Description

Technical Field

[0001] This utility model relates to the technical field of brake structures, specifically to a brake mechanism for a feeding mechanism. Background Technology

[0002] When assembling relays automatically, the first step is to achieve automated feeding of tray-mounted relays. When the tray is sent to the waiting area by the conveyor belt, the tray needs to stop on the conveyor belt, and the stopping position is located in the waiting area.

[0003] Currently, the structure for controlling the stopping of the conveyor belt involves bringing the feed tray into contact with the conveyor belt when a stop is required. The friction between the feed tray and the conveyor belt causes the feed tray to stop moving. However, due to inertia, the stopping position of the feed tray deviates slightly from the required position, affecting the production of the next process. Utility Model Content

[0004] The technical problem this invention aims to solve is that current methods rely on friction between the feeding disc and the conveyor belt to stop the feeding disc, resulting in inaccurate stopping positions. The purpose is to provide a braking mechanism for the feeding mechanism that, when braking is needed, causes the drive mechanism to slide away from the braking structure, thereby disengaging the limiting block from the brake block. The elastic element then resets, and the top of the elastic element moves downward, pulling the brake block down to restrict the rotation of the driven gear. This eliminates the influence of inertial force on the movement of the feeding disc, thereby improving the accuracy of the feeding block's stopping position and ensuring normal production in the next process.

[0005] This utility model is achieved through the following technical solution:

[0006] A braking mechanism for a feeding mechanism includes a drive mechanism and a braking structure. The drive mechanism is slidably mounted on a base plate, and a limit block is connected to the top of the drive mechanism. The braking structure includes an elastic element and a brake block. The bottom of the elastic element is connected to a brake mounting plate, and the top of the elastic element is connected to the brake block. The top of the brake block can slide along the top of the limit block. When the feeding tray needs to stop, the drive mechanism slides towards the end away from the braking structure, and the elastic element pulls the brake block down to restrict the rotation of the driven gear.

[0007] The beneficial effects of this utility model are as follows: by setting a limiting block at the top of the drive mechanism and allowing the top of the brake block to slide in cooperation, and by connecting the bottom of the brake block to the elastic element, it is convenient to ensure that when braking is not required, the top of the brake block is located at the top of the limiting block, allowing the brake block to move upward, and the drive mechanism to transmit kinetic energy to the driven gear, so that the feeding tray moves normally; when braking is required, the drive mechanism slides towards the end away from the brake structure, thereby causing the limiting block to disengage from the brake block, improving the accuracy of the stopping position of the feeding tray during braking, and under the action of the restoring force of the elastic element, the top of the elastic element moves downward, pulling down the brake block to restrict the rotation of the driven gear, eliminating the influence of inertial force on the movement of the feeding tray, further improving the accuracy of the stopping position of the feeding block, and ensuring normal production in the next process.

[0008] In some embodiments, the driving mechanism includes a drive motor and a support plate. The support plate is L-shaped and slidably mounted on the base plate. The drive motor is mounted on the horizontal portion of the support plate. The output shaft of the drive motor extends out of the vertical portion of the support plate and is fitted with a first pulley. A transmission shaft is also mounted on the vertical portion of the support plate. A second pulley is mounted at one end of the transmission shaft, and a drive gear is mounted at the other end. The first pulley and the second pulley are driven by a belt. By mounting the motor, the first pulley, and the second pulley on the support plate, and transmitting the motor's output torque to the drive gear via the pulleys, and by slidably connecting the support plate to the base plate so that the drive gear slides when the support plate slides, the meshing state between the drive gear and the driven gear can be disengaged, thereby improving the accuracy of the material tray's stopping position during braking.

[0009] In some embodiments, a material tray drive shaft is mounted on the brake mounting plate, and a driven gear is mounted on the material tray drive shaft. The driven gear is meshed with the driving gear. In a working state where the material tray needs to be stopped, the drive mechanism slides towards the end away from the brake structure, and the driven gear disengages from the driving gear. By disengaging the driven gear from the driving gear, the movement of the material tray is stopped.

[0010] In some embodiments, a guide rail is mounted on the base plate, and a slider is mounted on the bottom of the support plate, the slider being slidably connected to the guide rail. By mounting the guide rail on the base plate and engaging the slider, the support plate is guided as it moves.

