Abstract
Description
Technical Field
[0001] This application relates to the field of semiconductor manufacturing technology, and in particular to a handling device and handling method. Background Technology
[0002] Semiconductor memory is an information storage device that uses semiconductor media. Commonly used memory modules, USB flash drives, and solid-state drives all fall under the category of memory. Currently, the industry designs, manufactures, and packages volatile memory chips and non-volatile memory chips.
[0003] As competition in the semiconductor industry intensifies, the demands on chip testing efficiency are also increasing. To improve testing efficiency, the number of chips tested at a time should be as high as possible. However, the specifications of the chip trays to be tested (hereinafter referred to as loading trays) are often inconsistent with those of the testing area trays (hereinafter referred to as T-Trays). In traditional chip testing equipment, chips are temporarily stored and unloaded through various T-Trays during the process from loading to testing. Each T-Tray is made with different specifications due to industry supplier limitations. Therefore, the range of motion of the handling robot is limited by the specifications of the testing area T-Trays and the customer's loading trays, which inevitably affects the handling efficiency and the complexity of the equipment. Summary of the Invention

[0045] Combination Figures 1 to 10 This application discloses a conveying device 100, which is used to convey products 700 from a loading tray 200 to a testing tray 400 for loading, and to convey products 700 that have been tested by a testing device (not shown) from the testing tray 400 to a receiving tray 600 for unloading. The product spacing between the loading tray 200 and the testing tray 400, and between the receiving tray 600 and the testing tray 400, is different in both the X-direction and Y-direction. The X-direction and Y-direction are set at an angle; the following description assumes that the X-direction and Y-direction are perpendicular.
[0046] Please see Figures 1 to 4 In this embodiment, such as Figure 1 As shown, the loading tray 200 and the receiving tray 600 have the same row and column arrangement, which is 20 rows and 8 columns. The product spacing in the X direction (hereinafter referred to as column spacing) is X1, and the product spacing in the Y direction (hereinafter referred to as row spacing) is Y1. Figure 2 As shown, the first buffer disk 300 is 4 rows and 16 columns, with a column spacing of X2 and a row spacing of Y1. Figure 3 As shown, the detection tray 400 is 16 rows and 16 columns, with a column spacing of X2 and a row spacing of Y2. Figure 4 As shown, the second buffer tray 500 has 8 rows and 8 columns, with a column spacing of X1 and a row spacing of Y2. The following description of the conveying device 100 and conveying method will be based on the above specifications of the loading tray 200, the first buffer tray 300, the detection tray 400, the second buffer tray 500, and the receiving tray 600.
[0047] Please see Figures 5 to 9 The conveying device 100 provided in one embodiment of this application includes a body, a dual-drive mechanism 170 disposed on the body, and a plurality of variable-pitch manipulators, which are spaced apart on the body. Products 700 flow between adjacent variable-pitch manipulators, and the multiple manipulators collectively define the product flow path. Each variable-pitch manipulator is connected to the dual-drive mechanism 170 to move along the product flow path under the drive of the dual-drive mechanism 170. Among the multiple variable-pitch manipulators, at least one manipulator can change the spacing of the products 700 along the X-direction, and at least another manipulator can change the spacing of the products 700 along the Y-direction, thereby changing the spacing of the products 700 in the X and Y directions during the flow of the products 700. Figure 9 and Figure 10 As shown, each variable-pitch robot includes a variable-pitch assembly 160 and multiple pickup elements 165. The variable-pitch assembly 160 is connected to the dual-drive mechanism 170, and the pickup elements 165 are used to pick up the product 700. In this embodiment, the pickup element 165 is a suction nozzle.
[0048] like Figure 5As shown, according to some embodiments of this application, optionally, a plurality of variable-pitch manipulators, some of which are variable-pitch manipulators, jointly constitute a loading manipulator for transporting product 700 from the loading tray 200 to the inspection tray 400, thereby completing the loading. The loading manipulator can sequentially transport product 700 between a first position, a second position, and a third position, changing the X-axis and Y-axis spacing during the transport process. In this embodiment, when product 700 is in the first position, it is located within the loading tray 200; when product 700 is in the second position, it is located within the first buffer tray 300; and when product 700 is in the third position, it is located within the inspection tray 400, so that the inspection device can inspect product 700.
