DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0021] This embodiment relates to a silo type feeding device, referring to Figure 1-Figure 3, including: an operating table, a silo 200, a driving mechanism and a material picking mechanism 400. The silo 200 is assembled on the operating table; the silo 200 is used to place materials 800; and the silo 200 is provided with at least one. The driving mechanism is assembled on the operating table and is located above the silo 200; the material picking mechanism 400 is assembled at one end of the driving mechanism facing the silo 200; the driving mechanism is used to drive the material picking mechanism 400 to move in the X direction and / or the Z direction to complete the loading. Specifically, the material picking mechanism 400 is assembled at one end of the driving mechanism facing the silo 200, and the driving mechanism is used to drive the material picking structure to move in the X direction and the Z direction to complete the loading, that is, the driving mechanism can drive the material picking mechanism 400 to move in the horizontal direction and the vertical direction to complete the production process of picking, moving and loading. The driving mechanism cooperates with the material picking structure to complete the automatic material picking, which can effectively improve the overall production efficiency, is flexible and efficient in operation, and is convenient for subsequent production work. The overall structure of this silo-type loading device is simple, and it occupies a small area. It is suitable for places with limited production space and can save production costs. In this embodiment, two silos 200 are provided and arranged side by side. The two silos 200 are independently provided so that when the drive mechanism drives the material taking structure to take out the material 800 from one silo 200, that is, when one of the silos 200 is empty, it automatically switches to the other silo 200 to take out the material, so as to achieve uninterrupted loading, reduce the time of stopping for material replacement or replenishment, and save production time. The two silos 200 are arranged side by side to save space, and also avoid the silos 200 being dispersed and causing the material taking stroke to be too long, thereby ensuring the efficiency of the material taking structure switching between the two silos 200. In some embodiments, four silos 200 can also be provided. In some embodiments, the drive mechanism is used to drive the material taking mechanism to move in the X direction or the Z direction to complete the loading.

[0022] Further, refer to Figure 1-Figure 3 The silo-type loading device further includes: a limiting column 600 having one end disposed in the silo 200 and the other end extending vertically upward; a plurality of limiting columns 600 are provided; and the plurality of limiting columns 600 are used to divide the silo 200 into a plurality of material placement areas 210. The limiting columns 600 physically separate the material placement areas 210 to prevent different materials 800 from mixing, ensuring that the material picking mechanism 400 accurately grabs the target material 800 and reducing the risk of wrong materials. Each material placement area 210 can limit the stacking range of the material 800 to avoid the failure of the material 800 to be picked up due to skewed stacking. The limiting columns 600 play the role of guiding the material 800 to be stacked neatly, thereby improving the success rate of material picking.

[0023] In this embodiment, referring to Figure 2The operating table includes a platform 110 on which the material bin 200 is mounted, and a support frame 120 for mounting the drive mechanism. The support frame 120 includes a first support member 121 and a second support member 122. The first support member 121 has one end mounted on the platform 110 and located around the material bin 200, with its free end extending vertically upward. The second support member 122 has one end connected to the free end of the first support member 121 and its other end extending horizontally. The second support member 122 is arranged parallel to the material bin 200. The first support member 121 is perpendicular to the platform 110, with its free end extending vertically upward. This allows the drive mechanism sufficient space for vertical movement and facilitates the stacking of materials 800 to a certain height in the material bin 200, allowing for greater storage capacity. The second support member 122 has one end connected to the first support member 121 and its other end extending horizontally. This ensures that the movement path of the material retrieving mechanism 400 aligns with that of the material bin 200, improving material retrieving accuracy.

[0024] Furthermore, the support frames 120 are arranged in an L-shape. Two sets of support frames 120 are provided; these two sets of support frames 120 are positioned opposite each other and on either side of the silo 200 to ensure stable assembly of the drive mechanism, thereby preventing structural tilt or deformation caused by unilateral support and improving the overall stability and service life of the silo-type loading device. Specifically, the two support frames 120 are arranged as one set, i.e., the two sets of support frames 120 are provided with a total of four support frames 120, located on all sides of the silo 200.

[0025] Furthermore, a clearance opening 500 is provided between the two sets of support frames 120; this clearance opening 500 is used to clear the end of the drive mechanism equipped with the material retrieving mechanism 400. Specifically, during production operations, this silo-type loading device serves to deliver material 800 to the equipment responsible for the next production step (for example, a device for cleaning material 800 or a device for inspecting material 800). The provision of the clearance opening 500 prevents mechanical interference between the material retrieving mechanism 400, the drive mechanism, and the support frames 120, facilitating the delivery of material 800 to the designated loading point and ensuring smooth production operations.

