[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0022] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 4 The embodiment of the present application discloses a disassembly tool 100 for a circuit board assembly, wherein the circuit board assembly may include a bracket 200, a first circuit board 300 and a second circuit board 400. The first circuit board 300 and the second circuit board 400 may be PCBs (Printed Circuit Boards). The number of the first circuit board 300 or the second circuit board 400 may be one or more. By integrating different functional modules into the first circuit board 300 and the second circuit board 400, the integration of the circuit board assembly can be improved.

[0024] The first circuit board 300 and the second circuit board 400 are respectively arranged on the bracket 200. Specifically, the first circuit board 300 and the second circuit board 400 can be respectively arranged on both sides of the bracket 200 and fixed to the bracket 200 by screws, buckles, etc. Since the first circuit board 300 and the second circuit board 400 need to communicate with each other, they need to be interconnected with the help of connectors. The connector generally adopts a pluggable male and female design. When the male and female ports are in a plugged state, the first circuit board 300 and the second circuit board 400 cannot be separated under the restraint of the connector. When the male and female ports are in a separated state, the first circuit board 300 and the second circuit board 400 can be separated normally. The number of connectors is one or more, which causes the total plug-in and pull-out force of the connectors between the first circuit board 300 and the second circuit board 400 to reach 400-600N, which is much larger than the range that can be operated by hand. When the first circuit board 300 or the second circuit board 400 needs to be inspected and maintained respectively, there is a problem of greater difficulty in disassembly.

[0025] In view of the above problems, the embodiment of the present application discloses a disassembly tool 100, which may include a support member 110, a connector 120 and a driver 130. The support member 110 is used to connect with the bracket 200, and the connection between the support member 110 and the bracket 200 may be bolted, snap-fitted, etc. The support member 110 may be arranged on a side of the bracket 200 close to the first circuit board 300, and the support member 110 supports the driver 130 based on the bracket 200. The connector 120 is used to connect with the first circuit board 300, and the connection between the connector 120 and the first circuit board 300 may also be bolted, snap-fitted, etc. The driving member 130 is connected to the supporting member 110 and the connecting member 120 respectively. The driving member 130 can use the supporting member 110 as a fulcrum to drive the connecting member 120 to move toward the supporting member 110, thereby pulling the first circuit board 300 to overcome the plug-in and pull-out force of the connector between the first circuit board 300 and the second circuit board 400, so that the first circuit board 300 is separated from the second circuit board 400.

[0026] The specific connection method of the driving member 130 with the support member 110 and the connecting member 120 can be selected according to the specific type of the driving member 130. For example, the driving member 130 can be a cylinder, which includes a main body and a telescopic arm that can move telescopically relative to the main body. The main body can be fixed to the support member 110 by welding, bolt connection, etc., and the free end of the telescopic arm can be fixed to the connecting member 120 by welding, bolt connection, etc., and the telescopic movement of the telescopic arm is used to drive the connecting member 120 to move toward the support member 110, thereby driving the first circuit board 300 to move. Alternatively, the driving member 130 can also be a motor, which includes a housing and an output shaft. A thread can be set on the output shaft of the motor, and a threaded hole 121 can be set on the connecting member 120. The housing of the motor can be fixed to the support member 110, and the output shaft of the motor is inserted into the threaded hole 121 of the connecting member 120. The output shaft of the motor rotates, and the threaded fit is used to drive the connecting member 120 to move toward the support member 110, thereby driving the first circuit board 300 to move.

[0027] In the above two methods, the movement of the connecting member 120 and the first circuit board 300 is controlled automatically. In some optional embodiments of the present application, the driving member 130 can also be manually controlled. For example, the driving member 130 can be a lever, a threaded shaft 132 or other structures. As long as the supporting member 110 can be used as a fulcrum to drive the connecting member 120 to move toward the supporting member 110, and then drive the first circuit board 300 to move, so that the first circuit board 300 is separated from the second circuit board 400, the embodiments of the present application do not limit the specific type of the driving member 130.

[0028] From the above, it can be known that the disassembly tool 100 of the circuit board assembly disclosed in the embodiment of the present application improves the related technology, uses the bracket 200 of the circuit board assembly as a support, sets a support member 110 on the bracket 200, and connects it to the first circuit board 300 through the connecting member 120, and then connects the driving member 130 to the support member 110 and the connecting member 120 respectively, and the driving member 130 uses the support member 110 as a fulcrum to drive the connecting member 120 to move toward the support member 110, thereby pulling the first circuit board 300, so that the first circuit board 300 and the second circuit board 400 are separated from the plug-in and pull-out force. The above-mentioned disassembly tool 100 has the advantages of simple structure and convenient operation, which can reduce the difficulty of disassembling the circuit board; at the same time, it can also reduce the problem of circuit board damage caused by irregular disassembly process.

