In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0031] In one embodiment of this utility model, such as Figures 1-4As shown, a weighing device for pre- and post-molding includes a housing 1, a moving assembly, a weighing scale 3, a first lifting assembly 4, a second lifting assembly 5, a first placement seat 6, a second placement seat 7, a rotating lifting assembly 8, and a dust blowing assembly 9. The first placement seat 6 and the second placement seat 7 are respectively vertically and vertically mounted on the housing 1, and are also vertically and horizontally mounted on the housing 1. The first lifting assembly 4 drives the first placement seat 6 to move vertically, the second lifting assembly 5 drives the second placement seat 7 to move vertically, and the moving assembly drives the first placement seat 6 and the second placement seat 7 to move horizontally and vertically synchronously. The weighing scale 3 is mounted on the housing 1 and is located below the first placement seat 6 and the second placement seat 7. The weighing scale 3 is used to weigh the amount of plastic injection molding on the workpiece.The dust blowing component 9 is installed on the rotary lifting component 8. The dust blowing component 9 is used to blow away the dust on the second placement seat 7. The rotary lifting component 8 is used to drive the dust blowing component 9 to rotate or move up and down. In this embodiment, the moving component is movably installed inside the housing 1. The moving component is equipped with the first lifting component 4 and the second lifting component 5. The first lifting component 4 and the second lifting component 5 have the same structure. The first lifting component 4 is located behind the second lifting component 5. The output end of the first lifting component 4 is respectively equipped with the first placement seat 6, and the output end of the second lifting component 5 is respectively equipped with the second placement seat 7. The first placement seat 6 is located behind the second placement seat 7. The rotary lifting component 8 is installed on the housing 1, and the dust blowing component 9 is installed at the output end of the rotary lifting component 8. During operation, the dust blowing component 9... The moving component drives the first placement seat 6 and the second placement seat 7 to move forward synchronously, so that the first placement seat 6 moves directly above the weighing scale 3. Then, the external robotic arm places the workpiece to be encapsulated (specifically an inductor) onto the first placement seat 6. After placement, the first lifting component 4 drives the first placement seat 6 to descend until it is placed on the top surface of the weighing scale 3. Furthermore, after the first placement seat 6 is placed on the top surface of the weighing scale 3, the output end of the first lifting component 4 will continue to move downward a short distance, that is, the first lifting component 4 and the first placement seat 6 are not connected by force, so that the weighing scale 3 can accurately weigh. After weighing the workpiece placed on the first placement seat 6, an external robotic arm removes the workpiece from the first placement seat 6 and seals it. During the sealing process, the moving component drives the first placement seat 6 and the second placement seat 7 to move backward synchronously, so that the second placement seat 7 moves directly above the weighing scale 3. After moving into position, another external robotic arm places six nuts onto the second placement seat 7. After the nuts are placed, the rotating lifting component 8 drives the dust blowing component 9 to rotate above the second placement seat 7 and lower it to cover the dust blowing area. Then, the dust blowing component 9 blows out negative ion air for dust removal. After dust removal is completed, the rotating lifting component 8 drives the... After the dust blowing component 9 is reset, the external robot arm places the plastic-sealed workpiece onto the second placement seat 7. After placement, the second lifting component 5 drives the second placement seat 7 to move downward until the second placement seat 7 is placed on the top surface of the weighing scale 3. Similarly, the second lifting component 5 continues to move downward a short distance to ensure that the weighing scale 3 can accurately weigh the weight of the plastic-sealed workpiece. By comparing the weight before plastic sealing, the injection volume of the plastic seal can be obtained. It should be noted that the weights of the first placement seat 6, the second placement seat 7, and the multiple nuts placed on the second placement seat 7 are known. After weighing, the corresponding weights need to be subtracted to obtain the injection volume.This application utilizes a housing 1, a moving component, a weighing scale 3, a first lifting component 4, a second lifting component 5, a first placement seat 6, a second placement seat 7, a rotating lifting component 8, and a dust blowing component 9 to measure the injection volume by analyzing the weight change of the workpiece before and after molding. The weighing is accurate, convenient, and quick. Furthermore, the dust blowing component 9 employs negative ion airflow for dust removal, avoiding dust interference while simultaneously cleaning multiple nuts. This eliminates the need for subsequent dust removal and cleaning in assembly processes, making it convenient, fast, and improving production efficiency.
[0032] like Figures 1-2 As shown, the moving assembly includes a moving plate 21 and a first driving unit. The moving plate 21 is movably mounted inside the housing 1. The top surface of the moving plate 21 is equipped with a first lifting assembly 4 and a second lifting assembly 5. The first driving unit is used to drive the moving plate 21 to move back and forth. In this embodiment, the first driving unit is a cylinder. The first driving unit is installed inside the housing 1, and its output end is connected to the moving plate 21. When working, the output end of the first driving unit extends and retracts, causing the moving plate 21 to drive the first placement seat 6 and the second placement seat 7 to move back and forth through the first lifting assembly 4 and the second lifting assembly 5, respectively, which is convenient and quick.
