Description

Technical Field

[0001] This utility model belongs to the field of feeding machine technology, specifically a clamp-type feeding machine with a protection mechanism. Background Technology

[0002] A clamp feeder is an automated device that uses mechanical grippers or clamps to hold materials (such as metal sheets, coils, and plates) and convey them along a set trajectory. It is widely used in stamping, electronics manufacturing, and automotive parts production. Its core function is to achieve precise material positioning and continuous feeding, thereby improving production efficiency and processing accuracy.

[0003] Meanwhile, the patent specification with application number CN220200522U discloses a clamping feeder with a protective mechanism, "including a conveyor belt, a protective mechanism on the top of the conveyor belt, fixed plates on both sides of the top of the conveyor belt, and a top plate on the top of the fixed plates. This clamping feeder with a protective mechanism, through the movement of the positioning plate and the ring, allows the positioning plate to be located on the top side of the material. When the ring moves, the ring is located at one end of the circular groove, allowing the bottom end of the clamping rod to approach the material, reducing the distance between the clamping rod and the material, reducing the subsequent movement distance, and facilitating clamping. Then, the use of a motor causes the cross rod to rotate."

[0004] When using existing clamping feeders, rigid clamping blocks can easily cause scratches, indentations, or even cracks on the workpiece surface when clamping irregular or fragile materials. Especially under high-speed feeding conditions, impact loads can exacerbate the damage. Furthermore, traditional fixed clamps are difficult to adapt to materials of different thicknesses or contours, requiring frequent machine stops for adjustments, resulting in low production efficiency.

[0005] Therefore, a clamp-type feeder with a protective mechanism is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a clamping feeder with a protective mechanism, which effectively avoids damage to the material surface, is suitable for non-destructive clamping of fragile workpieces such as precision electronic components and thin metal plates, and can adapt to materials of different specifications without manual intervention, shortening feeder changeover time and significantly improving production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping feeder with a protective mechanism, comprising a conveyor frame, an electric slide rail installed on the lower inner wall of the conveyor frame, a movable plate slidably connected to the outer surface of the electric slide rail, two cylinders fixedly connected to the bottom end of the movable plate, a clamping assembly fixedly connected to the output ends of the two cylinders, the clamping assembly comprising a fixed frame, the output ends of the two cylinders being fixedly connected to the fixed frame via a connecting frame, a power motor fixedly connected to the top end of the fixed frame, the output end of the power motor passing through the fixed frame and fixedly connected to a lead screw, an adjusting block threaded onto the outer surface of the lead screw, two adjusting rods rotatably connected to both ends of the adjusting block, two corresponding adjusting rods rotatably connected to clamping blocks, a crossbar fixedly connected to one corresponding end of the fixed frame, two clamping blocks slidably connected to the crossbar, and a protective assembly installed on one corresponding end of each of the two clamping blocks.

[0008] Preferably, the cross-section of the crossbar is rectangular.

[0009] Preferably, the protective component includes a buffer box, one end of which has a plurality of circular grooves arranged in a rectangular array, and the inner surface of the buffer box has a plurality of buffer slots, which are respectively connected to the plurality of circular grooves. The inner surface of each of the plurality of circular grooves is connected to a buffer rod, which passes through the plurality of circular grooves and extends into the plurality of buffer slots. One end of each of the plurality of buffer rods located in the plurality of buffer slots is fixed with a limiting plate, and one end of each of the plurality of limiting plates is fixedly connected with a spring. One end of the buffer box is fixedly connected with an elastic protective sleeve, and the plurality of buffer rods are located together within the elastic protective sleeve.

[0010] Preferably, one end of each of the springs is fixedly connected to one side of the inner wall of each of the buffer grooves.

[0011] Preferably, two sliders are fixedly connected to the outer surface of several limiting plates, and the inner surface of several buffer grooves is provided with a groove for use with the two sliders.

[0012] Preferably, a buffer pad is fixedly connected to one end of each of the buffer rods.

[0013] Preferably, the elastic protective sleeve is made of polyurethane elastomer.

[0014] Preferably, an extension plate is fixedly connected to one end of the buffer box, and a guide plate is fixedly connected to one end of the extension plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting up a protective component, when clamping materials, the buffer rod retracts into the buffer groove under pressure, and the spring undergoes elastic deformation to absorb the impact energy. Combined with the flexible contact of the polyurethane elastic buffer sleeve, the clamping impact force can be reduced, effectively avoiding damage to the material surface. It is suitable for non-destructive clamping of fragile workpieces such as precision electronic components and thin metal plates.

[0017] 2. This utility model uses a power motor to drive the lead screw to rotate, which in turn moves the adjusting block along the lead screw. With the guidance of the adjusting rod and the crossbar, the clamping block can automatically adjust the clamping distance according to the material thickness. It can adapt to different specifications of materials without manual intervention, shorten the feeder changeover time, and significantly improve production efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides a clamping feeder with a protective mechanism, including a conveyor frame 1. An electric slide rail 2 is installed on the lower inner wall of the conveyor frame 1. A moving plate 3 is slidably connected to the outer surface of the electric slide rail 2. Two cylinders 4 are fixedly connected to the bottom end of the moving plate 3. A clamping component 5 is fixedly connected to the output end of the two cylinders 4. The electric slide rail 2 can drive the moving plate 3 to move laterally, and the cylinders 4 can drive the clamping component 5 to move up and down. Through the cooperation of the electric slide rail 2 and the cylinders 4, the clamping component 5 can move flexibly in three-dimensional space, which is convenient for accurate positioning and material gripping, and improves the working range and operational flexibility of the feeder.

