[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work shall fall within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figure 1-9 As shown,

[0047] A capillary automatic assembly device, comprising a capillary tube support feeding device provided on a workbench 3, a capillary tube support adjusting device 5 connected to the capillary tube support feeding device, a capillary tube feeding device provided on the workbench 3, a feeding device for mounting a capillary tube 77 on a capillary tube support 83, and a control device;

[0048] The control device is respectively connected with the capillary support feeding device, the capillary support adjusting device, the capillary feeding device and the feeding device via signals.

[0049] The capillary support feeding device includes a first vibrating feeder 2 mounted on a workbench 3 and a conveying channel 8 docked with a discharge port of the first vibrating feeder 2;

[0050] like Figure 4 As shown, the conveying channel 8 is V-shaped (referred to as a corner slide); the conveying channel 8 includes a straight channel 82 and a curved channel 84; the curved channel 84 abuts against the discharge port of the first vibrating feeder 2; the straight channel 82 is connected to the capillary support adjustment device 5;

[0051] When the capillary tube holder 83 is adjusted and the capillary tube 77 is installed, the entire platform cannot be vibrated, and the capillary tube holder 83 cannot be transported by vibration;

[0052] A first cylinder 81 for pushing the capillary tube support 83 and a capillary tube support detection device are provided at the V-shaped bend of the conveying channel 8; the cylinder rod of the first cylinder 81 is directed toward the capillary tube support adjustment device 5;

[0053] The capillary support detection device includes detection holes provided at the corners of both side walls of the delivery channel 8 and a first set of photoelectric switches 85 for detecting the capillary support 83 through the detection holes;

[0054] The first group of photoelectric switches 85 and the first cylinder 81 are both connected to the control device by signal.

[0055] After the first vibrating feeder 2 sends the capillary tube bracket 83 to the corner slide through vibration, the capillary tube bracket 83 is pushed to the corner position by the vibration thrust. When the first group of photoelectric switches 85 that determine that the capillary tube bracket 83 is in place senses the capillary tube bracket 83, the vibration stops, and the cylinder rod of the first cylinder 81 on the corner slide pushes the capillary tube bracket 83 forward, giving the capillary tube bracket 83 forward power; the reason for using the corner is that the cylinder rod cannot block the bracket from moving to the corner position by vibration when it is recovered.

[0056] The capillary support adjustment device 5 includes a support 52 mounted on the workbench 3, a first dual-output motor 54 whose housing is mounted on the support 52, a coupling 53 fixedly mounted on one end of the first dual-output motor 54, a shift fork 51 fixedly connected to the coupling 53, and a rotation angle control device provided at the other end of the first dual-output motor 54;

[0057] The rotation angle control device includes a dividing plate 55 provided at the other end of the first dual-output motor 54 and a second group of photoelectric switches 56 for detecting the rotation angle of the dividing plate 55; the dividing plate 55 is provided with two light holes 551 symmetrical about the center of the dividing plate 55; the second group of photoelectric switches 56 is adapted to the light holes 551; the second group of photoelectric switches 56 and the first dual-output motor 54 are both connected to the control device signal.

[0058] Capillary support 83 posture adjustment position:

[0059] A baffle is provided on the conveying channel 8 to prevent the capillary bracket 83 from rotating; a section of the baffle is missing, so that the capillary bracket 83 can rotate at this position, and a shift fork 51 for posture adjustment is provided just above this position. The shift fork 51 is upright in the posture adjustment position and acts as a baffle of the conveying channel 8 when not working. The capillary bracket 83 passes through the middle of the shift fork 51; the shift fork 51 is slotted in the center, and the width of the slot is adapted to the capillary bracket 83; an observation hole is provided on the side wall of the slot, and a group of sensors 57 are provided on the outside of the observation hole; if the posture is not the set posture, the controller issues a start command to rotate 180 degrees

[0060] There are two sensors 57. Utilizing the eccentric structure of the top of the capillary support 83, the upper sensor 57 observes the eccentric position of the head of the capillary support 83, and the lower sensor 57 detects the lower part of the capillary support 83.

[0061] When the capillary support 83 reaches the posture adjustment position, the lower sensor 57 determines whether the capillary support 83 is in place; the upper sensor 57 that determines the front and back of the capillary support 83 determines the posture of the support;

[0062] Whether the capillary mounting head on the capillary support 83 is facing forward. If so, the attitude adjustment fork 51 does not work and the capillary support 83 passes directly.

