Description

Technical Field

[0001] This invention relates to the field of chip testing technology, and in particular to a tapping device and its usage method. Background Technology

[0002] After the visual inspection of CSP (Chip Scale Package) products, a robotic arm is typically used to pick up the chips and place them into the grooves of a tray. Due to limitations in the robotic arm's movement precision, chips cannot always be perfectly centered within their corresponding grooves, leading to issues such as tray misalignment and tilting during subsequent testing, affecting testing efficiency and accuracy. To avoid these problems, existing technology involves manually moving misaligned chips to the center of their corresponding grooves; however, this method is inefficient and also impacts the efficiency of subsequent tests. Summary of the Invention

[0003] The purpose of this invention is to provide a tapping device and a method of use that can automatically adjust the position of a chip, thereby effectively improving the efficiency of chip position adjustment and thus improving the efficiency of subsequent testing.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] A striking device, comprising:

[0006] At least one cylinder; the cylinder having a piston rod disposed opposite to a side wall of a tray;

[0007] An intake valve, connected to the interior of the cylinder, is used to introduce gas into the cylinder to push the piston rod to extend and retract along its own axis, causing the piston rod to strike the side wall of the tray and adjust the position of the chip inside the tray.

[0008] Optionally, the number of cylinders is two, and the axes of the piston rods of the two cylinders intersect perpendicularly.

[0009] Optionally, the striking device further includes a controller electrically connected to the air intake valve, used to control the air intake valve to open and close at a preset frequency, so that the piston rod strikes the side wall of the tray at the preset frequency.

[0010] Optionally, the preset frequency is 3 times / second to 10 times / second.

[0011] Optionally, the controller is also electrically connected to a robotic arm, which is used to place the chip in the tray and send a chip placement signal to the controller, so that the controller controls the opening and closing of the air intake valve according to the chip placement signal.

[0012] Optionally, the cylinder is a single-acting telescopic cylinder.

[0013] Optionally, the cylinder is further provided with a piston connected to the piston rod; each cylinder is provided with an intake valve, and the intake valve is connected to a chamber on either side of the piston.

[0014] Optionally, the cylinder is a double-acting telescopic cylinder.

[0015] Optionally, the cylinder is further provided with a piston connected to the piston rod; each cylinder is provided with two intake valves, and the two intake valves are respectively connected to the chambers on both sides of the piston.

[0016] Optionally, the tray has a plurality of grooves, each groove being used to accommodate one of the chips.

[0017] On the other hand, the present invention also provides a method of using the striking device as described above, comprising:

[0018] The intake valve is opened and closed at a preset frequency by the industrial control software, causing the piston rod to tap the side wall of the tray at the preset frequency to adjust the position of the chip inside the tray.

[0019] Optionally, the striking device further includes a controller electrically connected to the air intake valve and the robotic arm; the method of use includes:

[0020] The robotic arm places the chip into the tray and sends a chip placement signal to the controller;

[0021] After receiving the chip-ready signal, the controller controls the air intake valve to open and close at the preset frequency; and

[0022] After a preset time, the controller controls the intake valve to close, so that the piston rod stops striking the side wall of the tray.

[0023] Optionally, the preset duration is 1 to 10 seconds.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] This invention provides a striking device and its method of use. Gas is introduced into a cylinder via an air inlet valve, causing a piston rod within the cylinder to extend and retract along its own axis. This piston rod strikes the side wall of a tray, thereby adjusting the position of the chip within the tray.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0032] Combined with appendix Figures 1-4As shown, this embodiment provides a striking device, including at least one cylinder 210 and an air intake valve 220. The cylinder 210 has a piston rod 211, which is disposed opposite to the side wall of a tray 110. The air intake valve 220 communicates with the interior of the cylinder 210 and is used to introduce gas into the cylinder 210 to push the piston rod 211 to extend and retract along its own axial direction, so that the piston rod 211 strikes the side wall of the tray 110, thereby adjusting the position of the chip 100 in the tray 110. Optionally, the tray 110 is provided with a plurality of grooves 111, each groove 111 for accommodating one chip 100.

