Description

Technical Field

[0001] This invention relates to the field of automatic testing equipment technology, and in particular to a feeding device and testing equipment. Background Technology

[0002] After semiconductor wafers are manufactured, they need to be placed on trays and transferred to testing equipment for visual inspection to ensure they pass quality checks before leaving the factory. The testing equipment typically includes a testing unit with feeding devices on both the inlet and outlet sides. The feeding device on the inlet side stacks several trays containing products to be tested, feeding the trays one by one to the feeding station for the testing unit, and collecting empty trays. The feeding device on the outlet side stacks several empty trays, feeding the trays one by one to the unloading station for the testing unit, and collecting full trays.

[0003] For example, Chinese utility model patent CN202120408557.4 discloses an automatic tray supply and stacking device, which includes a tray supply module, a translation conveying mechanism and a tray stacking module. The tray supply module is used to lower the trays one by one to the translation conveying mechanism, and the tray stacking module is used to collect and stack the trays on the translation conveying mechanism.

[0004] However, the lifting structure of the material tray supply module and the material tray stacking module only corresponds to a small part of the middle area of ​​the material tray. This results in poor stability and reliability of the material tray when the lifting structure is supporting and lifting the material tray, which makes it very easy for the material tray to tip over.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding device and a testing equipment that can effectively prevent the material tray from tipping over while ensuring that the feeding device is compatible with material trays of different sizes.

[0007] The objective of this invention is achieved through the following technical solution: a feeding device, comprising:

[0019] Furthermore, the receiving component includes a mounting base and a second support member rotatably connected to the mounting base. The second support member flips upward and avoids the tray in response to the lifting of the tray, and when the tray is disengaged from the second support member, the second support member is adapted to flip downward to reset and support the tray.

[0020] Each of the conveying units is provided with two receiving components arranged side by side at intervals along the Y-axis. On the Y-axis, the two ends of the support bar located at the output end of the conveying line protrude relative to the second support member.

[0021] Furthermore, the feeding device includes a receiving mechanism located between the feeding mechanism and the unloading mechanism, the receiving mechanism comprising:

[0025] A receiving platform is provided on the base and is used to support the material tray;

[0026] The drive assembly is connected to two alignment members, which move toward each other along the Y-axis in response to the drive assembly to center the tray on the receiving platform.

[0027] In addition, the present invention also provides a detection device, comprising:

[0028] The detection device has an inlet side and an outlet side;

[0032] Furthermore, two feeding devices are arranged side by side on the discharge side to receive qualified products and unqualified products, respectively.

[0033] Furthermore, the detection device includes:

[0034] The lower transfer mechanism is adapted to support and transfer the products transported by the loading and handling device;

[0035] An upper camera mechanism is located above the transfer path of the lower transfer mechanism to detect the front of the product;

[0036] The first side camera mechanism consists of two cameras, located on either side of the transfer path of the lower transfer mechanism, to detect two sides of the product.

[0037] The upper transfer mechanism is adapted to grasp the product on the lower transfer mechanism and drive it to rotate 90°.

[0038] The lower camera mechanism is located below the transfer path of the upper transfer mechanism to detect the back of the product;

[0039] The second side camera mechanism consists of two cameras, located on either side of the transfer path of the upper transfer mechanism, to detect the other two sides of the product.

[0040] The transfer mechanism is located between the upper transfer mechanism and the unloading and conveying device;

The unloading and conveying device can selectively grab the product on the transfer station or the tilting fixture.

[0048] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts the above-described structure, in which the lifting bracket can be slidably connected to the inner side of the conveying unit along the Z-axis. The lifting bracket lifts smoothly and reliably, and the lifting bracket is close to the conveying unit, so that when the lifting bracket lifts the material tray, it can be as close as possible to the side of the material tray, improving the stability of the material tray during lifting. Furthermore, the first lifting drive component is connected to a transmission plate, with both ends of the transmission plate extending towards different lifting brackets. Each end of the transmission plate has a slotted hole, and a transmission component is connected to the lifting bracket. The transmission component is embedded in the slotted hole with upper and lower limits. During the process of the first lifting drive component driving the transmission plate to lift, the lifting bracket can lift synchronously under the transmission action of the transmission component. Moreover, when the conveying unit needs to adjust the spacing, the transmission component can move along the slotted hole, thereby preventing the lifting bracket from obstructing the adjustment of the conveying unit.

