Description

Technical Field

[0001] This utility model relates to the technical field of potentiometer assembly equipment, specifically to a brush assembly mechanism for a sliding potentiometer. Background Technology

[0002] A potentiometer is a resistive element with three leads whose resistance can be adjusted according to a certain pattern. A potentiometer typically consists of a resistive element and a movable brush. Its main function is to adjust the magnitude of voltage and current. Its working principle involves manually adjusting the rotating shaft or slider to change the position of the moving contact on the resistive element, thus changing the resistance between the moving contact and any of the fixed terminals, thereby altering the voltage and current.

[0003] A sliding potentiometer includes a housing, a push handle, a brush, and a coated carbon sheet. The brush moves within the potentiometer to change its resistance or output voltage. In the prior art, the brush strip is generally packaged in rolls. During assembly, the brushes need to be stamped off the strip sequentially and then assembled and fixed to the push handle. Therefore, a brush assembly mechanism for sliding potentiometers is required. Summary of the Invention

[0004] The purpose of this invention is to provide a brush assembly mechanism for a sliding potentiometer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brush assembly mechanism for a sliding potentiometer, comprising a support frame, a first conveying mechanism for driving the brush strip to slide horizontally at the top of the support frame, a punching separation mechanism for punching and separating the brush from the strip, and a waste collection mechanism for collecting waste. Above the punching separation mechanism is a second conveying mechanism for sending out the punched brush.

[0006] Furthermore, the punching and separating mechanism includes a limiting frame, a brush punching head, and a driving module that drives the two to move synchronously in opposite directions, respectively, which are movably disposed at the upper and lower ends of the support frame. The limiting frame and the brush punching head are respectively located at the upper and lower ends of the brush strip. The brush punching head is configured to conform to the shape of the brush and is used to punch and separate the brush from the strip. The limiting frame is used to press down on the edge of the brush strip during punching.

[0007] Furthermore, the drive module includes a first movable rod and a second movable rod that are fixedly connected to the brush punching head and the limiting frame, respectively. A fixed seat is provided below the support frame, and the first movable rod and the second movable rod are slidably connected to the fixed seat vertically. The front and rear ends of the fixed seat are horizontally slidably provided with a first movable plate and a second movable plate through a first linear drive member, and the first linear drive member is used to drive the first movable plate and the second movable plate to slide horizontally synchronously. The first movable plate and the second movable plate are respectively provided with a first guide sliding hole and a second guide sliding hole that are inclined in opposite directions in the vertical direction. The first movable rod is slidably connected to the first guide sliding hole through a fixed rod, and the second movable rod is slidably connected to the second guide sliding hole through a fixed rod.

[0008] Furthermore, the first conveying mechanism includes a movable block that is horizontally slidably disposed on the top of the support frame via a third linear drive member and a first positioning rod that is vertically slidably disposed on the movable block via a second linear drive member. A plurality of positioning through holes adapted to the first positioning rod are provided at equal intervals at the edge of the brush strip.

[0009] Furthermore, the waste collection mechanism includes a discharge chute inclined downward on one side of the support frame and a waste punching head that is movably mounted above the discharge chute via a fourth linear drive, for punching the waste strip after it is punched down by the brush into multiple segments for collection.

[0010] Furthermore, the second conveying mechanism includes a feeding head, a second positioning rod that is movably mounted on the feeding head via a fifth linear drive, a sixth linear drive for adjusting the height of the feeding head, and a seventh linear drive for adjusting the horizontal position of the feeding head.

[0021] Please see Figure 1-6 This utility model provides an embodiment of a brush assembly mechanism for a sliding potentiometer, comprising a support frame 1, a first conveying mechanism 3 for driving the brush strip to slide horizontally at the top of the support frame 1, a punching and separating mechanism 2 for punching and separating the brush from the strip, and a waste collection mechanism 4 for collecting waste. The support frame 1 is provided with a baffle for blocking and limiting the brush strip. (See attached drawing.) Figure 2-3 The first conveying mechanism 3 includes a movable block 304 horizontally slidably mounted on the top of the support frame 1 via a third linear drive 303 and a first positioning rod 301 vertically slidably mounted on the movable block 304 via a second linear drive 302. Several positioning through holes adapted to the first positioning rod 301 are evenly spaced along the edge of the brush strip. During operation, the third linear drive 303 retracts, causing the movable block 304 to move to the rightmost end. The second linear drive 302 extends, pushing the movable block 304 downwards into the positioning through holes at the edge of the brush strip. Then, the third linear drive 303 extends, pushing the movable block 304 and the first positioning rod 301 to move horizontally, thereby driving the strip to move horizontally. When the first positioning rod 301 moves to the leftmost end, the second linear drive 302 and the third linear drive 303 retract and reset, repeating the above actions to convey the strip.