[0063] If the capillary mounting head is facing backward, the posture adjustment fork 51 is driven by the first dual-output motor 54 to rotate 180 degrees, thereby driving the capillary bracket 83 to rotate 180 degrees, so that the capillary mounting head faces forward. This is repeated until all the capillary mounting heads on the capillary bracket 83 face forward, facilitating the installation of the capillary 77.

[0064] The capillary feeding device includes a second vibrating feeder 1 installed on the workbench 3, a capillary feeding channel 4 connected to the discharge port of the second vibrating feeder 1, and a receiving device 7 for receiving the material from the capillary feeding channel 4; the capillary 77 vibrates and advances in the capillary feeding channel 4;

[0065] The material receiving device 7 includes a mounting base 72 fixedly connected to the workbench 3, a posture adjusting wheel 71 rotatably connected to the mounting base 72, a second coupling 74 fixedly connected to the posture adjusting wheel 71, and a second dual-output motor 73 with one end transmission connected to the coupling 74; four material receiving grooves 78 are evenly distributed along the circumferential top surface of the posture adjusting wheel 71; the material receiving grooves 78 are used to receive the capillaries 77 transmitted from the capillary feeding channel 4.

[0066] The mounting seat 72 is also provided with a rotation control device for controlling the rotation angle of the posture adjustment wheel 71; the rotation control device includes a positioning plate 75 provided at the other end of the second dual-output motor 73 and a third group of photoelectric switches 76 for detecting the rotation angle of the positioning plate 75; the third group of photoelectric switches 76 and the dual-output motor 73 are both signal-connected to the control device.

[0067] There are four evenly distributed detection holes on the positioning plate 75. When the third group of photoelectric switches 76 observes the detection holes, it sends a signal to the controller, and the controller sends a signal to the second dual-output motor 73, so that the posture adjustment wheel 71 can rotate according to the set angle.

[0068] The principle is similar to that of the first dual-output motor 54 and will not be described in detail. This avoids misjudgment caused by only one set of photoelectric switches controlling the action signals of the dual-output motor 73.

[0069] The shape and size of the receiving groove 78 can just fit into the barbed end of the capillary tube 77, and the receiving groove 78 is aligned with the feeding channel 4 of the capillary tube 77;

[0070] The feeding device 6 includes a base 61 detachably connected to the workbench 3, a transverse guide rail 63 fixedly connected to the base 61, a vertical guide rail seat 64 slidably connected to the transverse guide rail 63, and a pneumatic finger 66 slidably connected to the vertical guide rail seat 64; the pneumatic finger 66 is used to clamp the capillary 77.

[0071] The feeding device 6 also includes a power device for providing power for the pneumatic finger 66 to move vertically and the vertical guide rail seat 64 to move horizontally.

[0072] The power device includes a horizontal cylinder 62 whose cylinder body is fixedly connected to the base 61 and a vertical cylinder 65 whose cylinder rod is fixedly connected to the cylinder body of the pneumatic finger 66; the cylinder body of the vertical cylinder 65 is fixedly connected to the vertical guide rail seat 64; the cylinder rod of the horizontal cylinder 62 is fixedly connected to the vertical guide rail seat 64.

[0073] Capillary installation position:

[0074] like Figure 10-11 As shown, the capillary 77 is installed at this position, and the capillary bracket 83 needs to be positioned during installation; there is a positioning fork 91 at this position, the positioning part of the positioning fork 91 is a V-shaped structure, and the other end is fixedly connected to the positioning cylinder 92;

[0075] When positioning is required, the positioning cylinder 92 pushes the positioning fork 91 forward, and the V-shaped fork clamps the cylinder on the capillary tube holder 83, and together with the conveying track 8, completely fixes the capillary tube holder 83, so that the capillary tube holder 83 cannot move forward or backward or rotate;

[0076] After the capillary tube 77 is installed, the positioning cylinder 92 drives the positioning fork 91 to move backward to clear the passage, and the support cylinder pushes the support forward; the next capillary tube 77 and capillary support 83 are installed;

[0077] The control device is a PLC controller, which is used to receive signals from various photoelectric switches and sensors and control the actions of various cylinders and motors. The programs used are all existing technologies.

[0078] The working process of the present invention,

[0079] The first vibrating feeder 2 delivers the capillary tube bracket 83 to the corner of the conveying channel 8. When the first group of photoelectric switches 85 detects the signal that the capillary tube bracket 83 is in place, the first cylinder 81 pushes the capillary tube bracket 83 forward.

