Description

Technical Field

[0001] This utility model relates to the field of hot pressing and film application technology for sheet metal, and more specifically, to a sheet metal transport device for a hot press machine. Background Technology

[0002] The hot-press lamination process for boards involves using a hot press to heat and pressurize the surface film to bond it tightly to the board.

[0003] In the existing technology, when processing sheet metal by hot pressing and laminating, the sheet metal needs to be manually controlled to fall at a designated position on the hot pressing conveyor belt. A surface film is placed at this designated position in advance. This surface film is laid on the bottom side of the sheet metal. Then, another surface film is laid on the top side of the sheet metal by manual operation. As the hot pressing conveyor belt moves, the sheet metal and the surface films on both sides are fed into the hot press machine for hot pressing and laminating.

[0004] It should be noted that during the above processing, the board may shift significantly in position during manual positioning, resulting in the lack of surface film on the bottom part of the board. This affects the subsequent hot pressing process, impacts the quality of the finished product, and may even lead to material waste. Even if the board is manually adjusted to align with the surface film, the following problems remain: manual operation is inefficient (average time 35 minutes / piece), and positioning errors exceeding ±5mm can easily lead to hot pressing failure (with a scrap rate as high as 8%-12%).

[0005] Therefore, how to achieve precise positioning and placement of the board material and accurate application of the surface film is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a sheet material transport device for a hot press. This device can achieve precise positioning and placement of the sheet material, and at the same time, it uses a laser line to guide the laying of the surface film, so that there is no need to manually adjust the position of the sheet material, saving time and effort.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sheet metal conveying device for a hot press includes:

[0009] The frame has a horizontally extending synchronous belt at the bottom of its top, which is used to move the sheet material horizontally into the hot press.

[0010] A telescopic mechanism is provided at the top of the frame and can be extended vertically.

[0011] A drive mechanism, connected to the telescopic mechanism, is used to drive the telescopic mechanism to move laterally on the frame;

[0012] A gripping mechanism, located on the telescopic mechanism, is used to grip the sheet material onto the synchronous belt;

[0013] A laser receiver is located beside the synchronization belt;

[0014] A laser generator is located at the top of the frame and is positioned opposite to the laser receiver. The laser beam emitted by the laser generator is perpendicular to the direction of movement of the synchronization belt and is received by the laser receiver.

[0015] The control unit is signal-connected to the laser receiver, the telescopic mechanism, and the drive mechanism.

[0016] Preferably, the telescopic mechanism includes a first support plate, a second support plate, and a vertical driver connected to the control unit. The first support plate is movably disposed at the top of the frame in a lateral direction. The vertical driver is disposed at the bottom end face of the first support plate and its telescopic rod is connected downward to the second support plate. The gripping mechanism is disposed on the second support plate.

[0017] Preferably, there are multiple vertical actuators, and at least four of the vertical actuators are located between the four corners of the first support plate and the second support plate.

[0018] Preferably, the gripping mechanism includes multiple suction cups, and at least four of the suction cups are located at the four corners of the bottom end face of the second support plate.

[0019] Preferably, the top of the frame has an opening, and the first support plate is movably disposed in the opening in a laterally direction.

[0020] Preferably, the driving mechanism includes a slider, a slide rail, and a transverse driver connected to the control unit. The top of the frame is provided with slide rails extending transversely on both sides of the opening along the longitudinal direction. Each slide rail is slidably provided with a slider connected to the first support plate, and each slider is connected to the transverse driver located at the end of the slide rail.

[0021] Preferably, it further includes a feeding rack for stacking a plurality of the plates, the feeding rack being located on the side of the end of the synchronous belt that is laterally away from the hot press, and the gripping mechanism is initially located above the feeding rack.

[0022] Preferably, the frame body has a notch on one side of the perimeter adjacent to the loading rack for the loading rack to pass through, and the bottom end of the loading rack is provided with casters.

[0023] Preferably, it further includes a synchronous belt conveyor mechanism, which includes a frame, a synchronous belt, and a synchronous belt drive mechanism. The frame is disposed below the top of the frame and extends laterally. The synchronous belt is wound around the frame and connected to the synchronous belt drive mechanism. The synchronous belt drive mechanism is used to drive the synchronous belt to rotate on the frame.

[0024] Preferably, the frame has a first slot extending laterally on the side adjacent to its synchronous belt, and the laser receiver has a first locking block that engages with and slides in the first slot.

