Description

Technical Field

[0001] This utility model relates to the field of insertion machine technology, specifically to an insertion head for a horizontal insertion machine. Background Technology

[0002] In the electronics manufacturing industry, component insertion machines are widely used to automatically insert various components into circuit boards. Traditional insertion machines typically use cylinders or hydraulic cylinders to drive the insertion head to perform the clamping and releasing operations on the components. These insertion heads usually generate linear motion through cylinders or hydraulic cylinders to push or pull the clamps to open and close, thereby achieving the clamping and releasing of components. However, with the continuous increase in production line speed, traditional cylinder-driven insertion heads have gradually revealed some undeniable shortcomings.

[0003] Pneumatic and hydraulic cylinders have relatively slow response times, especially in high-frequency, high-speed insertion operations, making them unable to meet the requirements for rapid clamping and release. Their linear motion results in a lack of sufficient flexibility and control precision throughout the clamping process, easily leading to problems such as unstable clamping and positional deviation, which in turn affects the accurate insertion of components.

[0004] Secondly, traditional pneumatic or hydraulic cylinder systems are complex in structure and have high maintenance costs. Pneumatic or hydraulic cylinder devices require corresponding air sources or hydraulic pumps, which not only increases the system's size and complexity but also necessitates strict control over the stability of the air or hydraulic system. If the air source or hydraulic system malfunctions, the insertion head will directly fail to function properly, affecting the normal operation of the entire production line. During the clamping and releasing process, the insertion head driven by pneumatic and hydraulic cylinders is easily affected by external environmental factors, such as air pressure fluctuations or hydraulic oil temperature changes. These factors can lead to instability in the clamping force, thus affecting the reliability and consistency of the insertion operation. Especially in the high-precision insertion process of electronic components, even slight changes in clamping force can cause component damage or insertion failure, reducing production efficiency and product qualification rate.

[0005] To address these issues, some insertion machines have recently begun to experiment with using motor-driven systems to replace traditional pneumatic or hydraulic cylinder systems. Motor-driven insertion heads can achieve higher control precision and response speed. However, existing motor-driven systems also face challenges such as complex structure and high cost, thus leaving room for further improvement. Utility Model Content

[0006] This utility model aims to solve the technical problems existing in the prior art or related technologies, especially the problems of slow response speed, low control accuracy and high maintenance cost of plug heads driven by traditional cylinders or hydraulic cylinders in clamping and releasing operations.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a plugging head for a horizontal plugging machine, comprising a fixed clamping seat, a drive motor, and a moving seat. A guide cylinder is fixedly installed on the surface of the fixed clamping seat, and a guide sleeve plate is fixedly installed on the inner side of the guide cylinder. The drive motor includes a transmission box, a crank block, and a push rod that is slidably sleeved on the inner side of the guide sleeve plate. A return spring located inside the guide cylinder and abutting against the top surface of the guide sleeve plate is sleeved on the surface of the push rod. The crank block is fixedly installed at the output end of the drive motor, and the surface of the crank block slidably abuts against the top end of the push rod. The bottom end of the push rod is fixedly fixed to the top surface of the moving seat. A clamping finger is rotatably installed at the bottom end of the fixed clamping seat, and a flexible clamp is fixedly installed on the surface of the clamping finger. A connecting rod that is movably connected to the surface of the clamping finger is provided at the bottom end of the moving seat.

[0008] In a preferred embodiment, this invention can be further configured such that: the surface of the crank block is provided with a pusher offset from the axis of the drive motor; both sides of the crank block are respectively provided with a pushing surface and a return surface; the outer periphery of the crank block slides against the top end of the push rod through the pusher, the pushing surface, and the return surface. By adopting the above technical solution, the crank block can realize the reciprocating motion of the push rod under the action of the drive motor, thereby controlling the clamping fingers to perform precise clamping and releasing operations, improving the response speed and control accuracy of the insert head.

[0009] In a preferred embodiment, this invention can be further configured such that both the pushing surface and the return surface are arc-shaped, with the pushing surface being a convex arc surface and the return surface being a concave arc surface. By adopting the above technical solution and utilizing the special arc surface structure on the crank block, stable movement of the push rod is achieved. In particular, the return surface design accelerates the return speed of the push rod, thereby further improving the release efficiency of the insert head.

