Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing, specifically to a wedge clamping device. Background Technology
[0002] A circuit board, also known as a printed circuit board or PCB, is a type of board commonly found in the market. Common types include single-layer boards, double-layer boards, and multilayer boards. Circuit board manufacturing involves processes such as pattern transfer, browning, lamination, drilling, copper plating, electroplating, solder mask application, component soldering, and testing. In some manufacturing processes, the circuit board needs to be clamped to prevent displacement and avoid defects. Conventional clamping mechanisms often use guide rails or linear bearings as guides and cylinders as the power source to press down perpendicularly to the circuit board surface. These clamping mechanisms are space-consuming and complex. With large circuit boards, uneven force can easily occur on the board surface, leading to displacement or even damage during manufacturing. To ensure proper clamping, multiple power sources may be needed, further increasing the space required for the equipment. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a wedge-shaped clamping device.
[0004] This utility model is achieved using the following solution:
[0005] A wedge clamping device includes a pressing clamping mechanism, a supporting clamping mechanism disposed below the pressing clamping mechanism, and a driving mechanism for driving the pressing clamping mechanism. The pressing clamping mechanism includes a fixed frame, a fixed seat connected to the fixed frame, a driving seat movably connected to the fixed seat, a pressing seat connected to the fixed seat, and a first clamping member disposed at the bottom of the pressing seat. The pressing seat is located below the driving seat, the bottom surface of the driving seat is provided with a plurality of first wedge-shaped portions, and the top surface of the pressing seat is provided with a plurality of second wedge-shaped portions matching the first wedge-shaped portions. The driving mechanism is connected to the driving seat and is used to drive the driving seat to move horizontally. The supporting clamping mechanism has a second clamping member matching the first clamping member.
[0006] Furthermore, the pressing clamping mechanism also includes a guide reset assembly, which includes a guide rod connected to the pressing seat and a spring sleeved on the guide rod. The upper end of the guide rod extends through the fixed seat to above the top surface of the fixed seat. The upper end of the spring is connected to the top end of the guide rod, and the lower end of the spring is connected to the fixed seat.
[0007] Furthermore, the support clamping mechanism also includes a support base, and the second clamping member is disposed on the support base.
[0008] Furthermore, both the bottom surface of the first clamping member and the top surface of the second clamping member are provided with elastic clamping layers.
[0009] Furthermore, the elastic clamping layer is urethane.
[0010] Furthermore, a boss is provided on the support base, and the second clamping member is connected to the boss.
[0011] Furthermore, the driving mechanism includes a driving bracket, a driving component connected to the driving bracket, and a connecting rod connected to the output end of the driving component. The driving component is arranged in a horizontal direction, and the connecting rod is connected to the driving base.
[0012] Furthermore, the drive bracket is equipped with a sensor, and a detection block matching the sensor is connected to the connecting rod.
[0013] Furthermore, a guide seat is provided at the end of the bottom surface of the fixed seat, and a guide hole is formed between the guide seat and the fixed seat. The drive seat is provided with a guide portion that matches the guide hole.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] When the drive seat of this invention moves, each first wedge portion of the drive seat pushes the corresponding second wedge portion of the pressure seat, causing the first clamping member to move downward and cooperate with the second clamping member to achieve a clamping action. The moving distance is small, and there is no need to set up structures such as guide rails and linear bearings, which not only reduces the space occupied, but also reduces the overall structural complexity. At the same time, since each second wedge portion is pushed by the first wedge portion, the downward pressure of the first clamping member is uniform, preventing the circuit board from shifting.

Detailed Implementation
[0024] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0025] Example 1
[0026] Refer to 1 to Figure 6 The present invention provides a wedge clamping device, including a pressing clamping mechanism 1, a supporting clamping mechanism 2 disposed below the pressing clamping mechanism 1, and a driving mechanism 3 for driving the pressing clamping mechanism 1.
[0027] The pressing and clamping mechanism 1 includes a fixed frame 11, a fixed base 12 connected to the fixed frame 11, a drive base 13 movably connected to the fixed base 12, a pressing base 14 connected to the fixed base 12, and a first clamping member 15 disposed at the bottom of the pressing base 14. The pressing base 14 is located below the drive base 13. The bottom surface of the drive base 13 is provided with a plurality of first wedge-shaped portions 16, and the top surface of the pressing base 14 is provided with a plurality of second wedge-shaped portions 17 that match the first wedge-shaped portions 16. The drive mechanism 3 is connected to the drive base 13, and the drive mechanism 3 drives the drive base 13 to move in the horizontal direction. The supporting and clamping mechanism 2 has a second clamping member 21 that matches the first clamping member 15. When the drive seat 13 maintains its vertical position and moves horizontally, the first wedge 16 moves upward relative to the second wedge 17 (i.e., the first wedge 16 and the second wedge 17 are offset). At this time, the pressure seat 14 remains horizontal, which is equivalent to the first wedge 16 pushing the second wedge 17 downward. Ultimately, the drive seat 13 pushes the pressure seat 14 downward, thereby causing the first clamping member 15 to press down and cooperate with the second clamping member 21 to clamp the circuit board. During the movement of the drive seat 13, each first wedge 16 simultaneously pushes the corresponding second wedge 17, which also makes the pressure seat 14 evenly stressed, i.e., the downward pressure of the first clamping member 15 is uniform, preventing the circuit board from shifting.
