The conveying module includes a conveying mounting plate and a conveying drive assembly fixedly mounted on the conveying mounting plate. Conveying rollers are mounted at the bottom of the conveying mounting plate, and the bottom frame includes roller sliding rails that match the conveying rollers. While this patent enables the back-and-forth movement of the jig disc, different specifications and / or shapes of the workpieces require different jig discs, and quick disassembly and replacement of the jig disc is not possible. Therefore, the shortcomings are significant, and a solution is urgently needed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic conveying device for hot pressing and unloading.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic hot-press unloading conveying device includes a base, two slide rails parallel to both sides of the base, a conveyor trolley slidably connected to the two slide rails, two racks mounted on both sides of the base and parallel to the slide rails, two gears rotatably connected to both ends of the conveyor trolley, a transmission rod connected to the two gears, a rotation drive mechanism mounted on the bottom surface of the conveyor trolley for driving the transmission rod to rotate, and a contouring carrier detachably mounted on the top surface of the conveyor trolley. The two slide rails are respectively arranged in a one-to-one correspondence with the two racks, and the two gears are respectively meshed with the two racks for transmission. At least two positioning pins are protruding from the top surface of the conveyor trolley. The bottom plate of the contouring carrier is provided with at least two positioning holes, with one positioning pin engaging with one positioning hole. At least one spring pin is provided on the top surface of the conveyor trolley, and at least one locking lug is mounted on the side of the bottom plate of the contouring carrier. The locking lug has a locking hole, and the pin shaft of the spring pin can be inserted into the locking hole.

[0007] Furthermore, the top surface of the transport vehicle is equipped with at least two support frames, with positioning posts located on the top surface of the support frames. The support frames are used to support the bottom plate of the modeling vehicle.

[0008] Furthermore, the bottom plate of the copying vehicle is provided with at least two adjustment slots, each adjustment slot having an adjustment block slidably connected therein, and a positioning hole is provided in one adjustment block. The adjustment block is locked to the bottom plate of the copying vehicle by a fastener.

[0009] Furthermore, the number of locking lugs is equal to the number of adjusting blocks, with one locking lug and one adjusting block corresponding to each other. The horizontal part of the locking lug has a through hole for communicating with the positioning hole. The positioning pin passes through the through hole and is inserted into the positioning hole. The locking hole is located on the vertical part of the locking lug.

[0010] Furthermore, the adjusting block and the locking lug plate are located on the upper and lower sides of the adjusting groove, and the fasteners lock the horizontal part of the adjusting block and the locking lug plate together. The bottom plate of the modeling vehicle is sandwiched between the horizontal part of the adjusting block and the locking lug plate.

[0011] Furthermore, a proximity switch is installed on the top surface of the conveyor vehicle. The proximity switch is configured to correspond to the pin of the spring pin, and the pin of the spring pin is used to trigger the proximity switch.

[0012] Furthermore, the transport support frame is equipped with sensors, and the base plate of the modeling vehicle is used to trigger the sensors.

[0013] Furthermore, the transmission drive mechanism includes a gearbox, a motor, and two flexible couplings. Both the gearbox and the motor are mounted on the bottom surface of the conveyor. The output shaft of the motor is driven to connect with the input shaft of the gearbox. The transmission rod includes two coaxial transmission shafts. The two flexible couplings are respectively fitted onto the two output shafts of the gearbox. One end of each of the two transmission shafts is inserted into the two flexible couplings, and two gears are respectively fitted onto the other ends of the two transmission shafts.

[0014] Furthermore, the transport vehicle is equipped with an oil injector, which is used to spray lubricating oil onto the slide rails and racks.

[0015] Furthermore, a limit switch is installed at both ends of the conveyor base, and the side of the conveyor is used to trigger the limit switch. The limit switch is electrically connected to the rotation drive mechanism.