[0025] The top of the frame is provided with a second slot on the side facing the machine frame, which is opposite to the first slot and extends laterally. The laser generator is provided with a second card block, which is inserted into the second slot and slides in cooperation with it.

[0026] The sheet metal conveying device for the hot press provided by this utility model operates by emitting a laser beam perpendicular to the direction of movement of the synchronous belt. The laser beam indicates the boundary for surface film laying. The operator can manually lay the first surface film at the designated position on the synchronous belt using the laser beam. Simultaneously, the telescopic mechanism extends downwards, causing the gripping mechanism to move downwards and grasp the sheet metal. Then, the telescopic mechanism retracts upwards, causing the gripping mechanism to move upwards and lift the sheet metal. The drive mechanism then moves the telescopic mechanism and its gripping mechanism laterally. When the sheet metal is transported above the designated position on the synchronous belt, it blocks the laser generator. The laser receiver, unable to receive the laser, sends an electrical signal to the control unit. The control unit sends a control signal to the telescopic mechanism according to preset control logic. The telescopic mechanism extends downwards, causing the gripping mechanism to place the sheet metal at the designated position on the synchronous belt, aligning the bottom of the sheet metal with the first surface film. The telescopic mechanism and drive mechanism then reset the gripping mechanism to prepare for grasping the next sheet metal. Simultaneously, the operator lays the second surface film on the top side of the sheet metal. Finally, the operator starts the synchronous belt, feeding the sheet metal and the surface films on both sides of the sheet metal into the hot press for hot pressing and lamination.

[0027] In summary, this application guides the manual laying of the surface film with a laser beam, ensuring that the surface film is laid at a designated position on the synchronous belt. Furthermore, by using the plate to block the laser beam, the gripping mechanism is triggered to stop its lateral movement, thereby achieving plate position calibration and ensuring that the plate stops at a designated position on the synchronous belt. This ensures that the bottom side of the plate is aligned with the surface film, thus eliminating the need for manual adjustment of the plate position and saving time and effort.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] The core of this utility model is to provide a sheet material transport device for a hot press. This device can achieve precise positioning and placement of the sheet material, and at the same time, it uses a laser line to guide the laying of the surface film, so that there is no need to manually adjust the position of the sheet material, saving time and effort.

[0037] It should be noted that in this embodiment, the orientation or positional relationship indicated by "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of facilitating the description of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0038] Please refer to Figure 1 and Figure 2This application provides a specific embodiment of a sheet metal transport device for a hot press, including a frame 1, a telescopic mechanism 3, a drive mechanism 4, a gripping mechanism 5, a laser receiver 6, a laser generator 7, and a control unit.

[0039] A synchronous belt 2 extending laterally is provided below the top of the frame 1 to drive the sheet material to move laterally into the hot press. A telescopic mechanism 3 is located at the top of the frame 1 and is vertically extendable. A drive mechanism 4 is connected to the telescopic mechanism 3 and drives the telescopic mechanism 3 to move laterally on the frame 1. A gripping mechanism 5 is located on the telescopic mechanism 3 and grips the sheet material onto the synchronous belt 2. A laser receiver 6 is located beside the synchronous belt 2. A laser generator 7 is located at the top of the frame 1 and is positioned opposite the laser receiver 6. The laser beam emitted by the laser generator 7 is perpendicular to the direction of movement of the synchronous belt 2 and is received by the laser receiver 6. A control unit is connected to the laser receiver 6, the telescopic mechanism 3, and the drive mechanism 4.

[0040] It should be noted that there is a space below the top of the frame 1, and the telescopic mechanism 3 and its connected gripping mechanism 5 and synchronous belt 2 are all located in the space.

[0041] Synchronous belt 2 has the function of conveying materials. Synchronous belt 2 extends laterally and can be connected to a synchronous belt drive mechanism. The synchronous belt drive mechanism can drive synchronous belt 2 to rotate, thereby moving the sheet material laterally into the hot press. It should be noted that the end of synchronous belt 2 furthest from the hot press in the lateral direction is the feeding end. A sheet material placement area can be set up next to the feeding end for stacking multiple sheets to be hot-pressed.

