Technical Field

[0001] The invention relates to the field of electronic component production, and more specifically to a high-efficiency ceramic chip short-circuit test tool. Background Art

[0002] Flying probe test is the latest solution to some major problems in electrical testing. It replaces the needle bed with a probe and uses multiple motor-driven, fast-moving electrical probes to contact the pins of the device and perform electrical measurements. When the flying probe contacts the pins on the circuit board, it determines whether the electronic component is normal by judging whether the circuit is connected. However, this equipment is expensive, large in size, and occupies a large area, which increases the equipment cost of the enterprise. Therefore, it is very important to propose a low-cost, high-efficiency detection device.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0037] Embodiment 1

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1 to 14As shown, a high-efficiency ceramic chip short-circuit test tooling comprises a workbench 1, a loading assembly 2 is arranged on one side of the workbench 1, the loading assembly 2 comprises a loading conveyor belt 21 obliquely arranged on the workbench 1, a receiving groove 3 is opened on one side of the loading conveyor belt 21, a buffer assembly 4 is arranged in the receiving groove 3, a unloading conveyor belt 5 is arranged on one side of the receiving groove 3, a detection assembly 6 and a hydraulic assembly 7 driven by the detection assembly 6 are arranged above the receiving groove 3, the hydraulic assembly 7 comprises a hydraulic cylinder 71, and an adsorption assembly 8 is connected to the hydraulic cylinder 71, the loading assembly 2 is used for conveying the ceramic chip 9 to the receiving groove 3 through the loading conveyor belt 21, the buffer assembly 4 is used for buffering the ceramic chip 9 when the detection assembly 6 detects the ceramic chip 9, and the hydraulic assembly 7 is used for making the hydraulic oil in the hydraulic cylinder 71 drive the adsorption assembly 8 to adsorb the ceramic chip 9 to the unloading conveyor belt 5 for unloading when the detection assembly 6 completes the detection and rises.

[0040] It is worth mentioning that Figure 1 and Figure 6 As shown, the loading assembly 2 also includes a loading box 22 fixedly arranged above the loading conveyor belt 21 and a loading port 23 opened below the loading box 22. The distance between the loading port 23 and the loading conveyor belt 21 is consistent with the thickness of a single ceramic tile 9. When in use, the ceramic tile 9 falls onto the loading conveyor belt 21 through the loading port 23 and only one ceramic tile 9 falls at a time to prevent stacking.

[0041] In addition, if Figures 6 to 9 As shown, the buffer assembly 4 includes a fixed cylinder 41 fixedly arranged in the receiving groove 3, a sliding cylinder 42 slidably arranged in the fixed cylinder 41, a buffer plate 43 fixedly arranged on the sliding cylinder 42, a through hole 44 opened on the buffer plate 43, and a plurality of air holes 45 opened on the buffer plate 43. A spring is connected between the sliding cylinder 42 and the fixed cylinder 41, wherein a negative pressure device is connected to the buffer plate 43, so that suction is generated at the air hole 45 and the suction force is smaller than the conveying force of the feeding conveyor belt 21. When in use, when the ceramic piece 9 is conveyed to one end of the feeding conveyor belt 21, the ceramic piece 9 is slowly pushed into the receiving groove 3 and falls on the buffer plate 43. The inclined air holes 45 guide, buffer and adsorb the ceramic piece 9, so that the ceramic piece 9 completely falls into the receiving groove 3 under the conveying force of the inclined feeding conveyor belt 21 and the suction force of the air holes 45, and after the ceramic piece 9 falls into the receiving groove 3, the upper surface of the ceramic piece 9 is flush with the plane of the workbench 1.

