Description

Technical Field

[0001] This application relates to the field of product loading and unloading technology, and in particular to a loading and unloading device and method. Background Technology

[0002] In automated production and testing processes, products typically involve loading and unloading. For example, when testing chips, the chips to be tested need to be loaded onto the test station for electrical bonding testing. After the chip testing is completed, the tested chips need to be unloaded to transfer them to the next process.

[0003] Currently, during the product loading and unloading process, a robotic arm simultaneously grasps multiple products and delivers them to testing stations for testing. However, when loading and unloading products at multiple testing stations, the robotic arm must move sequentially to each station to load the products in order, and after each product test is completed, the robotic arm must move sequentially to each station to unload the products in order. Since loading and unloading products at each testing station takes time—meaning the product must wait for the previous testing station to complete its loading and unloading process before it can proceed to the next—this results in a significant time commitment for loading and unloading at each testing station, severely impacting the overall efficiency of product loading and unloading. Summary of the Invention

[0004] Therefore, it is necessary to provide a loading and unloading device and method to address the problem of low loading and unloading efficiency in existing products.

[0005] A loading and unloading device, the loading and unloading device comprising:

[0006] Machine tool;

[0007] The feeding rail is provided on the machine base and has a loading position and a unloading position, and has a plurality of test positions spaced apart along the extension direction of the feeding rail;

[0008] The feeding module includes multiple feeding shafts corresponding to multiple test positions. Each feeding shaft has a first bearing cavity for carrying the product. The multiple feeding shafts are slidably disposed on the feeding rail and can reciprocate between the feeding position and the corresponding test position.

[0009] The unloading module includes multiple unloading shafts corresponding to multiple test positions. Each unloading shaft has a second bearing cavity for carrying the product. The multiple unloading shafts are slidably disposed on the feeding rail and can reciprocate between the unloading position and the corresponding test position.

[0010] In one embodiment, the feeding module has a first retracted state and a first extended state. When the feeding module is in the first retracted state, multiple feeding shafts are arranged side by side at the feeding position. When the feeding module is in the first extended state, multiple feeding shafts move to multiple test positions accordingly.

[0011] The feeding module has a second retracted state and a second extended state. When the feeding module is in the second retracted state, multiple feeding shafts are arranged side by side at the feeding position. When the feeding module is in the second extended state, multiple feeding shafts move to multiple test positions.

[0012] In one embodiment, during the product loading process, multiple loading shafts can move synchronously to the loading position, and multiple loading shafts can move synchronously to the corresponding test position;

[0013] During the product unloading process, multiple unloading shafts can move synchronously to the unloading position, and multiple unloading shafts can move synchronously to the corresponding test position.

[0014] In one embodiment, the machine has a picking position and a discharging position, the picking position is stacked with the product to be tested, and the discharging position is for discharging the product after testing;

[0015] The loading and unloading device further includes a material picking module and a material discharging module, both of which are mounted on the machine base. The material picking module includes a first driving component and a plurality of first adsorption modules that are pulsatorically connected to the first driving component. The plurality of first adsorption modules can move between the material picking position and the material loading position. The material discharging module includes a plurality of second adsorption modules that can move between the material unloading position and the material discharging position.

[0016] In one embodiment, the feeding module further includes a plurality of second driving components corresponding to a plurality of second adsorption modules, wherein the second driving components are drively connected to the corresponding second adsorption modules.

[0017] In one embodiment, the loading and unloading device further includes a tray-retrieving module, which is movably disposed on the machine and can move to the unloading position. The tray-retrieving module is used to feed an empty tray to the unloading position for unloading the product.

[0018] In one embodiment, the tray retrieval module includes a fixed frame and a camera module, a third driving component, and a suction cup, all mounted on the fixed frame. The fixed frame is movably mounted on the machine platform. The camera module is used for positioning the empty tray. The suction cup is connected to the third driving component for adsorbing the empty tray.

[0019] In one embodiment, the loading and unloading device further includes a positioning module, which is disposed on the machine and located at the loading position. The positioning module is used to determine whether the first bearing cavity of the multiple loading shafts carries the product and to obtain the position information of the multiple loading shafts.

[0020] In one embodiment, the loading and unloading device further includes a position adjustment module, which is disposed on the machine base and is used to adjust the relative position of the machine base and the feeding rail.

