[0036] Refer Figure 2 And in combination with Figure 3As shown, the material storage device 200 includes a number of first material placement components. The first material placement component includes two first limit blocks 201 and a first guide block 202 located between the first limit blocks 201. The first limit block 201 is fixedly installed with the first support 700. The first guide block 202 is located between the two first limit blocks 201 and can move up and down. The first guide block 202 is used to sleeved the first balance bar 100'. There is a first gap between the first limit block 201 and the first guide block 202 for the first balance bar 100' to move up and down. First grooves 203 for accommodating part of the first balance bar 100' are provided on the opposite side walls of the two first limit blocks 201, and the first balance bar 100' can move up and down along the first grooves 203.

[0037] In this embodiment, the first balance bar 100' is a square frame balance bar. The two ends of the first balance bar 100' respectively extend into the corresponding first grooves 203. First ridges 2031 are provided in the first grooves 203 on both sides, and the first ridges 2031 are in contact with the ends of the first balance bar 100'.

[0038] Furthermore, the first material placement component further includes a first counterweight 208 sleeved on the first guide block 202.

The first counterweight 208 is used to press the first balance bar 100' so that the first balance bar 100' can effectively discharge materials.

[0039] Refer Figure 2 and in combination with Figure 3 As shown, the material storage device 200 includes a number of second material placement components. The second material placement component includes two second limit blocks 204 and a second guide block 205 located between the second limit blocks 204. The second limit block 204 is fixedly installed with the first support 700. The second guide block 205 is located between the two second limit blocks 204 and can move up and down. The second guide block 205 is used to sleeved the second balance bar 200'. There is a second gap between the second limit block 204 and the second guide block 205 for the second balance bar 200' to move up and down. Second grooves 206 are provided on the opposite side walls of the two second limit blocks 204, and two second grooves 206 are arranged side by side on the side wall of each second limit block 204. By providing two pairs of second grooves 206, two second balance bars 200' can be placed simultaneously. The two second grooves 206 are separated by a barrier strip 210. The second grooves 206 are used to accommodate part of the second balance bar 200' and the second balance bar 200' can move up and down along the second grooves 206.

[0040] In this embodiment, the second balance bar 200' is a C-shaped balance bar, and two are sleeved on the second guide block 205 at the same time. The second balance bar 200' includes a connecting portion 201', and a first bending portion 202' and a second bending portion 203' formed by secondary bending at both ends of the connecting portion 201' respectively. Part of the connecting portion 201', the first bending portion 202', and the second bending portion 203' form a bent end portion extending into the corresponding second groove 206. A second rib 2061 is provided in each second groove 206, and the second rib 2061 abuts against the first bending portion 202'.

[0041] As shown in Figure 3 , on the side walls of the second guide block 205 opposite to the second limiting block 204, third grooves 207 for accommodating the end portions of the two second balance bars 200' are provided, and the second balance bars 200' can move up and down along the third grooves 207. The two second balance bars 200' are symmetrically placed. By providing the third grooves 207, two protruding portions 2051 are formed at the end of the second guide block 205. The protruding portions 2051 can extend into the corresponding second grooves 206. At the same time, the barrier strip 210 for forming the two second grooves 206 extends into the third groove 207. The second bending portions 203' of the two second balance bars 200' respectively abut against both sides of the barrier strip 210. Third ribs 2052 for abutting against the connecting portion 201', the first bending portion 202', and the second bending portion 203' are provided on three side walls of the protruding portion 2051.

[0042] Further, as shown in Figure 2 , the second material placement assembly further includes a second counterweight 209 sleeved on the second guide block 205. The second balance bars 200' are sleeved on the second guide block 205 one by one. The second counterweight 209 is used to press the second balance bars 200' so that the second balance bars 200' can effectively discharge materials.

[0043] In this embodiment, the discharge of the square frame balance bar and the C-shaped balance bar can be carried out simultaneously. Of course, in other embodiments, the discharge of the square frame balance bar or the C-shaped balance bar can also be carried out separately, and only the corresponding device needs to be reduced.

[0044] As shown in Figure 4 and in combination with Figure 5As shown in the figure, since the blanking of two types of balance rods, namely the first balance rod 100' and the second balance rod 200', is required, two blocking devices 300 are correspondingly arranged below the first material placement assembly and the second material placement assembly respectively. And because the sizes of the first balance rod 100' and the second balance rod 200' are different, the components of the two blocking devices 300 only differ in size, and their operating principles and component compositions are the same. Here, they are summarized as the same type for description. The blocking device 300 includes a first air cylinder 301, a first baffle 302, and a second baffle 303. The first baffle 302 and the second baffle 303 are horizontally arranged. A first guiding hole 3021 is provided on the first baffle 302, and a second guiding hole 3031 is provided on the second baffle 303. The first baffle 302 or the second baffle 303 is fixedly installed with the body of the first air cylinder 301 or the telescopic rod of the first air cylinder 301. In this embodiment, the first baffle 302 is fixedly installed with the body of the first air cylinder 301, and the second baffle 303 is fixedly installed with the telescopic rod of the first air cylinder 301.

