Abstract
Description
Technical Field
[0001] The present application relates to the field of circuit board assembly, and in particular to a tapping and stamping fixture. Background Art
[0002] In the electronics manufacturing industry, the connection between a circuit board and pins is an important link. Traditional methods for connecting a circuit board and pins rely mostly on manual operations, which are not only inefficient but also difficult to guarantee the connection quality.
[0003] Currently, the commonly used method for connecting a circuit board and pins is to use a tapping and stamping fixture. The staff first places the pins on the material plate, then covers the circuit board onto the pins, and then manually drives the pressing plate to stamp the circuit board to achieve the connection between the pins and the circuit board. This connection method requires the staff to press the handle of the pressing plate two or even three times, with low production efficiency. Moreover, since the force control depends entirely on personal experience when manually pressing the handle, it is difficult to control the pressing force. When the force is too large, it will cause excessive stamping of the circuit board and pins; when the force is too small, a tight connection cannot be achieved. There is inaccurate force control, which easily leads to over-stamping or under-stamping, affecting the product quality. Utility Model Content
[0004] In order to improve the connection efficiency and quality between the circuit board and pins, the present application provides a tapping and stamping fixture.
[0005] The tapping and stamping fixture provided by the present application adopts the following technical solutions:
[0006] A tapping and stamping fixture includes a frame, a material plate, a positioning mechanism, a pressing plate, and a cylinder. The material plate is arranged on the frame. The positioning mechanism is arranged on the material plate and is used to position the pins and the circuit board in a to-be-connected state on the material plate. The pressing plate is slidably arranged on the frame and is used to stamp on the circuit board on the material plate. The cylinder is arranged on the frame and is connected to the pressing plate.
[0007] By adopting the above technical solutions, the staff positions the pins and the circuit board in a to-be-connected state on the material plate through the positioning mechanism, and then controls the cylinder to start. The cylinder drives the pressing plate to stamp on the circuit board on the material plate, thereby realizing the connection between the pins and the circuit board. By setting the force of the cylinder driving the pressing plate to stamp, the force of each time the pressing plate stamps the circuit board can be controlled to maintain accuracy and consistency, and manual pressing is not required, effectively improving the connection efficiency and quality between the circuit board and pins.
[0008] Optionally, the positioning mechanism includes positioning blocks. Two positioning blocks are arranged at intervals on the material plate, and a plurality of positioning holes for inserting the pins are formed on both of the two positioning blocks.
[0009] By adopting the above technical solution, the staff inserts the pins into the positioning holes, and the side walls of the positioning holes position the pins, improving the stability of the pins. Then the staff buckles the circuit board onto the positioning block, aligning the multiple pins with the multiple holes on the circuit board respectively, so that the pins and the circuit board can be positioned in a state to be connected on the material board.
[0010] Optionally, the material board is slidably arranged on the frame, and a sliding component for driving the material board to slide is arranged on the frame.
[0011] By adopting the above technical solution, the staff first drives the material board to slide away from the pressing plate through the sliding component, and the material board drives the positioning block to slide away from the pressing plate. Then the staff assembles the pins and the circuit board, improving the safety of the staff when assembling the pins and the circuit board onto the positioning block.
[0012] Optionally, the sliding component includes a motor and a lead screw. The motor is arranged on the frame, the lead screw is coaxially arranged on the output shaft of the motor, and the lead screw is threadedly connected to the material board.
[0013] By adopting the above technical solution, the output shaft of the motor rotates forward and backward, which can drive the lead screw to rotate forward or backward, and then the material board slides on the frame in a direction close to or away from the pressing plate.
[0014] Optionally, clamping blocks for abutting against the circuit board are respectively arranged on the two positioning blocks, and the distance between the two clamping blocks is the same as the width of the circuit board.
[0015] By adopting the above technical solution, when the staff buckles the circuit board onto the positioning block, the two clamping blocks respectively abut against both sides of the circuit board, guiding the circuit board and improving the convenience of the staff when buckling the circuit board onto the positioning block.
[0016] Optionally, the clamping block is slidably arranged on the positioning block, and a convex block is arranged on the clamping block. When the clamping block slides to abut against the positioning block and the circuit board abuts against the convex block, the holes of the multiple connecting pins on the circuit board are just opposite to the multiple pins on the positioning block.
[0017] By adopting the above technical solution, the staff slides the clamping block to abut against the positioning block, and then abuts the circuit board against the convex block. At this time, the holes of the multiple connecting pins on the circuit board are just opposite to the multiple pins on the positioning block. Then the circuit board can be moved down to buckle the circuit board onto the positioning block, improving the convenience of the staff in aligning the circuit board with the pins. After the circuit board and the pins are stamped, sliding the clamping block away from the positioning block can reduce the influence of the clamping block on the staff when taking away the circuit board.