[0021] A loading / unloading method for a loading / unloading device as described in any of the above technical solutions, the loading / unloading method comprising the following steps:

[0022] All of the feeding shafts move to the feeding position and perform the product feeding operation at the feeding position;

[0023] Once the first bearing cavity of each of the multiple feeding shafts is filled with the product, the multiple feeding shafts move to the corresponding test position and send the product to the corresponding test position for testing.

[0024] Multiple feeding shafts move to the feeding position, and multiple unloading shafts move to the corresponding testing position to carry the tested product.

[0025] Once the second bearing cavity of each of the multiple feeding shafts is filled with the tested product, the multiple feeding shafts move to the feeding position to perform the feeding operation.

[0026] The aforementioned loading and unloading device and method firstly involves multiple loading shafts moving to the loading position and loading products there. Then, once the first bearing chambers of the multiple loading shafts are filled with products, the shafts move to their corresponding testing positions, sequentially delivering the products for testing. Next, the loading shafts move to the loading position, and the unloading shafts move to their corresponding testing positions to load the tested products. Finally, once the second bearing chambers of the multiple unloading shafts are filled with tested products, the shafts move to their unloading positions to unload the products. The loading and unloading device provided in this application, through the reciprocating motion of multiple loading shafts between the loading position and the corresponding testing position, and the reciprocating motion of multiple unloading shafts between the unloading position and the corresponding testing position, can simultaneously achieve automatic batch loading and unloading of products at multiple testing positions. Furthermore, by alternating the movement of the loading module and the unloading module at the testing positions, the loading, unloading, and testing time can be shortened, improving the efficiency of product loading, unloading, and testing.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0045] See Figures 1-4 As shown, this application provides a loading / unloading device 100, which includes a machine base 110, a feeding rail 120, a loading module 130, and an unloading module 140. The loading / unloading device 100 is used for loading and unloading products. In this embodiment, the product is a chip under test. Of course, in other feasible embodiments, the product can also be a camera, a circuit board, etc. This application does not limit the specific component type of the product.

[0046] A feeding rail 120 is disposed on the machine base 110, and the feeding rail 120 has a loading position 121 and a unloading position 122, and has a plurality of test positions 123 spaced apart along the extending direction of the feeding rail 120. For example, see [reference needed]. Figure 3 and Figure 4As shown, the loading position 121 is located at one end of the feeding rail 120, where product loading operations can be performed. The unloading position 122 is located at the other end of the feeding rail 120, where product unloading operations can be performed. There are multiple test positions 123, which are distributed at intervals along the extension direction of the feeding rail 120, where product testing operations can be performed.

[0047] The feeding module 130 includes multiple feeding shafts 131, which correspond to multiple test positions 123. Each feeding shaft 131 has a first bearing cavity 1311 for carrying the product to be tested. The multiple feeding shafts 131 are slidably disposed on the feeding rail 120, and can reciprocate between the feeding position 121 and the corresponding test position 123. For example, the number of feeding shafts 131 and test positions 123 is the same, and each feeding shaft 131 corresponds to each test position 123. For example, there are five feeding shafts 131 and five test positions 123, and the five test positions 123 are spaced apart along the extension direction of the feeding rail 120. The multiple feeding shafts 131 can realize batch feeding of five products to five test positions 123 at a time. For example, the number of test positions 123 is twice that of the feeding shaft 131. The feeding shaft 131 has two first bearing cavities 1311 at both ends, and one feeding shaft 131 corresponds to two test positions 123. If there are five feeding shafts 131, there are ten test positions 123. The ten test positions 123 are arranged at intervals along the extension direction of the feeding rail 120. The ten test positions 123 are symmetrically arranged on both sides of the feeding rail 120. Multiple feeding shafts 131 can realize batch feeding of ten products at ten test positions 123 at a time.

