[0033] Specifically, in this embodiment, the first conveying unit includes a rotating table 13 for carrying a product carrier and an indicating device 15 installed on a frame 17 for displaying the rotation angle of the rotating table 13. The rotating table 13 is connected to the servo motor and rotates half a circle. The indicating device 15 includes an indicator light. After the rotating table 13 rotates to the right position, the indicator light comes on. Only then will the grasping component 2 come over to pick up and place the workpiece. Manual picking and placing operations at the loading and unloading positions can also be performed. If the rotating table 13 does not rotate to the right position, the indicating device 15 will alarm.

[0034] Specifically, in this embodiment, the loading component 1 also includes a first detection device 16 installed on the side of the rotating table 13 for detecting whether there is a workpiece on the product carrier. The first detection device 16 is fixed on the frame 17. The first detection device 16 mainly adopts visual detection technology. The first detection device 16 includes a high-definition camera installed on the frame 17, which is used to take real-time photos of the product carrier area. When the grasping component 2 takes the workpiece on the product carrier, the first detection device 16 transmits a signal, and the servo motor drives the rotating table 13 to rotate.

[0035] Specifically, in this embodiment, two product carriers are installed and are symmetrically arranged about the rotation center of the turntable 13. The product carriers are specifically a fixed plate installed on the turntable and a first fixture 14 installed on the fixed plate for fixing the workpiece. There are multiple first fixtures 14, which are symmetrically arranged about the rotation center of the turntable 13.

The clamp 22 is installed on the grasping frame and is symmetrically arranged about the grasping frame. A plurality of clamps 22 are installed on one side of the grasping frame, corresponding to the number of the first fixture 14, for grasping the workpiece to be processed. The clamp 22 on the other side of the grasping frame is used to grasp the workpiece after processing. The clamp 22 is also provided with an anti-slip strip 26 for preventing the workpiece from falling during the grasping process.

[0039] Specifically, in this embodiment, a blowing mechanism 25 is installed on the side of the clamp 22 for cleaning the limit assembly 3. After the CNC machine tool 4 completes processing, debris will remain on the outer periphery of the limit assembly 3. The blowing mechanism 25 cleans the debris to ensure that the next product can be smoothly placed and positioned.

[0040] Specifically, in this embodiment, the gripping assembly 2 also includes a clamping mechanism 23 installed on the top of the clamping jaw 22 for fixing the workpiece in the limiting assembly 3. The clamping mechanism 23 is installed on the top of the clamping jaw 22. When the clamping jaw 22 moves the workpiece from the gripping position to the limiting assembly 3, the clamping mechanism 23 applies pressure to the workpiece to fix the workpiece on the limiting assembly 3.

[0041] Specifically, in this embodiment, the grasping assembly 2 also includes a second detection device 24 installed on the side of the clamp 22 for detecting whether there is a workpiece on the clamp 22. After the clamp 22 grasps the workpiece from the grasping position, the second detection device 24 detects whether the workpiece is on the clamp 22. If there is no workpiece on the clamp 22, the second detection device 24 will alarm. The second detection device 24 is specifically a contact sensor installed on the side of the clamp 22. When the clamp 22 grasps the workpiece and transports it to the limit assembly 3, if the workpiece does not contact the second detection device 24, the second detection device 24 will alarm.

[0042] Specifically, in this embodiment, the limiting assembly 3 includes a second fixture 31 fixed on the CNC machine tool 4 for fixing the workpiece, and the number of the second fixture 31 corresponds to the number of the clamping jaws 22 and the first fixture 14 .

[0043] Specifically, in this embodiment, the number of the second fixtures 31 is four, and the arrangement is two rows and two columns. The specific shape of the second fixture 31 is cylindrical, and a slot for fixing the workpiece is installed on the cylinder. The clamping mechanism 23 is used to fix the workpiece in the slot. After the fixation is completed, the CNC machine tool 4 is started to process the workpiece.

[0044] Specifically, in this embodiment, a plurality of CNC machine tools 4 may be installed, and the grabbing assembly 2 may sequentially convey workpieces to be processed into the plurality of CNC machine tools 4 and grab the processed workpieces.

[0045] The specific workflow of the above-mentioned insert implantation equipment and injection molding machine may include the following operations:

[0046] Step 1: The staff places the workpiece in the four first fixtures 14 on the rotating table 13 .

[0047] Step 2: After starting the equipment, the equipment automatically transfers the four workpieces to be processed to the grabbing position, and simultaneously transfers the finished products at the grabbing position to the loading and unloading position.

[0048] Step 3: The grabbing assembly 2 grabs the workpiece from the grabbing position, and then puts the processed four workpieces back into the first fixture 14 .

[0049] Step 4: The grabbing component 2 confirms the need to enter the CNC machine tool 4 to grab the product according to the completion status of the CNC machine tool 4.

[0050] Step 5: The grabbing assembly 2 enters the CNC machine tool 4 and grabs the finished product out of the second fixture 31 .

[0051] Step 6: The grabbing component 2 moves to the limiting component 3, and blows air to the second fixture 31 along a circular trajectory to blow away the machining chips remaining on the second fixture 31.

[0052] Step 7: After the grabbing assembly 2 rotates, the four workpieces to be processed are placed into the second fixture 31 and pressed twice to ensure that the products are placed in place.

[0053] Step 8: The grabbing component 2 is connected to the CNC machine tool 4 for communication. After the CNC machine tool 4 completes processing, the grabbing component 2 moves to the grabbing position of the loading component 1, first grabs the workpiece to be processed from the first fixture 14, and then puts the processed workpiece back into the first fixture 14, and repeats the cycle.
