Description

Technical Field

[0001] This utility model relates to the field of chip sorting technology, and in particular to a chip testing pressure device and a translational chip sorting machine. Background Technology

[0002] Currently, translational chip sorting machines have a chip testing and pressing device, which includes a lifting drive mechanism and a suction nozzle for picking up chips. The lifting drive mechanism drives the nozzle to move up and down. Specifically, after the nozzle picks up a chip, the lifting drive mechanism lowers the nozzle to the testing height, allowing the testing platform to test the chip. After the test is completed, the lifting drive mechanism then raises the nozzle to the set height, and the nozzle picks up the next chip, repeating this cycle. The height the nozzle rises should be as small as possible to reduce the nozzle's upward stroke and improve its operating efficiency. However, when the nozzle is damaged and needs repair, the limited height results in insufficient space underneath, making repair difficult. Therefore, improvements are needed to address this issue.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] like Figure 1-2 As shown in the figure, one embodiment of this utility model discloses a chip testing pressing device, which includes a suction nozzle 7, a lifting drive mechanism, a first position sensor 5, a second position sensor 4, and a controller. The suction nozzle 7 is used to pick up the chip. The lifting drive mechanism is used to drive the suction nozzle 7 to move up and down.

[0034] The chip testing pressing device of this invention has a first state and a second state. In the first state, the first position sensor 5 is active, and the second position sensor 4 is inactive. The first position sensor 5 generates a first signal when the nozzle 7 rises to a first height. The controller uses this first signal to stop the lifting drive mechanism, so that the nozzle 7 remains at the first height. In the second state, the first position sensor 5 is inactive, and the second position sensor 4 is active. The second position sensor 4 generates a second signal when the nozzle 7 rises to a second height. The controller uses this second signal to stop the lifting drive mechanism, so that the nozzle 7 remains at the second height. The second height is greater than the first height.

[0035] The first state described above can be the working state, and the second state can be the shutdown state or the maintenance state. When the chip testing pressing device is working normally, it is in the first state. At this time, the lifting drive mechanism drives the nozzle 7 to descend to the testing height so that the testing platform can test the chip on the nozzle 7. After the test is completed, when the lifting drive mechanism drives the nozzle 7 to rise to the first height, the first position sensor 5 generates a first signal. The controller controls the lifting drive mechanism to stop running according to the first signal, so that the nozzle 7 stays at the first height. Then the nozzle 7 picks up the next chip, and the above actions are repeated. When the nozzle 7 is damaged and needs repair, the chip testing pressing device is in the second state. At this time, when the lifting drive mechanism drives the nozzle 7 to rise to the second height, the second position sensor 4 generates a second signal. The controller controls the lifting drive mechanism to stop running according to the second signal, so that the nozzle 7 stays at the second height. Since the second height is greater than the first height, there is sufficient maintenance space below the nozzle 7, which is convenient for operators to repair or replace the nozzle 7.

[0036] In some embodiments, the aforementioned first position sensor 5 and second position sensor 4 can both be photoelectric sensors, etc.

[0037] In some implementations, such as Figure 1-2 As shown, the aforementioned lifting drive mechanism may include a first motor 1 to provide power for the lifting of the suction nozzle 7. The controller is used to stop the first motor 1 based on a first signal or a second signal, thereby stopping the lifting drive mechanism. In this example, the controller may be a processor or a PLC logic controller, etc. The technology of controlling the motor to stop based on a signal is existing technology and will not be elaborated here.

[0038] To achieve the function of the aforementioned lifting drive mechanism driving the suction nozzle 7 to rise and fall, in some embodiments, such as... Figure 1-2 As shown, the aforementioned lifting drive mechanism also includes a first screw 2 and a first nut seat 3 sleeved on the first screw 2. The aforementioned suction nozzle 7 is disposed on the first nut seat 3. The first motor 1 is used to drive the first screw 2 to rotate, and the first screw 2 is used to drive the first nut seat 3 to rise and fall, so that the first nut seat 3 drives the suction nozzle 7 to rise and fall, thereby realizing the function of the lifting drive mechanism driving the suction nozzle 7 to rise and fall.

[0039] In some embodiments, the aforementioned first position sensor 5 and second position sensor 4 are both used to detect the height position of the first nut seat 3, so as to indirectly detect the height position of the suction nozzle 7 through the height position of the first nut seat 3.

[0040] In this design, the suction nozzle 7 is typically located below the first nut seat 3, closer to the test platform. If the first position sensor 5 and the second position sensor 4 directly detect the height of the suction nozzle 7, their spatial positions would be even closer to the test platform, limiting their installation options. In the example above, by placing the first position sensor 5 and the second position sensor 4 at a higher position and indirectly detecting the height of the suction nozzle 7 by detecting the height of the first nut seat 3, the installation of the first position sensor 5 and the second position sensor 4 is facilitated.

