Description

Technical Field

[0001] The present application relates to the technical field of transportation operations, and in particular to a transfer device, a glue dispensing system and a glue dispensing method. Background Art

[0002] Glue dispensing is commonly used in the existing printed circuit board (PCB) manufacturing process. The PCB glue dispensing operation is to apply or drip glue or viscous liquid material on the PCB surface to a specified fixed position to achieve the bonding, fixing, insulation and protection of components.

[0003] PCBs are usually positioned in carriers. During the transportation of PCBs, the carriers need to be positioned, transported, and paused at fixed points to accurately align the PCBs at the dispensing station. Conventional carrier transportation is circulated in the form of a conveyor line. The conveyor line is provided with a dispensing device for dispensing glue on the PCBs on the carriers. One side of the conveyor line is loaded with carriers without dispensing glue, and the other side of the conveyor line is loaded with carriers with dispensing glue. In order to improve the circulation efficiency of the carriers on the conveyor line, the conveyor line is set as a double-layer structure, that is, the upper layer of the conveyor line is used to transport carriers loaded with PCBs, and the lower layer of the conveyor line is used to transport empty carriers. Transfer devices are arranged at both ends of the conveyor line to realize the conversion of carriers between the upper and lower layers of the conveyor line.

[0004] Usually, the structure of the carrier is designed according to the structural dimensions of the PCB. On the one hand, the carrier can meet the needs of positioning the PCB, and on the other hand, the carrier can be smoothly transported along the conveyor line. When the structural dimensions of the PCB change, especially when the length of the PCB increases, the length of the corresponding carrier also increases. The change in the length of the carrier does not affect its transportation on the upper and lower layers of the conveyor line.

[0043] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0044] Embodiment 1

[0045] This embodiment provides a dispensing system, in which the carrier 11 circulates on a conveyor line to implement dispensing of products on the carrier 11. The products can be diverse, and the products have a need for dispensing. In this embodiment, the products are PCBs.

[0046] The conveyor line includes an upper line 12 and a lower line 13 with opposite conveying directions. The upper line 12 is used to convey the loaded carrier 11, and the lower line 13 is used to convey the empty carrier 11. According to the length requirement of the product, the length of the carrier 11 is greater than the length of the product. When the length of the carrier 11 increases, it does not affect its transportation along the conveying direction of the conveyor line. The length direction of the carrier 11 is consistent with the conveying direction of the conveyor line. However, if the carrier 11 is transferred between the upper line 12 and the lower line 13 of the conveyor line, it is necessary to expand the transfer space at the end of the conveyor line, increase the complexity of the equipment modification, and increase the additional space occupation. This embodiment optimizes the conveyor line equipment to be suitable for the dispensing operation of the product circulating along the conveyor line, which is explained below.

[0047] like Figure 1-Figure 5As shown, a glue dispensing system includes a transfer device 2 arranged at both ends of a conveying line, a lifting device 6 and a glue dispensing device 7 arranged along the conveying line, the lifting device 6 is located below the upper line 12, and the glue dispensing device 7 is located above the upper line 12 and corresponds to the lifting device 6; the transfer device 2 includes a lifting and moving transfer assembly 21, a crimping assembly 31 arranged on the transfer assembly 21, and a limit assembly 41.

[0048] The adapter assembly 21 includes an adapter line 22 arranged in the same direction as the conveyor line, and the conveying direction of the adapter line 22 is consistent with the conveying direction of the conveyor line connected to it, so that the carrier 11 can be transferred from the conveyor line to the adapter line 22; specifically, when the adapter line 22 is raised or lowered to the corresponding lower line 13 position, the conveying direction of the adapter line 22 is the same as the conveying direction of the lower line 13, and the carrier 11 can enter the adapter line 22 from the lower line 13 or the empty carrier 11 can enter the lower line 13 from the adapter line 22; when the adapter line 22 rises to the corresponding upper line 12 position, the transfer conveying direction is the same as the conveying direction of the upper line 12, and the carrier 11 can enter the upper line 12 from the adapter line 22 or enter the adapter line 22 from the upper line 12.

