The structured transmission station is located at one side of the rejection station, namely, the side of the turnover mechanism 100 facing downwards in an inclined manner, and the structured transmission station comprises a second conveyor belt 102 arranged horizontally.
The conveyor belt cleaning device comprises a connecting piece 200, a first cleaning mechanism and a second cleaning mechanism, wherein one end of the connecting piece 200 is connected with the turnover mechanism 100, the other end of the connecting piece 200 can rotate along with the turnover mechanism 100, the first cleaning mechanism is provided with a first end and a second end, the second cleaning mechanism is provided with a third end and a fourth end, when the connecting piece 200 rotates along with the turnover mechanism 100 from the first position to the second position, the first end is driven to move and abut against the first conveyor belt 101 through the second end, the third end is driven to move and abut against the second conveyor belt 102 through the fourth end, the first end carries out cleaning operation on the first conveyor belt 101, the third end carries out cleaning operation on the second conveyor belt 102, in the embodiment, the first position can be a position where the first conveyor belt 101/turnover mechanism 100 is in a horizontal state, and the second position can be a position where the first conveyor belt 101/turnover mechanism 100 is in an inclined state, the second conveyor 102 is always horizontally disposed.
In a possible implementation manner, referring to fig. 2 and 7, the conveyor belt cleaning device further includes a fixed seat 201, a first hinge point 300 is provided between the first cleaning mechanism and the fixed seat 201, the first end and the second end are respectively disposed at two sides of the first hinge point 300, when the connecting element 200 abuts against and drives the second end to rotate around the first hinge point 300, the first end is driven by the second end to correspondingly rotate around the first hinge point 300 to be in contact with the first conveyor belt 101, so as to clean the first conveyor belt 101; the second hinge point 400 is further arranged between the second cleaning mechanism and the fixing base 201, the third end and the fourth end are arranged on two sides of the second hinge point 400, the connecting piece 200 is abutted to and drives the fourth end to rotate around the second hinge point 400, and the third end is driven by the fourth end to correspondingly rotate around the second hinge point 400 to be in contact with the second conveyor belt 102, so that the second conveyor belt 102 is cleaned.
In a possible implementation manner, referring to fig. 2 and 3, the first cleaning mechanism includes a first connecting rod 301 and a first cleaning member 302, the first connecting rod 301 is hinged to the fixing base 201, that is, the first connecting rod 301 and the fixing base 201 form a lever structure, when the connecting member 200 is located at the first position, the first connecting rod 301 can be in a horizontal state, in this embodiment, a hinge point of the first connecting rod 301 and the fixing base 201 is a first hinge point 300, two ends of the first connecting rod 301 correspond to a first end and a second end of the first cleaning mechanism, respectively, the first cleaning member 302 is detachably mounted at the first end, the second end abuts against a lower end portion of the connecting member 200, when the connecting member 200 rotates with the turnover mechanism 100 from the first position to the second position, the lower end portion of the connecting member 200 drives the second end to rotate downward along the first hinge point 300, at this time, the first end rotates upward along the first hinge point 300 until the first cleaning member 302 abuts against the first conveyor belt 101, first conveyor belt 101 moves relative to first cleaning member 302 such that first cleaning member 302 performs a cleaning operation on first conveyor belt 101.
It can be understood that when the connecting member 200 is at the first position, the connecting member 200 is perpendicular to the horizontal plane, and the connecting member 200 rotates with the turnover mechanism 100 from the first position to the second position, the lower end of the connecting member 200 moves downward to press against the second end, so that the first end tilts along the first hinge point 300 until the first cleaning member 302 abuts against the first conveyor belt 101.
In practice, when the connecting member 200 is at the first position, the first cleaning member 302 is spaced apart from the first conveyor belt 101. When the turnover mechanism 100 drives the connecting member 200 to rotate from the first position to the second position, the connecting member 200 contacts with the second end of the first link 301 and drives the first link 301 to move circumferentially along the first hinge point 300, and when the connecting member 200 is at the second position, the first cleaning member 302 contacts with the first conveyor belt 101 to clean the first conveyor belt 101. When the turnover mechanism 100 drives the connection member 200 to return from the second position to the first position, the connection member 200 is separated from the second end of the first link 301, so that the first end of the first link 301 rotates downward along the first hinge point 300 due to its own gravity to gradually get away from the first conveyor belt 101, that is, the first cleaning member 302 gets away from the first conveyor belt 101.
