Description

Technical Field

[0001] The utility model relates to the field of detection technology, and more specifically, to a modulator. Background Art

[0002] After semiconductors are produced, they need to be inspected by light. People control the range and clarity of the light shining on the semiconductor by adjusting the modulator, so that they can detect the conditions under which light shines on the semiconductor in different situations.

[0003] There is a channel of variable size inside the modulator for light to pass through. During detection, the modulator needs to be controlled to make the light shining on the semiconductor become clearer and clearer. Therefore, in the initial state, the channel inside the modulator for light to pass through is larger, and the modulator is in a compressed state. When people need to control the clarity of the light, they need to reduce the compression degree of the modulator, so that the light passing through the modulator and shining on the semiconductor is clearer. Since the modulator is in a compressed state for a long time in the initial state, the structural strength of the modulator decreases with the increase of usage time, thereby affecting the service life of the modulator. Therefore, a structure is set to solve the problem of the modulator's service life being affected by being in a compressed state for a long time. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a modulator, which can improve the overall light transmission quality of the modulator through structural settings.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: the modulator includes an annular shell, which has elastic deformation performance along its height direction, and a plurality of light-transmitting rods are slidably connected in the shell, and a light-transmitting channel is formed between adjacent light-transmitting rods, and the distance between the shells in the height direction is proportional to the cross-sectional area of ​​the light-transmitting channel.

[0006] The utility model is further configured as follows: the light-transmitting rod slides along the width direction of the shell, and the length of the light-transmitting rod is greater than the radius of the shell.

[0007] The utility model is further configured as follows: a plurality of support plates with arc-shaped cross-sections are fixedly connected to the side walls of the shell in the width direction, the openings of the support plates face the center of the shell, and the centers of adjacent support plates coincide.

[0008] The utility model is further configured as follows: a plurality of receiving blocks are fixedly connected to the side walls of the shell in the width direction, the length of the receiving blocks is equal to the thickness of the shell, and the support plate is fixedly connected to the outer peripheral wall of the receiving blocks.

[0009] The utility model is further configured as follows: one end of the support plate is fixedly connected to the receiving block, the cross-sectional area of ​​the receiving block is larger than the cross-sectional area of ​​the light-transmitting rod, the other end of the support plate is fixedly connected to the light-transmitting rod, and the distance between one end of the support plate away from the receiving block and the adjacent receiving blocks is less than the diameter of the shell.

[0010] The utility model is further configured as follows: the supporting force of the receiving block on the supporting plate is greater than the gravity of the supporting plate, and the supporting force of the supporting plate on the light-transmitting rod is greater than the gravity of the light-transmitting rod.

[0011] The utility model is further configured as follows: the shell is made of elastic alloy.

[0012] To sum up, the utility model has the following beneficial effects: when the modulator is in use, people will apply pressure to it, causing the shell to deform along its height direction, causing the receiving blocks to move away from each other along the width direction of the shell. As the receiving blocks move, the light-transmitting rods move toward each other along the width direction, thereby reducing the cross-sectional area of ​​the light-transmitting channel, making the light passing through the modulator and irradiating the semiconductor clearer.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] The modulator, such as Figure 1 and Figure 2 As shown, it includes an annular shell 1, and the hollow shell 1 inside provides activity space for the activities of various components, reducing the thickness of the modulator when in use, and the shell 1 has elastic deformation performance along its height direction. The shell 1 is made of elastic alloy. The shell 1 is made of stainless steel, so that the shell 1 has elasticity while also taking into account good structural strength, thereby extending the service life of the structure. A plurality of light-transmitting rods 2 are slidably connected in the shell 1, and light-transmitting channels are formed between adjacent light-transmitting rods 2. The distance between the shells 1 in the height direction is proportional to the cross-sectional area of ​​the light-transmitting channels. When it is necessary to make the light irradiated on the semiconductor through the modulator clearer, people apply pressure to the outer peripheral wall of the shell 1 to deform it in the height direction. The deformation of the shell 1 will drive the two groups of light-transmitting rods 2 to move in a direction close to each other, thereby reducing the cross-sectional area of ​​the light-transmitting channel, so that the light irradiated on the semiconductor is clearer.

