[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a PLC fully automatic tapping machine, including a worktable 1, a robotic arm 4, a PLC controller 5, a tapping drill bit 6, and a material pushing and collecting device 3. Several support columns 2 are fixedly connected to the lower surface of the worktable 1. The robotic arm 4 is installed on the upper surface of the worktable 1. The PLC controller 5 is installed on the robotic arm 4. The tapping drill bit 6 is installed on the robotic arm 4. The material pushing and collecting device 3 is located on the worktable 1.

[0033] The specific setup and function of its material pushing and collecting device 3 will be explained below.

[0034] Example 1: Refer to Figure 2As shown in this embodiment: the material pushing and collecting device 3 includes a material pushing assembly 31 and a collecting assembly 32. The material pushing assembly 31 includes a fixing plate 3101, one side of which is fixedly connected to one side of the workbench 1. A fixing ring 3102 is fixedly connected to the upper surface of the fixing plate 3101, and an electric push rod 3103 is fixedly connected to the inner wall of the fixing ring 3102. A top plate 3104 is fixedly connected to the output end of the electric push rod 3103. The collecting assembly 32 includes a support plate 3201, which is fixed to the side of the workbench 1 away from the fixing plate 3101. A collecting box 3202 is placed on the upper surface of the support plate 3201, and a fixing seat 3203 is fixedly connected to one side of the collecting box 3202. The inner wall of the fixing seat 3203 rotates... The device includes a connecting plate 3204, a sloping plate 3214 fixedly connected to the bottom of the inner wall of the storage box 3202, and a reinforcing rib 3218 fixedly connected to the lower surface of the support plate 3201. By setting up the material pushing and storage device 3, after the PLC fully automatic tapping machine finishes tapping the machined sheet metal, it can easily push the sheet metal placed on the workbench 1 into the storage box, facilitating the unified collection of the sheet metal. The storage component 32 also includes a disc 3205, which is rotatably mounted on one side of the fixed base 3203. One end of the disc 3205 is fixedly connected to the connecting plate 3204. A connecting plate 3206 is rotatably connected to the centrifugal position of the disc 3205 away from the fixed base 3203. The connecting plate 3206 is located away from the disc 3204. A drive plate 3207 is rotatably connected to one side of the storage box 3202. A lead screw 3208 is threaded through one side of the drive plate 3207. A welding plate 3209 is fixedly connected to one side of the storage box 3202. One side of the welding plate 3209 is rotatably connected to the lead screw 3208. The rotating turntable 3210 drives the lead screw 3208 to rotate, which in turn drives the drive plate 3207. The drive plate 3207 drives the connecting plate 3206, which in turn drives the turntable 3210 to rotate. The turntable 3210 drives the connecting plate 3204, thus allowing the connecting plate 3204 to rotate along the inner wall of the fixed seat 3203. The turntable 3210 is rotatably connected to the side of the welding plate 3209. The cross-section of the turntable 3210 is "T" shaped. One end of the turntable 3210 is fixedly connected to one end of the lead screw 3208. Rotating the turntable 3210 can drive the lead screw 3208 to rotate, thus achieving the effect of convenient control of the lead screw 3208. A sliding hole 3212 is provided on the side of the fixed seat 3203 away from the turntable 3210. The center of the sliding hole 3212 is coaxial with the axis of rotation of the connecting plate 3204. A sliding rod 3213 is slidably connected to the inner wall of the sliding hole 3212. One end of the sliding rod 3213 is fixedly connected to one side of the connecting plate 3204. During the rotation of the connecting plate 3204 along the inner wall of the fixed seat 3203, the sliding rod 3213 fixed on the connecting plate 3204 will rotate along the inner wall of the sliding hole 3212, thus improving the stability of the connecting plate 3204 during rotation.

[0035] Example 2: Several anti-slip patterns 3211 are formed on one side of the connecting plate 3204. The anti-slip patterns 3211 are evenly distributed on one side of the connecting plate 3204. The anti-slip patterns 3211 can increase the friction on one side of the connecting plate 3204, thereby preventing the punched vehicle sheet from sliding too fast on the connecting plate 3204 and hitting the storage box 3202, causing damage. A handle 3215 is fixedly connected to the side of the storage box 3202 away from the fixed seat 3203. The handle 3215 has a "U" shaped cross-section. The handle 3215 can drive the storage box 3202, achieving the effect of convenient control of the storage box 3202. The lower surface of the storage box 3202 is fixedly connected to the positioning block 3216. The surface of the support plate 3201 is provided with a positioning hole 3217. The positioning hole 3217 is adapted to the size of the positioning block 3216. When placing the storage box 3202, the positioning block 3216 on the storage box 3202 can be inserted into the positioning hole 3217, achieving the effect of making the storage box 3202 more stable.

[0036] When using the PLC fully automatic tapping machine to tap and drill automotive sheet metal, first place the sheet metal to be processed on the worktable 1, then use a clamp to hold and limit its position. Next, start the robotic arm 4 to drive the tapping drill bit 6 to tap the sheet metal. After the automotive sheet metal is processed and needs to be pushed and stored, first start the electric actuator 3103 to drive the top plate 3104, causing the top plate 3104 to push the processed automotive sheet metal towards the storage box 3202. At this time, the automotive sheet metal will move onto the connecting plate 3204 as the top plate 3104 pushes it, and then fall into the storage box 3202. Repeat the above steps on the inner wall of 02. After the vehicle sheet metal, which has been tapped and processed, is filled in the storage box 3202, rotate the turntable 3210 to drive the lead screw 3208 to rotate. The lead screw 3208 drives the drive plate 3207, the drive plate 3207 drives the connecting plate 3206, the connecting plate 3206 drives the turntable 3210 to rotate, and the turntable 3210 drives the connecting plate 3204. This allows the connecting plate 3204 to rotate along the inner wall of the fixed seat 3203. When the connecting plate 3204 blocks the opening on one side of the storage box 3202, move the handle 3215 to drive the storage box 3202, causing the storage box 3202 to move the positioning block and the positioning hole 3217 to separate. Afterwards, the processed vehicle body panels can be transferred to the designated location using the storage box 3202. Once the transfer is complete, move the handle 3215 to move the empty storage box 3202 and place it on the support plate 3201. Simultaneously, insert the positioning block on the storage box 3202 into the positioning hole 3217 to ensure a more stable placement of the storage box 3202. After the storage box 3202 is securely placed, rotate the turntable 3210 in the reverse direction to rotate the lead screw 3208. The lead screw 3208 drives the drive plate 3207, which in turn drives the connecting plate 3206. The connecting plate 3206 then drives the turntable 3210 to rotate. 10 drives the connecting plate 3204, which in turn allows the connecting plate 3204 to rotate in the opposite direction along the inner wall of the fixed seat 3203 until one side of the connecting plate 3204 is in contact with the worktable 1. During the rotation of the connecting plate 3204 along the inner wall of the fixed seat 3203, the slide rod 3213 fixed on the connecting plate 3204 will rotate along the inner wall of the slide hole 3212, which improves the stability of the connecting plate 3204 during rotation. In addition, the anti-slip texture 3211 can increase the friction on one side of the connecting plate 3204, thereby preventing the punched vehicle sheet from sliding too fast on the connecting plate 3204 and hitting the storage box 3202 and causing damage.
