[0002] In the field of industrial production, it is often necessary to process or test the performance of products on the assembly line. Traditional processes often require the work object to stay at a certain station for processing or testing, which will cause the production line to stop, affecting the previous and subsequent processing steps, and further affecting the production efficiency of the entire assembly line. Therefore, a device that can follow the movement of the processing object or the detection object came into being.

The space above the room is utilized. Compared with ground installation, it will not affect the normal progress of other processes, improve space utilization, and adopt a rolling friction method. It has better quietness, maintenance-free in the later stage, no oiling is required, and the workload of personnel is reduced. However, the guide rail motion mechanism in the accompanying mechanism is relatively complex, which is not convenient for installation and maintenance. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a guide rail running mechanism and a guide rail accompanying detection device which are simple in structure and easy to install and maintain.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provided is a guide rail operating mechanism, comprising a frame, a driving wheel, a sliding assembly and a driving assembly, wherein the driving wheel is rotatably connected to the frame, the driving assembly is mounted on the frame and the output shaft is connected to the driving wheel, the sliding assembly is connected to the frame, and a space is left between the sliding assembly and the driving wheel for the guide rail to pass through.

[0007] With this arrangement, when in use, the external device required for operation is fixedly connected to the frame, and the guide rail operating mechanism is installed on the guide rail, so that the guide rail is located between the driving wheel and the sliding assembly. The driving assembly can drive the driving wheel to rotate forward or reverse, and the driving wheel moves relative to the guide rail, thereby driving the guide rail operating mechanism as a whole to slide on the guide rail.

[0008] Preferably, the frame includes a first fixed shaft and two clamping plates, the two clamping plates are arranged in parallel, the first fixed shaft passes through the two clamping plates, and the driving wheel is arranged between the two clamping plates and is rotatably connected to the clamping plates.

[0009] Furthermore, a bearing is provided at the connection between the driving wheel and the clamping plate, and the bearing can greatly reduce the rolling friction between the driving wheel and the clamping plate, thereby reducing power loss and equipment wear.

[0010] Preferably, the driving assembly is protruding from the outside of the frame, and the driving assembly includes a motor and a reducer, the motor is connected to the reducer, the reducer is connected to the frame, and the output end of the reducer is also connected to the driving wheel, and the reducer can transmit the motor output torque to the driving wheel.

[0011] With this arrangement, the motor can drive the driving wheel to rotate via the reducer, and the reducer can amplify the output torque of the motor. When the guide rail operating mechanism carries a device with a large mass, the drive component can also output sufficient power to allow the guide rail operating mechanism to slide on the guide rail.

[0012] Preferably, the motor and the reducer are arranged vertically, and the motor can be used to clamp and install an external device.

[0013] Through this arrangement, the motor and the reducer are combined into a handle structure, and the external device required for processing or inspection can be installed on the guide rail running mechanism by connecting the motor card to the external device, thereby saving installation space and reducing the connection structure, making the structure of the guide rail running mechanism simpler, reducing costs and saving space.

[0014] Preferably, the sliding assembly is arranged beside the driving wheel, and the sliding assembly includes a movable plate, a second fixed shaft and a driven wheel. One end of the movable plate is rotatably connected to the frame through the second fixed shaft, and the other end is connected to the frame. The driven wheel is rotatably connected to the movable plate, and a space is left between the driven wheel and the driving wheel for the guide rail to pass through.

[0015] With this arrangement, the guide rail is passed between the driving wheel and the driven wheel, and the guide rail is limited by the driving wheel and the driven wheel. When the driving wheel is driven to rotate by the motor, the driven wheel rolls on the guide rail, and there is rolling friction between the driven wheel and the guide rail, thereby reducing resistance and making the displacement of the guide rail operating mechanism on the guide rail smoother.

[0016] Preferably, the number of the driven wheels is 2 or more, and they are symmetrically arranged on both sides of the movable plate in groups of two.

[0017] In this setting method, the driven wheels on both sides can jointly form a "pin" - shaped structure with the driving wheel, so that the guide rail is limited in the middle of the driven wheel and the driving wheel, which can effectively prevent the guide rail running mechanism from tipping over on the guide rail.

[0018] Preferably, an arc - shaped notch for accommodating the driving wheel is further provided on the movable plate. The arc - shaped notch is located at the bottom of the movable plate, and the driven wheel is located at the top of the movable plate.

[0019] Through this setting method, the structure between the driving wheel and the driven wheel can be made more compact, further reducing the space of the guide rail running mechanism and realizing the light - weight of the device.

[0020] Preferably, the guide rail running mechanism further includes an adjustment assembly, and the sliding assembly is movably connected to the frame through the adjustment assembly.

[0021] Through this setting method, when installing the guide rail running mechanism on the guide rail, the distance between the sliding assembly and the driving wheel can be adjusted through the adjustment assembly, so that the guide rail running mechanism can be adapted to guide rails of different specifications, expanding the applicable range of the guide rail running mechanism.

