[0030] See also Figure 1 and Figure 2In one embodiment of the present application, a clamping device 10 is provided. The clamping device 10 includes a base 101, a carrier 102, a clamping member 103, a blocking member 104, a position detector 105, and a controller (not shown in the figure). The carrier 102 is connected to the base 101, and the carrier 102 has a bearing surface 1021 for bearing a cut piece. The clamping member 103 is connected to the base 101, and a clamping channel is formed between the clamping member 103 and the bearing surface 1021, and the clamping member 103 is used to clamp the cut piece on the bearing surface 1021. The blocking member 104 protrudes from the bearing surface 1021 to block the cut piece from passing through the clamping channel. The position detector 105 is connected to the carrier 102 and is located between the blocking member 104 and the clamping member 103 to detect whether the cut piece passes through the clamping channel. The clamping member 103 and the position detector 105 are electrically connected to the controller respectively. The controller is used to receive the position information of the cut piece detected by the position detector 105 and control the movement of the clamping member 103 according to the position information.

[0031] In the clamping device 10 of this embodiment, the position of the cut piece can be detected by the position detector 105. When the position detector 105 detects that the cut piece passes through the clamping channel, the position information of the cut piece can be transmitted to the controller, and then the controller controls the clamping member 103 to clamp the cut piece in time. At the same time, when the cut piece passes through the clamping channel, the blocking member 104 can block the cut piece, reducing the probability of excessive displacement of the cut piece, so that the accuracy of the fixed position of the cut piece can be improved.

[0032] It can be understood that the clamping device 10 of this embodiment can be used to clamp strip-shaped pieces, collar pieces, sleeve pieces, etc. The shape of the pieces can be strip-shaped, arc-shaped, etc.

[0033] In some embodiments, the blocking member 104 includes a first side position 1041 and a second side position 1042. The first side position 1041 and the second side position 1042 both protrude from the bearing surface 1021, and the first side position 1041 and the second side position 1042 are spaced apart from each other. The first side position 1041 and the second side position 1042 are respectively used to abut different parts of the cut piece, thereby blocking the cut piece. By setting the first side position 1041 and the second side position 1042, two spaced parts on the same side of the cut piece can be abutted, thereby reducing the probability of the cut piece being tilted, and further improving the accuracy of fixing the position of the cut piece. It is understandable that the spacing distance between the first side position 1041 and the second side position 1042 can be set according to the size of the cut piece.

[0034] In some embodiments, the position detector 105 includes a first sub-position detector 1051 and a second sub-position detector 1052 respectively connected to the first side position 1041 and the second side position 1042, and the first sub-position detector 1051 and the second sub-position detector 1052 are respectively used to detect whether different parts of the cut piece pass through the clamping channel. It can be understood that the first sub-position detector 1051 and the second sub-position detector 1052 are respectively electrically connected to the controller, so that the positions of different parts of the cut piece can be detected, and the position information of different parts of the cut piece can be transmitted to the controller. Optionally, when the first sub-position detector 1051 and the second sub-position detector 1052 detect the cut piece at the same time, it indicates that the cut piece is not tilted. At this time, the controller controls the clamping member 103 to clamp the cut piece, so that the cut piece can be clamped just at a position where no tilt occurs, which is conducive to further improving the accuracy of the cut piece position fixation.

[0035] In some embodiments, the carrier 102 further has a back surface 1022 opposite to the carrier surface 1021, and a first optical path through hole 1023 and a second optical path through hole 1024 are provided on the carrier 102. The first sub-position detector 1051 includes a first photoelectric sensor 10511 and a first reflector 10512, the first reflector 10512 is located on the first side position 1041, the first photoelectric sensor 10511 is located on the back surface 1022 of the carrier 102, the light outlet of the first photoelectric sensor 10511 is arranged opposite to the first reflector 10512, and the light emitted by the first photoelectric sensor 10511 can pass through the first optical path through hole 1023 to reach the first reflector 10512. The second sub-position detector 1052 includes a second photoelectric sensor 10521 and a second reflector 10522. The second reflector 10522 is located on the second side 1042. The second photoelectric sensor 10521 is located on the back side 1022. The light outlet of the second photoelectric sensor 10521 is arranged opposite to the second reflector 10522. The light emitted by the second photoelectric sensor 10521 can pass through the second light path through hole 1024 to reach the second reflector 10522. The first sub-position detector 1051 includes a first photoelectric sensor 10511 and a first reflector 10512. The position of the cut piece can be detected more accurately through the cooperation of the first photoelectric sensor 10511 and the first reflector 10512. The second sub-position detector 1052 includes a second photoelectric sensor 10521 and a second reflector 10522. The position of the cut piece can be detected more accurately through the cooperation of the second photoelectric sensor 10521 and the second reflector 10522.

[0036] In some embodiments, the first reflector 10512 is fixedly connected to the first side position 1041 , and the second reflector 10522 is fixedly connected to the second side position 1042 .

[0037] In some embodiments, the first reflective element 10512 and the second reflective element 10522 are both reflective paper. Further, in order to facilitate the installation of the reflective paper, a mounting position can be extended from one end of the first side position 1041 away from the bearing surface 1021 to install the reflective paper, and a mounting position can also be extended from one end of the second side position 1042 away from the bearing surface 1021 to install the reflective paper.

