Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and in particular to a quick-release mechanism for welding heads and a welding device. Background Technology

[0002] Soldering is a common welding method in industry. Solder balls are supplied to the welding head by a feeding assembly. The welding head guides the solder balls so that they fall onto the workpiece at the position where they need to be welded. The laser generating mechanism emits a laser beam at the solder balls, causing them to melt and thus completing the soldering process.

[0003] In the existing technology, the welding head is fixed to the feeding assembly with screws, and the welding head needs to be removed manually by unscrewing the screws, which makes the replacement efficiency of the welding head too low. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a quick-release mechanism for welding heads and a welding device, which can improve the efficiency of welding head replacement.

[0005] In a first aspect, embodiments of the present invention provide a quick-release mechanism for a soldering head, comprising: a feeding assembly including a material cylinder and a movable component; the material cylinder having a discharge hole for feeding solder balls, the inner wall of the discharge hole having a movable hole, and the movable component disposed in the movable hole; a soldering head inserted into the discharge hole and having a mating groove, the mating groove being able to mate with the movable component to restrict the soldering head from exiting the movable hole; and a quick-release assembly including a quick-release driver and a movable sleeve connected to each other; the movable sleeve being relatively movably fitted onto the material cylinder and having a clearance groove facing the material cylinder; the quick-release driver being able to drive the movable sleeve to move from a first position to a second position; when the movable sleeve is in the first position, the movable sleeve abuts against the movable component to keep the movable component engaged with the mating groove; when the movable sleeve is in the second position, the clearance groove is opposite to the movable component to allow the movable component to be received in the clearance groove, thereby allowing the soldering head to exit the discharge hole.

[0006] The quick-release mechanism for welding heads provided in the first aspect of the present invention has at least the following beneficial effects: By creating a movable hole in the inner wall of the discharge port of the barrel, and installing a movable part within the movable hole, the welding head is inserted into the discharge port and a mating groove is provided. This allows the welding head to be installed and removed through the engagement of the movable part and the mating groove. Simultaneously, a quick-release actuator and a movable sleeve are provided. The movable sleeve is movably fitted onto the barrel and has a clearance groove facing the barrel. When the movable sleeve is in the first position, it abuts against the movable part, keeping the movable part engaged with the mating groove and preventing the welding head from exiting the movable hole, thus ensuring the welding head is in a working state. When the welding head needs to be replaced, the quick-release actuator can move the movable sleeve from the first position to the second position, causing the clearance groove to align with the movable part. The movable part can then be accommodated in the clearance groove, allowing the welding head to exit the discharge port, thus ensuring the welding head is in a detachable state. This improves the automation level and efficiency of welding head replacement.

[0007] In one embodiment of this implementation, the quick-release driver is also capable of driving the movable sleeve to move from the second position to the first position.

[0008] In one embodiment of this implementation, the movable component includes a plurality of balls, and the number of movable holes is a plurality of balls, each ball being disposed in a corresponding movable hole.

[0009] In one embodiment of this implementation, the plurality of movable holes are spaced apart in the circumferential direction.

[0010] In one embodiment of this implementation, the clearance groove is an annular groove, which can simultaneously accommodate multiple of the balls.

[0011] In one embodiment of this implementation, the mating groove is an annular groove, so that it can simultaneously mate with multiple of the balls.

[0012] In one embodiment of this implementation, the movable sleeve has an assembly hole, the material cylinder slides in conjunction with the assembly hole, and the clearance groove is formed on the inner wall of the assembly hole. When the movable sleeve is in the first position, the inner wall of the assembly hole abuts against the movable part.

[0013] In one embodiment of this implementation, the feeding assembly includes a limiting member disposed on the material cylinder and capable of abutting against the movable sleeve to support the movable sleeve.

[0014] In one embodiment of this implementation, a groove is provided on the outer periphery of the barrel, and the limiting member is constructed as a retaining ring that engages with the groove.

[0015] Secondly, embodiments of the present invention provide a welding apparatus, which includes a laser generating mechanism and a quick-release mechanism for a welding head as described in any embodiment of the first aspect, wherein the laser generating mechanism is used to emit a laser to the solder ball inside the welding head of the quick-release mechanism.

[0016] The welding apparatus provided by the second aspect of the present invention has at least the following beneficial effects: By incorporating the welding apparatus of the first aspect embodiment into the welding apparatus, the corresponding welding head can be quickly replaced according to welding requirements, resulting in high replacement efficiency and improving welding efficiency.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a welding apparatus 1000 according to one embodiment of the present invention. The present invention provides a welding apparatus 1000, which includes a laser generating mechanism 200 and a quick-release welding head mechanism 100. The laser generating mechanism 200 emits a laser beam towards the solder ball within the welding head 20 of the quick-release welding head mechanism 100. It is understood that the welding head 20 of the quick-release welding head mechanism 100 can be aligned with the workpiece, causing the solder ball to fall to the welding position on the workpiece. The laser generating mechanism 200 emits a laser beam towards the solder ball, causing the solder ball to melt, thereby completing the soldering.

