Description

Technical Field

[0001] This application relates to the field of printed circuit board manufacturing technology, specifically to a hot press plate and hot press equipment. Background Technology

[0002] In the lamination process of printed circuit boards, a carrier tray is typically used to hold the stacked materials, which are then transferred to a hot press plate for thermoforming. However, during loading, the carrier tray and the hot press plate are in direct contact and relative sliding friction occurs, which can easily damage the surfaces of both the carrier tray and the hot press plate, thus shortening their service life. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the main objective of this application is to provide a hot press plate and hot press equipment that can reduce the damage to the surface of the bearing plate and the hot press plate during feeding, so as to extend the service life of the bearing plate and the hot press plate.

[0004] This application also proposes a hot pressing device including the aforementioned hot pressing plate.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: According to a first aspect of the embodiments of this application, a hot press plate is provided, including a body, an elastic component, and a rolling component; Along the thickness direction, the body includes a mounting hole with an opening on the surface of the body; The flexible component is disposed within the mounting hole; The rolling assembly includes a slider and a rolling element. Along the thickness direction, the slider is slidably connected to the body, and the slider and the rolling element are connected. The rolling element is used to make rolling contact with the workpiece carried by the body. The elastic component can move along the thickness direction under the action of external force, so that the rolling element has a first state and a second state. In the first state, the rolling element can be received in the mounting hole by compressing the elastic component. In the second state, the rolling element can be supported by the rebound of the elastic component and retain at least a portion of the surface that extends beyond the body.

[0006] The hot press plate according to the embodiments of this application has at least the following beneficial effects: During loading, the rolling element can be supported by the elastic component to maintain at least a portion of its surface extending beyond the body. This allows the rolling element to roll into contact with the workpiece to be carried, transforming the relative sliding between the workpiece and the body into rolling. The workpiece to be carried can be a support plate. This reduces damage caused by relative friction between the support plate and the hot press plate, extending their service life. Furthermore, the rolling element's support ensures a certain distance between the workpiece and the hot press plate before hot pressing, effectively preventing premature heating of the workpiece and its impact on lamination quality. Additionally, during pressing, the rolling element compresses the elastic component, allowing it to move along the thickness direction and be housed within the mounting hole. This solves the problem of the rolling component affecting the flatness of the contact surface between the hot press plate and the support plate during hot pressing, ensuring uniform pressure and heat transfer during the hot pressing process and thus guaranteeing lamination quality. Optionally, the elastic component includes a connector and an elastic element. The connector is detachably connected to the wall of the mounting hole. Along the thickness direction, one end of the elastic element is connected to the connector, and the other end of the elastic element is connected to the rolling element.

[0007] Optionally, the connector includes a connecting portion and a guide portion. The connecting portion is detachably connected to the wall of the mounting hole. Along the thickness direction, the guide portion is connected to the side of the connecting portion facing the rolling element, and the elastic element is arranged around the outer peripheral wall of the guide portion.

[0008] Optionally, in the second state, the distance between the slider and the guide in the thickness direction is greater than the protrusion of the rolling element beyond the body.

[0009] Optionally, the mounting hole extends through the body.

[0010] Optionally, the rolling element includes a rolling portion and a carrier shaft portion, the carrier shaft portion being arranged vertically along the thickness direction, and at least one of the rolling portion and the sliding element being rotatably connected to the carrier shaft portion, and the rolling portion and the sliding element being rotatably connected about the thickness direction.

[0011] Optionally, the rolling part and the sliding part are arranged at intervals along the extension direction of the bearing shaft.

[0012] Optionally, the body is provided with multiple mounting holes, which are arranged at intervals, and at least three mounting holes are provided at intervals along the length and / or width of the body.

[0013] Optionally, the body includes a central support area and an outer support area, with the outer support area arranged around the central support area, and multiple mounting holes provided in both the central support area and the outer support area.

[0014] According to a second aspect of the embodiments of this application, a hot pressing device is provided, including a hot pressing plate in any of the above embodiments, the hot pressing plate being arranged at a hot pressing station.

