Description

Technical Field

[0001] This utility model relates to the field of automatic detection equipment technology, specifically a drawer device used for loading and unloading materials. Background Technology

[0002] Existing automated inspection equipment requires manual placement of the material tray into a designated area inside the equipment. The equipment's robotic arm then picks up and places the material, replacing the tray at regular intervals. However, when the tray is large or the robotic arm's structure requires a distance from the outer casing, causing the tray to be positioned slightly inside the equipment, the worker must lean into the machine and bend over to pick up or place the tray. To ensure worker safety, this process stops the entire machine, reducing inspection efficiency. Furthermore, the bending motion results in a poor user experience. Therefore, a structure is needed to assist in tray handling that balances safety, equipment efficiency, and a positive user experience. The existing solution is to directly adopt a drawer structure with a three-section slide rail arrangement. The tray placement area is designed into the drawer structure. When retrieving or placing the tray, the drawer can be pulled out to retrieve or place the tray outside the equipment. When multiple sets are used, this can ensure efficiency and worker safety without stopping production. However, there are also many defects and shortcomings. The length of the three-section slide rail is L (when closed). The fully extended length is about twice its closed length, that is, the slide rail travel is about its own length L. Therefore, when it is arranged in the drawer structure, it is necessary to ensure that the drawer can be closed inside the equipment cover and fully pulled out outside the equipment. Therefore, the drawer structure can only be arranged with the equipment cover as the alignment surface of the three-section slide rail. Thus, the area where the tray can be placed inside the equipment must be within a distance L from the equipment cover, and the maximum length of the tray is L.

[0003] Some robotic material handlers, due to their structural design, have a material-picking nozzle or clamp positioned at a distance X from the equipment's outer casing. To achieve automated material handling, the material tray must be placed within a range of L to X distance from the outer casing inside the equipment. This changes the tray length from L to LX, increasing the frequency of manual loading and unloading and increasing workload. Maintaining the tray's placement within a certain distance from the outer casing restricts the layout of other internal components, increasing design complexity and efficiency. Furthermore, when the drawer is pulled out, the tray's position near the outer casing leaves an empty space of X length on the outside of the drawer, resulting in an unsightly layout and negatively impacting user experience.

[0004] To address this problem, we designed a drawer device for loading and unloading materials. Utility Model Content

[0005] The purpose of this invention is to provide a drawer device for loading and unloading materials, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a drawer device for loading and unloading materials, including a slide structure and a drawer structure connected to the slide structure. The slide structure can drive the drawer structure to slide back and forth as a whole to compensate for the gap between the mechanical material handling hand and the equipment cover. The slide structure includes a push-pull cylinder connected to the worktable, and the telescopic end of the push-pull cylinder is connected to a slide frame. The drawer structure includes a three-section slide rail connected to the slide frame, a material tray support frame connected to the three-section slide rail, and a material tray body connected to the material tray support frame.

[0007] Furthermore, the slide structure also includes two linear guide rails connected to the worktable, and the two linear guide rails are arranged symmetrically to each other, with the carriage slidably connected to the linear guide rails.

[0008] Furthermore, an adsorption magnet is connected to one side of the tray support frame, and a magnetic iron block is connected to the slide. The magnetic iron block and the adsorption magnet are on the same plane and can be attracted and fixed to each other.

[0009] Furthermore, a proximity switch A is connected to one side of the tray support frame, and a proximity switch B is connected to the slide. The proximity switches A and B are on the same plane and can be mutually sensed to control the push-pull cylinder.

[0010] Furthermore, it also includes a positioning structure connected to the worktable, and the positioning structure is located on the side of the slide structure away from the drawer structure. The positioning structure includes a positioning block and an electromagnet connected to the positioning block. The positioning surface of the positioning block is provided with a pin hole for inserting a pin. A positioning iron plate is connected to one side of the tray support frame. When the push-pull cylinder retracts, the pin is inserted into the positioning hole on the positioning iron plate, and at the same time, the electromagnet is energized to generate magnetic force, attracting the positioning iron plate.

[0011] Furthermore, the tray body includes a tray body connected to a tray support frame, a tray handle connected to the tray body, and a product placed on the tray body.

[0012] Furthermore, a sensor switch for sensing the material tray body is connected to one side of the carriage.

[0013] Furthermore, a cable tray is connected to one side of the carriage.

[0014] Furthermore, the upper cylinder of the push-pull cylinder has damping adjustment knobs at both ends of the cylinder body, which are used to buffer the slide structure.