[0064] Please see Figures 1 to 3 As shown, a feeding device 100 corresponding to a preferred embodiment of the present invention includes: a conveyor line 110, including two conveying sections 111 arranged side by side along the X-axis with adjustable spacing, the two conveying sections 111 cooperating to support and convey a material tray along the Y-axis; a feeding mechanism 120, disposed at the input end of the conveyor line 110, including a release component 130 and a first lifting component 140, the release component 130 being used to support and release the material tray, the first lifting component 140 being used to support the released material tray and lower it onto the conveyor line 110; and a discharging mechanism 150, disposed at the output end of the conveyor line 110, including a receiving component 160 and a second lifting component 170, the receiving component 160 being used to receive and support the material tray, the second lifting component 170 and the first lifting component 150 being used to discharge the material tray. The components 140 have the same structure and are used to lift the material trays on the conveyor line 110 to the receiving component 160. The first lifting component 140 includes a lifting bracket 141, a transmission plate 142, and a first lifting drive component 143. There are two lifting brackets 141, and each can be slidably connected to the inner side of different conveyor sections 111 along the Z-axis. The transmission plate 142 is located between the two conveyor sections 111 and is connected to the first lifting drive component 143. The two ends of the transmission plate 142 extend to different lifting brackets 141, and each end of the transmission plate 142 has a strip hole 1421 with the length direction parallel to the X-axis. A transmission component 144 is connected to the lifting bracket 141. The transmission component 144 is embedded in the strip hole 1421 with upper and lower limits and can move along the X-axis.

[0065] The present invention employs the above-described structure, in which the lifting bracket 141 can be slidably connected to the inner side of the conveying section 111 along the Z-axis. The lifting bracket 141 lifts and lowers smoothly and reliably, and the lifting bracket 141 is close to the conveying section 111, so that when the lifting bracket 141 lifts and lowers the material tray, it can be as close as possible to the side of the material tray, improving the stability of the material tray lifting and lowering process. In addition, the first lifting drive member 143 is connected to the drive plate 142, and the two ends of the drive plate 142 extend to different lifting brackets 141 respectively. The two ends of the drive plate 142 are provided with strip holes 1421. The lifting bracket 141 is connected to the drive member 144, and the drive member 144 is embedded in the strip hole 1421 with upper and lower limits. During the process of the first lifting drive member 143 driving the drive plate 142 to lift and lower, the lifting bracket 141 can lift and lower synchronously under the transmission action of the drive member 144. When the conveying section 111 needs to adjust the spacing, the drive member 144 can move along the strip hole 1421, thereby avoiding the lifting bracket 141 from obstructing the adjustment of the conveying section 111.

[0066] Furthermore, the conveyor line 110 includes two width adjustment components 112, located at the input and output ends of the conveyor line 110, respectively. Each width adjustment component 112 includes a bearing housing 1121, a lead screw 1122, and a lead screw slider 1123. The lead screw 1122 is rotatably mounted on the bearing housing 1121, with its axis parallel to the X-axis. The lead screw 1122 has a double-helix structure, and there are two lead screw sliders 1123, each fitted onto a different helical portion of the lead screw 1122. Each conveying section 111 is connected to a different lead screw slider 1123 to move in opposite or opposite directions along the X-axis in response to the rotation of the lead screw 1122. A handwheel or motor can be connected to the end of the lead screw 1122 to drive its rotation.

[0067] Furthermore, the release assembly 130 includes a first support member 131 and a lateral drive member 132. The first support member 131 supports the material tray, and the lateral drive member 132 is disposed on the upper side of the conveying section 111 and is throttle-connected to the first support member 131. The lateral drive member 132 is a linear cylinder, which can drive the first support member 131 to move closer to or away from the material tray along the X-axis. In this embodiment, each conveying section 111 is provided with two release assemblies 130 arranged side by side and spaced apart along the Y-axis to cooperate in supporting the material tray.

[0068] Preferably, two release components 130 near the end of the conveyor line 110 can be slidably connected to the conveyor section 111 along the Y-axis to adaptively adjust their position according to the actual size of the tray, thereby improving versatility.