[0042] It should be further explained that if Figure 8 and Fig. 9As shown, the detection assembly 6 includes a motor 61 fixedly arranged on the workbench 1, a screw rod 62 fixedly arranged on the output shaft of the motor 61, a nut 63 slidably arranged on the screw rod 62, and a detection plate 64 fixedly arranged on the nut 63, and the detection plate 64 and the accommodating groove 3 are both provided with a contact point 65, and the through-port 44 cooperates with the contact point 65 in the accommodating groove 3, wherein the motor 61 is a forward and reverse motor, which can drive the screw rod 62 to rotate forward and reverse, wherein, when the ceramic piece 9 falls into the accommodating groove 3, the conduction point 11 on the ceramic piece 9 is located in the through-port 44, and the contact point 65 in the accommodating groove 3 is located in the through-port 44, and at this time, the conduction point 11 and the contact point 65 are not Contact. When in use, the motor 61 drives the screw rod 62 to rotate, driving the detection plate 64 and the contact point 65 to descend until the contact point 65 contacts the conduction point 11 on the upper surface of the ceramic piece 9, and then continues to descend while driving the ceramic piece 9, the buffer plate 43, and the sliding cylinder 42 to descend until the conduction point 11 on the lower surface of the ceramic piece 9 contacts the contact point 65 in the accommodating groove 3 in the through opening 44. At this time, the conduction points 11 on the upper and lower sides are in contact with the contact points 65 on both sides, thereby completing the detection. When the detection is completed, the motor 61 reverses, driving the detection plate 64 to rise and separate from the ceramic piece 9, and the buffer plate 43 drives the ceramic piece 9 to reset under the action of the spring.

[0043] It should be emphasized that if Figure 1 As shown, the hydraulic assembly 7 also includes a piston 72 slidably arranged in a hydraulic cylinder 71, and a piston rod 73 fixedly arranged on the piston 72. The hydraulic cylinder 71 is fixedly arranged on the workbench 1. A spring is connected between the piston 72 and the hydraulic cylinder 71. Hydraulic oil is arranged in the hydraulic cylinder 71. When in use, when the detection plate 64 completes the detection and rises, it pushes the piston rod 73 and the piston 72, and the piston 72 slides in the hydraulic cylinder 71, pushing the hydraulic oil to drive the adsorption assembly to slide, thereby playing a linkage role.

[0044] It is worth mentioning that Figures 10 to 14As shown, the adsorption assembly 8 includes a slide 81 provided on the workbench 1, an extension plate 82 slidably arranged on the slide 81, a base 83 fixedly arranged on the extension plate 82, a through groove 84 provided on the base 83, a pull rod 85 slidably arranged in the through groove 84, an adsorption plate 86 rotatably arranged on the base 83, a cylinder 87 fixedly arranged on the base 83, a negative pressure pipe 88 fixedly arranged on the base 83, and a connecting pipe 89 fixedly connected between the slide 81 and the hydraulic cylinder 71. The adsorption plate 86 and the pull rod 85 are hingedly connected by a hinge rod 90, and the negative pressure pipe 88, the base 83, and the adsorption plate 86 are connected. The output shaft of the cylinder 87 is fixedly connected to the pull rod 85, and a spring is connected between the extension plate 82 and the slide groove 81, wherein hydraulic oil is arranged in the connecting pipe 89, the initial state of the adsorption plate 86 is located at the accommodating groove 3 and the cylinder 87 pulls the pull rod 85 to make the adsorption plate 86 face the direction of the detection plate 64, and the negative pressure device is connected to the negative pressure tube 88, so that the adsorption plate 86 generates suction and the suction of the adsorption plate 86 is greater than the suction of the air hole 45. When in use, when the detection plate 64 rises to a certain height, the cylinder 87 pushes the pull rod 85, so that the adsorption plate 86 rotates downward 90° under the action of the hinge rod 90 until it contacts the ceramic piece 9, and under the action of the negative pressure tube 88 The ceramic piece 9 is adsorbed by the bottom. At this time, the detection plate 64 contacts the piston rod 73, pushing the piston rod 73 and the piston 72 to slide. The piston 72 pushes the hydraulic oil to be injected into the chute 81 through the connecting pipe 89, thereby pushing the extension plate 82, the base 83, the adsorption plate 86 and the ceramic piece 9 to slide toward the lower material conveyor belt 5. Then the negative pressure device is closed, the adsorption plate 86 has no suction, and the ceramic piece 9 automatically falls on the conveyor belt for the next process. The cylinder 87 pulls the pull rod 85 again to rotate the adsorption plate 86 upward by 90°. At the same time, the detection plate 64 stops rising and the undetected ceramic piece 9 on the feeding conveyor belt 21 is transported to one end of the transmission belt for feeding. When the ceramic chip 9 falls into the receiving groove 3, the detection plate 64 descends to prepare for detection and at the same time breaks contact with the piston rod 73. The piston rod 73 drives the piston 72 to reset under the action of the spring, and the hydraulic oil is re-drawn into the hydraulic cylinder 71. The spring drives the adsorption plate 86 to reset. Since the adsorption plate 86 is in a vertical state, it will not interfere with the descent and detection of the detection plate 64 during and after the reset. When the detection is completed, the adsorption plate 86 repeats the above-mentioned action of adsorbing and moving the ceramic chip 9, which greatly improves the detection efficiency of the ceramic chip 9 and achieves the effect of continuous detection. At the same time, compared with large-scale detection equipment, this tooling saves the equipment cost of the enterprise.