[0048] The unloading module 140 includes multiple unloading shafts 141, which correspond to multiple test positions 123. Each unloading shaft 141 has a second bearing cavity 1411 for carrying the tested product. The multiple unloading shafts 141 are slidably disposed on the feeding rail 120, and can reciprocate between the unloading position 122 and the corresponding test position 123. For example, the number of unloading shafts 141 and test positions 123 is the same, and each unloading shaft 141 corresponds to each test position 123. For example, there are five unloading shafts 141 and five test positions 123, and the five test positions 123 are spaced apart along the extension direction of the feeding rail 120. The multiple unloading shafts 141 can unload five products at five test positions 123 at a time. For example, the number of test positions 123 is twice that of the feeding shaft 141. The feeding shaft 141 has two second bearing cavities 1411 at both ends, and one feeding shaft 141 corresponds to two test positions 123. If there are five feeding shafts 141, there are ten test positions 123. The ten test positions 123 are arranged at intervals along the extension direction of the feeding rail 120. The ten test positions 123 are symmetrically arranged on both sides of the feeding rail 120. The multiple feeding shafts 141 can realize the batch feeding of ten products at ten test positions 123 at a time.

[0049] When the loading / unloading device 100 needs to perform loading / unloading and testing operations on products, firstly, multiple loading shafts 131 move to the loading position 121 and load products at the loading position 121; then, after the first bearing cavity 1311 of the multiple loading shafts 131 is loaded with products, the multiple loading shafts 131 move to the corresponding testing position 123 and send the products to the corresponding testing position 123 for testing in sequence; next, the multiple loading shafts 131 move to the loading position 121, and the multiple unloading shafts 141 move to the corresponding testing position 123 to load the tested products; finally, after the second bearing cavity 1411 of the multiple unloading shafts 141 is loaded with the tested products, the multiple unloading shafts 141 move to the unloading position 122 to unload products. Through the reciprocating motion of multiple feeding shafts 131 between the feeding position 121 and the corresponding test position 123, and the reciprocating motion of multiple unloading shafts 141 between the unloading position 122 and the corresponding test position 123, the loading and unloading operations of each test position 123 are completed synchronously. This enables the batch automatic loading and unloading of products at multiple test positions 123 simultaneously. Furthermore, through the alternating movement of the feeding module 130 and the unloading module 140 at the test position 123, the product loading and unloading operations are independent of each other. For example, when the feeding module 130 sends the product to be tested to the test position 123 for testing, while the feeding module 130 returns to the feeding position 121 to load the product, the unloading module 140 can move towards the test position 123 to unload the product. This can shorten the product loading and unloading and testing time and improve the product loading and unloading and testing efficiency.

[0050] In one embodiment, see Figures 1-4 As shown, the feeding module 130 has a first retracted state and a first extended state. When the feeding module 130 is in the first retracted state, multiple feeding shafts 131 are arranged side by side at the feeding position 121. When the feeding module 130 is in the first extended state, the multiple feeding shafts 131 move to multiple testing positions 123. For example, see [reference needed]. Figure 3 As shown, when the feeding module 130 is in the first retracted state, multiple feeding shafts 131 are arranged side by side at the feeding position 121 to perform product feeding operations. After each of the multiple feeding shafts 131 has a product in its first bearing cavity 1311, the multiple feeding shafts 131 move along... Figure 3 As shown, the loading module 130 moves from the first retracted state to the first extended state, and each loading shaft 131 moves to its corresponding test position 123 to deliver the product carried by each loading shaft 131 to the corresponding test position 123 for testing. After the loading operation is completed, multiple loading shafts 131 move along... Figure 3As shown, the feeding module 130 moves from a first extended state to a first retracted state, and multiple feeding shafts 131 move to the feeding position 121 for another feeding operation. The unloading module 140 has a second retracted state and a second extended state. When the unloading module 140 is in the second retracted state, multiple unloading shafts 141 are located side by side at the unloading position 122. When the unloading module 140 is in the second extended state, multiple unloading shafts 141 move to multiple test positions 123 respectively. For example, see [reference needed]. Figure 4 As shown, after the feeding module 130 completes feeding at test position 123 and leaves test position 123, the unloading module 140 moves along... Figure 4 As shown, the material feeding module 140 moves in the direction from C to D, switching from the second retracted state to the second extended state. Each feeding shaft 141 moves to its corresponding test position 123 to carry the tested product. After each feeding shaft 141 has a product in its second bearing cavity 1411, the multiple feeding shafts 141 move along... Figure 4 As shown, the material feeding module 140 moves from the second extended state to the second retracted state as it moves in the direction from D to C. Multiple feeding shafts 141 move to the feeding position 122 to perform the product feeding operation.