[0026] Specifically, the laser generating mechanism 200 includes a laser generator 210 and a motion adjustment module 220. The motion adjustment module 220 can drive the laser generator 210 to move in three axes in order to adjust the spatial position of the laser generator 210 so that the laser emitted by the laser generator 210 can be aligned with the solder ball and at a suitable distance from the solder ball.

[0027] Specifically, the welding device 1000 is used in ball grid array packaging (BGA), and can be applied to the welding of chip products and circuit board products.

[0028] By incorporating the welding device 1000 of the present invention into the welding device 1000, the corresponding welding head 20 can be quickly replaced according to welding requirements, resulting in high replacement efficiency and improving welding efficiency.

[0029] The quick-release mechanism 100 for the welding head in the welding apparatus 1000 provided in the embodiments of the present invention will be described in detail below.

[0030] Please see Figure 4 , Figure 6 and Figure 7 , Figure 4 yes Figure 3 A schematic diagram of the structure of the feeding assembly 10, the welding head 20, and the quick-release assembly 30; Figure 6 yes Figure 4 A schematic diagram of the structure of part of the feeding component 10 in the disassembled state; Figure 7 yes Figure 4 This is a structural schematic diagram of the feeding assembly 10 from another perspective in its disassembled state. An embodiment of the present invention provides a quick-release mechanism 100 for a solder head, comprising a feeding assembly 10, a solder head 20, and a quick-release assembly 30. The feeding assembly 10 includes a barrel 11 and a movable member 12. The barrel 11 has a discharge hole 111 for feeding solder balls, and a movable hole 112 is formed in the inner wall of the discharge hole 111. The movable member 12 is disposed in the movable hole 112. The solder head 20 is inserted into the discharge hole 111 and has a mating groove 201. The mating groove 201 can mate with the movable member 12 to prevent the solder head 20 from exiting the movable hole 112. The quick-release assembly 30 includes a quick-release driver 31 and a movable sleeve 32 connected to each other. The movable sleeve 32 is movably fitted onto the barrel 11 and has a clearance groove 321 facing the barrel 11. The quick-release driver 31 can drive the movable sleeve 32 to move from a first position to a second position.

[0031] When the movable sleeve 32 is in the first position, the movable sleeve 32 abuts against the movable member 12 so that the movable member 12 is engaged with the mating groove 201; when the movable sleeve 32 is in the second position, the clearance groove 321 is opposite to the movable member 12 so that the movable member 12 can be accommodated in the clearance groove 321, thereby allowing the welding head 20 to exit the discharge hole 111.

[0032] Specifically, the welding head 20 has a welding hole 202, which is connected to the discharge hole 111, so that the solder ball discharged from the discharge hole 111 can enter the welding hole 202 and fall from the bottom of the welding hole 202 onto the welding position of the workpiece.

[0033] Please refer to the following for details. Figure 5 , Figure 5 yes Figure 4 A schematic diagram of the quick-release driver 31 in the quick-release assembly 30 is shown. The quick-release driver 31 includes a vertical drive member 311 and a push block 312. The vertical drive member 311 is connected to the push block 312 and can drive the push block 312 to move vertically. The push block 312 can abut against the movable sleeve 32 to push the movable sleeve 32 to move vertically under the drive of the vertical drive member 311. In this embodiment, the push block 312 can drive the movable sleeve 32 to move upward, so that the movable sleeve 32 moves from a first position to a second position, so that the welding head 20 switches from the working state to the detachable state.

[0034] A movable hole 112 is formed in the inner wall of the discharge hole 111 of the barrel 11, and a movable part 12 is set in the movable hole 112. The welding head 20 is inserted into the discharge hole 111, and a mating groove 201 is formed, so that the welding head 20 can be disassembled and assembled through the engagement of the movable part 12 and the mating groove 201. At the same time, a quick-release driver 31 and a movable sleeve 32 are provided. The movable sleeve 32 is relatively movable and fitted onto the barrel 11, and a clearance groove 321 facing the barrel 11 is formed. When the movable sleeve 32 is in the first position, the movable sleeve 32 and the movable part 12 are in a certain position. The quick-release actuator 31 can abut against the movable part 12 to keep it engaged with the mating groove 201, restricting the welding head 20 from exiting the movable hole 112. The welding head 20 is in the working state. When the welding head 20 needs to be replaced, the quick-release actuator 31 can drive the movable sleeve 32 to move from the first position to the second position, so that the clearance groove 321 is opposite to the movable part 12. The movable part 12 can be received in the clearance groove 321, thereby allowing the welding head 20 to exit the discharge hole 111. The welding head 20 is in the detachable state, thereby improving the automation level of welding head 20 replacement and improving replacement efficiency.