[0016] The beneficial effects of this utility model are as follows: In practical applications, when the copying carrier is at the first station, a manual or loading robot places the hot-pressed workpiece on the copying carrier. The copying carrier supports and positions the hot-pressed workpiece. Then, the drive mechanism drives the transmission rod to rotate forward. The forward-rotating transmission rod drives two gears to rotate forward. The two forward-rotating gears mesh with two racks respectively, enabling the forward-rotating gears to drive the conveyor to move horizontally along the slide rails. This allows the conveyor, along with the copying carrier and the hot-pressed workpiece, to move from the first station to the second station. After the unloading robot unloads the hot-pressed workpiece at the second station, the drive mechanism drives the transmission rod to rotate in the opposite direction. The reverse-rotating transmission rod drives two gears to rotate in the opposite direction. The two reverse-rotating gears mesh with two racks respectively, enabling the conveyor to move in the opposite direction along the two slide rails. This allows the conveyor, along with the copying carrier, to move from the second station to the first station. Additionally, when it is necessary to support hot-pressed workpieces of different specifications or shapes, the drive spring pin retracts, causing it to move out of the lock hole to unlock the copying carrier. At this point, the copying carrier can be removed upwards from the transport vehicle. When a new copying carrier needs to be assembled on the transport vehicle, the spring pin is in the retracted state. After aligning each positioning hole on the bottom plate of the copying carrier with a positioning post, the bottom plate of the copying carrier is placed on the top surface of the transport vehicle, so that the positioning post is inserted into the positioning hole to position the copying carrier. This ensures the positional accuracy and stability of the copying carrier installed on the transport vehicle. Then, the drive spring pin extends, causing it to insert into the lock hole of the lock lug plate to securely lock the copying carrier on the transport vehicle. This invention enables the conveying of hot-pressed workpieces, and the assemblies and disassemblies of the copying carrier and the conveyor are convenient, making it easy to change the appropriate copying carrier according to different specifications or shapes of hot-pressed workpieces. The positional accuracy and stability of the assembly of the copying carrier and the conveyor are high. Attached Figure Description

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figures 1 to 5 As shown, the present invention provides an automatic hot-press unloading conveying device, which includes a base 1, two slide rails 2 parallel to both sides of the base 1, a conveying carriage 3 slidably connected to the two slide rails 2, two racks 4 mounted on both sides of the base 1 and parallel to the slide rails 2, two gears 5 rotatably connected to both ends of the conveying carriage 3, a transmission rod 6 drivingly connected to the two gears 5, a rotation drive mechanism 7 mounted on the bottom surface of the conveying carriage 3 for driving the transmission rod 6 to rotate, and a template detachably mounted on the top surface of the conveying carriage 3. The carrier 8 has two slide rails 2 that correspond one-to-one with two racks 4, and two gears 5 that mesh with the two racks 4 for transmission. The top surface of the conveyor 3 is provided with at least two positioning pins 9. The bottom plate of the modeling carrier 8 is provided with at least two positioning holes 10. One positioning pin 9 is engaged with one positioning hole 10. The top surface of the conveyor 3 is provided with at least one spring pin 11. The side of the bottom plate of the modeling carrier 8 is provided with at least one locking lug plate 12. The locking lug plate 12 has a locking hole 13. The pin shaft of the spring pin 11 can be inserted into the locking hole 13.

