Description

Technical Field

[0001] The utility model belongs to the technical field of expansion screw assembly, and particularly relates to a sleeve direction detection and correction device and an expansion screw assembly machine. Background Art

[0002] The structure of the existing expansion screw is as follows Figure 1 As shown, the expansion screw consists of a screw rod ( Figure 1 a) in the sleeve ( Figure 1 b) Flat gasket ( Figure 1 c), spring meson ( Figure 1 d) and nuts ( Figure 1 e) in the figure. Since the through hole on the sleeve needs to be located on the side of the screw away from the threaded end, the sleeve needs to be sleeved outside the screw in a specific orientation during the assembly process of the expansion screw. Since the prior art detects whether the orientation of the sleeve is correct by manual identification or by using a visual identification device, the prior art has the problems of high labor intensity and low detection efficiency due to the need to detect whether the orientation of the sleeve is correct by manual identification, and high production cost of the sleeve orientation detection device due to the need to detect whether the orientation of the sleeve is correct by using a visual identification device, and the expensive price of the visual identification device.

[0003] Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0004] The purpose of the present application is to provide a sleeve orientation detection and correction device and an expansion screw assembly machine, which can effectively solve the problems of high labor intensity and low detection efficiency due to the need to manually identify whether the orientation of the sleeve is correct, and high production cost of the sleeve orientation detection device due to the need to use a visual recognition device to identify whether the orientation of the sleeve is correct and the expensive visual recognition device.

[0005] In a first aspect, the present application provides a sleeve orientation detection device, comprising:

[0006] frame;

[0007] A first bracket is installed on the frame, and is provided with a first placement groove for limiting the placement of the sleeve, and a detection groove is provided on the side wall;

[0008] A sleeve rotating assembly is mounted on the frame and is used to drive the sleeve limitedly placed in the first placement slot to rotate;

[0009] The through-beam sensing component is mounted on the first bracket and the sensing end is arranged toward the detection slot, and is used to detect whether the orientation of the sleeve is correct.

[0010] The present application provides a sleeve orientation detection device, which first limits the placement of the sleeve in a first placement slot, then controls the sleeve rotation component to drive the sleeve in the first placement slot to rotate, and uses the radiation sensing component to detect whether the orientation of the sleeve is correct. Since the present application can detect whether the orientation of the sleeve is correct by determining whether the radiation sensing component receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve is correct by manual identification. Since the present application can realize sleeve orientation detection by the cooperation of the radiation sensing component and the sleeve rotation component, and the prices of the radiation sensing component and the sleeve rotation component are much lower than those of the visual recognition device, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device caused by the need to use a visual recognition device to detect whether the orientation of the sleeve is correct and the expensive visual recognition device.

[0011] Furthermore, the sleeve orientation detection device also includes a first limit assembly, which is mounted on the first bracket and is used to limit the placement position of the sleeve.

[0012] Since the first limiting component of the technical solution can limit the placement position of the sleeve, when the sleeve rotating component drives the sleeve to rotate, the first limiting component can limit the rotation position of the sleeve, thereby effectively avoiding the situation where the position of the through hole of the sleeve is offset due to the displacement of the sleeve when the sleeve rotating component drives the sleeve to rotate, thereby effectively avoiding the situation where although the orientation of the sleeve is correct, the through hole of the sleeve cannot face the opposite sensing component, resulting in the opposite sensing component detecting that the orientation of the sleeve is incorrect.

[0013] Further, the first limiting assembly includes a first pneumatic ejector pin, which is mounted on the first bracket and located at the end of the first placement groove, and the first pneumatic ejector pin is used to limit the placement position of the sleeve in the first placement groove.

[0014] Furthermore, an opening is provided on the side wall of the first bracket, and the sleeve rotation assembly includes a driving assembly, a first rotating assembly and a turntable. The driving assembly is installed on the frame, and the driving assembly is connected to the first rotating assembly. The driving assembly is used to drive the first rotating assembly to move toward or away from the first bracket. The first rotating assembly is connected to the turntable, and the side wall of the turntable is opposite to the opening. The first rotating assembly is used to drive the turntable to rotate.

[0015] Furthermore, the radiation sensing component includes a light emitter and a light receiver, which are symmetrically arranged on two side walls of the first bracket, and the light receiver can receive the light emitted by the light emitter through the detection slot.

