[0052] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0053] As shown in Figures 1 to 6 The utility model embodiment provides a pressing plate structure 10, which comprises a guiding assembly 1, a bottom plate 2, a floating assembly 3 and a material loading plate 4, the guiding assembly 1 is rotationally connected to the bottom plate 2, and the floating assembly 3 is floatingly installed on the bottom plate 2. The material loading plate 4 can reciprocate between the guiding assembly 1 and the floating assembly 3, and the material loading plate 4 is in rolling contact with the guiding assembly 1, and the material loading plate 4 is in sliding contact with the floating assembly 3.

[0054] The floating assembly 3 can form a gap between the material loading plate 4 and the bottom plate 2.

[0055] The material loading plate 4 is used for carrying the material to be pressed 20. The material to be pressed 20 can be multilayer PCB material.

[0056] The utility model embodiment provides a pressing plate structure 10, which comprises a guiding assembly 1, a bottom plate 2, a floating assembly 3 and a material loading plate 4, the guiding assembly 1 is rotationally connected to the bottom plate 2, and the floating assembly 3 is floatingly installed on the bottom plate 2. The material loading plate 4 can reciprocate between the guiding assembly 1 and the floating assembly 3, and the material loading plate 4 is in rolling contact with the guiding assembly 1, and the material loading plate 4 is in sliding contact with the floating assembly 3.

[0057] In an embodiment, as shown in Figures 1 to 6 The guide assembly 1 is arranged on one side of the base plate 2 along a first direction x, and the rotation axis of the guide assembly 1 extends along a second direction y. The carrier tray 4 can reciprocate along the first direction x between the guide assembly 1 and the floating assembly 3.

[0058] The floating assembly 3 can form a gap between the carrier tray 4 and the base plate 2 along a third direction z.

[0059] The first direction x, the second direction y and the third direction z are perpendicular to each other.

[0060] By arranging the guide assembly 1 on one side of the base plate 2 along the first direction x, the carrier tray 4 can reciprocate along the first direction x between the guide assembly 1 and the floating assembly 3. During the movement of the carrier tray 4 along the first direction x, the rotation axis of the guide assembly 1 extends along the second direction y which is perpendicular to the first direction x, so as to ensure the rolling contact between the carrier tray 4 and the guide assembly 1 and reduce the abrasion of the carrier tray 4 by the guide assembly 1.

[0061] In addition, the floating assembly 3 can form a gap between the carrier tray 4 and the base plate 2 along the third direction z, so as to reduce the abrasion between the carrier tray 4 and the base plate 2.

[0062] In an embodiment, as shown in Figures 1 to 6 The guide assembly 1 comprises a first guide rod 11 and a second guide rod 12 which are arranged along the second direction y and are respectively rotatably connected to the base plate 2.

[0063] The rotation axis of the first guide rod 11 is collinear with the rotation axis of the second guide rod 12.

[0064] The carrier tray 4 is in rolling contact with the first guide rod 11 and the second guide rod 12.

[0065] The first guide rod 11 and the second guide rod 12 are arranged along the second direction y and are in rolling contact with the carrier tray 4, so as to support the carrier tray 4 at multiple points and make the movement of the carrier tray 4 more stable and avoid the carrier tray 4 from overturning.

[0066] In an embodiment, as shown in Figures 1 to 6 The cross section of the first guide rod 11 perpendicular to the second direction y is circular, and the cross section diameter of the first guide rod 11 gradually increases from the end close to the second guide rod 12 to the end away from the second guide rod 12.

[0067] The cross section of the second guide rod 12 perpendicular to the second direction y is circular, and the cross section diameter of the second guide rod 12 gradually increases from the end close to the first guide rod 11 to the end away from the first guide rod 11.

[0068] At this time, the first guide rod 11 and the second guide rod 12 can be symmetrically arranged, and the first guide rod 11 and the second guide rod 12 will form a transmission surface with low middle and high ends. When the material 20 to be pressed is relatively heavy and causes the material carrier plate 4 to deform, the transmission surface will better fit the material carrier plate 4, so that the contact area between the material carrier plate 4 and each guide rod is larger, so as to reduce the stress generated when the material carrier plate 4 contacts each guide rod, and further reduce the wear of the material carrier plate 4.

