Description

Technical Field

[0001] The present application relates to the field of thermoforming technology, and in particular to a positioning table for thermoforming technology and a thermoforming production line. Background Art

[0002] The hot forming (i.e. hot stamping) process is to heat the ultra-high strength sheet 10 in a heating furnace to the austenite temperature range. After the sheet 10 has completed the structural change, it is quickly moved to the mold for rapid stamping. Under the pressure holding state of the press, the parts are quenched and cooled through the cooling circuit arranged in the mold and a certain cooling speed is ensured, and finally the ultra-high strength stamping parts are obtained. Before sending the sheet 10 to the heating furnace, the sheet 10 needs to be positioned so that the material fork can accurately obtain the sheet 10, which is conducive to the material fork to accurately send the sheet 10 to the heating furnace.

[0003] The prior art uses a multi-degree-of-freedom manipulator (such as an articulated manipulator) to position the material sheet 10. Specifically, the manipulator drives the material sheet 10 to perform multi-degree-of-freedom movements to adjust the position and posture of the material sheet 10, thereby accurately delivering the material sheet 10 to the desired position on the material fork in the desired posture.

[0004] In order to achieve the positioning of the material sheet 10 (ie, to achieve the required posture and position of the material sheet 10), the prior art uses a multi-degree-of-freedom manipulator to perform multiple degrees of freedom movements, which makes motion control difficult and thus seriously affects the working efficiency of the thermoforming process. Utility Model Content

[0005] In order to more conveniently position the material sheet and improve the efficiency of the thermoforming process, the present application provides a positioning table for a thermoforming process and a thermoforming production line.

[0006] The present application provides a positioning table for a thermoforming process and a thermoforming production line that adopts the following technical solutions:

[0007] A positioning table for a thermoforming process includes a support table and a positioning seat slidably connected to the support table, a positioning device is provided on the positioning seat, and the positioning device includes a positioning plate, a clamping member and a driving member. The driving member is used to drive the positioning seat to rotate and then drive a material plate to abut against the positioning plate, and the clamping member is used to clamp and fix the material plate on the positioning seat.

[0008] By adopting the above technical solution, the sliding setting of the support table and the positioning seat can change the position of the material plate placed on the positioning device; the coordinated setting of the driving member and the positioning plate can drive the positioning seat to rotate, and then drive the material plate on the positioning seat to move to abut against the positioning plate, thereby realizing the adjustment of the position of the material plate; the setting of the clamping member can fix the position of the material plate on the positioning seat after the position of the material plate is adjusted.

[0009] Optionally, the driving member 1 includes a rack arranged on the support platform, a gear rotatably connected to the support platform, and a driving member 2 for driving the rack to reciprocate horizontally, the gear is meshed with the rack, and the positioning seat is connected to the gear.

[0010] By adopting the above technical solution, the second driving member drives the rack to perform reciprocating sliding translational motion, thereby driving the gear meshing with the rack to reciprocate and rotate a certain angle to achieve the adjustment of the horizontal and tilted state of the positioning seat, so that the positioning plate can be tilted to the lowest end of the positioning seat, thereby achieving the abutment between the material plate and the positioning plate.

[0011] Optionally, the clamping member includes a clamping block slidably connected to the positioning seat and horizontally opposite to the positioning seat, and the clamping block is used to clamp the material plate and fix it on the positioning seat.

[0012] By adopting the above technical solution, the horizontally opposite clamping blocks can clamp and fix the material sheet on the positioning seat after the positioning plate and the driving member adjust the position of the material sheet on the positioning seat.

[0013] Optionally, a fixing block is fixedly connected to the positioning seat, a spring is connected between the fixing block and the clamping block, and the spring is used to push the clamping block to squeeze the material plate.

[0014] By adopting the above technical solution, the spring applies a thrust to the clamping block, so that the clamping block moves toward the direction approaching the material sheet to squeeze the material sheet.

[0015] Optionally, an electromagnet device is provided between the fixing block and the clamping block.

[0016] By adopting the above technical solution, the arrangement of the electromagnet device can pull the clamping block away from the material plate when the material plate is loaded or unloaded, thereby leaving enough room for the material plate to move.

[0017] Optionally, a push block is slidably connected to the positioning seat, and the push block is used to push the material plate to abut against the positioning plate.

[0018] By adopting the above technical solution, the material plate moves downward under the action of gravity, and may collide with the positioning plate and rebound. The setting of the push block can push the material plate again to abut against the positioning plate.

