[0030] Please combine Figures 1 to 3 In view of the problem that the current automatic binding machine has unqualified binding due to the positioning pin 1 not being inserted into the bottom of the lower rivet head 41, the present application provides an automatic binding machine binding detection device, which includes a positioning pin 1, a riveting slide block 2, an upper riveting component 3 and a lower riveting component 4. The positioning pin 1 is inserted into the riveting slide block 2 and can slide relative to the riveting slide block 2. The upper riveting component 3 is arranged at the bottom of the riveting slide block 2, and the lower riveting component 4 is located directly below the upper riveting component 3. The positioning pin 1 passes through the upper riveting component 3 and its bottom can be inserted into the lower riveting component 4 for binding positioning. The present application uses light sensing detection technology to detect whether the positioning pin 1 is inserted into place to improve the reliability and stability of binding.

[0031] Specifically, a light sensing detection component 5 is provided on the top of the riveting sliding block 2, and a covering member 6 is provided on the positioning pin 1. When the positioning pin 1 descends and is inserted into the lower riveting component 4, the covering member 6 moves with the movement of the positioning pin 1. When the bottom end of the positioning pin 1 is inserted into the target position of the lower riveting component 4, the covering member 6 completely covers the light sensing detection component 5, thereby achieving the purpose of detecting whether the positioning pin 1 is inserted into the bottom of the lower riveting component 4.

[0032] The light sensing detection component 5 of the present application includes a detection shell forming a groove structure, and a light source transmitter and a light source and a receiver are respectively arranged on both sides of the detection shell. The light source transmitter transmits a photoelectric signal to the light source receiver, and the light source receiver can send the photoelectric signal detected by it to the host in real time. The host is used to control the operation of the entire automatic binding machine. The cover 6 includes a cap that can be inserted into the groove structure of the detection shell to separate the light source transmitter and the light source receiver. The cap is fixed to the upper end of the positioning pin 1 by a threaded fastener, and the distance from the cap to the light sensing detection component 5 is equal to the distance from the bottom of the positioning pin 1 to the lower riveting component 4. When the bottom of the positioning pin 1 is inserted into the target position of the lower riveting component 4, the cap on the positioning pin 1 is also inserted into the groove structure of the detection shell to completely isolate the photoelectric signal emitted by the light source transmitter, so that the light source receiver cannot receive any photoelectric signal.

[0033] In addition, since the cap is fixed to the positioning pin 1 by a threaded fastener, the position of the cap on the positioning pin 1 can be adjusted according to the distance from the bottom end of the positioning pin 1 to the lower riveting assembly 4 to adapt to the use of binding machines of different specifications.

[0034] The binding detection device of the automatic binding machine of the present application also includes a voice reminder module electrically connected to the host, and the voice reminder module is used to send a voice reminder signal according to the photoelectric detection signal of the light sensing detection component 5 received by the host, that is, when the positioning pin 1 is not plugged into place with the lower riveting component 4, the light source receiver of the light sensing detection component 5 can still receive the photoelectric signal emitted by the light source transmitter, and the host receives the photoelectric signal and sends a control signal to the voice reminder module. The voice reminder module includes a speaker, that is, when the voice reminder module receives the control signal of the host and when the user starts the binding machine, the speaker sends a voice reminder to remind the user to plug the positioning pin 1 into place, thereby solving the problem of unqualified riveting or even inability to perform normal binding due to the positioning pin 1 not being plugged into place, and greatly improving the reliability and stability of binding.

[0035] A cushion block 7 is provided between the bottom of the detection shell of the light-sensing detection component 5 of the present application and the top of the riveting slide block 2. The light-sensing detection component 5 is clamped on the cushion block 7, and the cushion block 7 is fixed to the top of the riveting slide block 2 by screws. The cushion block 7 can buffer the impact force of the cap falling with the positioning pin 1 and inserting into the light-sensing detection component 5, thereby reducing damage to the light-sensing detection component 5 and the riveting slide block 2. At the same time, the cushion blocks 7 of different thicknesses can be replaced to meet the requirement that the distance from the cap to the light-sensing detection component 5 is equal to the distance from the bottom of the positioning pin 1 to the lower riveting component 4, which can play the role of installing, fixing, protecting and adjusting the height position of the light-sensing detection component 5.

