[0031] Figure 1 This is a three-dimensional structural schematic diagram of the gate residual heat cutting device of this application. Figure 2 This is a structural schematic diagram of the translation mechanism, hot cutting mechanism, and locking and unloading mechanism of this application, as shown below. Figure 1 and Figure 2 As shown, the gate residue hot cutting device includes a conveying mechanism 11, a translation mechanism 12, a hot cutting mechanism 13, a locking and unloading mechanism 14, a first station and a second station. The hot cutting mechanism 13 is located at the first station, and the locking and unloading mechanism 14 is located at the second station. The conveying mechanism 11 passes through at least the second station. The translation mechanism 12 is configured to drive the hot cutting mechanism 13 to reciprocate between the first station and the second station. The hot cutting mechanism 13 is configured to receive the product 20 to be cut at the first station and to cut the gate residue of the product 20 at the second station. The locking and unloading mechanism 14 is configured to lock the product 20 to be cut at the second station.

[0032] When the locking and unloading mechanism 14 locks the product 20, the hot cutting mechanism 13 removes the gate residue of the product 20, the translation mechanism 12 drives the hot cutting mechanism 13 to reset to the first station, and the locking and unloading mechanism 14 releases the cut product 20 to the conveying mechanism 11.

[0033] The process for treating product 20 using the gate residue hot cutting device of this application is as follows:

[0034] Step 1: Use a robotic arm to place the product 20 to be cut onto the hot cutting mechanism 13 at the first station.

[0035] Step two: The translation mechanism 12 drives the hot cutting mechanism 13 to move to the second station;

[0036] Step 3: The locking and unloading mechanism 14 locks the product 20 to be cut in place;

[0037] Step 4: The hot cutting mechanism 13 removes the gate residue of product 20;

[0038] Step 5: The translation mechanism 12 drives the hot cutting mechanism 13 to move to the first station;

[0039] Step six: The locking and unloading mechanism 14 releases the cut product 20 to the conveying mechanism 11. In this embodiment, the first station is the loading station, and the second station is the cutting and unloading station.

[0040] Repeating the above steps will process multiple products 20.

[0041] The gate residual hot cutting device of this application completes the cutting and unloading of product 20 at the second station, integrating the existing cutting station and unloading station into one, which can reduce the length of the equipment and reduce the cost, and realize fully automated cutting and unloading, thereby improving production efficiency and saving labor costs.

[0042] Optionally, Figure 3 This is a schematic diagram of the heat-cutting mechanism of this application. Figure 4 yes Figure 3 The diagram shown is a schematic of the hot-cutting mechanism after removing multiple hot-cutting components, as follows: Figure 3 and Figure 4 As shown, the hot cutting mechanism 13 includes a base plate 131 and at least one hot cutting component 132. At least one fixture (not shown) is provided on the base plate 131, which carries the product 20 to be cut. The hot cutting component 132 is connected to the base plate 131, and the cutter 1326 of the hot cutting component 132 is correspondingly positioned with respect to the fixture. The output end of the translation mechanism 12 is connected to the base plate 131. When the end of the product 20 is positioned on the fixture, the cutter 1326 of the hot cutting component 132 aligns with the gate residue of the product 20. When the locking and unloading mechanism 14 locks the product 20 in place, the hot cutting component 132 drives the cutter 1326 to cut off the gate residue.

[0043] Optionally, such as Figure 4 As shown, the base plate 131 is provided with at least one mounting portion 1311, and the fixture is fixed to the mounting portion 1311. At least one drop hole 101 is provided on the periphery of the mounting portion 1311, penetrating the base plate 131. The cut-off gate residue falls through the drop hole 101 to the conveying mechanism 11. In this embodiment, two drop holes 101 are provided on the periphery of the mounting portion 1311.

In this embodiment, the baffle frame 134 is used to prevent the cut-off gate residue from falling into the area outside the baffle frame 134, ensuring a clean working environment for the hot cutting assembly 132 and preventing gate residue from affecting the operation of the hot cutting assembly 132.

[0045] Optionally, Figure 5 This is a schematic diagram of the structure of the heat-cutting component of this application, as shown below. Figure 4 and Figure 5 As shown, the hot-cutting assembly 132 includes a base 1321 and a cutting driver 1322, a heat insulation pad 1323, a heating block 1324, a heating element 1325, and a cutter 1326 connected to the base 1321.

