[0043] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] The track-type conveying device provided in this embodiment is mainly suitable for scenarios involving moving targets such as moving materials, products, and workpieces. For example, it can be used for chip conveying scenarios in semiconductor processing scenarios, circuit board conveying scenarios in circuit board processing scenarios, and can also be used for smart home scenarios such as curtain movement of smart curtains. It aims to provide a conveying device with higher stability for mobile targets, and in this embodiment, the structure of the track-type conveying device is also improved to reduce its fragility and extend its service life.

[0047] like Figure 1 As shown, the track-type conveying device in this embodiment includes a track body 100, a bearing part 200, a lifting assembly 300 and a locking assembly 400; wherein the track body 100 is extended along a first direction; the bearing part 200 includes a bearing body 210 and two flexible end parts 220, along the first direction, the bearing body 210 is arranged between the two flexible end parts 220, and the bearing body 210 is slidably connected to the track body 100 through the flexible end parts 220, that is, in the first direction, the bearing body 210 is slidably connected to the track body 100 through the front and rear flexible end parts 220, and the bearing body 210 can be used as a transport carrier of a mobile target, for example, it can install a pallet, a bracket, a curtain, etc.

[0048] At the same time, the lifting assembly 300 is arranged between the flexible end 220 and the carrier body 210, and is used for the flexible end 220 to be slidably connected with the carrier body 210 along the second direction; the second direction is perpendicular to the plane where the track body 100 is located; the locking assembly 400 is used to lock the relative position of the flexible end 220 relative to the carrier body 210 along the second direction. It can be understood that according to different load conditions, there will be an imbalance between the two ends of the flexible end 220, one in front and one behind. If one of the flexible ends 220 is too close to the track body 100, a dead point is likely to occur, resulting in jamming; at this time, the flexible end 220 is unlocked by the locking assembly 400, and the positions of the two flexible ends 220 are leveled by manual or automatic adjustment, so that the situation where the flexible end 220 is too close to the track body 100 can be eliminated, thereby improving the stability of transportation.

[0049] In summary, the rail conveying device in this embodiment conveys materials through the bearing part 200, and its bearing body 210 uses the flexible ends 220 on both sides along the first direction to achieve a flexible sliding connection with the rail body 100, which means that the bearing body 210 can be buffered by the flexible ends 220 during the conveying process to extend the overall life; at the same time, when the overall offset is large and causes one flexible end 220 to be too close to the rail body 100, the flexible end 220 can be unlocked by the locking assembly 400, and then the flexible end 220 can be slid on the bearing body 210 along the second direction to adjust the position of the flexible end 220, for example, the other flexible end 220 can be adjusted to be close to the rail body 100, so that the two flexible ends 220 and the bearing body 210 can maintain balance, avoid causing the flexible end 220 to be stuck, and then ensure the overall stability. Therefore, the rail conveying device has the advantages of low fragility and high stability.

[0050] Furthermore, if Figure 2As shown, the flexible end portion 220 includes a movable housing 221 slidably connected to the carrier body 210, and the movable housing 221 is slidably connected to a hook unit 222 in the second direction; a hook spring 223 is arranged between the hook unit 222 and the movable housing 221, one end of the hook spring 223 is connected to the movable housing 221, and the other end of the hook spring 223 is connected to the hook unit 222, so that the hook unit 222 has a tendency to move in a direction away from the track body 100. At the same time, the track body 100 can be provided with a slider, a guide block and other sliding parts that can slide on the track body 100 corresponding to the hook unit 222, and the sliding parts are correspondingly provided with hooks, hook-through parts with mounting holes (for the hook unit 222 to pass through), hanging rings and other connecting parts that can be non-rigidly connected to the hook unit 222. It can be understood that the carrier body 210 can be flexibly connected to the above-mentioned connecting parts through the hook unit 222 and the hook spring 223, so that the carrier body 210 can slide along the track body 100 and have a buffering ability in the second direction, thereby improving the overall stability.

[0051] Based on the above implementation, Figure 4 and Figure 5 As shown, the lifting assembly 300 includes a slide 301 protruding from the carrying body 210, the number of the slides 301 is two and they are arranged opposite to each other, and a slide groove 302 is opened on the side facing each other of the two slides 301; Figure 7 and Fig. 9 As shown, the flexible end portion 220 includes a sliding portion 224 arranged corresponding to the slide groove 302, and the sliding portion 224 protrudes from the movable housing 221. The movable housing 221 includes a movable bottom shell 2211 and a movable cover 2212, and the movable bottom shell 2211 protrudes from the movable cover 2212, thereby forming a sliding portion 224, and the sliding portion 224 can slide in the slide groove 302, and cooperate with the locking assembly 400 to fix the sliding portion 224 in the slide groove 302 in the second direction, thereby fixing one end of the hook spring 223, and at the same time, the hook unit 222 is lifted and lowered with the carrier body 210 through the other end of the hook spring 223, and the hook unit 222 is flexibly slidable with the track body 100 through the connecting member and the sliding part in turn.