[0049] The crimping assembly 31 includes a rolling element 32 , which acts on the upper surface of the carrier 11 perpendicularly relative to the conveying direction of the adapter line 22 ; the rolling element 32 rolls and crimps the carrier 11 on the adapter line 22 , and the rolling element 32 and the adapter line 22 work together to convey the carrier 11 .

[0050] The rolling element 32 may have an elastic function, and the rolling element 32 may be a driving roller or a driven roller. When the rolling element 32 presses the carrier 11 onto the transfer line 22, the transfer line 22 moves the carrier 11 along the conveying direction, and the rolling element 32 rolls and contacts the carrier 11. The rolling element 32 and the transfer line 22 work together to convey the carrier 11 along the same conveying direction. The rolling element 32 can maintain the balance of the carrier 11 on the conveying line. When the length of the carrier 11 exceeds the transfer line 22, in order to prevent the carrier 11 from tilting or warping on the transfer line 22, the surface of the carrier 11 is rolled and pressed by the rolling element 32, so that the bottom of the carrier 11 can move smoothly on the transfer line 22. The bottom of the carrier 11 has a large frictional force in contact with the transfer line 22. It should be understood that the rolling contact of the rolling element 32 with the carrier 11 does not hinder the carrier 11 from being conveyed along the transfer line 22.

[0051] The limiting assembly 41 includes a blocking member 42, which is located at one end of the adapter line 22 away from the conveying line. Specifically, the blocking member 42 is located in the conveying direction of the adapter line 22 and moves closer to or away from the adapter line 22. The end of the carrier 11 extending out of the adapter line 22 is supported by the blocking member 42.

[0052] When the length of the carrier 11 is greater than the adapter line 22, during the transition of the carrier 11 from the conveying line to the adapter line 22, that is, the adapter line 22 transports the carrier 11 along the first direction, the end of the carrier 11 exceeds the end of the adapter line 22 away from the conveying line, and the end of the carrier 11 is outside the adapter line 22. At this time, the blocking member 42 moves away from the adapter line 22 and supports the end of the carrier 11, playing a supporting role for the carrier 11 to prevent the risk of tilting or falling of the portion of the carrier 11 beyond the adapter line 22; when the carrier 11 is from the conveying line to the adapter line 22, the blocking member 42 moves away from the adapter line 22 and supports the end of the carrier 11, playing a supporting role for the carrier 11, so as to prevent the risk of tilting or falling of the portion of the carrier 11 beyond the adapter line 22; When the delivery line is completely transferred to the adapter line 22, the adapter line 22 suspends transportation and the blocking member 42 stops moving. When the adapter line 22 is connected to the conveying line again, that is, the adapter line 22 transports the carrier 11 along the second direction, and the carrier 11 is required to flow back to the conveying line again, at this time, the blocking member 42 moves synchronously with the adapter line 22, and the blocking member 42 carries the carrier 11. The carrier 11 is conveyed along the adapter line 22 until the carrier 11 is separated from the blocking member 42. The blocking member 42 moves close to the adapter line 22, and the carrier 11 is completely transferred from the adapter line 22 to the conveying line.

[0053] In this embodiment, a crimping assembly 31 is arranged on the adapter assembly 21, and the crimping assembly 31 includes a rolling member 32, which acts on the surface of the carrier 11 perpendicularly relative to the conveying direction of the adapter line 22; the rolling member 32 rolls and crimps the carrier 11 on the adapter line 22, and the rolling member 32 and the adapter line 22 work together to convey the carrier 11. When the length of the carrier 11 is larger than the conveying size of the adapter line 22, the rolling member 32 cooperates with the adapter line 22 to stably position and convey the carrier 11, reducing the risk of the carrier 11 warping or falling. The crimping assembly 31 is arranged on the adapter assembly 21, does not occupy the external space of the adapter device 2, and reduces the complexity of upgrading and modification.