[0019] Optionally, a driving component three for driving the push block to perform horizontal and vertical movements is installed on the support platform, a sliding hole is opened on the positioning seat, the push block extends through the sliding hole to a side of the positioning seat away from the support platform, and the push block slides horizontally along the sliding hole.

[0020] By adopting the above technical solution, the driving component three drives the push block to be located on the side of the positioning seat facing the support platform under normal circumstances. When the material plate collides with the positioning plate and rebounds, the driving component three will drive the material plate to extend out of the sliding hole and push the material plate along the direction of the sliding hole to re-connect with the positioning plate.

[0021] Optionally, an infrared radiation device is installed on the positioning seat, and the infrared radiation device is used to cooperate with the pushing block to adjust the position of the material plate.

[0022] By adopting the above technical solution and setting the infrared emitting device, the position of the material plate can be detected, and then the position of the material plate can be adjusted in cooperation with the push block.

[0023] Optionally, a V-shaped groove is formed on one side of the clamping blocks that are close to each other, and the material sheet is partially embedded in the V-shaped groove.

[0024] By adopting the above technical solution, the setting of the V-shaped groove can enable the material plate to enter the V-shaped groove along the curvature of the V-shaped groove and be clamped, thereby reducing the probability of the material plate moving or falling off the positioning plate during the angle adjustment process.

[0025] A thermoforming production line includes the above-mentioned positioning table for thermoforming process, and also includes a feeding device and a material picking device arranged on opposite sides of the support table. The material picking device includes a plurality of insertion rods, and the plurality of the insertion rods are arranged side by side and at intervals. The plurality of the insertion rods are used to be inserted into the gap between the positioning seat and the material sheet to unload the material sheet.

[0026] By adopting the above technical solution, when in use, the feeding device feeds the material plate to the positioning seat, and after adjustment by the positioning device, the insertion rod extends into the gap between the positioning seat and the material plate to support the material plate and unload the material plate.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the coordination of the positioning plate and the driving member 1, the driving member 1 makes the positioning seat in a horizontal or inclined state through the meshing movement of the rack and the gear. When the positioning seat is in an inclined state, the material plate on the positioning seat can move along the slope of the positioning seat under the action of gravity to abut against the positioning plate, thereby realizing the adjustment of its own position;

[0029] 2. Through the coordinated arrangement of the clamping block, the fixing block, the spring and the electromagnet device, the spring can drive the clamping block to squeeze and position the material plate on the positioning seat, and the electromagnet device can drive the clamping block to leave the material plate and leave space for loading and unloading of the material plate.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The present application discloses a positioning table for a thermoforming process and a thermoforming production line. Figure 1 A positioning table for a thermoforming process includes a support frame 1, a support table 11 installed on the support frame 1, a positioning seat 2 slidably connected to the support table 11, and a sliding device 3 for driving the positioning seat 2 to slide. The positioning seat 2 is also provided with a positioning device 4 for adjusting and fixing the position of a material sheet 10.

[0038] Reference Figure 1 and Figure 2The positioning device 4 includes a positioning plate 41 horizontally fixed on the positioning seat 2 and a driving member 42 for driving the positioning seat 2 to rotate. The positioning plate 41 is located at a side edge close to the positioning seat 2, and the driving member 42 is arranged between the positioning seat 2 and the sliding device 3. When in use, after the material plate 10 is placed on the positioning seat 2 by the manipulator 81, the driving member 42 can drive the positioning seat 2 to rotate, and drive the positioning seat 2 to rotate until the positioning plate 41 is located close to the lowest end of the slope of the positioning seat 2. At this time, the material plate 10 moves toward the direction of the positioning plate 41 under the action of gravity and abuts against the positioning plate 41, thereby adjusting the material plate 10 to a state flush with the positioning plate 41, and then the driving member 42 drives the positioning seat 2 to rotate and restore to a horizontal state.

[0039] Reference Figure 2 and Figure 3 , a horizontal plate 12 is horizontally arranged between the positioning seat 2 and the driving device. The driving member 42 includes a first cylinder 421 installed on the horizontal plate 12, a rack 422 horizontally fixed to the piston rod of the first cylinder 421, and a gear 423 rotatably connected to the horizontal plate 12. A support rod 121 is vertically fixed to the middle part of the horizontal plate 12, and the gear 423 is rotatably connected to the support rod 121. The side of the gear 423 facing the horizontal plate 12 is meshed with the rack 422, and the side of the gear 423 away from the horizontal plate 12 is fixed to the bottom of the positioning seat 2. When in use, the movement direction of the piston rod of the first cylinder 421 is flush with the horizontal plate 12, and the piston rod of the first cylinder 421 drives the rack 422 to drive the gear 423 to rotate by extending and shortening, thereby driving the positioning seat 2 to rotate a set angle or restore the horizontal state.

