DETAILED DESCRIPTION

[0033] To make the purpose, technical scheme and advantages of the present application more clear and understandable, the present application will be further described in detail below with specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0034] Referring to Figures 1 to 10 , the tray feeding mechanism of the present application mainly comprises a body 100, which is a square frame body. Four areas are arranged on the body 100, one of which is a transfer area 130, one is a conveying area 120, one is a feeding area 110, and the other is a recovery area 140. The functions of these four areas are consistent with those of the prior art, and will not be described in detail. The difference lies in the structural arrangement, which is different from the prior art. Specifically, as shown in Figure 1 , the transfer area 130, the conveying area 120 and the recovery area 140 are arranged in sequence along the first straight line 200, i.e. in the left-right direction as shown in Figure 1 , and the feeding area 110 and the conveying area 120 are arranged in sequence along the second straight line 300, i.e. in the front-back direction as shown in Figure 1The vertically spaced arrangement shown has the first straight line 200 and the second straight line 300 intersecting, preferably as follows: Figure 1 As shown, it is vertical. That is to say, as... Figure 1 As shown, with the left-right direction of the machine body 100 as its length and the up-down direction as its width, the feeding area 110 and the conveying area 120 are arranged along the width direction of the machine body 100, while the transfer area 130, the conveying area 120, and the recovery area 140 are arranged along the length direction of the machine body 100. Alternatively, the feeding area 110 and the conveying area 120 can be arranged at an angle to the width direction of the machine body 100 instead of being along its width. This design reduces the overall length of the equipment, thereby reducing the space occupied by the equipment in the production line aisle, ensuring the safety of the production line, and improving operability.

[0035] In this embodiment, the feeding area 110 is equipped with a feeding mechanism 10. Specifically, as shown below... Figures 2 to 4 As shown, the feeding mechanism 10 includes a first slide rail 11, a first slider 12, a first slide block 13, a first support plate 15, a first drive component 16, a lifting rod, and a lifting drive component 14. A material feeding mechanism 10 is provided on the bottom plate surface of the machine body 100 along... Figure 2The front-rear direction shown is also the direction in which the base (not shown) of the machine body 100 extends, and the two second sliding rails 21 are arranged opposite and spaced apart on the left and right sides of the base in the width direction of the machine body 100, i.e., along the second straight line 300. At least one (one in the example) first sliding block 12 is slidably arranged on each first sliding rail 11, and a plate-shaped first sliding seat 13 extending along the second straight line 300 is arranged on the first sliding block 12. Two left and right opposite and spaced-apart lifting drives 14, such as pneumatic cylinders, are arranged at the top end of the sliding seat, and the driving end of each lifting drive 14 extends vertically. A vertically extending lifting rod (not shown) is arranged at the top end of each lifting drive 14, and a long plate-shaped first support plate 15 extending along the second straight line 300 is fixed to the top end of each lifting rod. A first drive 16, which is exemplarily a hydraulic cylinder, is fixed to the side of one of the first sliding rails 11 and has a driving end that extends and retracts along the second straight line 300. The driving end of the first drive 16 is connected to the first sliding seat 13 so that when the first sliding seat 13 extends and retracts along the second straight line 300 or the extension direction of the second sliding rail 21, the first sliding seat 13 drives the first sliding seat 13 to move back and forth along the second straight line 300 towards or away from the conveying area 120. The top end surface of the first support plate 15 is implemented as a first support surface 151. In this embodiment, the first support surface 151 is not a flat surface, but is implemented as a structure in which the two ends protrude upwards and the middle is concave downwards, so that when the first sliding seat 13 drives the first support plate 15 to move along the extension direction of the first sliding rail 11, i.e., along the second straight line 300, the tray on the first support surface 151 will not fall off the first support plate 15 due to inertia. As a preferred embodiment, a support plate block (not shown) in the shape of an inverted L is additionally arranged in the middle of the two first support plates 15 and is fixed to the base to improve the support effect. It should be noted that in this embodiment, the new material trays are arranged in a stacked manner on the first support plate 15 in the replenishment area 110, and the height of the first support plate 15 is adjusted by driving the lifting drives 14. When the number of new material trays on the first support plate 15 is large, the height of the first support plate 15 can be adjusted to facilitate the operator to move the new material trays on the first support plate 15 to the top end position of the conveying area 120. When the number of new material trays on the first support plate 15 is small, i.e., the lifting drives 14 cannot lift the trays on the first support plate 15 to a position that is convenient for moving to the top end position of the conveying area 120, the first drive 16 can be used to drive the first support plate 15 to move along the extension direction of the first sliding rail 11 or along the second straight line 300 towards the bottom end of the conveying area 120, thereby facilitating the operator to move the new material trays on the first support plate 15 to the bottom end position of the conveying area 120, and then lifting the new material trays from the bottom end position of the conveying area 120 to the top end position of the conveying area 120.That is to say, in the embodiment, the conveying area 120 has two receiving replenishment positions, one is a receiving replenishment top end position, and the other is a receiving replenishment bottom end position, that is, the material tray can be directly received from the top receiving replenishment area 110, or the material tray can be received from the bottom receiving replenishment area 110, which is specifically determined according to the stacking number or height of the material tray of the replenishment area 110. The flexibility of replenishment is improved.