[0015] The hot pressing equipment according to the embodiments of this application has at least the following beneficial effects: by using the hot pressing plate in any of the above embodiments, the hot pressing equipment can effectively reduce the wear between the bearing plate and the hot pressing plate, thereby extending the service life of the bearing plate and the hot pressing plate. At the same time, during the hot pressing process, the interference of the rolling components on the contact between the hot pressing plate and the bearing plate is avoided, ensuring that the pressure applied by the hot pressing plate can be evenly transmitted to the bearing workpiece, which helps to improve the hot pressing quality.

[0016] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The embodiments of this application are described below with reference to the accompanying drawings: refer to Figures 1 to 4According to a first aspect of the embodiments of this application, a hot press plate is provided, the hot press plate including a body 100, an elastic component 200, and a rolling component 300. Along the thickness direction, the body 100 includes a mounting hole 110 opening on the surface of the body 100, the mounting hole 110 for receiving the elastic component 200 and the rolling component 300. The elastic component 200 is disposed within the mounting hole 110, and it is understood that the elastic component 200 can be connected to the hole wall of the mounting hole 110. The elastic component 200 is configured such that at least a portion of the elastic component 200 can undergo elastic deformation, that is, a portion of the elastic component 200 can undergo elastic deformation, or the entire elastic component 200 can undergo elastic deformation, so as to ensure that the rolling component 320 can compress the elastic component 200, and that the elastic component 200 rebounds to support the rolling component 320.

[0025] The rolling assembly 300 may further include a slider 310 and a rolling element 320. Along the thickness direction, the slider 310 is slidably connected to the body 100, and the slider 310 is connected to the rolling element 320 to drive the rolling element 320 to slide relative to the body 100. The rolling element 320 is used to make rolling contact with the workpiece carried by the body 100, so that the relative movement between the workpiece carried by the body 100 and the rolling element 320 is rolling, thereby reducing friction loss.

[0026] The elastic component 200 can move along the thickness direction under the action of external force, so that the rolling component 320 has a first state and a second state. The rolling component 320 has different positions in the first state and the second state. Specifically, in the first state, the rolling component 320 can compress the elastic component 200 and be housed in the mounting hole 110 to ensure the fit between the workpiece and the hot press plate, thereby ensuring the hot pressing quality. In the second state, the rolling component 320 can be supported by the rebound of the elastic component 200 and maintain at least a portion of its surface beyond the body 100 so that the rolling component 320 can roll into contact with the workpiece carried by the body 100. The workpiece can be carried by the support plate. Thus, during loading, the rolling component 320 supports the support plate and maintains a distance from the hot press plate, and the support plate and the rolling component 320 roll into contact, thereby realizing the relative rolling between the support plate and the hot press plate during loading, thereby reducing the friction loss caused by the relative movement between the support plate and the hot press plate, which is beneficial to extending the service life of the support plate and the hot press plate.

[0027] The aforementioned elastic component 200 may include a structure with elastic deformation, such as a helical spring, a disc spring, or an elastic rubber block. Taking a helical spring as an example, one end of it can be fixed in the mounting hole 110, and the other end is connected to the sliding member 310. When the rolling member 320 is subjected to the pressure of the workpiece, the helical spring can be compressed along the thickness direction to realize the switching from the second state to the first state, so as to facilitate hot pressing. When the pressure applied to the rolling member 320 decreases to less than the rebound force of the helical spring, the helical spring can rely on its own elasticity to restore its original shape, push the sliding member 310 to move along the thickness direction, and then the sliding member 310 drives the rolling member 320 to return to the position exposed in the mounting hole 110, completing the switching from the first state to the second state, so as to meet the requirement that the rolling component 300 needs to realize the state switching through elastic deformation.

