[0002] In the field of electronics manufacturing, PCB (Printed Circuit Board) is a key component of electronic products. Its quality and performance directly affect the overall quality of electronic products. PCB character silkscreen printing is an important part of the PCB production process. Character silkscreen printing can not only mark the location and model of components, which facilitates subsequent assembly and maintenance, but also improve the overall recognizability and standardization of products.

[0003] Existing mounting brackets are typically fixed structures. When performing double-sided screen printing and curing of characters on PCBs of different sizes, they cannot be flexibly adjusted to adapt to different PCB sizes, requiring the bracket to be replaced. This limits their application in various production scenarios and fails to meet production needs. Therefore, a new PCB character double-sided screen printing and curing mounting bracket is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a PCB character double-sided screen printing curing fixture, including a support frame 1. An extension rod 4 is slidably connected to the inner wall of the support frame 1, and four sets are provided to expand the width of the two sets of support frames 1, thereby adapting to PCB boards of different specifications. The two sets of support frames 1 are used to support the PCB boards, enabling the PCB boards to be placed in a curing dryer for character screen printing curing. Slots 2 are provided on the outer side of the support frame 1, with multiple sets for placing multiple sets of PCB boards for character screen printing curing. A fixing rod 3 is fixedly connected to the outer side of the support frame 1 to increase the structural stability of the support frame 1. An adjustment mechanism is provided on the inner wall of the extension rod 4, including a control component and a limiting component. The control component includes a moving rod 51. By pressing two adjacent sets of moving rods 51, two sets of support members 52 can be moved in opposite directions, thereby releasing the squeezing limit on the clamping plate 53, realizing the release or locking of the limit on the support frame 1, thus adjusting the width between the support frames 1 to meet the fixing requirements of different PCB boards.

[0032] Reference Figure 2 - Figure 4 The movable rod 51 is slidably connected to the outside of the extension rod 4. Multiple sets of movable rods 51 are provided. A support member 52 is fixedly connected to the outside of the movable rod 51 to transmit the movement of the movable rod 51 and squeeze the clamping plate 53. The support member 52 is slidably connected to the inner wall of the extension rod 4. A clamping plate 53 is slidably connected to the inner wall of the extension rod 4. The outer side of the clamping plate 53 is convex and can be inserted into the slot 57 on the inner wall of the support frame 1 to limit the support frame 1 and keep the support frame 1 at a fixed distance. The inner wall of the support frame 1 has a slot 57 that can cooperate with the clamping plate 53 to limit the support frame 1. The outer side of the clamping plate 53 is inserted into the inner wall of the slot 57. Multiple sets of clamping plates 53 are provided. Adjacent sets of clamping plates 53 are elastically connected by a tension spring 54, which can provide elastic tension to the adjacent sets of clamping plates 53. When the support member 52 slides out, it can pull the clamping plate 53 into the inner wall of the extension rod 4.

[0033] Furthermore, the outer side of the support member 52 slides on the outer side of the card plate 53. The moving rod 51 and the extension rod 4 are elastically connected by a compression spring 56. One end of the compression spring 56 is fixedly connected to the outer side of the moving rod 51, and the other end of the compression spring 56 is fixedly connected to the inner wall of the extension rod 4. The compression spring 56 provides elastic force to the moving rod 51, so that the moving rod 51 can be stably inserted into the inner wall of the two sets of card plates 53 without being subjected to external force, thereby improving the stability of the device. The limiting component includes a stop bar 55, and multiple sets are provided to control the moving distance of the card plate 53. The stop bar 55 is fixedly connected to the outer side of the card plate 53, and the card plate 53 slides on the inner wall of the extension rod 4. A through groove is provided in the middle of the support member 52 so as not to block the tension spring 54. The outer side of the support member 52 and the outer side of the card plate 53 are set as inclined surfaces. The inclined surface support member 52 can squeeze the card plate 53 to both sides.

[0034] Reference Figure 1 and Figure 5 A snap-fit ​​assembly is provided on the outer side of the moving rod 51. The snap-fit ​​assembly includes a snap-fit ​​piece 62, which is rotatably connected to the inner wall of the right set of moving rods 51. The snap-fit ​​piece 62 and the moving rod 51 are elastically connected by a torsion spring 63. A fixing block 61 is fixedly connected to the front side of the left set of moving rods 51. When adjusting the width between the support frames 1, the snap-fit ​​piece 62 is snapped onto the outer side of the fixing block 61. The elastic force of the torsion spring 63 keeps the snap-fit ​​piece 62 in a snapped state, fixing the two adjacent sets of moving rods 51. This makes it convenient for the operator to accurately adjust the width between the support frames 1, improving the accuracy and stability of the adjustment. The left side of the snap-fit ​​piece 62 is set with an arc-shaped structure, which makes the snap-fit ​​process smoother and facilitates quick alignment with the fixing block 61 for snap-fit ​​operation.

[0035] Working principle: When using PCB boards of different specifications, the width between the support frames 1 needs to be adjusted. The operator presses the two adjacent sets of moving rods 51, and the moving rods 51 slide on the outside of the extension rod 4, which drives the support 52 fixed on its outside to slide on the inner wall of the extension rod 4, so that the support 52 slides out from the inner wall of the clamping plate 53. At this time, the tension spring 54 between the two adjacent sets of clamping plates 53 is released from the tension state, which drives the clamping plate 53 to slide out from the clamping groove 57 on the inner wall of the support frame 1, thereby releasing the limitation on the support frame 1.

[0036] In this way, the operator can pull and adjust the width between the two sets of support frames 1 to accommodate PCB boards of different specifications. After adjusting to the appropriate width, the moving rod 51 is released. The moving rod 51 returns to its original position under the elastic force of the compression spring 56, so that the support 52 re-cooperates with the clamping plate 53 to limit and fix the support frame 1.

[0037] During the adjustment of the width between the support frames 1, rotate the locking piece 62 on the inner wall of the right moving rod 51 so that it locks onto the outside of the fixing block 61 in front of the left moving rod 51. The locking piece 62 and the moving rod 51 are elastically connected by a torsion spring 63. The elastic force of the torsion spring 63 keeps the locking piece 62 in a locked state, thereby fixing the two adjacent sets of moving rods 51. This makes it convenient for the operator to accurately adjust the width between the support frames 1 and improves the accuracy and stability of the adjustment.

[0038] After adjusting the width of the support frame 1, place the PCB board through the slot 2, and then put the entire frame together with the PCB board into the curing dryer for character silkscreen curing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
