Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to welding equipment and a welding process for a probe. Background Art

[0002] RF chips are chips that can convert RF signals into digital signals. Each RF chip needs to undergo DC testing to ensure its electrical function. DC testing is to make the test machine and the probe card form a test loop, and directly contact the probe on the probe card with the chip to draw out the chip signal, and send the chip signal data to the test machine for analysis and judgment. In this way, bad chips can be filtered out before the packaging step to ensure the quality of the chip.

[0003] When performing DC testing on RF chips, a filter capacitor is generally added to the front end of the probe for filtering, and the closer to the needle tip, the better. Therefore, when making a probe card, a filter capacitor is welded and fixed to the front ends of two probes. However, since the probes are arranged compactly on the probe card, the spacing between the probes is very small, and the volume of the filter capacitor is larger than the spacing between the probes. Therefore, when welding and fixing the filter capacitor, it is necessary to fix the filter capacitor to the front end of the probe while extending the welding head to the front end of the probe for welding, which makes the welding process more difficult to operate and has lower welding efficiency. Summary of the invention

[0004] In order to improve the operational convenience of welding and fixing the filter capacitor to the front end of the probe, thereby improving the welding efficiency, the present application provides a welding device and a welding process for the probe.

[0005] The present application provides a welding device and welding process for a probe, which adopts the following technical solution:

[0007] By adopting the above technical scheme, the first positioning mechanism is used to help clamp and position the filter capacitor, and the second positioning mechanism is used to help lock and position a single probe, which helps to use a welding device to perform preliminary welding and fixation of a single probe and a filter capacitor separately, which helps to improve the convenience of welding and fixing the filter capacitor to the probe, and improves the welding efficiency; the positioning component is used to help position the probe and filter capacitor that have been preliminarily welded and inserted into the fixture, which helps to use the welding device to completely weld the probe and the filter capacitor, further improving the convenience of welding and fixing the filter capacitor to the probe, and further improving the welding efficiency.

[0008] In a specific feasible implementation manner, the first positioning mechanism includes a cylinder, a mounting groove is provided on the welding disk, the cylinder is arranged in the mounting groove, an I-shaped shaft disk is provided on the piston rod of the cylinder, a placement frame for placing the filter capacitor is provided on the I-shaped shaft disk, two groups of clamping assemblies for clamping the filter capacitor are provided in the mounting groove, and the two groups of the clamping assemblies are symmetrically arranged with the central axis of the I-shaped shaft disk as the symmetry axis.

[0009] By adopting the above technical solution, after the filter capacitor is placed on the placement rack, the operation of the cylinder helps to drive the I-beam shaft disk to rise and fall, thereby helping to drive the two sets of clamping components to clamp and position the filter capacitor placed on the I-beam shaft disk, facilitating the subsequent welding process.

[0010] In a specific feasible implementation scheme, the clamping assembly includes a first connecting rod, a second connecting rod, a third connecting rod and a clamping block, the first connecting rod is rotatably arranged in an installation groove, and one end of the first connecting rod is inserted in an I-beam disk, one end of the second connecting rod is hinged to an end of the first connecting rod away from the I-beam disk, the third connecting rod is rotatably arranged in the installation groove and is arranged parallel to the first connecting rod, one end of the third connecting rod is hinged to an end of the second connecting rod away from the first connecting rod, and the clamping block is arranged at an end of the third connecting rod away from the second connecting rod.

[0011] By adopting the above technical solution, after the filter capacitor is placed on the placement rack, the piston rod of the cylinder contracts, driving the I-beam shaft disk to descend, thereby driving the first connecting rod to rotate. While the first connecting rod rotates, it drives the second connecting rod to move upward along the fixed track. While the second connecting rod moves upward, it drives the third connecting rod to rotate, which helps to drive the clamping block to clamp and position the filter capacitor, facilitating the subsequent welding of the filter capacitor and the probe.

[0012] In a specific feasible implementation scheme, the second positioning mechanism includes a fixed lock seat, which is fixedly arranged on the welding disk, and two movable lock seats are movably arranged on the fixed lock seat, and a through hole for a probe to pass through is formed between the fixed lock seat and the two movable lock seats, and a transmission assembly for driving the two movable lock seats to move is arranged on the welding disk, and the transmission assembly is connected to the piston rod of the cylinder.

