Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip mounter technology, specifically to an electric feeder chip mounter device. Background Technology
[0002] In SMT production lines, the electric feeder, as a core component for precise component feeding, needs to be stably assembled and positioned with the placement machine's mounting base to ensure the accuracy and efficiency of subsequent placement operations. Currently, the industry standard for assembling and positioning electric feeders and mounting bases generally involves designing a guide rail structure at the bottom of the feeder. During assembly, the guide rail and mounting base work together to achieve initial alignment, and then a specialized locking mechanism is used to fix the guide rail in place, thus completing the feeder installation and ensuring that it does not shift position during high-speed operation.
[0003] In most common electric feeder mounting base designs, there is no double-sided coordinating guide structure for the feeder guide rail. Operators often rely on manually aligning the bottom guide rail of the feeder with the mounting area of the mounting base, or only a simple guide protrusion is set on one side of the mounting base. This results in repeated adjustments to the feeder angle and position to achieve guide rail alignment during assembly, significantly extending the assembly operation time. At the same time, existing locking mechanisms often use a single-sided clamping design, or fix the guide rails on both sides separately with two independent manual locking knobs. When operators operate step by step, uneven locking force on both sides can easily occur due to differences in force control. This can cause slight positioning offset after feeder assembly, which cannot meet the working requirements of the pick-and-place machine. Therefore, an electric feeder placement device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an electric feeder patching device to solve the technical problem that uneven locking force on both sides can easily occur during the assembly of an electric feeder due to differences in force control.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric feeder patch device, comprising: An assembly base, the top of which is equipped with a base plate, an electric feeder is installed on the outside of the base plate, and guide strips are connected to both sides of the upper surface of the assembly base; The guide rail is installed on the outer side of the lower surface of the base plate. The upper surface of the mounting base is connected to both sides of the mounting strip. Locking heads are inserted into both sides of the inner side of the mounting strip. The top of the locking head is hinged to the transmission link at the position inside the mounting strip. A hinged frame is sleeved on the outside of the transmission connecting rod. A screw-on sleeve is installed at the front end of the mounting base. A lead screw is screwed into the inside of the screw-on sleeve. A bearing plate is installed at the outer end of the lead screw.
[0006] Preferably, the inner side of each guide bar is provided with a limiting groove, and the outer side of each guide rail is provided with a limiting insert. The limiting groove and the limiting insert are both trapezoidal in shape. The trapezoidal limiting groove and the limiting insert cooperate to accurately guide the guide rail to be embedded during the assembly of the electric feeder, avoiding lateral deviation of the guide rail during the assembly process. At the same time, the trapezoidal structure can prevent the guide rail from falling out, further improving the stability and reliability of the assembly alignment.
[0007] Preferably, the inner side of the guide rail is provided with a slot, the size of which is adapted to the size of the locking head. The number of locking heads on one side is 2-4 sets. The guide rail slot and the matching locking head cooperate to allow the locking head to be accurately locked into the slot. Multiple sets of locking heads can distribute the clamping force, making the guide rail more evenly stressed, avoiding deformation caused by excessive local stress, and ensuring the positioning stability after clamping.
[0008] Preferably, the outer ends of the transmission links are all connected by hinge shafts, and the upper and lower outer sides of the transmission links are connected to the corresponding positions on the inner side of the hinge frame by hinge shafts. The transmission links are connected by hinge shafts and the upper and lower sides are connected to the hinge frame, which allows the transmission force to be transmitted to each link more evenly, ensuring that all transmission links move synchronously when the hinge frame moves, and avoiding the locking head movement deviation caused by the lag of transmission on one side.
[0009] Preferably, a lever is circumferentially connected to the outer end of the lead screw, and the end of the lead screw facing the bearing disc is connected to the inner ring of the bearing disc. The outer side of the bearing disc is connected to the hinge frame. The lever at the outer end of the lead screw facilitates the operator to rotate the lead screw. The bearing disc connection method can reduce the frictional resistance when the lead screw rotates, which reduces the difficulty of operation and reduces the wear of components. At the same time, the added bearing disc prevents the hinge frame from rotating synchronously when the lead screw is rotated, so that the hinge frame moves horizontally when the lead screw is rotated.
[0010] Preferably, the end of the locking head facing the guide rail is covered with an elastic wear-resistant pad. The elastic wear-resistant pad is connected to the locking head by vulcanization bonding. The elastic wear-resistant pad is made of nitrile rubber. The nitrile rubber elastic wear-resistant pad is fixed to the end of the locking head by vulcanization bonding. It can not only buffer the impact force during clamping and prevent damage to the guide rail, but also enhance the friction with the guide rail and improve the clamping stability. At the same time, the wear-resistant properties can extend the service life of the locking head.
