Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing, and specifically relates to a circuit board clamping and fixing device. Background Technology

[0002] Circuit boards are one of the most important components in the electronics industry. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic devices, and military weapon systems, uses circuit boards to enable electrical interconnection between various electronic components such as integrated circuits.

[0003] During the production and processing of printed circuit boards (PCBs), it is necessary to inspect and repair prototypes and defective boards. For stability reasons, PCBs need to be clamped and secured during this process. Most existing clamping and securing devices apply vertical pressure to the PCBs, but they do not consider simultaneously positioning the PCBs during clamping to ensure automatic centering. However, careful attention to the center position is often required during repair; otherwise, misalignment can occur, reducing the accuracy and efficiency of the repair work. Therefore, an improved PCB clamping and securing device is proposed. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a circuit board clamping and fixing device with the advantage of self-adaptive centering.

[0005] To achieve the above objectives, this utility model provides a circuit board clamping and fixing device, including a support plate. A fence is installed on the upper surface of the support plate, and both ends are slotted with a sliding groove. A fastener is slidably disposed in each of the two sliding grooves. A connecting bolt is installed on each side of the two fasteners. A spring is installed between the two connecting bolts on the same side of the two fasteners. A rotating rod is rotatably disposed in the middle of the upper surface of the support plate. A turntable is installed at the top of the rotating rod. A connecting rod is installed on the side of the rotating rod. A handle is provided at the other end of the connecting rod.

[0006] The circuit board is placed between the two fasteners. The two fasteners are moved towards each other by the elastic pull of the spring, so that the circuit board is pressed on both sides at the same time and fixed in the center. The handle drives the connecting rod and the turntable to rotate by force. When the turntable rotates, it pushes the two fasteners towards both ends of the support plate and releases the circuit board.

[0007] As a further improvement of this utility model, a slider is installed at the bottom of the fastener, the slider is adapted to the slide groove, and the fastener slides horizontally in the slide groove by means of the slider.

[0008] As a further improvement of this utility model, both fasteners have slots on their opposite sides, which are for inserting circuit boards.

[0009] As a further improvement of this utility model, each end of the spring has a hook that hooks to the two connecting bolts on the same side of the two connecting bolts respectively, and the two fasteners are kept elastically connected by the two springs.

[0010] As a further improvement of this utility model, the turntable is composed of two convex discs. The two convex discs are semi-circular and staggered so that the turntable has two protruding parts that respectively fit against the opposite surfaces of the two fasteners.

[0011] As a further improvement of this utility model, the horizontal height of the upper surface of the turntable is lower than the lowest horizontal height of the slot, so that the circuit board can be smoothly inserted into the two slots.

[0012] As a further improvement of this utility model, the bottom of the side of the fence near the connecting rod has a notch, which provides space for the rotation of the connecting rod.

[0013] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0014] This utility model discloses a circuit board clamping and fixing device. A groove is created at both ends of a support plate, allowing two fasteners to slide horizontally. A spring and connecting bolt maintain the elastic connection between the two fasteners. After the circuit board is inserted into the groove, the spring pulls the two fasteners closer together, simultaneously clamping both sides of the circuit board and ultimately fixing it between the two fasteners. This achieves self-centering fixing of the circuit board, facilitating centered fixing during inspection and maintenance, improving accuracy and efficiency. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Example

[0022] Depend on Figure 1-4 A circuit board clamping and fixing device is provided, including a support plate 1. A fence 2 is installed on the upper end surface of the support plate 1 and both ends are slotted with a sliding groove 3. A fastener 4 is slidably arranged in each of the two sliding grooves 3. A connecting bolt 6 is installed on each side of the two fasteners 4. A spring 7 is installed between the two connecting bolts 6 on the same side of the two fasteners 4. A rotating rod 9 is rotatably arranged in the middle of the upper end surface of the support plate 1. A turntable 10 is installed at the top of the rotating rod 9. A connecting rod 11 is installed on the side of the rotating rod 9. A handle 12 is provided at the other end of the connecting rod 11.

[0023] The circuit board is placed between the two fasteners 4. The two fasteners 4 are moved towards each other by the elastic pull of the spring 7, so that the circuit board is pressed on both sides at the same time and fixed in the center. The handle 12 drives the connecting rod 11 and the turntable 10 to rotate by force. When the turntable 10 rotates, it pushes the two fasteners 4 towards both ends of the bearing plate 1 and releases the circuit board.

[0024] In this embodiment, the two fasteners 4 are allowed to slide horizontally through the grooves 3 formed by the slots at both ends of the bearing plate 1. The spring 7 and the connecting bolt 6 are used to maintain the elastic connection between the two fasteners 4. After the circuit board is inserted into the slot 5, the elasticity of the spring 7 pulls the two fasteners 4, causing them to move closer to each other. During the process of moving closer, the two sides of the circuit board are pressed synchronously, and finally the circuit board is fixed in the middle of the two fasteners 4, thereby achieving adaptive centering and fixing of the circuit board.

