[0002] In existing equipment equipped with linear motors, cross-belt sorting systems using linear motors often experience situations where screws, tools, etc., fall off due to reasons such as vibration or installation errors and cannot be detected in time. Eventually, these items are attracted to the permanent magnet mover when the transmission line moves, which may cause the permanent magnet mover to collide with the motor body, resulting in machine downtime and hardware damage. Furthermore, when the height difference between the permanent magnet mover and the linear motor exceeds the safe distance, a protection mechanism is needed to stop the equipment and prevent further damage. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that: when a linear motor is running, it may attract foreign objects, causing the foreign objects attracted under the permanent magnet to collide with the motor.

[0004] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes an anti-collision mechanism, which includes an anti-collision unit, the anti-collision unit including an anti-collision bracket, an anti-collision plate and a reset component, the anti-collision bracket and the anti-collision plate being movably connected, and the reset component being disposed on the anti-collision bracket.

[0005] In a preferred embodiment of the anti-collision mechanism of the present invention: the anti-collision bracket includes a side wall, a connecting shaft and a fixing plate. The anti-collision bracket is a horizontal C-shape. The fixing plate is disposed between the side walls. The side walls are right-angled trapezoids.

[0009] In a preferred embodiment of the anti-collision mechanism of the present invention: the anti-collision plate includes a side plate, an oblique anti-collision plate, a baffle and a connecting arm, the side plate is vertically arranged, the baffle is horizontally arranged, the oblique anti-collision plate is arranged between the side plate and the baffle, and the connecting arm is arranged on both sides of the anti-collision plate.

[0010] In a preferred embodiment of the anti-collision mechanism of the present invention: the oblique angle of the oblique impact plate is between 30° and 60°.

[0011] In a preferred embodiment of the anti-collision mechanism of the present invention: the baffle includes a first baffle and a second baffle spaced apart, and the space between the first baffle and the second baffle is M.

[0012] In a preferred embodiment of the anti-collision mechanism of the present invention: the arm connecting hole on the connecting arm is connected to the shaft hinge.

[0013] In a preferred embodiment of the anti-collision mechanism of the present invention: the reset component includes a limiting rod and an elastic element, the limiting rod is disposed on a fixed plate, the bottom end of the elastic element is disposed on the fixed plate, the elastic element is sleeved on the limiting rod, and the height of the elastic element is greater than the height of the limiting rod.

[0015] The beneficial effects of this invention are as follows: when the top sorting component adsorbs foreign objects during operation, it will first contact the inclined impact plate. The height of the elastic element is greater than the height of the limit rod. The elastic element resists the impact of foreign objects, thereby protecting the linear motor. The fixed plate will limit the rotation angle of the baffle, and the elastic element will reset the anti-collision plate.

[0016] Another objective of this invention is to provide a protective device that addresses the need for a way to stop the equipment and prevent further damage when the height difference between the permanent magnet actuator and the linear motor exceeds a safe distance.

If the top picking component accidentally attracts foreign objects during operation and is below the safe distance, it will first contact the inclined impact plate to resist the impact of the foreign objects, thereby protecting the linear motor. The micro switch set can make the equipment stop suddenly during operation. Attached Figure Description

[0029] Example 1

[0030] Reference Figure 1 This embodiment provides an anti-collision mechanism, including an anti-collision unit 100. Specifically, the anti-collision unit 100 includes an anti-collision bracket 101, an anti-collision plate 102, and a reset component 103. The anti-collision bracket 101 and the anti-collision plate 102 are movably connected, and the reset component 103 is disposed on the anti-collision bracket 101.

[0031] In use, the anti-collision bracket 101 and the anti-collision plate 102 are movably connected. When the anti-collision plate 102 comes into contact with the impacting foreign object, the anti-collision plate 102 rotates around the arm connection hole on its connecting arm. When the anti-collision plate 102 rotates to a certain angle, it contacts the reset component 103 and stops rotating. Before the anti-collision plate 102 stops, the elastic element buffers the anti-collision plate to reduce vibration.

[0032] Example 2

[0033] In one embodiment provided in this application, the anti-collision bracket 101 includes a side wall 101a, a connecting shaft 101b, and a fixing plate 101c. The anti-collision bracket 101 is a horizontal C-shape. The fixing plate 101c is disposed between the side walls 101a. The side walls 101a are right-angled trapezoids. The connecting shaft 101b is disposed on the side of the fixing plate 101c and close to the hypotenuse of the trapezoid. In this embodiment, the connecting shaft 101b and the fixing plate 101c are at the same horizontal height.

[0034] Furthermore, the sidewalls 101a are symmetrically arranged, and a connecting hole 101a-1 is provided on the sidewalls 101a. The connecting shaft 101b is disposed in the connecting hole 101a-1. The connecting shaft 101b includes a first limiting head 101b-1 and a shaft body 101b-2. The first limiting head 101b-1 is disposed at both ends of the shaft body 101b-2. The fixing plate 101c includes a first L-shaped part 101c-1, a second L-shaped part 101c-2, and a limiting hole 101c-3. The limiting hole 101c-3 is disposed near both ends of the fixing plate 101c. The first L-shaped part 101c-1 and the second L-shaped part 101c-2 are disposed between the symmetrically arranged limiting holes 101c-3. The second L-shaped part 101c-2 is disposed on one side of the first L-shaped part 101c-1.

