[0002] In the manufacturing of high-end electronic products such as electronic control units for new energy vehicles, aluminum substrates are widely used as the core carrier, which needs to be reliably pressed during mounting, curing, and testing.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] In the description of this utility model, it should be noted that the terms "center," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] Please refer to Figure 1 This embodiment provides a substrate pressing device 100, including a drive rod 110 and a first pressure plate 120 and a second pressure plate 130 spaced apart on opposite sides of the drive rod 110. The first pressure plate 120 and the second pressure plate 130 are arranged opposite to each other and parallel to each other. The drive rod 110 is connected to the first pressure plate 120 and the second pressure plate 130 respectively through a linkage mechanism 140. The drive rod 110 is driven to move along a first direction A, and simultaneously drives the first pressure plate 120 and the second pressure plate 130 to move towards each other or away from each other along a second direction B through the linkage mechanism 140. The first direction A and the second direction B are perpendicular to each other. The side of the first pressure plate 120 and the second pressure plate 130 that is away from each other is a pressing surface 101 for bonding with the substrate 200.

[0025] like Figure 1 As shown, the substrate pressing device 100 includes a drive rod 110, pressure plates, and a linkage mechanism 140 connecting the drive rod 110 and the pressure plates. There are two pressure plates: a first pressure plate 120 and a second pressure plate 130, spaced apart on opposite sides of the drive rod 110, and parallel to each other, so that the pressing surfaces 101 of both pressure plates 120 and 130 can be tightly fitted to the substrate 200. The drive rod 110 simultaneously drives the first pressure plate 120 and the second pressure plate 130 to move towards or away from each other along a second direction B via the linkage mechanism 140, enabling the two pressure plates to simultaneously press the two substrates 200 against the housing 300 to which the substrates 200 need to be bonded. It should be noted that in another possible embodiment of this application, there may be only one pressure plate. The drive rod 110 drives the pressure plate to stick to the substrate 200 through the linkage mechanism 140, so that the substrate 200 is pressed against the housing 300 to which the substrate 200 needs to be pasted.

[0026] The drive rod 110 is driven to move along a first direction A, while the linkage mechanism 140 allows the force transmission direction to change from the first direction A to a second direction B, improving operational flexibility. Specifically, the first direction A is vertical, and the second direction B is horizontal. When the drive rod 110 moves downward, the first pressure plate 120 and the second pressure plate 130 move towards each other to move away from the substrate 200. At this time, the substrate pressing device 100 is in a tightened state, such as... Figure 6 As shown. When the drive rod 110 moves upward, the first pressure plate 120 and the second pressure plate 130 move in opposite directions to approach the substrate 200 until they are in close contact with the substrate 200. At this time, the substrate pressing device 100 is in the unfolded state, as shown. Figure 5 As shown. The drive mechanism for the movement of the drive rod 110 along the first direction A can be manual by an operator or electrically driven by an electric component; this application does not impose any restrictions on this.

[0027] The pressing surfaces 101 of the first pressure plate 120 and the second pressure plate 130 ensure a large contact area between the pressure plate and the substrate 200. The power of the drive rod 110 can be transmitted to the entire surface of the substrate 200 through the pressure plates via surface contact, reducing local stress concentration on the substrate 200 and lowering the risk of displacement or deformation of the substrate 200 due to uneven force during the pressing process. Simultaneously, the surface-to-surface contact method minimizes the possibility of metal fragments generated due to frequent screw removal and tightening in existing technologies, improving the reliability and safety of the pressing process. Furthermore, the linkage mechanism 140 simultaneously drives the first pressure plate 120 and the second pressure plate 130, enabling simultaneous pressing of two substrates 200, further improving clamping efficiency. Moreover, the surface-to-surface contact method eliminates the need to redesign the pressing device structure based on different product structures, improving versatility and reducing production costs. The aforementioned substrate pressing device 100 possesses good versatility and can improve the efficiency and reliability of substrate 200 pressing.

