Description

Technical Field

[0001] This invention relates to the field of laser welding fixture technology, and in particular to a clamping fixture for laser welding of small precision electronic parts. Background Technology

[0002] With the rapid development of the electronic information industry, electronic components are continuously upgrading towards miniaturization, precision, and integration. Laser welding, with its core advantages such as a small heat-affected zone, high welding precision, good weld formation, and non-contact processing, has become the mainstream process for welding small electronic parts. In laser welding operations, the fixture is the core tooling for ensuring welding accuracy, controlling production cycle time, and stabilizing product yield. Its clamping efficiency, ease of operation, and positioning accuracy directly determine the overall benefits of welding production.

[0003] Currently, the fixtures used for laser welding of electronic components in the industry generally adopt a vertically opening and closing structure, using symmetrical clamping structures at both ends to lock and fix the upper and lower dies. In actual production operations, the upper die must first be raised vertically to a sufficient height to allow operating space for part loading and unloading. Then, the electronic component to be welded is placed into the positioning position of the lower die, and subsequently, the upper die is lowered. The locking of the upper and lower dies is completed by simultaneously operating the clamps at both ends with both hands. The above-mentioned existing fixture structure has the following unavoidable technical defects in practical applications: The operation process is cumbersome and the clamping efficiency is low: the existing fixture adopts a locking structure with left and right double-sided clamps. Both unlocking and locking require the operation of both hands at the same time. It is impossible to open and close the fixture with one hand and pick up and put down the parts with the other hand at the same time. It cannot make full use of the collaborative operation of both hands. The clamping process at a single station is multiple and time-consuming, which seriously restricts the cycle efficiency of mass production.

[0004] Excessive opening and closing stroke and long auxiliary time: The existing fixture is a vertical lifting opening and closing structure. In order to reserve sufficient space for part picking and placing operations, the upper mold needs to move a large vertical distance upward. The auxiliary time for opening and closing action is long, which further prolongs the production cycle of a single product and cannot meet the needs of high-speed mass production.

[0005] Inconvenient fixture changeover and poor adaptability to flexible production: Existing fixtures are mostly fixed to the laser welding machine worktable by screw locking or vacuum adsorption. Screw locking requires repeated disassembly and assembly with the help of tools, which is time-consuming and cumbersome. Vacuum adsorption requires auxiliary equipment such as air source, solenoid valve, and control switch, which has high equipment investment costs and requires manual control of air circuit opening and closing. The operation steps are numerous, making it impossible to achieve rapid changeover production of multi-specification parts and difficult to adapt to flexible production scenarios with multiple varieties and small batches.

[0006] Parts are easily damaged, and product yield is difficult to guarantee: The existing clamping structure is mostly a rigid pressing design, which cannot be adapted to the machining tolerance and thickness deviation of the parts. During the mold closing process, it is very easy to cause precision electronic parts to be crushed, deformed or even damaged due to overpressure, resulting in product defects and increasing production costs. At the same time, rigid pressing is prone to problems of weak pressing, which leads to the displacement of parts during the welding process and affects the welding accuracy. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a fixture for laser welding of electronic parts, comprising a fixture body and a fixture fixing seat assembly for fixing the fixture body, wherein the fixture body includes an upper mold assembly and a lower mold assembly, the upper mold assembly and the lower mold assembly are hinged by a rotating assembly, so that the upper mold assembly can rotate and open relative to the lower mold assembly about a rotation axis; One end of the upper mold assembly is a hinged end connected to the rotating assembly, and the other end is a free end. A hook plate is fixedly provided on the free end. The lower mold assembly is provided with a hook that is adapted to and engages with the hook plate at the position corresponding to the hook plate. The hook plate and the hook cooperate to form a one-sided locking structure, which is used to lock the relative position of the upper mold assembly and the lower mold assembly when the clamp is closed. The rotating assembly includes a cylindrical pin and a torsion spring. The cylindrical pin forms the rotation axis, and the torsion spring is sleeved on the cylindrical pin. The two ends of the torsion spring abut against the upper mold assembly and the lower mold assembly, respectively, to provide the upper mold assembly with an elastic restoring force in the opening direction. The upper mold assembly also includes an upper template, a pressure claw, a pressure claw fixing plate, and a compression spring. The pressure claw is mounted on the lower surface of the upper template through the pressure claw fixing plate. The compression spring is disposed between the pressure claw and the upper template and is used to provide the pressure claw with an elastic clamping force toward the electronic component to be soldered. A carbon steel plate is fixedly installed at the bottom of the lower mold assembly. The clamp fixing seat assembly includes a base, on which a magnet corresponding to the position of the carbon steel plate is fixedly installed. The magnet and the carbon steel plate are magnetically attracted to each other, so as to realize the quick assembly and disassembly of the clamp body and the clamp fixing seat assembly.

