Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber communication, and particularly to an automatic assembly device for MT guide pins. Background Art

[0002] The MT pin socket and the guide pin are key positioning and guiding components in the application of optical modules. At present, manufacturers in the industry all use manual jigs or manual assembly methods to achieve assembly. There are some defects in manual assembly. Firstly, due to the inability to unify the force and position dimensions of the fixture or manual assembly, it is easy to have problems with poor assembly of the guide pins. Secondly, the assembly efficiency of manual or jig assembly is relatively low. Summary of the Invention

[0003] In view of this, the purpose of the embodiments of the present invention is to provide an automatic assembly device for MT guide pins, which can reduce poor assembly and improve efficiency.

[0004] To solve one of the above problems, an automatic assembly device for MT guide pins of the present invention includes a feeding tray, a conveying channel, a press-fitting mechanism, and a station turntable. The conveying channel includes a sorting channel and a linear vibrating channel. The press-fitting mechanism includes a guide pin clamping component and a moving component.

[0005] A sorting sensor and a guide pin screening component are arranged on the sorting channel. When the sorting sensor detects an abnormal guide pin, the guide pin screening component removes the abnormal guide pin from the sorting channel. The abnormal guide pin refers to the guide pin whose assembly groove enters the sorting channel later.

[0006] The sorting channel is arranged in the feeding tray. One end of the linear vibrating channel is connected to the sorting channel, and the other end of the linear vibrating channel is docked with the guide pin clamping component. The guide pin clamping component is connected to the moving component, and the moving component drives the guide pin clamping component to press-fit the assembly groove of the guide pin into the pin socket on the station turntable.

[0007] Optionally, the guide pin clamping component includes a feeding hole and a clamping jaw. The feeding hole and the clamping jaw are at the same height, and the feeding hole is docked with the other end of the linear vibrating channel.

[0008] Optionally, the diameter of the feeding hole is 1-2 times the diameter of the guide pin.

[0009] Optionally, the moving component includes a clamping cylinder and a proximity sensor, and the clamping cylinder is connected to the proximity sensor.

[0010] The clamping cylinder is used to drive the clamping jaw to clamp and fix the guide pin when the proximity sensor detects that the guide pin enters the clamping jaw.

[0011] Optionally, the moving part includes a horizontal Y-axis cylinder and a horizontal X-axis cylinder, both of which are connected to the guide pin clamping part;

[0012] The horizontal Y-axis cylinder is used to drive the guide pin clamping part to move along the Y-axis of the horizontal plane;

[0013] The horizontal X-axis cylinder is used to drive the guide pin clamping part to move along the X-axis of the horizontal plane, and press the guide pin clamped by the guide pin clamping part into the assembly groove of the needle base.

[0014] Optionally, the device further includes a guide pin baffle and a lifting device. The lifting device is used to drive the guide pin baffle to move to the other end of the linear vibrating chute to block the guide pin conveying groove of the linear vibrating chute when the guide pin clamping part moves towards the needle base.

[0015] Optionally, the lifting device is further used to drive the guide pin baffle to disengage from the guide pin conveying groove of the linear vibrating chute after the guide pin clamping part presses the assembly groove of the guide pin into the needle base on the station turntable.

[0016] Optionally, the diameter of the guide pin conveying groove on the linear vibrating chute is equal to the diameter of the guide pin.

[0017] Optionally, the sorting sensor includes an optical fiber sensor. The optical fiber sensor is used to detect the diameter of the guide pin according to the sampling time, and determine whether the assembly groove of the guide pin is detected according to the diameter of the guide pin. If the assembly groove of the guide pin is detected, the abnormal guide pin is determined according to the time when the assembly groove of the guide pin is detected.

[0018] Optionally, there are several needle base stations on the station turntable. The needle base stations are arranged at equal intervals. There are a needle base placement groove and a spring piece on the needle base station. There are at least two notches on the needle base placement groove. The notches are docked with the assembly groove of the needle base, and the spring piece fixes the needle base in the needle base placement groove.

[0019] The present invention has the following beneficial effects: The present invention determines the moving direction of the guide pin on the conveying chute, that is, the moving direction with the assembly groove of the guide pin in the front, and determines the guide pin with the assembly groove in the back as an abnormal guide pin. There is a sorting sensor on the sorting chute to detect the abnormal guide pin, and a guide pin screening component is set to remove the abnormal guide pin from the sorting chute, which can reduce the time for debugging the assembly groove direction of the guide pin to match the assembly groove of the needle base and improve the efficiency; and the moving part is used to drive the guide pin clamping part, which can unify the assembly force and position dimension of pressing the assembly groove of the guide pin into the needle base each time, and reduce assembly defects.