[0049] like Figure 5 As shown, the loading robot includes a first variable-pitch robot 110 and a second variable-pitch robot 120. The first variable-pitch robot 110 moves between a first position and a second position, and is used to change the product spacing X1 to a first target spacing X2. Figure 1 and Figure 2 As shown, the loading tray 200 has 20 rows and 8 columns, with a column spacing of X1 and a row spacing of Y1. The first buffer tray 300 has 4 rows and 16 columns, with a column spacing of X2 and a row spacing of Y1. During the process of the first variable-pitch robot 110 moving the product 700 from the loading tray 200 to the first buffer tray 300, the product spacing in the X direction is changed from X1 to X2 during the moving process.
[0050] like Figure 1 and Figure 2 As shown, the loading tray 200 has 20 rows and 8 columns, and the first buffer tray 300 has 4 rows and 16 columns. In this embodiment, the picking components 165 of the first variable-pitch robot 110 are arranged in a 4×8 configuration, i.e., 4 rows and 8 columns or 4 columns and 8 rows. The products 700 from the loading tray 200 are placed onto the first buffer tray 300 in a 4×8 layout. Since the first buffer tray 300 has 4 rows and 16 columns, and the picking components 165 of the first variable-pitch robot 110 are arranged in a 4×8 configuration, the first variable-pitch robot 110 needs to handle the products twice to fill the first buffer tray 300.
[0051] The second variable-pitch robot 120 moves between a second position and a third position, and is used to change the product spacing Y1 to a second target spacing Y2. For example... Figure 2 As shown, the first buffer disk has a column spacing of X2 and a row spacing of Y1. (The last sentence appears to be incomplete and possibly refers to a different data point.) Figure 3 As shown, the column spacing of the inspection tray 400 is X2, and the row spacing is Y2. The second variable-pitch robot 120 moves between the second position and the third position, so that the product 700 is transported from the first buffer tray 300 to the inspection tray 400, and the product spacing in the Y direction is changed from Y1 to Y2 during the transport process.
[0052] like Figure 2 and Figure 3 The first buffer tray 300 has a 4-row, 16-column layout, the detection tray 400 has a 16-row, 16-column layout, and the pickup parts 165 of the second variable-pitch robot 120 are arranged in a 2×16 configuration (either 2 rows, 16 columns or 2 columns, 16 rows). The products 700 from the first buffer tray 300 are placed onto the detection tray 400 in a 2×16 layout. Because the detection tray 400 has a 16-row, 16-column layout and the pickup parts 165 of the second variable-pitch robot 120 are arranged in a 2×16 configuration, the second variable-pitch robot 120 needs to perform 8 handling operations to fill the detection tray 400.
[0053] like Figure 5 As shown, among the multiple variable-pitch manipulators, another group of variable-pitch manipulators together form a receiving manipulator, used to transport product 700 from the inspection tray 400 to the receiving tray 600, thus completing the receiving process. The receiving manipulator can sequentially transport product 700 between the third, fourth, and fifth positions, changing the X-axis and Y-axis spacing during the transport process. Specifically, when product 700 is in the third position, it is located within the inspection tray 400, but the inspection has already been completed; when product 700 is in the fourth position, it is located within the second buffer tray 500; and when product 700 is in the fifth position, it is located within the receiving tray 600. During the receiving process of transporting product 700 from the inspection tray 400 to the receiving tray 600, the row and column spacing are changed, allowing product 700 to be smoothly transported from the inspection tray 400, where the row and column spacing differs from that of the receiving tray 600, to the receiving tray 600, thus completing the receiving process.