[0008] Preferably, the upper mold assembly is further provided with a positioning pin, and the lower mold assembly is provided with a positioning pin sleeve that is adapted to and inserted into the positioning pin, for radial positioning of the upper mold assembly and the lower mold assembly when the clamp is closed.

[0009] Preferably, the rotating assembly further includes a set screw, which passes radially through the lower die assembly along the cylindrical pin, and the end of the set screw abuts against the outer wall of the cylindrical pin to limit the axial displacement of the cylindrical pin.

[0010] Preferably, the lower mold assembly includes a lower mold plate, the hook is fixed to the side of the lower mold plate corresponding to the hook plate, the positioning pin is embedded in the upper surface of the lower mold plate, and the carbon steel plate is fixed to the bottom surface of the lower mold plate.

[0011] Preferably, a fixing seat positioning pin is also fixedly provided on the base of the clamp fixing seat assembly, and a positioning hole adapted to be inserted into the bottom surface of the lower mold assembly is provided accordingly for quick positioning when the clamp body is assembled with the clamp fixing seat assembly.

[0012] Preferably, the upper mold assembly further includes a spring baffle, which is fixed to the lower surface of the upper mold plate. One end of the compression spring abuts against the spring baffle, and the other end abuts against the top of the pressure claw. The pressure claw fixing plate is provided with a guide hole adapted to the pressure claw, and the pressure claw can slide axially along the guide hole.

[0013] This invention also discloses a rapid clamping method for laser welding of electronic components, based on the aforementioned fixture for laser welding of electronic components, comprising the following steps: S1 Fixture Installation: Align and attract the carbon steel plate at the bottom of the lower mold assembly of the fixture body with the magnet on the base of the fixture fixing seat assembly to complete the quick installation and fixing of the fixture body; S2 Component Placement: Press the hook plate with one hand to release it from the hook engagement. The upper mold assembly rotates and opens around the cylindrical pin under the elastic restoring force of the torsion spring, placing the electronic component to be soldered into the preset position of the lower mold assembly. S3 Component Locking: Press the free end of the upper mold assembly with one hand to re-engage and lock the hook plate and hook. The pressure claw of the upper mold assembly elastically presses the electronic component to be welded under the action of the pressure spring, completing the clamping. S4 Fixture Replacement: After welding, simply lift the fixture body upwards to overcome the magnetic attraction and remove the fixture body from the fixture fixing assembly. Replace the fixture body with one corresponding to the electronic parts of different specifications. Repeat steps S1-S3 to complete the changeover clamping.

[0014] Preferably, in step S1, when the fixture body is installed, the fixture body is pre-positioned by inserting the positioning pin on the base into the positioning hole on the lower mold assembly, and then fixed by adsorption with the carbon steel plate by a magnet.

[0015] Preferably, in step S3, when the upper mold assembly is pressed down to close, the positioning pin on the upper mold assembly and the positioning pin on the lower mold assembly are engaged and fitted together to complete the mold closing positioning of the upper mold assembly and the lower mold assembly, and then the hook plate and the hook are engaged and locked.

[0016] The advantages of this invention compared to the prior art are: (1) This solution adopts a core structure design of single-sided rotation opening and closing + single-sided locking. Through the single-sided locking structure formed by the cooperation of the hook plate and the hook, the operator can complete the entire process of unlocking and locking the fixture with one hand, and the other hand can simultaneously complete the picking and placing of electronic parts, realizing the collaborative operation of both hands and solving the pain point of existing fixtures requiring two-hand operation; at the same time, with the torsion spring design of the rotating component, after unlocking, the upper mold can automatically spring open to the preset angle under the elastic restoring force of the torsion spring, without the need to manually lift the upper mold, simplifying the clamping operation steps and improving the efficiency of mass production.

[0017] (2) This solution adopts a magnetic tool-free quick-change structure. The carbon steel plate at the bottom of the lower mold assembly is magnetically attracted to the magnet on the fixture fixing base. No disassembly or assembly tools, air source and control equipment are required. The fixture body can be disassembled by simply lifting it upwards. The fixture can be fixed by aligning and fitting, which can shorten the fixture changeover time. At the same time, with the pre-positioning structure of the fixing base positioning pin and the lower mold positioning hole, the installation position accuracy of the fixture can be guaranteed to be consistent after each changeover. There is no need to recalibrate the welding station. It is suitable for the flexible welding production needs of multiple varieties and small batches of electronic parts, and reduces the time cost of product changeover.