[0045] In this embodiment, the first baffle 302 has a first blocking portion 3022, and the second baffle 303 has a second blocking portion 3032. The first blocking portion 3022 and the second blocking portion 3032 are respectively movably arranged below the two ends of the balance rod. The first blocking portion 3022 and the second blocking portion 3032 approach or separate under the drive of the first air cylinder 301 to block or release the balance rod in the storage device 200.

[0046] At the same time, a third limit block 304 that is cooperatively installed with the first guiding hole 3021 and a fourth limit block 305 that is cooperatively installed with the second guiding hole 3031 are installed on the first bracket 700. The third limit block 304 includes a first fixing portion that passes through the first guiding hole 3021 along the first direction and a first protruding portion that is installed on the first fixing portion and is used to support the first baffle 302. The first direction is the y-axis direction. The fourth limit block 305 includes a second fixing portion that passes through the second guiding hole 3031 along the first direction and a second protruding portion that is installed on the second fixing portion and is used to support the second baffle 303. The support for the first baffle 302 is formed by the first protruding portion, and the support for the second baffle 303 is formed by the second protruding portion, preventing the first baffle 302 and the second baffle 303 from falling. At the same time, the setting of the first guiding hole 3021 and the first fixing portion and the setting of the second guiding hole 3031 and the second fixing portion limit the opening and closing degree of the first blocking portion 3022 and the second blocking portion 3032.

[0047] In this embodiment, the first cylinder 301 first pushes the second baffle 303 to move, so that the second blocking portion 3032 moves away from the first blocking portion 3022, and under the restriction of the fourth limiting block 305, a force acting on the first baffle 302 is formed, so that the first blocking portion 3022 moves away from the second blocking portion 3032, thereby expanding the distance between the first blocking portion 3022 and the second blocking portion 3032, and finally completing the blanking of the balance bar.

[0048] As shown Figure 6 in the figure, a first chamfer 2021 is provided on the first guide block 202. The first chamfer 2021 is located at both ends of the bottom of the first guide block 202 close to the first limiting block 201. The first guide block 202 is provided with a first chamfer 2021 along the side wall opposite to each first limiting block 201 in the direction towards the bottom. A second chamfer 2053 is provided on the second guide block 205. The second chamfer 2053 is located at both ends of the bottom of the second guide block 205 close to the second limiting block 204. The second guide block 205 is provided with a second chamfer 2053 along the side wall opposite to each second limiting block 204 in the direction towards the bottom.

[0049] It should be noted that in this embodiment, the corresponding first blocking portion 3022 and second blocking portion 3032 are not only used to block the blanking of the first balance bar 100' and the second balance bar 200', but also used to support the first guide block 202 and the second guide block 205. When the opening degree of the first blocking portion 3022 and the second blocking portion 3032 becomes larger, the lowermost first balance bar 100' and second balance bar 200', as well as the first guide block 202 and the second guide block 205, all fall. After one first balance bar 100' and second balance bar 200' fall, the opening degree of the first blocking portion 3022 and the second blocking portion 3032 becomes smaller, thereby preventing the subsequent first balance bar 100' and second balance bar 200' from falling. At the same time, due to the setting of the first chamfer 2021 and the second chamfer 2053, when the opening degree of the first blocking portion 3022 and the second blocking portion 3032 becomes smaller, the first blocking portion 3022 and the second blocking portion 3032 press the first chamfer 2021 and the second chamfer 2053, and thus lift the first guide block 202 and the second guide block 205 again. The first guide block 202 and the second guide block 205 are made of lightweight materials such as aluminum to facilitate being lifted by the blocking device 300.

[0050] As shown Figure 7As shown, the feeding device 400 includes a conveying cylinder 401 installed on the machine table 100, a conveying platform 402 installed in cooperation with the conveying cylinder 401, a first guide rail 403 installed on the machine table 100, and a first slider 404 installed between the first guide rail 403 and the conveying platform 402. One or more placement grooves 4021 for receiving balance bars are provided on the conveying platform 402. The conveying cylinder 401 is used to drive the conveying platform 402 to move linearly back and forth. In this embodiment, since it is necessary to convey the first balance bar 100' and the second balance bar 200', two placement grooves 4021 are provided, and magnets are installed at the bottom of the placement grooves 4021 to assist in positioning the balance bars by attracting the balance bars with the magnets. Every time a first balance bar 100' and a second balance bar 200' fall into the corresponding placement groove 4021, the conveying cylinder 401 drives the conveying platform 402 to move to the material taking and pressing device 600 for the next step of assembling the keycap and the balance bar.