[0025] Specifically, refer to Figure 3-4 A slider 15 is installed at the bottom of the fastener 4. The slider 15 is adapted to the slide groove 3, and the fastener 4 slides horizontally in the slide groove 3 through the slider 15.

[0026] In this embodiment, by setting the slider 15 to be compatible with the slide groove 3, the fastener 4 can slide in the slide groove 3 through the slider 15, and the slider 15 and the slide groove 3 are used to limit the movement so that it can only slide horizontally in one direction, thus maintaining the stability of the sliding and fixing functions of the two fasteners 4.

[0027] Specifically, refer to Figure 1-3 Both fasteners 4 have slots on their opposite sides, each having a slot 5 for the circuit board to be inserted.

[0028] In this embodiment, a slot 5 is provided on the opposite side of the fastener 4 for the circuit board to be inserted, which limits and supports the circuit board, keeps the circuit board stable when it is pressed by the two fasteners 4, and prevents it from shaking.

[0029] Specifically, refer to Figure 1-4 Each end of the spring 7 has a hook 8 that hooks to the two connecting bolts 6 on the same side of the two connecting bolts 6 respectively. The two fasteners 4 are kept elastically connected by the two springs 7.

[0030] In this embodiment, hooks 8 are provided at both ends of the spring 7 to hook the two connecting bolts 6 respectively, thereby maintaining the elastic connection between the two fasteners 4 through the spring 7, and then pulling the two fasteners 4 in opposite directions through elasticity, thereby pressing and centering the circuit board on both sides.

[0031] Specifically, refer to Figure 1-4 The turntable 10 is composed of two convex discs 14. The two convex discs 14 are semi-circular and staggered so that the turntable 10 has two protruding parts that are respectively attached to the opposite surfaces of the two fasteners 4.

[0032] In this embodiment, the turntable 10 is composed of two protrusions 14, which are semi-circular and staggered. This allows the two symmetrical protrusions of the turntable 10 to fit against the opposing surfaces of the two fasteners 4. As a result, when the turntable 10 rotates, the two protrusions push the two fasteners 4 apart to release the circuit board.

[0033] Specifically, refer to Figure 1-4 The upper surface of the turntable 10 is at a lower level than the lowest level of the slot 5, so that the circuit board can be smoothly inserted into the two slots 5.

[0034] In this embodiment, by setting the horizontal height of the upper surface of the turntable 10 to be lower than the minimum horizontal height of the slot 5, the circuit board can be smoothly inserted into the two slots 5, avoiding collision and jamming between the circuit board and the upper surface of the turntable 10 during the insertion process.

[0035] Specifically, refer to Figure 1-3 The bottom of the side of the fence 2 near the connecting rod 11 has a notch 13, which provides space for the connecting rod 11 to rotate.

[0036] In this embodiment, a notch 13 is provided by slotting the bottom of the side of the fence 2 near the connecting rod 11, and the notch 13 provides room for the rotation of the connecting rod 11, so as to keep the rotation of the connecting rod 11 smooth and avoid collision and jamming during the rotation of the connecting rod 11, which would affect the realization of the rotation function of the turntable 10 and the release action of the two fasteners 4 on the circuit board.

[0037] Working principle:

[0038] In this utility model, the circuit board clamping and fixing device is used by an operator who applies force through the handle 12 to rotate the connecting rod 11 and the turntable 10. The rotation of the turntable 10 causes the two semi-circular convex discs 14 to rotate synchronously, squeezing the two fasteners 4 apart. The two fasteners 4 slide within the slide groove 3 via the slider 15 and move away from each other. Simultaneously, the connecting bolt 6 causes the spring 7 to extend and store energy. At this point, the circuit board is inserted into the gap between the two fasteners 4, and both ends of the circuit board are inserted into the two slots 5 of the two fasteners 4 respectively. Rotate the connecting rod 11 in the opposite direction to gradually release the pressure of the turntable 10 on the two fasteners 4. At this time, the spring 7 elastically returns to its original position and drives the two fasteners 4 to move closer to each other through the connecting bolt 6. As the two fasteners 4 move closer to each other, they simultaneously press the two sides of the circuit board, fixing the circuit board in the center of the two fasteners 4. This allows the device to achieve the self-adaptive centering and clamping function. When it is necessary to release the circuit board, rotate the connecting rod 11 again to make the turntable 10 push the two fasteners 4 apart and remove the circuit board from between the two fasteners 4.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
