Description

Technical Field

[0001] The present invention relates to the technical field of placement frames, and in particular to a PCB board placement frame. Background Art

[0002] In the electronics manufacturing industry, PCB boards, as important carriers of electronic components, require professional placement frames for carrying and transporting them during production and transportation. Currently, the common PCB board placement frames on the market mostly adopt a slot-type structure, which is designed to achieve orderly storage and positioning of PCB boards.

[0003] However, in actual operation, existing PCB placement frames face significant challenges, particularly during PCB transport, equipment handling, or production line vibrations. Due to factors such as bumpy driving in transport vehicles and vibrations from production line equipment, the frames are inevitably subject to vibrational impacts. This vibration can easily cause the PCB within the frame to shift, potentially causing it to break free. Once a PCB is broken free, it can not only cause physical damage such as scratches on the surface and component detachment, but can also cause electrical faults such as short circuits, severely impacting the quality and performance of the PCB. This can lead to decreased production efficiency, increased repair costs, and delayed customer orders, resulting in significant financial losses and reputational damage to the company. Summary of the Invention

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0028] Reference Figure 1-5 As shown, a PCB board placement frame includes a placement frame 1, and a plurality of fixed edge parts are fixed on both sides of the placement frame 1. The fixed edge parts are composed of two side plates 2 spaced apart;

[0029] By setting the fixed edge part, the PCB board is inserted into the placement frame 1 from top to bottom, so that the side part of the PCB board is inserted between the two side pieces 2. In this way, by utilizing the spaced layout of the connecting pieces in the fixed edge part and cooperating with multiple fixed edge parts, the PCB boards can be spaced and distributed to avoid contact and scratches between the boards; and the side positioning method can also be used to allow the connecting pieces to form a limit constraint on the PCB board from the side, thereby stabilizing the position of the PCB board in the frame.

[0030] Further, refer to Figure 1-3 As shown, it is worth noting that it also includes a pressing mechanism for enhancing the positioning strength of the PCB board on the placement frame 1;

[0031] The pressing mechanism includes a telescopic pressing part that rises and falls above the placement frame 1, a bearing seat 4 vertically fixed to one side of the placement frame 1, and a kinetic energy part provided on the bearing seat 4;

[0032] The kinetic energy part includes a bracket 5 mounted on a bearing seat 4 in an arch shape, a supply slide 6 fixed vertically to the inner wall of the top end of the bracket 5, and a movable sleeve 7 slidingly sleeved on the supply slide 6. A loading plate 8 is fixed to the wall of the movable sleeve 7, and the telescopic pressing part is detachably connected to the loading plate 8.

[0033] Through the arrangement of the kinetic energy part and the telescopic pressing part, the movable sleeve 7 in the kinetic energy part slides linearly down along the body of the supply slide 6, and the telescopic pressing part follows the movable sleeve 7 to press the PCB board downward, thereby supplementing the fixing force in the vertical direction after the PCB board is positioned by the side of the fixed edge part, and cooperating with the side limit of the fixed edge part to prevent the PCB board from falling out from the top of the frame due to vibration.

[0034] Further, refer to Figure 3 As shown, it is worth noting that the wall of the supply slide 6 is provided with a "7"-shaped limit track groove 9, and the movable sleeve 7 uses the limit track groove 9 as a motion trajectory to perform linear sliding, turning, etc. along the body of the supply slide 6;

[0035] The "7"-shaped track limiting groove 9 utilizes its unique trajectory to guide the movable sleeve 7 to first deflect and adjust its posture on the wall of the supply slide 6, and then move linearly downward along the slide body. When the PCB is placed into the placement frame 1, the movable sleeve 7 and the telescopic pressing part are guided by the lateral trajectory of the track limiting groove 9 to an avoidance position above the placement frame 1, providing sufficient space for smooth insertion of the PCB and avoiding collision and interference between the two.

[0036] After the PCB board is accurately positioned by the fixed edge part, the movable sleeve 7 is deflected along the turning trajectory of the limit track groove 9 through the external force driving structure, driving the telescopic pressing part to move accurately to the top of the placement frame 1, and then linearly move downward along the longitudinal trajectory of the limit track groove 9, so that the telescopic pressing part is attached to and pressed against the surface of the PCB board, forming an all-round clamping constraint on the top, bottom and sides with the fixed edge part, effectively resisting the impact of bumps and vibrations on the PCB board, greatly reducing the risk of it being shaken out of the placement frame 1, and significantly improving the stability and safety of the PCB board during storage and transportation.

[0037] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that a transmission screw 10 is vertically provided in the slide 6, and the shaft of the transmission screw 10 is threadedly connected to a driving screw sleeve 11, and a connecting block 12 is fixed between the driving screw sleeve 11 and the movable sleeve 7, and the connecting block 12 slides in the rail limit groove 9;

[0038] An operating rod 13 is rotatably provided in the inner wall of one side of the bracket 5, and the bottom end of the transmission screw 10 is rotated to pass through the supply slide 6 and is connected to one end of the operating rod 13 through a bevel gear transmission;

[0039] By rotating the operating rod 13 , the bevel gear can drive the transmission screw 10 , which drives the screw sleeve 11 to slide along the shaft of the transmission screw 10 or deflect along with the transmission screw 10 under the limiting action of the connecting block 12 .

