Abstract

This invention relates to a quick-release assembly for a pressure probe and an electronic component testing device incorporating the assembly. The assembly mainly includes an upper base, an actuator, and a lower base. When the lower base is to be assembled onto the upper base, the actuator drives a movable head to a first position. After the movable head passes through an opening slot in the lower base, the actuator drives the movable head to a second position, whereby the movable head secures the lower base. In other words, the quick-release assembly for the pressure probe of this invention has a simple yet reliable structure. First, the movable head of the actuator, positioned on the upper base, is fitted into the opening slot of the lower base. Then, the actuator drives the movable head in a controlled manner, moving it from the first position to the second position. During this movement, the movable head presses against the opening slot of the lower base, thus securing the upper and lower bases together.

Description

Technical Field

[0001] This invention relates to a quick-release assembly for a pressure test head and an electronic component testing device incorporating the assembly, particularly to a modular pressure test head that can be quickly disassembled and installed, and an electronic component testing device incorporating the modular pressure test head. Background Technology

[0002] Because electronic component testing equipment is expensive, both equipment manufacturers and packaging and testing companies try to reuse the testing equipment as much as possible. This means that by modifying the equipment, it can test different specifications of test objects.

[0003] A common modification method is to replace the test socket module and the crimping module within the same machine architecture, since these two modules directly contact the device under test (DUT). Therefore, with different DUTs, the test socket module, which houses and electrically contacts the DUT, and the crimping module, which presses against the DUT to ensure complete electrical contact between the DUT and the test socket, must be replaced.

[0004] However, with existing technology, pressure testing heads are equipped with numerous circuits and fluid lines, such as temperature sensing circuits, pressure sensing circuits, negative pressure lines for picking up chips, temperature control lines for heating or cooling, etc., and also include dampers for shock absorption and error absorbers for position or angle adjustment, etc.; for relevant background technology, please refer to Taiwan Publication No. I733318, "Pressure Testing Mechanism, Test Equipment and Test Method". Therefore, conventional pressure testing heads are almost always fixed to the machine with bolts, making them impossible to disassemble or install arbitrarily. This is quite inconvenient for machine maintenance, repair, and modification.

[0005] Therefore, a modular design, quick disassembly and installation of a pressure test head, a robust structure, and high reliability, as well as electronic component testing equipment equipped with such a component, are eagerly anticipated by industry and the general public. Summary of the Invention

[0006] The main objective of this invention is to provide a quick-release assembly for a pressure test head and an electronic component testing device equipped with the assembly, so as to enable quick disassembly and quick installation of the pressure test head, presenting it in a modular manner, with a very robust structure and excellent reliability.

[0007] To achieve the above objectives, the present invention provides a quick-release assembly for a pressure probe, which mainly includes an upper base, an actuator, and a lower base. The upper base has a through hole. The actuator includes a movable head, which is disposed on the upper surface of the upper base and passes through the through hole, protruding from the lower surface of the upper base. The lower base includes an opening slot. When the lower base is to be assembled onto the upper base, the actuator drives the movable head to a first position. After the movable head passes through the opening slot of the lower base, the actuator drives the movable head to a second position, and the movable head secures the lower base.

[0008] In other words, the quick-release assembly of the pressure probe of the present invention has a simple yet highly reliable structure. First, the movable head of the actuator on the upper base is fitted into the opening slot of the lower base. Then, the actuator drives the movable head in a controlled manner, moving it from a first position to a second position. During this movement, the movable head presses against the opening slot of the lower base, thus securing the upper and lower bases together. Therefore, the quick-release assembly of the pressure probe of the present invention is not only easy to operate and safe and reliable, but importantly, it allows for a simple and quick connection or disengagement of the upper and lower bases simply through the action of the actuator.

[0009] To achieve the aforementioned objectives, the present invention provides an electronic component testing device, comprising multiple quick-release and reassembly assemblies for pressure testing heads as described above, an upper fixed plate, a lower fixed plate, and a lifting arm; wherein the multiple quick-release and reassembly assemblies are disposed on the lower surface of the lower fixed plate, and the lifting arm is disposed on the upper surface of the upper fixed plate, and the upper fixed plate is coupled to the lower fixed plate. Furthermore, dampers can be respectively disposed between the multiple quick-release and reassembly assemblies and the lower surface of the lower fixed plate to generate buffering and avoid direct impact.