[0028] The rolling element 320 of the aforementioned rolling assembly 300 can adopt structures such as balls, rollers, or needle rollers to ensure that the rolling element 320 can roll relative to the body 100. For example, the sliding element 310 can be a cage, and the rolling element 320 can be a ball. The ball can be rotatably connected to the body 100 through the cage, and the cage can be movably connected to the body 100 along the thickness direction. The connection can be achieved through a sliding groove structure, the cooperation of guide posts and guide holes, etc. In addition, the cage is connected to the elastic component 200. When the bearing plate and the hot press plate move relative to each other, the ball is exposed in the mounting hole 110 and contacts the bottom wall of the bearing plate, converting the relative sliding between the bearing plate and the hot press plate into rolling. When the bearing plate carries the workpiece and moves to the preset hot press position, the workpiece is hot pressed. Under the action of pressure, the ball can drive the cage to move along the thickness direction, so that the cage compresses the elastic component 200. Finally, the ball is housed in the mounting hole 110, realizing the avoidance of the bearing plate and the hot press plate from sticking together.

[0029] refer to Figures 2 to 4 Specifically, during loading, the rolling element 320 is in the second state, and the bearing plate carrying the workpiece moves toward the hot press plate arranged in the hot press station. The rolling element 320 extends beyond the surface of the body 100 to support the bearing plate. The rolling element 320 and the bearing plate roll in contact, avoiding relative friction between the bottom of the bearing plate and the body 100, effectively reducing the damage caused by relative friction between the bearing plate and the hot press plate, and making the positioning accuracy of the bearing plate relative to the hot press plate more accurate.

[0030] Furthermore, when the bearing plate is supported by the rolling element 320 and rolls relative to the hot press plate, there is a gap between the bearing plate and the body 100. The height of this gap is the height of the rolling element 320 above the surface of the body 100. This gap can ensure that the workpiece to be pressed is not heated in advance before hot pressing, so that the workpiece to be pressed can undergo cross-linking reaction during pressing, and the cross-linking reaction is avoided in advance, which is beneficial to improving the lamination quality.

[0031] When the carrier plate moves to the preset hot pressing position between the upper and lower hot pressing plates, the upper and lower hot pressing plates approach each other to press the workpiece. As a result, the pressure applied by the carrier plate to the rolling element 320 increases further. The rolling element 320 and the sliding element 310 slide synchronously relative to the body 100 along the thickness direction. Then, the sliding element 310 further compresses the elastic component 200 until the rolling element 320 switches from the second state to the first state, that is, is housed in the mounting hole 110. The heat conduction from the hot pressing plate to the carrier plate is more uniform, which is beneficial to ensuring the lamination quality.

[0032] refer to Figures 2 to 4 The aforementioned elastic component 200 may include a connector 210 and an elastic element 220. The connector 210 is detachably connected to the wall of the mounting hole 110. Along the thickness direction, one end of the elastic element 220 is connected to the connector 210, and the other end of the elastic element 220 is connected to the rolling element 320. The elastic element 220 may be a spring, an elastic block, or other structure with elastic deformation capability. The connection method between the connector 210 and the wall of the mounting hole 110 may be a threaded connection, a snap-fit ​​connection, or other connection methods. Taking the threaded connection between the connector 210 and the wall of the mounting hole 110 as an example, the inner side of the wall of the mounting hole 110 is machined with an internal thread, and the outer side of the connector 210 is machined with an external thread that matches the internal thread. The connector 210 is provided with a hexagonal groove, a cross groove, or a slotted groove, etc., and is screwed into the mounting hole 110 to achieve connection with the wall of the mounting hole 110. The axial position of the connector 210 within the mounting hole 110 can be adjusted by rotating the connector 210.

[0033] Understandably, in the second state, the rolling element 320 protrudes from the mounting hole 110 to support the carrier plate and maintain a distance from the hot press plate. For workpieces of different weights, the force applied to the rolling element 320 is different, resulting in different degrees of compression of the elastic element 220. Therefore, by adjusting the position of the connecting element 210, the height of the rolling element 320 protruding from the surface of the body 100 can be adjusted, avoiding friction when the carrier plate and the hot press plate move relative to each other, thus adapting to support workpieces of different weights. For example, the elastic element 220 is connected to the sliding element 310, which, while transmitting force, restricts the sliding element 310 from disengaging from the mounting hole 110, ensuring the connection between the sliding element 310 and the body 100. The position of the connecting element 210 can be adjusted from the connecting element 210. When the rolling element 320 does not support the bearing plate, if the connecting element 210 is adjusted to be directed into the mounting hole 110, the rolling element 320 can adapt to bearing a heavier workpiece while maintaining the same height above the surface of the body 100. Alternatively, the rolling element 320 can increase the gap between the bearing plate and the body 100 while maintaining the same load, which is beneficial to improving the adaptability of the hot press plate to workpieces with different loads.