[0069] In an embodiment, as shown in Figures 1 to 6 The pressing plate structure 10 further includes a guide support assembly 5, the guide support assembly 5 is installed on the bottom plate 2, and the guide assembly 1 is rotatably connected to the guide support assembly 5, so as to realize the rotatable connection of the guide assembly 1 relative to the bottom plate 2.

[0070] In an embodiment, as shown in Figures 1 to 6 The guide support assembly 5 includes a first support seat 51, a second support seat 52, and a third support seat 53, the first support seat 51, the second support seat 52, and the third support seat 53 are spaced apart and installed on the bottom plate 2 along the second direction y, the first guide rod 11 is rotatably connected between the first support seat 51 and the second support seat 52, and the second guide rod 12 is rotatably connected between the second support seat 52 and the third support seat 53.

[0071] By rotatably connecting the first guide rod 11 between the first support seat 51 and the second support seat 52 and rotatably connecting the second guide rod 12 between the second support seat 52 and the third support seat 53, the rotatable connection between each guide rod and each support seat is realized, and the rotatable connection of the guide assembly 1 on the guide support assembly 5 is realized.

[0072] In an embodiment, each support seat (the first support seat 51, the second support seat 52, and the third support seat 53) can be rotatably connected to the bottom plate 2 by a locking bolt.

[0073] In an embodiment, as shown in Figure 6 The first guide rod 11 is rotatably connected between the first support seat 51 and the second support seat 52, and the second guide rod 12 is rotatably connected between the second support seat 52 and the third support seat 53.

[0074] The first support seat 51 is provided with a first adapter hole 511, the second support seat 52 is provided with a second adapter hole and a third adapter hole, and the third support seat 53 is provided with a fourth adapter hole.

[0075] The first adapter hole 511 is rotatably connected to the first adapter hole 511, the second adapter hole is rotatably connected to the second adapter hole, the third adapter hole is rotatably connected to the third adapter hole, and the fourth adapter hole is rotatably connected to the fourth adapter hole, so as to realize the rotatable connection between each guide rod and each support seat.

[0076] In an embodiment, as shown in Figure 6 The first support base 51 is provided with a first flat key mounting groove 512 near one side of the base plate 2, and the base plate 2 is provided with a second flat key mounting groove 21 near one side of the first support base 51.

[0077] The guide support assembly 5 further comprises a flat key 54, one end of which is inserted into the first flat key mounting groove 512, and the other end of which is inserted into the second flat key mounting groove 21.

[0078] By providing a flat key mounting groove on the first support base 51 and the base plate 2 respectively, and inserting the flat key 54 between the two flat key mounting grooves, the shear force generated by the material carrying disc 4 carrying the material to be pressed between the first support base 51 and the base plate 2 can be absorbed by the flat key 54.

[0079] In an embodiment, as shown in Figure 4 The floating assembly 3 comprises a support 31, an elastic member 32, and a connecting member 33, the connecting member 33 passes through the support 31 and is connected to the base plate 2, and the elastic member 32 is elastically supported between the support 31 and the base plate 2.

[0080] The material carrying disc 4 is in sliding contact with the side of the support 31 away from the base plate 2.

[0081] When the material carrying disc 4 carrying the material to be pressed moves, it will contact the end of the support 31. Due to gravity, the elastic member 32 between the support 31 and the base plate 2 will be elastically deformed, and the elastic member 32 will generate a counteracting elastic force on the support 31, so that the support 31 supports the material carrying disc 4, and the relative sliding between the material carrying disc 4 and the support 31 is sliding friction.

[0082] At the same time, the elastic member 32 will keep the material carrying disc 4 at a certain distance from the base plate 2 during movement. This arrangement can reduce the wear of the base plate 2, thereby reducing the maintenance and replacement cost of the equipment, and also reducing the production cost of the PCB and improving the production efficiency.

