[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 7The nail insertion device of this embodiment includes: a driving assembly; at least two clamping jaws 151, which are arranged on the driving assembly, and the driving assembly can drive the at least two clamping jaws 151 to clamp; a detection rod 144, which is movably arranged coaxially with the driving assembly, and the detection rod 144 is located between the at least two clamping jaws 151; a detection assembly 140, which is arranged on the driving assembly and is used to detect the position of the detection rod 144. The coaxial arrangement here means that the central axis of the driving assembly is collinear with the central axis of the detection rod. If the driving assembly and the detection rod are cylindrical, it means that the central axis of the driving assembly and the central axis of the detection rod are collinear; if the driving assembly and the detection rod are non-cylindrical, it means that a straight line perpendicular to the cross section of the driving assembly and passing through the geometric center of its cross section is collinear with a straight line perpendicular to the cross section of the detection rod and passing through the geometric center of its cross section.

[0032] By using the nail insertion device, during use, the driving component can be controlled to drive the clamping jaws 151 to clamp the plastic nail. After the nail insertion is completed, the driving component can be controlled to open the clamping jaws 151. At this time, the position of the detection rod 144 detected by the detection unit can be used to determine whether the nail insertion is successful. Compared with the prior art, there is no need to switch workstations from nail insertion to detection, which effectively saves the time required for the entire nail insertion process and improves the nail insertion efficiency.

[0033] like Figure 2 As shown, at least two clamping jaws 151 are arranged around the axial direction of the driving assembly, and the clamping jaws 151 enclose an area, and the detection rod 144 is located in the area.

[0034] like Figure 5 As shown, the nail insertion device also includes a spring 146, which is arranged on the detection rod 144. The spring 146 can drive the detection rod 144 to reset; as shown in the figure, a accommodating space for the detection rod 144 is provided on the clamping jaw. When the nail is taken out, the detection rod 144 is lifted up by the glue nail. When the nail is inserted, the clamping jaw 151 opens. At this time, the position of the detection rod 144 is detected by the detection component 140 to determine whether the glue nail is inserted in place.

[0035] The detection assembly 140 includes two detection parts, and the detection parts are used to detect the position of the detection rod 144 .

[0036] Specifically, Figures 1 to 4In the nail insertion device shown, a detection block 143 is fixedly provided on the detection rod 144, and two detection parts are respectively a first slot-type photoelectric 141 and a second slot-type photoelectric 142. The detection block 143 is fixedly provided on the detection rod 144, and the first slot-type photoelectric 141 and the second slot-type photoelectric 142 are staggered in the length direction of the detection rod 144, that is, the first slot-type photoelectric 141 and the second slot-type photoelectric 142 have a position difference in the length direction of the detection rod 144, that is, the setting positions of the two are staggered in the length direction of the detection rod 144, including the situation where the setting positions are partially staggered and also including the situation where they are completely staggered; different states detected by the two detection parts, that is, different states of the rubber nails can be detected, so as to timely judge what process should be taken to deal with the next step.

[0037] In the initial state before the nail is removed, both the first slot-shaped photoelectric 141 and the second slot-shaped photoelectric 142 fail to sense the detection block 143 , and at this time the detection block 143 is located below the first slot-shaped photoelectric 141 and the second slot-shaped photoelectric 142 .

[0038] When removing the nail, the clamp 151 opens, the nail insertion mechanism drops to a certain position, and the clamp 151 closes. During this process, the rubber nail presses against the detection rod, thereby pushing the detection rod 144 up. Only the second slot-type photoelectric 142 detects the detection block 143. At this time, the nail removal is normal, and then the nail insertion action is performed.

[0039] Specifically, the first slot-type photoelectric 141 and the second slot-type photoelectric 142 partially overlap in the up and down directions, that is, the setting positions are partially staggered; after the nail insertion action is executed, the clamp 151 is loosened, and in the absence of resistance, the detection rod 144 is reset under the drive of the spring 146, and the first slot-type photoelectric 141 and the second slot-type photoelectric 142 can sense three states, namely: State 1, the detection rod 144 has been reset, and the first slot-type photoelectric 141 and the second slot-type photoelectric 142 have not sensed the detection block 143; State 2, the detection rod 144 has not been reset, the first slot-type photoelectric 141 has not sensed the detection block 143, and the second slot-type photoelectric 142 has sensed the detection block 143; State 3, the detection rod 144 is further lifted, and the first slot-type photoelectric 141 and the second slot-type photoelectric 142 have both sensed the detection block 143.

[0040] Among the above three states, state one indicates that no glue nail has been inserted into the injection hole; state two indicates that the nail is inserted normally; state three indicates that the glue nail is not fully inserted into the injection port. At this time, the driving component can be immediately controlled to drive the clamping jaws 151 to clamp the glue nail, remove the glue nail, and reinsert a new glue nail to avoid the glue nail that is not fully inserted affecting subsequent production.