[0041] In some embodiments, the aforementioned chip testing pressing device further includes a lateral drive mechanism for driving the nozzle 7 to move along a first direction, which is perpendicular to the lifting direction of the nozzle 7.

[0042] In the example above, the horizontal drive mechanism and the lifting drive mechanism work together to drive the nozzle 7 to perform compound movements in the horizontal and vertical directions, so as to facilitate the picking and placing of chips.

[0043] To achieve the aforementioned function of the lateral drive mechanism, in some embodiments, such as Figure 1-2 As shown, the aforementioned transverse drive mechanism includes a support base 6, a second motor, a second screw 8, and a second nut seat 9 sleeved on the second screw 8. The support base 6 is movably mounted on the aforementioned first nut seat 3, and the support base 6 can move relative to the first nut seat 3 in a first direction. The first nut seat 3 may be provided with a transverse guide rail 13, which extends along the first direction. The support base 6 may be provided with a sliding block 14, which is slidably engaged with the transverse guide rail 13, so that the support base 6 can move relative to the first nut seat 3 in the first direction.

[0044] The aforementioned suction nozzle 7 is mounted on the support base 6, which in turn mounts it onto the first nut seat 3. The support base 6 can also be vertically engaged with the second nut seat 9. A second motor drives a second screw 8 to rotate, which in turn drives the second nut seat 9 to move along a first direction. This causes the second nut seat 9 to move the support base 6 along the first direction, allowing the support base 6 to move the suction nozzle 7 together in the first direction. This achieves the function of the lateral drive mechanism driving the suction nozzle 7 to move in the first direction. Furthermore, since the support base 6 can be raised and lowered relative to the second nut seat 9, the movement of the first nut seat 3, which moves the support base 6 and the suction nozzle 7, does not affect the lateral movement of the second nut seat 9, ensuring that the movements of the lateral drive mechanism and the lifting drive mechanism do not interfere with each other.

[0045] To enable the support base 6 to be vertically and easily engaged with the second nut base 9, in some embodiments, such as Figure 2As shown, the aforementioned support base 6 may be provided with a longitudinal slide rail 11, the extension direction of which is consistent with the lifting direction of the support base 6. The second nut base 9 is provided with a slider 10, which can be fixed on the second nut base 9. The slider 10 is slidably engaged with the longitudinal slide rail 11 so as to liftably engage the support base 6 with the second nut base 9.

[0046] In some implementations, the aforementioned suction nozzle 7 can float in the lifting direction to eliminate contact error between the chip and the test platform and improve test accuracy.

[0047] To achieve the effect that the suction nozzle 7 can float in the vertical direction, in some embodiments, such as Figure 1-3 As shown, when the chip testing pressing device further includes a lateral drive mechanism, the lateral drive mechanism is used to drive the nozzle 7 to move along a first direction, which is perpendicular to the lifting direction of the nozzle 7; and the lateral drive mechanism includes a support base 6, a second motor, a second screw 8, and a second nut seat 9 sleeved on the second screw 8. The support base 6 is set on the first nut seat 3, and the nozzle 7 is set on the support base 6, so as to be set on the first nut seat 3 through the support base 6; and the support base 6 can also be lifted and locked onto the second nut seat 9. The second motor is used to drive the second screw 8 to rotate, and the second screw 8 is used to drive the second nut seat 9 to move along the first direction, so that the second nut seat 9 drives the support base 6 to move along the first direction, so that the support base 6 drives the nozzle 7 to move together along the first direction. When the support base 6 is provided with a floating cylinder 12, the nozzle 7 is set on the floating cylinder 12, and the nozzle 7 is set on the support base 6 through the floating cylinder 12, and the nozzle 7 floats in the lifting direction through the floating cylinder 12, thereby realizing the effect that the nozzle 7 can float in the lifting direction.

[0048] This utility model also provides a translational chip sorting machine, which may include the chip testing and pressing device described above. Because the translational chip sorting machine uses the aforementioned chip testing and pressing device, when the suction nozzle 7 is damaged and requires repair, the chip testing and pressing device is in a second state. At this time, when the lifting drive mechanism drives the suction nozzle 7 to rise to a second height, the second position sensor 4 generates a second signal. The controller, based on this second signal, controls the lifting drive mechanism to stop operating, so that the suction nozzle 7 remains at the second height. Since the second height is greater than the first height, there is sufficient maintenance space below the suction nozzle 7, facilitating maintenance or replacement by operators.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
