Detailed Implementation

[0056] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0057] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0058] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0059] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0061] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 4 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The marked directions. The axes in the X, Y, and Z directions intersect each other. The axial direction of connecting rod 132 is the same as the Y direction.

[0062] like Figures 1-9 As shown, according to a first aspect of the embodiments of this application, a conveying mechanism 100 is provided, including at least one first conveying section 1. The first conveying section 1 includes a first conveying assembly 11, a second conveying assembly 12, and a first driving assembly 13. The second conveying assembly 12 is spaced apart from the first conveying assembly 11. The first driving assembly 13 includes a first driving member 131, a connecting rod 132, a first eccentric wheel 133, a second eccentric wheel 134, a first driven part 135, and a second driven part (not shown in the figure, please refer to the structure of the first driven part 135). The connecting rod 132 is connected to the driving end of the first driving member 131. The first eccentric wheel 133 and the second eccentric wheel 134 are spaced apart on the connecting rod 132. The first eccentric wheel 133 is axially movable relative to the connecting rod 132. The first driven part 135 is disposed on the first conveying assembly 11 and abuts against the first eccentric wheel 133. The second driven part is disposed on the second conveying assembly 12 and abuts against the second eccentric wheel 134.

[0063] like Figure 1 As shown, the conveying mechanism 100 includes at least one first conveying section 1, which can be understood as the conveying mechanism 100 including one first conveying section 1, two first conveying sections 1, three first conveying sections 1 or more first conveying sections 1.

[0064] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first conveying section 1 includes a first conveying component 11 and a second conveying component 12; the first conveying component 11 and the second conveying component 12 are spaced apart along the Y direction, and a tray or workpiece is placed between the first conveying component 11 and the second conveying component 12. The first conveying component 11 and the second conveying component 12 work together to convey the tray or workpiece along the X direction; a carrying mechanism 300 is provided between the first conveying component 11 and the second conveying component 12, and the carrying mechanism 300 is used to carry the tray or workpiece. The dispensing mechanism 400 dispenses glue onto the workpiece or workpiece on the tray; in this embodiment, the dispensing of glue onto the workpiece on the tray is taken as an example.

[0065] Further explanation: the first conveying section 1 also includes a first drive assembly 13, which includes a first drive member 131, a connecting rod 132, a first eccentric wheel 133, a second eccentric wheel 134, a first driven part 135, and a second driven part. The connecting rod 132 is connected to the drive end of the first drive member 131, and the first drive member 131 can drive the connecting rod 132 to rotate around its own axis. The first eccentric wheel 133 and the second eccentric wheel 134 are spaced apart on the connecting rod 132 along the Y direction. That is, when the first drive member 131 drives the connecting rod 132 to rotate around its own axis, it can drive the first eccentric wheel. The first conveying assembly 11 and the second eccentric wheel 133 rotate; the first conveying assembly 11 and the first eccentric wheel 133 are spaced apart in the Z direction, and the first driven part 135 abuts against the first eccentric wheel 133 (abutting means that a portion of the first driven part 135 will contact a portion of the first eccentric wheel 133; when the first eccentric wheel 133 rotates, it can drive the first driven part 135 to move in the Z direction). The first driven part 135 is provided on the first conveying assembly 11. The second conveying assembly 12 and the second eccentric wheel 134 are spaced apart in the Z direction, and the second driven part abuts against the second eccentric wheel 134 (abutting means that a portion of the second driven part will contact the second eccentric wheel 134). Partial contact of eccentric wheel 134; when the second eccentric wheel 134 rotates, it can drive the second driven part to move in the Z direction. The second driven part is provided in the second conveying assembly 12. Specifically, when the first driving member 131 drives the connecting rod 132 to rotate around its own axis, the first eccentric wheel 133 and the second eccentric wheel 134 will also rotate simultaneously. The first driven part 135 abuts against the first eccentric wheel 133, and the second driven part abuts against the second eccentric wheel 134. The first eccentric wheel 133 can drive the first driven part 135 to move in the Z direction, and the second eccentric wheel 134 can drive the second driven part to move in the Z direction. The first conveying assembly 11 and the second conveying assembly 12 can be driven to move downward in the Z direction to place the tray on the support mechanism 300, or driven to move upward in the Z direction to lift the tray off the support mechanism 300 to detach it from the support mechanism 300; and the first eccentric wheel 133 can move axially relative to the connecting rod 132, and the first eccentric wheel 133 can also move in the Y direction toward or away from the second eccentric wheel 134, thereby adjusting the distance between the first conveying assembly 11 and the second conveying assembly 12 in the Y direction to accommodate trays of different sizes.

[0066] The first eccentric wheel 133 can be driven to move axially relative to the connecting rod 132 in the Y direction by the first driving member 131, or the first eccentric wheel 133 can be manually driven to move axially relative to the connecting rod 132 in the Y direction.