[0016] Furthermore, the sleeve orientation detection device also includes a sleeve supply assembly, which is installed on the frame, and the output end of the sleeve supply assembly is connected to one end of the first bracket, and the sleeve supply assembly is used to supply the sleeve to the first bracket.

[0017] Since the technical solution can automatically supply the sleeve to the first bracket by providing the sleeve supply assembly, the technical solution can effectively avoid the situation where the labor intensity is high due to the need to manually supply the sleeve to the first bracket.

[0018] In a second aspect, the utility model further provides a sleeve orientation correction device, which comprises:

[0019] frame;

[0020] A first bracket is installed on the frame, and is provided with a first placement groove for limiting the placement of the sleeve, and a detection groove is provided on the side wall;

[0021] A sleeve rotating assembly is mounted on the frame and is used to drive the sleeve limitedly placed in the first placement slot to rotate;

[0022] A beam sensing component is mounted on the first bracket and the sensing end is arranged toward the detection slot, and is used to detect whether the orientation of the sleeve is correct;

[0023] The orientation correction component is installed on the frame, one end of which is directly opposite to the output end of the first bracket and is used for flipping the sleeve with incorrect orientation.

[0024] The present application provides a sleeve orientation correction device, which first limits the sleeve to a position in a first placement slot, then controls the sleeve rotation component to drive the sleeve in the first placement slot to rotate, and uses a radiation sensing component to detect whether the orientation of the sleeve is correct, and finally uses the orientation correction component to correct the sleeve with incorrect orientation. Since the present application can detect whether the orientation of the sleeve is correct by detecting whether the radiation sensing component receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve is correct by manual identification, and since the present application can realize the sleeve orientation correction by the cooperation of the radiation sensing component and the sleeve rotation component The price of the radiation sensing component and the sleeve rotation component is much lower than that of the visual recognition device. Therefore, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device due to the need to use a visual recognition device to detect whether the orientation of the sleeve is correct and the expensive price of the visual recognition device. Moreover, when the sleeve orientation is detected to be incorrect, the present application can correct the orientation of the sleeve by driving the sleeve to rotate 180° using the orientation correction component. Therefore, the present application can effectively avoid the problem of high labor intensity and low correction efficiency due to the need to manually correct the incorrectly oriented sleeve, thereby effectively improving the efficiency of sleeve-mounting the sleeve with the correct orientation outside the screw.

[0025] Furthermore, the orientation correction assembly includes a second rotating assembly, a second limiting assembly and a second bracket, the second bracket is provided with a second placement groove for placing the sleeve, the second rotating assembly is installed on the frame, one end of the second bracket is opposite to the output end of the first bracket, the second limiting assembly is installed on the second bracket, the second limiting assembly is used to limit the placement position of the sleeve with incorrect orientation in the second placement groove, the second rotating assembly is connected to the second bracket, and the second rotating assembly is used to drive the sleeve with incorrect orientation to rotate 180°.

[0026] Since the orientation correction component of the technical solution includes a second rotating component, a second limiting component and a second bracket, and one end of the second bracket is opposite to the output end of the first bracket, after the radiation sensing component completes the detection of the sleeve orientation, the sleeve of the technical solution moves from the first bracket to the second bracket, and when the second rotating component drives the second bracket to rotate, the radiation sensing component can detect the sleeve orientation of the next sleeve, that is, the technical solution can further improve the efficiency of sleeve orientation detection.

[0027] Further, the second limiting assembly includes a third pneumatic ejector pin and a fourth pneumatic ejector pin, and the third pneumatic ejector pin and the fourth pneumatic ejector pin are both mounted on the second bracket and are respectively located on both sides of the sleeve that is not facing correctly.

[0028] In a third aspect, the utility model further provides an expansion screw assembly machine, which includes a sleeve orientation correction device as provided in the second aspect above.