[0054] The present embodiment can also realize the synchronous conveying operation of the adapter line 22 through the blocking member 42, effectively carry the carrier 11 extending from the adapter line 22, prevent the carrier 11 from being detached and damaged, and cooperate with the crimping assembly 31 to enhance the stability of positioning and conveying the carrier 11; the blocking member 42 can be extended to position the carrier 11 close to or away from the adapter line 22, does not occupy the external space of the adapter device 2, and does not need to be modified to expand the volume of the overall adapter device 2, which is easy to implement The maintenance of the adapter device 2 can be used to convey carriers 11 of different lengths and sizes on the conveyor line to realize the dispensing operation of products on different carriers 11, thereby expanding the scope of application of the overall equipment.

[0055] Embodiment 2

[0056] This embodiment optimizes the dispensing system on the basis of the above embodiment, and in particular provides a specific implementation method of a transfer device:

[0057] The adapter device 2 comprises an adapter assembly 21 that can be lifted and lowered, a crimping assembly 31 disposed on the adapter assembly 21 , and a limiting assembly 41 .

[0058] like Figure 1-Figure 5 As shown, the adapter device 2 further includes a bracket 51 and a lifting drive module disposed on the bracket 51 ; the lifting drive module is connected to the adapter component 21 to realize the lifting and moving of the adapter component 21 .

[0059] The bracket 51 can be a frame structure of a square column, and a column 52 is arranged on the bracket 51 in the vertical direction, and a lifting drive module is installed on the column 52; the lifting drive module includes a first guide wheel member 53, a second guide wheel member 54, a connecting belt 55 passing through the first guide wheel member 53 and the second guide wheel member 54, and a driving member pulling the connecting belt 55; a guide wheel plate 56 is arranged on the top of the column 52, and the first guide wheel member 53 is installed on the guide wheel plate 56, and the two ends of the first guide wheel member 53 are respectively axially connected to the guide wheel plate 56 to realize the free rotation of the first guide wheel member 53.

[0060] The guide wheel plate 56 is provided with a belt hole for passing the connecting belt 55, and a driving member is provided below the guide wheel plate 56. The driving end of the driving member is connected to the second guide wheel member 54, one end of the connecting belt 55 is connected to the bottom of the guide wheel plate 56, and the other end of the connecting belt 55 is connected to the adapter assembly 21. The connecting belt 55 passes through the second guide wheel member 54 and the first guide wheel member 53, and the second guide wheel member 54 is hoisted below the first guide wheel member 53 through the connecting belt 55. When the driving member drives the second guide wheel member 54 to rise, the connecting belt 55 between the second guide wheel member 54 and the guide wheel plate 56 is shortened, and the connecting belt 55 between the first guide wheel member 53 and the adapter assembly 21 is extended, thereby realizing the descent of the adapter assembly 21; when the driving member drives the second guide wheel member 54 to descend, the connecting belt 55 between the second guide wheel member 54 and the guide wheel plate 56 is extended, and the connecting belt 55 between the first guide wheel member 53 and the adapter assembly 21 is shortened, thereby realizing the descent of the adapter assembly 21. The lifting drive module is used to realize the lifting action of the adapter assembly 21, and the connecting belt 55 is used to transport the adapter assembly 21. The lifting process is more stable, and the conversion of the smaller driving stroke of the driving member to the larger moving stroke of the adapter assembly 21 can be realized. The efficiency of using the driving member to reach the driving stroke is higher. In this embodiment, the driving member can be a cylinder.

[0061] A guide rail 57 arranged in the vertical direction is installed on the column 52, and a guide plate 58 slidably matched with the guide rail 57 is provided on the guide rail 57. The adapter assembly 21 is installed on the guide plate 58. The adapter assembly 21 follows the lifting plate 73 to rise and fall along the guide rail 57 to achieve smooth lifting and sliding.

