Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular, to a signal detection device. In addition, the utility model also relates to a medicine bottle detection device including the above signal detection device, and a pharmaceutical production line including the above medicine bottle detection device. Background Art

[0002] Various non-contact switches are needed in the field of detection device technology. Among them, the proximity switch is a position switch that can be operated without direct mechanical contact with the moving parts. When the moving parts contact the sensing area of ​​the switch, the switch can quickly send an electrical signal without contact. It is an ideal electronic switch sensor with a wide range of industrial applications.

[0003] Based on this characteristic of the proximity switch, it can be used to make a detection device that needs to transmit signals frequently. For example, the Chinese patent with patent number CN 219636561 U discloses a film counting device, including a rotating shaft, a non-contact switch, and a counter; the rotating shaft rotates to roll up the film, and the first rotating wheel on the rotating shaft rotates synchronously, and drives the second rotating wheel to rotate through the transmission belt, so that the protrusion set on the second rotating wheel rotates. When rotating, the protrusion can enter or leave the sensing area of ​​the non-contact switch; when the protrusion rotates to enter the sensing area of ​​the non-contact switch, the non-contact switch can sense and output a signal to the counter, and the counter counts. Its film counting device counts in a non-contact form, avoiding the problem of inaccurate counting caused by cam wear and poor contact of the relay.

[0004] However, the above technical solution only realizes a single type of signal by rotating the wheel one circle, and transmits simple information. The number of signals sent by the non-contact switch in the same cycle is equal, and it is impossible to cooperate with the rotating part to transmit multiple signals, which is not convenient for expanding the function of the signal detection device.

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0033] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a signal detection device provided by the utility model.

[0034] A signal detection device, comprising a rotary component 8 and a non-contact switch component arranged above the rotary component 8;

[0035] The non-contact switch assembly includes a plurality of non-contact switches;

[0036] The rotating assembly 8 includes a rotating member, on which is disposed at least one rotating block, which is used to cyclically approach the non-contact switch during rotation and trigger the non-contact switch to transmit a signal, and on which is disposed at least one avoidance groove, which is used to avoid one of the non-contact switches during rotation of the rotating block.

[0037] The utility model arranges at least one rotating block on the rotating member, at least one avoidance groove is provided on the rotating block, and non-contact switches are arranged on the rotating plane of the rotating block, so that when the rotating member drives the rotating block to rotate, the non-contact switch will not be triggered when the avoidance groove of the rotating block approaches the non-contact switch, while the other parts of the rotating block are closer to the non-contact switch than the avoidance groove, so the non-contact switch can be triggered. In this way, by setting different numbers of rotating blocks and cooperating with avoidance grooves at different positions on the rotating block, different non-contact switches can be triggered during the process of the rotating member rotating one circle, thereby transmitting different types and quantities of signals to meet more different signal transmission function needs.

[0038] Preferably, please refer to Figure 1 , 3 As shown, the rotating member also includes a hollow cylinder, the outer wall of which is provided with at least one rotating block, and the outer wall of which is fixedly sleeved with a transmission gear 7, which is used to cooperate with the driving gear of the driving mechanism, and the driving mechanism includes a motor, and the driving gear is arranged on the output shaft of the motor.

[0039] It can be understood that the rotating block is installed through the hollow cylinder, and the rotating cylinder is driven to rotate by the driving mechanism, thereby realizing the rotation of the rotating block, which can achieve compact assembly. Specifically, the driving mechanism can be arranged at the bottom of the rotating block to reduce interference with the installation space of the non-contact switch assembly.

[0040] Preferably, please refer to Figure 1 , 2 As shown in FIGS. 3 and 4 , the avoidance groove on the rotating block is configured as an arc groove structure coaxially arranged relative to the hollow cylinder. When a plurality of arc grooves are provided on the rotating block, the plurality of arc grooves are arranged radially along the hollow cylinder.

[0041] It is understandable that the avoidance grooves at different positions on the same rotary block can correspond to different non-contact switches to achieve the control of whether different non-contact switches are triggered or not.

[0042] Preferably, please refer to Figure 1 , 2 As shown in Figures 3 and 4, a plurality of rotating blocks are provided on the outer wall of the hollow cylinder at intervals along the circumferential direction, and the avoidance grooves on different rotating blocks have different distances relative to the center line of the hollow cylinder.

[0043] It is understandable that the avoidance grooves at different positions on different rotating blocks can correspond to different triggering states of the same non-contact switch when it contacts different rotating blocks, so that the triggering of different non-contact switches can be controlled through the avoidance grooves during the rotating block's one rotation.

[0044] Taking two rotating blocks and one avoidance groove on each rotating block as an example, this preferred embodiment can be applied to light inspection equipment:

[0045] Please refer to Figure 1 , 2 As shown in Figures 3 and 4, a first avoidance groove 9 is provided on the first rotating block, and a second avoidance groove 10 is provided on the second rotating block. The first avoidance groove 9 is closer to the center line of the hollow cylinder, wherein the non-contact switch assembly includes a first proximity switch 1, a second proximity switch 2, a third proximity switch 5 and a fourth proximity switch 6 arranged in an array, wherein the first proximity switch 1, the second proximity switch 2 and the third proximity switch 5 and the fourth proximity switch 6 are distributed on both sides of the hollow cylinder of the rotating member.

