DETAILED DESCRIPTION
[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0026] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0027] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0028] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] As mentioned in the background technology, the push pins of the traditional chip push-pull force test bench are vertical and horizontal, which can easily cause the push pins to break or bend, affecting the test data. In order to improve the above problems, the present application provides a push-pull force test device, which sets the push pins horizontally, making them less likely to deform and break, thereby improving the accuracy of the test.
[0030] See also Figure 1 , Figure 1 Schematic diagram of a push-pull force testing device 10 provided by an embodiment of the present utility model. The present application provides a push-pull force testing device 10, which includes a mounting platform 100, a testing assembly 300, a loading member 500 and a power unit.
[0031] Among them, the test component 300 and the carrier 500 are arranged on the mounting platform 100 in sequence along the length direction of the mounting platform 100; the carrier 500 is used to place the chip frame base; the test component 300 includes a thrust gauge 310 and a push pin 330, the thrust gauge 310 is arranged on the mounting platform 100, one end of the push pin 330 is connected to the thrust gauge 310, and the other end extends in the direction of approaching the carrier 500; the power unit is arranged on the mounting platform 100 and connected to the thrust gauge 310, and is used to drive the thrust gauge 310 to move closer to or away from the carrier 500.
[0032] Based on the above configuration, when the power unit drives the thrust gauge 310 to approach the object carrier 500, the push pin 330 moves with the thrust gauge 310 until it contacts and pushes away the chip on the chip frame base. During this process, the thrust gauge 310 can record the highest value. Afterwards, the power unit will drive the thrust gauge 310 away from the object carrier 500, reset to the initial position, and wait for the next detection.
[0033] It can be understood that during the above test process, one end of the push pin 330 is connected to the thrust gauge 310, and the other end extends along the length direction of the mounting platform 100, that is, the push pin 330 is arranged horizontally, which avoids deformation or breakage during the process of pushing the chip away, thereby ensuring the accuracy of the numerical value obtained by the thrust gauge 310.
[0034] In order to prevent the chip frame base from popping out during the test, the object carrier 500 is provided with a positioning groove 510 that cooperates with the chip frame base. Based on the above configuration, during operation, the staff only needs to place the chip frame base into the positioning groove 510 without the need for other external fixing devices, thereby simplifying the operation steps. Optionally, the depth of the positioning groove 510 is consistent with the thickness of the chip frame base.
[0035] Furthermore, to achieve the fixation between the object carrier 500 and the mounting platform 100, the push-pull force testing device 10 further includes screws, and the object carrier 500 is fixedly connected to the mounting platform 100 through the screws. Based on this, it is convenient for the staff to replace the object carrier 500 to adapt to different types of chip frame bases.
[0036] like Figure 1 As shown, since the push pin 330 is suspended at one end away from the thrust gauge 310 and is prone to swinging up and down, the push-pull force testing device 10 also includes a limit member 400, which is connected to the mounting platform 100 and is located between the thrust gauge 310 and the object carrier 500, and the limit member 400 is provided with a through hole that cooperates with the push pin 330.
[0037] Based on the above arrangement, on the one hand, the suspended end of the push pin 330 is supported by the limit member 400 and will not shake up and down, thus affecting the accuracy of the test result; on the other hand, the push pin 330 is also guided and constrained by the limit member 400 to ensure that the push pin 330 moves along the length direction of the mounting platform 100.
[0038] In addition, in order to further improve the stability of the test process of the push pin 330, multiple limiters 400 can be set along the length direction of the mounting platform 100, or the limiters 400 can be ensured to have a certain thickness, so as to balance the forces at various locations of the push pin 330. In other embodiments, the limiter 400 can also be a support block with an arc-shaped notch on the top, which can meet the requirements of the push pin 330 to pass through, and will not be repeated here.
[0039] As an optional embodiment, the test assembly 300 further includes a sliding tray 350, and the thrust meter 310 is connected to the power unit through the sliding tray 350 and is slidably connected to the mounting table 100. Figure 1 As shown, one side of the sliding tray 350 is connected to the thrust meter 310, and the other side is connected to the power unit and slidably connected to the mounting platform 100. Based on this, the thrust meter 310 is prevented from directly contacting the mounting platform 100 and being damaged by the friction generated during the reciprocating movement.
[0040] Optionally, the mounting platform 100 is provided with a slide groove 110 that cooperates with the sliding tray 350, and the slide groove 110 extends along the length direction of the mounting platform 100. It should be noted that, on the one hand, the slide groove 110 can position and guide the sliding tray 350 to ensure that it reciprocates along the length direction of the mounting platform 100; on the other hand, the slide groove 110 can also limit the lateral movement of the sliding tray 350 to prevent it from deviating from a predetermined trajectory.
