In the existing technology, the SMT placement machines on the current market generally have the problems of large size and high price. For small and micro enterprises with relatively single products, high investment in SMT placement machines often means that their cash flow will be affected to a considerable extent. The technology of high-end SMT placement machines is updated rapidly. For small and micro enterprises with limited funds, frequent technology follow-up and equipment upgrades are almost unbearable. Small and micro enterprises often need to respond quickly to market changes and adjust production plans, but large and expensive SMT placement machines lack flexibility and are not suitable for frequent replacement of production lines or small-batch production, which limits the market response speed and product innovation capabilities of small and micro enterprises. To address this problem, the utility model solves it by installing rail columns. When the staff needs to place the components, the starting motor is started to drive the bottom bevel gear to engage the flat double-headed bevel gear to rotate, causing the rail column to rotate. At the same time, the circular end of the groove slides in the cam groove on its circumference. When the circular end of the groove slides from the upper end to the lower end of the cam groove, the circular end of the groove drives the torque member, the large diameter end and the placement column to move downward. The lifting spring is compressed to accumulate elastic potential energy for placement. When the placement is completed, the circular end of the groove is The lower end of the cam slide enters the vertical groove. After entering the vertical groove, the circular end of the groove loses its restraint, and the lifting spring releases elastic potential energy, causing the circular end of the groove to quickly rise. The rail column continuously rotates, causing the mounting column to reciprocate up and down for rapid mounting. In this way, when the mounting column moves downward, the lifting spring is compressed, causing the mounting column to gradually slow down when it is about to reach the mounting position to prevent collision with the mounting material. At the same time, this structure greatly reduces the temporary space of the stroke component and only requires a single motor for driving, avoiding the use of a large number of drive motors and linear motors, reducing production costs, achieving miniaturization and lightweight, and facilitating control and installation by staff. For small and micro enterprises with a single or small number of product types, it enables them to enter the SMT mounting machine related market.Achieve the effect of reducing production costs and increasing the scope of application of equipment.

[0006] Preferably, the groove depth of the top and bottom ends of the vertical groove is greater than the groove depth of the middle end of the vertical groove, a positioning spring is fixed to the inner wall of the moment-fixing member, one end of the positioning spring is fixed to a spring-bearing disk, the side surface of the spring-bearing disk is slidably connected to the inner wall of the moment-fixing member, and one end of the spring-bearing disk is fixed to a groove-running round end. In the prior art, when the groove-running round end enters the vertical groove, the rise of the groove-running round end in the vertical groove is driven by the elastic potential energy released by the lifting spring, which is easy to cause the groove-running round end to collide with the top end of the vertical groove and directly enter the cam slide groove due to the rapid release of the elastic potential energy. As a result, the mounting column shakes rapidly after rising, affecting To improve the stability of the components, the present invention adopts the method of installing a positioning spring to solve such problems. When the circular end of the groove reaches the top or bottom of the vertical groove, the depth of the cam slide groove is the same as the groove depth at the middle end of the vertical groove, and both are smaller than the groove depth at the top and bottom ends of the vertical groove. The contact between grooves of different depths is provided with an inclined surface to facilitate the sliding of the circular end of the groove in the groove. The positioning spring releases elastic potential energy to push the spring-bearing plate to make the circular end of the groove pop out and embed into the top or bottom end of the deeper vertical groove, so that the mounting column can remain stable when rising or falling to the extreme, thereby achieving the effect of improving the stability of the component and improving the yield rate.

[0007] Preferably, an auxiliary ladder groove is provided on the inner wall of the rectangular frame, and a ladder member is slidably connected to the inner wall of the auxiliary ladder groove. One end of the ladder member is fixed to the circumference of the large-diameter end head.