[0028] For example, such as Figure 2 As shown, the linkage mechanism 140 includes a first follower link 141, a second follower link 142, and a movable link 143 disposed at the end of the drive rod 110. The movable link 143 extends along a third direction C, which is perpendicular to the first direction A and the second direction B, respectively. One end of the first follower link 141 is hinged to the movable link 143, and the other end is hinged to the first pressure plate 120. One end of the second follower link 142 is hinged to the movable link 143, and the other end is hinged to the second pressure plate 130.

[0029] Specifically, such as Figure 2As shown, the moving link 143 is connected to the bottom of the drive rod 110, and the first follower link 141 and the second follower link 142 are respectively arranged along the second direction B. Both the first follower link 141 and the second follower link 142 are hinged to the moving link 143, so that an angle that can freely change is formed between the first follower link 141 and the second follower link 142. Since the first follower link 141 and the second follower link 142 are both connected to the same moving link 143, the synchronicity and symmetry of the movement of the first pressure plate 120 and the second pressure plate 130 can be guaranteed, solving the problems of uneven clamping force, offset or deformation of the base plate 200 caused by traditional screw-on tightening.

[0030] When the drive rod 110 drives the moving link 143 upward, the included angle between the first follower link 141 and the second follower link 142 increases. At this time, the straight-line distance between the hinge point of the first follower link 141 and the first pressure plate 120 and the hinge point of the second follower link 142 and the second pressure plate 130 increases. That is, the first pressure plate 120 and the second pressure plate 130 move in opposite directions to approach the substrate 200 until they are in close contact with the substrate 200. When the drive rod 110 drives the moving link 143 downward, the included angle between the first follower link 141 and the second follower link 142 decreases. At this time, the straight-line distance between the hinge point of the first follower link 141 and the first pressure plate 120 and the hinge point of the second follower link 142 and the second pressure plate 130 decreases. That is, the first pressure plate 120 and the second pressure plate 130 move in a direction closer to each other to separate from the substrate 200.

[0031] Since the drive rod 110 extends along the first direction A and the moving link 143 extends along the third direction C, the force can be transmitted from the drive rod 110 to the moving link 143, and then from the moving link 143 to the first follower link 141 and the second follower link 142, thereby driving the first pressure plate 120 and the second pressure plate 130 to move along the second direction B. This achieves efficient force transmission and flexible change of force direction while ensuring the compactness of the structure.

[0032] It should be noted that, as Figure 2 As shown, in a preferred embodiment of this application, there are two first follower links 141 and two second follower links 142, and the two first follower links 141 and the two second follower links 142 are symmetrically distributed on opposite sides of the moving link 143.

[0033] Specifically, such as Figure 2As shown, there are two first follower links 141, which are distributed along a third direction C on opposite sides of the moving link 143, located on opposite sides of the drive rod 110. Similarly, there are two second follower links 142, which are distributed along a third direction C on opposite sides of the moving link 143, located on opposite sides of the drive rod 110. Preferably, the end sidewalls of the first follower links 141 can be closely fitted to the end sidewalls of the second follower links 142 to improve motion stability.

[0034] This configuration allows the two first follower links 141 to be connected to both ends of the first pressure plate 120, and the two second follower links 142 to be connected to both ends of the second pressure plate 130. This distributes the clamping force evenly across the two points of the first pressure plate 120 and the second pressure plate 130, effectively preventing minor deformations or jamming that may occur on one side of the follower link 143 due to uneven force distribution, and ensuring the smooth movement of the pressure plate.