[0010] In addition, at least one quick-release fastener can be provided between the upper and lower fixing plates. This fastener may include a hook and a retaining ring. The hook may be located on the side end face of the upper fixing plate, and the retaining ring may be located on the side end face of the lower fixing plate. However, when the upper fixing plate is coupled to the lower fixing plate, the retaining ring can be tightly fastened to the hook. In other words, this invention allows not only individual crimp connectors to be quickly installed and removed, but also the entire fixing plate with all crimp connectors installed can be quickly installed or removed using quick-release fasteners.

[0017] Before the quick-release assembly of the pressure test head of the present invention and the electronic component testing equipment equipped with the assembly are described in detail in this embodiment, it should be noted that similar components will be represented by the same component symbols in the following description. Furthermore, the accompanying drawings of the present invention are for illustrative purposes only and are not necessarily drawn to scale, and not all details may be shown in the drawings.

[0018] Please also refer to Figure 1 and Figure 2 , Figure 1 This is a perspective view of the entire crimp connector in a preferred embodiment of the electronic component testing equipment of the present invention. Figure 2 This is a system architecture diagram of a preferred embodiment of the electronic component testing equipment of the present invention. As shown in the figure, the electronic component testing equipment of this embodiment mainly includes four sets of quick-release components 1, an upper fixing plate 61, a lower fixing plate 11, a lifting arm 6, four dampers 7, and four quick-release fasteners 8; wherein, the lifting arm 6 is controlled by the control unit C to rise or fall, and the lifting arm 6 can be composed of a motor with a screw (not shown in the figure), a linear motor with a slide rail, a pneumatic cylinder, a hydraulic cylinder, or other equivalent devices.

[0019] Furthermore, the lower part of the lifting arm 6 is connected to the upper fixed plate 61, and the lower part of the upper fixed plate 61 is connected to the lower fixed plate 11 through quick-release fasteners 8. Each quick-release fastener 8 includes a hook 81 and a buckle 82. The hook 81 is disposed on the side end face of the upper fixed plate 61, and the buckle 82 is disposed on the side end face of the lower fixed plate 11. However, when the upper fixed plate 61 is coupled to the lower fixed plate 11, the buckle 82 is tightly fastened to the hook 81. In addition, when the lower fixed plate 11 wants to detach from the upper fixed plate 61, it is only necessary to pull the quick-release fastener 8 to release the buckle 82 from the hook 81, which is extremely quick and convenient.

[0020] In addition, all four quick-release components 1 are located on the lower surface of the lower fixed plate 11, and a damper 7 is provided between each quick-release component 1 and the lower fixed plate 11. The damper mainly serves as a buffer to prevent the lifting arm 6 from directly impacting the test head (not shown in the figure) during the process of lowering to pick up or press against the test piece.

[0021] Please refer to the following: Figures 1 to 4 , Figure 3 This is a perspective view of a preferred embodiment of the quick-release assembly for the pressure probe of the present invention. Figure 4 This is a perspective view showing the upper and lower bases separated in a preferred embodiment of the quick-release assembly of the pressure probe of the present invention. The quick-release assembly 1 of this embodiment is further described below. In this embodiment, each quick-release assembly 1 mainly includes an upper base 2, two actuators 3, and a lower base 4.

[0022] The upper base 2 has through holes 21 on opposite sides. Two actuators 3 are a first pneumatic cylinder C1 and a second pneumatic cylinder C2, respectively. Both cylinders are located on the upper surface of the upper base 2 and each includes a movable head 31, which includes a flange 311 and a neck 312. The neck 312 of the movable head 31 passes through the through holes 21 of the upper base 2, and a portion of the neck 312 and the flange 311 protrude from the lower surface of the upper base 2.

[0023] Furthermore, the upper surface of the lower base 4 includes an opening groove 41, which is an elongated groove with its opening facing the side end of the lower base 4. Additionally, each of the two corresponding sides of the neck 312 of the movable head 31 includes a flat section 313, which refers to a specific section of the periphery of the neck 312 being cut axially. The spacing of these flat sections 313 is equal to the opening width of the elongated groove. The purpose of the flat sections 313 is that when the opening groove 41 is fitted into the neck 312, the spacing formed by the flat sections 313 precisely matches the width of the opening groove 41, thus creating a guiding effect. Even when only one movable head 31 is fitted into the opening groove 41, the lower base 4 will not swing left or right.