[0034] Another possible implementation is that, in the vertical direction along the thickness direction, the mounting hole 110 is provided with a limiting protrusion, and the sliding member 310 is restricted from disengaging from the mounting hole 110 by the limiting protrusion. Based on this, the outward protrusion height of the rolling member 320 can also be adjusted by adjusting the position of the connecting member 210.

[0035] refer to Figures 2 to 4 The aforementioned connector 210 may further include a connecting portion 211 and a guide portion 212. The connecting portion 211 is detachably connected to the wall of the mounting hole 110. Along the thickness direction, the guide portion 212 is connected to the side of the connecting portion 211 facing the rolling element 320, and the elastic element 220 is arranged around the outer peripheral wall of the guide portion 212. It can be understood that the connector 210 is in the shape of a stepped cylinder.

[0036] Specifically, the outer peripheral wall of the connecting part 211 is machined with external threads, and the inner side of the mounting hole 110 is machined with internal threads that match the external threads. The connecting part 211 is detachably connected to the mounting hole 110 through thread engagement. The axial position of the connecting part 211 in the mounting hole 110 can be adjusted by rotating the connecting part 211. The guide part 212 has a cylindrical structure. The elastic element 220 can be a spring or an annular elastic rubber block. The elastic element 220 is arranged around the outer peripheral wall of the guide part 212. Along the thickness direction, one end of the elastic element 220 can be connected to the side of the connecting part 211 facing the rolling element 320, and the other end of the elastic element 220 can be connected to the sliding element 310. The guide part 212 is used to provide guidance for the compression of the elastic element 220 to limit the vertical deformation of the elastic element 220 along the thickness direction, and the transmission of elastic force is more stable.

[0037] refer to Figures 2 to 4 In the second state, along the thickness direction, the distance between the slider 310 and the guide 212 is greater than the protrusion of the rolling element 320 beyond the body 100, so as to ensure that the rolling element 320 can be accommodated inside the mounting hole 110 in the first state.

[0038] refer to Figures 2 to 4In the above embodiment, the mounting hole 110 can penetrate the body 100, that is, the mounting hole 110 on the body 100 is a through hole, penetrating the two opposite surfaces of the body 100 along the thickness direction, so that the elastic component 200 and the rolling component 300 can be respectively installed in the mounting hole 110 from both ends along the thickness direction. After assembly, the position of the elastic component 200 in the mounting hole 110 can be adjusted from the end where the elastic component 200 is installed, thereby adjusting the elastic compression of the elastic component 200 in the first state, or the height of the rolling component 320 beyond the surface of the body 100 in the second state. Thus, while ensuring the switching between the first state and the second state, the elastic force transmitted by the elastic component 200 to the bearing plate through the rolling component 300 can be reduced, which is beneficial to reducing the risk of deformation of the bearing plate due to excessive local stress, and also taking into account the adaptability to bearing different workpieces.

[0039] Specifically, as in the above embodiment, the elastic component 200 may include a connector 210 and an elastic element 220. The connector 210 is threadedly connected to the wall of the mounting hole 110. By rotating the thread, the position of the connector 210 within the mounting hole 110 can be adjusted along the thickness direction. When it is necessary to adjust the compression of the elastic element 220 in the first state, the position of the connector 210 can be directly adjusted from the end away from the rolling component 300, making the adjustment more convenient. That is, while ensuring that the rolling component 300 is at least partially exposed in the mounting hole 110 in the second state, the compression of the elastic element 220 in the first state is smaller, thereby reducing the force transmitted by the elastic element 220 to the bearing plate through the rolling component 300, and thus reducing the local stress on the bearing plate during hot pressing. It should be understood that the through-hole mounting hole 110 makes adjustment easier without removing the rolling component 300, which helps to improve the adaptability of the hot press plate to different working conditions.