[0013] By adopting the above technical solution, after the probe is placed on the fixed lock seat, the contraction of the cylinder piston rod helps to drive the two movable lock seats to move along the fixed track through the transmission assembly, thereby helping the fixed lock seat to cooperate with the two movable lock seats to lock and position the probe, facilitating the subsequent welding process.

[0015] By adopting the above technical solution, after the probe is placed on the fixed lock seat, the piston rod of the cylinder contracts, driving the connecting rod to move downward synchronously, and at the same time, the guide rod drives the top support rod to move along the fixed track under the guidance of the guide groove, so that the top support rod slides on the bearing plate while driving the movable lock seat to move along the fixed track, thereby helping the fixed lock seat to cooperate with the two movable lock seats to lock and position the probe, which is convenient for the subsequent welding of the filter capacitor and the probe.

[0016] In a specific possible implementation scheme, the positioning assembly includes a placement seat, a positioning column and a rotating downward pressure cylinder, the placement seat is fixedly set on the welding disk, the positioning column is set on the placement seat, and the rotating downward pressure cylinder is set on the welding disk and located on one side of the placement seat.

[0017] By adopting the above technical solution, after the probe and filter capacitor that have been preliminarily welded are inserted into the jig, the jig is placed in a fixed position on the placement seat, and the positioning column and the rotating downward pressure cylinder are used to help position the jig, thereby helping to complete the complete welding of the probe and the filter capacitor.

[0019] By adopting the above technical solution, the use of a rotating cylinder helps to drive the rotation of the welding disk, thereby helping to adjust the welding position, and the use of a partition baffle helps to separate the surface of the welding disk into two areas, making it convenient to place another group of probes and filter capacitors inserted into the fixture on the welding disk while performing preliminary welding on one group of probes and filter capacitors, thereby helping to improve welding efficiency.

[0020] A welding process for a probe, based on the above-mentioned welding device for a probe, comprises the following steps:

[0021] Step 1: Positioning before welding: before welding, the filter capacitor is clamped and positioned using the first positioning mechanism, and the probe is locked and positioned using the second positioning mechanism, so that the relative position of the probe and the filter capacitor remains unchanged;

[0022] Step 2: Preliminary welding: using a welding device to perform preliminary welding on the probe and filter capacitor after positioning, so that the probe and filter capacitor are welded and fixed;

[0023] Step 3: Probe assembly: insert the initially welded probe and filter capacitor into the set position of the fixture so that the filter capacitor is located at the set position;

[0024] Step 4: Complete welding: Use the welding device to weld the filter capacitor at the set position to another probe to complete the entire welding process.

[0025] By adopting the above technical solution, a single probe and a filter capacitor are individually preliminarily welded and fixed using a welding device, which helps to improve the convenience of welding and fixing the filter capacitor to the probe, thereby helping to improve the welding efficiency; using the welding device to completely weld the probe and filter capacitor that have been inserted into the fixture and preliminarily welded helps to further improve the convenience of welding and fixing the filter capacitor to the probe, further improving the welding efficiency.

[0047] Reference Figure 1 and Figure 3 When the filter capacitor and the probe are positioned, the operator uses the welding device 5 to perform preliminary welding on the filter capacitor and the probe, thereby welding and fixing the filter capacitor to the probe.

[0048] Reference Figure 4 and Figure 6 After the preliminary welding is completed, the piston rod of the cylinder 7 extends, driving the connecting rod 141 to move upward synchronously, so that the top support rod 143 and the movable lock seat 12 move upward along the fixed track under the dual drive of the slider 18 and the guide rod 144.

[0049] Reference Figure 4 and Figure 6When the piston rod of the cylinder 7 extends, it drives the I-beam disk 8 and the placement rack 9 to move upward, thereby driving the two first connecting rods 101 to rotate synchronously.

When the third connecting rod 103 rotates, it drives the clamping block 104 to release the clamping of the filter capacitor, so that the placement rack 9 lifts the filter capacitor and the probe that have been preliminarily welded, which is convenient for the operator to take out the filter capacitor and the probe that have been preliminarily welded.