[0022] Reference Appendix Figure 2-3The punching and separating mechanism 2 includes a limiting frame 202, a brush punching head 201, and a drive module that drives the two to move synchronously in opposite directions, respectively, which are movably arranged at the upper and lower ends of the support frame 1. The limiting frame 202 and the brush punching head 201 are located at the upper and lower ends of the brush strip, respectively. The brush punching head 201 is set in the same shape as the brush and is used to punch and separate the brush from the strip. The limiting frame 202 is used to press down on the edge of the brush strip during punching. Specifically, the drive module includes a first movable rod 203 and a second movable rod 204, which are respectively fixedly connected to the brush punching head 201 and the limiting frame 202. A fixed seat 205 is provided below the support frame 1, and the first movable rod 203 and the second movable rod 204 are both slidably connected to the fixed seat 205 vertically. The front and rear ends of the fixed seat 205 are horizontally slidably connected to a first movable plate 206 and a second movable plate 207 via a first linear drive member 208. The first linear drive member 208 is used to drive the first movable plate 206 and the second movable plate 207 to slide horizontally synchronously. The plate 207 is provided with a first guide sliding hole 2061 and a second guide sliding hole 2071 that are inclined in opposite directions in the vertical direction. The first movable rod 203 is slidably connected to the first guide sliding hole 2061 through a fixed rod, and the second movable rod 204 is slidably connected to the second guide sliding hole 2071 through a fixed rod. When working, when the first linear drive member 208 drives the first movable plate 206 and the second movable plate 207 to move horizontally, it can drive the first movable rod 203 and the second movable rod 204 to move in opposite directions in the vertical direction, and then drive the brush punch head 201 and the limiting frame 202 to move in opposite directions.

[0023] Reference Appendix Figure 4 The waste collection mechanism 4 includes a discharge chute 403 inclined downward on one side of the support frame 1 and a waste punching head 401 that is movably mounted above the discharge chute 403 by a fourth linear drive 402. After the brush is removed, the material strip is horizontally moved to the bottom of the waste punching head 401. The fourth linear drive 402 drives the waste punching head 401 to move downward, which can cut the waste strip into multiple segments for easy collection.

[0024] Reference Appendix Figure 5-6Above the punching and separating mechanism 2, there is a second conveying mechanism 5 for sending out the punched brushes. The second conveying mechanism 5 includes a feeding head 501, a second positioning rod 502 that is movably mounted on the feeding head 501 via a fifth linear drive 503, a sixth linear drive 504 that adjusts the height of the feeding head 501, and a seventh linear drive 505 that adjusts the horizontal position of the feeding head 501. The second positioning rod 502 extends through the feeding head 501 to the bottom of the feeding head 501 and is adapted to the brush. The second positioning rod 502 is inserted into the positioning hole on the brush to fix it. When the seventh linear drive 505 drives the second positioning rod 502 to move upward relative to the feeding head 501, the brush can be pushed down from the bottom of the feeding head 501.

[0025] In this embodiment, the linear drive component can specifically be a cylinder.

[0026] Working principle: The brush strip enters horizontally into the top of the support frame 1. The second linear drive 302 extends and drives the first positioning rod 301 to move downward and insert into the through hole at the edge of the strip. Then, the third linear drive 303 pushes the movable block 304 to move horizontally, thereby driving the strip to move horizontally. When the strip moves between the brush punching head 201 and the limiting frame 202, the first linear drive 208 pushes the first movable plate 206 and the second movable plate 207 to move horizontally. The first movable rod 203 and the second movable rod 204 are slidably connected to the first guide sliding hole 2061 and the second guide sliding hole 2071 respectively through the fixed post, thereby driving the first movable rod 203 and the second movable rod 204 to move vertically, i.e., the brush punching. The head 201 punches the strip upwards, and the limiting frame 202 presses the edge of the strip to limit it. After punching, the brush punching head 201 moves downwards, and the limiting frame 202 moves upwards, which can drive the strip to continue to move horizontally. The waste punching head 402 drives the fourth linear drive 401 to move downwards to punch the waste. The waste is collected through the discharge chute 403. The punched brush is fixed by inserting the feeding head 501 and the second positioning rod 502. The position is adjusted by the sixth linear drive 504 and the seventh linear drive 505. After the brush is sent to the top of the positioning fixture, the fifth linear drive 503 drives the second positioning rod 502 to move upwards, which can remove the brush from the bottom of the second positioning rod 502 and place it on the positioning fixture.