[0036] A positioning needle cap 11 is provided on the top of the positioning needle 1, and the positioning needle cap 11 can facilitate the user to operate the lifting and lowering of the positioning needle 1. The positioning needle 1 is made of rubber, which can also prevent the top of the positioning needle 1 from hurting the user, thereby playing a protective role.

[0037] The rivet slide block 2 of the present application comprises a first rivet block 21 and a second rivet block 22 which are connected in a left-right matching manner. A through slot 23 is provided between the first rivet block 21 and the second rivet block 22 for the positioning pin 1 to pass through. The positioning pin 1 can slide relatively freely in the through slot 23. At the same time, a mounting slot 24 for the upper riveting assembly 3 to be installed is provided at the bottom of the rivet slide block 2. The upper riveting assembly 3 comprises an upper rivet head 31, an upper rivet head 31 gasket and an upper rivet head 31 fixing block. The upper rivet head 31 is installed in the mounting slot 24 at the bottom of the rivet slide block 2 through the upper rivet head 31 fixing block, so that the rivet slide block 2 can move with the upper rivet head 31. The upper rivet head 31 gasket is installed on the inner side of the upper rivet head 31 close to the mounting slot 24, so as to increase the friction between the upper rivet head 31 and the rivet slide block 2 and reduce the relative rotation between the upper rivet assembly 3 and the rivet slide block 2. In addition, a through hole for the positioning pin 1 to pass through is provided on the upper rivet head 31 and the upper rivet head 31 gasket.

[0038] The lower riveting assembly 4 is located directly below the upper riveting assembly 3, and includes a lower rivet head 41 and a lower rivet head 41 fixing seat. The lower rivet head 41 is installed in the lower rivet head 41 fixing seat, and the lower rivet head 41 is provided with a plug-in slot 411 for inserting the bottom end of the positioning pin 1. The bottom of the plug-in slot 411 of the present application is the target position for inserting the positioning pin 1 into the lower riveting assembly 4. The present application satisfies the binding conditions of the automatic binding machine by inserting the positioning pin 1 into the target position of the lower riveting assembly 4, that is, the bottom of the positioning pin 1 is inserted into the bottom of the lower rivet head 41.

[0039] The automatic binding machine binding detection device of the present application can move the positioning pin 1 downward to be inserted into the lower riveting component 4 before the binding operation of the automatic binding machine, and the cover 6 moves downward with the positioning pin 1 to be inserted into the light sensing detection component 5. If the positioning pin 1 is not inserted into the bottom of the lower rivet head 41, that is, the cover 6 does not completely cover the light sensing detection component 5, when the user presses the binding start button of the automatic binding machine, the host receives the photoelectric signal fed back by the light sensing detection component 5, that is, it is detected that the positioning pin 1 is not inserted into the bottom of the lower rivet head 41 at this time, and the voice reminder module can issue a voice prompt "Please insert the positioning pin 1 to the bottom" to remind the user that the positioning pin 1 needs to be inserted into the bottom of the lower rivet head 41; when the cover 6 completely blocks the light sensing detection component 5, when the binding start button of the automatic binding machine is pressed, the host cannot receive the photoelectric signal fed back by the light sensing detection component 5, indicating that the bottom end of the positioning pin 1 has been inserted into the bottom of the lower rivet head 41 at this time, and normal binding can be performed.

[0040] In summary, the binding detection device of the automatic binding machine of the present application has a simple structure. It detects whether the bottom of the positioning pin 1 is inserted into the lower rivet head 41 by adopting light sensing detection technology in conjunction with the relative sliding between the positioning pin 1 and the riveting sliding block 2, thereby reducing the situation where the riveting pressure fails due to the positioning pin 1 not being inserted into place, or even causing re-riveting, reducing the user's binding time, improving efficiency, reducing the loss of consumables, and greatly improving the reliability and stability of binding.

[0041] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