[0024] again, Figure 4 The image also shows a long fastener 5, which includes two through holes 51 (see below). Figure 5A The two perforations 51 are respectively fitted into the neck 312 of the movable head 31 of the first pneumatic cylinder C1 and the second pneumatic cylinder C2 and are constrained by the flange 311; preferably, the elongated fastener 5 is directly attached to the upper surface of the flange 311. Accordingly, in this embodiment, by overlapping the elongated fastener 5 between the movable heads 31 of the first pneumatic cylinder C1 and the second pneumatic cylinder C2, when the opening slot 41 of the lower base 4 is fitted into the neck 312, the movable heads 31 at both ends can be smoothly guided into the opening slot 41 in sequence by means of the elongated fastener 5, which can completely avoid the situation where only one movable head 31 slides in while the other movable head 31 comes out of the opening slot 41.

[0025] again, Figure 4The image also shows an elongated fastener 5, which includes two through holes 51. Each of the two through holes 51 is fitted into the neck 312 of the movable head 31 of the first pneumatic cylinder C1 and the second pneumatic cylinder C2 and is constrained by the flange 311. Preferably, the elongated fastener 5 is directly attached to the upper surface of the flange 311. Accordingly, in this embodiment, by overlapping the elongated fastener 5 between the movable heads 31 of the first pneumatic cylinder C1 and the second pneumatic cylinder C2, when the opening slot 41 of the lower base 4 is fitted into the neck 312, the movable heads 31 at both ends can be smoothly guided by the elongated fastener 5 to slide sequentially into the opening slot 41 along the elongated fastener 5, which completely avoids the situation where only one movable head 31 slides in while the other movable head 31 comes out of the opening slot 41.

[0026] Please refer to the following: Figure 4 , Figure 5A and Figure 5B , Figure 5A This is a cross-sectional view of the movable head of the actuator in a first position in a preferred embodiment of the quick-release assembly of the pressure probe of the present invention. Figure 5B This is a cross-sectional view of the movable head of the actuator in a second position in a preferred embodiment of the quick-release assembly of the pressure probe of the present invention.

[0027] The following describes the operation of the quick-assembly / disassembly component 1 in this embodiment; firstly, when the lower base 4 is to be assembled onto the upper base 2, the control unit C controls the actuator 3 to drive the movable head 31 to the first position, such as... Figure 5A As shown, this is the limit position of the downward protrusion of the movable head 31.

[0028] Furthermore, the opening slot 41 of the lower base 4 is first aligned with the movable head 31 of the actuator 3 from the side; then, the lower base 4 slides into the upper base 2 from the side and is positioned directly below it, allowing the opening slot 41 to pass through the neck 312 of the movable head 3 of the actuator 3, while the flange 311 and the elongated fastener 5 are located below the opening slot 41. In addition, in this embodiment, two corresponding diagonal positioning pins 44 are provided on the upper surface of the lower base 4, and two corresponding diagonal positioning holes 23 are provided on the lower surface of the upper base 2; however, after the opening slot 41 of the lower base 4 is fully inserted into the neck 312 of the movable head 3 of the actuator 3, the two positioning pins 44 of the lower base 4 will align with the two positioning holes 23 of the upper base 2.

[0029] Next, the control unit C controls the actuator 3 to drive the movable head 31 to move axially, so that it is in the second position, such as... Figure 5B As shown, this is the limit position where the movable head 31 retracts upward. At this time, the flange 311 of the movable head 31 tightly clamps the two sides of the opening slot 41 of the lower base 4 and the elongated fastener 5, so that the upper base 2 and the lower base 4 are securely connected, thereby completing the assembly operation of the lower base 4.

[0030] On the other hand, when the current base 4 is to be detached from the upper base 2, the control unit C controls the actuator 3 to drive the movable head 31 to the first position, i.e. Figure 5A As shown; at this time, the lower base 4 can be detached from the lower base 4. Simply slide the lower base 4 along the guide of the opening slot 41 and slide the movable head 31 out in the opposite direction.