[0062] The adapter assembly 21 also includes an adapter seat 23, on which an adapter line 22 is disposed, and the side of the adapter seat 23 is mounted on the guide plate 58. The adapter line 22 is a group of belt lines arranged at a relative interval, and a group of belt lines has a synchronous and unidirectional circulation conveying function; the front and rear parts of the adapter seat 23 are respectively provided with pulleys connected to the belt lines, and the pulleys are driven to rotate to realize the circulation conveying of a group of belt lines. The pulleys can be driven by the driving end of the motor to drive the pulleys to rotate. In this embodiment, the adapter line 22 is arranged in the horizontal direction, and the adapter line 22 is arranged in the same direction as the conveying line.

[0063] The adapter assembly 21 also includes a support plate seat 24 disposed on the adapter seat 23 and located on both sides of the adapter line 22. The crimping assembly 31 is disposed on the support plate seat 24. The crimping assembly 31 also includes a crimping beam 33. The crimping beam 33 is disposed on a group of support plate seats 24 arranged at intervals. The crimping beam 33 is provided with a rolling member 32, which is arranged toward the adapter line 22. The rolling member 32 is driven to move up and down relative to the crimping beam 33. The rolling member 32 can be driven by the driving end of the cylinder to drive the rolling member 32 to move up and down. The rolling member 32 can be a roller, and an elastic member (not shown in the figure) is disposed between the rolling member 32 and the crimping beam 33. The elastic member can be a spring. When the rolling element 32 rolls and contacts the carrier 11, the elastic element can buffer the force of the rolling element 32 descending to contact the carrier 11, thereby protecting the carrier 11. At the same time, it provides a buffer for the combined force of the rolling element 32 and the adapter line 22 to act on the carrier 11, thereby preventing excessive friction of the carrier 11 caused by the rigid contact of the rolling element 32 and affecting the smooth transportation of the carrier 11 by the adapter line 22.

[0064] The crimping beam 33 can be located at the front of the support plate seat 24 close to the conveyor line, or at the middle of the support plate seat 24, or at the rear of the support plate seat 24 away from the conveyor line. This embodiment is described by taking the crimping beam 33 located at the front of the support plate seat 24 close to the conveyor line as an example, so that the crimping assembly 31 and the limiting assembly 41 form a matching relationship to achieve balanced positioning of the carrier 11.

[0065] A group of rolling elements 32 are symmetrically arranged on the crimping beam 33, and a group of rolling elements 32 and a group of conveyor belts are arranged correspondingly in the vertical direction, so that the rolling elements 32 and the conveyor belts can balance the forces on the surface and bottom of the carrier 11 respectively, achieving better positioning and conveying effects.

[0066] The limiting assembly 41 also includes a slide rail 46 disposed on the side of the support plate seat 24. The slide rail 46 is arranged in the horizontal direction. The blocking member 42 is slidably matched with the support plate seat 24 through the slide rail 46. In this embodiment, the support plate seat 24 is an L-shaped structure. The blocking member 42 includes a first blocking portion 43 and a second blocking portion 44 respectively connected to both ends of the first blocking portion 43. The second blocking portion 44 is slidably connected to the support plate seat 24. Specifically, the second blocking portion 44 is slidably matched with the support plate seat 24 through the slide rail 46. The first blocking portion 43 is located between a group of support plate seats 24. The second blocking portion 44 is driven to move along the slide rail 46. The second blocking portion 44 can be driven by connecting the second blocking portion 44 through the driving end of the cylinder.

[0067] In this embodiment, the first blocking portion 43 and the second blocking portion 44 are connected to form a U-shaped structure, which does not interfere with the transport of the carrier 11 along the transfer line 22 .

