[0029] Figure 1 is a schematic diagram of the structure of the clamp of this embodiment when fixing the substrate, referring to Figure 1 The clamp of this embodiment includes at least one carrier 10 and a crimping assembly 20, and the crimping assembly 20 is movably arranged above the carrier 10. The crimping assembly 20 includes a main body 21 and an abutting member 22 arranged on the bottom surface of the main body 21. The abutting member 22 is provided with an abutting arc 221. When fixing the substrate, the substrate is placed on the carrier 10, and the crimping assembly 20 moves downward until the abutting arc 221 abuts against the upper surface of the substrate and fixes the substrate on the carrier 10.
[0030] Reference Figure 1The fixture of this embodiment also includes a base 30. The carrier 10 is disposed on the base 30, and the size of the base 30 is larger than the size of the carrier 10. When placing a substrate, the carrier plate carrying the substrate moves to the top of the carrier plate 10 and positions the substrate and the carrier plate 10. After the substrate and the carrier plate 10 are positioned, the carrier plate moves downward. During the downward movement, the substrate falls on the raised carrier plate 10, and the carrier plate continues to descend until it falls on the base 30, so that the substrate and the carrier plate are separated to facilitate the fixing and processing of the substrate. Figure 1 The size of the carrier 10 is set to be smaller than that of the substrate so that the carrier will not collide with the carrier 10 when being separated from the substrate.
[0031] Figure 2 is a top view of the crimping assembly 20 of this embodiment, referring to Figure 2 The crimping assembly 20 includes a plurality of abutting members 22. The plurality of abutting members 22 are arranged in pairs on the bottom surface of the main body 21, and each group of abutting members 22 corresponds to a carrier 10 to form a fixed station. After the substrate is placed on the carrier 10, the crimping assembly 20 moves downward according to a preset downward pressure to crimp and fix the substrate.
[0032] Take a fixed workstation as an example, refer to Figure 1 , the carrier platform 10 is located between the two abutting members 22, and the two abutting members 22 are formed with a downwardly protruding abutting arc 221 at one end close to the carrier platform 10. When fixing the substrate, the crimping assembly 20 moves downward until the abutting arc 221 abuts against the top surface of the substrate and deforms. The two abutting members 22 are symmetrically located on both sides of the carrier platform 10, and the distance between the abutting members 22 and the carrier platform 10 is also the same. When pressing the substrate, the substrate can be kept stable, which helps to press the substrate stably on the carrier platform 10. Among them, taking the time when the abutting arc 221 just contacts the substrate as the starting point, the distance that the crimping assembly 20 continues to move downward is the downward pressure. Before fixing the substrate, the downward pressure is pre-set according to the substrate to ensure that the abutting member 22 can fully press the substrate to fix the substrate, while also avoiding damage to the substrate caused by excessive pressure.
[0033] Optionally, one or more groups of abutment members 22 may be provided on one fixed workstation, or three or more abutment members 22 may form a group.
[0034] Figure 3 is a schematic diagram of the overall structure of the abutment member 22 of this embodiment, referring to Figure 3, the abutment member 22 also includes a connecting portion 222. The connecting portion 222 is arranged in parallel and spaced below the main body 21, one end of the connecting portion 222 is connected to the main body 21, and the other end of the connecting portion 222 is connected to the abutting arc 221. In the process of the abutment member 22 moving downward to press the substrate, the connecting portion 222 gradually bends and deforms, thereby generating a certain elastic force, providing a certain pressure for the abutting arc 221 to press the substrate. The connecting portion 222 is spaced from the main body 21, providing a deformation space for the end of the connecting portion 222 connected to the abutting arc 221. In addition, the connecting portion 222 is arranged parallel to the main body 21, so that the force direction of the end of the connecting portion 222 connected to the abutting arc 221 is vertically upward, ensuring stable contact between the abutting arc 221 and the substrate, and preventing the abutting arc 221 from displacement and sliding.