[0029] The present application provides an expansion screw assembly machine, including a sleeve orientation correction device, which first limits the sleeve to a position in a first placement slot, then controls the sleeve rotation component to drive the sleeve in the first placement slot to rotate, and uses a radiation sensing component to detect whether the orientation of the sleeve is correct, and finally uses the orientation correction component to correct the sleeve with an incorrect orientation. Since the present application can detect whether the orientation of the sleeve is correct by detecting whether the radiation sensing component receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve is correct by manual identification, and since the present application can detect whether the orientation of the sleeve is correct by a radiation sensing component and a sleeve rotation component The rotating assembly cooperates to realize the orientation detection of the sleeve, and the price of the radiation sensing assembly and the sleeve rotating assembly is much lower than that of the visual recognition device. Therefore, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device due to the need to use a visual recognition device to detect whether the orientation of the sleeve is correct and the expensive visual recognition device. Moreover, when the sleeve orientation is detected to be incorrect, the present application can correct the orientation of the sleeve by driving the sleeve to rotate 180° using the orientation correction assembly. Therefore, the present application can effectively avoid the problem of high labor intensity and low correction efficiency due to the need to manually correct the incorrectly oriented sleeve, thereby effectively improving the efficiency of installing the sleeve with the correct orientation outside the screw.

[0030] As can be seen from the above, the utility model provides a sleeve orientation detection and correction device and an expansion screw assembly machine, which first limits the sleeve to a position in the first placement slot, then controls the sleeve rotation component to drive the sleeve in the first placement slot to rotate, and uses the radiation sensing component to detect whether the orientation of the sleeve is correct. Since the present application can detect whether the orientation of the sleeve is correct by detecting whether the radiation sensing component receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve is correct by manual identification. Since the present application can realize the orientation detection of the sleeve by the cooperation of the radiation sensing component and the sleeve rotation component, and the prices of the radiation sensing component and the sleeve rotation component are much lower than those of the visual recognition device, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device caused by the need to use a visual recognition device to detect whether the orientation of the sleeve is correct and the expensive visual recognition device.

DETAILED DESCRIPTION

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0039] First, as Figure 2 , Figure 3 and Figure 5 As shown, the present application provides a sleeve orientation detection device, which includes:

[0040] Rack 1;

[0041] The first bracket 2 is mounted on the frame 1, and is provided with a first placement groove for limiting the placement of the sleeve 6, and a detection groove 10 is provided on the side wall thereof;

[0042] The sleeve rotating assembly 3 is mounted on the frame 1 and is used to drive the sleeve 6 limitedly placed in the first placement groove to rotate;

[0043] The through-beam sensing component 4 is mounted on the first bracket 2 and the sensing end is arranged toward the detection slot 10, and is used to detect whether the orientation of the sleeve 6 is correct.

