DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the drawings.

[0017] The detection mechanism for detecting the height of compressor cylinder of the utility model, as shown in Figure 1 And Figure 2 It is shown that including stroke readable cylinder 1, the detection plate 2 for contacting the upper end surface of cylinder 99 and the gantry 3 for erecting above cylinder conveying line, and stroke readable cylinder 1 belongs to prior art, and stroke readable cylinder 1 can select the CEP1 series stroke readable cylinder (also called "measuring stroke cylinder") manufactured by SMC company, and stroke readable cylinder 1 includes cylinder body 101 and piston rod 102;As shown inFigure 4 As shown, the gantry frame 3 includes a top plate 301 and side foot plates 302. The front and rear ends of the top plate 301 are respectively fixedly connected to the upper ends of the corresponding side foot plates 302 by screws. Figure 1 and Figure 2 As shown, a top plate 301 is mounted and connected to the lower end of the cylinder body 101. The piston rod 102 passes through the top plate 301. A screw hole is provided at the lower end of the cylinder body 101, and a corresponding screw passes upward through the top plate 301 and connects to the screw hole. The detection plate 2 is located at the lower end of the piston rod 102; in other words, the detection plate 2 is located below the top plate 301. Figure 2 As shown, transparent curtains 6 are respectively installed on the left and right sides of the upper part of the gantry frame 3, and the detection plate 2 is located between the two transparent curtains 6. Figure 1 As shown, the lower side of the transparent curtain 6 is provided with a channel 300 for the cylinder 99 to pass through.

[0018] The working principle of this utility model is briefly explained below: Figures 1 to 3 As shown, the cylinder conveyor line includes cylinder conveying rollers 11 and a conveyor motor assembly. The conveyor motor assembly drives each cylinder conveying roller 11 to rotate via a chain. The cylinder conveyor line also has two cylinder guide rails 10, one at the front and one at the back, located above the cylinder conveying rollers 11. The cylinder conveyor line conveys cylinders 99 from left to right. The cylinders 99 move between the two cylinder guide rails 10. When the cylinder 99 passes through the gantry 3, the piston rod 102 of the stroke-readable cylinder 1 extends downward, causing the detection plate 2 to move down and abut against the upper surface of the cylinder 99. Since the cylinder 99 blocks the detection plate 2, the piston rod 102 stops moving. The stroke-readable cylinder 1 transmits the downward distance data of the piston rod 102 to the control system. The control system compares the above data with the input reference value. If the downward distance of the piston rod 102 is less than the reference value... If the difference exceeds the preset range, the controller can activate the alarm, allowing workshop personnel to know that the height dimension of the cylinder 99 is unqualified. After measurement, the control system controls the stroke-readable cylinder 1 to retract the piston rod 102 upwards, thus avoiding the need for manual measurement of the cylinder 99 with vernier calipers, preventing reading errors or measurement operation mistakes. Furthermore, the detection action of the stroke-readable cylinder 1 is only a simple downward movement, requiring a short time. Therefore, the detection mechanism of this invention helps improve detection efficiency and accuracy. Figure 1 and Figure 2As shown, since the detection plate 2 is located between the two transparent curtains 6 on the left and right, and the lower side of the transparent curtain 6 is provided with a channel 300 for the cylinder 99 to pass through, when the cylinder 99 passes through the gantry 3, the upper end of the cylinder 99 is close to the lower end of the transparent curtain 6, so that the piston rod 102 is surrounded by the transparent curtain 6 and the side foot plate 302, making it difficult for dust to adhere to the piston rod 102. When the piston rod 102 retracts upward, the sealing ring between the cylinder 101 and the piston rod 102 is not easy to come into contact with dust, which is beneficial to the durability of the sealing ring. Since the transparent curtain 6 is transparent, the operator can also observe the situation of the detection plate 2 contacting the upper surface of the cylinder 99 through the transparent curtain 6.