[0051] It should be noted that when the feeding module 130 switches from the first extended state to the first retracted state, the unloading module 140 can simultaneously switch from the second retracted state to the second extended state, so as to save product loading and unloading time and improve product loading and unloading efficiency.

[0052] Further reading Figure 3 and Figure 4As shown, during the product loading process, multiple loading shafts 131 can move synchronously to the loading position 121, and can also move synchronously to the corresponding testing position 123. Since the testing positions 123 are spaced apart along the extension direction of the feeding rail 120, the distances from each loading shaft 131 to its corresponding testing position 123 will differ. By controlling the movement speed of each loading shaft 131 through differential speed control, each loading shaft 131 moves synchronously between the loading position 121 and the testing position 123. Each loading shaft 131 simultaneously performs loading operations at the loading position 121 and simultaneously delivers the product to the testing position 123 for testing. There is no waiting time for each loading shaft 131, which improves product loading efficiency. Similarly, during the product unloading process, multiple unloading shafts 141 can move synchronously to the unloading position 122, and can also move synchronously to the corresponding testing position 123. Since the test positions 123 are spaced apart along the extension direction of the feeding rail 120, the distance from each unloading shaft 141 to the corresponding test position 123 will be different. By controlling the movement speed of each unloading shaft 141 through differential speed control, each unloading shaft 141 moves synchronously between the unloading position 122 and the test position 123. Each unloading shaft 141 moves to each test position 123 at the same time to carry the product, and at the same time performs the unloading operation at the unloading position 122. There is no waiting time for each unloading shaft 141, which can improve the unloading efficiency of the product.

[0053] In one embodiment, see Figure 1 and Figure 2 As shown, the machine 110 has a pick-up position 111 and a discharge position 112. The pick-up position 111 is stacked with products to be tested. If the pick-up position 111 is filled with a tray, the tray contains the products to be tested. The discharge position 112 is used to discharge the products after testing. If the discharge position 112 is filled with an empty tray, the tray is used to discharge the products after testing.

[0054] Continue reading Figures 3-6 As shown, the loading and unloading device 100 also includes a picking module 150 and a discharging module 160, both of which are mounted on the machine base 110. The picking module 150 includes a first driving component 151 and multiple first adsorption modules 152. The first driving component 151 and the multiple first adsorption modules 152 are fixed to the machine base 110 via a first mounting bracket 153. The multiple first adsorption modules 152 can move between the picking position 111 and the loading position 121 to load the products to be tested stacked at the picking position 111 onto the loading shaft 131 for loading operations. The discharging module 160 includes multiple second adsorption modules 161, which can move between the unloading position 122 and the discharging position 112 to unload the tested products that have moved to the unloading position 122.

[0055] Typically, during the product unloading process after testing, multiple second adsorption modules move as a whole to adsorb the tested product. This results in inflexible unloading and makes product sorting impossible. Therefore, in one embodiment, see... Figure 6 As shown, the feeding module 160 also includes multiple second driving components 162 and a second mounting bracket 163. The second driving components 162 and multiple second adsorption modules 161 are all fixed to the machine base 110 via the second mounting bracket 163. Each second driving component 162 corresponds to a second adsorption module 161, meaning each second adsorption module 161 is independently equipped with a second driving component 162. The second driving component 162 is connected to the corresponding second adsorption module 161 via a transmission connection. Power is output from the second driving component 162, which drives the second adsorption module 161 to independently adsorb and feed the product into the corresponding second bearing cavity 1411. Thus, the second adsorption module 161 independently adsorbs and feeds the product into the feeding module 140 located at the feeding position 122, adapting to the positions of products in different second bearing cavities 1411. Furthermore, since there may be defective products after testing, the second adsorption module 161 can independently adsorb products, enabling the sorting of qualified and defective products. For example, when there are defective products among the tested products, some of the second adsorption modules 161 adsorb qualified products and send them to the OK line for unloading, while some of the second adsorption modules 161 adsorb defective products and send them to the NG line for unloading, so as to sort and unload the tested products into OK / NG categories.

