Detailed implementation manners

[0028] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail the specific embodiments of the "a sliding locking structure and a PCB clamping frame" of the present utility model with reference to the accompanying drawings.

[0029] See Figures 1-3 , in this embodiment, the sliding locking structure includes a sliding base 100, a sliding member 200 and a locking member 300; a first chute 101 and a first locking portion 102 are provided on the sliding base 100, and the first locking portion 102 is arranged along the first chute 101; the sliding member 200 includes a sliding portion 201, one end of the sliding portion 201 is provided with a first slider 202, the first slider 202 is slidably arranged in the first chute 101, and the sliding member 200 moves relative to the sliding base 100 along the first chute 101 through the first slider 202; the locking member 300 is slidably arranged on the sliding portion 201, and a second locking portion 301 and an unlocking inclined surface 302 are provided on the locking member 300; a first elastic member 303 is arranged between the locking member 300 and the sliding member 200, the first elastic member 303 is preferably a spring, and the first elastic member 303 has a tendency to drive the second locking portion 301 to move closer to and press against the first locking portion 102, so as to press the first locking portion 102 and the second locking portion 301 tightly, so that the two are coordinated and locked to limit the sliding of the sliding member 200 on the sliding base 100; when the unlocking inclined surface 302 is stressed, it drives the second locking portion 301 to move away from the first locking portion 102 to release the restriction on the sliding portion 201 and facilitate sliding.

[0030] It should be noted that, in this embodiment, the first locking portion 102 and the second locking portion 301 are preferably tooth patterns, so that they can be locked even if there is a slight misalignment between them to prevent sliding; the unlocking method of this sliding locking structure adopts the unlocking inclined surface 302. In automated production, even if the direction of the force applied to the unlocking inclined surface 302 is deviated, the unlocking inclined surface 302 can still convert this force into the driving force for unlocking. Through a simple inclined surface design, while the sliding locking structure is simple in design, it is more suitable for automated production.

[0031] Further see Figure 2 and Figure 3, in this embodiment, a first roller 203 is provided on the first sliding head 202. The first roller 203 rolls in the first chute 101. By means of the roller, the sliding friction is converted into rolling friction, reducing the frictional force and increasing the sensitivity of sliding.

[0032] More specifically, in this embodiment, the axes of the first sliding head 202, the locking member 300, and the first chute 101 are all located in the same vertical plane, and the axes of the locking member 300 and the sliding member 200 are located on the same straight line. In this way, during the locking and unlocking processes, the center of force is not easily offset, the locking position will not shift, and the locking and unlocking processes are more stable.

[0033] Further refer to Figures 4-6 , a PCB clamping frame is provided. In this embodiment, the clamping frame includes a fixed frame bar 400. Two side frame bars 401 are perpendicularly and fixedly connected to both ends of the fixed frame bar 400. One ends of the two side frame bars 401 are connected to each other through a connecting frame bar 402 to form a closed frame structure. A moving frame bar 403 parallel to the fixed frame bar 400 is arranged between the side frame bars 401. The moving frame bar 403 and the side frame bars 401 are slidably connected through the above-mentioned sliding locking structure. Sliding bases 100 are fixedly connected to the side frame bars 401, and sliding members 200 are fixedly connected to both ends of the moving frame bar 403; plate clamping assemblies 404 are arranged on both the moving frame bar 403 and the fixed frame bar 400. A clamping area 405 is formed between the moving frame bar 403 and the fixed frame bar 400. The moving frame bar 403 can move relative to the fixed frame bar 400 to adjust the size of the clamping area 405 for clamping and fixing PCB boards of different sizes.

[0034] It should be noted that the above-mentioned PCB clamping frame is used in the automated production process of PCBs. In the normal state of being not stressed, the moving frame bar 403 and the side frame bars 401 are restricted by the sliding locking structure and remain relatively fixed, and the plate clamping assemblies 404 remain in the clamped state.

[0035] Further refer to Figure 4 and Figure 5 , in this embodiment, the clamping frame further includes a partition frame bar 406. One end of the partition frame bar 406 is fixedly connected to the fixed frame bar 400, and the other end is fixedly connected to the connecting frame bar 402, and the partition frame bar 406 is parallel to the side frame bars 401; the moving frame bar 403 and the partition frame bar 406 are slidably and cooperatively connected; the partition frame bar 406 divides the clamping area 405 into two parts, so that two PCB boards can be clamped and fixed on one clamping frame. Of course, in other embodiments, multiple partition frame bars 406 can be provided to divide multiple clamping areas 405, which are designed according to actual needs and are not fixed to one partition frame bar 406.

[0036] More specifically, in this embodiment, a second chute 4061 parallel to the side frame bar 401 is provided on the partition frame bar 406, and a second slider 4031 is provided on the moving frame bar 403. The second slider 4031 slides along the second chute 4061. In this way, the second chute 4061 has a limiting effect on the second slider 4031, which can increase the sliding stability of the moving frame bar 403 and prevent it from shifting during the sliding process. At the same time, a second roller 4032 can also be provided on the second slider 4031, and the second roller 4032 rolls in the second chute 4061, further reducing the friction force received when the moving frame bar 403 slides and increasing the sliding sensitivity.

[0037] More specifically, in this embodiment, baffle members 407 are provided on the moving frame bar 403, the fixed frame bar 400, and the side frame bar 401. The baffle members 407 are all located within the clamping plate area 405, and the front end faces of the baffle members 407 are all located on the same horizontal plane for carrying the PCB board.

[0038] Further referring to Figure 6 , in this embodiment, the plate clamp assembly 404 includes a clamp body 4041 and a clamp head 4043. The clamp head 4043 is fixedly connected to one end of the clamp body 4041. The clamp body 4041 is hinged to the moving frame bar 403 / fixed frame bar 400, and a second elastic member 4044 is provided between the clamp body 4041 and the moving frame bar 403 / fixed frame bar 400. The second elastic member 4044 has a tendency to drive the clamp head 4043 to abut and press against the baffle member 407 to clamp the PCB board. An opening clamp inclined surface 4042 is provided on the clamp body 4041. When the opening clamp inclined surface 4042 is subjected to force, it drives the clamp head 4043 to move away from the baffle member 407 to open the clamp head 4043. Even if the direction of the force received during automated production is deviated, the opening clamp inclined surface 4042 can still convert the forces in different directions into opening clamp forces to open the clamp head 4043, with a large allowable error, making it more suitable for automated production.
