DETAILED DESCRIPTION
[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0026] See also Figures 1 to 10 As shown, the present invention provides a technical solution: an AGV trolley for loading and unloading materials, comprising a flip assembly 1, a transmission assembly 2, a control assembly 3, a shell assembly 4 and an adjustment assembly 5, wherein the shell assembly 4 comprises a base 404, an inner bracket 403 is fixedly mounted on the base 404, the flip assembly 1 comprises a buffer link 103, a rack 104 and a one-way gear 106, the second end of the buffer link 103 is slidably connected to the inner bracket 403, the inner bracket 403 is provided with a slide groove, the buffer link 103 is provided with a spring, the rack 104 is provided with a one-way tooth, through the one-way tooth Engaged with the one-way gear 106, the transmission assembly 2 includes a supporting slide 201, and a long connecting rod 203 is rotatably connected to the second end of the supporting slide 201. The control assembly 3 includes an upper connecting rod 301, and the upper connecting rod 301 is rotatably connected to the second end of the long connecting rod 203. The upper connecting rod 301 is rotatably connected to a connecting block 302, and the connecting block 302 is slidably connected to the long sliding rod 303. The adjustment assembly 5 includes a swivel 502 and a rope 503, and the first end of the rope 503 is fixedly connected to the swivel 502, and the swivel 502 is rotatably connected to the first end of the long connecting rod 203.
[0027] The flip assembly 1 also includes a main driving rod 102 and a limiting block 107. The first end of the main driving rod 102 is fixedly connected to the output shaft of the motor 101, and the motor 101 is fixedly installed on the base 404. The second end of the main driving rod 102 is rotatably connected to a one-way gear 106. The limiting block 107 is rotatably connected to a bracket on the base 404, and a torsion spring is arranged on the limiting block 107.
[0028] The second end of the rack 104 slides on the second end of the main driving rod 102, the first end of the rack 104 is fixedly connected to the support plate 401, the first end of the buffer link 103 is rotatably connected to the support plate 401, and the second end of the buffer link 103 is also slidably connected to the second end of the main driving rod 102.
[0029] One end of the spring on the buffer link 103 is fixedly connected to the first end of the buffer link 103, and the other end of the spring is fixedly connected to the second end of the main driving rod 102. The first end of the auxiliary driving rod 108 is also fixedly connected to the output shaft of the motor 101, and the second end of the auxiliary driving rod 108 is fixedly connected to the auxiliary driving slider 105. The auxiliary driving slider 105 is provided with a multi-stage arc-shaped slider, and the second end of the auxiliary driving rod 108 is fixed to an innermost arc-shaped slider of the auxiliary driving slider 105. The rotation of the auxiliary driving rod 108 pushes the extension of the multi-stage arc-shaped slider on the auxiliary driving slider 105. When the innermost arc-shaped slider of the auxiliary driving slider 105 contacts the support plate 401, the auxiliary driving slider 105 will push the support plate 401 when it moves.
[0030] like Figure 3 , Figure 4 and Figure 5 As shown, when in use, the material is placed on the support plate 401, and the support plate 401 squeezes the buffer link 103 and the rack 104 by the gravity of the material, and the second end of the buffer link 103 slides on the main driving rod 102, and squeezes the spring of the buffer link 103, thereby buffering the support plate 401. When the rack 104 moves downward, the one-way teeth on the rack 104 push the one-way gear 106 to rotate counterclockwise, and the one-way gear 106 pushes the limiting block 107 to rotate. The limiting block 107 is reset by the torsion spring, and the limiting block 107 limits the one-way gear 106 to rotate clockwise, so that the rack 104 can only move downward, not upward.
[0031] When placing materials, the support plate 401 squeezes the spring on the buffer link 103, and the support plate 401 will rock back and forth up and down under the action of the spring. The restriction of the limiting block 107 can reduce this rocking and stabilize the materials, thereby preventing the materials from moving on the support plate 401 due to the rocking of the spring when the trolley is conveying materials, especially when the trolley is accelerating or decelerating.
