[0031] Please refer to Figures 1 to 4 This embodiment discloses an auxiliary tooling for bonding a reinforcing plate, including a bracket 100, a movable push rod 200, and an elastic reset member 300. The bracket 100 is provided with an abutment surface 101, a mounting hole 102, and a first pressing and limiting part 103. The abutment surface 101 is located at the bottom of the bracket 100. Depending on the flexible circuit board to be processed, the abutment surface 101 can be a plane or it can be provided with a clearance space. The clearance space is used to avoid electronic components on the flexible circuit board. The abutment surface 101 has a positioning cavity 104 suitable for placing the reinforcing plate. It should be understood that the shape and size of the positioning cavity 104 are adapted to the shape and size of the reinforcing plate. Please refer to... Figure 3 and Figure 4 The bracket 100 has finger positions 105 on both sides of the mounting hole 102. The finger positions 105 are suitable for the user's fingers to place and apply force. The movable push rod 200 is movably inserted through the mounting hole 102 and can extend into the positioning cavity 104. The moving direction of the movable push rod 200 is perpendicular to the abutment surface 101. The movable push rod 200 is provided with a second pressing limit part 210, which can abut against the first pressing limit part 103. The elastic reset member 300 is installed on the bracket 100 and connected to the movable push rod 200. It is suitable for pressing and resetting the movable push rod 200. The elastic reset member 300 adopts an elastic structure such as a spring or tension spring.

[0032] The abutment surface 101 of the bracket 100 can abut against the flexible circuit board to be processed. The positioning cavity 104 opened in the abutment surface 101 can hold the reinforcing plate. The movable push rod 200 is movably inserted through the mounting hole 102 and can be pushed in a direction perpendicular to the abutment surface 101 to press the reinforcing plate and the flexible circuit board together. The bracket 100 and the movable push rod 200 are respectively provided with a first pressing limit part 103 and a second pressing limit part 210, which can limit the pushing stroke of the movable push rod 200 to avoid damage to the reinforcing plate and the flexible circuit board due to excessive pressure. After the movable push rod 200 is released, the movable push rod 200 is reset under the action of the elastic reset member 300. The bracket 100 is provided with a finger position 105 to facilitate the user to clamp and apply force. In this way, the bonding quality of the reinforcing plate can be improved and the workload can be reduced.

[0033] In some application examples, please refer to Figure 1 and Figure 3The support 100 includes a first support plate 110, a second support plate 120, and an intermediate connecting plate 130. The two ends of the intermediate connecting plate 130 are respectively connected to the first support plate 110 and the second support plate 120, and an movable space is provided between the first support plate 110 and the second support plate 120. As shown in the figure, the first support plate 110 and the second support plate 120 are distributed along the longitudinal direction, such as with the first support plate 110 located below the second support plate 120. The intermediate connecting plate 130 serves as a connecting structure, connecting and supporting the first support plate 110 and the second support plate 120. The intermediate connecting plate 130 can be a fully enclosed frame structure or an open connection structure. For example, the intermediate connecting plate 130 connects only to opposite sides of the first support plate 110 and the second support plate 120, such as the left and right sides or the front and back sides. The movable space provided between the first support plate 110 and the second support plate 120 can be used to accommodate other assembly structures, such as the elastic reset member 300, the first pressing limit part 103 and the second pressing limit part 210, and to provide a certain amount of movement space for the movable push rod 200. The side of the first support plate 110 that is away from the second support plate 120 serves as the abutment surface 101. For example, the first support plate 110 has opposing first and second surfaces, with the first surface facing the second support plate 120 and the second surface away from the second support plate 120, serving as the abutment surface 101 to facilitate contact with the circuit board to be processed. Mounting holes 102 and finger positions 105 are both provided on the second support plate 120. The mounting holes 102 allow the movable push rod 200 to pass through and guide the pushing action of the movable push rod 200. The finger positions 105 are provided on the second support plate 120 to facilitate application of force from above by the user.

[0034] In some application examples, please refer to Figure 3 and Figure 4 The first pressing limit part 103 is arranged along the edge of the positioning cavity 104 and protrudes towards the mounting hole 102, so that the shape of the first pressing limit part 103 is adapted to the shape of the positioning cavity 104. It limits the pushing stroke of the movable push rod 200 in different directions, ensuring that the movable push rod 200 is pushed into place and avoiding excessive pressure. The first pressing limit part 103 protrudes towards the mounting hole 102 and can be used as a guide structure. For example, when the movable push rod 200 partially enters the positioning cavity 104, the protruding part of the first pressing limit part 103 can push and guide the movable push rod 200 to ensure that the movement direction of the movable push rod 200 is correct.

[0035] In some application examples, please refer to [link / reference]. Figure 3 and Figure 4The first end of the movable push rod 200 is provided with a pressing head 220. The size of the pressing head 220 is adapted to the positioning cavity 104, which can apply pressure evenly to various positions of the reinforcing plate. This helps to improve the uniformity of pressing the reinforcing plate, thereby improving the adhesion between the reinforcing plate and the flexible circuit board and reducing air bubbles on the bonding surface. The second pressing limit part 210 is provided between the movable push rod 200 and the pressing head 220. The second pressing limit part 210 can stop the stroke of the pressing head 220 under the action of the first pressing limit part 103 after the pressing head 220 extends into the positioning cavity 104, so as to avoid damage to the reinforcing plate due to excessive pressure. In some application examples, a flexible pad is provided at the bottom of the press head 220. The flexible pad can be a flexible structure such as a silicone pad or a foam pad. The flexible pad is in flexible contact with the reinforcing plate to avoid scratching the surface of the reinforcing plate. Moreover, the flexible pad has a certain degree of elasticity. After the movable push rod 200 stops, the elastic structure of the flexible pad can apply a certain continuous pressure to the reinforcing plate to ensure that the reinforcing plate and the flexible circuit board are tightly bonded.

[0036] In some application examples, the movable push rod 200 is provided with a reset connection portion 230, which abuts against the elastic reset member 300. Exemplarily, the reset connection portion 230 can be a connection structure extending from the movable push rod 200, such as a pin mounted on the movable push rod 200; the reset connection portion 230 can also be a connection structure extending from the second pressing limit portion 210, for example, please refer to... Figure 3 and Figure 4 The structural member is connected to the second pressing limit part 210. In some application examples, there are multiple elastic reset members 300, which are arranged around the movable push rod 200. For example, there are two elastic reset members 300, which are distributed on opposite sides around the movable push rod 200; or, for example, there are four elastic reset members 300, which are distributed around the movable push rod 200. In this way, a reset force can be provided to different positions of the movable push rod 200.

[0037] In some application examples, please refer to Figure 3 and Figure 4 A sliding bearing 240 is connected between the movable push rod 200 and the bracket 100, and the sliding bearing 240 is installed in the mounting hole 102. The sliding bearing 240 can reduce the sliding resistance between the movable push rod 200 and the bracket 100, improve the smoothness of the sliding of the movable push rod 200, reduce the force applied to the movable push rod 200, and thus reduce the user's workload.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 the present utility model.