[0035] In one embodiment of this implementation, please refer to Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the quick-release mechanism 100 for the welding head in the welding apparatus 1000 is shown. The quick-release mechanism 100 includes a mounting base 60 and a vertical drive module 70. The feeding assembly 10 and the quick-release driver 31 are both mounted on the mounting base 60. The vertical drive module 70 is connected to the mounting base 60 and can drive the mounting base 60 to move the laser generating mechanism 200 and the welding head 20 synchronously in the vertical direction, so that the welding head 20 can be welded and replaced.

[0036] Please refer to the following for details. Figure 1 The motion adjustment module 220 of the laser generating mechanism 200 is mounted on the mounting base 60 to facilitate maintaining the consistency of the welding process.

[0037] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 A schematic diagram of the disassembled state of the replacement table 40 carrying the welding head 20 in the welding apparatus 1000. The welding head quick-release mechanism 100 includes the replacement table 40 and the electromagnetic adsorption component 50. The top side of the replacement table 40 has multiple receiving holes 401 for accommodating the welding head 20 to be replaced. The electromagnetic adsorption component 50 is installed in the receiving holes 401 and can be energized to pick up the welding head 20 on the material cylinder 11.

[0038] Specifically, in order to install the electromagnetic adsorption component 50, a fixing hole is provided on the bottom wall of the receiving hole 401. The electromagnetic adsorption component 50 is installed in the fixing hole and is flush with the bottom wall of the receiving hole 401.

[0039] Specifically, the electromagnetic adsorption component 50 can be an electromagnet.

[0040] In this embodiment, after the quick-release driver 31 drives the movable sleeve 32 to the second position, the vertical driver can drive the mounting base 60 to move the welding head 20 vertically into the receiving hole 401, so that the welding head 20 can be separated from the discharge hole 111 under the electromagnetic force of the electromagnetic adsorption component 50 and accommodated in the receiving hole 401, thereby completing the disassembly of the welding head 20.

[0041] In one embodiment of this implementation, please refer to Figure 3 , Figure 6 and Figure 7 To further improve the automation of welding head 20 replacement, quick-release driver 31 can also drive movable sleeve 32 from the second position to the first position. This configuration allows the quick-release assembly 30 to switch the welding head 20 from a detachable state to a working state, improving replacement efficiency.

[0042] Specifically, in this embodiment, the push block 312 is fixedly connected to the movable sleeve 32 so that it can move synchronously under the drive of the vertical drive member 311, thereby realizing the switching of the welding head 20 between the detachable state and the working state.

[0043] In this embodiment, when the vertical driver drives the mounting base 60 to move the material cylinder 11 to cooperate with the welding head 20 on the replacement table 40 (the welding head 20 on the replacement table 40 is inserted into the discharge hole 111 of the material cylinder 11), the quick-release driver 31 drives the movable sleeve 32 to move from the second position to the first position, so that the welding head 20 is fixed with the material cylinder 11, thereby completing the replacement.

[0044] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 To improve the connection strength between the welding head 20 and the barrel 11 during operation, the movable component 12 includes multiple balls 121 and multiple movable holes 112, with each ball 121 positioned in a corresponding movable hole 112. It is understood that, supported by the movable sleeve 32, the multiple balls 121 can fully contact the welding head 20, thereby improving the connection strength between the welding head 20 and the barrel 11.

[0045] In this embodiment, the discharge hole 111 extends vertically, and the movable hole 112 extends horizontally.

[0046] In this embodiment, the movable hole 112 is a circular hole with a diameter slightly larger than that of the ball 121.

[0047] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 Multiple movable holes 112 are spaced apart in the circumferential direction. This arrangement ensures that the multiple balls 121 are subjected to uniform force with the welding head 20, which helps to improve welding quality and consistency.

[0048] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 The clearance groove 321 is an annular groove to accommodate multiple balls 121 simultaneously. It is understood that constructing the clearance groove 321 as an annular groove allows the movable sleeve 32 to be installed on the barrel 11 at any circumferential relative angle, reducing assembly difficulty. Moreover, the annular groove is easier to form, which helps to reduce costs.

[0049] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 The mating groove 201 is an annular groove to allow simultaneous mating with multiple balls 121. It is understood that constructing the mating groove 201 as an annular groove allows the welding head 20 to be mounted on the barrel 11 at any circumferential relative angle, reducing replacement difficulty, facilitating automation, and making the molding of the mating groove 201 easier, thus helping to reduce costs.