In a possible implementation manner, the first hinge point 300 is located near the second end, the first link 301 and the fixing base 201 form an unequal arm lever structure, and the moment arm corresponding to the first end is greater than the moment arm corresponding to the second end, so that after the connecting element 200 is separated from the second end, the first end is convenient to be away from the first conveyor belt 101, that is, the first cleaning element 302 is convenient to be separated from the first conveyor belt 101.
In one possible implementation manner, referring to fig. 4, the first cleaning mechanism may further include a first weight 303 and a limiting member 304. The first weight member 303 may be disposed at the first end, and when the reverse movement mechanism drives the connecting member 200 to rotate from the second position to the first position, the first end is far away from the first conveyor belt 101 under the gravity of the first weight member 303, that is, the first cleaning member 302 can be quickly far away from the first conveyor belt 101. The limiting member 304 is disposed on the fixing base 201 and can abut against the periphery of the first connecting rod 301, and the limiting member 304 can be a rigid member or an elastic member, which can prevent the second end from touching the first conveyor belt 101 during the resetting process, so as to prevent damage to the first conveyor belt 101 or the silicon wafer on the first conveyor belt 101.
In one embodiment, the limiting member 304 is a rigid member. The limiting member 304 may be disposed on the fixing base 201, and the limiting member 304 is located at an included angle between the first end and the fixing base 201, when the connecting member 200 is reset to the first position along with the turnover mechanism 100 from the second position, the lower end of the connecting member 200 cancels the pressure on the second end, and the first end may rotate downward along the first hinge point 300, and the limiting member 304 may limit the downward rotation stroke of the first end, so as to prevent the first weight block 303 from directly impacting the fixing base 201.
For example, the position-limiting member 304 may be made of a rigid material such as metal or plastic.
In another embodiment, the limiting member 304 is an elastic member, one end of the limiting member 304 is connected to the fixing base 201, and the other end is connected to the second end. The both ends of locating part 304 are detachably established respectively on fixing base 201 and first connecting rod 301, can change the elastic component regularly like this to prevent that the elastic component from taking place incomplete elastic deformation back, can't carry on spacingly to first connecting rod 301, make first connecting rod 301 collide first conveyer belt 101 at the in-process that resets.
For example, the stopper 304 may be a compression spring.
In a possible implementation manner, when the first connecting rod 301 and the fixing base 201 form an unequal-arm lever structure, only the limiting member 304 may be disposed on the fixing base 201 without the first balancing weight 303. The limiting member 304 may be a rigid member or an elastic member. The specific positions of the limiting members 304 are the same as those described above, and are not described herein again.
In another possible implementation manner, referring to fig. 5, the first cleaning mechanism includes a second link 305, a second cleaning member 306 and a second weight block 307, and two ends of the second link 305 correspond to two ends of the first cleaning mechanism, respectively. The second link 305 includes a first portion and a second portion of unequal length, with an included angle therebetween. The first end of the second connecting rod 305 is located at the first portion and detachably connected to the second cleaning member 306, the second weight block 307 is disposed at the second end of the second connecting rod 305, the second end of the second connecting rod 305 is located at the second portion, and the second connecting rod 305 is rotatably connected to the fixing base 201. In this embodiment, the second portion is in a vertical state when not stressed due to the gravity of the second weight block 307, and an included angle is formed between the first portion and the second portion, at this time, the first end and the second cleaning member 306 are located above the second weight block 307 and are not on a vertical axis coinciding with the second portion, when the turnover mechanism 100 drives the connecting member 200 to rotate from the first position to the second position, the connecting member 200 makes a circular motion along the rotation center of the turnover mechanism 100, at this time, the lower end of the connecting member 200 horizontally presses the second end or the second weight block 307, drives the second connecting rod 305 to rotate along a hinge point between the second connecting rod and the fixed seat 201, at this time, the first end and the second cleaning member 306 rotate to the vertical direction and abut against the first conveyor belt 101, and further cleans the first conveyor belt 101. When the turnover mechanism 100 drives the connecting member 200 to return from the second position to the first position, since the second end of the second connecting rod 305 has the second weight block 307, the second portion of the second connecting rod 305 returns to be in a vertical state under the action of the gravity of the second weight block 307, and the first portion of the second connecting rod 305 is far away from the first conveyor belt 101, that is, the second cleaning member 306 is far away from the first conveyor belt 101.