[0028] For the convenience of understanding the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as "connected" to another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. The terms "upper", "one end", and "the other end" etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention.

[0030] In order to solve the technical problems existing in the prior art, a solution provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 - 3 , Figure 1 which is a schematic structural diagram of an MT guide pin automatic assembly device. In the figure, I1 represents an enlarged view of the station turntable, Figure 2 which is a schematic structural diagram of a press-fitting mechanism 3, Figure 3 which is an enlarged view of part I1 of the station turntable. Among them, the left figure represents the left view, and the right figure represents the right view. The present invention provides an MT guide pin automatic assembly device, which includes a material distribution tray 1, a conveying channel 2, a press-fitting mechanism 3, and a station turntable 4. The conveying channel 2 includes a sorting channel 21 and a linear vibrating channel 22. The press-fitting mechanism 3 includes a guide pin clamping component 32 and a moving component 31.

[0032] A sorting sensor and a guide pin screening component are arranged on the sorting channel 21. When the sorting sensor detects an abnormal guide pin, the guide pin screening component removes the abnormal guide pin from the sorting channel 21; an abnormal guide pin refers to a guide pin whose assembly groove 51 enters the sorting channel 21 later.

[0033] The sorting channel 21 is arranged in the material distribution tray 1 of the material distribution tray 1. One end of the linear vibrating channel 22 is connected to the sorting channel 21, and the other end of the linear vibrating channel 22 is docked with the guide pin clamping component 32. The guide pin clamping component 32 and the moving component 31 are connected, and the moving component 31 drives the guide pin clamping component 32 to press-fit the assembly groove 51 of the guide pin into the pin seat 42 on the station turntable 4.

[0034] Specifically, the material distribution tray 1 includes a tray and a vibration device, and the vibration device is used to drive the guide pins in the tray to spiral upward to the sorting channel 21.

[0035] The conveying channel 2 includes a sorting channel 21 and a linear vibrating channel 22. Among them, the conveying channel 2 is arranged in the tray of the material distribution tray 1, and the linear vibrating channel 22 is arranged between the material distribution tray 1 and the guide pin clamping component 32, as Figure 4 shown, Figure 4 which is an enlarged view of the linear vibrating channel 22. Guide pin conveying grooves 23 are arranged on both the sorting channel 21 and the linear vibrating channel 22. The end of the guide pin conveying groove 23 of the linear vibrating channel 22 is docked with the feeding hole 321 arranged on the guide pin clamping component 32. The linear vibrating channel 22 is connected to a linear vibrating device, so that the guide pins on the linear vibrating channel 22 are continuously conveyed forward.

[0036] As shown Figure 5 in the figure Figure 5 is a schematic diagram of the correct moving direction of the guide pin. A number of sorting sensors and guide pin screening components (not marked in the figure) are provided on the sorting channel 21. The number "a number of" means 1 or more. The sorting sensors include fiber optic sensors. The fiber optic sensors are used to detect the diameter of the guide pin according to the sampling time, and determine whether the assembly groove 51 of the guide pin is detected according to the diameter of the guide pin. If the assembly groove 51 of the guide pin is detected, the abnormal guide pin is determined according to the time when the assembly groove 51 of the guide pin is detected.

[0037] Determining the abnormal guide pin according to the time when the assembly groove 51 of the guide pin is detected may include: calculating the difference between the time of the assembly groove 51 of the guide pin and the time when the guide pin enters the sorting channel 21. If the difference is less than the preset value, it is determined as a normal guide pin; if the difference is greater than the preset value, it is determined as an abnormal guide pin. Specifically, if the assembly groove 51 of the guide pin is detected, the sorting sensor may output a first value, such as 400; if the guide pin entering the sorting channel 21 is detected, the sorting sensor may output a second value, such as 500; if it is detected that there is no guide pin in the sorting channel 21 (such as the gap between two guide pins), the sorting sensor may output a third value, such as 900.

[0038] The guide pin screening component may be a mechanism that outputs gas or other substances. If it is gas, the gas will blow the guide pins on the linear vibrating channel back into the distribution tray.

[0039] The diameters of the guide pin conveying groove 23 on the linear vibrating channel 22 and the sorting channel 21 are equal to the diameter of the guide pin. This can reduce the direction deviation when the guide pin moves forward, and can better dock with the feeding hole 321 at the end of the guide pin conveying groove 23, reducing the adjustment time for the guide pin to enter the feeding hole 321.