[0068] The first blocking portion 43 corresponds to the adapter line 22. When the carrier 11 is transported along the adapter line 22, the end of the carrier 11 corresponds to the first blocking portion 43. The first blocking portion 43 may or may not abut against the end of the carrier 11. The first blocking portion 43 includes a blocking body and a support portion 45 arranged at the bottom of the blocking body. The support portion 45 is respectively connected to the blocking body and the second blocking portion 44. The support portion 45 is aligned with the adapter line 22 in the horizontal direction. When the carrier 11 is transported from the adapter line 22 and extends out of the adapter line 22, the end of the carrier 11 is supported by the support portion 45, thereby improving the stability of the carrier 11 on the adapter line 22.

[0069] In this embodiment, the support part 45 is a triangular structure, the blocking body and the second blocking part 44 are vertically connected, and the support part 45 is arranged at the inner corner where the blocking body and the second blocking part 44 meet, so as to improve the structural stability of the support part 45, the blocking body and the second blocking part 44, and achieve the purpose of stably supporting the carrier 11.

[0070] The front end and the rear end of the adapter 23 are respectively connected to sensors (not shown in the figure), and the sensors are used to detect the position of the carrier 11 transported along the adapter line 22. Specifically, the front end of the adapter 23 is provided with a first sensor, and the first sensor corresponds to the front end of the adapter line 22, and is used to detect the initial position of the carrier entering the adapter line 22. The rear end of the adapter 23 is provided with a second sensor, and the second sensor is aligned with the first blocking portion 43, and is used to detect the terminal position of the carrier entering the adapter line 22, that is, the first end of the carrier and the first blocking portion 43. 3 abuts against the position; when the carrier 11 enters the transfer line 22 from the conveyor line, the transfer line 22 conveys the carrier 11 along the first direction, and when the second sensor detects that the carrier 11 reaches the rear end of the transfer line 22, the first sensor confirms the position of the front end of the transfer line 22 where the carrier 11 is located and continues to detect, indicating that the second end of the carrier has not yet entered the transfer line 22, and the rolling element 32 rolls and presses on the surface of the carrier 11. As the transfer line 22 continues to convey the carrier 11, the carrier 11 extends beyond the rear end of the transfer line 22, and the blocking element 42 rotates synchronously The connecting line 22 moves and carries the carrier 11, and the blocking member 42 moves away from the connecting line 22 until the first sensor detects the second end of the carrier 11, indicating that the carrier has completely entered the connecting line 22, and the connecting line 22 and the blocking member 42 are suspended; when the carrier 11 enters the conveying line from the connecting line 22, the connecting line 22 conveys the carrier 11 along the second direction. When the first sensor detects the front end of the connecting line 22 where the carrier 11 is located, the second sensor confirms the position of the rear end of the connecting line 22 where the carrier 11 is located and continues to detect. As the connecting line 22 continues to convey The carrier 11 is sent and enters the conveyor line. At the same time, the blocking member 42 moves synchronously with the transfer line 22 and carries the carrier 11. The blocking member 42 approaches the transfer line 22 until the second sensor detects the first end of the carrier 11, that is, the carrier 11 is completely located on the transfer line 22. The blocking member 42 pauses, and the rolling member 32 resets to move away from the surface of the carrier 11. The carrier 11 continues to be transported to the conveyor line along the transfer line 22.

[0080] Embodiment 4

[0081] This embodiment provides a dispensing method, which is applied to the dispensing system in the above embodiment, and the method includes:

[0082] The adapter line 22 is controlled to dock with the first conveying line in a horizontal direction, and the adapter line 22 conveys the carrier 11 in a first direction, where the first direction is the direction in which the carrier 11 is conveyed from the conveying line to the adapter line 22;

[0083] The first conveying line is the lower line 13 . When the carrier 11 is conveyed to a designated position along the lower line 13 , the adapter line 22 is controlled to descend so as to achieve docking between the adapter line 22 and the lower line 13 .

[0084] Detect the position information of the carrier 11 on the adapter cable 22. When it is detected that the first end of the carrier 11 reaches the first preset position of the adapter cable 22, continue detecting until it is detected that the first end of the carrier 11 reaches the second preset position of the adapter cable 22, and the second end of the carrier 11 is not detected to reach the first preset position of the adapter cable 22.