[0035] For example, such as Figure 2 As shown, the linkage mechanism 140 also includes a first fixed connecting rod 144, a first guide bracket 145, and a second guide bracket 146. The first fixed connecting rod 144 extends along a third direction C, and the end of the drive rod 110 away from the moving connecting rod 143 passes through the first fixed connecting rod 144. One end of the first guide bracket 145 is hinged to the first fixed connecting rod 144, and the other end is slidably connected to the first pressure plate 120 along a first direction A. The extension direction of the first guide bracket 145 intersects with the extension direction of the first follower connecting rod 141. One end of the second guide bracket 146 is hinged to the first fixed connecting rod 144, and the other end is slidably connected to the second pressure plate 130 along a first direction A. The extension direction of the second guide bracket 146 intersects with the extension direction of the second follower connecting rod 142.

[0036] Specifically, such as Figure 2 As shown, the first fixed link 144 is disposed along the third direction C at one end of the drive rod 110 away from the moving link 143. The drive rod 110 passes through the middle of the first fixed link 144. The first fixed link 144 can limit the movement of the drive rod 110, improve the stability of the movement of the drive rod 110, and reduce the possibility of the drive rod 110 shaking during movement.

[0037] The first guide bracket 145 and the second guide bracket 146 are respectively arranged along the second direction B. The first guide bracket 145 and the second guide bracket 146 are both hinged to the first fixed connecting rod 144 so that an angle that can be freely changed is formed between the first guide bracket 145 and the second guide bracket 146.

[0038] Since one end of the first guide bracket 145 is hinged to the first fixed connecting rod 144 and the other end is slidably connected to the first pressure plate 120, when an angle change occurs between the first guide bracket 145 and the second guide bracket 146, the end of the first guide bracket 145 can slide along the first direction A. Similarly, since one end of the second guide bracket 146 is hinged to the first fixed connecting rod 144 and the other end is slidably connected to the second pressure plate 130, when an angle change occurs between the first guide bracket 145 and the second guide bracket 146, the end of the second guide bracket 146 can slide along the first direction A.

[0039] When the drive rod 110 drives the connecting rod 143 to move upward, the first pressure plate 120 and the second pressure plate 130 move in opposite directions. At this time, the included angle between the first guide bracket 145 and the second guide bracket 146 increases. The end of the first guide bracket 145 slides on the surface of the first pressure plate 120 along the first direction A, and the end of the second guide bracket 146 slides on the surface of the second pressure plate 130 along the first direction A.

[0040] By providing the first guide bracket 145 and the second guide bracket 146, the movement of the first pressure plate 120 and the second pressure plate 130 can be guided and limited respectively, further improving the positioning accuracy and reliability of the pressing base plate 200. When the first pressure plate 120 moves, the first guide bracket 145 slides relative to the first pressure plate 120 along the first direction A, preventing the first pressure plate 120 from sliding in any direction other than the second direction B during movement. Similarly, when the second pressure plate 130 moves, the second guide bracket 146 slides relative to the second pressure plate 130 along the first direction A, preventing the second pressure plate 130 from sliding in any direction other than the second direction B during movement.

[0041] It should be noted that, in a preferred embodiment of this application, such as Figure 4 As shown, there are two first guide supports 145 and two second guide supports 146, and the two first guide supports 145 and the two second guide supports 146 are symmetrically distributed on opposite sides of the first fixed connecting rod 144.

[0042] Specifically, such as Figure 4 As shown, there are two first guide supports 145, which are distributed along a third direction C on opposite sides of the first fixed connecting rod 144, so as to be located on opposite sides of the drive rod 110. Similarly, there are two second guide supports 146, which are distributed along a third direction C on opposite sides of the first fixed connecting rod 144, so as to be located on opposite sides of the drive rod 110. Preferably, the end sidewalls of the first guide supports 145 can be closely fitted to the end sidewalls of the second guide supports 146 to improve the stability of the movement.

[0043] With this configuration, the two first guide brackets 145 can be slidably connected to both ends of the first pressure plate 120, and the two second guide brackets 146 can be slidably connected to both ends of the second pressure plate 130. This provides guidance and limiting to both sides of the first pressure plate 120 and the second pressure plate 130, effectively preventing deviation that may occur due to uneven force on one side of the guide and limiting, and further ensuring the smoothness of the pressure plate movement and the accuracy of the positioning.