[0033] Specifically, when the chip 100 is placed in the tray 110, the air intake valve 220 can be opened and closed multiple times to control the piston rod 211 to repeatedly strike the side wall of the tray 110, thereby causing the chip 100 to move in the corresponding groove 111 on the tray 110, thus ensuring that the chip 100 is accurately placed in the tray 110 and that the chip 100 is located at the center of the corresponding groove 111.

[0034] Compared to existing technologies that rely on manual adjustment of misaligned chips, this embodiment utilizes the combination of the air intake valve 220 and the cylinder 210 to automatically adjust the chip's position, thereby effectively improving the efficiency of chip position adjustment and consequently enhancing the efficiency of subsequent testing.

[0035] It is understood that in some embodiments, such as Figure 2 As shown, there are two cylinders 210, and the axes of the piston rods 211 of the two cylinders 210 intersect perpendicularly. In this case, the piston rods 211 of the two cylinders 210 can simultaneously or sequentially strike the side wall of the tray 110 in two perpendicular directions (i.e., the X direction and the Y direction), further improving the efficiency of adjusting the position of the chip 100, but the present invention is not limited thereto.

[0036] In other embodiments, the tapping device further includes a controller (not shown in the figure); the controller is electrically connected to the air intake valve 220 and is used to control the air intake valve 220 to open and close at a preset frequency, so that the piston rod 211 taps the side wall of the tray 110 at the preset frequency, thereby further improving the automation level of the tapping device. Optionally, the preset frequency is 3 times / second to 10 times / second to ensure the efficiency of adjusting the position of the chip 100; preferably, the preset frequency is 5 times / second, but the present invention is not limited thereto.

[0037] In addition, the controller is electrically connected to a robotic arm (not shown in the figure), which is used to place the chip 100 in the tray 110 and send a chip placement signal to the controller so that the controller controls the opening and closing of the air intake valve 220 according to the chip placement signal.

[0038] Specifically, after receiving the chip placement signal, the controller controls the air intake valve 220 to open and close at the preset frequency. This allows the piston rod 211 to tap the side wall of the tray 110 at the preset frequency after the robotic arm places the chip 100 into the tray 110, thereby adjusting the position of the chip 100. Further, after a preset time period, once the position adjustment of the chip 100 is complete, the controller also controls the air intake valve 220 to close, at which point the piston rod 211 stops tapping the side wall of the tray 110. Optionally, the preset time period is 1 to 10 seconds to ensure sufficient tapping time of the piston rod 211 on the tray 110, thus ensuring enough time to adjust the position of the chip 100. Preferably, the preset time period is 5 seconds, but this invention is not limited to this.

[0039] It is understood that when the robotic arm places the chip 100 into the tray 110, the controller also controls the air intake valve 220 to close, so as to prevent the piston rod 211 from hitting the tray 110 and affecting the operation of the robotic arm placing the chip 100.

[0040] Specifically, the intake valve 220 is also connected to a gas source 230 for storing gas, so as to allow gas to be introduced into the cylinder 210. The cylinder 210 is also provided with a piston (not shown in the figure) connected to the piston rod 211; the piston divides the internal space of the cylinder 210 into two non-communicating chambers, namely a rod chamber (containing the piston rod 211) and a rodless chamber (without the piston rod 211).

[0041] In some embodiments, such as Figures 1 to 4 As shown, the cylinder 210 can be a double-acting telescopic cylinder; in this case, each cylinder 210 is provided with two intake valves 220, and the two intake valves 220 are respectively connected to the chambers on both sides of the piston. Specifically, one of the two intake valves 220 is connected to the rod chamber, and the other is connected to the rodless chamber, and the two are opened and closed alternately.