[0069] Preferably, each conveying section 111 is provided with an inlet baffle 113, and the release component 130, which is located away from the end of the conveyor line 110, is arranged adjacent to the inlet baffle 113 and is located between the release component 130 and the inlet baffle 113 near the end of the conveyor line 110. A gap is left between the bottom of the inlet baffle 113 and the conveying surface of the conveyor line 110 to allow a single tray to pass through.

[0070] During material loading, the operator can push the entire stack of pallets onto the conveyor line 110 from the input end of the conveyor line 110, where it is blocked and limited by the pallet inlet baffle 113. Then, the first lifting component 140 can lift the entire stack of pallets to a preset height, and the first support member 131 of the release component 130 can extend to the bottom of the pallet to support it. When it is necessary to lower a single pallet onto the conveyor line 110, the first lifting component 140 rises and supports the pallet, and then the first support member 131 disengages from the pallet. Next, the first lifting component 140 lowers by the height of one pallet, and the first support member 131 extends back to the bottom of the pallet above the bottom pallet, so that the first lifting component 140 can lower the single pallet onto the conveyor line 110.

[0071] Furthermore, the lifting support 141 includes a lifting plate 1411 and a support bar 1412. A slide rail assembly 145 is connected between the lifting plate 1411 and the inner side of the conveying section 111. The slide rail assembly 145 is arranged along the Z-axis to stabilize the lifting plate 1411 and guide it to rise and fall reliably. The support bar 1412 is connected to the top of the lifting plate 1411 and extends along the Y-axis. Preferably, the two ends of the support bar 1412 located at the input end of the conveyor line 110 protrude from the opposite sides of the two first support members 131 on the same side, thereby further improving the stability of the lifting support 141 after supporting the material tray.

[0072] In this embodiment, the lifting plate 1411 is L-shaped, including a vertical plate and a horizontal plate, and the slide rail assembly 145 is connected between the vertical plate and the conveying part 111. The transmission member 144 is connected to the lower end of the vertical plate, the horizontal plate is connected to the upper end of the vertical plate, and the support bar 1412 is connected to the top of the horizontal plate.

[0073] The first lifting drive component 143 is a structure consisting of a motor and a lead screw assembly for precise driving. The transmission plate 142 is a long strip structure and is connected to the lead screw assembly. The transmission component 144 is connected to the bottom of the lifting plate 1411. In this embodiment, the transmission component 144 is preferably a cam bearing follower, which contacts the upper and lower ends of the strip hole 1421 respectively, and rolls along the X-axis in response to the spacing adjustment of the conveying section 111, thereby improving the smoothness of the adjustment process of the conveying section 111.

[0074] Preferably, the first lifting assembly 140 further includes a mounting frame 146 and a blocking assembly 147. The first lifting drive component 143 and the blocking assembly 147 are both disposed on the mounting frame 146 and arranged opposite to each other along the Y-axis. The blocking assembly 147 is specifically composed of a lifting cylinder and a stop block. It can rise to block the trays on the conveyor line 110 to prevent them from flowing out of the tray inlet baffle 113, or fall to allow the trays on the conveyor line 110 to flow out of the tray inlet baffle 113.

[0075] Furthermore, referring to Figure 1 , Figure 4 and Figure 5 As shown, the receiving assembly 160 includes a mounting base 161 and a second support member 162. The mounting base 161 is disposed on the upper side of the conveying section 111, and the second support member 162 is rotatably connected to the mounting base 161. The second support member 162 flips upward and avoids the tray in response to the lifting of the tray, and when the tray disengages from the second support member 162, the second support member 162 is adapted to flip downward to reset and support the tray.

[0076] Each conveying section 111 is equipped with two collection components 160 arranged side-by-side at intervals along the Y-axis. On the Y-axis, the two ends of the support bar 1412 located at the output end of the conveying line 110 protrude from opposite sides of two second support members 162 on the same side. Preferably, the two collection components 160 away from the end of the conveying line 110 can be slidably connected to the conveying section 111 along the Y-axis to adaptively adjust their position according to the actual size of the tray, thereby improving versatility.

[0077] In this embodiment, the receiving component 160 includes an elastic element 163, which is a spring connected between the second support 162 and the mounting base 161. When the tray flows under the conveyor line 110 to the receiving position directly below the receiving component 160, the second lifting component 170 can lift the tray. The second support 162 is adapted to flip upward to avoid the tray and compress the elastic element 163. When the tray moves above the second support 162, the second support 162 is adapted to reset under the rebound action of the elastic element 163 and support the tray.