[0051] Refer Figure 8 As shown, the material taking and pressing device 600 includes a driving cylinder 601 installed on the second bracket 800, a positioning bracket 602 slidably installed on the second bracket 800 along the second direction, a material taking member 603 installed in the positioning bracket 602 and capable of extending out of the positioning bracket 602 or retracting into the positioning bracket 602 along the first direction, a material taking cylinder 604 installed on the second bracket 800, and one or more pressing cylinders 605 installed on the second bracket 800. The positioning bracket 602 is installed in cooperation with the telescopic rod of the driving cylinder 601. The driving cylinder 601 is used to drive the positioning bracket 602 to slide along the second direction. A plurality of material taking members 603 are provided corresponding to the pressing cylinders 605 and the material taking cylinder 604. The telescopic rods of the material taking cylinder 604 and the pressing cylinders 605 can extend to push or retract away from the corresponding material taking members 603. The material taking cylinder 604 is used to push the corresponding material taking member 603 to take the keycap, and the pressing cylinder 605 is used to push the corresponding material taking member 603 to press the keycap and the balance bar together. The first direction is the y-axis direction, and the second direction is the x-axis direction. In this embodiment, two pressing cylinders 605 are provided to simultaneously press two keycaps with the corresponding first balance bar 100' and second balance bar 200', and three material taking members 603 are provided corresponding to one material taking cylinder 604 and two pressing cylinders 605.

[0052] Refer Figure 9 And in combination with Figure 10As shown, the material picking component 603 includes a main body 6031, a plurality of air guide channels 6032 opened at the bottom of the main body 6031, and an elastic member 6033 installed on the main body 6031. The air guide channels 6032 are connected to an external air source device. Two to four air guide channels 6032 are provided. An air nozzle 6034 connected to the external air source device is installed on the side wall of the main body 6031. The air guide channels 6032 are interconnected in the main body 6031 and are also connected to the air nozzle 6034. Two elastic members 6033 are provided and are respectively installed at both ends of the main body 6031. The elastic member 6033 is a spring or a block-shaped object made of rubber.

[0053] Furthermore, a fourth groove 6035 is provided at the top of the main body 6031, and the bottom of the fourth groove 6035 is an arc surface. The telescopic rods of the material taking cylinder 604 and the pressing cylinder 605 can be extended into the corresponding fourth groove 6035 to drive the corresponding material taking member 603 to descend.

[0054] Furthermore, a plurality of positioning blocks 6036 are installed at the bottom of the body 6031 , and the positioning blocks 6036 are arranged at the bottom of the body 6031 to form a placement area 6037 for the keycaps. The air guide channel 6032 is arranged in the placement area 6037 , and the keycaps are sucked in by air drawn by an external air source and in cooperation with the air guide channel 6032 .

[0055] Ginseng Figure 11 Combined with Figure 12 As shown, the positioning bracket 602 is provided with a channel 6021 and a limiting groove 6022, and three channels 6021 are provided. The channel 6021 penetrates the positioning bracket 602 along a first direction, and the channel 6021 is used to accommodate the main body 6031 so that the main body 6031 can move along the first direction. The limiting groove 6022 is connected to the channel 6021, and each channel 6022 is correspondingly provided with two limiting grooves 6022, and the two limiting grooves 6022 are respectively located on both sides of the channel 6021. The limiting groove 6022 is used to accommodate the elastic member 6033 so that the elastic member 6033 can move along the first direction. After the main body 6031 and the elastic member 6033 descend, the elastic member 6033 is compressed when it contacts the bottom of the limiting groove 6022, and then rebounds to realize the reset of the main body 6031.

[0056] Ginseng Figure 13 Combined with Figure 8 As shown, the material table 500 is located below the material taking cylinder 604 , and is provided with a material slot 501 for placing key caps and a plurality of positioning slots 502 located around the material slot 501 and used to accommodate corresponding positioning blocks 6036 .

[0057] In this embodiment, an operator or an external device places the keycap in the material chute 501. After the first balance bar 100' and the second balance bar 200' enter the corresponding placement grooves 4021, the conveying cylinder 401 drives the conveying platform 402 to move to the picking and pressing device 600. At this time, there are picking members 603 below both the picking cylinder 604 and the pressing cylinder 605. The telescopic rod of the picking cylinder 604 extends and drives the corresponding picking member 603 to descend to pick up the keycap in the material chute 501. The telescopic rod of the picking cylinder 604 retracts, and the driving cylinder 601 drives the positioning bracket 602 together with the picking member 603 to move, moving the picking member 603 sucking the keycap above the first balance bar 100' or the second balance bar 200'. The telescopic rod of the pressing cylinder 605 located above the first balance bar 100' or the second balance bar 200' extends and drives the corresponding picking member 603 to descend, placing the keycap on the first balance bar 100' or the second balance bar 200'.