[0054] The receiving robot includes a third variable-pitch robot 130 and a fourth variable-pitch robot 140. The third variable-pitch robot 130 moves between a third position and a fourth position, and is used to change the first target spacing X2 to the product spacing X1. Figure 3 As shown, the detection tray 400 is 16 rows and 16 columns, with a column spacing of X2 and a row spacing of Y2. Figure 4 As shown, the second buffer tray 500 has 8 rows and 8 columns, with a column spacing of X1 and a row spacing of Y2. The third variable-pitch robot 130 moves between the third and fourth positions to transport the product 700 from the inspection tray 400 to the second buffer tray 500, and changes the product spacing in the X direction from X2 to X1 during the transport process.
[0055] like Figure 3 and Figure 4As shown, the inspection tray 400 has 16 rows and 16 columns, and the second buffer tray 500 has 8 rows and 8 columns. In this embodiment, the pickup components 165 of the third variable-pitch robot 130 are arranged in a 4×8 configuration, i.e., 4 rows and 8 columns or 4 columns and 8 rows. The products 700 from the inspection tray 400 are placed onto the second buffer tray 500 in a 4×8 layout. Since the second buffer tray 500 has 8 rows and 8 columns, and the pickup components 165 of the third variable-pitch robot 130 are arranged in a 4×8 configuration, the third variable-pitch robot 130 needs to perform two handling operations to fill the second buffer tray 500.
[0056] Please see Figure 5 , Figure 7 and Figure 8 According to some embodiments of this application, optionally, the conveying device 100 further includes a feeding and receiving device 180 for placing the feeding tray 200, the first buffer tray 300, the detection tray 400, the second buffer tray 500, and the receiving tray 600, and enabling the first buffer tray 300 to move between the first variable-pitch robot 110 and the second variable-pitch robot 120, the detection tray 400 to move between the second variable-pitch robot 120, the detection device, and the third variable-pitch robot 130, and the second buffer tray 500 to move between the third variable-pitch robot 130 and the fourth variable-pitch robot 140.
[0057] According to some embodiments of this application, optionally, there are multiple first buffer trays 300, corresponding respectively to the first variable-pitch robot 110 and the second variable-pitch robot 120. The multiple first buffer trays 300 are located in the feeding and receiving device 180, which is capable of exchanging the positions of the first buffer tray 300 corresponding to the first variable-pitch robot 110 and the first buffer tray 300 corresponding to the second variable-pitch robot 120. Preferably, there are two first buffer trays 300, each corresponding to the first variable-pitch robot 110 and the second variable-pitch robot 120, allowing the first variable-pitch robot 110 and the second variable-pitch robot 120 to operate independently without interference, thereby improving the efficiency of variable-pitch handling of the product 700.
[0058] When the first buffer tray 300 of the first variable-pitch robot 110 is filled with products 700, the first buffer tray 300 corresponding to the first variable-pitch robot 110 is full, while the first buffer tray 300 corresponding to the second variable-pitch robot 120 is empty. The receiving device 180 controls the first buffer tray 300 corresponding to the first variable-pitch robot 110 and the first buffer tray 300 corresponding to the second variable-pitch robot 120 to exchange positions, so that the first buffer tray 300 filled with products 700 is moved to the position of the second variable-pitch robot 120, allowing the second variable-pitch robot 120 to continue picking up products 700. The empty first buffer tray 300, whose products 700 have been taken by the second variable-pitch robot 120, is then moved to the position of the first variable-pitch robot 110, so that the first variable-pitch robot 110 can continue to place products 700 into the corresponding first buffer tray 300.
[0059] According to some embodiments of this application, optionally, there are multiple second buffer trays 500, corresponding respectively to the third variable-pitch robot 130 and the fourth variable-pitch robot 140. The multiple second buffer trays 500 are located in the feeding and receiving device 180, which is capable of exchanging the positions of the second buffer tray 500 corresponding to the third variable-pitch robot 130 and the second buffer tray 500 corresponding to the fourth variable-pitch robot 140. Preferably, there are two second buffer trays 500 between each third variable-pitch robot 130 and the fourth variable-pitch robot 140, with the two second buffer trays 500 corresponding to the third variable-pitch robot 130 and the fourth variable-pitch robot 140 respectively, so that the third variable-pitch robot 130 and the fourth variable-pitch robot 140 can operate independently without interference, thereby improving the efficiency of variable-pitch handling of the product 700.