[0044] In this embodiment, if the orientation of the sleeve 6 is correct, the distance between the end of the sleeve 6 near its through hole and the output end of the first bracket 2 is smaller than the distance between the other end of the sleeve 6 and the output end of the first bracket 2. If the orientation of the sleeve 6 is incorrect, the distance between the end of the sleeve 6 near its through hole and the output end of the first bracket 2 is larger than the distance between the other end of the sleeve 6 and the output end of the first bracket 2. It should be understood that those skilled in the art may also believe that when the orientation of the sleeve 6 is correct, the distance between the end of the sleeve 6 near its through hole and the output end of the first bracket 2 is larger than the distance between the other end of the sleeve 6 and the output end of the first bracket 2. The frame 1 of this embodiment can support the first bracket 2, the sleeve rotating assembly 3, the radiation sensing assembly 4 and the sleeve 6. The first bracket 2 of this embodiment can be horizontally arranged on the frame 1, and the first bracket 2 of this embodiment can also be arranged on the frame 1 tilted downward. A first placement groove for limiting the placement of the sleeve 6 is provided in the first bracket 2, and the first placement groove can preferably only place one sleeve 6. A detection groove 10 is provided on the side wall of the first bracket 2 of this embodiment. This embodiment can manually place the sleeve 6 in the first bracket 2, and this embodiment can also place the sleeve 6 in the first bracket 2 by automatic loading (for example, using a robot to place the sleeve 6 in the first bracket 2 or connecting the input end of the first bracket 2 with the output end of the sleeve production component). The sleeve rotating assembly 3 of this embodiment can be an assembly such as a motor or a synchronous belt that can drive the sleeve 6 limitedly placed in the first bracket 2 to rotate. The sleeve rotating assembly 3 of this embodiment is installed on the frame 1. The sleeve rotating assembly 3 of this embodiment can drive the sleeve 6 limitedly placed in the first bracket 2 to rotate by driving the first bracket 2 to rotate. The sleeve rotating assembly 3 of this embodiment can also drive the sleeve 6 limitedly placed in the first placement groove to rotate by only driving the sleeve 6 to rotate (that is, driving the sleeve 6 to rotate relative to the first bracket 2).The through-beam sensing component 4 of this embodiment is installed on the first bracket 2 and the sensing end is arranged toward the detection slot 10. The through-beam sensing component 4 can be a component such as a through-beam sensor, a photoelectric sensor or a photoelectric switch that uses light to detect whether the orientation of the sleeve 6 is correct. Specifically, the through-beam sensing component 4 of this embodiment is installed on the side of the first bracket 2 close to its output end. The minimum distance from the detection slot 10 to the output end of the first bracket 2 is less than the minimum distance from the detection slot 10 to the input end of the first bracket 2. The principle of the through-beam sensing component 4 of this embodiment to detect whether the orientation of the sleeve 6 is correct is that when the orientation of the sleeve 6 is correct, the distance between the end of the sleeve 6 close to its through hole and the output end of the first bracket 2 is less than the distance between the end of the sleeve 6 and the output end of the first bracket 2. The other end is at a distance from the output end of the first bracket 2, and the through-radiation sensing component 4 of this embodiment is installed on a side of the first bracket 2 close to its output end and the sensing end is arranged toward the detection slot 10. Therefore, if the orientation of the sleeve 6 is correct, then under the driving action of the sleeve rotating component 3, the through hole of the sleeve 6 is exposed in the detection slot 10, and the light emitted by the through-radiation sensing component 4 can pass through the through hole through the detection slot 10. If the orientation of the sleeve 6 is incorrect, the through hole of the sleeve 6 cannot be exposed in the detection slot 10 under the driving action of the sleeve rotating component 3, and the light emitted by the through-radiation sensing component 4 cannot pass through the through hole through the detection slot 10. Therefore, this embodiment can use the through-radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct.

[0045] The present application provides a sleeve orientation detection device, which first limits the placement of the sleeve 6 in the first placement slot, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement slot to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct. Since the present application can detect whether the orientation of the sleeve 6 is correct by detecting whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification. Since the present application can realize the orientation detection of the sleeve 6 by the cooperation of the radiation sensing component 4 and the sleeve rotation component 3, and the prices of the radiation sensing component 4 and the sleeve rotation component 3 are much lower than those of the visual recognition device, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device caused by the need to use a visual recognition device to detect whether the orientation of the sleeve 6 is correct and the expensive visual recognition device.

[0046] In some embodiments, the sleeve orientation detection device further includes a first position-limiting component 5, which is mounted on the first bracket 2 and is used to limit the placement position of the sleeve 6 in the first placement groove. The first position-limiting component 5 of this embodiment is mounted on the first bracket 2, and the first position-limiting component 5 of this embodiment can be a component such as an electric telescopic rod or an electric telescopic block that can limit the placement position of the sleeve 6. It should be understood that the first position-limiting component 5 of this embodiment is only used to limit the placement position of the sleeve 6, and it does not hinder the sleeve rotation component 3 from driving the sleeve 6 to rotate. Since the first position-limiting component 5 of this embodiment can limit the placement position of the sleeve 6, when the sleeve rotating component 3 drives the sleeve 6 to rotate, the first position-limiting component 5 can limit the rotation position of the sleeve 6, thereby effectively avoiding the situation that the position of the through hole of the sleeve 6 is offset due to the displacement of the sleeve 6 when the sleeve rotating component 3 drives the sleeve 6 to rotate, thereby effectively avoiding the situation that although the orientation of the sleeve 6 is correct, the through hole of the sleeve 6 cannot face the opposite sensing component 4, resulting in the opposite sensing component 4 detecting that the orientation of the sleeve 6 is incorrect. In addition, if the first bracket 2 is tilted downward on the frame 1, this embodiment can discharge the sleeves 6 one by one through the first position-limiting component 5 to perform continuity detection on the sleeves 6.

