping sleeve (18). Under the push of the cantilever clamping spring 20, the patch clamping cantilever 17 can only move up and down with the cantilever clamping sleeve 18, and the patch clamping cantilever 17 is pulled and pushed along the orthogonal direction of the cantilever support bolt 19 under the restraint of the boss of the cantilever clamping sleeve 18, and cannot rotate around the latter's busbar or produce an upward or downward movement.

[0059] like Fig. 9 As shown, the patch clamping cantilever (17) can move along the length direction of the patch clamping cantilever (17), that is, the left and right direction, and can also move up and down along the axis direction of the cantilever support bolt 19 together with the upper and lower cantilever clamping sleeves 18.

[0060] Several nuts are set up as needed to fasten them. On each cantilever support bolt 19, a patch clamping cantilever 17 clamped up and down by a cantilever clamping sleeve 18 is set from bottom to top. The top end is pushed downward by a cantilever clamping spring 20 to tighten each group of patch clamping cantilever.

[0061] The circuit board clamping support mechanism, under the joint action of the patch clamping cantilever (17), the cantilever support bolt (19), the cantilever clamping spring (20) and the cantilever clamping shaft sleeve (18), can not only fix the tiny, light and easy to move patch components, but also can arbitrarily rotate, stretch and shrink the position and elevation of the clamping point within a given limit as required.

[0062] A boss (17-2) protruding downward is provided at the bottom of the end of the patch pressing cantilever (17). The patch pressing cantilever 17 is actually a straight or slightly curved rigid spring sheet with elasticity and a long hole in the middle. A boss is specially provided below the end of the cantilever. The fundamental purpose of configuring the boss is to use it to press and grasp the patch components to prevent possible slippage and twisting.

[0063] The liquid-injection table magnifying glass base (1) is connected to the magnifying glass frame base (4) via the magnifying glass lower cantilever (2) and the magnifying glass upper cantilever (3), and the magnifying glass lower cantilever (2) and the magnifying glass upper cantilever (3) form a movable arm structure;

[0064] The bottom end of the lower cantilever arm (2) of the magnifying glass is movably connected to the liquid injection table magnifying glass base (1) through a rotation angle locking device, the upper end of the lower cantilever arm (2) of the magnifying glass is movably connected to the lower end of the upper cantilever arm (3) of the magnifying glass through the rotation angle locking device, and the upper end of the upper cantilever arm (3) of the magnifying glass is movably connected to the magnifying glass frame base (4) through the rotation angle locking device.

[0065] The rotation angle locking device (7) comprises a convex-concave chuck spring self-locking shaft (7-1), a fixed convex-concave chuck (7-2) and a movable convex-concave chuck (7-3) non-circular shaft,

[0066] The fixed convex-concave chuck (7-2) is arranged in the chuck housing (7-5), and the chuck housing (7-5) is fixed to the outer side wall of the lower cantilever (2) of the magnifying glass. The front end of the convex-concave chuck spring self-locking shaft (7-1) passes through the lower cantilever (2) of the magnifying glass and then extends into the chuck housing (7-5). The movable convex-concave chuck (7-3) is located at the front end of the convex-concave chuck spring self-locking shaft (7-1) (and is located in the chuck housing (7-5)). The convex-concave chuck spring self-locking shaft (7-1) can rotate relative to the lower cantilever (2) of the magnifying glass (that is, it rotates with its own axis as the axis). The rear end of the convex-concave chuck spring self-locking shaft (7-1) passes through the outer wall (A) of the upper cantilever (3) of the magnifying glass and then extends into the side cavity (B) of the upper cantilever (3) of the magnifying glass. The convex-concave chuck spring self-locking shaft (7-1) can only move axially relative to the outer wall (A) (it will not rotate relative to the outer wall (A). There are many ways to achieve this. For example, a key in the same axial direction as the convex-concave chuck spring self-locking shaft (7-1) can be provided on the side wall of the convex-concave chuck spring self-locking shaft (7-1), and the outer wall (A) is provided with a keyway that cooperates with the key. The rear end of the convex-concave chuck spring self-locking shaft (7-1) extending into the side cavity (B) is covered with a self-locking push spring (8), the front end of the self-locking push spring (8) is connected to the side wall of the side cavity (B), and the rear end of the self-locking push spring (8) is connected to the convex-concave chuck spring self-locking shaft (7-1); the fixed convex-concave chuck (7-2) and the movable convex-concave chuck (7-3) are engaged (when the cantilever (3) on the magnifying glass drives the convex-concave chuck spring self-locking shaft (7-1) to rotate, the movable convex-concave chuck (7-3) and the fixed convex-concave chuck (7 -2) relative rotation occurs between them. At this time, due to the helical teeth of the fixed convex-concave chuck (7-2) and the movable convex-concave chuck (7-3), the convex-concave chuck spring self-locking shaft (7-1) is driven to move axially into the side cavity (B), so that the compression self-locking push spring (8) is stretched. When the movable convex-concave chuck (7-3) jumps to the position of the next tooth, the compression self-locking push spring (8) contracts so that the movable convex-concave chuck (7-3) engages at the next helical tooth, completing one rotation, and so on until the cantilever (3) on the magnifying glass rotates to the specified position).