[0060] like Figure 8 As shown, when the second buffer tray 500 of the third variable-pitch robot 130 is filled with products 700, the receiving device 180 controls the second buffer tray 500 of the third variable-pitch robot 130 to exchange positions with the second buffer tray 500 of the fourth variable-pitch robot 140, so that the second buffer tray 500 filled with products 700 is moved to the position of the fourth variable-pitch robot 140, allowing the fourth variable-pitch robot 140 to continue picking up products 700. The empty second buffer tray 500, whose products 700 have been taken by the fourth variable-pitch robot 140, is then moved to the position of the third variable-pitch robot 130, allowing the third variable-pitch robot 130 to continue placing products 700 into the corresponding second buffer tray 500.
[0061] According to some embodiments of this application, optionally, the number of third variable-pitch manipulators 130 is at least two, and the at least two third variable-pitch manipulators 130 are arranged at intervals along the X direction, and the movement path range of the fourth variable-pitch manipulator 140 can cover the arrangement range of the at least two third variable-pitch manipulators 130. For example... Figure 3 As shown, the detection tray 400 is 16 rows and 16 columns, with a column spacing of X2 and a row spacing of Y2. Figure 4 As shown, the second buffer disk 500 is 8 rows and 8 columns, with a column spacing of X1 and a row spacing of Y2. In this embodiment, as... Figure 1 As shown, there are two third variable-pitch robots 130. These two robots transport products 700 located in different areas of the same inspection tray 400 to different second buffer trays 500, changing the product spacing in the X direction from X2 to X1 during the transport process. Preferably, one of the two third variable-pitch robots 130 transports the products 700 from the right half (16 rows, 8 columns) of the inspection tray 400 to the corresponding second buffer tray 500, and the other transports the products 700 from the left half (16 rows, 8 columns) of the inspection tray 400 to the corresponding second buffer tray 500.
[0062] The fourth variable-pitch robot 140 moves between the fourth and fifth positions. The fourth variable-pitch robot 140 is used to change the second target spacing Y2 to the product spacing Y1. For example... Figure 4 As shown, the second buffer disk 500 is 8 rows and 8 columns, with a column spacing of X1 and a row spacing of Y2. Figure 1 As shown, the receiving tray 600 has 20 rows and 8 columns, with a column spacing of X1 and a row spacing of Y1. The fourth variable-pitch robot 140 moves between the fourth and fifth positions to transport the product 700 from the second buffer tray 500 to the receiving tray 600, and changes the product spacing in the Y direction from Y2 to Y1 during the transport process.
[0063] like Figure 1 and Figure 4 As shown, the second buffer tray 500 has an 8-row, 8-column layout, and the receiving tray 600 has a 20-row, 8-column layout. In this embodiment, the picking components 165 of the fourth variable-pitch robot 140 are arranged in a 4×8 configuration, i.e., 4 rows and 8 columns or 4 columns and 8 rows. The products 700 from the second buffer tray 500 are placed onto the receiving tray 600 in a 4×8 layout. Since the receiving tray 600 has a 20-row, 8-column layout, and the picking components 165 of the fourth variable-pitch robot 140 are arranged in a 4×8 layout, the fourth variable-pitch robot 140 needs to perform 5 handling operations to fill the receiving tray 600.
[0064] Optionally, to improve material collection efficiency, the picking part 165 of the fourth variable pitch robot 140 can be replaced with a 4-row, 14-column configuration, and the receiving tray 600 can also be changed to a 20-row, 14-column configuration.
