[0037] The technical solutions provided by the embodiments of this application will be introduced below with reference to the accompanying drawings.
[0038] Refer to Figure 1 and Figure 2 As shown, this application provides a feeding device 100. The feeding device 100 includes a machine table (not shown in the figure), a conveyor belt 110 and a feeding module 120. The conveyor belt 110 and the feeding module 120 are both disposed on the machine table. The feeding device 100 is used for the feeding operation of products. Among them, in this embodiment, the product is a chip to be tested. Of course, in other feasible embodiments, the product can also be a camera, a circuit board, etc. The specific component type of the product is not limited in this application.
[0039] The material conveying belt 110 has a loading position 111 and a return position 112. The loading position 111 is for loading the full Tray trays 200, and the return position 112 is for unloading the empty Tray trays 300. The empty Tray trays 300 can move on the material conveying belt 110 from the loading position 111 towards the return position 112. The loading module 120 is used to feed the full Tray trays 200 to the loading position 111. Among them, the full Tray trays 200 carry products, and the empty Tray trays 300 do not carry products. Exemplarily, first, the loading module 120 feeds the full Tray trays 200 carrying products to the loading position 111; then, the unloading operation of the products is performed at the loading position 111. After the full Tray trays 200 are emptied of products, they are switched to empty Tray trays 300; finally, the empty Tray trays 300 move on the material conveying belt 110 from the loading position 111 towards the return position 112, and the unloading operation of the empty Tray trays 300 is performed at the return position 112.
[0040] For the above-mentioned loading device 100, the empty Tray trays 300 can be transferred to the return position 112 for the unloading operation. The empty Tray trays 300 do not need to perform the unloading operation at the loading position 111. Only by transferring the empty Tray trays 300 without carrying products to the return position 112, the loading position 111 can be made idle, and the loading operation of the full Tray trays 200 can be performed at the loading position 111. That is to say, the replacement and loading operation of the full Tray trays 200 does not need to wait for the unloading time of the empty Tray trays 300, which can reduce the replacement and loading time of the full Tray trays 200 and improve the loading efficiency of the products.
[0041] In one embodiment, referring to Figures 1 - 3 As shown, the loading module 120 includes a bin 121, a lifting assembly 122 and a pallet 123. For example, the bin 121 is a cavity structure formed by enclosing multiple side plates. The pallet 123 and the side wall of the bin 121 enclose a loading space 124 for carrying the full Tray trays 200. The pallet 123 is rotatably arranged in the bin 121. For example, the pallet 123 is rotatably connected to the bin 121 through a rotating pair such as a hinge or a hinge, and the pallet 123 has a first state of flipping to the outside of the bin 121 and a second state of flipping to the inside of the bin 121. Exemplarily, when the pallet 123 is in the first state, the pallet 123 can be flipped to the outside of the bin 121 for the loading operation of the full Tray trays 200. Another example is that when the pallet 123 is in the second state, the pallet 123 carrying the full Tray trays 200 can be flipped to the inside of the bin 121 for the loading operation of the full Tray trays 200. The lifting assembly 122 is arranged on the machine table. The lifting assembly 122 is used to feed the full Tray trays 200 in the loading space 124 to the loading position 111, so that the full Tray trays 200 can perform the loading operation of the products at the loading position 111.
[0042] Specifically, referring to Figures 1 - 3As shown, in order to improve the feeding efficiency of the product, multiple full Tray trays 200 are usually placed in the loading space 124 in a stacked manner for batch feeding. That is to say, there are multiple full Tray trays 200 in the loading space 124. The lifting assembly 122 includes a lifting module (not shown in the figure) and a tray separating module (not shown in the figure). The tray separating module can be inserted into the gap between two adjacent layers of full Tray trays 200, and the lifting module can lift the separated full Tray tray 200. Exemplarily, the tray separating module can be inserted between the topmost full Tray tray 200 and the adjacent full Tray tray 200, and the lifting module can lift the topmost full Tray tray 200; or, the tray separating module can be inserted between the bottommost full Tray tray 200 and the adjacent full Tray tray 200, and the lifting module can lift all the full Tray trays 200 except the bottommost full Tray tray 200.
[0043] In one implementation, the tray separating module can be inserted between the topmost full Tray tray 200 and the adjacent full Tray tray 200 to separate the topmost full Tray tray 200 from other full Tray trays 200. The lifting module can lift the topmost full Tray tray 200 and place the topmost full Tray tray 200 on the conveyor belt 110 by moving, so as to lift and feed the separated topmost full Tray tray 200 to the loading position 111, enabling the topmost full Tray tray 200 to perform the product feeding operation at the loading position 111.