[0067] The rotation angle locking device at the position where the upper cantilever arm (3) of the magnifying glass is connected to the frame base (4) of the magnifying glass is consistent with the above. No matter how it is installed, as long as the convex-concave chuck spring self-locking shaft (7-1) can move axially, the convex-concave chuck spring self-locking shaft (7-1) can rotate relative to the frame base (4) of the magnifying glass, and the convex-concave chuck spring self-locking shaft (7-1) and the upper cantilever arm (3) of the magnifying glass do not rotate relative to each other, so that the angle adjustment and temporary positioning (such as Fig.13 as shown).

[0068] A connecting block (1-1) is provided on the base (1), a chuck housing (7-5) is fixed on the outside of the connecting block (1-1), a side cavity is also provided at the bottom end of the lower cantilever (2) of the magnifying glass, a convex and concave chuck spring self-locking shaft (7-1) passes through the connecting block (1-1) and can rotate relative to the connecting block (1-1), at this time, the connecting block is equivalent to the lower cantilever (2) of the magnifying glass in the connection relationship between the lower cantilever (2) of the magnifying glass and the upper cantilever (3) of the magnifying glass, and other structures are similar and are not repeated here (such as Fig.14 as shown).

[0069] Furthermore, a baffle is provided at the other end (rear end) of the movable convex-concave chuck of the non-circular axis, thereby achieving the goal of overall folding and angle self-locking positioning by utilizing a self-locking pushing spring (8).

[0070] The liquid injection magnifying lens housing (6) is connected to a liquid injection and discharge hole.

[0071] According to the needs and convenience of operation and carrying, liquid can be injected or discharged by using the injection hole (9) on the injection table magnifier base (1) and the injection hole (10) on the injection magnifier lens shell (6). In order to prevent the injected liquid from overflowing, the injection hole should be tightly blocked with a plug after the injection.

[0072] The combined platform also includes an inverted plug-in lifting support frame (26), and a support spring (24) is arranged at the bottom of the plug-in lifting support frame (26).

[0073] The support spring (24) is arranged on the base (21) via the lower connecting bolt (23).

[0074] The lifting support frame (26) for inverted plug-in components of different shapes and sizes can lift and carry inverted plug-in components of different sizes and heights with the help of support bolts, bottom bolts (22), a base (21), lower connecting bolts (23), upper connecting bolts (25) and a supporting spring (24).

[0075] The magnifying glass frame base (4) and a plurality of transparent lighting frames (5) connected end to end in series (the existing light strips can be used, which can be bonded around the magnifying glass frame base (4) or clamped around the magnifying glass frame base (4) by using the light strips) support and carry the liquid-filled magnifying glass lens shell (6); the connection between the magnifying glass base (1), the lower cantilever (2), the upper cantilever (3) and the magnifying glass frame base (4) is supported by a convex-concave chuck spring self-locking shaft; the circuit board clamping bracket (11) realizes the clamping of the circuit board during soldering under the joint action of the support foot bolts (12), the front circuit board clamping base (14), the rear circuit board clamping base (13), the front and rear clamping base connecting screws (15) and the front circuit board base pushing spring (16); the inverted plug lifting support frame (26) completes the lifting and supporting mission of the inverted plug component under the help of the bottom foot bolts (22), the base (21) and the support spring (24). The base (21) is arranged on the work surface via base bolts (22).