[0033] like Figures 1-3As shown, the second lifting assembly 5 includes a support column 51, a support plate 52, a guide member 53, and a second driving part 54; the housing 1 is provided with a clearance groove 11, the second driving part 54 is installed on the top surface of the moving plate 21, one end of the support column 51 is connected to the output end of the second driving part 54, the other end of the support column 51 passes through the clearance groove 11 and is connected to the bottom surface of the support plate 52, the guide member 53 is installed on the top surface of the support plate 52, and the guide member 53 is movably installed on the second placement seat 7.

Two guide members 53 are respectively installed on the top surface of each support plate 52. The guide members 53 are movably installed on the second placement seat 7. During operation, after the workpiece is placed on the second placement seat 7, the two second driving units 54 drive the four support columns 51 to move downwards. 52 drives the second placement seat 7 to move downwards. At this time, the top surface of the support plate 52 abuts against the bottom surface of the second placement seat 7. After the second placement seat 7 is placed on the weighing scale 3, the support plate 52 drives the guide member 53 to continue moving downwards. At this time, the support plate 52 disengages from the second placement seat 6, and the guide member 53 moves downwards inside the second placement seat 7, but does not completely disengage. After the weighing is completed, the second driving part 54 drives the support column 51 to move upwards, so that the support plate 52 drives the guide member 53 to move upwards. The guide member 53 moves upwards inside the second placement seat 6 until the top surface of the support plate 52 is in contact with the bottom surface of the second placement seat 7, and the second placement seat 7 is lifted up, which is convenient and quick.
[0034] like Figures 1-3 As shown, the second placement seat 7 has second sliding sleeves 71 at its four corners, and the guide member 53 is slidably installed on the second sliding sleeves 71. In this embodiment, the guide member 53 is slidably installed inside the second sliding sleeve 71, which not only helps to ensure the smoothness of sliding and prevents jamming, but also plays a guiding role.
[0035] like Figure 3As shown, the second placement base 7 is provided with second positioning posts 72, third positioning posts 73, and height members 74. The height members 74 are located in the middle of the top surface of the second placement base 7. There are four second positioning posts 72, which are located at the four corners of the height members 74. There are two third positioning posts 73, which are located to the right of the second positioning posts 72. In this embodiment, during operation, an external robot arm places six nuts on the tops of the four second positioning posts 72 and the two third positioning posts 73. The top of the height members 74 is used to abut against the bottom of the sealed workpiece, thereby offsetting the height difference caused by the nuts. The second positioning posts 72 and the third positioning posts 73 can position the workpiece, ensuring the accuracy of the subsequent position of the nuts and the workpiece.
[0036] like Figure 4 As shown, the first placement seat 6 is provided with a first positioning post 61 and a first sliding sleeve 62. There are four first positioning posts 61 and four first sliding sleeves 62. The four first positioning posts 61 are used to position the workpiece before molding, and the four first sliding sleeves 62 are located at the four end corners of the first placement seat 6. In this embodiment, the four first positioning posts 61 are used to position the workpiece before molding, and the four first sliding sleeves 62 correspond to the guide members of the first lifting assembly 4.
[0037] like Figures 1-2As shown, the rotary lifting assembly 8 includes a first mounting base 81, a second mounting base 82, a third driving part 83, a fourth driving part 84, and a mounting rod 85. The first mounting base 81 is mounted on the top surface of the housing 1. The third driving part 83 is mounted on the first mounting base 81. The output end of the third driving part 83 is mounted on the second mounting base 82. The third driving part 83 is used to drive the second mounting base 82 to move up and down. The fourth driving part 84 is mounted on the second mounting base 82. One end of the mounting rod 85 is mounted on the output end of the fourth driving part 85. The other end of the mounting rod 85 is mounted on the dust blowing assembly 9. The fourth driving part 85 is used to drive the mounting rod 85 to rotate. In this embodiment, the third drive unit 83 is a cylinder, and the fourth drive unit 84 is a motor. When dust blowing is required, the second drive unit 83 drives the second mounting base 82 to move upward to prevent the subsequent mounting rod 85 from being too low and colliding with other components. After rising to the required height, the fourth drive unit 84 drives the mounting rod 85 to rotate, thereby moving the dust blowing assembly 9 directly above the second placement seat 7. After rotating to the correct position, the third drive unit 83 drives the second mounting base 82 to move downward, causing the dust blowing assembly 9 to move downward and cover the dust blowing area, specifically the area surrounded by four second positioning posts 72 and two third positioning posts 73. After descending to the correct position, the dust blowing assembly 9 blows out negative ion air to achieve dust removal. After dust blowing is completed, it resets, which is convenient and quick.
[0038] like Figures 1-2 As shown, the dust blowing assembly 9 includes a dust blowing hood 91, a fan 92, and an exhaust pipe 93. The dust blowing hood 91 is mounted on the mounting rod 53, and the fan 92 is mounted on top of the dust blowing hood 91.

In this embodiment, the fan 92 is a negative ion fan. When working, after the dust blowing hood 91 covers the dust blowing area of the second placement seat 7, the fan 92 begins to blow negative ion air into the interior of the dust blowing hood 91. Within the covered area, dust is blown up and discharged to the outside through the exhaust pipe 93, which is convenient and quick.
