[0002] Ceramic resistors are resistors made of ceramic materials. After they are produced, they need to be tested to reduce the defective rate.

[0003] After the existing columnar ceramic resistors are produced, their thickness specifications and high temperature resistance will be tested. The thickness of the existing ceramic resistors is mostly measured by a tape measure, which often leads to measurement errors due to factors such as reading errors and zero scale misalignment. In addition, the tape measure measurement efficiency is low and is only suitable for the production of a small number of resistors.

[0004] The high temperature resistance measurement of columnar ceramic resistors is generally carried out by placing multiple resistors inside the heating chamber. If the resistors do not burn or smoke within the specified time, it means that the high temperature resistance of the resistors is qualified. This detection method can only be carried out in batches, and there is a detection vacuum period, so the efficiency is not high enough. Therefore, a ceramic resistor detection device is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions 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 only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-4 A ceramic resistance detection device includes a relatively arranged support frame 1, the support frame 1 is provided with two groups, a rotating shaft is rotatably connected between the support frames 1, the rotating shaft is hollow, an electric heating rod is arranged inside the rotating shaft, a ceramic spiral conveying piece 3 is fixedly connected to the surface of the rotating shaft, a driving motor 4 is installed on one side of the support frame 1, the output end of the driving motor 4 is fixedly connected to the rotating shaft, and a plurality of heat-conducting carbon fibers are arranged on the surface of the ceramic spiral conveying piece 3.

[0023] It should be noted that: the driving motor 4 drives the rotating shaft to rotate, and the rotating shaft drives the ceramic spiral conveying blades to rotate, which can realize the conveying function of the columnar ceramic resistor, and at the same time, the ceramic spiral conveying blades can realize the heating function of the columnar ceramic resistor, thereby realizing the high temperature resistance performance detection function of the columnar ceramic resistor, eliminating the vacuum period of the high temperature resistance performance detection, and improving the efficiency of the high temperature resistance performance detection;

[0024] It is worth noting that the heat-conductive carbon fibers can increase the friction between the ceramic spiral conveying sheet 3 and the columnar ceramic resistor, thereby ensuring the stability of the ceramic resistor conveying.

[0025] A screening plate 2 is fixedly connected between the support frames 1 and below the ceramic spiral conveying plate 3. A screening opening 201 is provided at the center of the top of the screening plate 2. A conveying plate 13 symmetrical to the screening opening 201 is fixedly connected to the top of the screening plate 2.

[0026] It should be noted that the conveying plate 13 can support qualified columnar ceramic resistors, and columnar ceramic resistors with a thickness specification smaller than the qualified standard will pass through the spacing between the ceramic spiral conveying plates 3 and fall into the recovery box below through the screening port 201.

[0027] The top of the screening plate 2 is fixedly connected to an L-shaped support plate 6 which is relatively arranged, and a magnet block 14 is fixedly connected to one side of the L-shaped support plate 6, and the clamping plate 9 and the magnet block 14 are magnetically attracted to each other, and a baffle 11 is fixedly connected to one side of the L-shaped support plate 6, and a pressure sensor 12 is installed on one side of the baffle 11 near the bottom end, and a fixed sleeve is fixedly connected to the top of the L-shaped support plate 6, and an electric push rod 5 is installed on the inner side of the fixed sleeve, and a push plate 7 is fixedly connected to the output end of the electric push rod 5, and a guide assembly is arranged above the ceramic spiral conveying sheet 3, and a slide groove is provided at the bottom end of the push plate 7, and a slide block which is relatively arranged is slidably connected in the slide groove, and a clamping spring 10 is fixedly connected between the slide blocks, and a clamping spring 10 is fixedly connected to the bottom end of the slide block, and a clamping plate 9 is fixedly connected to the bottom end of the slide block, and an inclined surface is arranged at the bottom end of the clamping plate 9.

[0028] It should be noted that: a controller is installed on the inner wall of the L-shaped support plate 6, and the controller is electrically connected to the electric push rod 5 and the pressure sensor 12;

[0029] When the ceramic resistor with a thickness larger than the qualified standard moves under the support and conveying action of the ceramic spiral conveyor sheet 3, the conveying height of the ceramic resistor is higher than the qualified ceramic resistor. When the ceramic resistor hits the blocking rod 11, it will squeeze the pressure sensor 12. The pressure sensor 12 will feel the pressure and feedback to the controller. The controller controls the electric push rod 5 to work, so that the push plate 7 drives the clamping plate 9 to move downward, and the push block will push the inclined plate 8 to both sides to open the inclined plate 8. When the inclined surface of the clamping plate 9 contacts the ceramic resistor, the clamping plate 9 will move to both sides and stretch the clamping spring 10 to store energy. When the clamping surface of the clamping plate 9 contacts the ceramic resistor, under the action of the clamping spring 10, the clamping plate 9 realizes the clamping function of the ceramic resistor.