[0018] (3) The upper mold assembly of this solution adopts an adaptive elastic pressing structure. The pressing spring provides a continuous and stable elastic pressing force to the pressing claw, which can adapt to the thickness deviation and processing tolerance of the parts to be welded. When the mold is closed, the elastic buffer completely avoids the problem of pressure damage and deformation caused by rigid pressing to precision electronic parts. At the same time, the elastic pressing can ensure that the parts are stably pressed in the welding position, avoiding displacement of the parts during the welding process, and effectively ensuring the consistency of welding accuracy.

[0019] (4) This solution adopts a modular design. The overall structure is divided into four major modules: upper mold assembly, lower mold assembly, rotating assembly, and fixture fixing base assembly. The number of parts is small, the processing and assembly difficulty is low, and the manufacturing cost is controllable. The rotating assembly restricts the axial movement of the cylindrical pin through the set screw, which can ensure the structural stability of the fixture during tens of thousands of repeated opening and closing processes and has a long service life. At the same time, each module is easy to disassemble and assemble, the replacement of vulnerable parts is convenient, the later maintenance cost is low, and it is suitable for industrial mass promotion and application.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of the embodiments of the present invention, "multiple" means at least two.

[0028] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances. Example

[0029] The fixture for laser welding of electronic components described in this embodiment includes a fixture body and a fixture fixing seat assembly D for fixing the fixture body. The fixture body includes an upper mold assembly A and a lower mold assembly B. The upper mold assembly A and the lower mold assembly B are hinged by a rotating assembly C, so that the upper mold assembly A can rotate and open relative to the lower mold assembly B about the rotation axis of the rotating assembly C.

[0030] One end of the upper mold assembly A is a hinged end connected to the rotating assembly C, and the other end is a free end. A hook plate 1 is fixed to the free end of the upper mold assembly A by screws. The lower mold assembly B has a hook 13 corresponding to the hook plate 1, which engages with the hook plate 1. The hook plate 1 and the hook 13 cooperate to form a single-sided locking structure, used to lock the relative positions of the upper mold assembly A and the lower mold assembly B when the clamp is closed. Unlike the existing double-sided clamping structure, this invention adopts a single-sided locking design, allowing the operator to complete locking and unlocking operations with one hand, eliminating the need for both hands to operate the clamp simultaneously. This frees up the other hand for handling electronic components 10, significantly improving operational efficiency.

[0031] The rotating assembly C includes a cylindrical pin 9 and a torsion spring 8. The cylindrical pin 9 is horizontally inserted at the hinge end of the upper mold assembly A and the corresponding hinge position of the lower mold assembly B, and the axis of the cylindrical pin 9 constitutes the rotation axis of the rotating assembly C. The torsion spring 8 is sleeved on the cylindrical pin 9, and its two ends abut against the lower surface of the upper mold assembly A and the upper surface of the lower mold assembly B, respectively, to provide an elastic restoring force to the upper mold assembly A in the opening direction. When the engagement between the latch plate 1 and the latch 13 is released, the elastic force of the torsion spring 8 can automatically lift the upper mold assembly A upward and rotate it to the open state, eliminating the need to manually lift the upper mold, further simplifying the operation steps and shortening the clamping time.

[0032] The upper mold assembly A also includes an upper template 3, a pressure claw 7, a pressure claw fixing plate 5, and a compression spring 6. The pressure claw 7 is mounted on the lower surface of the upper template 3 via the pressure claw fixing plate 5. The compression spring 6 is disposed between the pressure claw 7 and the upper template 3 and is used to provide the pressure claw 7 with an elastic clamping force toward the electronic component 10 to be welded.

[0033] In a preferred embodiment, the upper mold assembly A further includes a spring baffle 2, which is fixed to the lower surface of the upper mold plate 3 by screws. One end of the compression spring 6 abuts against the lower surface of the spring baffle 2, and the other end abuts against the top of the pressure claw 7. The pressure claw fixing plate 5 has a guide hole adapted to the pressure claw 7, and the upper end of the pressure claw 7 is limited within the guide hole and can slide axially along the guide hole. The elastic buffer design of the compression spring 6 avoids damage to the electronic components 10 caused by machining tolerances or mold closing stroke deviations, while ensuring stable clamping force for electronic components 10 of different thicknesses, thus improving the compatibility of the fixture. Furthermore, the upper mold assembly A is also vertically fixed with a positioning pin 4, and the lower mold assembly B is correspondingly provided with a positioning pin sleeve 12 that is adapted to and inserted into the positioning pin 4. This is used to radially position the upper mold assembly A and the lower mold assembly B when the fixture is closed, to ensure mold closing accuracy, to avoid deviation in the clamping position of the pressure claw 7, and to ensure the positional stability of the electronic component 10 during the welding process.