[0067] The conveying mechanism 100 provided in this application can adjust the distance between the first conveying component 11 and the second conveying component 12 by controlling the position of the first eccentric wheel 133 on the connecting rod 132 to accommodate material trays of different sizes. It can also adjust the position of the first conveying component 11 and the second conveying component 12 in the Z direction using the first driving component 131. Compared with the prior art which sets multiple driving components, this application only needs the first driving component 13 to solve the problem of the distance between the first conveying component and the second conveying component in the Y direction and the lifting and lowering in the Z direction. Therefore, this application can solve the problems of large space occupation and high cost of the conveying mechanism 100 in the prior art.

[0068] In one alternative implementation, such as Figure 5 and Figure 6 As shown, the first driven part 135 includes a first roller 1351 and a first connecting member 1352. The first eccentric wheel 133 includes a first abutting surface 1331. The first roller 1351 abuts against the first abutting surface 1331. The first roller 1351 is disposed on the first connecting member 1352. The first connecting member 1352 is connected to the first conveying assembly 11. Specifically, the first roller 1351 and the first connecting member 1352 are rotatably connected. The rotation axis of the first roller 1351 and the first connecting member 1352 are parallel to the axis in the Y direction. The first roller 1351 abuts against the first abutting surface 1331 of the first eccentric wheel 133. The first connecting member 1352 is connected to the first conveying assembly 11. Therefore, when the first eccentric wheel 133 rotates, the first roller 1351 will be located at different positions on the first abutting surface 1331 of the first eccentric wheel 133, thereby driving the first conveying assembly 11 to move in the Z direction.

[0069] The second driven part includes a second roller and a second connecting member. The second eccentric wheel 134 includes a second abutting surface. The first roller 1351 abuts against the second abutting surface. The second roller is disposed on the second connecting member, and the second connecting member is connected to the second conveying assembly 12. Specifically, the second roller is rotatably connected to the second connecting member. The rotation axis of the second roller and the second connecting member is parallel to the axis in the Y direction. The second roller abuts against the second abutting surface of the second eccentric wheel 134. The second connecting member is connected to the second conveying assembly 12. Therefore, when the second eccentric wheel 134 rotates, the second roller will be located at different positions on the second abutting surface of the second eccentric wheel 134, thereby driving the second conveying assembly 12 to move in the Z direction.

[0070] In one alternative embodiment, the distance from different positions of the first abutment surface 1331 to the center of the connecting rod 132 is different; that is, the distance between the first abutment surface 1331 and the first roller 1351, and the distance between the center of the connecting rod 132 and different positions of the first abutment surface 1331, is also different.

[0071] In one specific implementation, refer to the appendix. Figure 10 As shown in the figure, the dashed lines represent different positions from the center of the connecting rod 132 to the first abutment surface 1331. The lengths of the multiple dashed lines shown in the figure are different, which means the distance between the center of the connecting rod 132 and the first abutment surface 1331 is different at different positions; when the first eccentric wheel 133 moves from... Figure 10 Rotate position a to Figure 10 At position b, its first roller 1351 moves upward in the Z direction, which means that the first conveying assembly 11 is driven to move upward in the Z direction; when the first eccentric wheel 133 moves from... Figure 10 Position b rotated to Figure 10 At position a, the first roller 1351 moves downward in the Z direction, which means that the first conveying assembly 11 is driven to move downward in the Z direction.

[0072] In another specific implementation, refer to the appendix. Figure 11 As shown in the figure, the dashed lines represent different positions from the center of the connecting rod 132 to the first abutment surface 1331. The lengths of the multiple dashed lines shown in the figure are different, which means the distance between the center of the connecting rod 132 and the first abutment surface 1331 is different at different positions; when the first eccentric wheel 133 moves from... Figure 11 Rotate position a to Figure 11 At position b, its first roller 1351 moves upward in the Z direction, which means that the first conveying assembly 11 is driven to move upward in the Z direction; when the first eccentric wheel 133 moves from... Figure 11 Position b rotated to Figure 11 At position a, the first roller 1351 moves downward in the Z direction, which means that the first conveying assembly 11 is driven to move downward in the Z direction.

[0073] In another specific implementation, refer to the appendix. Figure 12 As shown in the figure, the dashed lines represent different positions from the center of the connecting rod 132 to the first abutment surface 1331. The lengths of the multiple dashed lines shown in the figure are different, which means the distance between the center of the connecting rod 132 and the first abutment surface 1331 is different at different positions; when the first eccentric wheel 133 moves from... Figure 12 Rotate position a to Figure 12At position b, its first roller 1351 moves upward in the Z direction, which means that the first conveying assembly 11 is driven to move upward in the Z direction; when the first eccentric wheel 133 moves from... Figure 12 Position b rotated to Figure 12 At position a, the first roller 1351 moves downward in the Z direction, which means that the first conveying assembly 11 is driven to move downward in the Z direction.

[0074] The distance from different positions of the second abutment surface to the center of the connecting rod 132 is different. The shape of the second abutment surface can be referenced... Figure 10 , Figure 11 and Figure 12 The first contact surface 1331 and the second contact surface have the same shape to ensure that the first conveying component 11 and the second conveying component 12 can move upward or downward in the Z direction at the same time.

