[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-7As shown, an embodiment of the present invention discloses a blind plug rod and plastic plug assembly device, including a blind plug rod feeding mechanism a, a pressing mechanism b, a plastic plug feeding mechanism c and a unloading mechanism (illustrated in the figure), the blind plug rod feeding mechanism a is used to output a plurality of arranged blind plug rods one by one to the pressing mechanism b, the plastic plug feeding mechanism c is used to transport the plastic plug to the bottom of the pressing mechanism b, the pressing mechanism b is used to press the blind plug rod into the plastic plug to form a product, and the unloading mechanism is used to take out the product after the plastic plug feeding mechanism c withdraws from the pressing mechanism b.

[0028] like Figure 1-3 As shown, the blind stopper rod feeding mechanism a includes a vibration plate a1, a vibration selection component a2 and a vibration arrangement track a3. The vibration plate a1 is used to output the blind stopper rods K therein one by one to the vibration selection component a2 through vibration force. The vibration selection component a2 is used to receive the blind stopper rods K at the output end of the vibration plate a1 and select and convey the blind stopper rods in the correct direction. The vibration arrangement track a3 is used to receive the blind stopper rods in the correct direction at the end of the vibration selection component a2 and arrange the blind stopper rods K in the correct direction and move forward.

[0029] The vibration selection component a2 includes a receiving plate a21, a head side plate a22 and a tail side plate a23. The receiving plate a21 is located at the tail of the vibration disk a1. The head side plate a22 and the tail side plate a23 are respectively arranged at one end of the receiving plate a21 and are respectively fixedly connected to the receiving plate a21. A set area is provided between the head side plate a22 and the tail side plate a23 to form a hole a24 for the blind plug rod to leak down. The end of the head side plate a22 away from the receiving plate a21 is higher than the end of the head side plate a22 connected to the receiving plate a21, and the head side plate a22 is higher than the tail side plate a23 as a whole. The tail side plate a23 is a flat plate parallel to the ground. When the head of the blind plug rod is placed on the head side plate a22 and the groove at its tail is stuck on the tail side plate a23, the blind plug rod vibrates through.

[0030] The vibration arrangement track a3 includes a linear vibrator (not shown in the figure) and a conveying track a32. The bottom of the conveying track a32 is connected to the linear vibrator. The conveying track a32 includes an inclined track a321 located in the front and a straight conveying track a322 located in the rear. The inclined track a321 is respectively connected to the head side plate a22 and the tail side plate a23.

[0031] The closer the inclined track a321 is to the straight conveying track a322, the greater the inclination angle of the inclined track a321 is until it is well connected with the straight conveying track a322.

[0032] The blind plug rod feeding mechanism a also includes a sensor and a blowing component. The sensor is arranged at one end of the vibration arrangement track a3 close to the vibration selection component a2. When the sensor senses that the head of the vibration arrangement track a3 is also full of blind plug rods, it blows away the excess blind plug rods.

[0033] A receiving bin (not shown) is provided below the vibration selection assembly a2, and is used to receive blind plug rods that are not properly transported. The receiving bin is connected to the vibration plate a1, so that the blind plug rods are input into the vibration plate a1 again.

[0034] The working principle of the blind plug rod feeding mechanism a is as follows:

[0035] First, under the action of vibration force, the blind plug rod in the vibration disk a1 is output to the receiving plate a21 through the vibration disk a1's own track, and then, the blind plug rod on the receiving plate a21 is transported to the head side plate a22 and the tail side plate a23 under the action of vibration force. When the head of the blind plug rod is placed on the head side plate a22 and the groove of its tail is stuck on the tail side plate a23, the blind plug rod can move from one end of the head side plate a22 and the tail side plate a23 to the other end under the action of vibration force, and enter the inclined track a321. The inclined track a321 transports the blind plug rod forward under the action of vibration force, and under the changing inclination angle of the inclined track a321, the blind plug rod can gradually adjust its own inclination state until it transitions to the straight conveying track a322. The straight conveying track a322 drives the blind plug rod to continue moving forward under the action of vibration force until it is transported to the next station - the pressing station. The receiving plate a21, the vibration selection assembly a2, and the vibration arrangement track a3 are connected together, and the vibration force all comes from the linear vibrator.