[0026] In practical applications, when the copying carrier 8 is at the first station, a manual or loading robot places the hot-pressed workpiece 29 on the copying carrier 8. The copying carrier 8 supports and positions the hot-pressed workpiece 29. Then, the drive mechanism 7 drives the transmission rod 6 to rotate forward. The forward-rotating transmission rod 6 drives two gears 5 to rotate forward. The two forward-rotating gears 5 mesh with two racks 4 respectively, so that the forward-rotating gears 5 can drive the conveyor 3 to move horizontally along the slide rail 2. This allows the conveyor 3, along with the copying carrier 8 and the hot-pressed workpiece 29, to move from the first station to the second station. After the unloading robot unloads the hot-pressed workpiece 29 at the second station, the drive mechanism 7 drives the transmission rod 6 to rotate in the opposite direction. The reverse-rotating transmission rod 6 drives two gears 5 to rotate in the opposite direction. The two reverse-rotating gears 5 mesh with two racks 4 respectively, so that the conveyor 3 moves in the opposite direction along the two slide rails 2. This allows the conveyor 3, along with the copying carrier 8, to move from the second station to the first station. In addition, when it is necessary to support hot-pressed workpieces 29 of different specifications or shapes, the pin shaft of the drive spring pin 11 is retracted, so that the pin shaft of the drive spring pin 11 is moved out of the lock hole 13 to unlock the copying carrier 8. At this time, the copying carrier 8 can be disassembled upwards from the conveyor 3. When it is necessary to assemble a new copying carrier 8 on the conveyor 3, the pin shaft of the drive spring pin 11 is in the retracted state. After aligning each positioning hole 10 of the bottom plate of the copying carrier 8 with a positioning post 9, the bottom plate of the copying carrier 8 is placed on the top surface of the conveyor 3, so that the positioning post 9 is inserted into the positioning hole 10 to position the copying carrier 8, thereby ensuring the positional accuracy and stability of the copying carrier 8 installed on the conveyor 3. Then, the pin shaft of the drive spring pin 11 is extended, so that the pin shaft of the drive spring pin 11 is inserted into the lock hole 13 of the lock lug plate 12 to securely lock the copying carrier 8 on the conveyor 3. This utility model can realize the conveying of hot-pressed workpiece 29, and the assembly and disassembly of the copying carrier 8 and the conveyor 3 are convenient, making it easy to replace the appropriate copying carrier 8 according to the hot-pressed workpiece 29 of different specifications or shapes. The positional accuracy and stability of the assembly of the copying carrier 8 and the conveyor 3 are high.

[0027] In this embodiment, at least two support frames 14 are installed on the top surface of the transport vehicle 3, and positioning posts 9 are disposed on the top surface of the support frames 14. The support frames 14 are used to support the bottom plate of the copying vehicle 8. After the copying vehicle 8 is assembled on the transport vehicle 3, the support frames 14 support the copying vehicle 8, thereby improving the stability of the copying vehicle 8 installed on the transport vehicle 3.

[0028] In this embodiment, the base plate of the copying vehicle 8 has at least two adjustment slots 15, and an adjustment block 16 is slidably connected in each adjustment slot 15. A positioning hole 10 is provided in one adjustment block 16, and the adjustment block 16 is located on the top surface of the base plate of the copying vehicle 8. The adjustment block 16 is locked to the base plate of the copying vehicle 8 by a fastener; specifically, the fastener can be a locking bolt. When it is necessary to adjust the relative position of the copying vehicle 8 on the conveyor 3, the fastener is loosened, so that the adjustment slots 15 on the base plate of the copying vehicle 8 can slide horizontally relative to the adjustment block 16, thereby adjusting the relative position of the copying vehicle 8 on the conveyor 3. After the position of the copying vehicle 8 is adjusted, the fastener is tightened, and the fastener locks the adjustment block 16 on the conveyor 3, thereby pressing and fixing the base plate of the copying vehicle 8 with the adjustment block 16.

[0029] In this embodiment, the number of locking lugs 12 is equal to the number of adjusting blocks 16, with one locking lug 12 corresponding to one adjusting block 16. The locking lug 12 is L-shaped, and the horizontal part of the locking lug 12 has a through hole 17 for communicating with the positioning hole 10. The positioning pin 9 passes through the through hole 17 and is inserted into the positioning hole 10. The locking hole 13 is provided in the vertical part of the locking lug 12. Specifically, the adjusting block 16 and the locking lug 12 are located on the upper and lower sides of the adjusting groove 15. The fastener locks the horizontal part of the adjusting block 16 and the locking lug 12 together. The bottom plate of the contour carrier 8 is sandwiched between the horizontal part of the adjusting block 16 and the locking lug 12. In practical applications, since the positioning pin 9 is inserted into the positioning hole 10 after passing through the through hole 17, the relative positions of the locking lug plate 12, the adjusting block 16, and the conveyor 3 are fixed. When it is necessary to adjust the relative position of the copying vehicle 8 on the conveyor 3, the fasteners are loosened so that the adjusting block 16 and the locking lug plate 12 loosen the bottom plate of the copying vehicle 8, thereby allowing the adjusting groove 15 on the bottom plate of the copying vehicle 8 to move relative to the adjusting block 16, thereby adjusting the relative position of the copying vehicle 8 and the conveyor 3. After the adjustment is completed, the fasteners are tightened so that the adjusting block 16 and the locking lug plate 12 clamp the bottom plate of the copying vehicle 8.