[0011] In some embodiments, a cylinder is mounted on the end of the base plate away from the support plate, and the free end of the piston rod of the cylinder is connected to the horizontal portion of the support plate. By connecting the piston rod of the cylinder to the horizontal portion of the support plate, it is convenient to move the support plate by means of the cylinder, thereby enabling the drive mechanism to move.

[0012] In some embodiments, a pulley is mounted on the end of the feed tray drive shaft away from the driven gear. The pulley engages with a belt mounted on the bottom of the feed tray to drive the feed tray. By mounting a pulley on the end of the feed tray drive shaft away from the driven gear, the feed tray stops moving when the feed tray drive shaft stops rotating, thereby controlling the stop position of the feed tray.

[0013] In some embodiments, the bottom of the elastic member is connected to the brake mounting plate by screws, and the top of the elastic member is connected to the top of the brake block by screws. The top of the brake block is provided with a contact portion, which can slide along the limiting block. By contacting the limiting block with the contact portion, the brake block is raised so as not to contact the driven gear. When the contact portion slides away from the limiting block, it moves downward under the action of the elastic member to contact the driven gear, thus restricting the rotation of the driven gear.

[0014] In some embodiments, the top of the limiting block is provided with an inclined portion, which slopes downward from the top of the limiting block to the side of the limiting block away from the cylinder, and the contact portion can slide along the inclined portion. By providing an inclined portion at the top of the limiting block to guide the contact portion, the contact portion can enter the limiting block from the lower end of the inclined portion and move upward along the inclined portion, causing the brake block to gradually rise. When the drive mechanism slides towards the end away from the brake block, the contact portion slides from the upper end to the lower end of the inclined portion and disengages, thereby achieving braking.

[0015] In some embodiments, the contact portion is located on the side away from the elastic member and is cylindrical in shape, and the outer periphery of the contact portion can slide along the inclined portion. By setting the contact portion to be cylindrical, the outer periphery of the cylinder slides in contact with the inclined portion, reducing the contact area between the contact portion and the inclined portion, thereby reducing the frictional force during sliding.

[0016] In some embodiments, the bottom of the brake block is provided with at least two protruding teeth, which may be located within the tooth groove of the driven gear. By providing protruding teeth at the bottom of the brake block to engage with the tooth groove of the driven gear, the contact area between the brake block and the driven gear is increased during braking, thereby improving the braking effect.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. During braking, the drive mechanism slides towards the end away from the brake structure, the limit block disengages from the brake block, and the elastic element resets, pulling the brake block down into the tooth groove of the driven gear. This eliminates the influence of inertial force on the movement of the conveyor plate, thereby improving the accuracy of the stopping position of the conveyor block and ensuring normal production in the next process.

[0019] 2. By connecting the piston rod of the cylinder to the horizontal part of the support plate, it is easy to move the support plate through the cylinder, thereby driving the drive mechanism to move.

[0020] 3. The contact part is made cylindrical, so that the outer periphery of the cylinder slides in contact with the inclined part, thereby reducing the contact area between the contact part and the inclined part and reducing the friction during sliding. Attached Figure Description

[0032] Example

[0033] like Figures 1-4As shown, this embodiment provides a braking mechanism for a feeding mechanism, including a drive mechanism and a braking structure. The drive mechanism is slidably mounted on a base plate 10, and a limit block 13 is connected to the top of the drive mechanism. The braking structure includes an elastic element 25 and a brake block. The bottom of the elastic element 25 is connected to a brake mounting plate 12, and the top is connected to the brake block. The top of the brake block can slide along the top of the limit block 13. When the feeding tray needs to stop, the drive mechanism slides towards the end away from the braking structure, and the elastic element 25 pulls down the brake block to restrict the rotation of the driven gear 18. When braking is required, the drive mechanism slides towards the end away from the braking structure, thereby causing the limit block 13 to disengage from the brake block, improving the accuracy of the feeding tray's stopping position during braking. Under the action of the restoring force of the elastic element 25, the top of the elastic element 25 moves down, pulling down the brake block to restrict the rotation of the driven gear 18, eliminating the influence of inertial force on the movement of the feeding tray, further improving the accuracy of the feeding tray's stopping position, and ensuring normal production in the next process.

[0034] Specifically, the elastic element 25 in this utility model can be a tension spring, spring, rubber spring, gas spring, etc.

