Description

Technical Field

[0001] This application relates to the field of automated testing technology, and in particular to a feeding unit, clamping device and testing equipment. Background Technology

[0002] Various 3C products, such as televisions, computers, and mobile phones, are equipped with displays for image display. After the display is assembled and before leaving the factory, it needs to undergo a power-on test to check whether the display is functioning properly. Specifically, the display is clamped in a fixture and electrically connected to a power-on testing machine. The power-on testing machine writes a program to the display to make it display a predetermined image. Then, a detection camera captures the image displayed on the display and identifies whether the displayed image meets the requirements, thereby screening out defective products that do not meet the requirements.

[0003] However, current display testing equipment lacks cycle time optimization, resulting in a waiting period between the material handling mechanisms and the next product before they can begin handling the next product during the feeding, transporting, or clamping process. This leads to low feeding and testing efficiency. As products and factories continue to be optimized and upgraded, the production efficiency of the existing testing equipment can no longer meet the growing demand for mass production. Utility Model Content

[0004] Based on this, the purpose of this application is to provide a feeding unit, including a clamping device for the feeding unit and a testing device including the clamping device, to solve the technical problem that the existing testing equipment has poor cycle optimization, resulting in low feeding and testing efficiency.

[0005] According to one aspect of this application, a feeding unit is provided, including a first conveying mechanism and a second conveying mechanism;

[0006] The first conveying mechanism has a loading end and a first transfer end arranged opposite to each other, and the second conveying mechanism has a second transfer end adjacent to the first transfer end and a feeding end away from the first transfer end; the first conveying mechanism is used to convey the product from the loading end to the first transfer end, and the second conveying mechanism is used to grab the product from the first transfer end and convey the product from the second transfer end to the feeding end;

[0007] The first conveying mechanism includes two parallel feeding modules, which are configured to alternately convey the product from the loading end to the first transfer end, such that whenever the second conveying mechanism needs to pick up the product from the first transfer end, the product has already been conveyed to the first transfer end by one of the feeding modules.

[0008] In one embodiment, the second conveying mechanism includes a conveying module and a flipping module arranged sequentially from the second transfer end to the feeding end. The conveying module is used to grab the product from the first transfer end and convey the product to a position close to the flipping module. The flipping module is used to flip the product so that the orientation of the opposite two side surfaces of the product is interchanged.

[0009] In one embodiment, a transfer platform is provided between the transport module and the flipping module. The transfer platform is used to place the product picked up by the transport module from the first transfer end, so that the flipping module can pick up the product from the transfer platform and flip the product.

[0010] In one embodiment, the feeding unit further includes a first positioning camera disposed near the feeding end, the first positioning camera being used to take a picture of the product after a downstream device grabs the product from the feeding end, so as to record the position of the product on the downstream device.

[0011] In one embodiment, the feeding unit further includes a cable arranging module, which is disposed adjacent to the first conveying mechanism and between the feeding end and the first transfer end. The cable arranging module includes a cable pressing head assembly and a cable arranging assembly. The cable pressing head assembly is movable in the vertical direction to press the product when the product passes through the cable arranging module. The cable arranging assembly is movable in both the vertical and horizontal directions to fold or unfold the cables on the product.

[0012] According to another aspect of this application, a clamping device is provided, including a clamping unit and a feeding unit as described in any of the above embodiments, wherein the clamping unit is disposed adjacent to the feeding unit and located near the feeding end; the clamping unit includes a robot arm and a fixture conveyor line, the fixture conveyor line being used to provide a fixture, and the robot arm being used to grip the product from the feeding end and clamp the product in the fixture.

[0013] In one embodiment, the fixture conveyor line includes an upper conveyor line, a lower conveyor line, and a lifting module. The upper conveyor line is spaced above the lower conveyor line, and the lifting module is located at the same end of the upper and lower conveyor lines. The lifting module is used to lift the fixture conveyed on the lower conveyor line to the upper conveyor line.

[0014] In one embodiment, the number of upper conveyor lines is greater than the number of lower conveyor lines, and the number of lifting modules corresponds to the number of upper conveyor lines; the fixture conveyor line further includes a switching module disposed between the lower conveyor lines and the lifting modules, the switching module having a platform that can reciprocate along a straight line so that the platform can be sequentially positioned on each of the lifting modules, thereby providing the fixtures conveyed from the lower conveyor lines to each of the lifting modules sequentially.