[0052] Furthermore, if Figure 2 , Figure 3 and Figure 7As shown, the hook unit 222 is provided with a lifting block 225 at the other end corresponding to the hook spring 223, and the other end of the hook spring 223 abuts against the lifting block 225; the lifting block 225 is provided with a probe part 226, and the movable housing 221 is provided with an avoidance groove 2213 at the position corresponding to the probe part 226, and a scale part 2214 is provided at the notch edge of the avoidance groove 2213. The staff can quickly adjust the level by observing the relative position relationship between the probe part 226 and the scale part 2214. For example, if the probe part 226 in the flexible end part 220 on one side shows a higher scale, the flexible end part 220 on one side can be adjusted at this time, so that the movable housing 221 moves in the direction close to the track body 100, and the movable housing 221 is moved to a position where the probe parts 226 on both sides show the same scale, thereby improving the stability of transportation.

[0053] In an optional embodiment, the locking assembly 400 includes a limit rack 401 disposed on the lifting assembly 300 and a movable rack 410 slidably connected to the movable housing 221, and the movable rack 410 can slide in a direction away from or close to the limit rack 401; a positioning spring (not shown) is also disposed between the movable housing 221 and the movable rack 410, one end of the positioning spring is connected to the movable housing 221, and the other end of the positioning spring is connected to the movable rack 410, so that the movable rack 410 has a tendency to move in a direction close to the limit rack 401. It should be noted that in this embodiment, the number of movable racks 410 corresponding to the movable housing 221 can be one or two (the movable housing 221 is disposed between the two movable racks 410).

[0054] In another optional embodiment, the locking assembly 400 includes two symmetrically arranged limit racks 401 arranged on the lifting assembly 300 and two symmetrically arranged movable racks 410, and the movable racks 410 are arranged one by one corresponding to the limit racks 401; the locking assembly 400 also includes a trigger button 420 arranged corresponding to the movable rack 410, and the movable rack 410 is arranged on the trigger button 420; the trigger button 420 is slidably connected to the movable shell 221, and a positioning spring is arranged between the two trigger buttons 420, and the positioning spring enables the movable rack 410 to have a movement tendency in the direction close to the limit rack 401.

[0055] In the above two embodiments, the staff can overcome the pressure of the positioning spring by pressing the trigger button 420, so that the movable rack 410 is separated from the limiting rack 401, so that the position of the movable shell 221 can be adjusted; once the staff lets go, the movable rack 410 can be re-engaged with the limiting rack 401 under the action of the positioning spring, so that the movable shell 221 is fixed relative to the supporting body 210.

[0056] Furthermore, if Figures 4 to 6 , Figure 8 , Fig. 9 As shown, an electromagnetic column 510 is also arranged between the two trigger buttons 420, and a magnetic block that can be magnetically attracted by the electromagnetic column 510 is embedded on the trigger button 420; the electromagnetic column 510 is a part that has magnetism when powered on and demagnetizes when powered off, and the magnetic block is a part that can be attracted by magnetic force, such as an iron block. A positioning seat 520 is installed on the movable shell 221, and the positioning seat 520 is arranged between the two trigger buttons 420. The positioning seat 520 is provided with a positioning hole 521, and the edge of the positioning hole 521 is provided with a positioning platform 522 protruding outwardly. The electromagnetic column 510 penetrates the positioning hole 521, and one end of the positioning spring is sleeved outside the positioning platform 522. The magnetism of the electromagnetic column 510 can attract the two trigger buttons 420 to approach each other, so as to realize the automatic unlocking of the movable shell 221.

[0057] As a supplementary embodiment, a driving structure such as a lifting cylinder or a lifting motor can be provided on the carrier body 210, so that after the electromagnetic column 510 unlocks the trigger button 420, the driving structure can be used to change the position of the movable housing 221, thereby maintaining the balance of the two flexible ends 220. In other words, the electromagnetic column 510 and the driving structure can dynamically adjust the balance during the operation of the track-type conveying device, further improving the stability.