[0028] A guide seat 19 is provided at one end of the bottom surface of the fixed base 12, and a guide hole 191 is formed between the guide seat 19 and the fixed base 12. The drive base 13 is provided with a guide portion 131 that matches the guide hole 191. In this embodiment, guide seats 19 are provided at both ends of the bottom surface of the fixed base 12, that is, guide holes 191 are provided at both ends, so as to... Figure 3 Taking the perspective of the left end as an example, the guide hole 191 at the left end is for the connecting rod 33 to pass through, while the guide part 131 at the right end passes through. Both ends have guidance, which also ensures the smoothness of the movement of the drive seat 13.
[0029] The pressing clamping mechanism 1 further includes a guide reset assembly 18. The guide reset assembly 18 includes a guide rod 181 connected to the pressing seat 14 and a spring 182 sleeved on the guide rod 181. The upper end of the guide rod 181 extends through the fixed seat 12 and above the top surface of the fixed seat 12. The upper end of the spring 182 is connected to the top end of the guide rod 181, and the lower end of the spring 182 is connected to the fixed seat 12. When the drive seat 13 pushes the pressing seat 14 downward, the guide rod 181 plays a guiding and stabilizing role, making the movement of the pressing seat 14 smooth. When the drive seat 13 resets, the pressing seat 14 also returns to its initial position under the elastic force of the spring 182.
[0030] The support and clamping mechanism 2 further includes a support base 22, and the second clamping member 21 is disposed on the support base 22. Specifically, the support base 22 is provided with a boss 23, and the second clamping member 21 is connected to the boss 23 by fasteners.
[0031] Both the bottom surface of the first clamping member 15 and the top surface of the second clamping member 21 are provided with an elastic clamping layer 4. In this embodiment, the elastic clamping layer 4 is urethane adhesive, specifically urethane adhesive with a hardness of 90-95 degrees.
[0032] The driving mechanism 3 includes a driving bracket 31, a driving component 32 connected to the driving bracket 31, and a connecting rod 33 connected to the output end of the driving component 32. The driving component 32 is arranged horizontally, and the connecting rod 33 is connected to the driving base 13. In this embodiment, the driving component 32 is a cylinder. Figure 3 Taking the perspective of [the device] as an example, the cylinder pulls the connecting rod 33 to move to the left, and the first wedge 16 pushes the second wedge 17 to move the lower pressure seat 14 downward, so that the first clamping member 15 and the second clamping member 21 cooperate to complete the clamping action. The drive seat 13 only needs to move a distance less than the length of the first wedge 16 to achieve the downward clamping action, without the need for guide rails or linear bearings, etc., making the structure simple and saving a lot of space.
[0033] The shoe-shaped clamping device provided by this utility model needs to be installed at the processing equipment or processing station during use. The fixing frame 11, drive frame, and support base 22 are connected to the corresponding connection structure at the processing station. In specific operation, the edge of the circuit board is first placed between the first clamping member 15 and the second clamping member 21. Then, the drive mechanism 3 pulls the drive base 13 to move, pushing the lower pressure base 14 down, so that the first clamping member 15 presses against the circuit board, clamping the circuit board. After the circuit board is fully clamped, drilling, cutting, and component installation can be performed.
[0034] Example 2
[0035] Reference Figures 1 to 6 The present invention provides a wedge clamping device, including a pressing clamping mechanism 1, a supporting clamping mechanism 2 disposed below the pressing clamping mechanism 1, and a driving mechanism 3 for driving the pressing clamping mechanism 1.
[0036] The pressing and clamping mechanism 1 includes a fixed frame 11, a fixed base 12 connected to the fixed frame 11, a drive base 13 movably connected to the fixed base 12, a pressing base 14 connected to the fixed base 12, and a first clamping member 15 disposed at the bottom of the pressing base 14. The pressing base 14 is located below the drive base 13. The bottom surface of the drive base 13 is provided with a plurality of first wedge-shaped portions 16, and the top surface of the pressing base 14 is provided with a plurality of second wedge-shaped portions 17 that match the first wedge-shaped portions 16. The drive mechanism 3 is connected to the drive base 13, and the drive mechanism 3 drives the drive base 13 to move in the horizontal direction. The supporting and clamping mechanism 2 has a second clamping member 21 that matches the first clamping member 15. When the drive seat 13 maintains its vertical position and moves horizontally, the first wedge 16 moves upward relative to the second wedge 17 (i.e., the first wedge 16 and the second wedge 17 are offset). At this time, the pressure seat 14 remains horizontal, which is equivalent to the first wedge 16 pushing the second wedge 17 downward. Ultimately, the drive seat 13 pushes the pressure seat 14 downward, thereby causing the first clamping member 15 to press down and cooperate with the second clamping member 21 to clamp the circuit board. During the movement of the drive seat 13, each first wedge 16 simultaneously pushes the corresponding second wedge 17, which also makes the pressure seat 14 evenly stressed, i.e., the downward pressure of the first clamping member 15 is uniform, preventing the circuit board from shifting.