[0056] Preferably, multiple first adsorption modules 152 are detachably connected to the first mounting frame 153 via magnetic attraction, snap-fit, or other detachable methods, facilitating the disassembly and maintenance of the first adsorption modules 152. Furthermore, when the specifications of the product to be adsorbed change, different specifications of the first adsorption modules 152 can be replaced to adapt to the adsorption of products of different specifications, improving the applicability of adsorbable product specifications. Similarly, multiple second adsorption modules 161 are detachably connected to the second mounting frame 163 via magnetic attraction, snap-fit, or other detachable methods, facilitating the disassembly and maintenance of the second adsorption modules 161. Furthermore, when the specifications of the product to be adsorbed change after testing, different specifications of the second adsorption modules 161 can be replaced to adapt to the adsorption of products of different specifications after testing, improving the applicability of adsorbable product specifications after testing. And, see also... Figure 1As shown, there are two feeding modules 160, which are spaced apart on both sides of the machine base 110. The two feeding modules 160 can alternately absorb and feed the product, improving the feeding efficiency. In this embodiment, the first driving component 151 and the second driving component 162 can be any one of a drive motor or a blade battery. In other feasible embodiments, the first driving component 151 and the second driving component 162 can also be a drive cylinder or other components capable of outputting power. This application does not limit the specific component types of the first driving component 151 and the second driving component 162.

[0057] Further, see Figure 1 , Figure 2 and Figure 7 As shown, the loading and unloading device 100 also includes a tray-grabbing module 170, which is movably mounted on the machine base 110 and can move to the unloading position 112. The tray-grabbing module 170 is used to feed empty trays to the unloading position 112 for product unloading. Preferably, there are two tray-grabbing modules 170, and the two modules 150 are spaced apart on both sides of the machine base 110. The two tray-grabbing modules 170 can alternately grab and feed empty trays, improving the product unloading efficiency.

[0058] Further, see Figure 7 As shown, the tray retrieval module 170 includes a mounting frame 171, a camera module 172, a third drive component 173, and a suction cup 174. The mounting frame 171 is movably mounted on the machine base 110. The camera module 172, the third drive component 173, and the suction cup 174 are all mounted on the mounting frame 171, so that the tray retrieval module 170 can be installed and fixed on the machine base 110 through the mounting frame 171. The camera module 172 is used for positioning empty trays, and the suction cup 174 is connected to the third drive component 173 for adsorption of empty trays. For example, when an empty tray needs to be fed to the unloading position 112, the camera module 172 acquires the position of the empty tray and feeds the position information of the empty tray back to the control module. The control module controls the movement of the fixing frame 171 relative to the machine platform 110 so that the suction cup 174 moves to a position where it can pick up the empty tray. The third drive unit 173 outputs power so that the suction cup 174 moves toward the empty tray and picks up the empty tray. The control module controls the fixing frame 171 to move relative to the machine platform 110 to the unloading position 112 so as to feed the empty tray to the unloading position 112 for product unloading.

[0059] In this embodiment, the third driving component 173 is a driving cylinder. In other feasible embodiments, the third driving component 173 may also be a driving motor or other components capable of outputting power. This application does not limit the specific component type of the third driving component 173.

[0060] In one embodiment, see Figure 1 and Figure 2 As shown, the loading and unloading device 100 also includes a positioning module 180, which is disposed on the machine base 110 and located at the loading position 121. The positioning module 180 is used to determine whether the first bearing cavity 1311 of the multiple loading shafts 131 carries a product, so as to ensure that the loading shafts 131 can sequentially feed the product to be tested to the test position 123 for testing, and prevent the loading shafts 131 from being carried empty. In addition, the positioning module 180 can also obtain the position information of the multiple loading shafts 131 to ensure the accuracy of the product loading position in the first bearing cavity 1311. In this embodiment, the positioning module 180 can be a camera, photoelectric sensor or other components that can sense the product and its position. This application does not limit the specific component type of the positioning module 180.