[0045] Further, such as Figure 7 and Fig. 9 As shown, the direction of the air hole 45 is opposite to the conveying direction of the loading conveyor belt 21. The opposite direction setting can guide, buffer and adsorb the ceramic piece 9 to prevent the ceramic piece 9 from falling or deflecting when it falls into the receiving groove 3.

[0046] In addition, if Figure 1 As shown, a guide plate 10 is provided on the loading conveyor belt 21, and the guide plate 10 is used to limit and guide the ceramic piece 9.

[0047] like Fig.14 As shown, the upper and lower surfaces of the ceramic chip 9 are provided with conduction points 11, and a signal light 12 is provided on the workbench 1. The conduction point 11 cooperates with the through opening 44, and the conduction point 11, the contact point 65 and the signal light 12 are electrically connected. When the ceramic chip 9 is short-circuited, the signal light 12 lights up, and when the ceramic chip 9 is not short-circuited, the signal light 12 does not light up, thereby completing the short-circuit detection of the ceramic chip 9.

[0048] Embodiment 2

[0049] like Figure 1 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that a rubber pad is provided on the piston rod 73.

[0050] Here, in this embodiment, a rubber pad is provided on the piston rod 73 to prevent severe wear and extend its service life.

[0051] Working process

[0052] The ceramic piece 9 falls onto the feeding conveyor belt 21 through the feeding port 23, and is slowly pushed into the containing groove 3 and falls on the buffer plate 43. Then, the motor 61 drives the screw rod 62 to rotate, driving the detection plate 64 and the contact point 65 to descend until the contact point 65 contacts the conduction point 11 on the upper surface of the ceramic piece 9. Then, the ceramic piece 9, the buffer plate 43, and the sliding cylinder 42 are driven to descend during the process of continuing to descend until the conduction point 11 on the lower surface of the ceramic piece 9 contacts the contact point 65 in the containing groove 3 in the through opening 44. At this time, the conduction points 11 on both the upper and lower sides are in contact with the two The contact point 65 on the side contacts with each other, thereby completing the detection. When the detection is completed, the motor 61 reverses, driving the detection plate 64 to rise and separate from the ceramic piece 9. The buffer plate 43 drives the ceramic piece 9 to reset under the action of the spring. When the detection plate 64 rises to a certain height, the cylinder 87 pushes the pull rod 85, so that the adsorption plate 86 rotates downward 90° under the action of the hinge rod 90 until it contacts the ceramic piece 9, and adsorbs the ceramic piece 9 under the action of the negative pressure tube 88. At this time, the detection plate 64 contacts the piston rod 73, pushing the piston rod 73 and the piston 72 to slide, and the piston 72 pushes the hydraulic oil to be injected into the chute 81 through the connecting pipe 89, thereby pushing the extension plate 82, the base 83, the suction plate 86 and the ceramic piece 9 to slide to the lower material conveyor belt 5 until it is above the lower material conveyor belt 5. Then the negative pressure device is closed, the suction plate 86 has no suction, and the ceramic piece 9 automatically falls on the conveyor belt for the next process. The cylinder 87 pulls the pull rod 85 again to rotate the suction plate 86 upward by 90°. At the same time, the detection plate 64 stops rising and the undetected ceramic piece 9 on the feeding conveyor belt 21 is transported to one end of the transmission belt for feeding. When the ceramic piece 9 falls After being in the accommodating groove 3, the detection plate 64 descends to prepare for detection and at the same time breaks contact with the piston rod 73. The piston rod 73 drives the piston 72 to reset under the action of the spring, and the hydraulic oil is re-drawn into the hydraulic cylinder 71. The spring drives the adsorption plate 86 to reset. Since the adsorption plate 86 is in a vertical state, it will not interfere with the descent and detection of the detection plate 64 during and after the resetting process. When the detection is completed, the adsorption plate 86 repeats the above-mentioned action of adsorbing and moving the ceramic piece 9, which greatly improves the detection efficiency of the ceramic piece 9 and saves the equipment cost of the enterprise.
