A controller is connected with the electric telescopic rod 4 to control the electric telescopic rod 4. The bottom of the electric telescopic rod 4 is provided with a material clamping assembly 5. The first linear module 2, the second linear module 3, the electric telescopic rod 4 and the material clamping assembly 5 jointly constitute a plate moving unit.

[0063] The first linear module 2 and the second linear module 3 are connected with each other and arranged perpendicularly, so that the second linear module 3 slides on the first linear module 2. The plane on which the first linear module 2 and the second linear module 3 are arranged is a first plane. The electric telescopic rod 4 is connected with the bottom of the second linear module 3 and can move with the second linear module 3. The plane on which the electric telescopic rod 4 and the second linear module 3 are arranged is a second plane, and the second plane is perpendicular to the first plane. The material clamping assembly 5 is connected to the lower part of the electric telescopic rod 4.

[0064] In the embodiment, as shown in Figure 4 and 5 The material clamping assembly 5 includes a clamp shell 51. The bottom end of the piston rod of the electric telescopic rod 4 is fixedly connected with the clamp shell 51. The bottom of the two sides of the electric telescopic rod 4 is fixedly connected with a limiting block 52. The top of the two ends of the clamp shell 51 is fixedly connected with a sliding rod 53. The two sliding rods 53 are slidably connected with the two limiting blocks 52, respectively. A motor 54 is fixedly installed on one side of the clamp shell 51. The motor 54 is connected with the controller and is controlled to act by the controller. A bidirectional screw rod 55 is rotatably connected in the interior of the clamp shell 51. The output shaft of the motor 54 extends into the clamp shell 51 and is coaxially connected with the bidirectional screw rod 55. A sliding block 56 is symmetrically and threadedly connected to the outer side of the bidirectional screw rod 55. The sliding block 56 is slidably connected with the interior of the clamp shell 51. The bottom of the clamp shell 51 is also symmetrically provided with a clamping plate 57. The top of the clamping plate 57 extends into the interior of the clamp shell 51 and is fixedly connected with the bottom of the sliding block 56.

[0065] In the above embodiment, the first linear module 2 can drive the second linear module 3 to move in the X-axis direction in the horizontal plane. The second linear module 3 drives the electric telescopic rod 4 to move in the Y-axis direction in the horizontal plane. The electric telescopic rod 4 moves the material clamping assembly 5 up and down in the vertical plane. The material clamping assembly 5 drives the bidirectional screw rod 55 to rotate through the motor 54, so that the two sliding blocks 56 move close to or away from each other, and the clamping plate 57 moves close to or away from each other, thereby clamping the plate. The plate is moved in the cabinet 1 by the first linear module 2, the second linear module 3 and the electric telescopic rod 4.

[0066] As an embodiment of the present application, the clamping plates 57 are arc-shaped structures, and each of the two clamping plates 57 is provided with a flange at a bottom near one side, so as to facilitate stable clamping of the printing plate and prevent the printing plate from falling off.

[0067] The first linear module 2, the second linear module 3 and the material clamping assembly 5 together realize the movement of the printing plate from the first position to the printing plate detection unit.

[0068] As an embodiment of the present application, the printing plate detection unit comprises a temperature and humidity detection assembly 6 and a thickness detection assembly 7; the temperature and humidity detection assembly 6 is used for temperature detection and humidity detection of the printing plate to obtain a temperature and humidity detection result; and the thickness detection assembly 7 is used for thickness detection of the printing plate to obtain a thickness detection result.

[0069] Specifically, as shown in Figure 6 the temperature and humidity detection assembly 6 is arranged below the first plane and within the moving range of the material clamping assembly 5, and is used for temperature detection and humidity detection of the printing plate clamped by the material clamping assembly 5 to obtain a temperature and humidity detection result.

[0070] The temperature and humidity detection assembly 6 comprises a first placement seat 62 for carrying the printing plate; a temperature and humidity sensor 63 is mounted at the top middle portion of the first placement seat 62; and the temperature and humidity sensor 63 is connected to the controller and is used for obtaining a temperature and humidity detection result of the printing plate and feeding back to the controller.

[0071] In the above embodiment, the temperature and humidity detection assembly 6 comprises a first bottom plate 61 fixedly connected to one end of the inner wall bottom of the cabinet 1, and the first bottom plate 61 is fixedly installed with the first placement seat 62 at the top thereof, and the first placement seat 62 is installed with the temperature and humidity sensor 63 at the top middle portion thereof.

