Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing machines, in particular to a leak-proof hot pressing induction device. Background Art

[0002] A laptop is a portable personal computer with the advantages of small size, light weight, and easy to carry and move.

[0003] In the prior art, after the staff has placed the notebook shell in the hot press, it is easy for them to forget to press the start button. When the staff sends in the next shell, they may mistakenly think that the shell placed in the hot press has been hot pressed. Since the shells on both sides will stick together after the glue comes into contact, the staff cannot tell with the naked eye whether the shell has been hot pressed when taking out the shell. At this time, the shell that has not completed hot pressing is prone to debonding after being sent to the next processing link, resulting in a low yield rate of the hot pressing production line. Utility Model Content

[0004] The utility model mainly provides a leak-proof hot-pressure sensing device which can sense and find out the missed pressing of a start button and improve the yield rate.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a leak-proof hot pressure sensing device, including a processing table, a placing rack is fixedly connected to the bottom of the processing table, a center hole is opened in the bottom of the placing rack, an infrared distance sensor is fixedly connected to the bottom of the processing table, a first hydraulic rod is fixedly connected to the top of the processing table, the output end of the first hydraulic rod slides through the processing table and extends to the inside, the output end of the first hydraulic rod is fixedly connected to a support plate, the bottom of the support plate is fixedly connected to a hot pressing plate, the top of the processing table is fixedly connected to a time relay, and the top of the processing table is fixedly connected to an alarm.

[0006] Preferably, the infrared distance sensor is located at the lower side of the placement rack, and the infrared distance sensor cooperates with the center hole position. After the workpiece to be hot-pressed is placed inside the placement rack, the workpiece will block the center hole position. At this time, the infrared signal emitted by the infrared distance sensor can detect that the workpiece is placed in place.

[0007] Preferably, the infrared distance sensor is electrically connected to the time relay, the time relay is electrically connected to the alarm, the hot pressing plate is coordinated with the placement rack position, and after the workpiece is placed and triggers the infrared distance sensor threshold, the time relay can be controlled to start. The preset time of the time relay is 30-60 seconds. After the normal timing of the time relay ends, it means that the hot pressing plate has not been started into place. At this time, the time relay ends the timing control to start the alarm, and the alarm sends out an audible and visual alarm signal to remind the staff that the hot pressing button has not been started.

[0008] Preferably, a side frame is fixedly connected to the top of the support plate, and an infrared counter-radiation sensor is fixedly connected to the outer surface of the side frame. The infrared counter-radiation sensor is electrically connected to a time relay. When the workpiece is hot-pressed, the staff presses a start hot-pressing button to control the first hydraulic rod to start extending. The first hydraulic rod drives the hot-pressing plate downward through the connection with the support plate, and the hot-pressing plate moves down to the placement frame position to hot-press the workpiece.

[0009] Preferably, a bracket is fixedly connected to the bottom of the processing table, and a radiation receiver is fixedly connected to the outer surface of the bracket. The radiation receiver is matched with the infrared radiation sensor. When the hot pressing plate moves down to the position of the bracket for hot pressing, the infrared radiation sensor moves down to the position of the bracket corresponding to the position of the radiation receiver. At this time, the infrared signal emitted by the infrared radiation sensor senses the radiation receiver. After the infrared radiation sensor is triggered, the time relay is reset and the timing is continued when the workpiece is put in next time.

[0010] Preferably, a second hydraulic rod is fixedly connected to the outer surfaces of both sides of the processing table, the output end of the second hydraulic rod slides through the processing table and extends to the inner side, the output end of the second hydraulic rod is fixedly connected to a push plate, and the outer surface of the push plate is fixedly connected to a wedge plate. When the timing of the time relay ends, the second hydraulic rod is controlled to start, and the start-up extension of the second hydraulic rod can drive the push plate and the wedge plate to move toward the workpiece, and the inclined surface of the wedge plate can be inserted into the gap between the upper and lower workpieces to push the two workpieces apart and separate them. The time relay and the second hydraulic rod cooperate to find that the two workpieces are separated after the hot pressing is not started, so as to avoid the glue solidifying and being unable to be cleaned when the workpieces are in contact for a long time, so that the workpieces can be reworked and repaired in time, thereby reducing the generation of waste.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when hot pressing is performed after the glue is dispensed on the notebook shell, after the workpiece is placed, the infrared signal emitted by the infrared distance sensor can detect that the workpiece is in place and control the start of the time relay. After the normal timing of the time relay ends, it means that the hot pressing plate has not been started in place and the staff has forgotten to press the start button. At this time, the time relay ends the timing control to start the alarm, and the alarm emits an audible and visual alarm signal to remind the staff that the hot pressing button has not been started, which effectively avoids the problem of the staff forgetting to press the start button and the workpiece leaking hot pressing.

[0013] 2. In the utility model, when the alarm is activated, the time relay will control the activation of the second hydraulic rod. The activation and extension of the second hydraulic rod can drive the push plate and the wedge plate to move toward the workpiece. The inclined surface of the wedge plate can be inserted into the gap between the upper and lower workpieces to push the two workpieces apart, thereby preventing the glue from solidifying and being unable to be cleaned when the workpieces are in contact for a long time. The workpieces can be reworked and repaired in time, thereby reducing the generation of waste. BRIEF DESCRIPTION OF THE DRAWINGS

After the workpiece to be hot-pressed is placed inside the placement rack 2, the workpiece will block the position of the center hole 3. At this time, the infrared signal emitted by the infrared distance sensor 4 can detect that the workpiece is placed in place.

[0024] like Figure 1-Figure 4 As shown, a side frame 8 is fixedly connected to the top of the support plate 6, and an infrared counter-radiation sensor 9 is fixedly connected to the outer surface of the side frame 8. The infrared counter-radiation sensor 9 is electrically connected to the time relay 12. When the workpiece is hot-pressed, the staff presses the hot-pressing start button to control the first hydraulic rod 5 to start extending. The first hydraulic rod 5 drives the hot-pressing plate 7 to move downward through the connection with the support plate 6, and the hot-pressing plate 7 moves downward to the placement frame 2 to hot-press the workpiece.

At this time, the infrared signal emitted by the infrared beam sensor 9 senses the beam receiver 11. After the infrared beam sensor 9 is triggered, the time relay 12 is controlled to reset, waiting for the next time the workpiece is put in to continue to start the timing.

[0026] like Figure 1-Figure 4 As shown, the outer surfaces of both sides of the processing table 1 are fixedly connected with second hydraulic rods 14, the output end of the second hydraulic rod 14 slides through the processing table 1 and extends to the inside, the output end of the second hydraulic rod 14 is fixedly connected with a push plate 15, and the outer surface of the push plate 15 is fixedly connected with a wedge plate 16.

The preset time of the time relay 12 is 30-60 seconds. After the normal timing of the time relay 12 ends, it means that the hot pressing plate 7 has not started in place and the staff has forgotten to press the start button. At this time, the time relay 12 ends the timing control to start the alarm 13. The alarm 13 emits an audible and visual alarm signal to remind the staff that the hot pressing button has not been started. When the alarm 13 is started, the time relay 12 will control the start of the second hydraulic rod 14.
