Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive rubber spring processing technology, specifically an SMT conductive rubber spring trimming device. Background Technology
[0002] SMT conductive rubber springs are conductive contact terminals that can be reflow soldered onto PCBs (printed circuit boards) using SMT (surface mount technology). They are typically made of silicone as the filler and metal plating as the inner and outer layers, and are processed at high temperatures. These springs have excellent elasticity and can provide buffering and grounding functions while ensuring conductivity.
[0003] During the cutting process of existing SMT conductive rubber springs, due to their different sizes, the position of the positioning block needs to be manually adjusted. This not only reduces work efficiency but also easily leads to deviations in the position of the positioning block, resulting in uneven edges or inconsistent sizes of the springs, thus affecting the precision and accuracy of the cutting.
[0004] Therefore, those skilled in the art have provided an SMT conductive rubber spring edge trimming device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide an SMT conductive rubber spring edge trimming device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An SMT conductive rubber spring trimming device includes a main body with a feed inlet on one side. A conveyor belt is installed inside the main body, and a positioning mechanism is located at the top of the conveyor belt. The positioning mechanism includes a mounting plate fixedly connected to the top of the conveyor belt. A telescopic push rod is fixedly connected to the bottom of the mounting plate, a connector is fixedly connected to the bottom of the telescopic push rod, a positioning block is fixedly connected to the bottom of the connector, a wear-resistant pad is fixedly connected to the bottom of the positioning block, and a laser positioner is fixedly connected to one side of the positioning block. By installing the positioning mechanism, the spring can be precisely positioned during trimming. The telescopic push rod can drive the positioning block to move precisely up and down, achieving precise positioning of conductive rubber springs of different thicknesses, reducing errors during trimming, and improving trimming accuracy and precision.
[0008] As a further embodiment of this utility model: a fixed plate is fixedly connected to one side of the conveyor belt, a support rod is fixedly connected to one side of the fixed plate, a groove is provided at the bottom of the support rod, a slider is movably connected inside the groove, a pneumatic rod is fixedly connected to the bottom of the slider, a mounting frame is fixedly connected to the bottom of the pneumatic rod, a cutting tool is fixedly connected to the bottom of the mounting frame, and protective blocks are fixedly connected to both sides of the mounting frame. The movable connection design between the groove at the bottom of the support rod and the slider allows the pneumatic rod and the connected cutting tool to move freely in the vertical direction, which not only improves the flexibility of the cutting tool, but also makes the cutting process more accurately adaptable to springs of different thicknesses and sizes, ensuring edge cutting accuracy, thereby improving the flexibility and accuracy of the device in use.
[0009] As a further improvement of this utility model: grooves are respectively provided on both sides of the conveyor belt, and a collection chamber is provided at the bottom of the groove. A blower is fixedly connected to one side of the main body of the device, and a blower pipe is fixedly connected to one end of the blower. The groove design on both sides of the conveyor belt provides a natural flow direction for the debris generated during the trimming process. When the cutting tool is trimming, the generated debris will flow along the groove to the collection chamber, reducing the accumulation of debris inside the device and avoiding the impact of debris on subsequent trimming operations.
[0010] As a further improvement of this utility model: a vacuum pump is fixedly connected to the top of the main body of the device, one end of the vacuum pump is fixedly connected to a suction pipe, one end of the suction pipe is fitted with a filter screen, and the other end of the vacuum pump is fixedly connected to a purification chamber. The vacuum pump generates negative pressure through the suction pipe, sucking the debris and dust generated during the trimming process into the device, effectively reducing the accumulation of debris and dust pollution in the working area, ensuring the accuracy of the trimming process, and thus improving trimming precision and efficiency.
[0011] As a further improvement of this utility model: a transparent observation window is provided on one side of the main body of the device, a control panel is provided at the bottom of the transparent observation window, and an emergency button is provided on one side of the control panel. Through the control panel, the operator can easily adjust the trimming parameters and intuitively observe the trimming process. In case of an emergency during the trimming process, the work can be stopped immediately by pressing the emergency button, thereby improving trimming efficiency and accuracy and ensuring safety during the trimming process.
[0012] As a further improvement of this utility model: the main body of the device is provided with a slot, the slot is fitted with a mounting frame, the mounting frame is fitted with an LED light group, and a power interface is provided on one side of the transparent observation window. In use, the operator can adjust the brightness of the LED light group through the control panel to provide bright and uniform light to the inside of the main body of the device, illuminating the trimming area, so that the operator can clearly observe the positioning of the spring, the movement of the cutting tool, and the collection of debris, thereby improving trimming accuracy and efficiency.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By installing a positioning mechanism, the spring sheet can be accurately positioned during cutting. The telescopic push rod can drive the positioning block to move up and down precisely, so as to accurately position conductive rubber spring sheets of different thicknesses, reduce errors in the cutting process, and improve cutting accuracy and precision.
