Description

Technical Field

[0001] This utility model relates to the field of circuit board clamping technology, and more specifically, to a circuit board transfer and positioning clamp. Background Technology

[0002] Solder, as a key industrial material for connecting electronic components in electronic circuits, plays an indispensable role in the electronics industry, home appliance manufacturing, automobile production, repair services, and even daily life. However, traditional soldering methods rely on manual soldering, which is not only inefficient but also difficult to guarantee consistent soldering quality. Therefore, a circuit board transfer and positioning fixture described in the document with publication number CN217859231U can effectively solve the aforementioned problems.

[0003] However, when fixing the circuit board in this device, multiple positioning heads need to be rotated sequentially to apply pressure to the circuit board for fixation. Rotating multiple positioning heads one by one increases the number of steps and complexity of the operation. For operators, it requires more time and effort to complete the fixing of the circuit board, which reduces the installation efficiency of the circuit board. Therefore, we propose a circuit board transfer positioning fixture. Utility Model Content

[0004] Based on the aforementioned technical problem that the device requires rotating multiple positioning heads sequentially to apply pressure to the circuit board during fixing, the increased steps and complexity of the operation, requiring operators to spend more time and effort to complete the fixing work and reducing the installation efficiency of the circuit board, this utility model proposes a circuit board transfer positioning fixture.

[0005] This utility model proposes a circuit board transfer and positioning fixture, comprising an outer frame, a first inner frame fixedly connected to the inner wall of the outer frame, mounting grooves formed on the outer walls of both the first and second inner frames, sliding grooves formed on both sides of the inner wall of the outer frame, a second inner frame fitted onto the inner wall of the outer frame, two sliding plates fixedly connected to the outer walls of the second inner frame, the ends of the two sliding plates being slidably connected to the inner walls of the sliding grooves, multiple connecting rods slidably connected to the tops of both the first and second inner frames, the ends of the connecting rods penetrating through the first inner frame and extending into it, a first limiting sleeve fixedly connected to the outer circumference of each connecting rod, a first spring fitted onto the outer circumference of each connecting rod, a connecting seat fixedly connected to the bottom of each connecting rod, a first rotating shaft rotatably connected to the inner wall of each connecting seat, both ends of the first rotating shaft penetrating through the connecting seat and extending to its outer side, a torsion spring fitted onto both ends of the first rotating shaft, a second limiting sleeve fixedly connected to both ends of the first rotating shaft, and a pressure roller fixedly connected to the outer circumference of the first rotating shaft.

[0006] Preferably, one end of the first spring is fixedly connected to the first limiting sleeve, and the other end of the first spring is fixedly connected to the corresponding first inner frame and second inner frame respectively.

[0007] Preferably, one end of the torsion spring is fixedly connected to the second limiting sleeve, and the other end of the torsion spring is fixedly connected to the connecting seat.

[0008] Preferably, the outer circumferential wall of the pressure roller has a flat surface, and a rubber sleeve is fixedly connected to the outer circumferential wall of the pressure roller.

[0009] Preferably, connecting sleeves are fixedly connected to both sides of the first inner frame, and through holes are opened on the outer wall of the connecting sleeves. Two side frames are fixedly connected to the outer wall of the connecting sleeves. A fixing rod is fixedly connected to the inner wall of each of the two side frames. A slider is slidably connected to the outer circumference of each fixing rod. A second spring is sleeved on the outer circumference of each fixing rod. A locking plate is fixedly connected between the two sliders. A cross rod is fixedly connected to the top of the locking plate.

[0010] Preferably, one end of the second spring is fixedly connected to the slider, and the other end of the second spring is fixedly connected to the inner wall of the side frame.

[0011] Preferably, a plurality of support plates are fixedly connected to the top of the first inner frame, and a second rotating shaft is fixedly connected between each two adjacent support plates. A rocker arm is rotatably connected to the outer circumference of each of the two second rotating shafts, and a connecting hole is provided on the outer wall of each of the two rocker arms. The end of the cross rod passes through the connecting hole and extends to its outer side.

[0012] Preferably, slide rods are fixedly connected to both sides of the second inner frame, the ends of the slide rods are slidably connected to the inner wall of the connecting sleeve, and toothed plates are fixedly connected to the outer walls of the slide rods, with the toothed plates engaging with the locking plates.

[0013] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0014] 1. When the circuit board is inserted into the inner frame at an angle, it will squeeze the pressure roller and stretch the first spring. As the pressure roller rotates, its plane contacts the top of the circuit board and the circuit board is quickly fixed under the elastic force of the first spring. This design simplifies the circuit board installation process, improves installation efficiency, and ensures the stability of the circuit board during installation.

