Description

Technical Field

[0001] This utility model relates to the field of PCB assembly technology, and specifically to a clamping device for PCB assembly. Background Technology

[0002] In the assembly process of PCB (printed circuit board), stable and precise clamping of the PCB is a key step to ensure assembly quality and efficiency. However, some mechanical fixtures require multiple screws or nuts to tighten for clamping, which takes a long time to install and remove, is inconvenient to operate, and seriously affects production efficiency. Moreover, some fixtures lack precise positioning mechanisms, which makes it easy for the PCB to deviate in position during the clamping process. Utility Model Content

[0003] The purpose of this invention is to provide a PCB assembly clamping device that is simple to operate, can achieve precise positioning and stable clamping of PCBs, and is highly flexible in use.

[0004] A PCB assembly clamping device includes a support base plate and a placement plate, a quick clamp, a movable plate, and clamping blocks mounted on the support base plate. The placement plate and / or the movable plate are provided with a plurality of limiting blocks. A plurality of clamping blocks are mounted on one side of the movable plate or the placement plate. The clamping blocks cooperate with the limiting blocks on the movable plate and / or the placement plate to clamp and limit the PCB. The end of the movable plate away from the clamping blocks is connected to the push rod of the quick clamp.

[0005] In the above scheme, pressing down the quick clamp causes the quick clamp's push rod to move the movable plate towards the placement plate, making the movable plate abut against the placement plate. This allows the clamping block, in conjunction with the limiting blocks on the movable block and / or the placement block, to limit and clamp the PCB. The operation is simple, enabling rapid PCB clamping. The cooperation between the clamping block and the limiting block ensures reliable PCB clamping, preventing PCB shaking or displacement during assembly. This stable clamping effect helps improve assembly accuracy and quality, ensuring accurate installation of electronic components on the PCB, thereby improving product performance and reliability. PCBs can be placed alone on the movable plate, alone on the placement plate, or simultaneously on both the movable and placement plates, increasing the flexibility of the device. Different PCB specifications can be assembled simultaneously on the movable and placement plates, improving production efficiency.

[0006] Furthermore, the clamping block includes a first horizontal plate, a second horizontal plate, and a vertical plate. The vertical plate is vertically disposed between the first horizontal plate and the second horizontal plate. The clamping block is configured as an axisymmetric structure with the vertical plate as the axis of symmetry. The clamping block has clamping grooves for clamping the PCB formed on both sides of the vertical plate.

[0007] In the above scheme, the clamping block is configured as an axisymmetric structure with the vertical plate as the axis of symmetry. The clamping plate has clamping grooves on both sides of the vertical plate. This eliminates the need to consider the problem of reverse installation when it is installed on the placement plate or the movable plate, which can improve the installation efficiency. Moreover, the clamping grooves on both sides of the clamping plate can clamp the PCB on the placement plate or the PCB on the movable plate, or clamp the PCB on both the placement plate and the movable plate at the same time, which increases the flexibility of the device and can meet different production needs.

[0008] Furthermore, the first horizontal plate is provided with a first through hole, the second horizontal plate is provided with a second through hole corresponding to the first through hole, and the position of the movable plate or placement plate for mounting the clamping block is provided with a mounting groove, and the mounting groove is provided with a connecting hole corresponding to the first through hole and the second through hole.

[0009] In the above scheme, the first through hole on the first horizontal plate and the second through hole on the second horizontal plate correspond to the connecting holes on the mounting slot of the movable plate or the placement plate, providing a clear positioning reference for the installation of the clamping block. During the installation process, the operator only needs to align these holes to quickly and accurately place the clamping block in the predetermined position, avoiding installation difficulties or deviations caused by inaccurate positioning, and greatly improving installation efficiency.

[0010] Furthermore, the placement plate is provided with a first groove, and a first step structure is formed around the first groove. The movable plate is provided with a second groove, and a second step structure is formed around the second groove. The PCB abuts against the first step structure and / or the second step structure.

[0011] In the above scheme, the first groove on the placement plate and the first step structure on its periphery, and the second groove on the movable plate and the second step structure on its periphery, provide clear and precise installation position guidance for the PCB. During the assembly process, the operator only needs to align the PCB with the corresponding first step structure or second step structure to place it, which can quickly and accurately position the PCB in the appropriate position, greatly improving assembly efficiency and reducing assembly errors and time waste caused by inaccurate positioning.

[0012] Furthermore, the first step structure has several first slots on the side away from the clamping block.

[0013] In the above solution, the first slot makes it easier for operators to remove the PCB from the placement board. Compared with operating directly on a smooth surface, the presence of the first slot makes the application of force more precise and effective, greatly reducing the difficulty of operation and reducing operational errors and time waste caused by difficulty in grasping.

[0014] Furthermore, the second step structure has two second slots on the side away from the clamping block, and a connecting block is provided between the two second slots. The connecting block is connected to the push rod of the quick clamp.