[0040] refer to Figures 2 to 4 The aforementioned rolling element 320 may include a rolling portion 321 and a carrier shaft portion 322. The carrier shaft portion 322 extends vertically along the thickness direction. At least one of the rolling portion 321 and the sliding element 310 is rotatably connected to the carrier shaft portion 322. The rolling portion 321 and the sliding element 310 are rotatably connected about the thickness direction. The rolling portion 321 may be a roller. For example, along the rotation axis of the rolling portion 321, the sliding element 310 is provided with two parallel and spaced mounting ears. The two mounting ears are respectively provided with coaxial shaft holes. The axis of the shaft holes is perpendicular to the thickness direction. The two ends of the rolling portion 321 are provided with cylindrical shaft heads. The diameter of the shaft head matches the inner diameter of the shaft hole. The shaft head is inserted into the shaft hole to form a clearance fit, thereby realizing the rotatable connection between the rolling portion 321 and the sliding element 310 about the thickness direction.

[0041] Along the thickness direction, the rolling part 321 extends beyond the surface of the slider 310 on the side opposite to the elastic component 200. The slider 310 is connected to the elastic component 200, and the elastic force provided by the elastic component 200 can be transmitted to the rolling part 321 through the slider 310. In the first state, the rolling part 321 is located inside the mounting hole 110. In the second state, a part of the rolling part 321 extends beyond the surface of the body 100, that is, it is exposed outside the mounting hole 110. The exposed part of the rolling part 321 can contact the carrier plate, so that the movement direction of the carrier plate is guided by the rolling direction of the rolling part 321, thereby effectively preventing the carrier plate from deviating to other directions during movement, and thus ensuring the accuracy of the loading position of the carrier plate.

[0042] refer to Figure 4 Along the extending direction of the bearing shaft portion 322, the rolling portion 321 and the sliding member 310 in the above embodiment are arranged at intervals, which can prevent the rolling portion 321 from contacting the mounting ears of the sliding member 310 during rotation, so that the bearing plate and the hot press plate move more smoothly. At the same time, it also helps to reduce the wear rate of the rolling member 320 and the sliding member 310 and extend the service life of the rolling assembly 300.

[0043] refer to Figures 1 to 3 The aforementioned body 100 may be provided with a plurality of mounting holes 110, each mounting hole 110 being arranged at intervals, and along the length direction and / or width direction of the body 100, the body 100 is provided with at least three mounting holes 110 at intervals, and each mounting hole 110 is provided with the elastic component 200 and the rolling component 300 in the above embodiment.

[0044] One possible implementation is that the body 100 can be a rectangular plate structure with multiple mounting holes 110. Each mounting hole 110 penetrates two opposite surfaces of the body 100 along the thickness direction. The mounting holes 110 are spaced apart. At least three mounting holes 110 are spaced apart along the length direction of the body 100, and / or at least three mounting holes 110 are spaced apart along the width direction of the body 100, forming an array layout with the mounting holes 110 in the length direction. The multiple mounting holes 110 can provide more stable support for the support plate and distribute the support force to the location of each mounting hole 110, so as to more evenly support the body 100, which is beneficial to ensuring the integrity of the support plate.

[0045] It should be noted that, along the length and / or width of the body 100, the body 100 is provided with at least three mounting holes 110 at intervals. This can be understood as, along the extension direction of the narrowest side dimension of the bearing plate or hot press plate, the interval between two adjacent mounting holes 110 is ≤ 1 / 3 of the narrowest side dimension of the body 100.

[0046] refer to Figures 1 to 3The aforementioned body 100 may include a central support area and an outer support area, with the outer support area arranged around the central support area. Both the central support area and the outer support area are provided with multiple mounting holes 110.