[0031] It is worth mentioning that, in this embodiment, both the first pneumatic cylinder C1 and the second pneumatic cylinder C2 are equipped with a position sensor 32, please see... Figure 2 The sensor, used to sense whether the movable head 31 is in the first or second position as expected, can be composed of, for example, a proximity switch, a photoelectric switch, or a pressure sensor. However, if the movable head 31 is not in the first or second position, the control unit C immediately determines that the lower base 4 has failed to install or detach, and will issue a warning to notify the on-site operator.

[0032] In addition, please refer to Figure 2 , Figure 5A and Figure 5B In this embodiment, the quick-release assembly 1 of the pressure probe also provides a negative pressure gas channel to facilitate the addition of adsorption and chip placement functions. Further, the upper base 2 includes a negative pressure channel 22, one end of which is coupled to a negative pressure source (not shown in the figure), and the other end opens onto the lower surface of the upper base 2. Additionally, the lower base 4 includes a fluid channel 42, one end of which opens onto the upper surface of the lower base 4, and the other end opens onto the lower surface of the lower base 4, forming a chip placement / removal hole 43.

[0033] Accordingly, when the lower base 4 is assembled on the upper base 2, the negative pressure channel 22 of the upper base 2 will align with the fluid channel 42 of the lower base 4. Therefore, the chip pick-and-place hole 43 will be able to connect to the negative pressure source to form a negative pressure, which can adsorb the device under test. Furthermore, an O-ring 45 is provided at the junction of these two channels to prevent air leakage. Additionally, as... Figure 2 As shown, in this embodiment, a solenoid valve 9 is provided between the negative pressure channel 22 of the upper base 2 and the negative pressure source. It is electrically connected to the control unit C and is used to control whether the negative pressure channel 22 is connected to the negative pressure source or not. It can also be used to control the adsorption or placement of the test piece (not shown in the figure).

[0034] Overall, this embodiment has at least the following unexpected effects:

[0035] Installation and disassembly are quite simple. The pneumatic cylinder can be activated by issuing a control command through the control unit. The operator only needs to guide the lower base along the guide of the slot, fit the slot onto the movable head, or slide the slot out to detach it from the movable head. Moreover, the upper and lower bases are modular and the connection is very stable through the locking of the pneumatic cylinder, which can achieve quick disassembly and quick installation of the pressure probe, with excellent reliability.

[0036] The spacing formed by the flat cut segments of the neck of the movable head exactly matches the width of the opening slot, thus creating a guiding effect. Even if only one movable head is inserted into the opening slot, the lower base will not swing left or right.

[0037] The long fastener overlaps between the movable heads of the first and second pneumatic cylinders. Therefore, when the opening slot of the lower base is fitted into the neck, the movable heads at both ends can be smoothly slid into the opening slot in sequence with the help of the long fastener. This completely avoids the situation where only one movable head slides in while the other movable head comes out of the opening slot.

[0038] The first and second pneumatic cylinders are each equipped with a position sensor; if the position where the movable head stops is not in the first or second position, the control unit will immediately determine that the lower base installation has failed or the lower base has failed to detach, and will issue a warning to notify the on-site operators.

[0039] The upper base has positioning holes at the two diagonally opposite ends of its lower surface, while the lower base has positioning pins at the corresponding diagonally opposite ends of its upper surface. When the lower base is to be assembled onto the upper base, the positioning pins can be aligned with the positioning holes to achieve precise alignment between the upper and lower bases.

[0040] The upper base is provided with a negative pressure channel, and the lower base is provided with a fluid channel. When the lower base is assembled on the upper base, the negative pressure channel of the upper base will be aligned with the fluid channel of the lower base. Therefore, the chip pick-up and drop-off hole can be connected to the negative pressure source to form a negative pressure, which can be used to adsorb the test piece. In addition, an O-ring is provided at the joint of the two channels to prevent air leakage.

[0041] The lower and upper fixing plates can be quickly engaged or disengaged via quick-release buckles. When the upper fixing plate is to be coupled to the lower fixing plate, simply pull the quick-release buckle to lock the buckle into the hook. Similarly, when the lower fixing plate is to be disengaged from the upper fixing plate, simply pull the quick-release buckle to release the buckle from the hook. This is extremely quick and convenient.

[0042] The above embodiments are merely illustrative examples for ease of explanation. The scope of the claims of this invention should be determined by the scope of the claims, and not limited to the above embodiments.