[0075] In one specific embodiment, the first eccentric wheel 133 includes a first cam 1333, the first eccentric wheel 133 is provided with a first groove 1332, the first cam 1333 is disposed in the first groove 1332, the first abutting surface 1331 is located in the first cam 1333, and the first roller 1351 is located in the first groove 1332 and abuts against the first abutting surface 1331.

[0076] In another specific embodiment, the second eccentric wheel 134 includes a second cam (not shown in the figure, please refer to the structure of the first eccentric wheel 133), the second eccentric wheel 134 is provided with a second groove, the second cam is provided in the second groove, the second abutting surface is located on the second cam, and the second roller is located in the second groove and abuts against the second abutting surface.

[0077] like Figure 5 and Figure 6As shown, in another specific embodiment, taking this embodiment as an example for explanation, the first eccentric wheel 133 includes a first cam 1333, the first eccentric wheel 133 has a first groove 1332, the first cam 1333 is disposed in the first groove 1332, the first abutting surface 1331 is located on the first cam 1333, and the first roller 1351 is located in the first groove 1332 and abuts against the first abutting surface 1331; specifically, the first groove 1332 is formed on the end face of the first eccentric wheel 133, and the first cam 1333 is disposed in the first groove 1332. Within the first groove 1332, a first receiving space is formed between the first cam 1333 and the inner wall of the first groove 1332. The first roller 1351 is located within this first receiving space and abuts against the first contact surface 1331 on the first cam 1333. In this embodiment, the first roller 1351 abuts against the first contact surface 1331 within the first groove 1332. When the first eccentric wheel 133 rotates, the first roller 1351 rotates relative to the first contact surface 1331 within the first groove 1332. The first groove 1332 provides mounting support for the first roller 1351. The second eccentric wheel 134 includes a second cam and a second groove. The second cam is located within the second groove, and the second contact surface is located on the second cam. The second roller is located within the second groove and abuts against the second contact surface. Specifically, a second groove is provided on the end face of the second eccentric wheel 134, and a second cam is disposed in the second groove. The second cam and the inner wall of the second groove form a second receiving space. The second roller is located in the second receiving space of the second groove, and the second roller abuts against the second abutting surface on the second cam. In this embodiment, the second roller abuts against the second abutting surface in the first groove 1332. When the second eccentric wheel 134 rotates, the second roller rotates relative to the second abutting surface in the second groove. The second groove can provide mounting support for the second roller.

[0078] like Figure 5As shown, in an embodiment where the first eccentric wheel 133 is moved along the Y direction relative to the axis of the connecting rod 132 by manual driving, the connecting rod 132 has a groove 1321, and the first eccentric wheel 133 has a first slider 140. The first slider 140 and the groove 1321 are slidably connected along the axial direction of the connecting rod 132. The first eccentric wheel 133 has a through hole, and the first slider 140 is disposed on the inner wall of the through hole. The connecting rod 132 passes through the through hole, and the first slider 140 and the groove 140 are slidably connected along the axial direction of the connecting rod 132. The groove 1321 is fitted, and the length direction of the groove 1321 is the same as the axis of the connecting rod 132. Therefore, the first eccentric wheel 133 can move in the Y direction along the groove 1321 via the first slider 140. In this embodiment, by manually driving the first conveying assembly 11 to move in the Y direction, the first eccentric wheel 133 can move in the Y direction along the groove 1321 via the first slider 140, thereby adjusting the distance between the first conveying assembly 11 and the second conveying assembly 12 in the Y direction to accommodate different sized trays.

[0079] In the embodiment where the first eccentric wheel 133 is driven to move axially relative to the connecting rod 132 in the Y direction by the first driving member 131, the connecting rod 132 is a lead screw, and the first eccentric wheel 133 is rotatably connected to the connecting rod 132. When the first driving member 131 drives the connecting rod 132 to rotate around its own axis, the first eccentric wheel 133 also moves relative to the connecting rod 132 in the Y direction while rotating around its own axis. In this embodiment, when adjusting the movement of the first conveying assembly 11 and the second conveying assembly 12 in the Z direction, their movement size in the Z direction is small, and the rotation angle of the first eccentric wheel 133 will not exceed 360°. Therefore, the movement distance of the first conveying assembly 11 in the Y direction is also relatively small. When the first conveying component 11 and the second conveying component 12 are working normally, the movement distance of the first conveying component 11 in the Y direction will not affect its operation. When it is necessary to adjust the distance between the first conveying component 11 and the second conveying component 12 in the Y direction, the first conveying component 11 and the second conveying component 12 are not yet in working state, so their spacing can be adjusted normally to adapt to the size of the tray. After the adjustment is completed, the first conveying component 11 and the second conveying component 12 will start working. In this embodiment, the first driving member 131 can simultaneously drive the first conveying component 11 and the second conveying component 12 to move in the Z direction and the spacing between the first conveying component 11 and the second conveying component 12 in the Y direction, thereby reducing the space occupied by the conveying mechanism 100.