[0040] Reference Figure 1 The positioning device 4 further includes a clamping member 43 disposed on the positioning seat 2. The clamping member 43 can clamp the two sides of the material sheet 10 adjacent to the side abutting the positioning plate 41 when the material sheet 10 moves to abut against the positioning plate 41, thereby fixing the position of the material sheet 10 on the positioning plate 41.

[0041] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The clamping member 43 includes two clamping blocks 431 which are slidably connected to the positioning seat 2 and are horizontally opposite to each other, and a clamping space 5 for fixing the material plate 10 is formed between the two clamping blocks 431. The bottoms of the two clamping blocks 431 are respectively fixed with first sliders 432, and the positioning seat 2 is provided with first slide grooves 21 for the two first sliders 432 to be inserted and slide. Two horizontally opposite fixing blocks 433 are fixed to the positioning seat 2 and located near the two side edges of the positioning seat 2. The two fixing blocks 433 are respectively located on the side of the two clamping blocks 431 away from each other. A spring 434 is connected between the adjacent fixing blocks 433 and the clamping blocks 431, and a pair of electromagnet devices 6 are installed.

[0042] During use, when the material sheet 10 moves to abut against the positioning plate 41, the electromagnet device 6 is not energized, and the spring 434 pushes the clamping block 431 to move toward the material sheet 10, squeezing and fixing the material sheet 10; when the material sheet 10 is loaded and unloaded, the electromagnet device 6 is energized, and the clamping block 431 retreats toward the direction of the fixing block 433 under the action of the electromagnet device 6, thereby leaving sufficient space for the material sheet 10 to load and unload.

[0043] Reference Figure 3 and Figure 4 Since the sheet 10 may be rebounded a certain distance to affect the positioning of the sheet 10 during the collision with the positioning plate 41, a push piece 44 is provided to push the sheet 10 back to abut against the positioning plate 41, and an infrared emitting device 7 is provided to cooperate with the push piece 44. The transmitting end and the receiving end of the infrared emitting device 7 are respectively installed at the opposite ends of the two clamping blocks 431.

[0044] The push piece 44 includes a linear motor 441 installed on the horizontal plate 12, a second cylinder 442 installed on the slider of the linear motor 441, and a push block 443 fixedly connected to the piston rod of the second cylinder 442. A sliding hole 22 is provided on the positioning seat 2 for the push block 443 to pass through and slide toward the positioning plate 41.

[0045] It can be understood that a PLC controller for controlling the first cylinder 421, the second cylinder 442, the linear motor 441, the electromagnet device 6 and the infrared emitting device 7 is provided on the support table 11. When in use, the PLC controller starts the first cylinder 421 and the infrared emitting device 7, energizes the electromagnet device 6, and the piston rod of the first cylinder 421 extends to drive the rack 422 and the gear 423 to rotate, thereby driving the positioning seat 2 to tilt, and at this time the material plate 10 on the positioning seat 2 will move toward the direction of the positioning plate 41. When the material plate 10 abuts against the positioning plate 41, the receiving end of the infrared emitting device 7 will receive the signal from the transmitting end, and at this time the PLC controller will receive the signal transmitted by the infrared emitting device 7 and stop energizing the electromagnet, and the two clamping blocks 431 clamp the two sides of the material plate 10 under the thrust of the spring 434 to fix it. In this process, when the receiving end of the infrared emitting device 7 cannot receive the signal from the transmitting end, the PLC controller controls the second cylinder 442 and the linear motor 441 to work, so that the push block 443 extends through the slide hole 22 to the top of the positioning seat 2 to push the material plate 10 until the material plate 10 abuts against the positioning plate 41. When the piston rod of the first cylinder 421 is extended to the limit and the receiving end of the infrared emitting device 7 can continue to receive the signal from the transmitting end, the PLC controller controls the first cylinder 421 to move again to drive the positioning seat 2 to rotate to restore the horizontal state.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The sliding device 3 includes a second slider 31 fixed to the bottom of the horizontal plate 12 and a horizontal slide rail 32 slidably connected to the support platform 11. The length direction of the horizontal slide rail 32 is parallel to the length direction of the support platform 11, and a second slide groove 321 is provided on the horizontal slide rail 32 for the second slider 31 to be inserted and slide along the length direction of the horizontal slide rail 32. When in use, the position of the positioning seat 2 on the support platform 11 can be adjusted by pushing the horizontal plate 12 to move along the length direction of the horizontal slide rail 32.