[0046] The rotating part is set up to rotate clockwise. Figure 3 In the state, the four proximity switches will not pass through the avoidance groove, so the four proximity switches will be triggered;

[0047] The rotating part continues to rotate. Figure 4In the state of, only the second proximity switch 2 will not pass through the avoidance groove, and the other three proximity switches pass through the avoidance groove or are outside the first rotating block, so only the second proximity switch 2 will be triggered. (The area of ​​the first rotating block in the figure is also smaller than that of the second rotating block, so that the fourth proximity switch 6 can be not triggered by the first rotating block).

[0048] Therefore, one rotation of the rotating part can realize the trigger transmission of multiple signals of different numbers, and changing the position of the avoidance groove or the size of the rotating block can also realize more arrangements of signal transmission.

[0049] The specific effects of this preferred embodiment of the utility model applied to the light inspection machine are:

[0050] The first proximity switch 1 is set as a work position signal, that is, to realize the counting function;

[0051] The second proximity switch 2 is set as the synchronization signal of the detection camera, because the detection camera reciprocates for tracking detection, and tracks and detects 2 bottles at a time. The tracking system tracks two bottles once, that is, 2 bottles are counted as 1 signal, so the second proximity switch 2 needs to be triggered twice;

[0052] The third proximity switch 5 is set as a foreign body detection trigger signal. Since the camera tracks the bottle and rotates synchronously for shooting and detection, the detection camera tracking system needs to track and detect the bottle and can return quickly. The tracking system has an acceleration and deceleration process. When the tracking system and the bottle are synchronously relatively still, a signal is transmitted to the camera to start detection. Two bottles are detected at one time, that is, two bottles are counted as one signal;

[0053] The fourth proximity switch 6 is set as a capping detection trigger signal. When detecting foreign objects, the bottle base is supporting the bottom of the bottle and the pressure head is pressing the bottle head for detection. When the oral liquid is detecting the capping, the pressure head blocks the bottle head and cannot be detected. Therefore, the bottle feed dial wheel is used to detect the capping. It is necessary to add a signal to detect two bottles at a time, that is, 2 bottles are counted as 1 signal.

[0054] Therefore, the technical solution of the present application can meet the requirement that each proximity switch transmits different numbers of signals within a cycle. Of course, the present utility model can also be extended to a wider range of signal transmission control technology fields.

A switch bracket 3 is arranged on the fixed shaft 4, and the switch bracket 3 is used to fix the non-contact switch assembly.

[0056] It can be understood that the fixed shaft 4 plays the role of supporting the rotating assembly 8, and at the same time, the fixed shaft 4 also plays the function of installing the non-contact switch assembly, thereby achieving a compact structure to complete the installation of multiple components.

[0057] Preferably, please refer to Figure 1 , 2 As shown in , 3 and 4, the switch bracket 3 includes a fixed cylinder and a horizontal frame, the fixed cylinder is used to be fixedly sleeved on the fixed shaft 4, the horizontal frame is fixedly connected to the outer wall of the fixed cylinder, and the horizontal frame is used to install multiple non-contact switches.

[0058] It can be understood that the overall installation and disassembly of the non-contact component can be achieved through the horizontal frame, which facilitates the assembly of the detection device.

[0059] Preferably, please refer to Figure 1 , 2 As shown in , 3 and 4, the horizontal frame is provided with mounting holes arranged in a row, and a clamping assembly is arranged in the mounting hole, and the clamping assembly is used to detachably clamp and fix the non-contact switch.

[0060] It can be understood that by clamping and fixing the non-contact switch on the horizontal frame through the clamping assembly, it is convenient to install and remove a single non-contact switch through the clamping assembly.

[0061] Preferably, please refer to Figure 1 , 2 As shown in , 3 and 4, the clamping assembly includes symmetrically arranged arc-shaped clamping plates, and the arc-shaped clamping plates are connected to the horizontal frame through springs.

[0062] It is understandable that the arc-shaped clamping plate can facilitate manual operation to clamp or remove the non-contact switch, which is conducive to improving the convenience of manual operation. It should be noted that a rubber pad can be provided on the inner wall of the arc-shaped clamping plate to improve the anti-slip effect of the arc-shaped clamping plate and protect the non-contact switch.

[0063] In another preferred embodiment of the utility model, the clamping assembly includes a limiting cylinder, which is used to pass through the mounting hole of the horizontal frame, and mounting platforms are provided on both sides of the limiting cylinder. The mounting platforms are used to fit the horizontal frame and connect and fix the mounting platforms to the horizontal frame by bolts, and the non-contact switch is arranged in the limiting cylinder and is tightened and fixed by square head bolts preset on the side wall of the limiting cylinder.

[0064] It can be understood that the limit cylinder is fixed in the mounting hole by bolts, and a square head bolt is provided on the inner wall of the limit cylinder. The non-contact switch inside the limit cylinder can be tightened and fixed by manually tightening the square head bolt, and manual operation is very convenient.

[0065] In another preferred embodiment of the present invention, the clamping assembly is arranged in an annular array as spring buckles on the inner wall of the mounting hole.

[0066] It can be understood that the non-contact switch is fixed in place by means of a spring buckle, which is convenient to operate and is conducive to replacing the non-contact switch or adjusting the position of the non-contact switch.