[0083] In an embodiment, the support 31 can be made of a high-strength and wear-resistant steel plate. At the same time, the surface of the support 31 can be nickel-plated and subjected to high-temperature treatment, so that the support 31 can still maintain its hardness and wear resistance in a high-temperature environment, thereby reducing wear and prolonging the service life of the pressing plate structure 10.

[0084] In an embodiment, as shown in Figure 4 The connecting member 33 can pass through the support 31 and the elastic member 32 in sequence and be connected to the base plate 2, so as to fix the position of the elastic member 32 along the first direction x and the second direction y while connecting the support 31 and the base plate 2.

[0085] In an embodiment, as shown in Figure 4 The elastic member 32 can be a spring structure, and the elastic member 32 can include a first elastic support portion 321, a first elastic connecting portion 322, a second elastic support portion 323, a second elastic connecting portion 324, and a third elastic support portion 325 connected in sequence. The first elastic support portion 321 and the third elastic support portion 325 abut against the bottom plate 2, the second elastic support portion 323 abuts against the support member 31, and the first elastic connecting portion 322 and the second elastic connecting portion 324 can elastically deform.

[0086] The connecting member 33 is connected to the bottom plate 2 through the support member 31 and the second elastic support portion 323 in sequence.

[0087] In this way, the elastic member 32 abuts against the support member 31 through the second elastic support portion 323 and abuts against the bottom plate 2 through the first elastic support portion 321 and the third elastic support portion 325. When the material loading plate 4 carries the material to be pressed 20, the elastic member 32 can elastically deform through the first elastic connecting portion 322 and the second elastic connecting portion 324 to support the support member 31.

[0088] In other embodiments not shown in the drawings, the first elastic support portion and the third elastic support portion can abut against the support member, and the second elastic support portion can abut against the bottom plate to achieve elastic support of the elastic member between the support member and the bottom plate. Alternatively, the elastic member can also be selected from other elastic structures such as springs, rubber pads, etc.

[0089] In an embodiment, as shown in Figures 1 to 3 In the same floating assembly 3, multiple elastic members 32 can be provided, and multiple connecting members 33 can be provided, and the multiple elastic members 32 and the multiple connecting members 33 are one-to-one corresponding.

[0090] By providing multiple connecting members 33, multiple-point connection between the support member 31 and the bottom plate 2 can be achieved. At the same time, by providing multiple elastic members 32 and one-to-one corresponding the multiple elastic members 32 and the multiple connecting members 33, the support member 31 and the bottom plate 1 can be elastically supported from multiple positions, and the support member 31 can also support the material loading plate 4 more stably.

[0091] In an embodiment, as shown in Figure 4 The support member 31 is provided with an inclined surface 311 near one end of the guide assembly 1, and the distance between the inclined surface 311 and the bottom plate 2 gradually increases from the side close to the guide assembly 1 to the side away from the guide assembly 1.

[0092] By setting the inclined surface 311 on the support 31 close to one end of the guide assembly 1, the tray 4 is first contacted with the inclined surface 311 during the movement of the tray 4 by the guide assembly 1 to the floating assembly 3, and then the tray 4 is stably moved to the support 31 through the sliding cooperation of the inclined surface 311 with the tray 4.

[0093] In an embodiment, as shown in Figure 4 , the bottom plate 2 is provided with a receiving groove 22, the elastic member 32 is received in the receiving groove 22, and the support 31 is partially received in the receiving groove 22. Preferably, the receiving groove 22 is provided extending along the third direction z.

[0094] By setting the receiving groove 22 to partially receive the support 31, the position of the support 31 along the first direction x and the second direction y can be limited, so that the support 31 can only move along the third direction z.

[0095] In an embodiment, as shown in Figures 1 to 3 , the support 31 extends along the first direction x. At this time, the support 31 can be a strip-shaped structure, and correspondingly, the receiving groove 22 can be provided as a long strip-shaped groove.

[0096] The floating assembly 3 is provided with a plurality of floating assemblies 3, and the plurality of floating assemblies 3 are sequentially and spacedly arranged along the second direction y to match a wider tray 4 along the second direction y.