[0065] In this embodiment, the X-axis and Y-axis spacing of the loading robot at the initial handling position (i.e., the first position) are the same as the X-axis and Y-axis spacing of the receiving robot at the end handling position (i.e., the fifth position). Accordingly, the loading tray 200 and the receiving tray 600 have the same row and column arrangement, which is 20 rows and 8 columns, with the product spacing in the X-axis being X1 and the product spacing in the Y-axis being Y1.
[0066] According to some embodiments of this application, optionally, the spacing of the plurality of pickups 165 in the first variable-pitch robot 110 along the Y direction is the same as the product spacing Y1 at the first position. That is, during the process of the first variable-pitch robot 110 transporting the product 700 from the loading tray 200 to the first buffer tray 300, the spacing of adjacent pickups 165 in the Y direction is consistent with and remains unchanged from the product spacing within the loading tray 200 and the first buffer tray 300. The spacing of the plurality of pickups 165 in the second variable-pitch robot 120 along the X direction is the same as the first target spacing X2 at the second position. That is, during the process of the second variable-pitch robot 120 transporting the product 700 from the first buffer tray 300 to the detection tray 400, the spacing of adjacent pickups 165 along the X direction is consistent with and remains unchanged from the product spacing within the first buffer tray 300 and the detection tray 400. In the third variable-pitch robot 130, the spacing of adjacent pickups 165 along the Y direction is the same as the second target spacing Y2 at the third position. That is, during the process of the third variable-pitch robot 130 transporting the product 700 from the detection tray 400 to the second buffer tray 500, the spacing of adjacent pickups 165 in the Y direction is consistent with and remains unchanged from the product spacing within the detection tray 400 and the second buffer tray 500. In the fourth variable-pitch robot 140, the spacing of multiple pickups 165 along the X direction is the same as the product spacing X at the fourth position. That is, during the process of the fourth variable-pitch robot 140 transporting the product 700 from the second buffer tray 500 to the receiving tray 600, the spacing of adjacent pickups 165 in the X direction is consistent with and remains unchanged from the product spacing within the second buffer tray 500 and the receiving tray 600.
[0067] like Figure 9 and Figure 10 As shown, the pitch-changing assembly 160 has a plurality of guide rails 1621 spaced apart along a first direction (X or Y), and the spacing between any adjacent guide rails 1621 gradually increases along a second direction. The plurality of guide rails 1621 are independently configured, and adjacent guide rails 1621 do not interfere with each other. Each guide rail 1621 corresponds to a pickup 165, and a portion of the pickup 165 extends into the corresponding guide rail 1621. The plurality of pickups 165 are configured to move along their corresponding guide rails 1621 in response to the drive of the pitch-changing assembly 160, thereby changing the spacing between any adjacent pickups 165 along the Y or X direction; wherein the second direction is angled relative to the first direction.
[0068] When the first direction is X, the pickup 165 can achieve variable product spacing in the X direction. For example... Figure 10 As shown, in the second direction, the spacing between adjacent guide rails 1621 is X1 at one end and X2 at the other end. (See also...) Figure 9 and Figure 10 When the pickup 165 slides along the corresponding guide slide 1621, the distance between adjacent pickups 165 changes from X1 to X2. Reversing the distance between the guide slides 1621, or moving the pickups 165 in the opposite direction, can change the distance between adjacent pickups 165 from X2 to X1. Correspondingly, when the first direction is set to the Y direction, the pickup 165 can achieve product spacing variation in the Y direction. The principle of product spacing variation in the Y direction is similar to the principle described above and will not be elaborated here.