[0018] like Figure 1 and Figure 2 As shown, the light-transmitting rods 2 slide along the width direction of the shell 1, the length of the light-transmitting rods 2 is greater than the radius of the shell 1, and adjacent light-transmitting rods 2 are on the same horizontal plane. By controlling the length of the light-transmitting rods 2, a light-transmitting channel is formed on the side where adjacent light-transmitting rods 2 are close to each other, thereby ensuring the stability of the structure when in use.

[0019] like Figure 1 and Figure 2 As shown, a plurality of support plates 3 with an arc-shaped cross-section are fixedly connected to the side walls of the shell 1 in the width direction. By setting the cross-sectional shape of the support plates 3, the support plates 3 can better adapt to the deformation of the shell 1, thereby reducing the pressure exerted on the support plates 3 on the side walls of the shell 1 and the damage to the support plates 3 caused by the deformation of the shell 1 in the height direction. The openings of the support plates 3 face the center of the shell 1, the centers of adjacent support plates 3 coincide, and the adjacent support plates 3 are symmetrically arranged along the axis of the shell 1, thereby ensuring the stability of the structure during use.

[0020] like Figure 1 and Figure 2 As shown, a plurality of receiving blocks 4 are integrally formed on the side wall in the width direction of the shell 1, and the length of the receiving blocks 4 is equal to the thickness of the shell 1. The support plate 3 is fixedly connected to the outer peripheral wall of the receiving blocks 4. The setting of the receiving blocks 4 provides a supporting effect for the fixation of the support plate 3. By setting the length of the receiving blocks 4, the receiving blocks 4 can better adapt to the shell 1, thereby ensuring the structural strength of the shell 1 when in use and strengthening the stable fixation of the support plate 3.

[0021] like Figure 1 and Figure 2 As shown, one end of the support plate 3 is screwed on the receiving block 4, and the cross-sectional area of ​​the receiving block 4 is larger than the cross-sectional area of ​​the light-transmitting rod 2. The supporting effect of the receiving block 4 on the light-transmitting rod 2 is strengthened by increasing the contact area between the receiving block 4 and the light-transmitting rod 2. The other end of the support plate 3 is fixed to the light-transmitting rod 2 by screws. The distance between the end of the support plate 3 away from the receiving block 4 and the adjacent receiving block 4 is less than the diameter of the shell 1. By setting the position of the end of the support plate 3 away from the receiving block 4, the two groups of light-transmitting rods 2 can be symmetrically arranged along the central axis of the height direction of the shell 1, so that the light-transmitting channel formed by the two groups of light-transmitting rods 2 is located at the inner center of the shell 1.

[0022] like Figure 1 and Figure 2As shown, the supporting force of the receiving block 4 on the supporting plate 3 is greater than the gravity of the supporting plate 3, so that the supporting plate 3 can be stably fixed on the receiving block 4 under the action of the screws, reducing the rotation of the end of the supporting plate 3 away from the receiving block 4 toward the ground under the action of its own gravity. The supporting force of the supporting plate 3 on the light-transmitting rod 2 is greater than the gravity of the light-transmitting rod 2. Through the setting of the screws, the light-transmitting rod 2 can be stably fixed on the receiving block 4 and always perpendicular to the ground, reducing the rotation of the light-transmitting rod 2 along the fixing point with the support plate 3 under the action of its own gravity, thereby ensuring the stability of the structure when the modulator is in use.

[0023] Working principle: When the modulator is needed, the modulator is placed in front of the semiconductor to be detected so that the center of the modulator coincides with the center line of the semiconductor. In the initial state, the cross-sectional area of ​​the light-transmitting channel in the shell 1 is large. At this time, the range of light irradiated on the semiconductor through the light-transmitting channel is large but the clarity is poor. When the light irradiated on the semiconductor needs to be clearer, the operator applies pressure to the outer wall of the shell 1 to deform the shell 1 in the height direction. At this time, the two groups of receiving blocks 4 will move away from each other. The movement of the receiving blocks 4 will drive the support plate 3 fixed on its outer wall to slide together. At this time, the light-transmitting rod 2 fixedly connected to the support plate 3 will move towards each other under the drive of the support plate 3, thereby reducing the cross-sectional area of ​​the light-transmitting channel, making the light irradiated on the semiconductor through the light-transmitting channel clearer.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
