At present, manual installation is required. Workers install the buttons one by one into the product, and then the assembled product is detected. However, this installation method has problems such as low efficiency and high labor intensity. To improve this situation, an automated device needs to be designed to replace manual assembly. However, when the automated device assembles the buttons, the buttons need to be positioned and fixed with a jig plate for button transfer and feeding. Since the buttons are snap-connected to the jig plate, it is inconvenient for the machine to pick up the buttons. The buttons need to be de-mated from the jig plate before they can be taken down. At the same time, it is also necessary to ensure that the position of the buttons does not change, otherwise it will affect subsequent assembly. There is currently no device that can solve the above problems. Content of the Utility Model

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 shown, a preferred embodiment of the present invention proposes a key automatic material taking device, which mainly includes two parts: a blanking unit 1 and a material taking unit 2. The blanking unit 1 is used to clamp and position the fixture plate 3 and push the key 4 on the fixture plate 3 upward out of the fixture plate 3, and the material taking unit 2 will suck the key 4 and transfer it to the designated station.

[0026] As Figure 2 、 Figure 3 shown, the blanking unit 1 is located below the material taking unit 2. The blanking unit 1 is composed of components such as a bottom plate 11, a bearing plate 12, a driving mechanism 13 and a pressing block 16. Among them, the bearing plate 12 is located above the bottom plate 11 and is used to carry the fixture plate 3 and position the fixture plate 3. The bearing plate 12 and the bottom plate 11 are connected by four support rods, and the driving mechanism 13 is vertically installed and fixed on the bottom plate 11.

[0027] In this embodiment, the driving mechanism 13 is a cylinder, the output end of which is connected to two top blocks 18, and the cylinder can drive the two top blocks 18 to lift upward, so as to push the button 4 on the jig plate 3 out of the jig plate 3, so that the material taking unit 2 can take the material. An avoidance hole is provided on the carrier plate 12, and the top block 18 can pass through the avoidance hole to push the button 4 on the jig plate 3 out of the jig plate 3.

[0028] Two limiting posts 19 are arranged on each top block 18, and the two limiting posts 19 are arranged according to the outer contour of the key 4, so as to limit the key 4 on the jig plate 3, so that when the top block 18 pushes the key 4 out of the jig plate 3, the key 4 will not deviate, so that the material taking unit 2 can accurately suck the key 4. The number of limiting posts 19 can be adjusted according to the limiting requirements of the key 4.

[0029] refer to Figure 2 , a slide rail is provided on each side of the bottom of the carrier plate 12, and a clamping cylinder 17 is provided on one side of the bottom of the carrier plate 12. A sliding connecting plate 14 is slidably connected to both ends of the slide rail, and both ends of the sliding connecting plate 14 are slidably connected to the two slide rails, respectively, to ensure that the sliding connecting plate 14 can slide stably. A fixed plate 15 is vertically fixed on each sliding connecting plate 14, and a pressure block 16 is horizontally fixed on the top of the fixed plate 15. The tail end of the clamping cylinder 17 is fixedly connected to the bottom of one of the sliding connecting plates 14 through a connecting piece, and the output end is connected to the other sliding connecting plate 14. When the clamping cylinder 17 is working, under the action of the mutual force, the two sliding connecting plates 14 can move synchronously toward or away from each other, thereby driving the two pressure blocks 16 to move and clamp the shoulders on both sides of the fixture plate 3.

[0030] refer to Figure 4 The opposite sides of the two pressing blocks 16 are protruded outward to form a pressing portion 161. When the two pressing blocks 16 clamp the two sides of the jig plate 3, the pressing portion 161 can just abut against the top surface of the jig plate 3, and buckle the jig plate 3 on the supporting plate 12, preventing the jig plate 3 from moving upward when the top block 18 lifts the button 4 upward.

[0031] like Figure 3 As shown, an avoidance groove is provided at each end of the carrying plate 12 so that the two fixing plates 15 can move toward the direction of the fixture plate 3 at the center of the carrying plate 12 .

[0032] On the carrier plate 12, at each position of the jig plate 3, a positioning block 20 is provided, which can be inserted into the positioning hole at the bottom of the jig plate 3 to position the jig plate 3. When the jig plate 3 is positioned, the two pressing blocks 16 will move toward each other to press the jig plate 3. Then the ejector block 18 will move upward to eject the button 4 out of the jig plate 3.

[0033] As Figure 5 , Figure 6 shown, the component picking unit 2 is composed of components such as a component picking robot 21, a rotary joint 22, a lifting cylinder 23, a mounting plate 24, and a suction plate 25. The upper end of the rotary joint 22 is connected to the component picking robot 21, and the lower end is connected to the lifting cylinder 23. The component picking robot 21 can control the rotation of the rotary joint 22 to adjust the position of the suction plate 25. The output end of the lifting cylinder 23 is connected to the mounting plate 24. The suction plate 25 is located below the mounting plate 24 and is connected to the mounting plate 24 through a guide rod 27. The lower end of the guide rod 27 is fixed on the suction plate 25, and the upper end is slidably connected to the mounting plate 24 up and down.

[0034] A buffer spring 26 is arranged between the suction plate 25 and the mounting plate 24, and the buffer spring 26 plays a buffering role. In this embodiment, limiting grooves are respectively formed on the opposite surfaces of the suction plate 25 and the mounting plate 24, and the upper and lower ends of the buffer spring 26 are respectively received in the two limiting grooves.

[0035] In other technical solutions, the buffer spring 26 can also be sleeved on the guide rod 27 and can also play a buffering role.

[0036] Referring to Figure 7 , several type grooves 251 whose shapes are consistent with the outer shape of the button 4 are formed on the bottom surface of the suction plate 25, and a plurality of suction holes 252 are respectively arranged in the type grooves 251. The suction holes 252 are connected to an external air source. When the lifting cylinder 23 controls the mounting plate 24 to move downward, the suction plate 25 will also move downward accordingly. The suction plate 25 reaches above the jig plate 3 and contacts the jig plate 3. The buffer spring 26 can play a buffering role to prevent the suction plate 25 from pressing the button and damaging it.

[0037] The type grooves 251 will correspond to the positions of the buttons 4 on the jig plate 3. Then, the top block 18 will push the buttons 4 out of the jig plate 3, and the buttons 4 will be pushed into the type grooves 251. The suction holes 252 will extract air to generate negative pressure and firmly suck the buttons 4. Finally, the component picking robot 21 will transfer the buttons 4 to the designated workstations.

[0038] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that those skilled in the art may make to some parts thereof all reflect the principles of the present invention and fall within the protection scope of the present invention.