[0032] Because there is a large gap between the one-way gear 106 and the teeth on the rack 104, the rack 104 has a small up and down movement, so that when the trolley accelerates or decelerates, a certain buffering capacity is retained and large shaking is avoided. If the material moves too much and hits the upper side plate 406, it will affect the movement route of the trolley. If the material is large in size, it may directly fly out of the support plate 401.
[0033] When the motor 101 is started, the main driving rod 102 is driven to rotate. The main driving rod 102 pushes the buffer link 103 and the support plate 401 through the spring on the buffer link 103, so that the support plate 401 rotates around the axis at the other end. When the support plate 401 and the main driving rod 102 rotate, the rack 104 and the one-way gear 106 are driven to move, so that the one-way gear 106 is separated from the limiting block 107, and the limiting block 107 is no longer restricted. The one-way gear 106 can rotate clockwise, and the rack 104 can also move upward, so that the rack 104 can be reset, which is convenient for buffering when reloading materials. The auxiliary driving slider 105 only pushes the support plate 401 when the material on the support plate 401 is very heavy, so that the spring on the buffer link 103 is severely squeezed, so that the support plate 401 contacts the auxiliary driving slider 105. At this time, the starting motor 101 will cause the auxiliary driving slider 105 to push the support plate 401. Two unloading methods are used to avoid a single method causing a large load on the parts.
[0034] The transmission assembly 2 also includes a supporting slide 201, a first end of the supporting slide 201 is rotatably connected to the supporting plate 401, a first end of a first torsion spring 202 is fixedly connected to the second end of the supporting slide 201, a second end of the first torsion spring 202 is fixedly connected to a long connecting rod 203, a second end of the long connecting rod 203 is rotatably connected to a reset sleeve rod 204, a first end of a reset spring 205 is fixedly connected to the reset sleeve rod 204, a second end of the reset spring 205 is fixedly connected to the supporting slide 201, and the supporting slide 201 is also slidably connected to a bracket of a base 404.
[0035] like Fig. 9 and Fig.10 As shown, when in use, when the support plate 401 rotates, the first end of the long connecting rod 203 is pulled by the rope 503, so that the long connecting rod 203 rotates around the axis of the second end of the supporting slide plate 201, and twists the first torsion spring 202. The second end of the long connecting rod 203 drives the reset sleeve 204 to squeeze the reset spring 205 downward. After unloading is completed, the reset sleeve 204 is pushed upward by the reset spring 205, driving the first end of the long connecting rod 203 to reset.
[0036] The control assembly 3 further comprises a telescopic rod 308, a first end of which is rotatably connected to the upper connecting rod 301, a second end of which is rotatably connected to the lower connecting rod 307, the lower connecting rod 307 is rotatably connected to the supporting slide plate 201, the lower connecting rod 307 is also rotatably connected to the right connecting rod 306, the second end of the long sliding rod 303 is fixedly connected to the right connecting rod 306, the first end of the long sliding rod 303 is fixedly connected to the first end of the upper spring 304, the second end of the upper spring 304 is fixedly connected to the connecting block 302, the connecting block 302 is also fixedly connected to the first end of the lower spring 305, the second end of the lower spring 305 is fixedly connected to the right connecting rod 306. The connecting block 407 is fixedly connected to the upper connecting rod 301.
[0037] like Fig.10 As shown, during loading, the support plate 401 is moved downward by the material, pushing the support slide plate 201 to move downward, and the support slide plate 201 and the long connecting rod 203 drive the lower connecting rod 307 and the upper connecting rod 301 to move downward.