[0076] The magnifying glass frame base (4) and the plurality of transparent lighting frames (5) connected end to end in series can achieve the purpose of clamping and carrying the liquid-filled magnifying glass shell (6) and installing lighting fixtures. In addition, due to the use of transparent materials and compact size structure, there is almost no visual blind spot and welding operation hindrance.

[0077] The liquid-filled desktop magnifier base (1), the liquid-filled magnifier lens shell (6), the circuit board clamping support (11) and the inverted plug-in lifting support frame (26) are relatively independent in overall physical structure, so as to achieve combined use as needed. Usually, the circuit board clamping support mechanism should be located within the arc area of ​​the liquid-filled desktop magnifier base (1), and the inverted plug-in lifting support frame (26) should be located below the circuit board clamping support mechanism, and the three are placed together on a work platform or a desktop.

[0078] When in use, the circuit board clamping support (11) is fixed to the workbench by means of foot bolts (12), the front circuit board clamping base (14) is adjusted so that the workpiece to be processed is clamped between the two notches (11-1), the plug-in lifting support frame (26) lifts the workpiece to be processed from the bottom, and the boss (17-2) is pressed on the workpiece to be processed. The liquid magnifying lens housing (6) is aligned with the workpiece to be processed.

[0079] The present invention will be further described below in conjunction with the accompanying drawings:

[0080] like Figure 1~Figure 5 As shown, the present invention is a manual soldering magnifying lighting support clamp combination table, which includes three relatively independent components: a desktop liquid-filled folding lighting magnifier, a soldering clamp support bracket and an inverted plug-in support bracket, and a structural diagram of its individual key components.

[0081] like Figure 1 , 2As shown, the desktop liquid-filling folding lighting magnifier is connected in sequence by a convex-concave chuck spring self-locking shaft, which connects the liquid-filling base 1, the lower cantilever 2 of the magnifier, the upper cantilever 3 of the magnifier and the frame base 4 of the magnifier in an axial hinge manner. The frame base 4 of the magnifier and a plurality of transparent lighting frames 5 connected in series have two responsibilities: clamping and carrying the lens shell 6 of the liquid-filling magnifier and realizing the lighting of the working area by using the chip light-emitting diode embedded in the transparent lighting frame 5. The convex-concave chuck spring self-locking shaft is actually composed of convex-concave chucks fixed to the object, which are opposite to each other, a movable convex-concave chuck non-circular shaft and a self-locking push spring 8. The movable convex-concave chuck non-circular shaft is a convex-concave chuck that engages face to face with the fixed convex-concave chuck. The convex-concave chuck spring self-locking shaft can be a rigidly connected non-cylindrical body (such as a prism, an ellipse, a frustum, a keyed cylinder, etc.). A spring stop baffle D fastened by bolts is provided at the other end of the non-circular shaft chuck (convex-concave chuck spring self-locking shaft), and the convex-concave chuck spring self-locking shaft can move smoothly axially.

[0082] Once the fixed convex-concave chuck is engaged with the movable convex-concave chuck, the smooth and rotating movement tendency of the connected parts is blocked with the help of the spring, thereby achieving the purpose of folding, stretching, contracting and adjusting the mirror angle, while satisfying the maintenance and locking of the set position, posture and angle. According to the needs and convenience of operation and carrying, the predetermined purpose can be achieved by injecting or discharging liquid through the injection hole 9 on the injection table magnifier base 1 and the injection hole 10 on the injection magnifier lens shell 6.