[0015] In one embodiment, at least one second positioning camera is provided above each of the upper conveyor lines. The second positioning camera is used to take pictures of the fixture before the product is clamped in the fixture and to take pictures of the product after the product is clamped in the fixture, so as to confirm whether the product is properly clamped in the fixture.

[0016] According to another aspect of this application, a testing device is provided, comprising a testing apparatus and a clamping device as described in any of the above embodiments, wherein the testing apparatus is disposed adjacent to the clamping unit of the clamping device; the testing apparatus is used to test the product after the product is clamped in the fixture.

[0017] The aforementioned feeding unit, clamping device including the feeding unit, and testing equipment including the clamping device, by setting the first conveying mechanism of the feeding unit as two parallel feeding modules, and configuring the two feeding modules to alternately convey products from the loading end to the first transfer end, ensures that whenever the second conveying mechanism needs to pick up a product from the first transfer end for further conveying, there is always a product being conveyed to the first transfer end by one of the feeding modules. This allows the second conveying mechanism to immediately convey the next product after conveying one product, thus optimizing the cycle time, avoiding waiting, significantly improving the efficiency of product feeding, and improving the efficiency of testing, meeting the growing demand for mass production.

[0035] This application provides a feeding unit, a clamping device, and a testing device. The testing device includes a testing unit and a clamping device arranged adjacent to each other. The clamping device includes a feeding unit. The testing unit is used to test electronic products to determine whether the products have defects, so that defective products can be rejected in time before leaving the factory, thereby preventing defective products from entering the market. The clamping device is used to clamp the products to be tested in a fixture to fix the products before testing, so as to ensure the testing accuracy of the products when they are tested. The feeding unit is used to transport and feed the products.

[0036] The following description uses a testing device for testing the display screen of 3C products as an example to illustrate the structure of the feeding unit and clamping device in this application. It is understood that in other embodiments, the testing device of this application is not limited to testing the display screen of 3C products; it can also test any product. Similarly, the clamping device is not limited to use in testing equipment; it can be used in any situation requiring product clamping and fixing. Furthermore, the feeding unit is not limited to use in the clamping device; it can be used in any situation requiring product feeding. All of the above are not limited to these limitations.

[0037] See Figure 1 , Figure 1 The present application shows a clamping device 10 provided in an embodiment of the present application. The clamping device 10 provided in an embodiment of the present application includes a feeding unit 100 and a clamping unit 200 arranged adjacent to each other. The feeding unit 100 is used to provide a product, and the clamping unit 200 is used to provide a fixture and clamp and fix the product in the fixture so as to ensure the testing accuracy of the product when it is tested by the testing device in subsequent processes.

[0038] Further, see Figure 2 and Figure 3 , Figure 2 This illustration shows a schematic diagram of the structure of the feeding unit 100 in an embodiment of this application. Figure 3A top view of the feeding unit 100 is shown. In this embodiment, the feeding unit 100 includes a first conveying mechanism 110 and a second conveying mechanism 120. The first conveying mechanism 110 has a loading end 110a and a first transfer end 110b disposed opposite to each other. The second conveying mechanism 120 has a second transfer end 120a adjacent to the first transfer end 110b and a feeding end 120b away from the first transfer end 110b. The clamping unit 200 is disposed adjacent to the feeding end 120b. The first conveying mechanism 110 is used to convey the product from the loading end 110a to the first transfer end 110b. The second conveying mechanism 120 is used to grab the product from the first transfer end 110b and convey the product from the second transfer end 120a to the feeding end 120b, so that the clamping device 10 can grab the product and clamp it in the fixture nearby.

[0039] In some embodiments, the first conveying mechanism 110 includes a feeding module, such as Figure 4 As shown, the feeding module is a linear module with a positioning carrier 110c movably mounted on it. The positioning carrier 110c is used to carry the product. The linear module is a common existing drive source, which will not be described in detail here. Driven by the linear module, the positioning carrier 110c can carry the product and move along a straight line to transport the product from the loading end 110a to the first transfer end 110b. Preferably, there are two feeding modules, which are configured to alternately transport the product from the loading end 110a to the first transfer end 110b, so that whenever the second conveying mechanism 120 needs to pick up a product from the first transfer end 110b, a product has already been transported to the first transfer end 110b by one of the feeding modules.