[0069] like Figure 9 and Figure 10 As shown, according to some embodiments of this application, optionally, the pitch control assembly 160 includes a guide plate 162, a lateral slide bar 161, and a guide 163. It is understood that the pitch control assembly 160 also includes a pitch drive 164 that provides kinetic energy for pitch control; the pitch drive 164 is connected to the guide plate 162 to move the guide plate 162 relative to the pickup member 165. The guide plate 162 is configured with a plurality of guide holes spaced apart along a first direction, each guide hole forming a guide rail 1621. For example... Figure 9 As shown, the transverse slide bar 161 is arranged laterally. In this embodiment, the pitch-changing assembly 160 is provided with a bracket, which supports the guide plate 162, the transverse slide bar 161, and the guide 163. The transverse slide bar 161 is laterally connected to the bracket. Multiple guides 163 are slidably connected to the transverse slide bar 161 and can all move relative to the transverse slide bar 161 in a first direction. One end of each guide 163 is connected to a pickup 165, and the other end extends into a guide hole. The guide plate 162 can move in the vertical direction, driving the guide 163 to move relative to the transverse slide bar 161 within the guide hole, thereby changing the spacing between any two adjacent pickups 165.
[0070] In other embodiments, the guide slide 1621 may also be a sliding track fixedly connected to the guide plate 162, in which case the pickup 165 is slidably connected to the sliding track.
[0071] When the transverse slide bar 161 is set along the X direction, the pickup element 165 can achieve variable product spacing in the X direction. For example... Figure 10 As shown, in the vertical direction, the distance between adjacent guide rails 1621 is X1 at one end and X2 at the other. Please refer to [link / reference]. Figure 9 and Figure 10When the guide plate 162 moves upward in the vertical direction, each guide 163 slides along its corresponding guide slide 1621 in the vertical direction, causing each guide 163 to slide relative to the transverse slide bar 161 in the transverse direction. This changes the spacing between adjacent guides 163, thereby changing the spacing between adjacent pickups 165 from X1 to X2. Reversing the installation of the guide plate 162, or moving the guide plate 162 downward in the vertical direction, can change the spacing between adjacent pickups 165 from X2 to X1. Correspondingly, when the transverse slide bar 161 is set along the Y direction, the product spacing between adjacent pickups 165 can be varied in the Y direction. The principle of product spacing variation in the Y direction is similar to the principle described above and will not be elaborated here.
[0072] According to some embodiments of this application, optionally, among the multiple variable-pitch manipulators, some variable-pitch manipulators also include a crossbeam assembly 150. The crossbeam assembly 150 is connected to the variable-pitch assembly 160 and to the dual-drive mechanism 170. The crossbeam assembly 150 has a built-in motor and a slider. The variable-pitch assembly 160 is mounted on the slider. The motor drives the variable-pitch assembly 160 and the pickup 165 to move laterally with the slider. At the same time, the crossbeam assembly 150 also includes a vertical motor, which is used to drive the pickup 165 to move vertically to pick up materials. In this embodiment, the first variable-pitch manipulator 110, the third variable-pitch manipulator 130, and the fourth variable-pitch manipulator 140 all include a crossbeam assembly 150.
[0073] The dual-drive mechanism 170 includes a first dual-drive component 171, a second dual-drive component 172, a third dual-drive component 173, and a fourth dual-drive component 174, which are respectively connected to the first variable-pitch robot 110, the second variable-pitch robot 120, the third variable-pitch robot 130, and the fourth variable-pitch robot 140. Taking the first variable-pitch robot 110 and the first dual-drive component 171 as an example, the crossbeam assembly 150 of the first variable-pitch robot 110 is connected to the first dual-drive component 171, and the variable-pitch component 160 is mounted on the crossbeam assembly 150. The first dual-drive component 171 controls the movement of the crossbeam assembly 150, thereby enabling the first variable-pitch robot 110 to move between the loading tray 200 and the first buffer tray 300 under the control of the first dual-drive component 171. Similarly, the second dual-drive unit 172 controls the second variable-pitch robot 120 to move between the first buffer tray 300 and the detection tray 400, the third dual-drive unit 173 controls the third variable-pitch robot 130 to move between the detection tray 400 and the second buffer tray 500, and the fourth dual-drive unit 174 controls the fourth variable-pitch robot 140 to move between the second buffer tray 500 and the receiving tray 600.