[0083] In order to prevent the injected liquid from overflowing, the injection hole should be blocked with a plug after the injection. The injection magnifying glass shell 6 can be cast or blow-molded at one time, or it can be integrated into one by fitting, snapping, buckling or screwing the upper and lower surfaces with rubber rings. As long as the specific material is transparent, drop-resistant, scratch-resistant, chemically stable and resistant to light decay, it can be properly weighed according to density, process simplicity, production difficulty, broad spectrum of injection affinity and cost. As long as the liquid is injected into the injection desktop magnifier base 1 and the injection magnifying glass shell 6, as long as it meets the basic requirements of no deposition, stable performance, no chemical reaction, no harm to human health and non-corrosion, it can be selected between pure water, distilled water, alcohol or others according to many factors such as easy acquisition, easy storage, easy material collection, low price and its density suitable for the target.

[0084] Since the magnifying glass frame base 4 and the transparent lighting frame 5 (the transparent lighting frame 5 is located on the magnifying glass frame base 4, and the transparent lighting frame 5 can be installed with a chip light emitting diode) are made of transparent organic glass or plastic, and the radial additional size expansion is relatively not very prominent, the edge thickness increase is also negligible, and the outer contour of the chip light emitting diode is also very small, the final product provides a huge observation field of view while having almost no visual blind spots, and will not cause excessive hindrance and constraints to operations such as welding, and further improves the effect of existing similar products that force users to stretch their necks to fatigue after long-term work and the occupational disease of cervical infection that may be caused as a result.

[0085] The unidirectional surface light source characteristic of the SMD LED increases the cone angle of the lighting area, which is conducive to creating a shadowless effect, and on the other hand, it does not cause dizziness to the operator's eyes. The lighting LEDs are dispersed and evenly arranged in groups, and the closing and closing control switches of each group are placed on the frame base 4 of the magnifying glass.

[0086] In essence, the final material selection of the desktop magnifier base 1, the lower cantilever 2 and the upper cantilever 3 is not deliberately set. As long as it is coordinated with other parts of the overall product, adapts to the main trend of the times and satisfies the purchasing psychology of customers, driven by the goals of production, sales and profit, it can be selected from iron sheets, aluminum alloys, nylon, coated organic glass and plastics. As for the shape, size and appearance beautification and decoration, stability, lightness, compactness, solemnity, grandeur, durability and ease of production and production are the primary considerations. It should not be too radical or extreme, and strive to coordinate, balance and achieve overall optimization.

[0087] Figure 3The soldering clamping bracket is shown, and the soldering clamping bracket is composed of a circuit board clamping bracket 11, a foot bolt 12, a front circuit board clamping base 14, a rear circuit board clamping base 13, a front and rear clamping base connecting screw 15 and a front circuit board base pushing spring 16. There is one circuit board clamping bracket 11 in front and one in the back, which plays the role of the entire soldering clamping bracket base. Four foot bolts 12 are symmetrically arranged at the front, back, left and right of the bottom. By adjusting the foot bolts 12, the height of the circuit board clamping base can be raised or lowered, and the plane of the clamped circuit board can be flattened or tilted to make soldering easier. In addition, it can also be used to achieve proper coordination with peripheral devices such as desktop magnifiers, inverted plug-in support brackets, etc., making manual soldering more convenient, light and easy. The front circuit board clamping base 14 and the rear circuit board clamping base 13 realize the horizontal push clamping and carrying of the circuit board under the cooperation of the front and rear clamping base connecting screws 15 and the front circuit board base pushing spring 16. Due to the left-right symmetry, balance and parallel distribution characteristics of the front and rear clamping base connecting screws 15 and the front circuit board base pushing spring 16, it is ensured that the force when clamping and carrying the circuit board is mainly manifested as a backward horizontal push. In order to ensure the normal performance of the horizontal push performance, at least two groups of the front and rear clamping base connecting screws 15 and the front circuit board base pushing spring 16 combination should be set (one front and rear clamping base connecting screw 15 and one front circuit board base pushing spring 16 are considered as one group). Although increasing the number is slightly helpful, it is not particularly obvious, so it is not recommended. In addition, because the front and rear circuit board clamping bases are long parallel structures, even if the shape of the circuit board is not a completely regular rectangle, it can generally be clamped relatively firmly. The curved pawls (notches (11-1)) on the front and rear circuit board clamping bases can firmly hold the circuit board and prevent it from sliding or moving sideways. On the other hand, the clamping and unloading of the circuit board can be easily completed by pushing and pulling. At the same time, no damage will be caused to the circuit board. By adjusting or replacing the front and rear clamping base connecting screws 15 or the front circuit board base pushing spring 16, the clamping tightness of the circuit board can be changed within a fairly large range, and the external dimensions of circuit boards of different specifications can be adapted at will to meet the needs of different customer groups and temporary personalized operations.