[0040] Here, combined with Figure 3 As shown, the two feeding modules are defined as the first feeding module 111 and the second feeding module 112, respectively. It is easy to understand that when the second conveying mechanism 120 removes the product transported by the first feeding module 111 to the first transfer end 110b and is transporting it to the feeding end 120b, the first feeding module 111 returns to the upper feeding end 110a to prepare for transporting new products, while the second feeding module 112 is transporting products to the first transfer end 110b. When the second conveying mechanism 120 finishes transporting the product to the feeding end 120b and is preparing to transport a product from the first transfer end 110b to the second transfer end 120a, the second feeding module 112 has already transported the product to the first transfer end 110b. In this way, the second conveying mechanism 120 can immediately continue transporting products. This cycle repeats continuously, with both feeding modules and the second conveying mechanism 120 continuously transporting products, thus avoiding waiting and significantly improving the transport and feeding speeds.

[0041] Under certain process requirements, products need to have different faces facing upwards during the preceding and subsequent testing processes. Therefore, regarding the structure of the second conveying mechanism 120, in the embodiments of this application, the second conveying mechanism 120 includes a conveying module 121, a transfer table 122, and a flipping module 123 arranged sequentially from the second transfer end 120a to the feeding end 120b. One end of the conveying module 121 serves as the second transfer end 120a, and the flipping module 123 serves as the feeding end 120b. Combined with... Figure 5 As shown, the conveying module 121 also has a structure in which an adsorption component 1211 is movably provided on the linear module. The adsorption component 1211 is used to grab the product from the first transfer end 110b and transport the product to a position close to the flipping module 123; combined with Figure 6 As shown, the transfer station 122 has a product placement position 1221, which is used to place products grabbed from the first transfer end 110b by the adsorption component 1211; combined with Figure 7 As shown, the flipping module 123 has a flipping positioning platform 1231, which can flip the product after it is picked up from the transfer table 122, for example, flipping it 180°, so that the orientation of the opposite two sides of the product can be interchanged.

[0042] Preferably, the transfer station 122 is equipped with a lifting cylinder 1222 under the two product placement positions 1221. The lifting cylinder 1222 can lift the two product placement positions 1221 upwards by a certain distance to ensure that the flip positioning platform 1231 can adsorb the products placed on the product placement positions 1221.

[0043] Thus, by setting up the transfer station 122, products can be temporarily stored. After the adsorption component 1211 of the conveying module 121 places the product on the transfer station 122, it can immediately return to the second transfer end 120a without waiting for the flipping module 123 to adsorb the product before returning to the second transfer end 120a. Therefore, the waiting time can be reduced and the feeding efficiency can be improved.

[0044] Please continue reading. Figure 3 In a preferred embodiment, the first conveying mechanism 110 and the second conveying mechanism 120 are perpendicular to each other, that is, the conveying path of the product is "L" shaped, which can make full use of space and make the structure of the feeding unit 100 more compact.

[0045] It should be noted that the structure of the second conveying mechanism 120 is not limited to the structure shown in the embodiment in the figure. For example, when there is no need to flip the product, the flipping module 123 may not be provided, and only the conveying module 121 and the transfer station 122 may be provided, or only the conveying module 121 may be provided; or only the conveying module 121 and the flipping module 123 may be provided. The structure of the conveying module 121 may be the same as the structure of the feeding module in the first conveying mechanism 110. None of the above are limited.

[0046] It is worth noting that when the product is a 3C electronic product, it typically has cables. In some cases, to facilitate product transportation, the cables are usually folded in the previous process. Therefore, in an optional embodiment, such as Figure 2 and Figure 3 As shown, the feeding unit 100 also includes a cable management module 130, which is disposed adjacent to the first conveying mechanism 110 and between the loading end 110a and the first transfer end 110b. The cable management module 130 includes a cable pressing head assembly (not shown) and a cable management assembly (not shown). Both the cable pressing head assembly and the cable management assembly are connected to a drive source, such as a linear module. The drive source connected to the cable pressing head assembly can drive the cable pressing head assembly to move vertically, so that the product is pressed down when it passes through the cable management module 130. The drive source connected to the cable management assembly can drive the cable management assembly to move simultaneously in both vertical and horizontal directions, so that the cables on the product can be unfolded when the product is pressed down. Of course, when there is a need to fold the cables, the cable management assembly can also move simultaneously in both vertical and horizontal directions to fold the cables on the product, changing the cable from an unfolded state to a folded state.