[0026] In this embodiment, referring to Figure 1-Figure 3The drive mechanism includes: an X-axis guide assembly 310, a connector 320, an X-axis drive assembly 330, a Z-axis guide assembly 340, and a Z-axis drive assembly 350. The X-axis guide assembly 310 is horizontally arranged on the second support member 122; one end of the X-axis guide assembly 310 extends away from the operating table; the connector 320 is slidably assembled on the X-axis guide assembly 310; the X-axis drive assembly 330 is arranged at one end of the X-axis guide assembly 310; the output end of the X-axis drive assembly 330 is transmission-connected to the X-axis guide assembly 310; the Z-axis guide assembly 340 is fixedly mounted on the connector 320; the Z-axis drive assembly 350 is slidably assembled on the Z-axis guide assembly 340 and reciprocates in the vertical direction; a material picking mechanism 400 is arranged at the end of the Z-axis drive assembly 350 facing the hopper 200; under the action of the X-axis drive assembly 330, the connector 320 reciprocates horizontally relative to the hopper 200 along the X-axis guide assembly 310. Specifically, one end of the X-axis guide assembly 310 extends away from the operating table to facilitate the retrieving mechanism 400 in moving the material 800 out of the hopper 200 to the designated loading point. The X-axis guide assembly 310 and the Z-axis guide assembly 340 provide precise guidance for the movement of the retrieving mechanism 400, reducing deviation and shaking during movement and ensuring the accuracy of the movement of the retrieving mechanism 400. The X-axis guide assembly 310 cooperates with the X-axis drive assembly 330 to drive the retrieving mechanism 400 to move the material 800 horizontally to the designated loading point. The Z-axis guide assembly 340 and the Z-axis drive assembly 350 drive the retrieving mechanism 400 to move up and down to suck in or grab the material 800.

[0027] In this embodiment, the connector 320 is slidably mounted on the X-axis guide assembly 310 via an X-axis slider. The X-axis guide assembly 310 includes two linear guide rails arranged side by side to achieve smooth horizontal movement of the material removal mechanism 400. Two X-axis sliders are provided, each slidably mounted on the two linear guide rails. The ends of the connector 320 are fixed to the two X-axis sliders. The X-axis drive assembly 330 includes an X-axis drive device, a ball screw connected to the output end of the drive motor, and a synchronizer for simultaneously driving the two X-axis sliders to slide. The ball screw includes a screw connected to the output end of the drive motor, a nut, and a ball. The X-axis slider is fixedly connected to the nut in the ball screw. The X-axis drive device drives the screw to rotate. The ball rolls in the spiral groove of the screw and nut, converting the rotational motion into linear motion of the nut. The nut then drives the X-axis slider to reciprocate along the linear guide rails. In some embodiments, the X-axis drive assembly 330 and the X-axis guide assembly 310 can also be a combination of a servo motor and a synchronous belt. The Z-axis guide assembly 340 includes: two Z-axis sliders fixedly mounted on the connector 320 and a Z-axis transmission block fixed on the connector 320. The Z-axis drive assembly 350 includes: a Z-axis drive device and a Z-axis screw connected to the output end of the Z-axis drive device. The Z-axis screw cooperates with the Z-axis transmission block. Driven by the Z-axis drive assembly 350, the Z-axis screw moves in the vertical direction relative to the Z-axis transmission block, thereby enabling the Z-axis drive device as a whole to perform reciprocating motion in the vertical direction relative to the Z-axis slider, ultimately enabling the material-retrieving mechanism 400 to complete the functions of descending to retrieve materials and ascending to move materials, thereby ensuring that the materials are fed to the designated loading point. In this embodiment, the X-axis drive device and the Z-axis drive device are stepper motors. In some embodiments, the Z-axis guide assembly 340 and the Z-axis drive assembly 350 can also be a servo motor and a synchronous belt.

[0028] Furthermore, the material retrieving mechanism 400 includes an extension plate 410, an extension column 420, and a retrieving device 430. The extension plate 410 is positioned at the end of the Z-axis drive assembly 350 facing the silo 200. The extension column 420 has one end positioned on the side of the extension plate 410 facing the silo 200, with its free end extending vertically toward the silo 200. Multiple extension columns 420 are provided, arranged side by side. One end of the retrieving device 430 is mounted on the free end of the extension column 420. The retrieving end of the retrieving device 430 faces the silo 200. Multiple retrieving devices 430 are provided. Multiple, side-by-side extension columns 420 and retrieving devices 430 enable the simultaneous retrieval of multiple materials 800, significantly increasing the amount of material loaded per operation. This is particularly useful in batch production scenarios, reducing the number of material retrievals and improving overall efficiency. Multiple retrieving devices 430 can operate independently or simultaneously, adapting to multiple material storage areas 210 within the silo 200 and accommodating simultaneous retrieval of materials 800 of varying specifications, enhancing the device's flexibility. In this embodiment, the material picking device 430 is configured as a vacuum suction nozzle, and the silo-type loading device further includes: a material picking in place detection device 730 for detecting and measuring the vacuum degree within the material picking device 430. Specifically, the material picking in place detection device 730 is a vacuum sensor for detecting and measuring the vacuum degree within the enclosed space, i.e., the vacuum suction nozzle. When the vacuum suction nozzle adsorbs the material 800 into place, a material picking in place signal is issued, at which point the material 800 can be moved; when the vacuum suction nozzle is still in a vacuum leaking state, the material picking in place detection device 730, i.e., the vacuum sensor, detects that there is a gas leak in the vacuum system, i.e., the vacuum suction nozzle, causing the vacuum degree in the system to be unable to maintain the set value, or the vacuum degree decrease rate exceeds the normal range, indicating that the material is not picked up in place. In some embodiments, the material picking device 430 can also be a vacuum tube. The material picking in place detection device 730 can also be a vacuum leak detector.