[0088] Similar to what has been mentioned above, the circuit board clamping bracket 11, the front circuit board clamping base 14 and the rear circuit board clamping base 13 do not have to excessively pursue solidity, magnificence, beauty and perfection, as long as they meet the overall pursuit goals, ensure that they do not affect normal use, and are consistent with the psychological tolerance of consumers. Here, the present invention is more inclined to use the most common and inexpensive angled and grooved metals or plastics on the market, and achieve the predetermined goals on the basis of slightly modified mechanical processing. However, in order to prevent the front circuit board clamping base 14 and the front half of the circuit board clamping bracket 11 from pitching, shifting, and tilting, the thickness of the connecting screws 15 that penetrate the front and rear clamping bases should be appropriately increased (that is, at the same time as the thickness of the screws 15 that penetrate the front and rear clamping bases). Figure 3 Increase the thickness in the left and right directions as shown), or use the side that does not hinder the assembly of surrounding parts (such as Figure 3 The same goal can be achieved by setting a curing sleeve on the left or right side of the component shown. At the rear end of the soldering clamp bracket, the nut on the front and rear clamp base connecting screw 15 is tightly screwed and locked, so there is no pitch, displacement, or tilt problem between the rear part of the circuit board clamp bracket 11 and the rear circuit board clamp base 13, and no special consideration is needed in the design. Regarding the shape of the front circuit board base pushing spring 16, a choice can be made between a tower spring and a cylindrical spring. The two types of springs each have their own advantages and disadvantages. The former has a large range of motion but a large variation in the end face size, so it is necessary to consider meeting many special requirements. The latter is almost the opposite, so it should be taken into account and comprehensively measured. But there is no need to worry too much. Perhaps by adopting different methods, it is possible to adapt to the personalized needs of different users.

[0089] In terms of physical structure, the soldering clamp bracket is relatively independent from the desktop liquid filling folding lighting magnifier, and it can be selected and replaced according to actual operation needs. Generally speaking, the soldering clamp bracket should be located inside the base arc area below the desktop liquid filling folding lighting magnifier, and the two are placed together on the work platform or desktop.

[0090] Anyone who has had manual soldering experience knows that during the soldering process, they often have to beg for help from others, but more often they are often limited by various factors and cannot get what they want. For manual soldering, the operator has to hold the soldering iron to solder, feed the solder wire, clamp the components or hold the circuit board to prevent it from slipping, etc. So many things need to be done by one hand at the same time, forcing people to think hard to find all kinds of tricks, but more often they can only waste time, quality and materials in exchange for the need for manpower. This confinement is a long-standing problem in this field. How to break through this problem is the primary goal pursued by the patch clamping cantilever 17.