[0038] In some embodiments, the clamping device 10 further includes a slide rail 106 and a slider 107. The slide rail 106 is connected to the back side 1022 of the carrier 102, the slider 107 is slidably connected to the slide rail 106, the second photoelectric sensor 10521 is fixed on the slider 107, and the second light path through hole 1024 is a bar-shaped through hole. At this time, the position of the second photoelectric sensor 10521 can be adjusted by sliding the slider 107 along the slide rail 106, and can be used to detect the position information of the cut pieces of different lengths. It can be understood that the second light path through hole 1024 is a bar-shaped through hole, so that the light emitted by the second photoelectric sensor 10521 can pass through the second light path through hole 1024 smoothly when there is no cut piece blocking it during the movement.

[0039] In some embodiments, the first photoelectric sensor 10511 is fixed to the carrying surface 1021. At this time, the distance between the second photoelectric sensor 10521 and the first photoelectric sensor 10511 can be adjusted by sliding the slider 107, so as to more conveniently detect the position information of the cut pieces of different lengths.

[0040] In some embodiments, the clamping device 10 further includes a second driving member (not shown in the figure). The second driving member is connected to the slider 107 to drive the slider 107 to move along the slide rail 106. It is understandable that the second driving member is electrically connected to the controller, and the controller can be used to control the second driving member to drive the slider 107 to move.

[0041] In some embodiments, a guide 108 is provided on the slider 107, a guide channel 1025 is provided on the carrier 102, the guide 108 extends from the slider 107 and passes through the guide channel 1025, the second photoelectric sensor 10521 and the second reflector 10522 are respectively connected to the guide 108, and the second photoelectric sensor 10521 and the second reflector 10522 are respectively located on opposite sides of the carrier 102. At this time, the sliding of the slider 107 can drive the second photoelectric sensor 10521 and the second reflector 10522 to move synchronously, so as to detect the position of the cut piece more accurately and efficiently. Optionally, the guide channel 1025 is parallel to the slide rail 106.

[0042] In some embodiments, the clamping device 10 further includes a limit sensor. The limit sensor is connected to the back side 1022 of the carrier 102 to detect the position information of the slider 107. The limit sensor can detect the position information of the slider 107, and then adjust the position of the slider 107 according to the actual working conditions.

[0043] In some embodiments, the limit sensor includes a first sub-limit sensor 109 and a second sub-limit sensor 110. The first sub-limit sensor 109 and the second sub-limit sensor 110 are respectively located at two ends of the guide channel 1025 to detect the position information of the slider 107.

[0044] In some embodiments, the clamping device 10 further includes a first driving member 111, which is connected to a controller, and the first driving member 111 is also connected to the clamping member 103, and the controller drives the clamping member 103 to move through the first driving member 111. At this time, the controller can receive the position information of the cut piece detected by the position detector 105, and then drive the first driving member 111 to move through the controller, thereby driving the clamping member 103 to move.

[0045] In some embodiments, the first driving member 111 is disposed on the back side 1022 of the carrier 102. Optionally, a hole is provided on the carrier 102 for the driving end of the first driving member 111 to pass through, so that the driving end of the first driving member 111 is connected to the clamping member 103.

[0046] In some embodiments, there are multiple clamping members 103 and multiple first driving members 111, and the multiple first driving members 111 correspond to the multiple clamping members 103 one by one. The multiple clamping members 103 are arranged side by side, and each clamping member 103 is connected to the corresponding first driving member 111. In this case, the multiple first driving members 111 can drive the multiple clamping members 103 to move, so as to clamp the cut piece more stably. Figure 1 and Figure 2 In the clamping device 10 shown, there are two clamping members 103 and two first driving members 111, and the two first driving members 111 respectively drive the corresponding clamping members 103. It is understandable that there may also be three, four, five, etc. clamping members 103.

[0047] It is understood that when using the above-mentioned clamping device 10, the length of the cut piece can be first input into the controller, and then the distance between the first side position 1041 and the second side position 1042 can be adjusted according to the length of the cut piece. When adjusting the distance between the first side position 1041 and the second side position 1042, the distance between the first photoelectric sensor 10511 and the second photoelectric sensor 10521 is adjusted synchronously. At this time, when the cut piece moves on the carrying surface 1021 of the carrying platform 102, when the first photoelectric sensor 10511 and the second photoelectric sensor 10521 detect the cut piece at the same time, the first driving member 111 is controlled to move by the controller, thereby driving the clamping member 103 to clamp the cut piece. If the first photoelectric sensor 10511 and the second photoelectric sensor 10521 do not detect the cut piece at the same time, the cut piece may not be clamped, and the position of the cut piece is adjusted so that the first photoelectric sensor 10511 and the second photoelectric sensor 10521 detect the cut piece at the same time, so that the cut piece can be clamped in a non-tilted state. At the same time, the first side position 1041 and the second side position 1042 can block different parts of the same side of the cut piece to prevent the cut piece from excessive displacement, thereby making the fixed position of the cut piece more accurate.

[0048] See also Figure 3 In another embodiment of the present application, a sewing device 20 is provided. The sewing device 20 includes a frame 201, a manipulator 202, a sewing piece, and the above-mentioned clamping device 10. The sewing piece is connected to the frame 201, and the two ends of the manipulator 202 are respectively connected to the frame 201 and the base 101. The manipulator 202 is used to transfer the clamping device 10 to the sewing piece, and then sew the clamped cut pieces. In the sewing device 20, the cut pieces can be transferred to the corresponding positions of the sewing piece by the manipulator 202, and then the cut pieces are sewn. Since the position of the cut pieces in the clamping device 10 is accurately fixed, the accuracy of sewing can be improved, and the yield of the product can be improved. Optionally, the sewing machine includes an overlock sewing machine 203 and a sewing machine 204.