[0018] Optionally, jacks are formed in the material plate, and positioning posts for inserting into the jacks are arranged on the pressing plate.
[0019] By adopting the above technical solution, when the pressing plate is driven by the air cylinder to press onto the circuit board, the positioning posts are inserted into the jacks, and the side walls of the jacks guide the positioning posts, thereby guiding the pressing plate and improving the stability and accuracy of the pressing plate when pressing onto the circuit board.
[0020] Optionally, a pressure sensor is arranged on the pressing plate.
[0021] By adopting the above technical solution, when the pressing plate presses the circuit board, the pressure sensor detects the pressing force of the pressing plate, facilitating the staff to control the pressing force of the pressing plate.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By setting the force of the air cylinder driving the pressing plate to press, the force of the pressing plate pressing the circuit board each time can be controlled to be accurate and consistent, and manual pressing is not required, effectively improving the connection efficiency and connection quality between the circuit board and the pins;
[0024] 2. By the sliding component driving the material plate to slide away from the pressing plate, the material plate drives the positioning block to slide away from the pressing plate, and then the staff assembles the pins and the circuit board, improving the safety of the staff when assembling the pins and the circuit board onto the positioning block;
[0025] 3. When the circuit board is abutted against the convex block, at this time, the holes of the multiple connection pins on the circuit board are just opposite to the multiple pins on the positioning block, and then the circuit board can be moved downward to buckle the circuit board onto the positioning block, improving the convenience of the staff in aligning the circuit board with the pins.

[0029] The following further describes the present application in detail Figure 1-2 with reference to the attached
[0030] An embodiment of the present application discloses a foot-knocking stamping fixture.
[0031] Referring to Figure 1 , the foot-knocking stamping fixture includes a frame 1, a material plate 2, a positioning mechanism 3, a pressing plate 4, a cylinder 5, and a sliding assembly 6.
[0032] Referring to Figure 1 , a chute is horizontally opened on the frame 1, and the material plate 2 is slidably installed on the inner wall of the chute; the positioning mechanism 3 is installed on the material plate 2, and the positioning mechanism 3 is used to position the pins and the circuit board in a to-be-connected state on the material plate 2; the pressing plate 4 is slidably installed on the frame 1 in the vertical direction, the cylinder 5 is installed on the frame 1, and the piston rod of the cylinder 5 is connected to the pressing plate 4. In other embodiments, a linear driving mechanism such as a hydraulic cylinder or an electric push rod can also be used to drive the pressing plate 4; the sliding assembly 6 is installed on the frame 1, and the sliding assembly 6 is used to drive the material plate 2 to slide.
[0033] The worker first drives the material plate 2 to slide away from the pressing plate 4 through the sliding assembly 6, then assembles the pins and the circuit board, positions the pins and the circuit board in a to-be-connected state on the material plate 2 through the positioning mechanism 3, and then drives the material plate 2 to slide towards the direction close to the bottom of the pressing plate 4 through the sliding assembly 6 until it is below the pressing plate 4, and then starts the cylinder 5. The piston rod of the cylinder 5 extends to drive the pressing plate 4 to stamp on the circuit board, so that the pins and the circuit board in a to-be-connected state on the circuit board can be stamped and connected. By setting the force with which the cylinder 5 drives the pressing plate 4 to stamp, the force of each time the pressing plate 4 stamps on the circuit board can be controlled to maintain accuracy and consistency, and manual operation and pressing are not required, effectively improving the connection efficiency and connection quality between the circuit board and the pins.
[0034] Referring to Figure 1 , the sliding assembly 6 includes a motor 61 and a lead screw 62. The motor 61 is installed on the frame 1. In this embodiment, the motor 61 is a servo motor 61. The lead screw 62 is coaxially installed on the output shaft of the motor 61, and the lead screw 62 is threadedly connected to the material plate 2.
[0035] The worker starts the motor 61 to drive the output shaft of the motor 61 to rotate forward or backward, which can drive the lead screw 62 to rotate forward or backward, and further make the material plate 2 slide towards the direction close to the bottom of the pressing plate 4 or away from the bottom of the pressing plate 4, so that the worker can assemble the pins and the circuit board at a position where the material plate 2 is far from the pressing plate 4, improving the safety of the worker when assembling the pins and the circuit board.
