[0037] The following introduces the technical solutions provided by the embodiments of the present application in conjunction with the accompanying drawings.
[0038] Refer to Figures 1-3 As shown, the present application provides a blanking device 100. The blanking device 100 includes a blanking module 110 and a carrier plate 120. The blanking device 100 is used for the blanking operation of products. Among them, the product is a test chip. 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 carrier plate 120 is movably disposed on the blanking module 110 through an adjusting member 130. The adjusting member 130 is used to adjust the gap size between the carrier plate 120 and the blanking module 110. The carrier plate 120 is used to carry an empty Tray tray (not shown in the figure). The empty Tray tray has a plurality of carrying cavities (not shown in the figure). The carrying cavities can be used for placing and carrying products. After products are blanked into multiple carrying cavities of the empty Tray tray, it is switched to a full Tray tray (not shown in the figure).
[0040] Traditionally, after the empty Tray tray is placed on the carrier plate, due to factors such as Tray tray specification changes or operation errors, the empty Tray tray may be inclined on the carrier plate, resulting in problems such as product edge touching and material jamming when the product is blanked into the carrying cavity of the empty Tray tray. The blanking device 100 provided by the present application can adjust the gap size between the carrier plate 120 and the blanking module 110 through the adjusting member 130, so as to adjust the carrier plate 120 to a position relative to the blanking module 110 that is horizontal, ensuring the levelness of the carrier plate 120 relative to the blanking module 110. Furthermore, the empty Tray tray carried on the carrier plate 120 is horizontal relative to the blanking module 110. When the blanking operation is performed on the product, the product can be horizontally placed in the carrying cavity of the empty Tray tray, and there will be no adverse phenomena such as product edge touching and material jamming, ensuring the accuracy of the blanking position of the product.
[0041] In one embodiment, refer to Figures 1-3As shown in the figure, the blanking module 110 includes a fixing frame 111 and a driving module 112. The fixing frame 111 is connected to the output end of the driving module 112, and the bearing plate 120 is movably arranged on the fixing frame 111 through an adjusting member 130. The bearing plate 120 is provided with a first through hole 121, and the fixing frame 111 is provided with a second through hole 1111 corresponding to and communicating with the first through hole 121. A part of the adjusting member 130 is accommodated in the first through hole 121, and another part of the adjusting member 130 is accommodated in the second through hole 1111. Preferably, the first through hole 121 is integrally formed on the bearing plate 120 by means of casting, extrusion, etc., and the second through hole 1111 is also integrally formed on the fixing frame 111 by means of casting, extrusion, etc., so as to simplify the forming process of opening the first through hole 121 on the bearing plate 120 and opening the second through hole 1111 on the fixing frame 111. Exemplarily, the adjusting member 130 is one of a set screw and a bolt. A part of the adjusting member 130 is accommodated in the first through hole 121, and another part of the adjusting member 130 is screwed into the second through hole 1111. By screwing the adjusting member 130, the screwing depth of the adjusting member 130 and the second through hole 1111 is changed, so as to adjust the gap size between the bearing plate 120 and the blanking module 110, and the bearing plate 120 is adjusted to a position horizontal relative to the fixing frame 111.
[0042] For the above-mentioned blanking device 100, when performing the blanking operation on the product, first, load the empty Tray tray onto the bearing plate 120, and adjust the gap size between the bearing plate 120 and the fixing frame 111 through the adjusting member 130 to adjust the bearing plate 120 to a position horizontal relative to the fixing frame 111; then, sequentially blank a plurality of products into a plurality of bearing cavities of the empty Tray tray, and switch to a full Tray tray after products are loaded into all the bearing cavities of the empty Tray tray; finally, the driving module 112 drives the fixing frame 111 to move, and the fixing frame 111 drives the full Tray tray to move to the product blanking position to perform the blanking operation on the products carried on the full Tray tray.
[0043] Further, referring to Figures 1-3 As shown in the figure, there are a plurality of adjusting members 130, and the plurality of adjusting members 130 are arranged at intervals along the circumferential direction of the bearing plate 120. Exemplarily, if there are four adjusting members 130 and the bearing plate 120 is a rectangular plate, the four adjusting members 130 are arranged at intervals at the four diagonal corners of the bearing plate 120. The gap between the bearing plate 120 and the blanking module 110 can be locally adjusted by one or several of the adjusting members 130. The plurality of adjusting members 130 can improve the adjustment flexibility of the gap between the bearing plate 120 and the blanking module 110 to accurately adjust the levelness of the bearing plate 120 relative to the blanking module 110.
[0044] It should be noted that the number of the adjusting members 130 can be two, three, five or other numbers, and the specific number of the adjusting members 130 is not limited in this application.