[0030] In this embodiment, a proximity switch 18 is installed on the top surface of the conveyor 3. The proximity switch 18 is correspondingly arranged with the pin of the spring pin 11, and the pin of the spring pin 11 is used to trigger the proximity switch 18. In practical applications, when the pin of the spring pin 11 is inserted into the lock hole 13, the pin of the spring pin 11 will trigger the proximity switch 18, proving that the pin of the spring pin 11 has been accurately inserted into the lock hole 13 of the lock lug plate 12. At this time, the present invention can start working.

[0031] In this embodiment, the support frame 14 is equipped with a sensor 19, and the base plate of the copying vehicle 8 is used to trigger the sensor 19. In practical applications, the base plate of the copying vehicle 8 triggers the sensor 19, and the pin shaft of the spring pin 11 triggers the proximity switch 18, proving that the copying vehicle 8 is accurately installed on the conveyor 3. At this time, the present invention can start working, ensuring the safety of use and the stability of operation.

[0032] In this embodiment, the rotation drive mechanism 7 includes a reduction gearbox 20, a motor 21, and two flexible couplings 22. Both the reduction gearbox 20 and the motor 21 are mounted on the bottom surface of the conveyor 3. The output shaft of the motor 21 is driven by the input shaft of the reduction gearbox 20. The transmission rod 6 includes two coaxially arranged transmission shafts 23. The two flexible couplings 22 are respectively fitted onto the two output shafts of the reduction gearbox 20. One end of each transmission shaft 23 is inserted into one of the two flexible couplings 22, and two gears 5 are respectively fitted onto the other ends of the two transmission shafts 23. In practical applications, the motor 21 drives the two flexible couplings 22 to rotate synchronously via the reduction gearbox 20. The two flexible couplings 22 drive the two transmission shafts 23 to rotate synchronously, and the transmission shafts 23 drive the gears 5 to rotate. The rotating gears 5 mesh with the fixed rack 4, allowing the conveyor 3 to slide along the slide rail 2.

[0033] In this embodiment, the conveyor 3 is equipped with an oil injector 24, which is used to spray lubricating oil onto the slide rail 2 and the rack 4. Specifically, the oil injector 24 can be an existing oil injection device, such as an automatic oil injection pump, which will not be described in detail here. In practical applications, the oil injector 24 periodically sprays lubricating oil onto the slide rail 2 and the rack 4 to lubricate them, reduce frictional resistance and wear, and make the conveyor 3 move smoothly.

[0034] In this embodiment, a limit switch 25 is installed at both ends of the base 1. The side of the conveyor 3 is used to trigger the limit switch 25, and the limit switch 25 is electrically connected to the rotation drive mechanism 7. The conveyor 3 moves back and forth between the two limit switches 25. When the conveyor 3 comes into contact with one of the limit switches 25, it means that the conveyor 3 has moved to the limit position. The rotation drive mechanism 7 stops driving the transmission rod 6 to rotate, so that the conveyor 3 stops moving.

[0035] Specifically, both ends of the base 1 are equipped with stops 26, which are used to abut the conveyor trolley 3. Preferably, the stops 26 are buffer blocks, such as silicone blocks. When the conveyor trolley 3 moves to its limit position, the stops 26 block the conveyor trolley 3, which on the one hand ensures the positional accuracy of the conveyor trolley 3 and on the other hand prevents the conveyor trolley 3 from disengaging from the slide rail 2 and the base 1. In addition, the stops 26 are buffer blocks, which play a role in buffering and noise reduction.

[0036] Specifically, the bottom surface of the base 1 is equipped with multiple support feet 27. The support feet 27 support the base 1, so that there is a certain space between the base 1 and the bottom surface, which facilitates cleaning of the bottom of the base 1.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