[0030] When the pushing plate 7 drives the clamping plate 9 and the unqualified ceramic resistor to reset, the inclined plate 8 is reset under the action of the torsion spring. At the same time, under the magnetic attraction of the magnet block 14, the clamping plate 9 loses its clamping force on the ceramic resistor, causing the unqualified ceramic resistor to fall onto the inclined plate 8 and, under the guidance of the inclined plate 8, slide into the recycling box prepared in advance.

[0031] It is worth noting that: before the ceramic resistor detection work, a recovery box for recovering ceramic resistors with too large specifications needs to be placed at one end of the inclined plate 8; a recovery box for recovering ceramic resistors with smaller specifications needs to be placed under the screening plate 2; and a recovery box for recovering qualified ceramic resistors needs to be placed near the drive motor 4.

[0032] The top end of the screening plate 2 is fixedly connected with an auxiliary rod arranged opposite thereto. The guide assembly comprises an inclined plate 8 rotatably connected between the auxiliary rod and the L-shaped support plate 6. A torsion spring is arranged at the connection between the inclined plate 8 and the auxiliary rod.

[0033] It should be noted that the height of the auxiliary rod is lower than that of the L-shaped support plate 6 , so that the inclined plate 8 is arranged obliquely, so that unqualified ceramic resistors can slide into the inside of the recycling box.

[0034] The driving motor 4 is of prior art, and its model is JB5274-91. It can realize the function of driving the rotating shaft to rotate, and will not be described in detail here.

[0035] When the utility model is used, the ceramic resistors to be tested are placed one by one between the ceramic spiral conveyor sheets 3, and the ceramic resistors with smaller specifications will pass through the spacing between the ceramic spiral conveyor sheets 3 and fall into the recovery box below through the screening port 201 for recovery;

[0036] The ceramic resistors with qualified thickness will fall on the conveying plate 13 and move under the conveying action of the ceramic spiral conveying sheet 3. During the movement, the heat generated by the electric heating rod is conveyed to the ceramic resistor through the ceramic spiral conveying sheet 3 to realize its heating function, and then realize its high temperature resistance performance detection function, realize the function of simultaneous detection of the thickness specification of the ceramic resistor and the high temperature resistance performance detection, and greatly improve the detection efficiency;

[0037] During the transportation process, ceramic resistors with unqualified high temperature resistance will be burned. The staff can just take away the burned ceramic resistors. Ceramic resistors with qualified thickness and high temperature resistance will be transported to the end of the ceramic spiral conveyor sheet 3 and fall into the inside of the recycling box for recycling;

[0038] The ceramic resistor with a thickness larger than the qualified standard moves under the support and conveying action of the ceramic spiral conveyor sheet 3. The conveying height of the ceramic resistor is higher than that of the qualified ceramic resistor. When the ceramic resistor hits the blocking rod 11, it will squeeze the pressure sensor 12. The pressure sensor 12 will sense the pressure and feedback to the controller. The controller controls the electric push rod 5 to work, so that the push plate 7 drives the clamping plate 9 to move downward, and the push block will push the inclined plate 8 to both sides, so that the inclined plate 8 rotates and opens. When the inclined surface of the clamping plate 9 contacts the ceramic resistor, the clamping plate 9 will move to both sides and stretch the clamping spring 10 to store energy. When the clamping surface of the clamping plate 9 contacts the ceramic resistor, under the action of the clamping spring 10, the clamping plate 9 realizes the clamping function of the ceramic resistor.

[0039] When the electric push rod 5 drives the pushing plate 7 to reset, and then drives the clamping plate 9 and the unqualified ceramic resistor to reset, the inclined plate 8 is reset under the action of the torsion spring. At the same time, under the magnetic attraction of the magnet block 14, the clamping plate 9 loses its clamping force on the ceramic resistor, causing the unqualified ceramic resistor to fall onto the inclined plate 8 and, under the guidance of the inclined plate 8, slide into the recycling box prepared in advance to complete recycling.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