[0015] The sliding groove at the bottom of the support rod and the movable connection design of the slider allow the pneumatic rod and the connected cutting tool to move freely in the vertical direction. This not only improves the flexibility of the cutting tool, but also makes the cutting process more accurate to adapt to springs of different thicknesses and sizes, ensuring the cutting accuracy and thus improving the flexibility and accuracy of the device in use.
[0016] During use, operators can adjust the brightness of the LED lights via the control panel to provide bright and uniform light to the interior of the device, illuminating the trimming area. This allows operators to clearly observe the positioning of the spring clips, the movement of the cutting blades, and the collection of debris, thereby improving trimming accuracy and efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0024] Reference Figure 1-5This embodiment provides an SMT conductive rubber spring edge trimming device, including a device body 1. A feed inlet 2 is provided on one side of the device body 1. A conveyor belt 3 is installed inside the device body 1. A positioning mechanism 4 is provided on the top of the conveyor belt 3. The positioning mechanism 4 includes a mounting plate 401, which is fixedly connected to the top of the conveyor belt 3. A telescopic push rod 402 is fixedly connected to the bottom of the mounting plate 401. A connector 403 is fixedly connected to the bottom of the telescopic push rod 402. A positioning block 404 is fixedly connected to the bottom of the connector 403. A wear-resistant pad 405 is fixedly connected to the bottom of the positioning block 404. A laser positioner 406 is fixedly connected to one side of the positioning block 404. A fixing plate 5 is fixedly connected to one side of the conveyor belt 3. A support rod 6 has a groove 7 at its bottom, and a slider 8 is movably connected inside the groove 7. A pneumatic rod 9 is fixedly connected to the bottom of the slider 8. The pneumatic rod 9 can be a cylinder-driven telescopic rod or an electrically driven electric push rod. A mounting bracket 10 is fixedly connected to the bottom of the pneumatic rod 9, and a cutting tool 11 is fixedly connected to the bottom of the mounting bracket 10. Protective blocks 12 are fixedly connected to both sides of the mounting bracket 10. Grooves 13 are opened on both sides of the conveyor belt 3, and a collection chamber 14 is set at the bottom of the groove 13. A blower 15 is fixedly connected to one side of the main body 1 of the device, and a blower pipe 16 is fixedly connected to one end of the blower 15. A vacuum pump 17 is fixedly connected to the top of the main body 1 of the device, and a suction pipe 18 is fixedly connected to one end of the vacuum pump 17. One end of the device is fitted with a filter screen 19, and the other end of the vacuum pump 17 is fixedly connected to a purification chamber 20. The SMT conductive rubber spring sheet to be trimmed enters the interior of the device body 1 through the feed port 2 and is transported by the conveyor belt 3. The conveyor belt 3 transports the spring sheet to the position to be trimmed. The telescopic push rod 402 can extend and retract according to the thickness of the spring sheet, causing the positioning block 404 and the wear-resistant pad 405 to contact the spring sheet and fix its position. At the same time, the laser positioner 406 is installed on one side of the positioning block and can emit a laser beam to accurately indicate the position of the spring sheet, ensuring that the trimming cutter can cut accurately. Then, the slider 8 slides inside the slide groove 7, driving the pneumatic rod 9 to move and adjust the cutting position. When it moves to the designated position, the pneumatic rod 9 extends and retracts, causing the cutting cutter 11 to extend and retract, fixing the position. The spring clips are cut, and protective blocks 12 are installed on both sides of the cutting blade 11 to prevent debris from splashing during the cutting process. The debris generated during the cutting process can fall into the bottom collection chamber 14 through the grooves 13 on both sides of the conveyor belt 3. At the same time, the blower 15 is started, and the debris in the cutting area is blown by the blower pipe 16 so that it can fall into the collection chamber 14. The dust generated during the blowing is sucked in by the vacuum pump 17 when it is started, which generates negative pressure through the suction pipe 18. The sucked debris and dust first pass through the filter screen 19. Large debris is blocked outside the filter screen 19, while fine dust enters the purification chamber 20 through the filter screen 19 for further treatment to ensure that the air emitted into the atmosphere meets environmental protection requirements.

The pneumatic rod 9 then drives the cutting blade 11 to descend and perform the trimming operation. The operator monitors the trimming process in real time through the transparent observation window 21 and adjusts the parameters on the control panel 22 as needed. In case of emergency, the operator can immediately press the emergency button 23 to stop the device.