[0037] A guide seat 19 is provided at one end of the bottom surface of the fixed base 12, and a guide hole 191 is formed between the guide seat 19 and the fixed base 12. The drive base 13 is provided with a guide portion 131 that matches the guide hole 191. In this embodiment, guide seats 19 are provided at both ends of the bottom surface of the fixed base 12, that is, guide holes 191 are provided at both ends, so as to... Figure 3 Taking the perspective of the left end as an example, the guide hole 191 at the left end is for the connecting rod 33 to pass through, while the guide part 131 at the right end passes through. Both ends have guidance, which also ensures the smoothness of the movement of the drive seat 13.
[0038] The pressing clamping mechanism 1 further includes a guide reset assembly 18. The guide reset assembly 18 includes a guide rod 181 connected to the pressing seat 14 and a spring 182 sleeved on the guide rod 181. The upper end of the guide rod 181 extends through the fixed seat 12 and above the top surface of the fixed seat 12. The upper end of the spring 182 is connected to the top end of the guide rod 181, and the lower end of the spring 182 is connected to the fixed seat 12. When the drive seat 13 pushes the pressing seat 14 downward, the guide rod 181 plays a guiding and stabilizing role, making the movement of the pressing seat 14 smooth. When the drive seat 13 resets, the pressing seat 14 also returns to its initial position under the elastic force of the spring 182.
[0039] The support and clamping mechanism 2 further includes a support base 22, and the second clamping member 21 is disposed on the support base 22. Specifically, the support base 22 is provided with a boss 23, and the second clamping member 21 is connected to the boss 23 by fasteners.
[0040] Both the bottom surface of the first clamping member 15 and the top surface of the second clamping member 21 are provided with an elastic clamping layer 4. In this embodiment, the elastic clamping layer 4 is urethane adhesive, specifically urethane adhesive with a hardness of 90-95 degrees.
[0041] The driving mechanism 3 includes a driving bracket 31, a driving component 32 connected to the driving bracket 31, and a connecting rod 33 connected to the output end of the driving component 32. The driving component 32 is arranged horizontally, and the connecting rod 33 is connected to the driving base 13. In this embodiment, the driving component 32 is a cylinder. Figure 3 Taking the perspective of [the device] as an example, the cylinder pulls the connecting rod 33 to move to the left, and the first wedge 16 pushes the second wedge 17 to move the lower pressure seat 14 downward, so that the first clamping member 15 and the second clamping member 21 cooperate to complete the clamping action. The drive seat 13 only needs to move a distance less than the length of the first wedge 16 to achieve the downward clamping action, without the need for guide rails or linear bearings, etc., making the structure simple and saving a lot of space.
[0042] The drive bracket 31 is equipped with a sensor 34, and a detection block 35 matching the sensor 34 is connected to the connecting rod 33. In this embodiment, the sensor 34 is a contact sensor. When the cylinder pulls the connecting rod 33 to the left, the detection block 35 and the sensor 34 come into contact, and the distance the drive seat 13 moves to the left can be measured, thereby calculating the thickness of the clamped product while pressing it.
[0043] The shoe-shaped clamping device provided by this utility model needs to be installed at the processing equipment or processing station during use. The fixing frame 11, drive frame, and support base 22 are connected to the corresponding connection structure at the processing station. In specific operation, the edge of the circuit board is first placed between the first clamping member 15 and the second clamping member 21. Then, the drive mechanism 3 pulls the drive base 13 to move, pushing the lower pressure base 14 down, so that the first clamping member 15 presses against the circuit board, clamping the circuit board. After the circuit board is fully clamped, drilling, cutting, and component installation can be performed.
[0044] When the drive seat 13 of this invention moves, each first wedge portion 16 of the drive seat 13 pushes the corresponding second wedge portion 17 of the pressure seat 14, causing the first clamping member to move downward and cooperate with the second clamping member 21 to achieve a clamping action. The moving distance is small, and there is no need to set up structures such as guide rails and linear bearings, which not only reduces the space occupied, but also reduces the overall structural complexity. At the same time, since each second wedge portion 17 is pushed by the first wedge portion 16, the downward pressure of the first clamping member 15 is uniform, preventing the circuit board from shifting.