[0030] The clamping assembly 5 includes a fixed frame 54. The output ends of the two cylinders 4 are fixedly connected to the fixed frame 54 through a connecting frame. A power motor 57 is fixedly connected to the top of the fixed frame 54. The output end of the power motor 57 passes through the fixed frame 54 and is fixedly connected to a lead screw 56. An adjusting block 52 is threaded onto the outer surface of the lead screw 56. Two adjusting rods 55 are rotatably connected to both ends of the adjusting block 52. The two corresponding adjusting rods 55 are rotatably connected to a clamping block 51. A crossbar 53 is fixedly connected to one end of the fixed frame 54. The two clamping blocks 51 are slidably connected to the crossbar 53. A protective component 6 is installed on one end of each clamping block 51. The power motor 57 drives the lead screw 56 to rotate, causing the adjusting block 52 to move along the lead screw 56. Through the transmission of the adjusting rods 55, the clamping block 51 slides on the crossbar 53, realizing precise adjustment of the opening and closing degree of the clamping block 51. This structure can adapt to the clamping requirements of materials of different sizes, improve the versatility of the feeder, and at the same time, the crossbar 53 provides a sliding guide for the clamping block 51 to ensure the stability of the clamping action.

[0031] Specifically, the cross-section of the crossbar 53 is rectangular. The rectangular cross-section of the crossbar 53 can effectively prevent the clamping block 51 from rotating during the sliding process, ensuring that the clamping block 51 always maintains a parallel clamping state, improving the stability and accuracy of clamping materials, and avoiding the problem of materials falling or being not clamped securely due to the shaking of the clamping block 51.

[0032] like Figures 1 to 6As shown, the protective component 6 includes a buffer box 61. One end of the buffer box 61 has several circular grooves 613 arranged in a rectangular array. The inner surface of the buffer box 61 has several buffer slots 611, which are connected to the circular grooves 613. Buffer rods 617 are connected to the inner surfaces of the circular grooves 613. The buffer rods 617 pass through the circular grooves 613 and extend into the buffer slots 611. One end of each buffer rod 617 located within a buffer slot 611 is fixed. The limiting plate 615 has a spring 614 fixedly connected to one end of each limiting plate 615. The buffer box 61 has an elastic protective sleeve 64 fixedly connected to one end. Several buffer rods 617 are located inside the elastic protective sleeve 64. When the clamping block 51 clamps the material, the elastic protective sleeve 64 first contacts the material and buffers the initial impact force through its own elastic deformation. Then, during the clamping process, the buffer rods 617 will compress the spring 614 and use the elastic potential energy of the spring 614 to further absorb the impact energy, avoid excessive clamping force from damaging the material, and effectively protect the surface quality of the material.

[0033] Furthermore, one end of several springs 614 is fixedly connected to the inner wall of one side of several buffer grooves 611, ensuring that the springs 614 maintain a stable force direction during compression and reset, making the buffering action of the buffer rod 617 smoother, improving the reliability of the buffer structure and the consistency of the buffering effect, and ensuring continuous protection of materials.

[0034] like Figures 1 to 6 As shown, two sliders 616 are fixedly connected to the outer surfaces of several limiting plates 615. The inner surfaces of several buffer grooves 611 are provided with sliding grooves 612 that cooperate with the two sliders 616, which restricts the movement trajectory of the limiting plates 615, prevents the buffer rod 617 from deviating or shaking during movement, ensures that the buffer rod 617 performs buffering action in a straight line, makes the buffer structure work more stable and reliable, and avoids damage to the spring 614 due to uneven force caused by the deviation of the buffer rod 617.

[0035] It is worth noting that one end of each of the buffer rods 617 is fixedly connected to a buffer pad 618, which can effectively prevent the buffer rods 617 from directly contacting the inner wall of the elastic protective sleeve 64 and damaging the elastic protective sleeve 64.

[0036] like Figures 1 to 6 As shown, the elastic protective sleeve 64 is made of polyurethane elastomer. Polyurethane elastomer has good elasticity, wear resistance and corrosion resistance. It can effectively buffer the impact force during clamping and resist the friction between the material and the protective sleeve, thus extending the service life of the protective sleeve. At the same time, its corrosion resistance can adapt to a variety of working environments, ensuring the long-term stable operation of the protective component 6.

[0037] It is worth emphasizing that one end of the buffer box 61 is fixedly connected to an extension plate 62, and one end of the extension plate 62 is fixedly connected to a guide plate 63. The guide plate 63 can smoothly scoop up the material, improving the regularity and efficiency of material picking.

[0038] The power motor 57 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0039] Working principle and process: When the feeder is working, the electric slide rail 2 on the inner wall of the conveyor frame 1 first drives the moving plate 3 to move laterally, and the cylinder 4 drives the clamping assembly 5 to rise and fall vertically, so that the clamping block 51 is positioned above the material. Then the power motor 57 is started. After the power motor 57 starts, it drives the lead screw 56 to rotate. Through the transmission of the adjusting block 52 and the adjusting rod 55, the clamping block 51 slides on the rectangular crossbar 53 to realize the opening and closing degree adjustment to adapt to the material size. During the clamping process, the polyurethane elastic protective sleeve 64 first contacts the material to buffer the initial impact. Then the buffer rod 617 compresses the spring 614 for secondary buffering. The buffer pad 618 directly contacts the elastic protective sleeve 64, which can effectively avoid damage to the elastic protective sleeve 64. After successful clamping, the cylinder 4 lifts the clamping block 51, and the electric slide rail 2 moves to the unloading station to complete the feeding cycle.