[0012] Beneficial effects:

[0013] 1. In the existing technology, the SMT placement machines on the current market generally have the problems of being large in size and high in price. For small and micro enterprises with relatively single products, high investment in SMT placement machines often means that their cash flow will be affected to a considerable extent. The technology of high-end SMT placement machines is updated rapidly. For small and micro enterprises with limited funds, frequent technology follow-up and equipment upgrades are almost unaffordable. Small and micro enterprises often need to respond quickly to market changes and adjust production plans, but large and expensive SMT placement machines lack flexibility and are not suitable for frequent replacement of production lines or small-batch production, which limits the market response speed and product innovation capabilities of small and micro enterprises. In response to such problems, the utility model solves the problem by installing rail columns, so that when the staff needs to place the components, the starting motor is started to drive the bottom bevel gear to engage the flat double-headed bevel gear to rotate, causing the rail column to rotate, and at the same time, the circular end of the groove slides in the cam groove on its circumference. When the circular end of the groove slides from the upper end to the lower end of the cam groove When the guide rail is in motion, the circular end of the groove drives the moment fixing member, the large diameter end and the mounting column to move downward, and the lifting spring is compressed to accumulate elastic potential energy for mounting. At the same time as the mounting is completed, the circular end of the groove enters the vertical groove from the lower end of the cam slide. After entering the vertical groove, the circular end of the groove loses its constraint, and the lifting spring releases its elastic potential energy, causing the circular end of the groove to quickly recover. Through the continuous rotation of the rail column, the mounting column is made to reciprocate up and down for rapid mounting. In this way, when the mounting column moves downward, due to the pressure of the lifting spring, the mounting column gradually slows down when it is about to reach the mounting position to prevent it from hitting the mounting material. At the same time, this structure greatly reduces the temporary space of the stroke component and only requires a single motor for driving, avoiding the use of a large number of drive motors and linear motors, reducing production costs, achieving miniaturization and lightweight, and being easy for staff to control and install. For small and micro enterprises with a single or few product types, it enables them to enter the SMT mounting machine related market, thereby reducing production costs and increasing the scope of application of the equipment.

[0014] When the cam is in the groove, the spring is released, and the spring is released to push the cam plate to release the elastic potential energy of the cam plate, so that the cam plate will not move.

[0015] 3. By matching the ladder parts and the auxiliary ladder grooves to improve the stability of the components during operation, the reduction in yield caused by component shaking can be avoided, the stability of the equipment can be improved, and the yield can be increased. The staff can provide replacement of blocking plates of different heights and rail posts of different tracks to adapt to different products and improve the applicability of the equipment.

[0025] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

The SMT placement machines on the current market generally have the problems of being too large in size and too high in price. For small and micro enterprises with relatively single products, high investment in SMT placement machines often means that their cash flow will be affected to a considerable extent. High-end SMT placement machines The technology is updated rapidly. For small and micro enterprises with limited funds, frequent technology follow-up and equipment replacement are almost unaffordable. Small and micro enterprises often need to respond quickly to market changes and adjust production plans, but large and expensive SMT placement machines lack flexibility and are not suitable for frequent replacement of production lines or small-batch production. This limits the market response speed and product innovation capabilities of small and micro enterprises. The solution is to install the rail column 205. When the staff needs to place the mount, the starting motor 202 is started to drive the bottom bevel gear 203 to engage the flat double-headed bevel gear 204 to rotate, so that the rail column 205 rotates. At the same time, the groove circle end 2013 slides in the cam groove 206 on its circumference. When the groove circle end 2013 moves from the upper end to the lower end of the cam groove 206 During sliding, the circular end 2013 of the groove drives the moment fixing member 2012, the large diameter end 209 and the mounting column 2010 to move downward, and the lifting spring 2011 is compressed to accumulate elastic potential energy for mounting. At the same time as the mounting is completed, the circular end 2013 of the groove enters the vertical groove 207 from the lower end of the cam slide 206. After entering the vertical groove 207, the circular end 2013 of the groove loses its constraint, and the lifting spring 2011 releases its elastic potential energy, causing the circular end 2013 to quickly rise up, and the rail column 205 continuously rotates, causing the mounting column 2010 to reciprocate up and down for rapid mounting. In this way, when the mounting column 2010 moves downward, due to the pressure of the lifting spring 2011, the mounting column 2010 gradually slows down when it is about to reach the mounting position, thereby preventing it from hitting the mounting material.At the same time, this structure greatly reduces the temporary space required for travel components and only requires a single motor for drive, avoiding the use of a large number of drive motors and linear motors, reducing production costs, achieving miniaturization and lightweighting, and making it easier for workers to control and install. For small and micro enterprises with a single or limited product range, it enables them to enter the SMT placement machine market, achieving the effect of reducing production costs and expanding the scope of application of equipment.