[0019] like Figure 3 As shown, a stop lever 81 can be set on the right side of the detection plate 2. The blocking cylinder 8 drives the stop lever 81 to move back and forth. A first diffuse reflection photoelectric sensor 12 is set on the right side of the detection plate 2. The first diffuse reflection photoelectric sensor 12 is used to detect the cylinder 99 located at the detection station. A second diffuse reflection photoelectric sensor 13 is set to the right of the first diffuse reflection photoelectric sensor 12. The second diffuse reflection photoelectric sensor 13 is used to detect the previous cylinder 99. The control system is electrically connected to the first diffuse reflection photoelectric sensor 12 and the second diffuse reflection photoelectric sensor 13. With the above setup, the previous cylinder 99 (i.e., the cylinder 99 that has been pushed to the right away from the detection station) triggers the second diffuse reflection photoelectric sensor 13. As the previous cylinder 99 is driven to the right by the corresponding cylinder conveying roller 11, and because the cylinder 99 is cylindrical, the second diffuse reflection photoelectric sensor 13 subsequently generates a disconnect signal (i.e., the previous cylinder 99 is no longer detected). The control system then controls the blocking cylinder 8 to drive the stop lever 81 to move forward based on the disconnect signal of the second diffuse reflection photoelectric sensor 13. Figure 3 As shown, the stop lever 81 is inserted to the left of the previous cylinder 99, enabling it to intercept the cylinder 99 at the detection station. Then, the first diffuse reflection photoelectric sensor 12 is triggered by the cylinder 99 at the detection station. The control system controls the piston rod 102 of the stroke readable cylinder 1 to move down according to the activation signal of the first diffuse reflection photoelectric sensor 12, detecting the height of the cylinder 99 at the detection station. After detection, if the height of the cylinder 99 is qualified, the control system controls the stop lever 81 to move backward and reset. Then, the cylinder 99 at the detection station moves to the right and leaves the detection station under the drive of the cylinder conveyor line. This cycle repeats. If the height of the cylinder 99 is not qualified, the control system keeps the stop lever 81 intercepting the cylinder 99 and issues an alarm. Through the above settings, the cylinder 99 can be stopped at the detection station with high precision, which is conducive to the automated detection of the cylinder 99 and further improves work efficiency.

[0020] Furthermore, such as Figure 1As shown, the top plate 301 is slidably connected to two guide rods 4 via corresponding linear bearings. The guide rods 4 are vertically arranged. A connecting plate 5 is installed at the lower end of the piston rod 102. Specifically, the connecting plate 5 is screwed to the lower end of the piston rod 102. A locking nut is screwed onto the piston rod 102 and rests against the upper side of the connecting plate 5. The connecting plate 5 is installed on the upper side of the detection plate 2 by corresponding screws. The lower ends of the corresponding guide rods 4 are respectively installed and connected to the front and rear ends of the connecting plate 5. Thus, through the guiding action of the two guide rods 4, the detection plate 2 can move vertically and linearly with high rigidity. This also avoids the reaction force of the cylinder 99 on the detection plate 2 causing the piston rod 102 to rotate, which would damage the stroke readable cylinder 1. After a long period of use, the detection plate 2 will be dented and deformed by the cylinder 99, at which point the detection plate 2 can be disassembled and replaced.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, the side panel 302 is fitted with a lower clamping strip 71 by corresponding screws. The lower end of the transparent curtain 6 is clamped between the side panel 302 and the lower clamping strip 71. Specifically, the rear end of the lower clamping strip 71 is connected to the side panel 302 located at the rear, and the front end of the lower clamping strip 71 is connected to the side panel 302 located at the front. The top panel 301 is fitted with an upper clamping strip 72 by corresponding screws. The upper end of the transparent curtain 6 is clamped between the top panel 301 and the upper clamping strip 72, thereby properly positioning the transparent curtain 6. The lower clamping strip 71 can be made of angle aluminum.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the detection mechanism of this utility model also includes a support base 9 for abutting the lower end face of the cylinder 99. The support base 9 is located below the detection plate 2. When the cylinder 99 moves to the detection station, the support base 9 supports the cylinder 99, and the detection plate 2 moves down and presses against the upper end face of the cylinder 99. Since the cylinder 99 is supported by the support base 9, it is prevented from easily swaying left and right, which helps to improve the detection accuracy. When the height of the detection cylinder 99 is completed, the next cylinder 99 (i.e., the cylinder 99 located on the left side of the detection station) is driven to move to the right by the cylinder conveying roller 11. The next cylinder 99 pushes the cylinder 99 located at the detection station to the right away from the support base 9. Figure 2 As shown, the support base 9 is located between two corresponding cylindrical conveying rollers 11.

[0023] Furthermore, the transparent curtain 6 is a polyethylene transparent curtain, that is to say, the transparent curtain 6 is made of polyethylene. More specifically, the transparent curtain 6 can be made of polyethylene film. The thickness of the transparent curtain 6 can be 0.5 mm to 1 mm. Since the transparent curtain 6 made of polyethylene has better flexibility, it can avoid the transparent curtain 6 being easily crushed by the upper clamping strip 72 or the lower clamping strip 71.