[0047] In some embodiments, the first position-limiting assembly includes a first pneumatic ejector pin 51, which is mounted on the first bracket 2 and located at the end of the first placement slot, and the first pneumatic ejector pin 51 is used to limit the placement position of the sleeve 6 in the first placement slot. Preferably, the first position-limiting assembly of this embodiment also includes a second pneumatic ejector pin 52, which is mounted on the first bracket 2, and the second pneumatic ejector pin 52 is used to limit the position of other sleeves 6 other than the sleeve 6 located at the end of the first placement slot, so that only one sleeve 6 is located at the end of the first placement slot at the same time. More preferably, the second pneumatic ejector pin 52 and the radiation sensing assembly 4 are both positionally adjustable on the first bracket 2, so that the sleeve orientation detection device can be applied to sleeves 6 of different lengths, thereby effectively improving the versatility of the sleeve orientation detection device.

[0048] In some embodiments, the side wall of the first bracket 2 is further provided with an opening 7, and the sleeve rotating assembly 3 includes a driving assembly 31, a first rotating assembly 32 and a turntable 33. The driving assembly 31 is installed on the frame 1, and the driving assembly 31 is connected to the first rotating assembly 32. The driving assembly 31 is used to drive the first rotating assembly 32 to move toward or away from the first bracket 2. The first rotating assembly 32 is connected to the turntable 33, and the side wall of the turntable 33 is directly opposite to the opening 7. The first rotating assembly 32 is used to drive the turntable 33 to rotate. The driving assembly 31 of this embodiment can be a component such as a cylinder, an oil cylinder or a hydraulic cylinder that can drive the first rotating assembly 32 to move toward or away from the first bracket 2. The driving assembly 31 is preferably a cylinder, and the first rotating assembly 32 of this embodiment is preferably a servo motor. Specifically, the working process of the sleeve rotating assembly 3 of this embodiment driving the sleeve 6 to rotate is as follows: the driving assembly 31 drives the first rotating assembly 32 to move toward the first bracket 2 so that the turntable 33 passes through the opening 7 and conflicts with the sleeve 6; the first rotating assembly 32 drives the turntable 33 to rotate to drive the sleeve 6 to rotate. It should be understood that when the radiation sensing component 4 completes the orientation detection of the sleeve 6 , this embodiment controls the sleeve rotating component 3 to stop driving the sleeve 6 to rotate, and controls the driving component 31 to drive the first rotating component 32 to move away from the first bracket 2 .

[0049] In some embodiments, the radiation sensing component 4 includes a light emitter 41 and a light receiver 42, which are symmetrically arranged on two side walls of the first bracket 2, and the light receiver 42 can receive the light emitted by the light emitter 41 through the detection slot 10. Specifically, if the through hole of the sleeve 6 is exposed in the detection slot 10, the light receiver 42 receives the light emitted by the light emitter 41.

[0050] In some embodiments, the sleeve orientation detection device further includes a sleeve supply assembly 8, which is mounted on the frame 1, and the output end of the sleeve supply assembly 8 is connected to one end of the first bracket 2, and the sleeve supply assembly 8 is used to supply the sleeve 6 to the first bracket 2. The sleeve supply assembly 8 of this embodiment is preferably a vibration plate, and since this embodiment can automatically supply the sleeve 6 to the first bracket 2 by setting the sleeve supply assembly 8, this embodiment can effectively avoid the situation where the labor intensity is high due to the need to manually supply the sleeve 6 to the first bracket 2.

[0051] As can be seen from the above, the present application provides a sleeve orientation detection device, which first limits the placement of the sleeve 6 in the first placement slot, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement slot to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct. Since the present application can detect whether the orientation of the sleeve 6 is correct by detecting whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problems of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification. Since the present application can realize the orientation detection of the sleeve 6 by the cooperation of the radiation sensing component 4 and the sleeve rotation component 3, and the prices of the radiation sensing component 4 and the sleeve rotation component 3 are much lower than those of the visual recognition device, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device caused by the need to use a visual recognition device to detect whether the orientation of the sleeve 6 is correct and the expensive visual recognition device.