[0042] The telescopic mechanism 3 is a mechanical structure that can change its length vertically. It is located at the top of the frame 1 and can move vertically (i.e., up and down) by extending and retracting. Additionally, the telescopic mechanism 3 is movably mounted at the top of the frame 1 and is connected to a drive mechanism 4. The drive mechanism 4 serves as the power source for the telescopic mechanism 3, enabling it to move laterally. Thus, the telescopic mechanism 3 can move both laterally and vertically below the top of the frame 1 (i.e., within the receiving space).

[0043] The gripping mechanism 5 is capable of gripping the sheet material. The gripping mechanism 5 is mounted on the telescopic mechanism 3, allowing the telescopic mechanism 3 to move the gripping mechanism 5 horizontally and vertically within the accommodating space. It should be noted that the telescopic mechanism 3 and its gripping mechanism 5 are initially positioned above the sheet material placement area.

[0044] The laser receiver 6 is located on the side of the synchronous belt 2. It should be noted that there is a preset distance between the laser receiver 6 and the feeding end of the synchronous belt 2. This preset distance can be determined according to the length of the board. Moreover, the horizontal position of the synchronous belt 2 where the laser receiver 6 is located serves as the boundary for the placement of the board and the laying of the surface film (that is, the designated position of the synchronous belt 2).

[0045] The laser generator 7 is located at the top of the frame 1, above the synchronous belt 2. The emission port of the laser generator 7 is perpendicular to the movement direction of the synchronous belt 2 (i.e., horizontal), so that the laser beam emitted by the laser generator 7 is perpendicular to the movement direction of the synchronous belt 2. Moreover, the laser generator 7 is positioned opposite to the laser receiver 6. Thus, the laser beam can mark the placement position of the board and guide the manual laying of the surface film, and the laser beam is received by the laser receiver 6.

[0046] The control unit can receive the signal output by the laser generator 7, and then control the telescopic mechanism 3 and the drive mechanism 4 to move according to the preset control logic, so that the gripping mechanism 5 grips the board from the initial position and transports the board to the designated position of the synchronous belt 2, thereby realizing the automated transport of the board.

[0047] In the above embodiment, the sheet metal conveying device for the hot press is used such that the laser beam emitted by the laser generator 7 is perpendicular to the movement direction of the synchronous belt 2. The laser beam can indicate the surface film laying boundary. The first surface film can be laid at the designated position on the synchronous belt 2 by manually relying on the laser beam. At the same time, the telescopic mechanism 3 is controlled to extend downward, driving the gripping mechanism 5 to move downward to grip the sheet metal. Then, the telescopic mechanism 3 is controlled to retract upward, driving the gripping mechanism 5 to move upward to lift the sheet metal. Then, the drive mechanism 4 is controlled to drive the telescopic mechanism 3 and the gripping mechanism 5 to move laterally together. When the sheet metal is transported above the designated position on the synchronous belt 2, The board will block the laser generator 7, and the laser receiver 6 will not be able to receive the laser and will send an electrical signal to the control unit. The control unit can send a control signal to the telescopic mechanism 3 according to the preset control logic. The telescopic mechanism 3 extends downward to drive the gripping mechanism 5 to place the board at the designated position of the synchronous belt 2 so that the bottom side of the board is aligned with the first surface film. Then, the telescopic mechanism 3 and the drive mechanism 4 are controlled to reset the gripping mechanism 5 to prepare to grip the next board. At the same time, the second surface film is laid on the top side of the board by manual operation. Finally, the synchronous belt 2 is manually started to send the board and the surface films on both sides of the board into the hot press for hot pressing and film application.

[0048] Therefore, this application can use the laser beam emitted by the laser sensor to calibrate the placement position of the board and guide the manual laying of the surface film, which can ensure that the board and the surface film are aligned and avoid large offset of the board relative to the surface film. This eliminates the need for manual adjustment of the board position, thereby reducing the intensity of manual labor and shortening the production time.

[0049] Based on the above embodiments, and considering the specific arrangement of the telescopic mechanism 3, as a preferred option, please refer to... Figure 1 and Figure 2 The telescopic mechanism 3 includes a first support plate 31, a second support plate 32, and a vertical driver 33 connected to the control unit. The first support plate 31 is movably disposed at the top of the frame 1 in the lateral direction. The vertical driver 33 is disposed at the bottom end of the first support plate 31 and its telescopic rod is connected downward to the second support plate 32. A gripping mechanism 5 is disposed on the second support plate 32.