[0091] As Figure 3 , Figure 4As shown, in addition to clamping and carrying circuit boards, the soldering clamp has a more important mission, which is to prevent tiny, light and easy-to-move SMD components from slipping and twisting during the soldering process. Especially for small-sized integrated circuit chips with many fine pins, a slight deviation from the preset position and posture will cause uneven device arrangement, affecting the aesthetics of the product. In severe cases, it is easy to cause annoying cold solder joints, short circuits, and hinder the smooth placement of subsequent components, and even cause the entire work to be scrapped. Even if it does not reach the level of complete scrapping, finding and eliminating cold solder joints and inconspicuous short circuits is often annoying, headache-inducing and time-consuming. How to completely avoid or eliminate them in the bud is the most fundamental way out and goal to pursue. On the rear circuit board clamping base 13 at the rear end of the soldering clamping bracket, a number of vertical cantilever support bolts 19 fastened with nuts are arranged as needed, and on each cantilever support bolt 19, one or more groups of patch clamping cantilevers 17 clamped up and down by cantilever clamping sleeves 18 are mounted from bottom to top, and the top end is pushed down by the cantilever clamping spring 20. The patch clamping cantilever 17 is actually a straight or slightly curved rigid spring sheet with elasticity and a long hole in the middle. A boss is specially arranged below its end. The fundamental purpose of configuring the boss is to use it to press and grasp the patch components to prevent possible slippage and twisting. According to the size, shape and adaptability requirements of the patch components, the height, shape, projection size, etc. of the boss should be reasonably set. Similarly, the materials used to make the bosses should also be weighed. The important basis for choosing between hard metals and soft rubber, cork or silicone depends not only on material properties, durability, processing convenience, cost and purchasing convenience, but also on the degree of scratches and damage that may be caused to the pressed object, as well as the anti-scalding and deformation properties once the soldering iron tip touches it. The principle of pressing and holding the patch components by the patch clamping cantilever 17 is that the patch clamping cantilever 17 is tightly buckled together by the bosses of the upper and lower cantilever clamping sleeves 18, which pass through the long strip holes face to face at the same time. Under the push of the cantilever clamping spring 20, the former can only be pulled and pushed along the orthogonal direction of the cantilever support bolt 19 busbar under the restraint of the boss of the cantilever clamping sleeve 18, and cannot rotate around the latter busbar or produce head-up or head-down.

[0092] The cluster of patch clamping cantilevers 17 should be prepared, welded and withdrawn in batches in accordance with the principle of no mutual interference and conflict, under the guidance of facilitating arrangement and withdrawal and not hindering fixed-point observation and welding in the same posture as much as possible, with the back high, the front low, the uniform distribution and the maximum clamping and holding of components. In this way, not only can as many components as possible be welded in one batch, but also the number and time of taking tools and components are effectively eliminated, which is conducive to improving work efficiency and reducing labor intensity. It is also possible to greatly avoid the probability of taking the wrong components, because taking components in batches is easier to concentrate and carry out in a controlled manner by category, which is convenient to overcome the mental inertia caused by fatigue caused by long-term repetitive work.

[0093] Manual soldering cannot completely exclude the use of direct-insert components. Although the current trend is that the use of surface mount components is becoming more and more frequent, direct-insert components still occupy a huge space to a large extent. Direct-insert components are indeed quite often soldered in the forward direction on the circuit board, but inverted soldering, especially on single-sided circuit boards, is more common. The most prominent problem of inverted soldering of direct-insert components is slipping, falling and tilting. This is due to the uneven heights of other welded parts, obstruction of the circuit board and small space, inconvenience of fingers and tools to grasp and clamp, different sizes of pad pin surplus, various pin angles and various weights of components, which further increases the difficulty of solving this difficult problem.

[0094] like Figure 5As shown, the inverted plug-in lifting bracket is composed of a base 21, a bottom bolt 22, a lower connecting bolt 23, an upper connecting bolt 25, a support spring 24 and an inverted plug-in lifting support frame 26. For multiple purposes such as coordination, beauty and practicality, the bottom bolt 22, the lower connecting bolt 23, the upper connecting bolt 25 and the support spring 24 should be symmetrically arranged in front, back, left and right, and the base 21 and the inverted plug-in lifting support frame 26 are mainly in the shape of a rectangular flat plate. In order to reduce the dead weight, the base 21 and the inverted plug-in lifting support frame 26 should be provided with uniform through holes or blind holes according to a certain pattern and mode. As for the production and selection of materials for the base 21 and the inverted plug-in lifting support frame 26, similar to the circuit board clamping bracket of the soldering 4 clamping bracket and the front and rear circuit board clamping base, the most common and cheap angle-shaped and groove-shaped metal or plastic on the market is used through simple mechanical processing such as injection molding and drilling. In order to fully realize the purpose of the inverted plug-in support bracket being widely applicable to different devices, firstly, the adjustment scale of the base bolt 22 should be appropriately set for various operations; secondly, the shape, busbar diameter, wire radius and hardness of the support spring 24 should be comprehensively considered and balanced; thirdly, the shape and size of the base 21 and the inverted plug-in support bracket 26 must be determined according to the constraints of the shape of the circuit board, the distribution position of batch-welded plug-in devices, the size of the device, and the weight. However, when the specific design principles of the inverted plug-in support bracket are finally formulated, the primary use criteria should be followed, that is, the devices should be small first and then large, short first and then high, heavy first and then light, and in order by category. In terms of circuit board layout, it should be inside first and then outside, dense first and then sparse, and difficult first and then easy, so as to minimize the pressure of balance and enhance practicality and high efficiency, low errors, and low labor intensity.