[0015] Furthermore, a drawer handle is connected to the side of the tray support frame away from the positioning iron plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The sliding cylinder of the sliding table structure drives the drawer structure to slide as a whole, which makes up for the gap between the mechanical material handling hand and the equipment cover. This solves the limitation that the material tray must be placed within the range of the cover, restores the length of the material tray to the slide rail stroke, reduces the frequency and intensity of manual loading and unloading, and allows the manual to pull the material tray out of the equipment through the drawer handle without having to bend down and reach into the equipment.

[0017] 2. Linear guide rails provide guidance for the sliding table, and damping adjustment knobs buffer impacts to prevent the tray from vibrating and shifting; magnetic magnets and magnetic blocks ensure the drawer closes during movement; proximity switches enable automatic cylinder control; induction switches can promptly remind users of any missed trays; and the positioning structure uses pins in conjunction with electromagnetic adsorption to ensure material handling accuracy.

[0020] 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.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a drawer device for loading and unloading materials, including a slide structure 2 and a drawer structure 1 connected to the slide structure 2. The slide structure 2 can drive the drawer structure 1 to slide back and forth as a whole to compensate for the gap between the mechanical material handling hand and the equipment cover. The slide structure 2 includes a push-pull cylinder 24 connected to the workbench, and the telescopic end of the push-pull cylinder 24 is connected to a slide frame 21. The drawer structure 1 includes a three-section slide rail 16 connected to the slide frame 21, a material tray support frame 13 connected to the three-section slide rail 16, and a material tray body 12 connected to the material tray support frame 13.

[0022] In practical implementation, in the slide structure 2, when the push-pull cylinder 24 connected to the worktable extends or retracts, it can drive the slide frame 21 connected to its extension end to slide back and forth; the drawer structure 1 connects the tray support frame 13 to the slide frame 21 through the three-section slide rail 16, and the tray body 12 is placed on the tray support frame 13. When loading and unloading, the push-pull cylinder 24 drives the slide frame 21 and the drawer structure 1 to move as a whole to compensate for the gap between the mechanical material handling arm and the equipment cover. At the same time, the three-section slide rail 16 allows the tray support frame 13 to be pulled out relative to the slide frame 21, realizing the loading and unloading of the tray outside the equipment.

[0023] See Figure 1-7 The slide structure 2 also includes two linear guide rails 23 connected to the worktable, and the two linear guide rails 23 are symmetrically arranged. The slide 21 is slidably connected to the linear guide rails 23.

[0024] In practice, when the push-pull cylinder 24 drives the slide 21 to move, the linear guide rail 23 provides stable support and guidance for the slide 21.

[0025] See Figure 1-7 A magnet 14 is connected to one side of the tray support frame 13, and a magnetic iron block 22 is connected to the slide 21. The magnetic iron block 22 and the magnet 14 are on the same plane and can be attracted and fixed to each other.

[0026] In practice, when the tray support frame 13 is reset to the corresponding position of the slide 21 via the three-section slide rail 16, the adsorption magnet 14 and the magnetic iron block 22 attract each other, so that the drawer structure 1 remains closed.

[0027] See Figure 1-7A proximity switch A17 is connected to one side of the tray support frame 13, and a proximity switch B25 is connected to the slide 21. The proximity switches A17 and B25 are on the same plane and can sense each other to control the push-pull cylinder 24.

[0028] In practice, when the tray support frame 13 is reset to the designated position on the slide 21, the two proximity switches sense each other and send an electrical signal, which is transmitted to the equipment system to control the push-pull cylinder 24 to move.

[0029] See Figure 1-7 It also includes a positioning structure 3 connected to the workbench, and the positioning structure 3 is located on the side of the slide structure 2 away from the drawer structure 1. The positioning structure 3 includes a positioning block 31 and an electromagnet 32 ​​connected to the positioning block 31. The positioning surface of the positioning block 31 is provided with a pin hole for inserting a pin. A positioning iron plate 15 is connected to one side of the tray support frame 13. When the push-pull cylinder 24 retracts, the pin is inserted into the positioning hole on the positioning iron plate 15, and at the same time, the electromagnet 32 ​​is energized to generate magnetic force and attract the positioning iron plate 15.

[0030] In practice, when the push-pull cylinder 24 retracts and drives the drawer structure 1 to reset, the pin in the pin hole of the positioning block 31 is inserted into the positioning hole of the positioning iron piece 15 on the tray support frame 13, and at the same time the electromagnet 32 ​​is energized to attract the positioning iron piece 15, thereby realizing the positioning of the tray.