[0035] Preferably, the anti-collision plate 102 includes a side plate 102a, an inclined anti-collision plate 102b, a baffle 102c, and a connecting arm 102d. The side plate 102a is vertically arranged, the baffle 102c is horizontally arranged, the inclined anti-collision plate 102b is arranged between the side plate 102a and the baffle 102c, the inclined anti-collision plate 102b is adapted to the inclined side of the side wall, and the connecting arm 102d is arranged on both sides of the anti-collision plate 102.

[0036] Furthermore, the angle of the inclined impact plate 102b is between 30° and 60°. In this embodiment, the angle of the inclined impact plate 202b is preferably 45°. The inclined surface has a certain buffering effect. The sorting component reaches a speed of 2m / s during operation. If a vertical surface is used, a strong impact will occur, which will cause secondary damage to the equipment.

[0037] Furthermore, the baffle 102c includes a first baffle 102c-1 and a second baffle 102c-2 spaced apart, and the space between the first baffle 102c-1 and the second baffle 102c-2 is M.

[0038] Furthermore, the arm connection hole 102d-1 on the connecting arm 102d is hinged to the shaft 101b-2, that is, the anti-collision plate 102 and the anti-collision bracket 101 rotate around the arm connection hole 102d-1 and the shaft 101b-2.

[0039] Preferably, the reset assembly 103 includes a limiting rod 103a and an elastic element 103b. The limiting rod 103a is disposed on the fixed plate 101c, and the bottom end of the elastic element 103b is disposed on the fixed plate 101c. The elastic element 103b is sleeved on the limiting rod 103a. The height of the elastic element 103b is greater than the height of the limiting rod 103a. When the anti-collision plate 102 is not under force, the top end of the elastic element 103b is located on the bottom side of the baffle 102c.

[0040] Furthermore, a second limiting head 103a-1 is provided at the bottom end of the limiting rod 103a, and the second limiting head 103a-1 causes the limiting rod 103a to be set on the fixing plate 101c through the limiting hole 101c-3.

[0041] When in use, the top of the elastic element 103b is located on the bottom side of the baffle 102c when the anti-collision plate 102 is not under force. When the anti-collision plate 102 is impacted, the anti-collision plate 102 and the anti-collision bracket 101 rotate around the arm connection hole 102d-1 and the shaft 101b-2. During the rotation of the anti-collision plate 102, the elastic element 103b has a buffering effect on the anti-collision plate 102. The elastic coefficient of the elastic element 103b is calculated based on the maximum impact force. The elastic element 103b is existing technology and will not be described in detail here. The height of the elastic element 103b is greater than the height of the limiting rod 103a. When the anti-collision plate 102 rotates to a certain angle, it is restricted by the limiting rod 103a and cannot continue to rotate.

[0042] Example 3

[0043] In one embodiment provided in this application, a protective device is further provided, including a protective unit 200. The protective unit 200 includes a laser sensor 201 and a micro switch 202. The laser sensor 201 is disposed on a first L-shaped member 101c-1, and the micro switch 202 is disposed on a second L-shaped member 101c-2. The laser of the laser sensor 201 passes through the partition space M.

[0044] Specifically, in this embodiment, the preferred laser sensor 201 is model WTT4SLC-3B2262A00. Its function is to prioritize sensing the height difference h1 between the bottom of the sorting component and the linear motor. In this embodiment, the height difference h1 is 4-6mm.

[0045] Specifically, the height difference between the top side of the baffle 102c and the top side of the linear motor is h2, and in this embodiment, the height difference h2 is 2mm.

[0046] Specifically, in this embodiment, the preferred micro switch model is Omron 202SS-01GL2.

[0047] In use, the protective unit 200 is installed at both ends of the linear motor, and the laser sensor 201 is installed in the interval space M. The height difference between the sorting component and the linear motor is h1, and the height difference between the linear motor and the top surface of the baffle 102c is h2. When the height of the sorting component exceeds the safe distance, the laser sensor 201 emits a signal to the electronic control to realize emergency power cut-off. The above steps are existing technology. When the bottom of the sorting component adsorbs foreign objects, if the height of the foreign objects is greater than h1-h2, the foreign objects will be in rigid contact with the inclined impact plate 102b. The anti-collision bracket 101 and the anti-collision plate 102 are connected to the shaft 1 via the arm connection hole 102d-1. 01b-2 is the rotation of the axis. At this time, the micro switch 202 is squeezed by the anti-collision plate 102. The micro switch 202 sends a signal to make the running equipment stop suddenly to protect the equipment. The above steps are the prior art. During the rotation of the anti-collision plate 102, the elastic element 103b has a buffering effect on the anti-collision plate 102. The height of the elastic element 103b is greater than the height of the limit rod 103a. When the anti-collision plate 102 rotates to a certain angle, it is restricted by the limit rod 103a and cannot continue to rotate, thereby protecting the micro switch 202. The elastic element 103b can also reset the anti-collision plate 102 multiple times when it is not under force.

[0048] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