[0095] Generally speaking, the inverted plug-in support bracket is a functional extension of the soldering clamp bracket. In other words, when using the inverted plug-in support bracket, the soldering clamp bracket must also be used. The latter can be separated from the former to play a limited role, but the former can hardly be separated from the latter to play an independent role. That is, if the latter is not used, the former will almost immediately lose its value and significance. In most cases, the inverted plug-in support bracket is located below the soldering clamp bracket, but it may be extended at special moments. It is not ruled out that in some cases, multiple inverted plug-in support brackets will be consciously arranged outside the projection area of ​​the soldering clamp bracket to assist each other in order to achieve unexpected functional effects. No matter how different the specific uses are, the basic characteristic is that the inverted plug-in support bracket and the soldering clamp bracket must be placed together on the work platform or desktop.

[0096] In summary, the present invention realizes the overall folding, extension, contraction, mirror angle adjustment and setting posture locking of the desktop magnifier; by opening and closing each switch as needed, the light-emitting diodes embedded in the frame base and transparent frame cluster of the magnifier are grouped and lit; by injecting transparent liquid into the magnifier base and the liquid-filled magnifier lens shell and plugging the liquid injection hole, the stable and normal use of the desktop magnifier is realized, and the pursuit of portability and carrying is met by discharging the liquid; the soldering clamping bracket achieves a large size range under the joint action of the circuit board clamping bracket, the support foot bolts, the front and rear circuit board clamping bases, the front and rear clamping base connecting screws and the front circuit board base pushing spring. The circuit board can be pushed horizontally, clamped and loaded without loss. The clamping cantilever and cantilever clamping sleeve arranged in groups on the vertical column bolts at the rear end of the soldering clamping bracket can firmly press and hold the patch device under the push of the cantilever clamping spring, so that it will not slip or twist during welding. The inverted plug-in lifting support frame, foot bolts, bottom foot bolts, upper and lower connecting bolts and support springs work together to not only lift inverted plug-in components of different sizes and heights, making welding easier, but also together with the soldering clamping bracket, further enhance the ability to adapt to various special requirements, thereby greatly improving work efficiency, improving welding quality and reducing labor intensity. The invention has a simple and reasonable structure, smart combination and outstanding practicality. It can not only meet the general requirements of manual soldering for small-batch product trial production, electrical appliance maintenance, etc., but also accelerate employee training, student innovation experiments, and production skills improvement. The low processing technology threshold, low cost and easy-to-select raw material market space have all contributed to the easy development of a new product with broad prospects.

[0097] It is not difficult to see from the foregoing that the practical characteristics of the present invention are very obvious. First of all, the three parts of the desktop liquid-filled folding lighting magnifier, the soldering clamp support bracket and the inverted plug-in lifting bracket that constitute the manual soldering magnifying lighting support clamp combination table are relatively independent. If any one or two are missing, the remaining ones can still play a certain original role under the condition of reduced performance. Secondly, the wide range of adaptability of the soldering clamp support bracket and the inverted plug-in lifting bracket greatly improves the ease of coping with different needs and conditions. Finally, the serialization and multi-specification configuration of the soldering clamp support bracket and the inverted plug-in lifting bracket further enriches the overall structure's ability to cope with complex problems, thereby fundamentally enhancing the market competitiveness of the final product and the degree to which the personalized needs of different groups are met.