[0050] Reference Figure 3 The positioning assembly 6 includes a placement seat 61, a positioning column 62 and a rotary downward pressing cylinder 63. In this embodiment, two positioning columns 62 and two rotary downward pressing cylinders 63 are each provided.

[0051] Reference Figure 1 and Figure 3 After taking out the filter capacitor and probe that have been preliminarily welded, the operator inserts the probe and filter capacitor that have been preliminarily welded into the set position of the jig, so that the filter capacitor is fixed in the set position. The operator places the jig with the probe and filter capacitor inserted on the placement seat 61, locates the placement position of the jig through two positioning columns 62, and presses the jig through two rotating downward cylinders 63, which helps to improve the stability of the probe and filter capacitor during the welding process. After the jig is positioned and pressed, the operator uses the welding device 5 to weld the filter capacitor at the set position with another probe to complete the entire welding process.

[0052] The embodiment of the present application also discloses a welding process based on the above welding equipment, comprising the following steps:

[0053] Step 1: Positioning before welding. The operator first places the filter capacitor on the placement rack 9, and then places the probe card on the two fixed lock seats 11. The piston rod of the cylinder 7 contracts, driving the I-shaped shaft plate 8 and the placement rack 9 to move downward, thereby driving the two first connecting rods 101 to rotate synchronously. When the first connecting rod 101 rotates, it drives the second connecting rod 102 to move up along the fixed track. When the second connecting rod 102 moves up, it drives the third connecting rod 103 to rotate. When the third connecting rod 103 rotates, it drives the clamping block 104 to perform the filter capacitor. Clamping and positioning; at the same time, the connecting rod 141 is driven to move downward synchronously, so that the slider 18 slides along the slide rail 17, and the guide rod 144 moves along the guide groove 16, so that the top support rod 143 and the movable lock seat 12 move downward along the fixed track under the dual drive of the slider 18 and the guide rod 144, which helps to make the two movable lock seats 12 fit with the top surface of the fixed lock seat 11, so that the fixed lock seat 11 cooperates with the two movable lock seats 12 to lock and position the probe, which helps to fix the probe and the filter capacitor in the welding position.

[0054] Step 2: Preliminary welding. After the filter capacitor and the probe are positioned, the operator uses the welding device 5 to perform preliminary welding on the filter capacitor and the probe, thereby welding and fixing the filter capacitor to the probe. When the probe and the filter capacitor are preliminarily welded, the piston rod of the cylinder 7 extends, driving the connecting rod 141 to move up synchronously, so that the top support rod 143 and the movable lock seat 12 move up along the fixed track under the dual drive of the slider 18 and the guide rod 144, and the two movable lock seats 12 move away from each other while moving up, thereby releasing the locking of the probe. At the same time, the I-shaped shaft disk 8 and the placement rack 9 are driven to move up, thereby driving the two first connecting rods 101 to rotate synchronously, the first connecting rod 101 drives the second connecting rod 102 to move down along the fixed track when rotating, the second connecting rod 102 drives the third connecting rod 103 to rotate when moving down, and the third connecting rod 103 drives the clamping block 104 to release the clamping of the filter capacitor when rotating, so that the placement rack 9 lifts the filter capacitor and the probe that have been preliminarily welded, which is convenient for the operator to take out the filter capacitor and the probe that have been preliminarily welded.

[0055] Step 3: Probe assembly. After taking out the filter capacitor and probe that have been preliminarily welded, the operator inserts the probe and filter capacitor that have been preliminarily welded into the set position of the fixture, so that the filter capacitor is fixed in the set position.

[0056] Step 4: Complete welding, the operator places the jig with the probe and filter capacitor inserted on the placement seat 61, locates the placement position of the jig through two positioning columns 62, and presses the jig through two rotating downward pressure cylinders 63, which helps to improve the stability of the probe and filter capacitor during the welding process. After the jig is positioned and pressed, the operator uses the welding device 5 to weld the filter capacitor at the set position with another probe to complete the entire welding process.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
