[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below through embodiments in conjunction with the accompanying drawings.

[0033] Example: Fixer, lock, sheath automatic assembly machine, such as Figure 1-14As shown, it includes a feeding mechanism 100, an assembly mechanism 200, a discharging mechanism 300 and a control unit 700, wherein the feeding mechanism 100 includes three vibration plates 101 and three feeding channels 102 for conveying a fixer 600, a lock 500 and a sheath 400 respectively. The vibration plate 101 is a common automatic assembly feeding device, which can automatically and orderly arrange disordered workpieces in an orderly and accurate manner through vibration and convey them to the workstations of each component through the feeding channel 102. In this embodiment, the lock 500 is S-shaped, and its bottom is a plug 501. The sheath 400 is provided with a slot 401 for the plug 501 to be inserted, and the fixer 600 can be embedded in the sheath 400.

[0034] The assembly mechanism 200 includes a sheath station 201 and a locking station 202 and a fixing station 203 respectively located on both sides of the sheath station 201. The locking station 202 and the fixing station 203 are respectively connected to the sheath station 201 through channels, wherein the channel width between the locking station 202 and the sheath station 201 is equivalent to the width of the locking station 500, and the channel width between the fixing station 203 and the sheath station 201 is equivalent to the width of the fixing station 600.

[0035] When the sheath 400, the lock 500, and the fixer 600 respectively enter the corresponding workstations, the plug 501 of the lock corresponds in height to the slot 401 of the sheath, so that the lock 501 can be assembled with the sheath 400 along the channel between the lock station 202 and the sheath station 201; the opening at the right end of the sheath 400 corresponds in height to the fixer 600, so that the fixer 600 can be assembled with the sheath 400 along the channel between the fixer station 203 and the sheath station 201.

[0036] A first cylinder 204 is provided on the outer side of the locking station 202, and a push rod 205 is connected to the output end of the first cylinder 204. When the plug 501 of the locking station is facing the sheath station 201, there is a gap on the side away from the sheath station 201; when the first cylinder 204 pushes the push rod 205, the front end of the push rod 205 can be inserted into the gap, thereby pushing the locking station 500 to move toward the sheath station 201 until the plug 501 of the locking station is inserted into the slot 401 of the sheath in the sheath station 201. The rear end of the push rod 205 extends backward, so that the length of the push rod 205 is greater than the distance between the locking station 202 and the sheath station 201, and the width of the push rod 205 is equivalent to the width of the lock 500, so that when the push rod 205 pushes the lock 500 for assembly, the side of the push rod 205 can block other locks in the feeding channel 102 of the lock 500 to prevent them from entering the locking station 202 in advance and interfering with the push rod 205. When the push rod 205 is reset, the next lock can enter the locking station 202.

[0037] A second cylinder 206 is provided on the outside of the fixer station 203 , and a push plate 207 is connected to the output end of the second cylinder 206 . When the second cylinder 206 pushes the push plate 207 , the push plate 207 pushes the fixer 600 to move toward the sheath station 201 until the fixer 600 is embedded in the sheath 400 . Similar to the aforementioned push rod 205, the rear end of the push plate 207 also extends backward, and the length of the push plate 207 in the horizontal direction is greater than the distance between the fixture station 203 and the sheath station 201, and the width of the rear end extension portion of the push plate 207 is equivalent to the width of the fixture 600, so that when the push plate 207 pushes the fixture 600 for assembly, the rear end extension portion of the push plate 207 can block other fixtures to be assembled in the feed channel 102 of the fixture 600, preventing them from entering the fixture station 203 in advance and interfering with the push plate 207. When the push plate 207 is reset, the next fixture can enter the fixture station 203.

[0038] In order to ensure the stability during assembly, the sheath 400 in the sheath station 201 needs to be kept stationary during assembly. In this embodiment, a side plate 208 is provided on the side of the sheath station 201 away from the feeding channel 102 of the sheath 400, and a third cylinder 209 is provided above the sheath station 201. The output end of the third cylinder 209 is downward and connected to a clamping device. Specifically, the clamping device includes two vertical clamping feet 210 and a vertical lateral positioning rod 211, wherein the end of the clamping foot 210 is made of elastic material, such as rubber. When the third cylinder 209 pushes the clamping device downward, the clamping foot 210 presses against the upper surface of the sheath 400. The spacing between the lateral positioning rod 211 and the side plate 208 is equal to the width of the sleeve 400, and the bottom end of the lateral positioning rod 211 is a pointed wedge-shaped rod to facilitate insertion between two adjacent sleeves. When the third cylinder 209 pushes the clamping device downward, the lateral positioning rod 211 and the side plate 208 are respectively located on both sides of the sleeve 400 to limit the lateral freedom of the sleeve 400. Combined with the aforementioned clamping foot 210, the sleeve 400 can be kept stationary during assembly.