[0038] When the support plate 401 rotates, because of the rope 503 and the second torsion spring 501, the long connecting rod 203 will not rotate immediately. When the rope 503 is straightened, the second end of the long connecting rod 203 will rotate clockwise, pushing the upper connecting rod 301 to follow the long connecting rod 203 to rotate clockwise. After the upper connecting rod 301 moves, the rotation centers of the upper connecting rod 301 and the lower connecting rod 307 are offset and no longer aligned. Because the lower connecting rod 307 is fixed on the supporting slide plate 201, the upper connecting rod 301 drives the first end of the telescopic rod 308, and the second end of the telescopic rod 308 rotates on the lower connecting rod 307, and the upper connecting rod 301 pushes the first end of the long sliding rod 303 through the connecting block 302, so that the second end of the long sliding rod 303 drives the connecting rod 306 to rotate on the lower connecting rod 307.
[0039] Because the friction force of the telescopic rod 308 is equal to the elastic force of the upper spring 304 and the lower spring 305, the upper connecting rod 301 rotates with the long connecting rod 203, and the telescopic rod 308 and the connecting rod 306 rotate on the lower connecting rod 307. The upper connecting rod 301 and the lower connecting rod 307 remain horizontal, while the lower spring 305 is squeezed, the upper spring 304 is stretched, and the long sliding rod 303 slides on the baffle 402, so that the baffle 402 remains vertical and rotates with the upper sliding rod 303. The rotation trajectory of the baffle 402 is an arc, thereby avoiding the interference of the right-angle side of the support plate 401. The large spring 309 is pulled by the support block 407 fixed on the upper connecting rod 301, and the baffle 402 is driven to move downward by the large spring 309. Finally, the horizontal height of the upper end of the baffle 402 is lower than the edge of the upper panel of the support plate 401, so that the material slides off the support plate 401.
[0040] After the unloading is completed, the upper connecting rod 301 is driven to return to its original position by the upper spring 304 and the lower spring 305, and the baffle 402 is driven to return to its original position by the large spring 309.
[0041] The housing assembly 4 also includes a support plate 401, to which a baffle 402 is movably connected, to which a first end of a large spring 309 is fixedly connected, and a second end of the large spring 309 is fixedly connected to a support block 407, and the support block 407 is rotatably connected to the long connecting rod 203.
[0042] The housing assembly 4 further includes an upper side plate 406 , which is fixedly connected to the support plate 401 , and a surrounding plate 405 is also fixedly connected to the base 404 .
[0043] The adjustment assembly 5 further includes a second torsion spring 501 , a first end of which is fixedly connected to the swivel 502 , a second end of which is fixedly connected to the long connecting rod 203 , and a second end of the rope 503 is fixedly connected to the support plate 401 .
[0044] When the support plate 401 rotates, the second end of the rope 503 is pulled, and the first end of the rope 503 pulls the swivel 502 to rotate on the long connecting rod 203, and at the same time drives the second torsion spring 501 to twist. When the rope 503 is straightened, the support plate 401 continues to rotate, which drives the long connecting rod 203 to rotate, and then controls the baffle 402 to move downward for unloading. By setting the length of the rope 503, the angle at which the support plate 401 rotates is controlled before the baffle 402 begins to fall, so that the materials can slide toward the baffle 402 before falling, gather at the baffle 402, and then unload together, so as to avoid the support plate 401 rotating too fast during unloading, so that some lighter materials fly out directly, or some heavier materials fall from a high place and are damaged.
[0045] During operation, the material is first placed on the support plate 401. The support plate 401 moves downward due to the gravity of the material, and is buffered by the spring on the buffer link 103. The support plate 401 is restricted by the limit block 107, the one-way gear 106 and the rack 104, and then shakes up and down greatly. During unloading, the buffer link 103 is lifted by the main driving rod 102, and the limit block 107 is away from the one-way gear 106 to release the restriction. At the same time, the support plate 401 pulls the rope 503 to drive the swivel 502 to rotate. After the rope 503 is straightened, the first end of the long connecting rod 203 is pulled through the swivel 502 to rotate the long connecting rod 203. The second end of the long connecting rod 203 controls the upper connecting rod 301 to rotate clockwise, and the baffle 402 is pulled down by the support block 407 and the large spring 309, thereby opening the unloading port, and the material slides down to complete the unloading.