[0080] like Figure 5 and Figure 6As shown, in one optional embodiment, the first drive assembly 13 further includes a first mounting base 137 and a second mounting base 138, the first mounting base 137 and the second mounting base 138 being spaced apart along the Y direction, the first conveying assembly 11 and the second conveying assembly 12 being located between the first mounting base 137 and the second mounting base 138 in the Y direction, the connecting rod 132 being rotatably connected to the first mounting base 137 and the second mounting base 138 respectively, and the first mounting base 137 and the second mounting base 138 providing support for the connecting rod 132.

[0081] like Figure 5 As shown, in an optional embodiment, the first drive assembly 13 further includes an angle sensor 139, which is disposed on the connecting rod 132 and is used to detect the rotation angle of the connecting rod 132.

[0082] In another alternative implementation, such as Figure 3 and Figure 6 As shown, taking this embodiment as an example, the first conveying assembly 11 includes a second driving member 111, a first driving wheel 112, a first driven wheel 113, a first conveyor belt 114, and a first mounting bracket 115. The first driving wheel 112 and the first driven wheel 113 are spaced apart, and both the first driving wheel 112 and the first driven wheel 113 are rotatably connected to the first mounting bracket 115. The first driving wheel 112 is connected to the output end of the second driving member 111, and the first conveyor belt 114 is sleeved on the first driving wheel 112 and the first driven wheel 113. The second conveying assembly 12 includes a third driving member 121, a second driving wheel 122, a second driven wheel 123, a second conveyor belt 124, and a second mounting bracket 125. The second driving wheel 122 and the second driven wheel 123 are spaced apart. The second driving wheel 122 and the second driven wheel 123 are both rotatably connected to the second mounting bracket 125. The second driving wheel 122 is connected to the output end of the second driving member 111. The second conveyor belt 124 is sleeved on the second driving wheel 122 and the second driven wheel 123. Specifically, the first driving wheel 112 and the first driven wheel 113 are spaced apart along the X direction, and the second driving wheel 122 and the second driven wheel 123 are spaced apart along the X direction. The first driving wheel 112 is driven to rotate around its own axis by the second driving member 111, thereby driving the first conveyor belt 114 to move in the X direction. The second driving wheel 122 is driven to rotate around its own axis by the third driving member 121, thereby driving the second conveyor belt 124 to move in the X direction. The material tray is supported and conveyed in the X direction by the first conveyor belt 114 and the second conveyor belt 124.

[0083] In an optional embodiment, the first driving wheel 112, the first driven wheel 113, the second driving wheel 122, and the second driven wheel 123 each include a first body 1121, a first baffle 1122, and a second baffle 1123. The first baffle 1122 and the second baffle 1123 are disposed on both sides of the axial direction of the first body 1121. Along the axial direction of the first body 1121, the diameter of the radial cross-section at both ends of the first body 1121 is smaller than the diameter of the radial cross-section at the middle of the first body 1121.

[0084] like Figure 7 , Figure 8 and Figure 9 As shown, specifically, taking the structure of the first driving wheel 112 as an example, the first driving wheel 112 includes a first body 1121, a first baffle 1122, and a second baffle 1123. The first baffle 1122 and the second baffle 1123 are disposed on both sides of the axial direction of the first body 1121. Along the axial direction of the first body 1121, the diameter of the radial cross-section at both ends of the first body 1121 is smaller than the diameter of the radial cross-section at the middle of the first body 1121. Specifically, along the axial direction of the first body 1121, the diameter of the radial cross-section at both ends of the first body 1121 is smaller than the diameter of the radial cross-section at the middle of the first body 1121. This can be understood as the first body... The outer surface of 1121 is higher in the middle and lower on both sides, which can also be understood as the first body 1121 being a drum-shaped wheel; in the axial direction of the first body 1121, the first baffle 1122 and the second baffle 1123 are respectively located on both sides of the first body 1121, and the first baffle 1122 and the second baffle 1123 protrude from the outer surface of the first body 1121; the first conveyor belt 114 is sleeved on the outer surface of the first body 1121, and the first baffle 1122 and the second baffle 1123 can prevent the first conveyor belt 114 from detaching from the first body 1121. The outer surface of the first body 1121 is higher in the middle and lower on both sides, which can prevent the first conveyor belt 114 from rubbing against the first baffle 1122 and the second baffle 1123.

[0085] The first driven wheel 113, the second driving wheel 122, and the second driven wheel 123 have the same structure as the first driving wheel 112, and their technical effects are also the same, so they will not be described in detail here.