[0061] In one embodiment, see Figure 1 and Figure 2 As shown, the loading and unloading device 100 also includes a position adjustment module 190. The position adjustment module 190 is disposed on the machine base 110 and is used to adjust the relative position of the machine base 110 and the feeding rail 120 to ensure the relative positional accuracy between the components disposed on the machine base 110 (such as the material picking module 150, the material unloading module 160, the tray picking module 170, the positioning module 180, etc.) and the feeding rail 120. Exemplarily, in this embodiment, refer to... Figure 1 and Figure 2 As shown, the machine base 110 includes a first frame 113 and a second frame 114, which are located at opposite ends of the feeding rail 120. Both the first frame 113 and the second frame 114 are equipped with a position adjustment module 190. The position adjustment module 190 includes a connecting block 191 and an adjusting component 192. The connecting block 191 is fixed to the worktable surface and is connected to the first frame 113 or the second frame 114 through the adjusting component 192. The adjusting component 192 can be any one of a bolt or a set screw. When there is a deviation in the relative position between the machine tool 110 and the feeding rail 120, the connection position between the connecting block 191 and the first frame 113 or the second frame 114 can be adjusted by adjusting the adjusting part 192. Since the connecting block 191 is fixed to the worktable, the first frame 113 and the second frame 114 can move, deflect or perform other actions relative to the worktable to adjust the relative position between the machine tool 110 and the feeding rail 120, so as to ensure the relative position accuracy between the fixed components of the machine tool 110 and the feeding rail 120.

[0062] In addition, please continue to refer to Figure 8 As shown, this application also provides a loading / unloading method for the loading / unloading device 100 as described in any of the above technical solutions, the loading / unloading method comprising the following steps:

[0063] Step S101: All multiple feeding shafts 131 move to the feeding position 121 and perform product feeding operations at the feeding position 121. For example, when the multiple feeding shafts 131 move to the feeding position 121, the picking module 150 sequentially places the product to be tested that it has adsorbed into the first bearing cavity 1311 of the multiple feeding shafts 131, so as to realize the feeding operation of the multiple feeding shafts 131 at the feeding position 121.

[0064] Step S102: After all the first bearing cavities 1311 of the multiple feeding shafts 131 are filled with products, the multiple feeding shafts 131 move to the corresponding test positions 123 and deliver the products to the corresponding test positions 123 for testing. For example, after all the first bearing cavities 1311 of the multiple feeding shafts 131 are filled with products, the multiple feeding shafts 131 move along... Figure 3 As shown, the loading module 130 moves from the first retracted state to the first extended state, and each loading shaft 131 moves to the corresponding test position 123 to deliver the product carried by each loading shaft 131 to the corresponding test position 123 for testing.

[0065] Step S103: Multiple feeding shafts 131 move to the feeding position 121, and multiple unloading shafts 141 move to the corresponding testing position 123 to perform a loading operation on the tested product. For example, after the feeding operation is completed, the multiple feeding shafts 131 move along... Figure 3 As shown, the loading module 130 moves from the first extended state to the first retracted state as it moves in the direction from B to A. Multiple loading shafts 131 move to the loading position 121 for another loading operation. Simultaneously, multiple unloading shafts 141 move along... Figure 4 As shown, the unloading module 140 moves from the second retracted state to the second extended state in the direction from C to D. Each unloading shaft 141 moves to its corresponding test position 123 to carry the tested product. When the loading module 130 switches from the first extended state to the first retracted state, the unloading module 140 can simultaneously switch from the second retracted state to the second extended state, saving product loading and unloading time and improving efficiency.

[0066] Step S104: After all the products tested have been loaded into the second bearing cavities 1411 of the multiple feeding shafts 141, the multiple feeding shafts 141 move to the unloading position 122 to perform the unloading operation. For example, after all the products have been loaded into the second bearing cavities 1411 of each feeding shaft 141, the multiple feeding shafts 141 move along... Figure 4As shown, the material feeding module 140 moves from the second extended state to the second retracted state as it moves in the direction from D to C. Multiple feeding shafts 141 move to the feeding position 122 to perform the product feeding operation.

[0067] The above-described loading and unloading method, through the reciprocating motion of multiple loading shafts 131 between loading position 121 and corresponding test position 123, and the reciprocating motion of multiple unloading shafts 141 between unloading position 122 and corresponding test position 123, can realize the automatic batch loading and unloading of products at multiple test positions 123. Furthermore, through the alternating motion of the loading module 130 and the unloading module 140 at the test position 123, the loading and unloading operations of the products are independent of each other. For example, when the loading module 130 sends the product to be tested to the test position 123 for testing, while the loading module 130 returns to the loading position 121 to load the product, the unloading module 140 can move towards the test position 123 to unload the product, which can shorten the loading and unloading time and testing time of the products and improve the loading and unloading efficiency and testing efficiency of the products.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