[0029] In some optional embodiments, such as Figures 1 to 4 As shown, the driving member 130 may include a bearing portion 131 and a threaded shaft 132. One end of the threaded shaft 132 is connected to the bearing portion 131. The threaded shaft 132 and the bearing portion 131 may be connected by welding. The threaded shaft 132 and the bearing portion 131 may also be an integrated structure to improve the structural strength. Along the radial direction of the threaded shaft 132, the size of the bearing portion 131 is slightly larger than the size of the threaded shaft 132.

[0030] The support member 110 is provided with a first through hole, and the threaded shaft 132 is passed through the first through hole. The outer diameter of the threaded shaft 132 is slightly smaller than the inner diameter of the first through hole, so that there is a certain gap between the first through hole and the threaded shaft 132, which can support the threaded shaft 132 to rotate in the first through hole. The bearing portion 131 is supported in the circumference of the first through hole, and the surface of the bearing portion 131 facing the threaded shaft 132 overlaps the support member 110, thereby supporting the threaded shaft 132.

[0031] Correspondingly, the connecting member 120 is provided with a threaded hole 121, and the threaded portion of the threaded shaft 132 extends into the threaded hole 121. By utilizing the threaded cooperation between the threaded shaft 132 and the threaded hole 121 and rotating the threaded shaft 132 to change the screwing length between the threaded shaft 132 and the threaded hole 121, the connecting member 120 can be driven to move toward the support member 110 along the axial direction of the threaded shaft 132, thereby pulling the first circuit board 300 to overcome the plug-in and pull-out force of the connector between the first circuit board 300 and the second circuit board 400, so that the first circuit board 300 is separated from the second circuit board 400.

[0032] By utilizing the cooperation between the threaded shaft 132 and the threaded hole 121, on the one hand, during the threaded screwing process, the applied force can be precisely controlled by controlling the number of rotations of the threaded shaft 132. For each rotation of the threaded shaft 132, the distance between the connector 120 and the support 110 will be shortened or expanded by 2 mm, and a uniform force will be generated at the corresponding parts. By continuously tightening or loosening the threaded shaft 132, the effect of uniform and stepped force application can be achieved, which can reduce the problem of damage to the circuit board and the connector. On the other hand, the operator can separate the first circuit board 300 from the second circuit board 400 by simply rotating the threaded shaft 132. The structure is simple and the operation is convenient, thereby reducing the difficulty of disassembling the circuit board.

[0033] Furthermore, if Figures 1 to 4 As shown, in order to facilitate the operator to control the driving member 130, a gripping portion 133 can also be provided on the driving member 130, so that the operator can hold the driving member 130. The gripping portion 133 is provided on the side of the bearing portion 131 facing away from the threaded shaft 132. The gripping portion 133 and the bearing portion 131 can be connected by welding, and the gripping portion 133 and the bearing portion 131 can also adopt an integrated structure. Along the radial direction of the threaded shaft 132, the size of the gripping portion 133 is larger than the size of the threaded shaft 132, so that a sufficient gripping area can be provided for the operator, reducing the relative sliding between the gripping portion 133 and the operator's hand, thereby improving the reliability of the operation. The shape of the gripping portion 133 can be rod-shaped, plate-shaped, etc. For example, the gripping portion 133 is rod-shaped, and the axial direction of the gripping portion 133 is perpendicular to the axial direction of the threaded shaft 132, forming a T-shaped driving member 130. The operator can control the driving member 130 by holding the upper part of the T.

[0034] In some optional embodiments, such as Figures 1 to 4 As shown, the support member 110 may include a first bottom plate 111, a first side plate 112 and a second side plate 113. The first side plate 112 and the second side plate 113 are arranged on the same side of the first bottom plate 111 and connected by the first bottom plate 111. The first side plate 112 and the second side plate 113 may have the same size. The first bottom plate 111 is supported by the bracket 200 and assembled with the bracket 200 by means of snap connection, bolt connection, etc. The first side plate 112 and the second side plate 113 are located on the side of the first bottom plate 111 facing away from the bracket 200. The first bottom plate 111, the first side plate 112 and the second side plate 113 may adopt an integrated structure, or may be made separately and then connected together by welding. The support member 110 adopts the above structure, which can improve its own structural strength and reduce deformation, thereby providing sufficient support effect for the driving member 130, thereby improving the stability of the disassembly tool 100.

[0035] The first through hole is opened in the first bottom plate 111, and the first bottom plate 111, the first side plate 112 and the second side plate 113 together form a receiving groove 114, and at least a part of the bearing part 131 is located in the receiving groove 114. The receiving groove 114 can limit the bearing part 131 and reduce the shaking of the bearing part 131, thereby improving the reliability of the cooperation between the threaded shaft 132 and the threaded hole 121.

[0036] Furthermore, if Figures 1 to 4 As shown, the support member 110 may also include a first fastener 115, which may be a screw, a clip, etc. The first base plate 111 is provided with a first mounting hole, and the first fastener 115 may extend into the first mounting hole. The support member 110 is connected to the bracket 200 through the cooperation between the first fastener 115 and the first mounting hole.