[0036] See also Figure 3-6 As shown, the pressing mechanism b includes a pressing component b1, a supporting mechanism b2 and a moving component b3. The supporting mechanism b2 is arranged on the moving component b3. The moving component b3 is used to transport the supporting mechanism b2 to the bottom of the pressing component b1 for pressing. The supporting mechanism b2 includes a slide cylinder b21 fixed on the moving component b3, a supporting fixture b22 fixedly connected to the slide of the slide cylinder b21, and a guide plate b23 mounted above the supporting fixture b22. The slide cylinder b21 is used to drive the supporting fixture b22 to move to the bottom of the guide plate b23 or away from the guide plate b23. A plurality of guide holes are arranged on the guide plate b23, and the guide holes correspond one by one to the holes on the plastic plug placed in the supporting fixture b22.

[0037] The pressing assembly b1 includes a cross beam b11, a fixing plate b12 fixed on the cross beam b11, a first lifting cylinder b13 fixed above the fixing plate b12, a pressing needle b15 fixedly connected to the telescopic rod of the first lifting cylinder b13, and a guide block b14 embedded in the lower end of the fixing plate b12, and the pressing needle b15 passes through a guide hole on the guide block b14.

[0038] The moving assembly b3 comprises a two-axis linkage mechanical arm b31 which is linked in two axes, X and Y. The slide cylinder b21 is fixed on the two-axis linkage mechanical arm b31 via a connecting plate.

[0039] The plastic plug feeding mechanism c comprises a conveyor belt for conveying the plastic plugs, and the tail of the conveyor belt is located on one side of the slide cylinder b21.

[0040] The blind plug rod pressing mechanism b also includes a workpiece grabbing assembly b5, which is used to grab the plastic plug on the conveyor belt to the carrying fixture b22. Among them, the workpiece grabbing assembly b5 includes a clamping cylinder, a second lifting cylinder b51 that drives the clamping cylinder to rise and fall, and a translation cylinder b52 that is fixedly connected to the cylinder body of the second lifting cylinder b51.

Among them, the translation cylinder adopts a slide cylinder with a guide rod, and the second lifting cylinder is fixedly connected to the cylinder body of the slide cylinder.

[0041] The working principle of the blind plug rod pressing mechanism b is as follows:

[0042] The conveyor belt transports the workpiece - the plastic plug to the location of the slide cylinder b21, and then the second lifting cylinder moves downward to the set height, and the clamp cylinder grabs the plastic plug. Then, the second lifting cylinder rises to the set height, and the translation cylinder drives the plastic plug to move above the sleeve cylinder. Finally, the second lifting cylinder descends to the set height again, and the clamp cylinder places the plastic plug on the carrier fixture b22.

[0043] The workpiece - plastic plug is placed on the carrier jig b22, and the slide cylinder b21 drives the carrier jig b22 to move to the bottom of the guide plate b23. At this time, the holes on the plastic plug on the carrier jig b22 correspond to the guide holes on the guide block b14 one by one. Then the moving component b3 works, that is, the two-axis linkage robot arm b31 drives the X-axis and Y-axis of the carrier jig b22 to move in linkage, thereby driving the carrier jig b22 to move to the bottom of the pressing component b1.

[0044] The first lifting cylinder b13 drives the pressing needle b15 to press down, and the blind plug rod transported to the guide block b14 in the blind plug rod conveying process is pressed onto the plastic plug through the guide hole on the guide plate b23 (wherein, a product conveying channel connected to the straight conveying track a322 of the blind plug rod conveying process is provided in the guide block b14, and the conveying channel is connected to the guide hole on the guide block b14. When the pressing needle b15 is pressed down, the blind plug rod in the product conveying channel is pressed down onto the plastic plug).

[0045] Finally, after the assembly is completed, the carrying fixture b22 is withdrawn from the bottom of the pressing mechanism, and the unloading mechanism unloads the product to the set position for inspection, and then packs it after the inspection is completed. The unloading mechanism can be a robotic arm.

[0046] Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