[0086] like Figure 1 , Figure 2 and Figure 4As shown, in an optional embodiment, the conveying mechanism 100 further includes at least one second conveying section 2, which is arranged adjacent to the first conveying section 1. The second conveying section 2 includes a third conveying component 21 and a fourth conveying component 22, which are spaced apart. The second conveying section 2 and the first conveying section 1 are arranged adjacent to each other along the X direction, the third conveying component 21 and the fourth conveying component 22 are spaced apart along the Y direction, the third conveying component 21 and the first conveying component 11 are arranged adjacent to each other along the X direction, and the fourth conveying component 22 and the second conveying component 12 are arranged adjacent to each other along the X direction. The carrying mechanism 300 is disposed on the first conveying component 11. Between the first conveying component 11 and the second conveying component 12; in this embodiment, the tray is conveyed along the X direction to the space between the first conveying component 11 and the second conveying component 12 via the third conveying component 21 and the fourth conveying component 22. The first driving component 13 drives the first conveying component 11 and the second conveying component 12 to move downward along the Z direction to place the tray on the carrying mechanism 300. The dispensing mechanism 400 dispenses glue onto the workpiece on the tray. After the dispensing is completed, the first driving component 13 drives the first conveying component 11 and the second conveying component 12 to move upward along the Z direction. The tray is then separated from the carrying mechanism 300. The first conveying component 11 and the second conveying component 12 drive the tray to move along the X direction to unload it.

[0087] In one optional embodiment, the third conveying assembly 21 includes a fourth driving member, a third driving wheel, a third driven wheel, a third conveyor belt, and a third mounting bracket. The third driving wheel and the third driven wheel are spaced apart, and both the third driving wheel and the third driven wheel are rotatably connected to the third mounting bracket. The third driving wheel is connected to the output end of the fourth driving member, and the third conveyor belt is sleeved on the third driving wheel and the third driven wheel. The fourth conveying assembly 22 includes a fifth driving member, a fourth driving wheel, a fourth driven wheel, a fourth conveyor belt, and a fourth mounting bracket. The fourth driving wheel and the fourth driven wheel are spaced apart, and the fourth driving wheel and the third driven wheel are rotatably connected to the third mounting bracket. The third driving wheel and the third driven wheel are connected to the output end of the fourth driving member, and the third conveyor belt is sleeved on the third driving wheel and the third driven wheel. The fourth driven wheels are all rotatably connected to the fourth mounting bracket, the fourth driving wheel is connected to the output end of the fifth driving member, and the fourth conveyor belt is sleeved on the fourth driving wheel and the fourth driven wheel; specifically, the third driving wheel and the third driven wheel are spaced apart along the X direction, and the fourth driving wheel and the fourth driven wheel are spaced apart along the X direction; the third driving wheel is driven to rotate around its own axis by the fourth driving member, thereby driving the third conveyor belt to move in the X direction, and the fourth driving wheel is driven to rotate around its own axis by the fourth driving member, thereby driving the fourth conveyor belt to move in the X direction, and the material tray is supported and conveyed in the X direction by the third conveyor belt and the fourth conveyor belt.

[0088] The structures of the third and fourth conveying components are described with reference to the structures of the first conveying component 11 and the second conveying component 12.

[0089] In one optional embodiment, the third driving wheel, the third driven wheel, the fourth driving wheel, and the fourth driven wheel each include a second body, a third baffle, and a fourth baffle. The third baffle and the fourth baffle are disposed on both sides of the axial direction of the second body. Along the axial direction of the second body, the diameter of the radial cross-section at both ends of the second body is smaller than the diameter of the radial cross-section in the middle of the second body.

[0090] Specifically, taking the structure of the third drive wheel as an example, the third drive wheel includes a second body, a third baffle, and a fourth baffle. The third and fourth baffles are located on both sides of the axial direction of the second body. Along the axial direction of the second body, the diameter of the radial section at both ends of the second body is smaller than the diameter of the radial section in the middle of the second body. Specifically, along the axial direction of the second body, the diameter of the radial section at both ends of the second body is smaller than the diameter of the radial section in the middle of the second body. This can be understood as the outer surface of the second body being higher in the middle and lower on both sides, or as the second body being a drum-shaped wheel. Along the axial direction of the second body, the third and fourth baffles are located on both sides of the second body, and the third and fourth baffles protrude from the outer surface of the second body. The third conveyor belt is sleeved on the outer surface of the second body. The third and fourth baffles can prevent the third conveyor belt from detaching from the second body. The fact that the outer surface of the second body is higher in the middle and lower on both sides can prevent the third conveyor belt from rubbing against the third and fourth baffles.

[0091] The third driving wheel, the third driven wheel, the fourth driving wheel, and the fourth driven wheel have the same structure and the same technical effect, so they will not be described in detail here.

[0092] like Figure 1 , Figure 2 and Figure 4As shown, in an optional embodiment, the conveying mechanism 100 includes two first conveying sections 1 and two second conveying sections 2. The two first conveying sections 1 are arranged adjacent to each other along the conveying direction of the first conveying sections 1, and the two second conveying sections 2 are located on both sides of the two first conveying sections 1 respectively along the conveying direction of the first conveying sections 1. Specifically, the conveying direction of the first conveying section 1 is the same as the X direction; therefore, along the X direction, there is one second conveying section 2, one first conveying section 1, another first conveying section 1, and another second conveying section 2 in sequence. The first conveying section 1 can move the material tray in the Z direction, so a bearing mechanism 300 (i.e., a dispensing station) is provided in each first conveying section 1 to achieve dual-station dispensing. The two second conveying sections 2 can only convey the material tray in the X direction, so the two second conveying sections 2 are respectively a loading station and a unloading station.