[0041] On this basis, in order to facilitate the connection between the power unit and the sliding tray 350, a mounting groove that matches the power unit is opened on the bottom wall of the slide slot 110. Based on the above configuration, the power unit in the mounting groove is connected to the sliding tray 350, and drives the sliding tray 350 to slide back and forth relative to the bottom wall of the slide slot 110.
[0042] Next, the power unit will be described in detail. To improve the test accuracy, the power unit includes a motor 710, a gearbox 730 and a screw 750, the output shaft of the motor 710 is connected to the input shaft of the gearbox 730, the output shaft of the gearbox 730 is connected to the screw 750, and the end of the screw 750 away from the gearbox 730 is connected to the thrust meter 310.
[0043] It is understandable that the motor 710 can achieve precise speed and torque control by adjusting the current or voltage, and after being driven by the gearbox 730 and the screw 750, the rotary motion is converted into linear motion, so as to drive the test component 300 to move back and forth and improve the test accuracy. Among them, the motor 710 is a DC motor 710 with a rated voltage of 24V. In addition, in other embodiments, the power unit can also be set to a pneumatic cylinder or a hydraulic cylinder to drive the test component 300 to move back and forth during the test process, which will not be repeated here.
[0044] In addition, if Figure 2 and Figure 3 As shown, the push-pull force testing device 10 also includes a control circuit 900 electrically connected to the power unit. In detail, the control circuit 900 includes a normally closed inching type travel switch K1 and a circuit switching module 910, and the normally closed inching type travel switch K1 is connected in series with the circuit switching module 910, and the start switch K6 is connected in parallel to both ends of the normally closed inching type travel switch K1.
[0045] The circuit switching module 910 includes a capacitor C1, a relay J1, a normally open inching type travel switch K2, a first switch K3, a second switch K4, a third switch K5, a first contact Y1, a second contact Y2, a third contact Y3, a fourth contact Y4 and a motor 710.
[0046] like Figure 3As shown, when the normally open inching type travel switch K2 is closed, the relay J1 attracts the first switch K3 and connects it to the second contact Y2, the second switch K4 is connected to the third contact Y3, and the third switch K5 is connected to the fourth contact Y4. That is, one end of the motor 710 is connected in series with the normally closed inching type travel switch K1 through the third switch K5, and the other end is connected to the circuit through the second switch K4, and the motor 710 reverses.
[0047] like Figure 2 As shown, when the normally open inching type travel switch K2 is turned on, the first switch K3 is connected to the first contact Y1, the second switch K4 is connected to the second contact Y2, and the third switch K5 is connected to the third contact Y3, that is, one end of the motor 710 is connected in series with the normally closed inching type travel switch K1 through the second switch K4, and the other end is connected to the circuit through the second switch K5, and the motor 710 rotates forward.
[0048] In addition, it can be understood that the normally closed inching type travel switch K1 and the normally open inching type travel switch K2 are both arranged on the mounting platform 100, and the normally closed inching type travel switch K1 is located at the starting position, and the normally open inching type travel switch K2 is located at the end position.
[0049] Taking this embodiment as an example, the working principle and working process of the push-pull force testing device 10 provided in this application are as follows:
[0050] After the circuit is powered on, the start switch K6 is pressed, and the test component 300 carried by the power unit moves toward the normally open momentary travel switch K2. When the push pin 330 of the test component 300 pushes the chip on the chip frame base, the normally open momentary travel switch K2 is closed, and the motor 710 in the power unit reverses. The power unit will drive the thrust component away from the carrier 500, reset to the initial position, and touch the normally closed momentary travel switch K1. The circuit is powered off and the motor 710 stops moving.
[0051] In summary, the present application provides a push-pull force testing device 10, which includes a mounting platform 100, a test assembly 300, a carrier 500, and a power unit. The test assembly 300 and the carrier 500 are sequentially arranged on the mounting platform 100 along the length direction of the mounting platform 100; the carrier 500 is used to place the chip frame base; the test assembly 300 includes a thrust gauge 310 and a push pin 330, the thrust gauge 310 is arranged on the mounting platform 100, one end of the push pin 330 is connected to the thrust gauge 310, and the other end extends in a direction close to the carrier 500; the power unit is arranged on the mounting platform 100 and connected to the thrust gauge 310, and is used to drive the thrust gauge 310 to move closer to or away from the carrier 500. Based on the above arrangement, one end of the push pin 330 is connected to the thrust gauge 310, and the other end extends along the length direction of the mounting platform 100, that is, the push pin 330 is arranged horizontally, thereby avoiding deformation or breakage thereof in the process of pushing the chip away, and ensuring the accuracy of the numerical value obtained by the thrust gauge 310.
[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