[0052] Second, as Figure 4 As shown, the utility model also provides a sleeve orientation correction device, which includes:

[0053] Rack 1;

[0054] The first bracket 2 is mounted on the frame 1, and is provided with a first placement groove for limiting the placement of the sleeve 6, and a detection groove 10 is provided on the side wall thereof;

[0055] The sleeve rotating assembly 3 is mounted on the frame 1 and is used to drive the sleeve 6 limitedly placed in the first placement groove to rotate;

[0056] The beam sensing component 4 is mounted on the first bracket 2 and the sensing end is arranged toward the detection slot 10, and is used to detect whether the orientation of the sleeve 6 is correct;

[0057] The orientation correction component 9 is installed on the frame 1, with one end thereof facing the output end of the first bracket 2, and is used for flipping the sleeve 6 with incorrect orientation.

[0058] The embodiment of the present application provides a sleeve orientation correction device, which is equivalent to including the sleeve orientation detection device and the orientation correction component 9 provided in the first aspect above. The orientation correction component 9 of this embodiment is installed on the frame 1, and the orientation correction component 9 of this embodiment can be a component such as a motor or a synchronous belt that can flip the sleeve 6 with an incorrect orientation. It should be understood that after the orientation correction component 9 flips the sleeve 6 with an incorrect orientation, the orientation of the sleeve 6 is correct, that is, the sleeve 6 flipped by the orientation correction component can be directly sleeved on the screw.

[0059] The present application provides a sleeve orientation correction device, which first limits the placement of the sleeve 6 in the first placement slot, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement slot to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct, and finally uses the orientation correction component 9 to correct the sleeve 6 with incorrect orientation. Since the present application can detect whether the orientation of the sleeve 6 is correct by detecting whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problem of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification, and since the present application can be achieved through the cooperation of the radiation sensing component 4 and the sleeve rotation component 3 The direction detection of the sleeve 6, and the price of the radiation sensing component 4 and the sleeve rotation component 3 is much lower than that of the visual recognition device. Therefore, the present application can effectively solve the problem of high production cost of the sleeve direction detection device due to the need to use a visual recognition device to detect whether the direction of the sleeve 6 is correct and the expensive price of the visual recognition device. Moreover, when the incorrect orientation of the sleeve 6 is detected, the present application can correct the orientation of the sleeve 6 by driving the sleeve 6 to rotate 180° using the orientation correction component 9. Therefore, the present application can effectively avoid the problem of high labor intensity and low correction efficiency due to the need to manually correct the incorrectly oriented sleeve 6, thereby effectively improving the efficiency of sleeveing ​​the correctly oriented sleeve 6 outside the screw.

[0060] In some embodiments, the orientation correction component 9 includes a second rotating component 91, a second limiting component 92 and a second bracket 93, the second bracket 93 is provided with a second placement slot for placing the sleeve 6, the second rotating component 91 is mounted on the frame 1, one end of the second bracket 93 is directly opposite to the output end of the first bracket 2, the second limiting component 92 is mounted on the second bracket 93, the second limiting component 92 is used to limit the placement position of the sleeve 6 with incorrect orientation in the second placement slot, the second rotating component 91 is connected to the second bracket 93, and the second rotating component 91 is used to drive the sleeve 6 with incorrect orientation to rotate 180°. The second rotating component 91 of this embodiment is preferably a motor, and the second limiting component 92 can prevent the sleeve 6 with incorrect orientation from sliding out of the second bracket 93 when the second rotating component 91 drives the second bracket 93 to rotate. Since the orientation correction component 9 of this embodiment includes a second rotating component 91, a second limiting component 92 and a second bracket 93, and one end of the second bracket 93 is opposite to the output end of the first bracket 2, after the radiation sensing component 4 completes the detection of the orientation of the sleeve 6, the sleeve 6 of this embodiment moves from the first bracket 2 to the second bracket 93, and when the second rotating component 91 drives the second bracket 93 to rotate, the radiation sensing component 4 can detect the orientation of the next sleeve 6, that is, this embodiment can further improve the efficiency of sleeve orientation detection of the sleeve 6. It should be understood that the first bracket 2 and the second bracket 93 of this embodiment are preferably arranged on the frame 1 with an inclination downward, so after the radiation sensing component 4 completes the detection of the orientation of the sleeve 6, the first limiting component 5 releases the restriction on the placement position of the sleeve 6 that has completed the orientation detection, so that the sleeve 6 slides from the first bracket 2 to the second bracket 93 under the action of gravity.