[0010] In a preferred embodiment, this invention can be further configured such that: the motion seat is slidably mounted on the inner side of the guide cylinder and located below the guide sleeve plate, and the bottom end of the motion seat slidably passes through the fixed clamping seat and is rotatably connected to the top end of the connecting rod. By adopting the above technical solution, the sliding connection between the motion seat and the guide cylinder ensures the smoothness and consistency of the movement, thereby guaranteeing the accurate clamping and release of the finger.

[0011] In a preferred embodiment, this invention can be further configured such that the clamping fingers have an L-shaped structure, and the connection points between the clamping fingers and the connecting rod and the flexible clamp are located on both sides of the connection point between the clamping fingers and the fixed clamping seat. By adopting the above technical solution, the clamping fingers can achieve efficient clamping operations within a small structural space, and the reasonable arrangement of connection points enhances the mechanical stability of the clamping fingers, thereby improving the working reliability and durability of the plug-in head.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] 1. In this invention, a drive motor continuously and cyclically drives the crank block to rotate, and the reciprocating motion of the push rod is achieved by the contact motion between the crank block and the push rod. This motion mechanism can continuously and intermittently control the gripping and releasing operations of the clamping fingers, adapting to the feeding rhythm of the horizontal insertion machine, thereby realizing automated insertion work and greatly improving work efficiency and automation.

[0014] 2. This utility model employs a specially designed crank block structure, in which the push head and the push surfaces and return surfaces on both sides abut against the push rod. This structure achieves stable reciprocating motion of the push rod and the moving seat. In particular, the concave design of the return surface allows the push rod to retract quickly, significantly improving the efficiency of the insertion head during the release phase, further enhancing the overall operating speed and production efficiency. It can be highly matched with the feeding rhythm of a horizontal insertion machine. Through continuous cyclic drive of the motor, the insertion head can precisely control the clamping and releasing actions of the grippers, adapting to the needs of high-speed, continuous component insertion. This design is particularly suitable for large-volume, high-frequency automated production in the electronics manufacturing industry, effectively improving the overall operating efficiency of the production line and the processing quality of the products.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0026] The following is in conjunction with the appendix Figures 1-5 This invention describes an insertion head for a horizontal insertion machine, based on some embodiments of the present invention.

[0027] As shown in the figure, the horizontal insertion machine insertion head of this utility model includes a fixed clamp 100, a drive motor 200, a motion seat 300, and a series of components that cooperate with it.

[0028] The fixed clamp 100 is the main structure of the insertion head, used to support and fix other components. A guide cylinder 110 is fixedly mounted on the surface of the fixed clamp 100, and a guide sleeve plate 111 is provided on the inner side of the guide cylinder 110. The guide sleeve plate 111 is used to guide the up and down sliding of the push rod 230. A clamping finger 120 is rotatably mounted on the bottom end of the fixed clamp 100. The clamping finger 120 has an L-shaped structure, and a flexible chuck 121 is fixedly mounted on its surface. The flexible chuck 121 is used to flexibly clamp the component to prevent damage to the component.

[0029] The drive motor 200 is used to drive the various components of the insertion head to move. The drive motor 200 includes a transmission housing 210 and a crank block 220 mounted on the transmission housing 210. The surface of the crank block 220 is provided with a pusher 221 offset from the axis of the drive motor 200, and the two sides of the crank block 220 are respectively provided with a pushing surface 222 and a return surface 223. The outer periphery of the crank block 220 slides against the top end of the push rod 230 through the pusher 221, the pushing surface 222, and the return surface 223.

[0030] The push rod 230 is slidably sleeved on the inner side of the guide sleeve plate 111, and a return spring 231 is sleeved on its surface, located inside the guide cylinder 110 and abutting against the top surface of the guide sleeve plate 111. Under the action of the drive motor 200, the push rod 230 reciprocates under the guidance of the crank block 220 and the inner side of the guide cylinder 110. The bottom end of the push rod 230 is fixed to the top surface of the motion seat 300. When the push rod 230 moves, it drives the motion seat 300 to slide up and down.