[0044] Optionally, such as Figure 3 As shown, the first pressure plate 120 includes a first body 121 and two first sidewalls 122 that are respectively vertically arranged on opposite sides of the first body 121 along a third direction C; the linkage mechanism 140 also includes a second fixed link 147, which extends along a third direction C and is fixedly connected to the two first sidewalls 122 at both ends; one end of the first follower link 141 is hinged to the moving link 143 and the other end is hinged to the second fixed link 147.

[0045] Specifically, such as Figure 3 As shown, two first sidewalls 122 are vertically connected to opposite sides of the first body 121, forming a U-shaped structure for the first pressure plate 120. The two ends of the second positioning rod are fixedly connected to the two first sidewalls 122 to improve the connection stability of the substrate pressing device 100. One end of the first follower link 141 is hinged to the moving link 143, and the other end is hinged to the second fixed link 147, further improving the connection stability of the first follower link 141.

[0046] Optionally, such as Figure 3 As shown, the second pressure plate 130 includes a second body 131 and two second sidewalls 132 that are respectively vertically arranged on opposite sides of the second body 131 along a third direction C; the linkage mechanism 140 also includes a third fixed link 148, which extends along a third direction C and is fixedly connected to the two second sidewalls 132 at both ends; one end of the second follower link 142 is hinged to the moving link 143 and the other end is hinged to the third fixed link 148.

[0047] Specifically, such as Figure 3 As shown, the two second sidewalls 132 are respectively vertically connected to the opposite sides of the second body 131, forming a U-shaped structure for the second pressure plate 130. The two ends of the third positioning rod are fixedly connected to the two second sidewalls 132 to improve the connection stability of the substrate pressing device 100. One end of the second follower link 142 is hinged to the moving link 143, and the other end is hinged to the third fixed link 148, further improving the connection stability of the second follower link 142.

[0048] Optionally, such as Figure 4As shown, the first pressure plate 120 includes a first body 121 and two first sidewalls 122 respectively perpendicularly arranged on opposite sides of the first body 121 along a third direction C; the first sidewalls 122 are provided with first grooves 1221 along a first direction A; the linkage mechanism 140 also includes a first slide rail link 1491 extending along a third direction C, and the opposite ends of the first slide rail link 1491 are respectively inserted into the first grooves 1221 of the two first sidewalls 122; one end of the first guide bracket 145 is hinged to the first fixed link 144, and the other end is hinged to the first slide rail link 1491.

[0049] Specifically, such as Figure 4 As shown, a first groove 1221 is formed on the first sidewall 122 along the first direction A. The two ends of the first slide rail connecting rod 1491 are respectively inserted into the first grooves 1221 of the two first sidewalls 122 to further improve the connection stability of the substrate pressing device 100. One end of the first guide bracket 145 is hinged to the first fixed connecting rod 144, and the other end is hinged to the first slide rail connecting rod 1491. Therefore, when the first pressure plate 120 and the second pressure plate 130 move in directions that are opposite to or close to each other, the first guide bracket 145 can be driven to slide along the first direction A and connect with the first pressure plate 120. At this time, the first slide rail connecting rod 1491 connected to the first guide bracket 145 moves along the extension direction of the first groove 1221, thereby realizing the movement of the first guide bracket 145. This arrangement ensures the normal movement of the first guide bracket 145, while also preventing interference with the first body 121 due to its placement on the first sidewall 122, thus ensuring good surface contact between the first body 121 and the substrate 200.