[0074] Optionally, according to some embodiments of this application, the machine body is equipped with an alarm component. Preferably, the alarm component is disposed between adjacent variable-pitch manipulators to avoid motion interference between adjacent variable-pitch manipulators during handling. The alarm component includes an interference detection element and an alarm. The interference detection element is used to detect the distance between adjacent variable-pitch manipulators. In this embodiment, the interference detection element adopts a machine motion interference detection system, which can collect and plan trajectory data of the variable-pitch manipulators. The specific structure and program are not described in detail here. The alarm is used to issue an alarm when the detection distance detected by the interference detection element is lower than the alarm distance.
[0075] This application also provides a handling method based on the above-described handling device 100, the handling method comprising the following steps:
[0076] The first variable-pitch robot 110 is controlled to move the arrayed products 700 from the first position to the second position. During the moving process, the product spacing X1 in the X direction between multiple products 700 is changed to the first target spacing X2. During the process of the first variable-pitch robot 110 moving the products 700 from the loading tray 200 (X1, Y1) to the first buffer tray 300 (X2, Y1), the product spacing in the X direction is changed from X1 to X2. At this time, the products 700 are located in the first buffer tray 300 with a column spacing of X2 and a row spacing of Y1.
[0077] Subsequently, the second variable-pitch robot 120 transports the arrayed products 700 from the second position to the third position. During the transport process, the product spacing Y1 along the Y direction between multiple products 700 is changed to the second target spacing Y2. The second variable-pitch robot 120 moves between the second and third positions, so that the products 700 are transported from the first buffer tray 300 (X2, Y1) to the detection tray 400 (X2, Y2). During the transport process, the product spacing in the Y direction is changed from Y1 to Y2. At this time, the products 700 are located in the detection tray 400 with a column spacing of X2 and a row spacing of Y2.
[0078] Subsequently, the product 700 located on the testing tray 400 is tested using a testing device. The testing process and testing items are not limited.
[0079] After the inspection is completed, the third variable-pitch robot 130 is controlled to move the array of products 700 in the third position to the fourth position. During the moving process, the first target spacing X2 between multiple products 700 in the X direction is changed to the product spacing X1. The third variable-pitch robot 130 moves between the third and fourth positions to move the products 700 from the inspection tray 400 (X2, Y2) to the second buffer tray 500 (X1, Y2). During the moving process, the product spacing in the X direction is changed from X2 to X1. At this time, the products 700 are located in the second buffer tray 500 with a column spacing of X1 and a row spacing of Y2.
[0080] Subsequently, the fourth variable-pitch robot 140 transports the arrayed products 700 at the fourth position to the fifth position. During the transport process, the second target spacing Y2 between the multiple products 700 along the Y direction is changed to the product spacing Y1. The fourth variable-pitch robot 140 moves between the fourth and fifth positions to transport the products 700 from the second buffer tray 500 (X1, Y2) to the receiving tray 600 (X1, Y1). During the transport process, the product spacing in the Y direction is changed from Y2 to Y1. At this time, the products 700 are located in the receiving tray 600 with a column spacing of X1 and a row spacing of Y1.
[0081] The above-mentioned handling method uses multiple robotic arms to complete the pitch change in one direction to achieve complex pitch changes. The multiple robotic arms operate simultaneously without interfering with each other. The overall structure is simple, the movement distance of each pitch-changing robotic arm is shortened, and the handling efficiency is high.
[0082] In one embodiment, during the loading process of the loading robot, at least one interference detection device is controlled to detect the distance between the first variable-pitch robot 110 and the second variable-pitch robot 120 in real time. An alarm is triggered when the distance between the first variable-pitch robot 110 and the second variable-pitch robot 120 is lower than an alarm distance. It is understood that the alarm distance can be adjusted according to the size of each component and the moving speed of the variable-pitch robot during actual production. During the receiving process of the receiving robot, at least one interference detection device is controlled to detect the distance between the third variable-pitch robot 130 and the fourth variable-pitch robot 140 in real time, respectively. An alarm is triggered when the distance between the third variable-pitch robot 130 and the fourth variable-pitch robot 140 is lower than an alarm distance.