[0040] Further, refer to Figure 3 and Figure 5 As shown, it is worth noting that the telescopic pressing portion includes a contraction seat 16 and a pressing seat 3 elastically sleeved on the bottom end of the contraction seat 16 by a spring, and a plurality of groups of top clamping members are provided on the bottom surface of the pressing seat 3. A linkage structure for the top clamping members to perform self-clamping action is provided in the pressing seat 3;

[0041] The top clamp is composed of two clips 14, one of which is fixed to the pressing seat 3, and a sliding pin 15 is fixed to the top of the other clip 14. The bottom end surface of the pressing seat 3 is provided with a sliding groove adapted to the sliding pin 15, and the sliding pin 15 slides in the sliding groove;

[0042] The linkage structure includes a linkage rod 18 fixed to the top of the sliding pin 15. The bottom end of the retracting seat 16 is provided with a wedge-shaped cavity 17 with a triangular longitudinal section. The end of the linkage rod 18 is spherical and penetrates into the wedge-shaped cavity 17 and abuts against the oblique inner wall of the wedge-shaped cavity 17.

[0043] By setting the top clamp and the linkage structure, when the kinetic energy part drives the telescopic pressing part downward to press the PCB board, the pressing seat 3 in the telescopic pressing part contacts the PCB board in advance, and the top of the PCB board is clamped between the two clamps 14 of the top clamp;

[0044] As the kinetic energy part continues to drive the telescopic pressing part downward, the contraction seat 16 penetrates into the pressing seat 3. At this time, the end of the linkage ball rod 18 slides obliquely along the inner wall of the wedge-shaped cavity 17. Due to the squeezing of the inclined surface of the wedge-shaped cavity 17, a horizontal component force is generated on the linkage ball rod 18. This component force acts on one of the clips 14 through the sliding pin 15, driving it close to the other clip 14.

[0045] In this way, the two clips 14 cooperate with each other to achieve a clamping effect on the top of the PCB board, firmly locking the PCB board in the frame to resist the risk of vibration and fall. Later, manual labor only needs to disassemble and separate the telescopic pressing part from the loading plate 8, and multiple clamped and fixed PCB boards can be transported and unloaded simultaneously at one time, improving operational efficiency and solving the tedious problem of traditional single-piece loading and unloading.

[0046] Further, refer to Figure 5 As shown, it is worth noting that a cross-shaped insert 19 is fixed to the top of the retracting seat 16, and the cross-shaped insert 19 is slidably inserted into the inner side of the loading plate 8;

[0047] By providing the cross-shaped inserting strip 19 , the shrinking seat 16 and the pressing seat 3 can be conveniently disassembled and separated from the loading plate 8 as a whole by simply plugging and unplugging.

[0048] Further, refer to Figure 5 As shown, it is worth noting that a locking rack 20 is fixedly embedded in the inner side wall of the pressing seat 3, and a buffer groove is opened on the side wall of the shrinking seat 16, in which a locking plug 21 slides elastically through a spring;

[0049] The teeth of the locking rack 20 are in the shape of a right-angled trapezoid, with the inclined surface of the teeth facing upward. One end of the locking plug 21 penetrates between two adjacent teeth of the locking rack 20, and the inserted end is in the shape of an inclined surface, which cooperates with the inclined surface of the teeth of the locking rack 20;

[0050] Through the arrangement of the locking rack 20 and the locking plug 21, when the kinetic energy part drives the retracting seat 16 downward to penetrate into the pressing seat 3, the inclined surface of the locking plug 21 contacts the inclined surface of the teeth of the locking rack 20 and slides relative to each other. Since the inclined surface of the teeth faces upward, during the downward movement of the retracting seat 16, the locking plug 21 is pressed by the inclined surface into the buffer groove to compress the spring until it passes over the current tooth and engages in the next tooth groove, forming a "step-by-step" locking;

[0051] Furthermore, when the retracting seat 16 descends to the target position, that is, the top clamp completes the clamping action on the PCB board, the locking plug-in 21 is locked into the tooth groove of the locking rack 20 under the action of the spring, and the right-angled trapezoidal structure of the teeth is used to prevent the retracting seat 16 from retreating upward under the elastic force, thereby locking the clamping state of the top clamp and ensuring that a stable clamping force is continuously provided in a bumpy environment.

[0052] Further, refer to Figure 5 As shown, it is worth noting that the cross-shaped inserting strip 19 is provided with a leading groove connected to the buffer groove, and a lifting rod 22 fixedly connected to the locking plug 21 slides in the leading groove;

[0053] By setting the lifting rod 22, the lifting rod 22 is moved to act on the locking plug 21 to retract into the buffer groove, causing the locking plug 21 to withdraw from between two adjacent teeth of the locking rack 20, thereby facilitating the release of the fixation of the retracting seat 16.