[0093] In one specific embodiment, the first conveying section 1 further includes a first blocking component 3, which is disposed between the first conveying component 11 and the second conveying component 12 in the axial direction of the connecting rod 132.

[0094] In another specific embodiment, the second conveying section 2 further includes a second blocking component 4, which is disposed between the third conveying component 21 and the fourth conveying component 22 in the axial direction of the connecting rod 132.

[0095] like Figure 1 As shown, in another specific embodiment, taking this embodiment as an example for explanation, the first conveying section 1 further includes a first blocking component 3, which is disposed between the first conveying component 11 and the second conveying component 12 along the axial direction of the connecting rod 132. In this embodiment, when the tray is in the first conveying section 1, the tray is placed on the carrying mechanism 300 for dispensing. The first blocking component 3 restricts the movement of the tray located on the first conveying component 11 and the second conveying component 12 in the X direction. After the dispensing of the workpiece on the tray is completed, the first blocking component 3 releases the restriction, and the first conveying component 11 and the second conveying component 12 move in the X direction. The conveyor tray 12 moves along the X direction; the second conveyor section 2 also includes a second blocking component 4, which is disposed between the third conveyor component 21 and the fourth conveyor component 22 in the axial direction of the connecting rod 132; specifically, in this embodiment, when the tray is in the second conveyor section 2, and the tray needs to stay in the second conveyor section 2, the second blocking component 4 restricts the tray located on the third conveyor component 21 and the fourth conveyor component 22 from moving along the X direction. When the tray needs to move along the X direction, the second blocking component 4 releases the restriction, and the third conveyor component 21 and the fourth conveyor component 22 convey the tray to move along the X direction.

[0096] The first blocking component 3 includes a sixth driving member 31 and a first blocking member 32. The first blocking member 32 is located at the driving end of the sixth driving member 31, and the sixth driving member 31 can drive the first blocking member 32 to move along the Z direction.

[0097] The second blocking component 4 includes a seventh driving member 41 and a second blocking member 42. The second blocking member 42 is disposed at the driving end of the seventh driving member 41, and the seventh driving member 41 can drive the second blocking member 42 to move along the Z direction.

[0098] like Figure 1 , Figure 2 and Figure 4 As shown, in an optional embodiment, the conveying mechanism 100 further includes a mounting assembly 5, which includes a first mounting plate 51, a second mounting plate 52, and a mounting base 53. The first mounting plate 51 and the second mounting plate 52 are spaced apart along the axial direction of the connecting rod 132. The first conveying assembly 11 is slidably disposed on the first mounting plate 51, the second conveying assembly 12 is slidably disposed on the second mounting plate 52, the third conveying assembly 21 is disposed on the first mounting plate 51, and the fourth conveying assembly 22 is disposed on the second mounting plate 52. The first mounting plate 51 and the mounting base 53 are slidably connected along the axial direction of the connecting rod 132. Specifically, the first conveying assembly 11 is slidably connected to the first mounting plate 51 along the Z direction, the second conveying assembly 12 is slidably connected to the second mounting plate 52 along the Z direction, and the third conveying assembly 21 is slidably connected to the first mounting plate 51. The fourth conveying component 22 is fixedly connected to the second mounting plate 52. When the first driving component 13 drives the first conveying component 11 and the second conveying component 12 to move along the Z direction, the first conveying component 11 will move relative to the first mounting plate 51 along the Z direction, and the second conveying component 12 will move relative to the second mounting plate 52 along the Z direction, while the third conveying component 21 and the fourth conveying component 22 will not move in the Z direction. When the first driving component 13 drives the first conveying component 11 to move along the Y direction, the first mounting plate 51 can simultaneously drive the third conveying component 21 to move along the Y direction, thereby enabling adjustment of the distance between the first conveying component 11 and the second conveying component 12, as well as the distance between the third conveying component 21 and the fourth conveying component 22. The first mounting plate 51 and the mounting base 53 are slidably connected along the Y direction to improve the stability of the first mounting plate 51 moving along the Y direction.

[0099] In an embodiment where the first eccentric wheel 133 is moved along the Y direction relative to the axis of the connecting rod 132 by manual driving, the conveying mechanism 100 further includes a braking assembly 6, which is used to restrict the sliding of the first mounting plate 51 relative to the mounting base 53. After the conveying mechanism 100 adjusts the distance between the first conveying assembly 11 and the second conveying assembly 12, the braking assembly 6 restricts the sliding of the first mounting plate 51 relative to the mounting base 53, thereby restricting the movement of the first conveying assembly 11 relative to the second conveying assembly 12 to ensure the normal operation of the conveying mechanism 100.