[0047] Specifically, the central support area is located in the middle of the body 100, and the outer support area is arranged around the central support area. The central support area has four mounting holes 110, all of which are through holes. The four mounting holes 110 are connected in sequence to form a rectangle. The four sides of this rectangle are parallel to the length and width directions of the body 100, respectively, and the four mounting holes 110 are located at the four vertices of the rectangle. The outer support area also has four mounting holes 110, which are connected in sequence to form a larger rectangle. The larger rectangle is similar in shape to the rectangle of the central support area and their sides are parallel to each other. The larger rectangle is arranged around the smaller rectangle, and the centers of the larger and smaller rectangles coincide. This allows the center and edge of the support plate to receive symmetrical four-point support. When the support plate is placed, the symmetrically distributed support points ensure that the support force on each part of the support plate is more balanced, avoiding tilting of the support plate due to asymmetrical distribution of support points, and making the loading of the support plate more stable.

[0048] It should be noted that the above is only one arrangement of the mounting holes 110 in the embodiments of this application. The arrangement of the mounting holes 110 can be adjusted according to the actual needs such as the size and weight distribution of the carrier plate. For example, five mounting holes 110 can be connected in sequence to form a pentagon, or other numbers of mounting holes 110 can be connected in sequence to form other numbers of polygons, or each mounting hole 110 can be connected in sequence to form a circle. Different arrangements can adapt to different usage scenarios, and will not be described in detail here.

[0049] refer to Figures 1 to 8 According to a second aspect of the embodiments of this application, a hot pressing device is provided, including a hot pressing plate in any of the above embodiments. The hot pressing plate is used to be arranged at the hot pressing station. Specifically, the hot pressing device includes a frame, a hot pressing plate, a support plate, and a hot pressing plate. The frame is a frame structure used to support other components of the hot pressing device. The hot pressing plate is installed on the upper part of the frame. The hot pressing plate and the frame are connected by a lifting mechanism. The lifting mechanism can be a driving structure such as a hydraulic cylinder. Taking a hydraulic cylinder as an example, the cylinder body of the hydraulic cylinder is fixed on the frame, and the piston rod of the hydraulic cylinder is connected to the hot pressing plate. The extension and retraction of the piston rod drives the hot pressing plate to move in the vertical direction, thereby realizing the lifting and lowering of the hot pressing plate and pushing the support plate to move relative to the hot pressing plate.

[0050] The working process of the hot press equipment is as follows: After the workpiece to be laminated is placed on the carrier plate, the carrier plate is transferred to the hot press plate. At this time, the rolling element 320 of the hot press plate is in the second state. The rolling element 320 is exposed outside the mounting hole 110 and supports the carrier plate. The carrier plate can move smoothly between the upper and lower hot press plates under the rolling support of the rolling element 320. Then, the lifting mechanism drives the two hot press plates to approach each other, and the hot press plate contacts the carrier plate and applies pressure.

[0051] After the bearing plate is pressed, it pushes the rolling element 320 to move into the mounting hole 110. The elastic component 200 is further compressed, causing the rolling element 320 to switch to the first state, that is, the rolling element 320 is housed in the mounting hole 110. The hot press plate continues to descend and hot presses the workpiece on the bearing plate. After the hot pressing is completed, the lifting mechanism drives the two hot press plates to move away from each other. The elastic component 200 elastically rebounds and the rolling element 320 switches to the second state. The rolling element 320 is exposed in the mounting hole 110 and lifts the bearing plate to support the movement of the bearing plate and leave the hot pressing station.

[0052] Therefore, the hot pressing equipment of this application can effectively reduce the wear between the bearing plate and the hot pressing plate, thereby extending the service life of the bearing plate and the hot pressing plate. At the same time, during the hot pressing process, the interference of the rolling component 300 on the contact between the hot pressing plate and the bearing plate is avoided, ensuring that the pressure applied by the hot pressing plate can be evenly transmitted to the workpiece, which helps to improve the hot pressing quality of the workpiece.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
