[0032] The principle of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] As Figure 1 , 2 shown, the automatic insertion device proposed by the present invention is applicable to the plug-in assembly of materials and components. The component is provided with insertion holes, and the processed material 28 is provided with pins that are inserted and matched with the insertion holes. Here, the processed material 28 refers to the material whose pins have been processed according to the insertion requirements, and the insertion requirements are determined according to the actual situation. For example, the pins of the material are cut to an appropriate length, and then the ends of the pins are bent downward to form a working portion 31 ( Figure 9 shown in

[0034] ), and the working portion 31 is inserted into the insertion holes of the component. Specifically, the automatic insertion device mainly includes three major parts: a component transportation device, a feeding device 4, and a moving and guiding device 5, which play a role in supporting and fixing the entire device. A touch screen 2 is provided on the upper part of the frame. The touch screen 2 serves functions such as device information display and device operation. The frame bottom plate 3 is located in the middle of the frame 1. The component transportation device, the feeding device, and the moving and guiding device are all installed on the frame bottom plate 3. Each part will be described in detail below. It should be noted that in the following text, in-place detectors are provided at both the insertion station and the preparatory station. The in-place detector can be an optoelectronic switch, etc. The electric components mentioned in the following text can be cylinders, etc.

[0035] As Figures 2 to 5As shown in the figure, the plug transportation device is used to transport the plug 8 to the insertion station. The plug transportation device includes a track assembly and a baffle mechanism. The track assembly transports the plug 8 in the horizontal direction. The track assembly is installed on the frame bottom plate 3. The track assembly is composed of a fixed track 6 and a movable track 7, forming a two-section track transmission system with adjustable width. The first transportation motor 14 and the second transportation motor 15 are installed at intervals on the fixed track 6, driving the operation of the track chain, thereby driving the plug 8 to move on the track. The fixed track 6 is also installed with a first photoelectric switch 9, a second photoelectric switch 10, a third photoelectric switch 11, and a fourth photoelectric switch 12, which are used to detect the transmission situation of the plug. The baffle mechanism includes: a baffle 56 that can move to the movement path of the plug, and a baffle electric component 55 that drives the movement of the baffle 56. The baffle electric component 55 is installed behind the third photoelectric switch 11 on the fixed track 6. The plug 8 is blocked or released by the baffle to achieve the preliminary positioning of the plug, that is, when the plug 8 moves to abut against the baffle 56, the plug 8 reaches the insertion station.

[0036] The feeding device is used to transport the processed material 28 to the preparation station. The feeding device can only have the transportation function, that is, the processed material is manually placed on the feeding device, and then the feeding device transports the processed material 28 to the preparation station. In a preferred embodiment, the feeding device not only has the transportation function but also can realize the processing of the material. The feeding device includes: a storage box, a pushing mechanism, a material transportation mechanism, and a material processing mechanism.

[0037] The storage box is composed of a first placement rack 36 and a second placement rack 37 arranged oppositely. The first placement rack 36 and the second placement rack 37 are installed on the storage box bottom plate 33. The storage box bottom plate 33 is fixed on the frame bottom plate 3 by installing adjustment columns 39. The storage box bottom plate 33 is placed obliquely. The second placement rack 37 is located below the first placement rack 36. A cavity for stacking and placing materials is formed between the first placement rack 36 and the second placement rack 37. One side of the bottom of the storage box is provided with a discharge port. The pushing mechanism is used to push the bottommost material in the storage box out of the discharge port. The pushing mechanism is composed of a pushing block 35 and a push tube electric component 34 that drives the movement of the pushing block 35.

[0038] The material transportation mechanism includes: a material plate 53 at the top for receiving the material pushed out of the storage box, an inclined guide rail 44 connected to the bottom end of the material plate 53, and a vibrating track connected to the bottom end of the inclined guide rail 44. The end of the vibrating track is the preparatory station, and a first in-place detection switch 47 is provided at the end of the vibrating track. The vibrating track moves the processed material 28 towards the preparatory station through vibration. Flat vibrators 46 are installed below both the inclined guide rail 44 and the vibrating track to convey the sheared material. The flat vibrators 46 are fixed to the machine frame bottom plate 3 through mounting columns 48. To ensure the stability of the rectifier bridge's fall, a vibration generator 38 is installed on the bottom plate 33 of the storage box to provide vibration for the smooth sliding of the processed material 28.

[0039] The material processing mechanism includes a lead cutting mechanism 40 and a lead bending mechanism 41 provided on one side of the inclined guide rail 44. The material slides down along the inclined guide rail 44 and passes through the lead cutting mechanism 40 and the lead bending mechanism 41 in sequence. The lead cutting mechanism 40 is used to cut the leads of the material, and the lead bending mechanism 41 is used to bend the leads of the material 28 downward.