[0015] In the above scheme, the quick clamp can accurately transmit force to the connecting block with the help of the push rod, and then act on the second step structure and the movable plate, so that the clamping block can perform more precise clamping operation on the PCB, avoiding PCB damage or insecure clamping caused by uneven force application. The second slot is designed to facilitate the operator to remove the PCB from the movable plate. The design of setting the connecting block between the two second slots makes full use of the limited space and makes the whole structure more compact.

[0016] Furthermore, the limiting block is in the shape of a straight line or an L-shape.

[0017] In the above solution, the straight-line limiting block is used to restrict the sides of the PCB, and the L-shaped limiting block is used to restrict the corner position of the PCB. This can effectively prevent the PCB from shaking or shifting, and improve the overall positioning accuracy of the PCB.

[0018] Furthermore, the support base plate is provided with a guide rail, and a slider is slidably mounted on the guide rail, the slider being connected to the movable plate.

[0019] In the above scheme, the guide rail provides a precise movement path for the slider, so that the movable plate can only move along the direction of the guide rail during the sliding process. This precise guiding effect avoids the movable plate from deviating or shaking during the movement, ensuring that the movable plate can reach the designated position stably and accurately, thereby improving the consistency and reliability of clamping.

[0020] This utility model discloses a PCB assembly clamping device with the advantages of simple operation, precise positioning and stable clamping of PCBs, and high flexibility. By pressing down the quick clamp, the push rod of the quick clamp pushes the movable plate towards the placement plate, causing the movable plate to abut against the placement plate. The clamping block, in conjunction with the limiting blocks on the movable block and / or the placement block, then limits and clamps the PCB. The simple operation enables rapid PCB clamping. The cooperation between the clamping block and the limiting block ensures reliable PCB clamping, preventing PCB shaking or displacement during assembly. This stable clamping effect helps improve assembly accuracy and quality, ensuring accurate installation of electronic components on the PCB, thereby improving product performance and reliability. PCBs can be placed alone on the movable plate, alone on the placement plate, or simultaneously on both the movable plate and the placement plate, increasing the flexibility of the device. Different PCB sizes can be assembled simultaneously on the movable plate and the placement plate, improving production efficiency. Attached Figure Description

Detailed Implementation

[0025] The following will describe in further detail a clamping device for PCB assembly according to specific embodiments and accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown in a preferred embodiment, a PCB assembly clamping device of the present invention includes a supporting base plate 1 and a placement plate 2, a quick clamp 3, a movable plate 4, and clamping blocks 5 mounted on the supporting base plate 1. The placement plate 2 and / or the movable plate 4 are provided with a plurality of limiting blocks 6. A plurality of clamping blocks 5 are mounted on one side of the movable plate 4 or the placement plate 2. The clamping blocks 5 cooperate with the limiting blocks 6 on the movable plate 4 and / or the placement plate 2 to clamp and limit the PCB. The end of the movable plate 4 away from the clamping blocks 5 is connected to the push rod of the quick clamp 3.

[0027] The support base plate 1 can be installed on any platform using screws or other fasteners. By pressing down the quick clamp 3, the push rod of the quick clamp 3 can push the movable plate 4 towards the placement plate 2, so that the movable plate 4 abuts against the placement plate 2. In this way, the clamping block 5 can cooperate with the movable block and / or the limiting block 6 on the placement block to limit and clamp the PCB. The operation is simple and can realize the quick clamping of the PCB. The quick clamp 3 is a conventional tool, and its principle and structure will not be described in detail here.

[0028] The cooperation between clamping block 5 and limiting block 6 can reliably clamp the PCB, preventing it from shaking or shifting during assembly. This stable clamping effect helps improve the accuracy and quality of assembly, ensuring that electronic components on the PCB can be accurately installed, thereby improving product performance and reliability. PCBs can be placed on the movable plate 4 alone, on the placement plate 2 alone, or on both the movable plate 4 and the placement plate 2 simultaneously, which increases the flexibility of the device. PCBs of different specifications can be placed on the movable plate 4 and the placement plate 2 simultaneously for assembly, which can improve production efficiency.

[0029] like Figure 2 As shown, in some embodiments, the clamping block 5 includes a first horizontal plate 51, a second horizontal plate 52, and a vertical plate 53. The vertical plate 53 is vertically disposed between the first horizontal plate 51 and the second horizontal plate 52. The clamping block 5 is configured as an axisymmetric structure with the vertical plate 53 as the axis of symmetry. The clamping block 5 has clamping grooves 54 formed on both sides of the vertical plate 53 for clamping the PCB. The clamping block 5 is configured as an axisymmetric structure with the vertical plate 53 as the axis of symmetry. The clamping plate has clamping grooves 54 formed on both sides of the vertical plate 53. In this way, when installed on the placement plate 2 or the movable plate 4, there is no need to consider the problem of reverse installation, which can improve the installation efficiency. Moreover, the clamping grooves 54 on both sides of the clamping plate can clamp the PCB on the placement plate 2 or the PCB on the movable plate 4, or clamp the PCB on the placement plate 2 and the movable plate 4 at the same time, which increases the flexibility of the device and can meet different production needs.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, the first horizontal plate 51 is provided with a first through hole 511, and the second horizontal plate 52 is provided with a second through hole 521 corresponding to the first through hole 511. The position where the movable plate 4 or the placement plate 2 is installed with the clamping block 5 is provided with an installation groove 7, and the installation groove 7 is provided with a connecting hole 71 corresponding to the first through hole 511 and the second through hole 521. The first through hole 511 on the first horizontal plate 51 and the second through hole 521 on the second horizontal plate 52 correspond to the connecting hole 71 on the installation groove 7 of the movable plate 4 or the placement plate 2, providing a clear positioning reference for the installation of the clamping block 5. During the installation process, the operator only needs to align these holes to quickly and accurately place the clamping block 5 in the predetermined position, avoiding installation difficulties or installation deviations caused by inaccurate positioning, and greatly improving installation efficiency.