[0029] This embodiment also relates to a method for automatically finding a height to take materials. Figure 4 The automatic height-finding material-taking method is implemented based on the above-mentioned silo-type loading device. The automatic height-finding material-taking method includes the following steps: S100, start taking materials, control the taking material mechanism 400 to descend to a preset position according to a preset height value; S200 , controlling the material taking mechanism 400 to continue to descend from the preset position and turning on the material taking position detection device 730 .

[0030] S300, when receiving the material taking position signal sent by the material taking position detection device 730, controlling the material taking mechanism 400 to stop descending and obtaining the current height value corresponding to the current material taking point where the material taking mechanism 400 is located; S400, based on the current height value and the thickness value of the material 800, obtaining the next moving height value for the next material removal; S500, controlling the material taking mechanism 400 to move the material 800 to the loading point for unloading; S600, after the material taking mechanism 400 has finished unloading, the material taking mechanism 400 is controlled to move to the next material taking point according to the next moving height value to take the material; S700 , repeat steps S300 - S600 until receiving a signal indicating that there is no material in the current silo 200 from the silo detection device 720 , then stop taking material from the current silo 200 and control the taking mechanism 400 to move to the next silo 200 .

[0031] Specifically, through steps S100 to S700, the process of taking materials, updating height data, unloading materials, and taking materials again is executed cyclically, with a high degree of automation, and can realize automatic switching of the silo 200, thereby realizing full-process automated material taking.

[0032] In this embodiment, referring to Figure 5 The silo-type loading device further includes: a control device 710 for controlling the X-axis drive device and the Z-axis drive device to drive the material picking mechanism 400 to move in the X-axis and Z-axis directions, and a silo detection device 720 for detecting whether there is material 800 in the silo 200; the control device 710 is electrically connected to the X-axis drive device, the Z-axis drive device, the material picking position detection device 730, and the silo detection device 720. The control device 710 also includes: a control unit and a data processing unit, wherein the control unit receives the material picking position signal sent by the material picking position detection device 730 and the material presence or absence signal sent by the silo detection device 720, and the control unit is further used to control the X-axis drive device and the Z-axis drive device to complete the material picking, material transfer, and material loading actions.

[0033] In step S100, the material is retrieved and a preset height value is pre-entered into the control unit. The preset height value is set by the operator according to the height of the stack of materials 800. The control unit controls the Z-axis drive device to drive the material retrieval mechanism 400 to quickly descend to the preset position, saving descent time. In steps S200-S300, the control unit controls the Z-axis drive device and then controls the material retrieval mechanism 400 to continue to slowly descend from the preset position, and turns on the material retrieval position detection device 730, i.e., the vacuum sensor. When the vacuum nozzle touches the material 800, it starts to suck vacuum until the material retrieval position detection device 730 sends a material retrieval position signal, i.e., the vacuum sensor sends a signal that the material is in place. When the control unit receives the signal, it controls the Z-axis drive device to stop, i.e., stops driving the material retrieval mechanism 400 to descend, and obtains the current height value corresponding to the current material retrieval point where the material retrieval mechanism 400 is located. In step S400, the data processing unit calculates the next moving height value based on the current height value and the thickness of material 800 (input by the operator based on the thickness of a standard material). The data processing unit then sends this value to the control unit, which controls the Z-axis drive device to drive the reclaiming mechanism 400 for the next material reclaim. Subsequently, in step S500, the control unit controls the reclaiming mechanism 400 to move the material 800 to a discharge point for unloading. The discharge point is located on the production line for the next production step, such as cleaning or testing. In step S600, after the reclaiming mechanism 400 has finished unloading, the control unit controls the Z-axis drive device to move the reclaiming mechanism 400 to the next reclaiming point for reclaiming according to the next moving height value. The next reclaiming point is the location where the next material 800 is to be picked up, enabling layer-by-layer loading. In step S700, steps S300-S600 are repeated until a signal indicating that the current silo 200 is empty is received from the silo detection device 720. Retrieving material from the current silo 200 is stopped, and the retrieving mechanism 400 is controlled to move to the next silo 200. Specifically, the silo-type loading device further includes an alarm device 740 electrically connected to the silo detection device 720 and the control device 710. When the silo detection device 720 issues a signal indicating that the silo 200 is empty, the control unit in the control device 710 transmits the signal to the alarm device 740, which then issues an alarm message to remind the operator to refill the silo.

[0034] Compared with the traditional loading method, in which the next material picking height needs to be reset after each layer of material 800 is taken, this method obtains the next moving height value based on the current height value and the thickness value of the material 800, that is, the top position of the remaining material 800 in order to pick up the next layer of material 800, and adapts to the dynamic changes in the stacking height of the material 800 to automatically explore the height, allowing the picking mechanism 400 to quickly descend to the picking point of the next material 800 without having to move a long distance from the preset position, shortening the time for a single material picking, saving production time and improving the overall picking efficiency.

[0035] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
