Description

Technical Field

[0001] The utility model belongs to the technical field of printing manufacturing, and in particular relates to a verticality detection system for a PS plate. Background Art

[0002] PS plate is a pre-s-sensitized plate. During the production process, the PS plate will be cut according to the size required by the customer. Therefore, there will be errors in the verticality of each PS plate. The error may be too large and exceed the error range. Therefore, it is necessary to detect the verticality of the plate in time to ensure that the verticality of each PS plate is within the required range. The existing measurement method generally uses molds or protractor equipment for detection. On the one hand, the use of molds for detection increases the cost of mold opening. On the other hand, the use of protractor measurement has low measurement efficiency, high requirements for workers' operation, and easy measurement errors. Therefore, a fast and easy-to-operate PS plate verticality detection system is urgently needed. Summary of the invention

[0003] The utility model provides a PS plate verticality detection system to solve the technical problems existing in the background technology.

[0004] The technical solution of the utility model is as follows: A PS plate verticality detection system, comprising: a supporting back plate, a card slot, a limit block, a limit slider, a first displacement sensor, a second displacement sensor, a processing device and a display device;

[0005] The supporting back plate is tilted, the card slot is horizontally installed at the bottom of the supporting back plate, the limiting block is fixed in the card slot, and the limiting slider is slidably arranged in the card slot;

[0006] The first displacement sensor and the second displacement sensor are arranged in the width direction of the supporting back plate, the first displacement sensor and the second displacement sensor are connected in communication with the processing device, and the processing device is connected in communication with the display device.

[0007] Furthermore, the supporting back plate is installed on an equipment frame, and a support foot is provided at the bottom of the equipment frame.

[0008] Furthermore, the processing device is connected to a foot switch.

[0009] Furthermore, the processing device is a PLC processor.

[0010] The beneficial effects of the utility model are as follows: the utility model places the plate to be tested on an inclined supporting back plate, then slides it down into the card slot, moves the plate to a suitable position through a limit block and a limit slider, and detects the verticality of the plate through two displacement sensors. The utility model has a simple structure, low operation difficulty, and is easy to use. Whether the verticality of the plate meets the standard can be directly distinguished through the value on the display screen. The detection speed is fast, the requirements for worker operation are low, and the demand for production efficiency can be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0014] In an embodiment of the present utility model, Figure 1 and Figure 2 It is a structural schematic diagram provided according to the specific structure of a PS plate verticality detection system of the utility model, such as Figure 1 As shown, the utility model specifically includes:

[0015] Support back plate 6, card slot 10, limit block 5, limit slider 9, first displacement sensor 2, second displacement sensor 3, processing equipment and display device 1; the support back plate 6 is tilted, specifically, the support back plate 6 is installed on the equipment frame 7, and the bottom of the equipment frame 7 is provided with a support foot.

[0016] The card slot 10 is horizontally installed at the bottom of the supporting back plate 6 , the limiting block 5 is fixed in the card slot 10 , and the limiting sliding block 9 is slidably disposed in the card slot 10 .

[0017] The first displacement sensor 2 and the second displacement sensor 3 are arranged in the width direction of the support back plate 6, and the first displacement sensor 2 and the second displacement sensor 3 are arranged up and down. The first displacement sensor 2 and the second displacement sensor 3 are connected to the processing device for communication, and the processing device is connected to the display device 1 for communication. The processing device is a PLC processor, and the display device is a display screen. The PLC processor processes the data of the two sensors, converts the signals of the sensors into detection parameters, calculates the deviation value through the two detection parameters, and displays it through the display screen.

[0018] The processing device is connected to a foot switch 8, and the foot switch is used to control the processor to collect signals from the two displacement sensors.

[0019] The use of the utility model is as follows: first slide the limit slider 9 to the rightmost side, then place the PS plate 4 to be tested on the support back plate 6, so that the PS plate 4 to be tested is completely fitted with the support back plate 6, and the PS plate 4 to be tested will slowly slide down by gravity until the PS plate 4 to be tested slides down into the card slot 10. At this time, the lower edge of the PS plate 4 to be tested is completely fitted with the card slot 10, and the limit slider 9 is manually moved slowly to the left, and then the limit slider 9 contacts the PS plate 4 to be tested, driving the PS plate 4 to be tested to move to the left together. When the PS plate 4 to be tested touches the limit block 5, stop pushing the limit slider 9. At this time, the PS plate 4 to be tested has been placed in the reference position and is ready for detection. The position of the first displacement sensor 2 or the second displacement sensor 3 is manually adjusted (the appropriate displacement sensor is selected according to the height of the plate). When the PS plate 4 to be tested is in the reference position, the ejector pin of the displacement sensor touches the left edge of the detection plate. At this time, the operator observes the display device 1 and compares the inspection standard according to the detection value of the display device 1, thereby judging whether the verticality of the product is qualified.

[0020] The utility model manually places the PS plate to be tested in the card slot, aligns a right angle of the plate with the reference point, measures the distance to the edge through two displacement sensors on the side, feeds the measured value back to the PLC, and calculates the verticality through the program.

[0021] The utility model can timely and effectively detect the produced plates to prevent the entire batch of products from being scrapped due to dimensional errors caused by equipment during the production process. At the same time, defective products can be discovered in time and the equipment can be adjusted immediately to reduce the scrap rate.

[0022] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