[0050] Optionally, such as Figure 4 As shown, the second pressure plate 130 includes a second body 131 and two second sidewalls 132 respectively perpendicularly arranged on opposite sides of the second body 131 along a third direction C; the second sidewalls 132 are provided with second grooves 1321 along a first direction A; the linkage mechanism 140 also includes a second slide rail connecting rod 1492 extending along a third direction C, and the opposite ends of the second slide rail connecting rod 1492 are respectively inserted into the second grooves 1321 of the two second sidewalls 132; one end of the second guide bracket 146 is hinged to the first fixed connecting rod 144, and the other end is hinged to the second slide rail connecting rod 1492.

[0051] Specifically, such as Figure 4As shown, the second sidewall 132 has a second groove 1321 along the first direction A. The two ends of the second slide rail connecting rod 1492 pass through the two second grooves 1321 of the second sidewall 132 respectively, so as to further improve the connection stability of the substrate pressing device 100. One end of the second guide bracket 146 is hinged to the second fixed connecting rod 147, and the other end is hinged to the second slide rail connecting rod 1492. Therefore, when the first pressure plate 120 and the second pressure plate 130 move in directions that are opposite to or close to each other, the second guide bracket 146 can be driven to slide and connect with the second pressure plate 130 along the first direction A. At this time, the second slide rail connecting rod 1492 connected to the second guide bracket 146 moves along the extension direction of the second groove 1321, thereby realizing the movement of the second guide bracket 146. This arrangement ensures the normal movement of the second guide bracket 146, while also preventing interference with the second body 131 due to its placement on the second sidewall 132, thus ensuring good surface contact between the second body 131 and the substrate 200.

[0052] In one possible implementation of this application, such as Figure 3 As shown, the outer wall of the drive rod 110 is provided with an external thread 111, and the middle part of the moving connecting rod 143 has a mounting hole that passes through along the first direction A. The mounting hole is provided with an internal thread that matches the external thread 111. The drive rod 110 passes through the mounting hole and is screwed to the internal thread of the mounting hole through the external thread 111. A knob 112 is connected to the top of the moving connecting rod 143. The knob 112 drives the moving connecting rod 143 to rotate, so as to drive the moving connecting rod 143 to move along the first direction A.

[0053] Specifically, the bottom end of the drive rod 110 passes through the moving connecting rod 143, and the top end is provided with a knob 112; the drive rod 110 and the moving connecting rod 143 are threadedly connected by an external thread 111 and an internal thread. When the operator rotates the knob 112 clockwise, the drive rod 110 and the moving connecting rod 143 move relative to each other due to the screw connection, causing the moving connecting rod 143 to move upward. At this time, the first pressure plate 120 and the second pressure plate 130 move away from each other. When the operator rotates the knob 112 counterclockwise, the drive rod 110 and the moving connecting rod 143 move relative to each other due to the screw connection, causing the moving connecting rod 143 to move downward. At this time, the first pressure plate 120 and the second pressure plate 130 move closer to each other.

[0054] This configuration transforms the rotational motion of the drive rod 110 into the linear motion of the moving link 143 along the first direction A, improving drive efficiency and simplifying the drive process.

[0055] The substrate clamping device 100 provided in this application is used in the following way: In the initial state, the substrate pressing device 100 is in a tightened state, and the first pressing plate 120 and the second pressing plate 130 are close to each other; Place the first pressure plate 120 and / or the second pressure plate 130 of the substrate pressing device 100 at the relative positions of the substrate 200 to be pressed, rotate the knob 112, and through the linkage mechanism 140, move the first pressure plate 120 and the second pressure plate 130 along the second direction B to move away from each other until the substrate 200 is pressed tightly against the housing 300 to which the substrate 200 is to be bonded. After the substrate is pressed tightly, the subsequent curing operation can be carried out. At this time, the substrate pressing device 100 is in the unfolded state. After the curing operation is completed, rotate the knob 112 in the opposite direction. The linkage mechanism 140 causes the first pressure plate 120 and the second pressure plate 130 to move in the second direction B to move closer to each other. At this time, the substrate pressing device 100 is in a tightened state, and the substrate pressing device 100 can be taken out from the working position.