[0078] However, with the above structure, when the operator drags the material tray on the second support member 162 to unload the material, the second support member 162 cannot completely cover the material tray because the receiving component 160 is arranged at intervals along the Y-axis. During the dragging process, the material tray is easy to fall into the gap between adjacent second support members 162. Therefore, the operator needs to support the bottom of the material tray, which makes unloading very inconvenient.

[0079] Preferably, the receiving component 160 further includes a second lifting drive 164 disposed on the mounting base 161. The second lifting drive 164 is a linear cylinder arranged along the Z-axis, with its output end facing downwards. The output end of the second lifting drive 164 is adapted to approach and push the second support member 162, causing the second support member 162 to flip upwards. The second lifting drive 164 and the second lifting component 170 cooperate with each other to allow the stacked trays to fall from the receiving component 160 to the conveyor line 110. The conveyor line 110 is adapted to drive the trays to flow out of the output end along the Y-axis, thereby enabling smooth and reliable unloading of the trays without manual dragging. When the unloading mechanism 150 is performing normal receiving operations, the output end of the second lifting drive 164 can retract upwards to move away from the second support member 162, so that the normal flipping of the second support member 162 is not affected by the second lifting drive 164.

[0080] In addition, each conveying section 111 is provided with a tray discharge baffle 114. The receiving component 160, located away from the end of the conveyor line 110, is arranged adjacent to the tray discharge baffle 114 and is situated between the receiving component 160 and the tray discharge baffle 114 near the end of the conveyor line 110. A gap is left between the bottom of the tray discharge baffle 114 and the conveying surface of the conveyor line 110 to allow a single tray to pass through.

[0081] Furthermore, the feeding device 100 includes a receiving mechanism 180 located between the feeding mechanism 120 and the unloading mechanism 150. The receiving mechanism 180 is capable of receiving the trays output from the feeding mechanism 120 and moving them to a designated position, as well as moving empty trays to the unloading mechanism 150.

[0082] Reference Figure 6 As shown, the receiving mechanism 180 includes a first Y-axis module 181, a first Z-axis module 182, a second Y-axis module 183, and a receiving platform 184. The first Y-axis module 181 is a linear module arranged along the Y-axis, and the first Z-axis module 182 is a linear module arranged along the Z-axis, which is driveably connected to the first Y-axis module 181. The second Y-axis module 183 includes a base 1831 and a drive assembly 1832. The base 1831 is driveably connected to the first Z-axis module 182, and the drive assembly 1832 is disposed on the base 1831. The receiving platform 184 is disposed on the base 1831 and is used to support the material tray.

[0083] The drive assembly 1832 is a motor-driven belt drive structure with two alignment members 185 connected to it. Both alignment members 185 are connected to the belt and are located on both sides of the receiving platform 184 on the Y-axis. The two alignment members 185 move towards each other along the Y-axis in response to the drive assembly 1832 to center the tray on the receiving platform 184 and improve positioning accuracy.

[0084] Furthermore, referring to Figure 7As shown, the present invention also provides a testing device, including a testing device 200, the aforementioned feeding device 100, a loading and conveying device 300, and a unloading and conveying device 400. The testing device 200 has an inlet side and an outlet side on both sides of the X-axis, respectively. The feeding device 100 has at least two components, located on the inlet side and the outlet side, respectively. The feeding device 100 on the inlet side can load a tray containing the product to be tested and unload an empty tray. The feeding device 100 on the outlet side can load an empty tray and unload a tray containing the tested product. In this embodiment, there are two feeding devices 100 on the outlet side, arranged side-by-side along the X-axis, which are used to receive products that pass the test and products that fail the test, respectively.

[0085] The loading and conveying device 300 is connected between the detection device 200 and the feeding device 100 located on the inlet side, to transport the product to be detected from the tray at a designated position of the feeding device 100 to the detection device 200. The unloading and conveying device 400 is connected between the detection device 200 and the feeding device 100 located on the outlet side, to transport the detected product to the tray at a designated position of the feeding device 100.