[0036] Referring to Figure 1 , Figure 2 , a plurality of jacks 21 are opened on the material plate 2, and a plurality of positioning posts 9 are installed on the pressing plate 4. The plurality of positioning posts 9 correspond to the plurality of jacks 21 one by one, and the plurality of positioning posts 9 are respectively used to insert into the plurality of jacks 21.
[0037] When the pressing plate 4 is driven by the air cylinder 5 to move downward to stamp the circuit board, multiple positioning posts 9 on the pressing plate 4 are respectively inserted into multiple jacks 21, and the side walls of the jacks 21 guide the positioning posts 9, thereby guiding the movement of the pressing plate 4 and improving the stability and accuracy when the pressing plate 4 is stamped onto the circuit board.
[0038] Refer to Figure 1 , a pressure sensor is installed on the pressing plate 4. In this embodiment, a display panel is also installed on the frame 1, and the display panel is electrically connected to the pressure sensor. When the pressing plate 4 stamps the circuit board, the pressure sensor detects the pressing force of the pressing plate 4, and then transmits an electrical signal to the display panel. The display panel displays the pressing force of the pressing plate 4, and the staff can observe the pressing force of the pressing plate 4 at any time, improving the convenience for the staff to control the pressing force of the pressing plate 4.
[0039] Refer to Figure 1 、 Figure 2 , the positioning mechanism 3 includes two positioning blocks 31. The two positioning blocks 31 are installed at intervals on the material plate 2, and multiple positioning holes 311 are opened on both positioning blocks 31 for the pins to be inserted.
[0040] The staff first inserts multiple pins into multiple positioning holes 311 respectively, and then buckles the circuit board onto the positioning blocks 31, so that multiple holes on the circuit board respectively correspond to multiple pins one by one, and multiple pins are respectively partially inserted into multiple holes on the circuit board, then the pins and the circuit board can be positioned in a connected state on the material plate 2. Through the positioning of the pins by the side walls of the positioning holes 311 and the positioning of the circuit board by multiple pins, the accuracy of the placement positions of multiple pins and the circuit board and the stability on the material plate 2 are effectively improved.
[0041] Refer to Figure 1 、 Figure 2 , sliding blocks 7 are slidably installed on both positioning blocks 31 along the sliding direction of the material plate 2. The distance between the two sliding blocks 7 is the same as the width of the circuit board. The two sliding blocks 7 are used to respectively abut against the side walls on both sides of the circuit board. A convex block 8 is installed on the sliding block 7. When the sliding block 7 slides to abut against the positioning block 31 and the circuit board abuts against the convex block 8, the holes of multiple connecting pins on the circuit board are just opposite to multiple pins on the positioning block 31.
[0042] After the staff inserts multiple pins into multiple positioning holes 311 respectively, they pull the clamping block 7 so that the clamping block 7 abuts against the positioning block 31. Then, they snap the moving circuit board between the two clamping blocks 7 and make the circuit board abut against the bump 8. At this time, the holes of the multiple connection pins on the circuit board are just aligned with the multiple pins on the positioning block 31. Then, the staff can directly press the circuit board to insert the multiple pins into the multiple holes on the circuit board respectively, realizing the snap-in installation of the circuit board. Through the limitation and guidance of the circuit board by the two clamping blocks 7 and the positioning of the circuit board by the bump 8, the convenience and accuracy of the staff when snapping the circuit board onto the positioning block 31 after aligning the circuit board with the pins are effectively improved. After the circuit board and the pins are stamped, the staff can also pull the clamping block 7 to make the clamping block 7 away from the circuit board, and then remove the circuit board, reducing the influence of the clamping block 7 abutting against the circuit board on the staff removing the circuit board.
[0043] The implementation principle of a pin-pounding stamping jig in an embodiment of this application is as follows: The staff inserts multiple pins into multiple positioning holes 311 respectively, then pulls the clamping block 7 so that the clamping block 7 abuts against the positioning block 31, then snaps the circuit board between the two clamping blocks 7 and makes the circuit board abut against the bump 8. Then, by pressing the circuit board, the circuit board and the pins can be positioned in a state to be connected on the material plate 2. Then, the staff starts the motor 61 to make the material plate 2 drive the circuit board to move under the pressing plate 4, and then starts the cylinder 5. The cylinder 5 drives the pressing plate 4 to stamp on the circuit board. Without manual pressing, the connection between the pins and the circuit board can be realized. By setting the force with which the cylinder 5 drives the pressing plate 4 to stamp, the staff can control the force of the pressing plate 4 stamping on the circuit board each time to maintain accuracy and consistency, effectively improving the connection efficiency and connection quality between the circuit board and the pins.
[0044] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