[0050] One end of the vertical actuator 33 is fixed to the top of the frame 1 via the first support plate 31, and the other end of the vertical actuator 33 is connected to the gripping mechanism 5 via the second support plate 32. When the telescopic rod of the vertical actuator 33 moves downward, it can drive the gripping mechanism 5 to move downward, thereby realizing the gripping of the board or driving the board to move downward. When the telescopic rod of the vertical actuator 33 moves upward, it can drive the gripping mechanism 5 to move upward, thereby realizing the upward extraction of the board.

[0051] Based on the above embodiments, as a further preferred embodiment, multiple vertical actuators 33 are provided, with at least four vertical actuators 33 located between the four corners of the first support plate 31 and the second support plate 32. The multiple vertical actuators 33 work together to efficiently drive the gripping mechanism 5 up and down, thereby improving the transport efficiency of the sheet metal. Furthermore, they can smoothly drive the gripping mechanism 5 up and down, reducing the risk of the gripping mechanism 5 shifting or even falling off during transport, thus improving the reliability of sheet metal transport.

[0052] Based on the above embodiments, and considering the specific configuration of the gripping mechanism 5, as a preferred option, please refer to... Figure 2 The gripping mechanism 5 includes multiple suction cups, with at least four suction cups located at the four corners of the bottom surface of the second support plate 32.

[0053] The suction cups can utilize the pressure difference between the inside and outside atmospheres or magnetic force to adhere the sheet material, thereby achieving the gripping of the sheet material. At least four suction cups are positioned at the four corners of the bottom surface of the second support plate 32, which can firmly adhere the sheet material, reducing the risk of displacement or even detachment during transportation, thus further improving the reliability of sheet material transportation. The specific structure of the suction cups can be found in existing technology, but it is not the focus of this application and will not be described in detail here.

[0054] Of course, the gripping mechanism 5 can also be a gripper. The gripper is connected to the control unit by a signal and can be controlled to open and close automatically, thereby realizing the gripping and placement of the board.

[0055] Based on the above embodiments, and considering the specific arrangement of the frame 1, as a preferred embodiment, the frame 1 can be used as a workbench for placing boards and laying surface films. The top of the frame 1 has an opening, and the first support plate 31 is movably disposed in the opening along the lateral direction.

[0056] Before transporting the sheet material, a worker can manually lay the first surface film at the designated position on the synchronous belt 2 through the opening. After the sheet material is placed, the telescopic mechanism 3 and its connected gripping mechanism 5 will reset. At this time, there is no obstruction above the sheet material, and a worker can then lay the second surface film on the top layer of the sheet material through the opening. Therefore, an opening is provided at the top of the frame 1 to facilitate manual laying of the surface film.

[0057] It should be noted that the first support plate 31 is movably disposed in the opening along the lateral direction, and the lateral dimension of the first support plate 31 is smaller than the lateral dimension of the opening. The first support plate 31 is initially located directly above the plate placement area. When transporting the plate, the drive mechanism 4 is connected to the first support plate 31 to drive the first support plate 31 to move laterally, thereby moving the plate to the designated position of the synchronous belt 2.

[0058] Based on the above embodiments, and considering the specific arrangement of the drive mechanism 4, as a preferred option, please refer to... Figure 1 The drive mechanism 4 includes a slider 41, a slide rail 42, and a transverse driver 43 connected to the control unit. Slide rails 42 extending transversely are provided on both sides of the opening at the top of the frame 1. A slider 41 connected to the first support plate 31 slides on each slide rail 42, and each slider 41 is connected to a transverse driver 43 located at the end of the slide rail 42. Thus, activating the transverse driver 43 moves the slide rail 42, causing the first support plate 31 to move transversely within the opening of the frame 1. The sliding cooperation between the slide rail 42 and the slider 41 ensures stable transverse movement of the first support plate 31, thereby accurately and smoothly transporting the plate to the designated position above the synchronous belt 2, achieving precise positioning of the plate.

[0059] Based on the above embodiments, and considering the specific arrangement of the synchronous belt 2, as a preferred embodiment, this application also includes a synchronous belt conveying mechanism. The synchronous belt conveying mechanism includes a frame, a synchronous belt 2, and a synchronous belt drive mechanism. The frame is located below the top of the frame 1 and extends laterally. The synchronous belt 2 is wound around the frame and connected to the synchronous belt drive mechanism. The synchronous belt drive mechanism is used to drive the synchronous belt 2 to rotate on the frame.