[0047] Furthermore, such as Figure 2 As shown, a manual feeding mechanism 140 is also provided at the first transfer end 110b of the first conveying mechanism 110. The manual feeding mechanism 140 has a manual feeding drawer, and the manual feeding drawer has a product cavity for accommodating products. The purpose of setting up the manual feeding mechanism 140 is that, in some cases, when automated feeding is not performed, it is necessary to manually feed the products to achieve purposes such as data confirmation. When manual feeding is required, the operator opens the manual feeding drawer, puts the product into the product cavity of the manual feeding drawer, and then pushes the manual feeding drawer so that the adsorption component 1211 of the second conveying mechanism 120 adsorbs the replenished product and places it on the feeding module of the first conveying mechanism 110. The feeding module then carries the product to the position of the cable arrangement module 130 for cable arrangement and then transports it to the first transfer end 110b, where it is transported by the second conveying mechanism 120 to the feeding end 120b.

[0048] Furthermore, after the product is flipped by the flipping module 123, the clamping unit 200, as a downstream device, needs to grab the product from the feeding end 120b and clamp it in the fixture. In order to ensure clamping accuracy and ensure that the product can be clamped in place, the feeding unit 100 is also provided with a first positioning camera 150 near the feeding end 120b. In this embodiment, the first positioning camera 150 is used to take pictures from below the product after the clamping unit 200 grabs the product from the feeding end 120b, so as to record the position of the product on the clamping unit 200, which helps to ensure that the product can be accurately clamped into the fixture.

[0049] As for the clamping unit 200, combined with Figure 2 and Figure 8 As shown, the clamping unit 200 includes a robot arm 210 and a fixture conveyor line 220. The fixture conveyor line 220 provides fixtures, and the robot arm 210 grips products from the feeding end 120b and clamps the products in the fixture. It can be seen that after the robot arm 210 grips a product, it first grips the product above the first positioning camera 150, which then takes a picture of the product to record its position on the robot arm 210. If the product's position on the robot arm 210 is not acceptable after taking the picture, the product needs to be rejected. To promptly reject products with unacceptable positions, accordingly, such as... Figure 2 and Figure 3 As shown, the feeding unit 100 also includes an NG module 160, which is used to discharge products that fail the photographic inspection from the feeding unit 100. In the embodiment shown in the figure, the NG module 160 has a conveyor belt structure. To save space, the extension direction of the NG module 160 is the same as the extension direction of the second conveying mechanism 120, but the conveying direction is opposite to that of the second conveying mechanism 120. The defective products are conveyed from one side located at the feeding end 120b to one side located at the second transfer end 120a, and then output outside the feeding unit 100.

[0050] Please continue reading. Figure 8In the embodiment shown in the figure, the fixture conveyor line 220 includes an upper conveyor line 221, a lower conveyor line 222, and a lifting module 223. The upper conveyor line 221 is spaced above the lower conveyor line 222, and the lifting module 223 is located at the same end of the upper conveyor line 221 and the lower conveyor line 222. The upper conveyor line 221 has a clamping station 221a, which is used to convey fixtures to the clamping station 221a. After the product is clamped in the fixture, the fixture with the product clamped is conveyed to the testing device for testing. After the product is tested, it is removed from the fixture. The lower conveyor line 222 is used to return empty fixtures so that the fixtures can be reused. The lifting module 223 is used to lift the fixtures conveyed by the lower conveyor line 222 onto the upper conveyor line 221. In the embodiment shown in the figure, the lifting module 223 is also a structure in which a lifting carrier 2231 is movably provided on the linear module. The lifting carrier 2231 can be raised and lowered under the drive of the linear module so as to continuously transport the fixture on the lower conveyor line 222 to the upper conveyor line 221.

[0051] In a preferred embodiment, such as Figure 8 As shown, the number of upper conveyor lines 221 is greater than the number of lower conveyor lines 222. The number of lifting modules 223 corresponds to the number of upper conveyor lines 221. In the embodiment shown, there is one lower conveyor line 222, two upper conveyor lines 221, and two lifting modules 223. Each lifting module 223 corresponds to one upper conveyor line 221, thus enabling the fixture to be conveyed to the corresponding upper conveyor line 221. This design saves costs by using only one lower conveyor line 222 to return empty fixtures. Furthermore, by increasing the number of upper conveyor lines 221 and lifting modules 223, the number of clamping stations 221a can be increased, allowing multiple products to be clamped into the fixture and tested by the testing device in a shorter time, thereby improving testing efficiency.