[0040] Further, the material plate 53 is installed outside the discharge port of the storage box through a hinge 52. A material detector 47 is provided at the bottom end of the material plate 53, and the material detector 47 is installed on the second placement rack 37. The material transportation mechanism further includes: a retaining block 50 for preventing the material on the material plate 53 from slipping out, a retaining electric component 49 for driving the retaining block 50 to approach or move away from the material plate, and a discharging electric component 51 for pushing the material plate 53 to rotate. The material plate 53 is located between the discharge port and the retaining block 50. When the material detector 47 detects an abnormality in the material, the retaining electric component 49 drives the retaining block 50 to move away from the material plate 53, and the discharging electric component 51 drives the material plate 53 to rotate to discard the material downward.

[0041] As Figures 6 to 11 shown, the moving and guiding device includes: a moving mechanism for transporting the processed material 28, and a guiding mechanism for guiding the leads of the processed material 28 to align with the insertion holes. The guiding mechanism is provided with a guiding hole that can be opened or closed. When the leads of the processed material 28 are inserted downward into the insertion holes, the guiding hole is located between the insertion hole of the plug-in and the leads of the processed material, and the guiding hole is axially aligned with the insertion hole of the plug-in. The moving mechanism is composed of a suction cup frame 23, and a first suction cup 26 and a second suction cup 27 installed on the bottom surface of the suction cup frame 23. The two suction cups work simultaneously to suck the processed material 28.

[0042] In a preferred embodiment, the guiding hole is conical, with the larger-diameter end of the guiding hole 32 facing upward and the smaller-diameter end facing downward. A horizontally protruding pin is provided on the side of the processed material facing the guiding mechanism. The guiding hole of the guiding mechanism extends towards the pin of the processed material. The end of the pin is bent downward to form a working portion, and the working portion passes through the guiding hole and is inserted into the jack. The guiding mechanism includes: a connecting plate 24, a first clamping member 29 and a second clamping member 30 mounted on the connecting plate 24. The first clamping member 29 and the second clamping member 30 approach or move away from each other under the drive of the clamping electric member 25. A first guiding finger is provided at intervals at the bottom end of the first clamping member 29, and a second guiding finger paired with the first guiding finger one by one is provided at the bottom end of the second clamping member 30. A second guiding finger is provided between two adjacent first guiding fingers. When the first clamping member 29 and the second clamping member 30 approach each other, the bottoms of each pair of first guiding fingers and second guiding fingers are closed to form a guiding hole 32. When the first clamping member 29 and the second clamping member 30 move away from each other, the bottoms of each pair of first guiding fingers and second guiding fingers are opened, and the guiding holes are separated to be able to pass through the pins of the processed material from bottom to top, so that the guiding holes are separated from the processed material.

[0043] The automatic insertion device further includes: a first detection camera 13 for detecting whether the processed material 28 is qualified. When the first detection camera 13 detects unqualified, the moving mechanism discards the processed material. The moving guiding device further includes: a second detection camera 19. When the moving mechanism moves the processed material 28 above the insertion station, the second detection camera 19 identifies and locates the jacks of the plug-in parts 8; the guiding mechanism moves synchronously with the moving mechanism, and the moving mechanism receives the detection signal of the second detection camera 19 and adjusts the positions of the processed material and the guiding mechanism.

[0044] In a preferred embodiment, the moving mechanism, the guiding mechanism, and the second detection camera 19 are all mounted on a four-axis robot 54. The four-axis robot 54 is mounted on the frame bottom plate 3 through a base 16. A fixture assembly 18 is provided on the four-axis robot. The fixture assembly 18 is provided with a first robotic arm 20 and a second robotic arm 17. The moving mechanism is mounted on the first robotic arm 20. The moving mechanism is mounted on the first robotic arm 20 through a first lifting electric member 22, and the first lifting electric member 22 drives the moving mechanism to lift and lower. The guiding mechanism is mounted on the second robotic arm 17. The guiding mechanism is mounted on the second robotic arm 17 through a second lifting electric member 21, and the second lifting electric member 21 drives the guiding mechanism to lift and lower. The moving mechanism and the guiding mechanism are arranged oppositely, and the second detection camera 19 is located on the back of the second robotic arm 17.

[0045] As Figure 2 shown, taking the material as the tubular rectifier bridge 42 and the plug-in part as the PCB board 8 as an example, the working process of the automatic insertion device is as follows.

[0046] Feeding in: Before the device feeds in a board, the baffle electric component 55 drives the 56 baffles to drop, being in the baffle state. The PCB board enters through the track formed by the track fixed rail 6 and the track fixed rail 7. After being detected by the first optoelectronic switch 9, the first conveying motor 14 drives the first section of the belt to run, driving the PCB board to run. After reaching and being detected by the third optoelectronic switch 11, the first conveying motor 14 stops running after a 1-second delay. The preliminary positioning of the PCB board ends, and at the same time, it notifies the 4-axis robot that the PCB board has arrived in place.