[0044] In another implementation, the conveyor belt 110 is located below the magazine 121, and there are two conveyor belts 110. The distance between the two conveyor belts 110 is greater than the size of the tray 123 and less than the size of the full Tray tray 200, and the tray 123 can move towards or away from the conveyor belt 110. The tray separating module can be inserted between the bottommost full Tray tray 200 and the adjacent full Tray tray 200 to separate the bottommost full Tray tray 200 from other full Tray trays 200. The lifting module can lift all the full Tray trays 200 except the bottommost full Tray tray 200. At this time, only the bottommost full Tray tray 200 is carried on the tray 123. The tray 123 moves towards the conveyor belt 110. Since the distance between the two conveyor belts 110 is greater than the size of the tray 123 and less than the size of the full Tray tray 200, when the tray 123 drives the full Tray tray 200 to move to the position of the conveyor belt 110, the tray 123 will sink into the space between the two conveyor belts 110, and the full Tray tray 200 will overlap on the two conveyor belts 110. The full Tray tray 200 is fed to the loading position 111 by the conveyor belt 110 for the product feeding operation.
[0045] Of course, it should be noted that in other feasible embodiments, the tray separation module can also be inserted into the gap between two adjacent middle full Tray trays 200 to separate multiple layers of full Tray trays 200. The present application does not limit the position where the tray separation module is inserted and the number of layers of full Tray trays 200 separated at one time.
[0046] Further, referring to Figures 1 - 3 As shown, the loading module 120 further includes a connecting member 125, an anti-misalignment strip 126, and a locking member 127. The connecting member 125, the anti-misalignment strip 126, and the locking member 127 are all disposed in the magazine 121. In this embodiment, the bottom of the magazine 121 is in a hollow state. When the full Tray tray 200 is placed in the loading space 124, the full Tray tray 200 may only be supported by the pallet 123, which may cause the problem of the tray falling off. Based on this, when the full Tray tray 200 is placed in the loading space 124, the connecting member 125 can lift the bottom full Tray tray 200. For example, the connecting member 125 is in a plate-like structure. By the extension of the connecting member 125 in cooperation with the pallet 123, the stability of the full Tray tray 200 during loading and replacement is ensured. Since the full Tray tray 200 has a notch to indicate the direction of the full Tray tray 200, when the full Tray tray 200 is placed in the loading space 124, the anti-misalignment strip 126 cooperates with the notch of the full Tray tray 200 to ensure the accuracy of the placement position of the full Tray tray 200. Among them, if the placement position of the full Tray tray 200 is incorrect, the anti-misalignment strip 126 cannot cooperate with the full Tray tray 200, reminding the operator to correct the position of the full Tray tray 200 in time, effectively avoiding the misalignment of the full Tray tray 200 during loading. The locking member 127 is used to lock the pallet 123 in the second state, avoiding the problem that the full Tray tray 200 moves in the loading position due to the self-movement of the pallet 123 during loading.
[0047] In one embodiment, referring to Figures 1 - 3 As shown, the loading device 100 further includes a positioning module 130. The positioning module 130 is disposed on the machine table, and the positioning module 130 is located at the loading position 111. The positioning module 130 is used to position the full Tray tray 200 at the loading position 111. Exemplarily, when the loading module 120 loads the full Tray tray 200 to the loading position 111, the positioning module 130 positions the full Tray tray 200 at the loading position 111, avoiding the movement of the full Tray tray 200 at the loading position 111 and ensuring the accuracy of the loading position of the products carried in the full Tray tray 200.
[0048] Specifically, referring to Figures 1 - 3As shown, the positioning module 130 includes a support component 131 and a crimping component 132. When the full Tray tray 200 is carried at the loading position 111, the support component 131 abuts against the lower surface of the full Tray tray 200, and the crimping component 132 crimps against the lower surface of the full Tray tray 200. Through the mutual cooperation of the support component 131 and the crimping component 132, the clamping and fixing of both sides of the full Tray tray 200 are realized, so that the full Tray tray 200 is positioned at the loading position 111, ensuring the accuracy of the loading position of the products carried in the full Tray tray 200. Moreover, the support component 131 supports the full Tray tray 200 to prevent the full Tray tray 200 from deforming, and the crimping component 132 crimps against the upper surface of the full Tray tray 200 to ensure the flatness and stability of the full Tray tray 200 during the loading process, and improve the success rate of adsorption and picking of the products during the loading process.
[0049] Further, continue to refer to Figures 1 - 4 As shown, the support component 131 includes a first driving member 1311, a transmission member 1312, a support plate 1313 and a sensing member 1314. The sensing member 1314 is communicatively connected to the first driving member 1311. For example, the sensing member 1314 is communicatively connected to the first driving member 1311 by means of cables, WIFI, Bluetooth, etc. The sensing member 1314 is used to sense whether there is a full Tray tray 200 at the loading position 111. The support plate 1313 is connected to the first driving member 1311 through the transmission member 1312. For example, the transmission member 1312 is arranged at the output end of the first driving member 1311 and is connected to the support plate 1313. The support plate 1313 can abut against the lower surface of the full Tray tray 200. Exemplarily, when the full Tray tray 200 is placed at the loading position 111, the sensing member 1314 senses the existence of the full Tray tray 200 at the loading position 111, and the sensing member 1314 feeds back a signal to the first driving member 1311. The first driving member 1311 outputs power to the support plate 1313, driving the support plate 1313 to move towards the direction close to the lower surface of the full Tray tray 200, so that the support plate 1313 abuts against the lower surface of the full Tray tray 200, realizing the positioning and fixing of the full Tray tray 200. Among them, the first driving member 1311 can be a driving motor, a driving cylinder or other components capable of outputting power, the transmission member 1312 can be a lead screw module, a sliding module or other components capable of transmitting power, and the sensing member 1314 can be a photoelectric sensor, a position sensor or other components capable of obtaining the position state of the full Tray tray 200. The specific types of components for the first driving member 1311, the transmission member 1312 and the sensing member 1314 are not limited in this application.