[0028] The groove depth of the top end and the bottom end of the vertical groove 207 is greater than the groove depth of the middle end of the vertical groove 207. A positioning spring 3 is fixed to the inner wall of the moment fixing member 2012. A spring plate 301 is fixed to one end of the positioning spring 3. The side of the spring plate 301 is slidably connected to the inner wall of the moment fixing member 2012. A groove circular end 2013 is fixed to one end of the spring plate 301. When the groove circular end 2013 enters the vertical groove 207, the groove circular end 2013 rises in the vertical groove 207 due to the elastic potential energy released by the lifting spring 211. It is easy to cause the groove circular end 2013 to collide with the top end of the vertical groove 207 and directly enter the cam slide groove 206 due to the rapid release of the elastic potential energy, causing the mounting column 2010 to rise. After that, it shakes rapidly, affecting the stability of the component. This problem is solved by installing a positioning spring 3. When the groove circle end 2013 reaches the top or bottom of the vertical groove 207, the groove depth of the cam slide 206 is the same as the groove depth at the middle end of the vertical groove 207, and both are smaller than the groove depths at the top and bottom ends of the vertical groove 207. The contact between grooves of different depths is provided with an inclined surface to facilitate the sliding of the groove circle end 2013 in the groove. The positioning spring 3 releases its elastic potential energy to push the spring plate 301 to make the groove circle end 2013 pop out and embed into the top or bottom end of the deeper vertical groove 207, so that the mounting column 2010 can remain stable when rising or falling to the extreme, thereby achieving the effect of improving the stability of the component and improving the yield rate. An auxiliary ladder groove 4 is provided on the inner wall of the rectangular frame 208. A ladder member 401 is slidably connected to the inner wall of the auxiliary ladder groove 4. One end of the ladder member 401 is fixed to the circumference of the large-diameter end 209. The coordination between the ladder member 401 and the auxiliary ladder groove 4 improves the stability of the component during operation, avoids the reduction in yield caused by component shaking, improves the stability of the equipment, and increases the yield. A lifting pad 5 is fixed on the top of the inner wall of the rectangular frame 208 to prevent collisions between components and increase the service life of the equipment. A blocking plate 501 is fixed on the bottom of the inner wall of the rectangular frame 208. The staff can provide replacement blocking plates 501 of different heights and rail posts 205 of different tracks to adapt to different products and increase the scope of application of the equipment. Side stabilizers 6 are fixed on both sides of the equipment body 1 to improve the stability of the equipment. A hand-held slot 601 is provided on one side of the side stabilizer 6 to facilitate staff transportation and improve user experience.

[0029] The working principle of the present invention is as follows: when the staff needs to perform mounting, the starting motor 202 is started to drive the bottom vertical bevel gear 203 to engage the flat double-headed bevel gear 204 to rotate, so that the rail column 205 rotates, and at the same time, the groove circular end 2013 slides in the cam groove 206 on its circumference. When the groove circular end 2013 slides from the upper end to the lower end of the cam groove 206, the groove circular end 2013 drives the moment fixing member 2012, the large diameter end 209 and the mounting column 2010 to move downward, and the lifting spring 2011 is compressed to accumulate elastic potential energy for mounting. When the mounting is completed, the groove circular end 2013 enters the vertical groove 207 from the lower end of the cam groove 206. After entering the vertical groove 207, the groove circular end 2013 loses its constraint, and the lifting spring 20 11 releases elastic potential energy, causing the circular end 2013 of the groove to rebound quickly, and the rail column 205 rotates continuously, causing the mounting column 2010 to move up and down quickly for mounting. In this way, when the mounting column 2010 moves downward, the lifting spring 2011 is compressed, causing the mounting column 2010 to gradually slow down when it is about to reach the mounting position to prevent collision with the mounting material. At the same time, this structure greatly reduces the temporary space of the stroke component and only requires a single motor for driving, avoiding the use of a large number of drive motors and linear motors, reducing production costs, achieving miniaturization and lightweight, and facilitating control and installation by staff. For small and micro enterprises with a single or fewer product types, this enables them to enter the SMT mounting machine-related market.
