Description

Technical Field

[0001] The utility model relates to the technical field of chip testing, in particular to a micro thermal capacitor harness control device. Background Art

[0002] Currently, in the field of memory chip testing, whether it is aging test or function and speed test, multiple high temperature and low temperature tests are required. The test chamber of the test machine needs to be temperature calibrated regularly or when new products are introduced. The temperature compensation value is set by temperature calibration to ensure that the temperature of the test chamber can meet the requirements during production.

[0003] The mainstream instrument used for temperature calibration at present is a miniature thermal capacitor with a very long wire, which is used in conjunction with a temperature data acquisition and transmission card and a computer. During temperature calibration, 20 thermal capacitors are often pasted onto the chip used for temperature calibration, and these chips with thermal capacitors are placed at different positions on the test tray to read the temperature data at different positions.

[0004] Due to the large number of micro thermal capacitors, the length of the wires connected to them exceeds 5 meters, while the diameter of the wires themselves is only 0.5 mm. There is currently no good device to control these micro thermal capacitors, which makes the wires tangled together and very messy. Each temperature calibration takes a lot of time to comb the wires. In addition, many wires are severely bent, which makes it impossible for the corresponding micro thermal capacitors to read temperature data.

[0005] Secondly, since the test tray needs to be placed in the test cavity, the wires of the micro thermal capacitors are fixed by high-temperature resistant tape. The lengths of the wires of the micro thermal capacitors are often adjusted differently, some are too long, and some are too short. This causes the short ones to be pulled when placed in the tray, causing the thermal capacitor to separate from the chip to which it is attached, resulting in distortion of the read temperature value. The long ones will result in insufficient wires remaining outside the cavity, causing the connected temperature transmission and acquisition cards to be suspended in mid-air, and all the excess wires need to be attached to the tray to ensure that they do not cause interference.

[0006] Therefore, it is necessary to design a new technical solution. Utility Model Content

[0007] The utility model aims to provide a miniature thermal capacitor harness control device, which solves the problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a miniature thermal capacitor harness control device, comprising a base, a plurality of evenly distributed wheel discs are arranged on the top of the base, a wheel disc fixing device is attached to one side wall of the base, a plurality of evenly distributed limiting holes are opened on the outer wall of the wheel disc fixing device, screws are passed through the limiting holes, the screws and the base are threadedly engaged, the wheel disc fixing device is a plate body, a plurality of evenly distributed limiting pieces are fixed on one side wall of the wheel disc fixing device, two adjacent limiting pieces can limit and press the bottom of the wheel disc, the wheel disc comprises a wheel disc support seat, a limiting block is fixed on one side wall of the wheel disc support seat, a wiring hole is opened on the outer wall of the limiting block, and a wheel disc is fixed on the tail end of the wheel disc support seat The base comprises a mounting groove on the side wall of the wheel base, the limiting piece is clamped in the mounting groove, a first mounting hole is formed on the side wall of the wheel support seat, a disk body is provided on one side of the wheel support seat, a wheel shaft mounting hole is formed on the surface of the disk body, a torsion spring sleeve is fixed in the wheel shaft mounting hole through the wheel shaft, a wheel center hole is formed on the end face of the wheel shaft, a torsion spring is installed in the inner cavity of the torsion spring sleeve, the outer end of the torsion spring sleeve is fixedly connected to the first mounting hole through the wheel shaft connecting piece, an annular groove is formed on the outer peripheral wall of the disk body, a wire groove is formed on one side wall of the disk body, a plurality of evenly distributed wire outlet holes are formed on one side wall of the base, and a plurality of evenly distributed wire inlet holes are formed on the other side wall of the base.

[0009] By adopting the above technical scheme, the capacitor wire is first passed through the wire entry hole, and then the capacitor wire is passed through the wire hole on the limit block, and then the capacitor wire is passed through the first mounting hole and the wheel center hole of the wheel shaft connector, the torsion spring sleeve and the wheel shaft, and then the capacitor wire is passed through the wire groove, and finally the capacitor wire is wound around the annular groove on the disk body, and then the outer end of the capacitor wire is passed through the wire outlet hole, and finally the micro-thermal capacitor probe at the outer end of the capacitor wire after threading is pasted on the surface of the chip used for temperature verification to capture the temperature signal, so that the micro-thermal capacitor wire body wound on the disk body can be easily pulled out. When the disk body is loosened, due to the elastic action of the torsion spring, the disk body rotates in the opposite direction and automatically retracts the excess wire body. In the utility model, each wheel independently controls a micro-thermal capacitor wire body, which eliminates the problem of wire bodies being entangled with each other during use, and the problem that the wire length is difficult to adjust and the micro-thermal capacitor pasted on the surface of the chip used for temperature verification falls off and the temperature data cannot be read due to the inappropriate length of the wire body.

[0010] As a preferred embodiment of the utility model, a limiting groove is provided on one side wall of the roulette base, a roulette controller is arranged in the limiting groove, a guide hole is provided on one side wall of the inner cavity of the limiting groove, a push rod mounting hole is provided on the other side wall of the roulette base, a push rod is inserted into the inner cavity of the push rod mounting hole, the inner end of the push rod is fixedly passed through the roulette controller and inserted into the guide hole, the outer end of the push rod is fixedly connected with a control button, the outer wall of the push rod is sleeved with a spring, and the spring is placed between the roulette base and the control button.

[0011] By adopting the above technical solution, the push rod can generate a certain pulling force on the roulette controller under the action of the spring, so that the roulette controller will be pressed against the bottom of the disc body, thereby limiting the disc body and preventing the disc body from rotating. When the line body needs to be released, the control button is pressed to move the push rod, thereby pushing the roulette controller to one side, thereby releasing the disc body, so that the disc body can retract and release the line body.

[0012] As a preferred embodiment of the utility model, a limiting plate is attached to one side wall of the disk body corresponding to the wire groove, and screw holes are opened on both side walls of the limiting plate. Bolts penetrate the screw holes and are connected to the side wall of the disk body.

[0013] By adopting the above technical solution, the limiting plate can be used to limit the wire body passing through the wire groove to ensure stability.

[0015] By adopting the above technical solution, the wires are independently led out from each wheel and then pass through the air pipe, which effectively realizes the protection of the micro thermal capacitor wire and further eliminates the problem of mutual entanglement of the wires.

[0016] As a preferred implementation of the utility model, the outer wall of the control button is covered with a polyurethane rubber sleeve.

[0017] By adopting the above technical solution, the setting of the polyurethane rubber sleeve can improve the hand feel and avoid scratching the fingers when pressing.

[0018] As a preferred embodiment of the present utility model, a handle is fixed to one end of the outer wall of the wheel fixing device.

[0019] By adopting the above technical solution and the arrangement of the handle, pulling the handle can cause the limiting piece to be separated from the installation groove, thereby allowing the wheel to be quickly disassembled.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] The utility model can automatically retract the pulled-out excess wires by realizing the management of the retraction and release of multiple micro thermal capacitor wire harnesses, and the multiple micro thermal capacitors are independently controlled and managed, thus solving the existing problems of the micro thermal capacitor wires being entangled, twisted, and bent;

[0022] A protective device with high and low temperature resistance is added to the design of the wire itself, so that the wire will not bend or break, while still having the ability to bend. The length of the wire can be used in a quantitative manner and will not be pulled out too long or too short, avoiding problems such as the thermal capacitor falling off. It also avoids the problem of temperature data being unable to be read due to the thermal capacitor falling off during temperature calibration. BRIEF DESCRIPTION OF THE DRAWINGS