[0050] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 The movable sleeve 32 has an assembly hole 322, and the barrel 11 slides into the assembly hole 322. A clearance groove 321 is formed on the inner wall of the assembly hole 322. When the movable sleeve 32 is in the first position, the inner wall of the assembly hole 322 abuts against the movable part 12. It can be understood that, since the clearance groove 321 is formed on the inner wall of the assembly hole 322, when the movable sleeve 32 is in the first position, the inner wall of the assembly hole 322 abuts against the side of the movable part 12 facing away from the welding head 20, so that the movable part 12 and the mating groove 201 are engaged, and the welding head 20 is in the working state. When the movable sleeve 32 is in the second position, the mating groove 201, which is concave relative to the inner wall of the assembly hole 322, is opposite to the movable part 12, so that the movable part 12 has the space to move away from the mating groove 201, thus making the welding head 20 detachable. With this configuration, the movable sleeve 32 can switch between a first position and a second position by sliding relative to the material cylinder 11, and can abut against the movable part 12 using the inner wall of the assembly hole 322 so that the movable part 12 and the mating groove 201 can maintain a fit.

[0051] In this embodiment, an annular boss 114 is provided on the outer periphery of the top end of the barrel 11, and the annular boss 114 slides in conjunction with the assembly hole 322.

[0052] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 The feeding assembly 10 includes a limiting member 13, which is disposed in the feed cylinder 11 and can abut against the movable sleeve 32 to support the movable sleeve 32. This arrangement serves two purposes: firstly, the limiting member 13 can limit the movable sleeve 32, preventing it from leaving the feed cylinder 11 under gravity; secondly, when using elastic elements such as springs for resetting, the limiting member 13 can provide reliable support.

[0053] In this embodiment, the quick-release driver 31 is used to drive the movable sleeve 32 to move from the first position to the second position. The feeding assembly 10 includes an elastic reset member (not shown), which is connected to the movable sleeve 32 and is used to drive the movable sleeve 32 to move from the second position to the first position.

[0054] Specifically, the second position is located above the first position. The quick-release actuator 31 drives the movable sleeve 32 to move upward, from the first position to the second position. When a reset is required, the quick-release actuator 31 disengages from the movable sleeve 32, and the elastic reset member applies an elastic force to the movable sleeve 32, causing the movable sleeve 32 to move downward, from the second position to the first position.

[0055] In one embodiment of this implementation, please refer to Figure 6 and Figure 7 In order to reduce the installation difficulty of the limiting member 13 and to enable the limiting member 13 to abut against the bottom side of the movable sleeve 32 to form support, the outer periphery of the material cylinder 11 is provided with a slot 113, and the limiting member 13 is constructed as a retaining ring that is engaged with the slot 113.

[0056] In one embodiment of this implementation, please refer to Figure 1 , Figure 3 , Figure 8 and Figure 9 , Figure 8 yes Figure 4 A schematic diagram of the structure of part of the feeding component 10 in the disassembled state; Figure 9 yes Figure 4This is a partial structural diagram of the feeding assembly 10 from another perspective in its disassembled state. The feeding assembly 10 includes a base 14, a top cover 15, a dispensing tray 16, a rotary driver 17, and a mounting plate 18. The mounting plate 18 is fixed on the mounting base 60, and the base 14, top cover 15, and rotary driver 17 are all mounted on the mounting plate 18. The base 14 and top cover 15 enclose a mounting cavity. The dispensing tray 16 is disposed within the mounting cavity and connected to the output shaft 171 of the rotary driver 17, so that it can rotate about an axis parallel to the vertical direction under the drive of the rotary driver 17. A hopper 151 is provided on the top side of the top cover 15, and a storage cavity 152 communicating with the mounting cavity is provided on the bottom side of the top cover 15. The hopper 151 communicates with the storage cavity 152 for adding solder balls to the storage cavity 152. The dispensing tray 16 has multiple ball grooves 161 distributed circumferentially. The diameter of the ball grooves 161 is slightly larger than the diameter of the solder ball, so that the solder ball can enter the ball groove 161 and be driven to rotate by the dispensing tray 16. The base 14 has a through hole 141 that communicates with the discharge hole 111. When the solder ball on the dispensing tray 16 is on the top side of the through hole 141, the solder ball can pass through the through hole 141 and enter the discharge hole 111 and the soldering hole 202 in sequence, thereby completing the discharge of the solder ball.

[0057] Specifically, the base 14 has a first light-transmitting hole 142, and the top cover 15 has a second light-transmitting hole 153. The second light-transmitting hole 153, the first light-transmitting hole 142, the material passage hole 141, and the soldering hole 202 are connected in sequence in the vertical direction. The laser generator 210 of the laser generating mechanism 200 is located on the top side of the top cover 15 so that it can generate a laser in the vertical direction. The laser can pass through the second light-transmitting hole 153, the first light-transmitting hole 142, the material passage hole 141, and the soldering hole 202 in sequence, and melt the solder ball located at the bottom of the soldering hole 202, thereby completing the soldering.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