[0041] like Figures 1 to 4As shown, in the first nail insertion device of this embodiment, the first slot-type photoelectric 141 and the second slot-type photoelectric 142 are arranged on the side of the driving component close to the clamping jaw 151, and the detection rod 144 is provided with a horizontally extending extension rod, which passes through the gap between the clamping jaw 151 and the driving component, and the detection block 143 is arranged on the extension rod. Specifically, a detection frame 145 is arranged at the lower end of the driving component, and the detection rod 144 is arranged in the detection frame 145 and can slide up and down along the detection frame 145. The upper end of the detection rod 144 is connected to an extension rod, which extends outward from the inside of the detection frame 145 in a horizontal direction, and the detection block 143 and the detection rod 144 are connected to the two ends of the extension rod; while meeting the requirements of the two slot-type photoelectric detections, it avoids interference between the clamping jaw 151 and the detection rod 144, which affects the two processes of nail insertion and detection.

[0042] Specifically, Figure 1 As shown, the first nail insertion device of this embodiment also includes a base frame 120, on which a rotating cylinder 100 is arranged, and the rotating cylinder 100 is connected to a driving assembly through a coupling 110, and the driving assembly includes a clamping cylinder 130; during the nail insertion process, the rotating cylinder 100 can drive the clamping cylinder 130 to rotate, so that the clamping claw 151 drives the rubber nail to rotate and insert into the injection hole; of course, other power sources such as motors and hydraulic motors can also be used to drive the rotating cylinder 100, and the driving assembly can also use other components such as motors and hydraulic power sources to drive multiple clamping claws 151 to clamp.

[0043] Figure 5 , Figure 6 The second nail insertion device of this embodiment is shown, the driving component includes a clamping cylinder 130, the center of the clamping cylinder 130 is provided with a through hole, the detection rod 144 is arranged in the through hole, the two detection parts are respectively a first photoelectric 147 and a second photoelectric 148, the first photoelectric 147 and the second photoelectric 148 are both arranged on the side of the clamping cylinder 130 away from the clamping claw 151, and the detection rod 144 passes through the clamping cylinder 130; wherein, when the driving component drives the clamping claw 151 to open, the two groups of photoelectric optic fibers can detect different states of the position of the detection rod 144, thereby judging the state of the nail insertion.

[0044] In the initial state before the nail is removed, the first and second photoelectric pairs 147 and 148 are both unable to sense the detection rod 144. At this time, the detection rod 144 is located below the first and second photoelectric pairs 147 and 148.

[0045] When removing the nail, the clamp 151 opens, the nail insertion mechanism drops to a certain position, and the clamp 151 closes. During this process, the rubber nail presses against the detection rod, thereby pushing the detection rod 144 up. Only the first photoelectric sensor 147 senses the detection rod 144. At this time, the nail removal is normal, and then the nail insertion action is performed.

[0046] Specifically, Figure 6 As shown, the first pair of photoelectric devices 147 and the second pair of photoelectric devices 148 are staggered in the length direction of the detection rod 144, that is, the first pair of photoelectric devices 147 and the second pair of photoelectric devices 148 have a position difference in the length direction of the detection rod 144, that is, the setting positions of the two are staggered in the length direction of the detection rod 144, including the situation where the setting positions are partially staggered, and also including the situation where the setting positions are completely staggered; in this scheme, the first pair of photoelectric devices 147 and the second pair of photoelectric devices 148 partially overlap in the up and down directions, that is, the setting positions are partially staggered, after the nail insertion action is performed, when the clamping claw 151 is released, in the absence of resistance, the detection rod 144 is reset under the drive of the spring 146, and the two pair of photoelectric devices have the following three states: state one, the detection rod 144 It has been reset, and both the first pair of photoelectric sensors 147 and the second pair of photoelectric sensors 148 do not sense the detection rod 144; State two, the detection rod 144 has not been reset, the detection rod 144 is not sensed by the first pair of photoelectric sensors 147, and the second pair of photoelectric sensors 148 does not detect the detection rod 144; State three, the detection rod 144 is further lifted, and both the first pair of photoelectric sensors 147 and the second pair of photoelectric sensors 148 detect the detection rod 144; Here, State one indicates that the injection hole has not been nailed, State two indicates that the injection hole has been nailed in place, and State three indicates that the injection hole has not been nailed in place, and the glue nail has not been fully inserted into the injection hole; when the state is detected, the drive assembly can be immediately controlled to control the clamping jaws 151 to clamp the glue nail, the glue nail can be pulled out and thrown into the waste box, and the nail can be reinserted.

[0047] Specifically, Figure 5 As shown, the second nail insertion device of this embodiment also includes an adapter 160, and the clamping cylinder 130 is arranged on the adapter 160; wherein, the adapter 160 is used to connect with the rotation power source to facilitate driving the rubber nail to rotate and insert into the injection hole.