[0060] Using a synchronous belt conveyor to feed the sheet material into the hot press ensures uniform and stable speed during the conveying process, thereby improving production efficiency. Furthermore, the synchronous belt drive mechanism can be connected to a control unit. After the second layer of surface film is manually laid, the control unit (e.g., a computer system) can be operated to activate the synchronous belt drive mechanism, driving the synchronous belt 2 to rotate and thus feeding the sheet material into the hot press.

[0061] Regarding the specific configuration of the synchronous belt drive mechanism, as a preferred embodiment, the synchronous belt drive mechanism includes a driving wheel, a driven wheel, and a driving wheel driver. The driving wheel and the driven wheel are rotatably located at both ends of the frame laterally. The driving wheel driver is located on the frame and connected to the driving wheel. The synchronous belt 2 connects the driving wheel and the driven wheel.

[0062] To achieve laser beam position adjustment, based on the above embodiments, as a preferred embodiment, the frame has a first slot extending laterally on the side adjacent to its synchronization belt 2, the laser receiver 6 has a first locking block, the first locking block is inserted into the first slot and slides with it; the top of the frame 1 facing the frame has a second slot that is opposite to the first slot and extends laterally, the laser generator 7 has a second locking block, the second locking block is inserted into the second slot and slides with it.

[0063] It should be noted that the divergence angle of the laser beam is very small. The laser generator 7 and the laser receiver 6 need to be set relative to each other for the laser receiver 6 to receive the laser beam emitted by the laser generator 7. Otherwise, the laser beam may deviate from the receiving range of the laser receiver 6, causing the laser receiver 6 to be unable to receive the laser signal.

[0064] If the size and specifications of the sheet material change, the designated position of the timing belt 2 needs to be adjusted. Generally, if the lateral dimension (i.e., length) of the sheet material increases, the designated position of the timing belt 2 needs to be moved a suitable distance toward the hot press. Conversely, if the lateral dimension (i.e., length) of the sheet material increases, the designated position of the timing belt 2 needs to be moved a certain distance toward its feeding end.

[0065] Taking the increase in the lateral dimension (i.e., length) of the board as an example, the first card block is moved a suitable distance along the first card slot toward the hot press, so that the laser receiver 6 is moved to the boundary position of the board and the surface film to receive the laser beam. At this time, the designated position of the synchronous belt 2 changes, and the position of the laser beam also needs to be adjusted accordingly. That is, the second card block is moved a suitable distance along the second card slot toward the hot press, and the calibrated position of the laser beam on the synchronous belt 2 is adjusted to the new designated position of the synchronous belt 2.

[0066] Therefore, by adopting the above structure, the position of the laser beam can be adjusted to adapt to the different sizes and specifications of the sheet material.

[0067] To facilitate the gripping mechanism 5 in gripping the material plates, as a further preferred embodiment, this application also includes a feeding rack for stacking several plates. The feeding rack is located on the side of the synchronous belt 2, which is furthest from the hot press in the lateral direction. The gripping mechanism 5 is initially positioned above the feeding rack. In other words, by setting up the feeding rack in the plate placement area, it is convenient to place the plates in a concentrated manner, allowing the gripping mechanism 5 to perform plate gripping actions in the same lateral position. This facilitates the automatic control of the gripping mechanism 5 in gripping the plates and improves the efficiency of plate transportation.

[0068] Furthermore, the frame 1 has a notch on one side adjacent to the feeding rack for the feeding rack to pass through, and the bottom of the feeding rack is equipped with casters. In this way, the feeding rack can be moved in or out of the frame 1 manually, which facilitates the manual addition of boards to be heat-pressed in batches, saving time and labor.

[0069] In summary, the sheet metal conveying device for the hot press provided in this application has the following main advantages:

[0070] (1) Automated positioning of sheet material: The moving distance of the sheet material is controlled by a laser sensor so that the sheet material can be accurately stopped at the designated position, eliminating human error. The positioning accuracy can be improved to ±1mm and the scrap rate can be reduced to below 2%.

[0071] (2) Laser-guided manual film laying in real time: the surface film alignment time can be shortened by 50% (actual measurement reduced from 120 seconds to 60 seconds).

[0072] (3) Adapt to different specifications of sheet metal: The laser beam position can be adjusted to adapt to different specifications of sheet metal, and the production line switching efficiency can be improved by 70%.

[0073] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The above provides a detailed description of a sheet metal conveying device for a hot press provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