[0040] As shown Figure 2 in the figure, the guide pin clamping component 32 includes a feeding hole 321 and a clamping jaw 322. The feeding hole 321 and the clamping jaw 322 are at the same height, and the feeding hole 321 is docked with the other end of the linear vibrating channel 22. Specifically, the feeding hole 321 is docked with the end of the guide pin conveying groove 23 of the linear vibrating channel 22. The diameter of the feeding hole 321 is 1 - 2 times the diameter of the guide pin, and the horizontal distance between the clamping jaw 322 and the feeding hole 321 is less than the length of the guide pin. In this way, the guide pin can more easily enter the clamping jaw 322 and be clamped by the clamping jaw 322, reducing the time for debugging the correct clamping of the clamping jaw 322 to make the assembly groove 51 of the guide pin in the front.

[0041] The moving part 31 includes a clamping cylinder 311 and a proximity sensor 323, and the clamping cylinder 311 is connected to the proximity sensor 323. The proximity sensor 323 is used to detect whether a guide pin enters the jaw 322. If it detects that a guide pin enters the jaw 322, it notifies the clamping cylinder 311 to act. The clamping cylinder 311 is used to drive the jaw 322 to clamp and fix the guide pin 5 when the proximity sensor 323 detects that a guide pin enters the jaw 322.

[0042] The moving part 31 further includes a horizontal Y-axis cylinder 312 and a horizontal X-axis cylinder 313. Both the horizontal Y-axis cylinder 312 and the horizontal X-axis cylinder 313 are connected to the guide pin clamping part 32. The horizontal Y-axis cylinder 312 is used to drive the guide pin clamping part 32 to move along the Y-axis of the horizontal plane. The horizontal X-axis cylinder 313 is used to drive the guide pin clamping part 32 to move along the X-axis of the horizontal plane and press-fit the guide pin clamped by the guide pin clamping part 32 into the assembly groove of the pin socket. For example, first, the horizontal Y-axis cylinder 312 drives the guide pin clamping part 32 to advance to the assembly groove of the pin socket, and then the horizontal X-axis cylinder 313 drives the guide pin clamping part 32 to be assembled into the assembly groove of the pin socket.

[0043] As Figure 2 shown, the device further includes a guide pin baffle 6 and a lifting device 7. The lifting device 7 can be, but is not limited to, a slide table cylinder. The lifting device 7 is used to drive the guide pin baffle 6 to move to the other end of the linear vibrating chute 22 to block the guide pin conveying groove 23 of the linear vibrating chute 22 when the guide pin clamping part 32 moves towards the pin socket. Specifically, when the proximity sensor 323 detects that a guide pin enters the jaw 322, it notifies the lifting device 7, and the lifting device 7 drives the guide pin baffle 6 to move to the end of the linear vibrating chute 22 to block the end notch of the guide pin conveying groove 23, so that the guide pin will not fall from the guide pin conveying groove 23. When the guide pin clamping part 32 completes the assembly of the guide pin and returns, the lifting device 7 disengages from the end notch of the guide pin conveying groove 23, and the guide pin re-enters the feeding hole 321.

[0044] As Figure 3 shown, the station turntable 4 includes a number of pin socket stations 41. The pin socket stations 41 are arranged at equal intervals. A pin socket placement groove and a spring piece 411 are provided on the pin socket station 41. At least two notches are provided on the pin socket placement groove, and the notches are docked with the assembly groove of the pin socket. The spring piece 411 is used to fix the pin socket in the pin socket placement groove. The purpose of setting the notches is to expose the pin socket placement groove so that the guide pin can be smoothly assembled into the pin socket.

[0045] As Figures 6 - 7 shown, Figure 6 is a front view of an MT guide pin automatic assembly device, Figure 7It is a schematic diagram of a needle holder. The working station turntable 4 further includes a cam divider 43, a fixed disk 44, a working turntable 45, a needle holder push block, and a needle holder guide block 412. The fixed disk 44 is arranged on the cam divider 43. The working turntable 45 is rotatably fixed on the fixed disk 44. The needle holder station 41 is fixed on the working turntable 45. The needle holder push block, the needle holder guide block 412, and the elastic piece 411 are located on the needle holder station 41. The needle holder push block is used to limit the position of the rear side of the needle holder, so that the assembly notch of the needle holder is aligned with the notch of the needle holder placement groove. The needle holder guide block 412 is used to position the needle holder to make the direction of the needle holder correct. Specifically, the needle holder push block and the needle holder guide block 412 are installed in the needle holder placement groove. There is an assembled needle holder on the needle holder guide block 412, and the elastic piece 411 will press on the needle holder. The MT guide pin is loaded into the assembly grooves on both sides of the needle holder as shown in Figure 3 by the moving part 31.

[0046] According to the implementation result, it takes about 4 seconds to complete the assembly of the guide pin; achieving the assembly of one finished product in 4 seconds can achieve a production output of 900 pieces per hour. Compared with the manual assembly output of 100 - 200 pieces per hour, the assembly efficiency can be improved.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above.