[0052] In order to divert the fixtures on the lower conveyor line 222 to each of the upper conveyor lines 221, the fixture conveyor line 220 also includes a switching module 225 located between the lower conveyor line 222 and the lifting module 223. The switching module 225 also includes a linear module, on which a platform 2251 is movably provided. The platform 2251 can reciprocate along a straight line under the drive of the linear module. Specifically, it reciprocates along a direction perpendicular to the extension of the upper conveyor line 221 and the lower conveyor line 222, so that the platform 2251 can sequentially be positioned on each lifting module 223, thereby providing the fixtures conveyed from the lower conveyor line 222 to each lifting module 223 in sequence.

[0053] More preferably, to further ensure that the product is properly clamped into the fixture, at least one second positioning camera 224 is provided above each upper conveyor line 221. Each second positioning camera 224 is located above a clamping station 221a. It is used to take pictures of the fixture before the product is clamped into the fixture to record the position information of the fixture on the upper conveyor line 221. Then, after the product is clamped into the fixture, the second positioning camera 224 takes pictures of the product again. Based on the position information of the product on the robot arm 210 recorded by the first positioning camera 150 and the position information of the fixture recorded by the second positioning camera 224, the relative position of the product and the fixture is obtained to confirm whether the product is properly clamped in the fixture.

[0054] To further improve clamping and testing efficiency, such as Figure 9 As shown, each upper conveyor line 221 has two clamping stations 221a, so there are a total of four clamping stations 221a on the two upper conveyor lines 221. There are also four corresponding second positioning cameras 224. Each second positioning camera 224 is used to photograph the fixture and product at a corresponding clamping station 221a. It is easy to see that by using the above setup, the number of clamping stations 221a increases. As long as a fixture arrives at a clamping station 221a, the product can be clamped into the corresponding fixture, and the corresponding second positioning camera 224 can take a picture, thereby significantly improving work efficiency.

[0055] In addition, in one embodiment of this application, see further reference. Figure 9 Since each upper conveyor line 221 has two clamping stations 221a, there are correspondingly two robotic arms 210. This allows the two robotic arms 210 to simultaneously grasp two products and place them into fixtures on each upper conveyor line 221 corresponding to a clamping station 221a. Similarly, the flipping module 123 has two flipping positioning platforms 1231, the transfer table 122 also has two product placement positions 1221, the handling module 121 has two adsorption components 1211, each feeding module has two positioning carriers 110c, and the NG module 160 also has two, thus enabling the handling of an even number of products at a time. Of course, the number of these structures is not limited to two and can be set according to specific needs.

[0056] The following is combined Figures 1 to 9 The working process of the clamping device 10 provided in this application will be described.

[0057] In the first step, the two feeding modules of the first conveying mechanism 110 alternately transport the product from the loading end 110a to the first transfer end 110b; then the conveying module 121 of the second conveying mechanism 120 transports the product to the transfer table 122 and places it on the transfer table 122. The flipping positioning platform 1231 of the flipping module 123 rotates to the transfer table 122 to adsorb the product. Then the flipping positioning platform 1231 rotates 180° to flip the product 180°.

[0058] In the second step, the robot arm 210 picks up the product and places it above the first positioning camera 150. The first positioning camera 150 records the position of the product on the robot arm 210. If the position of the product on the robot arm 210 is not qualified, the robot arm 210 places the unqualified product on the NG module 160, and the NG module 160 outputs the product to the outside of the feeding unit 100. At the same time, the fixture conveyor line 220 conveys the fixture to the clamping station 221a, and the second positioning camera 224 takes a picture of the fixture and records the position information of the fixture on the fixture conveyor line 220.

[0059] Third, if the product is positioned correctly on the robot 210, the robot 210 will pick up the product and place it above the clamping station 221a, then clamp the product in the fixture. The second positioning camera 224 will take another picture to confirm whether the product is properly clamped in the fixture. If it is properly clamped, the fixture will carry the product to the downstream testing station for testing by the testing device.

[0060] In summary, the feeding unit 100, the clamping device 10 including the feeding unit 100, and the testing equipment including the clamping device 10 provided in this application have optimized the existing equipment structure. After optimization, compared with the original testing equipment, the production speed can be doubled with the same equipment floor space, thereby greatly improving the clamping efficiency and testing efficiency of the products. This is conducive to improving the factory's productivity and plant utilization rate, and meets the growing demand for mass production of products.