[0036] For the conveying area 120, as shown in Figure 3 and Figure 5 , the conveying area 120 is provided with a conveying mechanism 20. Since the conveying area 120 has two positions for receiving the new material tray of the replenishment area 110, one is the top end, and the other is the bottom end, in the embodiment, the conveying mechanism 20 can be vertically lifted so that when the bottom end receives replenishment, it can be lifted to the top end to facilitate the horizontal movement of the new material tray to the transfer area 130, that is, the receiving top end position of the conveying area 120 is at the same horizontal plane as the transfer area 130. Specifically, as shown in Figure 5 , the conveying mechanism 20 includes a second sliding rail 21, a second sliding block, a second sliding seat 22, a second support plate 23, a first driving rod 24, and a second driving member 25. Two second sliding rails 21 are oppositely and spacedly arranged on the inner rear side wall surface of the machine body 100 and extend vertically from the bottom end to the top end of the inner rear side wall surface of the machine body 100. At least one (exemplarily one) second sliding block is slidably connected on any second sliding rail 21. The second sliding seat 22 is fixed on the second sliding block and extends horizontally towards the replenishment area 110, and the second support plate 23 is a horizontal plate and is fixed on the second sliding seat 22, and the size is preferably slightly larger than the size of the tray. The first driving rod 24 extends vertically and is rotatably arranged between the two second sliding rails 21. The driving end of the second driving member 25 is downwardly and drivingly connected with the first driving rod 24, such as through a transmission belt or chain, and in the embodiment, the second driving member 25 is preferably a conventional servo motor.

[0037] For the transfer area 130, in the embodiment, the transfer area 130 has a first end adjacent to the conveying area 120, specifically the receiving top end position of the conveying area 120, that is, the right end as shown in Figure 1 , and a second end away from the conveying area 120, specifically the receiving top end position of the conveying area 120, that is, the left end as shown in Figure 1 . Similarly, the transfer area 130 is provided with a transfer mechanism 30. For the transfer mechanism 30, as shown in Figures 6 to 10, including the first interface component 31 and the second interface component 32, the first interface component 31 and the second interface component 32 can reciprocate switch at the first end and the second end, that is, at the first time, such as the initial time, the first interface component 31 is at the first end and the second interface component 32 is at the second end, at the next time, the first interface component 31 is at the second end and the second interface component 32 is at the first end, at the next time, the first interface component 31 returns to the first end and the second interface component 32 returns to the second end, and so on. In order to realize the reciprocating switching of the first interface component 31 and the second interface component 32, the embodiment is realized as follows, as shown in Figure 5 , the first interface component 31 includes the first fixed plate 311, the third sliding rail 312, the third sliding block 313, the third support plate 314 and the third driving piece 315. Specifically, two first fixed plates 311 are arranged oppositely and spaced along the second straight line 300 direction, that is, the up-down direction as shown in Figure 1 or the front-rear direction as shown in Figure 2 , and extend along the first straight line 200 direction, that is, the left-right direction as shown in Figure 1 , the top end of any first fixed plate 311 is fixed with the third sliding rail 312, the extension direction of the third sliding rail 312 is consistent with the first fixed plate 311, that is, extends along the first straight line 200 direction, at least one third sliding block 313 (exemplarily two) is slidably arranged on any third sliding rail 312, the third support plate 314 is a quadrilateral plate and is fixed horizontally on the third sliding block 313, in order to realize the fixation of the tray, four L-shaped limiting blocks (not marked) are arranged on the third support plate 314, the four limiting blocks define a positioning space consistent with the size of the tray, the tray is fixed in the positioning space, so as not to be separated from the third support plate 314 during reciprocating movement. The third driving piece 315 is arranged on the inner side of one of the first fixed plates 311, which is more beautiful and does not occupy external space, the driving end of the third driving piece 315 is connected with the third support plate 314 to drive the third support plate 314 to slide along the third sliding rail 312 to realize the switching at the first end and the second end. Similarly, as shown in Figures 7 to 9As shown, the second interface assembly 32 comprises a second fixed plate 321, a fourth sliding block 323, a fourth support plate 326, a third sliding seat 324, and a fourth driving member 329. Since the first interface assembly 31 and the second interface assembly 32 move towards each other, in order to avoid collision and interference between the first