[0086] Furthermore, referring to Figure 8 and Figure 9 As shown, the detection device 200 includes a lower transfer mechanism 210, an upper camera mechanism 220, a first side camera mechanism 230, an upper transfer mechanism 240, a lower camera mechanism 250, a second side camera mechanism 260, and a transfer mechanism 270. The lower transfer mechanism 210 is adapted to support and transfer the product transported by the loading and handling device 300. The upper camera mechanism 220 is located above the transfer path of the lower transfer mechanism 210 to detect the front of the product. There are two first side camera mechanisms 230, which are arranged opposite each other along the Y-axis, and are located on both sides of the transfer path of the lower transfer mechanism 210 to detect two sides of the product.

[0087] The upper transfer mechanism 240 is adapted to grasp the product on the lower transfer mechanism 210 and rotate the product by 90°. The lower camera mechanism 250 is located below the transfer path of the upper transfer mechanism 240 to inspect the back of the product. There are two second-side camera mechanisms 260, which are arranged opposite each other along the Y-axis and are located on both sides of the transfer path of the upper transfer mechanism 240 to inspect the other two sides of the product.

[0091] The upper camera mechanism 220, the first side camera mechanism 230, the second side camera mechanism 260, and the lower camera mechanism 250 are arranged sequentially along the X-axis. These camera mechanisms are all conventional shooting structures, and will not be described in detail here. By setting up the first side camera mechanism 230 and the second side camera mechanism 260 to detect different sides of the product respectively, this invention can effectively improve the detection cycle time of the detection device 200 and increase detection efficiency.

[0092] Furthermore, since some processes require specific placement of the inspected products in both directions, in this embodiment, the transfer mechanism 270 includes a transfer table 271, a third Y-axis module 272, a flipping fixture 273, and a flipping module 274. The transfer table 271 is used to hold the product, and its structure is the same as or similar to that of the transfer table 212; details will not be repeated here. The third Y-axis module 272 is a linear module arranged along the Y-axis and is driveably connected to the transfer table 271.

The flipping fixture 273 is adapted to pick up the products and flip them 180° under the drive of the flipping module 274, so that the back of the products are facing upwards. The unloading and conveying device 400 can selectively grip products on the transfer table 271 or the flipping fixture 273.

[0093] Furthermore, referring to Figure 10As shown, the loading and conveying device 300 includes a third X-axis module 310, a fourth Y-axis module 320, ZR actuators 330, and a second suction nozzle 340. Both the third X-axis module 310 and the fourth Y-axis module 320 are linear modules, with the fourth Y-axis module 320 being drive-connected to the third X-axis module 310. The output end of the fourth Y-axis module 320 is connected to a base 350. Multiple ZR actuators 330 are arranged side-by-side along the X-axis on the base 350. The second suction nozzle 340 is drive-connected to each ZR actuator 330 in a one-to-one correspondence. The ZR actuator 330 is a voice coil actuator, and the second suction nozzle 340 can move up and down along the Z-axis and rotate around the Z-axis in response to the drive of the ZR actuator 330. In this embodiment, the second suction nozzle 340 corresponds one-to-one with a storage position on the transfer table 212.

[0094] Furthermore, the structure of the unloading and conveying device 400 is similar to that of the loading and conveying device 300, and will not be described in detail here.

[0095] The working process of the testing equipment of the present invention is as follows: The feeding device 100 on the inlet side transfers the tray containing the product to be tested to the loading station, and the feeding device 100 on the outlet side transfers the empty tray to the unloading station; the loading and conveying device 300 moves to the loading station to pick up the product in the tray and transport it to the transfer platform 212 of the lower transfer mechanism 210; the transfer platform 212 passes sequentially along the X-axis through the upper camera mechanism 220 and the first side camera mechanism 230 to perform appearance inspection on the front and two of the sides of the product; then the picking and placing component 243 of the upper transfer mechanism 240 picks up the product on the transfer platform 212 and drives the product to rotate. The product is inspected at 90° and flows sequentially along the X-axis through the second side camera mechanism 260 and the lower camera mechanism 250 to inspect the other two sides and the back of the product. Then, the pick-and-place assembly 243 moves to the transfer table 271 and places the inspected product on the transfer table 271. The unloading and conveying device 400 removes the product and places it into the tray corresponding to the unloading station according to the inspection results. When the product needs to be flipped before unloading, the transfer table 271 moves to the flipping fixture 273. The flipping fixture 273 can pick up the product and flip it. Then, the unloading and conveying device 400 removes the flipped product from the flipping fixture 273.