[0034] The lower mold assembly B includes a lower mold plate 11, and the hook 13 has a Z-shaped structure. The hook 13 is rotatably mounted on the side of the lower mold plate 11 corresponding to the hook plate 1 via a rotating shaft. The tightness of the engagement can be adjusted by rotation to adapt to different mold closing strokes. The positioning pin sleeve 12 is embedded in the upper surface of the lower mold plate 11 and is coaxially corresponding to the positioning pin 4 of the upper mold assembly A. The upper surface of the lower mold plate 11 is also provided with a contour positioning groove adapted to the electronic component 10 to be welded, which is used to pre-position the electronic component 10 and prevent the component from shifting during the welding process.

[0035] In this embodiment, a carbon steel plate 14 is fixedly installed on the bottom of the lower mold assembly B, i.e., the bottom surface of the lower mold plate 11. The fixture fixing seat assembly D includes a base, on which a magnet 17 corresponding to the position of the carbon steel plate 14 is fixedly installed. The magnet 17 is a strong permanent magnet, and the magnet 17 and the carbon steel plate 14 are magnetically attracted to each other, realizing the quick assembly and disassembly of the fixture body and the fixture fixing seat assembly D. Unlike the vacuum adsorption and screw locking methods in the prior art, this invention adopts a magnetic quick-change structure, which does not require an air source or screws. The fixture body can be disassembled by simply lifting, and it can be adsorbed and fixed by alignment, which greatly shortens the fixture changeover time and adapts to the flexible production needs of multi-specification parts.

[0036] Furthermore, a fixing seat positioning pin 15 is vertically fixed on the base of the fixture fixing seat assembly D, and a positioning hole that is adapted to be inserted into the bottom surface of the lower mold plate 11 of the lower mold assembly B is provided. This is used for quick positioning when the fixture body is assembled with the fixture fixing seat assembly D, ensuring consistent positional accuracy of each fixture installation, avoiding recalibration of the welding position after changing the model, and improving production efficiency.

[0037] This invention also discloses a rapid clamping method for laser welding of electronic components, based on the aforementioned fixture for laser welding of electronic components, specifically including the following steps: S1 Fixture Installation: Secure the base of the fixture fixing seat assembly D to the worktable of the laser welding machine with screws to complete the fixing and calibration of the base; align the carbon steel plate 14 at the bottom of the lower mold assembly B of the fixture body with the magnet 17 on the base, and at the same time insert the fixing seat positioning pin 15 on the base into the positioning hole on the bottom surface of the lower template 11. After the fixture body is pre-positioned, the magnet 17 and the carbon steel plate 14 are completely attracted and attached, completing the quick installation and fixing of the fixture body.

[0038] S2 Part Placement: The operator presses the end of the hook plate 1 with one hand to release the hook plate 1 from the hook 13. Under the elastic restoring force of the torsion spring 8, the upper mold assembly A rotates upward around the axis of the cylindrical pin 9 to the open state. The operator places the electronic part 10 to be welded into the contour positioning groove of the lower mold plate 11 with the other hand to complete the pre-positioning of the part.

[0039] S3 Part Locking: The operator presses the free end of the upper mold assembly A with one hand to overcome the elastic force of the torsion spring 8, causing the upper mold assembly A to rotate downward around the cylindrical pin 9 to close. During the closing process, the positioning pin 4 first inserts into the positioning pin sleeve 12 to complete the mold closing and positioning of the upper mold assembly A and the lower mold assembly B. After continuing to press down, the hook plate 1 and the hook 13 re-engage and lock. After the mold is closed and locked, the pressure claw 7, under the action of the pressure spring 6, elastically presses against the upper surface of the electronic part 10 to be welded, completing the clamping and fixing of the part. Then, the laser welding machine can be started to perform welding operations.

[0040] S4 Fixture Replacement: When it is necessary to replace the electronic component 10 of different specifications for welding, after the welding is completed, the operator can directly lift the fixture body upward to overcome the attraction force of the magnet 17 and remove the fixture body from the base; to replace the fixture body of the corresponding new specification electronic component, repeat steps S1-S3 to complete the changeover clamping, without the need to recalibrate the base position, which greatly shortens the changeover time.

[0041] The fixture and clamping method described in this embodiment solves the problems of existing fixtures requiring two-hand operation, large opening and closing stroke, and low clamping efficiency through a single-sided rotation opening and closing + single-hand locking and unlocking structural design. It enables simultaneous operation of the fixture with one hand and picking up and placing parts with the other hand, improving clamping efficiency by more than 50%. The magnetic quick-change structure solves the problems of inconvenient fixture changeover and the need for air source or tool assistance, making it suitable for the welding production needs of multiple varieties and small batches of electronic parts. At the same time, the elastic pressure claw structure avoids damage to parts and improves product yield. The overall structure is simple, easy to disassemble and maintain, and has low manufacturing cost, making it suitable for industrial mass production and application.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