interface assembly 31 and the second interface assembly 32 during the movement towards each other, the second interface assembly 32 further comprises a guide plate 327, a guide connecting member 328, and a lifting guide rod 325 in the embodiment. Specifically, the number of the second fixed plate 321 is also two, and the two second fixed plates 321 are oppositely and spacedly arranged in the space between the two first fixed plates 311 along the second straight line 300 direction. The height of the second fixed plate 321 is lower than the height of the first fixed plate 311. Similarly, the second fixed plate 321 extends along the first straight line 200 direction. The top end of any second fixed plate 321 is fixed with a fourth sliding rail 322. Similarly, the extension direction of the fourth sliding rail 322 is consistent with the extension direction of the second fixed plate 321, that is, along the first straight line 200 direction. At least one fourth sliding block 323 (exemplarily two) is slidably arranged on the fourth sliding rail 322. A horizontal plate-shaped third sliding seat 324 is fixed on the fourth sliding block 323. The third sliding seat 324 is provided to facilitate the installation of the lifting guide rod 325 and the guide connecting member 328. The lifting guide rod 325 is slidably arranged on the third sliding seat 324 in a vertical lifting manner. In the embodiment, the number of the lifting guide rod 325 is four, and the four lifting guide rods 325 are respectively distributed at the four corner positions of the third sliding seat 324. Preferably, four guide sliding sleeves 3210 are provided on the third sliding seat 324. Each lifting guide rod 325 is in sliding fit with a guide sliding sleeve 3210. The fourth support plate 326 is a horizontal plate and is fixed at the top end of the lifting guide rod 325. Similarly, in order to prevent the tray from falling off the fourth support plate 326 during the interface switching movement, four L-shaped limiting blocks (not marked) are provided on the fourth support plate 326. The four limiting blocks define a positioning space matching the size of the tray. The guide plate 327 is fixed on the machine body 100 and located in the space between the two second fixed plates 321 and at the bottom of the third sliding seat 324. In order to facilitate the sliding connection between the guide connecting member 328 and the guide plate 327, an avoiding through hole 3241 is formed in the third sliding seat 324. Meanwhile, a guide groove 3271 is formed in one side of the guide plate 327. The guide connecting member 328 is in sliding connection in the guide groove 3271 of the side of the guide plate 327 after penetrating through the avoiding through hole 3241 of the third sliding seat 324 in a vertical manner. It should be noted that the guide plate 327 extends along the first straight line 200 direction. Similarly, the guide groove 3271 also extends along the first straight line 200 direction. In order to realize the lifting of the fourth support plate 326, the guide groove 3271 in the embodiment is not a straight groove, but a strip-shaped groove with higher height at both ends, that is, near the first end and near the second end, and lower height at the middle position. In an exemplary embodiment, Figure 9As shown, the guide groove 3271 includes, in order from the first end to the second end, a first horizontal groove segment, a first inclined groove segment, a second horizontal groove segment, a second inclined groove segment, and a third horizontal groove segment, wherein the first inclined groove segment and the second inclined groove segment are symmetrical, the first horizontal groove segment and the third horizontal groove segment are symmetrical, the length of the second horizontal groove segment is greater than that of the first horizontal groove segment and the third horizontal groove segment, when the guide connecting piece 328 is located in the second horizontal groove segment of the guide groove 3271, the fourth support plate 326 is at the lowest position, at which it just meets the third support plate 314, so that it can pass through the bottom of the third support plate 314, after passing through, the guide connecting piece 328 is just located in the first inclined groove segment or the second inclined groove segment, and when the guide connecting piece 328 is located in the first horizontal groove segment or the third horizontal groove segment, the fourth support plate 326 is at the highest position and is at the same height position as the third support plate 314. The driving end of the fourth driving piece 329 is connected with the third sliding seat 324 to drive the third sliding seat 324 and the fourth support plate 326 to move along the first straight line 200. It should be noted that the third driving piece 315 and the fourth driving piece 329 need to be synchronized to avoid collision interference when the first transfer assembly 31 and the second transfer assembly 32 meet and transfer. The third driving piece 315 and the fourth driving piece 329 can be selected as a conventional servo motor and a driving belt 333. In the preferred embodiment, the third driving piece 315 and the fourth driving piece 329 share the same driving piece (for the sake of description, it is defined as a shared driving piece), which can reduce the number of components and the occupied space.