[0085] Among them, the end of the carrier 11 from the conveyor line toward the transfer line is the first end, and the end of the carrier 11 from the transfer line toward the conveyor line is the second end; the first preset position is the end of the transfer line 22 close to the conveyor line, and the second preset position is the end of the transfer line 22 away from the conveyor line. It should be understood that the first sensor can detect whether the carrier 11 reaches the first preset position, and the second sensor can detect whether the carrier 11 reaches the second preset position. The second preset position corresponds to the initial position of the blocking member 42, that is, the position of the blocking member 42 close to the transfer line 22; the above-mentioned first preset position where the second end of the carrier 11 is not detected to reach the transfer line 22 indicates that the length of the carrier 11 exceeds the length of the transfer line 22, and the first end of the carrier 11 moves on the transfer line 22 beyond the end of the transfer line 22, and the subsequent steps need to be carried out through the cooperation of the rolling member and the blocking member.

[0086] Detecting the position information of the carrier 11 on the transfer line 22 also includes: when it is detected that the first end of the carrier 11 reaches the first preset position of the transfer line 22, the detection is continued until the second end of the carrier 11 reaches the first preset position of the transfer line 22, and the first end of the carrier 11 is not detected to reach the second preset position of the transfer line 22, the transfer line 22 is paused, the transfer line 22 is docked with the second conveyor line, and the transfer line 22 can convey the carrier 11 along the second direction. It means that the length of the carrier 11 is smaller than the length of the transfer line 22, and the transfer line 22 can normally realize the transfer operation without the need for matching rolling parts and blocking parts.

[0087] Detecting the position information of the carrier 11 on the transfer line 22 also includes, when it is detected that the first end of the carrier 11 reaches the first preset position of the transfer line 22, continuing the detection until it is detected that the second end of the carrier 11 reaches the first preset position of the transfer line 22, and detecting that the first end of the carrier 11 reaches the second preset position of the transfer line 22, the transfer line 22 is paused, the transfer line 22 is docked with the second conveyor line, and the transfer line 22 can convey the carrier 11 along the second direction. It means that the length dimension of the carrier 11 is equal to the length dimension of the transfer line 22, and the transfer line 22 can normally realize the transfer operation without the need for matching rolling parts and blocking parts.

[0088] The roller 32 is controlled to roll and contact the surface of the carrier 11. The roller 32 and the adapter line 22 work together to transport the carrier 11 along the first direction. At the same time, the blocking member 42 supports the first end of the carrier 11 and controls it to move away from the adapter line 22 at the same speed until it is detected that the second end of the carrier 11 reaches the first preset position of the adapter line 22, and the blocking member 42 and the adapter line 22 are controlled to pause.

[0089] Among them, the first direction is the conveying direction from the conveyor line toward the transfer line 22; the rolling element 32 and the transfer line 22 work together to convey the carrier 11 along the first direction, so that the carrier 11 can completely enter the transfer line 22 from the conveyor line, and the blocking element 42 has a supporting effect on the first end of the carrier 11.

[0090] The control adapter line 22 is connected to the second conveying line in the horizontal direction.

[0091] The second conveyor line is the upper line 12 . When the carrier 11 needs to be transferred from the first conveyor line to the second conveyor line, the transfer line 22 is controlled to rise so as to achieve the connection between the transfer line 22 and the upper line 12 .

[0092] The control rolling element 32 and the transfer line 22 cooperate to transport the carrier 11 along the second direction, while the blocking element 42 supports the first end of the carrier 11 and controls the first end of the carrier 11 to move close to the transfer line 22 at the same speed.

[0093] The second direction is the conveying direction from the transfer line 22 toward the conveying line, and the blocking member 42 and the transfer line 22 move at the same speed to gradually convey the carrier 11 to the conveying line.