[0072] When the printing plate moving unit drives the printing plate to move to the first placement seat 62 of the temperature and humidity detection assembly 6, the temperature and humidity sensor 63 is in contact with the printing plate to monitor the temperature and humidity of the printing plate.

[0073] Specifically, as shown in Figure 7 the thickness detection assembly 7 is arranged below the first plane and within the moving range of the material clamping assembly 5, and is used for thickness detection of the printing plate clamped by the material clamping assembly 5 to obtain a thickness detection result.

[0074] The thickness detection assembly 7 comprises a second placement seat 72 for bearing the printing plate and a side plate 73. One side of the side plate 73 is fixedly provided with a rotary air cylinder 74 connected with a controller and controlled by the controller to move. An output shaft of the rotary air cylinder 74 extends to the other side of the side plate 73 and is fixedly connected with a rotating rod 75. The upper end of the rotating rod 75 is connected with a pressure plate 76 through a universal ball head near one side of the second placement seat 72. A thickness detection sensor is arranged on the rotating rod 75 and connected with the controller to obtain the height of the pressure plate 76 in the pressing state, convert the thickness detection result of the printing plate and feed back to the controller.

[0075] In the embodiment, the rotating shaft of the rotating rod 75 is higher than the top surface of the second placement seat 72. When the pressure plate 76 reaches the pressing state, the pressure plate 76 is located directly above the second placement seat 72.

[0076] In the embodiment, the pressure plate 76 is a circular roller and has a certain contact surface with the printing plate to prevent damage to the printing plate.

[0077] In the above embodiment, the top surfaces of the first placement seat 62 and the second placement seat 72 are completely covered by the printing plate in the state of placing the printing plate.

[0078] In the above embodiment, the top surfaces of the first placement seat 62 and the second placement seat 72 are circular and are attached with release paper. However, the temperature and humidity sensor 63 of the first placement seat 62 does not have release paper at the corresponding top position. The release paper is a kind of anti-sticking paper which can prevent the prepreg from sticking and protect the prepreg from being polluted.

[0079] In another embodiment of the above embodiment, the thickness detection assembly 7 can further comprise a second bottom plate 71 fixedly connected with the inner wall bottom of the cabinet 1 and away from the temperature and humidity detection assembly 6. The second bottom plate 71 is fixedly provided with the second placement seat 72 at the top middle part and is fixedly connected with the side plate 73 at one end of the top.

[0080] As an embodiment of the present application, a thickness scale display can be further added. Specifically, a scale can be arranged on the side plate 73. The scale is arc-shaped and away from the second placement seat 72. Figure 8 As shown in the figure, a magnifying glass is embedded in the middle of the scale observation block 77. The magnifying glass is used to observe the scale of the scale. The middle of the magnifying glass is marked with a sight, which is convenient for better observing the scale. The scale of the same position of the rotary air cylinder 74 is observed through the scale observation block 77, so that the thickness of the printing plate can be further intuitively understood.

[0081] As an embodiment of the present application,Figure 1 As shown, the device further comprises a control panel 8. The control panel 8 is arranged outside the cabinet 1, and the control panel 8 is connected to the controller, for operating the control panel 8 to input control instructions to the controller.

[0082] In the embodiment, the printing plate is moved to the temperature and humidity detection assembly 6 by the printing plate moving unit for detection. When the printing plate moving unit moves the printing plate to the first placement seat 62 of the temperature and humidity detection assembly 6, the temperature and humidity sensor 63 contacts the printing plate to detect the temperature and humidity, to check whether the printing plate is dry and suitable, and whether the temperature is within the error range, to judge the fault of the heating unit of the gum developing machine. Then, the printing plate is moved to the thickness detection assembly 7. When the printing plate moving unit moves the printing plate to the second placement seat 72 of the thickness detection assembly 7, the controller controls the rotary air cylinder 74 to rotate the rotating rod 75, and the pressing plate 76 is pressed on the printing plate. The thickness detection result when the pressing plate 76 is in the pressing state is fed back by the thickness detection sensor, to judge the thickness detection result, to judge whether the thickness after the gum is dried is up to the standard. If not, it means that the gum outlet unit of the gum developing machine is not faulty, so that the printing plate can be executed to the next process.

[0083] The above specific embodiments do not constitute a limitation on the protection scope of the present application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements within the spirit and principles of the present application shall be included in the protection scope of the present application.