[0045] In one embodiment, referring to Figure 1 as shown, the blanking device 100 further includes a machine table 140 and a material taking module 150. The material taking module 150 is arranged on the machine table 140 by means of welding, screwing, etc., and the material taking module 150 faces the carrier plate 120. The material taking module 150 is used to receive the full Tray trays. Among them, after products are blanked into multiple loading cavities of an empty Tray tray, it is switched to a full Tray tray. Exemplarily, when products are blanked into multiple loading cavities of an empty Tray tray and it is switched to a full Tray tray, the full Tray tray can be transported to the material taking module 150 by the driving module 112 for storage, facilitating the subsequent blanking of the products carried by the full Tray tray.
[0046] Specifically, referring to Figure 1 as shown, the material taking module 150 includes a bin 151 and a pallet 152. For example, the bin 151 is a cavity-type structure surrounded by multiple side plates. The pallet 152 and the side wall of the bin 151 enclose a loading space 153 for the full Tray tray. The pallet 152 is movably arranged in the bin 151, and the pallet 152 has a first state of being pulled out to the outside of the bin 151 and a second state of being pushed into the inside of the bin 151. Exemplarily, when the pallet 152 is in the first state, the pallet 152 can be pulled out to the outside of the bin 151 for the blanking operation of the products carried by the full Tray tray. Also, when the pallet 152 is in the second state, the pallet 152 can be pushed into the inside of the bin 151 for the loading operation of the full Tray tray.
[0047] Furthermore, referring to Figure 1 , Figure 4 and Figure 5 as shown, the material taking module 150 further includes at least two slide rails 154 connected in sequence. The pallet 152 is slidably arranged in the bin 151 through multiple slide rails 154. By extending the multiple slide rails 154, the pallet 152 can be stretched to the outside of the bin 151, that is, the pallet 152 is in the first state, extending the stretching path of the pallet 152 and ensuring the stability of the pallet 152 during the sliding and stretching process. On the contrary, by retracting the multiple slide rails 154, the pallet 152 can be pushed into the inside of the bin 151, that is, the pallet 152 is in the second state, for the loading operation of the full Tray tray. Exemplarily, in this embodiment, there are two slide rails 154. The two slide rails 154 are respectively defined as the first slide rail 1541 and the second slide rail 1542. The first slide rail 1541 is arranged on the machine table 140, the second slide rail 1542 is slidably arranged on the first slide rail 1541, and the pallet 152 is arranged on the second slide rail 1542. Referring to Figure 4As shown, when the second slide rail 1542 moves relative to the first slide rail 1541 and extends to the outside of the first slide rail 1541, the second slide rail 1542 can drive the pallet 152 to move to the outside of the magazine 151. The stretching length of the magazine 151 is the total length of the first slide rail 1541 and the second slide rail 1542, which can increase the stretching path of the pallet 152 and ensure the stability of the pallet 152 during the sliding stretching process. Conversely, referring to Figure 5 As shown, when the second slide rail 1542 moves relative to the first slide rail 1541 and retracts to coincide with the first slide rail 1541, the second slide rail 1542 can drive the pallet 152 to move to the inside of the magazine 151, and the pallet 152 can move to the second state to perform the loading operation of the full Tray tray.
[0048] It should be noted that in other feasible embodiments, the number of the slide rails 154 can also be three, four or other numbers. The specific number of the slide rails 154 is not limited in this application, but the stability of the pallet 152 during the movement needs to be ensured during the setting of the slide rails 154.
[0049] In one embodiment, referring to Figure 1 and Figure 6 As shown, the picking module 150 further includes a limiting component 155 and an induction module 156. The limiting component 155 and the induction module 156 are both arranged on the machine table 140. The induction module 156 is communicatively connected to the limiting component 155. For example, the induction module 156 is communicatively connected to the limiting component 155 in forms such as cables, Bluetooth, and WIFI. The induction module 156 is used to sense the position of the pallet 152, and the limiting component 155 is used to lock the pallet 152 in the first state and the second state. Exemplarily, when the pallet 152 is pulled out to the outside of the magazine 151 and is in the first state, the induction module 156 senses the position of the pallet 152 and feeds back the position information of the pallet 152 in the first state to the limiting component 155. The limiting component 155 acts to lock the pallet 152 in the first state to perform the unloading operation of loading products on the full Tray tray; when the pallet 152 is pushed into the inside of the magazine 151 and is in the second state, the induction module 156 senses the position of the pallet 152 and feeds back the position information of the pallet 152 in the second state to the limiting component 155. The limiting component 155 acts to lock the pallet 152 in the second state to perform the loading operation of the full Tray tray.