In a possible implementation manner, referring to fig. 6 to 9, the second cleaning mechanism includes a third connecting rod 401, a fourth connecting rod 402, and a third cleaning member 403, one end of the third connecting rod 401 is hinged to the fourth connecting rod 402, the other end of the third connecting rod 401 is hinged to the connecting member 200, the third cleaning member 403 is detachably disposed at the other end of the fourth connecting rod 402, the middle portion of the fourth connecting rod 402 is hinged to the fixing base 201, the hinge point between the fourth connecting rod 402 and the fixing base 201 is a second hinge point 400, the third end is the end of the fourth connecting rod 402 where the third cleaning member 403 is disposed, and the fourth end is the end of the third connecting rod 401 that is hinged to the connecting member 200. When the turnover mechanism 100 performs a turnover action, the third connecting rod 401 is driven by the connecting member 200 to move, so that the fourth connecting rod 402 rotates along the second hinge point 400, the third end is close to and abutted against the second conveyor belt 102, that is, the third cleaning member 403 is abutted against the second conveyor belt 102, so as to clean the second conveyor belt 102.
Fig. 9 is a perspective view showing the second cleaning mechanism, and the third link 401 and the fourth link 402 are both linear in shape. One end of the third connecting rod 401 and one end of the fourth connecting rod 402 are rotatably connected, the other end of the third connecting rod 401 is connected with the connecting piece 200, the other end of the fourth connecting rod 402 is detachably connected with the third cleaning piece 403, and the fourth connecting rod 402 is rotatably connected with the fixing seat 201.
In practice, when the connecting member 200 is in the first position, there is a gap between the third cleaning member 403 and the second conveyor belt 102. When the turnover mechanism 100 drives the connecting member 200 to rotate from the first position to the second position, the connecting member 200 drives the third connecting rod 401 to move linearly, and then the third connecting rod 401 drives the fourth connecting rod 402 to move circularly along the second hinge point 400, so that the third cleaning member 403 contacts with the second conveyor belt 102 to clean the second conveyor belt 102.
Specifically, as shown in fig. 2 and fig. 7, the regular transmission station is a downstream station of the rejecting station, in this embodiment, the rejecting station is illustrated on the left side of the regular transmission station, one end of the connecting element 200 is disposed on the turnover mechanism 100, the other end of the connecting element extends downward along the vertical direction, the first cleaning mechanism is disposed on the left side of the connecting element 200, the second cleaning mechanism is disposed on the right side of the connecting element 200, when the turnover mechanism 100 drives the connecting element 200 to rotate from the first position to the second position, the connecting element 200 drives the second end of the first connecting rod 301 to rotate downward along the first hinge point 300, the first end of the first connecting rod is rotated upward along the first hinge point 300 to abut against the first conveyor belt 101, so as to clean the first conveyor belt 101, the connecting element 200 drives the third connecting rod 401 to move linearly to the left, and the third connecting rod 401 drives the fourth connecting rod 402 to rotate along the second hinge point 400, and the third end rotates upward along the second hinge point 400 to abut against the second conveyor belt 102, thereby cleaning the second conveyor belt 102. When the turnover mechanism 100 drives the connecting member 200 to rotate from the second position to the first position, the lower end of the connecting member 200 releases the pressure on the first connecting rod 301, the first end of the connecting member rotates downward to be away from the first conveyor belt 101 due to the self-gravity, the third connecting rod 401 is driven by the connecting member 200 to move linearly rightward, the third connecting rod 401 drives the fourth connecting rod 402 to rotate along the second hinge point 400, and the third end of the connecting member rotates downward to be away from the second conveyor belt 102 along the second hinge point 400.
In one embodiment, the fixing base 201 may be fixedly disposed on the conveying device.
In one possible implementation, each of the first cleaning member 302, the second cleaning member 306 and the third cleaning member 403 can be a relatively soft article having a cleaning function. For example, the first cleaning member 302, the second cleaning member 306 and the third cleaning member 403 may be sponges or rags.