[0031] like Figure 1 and Figure 3As shown, in some embodiments, the placement plate 2 has a first groove 21, and a first step structure 22 is formed around the first groove 21. The movable plate 4 has a second groove 41, and a second step structure 42 is formed around the second groove 41. The PCB abuts against the first step structure 22 and / or the second step structure 42. The first groove 21 on the placement plate 2 and the first step structure 22 around it, and the second groove 41 on the movable plate 4 and the second step structure 42 around it, provide clear and precise installation position guidance for the PCB. During the assembly process, the operator only needs to align the PCB with the corresponding first step structure 22 or second step structure 42 to quickly and accurately position the PCB in the appropriate position, greatly improving assembly efficiency and reducing assembly errors and time waste caused by inaccurate positioning.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, the first step structure 22 has a plurality of first slots 23 on the side away from the clamping block 5. The first slots 23 facilitate the operator to remove the PCB on the placement board 2. Compared with operating directly on a smooth surface, the presence of the first slots 23 makes the application of force more precise and effective, greatly reducing the difficulty of operation and reducing operational errors and time waste caused by difficulty in gripping.

[0033] like Figure 1 As shown, in some embodiments, the second step structure 42 has two second slots 43 on the side away from the clamping block 5, and a connecting block 44 is provided between the two second slots 43. The connecting block 44 is connected to the push rod of the quick clamp 3. The quick clamp 3 can accurately transmit force to the connecting block 44 with the help of the push rod, and then act on the second step structure 42 and the movable plate 4, so that the clamping block 5 can perform more precise clamping operation on the PCB, avoiding PCB damage or insecure clamping caused by uneven force application. The second slots 43 facilitate the operator to remove the PCB from the movable plate 4. The design of placing the connecting block 44 between the two second slots 43 makes full use of the limited space, making the whole structure more compact.

[0034] like Figure 1 As shown, in some embodiments, the limiting block 6 is in the shape of a straight line or an L-shape. The straight-shaped limiting block 6 is used to limit the sides of the PCB, and the L-shaped limiting block 6 is used to limit the corner position of the PCB, which can effectively prevent the PCB from shaking or shifting, and improve the overall positioning accuracy of the PCB.

[0035] like Figure 3As shown, in some embodiments, a guide rail 8 is provided on the support base plate 1, and a slider 9 is slidably mounted on the guide rail 8. The slider 9 is connected to the movable plate 4. The guide rail 8 provides a precise movement path for the slider 9, so that the movable plate 4 can only move along the direction of the guide rail 8 during sliding. This precise guiding effect prevents the movable plate 4 from deviating or wobbling during movement, ensuring that the movable plate 4 can reach the designated position stably and accurately, thereby improving the consistency and reliability of clamping.

[0036] The working principle and process of a PCB assembly clamping device of this utility model are as follows: When the PCB is placed on the placement plate 2, the clamping block 5 is installed on the movable plate 4. By pressing down the quick clamping device 3, the push rod pushes the movable plate 4 toward the placement plate 2, and one side of the PCB will pass into the clamping groove 54. The clamping block 5 on the movable plate 4, together with the limiting block 6 on the placement plate 2, realizes the clamping and limiting of the PCB. When the PCB is placed on the movable plate 4, the clamping block 5 is installed on the placement plate 2. By pressing down the quick clamping device 3, the push rod pushes the movable plate 4 toward the placement plate 2. One side of the PCB on the movable plate 4 will pass into the clamping groove 54. The clamping block 5 on the placement plate 2, together with the limiting block 6 on the movable plate 4, achieves clamping and limiting of the PCB. When PCBs are placed on both the movable plate 4 and the placement plate 2, the clamping block 5 can be first installed on the placement plate 2 to clamp and limit the PCBs on the placement plate 2. Then, by pressing down the quick clamp 3, the push rod will push the movable plate 4 toward the placement plate 2, and the clamping block 5 on the placement plate 2 will clamp and limit the PCBs on the movable plate 4. Alternatively, the clamping block 5 can be first installed on the movable plate 4 to clamp and limit the PCBs on the movable plate 4. Then, by pressing down the quick clamp 3, the push rod will push the movable plate 4 toward the placement plate 2, and the clamping block 5 on the movable plate 4 will clamp and limit the PCBs on the placement plate 2.