[0058] An electromagnetic locking seat 530 is installed on the positioning seat 520, and an arc-shaped groove is opened on the electromagnetic locking seat 530; the arc-shaped groove is slidably connected to the electromagnetic sleeve 540, and the electromagnetic locking seat 530 is used to lock the electromagnetic sleeve 540; the electromagnetic column 510 passes through the electromagnetic sleeve 540 and is fixedly connected to the electromagnetic sleeve 540 through the clamp ring 550; a pull-wire encoder for detecting the position of the electromagnetic column 510 is also installed on the movable housing 221. The pull-wire encoder is well known to those skilled in the art and will not be specifically expanded. It can be set in the movable housing 221 or in the interior of the bearing body 210 without specific restrictions. The electromagnetic locking seat 530 has the same principle as the electromagnetic column 510. It fixes the electromagnetic sleeve 540 through the magnetism obtained by powering on. With the above arrangement, the wear detection of the rack structure can be realized in the limited space of the movable housing 221, and has the advantage of compact structure.

[0059] Before starting the track-type conveyor device, or after the track-type conveyor device has been running for a period of time, the track-type conveyor device can be made to enter a self-test; at this time, by demagnetizing the electromagnetic locking seat 530, the electromagnetic column 510 can slide on the arc groove through the electromagnetic sleeve 540, thereby detecting the wear of the rack. For example, if the rack on one side is severely worn, it means that the rack spacing on both sides increases, and the electromagnetic column 510 moves accordingly. Then the position of the electromagnetic column 510 is detected by the rope encoder. When the displacement of the electromagnetic column 510 is too large, it means that under the condition of long-term unbalanced load, the rack on one side is worn too much, and the staff can be prompted to replace parts through warning structures such as buzzers.

[0060] On the basis of the above embodiment, the movable rack 410 includes a first tooth surface 411 facing the rail body 100 and a second tooth surface 412 away from the rail body 100; the first tooth surface 411 is arranged parallel to the plane where the rail body 100 is located, and the second tooth surface 412 is inclined relative to the plane where the rail body 100 is located; the limiting rack 401 is provided with a first tooth groove surface corresponding to the first tooth surface 411, and a second tooth groove surface is provided corresponding to the second tooth surface 412.

[0061] On the basis of the above embodiment, a driving motor is further installed inside the carrier body 210, and a running wheel 230 is fixedly connected to the rotating shaft end of the driving motor. The running wheel 230 is at least partially located outside the carrier body 210 and is used to abut against the track body 100. By rotating the running wheel 230, the carrier body 210 can be moved along the track body 100.

[0062] Next, to facilitate understanding by those skilled in the art, a power-on self-test method for a track-type conveyor device is also provided in this embodiment, which is applied to the above-mentioned track-type conveyor device, and includes:

[0063] S1. After starting the power supply, keep the electromagnetic locking seat 530 unpowered and power the electromagnetic column 510. At this time, it means that the electromagnetic column 510 can slide on the arc groove through the electromagnetic sleeve 540, so as to detect the wear amount of the rack;

[0064] S2. Detect the position of the electromagnetic column 510 by means of a draw-wire encoder, and determine whether the position of the electromagnetic column 510 exceeds a preset safety value; the safety value may be set to 1 mm, 2 mm, etc., depending on the design parameters of the rack;

[0065] S3, if yes, then sound an alarm through a buzzer to remind the staff to replace the parts;

[0066] S4, if not, the electromagnetic column 510 is powered off and the electromagnetic locking seat 530 is powered on; thereby, the electromagnetic column 510 is positioned and fixed between the two trigger buttons 420, which indicates that the flexible ends 220 on both sides are in a normal working state;

[0067] S5, starting the driving motor to drive the running wheel 230 to perform simulated transportation on the track body 100;

[0068] S6, determining whether the driving motor has stopped rotating; it is understandable that when a dead point occurs, it means that the two ends of the flexible end portions 220 are unbalanced, and at this time, the driving motor is difficult to drive the walking wheel 230 to rotate under the action of external force;

[0069] S7. When the driving motor stops, the staff can remotely control the electromagnetic column 510 on a flexible end 220 to energize, so that the corresponding movable rack 410 moves away from the limit rack 401, and then adjust the position of the movable shell 221 relative to the supporting body 210 through the driving structures such as the lifting cylinder and the lifting motor, so as to achieve the front and rear balance of the two flexible ends 220; as another optional implementation, the staff can also directly press the two trigger buttons 420, and directly drag the movable shell 221 up and down through the trigger buttons 420 to adjust the position of the movable shell 221 relative to the supporting body 210, so as to achieve the front and rear balance of the two flexible ends 220.

[0070] In summary, the above-mentioned track-type conveying device and its power-on self-check method can effectively avoid dead points in the operation of the track-type conveying device, and the structure has strong applicability. Facing various transportation scenarios, the stability of transportation can be ensured after the power-on self-check method is checked.

[0071] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