[0042] If the intake valve 220, which is connected to the rod chamber, is opened and gas is introduced into the rod chamber, then the intake valve 220, which is connected to the rodless chamber, is closed. In this case, the gas introduced into the rod chamber will push the piston inward, that is, move away from the tray 110, so that the piston rod 211 moves away from the tray 110, that is, retracts along its own axis.

[0043] If the intake valve 220 connected to the rod chamber is closed, the intake valve 220 connected to the rodless chamber is opened and gas is introduced into the rodless chamber. In this case, the gas introduced into the rodless chamber will push the piston outward, that is, move towards the side closer to the tray 110, so that the piston rod 211 moves towards the side closer to the tray 110, that is, extends along its own axis to strike the tray 110.

[0044] In some other embodiments, the cylinder 210 may be a single-acting telescopic cylinder; in this case, each cylinder 210 is provided with an intake valve 220, and the intake valve 220 is connected to a chamber on either side of the piston.

[0045] Specifically, if the intake valve 220 is connected to the rod chamber, a spring that abuts against the piston can be installed in the rodless chamber. When the intake valve 220 opens to introduce gas into the rod chamber, the gas pushes the piston inward, i.e., away from the tray 110, and compresses the spring, thereby causing the piston rod 211 to retract along its own axial direction. When the intake valve 220 closes to stop introducing gas into the rod chamber, the spring extends and pushes the piston outward, i.e., closer to the tray 110, thereby causing the piston rod 211 to extend along its own axial direction and strike the tray 110. Optionally, the spring can also be replaced by other reset devices.

[0046] If the intake valve 220 is connected to the rodless chamber, a spring that the piston abuts can be installed in the rod chamber. When the intake valve 220 is open to introduce gas into the rodless chamber, the gas pushes the piston outward, i.e., towards the side closer to the tray 110, and compresses the spring, thereby causing the piston rod 211 to extend along its own axis and strike the tray 110; when the intake valve 220 is closed to stop introducing gas into the rodless chamber, the spring extends and pushes the piston inward, i.e., away from the tray 110, thereby causing the piston rod 211 to retract along its own axis.

[0047] Furthermore, other components of the cylinder 210 (such as exhaust valves) are similar to those in the prior art and will not be described in detail here.

[0048] Based on the same inventive concept, this embodiment also provides a method of using the striking device as described above, including: step S1, opening and closing the air intake valve 220 at a preset frequency of industrial control software, so that the piston rod 211 strikes the side wall of the tray 110 at the preset frequency to adjust the position of the chip 100 in the tray 110.

[0049] In some embodiments, the tapping device further includes a controller electrically connected to the air intake valve 220 and the robotic arm; optionally, the industrial control software is built into the controller. Before performing step S1, the method further includes: the robotic arm placing the chip 100 into the tray 110 and sending a chip placement signal to the controller. Step S1 includes: after receiving the chip placement signal, the controller controls the air intake valve 220 to open and close at the preset frequency. Furthermore, the method further includes: in step S2, after a preset time has elapsed, i.e., after the position of the chip 100 has been adjusted, the controller also controls the air intake valve 220 to close, so that the piston rod 211 stops tapping the side wall of the tray 110. Optionally, the preset time is 1 second to 10 seconds; preferably, the preset time is 5 seconds.

[0050] Furthermore, when the robotic arm places the chip 100 into the tray 110, the controller also controls the air intake valve 220 to close.

[0051] In summary, the tapping device and method provided in this embodiment allow gas to be introduced into a cylinder via an air inlet valve, pushing a piston rod within the cylinder to extend and retract along its own axis. This causes the piston rod to tap the side wall of a tray, thereby adjusting the position of the chip within the tray. Compared to existing technologies where the position of misaligned chips is manually adjusted, this embodiment automatically adjusts the chip position through the cooperation of the air inlet valve and the cylinder, effectively improving the efficiency of chip position adjustment and consequently enhancing the efficiency of subsequent testing.

Therefore, the scope of protection of the present invention should be defined by the appended claims.