[0037] The number and location of the first mounting holes and the first fasteners 115 can be selected according to the size and shape of the first bottom plate 111. If space permits, as many first mounting holes and first fasteners 115 as possible can be provided to ensure that there are sufficient connection points between the first bottom plate 111 and the bracket 200, thereby improving the stability of the connection between the first bottom plate 111 and the bracket 200. For example, the first mounting holes and the first fasteners 115 can be provided at both ends of the first bottom plate 111, respectively.

[0038] Furthermore, if Figures 1 to 4 As shown, the connector 120 may include a second bottom plate 122, a third side plate 123, and a fourth side plate 124. The third side plate 123 and the fourth side plate 124 are disposed on the same side of the second bottom plate 122 and are connected through the second bottom plate 122. The third side plate 123 and the fourth side plate 124 may be disposed on a side of the second bottom plate 122 facing the first circuit board 300, and the third side plate 123 and the fourth side plate 124 are connected to the first circuit board 300, respectively.

[0039] The second bottom plate 122, the third side plate 123 and the fourth side plate 124 can be of an integrated structure or made separately and then connected together by welding. The connector 120 adopts the above structure to improve its structural strength and is not easily deformed when pulling the first circuit board 300. The threaded hole 121 is provided on the second bottom plate 122, and the threaded shaft 132 moves the connector 120 toward the support member 110 by cooperating with the threaded hole 121.

[0040] In some optional embodiments, such as Figures 1 to 4As shown, in order to improve the reliability of the connection between the third side plate 123 and the fourth side plate 124 and the first circuit board 300, a flange structure 125 can be provided on the edge of the third side plate 123 and the fourth side plate 124 facing away from the second bottom plate 122, and the flange structure 125 can be kept parallel to the second bottom plate 122. When connected with the first circuit board 300, the flange structure 125 can provide a sufficient contact surface.

[0041] The flange structure 125 can be assembled with the first circuit board 300 by means of clamping, bolt connection, etc. Specifically, the connector 120 may include a second fastener 126, which may be a screw, a buckle, etc. The flange structure 125 is provided with a second mounting hole 127, and the second fastener 126 may extend into the second mounting hole 127. The connector 120 is connected to the first circuit board 300 through the cooperation between the second fastener 126 and the second mounting hole 127. It should be noted that a hole position may be reserved on the first circuit board 300, and the reserved hole position is used to cooperate with the second fastener 126.

[0042] The number and location of the second mounting holes 127 and the second fasteners 126 can be selected according to the size and shape of the flange structure 125. For example, a plurality of second mounting holes 127 are spaced apart on the flange structure 125, and each second mounting hole 127 corresponds to a second fastener 126. When the first circuit board 300 is lifted, the plurality of second fasteners 126 can evenly distribute the force, thereby avoiding damage to the first circuit board 300 due to concentrated force.

[0043] In some optional embodiments, such as Figures 1 to 4 As shown, the flange structure 125 is provided with an avoidance space 128, and the avoidance space 128 is used to avoid components on the first circuit board 300 to avoid interference with the first circuit board 300. The shape of the avoidance space 128 can be an open groove or a hole, and the specific shape can be selected according to the structure of the first circuit board 300 and the avoidance requirements, and the embodiment of the present application does not limit this.

[0044] Furthermore, if Figure 4As shown, the threaded hole 121 is provided on the second bottom plate 122. The depth requirement of the threaded hole 121 cannot be met by relying solely on the second bottom plate 122. If the depth of the threaded hole 121 is too small, the matching length with the threaded shaft 132 will be short, and the threaded hole 121 and the threaded shaft 132 will easily slip. To address this problem, a nut 129 can be provided on the second bottom plate 122. The nut 129 is provided with an internal thread, and the threaded shaft 132 is provided with an external thread. According to the actual load-bearing requirements, a nut 129 of a corresponding length can be selected to ensure the matching length of the nut 129 and the threaded shaft 132. The nut 129 can be connected to the second bottom plate 122 by welding, and can be connected to the side of the second bottom plate 122 facing the bracket 200, or can be connected to the side of the second bottom plate 122 facing away from the bracket 200. The second bottom plate 122 is also provided with a second through hole. The second through hole and the nut 129 are relatively arranged to form the above-mentioned threaded hole 121 for the threaded shaft 132 to pass through.

[0045] In some optional embodiments, at least one of the first fastener 115 and the second fastener 126 is a captive screw. By utilizing the combination of the captive screw and the mounting hole, the connection can be achieved while preventing the fastener from loosening and slipping between the circuit boards, causing short circuits and damage to the circuit boards.

[0046] In some optional embodiments, such as Figure 1 , 2 As shown in FIG. 4 , the number of threaded holes 121 may be two or more, the number of driving members 130 is the same as the number of threaded holes 121, and at least two threaded holes 121 are spaced apart on the connecting member 120. Together with the driving member 130, the connecting member 120 and the first circuit board 300 can be pulled from different positions to evenly distribute the force, thereby ensuring the reliability and stability of the disassembly tool 100.

[0047] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. Considering the simplicity of the text, they will not be repeated here.

[0048] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