[0035] like Figures 1-4 As shown, the driving mechanism includes a drive motor 19 and a support plate 14. The support plate 14 is L-shaped and slidably mounted on the base plate 10. The drive motor 19 is mounted on the horizontal part of the support plate 14. The output shaft of the drive motor 19 extends out of the vertical part of the support plate 14 and is fitted with a first pulley 15. A transmission shaft is also mounted on the vertical part of the support plate 14. A second pulley 16 is mounted on one end of the transmission shaft, and a drive gear 17 is mounted on the other end. The first pulley 15 and the second pulley 16 are driven by a belt. By mounting the motor, the first pulley 15, and the second pulley 16 on the support plate 14, and transmitting the motor's output torque to the drive gear 17 via the pulleys, and by slidably connecting the support plate 14 to the base plate 10, the drive gear 17 can be moved when the support plate 14 slides. This disengages the drive gear 17 from the driven gear 18, improving the accuracy of the material tray's stopping position during braking.

[0036] like Figures 1-4 As shown, a material tray drive shaft is mounted on the brake mounting plate 12. The driven gear 18 is mounted on the material tray drive shaft, and the driven gear 18 can mesh with the driving gear 17. In the working state where the material tray needs to be stopped, the drive mechanism slides towards the end away from the brake structure, and the driven gear 18 disengages from the driving gear 17. By disengaging the driven gear 18 from the driving gear 17, the movement of the material tray is stopped.

[0037] like Figures 1-4 As shown, a guide rail 21 is mounted on the base plate 10, and a slider is mounted on the bottom of the support plate 14. The slider is slidably connected to the guide rail 21. By mounting the guide rail 21 on the base plate 10 and cooperating with the slider, the support plate 14 is guided by the guide rail 21 when it moves.

[0038] like Figures 1-4 As shown, a cylinder 20 is mounted on the end of the base plate 10 away from the support plate 14, and the free end of the piston rod of the cylinder 20 is connected to the horizontal part of the support plate 14. By connecting the piston rod of the cylinder 20 to the horizontal part of the support plate 14, it is convenient to drive the support plate 14 to move through the cylinder 20, thereby driving the drive mechanism to move.

[0039] like Figures 1-4 As shown, a pulley is mounted on the end of the material tray drive shaft away from the driven gear 18. The pulley engages with a belt mounted on the bottom of the feeding tray 22 to drive the feeding tray 22. By mounting a pulley on the end of the material tray drive shaft away from the driven gear 18, the feeding tray 22 can be stopped moving when the material tray drive shaft stops rotating, thereby controlling the stop position of the feeding tray 22.

[0040] like Figures 1-4 As shown, the bottom of the elastic member 25 is connected to the brake mounting plate 12 by screws, and the top of the elastic member 25 is connected to the top of the brake block by screws. The top of the brake block is provided with a contact portion 241, which can slide along the limiting block 13. By contacting the limiting block 13 with the contact portion 241, the brake block is raised and does not contact the driven gear 18. When the contact portion 241 slides away from the limiting block 13, it moves down under the action of the elastic member 25 and contacts the driven gear, thus restricting the rotation of the driven gear.

[0041] like Figures 1-4 As shown, the top of the limiting block 13 is provided with an inclined portion, which slopes downward from the top of the limiting block 13 to the side of the limiting block 13 away from the cylinder 20. The contact portion 241 can slide along the inclined portion. By providing an inclined portion at the top of the limiting block 13 to guide the contact portion 241, the contact portion 241 can enter the limiting block 13 from the lower end of the inclined portion and move upward along the inclined portion, causing the brake block to gradually rise. When the drive mechanism slides towards the end away from the brake block, the contact portion 241 slides from the upper end to the lower end of the inclined portion and disengages, thus achieving braking.

[0042] See Figure 4The contact portion 241 is located on the side away from the elastic member 25 and is cylindrical in shape. The outer periphery of the contact portion 241 can slide along the inclined portion. By setting the contact portion 241 to be cylindrical, the outer periphery of the cylinder slides in contact with the inclined portion, reducing the contact area between the contact portion 241 and the inclined portion, thereby reducing the friction during sliding.

[0043] See Figure 4 The brake block has at least two protruding teeth at its bottom, which can be located within the tooth groove of the driven gear 18. By providing protruding teeth at the bottom of the brake block to engage with the tooth groove of the driven gear, the contact area between the brake block and the driven gear is increased during braking, thereby improving the braking effect.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