[0031] See Figure 1-7 The tray body 12 includes a tray body 121 connected to the tray support frame 13, a tray handle 122 connected to the tray body 121, and a product 123 placed on the tray body 121.

[0032] In practice, the tray body 121 is placed on the tray support frame 13 through the positioning hole, the product 123 is placed inside the tray body 121, and the tray body 121 is picked up and put down manually through the tray handle 122.

[0033] See Figure 1-7 A sensor switch 27 for sensing the material tray body 12 is connected to one side of the carriage 21.

[0034] In practice, the induction switch 27 on one side of the carriage 21 detects in real time whether the tray body 12 is placed on the tray support frame 13. If the tray is not detected, the induction switch 27 sends a signal to the equipment system to trigger an alert action.

[0035] See Figure 1-7 One side of the carriage 21 is connected to a cable tray 26.

[0036] In practice, the cable tray 26 is connected to one side of the slide 21, and the cable of the device is stored in the cable tray 26 and moves synchronously with the slide 21.

[0037] See Figure 1-7 The push-pull cylinder 24 has damping adjustment knobs at both ends of the cylinder body, which are used to buffer the slide structure 2.

[0038] In practice, by controlling the airflow speed inside the cylinder, the movement speed of the slide 21 when it starts and stops is slowed down, thus buffering the movement of the slide structure 2.

[0039] See Figure 1-7 A drawer handle 11 is connected to the side of the tray support frame 13 away from the positioning iron plate 15.

[0040] In practice, the drawer handle 11 is connected to the side of the tray support frame 13 away from the positioning iron plate 15. By manually pulling or pushing the drawer handle 11, the tray support frame 13 is pulled out or reset relative to the slide frame 21 along the three-section slide rail 16.

[0041] Working principle: After receiving a signal, the push-pull cylinder 24 extends, and its telescopic end drives the slide 21 to slide outward along the two linear guide rails 23 symmetrically arranged on the worktable. The linear guide rails 23 provide stable support and guidance for the slide 21. The drawer structure 1 connected to the slide 21 moves synchronously with the slide 21 until the slide structure 2 moves to the preset position. At this time, the drawer structure 1 is close to the outer cover of the equipment, which completes the compensation of the distance between the mechanical material handling hand and the outer cover of the equipment. During this process, the adsorption magnet 14 on the tray support frame 13 and the magnetic iron block 22 on the slide 21 remain in an adsorption state, so that the drawer structure 1 remains closed. Manually grasp the drawer handle 11 on one side of the tray support frame 13 and pull the tray support frame 13 outward. The tray support frame 13 slides outward relative to the slide frame 21 along the three-section slide rail 16 connected to the slide frame 21 until the three-section slide rail 16 is fully extended and automatically locked in place, maintaining the open posture. Manually remove the tray body 12 placed on the tray support frame 13 through the tray handle 122 on the tray body 121 to complete the replenishment or removal of the product 123. Then, put the processed tray body 12 back onto the tray support frame 13 through the positioning hole of the tray body 121. Manually push the drawer handle 11 to drive the tray support frame 13 back to the slide frame 21 along the three-section slide rail 16 until the tray support frame 13 is in contact with the slide frame 21. At this time, the adsorption magnet 14 and the magnetic iron block 22 attract and fix each other, keeping the drawer structure 1 in the closed state. After the tray support frame 13 is reset, the proximity switch A17 on it and the proximity switch B25 on the slide 21 sense each other, send an electrical signal and transmit it to the equipment system. The system determines that the drawer structure 1 is in place and then sends a retraction signal to the push-pull cylinder 24. At the same time, the induction switch 27 on one side of the slide 21 detects whether the tray body 12 has been placed on the tray support frame 13. If no tray is detected, an alert signal is issued. After receiving the retraction signal, the push-pull cylinder 24 retracts, causing the slide 21 and drawer structure 1 to slide along the linear guide rail 23 into the equipment. The damping adjustment knobs at both ends of the push-pull cylinder 24 control the airflow speed inside the cylinder, slowing down the movement speed of the slide 21 when it starts and stops, thus buffering the movement of the slide structure 2 and avoiding impact and vibration. When the push-pull cylinder 24 is fully retracted and the drawer structure 1 reaches the preset material retrieval position, the pin in the pin hole of the positioning block 31 in the positioning structure 3 is inserted into the positioning hole of the positioning iron piece 15 on the material tray support frame 13. At the same time, the electromagnet 32 ​​on the positioning block 31 is energized to generate magnetic force, attracting the positioning iron piece 15. Through the combined use of pin insertion and electromagnetic adsorption, the positioning of the material tray body 12 is achieved.

[0042] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