[0047] Reference Figure 5 The sliding device 3 further includes a third sliding block 33 fixed to the bottom of the horizontal sliding rail 32, and a third sliding groove 111 is provided on the support platform 11 for the third sliding block 33 to be inserted into and slide along the width direction of the support platform 11. When in use, the position of the positioning seat 2 on the support platform 11 can be adjusted by pushing the horizontal sliding rail 32 to move along the width direction of the support platform 11.

[0048] It is understandable that the shapes of the first slider 432, the second slider 31 and the third slider 33 can be T-shaped, dovetail-shaped, etc. The embodiment of the present application takes the shape of the first slider 432, the second slider 31 and the third slider 33 as T-shaped as an example for explanation.

[0049] The embodiment of the present application also proposes a thermoforming production line, which includes a positioning table for the thermoforming process as above. The specific structure of the positioning table for the thermoforming process refers to the above embodiment. Since the thermoforming production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0050] Reference Figure 1 In the embodiment of the present application, the thermoforming production line further includes a feeding device 8 and a taking device 9, which are respectively located on opposite sides of the support frame 1. The feeding device 8 includes a manipulator 81 for grabbing the material plate 10 and a control mechanism for controlling the manipulator 81.

[0051] Reference Figure 1 and Figure 5 The material taking device 9 includes a plurality of inserted rods 91 arranged side by side and at intervals and a driving mechanism for driving the inserted rods 91 to move. In order to cooperate with the movement of the inserted rods 91, the two clamping blocks 431 are respectively provided with V-shaped grooves 4311 on the sides close to each other for the ends of the feed plate 10 to be embedded. When in use, the material plate 10 can enter the V-shaped groove 4311 along the slope of the V-shaped groove 4311 and be lifted up, so that a certain gap is pulled between the material plate 10 and the positioning seat 2, and the inserted rods 91 penetrate the gap between the feed plate 10 and the positioning seat 2 and support the material plate 10, so as to complete the unloading of the material plate 10.

[0052] It can be understood that the structure and function of the feeding device 8 and the material taking device 9 in the embodiment of the present application are consistent with the structure and function of the feeding device 8 and the material taking device 9 on the existing thermoforming production line, and will not be described in detail here.

[0053] The implementation principle of a positioning table and a hot forming production line for a hot forming process in the embodiment of the present application is as follows: in the initial state, the PLC controller controls the electromagnet device 6 to be energized, the two clamping blocks 431 are adsorbed around the fixed block 433, and the piston rod of the first cylinder 421 is extended to drive the positioning seat 2 to maintain a horizontal state. The control mechanism is started to operate the manipulator 81 to send the material plate 10 to the positioning seat 2, and then the PLC controller controls the first cylinder 421 to work, and the piston rod of the first cylinder 421 is shortened to drive the rack 422 to drive the positioning seat 2 to rotate. During the rotation of the positioning seat 2, the material plate 10 on the positioning seat 2 will slide down along the slope of the positioning seat 2 under the action of its own gravity until the material plate 10 abuts against the positioning seat 2, and the position of the material plate 10 is adjusted to be flush with the positioning plate 41. Then the PLC controller controls the electromagnet device 6 to stop energizing, and the clamping blocks 431 on both sides move toward the material plate 10 under the action of the springs 434. The two ends of the material plate 10 enter the two V-shaped grooves 4311 and are clamped. The first cylinder 421 continues to be controlled to work, and the piston rod of the first cylinder 421 extends to drive the positioning seat 2 to rotate and restore to a horizontal state.

[0054] After the positioning seat 2 is restored to a horizontal state, the material sheet 10 on the positioning plate 41 is also adjusted. At this time, the driving mechanism drives the insertion rod 91 to enter the gap between the positioning seat 2 and the material sheet 10 and hold the material sheet 10. The PLC controller controls the electromagnet device 6 to be energized again. Under the action of the electromagnet device 6, the two clamping blocks 431 move in a direction away from the material sheet 10, and the driving device drives the insertion rod 91 to move the material sheet 10 away.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