[0094] The adapter line 22 is controlled to dock with the second conveyor line in the horizontal direction, and then it also includes detecting that the second end of the carrier 11 is located at the first preset position of the adapter line 22; it is used to determine the initial position of the carrier 11 when the adapter line 22 is docked to the upper line 12, ensuring that the carrier 11 is not displaced during the rising process of the adapter line 22.

[0095] The position information of the carrier 11 on the adapter line 22 is detected. When it is detected that the first end of the carrier 11 reaches the second preset position of the adapter line 22, the blocking member 42 is controlled to pause and the rolling member 32 is reset.

[0096] At this time, the first end of the carrier 11 is already located on the transfer line 22 , and a portion of the carrier 11 has entered the conveyor line, and the blocking member 42 and the rolling member 32 do not need to act on the carrier 11 .

[0097] When it is detected that the first end of the carrier 11 reaches the first preset position of the adapter line 22 , the second conveyor line is controlled to convey the carrier 11 to the glue dispensing device 7 .

[0098] Among them, it is detected that the first end of the carrier 11 reaches the first preset position of the adapter line 22, indicating that the carrier 11 is about to leave the adapter line 22, and the second conveyor line is controlled to convey the carrier 11 to the glue dispensing device 7, and the glue dispensing device 7 performs glue dispensing on the product on the carrier 11.

[0099] The products after the glue dispensing treatment are unloaded from the carrier 11, and the products without glue dispensing are reset on the carrier 11, and the carrier 11 circulates along the second conveyor line again, and the carrier 11 circulates from one end of the second conveyor line to the other end thereof;

[0100] Control the other transfer line 22 to dock with the second conveying line in the horizontal direction, and the other transfer line 22 conveys the carrier 11 in the first direction;

[0101] Detect the position information of the carrier 11 on the other adapter line 22. When it is detected that the first end of the carrier 11 reaches the first preset position of the other adapter line 22, continue detecting until it is detected that the first end of the carrier 11 reaches the second preset position of the other adapter line 22, and the second end of the carrier 11 is not detected to reach the first preset position of the other adapter line 22.

[0102] The roller 32 is controlled to roll and contact the surface of the carrier 11. The roller 32 and the other adapter line 22 work together to transport the carrier 11 along the first direction. At the same time, the blocking member 42 is controlled to carry the first end of the carrier 11 and move away from the other adapter line 22 at the same speed until it is detected that the second end of the carrier 11 reaches the first preset position of the other adapter line 22, and the blocking member 42 and the other adapter line 22 are controlled to pause.

[0103] The control adapter line 22 is connected to the first conveying line in the horizontal direction.

[0104] The control rolling element 32 and the other transfer line 22 cooperate to transport the carrier 11 along the second direction, while the blocking element 42 supports the first end of the carrier 11 and controls the first end 42 to move closer to the other transfer line 22 at the same speed.

[0105] The position information of the carrier 11 on the other adapter line 22 is detected. When it is detected that the first end of the carrier 11 reaches the second preset position of the other adapter line 22, the blocking member 42 is controlled to pause and the rolling member 32 is reset.

[0106] When it is detected that the first end of the carrier 11 reaches the first preset position of another transfer line 22, the first conveyor line is controlled to convey the carrier 11, and the above steps are repeated.

[0107] In this embodiment, the carrier 11 can be transported from the first conveyor line to the transfer line 22, and the carrier 11 can be transported from the transfer line 22 to the second conveyor line. Similarly, the carrier 11 can also be transported from the second conveyor line to another transfer line 22, and the carrier 11 can be transported from another transfer line 22 to the first conveyor line. Therefore, arranging the lifting and transfer components 21 at both ends of the double-layer conveyor line can realize the circulation of the carrier 11 in the double-layer conveyor line. The above-mentioned dispensing method can accurately detect the position information of the carrier, control the blocking parts and the rolling parts to cooperate in positioning the carrier, and realize the balanced transportation of the carrier along the transfer line to avoid the problems of warping and falling.