[0035] Reference Figure 3 The connecting portion 222 is configured as a T-shaped structure, the abutting arc 221 is configured at the bottom end of the connecting portion 222 , and the top end of the connecting portion 222 is connected and fixed to the main body 21 .
[0036] Reference Figure 1 , a fastener 23 is provided at the top of the connecting portion 222. A connecting hole 223 is provided at one end of the abutting member 22 away from the abutting arc 221, and the fastener 23 passes through the connecting hole 223 to connect with the main body 21. The connecting holes 223 are provided on both sides of the top of the T-shaped structure to ensure that the abutting member 22 can be stably connected to the main body 21. The abutting member 22 is detachably connected to the main body 21 through the fastener 23, which facilitates timely disassembly and replacement of damaged parts, thereby improving the efficiency of maintenance and assembly. In addition, the portion of the connecting portion 222 close to the abutting arc 221 is the bottom end of the T-shaped structure, which is relatively slender and easier to deform to facilitate pressing and fixing the substrate.
[0037] Optionally, the connecting portion 222 may also be configured as other structures, such as a square structure, etc., and the abutting member 22 and the main body 21 may also be fixedly connected by welding or the like.
[0038] Reference Figure 1 The bottom surface of the main body 21 is provided with a boss 212, one end of the connecting portion 222 is connected to the boss 212, and there is a gap between the other end and the bottom surface of the main body 21. The connecting portion 222 is fixed to the main body 21 through the boss 212, which can effectively reduce the contact area between the connecting portion 222 and the main body 21, so that the connecting portion 222 is more likely to deform to generate elastic force when the abutting member 22 fixes the substrate. At the same time, the setting of the boss 212 allows a gap to be provided between the connecting portion 222 and the bottom surface of the main body 21, which is used to provide deformation space for the connecting portion 222.
[0039] Further, refer to Figure 3A weight-reducing hole 224 is also provided on the connecting portion 222 , which can effectively improve the stress distribution and enhance the durability and reliability of the abutting member 22 .
[0040] Reference Figure 3 The abutting arc 221 extends downward from the connecting portion 222 and then bends upward to form a hook shape. During the downward movement of the crimping assembly 20, the downwardly protruding abutting arc 221 first contacts the substrate in the form of a point, and then increases the contact area with the substrate during the gradual downward movement. The increase in the contact area makes the pressure distribution on the substrate more uniform, preventing the substrate from being locally deformed or damaged when subjected to force. At the same time, the arc-shaped design enables the abutting arc 221 to effectively disperse stress during the process of pressing the substrate, avoiding the phenomenon of stress concentration on the substrate.
[0041] In this embodiment, the abutment 22 is configured as a beryllium bronze abutment, which has a high fatigue limit and good wear resistance, and helps to extend the service life of the abutment 22. In addition, the thickness of the abutment 22 is set to 0.3 mm, which prevents the abutment 22 from being deformed due to long-term bending deformation, and helps to increase the bending stress of the abutment 22 when it is bent, and enhances the stability when fixing the substrate.
[0042] Reference Figure 2 The main body 21 is provided with at least one hollow portion 211. The hollow portions 211 correspond to the positions of the support platform 10 and are the same in number. A group of abutment members 22 are symmetrically provided on the outer side of each hollow portion 211.
[0043] Take a fixed workstation as an example, refer to Figure 1 The size of the hollow portion 211 is larger than that of the substrate. When the substrate is fixed, the hollow portion 211 is located directly above the substrate, and the processing equipment can extend from the hollow portion 211 into the fixed station to perform processing such as welding and dispensing on the substrate.
[0044] The clamp for fixing the substrate provided in the embodiment of the present application is provided with abutment members on both sides of the support platform, and the substrate is pressed and fixed by moving the abutment members downward, and a hollow portion is also provided to facilitate processing of the substrate. Among them, the abutment members are provided with abutment arcs to ensure full contact with the substrate, effectively improving the stability of the substrate when it is fixed, and at the same time, it can also reduce stress concentration on the substrate, reduce damage to the substrate, and improve product quality.
[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