The cutter 1326 is movably connected to the heating block 1324, and the output end of the cutting driver 1322 is connected to the cutter 1326. The cutting driver 1322 is used to drive the cutter 1326 to extend and retract to remove the gate residue of the product 20. This application utilizes the heating element 1325 to heat the heating block 1324, thereby heating the cutter 1326. The heated cutter 1326 is used to cut the hard and brittle product 20 to ensure a relatively flat cut surface.

[0046] Alternatively, the cutting driver 1322 may be, for example, a cylinder or a hydraulic cylinder, but is not limited thereto.

[0047] Optionally, such as Figure 5 As shown, the hot-cutting assembly 132 also includes a temperature sensing wire 1327, which is at least partially installed in the heating block 1324. The temperature sensing wire 1327 is used to detect the temperature of the heating block 1324.

Depending on the material of the product 20, a corresponding temperature can be applied to the cutter 1326.

[0048] Optionally, such as Figure 5As shown, the heating block 1324 is provided with a sliding groove, and the cutter 1326 is at least partially disposed in the sliding groove. The hot cutting assembly 132 also includes a limiting member 1328, which is connected to the heating block 1324 and at least partially covers the cutter 1326.

At least two fixtures are provided on the base plate 131, and multiple hot cutting components 132 surround the periphery of each fixture. The two hot cutting components 132 between two adjacent fixtures are arranged side by side. In this embodiment, the two hot cutting components 132 between two adjacent fixtures are arranged side by side, which can make full use of the space on the base plate 131.

[0050] Optionally, such as Figure 3 and Figure 4 As shown, each fixture is surrounded by four hot-cutting components 132, which are capable of removing four gate residues from the product 20.

[0051] Optionally, Figure 6 This is a structural schematic diagram of the protective component and locking feeding mechanism of this application, as shown below. Figure 2 and Figure 6 As shown, the hot-cutting mechanism 13 also includes at least one protective member 133. The protective member 133 is fixed to the side of the base plate 131 near the second station. The protective member 133 is located at the second station and has an induction space 103. The product 20 released by the locking unloading mechanism 14 falls along the induction space 103 to the conveying mechanism 11. In this embodiment, the protective member 133 is used to prevent the product 20 from tilting in other directions and causing interference, ensuring that the product 20 can fall along the induction space 103 to the conveying mechanism 11.

[0052] Optionally, such as Figure 6As shown, the protective component 133 includes a first protective plate 1331, a second protective plate 1332, and a baffle 1333. The first protective plate 1331 and the second protective plate 1332 are disposed opposite to each other, and the baffle 1333 is connected between the first protective plate 1331 and the second protective plate 1332. The guiding space 103 is formed between the first protective plate 1331, the second protective plate 1332, and the baffle 1333. The ends of the first protective plate 1331 and the second protective plate 1332 are fixed to the base plate 131. In this embodiment, the first protective plate 1331 and the second protective plate 1332 block and limit the product 20 in the left and right directions, and the baffle 1333 blocks and limits the product 20 in the rear direction, ensuring that the product 20 can fall vertically to the conveying mechanism 11.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, the base plate 131 is located at the first station, and the protective component 133 is located at the second station. When the translation mechanism 12 drives the base plate 131 to move from the first station to the second station, the protective component 133 moves out of the second station synchronously with the base plate 131. When the translation mechanism 12 drives the base plate 131 to move from the second station to the first station, the protective component 133 moves to the second station synchronously with the base plate 131.

[0054] Optionally, such as Figure 1 and Figure 2 As shown, the bottom surface of the base plate 131 is provided with at least two guide blocks 135 and a connecting block 136.

One end of the lead screw is rotatably connected to the support frame 121, and the other end of the lead screw is connected to the translation driver 123. The translation driver 123 is fixed to the support frame 121 and drives the base plate 131 to move via the lead screw. In this embodiment, the translation driver 123 is, for example, a servo motor. The translation driver 123 is used to drive the lead screw to rotate in both directions, so that the base plate 131 reciprocates between a first station and a second station.