[0047] Feeding: The worker places a stack of tubular rectifier bridges 42 into the storage box. The material blocking electric component 49 is in the extended state, pushing out the material blocking block 50 to form a state of blocking the tubes; the unloading electric component 51 is in the extended state, pushing the material plate 53 to be flush with the bottom plate 33 of the storage box. After the worker loads the tubular rectifier bridges, the feeding is started on the touch screen 2. The tube pushing electric component 34 drives the pusher block 35 to push out, and at the same time, the bottommost tubular rectifier bridge 42 in the storage box is pushed out and pressed tightly against the material blocking block 50. Since the entire feeding device is installed obliquely, the rectifier bridges slide down along the inclined guide rail 44 and reach the pin shearing mechanism 40 where the pins are sheared to the specified length by the pin shearing mechanism 40. Then, through the pin bending mechanism 41, the pins are bent to the specified angle. The rectifier bridges with bent corners continue to slide down to the vibrating track and are neatly arranged to the first in-place detection switch 47 through vibration and are detected. When 1 second has passed since the first in-place detection switch 47 detects the rectifier bridge, the flat vibrator 46 stops vibrating and notifies the four-axis robot 54 that the rectifier bridge has arrived in place and the material taking operation can be carried out.

[0048] When the rectifier bridge is detected by the material detector installed at the end of the inclined guide rail 44 during the process of sliding down along the inclined guide rail 44, if the material detector does not detect the rectifier bridge continuously for 3 seconds, it is considered that all the rectifier bridges on the material plate 53 have been processed, and the operation of discarding the empty tubes is carried out. The material blocking electric component 49 retracts to retract the material blocking block 50, and the unloading electric component 51 retracts to rotate the material plate 53 downward along the hinge 52 axis to throw the empty rectifier tubes downward. After the unloading electric component 51 retracts to the in-place position, it is considered that the throwing of materials is over. The unloading electric component 51 and the material blocking electric component 49 extend again to re-circulate the process of pushing the tubes and feeding. To ensure the stability of the rectifier bridge's fall, a vibration generator 38 is installed on the bottom plate 33 of the storage box to provide vibration for the smooth sliding of the rectifier bridges.

[0049] Material picking and insertion: When the rectifier bridge is in place, the four-axis robot 54 drives the fixture assembly 18 to the material picking position. At this time, the second lifting electric component 21 and the first lifting electric component 22 retract, and the clamping electric component 25 is in an open state. After reaching the material picking position, the first lifting electric component 22 extends, and the four-axis robot 54 drives the fixture assembly 18 to move downward, pressing the first suction cup 26 and the second suction cup 27 against the surface of the rectifier bridge. The first suction cup 26 and the second suction cup 27 turn on the vacuum to suck the rectifier bridge. The four-axis robot 54 drives the fixture assembly 18 to move upward and moves the rectifier bridge to the first detection camera 13 to detect the pins of the rectifier bridge. If the detection is unqualified, the rectifier bridge is discarded. If it is qualified, the four-axis robot 54 brings the rectifier bridge above the plug-in. The second detection camera 19 locates the rectifier bridge insertion holes on the PCB board and transmits the positioning data to the four-axis robot 54 to adjust the position of the fixture assembly 18. After the four-axis robot 54 drives the fixture assembly 18 to be detected by the first detection camera 13, the first lifting electric component 22 retracts, and the second lifting electric component 21 extends. After extending in place, the clamping electric component 25 closes, and at the same time drives the first clamping member 29 and the second clamping member 30 to approach and close to form a conical guiding hole, which facilitates inserting the pins of the rectifier bridge into the PCB board. After the four-axis robot 54 corrects the position of the fixture assembly 18 and moves downward, the first clamping member 29 and the second clamping member 30 are closed to form a conical guiding hole alignment and are attached to the pin insertion holes of the rectifier bridge. The first lifting electric component 22 extends, and the pins of the rectifier bridge are inserted into the pin insertion holes of the rectifier bridge on the PCB board through the conical guiding hole formed by the closing of the first clamping member 29 and the second clamping member 30. After inserting in place, the first suction cup 26 and the second suction cup 27 turn off the vacuum to release the rectifier bridge. After a 1S delay, the first lifting electric component 22 retracts, the clamping electric component 25 opens, and at the same time drives the first clamping member 29 and the second clamping member 30 to open. The second lifting electric component 21 retracts, and the four-axis robot 54 drives the fixture assembly 18 to rise. After rising in place, an end-of-insertion instruction is given to the track plug-in, and the PCB board is sent out. At the same time, the four-axis robot 54 drives the fixture assembly 18 to execute the next material picking and insertion process.

[0050] PCB board output: When the track receives the end-of-insertion instruction given by the four-axis robot 54, the baffle electric component 55 drives the baffle 56 to lift. After lifting in place, the first conveying motor 14 and the second conveying motor 15 rotate simultaneously to drive the two sections of belts to run, and the PCB board is taken out of one section of the track. After leaving the third optoelectronic switch 11, the first conveying motor 14 stops running. When the PCB board reaches the fourth optoelectronic switch 14, the second conveying motor 15 stops rotating. After the lower computer gives a board request signal, the second conveying motor 15 continues to rotate and stops rotating after taking the PCB board out of the second section of the track.

[0051] The present invention also proposes an air conditioner, including: a main control board and a rectifier bridge, and the main control board and the rectifier bridge are plugged and assembled using the above automatic insertion equipment.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