[0100] In an optional embodiment, the mounting assembly 5 further includes a first slide rail, a second slide rail, a second slider, and a third slider; the first mounting plate 51 and the first conveying assembly 11 are slidably connected to the first slide rail via the second slider; specifically, if the second slider is disposed on the first mounting plate 51, then the first slide rail is disposed on the first conveying assembly 11; or, if the second slider is disposed on the first conveying assembly 51, then the first slide rail is disposed on the first mounting plate 51, and the second slider and the first slide rail are slidably connected in the Z direction. Therefore, the first conveying assembly 11 can move relative to the first mounting plate 51 in the Z direction, and the second slider and the first slide rail can provide guidance and support for the first conveying assembly 11 to move in the Z direction.

[0101] The second mounting plate 52 and the second conveying assembly 12 are slidably connected to the third slider via the second slide rail. Specifically, if the third slider is disposed on the second mounting plate 52, then the second slide rail is disposed on the second conveying assembly 12; or, if the third slider is disposed on the second conveying assembly 521, then the second slide rail is disposed on the second mounting plate 52. The third slider and the second slide rail are slidably connected along the Z-direction. Therefore, the second conveying assembly 12 can move relative to the second mounting plate 52 along the Z-direction, and the third slider and the second slide rail can provide guidance and support for the movement of the second conveying assembly 12 along the Z-direction. Figure 2 As shown, according to a first aspect of the embodiments of this application, a dispensing apparatus 1000 is provided, including the aforementioned conveying mechanism 100.

[0102] like Figure 13 As shown, in an optional embodiment, the dispensing device 1000 further includes a driving mechanism 200, a carrying mechanism 300, and at least one dispensing mechanism 400. The dispensing mechanism 400 is disposed at the driving end of the driving mechanism 200 and is located above the conveying mechanism 100 in the Z direction. The carrying mechanism 300 is disposed at the conveying mechanism 100. Specifically, the carrying mechanism 300 is disposed between the first conveying assembly 11 and the second conveying assembly 12.

[0103] The dispensing mechanism 400 includes a second driving component 401, a third driving component 404, a first rotating component 402, and a dispensing component 403. The second driving component 401 is disposed at the driving end of the driving mechanism 400, and the driving mechanism 200 can drive the second driving component 401 to move along the X direction. The third driving component 404 is disposed at the driving end of the second driving component 401, and the second driving component 401 can drive the third driving component 404 to move along the Y direction. The first rotating component 402 is disposed at the driving end of the third driving component 404, and the third driving component 404 can drive the first rotating component 402 to move along the Y direction. Moving along the Z direction, the first rotating component 402 can drive the dispensing component 403 to rotate around the Z-axis; the Y direction is the same as the axial direction of the connecting rod 132, and the X direction is the same as the conveying direction of the conveying mechanism 100; specifically, the dispensing component 403 can be driven to move in the X, Y, and Z directions by the driving mechanism 200, the second driving component 401, and the third driving component 404, and the second rotating component 402 can adjust the angle of the dispensing component 403 to adjust the position of the dispensing component 403 and the tray located on the conveying mechanism 100, so that the dispensing component 403 can dispense glue to the workpiece located on the tray.

[0104] like Figure 13 As shown, in an optional embodiment, the dispensing mechanism 400 further includes a second rotating component 405, which is connected to the rotating end of the second rotating component 402. The first rotating component 402 can drive the second rotating component 405 to rotate about an axis in the Z direction. The dispensing component 403 is disposed at the rotating end of the second rotating component 405, and the second rotating component 405 can drive the dispensing component 403 to rotate about an axis perpendicular to the Z direction. Specifically, the angle of the dispensing component 403 can be further adjusted by the second rotating component 405 to facilitate the dispensing component 403 to dispense glue to the workpiece, thereby improving the dispensing quality.

[0105] The dispensing assembly 403 is driven to move by a drive mechanism 200, a second drive component 401, a third drive component 404, a first rotating component 402, and a second rotating component 405. The dispensing mechanism 400 is located above the conveying mechanism 100 in the Z direction and is also spaced apart from the conveying mechanism 100 in the X direction.

[0106] In one specific embodiment, the dispensing device 1000 further includes a first detection mechanism, which is disposed on the second drive assembly 401.

[0107] In another specific embodiment, the dispensing device 1000 further includes a second detection mechanism, which is disposed above the support mechanism 300 in the Z direction.

[0108] In another specific embodiment, the dispensing device 1000 further includes a third detection mechanism 600, which is disposed on the second drive assembly 401.