[0015] 2. By simultaneously pressing the two pry bars to pry the cross bar, the locking plate moves and releases the engagement with the toothed plate. This design allows the position of the second inner frame to be flexibly adjusted. This mechanism allows users to adjust the distance between the first and second inner frames according to the size of the circuit board, thereby adapting to the installation of circuit boards of different sizes. This flexibility improves the versatility and practicality of the equipment. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a circuit board transfer and positioning fixture includes an outer frame 1, a first inner frame 2 fixedly connected to the inner wall of the outer frame 1, mounting grooves 4 on the outer walls of both the first inner frame 2 and the second inner frame 3, sliding grooves 6 on both sides of the inner wall of the outer frame 1, a second inner frame 3 fitted onto the inner wall of the outer frame 1, two sliding plates 5 fixedly connected to the outer wall of the second inner frame 3, the ends of the two sliding plates 5 being slidably connected to the inner wall of the sliding grooves 6 respectively, multiple connecting rods 7 slidably connected to the top of both the first inner frame 2 and the second inner frame 3, the ends of the connecting rods 7 penetrating through the first inner frame 2 and extending into it, a first limiting sleeve 8 fixedly connected to the outer circumference of each connecting rod 7, a first spring 9 fitted onto the outer circumference of each connecting rod 7, a connecting seat 10 fixedly connected to the bottom of each connecting rod 7, and a first rotating spring 9 rotatably connected to the inner wall of each connecting seat 10. The first rotating shaft 11 has two ends that pass through the connecting seat 10 and extend to its outer side. Both ends of the first rotating shaft 11 are fitted with torsion springs 13, and both ends are fixedly connected to second limiting sleeves 12. A pressure roller 14 is fixedly connected to the outer circumference of the first rotating shaft 11. One end of the first spring 9 is fixedly connected to the first limiting sleeve 8, and the other end of the first spring 9 is fixedly connected to the corresponding first inner frame 2 and second inner frame 3. One end of the torsion spring 13 is fixedly connected to the second limiting sleeve 12, and the other end of the torsion spring 13 is fixedly connected to the connecting seat 10. The design of the first spring 9 and the pressure roller 14 not only provides a mechanism for fixing the circuit board but also acts as a buffer. When the circuit board is subjected to external impact or vibration, the spring can absorb some energy, thereby reducing damage to the circuit board. This design helps extend the service life of the circuit board and maintain its functional integrity.

[0026] like Figure 4 As shown, the outer circumference of the pressure roller 14 has a flat surface, and a rubber sleeve 15 is fixedly connected to the outer circumference of the pressure roller 14.

[0027] like Figure 5 As shown, connecting sleeves 22 are fixedly connected to both sides of the first inner frame 2. The outer wall of the connecting sleeve 22 has a through hole 23. Two side frames 24 are fixedly connected to the outer wall of the connecting sleeve 22. The inner wall of the two side frames 24 is fixedly connected to a fixing rod 26. The outer circumference of the fixing rod 26 is slidably connected to a slider 25. The outer circumference of the fixing rod 26 is fitted with a second spring 27. A retaining plate 28 is fixedly connected between the two sliders 25. A cross rod 29 is fixedly connected to the top of the retaining plate 28. One end of the second spring 27 is fixedly connected to the slider 25, and the other end of the second spring 27 is fixedly connected to the inner wall of the side frame 24.

[0028] like Figure 6 As shown, a number of support plates 18 are fixedly connected to the top of the first inner frame 2. A second rotating shaft 19 is fixedly connected between two adjacent support plates 18. A rocker plate 20 is rotatably connected to the outer circumference of the two second rotating shafts 19. A connecting hole 21 is opened on the outer wall of the two rocker plates 20. The end of the cross rod 29 passes through the connecting hole 21 and extends to its outer side.

[0029] like Figure 2 and Figure 6 As shown, slide rods 16 are fixedly connected to both sides of the second inner frame 3. The ends of the slide rods 16 are slidably connected to the inner wall of the connecting sleeve 22. Toothed plates 17 are fixedly connected to the outer walls of the slide rods 16. The toothed plates 17 are engaged with the locking plates 28. By pressing the two pry bars 20 simultaneously, the cross rod 29 is pried, which in turn moves the locking plates 28 and releases the engagement with the toothed plates 17. This design allows the position of the second inner frame 3 to be flexibly adjusted. This mechanism allows users to adjust the distance between the first inner frame 2 and the second inner frame 3 according to the size of the circuit board, thereby adapting to the installation of circuit boards of different sizes. This flexibility improves the versatility and practicality of the equipment.

[0030] Working principle: Pressing both rocker arms 20 simultaneously moves the cross bar 29 upwards, which in turn moves the locking plate 28. The locking plate 28 then moves the slider 25 along the fixed rod 26, compressing the second spring 27 and disengaging the locking plate 28 from the toothed plate 17. This pushes the second inner frame 3, causing the slide plate 5 to slide along the inner wall of the slide groove 6. The second inner frame 3 then moves the slide rod 16 and the toothed plate 17 along the inner wall of the connecting sleeve 22. After releasing the rocker arms 20, the locking plate 28 engages with the toothed plate 17 under the elastic force of the second spring 27, thus fixing the position of the second inner frame 3. By adjusting the distance between the first inner frame 2 and the second inner frame 3, circuit boards of different sizes can be installed.

[0031] Tilt the circuit board so that its two sides are inserted into the first inner frame 2 and the second inner frame 3 respectively. At this time, the circuit board squeezes the pressure roller 14, and the connecting rod 7 slides upward along the first inner frame 2 and the second inner frame 3 respectively, so that the first spring 9 is stretched. At the same time, the pressure roller 14 drives the first rotating shaft 11 to rotate, so that the plane on the pressure roller 14 contacts the top of the circuit board. Under the elastic force of the first spring 9, the circuit board can be quickly fixed in the first inner frame 2 and the second inner frame 3.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