[0061] In some embodiments, the second limiting assembly 92 includes a third pneumatic ejector pin 921 and a fourth pneumatic ejector pin 922 , and the third pneumatic ejector pin 921 and the fourth pneumatic ejector pin 922 are both mounted on the second bracket 93 and are respectively located on both sides of the sleeve 6 that is not facing correctly.

[0062] As can be seen from the above, the present application provides an orientation correction device, which first limits the placement of the sleeve 6 in the first placement slot, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement slot to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct, and finally uses the orientation correction component 9 to correct the sleeve 6 with incorrect orientation. Since the present application can detect whether the orientation of the sleeve 6 is correct by detecting whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problem of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification, and since the present application can be implemented by the cooperation of the radiation sensing component 4 and the sleeve rotation component 3 The orientation of the sleeve 6 is now detected, and the prices of the radiation sensing component 4 and the sleeve rotation component 3 are much lower than those of the visual recognition device. Therefore, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device due to the need to use a visual recognition device to detect whether the orientation of the sleeve 6 is correct and the expensive price of the visual recognition device. Moreover, when it is detected that the orientation of the sleeve 6 is incorrect, the present application can correct the orientation of the sleeve 6 by driving the sleeve 6 to rotate 180° using the orientation correction component 9. Therefore, the present application can effectively avoid the problem of high labor intensity and low correction efficiency due to the need to manually correct the incorrectly oriented sleeve 6, thereby effectively improving the efficiency of sleeveing ​​the correctly oriented sleeve 6 outside the screw.

[0064] An embodiment of the present application also provides an expansion screw assembly machine, which includes a sleeve orientation correction device as provided in the second aspect above. The principle of the expansion screw assembly machine of this embodiment is the same as the principle of the sleeve orientation correction device provided in the second aspect above, and will not be discussed in detail here.

[0065] As can be seen from the above, the expansion screw assembly machine provided by the present application includes a sleeve orientation correction device, which first limits the position of the sleeve 6 and places it in the first placement groove, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement groove to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct, and finally uses the orientation correction component 9 to correct the sleeve 6 with incorrect orientation. Since the present application can detect whether the orientation of the sleeve 6 is correct by detecting whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problem of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification, and since the present application can detect whether the orientation of the sleeve 6 is correct by the radiation sensing component 4 and The sleeve rotation component 3 cooperates to realize the orientation detection of the sleeve 6, and the price of the radiation sensing component 4 and the sleeve rotation component 3 is much lower than that of the visual recognition device. Therefore, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device due to the need to use a visual recognition device to detect whether the orientation of the sleeve 6 is correct and the expensive visual recognition device. Moreover, when it is detected that the orientation of the sleeve 6 is incorrect, the present application can correct the orientation of the sleeve 6 by driving the sleeve 6 to rotate 180° using the orientation correction component 9. Therefore, the present application can effectively avoid the problem of high labor intensity and low correction efficiency due to the need to manually correct the sleeve 6 with incorrect orientation, thereby effectively improving the efficiency of sleeve 6 with correct orientation being mounted outside the screw.

[0066] As can be seen from the above, the utility model provides a sleeve orientation detection and correction device and an expansion screw assembly machine, which first limits the sleeve 6 to be placed in the first placement slot, then controls the sleeve rotation component 3 to drive the sleeve 6 in the first placement slot to rotate, and uses the radiation sensing component 4 to detect whether the orientation of the sleeve 6 is correct. Since the present application can detect whether the orientation of the sleeve 6 is correct by whether the radiation sensing component 4 receives the light emitted by it, the present application does not need to detect whether the orientation of the sleeve 6 is correct by manual identification, thereby effectively solving the problem of high labor intensity and low detection efficiency caused by the need to detect whether the orientation of the sleeve 6 is correct by manual identification. Since the present application can realize the orientation detection of the sleeve 6 by the cooperation of the radiation sensing component 4 and the sleeve rotation component 3, and the price of the radiation sensing component 4 and the sleeve rotation component 3 is much lower than that of the visual recognition device, the present application can effectively solve the problem of high production cost of the sleeve orientation detection device caused by the need to use a visual recognition device to detect whether the orientation of the sleeve 6 is correct and the expensive visual recognition device.