[0097] By extending the support 31 along the first direction x and sequentially and spacedly arranging the plurality of floating assemblies 3 along the second direction y, a larger bearing surface can be formed by the support 31 of each floating assembly 3 to bear a larger size tray 4. In addition, the stress of the tray 4 can be dispersed to each support 31 and the corresponding elastic member 32, so as to reduce the stress of each support 31 and the corresponding elastic member 32.

[0098] In an embodiment, as shown in Figure 3 , the bottom plate 2 is provided with a liquid flow channel 23, a liquid outlet 24, and a liquid inlet 25, the liquid flow channel 23 is located in the bottom plate 2, and the liquid flow channel 23 is used to flow a heat-conducting medium or a cooling medium.

[0099] The liquid outlet 24 and the liquid inlet 25 are respectively communicated with the liquid flow channel 23.

[0100] By setting up a liquid flow channel 23 and connecting the liquid outlet 24 and the liquid inlet 25, the flow of a heat-conducting medium or a cooling medium is achieved. When a heat-conducting medium (such as heat-conducting oil or other heat-conducting media) flows through the liquid flow channel 23, the base plate 2 will be used as a heating plate. During the flow of the heat-conducting medium through the liquid flow channel 23, the heat of the heat-conducting medium can be transferred to the material to be pressed 20 through heat exchange, achieving hot pressing. When a cooling medium (such as coolant or other cooling media) flows through the liquid flow channel 23, the base plate 2 will be used as a cooling plate. During the flow of the cooling medium through the liquid flow channel 23, the heat of the material to be pressed 20 can be transferred to the cooling medium through heat exchange, achieving cold pressing.

[0101] The working principle of the pressure plate structure provided in this embodiment of the utility model is as follows:

[0102] (1) The process of the material to be pressed 20 entering the laminating equipment along with the loading tray 4.

[0103] When the material to be pressed 20 enters the laminating equipment along with the loading tray 4, such as Figure 5 As shown, the bottom of the material tray 4 first contacts two symmetrically distributed guide rods (first guide rod 11 and second guide rod 12). At this time, part of the weight of the material tray 4 is transmitted to each support seat (first support seat 51, second support seat 52 and third support seat 53) through the two guide rods. Simultaneously, the material tray 4 will drive the two guide rods to rotate. During this process, the weight transmitted to the first support seat 5 will be transmitted to the base plate 2 through the locking bolt and the flat key 54.

[0104] As the material to be pressed 20 continues to move along with the loading tray 4, it will come into contact with the end of the support member 31. Due to gravity, the elastic member 32 below the support member 31 will undergo elastic deformation, generating a reaction force on the support member 31, so that the support member 31 supports the loading tray 4. During this process, relative sliding occurs between the support member 31 and the loading tray 4, which is called sliding friction.

[0105] When the material to be pressed 20 moves completely above the floating component 3 and the base plate 2 along with the material tray 4, the supporting force generated by the numerous elastic elements 32 distributed on the base plate 2 can overcome the gravity of the material to be pressed 20, so that the material tray 4 will maintain a certain distance from the base plate 2 under the action of the support 31.

[0106] During the process of the material to be pressed 20 moving from the guide assembly 1 to the floating assembly 3 and the base plate 2 along with the material tray 4, since the top surface of each guide rod is slightly higher than the upper surface of the base plate 2, and the upper surface of the support 31 is also slightly higher than the upper surface of the base plate 2, and due to the reaction force generated by the elastic element 32, the material to be pressed 20 and the material tray 4 cannot directly contact the base plate 2. In other words, the base plate 2 and the material tray 4 always maintain a certain gap.

[0107] (3) the process that the material to be pressed 20 exits the laminating equipment with the carrier disc 4.

[0108] The process that the material to be pressed 20 exits the laminating equipment with the carrier disc 4 is opposite to the process that the material to be pressed 20 enters the laminating equipment with the carrier disc 4, which will not be repeated here.

[0109] The laminating equipment provided by the embodiment of the utility model comprises the pressing plate structure 10.

[0110] The laminating equipment provided by the embodiment of the utility model comprises the pressing plate structure 10.

[0111] In an embodiment, the laminating equipment can be a cold press or a hot press.

[0112] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