[0011] Compared with the prior art, the present invention provides an electric feeder patch device, which has the following advantages: This electric feeder placement device uses guide rails installed on both sides of the top of the mounting base. During assembly, the electric feeder first inserts its bottom guide rails into the position between the guide rails and the mounting base. Then, by rotating the lead screw, the hinge frame and transmission linkage move, which simultaneously drives the expansion of the locking heads on both sides of the mounting base, thus clamping the guide rails. This allows for efficient and stable assembly and positioning of the electric feeder. Furthermore, because the locking heads on both sides of the mounting base expand and clamp the guide rails simultaneously, it ensures that the movements of the locking heads on both sides are consistent, avoiding positioning offset problems caused by uneven clamping force on one side. This ensures that the electric feeder is always in a precise position after assembly, reducing placement defects caused by feeder position deviation, lowering the rework frequency in the production process, ensuring continuous and stable operation of the SMT production line, and eliminating the need for frequent secondary calibration of the feeder position.

Please see Figure 1 The top of the mounting base 1 is equipped with a base plate 2, and an electric feeder 3 is mounted on the outside of the base plate 2. Please refer to [link / reference]. Figure 2Guide strips 4 are connected to both sides of the upper surface of the mounting base 1; Guide rail 5 is mounted on the outer side of the lower surface of base plate 2. Please refer to [link / reference]. Figure 3 Assembly strips 6 are connected to both sides of the upper surface of the assembly base 1. Please refer to [link / reference]. Figure 4 Locking heads 7 are inserted into both sides of the assembly strip 6. A transmission connecting rod 8 is hinged to the top of the locking head 7 at the position inside the assembly strip 6. A limit groove 14 is opened on the inner side of the guide strip 4. A limit insert 15 is installed on the outer side of the guide rail 5. The limit groove 14 and the limit insert 15 are both trapezoidal in shape. A slot 13 is opened on the inner side of the guide rail 5. The size of the slot 13 is adapted to the size of the locking head 7. The number of locking heads 7 on one side is 2-4 sets. The hinge frame 9 is sleeved on the outside of the transmission connecting rod 8. The front end of the mounting base 1 is equipped with a screw sleeve 10. The screw sleeve 10 is screwed with a lead screw 11 inside. The outer end of the lead screw 11 is equipped with a bearing plate 12. The outer ends of the transmission connecting rod 8 are all connected by hinge shafts. The upper and lower outer sides of the transmission connecting rod 8 are connected to the corresponding positions on the inner side of the hinge frame 9 through hinge shafts. By installing guide bars 4 on both sides of the top of the mounting base 1, the electric feeder 3 first inserts its bottom guide rails 5 into the position between the guide bars 4 and the mounting base 1 during assembly. Then, by rotating the lead screw 11, the hinge frame 9 and the transmission link 8 are driven to move, which can simultaneously drive the locking heads 7 on both sides of the mounting base 1 to expand outward, thereby clamping the guide rails 5. This allows for efficient and stable assembly and positioning of the electric feeder 3. Furthermore, because the locking heads 7 on both sides of the mounting base 1 expand outward to clamp the guide rails 5, the movement of the locking heads 7 on both sides is kept consistent, avoiding the positioning offset problem caused by uneven clamping force on one side. This ensures that the electric feeder 3 is always in a precise position after assembly, reducing placement defects caused by feeder position deviation, reducing the rework frequency in the production process, ensuring continuous and stable operation of the SMT production line, and eliminating the need for frequent secondary calibration of the feeder position. The outer end of the lead screw 11 is circumferentially connected to a lever. The end of the lead screw 11 facing the bearing disk 12 is connected to the inner ring of the bearing disk 12. The outer side of the bearing disk 12 is connected to the hinge frame 9. The end of the locking head 7 facing the guide rail 5 is covered with an elastic wear-resistant pad. The elastic wear-resistant pad is connected to the locking head 7 by vulcanization bonding. The elastic wear-resistant pad is made of nitrile rubber.
[0016] This solution installs guide bars 4 on both sides of the top of the mounting base 1. During assembly, the electric feeder 3 first inserts its bottom guide rails 5 into the position between the guide bars 4 and the mounting base 1. Then, by rotating the lead screw 11, the hinge frame 9 and the transmission link 8 are driven to move, which simultaneously drives the locking heads 7 on both sides of the mounting base 1 to expand outward, thereby clamping the guide rails 5. This allows for efficient and stable assembly and positioning of the electric feeder 3. Furthermore, because the locking heads 7 on both sides of the mounting base 1 expand outward to clamp the guide rails 5, the movement of the locking heads 7 on both sides is kept consistent, avoiding positioning offset problems caused by uneven clamping force on one side. This ensures that the electric feeder 3 is always in a precise position after assembly, reducing placement defects caused by feeder position deviation, reducing the rework frequency in the production process, ensuring continuous and stable operation of the SMT production line, and eliminating the need for frequent secondary calibration of the feeder position.