[0109] In another specific embodiment, the dispensing device 1000 further includes a first detection mechanism (not shown in the figure), a second detection mechanism (not shown in the figure), and a third detection mechanism 600; the first detection mechanism is disposed on the second driving assembly 401; the second detection mechanism is disposed above the dispensing assembly 403 in the Z direction; the third detection mechanism 600 is disposed on the second driving assembly 401; taking this embodiment as an example, the first detection mechanism can be a dot laser assembly to detect the positional relationship between a workpiece located on the tray and the dispensing assembly 403, and the second detection mechanism is a 3D camera, which is used to detect the entire process in one operation. The positional relationship between all workpieces on the tray and the dispensing assembly 403 is determined by the first and second detection mechanisms, which facilitate the movement of the dispensing assembly 403 by the drive mechanism 200, the second drive assembly 401, the third drive assembly 404, the first rotation assembly 402, and the second rotation assembly 405 to adjust the position of the dispensing assembly 403. The first detection mechanism performs fine-tuning of the dispensing assembly 403, and the second detection mechanism performs coarse-tuning. The third detection mechanism 600 is a 3D camera, which is used to detect whether the dispensed workpiece is qualified and can also be used to capture the QR code located on the workpiece or the tray.

[0110] In one optional embodiment, the dispensing device 1000 includes two dispensing mechanisms 400 and two carrying mechanisms 300, the two dispensing mechanisms 400 being spaced apart along the X direction, and the two carrying mechanisms 300 being spaced apart along the X direction.

[0111] like Figure 13As shown, the dispensing device 1000 includes two dispensing mechanisms 400 and two carrying mechanisms 300; the two dispensing mechanisms 400 are spaced apart along the X direction, and the conveying mechanism 100 is located between the two dispensing mechanisms 400. One carrying mechanism 300 is located in one of the first conveying sections 1 of the conveying mechanism 100, and the other carrying mechanism 300 is located in the other first conveying section 1 of the conveying mechanism 100. One dispensing mechanism 400 is used to dispense glue onto the workpiece on the tray of one of the carrying mechanisms 300, and the other dispensing mechanism 400 is used to dispense glue onto the workpiece on the tray of the other carrying mechanism 300. In this embodiment, the dispensing device 1000 has dual stations and can work simultaneously, thereby improving the working efficiency of the dispensing device 1000.

[0112] In an optional embodiment, the dispensing device 1000 further includes a dispensing auxiliary mechanism 500, which is spaced apart from the conveying mechanism 100 along the Y direction; specifically, the dispensing auxiliary mechanism 500 may include one or more of a dispensing valve, a dispensing weighing component, a glue-wiping gripper component, a glue-blowing needle component, and a glue-spreading component.

[0113] In an embodiment where the dispensing device 1000 includes two dispensing mechanisms 400 and two supporting mechanisms 300, a dispensing auxiliary mechanism 500 is located between the two dispensing mechanisms 400. The dispensing auxiliary mechanism 500 works for both dispensing mechanisms 400 simultaneously, thereby saving space occupied by the dispensing device 1000 and reducing costs.

[0114] The dispensing valve is connected to the dispensing mechanism 400. The dispensing valve controls the opening and closing of the glue channel to precisely control the amount and timing of glue dispensing.

[0115] The dispensing weighing component uses a weight measurement sensor to accurately measure the amount of glue used in each dispensing. Based on the measurement results, the dispensing weighing component can provide real-time feedback and adjust the dispensing amount to ensure that the weight of glue used in each dispensing is consistent.

[0116] The adhesive wiping gripper assembly is used to wipe the dispensing needle of the dispensing assembly 403, remove residual adhesive from the dispensing needle, and prevent the adhesive from solidifying and clogging the dispensing needle, thus affecting the dispensing effect.

[0117] The glue blowing needle assembly is used to calibrate the position of the dispensing needle of the dispensing assembly 403, ensuring that the dispensing needle can accurately align with the target position for dispensing, thereby reducing positional deviation during the dispensing process and improving dispensing accuracy.

[0118] The glue-drawing assembly is used to draw glue lines on the surface of a workpiece, and is suitable for scenarios that require continuous glue application.

[0119] In one specific embodiment, the dispensing device 1000 operates as follows:

[0120] S1. Based on the size of the tray, first adjust the distance between the first conveying component 11 and the second conveying component 12 of the conveying mechanism 100 (this step is not required if the distance between the first conveying component 11 and the second conveying component 12 is adapted to the size of the tray).

[0121] S2, Material tray loading: The material tray carries the workpiece. The material tray is transported from the second conveying section 2 to the first conveying section 1 along the X direction. The first conveying section 1 drives the material tray to move downward along the Z direction so as to place the material tray on the carrying mechanism 300.

[0122] S3. The height of the workpiece is detected by the first detection mechanism and the second detection mechanism, and the position of the dispensing component 403 is adjusted by the drive mechanism 200, the second drive component 401, the third drive component 404, the first rotation component 402 and the second rotation component 405.

[0123] S4, dispensing assembly 403 dispenses adhesive onto the workpiece.

[0124] S5. The workpiece after dispensing adhesive is inspected by a third testing agency (600) to determine whether it is qualified.

[0125] S6. After dispensing, the first conveying section 1 drives the material tray to move upward in the Z direction to lift the material tray from the bearing mechanism 300. The first conveying section 1 then conveys the material tray in the X direction to unload the material tray.

[0126] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