[0022] Preferably, the adjustment assembly includes an adjustment block, an adjustment rod, a third fixed shaft, a spring and an adjustment nut. The adjustment block is rotatably connected to the movable plate. The two ends of the third fixed shaft are respectively fixedly connected to two clamping plates. The end of the adjustment rod is fixedly connected to the adjustment block. The adjustment rod movably passes through the third fixed shaft. The adjustment nut is threadedly connected to the adjustment rod at a position away from the adjustment block. The spring is sleeved on the adjustment rod, and the spring is between the third fixed shaft and the adjustment nut, and the spring is in a compressed state.

[0023] Through this setting method, when it is necessary to shorten the distance between the sliding assembly and the driving wheel, the transient method is used to analyze the adjustment assembly. First, adjust the position of the adjustment nut on the adjustment rod to make the adjustment nut move towards the third fixed shaft. At this time, the spring is compressed. Also, because one end of the spring abuts against the third fixed shaft, that is, the abutting end of the spring and the third fixed shaft is the fixed end, and the elastic force of the spring increases after being compressed by the adjustment nut, so the adjustment nut is pushed away from the third fixed shaft. The adjustment nut drives the adjustment rod to move, making the section of the adjustment rod between the adjustment block and the third fixed shaft shorter. Coupled with the rotation of the adjustment block, the distance between the sliding assembly and the driving wheel is shortened. When it is necessary to increase the distance between the sliding assembly and the driving wheel, vice versa.

[0024] Furthermore, the adjustment nut includes two hexagonal nuts. Through this setting method, the cooperative locking of the two hexagonal nuts can ensure stable installation, avoiding the displacement of a single nut under the continuous pressure of the spring, which affects the installation stability.

[0025] A guide rail accompanying detection device comprises the guide rail operating mechanism, an electric cabinet, a detection machine, a guide rail and a conveyor belt according to any one of the above items, wherein the guide rail and the conveyor belt are arranged in parallel, the guide rail operating mechanism is slidably connected to the guide rail, the driving wheel and the sliding assembly are movably connected to the guide rail, the detection machine is fixedly connected to the guide rail operating mechanism, and the electric cabinet is electrically connected to the conveyor belt and the guide rail operating mechanism.

[0026] Through this setting, the user can control the movement of the guide rail operating mechanism on the guide rail and the movement of the conveyor belt through the electrical cabinet. The electrical cabinet can set the movement trajectory of the guide rail operating mechanism according to the needs of actual production, so that the guide rail operating mechanism can follow the displacement of the detection object on the conveyor belt, and perform detection through the detection machine installed on the guide rail operating mechanism.

[0027] Preferably, the guide rail is provided with an I-shaped groove, the driven wheel and the driving wheel are both installed in the I-shaped groove and are located at the upper and lower sides respectively, and the driving wheel and the driven wheel are both in contact with the guide rail. Through this arrangement, the driven wheel and the driving wheel are in contact with the guide rail at the upper and lower sides in the I-shaped groove respectively, and the movable plate can pass through the channel in the middle of the I-shaped groove, so that the guide rail running mechanism and the guide rail are closely matched, and the reciprocating drive assembly is prevented from falling off the guide rail.

[0028] Preferably, a buffer is further provided at the end of the movable plate, and a limit block is provided on the guide rail, and the buffer can abut against the limit block. When the buffer abuts against the limit block, the guide rail running mechanism will stop on the guide rail.

[0029] With this arrangement, when unexpected situations such as operating errors or electrical control failures occur, the limit block can prevent the guide rail running mechanism from rushing out of the end of the guide rail through physical limiting, and the buffer part can act as a buffer between the guide rail running mechanism and the limit block, thereby minimizing the damage to the guide rail running mechanism during emergency stop.

[0030] Compared with the prior art, the beneficial effects of the utility model are:

[0031] (1) The structure is greatly simplified while ensuring the moving effect, which facilitates installation and reduces costs.

[0032] (2) An adjustment component is provided between the slide component and the frame, so that the distance between the slide component and the driving wheel can be adjusted as needed, thereby adapting to guide rails of different sizes and expanding the scope of use.

[0050] During operation, the guide rail 6 is passed between the driving wheel 2 and the driven wheel 33, and the guide rail 6 is limited by the driving wheel 2 and the driven wheel 33. When the driving wheel 2 is driven by the driving component 4 to rotate, the driven wheel 33 rolls on the guide rail 6, and there is rolling friction between the driven wheel 33 and the guide rail 6, thereby reducing resistance and making the displacement of the guide rail operating mechanism on the guide rail 6 smoother.

[0051] As an embodiment of the present utility model, the guide rail 6 is disposed between the driving wheel 2 and the driven wheel 33. The guide rail 6 is limited by the driving wheel 2 and the driven wheel 33. When the driving wheel 2 is driven by the motor 41 to rotate, the driven wheel 33 rolls on the guide rail 6.