[0031] The motion seat 300 is slidably mounted on the inner side of the guide tube 110, located below the guide sleeve plate 111. The bottom end of the motion seat 300 slides through the fixed clamp seat 100 and is rotatably connected to the top end of the connecting rod 122. The up and down movement of the motion seat 300 drives the clamping finger 120 to complete the clamping and releasing actions; the connecting rod 122 is a flexible silicone material component.

[0032] When the drive motor 200 starts, the transmission box 210 drives the crank block 220 to rotate continuously. Due to the sliding contact between the push head 221, the push surface 222, and the return surface 223 of the crank block 220 and the top end of the push rod 230, the push rod 230 reciprocates under the drive of the crank block 220. The reciprocating motion of the push rod 230 is transmitted to the gripper finger 120 through the motion seat 300, thereby controlling the gripper finger 120 to perform gripping and releasing operations.

[0033] During the rotation of the crank block 220, when the push surface 222 acts on the push rod 230, the push rod 230 pushes the motion seat 300 downward, and the clamping finger 120 closes and clamps the element; when the return surface 223 acts on the push rod 230, the push rod 230 quickly retracts under the action of the return spring 231, the motion seat 300 moves upward, and the clamping finger 120 opens to release the element.

[0034] Through the above structural design, the horizontal insertion machine insertion head of this utility model can achieve fast and precise clamping and release operations, adapting to the high-speed production requirements of the insertion machine and significantly improving production efficiency and operational stability. Meanwhile, the special crank block 220 structural design accelerates the retraction speed of the push rod 230, thereby further improving the efficiency of component release.

[0035] Working principle and usage process of this utility model:

[0036] The horizontal insertion machine of this invention uses a motor-driven insertion head to clamp and release components. Its working principle is as follows:

[0037] After the drive motor 200 starts, it drives the crank block 220 to rotate continuously along the fixed axis. The push head 221, the push surface 222 and the return guide surface 223 of the crank block 220 slide and abut against the top end of the push rod 230 respectively. Through the rotational motion of the crank block, the circular motion is converted into the up and down linear reciprocating motion of the push rod.

[0038] The reciprocating motion of the push rod 230 directly drives the motion seat 300 to slide up and down inside the fixed clamp 100. The sliding of the motion seat causes the clamping fingers 120 to close or open, thereby realizing the function of clamping or releasing the component.

[0039] When the pushing surface 222 of the crank block 220 abuts against the push rod 230, the push rod moves downward, the moving seat moves downward, and the clamping fingers close to hold the component; when the return guide surface 223 acts on the push rod, the push rod moves upward rapidly under the action of the return spring 231, the moving seat moves upward, the clamping fingers open, and the component is released. Through this design, this utility model can adapt to the high-speed feeding rhythm of a horizontal insertion machine and achieve continuous and precise automated operation.

[0040] Usage process

[0041] The usage process of this utility model is as follows:

[0042] Install the insertion head of the horizontal insertion machine onto the workbench of the equipment and connect the power supply and control system. Ensure that the fixed clamp 100, drive motor 200, moving seat 300, and related connecting parts such as clamping fingers 120 and push rod 230 are correctly installed.

[0043] According to production needs, the drive motor 200 is started. The drive motor starts to rotate, driving the crank block 220 to rotate continuously, thereby driving the push rod 230 and the motion seat 300 to move up and down according to the set rhythm.

[0044] After the component is prepared, the push surface 222 of the crank block acts on the push rod, the push rod moves down, driving the motion seat 300 and the gripper 120 to move down together, and the gripper begins to close and clamp the component.

[0045] After the insertion head moves the clamped component to the designated position, the equipment control system performs precise positioning and insertion operations. The clamped component is inserted into the predetermined hole on the circuit board by the clamping fingers.

[0046] Once the component is inserted into place, the return surface 223 of the crank block acts on the push rod, causing the push rod to move upward. The clamping fingers 120 open under the action of the motion seat 300, thereby releasing the component. The push rod quickly returns to its initial position under the action of the return spring 231, ready for the next clamping operation.

[0047] The drive motor continues to rotate, and the insertion head continues to perform clamping and releasing operations according to the above process until the insertion of all components is completed.

[0048] After all components are installed, turn off the drive motor and shut down the equipment. According to the maintenance plan, inspect and maintain all components of the insertion head, such as the clamping fingers, push rods, and crank blocks, to ensure the equipment's reliability for the next use.