[0050] The crimping assembly 132 includes a second driving member 1321 and a crimping plate 1322. The crimping plate 1322 is in transmission connection with the second driving member 1321, and the crimping plate 1322 can be crimped on the upper surface of the full Tray tray 200. Exemplarily, when the full Tray tray 200 is placed at the loading position 111, the second driving member 1321 outputs power to the crimping plate 1322, driving the crimping plate 1322 to move towards the direction close to the upper surface of the full Tray tray 200, so that the crimping plate 1322 is crimped on the upper surface of the full Tray tray 200. The crimping plate 1322 cooperates with the support plate 1313 to clamp and fix both sides of the full Tray tray 200, positioning the full Tray tray 200 at the loading position 111 and ensuring the accuracy of the loading position of the products carried in the full Tray tray 200. Among them, the second driving member 1321 is a driving motor, a driving cylinder or other components capable of outputting power. The specific type of the second driving member 1321 is not limited in this application.
[0051] In one embodiment, referring to Figure 1 and Figure 2 as shown, the feeding device 100 further includes a check module 140. The check module 140 is arranged on the machine table, and the check module 140 is located at the return position 112. The check module 140 is used to prevent the empty Tray tray 300 from moving from the return position 112 towards the loading position 111. Exemplarily, the check module 140 is a check cylinder. When the empty Tray tray 300 flows from the loading position 111 to the return position 112 and performs a blanking operation at the return position 112, the check module 140 acts to block the empty Tray tray 300 from moving from the return position 112 towards the loading position 111, so that the empty Tray tray 300 can perform a blanking operation at the blanking position.
[0052] In one embodiment, referring to Figure 1 and Figure 2 as shown, there are multiple feeding modules 120, and the multiple feeding modules 120 are arranged on the machine table at intervals. The multiple feeding modules 120 can alternately perform the feeding operation of the full Tray tray 200 to the loading position 111 and the replacement operation of the full Tray tray 200. For example, when one feeding module 120 is performing the feeding operation of the full Tray tray 200 to the loading position 111, other feeding modules 120 can perform the replacement operation of the full Tray tray 200, improving the feeding efficiency of the products. Among them, in this embodiment, as Figure 1 shown, there are two feeding modules 120, and the two feeding modules 120 are arranged on the machine table at intervals. Moreover, the multiple feeding modules 120 are all located at the side of the machine table, and the feeding modules 120 do not occupy the middle position of the machine table, reasonably arranging the installation positions of the feeding modules 120. Of course, in other feasible embodiments, the number of the feeding modules 120 can also be three, four or other numbers. The specific number of the feeding modules 120 is not limited in this application.
[0053] In addition, refer to Figure 1 and Figure 2 As shown, the present application also provides a test line body, which includes a loading device 100 as described in the above technical solution, and the test line body is used for the loading and testing operations of products.
[0054] For the above test line body, the empty Tray tray 300 can be transferred to the return position 112 for unloading operation. The replacement and loading operation of the full Tray tray 200 does not need to wait for the unloading time of the empty Tray tray 300, which can reduce the replacement and loading time of the full Tray tray 200 and improve the loading efficiency of products.
[0055] The following combines Figures 1 - 4 to describe in detail the loading action of the loading module 100 provided by the present application for products:
[0056] First, the empty Tray tray 300 is filled with products, and the empty Tray tray 300 is switched to the full Tray tray 200; then, the pallet 123 rotates to the first state located outside the magazine 121, and a plurality of full Tray trays 200 are stacked and loaded into the loading space 124. After a plurality of full Tray trays 200 are stacked on the pallet 123, the pallet 123 rotates in the reverse direction to the second state located inside the magazine 121; then, the tray separation module is inserted between the top full Tray tray 200 and the adjacent full Tray tray 200 to separate the top full Tray tray 200 from the other full Tray trays 200, and the lifting module lifts the top full Tray tray 200 to lift and feed the top full Tray tray 200 to the loading position 111; or, the tray separation module is inserted between the bottom full Tray tray 200 and the adjacent full Tray tray 200 to separate the bottom full Tray tray 200 from the other full Tray trays 200, and the lifting module lifts the other full Tray trays 200 except the bottom full Tray tray 200 to lift and feed the bottom full Tray tray 200 to the loading position 111; continue, perform the unloading operation of the products at the loading position 111, and switch to the empty Tray tray 300 after the full Tray tray 200 is emptied of products; finally, the empty Tray tray 300 moves from the loading position 111 to the return position 112 on the conveyor belt 110, and performs the unloading operation of the empty Tray tray 300 at the return position 112.
[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered to be within the scope described in this specification.
[0058] The above-described embodiments merely represent several implementation manners of the present application.