[0050] Among them, in this embodiment, the induction module 156 can be a photoelectric sensor, a position sensor or other components capable of acquiring the position of the pallet 152. The specific component type of the induction module 156 is not limited in this application.
[0051] Specifically, continue to refer to Figure 7As shown, the support plate 152 has a stopper 1521. The limiting assembly 155 includes a limiting cylinder 1551, a first limiting member 1552 and a second limiting member 1553. The first limiting member 1552 and the second limiting member 1553 are arranged at intervals on the machine 140, such as the first limiting member 1552 is arranged on one side of the machine 140, and the second limiting member 1553 is arranged on the other side of the machine 140. The limiting cylinder 1551 is in transmission connection with the first limiting member 1552. When the support plate 152 is in the first state, the first limiting member 1552 cooperates with the stopper 1521, and when the support plate 152 is in the second state, the second limiting member 1553 cooperates with the stopper 1521. Exemplarily, as in the present embodiment, the locking member 1521, the first limiting member 1552 and the second limiting member 1553 are all magnetic members. When the tray 152 is in the first state, the limiting cylinder 1551 is actuated to drive the first limiting member 1552 to magnetically cooperate with the locking member 1521, so as to lock the tray 152 in the first state for unloading operations of a full tray carrying products; on the contrary, when the tray 152 is in the second state, the second limiting member 1553 to magnetically cooperate with the locking member 1521, so as to lock the tray 152 in the second state for loading operations of a full tray.
[0052] Among them, the cooperation method of the first limit member 1552, the second limit member 1553 and the locking member 1521 is not limited to the magnetic suction cooperation provided above, and can also be other elements that can lock the support plate 152, such as snap-on cooperation and plug-in cooperation. The present application does not impose any restrictions on the specific element types of the first limit member 1552, the second limit member 1553 and the locking member 1521.
[0053] Further, see Figure 1 and Figure 6 As shown, the material taking module 150 further includes a buffer 157. When the support plate 152 is in the first state, the buffer 157 abuts against the support plate 152 to buffer the force applied during the pulling process of the support plate 152, protect the support plate 152, and prevent the support plate 152 from being separated from the silo 151 due to excessive pulling force applied to the support plate 152. In this embodiment, the buffer 157 may be a silicone member, a plastic member, an elastic member, or other flexible member, and the specific member type of the buffer 157 is not limited by the present application.
[0054] Also, see Figures 1-3 As shown, the present application also provides a test line body, which includes a feeding device 100 as described in the above technical solution, and the test line body is used for product testing and feeding operations.
[0055] The above-mentioned test line body can adjust the gap size between the supporting plate 120 and the unloading module 110 through the adjusting part 130, so as to adjust the supporting plate 120 to a horizontal position relative to the unloading module 110, thereby ensuring the horizontality of the supporting plate 120 relative to the unloading module 110, and then making the empty tray plate supported on the supporting plate 120 horizontal relative to the unloading module 110. When unloading the product, the product can be placed horizontally in the supporting cavity of the empty tray plate, and the product will not have any undesirable phenomena such as overlapping or jamming, thereby ensuring the accuracy of the unloading position of the product.
[0056] The following combination Figures 1-7 The unloading action of the unloading device 100 provided in the present application for the product is described in detail:
[0057] First, load the empty tray onto the carrier plate 120, and adjust the gap between the carrier plate 120 and the unloading module 110 by using the adjusting member 130, so as to adjust the carrier plate 120 to a horizontal position relative to the unloading module 110, and ensure the horizontality of the carrier plate 120 relative to the unloading module 110; then, unload the multiple products to be unloaded into the multiple bearing cavities of the empty tray in turn, and switch to the full tray after the multiple bearing cavities of the empty tray are all filled with products; then, the driving module 112 drives the fixing frame 111 to move, and the fixing frame 111 drives the full tray to move into the silo 151 to prepare for unloading; continue, after a preset number of full trays are stacked in the silo 151, pull the support plate 152 to the outside of the silo 151, and on the support plate 152, When the pallet 152 is in the first state, the sensing module 156 senses the position of the pallet 152, and feeds back the position information of the pallet 152 in the first state to the first limiter 1552, and the first limiter 1552 cooperates with the stopper 1521 to lock the pallet 152 in the first state to perform the unloading operation of the full tray carrying the product; finally, after the unloading of the full tray in the silo 151 is completed, the pallet 152 is pushed into the inner side of the silo 151, and when the pallet 152 is in the second state, the sensing module 156 senses the position of the pallet 152, and feeds back the position information of the pallet 152 in the second state to the second limiter 1553, and the second limiter 1553 cooperates with the stopper 1521 to lock the pallet 152 in the second state to perform the loading operation of the full tray again.
[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