[0080] The sensor 57 of the position of the posture adjustment fork 51 determines that the direction needs to be adjusted, and then the fork 51 rotates 180 degrees to adjust the capillary bracket 83; finally, the capillary bracket 83 is pushed into place, and then the positioning fork 91 of the positioning cylinder 92 positions the capillary bracket 83 to prevent rotation when installing the capillary 77;

[0081] The second vibrating feeder 1 vibrates and feeds the capillary tube 77 along the capillary tube feeding channel 4. Since the receiving groove 78 of the posture adjustment wheel 71 is opposite to the discharge port of the capillary tube channel 4, the barb of the capillary tube is inserted into the receiving groove 78. When the capillary tube 77 is inserted, the posture adjustment wheel 71 rotates 90 degrees so that the capillary tube 77 faces upward.

[0082] Start the horizontal cylinder 62 so that the pneumatic finger 66 is located directly above the capillary 77. Start the vertical cylinder 65, which drives the pneumatic finger 66 downward. The pneumatic finger 66 clamps the capillary 77 and then sends the capillary 77 to directly above the capillary bracket 83. The vertical cylinder 65 moves to install the capillary 77 on the capillary bracket 83. The pneumatic finger 66 releases and the cylinder rod of the positioning cylinder 92 is withdrawn; the automatic installation is completed.

[0083] Example 2

[0084] This embodiment has the same structure as embodiment 1.

[0085] The difference is that

[0086] The workbench 3 is divided into three independent parts (not shown in the drawings, which is common knowledge). The three parts are separated from each other and are not directly connected together. Two of the workbenches are respectively equipped with a vibrating feeder to prevent the vibration generated by the two vibrating feeders from affecting the stability of other parts.

[0087] The workbench 3 is provided with height-adjustable legs 31 for easy alignment.

[0088] Example 3

[0089] The structure of this embodiment is basically the same as that of embodiment 1.

[0090] The difference is that

[0091] like Figure 2 As shown, the end of the posture adjustment wheel 71 is further provided with a detection device for detecting whether there is the capillary 77 in the material receiving groove 78 of the posture adjustment wheel 71;

[0092] The detection device includes a light-transmitting hole 79 that penetrates the material receiving groove 78 and a fourth set of photoelectric switches for detecting whether the capillary tube 77 is inserted into the material receiving groove 78;

[0093] There are four receiving troughs 78, which are evenly distributed along the top surface of the circumference of the posture adjustment wheel 71;

[0094] The fourth group of photoelectric switches includes a first detection switch 791 and a second detection switch 792; the first switch 791 and the second switch 792 are both connected to the controller signal.

[0095] The first switch 791 detects through the light-transmitting hole 79 whether the capillary 77 conveyed from the capillary feeding channel 4 is inserted into the receiving groove 78 when the receiving groove 78 of the posture adjustment wheel 71 is in the horizontal state;

[0096] When the capillary tube 77 is pushed by the vibration, the end of the capillary tube 77 with the barb will enter the material receiving groove 78, and the end of the capillary tube 77 can just block the light-transmitting hole 79.

[0097] If there is a capillary tube 77 in the receiving slot 78 at that position, the light-transmitting hole 79 at that position is blocked; the first switch 791 transmits a signal to the controller, which sends a signal to the attitude adjustment wheel 71 to rotate 90 degrees. The controller then sends a signal to the feeding device, and the pneumatic finger 66 of the feeding device clamps the capillary tube 77 and installs it on the capillary tube holder 83;

[0098] If the first switch 791 does not detect the capillary tube 77, the controller sends an alarm signal to the alarm device to remind personnel to check;

[0099] The second switch 792 is used to detect whether the capillary 77 in the material receiving trough 78 of the posture adjustment wheel 71 is removed when it rotates 90 degrees from the vertical upward state to the horizontal state; if the light-transmitting hole 79 at this position is blocked by the capillary 77, manual intervention is required. If the capillary 77 in the light-transmitting hole 79 here has been removed, the controller receives the signal of the second switch 792 and determines that the material receiving trough 78 at this position is empty. Combined with the two signals given by the first switch 791 that the capillary 77 is stored in the material receiving trough 78 at this position, the controller will send a rotation signal to the second dual-output motor 73 to avoid errors.

[0100] The above description is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved conception of the present invention shall be covered within the protection scope of the present invention.