[0055] Optionally, such as Figure 2 and Figure 6As shown, the locking and unloading mechanism 14 includes a bracket 141, at least one lifting drive assembly 142, and at least one clamping drive assembly 143. The lifting drive assembly 142 is connected to the top of the bracket 141, and its output end is connected to the clamping drive assembly 143. The lifting drive assembly 142 drives the clamping drive assembly 143 to move vertically up and down. The clamping drive assembly 143 clamps and fixes the product 20 to be cut and releases the cut product 20. After the hot cutting mechanism 13 removes the gate residue of the product 20, the lifting drive assembly 142 drives the clamping drive assembly 143 and the product 20 to rise. Then, the translation mechanism 12 drives the hot cutting mechanism 13 to reset. Next, the lifting drive assembly 142 drives the clamping drive assembly 143 and the product 20 to fall down until a portion of the product 20 is in the induction space 103. Finally, the clamping drive assembly 143 releases the product 20, at which point the product 20 falls down along the induction space 103 to the conveying mechanism 11.

[0056] Optionally, the number of lifting drive assembly 142 and clamping drive assembly 143 corresponds to the number of fixtures on the base plate 131 that carry the product 20. When there are two fixtures on the base plate 131, the locking unloading mechanism 14 includes two lifting drive assemblies 142 and two clamping drive assemblies 143. That is, the gate residual hot cutting device can process two products 20 at a time, which is beneficial to improving the cutting efficiency.

[0057] Optionally, such as Figure 6 As shown, the bracket 141 includes two columns 1411 arranged opposite to each other and a crossbeam 1412 connected to the top of the two columns 1411. The lifting drive assembly 142 is fixed to the middle of the crossbeam 1412.

[0058] Optionally, such as Figure 6 As shown, the lifting drive assembly 142 includes a lifting driver 1421, a lifting plate 1422, a clamping member 1423, and a support 1424. The lifting driver 1421 is fixed on the bracket 141, and the output shaft of the lifting driver 1421 is connected to the lifting plate 1422. The clamping member 1423 and the support 1424 are fixed on one side of the lifting plate 1422, and the clamping member 1423 is located above the support 1424. The clamping drive assembly 143 is fixed on the support 1424. The lifting driver 1421 is used to drive the lifting plate 1422 to descend so that the clamping member 1423 presses against the end of the product 20. When the translation mechanism 12 drives the base plate 131 to move to the second station, the lifting driver 1421 drives the lifting plate 1422 to descend until the clamping member 1423 presses on the end of the product 20. At this time, the product 20 is fixed between the clamping member 1423 and the fixture, ensuring that the cutter 1326 of the hot cutting assembly 132 can smoothly cut the gate residue.

[0059] Optionally, the lifting drive 1421 may be, for example, one of a combination mechanism of a cylinder, a hydraulic cylinder, or a motor lead screw, but is not limited thereto.

The clamping driver 1431 is fixed to the support base 1424, and the two clamping arms 1432 are connected to the clamping driver 1431. The clamping driver 1431 is used to drive the two clamping arms 1432 to clamp or release the product 20. In this embodiment, the lifting driver 1421 is, for example, a cylinder or a hydraulic cylinder, but is not limited thereto.

[0061] Optionally, such as Figure 1 As shown, the conveying mechanism 11 includes a support platform 111 and a conveyor belt 112 and a conveying drive assembly (not shown) connected to the support platform 111. The translation mechanism 12, the hot cutting mechanism 13 and the locking and unloading mechanism 14 are all connected to the support platform 111. The conveyor belt 112 passes under the translation mechanism 12, the hot cutting mechanism 13 and the locking and unloading mechanism 14. The conveying drive assembly is used to drive the conveyor belt 112 to convey the product 20 and / or gate residue.

[0062] Optionally, the carrier frame 121 of the translation mechanism 12 is arranged across the conveyor belt 112, and the opposite sides of the carrier frame 121 are fixed on the support platform 111; the bracket 141 of the locking unloading mechanism 14 is arranged across the conveyor belt 112, and the two columns 1411 of the bracket 141 are fixed on the support platform 111.

[0063] Optionally, the gate residual hot cutting device also includes a control system 15, which is electrically connected to the conveying mechanism 11, the translation mechanism 12, the hot cutting mechanism 13, and the locking and unloading mechanism 14.