[0039] In this embodiment, the length of the fixture 600 along the assembly direction is relatively small, and it may be displaced to a certain extent in the fixture station 203 due to machine vibration, so that other fixtures at the rear also enter the fixture station 203, and then there is a phenomenon that there are multiple fixtures in the fixture station 203, which will affect the normal progress of the assembly work. In order to further reduce the probability of errors during assembly, a fifth cylinder 212 is provided above the channel between the sheath station 201 and the fixture station 203. The output end of the fifth cylinder 212 is downward and is connected to a baffle 213. The shape of the baffle 213 matches the cross-sectional shape of the channel between the sheath station 201 and the fixture station 203, and is used to block or open the channel between the sheath station 201 and the fixture station 203, and to limit the fixture 600 in the fixture station 203. Before the third cylinder 209 works, the fifth cylinder 212 controls the baffle 213 to lift up, opening the passage between the sheath station 201 and the fixture station 203, so that the third cylinder 209 can push the fixture for assembly; after completing one assembly, the third cylinder 209 is reset, and then the fifth cylinder 212 controls the baffle 213 to move downward, isolating the passage between the sheath station 201 and the fixture station 203, and blocking the fixture 600 to prevent it from moving along the assembly direction.

[0040] In this embodiment, a sheath height limiting rod 214 is provided at the entrance of the sheath station 201, and the height of the sheath height limiting rod 214 matches the height of the sheath 400; a fixture height limiting rod 215 is provided at the entrance of the fixture station 203, and the height of the fixture height limiting rod 215 matches the height of the fixture 600. The sheath height limiting rod 214 and the fixture height limiting rod 215 are used to limit the sheath 400 or the fixture 600 that is incorrectly positioned or defective from entering the sheath station 201 or the fixture station 203, respectively.

[0041] The discharging mechanism 3 includes a fourth cylinder 301, a discharging cylinder 302 and a discharging hopper 303 arranged on the outside of the assembly mechanism. Specifically, in addition to the aforementioned side plate 208, the sheath station 201 also includes a bottom plate that can be moved up and down. The output end of the fourth cylinder 301 is connected to the bottom plate. The discharging cylinder 302 is horizontally arranged above the sheath station 201, and its output end is connected to a discharging push plate. When the lock 500, the fixer 600 and the sheath 400 are assembled, the fourth cylinder 301 pushes the bottom plate and the finished product assembled on the bottom plate to move up until they reach the same height as the discharging cylinder 302. Then the discharging cylinder 302 pushes the discharging push plate to push the finished product out and drop it into the discharging hopper 303.

[0042] In the above structure, the bottom of the discharge hopper 303 is open, and a receiving hopper 304 and a motor 305 for driving the receiving hopper 304 to rotate are arranged below it. The outer side of the receiving hopper 304 is connected to a downwardly inclined first discharge channel 306, and three adjacently arranged second discharge channels 307 are arranged below the first discharge channel 306. A collecting box 308 is respectively arranged below each second discharge channel 307, and a counter is arranged in the first discharge channel 306, which is electrically connected to the motor 305. By driving the receiving hopper 304 to rotate through the motor 305, the first discharge channel 306 can correspond to a different second discharge channel 307. After the finished product enters the discharge hopper 303, it continues to fall downward into the receiving hopper 304, passes through the first discharge channel 306 and continues to fall downward to its corresponding second discharge channel 307, and then falls into the collection box 308; a counter is set according to the capacity of the collection box 308. When the value recorded by the counter reaches the maximum capacity of the collection box 308, a signal is sent to the motor 305. The motor 305 drives the receiving hopper 304 to rotate a certain angle, so that the first discharge channel 306 corresponds to another second discharge channel 307, so that the finished product is collected in another collection box 308, and the collection box full of finished products is transferred and replaced with a new collection box.

[0043] In this embodiment, the control unit 700 includes a programmable logic controller, a touch screen, and a plurality of limit switches and position controllers. The first cylinder 204, the second cylinder 206, the third cylinder 209, the fourth cylinder 301, the fifth cylinder 212, and the discharge cylinder 302 are electrically connected to the programmable logic controller through a solenoid valve; the vibration plate 101, the motor 305, the counter, the touch screen, and a plurality of limit switches and position sensors are electrically connected to the programmable logic controller. The programmable logic controller receives inputs from sensing components such as limit switches, touch screens, and position sensors, and directly or indirectly outputs and controls the operation of the cylinders, motors, and vibration plates. The programmable logic controller can control the working sequence and working time of each cylinder, motor, and vibration plate according to the main program, so that each moving component cooperates in an orderly and compact manner, achieves the purpose of automated assembly, reduces manual operations, and improves work efficiency.

[0044] During the specific implementation of this embodiment, the vibrating disk 101 first delivers the fixer 600, the lock buckle 500, and the sleeve 400 to their respective stations through the corresponding feeding channel 102, and then the third cylinder 209 drives the clamping device to move downward to fix the sleeve 400; then the fifth cylinder 212 drives the baffle 213 to move upward to open the passage between the fixer station 203 and the sleeve station 201; then the first cylinder 204 and the second cylinder 206 simultaneously push the lock buckle 500 and the fixer 600 to move in the direction of the sleeve station 201 for assembly, and the finished product is formed after the assembly is completed; then the fourth cylinder 301 pushes the bottom plate and the finished product on the bottom plate upward, and the discharging cylinder 302 pushes the finished product into the discharging hopper 303 and the discharging mechanism 300 discharges the finished product, completing one finished product assembly, and then the next assembly work is carried out according to the above steps.

[0045] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
